具体实施方式
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描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统应用以外的应用，如第6 代(6th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11也可以称作终端设备或者用户终端，终端11可以是手机、平板电脑(Tablet Personal Computer，TPC)、膝上型电脑(Laptop Computer，LC)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、机器人、可穿戴式设备(Wearable Device，WD)或车载设备(Vehicle User Equipment，VUE)、行人终端(Pedestrian User Equipment，PUE)、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)等终端侧设备，可穿戴式设备包括：智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装、游戏机等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网设备，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、无线局域网络(Wireless Local Area Networks，WLAN)接入点、无线保真(Wireless Fidelity，WiFi)节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
与以往的移动通信系统相比，第5代(5th Generation，5G)移动通信系统需要适应更加多样化的场景和业务需求。NR的主要场景包括移动宽带增强(eMBB)、大规模物联网(mMTC)、超高可靠超低时延通信(Ultra-Reliable and Low Latency Communications，URLLC)，这些场景对系统提出了高可靠、低时延、大带宽、广覆盖等要求。
这些不同的业务有不同的服务质量(QoS)的要求，例如URLLC支持低 时延、高可靠业务。为了达到更高的可靠性，需要使用更低的码率传输数据，同时需要更快、更精确的信道状态信息(Channel State Information，CSI)的反馈。eMBB业务支持高吞吐量的要求，但是对于时延和可靠性不如URLLC那么敏感。另外对于某些UE可能支持不同数值配置(numerology)的业务，UE既支持URLLC低时延高可靠业务，同时支持大容量高速率的eMBB业务。
相关技术中，基站可以通过无线资源控制(Radio Resource Control，RRC)信令为每个UE配置一个或多个(最多4个)PUCCH(物理上行控制信道)资源集(PUCCH resource set)，RRC配置或预定义每个资源集(Resource Set，RESET)可以承载的上行控制信息(Uplink Control Information，UCI)有效载荷(payload)的最大比特数(例如第一个RESET最多2bit，第2第3个RESET为N1,N2,第4个RESET最多为1706bit，N1，N2是RRC配置),每个RESET内可以包含多个PUCCH resource(第一个RESET内最多32个PUCCH resource，其他RESET每个最多包含8个PUCCH resource)。在UE侧，UE接收到物理下行共享信道(Physical Downlink Shared Channel，PDSCH)和某些物理下行控制信道(Physical Downlink Control Channel，PDCCH)后需要反馈混合自动重传请求-确认(Hybrid automatic repeat request acknowledgement，HARQ-ACK)，为了确定反馈HARQ-ACK所在PUCCH资源，UE需要先通过调度PDSCH的PDCCH中的K1(PDSCH到HARQ-ACK反馈的定时指示)确定PUCCH所在时隙(slot)，然后通过需要反馈的HARQ-ACK的比特数确定PUCCH所在RESET，在所确定的RESET内，根据PDCCH的物理上行控制信道资源指示(PUCCH resource indicator，PRI)域(RESET内所含资源不超过8个时)或PRI+PDCCH第一个控制信道单元(Control Channel Element，CCE)的索引(first CCE index)确定具体是RESET内的哪一个PUCCH资源(RESET内所含资源超过8个时)。