Description

一种上行控制信道调度单元的确定方法、基站和用户设备
相关申请的交叉引用
本申请基于申请号为201711107748.1、申请日为2017年11月10日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本公开涉及无线通信技术领域但不限于无线通信技术领域，尤其涉及一种上行控制信道调度单元的确定方法、基站和用户设备。
背景技术
5G NR(New Radio)是正在进行的3GPP(第三代合作伙伴)的研究项目，它确定了基于正交频分复用(OFDM)的新无线空口标准，并将成为下一代移动网络的基础。
在NR系统中，调度单元(例如时隙(slot)，下文以slot为例来说明)的结构有多种，可以由基站灵活配置，在一些情况下，slot可以由下面的一个或多个部分组成：下行传输部分、上行传输部分、保护间隔(GAP)部分，并且每一个部分占用的OFDM符号数是可以配置的。也就是说，一个slot中用于上行传输的OFDM符号个数是变化的，且变化范围为0至14。
在NR系统中，上行控制信道(Physical Uplink Control Channel，PUCCH)分为短PUCCH(short PUCCH)和长PUCCH(long PUCCH)，其中，短PUCCH主要用于小区中心区域的用户设备(User Equipment，UE)发送及时的确认/否定确认(Acknowledgement/Negative Acknowledgement，ACK/NACK)反馈或其他信道状态信息(Channel State Information，CSI)，一般位于slot的末尾几个OFDM符号(例如下行slot的末尾1或2个OFDM符号；或者上行slot的末尾1或2个OFDM符号)；或者放置在slot内上行数据之前的几个符号；长PUCCH主要用于小区边缘的UE，其占用更多的 OFDM符号，以提升长上行控制信道的传输覆盖。长PUCCH一般包括4至14个OFDM符号，允许跨多个slot，详细的实施方法仍然在讨论中。
在NR系统中，PUCCH允许跨多个slot，例如，一个PUCCH需要更多上行OFDM符号，但是一个slot中没有足够的OFDM符号，所以需要更多的slot以提供足够的OFDM符号。当基站为UE配置跨多个slot的PUCCH时，基站会通知UE PUCCH的起始slot，以及需要跨slot的个数，例如，基站会通知UE跨多个slot的PUCCH的起始slot为slot n，需要跨slot的个数为4，但是，由于slot的结构是动态变化的，即slot n之后的slot结构中有下行为主的slot(slot中下行OFDM符号多于上行OFDM符号)、上行为主的slot(slot中上行OFDM符号多于下行OFDM符号)、纯上行slot、纯下行slot、预留的slot等等，UE除起始slot外的剩下的3个slot应该如何选择，如何进行资源调度，才能满足NR系统的不同通信需求，以很好的平衡资源的有效利用和通信质量。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚明白，下文中将结合附图对本公开的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
需要特别说明的是，本文中以时隙slot为例来说明调度单元，所述调度单元包含若干个连续的OFDM符号，可以是纯上行调度单元或纯下行调度单元，也可以是上行和下行混合的调度单元。本文中的slot可以是常规的slot，比如，目前，NR规定在不超过6GHz的频段，slot的符号数量为7个或14个OFDM符号，在超过6GHz的频段，slot的符号数据至少为14 个，其他数值待定；本文中的slot也可以是迷你时隙(mini-slot，也可以称为迷你调度单元)，比如，在NR中，目前定义的mini-slot包含的符号数据为(1～slot的符号总数-1)，明显的，mini-slot的符号数变化范围很大。
下面的各个实施例可以独立存在，且不同实施例中的技术特点可以组合在一个实施例中联合使用；文中未特殊说明的PUCCH资源可以是短PUCCH资源和/或长PUCCH资源；本文中的PUCCH对应物理上行控制信道(也有按照传输特性称谓的，例如上行控制区域或上行控制)；在NR的标准制定中，PUCCH也有可能被缩写为NR-PUCCH等其它缩写，但是其本意仍然为物理上行控制信道，承载内容未变化，所以称谓并不用于限定本申请的保护范围。

