Idle detection of each 9 ⁇ s time slot follows the same rules as previously described, i.e. the received energy is below the threshold.

Description

处理方法、通信设备及存储介质 技术领域
本申请涉及通信技术领域，具体涉及一种处理方法、通信设备及存储介质。
背景技术
一些实现中，随着无线通信技术的发展，人们对高数据速率和用户体验的需求日益增长，同时人们对了解周边人或事物并与之通信的邻近服务的需求逐渐增加，因此设备到设备(英文全称为：device-to-device，英文简称为：D2D)技术应运而生。Sidelink(英文简称为SL，中文为侧链路)通信技术是实现D2D技术的重要部分，目前，Sidelink上设定的所有时隙都是半静态配置而成。
在构思及实现本申请过程中，发明人发现至少存在如下问题：半静态配置时隙格式意味着发送终端和接收终端的收发时隙是固定的，当应用到非授权频谱上时，一个COT(英文全称为：Channel Occupied Time，中文为：信道占据时间)内会存在多次收发切换点，这将导致发送终端和接收终端需要进行多次LBT(英文全称为：listen before talk，中文为：先听后发)，丢失信道的概率较高。
前面的叙述在于提供一般的背景信息，并不一定构成现有技术。

为了便于理解本申请实施例，下面对本申请的终端设备所基于的通信网络系统进行描述。

虽然上述以LTE系统为例进行了介绍，但本领域技术人员应当知晓，本申请不仅仅适用于LTE系统，也可以适用于其他无线通信系统，例如GSM、CDMA2000、WCDMA、TD-SCDMA以及未来新的网络系统(如5G)等，此处不做限定。
下面对本发明实施例提供的处理方法的应用场景进行介绍。如图2所示，UE201可以作为发射终端或接收终端，E-UTRAN202可以作为网络侧。当UE201为多个时，各UE之间可以建立侧链路连接。E-UTRAN202可以针对UE201在使用的非授权频谱进行对应的无线资源控制，以确定或生成无线资源控制信令，该无线资源控制信令用以指示侧链路时隙周期内应用于第一时隙的静态时隙格式。作为发射终端的UE可以向接收终端发送控制信息，该控制信息用于指示侧链路时隙周期内应用于第二时隙的灵活时隙格式，从而完成对侧链路时隙周期的配置，以进行后续的数据传输。
基于上述终端设备硬件结构以及通信网络系统，提出本申请各个实施例。
在一些实现中，随着无线通信技术的发展，侧链路通信技术可以应用在授权频谱和非授权频谱上。与应用到授权频谱时相同，在侧链路通信技术应用到非授权频谱上时，所有的时隙都由半静态配置而成，半静态配置时隙格式意味着发送终端和接收终端的收发时隙是固定的，一个信道占据时间内存在多次收发切换点。授权频谱由于各通信设备有序占用信道，因而，不会丢失信道。而非授权频谱上各通信设备处于竞争信道的情况，当前占用信道的通信设备若处于收发切换点，较容易由于其他通信设备对信道的抢占而导致丢失信道。因而，目前侧链路在非授权频谱上由于所有时隙由半静态配置而成，导致丢失信道的概率较高。
针对上述丢失信道的概率较高的问题，发明人在研究中发现，为了解决该问题，可以对侧链路中的时隙进行动态配置。更进一步的，进行动态配置时首先需要确定动态配置的主体，是仅依靠网络侧设备比如基站进行配置，还是通过结合网络侧设备和终端设备进行配置。发明人在研究中发现，由于通信网络中，每个网络侧设备可能对应数量较多的终端设备，仅依靠网络侧设备进行配置，配置的时隙格式与终端设备需求的时隙格式可能存在不匹配的情况。因而，可以采用结合网络侧设备和发射终端来进行配置的方式，即由网络侧设备的无线资源控制信令对时隙配置静态时隙格式，发射终端确定或生成的控制信息对时隙配置灵活时隙格式，使收发时隙可以灵活分布，减少收发切换点，从而降低丢失信道的概率。
发明人基于上述的创造性发现，提出了本申请的技术方案。
下面，通过具体实施例对本申请所示的技术方案进行详细说明。可选地，如下实施例可以单独存在，也可以相互结合，对于相同或相似的内容，在不同的实施例中不再重复说明。
图3为本申请实施例提供的处理方法的流程示意图一，本实施例以执行本处理方法的主体为终端设备(如UE)为例进行示例说明，当终端设备作为发射终端处理相关任务时，如图3所示，该方法包括：
S11，接收无线资源控制信令，无线资源控制信令用于指示侧链路时隙周期内应用于第一时隙的静态时隙格式。
无线资源控制(英文全称为：Radio Resource Control，英文简称为：RRC)信令，可以由网络侧设备比如基站生成并发送，无线资源控制信令一般配置有频率资源、时间资源、码资源、功率资源和/或空间资源等相关信息，可以指示终端设备使用无线网络资源。
侧链路时隙周期一般包括至少一个时隙，每个时隙按照时隙格式的不同，可以传输和/或接收不同的信道/数据，例如其中一个时隙可以传输物理数据信道和/或物理控制信道，其中另一个时隙可以接收物理反馈信道，其中另一个时隙可以传输同步信息块等。可选地，在确定时隙格式后，终端设备需按照时隙格式在该时隙传输和/或接收对应信道。
第一时隙可以为侧链路时隙周期的所有时隙，第一时隙对应的静态时隙格式可以为指示在第一时隙传输和/或接收侧链路物理控制信道、侧链路物理数据信道、侧链路物理反馈信道、侧链路同步信道或者指示第一时隙为灵活时隙至少一项。
一种可能的实现方式中，假设侧链路时隙周期包括10个时隙，该10个时隙为第一时隙。在配置时对应的时隙格式为：7个时隙对应传输侧链路物理控制信道和/或侧链路物理数据信道，2个时隙对应为灵活时隙，1个时隙对应为传输侧链路同步信道。被指示为对应传输侧链路物理控制信道和/或侧链路物理数据信道、传输侧链路同步信道的时隙格式是固定的，发射终端不能调整其时隙格式。而被指示为灵活时隙的时隙，可以由发射终端根据数据传输任务来确定，灵活时隙可以被指示为以下至少一项：
