具体实施方式
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，以及不限于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一种处理方法 及设备可以应用于无线通信系统中。参考图1，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1所示，该无线通信系统可以包括：网络设备10和终端11，终端11可以记做UE11，终端11可以与网络设备10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1中采用实线示意。
本公开实施例提供的网络设备10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。
本公开实施例提供的终端11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。
参见图2，本公开实施例提供一种上行传输的方法，该方法的执行主体可以为支持多种业务的终端，可能既有低优先级的业务，同时又有高优先级的业务，具体步骤如下：
步骤201：接收第一PUSCH对应的取消指示信息和第二PUSCH的调度授权，第一PUSCH的优先级低于第二PUSCH的优先级；
其中，第二PUSCH相当于高优先级(high priority)的PUSCH，第一PUSCH相当于低优先级的PUSCH。可以理解的是，在本公开实施例中PUSCH的优先级可以根据物理层参数确定，例如对于调度PUSCH的下行控制信息(Downlink Control Information，DCI)，或者网络配置的物理层参数确定。
例如，终端根据网络侧设备发送的DCI确定待发送的物理上行信道相应的业务，该DCI为该待发送的物理上行信道对应的DCI。
若DCI的格式为特定的DCI载荷大小，或者DCI采用特定无线网络临时标识(Radio Network Temporary Identifier，RNTI)加扰，比如调制编码方式-小区无线网络临时标识(Modulation Coding Scheme-Cell-Radio Network Temporary Identifier，MCS-C-RNTI)，或者DCI中优先级指示域指示为高优先级，则确定待发送的物理上行信道相应于高优先级PUSCH，例如URLLC 业务。
若DCI的格式不是特定的DCI载荷大小，或者DCI未采用特定RNTI加扰，或者DCI中优先级指示域指示为低优先级，则确定待发送的物理上行信道相应于低优先级PUSCH，例如eMBB业务。
可选地，取消指示(Cancelation Indicator，CI)信息指示的时频资源至少与第一PUSCH的时频资源重叠，其中，取消指示信息还可以称为取消指示CI。
步骤202：根据取消指示信息和调度授权的时域位置，执行相应的终端行为。
在一些实施方式中，取消指示信息和调度授权的时域位置的关系可以包括：(1)取消指示信息的时域位置在调度授权的时域位置之前，(2)调度授权的时域位置在取消指示信息的时域位置之前。可选地，取消指示信息和调度授权的时域位置的关系不同，终端可执行不同的行为。终端先接收到调度授权后接收到CI信息时执行的行为，可能与终端先接收到CI信息再接收到调度授权时的行为不一致。
在一些实施方式中，终端行为的包括以下一项：
(1)复用第一PUSCH和第二PUSCH，这样可以确保该终端的高优先级业务的处理；
(2)在第一PUSCH和第二PUSCH复用后的时频资源与取消指示信息指示的时频资源重叠的情况下，取消(cancel)该取消指示信息所指示的时频资源上的传输，这样可以确保网络中其他终端的高优先级业务的处理；
(3)取消第一PUSCH的传输，这样可以确保该终端的第二PUSCH的传输，即确保该终端的高优先级业务的处理；
(4)在第二PUSCH的时频资源与取消指示信息指示的时频资源重叠的情况下，取消第一PUSCH和所述第二PUSCH的传输，这样可以确保网络中其他终端的高优先级业务的处理。
可以理解的是，对于取消第二PUSCH的传输可以是第二PUSCH的部分传输，也可以是第二PUSCH的全部传输，如果第二PUSCH在取消指示信息指示的时频资源以外的其他位置仍有解调参考信号(Demodulation Reference Signal， DMRS)，终端仍可以传输第二PUSCH除取消指示信息指示的时频资源以外的其他时频资源的PUSCH。
