Abstract
Systems and methods for TCI state activation and codepoint to TCI state mapping are provided. A method performed by a wireless device for activating TCI states includes one or more of: being configured to monitor a plurality of DCI formats with the TCI field for PDSCH reception; receiving a single MAC CE to activate TCI states and map activated TCI states to the TCI field codepoints of the DCI formats; and receiving separate MAC CEs to activate TCI states and map activated TCI states to the TCI field codepoints of each of the plurality of DCI formats. As such, TCI states for downlink scheduling can be more flexibly chosen for each DCI format by using separate MAC CEs. Additionally, default TCI state definitions might be provided when state activation and state to TCI field codepoint mapping to multiple DCI formats are provided by either a single or different MAC CEs.
