摘要： Methods and apparatus supporting enhanced discovery operations in peer to peer networks are described. Peer discovery, based on direct peer to peer discovery between two mobile nodes can be somewhat limited, e.g., due to power limitations, processing power, and/or channel conditions. An access point, e.g., base station, monitors for and receives peer discovery signals conveying a set of identifiers from a wireless communications device. The access point retransmits at least one identifier in the set in a wireless peer to peer communications channel. Thus the access point effectively extends the peer discovery range for wireless communications devices utilizing the peer to peer network. Wireless communications devices can monitor for and recover the rebroadcast peer discovery signals from access points. Thus, via access point signaling a wireless communications device can be made situationally aware of other devices of interest which would be otherwise outside its discovery detection range.

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 for performing channel estimation and reporting back channel information or other information such as a suggested traffic transmission rate are described. A signal including a pilot signal of interest is received. Portions of the signal corresponding to the pilot signal are analyzed to determine if any of the portions, e.g., signal portions corresponding to individual tone symbols used to communicate the pilot signal, were subject to excessive interference, such as might be the result of collisions, rendering the signal portions unreliable. Signal sub-portions determined to be unreliable are excluded from a determination of the amount of pilot signal energy that was received. Signal interference is determined from a portion of the received signal on which the pilot signal was not transmitted. Channel information in the form of information and/or a suggested traffic rate may be reported back to the device which transmitted the pilot signal.

摘要： An uplink dedicated control channel reporting structure includes a plurality of different bit size reports, e.g. 1 bit, 3 bit and 4 bit reports, for reporting a wireless terminal's backlog information of uplink traffic request group queues. Smaller bit size reports are transmitted more frequently than larger reports. A 1 bit request report indicates whether or not there are any MAC frames of information to be communicated in a set of two request group queues. A 3 bit request report indicates an amount of backlog information corresponding to a first set of request group queues and a second set of request group queues. A 4 bit request report indicates an amount of backlog information corresponding to a set of request group queues. The 4 bit request report is capable of reporting information on any of a plurality of uplink traffic channel request group queues being maintained by the wireless terminal.

摘要： Methods and apparatus related to the sharing of wide area network (WAN) uplink bandwidth with peer to peer communication signaling usage are described. A base station transmits a signal to be used by a peer to peer wireless terminal in controlling its peer to peer transmit power level. The peer to peer wireless terminal receives and measures the strength of the base station signal. The measurement information is used in determining whether or not peer to peer signal transmission is permitted and/or in determining a peer to peer transmission power level. Current service level information and/or encoded information, e.g., an interference level indicator value, conveyed by the received base station signal are, in various embodiments, also utilized in determining a peer to peer transmission power level.

摘要： A terminal is assigned an active identifier for use while in an active state of a connection with a base station. The base station periodically broadcasts the status of the active identifiers for that base station, e.g., via status validation bits that indicate whether each active identifier is currently assigned to a terminal or not assigned to any terminal. The base station may also broadcast the identity (e.g., a scrambling mask) of the terminal assigned with each active identifier that is currently in use. If a terminal believes that it is assigned a particular active identifier, then the terminal checks the status validation bit for this active identifier. If this status validation bit indicates that the active identifier is currently in use, then the terminal may further check the scrambling mask sent for the active identifier in order to determine whether the terminal is actually assigned the active identifier.
摘要翻译：在处于与基站的连接的活动状态时，为终端分配有效标识符。基站周期性地广播该基站的活动标识符的状态，例如，经由状态验证比特，其指示每个活动标识符是否当前分配给终端或者未分配给任何终端。基站还可以广播分配有当前正在使用的每个活动标识符的终端的身份（例如，加扰掩码）。如果终端认为分配了特定的活动标识符，则终端检查该活动标识符的状态验证位。如果该状态验证位指示当前正在使用的活动标识符，则终端可进一步检查为活动标识符发送的加扰掩码，以确定终端是否实际分配了活动标识符。

摘要： Improved ways of communicating assignment signals using flash signaling are described, e.g., for wireless terminals with low SNR, that are more robust against large variation of channel gains due to e.g., frequency selective fading and fast fading in time. Coding and modulation methods and apparatus that have excellent properties against symbol erasures are described. The use of flash signaling provides an improved assignment channel having strong performance on the fading channel without compromising the performance on the AWGN channel. In one exemplary embodiment, the coding and modulation method can tolerate up to 5 erased symbols out of 8 transmitted symbols. One embodiment reduces or minimizes the sector interference on the flash assignment by improving or maximizing orthogonality between different sectors. In addition, one embodiment describes improved ways of swapping flash assignment tone-symbols in the presence other high priority signals, like sector pilots and sector null pilots.

摘要： Systems and methodologies are described that facilitate choosing parameters to utilize in a local area peer-to-peer network. The parameters may relate to tone spacing, cyclic prefix, symbol time, and the like. Further, the parameters may be a function of a state (e.g., peer discovery state, control related traffic state, data related traffic state, ) associated with the local area peer-to-peer network. Moreover, the local area peer-to-peer network may share spectrum with a wide area network; as such, parameters for the peer-to-peer network may be selected based on the type of wide area network (e.g., air interface technology) and/or wide area network related parameters.
