具体实施方式
下面将参照附图更详细地描述本公开的实施例。虽然附图中显示了本公开的某些实施例，然而应当理解的是，本公开可以通过各种形式来实现，而且不应该被解释为限于这里阐述的实施例，相反提供这些实施例是为了更加透彻和完整地理解本公开。应当理解的是，本公开的附图及实施例仅用于示例性作用，并非用于限制本公开的保护范围。
在本公开的实施例的描述中，术语“包括”及其类似用语应当理解为开放性包含，即“包括但不限于”。术语“基于”应当理解为“至少部分地基于”。术语“一个实施例”或“该实施例”应当理解为“至少一个实施例”。术语“第一”、“第二”等等可以指代不同的或相同的对象。术语“和/或”表示由其关联的两项的至少一项。例如“A和/或B”表示A、B、或者A和B。下文还可能包括其他明确的和隐含的定义。
需要说明的是，本申请中“向A发送信息”，其中“向A”只是表示信息传输的走向，A是目的地，不限制“向A发送信息”一定是空口上的发送。“向A发送信息”包括直接向A发送信息，也包括通过发射机间接向A发送信息，所以“向A发送信息”也可以理解为“输出去向A的信息”。同理，“接收来自A的信息”，表示该信息的来源是A，包括直接从A接收信息，也包括通过接收机间接接收来自A的信息，所以“接收来自A的信息”也可以理解为“输入来自A的信息”。
可以理解，在本申请中，“指示”可以包括直接指示、间接指示、显式指示、隐式指示。当描述某一指示信息用于指示A时，可以理解为该指示信息携带A、直接指示A，或间接指示A。本申请中，指示信息所指示的信息，称为待指示信息。在具体实现过程中，对待指示信息进行指示的方式有很多种，例如但不限于，可以直接指示待指示信息，如待指示信息本身或者该待指示信息的索引等，也可以通过指示其他信息来间接指示待指示信息，其中，该其他信息与待指示信息之间存在关联关系。还可以仅仅指示待指示信息的一部分，而待指示信息的其他部分则是已知的或者提前约定的。例如，还可以借助预先约定(例如协议规定)的各个信息的排列顺序来实现对特定信息的指示，从而在一定程度上降低指示开销。待指示信息可以作为一个整体一起发送，也可以分成多个子信息分开发送，而且这些子信息的发送周期和/或发送时机可以相同，也可以不同。具体发送方法本申请不进行限定。其中，这些子信息的发送周期和/或发送时机可以是预先定义的，例如根据协议预先定义的，也可以是发射端设备通过向接收端设备发送配置信息来配置的。
本公开的实施例可以根据任何适当的通信协议来实施，包括但不限于，第三代(3rd Generation，3G)、第四代(4G)、第五代(5G)、第六代(6G)等蜂窝通信协议、诸如电气与电子工程师协会(Institute of Electrical and Electronics Engineers，IEEE)802.11等的无线局域网通信协议、和/或目前已知或者将来开发的任何其他协议。
本公开的实施例的技术方案应用于遵循任何适当通信协议的通信系统，例如：通用分组无线业务(General Packet Radio Service，GPRS)、全球移动通信系统(Global System for Mobile Communications，GSM)、增强型数据速率GSM演进系统(Enhanced Data rate for GSM Evolution，EDGE)、通用移动通信系统(Universal Mobile Telecommunications Service，UMTS)、长期演进(Long Term Evolution，LTE)系统、宽带码分多址系统(Wideband Code Division  Multiple Access，WCDMA)、码分多址2000系统(Code Division Multiple Access，CDMA2000)、时分同步码分多址系统(Time Division-Synchronization Code Division Multiple Access，TD-SCDMA)、频分双工(Frequency Division Duplex，FDD)系统、时分双工(Time Division Duplex，TDD)、第五代(5G)系统或新无线电(New Radio，NR)、第六代(6G)系统，等等。
