为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施方式作进一步地详细描述。
首先,对本申请实施例中涉及的名词进行简单介绍:
1、NR中的SS(Synchronization Signal,同步信号)/PBCH(Physical Broadcast Channel,物理广播信道)block(块):
在NR系统中的公共信道和信号,如同步信号和广播信道,需要通过多波束扫描的方式覆盖整个小区,便于小区内的UE接收。同步信号的多波束发送是通过定义SS/PBCH burst set(突发集合)实现的。一个SS/PBCH burst set包含一个或多个SS/PBCH block。一个SS/PBCH block用于承载一个波束的同步信号和广播信道。因此,一个SS/PBCH burst set可以包含小区内L个波束的同步信号。并且L与系统的频段有关:
频率在3吉赫兹以内,L为4;
频率在3吉赫兹到6吉赫兹之间,L为8;
频率在6吉赫兹到52.6吉赫兹之间,L为64。
例如,如图1所示,一个SSB(Synchronization Signal Block,同步信号块)中包含一个符号的PSS(Primary Synchronization Signal,主同步信号),一个符号的SSS(Secondary Synchronization Signal,辅同步信号)和两个符号的PBCH(Physical broadcast channel,物理广播信道)。其中,PBCH所占的时域资源和频域资源中,包含DMRS(Demodulation Reference Signal,解调参考信息),DMRS解调参数用于PBCH(Physical Broadcast Channel,物理广播信道)的解调。
另外,SS/PBCH burst set内所有的SS/PBCH block在5ms的时间窗内发送,并以一定的周期重复发送。
在一种可能实现方式中,周期通过高层参数SSB-timing进行配置。
其中,周期可以为5ms,10ms,20ms,40ms,80ms,160ms等。
终端设备通过接收到的SSB得到该SSB的标签,SSB的标签的取值范围为[0,L-1],L为SSB所在频段对应的SSB的最大个数。SSB标签对应该SSB在5ms时间窗内的相对位置,终端根据该SSB的标签和PBCH中承载的半帧指示,进行帧同步。其中,SS/PBCH block的标签通过PBCH的DMRS或者PBCH承载的信息来指示。
除了同步信号和PBCH需要进行多波束扫描,其他的一些公共信息,如SIB1(System Information Block 1,系统信息块1),寻呼(paging),也需要通过多波束扫描的方式发送。
2、RACH(Random Access Channel,随机接入信道)过程:
在NR技术中,定义了为终端设备配置的PRACH资源,并且为终端设备配置了256种方式。
另外,每一种PRACH资源配置的信息包括前导码格式、周期、无线帧偏移、无线帧内的子帧编号、子帧内的起始符号、子帧内PRACH时隙的个数、PRACH时隙内PRACH资源的个数、PRACH资源持续时长中的至少一项。
终端设备接收到指示PRACH资源配置的信息后,可以确定PRACH资源的时域资源、频域资源、前导码等信息。
例如,如表1所示,对于一个PRACH的配置信息,可以表示前导码格式、PRACH资源所在的无线帧、子帧、起始符号、持续时长等等。
表1
并且,PRACH资源的频域资源位置通过高层信令指示。其中,该高层信令中包括偏移值和PRACH资源在频域上的个数。
例如,该高层信令为RACH-ConfigGeneric,包括参数msg1-FrequencyStart(频率起始)和msg1-FDM(Frequency Division Multiplexing,频分多路复用),其中,msg1-FrequencyStart用于指示确定PRACH资源0的RB(Resource Block,资源块)的起始位置相对于上行公共BWP(Band Width Part,带宽部分)的频域起始位置的偏移,可以确定PRACH资源的频域起始位置,msg1-FDM用于指示PRACH资源在频域上的个数,并且PRACH在业务信道上占用的RB数由prach-RootSequenceIndex(一种序列指数)指示前导码序列,其PRACH频域位置如图2所示,其中,msg1-FDM=8。
