Embodiment Construction

[0022] In the embodiment of the present invention, according to the number of RBs allocated to the user terminal and the scheduling priority weight corresponding to each RB, the first correspondence between RBs and LCGs is determined, and the first correspondence is sent to the user terminal for instructing the user terminal According to the data on each RB corresponding to the LCG, determine and report the BSR corresponding to each LCG. Since the base station determines the RB corresponding to each LCG according to the scheduling priority weight of the RB, so that the BSR corresponding to the LCG can be used as the specific situation of each RB corresponding to the LCG, the base station is notifying the user terminal of the RB corresponding to the LCG, and the user terminal reports After the BSR, the base station can know the specific status of each RB corresponding to the BSR, thereby improving the accuracy of the base station in adjusting the scheduling priority of the user ...

Abstract

The embodiment of the invention relates to radio communication technology, particularly a method and device for reporting BSR (Buffer Status Report). The method provided by the invention comprises the following steps: determining a scheduling priority weight allocated to a user terminal corresponding to each RB (Radio Bearer); determining a first relationship between the RBs and an LCG (Logical Channel Group) according to the quantity of the RBs allocated to the user terminal and the scheduling priority weight corresponding to each RB; and transmitting the first relationship to the user terminal to indicate the data of the user terminal on each RB corresponding to the LCG, and determining and reporting the BSR corresponding to each LCG. The method provided by the invention can help the base station to enhance the adjustment precision of scheduling priority of the user terminal, and improve the support system of QoS (Quality of Service).

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method and device for reporting a BSR (Buffer Status Report, buffer status report). Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, there are many different types of services, such as telephone calls, video calls, online games, ftp (File Transfer Protocol, file transfer protocol) downloads, streaming media, etc., which have different QoS (Quality Of Service, business quality), such as priority, delay, etc. The degree of QoS guarantee for different services of different user terminals (UEs) is directly related to user experience and is an important factor to measure the quality of a system. The guarantee of QoS is mainly given different scheduling priorities to different services by the base station (eNB) during scheduling. High-level implementation, that is, high priority is given to high-QoS services, and resource allocat...
