[0003] However, in the New Radio (NR) system, in addition to broadcast services, the secondary link can also support unicast services and multicast services, and can also support LTE Sidelink and NR Sidelink at the same time, which makes the uplink resources insufficient to report all The original SL BSR transmission method used when the data size of the secondary link logical channel buffer is no longer applicable

Abstract

The present invention provides a method and device for sending and receiving a secondary link buffer status report. The sending method includes: when the uplink resource is insufficient to report the total amount of buffered data of all secondary link logical channels, based on the buffered data Preset information, send a truncated secondary link buffer status report SL BSR, at least one field of the SL BSR is associated with the preset information; or report buffered data of all secondary link logical channels when uplink resources are insufficient When there is a total amount of data, at least one SL BSR format is sent based on a preset priority, and the SL BSR format is determined based on preset information of the cached data. The sending method can not only provide a buffer state reporting scheme with better applicability, but also enable the network device to obtain more comprehensive buffer state information of the terminal device, thereby better allocating resources to the terminal device and improving communication effectiveness.

Description

technical field [0001] The present invention relates to the technical field of communications, and more particularly to a method and device for sending and receiving secondary link buffer status reports. Background technique [0002] A secondary link (Sidelink, SL), also called a side link or a side link, is used for direct data transmission between terminal equipment (User Equipment, UE) without going through a network equipment. The sidelink buffer status report (Sidelink BufferStatus Report, SL BSR) is used for the sidelink terminal equipment (User Equipment, UE) to tell the network equipment a logical channel group (Logical channel group, LCG) based on the short-distance service destination address (Destination) The amount of data (in bytes) to be sent by all logical channels in ). In the Long Term Evolution (LTE) system, since the secondary link only supports broadcast services, when the uplink resources are insufficient to report the buffered data size of all secondar...
