Claim of US Patent No. 10,342,034

1. A method for reporting cell activation status information for one or more cells to a network at a user equipment (UE) in a wireless communication system, the method comprising:receiving, from the network, a message for reporting the cell activation status information,
wherein the message includes:
first information on a condition for reporting the cell activation status information, and
second information on a reporting type for reporting the cell activation status information, and
wherein the reporting type is one of a conditional reporting or an immediate reporting;
reporting the cell activation status information to the network based on the message,
wherein, if the reporting type is the conditional reporting, the cell activation status information is reported when the condition is met,
wherein, if the reporting type is the immediate reporting, the cell activation status information is reported immediately,
wherein the cell activation status information informs of whether each of the one or more cells is activated or deactivated, and
wherein the one or more cells are configured into a timing advance group (TAG); and
after the cell activation status information is reported to the network, reporting a bitmap information for time alignment timer (TAT) status of the TAG,
wherein, if the TAT of the TAG is running, a field of the bitmap information is set to 1, and
wherein, if the TAT of the TAG is not running, the field of the bitmap information is set to 0.
