本申请涉及移动通信技术领域，尤其涉及一种确定物理上行共享信道发送功率的方法和设备。The present application relates to the field of mobile communication technologies, and in particular, to a method and device for determining the transmit power of a physical uplink shared channel.
背景技术Background technique
Rel.16的NR系统将支持可靠性要求1×10-6以及时延要求最低在0.5ms以下的URLLC(Ultra-reliable and Low Latency communication)业务。使用PUSCH重复传输，一方面可提高传输可靠性，另一方面可满足接收设备尽早获取到PUSCH初始解调结果的要求。The NR system of Rel.16 will support the URLLC (Ultra-reliable and Low Latency communication) service with a reliability requirement of 1×10-6 and a minimum delay requirement below 0.5ms. Using PUSCH for repeated transmission, on the one hand, can improve the reliability of transmission, and on the other hand, it can meet the requirement of the receiving device to obtain the initial demodulation result of the PUSCH as soon as possible.
网络设备通过调度指示需要N个重复发送的上行数据信道，并且调度指示这些上行数据信道中不包括UL-SCH。在传输时，由于跨时隙的上行数据信道被时隙边界分割，导致实际传输的PUSCH被分为M个(M>N)、每个实际传输的PUSCH中包括的时间符号的个数不尽相同，也就是每个“实际PUSCH”中用于上行控制信息(UCI)的资源可能不同。The network device indicates through the scheduling that N uplink data channels to be sent repeatedly, and the scheduling indicates that these uplink data channels do not include the UL-SCH. During transmission, since the uplink data channel across time slots is divided by the time slot boundary, the actually transmitted PUSCH is divided into M (M>N), and the number of time symbols included in each actually transmitted PUSCH is infinite. The same, that is, the resources used for uplink control information (UCI) in each "actual PUSCH" may be different.
如果实际PUSCH中用于UCI传输的资源数量不同，则传输UCI的编码速率不同。按照现有技术确定PUSCH发送功率的方式，发送功率调整量ΔTF，b，f，c(i)的取值仅和Qm、R和
编码速率不同但发送功率相同，导致M个实际PUSCH传输的UCI的解调性能不同。特别是，有可能部分实际PUSCH传输性能远高于需求、部分实际PUSCH传输性能远低于需求，也就是说，UCI的性能在重复PUSCH上不均衡。为满足UCI传输性能需求，基站不得不调度过多的PUSCH资源，最终造成UCI接收性能较差、系统效率较低。Different coding rates but the same transmit power result in different demodulation performances of UCIs transmitted by M actual PUSCHs. In particular, it is possible that some of the actual PUSCH transmission performance is much higher than the requirement, and some of the actual PUSCH transmission performance is much lower than the requirement, that is, the performance of the UCI is not balanced on the repeated PUSCH. In order to meet the UCI transmission performance requirements, the base station has to schedule too many PUSCH resources, which ultimately results in poor UCI reception performance and low system efficiency.

具体实施方式Detailed ways
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below with reference to the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
本发明的构思是，各PUSCH的发送功率调整量中体现可用于传输目标UCI的资源不同的因素。可用于传输UCI的资源越多，该PUSCH所对应的发送功率调整量越小。可用于传输UCI的资源越少，该PUSCH所对应的发送功率调整量越大。这样，可调整每次PUSCH的发送功率，以满足UCI的性能要求，并且避免系统效率低下的问题。The concept of the present invention is that the transmission power adjustment amount of each PUSCH reflects the different factors of resources available for transmitting the target UCI. The more resources available for UCI transmission, the smaller the transmission power adjustment amount corresponding to the PUSCH. The fewer resources available for UCI transmission, the greater the amount of transmission power adjustment corresponding to the PUSCH. In this way, the transmission power of each PUSCH can be adjusted to meet the performance requirements of UCI, and to avoid the problem of low system efficiency.
以下结合附图，详细说明本申请各实施例提供的技术方案。The technical solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.
图1为实际的PUSCH长度受时隙边界影响的示意图。FIG. 1 is a schematic diagram illustrating that the actual PUSCH length is affected by the slot boundary.
