资源指示方法、设备及系统
相关申请的交叉引用
本公开主张在2018年11月02日提交国家知识产权局、申请号为201811303088.9、申请名称为“一种资源指示方法、设备及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信技术领域，尤其涉及一种资源指示方法、设备及系统。
背景技术
在长期演进(Long Term Evolution，LTE)系统中，用户设备(User Equipment，UE)之间可以无需通过网络设备而采用旁链路(sidelink)技术直接进行数据传输。
目前，当发送端UE处于自主资源选择模式(即发送端UE自主分配传输资源)时，发送端UE可以为其预留物理旁链路共享信道(Physical Sidelink Shared Channel，PSSCH)资源，并且发送端UE可以无需通过网络设备而直接通过该PSSCH资源向接收端UE发送数据。
然而，由于在新空口(New Radio，NR)系统中，接收端UE接收到发送端UE发送的数据之后，接收端UE可能会向发送端UE发送表示该数据是否接收成功的反馈信息，因此如果接收端UE也按照上述方式为其预留用于承载反馈信息的传输资源，那么由于接收端UE和发送端UE都是独立为各自预留传输资源的，因此可能会使得接收端UE预留的传输资源与发送端UE预留的传输资源冲突，例如两个传输资源的时域资源冲突等。
发明内容
本申请实施例提供一种资源指示方法、设备及系统，以解决接收端UE预留的传输资源与发送端UE预留的传输资源冲突的问题。
为了解决上述技术问题，本申请实施例是这样实现的：
本申请实施例的第一方面，本申请实施例提供了一种资源指示方法。该方法应用于采用旁链路传输的过程中。该方法包括：第一设备确定第一资源，该第一资源用于传输第一反馈信息；第一设备向第二设备发送第一指示信息，该第一指示信息用于指示第一资源。
本申请实施例的第二方面，本申请实施例提供了一种资源指示方法。该方法应用于采用旁链路传输的过程中。该方法包括：接收端UE接收第一指示信息，该第一指示信息用于指示第一资源，该第一资源用于传输第一反馈信息；接收端UE在该第一资源上向目标设备发送该第一反馈信息，该目标设备包括发送端UE和控制节点中的至少一个。
本申请实施例的第三方面，本申请实施例提供了一种设备。该设备应用于采用旁链路传输的过程中。该设备可以包括确定单元和发送单元。确定单元，用于第一资源，该第一资源用于传输第一反馈信息；发送单元，用于向第二设备发送第一指示信息， 该第一指示信息用于指示第一资源。
本申请实施例的第四方面，本申请实施例提供了一种设备。该设备可以为接收端UE，该设备应用于采用旁链路传输的过程中。该设备可以包括接收单元和发送单元。接收单元，用于接收第一指示信息，该第一指示信息用于指示第一资源，该第一资源用于传输第一反馈信息；发送单元，用于在第一资源上向目标设备发送该第一反馈信息，该目标设备包括发送端UE和控制节点中的至少一个。
本申请实施例的第五方面，提供一种设备，该设备包括处理器、存储器及存储在存储器上并可在处理器上运行的计算机程序，该计算机程序被处理器执行时实现上述第一方面中的资源指示方法的步骤。
本申请实施例的第六方面，提供一种设备，该设备包括处理器、存储器及存储在存储器上并可在处理器上运行的计算机程序，该计算机程序被处理器执行时实现上述第二方面中的资源指示方法的步骤。
本申请实施例的第七方面，提供一种通信系统，该通信系统包括如第三方面中的设备，以及如第四方面中的设备；或者，该通信系统包括如第五方面中的设备，以及如第六方面中的设备。
本申请实施例的第八方面，提供一种计算机可读存储介质，该计算机可读存储介质上存储计算机程序，该计算机程序被处理器执行时实现如第一方面中的资源指示方法的步骤，或者如第二方面中的资源指示方法的步骤。
在本申请实施例中，采用旁链路传输的过程中，第一设备可以确定第一资源(该第一资源用于传输第一反馈信息)；并向第二设备发送第一指示信息(该第一指示信息用于指示第一资源)。通过该方案，由于第一设备可以确定用于承载反馈信息的传输资源(第一资源)，因此一种可能的情况是，如果第一设备为发送端UE，那么发送端UE还可以分配用于传输控制信息和/或业务数据的资源(第二资源)，从而可以避免用于传输控制信息和/或业务数据的资源与用于传输反馈信息的资源冲突；另一种可能的情况是，如果第一设备为控制节点，那么控制节点还可以为发送端UE分配用于传输控制信息和/或业务数据的资源(第二资源)，从而可以避免用于传输控制信息和/或业务数据的资源与用于传输反馈信息的资源冲突。如此，本申请实施例提供的资源指示方法，可以避免用于传输控制信息和/或业务数据的资源与用于传输反馈信息的资源冲突。

