Abstract
A method includes detecting that a first satellite of a non-terrestrial network is moving out of a field of view of a user endpoint device that is currently connected to the non-terrestrial network, estimating a time at which a second satellite of the non-terrestrial network is expected to enter the field of view of the user endpoint device, selecting, in response to the time at which the second satellite of the non-terrestrial network is expected to enter the field of view of the user endpoint device, an uplink power for the user endpoint device, and sending, to the user endpoint device, an instruction to transmit at the uplink power that is selected.

A method comprising:
- detecting, by a processing system including at least one processor, that a first satellite of a non-terrestrial network is moving out of a field of view of a user endpoint device that is currently connected to the non-terrestrial network, wherein the detecting comprises estimating a time at which the first satellite is expected to leave the field of view of the user endpoint device;
- estimating, by the processing system, a time at which a second satellite of the non-terrestrial network is expected to enter the field of view of the user endpoint device;
- selecting, by the processing system in response to the time at which the second satellite of the non-terrestrial network is expected to enter the field of view of the user endpoint device, an uplink power for the user endpoint device, wherein the uplink power is selected to be equal to an uplink power at which the user endpoint device is currently transmitting when the time at which the second satellite of the non-terrestrial network is expected to enter the field of view of the user endpoint device is within a predefined threshold period of time of the time at which the first satellite is expected to leave the field of view of the user endpoint device;
- and
- sending, by the processing system to the user endpoint device, an instruction to transmit at the uplink power that is selected.
A non-transitory computer-readable medium storing instructions which, when executed by a processing system including at least one processor, cause the processing system to perform operations, the operations comprising:
- detecting that a first satellite of a non-terrestrial network is moving out of a field of view of a user endpoint device that is currently connected to the non-terrestrial network, wherein the detecting comprises estimating a time at which the first satellite is expected to leave the field of view of the user endpoint device;
- estimating a time at which a second satellite of the non-terrestrial network is expected to enter the field of view of the user endpoint device;
- selecting, in response to the time at which the second satellite of the non-terrestrial network is expected to enter the field of view of the user endpoint device, an uplink power for the user endpoint device, wherein the uplink power is selected to be equal to an uplink power at which the user endpoint device is currently transmitting when the time at which the second satellite of the non-terrestrial network is expected to enter the field of view of the user endpoint device is within a predefined threshold period of time of the time at which the first satellite is expected to leave the field of view of the user endpoint device;
- and
- sending, to the user endpoint device, an instruction to transmit at the uplink power that is selected.
