Vehicular communication of road traffic status

An apparatus comprising

• at least one processor;
• and
• at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to
• measure signalling transmitted from vehicle devices, to obtain the status of road traffic in the proximity of a road side unit;
• in response to a pre-defined triggering event being detected in the obtained status of the road traffic in the proximity of the road side unit, the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
• select at least one road side unit operation mode for communication, based on the obtained status of the road traffic, wherein the at least one selected road side unit operation mode for the communication comprises one or a combination of the following modes:
• a user-equipment-type operational mode, a base station-type operational mode, or a small-cell base station operational mode;
• and
• set an operation mode of the road side unit to correspond to the at least one selected road side unit operation mode for the communication.

A computer program product embodied on a non-transitory distribution medium readable by a computer and comprising program instructions which, when loaded into the computer, execute a computer process that cause the computer to perform at least the following:

• measuring, in a road side unit, signalling transmitted from vehicle devices, to obtain a status of road traffic in proximity of the road side unit;
• in response to a pre-defined triggering event being detected in the obtained status of the road traffic in the proximity of the road side unit, performing operations comprising:
• selecting at least one road side unit operation mode for communication, based on the obtained status of the road traffic, wherein the at least one selected road side unit operation mode for the communication comprises one or a combination of the following modes:
• a user-equipment-type operational mode, a base station-type operational mode, or a small-cell base station operational mode;
• and
• setting, in the road side unit, an operation mode of the road side unit to correspond to the at least one selected road side unit operation mode for the communication.
