International Classification:

H04W 28/00

US Classification:

370328, 3703953, 714748

Abstract:

Methods and apparatus for setting the connection identifier (CID) mask length of a Hybrid Automatic Repeat-Request (HARQ)-MAP or a SUB-MAP pointer information element (IE) in a compressed downlink map (DL-MAP) of an orthogonal frequency-division multiple access (OFDMA) frame are provided in an effort to reduce the number of false indications in the CID mask, while also striving, as a secondary concern, to reduce the CID mask length. In this manner, an individual mobile station (MS) may not waste processing, battery power, or time interpreting a HARQ-MAP message or a sub downlink/uplink map (SUB-DL-UL-MAP) message that was not intended for this particular MS. For some embodiments where the CID mask length is set to be small, the control overhead (i. e. , the size of the HARQ-MAP or the SUB-MAP pointer IE) may be decreased, and more of the OFDMA frame may be available for data traffic.

US Classification:

725 73, 725 62, 725133, 725141, 725153

Abstract:

In general, this disclosure relates to techniques for transmitting data in a spectrum, and seamlessly switching from one transmission channel to an available channel in the spectrum. One example method comprises identifying, by a device, at least a first channel of a spectrum, transmitting at least one command to a second, different device, wherein the at least one command contains information that allows the second device to determine at least the first identified channel, and transmitting data in at least the first identified channel.

US Classification:

370311, 4553434, 340 732, 713323, 713324

Abstract:

Methods and apparatus for reducing power consumption of a mobile station (MS) during layer 3 (L3) peer-to-peer (P2P) communications employing a request/response message pair are provided. To save power, the MS may enter a power saving mode after transmitting a request message and initiating a timeout timer for the message pair, wherein the power saving mode may have an interval available for receiving the response message and an unavailable interval. The timeout timer may be suspended during the unavailable interval and resumed during the available interval such that the timeout timer is effectively lengthened.

US Classification:

455 301, 455522, 455111, 4551572, 4551581

Abstract:

Transmitting devices facilitate privacy protection of content broadcasted from the transmitting device to a receiving device without the need to modify the receiving device. A transmitting device may be adapted to acquire content, such as audio and/or video data, to be broadcasted by the transmitter for reception and use by a receiving device. A transmission range is selected to define a distance for broadcasting the content from the transmission device for reception and use by a receiving device. A frequency is also selected to be used for broadcasting the content. With the transmission range and frequency selected, the transmitting device may broadcast the content according to the selected transmission range and frequency.

International Classification:

H04W 36/00

US Classification:

455436

Abstract:

Methods and apparatus for notifying a mobile station (MS) of service flow parameters supported by neighbor base stations, such that the MS may select a suitable neighbor base station (BS) candidate (i.e., a target BS) for performing a handover are provided. The notification may occur via handover messages, such as a BS Handover Request (MOB_BSHO-REQ) message or a BS Handover Response (MOB_BSHO-RSP) message, with a Service Level Supported field added, indicating the service flow parameters supported by the neighbor BSs. In this manner, service quality levels of data exchanges may be maintained as an MS is handed over from one BS to another.

Abstract:

In general, this disclosure relates to techniques for transmitting data using one or more identified channels of a spectrum. One example method comprises identifying, with a first communication device, at least one channel currently available in a digital broadcast spectrum, and receiving, with the first communication device, data sent from a second communication device. The method further comprises transmitting the data from the first communication device in the at least one identified channel of the digital broadcast spectrum, wherein the transmitted data complies with a digital broadcast format.
