Description

用户设备、基站及其方法 技术领域
本公开涉及无线通信技术领域，更具体地，本公开涉及用户设备、基站及其方法。
背景技术
2019年3月，在第三代合作伙伴计划(3rd Generation Partnership Project：3GPP)RAN#83次全会上批准了一个支持NR工业物联网的工作项目(参见非专利文献：RP-190728：New WID：Support of NR Industrial Internet of Things(IoT))。在工业应用场景中，用户设备(UE)需要同时处理来自不同应用或设备的数据流(traffic flows)，因此需要考虑用户设备内(intra-UE)发生上行/下行数据信道与控制信道发生冲突时优先级处理和/或复用，以及动态调度(grant)和配置调度之间以及两个或多个配置调度之间发生资源冲突的处理。据此，该工作项目的目的之一是在解决动态调度和配置调度之间以及两个或多个配置调度之间发生资源冲突方面进行增强，如果在媒体访问控制MAC(Medium Access Control)处理调度优先级，3GPP第二工作组(RAN2)需定义基于逻辑信道(LCH)优先级和逻辑信道优先级(LCP)限制的物理上行共享信道PUSCH(Physical Uplink Shared CHannel)调度优先级处理机制。
在2019年4月召开的3GPP RAN2#105bis次会议上达成：当配置多个配置上行调度CG(Configured Uplink Grant)或下行半静态调度SPS(Semi-Persistent Scheduling)时，为每个CG或SPS配置一个用于计算混合自动重传请求HARQ(Hybrid Automatic Repeat reQuest)进程号的偏移。该结论的目的在于将不同的配置上行调度(或下行SPS)映射到不同的HARQ进程，使得配置上行调度(或下行SPS)所关联或映射或使用的HARQ进程不同或没有重叠。在2019年5月召开的3GPP RAN2 #106次会议上达成：对于低优先级PUSCH的动态调度，UE将其对应的低优先级的MAC  PDU存储在HARQ缓存区中，使得gNB可以利用同一HARQ进程调度重传(For de-prioritized PUSCH on dynamic grant，the UE should store the de-prioritized MAC PDU in the HARQ buffer，to allow gNB to schedule re-transmission using the same HARQ process)；对于低优先级PUSCH的配置上行调度，a)UE将其对应的低优先级的MAC PDU存储在HARQ缓存区中，使得gNB可以调度重传，b)UE是否可以在随后的无线资源上进行重传是需要进一步讨论，例如采用随后关联到同一HARQ进程的无线资源(For de-prioritized PUSCH on configured grants，a)the UE could store the de-prioritized MAC PDU in the HARQ buffer，to allow gNB to schedule re-transmission.b)FFS if the UE could transmit it using the subsequent radio resources e.g.associated with the same HARQ proces)；上述结论至少适用于MAC实体已经为低低优先级的动态调度或配置上行调度产生了MAC PDU的情况。
基于上述达成的结论，当较低优先级MAC PDU存储在HARQ缓存区中，此时有上行调度可用(可以是动态调度或配置调度)，并且此上行调度不能用来传输缓存区中的MAC PDU。此时，UE如何处理所述可用的上行调度是需要考虑的问题。图1给出了此问题的示例描述，在T1，不同HARQ进程的动态调度DG1和配置调度CG发生冲突，动态调度的优先级更高，为配置调度CG生成的MAC PDU存储在缓存区中。在T2，接收到动态调度DG2且DG2与配置调度CG具有相同的HARQ进程，此时，因为为CG产生的MAC PDU还存储在对应HARQ进程的缓存区中，当DG2的优先级比CG低时，是否为DG2产生MAC PDU来覆盖缓存区中的MAC PDU？此外，当UE具有多个可用的上行调度且这些上行调度之间存在PUSCH持续时间重叠时如何选择一个上行调度来发送数据是需要考虑的问题。
发明内容
为了解决上述问题中的至少一部分，本发明提供了一种用户设备、基站及其方法，能够通过设置使能优先级指示标识来解决不同HARQ进程DG/CG PUSCH冲突、不同HARQ进程CG/CG冲突和相同HARQ进程上行调度/MAC PDU冲突。
