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 device may include a processor circuit configured to transmit, over a network medium, a request for transmission of a data communication to a first device of a network, and receive, over the network medium, a grant of the request. When the first device is associated with a first security profile, the processor circuit may be configured to encrypt the data communication based at least on a first password associated with the first security profile. When the first device is associated with a second security profile, the processor circuit may be configured to encrypt the data communication based at least on a second password associated with the second security profile. The second password may be associated with a higher password strength than the first password. The processor circuit may be configured to transmit, over the network medium, the encrypted data communication to the first device in response to the grant.

Abstract: A communication device having a Media Access Control (MAC) layer and a physical (PHY) layer may include a first physical channel for transferring at least one packet between the PHY layer and the MAC layer. The communication device may further include a second physical channel for transferring, to a transmitting device, a first table that indicates a number of bits to be loaded onto each of a plurality of tones and a second table that indicates a transmission power for the plurality of tones. The PHY layer may receive the at least one packet from the transmitting device over the plurality of tones and may transfer the at least one packet to the MAC layer via the first physical channel.

Abstract: A device implementing a channel estimation for multi-channel transmissions system may include at least one processor configured to receive a set of signals over a set of channels, wherein each signal of the set of signals includes one of a set of channel estimation sequences. The set of channel estimation sequences may have been selected based at least in part on a signal quality metric, such as a peak-to-average power ratio, associated with a combination of the set of signals. The at least one processor may be further configured to perform a channel estimation for each channel based at least in part on the channel estimation sequence included in the signal received over each channel. In one or more implementations, the set of channel estimation sequences may be selected to minimize the signal quality metric associated with the combination of the plurality of channels.
