数据传输方法、装置和系统
本申请要求在2024年06月29日提交中国国家知识产权局、申请号为202410874141.X,发明名称为“数据传输方法、装置和系统”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
本申请涉及通信技术领域,并且更具体地,涉及一种数据传输方法、装置和系统。
背景技术
随着无线通信应用场景的日益丰富,无线通信过程中会产生很多面向新场景的数据,例如感知/成像数据、信道数据、人工智能(artificial intelligence,AI)数据等,这些数据具有数据量大、冗余较多、存在时域、频域、或空域相关性等特性,可以利用这些特性对待传输的数据进行压缩,以降低传输开销。
示例性地,针对原生数据,例如信道状态信息(channel state information,CSI)压缩、感知数据压缩、或AI数据(如训练、模型参数等)等,可以进行数据重组、数据过滤、数据变换、数据选择、量化、熵编码、或信道映射等操作,得到待发送的码流,然后进行信道编码、调制等处理后通过无线空口发送。然而,当前的数据重组方案可能无法适应不同任务或业务需求,也就无法保证传输性能。
发明内容
本申请提供一种数据传输方法、装置和系统,以期适应不同任务或业务需求,保证传输性能。
第一方面,提供了一种数据传输方法。该方法可以由第一装置(或编码设备)执行,在不特殊说明的情况下,本申请中的“第一装置”既可以指通信设备本身(例如,终端设备或网络设备),也可以是通信设备中的组件(例如,通信模组、处理器、电路、芯片、或芯片系统等),或者也可以是能实现全部或部分通信设备功能的逻辑模块或软件。
该方法包括:确定第一重组模式,第一重组模式用于指示针对第一数据类型的数据的分组方式,第一重组模式属于P个重组模式,P个重组模式与第一数据类型对应,P为大于1的整数;根据第一重组模式对第一数据类型的数据进行分组,得到第一数据分组;输出第一数据,第一数据是由第一数据分组经过处理得到的。
基于上述方案,第一装置可以确定第一重组模式,然后使用该第一重组模式对第一数据类型的数据进行分组。该实现方式,针对同一数据类型(例如第一数据类型)设计多种重组模式(例如P种重组模式),使得第一装置可以根据不同的业务或任务传输需求,灵活选择满足传输需求的第一重组模式进行数据分组,即支持多样化的数据传输需求,保证数据传输性能。同时,第一装置还可以结合具体压缩及传输需求进行重组模式的切换,从而提升端到端性能。另外,第一装置还可以将分组后的数据进行处理,例如数据选择、压缩、或量化等,支持动态匹配传输资源约束,可以将有限的传输资源用于发送更重要的分组数据,达到较好的信号丢弃效果,用于支持在物理层实现灵活、高效地数据压缩和传输,保证数据传输性能。
可选地,第一数据是由第一数据分组经过处理得到的,可以理解为:第一类型的数据经过第一重组模式进行分组后,可以再经过数据过滤、数据变换、数据选择(或者说数据丢弃)、量化、熵编码、信道映射、信道编码、或调制中的至少一项操作,得到第一数据。

可以理解,图1只是一种示例,对本申请的保护范围不构成限定。本申请实施例提供的通信方法还可以涉及图1中未示出的设备,如无线中继设备和/或无线回传设备等,当然本申请实施例提供的通信方法也可以只包括图1示出的部分设备。
随着无线通信应用场景的日益丰富,未来无线通信过程中会产生大量的原生数据(例如,无线接入网原生数据native data,或本地数据local traffic),这些原生数据对传输带来了新的需求。
图2是原生数据压缩及传输处理流程的示意图。如图2所示,在发送端,输入数据经过数据重组、数据过滤、数据变换、数据选择(或者说数据丢弃等)、量化、熵编码、信道映射等操作,得到待发送的码流,然后进行信道编码、调制等处理后通过无线空口传输。其中,输入数据可以是原生数据,例如感知数据、AI数据、或信道数据等。相应地,在接收端,首先通过解调、信道解码等操作得到二进制码流,再对二进制码流进行信道解映射、熵解码、反量化、数据恢复、数据反变换、数据补零、数据重组恢复等操作后输出重构数据。通常情况下,重构数据和输入数据的维度相等,对应的数据取值可能存在些许误差。
可以理解的,某一原生数据可以对应一种或多种数据类型。例如,针对不同的应用场景,传输过程可能会使用不同的数据类型。然而,当前针对某一原生数据对应的某一数据类型,通常采用固定的数据重组方案进行数据重组,无法支持在多种重组方案之间动态切换,也就无法适应不同任务或业务需求。因此,亟需定义针对特定数据类型的原生数据的多种重组方案,以支撑物理层压缩的标准化流程。
为了解决上述技术问题,本申请提供一种数据传输方法和装置,以期适应不同任务或业务需求,保证数据的传输性能。
下文将结合附图详细说明本申请实施例提供的数据传输方法,可以应用于上述图1所示的通信系统中。应理解,本申请实施例可以适用于发送端和接收端通信的场景。
还应理解,下文示出的实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定,只要能够通过运行记录有本申请实施例的提供的方法的代码或程序,以根据本申请实施例提供的方法进行通信即可。例如,本申请实施例提供的方法可以由第一装置(或编码设备)和第二装置(或解码设备)执行,在并不特殊说明的情况下,本申请中的“第一装置”或“第二装置”既可以指装置本身(例如,终端设备或网络设备),也可以是装置中的组件(例如,通信模组、处理器、电路、芯片(如调制解调(modem)芯片,又称基带(baseband)芯片,或包含modem核的SoC芯片或SIP芯片)、或芯片系统等),或者也可以是能实现全部或部分装置功能的逻辑模块或软件。
图3是本申请实施例提供的一种数据传输方法的流程示意图。如图3所示,该方法300包括如下多个步骤。
S310,第一装置确定第一重组模式。
其中,第一重组模式用于指示针对第一数据类型的数据的分组方式,第一重组模式属于P个重组模式,P个重组模式与第一数据类型对应,P为大于1的整数。
