技术领域
本公开实施例涉及通信技术领域，具体涉及一种处理上行控制信息(Uplink Control Information，UCI)的方法及设备。
背景技术
与相关技术中的移动通信系统相比，未来第五代移动通信技术(Fifth-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。5G的主要场景包括：增强型移动宽带(Enhance Mobile Broadband，eMBB)，超高可靠与低延迟的通信(Ultra Reliable&Low Latency Communication，URLLC)，海量机器类通信(massive Machine Type Communication，mMTC)，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。
对于某些终端可能支持不同数值配置(numerology)的业务，例如：终端既支持URLLC低时延高可靠业务，同时支持大容量高速率的eMBB业务，可以同时在两种或多种数值配置的下行控制信道和下行数据信道接收，以及同时在两种或多种数值配置的上行控制信道上行数据信道发送，如图1所示。
当有多个UCI分别承载在不同物理上行控制信道(Physical Uplink Control Channel，PUCCH)(例如：URLLC的PUCCH与eMBB PUCCH)资源上传输时，如何传输UCI是亟待解决的问题。
发明内容
本公开实施例的一个目的在于提供一种处理上行控制信息的方法及设备，解决承载在不同PUCCH资源上的UCI如何传输的问题。
依据本公开实施例的第一方面，提供了一种处理UCI的方法，所述方法 包括：

第二确定模块，用于如果所述第一PUCCH资源与所述第二PUCCH资源部分重叠，且所述第一UCI的优先级比所述第二UCI的优先级高，确定是否丢弃所述第二UCI。

在本公开实施例中，当有多个UCI分别承载在不同PUCCH资源上传输时，可以根据UCI的优先级保证高优先级的UCI的传输，从而可以保证高优先级业务的优先传输。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
本申请的说明书和权利要求书中的术语“包括”以及它的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外，说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一，例如A和/或B，表示包含单独A，单独B，以及A和B都存在三种情况。
在本公开实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本公开实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
本文所描述的技术不限于第五代移动通信(5th-generation，5G)系统以及后续演进通信系统。本文所描述的技术也不限于LTE/LTE的演进(LTE-Advanced，LTE-A)系统，并且也可用于各种无线通信系统，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。
术语“系统”和“网络”常被可互换地使用。CDMA系统可实现诸如CDMA2000、通用地面无线电接入(Universal Terrestrial Radio Access，UTRA)等无线电技术。UTRA包括宽带CDMA(Wideband Code Division Multiple Access，WCDMA)和其他CDMA变体。TDMA系统可实现诸如全球移动通信系统(Global System for Mobile Communication，GSM)之类的无线电技术。OFDMA系统可实现诸如超移动宽带(Ultra Mobile Broadband，UMB)、演进型UTRA(Evolution-UTRA，E-UTRA)、IEEE 802.11(Wi-Fi)、IEEE 802.16(WiMAX)、IEEE 802.20、Flash-OFDM等无线电技术。UTRA和E-UTRA是通用移动电信系统(Universal Mobile Telecommunications System，UMTS)的部分。LTE和更高级的LTE(如LTE-A)是使用E-UTRA的新UMTS版本。UTRA、E-UTRA、UMTS、LTE、LTE-A以及GSM在来自名为“第三代伙伴项目”(3rd Generation Partnership Project，3GPP)的组织的文献中描述。CDMA2000和UMB在来自名为“第三代伙伴项目2”(3GPP2)的组织的文献中描述。本文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。
