Description
本申请涉及通信技术领域,特别涉及一种激活和释放非动态调度数据传输的方法及装置。This application relates to the field of communication technology, and in particular to a method and device for activating and releasing non-dynamic scheduling data transmission.
在蜂窝网移动通信系统中,上行数据传输的方式包括基于动态授权(grant based,GB)或动态调度的数据传输,以及非动态调度数据传输。非动态调度数据传输包括半持续调度SPS(semi-persistent scheduling)数据传输或免授权(grant-free,GF)数据传输。其中,基于动态授权(grant based,GB)或动态调度的数据传输的过程包括:终端有上行数据传输需求时,通常向基站发送调度请求(scheduling reqeust,SR)或者上报非空的缓存状态报告(buffer state report,BSR),基站在收到SR或者BSR后向终端发送下行控制信息(downlink control information,DCI),DCI中携带上行授权(UL grant),用于授权终端在指定的时频资源上使用指定的传输参数,如指定的调制编码方案MCS(Modulation and Coding Scheme)等,发送上行数据。由于动态调度可以高效利用终端与基站之间的实时信道信息,为终端的每次传输指定合适的时频资源的位置、大小,以及合适的传输参数等,动态调度的上行传输通常具有更高的可靠性。In a cellular network mobile communication system, uplink data transmission methods include data transmission based on dynamic grant (grant-based, GB) or dynamic scheduling, and non-dynamic scheduling data transmission. Non-dynamic scheduling data transmission includes semi-persistent scheduling (SPS) data transmission or grant-free (GF) data transmission. Among them, the process of data transmission based on dynamic grant (grant based, GB) or dynamic scheduling includes: when the terminal has an uplink data transmission demand, it usually sends a scheduling request (scheduling request, SR) or reports a non-empty buffer status report ( Buffer state report, BSR). After receiving the SR or BSR, the base station sends downlink control information (DCI) to the terminal. The DCI carries an uplink grant (UL grant) to authorize the terminal to use the specified time-frequency resources. Use the specified transmission parameters, such as the specified modulation and coding scheme MCS (Modulation and Coding Scheme), etc., to send uplink data. Because dynamic scheduling can efficiently use the real-time channel information between the terminal and the base station, and specify the location, size, and transmission parameters of the appropriate time-frequency resources for each transmission of the terminal, the dynamic scheduling of uplink transmission usually has a higher reliability.
而非动态调度的数据传输的过程包括:基站通过高层信令和/或物理层信令以半静态(semi-static)的方式为终端配置上行数据传输所使用的时频资源、以及传输参数等,终端有上行数据传输需求时,不需要经历向基站发送SR或BSR,并且不需要等待上行授权的过程,而是直接使用半静态配置的时频资源和传输参数向基站发送数据,实现数据的即来即走,从而达到降低传输时延、信令开销和终端功耗的目的。The non-dynamically scheduled data transmission process includes: the base station configures the time-frequency resources and transmission parameters used for uplink data transmission for the terminal in a semi-static manner through high-level signaling and/or physical layer signaling. When the terminal has uplink data transmission requirements, it does not need to go through the process of sending SR or BSR to the base station, and does not need to wait for the uplink authorization process. Instead, it directly uses the semi-statically configured time-frequency resources and transmission parameters to send data to the base station to achieve data recovery. Come and go, so as to achieve the purpose of reducing transmission delay, signaling overhead and terminal power consumption.
为同时支持多种对时延和可靠性有不同需求的业务,业界考虑在5G通信中支持在同一个带宽部分(Bandwidth Part)上允许有非动态调度传输的多套配置参数(例如,12套)。这种情况下,基站会为每一套配置参数建立索引(index)或标识(ID),并将索引或标识信息和其对应的配置参数下发给终端。基站可以基于各套配置参数对应的索引或者标识,进行相应配置参数激活或者释放。如何节省用于激活或者释放非动态调度传输的信令开销,正成为业界关心的问题。In order to support multiple services with different requirements for delay and reliability at the same time, the industry is considering supporting multiple sets of configuration parameters (for example, 12 sets) that allow non-dynamic scheduling transmission on the same bandwidth part in 5G communications. ). In this case, the base station will create an index (index) or identification (ID) for each set of configuration parameters, and deliver the index or identification information and its corresponding configuration parameters to the terminal. The base station can activate or release corresponding configuration parameters based on the index or identification corresponding to each set of configuration parameters. How to save the signaling overhead for activating or releasing non-dynamic scheduling transmission is becoming a concern of the industry.

其中,在本申请实施例中,术语“数据传输”还可以描述为“通信”、“信息传输”或“传输”。该技术方案可用于进行调度实体和从属实体间的无线通信,本领域技术人员可以将本申请实施例提供的技术方案用于进行其它调度实体和从属实体间的无线通信,例如宏基站和微基站之间的无线通信,例如第一终端和第二终端间的无线通信。Among them, in the embodiments of the present application, the term "data transmission" can also be described as "communication", "information transmission" or "transmission".

本申请实施例中,基站的上行数据传输可以采用动态调度和非动态调度的数据传输。动态调度也可以称为GB。In the embodiment of the present application, the uplink data transmission of the base station may adopt dynamic scheduling and non-dynamic scheduling data transmission. Dynamic scheduling can also be called GB.
如图2所示,动态调度的上行数据传输可以包括以下过程:As shown in Figure 2, the dynamically scheduled uplink data transmission may include the following processes:
S201、当终端有上行数据传输需求时,通常会通过物理上行控制信道(physical uplink control channel,PUCCH)向基站发送调度请求(scheduling request,SR),或者终端会通过物理上行共享信道(physical uplink shared channel,PUSCH)向基站上报非空的BSR。基站接收终端发送的SR/BSR。S201. When the terminal has a demand for uplink data transmission, it usually sends a scheduling request (SR) to the base station through a physical uplink control channel (PUCCH), or the terminal will use a physical uplink shared channel (physical uplink shared channel) channel, PUSCH) to report a non-empty BSR to the base station. The base station receives the SR/BSR sent by the terminal.
BSR通常通过媒体接入控制(medium access control,MAC)层信令发送,携带在数据包包头的媒体接入层控制单元(MAC control element,MAC CE)中BSR is usually sent through media access control (MAC) layer signaling and carried in the media access layer control element (MAC CE) in the packet header of the data packet
S202、基站收到终端发送的SR或非空的BSR后,通过下行物理控制信道(physical downlink control channel,PDCCH)向终端发送DCI。S202: After receiving the SR or non-empty BSR sent by the terminal, the base station sends DCI to the terminal through a physical downlink control channel (PDCCH).