在一些实施例中，所述后续的调度单元的类型仅为上行调度单元。
在一些实施例中，所述上行控制信道在每个所述调度单元中使用的符号位置是连续的。
本公开实施例还提供了几个优选的实施例对本公开进行进一步解释，但是值得注意的是，该优选实施例只是为了更好的描述本公开，并不构成对本公开不当的限定。下面的各个实施例可以独立存在，且不同实施例中的技术特点可以组合在一个实施例中联合使用。本文中的PUCCH对应物理上行控制信道(也有按照传输特性称谓的，例如上行控制区域或上行控制)。在NR的标准制定中，PUCCH也有可能被缩写为NR-PUCCH等其它缩写，但是其本意仍然为物理上行控制信道，承载内容未变化，所以称谓不影响本文中的方法实施。
在本实施例中，在选择调度单元时，将所述起始调度单元之后的预留调度单元和/或未知(Unknown)调度单元和/或随机接入信道(Random Access Channel，RACH)调度单元排除掉，在上行调度单元和下行调度单元中选择。其中，下行调度单元包括纯下行调度单元和下行为主的调度单元。上行调度单元包括纯上行调度单元和上行为主的调度单元。如果是上行为主的调度单元时，要求上行为主的调度单元包含的符号数满足要求。如果是下行为主的调度单元时，要求下行为主的调度单元包含的符号数满 足要求。其中，所述符号是给NR系统使用的，且允许上行控制信道使用的符号，所述符号包括上行符号。
基站和UE分别根据规则，从起始调度单元开始向后推导PUCCH使用的调度单元以及PUCCH在推导出的调度单元中的映射。具体为：将所述起始调度单元之后的预留调度单元和/或Unknown调度单元和/或RACH调度单元排除掉，在上行调度单元和下行调度单元中选择。其中，下行调度单元包括纯下行调度单元和下行为主的调度单元。上行调度单元包括纯上行调度单元和上行为主的调度单元。如果是上行为主的调度单元时，要求上行为主的调度单元包含的上行符号数满足要求。如果是下行为主的调度单元时，要求下行为主的调度单元包含的下行符号数满足要求。
在一个载波中，slot n被指示为PUCCH的起始slot，假设PUCCH被配置需要跨3个slot，且每个slot中有4个上行OFDM符号来承载PUCCH。那么UE还需要确定从slot n之后的另外2个slot来承载PUCCH。在本实施例中，基站和UE按照下面的规则来确定剩余的slot。
假设如果slot n+1是一个预留slot，那么UE将不选择其作为剩余的slot来承载PUCCH；如果slot n+2是一个Unknown的slot，那么UE将不选择其作为剩余的slot来承载PUCCH；如果slot n+3是一个上行slot，且包含的上行符号数满需要求，例如有4个连续的上行符号，如果slot n+4是一个下行slot，但包含的上行符号数满足要求，例如有4个连续的上行符号，这样，slot n+3和slot n+4被选择作为后续的slot来承载PUCCH。这样，承载UE的PUCCH的slot将有slot n，slot n+3和slot n+4。这里需要说明的是，基站也是根据相同的规则来选择接收PUCCH的后续slot的，那么基站应该确保被选择的slot承载PUCCH的符号不被作为它用。
基站是配置了slot类型，包括slot中的OFDM符号属性，并将这些配置信息通知给UE的。所以，基站和UE都是获知了slot类型的，UE按照约定好的规则选择了slot n+3和slot n+4作为承载PUCCH的后续slot，基站也是可以知道的，这样，UE使用选定的3个slot承载PUCCH发送给基站，基站按照约定规则，推算UE选定的3个slot(实际只有后面2个slot，第一个被基站指示了)，从中接收PUCCH。
下面有2个补充说明针对一些特殊情况：
补充1：
当基站通知UE关于slot类型的信令(目前基站能够通过物理层信令下行控制信息(Downlink Control Information，DCI)来通知UE关于slot的类型，也可以通过高层信令来通知UE关于slot的类型)，没有被UE正确接收时，UE将不能确定slot类型，此时UE只能在基站指示的slot n中发送PUCCH，UE不再确定slot n之后的slot。基站如果在slot n中检测UE发送的PUCCH，然后在后续UE选定的slot中也尝试接收PUCCH，如果接收不到，则认为UE丢失了slot类型指示信令。
