For example, when UB and DA share a power amplifier, the power sharing problem between the two signals needs to be considered.

[0055] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the following is a further detailed description of the embodiments of the present invention through specific implementation methods in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0056] Figure 1 The UB link and DA link frequency division multiplexing in Figure 2 shown, or Figure 1 The UB link and DA link in the space division multiplexing are as follows Figure 3 When shown, Figure 3 In this embodiment, when UB and DA are spatially multiplexed, the frequency domain resources occupied by UB and DA at the same time partially overlap. In particular, when multiple beams of frequency domain multiplexing or spatial division multiplexing share one power amplifier, the power sharing problem between the two links needs to be considered. For example, Figure 2 or Figure 3 In the case of UB, the transmission power of DA link needs to be affected by the transmission power of UB link. Figure 1 When the total power of the signal sent from the IAB is limited, for example, the total power of the UB and DA sent from the IAB node 2 cannot exceed the predetermined threshold, the impact between the UB transmit power and the DA transmit power also needs to be considered.

[0057] On the other hand, even if the two signals of space division multiplexing or frequency division multiplexing do not share power, the total power is not limited. For example, UB and DA correspond to two independent power amplifiers of IAB node2 respectively. However, if the transmission power of the two space division multiplexing links is not equal, interference problems may occur, such as Figure 3 and Figure 1 As shown in Figure 1, when UB and DA are spatially multiplexed, if the UB's transmit power is significantly lower than the DA's, significant interference from the DA signal to the UB signal will occur at the IAB donor node / IAB node 1. Similarly, if the UB's transmit power is higher than the DA's, significant interference from the UB signal to the DA signal will occur at IAB node 3 / UE. When UB and DA are frequency-division multiplexed, although they occupy different physical resource blocks, if the power difference between the two signals is significant, power leakage from the higher-power signal can also cause significant interference to the other link.

[0058] The uplink power information is generally the power control information sent by the base station to the terminal, or the base station and the terminal agree on a specific power information range calculation formula. The terminal is reasonable in this range. When the reporting conditions are met, the terminal reports the final selected power information value to the base station. Figure 1The IAB donor node / IAB node1 sends power control information to IAB node2. Referring to protocol 38.213 and protocol 38.331, it can be seen that the power control information of the uplink channel allocated by the base station to the terminal includes the target received power P in the bandwidth part b (bandwidth part) of the carrier f in the serving cell c, and the target received power P in the jth set of power parameters. O_PUSCH,b,f,c (j), path loss adjustment factor α b,f,c (j) Downlink reference signal information q used for path loss calculation d , power adjustment parameter δ PUSCH,b,f,c , power process l. The above requires multiple sets of power control information, mainly because the uplink transmit power control parameters should be different due to different beam combinations used in the uplink channel. Specifically, the PUSCH transmit power is obtained according to formula (1).

[0059]

[0060] in, for K S =1.25, andΔ TF,b,f,c (i) = 0 for K S =0.

[0061] For the uplink data channel PUSCH, Where C is the number of code blocks, K r The number of bits included in each code block. For PUSCH with only uplink CSI (Channel state information), BPRE=0 CSI / N RE .in is the number of time domain symbols included in the i-th PUSCH transmission, It is the number of REs remaining in a PRB in the jth time domain symbol in the i-th PUSCH transmission after removing the demodulation reference signal. The specific meaning of other parameters can be referred to protocol 38.213.

[0062] The base station and the terminal agree on P in formula (1). CMAX,f,c (i) satisfies the following formula (2):

[0063] P CMAX_L，f，c ≤P CMAX，f，c ≤P CMAX_H，f，c (2)

[0064] in

[0065] P CMAX_L，f，c =MIN{PEMAX，c –ΔTC,c,(P PowerClass –ΔP PowerClass )–MAX(MPR c +A-MPR c +ΔT IB，c +Δ TC，c , P-MPR c )} (3-1)

[0066] P CMAX_H，f，c =MIN{P EMAX，c , P PowerClass –ΔP PowerClass} (3-2)

[0067] The specific meaning of each parameter can be found in Protocol 38.101-1. CMAX,f,c (i) As long as the range in the above formula (2) is satisfied, P CMAX,f,c (i) The specific value depends on the terminal selection. When the trigger condition is met, the terminal will select P CMAX,f,c (i) The value is reported to the base station.

[0068] On the other hand, when the trigger condition is met, the terminal reports the power headroom information to the base station, where the power headroom information can be expressed in one of the following formulas (3-3) to (3-6):

[0069]

[0070]

[0071]

[0072]

[0073] For the specific meaning of each parameter, please refer to Protocol 38.213 and Protocol 38.101-1.

