Description

电子设备、无线通信方法和计算机可读存储介质
本申请要求于2018年8月10日提交中国专利局、申请号为201810909120.1、发明名称为“电子设备、无线通信方法和计算机可读存储介质”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
本公开的实施例总体上涉及无线通信领域，具体地涉及电子设备、无线通信方法和计算机可读存储介质。更具体地，本公开涉及一种作为IAB(Integrated Access and Backhaul，综合接入和回传)无线通信系统中的父节点的电子设备、一种作为IAB无线通信系统中的子节点的电子设备、一种由IAB无线通信系统中的父节点执行的无线通信方法、一种由IAB无线通信系统中的子节点执行的无线通信方法以及一种计算机可读存储介质。
背景技术
IAB是NR(New Radio，新无线)通信系统中的一项重要技术。在IAB系统中，DN(Donor Node，供者节点)直接地或者通过一个或多个RN(Relay Node，中继节点)与其他节点(包括RN和UE(User Equipment，用户设备))相连。其中，RN与RN或者RN与DN之间的链路被称为BH(Backhaul，回传)链路，UE与RN或者UE与DN之间的链路被称为AC(Access，接入)链路。IAB系统的特点在于支持无线回传链路，即BH链路与AC链路均使用无线链路传输。进一步，为了提高覆盖性能指标等，不限制IAB系统中各个节点间的跳数。复杂的多跳结构为IAB系统的设计带来了很多挑战。
在IAB系统中，各个节点需要支持半双工的工作模式。也就是说，在同一个时间点，IAB系统中的节点只能接收数据，或者发送数据。换句话说，IAB系统中的节点不能同时接收数据和发送数据。考虑到IAB系统的这种半双工工作模式的限制，如何为IAB系统中的各个链路设计帧结构将是一个新的挑战。
在NR无线通信系统的物理层设计中，支持符号级的上下行配置。 也就是说，将帧结构中上下行配置的最小时间粒度缩小到一个符号。在一个时隙中，分为DL(Downlink，下行)符号，UL(Uplink，上行)符号和X符号(X符号可以被灵活配置为DL符号或UL符号)。现有的技术中已经定义了一些不同的时隙格式，时隙格式的设计为5G无线通信系统带来了很大的灵活性。例如，可以根据当前系统的数据流的特点，配置不同的上下行符号的配比。此外，NR无线通信系统还支持不同的子载波间隔，例如15KHZ、30KHZ、60KHZ、120KHZ、240KHZ等。对于具有不同的子载波间隔的系统，一个时隙的时长不同。不同的子载波间隔可以适应多样化的场景和业务流。5G无线通信系统的这些特点都为IAB系统中的帧结构设计带来了新的挑战。
因此，有必要提出一种技术方案，以结合5G无线通信系统的特点合理地为IAB系统设计帧结构。

具体实施方式
现在参考附图来更加充分地描述本公开的例子。以下描述实质上只是示例性的，而不旨在限制本公开、应用或用途。
提供了示例实施例，以便本公开将会变得详尽，并且将会向本领域技术人员充分地传达其范围。阐述了众多的特定细节如特定部件、装置和方法的例子，以提供对本公开的实施例的详尽理解。对于本领域技术人员而言将会明显的是，不需要使用特定的细节，示例实施例可以用许多不同的形式来实施，它们都不应当被解释为限制本公开的范围。在某些示例实施例中，没有详细地描述众所周知的过程、众所周知的结构和众所周知的技术。
图1是示出根据本公开的实施例的IAB系统的结构图。IAB无线通信系统可以包括多个节点，包括一个DN、一个或多个RN以及一个或多个UE。IAB系统中的所有节点都可以位于DN的覆盖范围内。进一步，DN可以直接地与RN或者UE通信，也可以通过一个或多个RN与RN或UE通信。此外，RN与DN、或者RN与RN之间的链路被称为BH链路，UE与DN、或者UE与RN之间的链路被称为AC链路。对于IAB系统中的任意一个链路，其靠近DN的一方可以被称为父节点，另一方可以被称为子节点。IAB系统中的除DN以外的每一个节点都具有唯一的父节点，而IAB系统中的一个节点可以不具有子节点、具有一个子节点或者具有多个子节点。也就是说，IAB系统中的父节点可以是DN或者RN，子节点可以是RN或者UE。
如图1所示，该IAB无线通信系统包括一个DN、三个RN(RN1、RN2和RN3)以及两个UE(UE1和UE2)。进一步，DN通过BH1链路与RN1直接通信；DN通过AC1链路与UE1直接通信；DN通过RN1经由BH1链路和BH2链路与RN2通信；DN通过RN1经由BH1链路和BH3链路与RN3通信；DN通过RN1经由BH1链路和AC2链路与UE2通信。在图1中所示的示例中，RN1和UE1可以被称为DN的子节点，而DN可以被称为RN1和UE1的父节点。类似地，RN2、RN3和UE2可以被称为RN1的子节点，而RN1可以被称为RN2、RN3和UE2的父节点。
如上所述，图1以示例性的方式说明了IAB系统的结构。这里，由于IAB系统的BH链路与AC链路均使用无线链路传输，因此IAB系统在本文中也被称为IAB无线通信系统。此外，由于IAB系统是5G NR通信系统中的技术，因此本公开所示的实施例适用于5G NR通信系统。
根据本公开的DN可以是网络侧设备，例如任何类型的TRP(Transmit and Receive Port，发送和接收端口)或基站设备，例如可以是eNB，也可以是gNB。
根据本公开的RN也可以是网络侧设备，例如TRP，或者具备基站设备的某些功能的网络侧设备，包括但不限于从UE和DN接收数据的功能、向UE和DN发送数据的功能，为UE配置某些参数的功能等。也就是说，RN可以是被布置在DN的覆盖范围内的具备基站设备的某些功能的网络侧设备。