补充2：
如果基站未配置UE接收slot类型的信令(目前基站能够通知UE是否接收slot类型的配置信息)，那么当PUCCH被配置需要多个(例如3个)slot来承载PUCCH时，基站指示起始slot为slot n，然后基站需要为UE配置slot n之后连续多个(PUCCH要求的slot个数)的slot类型中的OFDM符号满足承载PUCCH的需求。例如，基站配置UE的PUCCH跨3个slot，基站配置起始slot为slot n，基站需要配置slot n+1，slot n+2的类型中有承载UE的PUCCH的OFDM符号数量和位置(如果每个slot中承载PUCCH的OFDM位置相同)，这样UE接收到PUCCH需要跨3个且起始slot为slot n时，那么UE认为承载PUCCH的slot从指示的起始slot n开始，之后slot n+1和slot n+2也是承载该PUCCH的slot。
在本实施例中，在选择调度单元时，将所述起始调度单元之后的下行调度单元和/或预留调度单元和/或Unknown调度单元和/或RACH调度单元排除掉，在上行调度单元中选择。其中，下行调度单元包括纯下行调度单元和下行为主的调度单元。上行调度单元包括纯上行调度单元和上行为主的调度单元。如果是上行为主的调度单元时，要求上行为主的调度单元包含的上行符号数满足要求。
基站和UE分别根据规则，从起始调度单元开始向后推导PUCCH使用的调度单元以及PUCCH在推导出的调度单元中的映射。具体为：将所述起 始调度单元之后的下行调度单元和/或预留调度单元和/或Unknown调度单元和/或和/或RACH调度单元排除掉，在上行调度单元中选择。其中，下行调度单元包括纯下行调度单元和下行为主的调度单元。上行调度单元包括纯上行调度单元和上行为主的调度单元。如果是上行为主的调度单元时，要求上行为主的调度单元包含的上行符号数满足要求。
在本实施例中，相对于前述实施例，只是对于PUCCH需要的多个调度单元中将下行调度单元不再作为承载PUCCH的调度单元，承载PUCCH的调度单元只能从上行调度单元中选择。
具体的选择可以参考可以参见前述实施例，这里不再赘述。
在本实施例中，在选择调度单元时，要求PUCCH在跨多个slot时，PUCCH在所述多个slot中包含符号个数和符号位置相同。如果调度单元中具有满足要求的符号个数和符号位置，该调度单元被认为是作为PUCCH跨多个slot的slot。
基站和UE分别根据规则，从起始调度单元开始向后推导PUCCH使用的调度单元以及PUCCH在推导出的调度单元中的映射。具体为：要求PUCCH跨多个slot，且PUCCH在所述多个slot中包含符号个数和符号位置相同。如果调度单元中具有满足要求的符号个数和符号位置，该调度单元被认为是作为PUCCH跨多个slot的slot。这里没有区分slot的类型，仅仅是按照slot中是否有可用的上行OFDM符号数和位置作为要求，也就是不管是什么类型的slot，只要满足上述的符号数和符号位置就可以作为承载跨slot的PUCCH的后续slot。
在一个载波中，slot n被指示为PUCCH的起始slot，假设PUCCH被配置需要跨3个slot，且每个slot中有4个上行OFDM符号(例如，为slot中符号3～6，符号编号从0开始，slot中包含14个符号)来承载PUCCH。那么UE还需要确定从slot n之后的另外2个slot来承载PUCCH。在本实施例中，基站和UE按照下面的规则来确定剩余的slot。
假设如果slot n+1是一个预留slot，只要slot有满足要求的OFDM符号个数和符号位置就可以被选择。假设该slot n+1中没有满足要求的OFDM符号数和符号位置(这些符号是给NR使用的，且允许PUCCH使用，如果 被预留为其他使用时，也跳过这些slot)，那么UE将不选择slot n+1作为剩余的slot来承载PUCCH。如果slot n+2是一个Unknown的slot，UE判断它是否能被选择作为后续的承载PUCCH的slot的原则仍然按照符号数和符号位置。假设该slot n+2中没有要求的OFDM符号数和符号位置。如果slot n+3和slot n+4中都有要求的符号数和符号位置，slot n+3和slot n+4被选定作为后续承载PUCCH的slot，这里不管slot n+3和slot n+4的类型。这样，按照slot中是否同时有要求的符号数和符号位置，选定了slot n+3和slot n+4被选择作为后续的slot来承载PUCCH。这样，承载UE的PUCCH的slot将有slot n，slot n+3和slot n+4，其中slot n是基站通过信令指示的，slot n+3和slot n+4是基站和UE根据约定规则选定的。
