Description

直连通信方法及装置 技术领域
本公开涉及通信领域，尤其涉及直连通信方法及装置。
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。
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。

在步骤102中，使用所述直连通信BWP集合进行直连通信。
本步骤中，直连通信设备在确定了直连通信BWP集合之后，可以使用直连通信BWP集合进行直连通信。
上述实施例中，直连通信设备可以确定直连通信部分带宽BWP集合，直连通信BWP集合中至少包括第一直连通信BWP和第二直连通信BWP，直连通信设备可以使用直连通信BWP集合进行直连通信。本公开实施例，可以让直连通信设备使用直连通信BWP集合进行直连通信，提高了直连通信的灵活性。
在一实施例中，直连通信设备可以基于基站指示动态确定直连通信BWP集合中的第一直连通信BWP和/或第二直连通信BWP，参照图2所示，图2是根据图1所示的实施例示出的另一种直连通信方法流程图，步骤101可以包括：
在步骤101-1中，接收基站发送的下行控制信令。
本步骤中，基站可以通过下行控制信令指示第一直连通信BWP、或第二直连通信BWP、或第一直连通信BWP和第二直连通信BWP对应的配置，直连通信设备按照相关技术接收下行控制信令。
在步骤101-2中，根据所述下行控制信令，确定所述直连通信BWP集合。
本步骤中，直连通信设备在接收到下行控制信令之后，可以根据下行 控制信令的指示，确定第一直连通信BWP和所述第二直连通信BWP中的至少一项。
上述实施例中，直连通信设备可以接收基站发送的下行控制信令，从而根据下行控制信令，确定直连通信BWP集合，实现了由基站为直连通信设备动态配置直连通信BWP集合的目的。
在一实施例中，参照图3所示，图3是根据图2所示的实施例示出的另一种直连通信方法流程图，步骤101-2可以包括：
在步骤101-21中，根据所述基站发送的小区广播消息，确定所述第一直连通信BWP。
本公开实施例中，基站可以通过不同的下行控制信令指示不同的直连通信BWP。其中，基站可以通过所有直连通信设备均需要接收的小区广播消息，指示第一直连通信BWP的配置信息。直连通信设备可以根据小区广播消息，确定第一直连通信BWP。
在步骤101-22中，根据所述基站发送的针对不同设备类型的直连通信设备的下行控制信息，确定所述第二直连通信BWP。
本步骤中，基站通过针对不同设备类型的直连通信设备发送对应的下行控制信息，该下行控制信息中指示不同设备类型的直连通信设备对应的第二直连通信BWP，直连通信设备接收到该下行控制信息之后，可以根据下行控制信息，确定与自身对应的第二直连通信BWP。
上述实施例中，直连通信设备可以根据基站发送的小区广播消息来确定直连通信集合中的第一直连通信BWP，另外还可以根据基站发送的针对不同设备类型的直连通信设备的下行控制信息，确定直连通信集合中的第二直连通信BWP，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直连通信方法流程图，步骤101-22可以包括：
在步骤101-221中，在所述下行控制信息指示的所述基站为所述不同设备类型的直连通信设备配置的多个BWP中，根据预设的直连通信设备 的设备类型和BWP之间的对应关系，确定与所述直接通信设备的设备类型对应的BWP。
本步骤中，基站可以通过下行控制信息为不同设备类型的直连通信设备配置的多个BWP。直连通信设备在基站配置的多个BWP中，可以根据预设的直连通信设备的设备类型和BWP之间的对应关系，确定与所述直连通信设备的设备类型对应的BWP。
例如，基站发送的下行控制信息中针对不同设备类型的直连通信设备配置了多个BWP，假设多个BWP中包括BWP1和BWP2。预设的直连通信设备的设备类型和BWP之间的对应关系为低能耗低成本的第一设备类型对应下行控制信息所指示的第一个BWP，大数据率低延迟的第二设备类型对应下行控制信息所指示的第二个BWP。
直连通信设备的设备类型为第一设备类型时，对应的BWP为BWP1，直连通信设备的设备类型为第二设备类型时，对应的BWP为BWP2。
在步骤101-222中，将与所述直接通信设备的设备类型对应的所述BWP作为所述第二直连通信BWP。
例如，与直接通信设备的设备类型对应的所述BWP为BWP1，则直接通信设备将BWP1直接作为第二直连通信BWP。
上述实施例中，直连通信设备可以根据预设的直连通信设备的设备类型和BWP之间的对应关系，在基站为不同设备类型的直连通信设备配置的多个BWP中，确定所述直接通信设备的设备类型对应的BWP，进一步地，将与所述直接通信设备的设备类型对应的所述BWP作为所述第二直连通信BWP，可用性高。在一实施例中，直连通信设备还可以基于预配置确定直连通信BWP集合中的第一直连通信BWP和/或第二直连通信BWP，相应地，步骤101可以包括：
在步骤101-3中，根据预配置给所述直连通信设备的BWP，确定所述第一直连通信BWP和/或所述第二直连通信BWP。
本公开实施例中，可以根据协议中预配置给该直连通信设备的BWP， 确定自身直连通信BWP集合中的第一直连通信BWP，或者第二直连通信BWP，或者第一直连通信BWP和第二直连通信BWP。
