Description

通信方法、设备及存储介质 技术领域
本申请实施例涉及通信技术，尤其涉及一种通信方法、设备及存储介质。
背景技术
已有通信系统中，引入了一种新的混合自动重传请求应答(Hybrid Automatic Repeat-reQuest-Acknowledgement，简称HARQ-ACK)码本的反馈方式：单次混合自动重传请求one-shot HARQ-ACK反馈。One-shot HARQ-ACK反馈用于反馈一个物理上行控制信道(Physical Uplink Control Channel，简称PUCCH)组中的配置载波上的所有HARQ进程的HARQ-ACK信息。
由网络侧设备为终端设备配置one-shot HARQ-ACK反馈，并通过下行控制信息(Downlink Control Information，简称DCI)指示终端设备是否进行one-shot HARQ-ACK反馈。如果终端设备被配置了one-shot HARQ-ACK反馈，那么对应DCI中可以包括one-shot HARQ-ACK反馈请求信息域。终端设备根据接收到DCI中的one-shot HARQ-ACK反馈请求信息域的指示确定是否进行one-shot HARQ-ACK反馈。其中，该DCI可以是下行授权信息。
当终端设备被触发one-shot HARQ-ACK反馈时，终端设备如何有效地进行对应的HARQ-ACK码本反馈，是需要考虑的问题。

本申请实施例的说明书、权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
本申请提供一种信息传输方法，该方法可以应用于各种通信系统，例如：全球移动通讯(global system of mobile communication，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(wideband code division multiple access，WCDMA)系统、通用分组无线业务(general packet radio service，GPRS)、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)系统、先进的长期演进(advanced long term evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、非授权频段上的NR(NR-based access to unlicensed spectrum，NR-U)系统、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、无线局域网(wireless local area networks，WLAN)、无线保真(wireless fidelity，WiFi)、下一代通信系统或其他通信系统等。

图1为本申请适用的通信系统的一种示意图，如图1所示通信系统中，以该通信系统100包 括一个网络设备110和两个终端设备120为例进行说明，可以理解，该通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。
网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。
可选地，该网络设备110可以是GSM系统或CDMA系统中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。

