Please refer to FIG. 2 , which is a structural block diagram of an electronic device provided by an embodiment of the present disclosure. The electronic device 200 may include a transceiver chip 210 and a plurality of radio frequency signal transmission channels (not shown in FIG. 2). Among them, the transceiver chip 210 may include a digital radio frequency unit 211 and a digital-to-analog converter DAC 212. Each radio frequency signal transmission channel (not shown in FIG. 2 ) may include a first filter 221 , a first mixer 222 , a power amplifier PA 223 , an antenna 224 and an envelope tracking ET power supply module 225 . In FIG. 2 , the number of multiple radio frequency signal transmission channels (not shown in FIG. 2 ) is N as an example, and N is an integer greater than 1. As an example, some devices in the radio frequency signal transmission channel may be integrated on the transceiver chip 210 . In addition, TX ₀ _L0 in Figure 2 is the local oscillator signal of the radio frequency. That is, the L0 intermediate frequency signal is mixed with the local oscillator frequency of the radio frequency through mixing, which also plays a role in frequency locking.

Among them, the digital radio frequency unit 211 sends the digital signal of the original uplink data to the digital-to-analog converter DAC 212. The digital-to-analog converter DAC 212 converts the digital signal into an analog signal, outputs N analog signals, and sends them to the N first filters 221 respectively. The analog signal of each channel passes through the first filter to filter out interference such as out-of-band clutter. The filtered N analog signals are mixed by the first mixer and divided into N independent radio frequency transmission signals. From this, the data to be sent by the electronic device is processed by the transceiver chip and multiple radio frequency signal transmission channels to generate N an independent data stream. In one implementation, the maximum bandwidth supported by each radio frequency signal transmission channel is 100 MHz. In this way, the filtered N analog signals are mixed by the first mixer and divided into independent N channels of 100 MHz. The radio frequency transmits the signal, and the data to be sent by the electronic device is processed by the transceiver chip and multiple radio frequency signal transmission channels to generate N independent data streams of 100 megabytes.

When each independent data stream passes through the power amplifier 223, if the opening conditions of the ET function of the radio frequency signal transmission channel are met, the envelope tracking function of the radio frequency signal transmission channel is turned on, and normal signal amplification processing is performed, so that the data passes through the third Three filters 2 and antenna transmit.

Please refer to FIG. 3 , which is a structural block diagram of another electronic device provided by an embodiment of the present disclosure. The electronic device 300 may include a transceiver chip 310 and a plurality of radio frequency signal transmission channels (not shown in FIG. 3). Among them, the transceiver chip 310 may include a digital radio frequency unit 311, a digital-to-analog converter DAC 312 and a second filter 313. Each radio frequency signal transmission channel (not shown in FIG. 3 ) may include a second mixer 321 , a power amplifier PA 322 , an antenna 323 and an envelope tracking ET power supply module 324 . In FIG. 3 , the number of multiple radio frequency signal transmission channels (not shown in FIG. 3 ) is N as an example, and N is an integer greater than 1. As an example, some devices in the radio frequency signal transmission channel may be integrated on the transceiver chip 310 . In addition, TX ₀ _L0 in Figure 3 is the local oscillator signal of the radio frequency. That is, the L0 intermediate frequency signal is mixed with the local oscillator frequency of the radio frequency through frequency mixing, which also plays a role in frequency locking.

Among them, the digital radio frequency unit 311 sends the digital signal of the original uplink data packet to the digital-to-analog converter DAC 312. Digital-to-analog converter DAC 312 converts digital signals into analog signals. The second filter 313 filters the analog signal to output a filtered signal. The processor divides the filtered signal into at least two filtered signals according to the uplink resources and the maximum bandwidth supported by each radio frequency signal transmission channel, and sends each filtered signal to the corresponding second mixer to obtain the filtered signal of each channel. The radio frequency corresponding to the signal transmits the signal to encapsulate the original uplink data packet into at least two sub-data packets; the processor transmits the at least two sub-data packets through the corresponding power amplifier and antenna. That is to say, the analog signal outputs N filtered signals through the second filter 313 and forwards them to N second mixers 321 respectively to filter out interference such as out-of-band clutter. After the signal is mixed by the second mixer 321, it is divided into N independent radio frequency transmission signals. The data to be sent by the electronic device is processed by the transceiver chip and multiple radio frequency signal transmission channels to generate N independent data streams. In one implementation, the maximum bandwidth supported by each RF signal transmission channel is 100 MHz. In this way, after the signal is mixed by the second mixer 321, it is divided into independent N channels of 100 MHz RF transmission signals. Thus, The data to be sent by the electronic device is processed by the transceiver chip and multiple radio frequency signal transmission channels to generate N independent data streams of 100 megabytes.

