Embodiment 1

[0177] Such as figure 2 As shown, the transmission method of the embodiment of the present invention includes:

[0178] Step 21: The terminal performs a BSR trigger judgment.

[0179] Here, the determination of the BSR triggering conditions for the direct communication interface and the Uu interface complies with the existing protocol.

[0180] Step 22: The network device allocates the uplink scheduling permission.

[0181] The allocation of the uplink scheduling grant may be based on SR allocation, and may also be based on the BSR allocation previously reported by the terminal.

[0182] Step 23: When triggering the reporting of the direct communication interface BSR and the Uu interface BSR, determine the target BSR with higher priority among the direct communication interface BSR and the Uu interface BSR.

[0183] Specifically, the target BSR may be determined according to the foregoing first optional implementation manner or the foregoing second optional implementation ma...

Abstract

The invention provides a buffer status report transmission method and a terminal, and solves the problems that the priorities of a BSR of a direct communication interface and a BSR of a Uu interface are fixed. The terminal always preferentially sends the BSR of the Uu interface, and the transmission delay of a direct communication interface service is influenced. The method comprises the steps ofdetermining a target BSR with a higher priority in a first BSR and a second BSR according to a target logic channel under the condition of triggering reporting of the first BSR and the second BSR; sending the target BSR; wherein the target logical channel comprises a logical channel related to the first BSR and / or the second BSR. According to the method, the target BSR with the higher priority inthe first BSR and the second BSR is dynamically determined, and the target BSR with the higher priority is sent instead of always preferentially sending the BSR of the Uu interface according to a fixed priority sequence, so that the transmission delay of the direct communication interface service can be effectively ensured.

Description

technical field [0001] The invention relates to the technical field of communication applications, in particular to a buffer state report transmission method and a terminal. Background technique [0002] At present, for the buffer status report (Buffer Status Report, BSR) media access control element (MAC CE) of the direct communication interface and the Uu interface BSR MAC CE, the priority order is fixed, that is, the priority order of the BSR MAC CE of the Uu interface is always is higher than the BSR MAC CE of the direct communication interface. When the resources allocated by the base station are insufficient, the terminal will always send the BSR MAC CE of the Uu interface first, so the transmission delay of the direct communication interface service may be affected. Contents of the invention [0003] The purpose of the present invention is to provide a kind of transmission method and terminal of buffer state report, in order to solve the priority of the BSR of dire...
