Abstract

Provided is a method for transmitting and receiving a signal by a terminal supporting dual-connectivity between evolved universal terrestrial radio access (E-UTRA) and new radio (NR). In the method, when the terminal is configured to aggregate at least two carriers and when the at least two carriers include one of E-UTRA operating bands 1, 3, 19, and 21 and at least one of NR operating bands n78 and n79, an uplink center frequency of a first carrier among the at least two carriers is a first value and a downlink center frequency of the first carrier is a second value, a predetermined maximum sensitivity degradation (MSD) is applied to a reference sensitivity used for reception of the downlink signal.

First claim

What is claimed is:

1. A device configured to operate in a wireless system, the device comprising:
a transceiver configured with an Evolved Universal Terrestrial Radio Access (E-UTRA)-New Radio (NR) Dual Connectivity (EN-DC),
wherein the EN-DC is configured to use two bands,
a processor operably connectable to the transceiver,
wherein the processer is configured to:
control the transceiver to receive a downlink signal,
control the transceiver to transmit an uplink signal via the two bands,
wherein a value of Maximum Sensitivity Degradation (MSD) is applied to a reference sensitivity for receiving the downlink signal,
wherein the value of the MSD is pre-configured for a combination of bands 21 and n79,
wherein the value of the MSD is 18.4 dB for band 21 based on the combination of bands 21 and n79.

2. The device of claim 1 ,
wherein for the combination of bands 21 and n79, the band 21 is used for the E-UTRA and the band n79 is used for the NR.

3. A device configured to operate in a wireless system, the device comprising:
a transceiver configured with an Evolved Universal Terrestrial Radio Access (E-UTRA)-New Radio (NR) Dual Connectivity (EN-DC),
wherein the EN-DC is configured to use three bands,
a processor operably connectable to the transceiver,
wherein the processer is configured to:
control the transceiver to receive a downlink signal,
control the transceiver to transmit an uplink signal via at least two bands among the three bands,
wherein a value of Maximum Sensitivity Degradation (MSD) is applied to a reference sensitivity for receiving the downlink signal,
wherein the value of the MSD is pre-configured for a first combination of bands 1, n78 and n79, a second combination of band 3, n78 and n79, a third combination of bands 19, n78 and n79, a fourth combination of bands 21, n78 and n79.

4. The device of claim 3 ,
wherein the value of the MSD is 18.4 dB for band n79 based on the first combination of bands 1, n78 and n79,
wherein the value of the MSD is 4.6 dB for band n78 based on the first combination of bands 1, n78 and n79.

5. The device of claim 3 ,
wherein the value of the MSD is 16.3 dB for band n79 based on the second combination of bands 3, n78 and n79,
wherein the value of the MSD is 4.2 dB for band n78 based on the second combination of bands 3, n78 and n79.

6. The device of claim 3 ,
wherein the value of the MSD is 29.3 dB for band n79 based on the third combination of bands 19, n78 and n79,
wherein the value of the MSD is 28.8 dB for band n78 based on the third combination of bands 19, n78 and n79.

7. The device of claim 3 ,
wherein the value of the MSD is 30.1 dB for band n79 based on the fourth combination of bands 21, n78 and n79,
wherein the value of the MSD is 29.8 dB for band n78 based on the fourth combination of bands 21, n78 and n79.

8. The device of claim 3 ,
wherein for the first combination of bands 1, n78 and n79, the band 1 is used for the E-UTRA and the bands n78 and n79 are used for the NR,
wherein for the second combination of bands 3, n78 and n79, the band 3 is used for the E-UTRA and the bands n78 and n79 are used for the NR,
wherein for the third combination of bands 19, n78 and n79, the band 19 is used for the E-UTRA and the bands n78 and n79 are used for the NR,
wherein for the fourth combination of bands 21, n78 and n79, the band 21 is used for the E-UTRA and the bands n78 and n79 are used for the NR.

9. A method performed by a device configured with an Evolved Universal Terrestrial Radio Access (E-UTRA)-New Radio (NR) Dual Connectivity (EN-DC) in a wireless system, the method comprising:
receiving a downlink signal; and
transmitting an uplink signal via two bands which the EN-DC is configured to use,
wherein a value of Maximum Sensitivity Degradation (MSD) is applied to a reference sensitivity for receiving the downlink signal,
wherein the value of the MSD is pre-configured for a combination of bands 21 and n79,
wherein the value of the MSD is 18.4 dB for band 21 based on the combination of bands 21 and n79.

10. The method of claim 9 ,
wherein for the combination of bands 21 and n79, the band 21 is used for the E-UTRA and the band n79 is used for the NR.