传输或者接收侧链路物理控制信道和/或侧链路物理数据信道，接收或者传输侧链路物理反馈信道，传输或者接收侧链路同步信息块。
S12，向接收终端发送控制信息，控制信息用于指示侧链路时隙周期内应用于第二时隙的灵活时隙格式。
第二时隙可以为第一时隙中被指示为灵活时隙的时隙，第二时隙对应的灵活时隙格式可以用于指示在第二时隙传输和/或接收以下至少一项：
侧链路物理控制信道，侧链路物理数据信道，侧链路物理反馈信道，侧链路同步信息块。可选地，侧链路物理反馈信道由接收终端传输。
在相同非授权频谱上占用无线资源的终端设备都会接收到无线资源控制信令，因而，控制信息可以仅指示侧链路时隙周期内应用于第二时隙的灵活时隙格式，以使接收终端知晓侧链路时隙周期中灵活时隙对应的灵活时隙格式，为后续传输数据提供基础。
可选地，为了进一步提高数据传输的稳定性，控制信息还可以用于指示侧链路时隙周期内应用于第一时隙的静态时隙格式，从而避免接收终端由于网络质量等因素未接收到无线资源控制信令的情况。
可选地，控制信息可以为侧链路控制信息，侧链路控制信息通过侧链路物理控制信道 和/或侧链路物理数据信道传输。
可选地，侧链路控制信息作为公共侧链路控制信息通过侧链路物理控制信道传输。
可选地，控制信息可以为侧链路无线资源控制信令或侧链路控制信息，以降低物理层控制信息的开销。
NR(英文全称为New Radio)Sidelink传输与NR下行传输类似，都是基于传统的OFDM(英文全称为：Orthogonal Frequency Division Multiplexing，中文为：正交频分复用技术)。当一个终端设备进行Sidelink传输时，会给终端配置一个Sidelink资源池，资源池定义了一个载波上可用于Sidelink通信的全部时间/频率资源。可选地，在时域上资源池为一个时隙集合，按照资源池周期重复。在频域上，资源池为一个连续的子信道集合，每个子信道由一些连续的资源块组成。
尽管资源池的配置在时域是以时隙为粒度，但并不意味着一个Sidelink时隙的所有符号都要用于Sidelink传输。网络可以加以限制，使得一个Sidelink时隙内连续符号的有限集真正可以用于Sidelink通信，可以通过下面的配置来实现：
可用于Sidelink通信的连续符号集的第一个符号，范围在符号0到符号7之间。
可用于Sidelink通信的连续符号数，范围在7～14个符号。
通过这种方式，可以在Sidelink通信和传统的上下行通信共享一个载波时确保一个时隙第一个和/或最后几个符号可用于上行或下行控制信令。
在Sidelink有特定载波或者在非授权载波上的情况下，通常假定一个Sidelink时隙里的所有符号都可用于Sidelink通信。
因而，本实施例中的灵活时隙格式有至少一种。为了进一步详细说明灵活时隙格式，下面将结合图4a-图4f进行说明。图中，AGC(英文全称为：Automatic Gain Control，中文为：自动增益控制)指自动增益控制符号。

灵活时隙格式可以为：
第一时隙格式，第一时隙格式用于指示第二时隙对应传输侧链路物理控制信道和/或侧链路物理数据信道。该时隙格式可以用于指示在该灵活时隙发射终端传输物理数据和/或控制信息。
第二时隙格式，第二时隙格式用于指示在第二时隙传输侧链路物理控制信道和/或侧链路物理数据信道，以及接收终端传输侧链路物理反馈信道。该时隙格式可以用于指示在该灵活时隙发射终端传输物理数据和/或控制信息，以及接收终端传输反馈信息。
反馈信息可以包括HARQ(英文全称为：Hybrid Automatic Repeat reQuest，中文为：混合自动重传请求)反馈和/或信道质量反馈等。
第三时隙格式，第三时隙格式用于指示第二时隙接收终端对应传输侧链路物理反馈信道。该时隙格式仅用于指示该灵活时隙接收终端传输反馈信息。
第四时隙格式，第四时隙格式用于指示第二时隙对应传输侧链路同步信息块。该时隙格式仅用于指示该灵活时隙发射终端传输侧链路同步信息块，以实现时间上的同步。
可选地，第一时隙格式如图4b所示，第一时隙格式中第一个符号为自动增益控制符号，和/或，也可以用于承载侧链路物理控制信道和/或侧链路数据信道的一部分，最后一个符号为第一保护符号，第一个符号与最后一个符号之间的符号用于传输侧链路物理控制 信道和/或侧链路数据信道。
第二时隙格式中第一个符号为自动增益控制符号，和/或，也可以用于承载侧链路物理控制信道和/或侧链路数据信道的一部分，第一个符号之后的至少一个符号用于传输侧链路物理控制信道和/或侧链路数据信道，至少一个符号之后的符号为第二保护符号，最后一个符号为第一保护符号，第一保护符号与第二保护符号之间的符号用于传输侧链路物理反馈信道。
第二时隙格式可以按照实际需求来设置用于传输侧链路物理控制信道和/或侧链路数据信道的符号数量以及用于传输侧链路物理反馈信道符号的数量。
若静态时隙格式中传输侧链路物理控制信道和/或侧链路数据信道的时隙数量较多，可以将传输侧链路物理反馈信道符号的数量设置为至少两个，从而满足接收终端需要反馈多于2比特的反馈信息的需求。
若其他灵活时隙的灵活时隙格式中传输侧链路物理控制信道和/或侧链路数据信道的符号数量较多，则当前灵活时隙的灵活时隙格式可以增加传输侧链路物理反馈信道符号的数量。
在一种可能的实现方式中，如图4c所示，用于传输侧链路物理控制信道和/或侧链路数据信道的符号数量为9个，用于传输侧链路物理反馈信道符号的数量为2个。
在一种可能的实现方式中，如图4d所示，用于传输侧链路物理控制信道和/或侧链路数据信道的符号数量为5个，用于传输侧链路物理反馈信道符号的数量为6个。
