METHOD AND SYSTEM FOR IMPROVING ADJACENT CHANNEL REJECTION PERFORMANCE IN A WIRELESS NETWORK
First Claim
1. A method of improving adjacent channel rejection performance in a wireless signal used by a first radio device in a mobile radio network, the mobile radio network further including a second radio device and a fixed radio apparatus, the method being performed by the first radio device and comprising:
- receiving a first channel signal having a first frequency offset with respect to a reference frequency, the first channel signal being associated with the second radio device;
measuring the first frequency offset;
determining a second frequency offset for a second channel signal, the second frequency offset being determined with respect to the reference frequency, the determination being based on the measured first frequency offset; and
transmitting the second channel signal with the second frequency offset.

Abstract
Methods and systems for improving adjacent channel rejection performance in a wireless signal by a radio device in a mobile network. In one embodiment, a mobile radio network includes a first radio device (e.g., a subscriber), a second radio device, and a fixed radio apparatus (e.g., a base station or repeater). The first radio device receives a first channel signal having a first frequency offset with respect to a reference frequency. The first channel signal is associated with the second radio device. The first radio device measures the first frequency offset, determines a second frequency offset for a second channel signal, and transmits the second channel signal with the second frequency offset.
