Abstract:
According to certain embodiments, a method for use in a network node for scheduling wireless transmissions using a plurality of multi-user multiple-input multiple-output (MU-MIMO) transmission layers comprises determining a first wireless device is spatially pairable with a second wireless device and that a scheduling priority of the first device is higher than the second device. The method further comprises allocating frequency domain resources of a first transmission layer for the first device according to its scheduling priority and allocating frequency domain resources in a second transmission layer for the second device according to the priority of the first device. The amount of frequency domain resources allocated in the second transmission layer is no larger than that allocated in the first transmission layer. The method further comprises transmitting the data to first wireless device on first transmission layer and to second wireless device on the second transmission layer.
