Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are illustrative of the relevant application and are not limiting of the application. It should be noted that, for the convenience of description, only the parts related to the related applications are shown in the drawings.
In current fourth Generation wireless communication technology (4G)/fifth Generation mobile communication technology (5G) mobile communication systems, an uplink radio frequency of a User Equipment (UE) needs to open/close a path or update parameters within a configuration time window according to a third Generation Partnership Project (3 GPP) protocol. With the evolution of the 5G protocol, especially for the scenario of Ultra-reliable and low-latency communications (URLLC), the uplink of the UE requires a scheduling design with more flexible time granularity.
In the 4G Long Term Evolution (LTE) era, the time granularity of uplink scheduling is in subframes (subframes), and the interval of such scheduling is in the order of milliseconds. However, in the New Radio (NR) era of 5G, URLLC needs to consider symbol (symbol) level scheduling, i.e. microsecond level scheduling. The problem with microsecond-level scheduling is that a control system of a Modem needs to perform scheduling in real time, compactly and quickly, otherwise, the whole scheduling timing is not in time, and thus the 3GPP specification cannot be met.
In the LTE protocol, a Downlink Control Information (DCI) position and a corresponding Physical Downlink Control Channel (PDCCH)/Physical Uplink Shared Channel (PUSCH) are relatively fixed, and for a Downlink, the DCI and the PDSCH are definitely on the same subframe; for most uplink, PUSCH appears on the 4 subframes after the corresponding DCI. For example, the Worst case analysis (Worst case) is that the DCI of the current subframe schedules PUSCH transmission of the next subframe. The scheduling interval is in units of subframe, i.e., milliseconds.
NR supports more flexible resource scheduling, and the relative position of PUSCH and DCI is no longer fixed in the time domain. And the NR indicates the time domain distance between the PUSCH and the DCI through K2 (the value range is 0-32). K2 ═ 0 indicates that the PUSCH is on the same slot (slot) as the DCI, K2 ═ 1 indicates that the PUSCH is on the slot after the DCI, and so on. For example, fig. 1 is a schematic diagram of the interval time, as shown in fig. 1, the interval time T of the PDCCH and the PUSCH scheduled by the PDCCHproc,2The shortest scheduling interval time in (1) is 196us (5.5 symbols). The protocol 3GPP 38.214(6.4) specifies that the interval time from the completion of PDCCH reception to the scheduling of PUSCH transmission can be expressed as the following formula:
Tproc,2=max((N2+d2,1+d2)(2048+144)·κ2·TC+Text+Tswitch,d2,2) (1)
wherein, PUSCH preparation time (PUSCH preparation time) N2In relation to subcarrier spacing μ, UE capability, specifically, table 1 shows N under UE capability 1(capability1)2A correspondence with μ, wherein, for the case where the UE capability is capability1, when the subcarrier spacing μ is 0, N is210, when the subcarrier spacing μ is 1, N 212, when the subcarrier spacing μ is 2, N 223 when the subcarrier spacing μ is 3When N is present2Is 36.
Table 2 shows N under UE capability 2(capability2)2A correspondence with μ, wherein, for the case where the UE capability is capability2, when the subcarrier spacing μ is 0, N is2Is 5, when the subcarrier spacing mu is 1, N2Is 5.5, when the subcarrier spacing μ is 2, for N of frequency range 12Is 11.
As is clear from tables 1 and 2, when μ is 1, N2 is the smallest at capacity 2.

If the first symbol of PUSCH only has Demodulation Reference Signal (DMRS), then d2,1Not more than 0, otherwise d2,1=1;d2The minimum value is 0 related to the priority of PUSCH and PUCCH; κ is defined as 64 in the protocol 3GPP 38.211; t isextTaking values according to a protocol when sharing the frequency spectrum, wherein the minimum value is 0; t isswitchThe minimum value is 0; d2,2And a minimum of 0 is taken according to a protocol value in relation to Bandwidth Part (BWP) handover.
It can be seen that the time required for the upstream preparation process is mainly N2Related, and the minimum value is 5.5symbols (μ ═ 1). For a normal Cyclic Prefix (CP), 5.5symbols are approximately 196 us.
Fig. 2 is a diagram illustrating an uplink preparation procedure, which is configured such that the UE capability is capability2 (capacity 2), the Frequency Range (FR) is FR 1, and the PDCCH subcarrier spacing (SCS) is 60 Kilohertz (KHZ), as shown in fig. 2.
In the uplink preparation process, the UE needs to complete the following preparation work:
1. PDCCH decoding (decoder), wherein the current decoder time is about 1.5 symbols, i.e., 53 us; the delay caused by Hardware design (Hardware, HW) is difficult to shorten.
2. L1C analyzes configuration actions such as DCI and UL Grant (physical control information), and belongs to Software design (SW) operations.
3. L1C notifies a Transmit (TX) module to prepare to transmit data, and notifies a Radio Frequency control (RF controller) module to prepare to turn on an upstream RF, belonging to SW operation.
4. The RF controller configures RF and stabilizes a Phase Locked Loop (PLL) before transmitting PUSCH. Wherein the stabilization time of most current models of the device is about 100 us; this time is the time required for HW and is difficult to shorten.
5. After receiving the configuration request, the RF controller calculates and acquires parameters needed by configuration, combines the parameters with the existing configuration tasks, generates the configuration tasks according to the device interface requirements and the like; belonging to SW operation.
Based on the above figure, the shortest scheduling interval determined based on the 3GPP specifications is 196us, while the time for HW operation is 53+100 ═ 153us, so the time left for all SWs is 196-. Considering the processing of the various sub-modules SW and the message interaction of the sub-modules, the time left for the RF controller may be less than 43 us.
The existing solution is that the RF controller module dynamically modifies, merges or cancels the already configured transmission according to the current real-time received message. For example, fig. 3 is a scheduling diagram, and as shown in fig. 3, for a scenario of URLLC, a common scheduling procedure is as follows:
s1, the RF controller receives the message.
And S2, calculating parameters needed for obtaining the configuration link.