为满足URLLC业务的时延和可靠性要求，NR系统引入PUSCH的重复传输方式。网络设备通过调度指示终端设备重复发送N次上行数据信道(以下称为“名义PUSCH”)。调度信息中还包括“名义PUSCH”占用符号的时间位置和符号个数。例如，调度信息中包括第一个“名义PUSCH”的符号位置和个数，终端设备即可确定多个“名义PUSCH”各自在时间上占用的符号位置和符号个数。如果一次“名义PUSCH”跨越了时隙边界，则实际传输时，该“名义PUSCH”以时隙边界为界分为两次“实际PUSCH”；另外，如果一次“名义PUSCH”包括被指示为下行的符号，则该“名义PUSCH”也会以该符号为界分为两次“实际PUSCH”。In order to meet the time delay and reliability requirements of URLLC services, the NR system introduces the repeated transmission mode of PUSCH. The network device instructs the terminal device to repeatedly transmit the uplink data channel (hereinafter referred to as "nominal PUSCH") for N times through scheduling. The scheduling information also includes the time position and the number of symbols occupied by the "nominal PUSCH". For example, the scheduling information includes the symbol position and number of the first "nominal PUSCH", and the terminal device can determine the symbol position and the number of symbols occupied by each of the multiple "nominal PUSCH" in time. If a "nominal PUSCH" crosses the time slot boundary, during actual transmission, the "nominal PUSCH" is divided into two "real PUSCH" with the time slot boundary as the boundary; symbol, the "nominal PUSCH" will also be divided into two "actual PUSCH" with the symbol as the boundary.
如图1所示，网络设备指示的重复次数为3次，第一次“名义PUSCH”在时间上位于时隙#n中第5个符号到第12个符号。基于此，终端设备可确定第二次“名义PUSCH”在时间上位于时隙#n中第13个符号到时隙#n+1中第6个符号，第三次“名义PUSCH”在时间上位于时隙#n+1中第7个符号到时隙#n+1中第14个符号。由于第二次“名义PUSCH”在时间上跨越了时隙#n和时隙#n+1之间的时隙边界，则第二次“名义PUSCH”以该时隙边界为界，分为两次“实际PUSCH”，分别位于时隙#n中第13个符号到时隙#n中第14个符号、时隙#n+1中第1个符号到时隙#n+1中第6个符号。这样终端设备分别在第一次“实际PUSCH”、第二次“实际PUSCH”、第三次“实际PUSCH”、第四次“实际PUSCH”发送信号。As shown in FIG. 1 , the number of repetitions indicated by the network device is 3, and the first “nominal PUSCH” is located in time from the 5th symbol to the 12th symbol in time slot #n. Based on this, the terminal device can determine that the second "nominal PUSCH" is located in time from the 13th symbol in time slot #n to the 6th symbol in time slot #n+1, and the third "nominal PUSCH" is temporally located in time slot #n+1. From the 7th symbol in slot #n+1 to the 14th symbol in slot #n+1. Since the second "nominal PUSCH" spans the slot boundary between slot #n and slot #n+1 in time, the second "nominal PUSCH" is bounded by the slot boundary and divided into two Secondary "actual PUSCH" from the 13th symbol in slot #n to the 14th symbol in slot #n, the 1st symbol in slot #n+1 to the 6th symbol in slot #n+1 symbol. In this way, the terminal device sends signals at the first "actual PUSCH", the second "actual PUSCH", the third "actual PUSCH", and the fourth "actual PUSCH".