DCI中携带上行授权(UL grant),用于授权终端在指定的时频资源上使用指定的传输参数发送上行数据。例如使用指定的调制编码方案(modulation and coding scheme,MCS)发送上行数据。The DCI carries an uplink grant (UL grant), which is used to authorize the terminal to send uplink data using specified transmission parameters on specified time-frequency resources. For example, a specified modulation and coding scheme (MCS) is used to send uplink data.
S203、终端根据DCI在指定的时频资源上使用指定的传输参数,通过PUSCH发送上行数据。S203. The terminal uses the specified transmission parameters on the specified time-frequency resources according to the DCI to send uplink data through the PUSCH.
由于动态调度可以高效利用终端与基站之间的实时信道信息,为终端的每次传输指定合适的时频资源的位置、大小,以及合适的传输参数等,动态调度的上行传输通常具有更高的可靠性。Because dynamic scheduling can efficiently use the real-time channel information between the terminal and the base station, and specify the location, size, and transmission parameters of the appropriate time-frequency resources for each transmission of the terminal, the dynamic scheduling of uplink transmission usually has a higher reliability.
基于动态授权的上行数据传输过程中,终端在发送数据之前,需要向基站发送SR或BSR,再由基站通过DCI进行授权,这一过程会引入时延和PDCCH信令开销。同时,由于PDCCH的接收通常需要终端在不同时频资源上按照不同控制信道单元CCE(Control Channel Element)聚合等级(Aggregation Level)、和/或不同的DCI格式(Format)、和/ 或不同的DCI长度、和/不同的无线网络临时标识(Radio Network Temporary Identifier)进行盲检测,因此需要耗费大量的功耗。采用非动态调度的数据传输能够降低时延、降低信令开销以及降低终端功耗。In the uplink data transmission process based on dynamic authorization, the terminal needs to send SR or BSR to the base station before sending data, and the base station will authorize through DCI. This process will introduce delay and PDCCH signaling overhead. At the same time, because the reception of PDCCH usually requires the terminal to use different control channel elements CCE (Control Channel Element) aggregation levels (Aggregation Level), and/or different DCI formats (Format), and/or different DCIs on different time-frequency resources. The length, and/or different radio network temporary identifiers (Radio Network Temporary Identifier) perform blind detection, which requires a lot of power consumption. Data transmission using non-dynamic scheduling can reduce time delay, reduce signaling overhead, and reduce terminal power consumption.
以5G通信的新无线(New Radio,NR)技术为例,NR支持两类非动态调度数据传输,分别是非动态下行数据传输和非动态上行数据传输。非动态下行数据传输包括SPS下行数据传输,GF数据传输用于上行传输。非动态调度上行数据传输又可以称为免授权上行数据传输、免调度(scheduling-free)上行数据传输、无动态调度上行数据传输(uplink data transmission without dynamic scheduling)、无动态授权上行数据传输(uplink data transmission without dynamic grant)、配置授权的上行数据传输(uplink data transmission with configured grant)或高层配置的上行数据传输(uplink data transmission configured by high-layer)。上行数据传输包括PUSCH传输。Taking the New Radio (NR) technology of 5G communication as an example, NR supports two types of non-dynamic scheduled data transmission, namely non-dynamic downlink data transmission and non-dynamic uplink data transmission. Non-dynamic downlink data transmission includes SPS downlink data transmission, and GF data transmission is used for uplink transmission. Non-dynamic scheduling uplink data transmission can also be called authorization-free uplink data transmission, scheduling-free uplink data transmission, uplink data transmission without dynamic scheduling (uplink data transmission without dynamic scheduling), and uplink data transmission without dynamic authorization (uplink). data transmission without dynamic grant), uplink data transmission with configured authorization (uplink data transmission with configured grant), or uplink data transmission configured by high-layers (uplink data transmission configured by high-layer). Uplink data transmission includes PUSCH transmission.
GF上行数据传输包括基于第一类配置授权的PUSCH传输(Type 1 PUSCH transmission with a configured grant,或Type 1 configured grant PUSCH transmission)和基于第二类配置授权的PUSCH传输(Type 2 PUSCH transmission with a configured grant,或Type 2 configured grant PUSCH transmission)。GF uplink data transmission includes PUSCH transmission based on type 1 configuration authorization (Type 1 PUSCH transmission with a configured grant, or Type 1 configured grant PUSCH transmission) and PUSCH transmission based on type 2 configuration authorization (Type 2 PUSCH transmission with a configured grant, or Type 2 configured grant PUSCH transmission).
在第一类配置授权的PUSCH传输中,基站通过RRC信令向终端下发配置授权的配置(configured grant configuration,又可称为configuredGrantConfig),该configured grant configuration用于配置包括时域资源的周期、开环功控相关参数、波形、冗余版本序列、重复次数、跳频模式、资源分配类型、HARQ进程数、解调用参考信号(demodulation reference symbol,DMRS)相关参数、调制编码方案表格、资源块(resource block group,RBG)组大小、以及时域资源、频域资源、调制编码方式(modulation and coding scheme,MCS)等在内的全部传输资源和传输参数。终端接收到该configured grant configuration后,可立即使用其所配置的传输参数在配置的时频资源上进行PUSCH传输。In the PUSCH transmission of the first type of configuration authorization, the base station sends the configuration authorization configuration (configured grant configuration, also called configuredGrantConfig) to the terminal through RRC signaling. The configured grant configuration is used to configure the period, including time domain resources, Open-loop power control related parameters, waveform, redundancy version sequence, number of repetitions, frequency hopping mode, resource allocation type, HARQ process number, demodulation reference symbol (DMRS) related parameters, modulation and coding scheme table, resources Block (resource block group, RBG) group size, time domain resources, frequency domain resources, modulation and coding scheme (modulation and coding scheme, MCS) including all transmission resources and transmission parameters. After receiving the configured grant configuration, the terminal can immediately use its configured transmission parameters to perform PUSCH transmission on the configured time-frequency resources.
