Description

A frequency modulation method and related equipment technical field

The embodiments of the present application relate to the technical field of communications, and in particular, to a frequency modulation method and related equipment.

Background technique

Due to the rapid development of communication technology, the 5th generation mobile communication technology (5G) has been widely used. 5G has higher requirements on the data transmission capability of the terminal (user equipment, UE), and requires the terminal to have relatively high high frequency. Therefore, in order to ensure that the feedback timing requirements of the protocol can be met, the terminal can only run at the highest frequency after entering the new radio (NR) connection state, which will lead to high power consumption of the terminal in the NR connection state. In this way, long-term high-power consumption and high-load operation will easily lead to increased power consumption of the terminal, shortened battery life, that is, shortened working hours of the terminal, and even seriously affect the service life of related devices.

Therefore, how to reduce the power consumption of the terminal is an urgent problem to be solved.

Contents of the invention

Embodiments of the present application provide a frequency modulation method and related equipment, which can reduce device power consumption and prolong the service life of the device.

The frequency modulation method provided in the embodiment of the present application may be executed by a terminal device or the like. A terminal device refers to a device that can be abstracted as a computer system, wherein a terminal device that supports a frequency modulation function may also be called a frequency modulation device. The FM device can be the complete machine of the terminal equipment, such as: smart wearable devices (such as smart watches, smart bracelets, smart helmets, smart glasses), smart phones, tablet computers, notebook computers, desktop computers, drones, Smart vehicles, on-board computers or servers, etc.; it can also be a system/device composed of multiple whole machines; it can also be some devices in the terminal equipment, for example: chips related to frequency modulation functions, such as system chips (system on a chip, SoC), etc., which are not specifically limited in this embodiment of the present application. Wherein, the system chip is also referred to as a system on chip.

In the first aspect, an embodiment of the present application provides a frequency modulation method, which is applied to a terminal device, where the terminal device includes N processing modules, and the current operating clock frequencies of the N processing modules are their respective first frequencies; The method includes: receiving downlink control information (DCI) sent by the base station; the DCI includes a target time interval; if the target time interval is less than or equal to a first preset value, the N processing modules The current operating clock frequencies of the M processing modules are increased from their respective first frequencies to their respective preset second frequencies; N is an integer greater than or equal to 1, and M is greater than or equal to 1 and less than or equal to N integer.

By using the method provided in the first aspect, the working clock frequency (or main frequency) of multiple processing modules (such as N processing modules) in the terminal device can be maintained at a low frequency (such as the respective first frequency) in advance, and According to the real-time scheduling situation of the base station, the dynamic frequency adjustment is carried out, and the main frequency is raised to a high frequency only when necessary. For example, only when the target time interval included in the DCI sent by the base station received by the terminal device is less than or equal to a certain preset value (for example, the first preset value), the terminal device needs to process the corresponding processing module (for example, the N processing The main frequency of the M processing modules in the module) is up-converted to make it run at its own high frequency (such as the second preset frequency), thereby improving the processing capability and processing speed of each processing module, so that it can A timely response is made within the smaller target time interval scheduled by the base station. In this way, the embodiment of the present application avoids unnecessary high-frequency operation of each processing module and reduces power consumption of the terminal device under the premise of ensuring reliable operation of the terminal device. Therefore, compared with the prior art, the terminal equipment cannot dynamically adjust the frequency, and in order to always meet the scheduling needs of the base station, the processing module in the terminal is always maintained at high frequency, resulting in high power consumption and high load. , the embodiment of the present application can dynamically adjust the main frequency of the corresponding processing module based on the actual situation of base station scheduling, thereby effectively reducing unnecessary power consumption, that is, reducing the overall power consumption of the terminal device, thereby reducing battery power consumption, and ensuring that the terminal device The working time is long, and the service life of related devices (such as modems, etc.) can be extended further, which greatly guarantees the user experience.

For example, a component may be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and/or a computer.

Communicate through local and/or remote processes.

First of all, some terms used in this application are explained to facilitate the understanding of those skilled in the art.

(1) K1, defined as the terminal from receiving the PDSCH scheduled by the base station (specifically, the PDSCH scheduled by the downlink control information (DCI) carried on the PDCCH sent by the base station) to the terminal feeding back the acknowledgment character (acknowledgement) to the base station character, ACK) or the time interval between negative response characters (non-acknowledge character, NACK) (specifically, the time interval in units of time slots (slots), for example, the interval of 1 slot or 2 slots, etc.). K1 indicates in the downlink DCI sent by the base station that the terminal needs to feed back ACK/NACK in time according to K1 scheduled by the base station. For example, the K1 scheduled by the base station can be one slot (that is, K1=1). In this way, after the terminal receives the PDSCH scheduled by the base station in the current slot (that is, receives downlink data on the transmission resources occupied by the PDSCH), it needs to receive the downlink data in the next slot. The corresponding ACK/NACK is fed back internally (that is, the interval is 1 slot). Wherein, generally, one slot may include 14 symbols (symbol).

