Description

一种上行传输方法、装置、用户终端及基站
本申请要求于2016年04月21日提交中国专利局、申请号为201610266884.4、发明名称为“一种上行传输方法、装置、用户终端及基站”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种上行传输方法、装置、用户终端及基站。
背景技术
移动通信系统，是指运营商通过部署无线接入网设备(如基站)，和核心网设备(如归属位置寄存器，Home Location Register，HLR)等，为用户终端(如手机)提供通信服务的系统。移动通信经历了第一代、第二代、第三代、第四代。第一代移动通信是指最初的模拟、仅限语音通话的蜂窝电话标准，主要采用的是模拟技术和频分多址(Frequency Division Multiple Access，FDMA)的接入方法；第二代移动通信引入了数字技术，提高了网络容量、改善了话音质量和保密性，以“全球移动通信系统”(Global System for Mobile Communication，GSM)和“码分多址”(Code Division Multiple Access，CDMA IS-95)为代表；第三代移动通信主要指CDMA2000，WCDMA，TD-SCDMA三种技术，均是以码分多址作为接入技术的；第四代移动通信系统的标准在国际上相对统一，为国际标准化组织3GPP制定的长期演进(Long Term Evolution/Long Term Evolution-Advanced，LTE/LTE-A)，其下行基于正交频分多直接入(Orthogonal Frequency Division Multiple Access，OFDMA)，上行基于单载波频分多直接入(Single Carrier–Frequency Division Multiple Access，SC-FDMA)的接入方式，依据灵活的带宽和自适应的调制编码方式，达到了下行峰值速率1Gbps，上行峰值速率 500Mbps的高速传输。
下图1简要示出了移动通信网络的基本架构，终端通过接入网与核心网通信连接。
MulteFire为在LTE R13LAA下行传输方法的基础上，新定义上行传输方法，并且可以独立工作于非授权频段的LTE技术，即stand-alone LTE-U。现有LTE中，PUSCH(物理上行共享信道)传输由eNB(演进的节点B，即基站)发送UL grant(上行授权)进行调度。
例如在LTE FDD系统中，eNB子帧n发送UL grant，UE在子帧n+4发送PUSCH。在LTE R14eLAA和MulteFire中，支持在非授权频段传输上行数据，由于在非授权频段发送上行数据前需要进行LBT(Listen Before Talk，先听后说)，因此对于UL grant和PUSCH都需要进行LBT。
在eLAA和MulteFire中，eNB选择的接入优先级决定了LBT参数和最大允许信道占用时间(随机退避时间越长，接入优先级越低，最大允许的信道占用时间越长；反之同理)，其中最大允许信道占用时间在eLAA/LAA中称之为MCOT，在MulteFire中称之为传输机会(TXOP，Transmission Opportunity)，后续统一用TXOP来描述。
如图2所示，当UE被调度的PUSCH，在eNB发送下行所采用LBT cat-4对应的TXOP之内(即eNB的下行只占用了一部分TXOP，剩余部分的TXOP可供上行使用)时，UE的LBT可以仅进行25us长的LBT cat-2；而当UE被调度的PUSCH在eNB发送下行所采用LBT对应的TXOP之外时，MulteFire中规定UE需要进行LBT cat-4。此外，在eLAA和MulteFire中也都支持多个子帧上的PUSCH传输通过一个UL grant来进行调度的方式。那么，当采用一个UL grant来调度多个子帧上的PUSCH传输时，由于会受到eNB的TXOP的限制，只能调度到TXOP以内，而调度到eNB的TXOP之外的终端由于使用另一类LBT需要单独的UL grant进行调度，因此增加了 UL grant的数量，增加了下行资源开销。

其中，上行调度信息中携带有表征基站为用户终端调度的上行信道所占用资源位置的信息，如被调度的上行信道所占用的资源位置的编号等，该上行信道可以是传输上行数据信号的上行传输信道，如PUSCH，亦可以是传输控制信号的上行传输信道，如ePUCCH或者sPUCCH。
