METHOD AND DEVICE FOR SUPPORTING MULTIPLE ACCESS BY USING SWITCH NETWORK

The present disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting higher data rates after a 4th generation (4G) communication system such as long term evolution (LTE). An embodiment of the present disclosure provides a method by which a base station (BS) supports multiple accesses of a plurality of user equipments (UEs) by using a switch network (SN). The method may include obtaining channel state information (CSI) from the plurality of UEs, identifying a plurality of subarrays (SAs) formed from an antenna array having a plurality of antenna elements, identifying at least one SA to be allocated to the plurality of UEs from among the plurality of SAs, determining a structure of a SN corresponding to each of the plurality of UEs, and supporting the multiple accesses of the plurality of UEs, based on the determined structure of the SN.
