具体实施方式
LTE系统的随机接入分为竞争随机接入和非竞争随机接入两种。
竞争随机接入用于以下目的：终端初始接入；RRC(Radio Resource Control，无线资源控制)连接重建；切换；非同步状态下RRC连接态时下行数据到达；RRC连接态时上行数据到达；RRC连接态时的定位。
图1为竞争随机接入过程示意图，其过程如图1所示，主要分为四步：
Msg1：UE(User Equipment，用户设备)选择随机接入preamble(随机接入前导码)和PRACH(Physical Random Access Channel，物理随机接入信道)资源并利用该PRACH资源向基站发送所选的随机接入preamble。
Msg2：基站接收到preamble，计算TA(Time Alignment，定时提前量)，并向UE发送随机接入响应，随机接入响应中包含该定时提前量信息和针对 Msg3的UL grant(上行授权)，以及网络侧分配的临时C-RNTI。承载Msg2调度消息的PDCCH(Physical Downlink Control Channel，物理下行控制信道)用RA-RNTI(Random Access-Radio Network Temporary Identity，随机接入无线网络临时识别)加扰，RA-RNTI在10ms窗内与发送Msg1的时频资源唯一对应；另外Msg2中还携带preamble ID，UE通过RA-RNTI和preamble ID确定该Msg2是与其发送的Msg1对应的。
Msg3：UE在Msg2指定的UL grant上发送上行传输，不同随机接入原因Msg3上行传输的内容不同，比如对于初始接入，Msg3传输的是RRC连接建立请求。
Msg4：竞争解决消息，UE根据Msg4可以判断随机接入是否成功。对于初始接入UE，竞争解决成功后临时C-RNTI自动转化为UE在该小区的唯一UE标识C-RNTI。
非竞争随机接入用于切换；下行数据到达；定位和获取上行定时。
图2为非竞争随机接入过程示意图，如图2所示，主要分为三步：
Msg0：基站向UE分配用于非竞争随机接入的专用preamble以及随机接入使用的PRACH资源。
Msg1：UE根据Msg0的指示，在指定的PRACH资源上向基站发送指定的专用preamble。基站接收到Msg1后根据Msg1计算上行定时提前量TA。
Msg2：基站向UE发送随机接入响应，随机接入响应中包含定时提前量信息、后续上行传输资源分配UL grant，定时提前量用于UE后续上行传输的定时关系。
在LTE系统中，终端在初始接入以及其他一些没有上行传输资源分配的情况下要发起传输，首先需要进行随机接入过程。传输接入时还需要通过随机接入过程分配小区内唯一标识C-RNTI才能开展后续数据传输过程，而LTE系统随机接入过程时延特别不利于新一代5G系统低时延的需求。基于此，本公开实施例中提供了一种终端发起的数据传输方案，由终端向网络侧发送 与终端标识关联的序列码，网络侧在接收到该序列码后，与终端使用与终端标识关联的序列码和/或终端标识进行数据传输。下面结合附图对本公开的具体实施方式进行说明。
在说明过程中，将分别从终端与网络侧的实施进行说明，然后还将给出二者配合实施的实例以更好地理解本公开实施例中给出的方案的实施。这样的说明方式并不意味着二者必须配合实施、或者必须单独实施，实际上，当终端与网络侧分开实施时，其也各自解决终端侧、网络侧的问题，而二者结合使用时，会获得更好的技术效果。
图3为在终端侧的终端发起的数据传输方法实施流程示意图，如图所示，包括：
步骤301、在终端上向网络侧发送与终端标识关联的序列码，所述终端标识和/或序列码是该终端的唯一性标识；
步骤302、在网络侧接收到该序列码后，与网络侧使用与终端标识关联的序列码和/或终端标识进行数据传输。
图4为在网络侧的终端发起的数据传输方法实施流程示意图，如图所示，包括：
步骤401、接收终端向网络侧发送的与终端标识关联的序列码，所述终端标识和/或序列码是该终端的唯一性标识；
步骤402、在网络侧接收到该序列码后，与终端使用与终端标识关联的序列码和/或终端标识进行数据传输。
在步骤302、402实施中，网络侧在接收到序列码后，与终端使用与终端标识关联的序列码和/或终端标识进行数据传输，这里的数据传输包含了上下行传输的情况。
在上行传输的情况下，在终端侧发送序列码后，接收网络侧的上行资源分配，并在分配的资源上发送上行传输。该方案将会通过实施例2、3、4等进行说明。