其中，基站所占用的传输机会TXOP是指基站最大允许信道占用时间，基站TXOP的指示信息中携带有表征基站TXOP所在位置的指示信息，具体地，指示信息至少包括：传输机会TXOP所占用的时间长度信息、传输机会TXOP所占用的剩余时间长度信息、监听类型信息(如LBT cat-2或LBT cat-4)、监听类型切换信息、以及监听类型与被调度的上行信道的关系中的至少一项。
步骤32：根据上行调度信息，确定基站为用户终端调度的上行信道的位置。
由于上行调度信息中携带有基站为用户终端调度的上行信道所占用资源位置的信息，因此用户终端可根据上行调度信息解析出基站为用户终端所调度的上行信道所在的位置。其中，如图4所示，上行信道中包括多个跨基站TXOP的传输子帧，即多个传输子帧中一部分传输子帧位于基站的TXOP内，其他传输子帧位于基站的TXOP外，也就是说为用户终端调度的传输子帧数目不受基站的TXOP限制。值得指出的是，用户终端可在基站为其调度的上行传 输信道内进行上行数据的传输；其中，基站为用户终端调度的上行信道包括：位于基站的TXOP内的上行传输信道，以及位于基站的TXOP外的上行传输信道(又可称为用户终端的传输机会)。
步骤33：根据上行信道的位置和传输机会的指示信息，确定上行信道的监听类型。
用户终端在利用基站为其调度的上行信道进行上行数据传输之前，需要对对应的上行信道进行监听，只有监听到该上行信道空闲时，才能通过该上行信道进行传输。其中，上行信道处于传输机会内时采用的监听类型，与上行信道处于传输机会外时采用的监听类型不同。也就是说，用户终端监听基站为其调度的位于基站的TXOP内的上行信道时所采用的监听类型，与监听基站为其调度的位于基站的TXOP外的上行信道时所采用的监听类型不同。根据为用户终端调度的上行信道与基站的TXOP的位置关系，确定对应上行信道的监听类型，并对其空闲状态进行监听。
步骤34：在采用上行信道的监听类型监听到的处于空闲状态的上行信道上，向基站发送上行数据。
当用户终端采用合适的监听类型监听到对应的上行信道处于空闲状态，则利用该上行信道向基站发送待传输的上行数据。这样，用户终端根据基站发送的上行调度信息和传输机会的指示信息，确定为其调度的上行信道与基站传输机会的位置关系，从而自动确定和切换不同位置处的监听类型，并在监听到信道空闲时向基站发送上行数据。这样，基站在为用户终端调度多个子帧时，调度的子帧数目不受当前的传输机会的限制，仅需要基站发送一次上行调度信息即可，降低了下行信道资源开销，节省了网络资源。
第二实施例
如图5所示，本申请的第二实施例提供了一种上行传输方法，具体包括以下步骤：
步骤51：向用户终端当前接入的基站发送一上行调度请求；
步骤52：接收基站根据上行调度请求发送的、携带有基站当前 占用的传输机会的指示信息的上行调度信息。
步骤53：根据上行调度信息，确定基站为用户终端调度的上行信道的位置。
步骤54：根据上行信道的位置和传输机会的指示信息，确定上行信道的监听类型。
步骤55：在采用上行信道的监听类型监听到的处于空闲状态的上行信道上，向基站发送上行数据。
这里所说的是，将基站的TXOP的指示信息承载至上行调度信息中，具体地TXOP的指示信息至少包括：传输机会所占用的时间长度信息、传输机会所占用的剩余时间长度信息、监听类型信息、监听类型切换信息、以及监听类型与被调度的上行信道的关系中的至少一项。
其中，当上行调度信息中携带有监听类型信息时，指示上行调度信息中每个子帧对应的LBT类型，例如调度M个子帧，通过M比特的bitmap分别指示每个子帧的LBT类型(0表示LBT cat-2，1表示LBT cat-4)。
其中，当上行调度信息中携带有监听类型切换信息时，指示上行调度信息中第一个被调度子帧对应的LBT类型和LBT类型切换的子帧，例如当支持一次LBT类型切换时，用1比特用于指示第一个被调度子帧的LBT类型，L比特指示范围在第2至2L的某个子帧进行LBT类型切换(当指示第1个子帧时表示不进行LBT类型切换)，具体例如1比特0表示第一个被调度的子帧进行LBT cat-2，3比特010的LBT类型切换指示第3个被调度的子帧前进行LBT的类型切换为LBT cat-4。