第三时隙格式中，如图4e所示，第一个符号为自动增益控制符号，和/或，也可以用于承载侧链路物理反馈信道的一部分，最后一个符号为第一保护符号，第一个符号与最后一个符号之间的符号用于传输侧链路物理反馈信道。
第四时隙格式中，如图4a所示，第一个符号为自动增益控制符号，和/或，也可以用于承载侧链路广播信道及对应的解调参考信号的一部分，第二和第三个符号用于传输侧链路主同步序列，第四和第五个符号用于传输侧链路辅同步序列，第六至第十三个符号用于传输侧链路广播信道，最后一个符号为第一保护符号。第四时隙格式用于传输同步相关信息。
可选地，第一保护符号和第二保护符号上不承载信道和/或信号。
可选地，控制信息中可以包括指示灵活时隙格式的信息，比如可以采用比特域中包含的至少一个比特块来进行指示。比特块的数值与灵活时隙格式具有映射关系，从而使比特块的不同取值对应不同的灵活时隙格式。
在一种可能的实现方式中，比特块数值为1时对应第一时隙格式，数值为2时对应第二时隙格式，数值为3时对应第三时隙格式，数值为4时对应第四时隙格式。
又比如，可以采用预设表格，通过预先构建比特块的数值与预设表格中存储的灵活时隙格式之间的映射关系来指示灵活时隙格式。预设表格可以由无线资源控制信令进行配置。
在一种可能的实现方式中，比特块数值为5时对应表格中第一时隙格式，数值为6时对应表格中第二时隙格式，数值为7时对应表格中第三时隙格式，数值为8时对应表格第四时隙格式。
在一种可能的实现方式中，比特域中的至少一个比特块对应一个时隙周期内的一个时隙。
在一种可能的实现方式中，如图4f所示，侧链路时隙周期为10个时隙，无线资源控制信令配置的静态时隙格式为：
第1-3，第5-7以及第8时隙即图中为数字1的时隙被配置为传输侧链路物理控制信道和/或侧链路物理数据信道。
第4和第8时隙即图中为X的时隙被配置为灵活时隙，灵活时隙需发射终端进一步配置具体时隙格式。
最后的时隙即图中为数字0的时隙被配置为传输侧链路同步信息块。
在本实现方式中，如图4f所示，第4时隙由发射终端配置为第一时隙格式，第8时隙由发射终端配置为第二时隙格式，且用于传输侧链路物理反馈信道符号的数量为7个，以满足整个侧链路时隙周期内对反馈信息的需求，还可以降低收发切换点的数量，降低信道丢失概率。若采用现有技术中的半静态配置方式，需要采用更多的时隙来配置传输侧链 路物理反馈信道符号，且每个时隙传输侧链路物理反馈信道符号数量固定，从而形成更多的收发切换点，信道丢失概率较高。
为了进一步提高发射终端与接收终端之间传输的稳定性，可以增加侧链路控制信息的发送次数，也可以在接收终端由于网络状况等原因未接收到指示灵活时隙格式的控制信息时，预先设置灵活时隙对应的灵活时隙格式。
比如，在一般情况下，可以预先设置为第二时隙格式或第三时隙格式，以满足反馈信息传输的需求。也可以按照实际需求预先设置为第一时隙格式和/或第四时隙格式等，本实施例对此不作限定。
在一种可能的实现方式中，控制信息中可以包括指示灵活时隙格式的信息，后续收到的控制信息可以修改之前收到的所述控制信息所指示的灵活时隙格式。
图5为本申请实施例提供的信道传输流程示意图，如图5所示，当接收终端数量不同时，可以按照数量进行对应处理，具体如下：
S21，确定接收终端的数量。
S22，若接收终端为一个，则侧链路控制信息通过侧链路物理控制信道和/或侧链路物理数据信道传输。
当接收终端为一个时，可以通过侧链路物理控制信道和/或侧链路物理数据信道传输侧链路控制信息。若通过侧链路物理控制信道传输侧链路控制信息，其他终端设备可以通过监听知晓信道已被占用。若通过侧链路物理数据信道传输侧链路控制信息，其他终端设备不能通过监听知晓信道占用情况。因而，可以根据实际情况进行选择，本实施例对此不作限定。
和/或，S23，若接收终端为多个，则侧链路控制信息作为公共侧链路控制信息通过侧链路物理控制信道传输。
当接收终端为多个时，可以将侧链路控制信息作为公共侧链路控制信息通过侧链路物理控制信道传输，以提高传输效率。可选地，公共侧链路控制信息的大小可以与现有侧链路控制信息的大小设为一致，从而使侧链路控制信息的盲解复杂度与现有侧链路控制信息的盲解复杂度相近，进一步提高传输效率。
图6为本申请实施例提供的信道占据流程示意图，如图6所示，在非授权频谱中，由于终端之间相互抢占信道，在发射终端抢占到信道后，需要确定如何在信道占据时间内进行数据传输，具体如下：
S31，进行第一先听后发操作，以确定信道占据时间。
发射终端在进行第一先听后发操作时，可以监听到信道是否可以被占用，以及确定信道占据时间。信道占据时间存在预设的上限，因而，确定出的信道占据时间不能超过预设的上限时间。
可选地，第一先听后发操作为信道接入流程类型1。信道接入流程类型1用于在同一COT内发起一个或者多个传输。通过执行随机退避的LBT流程来评估信道是否可用。首先，发射终端监听信道并等待，直到某信道至少在被称为延迟周期的一段时间内可用为止。延迟周期由一个16μs(时间单位微秒)加若干个9μs时隙组成，延迟周期的长度取决于优先级类别。如果每个9μs时隙中至少有4μs时间内的接收能量低于阈值，则说明信道可用。一旦信道(至少)在延迟周期内被确认可用，发射机就启动随机退避操作，即等待一段随机的时间。退避过程首先在竞争窗口(英文全称为：Contention Window，英文简称为：CW)内用一个随机数初始化退避计数器。该随机数来自均匀分布[0，CW]，以9μs的倍数表示传输前信道必须保持可用的持续时间。如果信道在每个9μs时隙被检测到空闲，则退避计数器减1；反之，每当信道被检测到繁忙时，则退避计数器保持不变，直到信道空闲时间达到延迟周期。每个9μs时隙的空闲检测遵循与前面描述的相同规则，即接收能量低于阈值。一旦退避计数器归零，随机退避过程就完成了，此时发射机已经获得信道，并且可以使用信道进行传输，直到达到该优先级类别所对应的最大信道占用时间。