AI技术可以被应用于网络层(如网络优化、移动性管理、资源分配等)和物理层(如信道编译码、信道预测、接收机等)。对于物理层的AI研究大多集中在物理层信号处理模块的模块替换上，如图1示出了物理层信号处理流程100的示意图，如图包括编码110、调制120、层映射(layer mapping，LM)和多入多出(multi-input multi-output，MIMO)130、波束形成140和射频(radio frequency，RF)150。在物理层应用AI技术能够在多个方面达到明显效果：多模块的联合优化，环境自适应调整、高维数据的联合处理、以及复杂难建模问题的数据驱动算法。但是，对于物理层模块来说，每个模块的独立优化算法距离性能上界已经非常接近，单纯的模块替换所能获得的增益空间不大。
在目前已有的一些方式中，可以将通信系统建模为自编码器结构。系统可以部署离线训练模型。当实际环境与系统模型失配时，可以通过发送训练数据进行在线训练，从而完成系统对新环境的适应。也就是说，在系统环境发生变化时，需要收发端重新进行端到端的训练，以保持系统较优的性能。但是实时训练时梯度的准确反向传播较难实现，并且实时训练会带来时延和训练开销。
为了解决上述问题以及潜在的其他问题，本公开提供了一种通信方法。本公开的实施例涉及术语“处理块(processing block，PB)”，处理块可以表示信号处理的数据块的大小，即信号处理的粒度，例如处理块可以包括n个频域资源和m个时域资源，n和m为正整数。在本公开的实施例中，第一装置经由第一信道接收来自第二装置的信号，该信号由第二装置基于第一发射机配置而生成；基于该信号确定第一信道的信道特性；基于第一信道的信道特性确定第二发射机配置，第二发射机配置至少指示处理块配置，处理块配置用于指示进行信号处理的处理粒度；并向第二装置发送第二发射机配置。以此方式，能够使得第二装置在不影响信号传输的情况下实时地更新发射机配置，一方面避免因环境变化导致的发射机配置不再准确的问题，另一方面也避免了额外的时延和训练开销。
图2示出了本公开的实施例能够实现于其中的示例场景200的示意图。在场景200中，示出了网络设备210，终端设备220-1和终端设备220-2，其中终端设备220-1和终端设备220-2可以分别或统称为终端设备220。网络设备210与终端设备220之间能够进行通信。终端设备220-1与终端设备220-2之间能够进行通信。
终端设备220可以包括向用户提供语音和/或数据连通性的设备，具体的，包括向用户提供语音的设备，或包括向用户提供数据连通性的设备，或包括向用户提供语音和数据连通性的设备。例如可以包括具有无线连接功能的手持式设备、或连接到无线调制解调器的处理设备。终端设备220可以是用户设备(user equipment，UE)、无线终端设备、移动终端设备、设备到设备通信(device-to-device，D2D)终端设备、车到一切(vehicle to everything，V2X)终端设备、机器到机器/机器类通信(machine-to-machine/machine-type communications，M2M/MTC)终端设备、物联网(internet of things，IoT)终端设备、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、远程站(remote station)、接入点(access  point，AP)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、或用户装备(user device)、卫星、无人机、气球或飞机等。例如，可以包括移动电话(或称为“蜂窝”电话)，具有移动终端设备的计算机，便携式、袖珍式、手持式、计算机内置的移动装置等。例如，个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、等设备。还包括受限设备，例如功耗较低的设备，或存储能力有限的设备，或计算能力有限的设备等。