Description

通信的方法、装置 技术领域
本申请涉及通信领域，并且，更具体地，涉及通信的方法、装置。
背景技术
在当前新接入技术(New Radio Access Technology,NR)系统中，无线信号在传播过程中，发射端发射的信号通过反射、折射、散射等多条路径传播，不同路径传播的信号到达接收端的时间不同，因此接收端接收的信号与发送端发送的信号相比产生了畸变，即多径效应。产生畸变的原因是信号在传播过程中通过的无线信道的信道系数在频域上会有起伏变化，即无线信道具有频率选择衰落特性。无线信道的频率选择衰落特性取决于环境，通常在阻挡物或潜在反射物较少的环境下，无线信道的频率选择衰落特性较小。而依托于长期演进(Long term evolution，LTE)和NR技术的固定无线接入(Fixed Wireless Access，FWA)网络，特别是室内固定无线接入场景，由于室内障碍物较多，多径效应严重，因此无线信道具有较强的频率选择性衰落。
无线通信系统采用频选调度的方式克服无线信道的频率选择衰落特性，即调度信道质量较优的资源块(Resource Block，RB)用于网络设备和终端设备之间的通信，从而获得信道的频率选择性信道增益。
现有技术中，网络设备调度的资源块对应的单个传输块只对应一个调制与编码策略(Modulation and Coding Scheme，MCS)，此时不能匹配无线信道的频率选择衰落特性，造成传输性能降低。

如图1所示，该无线通信系统100可以包括至少一个网络设备，例如图1所示的网络设备110。该无线通信系统100还可以包括至少一个终端设备，例如图1所示的终端设备120。终端设备与网络设备之间、终端设备与终端设备之间可以建立无线连接，进行无线通信，发送设备可以通过控制信息指示数据的调度信息，以便接收设备根据控制信息正确地接收数据。
本申请实施例中的终端设备也可以称为用户设备(User Equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。本申请的实施例中的终端设备可以是手机、平板电脑、室内或室外用户驻地设备(Customer Premises Equipment，CPE)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端设备、增强现实(Augmented Reality，AR) 终端设备、工业控制(Industrial Control)中的无线终端、无人驾驶中的无线终端、远程医疗中的无线终端、智能电网中的无线终端、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、蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端设备等。
应理解，本申请对于终端设备的具体形式不作限定。
本申请实施例中的网络设备可以是任意一种具有无线收发功能的设备。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(Base Band 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 point，TP)或者发送接收点(Transmission and Reception Point，TRP)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(Distributed Unit，DU)，还可以为未来移动通信系统中的基站或Wi-Fi系统中的接入节点等。

为便于理解本申请实施例，下面首先对本申请中涉及的几个术语做简单介绍。
1、子载波
子载波：正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)系统中将频域资源划分为若干个子资源，每个频域上的子资源可称为一个子载波。子载波也可以理解为频域资源的最小粒度。
2、子载波间隔
子载波间隔：OFDM系统中，频域上相邻的两个子载波的中心位置或峰值位置之间的间隔值。例如，LTE系统中的子载波间隔为15KHz，5G NR系统的子载波间隔可以是 15KHz，或30KHz，或60KHz，或120KHz等。
3、OFDM符号
