Resource configuration for sidelink communication
The disclosed techniques enable resource configuration for sidelink communications. An example method includes receiving, by a first network element, a sidelink resource request transmitted from a communication node. The method also includes communicating, via an interface between the first network element and a second network element, information about resource configuration for the communication node. The method further includes transmitting, by the first network element, a response to the sidelink resource request.
