    • 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.

    • A subscriber station is provided. The subscriber station includes a transmit path circuitry to transmit uplink control information (UCI) in a subframe comprising one or more resource blocks, each resource block comprising S SC-FDM symbols. Each of the S symbols comprises N virtual subcarriers, and each subcarrier of each symbol comprises a resource element. The subscriber station also includes a UCI symbol allocator to allocate a first vector sequence of HARQ-ACK bits to a control region of each of four symbols of a resource block, the control region allocated for HARQ-ACK bits. The UCI symbol allocator also allocates a second vector sequence of HARQ-ACK bits to a control region of a fifth symbol of the resource block when a condition is met. The control region of the fifth symbol can be allocated for rank information (RI) bits.
    • 提供一个用户台。 用户站包括发送路径电路,用于在包括一个或多个资源块的子帧中发送上行链路控制信息(UCI),每个资源块包括S SC-FDM符号。 每个S符号包括N个虚拟子载波,并且每个符号的每个子载波包括资源元素。 用户站还包括UCI符号分配器,用于向资源块的四个符号中的每一个的控制区分配HARQ-ACK比特的第一向量序列,分配给HARQ-ACK比特的控制区。 当满足条件时,UCI符号分配器还将HARQ-ACK比特的第二矢量序列分配给资源块的第五个符号的控制区域。 第五符号的控制区域可以被分配用于等级信息(RI)位。
