Description

通信方法、装置、系统和可读存储介质 技术领域
本申请涉及无线通信领域，并且更具体地，涉及通信方法、装置、系统和可读存储介质。
背景技术
在车到一切(vehicle-to-everything，V2X)通信中，定义了两种空口，第一种为终端设备与接入网设备或基站之间的通信链路或者空口，一般称为Uu口，在Uu口传输的数据链路被称为上行链路(简称为上行)和下行链路(简称为下行)(uplink and donwlink)，Uu口定义了终端设备和基站之间的通信协议。第二种叫近距离通信(proximity communication 5，PC5)，在PC5口传输的数据链路被称为侧行链路(sidelink，SL)(简称为侧行)，PC5口定义了终端设备和终端设备之间的通信协议。在sidelink通信中，规定了终端设备的两种模式(mode)，即mode-1和mode-2。它们之间的区别是，处于mode-1的终端设备，在通信时，资源调度由基站进行；而处于mode-2的终端设备，在通信时，资源调度由终端设备进行。例如，基站预先配置资源池或者标准预定义资源池，终端设备在通信时，从该资源池中选择资源。
在新空口(new radio，NR)系统中，V2X通信也考虑支持多种子载波间隔，以支持不同类型的通信场景。比如在高速场景下，为了对抗多普勒频移，可以采用比较大的子载波间隔(例如60kHz)；而对于一般的广播场景，可以采用较低的子载波间隔(例如15kHz)从而容忍更大的多径时延。如何在支持多种子载波间隔，即子载波间隔可变，的情况下，保证自动增益控制(automatic gain control，AGC)的有效执行，是一个亟待解决的问题。

另外，在本申请实施例中，“示例的”一词用于表示作例子、例证或说明。本申请中被描述为“示例”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用示例的一词旨在以具体方式呈现概念。
本申请实施例中，“的(of)”，“相应的(corresponding，relevant)”和“对应的(corresponding)”有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。
本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请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，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请实施例既可以应用于时分双工(time division duplex，TDD)的场景，也可以适用于频分双工(frequency division duplex，FDD)的场景。
本申请实施例既可以应用在传统的典型网络中，也可以应用在未来的以UE为中心(UE-centric)的网络中。UE-centric网络引入无小区(Non-cell)的网络架构，即在某个特定的区域内部署大量 小站，构成一个超级小区(Hyper cell)，每个小站为Hyper cell的一个传输点(Transmission Point,TP)或TRP，并与一个集中控制器(controller)相连。当UE在Hyper cell内移动时，网络侧设备时时为UE选择新的sub-cluster(子簇)为其服务，从而避免真正的小区切换，实现UE业务的连续性。其中，网络侧设备包括无线网络设备。
本申请实施例中部分场景以无线通信网络中NR网络的场景为例进行说明，应当指出的是，本申请实施例中的方案还可以应用于其他无线通信网络中，相应的名称也可以用其他无线通信网络中的对应功能的名称进行替代。