OFDM符号：OFDM系统中时域上最小的时间单元，该OFDM系统为采用OFDM传输的通信系统，例如，LTE或者NR系统。
4、解调参考信号(Demodulation Reference Signal，DMRS)
DMRS：解调参考信号是用于对接收信号进行恢复的参考信号，DMRS为接收端已知的信号，接收端根据接收信号和已知的DMRS信号，可以确定无线信道的衰落特性，即无线信道的信道系数，用于对接收信号进行恢复。5G NR系统中，考虑到不同天线端口到终端的信道系数不尽相同，为了接收端能够获取多个空间层上传输的信息，需要对每个天线端口与终端之间的信道系数都进行估计，所以需要为每个天线端口配置不同的DMRS，不同天线端口对应的DMRS可采用时分、频分和/或码分等方式进行复用。目前，5G NR系统最大可支持12个MDRS端口。
5、资源块(Resource Block，RB)
资源块，频域上连续的N个子载波可称为一个资源块。例如，LTE系统中的一个资源块包括12个子载波，5G NR系统中的一个资源块也包括12子载波。随着通信系统的演进，一个资源块包括的子载波个数也可以是其他值。若干个资源块可以组成一个资源块组(Resource Block Group，RBG)，每个RBG包含的RB的数量可以通过DCI中的资源块捆绑“PRB Bundling”字段确定。
6、频域资源
频域资源为网络设备配置给终端设备的一部分频带(band)，用于进行数据传输，具体的，频域资源可以为分量载波(Component Carrier，CC)，也可以为带宽部分(Bandwidth Part，BWP)，还可以为载波频带等。本申请实施例对此不进行限定，其中，BWP可以为连续的频域资源，也可以为不连续的频域资源。
7、时隙(slot)
时隙为传输数据的资源在时域上的一种单位，一个时隙通常包含多个符号/码片，每个符号/码片可能有相同或不同的传输方向。5G NR系统的一个时隙包括14个OFDM符号，15kHz子载波间隔对应的时隙长度为1ms，30kHz子载波间隔对应的时隙长度为0.5ms。OFDM符号为OFDM系统中时域上最小的时间单元。
8、传输块(Transmit Block，TB)
上行数据信道(例如，物理上行共享信道)和下行数据信道(例如，物理下行共享信道)上以传输块为单位传输数据，TB的大小可以用传输块大小(Transmit Block Size，TBS)表示，单位为比特。目前，在5G NR系统中，终端设备最多可以同时接收或发送2个传输块。
9、调制与编码策略(Modulation and Coding Scheme，MCS)
MCS为网络设备向终端设备发送的下行信号中包含的传输块所采用的调制阶数和码率对应的调制与编码策略。网络设备通过在DCI中承载MCS的索引值，并通过高层信令指示终端设备所采用的MCS表格，终端设备根据在DCI中接收到的MCS索引值和高层信令指示的MCS表格确定采用的调制与编码策略，并根据所确定的调制预编码策略，确定采用的调制阶数和码率，以对下行信号进行处理。
5G NR系统中，网络设备向终端设备传输数据包时，网络设备通过在物理下行控制信道(Physical Downlink Control Channel，PDCCH)中向终端用户发送下行控制信息(Downlink Control Information，DCI)，指示终端设备接收下行数据。
该DCI通过“频域资源分配(Frequency domain resource assignment)指示”字段指示终端设备用于接收下行信号的资源块。
通过“调制编码方案(Modulation and Code Scheme，MCS)指示”字段指示的MCS索引值和高层信令指示的MCS索引表指示终端设备从上述资源块上接收的信号包含的所对应的MCS。
在上述DCI中，每一个传输块只对应一个MCS，也就是说网络设备调度的资源块对应的单个传输块只对应一个MCS。此时不能匹配无线信道的频率选择衰落特性。若要克服这个问题，则需要网络设备配置多个MCS对应所调度的资源块上承载的单个传输块，并指示终端设备其中每个MCS所对应的承载部分传输块的频域资源。
本申请实施例中，为解决上述问题，网络设备通过发送一个或多个信令，为单个传输块配置多个MCS，从而减缓无线信道的频率选择衰落特性。
图2为适用本申请实施例提供的通信方法200的示意性流程图，该方法包括：