例如包括条码、射频识别(radio frequency identification，RFID)、传感器、全球定位系统(global positioning system，GPS)、激光扫描器等信息传感设备。作为示例而非限定，终端设备220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或智能穿戴式设备等，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。而如上介绍的各种终端设备，如果位于车辆上(例如放置在车辆内或安装在车辆内)，都可以认为是车载终端设备，车载终端设备例如也称为车载单元(on-board unit，OBU)。
网络设备210例如包括接入网(access network，AN)设备，例如基站或接入点，可以是指接入网中在空口通过一个或多个小区与无线终端设备220通信的设备，或者传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、移动交换中心以及设备到设备(Device-to-Device，D2D)、车辆外联(vehicle-to-everything，V2X)、机器到机器(machine-to-machine，M2M)通信中承担基站功能的设备等。又或者，网络设备210也可以是一种车到一切(vehicle-to-everything，V2X)技术中的网络设备为路侧单元(road side unit，RSU)。网络设备210可以包括长期演进(long term evolution，LTE)系统或高级长期演进(long term evolution-advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，或者也可以包括演进的分组核心网络(evolved packet core，EPC)、第五代移动通信技术(the 5th generation，5G)、新空口(new radio，NR)系统(也简称为NR系统)中的下一代节点B(next generation node B，gNB)或者也可以包括云接入网(cloud radio access network，Cloud RAN)系统中的集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，卫星、无人机、气球或飞机等，本发明并不限定。
图3示出了根据本公开的一些实施例的示例通信过程300的示意信令交互图。过程300涉及第一装置301和第二装置302。第一装置301可以被实现在网络侧，例如为如图2所示的网络设备210被包括在网络设备210中，或者，第一装置301可以被实现在终端侧，例如为如图2所示的终端设备220被包括在终端设备220中。第二装置302可以被实现在网络侧，例如为如图2所示的网络设备210被包括在网络设备210中，或者，第二装置302可以被实现在终端侧，例如为如图2所示的终端设备220被包括在终端设备220中。
示例性地，第二装置302可以被实现为发射机或者被包括在发射机内，第一装置301可以被实现为接收机或被包括在接收机内。本公开的实施例中，发射机和接收机可以进行神经网络联合信号处理，这样能获得联合信号增益。
在过程300中，第二装置302基于第一发射机配置和待发送数据生成(310)信号。在一些示例中，待发送数据可以是基于比特流得到的，信号可以为符号流。举例而言，待发送数据可以包括未编码的数据，或者可以包括经过信源编码后的比特流，或者可以包括经过信源信道编码后的比特流，本公开对此不限定。举例而言，所生成的信号可以为发送符号流。在 一些示例中，对待发送数据的处理可以包括编码、调制、波束形成、模数转换等操作中的一项或多项。
