    摘要: Systems and methodologies are described that facilitate dynamic selection of a random access channel configuration. Typically, a single random access channel configuration is utilized throughout a cell; however, the configuration employed, while appropriate for some mobile devices within the cell, can introduce unnecessary overhead for other mobile devices. A mobile device can measure a characteristic of a radio link between the mobile device and a base station. The measurement can be compared to a set of thresholds provided by the base station. Based upon the comparison, a random access channel configuration can be selected from a set of formats. The selected configuration can be utilized to initiate random access procedures.

    摘要: Techniques for handling inconsistent control information in a wireless communication system are described. In an aspect, inconsistent control information is handled in different manners for the downlink and uplink. In one design, a user equipment (UE) receives a first grant with first control information for a first data transmission and also receives a second grant with second control information for a second data transmission. The UE determines that the second control information is inconsistent with the first control information, e.g., due to the two grants conveying different transport block sizes. The UE determines whether to retain or discard the second grant based on whether the two grants are for data transmissions on the downlink or uplink. In one design, the UE retains the second grant if the two grants are for data transmissions on the downlink and discards the second grant if the two grants are for data transmissions on the uplink.

    摘要: Techniques for computing and reporting channel quality indication (CQI) are described. In an aspect, a plurality of CQI computation methods may be supported, and each CQI computation method may indicate how CQI should be computed. One CQI computation method may be selected for use. CQI may then be computed and reported in accordance with the selected CQI computation method. In an exemplary design, a user equipment (UE) may obtain a selected method for computing CQI, which may be chosen based on the UE capability and/or other factors. The selected method may specify (i) CQI computation for a specific codeword among a plurality of codewords or (ii) CQI computation by averaging signal quality across a plurality of layers used for transmission. The UE may compute CQI in accordance with the selected method, send the CQI to a base station, and receive data sent by the base station based on the CQI.

    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: Techniques for supporting data transmission with little or no control overhead are described. In an aspect, data may be sent based on a hybrid scheme that utilizes a combination of group hopping for transmissions of new packets and static grouping for retransmissions of pending packets. For the hybrid scheme, a user equipment (UE) may be assigned different resource blocks in different transmission intervals based on a hopping pattern. The first transmission of new packets may be sent on resource blocks determined based on the hopping pattern. Retransmissions of each packet, if any, may be sent on the resource block used for the first transmission of the packet. The UE may perform blind decoding to recover packets sent to the UE. In another aspect, semi-static group assignment may be used, and the UE may be assigned a group of resource blocks that may change periodically or based on trigger events.

    摘要: Aspects of the present disclosure relate to techniques for non-codebook based uplink (UL) transmission. In some cases, a user equipment (UE) may signal, to a network entity, capability information of the UE for non-codebook uplink transmissions.

The UE may then transmit the SRSs using the associated precoding candidates.