Technical effect.

[0392] In certain implementations, determining associated power information using channels and signals between communication nodes can achieve technical effects including but not limited to better power control and improved power utilization efficiency.

[0393] Specific application example 1

[0394] In this embodiment, if the power control system for reporting NR continues to be used in the IAB system, the IAB donor node / IAB node1 will not consider the transmit power of channels or signals in the DA frequency-division multiplexing and / or space-division multiplexing with the UB-PUSCH (Physical Uplink Shared Channel) when allocating the power information of the UB-PUSCH. To this end, the following enhancement scheme can be adopted:

[0395] Option 1: Figure 1 The IAB node2 in the IAB donor node / IAB node1 requests or feeds back the power information of the UB-PUSCH that the IAB node2 wants, wherein the request information sent by the IAB node2 includes at least one of the following information of the UB-PUSCH / UB-PUCCH / UB-SRS: target power P O_PUSCH,b,f,c (j), path loss adjustment factor α b,f,c (j) Downlink reference signal q for calculating path loss reference d , power adjustment parameter δPUSCH,b,f,c One thing that needs to be explained is that the target power P O_PUSCH,b,f,c (j) By P O_NOMINAL_PUSCH,f,c (j), P O_UE_PUSCH,b,f,c (j) consists of two parts, P O_NOMINAL_PUSCH,f,c (j) is the cell-specific parameter, P O_UE_PUSCH,b,f,c (j) It is UE-specific, and each UE's BWP can be different. Since the cell-specific power parameter needs to take into account all UEs covered by the IAB donor node / IAB node1 under this CC, it is difficult for the IAB donor node / IAB node1 to adjust even if the IAB node2 requests it. Therefore, it is preferable that the IAB node2 can request the UE-specific parameter P from the base station. O_UE_PUSCH,b,f,c (j) IAB node2 is a special terminal in the eyes of IAB donor node / IABnode1. IAB node2 can request a P for each BWP. O_UE_PUSCH,b,f,c (j) You can also request only the P of the currently activated BWP O_UE_PUSCH,b,f,c (j) Parameters.

[0396] Optionally, when IAB node2 requests or feeds back UB-PUSCH power information to IAB donor node / IAB node1, it may request or feed back two sets of power information, wherein the UB-PUSCH power information acquisition parameters in the first set do not include the power information of the DA channel or signal, and the UB-PUSCH power information acquisition parameters in the second set include the power information of the DA channel or signal.

[0397] Solution 2: IAB node 2 sends power information of channels or signals in the DA to the IAB donor node / IAB node 1. Preferably, the DA is a DA that is spatially multiplexed or frequency-division multiplexed with the UB. The power information of the channels or signals in the DA includes at least one of the following information: transmit power, target received power, RSRP (reference signal received power) information of the DA's reference signal arriving at the IAB node 3 / UE, RSRQ (reference signal received quality) information of the DA's reference signal arriving at the IAB node 3 / UE, CSI (channel state information) information of the DA's reference signal arriving at the IAB node 3 / UE, RSRP / RSRQ of the DA's reference signal arriving at the IAB node 3 / UE, and target received power P of the UB signal allocated by the IAB donor node / IAB node 1 at the IAB donor / IAB node 1. O_PUSCH,b,f,c For example, UB and DA share the power amplifier of IAB node 2, and UB and DA are multiplexed by digital beam space division. If the DA reference signal reaches Figure 1 If the performance of IAB node3 / UE is better, IAB donor node / IABnode1 can adjust the transmit power of UB according to the receiving performance of DA at IAB node3 / UE (for example, adjust the acquisition parameters of UB transmit power through signaling), thereby ensuring the spatial division multiplexing of DA and UB while reducing the mutual interference between the two signals. Figure 1 The IAB node2 in the figure can be seen as two downlink users doing MU, and their interference needs to be considered. However, the UB signal is generated by Figure 1 The IAB donor node / IAB node1 in the control scheduling, DA is controlled by Figure 1 Therefore, IAB node2 needs to feed back the DA power control information to IAB donor node / IAB node1.

[0398] In the above-mentioned options 1 and 2, Figure 1After the IAB node2 feeds back or requests the above information to the IAB donor node / IAB node1, the IAB donor node / IAB node1 can adjust the power of the UB-PUSCH with reference to the information and allocate power control information to the UB-PUSCH, and / or the IAB donor node / IAB node1 and the IAB node2 can agree with the IAB node2 that the IAB node2 can obtain the transmission power of the UB-PUSCH according to the feedback information.