为了实现上述目的，根据本发明，提出了一种由用户设备UE执行的方法，包括：针对接收到的上行调度识别与所述上行调度相对应的混合自动重传请求HARQ进程；判断所述上行调度用于新传还是用于重传；在判断为所述上行调度用于新传的情况下，则对于物理上行共享信道PUSCH持续时间不与其他上行调度的PUSCH持续时间重叠的上行调度、或者PUSCH持续时间与仅其他优先级较低的上行调度的PUSCH持续时间重叠的上行调度、或者PUSCH持续时间不与其他优先级较高的配置上行调度的PUSCH持续时间重叠的动态上行调度，若获取到相应的MAC PDU即媒体访问控制协议数据单元，则指示识别的所述HARQ进程触发该MAC PDU的新传。

优选地，如果接收到的上行调度是配置上行调度且其优先级高于同一HARQ进程上的配置上行调度或同一HARQ进程的HARQ缓存区中尚未发送或等待初传的MAC PDU的优先级，则获取与接收到的该配置上行调度相对应的MAC PDU，并指示识别的所述HARQ进程触发所获取的所述MAC PDU的新传。
优选地，对于PUSCH持续时间与其他优先级较高的上行调度的PUSCH持续时间重叠的上行调度，如果所述上行调度用于新传且获取到了相应的MAC PDU，则将所获取的该MAC PDU递交给识别的所述HARQ进程，并 指示识别的所述HARQ进程不触发该MAC PDU的新传；对于PUSCH持续时间与其他优先级较高的上行调度的PUSCH持续时间重叠的上行调度，如果该上行调度用于新传，如果所述上行调度用于新传但没有获取到相应的MAC PDU，则清空识别的所述HARQ进程的HARQ缓存区或者停止识别的所述HARQ进程的配置调度定时器。
优选地，所述动态上行调度的优先级在对应的下行控制信息DCI中指示，所述配置上行调度的优先级由基站通过无线资源控制RRC信令配置。

下面描述本公开涉及的部分术语，如未特别说明，所述术语与3GPP协议当前最新版本中采用的术语相同，现摘录如下。
RRC：Radio Resource Control，无线资源控制。
MAC：Medium Access Control，媒体访问控制。
PDCCH：Physical Downlink Control Channel，物理下行控制信道。
PUSCH：Physical Uplink Shared Channel，物理上行共享信道。
SDU：Service Data Unit，服务数据单元。
PDU：Protocol Data Unit，协议数据单元。
CG：Configured uplink Grant，配置调度或配置上行调度。
DG：Dynamic Grant，动态调度，是指在PDCCH上动态接收到的上行调度。换言之，PDCCH上接收到的为MAC实体的C-RNTI或TC-RNTI(Temporary C-RNTI)的上行调度或者PDCCH上接收到的为MAC实体的CS-RNTI的上行调度(这个上行调度用于配置上行调度上传输的MAC PDU的重传，其中接收到的NDI值为1认为NDI不翻转)。所述PDCCH上接收到的为MAC实体的C-RNTI或TC-RNTI(Temporary C-RNTI)或CS-RNTI的上行调度是由MAC实体的C-RNTI或TC-RNTI或CS-RNTI加扰的PDCCH指示的上行调度，这两种表述可互换使用。
HARQ信息：HARQ information，DL-SCH或UL-SCH传输的HARQ信息由新数据指示(New Data Indicator，NDI)、传输块大小(Transport Block size，TBS)、冗余版本(Redundancy Version，RV)以及HARQ进程号(HARQ process ID)组成。
CS-RNTI：Configured Scheduling RNTI，配置调度RNTI。
ra-ResponseWindow：随机接入响应窗，UE在随机接入响应窗内接收随机接入响应。
本公开中，在一个服务小区上，某个HARQ进程上的动态调度DG的PUSCH持续时间(duration)与另一个HARQ进程上的配置调度CG的PUSCH持续时间重叠(overlap)称为不同HARQ进程DG/CG PUSCH冲突或不同HARQ进程DG/CG冲突。在一个服务小区上，某个HARQ进程上的配置调度CG的PUSCH持续时间与另一个HARQ进程上的配置调度CG的PUSCH持续时间重叠称为不同HARQ进程CG/CG PUSCH冲突或不同HARQ进程CG/CG冲突。某个HARQ进程上的动态调度DG的PUSCH持续时间与该HARQ进程上的配置调度CG的PUSCH持续时间重叠称为相同HARQ进程DG/CG冲突。某个HARQ进程上的上行调度与该HARQ进程的HARQ缓存区存储的尚未发送(或已发送但尚未确认发送成功)的MAC PDU间所发生的冲突(这种冲突主要是使用HARQ缓存区的冲突，因为每个HARQ进程关联一个HARQ缓存区，如果为该上行调度生成MAC PDU，那么存储在HARQ缓存区中的已有MAC PDU将被覆盖/破坏)称为相同HARQ进程上行调度/MAC PDU冲突。不同HARQ进程DG/CG PUSCH冲突包括一个DG与多个不同HARQ进程上的CG间PUSCH持续时间冲突的情况。同样的，不同HARQ进程CG/CG PUSCH冲突也包含多个CG间PUSCH持续时间冲突的情况。如未特别说明，本公开实施例所述DG/CG或CG/CG冲突包括以上各类冲突，且所述冲突是指发生冲突的DG和CG以及发生冲突的两个或多个CG均在同一个服务小区上。在本公开中，不同的上行调度发生PUSCH重叠是指不同的上行调度在时域上重叠。
