  • the present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for uplink information processing.
  • the Long Term Evolution (LTE) system uses Orthogonal Frequency Division Multiplexing (OFDM) technology.
  • the uplink resource allocation of the LTE system is based on the Transmission Time Interval (TTI).
  • TTI Transmission Time Interval
  • the length of one TTI is 14 OFDM symbols, that is, one subframe, and the length of one TTI is 1 ms.
  • the base station indicates the uplink shared channel of the user equipment (English: User Equipment, UE) in the corresponding uplink subframe by using the uplink grant (English: UL grant) included in the downlink control channel.

  • the frequency domain resources occupied by the scheduled PUSCH are indicated by the resource allocation (English: Resource Allocation, RA) information carried in the UL grant.
  • each PUSCH of the conventional LTE can only be scheduled by one UL grant with a fixed timing relationship, when the uplink service demand is greater than the downlink service requirement, the base station only needs to carry a small amount of downlink data, but needs to configure a large number of downlink subframes to pass.

Therefore, how to support efficient uplink transmission on unlicensed spectrum when the uplink and downlink services are unbalanced is an urgent problem to be solved.

Description

一种上行信息处理的方法及装置 技术领域
本发明涉及通信技术领域，尤其涉及一种上行信息处理的方法及装置。
背景技术
长期演进(英文：Long Term Evolution，LTE)系统采用正交频分复用(英文：Orthogonal Frequency Division Multiplexing，OFDM)技术。LTE系统的上行资源分配以传输时间间隔(Transmission Time Interval，TTI)为粒度，1个TTI的长度为14OFDM符号，即1个子帧，一个TTI的长度为1ms。在LTE系统的上行传输中，基站通过在下行控制信道中包含的上行授权(英文：UL grant)指示用户设备(英文：User Equipment，UE)在对应的上行子帧上的上行共享信道(英文：Physical Uplink Shared Channel，PUSCH)上发送的数据信息。UL grant与其调度的PUSCH之间具有固定的时序关系，第n个子帧(记为子帧#n)的下行控制信道中包含的UL grant调度的PUSCH位于第(n+4)个子帧(记为子帧#n+4)。被调度的PUSCH所占的频域资源由UL grant中携带的资源分配(英文：Resource Allocation，RA)信息指示。
由于传统LTE的每个PUSCH只能由具有固定时序关系的一个UL grant调度，当上行业务需求大于下行业务需求时，基站只需要承载少量的下行数据，但是却需要配置大量的下行子帧以通过UL grant调度足够的PUSCH资源，造成时域资源的浪费，并需要频繁地执行先听后发(英文：Listen-Before-Talk，LBT)信道接入机制。LBT失败会导致UL grant无法发送，进而上行PUSCH也无法被调度，导致信道接入机会受限。再者，由于UL grant固定的时序关系的约束，基站无法调度到更远的上行子帧。因此，如何在上下行业务不均衡的时候支持非授权频谱上高效率的上行传输是亟待解决的问题。
现有技术中，增强授权辅助接入(英文：enhanced Licensed-Assisted Access，eLAA)中引入多子帧调度。基站设备可以在一个下行子帧中发送多个UL grant，以及在一个ULgrant中调度多个连续的上行子帧，可以减少频繁发送UL grant对信道资源的浪费，并且UL grant的定时是灵活的，能够支持调度到更远的UL子帧。然而，在现有技术中，由于UL grant的最小调度时延是4ms(该时延用于UE接收检测UL grant以及在被UL grant指示的上行资源上发送的PUSCH进行组包)，因此当下行突发小于4个子帧时，下行突发与被调度的上行突发之间仍然存在空闲时间(Gap)，UE无法使用该空闲时间进行上行传输，无法高效利用信道资源。

具体实施方式
在LTE系统采用的OFDM技术中，用于数据传输的最小资源单位是资源粒子(英文：Resource Element，RE)，一个RE对应时域上的1个OFDM符号和频域上的1个子载波。在此基础上，资源块(英文：Resource Block，RB)由多个时域上连续的OFDM符号和频域上连续的子载波组成，RB是资源调度的基本单位。LTE系统的上行传输采用单载波，1个RE对应1个单载波频分多址接入(英文：Single Carrier Frequency Division Multiplexing Access，SC-FDMA)符号和频域上的1个子载波。在LTE系统的上行传输中，UL grant是UE特定的控制信令，UL grant与其调度的PUSCH之间具有固定的时序关系，子帧#n的下行控制信道中包含的UL grant调度的PUSCH位于子帧#n+4。
为了扩展可使用带宽，Release 13引入授权辅助接入的长期演进(英文：Licensed-Assisted Access using Long Term Evolution，LAA-LTE)技术，通过载波聚合(英文：Carrier Aggregation，CA)技术，可以将可用的频谱扩展到非授权频段，利用授权频谱实现无缝覆盖以及承载部分时延要求高的业务，非授权频谱承载部分数据业务。为了实现在非授权频谱上满足和不同运营商的基站、UE，以及Wi-Fi等异系统无线节点的友好共存，LAA系统采用LBT信道接入机制，基站在侦听到信道空闲后再发送下行信息。具体的，下行传输的LBT为基于随机回退的空闲信道评测(英文：Clear Channel Assessment，CCA)(Type 1UL channel access)。具体流程是：发送节点在0～竞争窗长度(英文：Contention Window Size，CWS)之间均匀随机生成一个回退计数器N，并且以侦听时隙(英文：CCA slot)为粒度进行侦听。如果侦听时隙内检测到信道空闲，则将回退计数器减一，反之检测到信道忙碌，则将回退计数器挂起，即回退计数器N在信道忙碌时间内保持不变，直到检测到信道空闲。当回退计数器减为0时发送节点可以立即占用该信道。发送节点在占用信道后，可以连续发送信息的最大时间长度为最大信道占用时间(英文：Maximum Channel Occupancy Time，MCOT)，持续占用信道达到该长度后需要释放信道，重新执行LBT后才能再次接入。信道状态的判断准则为：无线通信设备将侦听时隙内的接收到信道上的功率与能量检测门限比较，如果高于门限，则为信道忙碌，如果低于门限，则为信道空闲。
