Description

上行传输方法和装置
本申请要求于2020年4月10日提交中国专利局、申请号为202010281149.7、申请名称为“上行传输方法和装置”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
本申请涉及通信技术，尤其涉及一种上行传输方法和装置。
背景技术
当需要传输对时延和可靠性有较高要求的业务时，例如高可靠低时延通信(ultra reliable and low latency communications，URLLC)业务，终端设备向网络设备发送调度请求，网络设备要尽快为其调度合适的传输资源以满足该业务的时延需求。此时，如果网络设备已经把当前可用的资源调度给其他的一个或多个终端设备，用于传输对时延要求不高的业务，例如增强型移动宽带(enhanced mobile broadband，eMBB)业务，那么为了保证URLLC业务的低时延、高可靠性需求，网络设备可以将已调度的资源重新调度给传输URLLC业务的终端设备。
目前，网络设备为终端设备指示用于进行业务传输资源，但是由于同一个终端设备不同业务占用的资源互相重叠，造成高优先级业务被放弃，而低优先级业务优先传输的情况，从而导致业务质量无法保障的问题。
发明内容
本申请提供一种上行传输方法和装置，以避免高优先级业务被放弃，而低优先级业务优先传输的问题。
第一方面，本申请提供一种上行传输方法，该方法的执行主体可以是终端设备，也可以是应用于终端设备中的芯片。下面以执行主体是终端设备为例进行描述。包括终端设备确定第一时频资源和第一优先级，并接收第二时频资源的指示信息和第二优先级的指示信息。其中，所述第一时频资源用于第一上行传输，所述第一时频资源和所述第一优先级对应，所述第二时频资源和所述第二优先级对应；进而当所述第二优先级高于所述第一优先级，且所述第一时频资源和所述第二时频资源有重叠时，所述终端设备在所述第一时频资源的部分或全部时频资源上取消所述第一上行传输；或者，当所述第二优先级低于或等于所述第一优先级时，所述终端设备在所述第一时频资上进行所述第一上行传输。
本申请在终端设备间上行复用场景下，网络设备给终端设备发送UL CI的同时，给终端设备指示UL CI中的时频资源对应的小区级优先级，而且给终端设备调度上行传输时指示该上行传输的小区级优先级，通过这两个小区级优先级的比较，终端设备可以确定是否取消即将开始或正在进行的上行传输，避免高优先级业务被放弃，而低优先级业务优先传输的问题。另外，网络设备在每次发送UL CI时，都会给终端设备指示UL CI中的时频资源对应的小区级优先级，终端设备可以实时确定是否取消上行传输，灵活且准确的实现上行传输。
在一种可能的实现方式中，所述接收第二时频资源的指示信息和第二优先级的指示信息，包括：接收来自网络设备的上行取消指示UL CI，所述UL CI包括所述第二时频资源的指示信息和所述第二优先级的指示信息。
通过在UL CI中增加优先级指示域，网络设备可以在指示重新调度的时频资源的同时指示该时频资源重新被调度的上行传输的优先级，不必增加新的信令，实现UL CI动态指示小区级优先级的目的。
在一种可能的实现方式中，所述接收第二时频资源的指示信息和第二优先级的指示信息，包括：接收来自网络设备的UL CI和媒体接入控制控制元素MAC CE，所述UL CI包括所述第二时频资源的指示信息，所述MAC CE包括所述第二优先级的指示信息。

本申请涉及到的相关技术说明：
一、用户间上行复用机制
当终端设备需要传输对时延和可靠性有较高要求的业务时，例如URLLC业务，可以向网络设备发送调度请求，网络设备尽快为其调度合适的时频资源以满足URLLC业务的时延需求。如果此时网络设备已经把当前可用的时频资源调度给其它的一个或多个终端设备，用于传输对时延要求不高的业务，例如eMBB业务，那么为了保证URLLC业务的低时延、高可靠性需求，网络设备可以将已调度的时频资源重新调度给传输URLLC业务的终端设备。网络设备向传输eMBB业务的一个或多个终端设备发送上行取消指示(uplink cancellation indication，UL CI)，该UL CI指示了一个时频资源，该时频资源是网络设备即将调度给传输URLLC业务的终端设备的。传输eMBB业务的UE接收到该UL CI后，在相应的时频资源上取消即将开始或者正在进行中的eMBB业务传输。
