Description

通信方法、通信装置及存储介质
本申请要求于2019年1月10日提交中国专利局、申请号为201910023940.5、发明名称为“通信方法、通信装置及存储介质”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
本申请涉及无线通信领域，特别是一种通信方法、通信装置及存储介质。
背景技术
下一代(new generation，NG)移动通信系统支持超可靠低延迟通信(Ultra-reliable and low latency communications,URLLC)业务。URLLC业务对可靠性需求高，因此信道状态信息(channel stat information，CSI)反馈技术十分重要，通过触发非周期性信道状态信息(aperiodic channel state information，A-CSI)反馈，可以迅速及时地获取信道和干扰信息，辅助改善后续数据传输质量。
为了避免A-CSI反馈带来额外的下行控制信息(downlink control information，DCI)开销，现有技术中提出了A-CSI在上行控制信道，例如短格式物理上行控制信道(short physical uplink control channel，short PUCCH)上反馈的方案，通过调度下行URLLC数据的DCI同时触发终端设备在上行控制信道上反馈A-CSI，降低DCI开销。
对于在上行控制信道上反馈的A-CSI，一旦与同样使用上行控制信道发送的确认消息(acknowledge)/否认消息(negative acknowledge，NACK)重叠，需要对A-CSI与ACK/NACK进行联合反馈。但是，如果终端设备漏检触发A-CSI的DCI，则网络设备对于联合反馈的上行控制信息(uplink control information，UCI)理解会与终端设备不一致，导致接收错误。
发明内容
本申请实施例提供了一种通信方法、通信装置及存储介质，可以提升上行信息的接收正确性。
第一方面，本申请实施例提供了一种通信方法，包括：确定上行信息；当所述上行信息为第一反馈信息，确定所述第一反馈信息对应的第一上行控制信道资源并在所述第一上行控制信道资源上发送所述第一反馈信息；当所述上行信息包括A-CSI，确定所述上行信息对应的第二上行控制信道资源并在所述第二上行控制信道资源上发送所述上行信息；其中，所述第一上行控制信道资源与所述第二上行控制信道资源不同。
该方法可以由终端设备或者可用于终端设备的通信装置，例如芯片执 行。
其中，所述第一反馈信息可以是指示下行数据传输解码正确或不正确的反馈信息，例如ACK/NACK。可选地，所述第一反馈信息与所述A-CSI可以分别由不同的DCI指示在重叠的时域资源上发送。
在第一方面的一种可能的实现方式中，所述方法还包括：接收第一指示信息，所述第一指示信息用于指示第一组上行控制信道资源集，所述第一组上行控制信道资源集包括至少一个上行控制信道资源集；接收第二指示信息，所述第二指示信息用于指示第二组上行控制信道资源集，所述第二组上行控制信道资源集包括至少一个上行控制信道资源集；其中，所述第一组上行控制信道资源集与所述第二组上行控制信道资源集中至少有一个上行控制信道资源集不同。可选地，第一指示信息和第二指示信息是高层配置的。

在本申请中，终端设备120可以是向用户提供语音和/或数据连通性的各类设备，例如可以是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120可以经接入网，例如无线接入网(radio access network，RAN)与核心网进行通信，与RAN交换语音和/或数据。该终端设备120可以包括用户设备(user equipment，终端设备)、无线终端设备、移动终端设备、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、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)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、计算机内置的或者车载的移动装置，智能穿戴式设备等。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)、智能手环、智能手表等设备。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 freq终端设备ncy 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。此外，终端设备120还可以是无人机设备。在本申请实施例中，应用于上述设备中的芯片也可以称为终端设备。
在本申请中，网络设备110可以是接入网设备，所述接入网设备可以用于将终端设备110接入RAN等接入网。网络设备110可以是第三代合作伙伴计划(3rd generation partnership project，3GPP)所定义的基站，例如，可以是LTE系统中的基站设备，即演进型节点B(evolved NodeB，eNB/eNodeB)；还可以是NR系统中的接入网侧设备，包括gNB、传输点(trasmission point，TRP)，家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或者由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的接入网设备，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构将基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。此外，当eNB连接5G核心网(5G-Core，5G CN)时，LTE eNB也可以称为eLTE eNB。具体地，eLTE eNB是在LTE eNB基础上演进的LTE基站设备，可以直接连接5G CN，eLTE eNB也属于NR中的基站设备。网络设备110还可以是无线端点(wireless terminal，WT)，例如接入点(access point，AP)或者接入控制器(access controller，AC)，或者其他具有与终端、及核心网通信能力的网络设备，例如，中继设备、车载设备、智能穿戴设备等，本申请实施例对网络设备的类型不做限定。
通信系统100仅是举例说明，适用本申请的通信系统不限于此，例如，通信系统100中包含的网络设备和终端设备的数量仅为举例，通信系统100中可以包含多于一个的终端设备及网络设备。一个网络设备可以管理一个或多个终端设备，即一个或多个终端设备可以通过同一个网络设备接入网络。此外，通信系统100中还可以包括其它设备，例如，还可以包括无线中继设备和无线回传设备等，图1中不做示意。
本申请实施例定义接入网到终端的单向通信链路为下行链路，在下行链路上传输的数据为下行数据，下行数据的传输方向称为下行方向；而终端到接入网的单向通信链路为上行链路，在上行链路上传输的数据为上行数据，上行数据的传输方向称为上行方向。
本申请实施例中所述的资源也可以称为传输资源，包括时域资源、频域资源、码道资源中的一种或多种，可以用于在上行通信过程或者下行通信过程中承载数据或信令。
本申请实施例中所述的时间单元是指网络设备和终端设备之间用于无线通信的时域资源的单位。一段时域资源可以划分为多个时间单元。并且，在本申请中，多个时间单元可以是连续的，也可以是非连续的，即，某些相邻的时间单元之间存在预设的时间间隔。本申请对一个时间单元的长度不做 限定。例如，一个时间单元可以是一个或多个子帧(subframe)；或者，也可以是一个或多个时隙(slot)；或者，也可以是一个或多个符号(symbol)。其中，符号也称为时域符号，时域符号可以是正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，也可以是单载波频分多址(single carrier frequency division multiple access，SC-FDMA)符号。
本申请实施例中所述的码本包括在上行时间单元上反馈的、与下行数据对应的ACK/NACK的集合。其中，ACK/NACK对应的下行数据传输是由DCI直接调度或者是由一个DCI激活后按预设样式发送，因此ACK/NACK可以认为是由DCI触发的，所述DCI还可以指示/触发终端设备反馈A-CSI，终端设备可以在同一上行时间单元上同时向网络设备发送所述码本与所述A-CSI，也可以在不同上行时间单元上分别向网络设备发送所述码本与所述A-CSI。本申请实施例中的码本包括动态码本和半静态码本。可以理解，所述码本中还可以包含其他上行信息，不做限定。