也就是说,第一装置在确定第一重组模式之后,也就确定第一数据类型的数据(例如,数据#a)对应的分组方式。其中,第一数据类型可以对应多个重组模式,每一个重组模式指示一种重组方案,即每一个重组模式对应数据#a的一种分组方式,第一重组模式是多个重组模式中的一个重组模式。
在本申请中,第一数据类型的数据(例如,数据#a)可以是原生数据,例如可以是感知数据、AI数据、或信道数据中的一种,或者也可以是其他原生数据,不予限定。数据#a对应的数据类型可以是一个或多个。例如,感知数据对应的数据类型包括:环境反射点、环境面片、环境重构地图、或射频地图中的至少一个,则感知数据对应的第一数据类型为环境反射点、环境面片、环境重构地图、或射频地图中的一个;再例如,AI数据对应的数据类型包括:AI训练数据、AI推理数据、AI模型参数、AI梯度参数、AI中间特征数据、或AI性能数据的至少一个,则AI数据对应的第一数据类型为AI训练数据、AI推理数据、AI模型参数、AI梯度参数、AI中间特征数据、或AI性能数据中的一个;又例如,信道数据对应的数据类型包括:信道矩阵(如多天线系统中设备反馈的H矩阵)、CSI矩阵、或信道指示信息(如信道质量指示(channel quality indicator,CQI)、或秩指示(rank indicator,RI))中的至少一个,则信道数据对应的第一数据类型为信道矩阵、CSI矩阵、或信道指示信息中的一个。
在本申请中,重组模式包括以下一项或多项:基于顺序拆分的重组模式,基于比特位置的重组模式,基于空间位置的重组模式,基于语义信息的重组模式,或者,基于重要性排序的重组模式。那么,第一重组模式可以是:基于顺序拆分的重组模式,基于比特位置的重组模式,基于空间位置的重组模式、基于语义信息的重组模式,或者,基于重要性排序的重组模式中的一个。
下面结合图4至图9,针对本申请实施例中涉及的重组模式及其对应的分组方式进行示例说明。
(1)基于顺序拆分的重组模式。
该重组模式中,根据数据存储或者记录的顺序进行划分得到不同的分组,实现复杂度低,可以支持多种数据类型。
图4是基于顺序拆分的重组模式对数据进行分组的结构示意图。如图4的(a)所示,第一数据类型为AI数据中的AI中间特征数据,该中间特征数据的长度(或个数)为N,按顺序从上到下依次均等划分为M个分组,即第一数据分组的个数为M,每个分组包含N/M个中间特征数据。如图4的(b)所示,第一数据类型为信道数据中的信道矩阵(例如H矩阵),该H矩阵的维度为N1*N2,例如针对第二个维度,按顺序从左到右依次均等划分为M个组,每个分组包含N2/M列数据,此时H矩阵的维度为N1*(N2/M))。可选地,针对该H矩阵的第一个维度,按顺序从上到下依次均等划分为M个组,每个分组包含N1/M行数据,此时H矩阵的维度为(N1/M)*N2/M。
可以理解的,上述重组模式对应的分组方式是采用均等划分的方式进行分组的,即M个分组中的每个分组包含的数据长度(或者说每个分组大小)相等,可选地,上述重组模式对应的分组方式也可以采用不均等划分的方式进行分组,即M个分组中至少存在两个分组的数据长度不等,对此不作限制。
可选地,针对图4所示的基于顺序拆分的重组模式,第一装置和第二装置需对齐针对第一数据类型的数据的分组方式。例如,针对上述分组方式所包含的分组个数M,以及每个分组的大小,可以是预定义或预配置的,此时无需显式地指示重组指示信息#1;再例如,该方法300还包括:第一装置/第二装置获取或输出重组指示信息#1,对于图4的(a),该重组指示信息#1指示分组的大小N/M或组数M;对于图4的(b),该重组指示信息#1指示分组的大小N2/M(或N1/M)或组数M。可选地,如果考虑非均匀大小的分组,则该重组指示信息#1指示M个分组中的每个分组的大小。
(2)基于比特位置的重组模式。
该重组模式中,首先将数据表示为比特流形式(如使用浮点数表示,或经过量化后表示),然后根据比特位的高低进行划分得到不同的分组,便于与比特分层、或增量传输等结合设计。
图5是基于比特位置的重组模式对数据进行分组的结构示意图。为便于描述和理解,以下示例中基于比特位置的重组模式对应的分组方式是采用均等划分的方式进行分组的,即M个分组中的每个分组包含的数据长度相等。
如图5的(a)所示,第一数据类型为感知数据中的环境反射点,该环境反射点的长度(或个数)为N,例如P1,P2,…PN,首先对N个环境反射点依次进行Q比特量化,M<Q,则N个数据可以得到一个N*Q的比特矩阵,然后对该比特矩阵的第二个维度(对应量化比特层)按顺序进行均等划分为M个分组,即第一数据分组的个数为M,每个分组包含Q/M个比特层,共计N*(Q/M)个比特。例如,以均等划分的方式对N个数据进行分组,此时Q=M,表示每个分组包括一个比特层,如图5的(a)的虚线框所示,即一列代表一个比特层。可选地,也可以对该比特矩阵的第一个维度(对应量化比特层)按顺序进行均等划分为M个分组,每个分组包含N/M个比特层,共计(N/M)*Q个比特。
可选地,上述图5的(a)对应的分组方式也可以采用不均等划分的方式进行分组,即M个分组中至少存在两个分组的数据长度不等,对此不作限制。此时Q≠M,表示每个分组可以包含不同个数的比特层,例如图5的(b)的虚线框所示,分组1可以包括两个比特层,分组M可以包括一个比特层。
如图5的(c)所示,第一数据类型为AI数据中的AI模型参数,该AI模型参数为N1*N2的矩阵,对每个参数进行Q比特量化,M<Q,则N1*N2个数据可以得到一个N1*N2*Q的三维比特矩阵,然后对该比特矩阵的第三个维度(对应量化比特层)按顺序进行均等划分为M个分组,每个分组包含Q/M个比特层,共计N1*N2*(Q/M)个比特。例如,以均等划分的方式对N个数据进行分组,此时Q=M,表示每个分组包括一个比特层,如图5的(c)的虚线框所示,即一个平面代表一个比特层。可选地,也可以对该比特矩阵的第一个维度按顺序进行均等划分为M个分组,每个分组包含N1/M个比特层,共计(N1/M)*N2*Q个比特。可选地,也可以对该比特矩阵的第二个维度按顺序进行均等划分为M个分组,每个分组包含N2/M个比特层,共计N1*(N2/M)*Q个比特。
