上行数据传输方法、装置及存储介质
相关申请的交叉引用
本申请基于申请号为201710051704.5、申请日为2017年01月20日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本公开涉及无线通信领域，尤其涉及一种上行数据传输方法、装置及存储介质。
背景技术
现有技术中长期演进系统(Long Term Evolution,LTE)的结构示意图，如图1所示，主要由三个设备组成：用户设备(User Equipment,UE)、核心网(Core Network,CN)和基站(Evolved Node B,eNB)，其中，核心网中的移动管理实体(Mobility Management Entity,MME)主要负责信令的传输，服务网关(Serving GetWay,SGW)主要负责数据的传输。UE和eNB的接口为Uu，eNB与核心网的接口为S1。
按照现在的协议规定，UE要与eNB通信，首先要接入该eNB，也就是发起随机接入过程。如图2所示，利用授权资源进行随机接入包括四个步骤，分别是：
步骤S1：UE向eNB发送前导序列，具体包括：UE通过系统信息或者无线资源控制(Radio Resource Control，RRC)信令获知用于随机接入的可用的前导序列码以及发送前导序列的时频位置，然后，在可用的资源内，随机选择前导序列和发送前导序列的时频位置，并发送给eNB。
步骤S2：eNB向UE发送随机接入响应，具体包括：通过随机接入前导序列采用的时频位置，推断UE可能采用的接入无线网络临时标志(Raccess Radio Network Temporary Identity，RA-RNTI)，并用RA-RNTI解码前导序列，当eNB成功解码出前导序列后，给UE回复随机接入响应，响应中携带上行授权等信息。
步骤S3：调度传输，包括：UE利用上行授权资源上发送上行数据，并携带UE的标识等信息。
步骤S4：上行数据解码，具体包括：eNB在上行授权资源上解析上行数据，确认UE，解决冲突，并发送竞争决议标识给UE。
但是，这个过程需要四个步骤，延时较长，而且非正交技术已经得到了各个公司的认可，所以，随机接入过程也得到了技术上的更新，简化为2个步骤。UE可在非授权的情况下，将数据发送给eNB。如图3，存在两个步骤，分别是：
步骤S11：UE发送前导序列，并在非授权资源内，选择非授权资源，发送上行数据；
步骤S12：eNB解析出来后回复响应或者数据。
这里，发送上行数据的资源采用的是非正交技术。与传统的随机接入过程不同，非授权的上行数据可能要多个用户进行竞争，其功率也要比现有的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)高，而且，非授权的上行数据还存在着发送失败率高的问题。

具体实施方式
以下结合说明书附图及具体实施例对本公开的技术方案做进一步的详细阐述。
如图4所示，本实施例提供一种上行数据传输方法，应用于终端中，包括：
步骤S110：利用非授权资源发送上行数据；
步骤S120：利用非授权资源发送上行数据失败后，利用授权资源发送 上行数据。
在本实施例中所述终端又称为UE，这里的UE可为手机、平板电脑或可穿戴式设备等人载终端，也可以为车载UE，还可以是物联网中的各种终端设备。
在步骤S110中利用非授权资源发送上行数据。这里的非授权资源为非授权的资源池内选择的传输资源。所述传输资源可包括传输频谱和/或传输时隙等。通常，在步骤S110中发送所述上行数据可包括：直接选择非授权资源进行上行数据发送，还可包括：利用非授权资源发送前导序列，在发送完前导序列的发送时刻对应的传输时间间隔内发送至少一次所述上行数据。
在步骤S120中会在发送完所述前导序列之后，可以发送一次或多次上行数据。在本实施例中为了确保上行数据的发送成功，当需要发送多次利用非授权资源发送上行数据失败时，终端会自动转而利用授权资源重新发送所述上行数据。对于用户而言，终端转而利用授权资源发送所述上行数据是透明的，而对于用户而言相对于是发送成功了，显然减少了上行数据发送失败的失败提醒概率，终端自动转而利用授权资源进行发送，也相对于终端再次选择非授权资源进行发送，提升了发送成功率。
具体的如，所述步骤S120可包括：
基于目标接收功率递增方式利用非授权资发送所述上行数据，其中，第n+1次上行数据的目标接收功率大于第n次上行数据的目标接收功率；所述n为不小于1的正整数。例如，基于目标接收功率递增方式，利用非授权资源发送多次，例如，N次所述上行数据。所述n为小于所述N的正整数；所述N为不小于2的正整数。所述N的取值最小2，具体可为3、4或5等取值。这里的N的取值可为终端和基站预先协商的，也可以预先定义在终端中，当然，所述N也可以是随机生成的，也可以是根据当前的无 线环境动态决定的。这里的无线环境动态决定所述N可包括：
动态侦听所述非授权资源的使用状况，获得侦听结果；
根据所述侦听结果，确定所述N。例如，当所述侦听结果表明当前时刻以前S个传输时隙或传输子帧都被占用或被占用的比例为预设比例，则所述N为第一预设值，若未本占用所述N为第二预设值。所述第一预设值不等于所述第二预设值，这里仅是简单举例，具体实现还有很多种方式，总之，可以根据侦听结果确定所述N。
在本实施例中，会采用目标接收功率递增方式进行多次上行数据发送。这里的目标接收功率递增方式，为以提升基站接收到所述上行数据的接收功率为目的进行发送功率调整的上行数据发送方法。例如，终端会在前后两次的发送过程中，以接收功率递增的方式确定目标接收功率，然后根据目标接收功率与发送功率之间的对应关系或计算函数，得出本次的发送功率，利用得到的本次发送功率发送所述上行数据。根据目标接收功率确定本次的发送功率的过程中，涉及到本次发送的路损功率。这里的路损功率可为通过信道估计测量的，也可以是预先给定的一个路损值。本次的发送功率可为目标接收功率与所述路损值之和。当然，在具体实现时，还可能引入修正因子，在目标接收功率与所述路损值之和的基础上，通过修正因子，再次校正所述发送功率，从而获得更加精确的发送功率，同时确保基站的目标接收功率是逐次递增的。
这样的话，后一次上行数据的目标接收功率将高于前一次上行数据的目标接收功率。发送功率提升了，则基站(eNB)成功接收所述上行数据的概率就增加了，从而就能够提升所述上行数据的发送成功率。且由于开始采用较低的目标接收功率，则可以减少因为过高的目标接收功率，对其他终端或基站的通信的干扰，降低总体的无线干扰。
在本实施例中所述方法还包括：获取最大目标接收功率，当确定出当 前目标接收功率大于所述最大目标接收功率时，基于所述最大目标接收功率发送本次发送所述上行数据；若前一次发送的目标接收功率已经等于所述最大目标接收功率，则停止本次所述上行数据的发送，利用非授权资源或授权资源重新发送前导序列，重新进行随机接入。
在一些实施例中所述终端的功率发射器都有其发射功率的最大值，若当前基于当前目标发送功率确定出的当前发送功率大于功率发射器的最大发送功率时，利用所述最大发送功率发送所述上行数据，若本次发送再次失败，则停止下一次的上行数据发送，重新进行随机接入或转而利用所述授权资源重发所述上行数据。
在一般情况下，若基站成功接收了所述上行数据并解码了所述上行数据，则基站会向终端发送下行通知，若终端未接收到所述下行通知，则可以多次重复发送所述上行数据，直至满足预设条件则停止或暂停利用所述非授权资源发送所述上行数据。
显然，可以功率递增的方式发送上行数据，这种方式，一方面首先基于较小的目标功率发送上行数据失败时，通过目标接收功率的增大，可以提升上行数据的发送成功率；另一方面，没有一开始就基于最大的目标接收功率发送，可以减少无线信号的相互干扰问题。显然，通过功率递增的方式，可以提升利用非授权资源发送上行数据的成功率。
具体地如，如图5所示，所述步骤S110可包括：
步骤S111：利用如下公式，确定所述上行发送的当前目标接收功率；
ReceivedTargetPower＝
InitialReceivedTargetPower+(TRANSMISSION_COUNTER–1)*powerRampingStep；
其中，所述ReceivedTargetPower为当前目标接收功率；初始目标接收功率所述InitialReceivedTargetPower为第一次发送所述上行数据的初始目标接收功率；所述TRANSMISSION_COUNTER为发送所述上行数据的次 数；所述powerRampingStep为接收功率递增步长；
步骤S112：基于所述当前目标接收功率发送所述上行数据。
在本实施例中确定了所述初始目标接收功率，这里的初始目标接收功率和所述接收功率递增步长可预先存储终端中，也可以是所述终端从所述基站接收的。例如，基站通过RRC信令或系统消息或专有信令下发的所述初始目标接收功率，或，基站和终端预先协商的发送功率。所述系统消息或所述RRC信令或所述专用消息，携带有所述初始目标接收功率和/或所述接收功率递增步长；所述RRC信令包括RRC连接重配置信令、RRC连接释放信令、RRC连接建立信令或RRC连接重建立信令。
在一些实施例中，所述终端和基站之间还可协商最大发送次数，即协商所述TRANSMISSION_COUNTER的最大值。这样的话，基站就可以控制终端利用非授权资源发送上行数据的最大目标接收功率，以免过滤过大导致的无线干扰。当然，所述终端和基站之间可以直接预定义或协商最大目标接收功率，达到发送功率限制的方法。这里的TRANSMISSION_COUNTER也可以从系统消息、RRC信令或专有消息中接收。
这里的步骤S112可包括：
根据当前目标接收功率与当前发送功率的对应关系或转换函数，计算出当前的发送功率，利用当前的发送功率发送所述上行数据。
在一些实施例中，所述步骤S120可包括：当所述上行数据的发送状况满足预设条件时，利用授权资源发送上行数据。
为了确保成功发送所述上行数据，所述终端会监控所述上行数据的发送状况。例如，基站接收到上行数据时，就会发送下行通知，若未接收到下行通知，则终端可以确定上述数据暂时未发送成功或未被基站成功解码，需要继续发送所述上行数据。当然，所述终端还可以监控所述上行数据的 发送次数。当然，所述终端还可以根据当前时间，确定当前时间与发送所述前导序列的发送时间是否属于同一个传输时间间隔内，在未成功发送所述上行数据的情况下，确定是否继续利用非授权资源发送所述上行数据，或进行下一次的随机接入。这里的随机接入可以为如图2所示的利用授权资源的随机接入，或如图3所示的利用非授权资源的随机接入。
满足所述预设条件的方式有多种，以下提供几种可选方式：
可选方式一：
所述步骤S120可包括：
当利用非授权资源发送所述上行数据后，在预定时间内未接收到基站返回的上行通知或随机接入响应，则利用授权资源发起随机接入，并利用随机接入获得所述授权资源重新发送所述上行数据。
例如，当第m次前导序列和对应于所述第m次前导序列的所述上行数据均发送失败时，利用授权资源进行第m+1次随机接入并通过随机接入获取的收钱资源发送所述上行数据，其中，所述m为不小于1的正整数。在本实施例中若第m次前导序列和第m次前导序列对应的上行数据发送均失败，则所述终端在指定时间范围内会接收不到基站对于所述前导序列或上行数据的任何反馈，则终端可以确定出前导序列及上行数据均发送失败，则此时可以利用授权资源，进行下一次的随机接入。在本实施例中优选可为利用授权资源进行随机接入，以减少利用非授权资源进行再次上行数据发送的失败。
可选方式二：
所述步骤S120可包括：
若利用非授权资源发送所述上行数据后，收到了基站发送的携带有上行授权信息的随机接入响应时，利用上行授权信息指示的授权资源发送上行数据。
当在第m次前导序列对应的传输时间间隔内一次或多次所述上行数据均发送失败时，接收基站利用授权资源返回的随机接入响应，利用所述随机接入响应进行随机接入。
基站接收到终端发送的前导序列，但是没有成功接收前导序列对应的上行数据，则基站会向终端发送随机响应；则终端会接收到随机接入响应，此处的随机接入响应是基站利用授权资源发送的，并携带上行授权信息。这里的上行授权信息可为指示基站调度给终端的授权资源的指示信息，进而所述终端可以利用所述上行授权信息指示的授权资源，利用所述上行资源，完成随机接入和上行数据的传输。
可选方式三：
所述步骤S120可包括：
若利用非授权资源发送所述上行数据的发送次数达到预设次数，重新发起随机接入并在所述授权资源上发送上行数据。在本实施例中相当于设置了一次前导序列发送对应的利用非授权频谱发送上行数据的最大发送次数，以免终端过多次数发送依然不成功，导致的电能的消耗，以减少终端的功耗，延长移动终端的待机时长。
作为本实施例的进一步改进，所述方法还包括：
接收基站发送的系统消息或RRC信令或专用消息，其中，所述系统消息或RRC信令中携带有所述预设次数；所述RRC信令包括RRC连接重配置信令、RRC连接释放信令、RRC连接建立信令或RRC连接重建立信令。
这里的系统消息可为广播消息或组播消息或单播消息。所述RRC信令或专用信令，也可以为采用广播、组播或单播的方式发送的。
可选方式四：
所述步骤S120可包括：
当上一次发送失败利用非授权资源的所述上行数据的发送功率达到功 率阈值时，利用授权资源重新进行随机接入并在所述授权资源上发送上行数据。在本实施例中若上行数据的目标接收功率已经达到功率阈值，表明上一次发送失败的上行数据的目标接收功率是允许的最大目标接收功率时，此时没有可能再利用目标接收功率递增方式再次提升上行数据发送的目标接收功率，为了减少无效率的发送，在本实施例中会利用授权资源或非授权资源进行下一次随机接入。
如图6所示，本实施例提供一种上行数据传输方法，应用于终端中，包括：
步骤S210：利用非授权资源发送前导序列；
步骤S220：在所述前导序列发送时刻对应的传输时间间隔内，发送上行数据；
步骤S230：当预设时间内接收到携带有上行授权信息的随机接入响应时，采用所述上行授权信息指示的授权资源，重新发送所述上行数据。
本实施例提供的上行数据传输方法，依然是应用于UE中的方法。
在步骤S210可包括：首先利用非授权资源发送前导序列。在发送完所述前导序列之后就发送上行数据，通常所述上行数据的发送是与所述前导序列的发送时刻位于一个传输时间间隔内。故在步骤S220中将在发送前导序列的同一个传输间隔内，发送所述上行数据。
若前导序列发送成功，而所述上行数据发送失败或基站解码所述上行数据失败，则所述基站会发送随机接入响应，且此时随机接入响应中携带有上行授权信息。该上行授权信息可用于标识调度该终端的授权资源的标识信息。
这样的话，终端就不用再次发送前导序列，减少前导序列的发送次数，减少前导序列发送所需的功耗。
为了确保上行数据的发送成功，在步骤S240中所述终端会利用指示的 授权资源重新发送所述上行数据，以确保基站成功接收所述上行数据。
进一步地，所述方法还包括：
步骤S240：当在预设时间内未接收基站发送的所述随机接入响应或下行通知时，利用非授权资源或授权资源重新发起随机接入，其中，所述下行通知为基站在成功接收到所述前导序列和所述上行数据发送的信息。
在本实施例中所述终端依然利用非授权资源发送前导序列，在步骤S320依然是发送上行数据。在发送完所述前导序列和/或所述上行数据之后，终端开始计时，并在计时对应的预设时间内接收基站发送的信息，这里的基站发送的信息包括针对于所述前导序列的随机接入响应或下行通知，
在本实施例中所述终端在预定时间内未接收到所述下行通知或随机接入响应之后，将利用非授权资源或授权资源，重新发起随机接入，在本实施例中优选采用授权资源进行随机接入。
如图7所示，本实施例提供一种上行数据传输方法，应用于基站中，包括：
步骤S310：检测终端利用非授权频谱发送的前导序列；
步骤S320：检测所述终端发送的上行数据，其中，所述上行数据，是所述终端在所述前导序列发送时刻对应的传输时间间隔内发送的；
步骤S330：当所述前导序列正确解码而所述上行数据未正确解码时，在预设时间内利用授权资源向所述终端发送携带有上行授权信息的随机接入响应，其中，所述上行授权信息用于指示调度给所述终端的授权资源；
步骤S340：在所述上行授权信息指示的授权资源上，接收所述终端发送的上行数据。
本实施例是应用于基站中。基站会在非授权资源上检测用于随机接入的前导序列和/或上行数据，若检测到利用非授权资源发送的前导序列，但 是没有在非授权资源上接收到该终端的上行数据，或未成功解码该终端利用非授权资源发送的上行数据，则向终端发送随机接入响应。这里的随机接入响应是利用授权资源发送的，且携带有上行授权信息，向终端指示调度给其重新发送上行数据的授权资源，这样会促使终端转而利用授权资源发送上行数据，从而提升上行数据的发送成功率。