其中，动态码本又称为类型2(Type 2)码本。终端设备可以在每个PDCCH监测时机(monitoring occasion)检测PDCCH，获取下行控制信息(downlink control information，DCI)，根据DCI中的时域资源分配(time domain resource allocation)字段和PDSCH-to-HARQ-timing字段确定该PDCCH调度的PDSCH对应的ACK/NACK的反馈时隙。终端设备首先根据PDCCH的时隙编号与时域资源分配字段中包含的PDCCH到PDSCH的时隙偏移值(K0)确定PDSCH的时隙编号，然后根据PDSCH-to-HARQ-timing字段获取定时偏移量(K1)，即PDSCH的时隙到该PDSCH对应的反馈时隙的偏移值，从而确定在哪个时隙内发送ACK/NACK。对于一个上行时隙，终端设备可以只反馈实际调度的、指向该时隙的ACK/NACK，由于基站在调度数据并触发ACK/NACK时，会对ACK/NACK指向同一个上行时隙的下行数据进行计数，其中，计数器对应的值可以通过下行分配索引(downlink assignment index,DAI)表示，所述DAI包含在DCI中，因此，UE可以根据收到的PDCCH中的DAI，确定自己是否有漏检某个DCI，使得反馈ACK/NACK的码本大小不出错。
半静态码本又称类型1(Type 1)码本。网络设备通过协议预定义或高层信令为终端设备配置K1集合(K1 set)和时域资源分配表格，终端设备根据时域资源分配表格确定PDSCH的候选时域位置，并根据PDSCH的候选时域位置和K1集合确定该PDSCH的反馈信息可能所在的时隙。在每个上行时隙，终端设备根据PDSCH的候选时域位置和K1集合确定该上行时隙关联的下行PDSCH时机集合，即关联的下行时隙和下行时隙内的PDSCH时机集合，再根据关联的下行PDSCH时机集合生成码本。也就是说，对于一个上行时隙，反馈的半静态码本的大小是固定的，可以包含所有可能指向该时隙的下行数据传输的ACK/NACK。
可以理解，上述动态码本和半静态码本的说明中以时间单元为时隙为例，不构成对本申请的任何限定。
本申请实施例中所述的上行控制信道资源集包括一个或多个上行控制 信道资源。以上行控制信道是PUCCH为例，目前NR系统中配置了K(1≤K≤4)个PUCCH资源集(PUCCH resource set)，第k个PUCCH资源集(k＝0，或，1，或2，或，3)用于承载的ACK/NACK的负载大小(payload size)的N UCI的取值范围为N k≤N UCI<N k+1，其中，N UCI表示UCI的比特数目，N为正整数。目前NR系统中规定N 0＝1&N 1＝3&N 4＝1706。换言之，ACK/NACK的负载大小也可以用UCI的比特数目表征。本申请实施例中所述的一组上行控制信道资源集也可以称为一个上行控制信道资源组(resource set group)。一个上行控制信道资源组可以包括一个或多个上行控制信道资源集，该一个或多上行控制信道资源集可以是现有协议中定义的，也可以是本申请中新定义的，不做限定。
应理解，本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，表示前后关联对象是一种“或”的关系。
应理解，在本发明实施例中，“与A对应的B”表示B与A相关联。在一种实现方式中，可以根据A确定B。但还应理解，根据A确定B并不意味着仅仅根据A确定B，还可以根据A和/或其它信息确定B。本申请实施例中出现的“多个”是指两个或两个以上。
本申请实施例中出现的第一、第二、第三等描述，仅作示意与区分描述对象之用，没有次序之分，也不表示本申请实施例中对信息数量的特别限定，不能构成对本申请实施例的任何限制。
本申请实施例中出现的“连接”是指直接连接或者间接连接等各种连接方式，以实现设备间的通信，本申请实施例对此不做任何限定。
本申请实施例中出现的“传输”(transmit/transmission)如无特别说明，是指双向传输，包含发送和/或接收的动作。具体地，本申请实施例中的“传输”包含数据的发送，数据的接收，或者数据的发送和数据的接收。或者说，这里的数据传输包括上行和/或下行数据传输。数据可以包括信道和/或信号，上行数据传输即上行信道和/或上行信号传输，下行数据传输即下行信道和/或下行信号传输。
本申请实施例中出现的业务(service)是指终端从网络侧获取的通信服务，包括控制面业务和/或数据面业务，例如语音业务、数据流量业务等。业务的发送或接收包括业务相关的数据(data)或信令(signaling)的发送或接收。
本申请实施例中出现的“网络”与“系统”表达的是同一概念，通信系统即为通信网络。
本申请中对于使用单数表示的元素旨在用于表示“一个或多个”，而并非仅表示“一个且仅一个”，除非有特别说明。“一些”可以是指一个或多个。
下面以通信系统100为NR系统为例进行说明。
在终端设备120与网络设备110的通信过程中，终端设备120可以进行CSI测量并将测量结果反馈给网络设备110，使得网络设备110能通过调整发射信号强度等方式提升通信链路性能，从而提升业务传输的可靠性。
A-CSI反馈是CSI反馈的一种类型。当有业务到达时，可以通过DCI触发或者隐式触发等方式触发A-CSI反馈，辅助改善后续数据传输质量。A-CSI反馈可以承载在上行数据信道，如PUSCH，也可以承载在上行控制信道，如物理上行控制信道(physical uplink control channel，PUCCH)。一种可能的实现方法是，通过调度下行数据的DCI同时触发终端设备在短格式上行控制信道(short PUCCH，sPUCCH)上反馈A-CSI，这样可以降低DCI开销，并实现A-CSI快速反馈。
对于在sPUCCH上进行的A-CSI反馈，若承载A-CSI的PUCCH资源与承载ACK/NACK(以下简称“A/N”)的PUCCH资源在时域上重叠，则A-CSI与A/N可以进行联合反馈。具体地，终端设备120可以将A-CSI与A/N进行联合编码，并根据接收到的最后一个DCI中的ARI来选择PUCCH资源承载上述A-CSI与A/N。
本申请中所述的A-CSI与A/N的联合反馈可以是指A-CSI与触发该A-CSI的DCI调度的下行数据对应的A/N的联合反馈(或称为联合发送)；也可以是指A-CSI与其他DCI调度的下行数据对应的A/N的联合反馈，不做限定。
图2(a)为联合反馈模式下，A-CSI与A/N进行联合反馈的一个示例。在联合反馈模式下，由于触发A-CSI的DCI本身也调度下行数据，若终端设备120针对该下行数据反馈A/N，则A-CSI可以与A/N在相同的时隙、相同的PUCCH资源上联合反馈。如图2(a)所示，DCI 1在上行时隙0(slot 0)调度了下行数据，并通过DCI中CSI Request字段取值为01指示触发了一个A-CSI在sPUCCH上反馈，同时，通过DCI 1中PDSCH-to-HARQ-ACK-Timing字段K1取值为2，指示下行数据对应的第一A/N与A-CSI在上行时隙2(slot 2)中联合反馈，而在上行时隙1(slot 1)中，DCI 2调度了下行数据，但没有触发A-CSI，通过DCI 2中PDSCH-to-HARQ-ACK-Timing字段K1取值为1指示DCI 2调度的下行数据对应的第二A/N在slot 2中反馈。因此，在图2(a)的场景中，A-CSI与第一A/N、第二A/N联合反馈。
图2(b)为单独反馈模式下，A-CSI与A/N进行联合反馈的一个示例。在单独反馈模式下，虽然触发A-CSI的DCI本身也调度下行数据，但是终端设备120在不同时隙或者同一时隙的不同PUCCH资源上分别反馈该DCI触发的A-CSI与该下行数据对应的A/N，且由网络设备110向终端设备120指示A-CSI反馈的时隙和/或PUCCH资源。如图2(b)所示，DCI 1在slot 0调度了下行数据并通过DCI1中CSI Request字段取值为01指示触发了一个A-CSI在sPUCCH上反馈，同时，通过DCI 1中PDSCH-to-HARQ-ACK-Timing字段K1取值为1，指示下行数据对应的第一A/N在上行slot 1中反馈，通过A-CSI的Timing字段Y取值为2指示A-CSI 在上行slot 2中反馈。而在slot 1中，DCI 2调度了下行数据，没有触发A-CSI，通过DCI 2中PDSCH-to-HARQ-ACK-Timing字段K1取值为1指示DCI 2调度的下行数据对应的第二A/N在slot 2中反馈。因此，在图2(b)的场景中，A-CSI与第一A/N单独反馈、且A-CSI与第二A/N联合反馈。
可以理解，上述联合反馈模式与单独反馈模式是以A-CSI是否与触发该A-CSI的DCI指示的A/N是否联合反馈来区分的，在单独反馈模式下，A-CSI可以与其他DCI指示的A/N重叠，从而进行联合反馈。
本申请实施例中所述的“在时域上重叠”或者“重叠”可以是指在时域上占用的时间单元有重叠，包括全部重叠或者部分重叠，所述时间单元可以是符号或者时隙。例如，在2(a)场景下，A-CSI与第一A/N、第二A/N可以在同一时隙上反馈，占用的时隙有重叠，即使三者占用了同一时隙上的不同符号，仍然属于本申请实施例所述的“在时域上重叠”的范畴；在2(b)场景下，A-CSI与第二A/N占用的符号有重叠，属于本申请实施例所述的“在时域上重叠”的范畴。
对于以上任意一种场景，如果终端设备120漏检DCI 1，则会认为在slot 2中只需要反馈A/N，不需要反馈A-CSI，那么终端设备120只反馈A/N，但是网络设备110仍然按照终端设备120同时反馈A/N与A-CSI的规则接收A/N，会造成A/N也接收失败。
为了解决该问题，本申请实施例提供了一种通信方法，通过为ACK/NACK等反馈信息和包含A-CSI的上行信息分配不同的上行控制信道资源，使得网络设备能够正确接收终端设备发送的上行信息，且无需多次盲检，降低接收复杂度。
