Description

信号模式的确定、信号模式的获得方法及装置、存储介质
本申请要求在2018年01月18日提交中国专利局、申请号为201810048720.3的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，例如涉及一种信号模式的确定、信号模式的获得方法及装置、存储介质。
背景技术
随着无线通信技术的发展和用户对通信需求的日益增加，为了满足更高、更快和更新的通信需要，第五代移动通信(5th Generation，5G)技术已成为未来网络发展的趋势。
在5G通信系统中，用户设备(User Equipment，UE)进行信号传输有2种模式：循环前缀正交频分复用(Cyclic Prefix-OFDM Orthogonal Frequency Division Multiplex，CP-OFDM)和基于离散傅氏变换的正交频分复用(Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing，DFT-S-OFDM)。当UE向网络侧发送信号时，可以根据配置使用其中一种模式生成发送信号，在相应的资源上向网络侧发送。从网络侧的角度来说，可以确定UE发送信号所使用的资源及模式，则网络侧按照相应的模式在相应资源上进行信号的接收。
在边链路(Sidelink)通信系统中，UE之间有业务需要传输时，UE之间的业务数据不经过网络侧的转发，而是直接由数据源UE通过Sidelink传输给目标UE，图1是根据相关技术的Sidelink通信结构的示意图，如图1所示，这种UE与UE之间直接进行通信的模式具有区别于传统蜂窝系统通信模式的特征，对于能够应用Sidelink通信的近距离通信用户来说，Sidelink通信不但节省了无线频谱资源，而且降低了核心网的数据传输压力，能够减少系统资源占用，增加蜂窝通信系统频谱效率，降低终端发射功耗，并在很大程度上节省网络运营成本。
在Sidelink通信系统中，UE之间使用Sidelink资源进行信息的传输，根据 具体的应用场景及业务类型等，Sidelink通信方式包括设备到设备(Device to Device，D2D)通信，车辆到车辆(Vehicle to Vehicle，V2V)通信等。
在相关技术的Sidelink通信中，UE使用物理边链路控制信道(Physical Sidelink Control Channel，PSCCH)资源发送Sidelink控制信息，使用PSSCH资源发送Sidelink数据时，在PSCCH或物理边链路共享信道(Physical Sidelink Shared Channel，PSSCH)资源上所发送的信号必须使用DFT-S-OFDM模式，也称为单载波频分多址接入(Single Carrier-Frequency Division Multiple Access SC-FDMA)模式。相应的，在Sidelink进行信号接收的UE监听Sidelink资源池中的资源，并采用接收DFT-S-OFDM信号的方式接收处理信号，如图2所示，UE在PSCCH资源池中盲检测接收边链路控制信息(Sidelink Control Information，SCI)，当检测到SCI信息后，根据SCI的指示接收PSSCH资源上的数据信息。
在相关技术的Sidelink通信方法中，UE使用边链路资源池(Sidelink resource pool)中的资源发送Sidelink信号。边链路资源池包括用于承载边链路控制信息的PSCCH资源池，，以及用于承载边链路数据业务信息的PSSCH资源池。UE在Sidelink发送信号固定使用DFT-S-OFDM模式。相应的，在Sidelink进行信号接收的UE监听Sidelink资源池中的资源，并采用接收DFT-S-OFDM信号的方式接收处理信号。
针对相关技术中，在边链路Sidelink上发送Sidelink信号时，不能确定发送Sidelink信号所使用的信号模式的情况，目前尚未提出有效的改善方案。

