Wyner's soft-handoff network with mixed delay constraints is considered whenneighbouring receivers can cooperate over rate-limited links. Each sourcemessage is a combination of independent "fast" and "slow" bits, where theformer are subject to a stringent decoding delay. Inner and outer bounds on thecapacity region are derived, and the multiplexing gain region is characterizedwhen only transmitters or only receivers cooperate.
