    摘要: Certain aspects of the present disclosure propose methods and apparatus for utilizing unused Multimedia Broadcast over a Single Frequency Network (MBSFN) subframes for unicast transmissions. The proposed methods include efficient cyclic prefix (CP) and MBSFN frame structure design, and an optimized subframe/carrier bundling window design for hybrid automatic repeat request (HARQ) feedback in presence of the MBSFN subframes.

    摘要: Techniques for transmitting data with transmit diversity for single-carrier frequency division multiple access (SC-FDMA) are described. In one design, a transmitter (e.g., a UE) may form a first symbol vector including first and second modulation symbol sequences. The transmitter may also form a second symbol vector including third and fourth modulation symbol sequences, which may be generated based on the second and first modulation symbol sequences, respectively. Each symbol vector may further include a cyclic prefix and possibly a cyclic postfix for each modulation symbol sequence. The transmitter may generate a first SC-FDMA symbol based on the first symbol vector and a second SC-FDMA symbol based on the second symbol vector. The transmitter may transmit the first and second SC-FDMA symbols from two transmit antennas in a single SC-FDMA symbol period to achieve transmit diversity.

    摘要: Methods and apparatus for performing radio resource management (RRM) measurements in a heterogeneous network (HetNet) are provided in an effort to prevent failure of RRM measurement procedures in a dominant interference scenario. Several alternatives are provided for determining particular resources (e.g., subframes) to use for performing the RRM measurements, wherein the particular resources are based on cooperative resource partitioning between cells of the HetNet, wherein the cells may be of different types (e.g., macro, pico, or femto cells). These alternatives include, for example: (1) intra-frequency or intra-RAT (radio access technology) alternatives, which may involve transmitting resource partitioning information (RPI) in or deriving non-serving cell RPI based on the serving cell's RPI, as well as (2) inter-frequency or inter-RAT alternatives, where the RRM measurements may be performed during a measurement gap.

    摘要: A method, an apparatus, and a computer program product for wireless communication are provided in which a first message to reconfigure an uplink transmission mode of a user equipment (UE) from a first uplink transmission mode to a second uplink transmission mode is transmitted. Further, a reconfiguration scheme to assure at least one of two or more second messages are recognizable by the UE during a transition period after transmission of the first message is implemented. In another example, a UE and eNB may be equipped to respectively transmit and receive a first message to reconfigure a SRS mode used by a UE. In such an aspect the first message may respectively indicate and be used to determine an SRS transmission port specified in a field capable of indicating a number of SRS transmission ports that is greater than a number of physical UE antenna ports.
