[0035] In order to facilitate a clearer understanding of the various embodiments of the present application, some relevant background technical knowledge is first introduced as follows.

[0036] 1. Definition of Terminal Power Level

[0037] As telecommunications evolve towards the next generation and new use cases, 3GPP has added new terminal power classes. According to this definition, the UE terminal power class can be defined as the maximum transmit power over the New Radio (NR) channel bandwidth. Due to the low transmit (TX) power from the UE, the link budget is always uplink limited and the cell range is defined. When the UE power is high, it can make calls from a greater distance. 5G NR operates in both FR1 and FR2 frequency ranges, and 3GPP has defined terminal power classes for both.

[0038] (1) 3GPP Technical Specification (TS) 38.101-1 specifies terminal power classes for FR1, and 3GPP TS 38.101-2 specifies terminal power classes for FR2.

[0039] (2) In the FR1 frequency range, use wired measurements to specify the UE power level.

[0040] (3) For the FR2 frequency range, Over-The-Air (OTA) measurements are used to specify the UE power level.

[0041] For FR1, the UE power class (Power Class) is defined by Table 1.

[0042] Table 1. Definition of UE power classes

[0043]

[0044]

[0045] In the FR1 frequency band, when the terminal power level fallback condition is met, the terminal uses power level 3.

[0046] For FR2, 3GPP TS 38.101-2 specifies multiple power levels for terminals, namely power levels 1, 2, 3, 4, 5, 6 and 7. Each terminal power level corresponds to a specified usage scenario and application. Among them, power level 3 is the default power level.

[0047] Table 2 (Table 6.2.1.0-1 of 38.101-2). Terminal type assumptions

[0048]

[0049] For FR2 UE, the maximum equivalent isotropically radiated power (EIRP) limit is introduced to meet regulatory requirements, that is, to ensure that the device does not transmit high power that may cause health problems or generate excessive interference. The maximum EIRP takes into account the maximum antenna gain that the device can produce. For example, the maximum EIRP for power class 2 terminals is specified as 43 decibel milliwatts (dBm), while the maximum EIRP for power class 1 devices on most FR2 bands is specified as 55dBm.

[0050] In addition, the protocol also introduces minimum peak EIRP and total radiated power (TRP) requirements. Minimum peak EIRP is used to ensure that the device can produce at least the minimum output power in a specific direction. Total radiated power (TRP) is another requirement of UE, which defines the upper limit of the total radiated power in all directions.

[0051] 2. Power Class-Related UE Capabilities

[0052] The UE needs to report the power class capability and the maximum uplink duty cycle capability. For FR1, the UE can not report the power class only if it supports only the default power class.

[0053] 3. Power Headroom Report (PHR)

[0054] PHR, i.e. the difference between the uplink transmission power and the maximum transmission power of the UE, is reported to the base station (gNB), which helps the gNB to perform power control and resource scheduling for the UE uplink transmission. The Radio Resource Control (RRC) configures the timers phr-PeriodicTimer and phr-ProhibitTimer and the parameter phr-Tx-PowerFactorChange to control the PHR process.

[0055] The power headroom report (PHR) trigger conditions are as follows:

[0056] (a) When the UE has uplink resources to transmit new data, the phr-ProhibitTimer times out or has timed out, and the change in path loss since the last transmit power headroom report has exceeded the dB value of the configured phr-Tx-PowerFactorChange;

[0057] (b)phr-PeriodicTimer times out;

[0058] (c) When the RRC layer configures or reconfigures the PHR function or parameters, and such configuration or reconfiguration does not disable the PHR operation;

[0059] (d) Activate a Secondary Cell (SCell) with a configured uplink of any Medium Access Control (MAC) entity;

[0060] (e) Activate the Secondary Cell Group (SCG);

[0061] (f) Adding Primary SCG Cell (PSCell);

[0062] (g) When the UE has uplink resources to transmit new data, the phr-ProhibitTimer times out or has timed out, and the power backoff change corresponding to a certain uplink carrier exceeds the dB value of the configured phr-Tx-PowerFactorChange;

[0063] (h) When the active bandwidth part (BWP) of the SCell of any MAC entity with configured uplink switches from a dormant BWP to a non-dormant DL BWP;

[0064] (i) When the UE is configured with Maximum Permissible Exposure (MPE)-Reporting-FR2, the mpe-ProhibitTimer is not running, and the following conditions are met (the PHR report in this case is also called 'MPE P-MPR report'):

[0065] ii. the measured maximum allowed UE output Power Reduction (P-MPR) for meeting the FR2 MPE requirement as specified in TS 38.101-2

[15] is greater than or equal to the maximum allowed UE output Power Reduction threshold (mpr-threshold) of at least one activated FR2 serving unit since the last transmission of a PHR in this MAC entity; or

[0066] iii. The P-MPR measured for meeting FR2 MPE requirements as specified in TS 38.101-2

[15] has changed by more than phr-Tx-PowerFactorChange dB since the last transmission of a PHR for at least one activated FR2 service unit because the P-MPR measured for meeting MPE requirements is greater than or equal to the maximum allowed radiated emission threshold (mpe-threshold) in the MAC entity.

