Embodiment Construction

[0036] Functional Overview

[0037] In the embodiment of the present invention, when the periodic buffer status report is triggered, if the uplink resource allocated by the base station is not received in the current transmission time interval, and the retransmission buffer status report timer is not running, start or restart (start Afterwards, restart the timing under certain circumstances) retransmission buffer status report timer. If the retransmission buffer status report timer is running, and the terminal receives uplink resources allocated by the base station for transmitting the buffer status report or new data, the terminal stops the retransmission buffer status report timer.

[0038] In the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0039] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be unde...

Abstract

The invention discloses a processing method for a retransmission buffer status report timer and a terminal. The processing method comprises that when a periodic buffer status report is triggered, if an uplink resource allocated by a base station is not received at the current transmission time interval and the retransmission buffer status report timer is not running, the retransmission buffer status report timer is started or restarted. According to the technical disclosed by the invention, triggering of the redundant retransmission buffer status report timers can be avoided and the performance of the system can be improved.

Description

technical field [0001] The invention relates to the technical field of digital mobile communication, in particular to a processing method and a terminal of a retransmission buffer status report timer (RETX_BSR_TIMER) in a wireless communication system. Background technique [0002] In the Long Term Evolution (LTE for short) system of the third-generation mobile communication, an uplink Media Access Control (Media Access Control, MAC for short) scheduler is located in a base station (eNodeB) and allocates transmission resources for terminals. Before allocating transmission resources for the terminal, the uplink MAC scheduler needs to know the state information of the current buffer zone of the terminal (User Equipment, referred to as UE for short). [0003] At present, the uplink MAC scheduler mainly obtains the state information of the UE's current buffer through the buffer state report (Buffer State Report, referred to as BSR) reported by the terminal, for example, whether ...