It should be noted that in NR, the time offset K0 of PDSCH is also introduced, and the time offset K0 may also be included in DCI (it may be a time slot offset or a symbol offset). For example, the terminal receives DCI in slot1, and DCI includes K0=1, K1=1, then the terminal needs to receive downlink data on PDSCH in slot2, and feed back ACK/NACK to the base station in slot3. Wherein, slot3 is the next time slot of slot2, and slot2 is the next time slot of slot1. Furthermore, the terminal generally feeds back ACK through PUCCH or PUSCH. Therefore, the downlink DCI may also indicate the symbol position of PUCCH or PUSCH, for example, symbol 1, and the terminal needs to feed back ACK/NACK at symbol 1 on slot3.

(2) N1, defined as the minimum time interval between the terminal receiving the PDSCH scheduled by the base station and feeding back ACK/NACK to the base station (specifically, the time interval in units of symbols, for example, an interval of 10 symbols or 15 symbols, etc.). Optionally, the terminal can actively report its own N1 to the base station. Correspondingly, the base station can schedule the terminal based on the N1 reported by the terminal, specifically by sending downlink DCI to the terminal to indicate the corresponding K1. It should be understood that N1 represents the terminal's current (The smaller the N1, the higher the terminal processing capability and the faster the response (feedback ACK/NACK)), so in general, the K1 value scheduled by the base station will at least not be greater than the N1 value. For example, the terminal currently reports a support capability (capability) 1, and the reported N1 is 10 characters (that is, N1=10), then the K1 scheduled by the base station can be 1 slot (that is, K1=1, including 14 characters, greater than N1 ), so that after receiving the PDSCH scheduled by the base station in the current slot, the terminal can feed back the corresponding ACK/NACK in the next slot (that is, the interval is 1 slot). For another example, the terminal currently reports that it supports capability 2, and the reported N1 is 5 characters (that is, N1=5), then the K1 scheduled by the base station can be 0 slots (that is, K1=0), so that the terminal receives in the current slot After the PDSCH of the base station, the corresponding ACK/NACK must be fed back in the current slot (that is, the interval is 0 slots). Obviously, as mentioned above, capability 2 has stricter requirements on terminal processing timing than capability 1. At this time, the terminal is often required to run at the highest frequency to respond in time and feed back ACK/NACK.

(3) K2, defined as the time interval between the terminal receiving the PDCCH sent by the base station (specifically receiving the uplink DCI carried on the PDCCH) and sending the PUSCH to the base station (specifically sending uplink data on the PUSCH). K2 indicates in the uplink DCI sent by the base station that the terminal needs to send uplink data in time according to K2 scheduled by the base station. For example, the K1 scheduled by the base station may be one slot (that is, K1=1). In this way, after receiving the DCI carried on the PDCCH of the base station in the current slot, the terminal needs to start sending uplink data in the next slot.

(4) N2 is defined as the time interval between the terminal receiving the PDCCH sent by the base station and sending the PUSCH to the base station (specifically, sending uplink data on the PUSCH). Similarly, the terminal can actively report its own N2 to the base station. Correspondingly, the base station can schedule the terminal based on the N2 reported by the terminal, specifically by sending uplink DCI to the terminal to indicate the corresponding K2. It should be understood that N2 represents the terminal's current Processing capability (the smaller the N2, the higher the terminal processing capability and the faster the response (send uplink data)), so in general, the K2 value scheduled by the base station will at least not be greater than the N2 value. For example, the terminal currently reports that it supports capability1, and the reported N2 is 10 characters (that is, N2=10), then the K2 scheduled by the base station can be 1 slot (that is, K2=1, including 14 characters, greater than N2), so, After receiving the PDCCH of the base station in the current slot, the terminal can start to send corresponding uplink data in the next slot. For another example, the terminal currently reports that it supports capability2, and the reported N2 is 8 characters (that is, N2=8), then the K2 scheduled by the base station can be 0 slots (that is, K2=0), so that the terminal receives in the current slot After the PDCCH of the base station, the corresponding uplink data must be sent in the current slot. Obviously, as mentioned above, capability 2 has stricter requirements on terminal processing timing than capability 1. At this time, the terminal is often required to run at the highest frequency to send uplink data in time.

Optionally, for the definition of the above K1, K2, N1 and N2, specific reference may be made to relevant communication protocols (such as 3GPP TS 38.214), which will not be described in detail here.

To sum up, it should be noted that, in general, K1 and K2 are often greater than or equal to 2, that is, the terminal does not actually need to run at the highest frequency.

