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 apparatus and method are disclosed for generating a transmission connection identifier (CID) for a transmitter/receiver pair in a wireless network. The CID may be selected from or mapped to a hybrid CID space comprising a first set of orthogonal CIDs and a second set of non-orthogonal (random or pseudo-random) CIDs. When a transmitter device wants to initiate a peer-to-peer connection with a receiver device, the transmitter and receiver devices attempt to obtain a CID to identify their connection within a traffic channel in a shared frequency space. The first and/or second device attempt to select a CID from the first set of orthogonal CIDs. However, if a CID collision is detected, the first and second devices select their CID from the second set of non-orthogonal CIDs. The selected transmission CID may be used during a time slot or interval to facilitate communications between the first and second devices.

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 for communicating the location of a mobile wireless communications device are described. Codewords, e.g., values or sets of bits, are selected from a codebook mapping different codewords to corresponding pieces of location information. In a first approach location information is communicated by using codewords from different codebooks with the product, e.g., intersection of location information provided by the codewords, providing relatively detailed location information using relatively few bits. In a second approach user specific codebooks are defined for individual users. The codewords in the codebook corresponding to a particular user map to locations the individual specific user is likely to frequent. In another approach codewords are transmitted at different power levels and/or using different coding rates. Received codewords corresponding to a device may be used in combination to determine the location or refine the understanding of the device location.

摘要： Techniques for performing automatic gain control (AGC) at a terminal in a wireless communication network are described. In an aspect, the terminal may use different receiver gain settings to receive different types of signals in different time intervals. The terminal may determine a receiver gain setting for each signal type and may use the receiver gain setting to receive signals of that signal type. In another aspect, the terminal may determine a receiver gain setting for a future time interval based on received power levels for peer terminals expected to transmit in that time interval. The terminal may measure received power levels of signals received from a plurality of terminals. The terminal may determine a set of terminals expected to transmit in the future time interval and may determine the receiver gain setting for the future time interval based on the measured received power levels for the set of terminals.

摘要： Techniques for performing transmit power control based on receiver gain setting in a wireless communication network are described. In an aspect, a terminal A may estimate pathloss to another terminal B, e.g., based on a peer discovery signal received from terminal B. Terminal A may then determine a transmit power level for a peer-to-peer (PTP) signal (e.g., a paging signal) based on the estimated pathloss, a receiver gain setting at terminal B, and a target received power level for the PTP signal. Terminal A may send the PTP signal at the determined transmit power level to terminal B. In another aspect, terminal B may use different receiver gain settings in different time intervals to receive PTP signals from other terminals. Terminal A may then select a suitable time interval to send the PTP signal based on the pathloss and the different receiver gain settings used by terminal B.

摘要： Methods and apparatus related to peer to peer communication networks are described. A wireless communications device supports peer to peer communications with multiple peers. The wireless communications device determines its transmit timing synchronization based on a reference signal received from a node such as a base station, a satellite, or a beacon transmitter which does not transmit user data. The wireless communications device determines a plurality of different receive timing adjustments corresponding to different peer communications devices based on signals received from those peer communications devices. The wireless communications device stores the plurality of determined receive timing adjustment information corresponding to the different peer communications devices. The wireless communications device retrieves and applies stored receive timing adjustment information which matches the particular device which transmitted the signal attempting to be recovered.

摘要： Systems and methodologies are described that facilitate detecting and/or identifying peers in a local area peer-to-peer network. Times (e.g., peer discovery intervals) for performance of mutual detection and identification between peers may be synchronized (e.g., based upon a signal broadcast to the peers). Further, within each partitioned peer discovery interval, a wireless terminal may select a portion of time to transmit (e.g., broadcast) short messages that may be employed by peers to detect and/ identify the wireless terminal. Moreover, the remainder of the time within the partitioned peer discovery interval may be employed to listen to short messages received from peers.