终端设备还要根据确定每个实际PUSCH的发送功率。根据3GPP TS38.213V15.6.0，在载波f的服务小区c上，和功率配置集合参数索引j对应的上行BWP(BandWidth Part，带宽部分)b上第i个传输时刻的PUSCH的传输功率的确定公式包括“ΔTF，b，f，c(i)”一项，我们称之为“发送功率调整量”，以下简写为“Δ”，有：The terminal device also needs to determine the transmit power of each actual PUSCH according to. According to 3GPP TS38.213V15.6.0, on the serving cell c of the carrier f, the determination formula of the transmission power of the PUSCH at the i-th transmission time on the uplink BWP (BandWidth Part, bandwidth part) b corresponding to the power configuration set parameter index j Including "ΔTF, b, f, c (i)", we call it "transmission power adjustment", abbreviated as "Δ" below, there are:
KS＝1.25时，
终端设备还根据网络设备在DCI发送的上行调度授权(UL grant)确定发送的PUSCH中是否包括UL-SCH。如果PUSCH中不包括UL-SCH，则：The terminal device also determines whether the sent PUSCH includes the UL-SCH according to the uplink scheduling grant (UL grant) sent by the network device in the DCI. If the UL-SCH is not included in the PUSCH, then:
其中，Qm和R分别调度PUSCH的DCI中调制编码方案的字段指示的调制阶数和目标编码速率。此时PUSCH中传送UCI是以CSI part 1为基础的，取

本申请提出的一种确定物理上行共享信道发送功率的方法，包括以下步骤10～30：A method for determining the transmit power of a physical uplink shared channel proposed in this application includes the following
步骤10、根据调度信息的指示，在M个PUSCH中重复发送UCI，所述M个PUSCH中不包含UL-SCH；
终端设备获取调度信息，根据调度信息，终端设备确定在M个PUSCH中重复发送目标UCI，并且确定该M个PUSCH都不包括UL-SCH。其中，M为正整数，由于是重复传送，能够理解M>1。这里的M个PUSCH，指图1中的“实际PUSCH”。The terminal device acquires scheduling information, and according to the scheduling information, the terminal device determines to repeatedly transmit the target UCI in the M PUSCHs, and determines that none of the M PUSCHs includes the UL-SCH. Among them, M is a positive integer. Since it is repeated transmission, it can be understood that M>1. The M PUSCHs here refer to "actual PUSCHs" in FIG. 1 .
需要说明，NR系统中，PUSCH可以承载终端设备发送的上行共享信道UL-SCH和或上行控制信息UCI。UL-SCH中包括终端设备发送给网络设备的上行业务数据信息。UCI信息包括HARQ-ACK和或CSI。CSI分为CSI part 1和CSI part 2两种。CSI-Part 1指的是负荷大小固定的CSI信息，例如对于类型1的CSI上报，CSI-part 1包括RI、CRI、第一个码字的CQI等；对于类型2的CSI上报，CSI-part 1包括RI、CQI、每层非零宽带幅度等。CSI-Part 2指的是负荷大小根据测量结果不同可变化的CSI信息，例如对于类型1的CSI上报，CSI-part 2包括PMI、第二个码字的CQI等；对于类型2的CSI上报，CSI-part 2包括PMI等。It should be noted that in the NR system, the PUSCH may carry the uplink shared channel UL-SCH and or uplink control information UCI sent by the terminal device. The UL-SCH includes uplink service data information sent by the terminal device to the network device. UCI information includes HARQ-ACK and or CSI. CSI is divided into
所述调度息，例如可以是高层信令，用于配置类型1的PUSCH配置资源。所述调度信息，例如还可以是动态的授权调度，即物理下行控制信息。该物理下行控制信息用于调度或者激活预配置的类型2的PUSCH配置资源。The scheduling information, for example, may be high-level signaling, which is used to configure
步骤20、根据第r(r≤M)个PUSCH中可用于传输UCI的资源数目确定所述第r个PUSCH的发送功率调整量，所述发送功率调整量与所述资源数目负相关。Step 20: Determine the transmission power adjustment amount of the rth PUSCH according to the number of resources available for UCI transmission in the rth (r≤M)th PUSCH, where the transmission power adjustment amount is negatively correlated with the number of resources.
本申请文件中的“负相关”，是指数值变化方向相反，例如发送功率调整量随资源数目增加而减小，或者发送功率调整量随资源数目减小而增加。或者说，如果发送功率调整量表示为所述资源数目的函数，则发送功率调整量对所述资源数目的导数小于0。"Negative correlation" in this application document means that the index value changes in opposite directions, for example, the amount of transmission power adjustment decreases as the number of resources increases, or the amount of transmission power adjustment increases as the number of resources decreases. In other words, if the transmission power adjustment amount is expressed as a function of the number of resources, the derivative of the transmission power adjustment amount with respect to the number of resources is less than 0.