[0067] After the PHR is triggered, the MAC layer will generate a PHR MAC CE (single entry or multiple entries), and pack it into a Multi-Access PDU (MAC PDU) and send it to the physical layer. Then the MAC layer will start or restart the phr-PeriodicTimer and phr-ProhibitTimer, and cancel the triggered PHR. In other words, the MAC entity considers that the PHR trigger has been processed. If there is uplink transmission permission, the UE generates a PHR MAC CE. In the process of generating the MAC PDU, the UE packs the PHR MAC CE into the MAC PDU. The MAC PDU is sent to the physical layer, which performs channel coding and maps it to the Physical Uplink Shared Channel (PUSCH) for transmission. When the gNB receives this MAC PDU, it separates the PHR MAC CE from the MAC PDU.

[0068] Power headroom (PH) is the difference between the maximum transmission power allowed by the terminal (UE) and the currently evaluated PUSCH transmission power. It indicates how much transmission power the UE can use in addition to the transmission power used for the current PUSCH transmission. The network side device selects the number of scheduled time-frequency blocks and the modulation format according to the power headroom reported by the UE. The power headroom (PH) is divided into real value (real PH) and virtual value (virtual PH). The real value is calculated based on the transmission parameters actually allocated by the network side device, such as physical resources and power compensation factors; while the virtual value is the power headroom calculated based on the predefined transmission parameters. In the existing specifications, if the UE triggers the PHR report and meets the sending conditions, the UE needs to send the PHR in the format of MAC CE (control element). Whether the real PH or virtual PH is sent on each component carrier (CC) / cell depends on the following factors. Hereinafter, the PUSCH carrying PHR is called PUSCH with PHR, and the CC where the PUSCH with PHR is located is called PHR CC.

[0069] 1) Whether there is PUSCH transmission on other activated CCs, and whether the time domain resources occupied by its PUSCH and the PUSCH with PHR transmitted on the PHR CC overlap; if there is no overlap, the PH for the activated CC is virtualPH or no PH is sent;

[0070] 2) Whether the PH is for a configured grant (CG) or a dynamic grant (DG) PUSCH;

[0071] 3) Determine the time (T-calculate) to calculate PH. If relevant scheduling information is obtained between the PHR trigger time T-trigger and T-calculate, it is real PH; otherwise, virtual PH is reported;

[0072] 3-1) If the PHR is transmitted on the DG PUSCH, the T-calculate is the time when the UL grant is received;

[0073] 3-2) If PHR is transmitted on CG PUSCH, T-calculate is the time at which the start symbol of CG PUSCH is sent minus T′ proc,2 , where T′ proc,2 =T proc,2 , T proc,2The PUSCH preparation time is defined in TS 38.214, and its value depends on the terminal's ability to process data.

[0074] Figure 2 This is a schematic diagram of PHR transmission on DG PUSCH provided by the prior art. Cell 4 is a deactivated CC and there is no PH for Cell 4. The PUSCH of Cell 5 does not have temporal resource overlap with the PUSCH with PHR, so there is no PHR for Cell 5. There are only PHRs for Real PH for Cell 1, Real PH for Cell 2, and Virtual PH for Cell 3.

[0075] Figure 3 It is a schematic diagram of the transmission of PHR on CG PUSCH provided by the prior art, wherein the UE determines whether the PH of CGPUSCH on Cell 2 is Real PH or Virtual PH, and the PUSCH of Cell 4 has no time resource overlap with the PUSCH with PHR, therefore, there is no PHR of Cell 4.

[0076] PHR is transmitted on the Medium Access Control (MAC)-Control Element (CE). Figure 4 is a schematic diagram of the format of a multi-entity PHR MAC CE provided by the prior art, such as Figure 4 As shown, where:

In addition, for type 1, type 2, and type 3 PH, setting the V field to 0 indicates the presence of an associated PUSCH. CMAX ,f,c fields, and setting the V field to 1 indicates that the associated octet P is included. CMAX,f,c Field is omitted.

If mpe-Reporting-FR2 is not configured, or if the serving cell operates on FR1, or if the P field is set to 0, the R bit is present instead.

[0087] 4. Definition and Reporting of Power Level Excursion

[0088] For FR1, the UE can set a maximum output power configured by the UE. The protocol specifies the upper and lower limits of the maximum output power configured by the UE, one of which is the offset ΔP of the power class. PowerClass .

[0089] In NR Rel-18, RAN4 determined the support for UE power level offset ΔP PowerClass Report.

[0090] 5. UE full power capability reporting and configuration

[0091] Starting from 3GPP Rel-16, NR introduced the UE UL full power mode for uplink transmission. The network configures the signaling based on the UL full power mode capability reported by the UE to indicate which UL full power mode the UE should use. There are three uplink full power modes in total, and different uplink full power modes will affect the UE's determination of uplink precoding information and the number of layers.

[0092] The following describes in detail the method for reporting power level related information provided by the embodiment of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.

[0093] The method for reporting power level related information provided in the embodiment of the present application can be applied to the scenario of reporting power level related information of the terminal. The power level related information is determined by the terminal. When a first condition is met, since the first condition is the trigger condition for reporting power level related information, the terminal can report power level related information to the network side device in a timely manner, thereby realizing timely reporting of power level related information.