可选地,上述图5的(c)对应的分组方式也可以采用不均等划分的方式进行分组,即M个分组中至少存在两个分组的数据长度不等,对此不作限制。此时Q≠M,表示每个分组可以包含不同个数的比特层,例如分组1可以包括两个比特层,也就是包括两个平面,分组4可以包括一个比特层,也就是包括一个平面,分组M可以包括三个比特层,也就是包括三个平面,等等,图中未示出。
可选地,针对图5所示的基于比特位置的重组模式,第一装置和第二装置需对齐针对第一数据类型的数据的分组方式。例如,针对上述分组方式所包含的分组个数M,以及每个分组的大小,可以是预定义或预配置的,此时无需显式地指示重组指示信息#2;再例如,该方法300还包括:第一装置/第二装置获取或输出重组指示信息#2,对于图5的(a),该重组指示信息#2指示分组的大小Q/M(或者N/M)或组数M;对于图5的(c),该重组指示信息#2指示分组的大小Q/M(或者N1/M、或N2/M)或组数M。可选地,如果考虑非均匀大小的分组,对于图5的(b),该重组指示信息#2指示M个分组中的每个分组的大小。
(3)基于空间位置的重组模式。
该重组模式中,根据数据所在的位置信息进行划分得到不同的分组,适用于具有地理位置信息的感知数据,可以结合地理位置信息对数据进行联合处理。
图6是基于空间位置的重组模式对数据进行分组的结构示意图。如图6所示,第一数据类型为感知数据中的射频地图(例如,基于二维坐标构建的射频地图),该射频地图包括射频参数1至射频参数14,将物理位置临近的多个射频参数化分为一组,得到4个分组,即第一数据分组的个数为M。例如,分组1包括射频参数1至射频参数4,分别对应的二维坐标信息是(x1,y1)、(x1,y2)、(x1,y3)和(x1,y4);分组2包括射频参数5至射频参数7,射频参数5对应的二维坐标信息是(x2,y1)和(x2,y2),射频参数6对应的二维坐标信息是(x2,y3),射频参数7对应的二维坐标信息是(x2,y4);分组3包括射频参数8、射频参数9和射频参数12,射频参数8对应的二维坐标信息是(x3,y1)和(x4,y1),射频参数9对应的二维坐标信息是(x3,y2),射频参数12对应的二维坐标信息是(x4,y2);分组4包括射频参数10、射频参数11、射频参数13和射频参数14,分别对应二维坐标信息(x3,y3)、(x3,y4)、(x4,y3)和(x4,y4)。
可以理解的,上述重组模式对应的分组方式是采用不均等划分的方式进行分组的,即M个分组中至少存在两个分组的数据长度(或者说射频参数的个数)不等,可选地,上述重组模式对应的分组方式也可以采用均等划分的方式进行分组的,即M个分组中的每个分组包含的射频参数的个数相等,对此不作限制。
可选地,针对图6所示的基于空间位置的重组模式,第一装置和第二装置需对齐针对第一数据类型的数据的分组方式。例如,针对上述分组方式所包含的分组个数M,以及每个分组包含的射频参数及其所在的坐标范围信息,可以是预定义或预配置的,此时无需显式地指示重组指示信息#3;再例如,该方法300还包括:第一装置/第二装置获取或输出重组指示信息#3,该重组指示信息#3可以包括每个分组对应的射频参数索引,例如以射频参数索引集合的形式指示,如分组1对应的索引集合为{1,2,3,4},分组2对应的索引集合为{5,6,7},分组3对应的索引集合为{8,9,12},分组4对应的索引集合为{10,11,13,14},通过发送射频参数索引可以确定对应的地理坐标信息。
(4)基于语义信息的重组模式。
该重组模式中,根据数据对应的语义类别进行划分得到不同的分组,适用于划分了语义特征的数据(如进行了语义分割的环境反射点、环境面片、环境重构地图等数据,这些数据对应的语义信息可以指示不同的对象、前景/背景等),可以结合数据语义特征对数据进行分组处理。
图7是基于语义信息的重组模式对数据进行分组的结构示意图。如图7所示,第一数据类型为感知数据中的环境面片,该环境面片包括大楼面片(例如,大楼1面片和大楼2面片),路灯面片(例如,路灯1面片、路灯2面片和路灯3面片)和街区路面面片。针对不同的对象,如大楼1、大楼2、路灯1、路灯2、路灯3和街区路面对应的面片进行区分,得到不同的分组环境面片数据,例如3个分组,即第一数据分组的个数为M=3。
可以理解的,上述重组模式对应的分组方式是采用不均等划分的方式进行分组的,即M个分组中至少存在两个分组的数据长度(或者说环境面片的个数)不等,可选地,上述重组模式对应的分组方式也可以采用均等划分的方式进行分组的,即M个分组中的每个分组包含的环境面片的个数相等,对此不作限制。
可选地,针对图7所示的基于语义信息的重组模式,第一装置和第二装置需对齐针对第一数据类型的数据的分组方式。例如,针对上述分组方式所包含的分组个数M,以及每个分组包含的环境面片,可以是预定义或预配置的;或者,环境面片数据隐含环境面片所在的坐标信息,此时无需显式地指示重组指示信息#4。
(5)基于重要性排序的重组模式。
该重组模式可以结合数据具体应用场景,获得不同重要性的数据码流,支持非均等保护UEP传输设计,即相对更重要的码流使用可靠度较高的信道编码、或调制方式;反之,相对不重要的码流使用可靠度较低的信道编码、或调制方式。
方式一:以信号功率或强度表征重要性,按照信号功率或强度对长度为N的数据进行排序,划分得到不同的分组,例如,将信号功率或强度高(重要性更高)的数据划分到一个分组,将信号功率或强度低(重要性较低)的数据划分到一个分组。
图8是基于重要性排序的重组模式对数据进行分组的一结构示意图。如图8所示,第一数据类型为感知数据中的射频地图(例如,以多径形式的射频地图数据),该射频地图中的每个径包括多径强度、相位、时延、到达角和离去角等信息,将多径强度较大的一个或多个径划分到一个分组中(作为相对更重要的信息),将多径强度较小的一个或多个径划分到一个分组中(作为相对不重要的信息)。例如,根据多径强度对数据进行划分得到M个分组,即第一数据分组的个数为M,每个分组包含一个或多个径的数据,比如分组1中的数据对应的多径强度最高(即最重要的分组),依次类推,分组M中的数据对应的多径强度最低(即最不重要的分组)。
