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: 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.

Abstract: While a peer-to-peer (P2P) wireless network that includes both i) a first communication device and ii) a second communication device is not formed, and prior to the first communication device and the second communication device performing a group owner (GO) negotiation in connection with forming the P2P wireless network, the first communication device performs a ranging exchange with the second communication device. After performing the ranging exchange with the second communication device, the first communication device performs a GO negotiation with the second communication device.