由于网络设备即将调度给传输URLLC业务的终端设备的时频资源可能已经调度给一个或者多个终端设备，因此UL CI是可以发给一组终端设备的组公共(group common)下行控制信息(downlink control information，DCI)，即网络设备发送的一个UL CI可以通知一组终端设备在相应的资源上取消即将开始或者正在进行中的业务传输。采用group common DCI可以减少信令开销。
二、优先级
在物理层，一个终端设备可以支持两个终端设备级的优先级的上行业务传输，即在终端设备内，其传输的多个上行业务被分别配置了优先级系数(priority index)0(低优先级)或1(高优先级)。当终端设备的不同优先级的上行业务传输占用的物理层时频资源互相碰撞时，取消低优先级业务的传输，仅传输高优先级业务。
对于支持两个终端设备级的优先级的上行业务传输的终端设备，当收到UL CI时，如果即将开始或正在进行的上行业务传输所使用的时频资源和UL CI指示的时频资源有重叠区域，可以采用以下三种方法确定取消哪些优先级的业务传输：
1、取消被配置为低优先级的上行业务传输，即priority index＝0的上行业务。如果终端设备的上行业务没有被配置优先级，则默认为该终端设备的业务均为低优先级。
2、取消UL CI指示的时频资源上的所有上行传输。
3、通过无线资源控制(radio resource control，RRC)信令配置采用上述方法1或方法2。
而在一个小区内，所有终端设备支持的上行业务的优先级可能不止有两个。针对同一种上行业务，在不同的终端设备内，其被配置的优先级也可能不同。示例性的，表1示出了小区内接入的三个终端设备的终端设备级优先级和小区级优先级的对应关系的一个示例。
表1
Figure PCTCN2021086220-appb-000001
如表1所示，终端设备级优先级包括priority index＝0(低优先级)和priority index＝1(高优先级)两个优先级，小区级优先级包括四个优先级，其从低到高分别为priority1-priority4。终端设备1支持的两种上行业务的小区级优先级为priority1和priority2，其中priority1的业务被配置为终端设备级的低优先级priority index＝0，priority2的业务被配置为终端设备级的高优先级priority index＝1。终端设备2支持的两种上行业务的小区级优先级为priority2和priority3，其中priority2的业务被配置为终端设备级的低优先级priority index＝0，priority3的业务被配置为终端设备级的高优先级priority index＝1。终端设备3支持的两种上行业务的小区级优先级为priority1和priority4，其中priority1的业务被配置为终端设备级的低优先级priority index＝0，priority4的业务被配置为终端设备级的高优先级priority index＝1。可以看到，小区级优先级为priority2的上行业务，在终端设备1中被配置为高优先级，在终端设备2中被配置为低优先级。
因此针对终端设备来讲，其所支持的上行业务可能分别有两类优先级的配置，其中一类优先级对应于服务小区内所有终端设备所支持的全部业务优先级中的一个业务优先级或者服务小区内所有配置为需要检测UL CI的全部终端设备所支持的全部业务优先级中的一个业务优先级，简称为小区级优先级；另一类对应于该终端设备所支持的全部业务的优先级的一个业务优先级，简称为终端设备级优先级。
由此就显现出上述三种确定取消哪些优先级的业务传输的方法存在的问题：
方法1中终端设备取消被配置为低优先级的上行业务传输，不适用于只支持一种上行业务且上行业务没有被配置优先级的终端设备。因为该终端设备唯一支持的上行业务可能在整个小区内所对应的小区级优先级较高，但是在终端设备内被默认为低优先级业务，那么该上行业务在接收到UL CI时，很大可能需要取消唯一支持的上行业务传输。另外，收到的UL CI的终端设备，只要即将开始或正在传输的上行业务为低优先级，都面临需要取消该上行业务传输的操作。这两种情况都存在被取消的上行业务的小区级优先级高于UL CI所代表的终端设备的上行业务的小区级优先级。由此可见，方法1可能出现高优先级业务被放弃，而低优先级业务优先传输的情况。
方法2中不考虑终端设备即将开始或正在传输的上行业务的优先级，直接取消的操作，更有可能出现高优先级业务被放弃，而低优先级业务优先传输的情况。
方法3中通过RRC信令配置采用上述方法1或方法2，但RRC信令是半静态配置的，也就是说网络设备在发送UL CI、为终端设备调度上行传输之前就完成了该配置。因此很有可能网络设备在配置RRC信令参数时，并不知道未来可能发送的UL CI所代表的终端设备的上行业务的优先级和终端设备即将开始或正在传输的上行业务的优先级的关系，从而无法准确配置终端设备所采用的方法。而无论采用方法1还是采用方法2仍然存在上述问题。
本申请提供了一种上行传输方法，以解决上述相关技术中，收到UL CI的终端设备为了让路于UL CI中的业务传输，该终端设备需要放弃即将开始或正在进行的业务传输，从而导致的高优先级业务被放弃，而低优先级业务优先传输的问题。
如图1所示，为本申请实施例适用的一种可能的网络架构示意图，包括终端设备110和接入网设备120。终端设备110和接入网设备120间可通过空口进行通信，空口可以理解为终端设备和接入网设备之间的无线接口。空口的传输包括上行传输和下行传输。
示例的，上行传输指终端设备110向接入网设备120发送上行信息。其中，上行信息可包括上行数据信息、上行控制信息、参考信号(reference signal，RS)中的一个或多个。用于传输上行信息的信道称为上行信道，上行信道可以为物理上行共享信道(physical uplink shared channel，PUSCH)或物理上行控制信道(physical uplink control channel，PUCCH)。PUSCH用于承载上行数据，上行数据也可以称为上行数据信息。PUCCH用于承载终端设备反馈的上行控制信息(uplink control information，UCI)。UCI中可以包括信道状态信息(channel state information，CSI)、肯定应答(acknowledgement，ACK)/否定应答(negative acknowledgement，NACK)等。
示例的，下行传输指接入网设备120向终端设备110发送下行信息。下行信息可以包括下行数据信息、下行控制信息和下行参考信号中的一个或多个。下行参考信号可以为信道状态信息参考信号(channel state information reference signal，CSI-RS)或相位跟踪参考信号(phase tracking reference signal，PTRS)。用于传输下行信息的信道称为下行信道，下行信道可以为物理下行共享信道(physical downlink shared channel，PDSCH)或物理下行控制信道(physical downlink control channel，PDCCH)。所述PDCCH用于承载DCI，PDSCH用于承载下行数据，下行数据也可称为下行数据信息。
可选的，在图1所示的网络架构中，还可包括核心网设备130。其中，终端设备110可通过无线的方式与接入网设备120相连，接入网设备120可通过有线或无线的方式与核心网设备130相连。核心网设备130与接入网设备120可以是独立的不同的物理设备，或者，核网设备130与接入网设备120可以是相同的物理设备，该物理设备上集成有核心网设备130与接入网设备120的全部/部分逻辑功能。

图2为本申请上行传输方法实施例一的流程图，如图2所示，该过程200可以应用于图1所示的网络架构，该方法可以由终端设备和网络设备执行，或者也可以由终端设备中的芯片和网络设备中的芯片执行。图2中的网络设备可为上述图1中的接入网设备120，终端设备可为上述图1中的终端设备110。过程200可以以各种顺序执行和/或同时发生，不限于图2所示的执行顺序。本申请的上行传输方法包括：
步骤201、网络设备向终端设备发送第一时频资源的指示信息和第一优先级的指示信息。
第一时频资源是终端设备进行第一上行传输所使用的时频资源。第一上行传输是终端设备即将开始或正在进行的业务传输，该第一上行传输可以是由网络设备动态调度的PUSCH上的上行数据传输，也可以是由网络设备配置授权的PUSCH上的上行数据传输，还可以是信道探测信号(sounding reference signal，SRS)传输。该SRS可以是DCI激活的非周期SRS(aperiodic SRS，A-SRS)，也可以是MAC CE激活的半持续SRS(semi-persistent SRS，SP-SRS)，还可以是半静态配置的周期SRS(periodic SRS，P-SRS)。
