背景技术
随着智能终端的发展以及无线数据应用业务的丰富，无线通信网络中的数据用户数大幅增加。无线数据内容不再仅限于传统的文字或者图像，还越来越多的出现高清晰度视频、手机电视等多媒体业务内容，从而导致无线通信网络流量呈现爆炸式增长。移动互联网和物联网业务将成为移动通信发展的主要驱动力。
针对物联网，3GPP(The third Generation Partnership Project,第三代合作伙伴计划)标准组织制定了MTC(Machine Type Communication,机器类型通信)和NB-IoT(Narrow Band Internet of Things,窄带物联网)两个非常具有代表性的通信标准协议。针对移动互联网，3GPP标准组织最新制定了5G(5 Generation，第五代)NR(New Radio，新无线)通信标准协议。
按照上述通信标准协议，终端在没有数据需要发送或者接收时，会进入RRC(Radio Resource Control，无线资源控制)空闲状态(简称RRC_IDLE)，进而节省终端的功耗。终端在发送或者接收数据之前需要从RRC空闲状态进入RRC连接状态(简称RRC-CONNECT)状态，然后再进行数据的发送或者接收。终端从RRC空闲状态进入RRC连接状态会消耗终端的功耗以及系统资源。

具体实施方式
下文中将结合附图对本申请的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
图1为本申请一实施例的传输控制方法的流程示意图。如图1所示，该传输控制方法可以应用于终端中，该方法可以包括：
步骤S11、判断定时提前量(Timing Advanced，TA)的有效性。
步骤S12、在所述TA处于无效状态下，发起随机接入过程。
在本申请实施例中，终端发起随机接入过程能够将TA从无效状态更新为有效状态。需要说明的是，通过发起随机接入过程，仅是将TA从无效状态更新为有效状态的一种方式，也可以采用其他的方式更新TA的状态。此外，在TA处于无效状态，也可以不将TA从无效状态更新为有效状态，而是放弃在RRC空闲状态或非激活状态下利用第一类信道进行数据传输。
在一种实施方式中，终端接收到随机接入过程中第二消息(Msg2)。所述Msg2中包括终端的TA信息(假设标记为TA1)。
在一种实施方式中，终端在所述第一类信道上发送数据的提前量为TA1-TA2。其中，TA2可以由基站配置后发送给终端。
此外，也可以根据循环前缀(cyclic prefix，CP)确定TA2。
在一种实施方式中，根据循环前缀(cyclic prefix，CP)的长度确定TA2，可以采用多种方式，示例如下：
示例一：TA2＝1/2*CP长度。
示例二：TA2＝a*CP长度；其中，a的取值可以由基站配置后发给终端或者在终端中采用默认配置。
在一种实施方式中，如图2所示，该方法还包括：
步骤S13、在所述TA处于有效状态下，允许终端在无线资源控制(RRC)空闲状态或非激活状态(Inactive mode)下利用第一类信道进行数据传输。
在本申请实施例中，第一类信道的配置信息可以由基站在RRC连接状态通过RRC消息发送给终端。其中，在第一类信道上，终端可以在RRC空闲状态或非激活状态进行上行数据传输。此外，第一类信道占用的资源可以在时域上周期分布或者离散分布。
在RRC空闲状态或非激活状态下，如果TA处于有效状态，当终端有需要传输的上行数据时，可以利用第一类信道进行数据传输。通过判断TA有效性，终端能够实现在RRC空闲状态或非激活状态下，多次利用第一类信道进行数据传输。在TA有效状态下，不需要在建立RRC连接，即可进行数据传输，因此可以减少终端的功耗，节约系统资源。
在一种实施方式中，判断TA的有效性可以包括：在判断时刻判断满足特定条件，则判断所述TA处于无效状态。否则，TA处于有效状态。
在一种示例中，判断时刻位于下一个第一类信道的时域资源之前。在另一种示例中，判断时刻位于上一个第一类信道的时域资源之后。
在一种实施方式中，终端在判断时刻判断TA的有效性之前，可以先确定TA是否一直有效。当TA不是一直有效时，再开始判断TA的有效性。TA是否一直有效可以由基站通过信令通知终端。
