Description

Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and more particularly, to a wireless communication device and a method for a wireless communication device. Background Art

[0002] For the convenience and flexibility of users, most current wireless communication devices are equipped with multiple transceiver radios to support different wireless technologies. For example, a wireless communication device may include a Wireless-Fidelity (Wi-Fi) transceiver radio for communicating with an Access Point (AP) (or access point, access point), and a Bluetooth (BT) transceiver radio for communicating with a headset. Such a wireless communication device can receive voice call data or digital media data from the Internet through the Wi-Fi transceiver radio, and then forward the data to the BT headset through the BT transceiver radio.

[0003] To support both Wi-Fi technology and BT technology simultaneously, a wireless communication device should include two separate transceiver radios (i.e., a Wi-Fi transceiver radio and a BT transceiver radio), and for cost reasons, some components, such as antennas and Low Noise Amplifiers (LNAs), can be shared by these transceiver radios. Specifically, in a two-stage signal amplification design for Co-Reception (Co-Rx) operation (or running), two transceivers can share an external LNA for the first-stage signal amplification, and then the second-stage LNAs in each transceiver can perform the final signal amplification and adjustment. However, this hardware design may have some drawbacks, one of which is that when the shared antenna is occupied by one transceiver radio, the other transceiver radio may not be able to perform Transmission / Reception (Tx / Rx) operations simultaneously. For example, in the case where two transceiver radios need to use the shared antenna for Rx operations, if these two transceiver radios require different LNA gain modes, only one transceiver radio is allowed to operate the LNA in the required gain mode.

[0004] Therefore, the industry desires a robust and effective way to control the shared LNA to improve the overall throughput of Co-Rx operations. Summary of the Invention

[0005] In view of this, the present invention provides a wireless communication device and a method for a wireless communication device to solve the above problems.

[0018] Detecting a plurality of second packets, wherein the second packets are all detected with strong signal indications; and

[0019] When the first packets and the second packets overlap in time, allowing a first receiver radio to successfully receive all the first packets through a low-noise amplifier shared by the first receiver radio and a second receiver radio.

[0020] The method for a wireless communication device according to the present invention includes: determining a first gain mode of a low-noise amplifier based on a first signal indication; determining a second gain mode of the low-noise amplifier based on a second signal indication, where the low-noise amplifier is shared by a first receiver radio and a second receiver radio and the low-noise amplifier is coupled to an antenna; and configuring the low-noise amplifier to operate in the first gain mode or the second gain mode based on the priorities of the first receiver radio and the second receiver radio through a packet service arbitration circuit of the wireless communication device.

[0035] Figure 1 is a block diagram of a wireless communication environment according to an embodiment of the present application.

[0036] As Figure 1 shown, the wireless communication environment 100 includes a wireless communication device 110, an AP 120, and a peer terminal 130.

[0037] The wireless communication device 110 can be a functional phone, a smart phone, a desktop computer, a laptop computer, a tablet personal computer (PC), a workstation, or any wireless communication device that supports the wireless technologies used by the AP 120 and the peer terminal 130. Specifically, the wireless communication device 110 includes at least two transceiver radios to communicate with the AP 120 and the peer terminal 130 simultaneously or separately.

[0038] The AP 120 can use a wireless technology, such as Wi-Fi technology compliant with the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, to establish a Wireless Local Area Network (WLAN) that supports two-way communication with the wireless communication device 110. Generally, the WLAN is established within a building as an extension of a wired local area network and can provide the connection for the last few meters (or more) between the wired network and the wireless communication device 110. The AP 120 typically receives, buffers, and transmits data between the established WLAN and the wired network infrastructure. The coverage range of the WLAN varies from 20 meters in areas with obstacles (such as walls, stairs, elevators, etc.) to 100 meters in areas with clear line of sight. For example, the wireless communication device 100 can receive network browsing data from the Internet and send the data to the Internet through the AP 110.

