Abstract
Mobile communication with non-terrestrial networks can be impacted by signal degradation and link budget constraints. These impacts may result from factors including path loss over satellite distances and the limited transmit power of a mobile device. To address these impacts, multiple, physically distinct user devices can be coordinated to function as a distributed antenna array. A primary computing device, for example, a smartphone, laptop, or tablet, can orchestrate the operation of one or more secondary devices, such as a smartwatch, wearable device, or another smartphone. This orchestration can involve frequency and phase synchronization between the devices and spatial optimization of their relative placement, which may be guided by on-board sensors, such as accelerometers or gyroscopes. The coherent combination of signals from the array's antenna elements can create a larger effective aperture, which may improve the communications link budget and the reliability of establishing a satellite communications link.
