具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
本公开实施例提供的直连通信方法可应用于图1所示的直连通信系统。参阅图1所示，直连通信设备之间进行直连通信的场景中，网络设备为直连通信设备1配置各种用于数据传输的传输参数。直连通信设备1作为数据发送端，直连通信设备2作为数据接收端，二者进行直接通信。网络设备与直连通信设备之间进行通信的链路为上下行链路，直连通信设备与直连通信设备之间的链路是直连链路(sidelink)。
本公开中，直连通信设备之间直接通信的通信场景也可以是终端到终端(Device to Device，D2D)的通信场景。本公开实施例中进行直接通信的直连通信设备可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile station，MS)，终端(terminal)，终端设备(Terminal Equipment)等等。为方便描述，本公开实施例以下以直连通信设备为用户设备为例进行说明。
目前，NR直连通信系统中的物理层信道包括物理直连广播信道(Physical Sidelink Broadcast Channel，PSBCH)，物理直连共享信道(Physical Sidelink Share Channel，PSSCH)，物理直连控制信道(Physical Sidelink Control Channel，PSCCH)和物理直连反馈信道(Physical Sidelink Feedback Channel，PSFCH)；物理层参考信号包括主直连同步信号(Primary Sidelink Synchronization Signal，PSSS)，辅助直连同步信号(Secondary Sidelink Synchronization Signal，SSSS)，解调参考信号(Demodulation Reference Signal，DMRS)，信道状态指示参考信号(Channel-state information Reference Signal，CSI-RS)，相位调制参 考信号(Phase Tracking Reference Signal，PT-RS)等。由于已有NR直连通信系统并没有考虑到通过直连信号测距的需求，故由于设计目的不同，NR直连通信系统中目前已有的信道或参考信号均不适合用作测距使用。对于通过直连信号测距需要设计专用的直连测距信号以及直连测距资源。
对于sidelink测距或定位，测距信号发送端发送直连测距信号，而测距信号接收端根据直连测距信号进行测量，通过时间测量或者角度测量等方法确定发送端和接收端之间的距离和/或角度。与NR测距中定位参考信号的发送和接收的其中一端为基站不同，直连测距或定位的发送端和接收端均为用户设备。
对于直连测距的用户设备，可能处于基站覆盖范围之内，也可能处于基站覆盖范围之外。即使处于基站覆盖范围之内，也有可能处于无线资源控制(Radio Resource Control，RRC)空闲(idle)状态，因此无法完全依赖基站配置或指示来决定用于直连测距或定位的直连测距资源。
本公开实施例提供一种直连通信方法，在该直连通信方法中，用户设备使用直连测距资源集中的直连测距资源发送直连测距信号，进而实现直连测距资源的分配，并进行直连测距。
图2是根据一示例性实施例示出的一种直连通信方法的流程图，如图2所示，直连通信方法用于用户设备中，包括以下步骤。
在步骤S11中，确定直连测距资源集配置参数。
本公开实施例中，直连测距资源配置参数可以理解为是用于确定直连测距资源集(也称为直连测距资源集合)的配置参数。
在步骤S12中，基于直连测距资源集配置参数，确定直连测距资源。
本公开实施例中，直连测距资源有时也可以称为是直连ranging资源，本公开实施例中二者有时交替使用，本领域技术人员应理解其含义的一致性。
其中，直连测距资源可以是频率资源，也可以是时间资源，或者也可以是时间资源和频率资源。
在步骤S13中，通过直连测距资源传输直连测距信号。
本公开实施例中，直连测距信号可以理解为是在基于sidelink进行通信的用户设备间，用于直连测距或定位的信号。用户设备间能够对该直连测距信号进行测量，通过时间测量或者角度测量等方法确定用户设备之间的距离和/或角度。