为了更好的理解以下实施例以及示例实施例的技术方案，以下先对一些实施例以及示例实施例中涉及的基本概念进行简单说明。
当UE在Sidelink进行信息的交互时，发送端UE在PSCCH资源上发送Sidelink控制信息SCI，向接收端UE指示所传输的Sidelink数据信息所使用的PSSCH资源，以及相关的控制信息，如调制编码方式(Modulation and Coding Scheme，MCS)，功率控制指示，数据重传指示等。发送端UE在SCI所指示的PSSCH资源上发送Sidelink数据。另外，UE还可以在物理边链路广播信道(Physical Sidelink Broadcast Channel，PSBCH)资源上发送Sidelink广播信息，在物理边链路发现信道(Physical Sidelink Discovery Channel，PSDCH)资源上发送Sidelink发现信息。

PSCCH资源池是指，用于承载Sidelink控制信息SCI的一组资源，由网络侧通过物理层或高层信令配置，或者由系统预配置。PSCCH资源池在时域上包含至少一个时域资源单元，时域资源单元包括以下任意一项：子帧(subframe)，时隙(slot)，符号(symbol)。PSCCH资源池在频域上包含一个或多个资源块(Resource Block，RB)，或者至少一个资源块组(Resource Block group，RBG)，所包含的多个RB或RBG可以连续或不连续。

需要说明的是，上述各个模块是可以通过软件或硬件来实现的，对于后者，可以通过以下方式实现，但不限于此：上述模块均位于同一处理器中；或者，上述各个模块以任意组合的形式分别位于不同的处理器中。
从以上的描述中，可以看出，上述实施例避免了在边链路Sidelink上发送Sidelink信号时，不能确定发送Sidelink信号所使用的信号模式的情况，进而实 现在边链路Sidelink上确定发送Sidelink信号所使用的信号模式。
以下结合示例实施例对上述数据处理方法进行说明，但不用于限定本申请实施例的保护范围。
示例实施例1
在本示例实施例提出了一种确定信号模式的方法，用于Sidelink信号可能采用多种模式进行发送时，发送端UE确定发送信号使用的信号模式的方法，以及接收端UE获得接收Sidelink信号模式的方法，使接收端UE能够获得所接收的Sidelink信号的模式，进而采用相应的接收处理方式对所接收的信号进行处理。避免了Sidelink信号模式不确定时，接收端UE无法接收信号的情况。
UE在Sidelink发送信号时，支持使用多种信号生成模式，分别称为模式一，模式二，...模式n，接收端UE需要确定所接收的信号所采用的模式。在下面的说明中，以Sidelink信号发送支持两种模式为例，例如模式一为CP-OFDM模式，模式二为DFT-S-OFDM模式。
UE发送Sidelink信号时，可以采用下列方法中的至少一种确定所使用的发送信号的信号模式：
1.由Sidelink资源池配置确定；
2.预定义/配置Sidelink信号模式；
3.由网络侧配置UE；
4.由UE选择发送Sidelink信号的模式；
5.由基准Sidelink信号模式确定其他至少一种关联Sidelink信号模式。
其中，UE确定Sidelink信号发送模式包括确定以下至少一种Sidelink信号的信号模式：PSCCH信号模式、PSSCH信号模式、PSBCH信号模式，以及PSDCH信号模式。
其中，PSCCH信号承载SCI信息并在PSCCH资源上发送的Sidelink信号，可以简称发送SCI信息的信号为PSCCH信号。类似的，Sidelink数据信息承载在PSSCH资源上，可以简称发送Sidelink数据信息的信号为PSSCH信号，承载Sidelink广播信息的在PSBCH资源上发送的信号为PSBCH信号，承载Sidelink发现信息的在PSDCH资源上发送的信号为PSDCH信号。
