具体实施方式
为使本领域的技术人员更好地理解本公开实施例的技术方案，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
在本公开的描述中，除非另有说明，“/”表示“或”的意思，例如，A/B可以表示A或B。本文中的“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：仅A，仅B，以及A和B。此外，“至少一个”是指一个或多个，“多个”是指两个或两个以上。“第一”、“第二”等表述并不对数量和执行次序进行限定，并且“第一”、“第二”等表述也并不限定一定不同。
需要说明的是，本公开中，“示例性地”或者“例如”等表述用于表示作例子、例证或说明。本公开中被描述为“示例性地”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性地”或者“例如”等词旨在以详细方式呈现相关概念。
5G的新空口(New Radio，NR)协议从物理层协议R15开始就支持动态帧结构。动态帧结构中的每个时隙slot包含14个符号，编号为0-13。每个符号可以被配置为下行符号(downlink symbol，D symbol)、上行符号(uplink symbol，U symbol)或灵活符号(flexible symbol，F symbol)中的一种。需要说明的是，如果帧结构中的一个时隙被配置为上行时隙，帧结构下面的符号类型都为上行符号；如果帧结构中的一个时隙被配置为下行时隙，帧结构下面的符号类型都为下行符号；如果帧结构中的一个时隙被配置为灵活时隙，帧结构下面的符号类型都为灵活符号。示例性地，表1提供了一种动态帧的结构配置。
表1一种动态帧的结构配置
继续参考表1，对于上下行都可用的灵活符号的传输方向，基站侧可以通过无线资源控制(Radio Resource Control，RRC)信令重配帧结构、下行控制信息((Downlink Control Information，DCI))信令的时隙格式指示符((Slot Format Indicator，SFI))、用户设备(User Equipment，UE)级物理下行链路控制信道((Physical Downlink Control Channel，PDCCH))调度等多种方式来指示灵活符号的传输方向。基站侧通过RRC信令重配帧结构来指示灵活符号的传输方向，例如，基站侧根据RRC信令中的消息的一种或多种进行任意组合，并基于增加的配置字段，将帧结构中的灵活符号的符号类型配置为上行或者下行，最后基于符号类型指示灵活符号的传输方向。
基站侧通过DCI信令的SFI指示灵活符号的传输方向，例如，灵活符号和未知符号可以通过DCI信令重写以用于上行链路或者上行链路的传输，例如，基站可以通过动态信令组公共下行控制信道(Group Common PDCCH，GC-PDCCH)发送时隙格式SFI指示，SFI指示通过改变半静态配置的灵活符号和未知符号为上行符号或者下行符号，从而指示了灵活符号的传输方向。SFI可以指示灵活符号用于上行链路传输或者下行链 路传输。
随着通信技术的演进和第五代移动通信系统(5G)的大规模部署，越来越多的用户正在享受新一代移动通信技术带来的便利。未来5G业务将渗透到诸如虚拟现实(Virtual Reality，VR)、增强现实(Augmented Reality，AR)、线上医疗、工业物联网等领域，大量场景同时存在上行传输和下行传输并行、低时延等不同业务需求，基站侧单一的调度方式难以同时满足不同UE端的差异化业务需求。例如，在线上医疗场景中，手术的实时性和准确性同时对通信的时延和上行吞吐量有高的要求；在工业物联网领域中，存在机械臂控制的低时延业务和实时监控的高清上下行大流量业务等。
现有的商用5G网络大多采用固定的帧结构，固定的帧结构只能满足单一的业务特征，例如，DDDSU帧结构用于大下行业务场景或者大上行业务场景，DS帧结构用于低时延业务场景。显然，根据固定的帧结构进行资源的上下行调度，只能满足大上行、大下行或者低时延中的一种业务场景，难以满足多种业务并存的复杂场景。
动态帧结构从NR协议的R15开始出现，网络侧配置灵活符号(F symbol)或者灵活时隙(F slot)，这些灵活符号或者灵活时隙根据小区的业务特征可以做上下行切换，比如在大下行场景将F slot切换为D slot进行调度，在大上行场景将F slot切换为U slot进行调度。但这种切换是小区级的，且只能利用时分来满足小区级的大上行、大下行或低时延业务，无法同时满足小区内不同用户终端的差异化业务需求。
