Related technology is known from 3GPP documents R4-<NUM>, R4-<NUM> and R4-<NUM>, and Chinese patent publication<CIT>.

Embodiments of the present disclosure provide a method for limiting uplink transmit power radiation and a related product in order to, for different frequency band combinations that a high power user equipment may support, formulate corresponding different transmission limitation rules by considering different duplex mode combinations, different maximum transmit power combinations, and whether the frequency band combinations support a single transmission or a dual transmission mode, and accordingly ensure the electromagnetic radiation requirements of the high power terminal (user equipment).

According to a first aspect, an embodiment of the present disclosure provides a method for limiting uplink transmit power radiation. The method is applied to a High Power User Equipment (HPUE) supporting a Dual Connectivity (DC) mode. The DC mode refers to dual connectivity based on a DC frequency band combination, and the DC frequency band combination comprises a Long Term Evolution (LTE) frequency band and a New Radio (NR) frequency band. The method includes:.

According to a third aspect, an embodiment of the present disclosure provides a device for limiting uplink transmit power radiation. The device is applied to a High Power User Equipment (HPUE) supporting a Dual Connectivity (DC) mode. The DC mode refers to dual connectivity based on a DC frequency band combination, and the DC frequency band combination comprises a Long Term Evolution (LTE) frequency band and a New Radio (NR) frequency band. The device includes a processing unit and a communication unit:
wherein the processing unit is configured to:.

As can be seen from above, in embodiments of the present disclosure, the high power terminal first determines the transmission power radiation limitation policy of the high power terminal in the DC mode, and then adjusts the uplink transmission configuration of the high power terminal according to the transmission power radiation limitation policy. The uplink transmission configuration comprises a Time Division Multiplexing (TDM) pattern for the DC frequency band combination or a maximum uplink duty cycle of the LTE frequency band and/or the NR frequency band in the DC frequency band combination. The high power terminal supports a Dual Connectivity (DC) mode, and the DC mode refers to dual connectivity based on the DC frequency band combination, and the DC frequency band combination comprises a Long Term Evolution (LTE) frequency band and a New Radio (NR) frequency band. It can be seen that the high power terminal in embodiments of the present disclosure can dynamically determine the transmission power radiation limitation policy in the DC mode, and adjust the local uplink transmission configuration according to the transmission power radiation limitation policy, that is, flexibly set the transmission restriction rules, so that the electromagnetic radiation requirements of the high power terminal in the uplink transmission procedure can be guaranteed.

The following will briefly introduce the drawings that need to be used in the description of embodiments or related arts.

The technical solutions in embodiments of the present disclosure will be described below with reference to the accompanying drawings.

As shown in <FIG> and <FIG>, the existing LTE Time Division Duplexing (TDD) configurations include seven configurations as shown in the figures (corresponding to <NUM>/<NUM>/<NUM>/<NUM>/<NUM>/<NUM>/<NUM> in <FIG>). For the LTE TDD frequency band, such as B41, the existing SAR solution is defined as follows in the standard: the TDD configurations of LTE are limited, and the basic principle is that a configuration of uplink (UL) duty cycle not exceeding <NUM>% is allowed; otherwise, the configuration is not allowed.

If UE supports a different power class than the default UE power class (generally, Power Class <NUM>, 23dBm) for EN-DC band combination, and the supported power class enables higher maximum output power than that of the default power class:.

The above-mentioned mechanism that satisfies SAR is also applicable to in-band continuous EN-DC combination (E-UTRA and NR dual connectivity), such as LTE B41+NR n41.

NR UL/DL configuration for EN-DC HPUE will follow LTE's TDD HPUE configuration, i.e., the max UL duty cycle is <NUM>%.

The NR TDD configurations are very flexible, and there are dozens of configurations, as shown in <FIG>.

