Methods for specifying the type of MAC address with dynamic assignment mechanisms

A method performed by a WTRU may comprise receiving context information from infrastructure equipment and selecting a SLAP quadrant for MAC address allocation. The selecting may be based on the context information received from the infrastructure equipment, which may be a bootstrapping server for the WTRU. The method may further comprise transmitting, to a DHCP server, a DHCP message indicating the selected SLAP quadrant. In response to the transmitted DHCP message, a MAC address may be received and configured to the WTRU. Context information includes, but is not limited to, a number of nodes in a network, a type of network deployment, a type of network, a mobility configuration, a type of device management, a battery lifetime, a location or privacy configuration.
