技术领域
本公开涉及通信技术领域，尤其涉及一种载波切换的传输处理方法及装置。
背景技术
在第五代新无线系统(5 Generation New RAT，5G NR)中，大量存在低时延高可靠通信(Ultra-Reliable and Low Latency Communication，URLLC)业务，URLLC业务中的一个重要指标就是低时延。但是，URLLC的上行控制信息(Uplink Control Information，UCI)传输时延会影响URLLC业务的传输时延，比如混合自动重传请求确认(Hybrid Automatic Repeat request-ACKnowledgment，HARQ-ACK)，反馈的时延会影响物理下行共享信道(Physical Downlink Shared Channel，PDSCH)的重传，信道状态信息(Channel State Information，CSI)反馈的时延会影响PDSCH的调度，从而影响下行业务的时延；调度请求(Scheduling Request，SR)的时延会影响物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的时延，从而影响上行业务的时延。
并且，考虑到非配对频谱上的上行传输和下行传输共享同一个频谱资源，则需要上行和下行进行时分复用(Time Division Multiplexing，TDM)传输。因此，在一个载波组中，配置传输物理上行控制信道(Physical Uplink Control Channel，PUCCH)的载波上可能受限于上下行配比，不能在满足下行传输的处理时间最近的时域位置找到可用的上行资源(如满足处理时延的位置刚好是下行传输的时域位置)，此时，如果等到传输PUCCH的载波上的可用上行资源，则会造成传输时延，影响URLLC性能。
目前为了降低PUCCH传输时刻，提出的一种解决方案是进行PUCCH载波切换，即将PUCCH从原本配置传输的载波切换到另一个载波上传输，从而不需要在原载波调度资源不足或者资源冲突的时候导致需要延迟进行PUCCH传输。这样，如何使用PUCCH载波切换的方式进行PUCCH传输已成为亟待解决的问题。

下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，并不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
应该知道的是，UCI包含HARQ-ACK，CSI，SR等信息。其中，HARQ-ACK是ACK和NACK的统称，用于针对PDSCH或指示半持续调度(Semi-Persistent Scheduling，SPS)资源释放的物理下行控制信道(Physical Downlink Control Channel，PDCCH)(又称SPS PDSCH release)进行反馈，告知基站PDSCH或指示SPS PDSCH释放的PDCCH是否正确接收；CSI用于反馈下行信道质量，从而帮助基站更好的进行下行调度，例如根据CSI进行调制和编码方案(Modulation and Coding Scheme，MCS)选择、配置适当的资源块(Resource Block，RB)资源等；SR用于当终端有上行业务需要传输时，向基站请求携带上行业务的PUSCH的传输资源。UCI在PUCCH上传输。PUCCH总是在固定的载波上传输。
对于载波聚合(Carrier aggregation，CA)场景，PUCCH在主载波(Primary Component Carrier，PCC)(或主小区(Primary Cell，PCell)，下同)上传输，当CA场景中配置了PUCCH在辅载波(Secondary Component Carrier， SCC)(或辅小区(Secondary Cell，SCell)，下同)上传输时，聚合的载波可以分为两个PUCCH载波组，每个PUCCH载波组中存在一个指定的载波传输PUCCH，包含PCC的载波组为主PUCCH载波组，PUCCH在PCC上传输，辅PUCCH载波组中都是SCC，高层信令配置其中一个SCC上可以传输PUCCH，称之为PUCCH SCell，每个载波组中的所有载波上的下行传输(包括PDSCH、下行控制信息(Downlink Control Information，DCI)触发的type3HARQ-ACK码本传输、需要进行HARQ-ACK反馈的PDCCH，比如指示SPS资源释放的PDCCH，指示SCell dormancy的PDCCH等)的HARQ-ACK都在一个指定的载波上的PUCCH中传输。对于双连接(Dual-connective，DC)场景，存在主载波组(Master Carrier Group，MCG)和辅载波组(Secondary Carrier Group，SCG)两个载波组，在每个载波组中一个指定的载波上传输PUCCH，其中MCG包含PCC，PUCCH在PCC上传输，SCG中都是SCC，PUCCH在其中一个预先配置的SCC(或称为PSCell)上传输。
