Then, the centroids are recalculated on the base of the last assignment stage.
Also update the selected pairing link e that has been added in M i (t) in the channel assignment stage with the new MIMO mode determined in step 4.
We show that they will clearly benefit from the introduced facilitation of the resonance assignment stage, even in cases where it is not unique.
The o(t) vectors resulting from the soft assignment stage (Eq. 19) are used as frame observation sequences.
In the channel assignment stage, all effective DoFs on the transmitter and receiver are assumed to be used for the intended MIMO transmissions.
A candidate link e must satisfy the following two conditions: (a) e is the only link within the interference range of link e ′ that has been assigned on channel i in the channel assignment stage; (b) link e has not paired with any link.
Note that if this happens, e can no longer transmit as many streams as its full DoFs which was assumed in the channel assignment stage.
The channel assignment stage results in a schedule in which interfering links can be active in a time slot only if each of them can be exclusively assigned a distinct channel.
Some links are not assigned a channel and scheduled to be active during time slot t in the channel assignment stage because no more channels are available, that is, other links in the interference range have higher weights and have used up all available channels.
With MIMO, an unassigned link may share a channel with a neighboring link that has been assigned to transmit on that channel in the previous channel assignment stage.