本申请实施例中的网络设备可以为具有无线收发功能的设备或可设置于该设备的芯片，可以部署在无线接入网中为终端设备提供无线通信服务。该设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission and reception point，TRP或者transmission point，TP)等，还可以为5G，如，NR，系统中的gNB，或，传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(DU，distributed unit)等，或者，为车载设备、可穿戴设备或未来演进的PLMN网络中的网络设备等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括射频单元(radio unit，RU)。多个DU可以由一个CU集中控制。CU实现gNB的部分功能，DU实现gNB的部分功能，CU和DU可以根据无线网络的协议层划分，例如分组数据汇聚层协议(packet data convergence protocol，PDCP)层及以上协议层的功能设置在CU，PDCP以下的协议层，例如无线链路控制(radio link control，RLC)层和介质接入控制(medium access control，MAC)层等的功能设置在DU。又例如，CU实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，DU实现无线链路控制(radio link control，RLC)、媒体接入控制(media access control，MAC)和物理(physical，PHY)层的功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令或PHCP层信令，也可以认为是由DU发送的，或者，由DU+RU发送的。可以理解的是，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，CU可以划分为接入网RAN中的网络设备，也可以将CU划分为核心网CN中的网络设备，在此不做限制。
或者，CU可以划分为控制面(CU-CP)和用户面(CU-UP)。其中CU-CP负责控制面功能，主要包含RRC和PDCP-C。PDCP-C主要负责控制面数据的加解密，完整性保护，数据传输等中的一项或多项。CU-UP负责用户面功能，主要包含SDAP和PDCP-U。其中SDAP主要负责将核心网的数据进行处理并将flow映射到承载。PDCP-U主要负责数据面的加解密，完整性保护，头压缩，序列号维护，数据传输等中的一项或多项。其中CU-CP和CU-UP通过接口(例如E1接口)连接。CU-CP通过接口(例如Ng接口)和核心网连接，通过接口(例如F1-C(控制面接口))和DU连接。CU-UP通过接口(例如F1-U(用户面接口))和DU连接。

在本申请实施例中，终端设备或网络设备包括硬件层、运行在硬件层之上的操作系统层，以及运行在操作系统层上的应用层。该硬件层包括中央处理器(central processing unit，CPU)、内存管理单元(memory management unit，MMU)和内存(也称为主存)等硬件。该操作系统可以是任意一种或多种通过进程(process)实现业务处理的计算机操作系统，例如，Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操作系统等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。并且，本申请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的程序，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的执行主体可以是终端设备或网络设备，或者，是终端设备或网络设备中能够调用程序并执行程序的功能模块。
另外，本申请的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于:磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，压缩盘(compact disc，CD)、数字通用盘(digital versatile disc，DVD)等)，智能卡和闪存器件(例如，可擦写可编程只读存储器(erasable programmable read-only memory，EPROM)、卡、棒或钥匙驱动器等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