在一些实施方式中，在接收第一PUSCH对应的取消指示信息的步骤之前，还包括：接收调度第一PUSCH的PDCCH；相应地，接收第一PUSCH对应的取消指示信息的步骤包括：在PDCCH调度的第一PUSCH发送之前，接收第一PUSCH对应的取消指示信息。
即，接收第一PUSCH对应的取消指示信息和第二PUSCH的调度授权的时间是：在接收调度第一PUSCH的PDCCH之后，且在该PDCCH调度的PUSCH发送之前。
在一些实施方式中，根据所述取消指示信息和所述调度授权的时域位置，执行相应的终端行为的步骤，包括：
在所述调度授权的时域位置位于所述取消指示信息的时域位置之前的情况下，复用所述第一PUSCH和所述第二PUSCH。可以理解的是，在本公开实施例中复用第一PUSCH和第二PUSCH可以采用相关技术中的资源复用规则进行复用。
在一些实施方式中，所述调度授权的时域位置位于所述取消指示信息的时域位置之前是指：接收所述调度授权的PDCCH的最后的符号在接收所述取消指示信息的PDCCH的最后的符号之前。
在一些实施方式中，执行相应的终端行为的步骤，还包括：
在复用的时频资源与所述取消指示信息指示的时频资源重叠的情况下，取消所述取消指示信息所指示的时频资源上的传输。
具体实施方式为，取消该取消指示信息所指示的时频资源中与所述复用的时频资源的重叠资源上的传输。
参见图3，取消指示信息指示的时频资源与低优先级的PUSCH的时频资源部分重叠，低优先级的PUSCH的时频资源复用到高优先级的PUSCH的时频资源，取消复用后的时频资源的传输，这样可以确保网络中其他终端的高优先级业务的处理。
在一些实施方式中，根据所述取消指示信息和所述调度授权的时域位置，执行相应的终端行为的步骤，包括：
在所述取消指示信息的时域位置位于所述调度授权的时域位置之前的情况下，执行以下终端行为中的一种：(1)取消所述第一PUSCH的传输；(2)取消所述取消指示信息所指示的时频资源上的传输。
在一些实施方式中，所述取消指示信息的时域位置位于所述调度授权的时域位置之前是指：接收所述调度授权的PDCCH的最后的符号在接收所述取消指示信息的PDCCH的最后的符号之后。
在一些实施方式中，取消所述第一PUSCH的传输的步骤，包括：
在所述第二PUSCH的时频资源与所述取消指示信息指示的时频资源未重叠的情况下，取消所述第一PUSCH的传输；或者，在所述第二PUSCH的时频资源与所述取消指示信息指示的时频资源重叠的情况下，取消所述第一PUSCH的传输，并进行所述第二PUSCH的传输，其中，取消第一PUSCH的传输可以包括：仅取消第一PUSCH在重叠资源上的传输，或者，取消第一PUSCH的全部传输。进行第二PUSCH的传输包括：在重叠资源上进行第二PUSCH的传输。
参见图4，取消指示信息指示的时频资源与低优先级的PUSCH的时频资源重叠，与高优先级的PUSCH的时频资源不重叠，则取消低优先级的PUSCH的传输，进行高优先级的PUSCH的传输，这样可以确保该终端高优先级的PUSCH的传输。
参见图5，取消指示信息指示的时频资源与低优先级的PUSCH的时频资源重叠，与高优先级的PUSCH的时频资源重叠，则只取消低优先级PUSCH的传输，不取消高优先级的PUSCH的传输，这样可以确保该终端高优先级的PUSCH的传输。
在一些实施方式中，取消所述取消指示信息所指示的时频资源上的传输的步骤，包括：
在所述第二PUSCH的时频资源与所述取消指示信息指示的时频资源重叠的情况下，取消所述第一PUSCH和所述第二PUSCH的传输。其中，取消第一PUSCH的传输可以包括：仅取消第一PUSCH在重叠资源上的传输，或者，取消第一PUSCH的全部传输。取消第二PUSCH的传输可以包括：仅取消第二PUSCH在重叠资源上的传输，或者，取消第二PUSCH的全部传输。
参见图6，取消指示信息指示的时频资源与低优先级的PUSCH的时频资源重叠，与高优先级的PUSCH的时频资源重叠，则根据取消指示信息取消低优先级的PUSCH的传输和高优先级的PUSCH的传输，这样可以确保网络中其他终端的高优先级业务的处理。
