背景技术
长期演进(Long Term Evolution，LTE)系统中，网络架构分为集中式和分布式两种架构，其中，对于分布式架构，基站包括基带功能和射频功能；而集中式架构是将基带功能放在基带控制单元(baseband control unit，BBU)中,把射频功能放在射频拉远单元(remote radio unit，RRU)中，其中，BBU和RRU之间需要采用光纤或微波等大容量传输介质进行连接。以上两种架构是与终端设备无关的。也就是说一旦确定架构，对于一个小区里的所有的终端设备，要么都是分布式调度，要么都是集中式调度。
分布式架构下的调度是各个基站自己调度，跨基站的小区间协调效果不好，从而使跨基站小区间的干扰比较大，进而导致位于小区边缘终端设备的吞吐量下降，但是，分布式架构的好处是节省传输网络的带宽，因为BBU和RRU合一，就不需要额外的传输网络(前传Fronthual)。集中式架构好处是系统性能好，因为可以集中调度多个小区的无线资源(比如借助于CoMP技术)，从而可以协调多个小区间的无线资源，降低干扰，提升小区边缘用户的吞吐量，但是BBU和RRU分离，BBU和RRU之间因为传输的是物理(PHY)层处理后的数据，BBU和RRU之间的传输网络(通常称为前传Fronthaul)需要传输大量数据，带宽需求非常大。进一步的，如果小区支持的频率带宽增大时，空口需要传输更多的数据，对应的传输网络带宽需求也随着进一步增大，从而对传输网络的带宽造成很大压力。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行 清楚、完整地描述，显然，所描述的实施例是本发明的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
虽然在前述背景技术部分以LTE系统为例进行了介绍，但本领域技术人员应当知晓，本发明不仅仅适用于LTE系统，也可以适用于其他无线通信系统，例如全球移动通信系统(Global System for Mobile Communication，GSM)，移动通信系统(Universal Mobile Telecommunications Systemc，UMTS)，码分多址接入(Code Division Multiple Access，CDMA)系统，以及新的网络系统等。下面以LTE系统为例进行具体实施例的介绍。
本发明实施例涉及的终端设备，可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(PCS，Personal Communication Service)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(WLL，Wireless Local Loop)站、个人数字助理(PDA，Personal Digital Assistant)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用户装备(User Equipment)。
本发明实施例所涉及第一节点或第二节点，可以是基站，该基站可用于将收到的空中帧与IP分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)网络。该基站 还可协调对空中接口的属性管理。例如，基站可以是GSM或CDMA中的基站(BTS，Base Transceiver Station)，也可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(eNB或e-NodeB，evolutional Node B)，本申请并不限定。
本发明实施例所涉及第二节点也可以为基站控制器。
为了更好的说明本发明的技术方案，现在对现有技术中的分布式协议栈架构和集中式协议栈架构进行分别说明：
如图1所示，分布式协议栈架构就是将基带功能、射频功能全部放在基站，由基站和终端设备之间按照图1所示的协议栈进行通信。