方式二:以对下游AI任务的贡献度表征重要性,如针对AI相关任务如目标识别、定位等,可以先评估不同数据分量对任务精度的影响程度(影响程度越大,贡献度也越大;反之贡献度越小),用于衡量重要性并进行分组划分。
图9是基于重要性排序的重组模式对数据进行分组的另一结构示意图。如图9所示,第一数据类型为AI数据中的AI中间特征数据,长度为N,分别将每个中间特征数据置零后测试AI任务精度的下降值,根据精度下降值对N个AI中间特征数据进行排序分组得到M个分组,即第一数据分组的个数为M。例如,精度下降最大的AI中间特征数据作为最重要的信息,依次类推,精度下降最小的AI中间特征数据作为最不重要的信息,记录各AI中间特征数据的索引。每个分组可以包含AI中间特征数据的索引,例如分组1={1,3,…,N},表示将第1,3,…,N个AI中间特征数据划分为一个组,…,分组M={4,7,…,N-2},表示将第4,7,…,N-2个AI中间特征数据划分为一个组。
可选地,针对上述方式一或方式二,每个分组包含的数据的个数不作限定,可以相等,也可以不等,例如存在至少两个分组所包含的数据的个数不等。
可选地,针对图9所示的基于重要性排序的重组模式,第一装置和第二装置需对齐针对第一数据类型的数据的分组方式。例如,针对上述分组方式所包含的分组个数M,以及每个分组包含的数据,可以是预定义或预配置的,此时无需显式地指示重组指示信息#5;再例如,该方法300还包括:第一装置/第二装置获取或输出重组指示信息#5,该重组指示信息#5可以包括M个分组中的每个分组对应的数据的索引或编号。
上述图4至图9提供的重组模式及其对应的分组方式,仅是为便于理解给出的示例,不排除其他重组方案。可选地,本申请对重组模式的个数、每个重组模式划分的分组个数M,以及M个分组中的每个分组所包含的数据的个数不作限定。例如,本申请的重组方案可以均匀分组,也可以不均匀分组,例如针对长度为N的数据#a可以采用随机划分的方式进行分组。示例性地,通过随机种子确定M个分组中的每个分组对应的数据,第一装置和第二装置之间可以通过发送随机种子对应的编号或索引实现同步。可选地,第一装置和第二装置之间也可以协商,以其他任一方式对齐分组的方式,均属于本申请的保护范围,对此不作限定。

下面,针对上述步骤S310中第一装置确定第一重组模式的实现方式进行说明。
在一种实现方式中,该第一重组模式可以是预定义或预配置的。其中,预定义可以包括预先定义,例如协议定义,预配置可以通过在第一装置(和/或第二装置)预先保存相应的代码、表格、函数、文本、字符串或其他可用于指示相关信息(例如,第一重组模式)的方式来实现。

可选地,在第二装置根据第一数据类型和第一映射关系确定第一重组模式之前,该方法300还包括:第二装置获取第一数据类型。例如,该第一数据类型可以是预定义或预配置的;或者,第二装置获取指示信息#e,该指示信息#e用于指示第一数据类型,即该第一数据类型可以是终端设备通过信令指示或配置的。例如,第一装置向第二装置发送指示信息#e,该指示信息#e指示第一数据类型,对应地,第二装置接收指示信息#e,根据该指示信息#e确定该第一数据类型。
可选地,在第一装置获取指示信息#c之前,该方法300还包括:第一装置向第二装置发送指示信息#g(即,第三指示信息的一例),该指示信息#g用于指示第一装置的能力信息,或者,第一装置支持的一个或多个重组模式,其中,一个或多个重组模式包括第一重组模式。也就是说,第二装置根据接收的指示信息#g可以确定终端设备支持的一个或多个重组模式,进而结合第一数据类型和第一映射关系可以确定第一重组模式。例如,假设第一数据类型为感知数据中的环境面片,对应的多个重组模式包括:基于顺序拆分的重组模式和基于语义信息的重组模式,考虑到终端侧支持的重组模式为基于顺序拆分的重组模式,则第二装置最终确定的第一重组模式即为基于顺序拆分的重组模式。
可选地,该指示信息#b或指示信息#a或指示信息#c可以承载于第一信令或第一资源,第一信令包括无线资源控制(radio resource control,RRC)信令、下行控制信息(downlink control information,DCI)信令、或媒体接入控制控制元素(medium access control-control element,MAC CE),第一资源包括物理下行控制信道(physical downlink control channel,PDCCH)、或物理下行数据信道(physical downlink shared channel,PDSCH)。
可选地,该指示信息#d或指示信息#e或指示信息#f或指示信息#g可以承载于第二信令或第二资源,第二信令包括RRC信令、MAC CE信令、或上行控制信息(uplink control information,UCI)信令,第二资源包括物理上行控制信道(physical uplink control channel,PUCCH)、或物理上行数据信道(physical uplink shared channel,PUSCH)。
可以理解的,本申请对于第一装置确定第一重组模式的具体实现方式不作限定,只要第一装置和第二装置对齐该第一重组模式即可。
针对上述实现方式,第一装置(或第二装置)在确定第一重组模式之后,可以向第二装置(或第一装置)指示所选择的第一重组模式,具体示例如下。
作为一种示例,通过引入重组mode指示不同的重组模式。例如,假设定义了P种重组模式,则重组mode可以等于1,2,…,P,分别用于指示P种重组模式。
