Abstract
An operation method of a first communication node in a communication system supporting Vehicle-to-Everything (V2X) communications can include: determining at least one frequency band for transmission of semi-persistent scheduling (SPS) traffic; generating user equipment (UE) assistance information including information indicating the at least one frequency band; and transmitting the UE assistance information to a base station supporting the V2X communication.

-20. (canceled)
An operation method of a first communication node in a communication system supporting Vehicle-to-Everything (V2X) communication, the operation method comprising:
- measuring congestion in a first carrier used for the V2X communication with a second communication node;
- determining one or more candidate carriers usable for the V2X communication with the second communication node when the congestion in the first carrier is greater than or equal to a preconfigured threshold;
- generating a new semi-persistent scheduling (SPS) configuration applied to the first carrier and the one or more candidate carriers by reconfiguring an original SPS configuration applied to the first carrier;
- and
- performing the V2X communication with the second communication node using the first carrier and the one or more candidate carriers to which the new SPS configuration is applied.

- determining one or more candidate carriers usable for the V2X communication with the second communication node when the congestion in the first carrier is greater than or equal to a preconfigured threshold;
- transmitting user equipment (UE) assistance information including information of the one or more candidate carriers to a base station supporting the V2X communication;
- receiving a message including new semi-persistent scheduling (SPS) configuration applied to the first carrier and the one or more candidate carriers from the base station;
- and
- performing the V2X communication with the second communication node using the first carrier and the one or more candidate carriers to which the new SPS configuration is applied,
- wherein the new SPS configuration is SPS configuration which is reconfigured based on original SPS configuration applied to the first carrier.
An operation method of a first communication node in a communication system supporting Vehicle-to-Everything (V2X) communication, the operation method comprising:
- measuring congestion in a first carrier used for the V2X communication with a second communication node and carriers aggregated with the first carrier;
- transmitting a message including the congestion to a base station supporting the V2X communication;
- receiving a message including new semi-persistent scheduling (SPS) configuration applied to the first carrier and one or more candidate carriers determined based on the congestion from the base station;
- and
- performing the V2X communication with the second communication node using the first carrier and the one or more candidate carriers to which the new SPS configuration is applied,
- wherein the new SPS configuration is SPS configuration which is reconfigured based on original SPS configuration applied to the first carrier.
