Abstract

本公开提供一种确定频域资源的方法及装置，其中，所述方法包括：确定直连通信的接收端设备的目标设备类型；根据所述目标设备类型，确定与所述接收端设备进行直连通信时所使用的目标频域资源。本公开即使为不同类型的直连通信设备配置了不同的频域资源，仍可以确保第一类型直连通信设备与接收端设备的直连通信。

Description

确定频域资源的方法及装置 技术领域
本公开涉及通信领域，尤其涉及确定频域资源的方法及装置。
背景技术
NR(New Radio，新空口)系统的上下行设计中引入了BWP(BandWidth Part，部分带宽)，一个BWP指在给定载波频率上给定子载波间隔下的连续频域RB(Resource Block，资源块)。在NR上下行通信中BWP是针对每个设备配置的，并分为发送BWP和接收BWP。在一个载波频率上，每个设备可以被配置多个发送和接收BWP，但在同一时间只能激活其中一个BWP，并可以根据基站侧的下行信令指示进行动态或者半静态的BWP切换。设备只需要在激活的BWP内监听下行控制信令，也只能在激活的BWP内进行上行传输。
对于V2x(vehicle to everything，车联网)的车载设备而言，由于需要满足的车与车之间通信数据吞吐量要求较高，一般配置较宽的BWP。每个设备需要在BWP的资源池内对其他设备发送的SCI(Sidelink Control Information，直连控制信息)进行盲检测，另外还需要对其他设备发送的SCI中包含的资源占用等信息进行接收，并对其他设备的直连控制或数据发送进行测量，以避免可能的传输碰撞。这些操作使得用户设备的处理复杂度和能耗都较高。