可选地,当第一数据类型只支持一种重组模式(即第一重组模式)时,则在确定第一数据类型时即可确定对应的重组mode,也就确定了该第一数据类型所支持的一种重组模式(即第一重组模式);当第一数据类型支持多种重组模式时,第一装置或第二装置可以通过信令配置或指示重组mode编号,进而确定第一数据类型对应的第一重组模式。
例如,第一装置或第二装置可以在RRC信令中新增一个重组模式reorganizeMode字段,该字段中可以携带重组mode的索引或编号,用于指示对应的重组模式。
举例来说,当P=5时,表示第一数据类型对应5个重组模式,5个重组模式一一对应5种重组方案,也即第一数据类型支持5种重组方案。其中,reorganizeMode中可以包含重组mode编号,如1、2、3、4、5,可以理解为:重组mode=1对应重组模式#1,重组mode=2对应重组模式#2,重组mode=3对应重组模式#3,重组mode=4对应重组模式#4,重组mode=5对应重组模式#5。即通过指示重组mode编号即可确定对应的重组模式。
再例如,reorganizeMode既可以直接指示重组mode编号,也可以指示特定mode集合中的元素索引。
举例来说,当P=5时,表示第一数据类型存在5个重组模式,5个重组模式一一对应5种重组方案,也即第一数据类型支持5种重组方案。假设某一数据类型支持的重组模式对应的重组mode编号分别为1,3,4,5,可选地,以集合的形式表征为{1,3,4,5},表示该数据类型支持的重组模式包括:重组模式#1、重组模式#3、重组模式#4和重组模式#5。那么,reorganizeMode的取值1~4分别对应重组mode=1、3、4、5,可以理解为:reorganizeMode的取值为1对应重组模式#1,reorganizeMode的取值为2对应重组模式#3,reorganizeMode的取值为3对应重组模式#4,reorganizeMode的取值为4对应重组模式#5。即reorganizeMode的取值即为对应的集合中的第几个重组方案。
作为另一种示例,通过比特信息指示不同的重组模式。例如,假设定义了P种重组模式,则第一装置可以使用个比特指示第一装置确定的第一重组模式,表示向上取整,P为大于或等于1的整数。比如,P=2,表示存在两种重组模式,则可以使用log2P=1比特信息指示确定的重组模式,比如“0”指示第一个重组模式,“1”指示第二个重组模式,假设第一装置选择第一个重组模式(即第一重组模式)对该第一数据类型的数据进行分组,则可以发送携带“0”指示信息,用于指示其选定的重组模式。
下面,针对上文提及的第一映射关系的表现形式进行示例说明。其中,该第一映射关系用于指示K个重组模式与L个数据类型之间的对应关系,该第一映射关系可以以表格,集合,函数,文本,或者,字符串的形式存在,如存储或传输,本申请对于其具体的实现方式不作限定。为便于理解,本申请以表格的形式对第一映射关系进行示例,如下表1或表2所示,表格中的“1”表示该数据类型支持对应的重组模式,“0”表示该数据类型不支持对应的重组模式。

作为一示例,该第一映射关系可以通过采用bitmap的方式存储或指示。其中,表1中的“1”和“0”分别记录为比特1和0,用于该数据类型是否支持该重组模式。例如,环境反射点支持基于顺序拆分的重组模式、基于比特位置的重组模式和基于空间位置的重组模式,对应的重组mode可以是1、2和3;再例如,AI训练数据支持基于顺序拆分的重组模式、基于比特位置的重组模式和基于重要性排序的重组模式,对应的重组mode可以是1、2和5;又例如,信道指示信息支持基于顺序拆分的重组模式,对应的重组mode可以是1,等等。
作为另一示例,该第一映射关系可以通过枚举的方式存储或指示,此时多个数据类型和多个重组模式之间的对应关系可以通过重组mode集合的方式表示。例如,感知数据中的环境反射点表示为{1,2,3},说明环境反射点支持重组mode=1,2,3对应的基于顺序拆分的重组模式、基于比特位置的重组模式和基于空间位置的重组模式;类似的,环境重构地图和射频地图均可以表示为{1,2,3}。再例如,AI数据中的AI训练数据表示为{1,2,5},说明AI中间特征数据支持重组mode=1,2,5对应的基于顺序拆分的重组模式、基于比特位置的重组模式和基于重要性排序的重组模式;类似的,AI模型参数表示为{1,2,5}。又例如,信道数据中的信道指示信息表示为{1},说明信道指示信息支持重组mode=1对应的基于顺序拆分的重组模式。

S320,第一装置根据第一重组模式对第一数据类型的数据进行分组,得到第一数据分组。
可选地,本申请对第一数据分组的分组个数,以及每个分组包含的数据大小不作限定,具体的分组方式可参考上述图4至图9的相关描述,为了简洁,此处不作说明。
例如,假设第一数据类型的数据的长度为N,根据第一重组模式对第一数据类型的数据进行分组得到的第一数据分组的个数为M,M为大于1且小于N的整数。例如N=8,M=4,说明存在长度为8的第一类型的数据,第一装置可以将该数据分为4组,则这4组可以包含等量(或等长度、或相同个数)的数据,即每组包含2个数据;或者,这4组可以包含不等量(或不等长度)的数据,如4组分别包含1,2,2,3个数据块。

可以理解的,上述方案主要针对使用第一重组模式对第一数据类型的数据进行分组,得到第一数据分组,以支持某一业务传输。可选地,考虑到第一数据类型对应P个重组模式,可以适应不同任务或业务需求,即第一数据类型支持不同的重组模式的灵活切换,从而保证传输性能。示例性地,针对同一数据类型,若网络侧的业务类型发生了变化,例如初始时反馈的第一数据用于数据融合,后续待反馈的第二数据用于执行特定检测任务,则可以采用不同的重组模式对第一数据类型的数据进行分组,满足不同任务或业务需求,提升端到端性能。
可选地,方法300还包括如下步骤S301至步骤S305。
S301,第一装置获取第四指示信息,例如,第二装置向第一装置发送第四指示信息,对应地,第一装置接收来自第二装置的第四指示信息,该第四指示信息用于指示第二重组模式,该第二重组模式用于指示针对第一数据类型的数据的分组方式。有关第二重组模式的具体释义和表现形式可以参考上文第一重组模式的相关描述,为了简洁,此处不作说明。
