Communication apparatus, base station and method

A base station comprising:

• a memory storing a program;
• and
• one or more processors configured to execute the program to:
• receive, from a communication apparatus, a first radio resource control, RRC, message including path information, the path information including information for indicating each of a plurality of waypoints and information for indicating each of a plurality of timestamps, the each of the plurality of timestamps indicating a time to arrive at the each of the plurality of waypoints;
• obtain the path information included in the first RRC message;
• and
• receive, from the communication apparatus, a second RRC message including information for indicating an availability of the path information in a case where the communication apparatus has at least one waypoint which is not included in the path information previously transmitted to the base station.

A method performed by a communication apparatus, comprising:

• obtaining path information including information for indicating each of a plurality of waypoints and information for indicating each of a plurality of timestamps, the each of the plurality of timestamps indicating a time to arrive at the each of the plurality of waypoints;
• transmitting, to a base station, a first radio resource control, RRC, message including the path information;
• and
• transmitting, to the base station, a second RRC message including information for indicating an availability of the path information in a case where the communication apparatus has at least one waypoint which is not included in the path information previously transmitted to the base station.