这里需要说明的是，基站也是根据相同的规则来选的接收PUCCH的后续slot的，那么基站应该确保被选择的slot承载PUCCH的符号不被作为它用。
基站是配置了slot类型，包括slot中的OFDM符号属性，并将这些配置信息通知给UE的。所以，基站和UE都是获知了slot类型的，所以UE按照约定好的规则选的了slot n+3和slot n+4作为承载PUCCH的后续slot，基站也是可以知道的，这样，UE使用选定的3个slot承载PUCCH发送给基站，基站按照约定规则，推算UE选定的3个slot(实际只有后面2个slot，第一个被基站指示了)，从中接收PUCCH。对于PUCCH所要跨多个slot，如果起始slot之后的slot中有满足要求的上行OFDM符号数和/或符号位置，基站要保证这些slot中的所述上行OFDM符号能够被所述PUCCH使用。具体的，基站知道确定后续slot的规则，所以基站在这些将被确定为承载所述PUCCH的slot中的上行OFDM符号不被其他信道/数据使用。
在本实施例中，在选择调度单元时，要求PUCCH跨多个slot，且PUCCH在所述多个slot中包含符号个数相同。如果调度单元中具有满需要求的符号个数，该调度单元被认为是作为PUCCH跨多个slot的slot，但是PUCCH在该slot中的映射的起始符号位置被调整。
基站和UE分别根据规则，从起始调度单元开始向后推导PUCCH使用 的调度单元以及PUCCH在推导出的调度单元中的映射。具体为：当要求PUCCH在跨多个slot时，且PUCCH在所述多个slot中包含符号个数相同的。如果调度单元中具有满需要求的符号个数，该调度单元被认为是作为PUCCH跨多个slot的slot，但是PUCCH在该slot中的映射的起始符号位置被调整。这里没有区分slot的类型，仅仅是按照slot中是否有可用的上行OFDM符号数作为要求(符号位置不作为要求)，也就是不管是什么类型的slot，只要满足上述的符号数就可以作为承载跨slot的PUCCH的后续slot。
在一个载波中，slot n被指示为PUCCH的起始slot，假设PUCCH被配置需要跨3个slot，且每个slot中有4个上行OFDM符号来承载PUCCH。那么UE还需要确定从slot n之后的另外2个slot来承载PUCCH。在本实施例中，基站和UE按照下面的规则来确定剩余的slot。
假设如果slot n+1是一个预留slot，只要slot有要求的OFDM符号个数就可以被选择。假设该slot n+1中没有满足要求的OFDM符号数(这些符号是给NR使用的，且允许PUCCH使用，如果被预留为其他使用时，也跳过这些slot)，那么UE将不选择slot n+1作为剩余的slot来承载PUCCH。如果slot n+2是一个Unknown的slot，UE判断它是否能被选择作为后续的承载PUCCH的slot的原则仍然按照符号数。假设该slot n+2中没有满足要求的OFDM符号数。如果slot n+3和slot n+4中都有满足要求的符号数，slot n+3和slot n+4被选定作为后续承载PUCCH的slot，这里不管slot n+3和slot n+4的类型。在一些实施例中，如果slot n+3中要求的OFDM符号数对应的符号位置也是和slot n中PUCCH使用的符号位置相同，那么slot n+3中就使用与slot n相同的符号位置承载PUCCH。如果slot n+4中要求的OFDM符号数，但是符号位置与slot n中承载PUCCH的符号位置不同。这里假设slot n中承载PUCCH的符号数是4个且为符号3～6(slot中符号编号从0开始)，被选定的slot n+3中承载PUCCH的符号位置和slot n是相同的。假设slot n+4中承载PUCCH的符号数也是4，但是上行符号的符号位置从4～14，有10个上行符号，此时承载所述PUCCH的符号被调整为从该slot n+4的第一个上行符号开始计算，共连续4个符号，即符号4～7。也就是说选定的slot n+4中承载所述PUCCH的符号为4～7。显然，slot n+4中承载所述PUCCH的符号位置被调整了，不同于slot n和slot n+3中的符号位 置。本实施例中隐含被调整的符号位置为该slot中(或本UE获知该slot中)第一个上行符号开始的，调整的规则也要基站和UE事先约定好。