Only when the base station schedules K1 or K2=0, or K1 or K2=1 At this time, the terminal equipment needs to have high processing capacity and can respond quickly (such as drone control, telemedicine, and unmanned driving, etc.) and then increase the frequency to run at the highest or higher frequency. , at this time, the processor meets the processing requirements of tight timing, which can effectively prevent the terminal equipment from failing to process according to the timing required by the protocol, resulting in the retransmission of the base station and so on. In this way, compared with the conventional solution, in which the terminal always runs at the highest main frequency in order to ensure that the feedback timing requirements of the protocol can always be met, the embodiment of the present application can effectively avoid unnecessary high-frequency operation and reduce unnecessary Necessary power consumption, thereby prolonging the battery life, that is, prolonging the working hours of the terminal devices 100a, 100b, and 100c, and so on.

To sum up, the terminal devices 100a, 100b, and 100c may be the terminal device 100 shown in FIG. 1 or FIG. Smart watches, smart bracelets, smart helmets, smart glasses), and other devices with wireless access capabilities, such as smart vehicles, drones, servers, etc., will not be described here.

In order to facilitate the understanding of the present application, the application scenarios to which the frequency modulation method in the embodiment of the present application is applied are exemplarily listed below, which may include the following scenarios.

Please refer to FIG. 4a. FIG. 4a is a schematic diagram of an application scenario provided by an embodiment of the present application. As shown in FIG. 4a, the application scenario may include a base station 200, a control device 500, and multiple drones, specifically, drones 400a and 400b. The control device 500 can establish a wireless communication connection with the UAVs 400a and 400b through the base station 200, so as to control the motion flight of the UAVs 400a and 400b, as well as operations such as shooting and transmitting data, so as to complete corresponding shooting, exploration, testing or Tasks such as queue performances. Among them, the control device 500 and the UAVs 400a and 400b may include various components described in FIG. 3 , and a frequency modulation method provided in an embodiment of the present application may be used to dynamically adjust the main frequency of each according to the scheduling of the base station. Under the premise of ensuring the reliable operation of the UAV, reduce unnecessary power consumption.

It should be understood that in the UAV control scene similar to that shown in FIG. 4a, it is often necessary for the UAVs 400a and 400b to quickly respond to the instructions issued by the control device 500. If the processing speed of the UAVs 400a and 400b is slow, the control device If the 500 does not respond for a long time after sending the command, it will easily affect the accuracy of shooting, the accuracy of exploration, the viewing and safety of performances, etc. Therefore, for such scenarios requiring extremely low latency, the base station can perform extremely tight timing scheduling.

For example, please refer to FIG. 4b, which is a schematic diagram of another application scenario provided by the embodiment of the present application. As shown in Figure 4b, taking the control of UAVs to collect video data of real-time road conditions as an example, the application scenario may include multiple vehicles driving on the actual road, such as vehicle 1 (bus is taken as an example in Figure 4b), vehicle 2 (taking a car as an example in Figure 4b), vehicle 3 (taking a car as an example in Figure 4b) and vehicle 4 (taking a car as an example in Figure 4b). Further, this application scenario also includes drones 400a, 400b and control device 500, wherein user 600 can control drones 400a, 400b to fly smoothly through control device 500, and collect video data of real-time road conditions in the target area. Optionally, the collected video data can be uploaded to the server in real time (such as the cloud server of the entire transportation network, etc.), etc., and no further description will be made here. Specifically, after the drones 400a, 400b and the control device 500 are in the connected state, in order to ensure the reliability of the drone's work, the base station (such as the base station 200 in Figure 4a) can control the drones 400a, 400b and the control device 500 sends the corresponding DCI and schedules K1/K2=0. UAVs 400a, 400b and control device 500 are based on a frequency modulation method provided by this application. After recognizing K1/K2=0, they quickly increase the main frequency of their processors, and even run directly at the highest frequency. After the frequency is increased, the UAVs 400a and 400b can quickly respond to the instructions sent by the control device 400, and perform operations such as ascending, descending, advancing, turning, shooting, and transmitting data according to the instructions, so as to meet the accuracy of shooting and avoid endangering public places safety. Optionally, the UAVs 400a and 400b may include one or more cameras. After the frequency is increased, the UAVs 400a and 400b can quickly send the video data collected by the one or more cameras in real time to the The control device 500, correspondingly, the control device 500 may include a display, and the control device 500 can quickly receive the real-time video data and display corresponding pictures according to the received video data through the display, so that the staff can grasp the current real-time shooting situation ,etc.

