As we know in V2X communication over PC5 has derived into two modes ie Mode3 and Mode4.
In Mode4: which is know sensing based persistent scheduling, UE/Vechicle will scan the un-licensed spectrum and get the free resources to sending messages. While sending it will send control information saying about data and which resource blocks I am using. so, while any UE sensing for the free resource it will listen the SCI information which was broadcasting on the un-licensed spectrum.

In Mode3: N/W will provide the resource to UE / Vechicle with corresponding control information.

On an abstract V2X communication is a broadcast information, interested UE/Vechicle will listen and act accordingly.

At radio level it is a broadcast information, but at application i.e V2X application defined by 3GPP might have mechanism for End-to-End communication.

Please anyone correct me if I am wrong.

Before sidelink communication (data transmission on PSSCH) happens between UE's, is it sidelink discovery needs to happen?
Does the V2x sidelink communication needs discovery?

UE gets DCI format 5/5A for sidelink grant from Enb in PDCCH.
Then UE constructs SCI0/SCI1 and transmits on PSCCH to indicate PSSCH resources and MCS etc.,
How receiving UE knows where to listen for PSCCH in sidelink communication ?
