Example Embodiment

[0043] Functional Overview

[0044] According to the embodiment of the present invention, in some cases, there may be no data that can be sent in the buffer of the UE, it may be necessary to stop the PERIODIC BSR TIMER, or not to start the PERIODIC BSR TIMER, otherwise it may cause meaningless empty BSR reporting or redundant For the problem of BSR triggering, an improved periodic buffer status report timer is proposed. In the embodiment of the present invention, after the terminal sends all the suspended data or BSR, it is checked whether there is still data to be sent in the buffer. If not, if the PERIODIC BSR TIMER is currently running, stop the PERIODIC BSRTIMER, if the PERIODIC BSR TIMER is not currently Run, do not start or restart the PERIODIC BSR TIMER.

[0045] In the case of no conflict, the embodiments in the application and the features in the embodiments can be combined with each other.

[0046] The preferred embodiments of the present invention will be described below...

Abstract

The invention discloses a processing method for a periodic buffer status report timer and a terminal. The processing method for the periodic buffer status report timer, which is disclosed by the invention, comprises that in the reporting flow of a buffer status report, after the terminal sends all suspension data of a buffer of the terminal, if data to be sent does not exist in the buffer and the periodic buffer status report timer is running, the periodic buffer status report timer is stopped. According to the technical disclosed by the invention, triggering of empty buffer status reports sent meaninglessly and redundant buffer status reports 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 for a periodic buffer state report timer in a buffer state report flow in a wireless communication system. Background technique [0002] In the Long Term Evolution (LTE for short) system of the third-generation mobile communication, the uplink Media Access Control (Media Access Control, MAC for short) scheduler is located in the base station (eNodeB, eNB for short), and allocates transfer resources. 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,...
