Description
Technical Field
The present invention relates to the field of information processing technologies, and in particular, to a calibration method, a network device, a terminal device, and a computer-readable storage medium.
Background
The millimeter wave phase allows for power savings and receiver type changes, requiring calibration of Power Amplification (PA) as well as Local Oscillation (LO) and real imaginary part (IQ) image, etc. There are two calibration targets that are currently generally recognized in the standard discussion process as follows: PA power calibration, LO (local oscillator)/IQ image calibration.
For the two calibration targets mentioned above, two types of calibration are proposed in the standard discussion:
rank restore gap (RRG, rank limit calibration interval): in the MIMO transmission, only one (layer) of the streams is transmitted (rank 1 transmission one TX chain); the other transmit chain is used for calibration, i.e. 2TX to 1TX, the calibration type being mainly used for PA power calibration
Total gap (TG, total calibration interval): in the gap interval of calibration, the terminal does not transmit and receive at all, only carries out calibration, does not need to start PA, only carries out internal calibration; including periodic calibration (1 slot/s) + event-triggered calibration (e.g., excessive power, BW change, etc.), this type of calibration is mainly used for LO/IQ image calibration
However, for TG, the definition of IQ real part and imaginary part, and LO local oscillation calibration time pattern, performed by the UE is currently lacking; for RRG, when a UE needs to turn on PA when performing PA calibration on a certain link, there is a certain transmit power, which may cause large interference to other UE transmissions.

Detailed Description
Technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 1, an embodiment of the present invention provides a calibration method, which is applied to a terminal device, and the method includes:
step 11: receiving calibration interval configuration information configured by network equipment, wherein the calibration interval configuration information at least comprises a calibration type;
step 12: determining calibration time resources based at least on a calibration type in the calibration interval configuration information;
step 13: and performing calibration processing corresponding to the calibration type based on the calibration time resource.
The calibration interval configuration information is a subset of the DRX configuration information.
It should be understood that, in the scheme described in the above steps, the terminal device may select the corresponding time resource by itself. Further, the corresponding time resource can be determined according to the relevant information configured by the network device.
Specifically, calibration interval configuration information configured on a network side is received, wherein the calibration interval configuration information at least comprises a calibration type and at least one calibration parameter corresponding to the calibration type;
and selecting a target calibration type and a corresponding time resource based on the calibration type and the corresponding calibration parameter in the calibration interval configuration information configured by the network side.
The calibration interval configuration information sent by the network device may be a DRX configuration subset, which may include a calibration type, a calibration period, a time offset, a calibration length, a trigger event, and the like.
The selecting a target calibration type and a time resource corresponding to the target calibration type based on the calibration type and the calibration parameter corresponding to the calibration type in the calibration interval configuration information configured on the network side can be understood as how long the terminal device determines in which manner to perform calibration according to the calibration interval configuration information on the network side, for example, see the following situations:
the method comprises the following steps that 1, network side calibration interval configuration information indicates that the calibration type of a terminal is a TG (total gap) type, a periodic calibration is carried out, a calibration period is 1s, a time offset is 1slot, a calibration length is 1 symbol, and no trigger event information exists; then the terminal device starts RRG calibration with 1s as a period at 1slot (time offset) after receiving the calibration interval configuration information, and calibrates 1 symbol in length.
Case 2, the network side calibration interval configuration information indicates that the calibration type of the terminal device is a TG (total gap) type, no period information, a time offset of 1slot, a calibration length of 1 symbol, and a trigger event is that the output power reaches 23dBm; the terminal starts TG power calibration based on a trigger event at 1slot (time offset) after receiving the calibration interval configuration information, and initiates calibration work in units of 1 symbol if PA transmit power is equal to 23 dBm.
Case 3, the network side calibration interval configuration information indicates that the calibration type of the terminal is an RRG (rank correct gap) type, the period calibration is performed with a calibration period of 1s, a time offset of 1slot, a calibration length of 1 symbol, and no trigger event information; the terminal determines that 1slot (time offset) after receiving the calibration interval configuration information starts RRG calibration with 1s as a period, and calibrates 1 symbol in length.
