Title:
METHOD AND APPARATUS FOR BEAM MANAGEMENT FOR MULTI-STREAM TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2019/182429
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. A method of a user equipment (UE) for a beam indication in a wireless communication system is provided. The method comprises receiving, from multiple transmission reception points (TRPs), downlink data transmissions, receiving downlink control information (DCI) that includes a beam indication configuration comprising a one bit-field that indicates multiple transmission configuration indicator (TCI) states, wherein each of the multiple TCI states indicates a quasi-colocation (QCL) configuration for downlink data channels received from the TRPs, determining indices of the multiple TCI states based on the received one bit-field included in the DCI, deriving an association between the multiple TCI states indicated by the one bit-field and a downlink data transmission of each of the TRPs, and receiving, the downlink data transmission from each of the TRPs with the QCL configuration indicated by the derived association.
