Description

一种上行控制信息传输方法及设备
本申请要求在2018年1月12日提交中国专利局、申请号为201810031117.4，发明名称为“一种上行控制信息传输方法及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，尤其涉及一种上行控制信息传输方法及设备。
背景技术
在长期演进(Long Term Evolution；LTE)系统中，用户设备向基站设备上报上行控制信息(Uplink Control Information；UCI)，该UCI用于基站设备调度终端设备的下行数据或者上行数据传输的依据。例如：基站设备通过物理下行共享信道(Physical Downlink Shared Channel；PDSCH)发送下行业务数据；用户设备在接收到下行业务数据后，在物理上行控制信道(Physical Uplink Control Channel；PUCCH)或者物理上行共享信道(Physical Uplink Shared Channel；PUSCH)上反馈用户设备对该下行业务数据的确认ACK或者非确认NACK信息，以便于基站设备确定重新调度该下行业务数据还是向该用户设备调度新的下行业务数据。
在实际应用中，考虑到用户设备的功耗，通常不被允许同时发送PUCCH和PUSCH。那么用户设备在与PUCCH时间重叠的PUSCH上发送本该在PUCCH上发送的UCI。
但是在新一代的通信系统(例如：5G通信系统)中，PUSCH和PUCCH在时间上更加灵活，也就是说，和PUCCH在时间上重叠的PUSCH的数量也比较多。对应地，从多个PUSCH中选择哪个PUSCH发送UCI，这对用户设备的处理能力要求不同。一旦选择的PUSCH不适合，要么对用户设备的处理能力提出更高的要求；要么导致下行数据传输时延的问题。
综上所述，亟需一种上行控制信息传输方法，以解决如何从与PUCCH在时间上重叠的多个PUSCH中确定用于发送UCI的PUSCH的问题。
发明内容

附图说明
为了更清楚地说明本申请实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简要介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域的普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
图1为现有技术中基站设备与用户设备之间传输上行控制信息的示意图；
图2为本申请实施例提供的一种上行控制信息传输方法的流程示意图；
图3为本申请实施例提供的一种上行控制信息传输方法的流程示意图；
图4为本申请实施例提供的一种上行控制信息传输设备的结构示意图。
具体实施方式
图1为现有技术中基站设备与用户设备之间传输上行控制信息的示意图。
从图1中可以看出，用户设备在PCell的PUCCH信道占用的资源是时隙Slot PCell_μ(n)内的符号第3～12个符号。
如果用户设备发送的UCI中包括HARQ-ACK，基站设备根据用户设备的处理能力指示用户设备在该PUCCH发送HARQ-ACK信息，可保证用户设备在t 01时刻完成PDSCH的接收解调、获取HARQ-ACK、并完成发送HARQ-ACK前的处理过程；并且，用户设备在t 02时刻完成PUCCH发送可保证该HARQ-ACK传输的时延满足下行数据传输的时延需求。如果用户设备发送的UCI中包括信道状态信息，终端设备对信道状态信息反馈的周期也能保证用户设备在t 01时刻准备好信道状态信息被发送前的编码调制等处理过程。
但是，如果在该PUCCH的时间范围内，用户设备被配置或者调度分别在SCell-1发送PUSCH-1、SCell-2发送PUSCH-2。其中PUSCH-1占用第1～5 个符号、PUSCH-2占用第10～14个符号。
