Abstract
Disclosed are techniques for wireless communication. In some aspects, a user equipment (UE) may detect one or more events during a communication with a terrestrial network (TN). The UE may perform a positioning operation to determine a positioning fix based on the one or more events. The UE may establish a communication with a non-terrestrial network (NTN) based on the one or more events and the positioning fix.
Claims30
A user equipment (UE), comprising:
- one or more memories;
- one or more transceivers;
- and
- one or more processors communicatively coupled to the one or more memories and the one or more transceivers, the one or more processors, either alone or in combination, configured to:
- detect one or more events during a communication with a terrestrial network (TN);
- perform a positioning operation to determine a positioning fix based on the one or more events;
- and
- establish a communication with a non-terrestrial network (NTN) based on the one or more events and the positioning fix.
A serving cell of a terrestrial network (TN), comprising:
- one or more memories;
- one or more transceivers;
- and
- one or more processors communicatively coupled to the one or more memories and the one or more transceivers, the one or more processors, either alone or in combination, configured to:
- transmit, via the one or more transceivers, to a user equipment (UE), a configuration associated with one or more events to trigger the UE to perform a positioning operation to determine a positioning fix based on the one or more events;
- determine that the UE is moving out of a coverage area of the TN;
- and
- transmit, via the one or more transceivers, to the UE, a command to switch a communication from the TN to a non-terrestrial network (NTN) based on a determination that the UE is moving out of the coverage area of the TN.
A method of wireless communication performed at a user equipment (UE), comprising:
- detecting one or more events during a communication with a terrestrial network (TN);
- performing a positioning operation to determine a positioning fix based on the one or more events;
- and
- establishing a communication with a non-terrestrial network (NTN) based on the one or more events and the positioning fix.
A method of wireless communication performed at a serving cell of a terrestrial network (TN), comprising:
- transmitting, to a user equipment (UE), a configuration associated with one or more events to trigger the UE to perform a positioning operation to determine a positioning fix based on the one or more events;
- determining that the UE is moving out of a coverage area of the TN;
- and
- transmitting, to the UE, a command to switch a communication from the TN to a non-terrestrial network (NTN) based on a determination that the UE is moving out of the coverage area of the TN.