对于如何在发送功率调整量Δ中体现不包括UL-SCH的各PUSCH中可用于传输目标UCI的资源不同，具体方式这里可不作限制。满足发送功率调整量和可用于传输目标UCI的资源负相关即可。As to how to reflect the different resources available for transmitting the target UCI in each PUSCH that does not include the UL-SCH in the transmission power adjustment amount Δ, the specific manner may not be limited here. It suffices to satisfy the negative correlation between the transmission power adjustment amount and the resources available for transmitting the target UCI.
优选地，所述资源数量为第r个PUSCH的传输资源中用于UCI传输的调制符号数量，对于M次“实际PUSCH”中的第r次，其可用于UCI传输的编码后调制符号的数量Qr′为:Preferably, the number of resources is the number of modulation symbols used for UCI transmission in the transmission resource of the rth PUSCH, and for the rth time in M times of "actual PUSCH", the number of coded modulation symbols that can be used for UCI transmission Qr ′ is:
其中
所述根据第r个PUSCH中可用于传输UCI的资源数目确定所述第r个PUSCH的发送功率调整量的步骤，进一步包含步骤21或22，其中，定义一个调整系数，由于M个PUSCH的各自可用于传输UCI的资源数目可能不尽相同，第r个PUSCH的发送功率调整量根据第r个PUSCH的调整系数确定。The step of determining the transmission power adjustment amount of the r-th PUSCH according to the number of resources available for UCI transmission in the r-th PUSCH further includes step 21 or 22, wherein an adjustment coefficient is defined, since each of the M PUSCHs The number of resources available for UCI transmission may vary, and the transmission power adjustment amount of the rth PUSCH is determined according to the adjustment coefficient of the rth PUSCH.
步骤21、根据所述第r个PUSCH中可用于传输UCI的资源数目确定调整系数，其中所述调整系数和所述资源数目正相关；所述调整系数，作用于所述发送功率调整量，所述发送功率调整量与所述调整系数负相关。Step 21: Determine an adjustment coefficient according to the number of resources available for UCI transmission in the rth PUSCH, where the adjustment coefficient is positively correlated with the number of resources; the adjustment coefficient acts on the transmission power adjustment amount, so The transmission power adjustment amount is negatively correlated with the adjustment coefficient.
发送功率调整量与所述调整系数负相关，是指发送功率调整量与所述调整系数数值变化方向相反，例如发送功率调整量随调整系数增加而减小，或者发送功率调整量随调整系数减小而增加。或者说，如果发送功率调整量表示为所述调整系数的函数，则发送功率调整量对所述调整系数的导数小于0。The transmission power adjustment amount is negatively correlated with the adjustment coefficient, which means that the transmission power adjustment amount and the adjustment coefficient value change in the opposite direction, for example, the transmission power adjustment amount decreases as the adjustment coefficient increases, or the transmission power adjustment amount decreases as the adjustment coefficient decreases. small and increasing. In other words, if the transmission power adjustment amount is expressed as a function of the adjustment coefficient, the derivative of the transmission power adjustment amount with respect to the adjustment coefficient is less than 0.
第r个PUSCH的调整系数和所述第r个PUSCH中可用于传输UCI的资源数目正相关。即，可用于传输目标UCI的资源越多，该PUSCH所对应调整系数越大，Δ越小；可用于传输目标UCI的资源越少，该PUSCH所对应调整系数越小，Δ越大。具体地说，第r个PUSCH的调整系数和所述第r个PUSCH中可用于传输UCI的资源数目成正比。The adjustment coefficient of the rth PUSCH is positively correlated with the number of resources available for UCI transmission in the rth PUSCH. That is, the more resources available for transmitting the target UCI, the larger the adjustment coefficient corresponding to the PUSCH and the smaller Δ; the less resources available for transmitting the target UCI, the smaller the adjustment coefficient corresponding to the PUSCH and the larger the Δ. Specifically, the adjustment coefficient of the rth PUSCH is proportional to the number of resources available for UCI transmission in the rth PUSCH.
