Description

调度方法、设备与计算机可读存储介质
本申请要求于2018年09月20日提交中国专利局、申请号为2018111031444、申请名称为“调度方法、设备与计算机可读存储介质”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
本申请涉及通信领域，并且更具体地，涉及一种调度方法、设备与计算机可读存储介质。
背景技术
在5G通信场景中，终端设备通常需要获取网络设备分配的上行资源之后再进行上行业务的传输。
现有的网络设备为终端设备调度资源的方法通常为配置调度与动态调度。配置调度是网络设备为终端设备一次性地配置具有周期性的上行资源，但在终端设备侧的业务的到达时刻与上行资源的出现时刻不匹配的情况下会导致时延抖动。而动态调度需要网络设备需要根据终端设备发送的调度请求(scheduling request，SR)以及缓存状况报告(buffer state report，BSR)为终端设备分配上行资源，导致每次数据到达时终端设备均需要向网络设备发送SR与BSR，导致通信时延增大。
发明内容
本申请提供一种调度方法与设备，能够减少通信过程中上行业务的传输时延。
第一方面，提供了一种调度方法，包括：终端设备向网络设备发送第一信息，所述第一信息包括所述终端设备的上行业务的模式信息；所述终端设备接收所述网络设备发送的第二信息，所述第二信息用于指示所述上行业务被配置的上行资源；所述终端设备利用所述上行资源向所述网络设备传输所述上行业务。
上行业务可以具有一定的周期性，此时终端设备向网络设备上报的模式信息可以是与上行业务周期相关的信息；上行业务还可以不具备周期性，但是多个上行业务可以组成一个传输模式，或者说多个上行业务之间的时间间隔是固定的。从整个时域上看，上行业务可以具有多个传输模式，每个传输模式可以在时域上重复出现，且出现的时刻可以是具有规律的也可以是不具规律的。此时终端设备向网络设备上报的模式信息可以与传输模式相关的信息。或者上行业务不符合上述情况，但是终端设备可以预估将要进行的多个上行业务的到达时刻，则终端设备向网络设备上报的信息还可以包括该多个上行业务到达时刻的信息。或者模式信息也可以理解为业务在时域上出现时刻的排列所形成的形状等等。
应理解，上述模式信息可以包含上行业务的模式信息还可以包括上行业务数据包的大小信息。
上述技术方案中，终端设备提前向网络设备发送上行业务的模式信息，可以作为上行资源调度的参考，辅助网络设备更好地完成资源调度。

第一信息中的上行业务的起始时刻，可以是上行业务中第一个业务的到达时刻，能够帮助网络设备确认为上行业务配置的上行资源在何时出现。当然上行业务的起始时刻也可以是上行业务中的任一上行业务的到达时刻，本申请实施例对此不做具体限定。第一信息中的第一周期信息可以指示周期性上行业务的周期，时间偏移信息用于指示每个周期内多个上行业务之间的时间间隔，当然如果一个周期内只包含一个上行业务，第一信息中可以不携带时间偏移信息，或者时间偏移信息为0。第一信息中的第一差值信息的存在，指示了终端的上行资源与上行业务之间不匹配，可以通过上报第一差值帮助网络设备校正已经配置好的上行资源的出现时刻。
终端设备向网络设备上报上行业务的模式信息，便于网络设备根据上行业务的到达时刻为终端设备配置上行资源，或者调整已经配置好的上行资源，减少传输时延。
结合第一方面，在第一方面的某些实现方式中，所述模式信息为位图信息，所述位图信息包含多个比特位，所述比特位上的每个比特位对应一个时间单元，所述比特位对应的值为1或者0，所述值为1或者为0的比特位用于指示每个时间单元内是否有上行业务。
位图信息的长度可以代表周期长度，时间偏移信息可以用具有上行业务的时间单元与周期边界之间的时间单元的时间间隔来表示。使用位图信息指示模式信息可以理解为隐式的指示。
结合第一方面，在第一方面的一些实现方式中，第一信息还包括索引信息，所述索引信息用于指示以下信息中的至少一种：所述上行业务的模式信息，所述上行业务数据包的大小。

终端设备向网络设备报告上行业务数据包的大小或者上行业务与上行资源之间的差值，使得网络设备可以根据上行业务数据包的大小合理的分配上行资源。

