Definitions

  • the present invention relates to the field of communications, and in particular to a method and apparatus for data transmission.
  • LTE Long Term Evolution
  • some companies have proposed "proposed to study the problem of LTE deployed in unlicensed carriers.” For example, Qualcomm in the United States believes that with the rapid growth of data services, in the near future, authorized carriers will not be able to withstand the huge amount of data brought by rapid business growth.
  • the data volume pressure brought by the service growth can be solved.
  • the unlicensed carrier has the following characteristics: on the one hand, since the unlicensed carrier does not need to be purchased, or the carrier resource is zero cost, the unlicensed carrier is free or low-cost; on the other hand, since the individual and the enterprise can participate in the deployment, the device The quotient equipment is also available, so the admission requirements of the unlicensed carrier are low; in addition, the unlicensed carrier is shared, and some sharing can be considered when multiple different systems are operating at the same time or when different operators of the same system operate. The way resources are used to improve carrier efficiency.
  • LTE deployment has obvious advantages in unlicensed carriers, there are still problems in the process of deployment; among them, there are many wireless access technologies (cross-communication standards, difficult collaboration, and diverse network topologies) ) and many wireless access sites (large number of users, difficult collaboration, centralized management overhead). Due to the large number of wireless access technologies, there will be various wireless systems in the unlicensed carrier, which are difficult to coordinate with each other and have serious interference. Therefore, for LTE deployed in unlicensed carriers, there is still a need to support the regulation of unlicensed carriers. Most countries require the system to support the listening and speaking mechanism when deployed in unlicensed carriers. By listening to the mechanism first, it is possible to avoid interference caused by the simultaneous use of unlicensed carriers between adjacent systems.
  • the competition back-off mechanism is further introduced, that is, the neighboring system sites (generally the neighboring transmission nodes of the same system) can avoid the interference caused by the neighboring transmission nodes of the same system simultaneously using the unlicensed carriers through the contention back-off mechanism.
  • the regulation stipulates that devices that use unlicensed carriers (including base stations and user equipments (UEs)) need to perform a listening mechanism before the transmission, that is, Clear Channel Assessment (CCA).
  • CCA Clear Channel Assessment
  • the device can use the unlicensed carrier channel for data transmission.
  • data transmission by the UE is scheduled by the base station.
  • the base station sends uplink control signaling to the UE in the physical downlink control channel (Physical Downlink Control Channel, PDCCH for short) or the DCI of the enhanced physical downlink control channel ePDCCH, and the control signaling notifies the UE in the subframe n+
  • the resources in the 4 (such as physical resource blocks) use a given coded modulation scheme to transmit data to the base station.
  • the uplink subframe in which the UE transmits data and the subframe in which the base station sends the uplink control signaling maintain a predetermined subframe interval. For example, under Frequency Division Duplexing (FDD), the base station is in the subframe n.
  • FDD Frequency Division Duplexing
  • the uplink control signaling is sent, and then the UE sends the uplink data in the subframe n+4 (the duration of each subframe is 1 ms).
  • the interval is also in advance through a table. It is agreed that after the UE receives the uplink control signaling, it can pass the The fixed table knows that the uplink data should be sent in the first few subframes.
  • FIG. 1 is a schematic diagram of scheduling of an LTE FDD system in the related art.
  • a base station sends uplink grant signaling to a UE in a subframe K
  • the UE receives the signaling, and learns that the subframe is based on K+4.
  • the uplink authorization signaling sends the corresponding data, but before the arrival of the subframe K+4, the UE needs to perform the CCA detection first, and when the channel is detected to be idle (the energy in the detection channel is lower than the preset threshold), the UE uses the subframe.
  • K+4 transmits data. When it is detected that the channel is not idle (busy), the UE cannot transmit data using subframe K+4.
  • the UE will not be able to send uplink data in a subframe agreed with the base station in advance, which will cause the scheduled transmission to fail.
  • the base station sends uplink grant signaling failure, and wastes resources.
  • the embodiment of the present invention provides a method and an apparatus for data transmission, so as to at least solve the problem that the uplink data transmission fails in the uplink data transmission in the related art due to the CCA detection failure or the maximum single use duration limited in the regulation is too small.

