Description

通信方法和通信装置
本申请要求于2019年08月02日提交中国专利局、申请号为201910709758.5、申请名称为“通信方法和通信装置”以及2019年09月30日提交中国专利局、申请号为201910941447.1、申请名称为“通信方法和通信装置”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
本申请涉及通信领域，尤其涉及一种通信方法和通信装置。
背景技术
为了应对未来爆炸性的移动数据流量增长、海量移动通信的设备连接、不断涌现的各类新业务和应用场景，第五代(the fifth generation，5G)移动通信系统应运而生。5G移动通信系统需要支持增强型移动宽带(enhanced mobile broadband，eMBB)业务、高可靠低时延通信(ultra reliable and low latency communications，URLLC)业务以及海量机器类通信(massive machine type communications，mMTC)业务。
不同业务对移动通信系统的需求不同。例如，典型的eMBB业务有：超高清视频、增强现实(augmented reality，AR)、虚拟现实(virtual reality，VR)等，这些业务的主要特点是传输数据量大、传输速率很高。典型的URLLC业务有：工业制造或生产流程中的无线控制、无人驾驶汽车和无人驾驶飞机的运动控制以及远程修理、远程手术等触觉交互类应用，这些业务的主要特点是超高可靠性、低延时，传输数据量较少以及具有突发性。在一些紧急情况下，URLLC业务可能会抢占eMBB业务的传输资源。
为了满足URLLC业务的传输时延需求，降低URLLC场景的反馈时延，可以将一个时隙划分为多个子时隙，同一个子时隙可包括多个物理下行共享信道(physical downlink shared channel，PDSCH)，然后在每个子时隙上选择一个物理上行控制信道(physical uplink control channel，PUCCH)资源反馈这些PDSCH承载的下行数据的混合式自动重送请求(hybrid automatic repeat request acknowledgement，HARQ-ACK)消息，其中，HARQ-ACK消息包括肯定应答消息(acknowledgement，ACK)或否定应答消息(negative acknowledgement，NACK)。
现有技术中，网络设备为终端设备的子时隙统一配置PUCCH资源集合(PUCCH resource set)，不同子时隙的PUCCH资源集合相同。不同的子时隙中真正可用的用于前述反馈的PUCCH资源不同，由于双分时工(time division duplexing，TDD)和时隙边界限制等原因，某些子时隙中没有真正可用的PUCCH资源。从而影响URLLC业务的反馈时延，降低数据传输的可靠性。
发明内容
本申请提供了一种通信方法和通信装置，能够减小URLLC业务的反馈时延，提高数据传输的可靠性。
第一方面，提供了一种通信方法，包括：接收配置信息，该配置信息用于配置第一物理上行控制信道PUCCH资源集合，该第一PUCCH资源集合中的PUCCH资源以子时隙级别subslot-level配置；从该第一PUCCH资源集合中确定子时隙的第二PUCCH资源集合，该第二PUCCH资源集合包括该第一PUCCH资源集合中在该子时隙中可用的PUCCH资源；在该第二PUCCH资源集合中的该可用的PUCCH资源上发送对下行数据的反馈信息。
上述技术方案中，网络设备先为终端设备对某一时隙配置第一PUCCH资源集合，每个子时隙的第一PUCCH资源集合相同，终端设备再为每一个子时隙选择出该子时隙的第二PUCCH资源集合，其中，该第二PUCCH资源集合包括第一PUCCH资源集合在该子时隙中可用的PUCCH资源，从而使得该子时隙中有可用的PUCCH资源，减小了这个子时隙对应URLLC业务反馈时延，提高数据传输的可靠性。另外，由于有的子时隙中可用的PUCCH资源数量小于配置的第一PUCCH资源集合中的PUCCH资源数量，因此先统一配置第一PUCCH资源集合，然后再从第一PUCCH资源集合中确定每一个子时隙的第二PUCCH资源集合，从而减少了冗余的信令。例如，统一配置了2 N个第一PUCCH资源集合，需要用N比特去指示其中的一个PUCCH资源，但由于每一个子时隙中的可用资源数量小于2 N个，用N比特表示会产生很多冗余图案，通过为每一个子时隙确定该子时隙的可用资源集合(即第二PUCCH资源集合)，可以用小于N的比特数去指示该子时隙的第二PUCCH资源集合中的每一个PUCCH资源，从而减少下行信令中的冗余开销。
其中，第一PUCCH资源集合中的每一个PUCCH资源以子时隙级别配置可以理解为每个PUCCH资源按照每个子时隙分别配置，例如第一PUCCH资源集合包括PUCCH资源1到资源6，则PUCCH资源1，2配置给子时隙1，PUCCH资源3，4配置给子时隙2，PUCCH资源5，6配置给子时隙3。第一PUCCH资源集合中的每一个PUCCH资源的起始符号以子时隙边界做参考，例如，每一个PUCCH资源的起始符号为该子时隙的第一个符号到该子时隙长度(subslot length)个符号中的任意一个符号。
在一些可能的实现方式中，该配置信息可以由网络设备通过高层消息发送至终端设备，该高层消息可以是无线资源控制(radio resource control，RRC)消息或者介质接入控制(media access control，MAC)层消息。网络设备可以通过下行信道发送上述高层消息，该下行信道可以是物理下行共享信道(physical downlink shared channel，PDSCH)，也可以是其它类型的下行信道，本申请对网络设备如何发送高层消息不作限定。
网络设备向终端设备统一配置第一PUCCH资源集合，其中，该第一PUCCH资源集合的配置是基于subslot级别的，即该第一PUCCH资源集合中的每个PUCCH资源的起始符号(starting symbol index)是以subslot边界作为参考的，长度为1-slot长度(length of slot)个符号不等。每个PUCCH资源的参数包括以下至少一种：PUCCH资源的起始符号(strating symbol)、PUCCH资源长度、频域位置以及正交掩码(orthogonal cover code，OCC)的索引信息。
