信息发送方法、接收方法及设备
相关申请的交叉引用
本申请主张在2019年9月25日在中国提交的中国专利申请号No.201910910633.9的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，特别是指一种信息发送方法、接收方法及设备。
背景技术
在第五代(5 th generation，5G)新无线接入技术(NR Radio Access，NR)智能网联汽车技术(Vehicle-to-Everything，V2X)系统中,终端与终端之间使用PC5口(直通链路，Sidelink)进行直接通信。在进行业务数据传输之前，首先需要进行通信的两个终端之间在PC5口(Sidelink)建立同步。建立同步的方法就是一个终端A发送同步与广播信号，另外一个终端B接收终端A发送的同步与广播信号，一旦终端B接收并解调成功，这两个终端就能够建立同步，为下一步直接通信做好了准备。
NR V2X Sidelink做同步信息发送时，需要采用同步信号块(Synchronization Signal Block，SSB)的方式，Sidelink链路上的SSB被称为S-SSB。SSB图案中包括有Sidelink主同步信号(Sidelink Primary Synchronization Signal，S-PSS)，Sidelink辅同步信号(Sidelink Secondary Synchronization Signal，S-SSS)，以及Sidelink广播信道(Physical Sidelink Broadcast Channel，PSBCH)。为了降低复杂度，S-SSB的发送可能不会采取波束扫描的方式，而是发送一次全向波束或者重复发送多次相同的波束。
在V2X系统中，为了避免V2X UE(User Equipment，用户设备)对Uu UE的干扰(注：V2X通信是UE与UE之间的通信，Uu通信是基站与UE之间的通信)，V2X UE只能在上行载波或上行时隙中发送或接收直通链路数据，也就是说所有的直通链路通信仅仅会发生在上行载波或上行时隙中。在 NR中，一个时隙格式包括有下行时隙、灵活时隙或上行时隙，因此，需要将时隙格式信息通知给V2X UE，这样V2X UE就可以选择仅仅在上行时隙中进行直通链路通信。
然而，在V2X系统中，进行直通链路通信的UE包括有位于基站覆盖内的UE以及位于基站覆盖外的UE。基站覆盖内的UE可以接收到基站发送的时隙格式信息，从而获知上行时隙的位置。但对于覆盖外UE，就无法获知上行时隙的位置，这样，如果覆盖外UE在下行时隙上发送直通链路数据，就会导致覆盖外UE对Uu UE的下行数据产生严重的干扰，从而导致直通链路通信和空口通信质量下降。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
如图1所示，本公开实施例的一种信息发送方法，应用于用户设备，包括：
步骤101，通过物理直通链路信道发送传输配置信息；其中，
所述传输配置信息包括第一指示信息，所述第一指示信息用于指示至少一个时隙是下行时隙、灵活时隙或上行时隙，和/或，指示至少一个符号是下行符号、灵活符号或上行符号；
所述物理直通链路信道至少包括：物理直通链路广播信道、物理直通链路共享信道和物理直通链路控制信道中的一种。
通过步骤101，该用户设备通过物理直通链路广播信道PSBCH、物理直通链路共享信道(Physical SideLink Shared Channel，PSSCH)和物理直通链路控制信道(Physical SideLink Control Channel，PSCCH)中的至少一信道，将自身获知的传输配置信息进行发送，使得Sidelink的对端用户设备接收到该传输配置信息，这样，若对端用户设备未处于基站覆盖范围，也能够获知该传输配置信息，并由其中的第一指示信息识别出上行时隙或符号，避免了在下行时隙或符号上发送直通链路数据，也就不会对Uu UE的下行数据产生干扰，提升了直通链路通信和空口通信质量。
