Description

无线通信方法、基站和终端 技术领域
本发明实施例涉及通信技术，尤其涉及一种无线通信方法、基站和终端。
背景技术
长期演进的授权辅助接入(Licensed-Assisted Access Using Long Term Evolution，简称LAA-LTE)具体指在将LTE系统部署于授权载波中运营的基础之上，引入非授权载波分担授权载波中的数据流量。非授权载波具有低费用、准入要求低以及资源共享等优点，具体的，将非授权载波应用于LTE中的具体实现方式包括基于载波聚合(Carrier Aggregation，简称CA)和双联接(Dual Connectivity，简称DC)的方式，当以载波聚合方式进行运营时，授权载波作为主载波(Pcell)，非授权载波作为辅载波(Scell)，其中，上行和下行均可以在同一个非授权载波上传输，具体可以采用时分复用(Time Division Multiplexing，简称TDM)的形式进行传输。
对于基站采用非授权载波进行上行和下行数据传输，首先，基站进行CCA(clear channel assessment)抢占信道，检测到信道空闲时，发送下行数据，下行数据发送结束后，进行上下行转换以及终端发送上行数据前进行的CCA，之后，终端发送上行数据。在上述过程中，基站调度用于发送上行数据的上行子帧可以采用自调度的方式，具体的，在非授权载波中的下行子帧中发送下行控制信息，该下行控制信息中包括调度上行子帧的上行调度指示，其中，具体采用一个下行子帧中发送一个下行控制信息，该下行控制信息对应调度一个下行子帧和一个上行子帧，然而，在数据传输过程中，如果需要调度的上行子帧个数多于下行子帧个数，那么自调度的方式则不能满足需求。为了进一步满足各种调度需求，对于调度上行子帧个数多于下行子帧时，可以非授权载波采用自调度调度下行子帧，而对于上行子帧可以利用授权载波进行跨载波调度，或者，非授权载波采用自调 度调度下行子帧和部分上行子帧，对于剩余上行子帧利用授权载波进行跨载波调度。
然而，采用上述方式进行上行子帧的调度过程中，一个上行子帧被调度需要一个下行控制信息中的上行调度指示信息，通常基站需要调度多个上行子帧，从而由于需要多个下行子帧中的上行调度指示信息，会造成基站与终端之间的信令开销大的问题。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例公开了一种无线通信方法，具体涉及一种上行调度方法，本发明实施例可以应用于无线通信系统中，例如LAA-LTE系统等。图1为终端与基站之间进行通信的示意图，如图1所示，基站与终端之间可以通过授权载波和非授权载波进行数据交互，其中，授权载波和非授权载波均可以进行上行和下行数据发送，并且授权载波和非授权载波均可以进行控制信令的发送以及业务数据的发送。非授权载波的频段未被相关部门授权给某种系统占用，其具有免费、共享特性，例如，5GHZ的频段，该频段的载波主要用于WIFI、蓝牙、医疗系统的信号的传输。在LTE系统中使用非授权载波(即LAA-LTE)，可以有效提升LTE系统的数据吞吐量。本发明实施例用于减少LAA-LTE系统中上行子帧调度过程中的信令开销。
图2为本发明无线通信方法实施例一的信令交互图，图3为本发明的一种上行子帧调度方式示意图，图4为本发明的另一种上行子帧调度方式示意图，图5为本发明的又一种上行子帧调度方式示意图，图6为本发明的再一种上行子帧调度方式示意图，如图2所示，本实施例的方法可以包括：
步骤101、基站向终端发送下行控制信息，所述下行控制信息包括上行调度指示信息。
