- the NR UE transmits the NR channel or signal only on the NR TDD band.
- the NR UE transmits the NR channel or signal only on the LTE FDD UL shared carrier.
- the NR UE transmits the NR channel or signal simultaneously on the NR TDD band and on the LTE FDD UL shared carrier, how to allocate power.
- the NR UE also has the capability of supporting LTE transmission, and it also transmits an LTE channel or signal on the LTE FDD UL carrier. At this time, how the UE allocates the power of the NR UL and the LTE UL is a problem to be solved in this embodiment.

- the embodiment includes a plurality of different examples:
- the NR can transmit with the LTE shared LTE frequency band, that is, the NR can transmit the NR service on the LTE frequency band.
- the UL carrier frequency of the LTE is F1 (for example, located near 700 MHz)
- the downlink (DL) carrier frequency is F2 (the FDD carrier paired with F1 is also located.
- the dedicated carrier frequency of NR is F3 (for example, 3.5 GHz, TDD carrier).

- Wireless channels including path loss, penetration loss, and shadow fading, are quite different;
- TX Transmit
- RX Radio
- NR UEs their downlink path loss measurements are based on signals transmitted on the NR dedicated carrier frequency F3, which depends on the estimated downlink path loss.
- This algorithm is based on the same uplink and downlink frequencies or The assumption is that there is little difference (for example, the same is 700MHz) and the path loss is not much different.
- the residual difference can be corrected by closed loop power control. Therefore, there is no problem with the UL open loop power control on the NR dedicated carrier frequency F3.
- the measurement result on the F3 cannot be directly applied to the uplink shared carrier F1, and the NR UE cannot know the path loss on the shared F1, and thus the accurate UL power control cannot be performed. Therefore, it is necessary to solve the path loss estimation and uplink power control problem on the shared carrier.
- FIG. 3 is a schematic diagram of an NR uplink and downlink transmission carrier frequency according to an embodiment of the present application.

- the uplink carrier with the paired carrier on the downlink means that the uplink carrier and the downlink carrier have a small frequency interval and the frequency characteristics are not significantly different, and both the uplink carrier and the downlink carrier can be used for NR transmission.
- the path loss or UL power control of the uplink carrier can be obtained based on the downlink carrier.
- the uplink and downlink carriers are all located at 700MHz or 1700MHz.
- both the UL carrier and the DL carrier of the LTE 700 MHz are shared with the NR. Then, when the NR transmits a preamble on a 700 MHz UL carrier, the obtained path loss can be calculated based on the DL carrier.
- LTE 700MHz only has UL carrier and NR sharing (LTE 700MHz DL carrier is not heavily shared with NR due to heavy load).
- the preamble can only be sent on the NR dedicated carrier (3.5 GHz).
- the UL power transmitted by the preamble is based on the estimated downlink path loss on the NR dedicated carrier.

- the path loss in the high frequency band is 110 dB
- the path loss in the low frequency band is 100 dB.
- Their path loss offset (PL_offset) is 10 dB.
- the preamble Initial Received Target Power of the low frequency band is equal to the preamble Initial Received Target Power of the high frequency band minus 10 dB.
- DELTA_PREAMBLE is similar.
- the downlink loss, the preamble Initial Received Target Power, and the preamble power deviation (DELTA_PREAMBLE) calculated by the UE in the high frequency band can determine the uplink power of the first transmission preamble, and the subsequent transmission failure can be performed. Power ramping up.
- Method 3 Estimating the path loss offset (PL_offset) between the high and low frequency bands according to the frequency difference between the high and low frequency bands and the antenna configuration.

- the UE determines the path loss offset (PL_offset) between the high and low frequency bands according to the low frequency band frequency information (shared carrier frequency information) or the combination of the low frequency band and the high frequency band (shared carrier and dedicated carrier frequency band).
- the downlink loss and the path loss offset (PL_offset) calculated by the UE according to the high frequency band are used to obtain the downlink path loss of the low frequency band, thereby calculating the uplink power transmitted by the transmitting preamble on the low frequency band.
- the dedicated carrier frequency of the NR is 3.3-4.2 GHz (DL and UL), and there are four cases in which the LTE shared UL carrier frequency that can be used.
- the path loss offset (PL_offset) is estimated in advance based on parameters such as the dedicated carrier and the shared carrier frequency difference.
- the shared carrier and the dedicated carrier frequency band combination number are notified to the UE through system information (system information block 2, SIB2), and the UE can know the path loss offset (PL_offset) between the high and low frequency bands according to the serial number, thereby obtaining an accurate low frequency band. Road damage.

