Detailed ways

The preferred embodiments disclosed in the present invention are discussed below. Although the description is based on the spirit of the present invention with the following examples, it is not intended to limit the present invention to these examples. The examples given in the present invention are only used for illustration of this specification, and are not intended to limit the viewpoint of the present invention.

FIG. 1 is a schematic diagram of an embodiment of an electronic device 10 with a Bluetooth module and a wireless network module according to the present invention. The electronic device 10 has a Bluetooth module 11 , a logic circuit 12 , a WiFi module 13 and a Worldwide Interoperability for Microwave Access (WiMAX) module 14 . The logic circuit 12 is used for selectively electrically connecting the Bluetooth module 11 to the WiFi module 13 or the WiMAX module 14 . In this embodiment, the electronic device 10 can operate in a first operation mode and a second operation mode. In the first operation mode, the logic circuit 12 electrically connects the Bluetooth module 11 to the WiFi module 13, so that the Bluetooth module 11 and the WiFi module 13 can use an existing packet arbitration (Packet Traffic Arbitration; PTA) mechanism to share the radio frequency Components (not shown), such as components such as antennas, power amplifiers, or low noise amplifiers. In the second operation mode, the logic circuit 12 electrically connects the Bluetooth module 11 to the WiMAX module 14, so that the Bluetooth module 11 and the WiMAX module 14 can use the coexistence mechanism of the present invention to share radio frequency components (not shown), such as: antenna, Components such as power amplifiers or low noise amplifiers. The WiFi module 13 and the WiMAX module 14 cannot operate at the same time. The coexistence mechanism (ie, the packet arbitration mechanism) of the WiFi module 13 and the Bluetooth module 11 is already in the prior art, and will not be repeated here. This embodiment will focus on the description of the coexistence mechanism of the WiMAX module 14 and the Bluetooth module 11 .

In this embodiment, the logic circuit 12 will determine whether to enable or not according to the priority of the Bluetooth module 11, the priority of the WiMAX module 14, and whether the Bluetooth module 11 is in the receiving (RX) mode or the transmitting (TX) mode at this time. WiMAX module 14 and/or Bluetooth module 11 . The following explains the meaning of the signals in Figure 1:

W_Active: This signal will be set to 0 or 1 according to whether the data received or transmitted by the WiMAX module 14 needs to be protected and the priority status of the Bluetooth module 11. If the data transmitted by the WiMAX module 14 needs to be protected (that is, when the signal WIMAX_COEXISTENCE_PROTECTION is 1), and the priority of the Bluetooth module 11 is lower than that of the WiMAX module 14 (that is, when the signal BT_PRI_DATA is 0), the signal W_Active is set to 1. If the data transmitted by the WiMAX module 14 does not need to be protected (ie, when the signal WIMAX_COEXISTENCE_PROTECTION is 0), or the priority of the Bluetooth module 11 is higher than that of the WiMAX module 14 (ie, when the signal BT_PRI_DATA is 1), the signal W_Active is set to 0. In this embodiment, when the signal W_Active is set to 1, the power amplifier (not shown) in the bluetooth module 11 for transmitting data will be de-enabled, so that the bluetooth module 11 cannot transmit data. It should be noted that this embodiment takes the WiMAX module 14 as an example for illustration, but the signal W_Active can also be used by the WiFi module 13 . Because only one of the WiFi module 13 and the WiMAX module 14 is enabled at the same time, the WiFi module 13 can also use the signal W_Active to realize the coexistence mechanism of the WiFi module 13 and the Bluetooth module 11 .

BT_PRI_DATA: This signal is used to indicate the priority of the data packets received or transmitted by the Bluetooth module 11 . In this embodiment, when the priority of the data packet received or transmitted by the Bluetooth module 11 is higher than that of the WiMAX module 14, the signal BT_PRI_DATA is set to 1; when the priority of the Bluetooth module 11 is lower than that of the WiMAX module 14, the signal BT_PRI_DATA is set to 1 Set to 0.

BT_PA_ON: This signal is used to indicate that the Bluetooth module 11 is in the receiving mode or the transmitting mode. In this embodiment, when the Bluetooth module 11 is in the receiving mode, the signal BT_PA_ON is set to 0, and when the Bluetooth module 11 is in the transmitting mode, the signal BT_PA_ON is set to 1.