可选地，预配置给直连通信设备的BWP中可以明确指示分别属于第一直连BWP和第二直连BWP的BWP，还可以在预配置给直连通信设备的BWP中只指示用于该直连通信设备发送发现信号或寻呼信号的BWP，则该直连通信设备将发送设备发现信号或寻呼信号的BWP作为第一直连通信BWP，其他BWP作为第二直连通信BWP。
其中，设备发现信号用于广播该直连通信设备自身的设备标识和/或设备类型，寻呼信号用于寻呼其他直连通信设备，当然，寻呼信号中也可以包括该直连通信设备自身的设备标识和/或设备类型。
在一实施例中，假设存在两个不同设备类型的直连通信设备，设备1属于低能耗低成本的设备，设备2属于大数据率低延迟的设备，则设备1和设备2可以根据基站配置或预配置分别确定自身对应的第一直连通信BWP和第二直连通信BWP，例如图5所示。
其中，设备1和设备2的第一直连通信BWP相同，设备1的第二直连通信BWP为BWP1，是具备交底子载波间隔和较窄的带宽，设备2的第二直连通信BWP为BWP2，是具备较高子载波间隔和较宽的带宽。
在一实施例中，参照图6所示，图6是根据图1所示的实施例示出的另一种直连通信方法流程图，步骤102可以包括：
在步骤102-1中，使用所述第一直连通信BWP进行发送和/或接收直连通信广播信道、直连通信同步信号，发送和/或监听寻呼信号或设备发现信号，发送和/或监听与数据传输关联的直连控制信号中的至少一项。
本步骤中，直连通信设备可以使用第一直连通信BWP发送收直连通信广播信道和直连通信同步信号，或者接收直连通信广播信道和直连通信同步信号，从而与其他直连通信设备基于直连通信广播信道和直连通信同步信号进行直连通信同步。
直连通信设备还可以发送寻呼信号或设备发现信号，或者监听其他直 连通信设备发送的寻呼信号或设备发现信号，以便后续与其他直连通信设备进行直连通信。
直连通信设备还可以发送或监听与数据传输关联的直连控制信号，从而确定后续进行直连通信所使用的BWP。其中，该直连通知信号可以是物理层直连控制信号或者RRC(Radio Resource Control，无线资源控制)层直连控制信号。
例如，直连通信设备在第一直连通信BWP上发送物理层直连控制信息，该直连控制信息中包含对应的数据传输所使用的BWP的信息；另一直连通信设备在第一直连通信BWP上接收直连控制信息，并在直连控制信息所指示的BWP上接收直连数据。
通过上述过程，对于同时进行多种服务的直连通信设备而言，如果不同的服务使用的BWP不同，不用在所有服务对应的BWP上监听直连控制信息，只需要在第一直连通信BWP上监听，并及时切换到相应的BWP(第二直连通信BWP)上进行数据发送或接收即可，能够降低用户设备监听的能耗和成本。
再例如，直连通信设备作为单播或者组播的发送端，在第一直连通信BWP上发送RRC层的直连控制信息，其中包括进行单播或者组播通信使用的BWP信息，其他直连通信设备作为接收端，接收到直连控制信息后，同样在第一直连通信BWP上发送连接建立确认信息。接下来作为接收端的直连通信设备在之前指示的BWP上与作为发送端的直连通信设备进行单播或者组播通信即可，通信结束或通信一段时间后再回到第一直连通信BWP上进行通信。
在步骤102-2中，使用所述第二直连通信BWP进行数据发送和/或接收。
本步骤中，直连通信设备可以使用第二直连通信BWP进行数据发送和数据接收中的至少一项。
上述实施例中，直连通信设备可以使用第一直连通信BWP进行发送 和/或接收直连通信广播信道、直连通信同步信号，发送和/或监听寻呼信号或设备发现信号，发送和/或监听与数据传输关联的直连控制信号中的至少一项，使用第二直连通信BWP进行数据发送和/或接收。通过上述过程，可以让直连通信设备使用直连通信BWP集合中不同的直连通信BWP支持不同的服务，提高了直连通信的灵活性，有利于降低设备处理复杂度和设备能耗。
在一实施例中，如果同时运行多种服务的直连通信设备，需要同时((例如同一个Ts、OFDM符号、时隙、子帧等)发送或者接收多个BWP，且该直连通信设备不支持多个BWP的同时操作，则该直连通信设备可以按照不同服务的优先级顺序，选择优先级最高的服务对应的BWP进行发送或者接收。
其中，Ts是LTE(Long Term Evolution，长期演进)中最基本的时间单位，为1/(15000x2048)秒。
在一实施例中，直连设备的第一直连通信BWP和第二BWP可以使用相同或不同的子载波间隔、频域带宽和/或频域位置，可用性高。
下面再从基站侧介绍本公开实施例提供的直连通信方法。

本步骤中，基站可以动态为直连通信设备配置直连通信BWP集合中的第一直连信BWP和/或第二直连通信BWP，并通过下行控制信令将配置的第一直连信BWP和/或第二直连通信BWP告知直连通信设备。
上述实施例中，基站可以发送下行控制信令到直连通信设备，由直连通信设备根据下行控制信令，确定进行直连通信的直连通信BWP集合中的第一直连通信BWP和/或第二直连通信BWP，实现了由基站为直连通信 设备动态配置直连通信BWP集合的目的，提高了直连通信的灵活性。
在一实施例中，下行控制信令可以同时用于指示所述第一直连通信BWP和所述第二直连通信BWP，基站可以通过不同的下行控制信令对不同的直连通信BWP进行配置，其中，可以通过小区广播消息为直连通信设备配置第一直连通信BWP，通过针对不同设备类型的直连通信设备的下行控制信息为直连通信设备配置第二直连通信BWP，实现简便，可用性高。