[0039] The peer terminal 130 can use another wireless technology, such as BT technology, to establish a Personal Area Network (PAN) that supports two-way communication with the wireless communication device 110. BT technology is an open wireless protocol for short-range data exchange. The peer terminal 130 can be a headset (as Figure 1 shown), a wearable device (e.g., a smartwatch), or a peripheral device (e.g., a keyboard, a mouse, a microphone, or a sensor).

[0040] According to a novel aspect, the transceivers in the wireless communication device 110 share the same antenna and external LNA, and the wireless communication device 110 further includes a Packet Traffic Arbitration (PTA) circuit. The PTA circuit collects Rx request information (including the required gain mode of the shared LNA) from the transceivers and determines, for each packet, which transceiver can access (or access to) the shared LNA with the required gain mode for Rx operation.

[0041] Figure 2 is a block diagram showing a wireless communication device according to an embodiment of the present application.

[0042] As Figure 2 shown, a wireless communication device (e.g., the wireless communication device 110) can include an antenna 10, an LNA 20, two transceivers 30 and 40, a baseband processing device 50, a PTA circuit 60, a controller 70, a storage device or equipment 80, and an Input / Output (I / O) device 90.

[0043] The LNA 20 (or the first-stage LNA) can perform first-stage signal amplification on the radio frequency (RF) wireless signal received from the antenna 10 and transmit the processed RF wireless signal to the transceiver radio 30 and / or the transceiver radio 40. Specifically, the LNA 20 can operate in a high-gain mode or a low-gain mode according to the indication of the PTA circuit 60 to perform first-stage signal amplification. When operating (running or working) in the high-gain mode, the LNA 20 can provide high power gain for low-power signals (e.g., signals with RSSI = -98 to -50 dBm). When operating (running or working) in the low-gain mode, the LNA 20 can provide low power gain for high-power signals (e.g., signals with RSSI = -50 to -6 dBm). Therefore, in this embodiment, the circuit 60 can control the gain level (e.g., high power gain or low power gain) of the LNA 20 according to the RSSI magnitude. In this embodiment, the current RSSI can be used to predict whether high power gain (high gain) or low power gain (low gain) should be used for the RSSI in the next second.

[0044] Each of the transceiver radio devices (transceiver radios) 30 and 40 (which can be respectively referred to as the first transceiver radio and the second transceiver radio) can receive the processed RF wireless signal from the LNA 20 and convert the signal into a baseband signal that is subsequently processed by the baseband processing device 50, or receive the baseband signal from the baseband processing device 50 and convert the baseband signal into an RF wireless signal, which is then transmitted through the antenna 10. Each of the transceiver radios 30 and 40 can include multiple hardware devices to perform radio frequency conversion during Rx (receive) and / or Tx (transmit or send) operations. That is, each of the transceiver radios 30 and 40 can be understood as a hybrid component of Rx and Tx radio modules. For example, each of the transceiver radios 30 and 40 can include its own LNA (or the second-stage LNA) to perform final signal amplification and adjustment, and a mixer for multiplying the baseband signal by a carrier oscillating in the radio frequency of the supported wireless technology. The radio frequency can be 2.4 GHz used in Wi-Fi technology and BT technology, or it can be 5 GHz used in Wi-Fi technology, or other radio frequencies, depending on the wireless technology used.

[0045] Specifically, each of the transceiver radio devices 30 and 40 can detect data packets (e.g., Wi-Fi packets or BT packets) based on the received RF wireless signals, and determine the signal indicator (or signal indicator) of the data packet (e.g., Received Signal Strength Indicator (RSSI), Signal-to-Noise Ratio (SNR), or Packet Error Rate (PER), etc.). Thereafter, the transceiver radios 30 and 40 can each determine the desired gain mode of the LNA (i.e., the gain mode in which the transceiver radio 30 / 40 wishes to operate the LNA), and send an Rx request including the desired gain mode to the PTA circuit 60. For example, if the RSSI of the detected Wi-Fi data packet is very weak (e.g., -85 dBm), the desired gain mode may be the high gain mode; or if the RSSI of the detected BT data packet is very strong (e.g., -25 dBm), the required gain mode may be the low gain mode.

