Abstract

The invention provides a method and a device for transmitting feedback information. The method comprises the following steps: the number of transmission blocks and feedback information corresponding to the number of the transmission blocks are confirmed; corresponding code words of the feedback information are confirmed according to pre-given feedback information and mapping relation of code words in a codebook, the codebook is corresponding to the number of the transmission blocks, code distance of any two code words is longer than or equal to half of length of a code word minus one; and the corresponding code words of the feedback information are sent. According to the method and the device for transmitting the feedback information, the codebook is corresponding to the number of the transmission blocks, and good code distances are provided, and therefore transmission quality of the feedback information can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and more specifically, to a method and device for transmitting feedback information. Background technique [0002] With the rapid development of communication technology, WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access), as one of the mainstream technologies of the third generation mobile communication system, has been widely researched and applied in the world. HSDPA (High Speed ​​Downlink Packet Access, High Speed ​​Downlink Packet Access) is introduced in the Rel-5 version formulated by 3GPP (3rd Generation Partnership Project, third generation partnership project) to increase the downlink data transmission rate. [0003] In HSDPA technology, NodeB (base station) sends data to UE (User Equipment, user equipment) through HS-DSCH (HighSpeedDownlinkSharedChannel, high-speed downlink shared channel) of the physical layer, and at the same tim...
