图4是本公开实施例提供的另一种通信设备的结构图。
具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
参见图1，图1是本公开实施例可应用的网络结构示意图，如图1所示，包括终端11和网络侧设备12，其中，终端11可以是用户终端(User Equipment，UE)或者其他终端设备，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)、机器人、车辆等终端侧设备，需要说明的是，在本公开实施例中并不限定终端的具体类型。网络侧设备12可以是基站，例如：宏站、LTE eNB、5G NR NB等；网络侧设备也可以是小站，如低功率节点(Low Power Node，LPN)、pico、femto等小站，或者网络侧设备可以接入点(Access Point，AP)；网络侧设备也可以是中央单元(Central Unit，CU)与其管理和控制的多个传输接收点(Transmission Reception Point，TRP)共同组成的网络节点。需要说明的是，在本公开实施例中并不限定网络侧设备的具体类型。本公开实施例中，通信设备可以是终端或者网络侧设备。
请参见图2，图2是本公开实施例提供的一种PUCCH资源确定方法的流程图，如图2所示，包括以下步骤：
201、确定PUCCH资源，以及确定PUCCH传输所在的子时隙(sub-slot)；
202、依据所述PUCCH资源，确定所述sub-slot中用于PUCCH传输的资源。
其中，上述sub-slot是指一个时隙(slot)划分得到的多个sub-slot中的一个或者多个sub-slot。例如：将一个slot划分为多个sub-slot，PUCCH可以在每个sub-slot中传输，即每个sub-slot均支持PUCCH传输。其中，一个slot可以被划分的sub-slot个数是可变的，例如：通过高层信令配置或者协议约定等。例如，一个slot(14个符号)可以被划分为两个sub-slot，则每个sub-slot的符号长度为7；又例如，一个slot可以被划分为4个sub-slot，则可以是两个sub-slot的符号长度为3，两个sub-slot的符号长度为4；又例如，一个slot可以被划分为7个sub-slot，则每个sub-slot的符号长度为2。
另外，上述确定PUCCH资源可以是在预先配置的PUCCH资源集合中选择的一个或者多个PUCCH资源，例如：根据PDCCH中的PUCCH资源指示域，在PUCCH资源集合中确定至少一个PUCCH资源。
而上述确定PUCCH传输所在的sub-slot可以是，根据所述PDCCH中的HARQ-ACK反馈时序指示域(即用于指示K1值的指示域)确定的时隙中的PUCCH传输所在的sub-slot。其中，上述K1可以是以sub-slot为单位，用于表示PDSCH(或者指示SPS PDSCH释放的PDCCH)结束位置到承载其HARQ-ACK的PUCCH传输所在的sub-slot之间的sub-slot间隔。例如：高层信令预先配置了8个K1值，当PDCCH调度一个PDSCH在时隙n中传输，该PDCCH中包含3比特HARQ-ACK反馈时序指示域，该指示域可以指示高层信令预先配置的8个K1值中的一个，假设该PDCCH中指示的K1＝4，则表示从该PDSCH的结束到承载起HARQ-ACK的PUCCH所在sub-slot之间间隔4个sub-slot，假设一个时隙中包含2个sub-slot，且PDSCH的结束位置为时隙n的结束位置，则可以确定PUCCH在时隙n+2中的第二个sub-slot中传输。本公开实施例中并不限定如何确定PUCCH传输所在的sub-slot，例如：如果高层信令只配置了1个K1值，则可以直接根据这个K1值基于PDSCH的结束位置确定对应的PUCCH传输所在的sub-slot，即此时K1值并不需要PDCCH指示，直接根据高层信令配置获得。也可以协议预先确定PUCCH传输所在的sub-slot与PDSCH(或者指示SPS PDSCH释放的PDCCH)所在 sub-slot的对应关系等。
