8.4.3 Maximizing TCP Throughput with Delayed CSI for Mobile

Cloud Services

At time slot t, the system state S

t

is an unobserved random variable.

The wireless network cloud selects the cooperating RRHs and allo-

cates the rate for MCC users, denoted as a

. Denote the end-to-end

throughput of a mobile user u given by Equation (8.15) as a random

variable η