下面结合附图介绍本公开的实施例。本公开实施例提供的处理上行控制信息的方法及设备可以应用于无线通信系统中。参考图2，为本公开实施例提供的一种无线通信系统的架构示意图。如图2所示，该无线通信系统可以包括：网络设备20和终端，终端记做用户设备(User Equipment，UE)21，UE11可以与网络设备20通信(传输信令或传输数据)。在实际应用中上述各个设备之间的连接可以为无线连接，为了方便直观地表示各个设备之间的连接关系，图2中采用实线示意。需要说明的是，上述通信系统可以包括多个UE21，网络设备20可以与多个UE21通信。
本公开实施例提供的终端可以为手机、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-Mobile Personal Computer，UMPC)、上网本或者个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device， MID)、可穿戴式设备(Wearable Device)或车载设备等。
本公开实施例提供的网络设备20可以为基站，该基站可以为通常所用的基站，也可以为演进型基站(evolved node base station，eNB)，还可以为5G系统中的网络设备(例如，下一代基站(next generation node base station，gNB)或发送和接收点(transmission and reception point，TRP))等设备。
参见图3，本公开实施例提供一种处理UCI的方法，该方法的执行主体可以为终端，具体步骤如下：
步骤301：确定第一PUCCH资源承载的第一UCI的优先级和第二PUCCH承载的第二UCI的优先级；
可选地，在步骤301中可以根据物理层信令或参数确定第一PUCCH资源承载的第一UCI的优先级和第二PUCCH承载的第二UCI的优先级，例如：根据下行控制信息(Downlink Control Information，DCI)格式、加扰DCI的无线网络临时标识(Radio Network Tempory Identity，RNTI)、DCI中调制与编码策略(Modulation and Coding Scheme，MCS)表等中的任意一项，确定不同PUCCH资源上承载的UCI的优先级。当然可以理解的是，本领域技术人员也可以采用其他类似方式确定不同PUCCH资源上承载的UCI的优先级。
在本公开实施例中，高优先级的UCI(包括：HARQ-ACK、SR、CSI)可以对应以下至少一项：
(1)一个特定的DCI格式；
例如，定义一个不同于相关技术中的下行链路(Down Link，DL)调度DCI载荷(回退DCI 1-0和标准(normal)DCI 1-1)的紧凑(compact)DCI，该DCI指示的PUCCH资源传输的UCI具有高优先级。当然可以理解的是，在本公开实施例中对特定的DCI格式不做具体限定。
(2)使用特定的RNTI加扰的DCI；
例如，特定的RNTI可以是调制与编码策略-小区无线网络临时标识(MCS-C-RNTI)。MCS-C-RNTI加扰的DCI中指示的PUCCH资源传输的UCI的优先级高于小区无线网络临时标识(Cell-Radio Network Temporary Identifier，C-RNTI)加扰的DCI中指示的PUCCH资源传输的UCI的优先级。当然可以理解的是，在本公开实施例中对特定的RNTI不做具体限定。
(3)DCI中MCS采用低频谱效率的MCS表(table)；
例如，低频谱效率的MCS表可以是MCS索引表3(MCS index table 3)，如果一个DCI中被配置使用MCS index table3，该DCI指示的PUCCH资源传输的UCI具有高优先级，高于采用其他MCS表的DCI指示的PUCCH资源传输的UCI的优先级，其他MCS表可以是MCS索引表1(index table 1)，如支持64相正交振幅调制(Quadrature Amplitude Modulation，QAM)或MCS索引表2(index table 2)，如支持256QAM。当然可以理解的是，在本公开实施例中对低频谱效率的MCS表不做具体限定。
在本公开实施例中，低优先级的UCI(包括HARQ-ACK、SR、CSI)可以对应以下至少一项：
(1)除了上述特定的DCI格式之外的其他DCI格式；
例如，其他DCI格式可以是相关技术中的DL调度DCI，例如：回退DCI1-0和normal DCI 1-1，当然并不限于此。
(2)使用除上述特定RNTI，其他RNTI加扰的DCI；
例如，其他RNTI可以是C-RNTI，当然并不限于此。
(3)DCI中MCS采用其他MSC表；