上述依据所述PUCCH资源，确定所述sub-slot中用于PUCCH传输的资源可以是，确定所述sub-slot中与该PUCCH资源对应的资源作为用于PUCCH传输的资源。
需要说明的是，本公开实施例中，上述sub-slot中用于PUCCH传输的资源也可以称作上述sub-slot中的PUCCH资源，也就是说，上述用于PUCCH传输的资源也可以简称为PUCCH资源。另外，上述方法还可以包括：在上述用于PUCCH传输的资源上传输PUCCH，例如：终端在上述用于PUCCH传输的资源上发送PUCCH，网络侧设备在上述用于PUCCH传输的资源上接收PUCCH。
另外，上述方法中可以确定同一个时隙内多个sub-slot中用于PUCCH传输的资源，以在这多个sub-slot传输PUCCH，其中，每个sub-slot中确定用于PUCCH传输的资源的方式均可以采用上述步骤确定用于PUCCH传输的资源的方式，此处不作赘述。可选的，每个sub-slot可以传输一个或者多个PUCCH。
另外，本公开实施例中，PUCCH承载的内容包括但不限于HARQ-ACK、CSI和SR中的至少一项。
需要说明的是，上述方法可以应用于通信设备，例如：终端或者网络侧设备。
本公开实施例中，通过上述步骤可以根据PUCCH资源以及PUCCH传输所在的sub-slot，确定在所述sub-slot中的PUCCH资源，从而实现在不增加PUCCH资源配置开销的基础上，以sub-slot为单位确定PUCCH资源，进而能够支持在一个时隙中按照sub-slot的方式传输多个PUCCH资源，以提高PUCCH的传输效率。
作为一种可选的实施方式，上述PUCCH资源的起始符号为相对于所述sub-slot的起始位置的相对起始符号。
该实施方式中，由于PUCCH资源的起始符号为相对于所述sub-slot的起始位置的相对起始符号，从而将PUCCH资源与sub-slot边界相结合，确定sub-slot中的用于PUCCH传输的资源，以实现在时隙内包括多个sub-slot的 情况下，可以基于高层信令配置对多个sub-slot共享的PUCCH资源池，准确地确定上述sub-slot中用于传输PUCCH的资源。
例如：上述PUCCH资源的PUCCH起始符号编号为#1，占用2个符号，上述sub-slot为时隙n+2中的第四个sub-slot，则上述用于传输PUCCH的资源为第四个sub-slot中的第2个符号开始，占用2个符号传输PUCCH，即在第四个sub-slot中的第2、3个符号上传输承载PUCCH。
作为一种可选的实施方式，上述确定PUCCH资源包括：
根据PDCCH中的PUCCH资源指示域，在PUCCH资源集合中确定至少一个PUCCH资源；或者
确定高层信令配置的至少一个PUCCH资源。
其中，上述PDCCH可以是调度PDSCH的PDCCH，或者可以是指示SPS PDSCH release的PDCCH等，对此不作限定。
另外，上述PUCCH资源集合可以是高层信令配置给终端的，或者协议约定的等。
可选的，上述根据PDCCH中的PUCCH资源指示域，在PUCCH资源集合中确定至少一个PUCCH资源，可以包括：
当由PDCCH调度的PDSCH需要在所述sub-slot中进行HARQ-ACK反馈，和/或，指示SPS PDSCH释放的PDCCH需要在所述sub-slot中进行HARQ-ACK反馈时，根据在所述sub-slot中传输的包括HARQ-ACK在内的UCI的比特数，在一组PUCCH资源集合中选择PUCCH资源集合，并根据所述PDCCH中的PUCCH资源指示域，在所述PUCCH资源集合中确定至少一个PUCCH资源。