[0094] Figure 5 is a flow chart of a method for reporting power level related information provided in an embodiment of the present application, such as Figure 5 As shown, the method includes steps 501 and 502; wherein:

[0095] Step 501, the terminal determines power level related information;

[0096] Step 502: When a first condition is satisfied, the terminal reports the power level related information to a network side device; the first condition is a trigger condition for reporting the power level related information.

[0097] It should be noted that the embodiments of the present application can be applied to the scenario of reporting power level related information of the terminal, and the terminal and the network side device include but are not limited to the types of the terminal 11 and the network side device 12 listed above, and the embodiments of the present application are not limited to this. The terminal has the ability to report power level related information, and the network side device supports the power level related information function.

[0098] Specifically, the first condition is a trigger condition for reporting power class related information, and the power class related information includes at least one of the following: power class offset (Delta Power Class, DPC); uplink full power transmission capability corresponding to the power class. The power class offset can also be called Delta PC (ΔP PowerClass ) or DPC.

[0099] Optionally, the DPC includes at least one of the following:

[0100] (1) First indication information, used to indicate the value of the DPC; the first indication information is bit information of a preset length.

[0101] Specifically, the value of DPC can be ΔP defined by the existing protocol. PowerClassThe possible values ​​in the DPC, or the value of the DPC can be a set of values, and the step size of the set of values ​​may not be equal to 3dB. In this case, the value of the DPC can be allowed to be less than the maximum power corresponding to the actual power class, thereby improving the configuration flexibility of the DPC. The first indication information is bit information of a preset length. For example, the first indication information is a 2-bit field or a 3-bit field. When the first indication information is a 2-bit field, {00, 01, 10, 11} can be used to indicate the corresponding values ​​in {0dB, 3dB, 6dB, reserved} respectively; when the first indication information is a 3-bit field, {000, 001, 010, 011, 100, 101, 110, 111} can be used to indicate the corresponding values ​​in {0dB, 2dB, 3dB, 4dB, 6dB, 8dB, 9dB, reserved} respectively.

[0102] (2) Second indication information, used to indicate whether the power level of the terminal is to be rolled back.

[0103] Specifically, the second indication information is a flag used to indicate whether the power level of the terminal is backed off. In this case, the specific backoff number of dB does not need to be indicated, which can save signaling overhead. For example, one bit is used to indicate that bit 0 indicates that there is no power level backoff, and bit 1 indicates that there is a power level backoff. Alternatively, 2 bits are used to indicate, but the specific backoff number of dB is not indicated. For example, {00, 01, 10, 11} respectively indicate the corresponding values ​​in {no power level backoff, power level backoff, power level increase, reserved}. Alternatively, 1 bit is used to indicate that bit 0 indicates that there is a power level backoff, and bit 1 indicates that there is a power level increase.

[0104] Optionally, the reporting of the uplink full power UL full power transmission capability corresponding to the power class power class includes any one of the following:

[0105] (a) The terminal reports the UL full power transmission capability corresponding to all supported power classes.

[0106] Specifically, for terminals that support DPC reporting, the terminals can report the UL full power transmission capabilities corresponding to all supported power classes, so that the network side equipment knows the UL full power transmission capabilities corresponding to different power classes, and can configure different UL full power modes for the terminals.

[0107] For example, the terminal can independently report the UL full power transmission capability for each (per) power class. The UL full power mode corresponding to different power classes can be configured independently.

[0108] (b) The terminal reports the UL full power transmission capability together with the DPC.

[0109] Specifically, for a terminal supporting DPC reporting, the terminal can report the UL full power transmission capability together with the DPC, thereby saving resource overhead. For example, the terminal can dynamically report the UL full power mode corresponding to the fallback power level.

[0110] The terminal may determine the power level related information, and when the first condition is met, the terminal may report the power level related information to the network side device.

[0111] The method for reporting power level related information provided in the embodiment of the present application determines the power level related information through the terminal. When a first condition is met, since the first condition is a trigger condition for reporting the power level related information, the terminal can promptly report the power level related information to the network side device, thereby realizing timely reporting of the power level related information.

[0112] Optionally, the first condition includes at least one of the following:

[0113] 1) Triggering conditions for power headroom report (PHR).

[0114] Specifically, the triggering condition for DPC reporting is the triggering condition for PHR, the terminal has the ability to report DPC, and the network side device supports the DPC function. For example, the network side device configures the DPC available (enable) / unavailable (disable) parameter to determine whether DPC reporting is supported. When the terminal supports the DPC reporting function and the conditions for triggering PHR reporting are met, the terminal reports the DPC to the network side device, and the DPC is the DPC used for the uplink transmission of sending PHR.

[0115] 2) The power level offset DPC used in the current uplink transmission is different from the reference DPC.

[0116] Specifically, the DPC reporting depends on the difference between the DPC used in the current uplink transmission and the reference DPC, that is, the change of the DPC used in the current uplink transmission.

[0117] Optionally, the reference DPC includes any of the following:

[0118] a) The DPC used for the last uplink transmission;

[0119] b) DPC corresponding to the previous multiple uplink transmissions.

[0120] 3) The difference between the DPC used for the current uplink transmission and the reference DPC is greater than or equal to the first threshold.

