Problems solved by technology

[0004] However, different types of data have different delay requirements. For example, URLLC (Ultra Reliable Low Latency Communication, Ultra Reliable Low Latency Communication) service is used in fields that require low delay such as the Internet of Vehicles, and has high requirements for timeliness; However, mMTC (massive Machine Type Communication) services are usually not sensitive to delay, and data can be delivered at long intervals. If the method of transmitting uplink HARQ feedback information provided by related technologies will affect low-time Delay requires the timeliness of sending HARQ feedback information in subframes, which in turn affects the delivery of low-latency service data, thereby affecting user experience

Abstract

The invention provides a method and a device for transmitting and acquiring uplink HARQ feedback information, wherein the method comprises the steps of acquiring a service priority sequence list of downlink subframes; according to the service priority sequence list, multiplexing the HARQ feedback information of the downlink subframes according to a sequence that the service priorities reduce from highest to lowest, and obtaining to-be-transmitted HARQ feedback information; successively assigning uplink subframes to the to-be-transmitted HARQ feedback information, and transmitting the to-be-transmitted HARQ feedback information to a base station. According to the method for transmitting the uplink HARQ feedback information, user equipment can preferably transmit the HARQ feedback information of the subframes with low time delay requirement. When the base station acquires a transmission error of time-delay-sensitive service data, the downlink subframes which carry the time-delay-sensitive service data can be preferably retransmitted, thereby shortening transmission time of the time-delay-sensitive service data.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a method and device for transmitting and acquiring uplink HARQ feedback information. Background technique [0002] With the development of wireless communication technology, mobile communication networks are gradually evolving to 5G networks. The 5G network can configure more downlink service types according to user needs. Therefore, in the LTE TDD (Long Term Evoluttion Time Division Duplexing) system of the 5G network, more downlink subframes are configured than uplink subframes. In the data transmission link, when the user equipment sends HARQ (Hybrid Automatic Repeat reQuest, Hybrid Automatic Repeat Request) feedback information to the base station, an uplink subframe for sending HARQ feedback information is required to simultaneously report multiple downlink subframes HARQ feedback information, wherein the HARQ feedback information includes: ACK signal ...