在Release 14引入的eLAA中进一步地支持非授权频谱的上行传输。与现有LTE系统一致，eLAA上行传输由基站发送UL grant调度完成，终端设备在被调度的上行传输之前也需要通过LBT确认信道空闲才能发送。另外，上行传输支持两种LBT类型：基于随机回退的CCA以及单时隙CCA。其中，基于随机回退的CCA与下行传输类似。单时隙CCA流程是：发送节点执行一个长度为25us的单时隙的CCA侦听，如果25us的CCA时隙检测到信道空闲，则发送节点可以立即接入信道。如果25us的CCA时隙内检测到信道忙碌，发送节点放弃发送 信息，并且可以等待下一个上行数据信道之前再执行下一次的单时隙CCA侦听。为了提高上行接入信道的机会，可以将基站抢占信道后占用的MCOT共享给终端设备使用，终端设备在MCOT以内可以执行单时隙CCA，超出MCOT则需要执行随机回退CCA。具体的，基站通过下行控制信道中包含的小区特定的控制信令(英文：Common PDCCH，CPDCCH)将上行突发的起始时刻和持续时长通知给终端设备。终端设备在上行突发以内的上行传输可以执行单时隙CCA接入信道，而超出上行突发的上行传输需要执行随机回退CCA接入信道。另外，CPDCCH还用于通知下行尾子帧的符号数目、触发两级上行调度等。其中一个下行突发的最后一个下行子帧称为尾子帧，基站在下行尾子帧中可能不占满子帧的全部符号，而是只占用子帧靠前的符号，而不占用靠后的符号发送下行信息，靠后的符号保留空闲以便于给下一个子帧的上行传输执行LBT，或者靠后的符号用于UE发送上行控制信道，承载随机接入信息、上行探测参考信号、下行混合自动重传请求(英文：Hybrid Automatic Repeat reQuest，HARQ)ACK反馈(即HARQ-ACK反馈)等。例如，下行突发的最后一个子帧(尾子帧)包含14个符号，而基站在该尾子帧占用前K个符号发送下行信息，其中K可为3、6、9、10、11、12、14中的一个值。
由于传统LTE的每个PUSCH只能由具有固定时序关系的一个UL grant调度，当上行业务需求大于下行业务需求时，基站只需要承载少量的下行数据，但是却需要配置大量的下行子帧以通过UL grant调度足够的PUSCH资源，造成时域资源的浪费，并需要频繁地执行LBT，导致信道接入机会受限。参见图1，图1为资源调度的上行/下行子帧的一位置关系示意图。如图1，当基站需要调度4个上行子帧时，需要配置4个下行子帧并在每个下行子帧中发送1个UL grant，而这些下行子帧不能用于上行传输。其中，每个下行子帧中发送的UL grant用于调度该下行子帧对应的上行子帧，例如下行子帧#n中发送的UL grant用于调度上行子帧#n+4。其次，当下行子帧中不需要发送下行PDSCH时，相邻的两个承载UL grant的PDCCH之间没有PDSCH信息时，基站可能需要停止占用信道，因此信道占用是不连续的，基站在发送后一个UL grant之前仍然需要执行LBT，LBT失败会导致UL grant无法发送，进而上行PUSCH也无法被调度。再者，由于UL grant与UL grant调度的PUSCH之间具有固定时序的定时关系，例如子帧#n中的UL grant只能调度子帧#n+4上的PUSCH基站无法调度到更远的上行子帧。
由此可见，如何在上下行业务不均衡的时候支持非授权频谱上高效率的上行传输是亟待解决的问题。为此本发明实施例提供了一种上行信息处理的方法及装置，可通过基站设备发送的下行控制信息指示终端设备可用的时域资源为下行传输结束之后的时域资源。终端设备可以在下行控制信息指示的时域资源上发送上行数据而不需要基站设备提前发送UL grant调度。终端设备可以根据预配置好的上行数据信道格式提前对在PUSCH上要发送的数据信息进行组包，在检测到该下行控制信息后立即在对应上述时域资源上发送上行数据信息，并且不需要在此之前发送调度请求(英文：Scheduling Request，SR)并等待UL grant，减小了上行传输的时延，提高了上行传输效率。
需要说明的是，本发明实施例可以应用于工作在非授权频谱上的无线通信系统，也可以应用于工作在授权频谱上的无线通信系统。其中，上述无线通信系统的基站设备在授权频谱或非授权频谱上发送下行信息(或称下行数据信息)，上述无线通信系统的终端设备 在授权频谱或非授权频谱上发送上行信息(或称上行数据信息)。授权频谱和非授权频谱上基于UL grant调度的上行传输的调度时延都是4ms，因此采用本发明实施例在调度时延带来的空闲时间内，在免调度许可(英文：Grant Free，或Grant-less)的PUSCH上发送数据信息都可以享受时延减小以及上行传输效率提升带来的好处。另外，对于非授权频谱上的上行传输，本发明实施例提供的实现方式免除了终端设备发送SR以及等待UL grant的操作，可额外避免了SR以及UL grant抢占不到信道带来的接入机会的损失，适用性高。
本发明实施例提供的实现方式中涉及的网元主要是可以工作在授权频谱或非授权频谱上的基站设备和终端设备(或称UE)。其中，上述基站设备包括宏基站、微小区、微微小区、家庭基站、远端射频头以及中继等，具体可根据实际应用场景确定，在此不做限制。上述终端设备可包括手机、能接入LTE系统的笔记本电脑、平板电脑等，具体可根据实际应用场景确定，在此不做限制。下面将结合图2至图12，对本发明实施例提供的上行信息处理的方法及装置进行描述。
参见图2，是本发明实施例提供的上行信息处理的方法流程示意图。本发明实施例提供的方法，包括步骤：
S101，基站设备在第一下行传输时间间隔上向终端设备发送第一控制信息。
S102，终端设备接收基站设备在第一下行传输时间间隔上发送的第一控制信息。
具体实现中，对于传统的UL grant调度的上行传输，基站设备需要在接收到终端设备发送的SR之后，通过UL grant调度终端设备发送上行数据信息。由于基站设备接收UE发送的SR和终端设备接收到基站发送的UL grant之间的时延，导致上行传输的时延较大。本发明实施例通过引入免调度许可机制，终端设备不需要向基站设备发送SR，也不需要接收基站设备发送的UL grant，而是直接在基站设备配置的上行PUSCH资源上发送上行数据信息，减小了时延，提高了资源利用率。
在一些可行的实施方式中，基站设备可在第一下行传输时间间隔(即第一下行TTI)上发送第一控制信息，其中，所述第一控制信息用于指示免调度许可的时域资源。具体实现中，基站设备可以将同一份免调度许可的时频资源分配给多个终端设备，并通过统计复用的方式避免终端设备没有上行数据发送导致资源浪费。同时基站设备可以通过控制配置在同一免调度许可资源上的终端设备数目，以避免终端设备过多导致多个终端设备同时在一份时域资源上发送数据信息，进而出现数据信息发送的碰撞问题。
在一些可行的实施方式中，免调度许可的时域资源和频域资源可通过基站设备发送的高层信令半静态配置。然而，考虑到下行业务到达的随机性，基站设备发送下行传输的时机以及下行传输的结束时刻(例如下行传输的最后一个子帧或者下行传输的最后一个TTI)是动态的。另外，下行传输之前需要执行LBT，使下行传输时机的动态特性更加明显，因此下行传输的结束时刻很有可能和预配置的免调度许可时域资源的起始时间单元相距较远，仍然不能有效利用DL-UL之间的空闲时间传输上行数据信息。基于此，本发明实施例在根据基站设备发送高层信令配置免调度许可的时域资源的实现方式之外，提出了动态指示时域资源的实现方式。本发明实施例可通过基站设备下发的第一控制信息显式或隐式地指示免调度许可的时域资源，包括时域资源的起始时间单元，和/或时域资源的长度，和/或时域资源的结束时刻等。当终端设备有上行数据传输需求时，可以提前根据预配置好的上行数 据信道格式提前对在PUSCH上要发送的数据信息进行组包，并在接收到基站设备发送的第一控制信息之后，根据第一控制信息确定免调度许可的时域资源，进而可在第一控制信息指示的时域资源上发送组包之后的上行数据。如图3，图3是资源调度的上行/下行子帧的另一位置关系示意图。如图3所示，基站设备在下行子帧#n上发送UL grant调度的最近的下行子帧(或下行TTI)为下行子帧#n+4。为了利用下行子帧#n+1至下行子帧#n+3的这3个下行子帧的时域资源，基站设备可以通过在下行子帧#n上发送第一控制信息，将下行子帧#n+1至下行子帧#n+3的这3个下行子帧指示为免调度许可的时域资源。终端设备接收到第一控制信息后，可根据第一控制信息确定可以利用这部分时域资源来发送上行数据信息，即终端设备可根据第一控制信息确定这部分时域资源为免调度许可的时域资源。
