Random User Activity with Mixed Delay Traffic

Résumé

This paper analyses the multiplexing gain (MG) achievable over a general interference network with random user activity and random arrival of mixed-delay traffic. The mixeddelay traffic is composed of delay-tolerant traffic and delaysensitive traffic where only the former can benefit from receiver cooperation since the latter is subject to stringent decoding delays. Two setups are considered. In the first setup, each active transmitter always has delay-tolerant data to send and delaysensitive data arrival is random. In the second setup, both delaytolerant and delay-sensitive data arrivals are random, and only one of them is present at any given transmitter. The MG regions of both setups are completely characterized for Wyner's softhandoff network. For Wyner's symmetric linear and hexagonal networks inner bounds on the MG region are presented.
