Example Embodiment

[0141] Example one

[0142] When the first type of UCI is ACK / NACK and the second type of UCI is CSI, the processing scheme on the terminal device side proposed in the embodiment of the present invention is as follows:

[0143] (1) First, for the generation of the first type of UCI, the specific processing procedure on the terminal device side is:

[0144] The terminal equipment is based on the number of configured carriers N, the transmission mode of each configured carrier, and the number of downlink subframes M that need to perform ACK / NACK feedback in the current subframe on each carrier i i , Generate ACK / NACK feedback information of the corresponding number of bits, where the number of bits of the generated ACK / NACK feedback information can be specifically obtained by the following formula:

[0145] B = X i = 0 N - 1 C i · M i ;

[0146] Wherein, B represents the number of ACK / NACK transmission bits determined by the terminal device to b...

[0199] Example two

[0200] When the first type of UCI is ACK / NACK and the second type of UCI is CSI, the base station side processing scheme proposed in the embodiment of the present invention is as follows:

[0201] (1) First, the base station needs to determine the number of transmission bits of the first type of UCI. The specific processing process is:

[0202] The base station according to the number of configured carriers N of the terminal equipment, the transmission mode of each configured carrier, and the number of downlink subframes M for which ACK / NACK feedback needs to be performed in the current subframe on each carrier i i To determine the number of bits of the ACK / NACK feedback information transmitted by the terminal, the specific determination method is consistent with the foregoing description, and the description is not repeated here.

[0203] (2) The base station determines the number of transmission bits of the second UCI, and the specific processing process is:

[0252] Example three

[0253] When the first type of UCI is CSI and the second type of UCI is ACK / NACK, the processing scheme on the terminal device side proposed in the embodiment of the present invention is as follows:

[0254] (1) First, for the generation of the first type of UCI, the specific processing procedure on the terminal device side is:

[0255] According to the CSI report type priority and / or carrier number, the terminal device selects a downlink carrier from the downlink carrier set with CSI feedback in the current subframe, and uses the number of transmission bits corresponding to the CSI report type of the downlink carrier as the current The number of CSI transmission bits transmitted in the subframe.

[0256] Alternatively, the terminal device selects one downlink carrier from the set of downlink carriers with CSI feedback in the current subframe according to the CSI report type priority and / or carrier number, and the maximum number of feedback bits C corresponding t...

Abstract

A first type of UCI that needs to be transmitted in a current subframe is generated by a terminal device; a second type of UCI that needs to be transmitted in the current subframe is generated on the basis of a threshold number of bits simultaneously transmitted with the UCI in the current subframe and of the number of bits transmitting the first type of UCI; the first type of UCI and the second type of UCI generated are transmitted on corresponding channel resources in the current subframe.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and equipment for transmitting uplink control information UCI. Background technique [0002] In the LTE-A (Long Term Evolution-Advanced, long-term evolution enhanced) system, the peak rate is required to reach 1Gbps downlink and 500Mbps uplink, which is a huge improvement over the LTE (Long Term Evolution, long-term evolution) system. [0003] Therefore, CA (Carrier Aggregation, Carrier Aggregation) technology is introduced to aggregate multiple continuous or discontinuous carriers under the same eNB (evolved Node B, evolved base station), and at the same time serve as UE (User Equipment, user equipment, i.e. terminal equipment) services such as figure 1 Shown is a schematic diagram of an application solution of the CA technology in the prior art. [0004] These aggregated carriers are also called CCs (Component Carriers, component carriers). Each cell ...