应理解，下行传输时间间隔(即下行TTI)是下行传输的最小时间传输单元，上行传输时间间隔(即上行TTI)是上行传输的最小时间传输单元。应理解，下行传输时间间隔中传输的数据信息中包含下行控制信息，该下行控制信息可以对包括在同一下行传输时间间隔内的下行数据信道进行下行资源调度，也可以对该下行传输时间间隔之后的上行传输时间间隔内的上行数据信道进行上行资源调度。Release 14之前的LTE系统都是采用长度为1ms的TTI，即上行TTI和下行TTI的长度都为1ms，也就是上行TTI和下行TTI的长度均为1个子帧的长度。Release 14和5G NR(英文：New Radio)中引入了更短的TTI长度，支持短TTI(英文：short TTI，sTTI)传输的基站设备和终端设备可以支持长度为1ms的TTI和长度短于1ms的上行sTTI/下行sTTI。其中，sTTI支持的可选长度包括7个SC-FDMA(英文：SC-FDMA Symbol，SS)符号，1个SS，2个SS、3个SS、4个SS等。也就是说一个下行子帧中可以包含至少两个下行sTTI，一个上行子帧中可以包含至少两个上行sTTI。本发明实施例中的下行TTI可以是长度为1ms的TTI，也就是一个子帧，也可以是长度短于1ms的sTTI，其中，长度短于1ms的sTTI至少包含一个下行OFDM符号。上行TTI可以是长度为1ms的TTI，也就是一个子帧，也可以是长度短于1ms的sTTI，其中，长度短于1ms的sTTI至少包含一个上行SC-FDMA符号。需要说明的是，在具体实现中，一个长度为1ms的TTI(即一个子帧)或一个长度短于1ms的sTTI都称之为一个TTI，具体可根据实际应用场景中基站设备或者终端设备所采用的TTI格式确定，在此不做限制。
在一些可行的实施方式中，基站设备发送的第一控制信息指示的时域资源即为本发明实施例中描述的免调度许可资源(或称免调度许可的时域资源)。本发明实施例中描述的免调度许可资源用于终端设备的免调度许可PUSCH传输。基站设备可以将一个时域资源和/或频域资源仅分配给一个终端设备作为免调度许可资源，也可以将同一时域资源和/或频域资源分配给至少两个终端设备作为免调度许可资源。对于免调度许可的时域资源，终端设备可以自己决定是否使用该时域资源发送上行数据信息，以及使用该时域资源中的哪些上行TTI发送上行数据信息。也就是说，当免调度许可的时域资源包括至少两个上行TTI时，终端设备接收到第一控制信息后，可以在该时域资源中的至少一个上行TTI上发送上行数据信息，可以占用该时域资源中的部分上行TTI，也可以占用全部的时域资源。该时域资源包含至少一个TTI或子帧，该至少一个TTI/子帧中的任意一个TTI/子帧可以是完整TTI/子帧，也可以是部分TTI/子帧，也就是说此时终端设备只能在该TTI/子帧的一部分时域资源上发送数据信息。上述时域资源位于承载第一控制信息的第一下行TTI之后，即该时域资源的第一 个TTI或者第一个子帧在承载第一控制信息的第一下行TTI之后。
在一些可行的实施方式中，上述时域资源的起始时间单元与该第一下行TTI(以下简称该下行TTI或者上述下行TTI)的结束时刻的时间间隔可以等于零，也就是说上述时域资源的起始时间单元紧跟着该下行TTI。上述时域资源的起始时间单元与该下行TTI的结束时刻之间的时间间隔也可以大于零，也就是说该下行TTI的结束时刻之后隔一段时间后该时域资源才开始。上述时域资源的起始时间单元与该下行TTI的结束时刻之间的时间间隔大于零时，该时间间隔可以用于LBT侦听。或者，在一些实现方式中，该下行TTI之后可能还有其他下行TTI要传输数据信息，即该下行TTI并不是下行突发的最后一个下行TTI。此时，上述时域资源要在该下行TTI之后的其他下行TTI所要传输的数据信息传输完成之后。或者，若该下行TTI包含在下行尾子帧中，基站设备在下行尾子帧没有占满全部的下行符号，此时，第一控制信息指示的免调度许可的时域资源在下行尾子帧结束之后。
在一些可行的实施方式中，基站设备发送的第一控制信息可以是用户特定的控制信息，也可以是用户组特定的控制信息，也可以是公共控制信息。其中，用户特定的控制信息采用用户特定的无线网络临时标识符(英文：Radio Network Temporary Identifier，RNTI)加扰，只能被该特定的终端设备检测到且该控制信息只针对该特定终端设备生效。用户组特定的控制信息只能被该特定的一组终端设备(至少两个终端设备)检测到且该控制信息只针对该组包含的终端设备生效。公共控制信息采用小区特定的RNTI加扰，可以被小区中包含的所有已激活的终端设备检测到且该公共控制信息针对所有检测得到该公共控制信息的终端设备生效。
在一些可行的实施方式中，当第一控制信息为公共控制信令(即公共控制信息)时，该第一控制信息用于指示免调度许可的时域资源，并且该第一控制信息可以利用现有的公共控制信道(英文：Common PDCCH，CPDCCH)。基站设备可采用小区公共的RNTI(英文：Cell Common-RNTI，CC-RNTI)对公共控制信令进行加扰。基站设备也可以采用新的公共控制信道格式，或者说采用新的小区特定RNTI加扰该公共控制信令。具体实现中，该公共控制信令可以承载在PDCCH信道区域。进一步的，考虑到LTE系统原有的物理混合自动重传指示信道(英文：Physical Hybrid ARQ Indicator Channel，PHICH)信道可能不需要被工作在非授权频谱或Release 14版本的终端设备接收用作HARQ指示，该闲置的PHICH信道对应的物理资源可以用于承载该公共控制信息用于向上述终端设备指示上述时域资源。
S103，终端设备根据所述第一控制信息确定时域资源。
在一些可行的实施方式中，终端设备接收到第一控制信息之后可根据第一控制信息确定用于免调度许可的时域资源，包括该时域资源的起始时间单元、时域资源的长度(即时长)、时域资源的结束时刻等时域资源参数。其中，终端设备确定上述三个时域资源参数中的任意两个参数则可以确定第三个参数，即终端设备确定了上述3个时域资源参数中的2个参数则可确定该时域资源。具体的，上述时域资源的起始时间单元在时间上晚于目标时间单元，上述目标时间单元与起始时间单元之间的时间间隔为第一时间间隔。
上述起始时间单元包括允许终端设备在该时域资源最早发送上行数据信息的传输时间间隔，即该时域资源包含的至少一个TTI中的第一个TTI(称为起始TTI)或该时域资源包含的至少一个子帧中的第一个子帧(称为起始子帧)，上述时域资源的起始时刻为允许终端设 备在该时域资源上发送数据信息的最早时刻。其中，起始时刻包括时域资源的起始子帧或起始TTI，和/或允许终端设备在起始子帧/起始TTI开始发送数据信息的位置(起始位置)。上述起始时间单元包括该时域资源的起始TTI或起始子帧，该起始TTI/起始子帧可以是完整的TTI或完整的子帧，也可以是部分TTI或部分子帧。其中，对于某些起始TTI/起始子帧，终端设备需要占用一个完整TTI/完整子帧的全部时域发送数据信息。对于另外一些起始TTI/起始子帧，终端设备并不需要占用一个完整TTI/完整子帧的全部时域，而只占用该完整TTI/完整子帧的一部分时域发送数据信息，允许终端设备在该完整TTI/完整子帧中占用的时域部分称为部分TTI/部分子帧。起始时间单元的起始边界为，终端设备在该起始TTI/起始子帧中开始发送数据信息的起始位置(英文：Start position)。具体的，当该起始TTI/起始子帧为完整TTI/子帧时，起始TTI/起始子帧的起始位置等于该TTI/子帧的起始边界，起始时间单元为该起始TTI/起始子帧。具体的，当该起始TTI/起始子帧为部分TTI/部分子帧时，起始TTI/起始子帧的起始位置在一个完整TTI/完整子帧的中间(或者说在起始TTI/起始子帧所在的完整TTI/完整子帧的起始边界和结束边界之间)，起始时间单元可以是该完整TTI/完整子帧，也可以是从该完整TTI/完整子帧的起始位置到该起始TTI/起始子帧的结束边界的部分。其中，起始位置为允许终端设备在起始TTI/起始子帧开始发送上行数据信息的时刻。对于授权频谱，起始TTI/起始子帧总是完整TTI/完整子帧，起始位置可以总在起始TTI/起始子帧的起始边界(例如，该完整子帧起始边界处，称为0us)。对于非授权频谱，可选的，起始TTI/起始子帧可以是完整TTI/完整子帧，起始位置可以在起始TTI/起始子帧的起始边界(0us)，这种情况下起始时间单元为时域资源包含的第一个完整TTI/完整子帧，如图4中的(a)所示。图4是本发明实施例提供的时域资源的一示意图。可选的，起始TTI/起始子帧也可以是部分TTI/部分子帧，起始位置也可以位于起始TTI/起始子帧所在的完整TTI/完整子帧的中间，具体的可以是第一个上行符号的中间或第二个上行符号起始处。例如，当时域资源紧跟在下行突发的尾子帧之后，且尾子帧占满14个符号时，起始位置可以位于完整TTI/完整子帧的第二个上行符号起始处，如图4中的(d)所示(称为1符号)。这种情况下，起始时间单元可以是时域资源包含的第一个完整TTI/完整子帧，也可以是该第一个完整TTI/完整子帧中从第二个符号起始处到子帧结束边界的部分(斜方格部分)。起始位置也可以位于完整TTI/完整子帧的起始边界之后25us处(称为25us)，在第一个符号的中间，如图4中的(b)所示。这种情况下，起始时间单元可以是时域资源包含的第一个完整TTI/完整子帧，也可以是该第一个完整TTI/完整子帧中从25us到子帧结束边界的部分(斜方格部分)。起始位置也可以位于完整TTI/完整子帧的起始边界之后25us+TA(英文：Timing Advance)处(称为25us+TA)，在第一个符号的中间，如图4中的(c)所示。这种情况下，起始时间单元可以是时域资源包含的第一个完整TTI/完整子帧，也可以是该第一个完整TTI/完整子帧中从25us+TA到子帧结束边界的部分(斜方格部分)。在起始子帧靠前的位置上预留1个符号，或25us，或(25us+TA)空闲间隔以便于上行数据信道执行LBT。
上述目标时间单元为承载第一控制信息的下行传输时间间隔(即第一下行TTI)；或者，上述目标时间单元为第一下行TTI所在的子帧；或者，上述目标时间单元为下行突发的最后一个子帧或最后一个TTI，上述下行突发包含上述目标下行TTI，上述下行突发为时间上连续的至少一个下行TTI。上述目标时间单元可以是完整TTI/子帧，也可以是部分TTI/子帧， 其中，当基站设备在一个完整TTI/完整子帧中不占用全部时域而只占用一部分时域发送下行信息，其占用的时域部分称为部分TTI/部分子帧。
上述第一时间间隔为目标时间单元与起始时间单元之间的时间间隔。可选的，第一时间间隔为目标时间单元所在的完整TTI/完整子帧的起始边界或结束边界与起始时间单元对应的起始位置之间的时间间隔。例如，目标时间单元为下行突发的最后一个子帧，即尾子帧。基站在尾子帧占用的时域范围为第一个符号(称为符号#1)～第三个符号(称为符号#3)，起始时间单元为尾子帧之后的第一个完整子帧，起始位置为子帧边界，则第一时间间隔为尾子帧的起始边界到起始时间单元对应的起始位置之间的时间间隔，即1个子帧。或者，第一时间间隔为尾子帧的结束边界到起始时间单元对应的起始位置之间的时间间隔，即0。
上述第一时间间隔为目标时间单元与起始时间单元之间的时间间隔，可选的，第一时间间隔为目标时间单元所在的完整TTI/完整子帧的起始边界或结束边界与起始时间单元所在的完整TTI/完整子帧的起始边界之间的时间间隔。例如，目标时间单元为下行突发的最后一个子帧即尾子帧，基站在尾子帧占用全部符号，起始时间单元为尾子帧之后的第一个子帧，起始位置为子帧的第二个符号的起始处(1符号)，则第一时间间隔为尾子帧的起始边界到起始时间单元对应的起始位置之间的时间间隔，即1个子帧+1符号；或者，第一时间间隔为尾子帧的结束边界到起始时间单元对应的起始位置之间的时间间隔，即1符号。
上述结束时刻包括允许终端设备在该时域资源上发送数据信息的最晚时刻，上述结束时刻包括时域资源包含的最后一个子帧或最后一个TTI(称为结束时间单元)，和/或允许终端设备在该最后一个子帧/最后一个TTI停止发送数据信息的位置(结束位置)。该最后一个子帧/最后一个TTI可以是完整子帧/完整TTI，也可以是部分子帧/部分TTI。该结束位置可以是该时域资源包含的最后一个子帧/最后一个TTI所在完整子帧/完整TTI的起始边界或结束边界，也可以在最后一个子帧/最后一个TTI所在完整子帧/完整TTI的中间。
上述时域资源的时长为起始时刻和结束时刻之间的时间长度。具体的，可以是该时域资源的起始时间单元或起始时间单元所在的完整TTI/完整子帧与结束时间单元(或结束时间单元所在的完整TTI/完整子帧)之间的时间长度，也可以是起始时间单元对应的起始位置与结束时间单元对应的结束位置之间的时间长度。本发明实施例针对终端设备如何获取该时域资源的时长和起始时刻进行说明，该方法同样适用于终端设备获取该时域资源的时长和结束时刻，或者获取该时域资源的起始时刻和结束时刻。
在一些可行的实施方式中，基站设备可以通过第一控制信息将免调度许可的时域资源的时长通知给终端设备，终端设备可根据第一控制信息直接确定时域资源的时长。需要说明的是，基站设备通过第一控制信息指示该时域资源的时长，可以体现为指示上行TTI的数目，也可以体现为指示上行子帧的数目，也可以体现为指示毫秒数。终端设备可根据第一控制信息的指示确定时域资源的时长，操作简单。具体实现中，当第一控制信息为CPDCCH时，基站设备可以通过在CPDCCH中引入新的比特域用以显式指示该时域资源的时长。应理解，该时域资源在时间上是连续的，其中，上述时间上连续包括连续的TTI或子帧。连续的TTI或者子帧可体现为相邻的两个TTI或子帧之间是连续的，或者相邻的两个TTI或者子帧之间有空闲间隔(例如一个符号或部分符号的空闲间隔)，该空闲间隔用于执行LBT。
类似的，基站设备也可以通过第一控制信息将免调度许可时域资源的结束时刻指示给 终端设备。这种基站设备通过第一控制信息指示免调度许可的时域资源的通知方式可以动态地通知终端设备免调度许可时域资源的时长，代价是增加了通知信令开销。例如，当上/下行TTI为长度为1ms的TTI(即1个子帧)，UL grant调度时延为4ms，基站在非授权频谱上发送的下行突发的长度为1个子帧时，DL-UL之间的空闲时间(下行突发结束的子帧到下行突发中包含的UL grant所调度到的最早的上行子帧之间的时间)为3ms。由于3ms之后基站设备可以通过UL grant调度上行数据信道，因此免调度许可的时域资源的时长可以指示为3ms。同理，基站设备在非授权频谱上发送的下行突发长度为2个子帧时，DL-UL之间的空闲时间则为2ms，免调度许可的时域资源的时长可以指示为2ms。
在一些可行的实施方式中，基站设备可以通过第一高层信令将免调度许可的时域资源的时长通知给终端设备。终端设备在接收第一控制信息之前接收第一高层信令，并通过第一高层信令配置该时域资源的时长。基站设备通过第一高层信令配置免调度许可的时域资源的时长，可节省信令开销。第一控制信息仅用于指示免调度许可的时域资源。具体的，对于非授权频谱，不需要额外地引入新的控制信令比特域，类似于上述实现方式，终端设备通过检测到第一控制信息的存在性触发上行数据信息的发送。具体地，当第一控制信息为CPDCCH时，由于CPDCCH会指示当前子帧或下一个子帧为尾子帧，终端设备检测到CPDCCH时，若起始时间单元为尾子帧之后紧跟的第一个子帧，可以确定尾子帧之后紧跟的x个子帧为免调度许可的时域资源，x为配置的时域资源的时长。这种通知方式同样适用于第一控制信息为用户特定控制信息或用户组特定的控制信息的场景。
可选的，本发明实施例提供的免调度许可的时域资源的时长可以是预定义的。例如，可预先定义免调度许可的时域资源的时长为2个子帧或2个TTI，或3个子帧或3个TTI等，具体可根据实际应用场景确定，在此不做限制。