如图2所示，集中式协议栈架构就是将基站的功能放在一个基带近控制单元(baseband control unit，BBU)中，将射频功能(RF)放在射频拉远单元(remote radio unit，RRU)中，BBU和RRU之间采用光纤进行连接，形成BBU-RRU-UE的通信链路。
对于现有技术而言，LTE系统中，协议栈每处理一次，就会带来额外的开销。比如下行数据，基站从SGW收到数据后，要经过分组数据汇聚层协议(Packet Data Covergence Protocol，PDCP)层、无线链路控制(Radio Link Control，RLC)层、媒体接入控制(Media Access Contronl，MAC)层和PHY层处理后，然后通过射频模块发送出去。LTE系统的集中式调度架构中的BBU和RRU之间，传输的是PHY层处理后的数据，因为SGW和基站之间传输的是未经PDCP层、RLC层、MAC层和PHY层处理的互联网协议(Internet Protolcol，IP)层数据包，所以传输网络的带宽需求很高。而分布式调度架构中BBU和RRU合成一个设备，基站从SGW收到数据后，在基站内部经过PDCP层、RLC层、MAC层和PHY层处理，然后由射频模块发送出去，所需要的传输网络带宽相对就比较小。
本发明实施例所提供的方法，引入了针对每个终端设备的基本信息和/或网络信息确定调度节点，换句话说，针对每个终端设备采用灵活的协议栈架 构代替传统的固定协议栈架构，即动态确定该终端设备的调度节点，即该终端设备被集中式调度还是还是分布式调度。
另一个方面，当一个小区存在多个终端设备时，可以针对多个终端设备中的每个终端设备的基本信息和/或网络信息确定调度节点，即可以实现一个小区中的不同的终端设备采用不同的调度方式(集中式调度或分布式调度)。更确切的说，小区里部分终端设备采用分布式调度，使传输网络带宽的需求降低；小区里部分终端设备采用集中式调度，使小区的系统性能得到提升。也就是说本发明实施例所提供的方案，可以针对每个终端设备灵活确定调度节点，在系统性能和传输网络带宽需求之间实现平衡，在得到集中式调度的增益的情况下，同时降低了针对于每个终端设备固定调度节点的传输网络带宽需求。
具体的，通过下述不同的实施例对本发明实施例的技术方案进行说明。
图3这本发明一种数据传输方法提供的一个实施例的流程示意图，该方法涉及至少一个第一节点和至少一个第二节点，其中该第一节点与该第二节点都具用调度功能，该方法包括：
301、该第二节点根据终端设备的基本信息和/或网络信息确定第一指示信息，该第一指示信息用于指示该终端设备由该第一节点调度或由该第二节点调度。
302、该第二节点向该第一节点发送第一指示信息。
303、如果该第一指示信息指示该终端设备由该第一节点进行调度，则该第二节点向该第一节点发送未经过该第二节点的调度功能处理的数据包；或者，如果该第一指示信息指示该终端设备由该第二节点进行调度，则该第二节点向该第一节点发送经过该第二节点的调度功能处理后的数据包。
304、在第一节点接收经过调度功能处理后的数据包，或者接收未经调度功能处理后的数据包，具体的可以做如下操作：
如图3a所示,如果该终端设备由该第一节点进行调度，该第一节点接收 未经过该第二节点的调度功能处理的数据包，所述第一节点对所述未经过所述第二节点的调度功能处理的数据包进行处理后，发送给终端设备；或者,如图3b所示，如果该终端设备由该第二节点进行调度，则该第一节点接收经过该第二节点的调度功能处理后的数据包，所述第一节点对经过所述第二节点的调度功能处理后的数据包进行处理后，发送给终端设备。
相较与现有技术，本发明提供的方案根据终端设备的基本信息和/或网络信息确定指示信息，该指示信息用于指示该终端设备的调度节点，从而针对每个终端设备灵活确定调度节点，在保持调度增益的情况下，避免固定协议栈架构下，当小区的传输网络带宽增加时，对传输网络的带宽造成的压力，同时降低了针对于每个终端设备固定调度节点的传输网络带宽需求。
在一个示例中，当终端设备的基本信息和/或网络信息发生变化后，该第二节点与该第一节点之间协商改变调度节点，根据终端设备变化后的基本信息和/或网络信息确定第二指示信息，向该第一节点发送第二指示信息，该第二指示信息用于指示该终端设备由该第一节点调度或该第二节点调度。
