Abstract

The embodiment of the invention discloses a power control method of an uplink MIMO (Multiple Input Multiple Output) channel, and user equipment (UE), and the method and the UE are used for supporting the application scenes of the uplink MIMO, and realizing control on the transmitted power of the UE. The method discloses by the embodiment of the invention comprises the following steps: the UE carries out power compression on the uplink MIMO channel sending a main data transmission block and an auxiliary data transmission block when the total transmitted power is larger than the maximum allowed transmitted power, so that the total compressed transmitted power of the UE is smaller than or equal to the maximum allowed transmitted power.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a power control method for an uplink multiple-input multiple-output channel and user equipment. Background technique [0002] With the rapid development of communication technology, Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access), as one of the mainstream technologies of the third generation mobile communication system, has been widely researched and applied worldwide. The current WCDMA Versions such as the 99th version (R99, Release99), the 4th version (R4, Release4), the 5th version (R5, Release5), the 6th version (R6, Release6), the 7th version (R7, Release7) have been arranged. [0003] In order to increase the data transmission rate and meet different needs, WCDMA introduced the High Speed ​​Uplink Packet Access (HSUPA, High Speed ​​Uplink Packet Access) technology in the R6 version, thereby improving the transmissi...
