Abstract
The present application relates to devices and components, including apparatus, systems, and methods for transmission configuration indicator switching for non-terrestrial networks.
Claims21
1-27. (canceled)
A method comprising:
- receiving, from a base station (BS), a configuration for a timer associated with transmission configuration indicator (TCI) state switching;
- activating or enabling a TCI state;
- and
- starting the timer based on said activating or enabling the TCI state.
1 more element
An apparatus comprising:
- processor circuitry to:
- receive, from a base station (BS) coupled with a satellite, a list of candidate transmission configuration indicator (TCI) states;
- process an uplink or downlink transmission based on a first TCI state;
- detect a switching event based on a measurement of a user equipment (UE), a preconfigured timestamp, or a position of the satellite;
- and
- switch from the first TCI state to a second TCI state based on the detection of the switching event, the second TCI state selected from the list of candidate TCI states;
- and interface circuitry coupled to the processor circuitry to enable communication.
4 more elements
One or more non-transitory, computer-readable media having instructions that, when executed, cause processor circuitry to:
- generate, for transmission to a user equipment (UE), a configuration for a timer to be used by the UE for transmission configuration indicator (TCI) switching;
- and
- generate, for transmission to the UE, or receive, from the UE, an indication of activating or enabling a TCI state, the activating or enabling the TCI state to trigger starting the timer.
