Abstract

Embodiments of the present invention disclose a method for controlling power of an uplink multiple-input multiple-output channel, and a user equipment that are used to support an uplink MIMO application scenario and implement control of transmit power of a UE. The method in the embodiments of the present invention includes: when total transmit power of a user equipment UE is greater than maximum allowed transmit power, performing, by the UE, power reduction for an uplink multiple-input multiple-output MIMO channel on which a main data transmission block and a secondary data transmission block are sent, so that the total transmit power of the UE after the reduction is less than or equal to the maximum allowed transmit 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 has the 99th Version (R99, Release99), Version 4 (R4, Release4), Version 5 (R5, Release5), Version 6 (R6, Release6), Version 7 (R7, Release7) and other versions.

[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 transmission speed of the uplink. The current H...