如图2所示，用户设备1(UE1)和用户设备2(UE2)进行Sidelink通信，UE1位于基站覆盖范围内，UE2位于基站覆盖范围外。如此，UE1在接收基站对时隙或符号的传输配置，可了解到具体的传输配置信息，包括：上行时隙的配置信息、灵活时隙的配置信息、下行时隙的配置信息、上行符号的配置信息、灵活符号的配置信息和下行符号的配置信息中的至少一种；然后，将传输配置信息通过PSBCH、PSSCH和PSCCH中的至少一种发送到UE2，使得UE2即使接收不到基站的信息，也能够通过UE1获知基站对时隙或符号的传输配置，从而避免在下行时隙或符号上发送直通链路数据。
其中，应该知道的是，该实施例中，所述下行时隙是指整个时隙中所有符号都是下行符号；所述灵活时隙是指整个时隙中所有符号都是灵活符号；所述上行时隙是指整个时隙中所有符号都是上行符号；所述灵活符号为当前未被配置为上行或下行传输的符号。
其中，该灵活符号在后续可能内其它信令配置成上行或下行传输，也可能不被配置从而不做上行或下行传输。
可选地，所述第一指示信息为至少一个时隙或符号的传输格式图案；或者，
与所述至少一个时隙或符号的传输格式图案对应的标识。
这里，该第一指示信息可以为至少一个时隙或符号的传输格式图案，直接指示一个或多个时隙或符号的具体格式。例如，预先设定下行时隙集中在所有时隙的前端，所有的上行时隙集中在所有时隙的后端，对于待指示格式的16个时隙，由于最大可能16个时隙全部都是下行时隙，所以下行时隙的数量需要4bit信息指示，同理，上行时隙的数量也需要4bit信息指示，而夹在下行时隙和上行时隙中间的剩余时隙就是灵活时隙，所以共需要8bit来指示这16个时隙的具体格式，故图3所示的16个时隙的具体格式的指示信息为“01000010”。
当然，可预先设置传输格式图案与标识的对应关系，该标识(如索引号)和传输格式图案的对应关系配置在用户设备，如此，该第一指示信息可以为与至少一个时隙或符号的传输格式图案对应的标识，减少信令开销。用户设备接收到该标识，即可查找到与之对应的至少一个时隙或符号的传输格式图案。例如，16个时隙的传输格式图案与标识的对应关系如下表1所示：
Figure PCTCN2020109948-appb-000001
Figure PCTCN2020109948-appb-000002
表1
在UE发送第一指示信息为“00”，对端UE接收到该第一指示信息后即可确定，16个时隙的传输格式图案为与标识“00”对应的传输格式图案。
可选地，所述第一指示信息为：
基站与用户设备之间通信所使用的时分双工上行和下行链路图案信息；或者
基站与用户设备之间通信所使用的时隙格式指示信息；或者
基站与用户设备之间通信所使用的时分双工上行和下行链路图案信息中上行时隙的相关信息、上行符号的相关信息、灵活时隙的相关信息和灵活符号的相关信息中的至少一个；或者
基站与用户设备之间通信所使用的时隙格式指示信息中上行时隙的相关信息、上行符号的相关信息、灵活时隙的相关信息和灵活符号的相关信息中的至少一个；或者
将基站与用户设备之间通信所使用的时分双工上行和下行链路图案信息或基站与用户设备之间通信所使用的时隙格式指示信息去除冗余信息后的有效信息。
这里，用户设备可以将基站与用户设备之间通信所使用的时分双工上行和下行链路图案(Time Division Duplex Uplink-Downlink Pattern，TDD UL-DL Pattern)信息作为第一指示信息；或者，将基站与用户设备之间通信所使用的时隙格式指示信息(Slot Format Indication，SFI)作为第一指示信息；或者，将基站与用户设备之间通信所使用的TDD UL-DL Pattern中上行时隙的相关信息、上行符号的相关信息、灵活时隙的相关信息和灵活符号的相关信息中的至少一个作为第一指示信息；或者，将基站与用户设备之间通信所使用的SFI中上行时隙的相关信息、上行符号的相关信息、灵活时隙的相关信息和灵活符号的相关信息中的至少一个作为第一指示信息；或者，将基站与用户设备之间通信所使用的TDD UL-DL Pattern信息或SFI去除冗余后的有效信息。
其中，上行时隙的相关信息是将至少一时隙配置为上行时隙的信息；上行符号的相关信息是将至少一符号配置为上行符号的信息；灵活时隙的相关 信息是将至少一时隙配置为灵活时隙的信息；灵活符号的相关信息是将至少一符号配置为灵活符号的信息。而TDD UL-DL Pattern信息或SFI去除冗余后的有效信息更为简洁地指示了至少一时隙或符号的使用状况，节省传输资源。