S32，判断信道占据时间是否与同步时隙发生重叠。若是，则执行S33，和/或，若否，则执行S35。
同步时隙为通过侧链路同步信道传输同步信息的第一时隙，同步时隙传输同步信息是侧链路时隙周期中必须执行的过程。
每次信道占据时间的起始时间与结束时间是不同的，信道占据时间内可能会存在与同步时隙发生重叠的情况，也可能不存在与同步时隙发生重叠的情况。当信道占据时间与同步时隙发生重叠时，根据发射终端的处理方式的不同，会影响信道占据时间的长短。
S33，判断是否在同步时隙传输同步信息。
S34，根据是否在同步时隙传输同步信息的结果确定信道占据时间的结束时间。
可选地，若确定在同步时隙传输同步信息，则在传输同步信息后，进行第二先听后发操作，以确定信道是否在传输同步信息后继续占据。此次进行的第二先听后发操作相比第一先听后发操作的监听时间更短，执行整体时间更短，从而可以降低发射终端在同步时隙传输同步信息后的衔接时间，提高传输效率。
可选地，若确定信道可在传输同步信息后继续占据，则确定信道占据时间的结束时间为信道占据时间的原始结束时间，和/或，若确定信道不可在传输同步信息后继续占据，则确定信道占据时间的结束时间为同步时隙。
可选地，在确定可以继续占据后，发射终端将按照侧链路时隙周期以及对应的时隙格式进行数据传输。在确定不可在传输同步信息后继续占据时，信道占据时间在同步时隙时已经结束，将由其他占用信道的终端进行后续数据传输。
可选地，若确定不在同步时隙传输同步信息，则信道占据时间的结束时间为同步时隙的前一时隙。
可选地，若发射终端不在同步时隙传输同步信息，此时，发射终端仅能在同步时隙的前一时隙占用信道，而在同步时隙时，不能继续占用信道，因而，信道占据时间的结束时间为同步时隙的前一时隙。
可选地，第二先听后发操作为信道接入流程类型2。根据COT中间传输间隙的持续时间，信道类型2可以有三种子类型：
类型2A，当两次传输之间的间隙为25μs时使用；
类型2B，当两次传输之间的间隙为16μs时使用；
类型2C，当两次传输之间的间隙小于16μs时使用；
类型2A和类型2B可以被视为没有随机退避的类型1，如果检测到信道空闲，就申明其可用，如果检测到信道繁忙，就说明无法使用COT。如果在上一次传输之后的16μs之内发生下一次传输，则在传输突发之间不需要进行信道空闲检测，这称为信道接入流程2C。
S35，确定信道占据时间的结束时间为信道占据时间的原始结束时间。
在信道占据时间未与同步时隙发生重叠时，信道占据时间将在原始结束时间结束，不会受到同步时隙的影响。
图7为本申请实施例提供的处理方法的流程示意图二，本实施例以执行本处理方法的主体为终端设备(如UE)为例进行示例说明，当终端设备作为发射终端处理相关任务时，可以根据实际应用场景，如接收终端的数量进行对应流程处理，如图7所示，该方法包括：
S41，响应于向接收终端发送控制信息，根据接收终端的数量向接收终端发送控制信息。
发射终端可以是响应于当前数据传输任务、无线资源控制信令等，然后向接收终端发送控制信息以使接收终端知晓进行数据传输的相关信息。可选地，相关信息可以包括时间、数据、传输方式等。
在进行侧链路传输时，可以由一个发射终端对应一个接收终端，也可以由一个发射终端对应多个接收终端，因而，可以根据接收终端的数量向接收终端发送控制信息。
具体如图8所示，方法包括：
S51，响应于向接收终端发送控制信息。
S52，若接收终端的数量为一个，则通过侧链路物理控制信道或侧链路物理数据信道发送控制信息。
当接收终端为一个时，可以通过侧链路物理控制信道或侧链路物理数据信道传输控制信息。若通过侧链路物理控制信道传输控制信息，其他终端设备可以通过监听知晓信道已 被占用。若通过侧链路物理数据信道传输控制信息，其他终端设备不能通过监听知晓信道占用情况。因而，可以根据实际情况进行选择，本实施例对此不作限定。
和/或，S53，若接收终端的数量为多个，则控制信息作为公共侧链路控制信息通过侧链路物理控制信道传输。
当接收终端为多个时，可以将控制信息作为公共侧链路控制信息通过侧链路物理控制信道传输，以提高传输效率。可选地，公共侧链路控制信息的大小可以与现有控制信息的大小设为一致，从而使控制信息的盲解复杂度将与现有控制信息的盲解复杂度相近，进一步提高传输效率。
可选地，在应用于非授权频谱时，发射终端可以接收用于指示侧链路时隙周期内应用于第一时隙的静态时隙格式的无线资源控制信令。
控制信息可以用于指示侧链路时隙周期内应用于第二时隙的灵活时隙格式。
无线资源控制信令，可以由网络侧设备比如基站生成并发送，无线资源控制信令一般配置有频率资源、时间资源、码资源、功率资源和/或空间资源等相关信息，可以指示终端设备使用无线网络资源。
侧链路时隙周期一般包括至少一个时隙，每个时隙按照时隙格式的不同，可以传输和/或接收不同的信道/数据，例如其中一个时隙可以传输物理信道和/或物理控制信道，其中另一个时隙可以接收物理反馈信道，其中另一个时隙可以传输同步信息块等。可选地，在确定时隙格式后，终端设备需按照时隙格式在该时隙传输和/或接收对应信道。
第一时隙可以为侧链路时隙周期的所有时隙，第一时隙对应的静态时隙格式可以为指示在第一时隙传输和/或接收侧链路物理控制信道、侧链路物理数据信道、侧链路物理反馈信道、侧链路同步信道或者指示第一时隙为灵活时隙至少一项。
一种可能的实现方式中，假设侧链路时隙周期包括10个时隙，该10个时隙为第一时隙。在配置时对应的时隙格式为：7个时隙对应传输侧链路物理控制信道和/或侧链路物理数据信道，2个时隙对应为灵活时隙，1个时隙对应为传输侧链路同步信道。被指示为对应传输侧链路物理控制信道和/或侧链路物理数据信道、传输侧链路同步信道的时隙格式是固定的，发射终端不能调整其时隙格式。而被指示为灵活时隙的时隙，可以由发射终端根据数据传输任务来确定，灵活时隙可以被指示为以下至少一项：