车辆对其他设备(vehicle to everything,V2X)通信是车联网中实现环境感知、信息交互的重要关键技术，这里的其他设备可以是其他车辆、其他基础设施、行人、或终端设备等中的一项或多项。V2X通信可以看成是设备到设备(device to device，D2D)通信的一种特殊情形。车辆到车辆(vehicle to vehicle，V2V)之间的通信可以看成是V2X通信的一种特殊情形，通过车辆和车辆之间直接进行通信，可以实时地获取其他车辆的状态信息以及路面情况，从而更好地辅助车辆驾驶甚至实现自动驾驶。V2V之间的通信链路可以称为侧行链路(side link，SL)，侧行链路为终端设备和终端设备设备之间的通信直连链路。例如，可以车辆到车辆之间的通信等。直连链路可以理解为两个终端设备之间直接进行数据传输的链路，两个终端设备之间没有其他的网络节点。图1是V2V通信的一个典型场景的示意图。如图1所示，行驶中的车辆可以通过V2V通信来直接和附近的其他车辆交互信息。可以理解的是，本申请实施例提供的方法、装置，系统和可读存储介质，也可以应用于其他D2D通信网络，图1为D2D通信网络的一种示例，也可以认为是V2X网络的一种示例。
目前，V2X通信包含两种通信模式：第一种通信模式是基于网络设备(例如基站)调度的V2X通信，V2X用户(例如可以是车辆或者车载设备)根据网络设备的调度信息在被调度的时频资源上发送V2X通信的控制消息和数据。第二种通信模式是V2X用户在预配置的V2X通信资源池(或者也可以称为V2X资源集合)包含的可用时频资源中自行选择V2X通信所用的时频资源，并在所选择的资源上发送控制信息和数据。两种通信模式各有优缺点，可以灵活运用于各种不同的场景。
V2X通信的时频资源是基于V2X通信资源池来进行配置的。V2X通信资源池可以看作是用于V2X通信的时域资源和频率资源的集合。例如，对于时域资源，网络设备可以采用一个比特地图(bit map)并且周期性重复该比特地图来指示系统中所有时间单元，比如子帧或时隙，中可用于V2X通信的时间单元的集合。其中，一个子帧的时间长度可以为1ms，一个时隙的时间长度可以为0.5ms或者1ms或者其他长度(比如由子载波间隔决定)。图2是利用比特地图指示用于V2X通信的时隙的示意图。例如，可以利用比特位“1”指示某一个时隙用于V2X通信，利用比特位“0”指示某一个时隙不用于V2X通信。图2所示例子中的比特地图的长度为8比特。
对于V2X通信资源池的频率资源，网络设备可以将用于V2X通信的频段分成若干个子信道，每个子信道包含一定数量的资源块(resource block，RB)。子信道可以为频率资源调度的最小单元。图3是一例V2X通信资源池的时频资源示意图。如图3所示，利用比特位“1”指示某一时间单元，比如子帧或时隙，可用于V2X通信，利用比特位“0”指示某一个时间单元不用于V2X通信。另外网络设备会指示用于V2X通信的频率资源的第一个资源块的序号，该V2X通信资源池包含的总的子信道的数目N，每个子信道包含的资源块的数目n CH。V2X通信时数据或者控制信息传输一次可以占用一个或者多个子信道。需要理解的是，上述描述中的子帧为通信系统(例 如LTE)中定义的一种时间单位，一个子帧的时间长度为1ms，时隙也为通信系统(例如NR及LTE)中定义的一种时间单位，一个时隙的时间长度为0.5ms或者1ms或者其他长度(比如由子载波间隔决定)。示例的，在NR中，一个时隙可以包括14个符号，在LTE中，一个子帧可以包括14个符号，一个时隙可以包括7个符号(正常循环前缀CP)。
在V2X通信系统中，物理侧行控制信道(physical sidelink control channel，PSCCH)用于传输V2X通信中的控制信息，物理侧行共享信道(physical sidelink shared channel，PSSCH)用于传输V2X通信中的数据。前述控制信息用于接收端接收V2X通信时的数据。目前，比如但不限于LTE系统，PSCCH和PSSCH可以采用频分复用(frequency division multiplexing，FDM)的方式进行复用。图4-1是PSCCH和PSSCH采用频分复用的示意图。如图4-1所示，PSCCH和PSSCH的占用相同的时域资源，在频域上占据不同的子载波。
