Detailed Description

The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification of the present application and the appended claims, the singular forms "a", "an", "the" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

The bluetooth device related in the embodiment of the present application may be a classic bluetooth device, and may also be a bluetooth device supporting classic bluetooth and bluetooth low energy. The bluetooth device may be a mobile phone, a tablet Computer, a desktop, a laptop, a notebook, an Ultra-mobile Personal Computer (UMPC), a handheld Computer, a netbook, a Personal Digital Assistant (PDA), a wearable bluetooth device, a virtual reality device, a bluetooth headset, or the like, which is not specifically limited in this embodiment. The Bluetooth devices are connected with each other through Bluetooth to form a network, wherein a connection initiator is a Master device (Master), and a receiving connector is a Slave device (Slave). All devices share the clock of the master device.

The Bluetooth related to the embodiment of the application is a wireless communication standard for short-distance data exchange, and works in a 2.4GHz unlicensed frequency band. Bluetooth may include classic Bluetooth (BR/EDR) and Bluetooth Low Energy (BLE). Classic bluetooth, which may also be referred to as conventional bluetooth or standard bluetooth. Classic bluetooth is developed and perfected on the basis of bluetooth such as the previous bluetooth specification protocol versions 1.0, 1.2, 2.0+ EDR, 2.1+ EDR, 3.0+ HS and the like, and is a general name after the low-power bluetooth appears. Bluetooth low energy, also known as Bluetooth Smart, was developed over the Wibree standard of Nokia and was introduced beginning in the Bluetooth specification protocol version 4.0. The power consumption of the low-power Bluetooth technology is 1/10 or less than that of the classic Bluetooth technology, and meanwhile, the low-power Bluetooth technology has the characteristics of short message, high coding efficiency, short connection establishment time and the like. The bluetooth technology can simultaneously transmit voice and data, and adopts circuit switching and packet switching technologies to support an asynchronous data channel, a three-way voice channel and a channel for simultaneously transmitting asynchronous data and synchronous voice. Bluetooth has two Link types including Asynchronous Connection less Link (ACL) and Synchronous Connection Oriented Link (SCO).

In recent years, more and more users use bluetooth devices to perform services such as talking, listening to music, and the like. Illustratively, fig. 1 shows a scenario of a bluetooth connection application. As shown in fig. 1, the terminal device 100 and the bluetooth headset 200 establish a bluetooth connection according to a bluetooth protocol, wherein the terminal device 100 may be a master device, the bluetooth headset 200 may be a slave device, and the terminal device 100 may transmit voice data to the bluetooth headset 200 through the bluetooth connection. In order to reduce the power consumption of bluetooth connection and prolong the service time of bluetooth devices, the bluetooth output power of existing bluetooth devices is generally low. In practical applications, the distance between the terminal device 100 and the bluetooth headset 200 and the environment may vary frequently. For example, the user puts the terminal device 100 in a living room and enters a bedroom or a balcony with the bluetooth headset 200. Since the distance between the terminal device 100 and the bluetooth headset 200 becomes large, or there is a wall or a human body block, the bluetooth signal strength may become weak. When a user listens to music or answers a call using the bluetooth headset 200, a stuck phenomenon may occur. In order to ensure the communication quality, the terminal device 100 needs to increase the bluetooth output power.

Table 1 shows the power levels and power ranges specified by the existing bluetooth protocol. According to the bluetooth protocol, different power levels have different power output ranges. For example, a bluetooth device may have a maximum output power of up to 20dBm at power class 1 and a maximum power of only 4dBm at class 3. Due to the requirement of low power consumption, most bluetooth devices have low bluetooth output power, the output power of an antenna port of the bluetooth devices does not exceed 10dBm, and even if the bluetooth devices are in a state of power level 1, the maximum output power of the bluetooth devices is far lower than the maximum output power specified by a bluetooth protocol, so that the requirement of bluetooth communication cannot be met.

TABLE 1

Grade	Maximum output power	Standard output power	Minimum output power
				1	20dBm(100mW)	Is free of	0dBm(1mW)
2	4dBm(2.5mW)	0dBm(1mW)	-6dBm(0.25mW)
				3	1dBm(0mW)	Is free of	Is free of

In the prior art, the bluetooth baseband unit in the bluetooth module can implement two modes, i.e., a high power mode and a normal power mode, so that an additional Power Amplifier (PA) can be added to the bluetooth rf path of the terminal device 100 to implement the high power design of the bluetooth module. The disadvantage of this method is that the bluetooth radio frequency channel has two power amplifiers, which respectively realize two modes of bluetooth ordinary power and high power, increase the design cost of the chip, and affect the comprehensive competitiveness of the product.

