Description

资源分配方法及装置 技术领域
本发明涉及通信技术领域，尤其涉及一种资源分配方法及装置。
背景技术
车联网通信(V2x，Vehicle to Everything)是指将车辆与一切事物相连接的新一代信息通信技术，V2x包括车车互联通信(V2V，Vehicle to Vehicle)、车人互联通信(V2P，Vehicle to Pedestrian)及车路互联通(V2I，Vehicle to Infrastructure)。基于蜂窝网络的车联网通信(C-V2x，cellular based V2x)可以有效利用现有基站部署，减少设备开销，满足车联网业务的需求。在C-V2x中，车载设备和其他设备之间的通信可以通过基站以及核心网进行中转，即利用原有蜂窝网络中用户设备和基站之间的通信链路进行通信；也可以直接通过设备之间的直连链路(SL，Sidelink)进行直连通信。
而为了支持多种V2x业务的不同业务需求，并提供更高的通信速率，更短的通信延时，更可靠的通信质量，基于5G NR技术的车联网通信(NR V2x)技术的物理层需要支持单播和组播传输，并支持单播和组播传输的物理层混合自动重传请求(HARQ，Hybrid automatic repeat request)反馈机制。为了支持直连通信单播和组播的物理层HARQ，NR V2x中增加了直连物理反馈信道(PSFCH，Physical Sidelink Feedback channel)来传输HARQ反馈信息。而如何配置PSFCH的资源是需要解决的问题。

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发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
相关技术中，在C-V2x中，采用配置资源池的方式为各种直连信道，例如物理直连通信共享信道(PSSCH，Pysical Sidelink Share Channel)和物理直连通信控制信道(PSCCH，Pysical Sidelink Control Channel)分配时间频率资源。例如，针对PSSCH和PSCCH资源池配置信息可以包括：PSSCH和PSCCH资源池占用的子帧(subframe)的时域位置(PSSCH和PSCCH占用相同的时域资源)、PSSCH资源池的频域位置、及PSCCH资源池的频域位置。
但是，5G NR V2x为了支持直连通信单播和组播的物理层HARQ，增加了PSFCH信道来传输HARQ反馈信息。由于NR V2x需要支持对延时更加敏感的业务，PSFCH可以只占用一个时间单元的部分OFDM符号，以支持更加快速的反馈。但是，由于PSFCH和PSSCH及PSCCH的发送方向及接收方向均相反，用户设备可能需要在同一个时间单元内在发送和接收之间进行切换，需要留出足够的切换时间；另外，由于PSFCH的发送用户设备和PSSCH及PSCCH的发送用户设备不一样，造成其他用户设备在同一个时间单元内不同的OFDM时域符号上接收功率不一致，由于自动增益控制(AGC，Automatic gain control)线性范围的影响，可能需要一段时间用来调整AGC的工作点，即使其他用户设备使用同一时间单元的不同频域资源，也会造成接收性能下降。
为了解决上述问题，本发明实施例提供了一种资源分配方法，应用于用户设备，方法包括：接收基站发送的资源分配指示信息或者获取预配置的资源分配指示信息；其中，资源分配指示信息用于表征目标时间单元内用于直连通信的正向时频资源占用的时域资源和/或反向时频资源占用的时域资源；正向时频资源用于传输用户数据及控制信息，反向时频资源用于传输从用户数据的接收设备到用户数据的发送设备的反馈信息；根据资源分配指示信息， 确定正向时频资源占用的时域资源和/或反向时频资源占用的时域资源。本发明实施例提供的资源分配方法，通过将一个时间单元内的直连通信时频资源划分为正向时频资源和反向时频资源，采用时分复用(TDM)的方式进行复用，使用正向时频资源传输用户数据及控制信息，使用反向时频资源传输从用户数据的接收设备到用户数据的发送设备的反馈信息，这就能够保证在正向时频资源上接收的设备接收到的都是用户数据及控制信息，而在反向时频资源上接收的设备接收到的都是反馈信息，从而避免由于不同用户正向传输和反向传输切换时间不一致造成一次传输过程中不同时间符号上接收功率不一致的问题，改善设备接收性能，提高业务质量。
