摘要： A first eNB is adapted to determine a set of resources to allocate for D2D communications based on one or more network factors (e.g. number of D2D devices in a cell, etc,...) and transmit the set of resources allocated for D2D communications. A first UE may receive the set of resources allocated for D2D communications. A second UE may inform the first UE of a set of resources allocated for D2D communications by a second eNB. The first UE may determine a subset of resources to use for D2D communications with a second UE based on one or more D2D resource determination schemes, the resources determined being different to those allocated by the second eNB, and may signal the determined subset to the first eNB. The first eNB may receive the subset of resources and transmit a control signal indicating (i.e. comprising an identifier) that the subset of resources has been allocated for D2D communications (i.e. indicating the subset of resources for use during D2D communications).

摘要： Methods and apparatus are described for efficiently suppressing transmission of signals from devices which are using a first protocol, in order to allow the frequency spectrum being used by devices using the first protocol to be used briefly for communication between devices using an alternative communications protocol. In some embodiments, the first protocol is WiFi and the alternative signaling protocol is a non-WiFi peer to peer communications protocol. A wireless communications device, e.g., a peer to peer wireless communications device, generates a signal suppression utility metric (SSUM). The signal suppression utility metric provides an indication of how useful transmitting a transmission suppression signal, e.g., a S-CTS signal which may be a CTS to self signal, will be at a given point in time. The wireless communications device decides whether or not to transmit a transmission suppression signal as a function of the signal suppression utility metric.

摘要： Methods and apparatus are described which increase the probability and/or frequency that devices with comparatively faster clocks in a network than other devices in the network will transmit beacon signals are described. As a result, devices with faster clocks will tend to drive system synchronization to convergence faster than if all devices transmitted beacons at the same rate, thus facilitating more reliable maintenance of system synchronization since the devices with faster clocks will tend to transmit more frequently.

摘要： A decentralized approach to peer discovery channel selection is used in some embodiments. In some such embodiments, a mobile wireless terminal supporting a peer to peer signaling protocol, independently determines what channels to use for peer discovery without a central controller indicating the channel or channels to be used. Assuming channels are of a suitable quality, the channels having the best quality need not be identified, with channel selection being made on a predetermined channel ordering basis from those with suitable quality. Different wireless communications devices in the system use the same peer discovery channel selection process making it likely that the same channel or channels will tend to be picked to be used for peer discovery. Other embodiments are directed to implementing a centralized approach to peer discovery channel selection in which a central controller or base station selects channels to be used for peer discovery signaling.

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： 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).
