We present upper and lower bounds on the per-user multiplexing gain (MG) of
Wyner's circular soft-handoff model and Wyner's circular full model with
cognitive transmitters and receivers with cache memories. The bounds are tight
for cache memories with prelog μ≥2/3D in the soft-handoff model and for
μ≥D in the full model, where D denotes the number of possibly
demanded files. In these cases the per-user MG of the two models is 1+μ/D,
the same as for non-interfering point-to-point links with caches at the
receivers. Large receiver cache-memories thus allow to completely mitigate
interference in these networks.Comment: Submitted to ITW 2016 in Cambridg