参见图1示出的本发明实施例中资源分配方法的一个可选的应用场景；图1所示的应用场景中涉及：第一设备11、第二设备12、蜂窝网络的基站13、基站14、及核心网15；其中，蜂窝网络可以是4G或5G网络；第一设备11与基站13通过空口16进行通信，第二设备12与基站14通过空口17进行通信；第一设备11和第二设备12之间的通信，可以通过基站13、基站14及核心网15进行中转，也可以直接通过设备之间的直连链路18进行直连通信。图1中示出的应用场景仅是本发明实施例记载的技术方案的一个可能的应用场景示例，其他应用场景可以包括图1未涉及的设备和网络；实际中，上述第一设备11和第二设备12也可以接入同一基站。
需要指出的是，本发明实施例提供的资源分配方法可以应用于V2x技术中；本公开实施例中涉及的用户设备，例如可以包括支持V2x直连通信的车载设备、手持设备及路边设备；手持设备，例如可以包括智能手机、平板电脑、台式机、笔记本电脑、无人机或穿戴式设备(如手环、智能眼镜等)等电子设备。
基于上述分析，提出以下各具体实施例。
图2是根据一示例性实施例示出的一种资源分配方法的流程图。本发明实施例中资源分配方法的执行主体可以为用户设备，如图2所示，该方法包括以下步骤201-202：
在步骤201中，接收基站发送的资源分配指示信息或者获取预配置的资源分配指示信息；其中，资源分配指示信息用于表征目标时间单元内用于直连通信的正向时频资源占用的时域资源和/或反向时频资源占用的时域资源；正向时频资源用于传输用户数据及控制信息，反向时频资源用于传输从用户数据的接收设备到用户数据的发送设备的反馈信息。
示例的，反馈信息可以包括以下任意一种信息或组合：HARQ反馈信息、或信道状态信息(CSI，Channel State Information)反馈信息。
示例的，用户设备可以接收基站发送的资源分配指示信息，或者，用户设备也可以使用预配置中的资源分配指示信息。例如预配置的资源分配指示信息可以存储在用户设备中，当用户设备处于蜂窝网覆盖范围外时，可以使用预配置的系统参数和配置信息进行通信。以用户设备接收基站发送的资源分配指示信息为例进行说明如下：基站在需要为直连通信中的PSSCH、PSCCH及PSFCH等直连信道分配时间频率资源时，可以根据预估的直连通信的用户数据、控制信息及反馈信息分别需要占用的时频资源大小，将目标时间单元内用于直连通信的 时频资源划分为正向时频资源和反向时频资源，正向时频资源和反向时频资源通过时分复用的方式进行复用，使用正向时频资源传输用户数据及控制信息，使用反向时频资源传输从用户数据的接收设备到用户数据的发送设备的反馈信息(例如HARQ反馈信息，CSI反馈信息等)。例如，将正向时频资源分配给PSSCH和PSCCH，用于PSSCH发送用户数据，及用于PSCCH发送控制信息，而将反向时频资源分配给PSFCH，用于PSFCH发送反馈信息。可选的，在目标时间单元内的正向时频资源所占用的时域资源是连续的，在目标时间单元内的反向时频资源所占用的时域资源也是连续的。
示例的，目标时间单元可以包括以下任意一种时间单位或组合：帧(frame)、子帧(subframe)、时隙(slot)、或时域符号(symbol)。下文中以slot作为时间单元，以symbol作为时域资源划分的最小单位进行举例说明，但是本发明并不排除其他可能性，比如以子帧或帧为时间单元，以slot为最小的时域资源单位进行分配的方式。
示例的，在步骤201中接收基站发送的资源分配指示信息的实现方式可以包括以下任意一种方式或组合：
方式A)接收基站发送的无线资源控制(RRC，Radio Resource Control)信令；其中，RRC信令中包括资源分配指示信息。通常RRC配置的是半静态或者静态信息，信息更新时间间隔以分钟、小时或天为单位。
方式B)接收基站发送的下行控制信息(DCI，Downlink Control Information)；其中，DCI中包括资源分配指示信息。通常DCI信令为动态信令，信息更新时间间隔以毫秒为单位。