[0399] Solution 3: IAB node 2 calculates P in formula (2) CMAX，f，c When considering the impact of DA,

[0400] For example, when the above formula (3-1) is changed to (4-1) and / or formula (3-2) is changed to (4-2):

[0401] P CMAX_L，f，c =MIN{P EMAX，c –ΔTC,c,(P PowerClass –ΔP PowerClass )–MAX(MPR c +A-MPR c +ΔT IB，c +Δ TC，c+ P DA , P-MPR c )}(4-1);

[0402] P CMAX_H，f，c =MIN{P EMAX，c , P PowerClass –ΔP PowerClass -P DA} (4-2).

[0403] Among them, P DA is the transmit power of the DA channel or signal on the time domain resource where the UB-PUSCH is located. IAB node2 obtains P according to formula (2), formula (3-1) and (4-2): CMAX，f，c , or IAB node2 obtains P according to formula (2) and formula (4-1) and (3-2) CMAX，f，c , or IAB node2 obtains P according to formula (2) and formulas (4-1) and (4-2) CMAX，f，c When the reporting conditions are met, IAB node2 will select P CMAX，f，c The value is reported to IAB donor / IAB node1.

[0404] Solution 4: When IAB node 2 calculates the power headroom (Power headroom PH) according to one of formulas (3-3) to (3-6), it considers the influence of the DA signal. For example, formula (3-3) can be changed to formula (4-3):

[0405]

[0406] And / or change formula (3-4) to formula (4-4)

[0407]

[0408] And / or change formula (3-5) to formula (4-5)

[0409] PH type3,b,f,c (i,q s ,l)=P CMAX,f,c (i)-{P O_SRS,b,f,c (q s )+10log 10 (2 μ ·M SRS,b,f,c (i))+α SRS,b,f,c (q s )·PL b,f,c (q d )+h b,f,c (i,l)+P DA} (4-5)

[0410] And / or change formula (3-6) to formula (4-6)

[0411]

[0412] Solution 5: When calculating the UB-PUSCH power, IAB node 2 changes formula (1) to formula (5-1)

[0413]

[0414] Among them, P DA It is the total transmit power of the DA channel and / or signal on the PRB where the DA channel and / or signal is located in the time domain resource where the UB-PUSCH is located, such as P DA It can be obtained by one of the following formulas:

[0415]

[0416] P DA =f(PRB DA ), (5-3)

[0417] P DA =f1(PRBDA,c ,DA CC ), (5-4)

[0418]

[0419] Among them PRB DA It is the PRB set where the DA channel or signal exists on the time domain symbol where the UB is located, or the PRB DA It is the PRB occupied by the DA channel and / or signal in the bandwidth of the power amplifier shared with UB power, specifically, PRB DA Includes an IntraBand or a CC or a PRB with DA channels and / or signals in a BWP. DA,r is on the rth PRB Figure 1 The transmit power of the DA channel and / or signal sent by the IAB node2 in the DA,r is the rth PRB on a time domain symbol Figure 1 The transmit power of the DA channel and / or signal sent by the IAB node2. Indicates the number of PRBs included in CC c where DA is located. When there is no DA signal to be sent in a PRB r in CC c where DA is located in the time domain symbol where UB is located, P DA,r,c The above DA channel and / or signal may be sent to multiple UEs / IAB nodes 3 under the coverage of IAB node 2, or to one UE / IAB node 3. DA ) is about PRB DA Function, f1(PRB DA,c ,DA CC ) is about PRB DA,c ,DA CC function, where c∈DA CC ,DA CC It is the set of CCs where DA channels and / or signals exist on the time domain symbol where UB is located.

[0420] Solution 6: The power of UB and DA is calculated separately. When the total power of the two is greater than the agreed value, the power of UB and / or DA is reduced using the agreed method. For the specific implementation method, please refer to the embodiment 3.

[0421] The above scheme describes the power control method of UB-PUSCH. Similarly, the above scheme is also applicable to the power control of UB-PUCCH (Physical Uplink Control Channel) and UB-SRS (Sounding Reference Signal).

[0422] Specific application example 2

[0423] In this embodiment, the power determination method is determined according to at least one of the following methods: received signaling information, sent request information, multiplexing method between A links, whether the frequency domain resources occupied by channels or signals in A links overlap, agreed rules, and the relationship between the total power of channels or signals in B links and a predetermined value, where A and B are positive integers greater than 1.