5G NR中支持灵活的定时关系。对于具有动态调度(即PDCCH或DCI调度的传输)的下行传输，包括PDCCH调度的PDSCH，DCI触发的type3HARQ-ACK码本传输，需要进行HARQ-ACK的PDCCH本身，例如指示下行资源释放的PDCCH，指示SCell dormancy的PDCCH，等HARQ-ACK传输所在的时隙或子时隙是可以基于对应的PDCCH或DCI(PDCCH和DCI可以认为等价，DCI是PDCCH的具体传输格式，PDCCH是DCI的传输信道)中的反馈定时指示域来确定。以PDSCH为例，承载其调度信息的PDCCH指示PDSCH与PDCCH之间的调度定时关系(Scheduling timing，即K0)以及PDSCH到其对应的HARQ-ACK之间的反馈定时关系(HARQ-ACK timing，即K1)。具体地，PDCCH所使用的DCI格式中的时域资源分配指示域指示PDSCH所在时隙与DCI所在时隙的时隙偏移K0；DCI格式中的PDSCH到HARQ-ACK反馈定时指示域指示PDSCH结束到HARQ-ACK开始之间的时隙个数K1，即假设上行和下行子载波间隔(Sub-Carrier Space，SCS)相同时，时隙n中传输的PDSCH在时隙n+K1中进行HARQ-ACK传输。
K1的全集为{0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15}，通常会配置给终端最多8个值。其中，K1的值是以时隙(slot)为单位的，即K1＝1表示间隔1 个时隙。此外，K1的值可以是以时隙或者子时隙(sub-slot)为单位，其中子时隙可以预先配置为2个符号长度(即一个时隙中顺序存在7个子时隙)，或者7个符号长度(即一个时隙中顺序存在2个子时隙)等。DCI中是否存在反馈定时指示域可以根据高层信令配置的指示比特数是否大于0得到，也可以根据高层信令配置的反馈定时的后选值K1集合中的元素个数来确定，当元素个数大于1个时，按照元素个数确定指示的比特数(例如ceil(log 2N)，N为元素个数，ceil为向上取整)，当元素个数仅有一个时，DCI中不存在指示域，直接使用这一个值确定反馈定时。
对于半静态的UCI，例如CSI、SR以及对应SPS PDSCH的HARQ-ACK(简称SPS HARQ-ACK)，承载半静态UCI的PUCCH传输所在的时隙或者子时隙是半静态确定的，称之为半静态的反馈时序。例如CSI和SR是根据高层信令配置的周期和偏移值，确定每个传输机会所在的时隙以及时隙中的符号位置，从而周期性的在对应的时隙以及相应的符号位置中使用高层信令配置的PUCCH资源进行传输。SPS HARQ-ACK则是可以根据指示SPS PDSCH激活的PDCCH中的反馈定时指示域所指示的K1值确定HARQ-ACK反馈位置(即所在时隙或子时隙)，当然，如果指示SPS PDSCH激活的PDCCH中如果不存在反馈定时指示域，则按照高层信令配置的一个K1值确定HARQ-ACK反馈位置。
承载CSI或SR的PUCCH资源是高层信令对每个CSI报告(report)或SR配置分别配置的一个PUCCH资源。系统中可以为承载具有动态调度的下行传输的HARQ-ACK配置一个或多个PUCCH资源集合，如果仅配置一个PUCCH资源集合，则承载具有动态调度的下行传输的HARQ-ACK的PUCCH资源可以是根据调度PDCCH中的PUCCH资源指示域从这个资源集合中的多个资源中选择的一个资源，如果一个资源集合中包含超过8个资源，可以结合PDCCH的CCE信息以及其中的PUCCH资源指示域共同在多个资源中选择的一个资源；如果配置了多个PUCCH资源集合，则每个PUCCH资源集合对应不同的UCI传输比特数，先根据PUCCH承载的UCI比特数选择其中一个PUCCH资源集合，在选择的PUCCH资源集合中，根据调度PDCCH中的PUCCH资源指示域从这个资源集合中的多个资源中选择的一个资源。 如果一个资源集合中仅存在一个PUCCH资源，则PDCCH中也可以不存在PUCCH资源指示域，直接使用这个资源进行传输即可。
本公开实施例提供了一种载波切换的传输处理方法及装置。其中，方法和装置是基于同一申请构思的，由于方法和装置解决问题的原理相似，因此装置和方法的实施可以相互参见，重复之处不再赘述。
如图1所示，本公开实施例提供的一种载波切换的传输处理方法，应用于网络侧设备或终端，包括：
步骤101，在第一载波上传输的物理上行控制信道PUCCH需要进行载波切换时，按照预定方式确定PUCCH载波切换后在第二载波上的第一PUCCH资源；
其中，所述第二载波为切换后传输PUCCH的载波。