优选地，所述调整系数为第r个PUSCH的传输资源中用于UCI传输的调制符号数量Qr′；Preferably, the adjustment coefficient is the number of modulation symbols Qr ' used for UCI transmission in the transmission resource of the rth PUSCH;
或者，所述调整系数为第r个PUSCH的传输资源中用于UCI传输的时域符号个数
步骤22、根据所述第r个PUSCH中可用于传输UCI的资源数目确定调整系数，其中所述调整系数和所述资源数目负相关；所述调整系数，作用于所述发送功率调整量，所述发送功率调整量与所述调整系数正相关。Step 22: Determine an adjustment coefficient according to the number of resources available for UCI transmission in the rth PUSCH, wherein the adjustment coefficient is negatively correlated with the number of resources; the adjustment coefficient acts on the transmission power adjustment amount, so The transmission power adjustment amount is positively correlated with the adjustment coefficient.
本申请文件中的“正相关”，是指数值变化方向相同，例如发送功率调整量随调整系数增加而增加，或者发送功率调整量随调整系数减小而减小。或者说，如果发送功率调整量表示为所述调整系数的函数，则发送功率调整量对所述调整系数的导数大于0。The "positive correlation" in this application document means that the index value changes in the same direction, for example, the transmission power adjustment amount increases as the adjustment coefficient increases, or the transmission power adjustment amount decreases as the adjustment coefficient decreases. In other words, if the transmission power adjustment amount is expressed as a function of the adjustment coefficient, the derivative of the transmission power adjustment amount with respect to the adjustment coefficient is greater than 0.
第r个PUSCH的调整系数和所述第r个PUSCH中可用于传输UCI的资源数目负相关。即，可用于传输目标UCI的资源越多，该PUSCH所对应调整系数越小，Δ越小；可用于传输目标UCI的资源越少，该PUSCH所对应调整系数越大，Δ越大。具体地说，第r个PUSCH的调整系数和所述第r个PUSCH中可用于传输UCI的资源数目成反比。The adjustment coefficient of the rth PUSCH is negatively correlated with the number of resources available for UCI transmission in the rth PUSCH. That is, the more resources available for transmitting the target UCI, the smaller the adjustment coefficient corresponding to the PUSCH and the smaller Δ; the less resources available for transmitting the target UCI, the larger the adjustment coefficient corresponding to the PUSCH and the larger the Δ. Specifically, the adjustment coefficient of the rth PUSCH is inversely proportional to the number of resources available for UCI transmission in the rth PUSCH.
第r个PUSCH调整系数，具体可以是，但不限于以下(1)至(4)任意一种：The rth PUSCH adjustment coefficient may specifically be, but not limited to, any of the following (1) to (4):
(1)所述调整系数是用作参考的PUSCH的传输资源中用于UCI传输的调制符号数量Q′和第r个PUSCH的传输资源中用于UCI传输的调制符号数量Qr′的比值，即：(1) The adjustment coefficient is the ratio between the number of modulation symbols Q' used for UCI transmission in the transmission resource of the PUSCH used as a reference and the number of modulation symbols Qr ' used for UCI transmission in the transmission resource of the rth PUSCH, which is:
设参考PUSCH是M个PUSCH中的第L个，L＝1，或者L的值是预设的。或者，参考PUSCH的传输资源由所述调度信息中的资源分配字段确定。例如调度信息中的资源分配字段指示PUSCH的时间符号的个数是
(2)所述调整系数是调度信息中资源分配字段指示的时间符号个数和第r个PUSCH的传输资源中用于UCI传输的时域符号个数的比值。(2) The adjustment coefficient is the ratio of the number of time symbols indicated by the resource allocation field in the scheduling information to the number of time-domain symbols used for UCI transmission in the transmission resource of the rth PUSCH.
第r个PUSCH调整系数为The rth PUSCH adjustment coefficient is
(3)所述调整系数是所述第r个PUSCH中传输UCI的编码速率R′。(3) The adjustment coefficient is the coding rate R' of the UCI transmitted in the rth PUSCH.
所述第r个PUSCH中传输UCI的编码速率由所述UCI的信息比特数目和所述第r个PUSCH可承载的编码后信息比特数目确定，所述第r个PUSCH可承载的编码后信息比特数目由于所述第r个PUSCH包括的资源数目确定。The coding rate for transmitting UCI in the rth PUSCH is determined by the number of information bits of the UCI and the number of coded information bits that can be carried by the rth PUSCH, and the coded information bits that can be carried by the rth PUSCH The number is determined due to the number of resources included in the rth PUSCH.
