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.

[0175] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 .

[0176] 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).

[0177] For example, in one embodiment of the present disclosure, a terminal can be enhanced to achieve higher transmit power under CA / DC. For terminals equipped with dual power amplifiers (PAs), CA / DC is supported. Table 1 below shows the PA capabilities for different bandwidths, taking PC2 as an example. Table 1 illustrates the terminal power configuration. For cases c and d, the maximum transmit power of the terminal is limited by the defined terminal class. In increasing the terminal power cap for CA / DC, for a band combination where one band supports PC3 power class and the other supports PC2 power class, it is assumed that the total power associated with the band combination is the sum of the individual power classes.

[0178] Table 1

[0179] Among them, in one embodiment of the present disclosure, each frequency band combination introduces a new capability signaling, that is, signaling support for such power relaxation, and introduces a new maximum output power (MOP) terminal capability signaling higher power limit CADC (HigherPowerLimitCADC), which is applicable to UEs that support PC3 (23dBm) in one frequency band (Time-division Duplex (TDD) or Frequency-division Duplex (FDD)) and PC2 (26dBm) in another frequency band. With the new MOP capability, the UE can use the full power of the two PAs corresponding to the maximum composite power of 27.8 dBm for transmission, and in some embodiments, the total power of the terminal in CA or DC configuration can be limited to PC2 (26dBm), for example.

[0180] In one embodiment of the present disclosure, SAR / MPE requirements are crucial for enabling simultaneous transmission across multiple frequency bands. These requirements are based on regulatory constraints imposed on terminals when participating in uplink transmissions. Regulatory constraints on the total RF exposure experienced by users require terminals to determine safe transmit power levels for each frequency band. When a terminal approaches exceeding the permitted RF exposure level, the terminal can recalculate the maximum permitted transmit power for each frequency band in use, and uplink transmissions can see the change in transmit power (alternatively, the terminal can have a fixed limit on its transmit power so that it never exceeds the RF exposure limit). Because these operations are transparent to the gNB, they can affect the accuracy of the next generation Node B (gNB)'s perception of link quality, impact the results of link adaptation, and lead to fluctuations and losses in uplink throughput. A better understanding of these constraints and their impact on terminal behavior can help the gNB adopt more nuanced scheduling decisions.

[0181] Depending on the combination of frequency bands, for example, two types of RF exposure limits may be used. The first type uses a metric called the Specific Absorption Rate (SAR) and applies to frequency bands below 6 GHz, and the second type is called Power Density (PD) and applies to millimeter wave bands. Both indicators use a time-averaged approach to limit RF exposure, i.e., the RF exposure measured using these indicators and averaged over a specific time window must remain below a certain specified threshold. The regulations specify average RF exposure, not instantaneous RF exposure (there may be some exceptions in specific regions). This means that while it is not possible for a UE to transmit at full power all the time on all frequency bands, the terminal is able to transmit a higher total transmit power for a short period of time.

[0182] Among them, in one embodiment of the present disclosure, for the uplink duty cycle (UL duty cycle), in some embodiments, for example, the maximum maxUplinkDutyCycle (i.e., the maximum percentage of uplink symbols transmitted within an evaluation period, if the terminal exceeds this value, it exceeds the RF exposure limit) can be used, for example, to avoid the SAR problem in the non-CA case of HPUE (High power UE), but for the uplink CA multi-carrier case, for example, this problem can be avoided by terminal implementation. Figure 2A shows an example schematic diagram of terminal cumulative transmission power control. In some embodiments, the availability of a transmit power higher than 23dBm in a frequency band depends on the "percentage of uplink symbols transmitted within a certain evaluation period", that is, the exact duration of the evaluation period actually depends on the UE implementation and has not yet been specifically defined.

[0183] In some embodiments, the maximum transmit power for inter-band CA and inter-band EN-DC may be the sum of the maximum output power values ​​of the aggregated bands, again subject to similar conditions as those considered for the availability of transmit power above 23 dBm in the band (i.e., the average percentage of uplink symbols transmitted within a certain evaluation period).

