Abstract

Description

一种连续多时隙的传输方法、装置及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种连续多时隙的传输方法、装置及存储介质。
背景技术
相关技术中，在直连链路(sidelink)的非授权频段下，当两个终端进行通信传输时，在相应的时隙(slot)先进行先听后说(listen before talk，LBT)，以便确定信道是否可用。当LBT成功后可以选择单个时隙进行数据传输，或者选择多个时隙进行传输。相应的，当在一次LBT成功后，可以支持连续的多个时隙的传输，则可以通过更少的LBT次数，以减少LBT失败所带来的影响。
然而，在sidelink的时隙结构中，每个时隙中至少存在一个保护符号(guard symbol)或称保护间隔(guard period，GP)。并且，在现有的通信协议下规定了在guard symbol处不传输数据，而是进行收发转换或发收转换。这使得终端无法实现连续多时隙的传输。而是在一个时隙的guard symbol处传输中断，在下一个时隙的传输开始前，终端需要再次进行LBT。这导致了连续多时隙的传输无法实现。

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。
本公开实施例提供的连续多时隙数据发送方法可应用于图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，直连通信设备2和直连通信设备3进行直连通信。不同的直连通信设备之间可以存在障碍物，也可以不存在障碍物。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，不同的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可以是车用无线通信技术(Vehicle to Everything，V2X)业务场景。其中，V代表车载设备，X代表任何与车载设备交互的对象。当前X主要包含车载设备、手持设备、交通路侧基础设施和网络。V2X交互的信息模式包括：车载设备与车载设备之间(Vehicle to Vehicle，V2V)、车载设备与路边设备之间(Vehicle to Infrastructure，V2I)、车载设备与手持设备之间(Vehicle to Pedestrian，V2P)、车载设备与网络之间(Vehicle to Network，V2N)的交互。
随着新一代5G移动通信技术的发展，在3GPP Rel-16中利用5G NR技术实现了对新的V2x通信服务和场景的支持，如车队管理(Vehicles Platooning)，感知扩展(Extended Sensors)，先进驾驶(Advanced Driving)，和远程驾驶(remote driving)等。总体来说，5G V2x sidelink能够提供更高的通信速率，更短的通信延时，更可靠的通信质量。
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。可以理解，用户设备也可以称为终端。
相关技术中，在sidelink非授权频段下(即sl-u)，两个终端进行相互通信传输时，通 常会在相应的时隙(slot)资源上先进行LBT，以确定相应的信道是否可用。例如图2所示出的，一种基于LBT进行数据传输示意图。可以看出，当LBT成功后可以选择单个时隙资源进行数据传输，也可以选择多个时隙资源进行数据传输。例如图2中白色框对应的LBT，例如图2中左侧的LBT成功后选择了单个时隙资源进行数据传输。又例如图2中右侧的LBT成功后选择了多个时隙资源进行数据传输。而当LBT失败后，则无法进行资源选择，从而导致通信失败或无法通信。在一些情况下，当在一次LBT成功后可以支持连续的多个时隙资源的数据发送，使得可以通过更少的LBT次数，以减少LBT失败所带来的对通信造成的影响。
但是在目前的sidelink时隙结构中，例如图3所示出的，每个时隙中至少存在一个guard symbol或称GP。例如每一个时隙中用于sidelink传输的最后一个符号。或者在配置了物理直连链路反馈信道(physical sidelink feedback channel，PSFCH)时，每个用于sidelink传输的时隙还会额外存在一个用于PSFCH的GP符号。
在现有的R16/R17协议中规定了在guard symbol处不传输数据，而是进行收发转换或发收转换。通常一个guard symbol长度大于16微秒(us)或25us。这会导致终端无法实现连续多时隙的传输。例如，在一个时隙的guard symbol信道被例如WiFi设备占用，导致终端传输中断，终端需要在下一个时隙的传输开始前，再次进行LBT。
显然，由于guard symbol的存在，使得连续多时隙传输无法实现。
因此，本公开提供了一种连续多时隙的传输方法，通过在连续多个时隙中非最后一个时隙的最后一个符号上发送数据，使得终端可以实现连续多个时隙的数据传输。
图4是根据一示例性实施例示出的一种连续多时隙的传输方法流程图，如图4所示，该方法用于第一终端，包括以下步骤。
在步骤S11中，在连续多个时隙中第一类型时隙用于sidelink传输的最后一个符号上发送数据。
本公开实施例中，第一终端可以在连续多个时隙中第一类型时隙用于sidelink传输的最后一个符号上发送数据。其中，第一类型时隙为连续多个时隙的非最后一个时隙。
