可选地，目标小区(cell)可以包括但不限于主小区Pcell、主辅小区PScell和/或用于PUCCH的辅小区Scell等。网络侧设备可以基于实际情况，通过时域pattern为终端配置目标cell。
步骤23：终端在目标cell上进行PUCCH传输。
需指出的，本实施例优选在一个时刻只有一个PUCCH传输。本实施例适应的场景包括但不限于单载波、双连接、载波聚合等场景。
本申请实施例的上行传输方法，终端获取时域pattern之后，可以按照该时域pattern，确定目标cell，并在目标cell上进行PUCCH传输。由此，借助时域pattern，可以使得网络侧设备灵活地配置用于PUCCH传输的目标cell，从而减少PUCCH传输时延，进而提升PUCCH传输的可靠性。
一些实施例中，终端的PUCCH传输是用于承载混合自动重传请求确认(Hybrid Automatic Repeat reQuest-Acknowledge，HARQ-ACK)信息，以进行HARQ-ACK反馈。由此，借助本申请中的方案，可以减少HARQ-ACK反馈的时延，从而有利于低延时业务的传输。
一些实施例中，网络侧设备可以为UE配置一个或多个目标cell，此目标cell不限于是Pcell、PScell或PUCCH Scell等。网络侧设备可以为UE配置时域pattern，用于指示UE进行PUCCH传输的目标cell。
值得注意的是，网络侧设备可以在目标cell上都配置PUCCH资源。该PUCCH资源可以是每个cell独立配置的，也可以是目标cell与同一小区组内的其他cell采用相同的PUCCH配置，此其他cell比如为Pcell、PScell和/或PUCCH SCell等。
一种实施方式中，PUCCH资源是每个cell独立配置的，比如下表1所示， Pcell、PScell和/或PUCCH Scell上的PUCCH配置与目标cell上的PUCCH配置是独立配置的，注意，表1的目标cell表示除Pcell、PScell和PUCCH Scell之外的其他cell。

另一种实施方式中，PUCCH资源是所有cell相同配置的，比如下表2所示，Pcell、PScell和/或PUCCH Scell上的PUCCH配置与目标cell上的PUCCH配置是相同配置的，注意，表2的目标cell表示除Pcell、PScell和PUCCH Scell之外的其他cell。
表2
Figure PCTCN2022108265-appb-000002
可选地，上述时域pattern的配置参数可以包括目标cell的以下至少一项：
cell索引(index)；
小区pattern，所述小区pattern指示对应小区的上行时隙的位置；
起始位置；比如，目标cell的起始位置可以包括但不限于起始无线帧、起始子帧、起始时隙(slot)或者起始符号等；
持续时间；
小区配置周期；
子载波间隔；比如，该子载波间隔为15kHz或30kHz等；
时域粒度；比如，该时域粒度为slot粒度或者子时隙(sub-slot)粒度等。
一种目标cell的时域pattern配置方式中，时域pattern可以包括目标cell的如下参数：{cell index，cell pattern，起始位置，小区配置周期，子载波间隔，时域粒度}。
另一种目标cell的时域pattern配置方式中，时域pattern可以包括目标cell的如下参数：{cell index，小区配置周期，cell pattern(cell1,cell 2,…,cell n)，持续时间，子载波间隔，起始位置，时域粒度}。其中，cell pattern(cell1,cell 2,…,cell n)表示时域pattern中n个cell的cell顺序。持续时间为每个cell在cell pattern上的持续时间长度。
一些实施例中，如果网络侧设备为终端配置的时域pattern包括目标cell的index，则终端可以根据该index直接确定对应的目标cell。
一些实施例中，网络侧设备在为终端配置目标cell时，可以保证某一时刻在时域pattern上的上行UL资源只对应一个目标cell。
一些实施例中，如果网络侧设备在一个时刻配置了多个目标cell，则终端可以按照预定义的规则或高层参数确定一个目标cell。比如，该预定义的规则为选择具有最小或最大的cell index的目标cell。此外，终端也可以按照高层参数确定目标cell，比如按照时域粒度确定目标cell。
可选地，当按照时域pattern确定的终端在一个时刻比如当前时刻的目标cell具有多个时，终端可根据预定义的规则，从多个目标cell确定一个目标cell。比如，该预定义的规则为选择具有最小或最大的cell index的目标cell。此外，终端也可以按照高层参数确定目标cell，比如按照时域粒度确定目标cell。
可选地，目标cell的小区pattern的构成方式包括以下任意一种：第一小区pattern方式、第二小区pattern方式、第三小区pattern方式。其中，第一小区pattern方式为：由至少一个子pattern构成；第二小区pattern方式为：由时隙配置集合指示得到；第三小区pattern方式为：由cell集合构成。
可选地，每个子pattern可以包括以下至少一项：