[0121] Specifically, when the difference between the DPC used in the current uplink transmission and the reference DPC is greater than or equal to the first threshold, the terminal reports the DPC to the network side device, that is, when the difference between the DPC used in the current uplink transmission and the reference DPC is greater than the first threshold, the terminal can report the DPC to the network side device; or, when the difference between the DPC used in the current uplink transmission and the reference DPC is equal to the first threshold, the terminal can also report the DPC to the network side device. The first threshold can be predefined by network configuration or protocol.

[0122] For example, the first threshold is 3 dB, and when the difference between the DPC used for the current uplink transmission and the reference DPC is greater than or equal to 3 dB, the terminal reports the DPC to the network-side device.

[0123] 4) The difference between the DPC used for the current uplink transmission and the reference DPC is less than or equal to the second threshold.

[0124] Specifically, when the difference between the DPC used for the current uplink transmission and the reference DPC is less than or equal to the second threshold, the terminal reports the DPC to the network side device, that is, when the difference between the DPC used for the current uplink transmission and the reference DPC is less than the second threshold, the terminal can report the DPC to the network side device; or, when the difference between the DPC used for the current uplink transmission and the reference DPC is equal to the second threshold, the terminal can also report the DPC to the network side device. The second threshold can be predefined by network configuration or protocol. The first threshold and the second threshold can be the same or different.

[0125] For example, the second threshold is 6 dB, and when the difference between the DPC used for the current uplink transmission and the reference DPC is less than or equal to 6 dB, the terminal reports the DPC to the network-side device.

[0126] 5) The actual power class Power Class of the terminal is different from the reference Power Class.

[0127] Specifically, DPC reporting depends on the difference between the actual power class of the terminal and the reference power class, that is, the actual power class of the terminal changes. For example, when the actual power class of the terminal changes, the terminal reports DPC to the network side device.

[0128] 6) The actual Power Class of the terminal is different from the reference Power Class, and the timer corresponding to the Power Class of the terminal times out.

[0129] Specifically, when there is a difference between the actual Power Class of the terminal and the reference Power Class, and when the timer corresponding to the PowerClass of the terminal times out, the terminal reports the DPC to the network side device, that is, the actual Power Class of the terminal changes, and the DPC is reported only after the timer corresponding to the Power Class of the terminal times out. The timer corresponding to the Power Class may be a DPC timer (delta_power_class_timer). When the actual Power Class of the terminal changes, the DPC timer is started. After the DPC timer times out, the terminal reports the DPC to the network side device. The duration of the timer may be predefined by the network configuration or protocol.

[0130] 7) The DPC used for the current uplink transmission is greater than or equal to the third threshold.

[0131] Specifically, DPC reporting depends on whether the DPC used in the current uplink transmission is greater than or equal to a third threshold, that is, it depends on the size of the DPC. The third threshold may be predefined by the network configuration or protocol. When the DPC used in the current uplink transmission is greater than the third threshold, the terminal may report the DPC to the network side device; or, when the DPC used in the current uplink transmission is equal to the third threshold, the terminal may also report the DPC to the network side device.

[0132] For example, the third threshold is 3 dB, and the terminal reports the DPC to the network-side device only when the DPC used for the current uplink transmission is greater than or equal to 3 dB.

[0133] 8) The DPC used for the current uplink transmission is less than or equal to the fourth threshold.

[0134] Specifically, when the DPC used for the current uplink transmission is less than or equal to the fourth threshold, the terminal reports the DPC to the network side device, that is, when the DPC used for the current uplink transmission is less than the fourth threshold, the terminal can report the DPC to the network side device; or, when the DPC used for the current uplink transmission is equal to the fourth threshold, the terminal can also report the DPC to the network side device. The fourth threshold can be predefined by network configuration or protocol. The third threshold and the fourth threshold can be the same or different.

[0135] For example, the fourth threshold is 8 dB, and the terminal reports the DPC to the network-side device only when the DPC used for the current uplink transmission is less than or equal to 8 dB.

[0136] 9) The uplink beam used for the current uplink transmission is different from the uplink beam used for the last uplink transmission or the previous multiple uplink transmissions.

[0137] Specifically, the DPC report depends on the difference between the uplink beam used in the current uplink transmission and the uplink beam used in the last uplink transmission or in the previous multiple uplink transmissions, that is, the change of the uplink beam.

[0138] The change of the uplink beam may be the difference between the uplink beam used for the current uplink transmission and the uplink beam used for the last uplink transmission. For example, when the uplink beam used for the current PUSCH transmission changes relative to the beam used for the last uplink transmission, the terminal needs to report the DPC used for the current uplink transmission to the network side device.

[0139] The change of the uplink beam may also be the difference between the uplink beam used for the current uplink transmission and the uplink beam used for the previous multiple uplink transmissions. For example, when the uplink beam used for the current PUSCH transmission changes relative to the beam used for the previous multiple uplink transmissions, the terminal needs to report the DPC used for the current uplink transmission to the network side device.

[0140] 10) A transmission interval between a current uplink transmission and a previous uplink transmission is greater than or equal to a fifth threshold.

[0141] It should be noted that when the terminal uplink transmission is not very frequent, the difference between the DPC used for the current uplink transmission and the DPC used for the last uplink transmission does not necessarily need to be kept in the network side device or terminal. At this time, the terminal can be required to report the latest DPC.

