摘要： Methods and apparatus for making communications decisions are described. In some embodiments, a method includes recovering a quality of service level from a transmission request response signal and making a decision whether or not to transmit traffic data based on the recovered quality of service level. In other embodiments a method includes recovering a first quality of service level from a first transmission request response signal which is in response to a first traffic transmission request signal, and making a decision, based on the recovered first quality of service level, whether or not to transmit a second transmission request response signal in response to a second traffic transmission request signal. In some embodiments, the phase of the transmission request response signal is used to communicate the quality of service level. The device transmitting the transmission request response may also transmit pilots which can be used as phase reference signals.

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.
摘要翻译：传输启动间隔定时结构与较低层定时结构结合使用，例如物理层定时结构。设备选择分组传输启动间隔的子集，然后限制分组传输的开始到那些间隔，从而减少冲突的可能性。分组传输可能发生在传输启动的启动间隔之外。在一些实施例中，分组传输长度被有意地限制为可以在物理层允许单个设备连续发送的时间量的一小部分中传输的大小，例如，等于或小于分组传输启动间隔的持续时间。这增加了即使在使用载波感测技术的情况下，多个设备将能够以短时间间隔成功地发送小分组的概率。

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.

摘要： An improved mechanism is provided that facilitates transmission of small packets within an ad hoc peer-to-peer network. A small packet is identified to a receiver within a control channel so that its lower power can be considered in an interference management protocol implemented among local peer devices. In a traffic slot, a transmitter voluntarily backs down on the transmitter power as a smaller packet will require much lower signal-to-noise ratio. This will improve the signal energy per bit per noise power density for the transmission as well as minimize the interference caused to other wireless communications happening in the same spectrum.

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.

摘要： Methods and apparatus relating to communicating in a system including relay stations are described. Various described methods and apparatus are directed to improved performance and/or mitigating interference in relay station boundary areas. Relay station transmission power is controlled based on at least one of time or frequency such that a transmission power level for a frequency is varied in a predetermined manner with time or such that different transmission power levels are used for different carrier frequencies. Different adjacent relay stations are intentionally configured to use different transmission power levels for the same carrier and/or have different time varying transmission power level profiles for the same carrier. A relay station performs access terminal scheduling based on access terminal location with respect to relay station boundary regions and transmission power level information.
