具体实施方式
下面详细描述本申请的实施例，实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
为了便于理解，首先介绍本申请涉及的术语。
1、时分复用技术(Time-Division Multiplexing,TDM)
时分复用技术将不同的信号相互交织在不同的时间段内，沿着同一个信道传输；在接收端再用某种方法，将各个时间段内的信号提取出来还原成原始信号的通信技术。这种技术可以在同一个信道上传输多路信号。
2、频分复用技术(Frequency-Division Multiplexing，FDM)
频分复用技术就是将用于传输信道的总带宽划分成若干个子频带(或称子信道)，每一个子信道传输一路信号。频分复用要求总频率宽度大于各个子信道频率之和，同时为了保证各子信道中所传输的信号互不干扰，应在各子信道之间设立隔离带，这样就保证了各路信号互不干扰。
为了更好的理解本申请实施例提出的一种直连测距的资源复用方法，下面首先对本申请实施例使用的通信系统进行描述。

本申请实施例中的发送终端设备101和接收终端设备102可以是用户侧的一种用于接收或发射信号的实体，如手机。发送终端设备101和接收终端设备102也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端设备(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving) 中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
可以理解的是，本申请实施例描述的通信系统是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提出的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本申请实施例提出的技术方案对于类似的技术问题，同样适用。

S10，在同一个时间单元内，对直连测距信号和物理直连信道通过频分复用和/或时分复用的方式进行第一直连传输。
随着终端之间的直连通信的发展，基于终端设备之间距离和角度的应用和服务正在不断涌现，例如，可以被应用在包括商品展示，智能家居，智慧城市，智慧交通，智能零售等多种商业和垂直应用场景中。因此，通过无线信号进行距离和角度的测量被急需解决。通过无线信号进行距离和/或角度的测量可以有效地利用终端设备的无线通信能力，并引入新的终端设备能力。实现中，发送终端可以向接收终端发送直连测距信号，接收终端可以基于直连测距信号进行距离和/或角度的测量，也就是说，直连测距信号为用于测量距离或者角度的参考信号。
为了支持直连测距信号的时频资源的动态分配以及时频资源的利用率，发送终端除了发送直连测距信号，还可以与处于同一时间单元内的另外的物理直连信道进行资源复用。可选地，同一时间单元可以为同一时隙，也可以为连续的几个时域符号或者单个时域符号。

其中，第一直连控制信息、第二直连控制信息与直连数据传输和/或直连测距信号传输相关；第一物理直连信道，第二物理直连信道和/或直连测距信号传输相关联。
在对直连测距信号和物理直连信道进行复用传输时，可以将在同一个时间单元内的直连测距信号和物理直连信道，通过频分复用的方式进行第一直连传输，也就是说，可以将直连测距信号与第一物理直连信道和/或第二物理直连信道，通过频分复用方式进行第一直连传输，如图3所示，即将直连测距信号1、第一物理直连信道2和第二物理直连信号3通过频分复用方式进行了资源复用，即直连测距信号1、第一物理直连信道2和第二物理直连信号3占用了同样的时间资源，但是在时间资源上占用了不同 的频率资源。
可选地，在对直连测距信号和物理直连信道进行复用传输时，可以将在相同频率上的直连测距信号和物理直连信道，通过时分复用的方式进行第一直连传输，也就是说，可以将直连测距信号与第一物理直连信道和/或第二物理直连信道，通过时分复用方式进行第一直连传输，如图4所示，即将直连测距信号1和第一物理直连信道2通过时分复用方式进行了资源复用，其中第一物理直连信道2占用一段时间资源的前一部分时间资源，直连测距信号1占用一段时间资源的后一部分时间资源。
可选地，在对直连测距信号和物理直连信道进行复用传输时，可以将在同一个时间单元内的直连测距信号和物理直连信道，通过频分和时分共同复用的方式进行第一直连传输，也就是说，可以将直连测距信号与第一物理直连信道和/或第二物理直连信道，通过频分和时分共同复用方式进行第一直连传输，如图5所示，即将直连测距信号1、第一物理直连信道2和第二物理直连信道3通过频分和时分共同复用方式进行了资源复用，其中，直连测距信号1和第二物理直连信道3进行时分复用，分别占用一段时间资源的一部分，并且还占用了该一段时间资源的不同频率资源，第一物理直连信道2也占用了不同的频率资源。
本申请实施例提出了一种直连测距的资源复用方法，通过在同一个时间单元内，对直连测距信号和物理直连信道通过频分复用和/或时分复用的方式进行第一直连传输，避免了直连测距信号和物理直连信道在传输时产生干扰，提升了传输性能。

