In some embodiments, uplink coverage has always been one of the bottlenecks of system performance, which will affect signal quality and user experience. Uplink coverage enhancement is an urgent problem to be solved.

In some embodiments, the new radio (new radio, NR) supports uplink transmission waveforms, such as CP-OFDM and DFT-S-OFDM.

In some embodiments, the uplink transmission waveform is semi-statically configured through Radio Resource Control (RRC), and the parameters for configuring PUSCH are as shown in Figure 1b.

In some embodiments, the DFT-S-OFDM waveform has a lower PAPR and the CP-OFDM waveform has a higher PAPR.

For example, as shown in Figure 1c, in some cases, the PAPR under the DFT-S-OFDM waveform will be about 3 decibels (dB) lower than the PAPR of CP-OFDM.

Therefore, the DFT-S-OFDM waveform is more suitable for scenarios with limited uplink coverage, such as cell edge users. For another example, for frequency range (FR) 2, the uplink coverage of the DFT-S-OFDM waveform is more prominent.

In some embodiments, a specific transmission waveform of the uplink scheduled PUSCH channel is indicated by adding 1 bit to the downlink control information (DCI).

In some embodiments, the maximum transmission power that a terminal is allowed to reduce due to higher order modulation and transmission bandwidth configuration is defined. For example, for terminal power class (PC) 2, Table 2 defines the allowed maximum power reduction (MPR) for channel bandwidths that meet the following two standards; for PC3, Table 3 defines the allowable maximum power reduction (MPR) for channel bandwidths that meet the following two criteria. A standard channel bandwidth defines the allowed MPR.

Table 2

table 3

In some embodiments, additional transmission requirements may be communicated to the terminal via network signaling. Each additional emission requirement is associated with a unique network signal (NS) value, which is indicated in the RRC signaling by the NR band number of the applicable operating frequency band and the associated value in the field. For example, the NR frequency band number of the applicable operating frequency band and the associated value in the field may be additional spectrum emission.

Illustratively, to meet additional requirements, additional maximum power reduction (A-MPR) is allowed to the maximum output power specified in Table 2 and/or Table 3. Unless otherwise stated, the total reduction in the terminal's maximum transmission power is the maximum of MPR and A-MPR. Among them, MPR refers to the above description.

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

Optionally, the value of _PCMAX,f,c is between _{PCMAX_L,f,c} and _{PCMAX_H,f,c} . That is to say Among them, _PCMAX,f,c is the maximum transmission power, _{PCMAX_L,f,c} is the low value of the maximum transmission power, and _{PCMAX_H,f,c} is the high value of the maximum transmission power.

Optionally, P _{CMAX_L,f,c} is determined based on Equation 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

Among them, f represents the carrier frequency, c represents the serving cell, P _{EMAX, c} represents the maximum allowable power configured by the network equipment, P _PowerClass represents the terminal defined power without considering other non-ideal factors (tolerance), ΔP _PowerClass represents the maximum power reduction of the terminal Or based on duty cycle configuration, in order to ensure the power backoff value of radio frequency radiation exposure, MPR _c indicates the maximum power backoff amount due to modulation method and transmission bandwidth configuration factors, and A-MPR _c indicates that in order to ensure the relevant radiation requirements of different operating frequency bands, the network The additional power backoff signaled, ΔT _IB,c represents the additional power backoff value under multi-carrier, ΔT _C,c represents the additional power backoff value corresponding to the transmission of special edge configuration, ΔT _RxSRS represents the SRS antenna Switch the relevant terminal power adjustment value, P-MPR _c represents the maximum power attenuation of power management.

Optionally, P _{CMAX_H,f,c} is determined based on Equation 2:

P _{CMAX_H,f,c} =MIN{P _EMAX,c ,P _PowerClass -ΔP _PowerClass } Formula 2

In some embodiments, the terminal may report a power headroom report (PHR). The PHR may include power headroom (PH), maximum transmission power P _CMAX,f,c and power management maximum power reduction (power-maximum power reduction, P-MPR). Among them, the power headroom reflects the amount of additional transmit power that the terminal can send with reference to the current PUSCH power level, and _PCMAX,f,c reflects the maximum power that the terminal can deliver in this situation, and the current protocol stipulates that P- MPR reports only for the FR2 band. It can be understood that the PHR provides instant information reporting a set of parameters for specific PUSCH transmission of the network device.

