  • Publication number: 20160309476
    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.

  • Publication number: 20160156430
    Abstract: The present disclosure provides a fine-grained link adaptation mechanism that allows for link adaptation at a resource block granularity. To this end, the fine-grained link adaptation mechanism can determine the effective signal-to-interference-plus-noise ratio for individual user equipment in a particular cell at the resource block granularity. This way, the transmitter can use the effective signal-to-interference-plus-noise ratio to adapt the modulation and coding scheme at the resource block granularity. The fine-grained link adaptation mechanism can be introduced to a long term evolution (LTE) network without substantial redesign of the LTE network.

  • Publication number: 20160028516
    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.
