网络设备102可以是任意一种具有无线收发功能的设备。该设备包括但不限于：终端 设备、各种基站(宏站、微站、竿站或者中继器(repeater，RP)等)、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WiFi)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为5G，如，NR系统中的gNB，或，传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括有源天线单元(active antenna unit，AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能。比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、介质接入控制(medium access control，MAC)层和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备。本申请实施例对于网络设备102的具体种类或者名称也不做限定。
感知目标103可以是指终端设备需要感知的各类目标，根据不同的实际场景可以为不同的物体，本申请实施例对此不作限定。
终端设备101在向网络设备102发送通信信号时，终端设备101为通信信号的发送方，网络设备102为通信信号的接收方。即，通信信号的发送与接收是单向传播的，终端设备101在发送通信信号时，在相关技术中需要计算终端设备101至网络设备102之间单向传播的路径损耗，并根据该路径损耗以及其他参数确定通信信号的发送功率。
以5G新空口(New Radio，NR)系统中终端设备发送上行探测参考信号(sounding reference signal，SRS)为例，其发送功率的确定方式如下：
其中，PCMAX为最大允许发送功率，PO_SRS为初始功率分量，MSRS为SRS信号的带宽，αSRS为路损补偿因子，PL为路径损耗(pathloss)，h为动态功率调整因子。PCMAX、PO_SRS、MSRS和αSRS均由网络设备发送的高层配置信息确定。PL由终端设备测量路径损耗参考信号(pathloss reference signal，PL-RS)获得，h由网络设备发送的物理控制信息确定，该物理控制信息可以为各种上下行物理控制信息。并且，
PL＝referenceSignalPower-higher layer filtered(RSRP)       (2)
其中，referenceSignalPower为PL-RS的发送功率，higher layer filtered(RSRP)为高层滤波后的PL-RS接收功率值(Reference Signal Receiving Power，RSRP)。PL-RS可以是网络设备发送的下行参考信号，其发送功率保持不变，并且由网络设备发送的高层配置信息确定。
此外，5G NR系统中终端设备基于物理侧行共享信道(physical sidelink shared channel，PSSCH)发送侧行信号时，需要考虑侧行信号对网络设备接收上行信号的干扰问题。因此，侧行信号的发送功率不大于当前时刻终端设备的上行发送功率。其中，与上述公式(1)类似的，该上行发送功率为终端设备根据下行参考信号的最大允许发送功率、初始功率分量、下行参考信号的带宽、路损补偿因子、路径损耗、动态功率调整因子等参数来确定。
当终端设备101在向感知目标103发送感知信号时，感知信号的传播路径是由终端设备101发送至感知目标103，之后感知目标103再将感知信号反射至终端设备101，终端设备101再接收该感知信号。即，终端设备101进行单站感知时，感知信号是双向传播的，终端设备101既是感知信号的发送方，也是感知信号的接收方。这样，终端设备101在对感知信号的发送功率进行控制时，需要考虑终端设备101与感知目标103之间双向传播的路径损耗，以及感知目标103的反射损耗。