确定UE发送Sidelink信号的模式包括确定上述至少一种信号的模式，且同一个UE发送不同的Sidelink信号的发送模式可以相同，也可以不同。下面主要 以PSCCH信号和PSSCH信号为例进行说明，PSBCH与PSDCH信号模式的确定方法可相应类似使用。
在一个实施例中，UE发送Sidelink信号时，可以采用下列方法中的至少一种向接收端指示所使用的信号发送模式：
1.通过高层信令指示相应的Sidelink信号模式；
2.在SCI中指示相应PSSCH信号模式；
3.通过解调参考信号(Demodulation Reference Signal，DMRS)隐式指示Sidelink信号模式。
示例实施例2
当发送端UE需要在PSCCH资源或PSSCH资源上发送Sidelink信号时，首先需确定发送信号应采用的信号模式。当采用信号模式一生成发送信号时，则按照CP-OFDM模式的方法将待发送的SCI和Sidelink数据信息中的至少一种进行处理，生成待发送信号。包括将信息进行子载波映射(sub-carrier mapping)处理，M点离散傅氏逆变换(Inverse Discrete Fourier Transformation，IDFT)处理，加循环前缀(cyclic prefix，CP)处理，以及调制到射频(radio frequency)处理。
当采用信号模式二生成发送信号时，则按照DFT-S-OFDM模式的方法处理待发送的信息，包括将信息进行N点离散傅氏变换(Discrete Fourier Transformation，DFT)处理，子载波映射处理，M点离散傅氏逆变换处理，以及加循环前缀处理，最终发送信号，如图7所示。
可以看到，对于不同模式的信号，发送端UE生成信号的步骤是不同的。因此UE在Sidelink发送信号时，首先需要确定发送信号使用的信号模式，根据确定的信号模式对待发送的Sidelink控制信息和Sidelink数据信息中的至少一种进行处理并发送。
UE接收Sidelink信号时，需要获得所接收的Sidelink信号的模式，获得信号模式后，按照相应的模式对所接收的信号进行处理，并获得信号中承载的信息。
当Sidelink信号采用不同的模式时，接收处理信号的流程不同，以模式一为CP-OFDM和模式二为DFT-S-OFDM为例进行说明。
获得所接收Sidelink信号的信号模式的方法包括：
1.由Sidelink资源池配置确定；
2.预定义/配置Sidelink信号模式；
3.盲检测确定Sidelink信号模式；
4.通过发送端指示的高层和物理层信令中的至少一种指示确定Sidelink信号模式；
5.通过基准Sidelink信号模式确定另外至少一种关联Sidelink信号模式。
示例实施例3
当接收端UE在PSCCH资源或PSSCH资源上接收到某个Sidelink信号时，首先需获得此信号的信号模式。当所接收到的信号为模式一信号时，则按照接收CP-OFDM模式的方法处理所接收到的信号，包括将信号进行去循环前缀处理，M点离散傅氏变换处理，解子载波映射处理，以及信息检测处理。
当所接收到的信号为模式二信号时，则按照接收DFT-S-OFDM模式的方法处理所接收到的信号，包括将信号进行去循环前缀处理，M点离散傅氏变换处理，解子载波映射处理，N点离散傅氏逆变换处理，以及信息检测处理，如图8所示。
可以看到，对于不同模式的信号，接收端UE的处理步骤是不同的，因此UE在Sidelink接收信号时，需要在接收信号时首先获得此信号的信号模式，才能够按照相应的接收处理方式对所接收的信号进行处理。
下面对上述确定Sidelink信号发送模式，接收模式的方法分别进行说明。
方法一、由资源池配置确定Sidelink信号模式。