上述所述一组PUCCH资源集合包含一个或多个PUCCH资源集合，且每个PUCCH资源集合各个有对应的UCI的比特数。例如：高层信令可以配置一组PUCCH资源集合包含1到4个PUCCH资源集合，不同的PUCCH资源集合对应不同的UCI比特数，每一个PUCCH资源集合中包含多个PUCCH资源；其中，第一个PUCCH资源集合用于承载不超过2比特UCI传输，第二个PUCCH资源集合用于承载3到N1比特UCI传输，第三个PUCCH资源集合用于承载N1+1到N2比特UCI传输，第四个PUCCH资源集合用于承载 N2+1到1706，其中N1和N2为高层信令配置的，或者协议中约定的正整数。如果配置了不超过2个集合，则不需要配置N1，当配置了2个集合时，N1固定为1706，如果配置了不超过3个集合，则不需要配置N2，当配置了3个集合时，N2固定为1706。第一个PUCCH资源集合可以包含最多32个PUCCH资源，其余PUCCH资源集合包含最多8个PUCCH资源。
需要说明的是，上述包括HARQ-ACK在内的UCI的比特数可以是，仅HARQ-ACK，或者HARQ-ACK和CSI，或者HARQ-ACK和SR，或者HARQ-ACK、CSI以及SR。
可选的，所述一组PUCCH资源集合内的PUCCH资源适用于时隙slot内的多个sub-slot。
其中，上述一组PUCCH资源集合内的PUCCH资源适用于时隙slot内的多个sub-slot可以是，高层信令可以对支持在sub-slot中传输PUCCH的终端仅配置一组PUCCH资源集合，资源集合中的资源可以按照上述规则应用于任何一个sub-slot中，即该一组PUCCH资源集合对时隙内的所有sub-slot是共享的。这样可以实现更多的sub-slot支持PUCCH传输，从而进一步提高PUCCH的传输效率。
可选的，当存在多个所述PDCCH时，所述PUCCH资源指示域为所述多个PDCCH中时域位置位于最后的PDCCH中的PUCCH资源指示域。如果在相同的时域位置存在多个PDCCH，则假定这多个PDCCH中的PUCCH资源指示域相同，或者按照频域资源从低到高或从高到低的顺序确定最后一个PDCCH，依据该PDCCH中的PUCCH资源指示域确定PUCCH资源。
其中，上述多个所述PDCCH可以是多个调度PDSCH的PDCCH，多个指示SPS PDSCH释放的PDCCH，或者调度PDSCH的PDCCH和指示SPS PDSCH释放的PDCCH的集合。
可选的，上述确定高层信令配置的至少一个PUCCH资源，可以包括：
在仅对SPS PDSCH进行HARQ-ACK反馈的情况下，确定高层信令配置给SPS PDSCH进行HARQ-ACK反馈的至少一个PUCCH资源；或者
在仅反馈信道状态信息CSI或在CSI对应的PUCCH资源上传输CSI和HARQ-ACK或在CSI对应的PUCCH资源上传输CSI、HARQ-ACK以及SR 的情况下，确定高层信令配置给CSI反馈的至少一个PUCCH资源；或者
在仅反馈SR或在SR对应的PUCCH资源上传输HARQ-ACK的情况下，确定高层信令配置给SR反馈的至少一个PUCCH资源；或者
在仅反馈CSI和调度请求SR的情况下，确定高层信令配置给CSI的至少一个PUCCH资源。
其中，上述在仅反馈信道状态信息CSI或在CSI对应的PUCCH资源上传输CSI和HARQ-ACK或在CSI对应的PUCCH资源上传输CSI、HARQ-ACK以及SR的情况下，确定高层信令配置给CSI反馈的至少一个PUCCH资源可以理解为如下：
在仅反馈信道状态信息CSI的情况下，确定高层信令配置给CSI反馈的至少一个PUCCH资源；或者
在CSI对应的PUCCH资源上传输CSI和HARQ-ACK的情况下，确定高层信令配置给CSI反馈的至少一个PUCCH资源；或者
在CSI对应的PUCCH资源上传输CSI、HARQ-ACK以及SR的情况下，确定高层信令配置给CSI反馈的至少一个PUCCH资源。
该实施方式中，由于可以直接确定高层信令配置的PUCCH资源，从而可以降低PDCCH的开销。
作为一种可选的实施方式，上述依据所述PUCCH资源，确定所述sub-slot中用于PUCCH传输的资源，包括：
依据所述PUCCH资源的PUCCH起始符号编号和PUCCH占用的符号数中的至少一项，确定所述sub-slot中用于PUCCH传输的资源。
其中，上述PUCCH资源的PUCCH起始符号编号和PUCCH占用的符号数可以是PUCCH资源所提供或者对应的PUCCH起始符号编号和PUCCH占用的符号数。也就是说，步骤201确定上述PUCCH资源可以是，确定PUCCH资源的PUCCH起始符号编号和PUCCH占用的符号数中的至少一项。