当对应HARQ进程的配置调度定时器到期或在一个MAC PDU发送完成后接收到NDI翻转的动态调度时，UE或MAC实体认为这个MAC PDU发送成功。
用户设备UE接收到上行调度(DG或CG)(可由UE中的上行调度接收执行)，且该上行调度与其他上行调度(CG或DG)发生不同HARQ进程DG/CG PUSCH冲突(基站为UE配置了CG)，则判断DG与CG的优先级并根据判断结果执行相应的操作(可由UE中的上行调度接收执行或HARQ 实体执行)。具体描述如下：
在一个实施例中，DG和/或CG用于新传(例如，对于DG，当NDI翻转时用于新传，对于CG，当对应的配置调度定时器configuredGrantTimer未运行时用于新传)，当发生不同HARQ进程DG/CG PUSCH冲突时，如果DG的优先级较高，则UE不为CG生成MAC PDU，忽略CG。当DG的优先级较低时，如果DG用于新传(即HARQ实体需要获取MAC PDU)，为DG生成/获取MAC PDU(可由HARQ实体执行)并存储在对应HARQ进程的缓存区中(可由对应的HARQ进程执行)；如果DG用于重传，重启配置调度定时器configuredGrantTimer(可由HARQ实体执行)。
下面具体描述在发生DG/CG或CG/CG冲突时用户设备UE的上行调度接收(UL Grant reception)执行的操作的实施例。
对于发生不同HARQ进程DG/CG PUSCH冲突的场景，UE的上行调度接收在PDCCH上接收到为MAC实体的C-RNTI的上行调度，如果配置了第一使能优先级指示标识且/或所述标识的取值为1或真或TRUE或setup或第一预定义的值或所述标识出现(或者所述标识的取值为0或假或False或Release或所述标识不出现)，如果该上行调度的PUSCH持续时间不与其他上行调度的PUSCH的持续时间重叠或者仅与优先级低于或不高于该上行调度的其他上行调度(例如CG)的PUSCH的持续时间重叠，则将该上行调度和/或相关的HARQ信息指示给HARQ实体；可选的，如果前一个递交给HARQ实体的同一HARQ进程(就是接收到的上行调度对应的HARQ进程)的上行调度是配置上行调度或者是为MAC实体的CS-RNTI的上行调度时，则认为对应HARQ进程的NDI翻转而不管NDI的值(consider the NDI to have been toggled for the corresponding HARQ process regardless of the value of the NDI)。否则(即如果没有配置第一使能优先级指示标识或所述标识的取值为0或假或False或release或所述标识不出现(或者所述标识的取值为1或真或TRUE或setup或所述标识出现))，将该上行调度和/或相关的HARQ信息指示给HARQ实体；可选的，如果前一个递交给该HARQ实体的同一HARQ进程(就是接收到的上行调度对应的HARQ进程)的上行调度是配置上行调度或者是为MAC实体的CS-RNTI的上行调度时，则认为对应HARQ进程的NDI翻转而不管NDI的值。需要 说明的是，判断条件“前一个递交给该HARQ实体的同一HARQ进程的上行调度是否是配置上行调度或者是为MAC实体的CS-RNTI的上行调度”可以独立于判断条件是否配置了第一使能优先级指示标志，即，对于接收到的上行调度，只要满足前一个递交给HARQ实体的同一HARQ进程的上行调度是配置上行调度或者是为MAC实体的CS-RNTI的上行调度，则认为对应HARQ进程的NDI翻转。
在发生不同HARQ进程DG/CG或CG/CG PUSCH冲突的场景中，对于每个服务小区的每个配置调度(被配置且被激活)，如果没有配置第一使能优先级指示标识或者所述标识的取值为0或假或False或Release或第二预定义的值或所述标识不出现(或者所述标识的取值为1或真或TRUE或setup或所述标识出现)(这个条件是可选的)，且如果该配置调度的PUSCH持续时间不与其他上行调度的PUSCH持续时间重叠，如果还满足该配置调度对应的HARQ进程的配置调度定时器未运行(这个条件是可选的)(在这三个条件都需要执行或需要其中任意两个的情况下，它们的执行顺序包括但不限于上述列出的顺序，可以任意交换它们的顺序形成新的实施例)，则将该配置调度和/或相关的HARQ信息指示给HARQ实体；可选的，还认为对应HARQ进程的NDI翻转。如果配置了第一使能优先级指示标识且/或所述标识的取值为1或真或TRUE或setup或第一预定义的值或所述标识出现(或者所述标识的取值为0或假或False或Release或所述标识不出现)(这个条件是可选的)，且如果该配置调度的PUSCH持续时间仅与优先级低于(或不高于)该配置调度的其他上行调度的PUSCH持续时间重叠或者该配置调度的PUSCH持续时间不与其他上行调度的PUSCH的持续时间重叠，如果还满足对应的HARQ进程的配置调度定时器未运行(这个条件是可选的)(在这三个条件都需要执行或需要其中任意两个的情况下，它们的执行顺序包括但不限于上述列出的顺序，可以任意交换它们的顺序形成新的实施例)，则将该配置调度和/或相关的HARQ信息指示给HARQ实体，可选的，还认为对应HARQ进程的NDI翻转。
