    Abstract: A method and apparatus for transmitting Channel State Information Reference Symbol (CSI-RS) and data with partial muting of the CSI-RS are proposed. The method includes determining a CSI-RS pattern to be used among CSI-RS pattern candidates, determining a muting pattern for muting some resource elements constituting CSI-RS pattern candidates except for the determined CSI-RS pattern, mapping data symbols and CSI-RS to resource elements in a resource grid with rate patching in consideration of the CSI-RS pattern and muting pattern, and transmitting the data symbols and CSI-RS to a terminal.

    Abstract: A base station includes a transmit path circuitry to transmit an uplink grant in a DCI format to a subscriber station. The base station also includes a receive path circuitry to receive only UCI on a PUSCH from a subscriber station when the uplink grant includes a MCS of an enabled transport block (TB) with a value of 29, or a redundancy version of the PUSCH with a value of 1; a CSI request field with a non-zero value; and a total number of physical resource blocks allocated for the subscriber station, NPRB, with a value less than or equal to a threshold number of physical resource blocks, TPRB. TPRB is based at least partly upon one of a total number of CSI information bits to be transmitted on the PUSCH, Ntotal, and a number of DL CCs reported in a current CSI reporting, NCCs.

    Abstract: Methods and apparatuses are described for the transmission of Scheduling Assignments (SAs) from a base station to User Equipments (UEs) for data reception in the downlink or data transmission in the uplink of a communication system consisting of multiple Component Carriers (CCs). The SAs are separately coded and transmitted using elementary units (Control Channel Elements or CCEs). Locations of CCEs determine whether an SA is intended for a first CC or for a second CC. Further, the location of CCEs for an SA intended for a first CC is used to determine locations of CCEs for an SA intended for a second CC.

    Abstract: A user equipment (UE) in a wireless network having two-dimensional antenna systems performs a method of codebook sampling. The method includes receiving from an eNodeB (eNB) an indication of a restricted subset M of vertical precoding matrices, wherein M is less than a total number of vertical precoding matrices N in a codebook, the codebook comprising a plurality of vertical precoding matrices and horizontal precoding matrices. The method also includes feeding back vertical precoding matrix indicators (V-PMI) to the eNB based on the restricted subset of vertical precoding matrices.

    Abstract: A method and apparatus report channel state information (CSI) feedback of a user equipment (UE) in a coordinated multipoint communication system. The method includes identifying, when downlink transmissions to the UE are configured with at least two CSI subframe subsets, an interference measurement resource within one of the CSI subframe subsets belonging to a CSI reference resource. The method also includes using the identified interference measurement resource to derive an interference measurement. The apparatus includes a controller configured to, when downlink transmissions to the UE are configured with at least two CSI subframe subsets, identify an interference measurement resource within one of the CSI subframe subsets belonging to a CSI reference resource. The controller is configured to use the identified interference measurement resource to derive an interference measurement.
