[0116] For example, as shown in FIG. 1C , in some cases, the PAPR of the DFT-S-OFDM waveform is approximately 3 decibels (dB) lower than the PAPR of the CP-OFDM waveform.

[0117] Therefore, the DFT-S-OFDM waveform is more suitable for scenarios with limited uplink coverage, such as cell-edge users. For example, in frequency range (FR) 2, the DFT-S-OFDM waveform has better uplink coverage.

[0118] In some embodiments, one bit is added to downlink control information (DCI) to indicate a specific uplink scheduling PUSCH channel transmission waveform.

[0119] In some embodiments, due to high-order modulation and transmission bandwidth configurations, a maximum transmit power reduction allowed for a terminal is defined. For example, for terminal power class (PC) 2, Table 1 defines the maximum power reduction (MPR) allowed for channel bandwidths that meet the following two criteria; for PC 3, Table 2 defines the maximum power reduction (MPR) allowed for channel bandwidths that meet the following two criteria.

[0120] Table 1

[0121] 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 in RRC signaling by the NR band number of the applicable operating frequency band and the associated value in the field. For example, the NR band number of the applicable operating frequency band and the associated value in the field may be additional spectrum emission.

[0122] Exemplarily, to meet additional requirements, an additional maximum power reduction (A-MPR) is permitted for the maximum output power specified in Table 1 and / or Table 2. Unless otherwise specified, the total reduction in the terminal's maximum transmit power is the maximum of the MPR and the A-MPR. MPR refers to the above description.

[0123] 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 PCMAX,f,c is set for the carrier f of the serving cell c.

[0124] Optionally, P CMAX,f,c The value of P CMAX_L,f,c and P CMAX_H,f,c Between. That is, P CMAX_L,f,c ≤P CMAX,f,c ≤P CMAX_H,f,c 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.

[0125] Table 2

[0126] 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

[0127] Where f represents the carrier frequency, c represents the serving cell, 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 cIndicates 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.

[0128] 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

[0129] In some embodiments, the terminal may report a power headroom report (PHR). The PHR may include power headroom (PH), maximum transmit power PCMAX,f,c, and power management maximum power reduction (P-MPR). The power headroom reflects the amount of additional transmit power that the terminal can transmit based on the current PUSCH power level, while PCMAX,f,c reflects the maximum power that the terminal can transmit in this case. The current protocol stipulates that P-MPR is only reported for the FR2 frequency band. It can be understood that the PHR provides instantaneous information for reporting a set of parameters for specific PUSCH transmissions of the network device.

[0130] For example, Figure 1D 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.

[0131] For another example, Figure 1E 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.

[0132] In some embodiments, two uplink waveforms are supported for PUSCH transmission: CP-OFDM and DFT-S-OFDM. Compared to CP-OFDM, DFT-S-OFDM is more suitable for uplink coverage-limited scenarios, such as cell-edge users, due to its lower PAPR. Therefore, dynamic switching between the CP-OFDM and DFT-S-OFDM waveforms is possible.

[0133] However, during the PHR reporting process, various reasons may cause frequent switching between the CP-OFDM waveform and the DFT-S-OFDM waveform.

[0134] Therefore, the present disclosure reports the PHR based on the first time interval to avoid the problem of too frequent waveform switching between CP-OFDM and DFT-S-OFDM caused by the PHR reporting process.

[0135] FIG2 is an interactive diagram of the xx method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to the xx method, which includes:

[0136] Step S2101: Terminal 101 determines a first time interval.

[0137] In some embodiments, the first time interval may be predefined or based on a network device (network device 102 or other network device other than network device 102) configuration.

[0138] 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.

[0139] In some embodiments, the first time interval includes at least one of the following:

[0140] The interval for periodically sending PHR;

[0141] The time interval for sending PHR aperiodically;

[0142] The interval of the prohibit timer used to trigger the aperiodic transmission of PHR.

[0143] 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", "time", and "time interval" can be replaced with each other.

[0144] In some embodiments, the time interval of the prohibition timer for triggering the aperiodic transmission of the PHR may be determined based on a triggering event.

