摘要： The present disclosure relates to uplink cooperative multi-User Equipment (UE) cooperative transmission such as Multiple-Input Multiple-Output (MIMO) transmission. Source data of a source UE that is to be transmitted via uplink cooperative transmission by multiple UEs, is transmitted to at least one cooperative UE over an SL. The source data is associated with an identifier for identifying the UE to the network equipment as a source of the source data. The multiple UEs transmit the source data and the identifier in an uplink direction to the network equipment. The network equipment receives the source data from the multiple UEs in a cooperative transmission such as cooperative MIMO transmission, and obtains the identifier for identifying the source UE as the source of the source data.

摘要： A method and apparatus are provided for a wireless communication system including a base station and at least one user equipment. A Channel Quality Indicator (CQI) table can be generated so that only an index corresponding to the measured CQI needs to be fed back to the base station. The CQI tables proposed herein may be suitable to different channel statistics, different Multiple Input Multiple Output (MIMO) mode and may be optimized based on either performance or implementation complexity. Multiple CQI tables may be formed into one compound CQI table. The CQI tables may be stored at both a base station and user equipment. The base station can select a CQI table from the set of tables. The base station signals the selection of the CQI table to the user equipment and the user equipment feeds back indices from the selected CQI table to the base station.

摘要： Aspects of the invention are directed to a transmit diversity method for use in a wireless terminal having a plurality of antennas and a wireless terminal configured to implement the method. The transmit diversity method includes using a different orthogonal sequence for each antenna, or group of antennas, for transmitting an uplink control channel from a wireless terminal to a base station. A first step of the method involves assigning at least one orthogonal sequence to one or more of the plurality of antennas, each of the plurality of antennas being assigned at least one orthogonal sequence. Once the orthogonal sequence is assigned, a further step involves scrambling a signal to be transmitted on the physical uplink control channel (PUCCH) using the at least one orthogonal sequence for each antenna thereby producing a scrambled PUCCH for transmission by each antenna. The scrambled PUCCH can then be transmitted on the plurality of antennas.