可以如图5所示出的，假设连续多个时隙传输数据为连续4个时隙传输数据。假设第一终端用于发送数据，可以在所有非最后一个时隙中用于sidelink传输的最后一个符号上发送数据。例如，在第一个时隙中用于sidelink传输的最后一个符号上发送数据，在第二个时隙中用于sidelink传输的最后一个符号上发送数据，以及在第三个时隙中用于sidelink传输的最后一个符号上发送数据。可以理解，第一类型时隙中用于sidelink传输的非最后一个符号(可以称为其它符号)通常用于传输相应数据，在本实施例中可以仍然传输相应 数据。
需要说明的是，上述连续多个时隙中第一类型时隙用于sidelink传输的最后一个符号。例如，1个时隙中可以有14个符号，假设序号0-13的符号用于sidelink的传输，则用于sidelink传输的最后一个符号为符号13；或，1个时隙中用于sidelink传输的符号为10个符号，如序号3-12的符号用于sidelink的传输，则用于sidelink传输的最后一个符号为符号12，而不是1个时隙中的最后一个序号为13的符号。因此可以理解，本公开所涉及的最后一个符号可以是相应时隙中用于sidelink传输的最后一个符号。
可以明白的是，相比于相关技术中用于sidelink传输的最后一个符号作为guard symbol的情况，本公开实施例通过在用于sidelink传输的最后一个符号上发送数据，使得用于sidelink传输的最后一个符号无法作为guard symbol，进而第一设备就不会因为guard symbol的存在而进行发收转换，以实现可以连续多个时隙传输数据。
本公开实施例提供的连续多时隙的传输方法，通过在连续多个时隙中非最后一个时隙用于sidelink传输的最后一个符号上发送数据，使得终端可以实现连续多个时隙的数据传输。
本公开实施例提供的一种连续多时隙的传输方法中，图6是根据一示例性实施例示出的另一种连续多时隙的传输方法流程图。如图6所示，在连续多个时隙中第一类型时隙用于sidelink传输的最后一个符号上发送数据，可以包括：
在步骤S21中，在第一类型时隙用于sidelink传输的最后一个符号所在的资源单元(resource element，RE)上进行资源映射，并在第一类型时隙用于sidelink传输的最后一个符号上发送与第一类型时隙用于sidelink传输的最后一个符号相邻的符号和/或非相邻的符号上不同的数据。
本公开实施例中，第一终端可以在第一类型时隙用于sidelink传输的最后一个符号所在的RE上进行资源映射。并在第一类型时隙用于sidelink传输的最后一个符号上发送与第一类型时隙用于sidelink传输的最后一个符号相邻的符号和/或非相邻的符号上不同的数据。其中，相邻的符号表示为第一类型时隙用于sidelink传输的最后一个符号的前一个符号或后一个符号。
例如图7所示出的一种时隙传输示意图，以第N个时隙为例，可以看出，在第N个时隙中，第一终端可以在用于sidelink传输的最后一个符号所在的RE上进行资源映射。第一终端在第N个时隙用于sidelink传输的最后一个符号上发送数据1，该数据1与第N个时隙用于sidelink传输的最后一个符号的前一个符号上的数据2，或后一个符号上的数据3均不同。可以理解，第N个时隙用于sidelink传输的最后一个符号的前一个符号可以是第 N个时隙用于sidelink传输的倒数第二个符号，第N个时隙用于sidelink传输的最后一个符号的后一个符号可以是第N+1个时隙的第一个符号，或者也可以是第N+1个时隙用于sidelink传输的第一个符号。当然，若第N个时隙用于sidelink传输的最后一个符号并非该时隙中的最后一个符号，则第N个时隙用于sidelink传输的最后一个符号的后一个符号可以是紧邻该用于sidelink传输的最后一个符号的后一个符号，例如，1个时隙中可以有14个符号，假设用于sidelink传输的符号为10个符号，如序号3-12的符号。用于sidelink传输的最后一个符号为符号12，则用于sidelink传输的最后一个符号的后一个符号可以是符号13。
在一些情况下，该数据1与第N个时隙的第a个符号上的数据4，或第N+1个时隙的第b个符号上的数据5均不同。可以理解，第a个符号、第b个符号用于表述与第N个时隙用于sidelink传输的最后一个符号非相邻的符号。非相邻的符号可以是除第N个时隙用于sidelink传输的最后一个符号的前一个符号以及后一个符号以外的任意时隙中的任意符号。
也就是说，第一终端可以在第一类型时隙用于sidelink传输的最后一个符号上传输任意有效数据，此有效数据为与其它任意时隙的任意符号不同的数据，即非冗余数据。
本公开实施例中，当第一终端在第一类型时隙用于sidelink传输的最后一个符号上传输有效数据的情况下，可以相应的进行速率匹配，以应对相应资源与实际传输的有效数据不匹配的情况。例如图8所示出的，第一终端需要对第一类型时隙用于sidelink传输的最后一个符号，例如第一个时隙用于sidelink传输的最后一个符号、第二个时隙用于sidelink传输的最后一个符号和第三个时隙用于sidelink传输的最后一个符号进行速率匹配。
或者，在另一些实施例中，图9是根据一示例性实施例示出的又一种连续多时隙的传输方法流程图。如图9所示，在连续多个时隙中第一类型时隙用于sidelink传输的最后一个符号上发送数据，可以包括：
在步骤S31中，在第一类型时隙用于sidelink传输的最后一个符号所在的RE上进行资源映射，并在第一类型时隙用于sidelink传输的最后一个符号上发送与相邻的符号和/或非相邻的符号上相同的数据。
本公开实施例中，第一终端可以在第一类型时隙用于sidelink传输的最后一个符号所在的RE上进行资源映射。并在第一类型时隙用于sidelink传输的最后一个符号上发送与第一类型时隙用于sidelink传输的最后一个符号相邻的符号和/或非相邻的符号上相同的数据。