作为另外一种可能实现方式，PSCCH和PSSCH可以利用部分时分复用和部分频分复用的方式，图4-2是PSCCH和PSSCH采用部分频分复用和部分时分复用的示意图。如图4-2所示，一部分PSSCH与PSCCH占用相同的时域资源，在频域上占据不同的子载波，一部分PSSCH与PSCCH在时域上占据不同的时域资源。
在无线通信过程中，AGC是接收端根据平均或者峰值接收功率来动态地调整放大器的增益的操作，通过AGC可以使得接收端的相关电路能够在更大范围的输入信号下正常地工作。因此，在进行AGC之前，接收端会接收发送端发送的信号，并且根据所述信号的接收功率进行AGC。随后，接收端可以继续接收发送端发送的其他信号。也即，进行有效的AGC是接收端正确接收发送端所发信息的一个必要步骤。图5给出了一个用于AGC的无线传输的示意图，其中在无线传输开头的一部分可以用于接收端进行AGC，从而使得接收端能正确接收随后的无线传输。
当前V2X网络中，V2X传输时间单元，如子帧或时隙，的第一个符号用于AGC。
对于NR V2X网络，由于可以支持多种子载波间隔，包括15kHz，30kHz，60kHz等中的一项或多项。随着子载波间隔的增大，一个符号的持续时间会减少，例如15kHz时，一个符号持续时间大约是66.7微秒；30kHz时，一个符号持续时间是15kHz的一半，也即33.3微秒；60kHz时，一个符号持续时间是15kHz的四分之一，也即16.7微秒。其他子载波间隔以此类推。而AGC所需要的时间和接收信号的带宽相关，接收信号的带宽越大，AGC所需的时间越短；接收信号的带宽越小，AGC所需的时间越大。换言之，如果用于AGC的信号占据一个符号，那么随着子载波间隔的增大，AGC的持续时间会减小，所需要的接收信号的带宽也会越大，从而需要进一步考虑AGC对于V2X资源调度的影响。
有鉴于此，本申请实施例提供了一种通信方法，具体也可以称为频率资源的调度方法，以期在支持多种子载波间隔，即，子载波间隔可变的情况下，保证AGC的有效执行。在本申请实施例中，具体用于AGC的符号可以是V2X传输时间单元的第一个符号，或是前若干个符号。
为便于理解本申请实施例，首先结合图6和图7简单介绍适用于本申请实施例的通信系统。
图6是适用于本申请实施例的通信方法的通信系统100的示意图。如图6所示，该通信系统100包括四个通信设备，例如，网络设备110，终端设备121至123，其中，终端设备和终端设备可以通过D2D或者V2X的通信方式进行数据通信，网络设备110与终端设备121至123中的至少一个之间可以进行数据通信。对于终端设备121至123，两两之间形成的直连链路为SL。例如，终端设备121和123进行侧行控制信息和/或数据的传输时，可以通过本申请实施例的频率资源的调度方法进行承载侧行数据的频率资源的调度。
图7是适用于本申请实施例的通信方法的通信系统200的示意图。如图7所示，该通信系统200包括三个通信设备，例如，终端设备121至123，其中，终端设备和终端设备可以通过D2D或者V2X的通信方式进行数据通信。对于终端设备121至123，两两之间的链路为SL。例如，终端设备123和122之间进行侧行控制信息和/或数据的传输时，可以通过本申请实施例的频率资源的调度方法进行承载侧行数据的频率资源的调度。
应理解，图6和图7所示的各通信系统中还可以包括更多的网络节点，例如终端设备或网络设备，图6和图7所示的各通信系统中包括的网络设备或者终端设备可以是上述各种形式的网络设备或者终端设备。本申请实施例在图中不再一一示出。
下面结合图8-1，8-2，8-3和8-4详细说明本申请提供的通信方法，图8-1，8-2，8-3和8-4是本申请一个实施例的通信方法10的示意性交互图，该方法10可以应用在图1、图6和图7所示 的场景中，当然也可以应用在其他通信场景中，本申请实施例在此不作限制。