这样，按照slot中是否同时有满足要求的符号数，选定了slot n+3和slot n+4被选择作为后续的slot来承载PUCCH，但是slot n+4中调整了承载所述PUCCH的符号位置。这样，承载UE的PUCCH的slot将有slot n，slot n+3和slot n+4，其中，slot n是基站通过信令指示的，slot n+3和slot n+4是基站和UE根据约定规则选定的。
这里需要说明的是，基站也是根据相同的规则来选的接收PUCCH的后续slot以及slot中承载PUCCH的符号位置，那么基站应该确保被选择的slot承载PUCCH的符号不被作为它用。
基站是配置了slot类型，包括slot中的OFDM符号属性(上行符号，下行符号或预留符号或GAP符号等)，并将这些配置信息通知给UE的。所以，基站和UE都是获知了slot类型的，所以UE按照约定好的规则选的了slot n+3和slot n+4作为承载PUCCH的后续slot，包括调整了slot n+4中的承载所述PUCCH的起始符号，基站也是可以根据约定的调整符号位置来获知，这样，UE使用选定的3个slot承载PUCCH发送给基站，基站按照约定规则，推算UE选定的3个slot(实际只有后面2个slot，第一个被基站指示了)，从中接收PUCCH。对于PUCCH所要跨多个slot，如果起始slot之后的slot中有满足要求的上行OFDM符号数和/或符号位置，基站要保证这些slot中的所述上行OFDM符号能够被所述PUCCH使用。具体的，基站知道确定后续slot的规则，所以基站在这些将被确定为承载所述PUCCH的slot中的上行OFDM符号不被其他信道/数据使用。
描述上述实施例的方法中，在不冲突的情况下可以结合使用。
例如，前述的两个实施例的技术特征结合，那么UE在选择后续slot时，先按照slot类型排除了预留slot和Unknown slot，起始slot之后，只要下行slot或上行slot中包含的上行符号数和符号位置与PUCCH的起始slot中承载该PUCCH的符号数和符号位置相同，就选定该slot。未尽描述可以参考前述对应的实施例。

例如，前述两个实施例中的技术特征结合，那么UE在选择后续slot时，先按照slot类型排除了预留slot，Unknown slot和下行slot，从指示的起始slot之后只要上行slot中包含的上行符号数和符号位置与PUCCH的起始slot中承载该PUCCH的符号数和符号位置相同，就选定该slot。未尽描述可以参考前述对应的实施例。
本实施例中还包括，基站为UE指示具体按照哪种方式进行PUCCH跨多个slot时的后续slot确定。例如，优选实施例3中的方式和实施例中的方式都被一个系统支持，那么基站能够通过信令(包括高层信令或物理层信令或介质访问控制(Medium Access Control，MAC)层信令)通知UE，使用具体哪种方式确定PUCCH要跨的slot。高层信令可以是广播类RRC消息或UE专用无线资源控制(Radio Resource Control，RRC)消息。物理层信令可以是通过DCI来承载的，包括公共DCI或UE专用DCI。MAC层信令可以是MAC层的控制单元。这种指示可以增加系统的鲁棒性。
与上述实施例有所不同，该实施例解决的是，当一个PUCCH跨多个slot时，如果允许PUCCH在每个slot中有不同的OFDM符号数，那么所述多个slot中，具体如何确定PUCCH在每个slot中的符号数。
PUCCH(1～2bit UCI对应的PUCCH)跨多个slot时，后续slot满足下 面要求即可被选择：如果承载该PUCCH时，要求该PUCCH的OCC复用能力与起始slot中承载该PUCCH的复用能力相同。PUCCH在slot内跳频时，每个跳频单独计算OCC复用能力，PUCCH在slot中不跳频时，按照整体计算OCC复用能力。