在一种实施方式中，终端在判断时刻判断TA的有效性之前，可以先检查终端的服务小区或者驻留小区是否发生改变。如果终端的服务小区或者驻留小区发生改变，则表示TA处于无效状态。如果终端的服务小区或者驻留小区没有发生改变，再利用其他方式判断TA的有效性。
在本申请实施例中，判断TA有效性的方式可以包括多种，示例如下。
方式一：终端基于某些参数的测量值例如RSRP(Reference Signal Receiving Power,参考信号接收功率)等判断TA有效性。该方式中，如果判断时刻判断满足以下条件之一，终端的TA处于无效状态。否则，TA处于有效状态。
(1)在第一判断时刻集合中的至少N1个判断时刻判断第一测量值的变化量超过阈值；其中，N1为大于或等于1的整数。例如，如果N1等于1，则在第一判断时刻集合中的至少一个判断时刻判断第一测量值的变化量超过阈值，表示TA处于无效状态。其中，第一判断时刻集合可以由基站配置并且发送给终端，或者采用默认配置。
(2)在第一判断时刻集合中的最后N2个判断时刻判断第一测量值的变化量超过阈值；其中，N2为大于或等于1的整数。例如，如果N2等于1，则在第一判断时刻集合中的最后一个判断时刻判断第一测量值的变化量超过阈值，表示TA处于无效状态。其中，第一判断时刻集合中的最后一个判断时刻可以是第一判断时刻集合中距离下一个第一类信道资源的时域位置最近的判断时刻。
在本申请实施例中，所述第一测量值可以包括但不限于以下至少一个：参考信号接收功率(RSRP)；参考信号接收质量(Reference Signal Receiving Quality，RSRQ)；下行信干噪比(Signal to Interference plus Noise Ratio，SINR)；下行信噪比(Signal to Noise Ratio，SNR)；上行信干噪比；上行信噪比；下行路径损耗；上行路径损耗。
在本申请实施例中，第一测量值的阈值可以由基站配置或者采用默认值。阈值可以包括1个或2个取值。对于不同的取值，第一测量值的变化量超过阈值可以包括以下情况：
阈值包括1个取值，第一测量值的变化量满足以下之一：[-阈值，+阈值]、(-阈值，+阈值)、(-阈值，+阈值]或者[-阈值，+阈值)时，表示第一测量值的变化量没有超过阈值，TA处于有效状态。否则，表示第一测量值的变化量超过阈值，TA处于无效状态。
阈值包括2个取值，分别为阈值1和阈值2，第一测量值的变化量满足以下之一：[阈值1，阈值2]；(阈值1，阈值2)；(阈值1，阈值2]；[阈值1，阈值2)时，表示第一测量值的变化量没有超过阈值，TA处于有效状态。否则，表示第一测量值的变化量超过阈值，TA处于无效状态。
上述示例中，[]表示的是封闭区间，区间的边界分别为“-阈值”和“+阈值”；()表示的是开区间，区间的边界分别为“-阈值”和“+阈值”。
方式二：终端基于定时器(Timer)判断TA有效性。该方式中，如果判断时刻判断满足以下条件之一，终端的TA处于无效状态。否则，TA处于有效状态。
(1)在第二判断时刻集合中至少M1个判断时刻判断定时器超时；其中，M1为大于或等于1的整数。例如，如果M1等于1，则在第二判断时刻集合中 至少一个判断时刻判断定时器超时，表示TA处于无效状态。
(2)在第二判断时刻集合中最后M2个判断时刻判断定时器超时；其中，M2为大于或等于1的整数。例如，如果M2等于1，则在第二判断时刻集合中最后一个判断时刻判断定时器超时，表示TA处于无效状态。其中，第二判断时刻集合中最后一个判断时刻可以为第二判断时刻集合中距离下一个第一类信道资源的时域位置最近的判断时刻。
(3)在第二判断时刻集合中前M3个判断时刻判断定时器超时；其中，M3为大于或等于1的整数。例如，如果M3等于1，则在第二判断时刻集合中第一个判断时刻判断定时器超时，表示TA处于无效状态。其中，第二判断时刻集合中第一个判断时刻可以为第二判断时刻集合中距离下一个第一类信道资源的时域位置最远的判断时刻。
在本申请实施例中，定时器超时的情况可以包括，在下一个第一类信道的时刻定时器超时。所述第二判断时刻集合可以由基站配置并且发送给终端，或者采用默认配置。
在一种示例中，所述第二判断时刻集合中的判断时刻满足以下至少一个：
距离下一个第一类信道使用的资源的时域位置的间隔大于或者等于第一时长T1；
距离下一个第一类信道使用的资源的时域位置的间隔小于或者等于第二时长T2。
在本示例中，T1、T2的取值可以由基站配置或者采用默认取值。
T1的作用可以包括：如果判断为TA处于无效状态，在T1这个时间段内可以保证完成终端的TA从无效状态转变到TA有效状态的整个过程。这样，终端还可以继续使用下一个第一类信道的资源来发送上行数据。
T2的作用可以包括：如果判断时刻过早，并且假设在此次判断中TA被判断为无效状态，终端需要放弃使用下一个第一类信道的资源来发送上行数据；或者终端在下一个第一类信道的资源之前进行TA更新操作，将TA从无效状态转变到TA有效状态。但由于判断时刻过早，基站可能在这个判断时刻之后对终端的TA进行更新，使得定时器重置。那么，在下一个第一类信道资源时刻定时器可能不会超时。因此，通过配置T2可以保证判断时刻不会太早。
方式三：终端基于某些参数的测量值以及定时器判断TA有效性。该方式中，如果判断时刻判断满足以下条件之一，终端的TA处于无效状态。否则，TA处于有效状态。
(1)在第二判断时刻集合中的判断时刻判断定时器没有超时，且在所述判断时刻之前至少有K1次第一测量值的变化量超过阈值；其中，K1为大于或等于1的整数。例如，如果K1等于1，在第二判断时刻集合中的任意一个判断时刻判断定时器没有超时，且在该判断时刻之前至少有一次第一测量值的变化量超过阈值，表示TA处于无效状态。
(2)在第二判断时刻集合中的判断时刻判断定时器没有超时，且在所述判断时刻之前的最后K2次的第一测量值的变化量超过阈值；其中，K2为大于或等于1的整数。例如，如果K2等于1，在第二判断时刻集合中的任意一个判断时刻判断定时器没有超时，且在该判断时刻之前的最后一次第一测量值的变化量超过阈值，表示TA处于无效状态。
在一个应用示例中，在一个无线通信系统中，基站(eNB)发送上行传输配置信息给终端(User Equipment，UE)，其中，该上行信道配置信息包括：上行信道资源的配置信息以及下行控制信道搜索空间的配置信息。
基站通过上行信道资源的配置信息为终端配置了第一类信道资源，其中，所述第一类信道资源是为支持终端在RRC空闲状态下进行上行传输而配置的。通过下行控制信道搜索空间的配置信息配置的下行控制信道则是与所述第一类信道资源对应的。所述下行控制信道中至少承载了所述第一类信道对应的HARQ-ACK信息。
本实施例中，第一类信道占用的资源在时域上周期分布。第一类信道占用的资源可以称为“预配置上行资源(Preconfigured Uplink Resource，PUR)”，使用所述第一类信道的上行传输称为PUR传输。
本实施例中，所述PUR传输是在RRC空闲状态下进行的。终端在PUR传输之前，需要判断当前TA是否处于有效状态，只有当TA处于有效状态时，终端才可以进行PUR传输。
如果终端的服务小区(serving cell)或者终端的驻留小区(camping cell)没有发生改变时，当满足特定条件时，TA处于无效状态。其中，所述特定条件包括：
在至少一个判断时刻判断参考信号接收功率(RSRP)的变化量超过阈值。其中，所述判断时刻包含在第一判断时刻集合中。
其中，D_RSRP＝RSRP1-RSRP0。其中，D_RSRP为RSRP的变化量；RSRP1为当前时刻测量得到的RSRP值或者当前时刻保存的RSRP测量值；RSRP0为最近一次TA值更新时保存的RSRP测量值；
其中，所述判断时刻在PUR传输之前，判断时刻的数量大于或等于0。
本实施例中，基站通过信令配置D_RSRP的变化范围为[阈值1，阈值2]，则当D_RSRP在[阈值1，阈值2]内时，表示D_RSRP没有超过阈值，因此，TA处于有效状态。否则，表示D_RSRP超过阈值，因此，TA处于无效状态。
本申请另一实施例提供一种传输控制方法，在上述实施例的步骤S12中，发起随机接入过程(Random Access Procedure，RAP)可以包括多种方式。
在一种实施方式中，发起随机接入过程，可以包括：
向基站发送随机接入过程的第三消息Msg3，所述第三消息承载的RRC消息中携带用于表示RRC释放的指示信息。
在一种实施方式中，发起随机接入过程，还可以包括：
接收来自基站的随机接入过程的第四消息Msg4，所述第四消息中包括RRC连接释放(RRC Connection Release)消息。
在本申请实施例中，所述RRC消息可以包括以下至少一种：
RRC连接恢复请求(RRC Connection Resume Request)；
RRC连接请求(RRC Connection Request)；
新定义的RRC消息。
在本申请实施例中，所述用于表示RRC释放的指示信息可以包括以下至少一种：
RRC连接释放指示；
TA获取指示，该指示可以隐含指示触发RRC连接释放；
一个或多个信元(Information Element，IE)，并且所述IE配置成预定义取值。
在一个应用示例中，在一个无线通信系统中，基站(eNB)发送上行传输配置信息给终端(UE)，其中，该上行信道配置信息包括：上行信道资源的配置信息以及下行控制信道搜索空间的配置信息。
基站通过上行信道资源的配置信息为终端配置了第一类信道资源，其中，所述第一类信道资源是为支持终端在RRC空闲状态下进行上行传输而配置的。通过下行控制信道搜索空间的配置信息配置的下行控制信道则是与所述第一类 信道资源对应的。所述下行控制信道中至少承载了所述第一类信道对应的HARQ-ACK信息。
本实施例中，第一类信道占用的资源在时域上周期分布。
终端在第一类信道上进行上行传输之前，需要判断当前TA是否处于有效状态。当TA处于有效状态时，终端可以用所述第一类信道进行上行传输。
当终端判断TA处于无效状态时，终端发起随机接入过程。如图3a所示，随机接入流程可以包括Msg1、Msg2、Msg3、Msg4这4个消息的传递。其中，UE向eNB发送的Msg1中承载前导(Preamble)，eNB向UE返回的Msg2中承载终端需要的TA信息。
终端通过随机接入过程中的Msg3中承载的RRC消息携带用于表示RRC释放的指示信息。基站在接收到终端发送的Msg3消息后，可以发送Msg4消息给终端，其中Msg4中承载RRC Connection Release消息。
终端通过所述随机接入过程完成TA的获取，然后结束随机接入过程。这样，终端可以在RRC空闲状态继续用第一类信道进行上行传输。
其中，Msg3中承载的RRC消息至少包括以下之一：
RRC连接恢复请求；
RRC连接请求。
其中，用于表示RRC释放的指示信息至少包括以下之一：
显式的RRC连接释放指示；
通过显式的TA获取指示信息隐含指示触发RRC连接释放。
通过Msg3中承载的RRC消息中的一个IE隐含指示RRC连接释放。例如IE为建立原因(establishmentCause)，并且将establishmentCause配置的取值的含义设为TA获取。此时，establishmentCause隐含指示RRC连接释放。
本申请实施例中，可以采用多种方式判断TA的有效性，在TA无效的情况下，可以发起随机接入过程，并在该随机接入过程中通过Msg3或Msg4释放RRC连接，保持RRC空闲状态或非激活状态。这样，在RRC空闲状态或非激活状态下，如果UE有需要传输的数据，可以在第一类信道进行数据传输。在TA有效状态下，不需要从RRC空闲状态进入RRC连接状态，即可进行数据传输。因此利于终端继续在RRC空闲状态上使用所述第一类信道传输数据，可以减少终端的功耗，节约系统资源。
在一种实施方式中，发起随机接入过程，可以包括：
向基站发送随机接入过程的第三消息Msg3，所述第三消息承载终端识别信息，其中，所述终端识别信息通过媒体接入控制(Media Access Control，MAC)的控制单元(Control Element，CE)，即MAC CE发送。
其中，所述终端识别信息包括以下之一：

随机接入过程的第二消息Msg2中承载的临时(Temporary)C-RNTI；

在一个应用示例中，在一个无线通信系统中，基站(eNB)发送上行传输配置信息给终端(UE)，其中，该上行信道配置信息包括：上行信道资源的配置信息以及下行控制信道搜索空间的配置信息。
基站通过上行信道资源的配置信息为终端配置了第一类信道资源，其中，所述第一类信道资源是为支持终端在RRC空闲状态下进行上行传输而配置的。通过下行控制信道搜索空间的配置信息配置的下行控制信道则是与所述第一类信道资源对应的。所述下行控制信道中至少承载了所述第一类信道对应的HARQ-ACK信息。
第一类信道占用的资源在时域上周期分布。终端在第一类信道上进行上行传输之前，需要判断当前TA是否处于有效状态。当TA处于有效状态时，终端可以用所述第一类信道进行上行传输。
当终端判断TA处于无效状态时，终端发起随机接入过程。如图3b所示，随机接入流程可以包括Msg1、Msg2、Msg3这3个消息的传递。其中，UE向eNB发送的Msg1中承载前导(Preamble)，eNB向UE返回的Msg2中承载终端需要的TA信息。
终端通过随机接入过程完成TA的获取，然后结束随机接入过程，并且在RRC空闲状态继续用第一类信道进行上行传输。
其中，Msg3承载终端识别信息。终端识别信息可以通过C-RNTI MAC CE携带的C-RNTI来表示。C-RNTI可以包括以下之一：
C-RNTI；
Msg2中承载的Temporary C-RNTI；
为终端在RRC空闲状态用第一类信道进行上行传输配置的RNTI。
图4为本申请另一实施例的传输控制方法的流程示意图。如图4所示，该传输控制方法可以应用于终端中。在上述实施例的基础上，该方法还可以包括：
步骤S41、接收基站发送的针对第一类信道传输数据的HARQ-ACK信息，所述HARQ-ACK信息承载在下行控制信道中的下行控制信息中；
所述HARQ-ACK信息包括第一种ACK指示信息或第二种ACK指示信息。
其中，当所述ACK的指示信息为第一种ACK指示信息时，该HARQ-ACK信息表示所述第一类信道传输的数据正确接收，且所述终端停止检测下行控制信道。这种情况下，终端等到下一个第一类信道，然后继续进行数据传输。
当所述ACK的指示信息为第二种ACK指示信息时，该HARQ-ACK信息表示所述第一类信道传输的数据正确接收，且所述终端检测下行控制信道。在这个下行控制信道中可以承载下行信道调度信息或者上行信道的调度信息。终端接收到所述调度信息后，可以在相应的信道上进行数据传输或者接收。
本申请实施例中，基站可以通过不同的ACK指示终端默认找到对应的操作，无需再通过其他信令指示UE的具体操作方法。
图5为本申请另一实施例的传输控制方法的流程示意图。如图5所示，该传输控制方法可以应用于终端中。在上述实施例的基础上，该方法还可以包括：
步骤S51、接收基站发送的针对第一类信道的调整信息，所述调整信息承载在下行控制信道中的下行控制信息中，其中，调整信息的取值是根据第一类信道对应的功率余量(Power Headroom,PHR)确定的。其中，所述功率余量可以指终端发送第一类信道传输数据时剩余的功率，所述功率余量可以通过第一类信道传输给基站。

本实施例可以应用于基站侧，对于不同类型的终端，基站可以发送不同类型的信息来调整第一类信道的配置信息，使得第一类信道的配置信息更适合终端，从而使得不同类型的终端可以在RRC空闲状态或非激活状态在第一类信道发送数据。

随机接入信道上发送的随机接入信号。
在本实施例中，一种第一类随机接入信道的资源对应一个覆盖增强等级、一种随机接入信道的重复发送次数或者一种随机接入信号格式。
在一种实施方式中，所述终端在所述第一类随机接入信道上发送随机接入信号后，在一个时间窗内没有检测到所述基站发送的响应消息，所述终端在所述第二类随机接入信道上发送随机接入信号。
在本实施例中，寻呼消息可以在下行控制信道中发送。承载寻呼消息的DCI通过P-RNTI(Paging RNTI，寻呼无线网络临时标识)进行循环冗余校验(Cyclic Redundancy Check，CRC)加扰。
在一种实施方式中，终端的行为可以包括以下示例：

在该示例中，所述特定条件包括以下至少之一：
所述终端的覆盖增强等级小于或者等于所述第一类随机接入信道对应的覆盖增强等级；