可选的，本公开并不限定基站是否需要向用户设备指示正向时频资源和反向时频资源所占用的频域资源，可以默认正向时频资源和反向时频资源包括所有频域资源，也可以为正向时频资源和反向时频资源指定最低频域资源位置和频域资源宽度。
示例的，资源分配指示信息的实现方式可以包括以下任意一种方式或组合：
方式a)资源分配指示信息包括：第一资源指示信息和/或第二资源指示信息；其中，第一资源指示信息用于表征目标时间单元内用于直连通信的正向时频资源的时域资源长度；第二资源指示信息用于表征反向时频资源的时域资源长度。
示例的，在本实施例中，以时域符号作为时域资源划分的最小单位为例进行说明，目标时间单元由若干个时域符号组成。若目标时间单元内的所有时域资源都用作直连通信，则基站可以限定正向时频资源占用的时域符号的序号小于反向时频资源占用的时域符号的序号，即限定正向时频资源占用目标时间单元内位置靠前的时域符号，而反向时频资源占用目标时间单元内位置靠后的时域符号；且在基站向用户设备发送的资源分配指示信息中包括第一资源指示信息和/或第二资源指示信息，第一资源指示信息用于表征目标时间单元内用于直连通信的正向时频资源的时域资源长度，即指示正向时频资源占用的目标时间单元内的时域符号，第二资源指示信息用于表征反向时频资源的时域资源长度，即指示反向时频资源占用的目标时间单元内的时域符号。目标时间单元内处于正向时频资源和反向时频资源之间的时域符号可以用作保护间隔或其他用途。
方式b)资源分配指示信息包括：第三资源指示信息和/或第四资源指示信息；其中，第三资源指示信息，用于表征目标时间单元内用于直连通信的正向时频资源的起始时域资源位置和时域资源长度；第四资源指示信息，用于表征反向时频资源的起始时域资源位置和时域资源长度。
示例的，若目标时间单元内既存在用于直连通信的时域符号，也存在只用于基站和用户设备进行上下行通信的时域符号，则基站可以在向用户设备发送的资源分配指示信息中包括第三资源指示信息和/或第四资源指示信息，第三资源指示信息用于表征目标时间单元内用于直连通信的正向时频资源的起始时域资源位置和时域资源长度，即指示正向时频资源在目标时间单元内占用的起始时域资源位置和时域符号数目，第四资源指示信息用于表征反向时频资源的起始时域资源位置和时域资源长度，即指示反向时频资源在目标时间单元内占用的起始时域资源位置和时域符号数目。
方式c)资源分配指示信息包括：时域资源分配格式的标识，用于指示用户设备根据时域资源分配格式，确定正向时频资源占用的时域资源和/或反向时频资源占用的时域资源。
示例的，可以通过预先在通信协议中定义多个不同的时域资源分配格式，每个时域资源分配格式对应一种将一个时间单元内的直连通信时频资源划分为正向时频资源和反向时频资源的资源划分方式，并对每个时域资源分配格式分配标识，例如序号。预先将配置信息写入用户设备的静态或半静态存储器，其中，配置信息包括各个时域资源分配格式的标识、及不同的时域资源分配格式与不同的资源划分方式的对应关系。
基站根据预估的直连通信的用户数据、控制信息及反馈信息分别需要占用的物理资源大小，确定将目标时间单元内用于直连通信的时频资源划分为正向时频资源和反向时频资源的资源划分方式，并从上述配置信息中获知与资源划分方式对应的时域资源分配格式，然后基站在下行动态指示信令(例如DCI)中携带时域资源分配格式的标识，通过时域资源分配格式的标识，指示用户设备使用与时域资源分配格式对应的资源划分方式。
在步骤202中，根据资源分配指示信息，确定正向时频资源占用的时域资源和/或反向时频资源占用的时域资源。
用户设备根据资源分配指示信息，确定正向时频资源占用的时域资源和/或反向时频资源占用的时域资源；然后在正向时频资源上传输用户数据及控制信息，而在反向时频资源上传输从用户数据的接收设备到用户数据的发送设备的反馈信息。
示例的，可以将正向时频资源和反向时频资源之间的时域资源确定为保护间隔；其中，保护间隔占用的时域资源，用于为用户设备提供用于切换传输方向的时间，从而为用户设备提供用于切换传输方向的时间，避免由于不同用户正向传输和反向传输切换时间不一致造成一次传输过程中不同时间符号上接收功率不一致的问题。