结合第一方面，在第一方面的某些可能的实现方式中，该可用的PUCCH资源满足以下任一种条件：该可用的PUCCH资源所在的符号为上行符号或灵活符号；该可用的 PUCCH资源未超出该子时隙所在的时隙边界；该可用的PUCCH的持续时间大于或等于第一阈值，其中，该第一阈值与调度该下行数据的物理下行共享信道PDCCH的聚合等级对应；该可用的PUCCH的起始符号在第一时间之后，该第一时间与终端设备物理层处理承载该下行数据的PDSCH所需的时间相关。
终端设备根据上述条件中的任意一种条件或几种条件的结合在第一PUCCH资源集合中确定该时隙中每个子时隙中可用的PUCCH资源，组成该子时隙的第二PUCCH资源集合，其中，该第二PUCCH资源集合包括从第一PUCCH资源集合中确定的该子时隙可用的PUCCH资源。
应理解，确定出的每个子时隙的第二PUCCH资源集合可能相同，也可能不同，本申请实施例对此并不作限定。
结合第一方面，在第一方面的某些可能的实现方式中，该从该第一PUCCH资源集合中确定子时隙的第二PUCCH资源集合，包括：获取第一参数，该第一参数为该第二PUCCH资源集合中该可用的PUCCH资源最大个数；根据该第一参数从该第一PUCCH资源集合中确定该第二PUCCH资源集合。
终端设备从第一PUCCH资源集合中确定在该子时隙中可用的PUCCH资源，并根据该第一参数从该确定的可用的PUCCH资源中确定相应数量的可用的PUCCH资源组成该子时隙的第二PUCCH资源集合。
应理解，根据第一参数的不同，确定的该子时隙的第二PUCCH资源集合中的可用的PUCCH资源可能包括所有从第一PUCCH资源集合中确定的该子时隙可用的PUCCH资源，也可能包括部分从第一PUCCH资源集合中确定的该子时隙可用的PUCCH资源，本申请实施例对此不作限定。
结合第一方面，在第一方面的某些可能的实现方式中，该第一参数由协议预配置或网络设备配置。
第二方面，提供了一种通信方法，包括：接收配置信息，该配置信息用于配置第一物理上行控制信道PUCCH资源集合；在该第一PUCCH资源集合中的PUCCH资源上发送对下行数据的反馈信息，该PUCCH资源的起始符号在时隙中的至少一个子时隙中，该至少一个子时隙中的每一个子时隙包括至少一个上行符号或灵活符号，其中，该至少一个上行符号或灵活符号中的第一个上行符号或灵活符号在该子时隙中的位置与该子时隙的起始符号的位置相差M个符号，M为非负整数，且M小于或等于该子时隙的长度。
上述技术方案中，终端设备将时隙划分为至少一个子时隙，子时隙包括至少一个上行符号或灵活符号，其中，该至少一个上行符号或灵活符号中的第一个上行符号或灵活符号在该子时隙中的位置与该子时隙的起始符号的位置相差M个符号，M为非负整数，且M小于或等于该子时隙的长度。该时隙划分后的每一个子时隙中的第一个上行符号或灵活符号的位置相同，网络设备在预配置第一PUCCH资源集合时，充分考虑这一点，避免配置的第一PUCCH资源集合中大量PUCCH资源不可用，在减小URLLC业务的反馈时延的同时降低了网络设备配置第一PUCCH资源集合的复杂度。
应说明，网络设备配置的第一PUCCH资源集合中的每一个PUCCH资源可以以子时隙级别(subslot-level)配置，也可以以时隙级别(slot-level)配置，本申请实施例对此不作限定。
其中，第一PUCCH资源集合中的每一个PUCCH资源以子时隙级别配置可以理解为 第一PUCCH资源集合中的每一个PUCCH资源的起始符号以子时隙边界做参考，即每一个PUCCH资源的起始符号为该子时隙的第一个符号到该子时隙长度(subslot length)个符号中的任意一个符号。第一PUCCH资源集合中的每一个PUCCH资源以时隙级别配置可以理解为第一PUCCH资源集合中的每一个PUCCH资源的起始符号以时隙边界做参考，即每一个PUCCH资源的起始符号为该时隙的第一个符号到该时隙长度(slot length)个符号中的任意一个符号。
结合第二方面，在第二方面的某些可能的实现方式中，该方法还包括：获取该至少一个子时隙的长度信息；根据该至少一个子时隙的长度信息以及上下行符号配置确定该至少一个子时隙位置。
其中，上下行符号配置包括上行符号、下行符号和灵活符号的配置。
结合第二方面，在第二方面的某些可能的实现方式中，根据该至少一个子时隙的长度信息以及上下行符号配置确定该至少一个子时隙位置，包括：根据该至少一个子时隙的长度信息划分该时隙；从该时隙的第一个符号开始直到找到第一个上行符号或灵活符号，从该第一个上行符号或灵活符号开始连续的N个符号作为该至少一个子时隙，其中，该至少一个子时隙中包括下行符号和/或上行符号或灵活符号，其中N为小于或等于该至少一个子时隙的长度的正整数。
或者，终端设备从该时隙中的第一符号开始，直到第一个可用符号，并从该符号的前一个符号开始，将连续的N个符号作为该子时隙，其中，N为小于或等于至少一个子时隙的长度的正整数。确定该时隙中的第一个子时隙后，继续查找，从下一个可用符号的前一个符号开始，将连续的N个长度的符号作为第二个子时隙，依次类推，直至该时隙的最后一个符号。划分完后，该时隙中的每一个子时隙的第二个符号为第一个上行符号或灵活符号，即每个子时隙中第一个上行符号或灵活符号在该子时隙中的位置与该子时隙的起始符号的位置相差1个符号。
应理解，由于时隙中上下行符号的配置，使得每个子时隙中确定的N个符号可能包括可用符号或者不可用符号。根据M取值的不同，划分完后的子时隙中的第一个上行符号或灵活符号在子时隙中的位置可能不同，例如，第一个上行符号或灵活符号为子时隙的起始符号，或者为子时隙的第二个符号、第三个符号……但该时隙中的每个子时隙的第一个上行符号或灵活符号在子时隙中的位置相同即可，本申请对具体的划分方式并不作具体限定。
结合第二方面，在第二方面的某些可能的实现方式中，该至少一个子时隙的长度信息为协议预配置或网络设备配置。
第三方面，提供了一种通信方法，包括：接收配置信息，该配置信息用于配置第一物理上行控制信道PUCCH资源集合，该第一PUCCH资源集合是按照第一子时隙类型配置的；在确定对下行数据的反馈信息所在的子时隙为该第一子时隙类型的情况下，在该第一PUCCH资源集合中的PUCCH资源上发送该反馈信息。
其中，第一PUCCH资源集合可以是以子时隙类型级别配置的，即不同的子时隙类型可以对应不同的PUCCH资源集合；相同的子时隙类型可以对应一个PUCCH资源集合。
在本申请的技术方案中，可以根据不同的子时隙类型配置不同的PUCCH资源集合，通过可以能够充分考虑不同子时隙的属性，使得特征相似的子时隙，即相同子时隙类型的 子时隙对应同一PUCCH资源集合，能够避免PUCCH资源集合中出现大量的不可用资源，实现减少下行信令中的冗余开销。