基于第二类配置授权的PUSCH传输中,采用两步的资源配置方式:首先,由configuredGrantConfig配置包括时域资源的周期、开环功控相关参数、波形、冗余版本序列、重复次数、跳频模式、资源分配类型、HARQ进程数、解调用参考信号相关参数、MCS表格、资源块RBG组大小等在内的传输资源和传输参数;然后由使用CS-小区无线网络临时标识符(radio network temporary identifier,RNTI)加扰的DCI激活第二类基于配置授权的PUSCH传输,并同时由该DCI配置包括时域资源、频域资源、DMRS、MCS等在内的其他传输参数。终端在接收到高层参数configuredGrantConfig时,不能立即使用该configuredGrantConfig所配置的资源和传输参数进行PUSCH传输,而必须等到接收到相应的激活DCI并配置其他资源和传输参数后,才能进行PUSCH传输。In the PUSCH transmission based on the second type of configuration authorization, a two-step resource configuration method is adopted: First, the configuredGrantConfig configuration includes the period of time domain resources, open-loop power control related parameters, waveforms, redundancy version sequence, number of repetitions, and frequency hopping. Mode, resource allocation type, HARQ process number, demodulation reference signal related parameters, MCS table, resource block RBG group size, etc., including transmission resources and transmission parameters; then use the CS-cell radio network temporary identifier (radio network) Temporary identifier (RNTI) scrambled DCI activates the second type of PUSCH transmission based on configuration authorization, and at the same time, the DCI configures other transmission parameters including time domain resources, frequency domain resources, DMRS, MCS, etc. When the terminal receives the high-level parameter configuredGrantConfig, it cannot immediately use the resources and transmission parameters configured by the configuredGrantConfig to perform PUSCH transmission, but must wait until the corresponding activated DCI is received and other resources and transmission parameters are configured before PUSCH transmission can be performed.
由于非动态调度数据传输的时频资源都是基站通过半静态方式配置的,相当于为终端预配置或预留的,即使终端没有上行数据传输需求,这些资源也是存在的。如图3所示,以非动态调度数据传输为GF上行数据传输为例,基站通过半静态方式配置的上行GF资源在时域上以周期性的方式重复出现,每个周期内的GF资源用于传输一个上行数据包。当终端在周期性的GF资源到来时,若有上行数据传输需求,就会在到来的GF资源上发送上行数据包。若上行数据传输需求是在某个周期(例如,图3中的周期1)内最后一个可用的GF资源之后产生的,就不得不等到下一个周期(例如,图3中的周期2)的GF资源。在这种情况下,导致数据传输的时延较长。Since the time-frequency resources for non-dynamically scheduled data transmission are all configured by the base station in a semi-static manner, which is equivalent to pre-configured or reserved for the terminal, these resources still exist even if the terminal has no uplink data transmission requirements. As shown in Figure 3, taking the non-dynamically scheduled data transmission as GF uplink data transmission as an example, the uplink GF resources configured by the base station in a semi-static manner recur in the time domain in a periodic manner, and the GF resources in each cycle are used To transmit an upstream data packet. When the terminal arrives on the periodic GF resource, if there is an uplink data transmission demand, it will send an uplink data packet on the arriving GF resource. If the uplink data transmission demand is generated after the last available GF resource in a certain period (for example, period 1 in Fig. 3), it has to wait until the GF of the next period (for example, period 2 in Fig. 3) Resources. In this case, the data transmission delay will be longer.
为支持多种对时延和可靠性有不同需求的业务,业界考虑在5G通信中支持在同一个带宽部分(Bandwidth Part)上允许有非动态调度数据传输的多套配置参数(例如,12套)。这种情况下,基站会为每一套配置参数建立索引(index)或标识(ID),并将索引或标识信息和其对应的配置参数下发给终端。在本申请的一实施例中,一套配置参数可以是指完成一次PUSCH传输或者PDSCH传输所需要的参数,例如,对于第一类配置授权的PUSCH传输而言,一套配置参数是指一个configuredGrantConfig中的全部参数,对于第二类配置授权的PUSCH传输而言,一套配置参数是指一个congfiguredGrantConfig中的全部参数,以及其对应的激活DCI所配置的参数。需要说明的是,用于第一类配置授权的PUSCH传输的configuredGrantConfig和用于第二类配置授权的PUSCH传输的configuredGrantConfig所包含的参数是不完全相同的,具体地可以参考标准3GPP TS38.331中的相关描述。In order to support a variety of services with different requirements for delay and reliability, the industry is considering supporting multiple sets of configuration parameters (for example, 12 sets) that allow non-dynamically scheduled data transmission on the same bandwidth part (Bandwidth Part) in 5G communications. ). In this case, the base station will create an index (index) or identification (ID) for each set of configuration parameters, and deliver the index or identification information and its corresponding configuration parameters to the terminal. In an embodiment of the present application, a set of configuration parameters may refer to parameters required to complete a PUSCH transmission or PDSCH transmission. For example, for the PUSCH transmission of the first type of configuration authorization, a set of configuration parameters refers to a configuredGrantConfig For all the parameters in the second type of configuration authorization PUSCH transmission, a set of configuration parameters refers to all the parameters in a congfiguredGrantConfig and the corresponding parameters configured to activate the DCI. It should be noted that the parameters included in the configuredGrantConfig used for PUSCH transmission of the first type of configuration authorization and the configuredGrantConfig used for the second type of configuration authorization of PUSCH transmission are not exactly the same. For details, please refer to the standard 3GPP TS38.331. Related description.
在本申请中,配置数据传输(上行数据传输和下行数据传输)是指配置用于数据传输的传输参数;激活数据传输是指激活数据传输的传输参数,使其可用于后续的数据传输;释放数据传输是指释放(去激活)数据传输的传输参数,使其处于失效(无效)状态而不可用于后续的数据传输。In this application, configuration data transmission (uplink data transmission and downlink data transmission) refers to configuration of transmission parameters used for data transmission; activation of data transmission refers to activation of transmission parameters of data transmission so that it can be used for subsequent data transmission; release Data transmission refers to the release (deactivation) of the transmission parameters of the data transmission so that it is in an invalid (invalid) state and cannot be used for subsequent data transmission.