[0424] Specifically, for example, the power acquisition method of the UB link has the following two formulas (6-1) and (6-2). The specific formula to be used is obtained based on at least one of the following information: the request information sent by IABnode2 to the IAB donor node / IAB node1, the signaling information sent by the IAB donor node / IAB node1 to the IAB node2, the multiplexing method information between the UB and the DA, whether there is overlap between the PRB resources occupied by the UB channels or signals and the PRB resources occupied by the DA channels and / or signals, and the agreed rules.

[0425]

[0426]

[0427] Among them, P DA It is the total transmit power of the DA channel and / or signal on the PRB where the DA channel and / or signal is located in the time domain resource where the UB-PUSCH is located, such as P DA It can be calculated using one of the formulas (5-2) to (5-5).

[0428] When UB and DA are frequency-division multiplexed, only the total power of UB is affected by the transmit power of DA. When UB and DA are space-division multiplexed, not only is the total power of UB affected by the transmit power of DA, but if the total power of the channel and / or signal transmitted by IAB node 2 in each PRB is to be kept constant, the available power of each PRB of UB is also affected by DA. Therefore, the influence of DA must also be considered in the power calculation of each PRB of UB in formula (6-2), as follows: Figure 8 As shown, it is a schematic diagram of UB-PUSCH and DA channels and / or signals. UB-PUSCH occupies {PRB1, PRB2, PRB3}. On the time domain symbol where UB-PUSCH is located, the PRBs of the channels or signals with DA are {PRB1, PRB3, PRB4 to PRB8}. DAWhen calculating the transmit power of each PRB of UB-PUSCH, the transmit power occupied by the channel and / or signal of DA on the PRB can be considered. Indicates the power of the DA channel and / or signal in {PRB1, PRB2, PRB3} occupied by UB-PUSCH, such as It can be one of the following: the minimum value of the DA channel and / or signal in {PRB1, PRB2, PRB3}, the maximum value of the DA channel and / or signal in {PRB1, PRB2, PRB3}, the average value of the DA channel and / or signal in {PRB1, PRB2, PRB3}, or the power of the DA channel or signal in a predetermined PRB in {PRB1, PRB2, PRB}, such as the power of the DA in the lowest PRB ID, such as the power of the DA channel or signal in PRB1. In short, on multiple PRBs occupied by UB at this time, There is only one value.

[0429] In another implementation of this embodiment, formula (6-2) can be changed to formula (6-3), that is, the transmission power of UB-PUSCH is obtained according to at least one of the following information: the request information sent by IAB node2 to IAB donor node / IAB node1, the signaling information sent by the IAB donor node to IAB node2, the multiplexing mode information between UB and DA, and whether there is overlap between the PRB resources occupied by the channels or signals of UB and the PRB resources occupied by the channels and / or signals of DA.

[0430]

[0431] Among them, P DA,r Indicates the transmit power of the DA channel and / or signal in the rth PRB where the UB-PUSCH is located. When there is no DA channel or signal in this PRB, P DA,r 0. That is, at this time, UB occupies multiple PRBs, P DA,r are different values.

[0432] The multiple PRBs (Physical resource blocks) occupied by UB-PUSCH can also be divided into multiple physical resource groups, with For a value, in different physical resource groups, For different values, change formula (6-3) to formula (6-4):

[0433]

[0434] Among them, P DA,g It is the average power of the DA channel or signal in the g-th physical resource block occupied by UB-PUSCH, or the maximum power of the DA channel or signal, or the minimum power of the DA channel or signal.

[0435] The division of physical resource blocks can be Figure 1 The IAB donor / IAB node 1 notifies IAB node 2 via signaling information, and / or the IAB donor / IAB node 1 and IAB node 2 determine the physical resource block division based on an agreed rule. For example, contiguous frequency domain resource blocks occupied by UB-PUSCH belong to one physical resource block group, while non-contiguous frequency domain resource blocks belong to different physical resource block groups. Optionally, a physical resource block group includes one or more physical resource blocks.

[0436] The above-mentioned UB-PUSCH power acquisition method can be similarly used in UB-PUCCH and UB-SRS power acquisition.

[0437] In another implementation of this embodiment, the communicating parties may agree to determine the UB-PUSCH power using one of the above formulas. For example, the IAB donor node / IAB node1 and IAB node1 agree to use formula (6-1) to determine the UB-PUSCH power.