结合第三方面，在第三方面的某些可能的实现方式中，该配置信息用于配置包含第一PUCCH资源集合的多个PUCCH资源集合，该多个PUCCH资源集合对应多个子时隙类型，每一个PUCCH资源集合对应一个子时隙类型；其中，该在确定对下行数据的反馈信息所在的子时隙为该第一子时隙类型的情况下，在该第一PUCCH资源集合中的PUCCH资源上发送该反馈信息，包括：确定该反馈信息所在子时隙为该多个子时隙类型中的该第一子时隙类型；从该多个PUCCH资源集合中确定该第一子时隙类型对应的该第一PUCCH资源集合，在该第一PUCCH资源集合中的PUCCH资源上发送该反馈信息。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：新无线(new radio，NR)系统的演进系统(例如非授权频谱上的NR(NR-based access to unlicensed spectrum，NR-U)系统)或其他通信系统等。
需要说明的是，在本申请的实施例中，子时隙可以是指数据传输时使用的时间调度单元，其中，时隙中可以包括一个或多个子时隙，子时隙可以是与时隙相比更短的时间单元；子时隙还可以称为子时间单元或者其它名称，本申请对此不作任何限定。
例如，在NR系统中一个时隙可以由12个或14个时域符号组成，组成子时隙的符号数可以是比12个或14个更少的时域符号，比如2个时域符号或7个时域符号或者其他数量的时域符号，本申请对此不作任何限定。
应理解，在本申请的各实施例中，“第一”、“第二”、“第三”等仅是为了指代不同的对象，并不表示对指代的对象有其它限定。
图1示出了一种适用于本申请的通信系统的示意图。
通信系统100包括网络设备110、终端设备120和终端设备130。终端设备120通过电磁波与网络设备110进行通信，终端设备130通过电磁波与网络设备110进行通信，终端设备120与终端设备130之间也可以通过电磁波进行通信。
在本申请中，终端设备120和终端设备130可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，例如，第三代合作伙伴计划(3 rd generation partnership project，3GPP)所定义的用户设备(user equipment，UE)，移动台(mobile station，MS)，软终端，家庭网关，机顶盒等等。应用于上述设备中的芯片也可以称为终端设备。
网络设备110可以是3GPP所定义的基站，例如，5G通信系统中的基站(gNB)。网络设备110也可以是非3GPP(non-3GPP)的接入网设备，例如接入网关(access gateway，AGF)。网络设备还可以是中继站、接入点、车载设备、可穿戴设备以及其它类型的设备。
终端设备120和终端设备130可以传输相同类型的数据，也可以传输不同类型的数据。当终端设备120和终端设备130传输不同类型的数据时，作为一个可选的示例，终端设备120传输eMBB业务的数据包(简称为“eMBB数据”)、终端设备130传输URLLC业务的数据包(简称为“URLLC数据”)。
URLLC业务对时延要求极高，在不考虑可靠性的情况下，传输时延要求在0.5毫秒(millisecond，ms)以内，在达到99.999％的可靠性的前提下，传输时延要求在1ms以内。
在长期演进(long term evolution，LTE)系统中，最小的时间调度单元为一个1ms时间长度的传输时间间隔(transmission time interval，TTI),例如子帧。在NR系统中，为了满足URLLC业务的反馈时延需求，无线空口的数据传输可以使用更短的时间调度单元，例如，使用子时隙(subslot)或相比LTE系统具有更大的子载波间隔的时隙(slot)作为最小的时间调度单元。其中，一个subslot包括一个或多个时域符号，这里的时域符号可以是正交频分复用(orthogonal frequency division multiplexing，OFDM)符号(symbol)。一个slot包含14个时域符号(常规循环前缀)或12个时域符号(扩展循环前缀)。对于子载波间隔为15千赫兹(kilohertz，kHz)的一个slot，其对应的时间长度为1ms；对于子载波间隔为60kHz的一个slot，对应的时间长度则缩短为0.25ms。
为了降低URLLC场景的反馈时延，可以在一个slot内发送多个针对下行数据的反馈信息。例如，HARQ-ACK消息。即，将一个slot划分为多个subslot，用于指示HARQ-ACK反馈所在的时隙的参数K1的指示粒度由slot级变为subslot级。所有指向同一个subslot的PDSCH(即PDSCH的HARQ-ACK消息在同一个subslot上反馈)构成一个组，然后在每个subslot上选择一个PUCCH资源反馈这些PDSCH的HARQ-ACK消息，从而实现在一个slot内反馈多个HARQ-ACK消息。
现有技术中，网络设备通过高层信令向终端设备配置slot中的subslot图案，不同slot中的subslot图案相同，其中，subslot图案是slot中的subslot个数、每个subslot的具体位置(包括起始OFDM符号与持续的OFDM符号个数)。网络设备为终端设备统一配置PUCCH资源集合，所有的subslot的PUCCH资源集合相同。
但由于在TDD时，不同的subslot中的可用符号的位置不同，其中，可用符号包括上行符号和灵活(flexible)符号，使得每个subslot中真正可用的PUCCH资源个数不同。当网络设备统一配置的PUCCH资源集合太小时，可能导致某些subslot中真正可用的PUCCH资源个数很少，甚至为零，从而影响URLLC业务反馈时延；当网络设备统一配置的PUCCH资源集合太大时，对于都是可用符号的subslot来说需要3比特(bit)甚至更多比特PUCCH资源指示(PUCCH resource indicator)结合更多比特的下行控制信息(downlink control  information，DCI)或者其他隐式方法，才能指示该PUCCH资源集合中的所有PUCCH资源，增加了指示信息的比特数，即增加了控制信道的信息大小。在占据同样的物理资源时，控制信道的信息越多，接收可靠性越低。而控制信道的信息是用来调度数据传输的，控制信息接收错误，影响数据传输。因此，当控制信道的信息增加时，会进一步影响URLLC业务的数据传输的可靠性。
有鉴于此，本申请实施例提供了一种通信方法200，通信方法200可以应用于图1所示的通信系统，例如，可以由终端设备120或终端设备130执行，也可以由终端设备120中的芯片或终端设备130中的芯片执行。为了简洁，下文所述的“终端设备”和“网络设备”不再附带附图标记。