[0184] Among them, in one embodiment of the present disclosure, for the power headroom report PHR, the UE can report the instantaneous transmit power used to send PUSCH transmission. The report consists of power headroom (6 bits), P CMAX,f,c The power headroom reflects the amount of additional transmit power that the UE can deliver with reference to the current PUSCH power level, while P CMAX,f,c The P-MPR reflects the maximum power that the UE can deliver in this situation. In some embodiments, for example, the P-MPR report may only be used for the FR2 band. Therefore, the PHR only provides a snapshot of a set of parameters for reporting a specific PUSCH transmission. Figures 2B and 2C illustrate two exemplary configurations of the PHR.

[0185] For example, in one embodiment of the present disclosure, with respect to the full power characteristics of the terminal, in some embodiments, uplink full power transmission supports the following three UE capabilities:

[0186] UE capability 1: The UE supports uplink full-power transmission, and the PA of each Tx chain supports full-power transmission;

[0187] UE capability 2: The UE supports uplink full-power transmission, and no Tx chain can transmit at full power.

[0188] UE capability 3: The UE supports uplink full-power transmission, and part of the Tx chain can support full-power transmission.

[0189] For example, in one embodiment of the present disclosure, a terminal may report its capabilities. The terminal's capability reporting may include, for example, reporting the terminal's ability to support full-power transmission, reporting the transmission mode, and reporting the TPMI that supports full-power transmission. Transmission modes include mode 0, mode 1, and mode 2.

[0190] In one embodiment of the present disclosure, for capability 1, for example, the following transmission schemes may be supported:

[0191] Regardless of the TPMI indicated by the base station, the PUSCH is transmitted at full power.

[0192] In one embodiment of the present disclosure, the following two transmission modes are introduced for capability 2 and capability 3:

[0193] In Mode 1, the gNB can configure the UE to transmit at full power using the following codebook subsets:

[0194] 2Tx non-coherent (NC)-codebook subset CBS:

[0195] Rank 1: TPMI = 0-2;

[0196] Rank 2: TPMI = 0.

[0197] 4Tx NC-CBS:

[0198] Rank 1: TPMI = 0-3, 13;

[0199] Rank 2: TPMI = 0-6;

[0200] Rank 3: TPMI = 0-1;

[0201] Rank 4: TPMI = 0.

[0202] 4Tx Partial-coherent (PC)-CBS:

[0203] Rank 1: TPMI=0-11, 12-15;

[0204] Rank 2: TPMI = 0-13;

[0205] Rank 3: TPMI = 0-2;

[0206] Rank 4: TPMI = 0-2.

[0207] In Mode 2, when the network device configures an SRS resource set with usage "codebook" for a terminal, a maximum of four SRS resources can be configured. If multiple SRS resources are configured, they can contain different numbers of SRS ports, but the number of corresponding space-related information cannot exceed two.

[0208] In one embodiment of the present disclosure, the terminal may report a set of transmit precoding matrix indicators (TPMIs) that can be transmitted at full power to the base station in the following manner:

[0209] For 2 ports,

[0210] Rank 1 supports {TPMI=0} and {TPMI=1};

[0211] Two bits are used in a bitmap format to indicate the TPMI that can be transmitted at full power.

[0212] For 4 ports,

[0213] Non-Coherent: 2 bits

[0214] Partial coherent: 4 bits

[0215] In one embodiment of the present disclosure, the TPMI group indication method of 4 ports may be as shown in Table 1, and the TPMI grouping method may be as shown in Table 2:

[0216] Table 1

[0217] Table 2

[0218] Among them, in one embodiment of the present disclosure, in some embodiments, uplink coverage has always been one of the bottlenecks of system performance, which will affect the signal quality and user experience. Operators, including operators, have a strong demand for uplink coverage enhancement.