In a conventional 1X1 Single-channel WiFi, a receiving signal and a transmitting signal each occupy one antenna, i.e., a Single Input Single Output (SISO) mode. With the increase of network applications, the data volume required to be transmitted by WiFi gradually increases, and the wireless rate of 1X1 single-path WiFi is now a development bottleneck. Under the condition, two-way and multi-way WiFi technologies are developed, and a plurality of antennas are added on the basis of single-way WiFi, so that the transmission rate is higher. Nowadays, terminal devices often support multiple WiFi technologies of 2X2, 3X3, or even 4X4, and WiFi coverage is wider and transmission rate is faster. This technique may also be referred to as a Multiple Input Multiple Output (MIMO) technique. WiFi requires additional hardware circuitry including Multiple power amplifiers after using Multiple Input Multiple Output (MIMO) technology. The MIMO technology involves both spatial diversity and spatial multiplexing. By utilizing the space diversity technology, the transmitting end can transmit the same signal from different antennas, and the multiple antennas at the receiving end can verify the signals after receiving the signals, so that the larger diversity gain is obtained, the reliability of the signals is improved, and the high reliability of the connection can be ensured by using the characteristic at the position with weak signal coverage. According to the spatial multiplexing technology, a plurality of antennas at the output end transmit different signals respectively, and a plurality of antennas corresponding to the receiving end receive the signals respectively, so that the channel capacity is improved in multiples.

Based on this, the embodiments of the present application provide a method and an apparatus for adjusting bluetooth output power, which improve the bluetooth output power without increasing the cost. The basic principle is that the terminal device uses a WiFi power amplifier to realize the Bluetooth high-power mode in the Bluetooth high-power mode.

In the embodiment of the present application, the terminal device includes a bluetooth chip and a WiFi chip, and the bluetooth device may include a bluetooth chip, where the WiFi chip may operate in 2.4GHz and 5GHz frequency bands and communicate with other terminal devices through a WiFi technical protocol (e.g., IEEE 802.10A, IEEE802.11 b, IEEE802.11g, and/or IEEE802.11n, standards of the institute of electrical and electronics engineers). The WiFi chip supports a 2 × 2 Multiple Input Multiple Output (MIMO) mode and a Single Input Single Output (SISO) mode. It should be noted that, in the embodiment of the present application, the bluetooth chip may also be referred to as a bluetooth module, and the WiFi chip may also be referred to as a WiFi module.

When the Bluetooth chip or the WiFi chip sends data, the data can be sent to the radio frequency path. The radio frequency channel modulates and amplifies the data, and then converts the data into electromagnetic waves through the antenna to radiate the electromagnetic waves. The amplification processing of the transmission data is mainly completed by a power amplifier. The power amplifier can linearly amplify low-power radio frequency data to a certain power value without distortion. For convenience of description, in the embodiment of the present application, the output power of bluetooth refers to the power radiated by the antenna after bluetooth data is processed by the power amplifier.

Fig. 3A is a schematic diagram illustrating a WiFi rf path structure according to an embodiment of the present application. As shown in FIG. 3A, the WiFi chip supports 2.4GHz and 5GHz bands. The 2.4GHz rf path of the WiFi chip may include a transmit rf path and a receive rf path, where the transmit rf path may include the power amplifier 311, the low noise amplifier 351, the switch 341, and the filter. Illustratively, when the WiFi chip transmits (transmit, TX) data 321 in the 2.4GHz band, the data may be amplified by the power amplifier 311, then transmitted to the antenna 3 through the switch 341 and the duplexer 331, and radiated to the space via the antenna 3. The duplexer is used for isolating the transmitting signal and the receiving signal and ensuring normal work of both receiving and transmitting. When the WiFi chip receives data in the 2.4GHz band, the Received (RX) data 361 is received by the antenna 3, passes through the duplexer 311 and the switch 341, is amplified by the Low Noise Amplifier (LNA) 351, and is then transmitted to the WiFi chip. The transmitting rf path and the receiving rf path of the WiFi chip in the 2.4GHz band are commonly connected to the duplexer 331 through the switch 341. Similar to the 2.4GHz band, the WiFi chip may have two rf paths for transmitting data and receiving data in the 5GHz band.