[0046] The baseband processing device 50 can perform baseband signal processing, including Analog-to-Digital Conversion (ADC) / Digital-to-Analog Conversion (DAC), gain adjustment, modulation / demodulation, encoding / decoding, etc. The baseband processing device 50 can include multiple hardware components to perform baseband signal processing. For example, the baseband processing device 50 can include a digital processor (or referred to as a baseband processor).

[0047] The PTA circuit 60 can receive Rx request information from the transceiver radios 30 and 40, including the desired gain mode of the LNA 20 (e.g., high gain mode or low gain mode), and determine, for each data packet, which transceiver radio can access (or access) the LNA 20 in the required gain mode for Rx operation.

[0048] The controller 70 can be a general-purpose processor, a Micro Control Unit (MCU), an application processor, a Digital Signal Processor (DSP), a Graphics Processing Unit (GPU), a Holographic Processing Unit (HPU), a Neural Processing Unit (NPU), etc., which includes various circuits for providing data processing and computing functions, and controls the transceiver radio and a baseband processing device 50 for wireless communication with the AP 120 and the peer terminal 130, storing data to and retrieving data from a storage device (or apparatus) 80, and receiving user input or output signals through the I / O device 90.

[0049] As those of ordinary skill in the art will understand, the circuitry of the controller 70 will typically include transistors that are configured to control the operation of the circuitry according to the functions and operations described herein. As will be further understood, the specific structure or interconnection of the transistors is typically determined by a compiler, such as a Register Transfer Language (RTL) compiler. The RTL compiler can be operated by a processor according to a script that is very similar to an assembly language code to compile the script into a form for the layout or fabrication of the final circuitry. In fact, RTL is well-known for its role and use in facilitating the electronic and digital system design process.

[0050] The storage device 80 can be a non-transitory machine-readable storage medium, including memory, such as FLASH memory or Non-Volatile Random Access Memory (NVRAM), or a magnetic storage device, such as a disk or tape, or an optical disk, or any combination thereof, that is applied to store program codes of data, instructions, and / or applications, an operating system (OS), and / or communication protocols.

[0051] The I / O device 90 can include one or more buttons, a keyboard, a mouse, a touchpad, a camera, a microphone, and / or a speaker, etc., to serve as a Man-Machine Interface (MMI) for interacting with the user.

[0052] It should be understood that Figure 2The components described in the embodiments are for illustrative purposes only and are not intended to limit the scope of the present application. For example, a wireless communication device may include more components, such as a display device and / or additional baseband processing devices. The display device may include a liquid-crystal display (LCD), a light-emitting diode (LED) display, an organic LED (OLED) display, an electronic paper display (EPD), etc. to provide a display function. The additional baseband processing device may provide baseband signal processing functions only for one of the radio transceivers 30 - 40, while the baseband processing device 50 may provide baseband signal processing functions only for the other one of the radio transceivers 30 - 40.

[0053] Figure 3 FIG. is a schematic diagram illustrating the Co-Rx operation (or work, job) of multiple transceiver radios according to an embodiment of the present application. The present invention determines the gain mode required for the receiver radio with a higher matching priority according to the priority of the receiver radio. Therefore, for important packets, their priority is increased to ensure a higher transmission success rate. Thus, the embodiments of the present invention substantially increase the transmission efficiency, reduce the probability of disconnection, improve the transmission stability, and substantially and effectively increase the overall throughput or transmission volume of the Co-Rx operation due to the reduced probability of disconnection.

[0054] At time t1, the first radio transceiver (e.g., a Wi-Fi radio transceiver) detects a data packet (e.g., a Wi-Fi packet including a preamble, a signal-field (SIG), and a payload). In response to the detected data packet, the first transceiver radio determines the signal indicator (e.g., RSSI) of the packet (data packet) and the desired gain mode of the LNA based on the signal indicator (or signal indication).

