US 2020/0028650 A1 · ADAPTIVE RETRANSMISSION METHOD AND DEVICE FOR DELAY REDUCTION IN WIRELESS CELLULAR COMMUNICATION SYSTEM

Abstract

Disclosed are a communication method for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and a system therefor. The disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security and safety-related services, and the like) on the basis of a 5G communication technology and IoT-related technology. In addition, disclosed in the specification are: an adaptive retransmission method and device for delay reduction; a method and a device for selecting radio resource allocation and data size; and a method and a device for performing setting so as to enable different channels to share DMRS with each other.

Claims15

Dependent claims

A method by a terminal for receiving a reference signal (RS) in a wireless communication system, comprising:

receiving, from a base station, information indicating that a plurality of channels share a reference signal;
receiving the reference signal on a first channel;
and
performing channel measurement of a second channel different from the first channel using the reference signal received on the first channel.