To sum up, the control device 500 may be a wireless control device with the above-mentioned functions, such as a remote control, a smart phone, a tablet computer, a notebook computer, a desktop computer, a vehicle computer, a server, etc. Optionally, it may be a server, or it may It is a server cluster composed of multiple servers, or a cloud computing service center, etc., which are not specifically limited in this embodiment of the present application. The unmanned aerial vehicle may also be an intelligent vehicle with an unmanned driving function, etc., which is not specifically limited in this embodiment of the present application.

It can be understood that, in some possible embodiments, the frequency modulation method and related equipment provided by the embodiments of the present application can also be applied to other scenarios besides the above-mentioned drone control scenarios, such as telemedicine (such as including precision surgical instruments) Remote control) and unmanned driving (specifically, it can be applied to a vehicle-mounted computer, etc.) and other low-latency scenarios that require devices to respond quickly and in a timely manner, etc., etc., which are not specifically limited in this embodiment of the present application.

Please refer to FIG. 5. FIG. 5 is a schematic flowchart of a frequency modulation method provided by an embodiment of the present application. This method can be applied to the system architecture described in FIG. 3 above or the application scenarios described in FIGS. It can be applied to a terminal device (such as the terminal device 100 described in FIG. 1 or FIG. 2 above), the terminal device may include N processing modules, and the current working clock frequency (or main frequency) of the N processing modules may be respective first frequencies. The following describes with reference to FIG. 5 taking the execution subject as a terminal device as an example. The method may include the following steps S501-S502.

Step S501, receiving downlink control information DCI sent by the base station, where the DCI includes a target time interval.

Specifically, the terminal device receives the DCI sent by the base station, and the DCI includes the target time interval (that is, the aforementioned K1 or K2). For details, reference may be made to the aforementioned terminology explanation, which will not be repeated here.

Step S502, if the target time interval is less than or equal to the first preset value, then increase the current operating clock frequencies of the M processing modules in the N processing modules from their respective first frequencies to their respective preset second frequencies.

Specifically, the terminal device judges whether the target time interval in the currently received DCI is less than or equal to the first preset value based on the preset first preset value. If the target time interval is less than or equal to the first preset value (that is, K1 or K2 is less than or equal to the first preset value), the current operating clock frequency of the M processing modules in the N processing modules is changed from the respective first The frequencies are boosted to their respective preset second frequencies. Wherein, N is an integer greater than or equal to 1, and M is an integer greater than or equal to 1 and less than or equal to N. That is to say, after the terminal device in the embodiment of the present application enters the connected state, the main frequency of the multiple processing modules in it can be maintained at the default low-frequency gear, and only when receiving the tight timing schedule of the base station (that is, K1 or K2 is less than or equal to the first preset value), the terminal device increases the main frequency of the corresponding processing module to a high frequency to increase the processing speed and meet the tight timing processing requirements. In this way, the embodiment of the present application can dynamically adjust the main frequency of the corresponding processing module based on the actual situation of base station scheduling, thereby effectively reducing unnecessary power consumption, thereby reducing battery power consumption, ensuring the working hours of the terminal device, and further Prolonging the service life of related devices greatly guarantees the user experience.

Optionally, in this embodiment of the present application, when it is determined that the currently received target time interval is less than or equal to the first preset value, it is preferable to perform rapid upscaling processing, so as to avoid the current processing capability being still low due to slow upscaling. Therefore, it is impossible to feed back ACK/NACK or send corresponding uplink data within the smaller K1 or K2 scheduled by the base station, which ultimately affects the performance and work efficiency of the terminal equipment.

Optionally, the N processing modules may include one or more of a modem processor, an NR DL logic processing module, and an NR UL logic processing module, etc., and may also include, for example, a decoding module, etc. Examples are not specifically limited.

Optionally, the first preset value can be customized according to actual conditions or requirements, which is not specifically limited in this embodiment of the present application. It should be noted that, in general, K1 or K2=0, or K1 or K2=1 belongs to tight timing scheduling, which requires high processing capability of the terminal device, that is, requires the terminal device to respond quickly within a relatively short period of time.

Taking the downlink scenario as an example, the first preset value is, for example, 1. For example, the terminal equipment receives the downlink DCI in slot1, and the downlink DCI includes K0=1, then the terminal equipment needs to receive the PDSCH scheduled by the base station in the next adjacent slot (for example, slot2) of the slot1. At the same time, when K1 ≤ 1 included in the downlink DCI, that is, K1=0 or K1=1, in order to meet the tight timing processing requirements of the base station scheduling, the terminal device ensures that after the current slot (such as slot2) receives the PDSCH scheduled by the base station , can respond in time in the current slot (when K1=0) or the next slot (when K1=1), and feed back ACK/NACK to the base station. The respective main frequencies of one or more processing modules in the logic processing module etc. are up-converted. For example, increase the current main frequency of the modem processor from 1G to 2G, increase the current main frequency of the NR DL logic processing module and NR UL logic processing module from 100M to 200M, and so on.

