在一些实施例中，第二信息包括以下至少一者：第一资源集合的最大数量；一个第一资源集合中的资源的最大数量；第一资源集合中的每一资源占用的符号数；一个第一资源集合内的两个资源间的最小间隔符号数；
其中，第一资源集合为终端支持的资源集合，第一资源集合内的资源用于传输第一参考信号。
在一些实施例中，第二信息还用于指示第一资源集合中各个资源的开始符号和/或结束符号等资源相关的信息。
可以理解的是，第一参考信号用于感知。第一资源集合的最大数量，即为终端支持的用于传输第一参考信号的资源集合的最大数量。一个第一资源集合中的资源的最大数量即为终端支持的一个第一资源集合内包含的用于传输第一参考信号的资源的最大数量。
在一些实施例中，网络设备接收终端发送的第二信息。可选地，网络设备根据第二信息确定第一信息。可选地，网络设备根据第二信息确定第一参考信号对应的资源的相关信息。
在一些实施例中，下述实施例中涉及的第一资源可以是第一资源集合内的资源。
在一些实施例中，第二信息也可以被称为“能力指示信息”、“终端支持信息”等，本公开实施例对其名称不作限定。
步骤S2102，终端确定第一资源。
在一些实施例中，终端可以根据自身实现确定第一资源。示例地，终端在向网络设备发送第二信息后，终端根据自身实现确定第一资源，无需网络设备通过第一信息对第一资源进行指示。
在一些实施例中，终端也可以根据第一信息确定第一资源。
在一些实施例中，第一信息是由网络设备发送的，网络设备包括接入网设备与核心网设备中的至少一者；第一信息由接入网设备配置，第一信息通过无线资源控制RRC、媒体访问控制MAC控制元素CE和下行控制信息DCI中的至少一者配置；或者，第一信息由核心网设备配置，第一信息通过核心网与终端之间的协议配置。
在一些实施例中，网络设备为接入网设备，网络设备通过无线资源控制RRC、媒体访问控制MAC控制元素CE和下行控制信息DCI中的至少一者配置第一信息；和/或，网络设备为核心网设备，网络设备通过核心网设备与终端之间的协议配置第一信息。
在一些实施例中，核心网设备包括感知功能实体或位置管理功能实体(locationmanagementfuncition，LMF)。
在一些实施例中，网络设备配置第一资源。可选地，网络设备配置第一资源后，向网络设备发送第一信息。
在另一些实施例中，该第一信息还可以是由其他终端发送的。例如，该第一信息可以是由终端设备配置得到的，并由该终端发送至另一终端。
在一些实施例中，第一信息用于指示第一资源，第一资源为第一参考信号对应的资源，第一参考信号的用途为感知。可选地，第一参考信号可以用于终端对感知目标进行感知。可选地，感知目标可以任意物体，例如可以是车辆、房屋、山体等等。
在一些实施例中，第一指示信息指示第一参考信号或第一参考信号对应的资源的用途为感知。即，第一信息可以用于指示第一参考信号的用途为感知，也可以用于指示第一资源的用途为感知。
可以理解的是，第一资源的用途为感知可以是指终端可以基于第一资源发送感知信号以及接收反射信号。
在一些实施例中，终端可以通过发送第一参考信号，并接收经过感知目标反射后的第一参考信号，进而对感知目标进行感知。可选地，终端可以通过发送第一参考信号，并由其他设备接收经过感知目标反射后的第一参考信号，进而使得其他设备对感知目标进行感知。可选地，其他设备可以是网络设备，也可以是发送该信号的终端之外的其他终端。
可选地，第一资源用于终端发送第一参考信号，和/或，接收第一参考信号。其中，终端接收的第一参考信号可以是经过感知目标反射后的信号。
在一些实施例中，第一参考信号包括以下至少一者：探测参考信号SRS；侧行链路SL定位参考信号PRS；感知参考信号。
可选地，第一信息还可以用于指示第一参考信号为何种信号。示例地，终端可以根据第一信息的指示，基于第一资源传输该第一参考信号。
在一些实施例中，第一参考信号为感知参考信号，第一信息可以无需指示第一参考信号的用途。示例地，若终端根据第一信息确定第一参考信号为感知参考信号，则可以直接确定该第一参考信号的用途为感知。
在一些实施例中，第一参考信号为SRS或SL PRS，第一信息还用于指示第一参考信号或第一参考信号对应的资源的用途为感知。示例地，网络设备还可以对该第一参考信号的用途进行配置，终端根据第一信息确定第一参考信号对应的第一资源的同时，还可以根据第一信息确定该第一参考信号的用途为感知。
也就是说，在第一参考信号为SRS或SL PRS，终端基于第一信息确定第一资源后，可能并不知道该第一资源和/或第一参考信号的用途，此时，网络设备还可以通过第一信息对该第一资源和/或第一参考信号的用途进行指示。
在一些实施例中，第一信息还用于指示第一参考信号对应的感知模式。
在一些实施例中，感知模式包括以下至少一者：
第一感知模式，在第一感知模式下，终端发送并接收第一参考信号；
第二感知模式，在第二感知模式，终端发送第一参考信号。
可选地，终端可以根据第一信息确定第一参考信号对应的感知模式，进而确定终端是否需要接收经过感知目标反射后的第一参考信号。
在一些实施例中，网络设备可以对第一参考信号的用途进行配置后，再对第一参考信号对应的感知模式进行配置，第一信息还用于指示第一参考信号对应的感知模式，即，终端可以根据第一信息的指示，确定第一参考信号是否用于感知，并确定第一参考信号对应的感知模式。
