例如，gNB为终端设备提供NR的控制面和/或用户面的协议和功能，并将终端设备接入5G核心网。
例如，ng-eNB为终端设备提供演进型通用陆地无线接入(evolved universal terrestrial radio access，E-UTRA)的控制面和/或用户面的协议和功能，并将终端设备接入5G核心网。
下面以接入网设备为gNB为例介绍接入网设备的一种可能的分割结构，对于其他类型的接入网设备同样适用。
请参阅图2，下一代核心网201中的核心网设备与下一代无线接入网202中的gNB203以及gNB204通过NG接口连接,gNB203与gNB204之间通过Xn接口连接。
下面以gNB1为例介绍gNB的一种可能的分割结构。gNB按照逻辑功能可以切分为一个或多个集中单元(central unit,CU)(这里称为gNB-CU205)、一个或多个分布式单元(distributed unit,DU)(这里称为gNB-DU206)。其中，gNB-CU205和gNB-DU206在物理上可以是分离的，也可以部署在一起，本申请实施例对此不做具体限定。gNB-CU205和gNB-DU206之间可以通过接口连接。例如，gNB-CU205和gNB-DU206之间可以通过F1接口 连接。
gNB-CU205和gNB-DU206的切分可以按照无线网络的协议层切分。例如，将无线资源控制(radio resource control，RRC)、服务数据适应协议(service data adaptation protocol，SDAP)以及分组数据汇聚协议(packet data convergence protocol，PDCP)层的功能部署在gNB-CU205。无线链路控制(radio link control，RLC)层、媒体访问控制(media access control，MAC)层以及物理(physical,PHY)层的功能部署在gNB-DU206。例如，对于NR通信系统，gNB-CU205包括gNB203的RRC层、SDAP层和PDCP层，gNB-DU206包括gNB203的RLC层、MAC层和PHY层。
可以理解的是，上述按照无线网络的协议层划分gNB-CU205和gNB-DU206的方式仅仅是一种举例。实际应用中，gNB-CU205和gNB-DU206也可以按照其他的方式进行划分，本申请实施例对此不做具体限定。
进一步的，gNB-CU205可以包括一个或多个CU控制面(CU control plane，CU-CP)(这里称为gNB-CU-CP2051)和一个或多个CU用户面(CU user plane，CU-UP)(这里称为gNB-CU-UP2052)。图2中以gNB-CU205包括一个gNB-CU-CP2051和一个gNB-CU-UP2052为例进行说明。gNB-CU-CP2051和gNB-CU-UP2052可以理解为是对gNB-CU205从逻辑功能的角度的一种划分。gNB-CU-CP2051和gNB-CU-UP2052可以根据无线网络的协议层划分。例如，RRC层和PDCP层控制面的功能设置在gNB-CU-CP2051中，SDAP层的功能和PDCP层用户面的功能设置在gNB-CU-UP2052中。
gNB-CU-CP2051和gNB-CU-UP2052之间可以通过接口相连。例如，如图2所示，gNB-CU-CP2051和gNB-CU-UP2052通过E1接口连接。gNB-CU-CP2051和gNB-DU206之间可以通过F1的控制面接口(F1-C)连接。gNB-CU-UP2052和gNB-DU206之间可以通过F1的用户面接口(F1-U)连接。
可以理解的是，上述按照无线网络的协议层划分gNB-CU-CP2051和gNB-CU-UP2052的方式仅仅是一种举例。实际应用中，gNB-CU-CP2051和gNB-CU-UP2052也可以按照其他的方式进行划分，本申请实施例对此不做具体限定。
DAM207主要负责数据收集、机器学习(machine learning，ML)模型训练、ML模型生成、ML模型更新、ML模型分发等功能。进一步的，gNB-CU、gNB-DU、gNB-CU-CP或者gNB-CU-UP可以分别通过G1接口和数据分析管理(data analysis and management，DAM207)单元连接。
可选的，DAM207作为gNB-CU205、gNB-DU206、gNB-CU-CP2051或gNB-CU-UP2052的内部功能。在该实现方式下，不存在G1接口。或者，当DAM207作为gNB-CU205的内部功能时，G1接口可以是DAM207在gNB-CU205中与gNB-CU205的其他功能之间的接口，对外不可见。或者，当DAM207作为gNB-DU206的内部功能时，G1接口可以是DAM207在gNB-DU206中与gNB-DU206的其他功能之间的接口，对外不可见。或者，当DAM207作为gNB-CU-CP2051的内部功能时，G1接口可以是DAM207在gNB-CU-CP2051中与gNB-CU-CP2051的其他功能之间的接口，对外不可见。或者，当DAM207作为gNB-CU-UP2052的内部功能时，G1接口可以是DAM207在gNB-CU-UP2052中与 gNB-CU-UP2052的其他功能之间的接口，对外不可见。
下面介绍本申请所涉及到的技术术语。
邻居小区：两个小区之间不存在其他小区时，这两个小区为相邻的小区。其中一个小区可以称为另一小区的邻居小区。邻居小区可以简称邻区。

请参阅图3A，图3A为本申请实施例通信方法的一个实施例示意图。在图3A中，通信方法包括：
301、第一接入网设备确定第一信息。
第一信息用于指示在第一时间内第一小区的邻居小区的调度信息。第一小区为终端设备接入或驻留的小区。第一信息用于指示第一时间内邻居小区的发射信号的发射状况。
第一时间指邻居小区在未来的调度时间。第一时间可以称为未来调度时间或分析目标时间。第一时间包括一个或多个调度时间单元。可以理解的是，第一信息用于指示预测的在第一时间内第一小区的邻居小区的调度信息；或者，第一信息用于指示未来的在第一时间内第一小区的邻居小区的调度信息；或者，第一信息用于指示估计的在第一时间内第一小区的邻居小区的调度信息。
例如，调度时间单元为传输时间间隔(transmission time interval，TTI)或子帧。TTI是指传输块集(transport block set,TBS)的到达时间间隔，也就是传输一个传输块大小所需的时间。那么，第一时间包括邻居小区在未来的一个或多个TTI，或者，一个或多个子帧。
一个TTI在时域上最小为1个子帧的长度。信号调制是以正弦波周期为单位的，每个正弦波周期称为一个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，而经过调制后的OFDM符号则称为符号。每个子帧在时域上占用14个符号，即1ms(毫秒)。因此，一个TTI占用14个符号。可选的，在一个调度周期内，每个调度时间单元都有唯一的标识，用于标识该调度时间单元。