上述依据所述PUCCH资源的PUCCH起始符号编号和PUCCH占用的符号数中的至少一项，确定所述sub-slot中用于PUCCH传输的资源可以包括：
依据所述PUCCH资源的PUCCH起始符号编号，确定所述sub-slot中用于PUCCH传输的资源；或者
依据所述PUCCH资源的PUCCH占用的符号数中的至少一项，确定所述sub-slot中用于PUCCH传输的资源；或者
依据所述PUCCH资源的PUCCH起始符号编号和PUCCH占用的符号数，确定所述sub-slot中用于PUCCH传输的资源。
其中，上述依据所述PUCCH资源的PUCCH起始符号编号，确定所述sub-slot中用于PUCCH传输的资源的情况下，PUCCH占用的符号数可以预先配置，或者协议约定。上述依据所述PUCCH资源的PUCCH占用的符号数中的至少一项，确定所述sub-slot中用于PUCCH传输的资源的情况下，PUCCH起始符号编号可以预先配置，或者协议约定。
该实施方式中，由于依据所述PUCCH资源的PUCCH起始符号编号和PUCCH占用的符号数中的至少一项，确定所述sub-slot中用于PUCCH传输的资源，从而可以准确地确定出sub-slot中用于PUCCH传输的资源。
可选的，依据所述PUCCH资源的PUCCH起始符号编号和PUCCH占用的符号数中的至少一项，确定所述sub-slot中用于PUCCH传输的资源，可以包括：
依据所述PUCCH资源的PUCCH起始符号编号和PUCCH占用的符号数，确定所述sub-slot中第s+1个符号开始，占用L个符号传输所述PUCCH，其中，所述s为所述PUCCH起始符号编号，且所述s从0开始编号，所述L为所述PUCCH占用的符号数。
例如：确定在时隙n+1中的第一个sub-slot中传输PUCCH，则假定确定的PUCCH资源的PUCCH起始符号编号为#1，占用2个符号，则在时隙n+1中的第1个sub-slot中的第二个符号开始，占用2个符号传输PUCCH，即在第1个sub-slot中的第2、3个符号上传输PUCCH。
可选的，依据所述PUCCH资源的PUCCH起始符号编号和PUCCH占用的符号数中的至少一项，确定所述sub-slot中用于PUCCH传输的资源，可以包括：
依据所述PUCCH资源的PUCCH起始符号编号、PUCCH占用的符号数和所述sub-slot的起始符号，确定所述sub-slot中用于PUCCH传输的资源为：
以所述sub-slot所在的时隙中的编号为s+j的符号开始，占用L个符号， 其中，所述s为所述PUCCH起始符号编号，且所述s从0开始编号，所述j为所述sub-slot的起始符号在所述时隙中的编号，且所述j从0开始编号，所述L为所述PUCCH占用的符号数。
例如：确定在时隙n+1中的第二个sub-slot中传输PUCCH，则假定确定的PUCCH资源的PUCCH起始符号编号为#1，占用2个符号，则由于第二个sub-slot的起始符号编号j＝4，则可以确定第二个sub-slot中的PUCCH在时隙n+2中的编号为s+j＝1+4＝5的符号开始，占用2个符号传输，即在时隙n+1中的编号为5和6的符号(即第6和第7个符号)上传输。
需要说明的是，本公开实施例中并不限定，上述s和j从0开始编号，例如：在一些场景中，s也可以是从1开始，这样可以确定所述sub-slot中第s个符号开始，占用L个符号传输所述PUCCH。
可选的，若依据所述PUCCH资源确定的用于PUCCH传输的时域位置跨越所述sub-slot的边界，则所述sub-slot中用于PUCCH传输的截止符号为所述sub-slot的结束符号。
其中，上述依据所述PUCCH资源确定的用于PUCCH传输的时域位置跨越所述sub-slot的边界是指：
依据所述PUCCH资源确定的用于PUCCH传输的符号数超过所述sub-slot的符号数；和/或，
依据所述PUCCH资源确定的用于PUCCH传输的结束符号在所述sub-slot的结束符号之后。