如此，执行上述本公开实施例方法的设备，能够在需要进行PUCCH载波切换时，按照预定方式确定切换后载波上的PUCCH资源，从而不需要额外信令通知或指示的基础上，确定出在切换后的载波上传输PUCCH的PUCCH资源，保证PUCCH载波传输的正常实现，同时不增加额外信令开销。
其中，执行上述本公开实施例方法的设备，可以是网络侧设备或终端设备。但，对于终端设备，是在第二载波上确定的第一PUCCH资源上发送PUCCH，即不在第一载波上发送PUCCH，从而实现PUCCH从第一载波切换到第二载波上传输。对于网络侧设备(如基站)，则是在第二载波上确定的第一PUCCH资源上接收PUCCH，即不在第一载波上接收PUCCH，从而实现PUCCH从第一载波切换到第二载波上传输。
在该实施例中，可选地，所述按照预定方式确定PUCCH载波切换后在第二载波上的第一PUCCH资源，包括：
根据第二PUCCH资源的起始符号和符号长度，在所述第二载波上传输PUCCH的时间单元中确定一个PUCCH资源作为所述第一PUCCH资源；
其中，所述第二PUCCH资源是进行载波切换的PUCCH在所述第一载波上对应的PUCCH资源。
即，确定第一PUCCH资源的方式1是：根据进行载波切换的PUCCH在第一载波上对应的PUCCH资源的起始符号和符号长度，在第二载波上传输 PUCCH的时间单元中确定一个PUCCH资源为第一PUCCH资源。
此时，第一载波和第二载波上的时间单元的单位可以相同，也可以不同。时间单元的单位可以表现为时隙、子时隙中的一种，子时隙可以有不同的符号长度(比如长度为2个符号的子时隙，或者长度为7个符号的子时隙等)。
可选地，所述第一PUCCH资源的频域资源与所述第二PUCCH资源的频域资源(例如RB个数和位置)相同。
可选地，所述第一PUCCH资源的码域资源与所述第二PUCCH资源的码域资源(例如正交序列，循环移位等)相同。
当然，网络侧设备会在配置上保证按照该方式确定的RB集合不会超过第二载波的带宽范围，或者如果超过带宽范围，则仅在带宽范围所包含的RB中传输。
可选地，所述第一载波上传输PUCCH的时间单元和所述第二载波上传输PUCCH的时间单元的单位相同；或者，所述第一载波上传输PUCCH的时间单元小于或等于所述第二载波上传输PUCCH的时间单元。
如此，对于第一载波上传输PUCCH的时间单元1和所述第二载波上传输PUCCH的时间单元2：
时间单元1和时间单元2的单位相同，也就是两者具有一样的单位，如都是时隙，或都是相同长度的子时隙；
时间单元1小于或等于时间单元2，也就是时间单元1所包含的符号数小于或等于时间单元2所包含的符号数，如时间单元1为时隙，则时间单元2也为时隙；时间单元1为长度是7符号的子时隙，则时间单元2也可以为时隙或长度是7符号的子时隙。
其中，如果第二载波上没有配置PUCCH传输时间单元的类型，则确定按照与第一载波上相同的PUCCH传输时间单元或者预先约定的PUCCH传输时间单元进行传输。
该实施例中，可选地，所述按照预定方式确定PUCCH载波切换后在第二载波上的第一PUCCH资源，包括：
若需要进行载波切换的PUCCH具有对应的PDCCH，终端根据需要进行载波切换的PUCCH对应的最后一个PDCCH中的PUCCH资源指示域，在所 述第二载波上的预先配置的PUCCH资源集合中确定一个PUCCH资源作为所述第一PUCCH资源；
其中，所述预先配置的PUCCH资源集合包括一个或多个PUCCH资源集合；
或者，
若需要进行载波切换的PUCCH具有对应的PDCCH，网络侧设备在第二载波上的预先配置的PUCCH资源集合中确定一个PUCCH资源，确定所述PDCCH中的用于指示所述确定的PUCCH资源的PUCCH资源指示域，并将所述PDCCH发送给终端；
其中，所述预先配置的PUCCH资源集合包括一个或多个PUCCH资源集合。
其中，网络侧设备用于发送携带PUCCH资源指示域的PDCCH，终端用于接收携带PUCCH资源指示域的PDCCH。
可选地，所述按照预定方式确定PUCCH载波切换后在第二载波上的第一PUCCH资源，包括：
若需要进行载波切换的PUCCH没有对应的PDCCH，则在第二载波上预先配置的对应半静态UCI的PUCCH资源中确定一个PUCCH资源作为所述第一PUCCH资源。
其中，需要进行载波切换的PUCCH具有对应的PDCCH，也就是说需要进行载波切换的PUCCH承载的是动态UCI或者说需要在第一PUCCH资源上传输的UCI是动态UCI，动态UCI例如HARQ-ACK，且HARQ-ACK为具有PDCCH调度的PDSCH或指示SPS PDSCH资源释放的PDCCH或指示Scell Dormancy的PDCCH的HARQ-ACK或DCI触发的type3码本的HARQ-ACK。
