A method for operating an apparatus capable of Bluetooth and Wireless Local Area Network (WLAN)/WiMAX communications, wherein the apparatus comprises a Bluetooth module for Bluetooth communications, and a WLAN/WiMAX unit comprising a WLAN/WiMAX module for WLAN/WiMAX communications, and a packet traffic arbitration (PTA) module, and the method comprises:
- sending a request for Bluetooth signal transceiving to be performed in a 625 μs time slot from the Bluetooth module to the WLAN/WiMAX unit, wherein the request comprises length information about length of a transceiving time period for Bluetooth signal transceiving, wherein the length of the transceiving time period is shorter than the 625 μs time slot;
- subtracting the transceiving time period from the 625 μs time slot to obtain a residual time period;
- performing an Bluetooth signal transceiving by the Bluetooth module during the transceiving time period of the 625 μs time slot after the WLAN/WiMAX unit grants the request;
- and
- performing an WLAN/WiMAX signal transceiving during said residual time period of the 625 μs time slot in response to the length information by the WLAN/WiMAX unit.