Description

数据传输的方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种数据传输的方法及装置。
背景技术
目前，长期演进技术(Long Term Evolution，简称为LTE)的通信网络都是部署在授权载波中运营的，随着LTE的发展，一些公司提出了“建议研究LTE部署在非授权载波中的课题”，例如美国的高通公司认为：随着数据业务的快速增长，在不久的将来，授权载波将不能承受快速业务增长带来的巨大的数据量。考虑通过在非授权载波中部署LTE，以此来分担授权载波中的数据流量，可以解决业务增长带来的数据量压力。同时，非授权载波具有以下特点：一方面，由于非授权载波不需要购买，或者载波资源为零成本，因此非授权载波免费或低费用；另一方面，由于个人、企业都可以参与部署，设备商的设备也可以，因此非授权载波的准入要求低；再者，非授权载波具有共享性，通过多个不同系统都运营其中时或者同一系统的不同运营商运营其中时，可以考虑一些共享资源的方式，以提高载波效率。
综上所述，虽然LTE部署在非授权载波中具有明显的优势，但是，在部署的过程中，依然存在问题；其中，无线接入技术多(跨不同的通信标准，协作难，网络拓扑多样)和无线接入站点多(用户数量大，协作难度大，集中式管理开销大)。由于无线接入技术多，非授权载波中将存在各种各样的无线系统，彼此之间难于协调，干扰严重。因此，针对LTE部署在非授权载波中，仍然需要支持非授权载波的管制，多数国家要求系统在非授权载波中部署时，需要支持先听后说机制。通过先听后说机制可以避免相邻系统之间同时使用非授权载波而为彼此带来的干扰。并且进一步引入竞争回退机制，即邻近的系统站点(一般是同一系统的邻近传输节点)，通过竞争回退机制后可以避免相同系统的邻近传输节点同时使用非授权载波时带来的干扰。
并且，管制中规定，使用非授权载波的设备(包括基站和用户设备(UE))在发送之前都是需要进行先听后说机制，即空闲信道评估(Clear Channel Assessment，简称为CCA)，当信道空闲时，设备才能使用非授权载波信道进行数据发送。
在LTE系统中，UE的数据发送都是受到基站调度。例如，基站在子帧n的物理下行控制信道(Physical Downlink Control Channel，简称为PDCCH)或增强物理下行控制信道ePDCCH的DCI中发送上行控制信令给UE，控制信令通知UE在子帧n+4中那些资源(例如物理资源块)中采用给定的编码调制方式来发送数据给基站。在LTE中，UE发送数据的上行子帧与基站发送上行控制信令的子帧保持约定的子帧间隔，例如，频分双工(Frequency Division Duplexing，简称为FDD)下，基站在子帧n中发送上行控制信令，然后UE在子帧n+4中发送上行数据(每个子帧时长1ms)，对于时分双工(Time Division Duplexing，简称为TDD)下，上述间隔也是通过表格的方式事先约定的，即UE接收到上行控制信令后，就可以通过约 定的表格获知应该在第几个子帧中发送上行数据。
图1是相关技术中LTE FDD系统调度示意图，如图1所示，当基站在子帧K中发送上行授权信令给UE，UE接收到该信令，并获知在子帧K+4中根据上行授权信令发送对应的数据，但是当子帧K+4到达之前，UE需要先执行CCA检测，当检测到信道空闲(检测信道中能量低于预设门限)时，UE才会使用子帧K+4发送数据，当检测为信道非空闲(忙)时，UE就不能使用子帧K+4发送数据。显然，当后者发生时，UE将不能在与基站事先约定的子帧中发送上行数据，必将引起本次调度传输失败。同时，也造成基站发送上行授权信令失效，且浪费了资源。
针对相关技术中的上行数据发送由于CCA检测失败或管制中限制的最大单次使用时长过小导致上行数据发送失败的问题，目前尚未存在有效的解决方案。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。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组合。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
在本实施例中提供了一种数据传输的方法，图2是根据本发明实施例的数据传输的方法的流程图一，如图2所示，该流程包括如下步骤：
步骤S202，网络侧配置上行子帧位置信息和/或时间间隔信息，其中，上行子帧位置信息用于指示发送与上行授权信息对应的上行数据的候选上行子帧，时间间隔信息用于指示发送上行授权信息与发送上行数据之间的时间间隔；
步骤S204，网络侧向用户设备UE发送上行子帧位置信息和/或时间间隔信息；
步骤S206，网络侧接收UE在对应于上行子帧位置信息和/或时间间隔信息的子帧上发送的上行数据。