WIMAX_COEXISTENCE_PROTECTION: This signal is used to indicate that the data received or transmitted by the WiMAX module 14 needs to be protected at this time. When the data received or transmitted by the WiMAX module 14 does not need to be protected, the signal WIMAX_COEXISTENCE_PROTECTION is set to 0; when the data received or transmitted by the WiMAX module 14 needs to be protected, the signal BT_PA_ON is set to 1. In an embodiment of the present invention, when the Bluetooth module 11 has a higher priority than the WiMAX module 14 (that is, when the signal BT_PRI_DATA is set to 1) and is in the transmission mode, if the WiMAX module 14 is in the state of receiving data and the received The data needs to be protected (that is, when the signal WIMAX_COEXISTENCE_PROTECTION is set to 1), then the logic circuit 12 controls the WiMAX module 14 to suspend receiving data at this time, and at this time the WiMAX module 14 can first send a request (request), please transmit the data to the base station Temporarily stop transferring data. Or when the priority of the Bluetooth module 11 is higher than that of the WiMAX module 14 (that is, when the signal BT_PRI_DATA is set to 1) and is in the transmission mode, if the WiMAX module 14 is in the state of transmitting data and the transmitted data needs to be protected ( That is, when the signal WIMAX_COEXISTENCE_PROTECTION is set to 1), the logic circuit 12 controls the WiMAX module 14 to suspend data transmission at this time. At this time, the WiMAX module 14 will keep the untransmitted data until the logic circuit 12 enables the WiMAX module 14 again. Then send the unfinished data from the previous time.

PA_EN_WIMAX_CONTROL: This signal is used to indicate whether the WiMAX module 14 is in the transmission mode at this time. When the WiMAX module 14 is in the transmission mode, the signal PA_EN_WIMAX_CONTROL is set to 1, and when the WiMAX module 14 is not in the transmission mode, the signal PA_EN_WIMAX_CONTROL is set to 0.

PA_EN: This signal is used to indicate whether the power amplifier (power amplifier, PA) of the WiMAX module 14 is enabled at this time.

In this embodiment, if the priority of the Bluetooth module 11 is higher than that of the WiMAX module 14, the WiMAX module 14 is inactive. When the bluetooth module 11 is in the transmission mode, the WiMAX module 14 can be disabled by reverse-enabling the power amplifier or the baseband chip in the WiMAX module 14 . When the Bluetooth module 11 is in the receiving mode, if the WiMAX module 14 is also in the receiving mode, the Bluetooth module 11 and the WiMAX module 14 can be operated simultaneously. However, in another embodiment, in order to ensure that the Bluetooth module 11 is not disturbed when receiving data, the WiMAX module 14 can still be set to be inactive.

When the priority of the Bluetooth module 11 is lower than that of the WiMAX module 14 , whether the Bluetooth module 11 can be enabled or not depends on whether the signal W_Active is set to 1 or not. If the signal W_Active is set to 0, it means that the data received or transmitted by the WiMAX module 14 does not need to be protected (that is, when the signal WIMAX_COEXISTENCE_PROTECTION is set to 0), then the Bluetooth module 11 can transmit or receive data. If the signal W_Active is set to 1, it means that the data received or transmitted by the WiMAX module 14 needs to be protected (that is, when the signal WIMAX_COEXISTENCE_PROTECTION is set to 1), so the Bluetooth module 11 is not allowed to transmit or receive data, that is to say The bluetooth module 11 is disabled and does not act.

For a clearer illustration, please refer to Figure 2. FIG. 2 is a schematic diagram of another embodiment of an electronic device with a Bluetooth module and a wireless network module according to the present invention. The WiMAX module 24 includes a WiMAX baseband chip 25 , a WiMAX radio frequency module 26 and a power amplifier 27 . The WiMAX module 24 is further coupled to the first antenna 28 to transmit or receive data through the first antenna 28 . In this embodiment, the first logic unit 22 and the second logic unit 23 can be included in the logic circuit 12 of FIG. 1 .

In this embodiment, the Bluetooth module 21 receives or transmits data through the second antenna 29 . But in another embodiment, the Bluetooth module 21 and the WiMAX module 24 can receive data through the first antenna 28 and a switch (not shown). In addition, because the area occupied by the power amplifier and the power consumed are large, the Bluetooth module 21 and the WiMAX module 24 can also be designed to use the same power amplifier, such as the power amplifier 27 .

