Abstract: An apparatus comprises: a first plurality of first radio frequency chains; a second plurality of second radio frequency chains, the first radio frequency chains being configured to produce wider side-band emissions than the second radio frequency chains; at least one antenna array comprising antenna elements, each of a first plurality of the antenna elements being coupled with a corresponding one of the first plurality of first radio frequency chains, the first plurality of first radio frequency chains being configured to cause transmissions predominately in a first band within a channel, each of a second plurality of the antenna elements being coupled with a corresponding one of the second plurality of second radio frequency chains, the second plurality of second radio frequency chains being configured to cause transmissions predominately in at least one second band within the channel.

Abstract: A first channel correlation is calculated for each pair of access terminals in a population of access terminals. A particular pair of access terminals is identified from the population of access terminals based on the first channel correlations. The population of access terminals includes a first access terminal of the particular pair of access terminals, a second access terminal of the particular pair of access terminals, and at least one remaining access terminal from the population of access terminals. A second channel correlation is calculated between the first access terminal and each of the at least one remaining access terminal. A third channel correlation is calculated between the second access terminal and each of the at least one remaining access terminal. One of the first access terminal and the second access terminal is selected to drop from service based on the second channel correlations and the third channel correlations.