本公开实施例提供的直连通信方法中，用户设备基于直连测距资源集配置参数确定直连测距资源，并通过直连测距资源传输直连测距信号，进而实现用户设备使用直连测距资 源集中的直连测距资源发送直连测距信号，故可以实现直连测距资源的确定并有效的进行直连测距。
本公开实施例提供的直连通信方法中，用户设备进行直连测距使用的直连测距资源集可以是周期性的直连测距资源集合。即，直连测距资源集配置参数所配置的直连测距资源集为周期性直连测距资源集。
一种实施方式中，周期性直连测距资源集在每一资源周期内包括一组或多组直连测距资源，且每一组直连测距资源中包括一个或多个直连测距资源，每一个直连测距资源为处于同一时间单元内的资源。其中，时间单元可以是时隙，子帧和符号等。
本公开实施例提供的直连通信方法中，周期性直连测距资源集中同一组内的每个直连测距资源在时间单元内的位置和大小相同。
本公开实施例提供的直连通信方法中，周期性直连测距资源集中同一资源周期内包括多组直连测距资源。多组直连测距资源采用时分方式复用时域资源，和/或采用频分方式复用频域资源。
一示例中，直连测距资源集为周期性的直连测距资源集合；每个周期内存在一组或多组直连ranging资源；每组直连ranging资源包括一个或多个直连ranging资源；每个直连ranging资源在一个时间单元内；同一组内的每个直连ranging时间频率资源在时间单元内的位置和大小相同。不同组的直连ranging资源可以通过时分或频分的方法进行复用。
本公开实施例提供的直连通信方法中，不同组的直连ranging资源采用频分复用方式进行复用时，可以采用梳状(comb)频分复用方式复用频域资源。其中，采用梳状频分复用方式复用频域资源时，基于梳状频分复用因子复用频域资源。其中，梳状频分复用因子用于指示采用梳状频分复用方式复用频域资源时占用的资源元素(Resource Element，RE)的配置信息。比如，配置信息可以包括RE数量，和/或相邻两个RE之间的间隔。
本公开实施例中，一个用户设备可以被配置多个直连测距资源集，每个直连测距资源集对应的直连测距资源集配置参数可以不同。例如，每个直连测距资源集对应的梳状频分复用因子可以不同。
一种实施方式中，直连测距资源集配置参数用于配置多个不同的直连测距资源集。
一种实施方式中，直连测距资源集配置参数中包括梳状频分复用因子，不同直连测距资源集的梳状频分复用因子不同。
本公开实施例提供的直连通信方法中，响应于一个用户设备被配置多个直连测距资源集，用户设备可以接收网络设备的下行信令指示，或者根据用户设备高层指示或ranging服务特性(如距离、精确度、延时要求等)选择合适的直连测距资源集。
本公开实施例一种实施方式中，用户设备确定的直连测距资源集配置参数可以包括以下至少一项：
周期长度；
周期内每组直连测距资源的个数和时域间隔；
周期内每组直连测距资源在时间单元内的时域起始位置和时域长度；
周期内每组直连测距资源在时间单元内的频域起始位置和频域长度。
本公开实施例提供的直连通信方法中，用户设备可以通过接收网络设备发送的下行信号、预配置或者预定义的方法得到直连测距资源集配置参数，即用户设备确定直连测距资源集配置参数可以采用如下方式之一：
方式一：接收网络设备发送的下行信号，根据下行信号确定直连测距资源集配置参数。
其中，本公开实施例中网络设备发送的下行信号可以是下行控制信息(Downlink Control Information，DCI)。以下为描述方便，将用于确定直连测距资源集配置参数的DCI称为第一DCI。
图3是根据一示例性实施例示出的一种直连通信方法的流程图，如图3所示，直连通信方法用于用户设备中，包括以下步骤。
在步骤S21中，接收网络设备发送的第一DCI。
在步骤S22中，根据第一DCI确定直连测距资源集配置参数。
方式二：基于预配置信息(预配置或者预定义)，确定直连测距资源集配置参数。
以下为描述方便，将用于确定直连测距资源集配置参数的预配置信息称为第一预配置信息。
图4是根据一示例性实施例示出的一种直连通信方法的流程图，如图4所示，直连通信方法用于用户设备中，包括以下步骤。
在步骤S31中，基于第一预配置信息，确定直连测距资源集配置参数。
本公开提供的直连通信方法中，基于第一DCI或者第一预配置信息确定的直连测距资源集配置参数，用于指示直连测距资源集。例如，直连测距资源集配置参数用于指示周期性的直连测距资源集合中各ranging资源集合的周期长度；周期内每组直连ranging资源的个数和时域间隔；周期内每组直连ranging资源在时间单元内的时域起始位置和时域长度；周期内每组直连ranging资源在时间单元内的频域起始位置和频域长度。进而使得，用户设备基于直连测距资源集配置参数可以确定直连测距资源集。
