具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
图1是根据本公开的实施例示出的一种处理能力请求方法的示意流程图。本实施例所述的方法可以适用于第一终端，所述第一终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等电子设备。以下实施例中的第二终端，可以是后续处理能力发送方法所适用的第二终端。
所述第一终端可以进行基于感知的服务，基于感知的服务包括但不限于测量与其他终端的距离、测量与其他终端的角度、测量与其他终端的距离和角度、测量与其他终端的相对位置等。
但是进行基于感知的服务，需要其他设备参与，所以第一终端需要先发现附近其他也能够进行基于感知的服务的设备。基于以下实施例，第一终端可以发现附近其他也能够进行基于感知的服务的设备，例如第二终端。在基于感知的服务中，第一终端可以称作发现(Discovery)设备，也可以称作广播(Announcing)设备，第二终端可以称作被发现(Discoveree)设备，也可以称作监听(Monitoring/Listening)设备。
如图1所示，所述处理能力请求方法可以包括以下步骤：
在步骤S101中，广播第一消息，其中，所述第一消息中携带有请求信息，所述请求信息用于请求接收到所述请求信息的第二终端的处理能力信息。
在一个实施例中，由于第一终端并不知道附近存在哪些终端，也不知道附近哪些终端支持基于感知的服务的设备，所以可以通过广播的方式发送第一消息，以确保附近的终端都能够接收到第一消息。
在第一消息中可以携带有请求信息，请求信息用于请求接收到所述请求信息的第二终端的处理能力信息，其中，所述第二终端并非特指某个终端，是指第一终端附近接收到请求信息的终端。
第二终端在接收到第一消息后，若第二终端支持基于感知的服务，基于所述请求可以向第一终端发送第二消息，在第二消息中携带所述第二终端的处理能力信息。进而第一终端在接收到第二终端的处理能力信息后，可以根据处理能力信息确定第二终端到第一终端的距离，或者在后续的感知过程中确定第二终端到第一终端的距离。
需要说明的是，根据处理能力信息确定第二终端到第一终端的距离，只是第一终端根据处理能力信息所进行的基于感知的业务的一种示例，还可以根据处理能力信息确定其他信息，例如确定与第二终端的相对位置等，本实施例以及其他实施例，主要基于确定距离的示例进行描述。
在一个实施例中，所述处理能力信息包括以下至少之一：
单位时间内处理数据的数据量、响应预设信息所需的时间(可以称作应答时间，reply time，或者接收发送时间，Rx-Tx timing)。
在处理能力信息为单位时间内处理数据的数据量时，第一终端根据单位时间内处理数据的数据量，可以计算出第二终端响应预设信息所需的时间，进而根据响应预设信息所需的时间确定接收第二终端响应信息的目标时刻，以便与第二终端进行后续通信，还可以进一步确定第二终端到第一终端的距离。
其中，所述预设信息可以是第一终端向第二终端发送的感知请求消息(ranging request)和/或感知参考信号(ranging signal)，第二终端针对预设信息向第一终端发送的响应信息可以是确认(ACK)信息。
例如第一终端在确定第二终端响应预设信息所需的时间T0后，第一终端可以确定向第二终端发送所述预设信息的第一时刻T1，以及接收到所述第二终端针对所述预设信息向所述第一终端发送响应信息的第二时刻T2，那么第二时刻与第一时刻的差值(T2-T1)就是预设信息从第一终端发送至第二终端，经由第二终端响应，进而第一终端接收到响应信息的总时长。总时长减去第二终端响应预设信息所需的时间(T2-T1-T0)，就是预设信息从第一终端发送至第二终端，以及响应信息从第二终端发送至第一终端的时长。
预设信息和响应信息的传播速度都为光速c，那么(T2-T1-T0)/c，就是第一终端到第二终端距离，加上第二终端到第一终端的距离，也即两倍的第一终端到第二终端距离2d，据此，可以计算出第一终端到第二终端的距离d＝(T2-T1-T0)c/2。
根据本公开的实施例，第一终端通过在广播的第一消息中携带请求信息，不仅可以确定附近哪些终端能够进行基于感知的服务，还能够使得支持基于感知的服务的第二终端向第一终端发送第二终端的处理能力信息，从而第一终端根据处理能力信息能够确定后续的感知方法以及确定第二终端响应感知信息所需要的时间，有利于第一终端与第二终端后续感知过程，进一步确定第二终端到第一终端的距离，以便与第二终端进行基于感知的服务。