例如图10所示出的另一种时隙传输示意图，以第N个时隙为例，可以看出，在第N 个时隙中，第一终端可以在用于sidelink传输的最后一个符号所在的RE上进行资源映射。第一终端在第N个时隙用于sidelink传输的最后一个符号上发送数据1，该数据1可以与第N个时隙用于sidelink传输的最后一个符号的前一个符号上的数据1，或后一个符号上的数据1相同。可以理解，第N个时隙用于sidelink传输的最后一个符号的前一个符号可以是第N个时隙用于sidelink传输的倒数第二个符号，第N个时隙的最后一个符号的后一个符号可以是第N+1个时隙的第一个符号，或者也可以是第N+1个时隙用于sidelink传输的第一个符号。当然，若第N个时隙用于sidelink传输的最后一个符号并非该时隙中的最后一个符号，则第N个时隙用于sidelink传输的最后一个符号的后一个符号可以是紧邻该用于sidelink传输的最后一个符号的后一个符号，例如，1个时隙中可以有14个符号，假设用于sidelink传输的符号为10个符号，如序号3-12的符号。用于sidelink传输的最后一个符号为符号12，则用于sidelink传输的最后一个符号的后一个符号可以是符号13。
在一些情况下，该数据1可以与第N个时隙的第a个符号上的数据1，或第N+1个时隙的第b个符号上的数据1相同。可以理解，第a个符号、第b个符号用于表述与第N个时隙用于sidelink传输的最后一个符号非相邻的符号。非相邻的符号可以是除第N个时隙用于sidelink传输的最后一个符号的前一个符号以及后一个符号以外的任意时隙中的任意符号。
也就是说，第一终端可以在第一类型时隙用于sidelink传输的最后一个符号上传输任意冗余数据，此冗余数据为与其它任意时隙的任意符号相同的数据，即非有效数据。
本公开实施例中，在第一类型时隙用于sidelink传输的最后一个符号上传输任意冗余数据的情况下，第一终端也可以进行速率匹配，以避免出现相应资源与实际传输的数据不匹配的情况。
本公开实施例提供的连续多时隙的传输方法，通过在第一类型时隙用于sidelink传输的最后一个符号上传输有效数据或者传输冗余数据，使得最后一个符号无法作为保护符号，进而实现终端连续多个时隙的数据传输。
本公开实施例提供的一种连续多时隙的传输方法中，图11是根据一示例性实施例示出的再一种连续多时隙的传输方法流程图。如图11所示，方法还包括：
在步骤S41中，将连续多个时隙中第二类型时隙用于sidelink传输的最后一个符号作为保护符号，进行第一终端的发收转换。
本公开实施例中，第一终端可以将连续多个时隙中第二类型时隙用于sidelink传输的最后一个符号作为保护符号。其中，第二类型时隙为连续多个时隙的最后一个时隙。第一终端基于连续多个时隙中第二类型时隙的保护符号，进行第一终端的发收转换。
可以如图12所示出的，假设连续多个时隙传输数据为连续4个时隙传输数据。假设第一终端用于发送数据，可以在将最后一个时隙中用于sidelink传输的最后一个符号作为guard symbol。例如，将第四个时隙中用于sidelink传输的最后一个符号作为guard symbol。可以理解，第二类型时隙中用于sidelink传输的非最后一个符号(或称其它符号)通常用于传输相应数据，在本实施例中可以仍然传输相应数据。
可以明白的是，当用于sidelink传输的最后一个符号作为guard symbol的情况下，第一终端可以进行相应的发收转换。
本公开实施例提供的连续多时隙的传输方法，通过将连续多个时隙中最后一个时隙用于sidelink传输的最后一个符号作为保护符号，使得终端可以实现发收转换。
公开实施例提供的一种连续多时隙的传输方法中，图13是根据一示例性实施例示出的另一种连续多时隙的传输方法流程图。如图13所示，方法还包括：
在步骤S51中，发送指示信息。
本公开实施例中，第一终端可以发送指示信息。该指示信息用于指示时隙中是否存在保护符号。其中，若存在保护符号，则保护符号用于第一终端进行发收转换；若不存在保护符号，则指示信息指示的时隙中用于sidelink传输的最后一个符号用于发送数据。
可以理解，第一终端通过发送指示信息，可以使得接收到指示信息的设备了解哪些时隙可能存在保护符号。对于不存在保护符号的时隙，其用于sidelink传输的最后一个符号将用于传输数据。对于存在保护符号的时隙，则相应的终端(例如第一终端或者接收指示信息的终端)可以基于保护符号进行发收转换或者收发转换。
本公开实施例提供的连续多时隙的传输方法，通过指示信息可以指示哪些时隙存在保护符号，哪些时隙不存在保护符号，使得终端可以基于指示信息实现连续多个时隙的数据传输，以及发收转换或收发转换。
本公开实施例提供的一种连续多时隙的传输方法中，指示信息用于指示以下至少一种信息：指示信息用于指示当前时隙是否存在保护符号；指示信息用于指示连续多个时隙的时隙数量。
本公开实施例中，图14是根据一示例性实施例示出的又一种连续多时隙的传输方法流程图。如图14所示，响应于指示信息用于指示当前时隙是否存在保护符号，方法还包括：
在步骤S61中，在连续多个时隙中的各时隙发送指示信息。
本公开实施例中，第一设备发送的指示信息若用于指示当前时隙是否存在保护符号，第一设备可以在连续多个时隙中的每个时隙发送对应时隙的指示信息。以使得指示信息可 以用于指示当前时隙是否存在保护符号。例如，指示信息可以是1比特(bit)信息。如，指示信息为0表示不存在guard symbol，指示信息为1表示存在guard symbol。又或者，指示信息为1表示不存在guard symbol，指示信息为0表示存在guard symbol。本公开对具体指示信息的取值不作限定。
