背景技术
目前，在新空口(New Radio，NR)系统中，在终端进行全双工传输的情况下，若终端处于连接态(connected)，则网络侧设备可以向终端发送传输功率控制(Transmit Power Control，TPC)命令，从而终端可以根据该TPC命令，确定传输探测参考信号(Sounding Reference Signal，SRS)的发射功率，以在不影响终端进行其他下行传输的同时，保证SRS的覆盖范围。
但是，由于可能会出现终端处于非连接态(即空闲态(idle)或非激活态(inactive))的情况，此时网络侧设备可能无法向终端发送TPC命令，这样可能会导致终端传输SRS的发射功率不准确的情况，因此，可能会影响终端进行其他下行传输，或会导致SRS的覆盖范围较小，从而导致终端进行其他下行传输的可靠性降低，或导致网络侧设备无法接收到SRS，如此，导致终端的通信性能较差。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚描述，显然，所描述的实施例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所获得的所有其他实施例，都属于本申请保护的范围。
以下将对本申请实施例涉及的术语进行说明。
1、TPC命令
TPC命令可用于补偿快速衰落引起的信道变化。关于当前长期演进(Long Term Evolution，LTE)系统，物理上行控制信道(Physical Uplink Control Channel，PUCCH)功率可以通过下行分配下行控制信息(Downlink Control Information，DCI)中发信号的TPC命令来调整，而物理上行共享信道(Physical Uplink Shared Channel，PUSCH)或SRS功率可以通过上行授权DCI中发信号的TPC命令来调整。此外，对于没有相关DCI的上行传输，例如半持续调度(Semi-Persistent Scheduling，SPS)、周期性信道状态信息(Channel State Information，CSI)或SRS，可以通过使用DCI format3/3A将TPC命令发信号给特定终端组(UE group)。有两种类型的TPC命令用于更新上行发射功率；一个是累积(accumulative)TPC命令，另一个是绝对(absolute)TPC命令。累积TPC命令非常适合通过使用TPC值的相对较小的步长来微调终端的发射功率。另一方面，通过使用TPC值的相对较大的步长，绝对TPC命令可用于立即提高终端的发射功率。
2、上行SRS资源
目前，NR中支持通过SRS进行上行波束训练。然而，在初始接入阶段，由于终端不发送SRS，故没有上行波束管理。终端在进行前导码(Preamble)和消息3(Msg3)，或者消息A(MsgA)的发送时采用的上行波束取决于终端的实现方法。但是，在NR的四步随机接入(4-step RACH)中，对发送Msg3的上行波束和承载消息4(Msg4)的混合自动重传请求确认(Hybrid Automatic Repeat request-Acknowledgement，HARQ-ACK)的PUCCH的上行波束的一致性有要求，即终端需要保证发送Msg3时采用的上行波束与发送承载Msg4的HARQ-ACK的PUCCH的上行波束相同。同样的，针对二步随机接入(2-step RACH)，终端需要保证发送Msg A时采用的上行波束与发送承载MsgB的HARQ-ACK的PUCCH的上行波束相同。在无线资源控制(Radio Resource Control，RRC)连接态下，基于SRS的上行波束训练结果可以用于后续上行传输。