- the low frequency band for example, the LTE shared carrier frequency F1.
- Method 1 The same as Method 3 of the initial access.

- the compensation coefficient ⁇ of the high frequency band is set to 1
- the compensation coefficient ⁇ of the low frequency band is set to 0.9, and the compensation can reach 11 dB.
- PL is the calculated high frequency downlink loss. This value is close to the actual 700MHz path loss, and the residual difference can be corrected by closed loop power control.
- ⁇ can take more values, the accuracy of the compensation is more accurate.
- ⁇ can be equal to 0.95, 0.85, 0.75, and 0.65, and the like.
- the nominal power P0 is further divided into two parts: the cell nominal power and the UE-specific nominal power.
- the evolved base station (eNodeB) semi-statically sets the physical uplink shared channel nominal power (P0_PUSCH) and the physical uplink control channel nominal power (P0_PUCCH) for all UEs in the cell, and the value is broadcast by the SIB2 system message; wherein, P0_PUSCH
- P0_PUSCH The range of values is -126 dBm (dBm) to +24 dBm (both for Resource Blocks (RBs)).
- the value range of P0_PUCCH is -126dBm to -96dBm.
- each UE may also have a UE-specific nominal power offset, which is delivered to the UE through dedicated RRC signaling.
- P0_UE_PUSCH and P0_UE_PUCCH are respectively an offset of different system for system nominal power P0_PUSCH and P0_PUCCH, and the unit is dB, which takes a value between -8 and +7.
- the range of P0 is actually large enough to cover the path loss difference existing at 3.5 GHz and 700/800/900/1.7 GHz.
- the initial phase can be adjusted by at least one of the following: P0 and ⁇ , which can be subsequently adjusted by the closed loop f.
- the value of the nominal power P0 may be expanded or may be taken. For example, to increase the UE specific nominal power offset, take a value between -16 and +15.
- the nominal power P0 includes path loss offset adjustment power associated with the high and low frequency frequencies in addition to the cell nominal power and the UE-specific nominal power. That is, the nominal power P0 is the sum of these three parts.

- the base station configures the UE to have ⁇ in the high frequency band of 1, and configures the UE to configure the low frequency band to be 0.9.
- the base station corrects the path loss offset of the low frequency band relative to the high frequency band through the closed loop f. For example, the base station configures the UE to configure f (absolute value or accumulated value) on the high frequency band to be 10 dB, and configure the UE to configure f (absolute value or integrated value) on the low frequency band to be 0 dB.
- Method 3 For the case where the uplink low carrier is used for NR UL transmission, the same frequency DL carrier or the downlink carrier paired with it is not used for the NR downlink service transmission, and the same frequency DL carrier or the downlink carrier matched with it can be used for NR.

- Solution 1 Two Pcmax, the sum of c needs to be equal to Pcmax, such as 23dBm.
- the two maximum powers are allocated semi-statically, such as: half-divided; according to the priority, the maximum transmit power with higher priority is larger, such as 40% and 60%. For example, if the MCG has a high priority, the Pcmax and c of the MCG are 60%.

- the power allocation priority is satisfied to be transmitted on a carrier with a high priority or a poor channel condition. If there is any remaining, it is used to send on other carriers.
- the shared carrier has a higher priority, 23 dBm first satisfies the shared carrier, and if there is remaining, it is reused for the dedicated carrier.
- the shared carrier channel condition is good.
- the UE is in a region with a low frequency coverage of the dedicated carrier. If the power is used for a dedicated carrier, the power is required to be large, and the performance is still poor, so it is not as good for the shared carrier.
- the shared carrier channel conditions are better, and the dedicated carrier channel conditions are relatively poor.
- the dedicated carrier channel conditions are relatively poor. For example, in the range of 3.5 GHz coverage, more power is allocated to the dedicated carrier, which ensures that UL performance can be guaranteed on both carriers.
- LTE and NR are DC scenarios, LTE is MeNB/MgNB/MCG, and NR is SeNB/SgNB/SCG. Or the configuration of the primary and secondary base stations is reversed.

