[0026] As described in the background art, the current digital radio frequency series control interface does not fully meet the requirements of the narrowband Internet of Things. There is an urgent need for a radio frequency control solution applicable to the narrowband Internet of Things.

[0027] This application realizes flexible configuration of RF timing through an event trigger mechanism, thereby achieving flexible control of RF devices. It improves the RF control solution based on the digital RF series control interface and is applicable to low-rate networks such as narrowband IoT. In addition, the RF control system of this application controls RF devices by configuring events and triggering events, without additional hardware, reducing the hardware cost of RF control.

[0028] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of specific embodiments of the present invention will be given with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work belong to the scope of protection of the present invention.

[0029] See Figure 1 , the RF control system provided by this application includes a counting module 101, an event generation module 102, and a register control module 103.

[0030] Among them, the counting module 101 is used to count according to the event configuration period. The event generation module 102 is used to generate RF control events in the next event configuration period within the current event configuration period. Each RF control event has an effective time and an event identifier. The register control module 103 is used to write RF control events in different event configuration periods into different buffer areas, and when the effective time of the RF control event in the current event configuration period is the same as the count of the counting module, trigger the control signal corresponding to the event identifier of the RF control event, so that the control signal controls the corresponding RF device.

[0031] In this embodiment, when the counting module 101 counts according to the event configuration period, within the event configuration period, the count value of the counting module 101 increases. When the next event configuration period starts, the count of the counting module 101 starts counting from zero. For example, the length of the event configuration period is TCU_WrapVal, and the counting module 101 starts counting from 0. When the count value reaches TCU_WrapVal, the counting module 101 starts counting from 0 again.

[0032] In a specific embodiment, the event configuration period is related to the time length of the radio frame or radio sub-frame of the network mode and the sampling frequency. The specific value of the event configuration period can be adaptively configured according to the actual application scenario, and this application does not limit this.

[0033] Furthermore, the counting method of the counting module 101 can be further extended. The counting module 101 counts according to the event configuration period in each counting period. The counting period can be set according to the frame or sub-frame.

[0034] In specific implementation, the counting module 101 performs periodic counting according to the configured counting period (counting period = TCU_SfWrapVal + 1). The event configuration period is TCU_WrapVal + 1. In this case, two counters are required. One counter, tcu_sf_counter, counts according to the counting period, and the other counter, tcu_counter, counts according to the event configuration period. Both counters tcu_counter and tcu_sf_counter start counting from 0. When the count value of tcu_counter reaches TCU_WrapVal, tcu_counter restarts counting from 0, and at the same time, the count value of tcu_sf_counter is updated to (tcu_sf_counter + 1) % (TCU_SfWrapVal + 1).

[0035] In a specific application scenario, for narrowband Internet of Things, the counting period can be set as the number of sub-frames within a radio frame, that is, the counting period is 10.

[0036] In this embodiment, the event generation module 102 can generate radio frequency control events serially or in parallel. Specifically, generating a radio frequency control event can be to control whether the pulse level corresponding to the radio frequency control event is high level or low level. The output of the radio frequency control event can be enabled and controlled through a hardware enable signal.

[0037] In specific implementation, the event generation module 102 can use a comparator to generate all events in beats. The event generation module 102 uses 5 comparators, which are divided into 12 beats. Each beat gives 5 comparison results, and each result can trigger 43 events. Among them, Event[23:0] is a time control operation event. Event[2×i] controls the time control operation event Event[i] to be '0', and Event[2×i + 1] controls the time control operation event Event[i] to be '1', where i ∈ [11:0]. Event[42:24] controls other event control events to become '1' and changes to '0' when the next clock pulse arrives.

[0038] In a non-limiting embodiment of the present application, the event generation module 102 may include a comparison unit, and the comparison unit is used to compare whether the effective time of all radio frequency control events within the current event configuration period is the same as the count of the counting module 101.

[0039] In the embodiment of the present application, by comparing the effective time of all events with the count value of the counting module 101, such processing can support out-of-order submission of radio frequency control events (events), and can enhance the robustness of the radio frequency control system.

