    Abstract: A user equipment (UE) is configured to determine channel quality information (CQI) in a wireless communication system. The UE includes a processor configured to receive from an eNodeB (eNB) signaling parameters related to a first co-channel precoding matrix indicator (PMI) codebook, determine a second co-channel PMI based on a determined single user PMI (SU-PMI) and the received signaling parameters related to the first co-channel PMI codebook, determine a multi-user CQI (MU-CQI) based on the second co-channel PMI, and transmit the MU-CQI to the eNB.

    Abstract: A mobile station configured to receive transmissions from a two-dimensional array of antennas at a base station is provided. A main processor of the mobile station is configured to estimate first and second channel states and determine a co-phasing scalar component for each of multiple groups of antennas in the array based on the first channel state. The main processor is configured to generate a matrix X that includes a plurality of column vectors selected from a codebook based on the second channel state, generate a matrix P1, wherein the matrix P1 is a block diagonal matrix having the matrix X for each block diagonal element, and generate a matrix P2. The main processor is also configured to transmit to the base station information corresponding to the matrix P1 and to the matrix P2, as well as a CQI that is derived with a precoding matrix P defined by P=P1P2.

    Abstract: A method for transmitting a CSI feedback report to a serving cell comprises for time division duplex, configuring at least one periodic CSI process with a CSI reference source defined by a single downlink subframe n-nCQI—ref, wherein nCQI—ref is a smallest value greater than or equal to a positive integer nCQI—ref—min, such that it corresponds to a valid downlink subframe, wherein nCQI—ref—min varies based on a number of at least one periodic CSI process. A method for CSI feedback reporting to a base station comprises configuring not to accommodate, by a user equipment, the one or more aperiodic CSI requests arrived from a serving cell except a CSI request of CSI processes with lower indexes for each serving cell, wherein a number of the one or more CSI processes with a lower index (es) is determined based on a number of pending CSI reports.

    Abstract: Methods and apparatuses indicate and identify quasi co-located reference signal ports. A method of identifying by a UE includes identifying, from downlink control information, a CSI-RS port that is quasi co-located with a DM-RS port assigned to the UE. The method includes identifying large scale properties for the assigned DM-RS port based on large scale properties for the CSI-RS port. The method includes performing channel estimation and/or time/frequency synchronization using the identified large scale properties for the DM-RS port. Another method for identifying by a UE includes identifying, from downlink control information, a CRS port that is quasi co-located with a CSI-RS port configured for the UE. The method includes identifying large scale properties for the configured CSI-RS port based on large scale properties for the CRS port. The method includes performing channel estimation and/or time/frequency synchronization using the identified large scale properties for the CSI-RS port.
