AI Technical Summary
During P-MPR calibration, existing technologies suffer from excessively high P-MPR values and require waiting for a timer to expire before reporting a new P-MPR, resulting in low uplink transmit power and potentially causing uplink beam or link failure.
The terminal performs power or coverage enhancement or transceiver calibration autonomously or under the instruction of the base station, updates the P-MPR value, and controls the reporting of PHR by setting various thresholds and timer conditions, including periodic calibration by autonomous or network configuration and event-triggered calibration.
It effectively reduces the probability of uplink beam or link failure, and ensures the stability of uplink transmit power through reasonable calibration and PHR reporting mechanism.

Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the field of mobile communication technology, in particular to a P-MPR-based calibration method, device and computer readable storage medium. BACKGROUND
[0002] Currently, when the value of power management corresponding maximum power reduction (P-MPR) is greater than the maximum permissible exposure threshold (mpe-Threshold), a power headroom report (PHR) is reported, or after the last PHR is reported due to the value of P-MPR being greater than mpe-Threshold, the change value of P-MPR is greater than the threshold (phr-Tx-PowerFactorChange), the PHR is reported. The prerequisite for the above-mentioned PHR reporting is that the current timer (mpe-ProhibitTimer) has expired. The main function of the timer (mpe-ProhibitTimer) is to avoid frequent reporting of PHR caused by temporary changes in P-MPR in a short period of time.
[0003] For P-MPR calibration, if the existing calibration scheme is still followed, the terminal needs to wait for the timer mpe-ProhibitTimer to expire before it can report the PHR change value even after the calibration is completed. However, since P-MPR is already very large during P-MPR calibration, the uplink transmit power is too small, and if the terminal still waits for the timer mpe-ProhibitTimer to expire before reporting the new P-MPR, it may cause the uplink transmit power to be too low, resulting in uplink beam or link failure.

[0687] Wherein, the event-triggered calibration confidence factor is an event-triggered calibration confidence factor included in the calibration configuration information sent by the base station.
[0688] The application will be described below in conjunction with the scene embodiments.
[0689] For the P-MPR calibration scheme, if the existing related scheme is still followed, the terminal needs to wait for the timer mpe-ProhibitTimer to expire before reporting the PHR change value even after the calibration is completed, but the P-MPR is already large during the P-MPR calibration, resulting in too small uplink transmit power, and if the terminal still waits for the timer mpe-ProhibitTimer to expire before reporting the new P-MPR, it is possible to cause the uplink transmit power to be too low, resulting in uplink beam / link failure. At this time, the P-MPR is the calibrated P-MPR and is not a short-term temporary P-MPR value, and there is no need to wait for the timer mpe-ProhibitTimer to expire before reporting. Taking the P-MPR minimum calibration period of 5 ms as an example, for the millimeter wave prohibitTimer with a value of 25 ms (120 kHz), the calibration results of multiple calibration periods will not be reported, the base station does not know the actual P-MPR of the terminal, and the terminal is scheduled and power controlled based on the P-MPR before calibration, resulting in too small uplink transmit power or even uplink link failure.
[0690] The present embodiment is described from two parts of calibration trigger conditions of terminal power or coverage enhancement or transceiver calibration and P-MPR power headroom report (PHR) reporting conditions.
[0691] The calibration trigger conditions of the terminal power or coverage enhancement or transceiver calibration include periodic calibration and event-triggered calibration.
[0692] Here, the corresponding power or coverage enhancement or transceiver calibration process includes the following steps:
[0693] Step 1: The terminal reports one or more of the calibration candidate period, calibration duration, and calibration confidence factor (periodic calibration confidence factor, event-triggered calibration confidence factor) supported by the terminal;
[0694] The calibration candidate period and the calibration duration can be grouped according to the calibration confidence factor, that is, each calibration confidence factor corresponds to a calibration candidate period and a calibration duration.
[0695] For example, when the calibration confidence factor is 100%, the corresponding calibration period is 5 ms and the calibration duration is 62.5 us; when the calibration confidence factor is 50%, the corresponding calibration period is 20 ms and the calibration duration is 2 ms.
[0696] If multiple calibration candidate periods and calibration durations are reported, and no calibration confidence factor is reported, different calibration periods can correspond to certain default calibration confidence factors, for example, if 5 calibration candidate periods are reported, the 5 calibration periods correspond to 10%, 20%, 40%, 80%, and 90% calibration confidence factors by default; if only one calibration period is reported, a default calibration confidence factor is indicated, and the default calibration confidence factor can be 1.
[0697] The calibration confidence factor indicates the confidence of the P-MPR obtained after calibration according to the corresponding calibration period.
[0698] Step two: the base station configures the configuration parameters required for terminal power or coverage enhancement or transceiver (UE power / coverage enhancement) calibration for the terminal, including: calibration configuration period corresponding to periodic calibration, offset, duration, calibration confidence factor, calibration trigger event of event-triggered calibration, and event-triggered calibration confidence factor, etc., and instructs the terminal to start terminal power / coverage enhancement calibration;
[0699] The configuration parameters can be RRC, MAC CE activation, or DCI indication.