[0438] In another embodiment of this embodiment, the UB-PUSCH power determination method is determined based on the relationship between the sum of the power of the channels or signals in B links and the predetermined value. When the sum of the transmit power of UB and DA is less than or equal to the predetermined value, the transmit power of UB-PUSCH is determined using formula (1). When the sum of the transmit power of UB and DA is greater than the predetermined value, the transmit power of UB-PUSCH is determined using formula (6-1). Alternatively, when the sum of the transmit power of UB and DA is greater than the predetermined value, the transmit power of UB-PUSCH is determined using one of formulas (6-1) and (6-4) according to the above method.

[0439] The above method for determining the power of UB-PUSCH can be similarly used to determine the power of UB-PUCCH and UB-SRS.

[0440] Specific application example three

[0441] In this embodiment, Figure 1The IAB donor / IAB node1 and IAB node2 agree that the sum of the first product and the second product does not exceed a predetermined threshold, where the first product is the product of the UB's transmit power and the first weight, and the second product is the product of the DA's transmit power and the second weight, that is, the following formula needs to be satisfied: where the weight can also be called a power scaling factor.

[0442]

[0443] Where 0≤w(1)≤1, 0≤w(2)≤1, is the linear value of the transmit power of UB, is the linear value of the transmit power of UB, It's P powerclass The linear value, P powerclass is the power level of IAB node2.

[0444] Further, including multiple channels or signals in multiple CCs / BWPs on UB, Includes multiple channels or signals in multiple CCs / BWPs on DA.

[0445] For example, the transmit power of UB-PUSCH is obtained using formula (1) or formula (6-6).

[0446]

[0447] When the sum of the UB-PUSCH power and the DA power is greater than a predetermined value, the UB and DA powers are reduced according to the agreed ratio. In formula (6-5), w(1) and w(2) can be the same value or different values.

[0448] In formula (6-5), when the sum of the powers of UB and DA is greater than a predetermined value, the power reduction ratios of all channels or signals in UB are the same, and the power reduction ratios of all channels or signals in DA are the same. In another implementation of this embodiment, when the sum of the powers of UB and DA is greater than a predetermined value, the power reduction ratios of different channels or signals in UB are different. For example, the reduction factor of the control channel is relatively large, where a larger reduction factor indicates a weaker power reduction. For example, when the sum of the transmit powers of UB and DA is greater than an agreed value, the transmit powers of UB and DA are reduced as shown in (6-7):

[0449]

[0450] where 0≤w UB(i)≤1 represents the power reduction factor for the UB-PUSCH channel. The smaller the power reduction factor, the greater the degree of power reduction. DA (i)≤1 represents the power reduction factor for the DA-PDSCH channel. UB Indicates the presence of UB-PUSCH carrier, C DA Indicates that there is a UB-PUSCH carrier. Alternatively, when the sum of the transmit power of UB and DA is greater than the agreed value, the transmit power of UB and DA is reduced as shown in (6-8):

[0451]

[0452] Here, j is the component carrier where the PUSCH containing the UCI is located. In the above description, the power is described based on CC as a unit. Of course, this embodiment does not exclude the use of BWP (Band width part) as a unit for power control.

[0453] In the above description, is the linear value of P.

[0454] Specific application example 4

[0455] To control interference between DB and UA when they are spatially multiplexed, or even frequency-division multiplexed, if the power reaching IABnode2 differs significantly between DB and UA, the frequency-domain leakage of DB will cause strong interference to the UA channel. Therefore, the power between DB and UA must be controlled, or the sum of their received powers must not exceed a predetermined value. Otherwise, the linear region of power control will be exceeded. Therefore, the power of DB and UA must be comprehensively considered.

[0456] Solution 1: IAB node 2 feeds back UA channel and / or signal power information to IAB donor / IAB node 1. This UA channel and / or signal power information includes at least one of the following: target receive power, maximum transmit power, power headroom, reference signal for path loss calculation, path loss adjustment factor, power schedule, and power adjustment amount. After receiving the UA power parameters, IAB donor / IAB node 1 adjusts the transmit power of the DB channel or signal accordingly, thereby minimizing interference between the DB and UA. Preferably, the UA channel or signal corresponding to the feedback information is spatially and / or frequency-division multiplexed with the DB channel or signal, meaning that the UA and DB occupy the same time instant, or the same PRB within the same time instant, or the time domain resources occupied by the UA and DB do not overlap.

[0457] In the above feedback scheme, when IAB node2 feeds back UA power information, different UA users, or different UAs of the same user, may transmit different beams, resulting in different UA power information. To address this issue, one approach is to feed back cell-specific UA power information for all users covered by IAB node2. Another approach is to feed back different UA power information based on different time domain resources and / or frequency domain resources.

