EXPLICIT UNIFIED TRANSMISSION CONFIGURATION INDICATOR (TCI) STATE INDEX CONFIGURATION FOR DOWNLINK (DL) TRANSMISSION

Abstract

A method, network node and wireless device (WD) for explicit unified transmission configuration indicator (TCI) state index configuration for downlink (DL) transmissions are disclosed. According to one aspect, a method in a network node includes configuring the WD with a radio resource control (RRC) configuration of at least one transmission configuration indicator (TCI) state pointer, the at least one TCI state pointer being used to indicate an association between at least one scheduled physical downlink shared channel (PDSCH) transmission and at least one joint/downlink TCI state. The method also includes transmitting first and second downlink control information (DCI), the first DCI configured to one of activate and indicate a pair of unified TCI states, the second DCI configured to schedule a first PDSCH and a second PDSCH.