在另一个示例中，该第一指示信息可以包括：调度指示或承载类型指示。
其中，上述提到的第一指示信息还包括终端设备的承载标识，该承载标识用于指示该终端设备的承载标识所对应承载上的数据由该第一节点进行调度或者由该第二节点进行调度。
在另一个示例中，该第二节点向该第一节点发送未经过该第二节点的调度功能处理的数据包，包括：该第二节点向该第一节点发送PDCP PDU或者IP PDU。
在另一个示例中，该第二节点向该第一节点发送经过该第二节点的调度功能处理后的数据包，包括：该第二节点向该第一节点发送MAC PDU或者PHY层数据。
其中，该MAC PDU包括：由MAC层调度功能处理后的MAC PDU；或者由MAC层调度功能或混合自动重传请求(hybrid automatic repeat request， HARQ)功能处理后的MAC PDU。为了描述方便，在本申请中统称为MAC PDU。
在另一个示例中，该终端设备基本信息包括并不限于：终端设备的地理位置、业务Qos信息、测量报告、终端的能力或终端设备的优先级信息。当然，这些举例仅是为了说明本发明实施例，只要该终端设备的基本信息能作为确定第一指示信息或第二指示信息的依据，都属于本发明所要保护的范围，在此不再赘述。
该终端设备的网络信息包括并不限于传输网络的负载信息，例如Fronthual的传输网络的负载信息。这些举例仅是为了说明本发明实施例，只要该终端设备的网络信息能作为确定第一指示信息或第二指示信息的依据，都属于本发明所要保护的范围，在此不再赘述。
进一步，确定第一指示信息或确定第二指示信息，皆可以根据表2中的对应关系确定：
Figure PCTCN2015100126-appb-000001
表2
进一步，该网络信息包括并不限于传输网络负载信息，具体的，在确定或者变更终端设备的调度节点时，可以根据网络信息(比如Fronthaul传输网络负载)确定。例如，当传输网络的负载重，那么为了降低fronthaul的带宽，可以把终端设备确定为分布式调度。具体的确定关系可以参考表3。
  由第二节点调度 由第一节点调度
网络信息 传输网络的负载轻 传输网络的负载重
表3
示例性的，所述网络信息可以包括传输网络的负载情况、硬件资源负载情况或者综合负载信息，即考虑了硬件和网络负载情况等信息。具体的确定步骤可以参照上述的表述，在此不再赘述。
具体实现时，可以对传输网络的负载情况设置一个门限，如果负载达到或者超过一个预先定义的门限，认为负载重；如果没达到一个预先定义的门限，认为负载轻。
需要特别强调的是，表2中的地理位置、测量报告或UE的能力与表3中的网络信息可以单独使用，也可以将表2中的地理位置、测量报告或UE的能力信息任一个和表3中的网络信息结合起来使用，结合时，每个确定标准作为一个确定条件，由实现方法最后综合进行确定。
作为一个示例，终端设备的基本信息和网络信息可以结合使用。假设有多个终端设备存在的场景，比如当传输网络的负载重时，那么只选择一部分小区边缘终端设备由第二节点调度(集中式调度)，另一部分位于小区边缘终端设备由第一节点调度(分布式调度)。或者，作为另一个示例，比如传输网络的负载轻，选择服务小区信号强度大于第一门限的部分终端设备由第二节点调度(集中式调度)，另一部分服务小区信号强度大于第一门限的终端设备由第一节点调度(分布式调度)。
下面结合附图在各具体实施例中对各种可能的实现方式进行详细介绍。
本发明描述的技术方案可以适用于LTE系统，或其他采用各种无线技术的无线通信系统。此外还适用于使用LTE系统后续的演进系统，如第五代5G系统等。为了清楚起见，这里仅以LTE系统为例进行说明，在LTE系统中，网络设备和终端设备之间进行数据传输。
本发明所说的调度功能可以为MAC层的调度功能，至少包括无线资源分配功能，进一步可选的，还包括下述至少一种功能或特性的处理：逻辑信息映射功能、复用功能、解复用功能、调度信息报告、优先级处理、逻辑信道优先级或传输格式选择功能。在本发明中，终端设备的数据由一个节点调度， 等同于该数据经过该节点调度功能处理、或者该数据由该节点进行无线资源分配，当然，这仅是为了说明本发明技术方案所举的例子，本发明包括并不限于上述举例。