在一些实施方式中，在步骤201之前或之后，图2所示的方法还包括：接收第一信息，所述第一信息指示：在所述终端的第二PUSCH的时频资源与取消指示的时频资源重叠的情况下，所述终端是否取消所述第二PUSCH的传输。
例如，终端通过无线资源控制(Radio Resource Control，RRC)信令接收第一信息。
例如：第一信息包括指示比特，“1”指示终端取消第二PUSCH的传输。“0”指示终端不取消第二PUSCH的传输，当然在本公开实施例中对第一信息的内容不做具体限定。
示例性地，当其他终端的PUSCH的优先级比该终端的第二PUSCH的优先级高，则网络侧通过第一指示信息指示该终端取消第二PUSCH的传输，确保其他终端的PUSCH的传输。
在一些场景中，对于同时支持多种业务的终端，可能既有低优先级的业务，同时又有高优先级的业务，在另一些场景中网络中其他终端的高优先级业务的优先级可能高于该终端的高优先级业务的优先级，均可以通过上述实施例确保高优先级的业务的处理。
在本公开实施例中，完善了在终端接收到高优先级的PUSCH的调度授权和取消指示信息之后的处理流程，可以确保高优先级业务得到优先处理，有效提高了无线通信系统通信的及时性和可靠性。
参见图7，本公开实施例还提供一种处理方法，该方法的执行主体为网络设备，具体步骤包括：
步骤701：发送第一PUSCH对应的取消指示信息，所述取消指示信息指示的时频资源与第一PUSCH与第二PUSCH复用后的时频资源不重叠；和/或，所述取消指示信息指示的时频资源与第二PUSCH的时频资源不重叠；其中，所述第一PUSCH的优先等级低于第二PUSCH的优先级，即，第二PUSCH相当 于高优先级的PUSCH，第一PUSCH相当于低优先级的PUSCH。或者，取消指示信息指示的时频资源可以与第一PUSCH和第二PUSCH复用后的时频资源重叠；和/或，所述取消指示信息指示的时频资源可以与第二PUSCH的时频资源重叠。
可选地，取消指示信息指示的时频资源至少与第一PUSCH的时频资源重叠。
在发明实施例中，网络侧通过发送该取消指示信息，该取消指示信息指示的时频资源不与终端的第二PUSCH的时频资源冲突，确保该终端的第二PUSCH的传输。
在一些实施方式中，在步骤701之前或之后，图7所示的方法还包括：
向终端发送第一信息，所述第一信息指示：在所述终端的第二PUSCH的时频资源与取消指示信息指示的时频资源重叠的情况下，所述终端是否取消所述第二PUSCH的传输。例如：通过RRC信令向所述终端发送所述第一信息。
例如：第一信息包括指示比特，“1”指示终端取消第二PUSCH的传输。“0”指示终端不取消第二PUSCH的传输，当然在本公开实施例中对第一信息的内容不做具体限定。
示例性地，当其他终端的PUSCH的优先级比该终端的第二PUSCH的优先级高，则网络侧通过第一指示信息指示该终端取消第二PUSCH的传输，确保其他终端的PUSCH的传输。
下面结合具体示例介绍在UE收到高优先级的PUSCH的调度授权与包含CI的DCI之后的处理流程。
示例1：
网络设备(例如基站(gNB)在调度一个eMBB的PUSCH后，有高优先级的业务到达，例如：可能是该UE的高优先级业务到达，然后其他UE的高优先级业务到达。如果该UE先接收高优先级的PUSCH的调度授权，即接收取消指示的PDCCH是最后的符号(last symbols)，则该UE先进行其高优先级的信道/信号的时频资源与低优先级的信道/信号的时频资源复用(例如UCI信息的复用)，如果复用后的信道/信号的时频资源仍然与CI指示的时频资源重叠，则可以执行A或B；
A：UE按照CI，取消复用后的信道/信号(例如高优先级的PUSCH)的传输，此时UE认为CI具有更高的优先级，这样可以确保其他UE的高优先级业务。
B：UE不期望CI指示的时频资源与复用后的信道/信号(例如高优先级的PUSCH)重叠，这样可以确保该UE的高优先级的PUSCH的传输。
参见图8，eMBB PUSCH的时频资源与URLLC PUSCH的时频资源复用，CI指示的时频资源与复用后的时频资源部分重叠，按照CI，取消复用后的时频资源的传输(例如，取消URLLC PUSCH的传输)，这样可以确保网络中其他终端的高优先级业务。
示例2：
gNB在调度一个eMBB的PUSCH后，有高优先级的业务到达，例如可能是其他UE的高优先级业务到达，然后又有该UE的高优先级业务到达。
如果该UE的高优先级的PUSCH的调度授权后接收，即接收高优先级的PUSCH的调度授权的PDCCH是last symbols，执行C或D；
