Problems solved by technology

[0006] Since in the prior art, one resource block (RB, Resource Block) can only support up to 18 pieces of ACK / NACK information, the number of different ACK / NACK information multiplexed by each RB is small; therefore, for a large number of data packets If the UE needs to feed back the corresponding ACK / NACK information in the uplink subframe, more RB resources are needed, which also affects the service transmission of PUSCH to a certain extent

Embodiment Construction

[0036] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0037] A method of information feedback provided by the present invention, such as figure 1 As shown, the method mainly includes the following steps:

[0038] In step 101, the UE generates corresponding ACK / NACK information according to the data packet sent by the BS through the working carrier.

[0039] In a broadband system, the BS sends a data packet to the UE through each working carrier or carrier component (Carrier Component), and each working carrier can send a data packet independently; of course, all working carriers can also jointly send a data packet. The UE generates corresponding ACK / NACK information according to the received data packet. When the data packet is received correctly, the UE generates the corresponding ACK information; when the data packet is received incorrectly, the UE generates the corr...

Abstract

The invention discloses an information feedback method, which comprises the following steps: generating corresponding acknowledgement character / non-acknowledgement character (ACK / NACK) information by user equipment (UE) according to a data pack sent by a base station (BS) through work carrier waves; binding a plurality of generated ACK / NACK information; and transmitting the bound feedback information to the BS through a physical uplink control channel (PUCCH). The invention also discloses an information feedback system and the user equipment. Through the binding operation executed on the ACK / NACK information, the invention improves the reuse efficiency of the ACK / NACK information, and saves resources.

Description

technical field [0001] The present invention relates to an acknowledgment / non-acknowledgement (ACK / NACK) information feedback technology in a long-term evolution (LTE) system, in particular to an information feedback method, system and user terminal. Background technique [0002] In a Long Term Evolution (LTE, Long Term Evolution) system, a base station (BS, Base Station) sends a data packet to a user terminal (UE, User Equipment) in a downlink (DL, Downlink) subframe, and the UE needs to transmit data packets in the uplink (UL, Uplink) ) feeds back acknowledgment / non-acknowledgement (ACK / NACK, Acknowledge / Not Acknowledge) information corresponding to the downlink subframe in the subframe. [0003] A physical uplink control channel (PUCCH, Physical UL Control Channel) of LTE is used to carry information such as ACK / NACK, channel quality indicator (CQI, Channel Quality Indicator) and scheduling request indicator (SRI, Scheduling Requirement Indicator). Wherein, the uplink PU...