When each independent data stream passes through the power amplifier PA 322, if the opening conditions of the ET function of the radio frequency signal transmission channel are met, the envelope tracking function of the radio frequency signal transmission channel is turned on, and normal signal amplification processing is performed so that the data passes through The fourth filter 3 and antenna 323 transmit.

It should be noted that ET technology is a power supply technology that can improve the energy efficiency of radio frequency power amplifiers; the principle of ET technology is to make the power amplifier of the radio frequency signal transmission channel operate in the compression zone as much as possible, so that the power supply voltage of the power amplifier changes with the input The envelope changes of the signal; ET technology tracks each power level in the envelope and calculates the most appropriate voltage for each power point in the envelope. The high power point provides a relatively high voltage, and the low power point provides a relatively high voltage. A relatively low voltage is provided at the power point, so that each power point has an optimal voltage to reduce the energy of the voltage and thereby save power. In the embodiment of the present disclosure, each ET power module can process uplink data signals with a bandwidth of 100 MHz.

It should also be noted that in some embodiments of the present disclosure, the number of multiple radio frequency signal transmission channels is related to the maximum bandwidth supported by the network device and the maximum bandwidth supported by each radio frequency signal transmission channel. For example, assuming that the maximum bandwidth supported by network equipment is 400 MHz and the maximum bandwidth supported by each RF signal transmission channel is 100 MHz, the number of multiple RF signal transmission channels is four, that is, The electronic device contains four radio frequency signal transmission channels. For another example, taking the maximum bandwidth supported by network equipment as 800 MHz and the maximum bandwidth supported by each radio frequency signal transmission channel as 100 MHz, the number of multiple radio frequency signal transmission channels is eight, that is to say , the electronic device contains eight radio frequency signal transmission channels. For another example, assuming that the maximum bandwidth supported by network equipment is 1200 MHz and the maximum bandwidth supported by each radio frequency signal transmission channel is 100 MHz, the number of multiple radio frequency signal transmission channels is twelve, that is Said, electronic equipment contains twelve radio frequency signal transmission channels.

The process of uplink data transmission will be described below based on the hardware structure of the above-mentioned electronic device. Please refer to FIG. 4 , which is a flow chart of an uplink data transmission method for an electronic device according to an embodiment of the present disclosure. For the structure of the electronic device, reference may be made to the structural description of the electronic device shown in FIG. 2 or FIG. 3 , and will not be described again here. As shown in Figure 4, the uplink data transmission method of the electronic device may include but is not limited to the following steps.

In step 401, the uplink resources allocated by the network device to the electronic device are determined.

It should be noted that when an electronic device sends uplink data, it first needs to request the network device to allocate uplink resources to the electronic device, so that the electronic device can transmit uplink data on the uplink resources allocated by the network device.

In one implementation, a cache status report BSR is sent to the network device; the BSR is used to notify the network device of the size of the uplink resources that need to be allocated to the electronic device; receives resource configuration information sent by the network device; the resource configuration information is used by the network device to provide the electronic device with The device configures uplink resources; based on the resource configuration information, determines the upload resources allocated by the network device to the electronic device.

That is to say, the electronic device can send a buffer status report BSR to the network device, so that the network device knows how much data exists in the upstream buffer of the electronic device and needs to be sent. The network device receives the cache status report BSR sent by the electronic device, and can allocate uplink resources to the electronic device based on the cache status report BSR. For example, 1000 data resource blocks RB are configured. When the electronic device receives the resource configuration information sent by the network device (the resource configuration information is used to indicate the location and size of the resource, etc.), the electronic device can determine the upload resources allocated by the network device to the electronic device based on the resource configuration information, so that the electronic device can Transfer upload data on the upload resource.

In step 402, the maximum bandwidth supported by each radio frequency signal transmission channel is determined.

In the embodiment of the present disclosure, the maximum bandwidth supported by each radio frequency signal transmission channel is consistent with the ET function of the envelope tracking ET power supply module in each radio frequency signal transmission channel. For example, the ET function of the envelope tracking ET power supply module can For the processing of uplink data signals with a bandwidth of 40MHz to 60MHz, the maximum bandwidth supported by the RF signal transmission channel can be 40MHz to 60MHz; for another example, the ET function of the envelope tracking ET power module can process uplink data signals with a bandwidth of 100MHz. , then the maximum bandwidth supported by the radio frequency signal transmission channel can be 100MHz. In one implementation, the maximum bandwidth supported by each radio frequency signal transmission channel may be 100 MHz.

In step 403, the original uplink data packet is encapsulated into at least two sub-data packets according to the uplink resources and the maximum bandwidth supported by each radio frequency signal transmission channel.

