Abstract :
We propose a novel method for improving wireless network capacity by resorting to a so-called "multi-cell access" (MCA) scheme. An MCA scheme is reminiscent of the conventional multiple access problem in multi-user networks. However, in an MCA scheme cells (rather than users) compete for access. Furthermore, an example of such a scheme is introduced whereby a cell obtains a credit that is a function of the channel gain of its scheduled user, and it is allowed to transmit with a probability that is computed based on the credit value. The network capacity under this scheme is analyzed and we propose an optimization method in the case where the probability distribution for access is binary