本公开的实施例中，第二装置302处可以具有发射机配置，例如该发射机配置可以是预先被配置的，可以是由第二装置302预先确定的，或者可以是在先前从第一装置301接收到的。示例性地，发射机配置可以包括处理块配置，例如被表示为PB＝(n,m)，其中n表示频域资源的数量，m表示时域资源的数量。举例而言，频域资源可以为物理资源块、物理资源单元、或子载波。举例而言，时域资源可以为符号、子帧、或时隙。以频域资源为PRB(或简称为RB)且时域资源为正交频分多路复用(orthogonal frequency division multiplexing，OFDM)符号为例，n取值可以是1、2、4、或8，m取值可以是1、2、N symb/2、或N symb，其中N symb表示每个时隙中的符号数。作为示例，可以假设在过程310时，第二装置302处的发射机配置为第一发射机配置。
在一些实施例中，第一发射机配置可以包括第一处理块配置，第一处理块配置可以表示信号处理的处理粒度。举例而言，第一处理块配置可以指示频域资源的数量和时域资源的数量。例如，第一处理块配置可以指示n＝n1个RB和m＝m1个OFDM符号，例如表示为PB＝(n1,m1)。在一些实施例中，第二装置302可以基于第一处理块配置将待发送数据进行划分，例如划分为多个处理块，每个处理块的大小为(n1,m1)。第二装置302可以针对多个处理块分别进行处理，例如针对每个处理块的处理是一样或类似的。也就是说，不同的处理块之间的处理方式是复用的。
举例而言，假设第二装置302需要发送包括4个RB、14和OFDM符号的数据。如果第一处理块配置指示PB＝(1,1)时，表示推理1次可得到1个RB(包括12个子载波)和1个OFDM符号的数据，即，每次推理输出12×1个复数符号，那么要得到4个RB，14个OFDM符号的数据，第二装置302可以针对(同一个)发射机神经网络推理共4×14次。如果第一处理块配置指示PB＝(4,7)时，那么第二装置302可以针对发射机神经网络推理共1×2次，其中每次推理输出48×7个复数符号。
在一些实施例中，第一发射机配置可以包括第一信道特性码字(channel feature code，CFC)，第一信道特性码字可以指示信道特性的量化结果。举例而言，第一信道特性码字可以被表示多个比特，例如32bit。在一些实施例中，第二装置302可以基于第一信道特性码字，确定信道特性。在一些实施例中，第二装置302可以基于第一信道特性码字，针对多个处理块中的每个处理块进行处理，例如该处理可以包括信道编码等。
在本公开的一些实施例中，第一发射机配置可以包括第一处理块配置和第一信道特性码字，第二装置302所发送的伪代码可以被表示为：
Figure PCTCN2022140179-appb-000001
其中M表示被调度的发送OFDM符号数，N表示被调度的发送RB数，s k,l表示发送符号向量，长度为12×n1×m1，k表示RB的序号，l表示OFDM符号的序号，
Figure PCTCN2022140179-appb-000002
表示PB＝(n1,m1)配置下的发射机，b表示输入的待发送数据，c表示信道特性码字，Q表示发射机的压缩 比，如输入维度为4，对应输出维度为1，则Q＝4。
在一些实施例中，第一发射机配置可以包括第一信道感知掩码，第一信道感知掩码可以指示在单个处理块内的采用预定调制方式的时频资源的位置。举例而言，第一信道感知掩码可以通过第一频域范围和第一时域范围来指示时频资源的位置，并且在所指示的时频资源处，采用预定调制方式进行调制。例如，预定调制方式可以包括以下任一种：幅移键控(amplitude shift keying，ASK)调制、相移键控(phase shift keying，PSK)调制、移频键控(frequency shift keying，FSK)调制、正交幅度调制(quadrature amplitude modulation，QAM)等。示例性地，信道感知掩码包括频域资源的索引和时域资源的索引。
在一些实施例中，第二装置302可以针对每个处理块，通过在第一信道感知掩码所指示的时频资源的位置处使用预定调制方式以及在其余位置处使用与预定调制方式不同的另一调制方式，来生成信号。示例性地，另一调制方式可以基于非规则星座映射表，非规则星座映射表可以是基于PB联合优化的，但其可以限制在资源单元(resource element，RE)之间不能进行联合调制。例如，若第一处理块配置指示PB＝(n1,m1)，那么，第二装置302可以确定12×n1×m1个星座图，对应于RB内的12×n1×m1个RE。