另外,终端设备在系统消息指示的PRACH资源配置的基础上,还指示了SSB与PRACH资源的映射方式,终端设备根据SSB和该映射方式,确定可以使用的PRACH资源。
其中,每个SSB关联有至少一个PRACH资源,且关联有多个基于竞争的前导码。
网络设备为终端设备配置N个SSB关联的一个PRACH资源,以及每个SSB在每个PRACH资源上基于竞争的前导码数量。
当N小于1时,一个SSB映射到1/N个连续的PRACH。例如,当N为1/4时,一个SSB映射4个PRACH资源,且有R个连续的前导码映射到SSB。
当N不小于1时,R个连续的前导码映射到SSB,且每个PRACH资源从前导码的索引开始。例如,当N为2时,两个SSB映射一个PRACH资源,SSB0的前导码索引从0开始,前导码索引为0-31,而SSB 1的前导码索引从32开始,前导码索引为32-63。
另外,SSB到PRACH资源的映射遵循的原则为:
1、在一个PRACH资源中,前导码索引的顺序为递增;
2、频率复用的PRACH资源的频率资源索引的顺序为递增;
3、在PRACH时隙内,时域复用的PRACH资源的时域资源索引的顺序为递增;
4、PRACH时隙索引的顺序为递增。
例如,当SSB的数量为8,PRACH资源在频域上的数量为4,一个SSB映射到1/4个PRACH资源,则SSB与PRACH资源的映射关系如图3所示。
图4示出了本申请一个示例性实施例提供的通信系统的框图,该通信系统可以包括:接入网12和终端设备13。
接入网12中包括若干个网络设备120。网络设备120可以是基站,基站是一种部署在接入网12中用以为终端设备提供无线通信功能的装置。基站可以包括各种形式的宏基站,微基站,中继站,接入点等等。在采用不同的无线接入技术的系统中,具备基站功能的设备的名称可能会有所不同,例如在LTE系统中,称为eNodeB或者eNB;在5G NR-U系统中,称为gNodeB或者gNB。随着通信技术的演进,“基站”这一描述可能会变化。为方便本申请实施例中,上述为终端设备13提供无线通信功能的装置统称为接入网设备。
终端设备13可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备,以及各种形式的用户设备,移动台(Mobile Station,MS),终端设备(terminal device)等等。为方便描述,上面提到的设备统称为终端设备。接入网设备120与终端设备13之间通过某种空口技术互相通信,例如Uu接口。
本申请实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)系统、先进的长期演进(Advanced long term evolution,LTE-A)系统、新无线(New Radio,NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to unlicensed spectrum,LTE-U)系统、NR-U系统、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信系统、无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)、下一代通信系统或其他通信系统等。
通常来说,传统的通信系统支持的连接数有限,也易于实现,然而,随着通信技术的发展,移动通信系统将不仅支持传统的通信,还将支持例如,设备到设备(Device to Device,D2D)通信,机器到机器(Machine to Machine,M2M)通信,机器类型通信(Machine Type Communication,MTC),车辆间(Vehicle to Vehicle,V2V)通信以及车联网(Vehicle to everything,V2X)系统等。本申请实施例也可以应用于这些通信系统。
