另外，为了更好的说明本公开，在下文的具体实施方式中给出了众多的具体细节。本领域技术人员应当理解，没有某些具体细节，本公开同样可以实施。在一些实例中，对于本领域技术人员熟知的方法、手段、元件和电路未作详细描述，以便于凸显本公开的主旨。
在通信领域中，确定数据信道的路损参考信号(PL RS，Path Loss Reference Signal)，具有十分重要的意义。对于处于连接态的终端设备，如UE等，可以通过下行控制信息(DCI，Downlink Control Information)来调度与该终端设备相关的物理上行链路共享信道(PUSCH，Physical Uplink Shared Channel)，随着DCI格式的不同，确定该PUSCH的路损参考信号也会灵活发生变化。
在相关技术中，在DCI的格式为DCI 0_0的情况下，PUSCH的路损参考信号可以根据与PUSCH相关的传输配置指示(TCI，Transmission Configuration Indicator)状态所包括的QCL-TypeD参考信号来灵活确定；在DCI的格式为DCI 0_1的情况下，PUSCH的路损参考信号可以根据DCI中包括的信道探测参考信号资源指示(SRI，SRS Resource Indicator)字段的取值来灵活确定。
相关技术中，与PUSCH相关的TCI状态所包括的QCL-TypeD参考信号目前为下行参考信号，然而随着通信技术的发展，该TCI状态所包括的QCL-TypeD参考信号可能既可以为下行参考信号，也可以为上行参考信号或信道，当这一QCL-TypeD参考信号为上行参考信号或信道的情况下，它无法作为PUSCH的路损参考信号，即通过目前的方式无法确定PUSCH的路损参考信号。同样地，随着通信技术的发展，DCI中包括的SRI字段可能会被其他字段所取代，当其被取代后，通过目前的方式，也无法确定PUSCH的路损参考信号。
为了解决上述问题，本实施例公开了一种路损参考信号的确定方法的应用示例，在本公开应用示例中，为了减小由于通信技术发展导致的目前路损参考信号确定方式不适用的问题，在一个示例中，可以在DCI的格式为DCI 0_0的情况下，在与PUSCH相关的TCI状态所包括的QCL-TypeD参考信号为上行参考信号的情况下，将PUSCH的功率控制参数中包括的某些目标参数所对应的路损参考信号，如sri-PUSCH-PowerControlId＝0所关联的SRI-PUSCH-PowerControl中所包含的PUSCH-PathlossReferenceRS-Id对应的路损参考信号或是PUSCH-PathlossReferenceRS-Id＝0所对应的路损参考信号，来作为PUSCH的路损参考信号。在一个示例中，还可以在DCI的格式为DCI 0_1的情况下，根据DCI中TCI字段的取值，来灵活的确定PUSCH的路损参考信号，比如可以根据DCI中TCI字段的取值，与PUSCH的功率控制参数建立关联，再根据关联的功率控制参数中的某些目标参数所对应的路损参考信号，如PUSCH-PathlossReferenceRS-Id所对应的路损参考信号，来作为PUSCH的路损参考信号。
通过上述过程，可以在PUSCH相关的参考信号类型发生变化导致当前的路损参考信号确定方式无法应用的情况下，或是当前用于确定路损参考信号的参数被替代的情况下，依旧确保路损参考信号可以被正常确定。
图1示出根据本公开一实施例的码本确定方法的流程图，该方法可以应用于用户设备(UE,User Equipment)，其中，UE可以为手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(MID，mobile Internetdevice)、可穿戴设备、虚拟现实(VR，virtual reality)设备、增强现实(AR，augmentedreality)设备、工业控制中的无线终端、无人驾驶中的无线终端、远程手术中的无线终端、智能电网中的无线终端、运输安全(中的无线终端、智慧城市中的无线终端、智慧家庭中的无线终端、车联网中的无线终端等等，在本实施例中不做具体限定。如图所示，在一种可能的实现方式中，该方法可以包括：
步骤S11，获取用于调度数据信道的下行控制信息DCI。
步骤S12，根据DCI的格式，结合与数据信道相关的参考信号类型或数据信道的TCI状态参数，确定数据信道的路损参考信号。