在下行传输的情况下，如果基站直接识别终端，可以立即发起下行传输，该方案将会通过实施例1等进行说明；
也可能是基站直接调度和发送下行传输，例如实施例6，TA的发送只是 一个下行传输发送。
下面先对实施中的终端标识及序列码进行说明。
终端标识：指终端在一定网络区域内的标识，区别于LTE系统在一个小区范围内可识别的C-RNTI，终端标识可以是全网或在特定运营商下或在包含多个TP(Transmission Point，传输点)的区域范围内可识别的标识。终端标识又分为高层终端标识和物理层终端标识(如C-RNTI即为LTE系统的物理层终端标识)，高层终端标识(higher layer UE ID)长度较大，在上述规定范围内唯一；物理层标识(physical UE ID)受限于其长度，可能在上述规定范围内唯一或需要与其他信息共同唯一标识终端。
上述物理层终端标识(physical UE ID)也可以为空口终端标识等类似的名称，只要其用途是在空口传输中采用本公开实施例提供的类似方式识别终端。而不仅限于上述几种终端标识。
与终端标识关联的序列码：使用该序列码向网络侧发起传输，区别于LTE系统UE共享并随机选择的preamble码和需要网络侧专用信令指示分配的专用preamble码，该序列码设计为与终端标识直接关联。有以下几种可能的用法：
1、终端标识是该终端的唯一性标识，序列码是该终端的唯一性标识；
物理层终端标识和序列码sync1都为终端特有，网络侧可以通过任何一个唯一识别终端；
2、终端标识与一个序列码组合后是该终端的唯一性标识；
物理层终端标识+序列码sync1组合形成终端特有标识，网络侧通过检测sync1和物理层终端标识唯一识别终端；
3、终端标识与多个序列码组合后是该终端的唯一性标识，多个序列码之间存在关联关系。
多个序列码与终端标识关联，序列码之间是相互关联的，如sync1用于初始序列码发送，sync3用于与后续上行传输一起发送。
实施中，关于终端标识与序列码的关联关系可以是终端与网络侧预知的；或，终端标识与序列码的关联关系是通过终端与网络侧的交互获知的。
下面就结合实例对这两种方式的实施进行说明。在说明过程中，为方便 表述将临时使用的physical UE ID简称为临时physical UE ID，在为了更恰当的表述physical UE ID与序列码的对应关系时，也会将其表述为对应的physical UE ID。
1、终端标识与序列码的关联关系是终端与网络侧预知的。
1)终端标识是该终端的唯一性标识，序列码是该终端的唯一性标识时，序列码用于供网络侧根据关联关系识别该终端的终端标识，终端标识用于供网络侧进行数据传输；
具体的，physical UE ID、sync1都为终端特有，网络侧可以通过任何一个唯一识别终端。
终端在需要发起传输时，在上行信道上发送sync1序列；网络侧传输点接收、识别sync1并确定与之对应的physical UE ID，后续使用该physical UE ID与终端进行数据传输。
实施例1：
本实施例中，physical UE ID、sync1都为终端特有。图5为实施例1实施流程示意图，如图所示，可以包括如下步骤：
步骤501：终端在上行信道上发送sync1。
该sync1唯一标识一个终端，并与一个physical UE ID对应；
步骤502：网络侧传输点识别终端，并确定其对应的physical UE ID。
网络侧传输点接收、识别sync1并确定与之对应的physical UE ID。
步骤503：网络侧传输点与终端使用该physical UE ID和sync1(可能包括sync3)进行空口传输。
后续网络侧和终端使用该physical UE ID进行数据调度和传输。
2)终端标识与一个序列码组合后是该终端的唯一性标识时，序列码用于供网络侧为该终端分配临时使用的终端标识，临时使用的终端标识用于供网络侧分配传输所述终端标识的资源；
具体的，physical UE ID和sync1组合唯一确定终端时，终端在需要发起传输时，在上行信道上发送sync1序列；网络侧传输点接收、识别sync1并用临时physical UE ID分配上行资源；终端在网络侧分配的上行资源上进行上行传输并携带physical UE ID；网络侧传输点接收该上行传输并唯一识别该终 端，具体实施中可以对终端进行必要的反馈。
实施例2
本实施例中，通过physical UE ID和sync1组合确定终端。图6为实施例2实施流程示意图，如图所示，可以包括如下步骤：
步骤601：终端在上行信道上发送sync1.
对于终端来说，该sync1与一个physical UE ID组合唯一确定终端，但该sync1本身可能与多个physical UE ID对应。
步骤602：网络侧传输点使用临时physical UE ID分配上行资源。
网络侧传输点接收、识别sync1并用临时physical UE ID分配上行资源，该临时physical UE ID可以与sync1和/或其发送时频资源位置关联，如从sync1可能对应的physical UE ID中随机选择一个作为临时physical UE ID；
步骤603：终端在网络侧分配的上行资源上进行上行传输，并携带该终端的physical UE ID，具体实施中还可以发送与该physical UE ID对应的sync3；
步骤604：网络侧传输点接收该上行传输并通过sync1和终端发送的physical UE ID唯一识别该终端，具体实施中网络侧传输点还可以对终端进行必要的反馈。例如，反馈确认或失败。
步骤605：网络侧传输点与终端使用该physical UE ID和sync1(可能包括sync3)进行空口传输。
3)终端标识与多个序列码组合后是该终端的唯一性标识，多个序列码之间存在关联关系时，第一个序列码用于供网络侧为该终端分配临时使用的终端标识，临时使用的终端标识用于供网络侧分配传输所述终端标识及第二个序列码的资源，第二个序列码及终端标识用于供网络侧唯一识别该终端的终端标识；
具体的，在physical UE ID和sync3组合唯一确定终端时，终端在需要发起传输时，在上行信道上发送sync1序列；网络侧传输点接收、识别sync1并用临时physical UE ID分配上行资源，其中sync1与sync3具有对应关系；终端在网络侧分配的上行资源上进行上行传输，携带physical UE ID，同时发送上行序列sync3；网络侧传输点接收该上行传输并根据physical UE ID和sync3组合唯一识别该终端，可以对终端进行必要的反馈。
实施例3
本实施例中，physical UE ID和sync3组合唯一确定终端。图7为实施例3实施流程示意图，如图所示，可以包括如下步骤：
步骤701：终端在上行信道上发送sync1；
步骤702：网络侧传输点使用临时physical UE ID分配上行资源。
网络侧传输点接收、识别sync1并用临时physical UE ID分配上行资源，该临时physical UE ID可以与sync1和/或其发送时频资源位置关联，如sync1与一个临时physical UE ID唯一对应；
步骤703：终端在网络侧分配的上行资源上进行上行传输并携带该终端的physical UE ID，同时在该上行TTI(Transmission Time Interval，传输时间间隔)上发送上行序列sync3。
步骤704：网络侧传输点接收该上行传输，通过该上行传输携带的physical UE ID和同时在该上行TTI上发送的sync3，唯一确定终端，具体实施中网络侧传输点还可以对终端进行必要的反馈。例如，反馈确认或失败。
在步骤703、704中，TTI是作为一个上行传输单位来进行表述的，可以理解为类似于LTE中描述的“一个上行子帧”。这样表述的目的主要是为了强调上行传输和sync3在相同的上行传输单位发送。
步骤705：网络侧传输点与终端使用该physical UE ID和sync1(可能包括sync3)进行空口传输。
4)终端标识与多个序列码组合后是该终端的唯一性标识，多个序列码之间存在关联关系时，第一个序列码用于供网络侧确定约定的传输第二个序列码的资源，第二个序列码及第一个序列码用于供网络侧唯一识别该终端的终端标识。
在通过sync1和sync3组合唯一确定终端，且与一个physical UE ID对应时，终端在需要发起传输时，在上行信道上发送sync1序列；网络侧传输点接收、识别sync1，(网络侧可以根据需要分配或不分配上行传输资源)；终端在与sync1传输位置具有约定时序关系的位置(如至少相隔两个TTI的上行TTI)发送sync3(根据需要可能发送上行数据传输)；网络侧传输点接收sync3，根据sync1和sync3的组合唯一识别该终端。
实施例4
本实施例中，sync1和sync3组合唯一确定终端，且与一个physical UE ID对应。图8为实施例4实施流程示意图，如图所示，可以包括如下步骤：
步骤801：终端在上行信道上发送sync1；
步骤802：网络侧传输点使用临时physical UE ID分配上行资源。
网络侧传输点接收、识别sync1后，可以有以下两种方式：
方式1：网络侧传输点用临时physical UE ID为终端分配上行资源，该临时physical UE ID可以与sync1和/或其发送时频资源位置关联，如从sync1可能对应的physical UE ID中随机选择一个作为临时physical UE ID，该方式为图中示意的方式；
方式2：网络侧不向终端分配上行资源；
步骤803a：对应方式1：终端在网络侧分配的上行资源上进行上行传输并携带该终端的physical UE ID，同时在该上行TTI上发送上行序列sync3；
步骤803b：对于方式2：终端在与sync1具有确定时序关系的上行TTI(如相隔两个TTI的上行TTI)发送sync3。
具体实施中网络侧传输点还可以对终端进行必要的反馈。例如，反馈确认或失败。
在本步骤中，TTI是作为一个上行传输单位来进行表述的，可以理解为类似于LTE中描述的“一个上行子帧”。这样表述的目的主要是为了强调上行传输和sync3在相同的、或者不同但有时序关系的上行传输单位发送。
步骤804：网络侧传输点接收sync3，根据sync1和sync3的组合唯一识别该终端，也可通过步骤802、803的方式1进一步确定该终端的physical UE ID，步骤802中的临时physical UE ID释放。
2、终端标识与序列码的关联关系是通过终端与网络侧的交互获知的。
在终端侧上，在终端标识与序列码的关联关系是通过终端与网络侧的交互获知时，终端在第一个序列码可选资源池中选择一个序列码作为第一个序列码发送，该第一个序列码与一个临时使用的终端标识对应，所述临时使用的终端标识用于供网络侧分配传输所述终端标识及第二个序列码的资源，所述第一个序列码与所述第二个序列码之间存在关联关系，所述第二个序列码 及所述临时使用的终端标识用于供网络侧在确认终端接入网络后为该终端分配终端标识。
相应的，在网络侧，在终端标识与序列码的关联关系是通过终端与网络侧的交互获知时：
在接收到终端发送的第一个序列码后，根据第一个序列码与临时使用的终端标识的对应关系确定一个临时使用的终端标识；
根据该临时使用的终端标识为终端分配该终端传输终端标识及第二个序列码的资源，所述第一个序列码与所述第二个序列码之间存在关联关系；
接收到该终端在该资源上传输的终端标识及第二个序列码后，根据所述第二个序列码及所述临时使用的终端标识在确认终端接入网络后为该终端分配终端标识。
本实施例中，网络侧和终端尚未建立physical UE ID、序列码与终端对应关系的共识。这种情况下需要通过网络侧和终端的交互确定终端使用的physical UE ID、序列码。
具体是指在终端未获取唯一的高层UE ID时，如在网络侧对终端鉴权认证成功前未获取唯一的高层UE ID。
网络侧对终端鉴权认证成功后，网络侧为终端分配唯一的高层UE ID，该高层UE ID与特定的physical UE ID、序列码具有直接对应关系，使用该对应的physical UE ID和序列码进行后续数据传输即可，具体可参照1中终端标识与序列码的关联关系是终端与网络侧预知的实施的方式。也即，后续的使用时可以参考的，与之不同仅在于关联关系的获取方式不同，1为预知的，2为通过交互获知的。
具体过程可以为：由终端在sync1序列可选资源池中选择一个序列码作为sync1发送，该sync1码与一个临时physical UE ID对应；网络侧传输点接收sync1后，如果该sync1及其对应的physical UE ID未被其他终端占用，用该sync1对应的physical UE ID对该终端进行数据调度和传输，如果被占用，回复冲突指示，冲突指示中可携带延后发起接入的backoff参数。网络侧为该终端分配唯一的高层UE ID后或该终端接入网络失败后，本次接入使用的sync1码和对应的physical UE ID释放回资源池，供其他终端竞争使用。
可选地，该sync1与另一个序列码sync3一一对应。终端在发送上行传输的时候可以携带physical UE ID和发送sync3，供网络侧识别终端。
实施例5
图9为终端初始接入时通过交互获知关联关系的实施流程示意图，如图所示，可以包括如下步骤：
