Enhanced activation of primary secondary cell group cell (PSCell)

An apparatus, comprising:

• at least one processor;
• and
• at least one memory comprising computer program code,
• the at least one memory and computer program code being configured, with the at least one processor, to cause the apparatus at least to:
• perform at least one of beam failure detection or radio link monitoring on a deactivated secondary cell;
• receive, from a network node, an activation command for the deactivated secondary cell;
• determine whether the deactivated secondary cell and a transmission configuration indicator (TCI) state are known based on at least one of a status of the beam failure detection or a status of the radio link monitoring of the deactivated secondary cell;
• and
• determine an activation delay for activation of the deactivated secondary cell based on a result of the determination of whether the secondary cell and the TCI are known.

A non-transitory computer readable medium comprising program instructions that, when executed by an apparatus, cause the apparatus to perform at least:

• performing at least one of beam failure detection or radio link monitoring on a deactivated secondary cell;
• receiving, from a network node, an activation command for the deactivated secondary cell;
• determining whether the deactivated secondary cell and a transmission configuration indicator (TCI) state are known based on at least one of a status of the beam failure detection or a status of the radio link monitoring of the deactivated secondary cell;
• and
• determining an activation delay for activation of the deactivated secondary cell based on a result of the determination of whether the secondary cell and the TCI state are known.