鉴于此，本公开实施例提供了一种数据传输方法，该方法通过根据终端的传输特征参数，来配置终端的无线帧的帧结构，以满足终端的个性化业务需求。这样，小区内不同业务需求的终端能够采用满足自身业务需求的帧结构(也即，本公开实施例提供的终端级别的帧结构)来进行数据传输。同时，基站还采用子带全双工技术，以避免不同终端采用不同的帧结构而导致的上下行信号干扰的问题。
本公开实施例提供的技术方案可以应用于各种通信系统，例如，采用5G通信技术的新空口(New Radio，NR)通信系统、未来演进系统或者多种通信融合系统等。
示例性地，图1示出了本公开实施例提供的一种通信系统的架构示意图。该通信系统可以包括基站10以及一个或多个终端11，基站10可以与该一个或多个终端11通信连接。需要说明的是，图1仅为示例性框架图，图1中包括的设备的数量，各个设备的名称不受限制，且除图1所示的设备外，通信系统还可以包括其他设备，如核心网设备。
基站10可以用于实现终端的资源调度、无线资源管理、无线接入控制等功能。例如，基站可以是小型基站、无线接入点、收发点(Transmission Receive Point，TRP)、传输点(Transmission Point，TP)以及其它接入节点中的任一节点。
终端11也可以称为终端设备、用户设备、移动台、移动终端等。示例性地，终端可以是手机、平板电脑、带无线收发功能的电脑、虚拟现实终端、增强现实终端、工业控制中的无线终端、无人驾驶中的无线终端、远程手术中的无线终端、运输安全中的无线终端、智慧城市中的无线终端、智慧家庭中的无线终端等等。本公开实施例对终端所采用的设备形态不做限定。
在一些实施例中，基站10可以采用子带全双工技术。子带全双工技术即为在单个载波内划分出不重叠的上行子带和下行子带，在上行子带上进行上行传输，在下行子带上进行下行传输，以实现基站侧的全双工。示例性地，图2为本公开一些实施例的一种子带全双工的示意图。如图2所示，为了避免上行子带和下行子带之间的互相干扰，上行子带和下行子带之间还可以存在保护带。
本公开的实施例的应用场景不做限定。本公开实施例描述的系统架构以及业务场景是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定。本领域普通技术人员 可知，随着网络架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
如图3所示，本公开实施例提供一种数据传输方法，应用于图1所示的通信系统中的基站10，该方法包括以下步骤。
S101、根据终端的传输特征参数，确定终端对应的无线帧的帧结构。
帧结构用于指示无线帧中各个时间单元的类型。也即，帧结构可以用于指示无线帧中各个时间单元是上行时间单元还是下行时间单元。本公开实施例中的时间单元可以为时隙、微时隙、符号等，对此不作限定。
在一些实施例中，如图4所示，S101例如可以实现为S1011和S1012。
S1011、根据终端的传输特征参数，确定无线帧的帧结构配置参数。
传输特征参数包括上行传输速率和下行传输速率。在一些实施例中，传输特征参数还可以包括时延要求和/或无线帧中各个时间单元的干扰特征。应理解，传输特征参数还可以包括其他类型的参数，对此不作限定。
在一些实施例中，上行传输速率和下行传输速率可以根据基站侧内部的流量统计结果和/或核心网流量统计结果来确定。例如，基站可以根据历史时间段内的流量统计结果，以历史时间段内的上行传输速率作为当前时刻的终端所需求的上行传输速率，以历史时间段内的下行传输速率作为当前时刻的终端所需求的下行传输速率。又例如，基站还可以根据历史时间段内的流量预计结果，预测出当前时刻的终端所需求的上行传输速率和下行传输速率。在一些实施例中，基站采用的预测算法可以基于长短时记忆神经网络(Long Short-term Memory Networks,LSTM)等方式来实现，对此不作限定。
在一些实施例中，上行传输速率和下行传输速率可以根据终端的业务类型来确定。例如，基站可以根据终端的业务对应的5G业务质量标识(5G QoS identifier，5QI)来确定上行传输速率和下行传输速率。应理解的是，每个5QI对应一种QoS策略，该QoS策略可以规定上行传输速率、下行传输速率、时延要求或误码率等相关参数。