本公开实施例提供的直连通信方法中，用户设备可以基于网络设备发送的下行控制信号，或者根据自主选择确定使用直连测距资源集中的特定直连测距资源发送直连测距信 号。
本公开实施例中为描述方便，将用于用户设备在直连测距资源集汇总确定直连测距资源的下行控制信号称为第二DCI。其中，该DCI可以是半静态RRC信令，或者动态DCI信令。
图5是根据一示例性实施例示出的一种直连通信方法的流程图，如图5所示，直连通信方法用于用户设备中，包括以下步骤。
在步骤S41中，接收网络设备发送的第二DCI。
在步骤S42中，根据第二DCI在直连测距资源配置参数配置的直连测距资源集中确定直连测距资源。
图6是根据一示例性实施例示出的一种直连通信方法的流程图，如图6所示，直连通信方法用于用户设备中，包括以下步骤。
在步骤S51中，基于预定义规则，在直连测距资源配置参数配置的直连测距资源集中确定直连测距资源。
本公开实施例提供的直连通信方法中，直连测距资源集可以是一个或多个。其中，当直连测距资源集为多个的情况下，多个直连测距资源集可以为不同的直连测距资源集。
其中，用于确定多个不同直连测距资源集的直连测距资源配置参数可以为一个或多个。即，一方面，可以通过一个直连测距资源配置参数配置多个不同的直连测距资源集，换言之直连测距资源集配置参数可以是一对多的关系。另一方面，也可以通过多个不同的直连测距资源集配置参数配置多个不同的直连测距资源集。其中，直连测距资源集配置参数与直连测距资源集之间可以是一对一的对应关系(一个直连测距资源集配置参数配置一个直连测距资源集)，也可以是一对多的对应关系(一个直连测距资源集配置参数配置多个直连测距资源集)。
本公开实施例提供的直连通信方法中，用户设备根据不同的资源选择方法，如基站分配或者用户设备自选，可以为用户设备设置不同的直连测距资源集配置参数，以用于确定传输直连测距信号的直连测距资源。一示例中，用户设备被配置有两个直连测距资源集配置参数，分别为直连测距资源集配置参数1和直连测距资源集配置参数2。在进行直连测距资源确定时，一方面，如果通过基站分配，则可以使用资源集配置参数1进行直连测距资源确定。另一方面，如果用户设备自选，则可以使用资源集配置参数2进行直连测距资源确定。
本公开实施例提供的直连通信方法中，用户设备确定了直连测距资源后，可以通过直连测距资源传输直连测距信号，并进行直连测距。
图7是根据一示例性实施例示出的一种直连通信方法的流程图，如图7所示，直连通信方法用于用户设备中，包括以下步骤。
在步骤S61中，基于同一直连测距资源传输不同的直连测距信号。
一种实施方式中，用户设备可以基于同一直连测距资源传输不同的直连测距信号，即针对不同的直连测距信号复用直连测距资源。
其中，复用直连测距资源可以采用时分复用方式复用时域资源，也可以采用频分复用方式复用频域资源。
本公开实施例提供的一种直连通信方法中，用户设备可以在同一直连测距资源汇总采用梳状频分复用方式复用频域资源。
图8是根据一示例性实施例示出的一种直连通信方法的流程图，如图8所示，直连通信方法用于用户设备中，包括以下步骤。
在步骤S71中，在同一直连测距资源中采用梳状频分复用方式复用频域资源。
其中，采用梳状频分复用方式复用频域资源时，可以基于梳状频分复用因子复用频域资源。其中，梳状频分复用因子用于指示采用梳状频分复用方式复用频域资源时占用的RE的配置信息。比如，配置信息可以包括RE数量，和/或相邻两个RE之间的间隔。
换言之，本公开实施例提供的直连通信方法中，在每个直连ranging资源内传输的不同直连ranging信号可以通过频域comb的方式进行复用传输。
本公开实施例提供的直连通信方法中，用户设备通过频域comb的方式进行复用传输时，需要进行梳状频分复用因子的确定。
本公开实施例提供的直连通信方法中，用户设备可以基于网络设备发送的下行信号、预配置或者预定义的方法，确定梳状频分复用因子。梳状频分复用因子用于指示采用梳状频分复用方式复用频域资源时占用的资源元素的配置信息。
其中，本公开实施例中一方面，将用于确定梳状频分复用因子的下行控制信号称为第三DCI，即，用户设备可以根据第三DCI确定梳状频分复用因子。