本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。为方便描述，本申请所有实施例中，上述为终端设备提供无线通信功能的装置统称为网络设备。
在本申请实施例中，终端设备120可以是任意的终端，比如，终端设备120可以是机器类通信的用户设备。该终端设备120也可称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal)、终端(terminal)等。
该终端设备120可以经RAN与一个或多个核心网进行通信，因此，该终端设备120还可以称为无线终端，无线终端可以是指向用户提供语音和/或数据连通性的设备，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其它处理设备。
例如，终端设备120可以为蜂窝电话、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、个人数字处理(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、车载设备或可穿戴设备，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(selfdriving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。本申请实施例中不做具体限定。
又如，终端设备120包括但不限于经由有线线路连接，如经由公共交换电话网络(Public Switched Telephone Networks，PSTN)、数字用户线路(Digital Subscriber Line，DSL)、数字电缆、直接电缆连接；和/或另一数据连接/网络；和/或经由无线接口，如，针对蜂窝网络、无线局域网(Wireless Local Area Network，WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器；和/或另一终端设备的被设置成接收/发送通信信号的装置；和/或物联网(Internet of Things，IoT)设备。被设置成通过无线接口通信的终端设备可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例包括但不限于卫星或蜂窝电话；可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(Personal Communications System，PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(Global Positioning System，GPS)接收器的PDA；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。
可选的，网络设备110和终端设备120可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上；还可以部署在空中的飞机、气球和人造卫星上。本申请的实施例对网络设备110和终端设备120的应用场景不做限定。
可选的，网络设备110和终端设备120之间以及两个终端设备120之间可以通过授权频谱(licensed spectrum)进行通信，也可以通过非授权频谱(unlicensed spectrum)进行通信，也可以同时通过授权频谱和非授权频谱进行通信。网络设备110和终端设备120之间以及终端设备和终端设备之间可以通过7吉兆赫(gigahertz，GHz)以下的频谱进行通信，也可以通过7GHz以 上的频谱进行通信，还可以同时使用7GHz以下的频谱和7GHz以上的频谱进行通信。本申请的实施例对网络设备110和终端设备120之间所使用的频谱资源不做限定。
非授权频谱是国家和地区划分的可用于无线电设备通信的频谱，该频谱通常被认为是共享频谱，即不同通信系统中的通信设备只要满足国家或地区在该频谱上设置的法规要求，就可以使用该频谱，不需要向政府申请专有的频谱授权。
为了让使用非授权频谱进行无线通信的各个通信系统在该频谱上能够友好共存，一些国家或地区规定了使用非授权频谱必须满足的法规要求。例如，电子设备(或者说，通信设备)遵循先听后说(Listen Before Talk，LBT)原则，即电子设备在非授权频谱的信道上进行信号发送前，需要先进行信道侦听，或者说，进行空闲信道检测(Clear Channel Assessment，CCA)，只有当信道侦听结果为信道空闲时，电子设备才能进行信号发送；如果电子设备在非授权频谱的信道上的信道侦听结果为信道忙，则电子设备不能进行信号发送。为了保证公平性，在一次传输中，电子设备使用非授权频谱的信道进行信号传输的时长不能超过最大信道占用时间(Maximum Channel Occupancy Time，MCOT)。
可选地，终端设备120之间可以进行终端直连(Device to Device，D2D)通信。在本申请中，终端直连通信传输的信号或信道可以称为侧行信号或侧行信道(sidelink)，用于传输侧行信号或侧行信道的传输机会可以称为侧行传输机会。
可选地，该通信系统100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例对此不作限定。
应理解，本申请实施例中网络/系统中具有通信功能的设备可称为通信设备。以图1示出的通信系统100为例，通信设备可包括具有通信功能的网络设备110和终端设备120，网络设备110和终端设备120可以为上文所述的具体设备，此处不再赘述；通信设备还可包括通信系统100中的其他设备，例如网络控制器、移动管理实体等其他网络实体，本申请实施例中对此不做限定。
本申请实施例描述的系统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。
以NR系统为例，NR系统中的上行传输包括PUCCH传输和物理上行共享信道(Physical Uplink Control CHannel，PUSCH)传输。PUSCH可用于传输数据，以及HARQ-ACK信息、预编码矩阵指示(Precoding Matrix Indicator，PMI)、信道质量指示(Channel Quality indicator，CQI)以及秩指示(Rank Indication，简称RI)等上行控制信息(Uplink Control Information，UCI)。PUCCH只能用于传输UCI，不能用于传输数据。
现有技术中，NR系统中的PUSCH传输是根据PUSCH准备时间(也称为N2处理时间或者N2)来确定的。N2处理时间与终端设备的处理能力有关，不同处理能力的终端设备的N2处理时间不同。
示例性的，终端设备的处理能力包括：处理能力1和处理能力2，处理能力1和处理能力2分别对应不同的N2处理时间，或者说，终端设备的处理能力1和处理能力2对应的N2(即PUSCH准备时间)的取值不同。N2的取值可以为时长值，还可以为符号数，还可以其他用于表示时间的量，本申请实施例不对此限制。
表1和表2分别示出了终端设备的不同处理能力下的N2的取值，且以N2的取值为符号数为例。

表2：终端处理能力2对应的PUSCH准备时间N2

表1和表2中μ对应(μ DL，μ UL)中产生一个较大T proc,2的子载波间隔配置，μ DL为调度PUSCH 的PDCCH的子载波间隔配置，μ UL为上行数据发送的子载波间隔配置。
如果终端设备接收到网络设备发送的DCI为上行授权信息，该上行授权信息用于调度终端设备发送携带目标传输块和解调参考信号(DeModulation Reference Signal，DMRS)的目标PUSCH，则终端设备可以根据该上行授权信息(例如根据该上行授权信息中的起始符号和长度SLIV指示)确定目标PUSCH。如果目标PUSCH的第一个上行符号在考虑定时提前影响后的起始位置不早于符号L2，终端设备传输该目标传输块；如果目标PUSCH的第一个上行符号在考虑定时提前影响后的起始位置早于符号L2，终端设备忽略该上行授权信息，不发送该目标PUSCH。
其中，符号L2定义为：携带该上行授权信息的PDCCH的最后一个符号的结束位置后的下一个上行符号。其中，该下一个上行符号的循环前缀(CyclicPrefix，CP)的起始位置晚于T proc,2，T proc,2满足公式(1)：
T proc,2＝max((N 2+d 2,1)(2048+144)·κ2 -μ·T C,d 2,2)     (1)
公式(1)中，μ对应(μ DL，μ UL)中产生一个较大T proc,2的子载波间隔配置，μ DL为调度PUSCH的PDCCH的子载波间隔配置，μ UL为上行数据发送的子载波间隔配置。N2为PUSCH准备时间，N2的取值见表1或表2。如果该PUSCH中的第一个符号仅用于传输DMRS，那么d 2,1＝0，否则d 2,1＝1。如果PDCCH调度的DCI触发了带宽部分(bandwidth part，BWP)切换，那么d 2,2等于BWP的切换时间，否则d 2,2＝0。T C＝1/(Δf max·N f)，Δf max＝480·10 3Hz(赫兹)，N f＝4096，κ＝64。
现有技术中，NR系统中的PUCCH传输是根据PDSCH译码时间(也称为N1处理时间或者N1)来确定的。N1处理时间与终端设备的处理能力有关，不同处理能力的终端设备的N1处理时间不同。
示例性的，终端设备的处理能力包括：处理能力1和处理能力2，处理能力1和处理能力2分别对应不同的N1处理时间，或者说，终端设备的处理能力1和处理能力2对应的N1的取值不同。表3和表4分别示出了终端设备的不同处理能力下的N1的取值。
表3：终端设备的处理能力1对应的PDSCH译码时间N1

