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 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 frequency that is offset from a reference frequency by a first frequency offset, the first channel signal associated with the second radio device;
measuring the first frequency offset;
determining a received signal strength related to a signal transmitted by the fixed radio apparatus;
determining a second frequency offset, the second frequency offset being determined with respect to the reference frequency, the determination based on the measured first frequency offset and the received signal strength; and
transmitting a second channel signal having a frequency that is offset from the reference frequency by the second frequency offset;
wherein determining the received signal strength includes estimating an uplink received signal strength at the fixed radio apparatus for the second channel signal to be transmitted to the fixed radio apparatus from the first radio device.

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.
