Definitions
- the present application relates to the field of wireless communication technologies, and in particular, to a method, a device, and a storage medium for determining and configuring a scheduling request resource.
- LTE Long Term Evolution
- SR system scheduling request
- the LTE system is a scheduling-based system.
- a base station allocates time-frequency resources required for data transmission to a terminal device.
- the terminal performs downlink data reception or uplink data transmission according to a scheduling command of the base station.
- Uplink data transmission is scheduled by the base station.
- the base station scheduler determines the allocation of uplink resources, it will notify the terminal through an uplink grant.
- the base station scheduler performs uplink resource allocation based on the amount of uplink data to be sent by the terminal, that is, the buffer status of the terminal.
- the buffer is stored in the terminal. If the base station wants to know the information, the terminal needs to report the buffer status (Buffer Status Report (BSR)) to the base station.
- BSR Buffer Status Report
- Regular BSR (1) Triggered when data of higher priority than the data in the current buffer arrives or data in the originally empty buffer arrives; (2) retxBSR-Timer times out and is in the cache Triggered when data is available.
- Periodic (Periodic) BSR Periodic BSR-Timer triggers Periodic BSR when it times out.
- Padding BSR If the user equipment (UE) is in the organization of Medium Access Control Protocol (MAC) protocol data units (Protocol Data Units, PDUs), in addition to the data that needs to be transmitted There are also resources available to trigger Padding and BSR.
- MAC Medium Access Control Protocol
- PDUs Protocol Data Units
- the terminal When the terminal has a regular BSR trigger (the logical channel that triggers the regular BSR is not configured with SR masking), but the terminal does not have UL grant, the SR is triggered.
- SR After the SR is triggered, there are two ways to send the SR, namely: sending the SR (D-SR) through a dedicated scheduling request resource and performing SR (RA-SR) through a random access process.
- D-SR sending the SR
- RA-SR performing SR
- D-SR Dedicated SR
- RRC Radio Resource Control
- PUCCH Physical Uplink Control Channel
- Random access SR Use a random access procedure to send an SR.
- SR transmission The basic principle of SR transmission is: as long as D-SR resources are available, RA-SR is not used. RA-SR is used only when there is no D-SR resource configuration.
- the New Radio (NR) system SR is introduced as follows:
- the physical layer of the NR system supports multiple numerology / TTI.
- the concepts of baseband parameters (numerology) and transmission time interval (Transmission Time Interval, TTI) are as follows:
- the main difference between different numerology is that the sub-carrier spacing (SCS) supported by different numerology is different.
- the subcarrier interval supported by the 5G NR system includes at least 15KHz, 30kHZ, 60KHz, and 120kHz.
- the numerology corresponding to different subcarrier intervals is independent numerology.
- the numerology used by high-speed terminals is different from the numerology used by low-speed terminals; the numerology used by high-frequency and low-frequency terminals is also different.
- numerology that can be used by different services may be different, such as high reliability and ultra-low latency (Latency, Communication, URLLC) and enhanced The numerology used by Mobile Internet (Enhanced Mobile Broadband, eMBB) may be different.
- TTI is the transmission time interval.
- the TTI length is 1 ms.
- different TTI lengths are introduced, such as an Orthogonal Frequency Division Multiplex (OFDM) symbol length.
- OFDM Orthogonal Frequency Division Multiplex
- Different TTI lengths are used in 5G systems and can be applied to each numerology, that is, different numerology in 5G NR can use different TTI lengths, or use the same TTI length, and at any one time, a numerology is used for different terminals.
- the TTI length can be dynamically changed.
- the selection of the TTI length is mainly related to the service delay. For example, for the URLLC service, because it supports higher delay requirements, it may choose a shorter TTI length, such as the TTI length of 1 OFDM symbol.
- the numerology and / or TTI corresponding to a bearer / logical channel is configured through the network.
- the numerology and / or TTI corresponding to different logical channels may be the same or different.
- the SR information needs to reflect the numerology and / TTI corresponding to the logical channels that currently have data transmission requirements, so that the network-side equipment can make a reasonable uplink resource allocation for the terminal according to the SR.
- the design idea of NR is :
- the network side configured the correspondence between each logical channel of the terminal and the SR configuration, and the network side configured the correspondence between the logical channel and the numerology / TTI;
- the terminal has an SR trigger, then according to the corresponding relationship between the logical channel that triggered the SR, the logical channel configured on the network side, and the SR configuration, select the SR configuration used for SR transmission for SR transmission;
- the network side When the network side receives the SR, it determines the logical channel that needs data to be sent according to the correspondence between the logical channel configured on the network side and the SR configuration, and then determines the numerology and / or TTI corresponding to the UL grant and performs reasonable scheduling.
- These SR configurations are respectively mapped to different PUCCH resources (different PUCCH resources refer to different time / frequency domain resources occupied by the PUCCH).
- the NR system introduces multiple sets of SR configurations.
- the logical channels are configured by the network.
- the network will configure the mapping relationship between each logical channel and the SR configuration for the terminal.