[0142] Specifically, when the transmission interval between the current uplink transmission and the last uplink transmission is greater than or equal to the fifth threshold, the terminal reports the DPC to the network side device, that is, when the transmission interval between the current uplink transmission and the last uplink transmission is greater than the fifth threshold, the terminal can report the DPC to the network side device; or, when the transmission interval between the current uplink transmission and the last uplink transmission is equal to the fifth threshold, the terminal can also report the DPC to the network side device. The fifth threshold can be predefined by network configuration or protocol.

[0143] 11) A transmission interval between a current uplink transmission and a previous uplink transmission is less than or equal to a sixth threshold.

[0144] Specifically, when the transmission interval between the current uplink transmission and the last uplink transmission is less than or equal to the sixth threshold, the terminal reports the DPC to the network side device, that is, when the transmission interval between the current uplink transmission and the last uplink transmission is less than the sixth threshold, the terminal can report the DPC to the network side device; or, when the transmission interval between the current uplink transmission and the last uplink transmission is equal to the sixth threshold, the terminal can also report the DPC to the network side device. The sixth threshold can be predefined by network configuration or protocol. The fifth threshold and the sixth threshold can be the same or different.

[0145] The method for reporting power level related information provided in the embodiment of the present application enables the terminal to adaptively report power level related information to the network side device and adjust the necessity of power level related information based on the first condition, thereby improving the flexibility of reporting power level related information.

[0146] Optionally, the last uplink transmission or the previous multiple uplink transmissions are determined based on a first time window; the length of the first time window is predefined by network configuration or protocol.

[0147] Specifically, the deadline of the first time window is the time of the last uplink transmission, that is, the last symbol of the last transmission, and the start time of the first time window is determined by calculating the length of the first time window and the deadline of the first time window. The length of the first time window can be predefined by network configuration or protocol.

[0148] For example, the DPC used for the last uplink transmission can be determined by the DPC used for the first or last uplink transmission in the first time window, and the DPC corresponding to the previous multiple uplink transmissions can be determined by the maximum, minimum or average value of the DPC used for all uplink transmissions in the first time window.

[0149] Optionally, the first time window is associated with a second time window; the second time window includes at least one of the following:

[0150] (a) PHR reporting cycle;

[0151] (b) Synchronization Signal Block (SSB) period;

[0152] (c) Channel State Information-Reference Signal (CSI-RS) period;

[0153] (d) Sounding Reference Signal (SRS) period;

[0154] (e) SSB to Physical Random Access Channel (PRACH) occasion association period;

[0155] (f) SSB to PRACH occasion association mode period;

[0156] (g) The CG period corresponding to the physical uplink shared channel PUSCH scheduled by the configured grant (CG).

[0157] Optionally, the DPCs corresponding to the previous multiple uplink transmissions may be determined based on all DPCs of the previous multiple uplink transmissions.

[0158] Optionally, the DPC corresponding to the previous multiple uplink transmissions includes any one of the following items: an average value of all DPCs of the previous multiple uplink transmissions; a weighted average value of all DPCs of the previous multiple uplink transmissions; a median value of all DPCs of the previous multiple uplink transmissions.

[0159] Specifically, when determining the weighted average value of all DPCs of the previous multiple uplink transmissions, the weight may be determined by the time interval between all DPCs of the previous multiple uplink transmissions and the DPC used for the current uplink transmission.

[0160] Optionally, when the current uplink transmission is the first uplink transmission, the terminal determines that a DPC used by the current uplink transmission is different from a reference DPC based on at least one of the following:

[0161] (1) Preset value: Specifically, the difference between the DPC used in the current uplink transmission and the reference DPC is used to determine whether to report the DPC. When the current uplink transmission is the first uplink transmission, a preset value may be preset as the difference between the DPC used in the current uplink transmission and the reference DPC. For example, the preset value is 0, that is, assuming that the DPC used in the previous uplink transmission is the same as the DPC used in the current uplink transmission, the difference between the DPC used in the current uplink transmission and the reference DPC is 0.

[0162] (2) The DPC used for the current uplink transmission: Specifically, the difference between the DPC used for the current uplink transmission and the reference DPC is the DPC used for the current uplink transmission, that is, the reference DPC is 0.

[0163] (3) Predefined by network configuration or protocol.

[0164] Optionally, the current uplink transmission and the last uplink transmission satisfy at least one of the following:

[0165] 1) The same uplink transmission channel.

[0166] Specifically, the current uplink transmission and the last uplink transmission are the same uplink transmission channel. For example, when the current uplink transmission channel corresponding to the DPC used by the current uplink transmission is PUSCH transmission, the uplink transmission corresponding to the DPC used by the last uplink transmission used to calculate the DPC change must also be PUSCH transmission.

[0167] 2) Different uplink transmission channels.

[0168] Specifically, the current uplink transmission and the last uplink transmission are different uplink transmission channels. For example, when the uplink transmission channel corresponding to the DPC used by the current uplink transmission is PUSCH transmission, the uplink transmission corresponding to the DPC used by the last uplink transmission for calculating the DPC change may also be non-PUSCH transmission, such as SRS transmission.

[0169] 3) Uplink transmission on the same carrier frequency.