在本公开的一些实施例中，第一发射机配置可以包括第一处理块配置和第一信道感知掩码，第二装置302所发送的伪代码可以被表示为：
Figure PCTCN2022140179-appb-000003
其中，
Figure PCTCN2022140179-appb-000004
表示RB内子载波个数，s k×M/n1+i,l表示
Figure PCTCN2022140179-appb-000005
位置对应的调制符号，QAM(b,Q)表示QAM调制，b表示输入比特，Q表示调制阶数。
Figure PCTCN2022140179-appb-000006
表示PB＝(n1,m1)的非规则星座图，i表示RB内的子载波序号，l表示OFDM符号序号，sc_index表示第一信道感知掩码所指示的子载波的索引，sym_index表示第一信道感知掩码所指示的OFDM符号的索引。可理解，在第一发射机配置包括第一信道感知掩码的实施例中，RE星座图虽然是PB内联合优化的，但是每次调制时的RE独立的。
这样，可以通过第一处理块配置来控制或限定第二装置302的处理粒度。例如PB＝(1,1)时，即处理块包括1个RB一个OFDM符号，那么第二装置302可以一次处理1个RB(包括12个子载波)和1个OFDM符号的数据，即12×1个调制符号所对应的数据。但是可理解的是，即使第二装置302的处理能力很强，也不会跨PB进行符号的联合发送。由于神经 网络可以获得高维数据联合处理的性能增益，但是高维数据的排列组合对于第二装置302而言几乎是不可能一一列举的。因此，本公开的实施例通过第一处理块配置来限定处理粒度，能够权衡收发机性能和实现复杂度，提高了可扩展性和可复用能力。
第二装置302向第一装置301发送(320)信号322，相应地，第一装置301接收(334)该信号322。具体而言，第二装置302可以通过第一信道发送信号322，其中第一信道为数据信道。举例而言，第二装置302被实现在网络侧，第一装置301被实现在终端侧，第一信道可以为物理下行链路共享信道(physical downlink shared channel，PDSCH)。举例而言，第二装置302被实现在终端侧，第一装置301被实现在网络侧，第一信道可以为物理上行链路共享信道(physical uplink shared channel，PUSCH)。举例而言，第一装置301和第二装置302都被实现在终端侧，第一信道可以为物理边链路共享信道(physical sidelink shared channel，PSSCH)。
第一装置301确定(330)信道特性。在一些实施例中，第一装置301可以基于对经历第一信道的信号322的接收，来确定第一信道的信道特性。示例性地，第一信道的信道特性可以被用于由第一装置301来确定第二发射机配置。
在一些实施例中，第一装置301还可以基于信号322确定(如恢复)数据，例如数据可以为比特流。举例而言，第一装置301可以对接收到的信号322进行处理，以确定数据，在一些示例中，对信号322的处理可以包括数模转换、定时、载波恢复、解调制、解码等操作中的一项或多项。示例性地，第一装置301还可以基于信号322确定比特流中各个比特的对数似然比(log likelihood ratio，LLR)，例如LLR可以被输入到信道译码器以进行信号处理。在一些实施例中，相比于第二装置302，在第一装置301处可以实现更为自由的算法，例如可以不限制第一装置301的能力，例如在第一装置301处可以跨PB进行符合的联合处理。这样能够充分利用第一装置301的处理能力。
在一些实施例中，第一信道的信道特性可以表示第一信道的统计特性，例如可以被表示为信道矩阵、信道中多径分量的空-时-频的三维信息、或其他信息等。可选地，信道特性也可以被称为信道长期特征或其他名称，本公开对此不限定。以此方式，第一装置301可以在接收信号的过程中，来确定信道特性，从而该方案不需要预先独立地发送导频信号进行信道估计，这样能够减少信令开销。
第一装置301基于第一信道的信道特性来确定(340)第二发射机配置。在一些实施例中，第一装置301处可以被预先配置有配置生成算法，并且第一装置301可以基于该配置生成算法得到第二发射机配置。例如，配置生成算法的输入为信道特性，输出为第二发射机配置。