如图2所示，方法200包括如下步骤。
S210，终端设备接收配置信息。
其中，该配置信息用于配置第一物理上行控制信道PUCCH资源集合，第一PUCCH资源集合中的每一个PUCCH资源以子时隙级别(subslot-level)配置。
应说明，“第一PUCCH资源集合中的每一个PUCCH资源以子时隙级别配置”可以理解为第一PUCCH资源集合中的每一个PUCCH资源的起始符号以子时隙边界做参考，即每一个PUCCH资源的起始符号为该子时隙的第一个符号到该子时隙长度(subslot length)个符号中的任意一个符号。
在一些可能的实现方式中，该配置信息可以由网络设备通过高层消息发送至终端设备，该高层消息可以是无线资源控制(radio resource control，RRC)消息或者介质接入控制(media access control，MAC)层消息。网络设备可以通过下行信道发送上述高层消息，该下行信道可以是物理下行共享信道(physical downlink shared channel，PDSCH)，也可以是其它类型的下行信道，本申请对网络设备如何发送高层消息不作限定。
网络设备向终端设备统一配置第一PUCCH资源集合，其中，该第一PUCCH资源集合的配置是基于subslot级别的，即该第一PUCCH资源集合中的每个PUCCH资源的起始符号(starting symbol index)是以subslot边界作为参考的，长度为1-slot长度(length of slot)个符号不等。每个PUCCH资源的参数包括以下至少一种：PUCCH资源的起始符号(strating symbol)、PUCCH资源长度、频域位置以及正交掩码(orthogonal cover code，OCC)的索引信息。
S220，终端设备从第一PUCCH资源集合中确定子时隙的第二PUCCH资源集合。
由于第一PUCCH资源集合是网络设备为所有时隙中的子时隙统一配置的，所有的子时隙的第一PUCCH资源集合相同，即第一PUCCH在所有子时隙中的起始位置和持续长度相同。只有当PUCCH资源包含的所有符号都是可用符号时，该PUCCH资源才是可用资源，但在TDD中，不同子时隙中的可用符号(包括上行符号和灵活符号)位置不同，则每个子时隙中的可用PUCCH资源个数可能不同，有的子时隙中可用的PUCCH资源个数很少甚至为零，影响URLLC业务的反馈时延，降低数据传输的可靠性。
为了保证每个子时隙中都有可用的PUCCH资源，终端设备可以为每个子时隙从第一PUCCH资源集合中选择第二PUCCH资源集合，其中，该第二PUCCH资源集合包括第一PUCCH资源集合中在该子时隙中可用的PUCCH资源。
从第一PUCCH资源集合中的PUCCH资源中选择该子时隙可用的PUCCH资源。其 中，该子时隙可用的PUCCH资源满足以下任意一种条件：
(a)该PUCCH资源所在的符号为非下行符号
其中，该非下行符号包括上行符号和灵活符号。该上行符号或灵活符号可以为网络设备通过高层消息配置的上行符号或灵活符号或者时隙格式指示(slot format indication，SFI)指示的上行符号或灵活符号。本申请实施例对此并不作限定。
(b)该PUCCH资源未超出该子时隙所在的时隙边界
3GPP协议中规定了PUCCH资源不可以跨时隙边界，但可以跨子时隙边界。当PUCCH资源超出该子时隙所在的时隙边界时，该PUCCH资源不可用。
(c)该PUCCH的持续时间大于或等于第一阈值，其中，该第一阈值与调度下行数据的PDCCH的聚合等级一一对应。
上行控制信道PUCCH承载着上行发送调度请求信息、下行PDSCH信道的ACK/NACK反馈信息、下行无线信道的CQI反馈等控制信息,这些信息对基站配置时频资源、调制编码方式等起着至关重要的作用。PUCCH资源集合是用来反馈PDSCH对应的反馈信息资源。聚合等级(aggregation level，AL)是用来发送承载DCI的PDCCH占据的控制资源的单位，在NR系统中，AL可以取1、2、4、8、16，AL值越大，则该PDCCH占据的控制资源越多，可靠性越高。通常在信道条件较差时，网络设备会采用较大的AL值的PDCCH发送给终端设备，此时终端设备也需要采用持续时间(duration)较长的PUCCH资源向网络设备发送对下行数据的反馈信息，以保证网络设备的接收正确率。
在一些可能的实现方式中，终端设备可以根据协议预配置的表1确定第一阈值，并选择持续时间大于或大于等于该第一阈值的PUCCH资源为该可用的PUCCH资源。
表1
聚合等级 阈值
1 1
2 2
4 3
8 5
16 7
表1示出了聚合等级与阈值的对应关系，当聚合等级越高时，阈值也随之增大。例如，当聚合等级为4时，阈值为3，当聚合等级为16时，阈值为7。在确定阈值后，终端设备可以选择PUCCH资源的持续时间大于或大于等于阈值的PUCCH资源为可用资源。
应理解，表1中的具体数值仅仅为举例说明，本申请实施例对此并不作具体限定。
(d)该PUCCH的起始符号在第一时间之后，该第一时间与所述终端设备处理承载下行数据的物理下行共享信道PDSCH所需的时间相关。
由于PUCCH资源是用来反馈该PDSCH对应的HARQ-ACK消息的资源，终端设备把PDSCH的接收(包括对导频符号的信道估计、对PDSCH上承载的数据块的解调、译码)完成后再生成HARQ-ACK消息。目前R15的协议中给出了终端设备处理PDSCH的时间要求T，也就是说，在PDSCH最后一个OFDM符号之后的T时间后反馈HARQ-ACK消息，则全部或部分位于这个时间点之前的PUCCH资源是不可用的。
终端设备确定可用的PUCCH资源后，将该可用的PUCCH资源按照PUCCH资源的 标识(identify，ID)从小到大排序构成第二PUCCH资源集合，直到达到该第二PUCCH资源集合允许的PUCCH资源最大个数或者直到第一PUCCH资源集合中的最大的资源标识ID。
可选地，协议中可以规定第一PUCCH资源集合中的PUCCH资源的最大数为M，第二PUCCH资源集合中的PUCCH资源的最大数为N，其中，M、N均为正整数，且M大于或等于N。
在网络设备配置第一PUCCH资源集合时，可以不具体限定第一PUCCH资源集合中的PUCCH资源个数，终端设备从第一资源PUCCH资源集合中确定第二PUCCH资源集合，其中，第二PUCCH资源集合中的PUCCH资源个数可能小于或等于第一PUCCH资源集合中的PUCCH资源，本申请实施例对此并不作限定。