步骤901：终端在上行信道上发送sync1。
终端在sync1序列可选资源池中选择一个序列码作为sync1向网络侧发送。
步骤902：网络侧传输点使用临时physical UE ID分配上行资源。
网络侧传输点TP接收sync1并用与该sync1对应的临时physical UE ID为终端分配上行资源，physical UE ID可以是隐式或显式携带在资源分配命令中，显式是指physical UE ID直接为上行资源分配命令的一个域，隐式是指该physical UE ID作为扰码等附加在资源分配命令中，终端通过匹配滤波这类方式还原资源分配命令。
步骤903：终端在网络侧分配的上行资源上进行上行传输，并携带该终端的临时physical UE ID，具体实施中还可以发送与该physical UE ID对应的sync3；
终端在网络侧分配的上行资源上发起上行传输，上行传输携带与sync1对应的临时physical UE ID，上行传输内容包括终端接入网络所需的请求和身份信息等，终端可选地在上行传输相同TTI内发送sync3，该sync3与sync1、physical UE ID具有对应关系；
在步骤903中，TTI是作为一个上行传输单位来进行表述的，可以理解为类似于LTE中描述的“一个上行子帧”。这样表述的目的主要是为了强调上行传输和sync3在相同的上行传输单位发送。
步骤904：网络侧为终端鉴权认证和分配唯一高层UE ID；
网络侧传输点通过临时physical UE ID和/或sync3识别发起传输的终端，解出该终端发送的上行传输内容，进行鉴权认证等操作，确认终端接入网络，并分配高层UE ID，该高层UE ID与确定的physical UE ID、sync1、sync3(可选)对应。
步骤905：网络侧和终端使用步骤904获取的physical UE ID、sync1、sync3 (可选)进行数据传输。
实施中，临时physical UE ID和对应的sync1、sync3可以释放回资源池。也即，在为该终端分配终端标识后，可以进一步包括：
将所述第一个序列码、所述临时使用的终端标识以及所述第二个序列码释放回资源池；或，将所述第一个序列码以及所述临时使用的终端标识释放回资源池。
实施中，在网络侧，还可以进一步包括：
向终端命令用以触发终端发送所述序列码，所述序列码用于供网络侧进行上行定时估计。
相应的，在终端侧，还可以进一步包括：
在接到网络侧发送所述序列码的命令时，发送所述序列码，所述序列码用于供网络侧进行上行定时估计。
具体的，命令可以是物理层信令或层2控制信令。
实施例6：
在网络侧触发终端发送上行序列码获取上行定时这种场景下，主要是网络侧需要利用终端发送的上行信号或数据进行上行定时估计。可以按如下方式实施：
步骤一：网络侧传输点向终端发送命令触发终端发送sync1，该命令可以是物理层信令或层2控制信令，该信令携带physical UE ID和/或下行UE特有序列码(DL sync)；
步骤二：终端发送sync1；
步骤三：网络侧接收sync1利用sync1进行上行定时估计，并将上行定时命令TA发送给终端。
实施中，涉及多个序列码等的传输，在具体实施中可以按如下方式实施。
图10为序列码和上下行传输时序示意图，如图所示，假设终端在第一个sync1位置发送上行sync1传输，网络侧传输点在第一个箭头对应的位置向终端发送必要的上行资源分配，终端在第三个上行TTI发送上行传输和/或sync3。
在各实施例中，TTI是作为一个上行传输单位来进行表述的，可以理解为类似于LTE中描述的“一个上行子帧”。这样表述的目的主要是为了强调 上行传输和sync3在相同的、或者不同但有时序关系的上行传输单位发送。
基于同一发明构思，本公开实施例中还提供了一种终端发起的数据传输装置，由于这些装置解决问题的原理与上述终端发起的数据传输方法相似，因此这些装置的实施可以参见方法的实施，重复之处不再赘述。
图11为在终端侧的终端发起的数据传输装置结构示意图，如图所示，可以包括：
发送模块1101，用于在终端上向网络侧发送与终端标识关联的序列码，所述终端标识和/或序列码是该终端的唯一性标识；
终端传输模块1102，用于在网络侧接收到该序列码后，与网络侧使用与终端标识关联的序列码和/或终端标识进行数据传输。
实施中，所述终端标识与序列码的关联关系是终端与网络侧预知的；