本申请实施例提供的通信方法，具体可以称为频率资源的调度方法，可以用于两个终端设备，比如终端设备A和终端设备B，之间的侧行通信。
应理解，在本申请实施例中，以终端设备和网络设备作为各个实施例的执行方法的执行主体为例，对各个实施例的方法进行说明。作为示例而非限定，执行方法的执行主体也可以是应用于终端设备的芯片和应用于基站的芯片。示例性的，方法10应用于V2X通信系统中时，该终端设备(比如，终端设备A和/或终端设备B)可以是V2X通信中的车辆、车载设备、手机终端等中的一项或多项。

S110，终端设备A向终端设备B发送第一调度信息和侧行数据，所述第一调度信息包括频率资源信息，所述频率资源信息指示用于承载侧行数据的频率资源，所述频率资源信息以子信道为单位(即，第一频率资源信息对应的频率资源以子信道为最小频域调度单元)且所述频率资源信息所指示的被调度带宽不小于第一自动增益控制AGC所需的最小带宽，所述第一AGC所需的最小带宽为所述侧行数据的接收端执行AGC所需的最小带宽，所述第一AGC所需的最小带宽与所述侧行数据所对应的第一子载波间隔具有第一对应关系；
相应的，终端设备B接收来自终端设备A的所述第一调度信息，并根据所述第一调度信息接收来自所述终端设备A的侧行数据；
可选的，该第一调度信息可以承载在物理侧行控制信息(PSCCH)中。
其中，终端设备B根据所述第一调度信息接收来自所述终端设备A的侧行数据，具体可以包括：终端设备B根据所述频率资源信息接收来自所述终端设备A的侧行数据。
其中，终端设备A利用所述频率资源发送所述侧行数据。
可选的，侧行数据可以承载在物理侧行数据信道(PSSCH)中。
其中，所述PSCCH和PSSCH可以采用部分频分复用和部分时分复用的方式映射在时频资源上，如图9-1所示。终端设备A可以发送PSCCH和PSSCH，终端设备B可以根据预先定义的规则在V2X通信资源池所包含的时频资源上盲检PSCCH，终端设备B检测到PSCCH后，根据PSCCH携带的第一调度信息，确定PSSCH的频率资源信息和时域资源信息中的一项或多项，并基于所述PSSCH的频率资源信息和时域资源信息中的一项或多项对相应的PSSCH进行接收和/或处理。例如，如图9-1所示，可以规定PSCCH总是位于子信道的最低的4个RB，假设资源池包含10个子信道，编号为0-9，并且当前被调度的PSSCH占据子信道3-5。接收端首先在前述10个子信道中的每个子信道的前4个RB盲检PSCCH，检测到信道3上有PSCCH，并根据PSCCH承载的第一调度信息获知PSSCH承载在子信道3-5上，进而在子信道3-5对PSSCH进行接收和/或处理。
在S110之前，该方法还可以包括：
S100，终端设备A获得所述频率资源信息，所述频率资源信息指示用于承载侧行数据的频率资源；
基于不同的V2X的通信模式，即，终端设备所处的不同通信模式，S100可以有不同的方式，具体可以包括三种方式。
其中，方式一，适用于工作在模式1(mode-1)的终端设备，如图8-2所示，S100可以至少包括S1000，其中：
S1000，终端设备A接收来自网络设备的第二调度信息，其中，所述第二调度信息包括频率资源信息，所述频率资源信息指示用于承载侧行数据的频率资源，所述频率资源信息以子信道为单位且所述频率资源信息所指示的被调度带宽不小于第一自动增益控制AGC所需的最小带宽，所述第一AGC所需的最小带宽为所述侧行数据的接收端执行AGC所需的最小带宽，所述第一AGC所需的最小带宽与所述侧行数据所对应的第一子载波间隔具有第一对应关系；

可选的，所述第二调度信息可以承载在下行控制信息(downlink control information，DCI)中，其中，DCI携带在物理下行控制信道(PDCCH)中；或者，第二调度信息可以承载在物理下行共享信道(PDSCH)中。
可选的，在所述网络设备发送所述第二调度信息之前，可以确定发给所述终端设备A的第二 调度信息。
进一步的，终端设备A可以根据所述第二调度信息向所述终端设备B发送第一调度信息并根据所述频率资源信息向终端设备B发送所述侧行数据，即，执行步骤S110。
