Abstract
Systems and methods for enabling a wireless backhaul network between access points (APs) in a wireless network are provided. In an embodiment, the wireless backhaul network is enabled using a Massive Multiple Input Multiple Output (MIMO) radio access technology (RAT). In another embodiment, the wireless backhaul network is established using the same RAT as used by the APs to serve user devices, and can utilize the same time and frequency resources used for user communication.

17. An Access Point (AP), comprising:
-
a Massive Multiple Input Multiple Output (M-MIMO) antenna array; and a processor configured to; inspect outgoing backhaul traffic to determine whether the outgoing backhaul traffic belongs to a first category or a second category; if the outgoing backhaul traffic belongs to the first category, transmit the outgoing backhaul traffic, using a first subset of the M-MIMO antenna array and a first radio access technology (RAT), over a first wireless backhaul channel; and if the outgoing backhaul traffic belongs to the second category, transmit the outgoing backhaul traffic, using a second subset of the M-MIMO antenna array and a second RAT, over a second wireless backhaul channel. - View Dependent Claims (18, 19, 20)
