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: Exemplary embodiments of the present disclosure provide several packet scheduling methods and communication apparatuses using the same. The packet scheduling method is different from the conventional packet scheduling method, since it does not schedule the sleep interval of the mobile subscriber station based upon the connections as the conventional packet scheduling method. Instead, the packet scheduling method considers the quality of service, and aggregates the data bursts to the frame corresponding to the frame index to which the data bursts are shifted based upon the individual packet, such that a total time length of the sleep intervals of the mobile subscriber station is maximized, and the maximum power saving efficiency is obtained correspondingly.