在一些可能的实现方式中，在步骤S220之前，方法200还包括步骤S211，终端设备获取第一参数。
其中，第一参数为第二PUCCH资源集合中的PUCCH资源最大个数。终端设备在确定第二PUCCH资源集合时，可以先确定第二PUCCH资源集合中的PUCCH资源的最大个数。例如，协议预设、网络设备配置或者根据表2来确定。
表2
子时隙持续时间(单位：符号) PUCCH资源个数
2 2
4 4
7 8
… …
表2示出了子时隙持续时间与PUCCH资源个数的对应关系。如表2所示，当子时隙持续时间越长时，该子时隙中的PUCCH资源个数越多，例如，当子时隙持续时间为4个符号时，PUCCH资源个数为4个，当子时隙持续时间为7个符号时，PUCCH资源个数为8个。
应理解，表2中的数值仅仅为了示例说明，本申请对此对应关系并不作限定。
在确定该第二PUCCH资源集合中的PUCCH资源个数后，终端设备从第一PUCCH资源集合中确定相应子时隙的第二PUCCH资源集合，其中，每个子时隙第二PUCCH资源集合可能不同。
应说明，终端设备从第一PUCCH资源集合中确定在该子时隙中可用的PUCCH资源，并根据第一参数确定第二PUCCH资源集合，假设第一PUCCH资源集合中包括P个PUCCH资源，终端设备确定在该子时隙中可用的PUCCH资源为Q个，其中，P、Q均为正整数且P大于等于Q。“第二PUCCH资源集合包括第一PUCCH资源集合中在所述子时隙中可用的PUCCH资源”可能存在以下几种情况：
情况1
第一参数取值K(K为正整数)为小于确定的可用的PUCCH资源的个数Q。则终端设备将从第一PUCCH资源中确定的在该子时隙中可用的PUCCH资源按照资源标识从小到大排序，并从依次取K个PUCCH资源，组成第二PUCCH资源集合。此时，该第二PUCCH资源集合中可用的PUCCH资源个数小于终端设备从第一PUCCH资源集合中确定的在该 子时隙中可用的PUCCH资源。终端设备在第二PUCCH资源集合中这K个可用的PUCCH资源集合上发送对下行数据的反馈信息。
情况2
第一参数取值K为大于或等于确定的可用PUCCH资源的个数Q。例如，K等于Q，则终端设备将从第一PUCCH资源中确定的在该子时隙中可用的PUCCH资源按照资源标识从小到大排序，这Q个可用的PUCCH资源组成第二PUCCH资源集合。此时，该第二PUCCH资源集合中可用的PUCCH资源个数等于终端设备从第一PUCCH资源集合中确定的在该子时隙中可用的PUCCH资源。或者，K大于Q，由于终端设备从第一PUCCH资源集合中确定的在该子时隙中可用的PUCCH资源的个数为Q，小于第一参数取值K，此时第二PUCCH资源集合仍然由这Q个可用的PUCCH资源组成。终端设备在第二PUCCH资源集合中这Q个可用的PUCCH资源集合上发送对下行数据的反馈信息。
应理解，上述情况中的参数值仅仅为了便于举例说明，本申请实施例对第一参数值的具体数值不作限定。
S230，终端设备在第二PUCCH资源集合中的可用的PUCCH资源上发送对下行数据的反馈信息。
终端设备在确定所有子时隙的第二PUCCH资源集合后，在该第二PUCCH资源集合中的可用的PUCCH资源上发送对下行数据的反馈信息，其中，该对下行数据的反馈信息可以为HARQ-ACK消息。
终端设备根据DCI中固有的N比特PUCCH资源指示(PUCCH resource indicator)域指示的索引值，从该第二PUCCH资源集合中确定发送对该下行数据的反馈信息的PUCCH资源。
如果该第二PUCCH资源中的PUCCH资源个数不超过2 N个则终端设备直接根据PUCCH resource indicator域指示的索引值，从该第二PUCCH资源集合中确定PUCCH资源。
或者，如果第二PUCCH资源集合中的PUCCH资源个数超过2 N个，则终端设备根据PUCCH resource indicator域指示的索引值以及该DCI在整个控制资源集合(control resource set，CORESET)中的位置，从该第二PUCCH资源集合中确定PUCCH资源。
终端设备在确定的PUCCH资源上发送包括HARQ-ACK消息在内的UCI，相应的，网络设备在确定的PUCCH资源上接收包括HARQ-ACK消息在内的UCI。
上述技术方案中，网络设备先向子时隙配置第一PUCCH资源集合，终端设备再为每一个子时隙选择出该子时隙的第二PUCCH资源集合，其中，该第二PUCCH资源集合包括第一PUCCH资源集合在该子时隙中可用的PUCCH资源，从而使得每个子时隙中均有可用的PUCCH资源，减小了URLLC业务反馈时延，提高数据传输的可靠性，并且减少了信令开销。
图3示出了本申请实施例提供的另一种通信方法300的示意性流程图。通信方法300可以应用于图1所示的通信系统，例如，可以由终端设备120或终端设备130执行，也可以由终端设备120中的芯片或终端设备130中的芯片执行。
如图3所示，方法300包括如下步骤。
S310，终端设备接收配置信息。
其中，该配置信息用于配置第一物理上行控制信道PUCCH资源集合。
应说明，步骤S310中的配置的第一PUCCH资源集合中的每一个PUCCH资源可以以子时隙级别(subslot-level)配置，也可以以时隙级别(slot-level)配置，本申请实施例对此不作限定。
应说明，第一PUCCH资源集合中的每一个PUCCH资源以子时隙级别配置可以理解为第一PUCCH资源集合中的每一个PUCCH资源的起始符号以子时隙边界做参考，即每一个PUCCH资源的起始符号为该子时隙的第一个符号到该子时隙长度(subslot length)个符号中的任意一个符号。第一PUCCH资源集合中的每一个PUCCH资源以时隙级别配置可以理解为第一PUCCH资源集合中的每一个PUCCH资源的起始符号以时隙边界做参考，即每一个PUCCH资源的起始符号为该时隙的第一个符号到该时隙长度(slot length)个符号中的任意一个符号。
在一些可能的实现方式中，该配置信息可以由网络设备通过高层消息发送至终端设备，该高层消息可以是无线资源控制(radio resource control，RRC)消息或者介质接入控制(media access control，MAC)层消息。网络设备可以通过下行信道发送上述高层消息，该下行信道可以是物理下行共享信道(physical downlink shared channel，PDSCH)，也可以是其它类型的下行信道，本申请对网络设备如何发送高层消息不作限定。
步骤S310与步骤S210类似，具体描述可参考步骤S210，此处为了简洁不再赘述。
S320，终端设备在第一PUCCH资源集合中的PUCCH资源上发送对下行数据的反馈信息。