根据本公开的UE可以是移动终端(诸如智能电话、平板个人计算机(PC)、笔记本式PC、便携式游戏终端、便携式/加密狗型移动路由器和数字摄像装置)或者车载终端(诸如汽车导航设备)。用户设备还可以被实现为执行机器对机器(M2M)通信的终端(也称为机器类型通信(MTC)终端)。此外，用户设备可以为安装在上述终端中的每个终端上的无线通信模块(诸如包括单个晶片的集成电路模块)。
图2是示出根据本公开的实施例的电子设备200的配置的示例的框图。这里的电子设备200可以作为IAB无线通信系统中任意一条链路的父节点，具体地可以是IAB无线通信系统中的DN或RN。
如图2所示，电子设备200可以包括周期配置单元210和格式配置单元220。
这里，电子设备200的各个单元都可以包括在处理电路中。需要说明的是，电子设备200既可以包括一个处理电路，也可以包括多个处理电路。进一步，处理电路可以包括各种分立的功能单元以执行各种不同的功能和/或操作。需要说明的是，这些功能单元可以是物理实体或逻辑实体，并且不同称谓的单元可能由同一个物理实体实现。
根据本公开的实施例，周期配置单元210可以根据电子设备200和电子设备的子节点之间的链路的子载波间隔为该链路配置时隙格式周期。这里，时隙格式周期包括预定数目的时隙。
根据本公开的实施例，周期配置单元210可以在子节点初始接入IAB系统时为电子设备200和子节点之间的链路配置时隙格式周期。在子节点初始接入的过程中，可以确定该子节点的父节点，并且父节点可以确定父节点与子节点之间的链路的子载波间隔并通过系统消息向子节点指示该子载波间隔，本公开对这个过程不做详细说明。此外，由于电子设备200 可能具有一个子节点，也可能具有多个子节点，因此周期配置单元210可以为与每个子节点之间的链路配置时隙格式周期。在本公开中，时隙格式周期可以表示用于配置时隙格式的周期。以时隙格式周期为2个时隙为例，以2个时隙为周期配置时隙格式。
根据本公开的实施例，格式配置单元220还可以为电子设备200与子节点之间的链路配置在一个时隙格式周期内的每个时隙的时隙格式。
也就是说，格式配置单元220可以以时隙格式周期为周期，从而为链路配置时隙格式。仍然以时隙格式周期为2个时隙为例，格式配置单元220可以在第1个时隙之前配置第1个时隙和第2个时隙的时隙格式、在第3个时隙之前配置第3个时隙和第4个时隙的时隙格式、在第5个时隙之前配置第5个时隙和第6个时隙的时隙格式等。当然，如果第3个时隙和第4个时隙的时隙格式分别与第1个时隙和第2个时隙的时隙格式相同，也可以省去配置第3个时隙和第4个时隙的时隙格式的过程。同样地，由于电子设备200可能具有一个子节点，也可能具有多个子节点，因此格式配置单元220可以为与每个子节点之间的链路配置时隙格式。
众所周知，在常规CP(Cyclic Prefix，循环前缀)的情况下，每个时隙包括14个OFDM符号；在扩展CP的情况下，每个时隙包括12个OFDM符号。为了便于说明，在本公开中仅以每个时隙包括14个OFDM符号为例进行说明。根据本公开的实施例，针对一个时隙的时隙格式可以包括对该时隙所包括的14个OFDM符号的上下行配置信息，即14个OFDM符号中的每个OFDM符号是DL符号、UL符号还是X符号。也就是说，格式配置单元220可以为链路配置在一个时隙格式周期中包括的每个时隙的时隙格式，即格式配置单元220可以为链路配置在一个时隙格式周期中包括的所有OFDM符号的类型(DL、UL或X)。
由此可见，根据本公开的电子设备200，可以根据链路的子载波间隔为其配置时隙格式周期以及时隙格式，从而优化IAB系统中的时隙格式配置。
在5G NR通信系统中，允许不同的链路具有不同的子载波间隔。具体地，子载波间隔可以为15×2 μKHZ。这里，μ可以为非负整数。例如，当μ分别为0、1、2、3和4时，子载波间隔分别为15KHZ、30KHZ、60KHZ、120KHZ和240KHZ。进一步，针对不同的子载波间隔，一个时隙都包括14个OFDM符号，但是每个OFDM符号在时域上的长度不同。也就是说，针对具有不同子载波间隔的链路，一个时隙在时域上的长度不同。
图3是示出根据本公开的实施例的NR通信系统中的子载波间隔与时隙的长度的关系示意图。图3示出了在μ分别为0、1、2、3和4的情况下一个时隙在时域上的长度。在图3中，阴影部分表示一个时隙的长度。如图3所示，在μ＝0(子载波间隔为15KHZ)的情况下，一个时隙在时域上的长度为1ms，即1ms的子帧包括一个时隙；在μ＝1(子载波间隔为30KHZ)的情况下，一个时隙在时域上的长度为500μs，即1ms的子帧包括两个时隙；在μ＝2(子载波间隔为60KHZ)的情况下，一个时隙在时域上的长度为250μs，即1ms的子帧包括四个时隙；在μ＝3(子载波间隔为120KHZ)的情况下，一个时隙在时域上的长度为125μs，即1ms的子帧包括八个时隙；在μ＝4(子载波间隔为240KHZ)的情况下，一个时隙在时域上的长度为62.5μs，即1ms的子帧包括十六个时隙。由此可见，子载波间隔越大，一个时隙在时域上的长度越短，一个1ms的子帧包括的时隙数目越多。
根据本公开的实施例，周期配置单元210可以为链路配置时隙格式周期以使得链路的子载波间隔与时隙格式周期中包括的时隙的数目成正比。也就是说，链路的子载波间隔越大，该链路的一个时隙格式周期中包括的时隙的数目越多。
根据本公开的实施例，周期配置单元210可以将链路的时隙格式周期在时域上的长度配置为等于电子设备200与电子设备200的父节点之间的链路的时隙格式周期在时域上的长度，或者等于电子设备200与电子设备200的其它子节点之间的链路的时隙格式周期在时域上的长度。
根据本公开的实施例，在IAB系统中的每条链路的时隙格式周期在时域上的长度都可以相等。优选地，时隙格式周期在时域上的长度可以为一个子帧的长度(即1ms)的倍数。更优选地，时隙格式周期在时域上的长度可以为一个子帧的长度，即1ms。