And S3, task arbitration is carried out.
And S4, arranging the task execution sequence according to the scheduling requirement and configuring the link.
Specifically, after receiving the message, the RF controller may calculate and obtain all parameters required for configuring the link according to the received message, and then perform the task arbitration process. For example, an existing task is queried and a determination is made as to whether there is an association with the current task. If there is a conflict between the existing task and the current task, the existing task needs to be undone (S31), otherwise, the existing task needs to be merged (S32) or a new task is generated (S33). After the task arbitration process is completed, the task execution order may be arranged according to the scheduling requirement; and may begin configuring the link.
If the existing task conflicts with the current task, the task list can be operated firstly, and the conflicting existing task is deleted from the task list; and then converting the parameters into new configuration tasks according to the drive format according to all the acquired parameters, so that the new tasks can be added to the task queue. If there is a relationship but there is no conflict between the existing task and the current task, the new configuration parameters can be directly updated to the corresponding task according to the driving format. If the existing task is not related to the current task, the existing task can be converted into a new configuration task according to all acquired parameters and a driving format, and then a task list can be operated to add the new task to a task queue.
Therefore, for the current scheduling scheme, after each message is received, the related operations as described above need to be processed once, so that the upper-layer service is limited to be scheduled on a smaller time granule, and the user experience is affected. Especially for the scenario where N2 equals 5.5symbols, the configuration timing is more stressed.
For example, fig. 4 is a schematic diagram of a scenario of task configuration, and as shown in fig. 4, it is assumed that the task configuration may be implemented based on the following scenario conditions: two configuration messages Msg, Msg1 and Msg2, are received at slot N, and one Msg, Msg3, is received at slot (N +1), wherein Msg1, Msg2 and Msg3 are all scheduled for slot (N +1) transmission. Specifically, a Slot N Slot header Msg1 indicates that Slot (N +1) symbols 4-8 have an uplink transmission request; msg2 indicates slot (N +1) symbols 2 and 3 also have uplink sending requests; msg3 indicates that symbols 12, 13 have a request to send.
Fig. 5 is a schematic diagram of a common implementation framework of task configuration, and as shown in fig. 5, for a scenario condition shown in fig. 4, when task configuration is performed at present, the following parts may be mainly processed based on a message sending list, a task creating module, a task scheduling module, and the like:
(1) received Msg 1:
a) a Task4 is created, and the Task4 is used for opening and configuring an uplink path in front of the symbol 4;
b) task8 is created, and Task8 is used to close the upstream path at the end of symbol 8.
(2) Received Msg 2:
a) checking the existing tasks Task4 and Task8, and determining that the path opening time conflicts with Task 4;
b) revocation Task 4;
c) a Task2 is created, the Task2 is used to open and configure the upstream path before symbol 2;
d) and Task sequencing, wherein the Task scheduling module is informed of the execution sequence of Task2 and Task 8.
(3) Received Msg 3:
a) checking the existing tasks Task2 and Task8, and determining that no Task conflict exists;
b) a Task12 is created, the Task12 is used for opening and configuring an uplink path in front of the symbol 12;
c) a Task13, the Task13 being used to close the upstream path at the end of symbol 13;
d) and Task sequencing, namely informing the Task scheduling module of the execution sequence of Task2, Task8, Task12 and Task 13.
Therefore, the existing scheduling scheme is a passive scheduling mode, the scene combination is too many, and the logic is complex.
If the RF controller can be completed quickly, more processing time can be left for other sub-modules; or the clock (clock) of the HW can be reduced to achieve the purpose of saving power.
Specifically, in order to solve the above problem, in the embodiment of the present application, after a new scheduling task of a target time slot is generated based on a pre-generated working template of one or more time domain symbols in the target time slot, the new task addition processing and the modification processing of the scheduled task that conflicts with the new task may be implemented only by updating the corresponding working template according to configuration parameters of the scheduling task, that is, the control of the working state of the radio frequency front end may be completed through the working template, and meanwhile, triggering of different tasks of the target time slot may be performed based on the sequence of the time domain symbols in the target time slot, so as to omit the process of sequencing different tasks. Therefore, the method for controlling the radio frequency front end provided by the embodiment of the application greatly reduces the complexity of task configuration, shortens the time of task configuration, further realizes the control processing of the radio frequency front end with high speed and high efficiency, and improves the communication performance
That is to say, for the requirement of fast completion of the RF controller, the present application provides a control method of a radio frequency front end, which is a normalized control method, and the control method is stable, reliable, and low in delay, and is particularly suitable for uplink radio frequency scheduling of a symbol-level UE in a URLLC scenario.
It should be noted that, the control method of the radio frequency front end provided in the present application takes the uplink direction of a wireless communication terminal (such as a mobile phone, etc.) as an example to describe a scheme. But the control method of the rf front end is not limited to this scenario. The control method of the radio frequency front end provided by the application can also be applied to any other scenes. This application is not particularly limited.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
An embodiment of the present application provides a method for controlling a radio frequency front end, and fig. 6 is a schematic implementation flow chart of the method for controlling the radio frequency front end, as shown in fig. 6, in the embodiment of the present application, the method for controlling the radio frequency front end may include the following steps:
step 101, determining a target time slot corresponding to a scheduling task; and one or more time domain symbols in the target time slot are respectively configured with a working template.
In the embodiment of the present application, the control device may first determine a target timeslot corresponding to the scheduling task. In the embodiment of the present application, the target time slot is a time slot in which the radio frequency front end sends an uplink signal corresponding to the scheduling task, and the target time slot may be a time slot in which the scheduling task is received; alternatively, the target time slot may be a time slot after receiving the scheduling task. That is, in the embodiment of the present application, a scheduling task that acts on one time slot may be received in the one time slot, or a scheduling task that acts on another time slot after the one time slot may be received in the one time slot.
Specifically, one or more time domain symbols in the target time slot are respectively configured with corresponding working templates. It should be noted that, in the embodiment of the present application, the working template corresponding to one or more time domain symbols in the target timeslot is preconfigured according to the interface parameters and the scene parameters of the radio frequency front end.