以非动态调度数据传输为基于第二类配置授权的PUSCH传输为例,基站为终端配置多套基于第二类配置授权的PUSCH传输的传输参数时,基站需要激活每套传输参数。在一种激活方法(称之为单独激活)中,基站每次下发一个激活DCI,DCI携带一套传输参数的索引(或者标识),该索引所指示的那套传输参数被激活,若需要激活多套传输参数,则需要下发多个激活DCI,每个激活DCI需要携带被激活那套传输参数所对应的索引。在一种释放方法(称之为单独释放)中,若需要释放基于第二类配置授权的PUSCH传输的传输参数,基站每次下发一个释放DCI,释放DCI携带一套传输参数的索引(或者标识),该索引所指示的那套传输参数被释放,若需要释放多套传输参数,则需要下发多个释放DCI,每个激活DCI需要携带被释放那套传输参数所对应的索引。Taking the non-dynamically scheduled data transmission as the PUSCH transmission authorized based on the second type of configuration as an example, when the base station configures multiple sets of transmission parameters for the PUSCH transmission authorized based on the second type of configuration for the terminal, the base station needs to activate each set of transmission parameters. In an activation method (called separate activation), the base station issues an activated DCI each time, and the DCI carries a set of transmission parameter indexes (or identifiers), and the set of transmission parameters indicated by the index is activated, if necessary To activate multiple sets of transmission parameters, multiple activated DCIs need to be issued, and each activated DCI needs to carry the index corresponding to the activated set of transmission parameters. In a release method (called separate release), if the transmission parameters of PUSCH transmission authorized based on the second type of configuration need to be released, the base station issues a release DCI each time, and the release DCI carries a set of transmission parameter indexes (or ID), the set of transmission parameters indicated by the index is released. If multiple sets of transmission parameters need to be released, multiple release DCIs need to be issued, and each activated DCI needs to carry the index corresponding to the released set of transmission parameters.
在上述方法中,若需要激活或者释放多套参数,则需要基站发送多个DCI,因此,上述方法的信令开销很大。因而,提出了一种联合激活/释放方法。在联合激活方法中,基站可以配置一个激活状态集(每个状态集最多有,例如,16个状态值),该激活状态集包含一个或多个状态值,每个状态值对应(或关联)一个或多个索引(或标识),每个索引都对应一套基于第二类配置授权的PUSCH传输的传输参数,基站下发携带状态值的激活DCI,状态值所关联的索引所对应的传输参数为被激活的传输参数。在联合释放方法中,基站可以配置一个释放状态集(每个状态集最多有,例如,16个状态值),该激活状态集包含一个或多个状态值,每个状态值对应(或关联)一个或多个索引(或标识),每个索引都对应一套基于第二类配置授权的PUSCH传输的传输参数,基站下发携带状态值的释放DCI,状态值所关联的索引所对应的传输参数为被释放的传输参数。在上述方法中,一个DCI可以激活或者释放多套传输参数,从而可以节省信令开销。在本申请实施例中,激活状态集又可以被称之为激活组的索引集或者配置组的索引集,每个状态值也可以被称之为激活组的索引(或标识)或配置组的索引(或标识)。In the above method, if multiple sets of parameters need to be activated or released, the base station needs to send multiple DCIs. Therefore, the signaling overhead of the above method is large. Therefore, a joint activation/release method is proposed. In the joint activation method, the base station can configure an active state set (each state set has a maximum of, for example, 16 state values), the active state set contains one or more state values, and each state value corresponds (or is associated) One or more indexes (or identifiers), each index corresponds to a set of transmission parameters for PUSCH transmission authorized based on the second type of configuration, the base station issues the active DCI carrying the state value, and the transmission corresponding to the index associated with the state value The parameter is the activated transmission parameter. In the joint release method, the base station can configure a release state set (each state set has a maximum of, for example, 16 state values), the active state set contains one or more state values, and each state value corresponds (or is associated) One or more indexes (or identifiers), each index corresponds to a set of transmission parameters for PUSCH transmission authorized based on the second type of configuration, the base station issues the release DCI carrying the status value, and the transmission corresponding to the index associated with the status value The parameter is the released transmission parameter. In the above method, one DCI can activate or release multiple sets of transmission parameters, thereby saving signaling overhead. In the embodiments of the present application, the active state set can also be referred to as the index set of the active group or the index set of the configuration group, and each state value can also be referred to as the index (or identification) of the active group or the index set of the configuration group. Index (or identification).
上述单独激活/释放的方法虽然信令开销大,但是其具有很高的灵活性。上述联合激活/释放方法具有节省信令开销的优点,但是相比于单独激活/释放的方法,其灵活性不高。Although the above-mentioned separate activation/release method has high signaling overhead, it has high flexibility. The above-mentioned joint activation/release method has the advantage of saving signaling overhead, but its flexibility is not high compared to the single activation/release method.
进而,本申请实施例提供一种激活/释放非动态调度数据传输的方法,能够节省信令开销,还能兼顾有相对较高的灵活性。Furthermore, the embodiment of the present application provides a method for activating/releasing non-dynamic scheduling data transmission, which can save signaling overhead and also allows for relatively high flexibility.
网络设备通过高层信令(例如,RRC信令)为终端设备配置了多个非动态调度数据传输的传输配置,每个传输配置包含用于非动态调度数据传输的一组传输参数的配置信息。不同的传输配置可以是针对同一组传输参数的参数值的不同配置。在两个传输配置中,若只要有一个参数的参数值不同,那么该两个传输配置就可被认为不同的传输配置。例如,在传输配置1中,时域资源周期为5个时隙,在传输配置2中,时域资源周期为10个时隙,传输配置1和传输配置2中除了针对时域资源周期的配置不同外,其它参数的参数值均相同,在这种情况下,传输配置1和传输配置2就可以被认为是不同的传输配置。The network device configures multiple transmission configurations for non-dynamically scheduled data transmission for the terminal device through high-level signaling (for example, RRC signaling), and each transmission configuration includes configuration information of a set of transmission parameters for non-dynamically scheduled data transmission. Different transmission configurations may be different configurations of parameter values for the same set of transmission parameters. In the two transmission configurations, if only one parameter has a different parameter value, the two transmission configurations can be regarded as different transmission configurations. For example, in transmission configuration 1, the time domain resource period is 5 time slots, in transmission configuration 2, the time domain resource period is 10 time slots, transmission configuration 1 and transmission configuration 2 except for the configuration of time domain resource period Except for the difference, the parameter values of other parameters are the same. In this case, transmission configuration 1 and transmission configuration 2 can be regarded as different transmission configurations.
