Abstract

The disclosure provides a hybrid automatic repeat request HARQ feedback method and device. The method comprises determining a plurality of target HARQ results; the plurality of target HARQ results areHARQ results corresponding to the respective target physical downlink shared channel PDSCHs, where the multiple target PDSCHs are multiple PDSCHs scheduled by the current physical downlink control channel PDCCH; determining a group HARQ result according to the plurality of target HARQ results; the group HARQ result is used to characterize the plurality of target HARQ results; determining a targetnarrowband physical uplink shared channel NPUSCH; the target NPUSCH is an NPUSCH corresponding to the target resource for carrying the group HARQ result; transmitting, by the target resource, the group HARQ result, and sending the target NPUSCH to a base station. The present disclosure can characterize multiple target HARQ results by one group of HARQ results, improve the efficiency of performingHARQ feedback in the NB-IOT system, reduce the consumption of NPUSCH resources, and save the power of the NB-IOT device.

Description

technical field [0001] The present disclosure relates to the communication field, and in particular to a hybrid automatic repeat request (HARQ) feedback method and device. Background technique [0002] In recent years, the rapid development of the Internet of Things has brought many conveniences to human life and work. Among them, NB-IoT (Narrow Band Internet of Things, narrowband Internet of Things) technology is a typical representative of cellular Internet of Things technology. [0003] The basic framework of NB-IoT is formed in the release (version) 13 of LTE (Long Term Evolution, long-term evolution). Similar to traditional LTE scheduling, a PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) in NB-IoT schedules a PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) or PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) . NB-IoT devices need to receive and blindly detect PDCCH before receiving or sendi...
