Cache status reporting method and device, terminal and base station

Abstract

The present invention provides a buffer status reporting method, device, terminal, and eNB; the buffer status reporting method being used for a wireless communications terminal capable of operating in a dual-connection wireless communications network comprising a master eNB and a secondary eNB, the processing method comprising: determining target upload data; determining, in the target upload data, first data transmitted by means of either a master eNB or a secondary eNB, and second data jointly transmitted by means of both a master eNB and a secondary eNB; sending to the target eNB the total value of the first data buffer size and the second data buffer size, the first data buffer size being the size of the first data, and the second data buffer size being smaller than or equal to the size of the second data. Using the technical solution provided by the present invention, an eNB can determine the data buffer size corresponding to data transmitted by means of said eNB, and allocate resources only for those data needing to be transmitted which are transmitted by said eNB, preventing the eNB from allocating resources to all data needing to be transmitted.

Description

technical field [0001] The present invention relates to the communication field, in particular to a buffer state reporting method, device, terminal and base station. Background technique [0002] In order to effectively improve the coverage and increase the communication capacity of the system, the 3GPP standard organization is currently studying the deployment of Small cells (small cells, or micro base stations) in the LTE-A system. The so-called Small cell is compared with the original Macro eNB (macro cell, or macro base station). Its main feature is that its radio frequency transmission power is low, so its coverage is usually smaller than that of the macro base station. In terms of deployment, small cells are usually within the existing coverage of macro base stations. According to different terrain conditions and customer needs, one or more micro base stations are deployed in specific areas to provide network coverage enhancement and wireless resources. Multiplexing, ...

Problems solved by technology

This means that the BSR report result of the UE received by the base station may be inaccurate

If the base station uses an inaccurate BSR report result, the base station may be misled, and thus allocate too many wireless resources to the UE to transmit data by mistake, which leads to waste of wireless resources and reduces system performance

[0014] For the above problems, there is currently no mechanism to deal with the problem