在Sidelink通信中，可用于发送Sidelink信号的物理资源构成Sidelink资源池，例如PSCCH资源池，PSSCH资源池。进行Sidelink通信的UE需要获得Sidelink资源池的配置信息，并使用Sidelink资源池中的资源发送Sidelink信号，并且在Sidelink资源池中接收来自其他UE的Sidelink信号。Sidelink资源池的配置信息可以由网络侧配置指示UE，或者由系统预配置，指示出相应Sidelink资源池上发送信号的信号模式。Sidelink资源池包括PSCCH资源池和PSSCH资源池中的至少一种。UE从网络侧接收配置信息，或者由系统预配置确定可用的Sidelink资源池及相应的Sidelink信号模式。UE可以同时支持多个Sidelink资源池配置，并使用其中的资源按照配置的信号模式发送Sidelink信号，或从多个资 源池中按照配置的信号模式接收Sidelink信号。
当Sidelink信号发送支持多种模式时，可以为每个Sidelink资源池配置相应的信号模式，即使用某个Sidelink资源池中的资源发送Sidelink信号时，必须使用此Sidelink资源池对应的信号模式，每个Sidelink资源池的信号模式唯一。相应的，在此资源池中接收Sidelink信号时，应以配置的信号模式进行接收处理。这里，Sidelink资源池包括PSCCH资源池和PSSCH资源池中的至少一种，PSCCH资源池与PSSCH资源池可配置使用相同或不同的信号模式。
UE在获得Sidelink资源池配置信息时，其中包括此Sidelink资源池对应的信号模式配置。则基于Sidelink资源池配置信息，UE可以确定，当UE使用此资源池中的资源发送Sidelink信号时，必须使用为此资源池配置的信号模式；当UE接收此资源池中的信号时，可以根据配置信息确定所接收的信号是所配置的信号模式，并按照相应信号模式的接收方法来处理在此资源池中接收到的信号。
另外，UE可根据Sidelink资源配置中指示的信号模式配置，作为UE进行Sidelink资源选择的依据。例如，UE仅支持模式一方式发送Sidelink信号，则当系统预配置有多个Sidelink资源池，且各个资源池相应的信号模式不同，UE可选择使用对应信号模式一的资源池，在所选择的资源池中选择资源进行Sidelink信号发送。或者，例如，UE当前的蜂窝通信上行信号采用模式二发送，则UE优先采用模式二发送Sidelink信号，则UE可根据Sidelink资源池配置，选择配置为信号模式二的资源池，在其中选择资源进行Sidelink信号的发送。
此外，方法一是在Sidelink信号模式与Sidelink资源池配置之间建立固定的关系，使UE通过获得Sidelink资源池配置信息确定相应的信号模式，避免UE接收Sidelink信号时进行模式盲检，有利于减少UE实现复杂度，降低UE功耗。
示例实施例4
UE从网络侧获得Sidelink资源池配置信息，其中包括多个PSCCH资源池的配置。例如，包括每个PSCCH资源池中包含的资源，以及相应的信号模式。根据配置信息，Sidelink资源池配置指示为：PSCCH资源池#1，#2使用模式一；PSCCH资源池#3，#4使用模式二。
UE在PSCCH资源池#1中选择一个PSCCH资源发送SCI，且根据资源池配置信息中的指示，UE将待发送的SCI信息按照模式一的方式生成信号，承载在PSCCH资源池#1中的PSCCH资源上发送。
UE在PSCCH资源池#2,#3,#4中接收信号，则根据资源池配置信息中的指示，UE在PSCCH资源池#2中盲检SCI信息时，采用模式一的方式处理所接收的信号，在PSCCH资源池#3，#4中盲检SCI信息时，采用模式二的方式处理所接收的信号，UE处理模式一，模式二信号的具体方法如示例实施例1中所述。例如，UE从所接收的信号中解析SCI，如图9所示。
方法二、预定义/配置Sidelink信号模式。
在Sidelink通信中，可以由网络侧配置或者由系统预定义Sidelink的信号模式，包括至少一种Sidelink信号的传输模式，如PSCCH信号模式，PSSCH信号模式，PSBCH信号模式。
