Limited sensing for Vehicle-to-X communications

A user equipment, UE, that selects a radio resource for transmitting a packet, the UE comprising:

• a radio transceiver;
• at least one processor;
• and
• at least one memory coupled to the at least one processor and the radio transceiver, and storing program code that when executed by the at least one processor causes the at least one processor to perform operations comprising:
• obtain a basic period value related to expected timing of transmissions by a second UE;
• obtain a sub-period value that is less than the basic period value;
• monitor radio resources for a packet or booking message that is transmitted by the second UE and indicates that the second UE will potentially transmit a next packet using a radio resource and timing, wherein the monitoring is restricted to a timeframe determined based on the sub-period value within each occurrence of a time period determined based on the basic period value;
• and
• responsive to the monitoring identifying the packet or booking message, select a radio resource for use in transmitting a packet through the radio transceiver based on the radio resource and timing that is potentially to be used by the second UE to transmit the next packet.

A computer program product for selecting a radio resource to be used by a user equipment to transmit a packet, the computer program product comprising:

• a non-transitory computer readable medium storing program code that when executed by at least one processor of the user equipment causes the at least one processor to perform operations comprising:
• obtaining a basic period value related to expected timing of transmissions by a second UE;
• obtaining a sub-period value that is less than the basic period value;
• monitoring radio resources for a packet or booking message that is transmitted by the second UE and indicates that the second UE will potentially transmit a next packet using a radio resource and timing, wherein the monitoring is restricted to a timeframe determined based on the sub-period value within each occurrence of a time period determined based on the basic period value;
• and
• responsive to the monitoring identifying the packet or booking message, selecting (1006) a radio resource for use in transmitting a packet based on the radio resource and timing that is potentially to be used by the second UE to transmit the next packet.