For example, in the embodiments of the present application, the interface parameters of the rf front end may be used to determine the interface format of the device, where the device may include a switch, an amplifier, a filter, and the like. The scene parameters may be used to determine a current service scene of the physical layer, where the service scene of the physical layer includes a measurement scene, a transmission scene, and the like.
Further, in the embodiment of the present application, the interface parameter and the scene parameter may be determined in a time slot before the target time slot. And then generating a working template corresponding to one or more time domain symbols in the target time slot according to the interface parameters and the scene parameters, namely generating the working template corresponding to one or more time domain symbols in the target time slot.
It should be noted that, in the embodiment of the present application, each slot (slot) includes 14 time domain symbols, that is, 14 symbols (symbols), where each time domain symbol may be a start point or an end point of data transmission, for example, each symbol may be a potential start of transmission or an end of transmission.
Further, in the embodiment of the present application, the working template is corresponding to a time domain symbol in the target time slot, and specifically, for the target time slot, the terminal may generate at least one working template corresponding to at least one time domain symbol in the 14 time domain symbols in the target time slot in advance. For example, the terminal may generate 5 working templates corresponding to the first 5 time domain symbols in the target slot.
It can be understood that, in the embodiment of the present application, in order to establish the work template for the target timeslot in advance, the interface parameters and the scenario parameters need to be determined first. The interface parameters may be used to determine a device interface format, and the scenario parameters may be used to determine a service scenario of the physical layer.
It should be noted that, in the embodiment of the present application, the working template corresponding to one or more time domain symbols in the target time slot is generated in advance, that is, the working template is generated before the target time slot. Generally, since the operating parameters of the rf chip in each timeslot may be different, the baseband chip may configure the operating parameters of each timeslot of the rf chip in other timeslots before the timeslot.
Further, in an embodiment of the present application, each working template includes an enabling parameter, where the enabling parameter is used to indicate whether the radio frequency front end is enabled in a time domain symbol corresponding to each working template; wherein the enabling parameters in each pre-configured working template are configured to be disabled. And step 102, adjusting the working template of one or more time domain symbols in the target time slot according to the scheduling task.
In the embodiment of the present application, after determining the target time slot corresponding to the scheduling task, the working template of one or more time domain symbols in the target time slot may be further adjusted according to the scheduling task.
It should be noted that, in the embodiment of the present application, it may be determined whether a scheduled task exists in a target time slot, and if the scheduled task exists and the scheduled task conflicts with a received scheduled task, the working template of one or more time domain symbols in the target time slot needs to be modified; if the scheduled task does not exist or the scheduled task does not conflict with the received scheduled task, only the configuration parameters corresponding to the scheduled task need to be added into the corresponding working template.
It is understood that, in the embodiment of the present application, if a scheduled task existing in a target time slot is the same type as a received scheduled task and corresponds to the same time domain symbol in the target time slot, it may be considered that a scheduled task conflicts with the received scheduled task. For example, when the scheduled task existing in the target timeslot includes uplink transmission on the time domain symbol 8 and the received scheduled task also includes uplink transmission on the time domain symbol 8, it may be determined that there is a collision between the scheduled task and the received scheduled task.
Accordingly, in the present application, if a scheduled task existing in a target time slot is of a different task type than a received scheduled task, or both correspond to different time domain symbols in the target time slot, then it may be assumed that there is no conflict between the scheduled task and the received scheduled task.
It should be noted that, in the embodiment of the present application, after the scheduling task is configured through the work template of at least one time domain symbol in the target time slot, for the work template to which the task configuration parameter of the new task is added, the enable parameter corresponding to the work template may be set as enable.
It can be understood that, in the embodiment of the present application, if the enable parameter of the working template of at least one time domain symbol in the target time slot is enable, it may be determined that a scheduled task exists in the target time slot, and at the same time, a task corresponding to the at least one time domain symbol may be determined as the scheduled task of the target time slot; correspondingly, if the enabling parameters of the working templates of one or more time domain symbols in the target time slot are all disabled, it can be determined that the target time slot does not have any scheduled taskAffairs
Optionally, in an embodiment of the present application, when the working template of one or more time domain symbols in the target time slot is adjusted according to the scheduling task, and when the scheduling task conflicts with the scheduled task in the target time slot, an update configuration of an enable parameter in the working template of the time domain symbol corresponding to the scheduled task may be selected as not to be enabled; and then, the scheduling task can be added to the working template of the time domain symbol corresponding to the scheduling task according to the configuration parameters of the scheduling task, and the enabling parameters of the working template of the time domain symbol corresponding to the scheduling task are updated and configured to be enabled.
Optionally, in an embodiment of the present application, when the working templates of one or more time domain symbols in the target time slot are adjusted according to the scheduling task, when the scheduling task does not conflict with a scheduled task in the target time slot, or when the scheduled task does not exist in the target time slot, the scheduling task may be directly added to the working template of the time domain symbol corresponding to the scheduling task according to the configuration parameter of the scheduling task, and the enabling parameter of the working template of the time domain symbol corresponding to the scheduling task is updated and configured to be enabled.
Further, in the embodiment of the present application, the configuration parameters of the scheduling task may be generated according to the received configuration message. The configuration parameters of the scheduling task are used for configuring the radio frequency chip in the target time slot to control the working state of the radio frequency interface, that is, the configuration parameters of the scheduling task can be used for link configuration.
For example, in the embodiment of the present application, the configuration parameter of the scheduling task may be at least one of the following parameters: hardware switch, power parameter, link parameter, frequency point parameter, filter bandwidth, path parameter and trigger time.
And 103, controlling the working state of the radio frequency front end according to the working template of one or more time domain symbols in the target time slot.
In the embodiment of the present application, after the working template of one or more time domain symbols in the target time slot is adjusted according to the scheduling task, the working state of the radio frequency front end can be further controlled according to the working template of one or more time domain symbols in the target time slot.