[0458] Of course, IAB node 2 can feedback multiple sets of UA power information, each set of power information corresponds to a reference signal of the UA, or each set of power information corresponds to a reference signal of the DB, indicating the power information of the UA on the time domain resources and / or frequency domain resources where the reference signal of the DB is located.

[0459] Solution 2: IAB node2 feeds back the difference between the UA's power information (e.g., the UA's target received power) and the RSRP of the DB's reference signal to the IAB donor / IABnode1. Upon receiving this difference, IAB donor / IAB node1 determines the power difference between the DB and UA reaching IAB node2 and can adjust the DB's power accordingly. However, since the UA's target power for different IAB nodes3 / UEs and / or for different beams of the same IAB node3 / UE may vary, and DBs may have multiple reference signals, one solution is to feed back the difference between the target received power of a predetermined characteristic of the UA's multiple transmit beams and the RSRP of a predetermined characteristic of the DB's multiple reference signals. The predetermined characteristic can be the maximum, minimum, or median value among multiple values. Another solution is to feed back a combination of (DB's reference signal index and UA's transmit beam index) information when feeding back the difference. The third feedback scheme is to feedback a set of difference information for different time domain resources and / or frequency domain resources. Preferably, one time domain resource and / or frequency domain resource corresponds to a reference signal set for a DA and / or a transmit beam set for a UA. In this article, the transmit beam of a UA can be represented by a reference signal index of the UA.

[0460] Solution 3: IABnode2 requests DB power information. The DB power information includes at least one of the following: the transmit power of DB (i.e., the first channel or signal) sent by IABdonor / IAB node1; the receive power of DB arriving at IAB node2 (i.e., the first communication node); the difference between the receive power of DB arriving at IABnode2 and the target receive power of DB arriving at IABnode2;

[0461] Solution 4: IABnode2 feeds back one or more of the UA's transmit power acquisition parameters to the IAB donor / IABnode1, where the UA's transmit power acquisition parameters may include one or more of the following: the number of PRBs occupied by the UA, the UA's subcarrier spacing, the relationship between the UA's subcarrier spacing and the DB's subcarrier spacing, the number of time-domain symbols occupied by the UA, the number of PRBs included in the intersection between the PRB set occupied by the UA and the PRB set occupied by the DB, and the number of time-domain symbols included in the intersection between the time-domain symbol set occupied by the UA and the time-domain symbol set occupied by the DB.

[0462] Specific application example 5

[0463] In the above embodiment, the power of UB and DA, and / or the power of DB and UA, needs to be considered comprehensively. In particular, UB and DA share a set of transmit antennas at IAB node 2. UB and DA are spatially multiplexed using digital beamforming, and similarly, DB and UA receive spatially multiplexed using digital beamforming. However, if both are spatially multiplexed using different panels and independent power amplifiers are used between the two panels, the power of UB and DA does not need to be considered comprehensively from a power-constrained perspective. Similarly, the power of DB and UA does not need to be considered comprehensively from a power-constrained perspective in this scenario.

[0464] To this end, we first determine whether the two links are independent power amplifiers. Based on whether they are independent power amplifiers, we determine whether the power of the two links needs to be comprehensively considered. Whether there is an independent panel is related to at least one of the following information: whether UB and DA share power at the first communication node; whether the sum of the transmit power of UB and DA needs to be less than a first predetermined value. If it is less than the first predetermined value, it means that the shared power amplifier or the total power needs to be limited; whether the sum of the receive power of UB and DA needs to be less than a second predetermined value; whether the component carrier where the first type of channel or signal is located and the CC where the second type of channel or signal is located belong to the same frequency band.

[0465] Figure 1 The IAB node2 may also feed back at least one of the above information reflecting whether the power of UB and DA needs to be comprehensively considered to the IAB donor / IAB node1.

[0466] Specific application example 6

[0467] In this embodiment, the power of an uplink channel or signal in multiple time-domain symbols within a time unit may be different. Specifically, the power of an uplink channel and / or signal in multiple time-domain symbols within a slot may be different. In this embodiment, a time unit is a slot, but a time unit may also be multiple slots occupied by an uplink channel or signal corresponding to a single scheduling operation.

[0468] In the aforementioned embodiments, it is generally assumed that the time domain resources occupied by the UB channel or signal and the DA channel and / or signal overlap, or that the transmit power of the UB channel or signal in multiple time domain symbols occupied by the UB channel or signal is the same. In this embodiment, since the UB channel or signal and the DA channel or signal may only partially overlap in the time domain, in order to fully utilize the transmit power of the IAB node, it is necessary to consider that different time domain symbol groups within the multiple time domain symbols occupied by the UB channel or signal can have different transmit powers.