需要说明的是，调度时间单元对应的调度时间标识可以直接表示。例如，用TTI-1、TTI-2分别表示第一调度时间单元、第二调度时间单元。或者，调度时间标识可以间接表示。例如，通过调度时间单元所在的时域位置和/或频域位置进行表示；或者，通过调度时间单元相对于系统帧号的偏移进行表示；或者，通过调度时间单元所在的子载波位置和/或符号位置进行表示。调度时间标识也可以由其他方式进行表示，本申请实施例对此不做具体限定。
例如，如图3B所示，小区1为UE1接入的小区。小区2为小区1的邻居小区。当前时刻为t0，第一时间为时刻t0之后的一个或多个TTI。第一信息包括用于指示预测的在时刻t0之后的一个或多个TTI内的小区2调度信息。
可选的，第一信息包括以下至少一项：
1、邻居小区在第一时间内是否有发射信号的信息；
邻居小区在第一时间内是否有发射信号的信息用于指示邻居小区在第一时间内是否有 发射信号，下面示出几种可能的指示方式。
一、由上述描述可知，第一时间包括一个或多个调度时间单元，每个调度时间单元有对应的调度时间标识。下面示出通过每个调度时间单元对应的调度时间标识指示每个调度时间单元上是否有发射信号的两种可能的实现方式。
a、邻居小区在第一时间内是否有发射信号的信息包括调度时间标识，则表示该调度时间标识对应的调度时间单元上有发射信号。
例如，第一时间包括邻居小区的未来调度的6个TTI，调度时间标识分别为TTI-1至TTI-6。邻居小区在第一时间内是否有发射信号的信息包括TTI-1、TTI-3和TTI-5，则表示TTI-1、TTI-3和TTI-5分别所对应的调度时间单元上有发射信号。
b、邻居小区在第一时间内是否有发射信号的信息包括调度时间标识，则表示该调度时间标识对应的调度时间单元上没有发射信号。
例如，第一时间包括邻居小区未来调度的6个TTI，调度时间标识分别为TTI-1至TTI-6。邻居小区在第一时间内是否有发射信号的信息包括TTI-2、TTI-4和TTI-6，则表示TTI-2、TTI-4和TTI-6分别所对应的调度时间单元上没有发射信号。
二、邻居小区在第一时间内是否有发射信号的信息包括第一时间包括的一个或多个调度时间单元中每个调度时间单元对应的信号指示。每个调度时间单元对应的信号指示用于指示该每个调度时间单元上是否有发射信号。
每个调度时间单元对应的信号指示的具体指示方式包括以下任一种：
a、若调度时间单元对应的信号指示的取值为“1”，则表示在该调度时间单元上有发射信号。若调度时间单元对应的信号指示的取值为“0”，则表示在该调度时间单元上没有发射信号。
b、若调度时间单元对应的信号指示的取值为“0”，则表示在该调度时间单元上有发射信号。若调度时间单元对应的信号指示的取值为“1，则表示在该调度时间单元上没有发射信号。
c、若调度时间单元对应的信号指示的取值为“开(on)”，则表示在该调度时间单元上有发射信号。若调度时间单元对应的信号指示的取值为“关(off)”，则表示在该调度时间单元上没有发射信号。
d、若调度时间单元对应的信号指示的取值为“关(off)”，则表示在该调度时间单元上有发射信号。若调度时间单元对应的信号指示的取值为“开(on)”，则表示在该调度时间单元上没有发射信号。
e、若调度时间单元对应的信号指示的取值为“真(true)”，则表示在该调度时间单元上有发射信号。若调度时间单元对应的信号指示的取值为“假(false)”，则表示在该调度时间单元上没有发射信号。
f、若调度时间单元对应的信号指示的取值为“假(false)”，则表示在该调度时间单元上有发射信号。若调度时间单元对应的信号指示的取值为“真(true)”，则表示在该调度时间单元上没有发射信号。
三、邻居小区在第一时间内是否有发射信号的信息包括调度时间单元对应的信号指示， 则表示该调度时间单元上有发射信号。
例如，第一时间包括邻居小区未来调度的6个TTI，调度时间标识分别为TTI-1至TTI-6。邻居小区在第一时间内是否有发射信号的信息包括TTI-1对应的信号指示、TTI-3对应的信号指示以及TTI-5对应的信号指示，则表示TTI-1、TTI-3和TTI-5分别对应的调度时间单元上有发射信号。
四、邻居小区在第一时间内是否有发射信号的信息包括调度时间单元对应的信号指示，则表示该调度时间单元上没有发射信号。
例如，第一时间包括邻居小区未来调度的6个TTI，调度时间标识分别为TTI-1至TTI-6。邻居小区在第一时间内是否有发射信号的信息包括TTI-2对应的信号指示、TTI-4对应的信号指示以及TTI-6对应的信号指示，则表示TTI-2、TTI-4和TTI-6上分别对应的调度时间单元没有发射信号。
五、邻居小区在第一时间内是否有发射信号的信息包括第一时间包括的一个或多个调度时间单元中每个调度时间单元对应的比特位。每个调度时间单元对应的比特位用于指示该调度时间单元上是否有发射信号。
例如，第一时间包括M个调度时间单元。M个调度时间单元对应M个比特位。M为大于或等于1的整数。M个比特为通过位图(bitmap)的方式表示。即该位图包括M个比特位。M个比特位中每个比特位的取值用于指示该每个比特位对应的调度时间单元上是否有发射信号。
例如，M个比特位中每个比特位的取值为“1”，则表示该每个比特位对应的调度时间单元上有发射信号。M个比特位中每个比特位的取值为“0”，则表示该每个比特位对应的调度时间单元上没有发射信号。
例如，M个比特位中每个比特位的取值为“0”，则表示该每个比特位对应调度时间单元上有发射信号。M个比特位中每个比特位的取值为“1”，则表示该每个比特位对应的调度时间单元上没有发射信号。
由上述示例可知，邻居小区在第一时间内是否有发射信号的信息可以为指示信息(例如，信号指示、或比特位)，也可以为调度时间标识，还可以为其他类型的信息，具体本申请不做限定。
2、邻居小区在第一时间内的发射信号的信号强度；
第一时间包括一个或多个调度时间单元。该一个或多个调度时间单元中部分或全部调度时间单元上有发射信号。第一信息包括该部分或全部调度时间单元上分别对应的发射信号的信号强度。
例如，第一时间包括邻居小区未来调度的6个TTI，调度时间标识分别为TTI-1至TTI-6。其中，TTI-1至TTI-4分别对应的调度时间单元上有发射信号。TTI-5和TTI-6分别对应的调度时间单元上没有发射信号。那么，第一信息包括TTI-1至TTI-4分别对应的调度时间单元上分别对应的发射信号的信号强度。
可选的，信号强度为功率。例如，100毫瓦。或者，信号强度为分贝毫瓦(decibel relative to one milliwatt，dBm)。其中，dBm与功率的关系为：x＝10*log 10(P/1mW)。x为信号强度 以dBm为单位的具体表示值。P为信号强度以功率为单位的具体表示值。log 10(a)指以10为底数对a求对数。1mW指1毫瓦。
可选的，信号强度为绝对信号强度，或者为相对信号强度。