It can be understood that, in the embodiment of the present application, since the triggering time of the working template is determined by the corresponding time domain symbol, when the control of the working state of the radio frequency front end is implemented, the tasks of the corresponding working template may be directly triggered in sequence according to the sequence of the time domain symbols in the target time slot, so as to ensure that the scheduling tasks are processed according to the correct time sequence.
That is to say, in the embodiment of the present application, based on the working template corresponding to the pre-generated time domain symbol, after a new scheduling task is generated each time, different tasks do not need to be rearranged, but the tasks of the corresponding working template are triggered according to the sequence of the time domain symbol, so that the flow of task scheduling is simplified, and thus the control time is saved.
Further, the control method of the radio frequency front end provided in the embodiment of the present application may be applied to a control device or a terminal, where the control device or the terminal may be provided with a baseband chip and a radio frequency chip.
For example, in the present application, a terminal is taken as an example to describe a control method of a radio frequency front end. Fig. 7 is a schematic diagram of a first architecture for implementing a control method of a radio frequency front end, as shown in fig. 7, a baseband chip transmits data to be transmitted to a radio frequency chip, and the radio frequency chip transmits the data to the outside, thereby completing a data transmission process; the radio frequency chip receives data sent from the outside and then transmits the data to the baseband chip, thereby completing the data receiving process. The time slot for transmitting data is called a transmission time slot, namely the working time period for transmitting data by the radio frequency chip; the time slot for receiving data is called a receiving time slot, i.e. the working time period for receiving data by the radio frequency chip.
Specifically, in the present application, before the data transmission process is performed, the baseband chip starts the transmission phase-locked loop PLL, after the transmission PLL is stable, a Power Amplifier (PA) is turned on, and then parameter configuration is performed on a transmission circuit of the radio frequency chip, specifically, the baseband chip performs read/write operation on a relevant register on the radio frequency chip; before the data receiving process, a similar process is required, namely, the baseband chip starts the transmitting PLL and PA, and then the receiving circuit of the radio frequency chip is subjected to parameter configuration. Therefore, the communication between the baseband chip and the radio frequency chip includes the parameter configuration of the baseband chip to the radio frequency chip, that is, the data generated when the baseband chip performs read-write operation on the relevant register of the radio frequency chip, in addition to the data itself to be transmitted and received, so that the task configuration of data transmission in the time slot can be realized.
It can be understood that, in the present application, the radio frequency front end includes a radio frequency chip and a radio frequency control module in a baseband chip, and the configuration parameters in the configuration template include not only the configuration parameters of the radio frequency chip but also the configuration parameters of the radio frequency control module in the baseband chip.
Optionally, the control method for the radio frequency front end provided by the present application may be specifically applied to a baseband chip in the terminal, that is, may be applied to a parameter configuration process of the baseband chip to the radio frequency chip.
Further, in an embodiment of the present application, fig. 8 is a schematic diagram of an architecture for implementing a control method of a radio frequency front end, and as shown in fig. 8, a radio frequency control module may be disposed in a baseband chip in a terminal, where the radio frequency control module is configured to control the radio frequency chip. Accordingly, the terminal can complete the parameter configuration process of the baseband chip to the radio frequency chip through the radio frequency control module.
Fig. 9 is a schematic diagram illustrating an implementation flow of a control method of a radio frequency front end, as shown in fig. 9, in an embodiment of the present application, the method of controlling the radio frequency front end may include the following steps:
step 201, obtaining a configuration message at the current time slot, and generating a configuration parameter of a scheduling task corresponding to the target time slot according to the configuration message.
In the embodiment of the application, the terminal acquires the configuration message at the current time slot, and then can generate the configuration parameters of the scheduling task corresponding to the target time slot according to the configuration message.
It is understood that in the embodiments of the present application, the terminal may be various electronic devices having a communication function, including but not limited to mobile electronic devices such as a mobile phone, a notebook computer, a Digital broadcast receiver, a Personal Digital Assistant (PDA), a tablet computer (PAD), a Portable Multimedia Player (PMP), a vehicle-mounted electronic device (e.g., a car navigation electronic device), and the like, and fixed electronic devices such as a Digital Television (TV), a desktop computer, and the like.
It should be noted that, in the embodiment of the present application, the configuration message may be used to schedule data transmission of the target timeslot. The target time slot may be the current time slot or a time slot after the current time slot. For example, the terminal may receive a configuration message at time slot N (current time slot) for scheduling data transmission for time slot N (target time slot); alternatively, the terminal may receive a configuration message for scheduling data transmission of slot M (target slot) at slot N (current slot). Wherein N is an integer greater than 0, and M is an integer greater than N.
Further, in an embodiment of the present application, the configuration message may be a request message received by a radio frequency control module disposed in the terminal and used for requesting a configuration task.
It can be understood that, in the embodiment of the present application, after acquiring the configuration message at the current time slot, the terminal may generate the configuration parameter of the corresponding scheduling task according to the configuration message, where the configuration parameter of the scheduling task is used to configure the radio frequency chip at the target time slot, so that the radio frequency chip executes the scheduling task, that is, the configuration parameter of the scheduling task may perform link configuration.
Further, in this embodiment of the present application, before obtaining the configuration message at the current time slot and generating the configuration parameter of the scheduling task corresponding to the target time slot according to the configuration message, that is, before step 201, the method for controlling the radio frequency front end may further include the following steps:
step 205, determining the interface parameters and the scene parameters in the time slot before the target time slot.
And step 206, generating a working template corresponding to one or more time domain symbols in the target time slot according to the interface parameters and the scene parameters.
In the embodiment of the present application, the terminal may determine the interface parameter and the scene parameter in a time slot before the target time slot. And then generating a working template corresponding to one or more time domain symbols in the target time slot according to the interface parameters and the scene parameters.
Further, in the embodiment of the present application, when generating a working template corresponding to one or more time domain symbols in a target time slot according to an interface parameter and a scene parameter, a terminal may perform task configuration on the time domain symbols in the target time slot based on the interface parameter and the scene parameter, and determine an initial configuration parameter of an initial task corresponding to the time domain symbols; the enable parameter corresponding to the initial task may then be set to disable, so that a work template may be generated.
