Abstract

The present invention discloses a method of transmitting/receiving signals by a terminal supporting EN-DC. The method comprises determining a number of interrupted slots; and transmitting or receiving the signals based on the number of interrupted slots, wherein the signals are not transmitted or received during the interrupted slots, wherein the number of interrupted slots is determined based on SCS of cell supporting the NR, a MG offset, and a MGL, and wherein the number of interrupted slots is 7 when the SCS is 15 kHz, the MG offset is 0.5 ms, and the MGL is 6 ms.

First claim

What is claimed is:

1 . A method of transmitting/receiving signals by a terminal supporting E-UTRA (Evolved Universal Terrestrial Radio Access)-NR (New Radio) Dual Connectivity (EN-DC), the method comprising:
determining a number of interrupted slots; and transmitting or receiving the signals based on the number of interrupted slots, wherein the signals are not transmitted or received during the interrupted slots, wherein the number of interrupted slots is determined based on subcarrier spacing (SCS) of cell supporting the NR, a measurement gap (MG) offset shift, and a MG length (MGL), and wherein the number of interrupted slots is 7 when the SCS is 15 kHz, the MG offset shift is 0.5 ms, and the MGL is 6 ms.

2 . The method of claim 1 , wherein the number of interrupted slots is 5 when the SCS is 15 kHz, the MG offset shift is 0.5 ms, and the MGL is 4 ms.

3 . The method of claim 1 , wherein the number of interrupted slots is 4 when the SCS is 15 kHz, the MG offset shift is 0.5 ms, and the MGL is 3 ms.

4 . The method of claim 1 , wherein the EN-DC is synchronous EN-DC.

5 . A terminal for transmitting/receiving signals, the terminal supporting E-UTRA (Evolved Universal Terrestrial Radio Access)-NR (New Radio) Dual Connectivity (EN-DC) and comprising:
a transceiver configured to transmit or receive the signals; and a processor configured to control the transceiver and determine a number of interrupted slots, wherein the processor controls the transceiver not to transmit or receive the signals during the interrupted slots, wherein the number of interrupted slots is determined based on subcarrier spacing (SCS) of cell supporting the NR, a measurement gap (MG) offset shift, and a MG length (MGL), wherein the number of interrupted slots is 7 when the SCS is 15 kHz, the MG offset shift is 0.5 ms, and the MGL is 6 ms.

6 . The method of claim 5 , wherein the number of interrupted slots is 5 when the SCS is 15 kHz, the MG offset shift is 0.5 ms, and the MGL is 4 ms.

7 . The method of claim 5 , wherein the number of interrupted slots is 4 when the SCS is 15 kHz, the MG offset shift is 0.5 ms, and the MGL is 3 ms.

8 . The method of claim 5 , wherein the EN-DC is synchronous EN-DC.
