The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0110] In some embodiments, the core network device may be a device including one or more network elements, or may be multiple devices or a group of devices including one or more network elements, or may be physical. The core network may include, for example, at least one of an evolved packet core (EPC), a 5G core network (5GCN), and a next generation core (NGC).

Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0112] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1a, or a portion thereof, but are not limited thereto.

[0113] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0114] In some embodiments, the terminal can be enhanced to achieve higher transmit power under carrier aggregation (CA) / dual connectivity (DC). For terminals equipped with dual power amplifiers (PAs), CA / DC can be supported. For example, for a terminal with a power class (PC2) defined as PC2, the terminal's PA capabilities can vary across different frequency bands. For example, Table 1 shows the terminal power configuration.

[0115] Table 1

[0116] As shown in Table 1, carrier X and carrier Y are used to represent different bands. Table 1 shows that if the terminal's power level on one frequency band is limited to 23 decibel milliwatts (dBm), and the power level on another frequency band is also limited to 23dBm, the terminal's power level is limited to a maximum of 26dBm. For example, in combinations b and c, if the terminal's power level on one frequency band is limited to 23dBm and the power level on another frequency band is limited to 26dBm, the terminal's power level is limited to a maximum of 26dBm due to relevant protocol regulations. Combination d, similarly, is limited to a maximum of 26dBm due to relevant protocol regulations. In other words, the terminal's maximum transmit power is limited to the terminal power level specified in the protocol. In the Release 17 work item (WI) on increasing the terminal power cap for CA / DC, for a band combination where one band supports power levels up to PC3 (23dBm) and the other band supports power levels up to PC2 (26dBm), it can be assumed that the total power associated with the band combination is the sum of the power levels.

[0117] In some embodiments, the power level of the terminal is specified, so in some cases, a new capability signaling is introduced for each frequency band combination. That is, a new maximum output power (MOP) capability signaling is introduced to support this relaxed signaling, for example, the signaling can be HigherPowerLimitCADC. This signaling can be applicable to terminals in a CA scenario, where the power level sent in one frequency band supports PC3 and the power level sent in another frequency band supports PC2. The frequency band can, for example, be a frequency band using time division duplexing (TDD) or frequency division duplexing (FDD). The terminal can use the new MOP capability and use the full power from the two PAs corresponding to a maximum composite power of 27.8dBm. However, the terminal relative to R16 will be limited to PC2 in the CA / DC configuration.

[0118] In some embodiments, the key to enabling simultaneous transmission across multiple frequency bands is that terminals must comply with regulatory constraints when participating in uplink transmissions. Regulatory constraints on the total RF exposure experienced by users require terminals to determine a safe transmit power level for each frequency band, i.e., the RF exposure level. When a terminal approaches or exceeds the permitted RF exposure level, the terminal needs to recalculate the safe transmit power for each frequency band in use, and uplink transmissions will also result in a change in transmit power. Of course, in some cases, the terminal can set its transmit power to have a fixed limit so that the terminal never exceeds the RF exposure level limit.

[0119] However, because changes in terminal transmit power are transparent to network devices, meaning they are unaware of the reasons for these changes, these changes can affect their perception of link quality and link adaptation, which can subsequently lead to fluctuations in uplink throughput. Clearly, enabling network devices to better understand these constraints and their impact on terminal behavior can help them make more nuanced and accurate scheduling decisions.

[0120] In some embodiments, two types of RF exposure level limit indicators can be used, depending on the combination of frequency bands. For example, one type can use the specific absorption rate (SAR) as a metric, which is mainly applicable to frequency bands below 6 GHz, such as frequency range (FR)1. The other type can use the power density (PD) measurement and the calculation of the maximum permissible exposure (MPE) as a metric. This type of standard is mainly used in millimeter wave bands, such as FR2. Both of these indicators use a time-averaged method to limit RF exposure. That is, the average RF exposure measured using these indicators and within a specific event window must remain below a specific threshold. However, it is understandable that the protocol specifies average RF exposure, not instantaneous RF exposure. Of course, there may be some exceptions in specific areas. The time-averaged nature of the above constraints is particularly important when implementing high-power transmission at the terminal. This means that while the terminal cannot always transmit at full power on all frequency bands, it can transmit at a higher transmit power for a short period of time.

[0121] During uplink transmission, a terminal determines the maximum uplink duty cycle (UL duty cycle) it can support, also known as the maximum UL duty cycle, during the initial access phase based on SAR / MPE requirements within the uplink evaluation period. It then reports maxUplinkDutyCycle to the network device. After establishing a communication connection with the network device, the network device configures the terminal based on the reported maximum uplink duty cycle. This value, referred to as maxULdutycycle or maxUplinkDutyCycle, is used in subsequent transmissions. During the uplink evaluation period, the terminal controls actual uplink transmissions based on the symbol percentage corresponding to the maximum uplink duty cycle configured by the network device. However, these adjustments are transparent to the network device. Furthermore, because some countries / regions may specify mandatory SAR / MPE radiation exposure requirements for terminals in different frequency bands, terminals must meet the UL duty cycle requirements through actual transmission during the uplink evaluation period to comply with SAR / MPE requirements.

[0122] For example, Figure 1b shows a schematic diagram of terminal cumulative transmit power control. The gray area indicates that the terminal's total transmit power must meet the transmit power limit within a UL duty cycle. It can be understood that this transmit power limit is a power limit (e.g., 23dBm) determined on the carrier / cell to meet SAR / MPE requirements. It can be understood that this power limit can be either a SAR limit or an MPE limit. In Figure 1b, the terminal maintains an average transmit power within the UL duty cycle that meets the transmit power limit.

[0123] In practice, the terminal's transmit power can be below the transmit power limit in some transmit timeslots and above it in other transmit timeslots, as shown in Figure 1c. As Figure 1c shows, the terminal only needs to ensure that the average transmit power per uplink transmission symbol corresponding to the actual UL duty cycle percentage within the uplink evaluation period does not exceed the transmit power limit. Of course, while the instantaneous transmit power in a timeslot can exceed the transmit power limit, it must still meet the terminal's maximum transmit power requirement and cannot exceed the maximum transmit power.