在一种可能的实现方式中，DCI所调度的数据信道可以为PUSCH。通过获取用于调度数据信道的DCI，并根据DCI的格式，结合与数据信道相关的参考信号类型或数据信道的TCI状态参数，来确定数据信道的路损参考信号，根据本公开的各方面实施例的路损参考信号的确定方法及装置，能够在数据信道相关的参考信号类型发生变化导致当前的路损参考信号确定方式无法应用的情况下，或是当前用于确定路损参考信号的参数被替代的情况下，依旧确保路损参考信号可以被正常确定。
上述各公开实施例已经提出，随着DCI格式的不同，确定数据信道的路损参考信号的方式可能会发生变化，因此，在一种可能的实现方式中，步骤S12可以包括：
步骤S121，在DCI的格式包括DCI 0_0的情况下，根据与数据信道相关的参考信号类型，确定数 据信道的路损参考信号。或者，
步骤S122，在DCI的格式包括DCI 0_1的情况下，根据数据信道的TCI状态参数，确定数据信道的路损参考信号。
通过上述各公开实施例可以看出，目前的路损参考信号确定方法，在DCI的格式为DCI 0_0，且与数据信道相关的参考信号类型为非下行参考信号的情况下，难以将该参考信号直接作为数据信道的路损参考信号；在DCI的格式为DCI 0_1的情况下，当DCI包括的SRI字段被取代时，难以确定数据信道的路损参考信号。因此，本公开实施例提出的方法，可以在DCI的格式为DCI 0_0时，根据与数据信道相关的参考信号类型的变化，灵活变换路损参考信号的确定方式；在DCI的格式为DCI 0_1时，根据数据信道的TCI状态参数来确定路损参考信号，从而尽可能的保障路损参考信号确定过程的正常实现。
需说明的是,本文所述DCI 0_0和DCI0_1是在一种可能的实现方式中用于调度PUSCH的相应参数，当调度PUSCH的参数名称发生变化时，也可以根据实际情况进行灵活选择，对应修改上述公开实施例中确定数据信道的路损参考信号的判断条件，不局限于下述各公开实施例。
具体地，在DCI的格式为DCI 0_0的情况下，如何根据与数据信道相关的参考信号类型来确定路损参考信号，其实现方式可以根据实际情况灵活决定，在一种可能的实现方式中，步骤S121可以包括：
步骤S1211，确定数据信道的相关BWP的PUCCH资源的配置状态，其中，相关BWP包括数据信道所属小区、所属载波或所属载波组的活跃BWP。
步骤S1212，在相关BWP未配置PUCCH资源的情况下，根据与数据信道相关的第一参考信号的类型，确定数据信道的路损参考信号，其中，第一参考信号包括第一CORESET对应的TCI状态包括的QCL-TypeD参考信号，第一CORESET包括，在相关BWP未配置PUCCH资源的情况下，配置在相关BWP上的最小ID的CORESET或配置在相关BWP上且与最近时隙监控的搜索空间关联的最小ID的CORESET。或者，
步骤S1213，在相关BWP配置PUCCH资源，且PUCCH资源未配置空间信息或QCL-TypeD参考信号的情况下，根据PUCCH资源，确定数据信道的路损参考信号。或者，
步骤S1214，在相关BWP配置PUCCH资源，且至少一个PUCCH资源配置空间信息或QCL-TypeD参考信号的情况下，根据PUCCH资源包括的空间信息对应的参考信号或者QCL-TypeD参考信号的类型，确定数据信道的路损参考信号。
其中，数据信道的相关部分工作带宽(BWP，Bandwidth part)，可以为数据信道所在小区的活跃BWP，或是数据信道所在载波的活跃BWP，亦或是数据信道所在载波组的活跃BWP，由于相关BWP上可能被配置有物理上行链路控制信道(PUCCH，Physical Uplink Control Channel)资源，也可能未被配置PUCCH资源，因此，随着相关BWP上PUCCH资源配置情况的不同，可以分别根据步骤S1212、S1213和S1214来灵活的确定路损参考信号，从而使得无论相关BWP上的资源被怎样配置，都尽可能的保障路损参考信号确定过程的正常实现。
具体地，通过步骤S1212可以看出，在相关BWP未被配置PUCCH资源的情况下，可以根据第一参考信号的类型，来灵活确定路损参考信号。其中，由于相关BWP上未配置PUCCH资源，第一参考信号无法从PUCCH资源中获取，因此，在一种可能的实现方式中，可以在相关BWP未被配置PUCCH资源的情况下，将相关BWP上配置的资源控制集(CORESET，Control resource set)中，选定其中ID最小的CORESET作为第一CORESET，将与此第一CORESET对应的TCI状态所包括的QCL-TypeD参考信号，来作为第一参考信号。