第一优先级为上述相关技术中的小区级优先级，即该第一优先级对应于服务小区内所有终端设备所支持的全部业务优先级中的一个业务优先级或者服务小区内所有配置为需要检测UL CI的全部终端设备所支持的全部业务优先级中的一个业务优先级。
终端设备的第一上行传输作为一种业务传输被配置或指示了优先级。在终端设备内部该第一上行传输可以是高优先级或低优先级，在服务小区范围内该第一上行传输具有小区 级优先级。进行该第一上行传输所使用的第一时频资源和该第一上行传输的小区级优先级具有对应关系。可选的，该第一上行传输在终端设备内的优先级和该第一上行传输的小区级优先级具有对应关系。
在一种可能的实现方式中，网络设备可以向终端设备发送DCI，终端设备通过该DCI确定第一时频资源和第一优先级。该情况通常用于第一上行传输是动态调度的PUSCH上的上行数据传输和/或动态调度的SRS传输，网络设备根据终端设备的调度请求，给终端设备分配进行上行传输的时频资源，通过发送上行调度授权(uplink grant，UL grant)DCI将该时频资源的指示信息发送给终端设备，同时网络设备会在该DCI中携带终端设备请求的上行传输的小区级优先级的指示信息。终端设备基于该DCI中时频资源的指示信息和优先级的指示信息确定上述第一时频资源和第一优先级。
在一种可能的实现方式中，网络设备可以向终端设备发送DCI和第一高层信令，终端设备通过该DCI确定第一时频资源，通过该第一高层信令确定第一优先级。该情况通常用于第一上行传输是第二类配置授权的PUSCH上的上行数据传输或者半持续SRS传输，网络设备给终端设备预先配置进行上行传输的时频资源，通过发送UL grant的DCI将该时频资源的指示信息发送给终端设备。终端设备基于该DCI中时频资源的指示信息确定上述第一时频资源。对于配置授权的上行数据传输，网络设备可以通过高层信令配置上行传输的小区级优先级，该高层信令可以是RRC信令或媒体访问控制控制元素(medium access control control element，MAC CE)。一种方法是直接在高层信令中携带上行传输的小区级优先级，终端设备根据该高层信令确定上述第一优先级。另一种方法是在高层信令中携带配置授权的标识，而该配置授权的标识和小区级优先级之间具有对应关系，终端设备接收到该高层信令后，获取配置授权的标识，再基于配置授权的标识和小区级优先级之间的对应关系确定上述第一优先级。
在一种可能的实现方式中，网络设备可以向终端设备发送第二高层信令，终端设备通过该第二高层信令确定第一时频资源和第一优先级。该情况通常用于第一上行传输是第一类配置授权的PUSCH上的上行数据传输或者周期/半持续SRS传输，网络设备给终端设备预先配置进行上行传输的时频资源，通过高层信令将该时频资源的指示信息发送给终端设备，同时网络设备会在该高层信令中携带上行传输的小区级优先级，该高层信令可以是RRC信令或MAC CE。一种方法是直接在高层信令中携带上行传输的小区级优先级，终端设备根据该高层信令中的时频资源的指示信息和优先级的指示信息确定上述第一时频资源和第一优先级。另一种方法是在高层信令中携带配置授权的标识，而该配置授权的标识和小区级优先级之间具有对应关系，终端设备根据该高层信令中的时频资源的指示信息确定上述第一时频资源，获取配置授权的标识，再基于配置授权的标识和小区级优先级之间的对应关系确定上述第一优先级。
步骤202、网络设备向终端设备发送第二时频资源的指示信息和第二优先级的指示信息。
第二时频资源是网络设备在UL CI中指示的时频资源，如上所述该时频资源是网络设备已经调度给终端设备进行第一上行传输、但此时又打算重新调度给其它终端设备进行第二上行传输的时频资源。第二上行传输也可以是动态调度的PUSCH上的上行数据传输、配置授权的PUSCH上的上行数据传输或者SRS传输。
第二优先级同样为上述相关技术中的小区级优先级，即该第二优先级对应于服务小区内所有终端设备所支持的全部业务优先级中的一个业务优先级或者服务小区内所有配置为需要检测UL CI的全部终端设备所支持的全部业务优先级中的一个业务优先级。
进行该第二上行传输所使用的第二时频资源和该第二上行传输的小区级优先级也具有对应关系。本申请中网络设备向终端设备发送UL CI指示第二时频资源的同时，会指示与第二时频资源对应的第二优先级。