为了便于说明，以终端设备以及网络设备作为执行主体为例，对本申请实施例所示的通信方法予以说明，可以理解，本申请实施例所述的通信方法的执行主体也可以是其他通信装置，例如芯片，下文将不再做说明。
图3是本申请实施例提供的一种通信方法的流程示意图。该方法包括：
S301：终端设备确定上行信息。
具体地，所述上行信息包括反馈信息和/或A-CSI。其中，所述反馈信息可以包括用于指示发送所述A-CSI的DCI调度的下行数据对应的反馈信息和/或其他DCI调度的下行数据对应的反馈信息。所述反馈信息具体可以是ACK/NACK，所述ACK可以表示下行数据传输解码正确，所述NACK可以表示下行数据传输解码不正确。
可以理解，本申请实施例不限定终端设备确定和发送除上述反馈信息和/或A-CSI之外的其他上行信息，例如，终端设备还可以确定和发送调度请求(scheduling request，SR)等其他类型的上行信息。
为了便于说明，在本申请实施例中，上述用于指示发送所述A-CSI的DCI也可以称为第一DCI。具体地，所述第一DCI既可以用于指示所述终端设备在上行控制信道上发送所述A-CSI，还可以用于调度下行数据，所述下 行数据对应的反馈信息可以与所述A-CSI联合反馈或者单独反馈。其中，A-CSI可以是指一个A-CSI报告(A-CSI report)，A-CSI包含的信息可以由该A-CSI的报告标识(report ID)规定。
在本申请实施例中，DCI调度的下行数据对应的反馈信息也可以简称为DCI对应的反馈信息，后文不再做说明。
在本申请的一个实施方式中，所述方法还包括：终端设备接收所述第一DCI，所述第一DCI用于指示所述终端设备在上行控制信道上发送所述A-CSI。
可选地，在本申请的一个实施方式中，所述方法还包括：所述终端设备在接收所述第一DCI之后，还从网络设备接收一个或多个DCI，所述一个或多个DCI用于指示所述终端设备联合发送所述DCI对应的反馈信息以及所述A-CSI对应的A-CSI报告。通过反复指示终端设备发送所述A-CSI报告，提升终端设备发送所述A-CSI的成功率。
本申请实施例中所述的上行控制信道可以是PUCCH，具体地，可以是sPUCCH，也可以是其他可以用于承载上述反馈信息和/或A-CSI等上行信息的控制信道，不做限定。
S302:当所述上行信息为第一反馈信息，所述终端设备确定所述第一反馈信息对应的第一上行控制信道资源；当所述上行信息包括A-CSI，所述终端设备确定所述上行信息对应的第二上行控制信道资源，其中，所述第一上行控制信道资源与所述第二上行控制信道资源不同。
S303：所述终端设备在所述第一上行控制信道资源上发送所述第一反馈信息或者在所述第二上行控制信道资源上发送所述上行信息。
具体地，上述第一反馈信息可以是指除了上述第一DCI以外的其他一个或多个DCI(本申请实施例中以“第二DCI”、“第三DCI”为例说明)调度的下行数据分别对应的反馈信息的集合。第一反馈信息可以包含在第一码本中。例如，终端设备可以从网络设备接收所述第二DCI，根据所述第二DCI接收该第二DCI调度的第二下行数据，根据第二下行数据的译码结果生成第二下行数据对应的反馈信息。终端设备还可以从网络设备接收所述第三DCI，根据所述第三DCI接收该第三DCI调度的第三下行数据，根据第三下行数据的译码结果生成第三下行数据对应的反馈信息，则所述第一反馈信息可以包括所述第二下行数据对应的反馈信息以及第三下行数据对应的反馈信息。在一个示例中，终端设备可以一直尝试接收DCI，直到某个时间点，例如上行时隙n之前的第N个符号(n，N均为正整数)，在该时间点之后，UE仍然保持接收DCI，且UE可以开始准备在上行时隙n上发送在在该时间点之前接收到的DCI对应的上行信息，例如上述第一反馈信息。
本申请实施例中所述的上行控制信道资源是指上行控制信道所使用的传输资源。在本申请中，在上行控制信道资源上发送信息也可以理解为在上行控制信道上发送信息。
其中，所述第一上行控制信道资源与所述第二上行控制信道资源不同包括：至少一个资源维度上两个传输资源取值不完全相同，例如可以包括：时域上两个资源占据的时域符号不同、频域上两个资源占据的子载波或资源块(radio block，RB)不同、码域上两个资源占据的码道(如序列的循环移位或者正交掩码的取值)不同中的一种或多种情况。换言之，所述第一上行控制信道与所述第二上行控制信道可以使用不同的传输资源。
可选地，在本申请的一个实施方式中，所述终端设备在所述第二上行控制信道资源上发送所述上行信息包括：所述终端设备在所述第二上行控制信道资源上发送所述A-CSI以及所述第二反馈信息。可选地，所述第二反馈信息与所述A-CSI为同一个DCI指示。
可选地，在本申请的一个实施方式中，所述终端设备在所述第二上行控制信道资源上发送所述上行信息包括：所述终端设备在所述第二上行控制信道资源上发送所述A-CSI、所述第一反馈信息以及第二反馈信息。可选地，所述第二反馈信息与所述A-CSI为同一个DCI指示。
其中，在所述第二上行控制信道资源上发送的反馈信息(例如，上述第二反馈信息和/或第一反馈信息)可以包括在第二码本中，第二码本与前述第一码本不相同。
可选地，在本申请的一个实施方式中，所述终端设备在所述第二上行控制信道资源上发送所述上行信息包括：所述终端设备在所述第二上行控制信道资源上发送所述A-CSI以及所述第一反馈信息。
在一个示例中，当承载所述A-CSI的上行控制信道与承载反馈信息的上行控制信道在时域上重叠，且满足预设条件，则A-CSI与反馈信息可以在同一上行控制信道资源上进行联合反馈，即A-CSI与反馈信息在同一上行控制信道资源上发送，联合反馈的类型可以包括图2(a)以及图2(b)两类，不做赘述。其中，所述反馈信息可以包括所述第一DCI对应的反馈信息以及除了所述第一DCI之外的其他一个或多个DCI(例如前述“第二DCI”、“第三DCI”)调度的下行数据分别对应的反馈信息，例如在图2(a)场景下，所述第二反馈信息是触发所述A-CSI的DCI(即上述第一DCI)调度的下行数据所对应的反馈信息，即所述第二反馈信息与所述A-CSI为同一个DCI指示的，而所述第一反馈信息是另一个DCI(例如前述“第二DCI”)调度的下行数据所对应的反馈信息，由于承载所述第一反馈信息和第二反馈信息的上行控制信道与承载所述A-CSI的上行控制信道时域重叠，所述A-CSI与所述第一反馈信息、第二反馈信息联合编码；或者，所述反馈信息可以包括除了所述第一DCI之外的其他一个或多个DCI(例如前述“第二DCI”、“第三DCI”)调度的下行数据分别对应的反馈信息，例如在图2(b)场景下，所述反馈信息可以是除了所述第一DCI之外的其他一个或多个DCI分别对应的反馈信息，即所述第一反馈信息，所述第一反馈信息与所述A-CSI联合编码。
可选地，所述预设条件包括：承载所述A-CSI的上行控制信道与承载所 述反馈信息的上行控制信道的最早起始符号距离承载所述第一DCI的下行控制信道结束符号的距离大于或等于第一门限；和/或，承载所述A-CSI的上行控制信道与承载所述反馈信息的上行控制信道的最早起始符号距离所述反馈信息对应的下行数据信道的结束符号的距离大于或等于第二门限，其中，所述第一门限和第二门限可以是高层配置的或预定义的。
以反馈信息为ACK/NACK，上行控制信道为PUCCH为例说明上述第一码本与第二码本的生成与发送。在该示例中，终端设备可以从网络设备分别接收所述第一DCI、第二DCI以及第三DCI，其中，所述第一DCI指示终端设备反馈A-CSI并调度第一下行数据，第二DCI调度第二下行数据，第三DCI调度第三下行数据。终端设备根据所述第一下行数据生成第一ACK/NACK，根据所述第二下行数据生成第二ACK/NACK，且根据所述第三下行数据生成第三ACK/NACK。若所述终端设备没有成功接收第一DCI，例如，终端设备漏检所述第一DCI，终端设备确定上行信息为第一反馈信息，即包括第二ACK/NACK与第三ACK/NACK对应的第一码本，进而，终端设备可以在第一PUCCH资源上发送所述第一码本；当终端设备成功接收第一DCI，例如，终端设备没有漏检第一DCI，终端设备确定上行信息为A-CSI、第一反馈信息和第二反馈信息，即包括第一ACK/NACK、第二ACK/NACK、第三ACK/NACK对应的第二码本以及第一DCI指示的A-CSI，进而，终端设备可以在第二PUCCH资源上发送所述第二码本以及所述A-CSI，其中，所述第一PUCCH资源与所述第二PUCCH资源不同。
可选地，当所述A-CSI被设置为单独反馈，或者终端设备接收到的DCI调度了空数据，所述上行信息可以仅包含所述A-CSI，所述第二上行控制信道资源可以仅用于承载/发送所述A-CSI。
当所述终端设备向网络设备发送所述上行信息之后，所述方法还包括：
S304：所述网络设备确定所述上行信息使用的上行控制信道资源。
S305：所述网络设备接收所述上行信息。
具体地，网络设备在所述第一上行控制信道资源或第二上行控制信道资源上进行能量检测或序列检测或其他不依赖解调/解码的盲检测，确定终端设备使用了哪一个上行控制信道资源，若检测出第一上行控制信道资源，表示所述上行信息不包含A-CSI，则网络设备可以按照接收反馈信息的方式接收所述上行信息；若检测出第二上行控制信道资源，表示所述上行信息包含A-CSI，则网络设备可以按照接收反馈信息与A-CSI的方式接收所述上行信息。接收所述上行信息的具体方式可以采用任意一种接收方式，例如网络设备根据终端设备反馈的UCI的比特数目来进行上行信息接收，不做限定。
