    摘要: A user equipment (UE) is configured for carrier aggregation in a wireless communication system. The UE selects control information to be transmitted in an uplink control channel format in a component carrier of two or more component carriers, where the control information includes information types associated with different information reliability requirements. The UE generates an open-loop power control parameter and/or a closed-loop power control parameter based on the information types. The UE transmits the control information in the uplink control channel format at a power level determined by the open-loop power control parameter and/or the closed-loop power control parameter.

    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.

    摘要: Techniques for transmitting data from multiple transmit antennas using space orthogonal resource transmit diversity (SORTD) are described. For the SORTD scheme, a different orthogonal resource may be assigned to each transmit antenna. Data may be sent from the multiple transmit antennas using multiple orthogonal resources. In one design, a UE may process at least one information bit (e.g., with joint or independent coding) to obtain first and second sets of at least one modulation symbol. The UE may process the first set of modulation symbol(s) for transmission from the first transmit antenna using a first orthogonal resource. The UE may process the second set of modulation symbol(s) for transmission from the second transmit antenna using a second orthogonal resource. Each orthogonal resource may include a different reference signal sequence or a different set of reference signal sequence and orthogonal sequence.

    摘要: Systems and methodologies are described that facilitate cycling through precoders for transmitting wireless network communications in a time domain. The precoders can be cycled according to a precoder sequence for each data symbol transmission. When the last precoder is selected the cycle can begin again, a new precoder sequence can be received or defined, and/or the like. A precoder sequence related to a subset of precoders present in a wireless device can be defined sequentially, cyclically shifted according to an identifier or one or more communications parameters, randomly, pseudo-randomly according to an identifier or one or more communications parameters, and/or the like. In addition, the precoder sequence can be utilized to select a precoder for one or more retransmissions. Such cycling of precoders can increase transmit diversity.

    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.

    摘要: Techniques for acknowledging data transmissions in a multi-carrier wireless communication network are disclosed. In some aspects, a user equipment (UE) receives a data transmission on at least one component carrier (CC) in a plurality of configured CCs. The UE determines acknowledgement/negative acknowledgement (ACK/NACK) information for the data transmission and determines an uplink channel for sending the ACK/NACK information. When the ACK/NACK information is sent on a physical uplink control channel (PUCCH), the UE may perform power control based on which CCs in the plurality of configured CCs data is received. When the ACK/NACK information is sent on a physical uplink shared channel (PUSCH), the UE may determine a number of resource elements based on its CC configuration.

    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.