本发明所提供的方案是针对每个终端设备基本信息和/或网络信息，灵活配置协议栈架构的方法。例如，根据每个终端设备的位置或者业务特性，确定对该终端设备进行集中式调度还是分布式调度。
比如，可以把地理位置位于小区边缘的终端设备由第二节点进行集中式调度，把地理位置位于非小区边缘的终端设备放在第一节点进行分布式调度，这样位于小区边缘的终端设备可以因为集中式调度降低小区间的干扰，性能得到保障，吞吐量得到提升；位于非小区边缘的终端设备的数据因为射频、PHY和/或MAC层功能放在第一节点，对传输网络的需求就大大降低了。通常系统评估的模型认为，小区边缘终端设备占小区总共终端设备的20％左右。按照这个假设，那么相对于现有技术的静态的集中式调度架构，因为80％的非边缘终端设备采用分布式调度，fronthaul带宽就可以大大降低；因为20％的边缘终端设备采用集中式调度，这些终端设备使用的无线资源就可以得到很好的协调，从而降低了小区间干扰，使得这些边缘终端设备的吞吐量得到保证。
为了更好的说明本发明实施例所涉及的方法，其中，当终端设备由第一节点调度时，是分布式调度，当终端设备由第二节点调度时，是集中式调度，这仅是为了更好的说明本发明实施例所举的例子，本发明包括并不限于此，当然本发明所涉及的方法，也可以适用于多个终端设备和/或多个节点的场景，在此不再赘述。
如图4所示，本实施例提供了另一种传输数据的方法，其中，当终端设备由第一节点调度时，是分布式调度，当终端设备由第二节点调度时，是集中式调度，该方法可以包括以下步骤：
401、第二节点和终端设备1之间建立RRC连接。
402、第二节点根据终端设备1的基本信息和/或网络信息确定调度指示。
需要特别说明的是，该基本信息可以包括终端设备的地理位置、业务Qos信息、测量报告、终端的能力或终端设备的优先级信息；该网络信息可以包括输网络负载，比如Fronthaul传输网络负载。这些仅是本发明所举的例子，本发明包括并不限于此。
例如，第二节点可以根据上述表2中终端设备的基本信息和/或上述表3中网络信息来确定调度指示。在此不再赘述。
403、第二节点向第一节点发送调度指示，该调度指示用于指示终端设备1由第一节点进行调度。

404、第二节点接收SGW发送的终端设备1的下行数据包。
405、第二节点将该下行数据包经过PDCP层处理，生成PDCP PDU后，将PDCP PDU发送给第一节点。
需要特别说明的是，第二节点将终端设备1的下行数据转换成PDCP PDU后发送，当终端设备1变更为由第二节点调度时，可以由第二节点的PDCP层继续为终端设备1提供服务，因为PDCP层具有SN序列号，通过状态报告就可以获知传输成功的数据包和未传输成功的数据包，进而对未传输成功的数据包继续传输，从而可以保证终端设备1业务连续性。
406、第一节点收到第二节点发送的PDCP PDU数据包后，对该数据包进行处理后，通过第一节点与终端设备1之间的无线链路发送给终端设备1。
具体的，第一节点接收PDCP PDU后，经过第一节点的RLC层、MAC层的调度功能处理和PHY层处理后，通过射频功能发送给终端设备1。
407、终端设备1接收第一节点发送的该第一节点处理后的数据包。
如图5所示，本实施例提供了另一种传输数据的方法，该实施例与图4 所示的实施例类似，不同之处在于：
405a、第二节点将终端设备1的下行数据包经过第二节点的IP层处理，生成IP PDU后，将IP PDU发送给第一节点。
406a、第一节点收到第二节点发送的IP PDU数据包后，第一节点对该IP PDU进行处理后，通过第一节点与终端设备1之间的无线链路发送给终端设备1。
具体的，第一节点接收IP PDU后，经过第一节点的PDCP层、RLC层、MAC层的调度功能处理后和PHY层处理后，通过射频功能发送给终端设备1。
407、终端设备1接收第一节点发送的该第一节点处理后的数据包。
如图6所示，为了更好的说明本发明实施例的技术方案，下面对本发明实施例进一步说明，当终端设备由第一节点调度时，是分布式调度，当终端设备由第二节点调度时，是集中式调度，该方法可以包括以下步骤：
