Abstract
Disclosed are a method and device for activating/deactivating a TCI in an mTRP system. The method performed by a UE comprises the steps of: receiving, from a base station, a TCI state activation/deactivation MAC CE indicating activation or deactivation of a TCI state; identifying one or more TRPs indicated by a TRP indicator field included in the TCI state activation/deactivation MAC CE; identifying one or more TCI state IDs associated with the one or more TRPs on the basis of the TCI state ID fields included in the TCI state activation/deactivation MAC CE; and activating or deactivating one or more TCI states having the one or more TCI state IDs.
Claims20
A method of a user equipment (UE), comprising:
- receiving a transmission configuration indicator (TCI) state activation/deactivation medium access control (MAC) control element (CE) from a base station, the TCI state activation/deactivation MAC CE indicating activation or deactivation of TCI state(s);
- identifying one or more transmission and reception points (TRPs) indicated by a TRP indication field included in the TCI state activation/deactivation MAC CE;
- identifying one or more TCI state indexes (IDs) associated with the one or more TRPs, based on TCI state ID fields included in the TCI state activation/deactivation MAC CE;
- and
- activating or deactivating one or more TCI states having the one or more TCI state IDs.
A method of a base station, comprising:
- generating a transmission configuration indicator (TCI) state activation/deactivation medium access control (MAC) control element (CE) including a TRP indication field indicating one or more transmission and reception points (TRPs) and one or more TCI state index (ID) fields associated with the one or more TRPs;
- and
- transmitting the TCI state activation/deactivation MAC CE to a user equipment (UE),
- wherein the TCI state activation/deactivation MAC CE indicates activation or deactivation of one or more TCI states associated with the one or more TRPs.
A user equipment (UE) comprising:
- at least one processor, wherein the at least one processor causes the UE to perform:
- receiving a transmission configuration indicator (TCI) state activation/deactivation medium access control (MAC) control element (CE) from a base station, the TCI state activation/deactivation MAC CE indicating activation or deactivation of TCI state(s);
- identifying one or more transmission and reception points (TRPs) indicated by a TRP indication field included in the TCI state activation/deactivation MAC CE;
- identifying one or more TCI state indexes (IDs) associated with the one or more TRPs, based on TCI state ID fields included in the TCI state activation/deactivation MAC CE;
- and
- activating or deactivating one or more TCI states having the one or more TCI state IDs.