在一种可能的实现方式中，也可以在相关BWP未被配置PUCCH资源的情况下，从相关BWP上配置的CORESET中，选定与最近时隙(latest slot)监控的搜索空间所关联的CORESET内ID最小的CORESET(the CORESET associated with a monitored search space with the lowest CORESET-ID in the latest slot in which one or more CORESETs within the active BWP of the serving cell(s)are monitored by the UE)来作为第一CORESET，将与此第一CORESET对应的TCI状态所包括的QCL-TypeD参考信号，来作为第一参考信号。
其中，在一种可能的实现方式中，最近时隙可以是距离当前数据信道的接收时隙最近且监控的搜 索空间与CORESET关联的时隙，举例来说，接收当前数据信道PUSCH的时隙可以记为N，则在时隙N及时隙N之前，如果N-1时隙监控的搜索空间与CORESET关联，则N-1时隙可以看做为最近时隙，如果N-1时隙无需监控的PDCCH，则判断N-2时隙监控的搜索空间是否关联CORESET，依次类推，从而可以确定最近时隙。
举例来说，在一个示例中，相关BWP上可以配置有三个CORESET，这三个CORESET的ID分别为3、4和5，其中ID为4的CORESET与最近时隙监控的搜索空间所关联，则根据上述公开实施例，可以将其中ID最小的CORESET，即ID为3的CORESET作为第一CORESET，也可以将ID为4的CORESET作为第一CORESET，在将ID为3的CORESET作为第一CORESET时，第一参考信号为ID为3的CORESET对应的TCI状态包括的QCL-TypeD参考信号，而在将ID为4的CORESET作为第一CORESET时，第一参考信号则为ID为4的CORESET对应的TCI状态包括的QCL-TypeD参考信号。
随着该第一参考信号的类型不同，确定路损参考信号的方式也会发生变化。在一种可能的实现方式中，步骤S1212可以包括：
步骤S12121，在相关BWP未配置PUCCH资源的情况下，判断第一参考信号的类型是否为下行参考信号或信道，得到第一判断结果。
步骤S12122，在第一判断结果为是的情况下，将第一参考信号作为数据信道的路损参考信号。
步骤S12123，在第一判断结果为否的情况下，将第二参考信号作为数据信道的路损参考信号，其中，第二参考信号包括数据信道的功率控制参数包括的第一目标参数对应的路损参考信号。
通过上述公开实施例可以看出，在一种可能的实现方式中，在第一参考信号为下行参考信号或是信道的情况下，可以直接将第一参考信号作为数据信道的路损参考信号，在一个示例中，此时的路损参考信号可以为周期性参考信号。
而在第一参考信号不是下行参考信号或信道的情况下，比如第一参考信号为上行参考信号的情况下，如果将路损参考信号确定为第一参考信号，将会不符合通信要求，因此，此时可以根据数据信道的功率控制参数，来选定第二参考信号作为路损参考信号。在一种可能的实现方式中，第二参考信号可以是数据信道的功率控制参数中包括的第一目标参数所对应的路损参考信号，第一目标参数具体是何种参数，可以根据实际情况进行灵活决定，在一种可能的实现方式中，该第一目标参数可以是功率控制参数sri-PUSCH-PowerControlId＝0所关联的SRI-PUSCH-PowerControl中所包含的PUSCH-PathlossReferenceRS-Id这一参数，在一种可能的实现方式中，该第一目标参数也可以是PUSCH-PathlossReferenceRS-Id＝0这一参数，根据实际情况灵活选择即可。
在一种可能的实现方式中，在第一判断结果为否的情况下，即第一参考信号不是下行参考信号或信道的情况下，除了可以将第二参考信号作为数据信道的路损参考信号以外，还可以进一步根据与数据信道相关的第四参考信号的类型，来确定数据信道的路损参考信号。其中，第四参考信号是与数据信道相关的一种参考信号，其具体的实现方式可以参考后续公开实施例，在此先不做展开。
