METHODS AND APPARATUS FOR PROVIDING FLEXIBILITY IN PEER DISCOVERY RANGE AND FREQUENCY OF UPDATES
First Claim
1. A method of wireless communication, comprising:
- transmitting a first peer discovery signal with a first periodicity in a first set of peer discovery resources;
determining an energy on an allocated peer discovery resource of a second set of peer discovery resources;
refraining from transmitting a second peer discovery signal in the second set of peer discovery resources when the energy is greater than a threshold; and
transmitting the second peer discovery signal in the second set of peer discovery resources with a second periodicity less than the first periodicity when the energy is less than the threshold.

Abstract
A method, a computer program product, and an apparatus for wireless communication are provided. The apparatus transmits a first peer discovery signal with a first periodicity/temporal frequency in a first set of peer discovery resources. The apparatus determines an energy on an allocated peer discovery resource of a second set of peer discovery resources. The apparatus refrains from transmitting a second peer discovery signal in the second set of peer discovery resources when the energy is greater than a threshold. The apparatus transmits the second peer discovery signal in the second set of peer discovery resources with a second periodicity/temporal frequency less than the first periodicity/temporal frequency when the energy is less than the threshold. The apparatus may utilize the first set of peer discovery resources every period and the second set of peer discovery resources once every N periods in which once every N periods is the second periodicity.