[0124] In some cases, as shown in Figure 1d, the terminal may use the maximum transmit power to transmit uplink data in some time slots. To ensure that the average transmit power per uplink transmission symbol corresponding to the actual UL duty cycle ratio within the uplink evaluation period meets the transmit power limit, the terminal will be unable to transmit uplink data during the subsequent transmission time. That is, the terminal suspends transmission during this period. Even if the terminal may need to send data during this period, it cannot continue to send data.

[0125] In some embodiments, the terminal may use maxUplinkDutyCycle to avoid non-CA SAR / MPE issues for high power user equipment (HPUE). For CA scenarios, this issue can be avoided by the UE.

[0126] In some embodiments, due to high-order modulation and transmission bandwidth configuration, the terminal is allowed to reduce the maximum transmission power. For example, for terminal PC2, Table 2 defines the maximum power reduction (MPR) allowed for channel bandwidths that meet the following two criteria; for terminal PC3, Table 3 defines the maximum power reduction (MPR) allowed for channel bandwidths that meet the following two criteria.

[0127] Table 2

[0128] Table 3

[0129] Wherein, Pi in Table 2 and / or Table 3 may be π.

[0130] In some embodiments, the additional emission requirement may be notified to the terminal via network signaling. Each additional emission requirement is associated with a unique network signaling (NS) value, which is indicated by the NR band number of the applicable operating frequency band and the associated value in the field in the radio resource control (RRC) signaling. For example, the NR band number of the applicable operating frequency band and the associated value in the field may be additional spectrum emission.

[0131] For example, to meet additional requirements, additional maximum power reduction is allowed for the maximum output power specified in Table 2 and / or Table 3.

[0132] (Additional Maximum Power Reduction, A-MPR). Unless otherwise specified, the total reduction in maximum transmission power of a terminal is the maximum of MPR and A-MPR. MPR refers to the above description.

[0133] In some embodiments, the terminal is allowed to set the configured maximum output power for the carrier of the serving cell in each time slot. For example, the configured maximum output power P is set for the carrier f of the serving cell c. CMAX,f,c .

[0134] Optionally, P CMAX,f,c The value of P CMAX_L,f,c and P CMAX_H,f,c Between. That is Among them, P CMAX,f,c is the maximum transmit power, P CMAX_L,f,c is the lower value of the maximum transmit power, P CMAX_H,f,c The high value of the maximum transmit power.

[0135] Optionally, P CMAX_L,f,c Determined based on Formula 1: P CMAX_L,f,c =MIN{P EMAX,c -ΔT C,c (P PowerClass -ΔP PowerClass )-MAX(MAX(MPR c +ΔMPR c ,A-MPR c )+ΔT IB,c +ΔT C,c +ΔT RxSRS ,P-MPR c)} Formula 1

[0136] Where, f represents the carrier frequency, c represents the serving cell, and P EMAX,c Indicates the maximum allowable power of the network device configuration, P PowerClass Indicates the terminal defined power without considering other non-ideal factors (tolerance), ΔP PowerClass Indicates that the maximum power of the terminal is reduced or the power fallback value is configured based on the duty cycle to ensure RF radiation exposure, MPR c Indicates the maximum power reduction due to modulation mode and transmission bandwidth configuration factors, A-MPR c Indicates the additional power backoff required by network signaling to ensure the relevant radiation requirements of different operating frequency bands, ΔT IB,c Indicates the additional power back-off value under multi-carrier, ΔT C,c Indicates the additional power backoff value corresponding to the transmission of special edge configuration, ΔT RxSRS Indicates the terminal power adjustment value related to SRS antenna switching, P-MPR c Indicates the maximum power reduction of power management.

[0137] Optionally, P CMAX_H,f,c Determined based on Formula 2: P CMAX_H,f,c =MIN{P EMAX,c ,P PowerClass -ΔP PowerClass} Formula 2

[0138] In some embodiments, it is considered that the actual uplink transmission controlled by the terminal may change based on the terminal implementation, and these operations are transparent to the network device. Therefore, the terminal can report to the network device the instantaneous transmit power of the physical uplink shared channel (PUSCH) transmission. For example, the network device is reported by means of a power headroom report (PHR). The PHR may include power headroom (PH), maximum transmit power PCMAX,f,c and power-maximum power reduction (P-MPR). Among them, the power headroom reflects the amount of additional transmit power that the terminal can deliver with reference to the current PUSCH power level, and PCMAX,f,c reflects the maximum power that the terminal can deliver in this case, and the current protocol stipulates that P-MPR is only reported for the FR2 band. It can be understood that the PHR provides an instantaneous snapshot of a set of parameters for reporting specific PUSCH transmissions of the network device.

[0139] For example, Figure 1e shows the currently specified PHR configuration format for a single carrier. The P indication field is used to indicate whether there is MPE; the reserved bit can be denoted as R. It can be understood that the reserved bit does not usually contain any information and is mainly used to record the corresponding newly added data when necessary. The power margin is the above-mentioned PH, where in the case of a single carrier, the PH information corresponds to the PUSCH of the terminal, that is, type 1. At the same time, the PH is the PH corresponding to the primary cell (PCell). MPE or reserved bit indicates that this field can be MPE-related information or a reserved bit. Among them, the MPE-related information is used to record P-MPR in the case of FR2.

[0140] For another example, Figure 1f shows the PHR configuration format in a multi-carrier case. Among them, C1 to C7 can be used to indicate the PHR corresponding to different carriers respectively. It can be understood that the multi-carrier PHR can be regarded as a combination of multiple single-carrier PHRs. Type 2 can correspond to the physical uplink control channel (PUCCH), and the special cell (SpCell) can include a PCell and a primary secondary cell (PSCell). The serving cell can be a PCell, a secondary cell (SCell), a PSCell, or a SpCell, etc.

