摘要： Methods and apparatus relating to scheduling of air link resources, e.g., traffic segments, in a wireless communications system are described. Various described methods and apparatus are well suited to wireless peer to peer networks in which traffic scheduling is decentralized, e.g. an ad hoc peer to peer network. An individual wireless terminal corresponding to a peer to peer connection which desires to transmit traffic signals make transmitter yielding decisions on a traffic slot by traffic slot basis. The transmitter yielding decision, in some embodiments, includes comparing a link quality estimate corresponding to a higher priority link intending to use the same traffic segment concurrently, to a dynamically generated transmitter yielding threshold. The dynamically generated transmitter yielding threshold is determined based on at least one of: quality of service information corresponding to its own link and historical link quality information corresponding to the higher priority link.

摘要： Methods and apparatus relating to scheduling of air link resources, e.g., traffic segments, in wireless communications are described. Various described methods and apparatus are well suited to wireless peer to peer networks in which traffic scheduling is decentralized, e.g. an ad hoc peer to peer network. A first wireless terminal receives a transmission request and quality of service information from a second wireless terminal corresponding to a connection. The first wireless terminal decides not to receiver yield, determines a request response transmission power level as a function of the received quality of service information, and transmits, at the determined power level, a generated request response signal. By controllably adjusting the transmission power level of a request response, transmitter yielding decisions of lower priority links are impacted, since lower priority links measure and use received power level information corresponding to request responses of higher priority links in their transmitter yielding decisions.

摘要： Techniques for transmitting signals on shared resources in a manner to detect and/or combat collision are described. In an aspect, a terminal may transmit a signal on a subset of resource elements in a resource block, and at least one null resource element with no signal may be used to detect for collision of the signal. In another aspect, different terminals may simultaneously transmit their signals on different subsets of resource elements in a resource block. These different subsets of resource elements may be pseudo-randomly selected to randomize interference. In one design, a terminal may determine a resource block to use for transmission of a signal, select a subset of the resource elements in the resource block, and transmit the signal on the selected resource elements, e.g., to at least one other terminal for peer-to-peer communication. The signal may be a peer discovery signal, a paging signal, etc.

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： Methods and apparatus for use in a wireless communications system in which traffic air link resources may be, and sometimes are, shared are described. Various described methods and apparatus are well suited for use in a peer to peer communications system in which transmission control decisions are made in a decentralized manner. An exemplary peer to peer communications system implements the scheduling of traffic intervals in a distributed manner utilizing connection priority information and interference information. An exemplary peer to peer timing structure includes a user scheduling interval and an associated traffic interval. The user scheduling interval includes a plurality transmission request/request response rounds. By utilizing multiple request/request response rounds, a transmission decision corresponding to a connection to yield in an earlier round can be overridden in a subsequent round, resulting in higher overall traffic throughput in the system.

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： Methods and apparatus supporting group communications in a peer to peer wireless network are described. 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.
