Claim Text:
1. A method of determining antenna selection data, for use in a multi-antenna communications apparatus, comprising allocating a sensing period into a plurality of sequential sensing slots, the number of sensing slots being dependent on the number of antennas, for a first sensing slot, sensing in a communications channel of interest on a first antenna set, the first set comprising one or more of the plurality of antennas, to produce channel activity information for the first sensing slot, for a second sensing slot, sensing in the communications channel of interest on a second antenna set, the second antenna set comprising one or more of the plurality of antennas, the second set being non-identical to the first set, to produce channel activity information for the second sensing slot, and combining the resultant channel activity information for the plurality of sensing slots to form a channel activity report.
