A method may include receiving registration information from a first user equipment (UE) device and identifying a first multicast service associated with the first UE device. The method may also include transmitting, to the first UE device, a first file associated with the first multicast service and determining a number of UE devices associated with the first multicast service that have provided registration information. The method may further include determining whether a threshold associated with the number of UE devices that have provided registration information has been reached and initiating a broadcast of content associated with the first multicast service, in response to determining that the threshold has been reached.

A method for multi-channel beaconing in a network comprising for each network node of a plurality of network nodes: determining a link or a pseudo random sequence of links that identifies when and on what channel the network node is scheduled to transmit beacons; receiving the schedule for when and on which channel the network node should listen for beacons from one or more neighbor nodes of the plurality of network nodes; transmitting beacons based the established schedule; and listening for beacons from one or more neighbor nodes based on the schedule received from these neighbor nodes.

Systems, methods, or apparatus may comprise a computing device to transmit a first plurality of beacon frames, where each beacon frame includes a first network identifier, and a second plurality of beacon frames, where each beacon frame includes a different second network identifier. Further, the computing device may also cause the wireless transceiver to transmit the first plurality of beacon frames using a transmission parameter, and transmit the second plurality of beacon frames using a different transmission parameter—that differs from the transmission parameter of the first plurality of beacon frames.

A method and a device for searching for an access point in a wireless LAN are disclosed. An operating method of a station comprising a PCR and a WUR comprises the steps of: allowing the WUR operating in a wake up state to receive a WUR beacon frame from an access point; shifting an operating state of the PCR from a sleep state to the wake up state, when the WUR beacon frame is received; and allowing the PCR operating in the wake up state to communicate with the access point. Therefore, the performance of a communication system can be improved.