当有多个PDSCH的HARQ-ACK在一个slot反馈时，UE根据调度这些PDSCH的最后一个下行控制信息(last Downlink Control Information，last DCI)中的PRI和CCE index确定PUCCH资源。
相关技术中，为了降低峰值平均功率比(Peak-to-Average Power Ratio，PAPR),同一时间，UE只能传输一个PUCCH或者PUSCH,因此在一个 PUCCH组(PUCCH group)内，当PUCCH和PUCCH，或者PUCCH和PUSCH时域资源重叠时，UE需要解决PUCCH和PUCCH，或者PUCCH和PUSCH时域资源重叠问题，也可以说是PUCCH和PUCCH，或者PUCCH和PUSCH冲突问题。例如相同优先级时，将不同的PUCCH的UCI进行复用，或者将PUCCH承载的UCI复用在PUSCH上传输。不同优先级时，则取消低优先级的PUCCH/PUSCH的传输，只传输高优先级的PUCCH/PUSCH。
为了实现灵活的网络部署，NR系统中通过时隙格式(slot format)的方式配置一个时隙中各个符号的传输方向。
NR中时隙的传输方向有三种定义，下行(Downlink，DL)、上行(Uplink，UL)、灵活(flexible)。当网络配置了一个时隙或符号是DL或UL，则该时刻的传输方向是明确的；当网络配置了一个时隙或符号是flexible，则该时刻的传输方向是待定的。网络可以通过动态信令，如dynamic时隙格式指示来对flexible的时隙或符号的传输方向进行修改。
如图2所示，一个slot可以包含下行(downlink)，上行(uplink)和灵活(flexible)的正交频分复用(Orthogonal Frequency Division Multiplex，OFDM)符号；Flexible符号可以被改写为下行或者上行符号。
SFI可以指示一个或者多个slot的格式。SFI在组公共-物理下行控制信道(GC-PDCCH)中发送。
SFI可以灵活地根据需求改变半静态配置的slot的格式，以满足业务传输需求。
UE根据SFI的指示决定是否监测PDCCH。
基站可以通过高层参数UL-DL-configuration-common和UL-DL-configuration-common-Set2(可选的)半静态地给UE配置一个或者多个小区专属(cell-specific)的slot格式。
基站也可以通过高层参数UL-DL-configuration-dedicated半静态地UE配置一个或者多个UE专属(UE-specific)的slot格式。
基站可以通过GC-PDCCH中承载的SFI改写半静态配置中的flexible symbol或者slot。
由UE专属RRC配置隐式指示的传输方向被统称为测量(measurement)， 包括：
UE专属的RRC信令配置的周期性或者半持续的信道状态信息-参考信号(CSI-RS)测量，周期性的CSI上报，周期性或者半持续的探测参考信号(Sounding Reference Signal，SRS)所隐式指示的上下行传输方向；
UE专属的RRC配置的物理随机接入信道(Physical Random Access Channel，PRACH)资源，type1和type2免授权上行传输；
对type2的免授权上行传输，只有第一个激活的资源上的传输被看做UE专属的数据(UE-specific data)。
UE-specific传输包括物理下行共享信道(Physical Downlink Shared Channel，PDCSH)，物理上行共享信道(Physical Uplink Control Channel，PUSCH)，PDSCH的A/N反馈，DCI触发的非周期测量等。