例如，绝对信号强度为该部分或全部调度时间单元上分别对应的发射信号的信号强度。例如，TTI-1对应的调度时间单元上的发射信号的信号强度为-10dBm。即TTI-1对应的调度时间单元上的发射信号的绝对信号强度为-10dBm。
例如，相对信号强度为该部分或全部调度时间单元上分别对应的发射信号的绝对信号强度分别与参考信号的绝对信号强度的相对值。例如，参考信号可以为信道状态信息参考信号(channel state information reference signal，CSI-RS)；或者，参考信号可以为小区特定的参考信号(cell-specific reference signal，CRS)；或者，信道状态信息同步信号块(channel state information synchronization signal block，CSI-SSB)。
参考信号的绝对信号强度是固定的。第一接入网设备可以通过该部分或全部调度时间单元上分别对应的发射信号的绝对信号强度分别与参考信号的绝对信号强度的相对值表示该部分或全部调度时间单元上分别对应的发射信号的相对信号强度。
例如，参考信号的绝对信号强度为-10dBm。TTI-1的发射信号的相对信号强度为-1dBm，则表示TTI-1对应的调度时间单元上的发射信号的绝对信号强度与参考信号的绝对信号强度的相对值为-1dBm。即TTI-1对应的调度时间单元上的发射信号的绝对信号强度为-11dBm，或者为-9dBm。
需要说明的是，相对信号强度的正负需要预先定义。
例如，相对信号强度为正，表示在参考信号的绝对信号强度上增加该相对信号强度的绝对值。相对信号强度为负，表示在参考信号的绝对信号强度上减少该相对信号强度的绝对值。
又例如，相对信号强度为正，表示在参考信号的绝对信号强度上减少该相对信号强度的绝对值。相对信号强度为负，表示在参考信号的绝对信号强度上增加该相对信号强度的绝对值。
3、邻居小区的标识信息；
邻居小区的标识信息用于指示第一信息包括的调度信息为邻居小区的调度信息。
例如，邻居小区的标识信息包括邻居小区的新无线小区全球标识(NR cell global identifier，NCGI)、或者、邻居小区的物理小区标识(physical cell identifier，PCI)、或者、邻居小区的SSB索引值(SSB index)。
4、邻居小区在第一时间内的调度信息的置信度；
置信度用于指示邻居小区在第一时间内的调度信息的可信程度。
第一时间为邻居小区在未来的一段时间，可以称为未来调度时间。因此，置信度表征预测的邻居小区在未来调度时间内的调度信息的预测准确度。
例如，置信度采用百分比表示。例如，置信度可以表示为60％、70％、85％等。置信度的数值越高，表示邻居小区在第一时间内的调度信息的可信程度越高。
例如，置信度采用“高”、“中”和“低”表示，以表示邻居小区在第一时间内的调度信息的 可信程度。
需要说明的是，若第一信息只包括置信度，那么第一接入网设备可以通过其他消息或信息向终端设备反馈邻居小区在第一时间内的调度信息。而该置信度用于指示第一接入网设备在其他消息或信息发送的邻居小区在第一时间内的调度信息的可信程度。后续终端设备可以结合置信度确定是否参考该邻居小区在第一时间内的调度信息确定目标CQI索引值，具体请参阅后文步骤303的相关介绍。
5、第一时间的信息；
第一时间的信息用于指示邻居小区在第一时间内的调度信息对应的分析目标时间。即指示该调度信息是预测的在分析目标时间内邻居小区的发射信号的状况。
第一时间的信息包括第一起始时间。第一起始时间为邻居小区在第一时间内的调度信息对应的预测起始时间。
一种可能的实现方式中，第一时间的信息包括第一结束时间。第一结束时间为邻居小区在第一时间内的调度信息对应的预测结束时间。
例如，当前时间为2020年11月9日16:00。第一信息包括的调度信息的预测起始时间为2020年11月9日16：01，预测结束时间为2020年11月9日16：30。也就是说第一信息包括的调度信息是预测的在2020年11月9日16：01至2020年11月9日16：30之间的时间段内邻居小区的调度信息。第一信息包括的调度信息用于指示在2020年11月9日16：01至2020年11月9日16：30之间的时间段内邻居小区的发射信号的状况。
另一种可能的实现方式中，终端设备与第一接入网设备之间可以预先约定第一接入网设备每次向终端设备发送的邻居小区的预测调度信息对应的预测时长。也就是终端设备通过第一起始时间和预测时长可以确定第一结束时间。
例如，预测时长为30分钟。第一起始时间为2020年11月9日16：01。终端设备可以确定第一信息包括的调度信息的预测结束时间为2020年11月9日16：30。那么可知，第一信息包括的调度信息为预测的在2020年11月9日16：01至2020年11月9日16：30之间的时间段内邻居小区的调度信息。第一信息包括的调度信息用于指示在2020年11月9日16：01至2020年11月9日16：30之间的时间段内邻居小区的发射信号的状况。
6、产生第一信息的时间信息。
产生第一信息的时间信息包括第一接入网设备产生邻居小区在第一时间内的调度信息的产生时间。例如，产生第一信息的时间信息包括时间戳，通过时间戳指示产生邻居小区在第一时间内的调度信息的产生时间。
例如，第一接入网设备接收到第二接入网设备的两份预测调度信息。第一接入网设备部通过时间戳确定第一份预测调度信息的产生时间比第二份预测调度信息的产生时间更早。第二份预测调度信息是最新产生的，更能反映邻居小区的最新调度情况。因此，第一接入网设备决定使用第二份预测调度信息。第二接入网设备为管理邻居小区的接入网设备。
可选的，第一接入网设备为管理第一小区的接入网设备。也就是说由终端设备接入或驻留的接入网设备确定第一信息，并向终端设备发送第一信息，以提高第一信息的发送效率。
本实施例中，第一接入网设备确定第一信息的具体确定方式有多种，下面通过举例说明两种可能的实现方式。
1、第一接入网设备接收来自第二接入网设备的第三信息，并根据第三信息确定第一信息。第二接入网设备为管理邻居小区的接入网设备。第三信息用于指示邻居小区在第四时间内的调度信息。第四时间为邻居小区未来的调度时间，且第四时间包括第一时间。即第三信息用于指示邻居小区在未来的调度时间内的调度信息。具体请参阅图4所示的实施例的相关介绍。
2、第一接入网设备接收第二接入网设备的第四信息，并根据第四信息确定第一信息。第四信息用于指示邻居小区在第三时间内的调度信息。第三时间为邻居小区的历史调度时间。即第四信息用于指示邻居小区在历史调度时间内的调度信息。具体请参阅前述图5所示的实施例的相关介绍。
302、第一接入网设备向终端设备发送第一信息。
其中，第一信息用于终端设备确定目标CQI索引值。