其中，需要进行载波切换的PUCCH没有对应的PDCCH，也就是说需要进行载波切换的PUCCH承载的是半静态UCI或者说需要在第一PUCCH资源上传输的UCI是半静态UCI，半静态UCI例如SPS HARQ-ACK(即SPS PDSCH的HARQ-ACK)，CSI(周期CSI或SP-CSI)，SR等。该实施例中，在第二载波上为每种半静态UCI预先配置了对应的PUCCH资源，故，在第 二载波上预先配置的对应半静态UCI的PUCCH资源中确定一个PUCCH资源作为所述第一PUCCH资源具体为：根据需要进行载波切换的PUCCH上承载的UCI类型，来确定该第一PUCCH资源，如果在第二载波上预先为同一种UCI类型配置了多个PUCCH资源，则可以根据这种UCI类型的比特数，在这种UCI类型对应的多个资源中选择一个PUCCH资源作为第一PUCCH资源。
即，确定第一PUCCH资源的方式2是：按照需要进行载波切换的PUCCH是否有对应的PDCCH或是承载UCI类型为动态还是半静态UCI，
若具有对应的PDCCH或承载的UCI类型为动态UCI，则进一步由需要进行载波切换的PUCCH对应的最后一个PDCCH中的PUCCH资源指示域，在第二载波上的预先配置的PUCCH资源集合(这里的资源集合是配置给具有对应的PDCCH的PUCCH传输使用的资源集合，可以是第二载波上专门配置给载波切换使用的，也可以是第二载波上其他用途的PUCCH资源)中确定一个PUCCH资源为第一PUCCH资源；
若没有对应的PDCCH或承载的UCI类型是半静态UCI，则进一步在第二载波上预先配置的对应半静态UCI的PUCCH资源(这里的资源可以是第二载波上专门配置的用于PUCCH载波切换时使用的资源，也可以是第二载波上其他用途的PUCCH资源)中确定一个PUCCH资源作为第一PUCCH资源。
而该预先配置的PUCCH资源集合可以为一个或多个PUCCH资源集合，当该预先配置的PUCCH资源集合为多个PUCCH资源集合时，不同的PUCCH资源集合对应承载不同的UCI比特数，则会先根据需要在该第一PUCCH资源上传输的UCI的比特数，在该多个PUCCH资源集合中选择一个候选资源集合；再根据上述的PUCCH资源指示域，在该候选资源集合中确定一个PUCCH资源作为第一PUCCH资源。
该实施例中，需要在所述第一PUCCH资源上传输的UCI可以是需要进行PUCCH载波切换的PUCCH中原本承载的UCI的全部或者部分信息(也即可能规定在进行PUCCH载波切换时，可以丢弃切换之前的PUCCH上的部分UCI，例如CSI，仅将部分UCI切换到新的载波上通过PUCCH传输，例 如HARQ-ACK)。需要进行PUCCH载波切换的PUCCH也即原本应该在第一载波上传输的PUCCH，但根据PUCCH载波切换规则，确定需要切换到第二载波上进行传输。
该实施例中，可选地，所述按照预定方式确定PUCCH载波切换后在第二载波上的第一PUCCH资源，包括：
将所述第二载波上的第三PUCCH资源作为所述第一PUCCH资源；
其中，所述第三PUCCH资源为第二载波上预先配置的一个PUCCH资源，所述第三PUCCH资源为第一类PUCCH资源，所述第一类PUCCH资源包括以下至少一项：
对应第一类预设PUCCH格式的PUCCH资源；
承载容量大于预设门限的PUCCH资源。
即，确定第一PUCCH资源的方式3是：将在第二载波上预先配置的一个PUCCH资源作为所述第一PUCCH资源。这里该预先配置的一个PUCCH资源可以是第二载波上专门配置的用于PUCCH载波切换时使用的资源，也可以是第二载波上其他用途的PUCCH资源。
其中，第一类预设PUCCH格式包括：PUCCH格式2、3和4。预设门限可以为2比特。即，第三PUCCH资源为第一类PUCCH资源，也就是承载容量大的PUCCH资源，从而可以通过这一个第三PUCCH资源兼顾需要进行载波切换的PUCCH上承载的任何UCI比特数。这个PUCCH资源可以给任何UCI(动态或半静态)、任何比特数传输使用。为了兼顾大比特和小比特的统一可以使用这个资源传输，这个资源的承载容量需足够大，比如配置的RB资源比较多，从而可以支持使用一个PUCCH资源支持对1-2比特、2比特以上等任何比特数的UCI的传输，比如可以支持1比特或2比特传输，也可以支持3比特传输，甚至是100比特传输。为了降低传输开销，使用这个PUCCH资源传输时，可以根据PUCCH承载的UCI比特确定这个PUCCH资源实际占用的RB个数(RBmin)，按照实际占用的RB个数使用这个PUCCH资源进行传输，以降低资源开销。
这里，第二载波上预先配置的一个用于PUCCH载波切换传输的PUCCH资源，可以是针对每一个会进行PUCCH载波切换的终端配置，也就是说在 第二载波上是per-UE的配置这样的资源；也可以是在第二载波上配置载波专属的用于PUCCH载波切换传输的PUCCH资源，则这些PUCCH资源并不是专门针对某一个UE的，切换到第二载波上的任何UE都可以使用这些PUCCH资源，即这些PUCCH资源针对进行PUCCH载波切换的多个UE而言是共享的。