可以理解，当指示信息指示当前时隙不存在保护符号，则表示当前时隙用于sidelink传输的所有符号用于数据传输。当指示信息指示当前时隙存在保护符号，则表示相应终端(例如第一终端或者接收指示信息的终端)应当根据当前时隙的保护符号进行发收转换或者收发转换。
例如图15所示出的一种指示信息发送示意图。假设连续多个时隙传输数据为连续4个时隙传输数据，若指示信息用于指示当前时隙是否存在保护符号。则针对每个时隙可以分别在相应时隙上发送该时隙对应的指示信息。例如，在第一个时隙发送指示信息1，该指示信息1用于指示第一个时隙中是否存在保护符号，也可以认为指示信息1用于指示第一个时隙中用于sidelink传输的最后一个符号是否为保护符号；在第二个时隙发送指示信息2，该指示信息2用于指示第二个时隙中是否存在保护符号，也可以认为指示信息2用于指示第二个时隙中用于sidelink传输的最后一个符号是否为保护符号；在第三个时隙发送指示信息3，该指示信息3用于指示第三个时隙中是否存在保护符号，也可以认为指示信息3用于指示第三个时隙中用于sidelink传输的最后一个符号是否为保护符号；在第四个时隙发送指示信息4，该指示信息4用于指示第四个时隙中是否存在保护符号，也可以认为指示信息4用于指示第四个时隙中用于sidelink传输的最后一个符号是否为保护符号。
本公开实施例中，图16是根据一示例性实施例示出的一种连续多时隙的传输方法流程图。如图16所示，响应于指示信息用于指示连续多个时隙的时隙数量，方法还包括：
在步骤S71中，在连续多个时隙中的第一个时隙或者其它时隙发送指示信息。
本公开实施例中，第一设备发送的指示信息若用于指示连续多个时隙的时隙数量m，其中，m为大于1的正整数。第一设备可以在连续多个时隙中的第一个时隙或者其它时隙发送指示信息。以使得接收到该指示信息的设备可以基于该指示信息确定连续多个时隙的时隙数量，以便相应的终端(例如第一终端或者接收指示信息的终端)在连续多个时隙的最后一个时隙进行发收转换或者收发转换。
例如图17所示出的另一种指示信息发送示意图。假设连续多个时隙传输数据为连续4个时隙传输数据，若指示信息用于指示连续多个时隙的时隙数量m。例如，m＝4。则可以在连续多个时隙中的第一个时隙发送指示信息。例如，在第一个时隙发送指示信息，该指示信息用于指示连续多个时隙的时隙数量m。该指示信息可以表示连续m个时隙中，前 m-1个时隙中用于sidelink传输的最后一个符号不是保护符号，以及第m个时隙中用于sidelink传输的最后一个符号是保护符号。
在一些实施例中，指示信息可以用于指示连续多个时隙的时隙数量m’。该m’表示连续多个时隙中不存在保护符号的时隙数量。假设连续多个时隙传输数据为连续4个时隙传输数据，则m’＝3。仍以图17为例，在第一个时隙发送指示信息，该指示信息用于指示连续多个时隙中不存在保护符号的时隙数量m’。该指示信息可以表示连续m’个时隙中用于sidelink传输的最后一个符号不是保护符号，以及第m’+1个时隙中用于sidelink传输的最后一个符号是保护符号。
又例如图18是根据一示例性实施例示出的又一种指示信息发送示意图。假设连续多个时隙传输数据为连续4个时隙传输数据，若指示信息用于指示连续多个时隙的时隙数量m。例如，m＝4。则可以在连续多个时隙中除第一个时隙以外的其它时隙发送指示信息。例如，在第三个时隙发送指示信息，该指示信息用于指示连续多个时隙的时隙数量m。该指示信息可以表示连续m个时隙中，前m-1个时隙中用于sidelink传输的最后一个符号不是保护符号，以及第m个时隙中用于sidelink传输的最后一个符号是保护符号。
在一些实施例中，指示信息可以用于指示连续多个时隙的时隙数量m’。该m’表示连续多个时隙中不存在保护符号的时隙数量。假设连续多个时隙传输数据为连续4个时隙传输数据，则m’＝3。仍以图18为例，在第三个时隙发送指示信息，该指示信息用于指示连续多个时隙中不存在保护符号的时隙数量m’。该指示信息可以表示连续m’个时隙中用于sidelink传输的最后一个符号不是保护符号，以及第m’+1个时隙中用于sidelink传输的最后一个符号是保护符号。
当指示信息指示连续多个时隙的时隙数量的情况下，可基于连续多个时隙的时隙数量，相应终端(例如第一终端或者接收指示信息的终端)可以在最后一个时隙的保护符号进行发收转换或者收发转换。并在非最后一个时隙用于sidelink传输的所有符号进行数据传输。
可以理解，上述在第三个时隙发送指示信息仅为一种示例性描述，本公开并不限定除第一个时隙以外的其它时隙具体对应的时隙。
在一些实施例中，连续多个时隙的时隙数量可以是预先配置的预配置数值集中的某一个数值，本公开不作限定。
可以明白的是，指示信息用于指示连续多个时隙的时隙数量的情况下，可以认为此类指示信息是一种动态指示方式。
本公开实施例提供的连续多时隙的传输方法，通过不同形式的指示信息对连续多个时 隙中是否存在保护符号进行指示，使得终端可以基于指示信息实现连续多个时隙的数据传输，以及发收转换或收发转换。
本公开实施例提供的一种连续多时隙的传输方法中，指示信息基于第一阶段直连控制信息(sidelink control information，SCI)、第二阶段SCI或媒体访问控制单元(medium access control control element，MAC CE)指示。
本公开实施例中，第一终端可以接收其它终端发送的第一阶段SCI或第二阶段SCI，又或者第一终端接收网络设备发送的MAC CE。第一终端可以基于接收到的第一阶段SCI、第二阶段SCI或MAC CE的指示，确定指示信息。
本公开实施例提供的连续多时隙的传输方法，通过基于第一阶段SCI、第二阶段SCI或MAC CE的指示，确定指示信息，使得终端可以基于指示信息实现连续多个时隙的数据传输，以及发收转换或收发转换。