图4是示出根据本公开的实施例的子载波间隔与时隙格式周期的关系示意图。在图4所示的示例中，时隙格式周期在时域上的长度可以为一个子帧的长度，即1ms。如图4所示，在子载波间隔为15KHZ的情况下，1ms的长度包括一个时隙，因此时隙格式周期为1；在子载波间隔为30KHZ的情况下，1ms的长度包括两个时隙，因此时隙格式周期为2；在子载波间隔为60KHZ的情况下，1ms的长度包括四个时隙，因此时隙格式周期为4；在子载波间隔为120KHZ的情况下，1ms的长度包括八个时隙，因此时隙格式周期为8；在子载波间隔为240KHZ的情况下，1ms的长度包 括十六个时隙，因此时隙格式周期为16。也就是说，在μ分别为0、1、2、3和4的情况下，周期配置单元210可以分别配置时隙格式周期为1、2、4、8和16。
如图2所示，电子设备200还可以包括通信单元230，用于发送和接收信息。
根据本公开的实施例，电子设备200可以利用通信单元230将时隙格式周期发送至子节点。例如，电子设备200可以利用高层信令发送时隙格式周期。这里，高层信令包括但不限于RRC信令。表1以非限制性的方式示出了在RRC信令中添加的表示时隙格式周期的字段slotformat_cycle和值的一个示例。

slotformat_cycle {1,2,4,8,16}
例如，电子设备200可以在UL-DL-Configuration-common、UL-DL-Configuration-common-set2和UL-DL-Configuration-dedicate这三个RRC信令中增加如下所示的代码：
Figure PCTCN2019098957-appb-000001
Figure PCTCN2019098957-appb-000002
如上所述，周期配置单元210可以为电子设备200与电子设备200的子节点之间的链路配置时隙格式周期。进一步，周期配置单元210还可以将配置的时隙格式周期发送至格式配置单元220，以用于格式配置单元220根据时隙格式周期配置时隙格式周期中的每个时隙的时隙格式。下面将详细描述格式配置单元220的操作。
图5是示出根据本公开的实施例的在RN接收信息的情况下和在RN发送信息的情况下的信息流向的示意图。
图5的上部示出了在RN接收信息的情况下的信息流向的示意图。这里，以RN2为例，当RN2接收信息时，其不能发送信息，因此可以接收来自RN3、UE1和RN1的信息，其中与RN3之间的BH链路方向为上行，与UE1之间的AC链路的方向为上行，而与RN1之间的BH链路的方向为下行。类似地，图5的下部示出了在RN发送信息的情况下的信息流向的示意图。这里，当RN2发送信息时，其不能接收信息，因此可以向RN3、UE1和RN1发送信息，其中与RN3之间的BH链路方向为下行，与UE1之间的AC链路的方向为下行，而与RN1之间的BH链路的方向为上行。由此可见，在同一时间，一个节点与其父节点之间的链路方向和该节点与其子节点之间的链路方向相反。进一步，当一个节点具有多个子节点时，该节点与每个子节点之间的链路方向相同。
根据本公开的实施例，格式配置单元220可以为电子设备200与其子节点之间的链路配置时隙格式，从而使得时隙格式周期内的每个符号的上下行配置与电子设备200和电子设备200的父节点之间的链路的时隙格式周期内的相应符号的上下行配置相反、或者与电子设备200和电子设备200的其它子节点之间的链路的时隙格式周期内的相应符号的上下行配置相同。
根据本公开的实施例，当电子设备200为RN时，电子设备200存在父节点，因此，格式配置单元220可以为电子设备200与其子节点之间的链路配置时隙格式，从而使得时隙格式周期内的每个符号的上下行配置与电子设备200和电子设备200的父节点之间的链路的时隙格式周期内的相应符号的上下行配置相反。也就是说，针对某一个符号，当电子设备200和电子设备200的其它子节点之间的链路的上下行配置为UL时，电子设备200与该子节点之间的链路的上下行配置为DL；当电子设备200和电子设备200的其它子节点之间的链路的上下行配置为DL时，电子设 备200与该子节点之间的链路的上下行配置为UL；当电子设备200和电子设备200的其它子节点之间的链路的上下行配置为X时，电子设备200与该子节点之间的链路的上下行配置为X。
根据本公开的实施例，当电子设备200为DN时，电子设备200不存在父节点，因此，格式配置单元220可以为电子设备200与其子节点之间的链路配置时隙格式，从而使得时隙格式周期内的每个符号的上下行配置与电子设备200和电子设备200的其它子节点之间的链路的时隙格式周期内的相应符号的上下行配置相同。也就是说，针对某一个符号，当电子设备200和电子设备200的其它子节点之间的链路的上下行配置为UL、DL或X时，电子设备200与该子节点之间的链路的上下行配置也分别为UL、DL或X。也就是说，格式配置单元220可以为电子设备200与每个子节点之间的链路配置时隙格式，从而使得每条链路的上下行配置相同。
图6是示出半双工工作模式对于设计IAB系统的时隙格式的限制的示意图。如图6所示，假定在图1中所示的BH2链路的子载波间隔为15KHZ，在图1中所示的BH3链路的子载波间隔为60KHZ，并且在图1中所示的AC2链路的子载波间隔为120KHZ，并且所有链路均采用前7个符号为DL符号，后7个符号为UL符号的时隙格式，则图6示出了在1ms的子帧长度内各个链路的时隙格式配置。如图6中的虚线框中所示，在同一时间，BH2链路和AC2链路为下行方向，即RN1发送数据，BH3链路为上行方向，即RN1接收数据。而在半双工工作模式下，RN1不可能同时发送数据和接收数据。因此，这种时隙格式是不合理的。
图7和和图8是示出根据本公开的实施例设计IAB系统的时隙格式的示意图。在图7中，存在DL、UL和X符号，而在图8中仅存在DL和UL符号。如图7和图8所示，在任意时间点，BH2链路、BH3链路和AC2链路的上下行方向一致。这里，虽然在图7中存在上下行方向不确定的X符号，但是在配置了时隙格式之后，父节点可以向子节点通知X符号的上下行配置，在配置X符号的过程中仍然遵循配置时隙格式的原则，即一个节点与其父节点之间的链路的上下行配置与该节点与其子节点之间的链路的上下行配置相反，并且一个节点与其每个子节点之间的链路的上下行配置相同。