通过本实施例的上述步骤S202至S206，网络侧将配置好的上行子帧位置信息和/或时间间隔信息发送到UE，而该上行子帧位置信息用于指示发送与上行授权信息对应的上行数据的候选上行子帧，与该时间间隔信息用于指示发送上行授权信息与发送上行数据之间的时间间隔，即网络侧事先配置了用于发送上行数据的上行子帧或时间间隔，即使CCA检测失败UE也可以获得非授权载波，从而解决了相关技术中的上行数据发送由于CCA检测失败或管制中限制的最大单次使用时长过小导致上行数据发送失败的问题。
对于本实施例中步骤S202中涉及到的网络侧配置上行子帧位置信息和/或时间间隔信息，在本实施例的可选实施方式中，网络侧通过以下至少之一的方式配置上行子帧位置信息和/或 时间间隔信息：
方式一：网络侧通过用户设备UE专用RRC消息或系统广播RRC消息为UE配置上行子帧位置信息和/或时间间隔信息；
对于该方式一，在本实施例的具体实施方式中可以是：网络侧在UE专用RRC消息中添加上行子帧位置信息和/或时间间隔信息；或，网络侧系统广播RRC消息的指定系统信息块中添加上行子帧位置信息和/或时间间隔信息；进而通过UE专用RRC消息或系统广播RRC消息将行子帧位置信息和/或时间间隔信息发送到UE；
例如，在UE专用RRC消息中增加上述的时间间隔信息，当UE被配置(非)授权载波时，网络侧可以通过为UE配置(非)授权载波的专用RRC消息通知(非)授权载波中上行授权信息与对应的上行数据发送的时间间隔信息。UE在配置的(非)授权载波中，总是根据使用上述的RRC消息中的时间间隔为上行数据发送。
方式二：网络侧通过物理层信令配置上行子帧位置信息和/或时间间隔信息；
其中，对于该方式二在本实施例的可选实施方式中可以是，网络侧通过使用物理下行控制信道PDCCH中的下行控制信息DCI中的比特配置上行子帧位置信息和/或时间间隔信息。
需要说明的是，该方式二中的物理层包括：UE级别的物理层和公共的物理层，也就是说，网络侧采用UE级别的物理层的信令动态配置每次上行授权信息对应的时间间隔信息；网络侧采用公共的物理层的信令动态配置每次上行授权信息对应的时间间隔信息；
以UE级别的物理层为例，使用UE专用的(E)物理下行控制信道PDCCH中的下行控制信息DCI中的比特来表示，具体的包括，使用传输上行授权信息的PDCCH中的DCI中的比特来表示，即在该DCI中使用部分比特来指示该上行授权信息与对应的上行数据之间的时间间隔。UE在接收到上行授权信息后，并根据上行授权信息中的时间间隔信息确定上行数据发送的时刻或子帧。
方式三：网络侧通过高层信令和物理层信令结合的方式配置上行子帧位置信息和/或时间间隔信息；
其中，对于该方式三，在本实施例的可选实施方式中可以是，网络侧通过高层信令配置时间间隔集合和/或上行子帧集合；网络侧通过物理层信令从时间间隔集合和/或上行子帧集合中指示当前与上行授权信息对应的上行数据的时间间隔信息和/或上行子帧位置信息。
而在本实施例的另一个可选实施方式中可以是，网络侧通过高层信令配置上行子帧位置信息，并通过物理层信令配置时间间隔信息；或者，网络侧通过高层信令配置时间间隔信息，并通过物理层信令配置上行子帧位置信息。
需要说明的是，在网络侧同时通过高层信令和物理层信令配置时间间隔信息和/或上行子帧信息时，网络侧与UE约定UE接收到时间间隔信息和/或上行子帧信息以物理层信令通知为准。
例如，网络侧通过高层信令(RRC消息，包括广播类型的和UE专用RRC消息)配置上行授权信息与对应的上行数据发送的时间间隔信息。网络侧可以通过物理层信令再次配置时间间隔信息，此时配置的间隔信息不同于高层信令指示的，并且网络侧和接收端约定当发现高层和物理层通知的时间间隔信息(或不相同时)时，网络侧和接收端应该以物理层通知的时间间隔为当前(或当次)上行授权信息与对应的上行数据的时间间隔。之后仍然以高层通知的时间间隔为准。
方式四：网络侧动态修改与UE事先约定的上行子帧位置信息和/或时间间隔信息。
其中，在具体实施例中可以是，网络侧和UE约定使用常用的时间间隔(时间间隔信息不被发送)，然后网络侧根据调度需求，动态的修改当次(或非授权载波抢占后的本次突发数据传输)中的上行授权信息与对应的上行数据的时间间隔。之后仍然沿用约定的时间间隔。这种方式很适合某一时间间隔经常被使用，而其他间隔不经常使用的情况。例如约定使用时间间隔为4个子帧，当基站需要使用时间间隔为2个子帧时，基站就通过物理层信令(例如前述的物理层方式发送)通知UE。UE接收到后，认为此次上行授权信息和对应的上行数据发送时间间隔为2个子帧
方式五：网络侧按照小区或载波为单位配置统一的上行子帧位置信息和/或时间间隔信息。
其中，网络侧通过指定载波转发网络侧下其他载波或小区中的上行子帧位置信息和/或时间间隔信息。
另外，在本实施例的可选实施方式中，对于上述方式一至方式五中，在上行子帧位置信息和/或时间间隔信息由物理下行控制信道承载时，本实施例的方法还可以包括：