在一个实施例中，第一终端可以通过目标应用发起基于感知的服务，在目标应用发起基于感知的服务时，可以触发第一终端广播第一消息，而所述请求信息可以表征为目标应用的标识，也可以表征为第一消息中的信息元素，还可以表征为目标应用 的标识和信息元素。第二终端在接收到第一消息后，可以基于目标应用的标识和/或所述信息元素确定第一终端需要进行基于感知的服务。
可选地，所述预设信息包括预设业务的请求信息或预设业务的参考信号，所述响应预设信息所需的时间包括：
所述第二终端从接收到其他终端发送的所述预设信息，到向所述其他终端发送所述预设信息的反馈信息的时长。
在一个实施例中，其他终端包括但不限于第一终端，预设信息包括但不限于感知请求消息和/或感知参考信号。
在响应预设信息所需的时间为第二终端从接收到其他终端发送的预设信息，到向其他终端发送预设信息的反馈信息的时长的情况下，第一终端可以直接确定第二终端在接收到第一终端发送的预设信息后，响应预设信息所需的时间T0，从而可以根据可以确定向第二终端发送所述预设信息的第一时刻T1，以及接收到所述第二终端针对所述预设信息向所述第一终端发送响应信息的第二时刻T2，计算出第一终端到第二终端的距离d，例如如上述实施例所述，d＝(T2-T1-T0)c/2。
可选地，所述预设信息为同步信号，所述响应预设信息所需的时间包括：
所述第二终端接收到其他终端发送的同步信号的时刻相对所述第二终端的同步定时栅格的偏差值，以及所述第二终端向其他终端发送同步信号的时刻相对所述第二终端的同步定时栅格的偏差值。
在一个实施例中，其他终端包括但不限于第一终端，预设信息包括但不限于同步信号。
在响应预设信息所需的时间为所述第二终端接收到第一终端发送的同步信号的时刻相对所述第二终端的同步定时栅格的偏差值，以及第二终端向第一终端发送同步信号的时刻相对所述第二终端的同步定时栅格的偏差值的情况下，第一终端为了确定第一终端到第二终端的距离，还需要确定第一终端向第二终端发送同步信号的时刻相对于第一终端的同步定时栅格的偏差值，以及第一终端接收到第二终端发送的同步信号的时刻相对于第一终端的同步定时栅格的偏差值。
例如第一终端向第二终端发送同步信号的时刻相对于第一终端的同步定时栅格(slot n,symbol l)的偏差值为t1，第二终端接收到第一终端发送的同步信号的时刻相对所述第二终端的同步定时栅格(slot n,symbol l)的偏差值为t2，第二终端向第一终端 发送同步信号的时刻相对所述第二终端的同步定时栅格(slot m,symbol k)的偏差值为t3，第一终端接收到第二终端发送的同步信号的时刻相对于第一终端的同步定时栅格(slot m,symbol k)的偏差值为t4，其中m和n可以理解为时隙号，l和k可以理解为时隙中的第几个符号。
那么同步信号从第一终端发送至第二终端，第二终端接收同步信号后向第一终端发送响应信息，所述响应信息可以为同步信号，进而第一终端接收到第二终端发送的响应信息的总时长就等于RD_time＝(m-n)*T_slot+(k-l)*T_sym+(t1+t4)，第二终端从接收到第一终端发送的同步信号，到向第一终端发送同步信号的时长为Reply_time＝(m-n)*T_slot+(k-l)*T_sym-(t2+t3)，其中，T_slot标识时隙slot的时长，T_sym标识符号symbol的时长。
那么同步信号在第一终端和第二终端往返传输的时长就等于RD_time-Reply_time＝t1+t2+t3+t4，那么第一终端到第二终端的距离d＝(t1+t2+t3+t4)c/2。
图2是根据本公开的实施例示出的另一种处理能力请求方法的示意流程图。如图2所示，所述方法还包括：
在步骤S102中，接收所述第二终端发送的第二消息，其中，所述第二消息包含所述第二终端的处理能力信息。
在一个实施例中，第二终端在接收到第一终端发送的第一消息后，若第二终端能够进行基于感知的服务，可以针对第一消息中的请求信息向第一终端发送处理能力信息，而处理能力信息可以携带在第二消息中发送给第一终端。第二消息除了携带处理能力信息，还可以携带其他信息，例如第二终端的标识等。
需要说明的是，当第一终端附近没有第二终端，或者虽然第一终端附近有第二终端，但是第二终端不能进行基于感知的服务，那么步骤S102可以不执行。
可选地，所述处理能力信息包括以下至少一个：
标识，用于指示所述第二终端具备将响应预设信息所需的时间确定为固定值的能力；
数值，用于指示所述第二终端响应预设信息所需的时间。
在一个实施例中，处理能力信息可以包括标识，可以包括数值，还可以既包括标识，又包括数值。
其中，所述数值用于指示所述第二终端响应预设信息所需的时间，所述标识用于指示所述第二终端具备将响应预设信息所需的时间确定为固定值的能力，也即在处理能力信息中包含所述标识的情况下，第二终端每次响应预设信息所需的时间是固定值，那么第一终端只需接收到一次第二终端发送的所述第二终端响应预设信息所需的时间即可，后续都可以按照该固定值来接收第二终端针对第一终端发送的预设信息的响应。