Case 4, the network side calibration interval configuration information indicates that the calibration type of the terminal is an RRG (total gap) type, no period information, a time offset of 1slot, a calibration length of 1 symbol, and a trigger event is that the output power reaches 23dBm; the terminal starts RRG power calibration based on a trigger event at 1slot (time offset) after receiving the calibration interval configuration information, and initiates calibration work in units of 1 symbol if the PA transmit power is equal to 23 dBm.
It should be understood that the foregoing is only an example, and other settings of time offset, calibration type, trigger event, etc. may exist, which are not exhaustive in the present embodiment.
Further, the calibration interval configuration information further includes calibration parameters;
the calibration parameters include at least one of:
calibration period, calibration time offset, calibration time length, calibration accuracy, calibration trigger event, corresponding calibration type.
The calibration time resource includes at least one of:
measurement interval, partial or specific time in DRX or CDRX, GP within a specific subframe, interrupt time resource.
The interrupt time resource comprises one of:
a transition duration between DRX activation and deactivation or its time-length subset;
a non-DRX to DRX transition duration or its time-length subset;
the switching duration between the addition and deletion of the Scell or its time-length subset;
a transition duration between activation and deactivation of the Scell or its timespan;
the duration of the measurement of the SCC or its time-long subset;
the uplink UL carrier radio resource controls the duration of RRC reconfiguration or the time length subset thereof;

The calibration type includes one of:

The calibrating the target calibration type based on the time resource includes:
selecting a first time window before signal transmission based on the calibration time resource; wherein the first time window is all or part of the time length from power-off to power-on;
and calibrating the target calibration type based on the selected first time window.
Wherein the content of the first and second substances,
the performing calibration processing corresponding to the calibration type based on the calibration time resource further includes:
determining a time at which power is turned on and a second time window before signal transmission based on the calibration time resource; wherein the second time window is all or part of the time length from power off to power on; the length of the second time window is greater than that of the first time window; the moment of turning on the power is earlier than the moment of the originally determined turning on power;
calibrating the target calibration type based on the selected second time window
Specifically, the calibration type may be TG or RRG, and the specific processing flow may include:
for RRG calibration (but of course also for TG calibration), the terminal autonomously selects a time window before sending the signal for calibration; the selection of the time window may be determined according to the time resource, for example, if it is determined that the duration between the times 1-2 may be calibrated according to the measurement interval, the time window between the signals is selected between the times 1-2 to be calibrated; alternatively, the time window between the transmitted signals may be selected for calibration when the occurrence of a triggering event is detected.
Wherein the time window is all or part of the time length from power off to power on; specifically, all or a portion of the time in the transition time between power OFF to power ON. For example, the total time refers to the time when the terminal device uses the total transition time to perform PA calibration; the partial time refers to power calibration performed during the remaining time after the UE completes the power ramp-up from OFF to ON before the specified time.
It should be further noted that, the PA calibration is performed at all times of the time window, and may be performed after the power ramp-up is completed in the transition period, where the ramp-up time + the power calibration time and the total time less than or equal to the time window, that is, the power transition time, are performed.
For another example, the time other than the transition time from power OFF to power ON may be an ON procedure initiated in advance for the terminal, that is, the transition start time from OFF to ON is advanced, and after the power boost is completed, the UE performs power calibration in the remaining time.
The calibration process may be: when the UE works in a training working mode of DPD calibration in calibration, the chip related calibration circuit performs successive measurement and successive approximation step by step, and finally an inverse function close to a transmission path PA complex gain curve can be obtained, namely, compensation coefficients corresponding to different amplitudes are obtained and recorded in a compensation coefficient table.
Specifically, for TG calibration, when UE works in a calibration training working mode in a calibration time window, a chip-related calibration circuit calibrates DC Offset and IQ impedance of a receiving channel first, and then calibrates DC Offset and IQimpedance of a transmitting channel; and step-by-step successive measurement and successive approximation are carried out, and finally an inverse function close to a complex gain curve of a transmitting path (mainly PA) can be obtained and recorded in a compensation coefficient table.
