    Abstract: A method for mitigating interference in a wireless network includes an eNodeB and/or a UE identifying interference. The eNodeB may identify the interfering TDD configurations based on a downlink signal of a neighboring eNodeB received during an uplink timeslot for a UE associated with the eNodeB. Likewise, the UE may identify an interfering UE based on an uplink signal received during a downlink timeslot for an eNodeB associated with the UE. The eNodeB performs interference management based at least in part on the identified interference.

    Abstract: relatório de retorno baseado em grupos de sinal de referência de informação de estado de canal (csi-rs) em configurações macro / rrh, os sinais de referência de informação de estado de canal (csi-rs) e os sinais de referência de demodulação (dm-rs) podem ser utilizados para dissociar a transmissão de dados e controle. a transmissão de dados (por exemplo, para lte versão 10 e posteriores) pode se basear em csi-rs e dm-rs, enquanto que o controle pode ser recebido a partir de um conjunto diferente de células ou txps via crs. certos aspectos da presente descrição introduzem um quadro de relatório, em que a configuração de células servidoras - dados / txps pode ser efetuada com base em csi-rs. em certos aspectos, um novo conceito de grupos csi-rs, ou seja, um conjunto de portas csi-rs que um ue considera como um grupo para relatório de indicador de matriz de pré-codificação (pmi) / indicador de qualidade do canal (cqi) /indicador de classificação (ri), pode ser definido.

    Abstract: A method for mitigating interference in a wireless network includes an eNodeB and/or a UE identifying interference. The eNodeB may identify the interfering TDD configurations based on a downlink signal of a neighboring eNodeB received during an uplink timeslot for a UE associated with the eNodeB. Likewise the UE may identify an interfering UE based on an uplink signal received during a downlink timeslot for an eNodeB associated with the UE. The eNodeB performs interference management based at least in part on the identified interference. HARQ transmissions are rescheduled from non anchor subframe potentially not common to a set of TDD configurations to anchor subframe common to the set of TDD configurations.

    Abstract: A wireless communication device for sending quantization quality feedback is described. The wireless communication device includes a receiver that receives a signal. The wireless communication device also includes channel estimation circuitry coupled to the receiver. The channel estimation circuitry generates a channel estimate based on the signal. The wireless communication device also includes feedback determination circuitry coupled to the channel estimation circuitry. The feedback determination circuitry generates quantization quality feedback based on the channel estimate. The wireless communication device also includes a transmitter coupled to the feedback determination circuitry. The transmitter transmits the quantization quality feedback.

    Abstract: Certain aspects of the present disclosure provide techniques for measuring interference observed at a CoMP UE caused by neighbor base stations transmitting reference signals. The present disclosure provides a method for wireless communication comprising: determining at a user equipment UE served by at least one base station BS a reference signal RS configuration indicating resources on which one or more neighbor BSs transmit RS or data; estimating interference observed at the UE caused by the neighbor BSs based on RS or data transmitted by the neighbor BSs on the indicated resources; computing a channel state information CSI using said interference estimate; and sending the CSI to the serving BS for use in coordinating transmissions with the neighbor BSs.