而在所述处理能力信息中不包括所述标识，仅包括数值的情况下，表示第二终端不具备固定应答时间的能力，所述数值虽然仍能表示所述第二终端响应预设信息所需的时间，但是所表示的时间相对粗略，第一终端并不能将该数值直接应用于后续感知过程，只能初步确定第二终端针对第一终端发送的预设信息的响应所需要的时间。
例如在处理能力信息中只有数值，没有标识，第一终端可以确定所述数值表示第二终端发送的针对第一终端发送的预设信息的确认信息的时间间隔，例如第二终端收到第一终端发送的感知参考信号ranging signal,然后向第一终端发送确认消息所需要的时间，该时间不是精确的应答时间；例如处理能力信息中既有数据，又有标识，第一终端可以确定所述数值表示第二终端响应来自所述第一终端的预设信息所需的时间。
图3是根据本公开的实施例示出的又一种处理能力请求方法的示意流程图。如图3所示，所述方法还包括：
在步骤S103中，响应于所述处理能力信息包括所述标识和所述数值，确定所述第二终端具备将响应预设信息所需的时间确定为固定值的能力，且所述固定值为所述数值；
在步骤S104中，根据所述数值确定接收所述第二终端发送的针对所述第一终端发送的预设信息的确认信息的目标时刻。
在一个实施例中，在处理能力信息包括标识和数值的情况下，第一终端可以确定所述第二终端具备将响应预设信息所需的时间确定为固定值的能力，且所述固定值为所述数值，并且处理能力信息中的数值表征所述第二终端响应来自所述第一终端的预设信息所需的时间，那么在后续感知过程中，第一终端可以根据所述数值确定接收所述第二终端发送的针对所述第一终端发送的预设信息的确认信息的目标时刻，进而可以在目标时刻接收所述第二终端发送的确认信息，并且在感知过程中可以直接利用 所述数值，不需要第二终端再次向第一终端发送响应预设信息所需要的时间。
由于第二终端具备将响应预设信息所需的时间确定为固定值的能力，所以第二终端响应预设信息所需的时间是固定的，那么第二终端只需向第一终端发送一次所述数值来表示所述固定值即可，后续可以不必再向第一终端发送第二终端响应预设信息所需的时间。
需要说明的是，在本实施例以及其他实施例中，第二终端发送的针对所述第一终端发送的预设信息的确认信息，可以是针对第一终端发送的感知请求消息和/或感知参考信号的确认信息。
图4是根据本公开的实施例示出的又一种处理能力请求方法的示意流程图。如图4所示，所述处理能力信息包括数值，所述方法还包括：
在步骤S105中，响应于所述处理能力信息包括所述数值且不包括所述标识，确定所述第二终端不具备将响应预设信息所需的时间确定为固定值的能力；
在步骤S106中，根据所述数值确定接收所述第二终端发送的针对所述第一终端发送的预设信息的确认信息的时间间隔。
在一个实施例中，在处理能力信息包括数值而不包括标识的情况下，第一终端可以确定第二终端不具备将响应预设信息所需的时间确定为固定值的能力，以及确定处理能力信息中的数值所表示的所述第二终端响应预设信息所需的时间相对粗略，那么第一终端根据所述数值并不能准确地确定上述实施例中的目标时刻，但是可以确定第二终端发送的针对所述第一终端发送的预设信息的确认信息的时间间隔，例如时间间隔大于或等于所述数值对应的时间，从而可以根据所述时间间隔接收所述第二终端发送的确认信息，以免过于频繁地尝试接收第二终端发送的确认信息而造成电量浪费。并且在后续感知过程中，第二终端还还需要向第一终端发送准备且的响应预设信息所需要的时间。
进一步地，为了使得第一终端能够确定具体的目标时刻，第二终端在发送确认信息时，将所述第二终端响应来自所述第一终端的预设信息所需的时间发送给第一终端。但是由于第二终端不具备将响应预设信息所需的时间确定为固定值的能力，所以第二终端响应预设信息所需的时间不是固定的，那么第二终端每次从第一终端接收到预设信息后，都需要重新确定第二终端响应预设信息所需的时间，进而将所确定的第二终端响应预设信息所需的时间发送至所述第一终端。
图5是根据本公开的实施例示出的又一种处理能力请求方法的示意流程图。如图5所示，所述处理能力信息包括标识，所述方法还包括：
在步骤S107中，响应于所述处理能力信息包括所述标识且不包括所述数值，确定所述第二终端具备将响应预设信息所需的时间确定为固定值的能力。
在一个实施例中，所述处理能力信息还可以只包括标识，在这种情况下，可以终端可以确定所述第二终端具备将响应预设信息所需的时间确定为固定值的能力，但是可能因为某些原因，例如通信资源不足，导致未能将标识和数值一同发给第一终端，但是后续会将数值发送给第一终端，那么第一终端根据标识可以在后续与第二终端通信过程中，从第二终端接收第二终端响应预设信息所需的时间。