Still taking the downlink scenario as an example, the first preset value is, for example, 0, and only when K1=0 included in the downlink DCI received by the terminal device, the terminal device guarantees to meet the extremely tight timing processing requirements of the base station scheduling. After the current slot receives the PDSCH scheduled by the base station, it can respond in time within the current slot and feed back ACK/NACK to the base station, and the terminal device can perform one of the modem processor, NR DL logic processing module and NR UL logic processing module, etc. or the main frequencies of the multiple processing modules to perform up-frequency processing.

Taking the uplink scenario as an example, if the first preset value is 1, for example, when K2≤1 included in the uplink DCI received by the terminal device, that is, K2=0 or K2=1, the terminal device must The timing processing requirements ensure that after the current slot receives the DCI sent by the base station, it can respond in time within the current slot (when K2=0) or the next slot (when K2=1), and send corresponding uplink data to the base station and terminal equipment Up-frequency processing can be performed on the respective main frequencies of one or more processing modules in the modem processor, NR DL logic processing module, and NR UL logic processing module. For example, increase the current main frequency of the modem processor from 1G to 2G, increase the current main frequency of the NR DL logic processing module from 100M to 200M, increase the current main frequency of the NR UL logic processing module from 100M to 300M, etc. wait. Optionally, in the uplink scenario, for the case where the first preset value is 0, reference may be made to the above-mentioned downlink scenario, and details are not repeated here.

Further, please refer to FIG. 6. FIG. 6 is a schematic flowchart of another frequency modulation method provided by the embodiment of the present application. This method can be applied to the system architecture described in FIG. 3 above or the application scenarios described in FIG. 4a and FIG. 4b , and specifically applicable to a terminal device (such as the terminal device 100 described above in FIG. 1 or FIG. 2 ). The following describes in detail with reference to FIG. 6 taking the execution subject as a modem in the terminal device as an example. The method may include the following steps S601-S610.

Step S601, receiving the DCI sent by the base station.

Specifically, for step S601, reference may be made to step S501 in the above-mentioned embodiment corresponding to FIG. 5 , and details are not repeated here.

Optionally, the terminal device may receive the DCI sent by the base station through a modem therein (such as the modem 102 shown in FIG. 2 ), and a processor in the modem (such as the modem processor 1021 shown in FIG. 2 ) may obtain the DCI K1 or K2 included in.

Optionally, as described above, the modem first operates at a relatively low main frequency gear in the connected state, for example, the current main frequencies of the N processing modules in the modem may be their respective first frequencies (low frequencies). For example, the current main frequency of the modem processor in the modem is 1G, the current main frequency of the NR DL logic processing module is 100M, the current main frequency of the NR UL logic processing module is 100M, and so on.

Step S602, judging whether K1 or K2 included in the DCI is less than or equal to a first preset value; if yes, execute step S603; otherwise, execute step S604.

Specifically, for step S602, reference may be made to step S502 in the above-mentioned embodiment corresponding to FIG. 5 , and details are not repeated here.

Optionally, taking the downlink scenario as an example, the modem processor judges whether K1 is less than or equal to the first preset value according to the obtained K1 and the preset first preset value (for example, 1); if so, Then execute step S603; otherwise, execute step S604.

Optionally, taking the uplink scenario as an example, the modem processor judges whether K2 is less than or equal to the first preset value according to the obtained K2 and the preset first preset value (for example, 1); if so, Then execute step S603; otherwise, execute step S604.

Step S603, if K1 or K2 included in the DCI is less than or equal to the first preset value, control the corresponding module to rapidly up-frequency, and update the number of up-frequency in the time window W2.

Specifically, for step S603, reference may be made to step S502 in the above-mentioned embodiment corresponding to FIG. 5 , and details are not repeated here.

Optionally, taking the downstream scenario as an example, the modem processor determines that K1 is less than or equal to the first preset value, and then controls the corresponding processing modules (such as the modem processor, NR DL logic processing module, NR UL logic processing module, etc.) rapidly up-converts its current main frequency from its respective first frequency to its respective preset second frequency. For example, increase the current main frequency of the modem processor from 1G to 2G, increase the current main frequency of the NR DL logic processing module from 100M to 200M, increase the current main frequency of the NR UL logic processing module from 100M to 300M, etc. wait.

Optionally, taking the uplink scenario as an example, the modem processor determines that K2 is less than or equal to the first preset value, and then controls the corresponding processing modules in the modem (such as the modem processor, NR DL logic processing module, NR UL logic processing module, etc.) rapidly up-converts its current main frequency from its respective first frequency to its respective preset second frequency. For example, increase the current main frequency of the modem processor from 1G to 2G, increase the current main frequency of the NR DL logic processing module from 100M to 200M, increase the current main frequency of the NR UL logic processing module from 100M to 300M, etc. wait.