网络设备通过信令为终端配置激活状态集和/释放状态集。激活状态集至少包含一个状态值,每个状态值关联(或对应)一个或者多个传输配置。释放状态集至少包含一个状态值,每个状态值关联(或对应)一个或者多个传输配置。激活状态集合和释放状态集可以相同,也可以不同。若激活状态集和释放状态集相同,网路设备可以只需要配置一个状态集。激活状态集中的状态值和释放状态集中的值可以不同,也可以相同。激活状态集和释放状态集中相同的状态值所关联的传输配置可以相同,也可以不同。状态值关联传输配置,可以是状态值与传输配置的索引(标识或序号)相关联。The network device configures the activation state set and/the release state set for the terminal through signaling. The active state set contains at least one state value, and each state value is associated (or corresponding to) one or more transmission configurations. The release state set contains at least one state value, and each state value is associated with (or corresponds to) one or more transmission configurations. The activation state set and the release state set can be the same or different. If the activation state set and the release state set are the same, the network device may only need to configure one state set. The state value in the activation state set and the value in the release state set may be different or the same. The transmission configuration associated with the same state value in the activated state set and the released state set may be the same or different. The state value is associated with the transmission configuration, and the state value may be associated with the index (identification or sequence number) of the transmission configuration.
为便于理解,以网络设备为终端配置了12个传输配置(其索引分别为0-11为例),和包含4个状态值(状态值分别为0、1、2、3)的传输状态集为例,本申请给出了激活状态集中状态值与传输配置的索引的对应关系的一种示例,如表一所示。For ease of understanding, the network device is configured with 12 transmission configurations (the indexes are 0-11 as an example), and a transmission state set containing 4 state values (state values are 0, 1, 2, 3) As an example, this application provides an example of the corresponding relationship between the state value of the active state set and the index of the transmission configuration, as shown in Table 1.
表一、激活状态集中的状态值与传输配置的索引的对应关系Table 1. Correspondence between the state value in the active state set and the index of the transmission configuration
需要说明的是,上述表格的举例仅是为了便于理解本申请提供的方案,不应理解为对申请的限定。It should be noted that the examples of the above tables are only for the convenience of understanding the solutions provided in this application, and should not be construed as limiting the application.
网络设备可以通过RRC信令为终端设备配置激活状态集。以非动态调度数据传输为基于第二类配置授权的PUSCH传输,一个传输配置为包括一个第二类配置授权的PUSCH传输的configuredGrantConfig所包含的参数的配置信息为例,本申请提供了一种在RRC信令中用于配置上述状态集的信息结构,如下文所述:The network device can configure the active state set for the terminal device through RRC signaling. Taking the non-dynamically scheduled data transmission as the PUSCH transmission based on the second type of configuration authorization, and a transmission configuration including the configuration information of the parameters included in the configuredGrantConfig of the second type of configuration authorization PUSCH transmission as an example, this application provides a The information structure used to configure the above state set in RRC signaling is as follows:
其中,Type2Configuredgrantconfig-ActivateStateList表示网络设备配置的激活状态集,包含最多16个状态。Type2Configuredgrantconfig-ActivateState表示激活状态集中的某个状态,stateValue为该状态的值,取值范围为0到15,type2-CGConfig包含一个或多个索引值ConfiguredGrantConfigIndex,表示该状态所关联的索引值,每个索引值对应一个传输配置。可以理解的是,除了上述信息结构外,还可以有其它信息结构也可以实现对激活状态 机的配置,本申请不做限制。Among them, Type2Configuredgrantconfig-ActivateStateList represents the activation state set of the network device configuration, including a maximum of 16 states. Type2Configuredgrantconfig-ActivateState represents a state in the activated state set, stateValue is the value of the state, and the value range is 0 to 15, type2-CGConfig contains one or more index values ConfiguredGrantConfigIndex, which represents the index value associated with the state, each The index value corresponds to a transmission configuration. It is understandable that in addition to the above information structure, there may be other information structures that can also implement the configuration of the activation state machine, which is not limited in this application.
配置释放状态集的方法和配置激活状态集的方法相同,只需要将“激活状态(或ActivateState)”替换成“释放状态(或ReleaseState)”即可,此处不再赘述。The method of configuring the release state set is the same as the method of configuring the activation state set. You only need to replace the "activation state (or ActivateState)" with the "release state (or ReleaseState)", which will not be repeated here.
可以理解的是,除了可以由网络设备通过信令为终端配置释放状态集和释放状态集的方式外,终端设备可以有其它的方式获得释放状态集和释放状态集。例如,由终端设备根据预设的规则确定各个状态值所对应的传输配置,在此情况下,网络设备也是根据相同的预设规则确定各个状态值所对应的传输配置,该预设的规则可以是由标准协议规定的,也可以是网络设备与终端设备之间相互协商得到的。It is understandable that, in addition to the manner in which the network device can configure the release state set and the release state set for the terminal through signaling, the terminal device may obtain the release state set and the release state set in other ways. For example, the terminal device determines the transmission configuration corresponding to each state value according to a preset rule. In this case, the network device also determines the transmission configuration corresponding to each state value according to the same preset rule. The preset rule may It is specified by a standard protocol, or it can be negotiated between the network device and the terminal device.
如图4所示,本申请实施例提供的一种激活非动态调度数据传输的方法的流程如下所述。该方法的执行主体以终端和网络设备为例,该方法中的非动态调度数据传输以基于第二类配置授权的PUSCH传输为例。As shown in FIG. 4, the process of a method for activating non-dynamic scheduling data transmission provided by an embodiment of the present application is as follows. The execution body of this method takes terminals and network devices as examples, and the non-dynamic scheduling data transmission in this method takes PUSCH transmission authorized based on the second type of configuration as an example.
S401、终端接收网络设备发送的用于激活非动态调度数据传输的DCI。S401: The terminal receives the DCI sent by the network device for activating non-dynamic scheduling data transmission.
若终端设备收到的DCI满足预设条件时,该DCI为用于激活基于第二类配置授权的PUSCH传输。该预设条件由标准规定的,用于判断DCI是否是用于实现激活功能的DCI。If the DCI received by the terminal device meets the preset condition, the DCI is used to activate PUSCH transmission based on the second type of configuration authorization.

The terminal parses each domain (field) in the DCI according to the structure of the DCI as the activation function.
对于基于配置授权的PUSCH传输,可以用作激活基于配置授权的PUSCH传输的DCI格式可以是DCI format 0_0和0_1,还可以是其他新设计的format。For PUSCH transmission based on configuration authorization, the DCI format that can be used to activate PUSCH transmission based on configuration authorization can be DCI format 0_0 and 0_1, or other newly designed formats.

S402、将所述DCI中的X个比特确定为激活指示域,所述激活指示域指示被激活的传输配置,其中,X是根据激活状态集中的最大状态值确定的,激活状态集中的每个状态值对应多个传输配置中的一个或者多个传输配置,每个传输配置包括用于非动态调度数据传输的一组传输参数的配置信息。S402.

