Abstract

Systems and methods are provided for providing explicit MU-MIMO pairing indicator. Methods include maintaining a profile of one or more wireless devices in a wireless network using MU-MIMO. Methods further include receiving an indicator from one or more access nodes identifying MU-MIMO pairing for one or more wireless devices. Methods further include adjusting one or more of beamforming, layer assignment or throughput of the wireless network.

Claims (38)

1 . A method comprising:

maintaining a profile of one or more wireless devices in a wireless network using multiuser multiple input multiple output (MU-MIMO);

receiving at the profile of the one or more wireless devices an indicator from one or more access nodes identifying MU-MIMO pairing for the one or more wireless devices in the wireless network, wherein the indicator is available to a user of the one or more wireless devices; and

adjusting one or more of beamforming, layer assignment or throughput of the wireless network based on the one or more wireless devices using MU-MIMO connections.

2 . The method of claim 1 , wherein the wireless network is a 5G wireless network and the one or more access nodes are gNB devices.

3 . The method of claim 1 , wherein the indicator is a downlink control information (DCI) message which includes performing downlink and uplink scheduling.

4 . The method of claim 1 , further comprising:

accessing one or more locations of the one or more wireless devices using MU-MIMO.

5 . The method of claim 4 , further comprising:

accessing usage information for the one or more wireless devices using MU-MIMO.

6 . The method of claim 5 , further comprising:

identifying from the one or more wireless devices using MU-MIMO, the wireless devices experiencing the most MU-MIMO pairing.

7 . The method of claim 1 , wherein adjusting one or more of beamforming, layer assignment or throughput of the wireless network based on the one or more wireless devices using MU-MIMO connections serves to improve the throughput and/or improve spectral efficiency of the one or more access nodes.

8 . A system comprising:

an access node including at least one electronic processor configured to perform operations including:

maintaining a profile of one or more wireless devices in a wireless network using multiuser multiple input multiple output (MU-MIMO);

receiving at the profile of the one or more wireless devices an indicator from one or more access nodes identifying MU-MIMO pairing for the one or more wireless devices in the wireless network, wherein the indicator is available to a user of the one or more wireless devices; and

adjusting one or more of beamforming, layer assignment or throughput of the wireless network based on the one or more wireless device paired for MU-MIMO connections.

9 . The system of claim 8 , wherein the wireless network is a 5G wireless network and the access node is a gNB device.

10 . The system of claim 8 , wherein the indicator is a downlink control information (DCI) message which includes performing downlink and uplink scheduling.

11 . The system of claim 8 , further comprising:

accessing one or more locations of the one or more wireless devices paired for MU-MIMO.

12 . The system of claim 11 , further comprising:

accessing usage information for the one or more wireless devices paired for MU-MIMO.

13 . The system of claim 11 , wherein adjusting one or more of beamforming, layer assignment or throughput of the wireless network based on the one or more wireless devices paired for MU-MIMO serves to improve the throughput and/or improve spectral efficiency of the one or more access nodes.

14 . A non-transitory computer-readable medium storing instructions, when executed by at least one processor, configuring the at least one processor to:

maintain a profile of one or more wireless devices in a wireless network using multiuser multiple input multiple output (MU-MIMO);

determine that the one or more wireless devices is paired with an access node for MU-MIMO based on satisfying a threshold; and

store an indicator at a profile of the one or more wireless devices that indicates the one or more wireless devices are paired for MU-MIMO, wherein the indicator is available to a user of the one or more wireless devices;

adjust one or more of beamforming, layer assignment or throughput of the wireless network based on the one or more wireless devices using MU-MIMO connections.

15 . The non-transitory computer-readable medium storing instructions of claim 14 , wherein the wireless network is a 5G wireless network and the access node is a gNB device.

16 . The non-transitory computer-readable medium storing instructions of claim 14 , wherein the indicator is based on a downlink control information (DCI) message which includes downlink and uplink scheduling.

17 . The non-transitory computer-readable medium storing instructions of claim 14 , non-transitory computer-readable medium storing instructions:

accessing one or more locations of the one or more wireless devices using MU-MIMO.

18 . The non-transitory computer-readable medium storing instructions of claim 17 , non-transitory computer-readable medium storing instructions:

access usage information for the one or more wireless devices using MU-MIMO.

19 . The non-transitory computer-readable medium storing instructions of claim 14 , wherein the at least one processor is further configured to:

adjust one or more of beamforming, layer assignment or throughput of the wireless network based on the one or more wireless devices using MU-MIMO connections.