SAR is the electromagnetic wave energy (dW) (<NUM>-<NUM>) absorbed by biological tissue per unit time (dt) or unit mass (dm or pdV). Limit: the average specific absorption rate SAR of any <NUM> biological tissue for any continuous <NUM> minutes shall not exceed <NUM>.

Note: SAR may be calculated according to the following formulas: <MAT> <MAT> where:.

For devices in frequency bands such as millimeter waves, another measurement index (power density) is used, which is generally applicable to frequency bands above <NUM>.

The folowing equation shows the relationship between the power per unit area perpendicular to the direction of propagation and electric and magnetic fields: <MAT> where:.

The distance below is a distance at which the field strength of electric field of the incident plane wave (of a given frequency) from the boundary of the lossy medium to the inside of the medium is attenuated to <NUM>/e of its original value. Plane waves are often generated in the half-space of the plane, and their penetration depth δ is determined by the following formula <NUM>. <MAT> where:.

At present, for the frequency band combination of LTE TDD + NR TDD (duplex mode), the following mechanism for LTE TDD PC3 + NR TDD PC3 is established to limit and report the uplink duty cycle.

UE based solution is FFS (for further study). Also solution to combine network and UE based solution will be FFS.

Based on the above existing progresses and conclusions, according to the countable UL/DL configurations for LTE TDD, only the maximum uplink duty cycle (maxUplinkDutyCycle) of the corresponding NR TDD needs to be reported, if the terminal behavior which the signaling does not report is still undefined. In addition to this method which relies on network-side scheduled restrictions, solutions that the terminal can autonomously implement, such as using a sensor to determine the power reduction or fallback of power class, are not ruled out.

In addition, for LTE TDD PC2+NR TDD PC3 and LTE TDD PC2+NR TDD PC2, the situations of HPUE may be different, and the working mechanism needs to be discussed.

For LTE FDD+NR TDD, taking LTE B3+NR n78 as an example, there is currently an approach in which LTE FDD will continue to use the UL/DL configurations for LTE TDD, as shown in <FIG>, <FIG>, and <FIG>. Based on this, whether the TDM pattern meets the requirements of the uplink duty cycle is further discussed. <FIG> shows the case of a feasible TDM pattern, and <FIG> and <FIG> show the case of a single transmission working state.

For some areas, the NR TDD configuration is clear, and the LTE FDD configuration may be specified. But in fact, NR is very flexible, and there are dozens of configurations, which will limit the flexibility of base station scheduling, and more than just these configurations can be supported.

Based on the above, the present disclosure formulates a complete and feasible uplink transmit power radiation limitation mechanism for all possible LTE+NR DC frequency band combinations and maximum transmit power combinations that may occur for HPUE, so as to flexibly and reliably guarantee the SAR requirements of the terminal.

The technical solutions will be described below in detail.

The present disclosure provides a method for limiting the uplink transmit power radiation. In addition to the autonomous power back-off of the terminal and the power adjustment triggered by a sensor, the present disclosure also mainly provides a method in which the terminal can report its capability indication based on different application scenarios and frequency band combinations, combined with base station scheduling, to ensure that the uplink transmit power statistics of the terminal do not go beyond the requirement, achieving the purpose of safety management of electromagnetic radiation.

According to duplex mode combinations for frequency band combinations, there are four combinations. For different maximum transmit power combinations and whether the frequency band combinations support a single transmission mode or a dual transmission mode, different transmission limitation rules may be formulated to ensure the electromagnetic radiation requirements of the terminal.

Table <NUM>, Table <NUM> and the program example <NUM> show all the situations of duplex modes, maximum transmit power, and the terminal capability of whether SUO is supported.

<FIG> is a method for limiting uplink transmit power radiation according to an embodiment of the present disclosure. The method is applied to a High Power User Equipment (HPUE) supporting a Dual Connectivity (DC) mode. The DC mode refers to dual connectivity based on a DC frequency band combination, and the DC frequency band combination comprises a Long Term Evolution (LTE) frequency band and a New Radio (NR) frequency band.