可选地，所述第一指示信息包括7个比特的上行时隙指示信息。
这里，该第一指示信息可以仅包括7个比特的上行时隙指示信息，即第一指示信息为7个比特。当然，第一指示信息除上行时隙指示信息外，还可以包括其它指示信息。
可选地，所述第一指示信息还包括4个比特的上行符号指示信息。
这里，该第一指示信息包括7个比特的上行时隙指示信息之外，还包括4个比特的上行符号指示信息，即第一指示信息为11个比特。当然，第一指示信息不限于该7个比特的上行时隙指示信息和4个比特的上行符号指示信息，还可以包括其它指示信息，在此不再赘述。
还应该知道的是，该实施例，用户设备向对端用户设备发送该传输配置信息是通过PSBCH、PSSCH和PSCCH中的至少一种。
可选地，所述物理直通链路信道至少包括物理直通链路广播信道；
所述通过物理直通链路信道发送传输配置信息，包括：
在所述物理直通链路广播信道的载荷或所述物理直通链路广播信道的解调参考信号上携带所述传输配置信息。
如此，UE发送直通链路同步信号块S-SSB，该S-SSB包括直通链路主同步信号S-PSS、直通链路辅同步信号S-SSS以及PSBCH，其中PSBCH承载传输配置信息，具体由PSBCH payload(载荷)或PSBCH DMRS(Demodulation Reference Signal，解调参考信号)携带该传输配置信息，保证了传输配置信息传递的高可靠性与低时延。
例如，若传输配置信息占用14比特，而如图4所示的一个时隙中PSBCH payload可以容纳56bit，则14比特的传输配置信息可以由56bit的PSBCH payload所携带；若传输配置信息占用3比特，而如图4所示的时隙中PSBCH DMRS可以容纳3bit，则3比特的传输配置信息可以由PSBCH DMRS所携带。图4中，该时隙中还包括自动增益控制(Automatic Gain Control，AGC)、保 护间隔(Guard Period，GP)、S-PSS和S-SSS。
PSSCH主要承载V2X UE之间通信的数据、直通链路系统消息块(System Information Block，SIB)以及直通链路无线资源控制(Radio Resource Control，RRC)信令。所以，该实施例中，可选地，所述物理直通链路信道至少包括物理直通链路共享信道；
所述通过物理直通链路信道发送传输配置信息，包括：
在所述物理直通链路共享信道的系统消息块或无线资源控制信令上携带所述传输配置信息。
这里，传输配置信息由PSSCH承载，具体是PSSCH的SIB或RRC携带，如图5所示。
另外，PSCCH主要承载V2X UE之间通信的控制信息，包括有直通链路控制信息(Sidelink Control Information，SCI)等。故，可选地，所述物理直通链路信道至少包括物理直通链路控制信道；
所述通过物理直通链路信道发送传输配置信息，包括：
在所述物理直通链路控制信道的直通链路控制信息上携带所述传输配置信息。
这里，传输配置信息由PSCCH承载，具体是PSCCH的SCI携带，如图6所示。
在该实施例中，采用PSSCH或PSCCH承载传输配置信息，可以承载的数据量比较大，并降低了PSBCH的容量压力，可以让PSBCH有更多的空间承载其他的信息。
对于Sidelink的对端用户设备而言，在收到第一指示信息之后，还需要知道在该第一指示信息中配置的时隙格式的生效时刻，以便用户设备通过时隙格式信息来获知哪些时隙以及哪些符号是上行的。因此，可选地，所述传输配置信息还包括指示所述第一指示信息生效时间的第二指示信息。
可选地，所述第二指示信息为：
当前直通链路同步信号与广播信号块S-SSB所在同步时隙的下一个时隙；或者
当前S-SSB所在同步时隙的归属无线帧的第一个时隙；或者
当前同步周期内第一个S-SSB所在同步时隙的归属无线帧的第一个时隙。
如图6所示，在NR中，一个无线帧固定是10ms，每个无线帧中包括有10个子帧，每个子帧固定是1ms。对于15KHz子载波间隔，每个时隙Slot的持续时长是1ms。所以，对于15KHz子载波间隔，一个无线帧中包括有10个时隙。SSB在3号、8号、13号和18号时隙中发，3号时隙中发的是第1个S-SSB，8号时隙中发的是第2个S-SSB，13号时隙中发的是第3个S-SSB，18号时隙中发的是第4个S-SSB。假如当前收到的S-SSB是第3个S-SSB，就是13号时隙中发的S-SSB，而一个同步周期是160ms。