S210网络设备发送第一信令给终端设备，对应地，终端设备接收第一信令，该第一信令包括用于指示第一频域资源和第一MCS的第一指示信息，该第一频域资源包括第二频域资源。
应理解，网络设备发送第一信令前，可以根据终端设备发送的信道探测参考信号和/或解调参考信号等上行参考信号估计信道的状态，并根据信道状态确定调度的频域资源以及该频域资源上承载的信号对应的第一MCS，然后通过第一信令指示终端设备。该第一频域资源可以为承载网络设备向终端设备待发送下行信号的资源块。
一种实施方式中，该第一指示信息包括2个字段，第一字段用于指示第一频域资源，第二字段用于指示第一MCS的索引值，也即此时，用于指示第一频域资源的字段和第一MCS的索引值的字段为两个不同的字段。该第一指示信息中的第一字段和/或第二字段可以为现有协议中的指示字段，可以为现有协议中的预留字段，也可以为现有协议中未定义的新增字段。举例说明，若第一信令为DCI，则第一字段可以为协议3GPP(3rd Generation Partnership Project)TS 38.212中定义的DCI格式中的频域资源分配“Frequency domain resource assignment”的字段。第二字段可以为协议3GPP TS 38.212中定义的DCI格式中的调制与编码策略“Modulation and coding scheme”的字段，或者若第一信令为RRC信令，可以在RRC信令中增加用于指示第一频域资源的字段和用于指示第一MCS的字段。
可选的，该第一信令还可以包括用于指示第二时间段的第四指示信息。该第四指示信息可以指示第二时间段的时隙偏移量与起始和长度指示值(Start and length Indicator Value，SLIV)。该SLIV用于确定第二时间段内的首个OFDM符号和最后一个OFDM符号。该第四指示信息可以为现有协议中的指示字段，可以为现有协议中的预留字段，也可以为现有协议中未定义的新增字段。举例说明，若第一信令为DCI，则该第四指示信息可以为现有DCI中用于指示时域资源分配“Time Domain Resource Assignment”的字段，若第一信令为RRC信令，可以在RRC信令中增加用于指示第二时间段的字段。。
一种实施方式中，该第一信令可以承载于物理下行共享信道(Physical Downlink Shared  Channel，PDSCH)中。举例说明，该第一信令为RRC信令，当然，该第一信令也可以是除RRC外的其它高层信令，在此不做限定。
另一种实施方式中，第一信令也可以承载于物理下行控制信道PDCCH中。举例说明，该第一信令为DCI，当然，该第一信令也可以是除DCI外的其他信令，在此不做限定。
S220网络设备发送第二信令，对应地，终端设备接收第二信令，该第二信令包括用于指示第二频域资源和第二MCS的第二指示信息，该第一频域资源包括第二频域资源。
具体地，该第二指示信息包括用于指示该第二频域资源和第二MCS的2个字段，第一字段用于指示第二频域资源，第二字段用于指示第二MCS的索引值。该第二指示信息中的第一字段和/或第二字段可以为现有协议中的指示字段，可以为现有协议中的预留字段，也可以为现有协议中未定义的新增字段。举例说明，若第二信令为DCI，则第一字段可以为协议3GPP(3rd Generation Partnership Project)TS 38.212中定义的DCI格式中的频域资源分配“Frequency domain resource assignment”的字段。第二字段可以为协议3GPP TS 38.212中定义的DCI格式中的调制与编码策略“Modulation and coding scheme”的字段。。
一种实施方式中，该第一字段可通过比特位图的方式指示第二频域资源。该比特位图的比特长度可以为第一频域资源所包括的RB的数量。或该位图的比特长度可以为第一频域资源所包括的RBG的数量，其中，每一个比特对应一个RB或者一个RBG，每一个比特的不同值表征其对应的RB或者RBG的不同状态。例如，比特位的值设置为1，指示此比特位对应的资源块包含于第二频域资源中，比特位的值设置为0，指示此比特位对应的资源块不包含于第二频域资源中，同样地，也可以是若该比特位的值设置为0，指示此比特位对应的资源块包含于第二频域资源中，若该比特位的值设置为1，指示此比特位对应的资源块不包含于第二频域资源中，在此不做限定。