[0040] In this embodiment, the radio frequency control event is a hardware signal that can be configured to take effect at a specific moment. Each radio frequency control event has an effective time (eventTime) and an event identifier (eventId). The effective range of the effective time is [0, TCU_WrapVal], where TCU_WrapVal is the length of the event configuration period, and the event identifier (eventId) is defined by the radio frequency control system itself.

[0041] Specifically, the configurable radio frequency control events include, but are not limited to, SPI command trigger events, radio frequency data interface enable events, radio frequency data interface disable events, digital front-end module enable and digital front-end module disable events, etc. This application does not limit this.

[0042] Continue to refer to Figure 1 , the register control module 103 can complete the reading and writing of registers and the configuration of the trigger time of radio frequency control events.

[0043] In a specific implementation, the event generation module 102 can compare whether the count value of the counting module 101 is the same as the effective time of each radio frequency control event. When they are the same, the register control module 103 triggers the hardware signal corresponding to the event identifier, and the hardware connected to the signal is triggered to work by the hardware signal.

[0044] The radio frequency control events in different event configuration periods may overlap. If all radio frequency control events are placed in the same buffer area, it may cause the radio frequency control events with earlier generation times to be overwritten by the radio frequency control events with later generation times, affecting the normal operation of the radio frequency device. In the embodiment of this application, by writing the radio frequency control events in different event configuration periods into different buffer areas, the coverage of the same radio frequency control event can be avoided, ensuring the normal operation of the radio frequency device.

[0045] Furthermore, the register control module 103 may include a validity check unit, which is used to perform a validity check on the generated radio frequency control events and write them into the buffer area when the radio frequency control events are valid.

[0046] In a specific embodiment, the buffer area includes a first buffer area and a second buffer area. The register control module 103 writes the radio frequency control events in the next event configuration period into the first buffer area, and writes the radio frequency control events in the next event configuration period into the second buffer area when the count of the counting module 101 reaches the maximum value. For example, the first buffer area is the ProgrammedEvent area, and the second buffer area is the ActiveEvent area.

[0047] In specific implementation, the radio frequency control event is first written into the temporary event buffer by writing to the register, and the validity check unit will perform a validity check on the radio frequency control event. After confirming that the radio frequency control event is valid, the register control module 103 writes the radio frequency control event into the first buffer area at the corresponding address according to the internal address parameter. After confirming that the event is invalid, the register control module 103 will mark the event as an invalid event and not write it into the first buffer area.

[0048] In addition, the register control module 103 also provides configurations and operations for clearing the temporary event buffer and the first buffer area. Through the above operations, the configuration or clearing of the first buffer area is completed.

[0049] Specifically, the first buffer area can be a buffer area customized by the radio frequency control system, and its design parameters can be optimized according to the specific wireless network system. For narrowband Internet of Things, when the counting module 101 simultaneously uses sampling counting and sub-frame number counting (usually with a value of 10), the first buffer area and the second buffer area can be evenly divided into sub-areas according to the counting period, and the number of events that each sub-area can accommodate needs to be greater than the maximum number of events that may occur within each sub-frame period of the radio frequency system. When the counting module 101 only uses sampling counting, the first buffer area and the second buffer area can be divided into multiple sub-areas according to the event type.

[0050] Refer to together Figure 2 , Figure 2 shows a schematic structural diagram of the buffer area in the present application. Among them, when the counting module 101 simultaneously uses sampling counting and sub-frame number counting, the counting period is 7; or, when the counting module 101 only uses sampling counting, the number of event types is 7. In this case, the first buffer area can be divided into 7 first buffer sub-areas, that is, the first buffer sub-areas 0, 1,..., 7. Correspondingly, the second buffer area is divided into 7 second buffer sub-areas, that is, the second buffer sub-areas 0, 1,..., 7. The radio frequency control event in the first buffer sub-area 0 can be copied to the second buffer sub-area 0. Similarly, the radio frequency control event in the first buffer sub-area 1 can be copied to the second buffer sub-area 1, and the radio frequency control event in the first buffer sub-area 7 can be copied to the second buffer sub-area 7.

[0051] Specifically, when the counting module 101 counts to the end of the event configuration period and the identification bit of the radio frequency control system allows the copy operation, the register control module 103 will copy all the radio frequency control events in the first buffer area to the second buffer area. Otherwise, the register control module 103 can perform a forced copy operation through configuration to copy the first buffer area to the second buffer area. If the forced copy operation is not configured, the register control module 103 can clear the corresponding second buffer area.