其中，C：如果UE高优先级的PUSCH的时频资源与CI指示的时频资源不重叠，则UE cancel低优先级的PUSCH的传输，发送高优先级的PUSCH。
参见图9，URLLC PUSCH的时频资源与CI指示的时频资源不重叠，取消eMBB PUSCH的传输，进行URLLC PUSCH的传输。
D：如果CI指示的时频资源与该UE高优先级的PUSCH的时频资源重叠，CI指示的时频资源与eMBB PUSCH的时频资源重叠，则可以执行D1、D2或D3；
其中，D1：UE按照CI，只取消低优先级的PUSCH的传输，不取消高优先级的PUSCH的传输。
D2：UE取消低优先级的PUSCH的传输，不期望CI与其高优先级的PUSCH重叠。
D3：UE按照CI，可以取消低优先级和高优先级的PUSCH的传输，此时UE认为CI具有更高的优先级。
参见图10，URLLC PUSCH的时频资源与CI指示的时频资源重叠，取消eMBB PUSCH的传输。或者，按照CI，可以取消URLLC PUSCH的传输 和eMBB PUSCH的传输，此时UE认为CI具有更高的优先级，这样可以确保网络中其他终端的高优先级业务得到优先处理。
参见图11，本公开实施例还提供一种终端，该终端1100包括：
接收模块1101，用于接收第一PUSCH对应的取消指示信息和第二PUSCH的调度授权，第一PUSCH的优先级低于第二PUSCH的优先级；
其中，第二PUSCH相当于高优先级的PUSCH，第一PUSCH相当于低优先级的PUSCH。可选地，取消指示信息指示的时频资源至少与第一PUSCH的时频资源重叠。
处理模块1102，用于根据取消指示信息和所述调度授权的时域位置，执行相应的终端行为。
在一些实施方式中，接收模块1101进一步用于：在接收第一PUSCH对应的取消指示信息之前，接收调度第一PUSCH的PDCCH；在PDCCH调度的第一PUSCH发送之前，接收第一PUSCH对应的取消指示信息。
即，接收第一PUSCH对应的取消指示信息和第二PUSCH的调度授权的时间是：在接收调度第一PUSCH的PDCCH之后，且在该PDCCH调度的PUSCH发送之前。
在一些实施方式中，处理模块1102进一步用于：在所述调度授权的时域位置位于所述取消指示信息的时域位置之前的情况下，复用所述第一PUSCH和所述第二PUSCH。
可以理解的是，在本公开实施例中复用第一PUSCH和第二PUSCH可以采用的资源复用规则进行复用。
在一些实施方式中，所述调度授权的时域位置位于所述取消指示信息的时域位置之前是指：接收所述调度授权的PDCCH的最后的符号在接收所述取消指示信息的PDCCH的最后的符号之前。
在一些实施方式中，处理模块1102还用于：在第一PUSCH和第二PUSCH复用的时频资源与所述取消指示信息指示的时频资源重叠的情况下，取消所述取消指示信息所指示的时频资源上的传输。具体地，取消所述取消指示信息所指示的时频资源中与所述复用的时频资源的重叠资源上的传输。

在一些实施方式中，所述取消指示信息的时域位置位于所述调度授权的时域位置之前是指：接收所述调度授权的PDCCH的最后的符号在接收所述取消指示信息的PDCCH的最后的符号之后。
在一些实施方式中，处理模块1102进一步用于：在所述第二PUSCH的时频资源与所述取消指示信息指示的时频资源未重叠的情况下，取消所述第一PUSCH的传输；或者，在所述第二PUSCH的时频资源与所述取消指示信息指示的时频资源重叠的情况下，取消所述第一PUSCH的传输，并进行所述第二PUSCH的传输。
在一些实施方式中，处理模块1102进一步用于：在所述第二PUSCH的时频资源与所述取消指示信息指示的时频资源重叠的情况下，取消所述第一PUSCH和所述第二PUSCH的传输。
注意，在这种情况下，对于取消第二PUSCH的传输可以是第二PUSCH的部分传输，也可以是第二PUSCH的全部传输，如果第二PUSCH在取消指示信息指示的时频资源以外的其他位置仍有DMRS，终端仍可以传输第二PUSCH除取消指示信息指示的时频资源以外的其他时频资源的PUSCH。
在一些实施方式中，在图11所示的基础上，接收模块1101还用于：接收第一信息，所述第一信息指示：在所述终端的第二PUSCH的时频资源与取消指示的时频资源重叠的情况下，所述终端是否取消所述第二PUSCH的传输。