可选地，将直连测距信号和物理直连信道映射到连续时间资源的不同时间资源位置上进行第一直连传输，可以在直连测距信号的传输和物理直连信道的传输之间设置保护间隔。其中，保护间隔可以通过预定义或预配置，确定保护间隔的长度；或者，根据第一直连传输使用的载波频率和/或子载波间隔确定保护间隔的长度。
可选地，第一直连传输在传输时间内每一个时域符号上的发送功率相等，以便保证接收用户的设备在每个时域符号上的接收功率相同，避免因射频放大器调整需要时间，而影响直连数据的接收效果。
可选地，每一个时域符号上所占用的频域资源相同，可选地，频域资源相同包括频域资源的起始位置和大小相同，以便直连测距信号的资源指示，同时避免由于发送功率谱密度的变化需要在直连控制信息和直连测距信号的传输之间引入发送切换时间。
在测量多个终端设备距离和角度的场景下，可选地，为了实现资源的较高利用率，可以对直连测距信号在占用的频率资源上通过梳状的方式进行复用。在一些实现中，可以以梳状的方式将直连测距信号和/或物理直连信道以梳状的方式映射到频域资源上。例如可以将直连测距信号和/或用于传输第一控制信息的第一物理直连信道通过梳状方式进行复用，下面以直连测距信号与用于传输第一控制信息的第一物理直连信道进行复用为例，对梳状复用进行解释说明，其中，第一控制信息可以直连测距信号对应的直连测距的控制信息。
其中，关于梳状映射，可通过预定义、预配置或者接收网络设备的下行控制信令，确定梳状复用因子，即确定梳状映射的频域间隔数。如图8所示，以梳状复用因子为2为例，当梳状复用因子为2时，梳状映射的频域间隔数为1，即每间隔一个频域进行一次映射。需要注意的是，直连测距信号和物理直连信道使用相同的梳状映射的频域间隔数。其中，直连测距信号梳状映射的初始频域偏移值和物理直连信道的梳状映射的初始频域偏移值存在确定的映射关系；或直连测距信号梳状映射的初始频域偏移值和物理直连信道的频域位置存在确定的映射关系。通过这种方法可以在保证参考信号传输带宽的条件下有效的提升资源的使用效率。参考信号传输带宽越宽，使用参考信号进行测距的精度一般就越高。
可选地，直连测距信号和直连测距信号复用传输的物理直连信道对应的梳状复用因子可以相同或不同，梳状复用的频域偏移也可以相同或不同。
可选地，用户设备可以通过接收基站下行信令配置或者读取预配置信息确定直连测距信号和直连测距信号复用传输的物理直连信道对应的梳状复用因子和频域偏移量。
可选地，直连测距信号和其对应的第一直连控制信息的第一直连传输可以通过时分的方式进行复用。其中，直连测距信号和其对应的第一直连控制信息所占用的频域资源相同。其中，传输直连测距信号和其对应的第一直连控制信息的时域符号之间设置有保护间隔。其中，直连测距信号的传输和物理直连信道的传输使用不同的传输功率；或者，直连测距信号的传输和物理直连信道的传输使用不同的频域带宽；或者直连测距信号的传输和物理直连信道的传输使用不同的天线配置和/或预编码矩阵。
在一些实现中，如图9和图10所示，直连测距信号的频域资源的位置和其对应的控制信息的梳状偏移值存在对应关系，保证不同频域位置对应的梳状偏移值不同，以保证控制信息和直连测距信号两者其中之一频域正交就都频域正交。
本申请实施例提出了一种直连测距的资源复用方法，通过时分复用方式，将直连测距信号和物理直 连信道映射到连续时间资源的不同时间资源位置上进行第一直连传输，提供时域资源的利用率，并且可以避免直连测距信号和物理直连信道在传输时产生干扰，提升了传输性能。
在同一时间单元内，对直连测距信号和物理直连信道通过频分复用的方式进行复用传输，图11为本申请另一实施例的直连测距的资源复用方法的流程示意图，该方法应用于发送终端，如图11所示，该方法包括：
S30，在第一物理直连信道占用的时间资源上，将直连测距信号和第一物理直连信道通过频分复用的方法进行第一直连传输。
可选地，第一物理直连信道用于传输第一直连控制信息，其中，第一直连控制信息可以为直连测距信号对应的控制信息。第一物理直连信道占用一个或多个时域资源，相应地，可以在该占用的一个或者多个时域资源上将直连测距信号和第一物理直连信道通过频分复用的方法进行第一直连传输。如图12所示，直连测距信号1和第一物理直连信道2的直连控制信息通过频分复用的方法进行第一直连传输。
在测量多个终端设备距离和角度的场景下，可选地，为了实现资源的较高利用率，可以对直连测距信号在占用的频率资源上通过梳状的方式进行复用。在一些实现中，直连测距信号对应的控制信息可以通过梳状方式进行复用，可以以梳状的方式将直连测距信号和直连测距信号复用传输的物理直连信道以梳状的方式映射到频域资源上。
在另一些实现中，直连测距信号和其对应的控制信息的传输可通过频分的方式进行复用。与上述相同，直连测距信号可以通过梳状的方式进行复用。如图13所示，直连测距信号对应的直连控制信息可以通过梳状方式进行复用。如图14所示，直连测距信号对应的直连控制信息可以通过频分的方式进行复用。
本申请实施例提出了一种直连测距的资源复用方法，通过在第一物理直连信道占用的时间资源上，将直连测距信号和第一物理直连信道通过频分复用的方法进行第一直连传输，提供时域资源的利用率，并且可以避免直连测距信号和物理直连信道在传输时产生干扰，提升了传输性能。