若第二指示信息为当前S-SSB所在同步时隙的下一个时隙，则生效时刻就是14号时隙；若第二指示信息为当前S-SSB所在同步时隙的归属无线帧的第一个时隙，则生效时刻就是10号时隙；若第二指示信息为当前同步周期内第一个S-SSB所在同步时隙的归属无线帧的第一个时隙，则生效时刻就是0号时隙。如此，该第二指示信息更为简单直观，当然，也可以是复杂的映射实现，在此不再赘述。
可选地，所述传输配置信息在一个同步周期内保持不变；或者
所述传输配置信息中，行时隙的配置信息、上行符号的配置信息、灵活时隙的配置信息和灵活符号的配置信息中的至少一个的上行时隙和/或上行符号和/或灵活时隙和/或灵活符号的配置信息在一个同步周期内保持不变。
这里，该传输配置信息在一个同步周期内保持不变；或者，在该传输配置信息中，仅有配置至少一个时隙为上行时隙、配置至少一个时隙为灵活时隙、配置至少一个符号为上行符号和配置至少一个符号为灵活符号的至少一种配置信息在一个同步周期内保持不变。
可选地，所述直通链路控制信息上携带的所述传输配置信息为动态变化的信息。
如此，通过PSCCH的SCI携带的传输配置信息是动态变化的信息，动态指示时隙格式的变化情况。
可选地，该实施例中，所述通过物理直通链路信道发送传输配置信息包括：
在所述物理直通链路广播信道上发送所述传输配置信息后，在所述物理 直通链路控制信道上周期性发送所述传输配置信息。
这里，传输配置信息在PSBCH上发送一次后，可进一步在PSCCH上周期性发送。
可选地，所述传输配置信息是基站将所有时隙全部配置为灵活时隙时，用户设备由时隙格式指示信息中获取的。
这里，基站会通过半静态配置信令将所有的时隙配置成灵活时隙，然后基站再通过SFI将灵活时隙配置成下行时隙或上行时隙，其中，SFI只能将灵活时隙配置成下行时隙或上行时隙，而不能修改半静态配置信令已经配置成下行或上行时隙的时隙格式。所以，UE由接收到的基站发送的SFI，就可以获知哪些灵活时隙被配置成了上行时隙，再将传输配置信息发给对端UE就可以了。当然，UE可直接将接收到的SFI作为传输配置信息转发对端UE。
可选地，所述传输配置信息是由基站配置的单一小区专用时分双工上行和下行链路图案中获取的。
这里，为降低传输开销，基站会仅仅配置一套小区专用时分双工上行和下行链路图案Cell-specific TDD UL-DL Pattern，如此，该传输配置信息可以是由该Cell-specific TDD UL-DL Pattern中获取的。
此外，当V2X UE配置了多个载波进行直通链路通信时，如果两个载波上配置了不同的时隙格式，就需要将这两个载波上的传输配置信息都发送出去，会带来信令开销的增加，并且很可能会导致传输配置信息无法通过PSBCH承载。因此，可选地，所述通过物理直通链路信道发送传输配置信息，包括：
在多载波进行直通链路通信的情况下，所述多载波通过物理直通链路信道发送相同的传输配置信息。
这样，在多载波进行直通链路通信的情况下，多个载波使用相同的传输配置信息，或被配置成相同的传输配置信息，如图7所示，载波1和载波2的时隙格式相同，降低了传输配置信息的传输开销。
综上所述，本公开实施例的方法，用户设备通过PSBCH、PSSCH和PSCCH中的至少一信道，将自身获知的传输配置信息进行发送，使得Sidelink的对端用户设备接收到该传输配置信息，这样，若对端用户设备未处于基站 覆盖范围，也能够获知该传输配置信息，并由其中的第一指示信息识别出上行时隙或符号，避免了在下行时隙或符号上发送直通链路数据，也就不会对Uu UE的下行数据产生干扰，提升了直通链路通信和空口通信质量。

需要说明的是，该装置是应用了上述信息接收方法的装置，上述信息接收方法的实施例的实现方式适用于该装置，也能够达到相同的技术效果。
本公开的另一实施例还提供了一种计算机可读存储介质，其上存储有计算机程序，所述程序被处理器执行时实现如上应用于用户设备的信息发送方法，或者，如上应用于用户设备的信息接收方法中的步骤。

所属领域的技术人员可以清楚地了解到，为描述的方便和简洁，上述描述的系统、装置和单元的具体工作过程，可以参考前述方法实施例中的对应过程，在此不再赘述。