表4：终端设备的处理能力2对应的PDSCH译码时间N1
Figure PCTCN2020074891-appb-000002
表3和表4中μ对应(μ PDCCH，μ PDSCH，μ UL)中产生一个较大T proc,1的子载波间隔配置，μ PDCCH对应调度该PDSCH的PDCCH的子载波间隔配置，μ PDSCH对应该被调度的PDSCH的子载波间隔配 置，μ UL对应传输该HARQ-ACK的上行信道的子载波间隔配置。
如果终端设备接收到网络设备发送的DCI为下行授权信息，该下行授权信息用于调度终端设备接收携带目标传输块的PDSCH，则终端设备可以根据DCI中包括的HARQ-ACK定时信息K1和PUCCH资源指示信息确定该被调度PDSCH对应的HARQ-ACK信息通过目标PUCCH传输。如果该目标PUCCH的第一个上行符号在考虑定时提前影响后的起始位置不早于符号L1，终端设备通过目标PUCCH向网络设备发送该被调度PDSCH的有效HARQ-ACK信息；如果该目标PUCCH的第一个上行符号在考虑定时提前影响后的起始位置早于符号L1，终端设备可以不向网络设备发送该被调度PDSCH的有效HARQ-ACK信息。
其中，符号L1定义为：携带该目标传输块的PDSCH的最后一个符号的结束位置后的下一个上行符号，其中，该下一个上行符号的CP的起始位置晚于T proc,1，T proc,1满足公式(2)：
T proc,1＝(N 1+d 1,1)(2048+144)·κ2 -μ·T C    (2)
公式(2)中，μ对应(μ PDCCH，μ PDSCH，μ UL)中产生一个较大T proc,1的子载波间隔配置，μ PDCCH对应调度该PDSCH的PDCCH的子载波间隔配置，μ PDSCH对应该被调度的PDSCH的子载波间隔配置，μ UL对应传输该HARQ-ACK的上行信道的子载波间隔配置。N1为PDSCH译码时间，N1的取值参照表3或表4。d 1,1的取值和PDSCH的映射类型以及PDSCH的符号长度有关，T C＝1/(Δf max·N f)，Δf max＝480·10 3赫兹，N f＝4096，κ＝64。
NR系统中，携带HARQ-ACK信息的PUCCH传输是根据PDSCH译码时间来确定的。
在NR-U系统中，引入了one-shotHARQ-ACK反馈，one-shotHARQ-ACK反馈用于触发反馈Type-3HARQ-ACK码本。携带one-shotHARQ-ACK反馈请求信息的DCI可以调度PDSCH传输，也可以不调度PDSCH传输。当DCI调度PDSCH时，终端设备可以根据被调度的PDSCH的处理时间(或者说PDSCH的译码时间)来进行用于one-shotHARQ-ACK反馈的上行信道例如PUCCH的传输。但是，当DCI不调度PDSCH时，终端设备无法根据PDSCH处理时间进行用于one-shotHARQ-ACK反馈的上行信道的传输，从而可能导致one-shotHARQ-ACK反馈失败。如何确定one-shotHARQ-ACK反馈的上行信道是否满足处理时间，是一个待解决的问题。
图2为本申请实施例一提供的通信方法的流程图，如图2所示，本实施例提供的方法包括以下内容中的至少部分内容：
本申请实施例提供一种信息传输方法，该方法适用于DCI调度PDSCH或DCI不调度PDSCH的情况下，通过在DCI中携带指示终端设备进行目标上行信道或信号传输的请求信息，指示终端设备在目标上行资源上进行上行传输。终端设备在满足时延要求后通过目标上行资源向网络设备发送目标上行信道或信号；或者，在不满足时延要求时，终端设备不发送目标上行信道或信号，或者，终端设备向网络设备发送目标上行信道或信号，目标上行信道中包括至少部分无效的信息。该DCI可以调度PDSCH，也可以不调度PDSCH，从而可以保证在DCI调度PDSCH或不调度PDSCH的情况下，终端设备均能够确定目标上行信道或信号的处理时延，保证目标上行信道或信号的信息准确传输。
可选地，目标上行信道或信号包括以下至少一种：PUSCH，PUCCH，物理随机接入信道(Physical random access channel，PRACH)，探测参考信号(Sounding reference signal，SRS)，相位跟踪参考信号(Phase-tracking reference signal，PT-RS)。
可选地，DCI包括下行授权信息或上行授权信息。
可选地，本申请实施例中的方法也可以应用于终端设备和终端设备之间的通信，例如用于确定目标侧行信道或信号是否满足处理时域。本申请对此不再赘述。
以下，以one-shot HARQ-ACK反馈过程、调度的PUSCH和调度的PUCCH传输为例，对本申请实施例的方法进行说明。携带one-shot HARQ-ACK反馈请求信息的DCI可以调度PDSCH传输，也可以不调度PDSCH传输。