另外，该实施例中，所述方法还包括：如果需要在所述第一PUCCH资源上传输的UCI的比特数不足预定阈值，在UCI中补充信息直到达到所述预定阈值。
这样，对于PUCCH资源采用编码方式传输UCI，考虑到编码方式针对不小于预定阈值的UCI比特数进行，预定阈值可以是3比特，所以如果基于预先配置预定阈值，需要在第一PUCCH资源上传输的UCI的比特数不足该预定阈值，会在UCI中补充信息直到达到该预定阈值，从而使用编码方式传输UCI。
其中，UCI中补充信息可以是在UCI的尾部(或头部)增加比特。且，增加的比特可以是占位比特，或者重复UCI原本的信息比特等。
该实施例中，可选地，所述按照预定方式确定PUCCH载波切换后在第二载波上的第一PUCCH资源，包括：
根据需要在所述第一PUCCH资源上传输的UCI的比特数，在所述第二载波上预先配置的一个或多个PUCCH资源集合中确定一个PUCCH资源作为所述第一PUCCH资源；
其中，所述一个或多个PUCCH资源集合中包括以下至少一个第一类PUCCH资源以及至少一个第二类PUCCH资源，所述第一类PUCCH资源为承载容量大于预设门限的PUCCH资源或对应第一类预设PUCCH格式的资源，所述第二类PUCCH资源为承载容量不超过预设门限的PUCCH资源或对应第二类预设PUCCH格式的资源。
即确定第一PUCCH资源的方式4是：在第二载波上预先配置一个或多个PUCCH资源集合，该一个或多个PUCCH资源集合中包括了至少两类PUCCH资源(一类是承载容量大于预设门限的PUCCH资源或对应第一类预设PUCCH格式的资源，一类是承载容量不超过预设门限的PUCCH资源或对 应第二类预设PUCCH格式的资源)，由需要在该第一PUCCH资源上传输的UCI的比特数，在该一个或多个PUCCH资源集合(这里的一个或多个资源集合可以是第二载波上专门配置的用于PUCCH载波切换时使用的资源，也可以是第二载波上其他用途的PUCCH资源)中确定一个PUCCH资源作为所述第一PUCCH资源。
这里，第一类PUCCH资源由上可知为大容量PUCCH资源，而第二类PUCCH资源是承载容量不超过预设门限的PUCCH资源或对应第二类预设PUCCH格式的资源，第二类预设PUCCH格式包括：PUCCH格式0和1，即第二类PUCCH资源是小容量PUCCH资源。此时，配置的该一个或多个PUCCH资源集合兼顾大比特和小比特的传输。
第二载波上预先配置的一个或多个PUCCH资源集合，可以是针对每一个会进行PUCCH载波切换的终端配置，也就是说在第二载波上是per-UE的配置这样的资源集合；也可以是在第二载波上配置载波专属的用于PUCCH载波切换传输的PUCCH资源集合，则这些PUCCH资源集合并不是专门针对某一个UE的，切换到第二载波上的任何UE都可以使用这些PUCCH资源集合，即这些PUCCH资源集合针对进行PUCCH载波切换的多个UE而言是共享的。
其中，该一个或多个PUCCH资源集合，可能从配置较少的资源数的角度，配置为仅包括一个第一类PUCCH资源和一个第二类PUCCH资源；可能从灵活以及处理时延的角度，配置为包括多个第一类PUCCH资源和/或多个第二类PUCCH资源。
因此，一方面，可选地，所述在所述第二载波上预先配置的一个或多个PUCCH资源集合中确定一个PUCCH资源作为所述第一PUCCH资源，包括：
当所述一个或多个PUCCH资源集合中仅包括一个第一类PUCCH资源和一个第二类PUCCH资源，则确定与需要进行载波切换的PUCCH上承载的UCI的比特数对应的PUCCH资源作为所述第一PUCCH资源。
这样，对应需要进行载波切换的PUCCH上承载的UCI的比特数，在这两个资源中选取适用的资源作为第一PUCCH资源。其中，这一个第二类PUCCH资源(小容量PUCCH(不超过2比特的))，可以总是按照2比特的 承载容量进行配置，如配置PUCCH格式0，相应的，确定该PUCCH格式0的资源为第一PUCCH资源时，传输HARQ-ACK时会占用4个循环移位，分别对应2比特HARQ-ACK的4个组合状态({ACK，ACK}，{NACK，NACK}，{ACK，NACK}，{NACK，ACK})，如果只有1比特UCI传输，则可以补位成2比特，比如补充1比特NACK，按照4个循环移位与2比特HARQ-ACK状态的对应关系，选择4个循环移位中的一个循环移位，使用选择的循环移位进行传输；也可以总是按照1比特的承载容量进行配置，相应的，确定该1比特的承载容量的资源为第一PUCCH资源时，如果需要传输2比特UCI，则2比特UCI进行合并得到1比特UCI再进行传输。其中，这一个第一类PUCCH资源(大容量PUCCH(大于2比特的))，可以配置比较大的容量，比如配置较多的RB，从而可以支持使用一个PUCCH资源支持对2比特以上的比较大范围的比特数的UCI的传输，比如3比特可以使用这个PUCCH资源传输，100比特也可以使用这个PUCCH资源传输，为了降低传输开销，使用这个PUCCH资源传输时，可以根据PUCCH承载的UCI比特确定这个PUCCH资源实际占用的RB个数(RBmin)，按照实际占用的RB个数使用这个PUCCH资源进行传输，以降低资源开销。