示例的，如表1所示，若第一频域资源中包含8个RB，编号为RB0-RB7，若位图为[11110000]，则指示RB0、RB1、RB2、RB3包含于第二频域资源中；位图为[11101000]，则指示RB0、RB1、RB2、RB4包含于第二频域资源中；位图为[11100100]，则指示RB0、RB1、RB2、RB5包含于第二频域资源中；位图为[11111000]，则指示RB0、RB1、RB2、RB3、RB4包含于第二频域资源中；位图为[11110100]，则指示RB0、RB1、RB2、RB3、RB5包含于第二频域资源中。
表1
位图 第二频域资源中包含的RB编号
[11110000] 0,1,2,3
[11101000] 0,1,2,4
[11100100] 0,1,2,5
… …
[11111000] 0,1,2,3,4
[11110100] 0,1,2,3,5
… …
另一种实施方式中，该第一字段还可通过资源指示值指示第二频域资源，该资源指示值指示第一频域资源中第二频域资源的起始RB的位置和连续RB的数目，例如，该资源指示信息指示第一频域资源中从第S个RB开始连续的L个RB属于第二频域资源。该资 源指示值的计算方式可采用协议3GPP TS 38.214标准中Type 1频域资源分配的资源指示值的计算方式。
具体地，一种实施方式中，第二字段指示该第二MCS的索引值，并通过高层信令指示终端设备所采用的MCS索引表，终端设备可根据该第二MCS的索引值在网络设备指示的MCS索引表中确定该第二MCS。
另一种实施方式中，第二字段可以指示一个偏差值。该偏差值为第一MCS的索引值与第二MCS的索引值的差值。终端设备可根据该偏差值和该第一MCS确定该第二MCS。
可选地，第二信令还可以包括用于指示第一时间段的第三指示信息。第一时间段包含于第二时间段。即所述第一时间段包含的时隙数量为第二时间段包含的时隙中的一个、多个或者全部，或第一时间段包含的OFDM符号为第二时间段包含的OFDM符号中的一个、多个或者全部。
可选的，第二信令还包括用于指示第一MCS偏差值的指示信息。或第二信令还包括用于指示第三MCS的指示信息。该第一MCS偏差值用于确定第三MCS的索引值。该第一MCS偏差值为第三MCS的索引值与第一MCS的索引值的差值。该第三MCS为第三频域资源对应的MCS，即第一频域资源中除第二频域资源外的频域资源对应的MCS。该第三频域资源为第二频域资源在第一频域资源中的补集。
应理解，当网络设备发送的第二信令指示的第一MCS偏差值为零，或者该第二信令没有指示第三MCS或第一MCS偏差值，此时终端设备可以确定第三频域资源上承载的信号采用的MCS为第一信令所指示的第一MCS。具体网络设备是否需要通过第二信令指示第三MCS或第一MCS偏差量，在此不做限定。
一种实施方式中，第二信令中用于指示第一MCS偏差值的字段可以位于第二信令中用于指示第二频域资源的字段之后。或第二信令中用于指示第三MCS的字段可以位于第二信令中用于指示第二频域资源的字段之后。
应理解，若第二信令通过比特位图的方式指示第二频域资源，则该比特位图包含的比特数目和第一频域资源块中包含的RB或者RBG的数目相同，因为第一频域资源中的RB数量小于网络设备为终端设备配置的带宽中所包含的RB的数量，或第一频域资源中的RBG数量小于网络设备为终端设备配置的带宽中所包含的RBG的数量，所以降低了第二信令指示第二频域资源的信令开销，网络设备可以通过这种方式下节省的比特中的一个或多个比特指示第三MCS或第一MCS偏差值。
一种实施方式中，第二信令可以承载于PDCCH中，举例说明，第二信令可以为DCI，但不限于此。
S230终端设备根据该第一信令和第二信令确定在第一时间段内的该第一频域资源上接收第一下行信号，其中，该第一下行信号中承载于该第二频域资源上的部分对应的MCS为第二MCS，该第一下行信号中承载于第三频域资源上的部分对应的MCS为第一MCS或第三MCS，该第三频域资源为该第一频域资源中不包括该第二频域资源的频域资源，该第三MCS基于该第一MCS确定。
该第一下行信号为第一时间段内承载于第一频域资源上的网络设备向终端设备发送的下行信号。
具体地，终端设备根据该第一信令和第二信令确定在第一时间段内的该第一频域资源 上接收第一下行信号。其中，终端设备可以根据该第一信令和第二信令确定，包括：