相关技术中，为了进一步降低上行控制信息传输的时延，引入了PUCCH carrier switching的特征，即PUCCH载波切换。在现有技术中，在一个PUCCH组内，PUCCH资源只能配置在一个cell上，即主小区(Pcell)或主辅小区(PScell)或PUCCH辅小区(SCell)上。PUCCH传输受到半静态配置或者动态指示的时隙格式的限制，例如PUCCH不能在配置为DL的符号上传输。因此当PUCCH资源被全部或部分配置在DL符号上，该PUCCH将不能传输，其承载的UCI也只能被丢弃。当UE支持PUCCH carrier switching时，在一个PUCCH组内，PUCCH资源可以配置在多于一个cell上，例如PUCCH资源配置在2个cell上。在某个时间，PUCCH在哪个cell上传输，可以基于一定的规则或者动态指示确定。
相关技术中PUCCH/PUSCH的传输受到SFI的限制(流程1，根据SFI确定PUCCH或PUSCH是否能够传输)，同时UE还需要进行UE内部的PUCCH和PUCCH或者PUCCH和PUSCH之间的冲突处理(流程2，PUCCH overriding/intra-UE mulitplexing/priortization)，具体的，先执行流程2，再执行流程1。相关技术还支持PUCCH carrier switching(流程3，确定PUCCH所在cell)。在这种场景下，UE应按照何种顺序进行上述三个流程需要讨论。
本申请实施例提供一种上行传输方法，由终端执行，如图3所示，所述方法包括：
确定第一PUCCH传输所在的小区；
若第一PUCCH与第二上行信道的时域资源重叠，根据半静态上下行配置信息和/或SFI确定是否传输所述第一PUCCH和/或所述第二上行信道，所述第二上行信道包括第二PUCCH和/或第二PUSCH。
在本申请实施例中，给出了当UE被配置PUCCH载波切换时执行步骤的顺序，能够提高通信系统的有效性。
一些实施例中，所述第二上行信道包括第二PUCCH，若所述第一PUCCH和所述第二PUCCH在同一小区上，复用所述第一PUCCH和所述第二PUCCH。
一些实施例中，第一PUCCH与第二上行信道的时域资源重叠包括以下至少一项：
同一小区上的第一PUCCH和第二PUCCH的时域资源重叠；
同一PUCCH组内不同小区上第一PUCCH与第二PUCCH的时域资源重叠。
一些实施例中，所述确定第一PUCCH所在的小区包括；
根据DCI的指示、预设规则、半静态上下行配置信息和SFI中的至少一项确定第一PUCCH传输所在的小区。
一些实施例中，所述确定第一PUCCH所在的小区具体包括以下任一项：
根据所述DCI中特定信息域的指示确定第一PUCCH传输所在的小区。可选地，特定信息域可以为上下行资源分配信息域、HARQ信息域或功率控制信息域等；或
根据半静态上下行配置信息和/或SFI确定PUCCH资源可用的小区。
一些实施例中，若确定PUCCH资源可用的小区的数目大于1，选择小区标识最大或最小的小区作为第一PUCCH所在的小区。
一些实施例中，根据最后一个DCI中信息域的指示确定第一PUCCH传输所在的小区。
一些实施例中，确定第一PUCCH传输所在的小区之后，所述方法还包括：
确定第一PUCCH的资源索引。
一些实施例中，确定第一PUCCH传输所在的小区之前，所述方法还包 括：
确定第一PUCCH的资源索引。
一些实施例中，在需要反馈HARQ-ACK时，确定第一PUCCH的资源索引。
一些实施例中，对于由不同DCI调度的PDSCH形成的HARQ-ACK码本，不期望所述不同DCI指示的PUCCH小区不同。
一些实施例中，若所述第一PUCCH和所述第二PUCCH在不同的小区上，且所述第一PUCCH所在的第一小区与所述第二PUCCH所在的第二小区具有不同的SCS，根据第三小区上的SCS确定第一PUCCH复用的时间单元，所述第三小区选自第一小区和第二小区。

根据DCI的指示确定的PUCCH所在的小区；
根据DCI指示的高优先级UCI所在PUCCH所在的小区；
高优先级UCI所在的小区；
小区标识最大的小区；

一具体实施方式中，如图4所示，是PUCCH resource overriding的过程。其中DCI 1调度UE在时隙n反馈HARQ-ACK，UE接收到DCI 1后根据该时隙需要反馈的HARQ-ACK的比特数和DCI 1中的PRI的指示，确定反馈HARQ-ACK的PUCCH，如PUCCH1。在DCI1之后，UE又接收到DCI2，同样调度UE在时隙n反馈HARQ-ACK，则UE需要将DCI1调度的PDSCH的HARQ-ACK与DCI2调度的PDSCH的HARQ-ACK进行合并反馈，因此，UE根据新的HARQ-ACK的比特数(+DCI2调度的PDSCH的HARQ-ACK)以及DCI2的PRI指示确定反馈HARQ-ACK的PUCCH，如PUCCH2.即UE根据接收到的DCI，不断更新一个时隙内反馈HARQ-ACK PUCCH资源的过程称为PUCCH overriding。
