METHOD AND APPARATUS FOR MAPPING/DEMAPPING RESOURCE IN WIRELESS COMMUNICATION SYSTEM

摘要

It is provided a method performed by a user equipment, UE, in a wireless communication system, the method comprising: receiving, from a base station, a signal comprising precoded data symbol pairs; identifying resource elements, REs, to be used for receiving the precoded data symbol pairs in available REs in an orthogonal frequency division multiplexing, OFDM, symbol of a resource block; demapping the precoded data symbol pairs from the identified REs; and decoding the precoded data symbol pairs, wherein at least one available RE in the OFDM symbol is not used for receiving the precoded data symbol pairs, in case that a difference between subcarrier indices of two available REs in the OFDM symbol is three or more, and wherein the demapping of the precoded data symbol pairs is skipped for the at least one available RE.
