Description

一种资源调度方法及装置
本申请要求在2017年8月11日提交国家专利局、申请号为201710686722.0、发明名称为“一种资源调度方法及装置”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
本申请涉及通信技术领域，尤其涉及一种资源调度方法及装置。
背景技术
在未来的5G通信系统，即新无线(New Radio，NR)系统标准化工作中，NR系统支持从扩频(sub)6GHz到60GHz频段，而在sub3GHz频段主要以长期演进(Long Term Evolution，LTE)系统部署为主。为了充分利用LTE频分双工(frequency division duplex，FDD)载波上行资源，NR系统上行传输可以和LTE系统上行传输共享LTE FDD载波的上行资源，既充分利用了LTE FDD载波上行频谱资源，同时也可以提高NR系统上行覆盖。目前，在LTE-NR双连接(Dual Connection，DC)场景下，LTE系统和NR系统仅共享LTE FDD载波的上行资源，共享的LTE FDD载波的上行资源可以看做是NR系统的一个增补上行(Supplementary Uplink，SUL)频率资源，对于增补上行资源来说，NR终端可以在NR FDD/时分双工(time division duplex，TDD)上行资源和增补上行资源中选择合适的随机接入信道接入到NR系统中来。
目前，在LTE-NR DC场景下，主基站(Master gNB，MgNB)(或者(Master eNB，MeNB)，以下均简称为主基站或MgNB)和辅基站(Secondary gNB，SgNB)(或者(Secondary eNB，SeNB)，以下均简称为辅基站或SgNB)均可以为终端提供数据传输服务。终端接入辅基站之前，辅基站会根据上下行资源的负载情况为终端盲配置1.8GHz的SUL或3.5GHz的上行(Uplink，UL)频率资源，终端在辅基站盲配置的上行资源中随机接入辅基站。
然而，由于辅基站是为终端盲配置上行资源，导致终端通过盲配置的上行资源接入辅基站的成功率很低，降低了系统效率。

具体实施方式
下面将结合附图对本申请作进一步地详细描述。
本申请实施例可以应用于各种移动通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、演进的长期演进(evolved Long Term Evolution，eLTE)系统、5G系统(例如NR系统)等其它移动通信系统。
以下，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
1)、终端，又称之为用户设备(User Equipment，UE)，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。常见的终端例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等。
2)、接入网设备，可以是普通的基站(如NodeB或eNB)，可以是新无线控制器(New Radio controller，NR controller)，可以是NR系统中的gNB，可以是集中式网元(Centralized Unit)，可以是新无线基站，可以是射频拉远模块，可以是微基站，可以是中继(relay)，可以是分布式网元(Distributed Unit)，可以是接收点(Transmission Reception Point，TRP)或传输点(Transmission Point，TP)或者任何其它无线接入设备，但本申请实施例不限于此。
本申请实施例适用于LTE系统与NR系统双连接的场景，或NR系统与NR系统的双 连接场景。如图1所示，为适用于本申请实施例的一种双连接场景示意图。图1中，接入网设备101可以同时工作在LTE系统与NR系统，即接入网设备101可以同时建立LTE小区104连接和NR小区105连接。LTE小区104中的终端102为支持LTE系统的终端，NR小区105中的终端103为支持NR系统的终端。终端102采用低频频谱f1与接入网设备101进行上行通信、采用低频频谱f2与接入网设备101进行下行通信。终端103采用低频频谱f1与接入网设备101进行上行通信、采用高频频谱f3与接入网设备101进行下行通信。
在双连接的场景中，每个终端只有一个无线资源控制(Radio Resource Control，RRC)状态，即RRC连接(RRC_connected)状态或者RRC空闲(RRC_idle)状态。基于上述原则，第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)提出了两种双连接场景下的控制平面结构。如图2所示，为第一种双连接场景下的控制平面结构示意图。图2所示的结构可以称为，C1结构。