网络侧通过下行控制信息DCI配置上行子帧位置信息和/或时间间隔信息；或，网络侧与UE重新约定下行控制信息DCI中的下行分配指数DAI的比特，其中，该比特用于指示在非授权载波中作为上行子帧位置信息和/或时间间隔信息；或，网络侧与UE重新约定下行控制信息DCI中的上行指示UL index的比特，其中，该比特用于指示在非授权载波中作为上行子帧位置信息和/或时间间隔信息。
也就是说，在网络侧同时配置时间间隔信息和上行子帧位置信息，且时间间隔信息和上行子帧位置信息均为2种时，网络侧配置使用下行控制信息DCI中下行分配指数DAI中的第1个比特指示时间间隔，第2个比特指示上行子帧位置信息；或，网络侧配置使用下行控制信息DCI中上行指示UL index中的第1个比特指示时间间隔位置信息，第2个比特指示上行子帧位置信息。
图3是根据本发明实施例的数据传输的方法的流程图二，如图3所示，该方法的步骤包括：
步骤S302：用户设备UE接收网络侧配置并发送的上行子帧位置信息和/或时间间隔信息，其中，上行子帧位置信息用于指示发送与上行授权信息对应的上行数据的候选上行子帧，时间间隔信息用于指示发送上行授权信息与发送上行数据之间的时间间隔；
其中，在本实施例中UE可以通过高层信令和/或物理层信令接收上行子帧位置信息和/或时间间隔信息
步骤S304：UE在对应于上行子帧位置信息和/或时间间隔信息的子帧上向网络侧发送的上行数据。
需要说明的是，在UE同时收到高层信令和物理层信令配置的上行子帧位置信息和/或时间间隔信息时，UE以与网络侧事先的约定接收上行子帧位置信息和/或时间间隔信息为准，其中，约定指示以物理层信令配置的上行子帧位置信息和/或时间间隔信息为准。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明各个实施例所述的方法。
在本实施例中还提供了一种数据传输的装置，该装置应用于网络侧或UE侧，该装置用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。
图4是根据本发明实施例的数据传输的装置的结构框图一，该装置应用于网络侧，如图4所示，该装置包括：配置模块42，设置为配置上行子帧位置信息和/或时间间隔信息，其中，上行子帧位置信息用于指示发送与上行授权信息对应的上行数据的候选上行子帧，时间间隔信息用于指示发送上行授权信息与发送上行数据之间的时间间隔；第一发送模块44，与配置模块42耦合连接，设置为向用户设备UE发送上行子帧位置信息和/或时间间隔信息；第一接收模块46，与第一接收模块46耦合连接，设置为接收UE在对应于上行子帧位置信息和/或时间间隔信息的子帧上发送的上行数据。
可选地，本实施例中的配置模块42包括以下至少之一：第一配置单元，设置为通过用户设备UE专用RRC消息或系统广播RRC消息为UE配置上行子帧位置信息和/或时间间隔信息；第二配置单元，设置为通过物理层信令配置上行子帧位置信息和/或时间间隔信息；第三配置单元，设置为通过高层信令和物理层信令结合的方式配置上行子帧位置信息和/或时间间隔信息；第四配置单元，设置为动态修改与UE事先约定的上行子帧位置信息和/或时间间隔信息；第五配置单元，设置为按照小区或载波为单位配置统一的上行子帧位置信息和/或时间间隔信息。
其中，第一配置单元在具体的应用场景中可以是，设置为在UE专用RRC消息中添加上行子帧位置信息和/或时间间隔信息；或，在系统广播RRC消息的指定系统信息块中添加上行子帧位置信息和/或时间间隔信息。
第三配置单元在具体的应用场景中可以是，设置为通过高层信令配置时间间隔集合和/或上行子帧集合；进而通过物理层信令从时间间隔集合和/或上行子帧集合中指示当前与上行授权信息对应的上行数据的时间间隔信息和/或上行子帧位置信息。还可以是，设置为通过高层信令配置上行子帧位置信息，并通过物理层信令配置时间间隔信息；或者，设置为通过高层信令配置时间间隔信息，并通过物理层信令配置上行子帧位置信息。
需要说明的是，在网络侧同时通过高层信令和物理层信令配置时间间隔信息和/或上行子帧信息时，网络侧与UE约定UE接收到时间间隔信息和/或上行子帧信息以物理层信令通知为准。
可选地，第二配置单元在具体的应用场景中，还设置为侧通过使用物理下行控制信道PDCCH中的下行控制信息DCI中的比特配置上行子帧位置信息和/或时间间隔信息。
可选地，第五配置单元在具体的应用场景中，网络侧通过指定载波转发网络侧下其他载波或小区中的上行子帧位置信息和/或时间间隔信息。
在本实施例的另一个可选实施方式中，在上行子帧位置信息和/或时间间隔信息由物理下行控制信道承载时，本实施例还包括：第一配置模块，设置为通过下行控制信息DCI配置上行子帧位置信息和/或时间间隔信息；或，第二配置模块，设置为与UE重新约定下行控制信息DCI中的下行分配指数DAI的比特，其中，该比特用于指示在非授权载波中作为上行子帧位置信息和/或时间间隔信息；或，第三配置模块，设置为与UE重新约定下行控制信息DCI中的上行指示UL index的比特，其中，该比特用于指示在非授权载波中作为上行子帧位置信息和/或时间间隔信息。