- Method 2 The base station configures the minimum guaranteed transmission power for the eMBB and the URLLC, and the sum of the minimum guaranteed transmission power does not exceed the maximum transmission power of the UE.
- the remaining power is preferentially used for the URLLC, or the remaining power is preferentially used for a high priority transmission signal type (such as a control channel, etc.), or preferentially for transmitting an earlier service type.
- Method 3 The UE preferentially uses power for sending the URLLC. If there is remaining power, it is used to send eMBB. If there is no remaining power, eMBB will not be sent.
- Method 4 The UE reports the power condition or power headroom (PH) for the URLLC transmission to the base station.
- PH power headroom
- LTE and NR are DC scenarios, LTE is MeNB/MgNB/MCG, and NR is SeNB/SgNB/SCG. Or the configuration of the primary base station and the secondary base station are reversed.
- the UE calculates the power headroom PH.
- the PH may be the PH of the LTE carrier or the NR carrier, or the PH relative to the maximum transmit power of the UE.
- the reported PH can be reported to the MCG and/or SCG through the PUCCH or MAC CE.
- the LTE DC has two uplink power allocation modes: power control mode 1, PCM1 is generally used for synchronous DC, and UE is allocated for each CG. The minimum guaranteed power, the remaining power is shared by the MCG and SCG, depending on the type of information sent.
- Power control mode 2 (PCM2) is generally used for asynchronous DC, and the UE also allocates a minimum guaranteed power for each CG, and the remaining power is used by the CG whose transmission timing is early.
- NR is only used for eMBB UEs that use the same parameter numerology (eg, subcarrier spacing, cyclic prefix, etc.).
- PCM1 or PCM2 of LTE can be reused.
- NR has more scenarios and problems, so it is necessary to optimize the power control mechanism of NR carrier aggregation (CA)/dual connectivity (DC).
- CA NR carrier aggregation
- DC dual connectivity
- URLLC data For the UE, if UL eMBB data is being transmitted, UL URLLC data arrives at this time. URLLC data needs to be sent immediately to meet the latency requirements of the URLLC.
- URLLC should have a higher priority and should be allocated enough power. That is, the power requirements of the URLLC should be met. Assume that the power of the eMBB is P_embb and the power of the URLLC is P_urllc.
- P_urllc>Pcmax-P_embb that is, the power requirement of the URLLC is greater than the remaining power of the UE. Then, on the Orthogonal Frequency Division Multiplexing (OFDM) symbol that is simultaneously transmitted by eMBB and URLLC, P_embb should be lowered. The reduced power is used for the transmission of the URLLC. By performing this operation, the transmission power in one subframe or time slot is not kept constant. In order to achieve the above power allocation, two situations need to be considered:
- the gNB may send an explicit priority indication to the UE to re-allocate the power of the eMBB before the URLLC is sent.
- the symbol that needs to be re-allocated eMBB power may be the URLLC to be transmitted. That is, two-step power control can be used.
- Explicit priority indications can be sent via DCI.
- the gNB detects the UL URLLC signal sent by the UE.
- the gNB will assume that the UE reassigns the power of the eMBB based on a predefined principle.
- the pre-defined principle is the above-mentioned priority guarantee URLLC power principle.
- Different carriers on the NR's CA/DC can operate in different duplex modes.
- the minimum guaranteed power is still reserved for the uplink transmission according to the above. If a slot or subframe of a CG is changed from UL to DL/idle/reserved, the guaranteed power allocated to the CG can be given or reassigned to There is a CG transmitted by the UL service on this time slot.
- the guaranteed power of each CG (generally the minimum guaranteed power) can be fixed, or it can be lent to the other party when not in use. At this time, the minimum guaranteed power of the user is actually 0, and the minimum guaranteed power of the other party is the sum of the minimum guaranteed power of the previous party plus the minimum guaranteed power borrowed.
- the gNB may notify the UE of the link direction information of the slot/subframe or the information of the link direction change to the UE.
- the way to notify can be notified by DCI.
- DC is primarily used for mobility and coverage enhancement. If the guaranteed power (or minimum guaranteed power) is configured for each CG, the power of each CG or each gNB will be equal to or less than the maximum transmit power Pcmax, and power limitation will cause an uplink coverage problem. In order to solve the power limitation problem, it is necessary to consider how to use the reserved guaranteed power.
- the scheduling between different CGs and the HARQ (Hybrid automatic repeat request) mechanism are independent of each other because the connection between MgNB and SgNB is a non-ideal backhaul (backward back) connection. There is no dynamic interaction scheduling information between them.
- the UE has mastered all the information from the MgNB and the SgNB, and the two pieces of information can be shared in the internal implementation of the UE. Therefore, from the perspective of the UE, the DC can use more dynamic power allocation or power sharing.
- Method 1 Report more dynamic PHR (Power headroom) status or other information through UCI (Uplink Control Information).
- UCI Uplink Control Information
- Method 2 Reserve some slots/subframes for one of the gNB or CG semi-static, these slots/subframes can be used for UL transmission of the gNB or CG, and other gNBs or CGs in these slots/subframes Need to stop UL transmission.
- two types of slots/subframes are defined, a first type of slot/subframe for LTE and a second type of slot/subframe for NR.
- the NR cannot use the first type of time slot/subframe, but the NR can be used when LTE does not use it.
- LTE cannot use the second type of slot/subframe, but LTE can be used when NR does not use it.
- the above method can be used in conjunction with other power control schemes such as LTE DC PCM1/PCM2 (power scaling or minimum guaranteed power).
- LTE DC PCM1/PCM2 power scaling or minimum guaranteed power
- the UCI information in Method 1 and Method 2 includes at least one of the following:
- the i-th component carrier CCi in the CG is switched from UL to DL or idle in the slot/subframe/symbol.