后续通信系统可能会在终端在空闲态(idle)/非激活态(inactive)状态下引入SRS信号用于上行波束(beam)beam管理或者上行能力(capacity)增强。比如可以引入同步信号/物理广播信道块((Synchronization Signal，SS)/(Physical Broadcast Channel，PBCH)Block，SSB)/信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)与SRS的关联使得终端可以在小区接入前就可以进行上行beam的训练，确定比如更合适的物理随机接入信道(Physical Random Acces Channel，PRACH)发送波束，提升PRACH接收可靠性。另一方面，比如引入PRACH资源/MsgA资源/MsgA PUSCH资源与多个SRS资源的关联，使得不同终端可以使用不同的关联SRS beam发送相同的PRACH preamble，提升PRACH的容量。或者比如引入多个PRACH/MsgA资源/MsgA PUSCH资源到SRS的关联，这样可以支持使用相同SRS资源的多次PRACH/MsgA资源/MsgA PUSCH资源重复，从而提高PRACH/MsgA资源/MsgA PUSCH资源传输的可靠性。
另外，目前NR系统中，UE在非激活态(inactive)状态下，可以配置SRS资源发送SRS信号用于inactive状态下的终端定位。
3、其他术语
本申请的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，本申请中的“或”表示所连接对象的至少其中之一。例如“A或B”涵盖三种方案，即，方案一：包括A且不包括B；方案二：包括B且不包括A；方案三：既包括A又包括B。字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)或其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统以外的系统，如第6代(6th Generation，6G)通信系统。

图2示出了本申请实施例提供的一种发射功率确定方法的流程示意图。如图2所示，本申请实施例提供的一种发射功率确定方法可以包括下述的步骤101。
步骤101、终端在进行全双工传输的情况下，根据第一对象确定在终端处于非连接态时传输第一SRS的发射功率。
在本申请的一些实施例中，终端可以从网络侧设备接收配置信息，该配置信息用于配置终端发送第一SRS，并根据该配置信息，确定第一SRS，从而终端可以在进行全双工传输的情况下，根据第一对象确定在终端处于非连接态时传输第一SRS的发射功率。
本申请实施例中，上述第一对象包括以下至少一项：
第一参考信号对应的资源类型；
第一参考信号对应的参考信号集合；
第一SRS对应的资源类型。
在本申请的一些实施例中，上述第一参考信号为第一SRS关联的参考信号。
需要说明的是，上述“第一SRS关联的参考信号”可以理解为：与第一SRS的空间属性信息相匹配的参考信号。
在本申请的一些实施例中，在上述配置信息中还包括第一SRS的空间属性信息，从而终端可以根据第一SRS的空间属性信息，确定第一参考信号。
在本申请的一些实施例中，上述第一参考信号可以为下行参考信号，该第一参考信号可以包括以下至少一项：同步信号/物理广播信道块(Synchronization Signal and PBCH block，SSB)、信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)、跟踪参考信号(Tracking Reference Signal，TRS)、相位跟踪参考信号(Phase-Tracking Reference Signal，PTRS)。当然，第一参考信号还可以包括其他参考信号，本申请实施例在此不作限定。
在本申请的一些实施例中，上述第一参考信号对应的资源类型可以理解为：第一参考信号所占用的时域资源和/或频域资源的资源类型。
在本申请的一些实施例中，上述第一对象包括第一参考信号对应的资源类型，该第一参考信号对应的资源类型包括以下至少一项：
第一资源类型，该第一资源类型用于表征时域格式为下行的一类时域资源；
第二资源类型，该第二资源类型用于表征时域格式为第一格式的一类时域资源。
在本申请的一些实施例中，上述时域格式还可以是时域类型。其中，该第一参考信号对应的时域格式(时域类型)可以通过全双工子带配置或全双工子带指示。例如，通过TDD-UL-DL-Configuration指示的时域格式，如下行(DownLink，DL)、上行(UpLink，UL)、灵活(Flexible)；或，通过xdd-UL-DL-Configuration指示的时域类型，如全部下行(Full DL)、全部上行(Full UL)、全双工子带(Sub-Band Full Duplex，SBFD)x；或，通过全双工子带配置指示的频域格式(Frequency Format)，如下行子带(DL Subband)、上行子带(UL Subband)、保护子带(Guard Band)、下行带宽部分(DL Band Width Part，DL BWP)、上行带宽部分(UL BWP)。