步骤203、第二设备接收该第一指示信息。
本申请实施例提供一种资源指示方法，由于第一设备可以确定用于承载反馈信息的传输资源(第一资源)，因此一种可能的情况是，如果第一设备为发送端UE，那么发送端UE还可以分配用于传输控制信息和/或业务数据的资源(第二资源)，从而可以避免用于传输控制信息和/或业务数据的资源与用于传输反馈信息的资源冲突；另一种可能的情况是，如果第一设备为控制节点，那么控制节点还可以为发送端UE分配用于传输控制信息和/或业务数据的资源(第二资源)，从而可以避免用于传输控制信息和/或业务数据的资源与用于传输反馈信息的资源冲突。如此，本申请实施例提供的资源指示方法，可以避免用于传输控制信息和/或业务数据的资源与用于传输反馈信息的资源冲突。
可选的，本申请实施例中，如果第一设备为发送端UE，第二设备为接收端UE，那么接收端UE可以接收发送端UE发送的第一指示信息；如果第一设备为控制节点，第二设备为发送端UE，那么发送端UE可以接收控制节点发送的第一指示信息，并向接收端UE转发该指示信息，从而接收端UE可以接收该指示信息；如果第一设备为控制节点，第二设备为接收端UE，那么接收端UE可以接收第一设备发送的第一指示信息。因此，本申请实施例提供的资源指示方法可以包括下述的步骤204和步骤205。
步骤204、接收端UE接收第一指示信息。

其中，上述目标设备可以包括发送端UE和控制节点中的至少一个。
相应的，目标设备(即发送端UE和控制节点)可以在第一资源上接收第一反馈信息。
本申请实施例提供的资源指示方法，由于接收端UE可以从控制节点或发送端UE接收指示用于承载反馈信息的传输资源(第一资源)的信息，因此接收端UE可以无需分配第一资源，从而可以避免用于传输控制信息和/或业务数据的资源(即第二资源)与第一资源冲突。
可选的，结合图2，如图3所示，本申请实施例提供的资源指示方法还可以包括下述的步骤206至步骤211。
步骤206、第一设备向第二设备发送第二指示信息。

示例性的，以第一设备为发送端UE，第二设备为接收端UE为例进行示例性说明。首先，发送端UE可以确定第一指示信息(该第一指示信息用于指示用于传输第一反馈信息的PSFCH-1资源)，并确定第二指示信息(该第二指示信息用于指示用于传输第一业务数据的PSSCH-1资源)，并通过将该第一指示信息和第二指示信息携带在SCI-1中向接收端UE发送，从而接收端UE可以接收并解调该SCI-1，获取该PSSCH-1资源和该PSFCH-1资源，并对该PSSCH-1资源上传输的数据进行解调，以及根据解调成功与否得到HARQ-ACK-1反馈信息。其次，发送端UE可以确定第三指示信息(该第三指示信息用于指示用于传输第二反馈信息的PSFCH-2资源)，并确定第四指示信息(该第四指示信息用于指示用于传输第二业务数据的PSSCH-2资源)，并通过将该第三指示信息和第四指示信息携带在SCI-2中向接收端UE发送，从而接收端UE可以接收并解调该SCI-2，获取该PSSCH-2资源和该PSFCH-2资源，并对该PSSCH-2资源上传输的数据进行解调，以及根据解调成功与否得到HARQ-ACK-2反馈信息。再次，接收端UE可以构造包括HARQ-ACK-1反馈信息和HARQ-ACK-2反馈信息的HARQ码本，并在PSFCH-1资源上向发送端UE传输SFCI信息(该SFCI信息包括该HARQ码本)，如此发送端UE可以根 据该HARQ码本确定业务数据是否传输成功，进而确定是否重发数据。

可以理解，通过在第一控制信道携带第一标识，在第二控制信道携带第二标识，接收端UE可以根据第一标识和第二标识确定各个信道的数据是否接收成功，以确定向发送端UE或控制节点发送何种反馈信息。
可选的，上述分配标示可以是数据(或数据包)的序号。例如，假设第二资源为PSSCH-1，第四资源为PSSCH-2，那么第一标识可以为序号1，第二标识可以为序号2。
可选的，上述分配标示可以用于指示第一设备已发送的数据(或数据包)数量。例如，如果第一标识为4，那么可以指示第一设备已发送的数据包数量为4。
可选的，上述分配标示可以用于指示第一设备总共发送的数据(或数据包)数量。例如，如果第一标识或第二标识为8，那么可以指示第一设备总共发送的数据包数量为8。
可选的，上述分配标示可以用于指示数据包为第一设备发送的第奇数个包或第偶数个包。示例性的，如果第一设备发送的第一个数据包的分配标示为1，可以指示该第一个数据包为第奇数个包；如果第一设备发送的第二个数据包的分配标示为0，可以指示该第二个数据包为第偶数个包；如果第一设备发送的第三个数据包的分配标示为1，可以指示该第三个数据包为第奇数个包；如果第一设备发送的第四个数据包的分配标示为0，可以指示该第四个数据包为第偶数个包。
本申请实施例提供的资源指示方法，在多个指示信息指示的资源的目标资源全部相同或部分相同的情况下，由于接收端UE可以把多个反馈信息复用在相同的资源上发送，因此可以提高通信系统的传输效率，并降低系统开销。