第一种双连接场景下的控制平面结构：主基站和辅基站进行无线资源管理(Radio Resource Management，RRM)协调后，共同负责将最终的RRC信令发送给终端。终端的RRC实体识别来自主基站的RRC信令后只将响应信息反馈给主基站的RRC实体。
如图3所示，为第二种双连接场景下的控制平面结构示意图。图3所示的结构可以称为，C2结构。
第二种双连接场景下的控制平面结构：主基站和辅基站进行RRM协调后，共同负责将最终的RRC信令发送给终端。终端的RRC实体识别来自主基站和辅基站的RRC信令后分别给两个基站的RRC实体发送响应消息。
例如，LTE-NR DC场景时，LTE基站可以作为主基站，NR基站可以作为辅基站。主基站下某个小区的工作频点可以为band1中某个20M的载波，例如下行频点为2120MHz，上行频点为1930MHz；辅基站下有一个待添加为主辅小区(Primary Secondary Cell，PSCell)的NR小区，主辅小区包括一个3.5GHz的TDD载波，以及一个1.8GHz的增补上行资源(用于提升3.5G的TDD载波的上行覆盖)；主基站和辅基站之间通过X2或Xn口进行交互。在该场景下，终端可以为支持LTE频段和NR频段的双模终端，终端可以通过主基站和辅基站进行业务传输，从而提高终端的传输效率。
本申请实施例中，下行载波可以理解为载波中(包括非载波聚合(Carrier Aggregation，CA)场景下的载波和CA场景下的成员载波(Component Carrier，CC))用于下行传输的部分或服务小区中(包括CA场景下的服务小区和非CA场景下的服务小区)用于下行传输的部分；上行载波可以理解为载波中(包括非CA场景下的载波和CA场景下的CC)用于上行传输的部分或服务小区中(包括CA场景下的服务小区和非CA场景下的服务小区)用于上行传输的部分。其中CA场景下的CC可以为主CC或辅CC，CA场景下的服务小区可以为主小区或辅小区。该上行载波也可以称为上行资源，下行载波也可以称为下行资源。相应的，载波或服务小区用于下行传输的部分可以理解为下行资源或下行载波。例如，在频分双工(frequency division duplex，FDD)系统中，载波上用于上行传输的频率资源可以理解为该上行资源或上行载波；用于下行传输的频率资源可以理解为下行资源或下行载波。在再如，在时分双工(time division duplex，TDD)系统中，载波上用于上行传输的时域资源可以理解为该上行资源或上行载波；用于下行传输的时域资源可以理解为下行资源或下行载波。
结合上述描述，参见图4，为本申请实施例提供的一种通信方法流程示意图。该方法 中，第一接入网设备与第二接入网设备通过双连接方式为终端服务，第一接入网设备可以为辅接入网设备，第二接入网设备为主接入网设备。例如，LTE-NR DC场景下，第一接入网设备可以为NR基站，第二接入网设备可以为LTE基站。当然，以上只是示例，第一接入网设备与第二接入网设备的类型可以根据实际情况确定，第一接入网设备也可以为主接入网设备，第二接入网设备也可以为辅接入网设备，在此不再逐一举例说明。
参见图4，该方法包括：
步骤401：第二接入网设备向第一接入网设备发送添加请求消息；所述添加请求消息中包括第一信号测量值；所述第一信号测量值为第一上行载波对应的下行载波的信号测量值。
所述添加请求消息中还包括以下一项或多项：
小区的物理小区标识；即第一上行载波对应下行载波的物理小区标识。
小区中包括的载波的频点信息；即第一上行载波对应下行载波的的频点。
小区中包括的载波的带宽信息，即第第一上行载波对应下行载波的的带宽。
需要说明的是，本申请实施例中，上行载波和下行载波如果存在对应关系，在FDD传输模式下，表示上行载波和下行载波属于一个频带(band)，一个band定义了一段下行载波所在频域范围，和一段上行载波所在的频域范围；在TDD传输模式下，表示上行载波和下行载波的频点相同。例如，第一上行载波的频点为3.5GHz，第一上行载波对应下行载波的频点为3.5GHz，或者第一上行载波对应下行载波与第一上行载波属于一个band。
当然以上只是示例，上行载波和下行载波的对应关系还可以存在其他形式，在此不再赘述。
步骤402：第一接入网设备从第二接入网设备接收添加请求消息。
步骤403：所述第一接入网设备根据所述第一信号测量值确定终端向所述第一接入网设备发送前导码所使用的第三上行载波，并向所述第二接入网设备发送添加请求确认消息。
所述添加请求确认消息中包括载波指示信息，所述载波指示信息用于指示所述第三上行载波，所述第三上行载波为所述第一上行载波和第二上行载波中的至少一种，所述第二上行载波与所述第一上行载波属于所述第一接入网设备的同一小区。
