  Wyner's soft-handoff network is considered where transmitters simultaneously
send messages of enhanced mobile broadband (eMBB) and ultra-reliable
low-latency communication (URLLC) services. Due to the low-latency
requirements, the URLLC messages are transmitted over fewer channel uses
compared to the eMBB messages. To improve the reliability of the URLLC
transmissions, we propose a coding scheme with finite blocklength codewords
that exploits dirty-paper coding (DPC) to precancel the interference from eMBB
transmissions. Rigorous bounds are derived for the error probabilities of eMBB
and URLLC transmissions achieved by our scheme. Numerical results illustrate
that they are lower than for standard time-sharing.