在本实施例中,激活指示域可以直接指示被激活的传输配置的索引,也可以指示激活状态集中的一个状态值,通过指示该状态值来间接指示该状态值所对应的传输配置,该状态值所对应的传输配置即为被激活的传输配置。In this embodiment, the activation indication field can directly indicate the index of the activated transmission configuration, or it can indicate a state value in the activation state set. By indicating the state value, it indirectly indicates the transmission configuration corresponding to the state value. The transmission configuration corresponding to the value is the activated transmission configuration.

在另一实施例中,
其中,P为一个BWP上传输配置的数量。在另一实施例中,
In another embodiment, Where, P is the number of transmission configurations on a BWP. In another embodiment,
若确定出来的X=0,表示该DCI中不存在激活指示域,此情况下,意味着网络设备只给终端设备配置了一个传输配置,或者网络设备为终端激活全部的传输配置。If X=0 is determined, it means that there is no activation indication field in the DCI. In this case, it means that the network device only configures one transmission configuration for the terminal device, or the network device activates all transmission configurations for the terminal.
在一实施例中,Q具体为激活BWP对应的激活状态集中的最大状态值。在另一实施例中,Q具体为终端的多个BWP对应的激活状态集中的最大状态值。例如,Q=max{Q

1,…P
N},其中,P
j(j=1,…N)为第j个BWP上的传输配置的数量,N为终端有传输配置的BWP的总数量。
In an embodiment, P is specifically the number of transmission configurations corresponding to the activated BWP. In another embodiment, P is specifically the largest number among the number of transmission configurations on multiple BWPs of the terminal. For example, P=max{P 1 ,...P N }, where P j (j=1,...N) is the number of transmission configurations on the j-th BWP, and N is the total number of BWPs with transmission configurations on the terminal.
在一实施例中,P和Q分别为同一BWP上的传输配置的数量和激活状态集中的最大状态值。In an embodiment, P and Q are respectively the number of transmission configurations on the same BWP and the maximum state value in the active state set.
终端设备可以从预设的比特开始的X个比特确定为激活指示域。可以根据所述DCI的格式确定所述预设的比特。The terminal device may determine X bits starting from the preset bit as the activation indication field. The preset bit may be determined according to the format of the DCI.
激活指示激活域可以是一个域,也可以由多个域组合而成;可以是前文所述DCI格式中已经存在的域,例如HARQ进程数(HARQ Process Number,HPN)域,冗余版本RV域,发送功率控制(transmit power control,TPC)域等,也可以是不同于DCI中已经存在的任何域的新引入的域。例如,若HPN域的比特数量大于或等于X,将HPN域的前X个比特作为激活指示域,若HPN域的比特数量小于X,可以将HPN域的全部比特作为激活指示激活域的一部分比特,然后将其它域的比特为所述激活指示激活域的剩下的比特。Activation indication The activation field can be a single field or a combination of multiple fields; it can be a field that already exists in the DCI format described above, such as HARQ Process Number (HPN) field, redundancy version RV field , The transmit power control (TPC) domain, etc., may also be a newly introduced domain that is different from any domain that already exists in the DCI. For example, if the number of bits in the HPN field is greater than or equal to X, the first X bits of the HPN field are used as the activation indication field. If the number of bits in the HPN field is less than X, all bits in the HPN field can be used as part of the activation indication active field. , And then use the bits of the other fields as the remaining bits of the active field of the activation indication.
S403、根据所述激活指示域,确定被激活的传输配置。S403: Determine the activated transmission configuration according to the activation indication field.
在一实施例中,步骤S403包括:在所述激活指示域的值与激活状态集中的一个状态值相同的情况下,确定所述状态值所对应的所有传输配置为被激活的传输配置。在本实施例中,只要所述激活指示域的值与激活状态集中的任意一个状态值相同,终端就认为该激活指示域的值是激活状态集中的一个状态值。所述激活指示域的值只与传输配置的索引相同时,而与激活状态集中的所述状态值均不相同,终端才认为该激活指示域的值指示的是一个传输配置的索引。终端不期望激活指示域所指示的值既不同于任何一个传输配置的所索引、也不同于激活状态集中的任何状态值,或者当出现指示域所指示的值既不同于任何一个传输配置的索引、也不同于激活状态集中的任何状态值的情形时,终端认为这是一个错误情形(error case),该DCI不激活任何传输配置。以表一所示的激活状态集中的状态值与传输配置的索引的对应关系为例,若激活指示域的值为0-3中的一个值时,本实施例的指示域指示的就是激活状态指示集中的状态值;若激活指示域的值为4-11中的一个值时,本实施例的指示域指示的就是一个传输配置的索引。在本实施例中,与激活状态集中的状态值相同的索引对应的传输配置是无法被单独激活的,与激活状态集中的状态值不相同的索引对应的传输配置是可以被单独激活的。In an embodiment, step S403 includes: when the value of the activation indication field is the same as a state value in the activation state set, determining that all transmission configurations corresponding to the state value are activated transmission configurations. In this embodiment, as long as the value of the activation indication field is the same as any state value in the activation state set, the terminal considers the value of the activation indication field to be a state value in the activation state set. When the value of the activation indication field is only the same as the index of the transmission configuration, but is not the same as the state value in the activation state set, the terminal considers that the value of the activation indication field indicates an index of a transmission configuration. The terminal does not expect that the value indicated by the activation indication field is different from the index of any transmission configuration, and is also different from any state value in the activation state set, or when the value indicated by the indication field is different from the index of any transmission configuration When it is also different from the situation of any state value in the activated state set, the terminal considers this to be an error case, and the DCI does not activate any transmission configuration. Taking the corresponding relationship between the state value in the activation state set and the index of the transmission configuration shown in Table 1 as an example, if the value of the activation indication field is a value from 0 to 3, the indication field in this embodiment indicates the activation state. State value in the indication set; if the value of the activation indication field is one of 4-11, the indication field in this embodiment indicates an index of a transmission configuration. In this embodiment, the transmission configuration corresponding to the index with the same state value in the activation state set cannot be individually activated, and the transmission configuration corresponding to the index with the different state value in the activation state set can be activated separately.