这样，用户终端根据基站发送的携带有基站TXOP指示信息的上行调度信息，确定为其调度的上行信道与基站TXOP的位置关系，从而自动确定和切换不同位置处的监听类型，并在监听到信道空闲时向基站发送上行数据。这样，基站在为用户终端调度多个子帧时，不受当前的基站TXOP的限制，仅需要基站发送一次上行调度信息 即可，降低了下行信道资源开销，节省了网络资源。
第三实施例
如图6所示，本申请的第三实施例提供了一种上行传输方法，具体包括以下步骤：
步骤61：向用户终端当前接入的基站发送一上行调度请求；
步骤62：接收基站根据上行调度请求发送的上行调度信息以及基站通过公共信道发送的基站当前占用的传输机会的指示信息。
步骤63：根据上行调度信息，确定基站为用户终端调度的上行信道的位置。
步骤64：根据上行信道的位置和传输机会的指示信息，确定上行信道的监听类型。
步骤65：在采用上行信道的监听类型监听到的处于空闲状态的上行信道上，向基站发送上行数据。
这里所说的是，基站发送给用户终端的上行调度信息中未承载基站TXOP的指示信息，即上行调度信息和基站TXOP的指示信息分别单独传输。具体地，上行调度信息和基站TXOP的指示信息可通过不同的信道传输，例如基站TXOP的指示信息可承载至其他公共信道(如C-PDCCH)进行传输。基站的TXOP的指示信息至少包括：传输机会所占用的时间长度信息、传输机会所占用的剩余时间长度信息、监听类型信息、监听类型切换信息、以及监听类型与被调度的上行信道的关系中的至少一项。例如，用户通过其他公共信道获取基站TXOP的指示信息，该指示信息中携带有基站TXOP的长度信息，用户终端根据基站TXOP的长度信息以及上行调度信息中指示的被调度的上行子帧位置来判断在基站TXOP之内的上行传输前进行LBT cat-2，在基站TXOP之外的上行传输前进行LBT cat-4。
例如，如图7所示，C-PDCCH在基站eNB的TXOP中的下行子帧(D表示)发送，并指示当前子帧后还有多少个子帧在eNB的TXOP之内，假设在eNB的TXOP内前半段用于传输下行子帧，后 半段用于传输上行子帧(U表示)，如在倒数第二个下行子帧中发送的C-PDCCH中指示当前子帧后eNB的TXOP包括N个子帧，在倒数第一个下行子帧中发送的C-PDCCH中指示当前子帧后eNB的TXOP包含N-1个子帧。用户终端可根据为自身调度的上行信道的位置以及eNB的TXOP的子帧数目和位置，确定不同子帧的监听类型，并在监听到信道空闲时向基站发送上行数据。这样，基站在为用户终端调度多个子帧时，不受当前的基站的TXOP的限制，仅需要基站发送一次上行调度信息即可，降低了下行信道资源开销，节省了网络资源。
第四实施例
基于第一实施例至第三实施例，如图8所示，本申请的第四实施例提供了一种上行传输方法，具体包括以下步骤：
步骤81：获取基站发送的上行调度信息以及基站当前占用的传输机会的指示信息。
步骤82：根据上行调度信息，确定基站为用户终端调度的上行信道的位置。
步骤83：当上行信道的位置位于传输机会内时，确定上行信道的监听类型为第一监听类型。
步骤84：当上行信道的位置位于传输机会外时，确定上行信道的监听类型为第二监听类型。
这里的第二监听类型与第一监听类型不同。
其中，为用户终端调度的上行信道包括：位于基站传输机会内的第一上行信道和位于基站传输机会外的第二上行信道。也就是说，基站为用户终端调度的上行信道包括：位于eNB的TXOP内的第一上行信道和位于eNB的TXOP外的第二上行信道。由于不同位置处的上行信道所需要的监听类型不同，因此涉及到为用户终端调度的跨eNB的TXOP的上行信道的监听类型切换的问题。
具体地，采用第一监听类型监听第一上行信道是否处于空闲状态；当第一上行信道处于空闲状态时，通过第一上行信道向基站发 送上行数据。即当为用户终端调度的上行信道的起始位置位于eNB的TXOP内时，采用25us长的LBT Cat-2对其进行监听，当监听到该段上行信道处于空闲状态时，将待传输的上行数据信号承载至其中并发送至基站。
当第一上行信道结束、第二上行信道开始时，将第一监听类型切换至第二监听类型；采用第二监听类型监听第二上行信道是否处于空闲状态；当第二上行信道处于空闲状态时，通过第二上行信道向基站发送上行数据。即上行信道到达eNB的TXOP结束处时，需要切换监听类型。具体地，当上行信道到达eNB的TXOP结束位置、位于eNB的TXOP外的上行信道开始时，将监听类型由25us长的LBT Cat-2切换至监听时间更长的LBT Cat-4。
