Control device, network node and methods for allocating resources

A network node for a wireless communication system, the network node comprising:

• a processor configured to:
• receive an allocation of a common resource block (RB) for concurrent wireless transmission between the network node and a first client device using a first radio access technology (RAT), and/or between the network node and a second client device using a second RAT, wherein the first RAT is different from the second RAT,
• receive an allocation of a first precoder and/or a second precoder for the common RB, wherein the first precoder and the second precoder are configured for spatially multiplexing concurrent wireless transmission in the common RB;
• and
• a transceiver configured to:
• perform wireless transmission with the first client device in the common RB using the first RAT and the first precoder, and/or
• perform wireless transmission with the second client device in the common RB using the second RAT and the second precoder.

A method for a control device, the method comprising:

• obtaining a first channel estimation for a first client device;
• obtaining a second channel estimation for a second client device;
• allocating a common resource block (RB), for concurrent wireless transmission between a first network node and the first client device using a first radio access technology (RAT) and between a second network node and the second client device using a second RAT based on the first channel estimation and the second channel estimation, wherein the first RAT is different from the second RAT;
• allocating a first precoder for the common RB for the first client device and a second precoder for the common RB for the second client device based on at least one of the first channel estimation and second channel estimation,
• wherein the first precoder and the second precoder are configured for spatially multiplexing the concurrent wireless transmission between the first network node and the first client device and between the second network node and the second client device in the common RB.
