Abstract
A method of a user equipment (UE) for a beam indication in a wireless communication system is provided. The method includes receiving, from a base station (BS), downlink control information (DCI) including scheduling information for a data transmission on a downlink data channel, wherein the DCI includes an index of a spatial quasi-co-location (QCL) configuration, comparing a time offset between the data transmission and the DCI with a threshold that is pre-configured at the UE, and calculating a receive (Rx) beam based on the index of the spatial QCL configuration or a pre-configured spatial QCL assumption, receiving the data transmission based on the time offset.