可以理解的是，第一调度信息所指示的频率资源信息(简称第一频率资源信息)和第二调度信息所指示的频率资源信息(简称第二频率资源信息)虽然都是用于承载终端设备A向终端设备B发送的侧行数据的，但二者可以采用相同的形式或不同的形式，比如，如后续将详细描述的，第一频率资源信息可以包括实际调度的频率资源的信息或指示实际调度的频率资源的信息与第一AGC所需的最小带宽所占子信道个数的差值，第二频率资源信息可以包括实际调度的频率资源的信息或指示实际调度的频率资源的信息与第一AGC所需的最小带宽所占子信道个数的差值，在第一频率资源信息和第二频率资源信息采用不同的形式时，终端设备A可以将所接收到第二频率资源信息转换为待发送给终端设备B的第一频率资源信息。
方式二，适用于工作在模式2(mode-2)的终端设备，如图8-3所示，S100可以至少包括S1010，其中：
S1010，所述终端设备A接收来自终端设备C的第三调度信息，其中，所述第三调度信息包括频率资源信息，所述频率资源信息指示用于承载侧行数据的频率资源，所述频率资源信息以子信道为单位且所述频率资源信息所指示的被调度带宽不小于第一自动增益控制AGC所需的最小带宽，所述第一AGC所需的最小带宽为所述侧行数据的接收端执行AGC所需的最小带宽，所述第一AGC所需的最小带宽与所述侧行数据所对应的第一子载波间隔具有第一对应关系；
相应的，终端设备C向所述终端设备A发送所述第三调度信息。
可选的，所述第三调度信息可以承载在侧行控制信息(downlink control information，SCI)中，其中，SCI携带在物理侧行控制信道(PSCCH)中；或者，第三调度信息可以承载在物理侧行共享信道(PSSCH)中。
可选的，在所述终端设备C发送所述第三调度信息之前，可以确定发给所述终端设备A的第三调度信息。
进一步的，终端设备A可以根据所述第三调度信息向所述终端设备B发送第一调度信息并根据所述频率资源信息向终端设备B发送所述侧行数据，即，执行步骤S110。
可以理解的是，第一调度信息所指示的频率资源信息(简称第一频率资源信息)和第三调度信息所指示的频率资源信息(简称第三频率资源信息)虽然都是用于承载终端设备A向终端设备B发送的侧行数据的，但二者可以采用相同的形式或不同的形式，比如，如后续将详细描述的，第一频率资源信息可以包括实际调度的频率资源的信息或指示实际调度的频率资源的信息与第一AGC所需的最小带宽所占子信道个数的差值，第三频率资源信息可以包括实际调度的频率资源的信息或指示实际调度的频率资源的信息与第一AGC所需的最小带宽所占子信道个数的差值，在第一频率资源信息和第三频率资源信息采用不同的形式时，终端设备A可以将所接收到第三频率资源信息转换为待发送给终端设备B的第一频率资源信息。
方式三，适用于工作在模式2(mode-2)的终端设备，如图8-4所示，S100可以至少包括S1020，其中：
S1020，所述终端设备A自行确定第一调度信息，其中，所述第一调度信息包括频率资源信息，所述频率资源信息指示用于承载侧行数据的频率资源，所述频率资源信息以子信道为单位且所述频率资源信息所指示的被调度带宽不小于第一自动增益控制AGC所需的最小带宽，所述第一AGC所需的最小带宽为所述侧行数据的接收端执行AGC所需的最小带宽，所述第一AGC所需的最小带宽与所述侧行数据所对应的第一子载波间隔具有第一对应关系；
进一步的，终端设备A向所述终端设备B发送第一调度信息并利用所述频率资源信息对应的频率资源向终端设备B发送所述侧行数据，即，执行步骤S110。
以上方法10中，所述第一对应关系为至少一个AGC所需的最小带宽与多个子载波间隔之间的多个对应关系中的一个，所述至少一个AGC所需的最小带宽包括所述第一AGC所需的最小带宽，所述子载波间隔包括所述第一子载波间隔。
其中，AGC所需的最小带宽与子载波间隔之间的对应关系可以为一对多，多对一，或者，一对一，可以依据具体协议或应用场景或设计需求确定，在此不予限定。
可选的，所述第一AGC所需的最小带宽包括M个资源块RB，M为正整数，即，第一AGC所需的最小带宽可以以资源块RB为单位。
