1. A device comprising:
a transceiver configured with a plurality of Evolved UMTS (Universal Mobile Telecommunications System) Terrestrial Radio Access (E-UTRA) operating bands; and
a processor operably connectable to the transceiver, the processer is configured to:
control the transceiver to transmit an uplink signal via two bands among the plurality of E-UTRA operating bands,
wherein the two bands are bands for carrier aggregation (CA); and
control the transceiver to receive a downlink signal via one or more band from the three bands among the plurality of E-UTRA operating bands,
wherein the three bands are configured for CA,
wherein the plurality of E-UTRA operating bands include E-UTRA operating bands 2, 5, 13, 48, and 66,
wherein the three bands include the two bands,
wherein a pre-configured value of Maximum Sensitivity Degradation (MSD) is applied to a reference sensitivity of the one or more band, and
wherein the pre-configured MSD value is 15.6 dB for receiving the downlink signal via band 2, based on the two bands being band 5 and 48, or
wherein the pre-configured MSD value is 16.6 dB for receiving the downlink signal via band 48, based on the two bands being band 2 and 5, or
wherein the pre-configured MSD value is 15.6 dB for receiving the downlink signal via band 2, based on the two bands being band 13 and 48, or
wherein the pre-configured MSD value is 32 dB for receiving the downlink signal via band 48, based on the two bands being band 2 and 66.
