摘要： Methods and apparatus related to peer to peer communication networks are described. A peer to peer traffic transmission request is linked to a subsequent traffic transmission interval having a fixed relationship to the transmitted transmission request. In various embodiments, when a first peer to peer device, which has requested a second device for authorization to use a linked subsequent traffic transmission interval, has been granted its request and has decided to transmit traffic during the subsequent traffic interval, the first device transmits a peer to peer pilot and receives a rate information signal, prior to transmitting the traffic signal. In some embodiments, the transmitted pilot signal and the received rate information signal are communicated using corresponding air link resources associated with the traffic interval.

摘要： Methods and apparatus are described for improved utilization of air link resources. A base station includes at least one of a plurality of receive antenna elements and a plurality of transmit antenna elements for communicating with a wireless terminal. The base station generates channel estimation vectors corresponding to wireless terminals using the base station, where a generated channel estimation vector includes different elements corresponding to different base station antenna elements. The base station determines a level of orthogonality between pairs of channel estimation vectors corresponding to different wireless terminals. At least some of the segments to be assigned by the base station are substantially overlapping, e.g., the segments overlap fully or to a high degree. Wireless terminal pairs which have substantially orthogonal channel estimation vectors are matched and assigned to substantially overlapping segments, and the power level associated with the segments is controlled to be substantially the same.

摘要： A protocol is provided that facilitates downlink concurrent peer-to-peer communications (within a time slot or traffic slot) between one device and many terminals as well as uplink concurrent peer-to-peer communications (within a time slot or traffic slot) between a plurality of terminals and one device. The concurrent peer-to-peer communications may take place within an ad hoc network of devices. To facilitate such operation, a time-frequency structure is provided within a control channel that allows the device and terminals to identify the peer-to-peer connections. This time-frequency structure also allows terminals to identify other sibling terminals that have a connection with the same device, thereby allowing to more efficiently performing interference mitigation. That is, sibling peer-to-peer connections with the same device may be treated different from other non-related peer-to-peer connects for purposes of interference mitigation in a wireless network.

摘要： To make efficient use of a frequency spectrum, a peer-to-peer network shares a wide area network (WAN) frequency spectrum as well as a time-frequency structure of the WAN, where the time-frequency structure includes a set of tones and symbols of an OFDM system. A first wireless terminal monitors the time-frequency structure of the WAN to determine which subsets of tone-symbols are unused for WAN and/or other peer-to-peer connections. Then, the first wireless terminal selects and uses an unused subset of tone-symbols within the time- frequency structure for its peer-to-peer connection with a second wireless terminal.

摘要： Methods and apparatus related to group communications in a wireless communications system, e.g., a peer to peer wireless communications system, are described. Methods and apparatus directed to 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, are described. 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 in a decentralized manner. Some features and/or aspects are directed to the use of individual group member acknowledgement signaling in response to a transmitted group traffic data signal. By monitoring for anticipated individual group member acknowledgment signals and identifying members which have not signaled a positive acknowledgment, re-transmission can be directed and/or tailored to a subset of the group.

摘要： In an ad hoc peer-to-peer communication network between wireless devices, a high priory first receiver device is configured to perform successive interference cancellation. A first pilot signal is received by the first receiver device from the first transmitter device. Similarly, a second pilot signal is received from a second transmitter device, the second pilot signal indicating that the second transmitter device intends to transmit a second traffic signal. The first receiver device determines a first and a second transmission rates for traffic transmissions from the first transmitter device. A control message is then transmitted by the first receiver device to the first transmitter device including the first and second transmission rates. Subsequently, the first receiver device wirelessly receives a traffic signal including a first traffic signal from the first transmitter device including a first and a second signal components generated from a first and a second codewords, respectively.

摘要： A first device is configured to select and utilize a connection identifier (CID) for a peerto- peer 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 management 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 management 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： Apparatus and method are provided for generating transmission connection identifiers (CIDs) in a non-orthogonal or pseudo-random manner identifying peer-to-peer connections in a wireless communication network. When a transmitter terminal intends to transmit to its peer receiver terminal, it just picks a transmission CID in a pseudo-random manner, without trying to avoid a similar transmission CID in a neighborhood. The method of generating this pseudo-random transmission CID may be agreed to between the transmitter and its intended receiver beforehand, for example, during the paging cycle. Also, the mapping between the transmission CID and a set of tone/symbols may not necessarily be orthogonal. In one embodiment, the transmission CID may also change over time in a pseudo-random fashion which is different between different transmitter/receiver pairs. With this property, two transmitter/receiver (Tx/Rx) pairs are not likely to use the same transmission CID for consecutive time intervals.

摘要： In an ad hoc peer-to-peer communications network, timing synchronization is facilitated between two or more nodes. A node can establish an original symbol timing and receive a first timing synchronization symbol from a peer node. A timing adjustment can be calculated based in part on the first timing synchronization symbol. An adjusted symbol timing can be established by adjusting the first symbol timing by the calculated timing adjustment amount. The adjusted symbol timing can be conveyed to one or more peer nodes, in order to facilitate timing synchronization among the nodes.
