Method for suppressing transmission noise comprised in received downlink signal and communications apparatus utilizing the same
First Claim
1. A method for suppressing transmission noise comprised in a plurality of downlink signals received by one of a first radio module or a second radio module comprised in a communications apparatus, wherein the transmission noise is generated when the other one of the first radio module or the second radio module is processing a plurality of uplink signals to be transmitted, the method comprising:
- receiving a plurality of first signals and a plurality of second signals, wherein the first signals and the second signals are the downlink signals respectively received via different antennas of the one of the first radio module or the second radio module, or the first signals are the downlink signals received by the one of the first radio module or the second radio module and the second signals are a portion of the uplink signals provided by the other one of the first radio module and the second radio module; and
processing the plurality of first signals and the plurality of second signals to cancel transmission noise comprised in the plurality of downlink signals.

5. A communications apparatus, comprising:
-
a first radio module, providing a first wireless communications service and communicating with a first communications device in compliance with a first protocol; and a second radio module, providing a second wireless communications service and communicating with a second communications device in compliance with a second protocol, wherein the second protocol is different from the first protocol; wherein a transmitting signal of the first radio module is drawn, by a coupling path, to a down-conversion circuit to be down-converted to a frequency band utilized by the second radio module. - View Dependent Claims (6, 7, 8)