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。
在本公开使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开。在本公开和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
NR Rel-16(版本16)讨论的V2x技术主要关注车和车之间的通信和服务。由于车载蓄电池的存在，不需要考虑车载终端的节能问题。在NR V2x Rel16中，定义了用户设备进行直连通信发送和接收使用的直连通信BWP。为了保证相同任意用户之间可以收发数据，发送和接收数据使用相同的BWP，每个车联网用户只能被配置一个直连通信BWP，并假设所有的车联网用户设备被配置的BWP相同。
在V2x系统中包括V2P(vehicle-to-pedestrian，车与人)，这里的人可以是为慢速易损伤道路参与者的统称，包括行人，自行车，滑板车等，统称P用户，P用户的通信设备包括手持设备。这些设备使用易携带的锂电池，对于设备能耗相对敏感。另外手持设备的体积和成本限制也较高，因此需要考虑这些终端的节电和复杂度问题。
在本公开实施例中，为了解决上述问题，在V2x直连通信系统中，可以根据不同的设备类型，为直连通信设备配置不同的直连通信BWP。
对于有节能需求的直连通信设备例如手持终端设备，统一配置一个相对于其他没有节能需求的车载设备而言带宽较窄的BWP。
假设为需节能手持设备配置的BWP为BWP1，为普通车载设备配置的BWP为BWP2。例如图1所示，BWP1和BWP2可以相同的子载波间隔，BWP1所占据的频域资源为BWP2所占据的频域资源的子集，且在BWP1上配置的直连通信资源池中的资源簇是BWP2上配置的直连通信资源池中的资源簇的子集合。
其中，资源簇为直连通信数据传输频域资源分配的最小的单位，BWP、资源池和资源簇之间的关系例如图2所示。
当配置BWP2的直连通信设备需要向配置BWP1的直连通信设备发送数据时，用于发送的频率资源应该属于BWP1上配置的资源池，这样配置BWP1的直连通信设备也可以接收到配置BWP2的直连通信设备发送的数据。
在本公开实施例中，可以在BWP2上配置用于向使用BWP1的直连通信设备发送直连通信信息的资源池，从而限制配置了BWP2的直连通信设备的资源选择。也就是说，配置了BWP2的直连通信设备，当需要发送直连通信数据到配置了BWP1的直连通信设备时，需要选择与BWP1资源池对应的时间频率资源进行发送。
基于上述配置，本公开实施例提供了一种确定频域资源的方法，下面先从第一类型直连通信设备侧进行介绍。
参照图3所示，图3是根据一实施例示出的一种确定频域资源的方法流程图，该方法可以用于第一类型直连通信设备，可选地，所述第一类型直连通信设备可以是对能耗要求较低的设备，例如车载设备等，该方法可以包括以下步骤：
在步骤101中，确定直连通信的接收端设备的目标设备类型。
本步骤中，直连通信设备可以通过与接收端设备的交互，确定接收端设备的目标设备类型。
例如，在与接收端设备进行直连通信的过程中，接收端设备通过设备发现信号或寻呼信号将自身的目标设备类型已经发送给直连通信设备，直连通信设备可以直接确定该接收端设备的目标设备类型。
在步骤102中，根据所述目标设备类型，确定与所述接收端设备进行直连通信时所使用的目标频域资源。
本步骤中，直连通信设备根据不同的目标设备类型，来确定与接收端设备进行直连通信时所使用的目标频域资源。
上述实施例中，第一类型直连通信设备可以根据直连通信的接收端设备的目标设备类型，确定与该接收端设备进行直连通信时所使用的目标频域资源。这样即使为不同类型的直连通信设备配置了不同的频域资源，仍可以确保第一类型直连通信设备与接收端设备的直连通信。
在一实施例中，针对上述步骤102，直连通信设备可以在确定所述目标设备类型中包括至少一个第二类型直连通信设备时，确定与所述第二类型直连通信设备进行直连通信时所使用的目标频域资源。
在本公开实施例中，第二类型直连通信设备可以是进入节能状态的第一类型直连通信设备，即某个直连通信设备可以在两个状态之间进行转换，如果未进入节能状态，则属于第一类型直连通信设备，进入节能状态，则属于第二类型直连通信设备。例如，车载设备在插电时属于第一类型直连通信设备，不插电时属于第二类型直连通信设备。
或者，第二类型直连设备还可以是设备类型不同于第一类型直连通信设备，且能耗要求高的直连通信设备，例如第一类型直连通信设备为插电的车载设备，第二类型直连通信设备为不插电的手持设备。
上述实施例中，第一类型直连通信设备可以在确定目标设备类型中包括至少一个第二类型直连通信设备时，根据目标设备类型，确定与第二类型直连通信设备进行直连通信时所使用的目标频域资源。其中，第二类型直连通信设备可以是进入节能状态的第一类型直连通信设备，或者所述第二类型直连通信设备还可以是设备类型不同于所述第一类型直连通信设备 的直连通信设备。可用性更高。
在一实施例中，可以采用以下方式中的任一种确定目标设备类型中包括所述第二类型直连通信设备。
第一种方式，根据接收端设备的设备标识和/或目的地址。
如果第一类型直连设备确定接收端设备的设备标识为预先指定的所述第二类型直连通信设备的设备标识，则可以确定所述目标设备类型中包括所述第二类型直连通信设备。
如果第一类型直连设备确定接收端的目的地址为预先指定的所述第二类型直连通信设备的目的地址，例如预先指定第二类型直连通信设备的目的地址属于某个IP地址段，如果第一类型直连设备确定接收端的目的地址属于预设IP地址段，则可以确定所述目标设备类型中包括所述第二类型直连通信设备。
第二种方式，根据高层信令的指示。
本公开实施例中，高层信令可以是应用层信令，第一类型直连通信设备可以接收高层发送给MAC(Media Access Control Address，媒体访问控制)层或物理层的信令，如果该信令指示接收端设备中包括所述第二类型直连通信设备，那么第一类型直连设备可以确定所述目标设备类型中包括所述第二类型直连通信设备。
第三种方式，根据接收端设备发送的控制信息。
本公开实施例中，如果直连通信设备在与接收端设备建立单播或组播通信过程中，接收端设备发送控制信息给该第一类型直连设备，该控制信息指示接收端设备为第二类型直连设备，那么第一类型直连设备可以确定所述目标设备类型中包括所述第二类型直连通信设备。
例如，控制信息中携带了接收端设备所使用的BWP的信息，该BWP是分配给第二类型直连设备使用的，此时第一类型直连设备可以确定目标设备类型中包括所述第二类型直连通信设备。
上述实施例中，第一类型直连通信设备可以根据接收端设备的设备标 识和/或目的地址、或者高层信令、或者接收端设备发送的控制信息中的任一项，来确定目标设备类型中是否包括第二类型直连通信设备，实现简便，可用性高。
在一实施例中，参照图4所示，图4是根据图3所示的实施例示出的另一种确定频域资源的方法流程图，步骤102可以包括：