在一些实施例中，配置生成算法也可以被称为配置生成网络模型、配置生成神经网络、配置生成网络、配置模型、或其他名称等，本公开对此不限定。示例性地，可以预先训练配置生成算法，并将经训练的配置生成算法预先配置在第一装置301处。
在一些实施例中，第二发射机配置可以包括第二处理块配置，第二处理块配置可以表示信号处理的处理粒度。举例而言，第二处理块配置可以指示频域资源的数量和时域资源的数量。例如，第二处理块配置可以指示n＝n2个RB、m＝m2个OFDM符号，例如表示为PB＝(n2,m2)。
本公开的实施例中，第二处理块配置能够反应当前的第一信道的频/时域特性。可理解，当频/时域信道选择性大时，可以选择更大的n2,m2值，但是更大的n2,m2会带来更大的计 算开销，因此在实际确定的过程中需要权衡第一装置301和第二装置302的处理能力。换句话说，第二处理块配置能够被用于同时表征第一信道的频/时域特性、以及第一装置301和第二装置302的处理能力。以此方式，能够提高可扩展性和可复用能力。举例而言，n2取值可以是1、2、4、或8，m2取值可以是1、2、N symb/2、或N symb。示例性地，第二处理块配置可以占用4bit。
在一些实施例中，第二发射机配置可以包括第二信道特性码字，第二信道特性码字可以指示信道特性的量化结果。在一些示例中，第二信道特性码字可以具有第一预设长度，以兼顾精度以及传输开销。例如，如果长度超过第一预设长度，尽管能够提高精度，但是传输开销过大；相反，如果长度低于第一预设长度，尽管传输开销小，但是精度却低。作为一例，第一预设长度为32bit，也就是说，第二信道特性码字可以等于32bit。
在一些实施例中，第二发射机配置可以包括第二信道感知掩码。第二信道感知掩码可以指示在单个处理块内的采用预定调制方式的时频资源的位置。举例而言，第二信道感知掩码可以包括频域资源的索引和时域资源的索引。例如，频域资源包括PRB、PRE、或子载波，时域资源包括以下任一项：符号、子帧、或时隙。举例而言，预定调制方式可以为ASK、PSK、FSK、QAM等中的任一项。
作为一个示例，假设频域资源为子载波，时域资源为符号，预定调制方式为QAM。那么第二信道感知掩码可以指示子载波索引和符号索引，以表示在这些位置处要使用QAM。可理解，在信道失配时，使用非规则星座点会带来发射机的性能损失，而在本公开的实施例中，通过第二信道感知掩码能够指示采用预定调制方式(如QAM)的位置，这样能够在不重新训练的情况下降低性能损失。
在一些示例中，第二信道感知掩码可以具有第二预设长度，以兼顾精度以及传输开销。例如，如果长度超过第二预设长度，尽管能够提高精度，但是传输开销过大；相反，如果长度低于第二预设长度，尽管传输开销小，但是精度却低。作为一例，第二预设长度为26bit，也就是说，第二信道感知掩码可以等于26bit。
第一装置301向第二装置302发送(350)第二发射机配置352。可选地，在一些实施例中，第一装置301处也可以具有(例如存储有)第一发射机配置。第一装置301可以将第二发射机配置352与第一发射机配置进行比较，如果确定两者不同，则发送第二发射机配置352。如果确定两者相同，则可以不发送第二发射机配置352。
具体而言，第一装置301可以通过第二信道发送第二发射机配置352，其中第二信道为控制信道。举例而言，第一装置301被实现在终端侧，第二装置302被实现在网络侧，第二信道可以为物理上行链路控制信道(physical uplink control channel，PUCCH)。举例而言，第一装置301被实现在网络侧，第二装置302被实现在终端侧，第二信道可以为物理下行链路控制信道(physical downlink control channel，PDCCH)。举例而言，第一装置301和第二装置302都被实现在终端侧，第一信道可以为物理边链路控制信道(physical sidelink control channel，PSCCH)。