另一方面，可选地，所述在所述第二载波上预先配置的一个或多个PUCCH资源集合中确定一个PUCCH资源作为所述第一PUCCH资源，包括：
当所述一个或多个PUCCH资源集合中包括多个第一类PUCCH资源和/或多个第二类PUCCH资源，则根据需要在所述第一PUCCH资源上传输的UCI的比特数，在第一类PUCCH资源和第二类PUCCH资源中确定一类PUCCH资源；当所述确定的一类PUCCH资源中包含多个PUCCH资源时，在所述确定的一类PUCCH资源中，将第四PUCCH资源作为所述第一PUCCH资源；
其中，所述第四PUCCH资源的起始位置不早于第二PUCCH资源的起始位置；或者，所述第四PUCCH资源满足UCI传输的处理时间要求，所述第二PUCCH资源是进行载波切换的PUCCH在所述第一载波上对应的PUCCH资源。
这里，对于一个或多个PUCCH资源集合配置为包括多个第一类PUCCH 资源和/或多个第二类PUCCH资源，会先根据需要在所述第一PUCCH资源上传输的UCI的比特数，在大容量和小容量中选择一类(即在第一类PUCCH资源和第二类PUCCH资源中确定一类PUCCH资源)，然后在所确定的一类PUCCH资源的多个PUCCH资源中，选择起始位置不早于进行载波切换的PUCCH在所述第一载波上对应的PUCCH资源的，或者满足UCI传输的处理时间要求的PUCCH资源(即第四PUCCH资源)作为第一PUCCH资源。当然，第四PUCCH资源的起始位置不早于进行载波切换的PUCCH在所述第一载波上对应的PUCCH资源的情况下，该第四PUCCH资源在第二载波上确定传输PUCCH的时间单元中。
然而，考虑到第四PUCCH资源存在多个资源，可选地，所述将第四PUCCH资源作为所述第一PUCCH资源，包括：
若所述第四PUCCH资源包括多个PUCCH资源，则基于以下至少一项，在所述多个PUCCH资源中选择一个PUCCH资源作为所述第一PUCCH资源：
起始位置；
占用符号个数；
承载容量；
资源编号。
具体如基于上述任一项，在该多个PUCCH资源中选择起始符号最早的一个PUCCH资源、选择占用符号个数最少的一个、选择承载容量最小容量的一个、选择PUCCH资源编号最小的一个作为所述第一PUCCH资源。此时，选择所基于的一项信息总是可以选择出唯一的一个PUCCH资源即不存在多个PUCCH资源都满足这个选择规则，例如选择起始符号最早的一个，则基站配置保证多个资源的起始符号不同。
或者，基于多种组合，从传输时延的角度，选择起始符号最早的一个，或者选择占用符号个数最少的一个，如果多个PUCCH资源的起始符号或占用符号数相同，则选择承载容量最小的一个(从开销角度考虑)，如果容量也相同，选PUCCH资源编号最小的一个；类似的，不同选择规则前后调整顺序也是可以的。
其中，UCI传输的处理时间要求可以是，准备UCI传输所需要的时间， 包括处理下行传输的时间，例如，在PUCCH上传输的是HARQ-ACK时，需要在PUCCH上进行HARQ-ACK的下行传输(包括PDSCH、需要进行HARQ-ACK反馈的PDCCH，比如指示SPS资源释放的PDCCH，指示SCell dormancy的PDCCH)的结束位置与PUCCH的起始位置之间满足固定的时间间隔，所述时间间隔是PDSCH处理以及准备在PUCCH上传输HARQ-ACK所需要的时间，这个时间间隔即为UCI传输的处理时间要求，例如定义为T proc,1＝((N 1+d 1,1+d 1,2)(2048+144)·κ2 -μ)·T C，其中N 1是与需要进行HARQ-ACK反馈的PDSCH的处理能力相关的处理时间，根据参考μ在处理能力列表中选择一个数值，κ为LTE采用间隔与NR采样间隔之间的比值，μ为SCS的索引，参考μ是调度PDSCH的PDCCH、PDSCH本身、PUCCH本身等对应的μ的最小值，T C为NR采用间隔，d 1,1为不同上行信道上传输HARQ-ACK的处理时间偏移值，如果在PUCCH上传输d 1,1＝0，如果在PUSCH上传输d 1,1＝1，d 1,2为与PDSCH所占用的符号数有关的处理时间偏移。
可选地，所述方法还包括：
当确定的所述第一PUCCH资源为第一类PUCCH资源时，根据所述第一PUCCH资源承载的UCI的比特数确定所述第一PUCCH资源实际占用的资源块RB个数。