[0469] For example, multiple time domain symbols occupied by a UB channel or signal include C time domain symbol sets, each of the C time domain symbol sets is associated with a set of power information, and C is a positive integer greater than 1.

[0470] like Figure 9 As shown, the 4 time domain symbols occupied by UB-PUSCH are divided into 2 time domain symbol sets, such as Figure 9 As shown, the four time domain symbols {n1, n2, n3, n4} occupied by UB-PUSCH are divided into two time domain symbol sets {n1, n2} and {n3, n4}. On the {n1, n2} time domain symbols, IAB node2 needs to send UB and DA signals. On the {n3, n4} time domain symbols, IAB node2 only needs to send UB and does not need to send DA channels and / or signals.

[0471] The following solutions are possible for this purpose:

[0472] Solution 1: Calculate P CMAX_L，f，c Consider the influence of DA when updating formula (4-1) to formula (7-1)

[0473] P CMAX_L，f，c，tj =MIN{P EMAX，c –ΔTC,c,(P PowerClass –ΔP PowerClass )–MAX(MPRc +A-MPR c +ΔTIB ，c +Δ TC，c+ P DA,tj , P-MPR c )} (7-1)

[0474] Where tj=0,1,...C-1,P CMAX_L，f，c，tj is the maximum power corresponding to UB-PUSCH in the tjth time domain symbol set. And / or update formula (4-2) to formula (7-2):

[0475] P CMAX_H，f，c，tj =MIN{P EMAX，c , P PowerClass –ΔP PowerClass -P DA,tj} (7-2)

[0476] Solution 2: Consider the impact of DA when calculating PHR (power headroom) and update formula (4-3) to formula (7-3)

[0477]

[0478] And / or change formula (4-4) to formula (7-4)

[0479]

[0480] And / or change formula (4-5) to formula (7-5)

[0481]

[0482] And / or change formula (4-6) to formula (7-6)

[0483]

[0484] where tj=0,1,...C-1, PH is the type 1 power margin on the tjth time domain symbol set. type3,b,f,c (i,q s ,l,tj), is the type3 power margin on the tjth time domain symbol set.

[0485] Solution 3: When calculating the transmit power of UB-PUSCH, consider the impact of DA. This allows formula (5-3) or formula (6-1) to be updated to formula (7-7):

[0486]

[0487] And / or update formula (6-2) to formula (7-8)

[0488]

[0489] And / or update formula (6-3) to formula (7-9)

[0490]

[0491] And / or update formula (6-4) to formula (7-10)

[0492]

[0493] where tj=0,1,...C-1,X tj is the number of physical resource block groups of UB-PUSCH on the tj-th time domain symbol set, g tj is the gth UB-PUSCH on the tjth time domain symbol set tj P PUSCH,b,f,c (i,j,q d ,l,tj) is the transmit power of UB-PUSCH on the tj-th time domain symbol set. Preferably, the transmit power of UB-PUSCH on multiple time domain symbols included in a time domain symbol set is the same. For example, on each time domain symbol in the tj-th time domain symbol set, the transmit power of UB-PUSCH is P PUSCH,b,f,c (i,j,q d ,l,tj). Formula (7-10) assumes that the division of the frequency-domain resource block groups for UB is different for different time-domain symbol sets. Of course, this embodiment does not exclude the possibility that the division of the frequency-domain resource block groups for UB is the same for different time-domain symbol sets tj. That is, Formula (7-10) is updated to Formula (7-11). The above-mentioned time-domain symbol set includes one or more time-domain symbols.

[0494]

[0495] The above P DA,tj It represents the transmit power of the DA corresponding to the tj-th time domain symbol set of UB-PUSCH. Different time domain symbol sets correspond to different DA transmit powers, such as Figure 9 As shown, P DA,0 is the transmit power of DA in the {n1, n2} time domain symbol set, P DA,1 is the transmit power of DA in the {n3, n4} time domain symbol set. Since there is no DA channel and / or signal in the {n3, n4} time domain symbol set, P DA,1 Preferably, the transmission power of multiple time domain symbols of the DA corresponding to the tj-th time domain symbol set of UB-PUSCH is the same, such as Figure 9 As shown, the transmission power of DA on the two time domain symbols {n1, n2} is the same. When the transmission power of DA on {n1, n2} is different, P DA,0 The maximum value, minimum value, or average value in the time domain symbol {n1, n2} can be taken, or the value obtained according to the agreed rules based on the transmission power of the DA in {n1, n2} can be taken.