图9是根据一示例性实施例示出的一种直连通信方法的流程图，如图9所示，直连通信方法用于用户设备中，包括以下步骤。
在步骤S81中，接收网络设备发送的第三DCI，根据第三DCI确定梳状频分复用因子。
另一方面，将用于确定梳状频分复用因子的预配置信息称为第二预配置信息，即，用户设备可以根据第二预配置信息确定梳状频分复用因子。
图10是根据一示例性实施例示出的一种直连通信方法的流程图，如图10所示，直连 通信方法用于用户设备中，包括以下步骤。
在步骤S91中，基于第二预配置信息，确定梳状频分复用因子。
本公开实施例提供的直连通信方法中，第三DCI和/或第二预配置信息可以用于配置针对每一个直连测距资源的梳状频分复用因子，或者用于配置针对直连测距资源集合的梳状频分复用因子。
一示例中，梳状频分复用因子的确定可以采用如下方式：
方式一：通过接收网络设备下行信号、预配置或者预定义的方法，得到comb复用因子。
方式二：通过接收网络设备下行信号、预配置或者预定义的方法，得到一组comb复用因子，由直连ranging信号发送端用户设备选择具体使用哪个comb值
本公开实施例提供的直连通信方法中，在每个直连ranging资源内传输的不同直连ranging信号可以通过频域comb的方式进行复用传输。Comb复用因子的配置可以是基于每个直连ranging资源集配置的，也可能根据直连ranging资源集所属于的直连资源集合(如直连资源池或直连带宽部分(bandwidth part，BWP))配置的。
本公开实施例提供的直连通信方法中，在每个直连ranging资源内传输直连测距信号时，为使直连测距信号能够占据更多的带宽资源，可以采用以下至少一种方式进行直连测距信号传输：
方式一：采用与直连测距资源集频域宽度相同的直连测距资源，传输直连测距信号。即，当用户设备在特定直连ranging资源集中的直连ranging资源发送直连ranging信号时，所发送直连ranging信号的频域带宽和直连ranging资源的频域宽度相同。
方式二：采用与直连测距信号时域长度相同的直连测距资源，传输直连测距信号。即，ranging信号时域长度和资源的时域长度相同。
本公开实施例一种实施方式中，考虑用于自动增益控制(automatic gain control，AGC)调整和/或保护间隔的时域符号，可以在直连测距资源中去除用于AGC调整和/或保护间隔的时域符号之后，尽量占据更多的直连测距资源。
方式三：采用直连测距资源集周期整数倍对应的周期，传输直连测距信号。即，Ranging信号的发送周期等于资源集周期或者为资源集周期的整数倍。
方式四：在同一周期内的一组直连测距资源内重复传输直连测距信号，且重复传输直连测距信号的次数小于或等于对应组内直连测距资源的个数。即，每周期内ranging信号可以在周期内的一组ranging资源内重复发送；重复发送的次数不超过该组ranging资源的个数。
本公开实施例提供的直连链路通信方法中，通过配置上述方式在每个直连ranging资源内传输直连测距信号，可以理解为是提供了一种新的直连测距信号的格式，该格式可以使直连测距信号能够占据更多的带宽资源。
本公开实施例提供的直连链路通信方法，通过配置直连测距资源集，并使用直连测距资源集中的直连测距资源进行直连测距信号传输，能够无需依赖网络设备配置或指示来确定时间频率资源以及直连测距信号传输的格式，而使用适用于直连链路通信的用户设备间进行测距使用的直连测距信号占用的时频资源和直连测距信号格式进行直连测距。
需要说明的是，本领域内技术人员可以理解，本公开实施例上述涉及的各种实施方式/实施例中可以配合前述的实施例使用，也可以是独立使用。无论是单独使用还是配合前述的实施例一起使用，其实现原理类似。本公开实施中，部分实施例中是以一起使用的实施方式进行说明的；当然，本领域内技术人员可以理解，这样的举例说明并非对本公开实施例的限定。
基于相同的构思，本公开实施例还提供一种直连通信装置。
可以理解的是，本公开实施例提供的直连通信装置为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。结合本公开实施例中所公开的各示例的单元及算法步骤，本公开实施例能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。本领域技术人员可以对每个特定的应用来使用不同的方法来实现所描述的功能，但是这种实现不应认为超出本公开实施例的技术方案的范围。