可选地，第一直连传输中传输的承载在第一物理直连信道上的第一直连控制信息和第二直连传输中传输的承载在第一物理直连信道上的第二直连控制信息的格式相同。可选地，将第一直连控制信息与第二直连控制信息映射到各自的第一物理直连信道的相同的时频资源位置上。
直连控制信息可在直连测距信号之前传输，以便减少接收端的处理时延。可选地，本申请实施例中，直连测距的控制信息可为两部分控制信息，分别为第一阶段控制信息(1 st stage SCI)和第二阶段控 制信息(2 nd stage SCI)。可选地，将第一直连控制信息作为直连测距信号对应的直连测距的控制信息，其中，该控制信息中包含直连测距信号使用的时间频率资源信息。
第一直连控制信息使用和直连数据传输对应的第一阶段SCI相同的第一物理直连信道进行传输，即直连测距的第一阶段SCI传输可能出现的时频资源位置的集合与直连数据传输对应的第一阶段SCI传输可能出现的时频资源位置集合相等或是其子集。这样用户设备可以通过同样的第一物理直连信道监听过程，即可得知周围设备的直连数据传输资源占用情况，也可得知直连测距传输资源占用情况，有利于用户设备进行灵活的资源选择以避免直连测距信号和直连数据传输之间的冲突。
响应于第一直连控制信息未包括第二阶段SCI，且第一直连控制信息的第一阶段SCI占用的频率资源小于直连测距信号占用的频率资源，则确定第一阶段SCI所占用的目标时域符号，并将部分直连测距信号映射到目标时域符号上未被第一阶段SCI占用的剩余资源单元RE上。需要说明的是，在目标时域符号上，可以使用较短的生成序列，或者将原来预计映射在被SCI占用的RE上的测距信号敲掉(puncture)。
响应于第一直连控制信息中包括第二阶段SCI，将第二阶段SCI映射到目标时域符号上未被第一阶段SCI占用的剩余RE上，如图17所示；或者，将第二阶段SCI映射到位于目标时域符号之后的连续时域符号上，如图18所示。
可选地，第一直连传输的频域资源分配粒度为第二直连传输的最小频域资源分配粒度的整数倍，以便用户设备同时对两者的资源使用进行监听。
