Patent ID: 8812680

Claim:
A method of operating a wireless device, comprising: determining to use a first grouping of peer discovery resources of a plurality of groupings of peer discovery resources based on one of a path loss or a distance to a local base station if the path loss or the distance to the local base station is greater than a threshold and determining to use a second grouping of peer discovery resources of a plurality of groupings of peer discovery resources based on one of the path loss or the distance to the local base station if the path loss or the distance to the local base station is less than the threshold, the first grouping of peer discovery resources having a first plurality of identical subsets of resources and the second grouping of peer discovery resources having a second plurality of identical subsets of resources, each of the first plurality of identical subsets of resources extending over at least one of a different time period or a different number of subcarriers than each of the second plurality of identical subsets of resources; wherein the first grouping of peer discovery resources or the second grouping of peer discovery resources overlaps resources of an adjacent base station; and transmitting a peer discovery signal on one subset of the identical subsets of resources of the determined of said first grouping of peer discovery resources or said second grouping of peer discovery resources.