采用本申请实施例提供的通信方法，终端设备采用第一上行控制信道资源发送反馈信息，采用第二上行控制信道资源发送包含A-CSI的上行信息(例如，A-CSI以及反馈信息)，其中，所述第一上行控制信道资源与所述第二上行控制信道资源不同，从而，网络设备通过接收到的上行信息使用的控制 信道资源识别所述上行信息是否包含A-CSI，能够对上行信息进行正确接收，且无需多次盲检，接收复杂度低。
图4-图8所示实施方式是在图3所示实施例的基础上，对本申请提供的通信方法的详细说明，其中，图4-图8所示实施方式分别列举了几类如何确定承载包含A-CSI的上行信息的上行控制信道资源(如上述第二上行控制信道资源)与承载反馈信息的上行控制信道资源(如上述第一上行控制信道资源)的具体方式，可以理解，本申请提供的各个实施方式之间可以相互参考，前文已述的内容将不再重复说明。
在本申请的一个实施方式中，网络设备为终端设备配置两组不同的上行控制信道资源集，承载包含A-CSI的上行信息的上行控制信道资源与承载反馈信息的上行控制信道资源分别从上述两组资源集中选择。如图4所示，所述方法包括：
S401：终端设备从网络设备接收第一指示信息，所述第一指示信息用于指示第一组上行控制信道资源集，所述第一组上行控制信道资源集包括至少一个上行控制信道资源集。
为了表述简洁，下文将“上行控制信道资源集”简称为“资源集”，“第一组上行控制信道资源集”简称为“第一组资源集”，“第二组上行控制信道资源集”简称为“第二组资源集”。
其中，所述第一组资源集中的每个资源集对应(或称为映射)一个信息负载区间，所述信息负载区间是指该资源集中的上行控制信道资源所能承载的信息的比特数目的范围，其中，所述负载大小可以用UCI的比特数目(N UCI)表征。同一组资源集中的各个资源集对应的信息负载区间不重叠(或者说没有交集)。同一组资源集中的资源集对应的信息负载区间可以由小到大排列。
为了方便描述，本申请中将例如反馈信息和/或A-CSI等上行信息对应的UCI的比特数目简称为上行信息的比特数目。
S402：所述终端设备从网络设备接收发送第二指示信息，所述第二指示信息用于指示第二组资源集，所述第二组资源集包括至少一个资源集。
类似上述第一组资源集，所述第二组资源集中的每个资源集对应一个信息负载区间，且各个资源集对应的信息负载区间不重叠且可以由小到大排列，不做赘述。
所述第一组资源集与所述第二组资源集中至少有一个资源集不同。具体地，所述资源集不同可以是指资源集中的资源不同或者资源集包含的资源排列不同，例如两个资源集包含的资源完全不同或者部分不同，或者包含的资源相同但是排列顺序不同。由于所述第一组资源集与所述第二组资源集不完全重叠(可以有交集)或完全不重叠(没有交集)，因此可以视为两组不同的资源集。
在该实施方式中，以所述第一组资源集对应反馈信息，以所述第二组资 源集对应反馈信息与A-CSI为例进行说明。可以理解，在实际应用中，网络设备与终端设备预先可以约定具体哪一组资源集对应反馈信息，且另一组资源集对应反馈信息与A-CSI，不做限定。
其中，S401与S402没有执行的先后顺序限制，可以先执行S401再执行S402；也可以先执行S402再执行S401，也可以同时执行S401及S402，不做限定。
可选地，在本申请的另一个实施方式中，上述第一指示信息或第二指示信息可以是预定义的。终端设备可以直接从本地获取所述第一指示信息或第二指示信息，而不用从网络设备接收。
可选地，所述方法还包括S403：所述终端设备接收第三指示信息，所述第三指示信息用于指示所述第一组资源集中每一个资源集对应的信息负载区间。
可选地，所述方法还包括SS404：所述终端设备接收第四指示信息，所述第四指示信息用于所述第二组资源集中每一个资源集对应的信息负载区间。
其中，所述第三指示信息与所述第四指示信息可以是同一个指示信息。
可选地，上述第一指示信息至第四指示信息中的任意一个是所述网络设备配置的高层参数。
其中，S403与S404没有执行的先后顺序限制，可以先执行S403再执行S404；也可以先执行S404再执行S403，也可以同时执行S403及S404，不做限定。S405：所述网络设备向所述终端设备发送第一DCI，所述第一DCI用于调度第一下行数据并触发A-CSI反馈。
其中，所述第一DCI中可以包含第一定时指示信息，所述第一定时指示信息用于指示所述第一下行数据对应的反馈信息和所述A-CSI在第一时间单元内反馈。
S406：所述网络设备向所述终端设备发送第二DCI，所述第二DCI用于调度第二下行数据。
其中，所述第二DCI中可以包含第二定时指示信息，所述第二定时指示信息用于指示所述第二下行数据对应的反馈信息在所述第一时间单元内反馈。
为了便于说明，下文将所述第一下行数据对应的反馈信息称为反馈信息A；将所述第二下行数据对应的反馈信息称为反馈信息B。
根据上述第一DCI以及第二DCI，可知，用于承载反馈信息A的上行控制信道与用于承载A-CSI的上行控制信道在时域上有重叠。
可以理解，上述第一DCI是指示终端设备反馈A-CSI的DCI，而第二DCI是普通的用于调度下行数据传输的DCI。本申请实施例以第一DCI、第二DCI为例进行说明，并不限定不同类型的DCI的数量，例如用于调度下行数据的DCI(第二DCI)可以有多个，或者说，网络设备可以向终端设备发 送多个与第二DCI同类型的DCI，所述与第二DCI同类型的DCI是指用于调度下行数据，且调度的下行数据对应的反馈信息与所述第一DCI对应的反馈信息以及A-CSI在同一个时间单元(例如，上述第一时间单元)内发送的DCI。当有多个第二DCI时，终端设备确定的上行信息中可以包含多个反馈信息，例如多个ACK/NACK，所述多个ACK/NACK可以包含在同一码本中。
在本申请实施例中假定第二DCI可以被终端成功接收，而第一DCI可能未被成功接收(例如漏检)。
其中，S405与S406没有执行的先后顺序限制，可以先执行S405再执行S406；也可以先执行S406再执行S405，也可以同时执行S405及S406，不做限定。且S405-S406与S401-S402/S401-S404也没有执行的先后顺序限制，不做限定，例如终端设备可以先接收指示资源集的指示信息再接收DCI，即先执行S401-S402/S401-S404再执行S405-S406。
S407：终端设备确定向所述网络设备反馈的上行信息。
所述终端设备可以根据所述第二DCI接收所述第二下行数据，且根据第二下行数据的译码结果生成所述反馈信息B。所述终端设备尝试接受所述第一DCI，当所述第一DCI未被成功接收，而第二DCI被接收，所述终端设备确定所述上行信息为所述反馈信息B，且所述反馈信息B可以包含在一个码本中；当所述第一DCI被成功接收，所述终端设备根据所述第一DCI接收所述第一下行数据，且根据第一下行数据的译码结果生成所述反馈信息A，所述终端设备确定所述上行信息包括所述A-CSI。例如，所述上行信息可以包括所述A-CSI以及所述反馈信息A、反馈信息B，其中，反馈信息A与反馈信息B可以包含在另一个码本中。
S408：终端设备确定承载所述上行信息的上行控制信道资源。
S409：终端设备在所述上行控制信道资源上向网络设备发送所述上行信息。
所述终端设备可以根据上行信息的内容确定上行信息对应的资源集组以及资源集，进而在资源集中确定上行资源。例如，承载反馈信息B的上行控制信道资源B属于第一资源集，且所述第一资源集属于所述第一组资源集；承载包括所述反馈信息A、反馈信息B和所述A-CSI的上行信息的上行控制信道资源A属于第二资源集，且所述第二资源集属于所述第二组资源集。其中，所述第一资源集与所述第二资源集不同。在一个示例中，终端设备从所述第一组资源集与所述第二组资源集中分别选择一个资源集，且选择出的两个资源集不同。
具体地，当终端设备确定上行信息为反馈信息B，则上行信息对应第一组资源集；进而，终端设备根据反馈信息B的比特数目，从所述第一组资源集中确定与反馈信息B的比特数目映射的资源集为目标资源集。当终端设备确定上行信息包括A-CSI以及反馈信息A、反馈信息B时，则上行信息对应第二组资源集，进而，终端设备根据反馈信息A、反馈信息B与A-CSI的比 特数目之和，或者根据反馈信息A、反馈信息B对应的码本与A-CSI的比特数目之和，从第二组资源集中确定与所述比特数目之和对应的资源集为目标资源集。
当确定目标资源集之后，终端设备根据所述第一DCI与所述第二DCI中后接收到的DCI，或者当终端设备接收到多个与第二DCI同类型的DCI，则终端设备按照最后接收到的DCI中的资源指示信息，例如ARI，从该目标资源集中确定该资源指示信息指示的上行控制信道资源为承载所述上行信息的资源。
在一个示例中，将所述第一组资源集记为group1，将所述第二组资源集记为group2，group1中包含3个资源集，记为{set0，set1，set2}，其中，set0对应的信息负载区间为[1,2]，set1对应的信息负载区间为[3,11]，set2对应的信息负载区间为[12,1706]；group2中包含3个资源集，记为{set3，set4，set5}，其中，set3对应的信息负载区间为[1,2]，set4对应的信息负载区间为[3,11]，set5对应的信息负载区间为[12,1706]，且set0至set5中各包含8个上行控制信道资源，假设set0中的上行控制信道资源与set3中的上行控制信道资源的排列顺序不同，即set0与set3为不同的资源集。当第一DCI未成功接收，则终端设备可以在group1中根据第二DCI对应的反馈信息B的比特数目选择资源集，例如假设反馈信息B的比特数目为4，则终端设备确定承载该反馈信息的上行控制信道资源从set1中选取。当第一DCI成功接收，则终端设备可以在group2中根据第一DCI对应的反馈信息A以及A-CSI的比特数目之和选择资源集，例如反馈信息A以及A-CSI的比特数目之和为11，则终端设备确定承载该反馈信息的上行控制信道资源从set4中选取。可选地，每一组资源集中的资源集对应的信息负载区间为从小到大排列。