Calibrating the RRG, wherein when the UE works in a calibrated training working mode in a calibration time window, a chip related calibration circuit firstly calibrates the transmitting power of a receiving access and then calibrates the transmitting power of a transmitting access; and step-by-step successive measurement and successive approximation are carried out, and finally an inverse function close to a complex gain curve of a transmitting path (mainly PA) can be obtained and recorded in a compensation coefficient table.
Wherein, the DPD is described in detail as follows:
calibrating DC Offset and IQ imbalance im balance of a receiving path by a chip related calibration circuit, calibrating DC Offset and IQ imbalance im balance of a transmitting path, generating a complex source waveform series by tracking _ gen, and acquiring initial complex gain to update to a DPD compensation Table (LUT, look Up Table); generating a first step signal (each step is a direct current or single-tone waveform) by Training _ gen to obtain a first complex response of the whole loop to the step signal, calculating a corresponding complex gain correction value through a difference value of the signal after the complex gain compensation and the response signal, and updating the complex gain correction value into a DPD LUT table; continuing to generate a second step signal from Training _ gen, similarly obtaining a second complex response, and updating the LUT table; and step-by-step successive measurement and successive approximation are carried out, and finally an inverse function close to a complex gain curve of a transmitting path (mainly PA) can be obtained and recorded in a compensation coefficient table, namely an LUT table.
The method further comprises the following steps: after calibration is completed, in a sending working mode, determining a transmission signal amplitude and a phase compensation coefficient through a compensation coefficient table obtained through calibration, carrying out complex multiplication to obtain a modulation waveform after DPD processing, and transmitting the modulation waveform through an antenna; the compensation coefficient table contains different signal amplitudes and different object relations between phase compensation coefficients.
That is, after the terminal device completes calibration in the selected time window, when the terminal device transmits the operating mode, the LUT table is used to find out the amplitude and phase compensation coefficient of the transmitted signal, and complex multiplication is performed to obtain the modulation waveform after DPD processing, and the modulation waveform is radiated by the antenna.
According to the RAN4 standardization conclusion, the influence of the transmission signal ON the system in the OFF-ON transition time can be ignored, so that the influence of the transmission interference ON the system in the PA calibration stage can be effectively reduced.
Still further, the scheme provided by the present embodiment is explained with reference to fig. 2: the network equipment sends information such as cycle, time deviation, calibration length, calibration type and the like to the terminal equipment through the DRX configuration information subset; then, the terminal device may periodically perform calibration work of a corresponding type at a corresponding time unknown according to the configuration information or according to an event triggering principle.
If the network side does not configure the calibration related information or the configured calibration related information does not meet the requirements, the terminal can autonomously select time to carry out power calibration; the time resources selected by the method can comprise: measurement Gap, DRX, special subframe GP, interrupt time, etc.
Fig. 3 is a schematic diagram showing a cycle of the calibration process based on the configured cycle in the present embodiment.
With respect to the aforementioned duration of power ramp-up, refer to fig. 4, which shows that the power ramp-up process has a duration, and the time window of this embodiment may be all or part of the duration (10 us).
Examples 1A,
Referring to fig. 5, the transition time for nr terminal OFF-ON is 10us, assuming that 8us is needed for UE PA calibration. If the NR terminal can complete power ramp-up within 2us, i.e. from OFF to ON, the terminal can use the remaining 8us for PA calibration, i.e. the remaining 8us is TG time.
Examples 2,
Referring to fig. 6, the OFF-ON transition time of the nr terminal is 10us, and assuming that 8us is needed for PA calibration of the UE, if the terminal can perform PA calibration at least 8us earlier, PA calibration can be performed after the OFF-ON power ramp-up is completed.
Examples 3,
If the network side configures the calibration type TG, the calibration period 1s, the calibration length 1slot and the time offset 2slot in the DRX subset, after receiving the corresponding DRX calibration subset, the UE starts PA calibration at 2slot after receiving the configuration information, calibrates the length 1slot and periodically performs the calibration with 1s as a time unit.
Examples 5,
The terminal may choose to perform PA calibration within a specified time, such as but not limited to a measurement gap (measurement gap), DRX, GP (guard period) within a special subframe, interrupt time resource, etc.
