摘要： A wireless terminal receives peer to peer resource control information from a base station. The peer to peer resource control information is used by the wireless terminal in a peer to peer network to control transmission scheduling and/or resource utilization. The base station sends the control signals at a first rate which is slower than the rate at which wireless terminals make transmission decisions for traffic slots. During the intervals between receipt of the base station control signals, wireless terminals make transmission decisions with regard to multiple traffic segments. The decisions are also influenced based on peer to peer signaling occurring between the wireless terminals in the network for each traffic slot. Resource utilization feedback information is provided from the wireless terminal to the base station. Based on the feedback information the base station updates the resource utilization control information and sends updated resource utilization control signals to the wireless terminals.

Methods and apparatus are directed to implementations with closed groups, e.g., where the number of group members are fixed at a given time and known to one or more members of the group. Various embodiments are well suited to decentralized peer to peer wireless networks including a plurality of individual traffic resources, e.g., traffic slots and/or traffic segments, which may be independently scheduled. Approaches for implementing distributed scheduling for traffic air link resources which may carry group traffic signals and/or peer to peer traffic signals are described. Various aspects are directed to the transmitter side including: group traffic transmission request transmissions, reception of request response signaling, transmitter yielding decisions, group rate determination and/or group traffic data signaling. Other aspects are directed to the receiver side including: reception of group traffic transmission request signals, receiver yielding decisions, transmitting group request responses signals, and/or receiving group traffic signaling.

摘要： A transmission initiation interval timing structure is used in combination with a lower layer timing structure, e.g., physical layer timing structure. A device selects a subset of packet transmission initiation intervals and then limits initiation of packet transmission to those intervals thereby reducing the potential for collisions. Packet transmission may occur outside the initiation interval in which the transmission is initiated. In some embodiments, packet transmission length is intentionally limited to sizes which can be transmitted in a fraction of the amount of time the physical layer allows a single device to continuously transmit, e.g., in an amount of time which is equal to or less than the duration of a packet transmission initiation interval. This increases the probability that multiple devices will be able to successfully transmit small packets at short intervals on a regular basis even when carrier sensing techniques are used.

摘要： To mitigate interference between multiple peer-to-peer devices, transmitter yielding and/or receiver yielding may be performed among devices operating in a peer-to-peer network. Generally, a transmitter device will yield communications on a time slot to a higher priority transmitter device if it will cause unacceptable interference to a higher priority receiver device. Likewise, a receiver device may yield use of the time slot if interference is unacceptably high. Both transmitter and receiver yielding may be improved by use of beamforming at a receiver device. By utilizing beamforming information to make the transmitter and/or receiver yielding decisions, better interference mitigation may be achieved.
