Abstract

Systems and methodologies are described that facilitate identifying devices in a wireless network and cognitively communicating with devices over utilized frequencies. Devices can be identified by receiving downlink resource assignments related to the devices, evaluating uplink transmissions thereover, and identifying the devices from one or more aspects of the uplink transmissions (e.g., an identifier in the transmission). Moreover, the uplink transmissions can be re-transmitted to a serving device to provide relay functionality for the transmissions. Additionally, peer-to-peer communication with the device and/or other devices can be facilitated by using a portion of available transmission power to re-transmit while using the other portion to transmit peer-to-peer communications. Thus, interference caused by the peer-to-peer communications is mitigated by additionally functioning as a relay using a portion of the transmit power.