图6是根据本公开的实施例示出的一种处理能力发送方法的示意流程图。本实施例所述的方法可以适用于第二终端，所述第二终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等电子设备。以下实施例中的第一终端，可以是上述处理能力请求方法所适用的第一终端。
如图6所示，所述处理能力发送方法可以包括以下步骤：
在步骤S201中，接收第一终端广播的第一消息，其中，所述第一消息中携带有请求信息，所述请求信息用于请求接收到所述请求信息的第二终端的处理能力信息；
在步骤S202中，向所述第一终端发送所述处理能力信息。
在一个实施例中，第一终端可以通过广播的方式发送第一消息，第二终端在接收到第一消息后，若第二终端支持基于感知的服务，可以向第一终端发送第二消息，在第二消息中携带所述第二终端的处理能力信息。进而第一终端在接收到第二终端的处理能力信息后，可以根据处理能力信息确定第二终端到第一终端的距离。
根据本公开的实施例，第二终端根据第一消息中的请求信息向第一终端发送处理能力信息，使得第一终端不仅可以确定第二终端能够进行基于感知的服务，还能够根据处理能力信息确定接收第二终端响应信息的目标时刻，以便第一终端与第二终端进行后续通信，还可以进一步确定第二终端到第一终端的距离，以便与第二终端进行基于感知的服务。
可选地，所述处理能力信息包括以下至少之一：
单位时间内处理数据的数据量、响应预设信息所需的时间
可选地，所述预设信息包括预设业务的请求信息或预设业务的参考信号，所述响应预设信息所需的时间包括：
所述第二终端从接收到其他终端发送的所述预设信息，到向所述其他终端发送所述预设信息的反馈信息的时长。
在一个实施例中，其他终端包括但不限于第一终端，预设信息包括但不限于感知请求消息和/或感知参考信号。
在响应预设信息所需的时间为第二终端从接收到其他终端发送的预设信息，到向其他终端发送预设信息的反馈信息的时长的情况下，第一终端可以直接确定第二终端在接收到第一终端发送的预设信息后，响应预设信息所需的时间T0，从而可以根据可以确定向第二终端发送所述预设信息的第一时刻T1，以及接收到所述第二终端针对所述预设信息向所述第一终端发送响应信息的第二时刻T2，计算出第一终端到第二终端的距离d，例如如上述实施例所述，d＝(T2-T1-T0)c/2。
可选地，所述预设信息为同步信号，所述响应预设信息所需的时间包括：
所述第二终端接收到其他终端发送的同步信号的时刻相对所述第二终端的同步定时栅格的偏差值，以及所述第二终端向其他终端发送同步信号的时刻相对所述第二终端的同步定时栅格的偏差值。
在一个实施例中，其他终端包括但不限于第一终端，预设信息包括但不限于同步信号。
在响应预设信息所需的时间为所述第二终端接收到第一终端发送的同步信号的时刻相对所述第二终端的同步定时栅格的偏差值，以及第二终端向第一终端发送同步信号的时刻相对所述第二终端的同步定时栅格的偏差值的情况下，第一终端为了确定第一终端到第二终端的距离，还需要确定第一终端向第二终端发送同步信号的时刻相对于第一终端的同步定时栅格的偏差值，以及第一终端接收到第二终端发送的同步信号的时刻相对于第一终端的同步定时栅格的偏差值。
例如第一终端向第二终端发送同步信号的时刻相对于第一终端的同步定时栅格(slot n,symbol l)的偏差值为t1，第二终端接收到第一终端发送的同步信号的时刻相对所述第二终端的同步定时栅格(slot n,symbol l)的偏差值为t2，第二终端向第一终端发送同步信号的时刻相对所述第二终端的同步定时栅格(slot m,symbol k)的偏差值为t3，第一终端接收到第二终端发送的同步信号的时刻相对于第一终端的同步定时栅格 (slot m,symbol k)的偏差值为t4，其中m和n可以理解为时隙号，l和k可以理解为时隙中的第几个符号。
那么同步信号从第一终端发送至第二终端，第二终端接收同步信号后向第一终端发送响应信息，所述响应信息可以为同步信号，进而第一终端接收到第二终端发送的响应信息的总时长就等于RD_time＝(m-n)*T_slot+(k-l)*T_sym+(t1+t4)，第二终端从接收到第一终端发送的同步信号，到向第一终端发送同步信号的时长为Reply_time＝(m-n)*T_slot+(k-l)*T_sym-(t2+t3)，其中，T_slot标识时隙slot的时长，T_sym标识符号symbol的时长。
那么同步信号在第一终端和第二终端往返传输的时长就等于RD_time-Reply_time＝t1+t2+t3+t4，那么第一终端到第二终端的距离d＝(t1+t2+t3+t4)c/2。
