Embodiment 1

[0166] Example 1: Differentiation by LCID

[0167] In this embodiment, the terminal judges whether the Sidelink BSR is triggered based on the Sidelink BSR MAC CE trigger condition. Once the Sidelink BSR is triggered, the terminal needs to organize the Sidelink BSR MAC CE.

[0168] When the terminal reports the buffer status, it is necessary to further distinguish between unicast and multicast / broadcast (or distinguish between unicast and multicast) for multiple logical channels belonging to the same logical channel group, and pass the corresponding Sidelink BSR respectively MAC CE reporting.

[0169] Based on the above approach, it is assumed that:

[0170] Destination index (or destination ID): used to indicate the communication target ID, assuming it occupies 3 bits;

[0171] LCG ID: logical channel group identifier, assumed to occupy 2 bits;

[0172] Buffer Size (Buffer Size): the size of the buffer state corresponding to the logical channel group, assuming that it occup...

Embodiment 2

[0175] Embodiment 2: Carrying indication information based on the destination index

[0176] The terminal judges whether the Sidelink BSR is triggered based on the sidelink BSR MAC CE trigger condition. Once the Sidelink BSR is triggered, the terminal needs to organize the Sidelink BSR MAC CE.

[0177] In this embodiment, the same BSR MAC CE is used for unicast and multicast / broadcast (or unicast and multicast) of the direct communication interface, and indication information is added in the BSR MAC CE to distinguish between unicast and multicast / broadcast (or to distinguish unicast or multicast). More specifically, the granularity of target identification is used to distinguish whether it is unicast or multicast / broadcast (or distinguish between unicast and multicast), that is, based on the destination address, indicate whether the logical channel corresponding to each logical channel group reported under the destination address is a unicast broadcast or multicast / broadcast ...

Embodiment 3

[0185] Embodiment 3: Carrying the indication information based on a logical channel group

[0186] The terminal judges whether the Sidelink BSR is triggered based on the sidelink BSR MAC CE trigger condition. Once the Sidelink BSR is triggered, the terminal needs to organize the Sidelink BSR MAC CE.

[0187] When the terminal reports the buffer status, it is necessary to further distinguish between unicast and multicast / broadcast (or unicast and multicast) for multiple logical channels belonging to the same logical channel group. When the Sidelink BSR MAC CE reports, the buffer status information corresponding to the unicast logical channel is placed in the BS domain corresponding to the unicast indication information, and the buffer status information corresponding to the multicast / broadcast logical channel is placed corresponding to the unicast indication information in the BS domain, but both LCG IDs are the same.

[0188] In this embodiment, the same BSR MAC CE is used fo...

Abstract

The embodiment of the invention provides a BSR reporting method, a terminal and network side equipment. The method comprises the steps that a terminal reports a BSR of a direct communication link, wherein the BSR is capable of at least distinguishing cache region states of unicast communication and multicast communication of a direct communication interface, or capable of at least distinguishing cache region states of unicast communication, multicast communication and broadcast communication of the direct communication interface. In this way, the network side equipment distinguishes the communication mode of the direct communication interface through the BSR, so that more accurate scheduling can be performed according to the communication mode, and the resource scheduling effect of the network side on direct communication is improved.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a buffer status report (Buffer Status Report, BSR) reporting method, a terminal and a network side device. Background technique [0002] The existing vehicle-to-everything (V2X) technology mainly supports the business of ensuring basic road safety, and the communication method adopted is broadcast communication. However, with the further development of the Internet of Vehicles technology, some new application scenarios will appear, such as: remote control, fleet communication, etc. Some or all of these application scenarios require unicast communication between terminals. In this way, since unicast or multicast (for example: broadcast or multicast) communication may occur in V2X communication, and V2X communication is direct communication, that is, direct communication between terminals, the communication between terminals is unicast Whether it is multicast co...