本申请实施例中，上述第一格式为进行全双工传输的时域格式，该第一格式的时域资源对应的频域资源包括上行子带和下行子带。
在本申请的一些实施例中，上述第一格式的时域资源对应的整个带宽上同时包含了上行子带和下行子带。
如此可知，终端可以在第一参考信号对应的资源类型包括的不同资源类型的情况下，即可以在第一参考信号所占用的时频域资源的资源类型不同的情况下，从不同发射功率中确定传输第一SRS的发射功率，因此，可以提高确定的第一SRS的发射功率的准确性，从而在进行全双工传输时，即在接收下行传输(例如终端从网络侧设备接收的下行传输，或终端从其他设备接收的下行传输)和按照确定的第一SRS的发射功率发送第一SRS时，可以降低因发送第一SRS而导致对该下行传输进行的干扰，进而提高下行传输的性能，且可以使得第一SRS的覆盖范围得到保证；并且地，在后续终端进行半双工传输时，即在仅按照确定的第一SRS的发射功率发送第一SRS时，可以使得第一SRS的覆盖范围得到保证。
在本申请的一些实施例中，上述第二资源类型包括以下至少一项：
第三资源类型，该第三资源类型用于表征时域格式为第一格式，且对应上行子带和对应下行子带的间隔大于或等于第一预设值的一类时域资源；
第四资源类型，该第四资源类型用于表征时域格式为第一格式，且对应上行子带和对应下行子带的间隔小于或等于第二预设值的一类时域资源。
可以理解，上述第三资源类型用于表征时域资源对应的频域资源包括上行子带和下行子带，且对应上行子带和对应下行子带的间隔大于或等于第一预设值的一类时域资源；上述第四资源类型用于表征时域资源对应的频域资源包括上行子带和下行子带，且对应上行子带和对应下行子带的间隔小于或等于第二预设值的一类时域资源
在本申请的一些实施例中，上述第一预设值和第二预设值可以相同或不同。
如此可知，由于还可以将第二资源类型划分为第三资源类型和第四资源类型，以在第一参考信号所占用的时频域资源的资源类型不同的情况下，终端可以从更多的不同发射功率中确定传输第一SRS的发射功率，因此，可以进一步提高确定的第一SRS的发射功率的准确性。
在本申请的一些实施例中，上述第一参考信号对应的参考信号集合可以理解为：第一参考信号所属的参考信号集合。
在本申请的一些实施例中，上述第一对象包括第一参考信号对应的参考信号集合，上述第一参考信号对应的参考信号集合包括以下至少一项：

第二参考信号集合，该第二参考信号集合中包括对应的时域资源的时域格式为第一格式的参考信号；
第三参考信号集合，该第三参考信号集合中包括对应的时域资源的时域格式为第一格式、且对应上行子带和对应下行子带的间隔大于或等于第三预设值的参考信号；
第四参考信号集合，该第四参考信号集合中包括对应的时域资源的时域格式为第一格式、且对应上行子带和对应下行子带的间隔小于或等于第四预设值的参考信号。
本申请实施例中，上述第一格式为进行全双工传输的时域格式，该第一格式的时域资源对应的频域资源包括上行子带和下行子带。
在本申请的一些实施例中，上述第三预设值和第四预设值可以相同或不同，上述第三预设值和第一预设值可以相同或不同。

如此可知，终端可以在第一参考信号对应的参考信号集合包括的不同参考信号集合的情况下，即可以在第一参考信号所占用的时频域资源的资源类型不同的情况下，从不同发射功率中确定传输第一SRS的发射功率，因此，可以提高确定的第一SRS的发射功率的准确性，从而在进行全双工传输时，即在接收下行传输和按照确定的第一SRS的发射功率发送第一SRS时，可以降低因发送第一SRS而导致对该下行传输进行的干扰，进而提高下行传输的性能，且可以使得第一SRS的覆盖范围得到保证；并且地，在后续终端进行半双工传输时，即在仅按照确定的第一SRS的发射功率发送第一SRS时，可以使得第一SRS的覆盖范围得到保证。
在本申请的一些实施例中，上述第一对象包括第一SRS对应的资源类型，该第一SRS对应的资源类型包括以下至少一项：
