    摘要: A system and method for inter-cell interference avoidance. A base station is configured to perform interference avoidance. The base station receives feedback information from either a second base station or a subscriber station served by the second base station. The base station selects a codebook vectors or matrices for transmission to subscriber stations based, at least in part, on a portion of the feedback information. The base station is further configured to select which subscriber stations will participate in interference avoidance calculations.

    摘要: A mobile station for use in a wireless network. The mobile station transmits feedback values in a physical uplink control channel (PUCCH) to a base station of the wireless network. The mobile station is operable to transmit to the base station a subband second precoder matrix index (PMI) associated with a particular subband and a subband channel quality indicator (CQI) value associated with the particular subband together in a subframe of the PUCCH.

    摘要: Methods for a User Equipment (UE) to transmit Channel Quality Index (CQI) feedback information, and an indicator in feedback information, to an evolved Node B (eNB) in a wireless communication system, and apparatuses therefore, are provided. A method for a UE to transmit CQI feedback information to eNB in a wireless communication system, includes obtaining one or more Transmission Points Configurations for Coordinated MultiPoint (CoMP) (TPCCs), each TPCC including a unique combination of one or more cells in a CoMP measurement set, estimating a channel for one or more cells in the CoMP measurement set, computing a CQI for each of at least one of the one or more TPCCs, each CQI being computed using one or more estimated channels that correspond to the combination of one or more cells included in a corresponding TPCC, generating CQI feedback information based on the one or more CQIs, and transmitting the CQI feedback information.

    摘要: A base station includes a transmit path circuitry to scramble CRC bits of a DCI format using a C-RNTI for dynamic scheduling, and scramble the CRC bits of the DCI format using an SPS C-RNTI for semi-persistent scheduling. If C-RNTI is used, the circuitry generates a downlink transmission grant using the DCI format being a fallback format to indicate a transmit diversity transmission scheme or a single-layer beamforming scheme, and uses the DCI format being a dual-layer beamforming format to indicate a dual-DRS port transmission scheme or a single-DRS port transmission scheme. If SPS C-RNTI is used, the circuitry generates a downlink transmission grant using the DCI format being the fallback format to indicate a single-DRS port transmission scheme, and uses the DCI format being the dual-layer beamforming format to indicate a dual-DRS port transmission scheme or a single-DRS port transmission scheme.

    摘要: A mobile station for use in a wireless network. The mobile station is operable to transmit feedback values to a base station of the wireless network. The feedback values include a first precoder matrix indicator (PMI1) value and a second precoder matrix indicator (PMI2) value. The mobile station transmits the PMI2 value to the base station in the same subframe as a channel quality indicator (CQI) value. The CQI value may be either a wideband CQI value or a subband CQI value.
