1. 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 the second wireless communications module is further configured to determine whether a frequency offset between the first frequency band and the second frequency band falls within the in-band range, and adjust a transmission power of the second wireless signal in response to the frequency offset falling within the in-band range.

Abstract
A wireless communications system is provided with 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.

9. A method for reducing interference between a plurality of wireless communications modules in a wireless communications device, comprising:
-
transmitting or receiving a first wireless signal in a first frequency band selected from a first frequency range by a first wireless communications module, and transmitting or receiving 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, by a second wireless communications module; determining 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; determining whether a frequency offset between the first frequency band and the second frequency band falls within the in-band range; and adjusting a transmission power of the second wireless signal in response to the frequency offset falling within the in-band range. - View Dependent Claims (10, 11, 12, 13, 14)
