20130070636 | TRACKING MANAGEMENT SYSTEMS AND METHODS - A collaborative method for a node includes forming a local network with at least one other node using a lower power subsystem; selecting a master node from among the local network based on a first set of criteria; and communicating with a back end server over a wireless wide area network (WWAN) using a higher power subsystem. An apparatus may include a first subsystem for communicating with a local network; and a second subsystem having an active mode and an inactive mode, the second subsystem for communicating with a wireless wide area network (WWAN) when in the active mode, the apparatus selecting the active mode or inactive mode based on a set of criteria. | 03-21-2013 |
20140010107 | DETECTING SERVICES PROVIDED BY A WIRELESS NODE BEFORE DEVICE DISCOVERY AND CONNECTION ESTABLISHMENT - A wireless communication method embeds service related information, including a version of a service associated with the service related information, within an initial wireless access message. The method may also include broadcasting the initial wireless access message including the embedded service related information. Another aspect of the present disclosure includes a wireless communication method that indentifies service related information embedded within an initial wireless access message. The method may also establish a connection with an access node of the wireless communication network to receive a service when a version of a service associated with the service related information satisfies a predetermined condition. | 01-09-2014 |
20140020081 | Portable Token Device - Disclosed is a portable token device that may be used to assist a user in generating a PIN at one device and to then pass the PIN to another device such that the two devices can securely communicate with one another. The portable token device may include: an interface; and a processor. The processor may execute operations including: determining if a close proximity coupling through the interface to a first device has occurred; transmitting a PIN request to the first device; and obtaining a PIN. Further, the processor may determine if a close proximity coupling through the interface to a second device has occurred. If so, the processor may command transmitting the PIN to the second device. The second device may perform device registration with the first device based upon the received PIN. | 01-16-2014 |
20140241257 | SCALABLE DISCOVERY IN CONTENTION-BASED PEER-TO-PEER WIRELESS NETWORKS - Systems and methods for scalable discovery in contention-based peer-to-peer (P2P) networks are described herein. A method for managing access to a contention-based broadcast channel in a P2P wireless communication network as described herein includes obtaining one or more system timing parameters, the system timing parameters including at least a collision probability tolerance; and configuring a time structure for access to the contention-based broadcast channel using the system timing parameters, wherein the wakeup intervals are allocated between a contention period and a non-contention period and configuring the time structure comprises setting an upper-bound backoff counter value associated with the contention period as a function of at least the collision probability tolerance. | 08-28-2014 |
20150063318 | METHODS AND APPARATUS FOR MULTIPLE USER UPLINK - The disclosure provides methods and apparatuses for multiple user uplink. One aspect of the disclosure provides a method for wireless communication. The method comprises receiving a first wireless message from an access point indicating an uplink transmission opportunity and a target transmission duration for each of a plurality of user terminals including a first user terminal. The method also comprises changing a planned transmission duration of a second wireless message from the first user terminal to fit the target transmission duration. The method also comprises transmitting the second wireless message from the first user terminal over the target transmission duration. | 03-05-2015 |
20150078197 | APPARATUS AND METHOD FOR ASYNCHRONOUS PEER-TO-PEER DISCOVERY - Apparatus and method are provided for performing asynchronous discovery among multiple peers in a wireless peer-to-peer (P2P) network. In an aspect of the disclosure, a peer selects a duty cycle C corresponding to a probability that the peer is in either a scanning state or an advertising state, rather than a sleeping state, wherein the duty cycle C is selected in accordance with a power consumption of the peer. The peer also selects a first probability P | 03-19-2015 |