终端设备接入或驻留在第一小区。对于终端设备来说，第一小区的邻居小区的发射信号是干扰信号。第一接入网设备可以向终端设备发射第一信息。这样，终端设备可以结合第一信息确定目标CQI索引值。目标CQI索引值也可以称为预测CQI索引值，或未来CQI索引值，或估计CQI索引值，在此不做限定。即通过目标CQI索引值反馈邻居小区在未来的调度时间(关于未来的调度时间请结合后文步骤303理解)内的发射信号的状况。
本实施例中，可选的，第一接入网设备通过下行控制信息(downlinkcontrolinformation，DCI)、媒体接入控制控制元素(media accesscontrol control element，MAC CE)、或无线资源控制(radio resource control，RRC)消息向终端设备发送的第一信息。可选的，当第一接入网设备为DU并且通过RRC消息向终端设备发送第一信息时，第一接入网设备可以先将第一信息发送给管理该第一接入网设备的CU。然后，CU通过RRC消息将该第一信息发送给终端设备。
可选的，本实施例还包括步骤302a，且步骤302a在步骤303之前执行。
302a、第一接入网设备向终端设备发送第二信息。
第二信息包括以下至少一项：CQI索引值类型指示、第二时间的信息。
CQI索引值类型指示用于指示终端设备上报的CQI索引值的类型。
本实施例中，CQI索引值类型包括CQI索引值和目标CQI索引值。CQI索引值为终端设备根据已有技术确定的。目标CQI索引值是终端设备基于邻居小区在未来调度时间内的调度信息确定的。
本实施例中，CQI索引值类型指示用于指示终端设备上报目标CQI索引值；或者，CQI索引值类型指示用于指示终端设备上报目标CQI索引值和CQI索引值。
第二时间的信息用于指示终端设备基于第二时间的信息确定目标CQI索引值。第二时间为第一时间中的部分时间。例如，第一时间包括TTI-1至TTI-6分别对应的调度时间单元。第二时间的信息包括TTI-5对应的调度时间单元。
具体的，第一接入网设备指示终端设备上报目标CQI索引值时，第一接入网设备还可 以向终端设备发送第二时间的信息。第二时间的信息用于指示终端设备确定第二时间对应的目标CQI索引值。例如，第一时间包括TTI-1至TTI-6分别对应的调度时间单元。第二时间的信息包括TTI-5对应的调度时间单元。那么，第二时间的信息用于指示终端设备预测TTI-5对应的CQI索引值。
本实施例中，第一接入网设备可以通过同一信息或同一消息向终端设备发送步骤302a的第二信息和步骤302的第一信息。或者，第一接入网设备也可以通过不同信息或不同消息向终端设备发送步骤302a的第二信息和步骤302的第一信息，具体本申请不做限定。例如，第一接入网设备通过RRC消息向终端设备发送第一信息。第一接入网设备通过主信息块(master information block，MIB)消息或系统信息块(system information block，SIB)消息向终端设备发送第二信息。
需要说明的是，步骤302和步骤302a之间没有固定的执行顺序。例如，可以先执行步骤302，再执行步骤302a；或者可以先执行步骤302a，再执行步骤302；或者依据情况同时执行步骤302a和步骤302，具体本申请不做限定。
303、终端设备根据第一信息确定目标CQI索引值。
一种可能的实现方式中，终端设备在第一时刻t0接收到第一信息，终端设备根据第一信息包括的邻居小区在第一时间内是否有发射信号的信息确定邻居小区在第二时刻t1有发射信号。然后，终端设备根据第一信息包括的邻居小区在第一时间内的发射信号的信号强度确定在第二时刻t1邻居小区的发射信号的信号强度。其中，t1等于t0+△t，△t大于0，△t是第一接入网设备和终端设备的约定时间。t0大于或等于0。然后，终端设备根据邻居小区在第二时刻t1的发射信号的信号强度计算第二时刻t1对应的SINR1，并根据SINR与CQI之间的映射关系以及第二时刻t1对应的SINR1确定目标CQI索引值。
例如，如图3B所示，终端设备接收到的参考信号的信号强度为S1。终端设备根据第一信息确定在时刻t1的干扰信号的预测值为0，则SINR1＝S1/N0。N0为噪声的信号强度。然后，终端设备根据SINR与CQI之间的映射关系(具体可以以映射表的形式表示)，确定SINR1对应的目标CQI索引值。t1等于t0+△t，△t大于0，△t是第一接入网设备和终端设备的约定时间。例如，△t为4个TTI。
又例如，终端设备接收到的参考信号的信号强度为S1。终端设备根据第一信息确定在时刻t1的干扰信号的预测值为S3，则SINR1＝S1/(S3+N0)。N0为噪声的信号强度，S3大于0。然后，终端设备根据SINR与CQI之间的映射关系(具体可以以映射表的形式表示)，确定SINR1对应的目标CQI索引值。t1等于t0+△t，△t大于0，△t是第一接入网设备和终端设备的约定时间。例如，△t为4个TTI。
另一种可能的实现方式中，在上述步骤302a中终端设备还接收到第二信息。终端设备根据第二信息确定基于第二时间的信息计算目标CQI索引值。终端设备根据第一信息包括的邻居小区在第一时间内的发射信号的信号强度确定邻居小区在第二时间的发射信号的信号强度。然后，终端设备根据邻居小区在第二时间的发射信号的信号强度计算第二时间对应的SINR，并根据SINR与CQI之间的映射关系以及第二时间对应的SINR计算目标CQI索引值。
例如，第一信息包括TTI-1至TTI-6分别对应的调度时间单元上分别对应的发射信号的信号强度。第二时间包括TTI-5对应的调度时间单元。那么终端设备从第一信息确定TTI-5对应的调度时间单元上的发射信号的信号强度。然后，终端设备根据TTI-5对应的调度时间单元上的发射信号的信号强度计算TTI-5对应的SINR，并根据SINR与CQI之间的映射关系以及TTI-5对应的SINR确定目标CQI索引值。
在上述任一种实现方式中，终端设备还可以根据第一信息的置信度确定第一信息的可信程度，以决定是否采用第一信息包括的调度信息。终端设备还可以根据第一时间的信息和产生第一信息的时间信息确定是否采用第一信息包括的调度信息。
可选的，第二信息指示终端设备上报CQI索引值和目标CQI索引值。那么，终端设备还可以计算当前时刻t0对应的CQI索引值，并向第一接入网设备发送该CQI索引值和目标CQI索引值。
例如，如图3B所示，终端设备接收到的参考信号的信号强度为S1。终端设备在时刻t0接收到的干扰信号(例如，邻居小区的发射信号(包括邻居小区的数据信号和控制信号等))的信号强度为S2。N0为噪声的信号强度。那么，终端设备确定SINR2＝S1/(S2+N0)。然后，终端设备根据SINR与CQI之间的映射关系确定CQI索引值，再向第一接入网设备发送CQI索引值。
304、终端设备向第一接入网设备发送目标CQI索引值。
其中，目标CQI索引值用于第一接入网设备为终端设备选择调制编码方案。
例如，第一接入网设备在时刻t1根据目标CQI索引值为终端设备选择调制编码方案。第一接入网设备通过该调制编码方案为终端设备传输数据。目标CQI索引值表征是终端设备在时刻t1的无线信道状态，第一接入网设备根据目标CQI索引值为终端设备选择的调制编码方案能够匹配终端设备在时刻t1的无线信道状态，从而提高通信传输性能。