- Step 303 The terminal performs SR resource selection.
- the terminal judges according to the trigger condition of the Regular BSR. Once the RegularSidelink BSR is triggered, but no Uu port uplink resource carries the Sidelink BSR resource, the SR is triggered. Once the SR is triggered, when SR resource selection is needed, it can be as follows:
- the Sidelink BSR For the Sidelink BSR, if the RegularBSR is triggered due to the retxBSR-Timer timeout, then select the SR resource corresponding to the QoS parameter corresponding to the Sidelink logical channel with the highest priority that currently has data to send.

- the network side configures a mapping relationship between a Sidelink interface (Sidelink interface) QoS parameter / QoS parameter combination and a Uu interface SR resource.
- Sidelink interface Sidelink interface
- the Uu interface SR resource may be embodied as a specific time / frequency resource, or may be a number of the time / frequency resource. There are two ways to divide its resources:
- the Uu interface uses SR resources for the Uu interface and SR resources for the Sidelink interface. No distinction is made in the time / frequency domain.
- the Uu interface uses the SR resources of the Uu interface and the SR resources of the Sidelink interface to distinguish in the time / frequency domain, so that the network can distinguish service priorities.
- the network side configures the mapping relationship between the current service QoS parameter / QoS parameter combination of the Sidelink interface and the SR resource of the Uu interface based on the auxiliary information reported by the terminal.
- the network-side behavior can be different:
- the auxiliary information reported by the terminal is: QoS parameters corresponding to the current service of the Sidelink interface of the terminal;
- the mapping relationship between the Sidelink interface QoS parameter / QoS parameter combination configured by the network based on the auxiliary information and the Uu interface SR resource cannot distinguish destinations with different configurations.

- PPPP, PPPR, PDB, and subsequent protocols introduce new QoS parameters for the Sidelink interface.
- the QoS parameter information of the Sidelink logical channel may specifically be PPPP and / or PPPR and / or PDB, and may also be other newly introduced Sidelink related QoS parameters.
- the network side can be configured as shown in Table 2.
- it can also be a combination between different values of the same parameter, which can be determined as required.
- Various combinations can be formed as long as they can form a mapping relationship with the SR resources, so that the terminal can determine the SR resources that send the SR.
- Step 403 The network side notifies the terminal of the mapping relationship between the QoS parameters of the Sidelink interface and the SR resources.
- the network side notifies the terminal of the configuration relationship between the QoS parameters of the Sidelink interface and the SR resources through dedicated signaling.
- the SR resource in the configuration signaling can be a time / frequency resource or the number of the SR resource.
- Step 404 The terminal performs SR resource selection.
- the terminal judges according to the trigger condition of the Regular BSR. Once the RegularSidelink BSR is triggered, but no Uu port uplink resource carries the Sidelink BSR resource, the SR is triggered. Once the SR is triggered, SR resource selection is required:
- the SR resource distinguishes the Destiantion ID
- the SR resources can be selected in one of the following ways:
- Multiple SR resources can be selected, that is, different SR resources corresponding to these Sidelink logical channels are used for SR requests.
- the Sidelink logical channel with the highest priority that currently triggers the SR is selected, and the SR resource is determined according to its QoS parameter and the mapping relationship.
- Step 405 The terminal reports the SR.
- Step 406 The network side allocates resources for the Sidelink BSR.