如上所述，根据本公开的实施例，在IAB系统中，一个节点与其父节点之间的链路的上下行配置与该节点与其子节点之间的链路的上下行配置相反，并且一个节点与其每个子节点之间的链路的上下行配置相同。 这样一来，在任意一个时间点，一个节点与其每个子节点之间的链路传输方向相同，并且均与该节点与其父节点之间的链路传输方向相反，从而能够保证该节点要么在发送信息，要么在接收信息，从而满足IAB系统半双工工作模式的要求。
如图2所示，根据本公开的实施例，电子设备200还可以包括生成单元240，用于生成时隙配置信息，该时隙配置信息可以表示电子设备200与其子节点之间的链路在一个时隙格式周期内的每个时隙的时隙格式的信息。进一步，电子设备200可以通过通信单元230将时隙配置信息发送至子节点。
如图2所示，根据本公开的实施例，电子设备200还可以包括格式管理单元260，用于管理与电子设备200有关的各个链路(包括电子设备200与其父节点之间的链路、以及电子设备200与其子节点之间的链路)的时隙格式。这里，当电子设备200为电子设备200与其子节点之间的链路配置好时隙格式时，除了将该时隙格式发送至子节点之外，还可以将时隙格式存储在格式管理单元260中。由此，电子设备200和其子节点都知晓电子设备200与其子节点之间的链路的时隙格式，从而可以根据时隙格式执行上下行信息的传输。
根据本公开的实施例，生成单元240可以生成时隙配置信息，以使得时隙配置信息包括在一个时隙格式周期内的每个时隙的时隙格式的识别信息。也就是说，以时隙格式周期包括4个时隙为例，生成单元240可以生成如下的时隙配置信息：时隙格式1的识别信息；时隙格式2的识别信息；时隙格式3的识别信息；时隙格式4的识别信息。
在目前的3GPP标准中，已经定义了56种不同的时隙格式，分别编号为0-55。对于每一种时隙格式，分别定义了其中包括的14个符号的类型，即UL符号、DL符号或X符号。在这些已经定义的时隙格式中，除了编号为0的时隙格式(14个符号均为DL符号)和编号为1的时隙格式(14个符号均为UL符号)外，均包括UL符号、DL符号和X符号。
根据本公开的实施例，在格式配置单元220配置好了每个时隙的时隙格式之后，生成单元240可以确定每个时隙的时隙格式是否包括在已经定义的56种时隙格式中。在一个时隙的时隙格式已经包括在定义的56种时隙格式中的情况下，生成单元240可以确定该时隙格式的识别信息为其在0-55中的相应编号。进一步，在一个时隙的时隙格式没有被包括在定义的56种时隙格式中的情况下，生成单元240可以将该时隙的时隙格式 的识别信息定义为编号2。在编号为2的时隙格式中，14个符号均为X符号。
以图7所示的示例为例，针对BH2链路，时隙格式周期包括1个时隙，该时隙的时隙格式为DL、DL、DL、DL、DL、DL、X、X、UL、UL、UL、UL、UL、UL。这种时隙格式被包括在已经定义的56种时隙格式中，对应的编号为45。因此，生成单元240可以生成包括编号45的时隙配置信息。同样地，针对BH3链路，针对第1个时隙，该时隙的时隙格式为全下行，这种时隙格式被包括在已经定义的56种时隙格式中，对应的编号为0；针对第2个时隙，该时隙的时隙格式为DL、DL、DL、DL、DL、DL、DL、DL、DL、DL、X、X、X、X，这种时隙格式被包括在已经定义的56种时隙格式中，对应的编号为6；针对第3个时隙，该时隙的时隙格式为X、X、X、X、UL、UL、UL、UL、UL、UL、UL、UL、UL、UL，这种时隙格式被包括在已经定义的56种时隙格式中，对应的编号为13；针对第4个时隙，该时隙的时隙格式为全上行，这种时隙格式被包括在已经定义的56种时隙格式中，对应的编号为1。因此，生成单元240可以生成分别包括编号0、编号6、编号13和编号1的时隙配置信息。
根据本公开的实施例，当生成单元240生成的时隙配置信息表示的时隙格式中存在X符号时，电子设备200还可以向子节点发送关于该X符号的配置的信息。优选地，电子设备200可以通过低层信令，包括但不限于DCI来发送这样的信息。电子设备200可以采用各种已知的手段来发送关于X符号的配置的信息，本公开对此不做限定。
根据本公开的实施例，如上所述生成的时隙配置信息简单明了，且与现有的标准兼容，对现有标准的改动较小。此外，在这种情况下，允许X符号的存在，从而使得时隙配置更加灵活。
根据本公开的实施例，为了节约信令开销，生成单元240生成的配置信息还可以包括在一个时隙格式周期内发生上下行转换的一个或多个时隙中的每个时隙的识别信息以及该时隙的时隙格式的识别信息。
如图8所示，针对BH2链路，在一个时隙格式周期内发生一次上下行转换，这种转换发生在第1个时隙；针对BH3链路，在一个时隙格式周期内发生一次上下行转换，这种转换发生在第2个时隙；针对AC2链路，在一个时隙格式周期内发生一次上下行转换，这种转换发生在第4个时隙。因此，只要配置信息包括发生转换的时隙的识别信息以及该时隙的 时隙格式，子节点就可以知晓在整个时隙格式周期内每个符号的上下行配置。图8中仅仅示出了一个时隙格式周期发生一次上下行转换的情形，实际上一个时隙格式周期可以发生多次上下行转换，此时时隙配置包括每次发生转换的时隙的识别信息以及各个时隙的时隙格式。
根据本公开的实施例，通信单元230可以通过高层信令，包括但不限于RRC信令向子节点发送发生上下行转换的一个或多个时隙中的每个时隙的识别信息。表2以非限制性的方式示出了在RRC信令中添加的表示发生上下行转换的时隙的识别信息的字段slotformat_transposition和值的一个示例。这里，由于一个时隙格式周期最多包括16个时隙，因此slotformat_transpositio的值最大为16。

优选地，电子设备200可以在UL-DL-Configuration-common、UL-DL-Configuration-common-set2和UL-DL-Configuration-dedicate等RRC信令中增加相应的代码如下。