408、终端设备2与第二节点之间建立RRC连接。

具体的，终端设备的基本信息和/或网络信息所包括的内容请参照上述实施例。
具体的，确定调度指示的方法请参照上述实施例，在此不再赘述。
410、第二节点向第一节点发送调度指示，该调度指示用于指示该终端设备2由第二节点进行调度。
可选的，411、第二节点与终端设备2之间建立无线承载，第二节点与SGW之间建立S1承载。
412、第二节点接收SGW发送的下行数据。
413、第二节点对该下行数据在第二节点的MAC层进行调度，生成MAC PDU。
具体的，该数据可以经过第二节点的PDCP层处理、RLC层处理和MAC层 调度处理后，生成MAC PDU。
414、第二节点向第一节点发送终端设备2的MAC PDU。
415、第一节点收到该终端设备2的MAC PDU后，将终端设备2的MAC PDU经过第一节点的PHY层处理后，经过射频功能处理，通过第一节点与终端设备2之间的无线链路发送给终端设备2。
416、终端设备2接收第一节点发送的第一节点处理后的数据。
如图7所示，本实施例提供了另一种传输数据的方法，该实施例与图6所示的实施例类似，不同之处在于：
413a、第二节点对终端设备2的下行数据在第二节点的PHY层进行调度，生成PHY层数据。
具体的，该数据可以经过第二节点的PDCP层处理、RLC层处理、MAC层处理和PHY层处理后，生成PHY层数据。
414a、第二节点向第一节点发送终端设备2的PHY层数据。
415a、第一节点收到该终端设备2的PHY层数据后，将终端设备2的PHY层数据通过第一节点与终端设备2之间的无线链路发送给终端设备2。
416a、终端设备2接收第一节点发送的数据。
相较与现有技术，图4至图7所示的实施例所提供的方案，通过根据终端设备的基本信息和/或网络信息，动态的决定被第一节点调度(分布式调度)或第二节点调度(集中式调度)，当确定由第一节点调度时，传输网络带宽的需求就会降低；或者当确定由第二节点调度时，小区的系统性能将得到提升。进一步，并且一个小区里的终端设备的调度方式可以随着终端设备或者网络信息(比如Fronthaul传输网络负载)发生变更。从而实现系统性能和传输网络带宽需求之间的平衡。
图9为本发明一种数据传输方法的另一个实施例，该实施例与图4所示 的实施例类似，不同之处在于：
402c，第二节点根据终端设备1的基本信息和/或网络信息确定承载类型指示。
需要特别说明的是，本发明中的承载类型可以是指第一节点和第二节点之间所承载(bearer)所传输(carry)数据的类型。比如当第一节点和第二节点之间的承载所传输的是IP PDU或PDCP PDU，我们这里称这种承载类型为IP PDU或者PDCP PDU；如果第一节点和第二节点之间的承载所传输的是MAC PDU或PHY数据，我们这里称这种承载类型为MAC PDU或PHY数据；
所以在本发明中实施例中，第一节点和第二节点之间的承载类型为PDCP PDU或MAC PDU，也就是指第一节点和第二节点之间的承载(bearer)所传输(carry)的数据的类型是PDCP PDU或MAC PDU；这仅是为了理解本发明所举的例子，本发明包括并不限于此，对于其他的承载类型，只要能够确定终端设备的调度节点都属于本发明所保护的范围，在此不再赘述。
具体的，根据终端设备1的基本信息和/或网络信息确定承载类型指示皆可以根据表4和表5所示的对应关系确定。也就是说，当承载类型为MAC PDU或PHY层数据时，该终端设备1由第二节点调度，当承载类型为PDCP PDU或者IP PDU时，该终端设备1由第一节点调度。从而第一节点可以根据承载类型获取调度信息。

表5
所述网络信息可以包括传输网络的负载情况、硬件资源负载情况或者综合负载信息，即考虑了硬件和网络负载情况等信息。
403c、第二节点向第一节点发送该承载类型指示，用于指示第二节点与第一节点之间传输的数据包类型为PDCP PDU或IP PDU。
需要特别说明的是，若是第二节点与第一节点之间传输的数据包为PDCP PDU或IP PDU，则第一节点可以获知终端设备1由第一节点进行调度。
