Abstract
A User Equipment is disclosed that determines a default Transmission Configuration Indicator (TCI) state in a wireless communication network in a High-Speed Train environment. The UE determines that wireless communication is being carried out in Frequency Range 2 and receives one or more Core Resource Sets (CORESETs) carrying a Physical Downlink Control Channel (PDCCH) with a Downlink Control Information (DCI); that a time offset between reception by the UE of the DCI and a corresponding Physical Downlink Shared Channel (PDSCH) is less than a predetermined time threshold; that the PDSCH is configured with a Single Frequency Network (SFN) scheme; that an option to enable two default TCI states for the UE is not configured; whether the PDCCH is configured with an SFN scheme; and based on a result of determining whether the PDCCH is configured with an SFN scheme, a default TCI state is determined for PDSCH reception.