可选地，第二配置模块，还设置为在网络侧同时配置时间间隔信息和上行子帧位置信息，且时间间隔信息和上行子帧位置信息均为2种时，网络侧配置使用下行控制信息DCI中下行分配指数DAI中的第1个比特指示时间间隔，第2个比特指示上行子帧位置信息；或，第三配置模块，还设置为配置使用下行控制信息DCI中上行指示UL index中的第1个比特指示时间间隔位置信息，第2个比特指示上行子帧位置信息。
图5是根据本发明可选实施例的数据传输的装置的结构框图二，该装置应用于用户设备UE侧，如图5所示，该装置包括：第二接收模块52，设置为接收网络侧配置并发送的上行子帧位置信息和/或时间间隔信息，其中，上行子帧位置信息用于指示发送与上行授权信息对应的上行数据的候选上行子帧，时间间隔信息用于指示发送上行授权信息与发送上行数据之间的时间间隔；第二发送模块54，与第二接收模块52耦合连接，设置为在对应于上行子帧位置信息和/或时间间隔信息的子帧上向网络侧发送的上行数据。
需要说明的是，上述各个模块是可以通过软件或硬件来实现的，对于后者，可以通过以下方式实现，但不限于此：上述模块均位于同一处理器中；或者，上述模块分别位于多个处理器中。
下面结合本发明的可选实施例对本发明进行举例说明；
随着接收端(例如UE)和网络侧(例如基站)硬件处理水平的提升，原本在LTE系统中定义的上行授权信息与对应的上行数据传输的时间间隔也是可能由4个子帧(4ms，FDD系统为例)变为2个子帧(仅仅是一个举例)，此时对于新的UE，可以按照新的新的时间间隔来工作，也可能在某些时候需要按照就的时间间隔来工作。
因此，本可选实施例提供了一种控制信令增强以及对应的使用方法，下面通过两个实施例对本可选实施例进行说明；
可选实施例一
网络侧(例如基站)配置上述的时间间隔，并将配置信息发送给接收端(UE)；接收端接收上述的时间间隔配置信息，并应用时间间隔配置信息，确定接收的上行授权信息对应的上行数据发送的时间位置，在对应的时间位置发送上行数据；网络侧然后根据配置的时间间隔，在对应的上行子帧中接收对应的上行数据。
需要说明的是，本可选实施例中涉及到的时间间隔信息是上行授权信息发送的时刻(或子帧)与对应的上行数据发送的时刻(或子帧)之间的时间间隔(或子帧数)，例如，在时间间隔按照时间长度描述时可以是2ms，4ms或1ms等；而按照间隔的子帧数量描述可以是2个子帧，4个子帧等。
下面结合本可选实施例的可选实施方式来介绍时间间隔信息的发送，以及对应的接收端行为流程的方法：
可选实施方式1，网络侧采用UE级别的物理层的信令动态配置每次上行授权信息对应的时间间隔信息。
其中，使用UE专用的物理下行控制信道(Physical Downlink Control Channel，简称为DCCH)或(Enhanced Physical Downlink Control Channel，简称为EPDCCH)中的下行控制信息(Downlink Control Information，简称为DCI)中的比特来表示，在具体的应用场景中可以是：使用传输上行授权信息的PDCCH中的DCI中的比特来表示，即在该DCI中使用部分比特来指示该上行授权信息与对应的上行数据之间的时间间隔。UE在接收到上行授权信息后，并根据上行授权信息中的时间间隔信息确定上行数据发送的时刻或子帧。
可选实施方式2，网络侧采用公共的物理层的信令动态配置每次上行授权信息对应的时间间隔信息。
其中，使用DCI 1C通过(E)PDCCH公共检索区域来发送时间间隔信息，此时时间间隔信息对于小区内的所有UE都是有效的，且该时间间隔信息可以在基站抢占的每个下行子帧都发送。接收端在接收到上行授权信息后，再结合公共DCI中配置的时间间隔信息来确定上行数据发送的时刻或子帧。
可选实施方式3，网络侧采用专用RRC消息发送上述时间间隔信息。
起哄，在UE专用RRC消息中增加上述的时间间隔信息，当UE被配置(非)授权载波 时，基站可以通过为UE配置(非)授权载波的专用RRC消息通知(非)授权载波中上行授权信息与对应的上行数据发送的时间间隔信息。UE在配置的(非)授权载波中，总是根据使用上述的RRC消息中的时间间隔为上行数据发送。
可选实施方式4，网络侧采用广播类型的RRC消息发送上述时间间隔信息。
其中，在系统信息块1中增加上述时间间隔以及对应的载波信息，(当信息以载波为单位配置发送时，则载波信息是已有的被包含在系统信息块1中的，只需要增加时间间隔信息即可，默认应用于系统信息块1对应的载波)。当基站为UE配置(非)授权载波时，通过UE专用RRC消息转发被配置的(非)授权载波系统信息块1时，UE就可以获知被配置的(非)授权载波中的上述时间间隔信息。UE在配置的(非)授权载波中，总是根据使用上述的广播类型的RRC消息中的时间间隔为上行数据发送。对于主分量载波的情况，UE可以通过接收该载波中的系统信息块1来获取该载波中的时间间隔信息。