[0055] At time t2, the first transceiver radio sends an Rx request with the desired gain mode to the PTA circuit. In one example, the Rx request may include a "WF_Rx_Req" parameter and a "WF_DES_GainMode" parameter, where the "WF_Rx_Req" parameter indicates that the Wi-Fi transceiver radio requests an Rx operation, and the "WF_DES_GainMode" parameter indicates the desired gain mode of the LNA. In another example, the "WF_Rx_Req" parameter and the "WF_DES_GainMode" parameter may be sent to the PTA circuit separately in different signals.

[0056] At time t3, the PTA circuit grants the Rx request from the first transceiver radio because the LNA is now not occupied by any transceiver radio. In response to granting the Rx request, the PTA circuit configures the LNA to operate in the required gain mode indicated in the Rx request from the first transceiver radio, and then replies to the first transceiver radio with a grant signal indicating that the Rx request is granted (or approved).

[0057] Once the first transceiver radio receives the approval signal (grant signal), it can access (or retrieve) the LNA to receive packets until time t4.

[0058] At time t4, the second radio transceiver (e.g., BT radio transceiver) detects a data packet (e.g., a BT packet including a preamble, a signal field (SIG), and a payload). In response to the detected data packet, the second transceiver radio determines the signal indicator (e.g., RSSI) of the packet and the desired gain mode of the LNA according to the signal indication.

[0059] At time t5, the second transceiver radio sends an Rx request with the desired gain mode to the PTA circuit. In one example, the Rx request may include a "BT_Rx_Req" parameter and a "BT_DES_GainMode" parameter, where the "BT_Rx_Req" parameter indicates that the BT transceiver radio requests an Rx operation, and the "BT_DES_GainMode" parameter indicates the desired gain mode of the low-noise amplifier. In another example, the "BT_Rx_Req" parameter and the "BT_DES_GainMode" parameter may be sent to the PTA circuit separately in different signals.

[0060] At time t6, the PTA circuit determines whether to grant (or approve) the Rx request from the second transceiver radio based on the priorities (or priorities) of the two transceiver radios. The priorities of the two transceiver radios may be predetermined or provided by the transceiver radios, e.g., through the Rx request. In response to the determination result, the PTA circuit may or may not need to configure the LNA to switch to another gain mode, and then reply to the second transceiver radio with a grant / deny signal indicating that the Rx request is granted or denied. In this embodiment, the priorities may be controlled or set manually, e.g., preset after power-on, or set subsequently through detecting scenarios or control instructions.

[0061] In one example, if WF_DES_GainMode is different from BT_DES_GainMode and the priority of the second transceiver radio is higher than that of the first transceiver radio, the PTA circuit needs to configure the LNA to switch to the desired gain mode indicated by BT_DES_GainMode and reply to the second transceiver radio with an approval signal. Once the second transceiver radio receives the approval signal, it can access the LNA to receive data packets until the next data packet detection occurs in the first transceiver radio. Meanwhile, the PTA circuit may need to send a rejection signal to the first transceiver radio to invalidate the previously issued approval, causing the first transceiver radio to yield access to the LNA for the second transceiver radio.

[0062] In another example, if WF_DES_GainMode is the same as BT_DES_GainMode, the PTA circuit does not need to configure the LNA to switch the gain mode (i.e., remain in the current gain mode) and reply to the second transceiver radio with an approval signal.

[0063] In yet another example, if WF_DES_GainMode is different from BT_DES_GainMode and the priority of the first transceiver radio is higher than or equal to that of the second transceiver radio, the PTA circuit does not need to configure the LNA to switch the gain mode (i.e., remain in the current gain mode) and reply to the second transceiver radio with a rejection signal.

[0064] At time t7, if the Rx request of the second transceiver radio was not granted at time t6, the first transceiver radio can send an Rx complete signal to the PTA circuit.

[0065] At time t8, if an Rx complete signal is received from the first transceiver radio, the PTA circuit can configure the LNA to switch to the desired gain mode indicated by BT_DES_GainMode and send an approval signal to the second transceiver radio.