For example, please refer to FIG. 7a, which is a schematic diagram of an overall process of a frequency modulation method provided by an embodiment of the present application. As shown in FIG. 7a , the downlink scenario and the first preset value equal to 1 are taken as an example in FIG. 7a , which will not be explained later.

As shown in FIG. 7 a , at 0 s, the modem receives ① DCI, including K1 = 0. At this time, up-frequency processing is performed to control the main frequency of multiple processing modules to increase to a high-frequency gear. At the same time, as shown in FIG. 7 a , the time window W1 (for example, the first time window) and the time window W2 (for example, the second time window) are started to be counted after it is recognized that K1≤1 (or after the current frequency up). It should be noted that the timing of the time window W2 can start from the first recognition of K1≤1 after the terminal device enters the connection state, and after the end of the current time window W2 (for example, ①W2), then continuously start counting the next time window W2 (such as ②W2), and so on, its timing is not affected by frequency up and frequency down. Optionally, the length of the time window W2 is set.

Optionally, as shown in Figure 7a, after identifying K1≤1 (or after this upscaling), update the number of upscalings in the current time window W2 (eg ①W2), optionally, this upscaling Include the number of upscaling times in the current time window W2. For example, as shown in Figure 7a, from the 0s to the 1s, the modem has only up-converted at the 0s, then up to the 1s, the number of up-conversions in the current ①W2 is 1.

Step S604, according to the received DCI, feed back ACK/NACK or send uplink data to the base station.

Specifically, taking the downlink scenario as an example, the modem decodes the received DCI, receives the downlink data sent by the base station on the scheduled PDSCH according to the decoded content, and feeds back the corresponding ACK/NACK to the base station within K1. Taking the uplink scenario as an example, the modem sends corresponding uplink data to the base station within K2 according to the received DCI.

Step S605, judging whether DCI including K1 or K2 less than or equal to the first preset value is received again within the time window W1; if yes, execute step S607; otherwise, execute step S606.

Specifically, as described above, after recognizing that K1≤1 (or after this up-frequency), start counting the time window W1, and judge whether to receive another signal including K1 or K2 less than or equal to the first time window W1 within the time window W1 Default DCI

Step S606, controlling the corresponding modules to perform frequency reduction processing.

Specifically, if within the time window W1, the modem has never received DCI including K1 or K2 being less than or equal to the first preset value, for example, including that the modem has never received DCI sent by the base station, or the received DCI contains Included K1 or K2 are all greater than the first preset value (such as K1 or K2 = 3, 4 or 5), then the current main frequency of multiple processing modules can be reduced from the respective preset second frequency to the respective first frequency. For example, reduce the current main frequency of the modem processor from 2G to 1G, reduce the current main frequency of the NR DL logic processing module from 200M to 100M, reduce the current main frequency of the NR UL logic processing module from 200M to 100M, etc. wait.

For example, as shown in Figure 7a, taking the time window W1 equal to 1s as an example, within the current ①W1, the modem sequentially receives ②DCI and ③DCI sent by the base station, but the K1 included in the two are 2 and 3, both greater than 1. Therefore, as shown in Figure 7a, if no scheduling of K1=0 or 1 is received within the current ①W1, then after ①W1 ends, that is, in the first s, the above-mentioned multiple processing modules are subjected to down-frequency processing to avoid unnecessary High-frequency operation reduces unnecessary power consumption.

For example, as shown in Figure 7a, after down-frequency processing is performed in 1s, the modem receives ④DCI in 1.5s, including K1=1, at this time, it can perform up-frequency processing on the above-mentioned multiple processing modules, and start timing ②W1 . Further, as shown in Figure 7a, the modem receives ⑤DCI in the 2s, including K1=0, so that, in the case of receiving the schedule of K1=0 or 1 in the current ②W1, it can continue to maintain high-frequency operation, and Restart the time window W1, which is the current ③W1.

For example, as shown in Figure 7a, after starting timing ③W1, within the current ③W1, the modem sequentially receives ⑥DCI and ⑦DCI sent by the base station, but K1 included in both is 2, both greater than 1. Therefore, as shown in Figure 7a, after the end of the current (3) W1, that is, at 3s, the above-mentioned multiple processing modules are subjected to down-frequency processing to avoid unnecessary high-frequency operation and reduce unnecessary power consumption.

For example, as shown in Figure 7a, after down-frequency processing in 3s, the modem receives DCI and DCI from the base station sequentially, but the K1 included in both are 3 and 2, both greater than 1. Therefore, low frequency operation is still maintained. Further, as shown in Figure 7a, the modem receives ⑩DCI at 4.4s, including K1=0, at this time, it can perform up-frequency processing on the above-mentioned multiple processing modules, and start timing ④W1.