也就是说，如上述方式确定的第一PUCCH资源为大容量资源，还会由第一PUCCH资源承载的UCI的比特数确定所述第一PUCCH资源实际占用的资源块RB个数，从而降低实际传输的PUCCH资源开销。
该实施例中，应该了解的是，方式1可以适用于动态和半静态UCI，可以适用于显示(比如有明显的信令指示)或隐式(比如按照规定规则或高层信令配置)方式触发的PUCCH载波切换。方式3和方式4可以对动态和半静态UCI都适用。
该实施例中，还应该了解的是，预先配置可以是通过该高层信令配置。
下面结合附图说明具体场景下，本公开实施例的方法的应用：
场景一：第一载波为原本配置传输PUCCH的载波(例如PCell或PUCCH Scell或PScell等)，第二载波为PUCCH可以通过载波切换进行PUCCH传输的载波，第一载波和第二载波的SCS相同，第一载波和第二载波上PUCCH 都是按照时隙为时间单元进行传输的，即每个PUCCH的时域资源都是不会超过一个时隙的，即第一载波上的反馈定时的单位为时隙(即PUCCH传输时间单元的单位)，则可以根据PDCCH中的反馈定时指示域所指示的k1，以及PDCCH所调度的PDSCH传输所在的时隙m，确定PDSCH的HARQ-ACK反馈在时隙(m+k1)即时隙n中传输(具体地在时隙n中的传输资源，例如符号位置、RB资源等都可以根据PDCCH中的PUCCH资源指示域获得，不再赘述)；则当确定第一载波上需要在时隙n中进行PUCCH传输，且根据PUCCH载波切换的规则，确定第一载波的时隙n中需要进行PUCCH载波切换，且切换到第二载波上的时隙n中进行传输，则：
按照方式1，假设第一载波的时隙n中的PUCCH资源的起始符号为符号A，占用B个符号，则可以确定在第二载波上的时隙n中传输的PUCCH资源为时隙n中的起始符号为A，占用B个符号的一个PUCCH资源，如图2所示。此时，这个PUCCH资源在频域上占用的RB个数和位置与第一载波上的PUCCH资源对应的RB个数和位置相同，从而不需要任何的额外信令指示，就可以确定PUCCH载波切换之后，目标载波上传输PUCCH的资源。
按照方式2，可以根据第一载波上的PUCCH所对应的PDCCH(即调度PDSCH的PDCCH)中的PUCCH资源指示域，在第二载波上预先配置的PUCCH资源集合中确定出一个PUCCH资源，则这个PUCCH资源的时域位置和频域RB以及可能使用的码域信息(循环移位，正交序列)等都可以是独立于第一载波上的PUCCH资源的，可以是不同于第一载波上的PUCCH资源的，如图3所示。
按照方式3，假设第二载波上仅配置了一个大容量PUCCH资源，例如PUCCH格式3，占用N个RB，则不论是第一载波上的任何PUCCH切换到第二载波上传输，都会使用这个资源，因此第二载波上传输切换的PUCCH的PUCCH资源的时域位置是固定的，而频域上占用的实际RB数，可以根据切换过来传输的UCI的比特数以及这个第二载波上的PUCCH资源的一些传输参数，比如码率、时域符号数、DMRS位置、正交序列、调制阶数等影响承载容量的参数，计算得到传输这些UCI比特数实际需要的最小RB个数RBmin。例如满足如下公式的
Figure PCTCN2022085804-appb-000001
数值即为最小的RB数，其中，r为码率， Q m为调制阶数，
Figure PCTCN2022085804-appb-000002
为PUCCH占用的符号中传输UCI的符号数(即除去DMRS占用的符号之外的符号)，
Figure PCTCN2022085804-appb-000003
为一个RB包含的子载波个数，O CRC为编码所添加的CRC比特数，O ACK为PUCCH承载的HARQ-ACK比特数(如果是其他UCI，则为其他UCI的比特数)，
Figure PCTCN2022085804-appb-000004
如图4所示。
按照方式4，假设第二载波上配置了2个PUCCH资源，一个为大容量PUCCH资源，例如PUCCH格式3，占用N个RB，一个为小容量PUCCH资源，例如PUCCH格式0；则根据第一载波上切换到第二载波上传输的PUCCH所承载的UCI的比特数，在第二载波上配置的2个PUCCH资源中选择一个，例如确定UCI比特数不超过2比特，则选择小容量PUCCH资源，又例如确定UCI比特数超过2比特，则选择大容量PUCCH资源，并按照上述方式3相同的方式确定实际占用的RBmin。示例图类似图4，不同的就是这个资源是从多个资源中选择出的。
在该场景中，终端和基站侧采用上述相同的方式确定第二载波上的传输切换PUCCH的时间单元中的PUCCH资源，终端侧在确定的PUCCH资源上发送PUCCH，基站侧在确定的PUCCH资源上接收PUCCH。