It can be seen that, by adopting the above scheme, the target calibration type can be calibrated based on the selected time resources, where the time resources may include a measurement interval (measurement gap), DRX, GP within a special subframe, an interruption time resource, and the like. In this way, an accurate calibration time pattern can be determined, and since the calibration can be performed in the interrupt time resource, interference of the calibration process with other terminal devices can be reduced.
As shown in fig. 7, an embodiment of the present invention further provides a calibration method, applied to a terminal device, including:
step 21: the terminal equipment determines a calibration type and a calibration time resource corresponding to the calibration type;
step 22: and performing calibration processing corresponding to the calibration type based on the calibration time resource.
The difference from the previous embodiment is that in this embodiment, the terminal device determines the calibration type and the calibration time resource corresponding to the calibration type, and then performs calibration processing on the calibration type based on the calibration time resource.
That is to say, the terminal device can autonomously select a time resource for calibration according to calibration interval configuration information, where the calibration interval configuration information further includes calibration parameters;
the calibration parameters include at least one of:
calibration period, calibration time offset, calibration time length, calibration accuracy, calibration trigger event, corresponding calibration type.
The calibration time resource includes at least one of:
measurement interval, DRX or fractional time or specific time in CDRX, GP within a specific subframe, interrupt time resource.
The interrupt time resource comprises one of:
a transition duration between DRX activation and deactivation or its time-length subset;
a non-DRX to DRX transition duration or its time-length subset;
the switching time length between the addition and the deletion of the Scell or the time length subset thereof;
the transition duration between activation and deactivation of the Scell or its time-long subset;
the duration of the measurement of the SCC or its time-long subset;
the uplink UL carrier radio resource controls the duration of RRC reconfiguration or the time length subset thereof;
the transition duration of BWP or its long subset is activated.
The calibration type includes one of:
power amplifier power calibration, local oscillator calibration and IQ mirror calibration.
The calibrating the target calibration type based on the time resource includes:
selecting a first time window before signal transmission based on the calibration time resource; wherein the first time window is all or part of the time length from power-off to power-on;
and calibrating the target calibration type based on the selected first time window.
Wherein the content of the first and second substances,
the performing calibration processing corresponding to the calibration type based on the calibration time resource further includes:
determining a time at which power is turned on and a second time window before signal transmission based on the calibration time resource; wherein the second time window is all or part of the time length from power off to power on; the length of the second time window is greater than that of the first time window; the moment of turning on the power is earlier than the moment of the originally determined turning on power;
calibrating the target calibration type based on the selected second time window
Specifically, the foregoing calibration type may be TG or RRG calibration, and a specific processing flow may include:
for RRG calibration (but certainly also for TG calibration), the terminal autonomously selects a time window before sending the signal for calibration; the selection of the time window may be determined according to the time resource, for example, if it is determined that the duration between the times 1-2 may be calibrated according to the measurement interval, the time window between the signals is selected between the times 1-2 to be calibrated; alternatively, the time window between the transmitted signals may be selected for calibration when the occurrence of a triggering event is detected.
Wherein the time window is all or part of the time length from power off to power on; specifically, all or a portion of the time in the transition time between power OFF to power ON. For example, the total time refers to the time when the terminal device uses the total transition time to perform PA calibration; the partial time refers to power calibration performed during the remaining time after the UE completes the power ramp-up from OFF to ON before the specified time.
It should be further noted that, the PA calibration is performed at all times of the time window, and may be performed after the power ramp-up is completed in the transition period, where the ramp-up time + the power calibration time and the total time less than or equal to the time window, that is, the power transition time, are performed.
For another example, the time other than the transition time from power OFF to power ON may be an ON flow initiated in advance for the terminal, that is, the transition start time from OFF to ON is advanced, and after the power boost is completed, the UE performs power calibration in the remaining time.
The calibration process may be: when the UE works in a training working mode of DPD calibration in calibration, the chip related calibration circuit performs successive measurement and successive approximation step by step, and finally an inverse function close to a transmission path PA complex gain curve can be obtained, namely, compensation coefficients corresponding to different amplitudes are obtained and recorded in a compensation coefficient table.
