Systems and methods for scheduling in a TDD system based on UE specific DL-UL gap requirements

A network node for scheduling downlink and/or uplink transmissions to a plurality of wireless communication devices in a Time-Division Duplexing, TDD, system, the network node comprising processing circuitry configured to cause the network node to:

• obtain path delay requirements of a plurality of wireless communication devices;
• determine downlink-to-uplink gap requirements of the plurality of wireless communication devices based on the path delay requirements of the plurality of wireless communication devices;
• and
• perform scheduling for the plurality of wireless communication devices based on the downlink-to-uplink gap requirements of the plurality of wireless communication devices, wherein performing scheduling for the plurality of wireless communication devices based on the downlink-to-uplink gap requirements of the plurality of wireless communication devices comprises:
• performing a baseline scheduling procedure that assigns transmission resources and scheduling priorities to a subset of the plurality of wireless communication devices;
• for each wireless communication device from among at least one of the subset of the plurality of wireless communication devices:
• computing a gap weight factor for the wireless communication device based on the downlink-to-uplink requirement of the wireless communication device;
• and
• computing a new scheduling priority for the wireless communication device based on a scheduling priority assigned to the wireless communication device by the baseline scheduling procedure and the gap weight factor computed for the wireless communication device;
• and
• reassigning transmission resources based on the new scheduling priority computed for the at least one of the subset of the plurality of wireless communication devices.