子pattern周期P；比如，该子pattern周期P表征的是slot数；
下行(Downlink，DL)时隙的个数，该DL时隙包括的符号全是DL符号；
灵活时隙中的下行符号的个数；
上行(Uplink，UL)时隙的个数，该UL时隙包括的符号全是UL符号；
灵活时隙中的上行符号的个数。
可选地，在第一小区pattern方式下，小区pattern的周期由至少一个子pattern的周期确定。例如，如果小区pattern由2个子pattern构成，则小区pattern的周期由该2个子pattern的周期确定，比如，小区pattern的周期为该2个子pattern的周期之和。
可选地，上述用于指示第二小区pattern的时隙配置集合可以包括以下至少一项：
时隙集合；
时隙集合中的每个时隙的索引；
时隙集合中的每个时隙的符号集。
进一步的，每个时隙的符号集的配置可以满足以下任意一项：
符号集中的符号全是下行符号；
符号集中的符号全是上行符号；
符号集中的部分符号为下行符号，和符号集中的部分符号为上行符号。
可选地，在第二小区pattern方式下，小区pattern的周期可以由时隙配置集合的时隙集合中的时隙的个数确定。比如，如果时隙集合中的时隙的个数为5，则小区pattern的周期为5slot。
可选地，第三小区pattern方式为由cell集合构成，表示时域pattern中目标cell的顺序。例如{cell2，cell3，cell1}表示时域pattern中目标cell的顺序为cell2，cell3，cell1。此时，时域pattern的周期需要单独配置。同时每个目标cell的持续时间需要单独配置。
本申请实施例中，时域pattern可以由网络侧设备为终端配置。上述获取时域pattern可以包括：
终端从网络侧设备接收配置信息，其中，该配置信息用于指示为终端配置的时域pattern。这样，终端在接收到配置信息之后，即可根据配置信息确定为其配置的时域pattern。
可选地，上述配置信息可以用于指示：为终端配置的至少一个目标cell，以及每个目标cell的小区pattern；和/或，上述配置信息可以用于指示：为终端配置的至少一个目标cell，以及至少一个目标cell的小区pattern。
可选地，在本申请实施例中，终端还可以从网络侧设备接收指示信息，该指示信息用于指示为终端分配的PUCCH资源以及所述PUCCH资源所在的slot。之后，终端可以根据该slot以及配置信息指示的时域pattern，确定目标cell，并在目标cell的该PUCCH资源进行反馈。
可选地，在本申请实施例中，当终端的PUCCH传输为时隙粒度时，终端可以按照时域pattern选择配置为时隙粒度的目标cell；和/或，当终端的PUCCH传输为子时隙粒度时，终端可以按照时域pattern，选择配置为子时隙粒度的目标cell。
下面结合图3至图12对本申请具体实例进行说明。
实例1
本实例1中，网络侧设备为UE配置一个目标cell，该目标cell不限于是Pcell、PScell或PUCCH Scell等，并配置该目标cell的子载波间隔及cell pattern，该cell pattern由多个子pattern构成。例如，该cell pattern由1个子pattern构成，该1个子pattern为pattern1；或者，该cell pattern由2个子pattern构成，该2个子pattern为子pattern1和子pattern2。
其中，如图3所示，子pattern 1包含：
子pattern周期P1(表征为slot数)；
包括的符号全是DL符号的slot数，即DL slot数；
灵活时隙中的DL符号的个数；
包括的符号全是UL符号的slot数，即UL slot数；
灵活时隙中的UL符号的个数。
其中，灵活时隙的个数为：周期P1对应的slot数减少DL slot数，再减去UL slot数所得到的值。
可选地，灵活时隙/符号是否允许传输PUCCH可以由网络配置或按预定义规则确定。
其中，如图3所示，子pattern 2包含：
子pattern周期P2(表征为slot数)；
包括的符号全是DL符号的slot数；
灵活时隙中的DL符号的个数；
包括的符号全是UL符号的slot数；
灵活时隙中的UL符号的个数。
可选地，如果只配置了1个子pattern比如子pattern 1，则cell pattern的周期为子pattern1的周期，即P1。或者，如果只配置了2个子pattern比如子pattern 1和子pattern2，则cell pattern的周期为子pattern1和和子pattern2的周期之后，即P1与P2之和。
例如，参见图4所示，目标小区索引为CC1和CC2，CC1的cell pattern为DDDDD DDDUU，D表示下行时隙，U表示上行时隙，CC2的cell pattern为DDDUU DDDDD。时域pattern为cell pattern的UL资源取并集。其他时隙资源为DL构成，其不可用于UL PUCCH资源。因此，时域pattern为DDDUUDDDUU，子载波间隔是15kHz，CC1(如Pcell)上slot 8和slot 9可用于传输PUCCH，CC2上slot 3和slot 4可用于PUCCH传输，则：如果网络侧设备指示UE在slot 3或slot 4传输PUCCH，那么UE将使用CC2；或者，如果网络侧设备指示UE在slot 8或slot 9传输PUCCH，那么UE将使用CC1。这样，由于CC1和CC2是不同的分量载波(Component Carrier，CC)，通过这种时域pattern的配置可以达到PUCCH的载波切换。