The initial task may be understood as a task corresponding to the target timeslot, where the task is predetermined by the terminal based on the interface parameter and the scene parameter.
Specifically, in the embodiment of the present application, after acquiring the interface parameter and the scene parameter, the terminal may perform task configuration processing on a part or all of the time domain symbols in the target time slot by using known information such as the interface parameter and the scene parameter, so as to determine an initial configuration parameter corresponding to an initial task corresponding to the part or all of the time domain symbols. The terminal may directly use some parameters in the interface parameters and the scene parameters as initial configuration parameters, and may also obtain the initial configuration parameters by calculation according to the interface parameters and the scene parameters.
Optionally, in this application, the initial configuration parameter is used to configure the radio frequency chip in the target timeslot, so that the radio frequency chip executes an initial task, that is, the initial configuration parameter may perform link configuration on the initial task. Wherein, the initial configuration parameter may be at least one of the following parameters: hardware switch, power parameter, link parameter, frequency point parameter, filter bandwidth, path parameter and trigger time.
Specifically, in the embodiment of the present application, the initial configuration parameter and the configuration parameter of the scheduling task may be non-coincident and non-conflicting configuration parameters. That is, the initial configuration parameter may be a part of configuration parameters for configuring the radio frequency front end, and the configuration parameter of the scheduling task may be another part of parameters for configuring the radio frequency front end.
It should be noted that, in the embodiment of the present application, each working template is provided with an enabling parameter based on the working template corresponding to the time domain symbol, where the enabling parameter may be used to indicate whether the radio frequency front end is enabled in the time domain symbol corresponding to the working template. For example, setting the value of the enabling parameter as a first value, that is, setting the enabling parameter as enabling, executing the corresponding task to enable the radio frequency front end; and setting the value of the enabling parameter as a second value, namely setting the enabling parameter as not-enabled, and then not executing the corresponding task, namely not enabling the radio frequency front end.
Alternatively, in this application, the first value may be 1 or true, and the second value may be 0 or false, which is not specifically limited in this application.
That is, in the embodiment of the present application, for each time domain symbol (e.g., symbol) in the target timeslot, the action of the rf switch may be considered to be the same, except that the trigger time of the switch is different, and the transmitted power (power) is different; therefore, the terminal can generate different working templates of different time domain symbols in advance in the time slot before the target time slot. Specifically, according to the interface parameter and the scene parameter of the current service, part of information, that is, initial configuration information, required by the configured radio frequency front end corresponding to any one time domain symbol may be obtained and/or calculated, and then the part of initial configuration information is added to the working template of the corresponding time domain symbol, and the enabling parameter of the working template is set to be disabled, thereby completing the generation of the working template.
For example, in the embodiment of the present application, fig. 10 is a schematic diagram of an operating template, and as shown in fig. 10, for 14 time domain symbols (e.g., symbol1 to symbol14) of a target timeslot, corresponding 14 operating templates are generated in advance, where initial values of enable parameters in the operating templates are all 0, that is, the enable parameters are not enabled; for different time domain symbols, the initial configuration information which is not completely the same is correspondingly written, for example, the power parameter corresponding to the time domain symbol 1(sym 1) is power P1, the power parameter corresponding to the time domain symbol 3(sym 3) is power P3, and the like; for the working template corresponding to each time domain symbol of the target timeslot, a transmission time parameter corresponding to the initial task, that is, a trigger time is set, for example, the trigger times of the initial tasks of the time domain symbol 0(sym 0) to the time domain symbol 13(sym 13) are T0 to T13, respectively.
Step 202, if the scheduling task conflicts with the scheduled task in the target time slot, updating and configuring the enabling parameters in the working template of the time domain symbol corresponding to the scheduled task as not to enable; and adding the scheduling task to the working template of the time domain symbol corresponding to the scheduling task according to the configuration parameters of the scheduling task, and updating and configuring the enabling parameters of the working template of the time domain symbol corresponding to the scheduling task into enabling.
And 203, if the scheduling task is not conflicted with the scheduled task in the target time slot or the scheduled task does not exist in the target time slot, adding the scheduling task to the working template of the time domain symbol corresponding to the scheduling task according to the configuration parameters of the scheduling task, and updating and configuring the enabling parameters of the working template of the time domain symbol corresponding to the scheduling task into enabling.
In the embodiment of the application, after the configuration message is acquired at the current time slot and the configuration parameters of the scheduling task corresponding to the target time slot are generated according to the configuration message, the terminal may adjust and update the working templates corresponding to the first or more time domain symbols in the target time slot by combining the current scheduling task according to whether the scheduled task exists in the target time slot.
It can be understood that, in the embodiment of the present application, the terminal needs to determine whether the target time slot has a scheduled task first, and if the target time slot has an earlier configured scheduled task, the terminal needs to further determine whether the scheduled task and the scheduled task conflict with each other, and further adjust the working template corresponding to the first time domain symbol or the plurality of time domain symbols in the target time slot according to the determination result.
Further, in the embodiment of the present application, if there is a scheduled task in the target time slot that conflicts with the scheduled task, it may be determined that the work template corresponding to the first one or more time domain symbols in the target time slot needs to be modified; and if the scheduled task which conflicts with the scheduled task does not exist in the target time slot or the scheduled task does not exist in the target time slot, determining that the scheduled task only needs to be added to the corresponding working template.
It should be noted that, in the embodiment of the present application, when a scheduled task conflicts with a scheduling task, it may be considered that the scheduling task is affected in the process of configuring the scheduling task, and therefore, a specific configuration parameter or an enabling parameter corresponding to the scheduled task needs to be modified in a work template.
Accordingly, in the present application, when there is no conflict between a scheduled task and a scheduling task, it may be considered that no impact is generated on any scheduled task in the process of scheduling task configuration, and therefore, it is not necessary to modify a specific configuration parameter or an enabling parameter corresponding to the scheduled task in a working template, and only the configuration parameter of the scheduled task needs to be added to the corresponding working template.
Accordingly, in the present application, when the scheduled task does not exist in the target timeslot, the terminal may add the configuration parameter of the scheduled task to the corresponding working template.