UE在发送及接收Sidelink信号时按照网络侧配置的信号模式或系统预定义的信号模式发送或接收Sidelink资源上的信号，包括PSCCH信号、PSSCH信号以及PSBCH信号中的至少一种。其中，网络侧可以通过高层信令配置指示Sidelink PSCCH信号模式、PSSCH信号模式以及PSBCH信号模式中的至少一种，或者由系统预定义PSCCH信号模式、PSSCH信号模式以及PSBCH信号模式中的至少一种。在方法二中，网络侧公共配置的，或系统预定义的Sidelink信号模式为公共配置，即相同小区，或相同Sidelink通信组中的所有UE使用相同的配置。
在一个实施例中，发送端UE根据配置，使用指示的信号模式发送PSCCH信号、PSSCH信号以及PSBCH信号模式中的至少一种。相应的，接收端UE根据配置指示的信号模式，在相应资源上接收PSCCH信号、PSSCH信号以及PSBCH信号中的至少一种。
示例实施例5
UE接收网络侧的公共配置信息，其中指示了Sidelink相关的配置，包括Sidelink控制信道使用模式一用于承载SCI信息在PSCCH资源上发送。另外，对Sidelink数据信道采用的信号模式在SCI信息中指示，例如在SCI中设置1比特(bit)信号模式指示信息，用于指示此SCI对应的PSSCH资源上发送信号的信号模式为模式一或者模式二。
根据网络侧的配置，UE在Sidelink资源上发送信号时，以模式一生成承载SCI的信号，并在PSCCH资源上发送。而PSSCH信号模式由UE自主确定， UE选择使用与PSCCH相同的信号模式发送PSSCH信号，并在SCI信号中指示了相应PSSCH资源上发送Sidelink数据信息的信号的模式为模式一。则UE使用模式一在PSCCH资源上发送SCI信息，在相应的PSSCH资源上以模式一发送Sidelink数据信息，如图10所示。
根据网络侧的配置，UE在PSCCH资源池中检测接收SCI时，以模式一检测PSCCH资源上的信号，并从中解析获得SCI信息。例如，UE根据获得的SCI中的PSSCH信号模式的信号模式指示信息确定接收相应PSSCH信号的模式。其中，信号模式指示信息指示相应的PSSCH资源上发送的Sidelink数据信号使用了模式一，则UE在相应的PSSCH资源上，以模式一的接收处理方式接收信号，并获得相应的Sidelink数据信息，如图10所示。
方法三、网络侧配置UE Sidelink信号发送模式。
在Sidelink通信中，可以由网络侧通过UE专用的高层信令或物理层信令为UE配置Sidelink信号模式。
网络侧通过专用信令为UE配置Sidelink信号模式，与方法二中的配置不同，由于配置信令是独立下发给每个UE，即多个Sidelink UE的信号模式可以设置为相同模式或不同模式，而方法二中的配置信令是公共配置信令，即所有UE采用统一的Sidelink信号模式。方法三中各个UE独立的配置有利于Sidelink通信灵活的配置，以及适应于不同业务、能力、需求的Sidelink UE。
网络侧为UE配置的Sidelink信号模式中，可以包括以下任意一种配置方式：仅配置PSCCH信号模式；仅配置PSSCH信号模式；配置PSCCH和PSSCH信号模式。
另外，网络侧可以配置UE采用统一的信号模式发送PSCCH和PSSCH信号，则网络侧向UE的指示信令中仅通知一种信号模式，即达到指示PSCCH和PSSCH信号模式的作用。或者，网络侧配置UE可以采用不同的信号模式发送PSCCH和PSSCH信号，则网络侧向UE的指示信令可以通知PSCCH和PSSCH中至少一种的信号模式，对于网络侧未明确配置的信号模式，UE可以自行确定。
或者，网络侧可以通过高层信令配置指示UE，在Sidelink发送信号的信号模式与UE在蜂窝通信中的上行信号发送使用相同的信号模式。则网络侧不需要再为UE明确指示Sidelink信号模式。UE根据配置，使用向网络侧发送上行信 号的信号模式作为Sidelink信号模式，生成Sidelink信号并发送。
示例实施例6
UE接收网络侧的配置信令，其中指示了Sidelink相关的配置，包括Sidelink控制信道使用模式一用于承载SCI信息在PSCCH资源上发送，以及使用模式二发送PSSCH信号。
