Abstract: A communications apparatus includes a radio transceiver and a processor. The radio transceiver is configured for transmitting or receiving wireless radio frequency signals to or from a peer device. The processor determines whether re-synchronization in a communication mode with the peer device is required according to a determination rule. When the re-synchronization is required, the processor transmits a message to the peer device via the radio transceiver to trigger a re-synchronization procedure. The processor determines whether the re-synchronization is required in a connected mode.

Abstract: A wireless communications device includes a radio frequency (RF) module and a baseband chip. The baseband chip is configured to initiate a mobile originated (MO) call through the RF module with a first subscriber identity card when the RF module is occupied by performing a packet switched (PS) data service with a second subscriber identity card, arbitrate a first protocol stack handler to suspend or terminate the PS data service associated with the second subscriber identity card in response to initiating the MO call associated with the first subscriber identity card, and arbitrate a second protocol stack handler to make the MO call associated with the first subscriber identity card when the PS data service associated with the second subscriber identity card is suspended or terminated.

Abstract: Various solutions for selecting large-bandwidth cell with respect to user equipment and network apparatus in mobile communications are described. An apparatus may measure a first cell. The apparatus may measure a second cell. The apparatus may add an offset value to a measurement report of the second cell. The apparatus may transmit the measurement report of the second cell to a serving cell. A second bandwidth of the second cell may be greater than a first bandwidth of the first cell.