如果用户设备在PUSCH-1发送本该在PUCCH发送的HARQ-ACK，则要求用户设备在PUSCH-1的起始时刻t 11完成PDSCH的接收解调、获取HARQ-ACK、并完成发送HARQ-ACK前的处理过程，则对用户设备的处理速度、能力提出了更高的要求。或者，如果UCI中包括信道状态信息，用户设备在PUSCH-1发送本该在PUCCH发送的信道状态信息也对用户设备测量下行信道状态，预处理待发送的信道状态信息的能力提出了更高的要求。
如果用户设备在PUSCH-2发送本该在PUCCH发送的HARQ-ACK，则用户设备在PUSCH-2的结束时刻t 12才能完成HARQ-ACK的发送。和该HARQ-ACK在PUCCH发送相比，基站设备获取到HARQ-ACK的时间推后，可能影响下行数据传输的时延性能。同样，如果UCI中包括信道状态信息，用户设备在PUSCH-2发送本该在PUCCH发送的信道状态信息导致基站设备获取到下行信道状态的时间推后，影响基站对该用户设备的数据调度的时间。
为了使本申请的目的、技术方案和优点更加清楚，本申请实施例提供了一种上行控制信息传输方法及设备，用户设备确定与上行控制信息UCI对应的物理上行控制信道PUCCH；并从与所述PUCCH在时间上有重叠的至少一个PUSCH中选择满足条件的一个PUSCH；在选择的所述PUSCH上将上行控制信息UCI传输给所述基站设备，所述UCI中包含所述用户设备对所述下行数据的ACK/NACK和或信道状态信息等。这里的条件可以根据用户设备支持的PDSCH的接收时间与所述下行数据对应的ACK/NACK的发送时间之间的时间差的阈值确定，也可根据至少一个PUSCH和PUCCH的结束时间确定，这样能够有效避免在PUSCH上发送上行控制信息带来的对用户设备处理能力的挑战，同时还能够保证下行数据传输性能。
下面结合说明书附图对本申请作进一步地详细描述，显然，所描述的实 施例仅仅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在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
图2为本申请实施例提供的一种上行控制信息的传输方法的流程示意图。所述方法可以如下所示。
步骤201：用户设备确定与上行控制信息UCI对应的物理上行控制信道PUCCH。
在本申请实施例中，用户设备根据配置信息或者调度信息确定UCI对应的PUCCH，这里对于确定方式不做具体限定。
步骤202：所述用户设备在第一物理上行共享信道PUSCH集合中的第一PUSCH发送所述UCI。
其中，所述第一PUSCH集合中包含的各PUSCH均和所述PUCCH在时间上有重叠。
需要说明的是，所述第一UCI中包含混合自动重传请求机制应答信息HARQ-ACK/NACK，所述HARQ-ACK/NACK对应于所述用户设备接收的至少一个下行数据，和或第一UCI中包含信道状态信息。
在本申请实施例中，用户设备在确定与UCI对应的PUCCH的情况下，由于不能同时发送PUCCH和PUSCH，那么用户设备可以放弃发送PUCCH，进而通过PUSCH发送UCI。用户设备不能同时发送PUCCH和PUSCH，可能是本身的能力不支持，也可能是网络设备通过配置信息指示该用户设备不被允许同时发送PUSCH和PUCCH。
用户设备根据确定的PUCCH的时间，确定与该PUCCH在时间上有重叠的PUSCH，这里的PUSCH可以是一个，也可以是多个。如果是多个，可以称之为第一PUSCH集合。
那么用户设备在第一PUSCH集合中的第一PUSCH发送所述UCI。
并非第一PUSCH集合中包含的任何一个PUSCH都可以作为第一 PUSCH，而是需要满足一定的条件，才能保证用户设备在发送第一PUSCH之前准备好需要发送的上行控制信息，例如：HARQ-ACK/NACK和或CSI。
进一步地，所述第一PUSCH属于第二PUSCH集合，所述第二PUSCH集合由所述第一PUSCH集合中满足设定条件的PUSCH组成。