可选的，如果对应的HARQ进程的配置调度定时器正在运行，则还需要判断该配置调度的优先级是否比该HARQ进程缓存区中保存的(或保存且尚未发送的)MAC PDU的优先级更高，如果该配置调度的优先级比该HARQ进程缓存区中保存的(或保存且尚未发送的)MAC PDU的优先级更 高，则将该配置调度和/或相关的HARQ信息指示给HARQ实体，可选的，还认为对应HARQ进程的NDI翻转。(应用于支持相同HARQ进程CG/MAC PDU冲突的情况)
可选的，如果对应的HARQ进程的配置调度定时器正在运行，则还需要判断是否配置了第二使能优先级指示标识和判断该配置调度的优先级是否比该HARQ进程缓存区中保存的(或保存且尚未发送的)MAC PDU的优先级更高，如果配置了第二使能优先级指示标识且/或所述标识的取值为1或真或TRUE或setup或第一预定义的值或所述标识出现(或者所述标识的取值为0或假或False或release或所述标识不出现)且该配置调度的优先级比该HARQ进程缓存区中保存的(或保存且尚未发送的)MAC PDU的优先级更高，则将该配置调度和/或相关的HARQ信息指示给HARQ实体，可选的，还认为对应HARQ进程的NDI翻转。(应用于支持相同HARQ进程CG/MAC PDU冲突的情况)
需要说明的是，本公开所述其他上行调度包括在PDCCH上接收到的上行调度和/或其他配置调度和/或随机接入响应中的上行调度。在本公开实施例中，某上行调度的PUSCH持续时间仅与优先级低于或不高于该上行调度的其他上行调度的PUSCH的持续时间重叠是指该上行调度的PUSCH持续时间不与优先级不低于或高于该上行调度的其他上行调度的PUSCH的持续时间重叠。
在发生相同HARQ进程DG/MAC PDU冲突的场景中，UE的上行调度接收在PDCCH上接收到为MAC实体的C-RNTI的上行调度，如果配置了第二使能优先级指示标识且所述标识的取值为1或真或TRUE或setup或第一预定义的值或所述标识出现(或者所述标识的取值为0或假或False或release或所述标识不出现)，如果该上行调度对应的HARQ进程的配置调度定时器未运行，则将该上行调度和/或相关的HARQ信息指示给HARQ实体；可选的，如果前一个递交给HARQ实体的同一HARQ进程(就是接收到的上行调度对应的HARQ进程)的上行调度是配置上行调度或者是为MAC实体的CS-RNTI的上行调度时，则认为对应HARQ进程的NDI翻转而不管NDI的值。如果该上行调度对应的HARQ进程的配置调度定时器正在运行且如果前一个递交给HARQ实体的同一HARQ进程(就是接收到的上行调度对应的HARQ进程)的上行调度是配置上行调度或者是为MAC 实体的CS-RNTI的上行调度且如果该接收到的上行调度的优先级比该HARQ进程缓存区中保存的(或保存且尚未发送的)MAC PDU的优先级更高，则将该接收到的上行调度和/或相关的HARQ信息指示给HARQ实体，可选的，认为对应HARQ进程的NDI翻转。
需要说明的是，本公开中，第一使能优先级指示标识应用于不同HARQ进程上DG/CG或CG/CG PUSCH冲突，第二使能优先级指示标识应用于相同HARQ进程DG/CG或上行调度/MAC PDU冲突。配置了使能优先级指示标识(包括第一使能优先级指示标识和第二使能优先级指示标识)且/或所述标识的取值为1或真或TRUE或setup或第一预定义的值或所述标识出现(或者所述标识的取值为0或假或False或release或第二预定义的值或所述标识不出现)表示在发生不同HARQ进程DG/CG或CG/CG PUSCH冲突或者相同HARQ进程DG/CG或上行调度/MAC PDU冲突时，系统或UE支持比较发生冲突的上行调度和/或MAC PDU的优先级，并根据比较结果执行实施例中定义的操作。没有配置第一使能优先级指示标识或所述标识的取值为0或假或False或release或第二预定义的值或所述标识不出现(或者所述标识的取值为1或真或TRUE或setup或第一预定义的值或所述标识出现)是指系统或UE不支持使能优先级指示标识或者当发生不同HARQ进程DG/CG PUSCH冲突时，总是认为DG的优先级更高，即认为对应HARQ进程的NDI翻转并将DG及其HARQ信息递交给HARQ实体。此外，使能优先级指示标识的取值不限于所列举的取值，也可以是其他预先规定的取值，例如使能和/或去使能。如果系统或UE不支持使能优先级指示标识，则只判断其他条件是否满足而忽略关于是否配置了使能优先级指示标识的判断。第一使能优先级指示标识和第二使能优先级指示标识可以合并为一个指示标识(记为，使能优先级指示标识)，相应的，本公开实施例中第一使能优先级指示标识和第二使能优先级指示标识都替换为使能优先级指示标识。