For example, Figure 1d shows the currently specified single-carrier PHR configuration format. Among them, the P indication field is used to indicate whether there is an MPE; the reserved bit can be recorded as R. It can be understood that the reserved bit usually does not contain any information and is mainly used to record corresponding new data when needed. The power headroom 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 reserved bit. Among them, MPE related information is used to record P-MPR in the case of FR2.

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

In some embodiments, two uplink transmission waveforms are supported in PUSCH transmission, including CP-OFDM waveform and DFT-S-OFDM waveform. Compared with CP-OFDM, the DFT-S-OFDM waveform is more suitable for scenarios with limited uplink coverage, such as cell edge users, due to its lower PAPR characteristics. Therefore, the CP-OFDM waveform and the DFT-S-OFDM waveform can be dynamically switched.

When dynamically switching uplink transmission waveforms, there is a problem of inaccurate scheduling.

Therefore, the present disclosure reports the power information of different waveforms used by PUSCH when reporting terminal capability information, so that the network device can more accurately dynamically switch the waveform used by PUSCH.

In some embodiments, the terminal determines the waveform used to send the PUSCH based on the second information. That is, the terminal determines the waveform used to send PUSCH based on the waveform used to send message 3 during the random access process. For example, if the waveform used to send message 3 during the random access process is CP-OFDM, the terminal can confirm that the waveform used to send PUSCH is CP-OFDM.

In some embodiments, the network device semi-statically configures the waveform used by the terminal to send PUSCH through RRC signaling.

In some embodiments, RRC signaling includes parameters for indicating waveforms, such as transform precoder parameters. For example, if the conversion precoding parameters include enabled information, the terminal can be configured to use the DFT-S-OFDM waveform. For another example, if the conversion precoding parameters include disabled information, the terminal can be configured to use other waveforms, such as CP-OFDM waveforms.

In some embodiments, parameters indicating waveforms are not included in the RRC signaling. The terminal may determine the waveform used to send the PUSCH based on the second information, that is, determine the waveform used to send the PUSCH based on the waveform indicated by message 3 in the random access process.

Among them, the value of PH can be positive, negative or 0. Among them, the PUSCH transmit power is calculated by the above formula 1, which is not the actual transmit power of the terminal, so the value of PH can be a negative value.

In some embodiments, terms such as "uplink", "uplink" and "physical uplink" may be replaced by each other, and terms such as "downlink", "downlink" and "physical downlink" may be replaced by each other.

For example, the PHR includes the PHR corresponding to the target waveform. In some embodiments, the waveform may include CP-OFDM. In some embodiments, the waveform may include DFT-S-OFDM.

Since the power headroom information involves the difference between parameters of different waveforms, both the terminal 101 and the network device 102 can be considered as the difference between the parameters of the currently used waveform and the parameters of the target waveform. Among them, for the network device 102, if the waveform used by the terminal is configured by the network device 102, the network device can determine the waveform currently used by the terminal 101.

Of course, the above waveforms are only illustrative examples, and the waveforms used by PUSCH are not limited thereto, and the disclosure is not limited thereto.

For example, the target waveform may be a waveform after dynamic waveform switching.

In some embodiments, the target waveform can be determined based on different scenarios. For example, for scenarios with limited uplink coverage, such as cell edge users, compared with CP-OFDM, the DFT-S-OFDM waveform is more suitable because of its lower PAPR, then If the currently used waveform is a CP-OFDM waveform, the target waveform can be a DFT-S-OFDM waveform.

The first condition is related to, or related to, the power of the second waveform. The first waveform is, for example, the current waveform, and the second waveform is, for example, the target waveform.

In some embodiments, the terminal meets the first condition to trigger the measurement and/or transmission of the PHR. For example, the first condition may be that the power parameter value corresponding to the PUSHC transmission or PUSCH transmission opportunity satisfies the power parameter threshold value; or, the first condition may be, for example, the PHR prohibition timer expires or times out; or, the first condition may be, for example, PHR When the power factor change parameter (phr-tx-power factor change) is less than the path loss.