Specifically, for TG calibration, when UE works in a calibration training working mode in a calibration time window, a chip-related calibration circuit calibrates DC Offset and IQ impedance of a receiving channel first, and then calibrates DC Offset and IQimpedance of a transmitting channel; and step-by-step successive measurement and successive approximation are carried out, and finally an inverse function close to a complex gain curve of a transmitting path (mainly PA) can be obtained and recorded in a compensation coefficient table.
Calibrating the RRG, wherein when the UE works in a calibrated training working mode in a calibration time window, a chip related calibration circuit calibrates the transmitting power of a receiving access first and then calibrates the transmitting power of a transmitting access; and step-by-step successive measurement and successive approximation are carried out, and finally an inverse function close to a complex gain curve of a transmitting path (mainly PA) can be obtained and recorded in a compensation coefficient table.
The method further comprises the following steps: after calibration is completed, in a sending working mode, determining a transmission signal amplitude and a phase compensation coefficient through a compensation coefficient table obtained through calibration, carrying out complex multiplication to obtain a modulation waveform after DPD processing, and transmitting the modulation waveform through an antenna; the compensation coefficient table contains different signal amplitudes and different object relations between phase compensation coefficients.
That is, after the terminal device completes calibration in the selected time window, when the terminal device transmits the operating mode, the LUT table is used to find out the amplitude and phase compensation coefficient of the transmitted signal, and complex multiplication is performed to obtain the modulation waveform after DPD processing, and the modulation waveform is radiated by the antenna.
According to the RAN4 standardization conclusion, the influence of the transmission signal ON the system in the OFF-ON transition time can be ignored, so that the influence of the transmission interference ON the system in the PA calibration stage can be effectively reduced.
If the network side does not configure the calibration related information or the configured calibration related information does not meet the requirements, the terminal can autonomously select time to carry out power calibration; the time resources selected by the method can comprise: measurement Gap, DRX, special subframe GP, interrupt time, etc.
Fig. 3 is a schematic diagram showing a cycle of the calibration process performed based on the configured cycle in the present embodiment.
With respect to the aforementioned power-up duration, refer to fig. 4, which shows that the power-up process has a duration, and the time window of this embodiment may be all or part of the duration (10 us).
Examples 1, 1,
Referring to fig. 5, the transition time for the nr terminal OFF-ON is 10us, assuming that 8us is required for UE PA calibration. If the NR terminal can complete power ramp-up within 2us, i.e. from OFF to ON, the terminal can use the remaining 8us for PA calibration, i.e. the remaining 8us is TG time.
Examples 2,
Referring to fig. 6, the OFF-ON transition time of the nr terminal is 10us, and assuming that 8us is needed for PA calibration of the UE, if the terminal can perform PA calibration at least 8us earlier, PA calibration can be performed after the OFF-ON power ramp-up is completed.
Examples 3,
If the calibration type is TG, the calibration period is 1s, the calibration length is 1slot and the time offset is 2 slots in the DRX subset, after the UE receives the corresponding DRX calibration subset, PA calibration is started at 2 slots after the UE receives the configuration information, the calibration length is 1slot, and the period is carried out by taking 1s as a time unit.
Examples 5,
The terminal may choose to perform PA calibration within a specified time, such as but not limited to a measurement gap (measurement gap), DRX, GP (guard period) within a special subframe, interrupt time resource, etc.
It can be seen that, by adopting the above scheme, the target calibration type can be calibrated based on the selected time resources, where the time resources may include a measurement interval (measurement gap), DRX, GP within a special subframe, an interruption time resource, and the like. In this way, an accurate calibration time pattern can be determined, and since the calibration can be performed in the interrupt time resource, interference of the calibration process with other terminal devices can be reduced.
As shown in fig. 8, an embodiment of the present invention provides a calibration method applied to a network device, where the method includes:
step 31: and configuring calibration interval configuration information for the terminal equipment, wherein the calibration interval configuration information at least comprises a calibration type.
The calibration interval configuration information is a subset of DRX configuration information.