It should be noted that uplink resources are allocated by network equipment and are related to the BSR request of electronic equipment, the size of available network resources and network quality. Network equipment does not know how electronic equipment transmits, and network equipment allocates them directly. When uplink resources are obtained, the corresponding data resource blocks RB will be allocated to the home radio frequency signal transmission channel during resource mapping.

In a possible implementation, at least two target radio frequency signal transmission channels where the uplink resources fall on multiple radio frequency signal transmission channels can be determined based on the uplink resources and the maximum bandwidth supported by each radio frequency signal transmission channel; based on the uplink The resource size falls on each target radio frequency signal transmission channel, and the original uplink data packet is encapsulated into sub-data packets corresponding to the resource size on each target radio frequency signal transmission channel.

For example, as shown in Figure 5, take the network device allocating 1,000 RBs to an electronic device. Assume that the electronic device contains N radio frequency signal transmission channels. According to the uplink resources and the maximum supported by each radio frequency signal transmission channel, Bandwidth, determine that the uplink resources fall on some radio frequency signal transmission channels, such as the first radio frequency signal transmission channel and the second radio frequency signal transmission channel. Among them, the resource size on the first radio frequency signal transmission channel is 550 RBs, and the resource size on the first radio frequency signal transmission channel is 550 RBs. The resource size on the two radio frequency signal transmission channels is 450 RB, then the original uplink data packet is encapsulated into sub-data packets corresponding to the resource size on the first radio frequency signal transmission channel and the sub-data packets corresponding to the resource size on the second radio frequency signal transmission channel. The sub-data packet corresponding to the resource size is encapsulated into two sub-data packets.

In step 404, at least two sub-data packets are transmitted through corresponding radio frequency signal transmission channels.

In embodiments of the present disclosure, in a sidelink (also known as through-link) communication system, the electronic device may transmit at least two sub-data packets to other terminal devices through corresponding radio frequency signal transmission channels. In the 5G new radio (NR) system, the electronic device can transmit at least two sub-data packets to the network device through the corresponding radio frequency signal transmission channel.

In some embodiments of the present disclosure, the total transmission power of the electronic device is determined; according to the total transmission power, the transmission power of the target radio frequency signal transmission channel for transmitting the sub-data packet is determined; based on envelope tracking in the target radio frequency signal transmission channel The ET power module performs envelope tracking processing on the transmission power of the target RF signal transmission channel. That is to say, the total transmission power of the electronic device can be determined, and based on the power allocation protocol, the total transmission power can be determined according to the transmission power of each target radio frequency signal transmission channel used to transmit sub-data packets, and for each target radio frequency signal The transmit power of the transmit channel undergoes envelope tracking ET processing.

For example, taking the target radio frequency signal transmission channel as the first radio frequency signal transmission channel and the second radio frequency signal transmission channel, assuming that the total transmission power of the electronic device is determined to be Tx Power, then according to the RB of the first radio frequency signal transmission channel The total transmission power is allocated by the number of RBs and the number of RBs of the second radio frequency signal transmission channel as Tx Power. Taking the total number of RBs allocated by network equipment to electronic devices as an example, the number of RBs in the first radio frequency signal transmission channel is 550, then the transmission power of the first radio frequency signal transmission channel is Tx Power*(550/1000 ), the number of RBs in the second radio frequency signal transmission channel is 450, then the transmission power of the second radio frequency signal transmission channel is Tx Power*(450/1000). When each sub-data packet passes through the power amplifier, if the transmission power of the radio frequency signal transmission channel is greater than a certain threshold, that is, the current scene is a high transmission power scene, the ET function of the radio frequency signal transmission channel is turned on to control the radio frequency signal based on the ET function. The transmit power of the transmit channel undergoes envelope tracking processing to provide an optimal voltage for each power point to reduce the energy of the voltage and thereby achieve power saving.

According to the uplink data transmission method of the embodiment of the present disclosure, the original uplink data packet can be encapsulated into at least two sub-data packets according to the uplink resources allocated by the network device to the electronic device and the maximum bandwidth supported by each radio frequency signal transmission channel, and at least The two sub-data packets are transmitted through the corresponding radio frequency signal transmission channel. During the transmission process, envelope tracking processing is performed based on the envelope tracking ET power module in the radio frequency signal transmission channel. It can be seen that the present disclosure can be applied to large bandwidth scenarios such as millimeter wave large bandwidth scenarios and uplink carrier aggregation. It can improve user perception and solve the problem of too small uplink coverage distance, allowing electronic devices to reside in 4G or 5G. superior. In addition, the present disclosure can realize the large-bandwidth ET function by setting the ET function in each radio frequency signal transmission channel, thereby improving the battery life of the electronic device and avoiding the frequent use of multiple antennas for diversity transmission.