图5示出了本申请一个示例性实施例提供的资源确定方法的流程图,应用于如图4所示的终端设备和网络设备中,该方法包括以下内容中的至少部分内容:
步骤501,网络设备向终端设备发送第一配置信息。
步骤502,终端设备接收第一配置信息。
其中,该第一配置信息用于配置确定第一SSB对应的PRACH资源。
可选地,该PRACH资源可以为PRACH时机。
在一种可能实现方式中,该第一配置信息携带在信令中,网络设备通过发送信令的方式,将第一配置信息发送给终端设备。
步骤503,终端设备根据第一配置信息中的配置参数,确定SSB与PRACH资源的映射方式。
终端设备接收到该第一配置信息后,即可根据该第一配置信息,确定SSB与PRACH资源的映射方式。
其中,该第一配置信息可以包括以下至少一项:
每个PRACH资源映射的SSB的第一数量;
SSB的第二数量;
PRACH资源的第三数量。
其中,该第一数量用于确定每个PRACH资源映射的SSB的数量。例如,当该第一数量为1/4时,则说明4个PRACH资源映射一个SSB。而当该第一数量为2时,则说明1个PRACH资源映射两个SSB。
另外,该第一数量可以采用参数ssb-perRACH-Occasion指示。
该第二数量用于确定每次映射的SSB的数量。例如,该第二数量为4,则在每次映射时,包括4个SSB,这4个SSB的标签可以为0-3。而当第二数量为8时,则在每次映射时,包括8个SSB,这8个SSB的标签可以为0-7。
另外,该第二数量可以采用SIB1或者ServingCellConfigCommon信令中的ssb-PositionsInBurst指示。
该第三数量用于确定在映射过程中PRACH资源的数量。
在一种可能实现方式中,该第三数量用于确定当时域资源相同时,频域资源上包括的PRACH资源的数量。
另外,该第三数量可以采用参数msg1-FDM指示。
例如,当该第三数量为4时,则表示在频域资源上包括4个PRACH资源。而当第三数量为2时,则表示在频域资源上包括2个PRACH资源。
在另一种可能实现方式中,该第三数量用于确定在一次映射中,包括的PRACH资源的总数量。
例如,当第三数量为16时,则表示在一次映射中,包括16个PRACH资源。
其中,SSB与PRACH资源的映射方式包括第一映射方式和第二映射方式。
在一种可能实现方式中,该第一映射方式为按照PRACH资源的频域资源的排列顺序,再按照PRACH资源的时域资源的排列顺序,对SSB与对应的PRACH资源进行映射。
按照PRACH资源的频域资源的排列顺序,将SSB依次映射到PRACH资源上,然后再按照PRACH资源的时域资源的排列顺序,将SSB依次映射到PRACH资源上,当每个SSB均与对应的PRACH资源映射时,完成一次映射。
例如,当第一配置信息中包括的msg1-FDM=4,ssb-perRACH-Occasion=1/4,SSB的数量为8时,则确定1个SSB与4个PRACH资源映射,且在频域上PRACH资源的数量为4个,则先按照PRACH资源的频域资源的排列顺序,再按照PRACH资源的时域资源的排列顺序,对SSB与对应的PRACH资源进行映射,得到如图3所示的SSB与PRACH资源的映射关系图。
或者,当第一配置信息中msg1-FDM=4,ssb-perRACH-Occasion=2,SSB的数量为8时,确定2个SSB与1个PRACH资源映射,且在频域上PRACH资源的数量为4个,则先按照PRACH资源的频域资源的排列顺序,再按照PRACH资源的时域资源的排列顺序,对SSB与对应的PRACH资源进行映射,得到如图6所示的SSB与PRACH资源的映射关系图。
或者,而当msg1-FDM=4,ssb-perRACH-Occasion=2,SSB的数量为4时,确定2个SSB与1个PRACH资源映射,且在频域上PRACH资源的数量为4个,则先按照PRACH资源的频域资源的排列顺序,再按照PRACH资源的时域资源的排列顺序,对SSB与对应的PRACH资源进行映射,得到如图7所示的SSB与PRACH资源的映射关系图。
