Problems solved by technology

For communication between UEs with relays, the problem will be even more serious, because if the identities associated with each link cannot be at the same time, it will cause the listener to associate the unupdated identity with the updated identity, so as to grasp the new identity. The identity of the multi-node coordination makes the problem more complicated