发送端UE根据网络侧的配置，在配置的Sidelink资源上分别使用模式一和模式二发送PSCCH信号及PSSCH信号。
此方法可以实现网络侧对Sidelink UE发送Sidelink信号的灵活配置，达到灵活协调各UE信号模式，降低接收复杂度，满足UE能力需求等作用。
方法四、UE选择Sidelink信号发送模式。
在Sidelink通信中，UE可以自主选择确定Sidelink信号模式，包括选择PSCCH信号模式和PSSCH信号模式中的至少一种。UE可以选择为PSCCH信号和PSSCH信号使用相同或不同的信号模式。例如，UE使用所选择信号模式发送PSCCH信号和PSSCH信号中的至少一种。
示例实施例7
UE从网络侧获得Sidelink资源池配置，其中包含了资源池中资源的配置信息，但网络侧未配置Sidelink信号模式或配置为两种模式都可支持，则UE可以自由选择Sidelink信号模式。
或者，网络侧通过信令配置UE，在Sidelink发送信号的信号模式由UE自行确定，则UE根据网络侧的指示，可以从Sidelink支持的信号模式中任意选择一种模式用于发送PSCCH信号和PSSCH信号中的至少一种。
或者，UE在D2D通信或V2X通信的专用载波上进行Sidelink通信，未接收到网络侧的配置指示信息，则UE须自主确定Sidelink信号模式，用于发送Sidelink信号。
UE自主确定Sidelink信号模式时，可以在所有可用信号模式中随机选择一种作为Sidelink信号发送模式，或者，UE可以依据UE本身的能力、业务需求、场景需求、蜂窝通信上行信号模式，对Sidelink信道监听的结果，对Sidelink信道测量的结果等因素，选择确定自身在Sidelink发送信号的信号模式。
UE在Sidelink资源上发送信号时，自主确定信号模式，UE根据自身能力， 当UE仅支持以模式一生成信号时，则UE确定Sidelink信号模式为模式一。例如，UE使用模式一生成Sidelink信号，在PSCCH资源上发送SCI。另外，UE在SCI信号中指示了相应PSSCH资源上发送Sidelink数据信息的信号的模式为模式一，则UE在所指示的PSSCH资源上以模式一发送Sidelink数据信息。
方法五、根据基准Sidelink信号信号模式确定关联Sidelink信号模式。
在Sidelink通信中，可以由网络侧配置或系统预定义确定由某一种Sidelink信号为基准信号，其他至少一种Sidelink信号为相关的关联Sidelink信号。并定义由基准Sidelink信号的信号模式确定相应关联Sidelink信号的信号模式，例如，定义关联Sidelink信号模式与基准Sidelink信号模式相同。
例如，基准Sidelink信号与关联Sidelink信号的关系包括但不限于：PSCCH信号为基准信号，PSSCH信号为关联信号；PSBCH信号为基准信号，PSCCH信号为关联信号；PSBCH信号为基准信号，PSCCH信号和PSSCH信号为关联信号；PSDCH信号为基准信号，PSCCH信号为关联信号；PSDCH信号为基准信号，PSCCH信号和PSSCH信号为关联信号。
或者，网络侧配置或系统预定义基准Sidelink信号模式与关联Sidelink信号模式之间的对应关系，例如表1所示。
表1
Figure PCTCN2019071728-appb-000001
另外，当采用PSDCH信号或PSBCH信号作为基准Sidelink信号时，还可以规定以基准Sidelink信号的信号模式作为相应Sidelink资源池中其他Sidelink信号的信号模式。
示例实施例8
UE从网络侧获得配置指示，基准Sidelink信号为PSBCH信号，PSCCH信号为相应的关联信号，且配置为关联信号采用与基准信号相同的信号模式。
UE根据配置指示，在资源池中监听接收PSBCH信号，判断并获得基准信号的信号模式为模式一，则UE应以模式一发送PSCCH信号。
