Abrégé
(EN)

Member nodes of a wireless point-to-multipoint (PMP) network may participate in mobile ad hoc (MANET) or mesh communications with other nodes on the same channels used by the network for PMP communications. A PMP network base station node transmits a downlink signal defining a downlink map for scheduling first time periods for transmitting messages to subscriber station nodes, and an uplink map for scheduling second time periods allowing a subscriber station node to transmit messages to the base station node in a scheduled second time period. A MANET/mesh zone is allocated in either or both the downlink and the uplink maps, each zone operating to reserve one or more time slots and channels in which the base station and other nodes may communicate using a MANET/mesh protocol, thus avoiding interference with communications that are being conducted between the base and the subscriber station nodes under the PMP protocol.