[0141] In some implementations, uplink coverage has long been a bottleneck for system performance, impacting signal quality and user experience. Operators, including operators, have a strong demand for enhanced uplink coverage. In the R18 coverage enhancement (CE) research, power domain enhancement is a worthy topic, as it has the most direct impact on improving both coverage and spectral efficiency (SE).

[0142] In NR uplink CA / DC, the maximum transmit power defined on a BC is limited by the UE transmit power class defined on that BC. However, the RAN4 enhancements in Release 17 support HPUEs to better utilize the UE's independent PA to achieve higher transmit power, primarily by enhancing the PC2+PC3 configuration.

[0143] During actual uplink transmission, terminals are limited by SAR requirements for FR1 and MPE requirements for FR2, limiting their actual transmit power. Transmit power adjustments based on SAR / MPE requirements may also cause significant fluctuations or interruptions in transmit power. Based on the RAN4 protocol, terminals define this type of implementation as transparent to network equipment. These power limits and adjustments, as well as the ability of HPUEs to achieve high-power transmission, significantly impact network equipment scheduling and directly influence the effectiveness of R17 enhancements deployed in network equipment. By enabling network equipment to understand terminal power information and its corresponding behavior, network equipment can make better scheduling decisions.

[0144] Obviously, how to enable network equipment to obtain power-related information of the terminal is a problem that needs to be solved.

[0145] Therefore, the present disclosure facilitates better network scheduling by transmitting the terminal's power level, which is more suitable for the scheduling of service transmission needs. This in turn improves system throughput and user coverage, helps improve system efficiency, reduces ineffective scheduling of network equipment, and saves unnecessary power consumption for terminals.

[0146] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:

[0147] Step S2101 , the terminal 101 sends second information to the network device 102 .

[0148] In some embodiments, the network device 102 receives the second information sent by the terminal 101 .

[0149] In some embodiments, terms such as "send", "transmit", "report", "download", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0150] In some embodiments, "obtain", "get", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining by self-processing, autonomous implementation, etc.

[0151] In some embodiments, the second information is used to indicate the amount of the second granularity.

[0152] In some embodiments, the second granularity amount is used to determine a second starting time of the first duration of the terminal.

[0153] For example, assuming that the number of second granularities is M, the third duration corresponding to the second granularity is K. The second starting time is the time corresponding to when the SFN is 0 and M*K has passed.

[0154] For example, when the third duration K corresponding to the second granularity is 100 ms and the number of second granularities M is 1, the second starting time is the moment 100 ms after SFN reaches 0. When the number of second granularities M is 2, the second starting time is the moment 200 ms after SFN reaches 0.

[0155] It can be understood that when the number of the second granularity can also be 0, the second starting time is the time corresponding to SFN 0.

[0156] In some embodiments, the second granularity may be equal to the third duration.The second starting time may be a time determined based on the number of reference points and the third duration.

[0157] For example, assuming that the number of the third durations is M, and the size of the third duration is K. The second starting time is the time corresponding to when the SFN is 0 and M*K has passed.

[0158] The first duration of the terminal is used to represent an estimated duration of at least one of the first power level and the third power level of the terminal.

[0159] The first power level is used to indicate the power level of the terminal after the power level falls back to a low level, and the third power level is used to indicate the power level of the terminal after the power level is restored.

[0160] For example, when the terminal experiences power level fallback, the first duration may be used to indicate an estimated duration of the first power level.

[0161] For another example, when the power level of the terminal is restored, the first duration may be used to indicate an estimated duration of the third power level.

[0162] In some embodiments, the terminal 101 sends second information to the network device, and the network device 102 can determine the number of second granularities based on the second information, and then determine the second starting time of the power level duration after the power level changes, so as to facilitate better scheduling of the network.

[0163] In some embodiments, the name of the second information is not limited, and it can be, for example, "granularity information", " ", etc.

[0164] In some embodiments, the names of information, etc. are not limited to the names described in the embodiments, and terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codeword", "codebook", "codeword", "codepoint", "bit", "data", "program", etc. can be used interchangeably.

[0165] In some embodiments, terms such as "certain", "preset", "preset", "setting", "indicated", "a certain", "any", and "first" can be interchangeable. "Specific A", "preset A", "preset A", "setting A", "indicated A", "a certain A", "any A", and "first A" can be interpreted as A pre-specified in a protocol, etc., or as A obtained through setting, configuration, or indication, etc., or as specific A, a certain A, any A, or first A, etc., but not limited to this.

[0166] In some embodiments, terms such as "moment", "time point", "time", and "time position" can be replaced with each other, and terms such as "duration", "period", "time window", "window", and "time" can be replaced with each other.

[0167] Step S2102 , the terminal 101 sends first information to the network device 102 .

[0168] In some embodiments, the network device 102 receives the first information sent by the terminal 101 .

[0169] In some embodiments, the terminal 101 sends the first information via the PHR.

[0170] For example, the PHR includes the first information.

[0171] Optionally, in response to a power level fallback, the terminal triggers a PHR report.

[0172] Optionally, in response to the transmit power level recovery, the terminal triggers PHR reporting.

[0173] For example, the PHR reporting is triggered when the terminal undergoes level fallback, which may be after the terminal undergoes level fallback.

[0174] For another example, the PHR report is triggered when the terminal undergoes level fallback. This may be when the terminal is about to undergo level fallback but has not yet undergone level fallback, thus triggering the PHR report.

[0175] For another example, the PHR reporting is triggered when the terminal recovers its level. This may be after the terminal recovers its level and then triggers the PHR reporting.

[0176] For another example, the PHR reporting is triggered when the terminal undergoes level recovery. This may be when the terminal is about to undergo level recovery but has not yet undergone level recovery, thus triggering the PHR reporting.

