    摘要: Systems and methodologies are described that facilitate performing antenna virtualization in a wireless communication environment. A set of physical transmit antennas can be partitioned into a plurality of groups of physical transmit antennas. Further, a precoding vector for a particular group of physical transmit antennas from the plurality of groups of physical transmit antennas can be formulated. Moreover, the particular group of physical transmit antennas can form a particular virtual antenna. By way of another example, a disparate precoding vector for a disparate group of physical transmit antennas from the plurality of groups of physical transmit antennas can be formulated, and the disparate group of physical transmit antennas can form a disparate virtual antenna. The precoding vector can be applied to a signal for transmission over the particular virtual antenna, and the disparate precoding vector can be applied to a disparate signal for transmission over the disparate virtual antenna.

    摘要: A method, apparatus, and computer program product for wireless communication are provided to receive a downlink grant including a transmission power control (TPC) command and a downlink assignment index (DAI) for an uplink subframe, determine that a value for at least one of the TPC commands is an ACK/NACK resource indicator for an uplink control channel resource based on a value of the DAI, and transmit one or more ACK/NACK bits using the uplink control channel resource. In another example, an eNB may be equipped to transmit a downlink grant including TPC command and DAI for an uplink subframe, wherein the DAI is greater than 1 and the TPC command is replaced with an ACK/NACK resource indicator, and receive a signal including uplink control channel information, where ACK/NACK feedback for one or more downlink subframes associated with the uplink subframe are included in a resource indicated by the resource indicator.

    摘要: Bits for acknowledgement (ACK) and/or negative acknowledgement (NAK) may be allocated based on whether a special subframe configuration in a TDD configuration permits downlink transmission. For carrier aggregation, ACK/NAK bits may be allocated only to special subframes in component carriers (CCs) which permit downlink transmission. Also, for example, ACK/NAK bits may be allocated to all CC special subframes if a single CC is configured to allow downlink transmission on one of its special subframes. ACK/NAK bits may also be allocated to all special subframes.

    摘要: In a wireless communication network that performs Multiple Input Multiple Output (MIMO) communication, uplink power control signals are provided to a user equipment (UE) via a base station signaled power allocation scheme responsive to a determination of whether or not the uplink transmission is in a interference limited condition relative to a neighboring cell.
