Problems solved by technology

In the scheme of repeated transmission of multiple information copies, the base station indicates the redundancy version of the data transmission when scheduling uplink / downlink data transmission using downlink physical layer control information (Downlink Control Information, DCI), but the terminal receives multiple redundant versions. However, it is not possible to clearly distinguish these redundant versions

Abstract

The present invention proposes a method and device for indicating a redundancy version, and a method and device for receiving a redundancy version, wherein the method for indicating a redundancy version for a base station includes: using one or more bits in the downlink physical layer control information The group indicates the number of multiple redundant versions; the number of multiple redundant versions is sent to the terminal. It is used for the terminal to send uplink data or demodulate downlink data according to the number of the redundant version, so as to ensure the reliability of data transmission.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular, to a method and device for indicating a redundant version, and a method and device for receiving a redundant version. Background technique [0002] The services in the current communication network are more and more diversified, not just simple voice calls, web page browsing, video and so on. Emerging services, such as Internet of Vehicles, telemedicine, industrial automation, etc., have a common feature of high real-time requirements and serious impact if errors occur. Therefore, such services need to ensure low latency and high reliability. [0003] In the current discussion of 5G standardization, URLLC (Ultra-Reliable and Low Latency Communication, high-reliability and low-latency communication) uses real-time scheduling on air interface scheduling. The following behavior is an example, once a base station has URLLC data to send to the terminal, the base station ...