在3GPP TS38.321最新发布的版本15(TS38.321-f50)中，当发生DG/CG冲突时总是认为DG的优先级高于CG，DG总是覆盖CG，利用DG传输数据而忽略CG。换言之，在接收到DG时，总是将DG递交给HARQ实体，HARQ实体为DG构建MAC PDU(对于新传)或指示HARQ进程进行重 传；在接收到CG时，如果CG的PUSCH持续时间不与其他上行调度的PUSCH持续时间重叠且对应HARQ进程的配置调度定时器未运行，才将该CG递交给HARQ实体。在本公开中，通过引入使能优先级指示标识(包括第一和/或第二使能优先级指示标识)来指示UE处理不同HARQ进程DG/CG PUSCH持续时间冲突和/或不同HARQ进程CG/CG PUSCH持续时间冲突和/或相同HARQ进程DG/CG冲突和/或相同HARQ进程上行调度/MAC PDU冲突(指示在发生冲突时UE进行优先级比较)，使得优先级较高的CG可以覆盖优先级较低的DG(或其他CG)或采用优先级较高的上行调度传输数据或将优先级较高的上行调度递交给HARQ实体或为优先级较高的上行调度生成/获取MAC PDU或忽略优先级较低的DG。所述使能优先级指示标识(包括第一和/或第二使能优先级指示标识)是基站预先通过RRC信令/消息为用户设备UE配置的(例如，在为UE配置配置调度时配置使能优先级指示标识，使能优先级指示标识可以包含在用于配置上行带宽片段BWP的UE特定参数的信元BWP-UplinkDedicated中或者包含在系统信息中)。所述标识可用于指示当发生DG/CG冲突时，是否采用优先级较高的CG而忽略优先级较低的DG或者当接收到优先级较低的DG时是否递交给HARQ实体或是否生成/获取MAC PDU或是否执行重传或者是否处理优先级较低的DG或者是否将CG递交给HARQ实体；或者用于指示当发生CG/CG冲突时，是否采用优先级较高的CG而忽略优先级较低的CG或者当接收到优先级较低的CG时是否递交给HARQ实体或是否生成/获取MAC PDU。在DG和CG冲突发生在同一HARQ进程时，将较高优先级的上行调度递交给HARQ实体，HARQ实体为其产生MAC PDU，这将导致优先级较低的CG被忽略或者对应HARQ进程中保存的为较低优先级上行调度生成的MAC PDU(这个MAC PDU可以是尚未发送，或者已发送但尚未被确认正确接收(例如对应的配置调度定时器正在运行))将被清空(flush)或被为较高优先级上行调度生成的MAC PDU覆盖。所述第一和/或第二使能优先级指示标识可以包含在ConfiguredGrantConfig信元中，所述ConfiguredGrantConfig信元用于配置没有动态调度时根据两种可能机制的上行传输(the IE ConfiguredGrantConfig is used to configure uplink transmission without dynamic grant according to two possible schemes)；实际的上行调度可以是通过RRC配置(type 1)或由PDCCH提供(地址为 CS-RNTI)(type 2)。当所述第一和/或第二使能优先级指示标识的取值为1或真或TRUE或setup或所述标识出现时，采用优先级较高的上行调度传输数据或将优先级较高的上行调度递交给HARQ实体或为优先级较高的上行调度构建MAC PDU；当所述使能优先级指示标识的取值为0或假或False或release或所述标识不出现时，总是认为DG的优先级最高或DG的优先级比CG高或上行调度的优先级比对应HARQ进程缓存区中保存的(或保存且尚未发送的)MAC PDU的优先级高。反之亦然。
下面通过具体的实施例描述冲突的处理过程。
实施例一
图2是示出了根据本发明的实施例一的由用户设备执行的方法的流程图。
如图2所示，在本发明的实施例一中，用户设备UE执行的步骤包括：步骤S201、步骤S203和步骤S205。
在步骤S201，用户设备UE的上行调度接收在PDCCH上接收到为MAC实体的C-RNTI的上行调度(动态上行调度)。
在步骤S203，针对接收到的动态上行调度，判断是否满足以下所述的第一设定条件。
在步骤S205，当前一个递交给HARQ实体的同一HARQ进程(就是接收到的上行调度对应的HARQ进程)的上行调度是配置上行调度或者是为MAC实体的CS-RNTI的上行调度时，如果满足第一设定条件，则认为对应HARQ进程的NDI翻转而不管NDI的值，可选地，还将该上行动态调度递交给HARQ实体。所述第一设定条件可以是以下任意一项或其任意组合：
1)用户设备被配置了第一使能优先级指示标识且/或所述标识的取值为1或真或TRUE或setup或第一预定义的值或所述标识出现(或者所述标识的取值为0或假或False或release或所述标识不出现)；并且如果接收到的上行调度的PUSCH持续时间不与其他上行调度的PUSCH持续时间重叠或不与其他优先级较高的上行调度的PUSCH持续时间重叠或者仅与优先级低于或不高于该上行调度的其他上行调度的PUSCH持续时间重叠；并且接收到的上行调度的优先级比该HARQ进程缓存区中保存的(或保存且尚未 发送的)MAC PDU的优先级更高(这个条件是可选的)；并且该HARQ进程的配置调度定时器正在运行(这个条件是可选的)。