Step S607, judging whether the number of times of upscaling within the time window W2 is less than or equal to a second preset value.

Specifically, count up-up times in the current time window W2, and judge whether the up-up times in the current time window W2 are less than or equal to the second preset value; if yes, execute step S608; otherwise, execute step S609.

It should be understood that in the embodiment of the present application, an entire upscaling process (including boosting the main frequencies of multiple processing modules) is counted as one upscaling.

Step S608, if the number of times of upscaling in the current time window W2 is less than or equal to the second preset value, shorten the time window W1.

Specifically, if the number of times of upscaling in the current time window W2 is less than or equal to the second preset value, the time window W1 is shortened, and the shortened time window W1 is used in the next time window W2.

For example, as shown in Figure 7a, taking the time window W2 equal to 5s as an example, the number of frequency upscaling in the current ①W2 is 3 times, and taking the second preset value equal to 5 as an example, it is obvious that the number of upfrequency in the current ①W2 is less than this The second preset value, therefore, the time window W1 can be shortened, specifically, the time window W1 can be shortened according to a preset range (for example, a first preset range, such as 0.2s) or a step length. As shown in Figure 7a, in the 5.4s of the subsequent ②W2 (ie, the 5th to the 10th s), since the DCI sent by the base station is not received in the ④W1, the frequency reduction processing can be performed on the above-mentioned multiple processing modules. Further, at the 6s in ②W2, the modem receives

DCI, including K1=1, at this time, the above-mentioned multiple processing modules can be up-converted, and start timing ⑤W1. Apparently, as shown in Figure 7a, since the up-frequency times in ①W2 are less than the second preset value, the current ⑤W1 is shortened to 0.8s, and at the same time, the modem only receives

DCI, including K1 = 4, so frequency down processing can be performed at 6.8s, etc., which will not be described here. In this way, unnecessary high-frequency running time can be shortened and unnecessary power consumption can be reduced under the condition of low frequency up-frequency.

Optionally, if the number of up-frequency in the current ②W2 is still less than the second preset value, the length of the time window W1 can be further shortened according to the preset range (for example, 0, 2s), then the time window in the subsequent ③W2 W1 may all be 0.6s, and so on, which will not be repeated here. Optionally, a minimum length (or a minimum threshold, such as 0.2s) may be preset for the time window W1, so that when the number of up-frequency in multiple time windows W2 is less than the second preset value, thus When the time window W1 is gradually shortened, it may not be further shortened when the time window W1 is shortened to the minimum threshold, so as to ensure sufficient high-frequency running time after each up-frequency to ensure reliable operation of the terminal equipment.

Step S609, if the number of times of upscaling in the current time window W2 is greater than the second preset value, then determine whether the number of times of upscaling in the time window W2 is greater than or equal to a third preset value.

Specifically, if the number of times of upscaling in the current time window W2 is greater than the second preset value, it is then judged whether the number of times of upscaling in the time window W2 is greater than or equal to the third preset value; if so, execute step S610, otherwise, The current length of the time window W1 is kept unchanged. Optionally, the second preset value may be equal to the third preset value. In this case, if the frequency of upscaling in the current time window W2 is less than the second preset value (ie, the third preset value), then the For the time window W1, if the number of up-frequency in the current time window W2 is greater than the second preset value (ie, the third preset value), the time window W1 can be extended; if the number of up-frequency in the current time window W2 is equal to the second preset value If the value is set (that is, the third preset value), the current length of the time window W1 can be kept unchanged.

Step S610, if the number of upscaling times in the time window W2 is greater than or equal to a third preset value, extend the time window W1.

Specifically, if the up-frequency times in the current time window W2 is greater than or equal to the third preset value, then the time window W1 is extended, and the extended time window W1 is used in the next time window W2.

Optionally, extending the time window W1 is the same as shortening the time window W1, and the specific process may refer to the description of the embodiment corresponding to FIG. 7a above, which will not be repeated here. For example, as shown in Figure 7a, the number of up-frequency of the modem in the current ①W2 is 3 times, if the third preset value is set to 3, then the number of up-frequency in the current ①W2 satisfies the requirement of being greater than or equal to the third preset value Conditions, the time window W1 may be extended according to a preset range (for example, a second preset range, such as 0.2s, 0.5s or 1s, etc.), for example, to 1.2s, 1.5s, or 2s.

Optionally, similar to the above method of shortening the time window W1, if the number of up-frequency in ②W2 is still greater than the third preset value, the time window W1 can be further extended according to the preset range (for example, 0.2s). length, then the time window W1 in the follow-up ③W2 can be 1.4s, and so on, which will not be repeated here. Optionally, a maximum length (or a maximum threshold value, such as 4s) can be preset for the time window W1, so that when the number of up-frequency in multiple time windows W2 is greater than the third preset value, gradually When the time window W1 is extended, it may not be extended when the time window W1 is extended to the maximum threshold, so as to avoid long-term high-frequency operation and reduce power consumption.

