Abstract: A communications apparatus includes at least two cellular system radio transceivers capable of simultaneously performing transmitting/receiving radio activities in two cellular networks and a control entity. The control entity is coupled to the cellular system radio transceivers, collects radio activity information of the cellular system radio transceivers, determines whether interference will occur or is occurring and which cellular system radio transceiver is an aggressor transceiver and which cellular system radio transceiver is a victim transceiver when the interference occurs according to the radio activity information, and further determines control information according to the radio activity information for controlling the aggressor transceiver or the victim transceiver to mitigate the interference. The aggressor transceiver is the cellular system radio transceiver having the transmitting radio activity that will interfere or interferes with the receiving radio activity of the victim transceiver.

Abstract: A communications apparatus. The RF signal processing device is capable of supporting carrier aggregation and configured to process RF signals. The baseband signal processing device is configured to process baseband signals. The processor is configured to control operations of the RF signal processing device and the baseband signal processing device. The processor further receives a power control signal from a peer communications apparatus, obtains an assigned transmission power which is assigned by the peer communications apparatus for the communications apparatus to transmit a reference signal according to information carried in the power control signal, determines a spectral efficiency estimation value of the communications apparatus and directs the RF signal processing device to transmit the reference signal with a reduced transmission power which is smaller than the assigned transmission power when the spectral efficiency estimation value is smaller than a predetermined threshold.