It should be noted that the WiFi rf path structure shown in fig. 3A is only schematic, and the WiFi rf path may further include a plurality of electronic components. For example, in some embodiments, the transmit rf path of WiFi may also include a band pass filter and a low pass filter.

Fig. 3B shows an operation block of a terminal device in the normal power mode according to this embodiment. In some embodiments, the normal power mode may be the first power mode. For convenience of description, the operation diagram shown in fig. 3B omits the rf receiving path and some electronic components. As shown in fig. 3B, the WiFi chip of the terminal device adopts a 2X2 two-way mode, and can simultaneously transmit data through the antenna 3 and the antenna 4. In addition, the WiFi chip supports a 5GHz frequency band and a 2.4GHz frequency band and adopts a 2X2 two-way mode simultaneously. Illustratively, the WiFi chip may transmit TX data 321 and TX data 323 at the 2.4GHz band and TX data 322 at the 5GHz band at the same time. Wherein TX data 321 and TX data 322 are respectively connected to the duplexer 331 through the power amplifier 311 and the power amplifier 312, and radiated to the space via the antenna 3. Similar to the TX data 321 and the TX data 322, the TX data 323 and the TX data 324 are connected to the duplexer 332 through the power amplifier 313 and the power amplifier 314, respectively, and radiated to the space via the antenna 4. The difference is that TX data 324 is commonly connected to duplexer 332 through switch 340 with bluetooth data 325 sent by the bluetooth chip. Wherein the bluetooth data 325 is connected to the switch 340 through the power amplifier 315. The power amplifier 315 is a bluetooth power amplifier, and is configured to implement a bluetooth normal power mode. In the embodiment of the present application, in order to save power consumption, the bluetooth module is generally in a normal power mode. When a certain condition is met, for example, the distance between the master device and the slave device reaches a certain threshold, the bluetooth chip may switch from the normal power mode shown in fig. 3B to the high power mode shown in fig. 4.

Fig. 4 shows an operation block of a terminal device in a high power mode according to an embodiment of the present application. In some embodiments, the high power mode may also be the second power mode. Similar to the bluetooth normal power mode shown in fig. 3B, the WiFi chip shown in fig. 4 supports both 2.4GHz and 5GHz bands. The difference is that the bluetooth chip is connected to the switch 340 through the power amplifier 314 in the high power mode. Meanwhile, the TX data 323 and the TX data 324 commonly use the power amplifier 313. At this time, the terminal device cannot operate in the MIMO mode in the 2.4GHz and 5GHz bands at the same time. In some embodiments, the terminal device switches from MIMO mode to SISO mode in the 5GHz band. In other embodiments, the terminal device switches from the MIMO mode to the SISO mode in the 2.4GHz band. The benefit of this approach is that the bluetooth chip does not require an additional power amplifier and can also implement high power modes.

Fig. 5 is a flowchart illustrating a bluetooth high power mode switching method according to an embodiment of the present disclosure. As shown in fig. 5, the steps in the embodiment of the present application are as follows:

s501, a power control request message is received.

In order to save power consumption, the bluetooth chip of the terminal device is defaulted to operate in a normal power mode. According to the power control requirement of the bluetooth protocol, when the opposite terminal device monitors that the signal strength is weak or strong, a first message can be sent to the terminal device to request the terminal device to adjust the output power. Illustratively, the peer device sends a first message to the terminal device through a link management protocol LMP in the bluetooth protocol, where the first message is a Power-Control-Req message (Power-Control-Req) requesting the terminal device to adjust the bluetooth output Power. The opposite terminal device is a bluetooth device which establishes bluetooth connection with the terminal device, and adjusting the bluetooth output power can be to increase the bluetooth output power or to reduce the bluetooth output power. For example, as shown in fig. 6, the terminal device 100 establishes a bluetooth connection with the bluetooth headset 200, where the bluetooth headset 200 is a peer device of the terminal device 100. When the distance between the bluetooth headset 200 and the terminal device 100 becomes longer and the bluetooth headset 200 monitors that the bluetooth signal strength is lower than the preset threshold, it may send a power control request message to the terminal device 100 to request the terminal device 100 to increase the bluetooth output power. After receiving the Power Control request message, the terminal device 100 may send a Power-Control-Rsp message to the peer device. In other embodiments, the first message may be used to request the terminal device to switch to the high power mode.

