Method and system for indicating method used to scramble dedicated reference signals
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.
Abstract(Chinese):

基站包括使用C-RNTI对动态调度的DCI格式的CRC比特进行加扰的发送路径电路，以及使用用于半持续调度的SPS C-RNTI对DCI格式的CRC比特进行加扰。 如果使用C-RNTI，则电路使用DCI格式生成下行链路传输许可，该格式是回退格式以指示发射分集传输方案或单层波束成形方案，并且使用作为双层波束成形格式的DCI格式 表示双DRS端口传输方案或单DRS端口传输方案。 如果使用SPS C-RNTI，则电路使用DCI格式作为回退格式生成下行链路传输许可，以指示单DRS端口传输方案，并使用作为双层波束形成格式的DCI格式， DRS端口传输方案或单DRS端口传输方案。
