Abstract

The invention provides an uplink feedback method, user equipment and a NodeB. The method comprises the steps that the user equipment detects downlink data on at least two continuous downlink subframes; the user equipment carries out joint coding on feedback of the downlink data on the at least two continuous downlink subframes; and the user equipment sends joint uplink feedback information of theat least two continuous downlink sub-frames on an uplink subframe corresponding to the last subframe of the at least two continuous downlink sub-frames. The problem of how to carry out uplink feedbackwhen downlink bandwidths and uplink bandwidths are different is solved.

Description

[0001] This application is a divisional application with the application number 201380000109.9, the application date is January 21, 2013, and the invention name is the uplink feedback method, user equipment and base station. technical field [0002] The present invention relates to the technical field of communications, and in particular to an uplink feedback method, user equipment and a base station. Background technique [0003] In the prior art, the frequency bandwidth of the Universal Mobile Telecommunications System (UMTS for short) is 5 MHz, the network sends and receives data in the same uplink and downlink bandwidth, and the user equipment (User Equipment, UE for short) also uses the same bandwidth send and receive data. [0004] The narrow bandwidth UMTS system has higher spectral efficiency. For uplink, if the 5M bandwidth is divided into multiple subcarriers, the uplink interference between UEs on different subcarriers will be reduced. Therefore, UEs can obtain hi...