Optionally, the adjusted output power may be divided into at least two levels, and each level corresponds to a specific output power value. For example, the regulated output power may be divided into a first level and a second level, where the first level corresponds to 6dBm and the second level corresponds to 8 dBm.

Alternatively, the power control request message may be used to request the terminal device 100 to increase or decrease a specific output power value. For example, the power control request message may request an increase of 6dBm or 8dBm in the bluetooth output power of the terminal device 100. The specific improved bluetooth output power value can be determined by the peer device according to the intensity of the bluetooth signal.

Optionally, the power control request message may also request the terminal device 100 to increase or decrease the bluetooth output power according to a preset rule. For example, the bluetooth output power of the terminal device may be increased or decreased by 2dBm at intervals until the bluetooth signal strength reaches a preset threshold.

Alternatively, the power control request message may request the bluetooth output power of the terminal device 100 to be increased to the maximum output power or to be decreased to the minimum power.

It should be noted that, in the embodiment of the present application, a specific manner of increasing or decreasing the bluetooth output power of the terminal device is not limited.

S502, judging whether the power control request message is a power increasing request.

After receiving a power control request sent by an opposite terminal device, a terminal device judges whether the power control request is a power increasing request. If the above power control request is a request for the terminal device to increase the output power, the terminal device executes step S503. If the power control request is not a request for the terminal device to increase power, the terminal device executes step S508 to decrease the bluetooth output power.

S503, it is determined whether the requested power to be increased is higher than a first threshold.

If the opposite terminal equipment requests the terminal equipment to increase the Bluetooth output power, the terminal equipment judges whether the power requested to be increased is higher than a first threshold value. If the requested increased power is above the first threshold, the terminal device may perform step S504 or step S504. If the requested increased power is not higher than the first threshold, the terminal device performs step S507.

In some embodiments, the first threshold is a maximum output power of the antenna port in the normal power mode of the bluetooth module. Referring to fig. 3B, when the bluetooth module of the terminal device operates in the normal power mode, the bluetooth baseband unit is connected to the duplexer through the bluetooth rf unit. The Bluetooth radio frequency unit comprises a power amplifier used for realizing a common power mode of the Bluetooth module. If the opposite terminal equipment requests for increased power, the maximum output power of the common power mode of the Bluetooth module is not exceeded, the Bluetooth mode of the terminal equipment does not need to be switched to a high power mode, and the output power requirement of Bluetooth connection can also be met. For example, assume that the bluetooth module of the terminal device is in the normal power mode, and the maximum output power of the antenna port is 10 dBm. And if the output power of the Bluetooth after the terminal equipment is improved does not exceed 10dBm, the Bluetooth module of the terminal equipment does not need to be switched to a high-power mode. The method has the advantages that under the condition of meeting the output power of the Bluetooth, the power consumption of the terminal equipment can be saved, and the transmission rate of the WiFi in the 5GHz frequency band can not be influenced.

In other embodiments, the first threshold may be a preset power value, and the preset power value may be smaller than the maximum output power of the bluetooth module in the normal power mode. The first threshold is not limited in the embodiment of the present invention.

S504, whether the Bluetooth connection supports the high power mode is judged.

This step is an optional step. The terminal equipment judges whether the Bluetooth connection established with the opposite terminal supports the high-power mode. If the bluetooth connection supports the high power mode, the terminal device performs step S505.

And S505, judging whether the high power mode switching condition is met.

If the high power mode switching condition is satisfied, the terminal device executes step S506, and the terminal device switches from the bluetooth normal power mode to the high power mode. If the high power mode switching condition is not met, the terminal equipment does not increase the existing Bluetooth output power or increases the Bluetooth output power to the maximum value of the common power mode.