在一种可能的实现方式中，在第一判断结果为否的情况下，根据第四参考信号的类型，确定数据信道的路损参考信号的过程可以为：
在第四参考信号的类型包括下行参考信号或信道的情况下，将第四参考信号作为数据信道的路损参考信号；或者，
在第四参考信号的类型包括上行参考信号或信道的情况下，将第二参考信号，作为数据信道的路损参考信号。
通过上述过程，可以在第一参考信号无法直接作为路损参考信号的情况下，从数据信道的功率控制参数中灵活获取路损参考信号，或是从与数据信道相关的参考信号中灵活获取路损参考信号，确保路损参考信号确定过程的正常实现。
同理，通过步骤S1213可以看出，在相关BWP被配置PUCCH资源的情况下，但没有任何一个PUCCH资源配置空间信息或QCL-TypeD参考信号的情况下，由于PUCCH资源中未配置空间信息(Spatial Information or spatial setting)或是QCL-TypeD参考信号，因此无法从PUCCH资源中直接获取 空间信息对应的参考信号或者QCL-TypeD参考信号来作为路损参考信号，因此此时可以根据PUCCH资源来灵活确定数据信道的路损参考信号。
具体地，如何根据PUCCH资源来确定数据信道的路损参考信号，其实现过程也可以根据PUCCH资源中相关的路损参考信号的类型来灵活决定，在一种可能的实现方式中，步骤S1213可以包括：
步骤S12131，在相关BWP配置PUCCH资源，且PUCCH资源未配置空间信息或QCL-TypeD参考信号的情况下，判断相关BWP上是否配置CORESET，得到第二判断结果。
步骤S12132，在第二判断结果为是的情况下，根据与第三参考信号的类型或与数据信道相关的第四参考信号的类型，确定数据信道的路损参考信号，其中，第三参考信号包括第二CORESET对应的TCI状态包括的QCL-TypeD参考信号，第二CORESET包括，在相关BWP配置PUCCH资源的情况下，配置在相关BWP上的最小ID的CORESET或配置在相关BWP上且与最近时隙监控的搜索空间关联的最小ID的CORESET，第四参考信号包括数据信道相关的最小ID的活跃TCI状态包括的QCL-TypeD参考信号。
步骤S12133，在第二判断结果为否的情况下，根据与数据信道相关的第四参考信号的类型，确定数据信道的路损参考信号。
通过上述公开实施例可以看出，在相关BWP配置PUCCH资源且每个PUCCH资源均未配置空间信息或QCL-TypeD参考信号的情况下，可以首先确定相关BWP上是否配置有CORESET，继而根据相关BWP上CORESET配置情况的不同，灵活选择对应的方式来确定数据信道的路损参考信号。
其中，第二CORESET和第一CORESET中的“第二”与“第一”，仅用于区分在不同PUCCH资源的配置状态下，相关BWP配置的最小ID的CORESET或是与最近时隙监控的搜索空间关联的最小ID的CORESET，而非对两种CORESET的实现方式进行限定，即第一CORESET和第二CORESET具体的配置情况可以相同，也可以不同，在本公开实施例中不做限制。
在相关BWP上配置有CORESET的情况下，可以根据第三参考信号或是第四参考信号来确定数据信道的路损参考信号，其中，第三参考信号的确定过程可以为：从相关BWP上配置的CORESET中，选定的ID最小的CORESET或是与最近时隙监控的搜索空间关联的ID最小的CORESET，将与这第二CORESET对应的TCI状态所包括的QCL-TypeD参考信号，来作为第三参考信号。而第四参考信号的确定过程则可以为：从与数据信道相关的活跃TCI状态中，选定ID最小的活跃TCI状态，将这一选定的活跃TCI状态所包括的QCL-TypeD参考信号，来作为第四参考信号。
具体地，如何根据第三参考信号或第四参考信号的状态，来在相关BWP上配置有CORESET的情况下，确定数据信道的路损参考信号，其过程可以根据实际情况灵活确定，在一种可能的实现方式中，步骤S12132可以包括：
步骤S121321，在第二判断结果为是的情况下，判断第三参考信号的类型是否为下行参考信号或信道，得到第三判断结果。
步骤S121322，在第三判断结果为是的情况下，将第三参考信号作为数据信道的路损参考信号。
步骤S121323，在第三判断结果为否的情况下，将第二参考信号作为数据信道的路损参考信号。或者，
