Abstract: PROBLEM TO BE SOLVED: To provide techniques for reducing interference to a non-serving base station (a femto cell) when supporting data transmission on an uplink in a wireless network.SOLUTION: A user equipment (UE) can send a data transmission to a serving base station and can send uplink control information (UCI) to a non-serving base station. The UCI includes pertinent information to allow the non-serving base station to process the data transmission from the UE. The UCI allows the non-serving base station to estimate the interference due to the data transmission from the UE and to cancel the interference at the non-serving base station. The interference cancellation can improve the received signal quality at the non-serving base station. After the interference cancellation, the non-serving base station can process a data transmission from another UE served by the base station.

Abstract: PROBLEM TO BE SOLVED: To provide techniques to facilitate inter-cell interference cancellation in a wireless network.SOLUTION: An RNTI component manages a set of radio network temporary identifiers (RNTIs) for plural pieces of user equipment (UE). The RNTI component determines whether the UE will likely cause interference with a neighboring cell or experience interference from a neighboring cell, based on each attribute of the UE. The RNTI component includes a space splitting component that allocates a first group of the UE subjected to the determination to a first subset of the divided RNTIs. Based on the determination, the set of RNTIs is divided into at least two subsets. An implicit broadcast component can implicitly broadcast the first subset of the RNTIs to facilitate cancellation of interference possibly caused by the first group of the UE.

Abstract: PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate interference measurement and reporting in a network multiple-in-multiple-out (N-MIMO) communication system.SOLUTION: A network device can measure and report interference corresponding to network nodes other than a designated set of nodes. Interference reports can additionally identify dominant interfering nodes, correlation between transmit antennas of the respective nodes, or the like. The interference reports are combined with per-node channel information to manage coordination and scheduling across the respective network nodes. Interference from a network node can be measured by observing reference and/or synchronization signals from the network node. Each non-interfering network node can define null pilot intervals in which transmission is silenced or otherwise reduced. Loading information broadcasted by interfering network nodes can be identified and utilized in connection with interference calculation.