在一些实施例中，时延要求可以根据终端的业务类型来确定。例如，基站可以根据终端的业务对应的5QI来确定时延要求。在一些实施例中，时延要求可以包括分组时延预算(packet delay budget，PDB)，PDB用于指示数据包在终端与用户面网元之间传输的时延上限值。例如，PDB为3ms，则表示终端发送的数据传输到用户面网元的时间不能超过3ms。
在一些实施例中，无线帧中各个时间单元的干扰特征可以是基站根据上下行测量结果来确定的。在一些实施例中，基站可以触发终端进行执行测量，例如基站触发终端进行信道状态信息参考信号(Channel State Information Reference Signal，CSIRS)或者信道探测参考信号(Sounding Reference Signal，SRS)的测量；之后，基站获取终端上报的测量报告，以获知上下行测量结果；进而，基站可以根据上下行测量结果确定无线帧中各个时间单元的干扰特征。在一些实施例中，干扰特征可以根据接收信号功率、接收信号的信干燥比、接收信号置信度等信号质量相关的参数来确定。在一些实施例中，一个时间单元的干扰特征可以包括该时间单元的上行干扰值和下行干扰值。上行干扰值用于表征该时间单元用于上行传输时受到干扰的程度。下行干扰值用于表征该时间单元用于下行传输时受到干扰的程度。
在一些实施例中，基站可以周期性地获取传输特征参数，以保证传输特征参数的时效性。因此，基站基于时效性强的传输特征参数所确定的帧结构能够更好地满足终端当前的业务需求。
在一些实施例中，与传输特征参数包括上行传输速率和下行传输速率相对应的，帧结构配置参数可以包括无线帧的上下行配比。上下行配比用于表征无线帧中上行时间单元的数目与下行时间单元的数目之间的 比值。上下行配比根据上行传输速率和下行传输速率确定。在一些实施例中，上下行配比根据上行传输速率和下行传输速率之间的比值来确定。例如，上下行时隙配比的时域范围为5ms，NR的子载波间隔为30kHz，则每毫秒内的时隙个数为2个，5ms时域范围总时隙个数为10个。如果上下行速率分别占比为0.8和0.2，则5ms时域范围需要配置8个上行时隙和2个下行时隙。
在一些实施例中，与传输特征参数还包括时延要求相对应的，帧结构配置参数还可以包括传输周期的大小。传输周期的大小用于表征传输周期包括的时间单元的数目。一个传输周期包括至少一个上行时间单元和至少一个时间单元。传输周期的大小根据时延要求来确定。在一些实施例中，传输周期的大小根据时延要求中的分组时延预算来确定。例如，以时间单元为符号为例，分组时延预算为3ms，且每毫秒内的时隙个数为2个，则传输周期的大小小于或等于6个时隙。这样，相邻的两个下行时间单元之间的时间间隔不会超过分组时延预算，以避免下行传输发生卡顿，保证下行传输满足时延要求。相邻的两个上行时间单元之间的时间间隔不会超过分组时延预算，以避免上行传输发生卡顿，保证上行传输满足时延要求。
在一些实施例中，与传输特征参数还包括无线帧中各个时间单元的干扰特征相对应的，帧结构配置参数还可以包括无线帧中各个时间单元支持的类型。一个时间单元支持的类型根据该时间单元的干扰特征来确定。
在一些实施例中，一个时间单元支持的类型根据该时间单元的干扰特征来确定，可以满足以下规则中的一项或者多项。
在时间单元的上行干扰值大于或等于第一阈值，且时间单元的下行干扰值小于第二阈值的情形下，时间单元支持的类型为下行时间单元；
在时间单元的上行干扰值小于第一阈值，且时间单元的下行干扰值大于或等于第二阈值的情形下，时间单元支持的类型为上行时间单元；
在时间单元的上行干扰值小于第一阈值，且时间单元的下行干扰值小于第二阈值的情形下，时间单元支持的类型包括上行时间单元和/或下行时间单元；
在时间单元的上行干扰值大于或等于第一阈值，且时间单元的下行干扰值大于或等于第二阈值的情形下，时间单元支持的类型包括上行时间单元和/或下行时间单元。
第一阈值和第二阈值可以根据终端的业务类型来确定。
例如，时隙slot0和时隙slot3的上行干扰值大于或等于第一阈值，且时隙slot0和时隙slot3的下行干扰值小于第二阈值，则时隙slot0和时隙slot3支持的类型为下行时隙；时隙slot9的上行干扰值小于第一阈值，且时间单元的下行干扰值大于或等于第二阈值，则时隙slot9支持的类型为上行时隙；时隙slot4的上行干扰值小于第一阈值，且时隙slot4的下行干扰值小于第二阈值，则时隙slot4支持的类型包括上行时隙和/或下行时隙。
