Abstract

The invention relates to the technical field of mobile communication, in particular to an information transmitting method, an information receiving method and equipment, which are used for solving thetechnical problem of high system overhead when UE feeds back ACK / NACK corresponding to a downlink subframe to a base station. In embodiments of the invention, a terminal can send feedback informationfor a downlink sub-frame to network equipment in a first feedback mode, i.e., a first codebook of the feedback information is determined by using an instantly scheduled downlink sub-frame set, whichis equivalent to the feedback for the downlink sub-frame actually scheduled by the network equipment; and the feedback of the information of the downlink sub-frame which is actually not scheduled by the network equipment can be avoided as much as possible, the number of bits comprised in the first codebook is smaller than the number of bits required to be fed back by the terminal in the prior art,and the system overhead is saved to a greater extent compared with that in the prior art.

Description

[0001] This application is aimed at the Chinese Patent Application No. "201580080432.0" and the priority date is August 14, 2015. A divisional application filed with the benefit application. technical field [0002] The present invention relates to the technical field of mobile communication, in particular to an information sending and receiving method and device. Background technique [0003] LTE (Long Term Evolution, long-term evolution) adopts the HARQ (Hybrid Automatic Repeat Request, hybrid automatic repeat request) mechanism, the following behavior example, UE (User Equipment, user equipment) receives the PDSCH (Physical Downlink Shared Channel, After the information carried by the physical downlink shared channel), if the reception is correct, the UE feeds back ACK (Acknowledgment, confirmation response) through the PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) of the corresponding uplink subframe. The PUCCH of the uplink subframe feeds b...