It should be understood that, in the scheme described in the above steps, the terminal device may select the corresponding time resource by itself. Further, the corresponding time resource can be determined according to the relevant information configured by the network device.
The calibration interval configuration information of the network device may be a DRX configuration subset, which may include a calibration type, a calibration period, a time offset, a calibration length, a trigger event, and the like.
The selecting a target calibration type and a time resource corresponding to the target calibration type based on the calibration type and the calibration parameter corresponding to the calibration type in the calibration interval configuration information configured on the network side can be understood as how long the terminal device determines in which manner to perform calibration according to the calibration interval configuration information on the network side, for example, see the following situations:
in case 1, the network side calibration interval configuration information indicates that the calibration type of the terminal is a TG (total gap) type, the period calibration is performed with a calibration period of 1s, the time offset is 1slot, the calibration length is 1 symbol, and no trigger event information exists; the terminal device starts RRG calibration with a period of 1s at 1slot (time offset) after receiving the calibration interval configuration information, and calibrates 1 symbol in length.
Case 2, the network side calibration interval configuration information indicates that the calibration type of the terminal device is a TG (total gap) type, no period information, a time offset of 1slot, a calibration length of 1 symbol, and a trigger event is that the output power reaches 23dBm; the terminal starts TG power calibration based on a trigger event at 1slot (time offset) after receiving the calibration interval configuration information, and initiates calibration work in units of 1 symbol if PA transmit power is equal to 23 dBm.
Case 3, the network side calibration interval configuration information indicates that the calibration type of the terminal is an RRG (rank correct gap) type, the period calibration is performed with a calibration period of 1s, a time offset of 1slot, a calibration length of 1 symbol, and no trigger event information; the terminal determines that 1slot (time offset) after receiving the calibration interval configuration information starts to perform RRG calibration with 1s as a period, and the calibration length is 1 symbol.
Case 4, the network side calibration interval configuration information indicates that the calibration type of the terminal is an RRG (total gap) type, no period information, a time offset of 1slot, a calibration length of 1 symbol, and a trigger event is that the output power reaches 23dBm; the terminal starts RRG power calibration based on a trigger event at 1slot (time offset) after receiving the calibration interval configuration information, and initiates calibration work in units of 1 symbol if the PA transmit power is equal to 23 dBm.
It should be understood that the foregoing is only an example, and other settings of time offset, calibration type, trigger event, etc. may exist, which are not exhaustive in the present embodiment. In addition, the specific contents of the calibration interval configuration information and other parameters in this embodiment are the same as those in the foregoing embodiment, and are not described again here.
It should be noted that the network device does not schedule data transmission to the terminal during the calibration interval. That is, when determining some calibration intervals, the network device may not schedule data transmission to the terminal, so as to avoid the problem that data cannot be transmitted correctly.
It can be seen that, by adopting the above scheme, the target calibration type can be calibrated based on the selected time resources, where the time resources may include a measurement interval (measurement gap), DRX, GP within a special subframe, an interruption time resource, and the like. In this way, an accurate calibration time pattern can be determined, and since the calibration can be performed in the interrupt time resource, interference of the calibration process with other terminal devices can be reduced.
As shown in fig. 9, an embodiment of the present invention provides a terminal device, including:
a first communication interface 41, configured to receive calibration interval configuration information configured by a network device, where the calibration interval configuration information at least includes a calibration type;
a first processing unit 42, which determines a calibration time resource at least based on the calibration type in the calibration interval configuration information; and performing calibration processing corresponding to the calibration type based on the calibration time resource.
It should be understood that, in the scheme described in the above steps, the terminal device may select the corresponding time resource by itself. Further, the corresponding time resource can be determined according to the relevant information configured by the network device.
Specifically, the first communication interface 41 receives calibration interval configuration information configured on the network side, where the calibration interval configuration information at least includes a calibration type and at least one calibration parameter corresponding to the calibration type;
the first processing unit 42 selects and selects a target calibration type and a time resource corresponding to the target calibration type based on the calibration type and the calibration parameter corresponding to the calibration type in the calibration interval configuration information configured on the network side.