在本申请所提供的实施例中，应该理解到，所揭露的装置和方法，可以通过其它的方式实现。例如，以上所描述的装置实施例仅仅是示意性的，例如，所述单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如多个单元或组件可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。另一点，所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口，装置或单元的间接耦合或通信连接，可以是电性，机械或其它的形式。
所述作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部单元来实现本实施例方案的目的。
另外，在本公开各个实施例中的各功能单元可以集成在一个处理单元中，也可以是各个单元单独物理存在，也可以两个或两个以上单元集成在一个单元中。
所述功能如果以软件功能单元的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。基于这样的理解，本公开的技术方案本质上或者说对相关技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质中，包括若干指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络设备等)执行本公开各个实施例所述方法的全部或部分步骤。而前述的存储介质包括：U盘、移动硬盘、ROM、RAM、磁碟或者光盘等各种可以存储程序代码的介质。
本领域普通技术人员可以理解实现上述实施例方法中的全部或部分流程，是可以通过计算机程序来控制相关的硬件来完成，所述的程序可存储于计算机可读取存储介质中，该程序在执行时，可包括如上述各方法的实施例的流 程。其中，所述的存储介质可为磁碟、光盘、只读存储器(Read-Only Memory，ROM)或随机存取存储器(Random Access Memory，RAM)等。
可以理解的是，本公开实施例描述的这些实施例可以用硬件、软件、固件、中间件、微码或其组合来实现。对于硬件实现，模块、单元、子单元可以实现在一个或多个专用集成电路(Application Specific Integrated Circuits，ASIC)、数字信号处理器(Digital Signal Processor，DSP)、数字信号处理设备(DSP Device，DSPD)、可编程逻辑设备(Programmable Logic Device，PLD)、现场可编程门阵列(Field-Programmable Gate Array，FPGA)、通用处理器、控制器、微控制器、微处理器、用于执行本公开所述功能的其它电子单元或其组合中。
对于软件实现，可通过执行本公开实施例所述功能的模块(例如过程、函数等)来实现本公开实施例所述的技术。软件代码可存储在存储器中并通过处理器执行。存储器可以在处理器中或在处理器外部实现。
上述范例性实施例是参考该些附图来描述的，许多不同的形式和实施例是可行而不偏离本公开精神及教示，因此，本公开不应被建构成为在此所提出范例性实施例的限制。更确切地说，这些范例性实施例被提供以使得本公开会是完善又完整，且会将本公开范围传达给那些熟知此项技术的人士。在该些图式中，组件尺寸及相对尺寸也许基于清晰起见而被夸大。在此所使用的术语只是基于描述特定范例性实施例目的，并无意成为限制用。如在此所使用地，除非该内文清楚地另有所指，否则该单数形式“一”、“一个”和“该”是意欲将该些多个形式也纳入。会进一步了解到该些术语“包含”及/或“包括”在使用于本说明书时，表示所述特征、整数、步骤、操作、构件及/或组件的存在，但不排除一或更多其它特征、整数、步骤、操作、构件、组件及/或其族群的存在或增加。除非另有所示，陈述时，一值范围包含该范围的上下限及其间的任何子范围。
以上所述是本公开的可选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本公开所述原理的前提下，还可以作出若干改进和润饰，这些改进和润饰也应视为本公开的保护范围。