当上行业务具有周期性时，网络设备为终端设备配置与上行业务周期相匹配的上行资源，进一步减少上行业务的传输时延。
结合第一方面，在第一方面的某些实现方式中，所述第二信息中包含所述上行业务的传输模式，所述上行业务的传输模式用于指示所述上行业务到达时刻和/或所述上行业务数据包的大小。
结合第一方面，在第一方面的某些实现方式中，所述第二信息中包含所述第一差值信息，所述第一差值信息用于调整已经配置好的上行资源出现的时刻。
应理解，第一差值信息用于调整已经配置好的资源相对原来出现时域位置的偏差和/或偏差的方向。网络设备可以根据终端设备上报的业务时刻与资源时刻之间的差值调整被配置的上行资源，完成上行资源出现时刻与上行业务到达时刻的同步。
结合第一方面，在第一方面的某些实现方式中，所述第二信息中包含所述第二差值信息，所述第二差值信息用于调整已经配置好的上行资源与大小。
网络设备可以根据终端设备上报的上行业务数据包的大小与资源时刻之间的差值调整被配置的上行资源，使得上行资源大小与上行业务数据包的大小的匹配。
结合第一方面，在第一方面的某些实现方式中,触发所述终端发送所述第一信息的条件为以下条件中的至少一种：所述终端设备检测到当前上行业务的到达时刻与当前上行资源的出现时刻之间的差值大于第一阈值；或所述终端设备的定时器超时；或所述终端设备检测到当前上行业务数据包的大小与当前上行资源大小之间的差值大于第二阈值。
终端设备可以在上行资源与上行业务的到达时刻不匹配时，或者资源大小不匹配时或者定时器超时时，向网络设备上报第一信息，网络设备可以根据第一信息调整已经配置的上行资源，或者直接根据第一信息配置上行资源。
应理解，所述终端设备可以通过无线资源控制层(radio resource control，RRC)信令，或媒体接入控制层控制元素(media access control layer control element，MAC CE)上报第一信息，其中MAC CE可以是BSR，也可以是单独设计的专用MAC CE。终端设备还可以通过其他的控制协议数据单元(protocol data unit，PDU)上报第一信息，本申请实施例对此不做具体限定。

具体实施方式
在一些通信场景下，终端设备在传输上行业务之前需要获得网络设备为其分配的上行资源，这一过程称为资源的调度过程。
常见的资源调度的方法为配置调度与动态调度，其中配置调度为网络设备直接一次性地为终端设备配置上行资源，终端设备周期性地使用上行资源，在上行业务周期改变或者发生时延的情况下，会造成时延抖动。在动态调度中，每次有上行业务到达时，终端设备向网络设备发送SR请求，向网络设备请求上行资源，网络设备根据SR请求终端设备配置固定大小的资源之后，终端设备再向网络设备发送BSR请求，基站根据BSR请求为基站分配大小合适的上行资源。动态配置每次上行业务到达都需发送资源请求，易造成传输时延。在一些应用场景下，例如工业应用场景，终端设备的上行业务在一定的时间内符合一定的规律，且对上行业务的时延要求以及时延抖动要求较高，上述调度方法将不再适用。
本申请实施例提供一种资源调度的方法，能够降低上行业务的传输时延。下面将结合附图，对本申请中的技术方案进行描述。
应理解，本申请实施例的技术方案可以应用于长期演进(long term evolution，LTE)架构，还可以应用于通用移动通信系统(universal mobile telecommunications system，UMTS)陆地无线接入网(UMTS terrestrial radio access network，UTRAN)架构，或者全球移动通信系统(global system for mobile communication，GSM)/增强型数据速率GSM演进(enhanced data rate for gsm evolution，EDGE)系统的无线接入网(GSM EDGE radio  access network，GERAN)架构。在UTRAN架构或/GERAN架构中，MME的功能由服务通用分组无线业务(general packet radio service，GPRS)支持节点(serving GPRS support，SGSN)完成，SGW\PGW的功能由网关GPRS支持节点(gateway GPRS support node，GGSN)完成。本申请实施例的技术方案还可以应用于其他通信系统，例如公共陆地移动网络(public land mobile network，PLMN)系统，甚至未来的5G通信系统或5G之后的通信系统等，本申请实施例对此不作限定。