此处，第r个PUSCH中传输UCI的编码速率和第r个PUSCH包括的资源数目成反比。Here, the coding rate for transmitting UCI in the rth PUSCH is inversely proportional to the number of resources included in the rth PUSCH.
(4)所述调整系数是第r个PUSCH中传输UCI编码速率和调度信息中资源分配字段指示的编码速率的比值。(4) The adjustment coefficient is the ratio of the encoding rate of the UCI transmitted in the rth PUSCH to the encoding rate indicated by the resource allocation field in the scheduling information.
参考PUSCH的传输资源中传输UCI编码速率，和第r个PUSCH的传输资源中传输UCI编码速率的比值。参考PUSCH是M个PUSCH中的第L个，L＝1，或者L的值是预设的。或者，参考PUSCH的传输资源由所述调度信息中的资源分配字段确定。例如调度信息中的资源分配字段指示PUSCH中传输UCI的目标编码速率是R，第r个PUSCH的传输资源中传输UCI编码速率是R′，则第r个PUSCH调整系数为：Reference is made to the ratio of the UCI coding rate transmitted in the transmission resource of the PUSCH to the UCI coding rate transmitted in the transmission resource of the rth PUSCH. The reference PUSCH is the Lth among M PUSCHs, L=1, or the value of L is preset. Alternatively, the transmission resource of the reference PUSCH is determined by the resource allocation field in the scheduling information. For example, the resource allocation field in the scheduling information indicates that the target coding rate for UCI transmission in PUSCH is R, and the coding rate for UCI transmission in the transmission resource of the rth PUSCH is R', then the adjustment coefficient for the rth PUSCH is:
在步骤21～22中，例如，所述发送功率调整量为：In steps 21-22, for example, the transmission power adjustment amount is:
其中BPRE*是改进BPRE值，所述改进BPRE值是BPRE值和调整系数的任意函数，并且，所述改进BPRE值和BPRE值正相关；如果所述调整系数和所述资源数目正相关(例如成正比)，则所述改进BPRE值和调整系数负相关；如果所述调整系数和所述资源数目负相关(例如成反比)，则所述改进BPRE值和调整系数正相关；其中
优选地，当所述发送功率调整量与所述调整系数正相关时，所述调整系数，用于BPRE加权乘积，来计算发送功率调整量。例如，取Preferably, when the transmission power adjustment amount is positively correlated with the adjustment coefficient, the adjustment coefficient is used for the BPRE weighted product to calculate the transmission power adjustment amount. For example, take
也就是说，这里改进BPRE值是BPRE值和调整系数的乘积：That is, the improved BPRE value here is the product of the BPRE value and the adjustment factor:
BPRE*＝ρ·BPRE (9)BPRE*=ρ·BPRE (9)
步骤30、调整并发送所述第r个PUSCH的发送功率。Step 30: Adjust and transmit the transmit power of the rth PUSCH.
根据上述10、20所述，终端设备可确定第r个PUSCH的发送功率调整量，并确定第r个PUSCH的发送功率。根据M个PUSCH各自的发送功率调整量和各自的其他发送功率决定因素，终端设备可确定所述M个PUSCH各自的发送功率。According to the above 10 and 20, the terminal device may determine the transmission power adjustment amount of the rth PUSCH, and determine the transmission power of the rth PUSCH. According to the respective transmit power adjustment amounts of the M PUSCHs and other respective transmit power determining factors, the terminal device may determine the respective transmit powers of the M PUSCHs.
需要说明的是，终端设备的发送功率P由多个因素决定，发送功率调整量为其中的一个因素。除此之外，终端设备发送PUSCH的功率P还和路径损耗、路径补偿因子、下行控制信息里发送的功率调整控制命令字、开环发送功率控制的运行点等因素相关。It should be noted that the transmission power P of the terminal device is determined by multiple factors, and the adjustment amount of the transmission power is one of the factors. In addition, the power P of the PUSCH sent by the terminal device is also related to factors such as path loss, path compensation factor, power adjustment control command word sent in downlink control information, and operating point of open-loop transmission power control.
