Abstract

Method performed by a first network node (111) for handling scheduling of wireless devices. The first network node (111) obtains information about a first type of time resource used by HD-FDD wireless devices (151). The first network node (111) also obtains information about a second type of time resource not used by the HD-FDD wireless devices (151) due to a transition at the HD-FDD wireless devices (151) between UL and DL. The first network node (111) schedules a first wireless device out of FD-FDD wireless devices (152) during the second type of time resource, based on the obtained information about the second type. The first network node (111) decides whether or not to schedule a second wireless device out of the FD-FDD wireless devices (152) during the first type of time resource, based on the obtained information about the first type, and further based on whether first conditions are met.

obtain information about a second type of time resource, wherein the second type of time resource is not to be used by the one or more HD-FDD wireless devices due to a transition at the one or more HD-FDD wireless devices between Uplink (UL) and Downlink (DL) time resources;

schedule a first wireless device out of one or more Full Duplex-Frequency Division Duplex (FD-FDD) wireless devices during the second type of time resource, based on the obtained information about the second type of time resource; and

decide whether or not to schedule a second wireless device out of the one or more FD-FDD wireless devices during the first type of time resource, based on the obtained information about the first type of time resource, and further based on whether one or more first conditions are met.

2. The non-transitory computer-readable medium of claim 1, wherein the one or more first conditions comprise one or more of:

a number of HD-FDD wireless devices in a first cell served by the first network node is below a first threshold;

a number of HD-FDD wireless devices scheduled or to be scheduled during the first type of time resource is below a second threshold; and

a signal quality during the first type of time resource is above a third threshold.

3. The non-transitory computer-readable medium of claim 1, wherein the execution of the program code further causes the controller to:

obtain information about a third type of time resource, the third type of time resource being a time resource other than the first and the second types of time resources.

4. The non-transitory computer-readable medium of claim 3, wherein the obtained information about the first type, the second type, and the third type of time resource comprises a pattern of at least one of:

the first type of time resource,

the second type of time resource, and

the third type of time resource.

5. The non-transitory computer-readable medium of claim 3, wherein the execution of the program code further causes the controller to:

schedule a third wireless device out of the one or more FD-FDD wireless devices during the third type of time resource, when one or more second conditions are met.

6. The non-transitory computer-readable medium of claim 5, wherein the one or more second conditions comprise one or more of:

a number of FD-FDD wireless devices in a first cell served by the first network node is below a fourth threshold;

a number of FD-FDD wireless devices scheduled or expected to be scheduled during the third type of time resource is below a fifth threshold; and

a signaling quality during the third type of time resource is above a sixth threshold.

7. The non-transitory computer-readable medium of claim 3, wherein in obtaining the information about at least one of the first, second, and third types of time resource, the execution of the program code further causes the controller to:

autonomously determine the information about the at least one of the first, second, and third types of time resource,

receive the information about the at least one of the first, second, and third types of time resource, from a second network node configured to operate in the wireless communications network;

receive the information about the at least one of the first, second, and third types of time resource, from another wireless device;

or

read pre-defined or stored information.

8. The non-transitory computer-readable medium of claim 3, wherein the execution of the program code further causes the controller to:
