本申请实施例涉及通信领域，并且更具体地，涉及一种传输数据的方法、终端设备和网络设备。
背景技术
长期演进(Long Term Evolution，LTE)系统中的大部分数据信道采用的都是基于调度的数据传输方式。若终端设备向网络设备申请资源之后又有新的上行数据到来或终端设备上报的数据量仅仅只是待传输的部分，导致未上报的数据不能得到及时传输，从而增加了这部分数据的传输时延，系统传输性能较差。
发明内容

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
应理解，本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，简称为“GSM”)系统、码分多址(Code Division Multiple Access，简称为“CDMA”)系统、宽带码分多址(Wideband Code Division Multiple Access，简称为“WCDMA”)系统、通用分组无线业务(General Packet Radio Service，简称为“GPRS”)、长期演进(Long Term Evolution，简称为“LTE”)系统、LTE频分双工(Frequency Division Duplex，简称为“FDD”)系统、LTE时分双工(Time Division Duplex，简称为“TDD”)、通用移动通信系统(Universal Mobile Telecommunication System，简称为“UMTS”)、全球互联微波接入(Worldwide Interoperability for Microwave Access，简称为“WiMAX”)通信系统或未来的5G系统等。
特别地，本申请实施例的技术方案可以应用于各种基于非正交多址接入技术的通信系统，例如稀疏码多址接入(Sparse Code Multiple Access，简称为“SCMA”)系统、低密度签名(Low Density Signature，简称为“LDS”)系统等，当然SCMA系统和LDS系统在通信领域也可以被称为其他名称；进一步地，本申请实施例的技术方案可以应用于采用非正交多址接入技术的多载波传输系统，例如采用非正交多址接入技术正交频分复用(Orthogonal Frequency Division Multiplexing，简称为“OFDM”)、滤波器组多载波(Filter  Bank Multi-Carrier，简称为“FBMC”)、通用频分复用(Generalized Frequency Division Multiplexing，简称为“GFDM”)、滤波正交频分复用(Filtered-OFDM，简称为“F-OFDM”)系统等。
本申请实施例中的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。接入终端可以是蜂窝电话、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网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端设备等，本申请实施例并不限定。
本申请实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备可以是GSM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)，还可以是云无线接入网络(Cloud Radio Access Network，CRAN)场景下的无线控制器，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网络中的网络设备或者未来演进的PLMN网络中的网络设备等，本申请实施例并不限定。
图1是本申请实施例一个应用场景的示意图。图1中的通信系统可以包括终端设备10和网络设备20。网络设备20用于为终端设备10提供通信服务并接入核心网，终端设备10通过搜索网络设备20发送的同步信号、广播信号等而接入网络，从而进行与网络的通信。图1中所示出的箭头可以表示通过终端设备10与网络设备20之间的蜂窝链路进行的上/下行传输。
为了便于理解，下面将结合图2简单描述基于调度的上行数据传输方式100。如图2所述，该方法100包括：
S110，终端设备发起调度请求(scheduling request，SR)，用来通知网络终端有数据待传；
S120，网络设备根据终端设备的调度请求在相应的物理下行控制信道(Physical Downlink Control Channel，PDCCH)发送下行控制信息 (DownlinkControlInformation，DCI)，其中包含上行资源授权；
S130，终端设备根据网络设备发送的上行资源授权，在相应的上行资源传输上行数据，其中如果终端设备缓冲中还有剩余数据，则继续在该数据信道上传输缓存状态信息(buffer status report，BSR)；
S140，网络设备根据BSR进一步下发上行资源授权，以此类推，直到终端不再发起请求。
具体地，在终端设备端有一个事件产生，通常是上行有数据发送，已经放在了缓冲区里了，那么它需要为这些数据申请上行资源用于发送。它可以通过SR控制信道来发送调度请求，或者通过物理随机接入信道(Physical Random Access Channel，PRACH)，此时是采用竞争的方式发送调度请求；网络设备按照一定的调度原则，如果可以的话就会分配一些资源用于发送BSR信息，通过上行资源授权告诉终端设备；终端设备发送BSR告诉网络设备对应的逻辑信道组有多少数据要发送，上行调度是针对逻辑信道组而不是一个无线承载；然后网络设备对终端设备请求的资源情况，分配相应的资源，然后通过上行资源授权通知终端设备；终端设备在自己的逻辑信道根据一定的优先级原则，发送上行数据。
通常终端设备申请的资源大小只够用于传输终端设备告知网络设备的数据量，实际上还有一部分的数据缓存在终端设备但网络设备并不知道，因此，这部分数据量通常需要在下一次上报，网络设备然后再为这一部分数据分配资源，而这种情况下会导致这部分数据得不到及时的传输，增大了时延，尤其对于低延时业务来说，导致传输性能较低。
图3示出了本申请实施例的传输数据的方法200的示意性框图。如图3所示，该方法200包括：
S210，终端设备向网络设备发送第一控制信令，该第一控制信令用于请求该网络设备为已缓存的第一上行数据分配上行资源以及为该终端设备分配备用上行资源；
S220，该终端设备接收该网络设备发送的第二控制信令，该第二控制信令用于指示为该第一上行数据分配的上行资源和该备用上行资源；
S230，该终端设备在为该第一上行数据分配的上行资源上传输该第一上行数据；
S240，若该终端设备有缓存的第二上行数据，在该备用上行资源上向该 网络设备发送该第二上行数据，该第二上行数据为除该第一上行数据以外的上行数据。
具体地，在终端设备有数据需要发送时，终端设备通常需要向网络设备申请上行资源，例如，终端设备可以通过物理上行控制信道(Physical Uplink Control Channel，PUCCH)向网络设备上发送SR，网络设备可以在PUCCH上监测是否有终端设备的SR上报。终端设备不仅需要为网络设备上报的上行数据分配资源，还要为未上报的上行数据分配资源，也就是本申请实施例中的备用上行资源，进而网络设备不仅需要向终端设备指示为上报的上行数据分配的上行资源，还需要向终端设备指示为未上报的上行数据分配的备用上行资源，从而终端设备可以采用为上报的数据分配的上行资源传输上报的数据，若终端设备还缓存有除了上报的上行数据之外，采用该备用上行资源向网络设备发送未上报的上行数据。
因此，本申请实施例的传输数据的方法，能够提高系统传输性能。
用于指示为终端设备分配备用上行资源的信息也可以单独向网络设备发送。例如，虽然终端设备暂时没有数据需要发送，终端设备可以结合自身的状态向网络设备申请该备用上行资源，那么一旦有上行数据到来之后，即可采用申请的备用上行资源传输数据，本申请实施例并不限于必须有待传输的数据的场景。
可选地，在本申请实施例中，该第二上行数据为在该终端设备向该网络设备发送该第一控制信令之后缓存的上行数据，或该第二上行数据为在该终端设备向该网络设备发送该第一控制信令之前缓存的上行数据。
应理解，该备用上行资源可以用于传输在终端设备向网络设备发送第一控制信令之前未上报的数据，也可以用于传输在终端设备向网络设备发送第一控制信令之后到来的数据。举例来说，若终端设备有数据1和数据2到来，终端设备只向网络设备上报了数据1的存在，那么终端设备可以在网络设备分配的备用上行资源上传输数据2。若终端设备只有数据1到来，终端设备在向网络设备上报了数据1的存在之后，又有数据3到达终端设备，那么终端设备同样可以用该备用上行资源传输数据3。
可选地，在本申请实施例中，该第一控制信令包括第一信息和第二信息，该第一信息用于指示该网络设备为该第一上行数据分配上行资源，该第二信息用于指示该网络设备为该终端设备分配该备用上行资源。例如，该第一信 息可以是1bit，0表示不需要上行资源，1表示需要上行资源。该第二信息也可以是1bit，0表示不用分配该备用上行资源，1表示为终端设备分配该备用上行资源。本领域技术人员理解，采用几个比特位来指示是否分配该备用上行资源或是否需要上行资源可以提前约定好。网络设备还可以和终端设备提前协商好，采用第一控制信令的哪几个比特位作为第一信息，哪几个比特位作为第二信息。例如，假若第一控制信令是5bit，那么可以约定前3个bit是第一信息，后两个bit是第二信息。
可选地，在本申请实施例中，该第一控制信令包括第一信息，该第一信息用于指示该网络设备为该第一上行数据分配上行资源，该第一控制信令的传输格式用于指示该网络设备为该终端设备分配该备用上行资源。还可以采用第一控制信令的传输格式来指示终端设备是否需要网络设备为其分配该备用上行资源。该传输格式可以是指控制信令包括的比特数，也可以是指控制信令包括的内容等。例如，可以将包括某一固定比特数的第一控制信令看作是终端设备需要该备用上行资源。具体地，网络设备和终端设备可以提前约定好，若网络设备接收到该第一控制信令包括5比特，那么可以认为是该终端设备是需要网络设备分配该备用上行资源的。应理解，第一控制信令可以有多种传输格式，还可以是3比特或者其他。
可选地，在本申请实施例中，该第一控制信令为调度请求SR或缓存状态报告BSR。
通常，网络设备为每个终端设备分配一个专用的SR资源发送SR，该SR资源是周期性的，每n个子帧出现一次。终端设备需要通过SR告知网络设备是否需要上行资源以用于传输上行数据，网络设备接收到SR之后，给终端设备分配至少用于发送BSR的资源。
本领域技术人员理解，终端设备通过SR向网络设备请求上行资源时，通常只指明了其是否有上行数据需要发送，而没有指明自己需要发送多少上行数据。终端设备需要通过BSR告诉网络设备，其上行buffer里有多少数据需要发送，以便网络设备决定给该终端设备分配多少上行资源。也就是说，终端设备需要告诉网络设备至少部分逻辑信道的缓存状态。具体地，当如下事件发生时，将会触发BSR上报：1、终端设备的上行数据buffer为空且有新数据到达，例如：终端设备第一次发送上行数据。该BSR被称为“Regular BSR”；高优先级的数据到达，如果终端设备已经发送了一个BSR，并且正 在等待上行授权，此时有更高优先级的数据需要传输，则终端设备会触发BSR上报。该BSR被称为“Regular BSR”；终端设备周期性地向网络设备更新自己的buffer状态，网络设备为终端设备配置了一个timer，如果该timer超时，终端设备会触发BSR上报。该BSR被称为“Periodic BSR”；4、网络设备为终端设备配置了一个timer，当该timer超时且UE的任意一个逻辑信道里有数据可以发送时，将会触发BSR。该BSR被称为“Regular BSR”。只要上述任一触发事件发生，终端设备则需要向网络设备发送BSR。
应理解，这里的SR或BSR不同于现有的SR或BSR，这里的SR可能不再是只有1个比特了，可以包括多个比特位，例如，可以在SR中用2bit来指示至少部分逻辑信道的缓存状态。这里的BSR也可以包括至少一个bit，来指示是否需要网络设备为终端设备分配备用上行资源。
可选地，在本申请实施例中，该第一控制信令还可以包括终端设备建议的该备用上行资源的大小信息。网络设备可以直接根据终端设备建议的大小，分配该备用上行资源，也可以不按照终端设备建议的大小，由网络设备自己分配该上行资源多大，位置在哪。
可选地，在本申请实施例中，若该终端设备没有缓存除该第一上行数据以外的上行数据，该终端设备向该网络设备发送第三信息，该第三信息用于指示该网络设备该备用上行资源没有上行数据传输。
上述提到，若终端设备有未向网络设备上报的上行数据，那么网络设备就可以采用该备用上行资源去传输这部分上行数据。同样地，若终端设备没有未向网络设备上报的上行数据，该备用上行资源就可以不用。同时，终端设备还可以向终端设备通知该备用上行资源上没有数据传输，可以不用监测。网络设备也可以不用终端设备通知，自己监测是否有数据传输。具体地，终端设备可以采用物理信道或者媒体接入控制(Medium Access Control，MAC)层的数据信道向网络设备通知没有数据在备用上行资源上传输。
因此，本申请实施例的传输数据的方法，通过在为上报的上行数据分配上行资源的同时还为未上报的上行数据分配备用的上行资源，使得一旦有未上报的数据存在，就可以及时得到传输，从而不会造成这部分数据的延时，提高了系统传输性能。
图4示出了本申请实施例的传输数据的方法300的示意性框图。如图4所示，该方法300包括：
S310，网络设备接收终端设备发送的第一控制信令，该第一控制信令用于指示该网络设备为已缓存的第一上行数据分配上行资源以及为该终端设备分配备用上行资源；
S320，该网络设备向该终端设备发送第二控制信令，该第二控制信令用于指示该为该第一上行数据分配的上行资源和该备用上行资源；
S330，该网络设备在该为该第一上行数据分配的上行资源上接收该第一上行数据。
具体而言，若网络设备接收到第一控制信令，例如BSR，网络设备除了可以按照现有为上报的数据分配上行资源以外，还可以为终端设备分配一块备用上行资源。并可以与正常分配的上行资源一起指示给终端设备，终端设备即可以用该备用上行资源传输未上报的数据。
因此，本申请实施例的传输数据的方法，能够提高系统传输性能。
可选地，在本申请实施例中，该第一控制信令包括第一信息和第二信息，该第一信息用于指示该网络设备为该第一上行数据分配上行资源，该第二信息用于指示该网络设备为该终端设备分配该备用上行资源，该方法还包括：该网络设备根据该第一信息，确定为该第一上行数据分配上行资源；该网络设备根据该第二信息，确定为该终端设备分配该备用上行资源。
例如，该第一信息可以是1bit，0表示不需要上行资源，1表示需要上行资源。该第二信息也可以是1bit，0表示不用分配该备用上行资源，1表示为终端设备分配该备用上行资源。网络设备若解析到该第一控制信令中的第一信息为1，第二信息为1，则网络设备确定需要为终端设备既要分配正常的资源，又要分配备用资源。
可选地，在本申请实施例中，该第一控制信令包括第一信息，该第一信息用于指示该网络设备为该第一上行数据分配上行资源，该方法还包括：该网络设备根据该第一信息，确定为该第一上行数据分配上行资源；该网络设备根据该第一控制信令的传输格式，确定为该终端设备分配该备用上行资源。
该传输格式可以是指控制信令包括的比特数，也可以是指控制信令包括的内容等。同样地，若终端设备和网络设备提前约定好若第一控制信令的包括的比特数是5则认为是需要备用上行资源的，所以在网络设备解析到终端设备发送的第一控制信令包括5个比特，网络设备可以确定为终端设备分配 备用上行资源。
可选地，在本申请实施例中，该第一控制信令为调度请求SR或缓存状态报告BSR。
应理解，这里的SR或BSR不同于现有的SR或BSR，这里的SR可能不再是只有1个比特了，可以包括多个比特位，例如，可以在SR中用2bit来指示至少部分逻辑信道的缓存状态。这里的BSR也可以包括至少一个bit，来指示是否需要网络设备为终端设备分配备用上行资源。
可选地，在本申请实施例中，该方法还包括：该网络设备为该终端设备分配该备用上行资源。进一步地，该第一控制信令包括该终端设备期望的该备用资源的大小信息，该网络设备为该终端设备分配该备用上行资源，包括：该网络设备根据该大小信息，为该终端设备分配该备用上行资源。
可选地，在本申请实施例中，该网络设备在该备用上行资源上监测该终端设备是否有上行数据传输；若监测到有上行数据传输，该网络设备通过该备用上行资源接收第二上行数据，该第二上行数据为除该第一上行数据以外的上行数据。
上述提到，该第二上行数据为在该终端设备向该网络设备发送该第一控制信令之后缓存的上行数据，或该第二上行数据为在该终端设备向该网络设备发送该第一控制信令之前缓存的上行数据。
可选地，在本申请实施例中，该方法还包括：该网络设备接收该终端设备发送的第三信息，该第三信息用于指示该备用上行资源没有上行数据传输。
可选地，在本申请实施例中，该第三信息承载于媒体接入控制MAC层信令或物理层信令中。
因此，本申请实施例的传输数据的方法，通过在为上报的上行数据分配上行资源的同时还为未上报的上行数据分配备用的上行资源，使得一旦有未上报的数据存在，就可以及时得到传输，从而不会造成这部分数据的延时，提高了系统传输性能。
应理解，网络设备描述的网络设备与终端设备的交互及相关特性、功能等与终端设备的相关特性、功能相应。也就是说，终端设备向网络设备发送什么信息，网络设备相应地就会接收什么信息。为了简洁，在此不再赘述。
还应理解，在本申请的各种实施例中，上述各过程的序号的大小并不意 味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