可选的，所述子信道的带宽不大于所述第一AGC所需的最小带宽。这样，可以避免在第一AGC所需的最小带宽较大的情况下，以子信道为最小调度单元进行频域资源的调度，所造成的频域资源的浪费。此外，子信道的带宽可以为协议预定义的值，也可以通过信令进行配置。该配置可以是直接配置子信道的带宽，或者，可以通过子信道的带宽与其他参数的对应关系及所述其他参数的配置来实现。其中，子信道的带宽与其他参数的对应关系可以为协议预定义的，或是，通过信令配置的，在此不予限定。其中，其他参数可以包括终端设备所在载波的带宽或者终端设备所在的带宽部分(bandwidth part，BWP)的带宽或者是终端设备的侧行BWP带宽等中的一项或多项。
下表1示出了至少一个AGC所需的最小带宽与多个子载波间隔之间的多个对应关系的一个举例，可以理解的是，AGC所需的最小带宽与子载波间隔之间的对应关系可以满足以下所示对应关系中的一个。下表中的某子载波间隔所对应的AGC所需的最小带宽也可以为其他值，比如将以下不同的AGC所需的最小带宽替换为第一值或第二值等不同的取值，相应的，子载波间隔也可以替换为第一子载波间隔或第二子载波间隔等不同的取值。

上表中的对应关系的一项或多项还可以形成其他的对应关系表，即，形成一张或多张表，来体现AGC所需的最小带宽与子载波间隔之间的对应关系。此外，可以理解的是，AGC所需的最小带宽与子载波间隔之间的对应关系可以通过前述的表的形式表现，或者，还可以为以公式或字符串等其他形式表现，在此不予限定。
可选的，以上对应关系可以存储于以上方法10中的发送端和/或接收端，即，预定义在发送端和/或接收端的，其中，发送端可以为上述方法中提及的网络设备，终端设备C，终端设备A中的一个或多个(在本申请实施例中的其他部分也适用)，接收端可以为上述方法中提及的终端设备A，终端设备B中的一个或多个(在本申请实施例中的其他部分也适用)。这样，发送端可以根据侧行数据所对应的子载波间隔及所存储的子载波间隔与AGC所需的最小带宽之间的对应关系获知该子载波间隔所对应的第一AGC所需的最小带宽，进而，可以确定用于承载侧行数据的频率资源的带宽，以使得侧行数据的被调度带宽不小于第一自动增益控制AGC所需的最小带宽。这样可以保证侧行数据的接收端有效的执行AGC。而接收端可以根据侧行数据所对应的子载波间隔及所存储的子载波间隔与AGC所需的最小带宽之间的对应关系获知该子载波间隔所对应的第一AGC所需的最小带宽。
可选的，以上对应关系也可以进行配置，比如由发送端向接收端进行配置，或是，由主控制端向所述发送端和/或接收端进行配置，比如，通过RRC信令，MAC层信令或物理层信令中的一项或多项进行配置。具体的，可以对以上对应关系中的各项进行索引或是直接将当前侧行数据所对应的AGC所需的最小带宽包括在用于所述配置的信息中，比如，通过RRC信令，MAC层信令 或物理层信令中的一项或多项携带所述用于配置的信息，从而对当前侧行数据所对应的AGC所需的最小带宽进行直接的指示，这样，接收端可以无需结合子载波间隔来获得当前侧行数据所对应的AGC所需的最小带宽。
可选的，前述方法10中所述的频率资源信息可以包括实际调度的频率资源的信息，所述实际调度的频率资源信息为实际调度的频率资源所包括的子信道的个数N，所述N为正整数。或者，所述频率资源信息可以指示实际调度的频率资源的信息与第一AGC所需的最小带宽所占子信道个数的差值，所述实际调度的频率资源的信息为实际调度的频率资源所包括的子信道的个数N，所述N为正整数，比如，所述频率资源信息可以满足实际调度的频率资源的信息与第一AGC所需的最小带宽所占子信道个数的差值的函数，该函数可以为所述差值，或者，所述差值+1。指示差值，可以进一步降低调度信息的开销，使用差值+1，可以进一步避免出现实际调度的频率资源的信息与第一AGC所需的最小带宽所占子信道个数相同时在调度信息中频率资源信息所对应的域的值为0的情况。这样，可以避免域的值为0，对译码或是解扰造成的干扰。
