Embodiment Construction

[0128] In order to understand the characteristics and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the embodiments of the present invention.

[0129] In a Long Term Evolution (LTE, Long Term Evolution) system, the basic uplink scheduling process is as follows figure 1shown. When the UE has uplink data to send, the UE first sends SR on the specified scheduling request (SR, Scheduling Request) resource, and the base station learns that the UE has uplink data to send through the SR; the base station schedules the UE to send uplink, and configures a small part for the UE Resources, used to transmit BSR; UE sends BSR (may contain some data) to the base station on the uplink grant (UL grant) scheduled by the base stat...

Abstract

The invention discloses a method and device for reconfiguring a buffer status report (BSR) timer. The method comprises a step of sending a request message for reconfiguring the BSR timer to a base station, wherein the BSR timer is used for triggering BSR, a step of receiving a response message used for reconfiguring the BSR timer sent by the base station, wherein the response message carries reconfiguration parameters of the BSR timer. By using a technical scheme of the present invention, the BSR timer can be reconfigured through negotiation between UE and the base station, thus the BSR timeris flexibly changed, and the QoS of the service and the reasonable allocation of uplink resources are effectively ensured.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and device for reconfiguring a Buffer Status Report (BSR, Buffer Status Report) timer. Background technique [0002] In the communication system, the user equipment (UE, User Equipment) notifies the base station of how much data needs to be sent through the BSR, so that the base station allocates uplink resources to the UE accordingly. There are many ways to trigger the UE to report the BSR to the base station. One of the BSR reporting ways is: the UE periodically reports its own BSR to the base station. This way is triggered by the BSR timer set by the base station for the UE. [0003] However, since all logical channel groups use a fixed BSR timer, some services cannot guarantee the quality of service (QoS, Quality of Service) due to lack of uplink resources. Contents of the invention [0004] In order to solve existing technical problems, embodiments of the pr...