在一种可能的实现方式中，网络设备可以向终端设备发送UL CI，该UL CI包括第二时频资源的指示信息和第二优先级的指示信息。通过在UL CI中增加优先级指示域，网络设备可以在指示重新调度的时频资源的同时指示该时频资源重新被调度的上行传输的优先级，不必增加新的信令，实现UL CI动态指示小区级优先级的目的。
在一种可能的实现方式中，网络设备可以向终端设备发送UL CI和MAC CE，该UL CI包括第二时频资源的指示信息，该MAC CE包括第二优先级的指示信息。通过UL CI，网络设备可以指示重新调度的时频资源。网络设备在发送UL CI后可以触发一个MAC CE，在该MAC CE中网络设备携带指示优先级的指示信息，以指示重新调度的时频资源上进行的上行传输的优先级。这样可以不改变现有UL CI的格式，同时向该终端设备指示上述第二优先级，节省了UL CI的比特，而且通过MAC CE可以实现在MAC层指示终端设备优先级，终端设备在MAC层进行小区级优先级比较，如果发现MAC CE指示的对应于UL CI的优先级比即将开始或正在进行的第一上行传输的小区级优先级高，就可以不用下发数据包给物理层，从而减少物理层的信令开销。
这样即使终端设备不知道第二时频资源是要调度给哪一个其它终端设备，也不知道该第二时频资源重新被调度的上行传输的类型，但通过上述UL CI或者MAC CE，终端设备可以确定该第二时频资源被重新调度后对应的第二优先级，且该第二优先级是小区级优先级。
需要说明的是，上述步骤201和步骤202可以以各种顺序执行和/或同时发生，本申请对此不作具体限定。
步骤203、当第二优先级高于第一优先级，且第一时频资源和第二时频资源有重叠时，终端设备在第一时频资源的部分或全部时频资源上取消第一上行传输。
这里所说的第一时频资源中的至少部分时频资源，可以是第一时频资源中的部分时频资源，也可以是第一时频资源中的全部时频资源。
第二优先级高于第一优先级表示：UL CI指示的、或者UL CI触发的MAC CE指示的优先级高于第一上行传输的优先级；或者第二时频资源上传输的第二上行传输的小区级优先级高于第一时频资源上传输的第一上行传输的小区级优先级。
第一时频资源和第二时频资源有重叠包括：第一时频资源和第二时频资源在时域上包含相同的符号；或者，第一时频资源和第二时频资源在频域上包含相同的物理资源块或频带；或者，第一时频资源和第二时频资源在时域上包含相同的符号且在这些相同符号对应的频域上包含相同的物理资源块。
为了避免低优先级的上行传输对高优先级的上行传输造成干扰，终端设备可以取消重叠区域的第一上行传输，将时频资源让给优先级更高的第二上行传输。
在一种可能的实现方式中，当第一上行传输为PUSCH上的上行数据传输时，终端设 备可以从重叠区域的第一个符号开始取消第一上行传输，直到该PUSCH的最后一个符号。当第一上行传输为一个PUSCH重复副本(PUSCH repetition)的上行数据传输时，终端设备可以从重叠区域的第一个符号开始取消PUSCH重复副本的传输，直到该PUSCH重复副本的最后一个符号。
在一种可能的实现方式中，当第一上行传输为SRS传输时，终端设备可以取消SRS在重叠区域上的传输。
相应的，网络设备在第一时频资源的部分或全部时频资源上不接收第一上行传输。此时网络设备可以尝试在重叠区域上接收时频资源被重新调度的其它终端设备的第二上行传输。与第一上行传输类似，该第二上行传输可以是由网络设备动态调度的PUSCH上的上行数据传输，也可以是由网络设备配置授权的PUSCH上的上行数据传输，还可以是SRS传输。该SRS可以是DCI激活的A-SRS，也可以是MAC CE激活的SP-SRS，还可以是半静态配置的periodic SRS，P-SRS。
可以理解的是，网络设备接收上行传输包括对上行传输中的数据进行解调、混合自动重传请求(Hybrid Automatic Retransmission Qequest，HARQ)合并和译码等步骤；对应的，网络设备在部分时频资源上不接收上行传输可以理解为网络设备对该部分时频资源上接收到的信息不进行解调、HARQ合并以及译码。
在一种可能的实现方式中，当第一上行传输为PUSCH上的上行数据传输时，网络设备可以从重叠区域的第一个符号开始不接收第一上行传输，直到该PUSCH的最后一个符号。当第一上行传输为一个PUSCH重复副本(PUSCH repetition)的上行数据传输时，网络设备可以从重叠区域的第一个符号开始不接收PUSCH重复副本的传输，直到该PUSCH重复副本的最后一个符号。
