Title:
METHOD AND APPARATUS FOR DETERMINING BROADCAST BEAM WEIGHT IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/205252
Kind Code:
A1
Abstract:
Disclosed are a method and apparatus for determining a broadcast beam weight in a wireless communication system. The method in the embodiments of the present application comprises: acquiring an angular path loss spectrum of a target cell at the current moment, wherein the angular path loss spectrum comprises signal path loss values, for a plurality of directions, of a target base station in the target cell; determining a beam angle power spectrum according to the angular path loss spectrum, wherein the beam angle power spectrum comprises signal transmission powers, for the plurality of directions, of the target base station, and in the beam angle power spectrum, a signal transmission power for a direction, which has a relatively large signal path loss value in the angular path loss spectrum, is relatively large; determining a broadcast beam weight according to the beam angle power spectrum; and forming a target broadcast beam according to the broadcast beam weight.