[0177] For example, the power level of the terminal may be PC1.5, PC2, PC3, etc. Among them, the maximum transmit power of the terminal of PC1.5 is 29dBm, the maximum transmit power of the terminal of PC2 is 26dBm, and the maximum transmit power of the terminal of PC3 is 23dBm.

[0178] Of course, the above-mentioned PC1.5, PC2, PC3, etc. are only illustrative examples, and the power levels are not limited thereto, and this disclosure does not give examples one by one.

[0179] Optionally, the power level fallback may be a fallback to a first power level, where the first power level is lower than a second power level, and the second power level is used to represent a power level defined and / or initially reported by the terminal.

[0180] The power level defined by the terminal and the power level initially reported by the terminal may be the same or different.

[0181] For example, if the terminal defines a power level of PC1.5, but the terminal falls back to PC2 after power level fallback, the power level initially reported by the terminal may be PC2. In this case, the power level defined by the terminal and the power level initially reported by the terminal are different.

[0182] For example, the power level fallback may be to fall back to any power level lower than the power level defined and / or initially reported by the terminal.

[0183] For example, the power level fallback may be from PC1.5 to PC2, or from PC1.5 to PC3.

[0184] Optionally, the power level fallback may be a step-by-step fallback or an alternate-level fallback.

[0185] For example, rolling back from PC1.5 to PC3 can be done from PC1.5 to PC2, and then from PC2 to PC3. This can be considered a step-by-step rollback.

[0186] For another example, rolling back from PC1.5 to PC3 can also be done directly from PC1.5 to PC3. In this case, it can be considered as a step-by-step rollback.

[0187] For another example, the power level recovery may be recovery from the current power level to a power level defined by the terminal, or recovery to a power level initially reported by the terminal.

[0188] Optionally, the power level recovery may be performed step by step or alternately.

[0189] For example, restoring from PC3 to PC1.5 can be done from PC3 to PC2, and then from PC2 to PC1.5. This can be considered a step-by-step recovery.

[0190] For another example, restoring from PC3 to PC1.5 can be done directly from PC3 to PC1.5, which can be considered as a step-by-step restoration.

[0191] It can be understood that the above-mentioned power level fallback and power level recovery are merely illustrative examples, and the present disclosure does not limit them.

[0192] Optionally, when an uplink transmission duty cycle corresponding to the PUSCH sent by the terminal is greater than a first threshold corresponding to the current power level, it is determined that a power level fallback occurs.

[0193] Optionally, when an uplink transmission duty cycle corresponding to the PUSCH sent by the terminal is greater than a first threshold corresponding to the current power level, it is determined that a power level fallback occurs.

[0194] For example, the first threshold may be the configured maxUplinkDutyCycle. That is, when the actual duty cycle exceeds the configured maxUplinkDutyCycle, power level fallback occurs.

[0195] Optionally, when an uplink transmission duty cycle corresponding to the PUSCH sent by the terminal is less than a first threshold corresponding to the current power level, it is determined that a power level fallback occurs.

[0196] Optionally, when an uplink transmission duty cycle corresponding to the PUSCH sent by the terminal is equal to a first threshold corresponding to the current power level, it is determined that power level fallback occurs.

[0197] For example, when the actual duty cycle does not exceed the configured maxUplinkDutyCycle, power level recovery occurs.

[0198] For example, the actual duty cycle is the duty cycle counted in real time during the current evaluation period.

[0199] Optionally, when the terminal enters a next evaluation period, the power level is restored.

[0200] It is understood that when the uplink transmission duty cycle corresponding to the PUSCH sent by the terminal is greater than the first threshold corresponding to the current power level, it can be determined that a power level fallback or a power level recovery has occurred. For example, the power level fallback or the power level recovery can be determined based on the terminal implementation. For another example, the power level fallback or the power level recovery can be determined based on a pre-determined rule.

[0201] For example, when the terminal enters the next evaluation period, it transmits according to the power level defined by the terminal, that is, the power level is restored to the power level defined by the terminal.

[0202] In some embodiments, terms such as "uplink", "uplink", "physical uplink" can be interchangeable with each other, and terms such as "downlink", "downlink", "physical downlink" can be interchangeable with each other, and terms such as "side", "sidelink", "side communication", "sidelink communication", "direct connection", "direct link", "direct communication", "direct link communication" can be interchangeable with each other.

[0203] In some embodiments, terms such as "physical downlink shared channel (PDSCH)" and "DL data" can be used interchangeably, and terms such as "physical uplink shared channel (PUSCH)" and "UL data" can be used interchangeably.

[0204] In some embodiments, the first information is used to indicate a power level of the terminal.

[0205] Optionally, the first information may include a first power level.

[0206] Optionally, the first information may include a third power level.

[0207] The first power level is used to indicate the power level of the terminal after the power level falls back to a low level, and the third power level is used to indicate the power level of the terminal after the power level is restored.

[0208] Optionally, the third power level after the power level is restored may be the second power level, that is, the third power level may be the same as the second power level.

[0209] Optionally, the power level after power level recovery may be a power level other than the second power level. That is, the third power level may be different from the second power level. For example, if the terminal defines a power level of PC1.5 and the terminal's current power level is PC3, the power level after power level recovery may be PC2, rather than the terminal's defined power level of PC1.5.

[0210] Optionally, the first information may include a power level change.

[0211] For example, the power level change amount may include a power change amount based on a maxUplinkDutyCycle requirement.

[0212] It is understood that the power level change can be used to represent the power level. For example, if the terminal last reported a power level of PC1.5 and the terminal reported a power level change of -3dB, the network can determine that the terminal's current power level is PC2 based on PC1.5 and -3dB. For another example, if the terminal last reported a power level of PC2 and the terminal reported a power level change of 3dB, the network can determine that the terminal's current power level is PC1.5 based on PC2 and 3dB.

[0213] Of course, the above example of determining the current power level of the terminal based on the power level change is only for the convenience of explanation, and the present disclosure does not limit this. Optionally, the first information may include an evaluation period of the terminal.

