Embodiment Construction

[0036] In order to make the technical solution of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] In the embodiment of the present invention, a BS (base station, base station) may be a station that communicates with a UE (user equipment, user equipment) or other communication stations, such as a relay station, and the base station may provide communication coverage of a specific physical area. The base station may provide communication coverage for macro cells, pico cells, femto cells, and / or other types of cells. A base station serving a macro cell may be called a macro base station, a base station serving a pico cell may be called a pico base station, and a base station serving a femto cell may be called a femto base station or a home base station. In different communication systems, the base station may be a different base station, for example, in an LTE s...

Abstract

The embodiment of the invention discloses a transmission mode switching method, device and system, relates to the technical field of wireless communication, and solves the problem of inaccurate switching during the mode switching process. The technical solution of the present invention is: the base station sends the CSI reporting mode corresponding to the target transmission mode to the UE; the base station sends DCI to the UE, and the DCI is used to instruct the UE to feed back the CSI measurement result according to the CSI reporting mode corresponding to the target transmission mode; the base station The CSI measurement result fed back by the UE according to the CSI reporting mode corresponding to the target transmission mode is received; the base station performs switching processing on the transmission mode of the UE according to the CSI measurement result. The embodiment of the present invention is suitable for performing mode switching on UE.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a transmission mode switching method, device and system. Background technique [0002] There are many kinds of TM (Transmission Mode, transmission mode) in the downlink of the LTE (Long Term Evolution, long-term evolution plan), such as R8 (release 8, version eight) of 3GPP (3rd Generation Partnership Project, third generation partnership project) , a total of 7 transmission modes, R9 (release 9, version 9) and R10 (release 10, version 10) respectively introduced a transmission mode, in the current LTE standard, as of R10, there are a total of 9 transmission modes. In the transmission mode switching in the existing LTE system, switching between TM3 and TM4 is more common. [0003] The judgment method of the existing transmission mode switching may include: in the TDD (Time Division Duplexing, time division duplex) mode, the measurement report to the uplink...