[0496] When the subcarrier spacing of UB and DA is different, and thus the time domain symbol length is different, P DA,tj Indicates the transmission power of DA converted into the transmission power of one time domain symbol of UB. Figure 10 As shown, a UB time domain symbol includes multiple DA time domain symbols, then P DA,tj =2 -μ P DA,tj,15KHz , 2 μ *15KHz is the subcarrier spacing of UB-PUSCH. DA,tj,15KHz It is the transmit power of one time domain symbol of DA obtained with a subcarrier spacing of 15KHz.

[0497] P DA,,r,tj Indicates the number of UB-PUSCHs in the tjth time domain symbol set where UB-PUSCH is located. The transmit power of the DA in the rth PRB among the PRBs, Indicates the number of UB-PUSCHs in the tjth time domain symbol set where UB-PUSCH is located. Multiple transmit powers of DA in PRB, UB-PUSCH occupies Each DA in each of the PRBs has a transmit power, It can be the minimum value, maximum value, average value, median value of the DA transmission power in these multiple PRBs, or the power of the DA in a predetermined PRB, or a value obtained based on the DA transmission power in these multiple PRBs and an agreed function. is the gth symbol in the tjth time domain symbol set tj The transmit power of the DA in the physical resource block group, where each PRB in each time domain symbol in the tj-th time domain symbol set has a transmit power of a DA, so that the physical resource block in this time domain symbol set can have multiple DA transmit powers. The transmit power of the DA that meets the predetermined characteristics among the multiple transmit powers, such as the maximum value, minimum value, median value, average value, the transmit power of the DA in the predetermined PRB predetermined time domain symbol, or It is obtained based on the multiple transmission powers and a predetermined function.

[0498] In various embodiments of the present invention, a time unit may be one of the following: a slot, a length of T time domain symbols, a length of T time domain symbols obtained from a reference subcarrier, where T is a positive integer. One time domain symbol may be an OFDM symbol.

[0499] Specific application example seven

[0500] In this embodiment, one reference signal resource indication information is associated with multiple sets of power information. For example, one SRI (Sounding resource indication) is associated with multiple sets of power information. One of the multiple sets of power information is selected through signaling information or agreed rules.

[0501] For example, RRC signaling configures multiple sets of power information for an SRI, where each set of power information includes at least one of the following information: target power P O_PUSCH,b,f,c (j), path loss adjustment factor α b,f,c (j) Downlink reference signal q for calculating path loss reference d , power adjustment parameter δ PUSCH,b,f,c Then MAC-CE signaling activates one of the two sets for SRI. Alternatively, DCI can activate one of the two sets for SRI.

[0502] Alternatively, according to agreed rules, the power information of the SRI at different time unit sets is one of the multiple sets of power information. For example, the power of the SRI at {slot2k+1, k=0, 1, 2...} is the first set of power information, and the power of the SRI at {slot2k, k=0, 1, 2...} is the second set of power information.

[0503] Optionally, the power information associated with the SRI is determined based on the TA information corresponding to the SRI. For example, if one SRI is associated with two sets of power information and two TA values, when it is determined that the power information of the SRI is obtained based on one of the two sets of power information, it can also be determined which of the two TAs the SRS corresponding to the SRI is transmitted in. The TA is the advance amount of the uplink signal transmission relative to the downlink timing.

[0504] Optionally, the power information of the SRI is determined based on the CORESET (Control resource set, i.e., control channel resource) where the DCI (Downlink control information) that schedules the SRI is located. According to which of the two sets of power information is obtained, for example, when the DCI is in CORESET1, the power information of the SRI is obtained based on the first set of power information. For example, when the DCI is in CORESET2, the power information of the SRI is obtained based on the second set of power information.

[0505] Similarly, the TA information of the SRI is obtained based on the CORESET where the DCI that schedules the SRI is located. For example, when the DCI is in CORESET1, the TA information of the SRI is obtained based on the first set of TA information. For example, when the DCI is in CORESET2, the TA information of the SRI is obtained based on the second set of TA information.

[0506] The above is to determine the power / TA information associated with an SRI based on the CORESET. Of course, it is also possible to establish an association between the CORESET group where the CORESET is located and the power / TA information. For example, CORESET group 1 is associated with the first set of power / TA, and CORESET group 2 is associated with the second set of power / TA. The power / TA selection information is determined according to the CORESET group where the DCI that schedules the SRI is located.

[0507] The above method of associating multiple sets of power information with one reference signal resource indication information can similarly be used to associate multiple sets of power information with one reference signal resource combination indication information. The reference signal can also be a demodulation reference signal or an uplink random access sequence signal.
