Abstract

A method can be used for channel access in an industrial wireless network. A network controller allocates time/frequency resource units in a set of guaranteed timeslots to packet transceivers in the industrial wireless network. The guaranteed timeslots are timewise divided into slots and frequency wise divided into channels, where one slot-channel pair defines one time/frequency resource unit. The network controller provides to the packet transceivers information about the time/frequency resource units allocated to the packet transceivers. The packet transceivers map packets of their own traffic flows to their allocated time/frequency resource units in each set of guaranteed timeslots. The packets for each packet transceiver are mapped according to priority-based scheduling of its own traffic flows and independently of any mapping of packets of other packet transceivers in the industrial wireless network.