具体的，基站可以根据数据调度需求生成下行控制信息，该下行控制信息中可以包括下行调度指示信息和上行调度指示信息，即通过该下行控制信息同时将上下行调度指示告知终端，使得终端在相应的下行子帧上接 收基站发送的下行数据，在相应的上行子帧上向基站发送上行数据。
步骤102、所述终端根据所述上行调度指示信息在至少一个非授权载波的多个上行子帧上发送上行数据。
具体的，由于下行控制信息包括用于调度一个或多个非授权载波的多个上行子帧的上行调度指示信息，终端解析获取上行调度指示信息，根据该上行调度指示信息在相应载波的上行子帧上发送上行数据。
上述步骤101的一种可实现方式，基站具体可以通过非授权载波向终端发送所述下行控制信息，该下行控制信息用于调度非授权载波的多个上行子帧，具体可以参见图3，如图3所示，非授权载波(SCell)在不同子帧进行下行传输和上行传输，即基站利用非授权载波发送控制信息，以调度该非授权载波的下行子帧和上行子帧，即自调度的方式。如图3所示，基站在该非授权载波上首先进行CCA，之后通过该非授权载波进行下行控制信息发送，实现对下行子帧和上行子帧的调度，具体的，基站在非授权载波的子帧N上发送一个下行控制信息，该下行控制信息调度子帧N发送下行数据，并且调度子帧N+4进行上行传输，基站在非授权载波的子帧N+1上发送另一下行控制信息，该下行控制信息调度子帧N+1发送下行数据，并且调度子帧N+5进行上行传输，基站在非授权载波的子帧N+2上发送另一个下行控制信息，与子帧N和子帧N+1的下行控制信息不同，子帧N+2的下行控制信息调度子帧N+2发送下行数据，并且调度子帧N+6、子帧N+7和子帧N+8进行上行传输，需要说明的是，被调度的三个子帧也可以不连续，被调度的子帧的位置可以根据需求进行灵活配置。
上述步骤101的另一种可实现方式，基站具体可以通过授权载波向终端发送所述下行控制信息，该下行控制信息用于调度非授权载波的多个上行子帧，具体可以参见图4，如图4所示，非授权载波(SCell)在不同子帧进行下行传输和上行传输，具体的，基站在该非授权载波上首先进行CCA，之后通过该非授权载波进行下行控制信息发送，该非授权载波发送的下行控制信息仅用于调度该非授权载波的子帧进行下行传输，如图4所示，通过非授权载波的子帧N发送下行控制信息，该子帧N的下行控制信息仅用于调度子帧N进行下行传输，通过非授权载波的子帧N+1调度子帧N+1进行下行传输，而对于上行子帧的调度，可以通过授权载波 (PCell)在子帧N-1发送下行控制信息，该子帧N-1的下行控制信息用于调度非授权载波的子帧N+3、子帧N+4、子帧N+5以及子帧N+6进行上行传输，即采用跨载波调度的方式进行上行子帧调度。需要说明的是，图4仅为一种示意性举例说明，具体授权载波的哪个子帧进行跨载波的上行子帧调度，以及具体调度非授权载波的哪几个子帧(个数和位置)进行上行传输均可以根据实际需求进行灵活配置。
上述步骤101的又一种可实现方式，基站具体可以通过授权载波向终端发送所述下行控制信息，该下行控制信息用于调度非授权载波的部分上行子帧，具体可以参见图5，如图5所示，非授权载波(SCell)在不同子帧进行下行传输和上行传输，具体的，基站在该非授权载波上首先进行CCA，之后通过该非授权载波进行下行控制信息发送，该非授权载波发送的下行控制信息用于调度该非授权载波的子帧进行下行传输，并且调度该非授权载波的子帧进行上行传输，如图5所示，通过非授权载波的子帧N-1发送下行控制信息，该子帧N-1的下行控制信息用于调度子帧N-1进行下行传输和子帧N+3进行上行传输，通过非授权载波的子帧N调度子帧N进行下行传输和子帧N+4进行上行传输，直至，通过非授权载波的子帧N+2调度子帧N+2进行下行传输和子帧N+6进行上行传输，这样，下行子帧调度完成，但是还存在需要被调度的非授权载波的子帧N+7和子帧N+8，那么，基站可以通过授权载波(PCell)的子帧N+3发送下行控制信息，以调度非授权载波(SCell)的子帧N+7和子帧N+8进行上行传输。需要说明的是，图5仅为一种示意性举例说明，具体授权载波的哪个子帧进行跨载波的上行子帧调度，以及具体调度非授权载波的哪几个子帧(个数和位置)进行上行传输均可以根据实际需求进行灵活配置。
