Embodiment Construction

[0034] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0035] According to an embodiment of the present invention, a method for feeding back an uplink response message is provided.

[0036] In the present invention, according to the number of ACK / NACKs fed back by each uplink subframe specified by the uplink / downlink transmission timing relationship determined by the LTE TDD system, the downlink subframes for feedback in the same uplink subframe are defined as a feedback window, Wherein, in each feedback window, the ACK or NACK of N downlink subframes is fed back according to the sequence of the downlink subframes. In order to ensure the performance of transmitting multiple ACK / NACKs on the physical uplink control chann...

Abstract

The invention discloses a feedback method of an ascending response message, comprising the steps: receiving a descending scheduling signaling from a base station, wherein a bit counter for indicating a descending subframe number which is scheduled to a mobile table in a feedback window is arranged in the descending scheduling signaling; back feeding the ascending response message by operating theresponse message of N descending subframes of a feedback window or carrying out combined channel coding according to feedback content of PUCCH, wherein the N stands for the size of the feedback window. The feedback method of an ascending response message can increase the feedback efficiency of a TDD system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for feeding back an uplink response message. Background technique [0002] figure 1 Shows the frame structure of LTE (Long Term Evolution, long term evolution) system TDD (Time Division Duplex, time division duplex) mode, as figure 1 As shown, a 10ms radio frame is divided into two half frames, each half frame is divided into 10 time slots with a length of 0.5ms, and two time slots form a subframe with a length of 1ms. One field contains 5 subframes. In this frame structure, the subframe configuration has the following characteristics: [0003] (1) Subframe 0 is fixed for downlink; [0004] (2) Subframe 1 (hereinafter referred to as the special time slot subframe) contains 3 special time slots, which are DwPTS (Downlink Pilot Time Slot, downlink pilot time slot), GP (GuardPeriod, guard interval) and UpPTS (Uplink Pilot Time Slot, uplink pilot time slot), where: ...