采用本发明实施例提供的技术方案，通过将一个时间单元内的直连通信时频资源划分为正向时频资源和反向时频资源，采用时分复用的方式进行复用，使用正向时频资源传输用户数据及控制信息，使用反向时频资源传输从用户数据的接收设备到用户数据的发送设备的反 馈信息，这就能够保证在正向时频资源上接收的设备接收到的都是用户数据及控制信息，而在反向时频资源上接收的设备接收到的都是反馈信息，从而避免由于不同用户正向传输和反向传输切换时间不一致造成一次传输过程中不同时间符号上接收功率不一致的问题，改善设备接收性能，提高业务质量。
图3是根据一示例性实施例示出的一种资源分配方法的流程图。本发明实施例中资源分配方法的执行主体可以为蜂窝网络的基站，如图3所示，该方法包括以下步骤301-302：
在步骤301中，将目标时间单元内用于直连通信的时频资源划分为时分复用的正向时频资源和反向时频资源；其中，正向时频资源用于传输用户数据及控制信息，反向时频资源用于传输从用户数据的接收设备到用户数据的发送设备的反馈信息。
示例的，目标时间单元可以包括以下任意一种时间单位或组合：帧、子帧、时隙、或时域符号。反馈信息可以包括以下任意一种信息或组合：HARQ反馈信息、或CSI反馈信息。
示例的，基站在需要为直连通信中的PSSCH、PSCCH及PSFCH等直连信道分配时间频率资源时，可以根据预估的直连通信的用户数据、控制信息及反馈信息分别需要占用的物理资源大小，将目标时间单元内用于直连通信的时频资源划分为正向时频资源和反向时频资源，正向时频资源和反向时频资源通过时分复用的方式进行复用，使用正向时频资源传输用户数据及控制信息，使用反向时频资源传输从用户数据的接收设备到用户数据的发送设备的反馈信息(例如HARQ反馈信息，CSI反馈信息等)。例如，将正向时频资源占用的时域资源分配给PSSCH和PSCCH，用于PSSCH发送用户数据，及用于PSCCH发送控制信息，而将反向时频资源占用的时域资源分配给PSFCH，用于PSFCH发送反馈信息。可选的，在目标时间单元内的正向时频资源所占用的时域资源是连续的，在目标时间单元内的反向时频资源所占用的时域资源是连续的。

可选的，本公开并不限定基站是否需要向用户设备指示正向时频资源和反向时频资源所占用的频域资源，可以默认正向时频资源和反向时频资源包括所有频域资源，也可以为正向时频资源和反向时频资源指定最低频域资源位置和频域资源宽度。
示例的，资源分配指示信息的实现方式可以包括以下任意一种方式或组合：
方式a)资源分配指示信息包括：第一资源指示信息和/或第二资源指示信息；其中，第一资源指示信息，用于表征目标时间单元内用于直连通信的正向时频资源的时域资源长度；第二资源指示信息，用于表征反向时频资源的时域资源长度。
示例的，在本实施例中，以时域符号作为时域资源划分的最小单位表示时域资源为例进行说明，目标时间单元由若干个时域符号组成。若目标时间单元内的所有时域符号都用作直连通信，则基站可以限定正向时频资源占用的时域符号的序号小于反向时频资源占用的时域符号的序号，即限定正向时频资源占用目标时间单元内位置靠前的时域符号，而反向时频资源占用目标时间单元内位置靠后的时域符号；且在基站向用户设备发送的资源分配指示信息中包括第一资源指示信息和/或第二资源指示信息，第一资源指示信息用于表征目标时间单元内用于直连通信的正向时频资源的时域资源长度，即指示正向时频资源占用的目标时间单元内的时域符号，第二资源指示信息用于表征反向时频资源的时域资源长度，即指示反向时频资源占用的目标时间单元内的时域符号。目标时间单元内处于正向时频资源和反向时频资源之间的时域符号可以用作保护间隔或其他用途。
方式b)资源分配指示信息包括：第三资源指示信息和/或第四资源指示信息；其中，第三资源指示信息，用于表征目标时间单元内用于直连通信的正向时频资源的起始时域资源位置和时域资源长度；第四资源指示信息，用于表征反向时频资源的起始时域资源位置和时域资源长度。