For example, the proportion threshold can be set to 50%. Assume that the power parameter value corresponding to 6 PUSCH transmissions among 10 PUSCH transmissions meets the power threshold value, that is, the proportion is 60%, then during multiple PUSCH transmissions If the proportion of the power parameter value that satisfies the power parameter threshold is greater than the proportion threshold, the measurement and/or transmission of the PHR can be triggered.

In some cases, when the proportion of power parameter values satisfying the power parameter threshold value in multiple PUSCH transmissions is greater than the proportion threshold value, the measurement and/or transmission of PHR is triggered. For example, the proportion threshold can be set to 50%. Assume that there are power parameter values corresponding to 5 PUSCH transmissions out of 10 PUSCH transmissions that meet the power threshold value, that is, the proportion is 50%. Then there are power parameter values among multiple PUSCH transmissions that meet the power threshold value. The proportion of the parameter threshold value is equal to the proportional threshold value, which can trigger the measurement and/or transmission of the PHR.

Of course, the above-exemplified scenarios and specific values of the proportion threshold are only for explanation, and the present disclosure does not limit them.

Optionally, if there are multiple PUSCH transmissions in which the power parameter value satisfies the power parameter threshold and the number of transmissions is greater than the number threshold, the measurement and/or transmission of the PHR is triggered. For example, the frequency threshold can be 5 times. Assume that the power parameter value corresponding to the 5th PUSCH transmission has met the power threshold value. At this time, if the power parameter value corresponding to the 6th PUSCH transmission has met the power threshold value, , then there are multiple PUSCH transmissions whose power parameter value satisfies the power parameter threshold and the number of transmissions is greater than the number threshold, which can trigger the measurement and/or transmission of PHR.

In some cases, the number of transmissions in which the power parameter value satisfies the power parameter threshold value in multiple PUSCH transmissions is equal to the number threshold value, triggering the measurement and/or transmission of PHR. For example, the frequency threshold can be 5 times. Assume that the power parameter value corresponding to the PUSCH transmission has occurred 4 times in the PUSCH transmission and meets the power threshold value. At this time, if the power parameter value corresponding to the 5th PUSCH transmission meets the power threshold value, , then the number of transmissions in which the power parameter value satisfies the power parameter threshold value in multiple PUSCH transmissions is equal to the number threshold value, which can trigger the measurement and/or transmission of PHR.

Optionally, the proportion of power parameter values satisfying the power parameter threshold value in multiple PUSCH transmission opportunities is greater than or equal to the proportion threshold value.

Optionally, among the multiple PUSCH transmission opportunities, the number of transmission opportunities whose power parameter value satisfies the power parameter threshold value is greater than or equal to the number threshold value.

You may refer to the above-mentioned power parameter value based on single or multiple PUSCH transmissions that satisfies the power parameter threshold value. The parameter threshold value and the specific method of triggering the measurement and/or sending of the PHR will not be described in detail here.

In some embodiments, expiration or timeout of the PHR prohibition timer may trigger measurement and/or reporting of PHR, where the PHR prohibition timer may be phr-prohibittimer. For example, within the period of the PHR prohibition timer, the measurement and/or transmission of PHR can be triggered based on the power parameter value of a single or multiple PUSCH transmissions meeting the power parameter threshold value; when the PHR prohibition timer expires, then Actively trigger PHR measurement and/or reporting. For another example, if within the period of the PHR prohibition timer, the power parameter value based on a single or multiple PUSCH transmissions meets the power parameter threshold value, the measurement and/or transmission of the PHR is not triggered. Then, when the PHR prohibition timer expires, the measurement and/or reporting of PHR is actively triggered, and the terminal re-determines based on whether the power parameter value of single or multiple PUSCH transmissions after this PHR report meets the power parameter threshold value. Whether to trigger measurement and/or sending of PHR.