上述步骤101的又一种可实现方式，基站具体可以通过授权载波向终端发送所述下行控制信息，该下行控制信息用于调度不同的非授权载波的上行子帧，具体可以参见图6，如图6所示，非授权载波(SCell)在不同子帧进行下行传输和上行传输，具体的，基站在该非授权载波上首先进行CCA，之后通过该非授权载波进行下行控制信息发送，该非授权载波发送的下行控制信息仅用于调度该非授权载波的子帧进行下行传输，如图6所示，通过非授权载波1(SCell 1)和非授权载波2(SCell 2)的子帧N分 别发送下行控制信息，两个非授权载波的子帧N的下行控制信息用于调度自身的子帧N进行下行传输，通过非授权载波1和非授权载波2的子帧N+1调度子帧的子帧N+1进行下行传输，通过非授权载波1和非授权载波2的子帧N+2调度自身的子帧N+2进行下行传输，这样，下行子帧调度完成，但是还存在需要被调度的非授权载波1和非授权载波2的子帧N+4以及非授载波1的子帧N+5，那么，基站可以通过授权载波(PCell)的子帧N发送下行控制信息，以调度非授权载波1和非授权载波2的子帧N+4以及非授载波1的子帧N+5进行上行传输。需要说明的是，图6仅为一种示意性举例说明，具体授权载波的哪个子帧进行跨载波的上行子帧调度，以及具体调度哪个非授权载波的哪几个子帧(个数和位置)进行上行传输均可以根据实际需求进行灵活配置。
其中，发送上述上行调度指示信息的下行子帧的索引与被调度的上行子帧的索引之差为可变值，且为整数，举例而言，如图6所示，授权载波的子帧N发送上行调度指示信息与被调度的非授权载波的子帧N+4间隔为4，授权载波的子帧N发送上行调度指示信息与被调度的非授权载波的子帧N+5间隔为5。
具体的，被调度的上行子帧与发送下行控制信息的下行子帧在相同的最大信道占用时间(MCOT)内。
本实施例，通过基站向终端发送下行控制信息，该下行控制信息包括上行调度指示信息，所述上行调度指示信息用于指示终端在至少一个非授权载波的多个上行子帧上发送上行数据，从而使得终端根据该上行调度指示信息在相应的一个或多个非授权载波的多个上行子帧上发送上行数据，进而实现一个下行控制信息中的上行调度指示信息调度多个上行子帧进行上行传输，在提升数据传输数据量的同时有效减少调度信令开销。
下面采用几个具体的实施例，对上述方法实施例的技术方案中的上行调度指示信息进行详细说明。
图7为本发明的一种上行调度指示信息的结构示意图，如图7所示，本实施例的上行调度指示信息可以包括：起始上行子帧位置信息和连续的上行子帧个数，具体的，图7所示的上行调度指示信息具体应用于连续的子帧调度。举例而言，如图3所示的调度场景，即非授权载波的子帧N+2 调度子帧N+6、子帧N+7和子帧N+8进行上行传输，那么就可以采用图7所示实施例的上行调度指示信息的结构，该上行调度指示信息仅需要携带起始上行子帧位置信息(子帧N+6)和连续的行子帧个数(3)，需要说明的是，图7所示的上行调度指示信息可以缺省载波的索引，那么终端解析到未携带载波的索引，则可以认为发送上行数据的载波与接收到上行调度指示信息的载波为相同载波。其中，起始上行子帧位置信息具体可以为起始上行子帧索引(start frame index)。
