Description

一种基于授权辅助接入系统的上行数据的发送方法及设备
本申请要求于2017年06月26日提交中国专利局、申请号为201710496421.1、申请名称为“一种适用于eLAA系统的上行数据传输方法”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
本申请涉及通信领域，尤其涉及一种基于授权辅助接入系统的上行数据的发送方法及设备。
背景技术
授权频谱辅助接入(licensed-assisted access，LAA)系统是一种基于授权频段辅助的用于接入非授权频段的长期演进(long term evolution，LTE)系统。LAA通过将LTE接入到非授权频段，可以有效解决LTE系统在授权频段的频谱紧张问题。
在第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)无线接入网络(radio access network，RAN)第89次会议中，针对LAA上行起始位置达成了协议，终端(user equipment，UE)在发送上行数据时，可以将Release14规定的上行数据起始发送位置(例如：符号0)或者上行子帧的符号7作为数据发送位置。
然而，现有技术中，若符号0和符号7为数据发送位置，由于UE发送上行数据需要进行先听后发(listen-before-talk，LBT)抢占信道，而UE在符号0进行LBT的结果基站不知道，因此基站需要再每个上行子帧的符号0和符号7进行检测，增加了检测复杂度和功耗。而UE需要在每个子帧的符号0和符号7前进行LBT，同样也增加了UE的功耗。

具体实施方式
本申请实施例提供了一种基于授权辅助接入系统的上行数据的发送方法和相关设备，用于解决现有技术中检测复杂度和功耗较大的问题。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)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。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
随着业务量的急剧增大，授权频谱可能难以满足业务量的需求。3GPP RAN的62次全会讨论了关于非授权频谱综合的研究，主要目的是研究利用在非授权频谱上的LTE的Non-standalone(非独立)部署，所谓Non-standalone是指在非授权频谱上的通信要和授权频谱上的服务小区相关联。对于非授权频谱，考虑到其干扰水平的不可控制/预测，先听后发(listen before talk，LBT)技术能够有效的避免LTE系统和其他系统间的干扰以及LTE系统内部不同运营商设备之间的干扰，LBT技术可以理解为要传输数据的站点首先对信道上有无载波进行监听，以确定是否有别的站点来传输数据。假如信道空闲，该站点便可传输数据；否则，该站点将避让一段时间后再做尝试。实际应用中，可以将时间按固定的帧长度划分，在一个固定帧长度中进一步划分为信道占用时间和空闲周期，其中，信道占用时间是设备可以发送数据的持续时间，在空闲时间的最后是空闲信道评估(clear channel assessment，CCA)时隙，用于检测信道是否空闲。
现有技术中，UE可以将上行子帧的符号0或者符号7作为数据发送位置，在发送上行数据之前，UE需通过LBT技术抢占信道，从UE的角度，对每个上行子帧都进行多次LBT检测，增加了UE的功耗和接入信道的复杂度；从基站的角度，由于基站不知道UE在符号0进行LBT检测的结果，故基站需要在每个上行子帧的符号0和符号7进行检测，增加了基站侧的检测复杂度和功耗；同时，如果在每个上行子帧中都采用动态信令指示多个起始 位置，导致信令开销增大。