例如，如图3B所示，在时刻t0，邻居小区的发射信号为S2。而在时刻t1，邻居小区的发射信号为零。因此，UE1向第一接入网设备反馈的时刻t0对应的CQI索引值并无法反映UE1在时刻t1的无线信道状况。UE1在时刻t1没有来自邻居小区的干扰信号。UE1通过预测的在时刻t1对应的目标CQI索引值应当更大。因此，第一接入网设备可以采用码率更高的调制编码方案为终端设备传输数据，从而提升通信传输性能。
为了使得第一接入网设备确定终端设备是否支持CQI索引值的预测，终端设备可以上报终端设备的能力信息。可选的，本实施例还包括步骤305。
305、终端设备向第一接入网设备发送终端设备的能力信息。
终端设备的能力信息用于指示终端设备支持CQI索引值的预测。终端设备支持CQI索引值的预测也可以称为终端设备支持CQI预测。
一种可能的实现方式中，步骤305可以理解为：终端设备主动向第一接入网设备上报能力信息。能力信息用于指示终端设备支持CQI索引值的预测，以便于第一接入网设备执行上述步骤301至步骤302。
例如，步骤305中的能力信息承载于UE辅助信息(UE assistance information)消息。或者，步骤305中的能力信息承载于UE能力信息(UE capability information)消息。实现 终端设备向第一接入网设备上报终端设备的能力信息。
本实施例中，第一接入网设备也可以主动向终端设备请求能力信息，以确定终端设备是否支持CQI索引值的预测。
可选的，本实施例还包括步骤306。步骤306可以在步骤305之前执行。
306、第一接入网设备向终端设备发送针对终端设备的能力请求，能力请求用于请求终端设备是否支持CQI索引值的预测。
例如，上述步骤306中的能力请求为UE能力查询(UE capability enquiry)消息。第一接入网设备通过UE能力查询消息向终端设备请求终端设备是否支持CQI索引值的预测。
基于步骤306，那么步骤305可以理解为：终端设备响应该第一接入网设备发送的能力请求。终端设备向第一接入网设备反馈的能力信息。
本申请实施例中，终端设备接收来自第一接入网设备的第一信息。第一信息用于指示在第一时间内第一小区的邻居小区的调度信息。第一小区为终端设备接入或驻留的小区。然后，终端设备根据第一信息确定目标CQI索引值，再向第一接入网设备发送目标CQI索引值。由此可知，本申请实施例的技术方案，终端设备可以获取第一信息。该第一信息表征终端设备在未来调度时间内的无线信道状况。然后，终端设备再结合第一信息确定目标CQI索引值，并向第一接入网设备发送该目标CQI索引值。这样第一接入网设备可以结合该目标CQI索引值确定终端设备的调制编码方案。然后，第一接入网设备通过该调制编码方案为终端设备传输数据，从而提高通信传输性能。
上述图3A所示的实施例的步骤305和步骤306示出了第一接入网设备确定终端设备支持CQI索引值的预测的一种可能的实现方式。在实际应用中，第一接入网设备可以通过其他方式确定终端设备支持CQI索引值的预测，具体本申请不做限定。例如，第一接入网设备从其他设备(例如，核心网设备、网络控制设备、或其他接入网设备等)获取终端设备的能力信息。可选的，核心网设备(或网络控制设备、或其他接入网设备等)向第一接入网设备发送终端设备的能力信息。
上述图3A所示的实施例中，步骤302a的第二信息与步骤302的第一信息可以是同一信息。在该实现方式中，第一信息包括上述步骤301中示出的内容和步骤302a中示出的内容。
请参阅图4，图4为本申请实施例通信方法的另一个实施例示意图。在图4中，通信方法包括：
401、第二接入网设备确定第三信息。
第二接入网设备为管理邻居小区的接入网设备。第三信息用于指示邻居小区在第四时间内的调度信息。第四时间为邻居小区在未来的调度时间。即第三信息用于指示预测的(或者、估计的、或者、未来的)邻居小区在第四时间内的调度信息。第四时间包括第一时间。
例如，第二接入网设备通过ML模型预测或估计邻居小区在第四时间内的调度信息。
可选的，第二接入网设备可以先获取邻居小区的历史调度信息。然后，第二接入网设备结合历史调度信息和ML模型预测或估计邻居小区在第四时间内的调度信息。
具体的，第二接入网设备包括DAM，关于DAM的相关介绍请参阅图2的相关介绍。 第二接入网设备的DAM预先配置有训练好的机器学习(machine learning，ML)模型。第二接入网设备可以通过该ML模型确定上述邻居小区在第四时间内的预测调度信息。
例如，该ML模型可以是亚力克斯网络(AlexNet)。第二接入网设备将邻居小区的历史调度信息输入上述ML模型，该ML模型即可输出邻居小区在第四时间内的调度信息，作为该邻居小区对应的预测调度信息。
如果要求第三信息的精确度较高，则第二接入网设备可以使用能够产生更高精确度的ML模型进行运算，以向第一接入网设备提供精确度较高的第三信息。
本实施例中，可选的，第三信息包括以下至少一项：

2、邻居小区在第四时间内的发射信号的信号强度；
3、邻居小区的标识信息；
4、邻居小区在第四时间内的调度信息的置信度；
5、第四时间的信息；
6、产生第三信息的时间信息。
第三信息与前述图3A所示的实施例中的步骤301的第一信息类似，具体可以参阅前述图3A所示的实施例中的步骤301的相关介绍，这里不再赘述。
402、第二接入网设备向第一接入网设备发送第三信息。
一种可能的实现方式中，步骤402理解为：邻居小区的发射信号对于终端设备来说干扰信号，第二接入网设备可以主动向第一接入网设备发送第三信息。这样，第一接入网设备可以根据第三信息确定第一信息，并向终端设备下发第一信息。
另一种可能的实现方式中，本实施例还包括步骤401a。步骤401a可以在步骤401之前执行。
401a、第一接入网设备向第二接入网设备发送第三信息请求。
第三信息请求用于向第二接入网设备请求第三信息。
可选的，第三信息请求包括以下任一项：
1、邻居小区的标识信息；
第一接入网设备通过邻居小区的标识信息告知第二接入网设备第一接入网设备请求获取的第三信息的对象。例如，例如，邻居小区的标识信息包括邻居小区的NCGI，或者，邻居小区的PCI，或者邻居小区的SSB索引值。
2、第四时间的信息；
第四时间的信息与前述第一时间的信息类似，具体可以参阅前述相关介绍，这里不再赘述。
第四时间也可以称为分析目标时间，第一接入网设备通过第四时间的信息告知第二接入网设备第一接入网设备期望或偏向(preferred)获取邻居小区在具体时间范围(即第四时间)的预测调度信息。
3、第一获取时间；
第一获取时间用于指示第一接入网设备期望或偏向(preferred)获取到第三信息的时间。