It should be noted that, in the present application, the terminal needs to determine whether the scheduled task exists in the target timeslot first. Specifically, when determining whether a scheduled task exists in a target time slot, if an enable parameter corresponding to a working template in the target time slot is enable, the terminal may determine that the scheduled task exists in the target time slot, and may determine that a task corresponding to the working template whose enable parameter is enable is the scheduled task of the target time slot; correspondingly, if the enabling parameters corresponding to the working template in the target time slot are all disabled, the terminal can determine that the scheduled task does not exist in the target time slot.
That is, in the present application, the terminal may also determine whether there is a scheduled task by using a working template corresponding to one or more time domain symbols in the generated target timeslot. Specifically, if an enable parameter in a working template corresponding to one or more time domain symbols in the target time slot is enabled, it may be determined that a scheduled task exists; if the enabling parameters in all the working templates corresponding to all the time domain symbols in the target time slot are not enabled, it can be determined that no scheduled task exists.
It should be noted that, in the embodiment of the present application, if a scheduled task in a target time slot conflicts with a scheduling task, in order to solve the problem of the conflict between the scheduled task and the scheduled task, a terminal may select, from a working template, to set an enable parameter of the working template of a time domain symbol corresponding to the scheduled task to be disabled; and then adding the scheduling task to the working template of the time domain symbol according to the configuration parameters of the scheduling task, and setting the enabling parameter of the time domain symbol corresponding to the scheduling task as enabling.
Therefore, in the present application, if a scheduled task conflicts with a scheduled task, the terminal needs to set an enable parameter corresponding to the scheduled task with the conflict to disable in a working template corresponding to the scheduled task, that is, control the scheduled task with the conflict not to be executed. And then storing the configuration parameters of the scheduling task to the corresponding work template to complete the addition of the scheduling task, and setting the enabling parameters corresponding to the scheduling task as enabling, namely controlling the scheduling task to be executed.
It should be noted that, in the embodiment of the present application, if the scheduling task does not conflict with the scheduled task in the target time slot, or the target time slot does not have the scheduled task, the terminal may select to directly add the scheduling task to the working template of the time domain symbol according to the configuration parameter of the scheduling task, and set the enabling parameter of the working template of the time domain symbol corresponding to the scheduling task as the enable.
It can be seen that, in the present application, if there is no scheduled task, or there is no conflict between the scheduled task and the scheduled task, the terminal does not need to modify the parameters in the working template of the time domain symbol corresponding to the scheduled task, but can directly store the configuration parameters of the scheduled task to the working template of the corresponding time domain symbol to complete the addition of the scheduled task, and at the same time, it needs to set the enabling parameters of the time domain symbol corresponding to the scheduled task as enabling, i.e. control the scheduled task to be executed.
It should be noted that, in the embodiment of the present application, when a terminal establishes a working template corresponding to one or more time domain symbols in a target time slot, the triggering time of the time domain symbol may be added to the corresponding working template, so that, based on different triggering times corresponding to different time domain symbols, the terminal may trigger different tasks according to the sequence of the triggering times through the working template, that is, the working template may be used to trigger the tasks according to a preset sequence. Wherein, the preset sequence is the sequence of the time domain symbols in the target time slot.
It can be understood that, in the embodiment of the present application, just as the working template may be used to trigger the tasks according to the preset sequence, after the task configuration is performed according to the acquired configuration message each time, the terminal does not need to repeatedly perform the task sequencing processing, thereby greatly reducing the complexity of the task configuration.
And step 204, controlling the working state of the radio frequency front end according to a preset sequence based on the working template of one or more time domain symbols in the target time slot.
In the embodiment of the present application, since the working templates may be used to trigger the tasks according to the preset sequence, the terminal may perform link configuration according to the corresponding preset sequence based on the working templates of one or more time domain symbols in the target time slot, so as to implement control over the working state of the radio frequency front end.
It should be noted that, in the embodiment of the present application, for a work template corresponding to any time domain symbol, a trigger time of a corresponding task may be set, so that after task configuration is completed for a target timeslot, a terminal may trigger different tasks according to the trigger time and an enable parameter corresponding to the different tasks based on the work template, and it is not necessary to repeat task sequencing after each task configuration process.
In summary, through the control method of the radio frequency front end proposed in the above steps 101 to 103 and 201 to 206, in the time slot before the target time slot, the terminal may perform the generation processing of the working template in advance for the target time slot, where the generation and addition of the initial configuration parameter of the initial task and the initialization of the enable parameter of the initial task are included, so that the task processing amount when the subsequent upper layer scheduling instruction arrives may be reduced, and the RF resource may be allocated at a finer time granularity.
It can be understood that, in the embodiment of the present application, based on a pre-generated working template of one or more time domain symbols in a target time slot, since corresponding initial configuration parameters have been generated according to known information (such as interface parameters, scene parameters, and the like), after a terminal acquires a configuration message, it only needs to generate other part of configuration parameters except the initial configuration parameters, and does not need to process all configuration parameters required by a device interface, thereby reducing the complexity of task configuration.
Further, in the embodiment of the present application, based on a pre-generated working template of one or more time domain symbols in a target time slot, after the terminal acquires a configuration message and generates a new task each time, when merging or adding the new task, it is not necessary to write the entire configuration information into the new task, but only write a new part of the configuration information; if the new configuration task conflicts with the scheduled task, the terminal does not need to delete the whole configuration information of the conflicting task, but only modifies the performance parameters of the conflicting task, and the complexity of task configuration is further reduced.
It can be understood that, in the embodiment of the present application, based on a pre-generated working template of one or more time domain symbols in a target time slot, after a terminal acquires a configuration message and generates a new task each time, it is no longer necessary to rearrange different tasks, but triggers the tasks according to the sequence of trigger times in the working template, which simplifies task scheduling, thereby saving execution time.