[0170] Specifically, the current uplink transmission and the last uplink transmission are uplink transmissions on the same carrier frequency. For example, the uplink transmission corresponding to the DPC used in the current uplink transmission is on carrier frequency CC1, and the uplink transmission corresponding to the DPC used in the last uplink transmission used to calculate the DPC change must also be on carrier frequency CC1.

[0171] 4) Uplink transmission in the same cell.

[0172] Specifically, the current uplink transmission and the previous uplink transmission are uplink transmissions on the same cell.

[0173] 5) Same uplink beam.

[0174] Specifically, the current uplink transmission and the last uplink transmission are the same uplink beam. For example, when the current uplink transmission channel corresponding to the DPC used in the current uplink transmission is PUSCH transmission, the uplink transmission corresponding to the DPC used in the last uplink transmission for calculating the DPC change and the current PUSCH transmission use the same spatial domain transmission filter, that is, the same uplink beam.

[0175] Optionally, when the network side device learns the actual assumed DPC used by the terminal, the terminal cancels reporting the power level related information to the network side device.

[0176] Specifically, in some special scenarios, the network side device learns the actual assumed DPC used by the terminal. In the case where the network side device learns the actual assumed DPC used by the terminal, the DPC is a fixed value, and the terminal can cancel reporting power level related information to the network side device, that is, the terminal can not report power level related information to the network side device, thereby reducing signaling overhead.

[0177] Optionally, the actual assumed DPC used by the terminal learned by the network side device includes at least one of the following:

[0178] a) The terminal is configured with a supplementary uplink (SUL), and the requirement of the default power level of the terminal is applied to the frequency band of the power level indicated by the terminal.

[0179] Specifically, when the terminal is configured with SUL and the default power level requirement of the terminal is applied to the frequency band of the terminal indicated power level according to the provisions of Section 6.2C.1 of Protocol 38.101-1, the terminal can cancel reporting power level related information to the network side device.

[0180] b) A terminal with power level PC2 function with transmit diversity txDiversity-r16 function or a terminal with PC1.5 function indicates the SRS transmit channel switching TxSwitch function, and uses the SRS transmission occasion set to antenna switching in the SRS resource set. The SRS resources configured in each SRS resource set consist of one SRS port.

[0181] Specifically, a terminal with a PC2 function and a txDiversity-r16 function or a terminal with a PC1.5 function indicates an SRS TxSwitch function ('t1r2' or 't1r4' or 't1r1-t1r2' or 't1r1-t1r2-t1r2-t1r4'), and when an SRS transmission setting for antenna switching is used in an SRS resource set, and the SRS resources configured in each SRS resource set are composed of one SRS port, the terminal can cancel reporting power level related information to the network side device.

[0182] c) The maximum power P-max indicated by the terminal with PC2 function is less than or equal to the seventh threshold.

[0183] Specifically, when the P-max indicated by the terminal with PC2 function is less than or equal to the seventh threshold, the terminal can cancel reporting power level related information to the network side device. For example, when the seventh threshold is 23dB, and the P-max indicated by the terminal with PC2 function is less than or equal to 23dBm, the terminal can cancel reporting power level related information to the network side device.

[0184] d) The maximum power P-max indicated by the terminal with PC1.5 function is less than or equal to the eighth threshold.

[0185] Specifically, if the P-max indicated by the terminal with PC1.5 function is less than or equal to the eighth threshold, the terminal can cancel reporting the power level related information to the network side device. For example, if the seventh threshold is 26dB, and the P-max indicated by the terminal with PC1.5 function is less than or equal to 26dB, the terminal can cancel reporting the power level related information to the network side device.

[0186] Optionally, reporting the power level related information to the network side device includes any one of the following:

[0187] (1) reporting the power level related information to the network side device through a first media access control MAC-control unit CE; the first media access control MAC-control unit CE is a MAC-CE that does not report PHR.

[0188] Specifically, the first MAC-CE is a MAC-CE that does not report PHR, that is, the first MAC-CE is an additionally defined MAC-CE. The terminal reports the power level related information to the network side device through the first MAC-CE.

[0189] When the power level related information is DPC, the DPC is reported in the first MAC-CE, and the DPC is identified by a new logical channel identity (Logical Channel Identity, LCID) or an extended logical channel identity (extended Logical Channel Identity, eLCID).

[0190] For example, a DPC field is introduced in a first MAC-CE, which is located at the 2 least significant bits (LSB) of a byte, such as Figure 6 As shown, Figure 6 This is a schematic diagram of the format of the first MAC-CE provided in an embodiment of the present application.

[0191] (2) reporting the power level related information to the network side device through a second MAC-CE; the second MAC-CE is a MAC-CE for reporting PHR.

[0192] Specifically, the second MAC-CE is a MAC-CE for reporting PHR, that is, the second MAC-CE is an existing MAC-CE, which is implemented by modifying the definition of relevant fields. The terminal reports power level related information to the network side device through the second MAC-CE.

[0193] When the power level related information is DPC, the DPC is reported in the second MAC-CE, and the reporting of the DPC is achieved by modifying the definition of related fields.