相关技术中，终端设备能够实现对通信信号的功率控制，但无法实现对感知信号的功率控制，无法实现感知信号的正常发送。
在本申请实施例中，终端设备接收配置信息；该配置信息包括第一感知信号的带宽、第一感知信号对应的最大允许发送功率以及初始功率分量；在目标时刻，按照第一感知信号在目标时刻的发送功率发送第一感知信号，该第一感知信号在目标时刻的发送功率根据配置信息确定。这样，终端设备基于配置信息确定出在目标时刻针对第一感知信号的发送功率，实现了对感知信号发送功率的控制，保证了感知信号的正常发送。
下面，通过具体实施例对本申请所示的方案进行详细说明。需要说明的是，下面几个 实施例可以独立存在，也可以相互结合，对于相同或相似的内容，在不同的实施例中不再重复说明。
下面，结合图2所示的实施例，对功率控制的过程进行说明。
图2为本申请实施例提供的一种功率控制方法的流程示意图。请参见图2，该方法可以包括：
S201、网络设备发送配置信息。相应的，终端设备接收配置信息。其中，配置信息包括第一感知信号的带宽、第一感知信号的最大允许发送功率以及第一感知信号的初始功率分量。
本申请实施例中，第一感知信号可以是指终端设备当前配置的需要发送的感知信号。第一感知信号的带宽可以是指感知信号的信号带宽，可以用Msensing表示。第一感知信号对应的最大允许发送功率可以是指终端设备发送第一感知信号时允许达到的最大功率，可以用PCMAX表示。第一感知信号对应的初始功率分量可以是指终端设备发送第一感知信号时对应的初始功率，可以用PO-sensing表示。
具体的，配置信息中可以包括第一感知信号的带宽、第一感知信号的最大允许发送功率以及第一感知信号的初始功率分量中的一个或者多个，各个参数的具体数值可以是由高层配置的，也可以通过其他方式确定，本申请实施例对此不作限定。第一感知信号对应的最大允许发送功率和初始功率分量在一段时间内可以是固定的，当需要对该配置信息进行更新时，网络设备可以向终端设备重新发送配置信息，实现对第一感知信号对应的最大允许发送功率和初始功率分量的重新配置。
需要说明的是，本申请实施例中的功率控制方法，发送配置信息的执行主体，可以是指网络设备，也可以是指网络设备中的芯片或者芯片模组；类似的，终端设备侧的执行主体，可以是指终端设备，也可以是指终端设备中的芯片或者芯片模组，本申请实施例对此不作限定。
S202、在目标时刻，终端设备按照第一感知信号在目标时刻的发送功率发送第一感知信号，第一感知信号在目标时刻的发送功率根据配置信息确定。
本申请实施例中，目标时刻可以是指终端设备发送第一感知信号的时刻，该目标时刻可以用i表示。终端设备在配置第一感知信号时，可以根据感知信号的初始位置以及发送周期，确定出发送第一感知信号的各个目标时刻。相应的，第一感知信号在目标时刻的发送功率可以用Psensing(i)表示。终端设备在接收到配置信息之后，可以根据配置信息，计算出在目标时刻发送第一感知信号的发送功率Psensing(i)。这样，在目标时刻i，终端设备可以按照该Psensing(i)发送第一感知信号，实现了对第一感知信号的功率控制，保证了第 一感知信号的正常发送。
本申请实施例提供的功率控制方法，终端设备接收配置信息；该配置信息包括第一感知信号的带宽、第一感知信号对应的最大允许发送功率以及初始功率分量；在目标时刻，按照第一感知信号在目标时刻的发送功率发送第一感知信号，该第一感知信号在目标时刻的发送功率根据配置信息确定。这样，终端设备基于配置信息确定出在目标时刻针对第一感知信号的发送功率，实现了对感知信号发送功率的控制，保证了感知信号的正常发送。
在上述任意一个实施例的基础上，下面，结合图3所示的实施例，对功率控制的过程进行详细说明。
图3为本申请实施例提供的又一种功率控制方法的流程示意图。请参见图3，该方法可以包括：
S301、网络设备发送配置信息。相应的，终端设备接收配置信息。配置信息包括第一感知信号的带宽、第一感知信号对应的最大允许发送功率以及第一感知信号对应初始功率分量；该配置信息用于确定第一感知信号在目标时刻的发送功率。