[0219] For example, in one embodiment of the present disclosure, in the NR uplink CA&DC, the maximum transmit power defined on the band combination is limited by the terminal transmit power level defined on the BC. In some embodiments, for example, enhanced support is provided for high-power user equipment (HPUE) to better utilize the terminal's independent PA to achieve higher transmit power, mainly enhancing the PC2+PC3 configuration.

[0220] For example, in one embodiment of the present disclosure, when a terminal actually performs uplink transmission, it is subject to SAR / MPE requirements under FR1 / 2, and the actual transmit power will be limited. Transmit power adjustments based on SAR / MPE requirements may also cause large fluctuations or interruptions in transmit power, and are currently transparent to the base station. These power limitations, adjustments, and whether the HPUE can achieve high-power transmission have a significant impact on the correct scheduling of the base station, and will also directly affect the actual effect of enhancing the deployment of applications in the network in some embodiments. How to enable the base station to obtain power-related information of the terminal and correctly understand the terminal's corresponding decisions based on SAR will help the base station make better scheduling decisions.

[0221] For example, in one embodiment of the present disclosure, different processing mechanisms based on the terminal's possible exceeding of RF exposure limits can be studied. There are two possible processing mechanisms for the terminal, and the specific one to be adopted depends on the terminal implementation, which is not known by the network device.

[0222] The first processing mechanism: PC2 UE is allowed to indicate the maxUplinkDutyCycle of the PC2 power level at which it can maintain uplink transmission. For the FR1 frequency band, maxUplinkDutyCycle is indicated by the maxUplinkDutyCycle-PC2-FR1 parameter in the capability report. If this parameter is not reported by the terminal, it can be defaulted to 50%, for example. When the uplink scheduling actually configured or received by the terminal exceeds this RF exposure requirement, the terminal is allowed to fall back to transmitting as a PC3 terminal. That is, when the percentage of the number of uplink symbols transmitted by the terminal during the evaluation period is greater than maxUplinkDutyCycle, the terminal reduces the radiation by falling back on the power level to meet the radiation limit requirements.

[0223] The second handling mechanism: The terminal can use P-MPR (Power Management Maximum Power Reduction) fallback to resolve RF exposure or other issues. In FR1, for example, the terminal does not report P-MPR.

[0224] Based on different mechanisms, PHR reporting enhancements mainly include:

[0225] Report the terminal's power level or the change in power level;

[0226] Report the terminal's P-MPR; (FR1)

[0227] Other reported quantities are used to obtain power-related information of the terminal, such as the exact evaluation period of the terminal, the duration of the corresponding power level, etc., and can also be considered by updating and adjusting the configuration of the duty cycle.

[0228] For example, for the first processing mechanism: the power level change under the SAR mechanism can be reported to the base station through PHR, and the report information indicates the power fallback corresponding to the duty cycle exceeded. PowerClass This change supports the process changes of the terminal reducing PC and restoring PC.

[0229] For example, in one embodiment of the present disclosure, when the terminal actually performs uplink transmission, it is limited by the SAR requirements under FR1 / 2, and the actual maximum transmission power will be limited by the radiation requirements. The transmission power adjustment based on the SAR requirements may also cause large fluctuations in the transmission power or transmission interruption. Because the terminal power level fallback is transparent to the network, it is not conducive to the network equipment's understanding of the terminal power changes and subsequent scheduling decisions.

[0230] For example, in one embodiment of the present disclosure, it is possible to determine the power level fallback based on the SAR requirement by reporting ΔP via PHR. PowerClass , the terminal power level fallback may cause the terminal full power transmission mode / method to change, and may also have an impact on the power control mechanism, MIMO precoding transmission, etc. Therefore, how to implement the full power transmission mechanism after power level fallback is a problem that RAN1 needs to solve.

