1. An apparatus comprising a memory and a processor, the processor configured to cause a Neighbor Awareness Networking (NAN) device to:

  • process reception of a scheduling message comprising a scheduling attribute from a coordinator of a multicast group, the scheduling attribute comprising a service identifier (ID) corresponding to a service, scheduling information to indicate one or more timeblocks, a list of NAN devices belonging to the multicast group, and a scheduling rank of the coordinator;

    based on the scheduling attribute, connect with a first NAN device of the multicast group during at least one of the timeblocks to communicate traffic of the service; and

    transmit to the coordinator a cant connect message comprising a cant-connect attribute indicating a second NAN device of the multicast group based on a failure to connect to the second NAN device;

    wherein the first NAN device determines the failure to connect based on failing to receive a refresh message from the second NAN device of the multicast group for a predefined duration, and wherein the predefined duration is defined as a multiple of a refresh interval specified in the scheduling message.
