Detailed Description

The technical solutions of the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which are derived by a person skilled in the art based on the embodiments of the application, fall within the scope of protection of the application.

The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or otherwise described herein, and that the "first" and "second" distinguishing between objects generally are not limited in number to the extent that the first object may, for example, be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/" generally means a relationship in which the associated object is an "or" before and after.

It should be noted that the techniques described in the embodiments of the present application are not limited to long term evolution (Long Term Evolution, LTE)/LTE evolution (LTE-Advanced, LTE-a) systems, but may also be used in other wireless communication systems, such as code division multiple access (Code Division Multiple Access, CDMA), time division multiple access (Time Division Multiple Access, TDMA), frequency division multiple access (Frequency Division Multiple Access, FDMA), orthogonal frequency division multiple access (Orthogonal Frequency Division Multiple Access, OFDMA), single carrier frequency division multiple access (Single-carrier Frequency Division Multiple Access, SC-FDMA), and other systems. The terms "system" and "network" in embodiments of the application are often used interchangeably, and the techniques described may be used for both the above-mentioned systems and radio technologies, as well as other systems and radio technologies. The following description describes a New air interface (NR) system for purposes of example and uses NR terminology in much of the description that follows, but these techniques are also applicable to applications other than NR system applications, such as generation 6 (6) ^th Generation, 6G) communication system.

In order to facilitate understanding of the embodiments of the present application, the following technical points are first described:

1. regarding the Sidelink Relay mechanism

The Relay technology in the wireless communication system is to add one or more Relay nodes between the base station and the terminal, and is responsible for forwarding the wireless signal once or more times, i.e. the wireless signal can reach the terminal only through multiple hops.

The wireless relay technology not only can be used for expanding cell coverage and compensating cell coverage blind points, but also can improve cell capacity through space resource multiplexing. For indoor coverage, the Relay technology can also play a role in overcoming the penetration loss and improving the indoor coverage quality.

Taking a simpler two-hop relay as an example, the wireless relay divides a base station-terminal link into two links of a base station-relay station and a relay station-terminal, so that a link with poor quality is replaced by two links with good quality, and higher link capacity and better coverage are obtained.

The Relay already supported in the long term evolution (Long Term Evolution, LTE) is a terminal-to-Network (U2N) Relay, i.e. one end of the Relay is connected to the UE, and the other end is connected to the Network side. The UE connected to the Relay is called Remote UE (Remote UE).

The New air interface (NR) will also study how to support the UE-to-Network Relay mechanism, and a typical scenario is shown in fig. 1. The Remote UE needs to transmit data with the network side, but finds the Relay UE as the Relay due to poor coverage, wherein a Uu interface is between the Relay UE and the base station, and a sidelink (PC 5) interface is between the Relay UE and the Remote UE. In general, a Relay UE is open and can serve any Remote UE.

NR will also study how to support the UE-to-UE (U2U) Relay mechanism, a typical scenario is shown in fig. 2: the middle is the Relay UE, and both ends are Remote UE, and both ends Remote UE is because signal quality is not good, and their data transmission is through the Relay UE in the middle. The Remote UE at the data transmitting end is also called Source UE (Source UE), and the Remote UE at the data receiving end is also called Destination or Target UE (Destination/Target UE).

2. Regarding NR sidlink BSR (buffer status report) format:

referring to fig. 3,NR Sidelink BSR, the design of LTE Sidelink BSR is followed, the only difference being that the length definitions of 3 fields (fields) are changed, i.e. LCG ID, destination Index and Buffer Size (BS):

LCG IDs occupy 3 bits and are divided into 8 groups at most.

Destination Index takes up 5There are a maximum of 32 groups of bits, corresponding to 32 Destination L2 IDs.

The Buffer Size is 8 bits long and there are 256 BS levels at most.

And the format is common for the case that the value N of Destination index is an even number and an odd number, respectively. As shown in fig. 3:

3. regarding the resource allocation pattern:

the resource allocation patterns of the Sidelink UE are classified into two types in total:

1) Base station scheduling Mode (Mode 1): BS schedules SL resource(s) to be used by UE for SL transmission(s), controlled by the network side equipment (base station) and allocates resources to each UE.

2) UE autonomous Mode (Mode 2): UE determinations, i.e. bs does not schedule, SL transmission resource(s) within SL resources configured by BS/network or pre-configured SL resources. Resources are autonomously selected by each UE.

According to the existing SL BSR mechanism, the upper limit of the number of LCG IDs is 8,Destination index and the upper limit of the number is 32. The upper limit of the current LCG ID number or Destination Index number may not be enough to meet the requirement of the Sidelink relay scene, so that the remote UE and/or the relay UE cannot well use the mode 1 resource allocation mode, and the base station cannot schedule the Sidelink resources for the terminal in the Sidelink relay scene, thereby influencing the communication efficiency.

The method, the device, the communication equipment and the readable storage medium for processing the SL BSR provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Referring to fig. 5, an embodiment of the present application provides a method for processing a SL BSR, where an execution body of the method may be a terminal, and specific steps include: step 501.

Step 501: the terminal executes a first operation according to at least one of information configured by a network side and preset conditions;

The first SL BSR format may be described as a new SL BSR format and the second SL BSR format may be described as an existing SL BSR format.

Optionally, the SL cache data related information at least includes information carried by a SL BSR.