可选实施方式5，网络侧采用高层信令和物理层信令结合的方式来通知或调整或使用上述时间间隔。
其中，网络侧通过高层信令(RRC消息，包括广播类型的和UE专用RRC消息)配置上行授权信息与对应的上行数据发送的时间间隔信息。网络侧可以通过物理层信令再次配置时间间隔信息，此时配置的间隔信息不同于高层信令指示的，并且网络侧和接收端约定当发现高层和物理层通知的时间间隔信息(或不相同时)时，网络侧和接收端应该以物理层通知的时间间隔为当前(或当次)上行授权信息与对应的上行数据的时间间隔。之后仍然以高层通知的时间间隔为准。
通过该方式既可以克服高层信令半静态改变的不灵活性，也不会带来物理层信令开销显著增加。
可选实施方式6，网络侧和接收端约定某一个时间间隔，然后网络侧再通过物理层信令(或高层信令)动态修改时间间隔。
其中，网络侧和接收端约定使用常用的时间间隔(时间间隔信息不被发送)，然后网络侧根据调度需求，动态的修改当次(或非授权载波抢占后的本次突发数据传输)中的上行授权信息与对应的上行数据的时间间隔。之后仍然沿用约定的时间间隔。这种方式很适合某一时间间隔经常被使用，而其他间隔不经常使用的情况。例如约定使用时间间隔为4个子帧，当基站需要使用时间间隔为2个子帧时，基站就通过物理层信令(例如前述的物理层方式发送)通知UE。UE接收到后，认为此次上行授权信息和对应的上行数据发送时间间隔为2个子帧。
需要说明的是，上述的可选实施方式在使用(E)PDCCH承载所述时间间隔信息时，本可选实施例的具体信令设计如下：
方案1，重新定义，并使用(E)PDCCH中的DCI中的UL index的比特来描述时间间隔信息。当系统中存在2个候选的时间间隔时，例如分别为2和4，那么就是用UL index的比特的第一个比特描述(此时第二个比特预留)。当UE配置使用在非授权载波或者授权载波(但 是此时该授权载波不使用TDD上下行子帧配置0)时，UE认为原有的UL index比特信息是用来描述所述时间间隔信息的。
方案2，重新定义，并使用(E)PDCCH中的DCI中的DAI的比特来描述时间间隔信息。当系统中存在2个候选的时间间隔时，例如分别为2和4，那么就是用DAI的比特的第一个比特描述(此时第二个比特预留)。
方案3，站点使用DCI 1C中的比特来描述所述时间间隔信息，在子帧的PDCCH公共搜索空间进行发送，且固定使用前4个或8个CCE。例如，在描述下行最后一个子帧占用的符号的DCI信息中，增加描述所述时间间隔的信息。包含了所述时间间隔的信息的DCI可以在每个下行子帧发送，或者在下行最后2个子帧中发送。
上述的时间间隔信息也可以使用PHICH信道进行承载发送。由于相关技术中在非授权载波，不再使用PHICH信道，所以在可选本实施例中，当在非授权载波中需要通过物理层信令来配置时间间隔信息时，PHICH能被使用。例如，使用PHICH的资源，采用PDCCH的DCI编码映射规则；或者直接使用PHICH资源和PHICH的编码映射规则。
网络侧和UE侧也可以根据业务的等级(例如业务QoS)约定对应的业务传输时的时间间隔。例如，对于传输的业务，网络侧和接收端都是知道对应的QoS等级的，例如，某一或某些QoS等级业务对应时间间隔为2，一些对应的时间间隔为4，那么当对应的业务被调度传输时，网络侧和接收端都默认使用约定的时间间隔进行接收和发送。
UE接收到或通过约定方式获得了时间间隔信息后，UE然后按照DCI中的相关控制信息(例如资源分配、MCS等)在对应的子帧中发送上行数据。
可选实施例二：
基站(网络侧)与UE预定约定上行授权信息对应的上行数据发送的候选上行子帧位置。UE在接收上行授权信息后，UE根据约定，确认候选上行子帧位置。
在非授权载波时，当UE在接收到上行授权信息之后，UE在所述候选的上行子帧之前执行CCA检测，当CCA检测为信道空闲时，UE则使用剩余的候选上行子帧发送数据。
网络侧和UE侧约定，每次上行授权信息发送之后，按照给定时间间隔(例如，LTE在不考虑引入新的时间间隔时，间隔为4个子帧)，向后约定存在2个或3或4个候选的上行子帧用来发送所述上行授权信息对应的上行数据。例如，网络侧和UE侧约定，候选上行子帧数量为2个(约定的候选上行子帧数量越多，网络侧的检测复杂度越高)，此时，基站在子帧K中发送了上行授权信息给UE，UE在子帧K中接收到上行授权信息，然后UE就可以获知，本次上行授权信息对应的数据候选上行子帧为K+4和K+5。K+4是LTE系统正常的时间间隔，由于约定有2个候选上行子帧，所以向后顺延一个上行子帧，即K+5。采用约定的方式，可以不需要发送信令给UE，从而节约信令开销。