[0194] For example, a 2-bit DPC field is introduced in the second MAC-CE of the legacy PHR, which is located at the first 2 most significant bits (MSB) of the second byte, such as Figure 7 As shown, Figure 7 This is one of the schematic diagrams of the format of the second MAC-CE provided in an embodiment of the present application.

[0195] For example, a 1-bit DPC field is introduced in the second MAC-CE of the legacy PHR, located in the second bit of the first byte, such as Figure 8 As shown, Figure 8 This is the second schematic diagram of the format of the second MAC-CE provided in the embodiment of the present application.

[0196] (3) Reporting the power level related information to the network side device in the form of one DPC for each beam or each beam group.

[0197] Specifically, the terminal reports the power level related information to the network side device in the form of one DPC for each beam or each beam group. When the power level related information is DPC, the DPC is reported to the network side device in the form of one DPC for each beam or each beam group.

[0198] For example, DPC reporting is independent reporting for each beam, such as Fig. 9 As shown, Fig. 9 This is one of the schematic diagrams of reporting DPC according to each beam provided in the embodiment of the present application. m Indicates the DPC value corresponding to the mth reported DPC beam, C i Indicates whether the DPC corresponding to SSB i is reported.

[0199] For example, DPC is reported per beam and is reported together with legacy PHR, such as Fig.10 As shown, Fig.10 This is the second schematic diagram of reporting DPC according to each beam provided in the embodiment of the present application. m Indicates the DPC value corresponding to the mth reported DPC beam, C i Indicates whether the DPC corresponding to SSB i is reported.

[0200] (4) reporting the power level related information to the network side device in the form of each serving cell or each serving cell group corresponding to one DPC.

[0201] Specifically, the power level related information is reported to the network side device in the form of one DPC for each serving cell or each serving cell group. When the power level related information is DPC, the DPC is reported to the network side device in the form of one DPC for each serving cell or each serving cell group.

[0202] For example, DPC reporting is independent reporting for each serving cell. Fig. 9 The diagram shown is the same as the diagram of DPC reported by each beam. m Indicates the DPC value corresponding to the serving cell reporting the mth DPC, C i Indicates whether the DPC corresponding to serving cell i is reported.

[0203] For example, DPC is reported by each serving cell and reported together with legacy PHR. Fig.10 The diagram shown is the same as the diagram of DPC reported by each beam. m Indicates the DPC value corresponding to the serving cell reporting the mth DPC, C i Indicates whether the DPC corresponding to serving cell i is reported.

[0204] In an embodiment of the present application, the terminal reports power level-related information to the network side device through the first MAC-CE, the second MAC-CE, in the form of one DPC for each beam or each beam group, or in the form of one DPC for each serving cell or each serving cell group, thereby reducing the signaling overhead of reporting and improving the flexibility of reporting, so that the network side device can flexibly adjust the resource scheduling of the terminal according to the power level-related information reported by the terminal.

[0205] Optionally, the serving cell group satisfies at least one of the following:

[0206] a) All intra-band serving cells in the frequency band are regarded as a group of serving cells;

[0207] b) All intra-frequency serving cells are regarded as a group of serving cells;

[0208] c) Predefined by network configuration or protocol.

[0209] Specifically, all serving cells are numbered according to serving cell IDs, the size of a group is defined, thereby determining the number of groups, and the serving cells in each serving cell group are determined in the order of cell IDs.

[0210] Optionally, the reporting of the DPC includes periodic reporting or non-periodic reporting.

[0211] For example, when the network side device configures the terminal to be in a preset period, the terminal can report the DPC as long as the first condition is met.

[0212] Optionally, the non-periodic reporting satisfies at least one of the following:

[0213] 1) Downlink Control Information (DCI) activation or indication;

[0214] 2) MAC-CE activation or indication;

[0215] 3) Timer triggering. For example, when reporting DPC, the timer is started. If the timer is closed, the DPC is reported when the timer is started again.

[0216] For example, when the network-side device enables DPC reporting, and the terminal has the DPC reporting capability, and the first condition is met, the terminal reports DPC non-periodically (dynamically). The network-side device can introduce a bit in the DCI for scheduling uplink transmission to indicate whether to report DPC. Alternatively, the network-side device indicates DPC reporting in MAC-CE, and the terminal can indicate the DPC to be used in the first uplink transmission after MAC-CE.

[0217] Optionally, after reporting the DPC, the terminal determines an effective time of a new power level.

[0218] It should be noted that the full power capability of the terminal may be different for terminals of different power classes. In this case, the relationship between the full power capability of the terminal and the power level of the terminal needs to be considered. In order to enable the network-side device to know the UL full power mode corresponding to different power classes, so that different UL full power modes can be configured for the terminal, and the network-side device and the terminal can have the same assumptions about the precoding information and the number of layers used for uplink transmission, the network-side device and the terminal need to have a unified understanding of the effective time of DPC. After the DPC is reported or the new power class assumption takes effect, the terminal needs to determine the UL full power mode corresponding to the new power class.

[0219] Specifically, the new power level includes a rolled-back power level, an increased power level, or a restored power level. After reporting the DPC, the terminal may determine the effective time of the new power level.

