Description

一种资源分配方法、终端以及基站
本申请要求2017年11月30日递交中国专利局、申请号为201711240390.X的中国专利申请，以及2018年3月30日递交中国专利局、申请号为201810289231.7的中国专利申请的优先权，其全文通过引用包含于本申请中。
技术领域
本发明涉及通信技术领域，尤其涉及一种资源分配方法、终端以及基站。
背景技术
无线通信系统使用的频谱，分为两类，授权频谱(licensed spectrum)和非授权频谱(unlicensed spectrum)。对于商用的移动通信系统，运营商需要拍卖授权频谱，获得授权后，可以使用相应的频谱开展移动通信的运营活动。非授权频谱不需要拍卖，任何人都可以合法的使用这些频段。在3GPP RAN#75次会议上，“enhancements to LTE operation in unlicensed spectrum”立项成功，其中主要的研究内容包括Specify support for multiple starting and ending positions in a subframe for UL and DL on SCell with Frame structure type 3，即针对授权辅助接入(licensed-assisted access，LAA)上下行的开始结束位置进行研究。在RAN1 90次会议中，有关自动上行传输达成了如下的agreement：The support of autonomous uplink access with frame structure type 3is specified within the scope of Release 15FeLAA WI.即：在REL.15开始对子帧类型3的自动上行传输开始进行研究。
在现有通用移动通信技术的长期演进(long term evolution，LTE)增强型授权辅助接入(eLAA)中，上行资源都是基站通过下行控制信息(Downlink Control Information，DCI)动态通知的，而对于eLAA自动上行传输(autonomous uplink，AUL)而言，上行资源是基站通过高层信令半静态分配的，当有紧急或者重要业务时(调度的上行传输(scheduled uplink，SUL)的优先级高于AUL)，基站会调度终端(UE)在AUL的资源上发送SUL数据，从而可能导致调度的资源与AUL资源发生碰撞。

具体实施方式
下面将结合附图，对本发明实施例中的技术方案进行描述。显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。
图1为本发明实施例提供的通信系统架构示意图。该系统包括：终端和基站。终端可以和基站之间建立通信连接。
本申请所涉及到的基站(base station，BS)是一种部署在无线接入网中用以为通信节点提供无线通信功能的装置。所述基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在LTE网络中，称为演进的节点B(evolved NodeB简称：eNB或者eNodeB),在第三代3G网络中，称为节点B(Node B)等等。为方便描述，本申请中，上述为终端提供无线通信功能的装置统称为基站或BS。
本申请各实施例中的终端包括但不限于：手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端设备、增强现实(Augmented Reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。
下面通过图2和图9对本发明实施例提供的分配资源方法的处理过程进行详细描述。
图2为本发明实施例提供了一种分配资源方法的流程图。如图2所示，该资源分配方法可以包括以下步骤：
步骤S201：基站向终端发送第一消息，第一消息用于指示终端进行AUL的偏移量，其中，偏移量的值大于或等于1个正交频分复用技术(orthogonal frequency division multiplexing，OFDM)符号，小于或等于5个OFDM符号。
在一个可能的实施例中，基站发送第一消息的方法可包括但不限于：基站通过无线资源控制(radio resource control，RRC)消息、下行控制信息(downlink control information， DCI)或者广播消息发送第一消息。
步骤S202：终端接收基站发送的第一消息。
步骤S203：终端根据SUL的起始位置和偏移量确定进行自动上行传输AUL的位置。
在一个可能的实施例中，第一消息可包括一个或者多个偏移量。
具体地，当第一消息包括一个偏移量时，终端根据该偏移量和SUL的起始位置确定进行自动上行传输AUL的位置。或者，当第一消息包括多个偏移量时，终端从多个偏移量中选择一个偏移量，并根据该偏移量和SUL的起始位置确定进行自动上行传输AUL的位置。从多个偏移量中选择一个偏移量的方式可以是随机选取，也可根据规律进行选取，在此不赘述。