Specifically, in some embodiments, WiFi traffic may be divided into two priorities, including a first priority and a second priority. Wherein the first priority traffic may be traffic with higher requirements on link rate. Such as high-quality music services, voice call services, or live services. These services need to transmit audio data, and have high requirements on transmission rate and stability. The traffic of the second priority may be traffic with lower requirements on link rate. And if the ongoing service of the WiFi module of the terminal equipment belongs to the first priority, the high-power mode switching condition is not met. And if the ongoing service of the WiFi module of the terminal equipment belongs to the second priority, the high-power mode switching condition is met. The method has the advantages that under the condition that the WiFi service and the Bluetooth service coexist, whether the high-power mode is switched can be judged according to the priority of the service, and the use experience of a user is improved. For example, as shown in fig. 4, in the embodiment of the present application, a bluetooth high power mode of the terminal device needs to use a power amplifier of a WiFi core, and at this time, a WiFi module of the terminal device cannot simultaneously use a 2 × 2 mode in two frequency bands of 5GHz and 2.4GHz, which affects a transmission rate of WiFi. If the WiFi module of the terminal device is transmitting high-quality voice data, switching the terminal device to the bluetooth high power mode may reduce the data transmission rate of WiFi, affecting the call quality of the user.

In other embodiments, the terminal device may obtain an operating parameter of the WiFi module, where the operating parameter refers to an operating parameter of the terminal device in the MIMO mode, and may include at least one of the following parameters: received signal strength, throughput rate, channel bandwidth, etc. Each parameter will be described separately below.

Received signal strength: may refer to the signal strength of the WiFi network received by the terminal device, for example, represented by a Received Signal Strength Indicator (RSSI) of the terminal device. The process of acquiring the received signal strength by the terminal device may include: the terminal equipment measures the received signal of the WiFi physical layer through the integrated WiFi chip.

Throughput rate may refer to the number of successful data transfers per unit time by the terminal device. The process of acquiring the throughput rate by the terminal device may include: counting the number of bytes transmitted and received by the terminal equipment in a period of time, and determining the number of successfully transmitted data in unit time according to the number of bytes in the period of time. There is a certain relationship between the throughput rate and the link rate of the physical layer, for example, the throughput rate is about 70% of the link rate of the physical layer. In the following example, the terminal device may also obtain a link rate of the physical layer, and use the link rate as an access parameter to replace the throughput rate for judgment.

The channel bandwidth may refer to a frequency bandwidth occupied by a signal, and for example, the channel bandwidth may be 20 megahertz (MHz), 40M, or 80M. The process of acquiring the channel bandwidth by the terminal device may include: the terminal equipment can be obtained by acquiring the working state of the WiFi physical layer.

After the terminal device obtains the working parameters, whether the high power switching condition is met can be judged according to the working parameters. Exemplarily, if the throughput rate is less than the first throughput rate threshold, the high power switching condition is satisfied; or, if the received signal strength is higher than the first received signal strength, the high power switching condition is satisfied; or, if the channel bandwidth is smaller than the first channel bandwidth threshold, the high power switching condition is satisfied.

It should be noted that, other factors may also be referred to for the high power mode switching condition, and this is not limited in this embodiment of the present application.

And S506, switching to a high-power mode.

If the terminal device satisfies the bluetooth high power switching condition, the operation mode thereof is switched from the operation mode shown in fig. 3B to the operation mode shown in fig. 4. And the working mode of the WiFi module of the terminal equipment is switched from the MIMO mode to the SISO mode. Referring to fig. 4, after switching the high power mode, the WiFi module of the terminal device cannot implement the 2x2 MIMO mode at the 2.4GHz band and the 5GHz band at the same time. The WiFi module needs to switch from MIMO mode to SISO mode. When the terminal device switches from MIMO mode to SISO mode, the switching may be performed as specified in the WiFi protocol. Specifically, the terminal device may interact with an AP providing an access service of the WiFi network through an Action frame, for example, an Action frame carries a mode switching bit (bit) bit to negotiate with the AP, so as to switch from the MIMO mode to the SISO mode; alternatively, the terminal device interacts with an AP providing an access service of the WiFi network through an Association (Re) frame, for example, an MCS rate set used by the SISO mode is set in the (Re) Association frame to switch from the MIMO mode to the SISO mode.

After the switching is completed, the terminal device may send a power control request response message to the peer device.

And S507, improving the Bluetooth transmission power.

After the terminal device increases the bluetooth transmission power, it may send a power control request response message to the peer device.

And S508, reducing the Bluetooth transmission power.

After the terminal device reduces the bluetooth transmission power, it may send a power control request response message to the peer device.

The benefit of this application embodiment is, under the unchangeable circumstances of keeping the cost, realizes bluetooth module's high power mode. Illustratively, the output power of the bluetooth module is up to 14dBm in the normal power mode, and up to 22dBm in the high power mode.
