A frame timing controller includes a timer, a frame timing control unit, and a frame pointer processing circuit. The timer is arranged to generate a timer value according to a first clock signal with a first clock frequency. The frame timing control unit is for triggering at least a receiver to start receiving transmitted information of a base station according to at least a frame pointer and the timer value, wherein the receiver processes an input signal to generate first samples at a first sampling rate corresponding to a sampling clock frequency and processes the first samples to generate an output signal including second samples at a second sampling rate corresponding to a second clock frequency of a second clock signal different from the sampling clock frequency. The frame pointer processing circuit is for generating and updating the frame pointer according to the output signal of the receiver.

Frame timing controller and frame timing control method for triggering at least receiver in mobile station to start receiving transmitted information of base station by referring to at least frame pointer

An apparatus for performing a scan procedure according to an orthogonal frequency division multiple access (OFDMA) signal and a mobile station comprising the same are provided. The characteristic of the apparatus is that it comprises two FIT input buffers. In a first period of a downlink subframe, the first FFT input buffer is used for data transmission. In a second period of the downlink subframe, the second FFT input buffer is used for storing more than one OFDMA sample in advance for further processing. In a third period of an uplink subframe, the stored OFDMA samples can be used to generate a refined frame boundary and calculates a CINR value of each of a plurality of neighboring base stations. Therefore, the apparatus and the MS can perform the scan procedure without downgrading the network efficiency.

A communication apparatus is provided. A power amplifier is coupled to an antenna and switched on or off according to a control signal. A baseband processing module is coupled to the power amplifier and a radio transceiver module, receives a bit stream comprising information indicating corresponding transmitting time and sub-carrier frequencies of up-link messages via the radio transceiver module, processes the bit stream to obtain a map profiling allocations of the up-link messages, prepares the up-link messages to be transmitted according to the map, and generates the control signal according to the map. Within a data frame period, when there is no up-link message to be transmitted during a up-link time interval, the power amplifier is switched off in response to the control signal during the up-link time interval.