[0214] In some embodiments, the first information is used to indicate a change in the power level of the terminal.

[0215] For example, the terminal sends first information, where the first information is used to indicate a power level change of the terminal, so that the network device can determine the power level change of the terminal.

[0216] For another example, the terminal sends first information, where the first information is used to indicate a power level change of the terminal, so that the network can determine the current power level of the terminal according to the power level change of the terminal.

[0217] Optionally, the evaluation periods of the various carriers are consistent, and the evaluation period in the first information is applied to each carrier.

[0218] Optionally, each carrier evaluation period is different, and each carrier evaluation period in the first information is reported independently together with the PH.

[0219] Optionally, the first information may include a first duration of at least one of the first power level and the third power level.

[0220] In some embodiments, the first duration is used to represent an estimated duration of at least one of the first power level and the third power level.

[0221] For example, when the terminal experiences power level fallback, the first duration may be used to indicate an estimated duration of the first power level.

[0222] For another example, when the power level of the terminal is restored, the first duration may be used to indicate an estimated duration of the third power level.

[0223] In some embodiments, the first information of each carrier is reported together with the power headroom.

[0224] Optionally, the power level and power headroom of each carrier are reported together.

[0225] Optionally, the power level change and power headroom of each carrier are reported together.

[0226] Optionally, the power level, power level change, and power headroom of each carrier are reported together.

[0227] In some embodiments, the terminal triggers PHR reporting in response to power level fallback, and the code point corresponding to the power level change in the PHR only includes support for the power level fallback situation.

[0228] For example, when the terminal triggers PHR reporting in response to power level fallback, the terminal may refer to Table 4-1, Table 4-2, Table 4-3, and Table 5 to determine the code point indication corresponding to the power level change in the PHR.

[0229] Table 4-1

[0230] or

[0231] Table 4-2

[0232] or

[0233] Table 4-3

[0234] Table 5

[0235] Tables 4-1, 4-2, and 4-3 illustrate the correspondence between the power level change indication field information reported in the PHR and the power level change amount. Tables 4-1, 4-2, and 4-3 support terminal capability levels up to PC1.5. The maximum transmit power of a PC1.5 terminal is 29 dBm. Table 5 illustrates the correspondence between the power level change indication field information reported in the PHR and the power level change amount. Table 5 supports terminal capability levels up to PC1. The maximum transmit power of a PC1 terminal is 31 dBm.

[0236] For example, when a terminal falls back from PC2 to PC3, the maximum transmit power of the terminal on PC2 is 26dBm, and the maximum transmit power of the terminal on PC3 is 23dBm. The power level change can be considered to be 3dB. In this case, the PHR reports the power level change corresponding to code point 01.

[0237] For example, when a terminal falls back from PC1.5 to PC3, the maximum transmit power of the terminal at PC1.5 is 29dBm, and the maximum transmit power of the terminal at PC3 is 23dBm. The power level change can be considered to be 6dB. In this case, the PHR reports the power level change corresponding to code point 02.

[0238] It is understood that the power level change of the terminal may be 0dB, 1dB, 3dB, 6dB, or 8dB, and different power level changes are indicated by different indicator code points. The indicator code point corresponding to the power level change in the PHR can be determined by referring to any of the above tables. The above table is only exemplary and is not limited in this disclosure.

[0239] For example, code point 03 can be used as a reserved code point, as shown in Table 4-1 and Table 4-3. It can also be used to indicate a power change of 0 dB, as shown in Table 4-2. It can also be used to indicate 8 dB, as shown in Table 5.

[0240] Optionally, the code point corresponding to the power level change amount reported by the PHR may be a code point corresponding to the power level change amount carried in a medium access control element (MAC-CE) corresponding to the PHR report.

[0241] In some embodiments, the terminal triggers PHR reporting in response to transmission power level fallback and power level recovery, and the code point corresponding to the power level change in the PHR includes support for power level fallback and power level recovery.

[0242] Exemplarily, when the terminal triggers PHR reporting in response to power level fallback and power level recovery, the terminal may refer to Table 6 to determine the code point indication corresponding to the power level change in the PHR.

[0243] Table 6

[0244] Table 7-1

[0245] Table 7-2

[0246] Among them, Table 6, Table 7-1 and Table 7-2 are used to represent the correspondence between the power level change indication field information reported in the PHR and the power level change.

[0247] For example, when a terminal falls back from PC2 to PC3, the maximum transmit power of the terminal on PC2 is 26dBm, and the maximum transmit power of the terminal on PC3 is 23dBm. The power level change can be considered to be -3dB. In this case, the PHR reports the power level change corresponding to code point 03.

[0248] For example, when a terminal falls back from PC1.5 to PC3, the maximum transmit power of the terminal at PC1.5 is 29dBm, and the maximum transmit power of the terminal at PC3 is 23dBm. The power level change can be considered to be -6dB. In this case, the PHR reports the power level change corresponding to code point 04.

[0249] For another example, when the terminal recovers from PC3 to PC2, the power level change can be considered to be 3dB. In this case, the PHR reports the power level change corresponding to code point 01.

[0250] For another example, when the terminal recovers from PC3 to PC1.5, the power level change can be considered to be 6 dB. In this case, the PHR reports the power level change corresponding to code point 02.

[0251] For example, code points 05 and 06 can be used as reserved code points, as shown in Table 6. They can also be used to indicate power changes of 8 dB and -8 dB, as shown in Table 7-1 and Table 7-2.

[0252] In some embodiments, the terms "codebook," "codeword," and "precoding matrix" may be used interchangeably. For example, a codebook may be a collection of one or more codewords / precoding matrices.

[0253] In some embodiments, the first information includes a first starting time of an evaluation period of the terminal.

[0254] In some embodiments, the first starting time is used to indicate a starting time of an evaluation period of the terminal.

[0255] In some embodiments, the evaluation period mentioned in the above embodiments may be an evaluation period of a transmission duty cycle of the terminal. The transmission duty cycle evaluation period may also be referred to as a duty cycle evaluation period of the terminal.