终端设备可以根据第一信令确定第一频域资源和第一MCS。即终端设备可以根据第一信令确定第一频域资源和第一MCS的索引值。
可选地，终端设备可以根据第一信令确定第二时间段。具体来说终端设备可以根据第一信令中的时隙偏移量与SLIV，确定第二时间段内的首个OFDM符号和最后一个OFDM符号。该第二时间段包括该第一时间段。
可选的，终端设备可以根据第二信令确定第一时间段。终端设备可以根据第二信令中的时隙偏移量与SLIV，确定第一时间段内的首个OFDM符号和最后一个OFDM符号。
终端设备可以根据第二信令确定第二MCS，具体地，终端设备可以根据第二信令确定第二MCS的索引值，并根据高层信令指示的MCS索引表确定第二MCS。第二MCS指示的调制与编码策略为第一时间段内承载于第二频域资源上的第一下行信号采用的调制与编码策略。
终端设备可以根据该第一信令和第二信令确定该第二频域资源和第三频域资源。该第二频域资源包含于第一频域资源。该第三频域资源为该第一频域资源中不包括该第二频域资源的频域资源。也就是说，终端设备可以根据第二信令确定第二频域资源，因为第三频域资源为该第一频域资源中该第二频域资源的补集，所以终端设备同样可以确定第三频域资源。如图3所示，第一频域资源中包含20个RB，编号为RB0到RB19，第二频域资源中包含RB0～RB3和RB14～RB19，则第三频域资源中包含RB4～RB13。
应理解，第二频域资源和第三频域资源的资源块数量可以是网络设备根据终端设备上报的参数或根据终端设备发送的上行参考信号等确定的，图3中第二频域资源和第三频域资源的资源块数量仅为示例，在此不做任何限定。
可选地，终端设备可以根据第一MCS确定第三MCS。也可以说，终端设备可以根据第一信令和/或第二信令确定第三MCS。具体地，终端设备可以根据第二信令确定第一MCS偏差值，终端设备可以根据该第一MCS的索引值和该第一MCS偏差值确定第三MCS的索引值，并通过高层信令指示的MCS索引表确定该第三MCS。
一种实施方式中，终端设备可通过接收的第二信令中用于指示第一MCS偏差值的指示信息确定第一MCS偏差值，从而确定第三MCS。举例说明，当第一MCS所对应的MCS索引值为I，当第一偏差值MCS为0时，第三MCS索引值为I；当第一MCS偏差值为1时，第三MCS索引值为I+1；当第一MCS偏差值为-1时，第三MCS索引值为I-1；当第一偏差值为2时，第三MCS索引值为I+2；当第一MCS偏差值为-2时，第三MCS索引值为I-2。
终端设备可以根据第一信令和第二信令确定第一时间段内第三频域资源对应的MCS为第一MCS或第三MCS。
终端设备可以根据第二信令确定第一时间段内第二频域资源对应的MCS为第二MCS。
可选的，网络设备调度终端设备接收下行信号的方式可以包括以下两种：
第一种可能的方式：
第一信令调度终端设备接收下行信号。终端设备接收的第一信令和第二信令都可以承载于PDCCH中。
一种实施方式中，第一信令包括第四指示信息，指示终端设备在第二时间段内接收下行信号即第一信令可以调度终端设备接收网络设备发送的下行信号，该下行信号为第二下行信号。该第二下行信号为第二时间段内承载于第一频域资源的下行信号。该第二下行信号承载于所述第一时间段内的部分为该第一下行信号，其中，该第二时间段包括该第一时间段。终端根据第一信令和第二信令接收下行信号，具体步骤包括：
S2311终端设备根据第一信令确定第一频域资源和第一MCS，终端设备也可以根据第一信令确定第二时间段。
S2312终端设备根据第一信令，在第二时间段内接收承载于第一频域资源上的第二下行信号。
S2313终端设备根据该第一信令和第二信令确定在第一时间段内的该第一频域资源上接收第一下行信号。
具体地，终端设备接收到该第一信令和第二信令后的第一时间段内，在该第二频域资源和第三频域资源上接收第一下行信号，并通过该第二MCS指示的调制与编码策略处理该第一下行信号中承载于该第二频域资源上的部分，通过该第三MCS指示的调制与编码策略或第一MCS指示的调制与编码策略处理该第一下行信号中承载于第三频域资源上的部分。应理解，当第二信令指示的第一MCS偏差值为0或第二信令不包括第一MCS偏差值的指示信息或第二信令不包括指示第三MCS的指示信息时，依然通过第一MCS指示的调制与编码策略处理该第一下行信号中承载于第三频域资源上的部分；当第二信令指示的第一MCS偏差值不为0或第二信令包括用于指示第三MCS的指示信息时，终端设备通过第三MCS指示的调制与编码策略处理该第一下行信号承载于第三频域资源的部分。
