    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： Methods, devices and computer program products are provided to improve uplink communications in a wireless communication system. Reference symbols in an uplink transmission radio subframe are time-frequency multiplexed with additional data symbols. The multiplexed data symbols are transmitted in an uplink transmission to another device within the wireless communication network along with non-multiplexed data symbols. The multiplexing operations enable the transmission of additional data symbols without increasing the overhead associated with the transmission of symbols in the radio subframe.

    摘要： Techniques for efficiently multiplexing a reference signal and data on different sets of subcarriers in the same symbol period are described. In one design, a user equipment (UE) performs a discrete Fourier transform (DFT) on a set of modulation symbols for data to obtain data symbols. The UE also obtains reference symbols generated based on a reference signal sequence corresponding to a cyclic shift of a base sequence. The UE maps the reference symbols to a first set of subcarriers and maps the data symbols to a second set of subcarriers. The UE then generates a transmission symbol based on the mapped reference symbols and the mapped data symbols. The UE may also transmit reference signals and data (i) in multiple symbol periods of a slot or a subframe and/or (ii) from multiple antennas using frequency division multiplexing (FDM) or code division multiplexing (CDM).

    摘要： A method for discontinuous transmission (DTX) signaling in a physical uplink shared channel (PUSCH) of a wireless communication system includes puncturing at least a portion of a physical uplink shared channel (PUSCH) at a location that would collide with acknowledgement (ACK)/negative (ACK/NACK) feedback if ACK/NACK feedback is transmitted. The method also includes transmitting DTX symbols in the punctured portion of the PUSCH by a user equipment (UE). The method further includes detecting DTX symbols on the PUSCH by an evolved Node B (eNodeB), indicating the UE is operating according to a DTX signaling mode.

    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： Certain aspects of the present disclosure provide techniques for determining resources for transmission of acknowledgement messages to a user equipment (UE). The techniques involve receiving a plurality of codewords from the UE via an uplink component carrier, and determining at least first and second index pairs identifying resources of a downlink channel to be used for transmitting acknowledgement messages for the received codewords. The first index pair is determined based on a first set of parameters, and the second index pair is determined based on the first set of parameters and a second set of one or more parameters. At least one of the parameters in the second set is a fixed value.