当然，候选的上行子帧数，也可以通过高层信令，例如UE专用RRC消息或广播类型的 RRC消息可以半静态的配置和改变候选上行子帧数。例如，如果设置不同UE具有不同的候选上行子帧数量，那么基站可以采用UE专用的RRC消息为不同的UE，根据UE的需求、能力配置对应的候选上行子帧数量，也可以包括候选上行子帧的起始子帧(也适合上面的一段的描述，上一段实际默认候选上行子帧的起始子帧为K+4，即系统支持的默认间隔)。例如当系统中支持不同的默认间隔，例如授权载波之间的默认间隔为4，非授权载波的默认间隔为2，或者可以配置为2时，基站可以根据UE的能力(是否支持新的默认间隔2)来配置UE候选上行子帧的起始子帧。
基站也可以通过广播类型的RRC消息来配置小区级别的，或载波级别的候选上行子帧数量和/或起始子帧。这样小区的所有UE或正在使用所述载波的UE，都按照广播消息中配置的候选上行子帧来进行上行数据的发送。
显然，候选上行子帧数量，如果作为一个参数，前述的发送时间间隔参数的所有方式都可以用来发送该参数，且使用方式也是相同，UE侧和基站侧的行为根据候选上行子帧的功能和作用，略作修改即可。
例如，候选上行子帧数量也可以通过物理层的DCI、PHICH等来传输，或者物理层和高层结合的方式，或者高层半静态配置，物理层动态当次生效的方式。高层配置候选上行子帧数量和/或时间间隔，然后通过物理层信令即时修改当次上行授权信息对应的候选上行子帧数量和/或时间间隔，UE如果接收到物理层的信令，则按照物理层信令处理当次的候选上行子帧数量和/或时间间隔，否则按照高层信令配置的处理。
也可以采用，高层信令配置可能的候选上行子帧数量，例如配置候选上行子帧数量为{1，2，3，4}，或{1，2}或{1,3}等，总之高层信令配置候选上行子帧数量的集合。然后，物理层信令具体指示当次上行授权信息具体对应的候选上行子帧数量，例如高层配置为{1,2}，物理层信令指示当次候选上行子帧数量为1或2。这种方式也可以用于时间间隔的指示。
图6是本发明可选实施例的时间间隔和候选上行子帧的示意图，如图6所示，通过时间间隔和候选上行子帧数描述了上行授权信息对应的上行数据发送的上行子帧集合。UE在集合中的上行子帧之前或中间执行CCA成功后，就可以选择其中一个或多个子帧来进行所述上行数据发送。一般的，基站先确定时间间隔，再确定候选上行子帧数量，需要说明的是，图6中的候选上行子帧是以时间间隔为2示意的，而在其他的可选实施方式中也可以约定时间间隔，或候选上行子帧数，通知另一个，也可以两个参数都通知。通知的方式可以采用本可选实施例的上述方式。
本可选实施例还提供了另一种可选实施方式，当基站按照现有的一个上行授权信息对应的上行数据发送的上行子帧为一个时，如果UE执行CCA失败后，下一次基站为UE配置候选的上行子帧集合。
在本可选实施方式中，候选的上行子帧数量的信令设计可以是：
方案1，重新定义，并使用现有的(E)PDCCH中的DCI中的UL index的比特来描述。 设计候选上行子帧数量为1个固定值时，例如固定2个上行子帧，且固定起始子帧为上行授权信息的子帧+4来确定。这种情况下，直接使用DCI中的UL index中的一个比特来触发是否为UE配置了候选上行子帧数为2，或者没有候选上行子帧(即现有机制的中的只有一个上行子帧)。设计候选上行子帧的起始子帧为2(即时间间隔有2个)，候选上行子帧数量为2个可能值时，例如为2个上行子帧，或1个上行子帧(1个上行子帧即为现有方式)时，则信令设计为，使用DCI中UL index中的一个比特指示起始子帧或时间间隔，然后另一个比特描述候选上行子帧数量为2个还是1个。
方案2，重新定义，并使用现有的(E)PDCCH中的DCI中的DAI的比特来描述。具体设计上与上述的UL index是相同的，这里不再赘述。
方案3，基站使用DCI 1C中的比特来描述所述时间间隔信息，在子帧的PDCCH公共搜索空间进行发送，且固定使用前4个或8个CCE。例如，在描述下行最后一个子帧占用的符号的DCI信息中，增加描述所述时间间隔的信息和/或候选上行子帧数量，其中，包含了所述时间间隔的信息的DCI可以在每个下行子帧发送，或者在下行最后2个子帧中发送。
由于候选上行子帧数量超过1个，就意味基站侧需要盲检UE最终是在哪一个上行子帧中发送了上行数据，那么显然增加了基站的复杂度。下面增加一个补充方式以降低基站检测的复杂度。
基站与UE约定数据起始符号位置，或者基站配置数据的起始符号位置，这样就会使得UE侧发送上行数据的起始符号固定下来，避免由于UE执行CCA检测导致可能太多的数据起始符号，导致基站盲检数据失败。
需要说明的是上述方式之间可以组合使用也可以单独使用。
上述方式也可以被用于UE发送ACK/NACK时的子帧(集合)指示。本申请不再针对ACK/NACK的发送赘述。
为了更好的支持不同的时间间隔的UE工作，提供下面的方式：
UE上报自己支持的时间间隔能力信息给基站，基站能够根据UE的不同时间间隔的能力配置UE的上行子帧数据发送的时间间隔。
当UE在下面2种情况之一上报自己支持的时间间隔能力信息：
1.UE在接入网络时
2.UE接收到基站为其配置非授权载波时
上报时，采用UE专用RRC消息将所述时间间隔信息发送给基站。