[0066] At time t9, if the Rx request of the second transceiver radio was granted at time t6 or t8, the second transceiver radio can send an Rx complete signal to the PTA circuit.

[0067] Figure 4 is a schematic diagram showing packet-by-packet (or per-packet) LNA control for Co-Rx operation according to an embodiment of the present application.

[0068] In this embodiment, it is assumed that the priority of the Wi-Fi transceiver radio is higher than that of the BT transceiver radio, and this is used as an example for illustrative purposes.

[0069] like Figure 4 As shown, the gain mode of the shared (or shared) LNA is configured to favor the desired gain mode requested by the Wi-Fi transceiver radio. Therefore, in each arbitration of the Co-Rx operation, the Wi-Fi transceiver always wins, that is, all Rx operations of the Wi-Fi transceiver are successful. On the other hand, if the BT transceiver radio and the Wi-Fi transceiver radio both request the same gain mode of the shared LNA, or if the Wi-Fi transceiver radio is idle, the Rx operation of the BT transceiver radio is mostly (mostly) successful. Otherwise, if the BT transceiver radio and the Wi-Fi transceiver radio request different gain modes of the shared LNA, the Rx operation of the BT transceiver radio will fail (indicated by the dotted box).

[0070] Figure 5 is a schematic diagram illustrating cycle-based LNA control for Co-Rx operation according to conventional practice.

[0071] like Figure 5 As shown, the gain mode of the shared LNA is configured to repeatedly switch between the high gain mode and the low gain mode in a cycle-based manner. When the shared LNA operates in the high gain mode, only the Rx operations of the shared LAN that require the high gain mode can be successfully performed in the Wi-Fi transceiver radio and the BT transceiver radio. Figure 5 In the scenario, the RSSI of Wi-Fi packets remains high (remains high), while the RSSI of BT packets changes frequently. Therefore, during the period when the shared LAN is operating in high-gain mode, the Rx operations of the Wi-Fi transceiver radio are all successful because the desired gain mode is the same as the current gain mode of the shared LNA. On the other hand, most of the Rx operations of the BT transceiver radio fail because the desired gain mode is mostly different from the current gain mode of the shared LNA.

[0072] It should be understood that Figure 5 Compared with the traditional practice (or approach), the present application Figure 4Embodiments can achieve a better success rate for Co-Rx operations. In the traditional method, the shared LAN repeatedly switches between high-gain and low-gain modes. In this way, there will be cases of reception failure in both the Rx operation of the Wi-Fi transceiver radio and the Rx operation of the BT transceiver radio, and thus the success rates of the Rx operations of the Wi-Fi and BT transceiver radios cannot be guaranteed. For example, the success rate of the Rx operation of the Wi-Fi transceiver radio is 80%, and the success rate of the Rx operation of the BT transceiver radio is 80%. Therefore, failures will occur in both the Wi-Fi and BT Rx operations, affecting the use. In the embodiments of the present invention, a priority method is adopted, so that the failure will only occur on one side (for example, if the Wi-Fi priority is higher than that of BT, then only BT will fail). In the embodiments of the present invention, the transceiver radio set to a high priority will still encounter a gear that is not suitable for itself (high gain or low gain). Therefore, the embodiments of the present invention help to classify or categorize the transceiver radios. Assuming that the BT priority is preset to be high, then the success rate of the Rx operation of the Wi-Fi transceiver radio is 60%, while the success rate of the Rx operation of the BT transceiver radio is 100%. Although it seems that the overall success rate remains unchanged, the embodiments of the present invention can ensure a higher transmission success rate by increasing the priority of important packets (packets with a higher importance level), and reducing the priority of less important packets (packets with a lower importance level). The possibility of failure only occurs on less important packets (packets with a lower importance level). Therefore, the embodiments of the present invention substantially increase the transmission efficiency, reduce the probability of disconnection, and improve the stability of transmission. In the embodiments of the present invention, the priorities of the Wi-Fi transceiver radio and the BT transceiver radio can be set manually (for example, determining which priority is higher according to the importance of the packets), or the priority of the packet type with a higher importance level can be set higher, or the above two can be combined. For example, the priority of the Wi-Fi transceiver radio is set higher, and the priority of some of the packet types therein is set higher; these settings or configurations can be freely designed according to requirements, and the present invention does not make specific limitations.

