Title:
METHOD AND INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2022/085663
Kind Code:
A1
Abstract:
A method to be used for a terminal device that communicates with a base station device, said method comprising a step for receiving, from the base station device, a first RRC message containing a parameter relating to a first cell group, and a step for transmitting a random access preamble in a SpCell of the first cell group on the basis of the reception of the first RRC message, wherein the random access preamble is transmitted in the SpCell on the basis of the fact that the first RRC message contains first information and that a time alignment timer in a primary TA group of the first cell group is not running.
