  Non-terrestrial networks (NTNs) will complement terrestrial networks (TNs) in
5G and beyond, which can be attributed to recent deployment and standardization
activities. Maximizing the efficiency of NTN communications is critical to
unlock its full potential and reap its numerous benefits. One method to make
communications more efficient is by the usage of multi-connectivity (MC), which
allows a user to connect to multiple base stations simultaneously. It is
standardized and widely used for TNs, but for MC to be used in the NTN
environment, several challenges must be overcome. In this article, challenges
related to MC in NTNs are discussed, and solutions to the identified challenges
are proposed.