步骤S121324，在第三判断结果为否的情况下，根据第四参考信号的类型确定数据信道的路损参考信号。
通过上述公开实施例可以看出，在第二判断结果为是的情况下，可以先根据第三参考信号的类型来确定数据信道的路损参考信号，即若第三参考信号为下行参考信号或者信道，可以直接将第三参考信号作为数据信道的路损参考信号，而若第三参考信号为非下行参考信号或者信道，如为上行参考信号的情况下，则在一种可能的实现方式中，可以将上述公开实施例中提出的第二参考信号作为数据信道的路损参考信号；在一种可能的实现方式中，也可以不采用第二参考信号作为路损参考信号，而是根据第四参考信号的类型来确定数据信道的路损参考信号。
具体如何在第三判断结果为否的情况下，根据第四参考信号的类型，确定数据信道的路损参考信号，其实现方式可以根据实际情况灵活决定，在一种可能的实现方式中，步骤S121324可以包括：
步骤S1213241，在第三判断结果为否的情况下，确定第四参考信号的类型。
步骤S1213242，在第四参考信号的类型包括下行参考信号或信道的情况下，将第四参考信号作为数据信道的路损参考信号。
步骤S1213243，在第四参考信号的类型包括上行参考信号或信道的情况下，将第二参考信号，作为数据信道的路损参考信号。
通过上述公开实施例可以看出，在相关BWP配置有PUCCH资源，每个PUCCH资源均未配置空间信息或QCL-TypeD参考信号，但是相关BWP上配置有CORESET的情况下，根据第三参考信号或第四参考信号的类型确定数据信道路损参考信号的过程可以为：
在第三参考信号为下行参考信号或信道的情况下，将第三参考信号作为数据信道的路损参考信号，在一个示例中，此时的路损参考信号可以为周期性参考信号；或者，
在第三参考信号为非下行参考信号或信道的情况下，将第二参考信号作为数据信道的路损参考信号；或者，
在第三参考信号为非下行参考信号或信道，且第四参考信号为下行参考信号或信道的情况下，将第四参考信号作为数据信道的路损参考信号，在一个示例中，此时的路损参考信号可以为周期性参考信号；或者，
在第三参考信号为非下行参考信号或信道，且第四参考信号为上行参考信号或者信道的情况下，将上述公开实施例中提到的第二参考信号，作为数据信道的路损参考信号。
在相关BWP配置有PUCCH资源，每个PUCCH资源均未配置空间信息或QCL-TypeD参考信号，但是相关BWP上配置有CORESET的情况下，根据第三参考信号或第四参考信号的类型，来灵活确定数据信道的路损参考信号，可以提升路损参考信号确定过程的灵活性，也可以进一步保障路损参考信号确定过程的完整实现。
通过步骤S12133则可以看出，在相关BWP上未配置有CORESET的情况下，可以根据第四参考信号的类型来灵活确定数据信道的路损参考信号。在一种可能的实现方式中，步骤S12133可以包括：
步骤S121331，在第二判断结果为否的情况下，确定第四参考信号的类型。
步骤S121332，在第四参考信号的类型包括下行参考信号或信道的情况下，将第四参考信号作为数据信道的路损参考信号。
步骤S121333，在第四参考信号的类型包括上行参考信号或信道的情况下，将第二参考信号，作为数据信道的路损参考信号。
在相关BWP配置有PUCCH资源，每个PUCCH资源均未配置空间信息或QCL-TypeD参考信号，且相关BWP上未配置CORESET的情况下，在第四参考信号为下行参考信号或信道的情况下，将第四参考信号直接作为数据信道的路损参考信号，在一个示例中，此时的路损参考信号可以为周期性参考信号；或者，在第四参考信号为上行参考信号或信道的情况下，将上述公开实施例中提到的第二参考信号，作为数据信道的路损参考信号。
同理，通过步骤S1214可以看出，在相关BWP配置有PUCCH资源的情况下，且存在至少一个PUCCH资源配置有空间信息或QCL-TypeD参考信号的情况下，可以直接根据PUCCH资源包括的空间信息对应的参考信号或QCL-TypeD参考信号的类型，来确定数据信道的路损参考信号。在一种可能的实现方式中，步骤S1214可以包括：
步骤S12141，在相关BWP配置PUCCH资源，且至少一个PUCCH资源配置空间信息或QCL-TypeD参考信号的情况下，从配置空间信息或QCL-TypeD参考信号的PUCCH资源中，选定ID最小的PUCCH资源，作为待判断PUCCH资源。