可选地,作为一种示例,在获取第四指示信息之前,方法300还包括:第一装置获取第五指示信息,例如,第二装置向第一装置发送第五指示信息,对应地,第一装置接收来自第二装置的第五指示信息,该第五指示信息用于指示第二映射关系,第二映射关系用于指示K’个重组模式与L’个数据类型之间的对应关系,K’个重组模式包括第二重组模式,L’个数据类型包括所述第一数据类型,K’为大于1的整数,L’为大于或等于1的整数。有关第二映射关系的具体释义和表现形式可以参考上文第一映射关系的相关描述,为了简洁,此处不作说明。
该实现方式中,第二装置可以通过发送第五指示信息,向第一装置更新数据类型和重组模式之间的对应关系,例如可以是指示从第一映射关系更新为第二映射关系,或者,也可以是指示从第三映射关系更新为第二映射关系,该第三映射关系可以是更新第一映射关系得到的。进一步地,第一装置通过获取第四指示信息和更新后的第二映射关系确定第二重组模式。

该实现方式中,第二装置可以通过发送第六指示信息,向第一装置指示第一数据类型对应的Q个重组模式,进一步地,第一装置通过获取第四指示信息可以确定更新后的第二重组模式。可选地,Q个重组模式可以以集合的形式存在,例如Q=4,对应重组mode={1,2,3,4},假设第一重组模式对应重组mode=1,则该第六指示信息可以包括重组mode=3,表示第二重组模式对应重组mode 3,例如基于空间位置的重组模式。
可选地,如果该第一数据类型对应的Q个重组模式等于步骤S310中的P个重组模式,则该第六指示信息可以不发送。
S302,第一装置根据第二重组模式对第一数据类型的数据进行分组,得到第二数据分组。
其中,第二数据分组与第一数据分组不同,可以理解为:第一数据分组和第二数据分组所包含的分组个数不同,例如,第一数据分组和第二数据分组所包含的分组个数分别为M和M”;和/或,第一数据分组所包含的a个分组所对应的数据内容与第二数据分组所包含的b个分组所对应的数据内容不同,可以是完全不同,也可以是部分不同,换言之,a个分组和b个分组中至少存在一个分组对应的数据内容不同。
可选地,第一数据分组和第二数据分组所包含的分组个数可以相同。如果第一数据分组和第二数据分组所包含的分组个数相同,例如M,则第一数据分组所包含的a个分组,与第二数据分组所包含的b个分组中至少存在一个分组对应的数据内容不同。
可选地,本申请对第二数据分组的分组个数,以及每个分组包含的数据大小不作限定,具体的分组方式可参考上述图4至图9的相关描述,为了简洁,此处不作说明。可以理解的,第一重组模式与第二重组模式不同,第一数据分组和第二数据分组也不同,以适应不同的业务传输需求。
例如,假设第一数据类型的数据的长度为N,根据第二重组模式对第一数据类型的数据进行分组得到的第二数据分组的个数为M”,M”为大于1且小于N的整数。例如N=8,M”=4,说明存在长度为8的第一类型的数据,第一装置可以将该数据分为4组,则这4组可以包含等量(或等长度、或相同个数)的数据,即每组包含2个数据;或者,这4组可以包含不等量(或不等长度)的数据,如4组分别包含1,1,2,4个数据块,对此不予限定。

上述步骤S304和S305的具体实现方式,可以参考上述步骤S340和S350的相关描述,为了简洁,此处不再赘述。
基于上述方案,第一装置可以确定第一重组模式,然后使用该第一重组模式对第一数据类型的数据进行分组。该实现方式,针对同一数据类型设计多种重组模式,使得第一装置可以根据不同的业务或任务传输需求,灵活选择满足传输需求的第一重组模式进行数据分组,即支持多样化的数据传输需求,保证数据传输性能。同时,第一装置还可以结合具体压缩及传输需求进行重组模式的切换,从而提升端到端性能。另外,第一装置还可以将分组后的数据进行处理,例如数据选择、或数据丢弃、或量化等,支持动态匹配传输资源约束,可以将有限的传输资源用于发送更重要的分组数据,达到较好的信号丢弃效果,用于支持在物理层实现灵活、高效地数据压缩和传输,保证数据传输性能。
上述图3至图9主要针对数据重组方案的相关描述,使得针对特定数据类型的数据,可以灵活选择或切换重组模式,以适应不同的业务传输需求。另外,为了支撑物理层压缩的标准化流程,满足对AI压缩场景下的码率调节需求,实现动态匹配传输资源约束,还可以针对分组后的数据进行压缩或丢弃。下面,结合图10至图15,针对上述步骤S330中第一装置的“该第一数据是由第一数据分组经过处理得到的”所涉及的数据选择方案(或者说,数据丢弃方案)以及量化方案进行说明。
可选地,该第一数据是由第一数据分组经过处理得到的,包括:对M个第一数据分组进行数据选择(或者说数据丢弃),得到第一数据。即,第一装置可以从M个第一数据分组中筛选或选择M’个第一数据分组,或者说,第一装置丢弃M个第一数据分组中的M-M’个第一数据分组。即该第一数据包括所述M’个第一数据分组。
在一种实现方式中,第一装置根据M个第一数据分组对应的重要性,从M个第一数据分组中选择M’个第一数据分组。
可选地,该M’个第一数据分组对应的重要性高于或等于M个第一数据分组中的其他M-M’个第一数据分组对应的重要性,也就是说,第一装置可以从M个第一数据分组中选择重要的M’个第一数据分组进行发送。
可选地,第一数据分组对应的重要性可以通过计算该第一数据分组包含的数据所对应的能量、或L1范数等重要性指标确定。可选地,重要性指标可以是预定义或预配置的,或者通过信令指示的。
例如,假设M=4,包括分组1、分组2、分组3和分组4,M’=2,说明第一装置可以根据分组对应的重要性,从这M个组中选择M’个组进行发送。如果这4个分组对应的重要性依次递减,则第一装置可以选择分组1和分组2发送。
再例如,假设M=4,包括分组1、分组2、分组3和分组4,M’=2,说明第一装置可以根据分组对应的重要性,从这M个组中选择M’个组进行发送。如果分组1对应的重要性最高,分组2、分组3和分组4对应的重要相等,则第一装置可以选择分组1和分组2发送,即存在多个分组对应的重要性相等的情况下,顺序选择其中的分组进行发送;或者,第一装置可以从分组2至分组4中随机选择一个分组,例如分组4,将分组1和分组4发送给第二装置,此时第一装置通过信令分组4即可,例如通过bitmap=“1001”或分组序号指示,例如“11”指示分组4。
