    • A method, a computer program product, and an apparatus are provided. In one configuration, the apparatus transmits a first broadcast signal including information indicating an intention to use a unicast resource for a broadcast. In addition, the apparatus transmits a second broadcast signal in the unicast resource. In another configuration, the apparatus, which is a first wireless device, receives a first broadcast signal from a second wireless device including information indicating an intention to use a unicast resource for a broadcast. In addition, the apparatus receives a first scheduling signal from the second wireless device in a scheduling resource. The first scheduling signal is for indicating a second intention to use the unicast resource for transmitting a second broadcast signal. Furthermore, the apparatus refrains from transmitting a second scheduling signal in the scheduling resource in response to the first scheduling signal.

    • Techniques for performing transmit power control based on receiver gain setting in a wireless communication network are described. In an aspect, a terminal A may estimate pathloss to another terminal B, e.g., based on a peer discovery signal received from terminal B. Terminal A may then determine a transmit power level for a peer-to-peer (PTP) signal (e.g., a paging signal) based on the estimated pathloss, a receiver gain setting at terminal B, and a target received power level for the PTP signal. Terminal A may send the PTP signal at the determined transmit power level to terminal B. In another aspect, terminal B may use different receiver gain settings in different time intervals to receive PTP signals from other terminals. Terminal A may then select a suitable time interval to send the PTP signal based on the pathloss and the different receiver gain settings used by terminal B.

    • Methods and apparatus for efficiently communicating small amounts of information relatively frequently in a wireless communications system are described. An access point's uplink timing frequency structure includes a set of dedicated uplink communications resources, e.g., expression advertisement interval air link resources, which may be in addition to regular traffic channel resources. The set of dedicated uplink communications resources comprises a small fraction of the total uplink communications resources. An individual one of the set of dedicated uplink communications resources can carry a small amount of information bits. An expression advertisement interval occurs relatively frequently. A wireless communications device, registered with the access point, is allocated one of the set of dedicated uplink resources. The wireless communications device can transmit information using its allocated resource in both a sleep state and an active state.