The second logic unit 23 determines whether to make the Bluetooth module 21 active according to the priority of the Bluetooth module 21 and whether the data received or transmitted by the WiMAX module 24 needs to be protected at this time. The detailed operation is explained as follows.

When the priority of the Bluetooth module 21 is lower than that of the WiMAX module 24 and the data received or transmitted by the WiMAX module 24 needs to be protected, the Bluetooth module 21 will be set to be disabled. In other words, if the signal BT_PRI_DATA is 0 and the signal WIMAX_COEXISTENCE_PROTECTION output by the WiMAX module 24 is 1, then the signal W_Active received by the Bluetooth module 21 is 1, and the Bluetooth module 21 does not operate.

When the priority of the Bluetooth module 21 is higher than that of the WiMAX module 24 , that is, when the signal BT_PRI_DATA is 1, the signal W_Active output by the second logic unit 23 is 0, and the Bluetooth module 21 can transmit or receive data. If the signal WIMAX_COEXISTENCE_PROTECTION output by the WiMAX module 24 is 1 at this time, the WiMAX module 24 will take a protection action on the data being received or transmitted. If the WiMAX module 24 is in the receiving mode at this time, the WiMAX module 24 can send a request (request) first, and the base station that transmits the data is requested to temporarily stop transmitting data, and when the control right is transferred to the WiMAX module 24 again, send the request again , please send the base station to continue to send data. If the WiMAX module 24 is in the transmission mode at this time, the WiMAX module 24 will suspend the transmission of data and notify the corresponding receiving device. When the control right is transferred to the WiMAX module 24 again, the untransmitted data will continue to be transmitted to the corresponding receiving device.

When the priority of the Bluetooth module 21 is higher than that of the WiMAX module 24, if the Bluetooth module 21 is in the receiving mode and the WiMAX module 24 is also operating in the receiving mode, the WiMAX module 24 can be set to receive data according to user needs. .

The first logic unit 22 mainly determines whether the power amplifier 27 in the WiMAX module 24 is enabled according to the priority of the Bluetooth module 21 , whether the Bluetooth module 21 is in the transmission mode, and whether the WiMAX module 24 is in the transmission mode. If the power amplifier 27 is not enabled, it means that the WiMAX module 24 cannot transmit data at this time. However, if the power amplifier 27 is enabled, it does not mean that the WiMAX module 24 can transmit data at this time, because the WiMAX baseband chip 25 may not be active at this time.

The first logic unit 22 first judges the operation mode of the Bluetooth module 21 and whether its priority is higher than that of the WiMAX module 24 according to the signals BT_PA_ON and BT_PRI_DATA of the Bluetooth module 21 . Then judge whether the WiMAX module 24 is in the transmission mode at this time according to the signal PA_EN_WIMAX_CONTROL of the WiMAX module 24 . If the priority of the Bluetooth module 21 is higher than that of the WiMAX module 24, the WiMAX module 24 is not allowed to be in the transmission mode. If the priority of the Bluetooth module 21 is higher than that of the WiMAX module 24, and the Bluetooth module 21 is in the receiving mode at this time, the WiMAX module 24 can be set to be in the receiving mode or not to operate. If the priority of the Bluetooth module 21 is lower than that of the WiMAX module 24 , it is necessary to determine whether the Bluetooth module 21 can operate according to the signal WIMAX_COEXISTENCE_PROTECTION output by the WiMAX module 24 .

In order to illustrate the coexistence operation mechanism between the Bluetooth module 21 and the WiMAX module 24 more clearly, please refer to FIG. 3a and FIG. 3b. 3a and 3b are schematic diagrams of an embodiment of a coexistence mode of a Bluetooth module and a WiMAX module according to the present invention. In this embodiment, the input signals include signals BT_PRI_DATA, BT_PA_ON, PA_EN_WIMAX_CONTROL and WIMAX_COEXISTENCE_PROTECTION. The output signals include W_Active and PA_EN.

In modes 9 to 16, except modes 9 and 11, the WiMAX module 24 does not work. In modes 9 and 11, although the priority of the Bluetooth module 21 is higher than that of the WiMAX module 24, both are in the receiving mode at this time, so it can be set that both can receive data at the same time.