It should be noted that the control method for the radio frequency front end provided in the embodiment of the present application is a normalized process, and is not limited to an application scenario of radio frequency link configuration, nor to a baseband chip and a radio frequency chip, and is also applicable to other scenarios, devices, or modules. The unified scheduling strategy can be used for different scenes, and the complexity of SW is reduced.
The embodiment of the application provides a control method of a radio frequency front end, which determines a target time slot corresponding to a scheduling task; one or more time domain symbols in the target time slot are respectively configured with a working template; adjusting a working template of one or more time domain symbols in a target time slot according to a scheduling task; and controlling the working state of the radio frequency front end in the target time slot according to the working template of one or more time domain symbols. That is to say, in the embodiment of the present application, after a new scheduling task of a target time slot is generated based on a pre-generated working template of one or more time domain symbols in the target time slot, it is only necessary to update the corresponding working template according to configuration parameters of the scheduling task to implement addition processing of the new task and modification processing of the scheduled task that conflicts with the new task, that is, control of a working state of a radio frequency front end can be completed through the working template, and meanwhile, triggering of different tasks of the target time slot can be performed based on the sequence of the time domain symbols in the target time slot, and a process of sorting different tasks is omitted. Therefore, the method for controlling the radio frequency front end provided by the embodiment of the application greatly reduces the complexity of task configuration, shortens the time of task configuration, further realizes fast and efficient control processing of the radio frequency front end, and improves the communication performance.
Based on the above embodiments, in yet another embodiment of the present application, the control method of the radio frequency front end proposed by the present application is an active task scheduling manner, since each slot has 14 time domain symbols (symbols), each symbol may be a potential transmission start or a transmission end, and for each symbol, the action of the radio frequency switch is the same, except that the time of the switch is different, and the powers of the transmission are different; therefore, in the embodiment of the present application, for each slot, the terminal may pre-establish an RF switch template, that is, generate a corresponding working template for the time domain symbol, where the terminal may generate a corresponding working template for each symbol of the 14 symbols, or may generate at least one corresponding working template only for at least one symbol of the 14 symbols.
It is understood that in the embodiment of the present application, since each symbol is potentially transceiving, the difference between different symbols in transmitting is that the transmission time (i.e., trigger time) and transmission power may be different. The terminal may calculate the trigger time corresponding to each symbol in advance, and the transmission power may be calculated in advance, or may be calculated after receiving the trigger message or updated in real time.
Further, in the embodiment of the present application, based on a pre-generated working template corresponding to a time domain symbol in a target time slot, after acquiring configuration information, a terminal may generate a scheduling task of the target time slot according to the configuration information, and then update the working template based on a configuration parameter of the scheduling task, and specifically may send a symbol corresponding to an enable or disable working template, thereby implementing fast configuration of the scheduling task.
That is to say, in the embodiment of the present application, the terminal may perform preparation work on each symbol in the target timeslot in advance, and establish a corresponding work template, so that after the configuration message of L1C is obtained, only the tasks of the symbols corresponding to the configuration parameters enable/disable of the scheduling task generated according to the configuration information are needed, and thus the configuration time can be greatly saved.
Fig. 11 is a schematic flow chart illustrating a third implementation flow of a control method of a radio frequency front end, as shown in fig. 11, in an embodiment of the present application, the method of controlling the radio frequency front end may include the following steps:
step 301, determining an initial configuration parameter corresponding to the time domain symbol in the target time slot according to the interface parameter and the scene parameter.
In the embodiment of the application, the terminal may select, in a time slot before the target time slot, an initial configuration parameter corresponding to a time domain symbol in the target time slot according to the interface parameter and the scene parameter. The initial configuration parameters may be used to configure the radio frequency chip in the target timeslot, so that the radio frequency chip executes an initial task, that is, the initial configuration parameters may perform link configuration on the initial task.
Optionally, in this application, based on the interface parameter and the scene parameter, the terminal may select to perform initial configuration parameter determination on part or all of the time domain symbols in the target time slot. Wherein one time domain symbol corresponds to a set of initial configuration parameters.
And step 302, generating a working template corresponding to the time domain symbol in the target time slot according to the initial configuration parameters.
In the embodiment of the application, after determining the initial configuration parameters corresponding to the time domain symbols in the target time slot according to the interface parameters and the scene parameters, the terminal may generate the working template corresponding to the time domain symbols in the target time slot according to the initial configuration parameters. The work template is used for triggering tasks according to a preset sequence.
Optionally, in an embodiment of the present application, after the terminal completes generation of the initial configuration parameter, the terminal may write the initial configuration parameter corresponding to a certain time domain symbol into the working template corresponding to the time domain symbol, and set the enabling parameter corresponding to the working template to be disabled, thereby completing generation of the working template corresponding to the time domain symbol. Wherein the enabling parameter may be used to indicate whether to perform the task.
Step 303, receiving the first configuration message in the first time slot, and generating a first configuration parameter corresponding to the first task according to the first configuration message.
In an embodiment of the present application, after generating a working template corresponding to a time domain symbol in a target time slot according to an initial configuration parameter, a terminal may receive a first configuration message in a first time slot, and then may generate a first configuration parameter corresponding to a first task according to the first configuration message. The first time slot may be a time slot before the target time slot, or may be the target time slot.
It should be noted that, in the embodiment of the present application, the first configuration parameter is used to configure the radio frequency chip in the target timeslot, so that the radio frequency chip executes the scheduling task, that is, the first configuration parameter may perform link configuration on the scheduling task. The first configuration parameter and the initial configuration parameter may be non-coincident and non-conflicting configuration parameters. That is, the initial configuration parameter may be a part of parameters for configuring the rf chip, and the first configuration parameter may be another part of parameters for configuring the rf chip.
Step 304, adding a first task to the work template according to the first configuration parameter.
In an embodiment of the application, after the terminal receives the first configuration message in the first time slot and generates the first configuration parameter corresponding to the first task according to the first configuration message, the first task may be added to the working template according to the first configuration parameter.