相应地，第二装置302接收(354)第二发射机配置352。在一些示例中，第二发射机配置352包括第二处理块配置。可选地，第二发射机配置352还可以包括第二信道特性码字或第二信道感知掩码。
在一些实施例中，第二发射机配置352可以包括第二信道特性码字。在一例中，第二装 置302可以将第二信道特性码字用于后续的数据处理过程。在另一例，第二装置302可以基于第二信道特性码字来确定信道长期特征，并将所确定的信道长期特征用于后续的数据处理过程，可理解，第二信道特性码字可以作为信道长期特征的先验信息。可理解，基于第二信道特性码字的信道长期特征可以是第二装置302处的输入之一，其可以为收发机联合训练得到的隐变量，基于此可以调整第二装置302的神经网络的输出。
在一些实施例中，响应于接收到第二发射机配置352，第二装置302可以将原有的第一发射机配置更新为第二发射机配置352。并且，第二发射机配置352可以被用于后续的信号传输。例如，在接收到第二发射机配置352之后，针对另一待发送数据，第二装置302可以基于第二发射机配置352和另一待发送数据生成另一信号，并经由第一信道发送至第一装置301。可理解，针对另一待发送数据的信号传输过程与图3中的过程300类似，这里不再重复。
可理解，通过结合图3的实施例，第二装置302处的发射机配置能够与第一装置301的联合训练而被实时更新，例如第二装置302处的第一发射机配置可以被更新为第二发射机配置，这样能够实时地调整第二装置302的输出能力。可见，在第二装置处的发射机配置能够基于第二装置与第一装置之间的环境变化而自适应地调整，从而增强了不同环境的泛华能力。在此过程中，第一信道的信道特性可以认为是联合训练中所得到的用于描述信道统计特性的隐变量。本公开的实施例中通过处理块配置定义了处理粒度，能够在多个物理资源上进行联合收发，提高了收发机的性能，并且能够减低模型的复杂度和提高模型的可扩展性。
图4示出了根据本公开的一些实施例的通信过程400的一个示意图。如图4所示，包括AI发射机410和AI发射机420。示例性地，AI发射机410可以包括前述如图3所示的第二装置302，AI接收机420可以包括前述图3所示的第一装置301。
AI发射机410的输入可以包括第一发射机配置和待发送数据，输出可以包括信号，例如符号流。该信号可以经由信道401被传输到AI接收机420，其中信道401可以为数据信道。AI接收机420可以接收经历信道401后的信号，输出可以包括数据421和信道长期特征422。信道长期特征422可以被输入配置生成算法402，以得到(即输出)第二发射机配置423，例如在图4中的第二发射机配置423包括处理块配置和信道特性码字。并且第二发射机配置423可以例如经由控制信道被发送至AI发射机410。可选地，第二发射机配置423中的处理块配置可以用4bit信令表示，第二发射机配置423中的信道特性码字可以用32bit表示。
可理解，信道长期特征422是AI接收机420的输出之一，并且可选地，其后续可以作为AI发射机410的输入之一。可见，信道长期特征422属于收发机联合训练得到的隐变量。
图5示出了根据本公开的一些实施例的通信过程500的另一个示意图。如图5所示，包括AI发射机510和AI发射机520。示例性地，AI发射机510可以包括前述如图3所示的第二装置302，AI接收机520可以包括前述图3所示的第一装置301。
AI发射机510的输入可以包括第一发射机配置和待发送数据，输出可以包括信号，例如符号流。该信号可以经由信道501被传输到AI接收机520，其中信道501可以为数据信道。AI接收机520可以接收经历信道501后的信号，输出可以包括数据521和信道长期特征522。信道长期特征522可以被输入配置生成算法502，以得到(即输出)第二发射机配置523，例如在图5中的第二发射机配置523包括处理块配置和信道感知掩码。并且第二发射机配置523可以例如经由控制信道被发送至AI发射机510。可选地，第二发射机配置523中的处理块配置可以用4bit信令表示，第二发射机配置523中的信道感知掩码可以用26bit表示。作为一 例，第二发射机配置523中的处理块配置可以指示(1,1)，第二发射机配置523中的信道感知掩码可以指示[(2,5,8),(3,6,9)]。
