Abstract: Multi-channel support within single user, multiple user, multiple access, and/or MIMO wireless communications. A processor of the communication device is implemented to process a signal to generate processed signals. Also, the communication device includes multiple inverse discrete fast Fourier transform (IDFT) processors respectively to process the processed signals to generate a signal streams respectively across channels (e.g., a first of the IDFT processors is implemented to process a first processed signal to generate a first signal stream based on a fast Fourier transform (FFT) channelization across a first number of orthogonal frequency division multiplexing (OFDM) tones, and a second of the IDFT processors is implemented to process a second processed signal to generate a second signal stream based on the FFT channelization across a second number of OFDM tones). The communication device also includes communication interface(s) to transmit the signal streams to at least one additional communication device.

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: A wireless communication device (alternatively, device) includes a processor configured to support communications with other wireless communication device(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processor, among other possible circuitries, components, elements, etc. to support communications with other wireless communication device(s) and to generate and process signals for such communications. Different long training fields (LTFs) are designed using different respective binary sequences. The LTFs are designs based on a number of resource units (RUs) and RU sizes associated with a sub-carriers/tone plan. Each RU allocation specifies a respective one or more RUs of one or more RU sizes for a communication channel. The LTFs are designed such that peak to average power ratio (PAPR) of the LTF increases across the RU allocations as size of the one or more RU sizes increases.

Abstract: A wireless communication device (alternatively, device) includes a processor configured to support communications with other wireless communication device(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processor, among other possible circuitries, components, elements, etc. to support communications with other device(s) and to generate and process signals for such communications. A device generates and transmits a resource and association poll frame (ra-poll frame) to other device(s). The contents of ra-poll frame direct which of the other device(s) is authorized to respond to the device (e.g., authorized device(s)) and the manner in which they are authorized to respond. Authorized device(s) transmit responses that may include association request(s) and/or a resource request(s), among other types of communications. The device then generates and transmits acknowledgement(s) (ACK(s)) indicates successful receipt of any responses from the authorized device(s).

Abstract: A wireless communication device is configured to generate frames based on any of a number of different frame formats for transmission to one or more other recipient wireless communication devices. The frame may be implemented to include data intended for two or more recipient devices. The device encodes first data intended for a first recipient device using first one or more coding parameters and encodes second data intended for a second recipient device using second one or more coding parameters. The manner by which the first and second data have been encoded is indicated within one or more other fields within the frames based on the selected frame format. In one example, a single preamble specifies the first and second one or more coding parameters. In another example, an initial preamble and one or more respective sub-preambles specify the first and second one or more coding parameters.

Abstract: A wireless communication device (alternatively, device, WDEV, etc.) includes at least one processing circuitry configured to support communications with other WDEV(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other WDEV(s) and to generate and process signals for such communications. A WDEV generates an orthogonal frequency division multiple access (OFDMA) frame that includes a preamble that specifies allocation and/or non-allocation of at least one resource unit (RU) for a communication channel and transmits the OFDMA frame to at least one other wireless communication device to be processed by the at least one other wireless communication device to determine the allocation of the at least one RU for the communication channel or the non-allocation of the at least one RU for the communication channel.

Abstract: A wireless communication device (alternatively, device, WDEV, etc.) includes a processing circuitry configured to support communications with other WDEV(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other WDEV(s) and to generate and process signals for such communications. A WDEV selects a resource unit (RU) from an orthogonal frequency division multiple access (OFDMA) sub-carrier plan for use in supporting communications with another WDEV. The WDEV transmits a signal to the other WDEV that includes information that specifies the RU that is selected from the OFDMA sub-carrier plan and then supports communications with the other WDEV using the RU that is selected from the OFDMA sub-carrier plan. The OFDMA sub-carrier plan includes multiple OFDMA sub-carrier sub-plans of different sized RUs and null sub-carriers.

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: 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.
