Abstract: A method is provided in one example embodiment and may include calculating, by one or more of a plurality of small cell radios, one or more sets of candidate power control parameters using a first interference constraint for uplink user equipment (UE) transmissions for UE served by the one or more of the plurality of small cell radios; determining, at a central management entity, whether an average of a sum of an expected interference for UE associated with the plurality of small cell radios violates a second interference constraint for any of the one or more sets of candidate power control parameters; and generating one or more messages for each of the plurality of small cell radios identifying one or more particular sets of power control parameters that provide for meeting the second interference constraint.

Abstract: A method is provided in one example embodiment and may include determining one or more uplink inter cell interference coordination (ICIC) parameters for a plurality of cells based, at least in part, on feedback information associated with the plurality of cells; exchanging interference information between neighboring cells; and scheduling uplink transmissions for user equipment served by the neighboring cells based, at least in part, on the uplink ICIC parameters and the interference information exchanged between neighboring cells. A method is provided in another example embodiment and may include determining a ratio relating a first portion of a frequency spectrum for assigning fractional frequency re-use resources to a second portion of the frequency spectrum for assigning re-use one resources; and updating the ratio relating the first portion and the second portion of the frequency spectrum to optimize throughput rates for the plurality of user equipment across the plurality of cells.

Abstract: An apparatus includes an interference rejection combining module, at least partially implemented in hardware. The interference rejection combining module determines a covariance based on a Hermitian transpose of a signal received on a subcarrier of a symbol that is not a pilot symbol.