步骤S12142，判断待判断PUCCH资源包括的空间信息对应的参考信号或QCL-TypeD参考信号的 类型是否为下行参考信号或信道，得到第四判断结果。
步骤S12143，在第四判断结果为是的情况下，将待判断PUCCH资源包括的空间信息对应的参考信号或QCL-TypeD参考信号，作为数据信道的路损参考信号；
步骤S12144，在第四判断结果为否的情况下，将第二参考信号，作为数据信道的路损参考信号。
其中，由于相关BWP配置的PUCCH资源中，至少一个PUCCH资源配置空间信息或QCL-TypeD参考信号，因此，可能存在多个PUCCH资源配置了空间信息或QCL-TypeD参考信号，此时，可以从这些配置了空间信息或QCL-TypeD参考信号的多个PUCCH资源中，选定ID最小的PUCCH资源来作为待判断PUCCH资源，这样，可以直接在该待判断PUCCH资源包括的空间信息对应的参考信号或QCL-TypeD参考信号为下行参考信号或信道的情况下，将该空间信息对应的参考信号或QCL-TypeD参考信号作为数据信道的路损参考信号，否则，则将上述公开实施例中提到的第二参考信号，作为路损参考信号。
需要注意的是，上述公开实施例中提到的，在DCI的格式为DCI 0_0的情况下，随着判断条件的不同而实现的各种路损参考信号的确定方式，可以根据实际情况灵活组合，在本公开实施例中不做限制。
上述各公开实施例表明了在DCI的格式为DCI 0_0的情况下，如何根据与数据信道相关的参考信号类型，来确定数据信道的路损参考信号。通过步骤S122可以看出，在DCI的格式为DCI 0_1的情况下，可以根据数据信道的TCI状态参数来确定数据信道的路损参考信号，具体如何确定可以根据实际情况灵活决定，在一种可能的实现方式中，步骤S122可以包括：
步骤S1221，在DCI的格式包括DCI 0_1的情况下，获取DCI包括的TCI状态参数。
步骤S1222，根据TCI状态参数对应的功率控制参数或TCI状态参数对应的QCL-TypeD参考信号的类型，确定数据信道的路损参考信号。
上述公开实施例中，在获取了DCI包括的TCI状态参数后，该TCI状态参数对应的QCL-TypeD参考信号，可以是TCI状态参数所对应的TCI状态所包括的QCL-TypeD参考信号。通过在DCI的格式为DCI0_1的情况下，根据TCI状态参数对应的功率控制参数或TCI状态参数对应的QCL-TypeD参考信号的类型，来确定数据信道的路损参考信号，可以使得即使DCI中的SRI字段被取代，也可以根据DCI来完成数据信道路损参考信号的确定过程，确保路损参考信号的顺利确定。需要说明的是，上述公开实施例中提到的TCI状态参数，可以是DCI中用于指示TCI状态的相关参数或字段，具体的实现方式可以根据DCI实际包括的信息情况灵活确定，在一个示例中，该TCI状态参数可以是DCI包括的TCI字段。
由于随着TCI状态参数的取值的不同，所对应的QCL-TypeD参考信号的类型也可能不同，因此，具体如何根据TCI状态参数，来确定数据信道的路损参考信号，其实现方式可以根据实际情况灵活决定。在一种可能的实现方式中，步骤S1222可以包括：
将第五参考信号作为数据信道的路损参考信号，其中，第五参考信号包括根据TCI状态参数的数值与功率控制参数建立关联后，关联的功率控制参数对应的第二目标参数对应的路损参考信号。
通过上述公开实施例可以看出，在一种可能的实现方式中，可以直接根据TCI状态参数的取值，来确定数据信道的路损参考信号，具体来说，可以根据TCI状态参数的数值，与功率控制参数建立关联，然后根据关联的功率控制参数所对应的第二目标参数所对应的路损参考信号，来作为数据信道的路损参考信号。关联的功率控制参数和对应的第二目标参数，可以根据实际情况灵活选择，在一个示例中，根据TCI状态参数的数值所关联的功率控制参数，可以是sri-PUSCH-PowerControlId参数，而基于关联的功率控制参数所对应的第二目标参数，可以是与sri-PUSCH-PowerControlId所关联的SRI-PUSCH-PowerControl参数中包含的PUSCH-PathlossReferenceRS-Id参数，即在一个示例中，可以通过根据TCI状态参数的取值，与功率控制参数sri-PUSCH-PowerControlId建立对应关联，然后将sri-PUSCH-PowerControlId所关联的SRI-PUSCH-PowerControl中所包含的PUSCH-PathlossReferenceRS-Id参数对应的参考信号，来作为第五参考信号。
