An apparatus for coordinating radio activities in different radio access technologies (RATs) is provided. A first RAT module performs a first channel activity, related to a first RAT, for transmitting or receiving information to or from a first cellular network by using an antenna, and requests that a measurement activity, related to the first RAT, is to be performed for measuring signal power of a serving cell and/or at least one neighbor cell in the first cellular network by using the antenna. A second RAT module requests that a second channel activity, related to a second RAT, is to be performed for transmitting or receiving information to or from a second cellular network by using the antenna. An arbiter schedules performance of the measurement activity between the first and second channel activities.

A communication apparatus is provided. A processor receives a measurement control message carrying information about a filtering coefficient via a radio transceiver module, periodically measures signal quality of at least one cell to obtain a plurality of measurement results, periodically filters the measurement results according to a first measurement period to obtain a plurality of filtered results, and determines whether to transmit a measurement report to a system controller in the wireless communication network according to the filtered results. The filtering coefficient is assigned by the system controller to filter the measurement results according to a second measurement period. The second measurement period is longer than the first measurement period

An apparatus for coordinating radio activities of different radio access technologies (RATs) includes a first RAT module, a second RAT module and an arbiter. The first RAT module receives and transmits radio frequency (RF) signals from and to a first cellular network through an antenna, and synchronizes transceiving timings with the first cellular network using a first clock. The second RAT module receives and transmits RF signals from and to a second cellular network through the antenna, and synchronizes transceiving timings with the second cellular network using a second clock. The arbiter coordinates a first radio activity requested by the first RAT module and a second radio activity requested by the second RAT module to avoid radio activity collision by using a third clock.

An automatic gain control method used in a wireless receiver is disclosed. The method comprise the following steps: Receiving a first frame, amplifying a RF signal corresponding to the first frame with a gain value and down converting the RF signal to generate a baseband signal. Updating the gain value according to the power level of the baseband signal corresponding to the first frame, then using the updated gain value to amplify the RF signal corresponding to a second frame when receiving the second frame. Determining whether a first signal block is in the discontinuous transmission mode or not, wherein the first frame belongs to the first signal block. And resuming the gain value according to the power level of the baseband signal corresponding to a third frame if the first signal block is in the discontinuous transmission mode.