2)用户设备被配置了第一使能优先级指示标识且/或所述标识的取值为1或真或TRUE或setup或第一预定义的值或所述标识出现(或者所述标识的取值为0或假或False或release或所述标识不出现)；并且如果接收到的上行调度的PUSCH持续时间不与其他上行调度的PUSCH持续时间重叠或不与其他优先级较高的上行调度的PUSCH持续时间重叠或者仅与优先级低于或不高于该上行调度的其他上行调度的PUSCH持续时间重叠；并且该HARQ进程的配置调度定时器未运行(这个条件是可选)。
3)如果接收到的上行调度的PUSCH持续时间不与其他上行调度的PUSCH持续时间重叠或不与其他优先级较高的上行调度的PUSCH持续时间重叠或者仅与优先级低于或不高于该上行调度的其他上行调度的PUSCH持续时间重叠；并且接收到的上行调度的优先级比该HARQ进程缓存区中保存的(或保存且尚未发送的)MAC PDU的优先级更高(这个条件是可选的)；并且该HARQ进程的配置调度定时器正在运行(这个条件是可选)。
4)如果接收到的上行调度的PUSCH持续时间不与其他上行调度的PUSCH持续时间重叠或不与其他优先级较高的上行调度的PUSCH持续时间重叠或者仅与优先级低于或不高于该上行调度的其他上行调度的PUSCH持续时间重叠；并且该HARQ进程的配置调度定时器未运行(这个条件是可选)。
5)用户设备被配置了第二使能优先级指示标识且/或所述标识的取值为1或真或TRUE或setup或第一预定义的值或所述标识出现(或者所述标识的取值为0或假或False或release或所述标识不出现)，并且该HARQ进程对应的配置调度定时器正在运行(这个条件是可选)，并且接收到的上行调度的优先级比该HARQ进程缓存区中保存的(或保存且尚未发送的)MAC PDU的优先级更高。
5)接收到的上行调度的优先级比对应的HARQ进程的缓存区中保存的(或保存且尚未发送)MAC PDU的优先级更高；并且该HARQ进程的配置调度定时器正在运行(这个条件是可选)。
6)接收到的上行调度比前一个上行调度优先级更高(或接收到的上行调度比前一个生成了MAC PDU但未发送的上行调度的优先级更高，或接 收到的上行调度比前一个生成了MAC PDU但被忽略的上行调到的优先级更高)；并且该HARQ进程对应的配置调度定时器正在运行(这个条件是可选)。
7)该接收到的上行调度对应的HARQ进程对应的配置调度定时器未运行；
8)如果没有配置第一使能优先级指示标识或所述标识的取值为0或假或False或release或第二预定义的值或所述标识不出现(或者所述标识的取值为1或真或TRUE或setup或所述标识出现)，可选地，并且如果接收到的上行调度的PUSCH持续时间不与其他上行调度的PUSCH持续时间重叠或不与其他优先级较高的上行调度的PUSCH持续时间重叠或者仅与优先级低于或不高于该上行调度的其他上行调度的PUSCH持续时间重叠。
在上述第一设定条件(1-8)中，所有的条件可以分为两类，一类用于处理不同HARQ进程上DG/CG PUSCH持续时间冲突，这类条件包括以下中的任一个或其任意组合：是否配置了第一使能优先级指示标识、接收到的上行调度的PUSCH持续时间是否与其他上行调度的PUSCH持续时间重叠。另一类条件用于处理相同HARQ进程DG/CG或上行调度/MAC PDU冲突，这类条件包括以下中的任一个或其任意组合：是否配置了第二使能优先级指示标识、对应的配置调度定时器是否正在运行、接收到的上行调度的优先级是否比该HARQ进程缓存区中保存的(或保存且尚未发送的)MAC PDU的优先级更高、接收到的上行调度是否比前一个上行调度优先级更高。这两类条件分别只有在系统或UE支持处理对应类型的冲突时才需要，比如，如果系统或UE不支持处理相同HARQ进程DG/CG或上行调度/MAC PDU冲突(换言之，总认为接收到的上行调度总是优先级更高，为该上行调度生成的MAC PDU将覆盖当前HARQ缓存区保存的MAC PDU)，则第一设定条件中不包括用于处理相同HARQ进程DG/CG或上行调度/MAC PDU冲突的条件。此外，本公开所述接收到的上行调度的优先级比该HARQ进程缓存区中保存的(或保存且尚未发送的)MAC PDU的优先级更高可以替换为所述接收到的上行调度的优先级不低于该HARQ进程缓存区中保存的(或保存且尚未发送的)MAC PDU的优先级。此外，上述条件(1-8)中的每一项都含有多个判定条件(条件(7)除外)，在每一项中这些判定条件的执行顺序包括但不限于上述列出的顺序，也可以交换这些 判断条件的顺序形成新的实施例。
更进一步的，用户设备UE的上行调度接收在PDCCH上接收到为MAC实体的C-RNTI的上行调度，并且满足第一设定条件，则还可以执行以下操作至少一项：
1)将所述接收到的上行调度和相关的HARQ信息递交给HARQ实体(deliver the uplink grant and the associated HARQ information to the HARQ entity)。