图10是本申请实施例提供的分组筛选方案的示意图。如图10所示,假设第一数据类型的数据(例如,AI中间特征数据)的长度为N=8,根据确定第一重组模式对数据进行分组得到M=4个第一数据分组,例如包括分组1、分组2、分组3和分组4,假设M’=2,则说明第一装置根据这4个分组对应的重要性指标Im排序(如使用能量、或L1范数等度量各个分组的重要性)等信息从中筛选M’=2个分组。假设长度为8个数据的取值分别为xn,n=1,2,…,8,以能量度量分组的重要性为例,则有Im=x2m-1 2+x2m 2,m=1,2,3,4。例如,若I2≥I4≥I3≥I1,则说明分组2、分组4、分组3和分组1对应的重要性依次递减,即第一装置在确定M’=2的情况下,可以优先发送分组2和分组4对应的数据,即第一数据。
可选地,M’的取值可以通过资源约束确定,例如M’的取值可以是协议预定义或预配置的,或者,M’的取值可以是网络设备通过信令配置的,或者M’的取值可以是终端设备指示的等。
可选地,第一装置还可以向第二装置发送指示信息#A,该指示信息#A用于指示M’个第一数据分组。也就是说,第一装置可以通过发送指示信息#A,向第二装置指示从M个第一数据分组中选择的M’个第一数据分组。
举例来说,该指示信息#A可以包括第一比特位图(bitmap),其中,第一比特位图指示M’个第一数据分组,第一比特位图的大小为M比特;或者,该指示信息#A可以包括M’个第一数据分组对应的分组序号指示,分组序号指示的大小为比特。以图10为例,第一装置优先发送分组2和分组4对应的数据,在一种示例中,第一装置可以通过分组序号指示其选择的M’=2个分组,使用个比特开销,表示向上取整,该个比特可以携带在指示信息#A中,例如“00”指示分组1,“01”指示分组2,“10”指示分组3,“11”指示分组4,则可以在指示信息#A中携带“01”和“11”,指示第一装置发送分组2和分组4;或者,在另一种示例中,第一装置可以通过使用bitmap指示其选择的M’=2个分组,则该bitmap的大小为4比特,可以在指示信息#A中携带bitmap=‘0101’,指示第一装置发送分组2和分组4。
可选地,第一装置向第二装置指示M’个分组的具体实现方式,可以是协议预定义的,例如,协议指示第一装置与第二装置之间始终使用上述第一种示例或第二种示例中的实现方式指示M’个分组。可选地,第一装置可以采用动态切换的方式向第二装置指示M’个分组。例如,在指示信息#A的头部可以包括第一比特,如1bit,用于指示当前第一装置使用分组序号指示M’个第一数据分组(如比特“1”,此时指示信息#A中携带“1 10 11”),或者,使用第一比特位图指示M’个第一数据分组(如比特“0”,此时指示信息#A中携带“0 0101”)。
可选地,当M’较大时,采用第一比特位图的方式指示M’个分组的开销更低,反之,采用分组序号的方式指示M’个分组的效果更好。例如,针对第一装置需要标记实际发送的分组的优先级顺序时(如采用不等量化的场景),则第一装置可以采用分组序号的方式来表示。
可选地,第一装置还可以使用其他的方式指示M’个分组。例如,增加1bit用于指示M’=M,或M’<M,当M’=M时,指示信息#A的头部无需额外增加1bit,可以进一步节省指示开销。或者,第一装置可以隐式指示使用第一比特位图或分组序号指示的方式指示M’个第一数据分组,例如通过当前发送的第一数据的数据类型确定,当第一数据的数据类型是信道数据或CSI时,可以理解为:第一装置采用第一比特位图的方式来指示M’个分组;当第一数据的数据类型是感知数据、成像数据、或AI数据时,可以理解为:第一装置采用分组序号指示的方式来指示M’个分组。
可选地,该第一数据是由第一数据分组经过处理得到的,包括:对M个第一数据分组进行量化处理,得到第一数据,可选地,该量化处理可以在数据选择或数据丢弃方案之后执行,即第一装置对M’个第一数据分组进行量化处理得到第一数据。
在一种实现方式中,第一装置可以采用采用标量量化SQ方式或矢量量化VQ方式,其中,基于量化比特长度Q1对M’个第一数据分组中的M1个第一数据分组进行量化处理,得到第一数据,M1为大于0且小于或等于M’的整数,Q1为大于0的整数。
在另一种实现方式中,采用SQ方式或VQ方式,其中,基于量化比特长度Q2对M’个第一数据分组中的M2个第一数据分组进行量化处理,得到第一数据,M2为大于0且小于或等于M’的整数,Q2为大于或等于Q1的整数。
也就是说,假设M1等于M’,则第一装置可以使用SQ的方式,基于量化比特长度Q1对M1=M’个第一数据分组进行量化处理得到第一数据;或者,第一装置可以使用VQ的方式,基于量化比特长度Q1对M1=M’个第一数据分组进行量化处理得到第一数据。
也就是说,假设M1小于M’,M1+M2=M’,则第一装置可以使用SQ的方式,基于量化比特长度Q1对M1个第一数据分组进行量化处理得到第一数据的一部分,以及使用SQ的方式,基于量化比特长度Q2对M2个第一数据分组进行量化处理得到第一数据的另一部分;或者,第一装置可以使用SQ的方式,基于量化比特长度Q1对M1个第一数据分组进行量化处理得到第一数据的一部分,以及使用VQ的方式,基于量化比特长度Q2对M2个第一数据分组进行量化处理得到第一数据的另一部分;或者,第一装置可以使用VQ的方式,基于量化比特长度Q1对M1个第一数据分组进行量化处理得到第一数据的一部分,以及使用VQ的方式,基于量化比特长度Q2对M2个第一数据分组进行量化处理得到第一数据的另一部分;或者,第一装置可以使用VQ的方式,基于量化比特长度Q1对M1个第一数据分组进行量化处理得到第一数据的一部分,以及使用SQ的方式,基于量化比特长度Q2对M2个第一数据分组进行量化处理得到第一数据的另一部分。