本申请实施例中设定条件可以包含以下几种情况或者任意组合：
1、设定条件包含：PUSCH的起始时间和所述至少一个下行数据的结束时间之间的时间差不小于设定第一阈值。
其中，所述设定第一阈值对应于所述用户设备支持的时间差的最小值，所述时间差为物理下行共享信道PDSCH的结束时间和所对应的HARQ-ACK/NACK反馈的起始时间之间的时间差。
其中，所述设定第一阈值对应于所述用户设备支持的时间差的最小值，所述时间差为物理下行共享信道PDSCH的结束时间和所对应的HARQ-ACK/NACK反馈的起始时间之间的时间差。
由于用户设备在发送第一PUSCH之前需要完成下行数据的解调，确定HARQ-ACK/NACK信息以及HARQ-ACK/NACK信息的编码、调整、映射等处理，而这些处理又与终端设备的处理能力相关。因此，设定第一阈值通常选取所述用户支持的物理下行共享信道PDSCH的结束时间和所对应的HARQ-ACK/NACK反馈的起始时间之间的时间差的最小值或者临界值。
由于第一PUSCH集合中包含的PUSCH虽然与PUCCH在时间上有重叠，但并不是所有的PUSCH都满足设定条件。再者用户设备用于发送UCI的PUSCH还需要满足设定条件。这里的“设定条件”可以为PUSCH的起始时间和所述下行数据的结束时间之间的时间差不小于设定第一阈值。那么这里满足设定条件的PUSCH可以称之为第二PUSCH集合。
2、本申请实施例中记载的设定条件包含PUSCH的起始时间不早于所述PUCCH的起始时间。
较优地，在本申请实施例中，为了保证基站设备在PUCCH的起始时间 之后接收上行控制信息，那么用户设备所使用的第一PUSCH的起始时间不早于所述PUCCH的起始时间。用户设备在不早于PUCCH的第一PUSCH发送UCI，可避免对用户设备处理能力提出新的要求。
3、本申请实施例中记载的设定条件包含PUSCH的结束时间不晚于所述PUCCH的结束时间。
较优地，在本申请实施例中，考虑到如果第一PUSCH的结束时间晚于PUCCH的结束时间，那么导致基站设备接收到的上行控制信息时间较晚，将出现下行数据传输时延的问题。那么用户所使用的第一PUSCH的结束时间不晚于所述PUCCH的结束时间。
需要说明的是，上述列举的几种设定条件可以组合使用，也可以单独使用，这里不做具体限定。
可选地，对于第二PUSCH集合中包含的PUSCH，若所述第二PUSCH集合中满足设定条件的PUSCH的个数为至少两个，那么本申请实施例中记载的设定条件包含：所述第一PUSCH的起始时间在所述第二PUSCH集合中各PUSCH起始时间中最早和/或所述第一PUSCH所在小区在所述第二PUSCH集合中各PUSCH所在的小区中索引最小。
具体地，用户设备所使用的第一PUSCH个数为一个，假设通过上述条件判断之后得到的满足设定条件的PUSCH的个数大于1，那么需要保证第一PUSCH是第二PUSCH集合中起始时间最早的；或者，需要保证第一PUSCH所在的小区是所述第一PUSCH所在小区在所述第二PUSCH集合中各PUSCH所在的小区中索引最小；需要保证第一PUSCH是第二PUSCH集合中起始时间最早的且第一PUSCH所在的小区是所述第一PUSCH所在小区在所述第二PUSCH集合中各PUSCH所在的小区中索引最小。
通过本申请实施例提供的技术方案，用户设备确定与上行控制信息UCI对应的物理上行控制信道PUCCH；在物理上行共享信道PUSCH集合中的第一PUSCH发送所述UCI；其中，所述PUSCH集合中包含的各PUSCH均和 所述PUCCH在时间上有重叠。这样能够有效避免在PUSCH上发送上行控制信息带来的对用户设备处理能力的挑战，同时还能够保证下行数据传输性能。
基于同一个发明构思，图3为本申请实施例提供的一种上行控制信息传输方法的流程示意图。所述方法可以如下所示。
步骤301：用户设备接收基站设备在物理下行共享信道PDSCH上发送的下行数据。
