Claim:
1. A method for assigning backhaul links in a cooperative wireless network including a control unit (CU) connected to a set of access points (APs) by a set of backhaul links, and wherein the APs are connected to an end user by wireless channels and the APs obtain a message via the set of backhaul links that are unreliable, comprising: accessing a memory of the CU to obtain a stored long term reliability for each backhaul link, the CU determines a reliability of each backhaul link using the stored long term reliability for each backhaul link, to produce a set of reliabilities; accessing the memory of the CU to obtain stored locations of the end user, in particular, a distance for each AP to the end user, the CU determines a distance between each AP and the end user using the stored locations of the end user, to produce a set of distances; determining, by the CU, using the set of reliabilities and the set of distances, probabilities of successful reception of the message transmitted from the CU to the end user via the backhaul links and the wireless channels, wherein the backhaul links are configured to be assigned to any AP in the set of APs based on an overall probability of successful reception of the message by the end user; and assigning, by the CU, the backhaul links according to the probabilities of successful reception of the message by the end user.