传输或者接收侧链路物理控制信道和/或侧链路物理数据信道，接收或者传输侧链路物理反馈信道，传输或者接收侧链路同步信息块。
第二时隙可以为第一时隙中被指示为灵活时隙的时隙，第二时隙对应的灵活时隙格式可以用于指示在第二时隙传输和/或接收以下至少一项：
侧链路物理控制信道，侧链路物理数据信道，侧链路物理反馈信道，侧链路同步信息块。可选地，侧链路物理反馈信道由接收终端传输。
在相同非授权频谱上占用无线资源的终端设备都会接收到无线资源控制信令，因而，控制信息可以仅指示侧链路时隙周期内应用于第二时隙的灵活时隙格式，以使接收终端知晓侧链路时隙周期中灵活时隙对应的灵活时隙格式，为后续传输数据提供基础。
可选地，为了进一步提高数据传输的稳定性，控制信息还可以用于指示侧链路时隙周期内应用于第一时隙的静态时隙格式，从而避免接收终端由于网络质量等因素未接收到无线资源控制信令的情况。
可选地，控制信息可以为侧链路控制信息，侧链路控制信息通过侧链路物理控制信道和/或侧链路物理数据信道传输。
可选地，侧链路控制信息作为公共侧链路控制信息通过侧链路物理控制信道传输。
可选地，控制信息可以为侧链路无线资源控制信令或侧链路控制信息，以降低物理层控制信息的开销。
NR Sidelink传输与NR下行传输类似，都是基于传统的OFDM。当一个终端设备进行Sidelink传输时，会给终端配置一个Sidelink资源池，资源池定义了一个载波上可用于Sidelink通信的全部时间/频率资源。可选地，在时域上资源池为一个时隙集合，按照资源池周期重复。在频域上，资源池为一个连续的子信道集合，每个子信道由一些连续的资源块组成。
尽管资源池的配置在时域是以时隙为粒度，但并不意味着一个Sidelink时隙的所有 符号都要用于Sidelink传输。网络可以加以限制，使得一个Sidelink时隙内连续符号的有限集真正可以用于Sidelink通信，可以通过下面的配置来实现：
可用于Sidelink通信的连续符号集的第一个符号，范围在符号0到符号7之间。
可用于Sidelink通信的连续符号数，范围在7～14个符号。
通过这种方式，可以在Sidelink通信和传统的上下行通信共享一个载波时确保一个时隙第一个和/或最后几个符号可用于上行或下行控制信令。
在Sidelink有特定载波或者在非授权载波上的情况下，通常假定一个Sidelink时隙里的所有符号都可用于Sidelink通信。
因而，本实施例中的灵活时隙格式有至少一种。为了进一步详细说明灵活时隙格式，下面将结合图4a-图4f进行说明。
灵活时隙格式可以为：
第一时隙格式，第一时隙格式用于指示第二时隙对应传输侧链路物理控制信道和/或侧链路物理数据信道。该时隙格式可以用于指示在该灵活时隙发射终端传输物理数据和/或控制信息。
第二时隙格式，第二时隙格式用于指示在第二时隙传输侧链路物理控制信道和/或侧链路物理数据信道，以及接收终端传输侧链路物理反馈信道。该时隙格式可以用于指示在该灵活时隙发射终端传输物理数据和/或控制信息，以及接收终端传输反馈信息。
反馈信息可以包括HARQ反馈和/或信道质量反馈等。
第三时隙格式，第三时隙格式用于指示第二时隙接收终端对应传输侧链路物理反馈信道。该时隙格式仅用于指示该灵活时隙接收终端传输反馈信息。
第四时隙格式，第四时隙格式用于指示第二时隙对应传输侧链路同步信息块。该时隙格式仅用于指示该灵活时隙发射终端传输侧链路同步信息块，以实现时间上的同步。
可选地，第一时隙格式如图4b所示，第一时隙格式中第一个符号为自动增益控制符号，和/或，也可以用于承载侧链路物理控制信道和/或侧链路数据信道的一部分，最后一个符号为第一保护符号，第一个符号与最后一个符号之间的符号用于传输侧链路物理控制信道和/或侧链路数据信道。
第二时隙格式中第一个符号为自动增益控制符号，和/或，也可以用于承载侧链路物理控制信道和/或侧链路数据信道的一部分，第一个符号之后的至少一个符号用于传输侧链路物理控制信道和/或侧链路数据信道，至少一个符号之后的符号为第二保护符号，最后一个符号为第一保护符号，第一保护符号与第二保护符号之间的符号用于传输侧链路物理反馈信道。
第二时隙格式可以按照实际需求来设置用于传输侧链路物理控制信道和/或侧链路数据信道的符号数量以及用于传输侧链路物理反馈信道符号的数量。
若静态时隙格式中传输侧链路物理控制信道和/或侧链路数据信道的时隙数量较多，可以将传输侧链路物理反馈信道符号的数量设置为至少两个，从而满足接收终端需要反馈多于2比特的反馈信息的需求。
若其他灵活时隙的灵活时隙格式中传输侧链路物理控制信道和/或侧链路数据信道的符号数量较多，则当前灵活时隙的灵活时隙格式可以增加传输侧链路物理反馈信道符号的数量。
在一种可能的实现方式中，如图4c所示，用于传输侧链路物理控制信道和/或侧链路数据信道的符号数量为9个，用于传输侧链路物理反馈信道符号的数量为2个。
在一种可能的实现方式中，如图4d所示，用于传输侧链路物理控制信道和/或侧链路数据信道的符号数量为5个，用于传输侧链路物理反馈信道符号的数量为6个。
第三时隙格式中，如图4e所示，第一个符号为自动增益控制符号，和/或，也可以用于承载侧链路物理反馈信道的一部分，最后一个符号为第一保护符号，第一个符号与最后一个符号之间的符号用于传输侧链路物理反馈信道。
第四时隙格式中，如图4a所示，第一个符号为自动增益控制符号，和/或，也可以用于承载侧链路广播信道和/或解调参考信号的一部分，第二和第三个符号用于传输侧链路主同步序列，第四和第五个符号用于传输侧链路辅同步序列，第六至第十三个符号用于传输侧链路广播信道，最后一个符号为第一保护符号。第四时隙格式用于传输同步相关信息。
可选地，第一保护符号和第二保护符号上不承载信道和/或信号。