The calibration interval configuration information sent by the network device may be a DRX configuration subset, which may include a calibration type, a calibration period, a time offset, a calibration length, a trigger event, and the like.
The selecting a target calibration type and a time resource corresponding to the target calibration type based on the calibration type and the calibration parameter corresponding to the calibration type in the calibration interval configuration information configured on the network side can be understood as how long the terminal device determines in which manner to perform calibration according to the calibration interval configuration information on the network side, for example, see the following situations:
the method comprises the following steps that 1, network side calibration interval configuration information indicates that the calibration type of a terminal is a TG (total gap) type, a periodic calibration is carried out, a calibration period is 1s, a time offset is 1slot, a calibration length is 1 symbol, and no trigger event information exists; the terminal device starts RRG calibration with a period of 1s at 1slot (time offset) after receiving the calibration interval configuration information, and calibrates 1 symbol in length.
Case 2, the network side calibration interval configuration information indicates that the calibration type of the terminal device is a TG (total gap) type, no period information, a time offset of 1slot, a calibration length of 1 symbol, and a trigger event is that the output power reaches 23dBm; the terminal starts TG power calibration based on a trigger event at 1slot (time offset) after receiving the calibration interval configuration information, and initiates calibration work in units of 1 symbol if PA transmit power is equal to 23 dBm.
Case 3, the network side calibration interval configuration information indicates that the calibration type of the terminal is an RRG (rank correct gap) type, the period calibration and calibration period is 1s, the time offset is 1slot, the calibration length is 1 symbol, and there is no trigger event information; the terminal determines that 1slot (time offset) after receiving the calibration interval configuration information starts RRG calibration with 1s as a period, and calibrates 1 symbol in length.
Case 4, the network side calibration interval configuration information indicates that the calibration type of the terminal is an RRG (total gap) type, no cycle information, time offset 1slot, and calibration length 1 symbol, and the triggering event is that the output power reaches 23dBm; the terminal starts RRG power calibration based on a trigger event at 1slot (time offset) after receiving the calibration interval configuration information, and initiates calibration work in units of 1 symbol if the PA transmit power is equal to 23 dBm.
It should be understood that the foregoing is only an example, and other time offsets, calibration types, trigger events, and other settings may exist, which are not exhaustive in the embodiment.
Further, the terminal device can autonomously select a time resource for calibration according to the calibration interval configuration information, where the specific time resource includes at least one of the following: measurement gap (measurement gap), DRX, GP (guard period) within a special subframe, interrupt time resource, etc., but is not limited to the above time resource.
Wherein, the interruption time includes but is not limited to at least one of the following:
transition duration between DRX activation and deactivation;
the conversion duration between the addition and deletion of the Scell;
a transition duration between activation and deactivation of the Scell;
a length of time of measurement of the SCC;
the duration of RRC reconfiguration is controlled by uplink UL carrier wireless resources;
the transition duration of the active bandwidth part BWP.
The first processing unit 42 selects a time window before signal transmission based on the time resource; wherein the time window is all or part of the time length from power off to power on; and calibrating the target calibration type based on the selected time window.
Wherein, the first processing unit 42 performs power ramp-up within the time window; after the power ramp-up is completed, the calibration is performed in the target calibration type for the remainder of the time window.
Specifically, the foregoing calibration type may be TG or RRG calibration, and a specific processing flow may include:
for RRG calibration (but of course also for TG calibration), the terminal autonomously selects a time window before sending the signal for calibration; the selection of the time window may be determined according to the time resource, for example, if it is determined that the duration between the times 1-2 may be calibrated according to the measurement interval, the time window between the signals is selected between the times 1-2 to be calibrated; alternatively, the time window between the transmitted signals may be selected for calibration when the occurrence of a triggering event is detected.
Wherein the time window is all or part of the time length from power off to power on; specifically, all or a portion of the time in the transition time between power OFF to power ON. For example, the total time refers to the time when the terminal device uses the total transition time to perform PA calibration; the fractional time is the remaining time for power calibration if the UE completes the power ramp-up from OFF to ON before the specified time.
