Abstract: A device for coordinating frequency division multiplexing transmissions over a shared transmission medium may include a processor circuit configured to receive bandwidth requests from devices for transmissions over the shared transmission medium during a time period. A first bandwidth request may correspond to a point-to-multipoint transmission over the shared transmission medium. The processor circuit may be further configured to schedule bandwidth allocations on the shared transmission medium for the time period based at least in part on the bandwidth requests, where a first bandwidth allocation that corresponds to the first point-to-multipoint transmission is scheduled during the time period prior to other bandwidth allocations. The processor circuit may be further configured to transmit, over the shared transmission medium, an indication of the bandwidth allocations.

Abstract: A communication device (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. The device receives a ranging instruction signal, which includes an initial power and at least one power step, from another device. The device processes the ranging instruction generates a first ranging signal based on the initial power. The device then transmits the first ranging signal to the another device. When a ranging response to the first ranging signal is received from the another device, the device determines that the device is successfully ranged to the another device. Alternatively, when no ranging response is received, the device generates a second ranging signal based on the initial power and the at least one power step and transmit the second ranging signal to the another device.

Abstract: A communication device is configured to communicate coded information to other communication device(s). The communication device uses NCPs to indicate locations of codewords within signal(s) transmitted to the other communication device(s). The communication device is configured to encode NCP(s) using an FEC code to generate coded NCP(s) and also to encode the NCP(s) using a cyclic redundancy check (CRC) code to generate NCP CRC bits. The communication device is also configured to encode the NCP CRC bits using the FEC code to generate coded NCP CRC bits. The communication device is then configured to generate OFDM or OFDMA symbol(s) include the coded NCP(s) and the coded NCP CRC bits to indicate beginnings of codeword(s) within at least one of the OFDM symbol(s) and/or additional OFDM symbol(s). The communication device is also configured to transmit the OFDM or OFDMA symbols to another communication device via a communication interface of the communication device.

Abstract: A communication device includes a communication interface, a number of variable power amplifiers (VPAs), and a processor. Some of the VPAs are configured to process analog signals to generate processed analog signals (e.g., each VPA configured to process one of the analog signals to generate one of the processed analog signals based on a respective VPA control signal). A composite VPA processes a summation of the processed analog signals, which are generated by certain of the VPA, to generate a processed composite signal based on a composite VPA control signal. The processor generates the a first, a second, and a composite VPA control signals based, at least in part, on configuration information from another communication device via the communication interface. The processor may be configured to consider other information as well, such as locally generated information (within the communication device), operational history, current operating conditions, etc.