[0256] Optionally, the first starting time includes a time corresponding to a system frame number SFN (SFN) of 0.

[0257] The system frame number can be understood as the number of the wireless frame.

[0258] Optionally, the first starting time includes the time corresponding to when the SFN is 0 and after an offset.

[0259] For example, the offset may be predefined by a protocol or configured by network signaling, and the unit may be a radio frame / subframe / time slot / ms / s, such as directly predefined as 100ms, 200ms, etc., which is not limited in this disclosure.

[0260] For another example, the offset can be determined based on the number of granularities. For example, the default starting time of SFN=0 is the preset reference point, and the duration corresponding to the granularity is 100ms. When the number of granularities is 1, the actual offset is 100ms relative to the preset reference point. That is, in this case, the starting time of the terminal's duty cycle evaluation period is the reference point position 100ms after the starting time of SFN=0.

[0261] Of course, the above examples of 100ms and 200ms are just illustrative examples, and the present disclosure does not limit them.

[0262] In some embodiments, the first information includes a first duration of an evaluation period of the terminal.

[0263] In some embodiments, the first duration is used to represent the duration of an evaluation period of the terminal.

[0264] Optionally, the first duration is based on a quantity representation of a first granularity.

[0265] The first granularity corresponds to the second duration.

[0266] In some embodiments, the first granularity may be equivalent to the second duration, ie, the first duration is expressed based on a quantity of the second duration.

[0267] In some embodiments, the first granularity may represent a unit duration, that is, the first duration is represented based on the number of unit durations.

[0268] For example, if the duration corresponding to one granularity is preset, when the number of granularities is 2, the first duration is twice the duration corresponding to one granularity; and when the number of granularities is 3, the first duration is three times the duration corresponding to one granularity.

[0269] For example, if the first duration corresponding to the preset granularity number of 1 is 100ms, then when the granularity number is 2, the first duration can be determined to be 200ms; when the granularity number is 3, the first duration can be determined to be 300ms.

[0270] For another example, if the second duration is preset and the number of the second durations is 2, then the first duration is twice the second duration. For example, if the second duration is preset to 100ms, then when the number of the second durations is 2, then the first duration is 200ms.

[0271] For another example, if the unit duration is preset and the number of unit durations is 2, the first duration is twice the unit duration. For example, if the unit duration is preset to 100ms, then when the number of unit durations is 2, the first duration is 200ms.

[0272] Of course, the above examples of 100ms, 200ms, and 300ms are only for the convenience of explanation, and the present disclosure does not limit them.

[0273] Optionally, the first duration is represented based on the first value, and different first values ​​correspond to different preset first duration intervals.

[0274] For example, different first duration intervals A, B, and C are pre-set. A first value X is associated with the first duration interval A; a first value Y is associated with the first duration interval B; and a first value Z is associated with the first duration interval C. Therefore, when the first information includes the first value X, it can indicate that the first duration is interval A.

[0275] For example, the preset interval (100-200ms) corresponds to the first value 1, the preset interval (200-300ms) corresponds to the first value 2, and the preset interval (300-400ms) corresponds to the first value 3. When the first information includes the first value 1, it can indicate that the duration of the evaluation period is the duration interval (100-200ms). That is, the duration of the evaluation period may be a value between 100-200ms. When the first information includes the first value 2, it can indicate that the duration of the evaluation period is the duration interval (200-300ms).

[0276] Of course, the intervals given in the above examples are only for the convenience of explanation, and the present disclosure does not limit the size of the duration interval.

[0277] Optionally, the first duration is represented based on the second value, and different second values ​​correspond to different preset second durations.

[0278] For example, different durations are preset and associated with the second value. When the first information includes the second value, it can be indicated that the first duration is the duration corresponding to the second value.

[0279] For example, a first duration of 100ms is preset to correspond to a second value A, a first duration of 200ms is preset to correspond to a second value B, and a first duration of 300ms is preset to correspond to a second value C. When the first information includes the second value A, it can indicate that the duration of the evaluation period is 100ms. When the first information includes the second value B, it can indicate that the duration of the evaluation period is 200ms. When the first information includes the second value C, it can indicate that the duration of the evaluation period is 300ms.

[0280] Of course, the above examples of 100ms, 200ms, and 300ms are only exemplary and are not limited in this disclosure.

[0281] It can be understood that the first value and the second value can be in any form, such as numbers, letters, symbols, etc., and this disclosure does not limit them.

[0282] In some embodiments, the first information includes a second starting time of the first duration of the terminal.

[0283] In some embodiments, the second starting time is used to indicate the starting time of the first duration.

[0284] Optionally, the second starting time may be the time at which the PHR is sent.

[0285] Optionally, the second starting time may be the first starting time corresponding to the evaluation period.

[0286] Optionally, the second starting time may be determined based on the time when the SFN is 0 and the number of second granularities, wherein the second granularity corresponds to the third duration.

[0287] For example, assuming that the number of second granularities is M, the third duration corresponding to the second granularity is K. The second starting time is the time corresponding to when the SFN is 0 and M*K has passed.

[0288] For example, when the third duration K corresponding to the second granularity is 100 ms and the number of second granularities M is 1, the second starting time is the moment 100 ms after SFN reaches 0. When the number of second granularities M is 2, the second starting time is the moment 200 ms after SFN reaches 0.

[0289] It can be understood that when the number of the second granularity can also be 0, the second starting time is the time corresponding to SFN 0.

[0290] In some embodiments, the second granularity may be equal to the third duration.The second starting time may be a time determined based on the number of reference points and the third duration.

[0291] For example, assuming that the number of the third durations is M, and the size of the third duration is K. The second starting time is the time corresponding to when the SFN is 0 and M*K has passed.

[0292] In some embodiments, the terminal may send second information to the network device, where the second information is used to indicate the amount of granularity.

[0293] Optionally, the terminal may send the second information first and then send the first information.