图6A示出了根据本公开的一些实施例的对应星座图配置600的示意图。结合图5，可以假设AI发射机510从AI接收机520接收第二发射机配置523，其中处理块配置可以指示(1,1)，信道感知掩码可以指示[(2,5,8),(3,6,9)]。
具体而言，由于第二发射机配置523中的处理块配置指示(1,1)，即处理块的大小为1个RB×1个OFDM符号，而1个RB包括12个子载波，因此在AI发射机510处的后续处理中，共有12个星座图。参照图6A，任一列包括的子载波索引为0至11的12个子载波对应于12个星座图，并且图6A中任一列的12个星座图可以是在12个非规则星座图的基础上结合信道感知掩码所确定的。第二发射机配置523中的信道感知掩码[(2,5,8),(3,6,9)]可以对应子载波索引(2,5,8)以及符号索引(3,6,9)，因此AI发射机510可以在信道感知掩码所指示的位置处使用预定调制方式(如QAM)，而在其余位置处使用非规则星座图。如图6A所示，在信道感知掩码所指示的位置，即图6A中以粗体下划线示出的子载波索引(2,5,8)以及符号索引(3,6,9)处，通过竖直线表示QAM调制方式，而在其余位置通过非竖直点线表示非规则星座图。
图6B示出了根据本公开的一些实施例的12个非规则星座映射表650的示例。如图6B所示，通过第一行的索引0-11示出的是12个非规则星座映射表。可理解，非规则星座映射表是非规则星座图的数值化表示，如图6B中包括两路：同相(in-phase，I)和正交(quadrature，Q)。本公开的实施例中，非规则星座映射表和非规则星座图在一些场景下可以被交替使用，本公开对此不限定。具体而言，可以在图6B所示的12个非规则星座映射表的基础上，来确定如图6A中任一列所示的12个星座图。以图6A中符号索引为0的第一列为例，由于第二发射机配置523中的信道感知掩码指示的子载波索引包括2，5和8，因此将子载波索引2，5和8对应位置处通过竖直线表示QAM调制方式，而在其余位置通过非竖直点线表示非规则星座图。
如上在结合图3的实施例中，第一发射机配置可以被预先配置或存储在第二装置302中，示例性地，第二装置302可以被实现在网络侧或终端侧。下面结合图7至图10描述确定第一发射机配置的一些可能的实现方式。
图6C示出了根据本公开的一些实施例的块误码率性能660的示意图。图中的横轴表示信号强度(Es)与噪声功率谱密度(N0)之间的比值，纵轴表示块误码率(block error ratio，BLER)。假设信号的发射机在抽头延迟线(tapped delay line TDL)-C300，速度为100千米每小时(km/h)的情形下被设计。在图6C中，线661表示在理想情况下的基线，用于性能参考。在图6C的示例中，验证信道满足TDL-C30和速度3km/h。
线662表示在TDL-C300和速度100km/h(C300，v100)的条件下训练得到的BLER。在验证信道下其存在信道失配的问题。可以看出，线662远离基线661，因此性能较差。线663表示在TDL-C30和速度3km/h(C30，v3)的条件下训练得到的BLER。可以看出，线663靠近基线661，因此性能较佳。
线664表示采用本公开的实施例的信道感知掩码的方案，在C300，v100的条件下训练得到的BLER。可以看出，相比于线662，采用本公开的实施例的方案能够获得0.6dB的增益，因此能够缓解信道失配的问题。并且尽管该方案在C300，v100条件下训练得到，但是如图 6C所示，线664与C30，v3条件下得到的线663较为接近，因此采用本公开的实施例的方案不需要因条件改变而重新进行训练，能够减小训练成本，降低因重新训练导致的时延开销。

具体而言，在过程730之前，在终端设备220建立连接时，网络设备210能够获取终端设备220的设备能力，并且网络设备210可以基于该设备能力生成第一发射机配置。举例而言，网络设备210能够基于网络设备210的环境的默认配置以及终端设备220的设备能力，来生成第一发射机配置。示例性地，网络设备210通过RRC重配置信令将第一发射机配置发送到终端设备220。
