Abstract: A method for time-slotted scheduling of packets in timeslots between N nodes and K>1 access points in an industrial wireless network, performed by a network controller of the industrial wireless network. The method includes determining the time-slotted scheduling by allocating each timeslot to a respective one of the nodes, wherein each timeslot for each node is divided in K sub-slots, one for each access point, such that in sub-slot k of each timeslot, where 1≤k≤K, transmission or reception of a packet is made between access point k and the node to which that timeslot is allocated. The method includes providing information to the access points about the determined time-slotted scheduling.