第一获取时间可以理解为第一接入网设备期望或偏向获取到邻居小区在第四时间内的调度信息的最晚时间。如果第二接入网设备不能在第一获取时间之内向第一接入网设备发送邻居小区在第四时间内的调度信息，则第二接入网设备向第一接入网设备发送第一错误响应。第一错误响应用于指示第二接入网设备无法向第一接入网设备发送邻居小区在第四时间内的调度信息。
4、第一周期性指示信息；
第一周期性指示信息用于指示第二接入网设备周期性向第一接入网设备发送第三信息。
可选的，第一周期性指示信息用于指示第二接入网设备周期性向第一接入网设备发送不同未来调度时间内邻居小区的预测调度信息。
例如，第一周期性指示信息指示第二接入网设备每隔20分钟向第一接入网设备发送邻居小区的预测调度信息。例如，第二接入网设备在2020年11月20日16:00向第一接入网设备发送预测的邻居小区在2020年11月20日16:01至2020年11月20日16:20之间的预测调度信息。第二接入网设备在2020年11月20日16:20向第一接入网设备发送预测的邻居小区在2020年11月20日16:21至2020年11月20日16:40之间的邻居小区的预测调度信息。
需要说明的是，当第三信息包括第一周期性指示信息时，第一信息还包括第一周期时间。例如，20分钟(min)，即第二接入网设备每隔20分钟向第一接入网设备发送预测调度信息。
5、期望精确度。
期望精确度用于指示第一接入网设备期望获取的第三信息的精确度。例如，期望精确度为“低”或“高”。
如果期望精确度为“高”，则第二接入网设备使用能够产生更高精确度的ML模型进行运算，以向第一接入网设备提供精确度较高的预测调度信息。
在该实现方式中，基于步骤401a，步骤402可以理解为第二接入网设备响应步骤401a的第三信息请求，向第一接入网设备反馈的第三信息。

需要说明的是，当第一小区的邻居小区有多个时，第一接入网设备可以根据管理多个邻居小区的第二接入网设备分别发送的第三信息确定第一信息。
例如，第一小区包括邻居小区1和邻居小区2。管理邻居小区1的接入网设备发送的第三信息包括：TTI-1对应的调度时间单元上邻居小区的发射信号的信号强度为A；TTI-2对应的调度时间单元上邻居小区的发射信号的信号强度为B；TTI-3对应的调度时间单元上 邻居小区的发射信号为C。管理邻居小区2的接入网设备发送的第三信息包括：TTI-1对应的调度时间单元上邻居小区的发射信号的信号强度为D；TTI-2对应的调度时间单元上邻居小区的发射信号的信号强度为E；TTI-3对应的调度时间单元上邻居小区的发射信号为F。
对于终端设备来说，邻居小区1的发射信号和邻居小区2的发射信号均为干扰信号。那么，第一接入网设备可以确定：TTI-1对应的调度时间单元上邻居小区的发射信号的信号强度为A+D、TTI-2对应的调度时间单元上邻居小区的发射信号的信号强度为B+E、以及TTI-3对应的调度时间单元上邻居小区的发射信号的信号强度为C+F。
其中，A，B，C，D，E和F均大于或等于0。即第一信息包括：TTI-1对应的调度时间单元上邻居小区的发射信号的信号强度为A+D、TTI-2对应的调度时间单元上邻居小区的发射信号的信号强度为B+E、以及TTI-3对应的调度时间单元上邻居小区的发射信号的信号强度为C+F。

b、邻居小区在第三时间内是否有发射信号的信息包括调度时间标识，则表示该调度时间标识对应的调度时间单元上没有发射信号。
例如，第三时间包括邻居小区历史调度的6个TTI，调度时间标识分别为TTI-1至TTI-6。邻居小区在第三时间内是否有发射信号的信息包括TTI-2、TTI-4和TTI-6，则表示TTI-2、TTI-4和TTI-6分别对应的调度时间单元上没有发射信号。
二、邻居小区在第三时间内是否有发射信号的信息包括第三时间包括的一个或多个调度时间单元中每个调度时间单元对应的信号指示。每个调度时间单元对应的信号指示用于指示该每个调度时间单元上是否有发射信号。每个调度时间单元对应的信号指示的具体指示方式请参阅前述图3A所示的实施例中的相关介绍，这里不再赘述。
三、邻居小区在第三时间内是否有发射信号的信息包括调度时间单元对应的信号指示，则表示该调度时间单元上有发射信号。
例如，第三时间包括邻居小区历史调度的6个TTI。邻居小区在第三时间内是否有发射信号的信息包括TTI-1对应的信号指示、TTI-3对应的信号指示以及TTI-5对应的信号指示，则表示TTI-1、TTI-3和TTI-5分别对应的调度时间单元上有发射信号。
四、邻居小区在第三时间内是否有发射信号的信息包括调度时间单元对应的信号指示，则表示该调度时间单元上没有发射信号。
例如，第三时间包括邻居小区的历史调度的6个TTI。邻居小区在第三时间内是否有 发射信号的信息包括TTI-2对应的信号指示、TTI-4对应的信号指示以及TTI-6对应的信号指示，则表示TTI-2、TTI-4和TTI-6分别对应的调度时间单元上没有发射信号。
五、邻居小区在第三时间内是否有发射信号的信息包括第三时间包括的一个或多个调度时间单元中每个调度时间单元对应的比特位。每个调度时间单元对应的比特位用于指示该调度时间单元上是否有发射信号。每个调度时间单元对应的比特位的指示方式请参阅前述图3A所示的实施例中的相关介绍，这里不再赘述。
2、邻居小区在第三时间内的发射信号的信号强度；
第三时间包括一个或多个调度时间单元。该一个或多个调度时间单元中部分或全部调度时间单元上有发射信号。第三信息包括该部分或全部调度时间单元上的发射信号的信号强度。信号强度的表示形式请参阅前述图3A所示的实施例中的相关介绍，这里不再赘述。
3、邻居小区的标识信息；
邻居小区的标识信息请参阅前述图3A所示的实施例中的相关介绍，这里不再赘述。
4、第三时间的信息；
第三时间的信息用于指示第三信息包括的调度信息对应的统计时间。第三时间也可以称为分析目标历史时间。即第三信息包括的调度信息是统计的在分析目标历史时间内邻居小区的调度信息，用于指示在分析目标历史时间内邻居小区的发射信号的状况。
第三时间的信息包括第二起始时间。第二起始时间为邻居小区在第三时间内的调度信息对应的统计起始时间。
一种可能的实现方式中，第三时间的信息包括第二结束时间。第二结束时间为邻居小区在第三时间内的调度信息对应的统计结束时间。
例如，当前时间为2020年11月9日16:00。第四信息包括的调度信息的统计起始时间为2020年11月9日15:30，以及统计结束时间为2020年11月9日15:59。也就是说第四信息包括的调度信息是统计的在2020年11月9日15:30至2020年11月9日15:59之间的时间段内邻居小区的调度信息。第四信息包括的调度信息用于指示在2020年11月9日15:30至2020年11月9日15:59之间的时间段内邻居小区的发射信号的状况。
另一种可能的实现方式中，第一接入网设备与第二接入网设备之间可以预先约定第二接入网设备每次向第一接入网设备发送的邻居小区的历史调度信息对应的统计时长。也就是第一接入网设备通过第二起始时间和统计时长确定第二结束时间。