2)如果对应的HARQ进程配置了配置调度定时器，启动或重启对应的HARQ进程的配置调度定时器(start or restart the configuredGrantTimer for the correponding HARQ process，if configured)。
可选的，用户设备UE的上行调度接收在PDCCH上接收到为MAC实体的C-RNTI的上行调度并且不满足第一设定条件，则执行以下操作至少一项：
1)如果前一个递交给HARQ实体的同一HARQ进程的上行调度是为MAC实体的C-RNTI的上行调度，将所述接收到的上行调度和相关的HARQ信息递交给HARQ实体(deliver the uplink grant and the associated HARQ information to the HARQ entity)；
2)如果对应的HARQ进程是为配置调度配置的HARQ进行并且配置了配置调度定时器，则启动或重启对应HARQ进程的配置调度定时器；
3)忽略接收到的上行调度。
在另一个实施例中，用户设备UE的上行调度接收在PDCCH上接收到为MAC实体的C-RNTI的上行调度，如果前一个递交给HARQ实体的同一HARQ进程(就是接收到的上行调度对应的HARQ进程)的上行调度是配置上行调度或者是为MAC实体的CS-RNTI的上行调度，则认为对应HARQ进程的NDI翻转而不管NDI的值(consider the NDI to have been toggled for the corresponding HARQ process regardless of the value of the NDI)。如果满足前述第一设定条件，则可以执行前述满足第一设定条件时可以执行的其他操作。
在本公开实施例中，HARQ进程的缓存区中保存且尚未发送的MAC  PDU是指HARQ进程缓存区不为空且其中存储的MAC PDU尚未发送或HARQ进程的缓存区中包含尚未发送的MAC PDU。当对应不同HARQ进程的DG与CG之间或CG与CG间发生了冲突，HARQ实体为优先级较低的上行调度生成了MAC PDU并存储在缓存区中，但由于对应的上行调度优先级较低被忽略而没有利用该上行调度发送所述MAC PDU，所述MAC PDU就是指尚未发送的MAC PDU，也可称为等待初传的MAC PDU。
实施例二
图3是示出了根据本发明的实施例二的由用户设备执行的方法的流程图。
如图3所示，在本发明的实施例二中，用户设备UE执行的步骤包括：步骤S301、步骤S303和步骤S305。
在实施例二中，在步骤S301，对于每个服务小区，接收针对MAC实体的配置上行调度(MAC实体可以执行以下操作)，
在步骤S303，针对接收到的配置上行调度，判断是否满足第二设定条件。
在步骤S305，如果满足第二设定条件，则执行以下操作中的一项或多项(例如，将该配置上行调度递交给HARQ实体)：
1)设置HARQ进程号(HARQ process ID)为这个配置上行调度PUSCH持续时间对应的HARQ进程号；
2)如果对应HARQ进程的配置调度定时器未运行；或者，对应HARQ进程的缓存区为空或对应HARQ进程的配置调度定时器正在运行但HARQ进程的缓存区为空(这个条件是可选的)，则认为对应HARQ进程的NDI翻转，和/或将配置上行调度及其相关的HARQ信息递交给HARQ实体(可选的)。可选的，如果对应HARQ进程的配置调度定时器正在运行，且HARQ缓存区存在尚未发送的MAC PDU(例如，该MAC PDU是为前一个优先级较低的配置上行调度生成的)，则认为对应HARQ进程的NDI没有翻转。
3)将配置上行调度及其相关的HARQ信息递交给HARQ实体(如果2)中执行了此操作，则此处不再执行)。
4)启动对应HARQ进程的配置调度定时器(如果配置了配置调度定时器才执行此操作)。
可选的，如果不满足第二设定条件，忽略该配置上行调度或不将该配置上行调度递交给HARQ实体。
具体的，所述第二设定条件可为以任意一项或其任意组合：
1)UE被配置了第一使能优先级指示标识且所述标识的取值为1或真或TRUE或setup或第一预定义的值或所述标识出现(或者所述标识的取值为0或假或False或release或所述标识不出现)；并且对应HARQ进程的配置调度定时器未运行(可选的)。
2)UE被配置了第一使能优先级指示标识且所述标识的取值为1或真或TRUE或setup或第一预定义的值或所述标识出现(或者所述标识的取值为0或假或False或release或所述标识不出现)；并且(或者)配置上行调度的PUSCH持续时间与同一服务小区的其他上行调度的PUSCH持续时间重叠但该配置上行调度优先级较高或者该配置上行调度不与同一服务小区的其他上行调度的PUSCH持续时间重叠或者配置上行调度的PUSCH持续时间仅与优先级低于(或不高于)该配置上行调度的其他上行调度的PUSCH持续时间重叠；并且对应的HARQ进程的配置调度定时正在运行但该配置调度优先级更高(与缓存区中的MAC PDU的优先级进行比较)(可选)或该配置上行调度对应的HARQ进程的配置调度定时器未运行。