可选地，所述处理能力信息包括以下至少一个：
标识，用于指示所述第二终端具备将响应预设信息所需的时间确定为固定值的能力；
数值，用于指示所述第二终端响应预设信息所需的时间。
在一个实施例中，处理能力信息可以包括标识，可以包括数值，还可以既包括标识，又包括数值。
其中，所述数值用于指示所述第二终端响应预设信息所需的时间，所述标识用于指示所述第二终端具备将响应预设信息所需的时间确定为固定值的能力，也即在处理能力信息中包含所述标识的情况下，第二终端每次响应预设信息所需的时间是固定值，那么第一终端只需接收到一次第二终端发送的所述第二终端响应预设信息所需的时间即可，后续都可以按照该固定值来接收第二终端针对第一终端发送的预设信息的响应。
而在所述处理能力信息中不包括所述标识，仅包括数值的情况下，表示第二终端不具备固定应答时间的能力，所述数值虽然仍能表示所述第二终端响应预设信息所需的时间，但是所表示的时间相对粗略，第一终端并不能将该数值直接应用于后续感知过程，只能初步确定第二终端针对第一终端发送的预设信息的响应所需要的时间。
例如在处理能力信息中只有数值，没有标识，第一终端可以确定所述数值表示第二终端发送的针对第一终端发送的预设信息的确认信息的时间间隔，例如第二终端收到第一终端发送的感知参考信号ranging signal,然后向第一终端发送确认消息所需 要的时间，该时间不是精确的应答时间；例如处理能力信息中既有数据，又有标识，第一终端可以确定所述数值表示第二终端响应来自所述第一终端的预设信息所需的时间。
图7是根据本公开的实施例示出的一种处理能力请求方法的示意流程图。本实施例所述的方法可以适用于第三终端，所述第三终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等电子设备。以下实施例中的第四终端，可以是后续处理能力发送方法所适用的第四终端。
所述第三终端可以进行基于感知的服务，基于感知的服务包括但不限于测量与其他终端的距离、测量与其他终端的角度、测量与其他终端的距离和角度、测量与其他终端的相对位置等。
但是进行基于感知的服务，需要其他设备参与，所以第三终端需要先发现附近其他也能够进行基于感知的服务的设备。基于以下实施例，第三终端可以通过广播自身的处理能力信息，使得附近其他能够进行基于感知的服务的设备(例如第四终端)发现第三终端。在基于感知的服务中，第三终端可以称作被发现设备，第四终端可以称作发现设备。
如图7所示，所述处理能力发送方法可以包括以下步骤：
在步骤S301中，广播第三消息，其中，所述第三消息中携带所述第三终端的处理能力信息。
在一个实施例中，由于第三终端并不知道附近存在哪些终端，也不知道附近哪些终端支持基于感知的服务的设备，所以可以通过广播的方式发送第三消息，以确保附近的终端都能够接收到第三消息。
在第三消息中可以携带有第三终端的处理能力信息，当第四终端在接收到第三消息后，若第四终端支持基于感知的服务，可以根据第三消息中第三终端的处理能力信息，确定第三终端响应感知信息所需要的时间，以便第四终端与第三终端进行后续感知过程，进一步确定第三终端到第四终端的距离，以便与第三终端进行基于感知的服务。
在一个实施例中，第三终端可以通过目标应用发起基于感知的服务，在目标应用发起基于感知的服务时，可以触发第三终端广播第三消息，而所述第三消息中的处理能力信息可以表征为目标应用的标识，也可以表征为第三消息中的信息元素，还可 以表征为目标应用的标识和信息元素。第四终端在接收到第三消息后，可以基于目标应用的标识和/或所述信息元素确定第三终端需要进行基于感知的服务。
需要说明的是，第三终端与前述实施例中的第四终端可以是相同的终端，其中第四终端是以终端作为发现设备的角度进行描述，第三终端是以终端作为被发现终端的角度进行描述。
可选地，所述处理能力信息包括以下至少之一：
单位时间内处理数据的数据量、响应预设信息所需的时间
可选地，所述预设信息包括预设业务的请求信息或预设业务的参考信号，所述响应预设信息所需的时间包括：
所述第三终端从接收到其他终端发送的所述预设信息，到向所述其他终端发送所述预设信息的反馈信息的时长。
在一个实施例中，其他终端包括但不限于第四终端，预设信息包括但不限于感知请求消息和/或感知参考信号。
在响应预设信息所需的时间为第三终端从接收到其他终端发送的预设信息，到向其他终端发送预设信息的反馈信息的时长的情况下，第四终端可以直接确定第三终端在接收到第四终端发送的预设信息后，响应预设信息所需的时间T0，从而可以根据可以确定向第三终端发送所述预设信息的第一时刻T1，以及接收到所述第三终端针对所述预设信息向所述第四终端发送响应信息的第二时刻T2，计算出第四终端到第三终端的距离d，例如如上述实施例所述，d＝(T2-T1-T0)c/2。
