Embodiment Construction

[0031] Some wireless communication systems may operate in the millimeter wave (mmW) frequency range (eg, 28GHz, 40GHz, 60GHz, etc.). In such mmW systems, signal processing techniques such as beamforming can be used to coherently combine energy and overcome path loss at these frequencies. Wireless communication links enabled by beamforming can be associated with highly directional narrow beams (e.g., “pencil beams”), minimizing inter-link interference, and provide high-bandwidth links between them.

[0032] Wireless communication systems also utilize backhaul links as connections between the core network and access nodes within the wireless communication network. However, due to the widespread deployment of access nodes in a given area, the cost of installing a wired backhaul link to each access node within the network is prohibitive. Therefore, a cellular radio access technology (RAT) can be used to provide a backhaul link between multiple access nodes and the core network. ...

Abstract

The use of a radio access technology (RAT) may enable wireless communication using one or more node functions at a wireless node, such as a base station or access node. Additionally, multiple wirelessnodes may communicate in a network using a schedule that is aligned with a frame structure. For example, a wireless node may establish a link with different wireless nodes using a RAT that supports asynchronized frame structure, such as a millimeter wave (mmW) RAT. The wireless nodes may instantiate one or more node functions, such as an access node function (ANF) and a user equipment function (UEF). The wireless nodes may then communicate according to active and suspended modes using the node functions, where the communication is based on a schedule aligned with the frame structure.
