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： A first device is configured to select and utilize a connection identifier (CID) for a peer-topeer communication connection between the first device and a second device in a wireless communications network. The CID is selected from a predetermined set of a plurality of CIDs. Prior to selecting the connection identifier, the first device monitors a CID broadcast channel to determine whether the CID is being utilized by other nearby connections. If it is determined that the CID is being utilized by another connection in the proximity, a different (unused) CID is selected. A transmission request is transmitted to the second device using a first transmission resource unit within a traffic control channel slot, the first transmission resource unit being determined as a function of the selected CID. The first device transmits traffic data to the second device in a traffic channel slot corresponding to the traffic control channel slot.

摘要： Systems and methodologies are described that facilitate identifying peers based upon encoded signals during peer discovery in a peer to peer network. For example, direct signaling that partitions a time-frequency resource into a number of segments can be utilized to communicate an identifier within a peer discovery interval; thus, a particular segment selected for transmission can signal a portion of the identifier, while a remainder can be signaled based upon tones communicated within the selected segment. Moreover, a subset of symbols within the resource can be reserved (e.g., unused) to enable identifying and/or correcting timing offset. Further, signaling can be effectuated over a plurality of peer discovery intervals such that partial identifiers communicated during each of the peer discovery intervals can be linked (e.g., based upon overlapping bits and/or bloom filter information).

摘要： Methods and apparatus well suited to decentralized traffic scheduling in wireless peer to peer network are described. An individual wireless terminal corresponding to a peer to peer connection makes a transmitter yielding or receiver yielding decision for a traffic slot. Quality of service information is disseminated as part of the scheduling control signaling. A scheduling control signal, e.g., a traffic transmission request signal or a traffic transmission request response signal, includes a pilot portion and a quality of service information portion. The pilot facilitates the recovery of the quality of service information by a plurality of different devices which may have different channel conditions with respect to the transmitter of the scheduling control signal. The different devices may benefit from utilizing the recovered quality of service information in making a yielding decision regarding traffic signaling in a traffic segment.

摘要： Methods and apparatus related to scheduling traffic slots in a wireless communications system, e.g., an ad hoc peer to peer communications network are described. An implemented timing structure includes multiple traffic transmission slots and multiple request blocks with different priorities corresponding to a traffic transmission slot. A wireless terminal determines its own block priority level. If a wireless terminal's determined block priority level is the highest block priority level the wireless terminal is allowed to transmit a traffic transmission request in the highest traffic transmission request block; otherwise, the wireless terminal is restricted from transmitting a traffic transmission request in the highest priority request block. A wireless terminal monitors for request and/or request response activity corresponding to other connections high priority block signaling, and uses the collected information to determine its own block priority.

摘要： Methods and apparatus related to a peer to peer wireless communications system supporting the association of multiple connection identifiers with a single connection between a pair of wireless terminals are described. A differentiated quality of service is supported by assigning different numbers of connection identifiers to different connections. The number of connection identifiers assigned to a wireless terminal pair for a connection is a function of one of: data rate, priority information, and quality of service information. Being allocated a higher number of connection identifiers results in being allocated a higher number of traffic transmission request resources, thus increasing the likelihood that the connection is permitted to use a traffic transmission segment. The allocation of connection identifiers is performed in a distributed manner in which handshake signaling occurs between a wireless terminal pair seeking to establish a connection, e.g., as part of a multi-step paging scheme.
