Abstract: Provided are methods and apparatus for selecting a communication channel. The methods and apparatus select a channel having the least interference and minimize a number of different channels in use. For example, a method for selecting a communication channel includes measuring a transmission characteristic for each channel in a plurality of channels to create a transmission characteristic measurement for each channel. The method also includes receiving, from at least one neighboring access point, data indicating the neighboring access point uses a channel in the plurality of channels. A utility value for each channel in the plurality of channels is calculated by weighting, based on the number of the neighboring access points using each channel in the plurality of channels, the transmission characteristic measurement for each channel in the plurality of channels. Further, the channel having the highest or the lowest utility value is chosen as the communication channel.

Abstract: Provided are methods and apparatus for selecting a channel to use for communicating. The methods and apparatus select a channel having the least interference and minimize a number of different channels in use. For example, a provided method includes calculating a utility value for each channel in a plurality of channels by weighting, based on a number of the neighborhood small cells (NSC) using each channel in the plurality of channels, both a respective modified non-NSC received signal strength indication (RSSI) and a respective modified reference signal received power (RSRP). The non-NSC RSSI is calculated by subtracting a respective RSRP from a total RSSI. The respective modified RSRP for each channel in the plurality of channels is calculated by applying the respective RSRP to a cumulative distribution function. The channel having the highest or the lowest utility value is chosen as the channel to use for the communicating.

Abstract: A base station includes a base unit and a plurality of remote antenna units (RAUs). Each of the RAUs includes a physical layer circuit (PHY). The PHYs are configured to each use the same physical layer identifier, but each PHY includes its own hardware for supporting users in the coverage area of that PHY. The base unit controls resource allocation for the RAUs to increase the capacity of the base station and/or reduce interference between PHYs.