可选的，终端设备确定上述时域资源的时长，可以直接确定上述时域资源的时长为上述第一高层信令配置的时长，或预定义的时长，或基站设备通过第一控制信息指示的时长。或者说确定上述时域资源的结束时刻由时域资源的起始时刻加上上述时域资源的时长得到。例如，当上述起始时刻为下行突发的尾子帧之后紧跟的第一个子帧，记为子帧#m+1，上述时长为x个子帧时，上述结束时刻为子帧#m+x，上述时域资源为尾子帧之后紧跟的x个子帧。也就是说，第一高层信令配置的时长，或预定义的时长，或基站设备通过第一控制信息指示的时长对应从起始时刻到结束时刻之间的时间长度，等于时域资源的实际时长。
可选的，终端设备确定上述时域资源的时长，可以确定上述时域资源的时长为上述第一高层信令配置的时长，或预定义的时长，或基站设备通过第一控制信息指示的时长减去第一时间间隔。或者说确定上述时域资源的结束时刻由目标时间单元的结束时刻(或者说目标时间单元后的第一个TTI)加上上述时域资源的时长得到。这种方式下，由于目标时间单元是固定的，终端设备确定的时域资源结束时刻与第一时间间隔无关，而只与时长有关，基站可以不需要动态指示第一时间间隔，而采用预定义或高层信令配置的方式，因此，这种方式也可以看成是确定时域资源的结束时刻的方式，其中该结束时刻由上述第一高层信令配置或预定义或由基站设备通过第一控制信息指示。例如，假设第一时间间隔为尾子帧的结束边界到起始时间单元对应的起始位置之间的时间间隔，当上述目标时间单元为下行突发的尾子帧，上述起始时刻为该尾子帧之后紧跟的第一个子帧，记为子帧#m+1。上述配 置或预定义或指示的时长为x个子帧时，第一时间间隔为0，上述结束时刻为子帧#m+x，上述时域资源为尾子帧之后紧跟的x个子帧。当上述起始时刻为该尾子帧之后紧跟的第二个子帧，记为子帧#m+2，上述配置或预定义或指示的时长为x个子帧时，第一时间间隔为1个子帧，上述结束时刻仍然为子帧#m+x，上述时域资源为从子帧#m+2开始的x-1个子帧。
在一些可行的实施方式中，基站设备可以通过第一控制信息触发终端设备发送或不发送免调度许可的上行数据信息。
可选的，该触发信息可以是第一控制信息中独立的比特位，也可以与用于指示免调度许可的时域资源的时长的信息联合编码，作为终端设备发送或者不发送免调度许可的上行数据信息的两种状态中的其中一种状态进行触发。上述第一控制信息作为独立比特位触发时，可以通过第一控制信息中包含的一个独立比特位进行触发。具体的，若独立比特位为“0”则代表未触发终端设备发送上行数据信息。若独立比特位为“1”则代表触发终端设备发送上行数据信息。具体的，触发终端设备在目标时间单元之后紧跟的x个子帧/TTI中的至少一个子帧/TTI上发送免调度许可的上行数据信息，或者，触发终端设备从起始时间单元开始的x个子帧/TTI中的至少一个子帧/TTI上发送免调度许可的上行数据信息。其中，上述x由第一控制信息指示，即由第一控制信息指示免调度许可的时域资源的长度，或者，上述x为预定义的或者由基站发送的第一高层信令配置。上述起始时间单元由目标时间单元加上第一时间间隔确定，上述第一时间间隔由第一控制信息指示，或者，第一时间间隔为预定义或者由基站发送的第二高层信令配置。
可选的，终端设备也可通过检测到第一控制信息的存在性进行触发。具体的，当第一控制信息为CPDCCH时，终端设备可以根据检测到的CPDCCH确定目标时间单元。具体的，根据检测到的CPDCCH确定当前子帧或下一个子帧为尾子帧。若起始时间单元为尾子帧之后紧跟的第一个子帧/TTI，终端设备检测到CPDCCH则可以在目标时间单元之后紧跟的x个子帧/TTI中的至少一个子帧/TTI上发送免调度许可的上行数据信息，或者，终端设备从起始时间单元开始的x个子帧/TTI中的至少一个子帧/TTI上发送免调度许可的上行数据信息。其中，上述x由第一控制信息指示，即由第一控制信息指示免调度许可的时域资源的长度。或者，上述x为预定义的或者由基站发送的第一高层信令配置。上述起始时间单元由目标时间单元加上第一时间间隔确定，上述第一时间间隔由第一控制信息指示，或者，第一时间间隔为预定义或者由基站发送的第二高层信令配置。
进一步的，触发信息可与用于指示免调度许可的时域资源的时长的信息联合编码。例如，第一控制信息可以包含2bit的比特域，2bit的比特域编码可得到4种状态，包括“00”、“01”、“10”、“11”。上述4种状态可以分别指示时域资源的时长为{0,1,2,3}，其中1、2和3分别对应时域资源的时长为1个、2个和3个上行TTI/上行子帧。当基站设备指示免调度许可的时域资源的时长等于0时，终端设备接收到上述第一控制信息之后可确认没有指示免调度许可的时域资源或没有触发终端设备发送免调度许可的数据信道，不发送免调度许可的上行数据信息。
需要说明的是，下行控制信息采用小区特定的RNTI(例如CC-RNTI)或用户特定的RNTI加扰，并且除了有效控制信息的比特域之外，还包含循环冗余校验(英文：Cyclic Redundancy Check,CRC)比特域。终端设备用小区特定RNTI或用户特定的RNTI对下行子帧或下行TTI 的控制信道区域进行盲检测并且对CRC比特域进行校验，如果CRC校验正确，则确定该下行控制信息存在，并且进一步地，该下行控制信息中包含针对自己的指示信息。这种通知方式同样适用于第一控制信息为用户特定控制信息或用户组特定的控制信息的场景，在此不再赘述。
在一些可行的实施方式中，终端设备接收到第一控制信息之后，可根据第一控制信息确定免调度许可的时域资源的起始时间单元。具体实现中，终端设备确定免调度许可的时域资源的起始时间单元可以通过以下四种方式：预定义起始时间单元，第二高层信令通知起始时间单元，第一控制信息显式通知起始时间单元，第一控制信息隐式通知起始时间单元等。
需要说明的是，终端设备确定免调度许可的时域资源的起始时间单元包括确定免调度许可的时域资源的起始子帧/起始TTI，也包括确定该起始子帧/起始TTI对应的起始位置。
需要说明的是，由于免调度许可的时域资源的起始时间单元是动态的，终端设备确定免调度许可的时域资源的起始时间单元可以根据目标时间单元，以及起始时间单元和一个目标时间单元之间的时间间隔，即第一时间间隔，或者说相比于目标时间单元的偏移(英文：Offset)确定。也就是说起始时间单元由目标时间单元加上第一时间间隔得到。其中，目标时间单元可以由终端设备根据检测到的第一控制信息确定，可以是某一个TTI(设为目标TTI)或者某一个子帧(设为目标子帧)。
终端设备可以根据第一控制信息确定目标时间单元，可选的，该目标时间单元可以由检测第一控制信息的存在性得到，具体的，目标TTI/目标子帧是承载第一控制信息的下行TTI或子帧(即第一下行TTI)，或者该下行TTI所在的子帧(如果该TTI为sTTI)，终端设备对第一控制信息进行监测(英文：Monitor)或者说盲检测(英文：Blind Detection)，如果在某个下行TTI/子帧上检测到第一控制信息，则该下行TTI/子帧为目标TTI/目标子帧。上述目标TTI/目标子帧的定义方式适用于授权频谱和非授权频谱。进一步地，在一些可行的实施方式中，对于非授权频谱，CPDCCH可能只出现在尾子帧，也可能出现在尾子帧和尾子帧之前的一个下行子帧，例如图5，图5是本发明实施例提供的时域资源的另一示意图。第一控制信息CPDCCH出现在尾子帧和尾子帧之前的一个下行子帧时，若时域资源的时长和/或起始时间单元由第一控制信息指示时，目标子帧(即目标时间单元)可以如图5中的(a)所示，为尾子帧之前的一个下行子帧，也可以如图5中的(b)所示，为尾子帧。图5中的(a)和(b)所示的两种情况下由于目标子帧定义不同，对应的第一时间间隔的长度也不同。