在一种可能的实现方式中，步骤S1222也可以包括：在TCI状态参数对应的QCL-TypeD参考信号类型为信道探测参考信号SRS的情况下，将第五参考信号作为数据信道的路损参考信号；或者，将第二 参考信号作为所述数据信道的路损参考信号。
通过上述公开实施例可以看出，在一种可能的实现方式中，也可以根据TCI状态参数对应的QCL-TypeD参考信号的类型来灵活决定数据信道的路损参考信号，如上所述，当TCI状态参数对应的QCL-TypeD参考信号的类型为信道探测参考信号(SRS，Sounding Reference Signal)的情况下，可以将第五参考信号作为数据信道的路损参考信号，也可以将上述公开实施例中提出的第二参考信号作为路损参考信号，具体选择哪种实现方式，可以根据实际情况灵活选择。
在一种可能的实现方式中，步骤S1222也可以包括：在TCI状态参数对应的QCL-TypeD参考信号类型为下行参考信号DL RS的情况下，将TCI状态参数对应的QCL-TypeD参考信号作为所述数据信道的路损参考信号。
通过上述公开实施例可以看出，在一种可能的实现方式中，当TCI状态参数对应的QCL-TypeD参考信号的类型为下行参考信号的情况下，可以直接将该QCL-TypeD参考信号作为数据信道的路损参考信号。
在一种可能的实现方式中，步骤S1222也可以包括：在TCI状态参数对应的QCL-TypeD参考信号类型为CORESET的情况下，判断CORESET的TCI状态包括的QCL-TypeD参考信号是否为下行参考信号，得到第五判断结果；
在第五判断结果为是的情况下，将CORESET的TCI状态包括的QCL-TypeD参考信号作为数据信道的路损参考信号；
在第五判断结果为否的情况下，将第二参考信号或所述第五参考信号作为数据信道的路损参考信号。
通过上述公开实施例可以看出，在一种可能的实现方式中，当TCI状态参数对应的QCL-TypeD参考信号的类型为CORESET的情况下，可以根据该CORESET中包含的TCI状态所包括的QCL-TypeD参考信号的类型，来灵活确定数据信道的路损参考信号。若该CORSET中包含的TCI状态所包括的QCL-TypeD参考信号为下行参考信号，则可以直接将这一下行参考信号作为数据信道的路损参考信号，否则的话，则可以将上述公开实施例中提到的第二参考信号或是第五参考信号，来作为数据信道的路损参考信号。
在一种可能的实现方式中，步骤S1222也可以包括：在TCI状态参数对应的QCL-TypeD参考信号类型为PUCCH的情况下，判断PUCCH的空间信息对应的参考信号或TCI状态包括的QCL-TypeD参考信号是否为下行参考信号，得到第六判断结果；
在第六判断结果为是的情况下，将PUCCH的空间信息对应的参考信号或TCI状态包括的QCL-TypeD参考信号作为数据信道的路损参考信号；
在第六判断结果为否的情况下，将第二参考信号或第五参考信号作为数据信道的路损参考信号。
通过上述公开实施例可以看出，在一种可能的实现方式中，当TCI状态参数对应的QCL-TypeD参考信号的类型为PUCCH的情况下，可以根据该PUCCH的空间信息所对应的参考信号，或是该PUCCH中包含的TCI状态所包括的QCL-TypeD参考信号的类型，来灵活确定数据信道的路损参考信号。若该PUCCH的空间信息所对应的参考信号或是该PUCCH中包含的TCI状态所包括的QCL-TypeD参考信号为下行参考信号，则可以直接将这一下行参考信号作为数据信道的路损参考信号，否则的话，则可以将上述公开实施例中提到的第二参考信号或是第五参考信号，来作为数据信道的路损参考信号。
通过上述各公开实施例，可以看出，在DCI的格式为DCI 0_1的情况下，根据TCI状态参数对应的QCL-TypeD参考信号的类型不同，可以灵活选用不同的确定方式，来确定数据信道的路损参考信号。
需要注意的是，上述公开实施例中提到的，在DCI的格式为DCI 0_1的情况下，随着判断条件的不同而实现的各种路损参考信号的确定方式，可以根据实际情况灵活组合，在本公开实施例中不做限制。进一步地，DCI 0_0中包含的各种路损参考信号的确定方式，与DCI 0_1中包含的各种路损参考信号的 确定方式，相互之间也可以灵活组合，在本公开实施例中不做限制。
