Embodiment Construction

[0042] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0043] figure 1 The wireless communication system in which the present invention can be implemented is shown.

[0044] Such as figure 1 As shown, the wireless communication system 100 includes a first base station 110 corresponding to a first cell, a second base station 120 corresponding to a second cell, a third base station 130 corresponding to a third cell, and a terminal 140.

[0045] The first base station 110 provides a first coverage area 110-a, the second base station 120 provides a second coverage area 120-a, and the third base station 130 provides a third coverage area 130-a.

[0046] The terminal 140 communicates with the first base station 110 through the wireless link 150. The terminal 140 communicates with the second base station 120 through the wireless link 160. The terminal 140 communicates with the third base station 130 through the wireless link 170. ...

Abstract

The invention discloses a method and device for transmitting uplink control information in a wireless communication system. The method includes the steps that the number of channel state information reports needing transmitting in the same subframe is determined; automatic retransmission requests are mixed to determine or deny the number of HARQ-ACKs or NACKs; whether dispatch requests need to be transmitted in the same subframe or not is determined; a corresponding physical uplink control channel format is selected to transmit the CSI reports and / or the HARQ-ACKs or NACKs and / or the dispatch requests in the same subframe according to the determined result so that reusing of multiple pieces of PUCCH format information on the same antenna port is avoided. According to the method and device for transmitting the uplink control information in the wireless communication system, good PAPE performance is achieved, the throughput is not reduced systematically, and limited resources are effectively utilized.

Description

Technical field [0001] The present invention relates to communication technology. More specifically, the present invention relates to a method and device for transmitting uplink control information. Background technique [0002] With the introduction of Coordinated Multiple Points (CoMP) in LTE-A Release 11, the UE needs to report corresponding uplink control information UCI at the same time in the same subframe to assist in resource coordination and coordination between different points. And perform channel-related scheduling. [0003] Among them, coordinated multi-point transmission refers to multiple transmission points that are separated geographically, cooperatively participating in data transmission for one terminal or jointly receiving data sent by one terminal. The multiple transmission points participating in cooperation usually refer to base stations in different cells. The data transmitted by each transmission point to the terminal is the same. [0004] The uplink contr...