根据本公开的实施例，通信单元230可以通过低层信令，包括但不限于DCI向子节点发送发生上下行转换的一个或多个时隙中的每个时隙的时隙格式的识别信息。
前文中提到，在目前的3GPP标准中，已经定义了56种不同的时隙格式，分别编号为0-55。在向子节点发送发生上下行转换的时隙的时隙格式的识别信息时，很有可能该时隙格式不被包括在现有的56种时隙格式中。因此，为了进一步节约开销，在本公开中定义一些新的时隙格式，并对新的时隙格式进行编号，从而当电子设备200向子节点发送发生上下行转换的时隙的时隙格式的识别信息时，只需要发送该时隙格式的编号即可。此外，为了便于说明，下文中仅以在一个时隙格式周期中发生一次上下行转换为例进行说明，本领域技术人员可以理解，本公开的方案也可以推广至一个时隙格式周期包括多次上下行转换的情形。
表3中示出了新增的几种时隙格式。
表3
Figure PCTCN2019098957-appb-000005
Figure PCTCN2019098957-appb-000006
由此可见，在表3中定义了13中新的时隙格式，编号为56-68。在这些时隙格式中，均是下行符号在前，上行符号在后，并且下行符号的个数分别为1-13。由此，在电子设备200向其子节点发送发生上下行转换的时隙的时隙格式的识别信息时，可以直接发送时隙格式的编号。
根据本公开的实施例，如图2所示，电子设备200还可以包括存储单元250，用于存储本公开中新定义的时隙格式与编号的对应关系。
此外，在前文中提到，格式配置单元220可以将电子设备200与子节点之间的链路的上下行配置配置为与电子设备200和其它子节点之间的链路的上下行配置相同。为了进一步简化格式配置单元220的计算量，根据本公开的实施例，可以生成一个映射表，用于映射在不同子载波的情况下发生上下行转换的时隙的编号以及该时隙的时隙格式的编号。这样一来，格式配置单元220可以根据已经配置好的电子设备200与子节点的链路的发生上下行转换的时隙的编号以及该时隙的时隙格式的编号确定待配置的链路的发生上下行转换的时隙的编号以及该时隙的时隙格式的编号。
根据本公开的实施例，对于不同的子载波间隔，每个时隙格式周期中包括的时隙个数不同，因此每个时隙格式周期中包括的下行符号的个数也不同。表4示出了针对上述每一种新增的时隙格式，在不同的子载波间隔的情况下，每个时隙格式周期中包括的下行符号的个数。
表4
Figure PCTCN2019098957-appb-000007
Figure PCTCN2019098957-appb-000008
如表4所示，在μ＝0的情况下，每个时隙格式周期包括1个时隙，因此每个时隙格式周期中下行符号的个数等于对应的时隙格式中包括的下行符号的个数；在μ＝1的情况下，每个时隙格式周期包括2个时隙，因此每个时隙格式周期中下行符号的个数等于对应的时隙格式中包括的下行符号的个数的2倍，以此类推。
根据本公开的实施例，将表4中所示的每个时隙格式周期中包括的下行符号的个数对14取余，得到的商加1即为发生上下行转换的时隙的编号，得到的余数即为发生上下行转换的时隙中包括的下行符号的个数。表5示出了针对不同的子载波间隔和不同的时隙格式编号，得到的发生上下行转换的时隙中包括的下行符号的个数。
表5
Figure PCTCN2019098957-appb-000009
Figure PCTCN2019098957-appb-000010
根据发生上下行转换的时隙中包括的下行符号的个数可以确定发生上下行转换的时隙在表3中所对应的编号。例如，在μ＝0的情况下，发生上下行转换的时隙中下行符号的个数为1，对应于表3中编号为56的时隙格式，而在μ＝1的情况下，发生上下行转换的时隙中下行符号的个数为2，对应于表3中编号为57的时隙格式，而在μ＝2的情况下，发生上下行转换的时隙中下行符号的个数为4，对应于表3中编号为59的时隙格式，以此类推。由此可以确定表6。在表6中示出了在不同的子载波的情况下，发生上下行转换的时隙的编号和该时隙的时隙格式的编号之间的映射关系。其中，“无”表示不存在发生上下行转换的时隙。
表6
Figure PCTCN2019098957-appb-000011
Figure PCTCN2019098957-appb-000012
如表6所示，时隙编号表示发生上下行转换的时隙的编号，时隙格式编号表示发生上下行转换的时隙的时隙格式的编号。例如，在μ＝0的情况下，时隙编号是1，时隙格式编号为56表示在第1个时隙发生上下行转换，且该时隙的时隙格式为表3中所示的编号为56的格式。而与其对应的在μ＝1的情况下，在第1个时隙发生上下行转换，且该时隙的时隙格式为表3中所示的编号为57的格式。
根据本公开的实施例，存储单元250还可以存储例如表6所示的在下行符号在前的情况下，针对不同的子载波，发生上下行转换的时隙的编号和该时隙的时隙格式的编号之间的映射关系。这样一来，格式配置单元220可以根据存储单元250中存储的映射关系，根据已经配置好的链路的时隙格式为其它链路配置时隙格式。
以图8所示的示例为例，假定RN1已经为BH2链路配置好了时隙格式周期中包括的每个时隙的时隙格式，需要根据BH2链路的时隙格式配置BH3链路和AC2链路的时隙格式。如图8所示，对于BH2链路，μ＝0，发生上下行转换的时隙编号为1，该时隙的时隙格式编号为61。根据表6可以确定针对BH3链路，在μ＝2的情况下，发生上下行转换的时隙编号为2，该时隙的时隙格式编号为65，而针对AC2链路，在μ＝3的情况下，发生上下行转换的时隙编号为4，该时隙的时隙格式编号为61。
在表3中示出的新增的时隙格式中，均是下行符号在前上行符号在后。类似地，根据本公开的实施例，还可以新增一些上行符号在前下行符号在后的时隙格式，如表7所示。
表7
Figure PCTCN2019098957-appb-000013