或者，网络侧配置PSBCH为基准信号，并且定义其他Sidelink信号均为关联Sidelink信号，采用与基准信号相同的信号模式。
UE根据配置指示，在PSBCH资源上接收PSBCH信号后，判定基准信号模式为模式二，则相应的，UE在Sidelink发送其他信号都采用模式二进行发送。
示例实施例9
网络侧配置，或者系统预定义根据PSCCH信号模式确定相应的PSSCH信号模式，具体规则为PSCCH信号模式与相应的PSSCH信号模式相同。
UE在接收到PSCCH信号后，可以确定相应的PSSCH信号的模式与PSCCH信号模式相同。UE在接收PSSCH信号时，直接使用相应PSCCH信号的信号模式去接收处理PSSCH信号，不再需要对PSSCH信号模式进行盲检接收及判断。
这里，PSCCH信号及相应的PSSCH信号是指，PSCCH信号中承载的SCI信息指示了一个PSSCH信道资源，以及相应的控制信息，如MCS等，则被SCI指示的PSSCH资源上承载的PSSCH信号可以称为此PSCCH信号对应的PSSCH信号。
根据网络侧的配置，基准Sidelink信号为PSCCH信号，相应的关联Sidelink信号为PSSCH信号，关联信号采用与基准信号相同的信号模式。
根据此配置，接收端UE在PSCCH资源池中检测接收PSCCH信号，通过盲检测DMRS确定了PSCCH的信号模式为模式二。相应的，UE可以确定相应的PSSCH信号的信号模式同样为模式二。例如，UE在SCI所指示的PSSCH资源上以模式二接收处理PSSCH信号，从中解析获得Sidelink数据信息，如图11所示。
方法六、发送端指示所使用的Sidelink信号模式。
发送端发送Sidelink信号所使用的信号模式可以通过直接指示或间接指示的方式通知接收端，使接收端获得相应信号的信号模式，从而达到避免接收端盲检测，降低接收端处理复杂度的作用。
发送端UE采用直接指示或间接指示的方法向接收端指示相应的信号模式，可以由网络侧配置，或者由系统预定义。发送端UE根据配置或预定义，采用直 接指示，或间接指示的方法指示所使用的Sidelink信号模式。
直接指示的方法包括，发送端UE通过高层信令和物理层信令中的至少一种向接收端指示发送端UE发送Sidelink信号使用的信号模式。高层信令可以是发送端UE向接收端UE发送的RRC信令，也可以是发送端UE的广播类信息，没有特定接收目标UE。物理层信令为SCI，例如，在SCI中通过设置信号模式指示域，向接收端指示PSSCH信号的信号模式。
间接指示的方法包括，对Sidelink数据信道采用的信号模式可以通过相应的解调参考信号进行隐式指示。在PSBCH信号，PSCCH信号，PSSCH信号，PSDCH信号发送中，都携带有相应的DMRS，则可以通过相应DMRS使用不同的序列或不同的循环移位来间接指示相应信号的信号模式。
例如，在PSCCH信号中的DMRS可以间接指示此PSCCH信号和相应的PSSCH信号中至少一种的信号模式，或者在PSSCH信号中的DMRS间接指示了此PSSCH信号的信号模式。
不同DMRS序列或循环移位间接指示Sidelink信号模式的一个例子如表2所示，由网络侧配置或系统预定义，不同DMRS序列或循环移位对应指示的信号模式为：
表2
Figure PCTCN2019071728-appb-000002
其中，网络侧配置或系统预定义为不同的信号模式使用不同的DMRS序列，或者不同的DMRS循环移位，则发送端UE根据表2中的DMRS序列或循环移位的配置或预定义，使用相应的DMRS序列或循环移位生成PSCCH信号中携带的DMRS并发送，达到了间接指示PSSCH信号模式的作用。
示例实施例10
发送端UE根据网络侧的配置指示，使用模式一发送PSCCH信号和PSSCH信号。
当系统预定义发送端UE以直接指示的方法提示信号模式，则发送端UE在 SCI中以1bit信号模式指示位，向接收端UE指示PSSCH信号使用的信号模式，指示位bit为“1”表示采用模式一，bit为“0”表示采用模式二。接收端接收到SCI信息后，可以从相应的模式指示域中获得指示信息，确定相应的PSSCH信号模式，并根据指示在相应的PSSCH资源上以指示的模式接收PSSCH信号。