[0220] In an embodiment of the present application, after reporting the DPC, the terminal determines the effective time of the new power level, so that the network side device can configure the uplink full power mode corresponding to the new power level for the terminal, thereby achieving flexible adjustment of the resource scheduling of the terminal, so that the terminal uses the corresponding uplink full power mode, and the network side device and the terminal have the same assumptions about the precoding information and the number of layers used for uplink transmission.

[0221] Optionally, determining the effective time of the new power level includes at least one of the following:

[0222] (1) Determine the effective time of the new power level through time offset.

[0223] Specifically, after the PUSCH reporting the DPC is sent, a time offset is introduced, and the effective time of the new power level is determined by the time offset.

[0224] Optionally, the time offset is determined by network configuration (for example, in units of slots or symbols), protocol pre-definition or target factors; the target factors include PUSCH processing time or MAC processing time.

[0225] (2) Determine the effective time of the new power level through network activation or indication.

[0226] Specifically, after the terminal reports the DPC, it can determine the effective time of the new power level through network activation or indication. For example, after the DPC is reported, the network side device indicates whether to use the new power level through MAC-CE or DCI, which can determine the effective time of the new power level, so as to use the UL full power mode corresponding to the new power level.

[0227] (3) Determine the effective time of the new power level through network deactivation or indication.

[0228] Specifically, after the terminal reports the DPC, it can determine the effective time of the new power level through network deactivation or indication. For example, after the DPC is reported, after the network-side device activates the new power level through MAC-CE, the network-side device can also indicate through another MAC-CE or DCI that the new power level is invalid, that is, the terminal needs to use the restored power level, and can determine the effective time of the restored power class, so as to use the UL full power mode corresponding to the restored power class.

[0229] (4) The effective time of the new power level is determined by the time of the first uplink transmission after the uplink transmission carrying the DPC.

[0230] Specifically, after reporting the DPC, the terminal can determine the effective time of the new power level by the time of the first uplink transmission after the uplink transmission carrying the DPC. The new power level is not applicable to the PUSCH transmission scheduled by the DCI received by the terminal before the PUSCH transmission carrying the DPC.

[0231] (5) For the same hybrid automatic repeat request HARQ process, the effective time of the new power level is determined by scheduling the uplink transmission time corresponding to the PUSCH of a new transport block TB.

[0232] Specifically, after reporting the DPC, the terminal can determine the effective time of the new power level by scheduling the uplink transmission time corresponding to the PUSCH of a new transport block (TB) for the same HARQ process.

[0233] (6) For the same HARQ process, the effective time of the new power level is determined by scheduling the downlink transmission time corresponding to the physical downlink control channel (PDCCH) of a new transport block TB.

[0234] Specifically, after reporting the DPC, the terminal can determine the effective time of the new power level by scheduling the downlink transmission time corresponding to the PDCCH of a new transmission block TB for the same HARQ process.

[0235] In an embodiment of the present application, the terminal determines the effective time of the new power level through time offset, network activation or indication, network deactivation or indication, the time of the first uplink transmission after the uplink transmission carrying DPC, and for the same HARQ process, by scheduling the uplink transmission time corresponding to the PUSCH of a new TB or scheduling the downlink transmission time corresponding to the PDCCH of a new TB, thereby improving the flexibility of determining the effective time of the new power level.

[0236] Optionally, the terminal determines a UL fullpower mode after reporting the DPC or the new power level takes effect.

[0237] Specifically, after reporting the DPC or the new power level takes effect, the terminal needs to determine the UL full power mode.

[0238] Optionally, determining the UL full power mode includes at least one of the following:

[0239] (a) Determine the UL full power mode through reconfiguration of Radio Resource Control (RRC).

[0240] Specifically, after the terminal reports the DPC or the new power level takes effect, the network side device configures the UL full power mode to the terminal through RRC reconfiguration. After receiving the RRC reconfiguration of the network side device, the terminal can determine the UL full power mode through RRC reconfiguration.

[0241] (b) Determine, through RRC configuration, at least one UL full power mode corresponding to the power level.

[0242] Specifically, after the terminal reports the DPC or the new power level takes effect, the network side device can configure at least one UL full power mode corresponding to the power level to the terminal through RRC configuration. After receiving the RRC configuration of the network side device, the terminal can determine at least one UL full power mode corresponding to the power level through RRC configuration.

[0243] For example, for a terminal with power level 1.5, three UL full power modes can be configured. When the power level of the terminal falls back from power level 1.5 to power level 2, after the terminal receives the UL full power mode corresponding to the uplink full power transmission PC2-r18 (ul-FullPowerTransmissionPC2-r18) parameter configured by the network side device, the terminal needs to use the UL full power mode configured by the ul-FullPowerTransmissionPC2-r18 parameter.

[0244] (c) Determine the UL full power mode through DCI or MAC-CE configuration.

[0245] Specifically, after the terminal reports the DPC or the new power level takes effect, the network side device can configure the UL full power mode to the terminal through DCI or MAC-CE configuration. After receiving the DCI or MAC-CE configuration from the network device, the terminal can determine the UL full power mode through the DCI or MAC-CE configuration.

[0246] (d) Determine the UL full power mode through DCI or MAC-CE indication.

[0247] Specifically, after the terminal reports the DPC or the new power level takes effect, the network side device can indicate whether the UL full power mode of the terminal has changed through the indication of DCI or MAC-CE.