需要说明的是，多个偏移量可以是相同的也可以是不同的。
假设，上行传输采用时分复用(TDM)模式，此时的多个偏移量不同或相同的。
具体地，不同UE占用不同时间段的资源，SUL上行传输的起始位置是固定的，例如，符号0开始。那么为了避免AUL与SUL发生资源碰撞，保证SUL数据的传输，UE1和UE2先听后发(listen before talk，LBT)，在发送保证SUL数据之后，UE1和UE2自主发送AUL，其中，AUL在SUL数据发送起始位置的基础上可以随机选择一些offset值，该offset值大于或等于1个OFDM符号，小于或等于5个OFDM符号，并在该offset期间进行退避，从而避免和SUL传输发生碰撞。
需要说明的是，一个子帧时间长度为1ms，包含2个时隙，一个时隙中有7个OFDM符号，那么在一个子帧有14个OFDM符号，在本发明实施例中，SUL的起始位置可以为符号0，也可以为符号7，为了避免AUL传输数据的位置，offset的取值不能小于或等于0OFDM符号，也不能大于6OFDM符号。故offset值可以大于1个OFDM符号，小于或等于5个OFDM。
在一些实施例中，UE需要在非授权频谱上发送数据时，首先要对信道进行检测。如图3所示，UE1和UE2在该非授权频谱上发送数据，检测到信道繁忙(channel busy)，则需要进行退避，当退避结束后接入信道，因为SUL上行传输的起始位置是固定的，所以UE1和UE2进行AUL传输时，在SUL起始位置的基础上加上offset值后确定AUL的起始发送位置并从该位置开始发送数据，从而可以避免与SUL传输发生碰撞。
假设，上行传输采用频分复用(FDM)模式，此时多个偏移量是相同的。
具体地，如图4所示，在频域上采用交织(interlacing)结构，不同的UE可以占用一个或者多个interlacing，例如附图4中的UE1和UE2，而因为该时频资源都已经预配置给AUL资源，且多个AUL UE同时在该资源上传输，因此为了不与SUL资源发送碰撞，并保证AUL UE可以同时传输，从而配置相同的offset值给不同的AUL UE。
在一个可能的实施例中，基站可以通过以下几种方式配置多个偏移量。
在TDM模式下，基站可以通过高层信令，比如RRC信令，半静态的配置一组offset值，当UE进行AUL传输时，可以在一组offset值中进行随机的选择，从而避免和UE传输SUL发生碰撞。一组offset值可以设置在一个阈值范围内，在该范围内可以从一组offset值中选择一个offset值传输AUL。其中，半静态是指基站在一定周期内配置一组offset值，并在该周期内该一组offset值是不变的。
在FDM模式下，基站可通过高层信令或者广播信令通知UE，也可以在DCI的公共搜 索空间(common search space)中通知给UE，从而所有的AUL UE可以采用相同的offset值，避免与UE传输SUL发生碰撞。
Offset可以通过几bit进行表示，例如，2bit，该2bit信息如下表所示：
index Offset value
00 Offset 0
01 Offset 1
10 Offset 2
11 Offset 3
上表中，根据offset值，确定传输AUL的位置；例如，当offset值为0时，确定在00位置处传输AUL。
本发明实施例提供了一种分配资源方法，通过基站发送的第一消息包括的偏移量，以及SUL的起始位置，确定进行AUL的起始位置，从而有效避免SUL与AUL资源发生碰撞，提高信道利用率。
上述实施例描述的方法，可使终端确定进行AUL的起始位置。相应地，本发明实施例提供一种终端，用以实现前述实施例中提供的分配资源方法，如图5所示，该终端可包括：接收单元510、处理单元520和发送单元530。
接收单元510，用于接收基站发送的第一消息，第一消息用于指示终端进行自动上行传输AUL的偏移量，偏移量的值大于或等于1个OFDM符号，小于或等于5个OFDM符号；处理单元520，用于根据SUL的起始位置和偏移量确定进行自动上行传输AUL的位置；发送单元530，用于根据AUL数据传输的位置和SUL数据传输的位置分别传输相应的数据。
在本申请的实施例中，通过上述示例，本发明实施例提供的终端，通过基站发送的第一消息，该第一消息用于指示终端进行自动上行传输AUL的偏移量，进一步，通过SUL的起始位置和偏移量确定进行自动上行传输AUL的位置，使得SUL数据传输的位置和AUL数据传输的位置不重叠，从而有效避免SUL与AUL资源发生碰撞，提高信道利用率。
在一个可能的实施例中，第一消息包括一个或者多个偏移量。
在一个可能的实施例中，处理单元620，还用于：当第一消息包括多个偏移量时，从所述多个偏移量中选择一个偏移量，并根据选择的偏移量和SUL的起始位置确定进行自动上行传输AUL的位置。