图10为本发明一种数据传输方法的另一个实施例的流程示意图，该实施例与图6所示的实施例类似，不同之处在于：
409b、第二节点根据终端设备2的基本信息和/或网络信息确定承载类型指示。
具体的，第二节点根据终端设备2的基本信息和/或网络信息确定承载类型指示皆可以根据上述表4和表5所示的对应关系确定。
410b、第二节点向第一节点发送该承载类型指示，用于指示第二节点与第一节点之间传输的数据包类型为MAC PDU或PHY层数据。
图9或图10所示的实施例，还可以进一步细化为：终端设备1的基本信息进一步包括承载标识，该承载标识用于指示终端设备的承载标识所对应的承载上的数据由第一节点调度还是由第二节点调度；或者，该承载标识用于指示终端设备的承载标识所对应承载上的数据的数据类型为MAC PDU或PHY数据，或者PDCP PDU或者IP PDU。
需要特别说明的是，若是第二节点与第一节点之间传输的数据包为MAC PDU或PHY层数据，则第一节点可以获知终端设备1由第二节点进行调度。
需要特别说明的是，若是第二节点与第一节点之间传输的数据包为PDCP PDU或IP PDU，则第一节点可以获知终端设备1由第一节点进行调度。
如果第二节点与第一节点之间传输的数据包类型为PDCP PDU，当第一节点从第二节点收到PDCP PDU时，就要把该PDCP PDU依次在RLC层处理、MAC层处理、PHY层处理后，经过射频功能发送给终端设备。因为MAC层负责调度，包含调度功能处理过程，所以该承载类型指示为PDCP PDU时，就可以隐含指示终端设备1由第一节点进行调度。承载类型指示为IP PDU的情况也是类似的，不再赘述。
如果第二节点与第一节点之间传输的数据包类型为MAC PDU，当第一节点从第二节点收到MAC PDU时，就要把该MAC PDU在PHY层处理，通过射频功能发送给终端设备。因为MAC层负责调度，包含调度功能处理过程，所以该承载类型指示为MAC PDU时，就可以隐含指示终端设备1已经由第二节点进行了调度。承载类型指示为PHY数据的情况也是类似的，不再赘述。
需要特别说明的是图9与图10所示的实施例可以单独使用，也可以结合使用，也可以与其它实施例组合使用，在此不再赘述。
如图11所示，为了更好的理解本发明，本发明还提供了另一个实施例，该实施例与图6所示的实施例类似，不同之处在于：
413c、第二节点对终端设备2的数据在MAC层调度功能处理，生成MAC PDU。
需要特别说明的是，本发明所说的调度功能处理可以为MAC层的调度功能处理，即包括下述至少一种功能或特性：逻辑信息映射功能、复用功能、解复用功能、调度信息报告、优先级处理、逻辑信道优先级或传输格式选择功能。当然，这仅是为了说明本发明技术方案所举的例子，本发明包括并不限于上述举例。
需要说明的是，MAC层的功能分为调度功能和HARQ功能，这种划分可以 是预先定义的，也是可以协议规定的，也可以是自定义的，在此不再赘述。
414c、第二节点向第一节点发送终端设备2的MAC PDU。
415c、第一节点收到该终端设备2的MAC PDU后，将终端设备2的MAC PDU经过MAC层的HARQ功能处理后，通过第一节点与终端设备2之间的无线链路发送给终端设备2。
如图12所示，为了更好的理解本发明，本发明还提供了另一个实施例，该实施例与图6所示的实施例类似，不同之处在于：
413d、第二节点对终端设备2在PHY层进行处理,生成PHY层数据。
具体的：该下行数据包经过第二节点的PDCP层处理、RLC层处理和MAC层的调度功能处理后，然后经过下述至少一种物理层功能处理后生成PHY层数据:
CRC功能功能、信道编码功能、物理层的HARQ处理功能、信道交织功能、扰码功能、调制或者层映射和预编码功能。
当然，这些仅是为了理解本发明所举的例子，本发明包括并不限于此。
414d、第二节点向第一节点发送终端设备2的PHY层数据。
415d、第一节点收到该终端设备2的PHY层数据后，将该PHY层数据经过第一节点的射频功能处理后，通过第一节点与终端设备2之间的无线链路发送给终端设备2。