本公开实施例提供的一种连续多时隙的传输方法中，图19是根据一示例性实施例示出的另一种连续多时隙的传输方法流程图。如图19所示，该方法应用于第一终端，可以包括以下步骤：
在步骤S81中，发送指示信息。
本公开实施例中，第一终端可以发送指示信息。该指示信息用于指示时隙中是否存在保护符号。其中，若存在保护符号，则保护符号用于第一终端进行发收转换；若不存在保护符号，则指示信息指示的时隙中用于sidelink传输的最后一个符号用于发送数据。
在步骤S82中，在连续多个时隙中第一类型时隙用于sidelink传输的最后一个符号上发送数据。
本公开实施例中，第一终端可以在连续多个时隙中第一类型时隙用于sidelink传输的最后一个符号上发送数据。其中，第一类型时隙为连续多个时隙的非最后一个时隙。
可以理解，步骤S81具体实现可以参考步骤S51的实现过程，步骤S82具体实现可以参考步骤S11的实现过程，本公开在此不再赘述。
本公开实施例提供的连续多时隙的传输方法，通过指示信息可以指示哪些时隙存在保护符号，哪些时隙不存在保护符号，使得终端可以基于指示信息在连续多个时隙中非最后一个时隙用于sidelink传输的最后一个符号上发送数据，进而实现连续多个时隙的数据传输。
基于相同构思，图20是根据一示例性实施例示出的又一种连续多时隙的传输方法流程图。如图20所示，该方法用于第二终端，包括以下步骤：
在步骤S91中，在连续多个时隙中第一类型时隙用于sidelink传输的最后一个符号上 接收数据。
本公开实施例中，第二终端可以在连续多个时隙中第一类型时隙用于sidelink传输的最后一个符号上接收数据。其中，第一类型时隙为连续多个时隙的非最后一个时隙。
可以如图5所示出的，假设连续多个时隙传输数据为连续4个时隙传输数据。假设第二终端用于接收数据，可以在所有非最后一个时隙中用于sidelink传输的最后一个符号上接收数据。例如，在第一个时隙中用于sidelink传输的最后一个符号上接收数据，在第二个时隙中用于sidelink传输的最后一个符号上接收数据，以及在第三个时隙中用于sidelink传输的最后一个符号上接收数据。可以理解，第一类型时隙中用于sidelink传输的非最后一个符号(或称其它符号)通常用于传输相应数据，在本实施例中可以仍然传输相应数据。
需要说明的是，上述连续多个时隙中第一类型时隙用于sidelink传输的最后一个符号。例如，1个时隙中可以有14个符号，假设序号0-13的符号用于sidelink的传输，则用于sidelink传输的最后一个符号为符号13；或，1个时隙中用于sidelink传输的符号为10个符号，如序号3-12的符号用于sidelink的传输，则用于sidelink传输的最后一个符号为符号12，而不是1个时隙中的最后一个序号为13的符号。因此可以理解，本公开所涉及的最后一个符号可以是相应时隙中用于sidelink传输的最后一个符号。
可以明白的是，相比于相关技术中用于sidelink传输的最后一个符号作为guard symbol的情况，本公开实施例通过在用于sidelink传输的最后一个符号上接收数据，使得用于sidelink传输的最后一个符号无法作为guard symbol，进而第二设备就不会因为guard symbol的存在而进行收发转换，以实现可以连续多个时隙接收数据。
本公开实施例提供的连续多时隙的传输方法，通过在连续多个时隙中非最后一个时隙用于sidelink传输的最后一个符号上接收数据，使得终端可以实现连续多个时隙的数据传输。
本公开实施例提供的一种连续多时隙的传输方法中，图21是根据一示例性实施例示出的再一种连续多时隙的传输方法流程图。如图21所示，在连续多个时隙中第一类型时隙用于sidelink传输的最后一个符号上接收数据，可以包括：
在步骤S101中，在第一类型时隙用于sidelink传输的最后一个符号上接收与第一类型时隙用于sidelink传输的最后一个符号相邻的符号和/或非相邻的符号上不同的数据。
本公开实施例中，第二终端可以在第一类型时隙用于sidelink传输的最后一个符号上接收与第一类型时隙用于sidelink传输的最后一个符号相邻的符号和/或非相邻的符号上不同的数据。其中，相邻的符号表示为第一类型时隙用于sidelink传输的最后一个符号的前一个符号或后一个符号。
例如图7所示出的一种时隙传输示意图，以第N个时隙为例，可以看出，第二终端在第N个时隙用于sidelink传输的最后一个符号上接收数据1，该数据1与第N个时隙用于sidelink传输的最后一个符号的前一个符号上的数据2，或后一个符号上的数据3均不同。可以理解，第N个时隙用于sidelink传输的最后一个符号的前一个符号可以是第N个时隙用于sidelink传输的倒数第二个符号，第N个时隙用于sidelink传输的最后一个符号的后一个符号可以是第N+1个时隙的第一个符号，或者也可以是第N+1个时隙用于sidelink传输的第一个符号。当然，若第N个时隙用于sidelink传输的最后一个符号并非该时隙中的最后一个符号，则第N个时隙用于sidelink传输的最后一个符号的后一个符号可以是紧邻该用于sidelink传输的最后一个符号的后一个符号，例如，1个时隙中可以有14个符号，假设用于sidelink传输的符号为10个符号，如序号3-12的符号。用于sidelink传输的最后一个符号为符号12，则用于sidelink传输的最后一个符号的后一个符号可以是符号13。
在一些情况下，该数据1与第N个时隙的第a个符号上的数据4，或第N+1个时隙的第b个符号上的数据5均不同。可以理解，第a个符号、第b个符号用于表述与第N个时隙用于sidelink传输的最后一个符号非相邻的符号。非相邻的符号可以是除第N个时隙用于sidelink传输的最后一个符号的前一个符号以及后一个符号以外的任意时隙中的任意符号。
