Document Type and Number:
WIPO Patent Application WO/2018/182241
Kind Code:
A1
Abstract:
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Methods and apparatuses for channel state information (CSI) acquisition with downlink (DL) and uplink (UL) reference signals (RSs). A UE apparatus includes a transceiver and a processor operably connected to the transceiver. The transceiver is configured to receive (i) configuration information for a CSI-RS and a sounding reference signal (SRS) and (ii) downlink control information (DCI) that includes a DCI field for an aperiodic SRS transmission request. The processor is configured to decode the configuration information and the DCI with the aperiodic SRS transmission request. The transceiver is further configured to receive the CSI-RS and transmit the SRS. The SRS corresponds to a higher-layer configured SRS resource and a number of configured SRS resources is more than one.
