Abstract: After determining that a P2P discovery process is to commence, one or both of (i) at least a portion of the P2P discovery process is delayed to permit communication via a non-P2P communication link, or (ii) at least a portion of the P2P discovery process is not performed to permit communication via the non-P2P communication link. Communications are performed via the non-P2P communication link during a time period that, prior to delaying or deciding not to perform the portion of the P2P discovery process, would have been allocated for the P2P discovery process.
Abstract translation: 在确定要发起P2P发现过程之后，（i）P2P发现处理的至少一部分被延迟以允许经由非P2P通信链路进行通信，或（ii）至少部分 不执行P2P发现处理，以允许通过非P2P通信链路进行通信。 在延迟或决定不执行P2P发现过程的一部分的时间段内，将通过非P2P通信链路进行通信，该时间段将被分配给P2P发现处理。

Abstract: A wireless medium often supports communications of multiple devices on different respective channels of the wireless medium. In some aspects described herein, a first frame is transmitted on a first channel of a wireless medium effective to prevent a member device of a peer-to-peer group from attempting to access the wireless medium, a second frame inviting a wireless device to join the peer-to-peer group is transmitted on a second channel of the wireless medium, and the first channel of the wireless medium is returned to thereby enabling a next attempt of the member device to access the wireless medium.

Abstract: A first device includes a physical-layer device, an adjusting module, and a power module. The physical-layer device transmits, during each of first windows, a request signal from the first device to discover one or more network devices. The first windows occur during a first period of time. The physical-layer device receives responses to the request signal from network devices. Each of the responses is received during a respective one of the first windows. The adjusting module, based on the responses to the request signal, determines whether to adjust lengths of second windows or a number of the second windows to occur during a second period of time. The second period of time occurs subsequent to and is a same length as the first period of time. The power module, during each of the second windows, transitions the first device between being powered ON and being at least partially powered OFF.

Abstract: A client network device includes a physical-layer device, a parameter module, an adjusting module, and a power management module. The physical-layer device, during each client traffic window that occur within a predetermined period, (i) transmits, over a network, a request signal from the client network device to discover other network devices in the network, and (ii) receives, from one or more of the other network devices, corresponding responses to the request signal. The parameter module monitors a first parameter of the client network device. The adjusting module adjusts a second parameter based on the first parameter. The second parameter indicates a number of the client traffic windows to occur within the predetermined period. The power management module transitions the client network device from an active mode to a sleep mode between consecutive ones of the number of the client traffic windows that occur within the predetermined period.

Abstract: Apparatus, methods, and other embodiments associated with obtaining schedule information to support snoop ranging are described. According to one embodiment, a method is performed by a station device on a computer network and includes establishing a network association with a network device of the computer network. The method also includes receiving schedule information from the network device without having to previously transmit to the network device to initiate acquisition of the schedule information. The schedule information is negotiated between other network devices communicating in the computer network, or between the network device and at least one of the other network devices. The schedule information is communicated to the network device and specifies timing associated with a ranging exchange between the other network devices, or between the network device and at least one of the other network devices, and may be used by the station device for snooping.

Abstract: The present disclosure describes methods and apparatus for beaconing within a wireless network based on an indication of distance. For certain example embodiments, in a wireless network in which a master device is a device configured to transmit a beacon within the wireless network, a first wireless communication device may determine, based on an indication of distance between two wireless communication devices, if the first wireless communication device is to act as a master device. For example, a wireless signal may be received. Based at least partially on the received wireless signal, an indication of distance between two wireless communication devices in a wireless network may be obtained. And based at least partially on the obtained indication of distance between the two wireless communication devices, it may be determined if a first wireless communication device is to act as a master device within the wireless network.

Abstract: A method for discovering devices in a peer to peer (P2P) wireless communication network is described. During a search state of a first communication device, a probe request is transmitted by the first communication device on a first channel included in a plurality of channels. During the search state, a probe response transmitted by a second communication device on the first channel is received by the first communication device. In response to the probe response, a ranging exchange with the second communication device is performed by the first communication device.