其他MSC表指除了低频谱效率的MCS表，可以是MCS索引表1或MCS索引表2。例如，根据DCI中MCS采用MCS索引表1或MCS索引表2，该DCI指示的PUCCH资源承载的UCI的优先级为低优先级。
步骤302：如果第一PUCCH资源与第二PUCCH资源部分重叠，且第一UCI的优先级比第二UCI的优先级高，确定是否丢弃第二UCI。
例如：第一UCI的优先级为高优先级，第二UCI的优先级为低优先级。
以图4为例，针对URLLC业务的PUCCH 1资源与针对eMBB业务的PUCCH 2资源部分重叠，PUCCH 1资源承载的UCI的优先级为优先级1，PUCCH 2资源承载的UCI的优先级为优先级2，其中优先级1高于优先级2，则在PUCCH 1上传输优先级1的UCI，丢弃优先级2的UCI，或者在PUCCH1上传输优先级1的UCI和优先级2的UCI，即将优先级2的UCI的至少部分内容和优先级1的UCI复用到PUCCH1资源上传输，由于URLLC业务通常具有更高的业务优先级，因此当PUCCH资源冲突处理时可以保证URLLC 业务的传输。
在本公开实施例中，当有多个UCI分别承载在不同PUCCH资源上传输时，可以根据UCI的优先级保证高优先级的UCI的传输，从而可以保证高优先级业务的优先传输。
参见图5，本公开实施例提供一种处理UCI的方法，该方法的执行主体可以为终端，具体步骤如下：
步骤501：确定第一PUCCH资源承载的第一UCI的优先级和第二PUCCH承载的第二UCI的优先级；
需要说明是时，步骤501与步骤301的内容相同，在此不再敷述。
步骤502：如果第一PUCCH资源与第二PUCCH资源部分重叠，且第一UCI的优先级比第二UCI的优先级高，根据第二UCI的类型，确定是否丢弃第二UCI。
在本公开实施例中，可选地，第二UCI的类型可以是以下任一项HARQ-ACK、SR、CSI。这样可以根据第二UCI是HARQ-ACK、SR、CSI中的任意一种类型，判断是丢弃该第二UCI还是将该第二UCI与第一UCI复用到第一PUCCH资源上传输。
在本公开实施例中，如果承载高优先级的UCI的PUCCH与承载低优先级的UCI的PUCCH重叠，按照UCI的类型确定是否丢弃低优先级的UCI。
在本公开实施例中，当有多个UCI分别承载在不同PUCCH资源上传输时，可以根据UCI的优先级保证高优先级的UCI的传输，从而可以保证高优先级业务的优先传输。同时，对于低优先级的UCI，能传输部分重要的UCI内容。
参见图6，本公开实施例提供一种处理UCI的方法，该方法的执行主体可以为终端，具体步骤如下：
步骤601：确定第一PUCCH资源承载的第一UCI的优先级和第二PUCCH承载的第二UCI的优先级，执行步骤602或步骤603；
需要说明是时，步骤601与步骤301的内容相同，在此不再敷述。
步骤602：如果第一PUCCH资源与第二PUCCH资源部分重叠，且第一UCI的优先级比第二UCI的优先级高，如果第二UCI的类型为HARQ-ACK 或者SR，确定不丢弃所述第二UCI，通过第一PUCCH资源传输第一UCI和第二UCI。
步骤603：如果第一PUCCH资源与第二PUCCH资源部分重叠，且第一UCI的优先级比第二UCI的优先级高，如果第二UCI的类型为CSI，丢弃第二UCI，通过第一PUCCH资源传输第一UCI。
在本公开实施例中，通过第一PUCCH资源传输第一UCI和第二UCI是指对第一UCI和第二UCI编码后，再通过第一PUCCH资源传输经过编码的第一UCI和第二UCI。
方式一：对第一UCI和第二UCI分别进行编码，按照时域顺序将经过编码的第一UCI和第二UCI映射到资源粒子(Resource Element，RE)上，其中第一UCI占用的资源粒子排列在第二UCI占用的资源粒子前面；然后通过第一PUCCH资源传输经过编码的第一UCI和第二UCI。可以理解是，上述资源粒子也可以称为资源单元。
示例性地，当复用两种优先级的UCI信息时，高优先级的UCI(例如HARQ-ACK)与低优先级的UCI(例如HARQ-ACK)分别编码。并且把高优先级的UCI(例如HARQ-ACK)占用的RE按照时域顺序排在前面，低优先级的UCI(例如HARQ-ACK)占用的RE按照时域顺序排在后面，一同在PUCCH上传输。
方式二：对第一UCI和所述第二UCI分别进行编码，并按照预定义的顺序将经过编码的第一UCI和第二UCI映射到资源粒子上；通过第一PUCCH资源传输经过编码的第一UCI和第二UCI。例如：预定义的顺序可以包括：第一UCI占用的RE在频域由高频率向低频率映射，第二UCI占用的RE在频域由低频率向高频率映射。
示例性地，如果高优先级的UCI(例如HARQ-ACK)占用的RE与低优先级的UCI占用的RE在相同符号上。按照预定义的顺序，例如高优先级的UCI(例如HARQ-ACK)占用的RE在频域由高频率向低频率映射，低优先级的UCI(例如HARQ-ACK)占用的RE在频域由低频率向高频率映射。
