Abstract
One disclosure of the present specification provides a method by which a UE performs sidelink communication. The method may comprise the steps of: performing sidelink communication on the basis of a first RAT; switching a RAT for the sidelink communication from the first RAT to a second RAT; performing the sidelink communication on the basis of the second RAT; and communicating with a base station on the basis of NR.
Claims12
A method for a user equipment (UE) to perform sidelink communication, the method comprising:
- switching from an Evolved Universal Terrestrial Radio Access (E-UTRA) Vehicle-to-everything (V2X) sidelink to a New Radio (NR) V2X sidelink,
- wherein interruption of communication with the base station due to the switching from the E-UTRA V2X sidelink to the NR V2X sidelink is applied to a pre-configured number of NR slots according to Subcarrier Spacing (SCS) for the communication with the base station, due to the switching from the E-UTRA V2X sidelink to the NR V2X sidelink;
- and
- switching from the NR V2X sidelink to the E-UTRA V2X sidelink,
- wherein interruption of communication with the base station due to the switching from the NR V2X sidelink to the E-UTRA V2X sidelink is applied to a pre-configured number of NR slots according to the SCS for the communication with the base station, due to the switching from the E-UTRA V2X sidelink to the NR V2X sidelink,
- wherein the pre-configured number of the NR slots is 2 NR slots, based on the SCS for the communication with the base station being 15 kHz,
- wherein the pre-configured number of the NR slots is 2 NR slots, based on the SCS for the communication with the base station being 30 kHz, and
- wherein the pre-configured number of the NR slots is 2 NR slots, based on the SCS for the communication with the base station being 60 kHz.
5 more elements
A user equipment (UE) that performs sidelink communication, the UE comprising:
- at least one processor;
- and
- at least one memory for storing instructions and operably electrically connectable with the at least one processor,
- wherein the operation performed based on the instructions being executed by the at least one processor comprises:
- switching from an Evolved Universal Terrestrial Radio Access (E-UTRA) Vehicle-to-everything (V2X) sidelink to a New Radio (NR) V2X sidelink,
- wherein interruption of communication with the base station due to the switching from the E-UTRA V2X sidelink to the NR V2X sidelink is applied to a pre-configured number of NR slots according to Subcarrier Spacing (SCS) for the communication with the base station, due to the switching from the E-UTRA V2X sidelink to the NR V2X sidelink;
- and
- switching from the NR V2X sidelink to the E-UTRA V2X sidelink,
- wherein interruption of communication with the base station due to the switching from the NR V2X sidelink to the E-UTRA V2X sidelink is applied to a pre-configured number of NR slots according to the SCS for the communication with the base station, due to the switching from the E-UTRA V2X sidelink to the NR V2X sidelink,
- wherein the pre-configured number of the NR slots is 2 NR slots, based on the SCS for the communication with the base station being 15 kHz,
- wherein the pre-configured number of the NR slots is 2 NR slots, based on the SCS for the communication with the base station being 30 kHz, and
- wherein the pre-configured number of the NR slots is 2 NR slots, based on the SCS for the communication with the base station being 60 kHz.
