Maximum sensitivity degradation for carrier aggregation

A method performed by a device operating in a wireless communication system, the method comprising:

• transmitting an uplink signal via two bands among a plurality of Evolved UMTS (Universal Mobile Telecommunications System) Terrestrial Radio Access (E-UTRA) operating bands,
• wherein the device is configured with the plurality of E-UTRA operating bands;
• and
• receiving a downlink signal via three bands among the plurality of E-UTRA operating bands,
• wherein the three bands include at least an E-UTRA operating band 2 and the two bands,
• wherein the two bands include two of E-UTRA operating bands 13, 48, and 66,
• wherein the three bands and the two bands are configured for CA (Carrier Aggregation),
• wherein a MSD (Maximum Sensitivity Degradation) value is applied to a reference sensitivity for receiving the downlink signal based on the E-UTRA operating band 2, and
• wherein the MSD value is 28.3 dB, based on that the two bands are E-UTRA operating bands 48 and 66.

A device adapted to operate in a wireless system, the device comprising:

• a transceiver;
• 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 transceiver, an uplink signal via two bands among a plurality of Evolved UMTS (Universal Mobile Telecommunications System) Terrestrial Radio Access (E-UTRA) operating bands;
• and
• receiving, via the transceiver, a downlink signal via three bands among the plurality of E-UTRA operating bands,
• wherein the three bands include at least an E-UTRA operating band 2 and the two bands,
• wherein the two bands include two of E-UTRA operating bands 13, 48, and 66,
• wherein the three bands and the two bands are configured for CA (Carrier Aggregation),
• wherein a MSD (Maximum Sensitivity Degradation) value is applied to a reference sensitivity for receiving the downlink signal based on the E-UTRA operating band 2, and
• wherein the MSD value is 6.2 dB, based on that the two bands are E-UTRA operating bands 13 and 66.