例如，统计时长为30分钟。当前时间为2020年11月9日16:30。第二起始时间为2020年11月9日15:30。第一接入网设备根据第二起始时间和统计时长确定第四信息包括的调度信息的预测结束时间为2020年11月9日16:00。那么可知，第四信息包括的调度信息为统计的在2020年11月9日15:30至2020年11月9日16:00之间的时间段内邻居小区的调度信息。第四信息包括的调度信息用于指示在2020年11月9日15:30至2020年11月9日16:00之间的时间段内邻居小区的发射信号的状况。
5、产生第四信息的时间信息。
产生第四信息的时间信息包括第二接入网设备产生邻居小区在第三时间内的调度信息的产生时间。例如，产生第四信息的时间信息包括时间戳，通过时间戳指示产生邻居小区 在第三时间内的调度信息的产生时间。
例如，第一接入网设备接收到第二接入网设备的两份历史调度信息。第一接入网设备通过时间戳确定第一份历史调度信息的产生时间比第二份历史调度时间的产生时间更早。第二份历史调度时间是最新产生的，更能反映邻居小区的最新历史调度情况。因此，第一接入网设备可以使用第二份历史调度信息预测邻居小区在第一时间内的调度信息。
502、第二接入网设备向第一接入网设备发送第四信息。
一种可能的实现方式中，步骤502可以理解为：终端设备接入或驻留在第一小区。对于终端设备来说，第一小区的邻居小区的发射信号是干扰信号。第二接入网设备可以主动向第一接入网设备发送第四信息。这样第一接入网设备可以结合第四信息确定第一信息，以便于后续方案的实施。
另一种可能的实现方式中，本实施例还包括步骤501a，且步骤501a在步骤501之前执行。
501a、第一接入网设备向第二接入网设备发送第四信息请求。
第四信息请求用于向第二接入网设备请求第四信息。
可选的，第四信息请求包括以下任一项：
1、邻居小区的标识信息；
关于邻居小区的标识信息请参阅前述图3A所示的实施例中的相关介绍，这里不再赘述。
2、第三时间的信息；
第三时间的信息请参阅前述步骤501中的相关介绍，这里不再赘述。
3、第二获取时间；
第二获取时间用于指示第一接入网设备期望或偏向(preferred)获取到第四信息的时间。
具体的，第二获取时间可以理解为第一接入网设备期望或偏向获取到邻居小区在第三时间内的调度信息的最晚时间。如果第二接入网设备不能在第二获取时间之内向第一接入网设备发送邻居小区在第三时间内的调度信息，则第二接入网设备向第一接入网设备发送第二错误响应。第二错误响应用于指示第二接入网设备无法向第一接入网设备发送邻居小区在第三时间内的调度信息。
4、第二周期性指示信息。
第二周期性指示信息用于指示第二接入网设备周期性向第一接入网设备发送第四信息。
可选的，第二周期性指示信息用于指示第二接入网设备周期性向第一接入网设备发送不同历史调度时间内邻居小区的历史调度信息。
例如，第二周期性指示信息指示第二接入网设备每隔30分钟向第一接入网设备发送邻居小区的历史调度信息。例如，第二接入网设备在2020年11月20日16:00向第一接入网设备发送统计的邻居小区在2020年11月20日15:01至2020年11月20日15:30之间的历史调度信息。第二接入网设备在2020年11月20日16:30向第一接入网设备发送统计的邻居小区在2020年11月20日15:31至2020年11月20日16:00之间的历史调度信息。
需要说明的是，当第四信息包括第二周期性指示信息时，第四信息还包括第二周期时 间。例如，30分钟，即第二接入网设备每隔30分钟向第一接入网设备发送邻居小区的历史调度信息。
503、第一接入网设备根据第四信息确定第一信息。
第一信息的相关介绍请参阅前述图3A所示的实施例中的相关介绍，这里不再赘述。
例如，第一接入网设备将第四信息作为ML模型的输入参数，得到ML模型的输出参数。即将ML模型的输出作为邻居小区在第一时间内的调度信息，以得到第一信息。
结合上述图2所示，第一接入网设备为gNB1，gNB1集成有DAM。DAM预先配置有经过训练的ML模型。第一接入网设备通过DAM的ML模型和第四信息预测或估计邻居小区在第一时间内的调度信息。例如，该ML模型可以是亚力克斯网络(AlexNet)。第一接入网设备将邻居小区的第四信息输入上述ML模型，得到该ML模型输出的该邻居小区在第一时间内的调度信息，即第一信息。
如果要求第一信息的精确度较高，则第一接入网设备可以使用能够产生更高精确度的ML模型进行运算，以向终端设备提供精确度较高的第一信息。
504、第一接入网设备向终端设备发送第一信息。
505、终端设备根据第一信息确定目标CQI索引值。
506、终端设备向第一接入网设备发送目标CQI索引值。
步骤504至步骤506与前述图3A所示的实施例中的步骤302至步骤304类似，具体可以参阅前述图3A所示的实施例中的步骤302至步骤304的相关介绍，这里不再赘述。

例如，如图2所示，第一接入网设备为gNB204。第二接入网设备为gNB-CU205，gNB204通过Xn接口向gNB-CU205发送第四信息。
如果第一接入网设备与第二接入网设备之间没有存在直接通信的接口，第二接入网设备可以通过以下两种可能的方式向第一接入网设备发送第四信息。

2、上述图4所示的实施例的步骤502中，第二接入网设备可以网管控制设备发送第四信息，再由网管控制设备向第一接入网设备发送该第四信息。
上述示出第二接入网设备向第一接入网设备发送第四信息的两种可能的实现方式，并不属于对本申请的限定。对于其他发送方式同样适用于本申请。
需要说明的是，当第二接入网设备为CU、CU-CP或CU-UP时，上述图5所示的实施例中的步骤501具体包括：第二接入网设备从管理邻居小区的DU获取该第四信息。

在该实现方式下，步骤501具体包括：第二接入网设备从管理邻居小区的DU获取该第四信息。例如，管理邻居小区的DU向CU-CP发送邻居小区的第四信息。

在该实现方式下，步骤501具体包括：第二接入网设备从管理邻居小区的DU获取该第四信息。例如，管理邻居小区的DU向CU-CP发送邻居小区的第四信息。
上述图3A或图4或图5所示的实施例中，终端设备与第一接入网设备之间可以基于现有协议传输第一信息和第二信息。例如，第一信息承载于RRC消息，或者，通过物理层信息交互承载第一信息和第二信息。终端设备与第一接入网设备之间还可以采用新定义的专用协议(例如，如图6所示的数据分析协议(data analytics protocol，DAP)层)发送第一信息和第二信息，以实现第一信息和第二信息的分割、排序、完整性保护、加解密等功能。
图6示出了终端设备与第一接入网设备之间的新定义协议栈的一种示意图。在图6中，该新定义协议栈用于终端设备与第一接入网设备之间传输第一信息和第二信息。该定义的协议栈包括DAP层、分组数据汇聚层协议(packet data convergence protocol，PDCP)层、无线链路控制(radio link control，RLC层)、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层。
