Abstract: Methods and apparatus related to peer/network/service discovery in a mobile wireless system, e.g., an ad hoc peer-to-peer network are described. Transmission of discovery information, e.g., upper layer discovery information, is divided into a number of portions to be transmitted separately over time. Transmission of the individual portions is structured so as to enable flexibility in the frequency of the peer discovery transmissions as well as the monitoring of such transmissions. Various embodiments facilitate rapid discovery and/or secure discovery, e.g., selective discovery by trusted peers.

Abstract: An ad hoc peer-to-peer network is provided in which a transmitter wireless terminal is configured to establish a peer-to-peer communication link with a receiver wireless terminal over a shared communication channel. The transmitter wireless terminal may scale its transmit power as a function of a channel gain for the communication channel between the transmitter and receiver wireless terminals. The scaled transmit power may be utilized by the transmitter and receiver wireless terminals to perform link scheduling over the communication channel. For instance, the scaled transmit power may be used by the transmitter wireless terminal to perform a transmitter yielding with other neighboring transmitter wireless terminals utilizing the shared communication channel. Similarly, the scaled transmit power may be used by the receiver wireless terminal to perform receiver yielding with other neighboring receiver wireless terminal utilizing the shared communication channel.