S302、终端设备根据PL-RS的相关数据，确定第一感知信号的补偿功率；PL-RS包括于配置信息中。
本申请实施例中，在感知信号传输的过程，由于存在双向路径损耗以及感知目标的反射损耗，因此，终端设备在确定发送功率时，需要将这部分功率进行补偿，即终端设备需要确定补偿功率，该补偿功率可以用ΔP表示。网络设备发送的配置信息中，还可以包括有PL-RS，该PL-RS用于指示终端设备按照哪个信号的相关数据来计算补偿功率。这样，终端设备基于配置信息中的PL-RS，并可以根据PL-RS的相关数据，计算出第一感知信号的补偿功率ΔP。
在一种可能的实施方式中，PL-RS为第一感知信号，或者，PL-RS为除第一感知信号之外的其他感知信号。
本申请实施例中，终端设备功率控制的对象为感知信号，PL-RS的类型可以为感知信号，以保证功率计算的准确度。该PL-RS可以为终端设备当前配置的第一感知信号，也可以为除第一感知信号以外的其他感知信号，例如第二感知信号。当路径损耗参考信号PL-RS为第二感知信号时，终端设备可以将第二感知信号的路径损耗近似看作第一感知信号的路径损耗，并可以基于第二感知信号的相关数据来计算第一感知信号的补偿功率。这样，通过对路径损耗参考信号PL-RS的配置，提高了感知信号功率控制的灵活性，确保了感知信号功率控制的正常实现，一定程度上提高了感知精度。
S303、终端设备根据配置信息以及补偿功率，确定第一感知信号在目标时刻的发送功 率。
S304、在目标时刻，终端设备按照发送功率发送第一感知信号。
可选的，S303中，第一感知信号的补偿功率可以通过以下方式一至方式三中的任意一种方式实现。
方式一、PL-RS的相关数据包括路损补偿因子和PL-RS的平均路径损耗；第一感知信号的补偿功率为路损补偿因子与PL-RS的平均路径损耗的乘积；其中，平均路径损耗基于PL-RS的历史发送功率以及PL-RS的历史接收功率确定。
本申请实施例中，历史发送功率可以是终端设备在历史时间发送PL-RS的功率，可以用Psensing表示。该历史时间可以基于实际需求灵活设置，例如，历史发送功率可以为终端设备前10次发送PL-RS的功率。需要强调的是，在通信信号的功率控制过程中(即此时PL-RS的类型为通信信号)，PL-RS的发送功率是不变的，可以由高层配置信息确定，而本申请实施例中PL-RS的类型为感知信号，其历史发送功率是动态变化的，终端设备也能够直接获取该PL-RS的历史发送功率。历史接收功率可以是终端设备在历史时间接收PL-RS的功率，可以用RSRP表示。
终端设备将同一次感知中PL-RS的历史发送功率减去历史接收功率，即可得到该次感知中的路径损耗。平均路径损耗可以是指多次感知的路径损耗的平均值。该平均路径损耗也可以是指路径损耗的高层滤波值，可以用higher layer filtered(Psensing-RSRP)表示。
路损补偿因子可以是指路径损耗的缩放因子，用于在一定程度上避免路径损耗测量不准确的情况。可以用αsensing表示。在确定出平均路径损耗之后，终端设备可以用路损补偿因子对平均路径损耗进行缩放，得到补偿功率ΔP。以下公式(3)示出了本申请实施例中补偿功率ΔP的一种计算方式：
ΔP＝αsensing*higher layer filtered(Psensing-RSRP)        (3)
本申请实施例中，根据路径损耗参考信号PL-RS的历史发送功率和历史接收功率确定平均路径损耗，并通过路损补偿因子对平均路径损耗进行缩放，得到补偿功率，提高了补偿功率确定的合理性和准确性。
可选的，该路损补偿因子包括在配置信息中。此时，S304也可以描述为：根据配置信息以及平均路径损耗，确定第一感知信号在目标时刻的发送功率。其中，平均路径损耗和配置信息中的路损补偿因子用于确定补偿功率，配置信息中的其他信息用于和补偿功率一起确定第一感知信号在目标时刻的发送功率。
本申请实施例中，网络设备向终端设备发送的配置信息中可以包括有路损补偿因子。终端设备可以基于平均路径损耗和配置信息中的路损补偿因子来确定补偿功率，之后再基 于补偿功率和配置信息中的其他信息(第一感知信号的带宽、第一感知信号对应的最大允许发送功率以及第一感知信号对应的初始功率分量)来确定第一感知信号在目标时刻的发送功率。