可选地，所述预设信息为同步信号，所述响应预设信息所需的时间包括：
所述第三终端接收到其他终端发送的同步信号的时刻相对所述第三终端的同步定时栅格的偏差值，以及所述第三终端向其他终端发送同步信号的时刻相对所述第三终端的同步定时栅格的偏差值。
在一个实施例中，其他终端包括但不限于第四终端，预设信息包括但不限于同步信号。
在响应预设信息所需的时间为所述第三终端接收到第四终端发送的同步信号的时刻相对所述第三终端的同步定时栅格的偏差值，以及第三终端向第四终端发送同步信号的时刻相对所述第三终端的同步定时栅格的偏差值的情况下，第四终端为了确 定第三终端到第四终端的距离，还需要确定第四终端向第三终端发送同步信号的时刻相对于第四终端的同步定时栅格的偏差值，以及第四终端接收到第三终端发送的同步信号的时刻相对于第四终端的同步定时栅格的偏差值。
例如第四终端向第三终端发送同步信号的时刻相对于第四终端的同步定时栅格(slot n,symbol l)的偏差值为t1，第三终端接收到第四终端发送的同步信号的时刻相对所述第三终端的同步定时栅格(slot n,symbol l)的偏差值为t2，第三终端向第四终端发送同步信号的时刻相对所述第三终端的同步定时栅格(slot m,symbol k)的偏差值为t3，第四终端接收到第三终端发送的同步信号的时刻相对于第四终端的同步定时栅格(slot m,symbol k)的偏差值为t4，其中m和n可以理解为时隙号，l和k可以理解为时隙中的第几个符号。
那么同步信号从第四终端发送至第三终端，第三终端接收同步信号后向第四终端发送响应信息，所述响应信息可以为同步信号，进而第四终端接收到第三终端发送的响应信息的总时长就等于RD_time＝(m-n)*T_slot+(k-l)*T_sym+(t1+t4)，第三终端从接收到第四终端发送的同步信号，到向第四终端发送同步信号的时长为Reply_time＝(m-n)*T_slot+(k-l)*T_sym-(t2+t3)，其中，T_slot标识时隙slot的时长，T_sym标识符号symbol的时长。
那么同步信号在第四终端和第三终端往返传输的时长就等于RD_time-Reply_time＝t1+t2+t3+t4，那么第四终端到第三终端的距离d＝(t1+t2+t3+t4)c/2。
可选地，所述处理能力信息包括标识和/或数值，其中，所述数值用于指示所述第三终端响应预设信息所需的时间，所述标识用于指示所述第三终端具备将响应预设信息所需的时间确定为固定值的能力。
在一个实施例中，处理能力信息可以包括以下至少一个：

数值，用于指示所述第三终端响应预设信息所需的时间。
其中，所述数值用于指示所述第三终端响应预设信息所需的时间，所述标识用于指示所述第三终端具备将响应预设信息所需的时间确定为固定值的能力，也即在处理能力信息中包含所述标识的情况下，第三终端每次响应预设信息所需的时间是固定值，那么第四终端只需接收到一次第三终端发送的所述第三终端响应预设信息所需的 时间即可，后续都可以按照该固定值来接收第三终端针对第四终端发送的预设信息的响应。
而在所述处理能力信息中不包括所述标识，仅包括数值的情况下，表示第三终端不具备固定应答时间的能力，所述数值虽然仍能表示所述第三终端响应预设信息所需的时间，但是所表示的时间相对粗略，第四终端并不能将该数值直接应用于后续感知过程，只能初步确定第三终端针对第四终端发送的预设信息的响应所需要的时间。
例如在处理能力信息中只有数值，没有标识，第四终端可以确定所述数值表示第三终端发送的针对第一终端发送的预设信息的确认信息的时间间隔，例如第三终端收到第四终端发送的感知参考信号ranging signal,然后向第四终端发送确认消息所需要的时间，该时间不是精确的应答时间；例如处理能力信息中既有数据，又有标识，第四终端可以确定所述数值表示第三终端响应来自所述第四终端的预设信息所需的时间。
图8是根据本公开的实施例示出的一种处理能力接收方法的示意流程图。本实施例所述的方法可以适用于第四终端，所述第四终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等电子设备。以下实施例中的第三终端，可以是上述处理能力发送方法所适用的第三终端。
如图8所示，所述处理能力接收方法可以包括以下步骤：
在步骤S401中，接收第三终端广播的第三消息，其中，所述第三消息中携带所述第三终端的处理能力信息。
在一个实施例中，由于第三终端并不知道附近存在哪些终端，也不知道附近哪些终端支持基于感知的服务的设备，所以可以通过广播的方式发送第三消息，以确保附近的终端都能够接收到第三消息。