[0231] Specifically, regarding changes to the full-power support mode, for example, for a PC2 terminal implemented with a 2*PC3 PA, ul-FullPwrMode1 (mode 1) will be reported for PC2 to support full-power transmission. However, after falling back to PC, ul-FullPwrMode (mode 0) must be reported to achieve this. However, there are different ways for the terminal to implement mode 0 (each PA can support the current PC). If power saving is taken into account, it is generally supported by disabling some transmission channels. However, this terminal processing method affects the maximum number of MIMO layers that the terminal can support in the uplink. Therefore, it affects the selection of the TPMI table to which the MIMO precoding indicator TPMI corresponding to the codebook-based PUSCH transmission belongs.

[0232] For example, in one embodiment of the present disclosure, for the case where 4-port PUSCH transmission is configured as mode0 / mode2 or full power mode is not configured, different TPMI tables are used to allocate TPMIs suitable for this scheduling according to different max_Rank configurations. For example, it can be distinguished according to coherent transmission capabilities. Table 3 shows the precoding information and the number of layers. For 4 antenna ports, if the transform precoder is disabled, maxRank = 2 or 3 or 4, and ul FullPowerTransmission is not configured or configured as fullpowerMode2 or configured as fullpower; Table 4 shows the precoding information and the number of layers or the second precoding information. For 4 antenna ports, if the transform precoder is enabled and ul FullPowerTransmission is not configured or configured as fullpowerMode2 or configured as full power, or if transform precoding is disabled, maxRank = 1, ul FullPowerTransmission is not configured or configured as fullpowerMode2 or configured as full power.

[0233] Table 3

[0234] Table 4

[0235] For 4-port PUSCH transmission configured as mode0 mode 1, different TPMI tables are used to allocate TPMIs suitable for this scheduling according to different max_Rank configurations. Table 5 shows the precoding information and number of layers for 4 antenna ports. If the transform precoder is disabled, maxRank = 2, ul FullPowerTransmission = fullpowerMode1; Table 6 shows the precoding information and number of layers for 4 antenna ports. If the transform precoder is disabled, maxRank = 3 or 4, and ul FullPowerTransmission = fullpowerMode1; Table 7 shows the precoding information and number of layers or second precoding information for 4 antenna ports. If the transform precoder is enabled and ul FullPowerTransmission = fullpowerMode1, or if the transform precoder is disabled, maxRank = 1, ul FullPowerTransmission = fullpowerMode1.

[0238] Table 7

[0239] The following describes in detail a capability information reporting method, apparatus, device, and storage medium provided by embodiments of the present disclosure with reference to the accompanying drawings.

[0240] FIG3A is an interactive diagram of a capability information reporting method provided by an embodiment of the present disclosure. As shown in FIG3A , the method may include the following steps:

[0241] Step S3101: It is determined that a terminal power level fallback occurs, and the terminal reports a power headroom report (PHR) information to a network device, wherein the PHR information carries first indication information, and the first indication information is used to indicate the uplink full power transmission (UL FP Tx) mode information currently supported by the terminal;

[0242] In one embodiment of the present disclosure, a terminal may be capable of terminal power level fallback. This terminal does not specifically refer to a fixed terminal. For example, the terminal may be a PC2 terminal implemented with a 2xPC3 PA, or a PC1.5 terminal implemented with a 4xPC3 PA. This embodiment of the present disclosure is not limited to this. Terminal power level fallback may, for example, refer to a fallback of the terminal power level.

[0243] For example, in one embodiment of the present disclosure, the terminal of the present disclosure can be, for example, a PC2 terminal implemented with a 2*PC3 PA. To change the full power support mode, PC2 will report ul-FullPwrMode1(mode 1) to support full power transmission. However, after falling back to PC, ul-FullPwrMode(mode 0) must be reported to achieve this.

[0244] In one embodiment of the present disclosure, the terminal power level fallback of the present disclosure may be caused by SAR, for example, wherein different power levels may correspond to different maximum powers.

[0245] In one embodiment of the present disclosure, the first indication information refers to information used to indicate uplink full power transmission (UL FP Tx) mode information currently supported by the terminal. The first in the first indication information is only used to distinguish it from the remaining indication information. Different indication information can, for example, be used to indicate different MIMO terminal capability information.