[0294] Optionally, the terminal may send the second information and the first information simultaneously.

[0295] Optionally, the terminal may send the second information first, and there is no need to send the second information again subsequently.

[0296] Optionally, the terminal may send the second information each time it sends the first information.

[0297] Optionally, the second starting time may be a time determined based on a second reference point. The second reference point is a reference point adjacent to the time of sending the PHR among reference points obtained by dividing the evaluation period based on a third granularity. The third granularity corresponds to the fourth duration.

[0298] For example, assuming that the evaluation period is divided into N reference points based on the third granularity, the third granularity corresponds to the fourth duration. The PHR is sent between the i-th reference point and the i+1-th reference point, then the second starting moment can be the moment corresponding to the i-th reference point or the moment corresponding to the i+1-th reference point. The moment corresponding to the i-th reference point is the moment after the start moment of the evaluation period passes through i third granularities. The moment corresponding to the i+1-th reference point is the moment after the start moment of the evaluation period passes through i+1 granularities.

[0299] For example, assuming N is 5, the evaluation period is divided into 5 reference points, and the fourth duration corresponding to the third granularity is 100 ms. In this case, if the PHR is sent between the second and third reference points, that is, i is 2, the second starting time of the power level change duration can be determined based on the second reference point and be 200 ms. Alternatively, it can be determined based on the third reference point and be 300 ms.

[0300] In some embodiments, the third granularity may be equal to the fourth duration.The second starting time may be a time determined based on the fourth duration.

[0301] For example, assuming that the evaluation period is divided into N fourth durations based on the size of the fourth duration, if the PHR is sent between the second and third fourth durations, that is, i is 2, then the second starting time of the power level change duration can be determined based on the second fourth duration, i.e., 200 ms. Alternatively, it can be determined based on the third fourth duration, i.e., 300 ms.

[0302] Optionally, the second starting time may be a PUSCH sending time.

[0303] It can be understood that the way of expressing the duration of the power level change is the same as the way of expressing the duration of the power level, and the present disclosure will not elaborate on them here.

[0304] In some embodiments, the first information includes a fifth duration of the first duration of the terminal.

[0305] In some embodiments, the fifth duration is used to indicate the duration of the first duration.

[0306] Optionally, the fifth duration is represented based on a number of third granularities, wherein each third granularity corresponds to the same sixth duration, and the sixth duration is less than or equal to the fifth duration.

[0307] Optionally, the fifth duration is represented by the third value, wherein different third values ​​correspond to different second duration intervals, and the second duration interval is an interval in which the power level corresponds to a preset duration.

[0308] Optionally, the fifth duration is represented by the fourth value based on the fifth duration, wherein different fourth values ​​correspond to different durations corresponding to preset power levels.

[0309] It can be understood that the specific representation of the fifth duration can refer to the specific representation of the first duration mentioned above, and the present disclosure will not elaborate on it here.

[0310] In some embodiments, the first information further includes a maximum output power configured for the terminal. The maximum output power is determined based on the first output power, the power variation, and the MPR. The first output power is determined based on the second power level, the power variation and the MPR are determined based on the second power level, or the power variation and the MPR are determined based on the third power level.

[0311] For example, the maximum output power is determined based on the above-mentioned Formula 1 and Formula 2.

[0312] In some embodiments, the first output power may be P in Formula 1 PowerClass , the power change can be ΔP in formula 1 PowerClass The first output power level is determined based on the second power level, where the second power level is used to represent a power level defined by the terminal and / or initially reported by the terminal.

[0313] The power level defined by the terminal and the power level initially reported by the terminal may be the same or different.

[0314] Optionally, when the UL duty cycle of the terminal exceeds the maximum UL duty cycle and power level fallback occurs, the terminal may determine the power variation and the MPR based on the power level defined by the terminal.

[0315] For example, when the power level falls back from PC2 to PC3, the power change is determined based on the second power level, that is, the power change at this time does not include the power change corresponding to the power level fallback. The terminal refers to Table 2 above and determines the MPR based on PC2.

[0316] Optionally, when the UL duty cycle of the terminal exceeds the maximum UL duty cycle and power level fallback occurs, the terminal may determine the maximum transmit power based on the power level after the power level change.

[0317] For example, when the power level falls back from PC2 to PC3, the power change is determined based on the second power level, that is, the power change at this time includes the power change corresponding to the power level fallback. The terminal refers to Table 3 above and determines the maximum transmit power based on PC3.

[0383] FIG5 is a flow chart of a communication method according to an embodiment of the present disclosure. As shown in FIG5 , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0384] In step S5101, the terminal 101 sends first information, where the first information is used to indicate a full power mode corresponding to different power levels of the terminal.

[0385] Optional implementations of step S5101 may refer to step S2102 in FIG. 2 , step S3102 in FIG. 3 , and other related parts in the embodiments involved in FIG. 2 and FIG. 3 a , which will not be described in detail here.

[0386] In some embodiments, the above method may include the method of the above embodiments related to the communication system 100, the terminal 101, the network device 102, etc., which will not be repeated here.

[0387] In some embodiments, the above method may include the method of the above embodiments related to the communication system 100, the terminal 101, the network device 102, etc., which will not be repeated here.

[0388] The present disclosure also provides a communication method as follows:

[0389] In some embodiments, based on the PHR measurement report, the terminal reports terminal power information related to the current power level or the power level change.

[0390] In some embodiments, reporting may also be sending.

[0391] In some embodiments, the triggering condition for PHR reporting is: a change in power level.

[0392] Optionally, PHR reporting is triggered only when power level fallback occurs (i.e., when the actual duty cycle value exceeds the configured maxUplinkdutycycle value);

[0393] Optionally, a PHR report is triggered when power level fallback or power level recovery occurs (i.e., when the actual duty cycle value exceeds the configured maxUplinkdutycycle value);

[0394] Optionally, the condition for restoring the power level may be that the terminal starts a new evaluation period and resumes sending according to the power level defined by the terminal.