例如：假定选择的PUCCH资源对应的PUCCH起始符号编号为#1，占用3个符号，则在时隙n+2中的第二个sub-slot中的第二个符号开始，占用3个符号传输PUCCH，则占用时隙n+2中的编号为5、6、7的符号传输，则最后一个符号超过了第二个sub-slot的边界，落在了第三sub-slot中，此时，终端和网络侧设备对这种情况统一采用截短方式，即直接确定第二个sub-slot中的该PUCCH仅占用时隙n+2中的编号为5、6的两个符号传输，按照两个符号的传输来确定相关的传输参数，如时域正交序列等。
该实施方式中，由于网络侧设备和终端对该截短行为的理解一致，从而不会出现传输和接收不对应的错误，以提高PUCCH的传输可靠性。
可选的，还可以总是认为依据所述PUCCH资源确定的用于PUCCH传输的时域位置不跨越所述sub-slot的边界。
例如：终端侧则总是假定依据所述PUCCH资源确定的用于PUCCH传输的时域位置不跨越所述sub-slot的边界，从而可以直接根据PUCCH资源来确定sub-slot中的用于PUCCH传输的时域位置，认为这样确定出的PUCCH传输的时域位置总是不会跨域sub-slo边界的，即终端不期望依据所述PUCCH资源确定的用于PUCCH传输的时域位置跨越所述sub-slot的边界，如果出现了这种情况，则终端可能认为是网络侧的调度或指示或配置错误。
例如：网络侧设备在进行配置时，确保依据所述PUCCH资源确定的用于PUCCH传输的时域位置不跨越所述sub-slot的边界。即在通过高层信令配置PUCCH资源集合或PUCCH资源给终端时，例如上述通过高层信令配置PUCCH资源集合中的每个一个PUCCH资源，或者通过高层信令配置给SPS PDSCH的HARQ-ACK的PUCCH资源，或者通过高层信令配置给CSI的PUCCH资源，或者通过高层信令配置给SR的PUCCH资源，在配置这些PUCCH资源中的每一个PUCCH资源时，都以包含符号数最少的sub-slot为依据，以保证在任何一个sub-slot中按照任何一个PUCCH资源确定这个sub-slot中的用于PUCCH传输的时域位置时，该时域位置都不会跨越sub-slot边界。或者，网络侧在配置PUCCH资源时，不保证根据其中部分PUCCH资源确定sub-slot中的用于PUCCH传输的时域位置不跨越所述sub-slot的边界，则需要在PDCCH设置合理的PUCCH资源指示域，以合理选择一个PUCCH资源，保证根据该PUCCH资源来确定sub-slot中的用于PUCCH传输的时域位置不跨越所述sub-slot的边界。
其中，上述依据所述PUCCH资源确定的用于PUCCH传输的时域位置不跨越所述sub-slot的边界，可以包括：
所述PUCCH资源对应的PUCCH占用的符号数小于或者等于一个时隙中符号数最少的sub-slot的符号数；和/或，
依据所述PUCCH资源对应的PUCCH起始符号编号和PUCCH占用的符号数确定的在一个sub-slot中传输的PUCCH的截止符号不超过一个时隙中符号数最少的sub-slot的截止符号。
例如：假定网络侧设备在配置PUCCH资源集合给终端时，考虑了一个时隙中所划分的sub-slot中的最小sub-slot，即按照最小sub-slot的长度为3个符号，确定所配置的任何一个PUCCH资源的长度都不超过3个符号，且起始符号和符号长度作用的最终结果不会导致PUCCH所占用的符号跨越sub-slot边界，即s+L不超过3，即如果s＝0，即起始符号为时隙中的第一个符号，则L可以为1、2、3，从而保证终止符号最远为长度是3的sub-slot的结束符号。如果s＝1，则L可以为1、2，如果s＝2，则L＝1。则例如，假定选择的PUCCH资源对应的PUCCH起始符号编号为#1，占用2个符号，则在时隙n+2中的第二个sub-slot中的第二个符号开始，占用2个符号传输PUCCH，即在第二个sub-slot中的第2、3个符号上传输承载上述4比特HARQ-ACK的PUCCH。此时如果转换为时隙n+2中的符号编号，则由于第二个sub-slot的起始符号编号j＝4，则可以确定第二个sub-slot中的PUCCH在时隙n+2中的编号为s+j＝1+4＝5的符号开始，占用2个符号传输，即在时隙n+2中的编号为5和6的符号上传输。
