    摘要： A system and method for inter-cell interference avoidance. A device capable of performing channel estimation is configured to divide a codebook into two sets. A first set of said two sets corresponds to codebook information that will cause an interference in a received signal to be less than a threshold. The device further is configured to send feedback information corresponding to the first or second set, or both. A base station is configured to select a preceding vector or matrix based, in part, on a portion of the feedback information.

    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.
