High-capacity scalable integrated wireless backhaul for broadband access networks

Abstract

The invention provides a method and system for adaptive point-to-point communication between a wireless communication system and a non-wireless backhaul communication system. The wireless physical layer and the wireless media-access-control layer collectively include a set of parameters, which are adaptively modified by base station controllers in multiple cells of the wireless communication system for intercommunication among those multiple cells. The IP layer and QoS parameters for communication between a selected base station controller and the non-wireless backhaul communication system collectively include a second set of parameters, which are adaptively modified for intercommunication between that selected base station controller and the non-wireless backhaul communication system. The combination of wireless communication and non-wireless communication over the entire channel includes adaptive modification of parameters for the IP layer and QoS to optimize backhaul communication between customer premises equipment and the backhaul network.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of U.S. application Ser. No. 09 / 604,784 filed Jun. 26, 2000 (Attorney Docket number 164.1010.01), hereby incorporated by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] This invention relates to wireless communication systems, such as those including integrated backhaul. [0004] 2. Related Art [0005] Wireless communication systems include sending information between a sender and a receiver using a wireless communication link. In wireless communication, the sender modulates information onto a wireless communication channel (such as a frequency band reserved for wireless communication between the sender and the receiver), and the receiver demodulates that information from the wireless communication channel (so as to recover the original information). Known wireless communication systems often use a cell structure, in which within each cell a BSC (base station controller) com...

AI Technical Summary

Benefits of technology

"The invention provides a method and system for adaptive point-to-point communication between a wireless communication system and a non-wireless backhaul communication system. This allows for seamless connectivity and efficient communication among multiple cells in the wireless communication system. The invention also adapts parameters for the physical layer and MAC layer to optimize intercell or intracell communication without excessive interference. Additionally, the invention adapts parameters for the IP layer and QoS administration of communication to optimize backhaul communication between customer premises equipment and the non-wireless backhaul communication system. The invention is applicable to various types of communication where characteristics of the communication link are subject to change."

Problems solved by technology

One problem with known systems is the need to provide integrated backhaul connectivity between the wireless communication system and a non-wireless communication system.

However, attempts to integrate backhaul connectivity with known systems would suffer from similar drawbacks to those that are common to internal communication within wireless communication systems; these would include drawbacks described in the Incorporated Disclosures (see “Related Applications” below).

As a result, selection of a single set of such physical characteristics, even when physical conditions of the lines of sight between the first cell and the second cell are known, can result in relatively ineffective or inefficient communication between cells.