在一些实施例中，所述装置还包括：

所述第二发送单元120，配置为当利用非授权资源发送所述上行数据的发送状况满足预设条件时，利用授权资源发送上行数据。

以下结合上述任意实施例提供几个具体示例：
示例1
UE发送利用非授权资源发送上行数据时，采用功率递增的功率控制方法。
当UE第一次利用非授权资源发送的上行数据时，按照初始目标接收功率(对应于初始目标接收功率)发送上行数据。如果第一次不成功，那么UE再次利用非授权资源发送上行数据时，需要再增加发射功率。以此类推。每次发送不成功，就增加发射功率。
例如，初始目标接收功率为InitialReceivedTargetPower，每次递增的接收功率补偿为powerRampingStep，那么，发送TRANSMISSION_COUNTER次非授权的上行数据时，目标接收功率ReceivedTargetPower为：ReceivedTargetPower＝InitialReceivedTargetPower+(TRANSMISSION_COUNTER–1)*powerRampingStep。
其中，初始目标接收功率、递增功率可以由系统信息广播，也可以由RRC信令配置，包括无线连接控制重配置(RRCConnectionReconfiguration)信令、无线连接控制释放(RRCConnectionRelease)信令、无线连接控制建立(RRCConnectionSetup)信令、无线连接控制重建立(RRCConnectionReestablishment)信令，或者新定义的消息等。
示例二：
如果UE利用非授权资源发送上行数据时，发射功率不够，会导致基站无法监测到非授权的上行数据。这种情况下，基站可能会成功监测出前导序列，但是无法监测出上行数据来。但是，基站可以针对前导序列回复随机接入响应，那么，非授权的上行发送过程可以转为传统的随机接入过程。
当UE发送非授权的上行数据失败，UE随后发起传统的随机接入过程。如图11所示，包括：
步骤S21：UE发送前导序列，并在非授权的资源内，选择资源，发送上行数据；
步骤S22：eNB解析前导序列，但是没有监测出非授权上行数据，回复 随机接入响应，并携带上行授权；
步骤S23：UE在上行授权资源上重新传输上行数据，并携带UE的标识等信息；
步骤S24：eNB在上行授权资源上接收并解析上行数据，确认UE，解决冲突，并发送竞争决议标识给UE。这里的上行授权资源可如图11中所示的PUSCH重新发送的上行数据。
上述随机接入响应，能被多个利用同一个前导序列进行随机接入的UE接收到，若步骤S23中UE携带UE的标识，则在步骤S24中基站在授权资源上接收到多个UE发送的上行数据时，可以根据提取的UE的标识，确定最终解码哪一个UE的上行数据，从而达到确认发送UE及冲突解决的目的。
示例三：
如果UE利用非授权资源发送上行数据时，发射功率不够，会导致基站无法监测到非授权的上行数据。这种情况下，基站可能也没有成功监测出前导序列，基站无法回复随机接入响应，那么，非授权的上行发送过程可以转为传统的随机接入过程。
当UE发送非授权的上行数据失败达到n次，其中n次为系统信息广播或者RRC信令配置，UE随后发起传统的随机接入过程。
或者UE发送非授权的上行数据达到最大发送功率后仍然失败，UE随后发起传统的随机接入过程。
流程图如图12所示，包括：
步骤S31：UE发送前导序列，并在非授权的资源内，选择资源，发送上行数据；eNB解码失败，不仅没有解码出前导序列，而且也没有监测出非授权上行数据，不回复响应；
步骤S32：UE等待随机接入响应失败，随后发起传统的随机接入过程。UE再次选择前导序列，并发送给eNB；
步骤S33：eNB监测出前导序列，恢复响应消息，并携带上行授权等信息；
步骤S34：UE在上行授权的资源上发送上行数据，并携带UE的标识等信息；这里的上行授权资源可如图11中所示的PUSCH重新发送的上行数据；
步骤S35：eNB在上行授权的资源上解析上行数据，确认UE，解决冲突，并发送竞争决议标识给UE。这里的UE确认和冲突解决，可以参见前述示例。