It should be noted that, in the embodiment of the present application, because the first configuration message may be a first configuration message acquired after the terminal generates the working template, at this time, no scheduled task exists in the working template corresponding to one or more time domain symbols in the target time slot, that is, it may be considered that no scheduled task that conflicts with the first task exists in the target time slot, the terminal may directly write the first configuration parameter into the corresponding working template, and set the enable parameter corresponding to the first task in the working template as enable, thereby completing the addition processing of the first task.
And 305, receiving a second configuration message at a second time slot, and generating a second configuration parameter corresponding to the second task according to the second configuration message.
In an embodiment of the present application, after the first task is added to the working template according to the first configuration parameter, the terminal may receive a second configuration message at the second time slot, and then may generate a second configuration parameter corresponding to the second task according to the second configuration message. The second time slot may be a time slot before the target time slot, or may be the target time slot.
It should be noted that, in the embodiment of the present application, the second configuration parameter is used to configure the radio frequency chip in the target timeslot, so that the radio frequency chip executes the scheduling task, that is, the second configuration parameter may perform link configuration on the scheduling task. The second configuration parameter and the initial configuration parameter may be non-coincident and non-conflicting configuration parameters. That is, the initial configuration parameter may be a part of parameters for configuring the rf chip, and the first configuration parameter may be another part of parameters for configuring the rf chip.
And step 306, if the first task conflicts with the second task, deleting the first task from the working template, and adding the second task to the working template according to the second configuration parameter.
In the embodiment of the present application, after the terminal receives the second configuration message at the second time slot and generates the second configuration parameter corresponding to the second task according to the second configuration message, it needs to first determine whether a scheduled task (the first task) of the target time slot conflicts with the second task, and if the first task conflicts with the second task, the terminal needs to delete the first task in the preset template, and then add the second task to the working template according to the second configuration parameter.
It should be noted that, in the embodiment of the present application, because the second configuration message is not the first configuration message acquired after the terminal generates the work template, at this time, a scheduled task exists in the work template corresponding to one or more time domain symbols in the target time slot, the terminal needs to first determine whether the scheduled task in the target time slot conflicts with the second task, that is, determine whether the first task conflicts with the second task, if the first task conflicts with the second task, the terminal needs to delete the first task by setting the enable parameter corresponding to the first task in the work template to be disabled, then write the second configuration parameter into the corresponding work template, and simultaneously set the enable parameter corresponding to the second task in the work template to be enabled, thereby completing the addition processing of the second task.
And 307, if the first task is not conflicted with the second task, adding the second task to the working template according to the second configuration parameter.
In the embodiment of the present application, after the terminal receives the second configuration message at the second time slot and generates the second configuration parameter corresponding to the second task according to the second configuration message, it needs to first determine whether the scheduled task (the first task) of the target time slot conflicts with the second task, if the first task does not conflict with the second task, the terminal may directly write the second configuration parameter into the corresponding work template, and simultaneously set the enable parameter corresponding to the second task in the work template as the enable, thereby completing the addition processing of the second task.
And 308, triggering tasks according to a preset sequence based on the working template corresponding to the time domain symbol in the target time slot.
In the embodiment of the application, the terminal may trigger the tasks according to a preset sequence after completing addition or modification of different tasks according to different configuration messages based on a working template corresponding to one or more time domain symbols in a target time slot. The set sequence is the sequence of the trigger times corresponding to different time domain symbols in the target time slot.
In summary, according to the control method of the radio frequency front end proposed in the above steps 301 to 308, since each time domain symbol (symbol) in each timeslot may have a configuration requirement, the terminal may calculate or directly obtain initial configuration information according to a device interface format (interface parameter) and a current service scenario (scene parameter), and then write the initial configuration information into a corresponding working template, that is, configure an initial task in each working template, so as to implement the preset of the working template corresponding to each time domain symbol in a target timeslot (next slot), for example, pre-generate 14 working templates corresponding to 14 symbols in the target timeslot, where each working template may determine the configuration requirement of the corresponding symbol.
Further, in the embodiment of the present application, for each task corresponding to each time domain symbol, a status flag (enabling parameter) may be set in the work template to indicate whether the corresponding task will be sent to the hardware. When the work template is generated, the initial state corresponding to the initial task is set to be disabled, namely the initial task is not executed.
It should be noted that, in the embodiment of the present application, the configuration time (trigger time) of each working template corresponding to each time domain symbol may be calculated and set in advance, and based on the sequence of the multiple trigger times corresponding to the multiple working templates, the corresponding preset sequence for triggering different tasks may be determined.
It can be understood that, in the embodiment of the present application, after the terminal acquires the configuration message each time, only the calculation of the configuration parameters of the other parts except the initial configuration parameters is performed on the target timeslot according to the configuration message, and it is not necessary to repeatedly determine the initial configuration parameters that have been obtained in advance. Meanwhile, if the scheduled task exists in the target time slot, the terminal can judge whether the scheduled task in the target time slot conflicts with the scheduled task, determine a corresponding task configuration type (such as task modification or task addition) according to a judgment result, and update part of parameters in the working template according to the configuration parameters based on the task configuration type, so that the rapid configuration of the task can be realized.
The embodiment of the application provides a control method of a radio frequency front end, which determines a target time slot corresponding to a scheduling task; one or more time domain symbols in the target time slot are respectively configured with a working template; adjusting a working template of one or more time domain symbols in a target time slot according to a scheduling task; and controlling the working state of the radio frequency front end in the target time slot according to the working template of one or more time domain symbols. That is to say, in the embodiment of the present application, after a new scheduling task of a target time slot is generated based on a pre-generated working template of one or more time domain symbols in the target time slot, it is only necessary to update the corresponding working template according to configuration parameters of the scheduling task to implement addition processing of the new task and modification processing of the scheduled task that conflicts with the new task, that is, control of a working state of a radio frequency front end can be completed through the working template, and meanwhile, triggering of different tasks of the target time slot can be performed based on the sequence of the time domain symbols in the target time slot, and a process of sorting different tasks is omitted. Therefore, the method for controlling the radio frequency front end provided by the embodiment of the application greatly reduces the complexity of task configuration, shortens the time of task configuration, further realizes fast and efficient control processing of the radio frequency front end, and improves the communication performance.