本申请实施例中，第二上行载波可以为增补上行(supplementary uplink，SUL)资源，例如SUL载波或频率(frequency)，其中SUL资源是指仅有上行资源用于当前通信制式的传输。例如，对于一个载波，仅有上行资源用于传输。例如，在第五代(5G)移动通信系统，又称为新无线通信系统中，载波A仅用于NR的上行传输，该载波不用于下行传输或者用于LTE通信系统的下行传输而不用于NR的下行传输，则该载波A为SUL资源。
步骤404：第二接入网设备从所述第一接入网设备接收添加请求确认消息。
所述添加请求确认消息中包括载波指示信息；所述载波指示信息用于指示终端向所述第一接入网设备发送前导码所使用的第三上行载波，所述第三上行载波为所述第一接入网设备根据所述第一信号测量值确定的。
步骤405：第二接入网设备向所述终端发送所述载波指示信息。
通过上述方法，第一接入网设备根据第一上行载波对应的下行载波的第一信号测量值，确定终端发送前导码所使用的第三上行载波，因此终端发送前导码所使用的第三上行载波的信号质量能够得到保证，第一接入网设备更容易接收到终端发送的前导码，从而提高终端接入第一接入网设备的接入效率。
第二接入网设备可以通过RRC连接重配置信令向终端发送所述载波指示信息。RRC连接重配置信令中还可以包括第一接入网设备发送给所述终端的其他配置信息，例如第一上行载波的配置信息、第二上行载波的配置信息、随机接入的前导码配置信息等，上述信息都是第一接入网设备发送给第二接入网设备之后，第二接入网设备可以解析添加请求确认消息中所包括的载波指示信、第一上行载波的配置信息、第二上行载波的配置信息、随机接入的前导码配置信息等息，也可以不解析上述信息，直接将上述信息通过RRC连接重配置信令透传给终端。
步骤406：终端接收第二接入网设备发送的载波指示信息。
步骤407：终端向通过所述第三上行载波向所述第一接入网设备发送前导码。
步骤401之前，终端与第二接入网设备建立了RRC连接，同时终端与第二接入网设备交互了第一接入网设备所包括的每个载波的参考信号接收功率(Reference Signal Receiving Power，RSRP)或下行路损值。
例如，在双连接场景下，第一接入网设备可以为NR基站，第二接入网设备可以为LTE基站。第二接入网设备可以通过RRC重配(reconfiguration)信令将第一接入网设备中，待测量对象(可以为载波、小区、参考信号等)的相关信息发送给终端，其中，所述相关信息包括但不限于绝对无线频道编号(Absolute Radio Frequency Channel Number，ARFCN)、允许测量带宽(allowed Meas Bandwidth)、天线对口配置(presenceAntennaPort)等信息；终端通过媒体接入控制(Media Access Control，MAC)层的上行专用控制信道将上述待测量对象的测量结果上报给第二接入网设备。
具体交互过程可以如下：
步骤一：第二接入网设备通过RRC重配置信令通知终端待测量的小区的频点信息、带宽信息、小区标识等信息。
其中，待测量的小区中可以包括第一上行载波、与第一上行载波对应的下行载波、第二上行载波。例如，第一上行载波为NR 3.5G UL载波、与第一上行载波对应的下行载波为NR 3.5G下行(downlink，DL)载波、第二上行载波为NR 1.8G SUL载波。
可选的，第二接入网设备通过RRC重配置信令通知终端待测量的小区中每个载波中承载的参考信号的发射功率，参考信号可以是指同步信号块(Synchronization Signal block，SS block)、信道状态信息参考信号(CSI reference signals，CSI-RS)、小区参考信号(Cell Reference Signal，CRS)等信号。
可选的，待测量的载波为1.8G SUL时，第二接入网设备通过RRC重配置信令通知终端所述1.8G SUL对应的LTE 1.8G下行(downlink，DL)载波的小区标识信息、频点信息、参考信号的发送功率等信息。
步骤二：终端根据第二设备发送的RRC重配置信令(RRC重配置信令中的measConfig信元将所需测量的载波信息通知给终端)，对待测量的载波进行测量，获得测量结果，并通过RRC消息(例如measurement Report消息)将测量结果上报给第二接入网设备。
终端上报的结果至少包括每个小区中每个载波的信号测量值。
信号测量值可以为小区中上行载波对应的下行载波的参考信号接收功率值；或者，所述信号测量值可以为小区中上行载波对应的下行载波的下行路损值。
例如，小区中包括的载波分别为：第一上行载波为NR 3.5G UL载波、与第一上行载波对应的下行载波为NR 3.5G DL载波、第二上行载波为NR 1.8G SUL载波。此时，终端 的测量结果包括第一信号测量值：NR 3.5G DL载波的信号测量值、第二信号测量值：NR1.8G SUL载波对应的下行载波的信号测量值等。