也就是说，第二终端可以在第一类型时隙用于sidelink传输的最后一个符号上接收任意有效数据，此有效数据为与其它任意时隙的任意符号不同的数据，即非冗余数据。
或者，在另一些实施例中，图22是根据一示例性实施例示出的另一种连续多时隙的传输方法流程图。如图22所示，在连续多个时隙中第一类型时隙用于sidelink传输的最后一个符号上接收数据，可以包括：
在步骤S111中，在第一类型时隙用于sidelink传输的最后一个符号上接收与相邻的符号和/或非相邻的符号上相同的数据。
本公开实施例中，第二终端可以在第一类型时隙用于sidelink传输的最后一个符号上接收与第一类型时隙用于sidelink传输的最后一个符号相邻的符号和/或非相邻的符号上相同的数据。
例如图10所示出的另一种时隙传输示意图，以第N个时隙为例，可以看出，第二终端在第N个时隙用于sidelink传输的最后一个符号上接收数据1，该数据1可以与第N个时隙用于sidelink传输的最后一个符号的前一个符号上的数据1，或后一个符号上的数据1相同。可以理解，第N个时隙用于sidelink传输的最后一个符号的前一个符号可以是第N个时隙用于sidelink传输的倒数第二个符号，第N个时隙的最后一个符号的后一个符号可 以是第N+1个时隙的第一个符号，或者也可以是第N+1个时隙用于sidelink传输的第一个符号。当然，若第N个时隙用于sidelink传输的最后一个符号并非该时隙中的最后一个符号，则第N个时隙用于sidelink传输的最后一个符号的后一个符号可以是紧邻该用于sidelink传输的最后一个符号的后一个符号，例如，1个时隙中可以有14个符号，假设用于sidelink传输的符号为10个符号，如序号3-12的符号。用于sidelink传输的最后一个符号为符号12，则用于sidelink传输的最后一个符号的后一个符号可以是符号13。
在一些情况下，该数据1可以与第N个时隙的第a个符号上的数据1，或第N+1个时隙的第b个符号上的数据1相同。可以理解，第a个符号、第b个符号用于表述与第N个时隙用于sidelink传输的最后一个符号非相邻的符号。非相邻的符号可以是除第N个时隙用于sidelink传输的最后一个符号的前一个符号以及后一个符号以外的任意时隙中的任意符号。
也就是说，第二终端可以在第一类型时隙用于sidelink传输的最后一个符号上接收任意冗余数据，此冗余数据为与其它任意时隙的任意符号相同的数据，即非有效数据。
本公开实施例提供的连续多时隙的传输方法，通过在第一类型时隙用于sidelink传输的最后一个符号上接收有效数据或者传输冗余数据，使得最后一个符号无法作为保护符号，进而实现终端连续多个时隙的数据传输。
本公开实施例提供的一种连续多时隙的传输方法中，图23是根据一示例性实施例示出的又一种连续多时隙的传输方法流程图。如图23所示，方法还包括：
在步骤S121中，将连续多个时隙中第二类型时隙用于sidelink传输的最后一个符号作为保护符号，进行第二终端的收发转换。
本公开实施例中，第二终端可以将连续多个时隙中第二类型时隙用于sidelink传输的最后一个符号作为保护符号。其中，第二类型时隙为连续多个时隙的最后一个时隙。第二终端基于连续多个时隙中第二类型时隙的保护符号，进行第二终端的收发转换。
可以如图12所示出的，假设连续多个时隙传输数据为连续4个时隙传输数据。假设第二终端用于接收数据，可以在将最后一个时隙中用于sidelink传输的最后一个符号作为guard symbol。例如，将第四个时隙中用于sidelink传输的最后一个符号作为guard symbol。可以理解，第二类型时隙中用于sidelink传输的非最后一个符号(或称其它符号)通常用于接收相应数据，在本实施例中可以仍然接收相应数据。
可以明白的是，当用于sidelink传输的最后一个符号作为guard symbol的情况下，第二终端可以进行相应的收发转换。
本公开实施例提供的连续多时隙的传输方法，通过将连续多个时隙中最后一个时隙用 于sidelink传输的最后一个符号作为保护符号，使得终端可以实现收发转换。
公开实施例提供的一种连续多时隙的传输方法中，图24是根据一示例性实施例示出的再一种连续多时隙的传输方法流程图。如图24所示，方法还包括：
在步骤S131中，接收指示信息。
本公开实施例中，第二终端可以接收指示信息。该指示信息用于指示时隙中是否存在保护符号。其中，若存在保护符号，则保护符号用于第二终端进行收发转换；若不存在保护符号，则指示信息指示的时隙中用于sidelink传输的最后一个符号用于接收数据。
可以理解，第二终端通过接收指示信息，可以基于该指示信息了解哪些时隙可能存在保护符号。对于不存在保护符号的时隙，其用于sidelink传输的最后一个符号将用于接收数据。对于存在保护符号的时隙，则相应的终端(例如第二终端或者发送指示信息的终端)可以基于保护符号进行收发转换或者发收转换。
本公开实施例中，第二终端可以通过解码指示信息，以确定哪些时隙可能存在保护符号，哪些时隙不存在保护符号。
本公开实施例提供的连续多时隙的传输方法，通过指示信息可以指示哪些时隙存在保护符号，哪些时隙不存在保护符号，使得终端可以基于指示信息实现连续多个时隙的数据传输，以及收发转换或发收转换。
本公开实施例提供的一种连续多时隙的传输方法中，指示信息用于指示以下至少一种信息：指示信息用于指示当前时隙是否存在保护符号；指示信息用于指示连续多个时隙的时隙数量。
本公开实施例中，图25是根据一示例性实施例示出的另一种连续多时隙的传输方法流程图。如图25所示，响应于指示信息用于指示当前时隙是否存在保护符号，方法还包括：
在步骤S141中，在连续多个时隙中的各时隙接收指示信息。