Figure PCTCN2019098957-appb-000014
如表7所示，定义了13中新的时隙格式，编号为69-81。在这些时隙格式中，均是上行符号在前，下行符号在后，并且上行符号的个数分别为1-13。由此，在电子设备200向其子节点发送发生上下行转换的时隙的时隙格式的识别信息时，可以直接发送时隙格式的编号。同样地，存储单元250也可以存储这些新增的时隙格式。
进一步，根据本公开的实施例，可以根据以上类似的方法确定在上行符号在前的情况下，针对不同的子载波，发生上下行转换的时隙的编号和该时隙的时隙格式的编号之间的映射关系。如表8所示。
表8
Figure PCTCN2019098957-appb-000015
Figure PCTCN2019098957-appb-000016
根据本公开的实施例，存储单元250还可以存储例如表8所示的在上行符号在前的情况下，针对不同的子载波，发生上下行转换的时隙的编号和该时隙的时隙格式的编号之间的映射关系。这样一来，格式配置单元220可以根据存储单元250中存储的映射关系，根据已经配置好的链路的时隙格式为其它链路配置时隙格式。这与下行符号在前的情况类似，在此不再赘述。
根据本公开的实施例，如上所述生成的时隙配置信息中，可以仅包括发生上下行转换的时隙编号以及该时隙的时隙格式编号，从而可以节约信令开销。进一步，在这种情况下，时隙格式中不包括X符号，从而可以避免后续为了指示X符号的方向而产生的信令开销。
图9是示出根据本公开的实施例的父节点为子节点配置时隙格式周期和时隙格式的信令流程图。如图9所示，在步骤S901中，父节点为父节点与子节点之间的链路配置时隙格式周期。接下来，在步骤S902中，父节点为该链路配置在一个时隙格式周期内的每个时隙的时隙格式。接下来，在步骤S903中，父节点将该链路的时隙格式周期发送至子节点。接下来，在步骤S904中，父节点将该链路的在一个时隙格式周期内的每个时隙的时隙格式发送至子节点。由此，子节点可以获知其与父节点之间的链路的时隙格式周期以及时隙格式周期中每个时隙的时隙格式。
如上所述，根据本公开的实施例，IAB系统中的父节点可以为其与子节点之间的链路配置时隙格式周期以及时隙格式周期中的每个时隙的 时隙格式。这个过程通常发生在子节点初始接入的过程中。接下来，IAB系统中的各个节点可以根据配置好的时隙格式周期和时隙格式来执行上下行信息传输。下面将描述对IAB系统中的全部链路或部分链路的时隙格式的更新过程.
根据本公开的实施例，DN可以更新IAB系统中的全部链路的时隙格式。也就是说，DN可以为IAB系统中的每条链路配置更新后的一个时隙格式周期内的每个时隙的时隙格式，并且将更新后的时隙配置信息发送到相应节点，更新后的时隙配置信息表示更新后的在一个时隙格式周期内的每个时隙的时隙格式的信息。这里，相应节点包括一条链路两端的两个节点。
根据本公开的实施例，当电子设备200是DN时，格式配置单元220可以根据以下信息中的一种或多种来更新时隙格式：IAB系统中的每个节点的位置信息、IAB系统中的每个节点的波束方向、BSR(Buffer Status Report，缓存状态报告)消息、业务量以及IAB系统中每个节点的数据包的优先级。
根据本公开的实施例，电子设备200在向IAB系统中的其它节点发送更新的时隙配置信息之前，可以向其它节点发送更新请求信息。优选地，更新请求信息包括更新时隙格式的更新开始时间。这里，更新开始时间可以表示IAB系统中所有的链路更新时隙格式的开始时间。进一步，更新开始时间应当位于时隙格式周期的起始处。也就是说，假定时隙格式周期为一个子帧的长度，即1ms，则更新开始时间可以指示从哪个子帧开始采用更新后的时隙格式。例如，电子设备200可以通过包括但不限于RRC信令的高层信令向其它节点发送更新请求信息。
表9示出了需要在RRC信令中增加的一个字段和值的一个示例。其中，slotformat_changetime表示更新时隙格式的更新开始时间。

例如，电子设备200可以在UL-DL-Configuration-common、UL-DL-Configuration-common-set2和UL-DL-Configuration-dedicate等RRC信令中增加如下所示的代码：
Figure PCTCN2019098957-appb-000017
Figure PCTCN2019098957-appb-000018
根据本公开的实施例，电子设备200可以向IAB系统中的其它所有节点发送更新请求信息，并可以从其它节点接收更新响应信息。也就是说，在其它节点接收到更新请求信息的情况下，其它节点可以向电子设备200发送更新响应信息，由此电子设备200可以是否其它节点都接收到了更新请求信息。
根据本公开的实施例，更新响应信息可以表示自己、或者自己以及自己的子节点(如果可能，还包括子节点的子节点等)是否接收到了更新请求信息。当一个节点没有子节点时，当其接收到更新请求信息时，可以向该子节点的父节点发送ACK信息；当一个节点有子节点时，当其从所有的子节点接收到ACK信息时，可以向该节点的父节点发送ACK信息，当该节点的任意一个子节点没有反馈更新响应信息(或者反馈了NACK信息)时，该节点可以向其父节点发送NACK信息。因此，来自一个节点的更新响应信息可以表示该节点以下的所有节点是否全都接收到了更新请求信息。
根据本公开的实施例，当更新响应信息表明一个或多个其它节点没有收到更新请求信息时，向一个或多个其它节点重新发送更新请求信息。只有当更新响应信息表明所有节点均已收到更新请求信息时，电子设备 200才向IAB系统中的所有其它节点发送更新后的时隙配置信息。
如上所述，根据本公开的实施例，只有当所有节点都收到包括更新开始时间的更新请求信息时，电子设备200才向所有节点发送更新后的时隙配置信息。这样一来，可以保证IAB系统中的所有节点都能够获取更新开始时间，从而在更新开始时间处开始更新时隙格式。