- a part of the bandwidth can only be assumed to be a synchronization scenario, that is, a plurality of partial bandwidths between a wider bandwidth belong to the same Timing alignment group (TAG).
- TAG Timing alignment group
- a portion of the bandwidth between a wider bandwidth uses a common path loss value or reference signal received power (RSRP).
- the path loss value or RSRP is used for partial bandwidth for UL power control.

- CSI-RS channel state information-reference signal
- SS synchronization signal
- RRM radio resource management
- the CSI-RS or SS is separately transmitted over all or a part of the bandwidth on a wider bandwidth for RRM measurement. That is, RRM measurement is performed independently on all or part of the bandwidth, and uplink power control is performed using the RSRP or path loss value measured by itself.
- resource blocks (RBs) of some bandwidth edges are allocated lower power.
- Example 11 Frequency band combination of low frequency (LF) and high frequency (HF).
- LF low frequency
- HF high frequency
- the two carriers use the TDM method when performing CA/DC operations.
- the two carriers use the TDM method when performing CA/DC operations.
- other examples such as enhanced coverage.
- Example 12 supplementary uplink frequency (SUL)
- the main problem is that the characteristics of the SUL frequency and the dedicated carrier frequency are quite different.
- One method is to configure a downlink slot/subframe that is located on the downlink carrier of the SUL carrier or SUL pair.
- the CSI-RS/SS is transmitted on such downlink time slots/subframes for the UE to perform RSRP or path loss measurement.
- the measurement signal can be a periodic or aperiodic transmission. In order to reduce overhead, the period can be configured as a long period, or a long time to trigger a transmission and measurement.
- Two-step power control can be used to dynamically redistribute power, including:
- Step 1 Power allocation according to the existing UL power control algorithm. For example, an initial power control command is sent to the UE along with the scheduling grant.
- Step 2 Redistribute power if needed.
- the eMBB transmission power can be dynamically reduced even to 0 for the URLLC transmission of the UE or the interference to the neighboring URLLC service.
- the DCI in the second step includes at least one of the following information:
- the i-th component carrier CCi in the CG is switched from UL to DL or idle in the slot/subframe/symbol.
- the gNB detects the UL URLLC signal sent by the UE.
- the gNB will assume that the UE reassigns the power of the eMBB based on predefined rules.

- the second type of coded modulation scheme variable (Delta_MCS2): power redistribution. For example, when the eMBB part of the resource is used for the URLLC, power redistribution is performed, and the resource not used by the URLLC increases the value of the Delta_MCS2.