以频率资源信息包括实际调度的频率资源的信息为例，假设子信道的带宽n subCH＝2(RB)，当前侧行数据对应的第一AGC所需的最小带宽n AGC＝12(RB)(根据表1，当前侧行数据对应的子载波间隔为60kHz或120kHz)，而终端设备A当前V2X数据传输所需的带宽为15RB。则可以调度V2X的传输带宽，即侧行数据(PSSCH)的被调度带宽为8个子信道，并且侧行控制信息(PSCCH)在频域上也可以跨多个子信道。图9-2和图9-3为该V2X资源调度的示意图，其中，图9-2中PSCCH/DMRS(解调参考信号)在第一个符号中传输，图9-3中PSCCH/DMRS在第一个符号中不传输，第一个符号用于AGC，PSCCH占据4个子信道，PSSCH占据8个子信道。可以看到，在该示例中，子信道的带宽远小于所述第一AGC所需的最小带宽，相较于将子信道的带宽设置为等于所述第一AGC所需的最小带宽，调度15RB需要2个子信道，会有9个RB被浪费，该示例采用的子信道的带宽小于所述第一AGC所需的最小带宽的设置，可以有效的避免频率资源的浪费。以图9-2或图9-3为例，可以规定PSCCH的带宽是8个RB，并且其起始RB总是位于子信道的最低RB，假设资源池包含20个子信道，编号为0～19，每个子信道带宽2RB，并且此次被调度的PSSCH占据子信道2～9，接收端可以先在前述20个子信道中的每个子信道的最低RB为起始盲检PSCCH，检测到信道2上有PSCCH并且该PSCCH横跨子信道2～5，进而根据PSCCH中的指示，如调度信息，获知PSSCH占据子信道2～9，进而在子信道2～9上对前述PSSCH进行(后续)接收和/或处理。
再以频率资源信息指示实际调度的频率资源的信息与第一AGC所需的最小带宽所占子信道个数的差值为例，记频率资源信息所指示的子信道的数目为N sched_i，记实际需要调度的子信道的数目为N sched，当前侧行数据对应的第一AGC所需的最小带宽为n AGC，子信道的带宽为n subCH，则
Figure PCTCN2019101112-appb-000001
图10-1给出了这种差值指示方式的一个示意图。其中，左图中，假设n AGC＝10RB、n subCH＝4RB、实际需要调度的子信道数目N sched＝3(如图中阴影部分)，则需要额外指示的信道的数目N sched_i＝0；右图中，假设n AGC＝10RB、n subCH＝6RB、实际需要调度的子信道数目N sched＝4(如图中阴影部分)，则需要额外指示的信道的数目N sched_i＝2。也就是，发送端，如网络设备，终端设备C，终端设备A中的一个或多个，可以通过频率资源信息指示额外的信道数目N sched_i。对于接收端，如终端设备A，终端设备B中的一个或多个，可以根据被指示的子信道的数目N sched_i，配置或者预配置或者协议预定义的AGC所需的最小带宽n AGC以及配置或者预配置或者协议预定义的子信道带宽n subCH，得出实际调度的子信道的数目
Figure PCTCN2019101112-appb-000002
可以看出，采用这种差值的指示方法可以降低指示开销。
另一方面，也可以对上述方法进行适当改动，从而避免出现所指示的子信道数目为0，比如前述的所述频率资源信息满足实际调度的频率资源的信息与第一AGC所需的最小带宽所占子信道个数的差值的函数，该函数可以为所述差值+1。具体地，记频率资源信息指示的子信道的数目为N sched_i，记实际需要调度的子信道的数目为N sched，当前侧行数据对应的第一AGC所需的最小带宽为n AGC，子信道的带宽为n subCH，则

图10-2给出了这种差值指示方式的另一个示意图，其中，左图中，假设n AGC＝10RB、n subCH＝4RB、实际需要调度的子信道数目N sched＝3(如图中阴影部分)时，则需要额外指示的信道的数目N sched_i＝1；右图中，假设n AGC＝10RB、n subCH＝6RB、实际需要调度的子信道数目N sched＝4(如图中阴影部分)时，则需要 额外指示的信道的数目N sched_i＝3。也就是，发送端，如网络设备，终端设备C，终端设备A中的一个或多个，可以通过频率资源信息指示额外的信道数目N sched_i。对于接收端，如终端设备A，终端设备B中的一个或多个，可以根据被指示的子信道的数目N sched_i，配置或者预配置或者标准预定义的AGC所需带宽n AGC以及配置或者预配置或者标准预定义的子信道带宽n subCH，得出实际调度的子信道的数目
