Abstract:
A first wireless device operating in a wireless network generates a frame and transmits the frame to a second wireless device operating in the wireless network. Generating the frame includes inserting, into a Quality of Service (QoS) field of the frame or into a High Throughput (HT) Control field of the frame, buffer status information for one or more traffic identifiers (TIDs). Generating the frame may also include inserting, into the QoS or HT Control field, an indication whether the buffer status information represents all TIDs active between the first and second wireless device. A first wireless device operating in a wireless network receives a frame from a second wireless device operating in the wireless network, and decodes the frame. Decoding the frame includes determining, using a QoS field of the frame or using a HT Control field of the frame, buffer status information for multiple TIDs.
Abstract:
The present disclosure describes systems and techniques relating to wireless communications. According to an aspect of the described systems and techniques, an apparatus includes circuitry configured to receive a signal representing a wireless communication transmission; and circuitry configured to process the signal to (i) decode a control portion of the wireless communication transmission, (ii) determine from the decoded control portion that a data portion of the wireless communication transmission was successfully decoded previously and acknowledged, and so the wireless communication transmission is an unnecessary retransmission, and (iii) trigger acknowledgement of the wireless communication transmission being successfully decoded, without completing a decode of the data portion of the wireless communication transmission, when the unnecessary retransmission is detected.
Abstract:
A macro wireless communication system includes a base station and a femto access point for communicating with user equipment (UE), such as handset, whereby the UE receives information regarding the network relationships between the base station and the femto access point. A home profile setting may be stored in the UE. When the UE communicates with a femto access point that is identified in the home profile, the UE adapts a neighbor listing provided by the home femto access point. Alternatively, the base station stores a list of the UE and its corresponding home femto access point, along with the neighbor list of the femto access point. When a UE is connected to the base station and that base station is in neighbor list of the UE's home femto access point, a message is sent to the UE to forward an appropriate neighbor list to simplify handovers.
Abstract:
A method for encrypting the content key in a mobile multimedia broadcast service includes that: a content distribution platform transmits a content key of a content flow and a content ID which identifies the content flow to a mobile service management platform; the mobile service management platform obtains a service key according to the content ID of the content flow and encrypts the content key of the content flow with the service key; the mobile service management platform transmits the encrypted content key of the content flow to the content distribution platform. A system for encrypting the content key in the mobile multimedia broadcastservice is provided by the present invention. The present invention can match the content ID of the content flow with the service ID of the multimedia broadcast automatically and avoid the error caused by manual stepping in the system.
Abstract:
A system and method for locating, tracking, and/or monitoring the status of personnel and/or assets (collectively "trackees"), both indoors and outdoors, is provided. Tracking data obtained from any number of sources utilizing any number of tracking methods may be provided as input to a mapping application. The mapping application may generate position estimates for trackees using a suite of mapping tools to make corrections to the tracking data. The mapping application may use information from building data to enhance position estimates. Indoor tracking methods including sensor fusion methods, map matching methods, and map building methods may be implemented to take tracking data from one or more trackees and compute a more accurate tracking estimate for each trackee. Outdoor tracking methods may be implemented to enhance outdoor tracking data by combining tracking estimates such as inertial tracks with magnetic and/or compass data and with GPS.
Abstract:
The present invention offers systems and methods for effective multiple-hop routing, multicasting and media access control for vehicle group communications that employ directional wireless radio technology. Multi-beam optic-wireless media and streamlined operations provide low-overhead communications among vehicles. Systems and methods are provided to maintain a quasi-stationary group of neighboring vehicles, enable high- throughput on-demand switching among multiple vehicles, enable group coding in the vehicle group to achieve higher throughput, and enable dynamic adjustment of link to maintain desirable vehicle group. The proposed solution builds upon the conception of a MAC-free wireless operation and quasi -stationary vehicular switched network to achieve ultra-low-overhead and high-throughput vehicle communications.
Abstract:
A method for automatically configuring a portable device comprises determining a position of the portable device and automatically configuring the portable device based on the determined position.
Abstract:
System and method for improving the use of radio spectrum in transmission of data, according to which the payload information of any known line interface is divided into a plurality of data portions of smaller which are then grouped into packets so as to be subsequently radio transmitted. For transmission of such packets, suitable radio channels are selected. The invention also relates to reception of such radio channels having such packets incorporated therein, wherein the received packets are then transformed into payload information for inputting into corresponding line interfaces.
Abstract:
A location mechanism for a mobile device, in which an electronic communication including a code is received at the mobile device and the code is parsed from within the received electronic communication. The code parsed from within the electronic communication is used to determine whether to classify the received electronic communication as a coded electronic communication, and the received electronic communication is classified as a coded electronic communication based on results of the determination. In response to classification of the electronic communication as a coded electronic communication, a process is initiated that facilitates location of the mobile device. For instance, volume control settings at the mobile device may be overridden and an audible alert at the device may be invoked, and/or a response electronic communication that includes location information indicative of a current location of the communication device may be generated and sent.