方式二、PL-RS的相关数据包括功率平均值和PL-RS的期望接收功率，功率平均值为PL-RS的历史接收功率平均值；第一感知信号的补偿功率为PL-RS的期望接收功率与功率平均值之间的差值。
本申请实施例中，期望接收功率可以是指PL-RS的预期接收功率，可以用expected RSRP表示。需要说明的是，当PL-RS为第一感知信号时，该期望接收功率可以为第一感知信号对应的期望接收功率；当PL-RS为除第一感知信号以外的其他感知信号(例如第二感知信号)时，该期望接收功率可以为其他感知信号(例如第二感知信号)对应的期望接收功率。
历史接收功率平均值可以是指PL-RS的多个历史接收功率的均值，例如，可以是指PL-RS历史接收功率的高层滤波值，可以用higher layer filtered(RSRP)来表示。以下公式(4)示出了本申请实施例中补偿功率ΔP的另一种计算方式：
ΔP＝expected RSRP-higher layer filtered(RSRP)       (4)
本申请实施例中，将PL-RS的期望接收功率与历史接收功率平均值的差值作为补偿功率，能够降低补偿功率计算的复杂度，提高补偿功率计算的灵活性。
可选的，该期望接收功率包括在配置信息中，由高层配置。此时，S304也可以描述为：根据配置信息以及PL-RS的历史接收功率平均值，确定第一感知信号在目标时刻的发送功率。其中，PL-RS的历史接收功率平均值和配置信息中的期望接收功率用于确定补偿功率，配置信息中的其他信息用于和补偿功率一起确定第一感知信号在目标时刻的发送功率。
本申请实施例中，网络设备向终端设备发送的配置信息中可以包括有期望接收功率。终端设备可以基于PL-RS的历史接收功率平均值和配置信息中的期望接收功率来确定补偿功率，之后再基于补偿功率和配置信息中的其他信息(第一感知信号的带宽、第一感知信号对应的最大允许发送功率以及第一感知信号对应的初始功率分量)来确定第一感知信号在目标时刻的发送功率。
方式三、PL-RS的相关数据包括PL-RS的前一次接收功率和PL-RS的期望接收功率；第一感知信号的补偿功率为PL-RS的期望接收功率与PL-RS的前一次接收功率之间的差值。
本申请实施例中，前一次接收功率可以是指终端设备在发送PL-RS时前次感知时接收到该PL-RS时的历史接收功率。以当前时刻为i为例，前一次接收功率可以表示为RSRP (i-1)。终端设备可以将PL-RS的期望接收功率与前一次接收该PL-RS的历史接收功率相减，得到补偿功率。以下公式(5)示出了本申请实施例中补偿功率ΔP的另一种计算方式：
ΔP＝expected RSRP-RSRP(i-1)          (5)
本申请实施例中，将PL-RS的期望接收功率与PL-RS的前一次接收功率之间的差值，确定为补偿功率。这样，终端设备在发送第一感知信号时，根据前一次的测量数据即可实现发送功率的调整，无需进行多次测量取平均值，无需进行高层滤波，提高了发送功率调整的速度。
可选的，该期望接收功率包括在配置信息中，由高层配置。此时，S304也可以描述为：根据配置信息以及PL-RS的前一次接收功率，确定第一感知信号在目标时刻的发送功率。其中，PL-RS的前一次接收功率和配置信息中的期望接收功率用于确定补偿功率，配置信息中的其他信息用于和补偿功率一起确定第一感知信号在目标时刻的发送功率。
本申请实施例中，网络设备向终端设备发送的配置信息中可以包括有期望接收功率。终端设备可以基于PL-RS的前一次接收功率和配置信息中的期望接收功率来确定补偿功率，之后再基于补偿功率和配置信息中的其他信息(第一感知信号的带宽、第一感知信号对应的最大允许发送功率以及第一感知信号对应的初始功率分量)来确定第一感知信号在目标时刻的发送功率。
需要说明的是，在具体实现时，可以只存在方式一、方式二、方式三中的任意一种方式，此时，通过存在的方式确定补偿功率即可，也可以存在方式一、方式二、方式三中的多种方式，在多种方式中选择或者配置一种方式确定补偿功率，本申请不作限制。