其中，将监听类型切换至第二监听类型后，还需要选择第二监听类型的接入等级，除非第二监听类型只定义了一种信道接入等级。其中，当第二监听类型定义了多种信道接入等级时，用户终端可根据eNB的TXOP的指示信息以及待传输的上行数据确定第二监听类型的接入等级。具体地，当标准定义了第二监听类型(如LBT cat-4)支持多个接入等级(即接入优先级)时，可以通过eNB来指示UE进行的LBT cat-4时对应的信道接入优先级时，例如可以通过RRC及DCI(DL grant、UL grant、C-PDCCH等方式)进行配置或指示。也可以由UE选择LBT cat-4的信道接入优先级，UE可以根据eNB的TXOP之外的被调度子帧数量及是否需要与其他UE进行复用等要求，选择信道接入优先级。
其中，在对上行信道进行监听时需要预留监听信道来进行监听，具体监听过程可参照以下方式实现：
对于第一上行信道和第二上行信道的切换，预留第一上行信道的后N个子帧或符号，和/或第二上行信道的前N个子帧或符号为监听信道；其中，N为正整数；在监听信道上采用第二监听类型监听第二上行信道是否处于空闲状态。即如图9所示，在eNB的TXOP的最后N个子帧或OFDM符号、或者eNB的TXOP之后的N个子 帧或OFDM符号留空作为监听信道，用于用户终端做LBT cat-4的监听，其中n＝1、2、3等。当用户终端在eNB的TXOP之外的信道接入优先级所需要的最短LBT时间(包括T-R-T切换时延)也超过了n的最大值时，用户终端可以放弃被调度于eNB的TXOP之后的第一个子帧的上行传输。但是如果eNB能够获知UE的信道接入优先级时，UE可以将eNB的TXOP之外的第一个子帧的传输从下一子帧开始。
进一步地，位于eNB的TXOP外的第二上行信道可以包括多个上行子信道(即多个用户终端UE TXOP)，上述提到用户终端采用第二监听类型(LBT-Cat-4)对每个UE TXOP的起始位置(或者称为UE的TXOP中的第一个传输子帧)进行监听，除此之外，用户终端还需要对同一个UE TXOP内的其他传输子帧进行监听。具体地，预留第二上行信道中除第一个上行子信道外的其他上行子信道的相邻位置处N个子帧或符号作为子监听信道；在子监听信道上监听第二上行信道的其他上行子信道是否处于空闲状态。其中，值得指出的是，多个UE TXOP的起始传输子帧独立进行LBT cat-4监听，而同一UE TXOP内的传输子帧可通过LBT cat-2进行监听。
以上介绍的是基站为用户终端调度的上行信道的起始位置位于eNB的TXOP内，结束位置位于eNB的TXOP外的场景。但是当为用户调度的上行信道的时间长度大于或等于基站的TXOP的时间长度时，可能存在上行信道跨越两个eNB的TXOP，即上行信道的起始位置位于eNB的TXOP内，结束位置位于eNB的下一个TXOP内的场景，那么从TXOP外切换至下一个TXOP时，同样需要进行监听类型切换。
采用第二监听类型监听第二上行信道是否处于空闲状态；当第二上行信道处于空闲状态时，通过第二上行信道向基站发送上行数据。即当为用户终端调度的上行信道位于eNB的TXOP外(即UE的TXOP)时，采用LBT Cat-4进行对其进行监听，当监听到对应的UE的TXOP处于空闲状态时，将待传输的上行数据信号承载至其中 并发送至基站。
当第二上行信道结束、第一上行信道开始时，将第二监听类型切换至第一监听类型；采用第一监听类型监听第一上行信道是否处于空闲状态；当第一上行信道处于空闲状态时，通过第一上行信道向基站发送上行数据。即当UE的TXOP到达eNB的下一个TXOP时，需要切换监听类型。具体地，如图10所示，当UE的TXOP过后并没有传输完时，eNB成功竞争得到信道，eNB的下一个TXOP开始，根据eNB发送的上下行切换指示(例如TDD配置信息)，当仍有被调度的上行传输对应eNB的新的TXOP时，UE准备在上行子帧传输并将LBT cat-4切换为LBT cat-2进行信道监听。
步骤85：在采用上行信道的监听类型监听到的处于空闲状态的上行信道上，向基站发送上行数据。
综上，基站将自身占用的传输机会的指示信息发送给用户终端，用户终端根据上行调度信息和传输机会的指示信息，确定为其调度的上行信道与基站传输机会的位置关系，从而自动确定和切换不同位置处的监听类型。当用户终端采用合适的监听类型监听到对应的上行信道处于空闲状态，则利用该上行信道向基站发送待传输的上行数据。这样，用户终端根据基站发送的上行调度信息和传输机会的指示信息，确定为其调度的上行信道与基站传输机会的位置关系，从而自动确定和切换不同位置处的监听类型，并在监听到信道空闲时向基站发送上行数据。这样，基站在为用户终端调度多个子帧时，调度的子帧数目不受当前的传输机会的限制，仅需要基站发送一次上行调度信息即可，降低了下行信道资源开销，节省了网络资源。