可选地，网络设备可以直接对感知模式进行配置，无需对第一参考信号的用途再进行配置，此时，终端若确定第一信息中指示了第一参考信号对应的感知模式，则可以确定该第一参考信号的用途为感知。
在一些实施例中，第一信息也可以被称为“资源配置信息”、“模式指示信息”等，本公开实施例对其名称不作限定。
步骤S2103，终端确定感知模式。
在一些实施例中，终端可以根据第一信息确定第一参考信号(或第一资源)对应的感知模式，例如第一信息还可以用于指示第一参考信号(或第一资源)对应的感知模式。
在一些实施例中，终端也可以根据自身实现确定第一参考信号(或第一资源)对应的感知模式。
示例地，第一信息可以包括第一比特，在该第一比特的值为0时，终端可以确定第一信息所指示的第一资源(或第一参考信号)对应的感知模式为第一感知模式，在该第一比特的值为1时，终端可以确定第一信息所指示的第一资源(或第一参考信号)对应的感知模式为第二感知模式。
在一些实施例中，终端确定感知模式后，可以执行步骤S2104至步骤S2107中的一者或多者。
在一些实施例中，终端确定感知模式为第一感知模式，可以执行步骤S2104至步骤S2107，或者，步骤S2105至步骤S2107。
可选地，终端确定感知模式为第二感知模式，可以执行步骤S2104至步骤S2105或者仅执行步骤S2105，不执行步骤S2106及步骤S2107。
步骤S2104，终端确定第一参考信号对应的TCI状态/空间关系信息。
在一些实施例中，第一参考信号或第一参考信号对应的资源(即第一资源)配置有传输配置指示TCI状态/空间关系信息(state/spatial relation info)。示例地，网络设备可以通过第一信息或者其他信息对第一参考信号或第一参考信号对应的资源的TCI状态/空间关系信息进行指示，终端则可以根据网络设备的指示，确定第一参考信号或第一参考信号对应的资源对应的TCI状态/空间关系信息。
也就是说，网络设备可以针对第一参考信号对应的TCI状态/空间关系信息进行指示，也可以对第一资源对应的TCI状态/空间关系信息进行指示。即，终端可以基于TCI状态/空间关系信息对应的波束传输第一参考信号，也可以在第一资源上基于TCI状态/空间关系信息对应的波束发送感知信号以及接收反射信号。
在一些实施例中，第一参考信号或第一参考信号对应的资源未配置有TCI状态/空间关系信息，终端可以根据自身实现确定第一参考信号或第一参考信号对应的资源对应的TCI状态/空间关系信息。示例地，网络设备未对第一参考信号或第一参考信号对应的资源对应的TCI状态/空间关系信息进行指示，终端则可以根据自身实现确定第一参考信号或第一参考信号对应的资源对应的TCI状态/空间关系信息。
在一些实施例中，TCI状态/空间关系信息包括准共址(Quasi co-location，QCL)信息，其中QCL Type D是空间发送或接收参数或空间域的过滤(filter)，也可以被称为波束(beam)。即，第一参考信号或第一参考信号对应的资源对应的TCI状态/空间关系信息可以用于指示该第一参考信号对应的波束或第一参考信号对应的资源对应的波束。
在一些实施例中，网络设备可以对该第一参考信号或第一参考信号对应的资源(即第一资源)对应的波束进行配置，也可以由终端自身确定第一参考信号或第一参考信号对应的资源对应的波束。
在一些实施例中，步骤S2104是可选地。例如第一参考信号或第一参考信号对应的资源对应的TCI状态/空间关系信息(或波束)可以是协议预先约定的也可以是由高层预先配置的，或者，终端可以采用任意波束发送该第一参考信号。
步骤S2105，终端基于第一资源向感知目标发送第一参考信号。
在一些实施例中，终端可以基于第一资源以及第一波束向感知目标发送第一参考信号。可选地，第一波束可以是基于TCI状态/空间关系信息确定的。
在一些实施例中，感知目标可以对第一参考信号进行反射，进而使得该终端或其他设备接收反射后的第一参考信号并对其进行测量以对感知目标进行感知。
在一些实施例中，感知目标对第一参考信号进行反射后，该第一参考信号可能会发生信号衰减、多径效应、相位变化、频率偏移、角度变化等等。可选地，终端对第一参考信号进行测量后则可以基于第一参考信号的这些变化确定感知目标相关的信息，例如距离、速度、位置、形状等。
在一些实施例中，终端确定第一参考信号对应的感知模式为第一感知模式，则在其发送第一参考信号后，期待接收感知目标反射的第一参考信号。
在一些实施例中，终端确定第一参考信号对应的感知模式为第二感知模式，则在其发送第一参考信号后，不期待接收感知目标反射的第一参考信号。
步骤S2106，终端基于第一资源接收感知目标反射的第一参考信号。
在一些实施例中，步骤S2106是可选地，终端可以在确定第一参考信号对应的感知模式为第一感知模式的情况下接收感知目标反射的第一参考信号。
可选地，终端在接收到感知目标反射的第一参考信号后，执行步骤S2107。即，终端在接收到感知目标反射的第一参考信号后，可以对该第一参考信号进行测量得到测量值。
在一些实施例中，在第一参考信号对应的感知模式为第二感知模式的情况下，感知目标反射的第一参考信号可以由其他设备接收，例如由网络设备或其他终端接收该反射的第一参考信号。可选地，其他设备在接收到感知目标反射的第一参考信号后，可以对该第一参考信号进行测量，进而得到相应的测量值。