根据本公开的实施例，电子设备200可以例如通过低层信令(包括但不限于DCI)向其它所有节点发送更新后的时隙配置信息。
根据本公开的实施例，在电子设备200向其它所有节点发送更新后的时隙配置信息之后，在更新开始时间处，电子设备200的格式管理单元260可以更新与电子设备200有关的链路的时隙格式。相应地，其它所有节点也都在更新开始时间处更新与自身有关的链路的时隙格式。
图10和图11是示出根据本公开的实施例的DN更新IAB系统中的所有节点的时隙格式的信令流程图。在图10和图11中，IAB系统采用如图1所示的结构。
如图10所示，在步骤S1001中，DN判定需要更新IAB系统中全部链路的时隙格式，从而向RN1和UE1发送更新请求信息。接下来，在步骤S1002中，RN1向其子节点RN2、RN3和UE2发送更新请求信息。接下来，在步骤S1003中，假定UE1接收到了来自DN的更新请求信息，因此向DN发送包括ACK信息的更新响应信息。进一步，假定RN2、RN3和UE2接收到了来自RN1的更新请求信息，因此向RN1发送包括ACK信息的更新响应信息。接下来，在步骤S1004中，由于RN1接收到了全部子节点的包括ACK信息的更新响应信息，因此向DN发送包括ACK信息的更新响应信息。接下来，由于DN接收到了来自全部子节点的ACK信息，因此在步骤S1005中，DN向UE1和RN1发送更新的时隙配置信息。接下来，在步骤S1006中，RN1向RN2、RN3和UE2发送时隙配置信息。这里，向RN1发送的时隙配置信息包括链路BH1、BH2、BH3和AC2的时隙格式，向UE1发送的时隙配置信息包括链路AC1的时隙格式，向RN2发送的时隙配置信息包括链路BH2的时隙格式，向RN3发送的时隙配置信息包括链路BH3的时隙格式，向UE2发送的时隙配置信息包括链路AC2的时隙格式。接下来，在步骤S1007中，当更新开始时间到来时，IAB系统中的所有节点都更新相关链路的时隙格式。例如，DN更新链路BH1和AC1的时隙格式，RN1更新链路BH1、BH2、BH3和AC2的时隙格式，UE1更新链路AC1的时隙格式，RN2更新链路BH2的时隙 格式，RN3更新链路BH3的时隙格式，UE2更新链路AC2的时隙格式。由此，整个IAB系统完成了时隙格式的更新。
如图11所示，在步骤S1101中，DN判定需要更新IAB系统中全部链路的时隙格式，从而向RN1和UE1发送更新请求信息。接下来，在步骤S1102中，RN1向其子节点RN2、RN3和UE2发送更新请求信息。接下来，在步骤S1103中，假定UE1接收到了来自DN的更新请求信息，因此向DN发送包括ACK信息的更新响应信息。进一步，假定RN2和UE2接收到了来自RN1的更新请求信息，因此向RN1发送包括ACK信息的更新响应信息，而RN3没有接收到来自RN1的更新请求信息，因此没有向RN1发送更新响应信息。接下来，在步骤S1104中，由于RN1没有接收到来自全部子节点的包括ACK信息的更新响应信息，因此向DN发送包括NACK信息的更新响应信息。接下来，在步骤S1105中，DN向RN1重新发送更新的时隙配置信息。接下来，在步骤S1106中，RN1向RN3重新发送更新的时隙配置信息。接下来，在步骤S1107中，假定RN3接收到了来自RN1的更新请求信息，因此向RN1发送更新响应信息。接下来，在步骤S1108中，RN1向DN发送包括ACK信息的更新响应信息。接下来，在步骤S1109中，DN向UE1和RN1发送更新的时隙配置信息。接下来，在步骤S1110中，RN1向RN2、RN3和UE2发送时隙配置信息。接下来，在步骤S1111中，当更新开始时间到来时，IAB系统中的所有节点都更新相关链路的时隙格式。由此，整个IAB系统完成了时隙格式的更新。
如上所述，根据本公开的实施例，DN可以更新整个IAB系统所有链路的时隙格式，并且更新后的时隙格式仍然符合IAB系统的半双工工作模式的要求。
根据本公开的实施例，RN可以更新IAB系统中部分链路的时隙格式。进一步，这种更新具备时效性。也就是说，RN对链路的时隙格式的更新是暂时性的。
根据本公开的实施例，当电子设备200是RN时，其可以更新电子设备200与其子节点之间的链路的时隙格式，也可以更新电子设备200与其父节点之间的链路的时隙格式。也就是说，格式配置单元220可以为电子设备100与其子节点之间的链路配置更新后的在一个时隙格式周期内的每个时隙的时隙格式，并且通信单元230可以向电子设备100的子节点发送更新后的时隙配置信息。进一步，格式配置单元220可以为电子设备 100与其父节点之间的链路配置更新后的在一个时隙格式周期内的每个时隙的时隙格式，并且通信单元230可以向电子设备100的父节点发送更新后的时隙配置信息。
根据本公开的实施例，更新后的时隙配置信息可以包括表示更新后的在一个时隙格式周期内的每个时隙的时隙格式的信息。优选地，电子设备200可以通过包括但不限于DCI的低层信令向其子节点发送更新后的时隙配置信息，并且可以通过包括但不限于UCI(Uplink Control Information，上行控制信息)的低层信令向其父节点发送更新后的时隙配置信息。
此外，根据本公开的实施例，当电子设备200具备多个子节点时，电子设备200可以更新与多个子节点中的每个子节点之间的链路的时隙格式。
进一步，根据本公开的实施例，电子设备200还可以向电子设备200的子节点和父节点发送用于更新时隙格式的更新开始时间和更新持续时间。这里，更新开始时间可以表示更新时隙格式的开始时间，更新开始时间应当在时隙格式周期的起始处。也就是说，假定时隙格式周期为一个子帧的长度，即1ms，则更新开始时间可以指示从哪个子帧开始采用更新后的时隙格式。更新持续时间可以表示更新时隙格式的持续时间，更新持续时间应当是时隙格式周期的整数倍。也就是说，假定时隙格式周期为一个子帧的长度，即1ms，则更新持续时间可以指示更新后的时隙格式将持续几个子帧。此外，更新开始时间和更新持续时间可以被包括在时隙配置信息中，也可以独立于时隙配置信息。例如，电子设备200可以在低层信令中添加如表10中所示的字段和值来表示更新开始时间和更新持续时间。其中，Slotformat-change-time表示更新开始时间，Slotformat-change-duration表示更新持续时间。

