Embodiment Construction

[0034] Embodiments of the present invention provide a method, device, and system for transmitting feedback information, which are used to solve the problem of UEs using CoMP for uplink transmission. How to feed back the second feedback information to the base station when the first feedback information is obtained and the second feedback information for indicating to the base station whether the same uplink data needs to be retransmitted is obtained based on the first feedback information. The embodiment of the present invention includes two cases, one is to transmit the second feedback information alone, and the other is to transmit the second feedback information and the ACK / NACK feedback information of the downlink data simultaneously.

[0035] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] see figure 1 As shown, a method for sending feedback information provided by an embodiment of...

Abstract

The invention discloses a transmission information feedback method, equipment and system with an aim to solve the problem that how UE (user equipment) adopting CoMP (coordinated multipoint transmission / reception) uplink feeds back second feedback information to a base station when receiving several first feedback information fed back by the base station involved in coordination for indicating whether the same uplink data are correctly received or not and receiving some second feedback information acquired and used for indicating whether the same uplink data need to be retransmitted or not to the base station on the basis of the first feedback information. The transmission information feedback method includes the UE determines the second feedback information to be fed back in the uplink subframes n according to the feedback sequence relation corresponding to the second feedback information; transmitting the second feedback information in the uplink subframes n through a PUCCH (physical uplink control channel) and / or PUSCH (physical uplink shared channel).

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, device and system for transmitting feedback information. Background technique [0002] Coordinated Multipoint Transmission / Reception (CoMP) technology refers to coordinated transmission between multiple geographically separated transmission points. Generally speaking, the multiple transmission points may be base stations of different cells, or may be multiple remote radio heads (Remote Radio Head, RRH) controlled by the base station of the same cell. Coordinated transmission between multiple transmission points can effectively reduce interference between different transmission points, and improve throughput of user equipment (User Equipment, UE), especially cell edge user equipment. According to the difference of uplink / downlink transmission, CoMP technology is divided into uplink CoMP transmission and downlink CoMP transmission, wherein, uplink CoMP transmissio...