当系统预定义发送端UE以间接指示的方法指示信号模式，则发送端UE根据表2所示规则，在PSCCH信号的DMRS发送时，使用DMRS序列n1，序列n2，...，序列N中的一个序列，隐式指示了此PSCCH信号为模式一发送。也隐式指示了相应的PSSCH信号也采用模式一发送。接收端接收PSCCH信号时，通过检测DMRS序列，结合表2，即可以确定相应的信号模式。
方法七、接收端UE通过检测DMRS确定Sidelink信号模式。
接收端UE在Sidelink资源上通过盲检测DMRS确定Sidelink信号模式，包括检测确定PSCCH信号模式和PSSCH信号模式中的至少一种。
接收端UE可以通过检测PSCCH信号或PSSCH信号中的解调参考信号(Demodulation Reference Signal，DMRS)来确定相应的信号模式，例如，通过检测DMRS确定相应信号模式的方式包括：通过盲检DMRS序列确定信号模式；通过盲检DMRS循环移位确定信号模式。
其中，网络侧配置或系统预定义为不同的信号模式使用不同的DMRS序列，或者不同的DMRS循环移位，则UE根据配置或预定义，获得不同的Sidelink信号模式生成信号时可用的DMRS序列列表，或者相应的DMRS循环移位列表，如表2所示。则接收端UE在接收Sidelink信号时可以通过接收检测信号中的DMRS序列或循环移位确定当前信号的信号模式。
示例实施例11
UE根据系统预定义，获得了Sidelink信号模式与相应的DMRS序列列表之间的对应关系，例如表2所示。则UE在Sidelink接收信号时，采用盲检测接收的方法，通过检测信号中的DMRS序列来确定相应的信号模式，并根据确定的信号模式接收处理相应信号。
根据表2，UE在PSCCH资源池中检测接收SCI时，按照PSCCH信道结构从中检测DMRS序列，并将检测到的DMRS序列与表2中的序列列表进行对照，当所检测到的DMRS序列为模式一对应的DMRS序列时，则确定当前接收的PSCCH 信号为模式一信号。例如，UE以模式一接收处理此PSCCH资源上的信号，并从中解析获得SCI信息；当所检测到的DMRS序列为模式二对应的DMRS序列时，则确定当前接收的PSCCH信号为模式二信号。例如，UE以模式二接收处理此PSCCH资源上的信号，并从中解析获得SCI信息，如图12所示。
或者，当系统预定义PSCCH信号中的DMRS隐式指示了此PSCCH信号及相应PSSCH信号的信号模式时，则接收端UE通过检测判断PSCCH信号中DMRS所指示的信号模式，可以确定此PSCCH信号的模式，以及此SCI信息指示的PSSCH信号的模式。
方法八、接收端UE根据SCI指示确定Sidelink信号模式。
UE在接收Sidelink信号时，会先接收解析PSCCH信号，获得SCI信息，再根据SCI指示的PSSCH资源接收PSSCH信号。因此，接收端UE确定PSSCH信号模式的方法除了上述方法六所述通过盲检测DMRS确定PSSCH信号模式，还可以通过已接收的PSCCH信号中的SCI指示来确定相应PSSCH信号的信号模式。
UE检测接收到PSCCH信号后，从中解析获得SCI指示信息，其中包含对相应PSSCH信号的信号模式的指示。则UE可以根据SCI的指示，在相应的PSSCH资源上按照指示的模式对PSSCH信号进行接收处理，并获得PSSCH资源上的Sidelink数据信息。
示例实施例12
系统预定义PSCCH信号模式固定采用模式一，且相应PSSCH信号的信号模式由发送端UE在相应的SCI中指示。
接收端UE在PSCCH资源池中按照固定的模式一检测接收PSCCH信号，从中获得SCI指示，其中指示了相应的PSSCH信号模式为模式二。例如，UE根据SCI的指示，在所指示的PSSCH资源上，按照指示的模式二接收处理PSSCH信号，从中解析获得Sidelink数据信息，如图13所示。
