Assignment of Backhaul Resources in Cooperative Wireless Networks

摘要

A method assigns 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. A reliability of each backhaul link is determined to produce a set of reliabilities. A distance between each AP and the end user is determined to produce a set of distances. Using the set of reliabilities and the set of distances, probabilities of successful reception of a message transmitted from the CU to the end user via the backhaul links and the wireless channels are determined. Then, the backhaul links are assigned according to the probabilities of successful reception of the message by the end user.

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, comprising steps:
determining a reliability of each backhaul link to produce a set of reliabilities; determining a distance between each AP and the end user to produce a set of distances; determining, using the set of reliabilities and the set of distances, probabilities of successful reception of a message transmitted from the CU to the end user via the backhaul links and the wireless channels; and assigning the backhaul links according to the probabilities of successful reception of the message by the end user, wherein the steps are performed by the CU.