根据本公开的实施例，在更新后的电子设备200和电子设备200的子节点之间的链路以及电子设备200和电子设备200的父节点之间的链路的时隙格式中，增加了用于电子设备200发送信息的符号的个数。也就是说，当电子设备200希望增加发送信息的符号的个数时，可以更新电子设 备200与其子节点、以及电子设备200与其父节点之间的链路的时隙格式。这里，用于发送信息的符号可以是上行符号，也可以是下行符号。例如，电子设备200增加电子设备100与其子节点之间的链路的下行符号的个数，并且增加电子设备100与其父节点之间的链路的上行符号的个数。
图12是示出根据本公开的实施例的RN更新IAB系统中的部分节点的时隙格式的过程示意图。如图12所示，假定RN1是RN2的父节点，RN3是RN2的子节点，RN2与RN1之间的链路为BH1，RN2与RN3之间的链路为BH2。当RN2希望增加用于发送信息的符号的个数时，即对于BH1链路而言，增加了上行符号的个数，而对于BH2链路而言，增加了下行符号的个数。在这种情况下，RN2可以为BH1链路和BH2链路配置更新后的时隙格式，并生成相应的格式配置信息。进一步，RN2可以向RN1发送关于链路BH1的更新后的时隙格式的格式配置信息，并向RN3发送关于链路BH2的更新后的时隙格式的格式配置信息。
根据本公开的实施例，当电子设备200向其子节点和父节点发送更新后的配置信息之后，可以从子节点和父节点接收表示是否同意更新时隙格式的响应信息。进一步，当来自电子设备200的子节点的响应信息表示子节点同意更新时隙格式并且来自电子设备200的父节点的响应信息表示父节点同意更新时隙格式时，格式管理单元260可以在更新开始时间更新时隙格式，并且在更新持续时间之后，恢复更新前的时隙格式。在这种情况下，子节点和父节点也可以在更新开始时间更新时隙格式，并且在更新持续时间之后，恢复更新前的时隙格式。
根据本公开的实施例，当来自电子设备200的子节点的响应信息表示子节点不同意更新时隙格式和/或来自电子设备200的父节点的响应信息表示父节点不同意更新时隙格式时，不更新时隙格式。在这种情况下，电子设备200还可以向子节点和父节点发送表示不更新时隙格式的信息。优选地，电子设备200可以通过低层信令(包括但不限于DCI和UCI)来向子节点和父节点发送这样的信息。
根据本公开的实施例，DN可以在RRC信令中添加如下表所示的字段和值。其中，Slotformat-changebyRN-applicable表示是否允许RN更新IAB系统中的部分链路的时隙格式。

也就是说，只有在电子设备200被配置为允许更新IAB系统中的部分链路的时隙格式的情况下，电子设备200才可以如上所述更新其与子节点之间的链路的时隙格式以及其与父节点之间的链路的时隙格式。例如，可以在UL-DL-Configuration-common、UL-DL-Configuration-common-set2和UL-DL-Configuration-dedicate等RRC信令中添加如下代码：

图13和图14是示出根据本公开的实施例的RN更新IAB系统中的部分节点的时隙格式的信令流程图。在图13和图14中，采用了图12中所示的结构，即RN1是RN2的父节点，RN3是RN2的子节点。
如图13所示，在步骤S1301中，RN2为BH1链路和BH2链路设置更新后的时隙格式、更新开始时间以及更新持续时间。接下来，在步骤S1302中，RN2通过UCI向RN1发送BH1链路的更新后的时隙格式、更新开始时间以及更新持续时间，并通过DCI向RN3发送BH2链路的更新后的时隙格式、更新开始时间以及更新持续时间。接下来，在步骤S1303中，RN3向RN2发送响应信息，该响应信息表示RN3同意更新时隙格式。 接下来，在步骤S1304中，RN1向RN2发送响应信息，该响应信息表示RN1同意更新时隙格式。接下来，在步骤S1305中，在更新开始时间处，RN1、RN2和RN3更新相关链路的时隙格式。例如，RN1更新BH1链路的时隙格式，RN2更新BH1和BH2链路的时隙格式，RN3更新BH2链路的时隙格式。接下来，在步骤S1306中，在更新持续时间经过以后，RN1、RN2和RN3恢复之前的时隙格式。由此，RN2可以暂时性地改变其与子节点之间的链路以及其与父节点之间的链路的时隙格式。
如图14所示，在步骤S1401中，RN2为BH1链路和BH2链路设置更新后的时隙格式、更新开始时间以及更新持续时间。接下来，在步骤S1402中，RN2通过UCI向RN1发送BH1链路的更新后的时隙格式、更新开始时间以及更新持续时间，并通过DCI向RN3发送BH2链路的更新后的时隙格式、更新开始时间以及更新持续时间。接下来，在步骤S1403中，RN3向RN2发送响应信息，该响应信息表示RN3同意更新时隙格式。接下来，在步骤S1404中，RN1向RN2发送响应信息，该响应信息表示RN1不同意更新时隙格式。接下来，在步骤S1405中，RN2通过UCI向RN1发送表示不更新时隙格式的信息，并通过DCI向RN3发送表示不更新时隙格式的信息。在图14所示的示例中，RN1不同意更新时隙格式。根据本公开的实施例，如果RN3不同意更新时隙格式，或者RN1和RN3均不同意更新时隙格式，RN2也需要向RN1和RN3发送表示不更新时隙格式的信息。
由此可见，根据本公开的实施例，可以根据链路的子载波间隔为其配置时隙格式周期以及时隙格式。进一步，为了节约信令开销，本公开还定义了一些时隙格式并优化了上报时隙格式的方法。此外，DN可以更新整个IAB系统中所有链路的时隙格式，RN可以更新IAB系统中部分链路的时隙格式。综上，根据本公开的实施例，IAB系统中的时隙格式配置过程被优化。