在本公开实施例中，如果承载高优先级的UCI的PUCCH与承载低优先级的UCI的PUCCH部分重叠，按照UCI的类型确定是否丢弃低优先级的 UCI。如果低优先级的UCI是HARQ-ACK或SR，把该低优先级的UCI与高优先级的UCI(例如HARQ-ACK)复用到高优先级的PUCCH传输；如果低优先级的UCI是CSI，丢弃低优先级的CSI，只传输承载高优先级的UCI(例如HARQ-ACK)的PUCCH。
在本公开实施例中，当有多个UCI分别承载在不同PUCCH资源上传输时，可以根据UCI的优先级保证高优先级的UCI的传输，从而可以保证高优先级业务的优先传输。同时，对于低优先级的UCI，能传输部分重要的UCI内容。
参见图7，本公开实施例提供一种处理UCI的方法，该方法的执行主体可以为终端，具体步骤如下：
步骤701：确定第一PUCCH资源承载的第一UCI的优先级和第二PUCCH承载的第二UCI的优先级；
需要说明是时，步骤701与步骤301的内容相同，在此不再敷述。
步骤702：如果第一PUCCH资源与第二PUCCH资源部分重叠，且第一UCI的优先级比第二UCI的优先级高，根据第二UCI的载荷，确定是否丢弃第二UCI。
在本公开实施例中，如果承载高优先级的UCI(例如HARQ-ACK)的PUCCH与承载低优先级的UCI(CSI、HARQ-ACK或SR)重叠，按照UCI的载荷确定是否丢弃低优先级的UCI信息。
在本公开实施例中，当有多个UCI分别承载在不同PUCCH资源上传输时，可以根据UCI的优先级保证高优先级的UCI的传输，从而可以保证高优先级业务的优先传输。
参见图8，本公开实施例提供一种处理UCI的方法，该方法的执行主体可以为终端，具体步骤如下：
步骤801：确定第一PUCCH资源承载的第一UCI的优先级和第二PUCCH承载的第二UCI的优先级，执行步骤802或步骤803；
需要说明是时，步骤801与步骤301的内容相同，在此不再敷述。
步骤802：如果第一PUCCH资源与第二PUCCH资源部分重叠，且第一UCI的优先级比第二UCI的优先级高，如果第二UCI的载荷小于预设值，确 定不丢弃所述第二UCI，通过第一PUCCH资源传输第一UCI和第二UCI；
需要说明的是，步骤802中的通过第一PUCCH资源传输第一UCI和第二UCI的方式与步骤602中的通过第一PUCCH资源传输第一UCI和第二UCI的方式相同，在此不再敷述。
步骤803：如果第一PUCCH资源与第二PUCCH资源部分重叠，且第一UCI的优先级比第二UCI的优先级高，如果第二UCI的载荷大于或等于预设值，丢弃第二UCI，通过第一PUCCH资源传输第一UCI。
在本公开实施例中，可选地，预设值可以由高层信令配置，或者可以由DCI指示，可以理解的是，对预设值的取值不做具体限定。
在本公开实施例中，可选地，与第一UCI对应的DCI中包括：UCI复用指示域，该UCI复用指示域指示是否允许在第一UCI中复用第二UCI的比特(bit)数。
在本公开实施例中，可选地，UCI复用指示域包括以下一项或多项：
第一指示信息，用于指示不允许在第一UCI中复用第二UCI；
第二指示信息，用于指示在第一UCI中复用第二UCI的比特数。
示例性地，如果预设值由DCI指示，可以在第一UCI相应的DCI中增加一个UCI复用指示域，指示允许复用的第二UCI的bit数，即在第一PUCCH上承载高优先级的第一UCI和低优先级的第二UCI的bit数。
表1：
码位(Code point) 允许复用低优先级的UCI的bit数
00 不允许复用
01 X1
10 X2
11 X3
其中，X1，X2，X3可以由高层信令配置。
进一步地，X1可以用于指示复用低优先级的SR的bit数。
X2可以用于指示复用低优先级的HARQ-ACK的bit数。
X3可以用于指示复用低优先级的CSI的bit数。
在本公开实施例中，如果承载高优先级的UCI(例如HARQ-ACK)的第一PUCCH与承载低优先级的UCI(例如CSI、HARQ-ACK或SR)的第二 PUCCH重叠，按照UCI的载荷确定是否丢弃低优先级的UCI信息。如果低优先级的UCI载荷小于预设值，把该UCI与高优先级的UCI(例如HARQ-ACK)中的至少部分内容复用到高优先级的第一PUCCH传输，否则，丢弃低优先级的UCI，只通过第一PUCCH传输高优先级的UCI(例如HARQ-ACK)。
在本公开实施例中，当有多个UCI分别承载在不同PUCCH资源上传输时，可以根据UCI的优先级保证高优先级的UCI的传输，从而可以保证高优先级业务的优先传输。同时，对于低优先级的UCI，能传输部分重要的UCI内容。
本公开实施例中还提供了一种终端，由于终端解决问题的原理与本公开实施例中处理上行控制信息的方法相似，因此该终端的实施可以参见方法的实施，重复之处不再敷述。