DAP层用于传输第一信息和第二信息，以实现第一信息和第二信息的分割、排序、完整性保护、加解密等功能。
PDCP层关联一种专用无线承载(例如，计算无线承载(computing radio bearer，CRB)，以实现第一信息和第二信息的有序发送、加解密、重复性检测等。
其中，PDCP层关联的CRB及CRB的功能介绍如下：
PDCP层可以建立用于传输计算数据的专用无线承载。例如，CRB。应理解，CRB仅是一种示例性命名，并不对该专用无线承载的命名进行具体限定。CRB传输的数据包大小、服务质量(quality of service，QoS)等级等可以适用计算数据。
下面示出CRB与信令无线承载(signaling radio bearer，SRB)(或数据无线承载(dat a radio bearer，DRB))的区别：
一、CRB可以与SRB(或DRB)采用不同的逻辑信道标识(logical channel identify，LCID)。
例如，CRB可以采用第三代合作伙伴计划(3rd generation partnership project，3GPP)标准中下行共享信道(downlink-shared channel，DL-SCH)或上行共享信道(uplink-shared channel，UL-SCH)中的保留(reserved)的LCID值。
二、CRB的QoS特性可以与SRB(或DRB)的QoS特性不同。
例如，CRB的QoS等级可以低于SRB的QoS特性(或者，DRB的QoS特性)。SRB没有包时延预算(packet delay budget，PDB)，CRB可以有PDB。
三、CRB传输的信息与SRB(或DRB)传输的信息不同。
例如，SRB承载的信息为信令，DRB承载的是来自于终端设备和数据网络的用户应用层数据。而CRB承载的无线网络内的计算数据。例如，CRB承载与ML任务相关联的数据等。
又例如，SRB承载的信息的数据量较小，而CRB承载的信息可以没有数据量的限制。
再例如，SRB传输信息时涉及终端设备的计费，而CRB传输信息时可以不涉及终端设备的计费。
此外，若CRB传输的数据为接入网设备的计算数据，CRB的数据传输可以是在接入网设备终止，即CRB传输的计算数据可以不回传到核心网设备。相比于通过DRB传输计算数据来说，通过CRB传输计算数据时传输路径较短，从而可以降低传输时延。并且，通过CRB传输计算数据时对终端设备的计费没有影响。
可选的，PDCP层可以包括用于实现计算数据的数据传输、计算数据的加解密、重复性检测等功能的子层。为了描述方便，可以将PDCP层支持计算数据的数据传输、计算数据的加解密、重复性检测等功能的子层称为“PDCP-CRB”子层。
上述图4所示的实施例中，第一接入网设备与第二接入网设备可以采用已有协议传输第三信息和第三信息请求。例如，第三信息和第三信息请求承载于Xn应用协议(Xn application protocol，XnAP)层。上述图5所示的实施例中，第一接入网设备与第二接入网设备可以采用已有协议传输第四信息和第四信息请求。例如，第四信息和第四信息请求承载于Xn应用协议层。
或者，上述图4所示的实施例中，第一接入网设备与第二接入网设备之间使用新的协议传输第三信息和第三信息请求。上述图5所示的实施例中，第一接入网设备与第二接入网设备之间使用新的协议发送第四信息和第四信息请求。
图7示出了第一接入网设备与第二接入网设备之间的新定义协议栈的一个示意图。图7中，新定义协议栈包括b类型高层数据分析协议(high data analytics protocol type b，HDAPb)层、Xn应用协议(Xn application protocol，XnAP)层、流控制传输协议(stream control transmission protocol，SCTP)层、互联网协议(internet protocol，IP)层、层2(layer2，L2)层和层1(layer1，L1)层。
b类型高层数据分析协议(high data analytics protocol type b，HDAPb)支持第一接入网设备与第二接入网设备之间的数据传输(例如，数据分割、数据排序)，以及数据安全(例如，数据完整性保护、数据加密、数据解密)等功能。HDAPb使用Xn应用协议(Xn application protocol，XnAP)提供的服务，即HDAPb消息承载在XnAP消息中。也就是上述图4所示的实施例中，第一接入网设备与第二接入网设备可以通过HDAPb消息传输第三信息和第三信息请求，且该HDAPb消息承载在XnAP消息中。上述图5所示的实施例中，第一接入网设备与第二接入网设备可以通过HDAPb消息传输第四信息和第四信息请求，且该HDAPb消息承载在XnAP消息中。
本申请实施例中，若第一接入网设备为DU，第二接入网设备为CU或CU-CP，或者，若第一接入网设备为CU或CU-CP，第二接入网设备为DU，上述图4所示的实施例中，第一接入网设备与第二接入网设备可以通过已有协议(例如，F1应用协议(F1application protocol，F1AP))传输第三信息和第三信息请求。若第一接入网设备为DU，第二接入网设备为CU或CU-CP，或者，若第一接入网设备为CU或CU-CP，第二接入网设备为DU，上述图5所示的实施例中第一接入网设备与第二接入网设备可以通过已有协议(例如，F1应用协议)传输第四信息和第四信息请求。
或者，若第一接入网设备为DU，第二接入网设备为CU或CU-CP，或者，若第一接入网设备为CU或CU-CP，第二接入网设备为DU，上述图4所示的实施例中，第一接入网设备与第二接入网设备之间可以使用新的协议传输第三信息和第三信息请求；而上述图5所示的实施例中，第一接入网设备与第二接入网设备之间可以使用新的协议传输第四信息和第四信息请求。
针对第一接入网设备为DU，第二接入网设备为CU或CU-CP，或者，第一接入网设备为CU或CU-CP，第二接入网设备为DU的情况，下面通过图8示出了第一接入网设备与第二接入网设备之间的新定义协议栈的一个示意图。在图8中，新定义协议栈包括c类型高层数据分析协议(high data analytics protocol type c，HDAPc)层、F1应用协议(F1application protocol，F1AP)层、SCTP层、IP层、L2层和L1层。
HDAPc协议支持第一接入网设备与第二接入网设备之间的数据传输(例如，数据分割、数据排序)，以及数据安全(例如，数据完整性保护、数据加密、数据解密)等功能。HDAPc消息可承载在F1AP消息中。也就是说上述图4所示的实施例中，第一接入网设备与第二接入网设备之间可以通过HDAPc消息传输第三信息和第三信息请求，且HDAPc消息承载在F1AP消息中。上述图5所示的实施例中，第一接入网设备与第二接入网设备之间可以通过HDAPc消息传输第四信息和第四信息请求，且HDAPc消息承载在F1AP消息中。