以上行信息包括ACK/NACK与A-CSI，上行控制信道为PUCCH为例，说明终端设备如何选择PUCCH资源承载所述上行信息。具体地，终端设备可以根据ACK/NACK对应的码本确定需要反馈的ACK/NACK的比特数目，并确定A-CSI的比特数目，然后在对应于ACK/NACK与A-CSI的一组资源集(例如，上述第二组资源集)中选择一个对应于所述ACK/NACK与A-CSI的比特数目之和的PUCCH资源集，所述PUCCH资源集中可以包含最少8个、最多32个PUCCH resource。进而，终端设备可以根据接收到的最后一个对应于所述ACK/NACK对应的码本的DCI中的ARI确定反馈该码本的PUCCH资源是上述PUCCH资源集中的哪一个资源。其中，所述PUCCH资源集可以被分为多个资源子集(subset)，由ARI指示选择哪个资源子集，并利用PDCCH的起始控制信道粒子(Control Channel Element,CCE)索引来隐式指示选择ARI指示的资源子集中的具体的某个资源。
在该实施方式中，采用高层配置或者预定义上述第一组资源集以及第二组资源集的方式，效率高，对终端设备与网络设备的通信过程影响小。
在本申请的一个实施方式中，承载包含A-CSI的上行信息的上行控制信道资源所属的资源集与该上行信息的信息负载之间的映射关系(映射关系A)，和承载反馈信息的上行控制信道所属的资源集与该反馈信息的信息负载之间的映射关系(映射关系B)不同。所述方法包括：
S501：终端设备从网络设备接收第一指示信息，所述第一指示信息用于指示第一组资源集，所述第一组资源集包括至少一个资源集。
其中，所述第一组资源集中的每个资源集对应一个信息负载区间，且各个资源集对应的信息负载区间不重叠，且同一组资源集中的各资源集对应的信息负载区间可以从小到大排列。具体可以参照S401中的描述，不做赘述。
S502：所述终端设备从所述网络设备接收第二指示信息，所述第二指示信息用于指示一个资源集(为了便于说明，下文称为“资源集N”)，所述资源集N与所述第一组资源集中的任意一个资源集不相同。
可选地，在一个实施方式中，所述资源集N对应的信息负载区间等于所述第一组资源集中的最后一个资源集对应的信息负载区间。例如，假设所述第一组资源集中包含3个资源集，记为{set0，set1，set2}，其中，set0对应的信息负载区间为[1,2]，set1对应的信息负载区间为[3,11]，set2对应的信息负载区间为[12,1706]，则资源集N对应的信息负载区间可以为[12,1706]。
其中，S502为可选的步骤，当S501与S502都执行时，两个步骤没有执行的先后顺序区分。
可选地，所述方法还包括S503：所述终端设备从所述网络设备接收第三指示信息，所述第三指示信息用于指示所述第一组资源集中每一个资源集对应的信息负载区间。
S504：所述网络设备向所述终端设备发送第一DCI，所述第一DCI用于调度第一下行数据并触发A-CSI反馈。
其中，所述第一DCI中可以包含第一定时指示信息，所述第一定时指示信息用于指示所述第一下行数据对应的反馈信息和所述A-CSI在所述第一时间单元内反馈。
S505：所述网络设备向所述终端设备发送第二DCI，所述第二DCI用于调度第二下行数据。
其中，所述第二DCI中可以包含第二定时指示信息，所述第二定时指示信息用于指示所述第二下行数据对应的反馈信息在第一时间单元内反馈。
其中，S504与S505没有执行的先后顺序限制，可以先执行S504再执行S505；也可以先执行S505再执行S504，也可以同时执行S504及S505，不做限定。此外，S501与S504、S505也没有执行的先后顺序限制，不做赘述。
关于第一DCI、第二DCI的更多说明可以参照图4所示实施方式中的相关内容，不做赘述。
其中，所述第一下行数据对应的反馈信息称为反馈信息A，所述第二下行数据对应的反馈信息称为反馈信息B。
S506：终端设备确定向所述网络设备反馈的上行信息。
当所述第一DCI未被成功接收，所述终端设备确定所述上行信息为所述反馈信息B；当所述第一DCI被成功接收，所述终端设备确定所述上行信息包括所述A-CSI，例如包括所述A-CSI以及所述反馈信息A、反馈信息B，关于确定上行信息的具体过程可以参照S407中的描述，不做赘述。
S507：终端设备确定承载所述上行信息的上行控制信道资源。
S508：终端设备在所述上行控制信道资源上向网络设备发送所述上行信息。
具体地，承载反馈信息B的上行控制信道资源可以从所述第一组资源集中的资源集选取；承载包含反馈信息A、反馈信息B以及A-CSI的上行信息的上行控制信道资源可以从所述第一组资源集中的资源集选取或者从所述资源集N中选取。包含反馈信息A、反馈信息B以及A-CSI的上行信息对应的资源集与所述反馈信息A、反馈信息B以及A-CSI的信息负载之和存在映射关系A，所述反馈信息B对应的资源集与所述反馈信息B的信息负载存在映射关系B，且映射关系A与映射关系B不同。其中，所述信息负载可以用比特数目表征。
当终端设备确定上行信息为反馈信息B，终端设备可以根据反馈信息B的比特数目，从所述第一组资源集中确定与反馈信息B的比特数目映射的资源集为目标资源集。当终端设备确定上行信息包括A-CSI以及反馈信息A、反馈信息B时，终端设备首先根据反馈信息B对应的码本B的比特数，从所述第一组资源集中确定与码本B的比特数目映射的资源集B，再根据反馈信息A与反馈信息B对应的码本A的比特数目与所述A-CSI的比特数目之和，从所述第一组资源集中确定与码本A与所述A-CSI的比特数目之和映射的资源集A。其中，资源集A与资源集B可能相同或不相同。
当码本B的比特数目对应的信息负载区间与所述A-CSI与码本A的比特数目之和对应的信息负载区间不同，则资源集B与资源集A是不同的资源集，终端设备可以将资源集A确定为目标资源集。
由于资源集对应的是信息负载区间，因此，即使码本B的比特数目不同于所述A-CSI与码本A的比特数目之和，若两者对应到同一信息负载区间，则资源集A和资源集B可以是同一个资源集。在这种情况下，终端设备可以调整所述A-CSI与码本A对应的资源集。
具体地，终端设备可以将所述A-CSI与码本A的比特数目之和映射的资源集调整为更大负载区间对应的资源集，该新资源集可以称为资源集C。此时资源集C对应的信息负载区间大于所述资源集A对应的信息负载区间。终端设备可以将资源集C作为目标资源集。可选地，资源集C对应的信息负载区间是大于所述资源集A对应的信息负载区间的一个或多个信息负载区间中最小的，换言之，资源集C是对应的信息负载区间大于资源集A的资源集中对应的信息负载区间最小一个的资源集。
在一个示例中，假设所述第一组资源集为{set0，set1，set2，set3}，其中，set0对应的信息负载区间为[1,2]，set1对应的信息负载区间为[3,11]，set2对应的信息负载区间为[12,100]，set3对应的信息负载区间为[101,1076]，可以理解，set0至set3对应的信息负载区间依次递增。若终端设备确定上行信息为反馈信息B，且确定反馈信息B的比特数目为3，则承载反馈信息B的上行控制信道资源从set1中选择；若终端设备确定上行信息包含A-CSI以及反馈信息A、反馈信息B，且确定三者的比特数目之和为11，按照预设的映射关系，比特数目11可以映射到set1，即承载上行信息的资源原本从set1中选择，为了避免承载反馈信息B的上行控制信道资源与承载包含A-CSI的上行信息的上行控制信道资源从同一资源集(例如set1)中选取，终端设备可以调整比特数目与资源集的映射关系，将比特数目11映射到对应的信息负载区间比set1对应的信息负载区间更大的资源集，例如映射到set2或set3，即终端设备可以将set2或set3确定为资源集C，进而，终端设备从set2或set3中选择上行控制信道资源承载包含A-CSI的上行信息。可选地，由于set2的信息负载区间大于set1的信息负载区间且小于set3的信息负载区间，终端设备可以将set2确定为资源集C，由于set2的信息负载区间是大于set1的信息负载区间中最小的，从set2中选择出的上行控制信道资源的大小相对较小，从而能够节约传输资源，对终端设备与网络设备的通信过程影响小，进一步提升通信质量。
可选地，当所述第一组资源集包含M个资源集(M为正整数)，且资源集B为M个资源集中对应信息负载区间最大的资源集时，终端设备确定目标资源集为所述第一组资源集之外的一个新的资源集，例如，为上述资源集N。在一个示例中，假设所述第一组资源集为{set0，set1，set2}，资源集N为set3，其中，set0对应的信息负载区间为[1,2]，set1对应的信息负载区间为[3,11]，set2与set3对应的信息负载区间分别为[12,1706]，若终端设备确定上行信息为反馈信息B，且确定反馈信息B的比特数目为13，则承载反馈信息B的上行控制信道资源从set2中选择；若终端设备确定上行信息包含A-CSI以及反馈信息A、反馈信息B，且确定三者的比特数目之和为25，则承载上行信息的资源原本从set2中选择，但终端设备可以调整映射关系，将比特数目25映射到set3，从set3中选择上行控制信道资源承载包含A-CSI的上行信息。