对于PUCCH还按照传输的比特数区分为不同的格式，但是包含的符号数大于4，例如，对于传输1～2比特信息设置了一种PUCCH传输格式，在时域时域OCC复用方式(记为格式1)；对于传输大于3bit且小于X比特设置了一种PUCCH传输格式，在频域时域OCC复用方式；对于传输大于X比特设置了一种PUCCH传输格式，不支持复用方式。
如果上述的PUCCH格式跨多个slot发送(这些格式也适用实施例1～5)，下面介绍所述多个slot中用来承载该PUCCH的符号个数不同的情况。例如，PUCCH需要跨3个slot，但是三个slot中能够给该PUCCH使用的上行符号个数不是完全相等。对于所述多个slot承载该PUCCH的符号个数不等的情况，具体怎么处理呢？例如，第1和2个slot分别只有一个符号为该PUCCH，第二个slot有8个符号，这种跨多个slot的PUCCH结构显然不是最佳的。那么在所述多个slot承载该PUCCH符号数不等的情况下，如何设计出最佳的不等符号数呢？下面介绍一种方法。
一般的，对于跨多个slot的PUCCH，基站指示PUCCH的起始slot，并会配置在起始slot中的起始符号和长度(符号数)，以及slot个数，那么后续的slot怎么确定呢，后续的slot具备什么特征就能被选择呢？一种方式是，对于上述的PUCCH格式1(参考现有NR中PUCCH格式1或1～2比特的长PUCCH的结构)，当跨多个slot时，每个slot中承载该PUCCH的符号数差值受OCC复用能力的限制。对于后续slot的选择，基本原则是后续有slot承载该PUCCH时，如果该PUCCH在该slot中具有与起始slot中承载该PUCCH具有相同的OCC复用能力，该slot就能被选择。如果该PUCCH跳频在slot内，那么对于后续slot的选择，基本原则略微改为后续有slot承载该PUCCH时，如果该PUCCH在该slot中具有与起始slot中承载该PUCCH的每个跳频分别具有相同的OCC复用能力，该slot就能被选择。
在本公开一实施例中，基站为UE配置跨多个slot的PUCCH，并通知UE起始slot，以及起始slot中PUCCH的起始符号和PUCCH持续的符号数，PUCCH需要跨的slot个数，以及是否跳频等信息。然后基站和UE约定按照上述的原则确定PUCCH后续选择使用的slot。UE在选择的slot上继续发送该PUCCH，基站在该slot上继续进行接收该PUCCH。假设，基站配置UE的PUCCH跨2个slot，起始slot为slot n，并且起始slot中该PUCCH使用7符号，且起始符号未符号3(标号从0开始)，且不跳频。那么对于该PUCCH而言，后续还需要一个slot。这里，假设slot n+1中没有上行符号，所以slot n+1未被选择，slot n+2中有6个可以使用的上行符号，查下表1，可以发现在slot中，当该PUCCH不调频时，符号数是6个或7个时，其OCC的复用能力相同，所以，此时slot n+2能被选择来承载该PUCCH。这样，该PUCCH使用的slot为slot n和slot n+1。
在一些实施例中，后续slot的选择还可以结合该slot中如果传输该PUCCH时，使用的符号的起始位置是否相同，例如，设置严格的条件时，则再要求该PUCCH在多个slot中的起始符号也要相同；又例如，设置严格的条件时，则不要求该PUCCH在多个slot中的起始符号也要相同，此时只要满足OCC复用能力相同即可，但是要约定该PUCCH在该slot中的起始符号位置，例如约定为该slot中第一个可以用的上行符号。
对于配置跨多个slot的PUCCH的后续slot选择，该PUCCH在后续被选择的slot中的OCC复用能力要和起始slot中该PUCCH的OCC复用能力相同。此时后续被选择的slot中为该PUCCH使用的符号数可以不等于起始slot中该PUCCH使用的符号数，也就是说所述多个slot中用于承载该PUCCH的符号数可以彼此不相等(当然也可以相等)。后续被选择的slot中承载该PUCCH的符号位置，也可以允许调整，调整的规则可以约定。这样可供UE选择slot将会更多些。

表1