图8为本发明的另一种上行调度指示信息的结构示意图，如图8所示，本实施例的上行调度指示信息在图7所示结构的基础上，还可以包括载波索引，终端根据该载波索引可以确定进行上行传输的子帧对应的载波，进而在相应的子帧上进行上行数据传输。举例而言，如图4所示的调度场景，授权载波(PCell)在子帧N+1发送上行调度指示信息，该子帧N+1的上行调度指示信息用于调度非授权载波的子帧N+3、子帧N+4、子帧N+5以及子帧N+6进行上行传输，那么就可以采用图8所示实施例的上行调度指示信息的结构，该上行调度指示信息需要携带载波索引(PCell的索引)、起始上行子帧位置信息(子帧N+3)和连续的行子帧个数(4)。
图9为本发明的又一种上行调度指示信息的结构示意图，图7和图8所示的上行调度指示信息用于调度连续的子帧，对于非连续的子帧可以采用图9所示的上行调度指示信息的结构，如图9所示，本实施例的上行调度指示信息可以包括每一个连续部分的起始子帧位置信息和连续的子帧个数，举例而言，非授权载波的子帧N调度子帧N+5、子帧N+6以及子帧N+8，那么非授权载波的子帧N的上行调度指示信息可以包括第一连续部分的起始上行子帧位置信息(N+5)和连续的子帧个数(2)、第二连续分布的起始上行子帧位置信息(N+8)和连续的子帧个数(0)。对于更多的子帧调度可以采用如上所述的方式，此处不再一一赘述。
图10为本发明的再一种上行调度指示信息的结构示意图，与图9所示的上行调度指示信息的结构不同，本实施例的上行调度指示信息用于指示具有固定间隔起始位置的子帧调度，如图10所示，本实施例的上行调度指示信息可以包括起始上行子帧位置信息、上行子帧个数、起始上行子帧周期(start subframe peoridic)以及起始上行子帧偏移值(start subframe  offset)。举例而言，非授权载波的子帧N调度子帧N+5、子帧N+6、子帧N+8和子帧N+9，那么非授权载波的子帧N的上行调度指示信息可以包括起始上行子帧位置信息(N+4)、上行子帧个数(2)、起始上行子帧周期(3)和起始上行子帧偏移值(1)。对于更多的子帧调度可以采用如上所述的方式，此处不再一一赘述。
需要说明的是，当需要调度不同载波的非连续的子帧进行上行传输时，在图9和图10所示的上行调度指示信息基础上，还可以包括载波索引，以指示在相应的载波的子帧上进行上行传输。
图11A为本发明的一种RRC信令的结构示意图，图11B为本发明的再一种上行调度指示信息的结构示意图，与图9所示的上行调度指示信息的结构不同，本实施例的上行调度指示信息仅用于携带部分上行调度指示参数(相对动态的参数)，而剩余部分的上行调度指示参数(相对静态的参数)通过RRC信令发送个终端，具体的可以如图11A和图11B所示，通过RRC信令和上行调度指示信息相结合的方式发送上行调度指示参数，以使得终端可以根据该RRC信令和上行调度指示信息获知可以发送上行数据的子帧，具体的，RRC信令可以包括连续的上行子帧个数和起始上行子帧周期，相应的，上行调度指示信息可以包括起始上行子帧位置信息和起始上行子帧偏移值。进一步的，RRC信令还可以包括MCS(Modulation and Coding Scheme，调制与编码策略)等参数信息，上行调度指示信息还可以包括资源分配信息、TPC(Transmission Power Control，传输功率控制)等参数信息。
图12为本发明基站实施例一的结构示意图，如图12所示，本实施例的装置可以包括：发送模块11和处理模块12，其中，发送模块11用于向终端发送处理模块12生成的下行控制信息，所述下行控制信息包括上行调度指示信息，所述上行调度指示信息用于指示终端在至少一个非授权载波的多个上行子帧上发送上行数据。
