SELF-INTERFERENCE PROBLEM BY DUAL UPLINK TRANSMISSION FOR DC AND NR CA BAND COMBINATIONS

A disclosure of this specification provides 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 11, n28 and n77, a second combination of band 2, n5 and n77, a third combination of bands 13, n2 and n77, a fourth combination of bands 66, n5 and n77, a fifth combination of bands 18, n28 and n77, a sixth combination of bands 18, n3 and n41, a seventh combination of bands 18, n41 and n77, an eighth combination of bands 2, n71 and n78, a ninth combination of bands 7, n71 and n78, a tenth combination of bands 71, n38 and n78, an eleventh combination of bands 5, n66 and n78, a twelfth combination of bands 71, n66 and n78, a thirteenth combination of bands 5, n38 and n66, a fourteenth combination of bands 12, n2 and n38, a fifteenth combination of bands 12, n2 and n41, a sixteenth combination of bands 2, n66 and n77 or a seventeenth combination of bands 11, n3 and n77.