[0052] In another specific embodiment, the buffer region includes a third buffer region and a fourth buffer region. The register control module 103 writes the radio frequency control events generated during the current event configuration cycle into the third buffer region, and writes the radio frequency control events to be generated in the next event configuration cycle into the fourth buffer region.

[0053] Specifically, in the embodiments of the present application, the third buffer region and the fourth buffer region can be referred to as a ping-pong buffer. In this case, the register control module 103 needs to additionally indicate the currently active buffer region. The currently active buffer region refers to the buffer region in which the radio frequency control events will be executed.

[0054] Compared with the first buffer region and the second buffer region in the foregoing embodiment, the present application can avoid event copying operations.

[0055] Please refer to Figure 3 , Figure 3 , which shows another structure of the radio frequency control system.

[0056] Different from the radio frequency control system shown in Figure 1 , the radio frequency control system of the present application further includes a clock generation module 104, and the clock generation module 104 is used to generate a corresponding operating clock frequency according to the current network mode.

[0057] In specific implementation, for different wireless network modes, the clock generation module 104 can be configured to generate different operating clock frequencies. For the Global System for Mobile Communications (GSM), the clock generation module 104 can generate a frequency of 1.08 MHz or an integer multiple thereof; for the Narrowband Internet of Things, the clock generation module 104 can generate a frequency of 1.92 MHz or an integer multiple thereof.

[0058] The radio frequency control system of the present application further includes a power consumption control module 105, and the power consumption control module 105 is used to generate an enable control signal to control the radio frequency device to enter the sleep state.

[0059] In specific implementation, the power consumption control module 105 can control the radio frequency device to enter the sleep state by configuring registers and switching state machines. For example, the power consumption control module 105 can implement the enable control of the SPI; the power consumption control module 105 can implement the frequency calibration of the operating clock and the sleep clock; the power consumption control module 105 can also inform other modules of the current state of the radio frequency control system through the status register; the power consumption control module 105 can also control external radio frequency and phase-locked loop devices, etc.

[0060] The radio frequency control system of the embodiments of the present application can be used for GSM and narrowband Internet of Things chips. Through the radio frequency control system, the hardware enable signal can be triggered at a specified moment, and the hardware enable signal triggers the operation of hardware such as SPI and Decision Feedback Equalizer (DFE), and they cooperate with each other to complete the precise time control of radio frequency operations.

[0061] Please refer to Figure 4 , the present application also discloses a radio frequency control method, which may include:

[0062] Step 401: Count according to the event configuration period;

[0063] Step 402: Generate radio frequency control events in the next event configuration period within the current event configuration period, and each radio frequency control event has an effective time and an event identifier;

[0064] Step 403: Write the radio frequency control events in different event configuration periods into different buffer areas, and when the effective time of the radio frequency control event in the current event configuration period is the same as the count of the counting module, trigger the control signal corresponding to the event identifier of the radio frequency control event, so that the control signal controls the corresponding radio frequency device.

[0065] It should be noted that the sequence numbers of the steps in this embodiment do not represent the limitation of the execution sequence of each step.

[0066] It can be understood that in specific implementation, the radio frequency control method can be implemented in the form of a software program, and the software program runs in a processor integrated inside a chip or a chip module. This method can also be implemented in the form of software combined with hardware, and the present application does not make any restrictions.

[0067] In a specific implementation manner of step 403, the radio frequency control events in the next event configuration period can be written into the first buffer area, and when the count of the counting module reaches the maximum value, the radio frequency control events in the next event configuration period are written into the second buffer area.

[0068] In another specific implementation manner of step 403, the radio frequency control events generated in the current event configuration period can be written into the third buffer area, and the radio frequency control events generated in the next event configuration period are written into the fourth buffer area.

[0069] In a specific embodiment, after step 402, the following steps may further be included: Compare whether the effective times of all radio frequency control events in the current event configuration period are the same as the count of the counting module.

[0070] In the specific implementation of step 401, counting is performed according to the event configuration period within each counting cycle; the buffer area includes a plurality of sub-areas, and the number of sub-areas is consistent with the value of the counting cycle.
