1. A method for wireless communication, the method comprising:
receiving, by a base station, signals from a plurality of user equipment devices (UEs);
obtaining, by the base station, channel estimates associated with each of the plurality of UEs using the received signals;
calculating, by the base station, a first metric for each of the plurality of UEs according to the obtained channel estimates;
calculating, by the base station, a plurality of beams associated with the base station according to the obtained channel estimates;
determining, by the base station, one or more best beams from the plurality of beams associated with the base station;
determining, by the base station, a second metric for each of the plurality of UEs using the first metric;
segregating, by the base station, the plurality of UEs into a plurality of groups based on the determined one or more best beams and the second metric, each of the plurality of groups comprises one or more UEs;
performing beamforming, by the base station, on a control channel based on the one or more best beams; and
performing allocation, by the base station, of at least one of resources, modulation and coding scheme for the control channel based on the segregated plurality of groups.