本申请实施例涉及终端设备。终端设备可以为包含无线收发功能、且可以与网络设备配合为用户提供通讯服务的设备。具体地，终端设备可以指用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。例如，终端设备可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络或5G之后的网络中的终端设备等，本申请实施例对此不作限定。
本申请实施例还涉及网络设备。网络设备可以是用于与终端设备进行通信的设备，例如，可以是GSM系统或CDMA中的基站(base transceiver station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(evolutional NodeB，eNB或eNodeB)，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络或5G之后的网络中的网络侧设备或未来演进的PLMN网络中的网络设备等。
本申请实施例中涉及的网络设备也可称为无线接入网(radio access network，RAN)设备。RAN设备与终端设备连接，用于接收终端设备的数据并发送给核心网设备。RAN设备在不同通信系统中对应不同的设备，例如，在2G系统中对应基站与基站控制器，在3G系统中对应基站与无线网络控制器(Radio Network Controller，RNC)，在4G系统中对应演进型基站(Evolutional Node B，eNB)，在5G系统中对应5G系统，如新无线接入系统(New Radio Access Technology，NR)中的接入网设备(例如gNB，CU，DU)
为了便于理解，下面以5G新无线(new radio,NR)系统为例，说明本申请实施例的应用场景。图1是本申请实施例应用的一个场景，参考图1：
核心网设备140，可以包括接入和移动性管理功能(access and mobility management function，AMF)，会话管理功能(session management function，SMF)，统一数据管理网元(unified data management，UPF)等网络功能。核心网设备140通过S1接口分别与第一网络设备120与第二网络设备130连接，其中第一网络设备120与第二网络设备130组成该框架的无线部分。作为一个示例，本申请实施例的第一网络设备与第二网络设备可以均为gNB，二者之间通过X2接口进行通信。终端设备110可以向第一网络设备120或者第二网络设备130传输上行业务。
下面以上述网络架构为例说明配置调度与动态调度的过程，对于配置调度来说，第一网络设备120直接一次性地为终端设备110配置上行资源，终端设备110周期性的使用被配置的上行资源，当上行资源出现的周期与上行业务达到的周期不匹配时，容易产生时延抖动。对于动态调度来说，每次终端设备110有业务到达时，都需请求第一终端设备120为其配置上行资源，容易造成时延。
本申请实施例提供的调度方法，可以减少时延对上行业务传输带来的影响。
下面结合图2中的步骤S210-S230描述本申请实施例提供的调度方法。
在步骤S210中，终端设备向网络设备发送第一信息，其中第一信息包括与上行业务的模式信息。
上述上行业务可以具有一定的周期性，此时终端设备向网络设备上报的模式信息可以是与上行业务周期相关的信息；上行业务还可以不具备周期性，但是多个上行业务可以组成一个传输模式，或者说多个上行业务之间的时间间隔是固定的。从整个时域上看，上行业务可以具有多个传输模式，每个传输模式可以在时域上重复出现，且出现的时刻可以是具有规律的也可以是不具规律的。此时终端设备向网络设备上报的模式信息可以是与传输模式相关的信息。或者上行业务不符合上述情况，但是终端设备可以预估将要进行的多个上行业务的到达时刻，则终端设备向网络设备上报的信息还可以包括该多个上行业务到达时刻的信息。模式信息也可以理解为业务在时域上出现时刻的排列所形成的形状等等。