第五资源类型，该第五资源类型用于表征时域格式为下行的一类时域资源；
第六资源类型，该第六资源类型用于表征时域格式为第一格式，且对应的参考信号不包含第二参考信号的一类时域资源；
第七资源类型，该第七资源类型用于表征时域格式为第一格式，且对应的参考信号包含第二参考信号的一类时域资源；
第八资源类型，该第八资源类型用于表征时域格式为第一格式，且与第一参考信号对应的时域资源之间的间隔大于或等于第五预设值的一类时域资源。
本申请实施例中，上述第一格式为进行全双工传输的时域格式，该第一格式的时域资 源对应的频域资源包括上行子带和下行子带。
在本申请的一些实施例中，上述第二参考信号可以包括以下至少一项：公共信号、广播信号。其中，该广播信号可以包括以下至少一项：SSB、系统信息块(System Information Block，SIB)、主信息块(Master Information Block，MIB)、寻呼(Paging)信号等。
如此可知，终端可以在第一SRS对应的资源类型包括的不同资源类型的情况下，即可以在第一SRS所占用的时频域资源的资源类型不同的情况下，从不同发射功率中确定传输第一SRS的发射功率，因此，可以提高确定的第一SRS的发射功率的准确性，从而在进行全双工传输时，即在接收下行传输和按照确定的第一SRS的发射功率发送第一SRS时，可以降低因发送第一SRS而导致对该下行传输进行的干扰，进而提高下行传输的性能，且可以使得第一SRS的覆盖范围得到保证；并且地，在后续终端进行半双工传输时，即在仅按照确定的第一SRS的发射功率发送第一SRS时，可以使得第一SRS的覆盖范围得到保证。
本申请实施例提供一种发射功率确定方法，终端在进行全双工传输的情况下，可以根据第一对象确定在终端处于非连接态时传输第一SRS的发射功率，其中，该第一对象包括第一参考信号对应的资源类型、第一参考信号对应的参考信号集合以及第一SRS对应的资源类型中的至少一个。由于在终端进行全双工传输的情况下，终端可以根据第一参考信号对应的资源类型、第一参考信号对应的参考信号集合以及第一SRS对应的资源类型中的至少一个，准确地确定在终端处于非连接态时传输第一SRS的发射功率，而无需根据网络设备发送的TPC命令确定，因此，可以避免出现影响终端进行下行传输的情况，或可以避免SRS的覆盖范围较小，从而可以提高终端进行下行传输的可靠性，或使得网络侧设备可以接收到SRS，如此，可以提高终端的通信性能。
下面将举例说明终端确定传输第一SRS的发射功率的具体方案。
示例一、
在本申请的一些实施例中，上述第一对象包括以下至少一项：第一参考信号对应的资源类型、第一参考信号对应的参考信号集合。可选地，结合图2，如图3所示，上述步骤101具体可以通过下述的步骤101a和步骤101b实现。
步骤101a、终端在进行全双工传输的情况下，根据第一参考信号对应的资源类型和第一参考信号对应的参考信号集合中的至少一个，获取目标功率参数。
在本申请的一些实施例中，上述目标功率参数包括以下至少一项：
目标接收功率；
功率偏移值；
路径损耗补偿因子；
TPC命令；
功率补偿因子；
最大发射功率；
路径损耗参数。
在本申请的一些实施例中，上述功率偏移值可以为正数，或负数，或0。
在本申请的一些实施例中，上述路径损耗参数可以包括路径损耗估计值、路径损耗估计对应的参考信号等。
在本申请的一些实施例中，网络侧设备可以预先为第一参考信号对应的资源类型和/或第一参考信号对应的参考信号集合配置了对应的功率参数，从而终端可以直接将第一参考信号对应的资源类型对应的功率参数确定为目标功率参数的至少部分功率参数，和/或可以直接将第一参考信号对应的参考信号集合对应的功率参数确定为目标功率参数的至少部分 功率参数。
在本申请的一些实施例中，结合图3，如图4所示，在上述步骤101a之前，本申请实施例提供的发射功率确定方法还可以包括下述的步骤201，且上述步骤101a具体可以通过下述的步骤101a1实现。
步骤201、终端接收与第一参考信号相关的第一功率配置信息。
本申请实施例中，上述第一功率配置信息包括以下至少一项：至少一个参考信号集合对应的至少一个功率参数、至少一个资源类型对应的至少一个功率参数。