在本申请实施例中，基站设备可以通过物理下行控制信息调度向用户设备发送的下行数据。这里用户设备接收的下行数据可以是一个也可以是多个，即这里记载的PDSCH可以是一个PDSCH集合，该PDSCH集合中包含至少一个PDSCH。
步骤302：所述用户设备确定与所述PDSCH对应的物理上行控制信道PUCCH。
在本申请实施例中，与所述PDSCH对应的物理上行控制信道PUCCH可以理解为与PDSCH集对应的PUCCH。这里“对应”关系的建立可以是根据物理下行控制信息的指示确定的，也可以是根据预设的定时差确定的，这里对于具体实现方式不做具体限定。
较优地，在确定PUCCH之后，用户设备可以根据时间确定与该PUCCH在时间上有重叠的至少一个PUSCH，得到PUSCH集。在该PUSCH集合中包含的PUSCH可以位于一个小区，也可以位于不同小区，这里不做具体限定。
步骤303：所述用户设备从与所述PUCCH在时间上有重叠的至少一个物理上行共享信道PUSCH中选择满足条件的一个PUSCH。
在本申请实施例中，所述用户设备从与所述PUCCH在时间上有重叠的至少一个物理上行共享信道PUSCH中选择在时间上满足所述PDSCH的接收时间与所述下行数据对应的ACK/NACK的发送时间之间的时间差要求。
具体地，所述用户设备确定接收到所述PDSCH的接收时间和确定所述 下行数据对应的确认ACK/非确认NACK的发送时间；
所述用户设备从与所述PUCCH在时间上有重叠的至少一个物理上行共享信道PUSCH中选择一个PUSCH，所述PUSCH在时间上满足所述PDSCH的接收时间与所述下行数据对应的ACK/NACK的发送时间之间的时间差要求。
如果用户设备接收到的所述下行数据为至少两个，那么所述用户设备从与所述PUCCH在时间上有重叠的至少一个物理上行共享信道PUSCH中选择满足条件的一个PUSCH，包括：
首先，所述用户设备确定接收到所述PDSCH的接收时间；以及针对每个所述下行数据，执行以下操作：
所述用户设备确定该下行数据对应的确认ACK/非确认NACK的第一发送时间，并根据所述接收时间，计算所述接收时间与该下行数据对应的第一发送时间之间的时间差。
其次，所述用户设备确定每个所述下行数据对应的PDSCH的结束时间；并针对每一个所述PUSCH，执行以下操作：
所述用户设备计算该PUSCH的起始时间与每个所述下行数据对应的PDSCH的结束时间之间的时间差，得到多个时间差值；
在得到各所述PUSCH对应的多个时间差值之后，所述用户设备从与所述PUCCH在时间上有重叠的至少一个物理上行共享信道PUSCH中选择每个所述时间差值均不小于设定第一阈值的PUSCH；
其中，所述设定第一阈值对应于所述用户设备支持的时间差的最小值，所述时间差为物理下行共享信道PDSCH的结束时间和所对应的HARQ-ACK/NACK反馈的起始时间之间的时间差。
较优地，所述方法还包括：
若选择每个所述时间差值均不小于设定第一阈值的PUSCH个数为多个，那么所述用户设备确定选择的各所述PUSCH的起始时间；
所述用户设备根据所述起始时间，选择所述起始时间不早于所述PUCCH的起始时间的PUSCH。
较优地，所述方法还包括：
若选择每个所述时间差值均不小于设定第一阈值的PUSCH个数为多个，那么所述用户设备确定选择的各所述PUSCH的结束时间；
所述用户设备根据所述结束时间，选择所述结束时间不晚于所述PUCCH的结束时间的PUSCH。
通过上述方式，假设选择的PUSCH个数为多个，那么所述用户设备选择起始时间最早和/或所在小区的索引最小的PUSCH。
步骤304：所述用户设备在选择的所述PUSCH上将上行控制信息UCI传输给所述基站设备，所述UCI中包含所述用户设备对所述下行数据的确认ACK/非确认NACK。
需要说明的是，本申请实施例中记载的UCI除了包含所述用户设备对所述下行数据的确认ACK/非确认NACK之外，还可以包含CSI(Channel State Information；信道状态信息)和RI(Rank Indication；秩指示)等。
