Embodiment Construction

[0071] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0072] In order to reduce the impact on the UE when CB resources are occupied and BSR fails to be sent, the present invention provides a BSR processing method, which aims to process BSR-related timers and cancel The operation of the BSR was improved.

[0073] Therefore, the processing of the BSR-related timer provided by the present invention includes at least one of the following methods:

[0074] A1. When receiving an uplink grant indicating a contention-based uplink resource, do not restart the retransmission BSR timer (retxBSR-Timer); the uplink grant is not limited to an uplink grant for sending a BSR;

[0075] A2. When the uplink resources are available, do not restart the retxBSR-Timer and / or the periodic BSR timer (periodicBSR-Timer); optionally, restart the retxBSR-Timer when receiving an indication that th...

Abstract

A method and apparatus for processing a Buffer Status Report (BSR) are disclosed in the disclosure. At least one of the following processing steps is performed when the BSR is transmitted using Contention Based (CB) uplink resources: A. restarting no retransmission BSR timer (retxBSR_Timer) when an uplink grant indicating CB uplink resources is received; B. restarting no retxBSR_Timer and/or no periodic BSR timer (PeriodicBSR_Timer) when the uplink resources are available; C. cancelling no triggered BSR when a BSR-related Media Access Control Protocol Data Unit (MAC PDU) is formed by occupying the uplink resources; and cancelling the triggered BSR when an indication for a successful transmission of the BSR-related MAC PDU is received; D. determining, according to a type of a triggered BSR, whether or not to cancel the triggered BSR, when a BSR-related MAC PDU is formed by occupying the uplink resources; and cancelling the triggered BSR when an indication for a successful transmission of the BSR-related MAC PDU is received. With the disclosure, the influence on User Equipment (UE) due to the failure of the BSR transmission when the BSR is transmitted by occupying the CB uplink transmission resources is decreased.

Description

technical field [0001] The invention relates to resource allocation technology in mobile communication, in particular to a buffer state report processing method and device. Background technique [0002] In the Evolved Universal Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network) of the third-generation mobile communication Long Term Evolution (LTE, Long Term Evolution) system, the uplink data shares the channel through the physical uplink (PUSCH, Physical Uplink Shared Channel) transmission; the evolved base station (eNB, evolved NodeB) allocates uplink radio resources to each user terminal (UE, User Equipment). The access technology adopted by E-UTRAN is Orthogonal Frequency Division Multiplexing (OFDM, Orthogonal Frequency Division Multiplexing) technology. Compared with the second-generation mobile communication system, the radio resource management of E-UTRAN system has large bandwidth and multiple time processes. Its wireless ...
