Embodiment Construction

[0043] The main realization principles, specific implementation modes and corresponding beneficial effects of the technical solutions of the embodiments of the present invention will be described in detail below in conjunction with each accompanying drawing.

[0044] Such as image 3 As shown, it is a flow chart of the BSR and SR processing method in Embodiment 1 of the present invention, and the processing process is as follows:

[0045] Step 31, the UE receives a contention-based transmission scheduling command sent by the base station;

[0046] Step 32, the UE sends a contention-based transmission to the base station according to the received transmission scheduling command, and the contention-based transmission includes the UE's BSR or all uplink data to be sent;

[0047] Step 33, the UE receives the competition success identification information sent by the base station;

[0048] Step 34, after receiving the contention success identification information, the UE cancels ...

Abstract

The invention discloses a method for processing a cache state report and a scheduling request and user equipment. The method comprises the steps of receiving a contention-based transmission scheduling command transmitted by a base station by UE (User Equipment); transmitting a contention-based transmission to the base station according to the received transmission scheduling command, wherein the contention-based transmission comprises BSR (Buffer State Report) of the UE or all uplink data to be transmitted; and after receiving contention success identifier information transmitted by the base station, cancelling the BSR and / or SR having been triggered while the contention-based transmission is transmitted. By using a technical scheme of the invention, the problem that the uplink data of the UE cannot possibly be scheduled in time because the triggered BSR and SR are cancelled after the UE finishes the transmission of the contention-based transmission in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for processing cache status reports and scheduling requests and user equipment. Background technique [0002] Both the Long Term Evolution (LTE, Long Term Evolution) system and the evolved LTE (LTE-A, LTE-Advanced) system are communication systems based on resource scheduling. ) to report to the base station the amount of uplink data waiting to be sent in the buffer of the UE, and the base station allocates uplink transmission resources for carrying uplink data to the UE according to the amount of uplink data that the UE needs to send, wherein, according to the UE triggering The triggering method of BSR reporting, BSR is divided into three types, specifically: [0003] The first type, regular BSR (Regular BSR): If the UE detects the arrival of data with a higher priority than the data currently stored in the cache, it will trigger the reporting of the Reg...