It should be noted that, the PA calibration is performed at all times of the time window, and may be performed after completing power ramp-up in the transition period, where the ramp-up time + the power calibration time and the total time less than or equal to the time window, that is, the power transition time, are performed.
For another example, the time other than the transition time from power OFF to power ON may be an ON procedure initiated in advance for the terminal, that is, the transition start time from OFF to ON is advanced, and after the power boost is completed, the UE performs power calibration in the remaining time.
The first processing unit 42, working in a training mode of DPD calibration during calibration, performs successive measurement and successive approximation on the chip related calibration circuit step by step, and finally obtains an inverse function close to the PA complex gain curve of the transmission path, that is, obtains compensation coefficients corresponding to different amplitudes and records them in a compensation coefficient table.
Specifically, for TG calibration, the first processing unit 42 works in a training working mode of calibration within a calibration time window, and the chip-related calibration circuit calibrates the DC Offset and the IQ impedance of the receive path first, and then calibrates the DC Offset and the IQ impedance of the transmit path; and step-by-step successive measurement and successive approximation are carried out to finally obtain an inverse function close to a complex gain curve of a transmitting path (mainly PA), and the inverse function is recorded in a compensation coefficient table.
Calibrating the RRG, wherein when the UE works in a calibrated training working mode in a calibration time window, a chip related calibration circuit firstly calibrates the transmitting power of a receiving access and then calibrates the transmitting power of a transmitting access; and step-by-step successive measurement and successive approximation are carried out, and finally an inverse function close to a complex gain curve of a transmitting path (mainly PA) can be obtained and recorded in a compensation coefficient table.
Wherein, the DPD is specifically described as follows:
calibrating DC Offset and IQ imbalance im balance of a receiving path by a chip related calibration circuit, calibrating DC Offset and IQ imbalance im balance of a transmitting path, generating a complex source waveform series by tracking _ gen, and acquiring initial complex gain to update to a DPD compensation Table (LUT, look Up Table); generating a first step signal (each step is a direct current or single-tone waveform) by Training _ gen to obtain a first complex response of the whole loop to the step signal, calculating a corresponding complex gain correction value through a difference value of the signal after the complex gain compensation and the response signal, and updating the complex gain correction value into a DPD LUT table; continuing to generate a second step signal from Training _ gen, similarly obtaining a second complex response and updating the LUT table; and step-by-step successive measurement and successive approximation are carried out, and finally an inverse function close to a complex gain curve of a transmitting path (mainly PA) can be obtained and recorded in a compensation coefficient table, namely an LUT table.
After calibration is completed, in a sending working mode, determining a transmission signal amplitude and a phase compensation coefficient through a compensation coefficient table obtained through calibration, carrying out complex multiplication to obtain a modulation waveform after DPD processing, and transmitting the modulation waveform through an antenna; the compensation coefficient table contains different signal amplitudes and different object relations between phase compensation coefficients.
That is to say, after the terminal device completes calibration in the selected time window, when the terminal device sends the working mode, the LUT table is used to find out the amplitude and phase compensation coefficient of the transmitted signal, and complex multiplication is performed to obtain a DPD processed modulation waveform, which is radiated through the antenna.
According to the standardized conclusion of the RAN4, the influence of the sending signal in the transition time from OFF to ON ON the system can be ignored, so that the influence of the sending interference in the PA calibration stage ON the system can be effectively reduced.
It can be seen that, by adopting the above scheme, the target calibration type can be calibrated based on the selected time resources, where the time resources may include a measurement interval (measurement gap), DRX, GP within a special subframe, an interruption time resource, and the like. In this way, an accurate calibration time pattern can be determined, and since the calibration can be performed in the interrupt time resource, interference of the calibration process with other terminal devices can be reduced.

Case 3, the network side calibration interval configuration information indicates that the calibration type of the terminal is an RRG (rank correct gap) type, the period calibration is performed with a calibration period of 1s, a time offset of 1slot, a calibration length of 1 symbol, and no trigger event information; the terminal determines that 1slot (time offset) after receiving the calibration interval configuration information starts to perform RRG calibration with 1s as a period, and the calibration length is 1 symbol.