终端设备可以根据第一控制信息确定目标时间单元，可选的，该目标时间单元可以根据第一控制信息指示得到。具体的，目标TTI/目标子帧可以是承载第一控制信息的下行突发的最后一个子帧或最后一个TTI，可能只在最后一个子帧/最后一个TTI出现，也有可能在最后一个子帧/最后一个TTI以及最后一个子帧/最后一个TTI的前一个子帧/TTI都出现，因此只检测存在性可能无法准确确定目标TTI/目标子帧。这种定义方式适用于非授权频谱，终端设备可以通过检测第一控制信息中已有的比特域的不同状态确定哪个子帧是尾子帧，进而确定目标子帧为尾子帧。例如，当第一控制信息为CPDCCH时，现有的CPDCCH中包含用于指示当前子帧/下一子帧中基站占用符号数目的4比特控制信息“Subframe configuration for LAA”。由于CPDCCH只能出现在尾子帧和前一个子帧，且两个子帧中包含的该比特域 的指示状态不同，因此终端设备在某个子帧上检测到CPDCCH后可以确定该子帧是尾子帧，还是下一个子帧是尾子帧。这种通知方式同样适用于第一控制信息为用户特定控制信息或用户组特定的控制信息的场景。
需要说明的是，本发明实施例提供的下行突发为基站占用信道发送的时间上连续的下行传输时间间隔(连续的下行子帧或下行TTI)，并且相邻的两个下行突发之间在时间上不连续。包含所述第一控制信息的下行突发可以也包含数据信息(下行数据信道PDSCH)，也可以不包含数据信息。即，下行突发只发送PDCCH而不发送PDSCH，或者说基站设备只发送UL grant。若该下行突发中包含至少一个子帧，该子帧可以是整子帧(即14符号)或部分子帧(<14符号)，部分子帧包括初始子帧(英文：Initial partial subframe)，或者尾子帧(英文：End partial subframe)。
在一些可行的实施方式中，终端设备确定免调度许可的时域资源的起始时间单元或者第一时间间隔的4种方法具体如下：
方式1：第一时间间隔为预定义时间间隔。
在一些可行的实施方式中，终端设备可以通过确定目标时间单元，结合预定义的第一时间间隔，确定免调度许可的时域资源的起始时间单元。例如，终端设备可以通过检测第一控制信息的存在性(即第一控制信息是否存在)，将检测到第一控制信息的子帧确定为目标子帧，并且将目标子帧之后与目标子帧相隔第一时间间隔的子帧确定为免调度许可的时域资源的起始子帧。可选的，终端设备可以通过第一控制信息中包含的用于指示目标子帧/目标TTI的信息，结合该预定义的第一时间间隔确定免调度许可的时域资源的起始时间单元。例如，当第一控制信息为CPDCCH时，CPDCCH可能在两个子帧(尾子帧和尾子帧的前一个子帧)出现，可以根据CPDCCH中包含的“Subframe configuration for LAA”比特域的指示状态确定下行突发的尾子帧，确定该尾子帧为目标子帧，并且将目标子帧之后与目标子帧相隔第一时间间隔的子帧确定为免调度许可的时域资源的起始子帧。例如，当预定义的第一时间间隔为1个子帧时，将紧跟在尾子帧之后的第一个子帧确定为起始子帧(即时域资源的起始时间单元)。这种通知方式同样适用于第一控制信息为用户特定控制信息或用户组特定的控制信息的场景。
方式2：第一时间间隔由基站设备发送的第二高层信令配置得到。
在一些可行的实施方式中，第一时间间隔由基站设备发送的第二高层信令配置得到时，终端设备确定免调度许可的时域资源的起始时间单元的方法类似于上述方式1，也需要结合确定的目标子帧共同确定起始子帧。其中，上述目标子帧的确定可以通过检测第一控制信息的存在性，也可以通过第一控制信息中用于指示目标子帧/目标TTI的信息确定，不再赘述。方式1与方式2的区别在于，方式2中，第一时间间隔是根据基站设备发送的高层信令配置得到的，增加了时域资源的起始时间单元的确定的灵活性。
方式3：第一时间间隔或者起始时间单元由第一控制信息指示。
在一些可行的实施方式中，可通过第一控制信息包含的比特域来指示第一时间间隔或者起始时间单元。进一步的，当第一控制信息用于指示第一时间间隔时，终端设备结合目标子帧和第一时间间隔确定起始时刻的方式类似于方式1和方式2，不再赘述。
在一些可行的实施方式中，当第一控制信息除了用于指示第一时间间隔或者起始时间 单元之外，还用于指示时域资源的时长时，第一控制信息可以使用两个独立的比特域分别用于指示时域资源的时长和起始时间单元(或第一时间间隔)(如下方式3-1)，也可以使用一个联合的比特域指示时域资源的时长和起始时间单元(或第一时间间隔)(如下方式3-2)。
方式3-1：通过两个独立的比特域分别独立地指示时域资源的时长和起始时间单元(或者第一时间间隔)。
在一些可行的实施方式中，第一控制信息中用于指示时域资源的起始时间单元的比特域和用于指示时域资源的时长的比特域是独立的。也就是说，对于时域资源的时长和起始时间单元中的任意一者，终端设备遍历第一控制信息中相应的比特域中的所有状态可以得到该第一控制信息中包含的所有指示内容。其中，时域资源的起始时间单元的所有状态可以和时域资源的长度的所有状态任意组合。例如，当第一控制信息为CPDCCH时，CPDCCH中包含1比特信息用于指示起始时间单元(或者第一时间间隔)，其包含的两种状态中，状态“0”指示时域资源的起始子帧与下行突发的尾子帧之间的第一时间间隔为1个子帧(起始子帧为尾子帧之后紧跟的第一个子帧)，状态“1”指示时域资源的起始子帧与下行突发的尾子帧之间的第一时间间隔为2个子帧(起始子帧为尾子帧之后的第二个子帧)。另外，CPDCCH中还包含另外2bit的比特域指示时域资源的长度，2bit的比特域编码得到的4种状态可以分别指示时域资源的时长为{0,1,2,3}个子帧，终端设备可以确定时域资源包含从起始子帧或从目标子帧开始，长度为{0,1,2,3}个子帧的时域范围。遍历起始时间单元(或者第一时间间隔)的1比特信息可以获取到时域资源的所有可能的起始位置，遍历长度的2比特信息可以获取到时域资源的所有可能的长度。上述时域资源的起始时间单元的2种状态可以和时域资源的长度的4种状态任意组合，并通过CPDCCH的比特信息指示。这种通知方式同样适用于第一控制信息为用户特定控制信息或用户组特定的控制信息的场景。
方式3-2：通过一个比特域联合地指示时域资源的时长和起始时间单元(或者第一时间间隔)。第一控制信息中采用一个比特域联合地指示时域资源起始时间单元和时域资源的长度。也就是说，对于时域资源的时长和起始时间单元中的至少一者，整个比特域中所有比特用于指示一种时域资源的长度和起始时间单元均有效状态，只选取部分比特并不能指示时域资源的长度或者起始时间单元的有效信息。
在一些可行的实施方式中，考虑到两个指示信息独立指示可能会有冗余，例如，时域资源的长度为0时，第一时间间隔的任一状态都对应相同的用户行为，即认为时域资源为空。时域资源的长度为3时，时域资源的起始子帧与下行突发的尾子帧之间的时间间隔(即第一时间间隔)只能是1个子帧(时间间隔大于4的子帧之后可以被调度，不需要指示为免调度许可资源)，因此可以节省一部分指示状态；例如，当可选长度为{0,1,2,3}个子帧，可选第一时间间隔为{0,1}个子帧时，如下表1所示，表1为上述方式3-2对应的联合指示的一示意表：

Figure PCTCN2017115035-appb-000001
Figure PCTCN2017115035-appb-000002
其中，上述表1中所示的“不可用”表示时域资源不存在(指示终端设备不发送免调度许可的上行信息)，“1”表示第一时间间隔为1个子帧，“2”表示第一时间间隔为2个子帧。同理，长度的表示方式也相同，不再赘述。
另外，时域资源的长度和起始时间单元联合指示的另一个好处是可以指示不连续的时域资源。例如，通过采用比特映射的方式，M个子帧/TTI对应M个比特。例如，考虑第一控制信息之后最多3个子帧可以指示为免调度许可的时域资源(时间间隔大于4的子帧之后可以被调度)，3个比特的比特映射方式如下表2所示，表2为上述方式3-2对应的联合指示的另一示意表。其中，“可用”表示时域资源包含该子帧，“不可用”“表示时域资源不包含该子帧。其中，比特状态“001”代表时域资源的起始子帧与下行突发的尾子帧之间的第一时间间隔为3个子帧(包括子帧#n、子帧#n+1、子帧#n+2以及子帧#n+3)，即第4个子帧(子帧#n+3)可用。比特状态“010”“011”代表第一时间间隔为2个子帧(包括子帧#n、子帧#n+1)，，即第3个子帧(子帧#n+2)和第4个子帧(子帧#n+3)可用。同理，比特状态“100”、“101”、“110”、“111”代表第一时间间隔为1个子帧。

方式4：第一时间间隔或者起始时间单元由第一控制信息隐式地指示。
