Report method and device for buffer state report

Abstract

A report method and device for buffer state report is used for reducing transmission time delay of uplink data having high time delay requirements. The method includes that a terminal determines a first logic channel used for transmitting first-type service data, wherein the data processing time length required by the first type service data is smaller than a first set threshold value; the terminal is triggered based on the first logic channel and sends a first buffer state BSR to a base station and receives first uplink resource allocated for the first logic channel when the first logic channel has the first type service data that can be used for sending; the terminal occupies the first uplink resource and sends the first type service data.

Description

technical field

[0001] The present application relates to the technical field of communications, and in particular to a method and device for reporting a cache status report. Background technique

[0002] In a Long Term Evolution (Long Term Evolution, LTE) system, uplink conventional data transmission is based on dynamic scheduling. For a terminal in a connected state and uplink synchronization, if there is uplink data to be sent, the terminal needs to send an uplink scheduling request (Scheduling Request, SR) to the base station, and the base station sends an uplink scheduling grant (ie UL-Grant) to allocate uplink resources for the UE . However, the SR sent by the terminal to the base station does not carry information about the amount of data, so the terminal will send a buffer state report (Buffer State Report, BSR) on the corresponding uplink resource, and the base station will allocate the uplink resource occupied by the data to the terminal according to the BSR infor...
