Embodiment Construction

[0042] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0043] For the uplink transmission in the LTE-A system in the prior art is no longer limited to single-carrier transmission, for UEs with unlimited power, when the amount of feedback information is large, simultaneous transmission of multiple PUCCHs may be considered.

[0044] In the embodiment of the present invention, an ACK / NACK group feedback method is provided by combining ACK / NACK multiplexing and multiple PUCCH transmission methods, which can effectively improve the transmissi...

Abstract

The present invention discloses a method for transmitting ACK / NACK (Acknowledgement Character / Negative Acknowledgement Character) information, the method comprises the steps of: obtaining the number of PUCCHs (Physical Uplink Control Channel) which can be transmitted by UE (User Equipment); grouping the ACK / NACK information according to the number of the PUCCHs; and merging the ACK / NACK information in each group, furthermore, performing multiplex transmission on the ACK / NACK information in each group. The method in the present invention combines the number of the PUCCHs which is supported bythe UE to feed back a plurality of ACK / NACK information in groups, so as to raise transmission efficiency of the system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and equipment for transmitting ACK / NACK information. Background technique [0002] LTE (Long Term Evolution, long-term evolution) is the evolution of 3G (3rd Generation, third-generation mobile communication system), LTE improves and enhances 3G air access technology, adopts OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) Use) and MIMO (Multiple Input Multiple Output, Multiple Input Multiple Output) as standards for wireless network evolution. LTE can provide a peak rate of downlink 100Mbit / s and uplink 50Mbit / s under 20MHz spectrum bandwidth, which improves the performance of cell edge users, increases cell capacity, and reduces system delay. Among them, the technical characteristics of LTE include high data rate, packet transmission, low delay, wide area coverage and backward compatibility. [0003] With th...