当确定目标资源集之后，终端设备可以根据所述第一DCI与所述第二DCI中后接收到的DCI(即终端设备最后接收到的DCI)中的资源指示信息，从该目标资源集中确定该资源指示信息指示的上行控制信道资源来承载所述上行信息，可以参照图3-4所示实施例中的相关描述，不做赘述。
在本申请的一个实施方式中，承载包含A-CSI的上行信息的上行控制信道资源与承载反馈信息的上行控制信道资源由不同的DCI指示。该方法包括：
S601：网络设备向所述终端设备发送第一DCI，所述第一DCI用于调度第一下行数据并触发A-CSI反馈。
可选地，所述第一DCI包含资源指示信息A，资源指示信息A用于指示上行控制信道资源A。
所述第一DCI中还可以包含第一定时指示信息，所述第一定时指示信息用于指示所述第一下行数据对应的反馈信息和所述A-CSI在所述第一时间单元内反馈。
S602：所述网络设备向所述终端设备发送第二DCI，所述第二DCI用于调度第二下行数据。
可选地，所述第二DCI包含资源指示信息B，资源指示信息B用于指示上行控制信道资源B。
所述第二DCI中还可以包含第二定时指示信息，所述第二定时指示信息用于指示所述第二下行数据对应的反馈信息在第一时间单元内反馈。
其中，所述第一DCI与所述第二DCI为不同的DCI。在本申请的一个实施方式中，所述第二DCI在所述第一DCI之后发送/接收或同时发送/接收，或者说，所述第二DCI晚于/不早于所述第一DCI。具体地，在单载波场景下，所述第二DCI晚于/不早于第一DCI可以是指第二DCI所在的第二监控时机晚于/不早于第二DCI所在的第一监控时机。可选地，所述第二监控时机晚于/不早于所述第一监控时机是指第二监控时机的起始符号晚于/不早于第一监控时机的起始符号。在多载波场景下，所述第二DCI晚于/不早于第一DCI可以是指第二DCI所在的第二监控时机晚于/不早于第二DCI所在的第一监控时机，或者，当第一DCI与第二DCI位于相同的监控时机时，第二DCI所在载波编号大于/不小于第一DCI所在载波编号。其中，监控时机可以是例如PDCCH时机(PDCCH occasion)。
关于第一DCI、第二DCI的更多说明可以参照图4所示实施方式中的相关内容，不做赘述。
其中，所述第一下行数据对应的反馈信息称为反馈信息A，所述第二下行数据对应的反馈信息称为反馈信息B。
资源指示信息A与资源指示信息B指示了两个不同的上行控制信道资源。其中，所述上行控制信道资源A用于承载包括所述A-CSI的上行信息，所述上行信息还可以包括所述反馈信息A和/或反馈信息B。所述上行控制信道资源B用于承载所述反馈信息B。
可选地，第一资源指示信息A或第二资源指示信息B是ARI。
S604：终端设备确定向所述网络设备反馈的上行信息。
当所述第一DCI未被成功接收，所述终端设备确定所述上行信息为所述反馈信息B；当所述第一DCI被成功接收，所述终端设备确定所述上行信息包括所述A-CSI，关于确定上行信息的具体过程可以参照S407中的描述，不做赘述。
S604：终端设备确定承载所述上行信息的上行控制信道资源。
S605：终端设备在所述上行控制信道资源上向网络设备发送所述上行信息。
具体地，当所述第一DCI未被成功接收，终端设备根据第二DCI中的资源指示信息B确定所述上行控制信道资源B；当UE成功接收第一DCI后，终端设备根据第一DCI中的资源指示信息A确定所述上行控制信道资源A。
可以理解，在接收所述第一DCI之前或之后，所述终端设备还可以接收一个或多个用于调度下行数据的DCI，例如，在接收所述第一DCI之前，所述终端设备可以接收用于调度第三下行数据的第三DCI，且所述第三DCI中包含用于指示在所述第一时间单用内发送第三反馈信息的第三定时指示信息，则当所述第一DCI被成功接收，所述第三下行数据对应的反馈信息(以下称为反馈信息C)可以与所述第一DCI调度的A-CSI联合反馈，在所述上行控制信道资源A上发送，且所述反馈信息A、反馈信息B、反馈信息C可以包含在同一码本(码本C)中；当所述第一DCI未被成功接收，则所述反馈信息C可以在所述上行控制信道资源B上发送，且反馈信息C与所述反馈信息B可以包含在另一码本(码本D)中。
可选地，所述第二DCI为终端设备接收到的最后一个对应于所述上行控制信道资源B承载的反馈信息(例如上述反馈信息B及反馈信息C)的DCI，或者说，所述第二DCI为所述终端设备按时序和/或载波编号接收的第N个对应于对应于所述上行控制信道资源B承载的反馈信息的DCI，所述上行控制信道资源B承载的反馈信息对应N个DCI(N为正整数)。其中，按载波编号接收DCI可以适用于多载波场景。具体地，当所述终端设备在所述第一DCI之后，接收包括所述第二DCI在内的多个与所述第二DCI同类型的DCI，则所述第二DCI是终端设备接收到多个该类型的DCI中的最后一个DCI，且第二DCI同类型的DCI对应的反馈信息可以包含在同一码本中。例如，上述码本D中包括反馈信息B与反馈信息C，且反馈信息B由所述第二DCI指示发送，反馈信息C由所述第三DCI指示，第二DCI可以在第三DCI之后被接收。
可选地，承载包含A-CSI的上行控制信道资源由终端设备接收到的最晚的DCI中的资源指示信息指示，且该资源指示信息指示的控制信道资源与之前DCI指示的承载反馈信息的上行控制信道资源不同。具体地，所述终端设备接收到所述第一DCI后，不期望接收第四DCI，所述第四DCI不触发A-CSI反馈，且所述第四DCI对应的反馈信息所使用的上行控制信道资源与所述上行控制信道资源A在时域上重叠。或者说，所述终端设备接收到所述第一DCI后，接收到的DCI对应的反馈信息所使用的上行控制信道资源与所述上行控制信道资源A在时域上不重叠，其中不重叠是指完全不重叠，或者说不相邻也没有交集。则所述第一DCI是终端设备接收到的、指向所述上行控制信道资源所在时间单元最晚的DCI，例如所述第一DCI不早于前述第四DCI。 可选地，所述第一DCI所在的监控时机晚于所述第四DCI所在的监控时机；或者，当所述第一DCI所在的监控时机与所述第四DCI所在的监控时机相同，且所述第一DCI所在的载波编号大于所述第四DCI所在的载波编号。
终端设备对在所述第一DCI之后接收到的DCI进行接收和解码。若终端设备对接收到的DCI解码后发现该DCI对应的反馈信息在与承载A-CSI的上行控制信道资源重叠的另一上行控制信道资源上发送(例如上述第四DCI)，则终端设备不对该DCI调度的数据进行译码，不发送该数据的反馈信息，或者将该数据的反馈信息设置为NACK。例如，若高层配置半静态码本反馈模式，终端设备将该DCI对应的反馈信息设置为NACK，当高层配置动态码本反馈模式，终端设备不发送该DCI对应的反馈信息。若终端设备对接收到的DCI解码后发现该DCI对应的反馈信息所在的上行控制信道资源在与承载A-CSI的上行控制信道资源未重叠，则终端设备按照正常流程进行ACK/NACK反馈。
在本申请的另一个实施方式中，所述第一DCI与所述第二DCI没有发送/接收的顺序限制，即S601与S602没有执行的先后顺序限制。在该实施方式中，当所述第一DCI未被成功接收，所述终端设备确定所述上行信息为所述反馈信息B；当所述第一DCI被成功接收，所述终端设备确定所述上行信息包括所述A-CSI，例如包括所述A-CSI以及所述反馈信息A。当第一DCI被成功接收，所述终端设备可以根据第一DCI中的资源指示信息A确定所述上行控制信道资源A，在所述上行控制信道资源A上发送所述反馈信息A对应的码本E与所述A-CSI，在所述上行控制信道资源B上发送所述反馈信息B对应的码本F，且码本E不包含反馈信息B，码本F不包含反馈信息A。当所述第一DCI未被成功接收，所述终端设备可以根据第二DCI中的资源指示信息B确定所述上行控制信道资源B，在所述上行控制信道资源B上发送所述反馈信息B对应的码本F，其中，码本F不包含反馈信息A。当码本F为半静态码本时，码本B中与反馈信息A对应的比特位置可以设置为NACK。当码本F为动态码本时，进行DAI计数时可以跳过所述第一DCI，以节约资源。在该实施方式中，网络设备为包含A-CSI的上行信息单独指示上行控制信道资源，且由终端设备确定该上行信息不与触发所述A-CSI的DCI之外的其他DCI对应的反馈信息联合传输，因此，网络设备侧不会对上行信息的比特数目理解错误，从而能够正确接收上行信息。
在本申请的一个实施方式中，在触发A-CSI的DCI(第一DCI)之后发送的DCI，即使该DCI没有触发A-CSI，也可以启用该DCI中的CSI request字段，触发与第一DCI相同的A-CSI报告。该方法包括：
S701：网络设备向终端设备发送第一DCI，所述第一DCI用于调度第一下行数据并触发A-CSI反馈。
其中，所述第一DCI具体可以用于指示所述终端设备向所述网络设备发送A-CSI报告。
所述第一DCI中可以包括第一定时指示信息，用于指示所述第一下行数据对应的反馈信息和所述A-CSI在所述第一时间单元内反馈。所述第一DCI中还可以包括资源指示信息A，用于指示上行控制信道资源A。
S702：网络设备向终端设备发送第二DCI，所述第二DCI用于调度第二下行数据并指示所述终端设备发送所述A-CSI报告。
