    摘要: A precoding scheme to accommodate user equipment (UEs) having higher Doppler speeds. In such transmission schemes, a different precoding matrix is applied to each orthogonal frequency division multiplex (OFDM) symbol in the transmission stream. Additionally, a downlink control message format is defined to handle assignment of multiple different transmission schemes using the same message format. The downlink control message format includes a control element in one of the message fields along with a set of parameters specifically applicable to the assigned transmission scheme. Based on the value of this control element, the UE sets the specific transmission scheme and determines a set of interpretation rules uniquely associated with that transmission scheme. Using the interpretation rules, the UE is able to read the set of parameters as applied to the selected transmission scheme.

    摘要: Techniques for sending control information relating to multiple downlink carriers and data on a single uplink carrier are described. A user equipment (UE) may be scheduled to transmit on a designated uplink carrier. The UE can multiplex control information for multiple downlink carriers with data for transmission on the uplink carrier in a same subframe. Multiplexing may be performed according to a type of the control information and/or an ordering, priority, or association of the downlink carriers. The UE can selectively encode the control information separately for each downlink carrier and/or jointly across downlink carriers. The control information may be mapped to a single layer or multiple layers of a data channel. The UE may send the multiplexed control information and data on the data channel in the subframe while maintaining a single-carrier waveform.

    摘要: A method includes receiving a cross-subframe assignment in a first subframe, targeting a second subframe in which a transmission power control (TPC) command is to be applied. The method may also include adjusting transmit power in accordance with the TPC command during a third subframe, a predefined number of subframes after the first subframe. Another method includes receiving a cross-subframe assignment in a first subframe. The cross-subframe assignment targets a second subframe in which a first TPC command is to be applied. The method may also include receiving a nominal grant in the first subframe that targets an identified subframe to which a second TPC command is to be applied. The method may also include adjusting the transmit power according to the first TPC command, the second TPC command or a function of the first TPC command and the second TPC command during the second subframe or the identified subframe.

    摘要: A method of wireless communication includes determining a number of symbols for uplink control information (UCI) on each of a plurality of layers, multiplexing symbols for the UCI with data on multiple layers such that the symbols are time aligned across the layers, and sending the multiplexed symbols on the multiple layers on uplink. In some designs, the number of symbols for the UCI may be determined based on a spectral resource parameter.

    摘要: Power adjustment in the user equipment (UE) includes adjusting the transmission power level for each of multiple transport blocks based on the spectral efficiency associated with the transport block. The UE receives a scheduled transport format parameter for each of multiple transport blocks to be transmitted. Based on those scheduled transport format parameters, the UE determines a transmit power level adjustment for each transport block. The UE will adjust the power according to the determined transmit power level adjustment and transmit each transport block using the adjusted power level.