进一步的，图4所示的时隙图中，可用于PUCCH传输的时隙为CC1上的slot 8和slot 9以及CC2的slot 3和slot 4。
进一步的，网络可以配置15kHz的子载波间隔，配置CC2为可用于传输 PUCCH的目标cell，CC2的cell pattern由2个子pattern构成，如下表3所示：
表3
Figure PCTCN2022108265-appb-000003
这样，通过两个子pattern即pattern1和pattern2的配置，可以确定目标cell(CC2)上可用的PUCCH传输的可用时隙或符号，即CC2上slot 3和slot 4可用于传输PUCCH。
另一种配置方式中，网络可以配置Pcell(PScell或PUCCH Scell)的资源总是可用于传输PUCCH，那么，cell pattern可以不包含Pcell(PSCell或PUCCH SCell)的指示。如图5所示，CC1为Pcell(PScell或PUCCH Scell)，则只配置CC2的cell pattern，该cell pattern由pattern1和pattern2构成。
当然，图5所示的cell pattern的起始位置也需要配置，例如起始无线帧位置、起始子帧位置、起始时隙位置或/或起始符号位置等。一个简单的配置为与Pcell的时分双工(Time Division Duplexing，TDD)的UL-DL配置对齐。一种可选方式中，cell pattern的起始位置与Pcell的无线帧0的子帧0的slot 0对齐。
实例2
本实例2中，网络侧设备为UE配置一个目标cell，该目标cell不限于是Pcell、PScell或PUCCH Scell等，并配置该目标cell的子载波间隔及cell pattern，该cell pattern由时隙配置集合指示。
其中，时隙配置集合包括：
1)时隙集合；
2)时隙集合中的每个时隙的索引；
3)时隙集合中的每个时隙的符号集。
进一步的，每个时隙的符号集可以配置为：全下行符号数，全上行符号数，或者，显式指示符号的传输方向即符号集中的部分符号为下行符号和部分符号为上行符号。
其中，cell pattern的周期由时隙集合中包含的时隙数确定。例如，时隙集合中有m个slot，那么cell pattern的周期m个slot。
其中，对于显式指示符号的传输方向，其中灵活符号数为：一个slot的符号数减去DL符号数后再减去UL符号数所得到的值。灵活符号是否允许传输PUCCH可由网络配置或按预定义规则确定。
实例3
本实例3中，网络可以同时配置多个目标CC及每个目标CC的cell pattern。当配置载波聚合时，由于UL-DL配置的不同，如果只配置一个cell pattern并不能完全降低PUCCH传输时延，因此，可以通过配置多个cell pattern进一步降低PUCCH传输时延。
例如，如图6所示，网络可以配置3个目标CC，其中，CC1的UL-DL配比为7D1S2U，该CC的小区图样(cell pattern)为DDDDD DDDUU，CC2的cell pattern1为DSUDDDSUDD，CC3的cell pattern2为DDSUU DDDSD，CC1、CC2和CC3的时域pattern为DDUUU DDUUU，即由不同目标cell的UL资源取并集，其他时隙视为DL。
此情况下，网络可以配置{目标cell index，cell pattern}组合的集合，用于指示多个目标cell上的候选PUCCH传输资源。
例如，参见下表4所示，网络可以为UE配置{目标cell index，cell pattern方式A，slot粒度，子载波间隔}。
表4
Figure PCTCN2022108265-appb-000004
Figure PCTCN2022108265-appb-000005
又例如，参见下表5所示，网络可以为UE配置{目标cell index，cell pattern方式B，slot粒度，子载波间隔}。
表5
Figure PCTCN2022108265-appb-000006
又例如，参见下表6所示，网络可以为UE配置{目标cell index，cell pattern方式A或B，slot粒度，子载波间隔}。
表6
Figure PCTCN2022108265-appb-000007
例如，针对图5所示的时隙图，可以利用下表7进行配置。
表7
Figure PCTCN2022108265-appb-000008
需指出的，表7所示的配置是用于候选PUCCH传输的参考配置，不是实际的UL-DL配置。
实例4