In some embodiments, when the PHR power factor change parameter is less than the path loss, the measurement and/or reporting of the PHR may be triggered. For example, when phr-tx-power factor change is not less than the path loss, the measurement and/or transmission of PHR can be triggered based on the power parameter value of single or multiple PUSCH transmissions meeting the power parameter threshold; when phr-tx-powerfactor When the change is less than the path loss, PHR measurement and/or reporting is actively triggered. For another example, when the phr-tx-powerfactor change is not less than the path loss, the power parameter value based on single or multiple PUSCH transmissions meets the power parameter threshold, and the measurement and/or transmission of PHR is not triggered. Then, when the phr-tx-power factor change is less than the path loss, the measurement and/or reporting of PHR is actively triggered, and the terminal re-based on the power parameter value of single or multiple PUSCH transmissions after this PHR report satisfies the power parameter gate. Limit value to determine whether to trigger PHR measurement and/or transmission.

In some embodiments, when the PHR power factor change parameter is not less than the path loss, the measurement and/or reporting of the PHR may be triggered. For example, when the phr-tx-power factor change is not less than the path loss, when the power parameter value of multiple PUSCH transmissions meets the power parameter threshold value, the measurement and/or transmission of PHR is triggered.

In some embodiments, the relationship between the PHR power factor change parameter and the path loss affects the proportional threshold or the frequency threshold. For example, when the PHR power factor change parameter (phr-tx-power factor change) is less than the path loss, the number threshold can be 5 times. Assume that the power parameter value corresponding to 5 PUSCH transmissions has occurred in PUSCH transmission and meets the power threshold value. This , if the power parameter value corresponding to the sixth PUSCH transmission meets the power threshold value, then there are multiple PUSCH transmissions with a power parameter value that meets the power parameter threshold value and the number of transmissions is greater than the number threshold value, the measurement and/or PHR can be triggered. or send.

In some embodiments, the multiple PUSCH transmissions include multiple scheduling-based PUSCH transmissions, or include multiple scheduling-based and scheduling-free-based PUSCH transmissions, or include multiple scheduling-based and scheduling-free-based PUSCH transmissions of the same waveform configuration. . For example, when the multiple PUSCH transmissions include multiple PUSCH transmissions based on scheduling, the measurement and sending of the PHR of the multiple PUSCH transmissions based on scheduling may be triggered to facilitate the network device to switch the waveform used for the PUSCH transmission based on scheduling. of scheduling. For another example, when multiple PUSCH transmissions include multiple scheduling-based and scheduling-free PUSCH transmissions, the measurement and transmission of the scheduling-based and scheduling-free PHRs may be triggered, so that the network device can monitor the scheduling-based PUSCH transmissions. Scheduling of waveform switching. That is, the PHR of the scheduling-free PUSCH transmission can be used as a reference to schedule the waveform switching used in the scheduling-based PUSCH transmission. For another example, when multiple PUSCH transmissions include multiple scheduling-based and scheduling-free PUSCH transmissions with the same waveform configuration, the measurement and transmission of the scheduling-based and scheduling-free PHR can be triggered, and the PHR used for scheduling-based PUSCH transmission can be triggered. Waveform switching is scheduled. The same waveform may be a target waveform, for example. When the power parameters of the scheduling-based and scheduling-free PUSCH transmission configured in the target waveform meet the power parameter threshold, the trigger may trigger the measurement and sum of the scheduling-based and scheduling-free PHR. send. That is, it can be considered that the target waveform meets the conditions for use, and the currently used waveform can be dynamically switched to the target waveform.

In some embodiments, a single PUSCH transmission or multiple PUSCH transmissions may be PUSCH transmissions based on timeline requirements.

In some embodiments, a single PUSCH transmission opportunity or multiple PUSCH transmission opportunities may be PUSCH transmission opportunities based on timeline requirements.

In some embodiments, a single PUSCH transmission or multiple PUSCH transmissions include: a single or multiple PUSCH transmissions after the latest PHR is sent. For example, the measurement and/or transmission of PHR may be triggered based on the power parameters of single or multiple PUSCHs after the latest PHR transmission meeting the power parameter threshold.

In some embodiments, the single PUSCH transmission opportunity or multiple PUSCH transmission opportunities include single or multiple PUSCH transmission opportunities after the latest PHR was sent. For example, the measurement and/or transmission of the PHR may be triggered based on the power parameters of a single PUSCH transmission opportunity or multiple PUSCH transmission opportunities after the latest PHR is sent that meet the power parameter threshold.

In some embodiments, meeting the power parameter threshold includes a pH value greater than the first pH value threshold.