应理解，上述模式信息中不仅可以包含上行业务的模式信息还可以包括上行业务数据包的大小。
还应理解，上述多个上行业务可以是相同类型的上行业务还以不同类型的上行业务，本申请实施例对此不做具体限定。
为了便于理解，下面结合图3-图5详细说明上行业务的特点。图3与图4示出了上行业务具有周期性的特点。
当上行业务具有周期性时，每个周期内可以到达一个上行业务，例如图3中的周期310中有一个业务到达，从时域上来看，在后续的过程中每隔固定的时间周期310会重复出现。对于此种业务类型，终端设备可以上报上行业务的周期与起始时刻或者是多个上行业务中任一上行业务的到达时刻，以便网络设备根据上述信息，获取上行业务的传输形态。
当然也可以每个周期内到达多个上行业务，如图4，在周期310内出现多个业务，且从时域上来看，在后续的过程中每隔固定的时间，周期310会重复出现。此时除了上报第一周期即周期310的长度与上行业务的起始时刻之外，还可以上报时间偏移信息，时间偏移信息为周期310中的多个上行业务之间的时间间隔，参见图4中的时间间隔311，时间间隔312，与时间间隔313。
应理解上述时间偏移信息可以是上行业务之间的时间间隔，还可以是上行业务与周期边界之间的时间间隔，本申请实施例对此不做具体限定。
另外，时间偏移信息的形式可以是多样的，可以是显示的形式，例如可以是几个数值，该几个数值可以代表偏移信息；也可以是隐式的形式，例如使用位图信息来表示，位图信息中包含多个比特位，每个比特位可以对应一个时间单元，每个比特位上的值以为0或者为1，值为1或者为0的比特位可以用来表示一个时间单元上有上行业务。整个比特信息的时间单元的长度可以为第一周期的长度，结合图3与图4可知第一周期长度可以为周期310的长度。值为1或者为0的比特位与周期边界之间的时间间隔可以作为时间偏移信息。
上文描述的均为上行业务具有周期的情况，本申请实施例还可以包括上行业务不具有周期性的情况，即上行业务不具有周期性，但多个上行业务组成一个传输模式，在该传输模式下，该多个上行业务之间的时间间隔是固定的。上行业务可以划分为多个传输模式，每个传输模式在时域上可以规律性或者随机出现。正如图5中示出的上行业务的情况，如 图5所示，在时间间隔510上出现的多个上行业务的传输模式，在后续的某个时刻可以重新出现，例如在时间间隔530中出现与时间间隔510相同传输模式的上行业务。此种情况下，终端设备为每个传输模式分配索引信息，此时的第一信息中可以包含索引信息，索引信息中不仅可以包含某个传输模式下业务的到达时刻，还可以包含业务的大小，本申请实施例对此不做具体限定。
具体地，针对图5中示出的传输模式，可以预先定义好至少一种传输模式与索引信息之间的对应关系，或者网络设备也可以通过RRC信令配置好至少一种业务模式与索引信息的对应关系，以便终端设备向网络设备上报对应的索引信息给网络设备，网络设备根据上报的索引信息查找对应的业务模式，根据业务模式为终端设备配置上行资源，或者调整已经配置好的上行资源等等。
可选地，第一信息中还可以包括第一差值信息，第一差值信息用于指示上行业务到达时刻与上行资源出现时刻之间的差值。第一差值的出现表示了上行资源与上行业务之间出现了不匹配的情况，通过向网络设备上报第一差值信息可以使得网络设备进行上行资源的调整。
终端设备向网络设备上报第一信息的触发条件可以有多种，例如可以是当终端设备检测到上行资源与上行业务的到达时刻或者资源大小不匹配时，可以将第一信息上报给网络设备。或者也可以是终端设备定时上报，即终端设备处的定时器超时后，该定时器指示终端设备向网络设备上报第一信息，本申请实施例对此不做具体限定。
可选地，第一信息中除了包含上行业务的模式信息，还可以包含上行业务数据包的大小，以便网络设备根据上行业务数据包的大小分配上行资源。还可以包括第二差值信息，所述第二差值信息用于指示上行业务数据包的大小与上行资源大小之间的差值，网络设备可以根据第二差值信息调整上行资源的大小。