[0145] For example, assuming that triggering event A activates the prohibit timer for sending a PHR, and that when event A ends, the prohibit timer for sending a PHR is deactivated, the duration of event A can be considered the duration of the prohibit timer for sending a PHR being activated. In other words, the duration of event A can be considered the first time interval.

[0146] In some embodiments, the first time interval may be represented based on at least one of the following:

[0147] Symbols, time slots, and subframes.

[0148] In some embodiments, terms such as "frame", "radio frame", "subframe", "slot", "sub-slot", "mini-slot", "symbol", "symbol", and "transmission time interval (TTI)" can be used interchangeably.

[0149] Step S2102: Terminal 101 sends first information.

[0155] In some embodiments, terms such as "send", "transmit", "report", "download", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0156] In some embodiments, the PHR may be used to indicate power information of different waveforms used by the terminal 101 to send the PUSCH.

[0157] Optionally, the PHR may be used to indicate power information of different waveforms used by the terminal 101 to send the PUSCH at full power.

[0158] 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", and "chip" can be used interchangeably.

[0159] 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.

[0160] Step S2103: the network device 102 sends the second information.

[0161] In some embodiments, the network device 102 sends second information to the terminal 101 .

[0162] In some embodiments, terminal 101 receives second information.

[0163] In some embodiments, the second information is used to indicate a dynamically switched waveform.

[0164] Optionally, the network device 102 sends downlink control information (DCI) to the terminal 101 for indicating the dynamic switching waveform.

[0165] In some embodiments, the actions of the network device 102 sending the second information and the terminal 101 sending the first information are independent of each other.

[0166] In some embodiments, the content indicated by the second information includes at least one of the following: indicating a waveform change, or not indicating a waveform change.

[0167] In some embodiments, the terms "no indication of waveform change", "indicating that the waveform does not change", "not expected to indicate a waveform change", "indicating that the waveform is not expected to change", etc. can be used interchangeably.

[0168] In some embodiments, the second time interval is determined based on a sending time of the first information and a sending time of the second information.

[0169] Optionally, the second time interval is a time interval between the terminal 101 sending the first information and the network device 102 recently receiving the second information.

[0170] Exemplarily, the terminal 101 transmits a PHR based on the PUSCH, and the network device 102 sends a DCI for instructing dynamic waveform switching, and the time interval between the most adjacent time points of transmitting the PHR and sending the DCI is determined as the second time interval.

[0171] Step S2104: Terminal 101 sends a PHR based on the first time interval.

[0172] In some embodiments, the terminal 101 sends a PHR to the network device 102 based on a first time interval.

[0173] In some embodiments, the network device 102 receives the PHR sent by the terminal 101 based on a first time interval.

[0174] In some embodiments, terminal 101 sends the PHR based on a size relationship between the first time interval and the second time interval.

[0175] In some embodiments, the first time interval is greater than the second time interval, and the terminal 101 has the following two optional ways of sending the PHR:

[0176] -A) In response to the second time interval being greater than the first time interval, the terminal 101 sends PHRs corresponding to different waveforms.

[0177] Exemplarily, in response to the second time interval being greater than the first time interval, the PHR corresponding to the CP-OFDM waveform and the PHR corresponding to the DFT-S-OFDM waveform are sent.

[0178] -B) In response to the second time interval being greater than the first time interval, the terminal 101 sends a PHR corresponding to one or two waveforms.

[0181] Send the PHR corresponding to the CP-OFDM waveform and the PHR corresponding to the DFT-S-OFDM waveform.

[0182] It should be understood that the second time interval is greater than the first time interval, which can be understood as that the terminal 101 does not receive new second information during the period when the terminal 101 sends the PHR.

[0183] In some embodiments, the target waveform is reported based on the following two situations: in response to the second time interval being less than or equal to the first time interval, or in response to the second time interval being greater than the first time interval.

[0184] In some embodiments, in response to the second time interval being less than or equal to the first time interval, terminal 101 sends a PHR corresponding to the target waveform.