在一些可行的实施方式中，上述第一时间间隔或者免调度许可的时域资源的起始时间单元可根据第一控制信息中包含的指示信息确定。其中，上述指示信息可包括基站设备在承载第一控制信息的下行突发的最后一个子帧(或者说尾子帧)或最后一个TTI中所占符号数目。或者，上述指示信息也可称为：用于指示基站设备在当前子帧/下一子帧，或当前TTI/下一TTI中占用的符号数目。免调度许可的时域资源的起始时间单元或上述第一时间间隔的 选择所考虑的问题，是给时域资源上传输的PUSCH预留相应的空闲间隔用以执行LBT。由于本发明实施例中所描述的时域资源在下行突发的尾子帧之后，因此主要考虑尾子帧是否有空闲间隔。若基站设备未占满尾子帧的所有下行符号，即尾子帧中存在空闲间隔，则上述时域资源的起始时间单元可以是紧跟在尾子帧之后的第一个子帧，用以提高时域资源的利用率。若基站设备占满所有尾子帧的下行符号，则上述时域资源的起始时间单元时刻要位于尾子帧之后的第一个子帧的起始边界之后，例如第一个子帧的中间符号或者尾子帧之后的第二个子帧，以在尾子帧和时域资源的起始时间单元之间预留空闲间隔用以执行LBT。
需要说明的是，考虑到非授权频谱上已经有公共控制信令用于指示尾子帧以及基站设备在尾子帧中所占的符号数目，终端设备可以根据尾子帧中基站设备所占的符号数目确定起始子帧。若终端设备确定基站设备未占满尾子帧的所有下行符号，则可确定上述时域资源的起始子帧与下行突发的尾子帧之间的第一时间间隔为1个子帧(起始子帧为尾子帧之后紧跟的第一个子帧)。若终端设备确定基站设备占满尾子帧的所有下行符号，则上述时域资源的起始子帧与下行突发的尾子帧之间的第一时间间隔大于1个子帧，包括，起始子帧为尾子帧之后紧跟的第二个子帧，或者，起始子帧为尾子帧之后紧跟的第一个子帧且起始子帧对应的起始位置位于起始子帧所在的完整子帧的中间。例如，当第一控制信息为CPDCCH时，不需要在现有的CPDCCH中额外引入新的比特指示上述时域资源的起始时间单元(或者第一时间间隔)，可以复用现有的CPDCCH中用于指示当前子帧/下一子帧中基站设备所占用的符号数目的4比特控制信息(Subframe configuration for LAA)。
在一些可行的实施方式中，上述第一控制信息除了用于通知当前子帧占用符号数目，以及用于指示哪个子帧是尾子帧外，还可用于隐式地指示时域资源的起始时间单元或第一时间间隔。当上述第一控制信息指示尾子帧所占的符号数目为14或者说占满全部符号时，时域资源的起始子帧与下行突发的尾子帧之间的第一时间间隔为2个子帧。例如，图6中的(b)所示，图6是本发明实施例提供的时域资源的另一示意图。时域资源的起始子帧与下行突发的尾子帧之后的第2个子帧。时域资源的起始子帧与下行突发的尾子帧之间的空闲间隔的子帧用于终端设备针对上行数据信道执行LBT。当尾子帧所占的符号数目小于14或者说未占满全部符号时，例如图6中的(a)所示，第一时间间隔为1个子帧，即时域资源的起始子帧为尾子帧之后紧跟的第一个子帧。在该应用场景中，终端设备可以在尾子帧中的空闲间隔中执行LBT，无需在时域资源的起始子帧与下行突发的尾子帧之间预留一个子帧的空闲间隔。这种通知方式同样适用于第一控制信息为用户特定控制信息或用户组特定的控制信息的场景。
进一步地，在一些可行的实施方式中，终端设备确定时域资源的起始子帧/起始TTI之后，还可确定起始子帧/起始TTI对应的起始位置。类似的，该起始位置可以是：预定义的(方式a)。例如，起始子帧/起始TTI的起始位置总是位于起始子帧/起始TTI所在完整TTI/完整子帧的起始边界0us处(位置1)；或者起始子帧/起始TTI所在完整TTI/完整子帧的起始边界之后25us处(位置2)，或者起始子帧/起始TTI所在完整TTI/完整子帧的起始边界之后(25us+TA)处(位置3)，或者起始子帧/起始TTI所在完整TTI/完整子帧的第二个上行符号起始处(1符号)(位置4)。或者，上述起始位置可以是：基站设备发送的高层信令配置得到的(方式b)。在方式b中，起始位置可选的位置包括上述位置1至4中描述的四种，不再赘 述。或者，上述起始位置可以是：基站设备发送的第一控制信息显式指示的(方式c)。在方式c中，起始位置可选的位置包括上述位置1至4中描述的四种，在此不再赘述。或者，上述起始位置可以是：基站设备发送的第一控制信息中包含的用于指示下行突发尾子帧占用符号数目的比特域隐式指示得到(方式d)。在方式d中，当尾子帧所占的符号数目为14或占满全部符号时，上述起始位置为25us处或1符号处或(25us+TA)处(上述位置2-4)。当尾子帧所占的符号数目小于14或未占满全部符号时，上述起始位置为0us处(上述位置1)。
需要说明的是，终端设备确定起始子帧/起始TTI的方式和确定起始位置的方式是独立的，确定起始子帧/起始TTI的任意一种方式和确定起始位置的任意一种方式搭配。当起始位置不等于0us时，终端设备可以对起始子帧/起始TTI进行速率匹配(英文：Rate matching)，或者直接打掉(英文：Puncture)起始子帧/起始TTI与起始位置之间的时域信号，例如25us，或(25us+TA)，或1符号对应的时域信号。例如，终端设备通过预定义的方式或通过高层信令配置的方式确定起始子帧/起始TTI(方式a或b)，并根据第一控制信息显式指示或隐式指示的方式确定起始位置(方式c或方式d)。或者终端设备根据第一控制信息显式指示或隐式指示的方式确定起始子帧/起始TTI(方式c或d)，并通过预定义或高层配置的方式确定起始位置(方式a或方式b)。
需要说明的是，本发明实施例中免调度许可的时域资源是由第一控制信息动态指示的，虽然在基于调度(英文：UL grant based)的上行传输中，时域资源也是由UL grant信息动态指示，但是，不同于UL grant调度的上行信道的地方在于，本发明实施例中免调度许可指示更近的时域资源，或者说第一时间间隔(或者说第一控制信息所在的下行TTI与其指示的免调度许可时域资源的起始时间单元之间的间隔)相比于基于UL grant调度的方式中的最短调度时延更短。其中，上述UL grant调度中的最短调度时延为UL grant所在的下行TTI/下行子帧与其可能调度的最早的上行信道对应的上行TTI/上行子帧之间的时间间隔。其中，上述最短调度时延可为本发明实施例提供的第二时间间隔。其中，上述第一下行TTI可为承载UL grant的TTI，上述UL grant调度的最早的上行信道对应的上行TTI可设为目标上行TTI，第二时间间隔可为上述第一下行TTI与目标上行TTI之间的时间间隔。
在本发明实施例中，第一下行TTI与免调度时域资源的起始时间单元之间的时间间隔小于上述第二时间间隔，进而可提高资源的利用率，提高上行数据传输的效率。需要说明的是，如果上述UL grant所调度的上行信道多于一个或者说调度的多个上行信道位于多于个上行TTI上，则目标上行TTI对应这些上行信道中时间上最早的一个上行信道。例如，UL grant调度的PUSCH与UL grant所在的子帧/TTI之间的最短调度时延(即第二时间间隔)为4个子帧/TTI。本发明实施例中，第一控制信息所在子帧/TTI与时域资源起始时间单元之间的第一时间间隔可以等于1个子帧/TTI，或者2个子帧/TTI，或者3个子帧/TTI。应理解，本实施例所述的最短调度时延不是针对某一次特定的调度过程中UL grant调度到的最近的上行信道，而是针对基站设备能够调度到的最近的上行信道的能力，例如某一次基站设备在子帧#n发送的UL grant调度的最近的PUSCH在子帧#n+5，但是基站设备的调度到最近的PUSCH的能力是子帧#n的UL grant调度子帧#(n+4)的PUSCH，在其他的调度中可以调度到子帧#(n+4)的PUSCH，此时最短调度时延为4个子帧。终端设备并不像基于调度的上行传输那样在收到UL grant之后才开始组包上行信道，而是提前组包。例如，终端设备可在有了上行业务之 后随时组包，在检测到第一控制信息之后终端设备可以立即发送PUSCH。
需要说明的是，UL grant用于调度上行信道并指示该上行信道的传输格式，其中该上行信道可以是上行业务信道(PUSCH)，也可以是上行控制信道(在Multefire标准中，扩展上行控制信道(英文：extended PUCCH，ePUCCH)也可以被UL grant调度)。