其中，该PUCCH资源的起始符号在时隙中的至少一个子时隙中，该时隙中的每一个子时隙包括至少一个上行符号或灵活符号，其中，该至少一个上行符号或灵活符号中的第一个上行符号或灵活符号在该子时隙中的位置与该子时隙的起始符号的位置相差M个符号，M为非负整数，且M小于或等于该子时隙的长度。
现有技术中，每个子时隙中可用符号(上行符号或灵活符号)的位置灵活多变，有的子时隙中可用符号位于子时隙的头部，有的子时隙中可用符号位于子时隙的中间，有的子时隙中可用符号位于子时隙的尾部。网络设备针对所有的子时隙统一配置PUCCH资源集合，很难兼顾所有的子时隙的可能性，使得所有子时隙中有尽可能多的可用PUCCH资源。
在一些可能的实现方式中，方法300还包括步骤S330，终端设备获取至少一个子时隙的长度信息。
终端设备在获取到该至少一个子时隙的长度信息后，根据该长度信息将时隙划分为相应长度的子时隙。例如，该时隙长度为14个符号，该至少一个子时隙的长度信息为4个符号，则该时隙可以划分为长度为4个符号的子时隙1，长度为4个符号的子时隙2，,长度为4个符号的子时隙3以及长度为2个符号的子时隙4。
在一些可能的实现方式中，至少一个子时隙的长度信息为协议预配置或网络设备配置，本申请实施例对此并不作限定。
S340，终端设备确定时隙所包含的至少一个子时隙。
终端设备在获取到至少一个子时隙的长度信息后，根据该子时隙的长度信息以及所配置的上下行符号来确定该子时隙在时隙中的位置。
例如，终端设备从该时隙中的第一符号开始，直到第一个可用符号，并从该符号开始， 将连续的N个符号作为该子时隙，其中，N为小于或等于至少一个子时隙的长度的正整数。确定该时隙中的第一个子时隙后，继续查找，从下一个可用符号开始，将连续的N个长度的符号作为第二个子时隙，依次类推，直至该时隙的最后一个符号。划分完后，该时隙中的每一个子时隙的起始符号为第一个上行符号或灵活符号，即每个子时隙中第一个上行符号或灵活符号在该子时隙中的位置与该子时隙的起始符号的位置相差0个符号。
或者，终端设备从该时隙中的第一符号开始，直到第一个可用符号，并从该符号的前一个符号开始，将连续的N个符号作为该子时隙，其中，N为小于或等于至少一个子时隙的长度的正整数。确定该时隙中的第一个子时隙后，继续查找，从下一个可用符号的前一个符号开始，将连续的N个长度的符号作为第二个子时隙，依次类推，直至该时隙的最后一个符号。划分完后，该时隙中的每一个子时隙的第二个符号为第一个上行符号或灵活符号，即每个子时隙中第一个上行符号或灵活符号在该子时隙中的位置与该子时隙的起始符号的位置相差1个符号。
应理解，由于时隙中上下行符号的配置，使得每个子时隙中确定的N个符号可能包括可用符号或者不可用符号。根据M取值的不同，划分完后的子时隙中的第一个上行符号或灵活符号在子时隙中的位置可能不同，例如，第一个上行符号或灵活符号为子时隙的起始符号，或者为子时隙的第二个符号、第三个符号……但只要该时隙中的每个子时隙的第一个上行符号或灵活符号在子时隙中的位置相同即可，本申请对具体的划分方式并不作具体限定。
通过步骤S330和步骤S340，终端设备确定时隙所包含的至少一个子时隙，该时隙中的所有子时隙都包括至少一个上行符号或灵活符号，其中每个子时隙中的第一个上行符号或灵活符号的位置与距离该子时隙的起始符号的位置相差M个符号，即每个子时隙中的第一个上行符号或灵活符号在每个子时隙中的位置相同。网络设备在配置第一PUCCH资源集合时，可以遵循这一特性，从而减小网络设备统一配置第一PUCCH资源集合的复杂度。
网络设备在配置完第一PUCCH资源集合后，终端设备根据DCI中固有的N比特PUCCH资源指示(PUCCH resource indicator)域指示的索引值，从第一PUCCH资源集合中确定发送对上行数据的反馈信息的PUCCH资源。
如果该子时隙中可用的PUCCH资源个数不超过2 N个则终端设备直接根据PUCCH resource indicator域指示的索引值，从该第一PUCCH资源集合中确定用于发送上行反馈信息PUCCH资源。
或者，如果该子时隙中可用的PUCCH资源个数超过2 N个，则终端设备根据PUCCH resource indicator域指示的索引值以及该DCI在整个CORESET中的位置，从该第一PUCCH资源集合中确定用于发送上行反馈信息PUCCH资源。
终端设备在确定的PUCCH资源上发送包括HARQ-ACK消息的UCI，相应的，网络设备在确定的PUCCH资源上接收包括HARQ-ACK消息的UCI。
应说明，上述方法实施例中的步骤编号仅仅为举例说明，编号大小并不表示步骤的先后执行顺序，本申请实施例对此并不作限定。
上述技术方案中，终端设备将时隙划分为至少一个子时隙，子时隙包括至少一个上行符号或灵活符号，其中，该至少一个上行符号或灵活符号中的第一个上行符号或灵活符号 在所述子时隙中的位置与该子时隙的起始符号的位置相差M个符号，M为非负整数，且M小于或等于该子时隙的长度。该时隙划分后的每一个子时隙中的第一个上行符号或灵活符号的位置相同，网络设备在预配置第一PUCCH资源集合时，充分考虑这一点，避免配置的第一PUCCH资源集合中大量PUCCH资源不可用，在减小URLLC业务的反馈时延的同时降低了网络设备配置第一PUCCH资源集合的复杂度。
图4示出了本申请实施例提供的另一种通信方法500的示意性流程图。通信方法500可以应用于图1所示的通信系统，例如，可以由终端设备120或终端设备130执行，也可以由终端设备120中的芯片或终端设备130中的芯片执行。下面对图4所示的步骤510与步骤520进行详细的描述。
步骤510、终端设备接收配置信息。
其中，上述配置信息可以用于配置第一物理上行控制信道PUCCH资源集合，第一PUCCH资源集合是按照第一子时隙类型配置的。
需要说明的是，子时隙包括上行符号的数量可以与子时隙类型存在对应关系，即可以按照子时隙中所包含的不同上行符号的数量将子时隙分为不同子时隙类型。例如，子时隙中包含上行符号的数量为2的子时隙可以分为第一子时隙类型；子时隙中包含上行符号的数量为4的子时隙可以分为第二子时隙类型。
或者，子时隙在时隙中的位置可以与子时隙类型存在对应关系，即可以按照子时隙在时隙中的不同位置将子时隙分为不同子时隙类型。例如，位于时隙头部的子时隙可以分为第一子时隙类型；位于时隙中间的子时隙可以分为第二子时隙类型；位于时隙尾部的子时隙可以分为第三子时隙类型。
