US 2023/0156589 A1 · CELL SELECTION, NETWORK SELECTION, TRACKING AREA MANAGEMENT, AND PAGING FOR AERIAL OPERATION

Abstract

Methods, systems, and devices for wireless communication are described. In one example, an aerial user equipment (UE) may receive an indication of a priority for cell selection for aerial UEs from each cell in a set of cells and may select a cell from the set of cells based on the priority of each cell in the set of cells. In another example, an aerial UE may connect to a network available to aerial UEs and non-aerial UEs for auxiliary communications, when appropriate. In yet another example, when an aerial UE transitions to a new mission status, the aerial UE may transmit a tracking area update (TAU) if the aerial UE is connected to a cell in a tracking area that does not support the new mission status. In yet another example, a base station may page an aerial UE based on a mission status of the aerial UE.

Claims24

Dependent claims

A method for wireless communication at an aerial user equipment (UE), comprising:

receiving first system information indicating a first priority of a first cell for cell selection for aerial UEs;
receiving second system information indicating a second priority of a second cell for cell selection for aerial UEs;
identifying a mission status of the aerial UE;
and
selecting the first cell or the second cell for communications based at least in part on the first priority of the first cell, the second priority of the second cell, and the mission status of the aerial UE.

2 more elements

An apparatus for wireless communication at an aerial user equipment (UE), comprising:

a processor;
and
a memory coupled with the processor, with instructions stored in the memory, the instructions being executable by the processor to cause the apparatus to:
receive first system information indicating a first priority of a first cell for cell selection for aerial UEs;
receive second system information indicating a second priority of a second cell for cell selection for aerial UEs;
identify a mission status of the aerial UE;
and
select the first cell or the second cell for communications based at least in part on the first priority of the first cell, the second priority of the second cell, and the mission status of the aerial UE.

5 more elements

A non-transitory computer-readable medium storing code for wireless communication at an aerial user equipment (UE), the code comprising instructions executable by a processor to:

receive first system information indicating a first priority of a first cell for cell selection for aerial UEs;
receive second system information indicating a second priority of a second cell for cell selection for aerial UEs;
identify a mission status of the aerial UE;
and
select the first cell or the second cell for communications based at least in part on the first priority of the first cell, the second priority of the second cell, and the mission status of the aerial UE.