在一实施例中,步骤S403包括:在所述激活指示域的值与一个传输配置的索引相同的情况下,确定所述索引所对应的传输配置为被激活的传输配置。在本实施例中,只要所述激活指示域的值与任意一个传输配置的索引相同,终端就认为该激活指示域的值是一个传输配置的索引。所述激活指示域的值只与激活状态集中的状态值相同时,而与任意一个传输配置的索引均不相同时,终端才认为该激活指示域的值指示的是激活状态集中的一个状态值。终端不期望激活指示域所指示的值既不同于任何一个传输配置的所索引、也不同于激活状态集中的任何状态值,或者当出现指示域所指示的值既不同于任何一个传输配置的索引、也不同于激活状态集中的任何状态值的情形时,终端认为这是一个错误情形(error case),该DCI不激活任何传输配置。以表一所示的激活状态集中的状态值与传输配置的索引的对应关系为例,若激活指示域的值为0-11中的一个值时,本实施例的指示域指示的就是一个传输配置的索引;在本实施例中,即使激活指示域的值为0-3中的一个值时,本实施例的指示域也不认为是指示激活状态集中的状态值,此情况相当于联合激活被禁用。若激活状态集中只有部分状态值与传输配置的索引相同时,只有该部分状态值对应的联合激活被禁用,其它状态值还是可以被指示,从而实现联合激活。本申请实施例的DCI的激活指示域大小不是固定不变的,其与激活状态集中的最大状态值有关,因此,本申请实施例提供的方法可以节省用于指示激活的传输配置的信令开销。In an embodiment, step S403 includes: when the value of the activation indication field is the same as the index of a transmission configuration, determining that the transmission configuration corresponding to the index is the activated transmission configuration. In this embodiment, as long as the value of the activation indication field is the same as the index of any transmission configuration, the terminal considers the value of the activation indication field to be an index of a transmission configuration. When the value of the activation indication field is only the same as the state value in the activation state set, but is not the same as the index of any transmission configuration, the terminal considers that the value of the activation indication field indicates a state value in the activation state set. . The terminal does not expect that the value indicated by the activation indication field is different from the index of any transmission configuration, and is also different from any state value in the activation state set, or when the value indicated by the indication field is different from the index of any transmission configuration When it is also different from any state value in the activated state set, the terminal considers this to be an error case, and the DCI does not activate any transmission configuration. Taking the corresponding relationship between the state value in the activation state set and the index of the transmission configuration shown in Table 1 as an example, if the value of the activation indication field is a value from 0 to 11, the indication field in this embodiment indicates a transmission Configuration index; in this embodiment, even when the value of the activation indication field is one of 0-3, the indication field in this embodiment is not considered to indicate the state value in the activation state set. This situation is equivalent to joint activation Disabled. If only part of the state values in the activation state set are the same as the index of the transmission configuration, only the joint activation corresponding to this part of the state value is disabled, and other state values can still be indicated, thereby realizing joint activation. The size of the DCI activation indication field in the embodiment of this application is not fixed, and is related to the maximum state value in the activation state set. Therefore, the method provided in the embodiment of this application can save signaling overhead for indicating activation of the transmission configuration. .
如图5所示,本申请实施例提供的一种释放非动态调度数据传输的方法的流程如下所述。该方法的执行主体以终端和网络设备为例,该方法中的非动态调度数据传输以基于第二类配置授权的PUSCH传输为例。As shown in FIG. 5, the flow of a method for releasing non-dynamic scheduling data transmission provided by an embodiment of the present application is as follows.

若终端设备收到的DCI满足预设条件时,该DCI为用于释放基于第二类配置授权的PUSCH传输。该预设条件由标准规定的,用于判断DCI是否是用于实现释放功能的DCI。If the DCI received by the terminal device meets the preset condition, the DCI is used to release the PUSCH transmission authorized based on the second type of configuration. The preset condition is specified by the standard, and is used to determine whether the DCI is the DCI used to realize the release function.

3、DCI中的冗余版本(redundancy version,RV)域设置成0;3. The redundancy version (RV) field in DCI is set to 0;
4、MCS域和频域资源分配(Frequency Domain Resource Assignment,FDRA)设置成全1。4. MCS domain and frequency domain resource assignment (Frequency Domain Resource Assignment, FDRA) are set to all 1.
当接收到的DCI满足上述四个条件时,那么该DCI即为用于释放基于第二类配置授权的PUSCH传输的DCI。终端根据作为释放功能的DCI的结构来解析该DCI中的各个域(字段)。When the received DCI meets the above four conditions, the DCI is the DCI used to release the PUSCH transmission authorized based on the second type of configuration. The terminal parses each domain (field) in the DCI according to the structure of the DCI as the release function.

The transmission configuration corresponding to the value is the released transmission configuration.

在另一实施例中,
其中,P为一个BWP上传输配置的数量。另一实施例中,
In another embodiment, Among them, P is the number of transmission configurations on a BWP. In another embodiment,
若确定出来的X=0,表示该DCI中不存在释放指示域,此情况下,意味着网络设备只给终端设备配置了一个传输配置,或者网络设备为终端释放全部的传输配置。If X=0 is determined, it means that there is no release indication field in the DCI. In this case, it means that the network device only configures one transmission configuration for the terminal device, or the network device releases all transmission configurations for the terminal.
在一实施例中,Q具体为激活BWP对应的释放状态集中的最大状态值。在另一实施例中,Q具体为终端的多个BWP对应的释放状态集中的最大状态值。例如,Q=max{Q
1,…Q
M},其中,Q
i(i=1,…M)为第i个BWP对应的状态集中的最大状态值,M为终端的配置有释放状态集的BWP的总数量。
In an embodiment, Q is specifically the maximum state value in the release state set corresponding to the activated BWP.

在一实施例中,P和Q分别为同一BWP上的传输配置的数量和释放状态集中的最大状态值。In an embodiment, P and Q are respectively the number of transmission configurations on the same BWP and the maximum state value in the release state set.
终端设备可以从预设的比特开始的X个比特确定为释放指示域。可以根据所述DCI的格式确定所述预设的比特。The terminal device may determine X bits starting from the preset bit as the release indication field. The preset bit may be determined according to the format of the DCI.