可选地,该量化比特长度可以是预定义或预配置的,也可以是根据资源约束自行确定的。
可选地,本申请对M1和M2的数量以及大小关系不作具体限定。例如,M2等于M1,且M1+M2=M’,例如,第一装置可以将最重要的一半的第一数据分组(例如,M1个第一数据分组)采用量化比特长度为Q2=Q+1进行量化处理,将剩余的一半的第一数据分组(例如,M2个第一数据分组)采用量化比特长度为Q1=Q-1进行量化处理,以满足平均每个数据对应的量化比特长度为Q。
可选地,第一装置向第二装置发送指示信息#B,或者,第一装置接收来自第二装置的指示信息#B;其中,指示信息#B用于指示Q,Q表示用于对M’个第一数据分组进行量化的量化比特长度,Q为大于0的整数。例如,指示信息#B用于指示Q1,Q1表示用于对M’个第一数据分组中M1个第一数据分组进行量化的量化比特长度,和/或,指示信息#B用于指示Q2,Q2表示用于对M’个第一数据分组中M2个第一数据分组进行量化的量化比特长度。
在本申请中,量化比特长度可以替换为量化比特数、量化长度、量化比特、或量化分辨率,其中量化分辨率可以表示为SQ量化区间或VQ量化码字的数量,当量化比特长度越长时,对应的量化比特数、量化长度、或量化比特也越多,量化分辨率越高。
作为示例,当Q2等于Q1时,说明M’个第一数据分组采用相同的量化比特长度进行量化处理,即M1个第一数据分组和M2个第一数据分组采用相同的量化分辨率进行量化处理,即M个第一数据分组的量化精度相同,具体示例如下图11所示;当Q2大于Q1时,说明M2个第一数据分组采用的量化比特长度大于M1个第一数据分组采用的量化比特长度,可以理解的,该M2个第一数据分组对应的重要性高于M1个第一数据分组对应的重要性。针对Q2不等于Q1的情况,可以实现对M’个第一数据分组的动态非均等量化,以提升重构数据的整体量化精度。
可选地,第一装置还可以向第二装置发送指示信息#C,该指示信息#C用于指示量化配置,量化配置包括量化方式和量化参数。例如,当量化方式为SQ方式时,量化参数包括量化区间信息;再例如,当量化方式为VQ方式时,量化参数包括VQ码本矩阵信息;又例如,当量化方式为SQ方式和VQ方式时,量化参数包括量化区间信息和VQ码本矩阵信息。
也就是说,本申请对M’个第一数据分组采用的量化方式不作限定,可以是SQ方式和/或VQ方式,对应的,量化参数可以包括量化区间信息和/或VQ码本矩阵信息。

可以理解的,上述图11的(a)和图11的(b)对应的量化方式采用相同的量化精度,仅是为便于描述给出的示例,不排除其他方案,例如采用不同的量化精度对M’个第一数据分组进行量化处理。
可选地,在固定量化比特长度Q的情况下,第一装置可以动态选择合适的量化参数,如通过均方误差(mean-square error,MSE)、或平均绝对值误差(mean absolute error,MAE)等作为评价指标,选择MSE或MAE最小的量化参数用于量化。

可选地,针对上述步骤S340中的第二装置对第一数据进行处理得到第一数据分组,包括:第二装置对M-M’个第一数据分组进行补零操作得到重构的M个第一数据分组,M为大于1的整数。

可选地,针对该特征数据的重组(或分组)方式可以有一种或多种,不同的分组图案表征不同的分组映射关系。
S2:筛选M’个组。
应理解,该M’个组属于M个组,该M’个组的重要程度大于M-M’个组的重要程度,在降低传输开销的同时保证数据传输精度。
示例性地,编码单元根据M个组的重要程度,对步骤S1中的M个组进行排序,并从中选择M’个组。可选地,每个分组的重要程度可以通过计算该分组对应的能量或L1范数进行确定。
S3:量化操作。
示例性地,针对分组筛选得到的M’个分组,编码单元可以根据调度的资源确定量化比特长度Q,进而基于Q对M’个分组进行量化处理得到第一数据,Q为大于或等于1的整数。
S4:输出待发送的信号。
示例性地,待发送的信号包括数据码流(即第一数据)和指示信息#A,其中,指示信息#A表示分组筛选信息(对应S2,即第二指示信息),可选地,待发送的信号还包括用于指示第一重组模式的重组指示信息#1(对应S1,可参见上述图4)。可选地,待发送的信号还可以包括码本指示信息(对应S3,即指示信息#C),指示量化配置。
图15是本申请实施例提供的解码单元的处理流程的示意图。如图15所示,该解码单元的处理流程包括如下多个步骤。其中,以第一数据类型为AI中间特征数据、第一重组模式为基于顺序拆分的重组模式为了进行示例说明。

S6:分组筛选恢复。
示例性地,解码单元对第一装置筛选掉的M-M’个分组进行补零操作,然后根据指示信息#A中携带的分组筛选信息对M个分组恢复顺序,得到重构数据分组,例如重构数据分组1、重构数据分组2、重构数据分组3、…、重构数据分组M。
S7:特征数据恢复。
示例性地,解码单元根据重组指示信息#1,确定针对AI中间特征数据的分组方式,即基于顺序拆分的重组模式,然后对重构数据分组进行反映射操作(即,恢复特征数据顺序),得到重构的AI中间特征数据(例如,长度为N的矢量)。
基于上述方案,第一装置根据确定的第一重组模式,对第一数据类型的数据进行分组得到M个第一数据分组,并且从M个第一数据分组中筛选M’个第一数据分组(或者说,丢弃M-M’个第一数据分组)后量化处理并输出第一数据,不仅使得第一装置可以根据不同的业务或任务传输需求,灵活选择满足传输需求的第一重组模式进行数据分组,甚至可以为满足不同的业务需求灵活切换重组模式,即支持多样化的数据传输需求,保证数据传输性能。同时,第一装置还可以将M个第一数据分组进行处理,例如数据选择和量化处理等操作,适应不同的AI模型和/或传输场景,支持动态匹配传输资源约束,满足对AI压缩场景下的细粒度的码率调节需求,将有限的传输资源用于发送更重要的特征数据,达到较好的数据丢弃效果,以充分发挥AI模型的端到端性能,用于支持在物理层实现灵活、高效地数据压缩和传输。另外,采用动态优化量化配置的方案,可以进一步提升量化的精度,保障数据传输性能。
