摘要： Embodiments of a wireless device and method for transmitting a packet comprising one or more orthogonal frequency division multiplexed (OFDM) transmission symbols are generally described herein. In some embodiments, the wireless device may be configured to map data to active tones and map zeroes to nulled tones of a set of OFDM tones to generate an OFDM symbol comprising both the active and the nulled tones. The number of active and nulled tones may be based on a nulling factor. The OFDM symbol may be down-clocked to generate an OFDM transmission symbol for transmission over a reduced transmission bandwidth. Accordingly, low power may be used for very low data rate transmissions, which may be suitable for sensor devices.

摘要： Embodiments of a wireless communication device and method for multi-MCS OFDM transmissions at different transmission power levels are generally described herein. In some embodiments, the wireless communication device may have a multi-MCS OFDM transmitter that is configured to encode data for transmission over two or more RF channels with a single encoding scheme to generate an encoded data stream. The transmitter may segment bits of the encoded data stream into a bit stream for each of the RF channels based on a selected modulation level for each of the two or more RF channels. A separate time-domain multicarrier waveform may be concurrently transmitted on each of the two or more RF channels at a power level that is selected not to exceed a maximum allowable transmit power level for that RF channel. The modulation level for each RF channel may be selected based at least in part on the maximum allowable transmit power level for that RF channel.

For example, a receiver may at least partially process a portion of a wireless communication packet, to determine based on the portion of the communication packet whether the packet is intended to be received by the receiver and, if the packet is not intended to be received by the receiver, to abort processing of a remainder of the communication packet by one or more components of a physical layer of the receiver. Other embodiments are described and claimed.

摘要： Logic for collision mitigation between transmissions of wireless transmitters and receivers operating at different bandwidths. Logic of the receivers may be capable of receiving and detecting signals transmitted at narrower bandwidths. In several embodiments, the receivers comprise a clear channel assessment logic that implements a guard interval (or cyclic prefix) detector to detect transmissions at narrower bandwidths. For instance, a two MegaHertz (MHz) bandwidth receiver may implement a guard interval detector to detect 1 MHz bandwidth signals and a 16M Hz bandwidth receiver may implement logic to detect one or more 1 MHz bandwidth signals and any other combination of, e.g., 1, 2, 4, 8 MHz bandwidth signals. In many embodiments, the guard interval detector may be implemented to detect guard intervals on a channel designated as a primary channel as well as on one or more non-primary channels.
