  • Method and system for indicating method used to scramble dedicated reference signals
    Patent number: 9585136
    Abstract: 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.
