| 20090245279 | APPARATUS AND METHOD FOR COORDINATING BLUETOOTH AND WIRELESS LOCAL AREA NETWORK (WLAN) AND WIMAX COMMUNICATIONS - The invention provides a method for operating an apparatus capable of Bluetooth and Wireless Local Area Network (WLAN)/WiMAX communications. In one embodiment, the apparatus comprises a Bluetooth module, and a WLAN/WiMAX unit comprising a packet traffic arbitration (PTA) module, and a WLAN/WiMAX module. The Bluetooth module sends a request for Bluetooth signal transceiving to be performed in a Bluetooth time slot to the WLAN/WiMAX unit, wherein the request comprises a length information about length of a transceiving time period for Bluetooth signal transceiving. The Bluetooth module then performs an Bluetooth signal transceiving during the transceiving time period of the Bluetooth time slot after the WLAN/WiMAX unit grants the request. The WLAN/WiMAX unit then performs an WLAN/WiMAX signal transceiveing during a residual time period of the Bluetooth time slot in response to the length information. | 10-01-2009 |

The system comprises a timing generator for generating a timing signal, a timing adjustment device coupled with the timing generator and for adjusting the timing of the timing signal responsive to receipt of an adjustment signal, and a calibration device coupled with the timing adjustment device and arranged to transmit the adjustment signal responsive to a comparison between the timing signal and a reference signal. | 01-14-2010 |
| 20110009060 | Systems and Methods for Reducing Interference Between a Plurality of Wireless Communications Modules - A wireless communications system is provided with a first wireless communications and a second wireless communications. The first wireless communications module transmits or receives a first wireless signal in a first frequency band selected from a first frequency range. The second wireless communications module transmits or receives a second wireless signal in a second frequency band selected from a second frequency range, and adjusts a transmission power of the second wireless signal in response to that a frequency offset between the first frequency band and the second frequency band falls within a predetermined range. | 01-13-2011 |
| 20110053523 | Systems and Methods for Coexistence of a Plurality of Wireless Communications Modules - A wireless communications system is provided with a first wireless communications module, a second wireless communications module, and an RF module. The first wireless communications module transmits or receives a first wireless signal, and the second wireless communications module transmits or receives a second wireless signal. The RF module allocates a first transceiving path and a second transceiving path to the first wireless communications module and the second wireless communications module, respectively, to enable the transmission or reception of the first wireless signal and the second wireless signal at the same time. | 03-03-2011 |
| 20110097998 | System and methods for enhancing coexistence efficiency for multi-radio terminals - A method of scheduling transmitting and receiving communication slots for co-located radio devices is provided. A Bluetooth (BT) device first synchronizes its communication time slots with a co-located radio module, and then obtains the traffic pattern of the co-located radio module. Based on the traffic pattern, the BT device selectively skips one or more TX or RX time slots to avoid data transmission or reception in certain time slots and thereby reducing interference with the co-located radio module. In addition, the BT device generates a co-located coexistence (CLC) bitmap and transmits the CLC bitmap to its peer BT device such that the peer BT device can also skip data transmission or reception in certain time slots affected by the co-located radio module. The skipped time slots are disabled for TX or RX operation to prevent interference and to achieve more energy saving. | 04-28-2011 |
| 20110255414 | Communication Apparatus and Bluetooth ID Packet Recognition Method Thereof - A communication apparatus is provided. The communication apparatus includes an RF module, a down converter coupled to the RF module and a detector coupled to the down converter. The RF module receives an RF signal. The down converter down converts the RF signal in response to a channel select signal to generate a converted signal, wherein the channel select signal controls the down converter to alternately sweep a plurality of scan trains during a scan frame, and each of the scan trains comprises a plurality of channels. The power detector determines whether the RF signal comprises an ID packet according to the converted signal corresponding to the channels of the plurality of scan trains. | 10-20-2011 |
| 20110274080 | SYSTEMS AND METHODS FOR ACTIVITY COORDINATION IN MULTI-RADIO TERMINALS - A wireless communication device is provided with a first radio module and a second radio module inside. The first radio module performs wireless transceiving according to a plurality of first traffic patterns which each indicates allocations of a plurality of first slots for a plurality of forthcoming transmitting or receiving operations, respectively. The second radio module determines an indicator indicating at least one of a plurality of second traffic patterns which each indicates allocations of a plurality of second slots for a plurality of forthcoming transmitting or receiving operations, respectively. Particularly, one or more allocations of the second slots are selectively determined according to the first traffic patterns. Also, the second radio module transmits the indicator to a peer communication device, so that the peer communication device performs transmitting or receiving operations according to the indicator. | 11-10-2011 |