在一种可能的实现方式中，当第一上行传输为SRS传输时，网络设备可以不接收SRS在重叠区域上的传输。该重叠区域是指第一时频资源和第二时频资源在时域上包含的相同的符号、在这些相同符号对应的频域上包含的相同的物理资源块。
上述描述是第一优先级只有一个时，终端设备和网络设备对优先级进行判断的流程。
在一种可能的实现方式中，当终端设备确定的第一优先级包括至少两个时，第二优先级高于第一优先级是指第二优先级高于至少两个第一优先级中的最高优先级。即第二时频资源上传输的第二上行传输的小区级优先级高于第一时频资源上传输的第一上行传输的最高小区级优先级。该情况下至少两个第一优先级可以组成一个优先级集合，即终端设备被配置的第一优先级是一个优先级集合，其中包括至少两个优先级，那么第二优先级高于第一优先级是指第二优先级高于优先级集合中的最高优先级。
在一种可能的实施方式中，终端设备确定的第一优先级的数量至少有两个，这是由于优先级是指业务的优先级，而业务和MAC层的逻辑信道一一对应，多个逻辑信道可以对应于一个物理信道，因此在第一时频资源上进行的上行传输可能对应多个逻辑信道，进而该第一时频资源对应多个优先级。
在一种可能的实现方式中，如果终端设备是通过MAC CE获取第二优先级，并确定第二优先级高于或等于第一优先级，此时如果物理层的PUSCH还没开始发送，终端设备将不再创建与第一上行传输相关的数据包，也就不会向物理层发送MAC协议数据单元(protocol data unit，PDU)；如果物理层的PUSCH已经开始发送，终端设备已经将与第 一上行传输相关的MAC PDU发送给物理层，终端设备可以通过MAC层与物理层之间的消息指示物理层取消相关传输。
本申请在终端设备间上行复用场景下，网络设备给终端设备发送UL CI的同时，给终端设备指示UL CI中的时频资源对应的小区级优先级，而且给终端设备调度上行传输时指示该上行传输的小区级优先级，通过这两个小区级优先级的比较，终端设备可以确定是否取消即将开始或正在进行的上行传输，避免高优先级业务被放弃，而低优先级业务优先传输的问题。另外，网络设备在每次发送UL CI时，都会给终端设备指示UL CI中的时频资源对应的小区级优先级，终端设备可以实时确定是否取消上行传输，灵活且准确的实现上行传输。
图3为本申请上行传输方法实施例二的流程图，如图3所示，该过程300可以应用于图1所示的网络架构，该方法可以由终端设备和网络设备执行，或者也可以由终端设备中的芯片和网络设备中的芯片执行。图3中的网络设备可为上述图1中的接入网设备120，终端设备可为上述图1中的终端设备110。过程300可以以各种顺序执行和/或同时发生，不限于图3所示的执行顺序。本申请的上行传输方法包括：
步骤301、网络设备向终端设备发送第一时频资源的指示信息和第一优先级的指示信息。
步骤301和上述步骤201的技术原理类似，此处不再赘述。
步骤302、网络设备向终端设备发送第二时频资源的指示信息和第二优先级的指示信息。
步骤302和上述步骤202的技术原理类似，此处不再赘述。
需要说明的是，上述步骤301和步骤302可以以各种顺序执行和/或同时发生，本申请对此不作具体限定。
步骤303、当第二优先级低于或等于第一优先级时，终端设备在第一时频资上进行第一上行传输。
第二优先级低于或等于第一优先级表示：第二时频资源上传输的第二上行传输的小区级优先级低于或等于第一时频资源上传输的第一上行传输的小区级优先级。
为了避免低优先级的上行传输对高优先级的上行传输造成干扰，终端设备可以不用理会UL CI，仍然进行第一上行传输。
相应的，网络设备在第一时频资源上接收第一上行传输。第一优先级和第二优先级是由网络设备通过DCI或者高层信令指示给终端设备的，因此网络设备可以确定第一优先级和第二优先级的关系。网络设备在确定第二优先级低于或等于第一优先级时，将确定终端设备会仍然进行第一上行传输，而自己也可以通过第一时频资源接收第一上行传输。
上述描述是第一优先级只有一个时，终端设备和网络设备对优先级进行判断的流程。
在一种可能的实现方式中，当终端设备确定的第一优先级包括至少两个时，第二优先级低于或等于第一优先级表示是指第二优先级低于或等于至少两个第一优先级中的最高优先级。即第二时频资源上传输的第二上行传输的小区级优先级低于或等于第一时频资源上传输的第一上行传输的最高小区级优先级。