在本公开另一实施例中，约定的原则中PUCCH支持跳频。此时选择后续slot时，slot需要满足：如果该PUCCH在该slot中承载且跳频时，第一个跳频的OCC复用能力与起始slot中该PUCCH的第一个跳频的OCC复用能力相同，第二个跳频的OCC复用能力与起始slot中该PUCCH的第二个跳频的OCC复用能力相同。这样，该slot就可以被选择。如果还要设置更加严格的条件，可以设置该slot中承载PUCCH的起始符号也要和起始slot中承载该PUCCH的起始符号相同。
在本实施例中，在选择调度单元时，PUCCH(对于大于3比特UCI对应的PUCCH)跨多个slot，后续slot满足下面要求即可被选择：如果承载该PUCCH时，要求在该slot中承载的PUCCH的母码长度与起始slot中该 PUCCH的母码长度相同(频域资源与起始slot相同)。
对于承载大于2比特信息的PUCCH，由于不支持时域OCC复用，所以这种PUCCH在跨多个slot时，它的后续slot选择的原则有所不同。这种PUCCH跨多个slot时，后续的slot选择，满足条件为：如果该slot中承载该PUCCH，此时该slot中用于承载该PUCCH的资源(时域和频域，时域是符号，频域是PRB)承载该PUCCH编码后的比特来自的母码长度与起始slot中该PUCCH编码后的比特来自的的母码长度相同，此时该slot可以被选择。
如果继续设置严格的条件，可以再要求所述资源中，频域资源不允许增加(即该slot中用于该PUCCH的频域资源与起始slot中为该PUCCH使用的频域大小相同)。也可以再要求该PUCCH在该slot中起始符号与在起始slot中的起始符号相同。也可以再要求在该slot中承载的该PUCCH编码比特的码率超过某一门限，由于虽然编码比特来自同一母码长度，但是码率过大时会降低译码性能的，所以设置合理的码率门限以保证译码性能。码率的门限可以通过仿真获得，也可以在该PUCCH允许使用的码率中选择某一码率值。这里需要强调的是，上述一个或多个条件之间可以结合使用或单独使用。
本公开提供的上行控制信道调度单元的确定方法、基站和用户设备，通过根据约定的规则来确定用户设备的上行控制信道使用的调度单元，解决了跨多个slot的PUCCH在起始slot之后如何确定哪些slot来承载所述PUCCH的问题。本公开提供了多种解决方式，这些解决方式都可以利用约定规则来确定slot，不需要额外的信令通知。
本申请中，各个实施例中的技术特征，在不冲突的情况下，可以组合在一个实施例中使用。每个实施例仅仅是本申请的最优实施方式，并不用于限定本申请的保护范围。
本实施例提供一个技术问题为：如何根据UE的最大处理能力确定UE数据传输时的用于解调的参考信号(De Modulation Reference Signal，DMRS)和数据的复用方式？复用方式为时分复用(TDM)或频分复用(FDM)。这里的UE的最大处理能力是指包括UE接收到基站发送的物理下行控制信道 (Physical Downlink Control Channel，PDCCH)调度上行数据(包括数据需要的DMRS)，以及解码该PDCCH，以及按照PDCCH调度信息准备上行数据等，直到可以发送上行数据所需要的最小时长，这里记为N2。UE处理能力越强，N2的取值越小。一般的，UE的能力值N2会上报给基站。
实际当中，由于上行发送数据时跟下行有时间错位，所以基站还会配置给用户一个TA值，用于用户在发送数据时提前的时间单位。所以，从调度用户数据的PDCCH最后一个符号到真正用户能发送PUSCH的第一个数据符号的最小距离是跟N2和TA都有关系的。可以将PDCCH最后一个符号到PUSCH第一数据符号的最小符号个数称之为K2，即K2跟UE的能力N2还有TA等有关系。比如PDCCH最后一个符号在符号n上，如果PDCCH调度给用户的PUSCH从符号n+K2或者n+K2开始，那么该UE就有能力从n+K2上开始传输数据。为了降低用户的复杂度，或者为了给用户留更多的时间去准备数据的发送，可以默认的在PUSCH的第一个符号上只发送DMRS，而不发生数据。由于DMRS可以提前准备好的，所以用户就多了一个符号的时间来准备PUSCH中数据的发送。
然而这种默认的方式带来了很大的开销。因为始终认为DMRS和数据是TDM的，即不同时发送，即使DMRS没有占完第一个符号的所有子载波，也不能用于数据发送。
