Semi-persistent resource allocation for v2v traffic

An integrated circuit configured to control operation of a vehicular mobile terminal to transmit periodic data to one or more receiving entities, the integrated circuit comprising:

• transmission circuitry configured to control:
• transmitting, to a radio base station, information on the periodic data including information related to vehicle parameters supported by the vehicular mobile terminal, the information on the vehicle parameters usable by the radio base station to determine different possible transmission periodicities of one or more data components of the periodic data, and
• in response to one of the vehicle parameters in a previous value range changing to be in a different value range, transmitting, to the radio base station, information related to the changed vehicle parameter, and
• indicating, to the radio base station, that the one or more data components of the periodic data are available to be transmitted from the vehicular mobile terminal to the one or more receiving entities, and
• reception circuitry configured to control:
• receiving, from the radio base station, a plurality of semi-persistent radio resource configurations configured by the radio base station based on the information on the periodic data, each of the plurality of semi-persistent radio resource configurations usable to transmit at least one of the one or more data components of the periodic data, and
• receiving, from the radio base station, an activation command to activate one or more of the plurality of semi-persistent radio resource configurations, selected by the radio base station based on the information related to the changed vehicle parameter, to periodically allocate radio resources used to transmit the one or more data components of the periodic data,
• wherein
• the transmission circuitry, in operation, controls transmitting, to the one or more receiving entities, the one or more data components of the periodic data using the allocated radio resources and using the transmission periodicity defined by the activated one or more semi-persistent radio resource configurations.
