Title: BEAM REFERENCE SIGNAL TRANSMISSION METHOD OF BASE STATION IN WIRELESS COMMUNICATION SYSTEM
Abstract:
A BRS transmission method and a base station are disclosed, the method comprising: generating BRSs for multiple antenna ports, corresponding to narrow-width beams generated by multiple antenna subarrays; mapping the BRSs for the multiple antenna ports to a resource region; and transmitting the BRSs mapped to the resource region to a terminal, wherein the BRSs are reference signals for the terminal to select a preferred beam among the narrow-width beams generated by the multiple antenna subarrays.
