If max SR retransmission then will UE perform CB RACH to source cell or other available better cell?

Hi Experts.

Can you please clarify one thing?

If max SR retransmission is achieved then will UE perform CB RACH to source cell or other available better cell?
Please elaborate the reasons for both the scenarios.

UE shall initiate RACH on the SpCell.

UE actions on reaching max SR retransmissions as per NR MAC specification :point_up_2:

What does SpCell means here?
Is this behaviour in case of CA?
Without CA also it will also initiate RACH to other cell?

Please clarify.

SpCell is the terminology of Dual connectivity.
It is defined as “primary cell of a master or secondary cell group”.

It means initiating RACH on the same cell where SR max retransmission is reached.
