US 8,913,962 B2 · Systems and methods for reducing interference between a plurality of wireless communications modules

Abstract

A wireless communications includes a first wireless communications and a second wireless communications. The first wireless communications module transmits or receives a first wireless signal in a first frequency band selected from a first frequency range. The second wireless communications module transmits or receives a second wireless signal in a second frequency band selected from a second frequency range, and adjusts a transmission power of the second wireless signal in response to that a frequency offset between the first frequency band and the second frequency band falls within a predetermined range. The first wireless communications module is further configured to determine an in-band range in the overlapping part of the first and second frequency ranges, and a transmission power of the second wireless signal is adjusted in response to a frequency offset between the first frequency band and the second frequency band.

Dependent claims

A wireless communications system, comprising:

a first wireless communications module configured to transmit or receive a first wireless signal in a first frequency band selected from a first frequency range;
and
a second wireless communications module configured to transmit or receive a second wireless signal in a second frequency band selected from a second frequency range which overlaps at least in part with the first frequency range;
wherein the first wireless communications module is further configured to determine an in-band range in the overlapping part of the first and second frequency ranges, wherein the in-band range corresponds to a frequency range where a received first wireless signal and a received second wireless signal experience in-band interference caused by a transmitted second wireless signal and a transmitted first wireless signal, respectively;
and
wherein a transmission power of the second wireless signal is adjusted in response to a frequency offset between the first frequency band and the second frequency band falling within the in-band range.
