Abstract

Claims (39)

1 . A method for beamwidth management in a wireless communication system, the method comprising:

determining a first set of user equipments (UEs) served by a beam of a network node in a transmission time interval (TTI);

comparing a first number of UEs in the first set of UEs with a threshold number of UEs that can be served by the beam of the network node in the TTI, wherein the threshold number of UEs is determined at the network node and corresponds to a number of schedulable UEs per TTI;

adjusting a beamwidth of the beam, based on a result of the comparing, to create a second set of UEs served by the beam with the adjusted beamwidth in a subsequent TTI; and

forming the beam with the adjusted beamwidth,

wherein the adjusting of the beamwidth of the beam based on the result of the comparing comprises increasing the beamwidth of the beam by combining the beam with at least one neighboring beam based on determining that the first number of UEs in the first set of UEs is less than the threshold number of UEs.

2 . The method of claim 1 , wherein the second set of UEs is created based on the adjusted beamwidth, and

wherein a second number of UEs in the second set of UEs is different from the first number of UEs in the first set of UEs.

3 . The method of claim 1 , wherein the adjusting of the beamwidth of the beam based on the result of the comparing further comprises decreasing the beamwidth based on determining that the first number of UEs in the first set of UEs is greater than the threshold number of UEs.

4 . The method of claim 3 , wherein the decreasing of the beamwidth comprises splitting the beam into at least two split beams.

5 . The method of claim 4 , further comprising:

splitting the first set of UEs served by the beam into as many sets as a number of split beams based on determining that the first number of UEs in the first set of UEs is greater than the threshold number of UEs.

6 . The method of claim 1 , further comprising:

including at least one UE that is serviceable by the combined beam, in the first set of UEs to form the second set of UEs, based on determining that the first number of UEs in the first set of UEs is less than the threshold number of UEs.

7 . The method of claim 6 , further comprising:

receiving a scheduler output that comprises a prioritized scheduling list of UEs that are schedulable in the combined beam; and

selecting the at least one UE from among the UEs that are schedulable in the combined beam, based on a scheduling priority of the at least one UE.

8 . The method of the claim 1 , further comprising:

providing a plurality of parameters as an input to an Artificial Intelligence (AI) module;

obtaining a beamwidth adjustment value based on the plurality of parameters; and

adjusting the beamwidth of the beam, based on the obtained beamwidth adjustment value, such that the second set of UEs can be served by the beam with the adjusted beamwidth in a subsequent TTI interval,

wherein the plurality of parameters comprises at least one of a scheduling pattern, a number of serviceable UEs, and a throughput of each UE in the first set of UEs.

9 . An apparatus for beamwidth management in a wireless communication system, the apparatus comprising:

at least one processor configured to:

determine a first set of user equipments (UEs) served by a beam of the apparatus in a transmission time interval (TTI), wherein the apparatus is a network node;

compare a first number of UEs in the first set of UEs with a threshold number of UEs that can be served by the beam of the apparatus in the TTI, wherein the threshold number of UEs is determined at the network node and corresponds to a number of schedulable UEs per TTI;

adjust a beamwidth of the beam, based on a result of the comparison, to create a second set of UEs served by the beam with the adjusted beamwidth in a subsequent TTI; and

form the beam with the adjusted beamwidth,

wherein the at least one processor is further configured to increase the beamwidth of the beam by combining the beam with at least one neighboring beam based on determining that the first number of UEs in the first set of UEs is less than the threshold number of UEs.

10 . The apparatus of claim 9 , wherein the second set of UEs is created based on the adjusted beamwidth, and

wherein a second number of UEs in the second set of UEs is different from the first number of UEs in the first set of UEs.

11 . The apparatus of claim 9 , wherein the at least one processor is further configured to decrease the beamwidth based on determining that the first number of UEs in the first set of UEs is greater than the threshold number of UEs.

12 . The apparatus of claim 11 , wherein the at least one processor is further configured to:

split the beam into at least two split beams based on determining that the first number of UEs in the first set of UEs is greater than the threshold number of UEs; and

split the first set of the UEs served by the beam into as many sets as a number of split beams based on determining that the first number of UEs in the first set of UEs is greater than the threshold number of UEs.

13 . The apparatus of claim 9 , wherein the at least one processor is further configured to include at least one UE that is serviceable by the combined beam in the first set of UEs, to form the second set of UEs, based on determining that the first number of UEs in the first set of UEs is less than the threshold number of UEs.

14 . The apparatus of claim 13 , wherein the at least one processor is further configured to:

receive a scheduler output that comprises a prioritized scheduling list of UEs that are schedulable in the combined beam; and

select the at least one UE from among the UEs that are schedulable in the combined beam, based on a scheduling priority of the at least one UE.
