1. A method for communicating in a wireless network including a base station (BS) and a set of mobile stations (MSs) located in a cell, comprising the base station performing steps of the method, comprising the steps of:
- transmitting a set of sounding requests using a set of beams, wherein there is one beam for each sounding request;
measuring qualities of sounding signals transmitted by the set of MSs in response to receiving the sounding request; and
grouping the set of MSs into subsets according to the qualities, wherein there is one subset associated with each beam.

Abstract
A base station transmits a set of sounding requests to a set of mobile station (MS) in a cell, using a set of beams, wherein there is one beam for each sounding request. Qualities of sounding signals transmitted by the set of MSs in response to receiving the sounding request are measured, and the set of MSs are grouping into subsets according to the qualities, wherein there is one subset of MSs associated with each beam.