In modes 1 to 4, the priority of the Bluetooth module 21 is lower than that of the WiMAX module 24, and the Bluetooth module 21 is in the receiving mode at this time. Whether the Bluetooth module 21 can operate at this time must first refer to whether the signal WIMAX_COEXISTENCE_PROTECTION output by the WiMAX module 24 is 1. . If the signal is 1, it means that the data received or transmitted by the WiMAX module 24 needs to be protected. Operation, such as mode 3 and 4. If the signal WIMAX_COEXISTENCE_PROTECTION output by the WiMAX module 24 is 0, the Bluetooth module 21 can be set to receive modes, such as modes 1 and 2. It should be noted that the bluetooth module 21 is set to the receiving mode at this time only means that the bluetooth module 21 can receive data, but does not mean that the bluetooth module 21 is already receiving data at this time.

In modes 5 to 8, the priority of the Bluetooth module 21 is lower than that of the WiMAX module 24. At this time, whether the Bluetooth module 21 can transmit data must refer to the signal W_ACTIVE. If the signal W_ACTIVE is 0, it means that the Bluetooth module 21 can be in the transmission mode to transmit data, such as modes 5 and 6. However, if the signal W_ACTIVE is 1, it means that the Bluetooth module 21 is set to be inoperable at this time, so the Bluetooth module 21 cannot transmit data, such as modes 7 and 8 . In addition, in mode 6, both the Bluetooth module 21 and the WiMAX module 24 can be set to the transmission mode.

It should be noted that the WiMAX module 24 and the Bluetooth module 21 cannot be set in such a way that one transmits and the other receives. This may cause the signals of the WiMAX module 24 and the Bluetooth module 21 to interfere with each other, reducing the performance of both.

FIG. 4 is a logic circuit diagram of an embodiment of the first logic unit in FIG. 2 according to the present invention. A NAND gate 41 receives the signals BT_PRI_DATA and BT_PA_ON output by the Bluetooth module 21 . Next, an AND gate 42 generates a signal PA_EN according to the output signal AND signal PA_EN_WIMAX_CONTROL of the NAND gate 41 to control whether the power amplifier 27 in the WiMAX module 24 is enabled. For the truth table of the logic circuit in FIG. 4, reference may be made to FIG. 3a and FIG. 3b.

FIG. 5 is a logic circuit diagram of an embodiment of the second logic unit in FIG. 2 according to the present invention. A NOT gate (NOT gate) 51 receives and inverts the signal BT_PRI_DATA. The AND gate 52 receives the output signal of the NOT gate 51 and the signal WIMAX_COEXISTENCE_PROTECTION output by the WiMAX module 24 to generate a signal W_ACTIVE for controlling whether the Bluetooth module 21 can transmit data. For the truth table of the logic circuit in FIG. 5, please refer to FIG. 3a and FIG. 3b.

FIG. 6 is a schematic diagram of another embodiment of an electronic device with a Bluetooth module and a wireless network module according to the present invention. The WiMAX module 64 includes a WiMAX baseband chip 65 , a WiMAX radio frequency module 66 and a power amplifier 67 . The second logic unit 63 generates a signal W_ACTIVE according to the signal BT_PRI_DATA output from the Bluetooth module 61 and the signal WIMAX_COEXISTENCE_PROTECTION output from the WiMAX module 24 to control whether the Bluetooth module 61 can transmit data at this time. The WiMAX baseband chip 65 can determine the operation mode of the WiMAX module 64 according to the signals BT_PRI_DATA and BT_PA_ON output by the Bluetooth module 61 , such as transmission mode, reception mode or no action.

When the signals BT_PRI_DATA and BT_PA_ON are both 1, it means that the priority of the Bluetooth module 61 is higher than that of the WiMAX module 64, and the Bluetooth module 61 is in the transmission mode and can transmit data, so the WiMAX baseband chip 65 sets the WiMAX module 64 to be inactive .

When the signal BT_PRI_DATA is 1 and the signal BT_PA_ON is 0, it means that the priority of the Bluetooth module 61 is higher than that of the WiMAX module 64 at this time, and the Bluetooth module 61 is in the receiving mode and can receive data. At this time, the WiMAX baseband chip 65 controls the WiMAX module 64 Inactive or in receive mode.

When the signal BT_PRI_DATA is 0, it means that the priority of the Bluetooth module 61 is lower than that of the WiMAX module 64. Whether the Bluetooth module 61 can operate depends on the signal W_ACTIVE output by the second logic unit. If the signal W_ACTIVE is 1, the Bluetooth module 61 is set to be inactive. If the signal W_ACTIVE is 0, the bluetooth module 61 can be set as a transmission mode or a reception mode.
