Abstract
A user equipment (UE) receives, from a non-terrestrial network (NTN), a measurement configuration that indicates a timing pattern for inter-frequency measurement, the timing pattern including a measurement gap of a certain duration. The UE receives, from the NTN, a synchronization signal during the measurement gap in accordance with the timing pattern, performs a measurement of the synchronization signal; and transmits, to the NTN, an indication related to the measurement gap. For example, the indication may be a request to terminate early the measurement gap.
Claims15
A method for synchronization signal measurement implemented in a user equipment, the method comprising:
- receiving, by the UE from a non-terrestrial network, a measurement configuration that indicates a timing pattern for inter-frequency measurement, the timing pattern having a measurement gap of a certain duration;
- receiving, by the UE from the NTN, a synchronization signal during the measurement gap in accordance with the timing pattern;
- performing, by the UE, a measurement of the synchronization signal;
- and
- transmitting, by the UE to the NTN, an indication related to the measurement gap.
A user equipment UE, comprising:
- a transceiver;
- and
- processing hardware configured to implement a method that includes:
- receiving, by the UE from the NTN, a synchronization signal during the measurement gap in accordance with the timing pattern;
- performing, by the UE, a measurement of the synchronization signal;
- and
- transmitting, by the UE to the NTN, an indication related to the measurement gap.
A method for configuring synchronization signal measurement in a user equipment UE, the method implemented in a serving non-terrestrial network NTN, node and comprising:
- transmitting, by the NTN node to a UE, a measurement configuration that indicates a timing pattern for inter-frequency measurement at the UE, the timing pattern having a measurement gap of a certain duration;
- receiving, by the NTN node from the UE, an indication related to the measurement gap;
- and
- modifying, by the NTN node, the timing pattern in accordance with the received indication.
A non-terrestrial network NTN, node comprising:
- a transceiver, and
- processing hardware and configured to implement a method of including:
- transmitting, by the NTN node to a UE, a measurement configuration that indicates a timing pattern for inter-frequency measurement at the UE, the timing pattern having a measurement gap of a certain duration;
- receiving, by the NTN node from the UE, an indication related to the measurement gap;
- and
- modifying, by the NTN node, the timing pattern in accordance with the received indication.