Optionally, the initial default length, minimum length, and maximum length of the time window W1, as well as its shortening range and extension range can be customized according to actual needs and situations. For example, the initial default length of the time window W1 is except for the 1s shown in Figure 7a , can also be 0.8s, 1.3s or 2s, etc.; for another example, the shortening range of the time window W1 can be 0.1s, 0.3s or 0.5s, etc. in addition to the 0.2s shown in Figure 7a; another example In addition to the 0.2s shown in FIG. 7a, the extension range of the time window W1 may also be 0.1s, 0.4s, or 0.5s, etc., which is not specifically limited in this embodiment of the present application. Similarly, the length of the time window W2 can also be customized according to actual needs and situations. In addition to 5s shown in FIG. 7a, it can also be 7s, 10s or 15s, etc., which is not specifically limited in this embodiment of the present application.

Optionally, please refer to FIG. 7b. FIG. 7b is a schematic diagram of an overall process of another frequency modulation method provided in an embodiment of the present application. As shown in FIG. 7b , the downlink scenario and the first preset value equal to 1 are taken as an example in FIG. 7b .

For example, as shown in Figure 7b, at 0s, the modem receives ①DCI, including K1=0, at this time, it performs up-frequency processing, controls the main frequency of multiple processing modules to increase to a high-frequency gear, and starts timing ①W1( Take 1s as an example).

Further, as shown in Figure 7b, at the 0.9th s in the current ①W1, the modem receives ②DCI sent by the base station, including K1=0, and continues to maintain high-frequency operation at this time, and starts timing ②W1 (for example, at 0.9s, the ①The timing of W1 is reset to zero, and the timing is restarted at 0.9s).

Further, as shown in Figure 7b, at the 1.8th second in the current ②W1, the modem receives ③DCI sent by the base station, including K1=1, and continues to maintain high-frequency operation at this time, and starts timing ③W1.

Further, as shown in Figure 7b, at the 2.7th second within the current ③W1, the modem receives ④DCI sent by the base station, including K1=1, and continues to maintain high-frequency operation at this time, and starts timing ④W1.

Further, as shown in Figure 7b, at the 3.6th second within the current ④W1, the modem receives the ⑤DCI sent by the base station, including K1=1, and continues to maintain high-frequency operation at this time, and starts timing ⑤W1.

Further, as shown in Figure 7b, at the 4.5th second within the current ⑤W1, the modem receives ⑥DCI sent by the base station, including K1=1, and continues to maintain high-frequency operation at this time, and starts timing ⑥W1.

To sum up, in the current ①W2 (0th to 5th s), the modem has received the schedule of K1=0 or 1 in each time window W1, so after the 0th up-frequency, it always maintains high-frequency operation, that is Its up-frequency frequency within the current ①W2 is only 1 time. In this way, taking the second preset value equal to 3 as shown in FIG. 7 b as an example, since ① the number of upsampling times in W2 is less than the second preset value, the time window W1 can be shortened according to the preset range. As shown in Figure 7b, at the 5.4th s in the subsequent ②W2 (that is, from the 5th to the 10th s), the modem receives ⑦DCI sent by the base station, including K1=0, at this time, the up-frequency processing is performed and the timing ⑦W1 is started. Apparently, as shown in Figure 7b, since the number of up-frequency in ①W2 is less than the second preset value, the current ⑦W1 is shortened to 0.8s, and at the same time, because the modem does not receive The DCI sent by the base station can be down-frequency processed in 6.2s. It can be seen from this, please refer to Figure 7b further, if in the current ②W2, the base station always sends the schedule of K1=0 or 1 every 0.9s, then in ②W2, the modem will perform frequent up- and down-frequency, specifically Therefore, the modem will perform up-conversion processing (5 times in total) at 6.3s, 7.2s, 8.1s, 9s, and 9.9s respectively. Thus, taking the third preset value equal to 4 as shown in Figure 7b as an example, since ①W2 The number of times of up-frequency within is greater than the third preset value, so the time window W1 can be extended according to the preset range. For example, it can be extended to 1s, so as to avoid frequent frequency up and frequency down operations, and reduce device power consumption and workload.

As mentioned above, by continuously counting the number of up-frequency in each subsequent second time window, the length of the above-mentioned first time window can be continuously adjusted, and finally a balance point can be reached, which can maintain a suitable high-frequency running time and avoid long Unnecessary high-frequency operation for a long time can avoid frequent down-frequency and up-frequency.