[0073] Figure 6 is a schematic diagram showing the Co-Rx operation of multiple transceiver radios according to another embodiment of the present application.

[0074] It should be understood that Figure 6 the embodiments of Figure 3 are similar to the embodiments of Figure 3 except that the embodiments of Figure 6 span a shorter time period, while the embodiments of

[0075] In this embodiment, it is assumed that the priority of the Wi-Fi transceiver radio is higher than that of the BT transceiver radio. In terms of the traffic pattern, Wi-Fi packets are detected in an alternating sequence of strong RSSI and weak RSSI, while BT packets are all detected with strong RSSI. In this embodiment, it is assumed that the priority of the Wi-Fi transceiver radio is higher than that of the BT transceiver radio. Therefore, Wi-Fi dominates the LNA gain setting (high gain or low gain) due to its high priority. When Wi-Fi receives strong RSSI, it will use LG (low gain mode), and when Wi-Fi receives weak RSSI, it will use HG (high gain mode). Figure 6 In the embodiment of, the timing of the gain setting (high gain or low gain) to be switched by Wi-Fi is sequenced, so Figure 6 In the embodiment of, it is shown that HG / LG (high gain / low gain) alternates. The reason for this alternation is that Wi-Fi continuously receives strong and weak RSSI. Since the priority of the Wi-Fi transceiver radio is higher than that of the BT transceiver radio, BT can only transmit following the LNA gain setting (high gain or low gain) of the Wi-Fi transceiver radio.

[0076] Specifically, the Wi-Fi transceiver radio can be connected to an AP configured to send Wi-Fi data packets. Among them, Wi-Fi data packets with sequence numbers (Sequence Number, SN) = 1, 3, 5 are sent at a high power level (i.e., the Wi-Fi transceiver radio may detect such Wi-Fi data packets with strong RSSI), and Wi-Fi data packets with SN = 2, 4, 6 are sent at a low power level (i.e., the Wi-Fi transceiver radio may detect such Wi-Fi data packets with weak RSSI). Figure 6 The embodiment of is only one possible implementation. There may be other implementation methods in specific implementations, such as high gain and low gain occurring in a random manner, and so on. Figure 6 This is only for illustration and understanding, and is not a limitation of the present invention.

[0077] The BT transceiver radio can be configured to continuously send BT scan packets to discover any peer terminals, and the peer terminals can be configured to reply to the BT transceiver radio with BT scan response data packets at a high power level (i.e., the BT transceiver radio can detect such BT scan response data packets with strong RSSI).

[0078] Such as Figure 6As shown, since the Wi-Fi data packet and the BT scan response data packet overlap in time, arbitration on which transceiver radio should access (or access) the shared LAN is performed on a per-data packet (or per-packet) basis (or based on each packet). Since the priority of the Wi-Fi transceiver radio is higher than that of the BT transceiver radio, the Wi-Fi transceiver radio always wins the arbitration. That is, the shared LAN is configured to operate in any gain mode required by the Wi-Fi transceiver radio to allow the Wi-Fi transceiver radio to successfully receive all Wi-Fi data packets. In this embodiment, different priorities are set for different packet types. For example, when a packet type is detected as an important packet (or a special packet, or a designated packet, etc.), the shared LAN can be instructed to preferentially receive the important packet, where the important packet, or the special packet, or the designated packet, etc. can be freely set as needed, or the reception priority of some types of packets is set higher (important packets). Therefore, in the embodiment of the present invention, the configuration of the shared LAN can be enabled based on the packet type (for example, operating in a high-gain or low-gain mode, or in any gain mode required by the Wi-Fi transceiver radio or the BT transceiver radio). That is, in the prior art, the shared LAN repeatedly switches between the high-gain mode and the low-gain mode based on the time sequence. In the embodiment of the present invention, the shared LAN is set to switch between the high-gain mode and the low-gain mode based on each packet. For example, if the priority of the Wi-Fi transceiver radio is set higher than that of the BT transceiver radio, then when a packet from the Wi-Fi transceiver radio is received, the shared LAN will switch to the gain mode suitable for the current Wi-Fi transceiver radio (high-gain mode or low-gain mode); for example, if the priority of the BT transceiver radio is set higher than that of the Wi-Fi transceiver radio, then when a packet from the BT transceiver radio is received, the shared LAN will switch to the gain mode suitable for the current BT transceiver radio (high-gain mode or low-gain mode).

