Method for merging and transmitting, by network, vru messages in wireless communication system supporting sidelink, and apparatus therefor

A network for merging and transmitting a vulnerable road user (VRU) message in a wireless communication system for supporting sidelink, comprising:

• a radio frequency (RF) transceiver;
• and
• a processor connected to the RF transceiver,
• wherein the processor controls the RF transceiver to receive a first VRU message including information on a first VRU through uplink, to transmit a second VRU message obtained by merging a plurality of VRU messages received from a plurality of VRUs for a preconfigured time period through downlink at a preconfigured time point, and
• wherein the processor determines whether to merge the first VRU message to the second VRU message based on a mobility change calculated based on previous mobility information for the first VRU and mobility information acquired from the first VRU message, and independently transmits the first VRU message through downlink without merging with the second VRU message when the mobility change is equal to or greater than a preconfigured threshold.

A chip set for merging and transmitting a vulnerable road user (VRU) message in a wireless communication system for supporting sidelink, comprising:

• at least one processor;
• and
• at least one memory operatively connected to the at least one processor and configured to cause the at least one processor to perform an operation when being executed,
• wherein the operation includes receiving a first VRU message including information on a first VRU through uplink, transmitting a second VRU message obtained by merging a plurality of VRU messages received from a plurality of VRUs for a preconfigured time period through downlink at a preconfigured time point, determining whether to merge the first VRU message to the second VRU message based on a mobility change calculated based on previous mobility information for the first VRU and mobility information acquired from the first VRU message, and independently transmitting the first VRU message through downlink without merging with the second VRU message when the mobility change is equal to or greater than a preconfigured threshold.