在第三消息中可以携带有第三终端的处理能力信息，第四终端在接收到第三消息后，若第四终端支持基于感知的服务，可以根据第三消息中第三终端的处理能力信息，确定第三终端响应感知信息所需要的时间，以便第四终端与第三终端进行后续感知过程，进一步确定第三终端到第四终端的距离，以便与第三终端进行基于感知的服务。
需要说明的是，第四终端与前述实施例中的第二终端可以是相同的终端，其中第二终端是以终端作为被发现设备的角度进行描述，第四终端是以终端作为发现终端 的角度进行描述。
可选地，所述处理能力信息包括以下至少之一：
单位时间内处理数据的数据量、响应预设信息所需的时间
在一个实施例中，在处理能力信息为单位时间内处理数据的数据量时，第四终端根据单位时间内处理数据的数据量，可以计算出第三终端响应预设信息所需的时间，进而根据响应预设信息所需的时间确定接收第三终端响应信息的目标时刻，以便与第三终端进行后续通信，还可以进一步确定第三终端到第四终端的距离。
可选地，所述预设信息包括预设业务的请求信息或预设业务的参考信号，所述响应预设信息所需的时间包括：
所述第三终端从接收到其他终端发送的所述预设信息，到向所述其他终端发送所述预设信息的反馈信息的时长。
在一个实施例中，其他终端包括但不限于第四终端，预设信息包括但不限于感知请求消息和/或感知参考信号。
在响应预设信息所需的时间为第三终端从接收到其他终端发送的预设信息，到向其他终端发送预设信息的反馈信息的时长的情况下，第四终端可以直接确定第三终端在接收到第四终端发送的预设信息后，响应预设信息所需的时间T0，从而可以根据可以确定向第三终端发送所述预设信息的第一时刻T1，以及接收到所述第三终端针对所述预设信息向所述第四终端发送响应信息的第二时刻T2，计算出第四终端到第三终端的距离d，例如如上述实施例所述，d＝(T2-T1-T0)c/2。
可选地，所述预设信息为同步信号，所述响应预设信息所需的时间包括：
所述第三终端接收到其他终端发送的同步信号的时刻相对所述第三终端的同步定时栅格的偏差值，以及所述第三终端向其他终端发送同步信号的时刻相对所述第三终端的同步定时栅格的偏差值。
在一个实施例中，其他终端包括但不限于第四终端，预设信息包括但不限于同步信号。
在响应预设信息所需的时间为所述第三终端接收到第四终端发送的同步信号的时刻相对所述第三终端的同步定时栅格的偏差值，以及第三终端向第四终端发送同步信号的时刻相对所述第三终端的同步定时栅格的偏差值的情况下，第四终端为了确 定第三终端到第四终端的距离，还需要确定第四终端向第三终端发送同步信号的时刻相对于第四终端的同步定时栅格的偏差值，以及第四终端接收到第三终端发送的同步信号的时刻相对于第四终端的同步定时栅格的偏差值。
例如第四终端向第三终端发送同步信号的时刻相对于第四终端的同步定时栅格(slot n,symbol l)的偏差值为t1，第三终端接收到第四终端发送的同步信号的时刻相对所述第三终端的同步定时栅格(slot n,symbol l)的偏差值为t2，第三终端向第四终端发送同步信号的时刻相对所述第三终端的同步定时栅格(slot m,symbol k)的偏差值为t3，第四终端接收到第三终端发送的同步信号的时刻相对于第四终端的同步定时栅格(slot m,symbol k)的偏差值为t4，其中m和n可以理解为时隙号，l和k可以理解为时隙中的第几个符号。
那么同步信号从第四终端发送至第三终端，第三终端接收同步信号后向第四终端发送响应信息，所述响应信息可以为同步信号，进而第四终端接收到第三终端发送的响应信息的总时长就等于RD_time＝(m-n)*T_slot+(k-l)*T_sym+(t1+t4)，第三终端从接收到第四终端发送的同步信号，到向第四终端发送同步信号的时长为Reply_time＝(m-n)*T_slot+(k-l)*T_sym-(t2+t3)，其中，T_slot标识时隙slot的时长，T_sym标识符号symbol的时长。
那么同步信号在第一终端和第二终端往返传输的时长就等于RD_time-Reply_time＝t1+t2+t3+t4，那么第一终端到第二终端的距离d＝(t1+t2+t3+t4)c/2。
可选地，所述处理能力信息包括以下至少一个：
标识，用于指示所述第三终端具备将响应预设信息所需的时间确定为固定值的能力；
数值，用于指示所述第三终端响应预设信息所需的时间。
其中，所述数值用于指示所述第三终端响应预设信息所需的时间，所述标识用于指示所述第三终端具备将响应预设信息所需的时间确定为固定值的能力，也即在处理能力信息中包含所述标识的情况下，第三终端每次响应预设信息所需的时间是固定值，那么第四终端只需接收到一次第三终端发送的所述第三终端响应预设信息所需的时间即可，后续都可以按照该固定值来接收第三终端针对第四终端发送的预设信息的响应。
