example 1

[0224] It is assumed that the first buffer status report of the remote terminal and the second buffer status report of the relay terminal are respectively triggered and reported at the relay terminal. like Figure 4 As shown, the interaction between the terminal and the network device includes the following steps:

[0225] Step 1, the remote terminal reports the first buffer status report of the remote terminal to the relay terminal. The first buffer status report is for the D2D link (also called Sidelink).

[0226] Preferably, the remote terminal reports the first buffer status report to the relay terminal through a buffer status report BSR MAC CE. Wherein, the BSR MAC CE of the remote terminal needs to include a destination ID (Destination ID), each logical channel group ID corresponding to each destination ID, and buffer state information corresponding to each logical channel group ID.

[0227] Assuming that a target ID has only one logical channel group ID, then the for...

example 2

[0245] It is assumed that the first buffer status report of the remote terminal and the second buffer status report of the relay terminal are both sent and reported at the relay terminal. like Figure 7 As shown, the interaction between the terminal and the network device includes the following steps:

[0246] Step 6: The remote terminal reports the first buffer status report of the remote terminal to the relay terminal. The first buffer status report is for the D2D link (also called Sidelink).

[0247] Preferably, the remote terminal reports the first buffer status report to the relay terminal through a buffer status report BSR MAC CE. Wherein, the BSR MAC CE of the remote terminal needs to include a destination ID (Destination ID), each logical channel group ID corresponding to each destination ID, and buffer state information corresponding to each logical channel group ID.

[0248]Assuming that a target ID has only one logical channel group ID, then the format of the BSR...

Abstract

The invention provides a buffer status report reporting and resource allocation method, a terminal and network equipment, and the method comprises the steps: sending a buffer status report to the network equipment, and indicating the type of the buffer status report, wherein the type of the buffer status report comprises a first buffer status report of the remote terminal and / or a second buffer status report of the relay terminal; according to the embodiment of the invention, when the relay terminal sends the buffer status report to the network equipment, the type of the buffer status report is indicated to the network equipment, so that the network equipment can identify whether the buffer status report is the first buffer status report of the remote terminal or the second buffer status report of the relay terminal, so that the network equipment can perform reasonable Sidelink resource allocation for the remote terminal and / or the relay terminal.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for reporting buffer state reports, resource allocation, terminals and network equipment. Background technique [0002] D2D (Device-to-Device, device-to-device) technology, that is, terminal direct technology, refers to the way that adjacent terminals can transmit data through direct links within a short distance without going through the central node (ie base station) For forwarding, there is no need for information transmission between terminals through traditional cellular links. [0003] In the future development of the mobile communication system, in order to better meet user needs, a D2D discovery (Device to Device Discovery) mechanism and a D2D communication (Device to Device Communication) mechanism are introduced. like figure 1 As shown, for an off-network terminal UE2 (also called a remote terminal), in order to allow it to communicate with the network,...