在步骤102-2中，在第一频率资源范围中，确定所述目标频域资源。
本步骤中，第一类型直连设备在第一频率资源范围中，确定出进行直连通信的目标频域资源，后续通过目标频域资源发送和/或接收直连数据。
上述实施例中，第一类型直连通信设备可以先确定与所述第二类型直连通信设备进行直连通信时，自身所使用的第一频域资源范围，进一步地，在第一频域资源范围内，确定目标频域资源，在第一类型直连通信设备与第二类型直连通信设备配置了不同的频域资源时，实现第一类型直连通信设备与第二类型直连通信设备之间的直连通信，实现简便，可用性高。
在一实施例中，可以采用以下方式中的任意一种确定第一频域资源范围。
第一种方式，将预配置的频域资源范围作为所述第一频域资源范围。
第一直连通信设备直接可以在第一直连通信设备所对应的直连通信资源池中，将协议中预先配置好的频域资源范围作为第一频域资源范围。
通过上述过程，可以让第一类型直连通信设备根据预配置快速确定第一频域资源范围，可用性高。
第二种方式，根据基站指示确定第一频域资源范围。
参照图5所示，图5是根据图4所示的实施例示出的另一种确定频域 资源的方法流程图，步骤102-1可以包括：
在步骤102-11中，接收基站发送的下行控制信令。
在步骤102-12中，将所述下行控制信令所指示的频域资源范围作为所述第一频域资源范围。
本步骤中，第一直连通信设备可以将基站发送的下行控制信令中所指示的频域资源范围作为所述第一频域资源范围。
上述实施例中，可以让第一类型直连通信设备根据基于基站指示快速确定第一频域资源范围，可用性高。
第三种方式，将与所述第二类型直连通信设备使用的部分带宽BWP的频域资源重合的频域资源作为所述第一频域资源范围。
例如图6所示，基站预先为第二类型直连通信设备配置了第二类型直连通信设备使用的部分带宽BWP的频域资源，或者协议中预配置了第二类型直连通信设备使用的部分带宽BWP的频域资源，第一类型直连设备将与所述第二类型直连通信设备使用的部分带宽BWP的频域资源重合的频域资源直接作为所述第一频域资源范围。
上述实施例中，第一类型直连通信设备还可以将与所述第二类型直连通信设备使用的部分带宽BWP的频域资源重合的频域资源作为所述第一频域资源范围，同样可以快速确定第一频域资源范围，可用性高。
在本实施例中，如果第二类型直连通信设备可以是进入节能状态的第一类型直连通信设备，可以不单独为第二类型直连通信设备配置对应的直连通信资源池。下面从第二类型直连通信设备侧介绍本公开实施例提供的确定频域资源的方法，其中，第二类型直连通信设备是进入节能状态的第一类型直连通信设备。
参照图7所示，图7是根据一实施例示出的另一种确定频域资源的方法流程图，该方法可以用于第二类型直连通信设备，所述第二类型直连通信设备可以是进入节能状态的第一类型直连通信设备，该方法可以包括以下步骤：
在步骤201中，在第一类型通信设备使用的直连通信资源池内，确定目标资源簇集合。
其中，目标资源簇集合位于所述第二类型直连通信设备使用的部分带宽BWP的频域资源范围内。
例如图8所示，第二类型直连设备在第一类型通信设备使用的直连通信资源池内，确定出位于第二类型直连通信设备的部分带宽BWP的频率资源范围内的目标资源簇集合，目标资源簇集合对应图8中黑框圈出的资源簇。
在步骤202中，将所述目标资源簇集合作为所述第二类型直连通信设备的直连通信资源池。
本步骤中，第二类型直连通信设备可以直接将上述步骤201确定的资源簇集合作为所述第二类型直连通信设备的直连通信资源池，同样如图8所示。
上述实施例中，如果第二类型直连设备为进入节能状态的第一类型直连通信设备，那么无需单独为第二类型直连设备分配新的直连通信资源池，第二类型直连设备可以在第一类型通信设备使用的直连通信资源池内确定自身的直连通信资源池。