第九实施例
以上第一实施例至第八实施例分别从基站侧介绍了本申请的上行传输方法、装置、用户终端、非暂态计算机可读存储介质及计算机程序产品，下面本实施例将从对应的基站侧介绍本申请的上行传输方法。
如图13所示，本申请的实施例提供了一种上行传输方法，具体包括：
步骤131：向用户终端发送上行调度信息以及基站当前占用的传输机会的指示信息。
以使用户终端根据上行调度信息，确定基站为用户终端调度的上行信道的位置；继而根据上行信道的位置和传输机会的指示信息，确定上行信道的监听类型；其中，上行信道处于传输机会内时采用的监听类型，与上行信道处于传输机会外时采用的监听类型不同。
其中，上行调度信息中携带有表征基站为用户终端调度的上行信道所占用资源位置的信息，如被调度的上行信道所占用的资源位置的编号等，该上行信道可以是传输上行数据信号的上行传输信道，如PUSCH，亦可以是传输控制信号的上行传输信道，如ePUCCH或 者sPUCCH。
其中，基站所占用的传输机会TXOP是指基站最大允许信道占用时间，基站TXOP的指示信息中携带有表征基站TXOP所在位置的指示信息，具体地，指示信息至少包括：传输机会TXOP所占用的时间长度信息、传输机会TXOP所占用的剩余时间长度信息、监听类型信息(如LBT cat-2或LBT cat-4)、监听类型切换信息、以及监听类型与被调度的上行信道的关系中的至少一项。
其中，向用户终端发送上行调度信息以及基站当前占用的传输机会的指示信息的步骤包括：获取基站覆盖下的用户终端发送的上行调度请求；根据上行调度请求，向用户终端发送携带有基站当前占用的传输机会的指示信息的上行调度信息。
其中，当上行调度信息中携带有监听类型信息时，指示上行调度信息中每个子帧对应的LBT类型，例如调度M个子帧，通过M比特的bitmap分别指示每个子帧的LBT类型(0表示LBT cat-2，1表示LBT cat-4)。这样，用户终端根据基站发送的携带有基站TXOP指示信息的上行调度信息，确定为其调度的上行信道与基站TXOP的位置关系，从而自动确定和切换不同位置处的监听类型。
此外，向用户终端发送上行调度信息以及基站当前占用的传输机会的指示信息的步骤还可参照以下方式实现：获取基站覆盖下的用户终端发送的上行调度请求；根据上行调度请求，向用户终端发送上行调度信息；并通过公共信道向用户终端发送基站当前占用的传输机会的指示信息。
这里所说的是，基站发送给用户终端的上行调度信息中未承载基站TXOP的指示信息，即上行调度信息和基站TXOP的指示信息分别单独传输。具体地，上行调度信息和基站TXOP的指示信息可通过不同的信道传输，例如基站TXOP的指示信息可承载至其他公共信道(如C-PDCCH)进行传输。例如，用户通过其他公共信道获取基站TXOP的指示信息，该指示信息中携带有基站TXOP的长度信息，用户终端根据基站TXOP的长度信息以及上行调度信息中指 示的被调度的上行子帧位置来判断TXOP之内的上行传输前进行LBT cat-2，TXOP之外的上行传输前进行LBT cat-4。这样，基站在为用户终端调度多个子帧时，不受当前的基站TXOP的限制，仅需要基站发送一次上行调度信息即可，降低了下行信道资源开销，节省了网络资源。
步骤132：接收用户终端在采用上行信道的监听类型监听到的处于空闲状态的上行信道上发送的上行数据。
综上，基站将自身占用的传输机会的指示信息发送给用户终端，用户终端根据上行调度信息和传输机会的指示信息，确定为其调度的上行信道与基站传输机会的位置关系，从而自动确定和切换不同位置处的监听类型。当用户终端采用合适的监听类型监听到对应的上行信道处于空闲状态，则利用该上行信道向基站发送待传输的上行数据。这样，用户终端根据基站发送的上行调度信息和传输机会的指示信息，确定为其调度的上行信道与基站传输机会的位置关系，从而自动确定和切换不同位置处的监听类型，并在监听到信道空闲时向基站发送上行数据。这样，基站在为用户终端调度多个子帧时，调度的子帧数目不受当前的传输机会的限制，仅需要基站发送一次上行调度信息即可，降低了下行信道资源开销，节省了网络资源。