应理解，上述终端设备在第二频域资源上接收部分信号和在第三频域资源上接收部分信号的顺序可以是在第三频域资源上接收部分信号在前，也可以是在第二频域资源上接收部分信号在前，还可以是同时进行接收，在此不做限定。
示例地，如图4所示，终端设备在时隙i接收到第一信令和第二信令，第一信令指示第二时间段包括20个时隙，即时隙i到时隙i+19，第二信令指示第一时间段包含5个时隙，即时隙i到时隙i+4，终端设备在时隙i到时隙i+4，在第二频域资源上接收第一下行信号中的部分信号，并根据第二MCS对其部分信号进行解调，在第三频域资源上接收第一下行信号中的部分信号，并根据第一MCS或第三MCS对其部分信号进行解调；在时隙i+5到时隙i+19，终端设备在第一频域资源上接收信号，并根据第一MCS对该信号进行解调。
应理解，如果终端设备接收到第一信令和第二信令后的某个时隙，此时第一时间段已经结束，第二时间段还没有结束时，终端设备再次接收到第二信令，则重复上述终端设备接收到第二信令后的步骤。如果终端设备接收到第一信令和第二信令后的某个时隙，此时第一时间段已经结束，第二时间段还没有结束时，终端设备没有再接收到第二信令，则终端设备在第二时间段除第一时间段的时间段内从第一频域资源上接收第二下行信号，并根据第一MCS对第二下行信号进行解调。
还应理解，如果终端设备只接收到该第一信令，没有接收到该第二信令，则终端设备根据该第一信令确定第一频域资源和第一MCS，然后在第二时间段内从第一频域资源上接收第二下行信号，并根据该第一MCS对该第二下行信号进行处理。
该第一信令和第二信令可以为同一信息，也可以为不同的信息，以DCI举例说明，第一信令和第二信令可以为同一DCI，也可以为不同的DCI，在这里不做限定。
第二种可能的方式：
第二信令调度终端设备接收下行信号。终端设备接收的第一信令可以承载于PDSCH，第二信令可以承载于PDCCH中。
具体地，第二信令调度终端设备接收网络设备发送的下行信号，该下行信号为第一下行信号。该第一下行信号为第一时间段内承载于第一频域资源的下行信号。即第二信令指示终端设备接收第一下行信号。
可选地，第一信令还包括用于指示第二时间段的第四指示信息，该第二时间段包括第一时间段。应理解，第一信令可以不包括指示第二时间段的第四指示信息，即当第一信令包括第四指示信息时，终端设备可以在第二时间段内根据第一信令，确定第一频域资源和第一MCS；当第一信令不包括第四指示信息时，在接收到下一个第一信令前，终端设备都可以根据第一信令，确定第一频域资源和第一MCS。
终端设备根据该第一信令和第二信令接收下行信号，具体步骤如下：
S2321终端设备根据第一信令确定该第一频域资源和第一MCS。
可选的，终端设备还可以根据第一信令确定第二时间段。应理解，当网络设备发送的第一信令不包括用于指示第二时间段的第四指示信息时，终端设备可以不执行此操作。
S2322终端设备根据该第一信令和第二信令确定在第一时间段内的该第一频域资源上接收第一下行信号，具体地，接收第一下行信号的步骤同S2313，在此不做赘述。
应理解，如果终端设备接收的第一信令除了用于指示第一频域资源和第一MCS外，还用于指示第二时间段，终端设备在根据该第一信令息和第二信令确定在第一时间段内的该第一频域资源上接收第一下行信号后，在第二时间段内除了第一时间段的时间内不接收下行信号。也就是说终端设备在只接收到第一信令时，并不进行第一下行信号的接收，只需确定该第一频域资源和第一MCS。
终端设备接收到该第二信令后，才进行S2322步骤的操作。
可选地，该第一信令可以为RRC，该第二信令可以为DCI上，在此仅做举例，不做限定。
应理解，若第一信令为RRC时，由于现有的RRC信令没有指示频域资源和MCS索引值的字段，因此指示频域资源和MCS索引值的字段可通过在RRC中新增加字段实现。
具体地，网络设备根据RRC中的MCS指示字段指示该第一MCS的索引值，并通过高层信令指示终端设备所采用的MCS索引表，终端设备可根据该第一MCS的索引值在网络设备指示的MCS索引表中确定该第一MCS，通过RRC信令中新增的用于指示第二时间段的字段确定该第二时间段。