在本申请的一些实施例中，在第一功率配置信息包括至少一个参考信号集合对应的至少一个功率参数的情况下，上述第一对象包括第一参考信号对应的参考信号集合；和/或，在第一功率配置信息包括至少一个资源类型对应的至少一个功率参数的情况下，上述第一对象包括第一参考信号对应的资源类型。
在本申请的一些实施例中，上述至少一个功率参数中的每个功率参数包括以下至少一项：
目标接收功率；
功率偏移值；
路径损耗补偿因子；
TPC命令；
功率补偿因子；
最大发射功率；
路径损耗参数。
可以理解，由于目标功率参数为至少一个功率参数中的一个功率参数，因此，目标功率参数也包括目标接收功率、功率偏移值、路径损耗补偿因子、TPC命令、功率补偿因子、最大发射功率、路径损耗参数中的至少一个。
在本申请的一些实施例中，上述功率偏移值可以为正数，或负数，或0。
在本申请的一些实施例中，上述路径损耗参数可以包括路径损耗估计值、路径损耗估计对应的参考信号等。
在本申请的一些实施例中，终端可以从网络侧设备接收第一功率配置信息。
步骤101a1、终端从至少一个功率参数中，确定与第一参考信号对应的资源类型和第一参考信号对应的参考信号集合中的至少一个所对应的目标功率参数。
在本申请的一些实施例中，终端可以先从至少一个参考信号集合中，确定出与第一参考信号对应的参考信号集合相同的一个参考信号集合，然后再将该一个参考信号集合对应的功率参数，确定为目标功率参数的至少部分功率参数；和/或，终端可以先从至少一个资源类型中，确定出与第一参考信号对应的资源类型相同的一个资源类型，然后再将该一个资源类型对应的功率参数，确定为目标功率参数的至少部分功率参数。
如此可知，终端可以接收到包括至少一个参考信号集合对应的至少一个功率参数和/或至少一个资源类型对应的至少一个功率参数的第一功率配置信息，这样终端可以直接根据第一参考信号对应的资源类型和第一参考信号对应的参考信号集合中的至少一个，准确地确定出目标功率参数。
步骤101b、终端根据目标功率参数，确定在终端处于非连接态时传输第一SRS的发射功率。
在本申请的一些实施例中，在目标功率参数包括目标接收功率、路径损耗补偿因子、功率补偿因子、最大发射功率以及路径损耗参数中的至少一个的情况下，终端可以将与该 目标接收功率对应的发射功率，确定为传输第一SRS的发射功率。
在本申请的一些实施例中，在目标功率参数包括功率偏移值的情况下，终端可以采用第一算法，根据功率偏移值，计算得到传输第一SRS的发射功率。可选地，上述目标功率参数包括第一功率偏移值。上述步骤101b具体可以通过下述的步骤101b1和步骤101b2实现。
步骤101b1、终端根据基于第一功率偏移值，确定第一发射功率。
在本申请的一些实施例中，终端可以先采用上行功率控制计算得到的第三发射功率，然后再根据第三发射功率和第一功率偏移值，确定第一发射功率。
步骤101b2、终端根据第一发射功率和第二发射功率，确定在终端处于非连接态时传输第一SRS的发射功率。
本申请实施例中，上述第二发射功率为终端的最大发射功率。
在本申请的一些实施例中，上述最大发射功率可以理解为：终端所驻留的小区允许的最大发射功率。
在本申请的一些实施例中，终端可以将第一发射功率和第二发射功率中，最小的发射功率确定为在终端处于非连接态时传输第一SRS的发射功率。
可以理解，终端可以采用第一算法，根据第一功率偏移值计算得到在终端处于非连接态时传输第一SRS的发射功率。
其中，该第一算法具体可以为：
PSRS＝min{PCMAX，PUL PC,SRS+offset}；
其中，该PSRS为传输第一SRS的发射功率，该PCMAX为终端的最大发射功率(即第二发射功率)，PUL_PC,SRS为终端采用上行功率控制计算得到的第三发射功率，offset为第一功率偏移值。
需要说明的是，针对终端确定终端的最大发射功率的说明，可以参考相关技术中的具体描述，本申请实施例在此不予赘述。
在一些示例中，终端可以采用第二算法，计算得到上述第三发射功率PUL_PC,SRS。
其中，该第二算法具体可以为：
P＝min{PCMAX,[p0(j)+α(k)*PL(q)±f(l)+[10lgM+Δ]}；