在一个可能的实施例中，第一消息包括高层信令、下行控制信息DCI或广播消息。
另外，本发明实施例提供的终端还可以采用的实现方式如下，用以实现前述本发明实施例中的分配资源方法，如图6所示，所述终端包括：接收器610、处理器620和发射器630。
在可选地实施例中，前述图5所述的实施例中的接收单元510可以由接收器610实现。具体地，第一消息为接收器610从基站接收的信息。具体地，第一消息用于指示终端进行自动上行传输AUL的偏移量，偏移量的值大于或等于1个OFDM符号，小于或等于5个OFDM符号。
处理单元520可以由处理器620实现。发送单元530可以由发射器630实现。所述终端还可包括存储器。
图6中各单元涉及的处理过程可参见前述图2所示的实施例，在此不做赘述。
图7为本发明实施例提供了一种基站的结构示意图。如图7所示，该终端可包括：发送单元710。
发送单元710，用于向终端发送第一消息，第一消息用于指示终端进行自动上行传输AUL的偏移量，偏移量的值大于或等于1个OFDM符号，小于或等于5个OFDM符号。
在一个可能的实施例中，第一消息包括一个或者多个偏移量。
在一个可能的实施例中，基站还包括：处理单元720；
处理单元720，用于通过无线资源控制RRC消息、下行控制信息DCI或者广播消息配置一个或多个偏移量。例如，处理单元720，可以通过高层信令，例如RRC信令，半静态配置一组偏移量。
在一个可能的实施例中，第一消息为高层信令、下行控制信息DCI或广播消息。
图8为本发明实施例提供了另一种基站的结构示意图。如图8所示，所述终端包括：接收器810和处理器820。
在可选地实施例中，前述图7所述的实施例中的发送单元710可以由发射器810实现。具体地，第一消息用于指示终端进行自动上行传输AUL的偏移量，偏移量大于或等于1个OFDM符号，小于或等于5个OFDM符号。
处理单元720可以由处理器820实现，具体地，处理器820，用于通过无线资源控制RRC消息、下行控制信息DCI或者广播消息配置一个或多个偏移量。所述基站还可包括存储器和发射器。
图8中各单元涉及的处理过程可参见前述图2所示的实施例，在此不做赘述。
图9为本发明实施例提供了另一种分配资源方法的流程图。如图9所示，该资源分配方法可以包括以下步骤：
步骤S901：基站向终端发送第二指示信息。
在一个可能的实施例中，基站发送第二消息的方法可包括但不限于：基站通过无线资源控制(radio resource control，RRC)消息、下行控制信息(downlink control information，DCI)或者广播消息发送第二消息。
步骤S902：终端接收基站发送的第二消息，第二消息用于指示基站是否在预配置的AUL资源上调度SUL传输，以便终端根据第二消息确定是否在预配置的AUL资源上进行AUL传输。
步骤S903：终端根据第二消息确定是否在预配置的AUL资源上进行AUL传输。
在一个可能的实施例中，第二消息若指示基站没有在预配置的AUL资源上调度SUL传输时，终端在预配置的资源上进行AUL传输。
在一个可能的实施例中，第二消息若指示基站在预配置的AUL资源上调度SUL传输，终端取消在在预配置的资源上进行AUL传输。
具体地，AUL UE在预配置的AUL资源上发送上行数据前，对common search space进行检测，若在common search space中检测到有关于上行数据时长(UL burst duration)的指示(该指示信息用于指示传输LAA SUL的时频资源的长度)，并且该SUL时频资源与预配置的AUL的时频资源重叠(overlap)时，AUL UE根据UL burst duration的相关指示，确定传输SUL上行数据的相关子帧时频资源，并放弃在相关子帧时频资源上进行AUL传输，从而避免与SUL资源发生碰撞，保证SUL数据的发送。
在一个可能的实施例中，可以通过在PDCCH的common search space中增加几比特信息，用于通知UE，基站是否调度了SUL在AUL的时频资源上发送。例如，基站通过在PDCCH的common search space中增加1比特信息，通知UE，基站是否调度了SUL在AUL的时频资源上发送，该1bit信息可以为common search space的字节之内或之外。
具体地，当基站调度了SUL在AUL资源上发送时，基站通过动态信令通知AUL UE，在相应的overlap的资源范围内不发送AUL数据；如果该1bit信息为0，则说明基站没有调度SUL资源在AUL时频资源上发送，此时AUL UE可以正常发送AUL数据；而若该1bit信息取1，则说明基站调度了SUL资源在AUL时频资源上发送，此时，AUL UE根据UL burst duration等信息确定overlapped子帧的时频资源，并取消在相应的子帧的时频资源上传输AUL数据，避免发送资源碰撞，并保证SUL的正常传输。
在一个可能的实施例中，第二消息为高层信令、下行控制信息DCI或广播消息。
