Title:
SELF-INTERFERENCE PROBLEM BY DUAL UPLINK TRANSMISSION FOR DC AND NR BAND COMBINATIONS
Document Type and Number:
WIPO Patent Application WO/2022/154451
Kind Code:
A1
Abstract:
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 4.5 dB for band n5, based on the three bands being bands 13, n5 and n77.
