METHOD AND SYSTEM FOR INTERFERENCE MANAGEMENT IN A SPECTRUM SHARED BY WAN AND FEMTO CELLS
First Claim
1. A method for interference management in a frequency spectrum shared by a WAN macro cell and a femto cell, comprising:
- detecting a WAN access terminal (AT) in a coverage area of the femto cell;
accessing a control message sent by a WAN access point (AP) to the WAN AT;
determining a first resource of the spectrum that the WAN AT will use to communicate with the WAN AP based at least in part on the control message; and
assigning a second resource of the spectrum to a femto AT in the coverage area based at least in part on the determined first resource.

Abstract
Devices and methods are provided for adapting to interference in a spectrum shared by a WAN macro cell and a femto cell. In particular, described herein are techniques for adapting to the presence of a jamming WAN access terminal (AT) by avoiding or selectively utilizing those bandwidth portions jammed by the WAN AT/AP. For example, the technique may involve intercepting a control message from the WAN AP to the WAN AT, and determining a spectrum resource that the WAN AT will use to communicate with the WAN AP based at least in part on information (e.g., a Cell Radio Network Temporary Identifier, a Media Access Control Identifier, etc.) in the control message.
