Non-uniform transmission of synchronization signals
First Claim
1. A method of wireless communication by a base station, comprising:
- dividing a region surrounding the base station into a plurality of sub-regions, wherein one sub-region of the plurality of sub-regions covers a greater area than at least one other sub-region of the plurality of sub-regions, and wherein the region is an angular region, and the plurality of sub-regions are a plurality of angular sub-regions;
assigning each beam of a plurality of beams of the base station to a respective sub-region of the plurality of sub-regions; and
transmitting at least one initial access signal in each direction of the plurality of beams using a respective beam of the plurality of beams, each direction of the plurality of beams corresponding to a respective sub-region of the plurality of sub-regions.

Abstract
The base station that is configured to transmit in a beamformed manner may set different transmission rates for different directions of the beams. During an initial access stage, the base station may determine how densely user equipments are located in various regions surrounding the base station, and may assign more beams for transmission of an initial access signal in an area with more UEs. The apparatus may be a base station. The base station divides a region surrounding the base station into a plurality of sub-regions, where one region of the plurality of sub-regions covers a greater area than at least one other region of the plurality of sub-regions. The base station assigns each beam of a plurality of beams of the base station to a respective sub-region of the plurality of sub-regions. The base station transmits at least one initial access signal in each direction of the plurality of beams using a respective beam of the plurality of beams, each direction of the plurality of beams corresponding to a respective sub-region of the plurality of sub-regions.