本实例4中，网络可以配置多个目标cell及一个cell pattern，该cell pattern应用于所有目标cell。比如，参见图7所示，可以为CC1、CC2和CC3配置一个cell pattern即DDUUU DDUUU，值得指出的是，这种情况下，CC1、CC2和CC3的cell pattern即为时域pattern。其中，CC1上slot 8和slot 9可用于传输PUCCH，CC2上slot 2和slot 7可用于PUCCH传输，CC3上slot 3、slot 4和slot 9可用于PUCCH传输。
可选地，网络可以保证某一时刻该cell pattern的UL资源只对应一个目标cell。如果某一个时刻对应多个目标cell，那么，UE可以按照预定义的规则或高层参数确定一个目标Cell，预定义的规则可以是具有最大的cell index的目标Cell。
可选地，网络可以为UE动态指示一个PUCCH资源的时隙，由UE根据该PUCCH资源的时隙以及cell pattern确定一个目标cell。比如，网络为UE指示的PUCCH资源的时隙是slot 4，则结合图6所示的cell pattern，由于CC3的slot 4是UL资源，则选择CC3。
实例5
本实例5中，应用于目标cell的cell pattern上的有效UL符号，可以是该目标cell的配置参数比如tdd-UL-DL-ConfigurationCommon和tdd-UL-DL-ConfigurationDedicated配置的可用的UL资源的子集。
例如，参见图8所示，应用于CC2和CC3的cell pattern上的有效UL符 号，可以是该CC2和CC3的tdd-UL-DL-ConfigurationCommon和tdd-UL-DL-ConfigurationDedicated配置的可用的UL资源的子集。其中，CC2上slot 2和slot 7可用于PUCCH传输，CC3上slot 3、slot 4和slot 9可用于PUCCH传输。
实例6
本实例6中，网络可以配置目标cell上的cell pattern是slot粒度或者sub-slot粒度。例如，当配置2个目标cell时，其中一个cell的cell pattern可以是slot粒度，另一个cell pattern是sub-slot粒度。
例如，参见图9所示，可以配置CC1和CC2的cell pattern是slot粒度，配置CC3的cell pattern是sub-slot粒度。如果在时刻1需要反馈的的HARQ-ACK码本codebook的粒度是slot，那么UE基于配置的cell pattern，可以选择CC1或CC2进行HARQ-ACK反馈。或者，如果在时刻2需要反馈的HARQ-ACK codebook的粒度是sub-slot，那么UE基于配置的cell pattern，可以选择CC3进行HARQ-ACK反馈。
实例7
本实例7中，网络为UE配置的cell pattern构成方式为第三小区pattern方式。网络可以为UE配置3个目标cell即CC1、CC2和CC3，相应UL-DL配置如图10所示。假设网络为UE配置的时域pattern的周期为40ms，子载波间隔为15kHz，cell pattern为{cell2，cell3，cell1}；t1时刻的目标cell为cell2，持续时间为10ms。t2时刻的目标cell为cell3，持续时间为10ms。t3时刻的目标cell为cell1，持续时间为20ms。这样，如图11所示，在t1-t2时间，时域pattern为cell2的UL-DL配置，UE将使用cell2的UL资源进行PUCCH反馈；在t2-t3时间，时域pattern为cell3的UL-DL配置，UE将使用cell3的UL资源进行PUCCH反馈；在t3-t4时间，时域pattern为cell1的UL-DL配置，UE将使用cell 1的UL资源进行PUCCH反馈。
可选地，网络配置的时域pattern的周期可以大于配置的cell pattern的周期，如图12所示，其中，配置的cell pattern为{cell2，cell3}，持续时间{10ms， 10ms}。对于一个时域pattern的周期内未进行cell pattern配置的时间，可以按预定义或配置的cell作为目标cell，例如Pcell。
可选地，在一个cell group内，网络可以配置一个时域pattern，该时域pattern应用于整个cell group。
可选地，网络也可以为每个目标cell配置时域pattern。
可选地，网络可以配置每个目标cell是基于slot粒度还是sub-slot粒度。
一种可选实施方式中，时域pattern的配置周期可以是无线帧对齐。
可选地，目标cell的持续时间应该与相应UL-DL配置的周期一致。例如，cell2的UL-DL配置的10个slot的传输方向分别为DSUDD DSUDD，S表示特殊时隙，子载波间隔为15kHz，则：如果配置的持续时间为9ms，那么cell2的相应slot的传输方向分别为是DSUDD DSUD；或者，如果配置的持续时间为14ms，那么cell2的相应slot的传输方向是DSUDD DSUDD DSUD。
又例如，对于cell2，如果配置的子载波间隔为30KHz，持续时间为10ms，那么需要根据子载波间隔进行折算，即相当于2个子帧，相应slot的传输方向为：DSUDD DSUDD DSUDD DSUDD。