所述第二DCI中包括第二定时指示信息，用于指示所述第二下行数据对应的反馈信息和所述A-CSI在所述第一时间单元内反馈。所述第二DCI中还可以包括资源指示信息B，用于指示上行控制信道资源B。
其中，所述第二DCI晚于所述第一DCI发送。
所述第二DCI可以用于指示所述终端设备联合发送所述第二下行数据的反馈信息以及所述A-CSI报告。可选地，可以通过第一DCI或者第二DCI中的CSI字段触发所述A-CSI报告，所述CSI字段可以是CSI Request字段。该CSI Request字段可以是多比特，不同取值可以指示不同的A-CSI报告，例如CSI request＝00指示不触发，CSI request＝01指示触发所述A-CSI报告。
在该实施方式中，在发送所述第二DCI后，网络设备发送的任一DCI要么触发所述A-CSI报告，要么对应的反馈信息不在所述第一时间单元内反馈，即其他DCI对应的反馈信息使用的上行控制信道与A-CSI使用的上行控制信道不重叠。
关于第一DCI、第二DCI的更多说明可以参照图4所示实施方式中的相关内容，不做赘述。
S703：终端设备确定向所述网络设备反馈的上行信息。
终端设备尝试接收所述第一DCI与第二DCI。当第一DCI接收成功时，终端设备可以忽略第二DCI触发的A-CSI报告，而所述上行信息的具体内容可以根据终端设备接收到的最后的DCI确定，例如若第二DCI接收成功，则按照第二DCI确定；若第二DCI接收失败，则按照第一DCI确定。
具体地，当第一DCI接收成功，且第二DCI接收失败，终端设备可以根据所述第一DCI确定在所述第一时间单元上发送所述A-CSI报告，所述上行信息可以包括所述A-CSI以及所述第一DCI对应的反馈信息。当所述第一DCI接收成功，且第二DCI接收成功时，终端设备可以根据所述第一DCI确定在所述第一时间单元上发送所述A-CSI报告，所述上行信息可以包括所述A-CSI、所述第一DCI对应的反馈信息以及所述第二DCI对应的反馈信息。
当所述第一DCI接收失败，且第二DCI接收成功时，终端设备可以根据所述第二DCI确定在所述第一时间单元上发送所述A-CSI报告。此时，所述上行信息可以包括所述A-CSI以及第二DCI对应的反馈信息。
当所述第一DCI与第二DCI均接收失败，终端设备可以确定所述上行信息包括在所述第一DCI之前接收的第三DCI对应的反馈信息。其中，所述第三DCI用于调度第三下行数据，且所述第三DCI中可以包括第三定时指示信息，用于指示所述第三下行数据对应的反馈信息在所述第一时间单元内反 馈。所述第三DCI中还可以包括第三资源指示信息，用于指示上行控制信道资源C，且所述上行控制信道资源C与所述上行控制信道资源A或所述上行控制信道资源B不同。可选地，所述第一DCI所在的监控时机晚于所述第三DCI所在的监控时机。
S704：终端设备确定承载所述上行信息的上行控制信道资源。
S705：终端设备在所述上行控制信道资源向网络设备发送所述上行信息。
具体地，当第一DCI接收成功且第二DCI未成功接收时，终端设备可以根据所述资源指示信息A确定上行控制信道资源A，并在所述上行控制信道资源A发送包含所述第一DCI对应的反馈信息的码本G以及所述A-CSI。
当第二DCI接收成功时，终端设备可以根据所述资源指示信息B确定上行控制信道资源B，并在所述上行控制信道资源B发送包含所述第二DCI对应的反馈信息的码本H以及所述A-CSI。
当第一DCI和第二DCI均未接收成功，终端设备可以根据接收到的其他DCI，例如上述第三DCI中的第三资源指示信息确定上行控制信道资源C，并在所述上行控制信道资源C上发送包含第三DCI对应的反馈信息的码本I。
其中，对于半静态码本，上述码本G、码本H、码本I的比特数都相同；对于动态码本，上述码本G、码本H、码本I的比特数目不同。
可选地，在多载波的场景下，终端设备可以只反馈主载波上的A-CSI，对于其他辅载波上触发的A-CSI报告都作为是对主载波上触发的A-CSI报告的重复。
利用该实施方式中的重复触发A-CSI报告的方式，可以提升终端设备成功接收触发A-CSI的DCI的概率，避免网络设备对于联合反馈的A-CSI与反馈信息接收错误。该实施方式可以与图3-图6所示的任一实施方式结合，也可以单独实施，即在该实施方式中，承载包括A-CSI的上行信息的上行控制信道资源与承载反馈信息的上行控制信道资源可以不同，也可以相同，不做限定。
为了描述简洁，上述图4-图7所示实施方式中主要描述了上行信息的确定以及发送过程，关于网络设备接收所述上行信息的过程可以参照图3所示实施例中的相关描述，例如步骤S304-S305，不做赘述。
上述图4-图7所示实施方式以联合反馈为例进行说明，如图2(a)场景。对于如图2(b)所示的单独反馈场景，终端设备也会接收用于触发A-CSI与调度下行数据的DCI，当承载A-CSI的上行控制信道与触发该A-CSI的DCI之外的其他DCI对应的反馈信息使用的上行控制信道在时域上重叠时，终端设备需要进行A-CSI与其他DCI对应的反馈信息的联合反馈，与图2(a)场景的区别在于在触发A-CSI的DCI对应的反馈信息不与A-CSI在同一上行控制信道资源上发送，因此，本申请实施例提供的通信方法也适用如图2(b)所示场景。例如，对于图4所示的实施方式，如果终端设备没有成功接收触 发A-CSI的DCI，则可以使用一组资源集来确定仅用于承载反馈信息B的上行控制信道资源，如果终端设备成功接收触发A-CSI的DCI，则使用另一组上行控制信道资源集来确定承载反馈信息B与A-CSI的上行控制信道资源，且两组资源集中至少有一个资源集不同，具体可以参照图4所示实施方式中的说明，区别在于如图2(b)所示场景中，反馈信息A，即触发A-CSI的DCI对应的反馈信息不与A-CSI位于同一上行控制信道资源，细节不做赘述。此外，本申请其他实施方式，例如图5-图7所示的实施方式，对于上述单独反馈场景也可以适用，具体实施方式与联合反馈场景下类似，不做赘述。
承载A-CSI的上行控制信道除了可能与承载反馈信息(例如ACK/NACK)的上行控制信道重叠，也有可能与上行数据信道重叠。当承载A-CSI的上行控制信道与上行数据信道重叠时，终端设备可以把A-CSI携带(piggyback)在上行数据信道上且使用速率匹配(rate-match)方式进行传输。然而，若终端设备未能成功接收指示所述A-CSI的DCI，例如漏检该DCI，则终端设备实际并未在上行数据信道上传输所述A-CSI，但网络设备仍然会按照A-CSI携带在所述上行数据信道上的情况进行接收，这就会造成网络设备对上行数据所在的资源位置估计错误，进而，数据接收会出现问题。其中，所述资源可以是资源粒子(resource element，RE)，资源位置可以是RE在时域和频域上的位置。
为了解决上述问题，本申请实施例提供了一种通信方法，可以在承载A-CSI的上行控制信道与上行数据信道重叠时，使得网络设备能够正确接收上行数据。图8是本申请实施例提供的一种通信方法的流程示意图。该方法包括：
S801：终端设备确定上行控制信道，所述上行控制信道用于承载第一A-CSI。
其中，所述上行控制信道可以是PUCCH或者其他用于承载上行信息的控制信道，不做限定。
可选地，终端设备接收第一DCI，所述第一DCI用于指示所述终端设备在上行控制信道上发送所述第一A-CSI，所述第一DCI还可以用于调度下行数据。关于所述第一DCI的详细说明可以参考本申请其他实施例中的相关描述，不做赘述。
S802：所述终端设备确定上行数据信道，所述上行数据信道用于承载上行数据和/或第二A-CSI，且所述上行控制信道与所述上行数据信道在时域上重叠。
其中，所述上行数据信道可以是物理上行共享信道(physical uplink shared channel，PUSCH)或者用于发送上行数据的信道，不做限定。所述上行数据信道可以是动态的(dynamic)或者配置的(configured)。其中，动态的上行数据信道也可以称为动态调度的上行数据信道，例如可以是由终端接收的第二DCI调度的，可选地，所述第二DCI还可以用于指示在所述上 行数据信道上发送第二A-CSI。此外，配置的上行数据信道包括不同的类型，以上行数据信道为PUSCH为例，配置的PUSCH可以为类型一(Type 1)，即包括免授权PUSCH(grant free PUSCH，GF PUSCH)，或者类型二(Type 2)，即半持续性调度PUSCH(Semi-Persistent Schduling SPS PUSCH)。
所述上行控制信道与所述上行数据信道在时域上重叠可以是指：所述第一A-CSI与所述上行数据和/或第二A-CSI在相同的时间单元上发送。
可以理解，S801与S802没有执行先后顺序限制，可以先执行S801再执行S802，也可以先执行S802再执行S801，或者可以同时执行S801与S802，不做限定。
S803：所述终端设备发送所述上行控制信道与所述上行数据信道中优先级高的信道上承载的信息。
其中，所述优先级可以是指发送信道上承载的信息的优先级。换言之，所述终端设备可以根据信道的优先级静默优先级低的信道，包括在重叠的时间单元上停止发送被静默的信道上承载的信息，或者完全停止发送被静默的信道上承载的信息。
以下将以所述上行控制信道为PUCCH，且所述上行数据信道为PUSCH为例，列举几种确定所述上行控制信道与所述上行数据信道的优先级顺序的方式(见如下方式1至方式5)。可以理解，下列几种方式仅为举例，本申请实施例对所述优先级顺序的确定方式不做任何限定。