[0079] Figure 7 FIG. is a flowchart of a method for Co-Rx operation of multiple transceiver radios sharing the same antenna and LNA according to an embodiment of the present application.

[0080] In step S710, a first receiver radio of a wireless communication device determines a first gain mode of the LNA based on a first signal indicator (signal indication). In one example, the first receiver radio can be a Wi-Fi receiver radio, and the first signal indicator (signal indication) can include the RSSI, SNR, or PER of a Wi-Fi packet detected by the first receiver radio.

[0081] In step S720, the second receiver radio of the wireless communication device determines a second gain mode of the LNA based on the second signal indication, where the LNA is shared by the first receiver radio and the second receiver radio and is coupled to the antenna. In one example, the second receiver radio may be a BT receiver radio, and the second signal indicator may be the RSSI, SNR, or PER of the BT data packet detected by the second receiver radio.

[0082] In step S730, the PTA circuit of the wireless communication device configures the LNA to operate in the first gain mode or the second gain mode based on the priorities of the first receiver radio and the second receiver radio. In one example, the PTA circuit may configure the LNA to switch to the first gain mode in response to the priority of the first receiver radio being higher than the priority of the second receiver radio. In another example, the PTA circuit may configure the LNA to switch to the second gain mode in response to the priority of the second receiver radio being higher than the priority of the first receiver radio. In yet another example, in response to the priority of the first receiver radio being equal to the priority of the second receiver radio, the PTA circuit may configure the LNA to remain in its current gain mode, whether it is the first gain mode or the second gain mode.

[0083] Based on the configured gain mode of the LNA, in response to the LNA being configured to operate in the first gain mode, the PTA circuit may permit only the first receiver radio to access (or access to) the LNA in response to the LNA being configured to operate in the first gain mode, or in response to the LNA being configured to operate in the second gain mode, permit only the second receiver radio to access (or access to) the LNA.

[0084] Figure 8 FIG. is a flowchart of a method for Co-Rx operation of multiple transceiver radios sharing the same antenna and LNA according to another embodiment of the present application.

[0085] In step S810, the first receiver radio of the wireless communication device detects a plurality of first packets (first data packets), where the first packets with strong signal indicators (strong signal indications) and weak signal indicators (weak signal indications) are detected in an alternating order. In one example, the first receiver radio may be a Wi-Fi receiver radio, and the first packets may include Wi-Fi data packets with SN = 1, 3, 5 detected with strong RSSI and Wi-Fi data packets with SN = 2, 4, 6 detected with weak RSSI.

[0086] In step S820, a second receiver radio of the wireless communication device detects a plurality of second packets (second data packets), where the second packets are all detected with a strong signal indicator. In one example, the second receiver radio may be a BT receiver radio, and the second packets may be BT scan response packets detected with a strong RSSI.

[0087] In step S830, when the first packet and the second packet overlap in time, the first receiver radio is allowed to successfully receive all the first packets through an LNA (shared LNA) shared by the first receiver radio and the second receiver radio. Specifically, the LNA is configured to operate in a low-gain mode to receive the first packets with a strong signal indication, and operate in a high-gain mode to receive the first packets with a weak signal indication.

[0088] Those skilled in the art will readily observe that many modifications and changes can be made to the device and method while maintaining the teachings of the present invention. Therefore, the above disclosure should be construed as being limited only by the bounds and scope of the appended claims.