有鉴于此，本申请实施例提供了一种基于授权辅助接入系统的上行数据的发送方法，用于降低检测的复杂度和设备功耗，通过在上行数据发送过程中，由基站配置时间窗口配置信息的方式，即基站设置起始接入信道的时间窗口，只有在该时间窗口内的子帧上，终端才能在多个开始位置接入信道，可以理解为，若子帧包含于基站设置的时间窗口内，则该子帧的第一位置和第二位置均为上行数据发送位置；若子帧不包含于基站设置的时间窗口内，则该子帧的起始位置才为上行数据发送位置。本申请中，基站配置时间窗口配置信息的方式有多种，包括：周期性的配置时间窗口配置信息和非周期性的配置时间窗口配置信息，下面将结合具体的实施例对上述两种方式进行说明。
请参阅图1，为本申请实施例中基于授权辅助接入系统的上行数据的发送方法的流程图，且在本实施例中，基站周期性的配置时间窗口配置信息，该方法包括：
101、基站配置时间窗口配置信息。
为实现终端不需在每个子帧都进行多次LBT检测，且基站也不需在每个子帧的第一位置和第二位置进行检测，基站配置时间窗口配置信息，该时间窗口配置信息用于指示目标子帧组，使得终端可以在该目标子帧组内的任意子帧的第一位置或者第二位置进行LBT接入信道，可以理解的是，该目标子帧组至少包括一个目标子帧，且该目标子帧组中的子帧可以是连续的子帧，在本申请实施例中，可以采用LTE帧结构，发送的信号在时域上以OFDM符号为单位，即终端在子帧的OFDM符号位置上发送上行数据，实际应用中，该第一位置可以为OFDM符号0，第二位置可以为OFDM符号7；或者第一位置可以为OFDM符号7，第二位置可以为OFDM符号0，具体此处不做限定。
另外，当该时间窗口配置信息由基站周期性的配置时，该时间窗口配置信息包括下列参数中的一种或者多种：时间窗口的大小、时间窗口的周期和时间窗口的偏移量，且时间窗口的大小即为目标子帧组中所包含的目标子帧的个数。如图2所示，为本申请实施例提供的一种可能的周期性的时间窗口示意图，每个白色框代表一个目标子帧，即该时间窗口中包括3个目标子帧，且时间窗口的周期为6个子帧。
102、基站对时间窗口配置信息进行加扰。
基站将配置的时间窗口配置信息用新的无线网络临时标识(radio network tempory identity，RNTI)进行加扰，该新的RNTI用于标识时间窗口配置信息，其中，新的RNTI可以理解为一个加扰序列，基站对时间窗口配置信息进行加扰，即用一个加扰序列来干扰该时间窗口配置信息，使该时间窗口配置信息变化，只有采用相同的加扰序列来解扰才能复原，故基站通过新的RNTI来加扰时间窗口配置信息以使得终端能区分出该时间窗口配置信息。
103、基站发送第一消息到终端。
基站对时间窗口配置信息进行加扰后，将该时间窗口配置信息通过第一消息发送到终端，其中，该第一消息可以为半静态调度信令，例如无线资源控制(radio resource control，RRC)信令，或者为介质访问控制(media access control，MAC)CE信令，具体此处不做限定。
其中，本申请实施例中，终端又可以称之为用户设备(User Equipment，UE)，可以是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。常见的终端例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等。
104、基站发送第一动态信息到终端。
另外，基站还向终端发送第一动态信息，该第一动态信息至少携带触发开关。当该触发开关处于打开状态时，基站配置的时间窗口配置信息才有效，即终端可在时间窗口配置信息指示的目标子帧上的第一位置或者第二位置接入信道；当触发开关处于关闭状态时，基站配置的时间窗口配置信息无效，即终端只能在子帧的起始位置上接入信道。
具体地，基站通过物理下行通道(physical downlink control channel，PDCCH)的动态信令发送给终端，即该第一动态信息可以为PDCCH上承载的下行控制信息(downlink control information，DCI)。
105、基站向终端发送至少两个连续子帧中相同的指示信息。
鉴于非授权频谱可靠性低，为了保证更高的可靠性，基站可通过至少两个连续的子帧向终端发送相同的指示信息，该指示信息用于指示终端开启时间窗口模式，即指示终端在目标子帧的第一位置或者第二位置接入信道。例如，在图2所示的时间窗口示意图中，将一个周期内的子帧分别命名为子帧0～5，其中，子帧3～5包含于时间窗口内，若终端在子帧5发送上行数据，则基站在子帧0和子帧1两个子帧的PDCCH中打开触发开关，当终端接收到基站通过子帧0和子帧1发送的两个连续相同的指示信息时，终端确认基站发送的时间窗口配置信息有效，则终端开启时间窗口模式。