本申请中当第二优先级等于第一优先级时，可以采用步骤203的方法，终端设备在第一时频资源的部分或全部时频资源上取消第一上行传输，网络设备在第一时频资源的部分 或全部时频资源上不接收第一上行传输；也可以采用步骤303的方法，终端设备在第一时频资上进行第一上行传输，网络设备在第一时频资源上接收第一上行传输。本申请对于这种情况不作具体限定。
图2和图3所示的方法实施例中，考虑到占用相同时频资源的多个上行传输可能来自多个终端设备，因此在比较优先级时需要采同一标准或类型的优先级，而上述优先级介绍中，终端设备内的高优先级和低优先级是终端设备级优先级，只能用于终端设备内部的业务比较，同一种业务可能在不同的终端设备内被配置为不同的终端设备级优先级。只有小区级优先级才是服务小区内所有终端设备所支持的全部业务优先级中的业务优先级或者服务小区内所有配置为需要检测UL CI的全部终端设备所支持的全部业务优先级中的业务优先级，因此上述第一优先级和第二优先级均是小区级优先级。
本申请中网络设备针对接入的终端设备可以分别配置第一类优先级和第二类优先级的对应关系，第一类优先级是小区级优先级，第二类优先级是指终端设备内的高优先级或低优先级。一个第二类优先级对应一个或多个第一类优先级。网络设备可以根据第三高层信令配置第一优先级和第二优先级的对应关系，该第三高层信令可以是RRC信令或MAC CE。
示例性的，表2示出了小区内接入的四个终端设备的终端设备级优先级和小区级优先级的对应关系的另一个示例。
表2
Figure PCTCN2021086220-appb-000002
如表2所示，终端设备级优先级包括priority index＝0(低优先级)和priority index＝1(高优先级)两个优先级，小区级优先级包括四个优先级，其从低到高分别为priority1-priority4。终端设备1支持的两种上行业务中，低优先级priority index＝0对应priority1，高优先级priority index＝1对应priority2。终端设备2支持的两种上行业务中，低优先级priority index＝0对应priority2，高优先级priority index＝1对应priority3。终端设备3支持的两种上行业务中，低优先级priority index＝0对应priority1，高优先级priority index＝1对应priority4。终端设备4支持一种上行业务，没有被配置高优先级或低优先级，其小区级优先级为priority3。该示例中，终端设备内的优先级和小区级优先级是一对一的对应关系。
示例性的，表3示出了小区内接入的三个终端设备的终端设备级优先级和小区级优先级的对应关系的另一个示例。
表3
Figure PCTCN2021086220-appb-000003
如图3所示，终端设备级优先级包括priority index＝0(低优先级)和priority index＝1(高优先级)两个优先级，小区级优先级包括八个优先级，其从低到高分别为priority1-priority8。终端设备1支持的四种上行业务中，低优先级priority index＝0对应priority1和priority2，高优先级priority index＝1对应priority3和priority4。终端设备2支持的七种上行业务中，低优先级priority index＝0对应priority1、priority3和priority4，高优先级priority index＝1对应priority5、priority6、priority7和priority8。终端设备3支持两种上行业务，没有被配置高优先级或低优先级，其小区级优先级分别为priority6和priority7。该示例中，终端设备内的优先级和小区级优先级是一对多的对应关系。
在一种可能的实现方式中，网络设备也可以单独配置终端设备的第一类优先级和第二类优先级，而不建立第一类优先级和第二类优先级之间的对应关系。
本申请在终端设备间上行复用场景下，网络设备给终端设备发送UL CI的同时，给终端设备指示UL CI中的时频资源对应的小区级优先级，而且给终端设备调度上行传输时指示该上行传输的小区级优先级，通过这两个小区级优先级的比较，终端设备可以确定是否取消即将开始或正在进行的上行传输，避免高优先级业务被放弃，而低优先级业务优先传输的问题。另外，网络设备在每次发送UL CI时，都会给终端设备指示UL CI中的时频资源对应的小区级优先级，终端设备可以实时确定是否取消上行传输，灵活且准确的实现上行传输。