在一种可能的实施方式中，S304在具体实现时，可以通过如下方式实现：
第一感知信号在目标时刻的发送功率为备选发送功率与最大允许发送功率之间的较小值；备选发送功率根据初始功率分量、第一感知信号的补偿功率和带宽因子经过线性相乘或对数相加得到，带宽因子基于第一感知信号的带宽确定。
本申请实施例中，带宽因子可以是指基于第一感知信号带宽确定的功率调整因子。通常信号发送功率是按照1个资源块(Resource Block，RB)计算的，但是信号的带宽可能为有多个RB，例如10个RB等，因而终端设备需要基于第一感知信号带宽，确定出带宽因子，保证第一感知信号发送功率确定的准确性。该带宽因子可以用10log10Msensing表示。
以下公式(6)示出了本申请实施例中发送功率一种计算方式：
其中，初始功率分量PO-sensing、补偿功率ΔP与带宽因子10log10Msensing三部分的计算，可以是在对数域内的相加，即三部分都为对数形式，然后进行对数相加，得到备选发送功率；也可以为线性相乘，即将上述三部分计算为具体实数值，然后三个实数值相乘，得到备选发送功率。终端设备之后再确定备选发送功率与最大允许发送功率PCMAX的大小关系，将二者中的较小值确定为第一感知信号在目标时刻的发送功率。
需要说明的是，补偿功率ΔP、带宽因子或者发送功率Psensing(i)的计算方式也可以为其他形式，并不局限于上述公式(3)至公式(6)，可以基于实际需求进行灵活设置，本申请实施例对此不作限定。
在一种可能的实施方式中，第一感知信号的发送功率小于或者等于终端设备确定的在目标时刻的上行发送功率。
本申请实施例中，上行发送功率可以是指终端设备在目标时刻基于物理上行共享信道(Physical Uplink Shared Channel，PUSCH)发送上行信息时的功率。由于终端设备基于PUSCH发送的上行信息为通信信号，终端设备可以将目标时刻上行信息的上行发送功率，称为假想上行发送功率，当然也可以采用其他名称，本申请对此不作限定。该上行发送功率可以是终端设备提前确定的，也可以是包括在配置信息中，由高层提前配置的，本申请对此亦不作限制。
本申请实施例中，在目标时刻，终端设备发送第一感知信号的发送功率不超过终端设备在目标时刻的上行发送功率，这样能够避免第一感知信号发送功率过大造成的对通信环境干扰较大的情况，降低感知信号对终端设备与网络设备之间信号收发的干扰。
在一种可能的实施方式中，第一感知信号的发送功率小于或者等于终端设备确定的在目标时刻的侧行发送功率。
本申请实施例中，侧行发送功率可以是指终端设备在目标时刻基于物理侧行共享信道(Physical Sidelink Share Channel，PSSCH)发送侧行信息时的功率。同样的，由于终端设备基于PSSCH发送的侧行信息为通信信号，终端设备可以将目标时刻侧行信息的侧行发送功率，称为假想侧行发送功率。当然也可以采用其他名称，本申请对此不作限定。该侧行发送功率可以是终端设备提前确定的，也可以是包括在配置信息中，由高层提前配置的，本申请对此亦不作限制。
本申请实施例中，在目标时刻，终端设备发送第一感知信号的发送功率不超过侧行发送功率，这样能够降低环境干扰，避免对终端设备之间侧行信号的收发产生干扰。
在图3所示的实施例中，网络设备发送配置信息；终端设备接收配置信息；该配置信息包括第一感知信号的带宽、第一感知信号对应的最大允许发送功率、初始功率分量；终 端设备根据PL-RS的相关数据，确定第一感知信号的补偿功率；该PL-RS包括于配置信息中；终端设备根据配置信息以及补偿功率，确定第一感知信号在目标时刻的发送功率；在目标时刻，终端设备按照发送功率发送第一感知信号。这样，终端设备基于PL-RS的相关数据，计算出补偿功率，再基于配置信息和补偿功率确定出终端设备在目标时刻针对第一感知信号的发送功率，实现了感知信号发送功率的控制，能够保证第一感知信号功率计算的准确度，在保证感知精度的同时，降低了环境干扰。