可选地,终端设备按照SSB的标签从小到大的顺序,且按照PRACH资源的频域资源从小到大的顺序,再按照PRACH资源的时域资源从小到大的顺序,可以依次确定SSB对应的PRACH资源。
例如,当SSB的标签为0-7时,则先对标签为0的SSB进行映射,再对标签为1的SSB进行映射,以此类推,直到对标签为7的SSB进行映射,即可确定标签为0-7的SSB对应的PRACH资源。
在另一种可能实现方式中,该第二映射方式为按照PRACH资源的时域资源的排列顺序,再按照PRACH资源的频域资源的排列顺序,对SSB与对应的PRACH资源进行映射。
先按照PRACH资源的时域资源的排列顺序,将SSB依次映射到PRACH资源上,然后再按照PRACH资源的频域资源的排列顺序,将SSB依次映射到PRACH资源上,当SSB均与对应的PRACH资源映射时,完成一次映射。
例如,当第一配置信息中包括的msg1-FDM=4,ssb-perRACH-Occasion=1/4,SSB的数量为8时,则确定1个SSB与4个PRACH资源映射,且在PRACH资源在频域上的数量为4个,则先按照PRACH资源的时域资源的排列顺序,再按照PRACH资源的频域资源的排列顺序,对SSB与对应的PRACH资源进行映射,得到如图8所示的SSB与PRACH资源的映射关系图。
可选地,终端设备按照SSB的标签从小到大的顺序,且按照PRACH资源的时域资源从小到大的顺序,再按照PRACH资源的频域资源从小到大的顺序,可以依次确定SSB对应的PRACH资源。
例如,当SSB的标签为0-7时,则先对标签为0的SSB进行映射,再对标签为1的SSB进行映射,以此类推,直到对标签为7的SSB进行映射,即可确定标签为0-7的SSB对应的PRACH资源。
另外,终端设备根据第一配置信息中的配置参数,可以确定SSB与PRACH资源的映射方式,也就是确定了终端设备采用第一映射方式还是采用第二映射方式。
例如,当第一配置信息中包括的第一数量大于1时,且第二数量为8,第三数量为4,在此种情况下,按照PRACH资源的频域资源的排列顺序,再按照PRACH资源的时域资源的排列顺序,对SSB与对应的PRACH资源进行映射,确定的SSB对应的PRACH资源是彼此频分的,此时即可采用第一映射方式将SSB与对应的PRACH资源进行映射。
或者,当第一配置信息中包括的第一数量小于1时,且第二数量为8,第三数量为4,在此种情况下,按照PRACH资源的时域资源的排列顺序,再按照PRACH资源的频域资源的排列顺序,对SSB与对应的PRACH资源进行映射,确定的SSB对应的PRACH资源是彼此时分的,此时即可采用第二映射方式将SSB与对应的PRACH资源进行映射。
需要说明的是,本申请实施例中为了防止出现不同功能的终端设备所采用的不同映射方式下所采用的PRACH资源存在冲突的情况,在为终端设备配置PRACH资源时,配置不同的频域资源、不同的时域资源以及不同的前导码集合,以防止出现PRACH资源冲突的情况。
步骤504,终端设备根据SSB与PRACH资源的映射方式,确定SSB对应的多个PRACH资源。
终端设备可以检测网络设备发送的SSB,当终端设备检测到SSB后,可以确定该SSB的标签,再根据确定的SSB与PRACH资源的映射方式,确定该SSB对应的多个PRACH资源,确定的该多个PRACH资源为进行PRACH重复传输的可用资源,后续从该多个PRACH资源中,选择多个目标PRACH资源,通过多个目标PRACH资源进行PRACH重复传输。
例如,当终端设备确定的SSB对应的PRACH资源如图3所示时,当终端设备检测到的SBB的标签为SSB 1时,则可以确定SSB 1对应的4个PRACH资源。
或者,当终端设备确定的SSB对应的PRACH资源如图8所示时,当终端设备检测到的SBB的标签为SSB 0时,则可以确定SSB 0对应的4个PRACH资源。
需要说明的是,本申请实施例仅是以终端设备根据第一配置信息,确定第一SSB对应的多个PRACH资源为例进行说明。在另一实施例中,终端设备还可以采用其他方式直接确定第一SSB对应的多个PRACH资源,无需根据第一配置信息确定映射方式,再根据映射方式确定第一SSB对应的多个PRACH资源。