可选地，控制信息中可以包括指引灵活时隙格式的信息，比如可以采用比特域中包含的至少一个比特块来进行指引。比特块的数值与灵活时隙格式具有映射关系，从而使比特块的不同取值对应不同的灵活时隙格式。
在一种可能的实现方式中，比特块数值为1时对应第一时隙格式，数值为2时对应第二时隙格式，数值为3时对应第三时隙格式，数值为4时对应第四时隙格式。
又比如，可以采用预设表格，通过预先构建比特块的数值与预设表格中存储的灵活时隙格式之间的映射关系来指示灵活时隙格式。预设表格可以由无线资源控制信令来进行配置。
在一种可能的实现方式中，比特块数值为5时对应表格中第一时隙格式，数值为6时对应表格中第二时隙格式，数值为7时对应表格中第三时隙格式，数值为8时对应表格第四时隙格式。
在一种可能的实现方式中，比特域中的至少一个比特块对应一个时隙周期内的一个时隙。
在一种可能的实现方式中，如图4f所示，侧链路时隙周期为10个时隙，无线资源控制信令配置的静态时隙格式为：
第1-3，第5-7以及第8时隙即图中为数字1的时隙被配置为传输侧链路物理控制信道和/或侧链路物理数据信道。
第4和第8时隙即图中为X的时隙被配置为灵活时隙，灵活时隙需发射终端进一步配置具体时隙格式。
最后的时隙即图中为数字0的时隙被配置为传输侧链路同步信息块。
在本实现方式中，如图4f所示，第4时隙由发射终端配置为第一时隙格式，第8时隙由发射终端配置为第二时隙格式，且用于传输侧链路物理反馈信道符号的数量为7个，以满足整个侧链路时隙周期内对反馈信息的需求，还可以降低收发切换点的数量，降低信道丢失概率。若采用现有技术中的半静态配置方式，需要采用更多的时隙来配置传输侧链路物理反馈信道符号，且每个时隙传输侧链路物理反馈信道符号数量固定，从而形成更多的收发切换点，信道丢失概率较高。
为了进一步提高发射终端与接收终端之间传输的稳定性，可以增加侧链路控制信息的发送次数，也可以在接收终端由于网络状况等原因未接收到指示灵活时隙格式的控制信息时，预先设置灵活时隙对应的灵活时隙格式。
比如，在一般情况下，可以预先设置为第二时隙格式或第三时隙格式，以满足反馈信息传输的需求。也可以按照实际需求预先设置为第一时隙格式和/或第四时隙格式等，本实施例对此不作限定。
在一种可能的实现方式中，控制信息中可以包括指示灵活时隙格式的信息，后续收到的控制信息可以修改之前收到的控制信息所指示的灵活时隙格式。
图9为本申请实施例提供的处理方法的流程示意图四，本实施例以执行本处理方法的主体为终端设备(如UE)为例进行示例说明，当终端设备作为发射终端处理相关任务时，由于非授权频谱的信道抢占特性，可以先确定信道占据时间，以为后续的数据传输提供良好基础，如图9所示，该方法包括：
S61，进行第一先听后发操作，以确定信道占据时间。
发射终端在进行第一先听后发操作时，可以监听到信道是否可以被占用，以及信道占据时间。信道占据时间存在预设的上限，因而，确定出的信道占据时间不能超过预设的上限时间。
可选地，第一先听后发操作为信道接入流程类型1。信道接入流程类型1用于在同一COT内发起一个或者多个传输。通过执行随机退避的LBT流程来评估信道是否可用。首先，发射终端监听信道并等待，直到某信道至少在被称为延迟周期的一段时间内可用为止。延迟周期由一个16μs加若干个9μs时隙组成，延迟周期的长度取决于优先级类别。如果每个9μs时隙中至少有4μs时间内的接收能量低于阈值，则说明信道可用。一旦信道(至少)在延迟周期内被确认可用，发射机就启动随机退避操作，即等待一段随机的时间。 退避过程首先在竞争窗口内用一个随机数初始化退避计数器。该随机数来自均匀分布[0，CW]，以9μs的倍数表示传输前信道必须保持可用的持续时间。如果信道在每个9μs时隙被检测到空闲，则退避计数器减1；反之，每当信道被检测到繁忙时，则退避计数器保持不变，直到信道空闲时间达到延迟周期。每个9μs时隙的空闲检测遵循与前面描述的相同规则，即接收能量低于阈值。一旦退避计数器归零，随机退避过程就完成了，此时发射机已经获得信道，并且可以使用信道进行传输，直到达到该优先级类别所对应的最大信道占用时间。
S62，在信道占据时间内向接收终端发送控制信息。
在信道占据时间内向接收终端发送控制信息以使接收终端可以知晓进行数据传输的相关信息。可选地，相关信息可以包括时间、数据、传输方式等。
可选地，信道占据时间包括信道占据时间的结束时间。结束时间为根据信道占据时间是否与同步时隙发生重叠的结果和/或是否在同步时隙传输同步信息的结果确定出来的。
同步时隙为通过侧链路同步信道传输同步信息的第一时隙，同步时隙传输同步信息是侧链路时隙周期中必须执行的过程。
每次信道占据时间的起始时间与结束时间是不同的，信道占据时间内可能会存在与同步时隙发生重叠的情况，也可能不存在与同步时隙发生重叠的情况。当信道占据时间与同步时隙发生重叠时，根据发射终端的处理方式的不同，会影响信道占据时间的长短。
具体如下：
可选地，若信道占据时间与同步时隙发生重叠，且在同步时隙传输同步信息，则在传输同步信息后，进行第二先听后发操作，以确定信道是否在传输同步信息后继续占据，根据信道是否在传输同步信息后继续占据的结果确定结束时间。此次进行的第二先听后发操作相比第一先听后发操作的监听时间更短，执行整体时间更短，从而可以降低发射终端在同步时隙传输同步信息后的衔接时间，提高传输效率。
可选地，若确定信道可在传输同步信息后继续占据，则确定信道占据时间的结束时间为信道占据时间的原始结束时间。若确定信道不可在传输同步信息后继续占据，则确定信道占据时间的结束时间为同步时隙。
可选地，在确定可以继续占据后，发射终端将按照侧链路时隙周期以及对应的时隙格式进行数据传输。在确定不可在传输同步信息后继续占据时，信道占据时间在同步时隙时已经结束，将由其他占用信道的终端进行后续数据传输。