416d、终端设备2接收第一节点发送的该第一节点处理后的数据。
本发明还提供了另一个实施例，该实施例与图12所示的实施例类似，不同之处在于，采用其他协议栈类型，比如，将PHY层划分两部分，PHY层功能中和终端设备2相关的功能保留在第二节点，PHY层功能中和终端设备2无关的功能下放到第一节点，这种架构相对于上述完整PHY层数据的方案，可以进一下降低Fronthaul带宽需求。
需要特别说明的是，经过MAC层调度功能处理，且未经MAC层HARQ功能处理后的PDU，在本发明中也称为MAC PDU。
需要特别说明的是，经过部分PHY层处理后的数据，在本发明中也称为PHY层数据。
图9至图12所示的方案，相较于现有技术，本发明提供的方案是根据每个终端设备的基本信息和/或者网络信息(比如Fronthaul传输网络负载)，动态确定该终端设备是集中式调度还是分布式调度。一个小区里的不同的终端设备，可以实现不同的调度方式(集中式调度、或分布式调度)。并且一个小区里的终端设备的调度方式可以随着终端设备或者网络信息(比如Fronthaul传输网络负载)发生变更，进而从而实现根据实际网络运行情况在系统性能和传输网络带宽需求之间平衡。
这样相比于背景技术提到的集中式调度架构，因为小区里某些终端设备采用分布式调度，传输网络带宽的需求就会降低。相比于背景技术提到的分布式调度架构，因为小区里某些边缘终端设备可以采用集中式调度，小区的系统性能将得到提升。
为了更好的理解本发明的技术方案，对本发明实施例进行进一步说明，例如将图4、图5或图9所示的实施例称为第一方法，将图6、图7、图10、图11或图12所示的实施例称为第二方法，在此，第一方法与第二方法可以单独使用，也可以结合使用，结合使用时，执行顺序可以不分先后。例如，图4所示实施例的方法可以与图6实施例所示的方法可以结合使用，具体情况如图8所示，图8中，图4所示的实施例执行在前，图6所示的实施例执行在后，这仅是为了说明本发明的技术方案所提供的例子，本发明包括并不限于此。

1301、当终端设备的基本信息和/网络信息发生变化后，第二节点与第一节点之间协商改变调度节点。
具体的，可以由第二节点向第一节点发送变更指示，第一节点返馈一个变更响应，反之亦然，也可以由第一节点向第二节点发送变更指示，第二节点反馈一个变更响应。
具体的网络信息所包括的内容可以参照上述实施例的介绍，终端设备的基本信息所介绍的内容也可以参照上述实施例的介绍，在此不再赘述。

也就是说，原来终端设备由第一节点调度变更为由第二节点进行调度；或者原来终端设备由第二节点进行调度变更为由第一节点进行调度。
为了进一步说明该实例，如图13所示，为本发明的进一步示例，当然这只是为了方便理解发本发明技术方案所举的例子，具体的调度方法是可以参照上述实施例的，在此不再赘述。
1304、第二节点接收SGW发送的下行数据。

1307、第一节点收到该终端设备2的MAC PDU后，将终端设备2的MAC PDU经过PHY层处理后，经过射频功能处理，通过第一节点与终端设备2之间的无线链路发送给终端设备2。
1308、终端设备2接收第一节点发送的该第一节处理后的数据。
本发明实施例提供的方案，通过并且一个小区里的终端设备的调度方式可以随着终端设备或者网络信息(比如Fronthaul传输网络负载)发生变更，发明提供的方案是根据每个终端设备的基本信息和/或网络信息(比如Fronthaul传输网络负载)，动态确定该终端设备是集中式调度还是分布式调度。一个小区里的不同的终端设备，可以实现不同的调度方式(集中式调度、或分布式调度)。进而实现系统性能和传输网络带宽需求之间平衡。
为了更好的理解本发明的技术方案，对本发明实施例进行进一步说明，图13所示的实施例可以单独使用，适用于终端设备的基本信息发生变化，需要重新确定调度节点的场景，也可以与其它实施例结合使用，例如将图4、图5或图9所示的实施例称为第一方法，将图6、图7、图10、图11或图12所示的实施例称为第二方法，在此，图13所示的方法与第一方和/或第二方法结合使用，结合使用时，第一方法和/或第二方法可以执行在前，图13所示的方法执在后。
