Method and device for data decoding by terminal in wireless communication system
First Claim
1. A method of a terminal in a wireless communication system, the method comprising:
- receiving a configuration message including first information on available subframes for a downlink data transmission and second information on a number of subframes configured to carry a same downlink data repetitively;
identifying the available subframes configured to carry the same downlink data among a plurality of subframes based on the first information and the second information;
acquiring channel phase values for the available subframes;
compensating for, using one of the channel phase values as a reference value, a remaining channel phase value; and
decoding the same downlink data using the reference value and the compensated remaining channel phase value.

Abstract
The present disclosure relates to a communication technique for converging IoT technology with 5G communication systems for supporting higher data transmission rates than 4G systems and to a system therefor. The present disclosure can be applied to intelligent services (e.g. smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security- and safety-related services, etc.) on the basis of 5G communication technology and IoT-related technology. The method for data decoding by a terminal in a wireless communication system according to the present disclosure comprises the steps of: receiving subframes on the basis of a configuration; obtaining at least one channel phase value on the basis of available subframes, which are configured to transmit identical downlink data, among the received subframes; correcting the other channel phase value(s) with any one of said at least one obtained channel phase value as a reference value; and decoding the downlink data by means of the reference value and the corrected channel phase value(s).

8. A terminal comprising:
-
a transceiver configured to transmit and receive a signal; and a controller configured to; receive a configuration message including first information on available subframes for a downlink data transmission and second information on a number of subframes configured to carry a same downlink data repetitively, identify the available subframes configured to carry the same downlink data among a plurality of subframes based on the first information and the second information, acquire channel phase values for the available subframes, compensate for, using one of the channel phase values as a reference value, a remaining channel phase value, and decode the same downlink data using the reference value and the compensated remaining channel phase value. - View Dependent Claims (9, 10, 11, 12, 13, 14)