本公开实施例中，第二设备接收的指示信息若用于指示当前时隙是否存在保护符号，第二设备可以在连续多个时隙中的每个时隙接收对应时隙的指示信息。以使得指示信息可以用于指示当前时隙是否存在保护符号。例如，指示信息可以是1比特(bit)信息。如，指示信息为0表示不存在guard symbol，指示信息为1表示存在guard symbol。又或者，指示信息为1表示不存在guard symbol，指示信息为0表示存在guard symbol。本公开对具体指示信息的取值不作限定。
可以理解，当指示信息指示当前时隙不存在保护符号，则表示当前时隙用于sidelink传输的所有符号用于数据传输。当指示信息指示当前时隙存在保护符号，则表示相应终端 (例如第二终端或者发送指示信息的终端)应当根据当前时隙的保护符号进行收发转换或者发收转换。
例如图15所示，假设连续多个时隙传输数据为连续4个时隙传输数据，若指示信息用于指示当前时隙是否存在保护符号。则针对每个时隙可以分别在相应时隙上接收该时隙对应的指示信息。例如，在第一个时隙接收指示信息1，该指示信息1用于指示第一个时隙中是否存在保护符号，也可以认为指示信息1用于指示第一个时隙中用于sidelink传输的最后一个符号是否为保护符号；在第二个时隙接收指示信息2，该指示信息2用于指示第二个时隙中是否存在保护符号，也可以认为指示信息2用于指示第二个时隙中用于sidelink传输的最后一个符号是否为保护符号；在第三个时隙接收指示信息3，该指示信息3用于指示第三个时隙中是否存在保护符号，也可以认为指示信息3用于指示第三个时隙中用于sidelink传输的最后一个符号是否为保护符号；在第四个时隙接收指示信息4，该指示信息4用于指示第四个时隙中是否存在保护符号，也可以认为指示信息4用于指示第四个时隙中用于sidelink传输的最后一个符号是否为保护符号。
本公开实施例中，第二终端可以通过解码每个时隙对应的指示信息，以确定当前时隙是否存在保护符号。
本公开实施例中，图26是根据一示例性实施例示出的又一种连续多时隙的传输方法流程图。如图26所示，响应于指示信息用于指示连续多个时隙的时隙数量，方法还包括：
在步骤S151中，在连续多个时隙中的第一个时隙或者其它时隙接收指示信息。
本公开实施例中，第二设备发送的指示信息若用于指示连续多个时隙的时隙数量m，其中，m为大于1的正整数。第二设备可以在连续多个时隙中的第一个时隙或者其它时隙接收指示信息。以便第二设备可以基于该指示信息确定连续多个时隙的时隙数量，相应的终端(例如第二终端或者发送指示信息的终端)在连续多个时隙的最后一个时隙进行收发转换或者发收转换。
例如图17所示，假设连续多个时隙传输数据为连续4个时隙传输数据，若指示信息用于指示连续多个时隙的时隙数量m。例如，m＝4。则可以在连续多个时隙中的第一个时隙接收指示信息。例如，在第一个时隙接收指示信息，该指示信息用于指示连续多个时隙的时隙数量m。该指示信息可以表示连续m个时隙中，前m-1个时隙中用于sidelink传输的最后一个符号不是保护符号，以及第m个时隙中用于sidelink传输的最后一个符号是保护符号。
在一些实施例中，指示信息可以用于指示连续多个时隙的时隙数量m’。该m’表示连续多个时隙中不存在保护符号的时隙数量。假设连续多个时隙传输数据为连续4个时隙 传输数据，则m’＝3。仍以图17为例，在第一个时隙接收指示信息，该指示信息用于指示连续多个时隙中不存在保护符号的时隙数量m’。该指示信息可以表示连续m’个时隙中用于sidelink传输的最后一个符号不是保护符号，以及第m’+1个时隙中用于sidelink传输的最后一个符号是保护符号。
又例如图18所示，假设连续多个时隙传输数据为连续4个时隙传输数据，若指示信息用于指示连续多个时隙的时隙数量m。例如，m＝4。则可以在连续多个时隙中除第一个时隙以外的其它时隙接收指示信息。例如，在第三个时隙接收指示信息，该指示信息用于指示连续多个时隙的时隙数量m。该指示信息可以表示连续m个时隙中，前m-1个时隙中用于sidelink传输的最后一个符号不是保护符号，以及第m个时隙中用于sidelink传输的最后一个符号是保护符号。
在一些实施例中，指示信息可以用于指示连续多个时隙的时隙数量m’。该m’表示连续多个时隙中不存在保护符号的时隙数量。假设连续多个时隙传输数据为连续4个时隙传输数据，则m’＝3。仍以图18为例，在第三个时隙接收指示信息，该指示信息用于指示连续多个时隙中不存在保护符号的时隙数量m’。该指示信息可以表示连续m’个时隙中用于sidelink传输的最后一个符号不是保护符号，以及第m’+1个时隙中用于sidelink传输的最后一个符号是保护符号。
本公开实施例中，第二终端可以通过解码第一个时隙或其它时隙接收到的指示信息，以确定连续多个时隙中哪些时隙存在保护符号，哪些时隙不存在保护符号。
当指示信息指示连续多个时隙的时隙数量的情况下，可基于连续多个时隙的时隙数量，相应终端(例如第二终端或者发送指示信息的终端)可以在最后一个时隙的保护符号进行收发转换或者发收转换。并在非最后一个时隙用于sidelink传输的所有符号进行数据接收。
可以理解，上述在第三个时隙接收指示信息仅为一种示例性描述，本公开并不限定除第一个时隙以外的其它时隙具体对应的时隙。
在一些实施例中，连续多个时隙的时隙数量可以是预先配置的预配置数值集中的某一个数值，本公开不作限定。
可以明白的是，指示信息用于指示连续多个时隙的时隙数量的情况下，可以认为此类指示信息是一种动态指示方式。

本公开实施例中，第二终端可以接收其它终端发送的第一阶段SCI或第二阶段SCI，又或者第一终端接收网络设备发送的MAC CE。第二终端可以基于接收到的第一阶段SCI、第二阶段SCI或MAC CE的指示，确定指示信息。
