20140328168 | APPARATUS, SYSTEM AND METHOD OF ADJUSTING TRANSMISSION INTERVALS FOR DISCOVERY FRAMES - Some demonstrative embodiments include apparatuses, systems and/or methods of adjusting transmission intervals for discovery frames. For example, an apparatus may include a wireless communication unit to communicate over a wireless communication medium according to a discovery scheme including a plurality of contention-based discovery windows, the wireless communication unit is to select a discovery window according to a transmission interval, to schedule transmission of a discovery frame for the discovery window, and to adjust the transmission interval based on whether or not the wireless communication medium is observed to be busy during a predefined time period of the discovery window. | 11-06-2014 |
20140330927 | APPARATUS, SYSTEM AND METHOD OF MANAGING AN APPLICATION SERVICE PLATFORM (ASP) SESSION - Some demonstrative embodiments include apparatuses, systems and/or methods of managing an Application Service Platform (ASP) session. For example, an apparatus may include a first ASP to communicate with a second ASP via a wireless Peer-to-Peer (P2P) connection over a P2P link to manage an ASP-session between a first device including the first ASP and a second device including the second ASP. The first ASP may communicate with the second ASP a message to close the ASP-session, the message including a reason field including an indication of a reason for closing the ASP-session. | 11-06-2014 |
20140334464 | APPARATUS, SYSTEM AND METHOD OF SETTING UP AN APPLICATION SERVICE PLATFORM (ASP) PEER TO PEER (P2P) GROUP - Some demonstrative embodiments include apparatuses, systems and/or methods of setting up an Application Service Platform (ASP) Peer-to-Peer (P2P) persistent group. For example, an apparatus may include a first ASP to communicate with a second ASP to setup one or more ASP-P2P groups over a wireless communication link, the first ASP is to form each ASP-P2P group only as an ASP-P2P persistent group extendable over a plurality of distinct sessions, the first ASP is to store credentials of the ASP-P2P persistent group for use during the sessions. | 11-13-2014 |
20140341120 | WIRELESS STATION AND METHOD FOR MANAGING A MULTI-BAND SESSION IN WI-FI DIRECT SERVICES - Embodiments of a method for managing a multi-band Wi-Fi Direct Services session are generally described herein. In some embodiments, the method negotiates the session with a wireless communication station over a first frequency band. The negotiation includes transmitting application programming interface (API) parameters to the wireless communication station that includes parameters for a second frequency band and a channel associated with the second frequency band. | 11-20-2014 |
20140351444 | SYSTEMS AND METHODS FOR ENABLING SERVICE INTEROPERABILITY FUNCTIONALITY FOR WIFI DIRECT DEVICES CONNECTED TO A NETWORK VIA A WIRELESS ACCESS POINT - Certain embodiments herein are directed to enabling service interoperability functionality for wireless fidelity (WiFi) Direct devices connected to a network via a wireless access point. A WiFi Direct device may identify various other WiFi Direct devices on a WiFi network for performing a requested service, such as printing content or displaying content to a screen. In so doing, the device may share information associated with an access point to which the device is connected with the other devices, which may also share information associated with an access point to which they are connected. In this way, WiFi Direct devices may discover their connectivity with respect to other devices to utilize a broader array of connection options for implementing a desired service, and hence, may leverage application programming interface (API) modules directed at providing service interoperability functionality between software applications and services requested by the software applications. | 11-27-2014 |
20140355585 | TECHNIQUES ENABLING USE OF A WI-FI DIRECT SERVICES (WFDS) APPLICATION SERVICES PLATFORM (ASP) FOR LAYER 2 SERVICES - Techniques are disclosed for using a WI-FI Direct Services (WFDS) Application Services Platform (ASP) for Layer 2 services, by extending a definition of a session in WFDS to include non-IP sessions as well. Techniques are further disclosed for operating an application services platform coordination protocol (ASP-CP) directly over a media access control (MAC) layer. | 12-04-2014 |
20150029933 | METHODS AND ARRANGEMENTS FOR TRAFFIC INDICATION MAPPING IN WIRELESS NETWORKS - Embodiments may implement a new hierarchical data structure for traffic indication mapping to facilitate transmissions for wireless communications devices. Many embodiments comprise MAC sublayer logic to generate and transmit management frames such as beacon frames with a partial virtual bitmap based upon the hierarchical data structure for traffic indication mapping. In some embodiments, the MAC sublayer logic may store the traffic indication map and/or the traffic indication map structure in memory, in logic, or in another manner that facilitates transmission of the frames. Some embodiments may receive, detect, and decode communications with frames comprising the partial virtual bitmap based upon the hierarchical data structure. In some embodiments, indications of buffered data for pages, blocks, sub-blocks, and/or stations may be inverted. In several embodiments, a new association identifier (AID) structure is defined for the new hierarchical data structure for traffic indication mapping. | 01-29-2015 |
20150036567 | WIRELESS DEVICE AND METHOD FOR WIRELESS CHANNEL ACCESS - Disclosed in some examples is a method of channel access by a wireless device in a wireless network by determining whether there is network traffic associated with a preamble of a first type and whether there is network traffic associated with a preamble of a second type, wherein the wireless device is not capable of decoding the preamble of the second type, and wherein determining that there is network work traffic associated with a preamble of the second type includes determining that an energy level of the channel is above a threshold for a period of time, the first and second preamble types being different lengths; and sending a packet with a preamble of the first type, responsive to determining that no network traffic is detected associated with the preamble of the second type or network traffic associated with a preamble of the first type for the period of time. | 02-05-2015 |