步骤505,终端设备从多个PRACH资源中,确定多个目标PRACH资源。
其中,该多个目标PRACH资源用于进行PRACH重复传输。
终端设备确定的多个PRACH资源中,由于存在频分的PRACH资源,当终端设备需要进行PRACH重复传输时,按照进行PRACH重复传输的机制,即可从多个PRACH资源中确定多个目标PRACH资源,采用确定的多个目标PRACH资源进行PRACH重复传输。
在一种可能实现方式中,终端设备确定的多个目标PRACH资源的时域资源不同。
终端设备根据第一SSB确定多个PRACH资源后,获取该多个PRACH资源中每个PRACH资源的时域资源和频域资源,终端设备从该多个PRACH资源中选择不同时域资源的多个目标PRACH资源,也表示获取的多个目标PRACH资源中,在不同的时域资源上,仅存在一个目标PRACH资源。
例如,在图3所示的SSB与PRACH资源的映射关系的基础上,SSB 1对应有4个PRACH资源,这4个PRACH资源位于同一时域资源,位于不同的频域资源,则从这4个PRACH资源中确定一个目标PRACH资源,选取的目标PRACH资源如图9所示。
或者,在图8所示的SSB与PRACH资源的映射关系的基础上,SSB 0对应有4个PRACH资源,且这4个PRACH资源位于不同的时域资源,这4个PRACH资源均为目标PRACH资源,选择的目标PRACH资源如图10所示。
在另一种可能实现方式中,终端设备确定的多个目标PRACH资源对应的时隙不同。
终端设备根据第一SSB确定多个PRACH资源后,获取该多个PRACH资源中每个PRACH资源的时域资源以及对应的时隙,终端设备从该多个PRACH资源中选择时域资源位于不同时隙的多个目标PRACH资源,也表示获取的多个目标PRACH资源中,在不同的时隙上,仅存在一个目标PRACH资源。
例如,在如图6所示的SSB与PRACH资源的映射关系的基础上,SSB 0对应有4个PRACH资源,但是第一个PRACH资源和第二个PRACH资源位于同一时隙中,则在确定目标PRACH资源时,将第一个PRACH资源和第三个PRACH资源确定为目标PRACH资源,选取的目标PRACH资源如图11所示。
本申请实施例提供的方法,通过确定第一SSB对应的多个PRACH资源,再从多个PRACH资源中确定多个目标PRACH资源,这多个PRACH资源用于进行PRACH重复传输,提供了一种确定PRACH资源的方法,能够实现PRACH的重复传输。
并且,本申请实施例通过从多个PRACH资源中确定位于不同时域资源的目标PRACH资源,或者确定位于不同时隙的目标PRACH资源,能够实现PRACH重复传输。
并且,按照PRACH资源的时域资源的排列顺序,再按照PRACH资源的频域资源的排列顺序,可以在时域资源上获取多个PRACH资源进行PRACH重复传输,能够减少PRACH重复传输的时延,保证PRACH重复传输的效率。
在基于图5的可选实施例中,图12示出了本申请一个示例性实施例提供的资源确定方法的流程图。在本实施例中,该方法还包括:
步骤1201,网络设备向终端设备发送第一指示信息。
步骤1202,终端设备接收第一指示信息。
其中,第一指示信息用于确定进行PRACH重复传输的起始PRACH资源。
步骤1203,终端设备根据第一指示信息,从多个目标PRACH资源中,确定进行PRACH重复传输的起始PRACH资源。
终端设备确定用于PRACH重复传输的多个目标PRACH资源后,还可以根据网络设备发送的第一指示信息,从该多个PRACH资源中确定起始PRACH资源,后续在该起始PRACH资源上进行初始传输,在位于该起始PRACH资源之后的PRACH资源上进行重复传输。
例如,当终端设备确定用于PRACH重复传输的10个目标PRACH资源后,接收到的第一指示信息用于确定第一个PRACH资源和第六个PRACH资源为起始PRACH资源,则终端 设备可以确定该第一个PRACH资源和第六个PRACH资源为起始PRACH资源。
