20130252614 | METHODS FOR PREFERABLY CAMPING ON AND STAYING IN A CELL BELONGING TO A HIGH DATA TRANSMISSION THROUGHPUT RAT AND COMMUNICATIONS APPARATUSES UTILIZING THE SAME - A communications apparatus includes a processor coupled to at least one RF transceiver and at least one baseband processing device and capable of communicating with a first wireless network belonging to a first RAT and a second wireless network belonging to a second RAT having a higher data transmission throughput than the first RAT. A first processor logic unit of the processor performs an enhanced cell search procedure via the RF transceiver to find one or more cell(s) belonging to the second RAT having stronger signal strength and/or better signal quality than a predetermined threshold, which are not included in a broadcast neighbor cell list. A second processor logic unit of the processor determines a suitable cell from among the cell(s) and performs a cell reselection procedure to camp on the suitable cell. | 09-26-2013 |

20160142027 | AMPLIFIER AND RELATED METHOD - An amplifier applicable to an intra-band non-contiguous carrier aggregation (NCCA) band includes a first amplifier circuit and a second amplifier circuit. The NCCA band includes at least a primary component carrier (PCC) channel and a secondary component carrier (SCC) channel not adjacent to each other. The first amplifier circuit receives a first input signal, and generates a first output signal for undergoing down-conversion of one of the PCC channel and the SCC channel. The second amplifier circuit receives at least one second input signal, and generates a second output signal for undergoing down-conversion of another of the PCC channel and the SCC channel. The at least one second input signal received by the second amplifier circuit is provided by the first amplifier circuit according to the first input signal. | 05-19-2016 |