如图5所示，是半静态上行配置和/或SFI配置，其中每个符号可以被配置/指示为DL符号、灵活符号或者上行符号。PUCCH只能在上行和/或灵活符号上传输。其中PUCCH/PUSCH在传输前需要根据其所在符号的上下行配 置和或SFI指示，确定其是否能够传输，例如PUCCH在SFI指示的UL符号上，则PUCCH可以传输，如果PUCCH部分或全部符号为DL符号，则该PUCCH不能传输。
如图6所示，控制信道(Control Channel，CC)0和CC1上都配置了PUCCH资源。在某个时间单元，UE在哪个CC上传输PUCCH，可以根据一定的方式确定，例如根据DCI的指示，和/或者根据高层配置的PUCCH cell时间pattern(例如，根据PUCCH cell时间pattern配置可以确定，在该时隙，哪个CC上的PUCCH资源是可用的)或者根据其他方式确定。
另一具体实施方式中，当UE被配置了一个PUCCH组内的多个CC上有PUCCH资源，UE根据以下实施例确定PUCCH/PUSCH传输：
实施例一
本实施例包括以下步骤：
步骤(Step)1：确定PUCCH传输的cell，例如UE可以根据DCI的指示和/或者根据预设规则(例如PUCCH cell(resource)时间pattern)确定在某个时间单元内PUCCH传输所在的cell(不考虑半静态上下行配置或者SFI)，如确定PUCCH传输的cell为PUCCH cell 1；
Step 2：如果在某个时间单元有HARQ-ACK需要反馈，则执行PUCCH resource overriding程序，即根据last DCI的指示确定反馈HARQ-ACK的PUCCH resource；
可选的，对于由不同DCI调度的PDSCH形成的一个HARQ-ACK码本(例如同一时间单元反馈的同一个优先级的HARQ-ACK)，终端不期待DCI指示的PUCCH cell不同；
Step 3：如果有PUCCH和PUCCH或者PUCCH和PUSCH之间的时域资源重叠，则执行PUCCH和PUCCH和/或PUCCH和PUSCH之间的复用或者优先，包括以下任一项：
(1)只有当PUCCH在同一个cell上，才支持PUCCH和PUCCH的复用；
(2)上述PUCCH和PUCCH时域资源重叠包括同一cell上的PUCCH和PUCCH时域资源重叠，以及同一PUCCH组内不同cell上的时域资源重叠， 可选的，当重叠的PUCCH在不同的cell上时，如果不同cell具有不同的子载波间隔(SCS)，则根据cell 1上的SCS确定PUCCH复用/优先的时间单元，其中cell 1根据以下任一方式确定：
方式1：根据DCI指示确定PUCCH cell；
方式2：根据DCI指示确定的高优先级UCI所在PUCCH cell；
方式3：高优先级UCI所在cell；
方式4：cell index最大或最小的cell。
Step 4：根据半静态上下行配置和/或SFI确定step 3中确定的PUCCH、PUSCH是否可以传输。
实施例二
本实施例包括以下步骤：
Step 1：确定PUCCH传输的cell，例如UE可以根据DCI的指示、预设规则、半静态上下行配置和/或SFI确定在某个时间单元内PUCCH传输所在的cell，如确定PUCCH传输的cell为PUCCH cell 1；
例如DCI中包含信息域指示PUCCH所在cell，或者根据半静态上下行配置和/或SFI选择PUCCH资源可用的cell，如果多个cell上PUCCH资源都可用，则可以选择cell index最大或最小的。
Step 2：如果在某个时间单元有HARQ-ACK需要反馈，则执行PUCCH resource overriding程序，即根据last DCI的指示确定反馈HARQ-ACK的PUCCH resource；
Step 3：如果有PUCCH和PUCCH或者PUCCH和PUSCH之间的时域资源重叠，则执行PUCCH和PUCCH或则PUCCH和PUSCH之间的复用或者优先；
Step 4：根据半静态上行配置或者SFI确定step 3中确定的PUCCH、PUSCH是否可以传输。
实施例三
本实施例包括以下步骤：
