Abstract: A method computer program product and an apparatus for a transmit priority distributed backoff are provided. The apparatus forms a peer to peer communication link with a second apparatus. In addition the apparatus determines whether to transmit in an assigned resource for securing a transmit priority for transfer of data to the second apparatus based on a quality of service estimation. Furthermore the apparatus transmits to the second apparatus based on the determination. A method computer program product and an apparatus for a transmit priority token passing are provided. The apparatus forms a peer to peer communication link with a second apparatus. In addition the apparatus determines a transmit priority within the link based on a quality of service estimation. The transmit priority is a priority of transmission between the apparatus and the second apparatus in the link.

Abstract: Wireless communications devices with existing peer to peer links transmit e.g. in accordance with a recurring schedule quality of service related information corresponding to the existing links. The transmitted quality of service related information is e.g. information indicating an obtained quality of service for the existing link. In some embodiments quality of service related information is communicated in one of: a peer discovery signal a connection ID broadcast signal and a contention resolution signal. A wireless communications device seeking to establish a new peer to peer link receives quality of service related information corresponding to existing links and estimates a quality a service achievable on the new desired potential link based on the received quality of service related information. The wireless communications device decides whether or not to establish the new peer to peer link based on its quality of service estimate.
