Abstract:
1. An apparatus comprising: a scheduler operative to schedule a plurality of terminals for data transmission and to assign the plurality of terminals with channels in at least two channel sets, wherein each channel set comprises a plurality of channels and is associated with a specific mapping of the plurality of channels to system resources available for data transmission, and wherein the mapping for each channel set is pseudo-random with respect to the mapping for each remaining one of the at least two channel sets for at least a subset of the plurality of channels, and the mapping of the subset of the plurality of channels uses a different overlapping scheme than a mapping of at least one other subset of the plurality of channels in the same channel set; and a controller operative to form channel assignments for the plurality of terminals, wherein each channel set is defined based on a channel tree and wherein each channel in the channel tree that is assigned to a terminal restricts at least one other channel in the same channel tree from being assigned.