又例如：网络侧设备在配置PUCCH资源集合给终端时，配置了一个PUCCH资源1对应起始符号编号为#0，占用4个符号，配置了另一个PUCCH资源2对应起始符号编号为#1，占用2个符号，则如果基站发送一个PDCCH调度PDSCH在一个时隙中的仅包含3个符号的sub-slot中传输PUCCH，则需要通过该PDCCH中的PUCCH资源指示域指示PUCCH资源2，而避免指示PUCCH资源1给终端，从而保证终端在包含3个符号的sub-slot中根据指示的PUCCH资源确定的用于PUCCH传输的时域位置不跨越所述sub-slot的边界。
该实施方式中，可以保证依据所述PUCCH资源确定的用于PUCCH传输的时域位置不跨越所述sub-slot的边界，从而提高PUCCH的传输可靠性。
本公开实施例中，确定PUCCH资源，以及确定PUCCH传输所在的sub-slot；依据所述PUCCH资源，确定所述sub-slot中用于PUCCH传输的资源。这样可以实现以sub-slot为单位确定PUCCH资源，相比slot为单位确定PUCCH资源，本公开实施例可以提高PUCCH的传输效率。
下面以一个时隙中被划分了4个sub-slot进行举例说明：
实施例：
假设一个时隙中被划分了4个sub-slot，其中第一和第四个sub-slot长度为4符号，第二个和第三个sub-slot长度为3符号。假设根据调度PDSCH的PDCCH中的K1指示(以sub-slot为单位，用于表示PDSCH结束位置到传输其HARQ-ACK的sub-slot之间的sub-slot间隔)，确定存在4个PDSCH需要在时隙n+2中的第二个sub-slot中进行HARQ-ACK反馈，确定存在2个PDSCH需要在时隙n+2中的第四个sub-slot中进行HARQ-ACK反馈。假设每个PDSCH对应1比特HARQ-ACK；假设高层信令预先给终端配置了2个PUCCH资源集合，第一个PUCCH资源集合各包含8个资源，对应传输1到2比特UCI，每个PUCCH资源的具体信息包括对应的PUCCH格式(格式0或格式1)、PUCCH起始符号编号(假设从0开始)、PUCCH占用符号个数、占用的RB编号、循环移位编号、正交序列编号(格式1)等针对某种PUCCH格式所需要的信息；第二个PUCCH资源集合各包含8个资源，对应传输2比特以上UCI，每个PUCCH资源的具体信息包括对应的PUCCH格式(格式2或格式3或格式4)、PUCCH起始符号编号、PUCCH占用符号个数、起始RB编号、占用的RB个数(格式2和格式3)、正交序列编号(格式4)等针对某种PUCCH格式所需要的信息。其中，PUCCH起始符号编号是相对于sub-slot的边界配置的，即如果一个PUCCH资源对应的PUCCH起始符号编号为#0，则说明是一个sub-slot中的第1个符号，该符号对应到一个时隙中的符号编号则基于sub-slot的起始符号编号j来确定，即为j+0＝j；上述两个PUCCH资源集合对于每个sub-slot都是共享的，即仅配置这两个PUCCH资源集合，应用于所有sub-slot中的PUCCH传输。
在时隙n+2中的第二个sub-slot中，根据HARQ-ACK码本(codebook)的确定方法，假设确定需要反馈4比特HARQ-ACK，则根据4比特UCI传输选择第二个PUCCH资源集合，根据需要在该sub-slot进行HARQ-ACK反馈的4个PDSCH所对应的PDCCH(即调度这些PDSCH的PDCCH)中的最后一个PDCCH中的PUCCH资源指示域，在第二个PUCCH资源集合中的8个PUCCH资源中选择一个PUCCH资源：
