Synchronization for multi-transmission reception point communications in non-terrestrial networks

A method for wireless communication at a network entity, comprising:

• transmitting, to a user equipment (UE) a downlink message indicating a first configuration for a first transmission reception point corresponding to a first cell of a non-terrestrial network and a second configuration for a second transmission reception point corresponding to a second cell of the non-terrestrial network, wherein at least the first transmission reception point and the first cell are moving at a first speed relative to the UE;
• performing, based at least in part on the first configuration, the second configuration, and the first speed, one or more synchronization measurements for synchronizing communications with the first transmission reception point, the second transmission reception point, and the UE;
• and
• receiving one or more uplink messages from the UE in accordance with the one or more synchronization measurements.

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

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive a downlink message indicating a first configuration for a first transmission reception point corresponding to a first cell of a non-terrestrial network and a second configuration for a second transmission reception point corresponding to a second cell of the non-terrestrial network, wherein at least the first transmission reception point and the first cell are moving at a first speed relative to the UE;
• perform, based at least in part on the first configuration, the second configuration, and the first speed, one or more synchronization measurements for synchronizing uplink communications with the first transmission reception point and the second transmission reception point;
• and
• transmit one or more uplink messages to the first transmission reception point, the second transmission reception point, or both, in accordance with the one or more synchronization measurements.