[0246] For example, in one embodiment of the present disclosure, the purpose of uplink full power transmission (UL FP Tx) may be, for example, to increase the uplink transmission power supporting uplink MIMO terminals. The mode information may include, for example, FP mode mode0, FP mode mode1, and FP mode mode2. Mode0 may be, for example, ul-FullPwrMode, mode1 may be, for example, ul-FullPwrMode1, and mode2 may be, for example, ul-FullPwrMode2.

[0247] In one embodiment of the present disclosure, ul-FullPwrMode may be, for example, when a terminal is transmitting in a non-coherent codebook, if the total transmit power of the terminal is PC2, for example, 26dBm, then when the terminal is performing uplink dual-stream transmission, the transmit power is 23dBm+23dBm. If single-stream transmission is performed, the codebook is TPMI=0, TPMI=1, and the maximum transmit power is 23dBm.

[0248] In one embodiment of the present disclosure, ul-FullPwrMode1 may, for example, mean that when a terminal transmits a non-Coherent codebook, compared to ul-FullPwrMode, a codebook with TPMI = 2 is added during uplink single-stream transmission. For example, the same content may be transmitted simultaneously through two antenna ports with a power of 23dBm + 23dBm, which is a form of transmit diversity to enhance uplink performance.

[0249] Among them, in one embodiment of the present disclosure, ul-FullPwrMode2 is different from ul-FullPwrMode in that when the terminal is performing uplink single-stream transmission and the codebook is TPMI=0 or TPMI=1, the maximum transmit power can reach 26dBm.

[0256] For example, in one embodiment of the present disclosure, the first indication information is a bitmap of a first bit, and the bitmap of the first bit is used to indicate the third full power FP mode.

[0257] In one embodiment of the present disclosure, the first full-power FP mode, the second full-power FP mode, and the third full-power FP mode can be used to distinguish different full-power FP modes, and do not specifically refer to a fixed full-power FP mode. For example, the first full-power FP mode can be FP mode mode0, the second full-power FP mode can be FP mode mode1, and the third full-power FP mode can be FP mode mode2. For example, the first full-power FP mode can be FP mode mode1, the second full-power FP mode can be FP mode mode0, and the third full-power FP mode can be FP mode mode2. This embodiment of the present disclosure is not limited to this.

[0258] In one embodiment of the present disclosure, the first bit in the first bit can be used to distinguish it from the remaining bits. Different bits can correspond to different numbers of bits, or the same number of bits. For example, the number of bits corresponding to the first bit can be different from the number of bits corresponding to the other bits. The number of bits corresponding to the second bit can be the same as the number of bits corresponding to the third bit. The number of bits corresponding to the fourth bit can be the same as the number of bits corresponding to the fifth bit, or the same as the number of bits corresponding to the sixth bit. This embodiment of the present disclosure does not limit this.

[0377] FIG3B is an interactive diagram of a capability information reporting method provided by an embodiment of the present disclosure. In one embodiment of the present disclosure, the capability information reporting method shown in FIG3B is a parallel scheme to the capability information reporting method shown in FIG3A . For example, the embodiment shown in FIG3A can be executed separately from the embodiment shown in FIG3B . The difference between the capability information reporting method shown in FIG3A and the capability information reporting method shown in FIG3B can be, for example, that the terminal capability information indicated by the indication information is different.

[0378] As shown in FIG3B , the method may include the following steps:

[0379] Step S3201: It is determined that a terminal power level fallback occurs, and the terminal reports a power headroom report (PHR) to a network device, wherein the PHR carries second indication information, and the second indication information is used to indicate at least one of the following:

[0380] Antenna information corresponding to the current transmission mode of the terminal, where the terminal is the terminal corresponding to the current PUSCH power level PC;

[0383] In one embodiment of the present disclosure, the second indication information is used to indicate antenna information corresponding to the current transmission mode of the terminal, wherein the terminal is a terminal corresponding to the current power level PC of the PUSCH.