方法1：假定网络侧设备在配置PUCCH资源集合给终端时，考虑了一个 时隙中所划分的sub-slot中的最小sub-slot，即按照最小sub-slot的长度为3个符号，确定所配置的任何一个PUCCH资源的长度都不超过3个符号，且起始符号和符号长度作用的最终结果不会导致PUCCH所占用的符号跨越sub-slot边界，即s+L不超过3，即如果s＝0，即起始符号为时隙中的第一个符号，则L可以为1、2、3，从而保证终止符号最远为长度是3的sub-slot的结束符号，如果s＝1，则L可以为1、2，如果s＝2，则L＝1；则例如，假定选择的PUCCH资源对应的PUCCH起始符号编号为#1，占用2个符号，则在时隙n+2中的第二个sub-slot中的第二个符号开始，占用2个符号传输PUCCH，即在第二个sub-slot中的第2、3个符号上传输承载上述4比特HARQ-ACK的PUCCH。此时如果转换为时隙n+2中的符号编号，则由于第二个sub-slot的起始符号编号j＝4，则可以确定第二个sub-slot中的PUCCH在时隙n+2中的编号为s+j＝1+4＝5的符号开始，占用2个符号传输，即在时隙n+2中的编号为5和6的符号上传输。
方法2：不存在上述配置上的假定，则可能会出现s+L超过一个sub-slot的最大长度，从而出现根据PUCCH资源确定的在一个sub-slot中的PUCCH的传输符号跨越sub-slot边界，此时，可以对超出边界的部分进行截短，例如假定选择的PUCCH资源对应的PUCCH起始符号编号为#1，占用3个符号，则在时隙n+2中的第二个sub-slot中的第二个符号开始，占用3个符号传输PUCCH，则占用时隙n+2中的编号为5、6、7的符号传输，则最后一个符号超过了第二个sub-slot的边界，落在了第三sub-slot中，此时，终端和网络侧设备对这种情况统一采用截短方式，即直接确定第二个sub-slot中的该PUCCH仅占用时隙n+2中的编号为5、6的两个符号传输，按照两个符号的传输来确定相关的传输参数，如时域正交序列等，由于基站和终端对该截短行为的理解一致，不会出现传输和接收不对应的错误。
另外，在时隙n+2中的第四个sub-slot中，根据HARQ-ACK codebook的确定方法，假设确定需要反馈2比特HARQ-ACK，则根据2比特UCI传输选择第一个PUCCH资源集合，根据需要在该sub-slot进行HARQ-ACK反馈的2个PDSCH所对应的PDCCH(即调度这些PDSCH的PDCCH)中的最后一个PDCCH中的PUCCH资源指示域，在第一个PUCCH资源集合中的8 个PUCCH资源中选择一个PUCCH资源：
方法1：同上，此时由于第四个sub-slot包含4个符号，而PUCCH资源总是按照s+L不会超过3来配置，因此在包含4个符号的sub-slot中总是不会出现跨越sub-slot边界的问题，假定选择的PUCCH资源对应的PUCCH起始符号编号为#1，占用2个符号，则在时隙n+2中的第四个sub-slot中的第2个符号开始，占用2个符号传输PUCCH，即在第四个sub-slot中的第2、3个符号上传输承载上述2比特HARQ-ACK的PUCCH，此时如果转换为时隙n+2中的符号编号，则由于第四个sub-slot的起始符号编号j＝10，则可以确定第四个sub-slot中的PUCCH在时隙n+2中的编号为s+j＝1+10＝11的符号开始，占用2个符号传输，即在时隙n+2中的编号为11和12的符号上传输。
方法2：同上，不做配置限制，例如根据一个时隙中的包含符号数最大的sub-slot的长度进行PUCCH资源配置，则可以配置s+L＝4的情况，例如假定选择的PUCCH资源对应的PUCCH起始符号编号为#0，占用4个符号，则在时隙n+2中的第四个sub-slot中的第1个符号开始，占用4个符号传输PUCCH，则占用第四个时隙的所有符号传输，即占用时隙n+2中的编号为10、11、12、13的符号传输，此时并未超过sub-slot边界；又例如，还可能配置s+L>4，例如假定选择的PUCCH资源对应的PUCCH起始符号编号为#1，占用4个符号，则在时隙n+2中的第四个sub-slot中的第2个符号开始，占用4个符号传输PUCCH，则最后一个符号超过第四个sub-slot的边界，进行截短，则确定PUCCH占用第四个sub-slot的所有符号传输，即占用时隙n+2中的编号为10、11、12、13的符号传输，按照4个符号的传输来确定相关的传输参数，如时域正交序列等，由于基站和终端对该截短行为的理解一致，不会出现传输和接收不对应的错误。