其中，PCMAX为终端在该上行载波的配置传输功率(该上行载波允许的最大传输功率)，p0(j)为开环接收端功率目标值，与网络侧设备期望的目标信号噪声干扰比(Signal-to-Noise Interference Ratio，SINR)和干扰强度相关，此目标SINR的值越大，通常上行传输功率越高，接收端的SINR越高。PL(q)为路损估计，q为索引，从终端维护的一组路损估计值中选一个。对于同一个终端，同一服务小区的不同的参考信号也可能经历不同的路损，如SSB波束宽度较宽，波束赋形增益较低，路损估计大；而CSI-RS波束较窄，波束赋形增益高，路损估计较小，因此，同一终端需要维护多个路损估计值，并根据网络侧配置或者指示的索引取出某路损估计值来计算传输功率。闭环部分f(l)为第l个功率控制偏移(调节)状态值，可快速地、针对某个终端的某次传输调节其传输功率，调节依据为上一次传输的效果，调节信息通过物理层信令(例如DCI)快速调节(相关参数仍由RRC高层信令准静态配置)。此类调节被称为闭环调节，举个例子，比如网络侧设备发现终端的某次传输功率过高，网络侧设备可以在调度下一次同类型上行传输时，用DCI通知终端将传输功率降低1分贝(dB)。DCI中携带的闭环功率控制信息称为TPC，表示为δ(l)。
如此可知，由于终端可以先基于第一功率偏移值确定第一发射功率，然后再根据终端的最大发射功率和该第一发射功率，确定在终端处于非连接态时传输第一SRS的发射功率， 即确定出的传输第一SRS的发射功率是考虑到终端的最大发射功率，因此，可以避免出现确定的传输第一SRS的发射功率大于终端的最大发射功率的情况。
在本申请的一些实施例中，在目标功率参数包括TPC命令的情况下，终端可以将该TPC命令所指示的发射功率，确定为传输第一SRS的发射功率。
如此可知，由于终端可以直接根据第一参考信号对应的资源类型和第一参考信号对应的参考信号集合中的至少一个，获取到对应的目标功率参数，因此，终端可以根据该目标功率参数，准确地确定出传输第一SRS的发射功率。
举例说明，假设目标功率参数包括第一功率偏移值，第一参考信号为SSB，则终端可以先接收与SSB相关的第一功率配置信息，该第一功率配置信息中包括SSB集合1(例如上述实施例中的第一参考信号集合)对应的功率偏移值(power offset)，例如power offset 1＝X，和SSB集合2(例如上述实施例中的第二参考信号集合)对应的功率偏移值(power offset)，例如power offset 2＝Y。
从而在终端工作在全双工传输模式时，在idle/inactive态下，终端发起第一SRS的传输，可以根据与第一SRS关联的第一SSB对应的SSB集合(例如SSB集合1)，获取第一功率偏移值power offset 1(即X)，并采用第一算法，根据power offset 1计算得到传输第一SRS的发射功率；其中，该第一算法为：PSRS＝min{PCMAX，PUL PC,SRS+offset 1}，该PSRS为传输第一SRS的发射功率，该PCMAX为终端的最大发射功率(即第二发射功率)，PUL_PC,SRS为终端采用上行功率控制计算得到的第三发射功率，offset 1为上述power offset 1(即X)。或者，
在终端工作在全双工传输模式时，在idle/inactive态下，终端发起第一SRS的传输，可以根据与第一SRS关联的第一SSB对应的SSB集合(例如SSB集合2)，获取第一功率偏移值power offset 2(即Y)，并采用第一算法，根据power offset 2计算得到传输第一SRS的发射功率；其中，该第一算法为：PSRS＝min{PCMAX，PUL PC,SRS+offset 2}，该PSRS为传输第一SRS的发射功率，该PCMAX为终端的最大发射功率(即第二发射功率)，PUL_PC,SRS为终端采用上行功率控制计算得到的第三发射功率，offset 2为上述power offset 2(即Y)。
示例二、

在本申请的一些实施例中，上述目标功率参数包括以下至少一项：
目标接收功率；
功率偏移值；
路径损耗补偿因子；
传输功率控制TPC命令；
功率补偿因子；
最大发射功率；

在本申请的一些实施例中，网络侧设备可以预先为第一SRS对应的资源类型配置了对应的功率参数，从而终端可以直接将第一SRS对应的资源类型对应的功率参数确定为目标功率参数。
在本申请的一些实施例中，结合图5，如图6所示，在上述步骤101c之前，本申请实 施例提供的发射功率确定方法还可以包括下述的步骤301，且上述步骤101c具体可以通过下述的步骤101c1实现。