图5为PUCCH的处理时延根据N1确定时的上行调度的一种时序示意图，如图5所示，当PDCCH携带调度PDSCH的下行授权信息时，终端设备在接收到PDCCH后，根据传输PDSCH的最后一个符号和T1时长确定第二符号(或者说符号L1)，其中，第二符号是从PDSCH的最后一个符号的结束位置开始的T1时长后的下一个上行符号，T1是根据N1确定的。
在一个示例中，T1的结束位置位于上行符号n的中间位置，因此，从PDSCH的最后一个符号的结束位置开始的T1时长后的下一个上行符号为符号n+1，或者说，第二符号为上行符号n+1。当目标PUCCH的第一个上行符号考虑定时提前后的起始位置不早于第二符号，则确定目标PUCCH满足时延要求，或者，当目标PUCCH的第一个上行符号考虑定时提前后的起始位置早于第二符号，则确定目标PUCCH不满足时延要求。如图所示，当目标PUCCH在符号n+2，n+3上传输时，可以认为该目标PUCCH满足时延要求。
在另一个示例中，T1的结束位置位于上行符号n的结束位置，因此，从PDSCH的最后一个符号的结束位置开始的T1时长后的下一个上行符号为符号n+2，或者说，第二符号为上行符号 n+2。当目标PUCCH的第一个上行符号考虑定时提前后的起始位置不早于第二符号，则确定目标PUCCH满足时延要求，或者，当目标PUCCH的第一个上行符号考虑定时提前后的起始位置早于第二符号，则确定目标PUCCH不满足时延要求。如图所示，当目标PUCCH被调度在符号n+3，n+4上传输时，可以认为该目标PUCCH满足时延要求。
在一些示例中，T1的结束位置位于上行符号n的结束位置时，终端设备可以将上行符号n+1确定为第二符号，本申请也不排除该类情况。
图6为PUCCH的处理时延根据N1确定时的上行调度的一种时序示意图，如图6所示，当PDCCH携带调度PDSCH的下行授权信息时，终端设备在接收到PDCCH后，根据传输PDSCH的最后一个符号和T1时长确定第二符号(或者说符号L1)，其中，第二符号是从PDSCH的最后一个符号的结束位置开始的T1时长后的下一个上行符号，T1是根据N1确定的。
如图6所示，终端设备确定第二符号为上行符号n+1。下行授权信息指示的目标PUCCH中的第一个符号包括CPE。当目标PUCCH的第一个上行符号考虑定时提前后的CPE的起始位置不早于第二符号例如第二符号的起始位置，则确定目标PUCCH满足时延要求，或者，当目标PUCCH的第一个上行符号考虑定时提前后的CPE的起始位置早于第二符号的起始位置，则确定目标PUCCH不满足时延要求。如图所示，被指示的目标PUCCH的起始位置位于符号n+1中，用于PUCCH传输的符号包括符号n+2，n+3，其中，符号n+1中传输符号n+2的延长循环前缀，在该示例下，可以认为该目标PUCCH满足时延要求。
