1. A User Equipment (UE) in a wireless communication system, the UE comprising:
at least one transceiver,
wherein the at least one transceiver configured to use Carrier Aggregation (CA) based on two New Radio (NR) operating bands,
wherein the two NR operating bands are NR operating bands n41 and n77;
at least one processor; and
at least one computer memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
transmitting, via the at least one transceiver, an uplink signal based on one NR operating band of the two NR operating bands; and
receiving, via the at least one transceiver, a downlink signal based on other NR operating band, different from the one NR operating band, of the two NR operating bands,
wherein Maximum Sensitivity Degradation (MSD) value due to cross band isolation is allowed to a reference sensitivity for receiving the downlink signal based on the other NR operating band,
wherein the MSD value is based on a combination of the one NR operating band, the other NR operating band, and channel bandwidth for the downlink signal, based on that the UE is power class 2 UE, and
wherein the MSD value is 6.5 dB, based on that the one NR operating band is n77, the other NR operating band is n41, and the channel bandwidth for the downlink signal is 10 MHz.