可选地，若信道占据时间与同步时隙发生重叠，且不在同步时隙传输同步信息，则信道占据时间的结束时间为同步时隙的前一时隙。若发射终端不在同步时隙传输同步信息，此时，发射终端仅能在同步时隙的前一时隙占用信道，而在同步时隙时，不能继续占用信道，因而，信道占据时间的结束时间为同步时隙的前一时隙。
可选地，若信道占据时间不与同步时隙发生重叠，则确定信道占据时间的结束时间为信道占据时间的原始结束时间。在信道占据时间未与同步时隙发生重叠时，信道占据时间将在原始结束时间结束，不会受到同步时隙的影响。
可选地，第二先听后发操作为信道接入流程类型2。根据COT中间传输间隙的持续时间，信道类型2可以有三种子类型：
类型2A，当两次传输之间的间隙为25μs时使用；
类型2B，当两次传输之间的间隙为16μs时使用；
类型2C，当两次传输之间的间隙小于16μs时使用；
类型2A和类型2B可以被视为没有随机退避的类型1，如果检测到信道空闲，就申明其可用，如果检测到信道繁忙，就说明无法使用COT。如果在上一次传输之后的16μs之内发生下一次传输，则在传输突发之间不需要进行信道空闲检测，这称为信道接入流程2C。
可选地，在应用于非授权频谱时，发射终端可以接收用于指示侧链路时隙周期内应用于第一时隙的静态时隙格式的无线资源控制信令。
控制信息可以用于指示侧链路时隙周期内应用于第二时隙的灵活时隙格式。
无线资源控制信令，可以由网络侧设备比如基站生成并发送，无线资源控制信令一般配置有频率资源、时间资源、码资源、功率资源和/或空间资源等相关信息，可以指示终 端设备使用无线网络资源。
侧链路时隙周期一般包括至少一个时隙，每个时隙按照时隙格式的不同，可以传输和/或接收不同的信道/数据，例如其中一个时隙可以传输物理信道和/或物理控制信道，其中另一个时隙可以接收物理反馈信道，其中另一个时隙可以传输同步信息块等。可选地，在确定时隙格式后，终端设备需按照时隙格式在该时隙传输和/或接收对应数据/信道。
第一时隙可以为侧链路时隙周期的所有时隙，第一时隙对应的静态时隙格式可以为指示在第一时隙传输和/或接收侧链路物理控制信道、侧链路物理数据信道、侧链路物理反馈信道、侧链路同步信道或者指示第一时隙为灵活时隙至少一项。
一种可能的实现方式中，假设侧链路时隙周期包括10个时隙，该10个时隙为第一时隙。在配置时对应的第一时隙格式为：7个时隙对应传输侧链路物理控制信道和/或侧链路物理数据信道，2个时隙对应为灵活时隙，1个时隙对应为传输侧链路同步信道。被指示为对应传输侧链路物理控制信道和/或侧链路物理数据信道、传输侧链路同步信道的时隙格式是固定的，发射终端不能调整其时隙格式。而被指示为灵活时隙的时隙格式，可以由发射终端根据数据传输任务等信息来确定，灵活时隙可以被指示为以下至少一项：
传输或者接收侧链路物理控制信道和/或侧链路物理数据信道，接收或者传输侧链路物理反馈信道，传输或者接收侧链路同步信息块。
第二时隙可以为第一时隙中被指示为灵活时隙的时隙，第二时隙对应的灵活时隙格式可以用于指示在第二时隙传输和/或接收以下至少一项：
侧链路物理控制信道，侧链路物理数据信道，侧链路物理反馈信道，侧链路同步信息块。可选地，侧链路物理反馈信道由接收终端传输。
在相同非授权频谱上占用无线资源的终端设备都会接收到无线资源控制信令，因而，控制信息可以仅指示侧链路时隙周期内应用于第二时隙的灵活时隙格式，以使接收终端知晓侧链路时隙周期中灵活时隙对应的灵活时隙格式，为后续传输数据提供基础。
可选地，为了进一步提高数据传输的稳定性，控制信息还可以用于指示侧链路时隙周期内应用于第一时隙的静态时隙格式，从而避免接收终端由于网络质量等因素未接收到无线资源控制信令的情况。
可选地，控制信息可以为侧链路控制信息，侧链路控制信息通过侧链路物理控制信道和/或侧链路物理数据信道传输。
可选地，侧链路控制信息作为公共侧链路控制信息通过侧链路物理控制信道传输。
可选地，控制信息可以为侧链路无线资源控制信令或侧链路控制信息，以降低物理层控制信息的开销。
NRSidelink传输与NR下行传输类似，都是基于传统的OFDM。当一个终端设备进行Sidelink传输时，会给终端配置一个Sidelink资源池，资源池定义了一个载波上可用于Sidelink通信的全部时间/频率资源。可选地，在时域上资源池为一个时隙集合，按照资源池周期重复。在频域上，资源池为一个连续的子信道集合，每个子信道由一些连续的资源块组成。
尽管资源池的配置在时域是以时隙为粒度，但并不意味着一个Sidelink时隙的所有符号都要用于Sidelink传输。网络可以加以限制，使得一个Sidelink时隙内连续符号的有限集真正可以用于Sidelink通信，可以通过下面的配置来实现：
可用于Sidelink通信的连续符号集的第一个符号，范围在符号0到符号7之间。
可用于Sidelink通信的连续符号数，范围在7～14个符号。
通过这种方式，可以在Sidelink通信和传统的上下行通信共享一个载波时确保一个时隙第一个和/或最后几个符号可用于上行或下行控制信令。
在Sidelink有特定载波或者在非授权载波上的情况下，通常假定一个Sidelink时隙里的所有符号都可用于Sidelink通信。
因而，本实施例中的灵活时隙格式有至少一种。为了进一步详细说明灵活时隙格式，下面将结合图4a-图4f进行说明。
灵活时隙格式可以为：
第一时隙格式，第一时隙格式用于指示第二时隙对应传输侧链路物理控制信道和/或侧链路物理数据信道。该时隙格式可以用于指示在该灵活时隙发射终端传输物理数据和/ 或控制信息。
第二时隙格式，第二时隙格式用于指示在第二时隙传输侧链路物理控制信道和/或侧链路物理数据信道，以及接收终端传输侧链路物理反馈信道。该时隙格式可以用于指示在该灵活时隙发射终端传输物理数据和/或控制信息，以及接收终端传输反馈信息。