In step <NUM>, the HPUE determines a transmit power radiation limitation policy of the HPUE in the DC mode.

The transmit power radiation limitation policy includes any one of the following: (<NUM>) reporting capability indication combined with base station scheduling based on different application scenarios and frequency band combinations to ensure that the uplink power statistics transmitted by the terminal does not go beyond the requirement; (<NUM>) autonomous power back-off; (<NUM>) power adjustment triggered by a sensor.

In step <NUM>, the HPUE adjusts an uplink transmission configuration of the HPUE according to the transmit power radiation limitation policy. The uplink transmission configuration comprises a Time Division Multiplexing (TDM) pattern for the DC frequency band combination or a maximum uplink duty cycle of the LTE frequency band and/or the NR frequency band in the DC frequency band combination.

In a possible example, determining the transmit power radiation limitation policy of the HPUE in the DC mode comprises:.

The transmission mode includes a single transmission mode and a dual transmission mode, the duplex mode combination includes the combinations described in Table <NUM> above, and the maximum transmit power combination includes the combinations shown in Table <NUM> above.

It can be seen that in this example, for the frequency band combinations that HPUE may support, different duplex mode combinations, different maximum transmit power combinations and whether the frequency band combinations support the single transmission mode or the dual transmission mode are considered to formulate correspondingly different transmission restriction rules, to ensure the electromagnetic radiation requirements of the HPUE.

In a possible example, the at least one DC frequency band combination is a frequency band combination that supports the dual transmission mode, and the duplex mode combination is LTE Time Division Duplex (TDD)+NR TDD.

Adjusting, by the HPUE, the uplink transmission configuration of the HPUE according to the transmit power radiation limitation policy comprises:.

For the maximum transmit power combinations 23dBm+23dBm and 23dBm+26dBm, the LTE TDD configurations are countable and known, and the HPUE does not need to report its capabilities, and the HPUE only needs to limit the maximum uplink duty cycle of the corresponding NR TDD frequency band, and reports the capability information. The HPUE may report two sets of values (the maximum uplink duty cycle of the NR TDD frequency band as shown in Table <NUM>).

For the maximum transmit power combination 26dBm+26dBm, its LTE TDD configurations <NUM> and <NUM> are not applicable, and the maximum uplink duty cycle of the corresponding NR TDD frequency band is shown in Table <NUM>.

In a possible example, wherein the at least one DC frequency band combination is a frequency band combination that supports the dual transmission mode, and the duplex mode combination is LTE Frequency Division Duplex (FDD)+NR TDD;
adjusting, by the HPUE, the uplink transmission configuration of the HPUE according to the transmit power radiation limitation policy comprises:.

If the LTE FDD also supports TDD configurations (scheduled by the base station), the HPUE also needs to limit the maximum uplink duty cycle and report the capability like the NR TDD frequency band.

For the situation in which the LTE FDD frequency band supports the uplink and downlink configurations of the LTE TDD frequency band, HPUE needs to simultaneously limit the maximum uplink duty cycles of the LTE frequency band and the NR frequency band (combination of two duty cycles); for the three situations: 23dBm+23dBm, 23dBm+26dBm or 26dBm+ 26dBm, the HPUE reports three sets of values, as shown in Table <NUM>.

For the situation in which the LTE FDD frequency band does not support the uplink and downlink configurations of the LTE TDD frequency band, the worst case is that the HPUE needs to support continuous transmission (<NUM>% duty cycle, no additional reporting is required), and the HPUE only needs to report the maximum uplink duty cycle of the NR TDD frequency band. For the two situations: 23dBm+23dBm or 23dBm+26dBm, the HPUE reports two sets of values, as shown in Table <NUM>.

In the present invention, the at least one DC frequency band combination is a frequency band combination that supports a single transmission mode, and the duplex mode combination is LTE FDD+NR TDD;
adjusting, by the HPUE, the uplink transmission configuration of the HPUE according to the transmit power radiation limitation policy comprises:.

