具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。针对本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、免授权频谱上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、免授权频谱上的NR(NR-based access to unlicensed spectrum，NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，以及车辆间(Vehicle to Vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。
可选地，本申请实施例中的通信系统可以应用于载波聚合(Carrier Aggregation，CA)场景，也可以应用于双连接(Dual Connectivity，DC)场景，还可以应用于独立(Standalone，SA)布网场景。
本申请实施例对应用的频谱并不限定。例如，本申请实施例可以应用于授权频谱，也可以应用于免授权频谱。
示例性的，本申请实施例应用的通信系统100如图1所示。该通信系统100可以包括网络设备110，网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。
图1示例性地示出了一个网络设备和两个终端设备，可选地，该通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。
可选地，该通信系统100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例对此不作限定。
应理解，本申请实施例中网络/系统中具有通信功能的设备可称为通信设备。以图1示出的通信系统100为例，通信设备可包括具有通信功能的网络设备110和终端设备120，网络设备110和终端设备120可以为上文所述的具体设备，此处不再赘述；通信设备还 可包括通信系统100中的其他设备，例如网络控制器、移动管理实体等其他网络实体，本申请实施例中对此不做限定。
应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
本申请实施例结合终端设备和网络设备描述了各个实施例，其中：终端设备也可以称为用户设备(User Equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置等。终端设备可以是WLAN中的站点(STAION，ST)，可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及下一代通信系统，例如，NR网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)网络中的终端设备等。
作为示例而非限定，在本申请实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
网络设备可以是用于与移动设备通信的设备，网络设备可以是WLAN中的接入点(Access Point，AP)，GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB，NB)，还可以是LTE中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者中继站或接入点，或者车载设备、可穿戴设备以及NR网络中的网络设备或者基站(gNB)或者未来演进的PLMN网络中的网络设备等。
在本申请实施例中，网络设备为小区提供服务，终端设备通过该小区使用的传输资源(例如，频域资源，或者说，频谱资源)与网络设备进行通信，该小区可以是网络设备(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(Small cell)对应的基站，这里的小小区可以包括：城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。
NR帧结构以时隙为基本颗粒度，每个时隙中的符号分为三类：下行符号，上行符号和灵活符号。NR帧结构配置采用半静态无线资源控制配置和动态下行控制信息配置结合的方式进行灵活配置。NR中RRC高层配置和DCI物理层配置均可以实现对帧结构的修改。当不同配置对帧结构进行修改时，一旦发生冲突，就需要确定各种配置相互覆盖的原则。
NR中半静态上下行配置，半静态测量配置，动态SFI及DCI的相互覆盖规则如下：
半静态上下行配置的上行及下行不能修改，半静态上下行配置的灵活符号可以由半静态测量配置，动态SFI及DCI配置更改。
半静态测量配置中的上行及下行配置可以被动态SFI及DCI配置更改，一旦更改发生，半静态测量相关的行为将被终止。
DCI配置的数据发送不能喝SFI配置的上行和下行冲突，但是可以对SFI配置中的灵活部分进行修改。
为了提高物理下行共享信道(Physical Downlink Shared Channel，PDSCH)的传输可靠性，NR引入了PDSCH的重复传输，即携带相同数据的PDSCH通过不同的时隙/传输接收点(Transmission Reception Point，TRP)/冗余版本等多次传输，从而获得分集增益，降低误检概率。具体的，所述重复传输可以在多个时隙进行(如图3)，也可以在多个TRP上进行。对于多时隙的重复，一个DCI可以调度多个携带相同数据的PDSCH在连续的多个时隙上传输，采用相同的频域资源。对于多TRP的重复，携带相同数据的PDSCH在不同TRP上分别传输，可以采用不同的波束(此时需要在一个DCI中指示多个TCI状态，每个传输配置指示(Transmission Configuration Indicator，TCI)状态用于一次重复传输)。多TRP的重复也可以和多时隙的方式结合，采用连续的时隙来传输，在不同的时隙采用不同的TRP进行传输。
