摘要： A base station includes a transmit path circuitry to transmit an uplink grant in a DCI format to a subscriber station. The base station also includes a receive path circuitry to receive only UCI on a PUSCH from a subscriber station when the uplink grant includes a MCS of an enabled transport block (TB) with a value of 29, or a redundancy version of the PUSCH with a value of 1; a CSI request field with a non-zero value; and a total number of physical resource blocks allocated for the subscriber station, NPRB, with a value less than or equal to a threshold number of physical resource blocks, TPRB. TPRB is based at least partly upon one of a total number of CSI information bits to be transmitted on the PUSCH, Ntotal, and a number of DL CCs reported in a current CSI reporting, NCCs.

摘要： A base station includes a transmit path circuitry to scramble CRC bits of a DCI format using a C-RNTI for dynamic scheduling, and scramble the CRC bits of the DCI format using an SPS C-RNTI for semi-persistent scheduling. If C-RNTI is used, the circuitry generates a downlink transmission grant using the DCI format being a fallback format to indicate a transmit diversity transmission scheme or a single-layer beamforming scheme, and uses the DCI format being a dual-layer beamforming format to indicate a dual-DRS port transmission scheme or a single-DRS port transmission scheme. If SPS C-RNTI is used, the circuitry generates a downlink transmission grant using the DCI format being the fallback format to indicate a single-DRS port transmission scheme, and uses the DCI format being the dual-layer beamforming format to indicate a dual-DRS port transmission scheme or a single-DRS port transmission scheme.

摘要： A base station includes a transmit path circuitry to select one of a first UCI multiplexing method that allows a subscriber station to simultaneously transmit PUSCH and PUCCH and a second UCI multiplexing method that does not allow the subscriber station to simultaneously transmit PUSCH and PUCCH. The transmit path circuitry also transmits a higher layer signal indicating the one selected UCI multiplexing method, and transmits one or more uplink grants. Each of the uplink grants schedules a PUSCH in an UL CC for a subframe n, and each of the uplink grants carries a CQI request. The base station also includes a receive path circuitry to receive an aperiodic CSI report on the PUSCH in the uplink component carrier i when only one of the uplink grants scheduling a PUSCH in an uplink component carrier i carries a CQI request having a value from a set of values.