[0384] In one embodiment of the present disclosure, the second indication information is used to indicate antenna port information corresponding to the current transmission mode of the terminal, wherein the terminal is a terminal corresponding to the current power level PC of the PUSCH.

[0385] For example, in one embodiment of the present disclosure, the second indication information is used to indicate antenna information corresponding to the current transmission mode of the terminal corresponding to the current power level PC of the PUSCH.

[0386] For example, in one embodiment of the present disclosure, the second indication information is used to indicate antenna port information corresponding to the current transmission mode of the terminal corresponding to the current power level PC of the PUSCH.

[0387] In some embodiments of the present disclosure, the second indication information is used to indicate whether the terminal has reduced the use of the sending channel.

[0388] For example, in some embodiments of the present disclosure, the second indication information is used to indicate whether the terminal has turned off the use of some antennas.

[0389] In some embodiments of the present disclosure, the second indication information includes at least one bit, wherein the bit value corresponding to the at least one bit is a first bit value, which is used to indicate that the terminal has reduced the use of the sending channel, and the bit value corresponding to the at least one bit is a second bit value, which is used to indicate that the terminal has not reduced the use of the sending channel.

[0390] For example, in one embodiment of the present disclosure, the at least one bit may be one or more bits. The second indication information may include one bit, or multiple bits.

[0391] For example, in one embodiment of the present disclosure, the second indication information may include, for example, 1 bit, wherein when the bit value of 1 bit is the first bit value, it is used to indicate that the terminal has reduced the use of the sending channel; when the bit value of 1 bit is the second bit value, it is used to indicate that the terminal has not reduced the use of the sending channel.

[0393] For example, in one embodiment of the present disclosure, the first bit value may be 0, for example, indicating that the terminal does not reduce the use of the transmission channel. For example, the first bit value may be 0, for example, indicating that the Tx chain is in use.

[0394] In one embodiment of the present disclosure, the second indication information is used to indicate whether the terminal has shut down the use of some antennas, which may be applicable to 2Tx, for example.

[0395] Among them, in one embodiment of the present disclosure, the second indication information is used to indicate whether the terminal has turned off the use of some antennas. For example, it can be used for 4Tx, wherein 4Tx cannot accurately reflect the actual supported maximum RANK and coherence characteristic changes.

[0400] In one embodiment of the present disclosure, the second indication information is a bitmap, and the bitmap is used to indicate the usage of each antenna port of the terminal.

[0401] For example, in one embodiment of the present disclosure, for 2TX, if the bitmap Bitmap is "10", it can be said that the terminal implements the transmission corresponding to the current power level by turning off the second antenna. For example, when falling back from PC2 to PC3, a terminal with a PA structure of 23dBm+23dBm can achieve full power transmission through one PA. If the bitmap Bitmap is "11", it means that the terminal implements PC3 transmission through two PAs, namely 20dBm+20dBm; at the same time, the updated maxRank value and the corresponding TPMI table are determined through the indication information, so that the network device and the terminal have the same understanding after the number of MIMO layers actually supported by the terminal changes.

[0402] In one embodiment of the present disclosure, the method further includes:

[0404] The usage of each antenna of the terminal;

[0405] The usage of each antenna port of the terminal.

[0406] For example, in one embodiment of the present disclosure, it is determined that the terminal antenna is not turned off, and the usage status of each terminal antenna of the terminal is not reported.

[0407] For example, in one embodiment of the present disclosure, it is determined that the antenna port is not closed, and the usage of each antenna port of the terminal is not reported.

[0518] Update PUSCH configuration via RRC reconfiguration signaling;

[0519] PUSCH related configuration updates are performed through MAC-CE signaling.

[0525] FIG6A is a flow chart of a method for reporting capability information according to an embodiment of the present disclosure. As shown in FIG6A , the embodiment of the present disclosure relates to a method for reporting capability information, and the method includes:

[0526] In step S6101, the terminal may implement power backoff in different ways, and report the currently supported uplink full power transmission (UL full power Tx, UL FP Tx) mode information in the power headroom report (PHR).

