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 base station or a second 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 base station, the plurality of groupings comprising a first grouping of resources having a first plurality of identical subsets of resources and a second grouping of 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; and transmitting a peer discovery signal on one subset of the identical subsets of said one grouping of peer discovery resources; wherein the determining to use said one grouping of peer discovery resources comprises: determining to use resources in the first plurality of identical subsets of resources when the wireless device has a path loss or a distance to the base station that is greater than a first threshold; and determining to use resources in the second plurality of identical subsets of resources when the wireless device has a path loss or a distance to the base station that is less than a second threshold. 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 base station or a second 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 base station, the plurality of groupings comprising a first grouping of resources having a first plurality of identical subsets of resources and a second grouping of 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; and transmitting a peer discovery signal on one subset of the identical subsets of said one grouping of peer discovery resources; wherein the determining to use said one grouping of peer discovery resources comprises: determining to use resources in the first plurality of identical subsets of resources when the wireless device has a path loss or a distance to the base station that is greater than a first threshold; and determining to use resources in the second plurality of identical subsets of resources when the wireless device has a path loss or a distance to the base station that is less than a second threshold. determining to use resources in the first plurality of identical subsets of resources when the wireless device has a path loss or a distance to the base station that is greater than a first threshold; and determining to use resources in the second plurality of identical subsets of resources when the wireless device has a path loss or a distance to the base station that is less than a second threshold.
