摘要： Various schemes for reducing effects of interference within communication systems are disclosed. A transmitter transmits a signal in a first time interval and a scrambled version of the signal in a second time interval, which does not overlap with the first time interval. A receiver receives a composite signal including a signal transmitted from the desired transmitter as well as signals from interferers in the first or the second time interval. The receiver determines a dominant interferer and obtains knowledge of signal scrambling done by the interferer as well as the desired transmitter by sensing an identification associated with the interferer or the desired transmitter. This knowledge is employed to determine coefficients for combining the received composite signals received in the first and the second time interval in order to recover the desired signal in a manner that maximizes the SNR associated with the desired signal or completely cancels the dominant interference.

摘要： Methods and apparatus related to peer to peer communication networks are described. A peer to peer timing structure is implemented which includes recurring peer discovery intervals and traffic intervals. Some embodiments further include recurring paging intervals for peer to peer pages. A wireless communications device, supporting peer to peer communications and storing information defining the timing structure, determines a time reference point, facilitating a coarse level of synchronization with respect to the timing structure. The time reference point is determined based on a broadcast signal received from a communications device, e.g., a satellite, base station, or beacon signal transmitter. Multiple peer to peer wireless communications devices in a local vicinity thus obtain the same basic understanding as to the current relative point in time with respect to a common recurring peer to peer timing structure. Peer to peer timing synchronization is further refined based on received signals communicated between peers.

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： A peer to peer communications system implements scheduling of traffic intervals in a distributed manner utilizing connection priority and interference information. A peer to peer timing structure includes a user scheduling interval (2210), with ordered transmission request and response intervals, and an associated traffic interval. The priority associated with a request of an early interval is higher than the priority of a request of a later interval. A first device, connected to a second device, makes a decision as to whether or not to yield the traffic interval as a function of estimated interference that it will impose on higher priority connection receivers if it transmits during the traffic interval. The second device makes a decision as to whether or not to transmit a positive transmission request response signal as a function of a generated received signal quality value, based on received requests for its own and for higher priority connections

摘要： Methods and apparatus supporting peer to peer communications are discussed. A base station, serving as an access node for wireless terminals also communicates information supporting peer to peer communications. A base station transmits a beacon signal conveying information about a peer to peer frequency band and also receives user data from a plurality of wireless terminals, using the base station as a current point of network attachment. In some embodiments, the beacon signal is transmitted into the same frequency band being used for access node based communications and identifies a different frequency band which is to be used as a peer to peer frequency band. Alternatively, or in addition, in support of peer to peer communications, a beacon signal transmission apparatus, a free standing device which doesn't transmit user data, transmits a sequence of beacon signal bursts, each beacon signal burst including at least one high power beacon symbol.

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.
