    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 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: 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.