为UE配置多个候选上行子帧是为了提升UE执行CCA检测成功的概率，依据同样的思路，针对下面多个单独的连续调度的上行子帧，建议UE侧执行CCA的方式为：
当基站在连续多个下行子帧中发送上行授权信息调度UE时，例如，基站在子帧n、n+1、 n+2上发送针对子帧n+4、n+5、n+6的上行授权信息时，那么UE在某一子帧之前执行CCA成功并发送数据后，在剩余的子帧中直接发送数据，例如，UE在子帧n+4之前执行CCA成功，并在子帧n+4中发送数据后，UE在子帧n+5、n+6中不执行CCA，直接发送数据。或者UE在子帧n+5(n+4之前CCA失败)之前执行CCA成功，并在子帧n+4中发送数据后，UE在子帧n+6中不执行CCA，直接发送数据。
这样，可以减少UE执行CCA的次数，从而提升上行调度的成功率。
下面提供一种通知UE，基站抢占非授权载波占用的子帧信息。
当基站为UE配置非授权载波时，并且通过跨载波的方式调度UE在非授权载波中进行上行数据发送时，基站应该将计划在非授权载波中占用子帧(即UE发送上行数据的子帧)的数量通知给UE，此时基站通过主载波的PDCCH公共搜索空间来通知，例如使用DCI 1C来通知。例如通知非授权载波中那些子帧将是上行子帧。具体信令可以为：基站在主载波中发送非授权载波中的上行授权信息的子帧作为起点，时间间隔之后连续多少个UL子帧。预定描述非授权载波中计划占用的上行子帧起点为：主载波中发送非授权载波中上行授权信息的子帧+时间间隔后对应的子帧；计划占用的上行子帧数：从上述起点开始连续计划占用的子帧数量。
时间间隔可以事先约定，例如约定为4个子帧。
下面提供一种UL数据发送之前CCA的执行位置和UL数据起始位置的设计。这种设计可以有效解决下行最后一个子帧为部分子帧时，UL数据的起始位置设计以及对应的UL CCA位置设计(下面描述未声明的部分都按照LTE系统的说明执行)。
目前LTE系统部署在非授权载波的系统规定，在一次突发传输中，基站占用的连续下行子帧中，最后一个子帧可以占用该子帧的前3、6、9、10、11、12或14个符号，针对前面6种情况，此时最后一个下行子帧为部分子帧，存在未被使用的OFDM符号。之后的子帧为UL子帧。
针对这种情况，基站和UE约定采用下面的方式来进行数据发送和UL CCA位置设计。
UE上行数据(PUSCH/PUCCH)的起始位置允许从符号0或符号7开始。UE上行数据起始符号的前一个符号作为UL CCA执行的位置。尤其是在下面的情况：
当子帧n为下行最后一个子帧，且占用的符号为前3、6个时，UE的上行数据允许从该子帧的符号7开始传输。UE在子帧n的符号6中执行CCA检测，当发现信道空闲，UE允许在符号7开始发送数据。当基站配置最后一个下行子帧n为部分子帧，且占用前3、6个符号时，基站在子帧n-4中发送上行授权信息，此时被调度的UE在子帧n中的符号6中执行CCA检测，如果CCA检测发现信道空闲，则在符号7开始发送上行数据。基站也在子帧n的符号7开始接收持续7个符号的上行数据。
当子帧n为下行最后一个子帧，且占用的符号为前9、10、11、12个时，UE的上行数据允许从子帧n+1的符号0开始传输。UE在子帧n符号13和/或14中执行CCA检测，当发现 信道空闲，UE允许在符号0开始发送数据。当基站配置最后一个下行子帧n为部分子帧，且占用前9、10、11、12个符号时，基站在子帧n-3中发送上行授权信息，此时被调度的UE在子帧n中的符号13和/或14中执行CCA检测，如果CCA检测发现信道空闲，则在子帧n+1的符号0开始发送上行数据。基站也在子帧n+1的符号0开始接收持续14个符号的上行数据。
当子帧n为下行最后一个子帧，且占用的符号为前14个时，UE的上行数据允许从子帧n+1的符号0开始传输。UE在子帧n的符号14中执行CCA检测，当发现信道空闲，UE允许在符号0开始发送数据。当基站配置最后一个下行子帧n为完整子帧时，基站在子帧n-3中发送上行授权信息，此时被调度的UE在子帧n中的符号14中执行CCA检测，如果CCA检测发现信道空闲，则在子帧n+1的符号0开始发送上行数据。基站也在子帧n+1的符号0开始接收持续14个符号的上行数据。此时UE在子帧n中的符号14中执行的CCA检测为CCA图样检测(即在约定的RE中执行CCA检测)。
本发明的实施例还提供了一种存储介质。可选地，在本实施例中，上述存储介质可以被设置为存储用于执行以下步骤的程序代码：

工业实用性
在本发明实施例数据传输过程中，网络侧将配置好的上行子帧位置信息和/或时间间隔信息发送到UE，而该上行子帧位置信息用于指示发送与上行授权信息对应的上行数据的候选上行子帧，与该时间间隔信息用于指示发送上行授权信息与发送上行数据之间的时间间隔，即网络侧事先配置了用于发送上行数据的上行子帧或时间间隔，即使CCA检测失败UE也可以获得非授权载波，从而解决了相关技术中的上行数据发送由于CCA检测失败或管制中限制的最大单次使用时长过小导致上行数据发送失败的问题。