本公开实施例提供的连续多时隙的传输方法，通过基于第一阶段SCI、第二阶段SCI或MAC CE的指示，确定指示信息，使得终端可以基于指示信息实现连续多个时隙的数据接收，以及收发转换或发收转换。
本公开实施例提供的一种连续多时隙的传输方法中，图27是根据一示例性实施例示出的再一种连续多时隙的传输方法流程图。如图27所示，该方法应用与第二终端，可以包括以下步骤：
在步骤S161中，接收指示信息。
本公开实施例中，第二终端可以接收指示信息。该指示信息用于指示时隙中是否存在保护符号。其中，若存在保护符号，则保护符号用于第二终端进行收发转换；若不存在保护符号，则指示信息指示的时隙中用于sidelink传输的最后一个符号用于接收数据。
在步骤S162中，在连续多个时隙中第一类型时隙用于sidelink传输的最后一个符号上接收数据。
本公开实施例中，第二终端可以在连续多个时隙中第一类型时隙用于sidelink传输的最后一个符号上接收数据。其中，第一类型时隙为连续多个时隙的非最后一个时隙。
可以理解，步骤S161具体实现可以参考步骤S131的实现过程，步骤S162具体实现可以参考步骤S91的实现过程，本公开在此不再赘述。
本公开实施例提供的连续多时隙的传输方法，通过指示信息可以指示哪些时隙存在保护符号，哪些时隙不存在保护符号，使得终端可以基于指示信息在连续多个时隙中非最后一个时隙用于sidelink传输的最后一个符号上接收数据，进而实现连续多个时隙的数据传输。
本公开实施例提供的一种连续多时隙的传输方法中，图28是根据一示例性实施例示出的一种连续多时隙传输示意图。
本公开实施例中，如图28所示，假设连续多个时隙传输数据为连续4个时隙传输数据。其中，第一个时隙中用于sidelink传输的最后一个符号用于传输数据，在第二个时隙中用于sidelink传输的最后一个符号用于传输数据，以及在第三个时隙中用于sidelink传输的最后一个符号用于传输数据。可以理解，对于某个时隙中用于sidelink传输的最后一个 符号用于传输数据，可以响应于终端为第一终端的情况下发送数据，或者可以响应于终端为第二终端的情况下接收数据。第四个时隙中用于sidelink传输的最后一个符号可以作为GP。
在终端为第一终端的情况下，第一终端需要在第一个时隙、第二个时隙以及在第三个时隙中用于sidelink传输的的最后一个符号上发送数据。因此可能会出现相应符号对应的资源和需要发送的数据不匹配的情况。第一终端可以对第一个时隙用于sidelink传输的最后一个符号、第二个时隙用于sidelink传输的最后一个符号和第三个时隙用于sidelink传输的最后一个符号以及相应需要传输的数据进行速率匹配。而对于第四个时隙用于sidelink传输的最后一个符号，由于该符号作为GP，则无需进行速率匹配。
本公开实施例中，第一终端发送的数据可以是物理直连链路共享信道(physical sidelink shared channel，PSSCH)上传输的数据。

本公开实施例提供的一种连续多时隙的传输方法中，图29是根据一示例性实施例示出的另一种连续多时隙传输示意图。
本公开实施例中，如图29所示，假设连续多个时隙传输数据为连续4个时隙传输数据。其中，第一个时隙中用于sidelink传输的最后一个符号用于传输数据，在第二个时隙中用于sidelink传输的最后一个符号用于传输数据，以及在第三个时隙中用于sidelink传输的最后一个符号用于传输数据。可以理解，对于某个时隙中用于sidelink传输的最后一个符号用于传输数据，可以响应于终端为第一终端的情况下发送数据，或者可以响应于终端为第二终端的情况下接收数据。第四个时隙中用于sidelink传输的最后一个符号可以作为GP。
在第一类时隙中用于sidelink传输的最后一个符号上传输数据，可以传输与当前最后一个符号相邻的符号上不同的数据，即可以认为是传输有效数据，或称非冗余数据。例如图29中，第一个时隙中用于sidelink传输的最后一个符号用于传输数据1，该数据1与相邻的符号的数据2、数据3均不相同。同理，第二个时隙中用于sidelink传输的最后一个符号用于传输数据4，该数据4与相邻的符号的数据5、数据6均不相同。第三个时隙中用于sidelink传输的最后一个符号用于传输数据7，该数据7与相邻的符号的数据8、数据9均不相同。

在第一类时隙中用于sidelink传输的最后一个符号上传输数据，可以传输与当前最后一个符号非相邻的符号上不同的数据，即可以认为是传输有效数据，或称非冗余数据。例如图30中，第一个时隙中用于sidelink传输的最后一个符号用于传输数据1，该数据1与非相邻的符号的例如第a个符号的数据2、第b个符号的数据3不同。同理，第二个时隙中用于sidelink传输的最后一个符号用于传输数据4，该数据4与非相邻的符号的例如第b个符号的数据3、第c个符号的数据5不同。第三个时隙中用于sidelink传输的最后一个符号用于传输数据7，该数据7与非相邻的符号的例如第c个符号的数据5、第d个符号的数据8不同。

在第一类时隙中用于sidelink传输的最后一个符号上传输数据，可以传输与当前最后一个符号相邻的符号上相同的数据，即可以认为是传输冗余数据，或称非有效数据。可以理解，相邻的符号可以是当前最后一个符号的前一个符号或后一个符号。例如图31中，第一个时隙中用于sidelink传输的最后一个符号用于传输数据1，该数据1与前一个符号的数据1或后一个符号的数据1相同。同理，第二个时隙中用于sidelink传输的最后一个符号用于传输数据2，该数据2与前一个符号的数据2或后一个符号的数据2相同。第三个时隙中用于sidelink传输的最后一个符号用于传输数据3，该数据3与前一个符号的数据3或后一个符号的数据3相同。