应理解，本公开实施例基于时间单元的上下行的干扰情况，能够确定该时间单元支持的类型，以避免下行干扰严重的时间单元用于下行传输，以及避免上行干扰严重的时间单元用于上行传输，从而使得该无线帧的帧结构能够适应终端当前的通信环境，以获得较好的通信效果。
S1012、根据无线帧的帧结构配置参数，确定无线帧的帧结构。
例如，NR的子载波间隔为30kHz，则每毫秒内包含2个时隙，一个无线帧包含20个时隙，无线帧中的时隙从0开始编号可以为slot0-slot19。帧结构配置参数中上下行配比为0.2:0.8，传输周期的大小为3ms(或者说6个时隙)，slot0和slot3支持的类型为下行时隙，slot9支持的类型为上行时隙，除slot0、slot3以及slot9之外的其他时隙支持的类型包括上行时隙和下行时隙。基于此，基站可以确定适用于终端的无线帧 的帧结构例如为DDDDUDDDDUDUDDDDUDDD。
S102、根据帧结构以及子带配置信息，确定第一时频资源和第二时频资源。
子带配置信息用于配置上行子带和下行子带。也即，子带配置信息用于指示上行子带和下行子带在频域上的位置。在一些实施例中，子带配置信息可以包括上行子带的起始位置和带宽，下行子带的起始位置和带宽。这样，基于上行子带的起始位置和带宽，即可以确定上行子带在频域上的位置；同样地，基于下行子带的起始位置和带宽，即可以确定下行子带在频域上的位置。
本公开实施例中的子带配置信息可以是基站自身配置的，也可以是基站和终端协商确定的，还可以是核心网为基站配置的，对此不作限定。
第一时频资源包括所述无线帧中的至少一个上行时间单元以及上行子带上的至少一个频域单元，第二时频资源包括无线帧中的至少一个下行时间单元以及下行子带上的至少一个频域单元。
应理解的是，第一时域资源的大小(也即，第一时域资源包含的上行时间单元的数量和频域单元的数量)可以根据终端的上行传输需求来确定；同样地，第二时域资源的大小可以根据终端的下行传输需求来确定。
S103、在第一时频资源上调度终端发送数据，以及在第二时频资源上调度终端接收数据。
作为一种示例，基站可以向终端发送第一调度信息，以调度终端在第一时频资源上发送数据，该第一调度信息用于指示第一时频资源的位置。以及，基站可以向终端发送第二调度信息，以调度终端在第二时频资源上接收数据，该第二调度信息用于指示第二时频资源的位置。
在一些实施例中，第一调度信息和第二调度信息可以承载于下行控制信息(Downlink Control Information，DCI)中。
应理解的是，第一调度信息和第二调度信息可以在同一时刻发送，也可以在不同时刻分别发送。
本公开实施例中，通过终端的传输特征参数来确定适用于该终端的无线帧的帧结构，这样适用于该终端的无线帧的帧结构能够满足该终端的个性化的业务需求。
并且，由于基站采用了子带全双工的技术，因此即使不同终端的无线帧的帧结构存在不同，也不会导致不同终端的数据传输出现冲突。例如，终端A对应的帧结构中slot9为上行时隙，而终端B对应的帧结构中slot9为下行时隙，从而在slot9时，基站在上行子带上接收终端A发送的数据，在下行子带上向终端B发送数据，以避免两个终端的数据传输出现冲突。
可见，相比于一些技术中小区内各个终端仅能采用相同的帧结构(也即，小区级别的帧结构)来进行数据传输，本公开实施例中小区内不同业务需求的终端能够采用满足自身业务需求的帧结构(也即，本公开实施例提供的终端级别的帧结构)来进行数据传输，从而提高数据传输效率。
在一些实施例中，基站可以为小区内的各个终端均配置对应的终端级别的帧结构，以追求满足各个终端的个性化业务需求的目的。
在另一些实施例中，基站可以为小区中的一部分终端均配置对应的终端级别的帧结构，为小区中的另一部分终端配置小区级别的帧结构，以降低基站的配置压力。
可以理解的是，通信装置为了实现上述功能，通信装置包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到，结合本公开实施例描述的各示例的算法步骤，本公开能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本公开的范围。
