Abstract

The invention provides a method and a device for sending control information in a multi-carrier mode. The method mainly comprises the following steps: constructing a message carrying the control information of associated data transmission of a main carrier and an auxiliary carrier according to the preset transmission format of the control information of the main carrier; and sending the message on the main carrier through an HS-SCCH (a high-speed shared control channel) channel. The method and the device can only use one main carrier to transmit the control information of the associated data transmission of the main carrier and the auxiliary carrier, enhance the sending power of the HS-SCCH channel of the main carrier and improve the total throughput of a cell, or can reduce redundant information in an encoding format of the HS-SCCH channel of the main carrier and the auxiliary carrier.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for sending control information in a multi-carrier mode. Background technique [0002] The data streams on different multi-carriers in the Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access) system can be regarded as data streams similar to multi-antennas. Considering the combination of multi-carrier and multi-antenna technologies in the future, the WCDMA system The high-speed shared control channel (HS-SCCH, High-Speed ​​Shared Control Channel) in the multi-carrier mode cannot fully adopt the multi-antenna HS-SCCH format. There must be room for independent control of multi-carriers, and how to Power is distributed among symmetrical carriers. [0003] At present, the coding format of the HS-SCCH channel combined with multi-carrier and multi-antenna technology has not been determined yet. [0004] In t...
