Abstract:
Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support non-terrestrial network (NTN) signaling between both terrestrial and non-terrestrial devices. A user equipment (UE) supporting such NTN signaling may receive a downlink message indicating a first configuration for a first transmission reception point corresponding to a first cell of the NTN, and a second configuration for a second transmission reception point corresponding to a second cell of the NTN. The UE may then perform one or more synchronization measurements to synchronize uplink communications with the first transmission reception point and the second transmission reception point and in order to perform multi-transmission reception point communications in the NTN. The UE may then transmit one or more uplink messages to the first transmission reception point, to the second transmission reception point, or both, in accordance with the one or more synchronization measurements.
