Title: METHOD AND APPARATUS FOR GRID MAPPING IN A WIRELESS COMMUNICATION SYSTEM
Abstract:
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Methods and apparatuses for grid mapping are described. A method for operating a base station comprises configuring grid mapping patterns for a plurality of terminals, transmitting, to the plurality of terminals, the grid mapping patterns, receiving, from the plurality of terminals, information on which a grid mapping is performed based on the grid mapping patterns, and identifying data of the information corresponding to each of the plurality of terminals based on the grid mapping patterns. Therefore, the terminal can hold a low peak-to-average power ratio, and the power consumption can be effectively saved. The base station can complete signal detection in a moderate detection complexity by multi-terminal joint detection. The detection complexity and the performance are balanced.