需要说明的是，上述实施例中，如果根据K1确定在时隙n+2中的其他sub-slot中传输，或在其他时隙中的传输，处理方法是相同的。例如：对于原本在时隙n+2中的第2个sub-slot传输的4个PDSCH，如果根据K1确定在时隙n+1中的第一个sub-slot中传输，则假定确定的PUCCH资源同上，即选择的PUCCH资源对应的PUCCH起始符号编号为#1，占用2个符号，则在时隙n+1中的第1个sub-slot中的第二个符号开始，占用2个符号传输PUCCH， 即在第1个sub-slot中的第2、3个符号上传输承载上述4比特HARQ-ACK的PUCCH。此时如果转换为时隙n+1中的符号编号，则由于第1个sub-slot的起始符号编号j＝0，则可以确定第1个sub-slot中的PUCCH在时隙n+1中的编号为s+j＝1+0＝1的符号开始，占用2个符号传输，即在时隙n+1中的编号为1和2的符号上传输。可见，PUCCH资源集合中的同一个PUCCH资源，在作用于不同的sub-slot时都可以使用，但最终确定的实际的PUCCH时域位置随着sub-slot的位置发生变化，因此，实现配置的同一个PUCCH资源对所有sub-slot的共享，从而避免对每个sub-slot独立配置PUCCH资源带来的配置复杂度和配置开销。
需要说明的是，上述实施例仅以对应PDCCH调度的PDSCH的HARQ-ACK传输的PUCCH资源确定为例，如果还存在CSI和/或SR与上述HARQ-ACK同时传输，则确定PUCCH资源集合时的UCI考虑所有UCI的总比特即可，其他行为与上述一致。如果替换为SPS PDSCH的HARQ-ACK反馈(SPS HARQ-ACK)，或CSI传输，或SR传输，类似，只不过确定的PUCCH资源是高层信令预先配置给SPS HARQ-ACK或CSI或SR的PUCCH资源。如果为SPS HARQ-ACK，则可以根据对应的K1值确定对应的传输所在的sub-slot，基于高层配置的PUCCH资源中的起始符号确定在该sub-slot中的起始符号，以及是否需要截短，按照确定的符号位置进行传输，如果是CSI或SR，则可以根据周期配置确定对应的传输所在的sub-slot，基于高层配置的PUCCH资源中的起始符号确定在该sub-slot中的起始符号，以及是否需要截短，按照确定的符号位置进行传输。
需要说明的是，上述实施例中，根据确定的PUCCH资源进一步确定在一个sub-slot中的PUCCH资源时，仅确定sub-slot中的时域资源位置即可，其他信息，如资源块(Resource Block，RB)位置、初始循环移位等信息可以采用协议中已定义的方式进行确定，或者采用后续协议版本新定义的方式进行确定，对此本公开实施例不作限定。
另外，上述实施例中，仅以一个时隙被划分为4个sub-slot为例，其中4个sub-slot划分方式也仅为示例，其他划分方式、其他sub-slot个数都适用于上述方法。
本公开实施例中，可以实现将PUCCH资源与sub-slot边界相结合，确定一个sub-slot中的PUCCH资源，其中，当根据PUCCH资源确定的PUCCH的时域位置跨越sub-slot边界时，确定在所述sub-slot中传输的PUCCH的截止符号为所述sub-slot的结束符号，或者，总是假定PUCCH资源是基于一个时隙中的符号数最少的sub-slot的符号长度进行配置，从而保证每一个PUCCH资源在一个sub-slot中都不会超过sub-slot边界。
本公开实施例提供了一种当支持一个时隙中按照sub-slot的方式传输多个承载HARQ-ACK的PUCCH时的PUCCH资源配置方法，通过仅配置对所有sub-slot共享的PUCCH资源集合，结合sub-slot之间的固定符号偏移，实现对所有sub-slot中的PUCCH资源的配置，从而保证在不增加配置开销的基础上，实现终端在每个sub-slot中可以灵活获得PUCCH资源
