ABSTRACT:
When establishing a link (i-j) between two nodes i, j in a mobile radio communications network, transmission parameters are assigned such that conflicts and interference with nodes that neighbor the nodes i and j are avoided. A time-slot and a frequency-code value are assigned to the link (i-j) from a defined set of time-slots T, and from a defined set of frequency-code values FC. Set T contains time slots (t) during which links in the network can be activated, and set FC contains frequency-code values (f, c) each of which specifies a frequency or a frequency-code pair for association with the links. A time slot t.sub.k is first chosen from set T which slot is not in use for links between node i and nodes neighboring node i, or for links between node j and nodes neighboring node j. A frequency-code value (f, c).sub.1 is next chosen from set FC which value is not in use by any node that neighbors node i or by any node that neighbors node j, during the chosen time slot t.sub.k. If no frequency-code value (f, c).sub.1 is available during the chosen time-slot t.sub.k, t.sub.k is removed from the set T of available time slots and another available time slot is chosen until a frequency-code value (f, c).sub.1 is available for the link (i-j) during the chosen time slot.
