Systems and methods of decoding data streams and conserving power are described. In some embodiments, a stream of data containing audio and other data is divided into a plurality of timeslots. A first timeslot of the plurality of timeslots is allocated to a first service. A grant allocation message which indicates a location of the first timeslot allocated to the first service is generated. The grant allocation message and the plurality of timeslots are transmitted to a receiver. The transmission system and receiver may be compatible with NRSC-5. The receiver may receive and decode the grant allocation message to identify OFDM symbols that carry information regarding the first service. The receiver may also receive the plurality of timeslots. The receiver may set a power mode of a component during OFDM symbols that indicate a status of the first service.

A method and apparatus for a combined rate and transmission (TX) antenna selection mechanism are described. In one embodiment, the method includes switching between TX antenna combination during a high throughput (HTP) burst transmission of, for example, a physical layer (PHY) aggregated packet. In one embodiment, switching between TX antenna pairs of various combinations of two out of three antennas is performed during the HTP burst transmission. Following the HTP burst transmission, in one embodiment, a block acknowledgement (ACK) is received regarding the HTP burst transmission. In one embodiment, the block ACK is analyzed to select a TX antenna combination. In one embodiment, a TX antenna combination having a lowest packet error rate (PER) is selected according to the block ACK. Other embodiments are described and claimed.

Methods and apparatus for providing an extended-local area system based on short messaging service

Systems and methods for conserving power in a receiver device are provided. In exemplary embodiments, a receiver device comprises a tuner configured to receive a transmitted signal, at least one analog-to-digital converter (ADC), and a digital signal processing hardware comprising a control logic. The exemplary control logic is configured to determine if a symbol within the transmitted signal belongs to an erasure interval, and generate a control signal to configure a receiver device component to conserve power based on the determination.

A method of operation in a communications node is disclosed. The method of operation includes the communications node scanning a plurality of channels simultaneously during a period of time, with the communications node selecting for signal processing a first signal, in a first channel in the plurality of channels, in a first sub-period of time in the period of time. The method of operation includes the communications node selecting for signal processing a second signal, in a second channel in the plurality of channels, in a second sub-period of time in the period of time. Embodiments of the present invention include but are not limited to communications nodes and devices, subsystems, and systems equipped to operate in the above described manner.

Embodiments of multicarrier receiver and method for beamforming using rate-dependent feedback in a wireless network are generally described herein. Other embodiments may be described and claimed. In some embodiments, decimated beamforming matrices are generated for groups of two or more subcarriers and provided to a multicarrier transmitter. The number of subcarriers in a group may be based on a receive data rate. The multicarrier transmitter uses the decimated beamforming matrices to beamform signals for transmission to the multicarrier receiver.