方式1：所述优先级顺序是预设且固定的。例如预设PUCCH的优先级高于PUSCH的优先级；或预设PUSCH的优先级高于PUCCH的优先级。
方式2：所述优先级顺序是高层配置的。例如通过高层信令指示PUCCH的优先级高于PUSCH的优先级；或者指示PUSCH的优先级高于PUCCH的优先级。
方式3：所述优先级顺序是根据信道上承载的信息的业务类型确定的。
在一种实施方式中，承载高优先级业务的信息的信道的优先级高。在一个示例中，紧急业务例如URLLC业务的优先级高于非紧急业务例如增强移动宽带(enhanced mobile broadband，eMBB)业务的优先级。可选地，当PUSCH承载URLLC业务数据时，PUSCH的优先级高于PUCCH的优先级；当PUSCH承载eMBB业务数据时，PUCCH的优先级高于PUSCH的优先级。可选地，当PUCCH承载URLLC业务对应的A-CSI时，PUCCH的优先级高于PUSCH的优先级；当PUCCH承载eMBB业务对应的A-CSI时，如果PUSCH承载URLLC业务数据，则PUSCH的优先级高于PUCCH的优先级，如果PUSCH承载eMBB业务数据，则PUCCH的优先级高于PUSCH的优先级。
其中，PUSCH上承载的业务类型可以通过DCI指示或者半静态配置等多种方式确定，不做限定。例如，对于动态的PUSCH可以根据DCI指示确定该PUSCH上的业务类型，具体地，可以根据调度该PUSCH的DCI中的 指示信息确定该PUSCH上承载的是哪种具体业务，其中，所述指示信息可以是DCI中的无线网络临时标识(radio network temporary identifier，RNTI)或DCI格式(format)信息，也可以是专门设置的指示信息，不做限定。又例如，对于动态的PUSCH或者配置的PUSCH均可以采用半静态配置的方式确定该PUSCH上的业务类型，具体地，可以根据PUSCH关联的调制和编码方案表格(modulation and coding scheme table，MCS-table)或者根据PUSCH关联的SLIV或K1确定该PUSCH上承载的是哪种具体业务。所述具体业务可以是URLLC业务或是eMBB业务。
类似地，PUCCH上承载的A-CSI对应的业务类型也可以通过DCI指示或者半静态配置等多种方式确定，不做限定。例如，可以根据触发A-CSI的DCI中的指示信息确定该A-CSI对应的是哪种具体业务。其中，所述指示信息可以是DCI中的RNTI或DCI format信息，也可以是专门设置的指示信息，不做限定。又例如，可以根据该A-CSI关联的信道质量指示表格(channel quality indictor table，CQI table)确定该A-CSI对应的是哪种具体业务。所述具体业务可以是URLLC业务或是eMBB业务。
方式4：所述优先级顺序是按照信道的特征确定的。
其中，所述信道的特征包括PUSCH是配置的还是动态的，或者PUSCH与PUCCH调度/触发的先后顺序，或者PUCCH的起始符号与PUSCH的起始符号的先后顺序。
在一个实现方式中，当PUSCH为配置的PUSCH，则PUCCH的优先级高于PUSCH的优先级。
在一个实现方式中，当PUSCH为动态的PUSCH，则后调度/触发的信道的优先级高。例如，如果触发A-CSI的DCI在调度PUSCH的DCI之后被接收，则承载A-CSI的PUCCH的优先级高于PUSCH的优先级；如果触发A-CSI的DCI在调度PUSCH的DCI之前被接收，则PUSCH的优先级高于承载A-CSI的PUCCH的优先级。如果两种DCI同时被接收，则终端设备可以直接使用PUSCH承载A-CSI，或者设置承载A-CSI的PUCCH的优先级高，或者由高层配置优先发送哪个信道，不做限定。其中，触发A-CSI的DCI在调度PUSCH的DCI之后可以是指PUCCH对应的PDCCH发送时刻晚于PUSCH对应的PDCCH发送时刻；触发A-CSI的DCI在调度PUSCH的DCI之前可以是指PUCCH对应的PDCCH发送时刻早于PUSCH对应的PDCCH发送时刻。另一种可能方式是，终端设备不期望在相同时刻接收A-CSI的调度DCI和PUSCH的调度DCI。
以上PDCCH发送时刻可以是PDCCH的第一个时间单元或者最后一个时间单元，例如可以是PDCCU的第一个符号或者最后一个符号。
在一个实现方式中，PUCCH与PUSCH中起始符号在前的信道优先级高，或者起始符号在后的优先级高。
在上述实施方式中，当上行数据信道与承载A-CSI的上行控制信道在时 域重叠时，终端设备发送优先级高的信道上承载的信息，静默优先级低的信道，使得上行数据接收能够正确接收，尤其是在终端设备未能成功接收指示触发A-CSI的DCI的场景下，能够提升数据接收的准确性。
除了根据优先级静默上述时域重叠的上行控制信道或者上行数据信道中的一个信道来避免网络设备接收错误，在本申请的另一个实施方式中，终端设备还可以从不同的DCI中分别获取指示所述终端设备在上述时域重叠的上行控制信道以及上行数据信道上发送相同A-CSI报告的指示信息，其中，所述A-CSI报告可以是指由高层配置的在上行控制信道上承载的A-CSI。
具体地，所述方法可以包括：所述终端设备在接收用于指示终端设备在上行控制信道上发送A-CSI的DCI(如上述第一DCI)之后或同时(即所述第一DCI不晚于所述第三DCI被接收)，还从网络设备接收一个或多个第三DCI，所述第三DCI用于调度所述终端设备在上行数据信道上发送上行数据，且第三DCI中包括指示信息，所述指示信息用于指示终端设备在所述上行数据信道上发送所述A-CSI。相应地，所述终端设备可以根据所述指示信息在所述上行数据信道上发送所述上行数据以及所述A-CSI。
其中，所述A-CSI也可以称为A-CSI报告。所述第一DCI与所述第三DCI发送分别发送2次A-CSI请求(A-CSI request)，所述A-CSI请求用于触发终端设备发送A-CSI报告。
所述第一DCI还可以用于调度下行数据传输，不做赘述。
其中，所述指示信息可以是所述第三DCI中的比特域中的预设值，所述比特域可以是现有的或者专门设置的，不做限定。下面以上行控制信道为PUCCH，上行数据信道为PUSCH为例具体说明表示所述指示信息的比特域的几种设置方式。
在一种实现方式中，所述比特域是专门为触发A-CSI报告设置的。例如，可以在所述第三DCI中增加一个比特域，该新增的比特域中的预设值用于指示网络设备已经调度了一个在PUCCH上发送的A-CSI，且承载该A-CSI的PUCCH与PUSCH重叠，因此，可以需要静默对应的PUCCH，在该PUSCH上携带该A-CSI；当UE漏检触发PUCCH上承载A-CSI的DCI时，可以在PUSCH上预留对应资源位置，使得数据传输的资源位置正确。可选地，该比特域还可以用于指示所述A-CSI的比特数目；或者A-CSI对应的报告标识(report identity，report ID)，由于不同的A-CSI报告对应的信息内容大小不同，通过报告标识可以获取A-CSI的比特数目。
在一种实现方式中，可以复用所述第三DCI中现有的比特域，用该现有的比特域中的预设值用于指示网络设备已经调度了一个在PUCCH上发送的A-CSI，且承载该A-CSI的PUCCH与PUSCH重叠，因此，可以在该PUSCH上也承载该A-CSI。例如，可以复用DCI中的CSI-request比特域，设置该CSI-request比特域为预设值，该预设值用于触发与上述在PUCCH上发送的A-CSI对应相同report ID的A-CSI，具体地，该预设值可以关联上述该A-CSI 对应的A-CSI报告。所述CSI-request比特域可以是2比特或者3比特。
可选地，当PUSCH与承载A-CSI的PUCCH时域重叠，且PUSCH上承载的A-CSI与PUCCH上承载的A-CSI对应不同的report ID，则可以根据PUSCH与PUCCH的优先级，发送优先级高的信道上的信息。例如可以考虑两种信道上承载的信息的业务类型的优先级，承载紧急业务的信道的优先级高，比如所述PUCCH上承载的是URLLC业务对应的A-CSI，且指示A-CSI的DCI在调度PUSCH的DCI之后被接收，则可以优先发送该A-CSI。更多确定优先级的具体方式可以参照前文相关描述，不做赘述。
采用该实施方式，所述终端设备可以分别接收多个(两个或两个以上)A-CSI请求，所述多个A-CSI请求用于分别触发所述终端设备在一个时间单元内的重叠的上行控制信道和上行数据信道上发送相同的A-CSI报告，从而提升终端设备发送A-CSI的成功率，避免上行数据接收错误。
在另一个可能的实现方式中，当第一DCI不晚于所述第三DCI被接收，使用上述方法，在第三DCI中包括指示信息，所述指示信息用于指示终端设备在所述上行数据信道上发送第一DCI触发的A-CSI；当第一DCI晚于所述第三DCI，可以优先发送所述A-CSI，静默上行数据信道。
在另一个可能的实施方式中，终端设备可以对接收到的指示A-CSI与上行数据信道重叠发送的DCI不做处理，或者说终端设备不期望接收到由DCI触发的与上行数据信道重叠发送的A-CSI。另一个实现方式中，网络设备可以不调度一个在上行控制信道上发送的A-CSI与另一个上行数据信道在时域上重叠。其中，所述上行数据信道可以是调度的或者配置的，不做限定。因而，在该实施方式中，终端设备可以不发送与上行数据信道时域重叠的承载A-CSI的上行控制信道，换言之，发送A-CSI所用的上行控制信道与上行数据信道不重叠，因而，可以避免上行数据接收错误。