示例的，若目标时间单元内既存在用于直连通信的时域符号，也存在只用于基站和用户设备进行上下行通信的时域符号，则基站可以在向用户设备发送的资源分配指示信息中包括第三资源指示信息和第四资源指示信息，第三资源指示信息用于表征目标时间单元内用于直连通信的正向时频资源的起始时域资源位置和时域资源长度，即指示正向时频资源在目标时间单元内占用的起始时域资源位置和时域符号数目，第四资源指示信息用于表征反向时频资源的起始时域资源位置和时域资源长度，即指示反向时频资源在目标时间单元内占用的起始时域资源位置和时域符号数目。
方式c)资源分配指示信息包括：时域资源分配格式的标识，用于指示用户设备根据时域资源分配格式，确定正向时频资源占用的时域资源和/或反向时频资源占用的时域资源。
示例的，可以通过预先在通信协议中定义多个不同的时域资源分配格式，每个时域资源分配格式对应一种将一个时间单元内的直连通信时频资源划分为正向时频资源和反向时频资源的资源划分方式，并对每个时域资源分配格式分配标识，例如序号。预先将配置信息写入用户设备的静态或半静态存储器，其中，配置信息包括各个时域资源分配格式的标识、及不同的时域资源分配格式与不同的资源划分方式的对应关系。
图4示出了一种时域资源分配格式所对应的资源划分方式，图4中序号为n的时域资源分配格式所对应的资源划分方式为：正向时频资源占用时间单元内的时域符号3至时域符号9，用于传输从数据发送设备到数据接收设备的用户数据及控制信息；而反向时频资源占用时 间单元内的时域符号11和时域符号12，用于传输从数据接收设备到数据发送设备的反馈信息；x表示不能被直连通信使用的时域符号，时域符号x可能用于上下行通信、保护间隔、或者其他用途。
基站根据预估的直连通信的用户数据、控制信息及反馈信息分别需要占用的物理资源大小，确定将目标时间单元内用于直连通信的时频资源划分为正向时频资源和反向时频资源的资源划分方式，并从上述配置信息中获知与资源划分方式对应的时域资源分配格式，然后基站在下行动态指示信令(例如DCI)中携带时域资源分配格式的标识，通过时域资源分配格式的标识，指示用户设备使用与时域资源分配格式对应的资源划分方式。
采用本发明实施例提供的技术方案，通过将一个时间单元内的直连通信时频资源划分为正向时频资源和反向时频资源，采用时分复用的方式进行复用，使用正向时频资源传输用户数据及控制信息，使用反向时频资源传输从用户数据的接收设备到用户数据的发送设备的反馈信息，这就能够保证在正向时频资源上接收的设备接收到的都是用户数据及控制信息，而在反向时频资源上接收的设备接收到的都是反馈信息，从而避免由于不同用户正向传输和反向传输切换时间不一致造成一次传输过程中不同时间符号上接收功率不一致的问题，改善设备接收性能，提高业务质量。

在步骤502中，将正向时频资源和反向时频资源之间的时域资源确定为保护间隔；其中，保护间隔占用的时域资源，用于为用户设备提供用于切换传输方向的时间。
示例的，当在正向时频资源和反向时频资源之间不存在用于上行和/或下行通信的时域资源时，在正向时频资源和反向时频资源之间设置时域的保护间隔，保护间隔用以提供切换传输方向的时间，即切换接收方向与发送方向的时间。当正向时频资源和反向时频资源占用时域上不连续的时频资源时，处于正向时频资源和反向时频资源之间的时频资源就可以在作为保护间隔的同时，还可以用于上行和/或下行通信。需要说明的是，保护间隔既不占用正向时频资源，也不占用反向时频资源，保护间隔占用目标时间单元内处于正向时频资源和反向时频资源之间的时域符号。可选的，用户设备在保护间隔内的行为可以不做规范。保护间隔可以由基站为用户设备进行配置，或者可以预先将保护间隔的配置信息写入用户设备的静态或半静态存储器。
图6a和图6b示出了一种资源分配方式，在图6a和图6b中，正向时频资源占用一个时隙内的前十个时域符号，反向时频资源占用一个时隙内第十二个和第十三个时域符号，保护间隔占用一个时隙内第十一个和第十四个时域符号；正向时频资源占用的时域资源用于传输 从数据发送设备到数据接收设备的用户数据及控制信息，反向时频资源占用的时域资源用于传输从数据接收设备到数据发送设备的反馈信息，保护间隔占用的时域资源用于为用户设备提供切换传输方向的时间。

在步骤503中，向用户设备发送资源分配指示信息；其中，资源分配指示信息用于表征目标时间单元内用于直连通信的正向时频资源占用的时域资源和/或反向时频资源占用的时域资源。