在一个slot中，可能存在有上行符号、下行符号及灵活符号。其中，上行符号、下行符号及灵活符号可以由半静态的高层信令指示，对于半静态指示的灵活符号(flexible symbol)，还可以通过动态DCI来指示灵活符号为上行符号或下行符号或灵活符号。对于高可靠低时延通信(Ultra-Reliable and Low Latency Communication，URLLC)的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)传输，可能需要跨越多个symbol或者多个slot来进行传输，当终端在接收动态SFI时，可能在URLLC的PUSCH传输的任一位置，如果终端设备和网络设备对动态SFI的生效时间理解不一致，将会导致PUSCH无法在正确的时间上进行传输或接收，从而无法达到URLLC的高可靠低时延的性能要求。
以下详细阐述本申请针对上述技术问题而设计的基于动态SFI确定多次重复传输中灵活符号传输方向的方案。
图3是根据本申请实施例的无线通信方法200的示意性流程图，如图3所示，该方法200可以包括如下内容中的部分或全部：
S210，终端设备在第一时域位置上监听第一SFI；
S220，该终端设备根据该第一SFI的监听结果和该第一SFI的生效时刻与多次重复传输中的第一传输的起始时刻的位置关系，确定第一时域资源中的灵活符号传输方向，其中，该多次重复传输中的部分或者全部位于该第一时域资源中的灵活符号上。

需要说明的是，在执行上述步骤S220之后，该第一时域资源中的灵活符号传输方向可以是上行，也可以是下行，当然在某些情况下，该第一时域资源中的灵活符号还可能依然是灵活符号。
可选地，在本申请实施例中，该第一传输为以下中的一种：

可选地，在上述示例3至示例5中，该第二SFI的生效时间可以是网络设备配置的， 或者，该第二SFI的生效时间是预配置的。
可选地，在本申请实施例中，对于某一个SFI，由于网络设备无法确定终端设备是否正确接收这一SFI，因此，网络设备需要按照正确接收这一SFI和未正确接收这一SFI两种假设在可能的时域资源进行接收。
以下以具体实施例详述本申请无线通信方法200。
可选地，作为实施例1，如图4所示，终端设备在slot n-2k+m接收到动态SFI 1，以及在slot n-k接收到动态SFI 2。其中，动态SFI 1用于指示slot n-2k+m之后的一段时间内半静态(semi-static)配置为灵活符号的传输方向，动态SFI 2用于指示slot n-k之后的一段时间内半静态配置为灵活符号的传输方向。动态SFI 1的生效时间为slot n-2k+m+t到slot n的第一个符号，动态SFI 2的生效时间为slot n的第二个符号到后面某一个时间。其中动态SFI的周期为k-m。
在实施例1中，终端设备接收网络设备配置的重复传输，其中重复传输的重复次数为2次，2次一共占用的时域资源从slot n的第一个符号开始到slot n的第10个符号结束。
由于动态SFI 2的生效时刻晚于重复传输的第一次传输的起始位置，所以这次重复传输的所有传输均按照上一个SFI(即动态SFI 1)的指示来确定占用的时域资源中为灵活符号的传输方向。在实施例1中，对于符号3-符号9，都按照动态SFI 1的指示来确定，也就是这2次重复传输中，符号3-符号9的传输方向为U U U D D D D，其中“U”代表上行，“D”代表下行，“F”代表灵活符号。
可选地，作为实施例2，如图5所示，终端设备在slot n-2k+m接收到动态SFI 1，以及在slot n-k接收到动态SFI 2。其中，动态SFI 1用于指示slot n-2k+m之后的一段时间内semi-static配置为灵活符号的传输方向，动态SFI 2用于指示slot n-k之后的一段时间内半静态配置为灵活符号的传输方向。动态SFI 1的生效时间为slot n-2k+m+t到slot n的第一个符号，动态SFI 2的生效时间为slot n的第二个符号到后面某一个时间。其中动态SFI的周期为k-m。
在实施例2中，终端设备接收网络设备配置的重复传输，其中重复传输的重复次数为2次，2次一共占用的时域资源从slot n的第一个符号开始到slot n的第10个符号结束。
由于动态SFI 2的生效时刻晚于重复传输的第一次传输的起始位置但早于重复传输的第二个传输的起始位置，所以这2次重复传输的第一次传输按照动态SFI 1的指示来确定占用的时域资源中为灵活符号的传输方向，第二次传输均按照动态SFI 2的指示来确定占用的时域资源中为灵活符号的传输方向。在实施例2中，对于符号3-符号9，符号3-符号5按照动态SFI 1的指示来确定，符号6-符号9按照动态SFI 2的指示来确定。也就是这2次重复传输中，符号3-符号9的传输方向为U U U U U U U，其中“U”代表上行，“D”代表下行，“F”代表灵活符号。
可选地，作为实施例3，如图6所示，终端设备在slot n-2k+m接收到动态SFI 1，以及在slot n-k监听动态SFI 2，但并未正确接收动态SFI 2。其中，动态SFI 1用于指示slot n-2k+m之后的一段时间内semi-static配置为灵活符号的传输方向。动态SFI 1的生效时间为slot n-2k+m+t到slot n的第一个符号，动态SFI 2的生效时间为slot n的第二个符号到后面某一个时间。其中动态SFI的周期为k-m。
在实施例3中，终端设备接收网络设备配置的重复传输，其中重复传输的重复次数为2次，2次一共占用的时域资源从slot n的第一个符号开始到slot n的第10个符号结束。
由于动态SFI 2的生效时刻晚于重复传输的第一次传输的起始位置但早于重复传输的第二个传输的起始位置，所以这次重复传输的第一次传输按照动态SFI 1的指示来确定占用的时域资源中为灵活符号的传输方向，第二次传输按照动态SFI 2的指示来确定占用的时域资源中为灵活符号的传输方向。在实施例3中，对于符号3-符号9，符号3-符号5按照动态SFI 1的指示来确定，但由于第二次传输需要应用的动态SFI 2并没有正确接收，因此按照没有正确接收动态SFI 2来对符号6-符号9的数据传输的处理方式(即符号6- 符号9还是灵活符号)。也就是这2次重复传输中，符号3-符号9的传输方向为U U U F F F F，其中“U”代表上行，“F”代表灵活符号。
因此，在本申请实施例中，终端设备根据第一SFI的监听结果和第一SFI的生效时刻与多次重复传输中的第一传输的起始时刻的位置关系，确定第一时域资源中的灵活符号传输方向，从而可以确定多次重复传输的每次传输上的灵活符号的传输方向，进而确定每次传输的可用符号，确保网络设备和终端设备对每次传输的可用符号的理解一致。
