Abstract: A primary transmitter of a multicast communication system transmits in-band backhaul to a relay transmitter using an LDM signal that also carries services to end-users. The relay transmitter processes received wireless signal to extract the in-band backhaul and re-transmits services obtained from the in-band backhaul in same or different frequency channel. The in-band backhaul may be transmitted in a high-capacity layer of the LDM signal carrying or in a separate timeslot. Transmitter-specific signature signals may be used for loopback and forward channel estimation at the relay transmitter. The in-band backhaul may also carry service data for devices in a different network.

Abstract: Technologies are generally described for clusterhead selection in a communication network. In an example, a first node may be configured to send a first responsibility and availability. In some examples, the first responsibility indicates a responsibility attributed to the second node to be the clusterhead for the first node. In some examples, the first availability indicates an availability of the first node to be the clusterhead for the second node. In some examples, the first node is effective to receive a second responsibility and availability; the second responsibility indicating a responsibility attributed to the first node to be the clusterhead for a second node; the second availability indicating an availability of the second node to be the clusterhead for the first node. In some examples, the first node is effective to determine the clusterhead based on the first and second responsibility and the first and second availability.