反馈信息可以包括HARQ反馈和/或信道质量反馈等。
第三时隙格式，第三时隙格式用于指示第二时隙接收终端对应传输侧链路物理反馈信道。该时隙格式仅用于指示该灵活时隙接收终端传输反馈信息。
第四时隙格式，第四时隙格式用于指示第二时隙对应传输侧链路同步信息块。该时隙格式仅用于指示该灵活时隙发射终端传输侧链路同步信息块，以实现时间上的同步。
可选地，第一时隙格式如图4b所示，第一时隙格式中第一个符号为自动增益控制符号，和/或，也可以用于承载侧链路物理控制信道和/或侧链路数据信道的一部分，最后一个符号为第一保护符号，第一个符号与最后一个符号之间的符号用于传输侧链路物理控制信道和/或侧链路数据信道。
第二时隙格式中第一个符号为自动增益控制符号，和/或，也可以用于承载侧链路物理控制信道和/或侧链路数据信道的一部分，第一个符号之后的至少一个符号用于传输侧链路物理控制信道和/或侧链路数据信道，至少一个符号之后的符号为第二保护符号，最后一个符号为第一保护符号，第一保护符号与第二保护符号之间的符号用于传输侧链路物理反馈信道。
第二时隙格式可以按照实际需求来设置用于传输侧链路物理控制信道和/或侧链路数据信道的符号数量以及用于传输侧链路物理反馈信道符号的数量。
若静态时隙格式中传输侧链路物理控制信道和/或侧链路数据信道的时隙数量较多，可以将传输侧链路物理反馈信道符号的数量设置为至少两个，从而满足接收终端需要反馈多于2比特的反馈信息的需求。
若其他灵活时隙的灵活时隙格式中传输侧链路物理控制信道和/或侧链路数据信道的符号数量较多，则当前灵活时隙的灵活时隙格式可以增加传输侧链路物理反馈信道符号的数量。
在一种可能的实现方式中，如图4c所示，用于传输侧链路物理控制信道和/或侧链路数据信道的符号数量为9个，用于传输侧链路物理反馈信道符号的数量为2个。
在一种可能的实现方式中，如图4d所示，用于传输侧链路物理控制信道和/或侧链路数据信道的符号数量为5个，用于传输侧链路物理反馈信道符号的数量为6个。
第三时隙格式中，如图4e所示，第一个符号为自动增益控制符号，和/或，也可以用于承载侧链路物理反馈信道的一部分，最后一个符号为第一保护符号，第一个符号与最后一个符号之间的符号用于传输侧链路物理反馈信道。
第四时隙格式中，如图4a所示，第一个符号为自动增益控制符号，和/或，也可以用于承载侧链路广播信道和/或解调参考信号的一部分，第二和第三个符号用于传输侧链路主同步序列，第四和第五个符号用于传输侧链路辅同步序列，第六至第十三个符号用于传输侧链路广播信道，最后一个符号为第一保护符号。第四时隙格式用于传输同步相关信息。
可选地，第一保护符号和第二保护符号上不承载信道和/或信号。
可选地，控制信息中可以包括指示灵活时隙格式的信息，比如可以采用比特域中包含的至少一个比特块来进行指示。比特块的数值与灵活时隙格式具有映射关系，从而使比特块的不同取值对应不同的灵活时隙格式。
在一种可能的实现方式中，比特块数值为1时对应第一时隙格式，数值为2时对应第二时隙格式，数值为3时对应第三时隙格式，数值为4时对应第四时隙格式。
又比如，可以采用预设表格，通过预先构建比特块的数值与预设表格中存储的灵活时隙格式之间的映射关系来指示灵活时隙格式。预设表格可以由无线资源控制信令来进行配置。
在一种可能的实现方式中，比特块数值为5时对应表格中第一时隙格式，数值为6时对应表格中第二时隙格式，数值为7时对应表格中第三时隙格式，数值为8时对应表格第四时隙格式。
在一种可能的实现方式中，比特域中的至少一个比特块对应一个时隙周期内的一个时 隙。
在一种可能的实现方式中，如图4f所示，侧链路时隙周期为10个时隙，无线资源控制信令配置的静态时隙格式为：
第1-3，第5-7以及第8时隙即图中为数字1的时隙被配置为传输侧链路物理控制信道和/或侧链路物理数据信道。
第4和第8时隙即图中为X的时隙被配置为灵活时隙，灵活时隙需发射终端进一步配置具体时隙格式。
最后的时隙即图中为数字0的时隙被配置为传输侧链路同步信息块。
在本实现方式中，如图4f所示，第4时隙由发射终端配置为第一时隙格式，第8时隙由发射终端配置为第二时隙格式，且用于传输侧链路物理反馈信道符号的数量为7个，以满足整个侧链路时隙周期内对反馈信息的需求，还可以降低收发切换点的数量，降低信道丢失概率。若采用现有技术中的半静态配置方式，需要采用更多的时隙来配置传输侧链路物理反馈信道符号，且每个时隙传输侧链路物理反馈信道符号数量固定，从而形成更多的收发切换点，信道丢失概率较高。
为了进一步提高发射终端与接收终端之间传输的稳定性，可以增加侧链路控制信息的发送次数，也可以在接收终端由于网络状况等原因未接收到指示灵活时隙格式的控制信息时，预先设置灵活时隙对应的灵活时隙格式。
比如，在一般情况下，可以预先设置为第二时隙格式或第三时隙格式，以满足反馈信息传输的需求。也可以按照实际需求预先设置为第一时隙格式和/或第四时隙格式等，本实施例对此不作限定。
在一种可能的实现方式中，控制信息中可以包括指示灵活时隙格式的信息，后续收到的控制信息可以修改之前收到的控制信息所指示的灵活时隙格式。

可选地，为了进一步提高发射终端与接收终端之间传输的稳定性，可以增加侧链路控制信息的发送次数，也可以在接收终端由于网络状况等原因未接收到指示灵活时隙格式的控制信息时，预先设置灵活时隙对应的灵活时隙格式。
接收终端在与发射终端建立连接时，会对控制信息进行检测，若未接收到控制信息，或控制信息损坏，则接收终端对控制信息的检测处理结果为检测失败。此时，接收终端响应于对控制信息的检测处理结果为检测失败，确定灵活时隙格式为预设时隙格式。
一般情况下，预设时隙格式可以预先设置为第二时隙格式或第三时隙格式，以满足反馈信息传输的需求。也可以按照实际需求预先设置为第一时隙格式和/或第四时隙格式等，本实施例对此不作限定。
