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 supporting multiple modes of communication operation, e.g., with different parameters and/or frequency bands being used in the different modes of operation are described. One or more adjustments are made based on a signal or signals received in a first frequency band from a second communications device, e.g., an access router with reliable timing. The communications device selects between and operates in either the first frequency band, e.g., a WAN frequency band, or in a second frequency band, e.g., a LAN frequency band. The WAN and LAN frequency bands may be non-overlapping. One or more parameters used in the second frequency band have a predetermined relationship to one or more parameters used for communications in the first frequency band making the adjustment based on the signal received in the first frequency band relevant and useful to support communications in the second frequency band.

摘要： Methods and apparatus for supporting peer to peer communications are described. A peer to peer communications device uses both wide area network (WAN) uplink and downlink communications air link resources for peer to peer signaling. During an uplink share mode of operation a peer to peer wireless terminal uses a wide area network uplink communications band to communicate peer to peer signals, and the peer to peer wireless terminal implements a first transmission power control function. During a downlink share mode of operation, the peer to peer wireless terminal uses a wide area network downlink communications band to communicate peer to peer signals, and the peer to peer wireless terminal implements a second transmission power control function. The second power control function is different from the first power control function.

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.

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).
