Abstract: Preference-based downlink resource allocation mechanisms for communication systems, such as low earth orbit satellite communication systems, may be implemented as auctions. Unlike allocation methods that do not take channel diversity into consideration, the disclosed methods improve communication efficiency while reducing uplink overhead compared with methods that feedback complete channel state information (CSI). Moreover, the disclosed methods simplify computational complexity and improve scalability compared with optimal allocation, and enable the derivation of implicit CSI from the submitted requests or bids.

Abstract: Systems and methods provide for use of spectrum emission masks to allow for two or more devices to coexist on a common communication bandwidth. The spectrum emission masks may include one, two, or three interior attenuation regions that, when implemented by a transmitting device, significantly reduce the transmission power in the interior attenuation regions. The interior attenuation regions may transmit to interior channels that separate one, two, or three outer channels of a plurality of channels spanning the common communication bandwidth.

Abstract: A method for automatic management of a wireless access point includes (a) changing a minimum modulation coding scheme of the wireless access point from a first minimum modulation coding scheme to a second minimum modulation coding scheme; (b) determining a first change in performance of the wireless access point in response to changing the minimum modulation coding scheme; and (c) in response to the first change in performance of the wireless access point meeting a first threshold condition, continuing to operate the wireless access point in the second minimum modulation coding scheme.