[0395] Optionally, the condition for power level recovery may be when the actual duty cycle value counted does not exceed the configured maxUplinkdutycycle value.

[0396] In some embodiments, the specific instruction method for reporting information is:

[0397] Report content 1: Power class reporting. Each carrier reports power headroom (PH) together with the power class.

[0398] Report content 2: Power level change, only report the power level change (ΔP PowerClass ); also report for each carrier and PH together.

[0399] Optionally, based on triggering a PHR reporting indication only when a power level fallback occurs, the corresponding change amount for the corresponding code point only includes the situation corresponding to the power level fallback. Based on different situations and terminal implementation methods, the power level fallback can be a step-by-step fallback method, such as PC2 fallback to PC3, or a step-by-step fallback method, such as PC1.5 directly fallback to PC3.

[0400] For the case where the reported code point only includes the fallback power level change, the terminal capability level supported by Table 4-1, Table 4-2, and Table 4-3 is up to PC1.5 (29dBm), and the terminal capability level supported by Table 5 is up to PC1 (31dBm).

[0401] As shown in Tables 4-1, 4-2, 4-3, and 5, when the terminal at PC2 falls back to PC3, the MAC-CE corresponding to the PHR report carries the code point 01 corresponding to the power level change. The defined table can be used to look up the fallback power level and determine that the power level reported by the terminal has a 3dB change.

[0402] Optionally, based on the occurrence of power level fallback or power level recovery, a PHR reporting indication is triggered, and the corresponding code point corresponding to the corresponding change amount considers the support of both power level fallback and power level recovery. Based on different situations and terminal implementation methods, power level fallback can be a step-by-step fallback method, such as PC2 falls back to PC3, or a step-by-step fallback method. For example, PC1.5 falls back directly to PC3. Accordingly, power level recovery can be a step-by-step recovery method, such as PC3 recovers to PC2, or a step-by-step recovery method, such as PC3 recovers directly to PC1.5.

[0403] As shown in Table 6, Table 7-1, and Table 7-2, when a terminal on PC 2 falls back to PC 3, the MAC-CE corresponding to the PHR report carries the code point 03, corresponding to the power level change. The defined table shows that the fallback power level corresponds to a -3dB change in the power level reported by the terminal. When a terminal on PC 3 returns to PC 2, the MAC-CE corresponding to the PHR report carries the code point 01, corresponding to the power level change. The defined table shows that the fallback power level corresponds to a 3dB change in the power level reported by the terminal.

[0404] Reporting content three: optional reporting evaluation period starting point T and time length L.

[0405] In some embodiments, the evaluation period starting point T may be a first starting time.

[0406] In some embodiments, the time length L may be a first duration.

[0407] Reporting method:

[0408] Optionally, the evaluation period of each carrier is consistent, and the reported value is applied to each carrier.

[0409] Optionally, the evaluation period of each carrier is different, and each carrier is reported independently together with the PH corresponding to each carrier.

[0410] Start Time:

[0411] 1)SFN=0.

[0412] 2) Starting from SFN=0 and passing through the offset offset.

[0413] length:

[0414] 1) If the granularity X of the predefined / configured duration is X=100ms and the reported duration Y is Y=3, then the corresponding reported duration is 300ms.

[0415] 2) Report the absolute value / mapped value based on the reporting time. For example, if the reporting time is in the corresponding mapping interval, such as 300ms is in the predefined interval 3 (corresponding to 300-400ms), then the mapping value 3 corresponding to interval 3 is reported.

[0416] Optionally, it is defined as selecting to report from a set of optional values.

[0417] Report content 4: Simultaneously report the estimated duration of the power level or power level change, which may include:

[0418] Start time predefined or reported: unit is time slot / frame:

[0419] 1) PHR reporting time;

[0420] 2) The starting point of the evaluation cycle; (valid when reporting content 3 is defined)

[0421] 3) Starting from SFN=0, the predefined or configured granularity K is used as the reference point. The specific starting point can be configured by the network. For example, if it is M, it starts at M*K. It can also be determined by other methods. For example, the starting point is determined by the PHR reporting time. If the PHR reporting time is between reference points i and i+1, it can start at i*K or (i+1)*K. It is similarly determined by the PUSCH transmission time.

[0422] 4) PUSCH transmission time.

[0423] Duration length reporting:

[0424] 1) If the granularity X of the predefined / configured duration is X=100ms and the reported duration Y is Y=3, then the corresponding reported duration is 300ms;

[0425] 2) Report the absolute value / mapped value based on the reporting time. For example, if the reporting time is in the corresponding mapping interval, such as 300ms is in the predefined interval 3 (corresponding to 300-400ms), then the mapping value 3 corresponding to interval 3 is reported;

[0426] 3) Defined as a set of optional values ​​to be reported;

[0427] In some embodiments, the duration estimate may be a first duration.

[0428] In some embodiments, the duration length may be the duration of the first duration.

[0429] It can be understood that the above examples of 100ms, 200ms, and 300ms are all illustrative examples, and the present disclosure does not limit them.

[0430] In some embodiments, when the terminal's transmission duty cycle exceeds the maximum transmission duty cycle (maxDutyCycle) capability and the PC changes, the network cannot determine the maximum transmit power (P) actually used by the terminal to report the corresponding carrier. CMAX,f, ) corresponds to the actual terminal power level, so it is necessary to determine the reported P CMAX,f, Rules that apply:

[0431] Optionally, the terminal power level remains unchanged and reports ΔP PowerClass Therefore, the MPR table corresponding to the MPR still corresponds to the power class configured by the terminal.

[0432] Optionally, the terminal power level remains unchanged and reports ΔP PowerClass , use the MPR table corresponding to the changed power level to calculate the configured transmission power.

[0433] In some embodiments, the MPR tables may be, for example, Table 2 and Table 3. Table 2 is the MPR table corresponding to PC2, and Table 3 is the MPR table corresponding to PC3.
