Abstract
Providing for cooperative sensing in wireless communications that improves user terminal throughput and minimizes interference is described herein. According to some aspects, a network entity, such as a base station, can assign a set of SUTs to measure a subset of wireless channels in a target frequency according to a cooperative sensing arrangement. In particular aspects, this assignment can be implemented so as to increase or maximize potential traffic throughput of those SUTs within the target frequency, in a given wireless time slot. In this manner, cooperative sensing can be structured so as to provide more efficient traffic communications within the target frequency.