其中，UL grant指示的上行信道的传输格式包括以下至少一项：
该上行信道所占的时域资源；
该上行信道所占的频域资源；
该上行信道的调制编码方式；
包含该UL grant的下行TTI/子帧与该UL grant所调度的上行信道之间的时间间隔。
其中，上行信道所占的时域资源包括至少一个TTI。
考虑到UL grant可能调度至少两个TTI，因此时域资源的时长可以根据UL grant调度的TTI的数目确定。包含该UL grant的下行TTI/子帧与被调度的上行信道之间的时间间隔包括承载该UL grant的TTI与承载该上行信道的TTI(或承载UL grant调度的至少两个TTI的第一个TTI)之间的时间间隔，或者该UL grant的调度时延。考虑到包含该UL grant的下行TTI/子帧与该UL grant所调度的上行信道之间的时间间隔可以大于最短调度时延，在这种情况下UL grant可以包括指示该调度时延的控制信息。UL grant指示的上行信道所占的频域资源包括至少一个物理资源块(英文：Physical Resource Block，PRB)。
需要说明的是，上述调度时延为基站设备发送UL grant的下行TTI/下行子帧与终端设备在上行TTI/上行子帧中发送该UL grant调度的上行数据信道之间的时间间隔。考虑到终端设备的检测能力和组包能力，基于调度的上行数据信道与UL grant之间具有最短调度时延要求，基站设备可以调度比最短调度时延更晚的上行TTI/上行子帧。例如，最短调度时延为4ms时，采用下行链路控制信息(Downlink Control Information，DCI)格式(即DCI format)0/4只能调度与承载UL grant子帧(子帧#n)相隔4ms处的上行子帧(子帧#n+4)，采用DCI format 0A/0B/4A/4B可以调度与承载UL grant子帧相隔大于4ms的上行子帧(例如子帧#n+p，p>4，p是整数)，但是无法调度比最短调度时延更早的上行TTI/上行子帧。当系统的最小TTI是1ms的TTI或一个子帧时，最短调度时延为3ms或4ms，也就是说，子帧#n的UL grant调度的上行数据信道位于子帧#n+3或子帧#n+4。当系统的最小TTI是sTTI时，最短调度时延是k个上行sTTI或下行sTTI，k是大于等于4的整数，也就是说，sTTI#n的UL grant调度的上行数据信道位于sTTI#n+k。
需要说明的是，对于基于调度的上行传输，上行数据信道的传输格式的相关信息，包括时域资源(方式1：承载UL grant的下行TTI/子帧与被调度的PUSCH之间的时间间隔是预定义的，例如4ms。此时，时域资源是隐式指示的。方式2：承载UL grant的下行TTI/子帧与被调度的PUSCH之间的时间间隔是UL grant显式指示的)、频域资源、调制与编码策略(英文：Modulation and Coding Scheme，MCS)、发射功率调整、PUSCH中的解调参考信号(英文：DeModulation Reference Signal，DMRS)等，都是由UL grant通知给终端设备。终端设备根据UL grant指示的传输格式信息进行组包，在指示的时域、频域资源上发送PUSCH。然而，对于免调度许可的上行传输，上述上行数据信道的传输格式包含的信息无法由基站通过UL grant动态指示。本发明实施例提供的实现方式不同于UL grant调度的PUSCH的地方 在于，第一控制信息仅用于指示终端设备可用的时域资源，而除时域资源以外，终端设备发送上行数据信道对应的传输格式相关的至少一项其他信息，则不是根据第一控制信息确定。具体的，上述上行数据信道的传输格式相关的至少一项其他信息可以是预定义的，也可以是基于基站设备发送的第三高层信令配置得到。
S104，终端设备在上行数据信道上发送数据信息。
S105，基站设备在上行数据信道上接收所述终端设备发送的数据信息。
在一些可行的实施方式中，上述上行数据信道的传输格式相关的信息包括以下至少一项：
上行数据信道所占的频域资源；
上行数据信道的调制编码方式；
上行数据信道的发射功率；
上行数据信道中解调参考信号的码序列；
上行数据信道承载的传输块大小(英文：Transmission Block Size，TBS)等。
或者说，基于调度的PUSCH的上行数据信道的传输格式信息都是由同一个指示信息(UL grant)指示的，而本实施例中的免调度许可的PUSCH的上行数据信道的传输格式的一部分信息(即免调度许可的时域资源)是由基站设备发送的第一控制信息(即动态信令)指示的，而另一部分是预定义的，或者另一部分由另一个信令(如基站设备发送的第三高层信令)配置得到的。
需要说明的是，上述上行数据信道所占的频域资源包含至少一个PRB，上述解调参考信号的码序列包括DMRS的正交覆盖码(英文：Orthogonal Cover Code，OCC)以及循环移位(英文：Cyclic Shift，CS)中的至少一项。从介质访问控制(Media Access Control，MAC)层发往物理层的数据是以传输块(英文：Transport Block,TB)的形式组织的，数据信息以TB的形式承载在上行数据信道上发送。TBS为对应特定频域资源(具体可为PRB数目)以及特定调制编码方式的TB中包含的有效数据信息(编码之前的数据信息)量。终端设备可以根据上行数据信道所占的频域资源和调制编码方式确定TBS，也可以根据预定义或基站设备发送的第三高层信令配置的信息确定TBS。例如，TBS的大小是预定义的，或者是基于基站设备发送的第三高层信令配置的，此时传输格式相关信息中可以不包含MCS信息。
需要说明的是，现有的eLAA系统中支持两级调度(英文：two-stage scheduling)。基站设备在下行突发中包含的UL grant发送调度信息，但是调度时延并不是PUSCH相对于ULgrant所在子帧的时延，而是PUSCH相对于CPDCCH所在子帧的时延。终端设备在仅收到ULgrant之后并不会发送PUSCH，还要通过检测到CPDCCH才进行发送数据信息。其中，由ULgrant指示PUSCH相对于CPDCCH的时间间隔，由CPDCCH触发PUSCH上的数据信息的发送。相比于两级调度方案，本发明实施例提供的实现方式中描述的第一控制信息也用于指示时域资源，但是相比于两级调度中的CPDCCH，本发明实施例中所描述的免调度许可的时域资源(包括时域资源的长度和起始时刻等参数可完全由第一控制信息指示)。然而，在两级调度中，时域资源的长度由另一个控制信息UL grant指示，时域资源的起始时刻根据CPDCCH和另一个控制信息UL grant共同确定。
需要说明的是，考虑到在非授权频谱上发送数据信息的情况，若终端设备确定在免调 度许可的时域资源上的至少一个子帧或TTI上发送上行数据信息，则上行数据信道发送之前需要在承载该上行数据信息的上行数据信道所在的载波上执行LBT。终端设备检测到信道空闲才可以立即发送该上行数据信息，其中LBT类型包括基于随机回退的CCA和单时隙CCA中的一种，在此不再赘述。
在本发明实施例中，基站设备可向终端设备发送第一控制信息，通过第一控制信息指示在承载第一控制信息的下行TTI或下行子帧之后的免调度许可资源。第一控制信息指示的免调度许可资源中的起始TTI或者起始子帧与上述下行TTI或者下行子帧之间的时间间隔较短，终端设备可在免调度许可资源上发送上行数据信息，时域资源的利用率更高。在本发明实施例中，终端设备可在比UL grant调度模式下的调度时延更短的时间内发送上行数据信息，提高了上行数据信息的发送效率，上行数据信息的发送更灵活，适用性更高。

本领域普通技术人员可以理解实现上述实施例方法中的全部或部分流程，是可以通过计算机程序来指令相关的硬件来完成，所述的程序可存储于计算机可读取存储介质中，该程序在执行时，可包括如上述各方法的实施例的流程。其中，所述的存储介质可为磁碟、光盘、只读存储记忆体(Read-Only Memory，ROM)或随机存储记忆体(Random Access Memory，RAM)等。
以上所揭露的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明权利要求所作的等同变化，仍属本发明所涵盖的范围。