For the frequency band combination that supports that the single transmission mode:.

For 23dBm+23dBm, one value is reported, which can be <NUM>%; if the terminal is in the SUO state when it is connected to the network, the value may not be reported by default, and the network considers by default that there is no restriction for normal UE. For 23dBm+26dBm (currently, FDD 26dBm+TDD 26dBm is not considered):.

(<NUM>) If the base station configures a TDD pattern but the terminal is working in the dual Tx state, the UE needs to report the capability by default, that is, the UE needs to report the capability about the maximum uplink duty cycles that are supportable by LTE and NR, respectively, in the frequency band combination, as shown in Table <NUM>.

(<NUM>) If the base station configures a TDD pattern and the terminal is working in the SUO state, the UE needs to update or report the capability of this frequency band combination, i.e., the maximum uplink duty cycle (such as <NUM>%) of the NR TDD frequency band in the frequency band combination, and this value only needs to follow NR TDD. When the HPUE switches from Dual Tx to SUO or switches from SUO to Dual TX, the terminal needs to update this capability, as shown in Table <NUM>.

(<NUM>) If the base station does not configure a TDD pattern, the UE needs to report the capability of the maximum uplink duty cycles that can be supported by LTE and NR, respectively, in the frequency band combination, as shown in Table <NUM>.

For 23dBm+23dBm, no reporting is required by default.

For 23dBm+26dBm, it is needed to report the corresponding maximum uplink duty cycle (such as <NUM>%, generally less than or equal to <NUM>%) of the combination according to different LTE TDD configurations. But the values in the two cases are different.

For 26dBm+26dBm, LTE TDD configurations <NUM> and <NUM> are not applicable, and the corresponding maximum uplink duty cycle of the combination is reported, as shown in Table <NUM>.

In a possible example, the at least one DC frequency band combination is a frequency band combination that supports a single transmission mode, and the duplex mode combination is LTE TDD+NR TDD;
adjusting, by the HPUE, the uplink transmission configuration of the HPUE according to the transmit power radiation limitation policy comprises:.

In a possible example, determining, by the HPUE, the transmit power radiation limitation policy of the HPUE in the DC mode comprises:.

The regional feature can be, for example, "network signaling"-NS <NUM>, indicating China Regional <NUM>, US regional1, and there may be different corresponding SAR index requirements and terminal power fallback MPR (Maximum Power Reduction), and different restriction policies may be formulated.

In a possible example, adjusting, by the HPUE, the uplink transmission configuration of the HPUE according to the transmit power radiation limitation policy comprises:.

In a possible example, determining, by the HPUE, the transmit power radiation limitation policy of the HPUE in the DC mode comprises:
determining, by the HPUE, an autonomous power fallback policy of the HPUE as the transmit power radiation limitation policy in the DC mode.

In a possible example, determining, by the HPUE, the transmit power radiation limitation policy of the HPUE in the DC mode comprises:
determining, by the HPUE, a power adjustment policy of the HPUE which is based on sensor triggering as the transmit power radiation limitation policy in the DC mode.

As can be seen from above, the present disclosure provides a method for limiting the uplink transmission of a HPUE that supports a LTE + NR DC frequency band combination in a single transmission mode. Regarding the frequency band combinations that the HPUE may support, different duplex working modes, different maximum transmit power combinations, and whether the DC frequency band combinations support the single transmission mode or the dual transmission mode are considered, to formulate corresponding different transmission restriction rules to ensure the electromagnetic radiation requirements of the HPUE.

In addition, HPUE generally has a self-implemented sensor-based power back-off mechanism to meet the electromagnetic radiation requirements, and the present disclosure mainly assists in meeting the requirements from the perspective of network-side scheduling to limit the uplink transmission, which improves the reliability of the HPUE, and simplifies the design of the HPUE to some extent, and can even reduce the costs associated with sensors.