步骤301、终端接收与第一SRS相关的第二功率配置信息。
本申请实施例中，上述第二功率配置信息包括至少一个资源类型对应的至少一个功率参数。
在本申请的一些实施例中，上述至少一个功率参数中的每个功率参数包括以下至少一项：
目标接收功率；
功率偏移值；
路径损耗补偿因子；
TPC命令；
功率补偿因子；
最大发射功率；
路径损耗参数。
在本申请的一些实施例中，终端可以从网络侧设备接收第二功率配置信息。
步骤101c1、终端从至少一个功率参数中，确定与第一SRS对应的资源类型所对应的目标功率参数。
在本申请的一些实施例中，终端可以先从至少一个资源类型中，确定出与第一SRS对应的资源类型相同的一个资源类型，然后再将该一个资源类型对应的功率参数，确定为目标功率参数。
如此可知，终端可以接收到包括至少一个资源类型对应的至少一个功率参数的第二功率配置信息，这样终端可以直接根据第一SRS对应的资源类型，准确地确定出目标功率参数。
步骤101d、终端根据目标功率参数，确定在终端处于非连接态时传输第一SRS的发射功率。
需要说明的是，针对终端根据目标功率参数，确定在终端处于非连接态时传输第一SRS的发射功率的说明，可以参考上述实施例中的具体描述，本申请实施例在此不再赘述。
如此可知，由于终端可以直接根据第一SRS对应的资源类型，获取到对应的目标功率参数，因此，终端可以根据该目标功率参数，准确地确定出传输第一SRS的发射功率。
在本申请的一些实施例中，上述目标功率参数包括第一功率偏移值。上述步骤101d具体可以通过下述的步骤101d1和步骤101d2实现。
步骤101d1、终端根据基于第一功率偏移值，确定第一发射功率。
步骤101d2、终端根据第一发射功率和第二发射功率，确定在终端处于非连接态时传输第一SRS的发射功率。
本申请实施例中，上述第二发射功率为终端的最大发射功率。
如此可知，由于终端可以先基于第一功率偏移值确定第一发射功率，然后再根据终端的最大发射功率和该第一发射功率，确定在终端处于非连接态时传输第一SRS的发射功率，即确定出的传输第一SRS的发射功率是考虑到终端的最大发射功率，因此，可以避免出现确定的传输第一SRS的发射功率大于终端的最大发射功率的情况。
举例说明，假设目标功率参数包括功率偏移值，第一参考信号为SSB，则终端可以先接收与第一SRS相关的第二功率配置信息，该第二功率配置信息中包括类型1(例如上述实施例中的第五资源类型)对应的功率偏移值(power offset)，例如power offset 1＝0，类 型2(例如上述实施例中的第六资源类型)对应的功率偏移值(power offset)，例如power offset 2＝X，类型3(例如上述实施例中的第七资源类型)对应的功率偏移值(power offset)，例如power offset 3＝Y，类型4(例如上述实施例中的第八资源类型)对应的功率偏移值(power offset)，例如power offset 4＝Z。
从而在终端工作在全双工传输模式时，在idle/inactive态下，终端发起第一SRS的传输，可以根据第一SRS对应的资源类型(例如类型1)，获取第一功率偏移值power offset 1(即0)，并采用第一算法，根据power offset 1计算得到传输第一SRS的发射功率；其中，该第一算法为：PSRS＝min{PCMAX，PUL PC,SRS}，该PSRS为传输第一SRS的发射功率，该PCMAX为终端的最大发射功率(即第二发射功率)，PUL_PC,SRS为终端采用上行功率控制计算得到的第三发射功率，因为power offset 1为0，因此，在第一算法中未体现power offset 1。或者，在终端工作在全双工传输模式时，在idle/inactive态下，终端发起第一SRS的传输，可以根据第一SRS对应的资源类型(例如类型2)，获取第一功率偏移值power offset 2(即X)，并采用第一算法，根据power offset 2计算得到传输第一SRS的发射功率；其中，该第一算法为：PSRS＝min{PCMAX，PUL PC,SRS+offset2}，该PSRS为传输第一SRS的发射功率，该PCMAX为终端的最大发射功率(即第二发射功率)，PUL_PC,SRS为终端采用上行功率控制计算得到的第三发射功率，该offset2为上述power offset 2(即X)。