在一种可能实现方式中,第一指示信息中包括重复传输次数,根据重复传输次数,从多个目标PRACH资源中,确定进行PRACH重复传输的起始PRACH资源。
当第一指示信息中包括重复传输次数时,则终端设备接收到该第一指示信息后,获取该第一指示信息包括的重复传输次数,以确定的多个目标PRACH资源中的第一个PRACH资源为起点,依次将间隔重复传输次数的PRACH资源确定为起始PRACH资源。
例如,当终端设备确定了20个目标PRACH资源后,第一指示信息中的重复传输次数为5时,则确定第1个PRACH资源、第6个PRACH资源、第11个PRACH资源、第16个PRACH资源为起始PRACH资源。
可选地,第一指示信息中还包括资源偏移值,根据资源偏移值和重复传输次数,从多个目标PRACH资源中确定起始PRACH资源。
当第一指示信息中还包括资源偏移值时,终端设备在从多个目标PRACH资源中确定起始PRACH资源时,在确定的多个目标PRACH资源中延后资源偏移值对应的数量的PRACH资源,再以延后的PRACH资源为起点,依次将间隔重复传输次数的PRACH资源确定为起始PRACH资源。
例如,当终端设备确定了20个目标PRACH资源后,第一指示信息中的资源偏移值为1,重复传输次数为5时,确定第二个PRACH资源、第7个PRACH资源、第12个PRACH资源、第17个PRACH资源为起始PRACH资源。
在另一种可能实现方式中,该第一指示信息中还包括跳频参数,终端设备获取第一指示信息中的跳频参数,确定在频域资源上的PRACH资源。
当在相同时域资源上包括多个PRACH资源时,通过该第一指示信息中的跳频参数,可以从多个PRACH资源中确定一个目标PRACH资源。
需要说明的是,本申请实施例仅是以终端设备根据第一指示信息确定起始PRACH资源为例进行说明。在另一实施例中,网络设备还可以向终端设备发送第二指示信息,终端设备接收该第二指示信息后,根据第二指示信息,从多个目标PRACH资源对应的时隙中,确定进行PRACH重复传输的起始时隙。
其中,在本申请实施例中,每个时隙中包括一个目标PRACH资源。
终端设备确定用于PRACH重复传输的多个目标PRACH资源后,每个目标PRACH资源均位于不同的时隙中,则还还可以根据网络设备发送的第二指示信息,从该多个PRACH资源对应的时隙中确定起始时隙,后续在该起始时隙中的PRACH资源上进行初始传输,在位于该起始时隙之后的时隙中的PRACH资源上进行重复传输。
在一种可能实现方式中,第二指示信息中包括重复传输次数,根据重复传输次数,从多个目标PRACH资源对应的时隙中,确定进行PRACH重复传输的起始时隙。
当第一指示信息中包括重复传输次数时,则终端设备接收到该第一指示信息后,获取该第一指示信息包括的重复传输次数,以确定的多个目标PRACH资源对应的时隙中的第一个时隙为起点,依次将间隔重复传输次数的时隙确定为起始时隙。
例如,当终端设备确定了20个目标PRACH资源后,这20个目标PRACH资源对应20个时隙,且第一指示信息中的重复传输次数为5时,则确定第1个时隙、第6个时隙、第11个时隙、第16个时隙为起始时隙。
可选地,第二指示信息中还包括时隙偏移值,根据时隙偏移值和重复传输次数,从多个目标PRACH资源对应的时隙中确定起始时隙。
当第一指示信息中还包括时隙偏移值时,终端设备在从多个目标PRACH资源对应的时隙中确定起始时隙时,在确定的多个时隙中延后资源偏移值对应的数量的时隙,再以延后得到的时隙为起点,依次将间隔重复传输次数的时隙确定为起始时隙。
例如,当终端设备确定了20个目标PRACH资源对应的时隙后,第一指示信息中的时隙偏移值为1,重复传输次数为5时,确定第二个时隙、第7个时隙、第12个时隙、第17个 时隙为起始时隙。
在另一种可能实现方式中,该第二指示信息中还包括跳频参数,且与第一指示信息中的跳频参数的作用相同,在此不再赘述。
本申请实施例提供的方法,可以根据第一指示信息,从多个目标PRACH资源中确定起始PRACH资源,再根据确定的起始PRACH资源进行PRACH重复传输,保证PRACH重复传输的成功。