[0700] The trigger event for the base station to instruct the terminal to start calibration can be:
[0701] The value of the terminal P-MPR is greater than threshold A;
[0702] The change value of the terminal P-MPR within a certain time is greater than B.
[0703] Step three: the terminal starts power / coverage enhancement (UE power / coverage enhancement) calibration according to the current P-MPR, and the calibration trigger condition is:
[0704] If the P-MPR value is greater than threshold C (which can be the same as A), the terminal autonomously selects a moment when there is no uplink transmission information and no indication to receive downlink to start calibration work;
[0705] If the change value of the terminal P-MPR within a certain time is greater than D (which can be the same as B), the terminal autonomously selects a moment when there is no uplink transmission information and no indication to receive downlink to start calibration work.
[0706] For reporting of PHR trigger conditions containing P-MPR, the following steps are included:
[0707] Step one: the base station determines the PHR reporting parameter configuration according to the calibration candidate period reported by the terminal;
[0708] For example, the prohibitTimer parameter is set to be less than the calibration period, so that the calibration parameter in each period can be reported to the base station.
[0709] Step two: the terminal evaluates the P-MPR value after calibration, and starts PHR reporting.
[0710] Here, if the P-MPR calibration is periodic calibration configured by the network, and the network configures a periodic calibration credibility factor for the terminal or the periodic calibration credibility factor takes a default value, the PHR reporting trigger condition is that if the P-MPR is greater than a threshold X or the change value is greater than a threshold Y, and at this time the change of P-MPR is caused by power or coverage enhancement or transceiver calibration, then wait for
[0711] (1-periodic calibration credibility factor) * prohibitTimer,
[0712] or periodic calibration credibility factor * prohibitTimer;
[0713] After the timeout, stop the timer immediately and report PHR directly, at this time the PHR contains the P-MPR value, and start a new round of timer timing. If the above formula is not an integer multiple of subframes, rounding up, rounding down or rounding operation is needed to ensure that the value of the integer multiple of subframes is obtained.
[0714] If the P-MPR calibration is periodic calibration configured by the network, but the network does not assign a periodic calibration credibility factor, the default calibration credibility factor is used for calculation, and the default calibration credibility factor is 1, then the PHR reporting trigger condition is that if the P-MPR is greater than a threshold X or the change value is greater than a threshold Y, and at this time the change of P-MPR is caused by power or coverage enhancement or transceiver calibration, then wait for
[0715] (1-periodic calibration credibility factor) * prohibitTimer,
[0716] or periodic calibration credibility factor * prohibitTimer;
[0717] After the timeout, stop the timer immediately and report PHR directly, at this time the PHR contains the P-MPR value, and start a new round of timer timing. If the above formula is not an integer multiple of subframes, rounding up, rounding down or rounding operation is needed to ensure that the value of the integer multiple of subframes is obtained.
[0718] If the P-MPR calibration is event triggered, the PHR reporting trigger condition is that if the P-MPR is greater than a threshold X or the change value is greater than a threshold Y, and the change of P-MPR is caused by power / coverage enhancement calibration, then regardless of whether the timer is expired, the timer is stopped immediately and the PHR is reported directly, the PHR at this time contains the P-MPR value, and a new round of timer timing is started.
[0719] If the base station configures the event triggered calibration confidence factor or the event triggered calibration confidence factor is the default value, and the change of P-MPR is caused by power or coverage enhancement or transceiver calibration, then the PHR is reported after waiting for
[0720] (1-event triggered calibration confidence factor)*prohibit timer,
[0721] or event triggered calibration confidence factor*prohibit timer.
[0722] The timer is stopped when it is expired, the PHR is reported, and a new round of timer timing is started; wherein the PHR contains the P-MPR value.
[0723] In an embodiment of the present application, the PHR reporting trigger condition can include any of the following:
[0724] If the mpe-Reporting-FR2 parameter (which is used to indicate that the report is for FR2 scene to meet the electromagnetic radiation requirement) is configured, and since the last P-MPR report, the terminal has completed calibration, including but not limited to power and coverage enhancement calibration, then the PHR is reported if any of the following conditions is met:
[0725] If since the last PHR report, for at least one activated FR2 serving cell, the P-MPR is equal to or greater than the threshold (MPR-threshold), or
[0726] If since the last PHR report caused by P-MPR greater than the threshold (MPR-threshold), for at least one activated FR2 serving cell, the P-MPR change value is equal to or greater than the threshold (phr-Tx-PowerFactorChange), or
[0727] If since the last PHR report caused by P-MPR change value greater than the threshold (phr-Tx-PowerFactorChange), for at least one activated FR2 serving cell, the P-MPR change value is equal to or greater than the threshold (phr-Tx-PowerFactorChange).
[0728] The embodiment of the present application solves the technical problem of too low uplink transmission power caused by too large P-MPR and reporting new P-MPR after waiting for prohibitTimer to expire during P-MPR calibration, and can effectively reduce the probability of uplink beam or link failure.
[0729] The above merely describes the preferred embodiment of the present application, but should not be used to limit the protection scope of the present application.
