Abstract: A user equipment (UE) is described. The UE includes receiving circuitry configured to receive a radio resource control (RRC) message comprising a first parameter(s) used for configuring a first allocation table and a second allocation table. Each of the first allocation table and the second allocation table are used for defining a time domain allocation for a physical uplink shared channel (PUSCH) transmission. The receiving circuitry is also configured to detect in a UE specific search space, a downlink control information (DCI) format comprising first information used for indicating a row index to the first allocation table or the second allocation table. The DCI format is used for scheduling of the PUSCH. The UE also includes transmitting circuitry configured to perform, based on a detection of the DCI format, the PUSCH transmission based on either of the first allocation table or the second allocation table.

Abstract: A joint scheduling and grouping technique provides uplink throughput maximization for space-division multiple access (SDMA) systems under proportional fairness constraints. In a slow-fading narrowband MIMO multiple access channel (MAC) multiple users, each equipped with multiple transmit antennas, communicate to a receiver equipped with multiple receive antennas. The users are unaware of the channel state information (CSI) whereas the receiver has perfect CSI and employs a successive group decoder (SGD). For an open-loop system, an optimum successive group decoder (OSGD) simultaneously minimizes the common outage probability and the individual outage probability of each user, over all SGDs of permissible decoding complexity. For each channel realization, the OSGD maximizes the error exponent of the decodable set of users. An adaptive SGD retains the outage optimality of the OSGD and minimizes decoding complexity. The SGD yields symmetric capacity gains commensurate with the decoding complexity allowed.