[0185] It should be understood that the second time interval is less than or equal to the first time interval, which can be understood as that the terminal 101 receives new second information during the period when the terminal 101 sends the PHR. In other words, the terminal 101 receives the second information indicating the dynamic switching waveform during the period when the terminal 101 sends the PHR.

[0186] Optionally, in response to the most recently received second information indicating a waveform change, the waveform currently used for transmission indicated by the second information is determined as the target waveform, and the target waveform is reported.

[0188] Optionally, in response to the most recently received second information not indicating a waveform change, the waveform to be switched determined based on the PHR is determined as the target waveform, and the target waveform is reported.

[0189] Exemplarily, if the terminal 101 and the network device 102 communicate using a DFT-S-OFDM waveform before receiving the second information, in response to receiving the second information and the second information does not indicate a waveform change, the DFT-S-OFDM waveform is determined as the target waveform and reported.

[0191] Exemplarily, if the terminal 101 and the network device 102 currently communicate using a DFT-S-OFDM waveform, in response to not receiving the second information, the DFT-S-OFDM waveform is determined as the target waveform and reported.

[0192] In some embodiments, in response to the second time interval being greater than the first time interval, terminal 101 sends a PHR corresponding to the target waveform.

[0196] Exemplarily, if the terminal 101 and the network device 102 communicate using a DFT-S-OFDM waveform before receiving the second information, in response to receiving the second information and the second information does not indicate a waveform change, the DFT-S-OFDM waveform is determined as the target waveform and reported.

[0197] In some embodiments, in response to not receiving the second information, the waveform currently used for transmission is determined as the target waveform, and the target waveform is reported.

[0198] Exemplarily, if the terminal 101 and the network device 102 currently communicate using a DFT-S-OFDM waveform, in response to not receiving the second information, the DFT-S-OFDM waveform is determined as the target waveform and reported.

[0199] In some embodiments, the PHR corresponding to each of the different waveforms is determined based on at least one of the following methods:

[0200] Determined based on a scheduling grant PUSCH, or based on a configuration grant (Configuration Grant) PUSCH.

[0201] In some embodiments, the terms "scheduled granted PUSCH" and "scheduled granted PUSCH" can be used interchangeably.

[0202] In some embodiments, determining the PHR based on a scheduling grant (PUSCH) includes: in response to the presence of a first scheduling grant PUSCH, determining the PHRs corresponding to different waveforms based on the first scheduling grant PUSCH.

[0203] In some embodiments, the first scheduling grant PUSCH is a PUSCH scheduled for transmission in the second time interval.

[0204] In response to the absence of the first scheduling grant PUSCH, PHRs corresponding to different waveforms are determined based on the second scheduling grant PUSCH or the third PUSCH.

[0205] In some embodiments, the second scheduling grant PUSCH is the PUSCH most recently scheduled for transmission before the second time interval.

[0206] In some embodiments, the third PUSCH is a predefined or configured reference PUSCH.

[0207] In some embodiments, determining the PHR based on the configuration grant PUSCH includes: in response to the presence of the configuration grant PUSCH, determining the PHRs corresponding to the different waveforms based on the configuration grant PUSCH.

[0208] In some embodiments, the terms "configured authorized PUSCH" and "configured authorized PUSCH" can be used interchangeably.

[0209] In some embodiments, in response to the presence of a configuration grant PUSCH, and the waveform indicated by the most recently received second information is the same as the waveform transmitted by the configuration grant PUSCH, PHRs corresponding to different waveforms are determined based on the configuration grant PUSCH.

[0210] Exemplarily, in response to the existence of a configured authorized PUSCH, the waveform of the configured authorized PUSCH transmission is a DFT-S-OFDM waveform, and the waveform indicated by the second information is also a DFT-S-OFDM waveform, then the PHR corresponding to the DFT-S-OFDM waveform is determined.

[0211] Alternatively, in response to the existence of a configured granted PUSCH, the waveform transmitted by the configured granted PUSCH is a CP-OFDM waveform, and the waveform indicated by the second information is also a CP-OFDM waveform, then the PHR corresponding to the CP-OFDM waveform is determined.

[0212] In some embodiments, the terminal 101 may send the PHR on a periodic basis, or may send the PHR on an aperiodic basis.