一种限制DMRS端口复用方式的方法，如果基站动态配置PUSCH的第一个符号是在对应PDCCH最后一个符号后K2+X个符号以后，那么PUSCH的DMRS和数据的复用方式包含FDM和TDM。这里所述的PUSCH和DMRS的复用方式是指第一个DMRS符号或者前2个连续的DMRS符号和PUSCH之间的复用方式。
如果基站动态配置PUSCH的第一个符号是在对应PDCCH最后一个符号后K2+X符号上，那么PUSCH的DMRS和数据的复用方式只包含TDM。
可选的，如果基站动态配置PUSCH的第一个符号是在对应PDCCH最后一个符号后K2+X符号上或者K2+X之前，且不超前于PDCCH最后一个符号后K2个符号，那么PUSCH的DMRS和数据的复用方式只包含TDM。
如果基站动态配置PUSCH的第一个符号是在对应PDCCH最后一个符 号后K2+X符号之前，很显然，用户没有足够时间准备数据的发送，那么此次用户将不会发送数据。
其中，K2是基于用户的能力N2计算出来的。
假设PDCCH的最后一个符号在一个时隙的符号n上发送，那么根据用户的能力N2计算得到的K2后，基站一般应该调度用户的PUSCH的第一符号不能超前于符号n+K2,否则用户没有足够时间准备。根据本文的发明，如果基站配置给用户PUSCH的第一个符号在n+K2到n+K2+X之间时，PUSCH的DMRS和数据的复用方式只包含TDM。因为此时不在第一个PUSCH符号上发送数据而只是发送DMRS可以为用户赢来一个符号的准备时间，用于发送数据。而如果基站配置给用户PUSCH的第一个符号在n+K2+X以后时，PUSCH的DMRS和数据的复用方式包含TDM和FDM。此时用户有足够的时间准备数据的发送，在第一个PUSCH的符号上发送数据可以有效提高资源利用率，其中，n是整数。
当X＝0时，就变成了，如果基站配置给用户PUSCH的第一个符号在符号n+K2上时，在PUSCH的第一个符号上就不能有数据发送，即DMRS和数据是TDM。而如果基站配置给用户PUSCH的第一个符号在符号n+K2以后时，在PUSCH的第一个符号上就可以数据发送，即DMRS和数据的复用方式包含TDM和FDM。如果PUSCH上的DMRS是配置了2个连续的DMRS符号，那么这2个符号上DMRS和数据的复用方式是一样的。
X是大于等于0的整数。X可以是预定义的，比如X预定义等于0，也可以是高层信令配置给用户的。
如图5所示，总共在一个DMRS符号上支持4个端口，且分为2个正交码分复用(CDM，Code Division Multiplexing)CDM组。端口p0、p1对应CDM组0，端口p2、p3对应CDM组1。一般当基站分配给用户端口0或者1时，基站需要告诉用户UE0在CDM组1上有没有其他用户发送DMRS，如果有，就如下表2中索引0、2的第5列所示，表示可能在CDM组1上有其他用户的DMRS发送，那么UE0在CDM组1上不能发送数据。此时对于UE0来说，在该DMRS的符号上DMRS和数据是TDM的。而如果像表2中索引1、3所示，CDM组上没有其他用户发送DMRS，那么UE0就 会在CDM组1上发送数据。
根据之前所述，如果基站配置给用户PUSCH的第一个符号在n+K2到n+K2+X之间时，表2中索引1、3是被禁止的。因为PUSCH的DMRS和数据的复用方式只包含TDM。而索引1、3包含了FDM的方式。也就是说，当基站配置给用户PUSCH的第一个符号在n+K2到n+K2+X之间时，用户不希望被配置一些DMRS端口配置，这些配置中包含有数据在DMRS的符号上发送。而如果基站配置给用户PUSCH的第一个符号在n+K2+X以后时，则没有限制。
Figure PCTCN2018115101-appb-000003
表2
或者说，如果基站配置给用户PUSCH的第一个符号在n+K2到n+K2+X之间时，在PUSCH的第一个或者前2个符号上，用于该用户DMRS端口传输的资源外所有资源不用于该用户发送数据。如果基站配置给用户PUSCH的第一个符号在n+K2+X符号后，在PUSCH的第一个或者前2个符号上，用于该用户DMRS端口传输的资源外剩余的资源是否用于该用户的数据传输，需要基站用物理层动态信令指示。
补充，对于X，K2，K2+X的可以是非负整数，这样以符号为单位。也可以非负的小数，此时按照时长来计数，例如纳秒。