或者，子时隙包含上行符号的数量以及子时隙在时隙中的位置可以与子时隙类型存在对应关系，即可以按照子时隙中所包含的不同上行符号的数量以及子时隙在时隙中的不同位置将子时隙分为不同子时隙类型。例如，可以将包含相同数量的上行符号且位于时隙头部的子时隙分为第一子时隙类型；包含相同数量的上行符号且位于时隙中间的子时隙分为第二子时隙类型；包含相同数量的上行符号且位于时隙尾部的子时隙分为第三子时隙类型。
应理解，步骤510中的配置的第一PUCCH资源集可以是以子时隙类型级别配置的，即不同的子时隙类型可以对应不同的PUCCH资源集合；相同的子时隙类型可以对应一个PUCCH资源集合。
示例性地，第一PUCCH资源集合中的每一个PUCCH资源可以以子时隙级别配置的，也可以以时隙级别配置，本申请实施例对此不作限定。
应说明，第一PUCCH资源集合中的每一个PUCCH资源以子时隙级别配置可以理解为第一PUCCH资源集合中的每一个PUCCH资源的起始符号以子时隙边界做参考，即每一个PUCCH资源的起始符号为该子时隙的第一个符号到该子时隙长度(subslot length)个符号中的任意一个符号；或者，第一PUCCH资源集合中的每一个PUCCH资源以时隙级别配置可以理解为第一PUCCH资源集合中的每一个PUCCH资源的起始符号以时隙边界做参考，即每一个PUCCH资源的起始符号为该时隙的第一个符号到该时隙长度(slot length)个符号中的任意一个符号。
在一些可能的实现方式中，上述配置信息可以由网络设备通过高层消息发送至终端设 备，该高层消息可以是无线资源控制(radio resource control，RRC)消息或者介质接入控制(media access control，MAC)层消息。网络设备可以通过下行信道发送上述高层消息，该下行信道可以是物理下行共享信道(physical downlink shared channel，PDSCH)，也可以是其它类型的下行信道，本申请对网络设备如何发送高层消息不作限定。
步骤520、终端设备在确定对下行数据的反馈信息所在的子时隙为第一子时隙类型的情况下，在第一PUCCH资源集合中的PUCCH资源上发送反馈信息。
在本申请的实施例中，终端设备可以先确定对下行数据的反馈信息所在的子时隙的子时隙类型，根据子时隙类型确定该子时隙类型对应的PUCCH资源集合，在该PUCCH资源中的PUCCH资源上发送反馈信息。
示例性地，上述配置信息可以用于配置包含第一PUCCH资源集合的多个PUCCH资源集合，多个资源集合中的每一个PUCCH资源集合可以对应一个子时隙类型，在确定对下行数据的反馈信息所在的子时隙为第一子时隙类型的情况下，在第一PUCCH资源集合中的PUCCH资源上发送反馈信息可以是指从多个PUCCH资源集合中确定第一子时隙类型对应的第一PUCCH资源集合，在第一PUCCH资源集合中的PUCCH资源上发送反馈信息。
需要说明的是，多个PUCCH资源集合中的每一个PUCCH资源集合对应一个子时隙类型可以是指每一个PUCCH资源集合与子时隙类型为一一对应的关系，即不同的PUCCH资源集合对应不同的子时隙类型；或者，多个PUCCH资源集合中存在至少两个PUCCH资源集合可以对应一个相同的子时隙类型，本申请实施例对此不作任何限定。
示例性地，当多个PUCCH资源集合对应一个相同的子时隙类型时，可以先确定对下行数据的反馈信息所在的子时隙的子时隙类型，根据子时隙类型确定多个PUCCH资源集合中子时隙类型对应的M个PUCCH资源集合，再从M个PUCCH资源集合中选择一个PUCCH资源集合，M为大于1的整数。
例如，假设第一PUCCH资源集合与第二PUCCH资源集合均对应于第一子时隙类型，进一步可以根据准则从第一PUCCH资源集合与第二PUCCH资源集合中选择发送对下行数据的反馈信息的资源集合；其中，准则可以是指反馈信息占用的比特数，或者，准则可以是指通信质量要求，或者其它预设条件，本申请对此不作任何限定。
在本申请的实施例中由于多个资源集合中的每一个PUCCH资源集合可以对应一个子时隙类型，因此可以先确定对下行数据的反馈信息所在的子时隙的子时隙类型，然后根据该子时隙类型从多个PUCCH资源集合中选择该子时隙类型对应的PUCCH资源集合；换而言之，从多个PUCCH资源集合中确定第一子时隙类型对应的第一PUCCH资源集合可以是通过确定对下行数据的反馈信息所在的子时隙为第一子时隙类型，从而在多个PUCCH资源集合中确定第一子时隙类型对应的第一PUCCH资源集合。
下面对如何确定对下行数据的反馈信息所在的子时隙的子时隙类型进行描述，确定子时隙类型的方法包括但不限于以下三种方式：
方式一：可以根据子时隙中包括的上行符号的数量确定子时隙类型。
其中，上述子时隙是指对下行数据的反馈信息所在的子时隙。
情况1
可选地，上述从多个PUCCH资源集合中确定第一子时隙类型对应的该第一PUCCH 资源集合，包括：根据反馈信息所在的子时隙的上行符号的数量确定反馈信息所在的子时隙为第一子时隙类型。
需要说明的是，在本申请的实施例中，子时隙包括的上行符号的数量可以与子时隙类型存在对应关系。
示例性地，子时隙的长度可以为2个符号，则可以将时隙中的子时隙分为三个子时隙类型，比如，子时隙中包括0个上行符号的子隙可以为第一子时隙类型；子时隙中包括1个上行符号的子时隙可以为第二子时隙类型；子时隙中包括2个上行符号的子时隙可以为第三子时隙类型。
示例性地，子时隙的长度可以为4个符号，则可以将时隙中的子时隙分为五个子时隙类型，比如，子时隙中包括0个上行符号的子隙可以为第一子时隙类型；子时隙中包括1个上行符号的子时隙可以为第二子时隙类型；子时隙中包括2个上行符号的子时隙可以为第三子时隙类型；子时隙中包括3个上行符号的子时隙可以为第四子时隙类型；子时隙中包括4个上行符号的子时隙可以为第五子时隙类型。
同理，若子时隙的长度为7个符号，则可以将时隙中的子时隙分为八个子时隙类型。
情况2
可选地，上述从多个PUCCH资源集合中确定第一子时隙类型对应的该第一PUCCH资源集合，包括：根据反馈信息所在的子时隙的上行符号的数量与阈值确定反馈信息所在的子时隙为第一子时隙类型。
其中，上述阈值可以是一个阈值，也可以是多个阈值。
在一种可能的实现方式中，阈值可以是根据子时隙的长度信息确定的，比如，阈值可以为大于或等于0且小于子时隙长度的整数。
在另一种可能的实现方式中，阈值可以是协议配置的。
在另一种可能的实现方式中，阈值可以是网络侧设备通过高层信令配置的。
示例性地，子时隙的长度为7个符号，则子时隙中包括的上行符号的数量可以存在8种可能，分别为0～7个；阈值可以是指每个子时隙中至少包括的上行符号的数量，比如，阈值可以为4，则子时隙中包括上行符号的数量为0～3个的可以为第一子时隙类型；子时隙中包括上行符号数量为4～7个的可以为第二子时隙类型。
