Apparatus and method for coordinated sensing of wireless devices in a communication system

摘要

A first base station is associated with a first quiet period, and a second base station is associated with a second quiet period. The quiet periods are coordinated so that an amount of overlap between the quiet periods is acceptable. For example, the quiet periods could be coordinated so that no overlap exists between the quiet periods. During the first quiet period, the first base station and/or an associated device (such as a CPE served by the first base station) performs in-band sensing to detect wireless devices that use a first frequency or channel also used by the first base station. During the second quiet period, the first base station and/or a coordinate device (such as a CPE served by the first base station and assisting the second base station) performs out-band sensing to detect wireless devices that use a second frequency or channel also used by the second base station.

主权项

1. A method comprising:
identifying one or more first quiet periods associated with a first base station; identifying one or more second quiet periods associated with a second base station; determining whether an amount of overlap between the first and second quiet periods exceeds a threshold; if the amount of overlap exceeds the threshold, selecting a different start time of the first or second quiet periods such that the overlap is reduced; and using the first and second quiet periods to initiate sensing of wireless devices when the amount of overlap between the first and second quiet periods does not exceed the threshold.