需要说明的是，参考信号接收功率值与下行路损值的具体计算方法，本申请实施例对此并不限定，在此不再赘述。
步骤401中，所述添加请求消息中还包括第二信号测量值，所述第二信号测量值为所述第二上行载波对应的下行载波的信号测量值。所述第二上行载波可以为所述第一上行载波的增补上行资源。

步骤403中，第一接入网设备可以通过多种方法确定终端向所述第一接入网设备发送前导码所使用的第三上行载波，下面详细描述。
一种可能的实现方式中，第一接入网设备根据第一信号测量值确定所述第一上行载波的信号测量值，其中，确定出的所述第一上行载波的信号测量值等于所述第一信号测量值；
所述第一接入网设备若确定所述第一信号测量值大于第一预设阈值，且所述第一上行载波的负载大于第二预设阈值，则所述第一接入网设备将第二上行载波确定为第三上行载波；
所述第一接入网设备若确定所述第一信号测量值小于或等于第一预设阈值，且所述第一上行载波的负载小于或等于第二预设阈值，则所述第一接入网设备将第一上行载波确定为第三上行载波。
需要说明的是，第一上行载波与第一上行载波对应的下行载波具有对应关系，根据信道的互易性，第一上行载波对应的下行载波的信号测量值，可以与第一上行载波的信号测量值相等，因此第一网络设备可以根据第一信号测量值确定第一上行载波的信号测量值。相应的，第一网络设备可以根据第二上行载波对应的下行载波的信号测量值确定第二上行载波的信号测量值。
一种可能的实现方式中，所述第一接入网设备根据所述第一信号测量值确定所述第一上行载波的信号测量值，并根据所述第二信号测量值确定所述第二上行载波的信号测量值；其中，确定出的所述第一上行载波的信号测量值等于所述第一信号测量值，确定出的所述第二上行载波的信号测量值等于所述第二信号测量值。
所述第一接入网设备若确定所述第一信号测量值小于或等于第一预设阈值，且所述第一上行载波的负载小于或等于第二预设阈值，同时，所述第一接入网设备若确定所述第二信号测量值小于或等于第一预设阈值，且所述第为上行载波的负载小于或等于第二预设阈 值，则所述第一接入网设备将第一上行载波以及第二上行载波均确定为第三上行载波。此时，终端可以使用第一上行载波以及第二上行载波中的任意一个载波发送前导码，或者在第一上行载波以及第二上行载波中均发送前导码。
一种可能的实现方式中，所述第一接入网设备根据所述第一信号测量值确定所述第一上行载波的信号测量值，并根据所述第二信号测量值确定所述第二上行载波的信号测量值；其中，确定出的所述第一上行载波的信号测量值等于所述第一信号测量值，确定出的所述第二上行载波的信号测量值等于所述第二信号测量值。
所述第一接入网设备若根据所述第一上行载波的信号测量值以及所述第二上行载波的信号测量值，确定第一上行载波的信号质量优于所述第二上行载波的信号质量，则将所述第一上行载波确定为所述终端向所述第一接入网设备发送前导码所使用的第三上行载波；或者，所述第一接入网设备若根据所述第一上行载波的信号测量值以及所述第二上行载波的信号测量值，确定所述第二上行载波的信号质量优于所述第一上行载波的信号质量，则将所述第二上行载波确定为所述终端向所述第一接入网设备发送前导码所使用的第三上行载波。
当然，以上只是示例，第一接入网设备可以通过其他方法确定终端向所述第一接入网设备发送前导码所使用的第三上行载波，在此不再赘述。
步骤403中，第一接入网设备确定出的载波指示信息可以通过至少1个比特位指示第三上行载波。例如，添加请求确认消息中包括第一上行载波的配置信息以及第二上行载波的配置信息时，可以将上述信息配置的先后顺序用0和1表示，比如，添加请求确认消息中先配置了第二上行载波的配置信息，再配置了第一上行载波的配置信息，那么载波指示信息所包括的比特位的取值为0时，表示第三上行载波为第一上行载波，载波指示信息所包括的比特位的取值为1时，表示第三上行载波为第二上行载波，当然以上只是示例，载波指示信息的具体形式并不不做限定。
可选的，载波指示信息的指示也可以通过上行载波激活字段来指示，添加请求确认消息中可以有2bit的上行载波激活字段，第一个bit表示一个上行载波的激活信息，0表示不激活，1表示激活，第一个bit可以按照先后顺序，也可以按照其他的规则来表示一个上行载波的激活状态，具体不做限定，例如，第一个bit表示第一上行载波，即1.8G增补上行载波，第二个bit表示第二上行载波，即3.5G专用(dedicated)上行载波，那么载波指示信息为10时，表示终端在1.8G增补上行载波上发送专享的前导码，载波指示信息为01时，表示UE在3.5G dedicated上行载波上发送专享的前导码，载波指示信息为11时，表示两个上行载波终端都激活，终端可以在两个上行载波上发送专享的前导码。
