    摘要: A base station is provided. The base station includes transmit path circuitry that generates an uplink grant using an uplink multiple-input multiple-output (MIMO) downlink control information (DCI) format. The uplink MIMO DCI format includes a modulation and coding scheme (MSC) field having an MCS value for each of two transport blocks. The transmit path circuitry transmits the uplink grant to a subscriber station. For a given transport block, a combination of the MCS value corresponding to the transport block and a number positive integer of physical resource blocks allocated to the subscriber station (N_PRB) indicates whether the transport block is disabled.

    摘要: A base station includes a transmit path circuitry to transmit an uplink grant to a subscriber station. The uplink grant indicating a first MCS value for a first codeword transmission and a second MCS value for a second codeword transmission. The base station also includes a receive path circuitry configured to receive a MIMO uplink subframe from the subscriber station, the MIMO uplink subframe having a first subset of layers used for the first codeword transmission and a second subset of layers used for the second codeword transmission. ACK/NACK information and RI information are repeated on both the first and second subsets of layers, and CQI is spatially multiplexed on either the first subset or the second subset of layers. If the first MCS value is different from the second MCS value, the CQI is spatially multiplexed onto the subset of layers having a higher MCS value.

    摘要: In a wireless network that operates according to the Long-Term Evolution Advanced standard, a mobile station determines a number of resource elements to be used for HARQ-ACK (hybrid automatic-repeat-request acknowledgement information) or RI (rank indication) on a MIMO (multiple-input multiple-output) PUSCH (physical uplink shared channel). In an embodiment, the mobile station determines a number O of bits in a payload for HARQ-ACK or RI. When the payload O is within a first range, the mobile station determines a minimum number Qmin of resource elements to be used according to a first equation. When the payload O is within a second range, the mobile station determines the minimum number Qmin of resource elements to be used according to a second equation. The mobile station then determines the number Q′ of resource elements according to Qmin and a third equation.
