Abstract: A wireless communication device includes communication interface configured to receive and transmit signals and a processor configured to generate and process such signals. The communication interface of the wireless communication device is configured to receive a first signal from a first other wireless communication device, and the processor of the wireless communication device is configured to process the first signal to determine one or more concurrent transmission parameters. The processor of the wireless communication device is configured to generate the second signal based on the one or more concurrent transmission parameters and direct the communication interface to transmit the second signal to a second other wireless communication device during receipt of the first signal from the first other wireless communication device. The wireless communication device may be configured to make such concurrent transmissions based on one or more considerations such as the power level of the first signal.

Abstract: Selective processing of one or more packets to be transmitted from a wireless communication device to another wireless communication device is effective to reduce the peak to average power ratio (PAPR) of the transmission. The one or more packets are transmitted via two or more sub-bands of an available transmission medium. The number of coefficients or factors within that sequence corresponds to the number of sub-bands via which the one or more packets are to be transmitted. Also, a phase ramp or time-domain cyclic shift may be added to one or more of the packets after having undergone multiplication by one of the coefficients or factors within the sequence.

Abstract: Frame formatting for communications within single user, multiple user, multiple access, and/or MIMO wireless communications. A signal is processed within a communication device using at least two respective downclocking ratios (e.g., a first downclocking ratio applied to a first portion of the signal such as a frame or packet extracted there from, a second downclocking ratio applied to a second portion of the signal). Alternatively, a signal is divided into more than two respective portions, and different respective downclocking ratios are applied to those different respective portions (e.g., a first downclocking ratio applied to a first portion of the signal, and so on up to an n-th downclocking ratio applied to an n-th portion of the signal). Some implementations apply a singular or common downclocking ratio to more than one portion of the signal (which may be contiguous/adjacent or non-contiguous/non-adjacent within the signal).

Abstract: Downclocking and/or adaptive sub-carriers for single user, multiple user, multiple access, and/or MIMO wireless communications. Communication device operation within a wireless local area network (WLAN/WiFi) is effectuated in the frequency spectra typically associated with television broadcast channels. Operation is made on a secondary non-interfering basis to such television broadcast channels. Any desired channel bandwidth (e.g., 6 MHz, 7 MHz, 8 MHz, etc.) may be employed. Adaptation with respect to the number of data sub-carriers within different respective packets may be made in accordance with two or more respective operational modes. For example, modification of the number of data sub-carriers in different respective packets may be made to increase the signal bandwidth from a first band was to a second bandwidth. Also, appropriate frequency down-clocking of a first channel bandwidth may be performed to generate the desired channel bandwidth to be employed within an available television broadcast channel bandwidth.

Abstract: A wireless communication device includes circuitry and capability to perform carrier frequency offset (CFO) estimation based on signals received from one or more other wireless communication devices. In an orthogonal frequency division multiple access (OFDMA) implementation, the wireless communication device receives two or more OFDMA symbols from first and second other wireless communication devices that include data and a copy/repeat of that data from each of the respective first and second other wireless communication devices within specified one or more sub-carriers. The sub-carrier assignment for the first and second other wireless communication devices is made such that the first wireless communication device transmits first data and the copy of that first data using a first at least one sub-carrier, and the second wireless communication device transmits second data and the copy of that second data using a second at least one sub-carrier.

Abstract: A wireless communication device includes a communication interface and a processor that operate to generate a first transmission stream by processing first information based on first parameter(s) and a second transmission stream by processing second information based on second parameter(s). In some examples, the second at least one parameter is relatively less robust than the first at least one parameter, and the second information augments the first information when combined with the first information. The wireless communication device then transmits the first transmission stream and the second transmission stream to at least one other wireless communication device. Examples of such parameters include forward error correction (FEC) code, error correction code (ECC), modulation coding set (MCS), modulation type including a mapping of constellation points arranged in a constellation, power (e.g., transmit (TX) power), orthogonal frequency division multiplexing (OFDM) configuration, and/or a multiple-input-multiple-output (MIMO) configuration.

Abstract: A communication device's processor generates an OFDMA packet that includes different information for different recipient devices. The processor transmits, via a communication interface, different portions of the OFDMA packet via different channels. Initially, the processor transmits a first at least one field of the OFDMA packet intended for a first recipient device via the first channel. Then, the processor transmits a second at least one field of the OFDMA packet intended for the first recipient device via the first channel while simultaneously transmitting at least one other field of the OFDMA packet intended for a second recipient device via a second channel. This staggered transmission of different portions of the OFDMA packet via different channels allows a recipient device to classify different portions of the OFDMA packet and to determine which portions are intended for that recipient device.