当然，PUCCH承载的HARQ-ACK替换为承载SPS PDSCH的HARQ-ACK或CSI或SR同样适用，所不同的是，第一载波上的PUCCH资源是按照承载SPS PDSCH的HARQ-ACK或CSI或SR的PUCCH资源获取方式确定的，从而得到第一载波上的PUCCH资源的起始符号和占用的符号个数，然后映射到第二载波上对应的时隙中对应的符号上传输。
此外，如果将第一载波的PUCCH传输时间单元改为长度为7个符号的子时隙，则第一载波上的反馈定时k1的单位也是子时隙，按照反馈定时确定在第一载波的子时隙(m+k1)即子时隙2n中进行PUCCH传输，且根据PUCCH载波切换的规则，确定第一载波的子时隙2n中需要进行PUCCH载波切换，且切换到第二载波上的时隙n中进行传输，则具体的处理方式同上，不再赘述，所不同的就是上述各图中第一载波上的时隙都替换为子时隙，例如图5所示。
场景二、基于场景一，如果第一载波和第二载波的SCS不同，例如第一 载波的SCS为15kHz，第二载波的SCS为30kHz，以两个载波上的时间单元的单位都是时隙为例，按照反馈定时确定在第一载波的时隙(m+k1)即时隙n中进行PUCCH传输，且根据PUCCH载波切换的规则，确定第一载波的时隙n中需要进行PUCCH载波切换，且切换到第二载波上的时隙2n中进行传输，则：
按照方式1，假设第一载波的时隙n中的PUCCH资源的起始符号为符号A，占用B个符号，则可以确定在第二载波上的时隙2n中传输的PUCCH资源为时隙2n中的起始符号为A，占用B个符号的一个PUCCH资源。此时，虽然起始符号的编号以及占用的符号个数都相同，但因为两个载波的SCS不同，导致两个载波上的一个符号的时间长度是不同的，即第一载波上的一个符号对应了第二载波上2个符号的时间长度，则按照相同的起始符号和占用符号个数，在第二载波上确定的PUCCH资源在时域上的传输长度是第一载波上的PUCCH资源的一半，如图6所示。这个PUCCH资源在频域上占用的RB个数和位置与第一载波上的PUCCH资源对应的RB个数和位置相同，从而不需要任何的额外信令指示，就可以确定PUCCH载波切换之后，目标载波上传输PUCCH的资源。
按照方式2，可以根据第一载波上的PUCCH所对应的PDCCH(即调度PDSCH的PDCCH)中的PUCCH资源指示域，在第二载波上预先配置的PUCCH资源集合中确定出一个PUCCH资源，则这个PUCCH资源的时域位置和频域RB以及可能使用的码域信息(循环移位，正交序列)等都可以是独立于第一载波上的PUCCH资源的，可以是不同于第一载波上的PUCCH资源的，如图7所示。
按照方式3，假设第二载波上仅配置了一个大容量PUCCH资源，例如PUCCH格式3，占用N个RB，则不论是第一载波上的任何PUCCH切换到第二载波上传输，都会使用这个资源，因此第二载波上传输切换的PUCCH的PUCCH资源的时域位置是固定的，而频域上占用的实际RB数，可以类似场景一实施例中的方式得到，如图8所示。
按照方式4，假设第二载波上配置了2个PUCCH资源，一个为大容量PUCCH资源，例如PUCCH格式3，占用N个RB，一个为小容量PUCCH 资源，例如PUCCH格式0；则根据第一载波上切换到第二载波上传输的PUCCH所承载的UCI的比特数，在第二载波上配置的2个PUCCH资源中选择一个，例如确定UCI比特数不超过2比特，则选择小容量PUCCH资源，又例如确定UCI比特数超过2比特，则选择大容量PUCCH资源，并按照上述方式3相同的方式确定实际占用的RBmin。示例图类似图8，不同的就是这个资源是从多个资源中选择出的。
该场景二中，终端和基站侧采用上述相同的方式确定第二载波上的传输切换PUCCH的时间单元中的PUCCH资源，终端侧在确定的PUCCH资源上发送PUCCH，基站侧在确定的PUCCH资源上接收PUCCH。
上述实施例中，改变第一载波和第二载波的SCS组合情况，也同样适用，在此不再赘述。
需要说明的，该实施例中以时隙或子时隙作为时间单元仅为举例，任何一个载波上改变时间单元为时隙或子时隙中的一种，或两个载波上分别是不同符号个数的子时隙，比如一个是2个符号的子时隙，一个是7个符号的子时隙，具体执行方式类似，不再赘述。该实施例中以PUCCH承载具有PDCCH调度的PDSCH的HARQ-ACK也仅为举例，将调度PDCCH的PDSCH替换为需要进行HARQ-ACK的PDCCH的情况类似，所不同的是此时HARQ-ACK可以是PDCCH本身的HARQ-ACK，且当PUCCH承载其他UCI时的情况也是类似，所不同的可能是对于CSI和/或SR，在第一载波上的PUCCH传输所在的第一时间单元以及其中的具体资源是根据高层信令配置确定的，并不是基于PDCCH通知的。
综上，本公开实施例的载波切换的传输处理方法，在需要进行PUCCH载波切换时，按照预定方式，确定切换后的载波上的PUCCH资源，从而在不需要额外信令通知或指示的基础上，确定出在切换后的载波上传输PUCCH的PUCCH资源，保证PUCCH载波切换传输的正常实现，同时不增加额外信令开销。