[0527] In one embodiment of the present disclosure, a 3-bit bitmap may be used to indicate full power (FP) mode 0, FP mode 1, and FP mode 2, respectively.

[0528] In one embodiment of the present disclosure, a 4-bit bitmap may be used to indicate FP mode 0, FP mode 1, FP mode 2, and FP mode 1 / 2 respectively;

[0529] In one embodiment of the present disclosure, a 4-bit bitmap may be used to indicate FP mode 0, FP mode 1, FP mode 2, and a state where full power transmission cannot be achieved.

[0530] In one embodiment of the present disclosure, a 2-bit code point may be used to indicate the specific mode currently supported by the terminal. The specific code point design may be as follows:

[0531] Corresponding to "FP mode0", "FP mode1", "FP mode2"; or

[0532] Corresponding to "FP mode0", "FP mode1", "FP mode2", "FP mode1 / 2"; or

[0533] Corresponding to "FP mode0", "FP mode1", "FP mode2", and "unable to reach full power transmission".

[0534] In one embodiment of the present disclosure, the bandwidth / carrier reporting information corresponding to the PHR report is supplemented with antenna / antenna port information corresponding to the current transmission mode of the terminal corresponding to the current power class (PC).

[0535] In one embodiment of the present disclosure, for example, the terminal may be instructed whether to shut down the use of some antennas;

[0536] In one embodiment of the present disclosure, a 1-bit indication is used: for example, "1" indicates that some Tx chains are closed, and "0" indicates that all Tx chains are in use.

[0537] For example, in one embodiment of the present disclosure, the indication scheme is applicable to 2Tx

[0538] For example, in one embodiment of the present disclosure, it is impossible to accurately reflect the maximum RANK actually supported and the change in coherence characteristics for 4Tx, and therefore it is necessary to predefine the network fallback default max.RANK=1 scheduling.

[0539] Among them, in one embodiment of the present disclosure, the usage of each terminal antenna / antenna port can be indicated by a bitmap. For example, if 2TX indicates "10", it can be said that the terminal realizes the transmission corresponding to the current power level by turning off the second antenna. For example, PC2 falls back to PC3. For a terminal with a PA structure of 23+23dBm, full power transmission can be achieved through one PA. "11" can indicate that the terminal realizes PC3 transmission through two PAs, namely 20+20dBm; at the same time, the updated maxRank value and the corresponding transmit precoding matrix indicator (TPMI) table are determined through the indication information, so that the network device and the terminal have the same understanding after the number of multiple-in multipleout (MIMO) layers actually supported by the terminal changes.

[0540] In one embodiment of the present disclosure, for example, a function of indicating the usage of each terminal antenna / antenna port may be implemented through codepoint design; a code table may be predefined; and the code table may be, for example, as shown in Table 8 above.

[0541] In one embodiment of the present disclosure, for example, RANK adjustment information may be directly indicated:

[0542] 1 bit is used to indicate the maximum RANK adjustment direction supported;

[0543] Indicates the maximum number of RANK layers supported by 1 or 2 bits;

[0544] For example, in one embodiment of the present disclosure, a configuration update implementation method of the network device for the terminal reporting information may include:

[0545] In one embodiment of the present disclosure, this can be achieved through Radio Resource Control (RRC) reconfiguration, and reconfiguration and update can be performed on part of the signaling;

[0546] In one embodiment of the present disclosure, this can be achieved through Medium Access Control-Control Element (MAC CE) configuration.

[0547] For example, in one embodiment of the present disclosure, the configuration corresponding to the MIMO parameter can be updated by activating the configuration corresponding to the PC change, and the configuration of the parameter update corresponding to the operation of the PC recovery can be deactivated.

[0548] For example, in one embodiment of the present disclosure, each updated MIMO parameter may be indicated through MAC-CE.

[0549] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.