释放指示释放域可以是一个域,也可以由多个域组合而成;可以是前文所述DCI格式中已经存在的域,例如HARQ进程数(HARQ Process Number,HPN)域,冗余版本RV域,发送功率控制(transmit power control,TPC)域等,也可以是不同于DCI中已经存在的任何域的新引入的域。例如,若HPN域的比特数量大于或等于X,将HPN域的前X个比特或后X个比特作为释放指示域,若HPN域的比特数量小于X,可以将HPN域的全部比特作为释放指示释放域的一部分比特,然后将其它域的比特为所述释放指示释放域的剩下的比特。Release indication The release field can be one field or a combination of multiple fields; it can be a field that already exists in the DCI format described above, such as HARQ Process Number (HPN) field, redundancy version RV field , The transmit power control (TPC) domain, etc., may also be a newly introduced domain that is different from any domain that already exists in the DCI. For example, if the number of bits in the HPN field is greater than or equal to X, the first X bits or the last X bits of the HPN field are used as the release indication field. If the number of bits in the HPN field is less than X, all bits in the HPN field can be used as the release indication Part of the bits of the field is released, and then the bits of other fields are used as the release instruction to release the remaining bits of the field.
S503、根据所述释放指示域,确定被释放的传输配置。S503: Determine the released transmission configuration according to the release indication field.
在一实施例中,步骤S403包括:在所述释放指示域的值与释放状态集中的一个状态值相同的情况下,确定所述状态值所对应的所有传输配置为被释放的传输配置。在本实施例中,只要所述释放指示域的值与释放状态集中的任意一个状态值相同,终端就认为该释放指示域的值是释放状态集中的一个状态值。所述释放指示域的值只与传输配置的索引相同时,而与释放状态集中的所述状态值均不相同,终端才认为该释放指示域的值指示的是一个传输配置的索引。终端不期望释放指示域所指示的值既不同于任何一个传输配置的所索引、也不同于释放状态集中的任何状态值,或者当出现指示域所指示的值既不同于任何一个传输配置的索引、也不同于释放状态集中的任何状态值的情形时,终端认为这是一个错误情形(error case),该DCI不释放任何传输配置。以表一所示的释放状态集中的状态值与传输配置的索引的对应关系为例,若释放指示域的值为0-3中的一个值时,本实施例的指示域指示的就是释放状态指示集中的状态值;若释放指示域的值为4-11中的一个值时,本实施例的指示域指示的就是一个传输配置的索引。在本实施例中,与释放状态集中的状态值相同的索引对应的传输配置是无法被单独释放的,与释放状态集中的状态值不相同的索引对应的传输配置是可以被单独释放的。In an embodiment, step S403 includes: when the value of the release indication field is the same as a state value in the release state set, determining that all transmission configurations corresponding to the state value are released transmission configurations. In this embodiment, as long as the value of the release indication field is the same as any state value in the release state set, the terminal considers the value of the release indication field to be a state value in the release state set. When the value of the release indication field is only the same as the index of the transmission configuration, but is different from the state value in the release state set, the terminal considers that the value of the release indication field indicates an index of a transmission configuration. The terminal does not expect that the value indicated by the release indication field is different from the index of any transmission configuration, and is also different from any state value in the release state set, or when the value indicated by the indication field is different from the index of any transmission configuration , Also different from the situation where any state value in the state set is released, the terminal considers this to be an error case, and the DCI does not release any transmission configuration. Taking the corresponding relationship between the state value in the release state set and the index of the transmission configuration shown in Table 1 as an example, if the value of the release indication field is a value from 0 to 3, the indication field in this embodiment indicates the release state State value in the indication set; if the value of the release indication field is one of 4-11, the indication field in this embodiment indicates an index of a transmission configuration. In this embodiment, the transmission configuration corresponding to the index with the same state value in the release state set cannot be released separately, and the transmission configuration corresponding to the index with the different state value in the release state set can be released separately.
在一实施例中,步骤S503包括:在所述释放指示域的值与一个传输配置的索引相同的情况下,确定所述索引所对应的传输配置为被释放的传输配置。在本实施例中,只要所述释放指示域的值与任意一个传输配置的索引相同,终端就认为该释放指示域的值是一个 传输配置的索引。所述释放指示域的值只与释放状态集中的状态值相同时,而与任意一个传输配置的索引均不相同时,终端才认为该释放指示域的值指示的是释放状态集中的一个状态值。终端不期望释放指示域所指示的值既不同于任何一个传输配置的所索引、也不同于释放状态集中的任何状态值,或者当出现指示域所指示的值既不同于任何一个传输配置的索引、也不同于释放状态集中的任何状态值的情形时,终端认为这是一个错误情形(error case),该DCI不释放任何传输配置。以表一所示的释放状态集中的状态值与传输配置的索引的对应关系为例,若释放指示域的值为0-11中的一个值时,本实施例的指示域指示的就是一个传输配置的索引;在本实施例中,即使释放指示域的值为0-3中的一个值时,本实施例的指示域也不认为是指示释放状态集中的状态值,此情况相当于联合释放被禁用。若释放状态集中只有部分状态值与传输配置的索引相同时,只有该部分状态值对应的联合释放被禁用,其它状态值还是可以被指示,从而实现联合释放。In an embodiment, step S503 includes: when the value of the release indication field is the same as the index of a transmission configuration, determining that the transmission configuration corresponding to the index is the released transmission configuration. In this embodiment, as long as the value of the release indication field is the same as the index of any transmission configuration, the terminal considers the value of the release indication field to be an index of a transmission configuration. When the value of the release indication field is only the same as the state value in the release state set, but is not the same as the index of any transmission configuration, the terminal considers that the value of the release indication field indicates a state value in the release state set. . The terminal does not expect that the value indicated by the release indication field is different from the index of any transmission configuration, and is also different from any state value in the release state set, or when the value indicated by the indication field is different from the index of any transmission configuration , Also different from the situation where any state value in the state set is released, the terminal considers this to be an error case, and the DCI does not release any transmission configuration. Taking the corresponding relationship between the state value in the release state set and the index of the transmission configuration shown in Table 1 as an example, if the value of the release indication field is a value from 0 to 11, the indication field in this embodiment indicates a transmission Configuration index; in this embodiment, even when the value of the release indication field is one of 0-3, the indication field in this embodiment is not considered to be the state value in the release state set, which is equivalent to joint release Disabled. If only part of the state value in the release state set is the same as the index of the transmission configuration, only the joint release corresponding to this part of the state value is disabled, and other state values can still be indicated, thereby realizing the joint release.
本申请实施例的DCI的释放指示域大小不是固定不变的,其与释放状态集中的最大状态值有关,因此,本申请实施例提供的方法可以节省用于指示释放的传输配置的信令开销。The size of the DCI release indication field in the embodiment of this application is not fixed, and is related to the maximum state value in the release state set. Therefore, the method provided in the embodiment of this application can save the signaling overhead of the transmission configuration for indicating the release. .