而在所述处理能力信息中不包括所述标识，仅包括数值的情况下，表示第三终 端不具备固定应答时间的能力，所述数值虽然仍能表示所述第三终端响应预设信息所需的时间，但是所表示的时间相对粗略，第四终端并不能将该数值直接应用于后续感知过程，只能初步确定第三终端针对第四终端发送的预设信息的响应所需要的时间。
例如在处理能力信息中只有数值，没有标识，第四终端可以确定所述数值表示第三终端发送的针对第一终端发送的预设信息的确认信息的时间间隔，例如第三终端收到第四终端发送的感知参考信号ranging signal,然后向第四终端发送确认消息所需要的时间，该时间不是精确的应答时间；例如处理能力信息中既有数据，又有标识，第四终端可以确定所述数值表示第三终端响应来自所述第四终端的预设信息所需的时间。
图9是根据本公开的实施例示出的另一种处理能力接收方法的示意流程图。如图9所示，所述方法还包括：
在步骤S402中，响应于所述处理能力信息包括所述标识和所述数值，确定所述第三终端具备将响应预设信息所需的时间确定为固定值的能力，且所述固定值为所述数值；
在步骤S403中，根据所述数值确定接收所述第三终端发送的针对所述第四终端发送的预设信息的确认信息的目标时刻。
在一个实施例中，在处理能力信息包括标识和数值的情况下，第四终端可以确定所述第三终端具备将响应预设信息所需的时间确定为固定值的能力，且所述固定值为所述数值，并且处理能力信息中的数值表征所述第三终端响应来自所述第四终端的预设信息所需的时间，那么在后续感知过程中，第四终端可以根据所述数值确定接收所述第三终端发送的针对所述第四终端发送的预设信息的确认信息的目标时刻，进而可以在目标时刻接收所述第三终端发送的确认信息，并且在感知过程中可以直接利用所述数值，不需要第二终端再次向第一终端发送响应预设信息所需要的时间。
由于第三终端具备将响应预设信息所需的时间确定为固定值的能力，所以第三终端响应预设信息所需的时间是固定的，那么第三终端只需向第四终端发送一次所述数值来表示所述固定值即可，后续可以不必再向第四终端发送第三终端响应预设信息所需的时间。
需要说明的是，在本实施例以及其他实施例中，第三终端发送的针对所述第四终端发送的预设信息的确认信息，可以是针对第四终端发送的感知请求消息和/或感知 参考信号的确认信息。
图10是根据本公开的实施例示出的又一种处理能力接收方法的示意流程图。如图10所示，所述处理能力信息包括数值，所述方法还包括：
在步骤S404中，响应于所述处理能力信息包括所述数值且不包括所述标识，确定所述第三终端不具备将响应预设信息所需的时间确定为固定值的能力；
在步骤S405中，根据所述数值确定接收所述第三终端发送的针对所述第四终端发送的预设信息的确认信息的时间间隔。
在一个实施例中，在处理能力信息包括数值而不包括标识的情况下，第四终端可以确定第二终端不具备将响应预设信息所需的时间确定为固定值的能力，以及确定处理能力信息中的数值所表示的所述第二终端响应预设信息所需的时间相对粗略，那么第四终端根据所述数值并不能准确地确定上述实施例中的目标时刻，但是可以确定第三终端发送的针对所述第四终端发送的预设信息的确认信息的时间间隔，例如时间间隔大于或等于所述数值对应的时间，从而可以根据所述时间间隔接收所述第三终端发送的确认信息，以免过于频繁地尝试接收第三终端发送的确认信息而造成电量浪费。并且在后续感知过程中，第二终端还还需要向第一终端发送准备且的响应预设信息所需要的时间。
进一步地，为了使得第四终端能够确定具体的目标时刻，第三终端在发送确认信息时，可以将所述第三终端响应来自所述第四终端的预设信息所需的时间发送给第四终端。但是由于第三终端不具备将响应预设信息所需的时间确定为固定值的能力，所以第三终端响应预设信息所需的时间不是固定的，那么第三终端每次从第四终端接收到预设信息后，都需要重新确定第三终端响应预设信息所需的时间，进而将所确定的第三终端响应预设信息所需的时间发送至所述第四终端。
图11是根据本公开的实施例示出的又一种处理能力接收方法的示意流程图。如图11所示，所述处理能力信息包括标识，所述方法还包括：
在步骤S406中，响应于所述处理能力信息包括所述标识且不包括所述数值，确定所述第三终端具备将响应预设信息所需的时间确定为固定值的能力。
在一个实施例中，所述处理能力信息还可以只包括标识，在这种情况下，可以终端可以确定所述第三终端具备将响应预设信息所需的时间确定为固定值的能力，但是可能因为某些原因，例如通信资源不足，导致未能将标识和数值一同发给第四终端， 但是后续会将数值发送给第四终端，那么第四终端根据标识可以在后续与第三终端通信过程中，从第三终端接收第三终端响应预设信息所需的时间。
