Abstract: A method of operating a network node of a network, a network node, a network system, a computer-readable medium, and a program element A method (300) of operating a network node (101-104) of a network system (100), comprising the steps of generating (305) a signal to be transmitted, selecting (310) one of a plurality of communication channels (105-108) of the network system (100) for transmitting the signal, and, in case that the selected channel (105-108) is not ready for transmitting the signal, selecting (345) another one of the plurality of communication channels (105-108) for transmitting the signal.

Abstract: The network has several terminals and an associated central station for allocating time slices of a subsequent time multiplex frame for wireless transmission of packets after receiving a request for transmission of packets during a previous time multiplex frame. After receiving all requests the central station determines a first subset of all transmit terminals intending to send packets to several receive terminals and a second subset of the remaining transmit terminals, sequences the transmit terminals according to the number of receive terminals they intend to transmit to, divides receive terminals associated with a transmit terminal into a first group containing all receive terminals already used as transmit terminals and a second group with all other receive terminals, sequences the receive terminals in both groups according to the transmit sequence as transmit terminals and first selects the receive terminals in the second group. Independent claims are also included for the following: a central station in a wireless network.