Step 1：如果在某个时间单元有HARQ-ACK需要反馈，则执行PUCCH resource overriding程序，即根据last DCI的指示确定反馈HARQ-ACK的 PUCCH resource；
Step 2：确定PUCCH传输的cell，例如UE可以根据DCI的指示、预设规则、半静态上下行配置和/或SFI确定在某个时间单元内PUCCH传输所在的cell，如确定PUCCH传输的cell为PUCCH cell 1；
可选的，可以是根据last DCI的指示确定PUCCH所在cell；
Step 3：如果有PUCCH和PUCCH或者PUCCH和PUSCH之间的时域资源重叠，则执行PUCCH和PUCCH或则PUCCH和PUSCH之间的复用或者优先；
Step 4：根据半静态上行行配置和/或SFI确定step 3中确定的PUCCH、PUSCH是否可以传输。
另一具体实施方式中，可以根据DCI的指示确定PUCCH所在cell。其中DCI 1指示在时隙n反馈低优先级(Low Priority，LP)HARQ-ACK并指示其cell为cell 1，DCI 2指示在时隙n反馈LP HARQ-ACK。一种方式中，UE期待DCI 2指示的PUCCH所在cell为cell 1，否则为错误场景。另一种方式是，UE按照DCI 2的指示确定时隙n LP HARQ-ACK反馈所在的cell，例如如果DCI 2指示在cell 1上反馈HARQ-ACK，则UE在时隙n将在cell 1上反馈DCI 1和DCI 2对应的PDSCH的HARQ-ACK。如果DCI 2指示其cell为cell 1以外的cell，如cell 2，则UE在时隙n在cell 2上反馈HARQ-ACK，可选的，采用以下任一方式：
方式1：在时隙n，UE在cell 1上反馈DCI 1对应的PDSCH的HARQ-ACK，在cell2上反馈DCI 2对应的PDSCH的HARQ-ACK；
方式2：在时隙n，在cell2上反馈DCI1和DCI 2对应的PDSCH的HARQ-ACK；
方式3：在时隙n，在cell2上仅反馈DCI 2对应的PDSCH的HARQ-ACK，DCI 1对应的PDSCH的HARQ-ACK不反馈。
在另一个实施例中，如图7所示，DCI 1和DCI 2指示在相同的时间单元反馈HARQ-ACK，如时隙n。但其HARQ-ACK分别对应不同的优先级，例如DCI 1指示LP，DCI 2指示高优先级(High Priority，HP)，且DCI 1和DCI 2指示的PUCCH所在cell不同。则采用以下任一方式：
方式1：在时隙n，UE分别在不同的cell上反馈LP HARQ-ACK和HP HARQ-ACK,即UE还在cell 1上反馈DCI 1对应的PDSCH的HARQ-ACK，在cell2上反馈DCI 2对应的PDSCH的HARQ-ACK；
方式2：在时隙n，UE在HP HARQ-ACK所在cell上反馈HP HARQ-ACK和LP HARQ-ACK，即在cell2上反馈DCI1和DCI 2对应的PDSCH的HARQ-ACK；
方式3：在时隙n，UE在HP HARQ-ACK所在cell上反馈HP HARQ-ACK，即在cell2上仅反馈DCI 2对应的PDSCH的HARQ-ACK，DCI 1对应的PDSCH的HARQ-ACK不反馈；
方式4：如果UE支持同时在两个cell上传输PUCCH，则方式1，否则方式2或3。
在现有技术中，PUCCH和PUCCH的复用/优先都是针对同一个cell的PUCCH。当支持多个cell上配置PUCCH资源时，则可能出现PUCCH在不同的cell的场景。如图8所示，例如DCI指示HARQ-ACK在cell 1上反馈，而调度请求(Scheduling Request，SR)是配置的UL传输，根据PUCCH cell时间pattern确定其在cell2上。此时执行以下任一项方式:
方式1：UE根据DCI的指示确定PUCCH所在cell；
方式1-1：UE将SR与HARQ-ACK复用在HARQ-ACK所在cell的PUCCH；
方式1-2：丢弃SR，传输HARQ-ACK only；
方式1-3：当HARQ-ACK PUCCH为数据包流(Packet Flow，PF)1,SR为PF 1时，丢弃SR,传输HARQ-ACK，其余情况，将按照现有技术处理。
方式法2：UE根据HP UCI所在cell确定PUCCH所在cell。
方式3：(如果UE能力支持)UE在两个不同的cell上分别传输。