可选地，第一信息中还可以包含终端设备的相关信息；应理解，上述终端设备的位置相关信息可以包括终端设备的服务区域位置，终端设备的服务区域大小，还可以包括终端设备选择的服务波束信息等等。
应理解，上述终端设备的位置相关信息可以包括终端设备的服务区域位置，终端设备的服务区域大小，还可以包括终端设备选择的服务波束信息等等。其中服务波束可以利用参考信号的标识信息标识，还可以是利用服务波束自带的标识信息标识，本申请实施例对此不做具体限定。第一信息中还可以包括第一指示信息，所述第一指示信息用于指示当前波束是否能够覆盖所述终端设备的活动区域。发送终端设备相关信息能够帮助网络设备根据终端设备的相关信息，更好地完成调度。
在步骤S220中，网络设备向终端设备发送第二消息，所述第二消息用于指示上行业务被配置的上行资源。
网络设备在接收到第一信息之后，可以参考第一信息为上行业务配置上行资源。在不产生资源冲突的情况下，网络设备为上行业务配置与其业务模式相匹配的上行资源。
例如，网络设备接收到的第一信息中包含第一周期信息与上行业务的起始时刻时，可以将第一周期作为上行资源出现时刻的周期，将上行业务的起始时刻作为上行资源的起始时刻，以完成上行资源出现时刻与上行业务到达时刻的同步。若第一信息中还携带有上行业务数据包的大小，网络设备还可以同时为终端设备配置大小合适的上行资源，以完成上 行业务的传输，则此时第二信息中可以包含上行业务的起始时刻，第一周期信息。
或者还可以是网络设备接收到的第一信息中包含第一周期信息，上行业务的起始时刻时，时间偏移信息，网络设备可以将第一周期作为上行资源出现时刻的周期，将上行业务的起始时刻作为上行资源的起始时刻，以完成上行资源出现时刻与上行业务到达时刻的同步。若第一信息中还携带有上行业务数据包的大小，网络设备还可以同时为终端设备配置大小合适的上行资源，以完成上行业务的传输，则此时第二信息中可以包含上行业务的起始时刻，第一周期，以及时间偏移信息。
或者还可以是网络设备接收到的第一信息中包含索引信息，网络设备查找索引信息对应的传输模式，该传输模式可以指示多个上行业务的到达时刻以及多个上行业务数据包的大小，网络设备为上行业务配置与其传输模式相对应的上行资源，第二信息中可以包含上述索引信息，或者多个上行业务的到达时刻，或者多个上行业务数据包的大小。
或者还可以是网络设备接收到的第一信息中包含第一差值信息，网络设备根据第一差值调整已经配置好的上行资源，并在第二信息中携带第一差值信息。
应理解，第一差值信息用于调整已经配置好的上行资源相对原来出现时域位置的偏差和/或偏差的方向。
或者还可以是网络设备接收到的第一信息中包含第二差值信息，网络设备根据第二差值调整已经配置好的上行资源，并在第二信息中携带第二差值信息。
网络设备可以根据终端设备上报的上行业务数据包的大小与上行资源大小之间的差值调整被配置的上行资源，使得上行资源大小与上行业务数据包的大小的匹配。
应理解，所述终端设备可以通过RRC信令，或MAC CE上报第一信息，其中MAC CE可以是BSR，也可以是单独设计的专用MAC CE。终端设备还可以通过其他的控制PDU上报第一信息，本申请实施例对此不做具体限定。
应理解，网络设备可以通过RRC信令，或媒体介入控制层控制元素MAC CE，下行DCI向终端设备传输第二消息。第二信息可以复用上述已有的信令，还可以是新建信令本申请实施例对此不做具体限定。
复用已有的信令传输第一信息或者第二信息能够节省信令开销。
在步骤S230中，终端设备利用配置好的上行资源传输上行业务。

当需要发送数据时，处理器对待发送的数据进行基带处理后，输出基带信号至射频电路，射频电路将基带信号进行射频处理后将射频信号通过天线以电磁波的形式向外发送。当有数据发送到终端设备时，射频电路通过天线接收到射频信号，将射频信号转换为基带信号，并将基带信号输出至处理器，处理器将基带信号转换为数据并对该数据进行处理。为便于说明，图10中仅示出了一个存储器和处理器。在实际的终端设备产品中，可以存在一个或多个处理器和一个或多个存储器。存储器也可以称为存储介质或者存储设备等。存储器可以是独立于处理器设置，也可以是与处理器集成在一起，本申请实施例对此不做限制。
