Cache status report reporting method and device

Abstract

Embodiments of the present invention provide a buffer status report reporting method and device. A user equipment includes: a receiving module, configured to receive first uplink resource scheduling information sent by a base station, and the first uplink resource scheduling information is used to indicate the UE allocated The first uplink resource; a processing module, configured to determine whether the first uplink resource can carry all the BSRs of the UE; a sending module, configured to transmit the UE on the first uplink resource if the processing module determines that the first uplink resource cannot carry all the BSRs of the UE Sending the first part of all the BSRs of the UE to the base station, the first part does not include all the BSRs of the UE; the receiving module is also used to receive second uplink resource scheduling information sent by the base station, and the second uplink resource scheduling information is used to indicate The second uplink resource allocated by the UE; a sending module, further configured to send the second part of all BSRs of the UE to the base station on the second uplink resource.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wireless communication, and in particular, to a method and device for reporting a cache status report. Background technique [0002] A device-to-device (Device to Device, D2D) communication technology is a technology for direct communication between terminals. The difference between D2D communication and cellular communication technology is that in D2D communication, the data sent by the terminal does not need to be transmitted by the base station, but is directly transmitted through the air interface between the terminal and the terminal, thereby reducing the time delay for data forwarding through the base station. [0003] A terminal performing D2D communication may be called a D2D device, and multiple D2D devices form a D2D communication group, and D2D communication is performed between D2D devices in the same D2D communication group. D2D devices have two resource scheduling ...

AI Technical Summary

Problems solved by technology

[0004] The characteristic of D2D communication is that a D2D device may communicate with multiple other D2D devices (or multiple D2D communication groups) at the same time, so the BSR reported by the D2D device may include the D2D device communicating with multiple other D2D devices (or multiple D2D communication groups). group) communication data volume, resulting in relatively large uplink resources required to send the D2D BSR

In the base station scheduling resource mode, the uplink resources allocated by the base station for D2D devices to send BSR are limited, which may cause the D2D device to be unable to send all BSR information to the base station
