1. A terminal device, comprising:
at least one processor; and
at least one memory including computer program codes;
the at least one memory and the computer program codes are configured to, with the at least one processor, cause the terminal device at least to:
receive, from a first cell connected to the terminal device, an activation signal to activate a second cell, the second cell being aggregated with the first cell, and the first cell and the second cell belonging to a frequency range 2 (FR2);
determine whether the second cell is known or unknown; and
in response to determining that the second cell is unknown, detect a reference signal transmitted from the second cell by using a spatial receiver (Rx) beamforming of an Rx beam which has been received from the first cell.