示例性地，子时隙的长度为7个符号，则子时隙中包括的上行符号的数量可以存在8种可能，分别为0～7个；阈值可以是指每个子时隙中至少包括的上行符号的数量，比如，阈值可以为2，4，6，则子时隙中包括0～1个上行符号的可以为第一子时隙类型；子时隙中包括2～3个上行符号的可以为第二子时隙类型；子时隙中包括4～5个上行符号的可以为第三子时隙；子时隙中包括6～7个上行符号的可以为第三子时隙类型。
需要说明的是，上述是以上行符号的数量与阈值进行举例说明，本申请对此不作任何限定。
在一种可能的实现方式中，上述上行符号的数量可以是指子时隙中包括的上行时域符号的数量。
在另一种可能的实现方式中，上述上行符号的数量可以是指子时隙中包括的上行时域符号与灵活符号的数量。
方式二：可以根据子时隙的在时隙中的位置确定子时隙类型。
可选地，上述从多个PUCCH资源集合中确定第一子时隙类型对应的第一PUCCH资源集合，包括：根据反馈信息所在的子时隙在时隙中的位置确定反馈信息所在的子时隙为第一子时隙类型。
示例性地，假设一个时隙中有P个子时隙，子时隙0～Q-1可以属于第一子时隙类型，子时隙Q～P-1可以属于第二子时隙类型；其中，阈值Q可以是网络设备配置的，或者，协议配置的。
例如，假设一个时隙中可以包括子时隙0～子时隙5，其中，位于时隙头部的子时隙0与子时隙1可以为第一子时隙类型；位于时隙中间位置的子时隙3可以为第二子时隙类型；位于时隙尾部的子时隙4与子时隙5可以为第三子时隙类型。
方式三：可以根据子时隙中包括的上行符号的数量以及子时隙在时隙中的位置确定子时隙类型。
示例性地，时隙中可以包括4个子时隙，分别为子时隙0～子时隙3，其中，子时隙0～子时隙2中均包括4个上行符号，子时隙3中包括2个上行符号；根据子时隙中包括的上行符号的数量则可以子时隙0～子时隙2可以对应同一子时隙类型，进一步地，根据子时隙在时隙中的位置可以将子时隙0～子时隙2的子时隙类型进行进一步地划分，比如，位于时隙头部的子时隙0可以为第一子时隙类型；位于时隙中间的子时隙1与子时隙2可以为第二子时隙类型；位于时隙尾部的子时隙3可以为第三子时隙类型。
在一种可能的实现方式中，上述上行符号的数量可以是指子时隙中包括的上行时域符号的数量。
在另一种可能的实现方式中，上述上行符号的数量可以是指子时隙中包括的上行时域符号与灵活符号的数量。
需要说明的是，上述方式一至方式三中确定子时隙类型的过程可以是终端设备执行的，同样也可以是网络设备执行的。
例如，对于终端设备，接收配置信息后需要确定反馈信息所在的子时隙的子时隙类型，从而在网络设备配置的多个PUCCH资源集合中确定该子时隙类型对应的PUCCH资源集合，在该PUCCH资源集中的PUCCH资源中发现反馈信息；对于网络设备而言，需要确定时隙中包括的多个子时隙的子时隙类型，从而根据子时隙类型确定为该子时隙类型配置的PUCCH资源集合，从而向终端设备发送配置信息，配置信息可以用于配置多个PUCCH资源集合，多个PUCCH资源集合中的每一个PUCCH资源集合可以对应一个子时隙类型。
在一种可能的实现方式中，上述通信方法还包括：接收符号分布信息，符号分布信息用于指示时隙中包括的上行符号、下行符号以及灵活符号的位置。
在本申请的实施例中，终端设备可以接收网络设备发送的符号分布信息，终端设备可以根据符号分布信息确定时隙的图案，即时隙中包括的上行符号、下行符号以及灵位符号的位置；进一步根据时隙的图案以及子时隙的长度信息确定子时隙的图案。
在本申请的技术方案中，可以根据不同的子时隙类型配置不同的PUCCH资源集合，通过可以能够充分考虑不同子时隙的属性，使得特征相似的子时隙，即相同子时隙类型的子时隙对应同一PUCCH资源集合，能够避免PUCCH资源集合中出现大量的不可用资源，实现减少下行信令中的冗余开销。
需要说明的是，在本申请的实施例中终端设备与网络设备可以先执行图3或图2所示 的通信方法再执行图4所示的通信方法，或者，在本申请的实施例中终端设备与网络设备可以先执行图3所示的通信方法，接着执行图4所示的通信方法，再执行图2所示的通信方法；即终端设备与网络设备执行的通信方法可以包含图2至图4所示的通信方法的多种组合方式，本申请对此不作任何限定。
例如，终端设备可以接收网络设备发送的第一配置信息，第一配置信息可以用于配置包含第一PUCCH资源集合的多个PUCCH资源集合，多个PUCCH资源集合中的每一个资源集合可以对应一个子时隙类型；终端设备可以从第一PUCCH资源集合中确定子时隙的第二PUCCH资源集合，第二PUCCH资源集合包括第一PUCCH资源集合中在子时隙中可用的PUCCH资源；在第二PUCCH资源集合中的可用的PUCCH资源上发送对下行数据的反馈信息。
例如，终端设备可以接收网络设备发送的配置信息，配置信息用于配置第一物理上行控制信道PUCCH资源集合；终端设备在第一PUCCH资源集合中的PUCCH资源上发送对下行数据的反馈信息，PUCCH资源的起始符号在时隙中的至少一个子时隙中，至少一个子时隙中的每一个子时隙包括至少一个上行符号或灵活符号，其中，至少一个上行符号或灵活符号中的第一个上行符号或灵活符号在子时隙中的位置与子时隙的起始符号的位置相差M个符号，M为非负整数，且M小于或等于所述子时隙的长度；上述PUCCH资源可以是终端设备从第一PUCCH资源集合中确定的可用的PUCCH资源，即PUCCH资源可以是从第一PUCCH资源集合中确定的子时隙中可用的第二PUCCH资源集合中的PUCCH资源。
例如，终端设备可以先确定子时隙的划分方式，即可以是时隙中的每一个子时隙包括至少一个上行符号或灵活符号，其中，该至少一个上行符号或灵活符号中的第一个上行符号或灵活符号在该子时隙中的位置与该子时隙的起始符号的位置相差M个符号，M为非负整数，且M小于或等于该子时隙的长度；终端设备接收网络设备发送的配置信息，配置信息可以用于配置包含第一PUCCH资源集合的多个PUCCH资源集合，多个PUCCH资源集合中的每一个PUCCH资源集合对应一个子时隙类型；终端设备可以从第一PUCCH资源集合中确定子时隙的第二PUCCH资源集合，第二PUCCH资源集合包括第一PUCCH资源集合中在子时隙中可用的PUCCH资源；在第二PUCCH资源集合中的可用的PUCCH资源上发送对下行数据的反馈信息。
应理解，上述方法实施例中的步骤编号仅仅为举例说明，编号大小并不表示步骤的先后执行顺序，本申请实施例对此并不作限定。
还应理解，上述举例说明是为了帮助本领域技术人员理解本申请实施例，而非要将本申请实施例限于所例示的具体数值或具体场景。本领域技术人员根据所给出的上述举例说明，显然可以进行各种等价的修改或变化，这样的修改或变化也落入本申请实施例的范围内。
