detailed description

The technical solutions in the embodiments of the present disclosure will be described clearly and completely in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, but not all of the embodiments.

In the related technology, the long-term evolution (LTE, LongTerm Evolution) / enhanced long-term evolution (LTE-A, LongTerm Evolution) communication system supports a secondary link (SL, SideLink), which can be used by the user ( UE, User Equipment can directly transmit data without going through the network side equipment.

As shown in Figure 1, the network-side device is used as a base station for illustration. The base station may be an evolved base station (eNB or e-NodeB, evolutional Node B), which can communicate with UE1 through an uplink (UL, UpLink) and Downlink (DL, Down) realizes the transmission of uplink data and downlink data, and UE1 can directly communicate with other UEs, such as UE2, UE3, and UE4, as shown in Figure 1, through SL.

Among them, user equipment (UE, User Equipment), also known as terminal equipment (Mobile Terminal), mobile user equipment, etc., can communicate with one or more core networks via a radio access network (Radio Access Network, RAN) , The user equipment may be terminal equipment, such as mobile phones (or called "cellular" phones) and computers with terminal equipment, for example, may be portable, pocket-sized, handheld, built-in computer or vehicle-mounted mobile devices, they The wireless access network exchanges language and / or data.

In the related technology, the secondary link design in the LTE / LTE-A communication system is suitable for specific public safety services, such as emergency locations for fire or earthquake disasters; or for various services of IoV communications, such as : Basic security communications, advanced autonomous driving, formation, sensor expansion and other services. In addition, considering that the design of the secondary link in the LTE / LTE-A communication system only supports broadcast communication, it is mainly applied to basic security communication services. In this way, other advanced V2X services with strict quality of service (QoS) requirements in terms of delay and reliability can be supported by the design of SL in the 5G NR communication system. The 5G NR communication system can be used for LTE / The working frequency band above 6GHz which is not supported by the LTE-A communication system can support a larger working bandwidth, and the 5G NR communication system supports at least the interface between the network side device and the terminal device, where the network side device may be a 5G base station (gNB ).

In addition, the UE in the LTE / LTE-A communication system and the 5G NR communication system will report the BSR. Taking the basic line scheduling in the LTE / LTE-A communication system as an example, as shown in FIG. 2, when the UE needs the uplink data Data needs When sending, the UE sends the SR on the specified SR resource. The eNB receives the SR of the UE and knows that the UE has uplink data to send. The eNB schedules the UE to perform uplink transmission. That is, the UE can send on the resource corresponding to the UL grant of the eNB. BSR and part of the data, and then the eNB can know how much uplink data the UE has to transmit according to the BSR, and then the eNB can schedule the data according to the amount of uplink data and the priority of the data service, which shows that the role of BSR is for the UE It informs the eNB how much uplink data to transmit.

In the same way, regarding the allocation mode of the secondary link SL scheduling resource, after the UE reports the SR corresponding to the SL, it will report the BSR corresponding to the SL to the base station on the resource corresponding to the UL grant, and then the base station decides how much SL resource to allocate to the UE It is used for the transmission of secondary link data, that is, the role of the BSR corresponding to SL is that the UE informs the eNB of how much secondary link data to transmit through it.