106、终端确定发送上行数据的位置。
终端接收到基站发送的时间窗口配置信息，并通过两个连续相同的指示信息确认该时间窗口配置信息有效后，终端采用新的RNTI对该时间窗口配置信息进行解扰以进行复原得到时间窗口配置信息。终端在时间窗口配置信息所指示的目标子帧的第一位置或第二位置通过LBT技术中的CCA时间窗检测信道是否空闲，实际应用中，确定信道是否空闲的方式有多种，例如，判断信道能量(received signal strength，RSSI)是否低于预置门限，若是，则表示信道空闲，终端可以立即接入信道以发送上行数据；或者判断信道空闲时间是否大于预设时间，若是，则表示信道空闲，终端接入信道并发送上行数据，其中，终端在接入信道之前需进行的LBT检测为现有技术，具体本申请不做赘述。
若终端在第一位置或者第二位置检测到信道空闲，则终端将当前为位置作为数据发送位置来发送上行数据。
本申请实施例中，基站周期性的配置时间窗口配置信息，使得终端只在时间窗口配置信息所指示的目标子帧上才开启时间窗口模式，降低了基站和终端的功耗和实现复杂度，并减少了动态信令的开销，缩短了数据传输延时。
请参阅图3，为本申请实施例中基于授权辅助接入系统的上行数据的发送方法的另一流程图，且在本实施例中，基站非周期性的配置时间窗口配置信息，该方法包括：
301、基站配置时间窗口配置信息。
当该时间窗口配置信息由基站非周期性的配置时，该时间窗口配置信息包括下列参数的一个或者多个：时间窗口的大小和时间窗口起始位置，时间窗口的大小即为目标子帧组中所包含的目标子帧的个数。如图4所示，为本申请实施例提供的一种可能的非周期性的时间窗口示意图，每个白色框代表一个目标子帧，即该时间窗口中包括3个目标子帧，可以理解的是，由于时间窗口中的子帧为连续的，故时间窗口的大小和起始位置为已知时，可以确定该时间窗口。
302、基站对时间窗口配置信息进行加扰。
本申请实施例中，步骤302与图1所示的步骤102类似，具体此处不再赘述。
303、基站发送第二消息到终端。
本申请实施例中，基站通过步骤303发送第二消息到终端的方式与图1所示的步骤103基站发送第一消息到终端的方式类似，具体此处不再赘述，另外，与第一消息类似，第二消息也可为半静态调度指令，例如RRC信令或者MAC CE信令，具体此处不做限定，且该第二消息至少携带时间窗口配置信息中的时间窗口的大小。
304、基站发送第二动态信息到终端。
本申请实施例中，基站通过步骤304发送第二动态信息到终端的方式与图1所示的步骤104基站发送第一动态信息到终端的方式类似，具体此处不再赘述。另外，基站还向终端发送第二动态信息，该第二动态信息用于指示时间窗口起始位置。具体地，基站通过物理下行通道(physical downlink control channel，PDCCH)的动态信令发送给终端，即该第二动态信息可以为PDCCH上承载的DCI。
305、基站向终端发送至少两个连续子帧中相同的指示信息。
306、终端确定发送上行数据的位置。
本申请实施例中，步骤305至步骤306与图1所示的步骤105至106类似，具体此处不再赘述。
本申请实施例中，基站非周期性的配置时间窗口配置信息，降低了基站和终端的功耗和实现复杂度，也增加了本申请实施例的可实现方式。
需要说明的是，图1所示的实施例中，基站配置周期性的时间窗口配置信息来指示目标子帧组，图3所示的实施例中，基站配置非周期性的时间窗口配置信息来指示目标子帧组，本申请中，基站还可以通过时间窗口配置信息直接告知终端目标子帧组，例如，时间窗口配置信息可以包括：目标子帧组内的子帧帧号，如子帧1、子帧2和子帧3；或，目标子帧组内的起始子帧的帧号和结束子帧的帧号，如起始子帧为子帧5，结束子帧为子帧8；或，目标子帧组内的起始子帧的帧号和子帧跨度，如起始子帧为子帧5，子帧跨度为3个子帧，故时间窗口配置信息的内容具体此处不做限定。
