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...
