Claim of US Patent No. 10,772,107

1. A method for transmitting a vehicle-to-X (V2X) message in a wireless communication system, the method performed by a user equipment (UE), and comprising:allocating a high priority resource pool configured to be used to transmit a V2X message having a high priority,
wherein the high priority resource pool includes a plurality of resource regions, and
wherein, in the high priority resource pool, only a transmission of the V2X message having the high priority is performed;
configuring the plurality of resource regions in the high priority resource pool such that the V2X message having the high priority is transmitted on a first resource region that is different from a second resource region that is used by another UE to transmit a high-priority V2X message; and
transmitting the V2X message having the high priority via the first resource region,
wherein the high priority resource pool is configured to have a first period, and a low priority resource pool is configured to have a second period,
wherein the first period is longer than the second period,
wherein the high priority resource pool is repeated based on the first period and the low priority resource pool is repeated based on the second period,
wherein the low priority resource pool is a resource pool used for transmitting a V2X message having a low priority,
wherein the high priority resource pool is a resource pool which comprises a larger amount of resources rather than the low priority resource pool on a frequency domain and a time domain,
wherein the V2X message having the high priority is a security message having a longer period rather than another V2X message having a low priority,
wherein the UE transmits the V2X message having the high priority to a pedestrian UE,
wherein the pedestrian UE is a UE possessed by a pedestrian,
wherein the high priority resource pool is a common resource pool between the UE and the pedestrian UE, and
wherein the high priority resource pool is an only resource pool capable of receiving the V2X message having the high priority by the pedestrian UE.