或者，在终端工作在全双工传输模式时，在Idle/inactive态下，终端发起第一SRS的传输，可以根据第一SRS对应的资源类型(例如类型3)，获取power offset 3(即Y)，并采用第一算法，根据power offset 3计算得到传输第一SRS的发射功率；其中，该第一算法为：PSRS＝min{PCMAX，PUL PC,SRS+offset3}，该PSRS为传输第一SRS的发射功率，该PCMAX为终端的最大发射功率(即第二发射功率)，PUL_PC,SRS为终端采用上行功率控制计算得到的第三发射功率，该offset3为上述power offset 3(即Y)。或者，在终端工作在全双工传输模式时，在idle/inactive态下，终端发起第一SRS的传输，可以根据第一SRS对应的资源类型(例如类型4)，获取power offset 4(即Z)，并采用第一算法，根据power offset 4计算得到传输第一SRS的发射功率；其中，该第一算法为：PSRS＝min{PCMAX，PUL PC,SRS+offset4}，该PSRS为传输第一SRS的发射功率，该PCMAX为终端的最大发射功率(即第二发射功率)，PUL_PC,SRS为终端采用上行功率控制计算得到的第三发射功率，该offset4为上述power offset 4(即Z)。
示例三、
假设目标功率参数包括第一功率偏移值，第一参考信号资源为SSB，则终端可以先接收与SSB相关的第一功率配置信息和第二功率配置信息，该第一功率配置中包括SSB集合1(例如上述实施例中的第一参考信号集合)对应的功率偏移值(power offset)，例如power offset 1，和SSB集合2(例如上述实施例中的第二参考信号集合)对应的功率偏移值(power offset)，例如power offset 2，该第二功率配置信息中包括类型1(例如上述实施例中的第五资源类型)对应的功率偏移值(power offset)，例如power offset 1，类型2(例如上述实施例中的第六资源类型)对应的功率偏移值(power offset)，例如power offset 2，类型3(例如上述实施例中的第七资源类型)对应的功率偏移值(power offset)，例如power offset 3，类型4(例如上述实施例中的第八资源类型)对应的功率偏移值(power offset)，例如power offset 4。
从在终端选择在时域格式为UL的时域资源上的SRS传输机会(第七资源类型)发起第一SRS的传输时，该第一SRS所关联的第一SSB，是包含在SSB集合1，则第一SRS的发射功率根据以下公式确定：PSRS＝min{PCMAX，PUL PC,SRS+offset1}，其中，PUL_PC,SRS为上 行功率控制确定的第三发射功率，PCMAX表示终端的最大发射功率(即第二发射功率)，offset1为第一功率偏移值power offset 3。或者，
在终端选择在位于时域格式为第一格式，且不包含下行公共或广播信号的时域资源上的SRS传输机会(即第六资源类型)发起第一SRS的传输时，该第一SRS所关联的第一SSB，是包含在SSB集合1，第一SRS的发射功率根据以下公式确定：PSRS＝min{PCMAX，PUL PC,SRS+offsetX}，其中，上述公式中的“offsetX”(即第一功率偏移值)可以是基于power offest 1和power offset 4确定的一个功率偏移，例如公式中的“offsetX”＝power offest 1+power offest 4。
在终端选择在位于时域格式为第一格式，且包含下行公共或广播信号的时域资源上的SRS传输机会(即第七资源类型)发起第一SRS的传输时，该第一SRS所关联的第一SSB，是包含在SSB集合2，第一SRS的发射功率根据以下公式确定：PSRS＝min{PCMAX，PUL PC,SRS+offsetY}，其中，上述公式中的“offsetY”(即第一功率偏移值)可以是基于power offest 2和power offset 5确定的一个功率偏移，例如公式中的“offsetY”＝power offest 2+power offest 5。