3)UE没有被配置第一使能优先级指示标识或所述标识的取值为0或假或False或release或第二预定义的值或所述标识不出现(或者所述标识的取值为1或真或TRUE或setup或所述标识出现)，并且/或者配置上行调度的PUSCH持续时间与PDCCH上接收到的同一服务小区的上行调度的PUSCH持续时间或同一服务小区上的其他配置上行调度的PUSCH持续时间或随机接入响应中的上行调度的PUSCH持续时间不重叠；并且对应HARQ进程的配置调度定时器未运行。可选的，对应HARQ进程的配置调度定时器正在运行，如果被配置了第二使能优先级指示标识或所述标识的取值为0或假或False或release或第二预定义的值或所述标识不出现(或者所述标识的取值为1或真或TRUE或setup或所述标识出现)且该配置调度优先级更高(与缓存区中的MAC PDU的优先级进行比较)。
4)配置上行调度的PUSCH持续时间与PDCCH上接收到的同一服务小区的上行调度的PUSCH持续时间重叠或与同一服务小区上的其他配置上行调度的PUSCH持续时间重叠，但该配置上行调度的优先级更高；或者 配置上行调度的PUSCH持续时间不与随机接入响应中的上行调度的PUSCH持续时间重叠但与PDCCH上接收到的同一服务小区的上行调度或同一服务小区的其他配置上行调度的PUSCH持续时间重叠但该配置上行调度的优先级更高。
5)UE被配置了第二使能优先级指示标识且所述标识的取值为1或真或TRUE或setup或第一预定义的值或所述标识出现(或者所述标识的取值为0或假或False或release或所述标识不出现)；并且对应的HARQ进程的配置调度定时正在运行(可选)但该配置调度优先级更高(与缓存区中的MAC PDU的优先级进行比较)或该配置上行调度对应的HARQ进程的配置调度定时器未运行。
可选的，在上述第二设定条件(1-5)中，如果接收到或可用的配置上行调度的PUSCH持续时间与随机接入响应中的上行调度的PUSCH持续时间重叠，则忽略该配置上行调度或不将该配置上行调度递交给HARQ实体(即总认为随机接入响应中的上行调度优先级最高，这也可应用于本公开其他实施例)。
在上述第二设定条件(1-5)中，所有的条件可以分为两类，一类用于处理不同HARQ进程上DG/CG或CG/CG PUSCH持续时间冲突，这类条件包括以下中的任一个或其任意组合：是否配置了第一使能优先级指示标识、接收到的配置上行调度的PUSCH持续时间是否与其他上行调度(例如另一配置上行调度或DG或随机接入响应的上行调度)的PUSCH持续时间重叠。另一类条件用于处理相同HARQ进程配置上行调度/MAC PDU冲突，这类条件包括以下中的任一个或其任意组合：是否配置了第二使能优先级指示标识、对应的配置调度定时器正在运行但该配置调度优先级更高(与缓存区中的MAC PDU的优先级进行比较)。这两类条件只有在系统或UE支持处理对应类型的冲突时才需要，比如，如果系统或UE不支持处理相同HARQ进程配置上行调度/MAC PDU冲突(换言之，如果对应的配置调度定时器正在运行，则不将该配置上行调度递交给HARQ实体)，则第一设定条件中不包括用于处理相同HARQ进程配置上行调度/MAC PDU冲突的条件。此外，如果系统或UE不支持使能优先级指示标识(包括第一使能优先级指示标识和第二使能优先级指示标识)，则上述第二设定条件(1-5)中关 于是否配置了使能优先级指示标识的判断都可以删除。此外，上述条件(1-5)中的对于包含多个判定条件的项，这些判定条件的执行顺序包括但不限于上述列出的顺序，可以交换这些判断条件的顺序形成新的实施例。
本公开实施例中所述为MAC实体的C-RNTI或CS-RNTI或TC-RNTI的上行调度或者在PDCCH上接收到为MAC实体的C-RNTI或CS-RNTI或TC-RNTI的上行调度是指由C-RNTI或CS-RNTI或TC-RNTI加扰的PDCCH指示的上行调度。
本公开实施例中，动态调度的优先级可以在其对应的下行控制信息DCI中指示，配置调度的优先级可由基站通过RRC信令/消息配置或者在用于激活该配置调度的下行控制信息DCI中指示，也可以是这个上行调度可发送或可复用或将要复用或已复用(由复用和组装过程根据逻辑信道优先级LCP过程执行)的数据对应的逻辑信道的最高优先级(即所包含的数据对应的优先级最高的那个逻辑信道的优先级)或将要为这个上行调度生成的MAC PDU中包含的数据对应的优先级最高的逻辑信道的优先级。MAC PDU的优先级是指MAC PDU包含的数据对应的优先级最高的逻辑信道的优先级或该MAC PDU对应的上行调度的优先级(该MAC PDU是为该上行调度生成的MAC PDU)。某个上行调度与MAC PDU比较优先级是表示该上行调度的优先级与MAC PDU对应的上行调度的优先级进行比较或者是为该上行调度生成的MAC PDU的优先级与该MAC PDU的优先级进行比较。如果上行调度的优先级由其对应的MAC PDU决定或由对应优先级最高的逻辑信道的优先级决定，那么上行调度之间的优先级比较就是它们对应的MAC PDU的优先级或它们对应的优先级最高的逻辑信道的优先级的比较。相应的，上行调度接收或HARQ实体在处理相应的上行调度时，在与其他上行调度进行优先级比较前先向“决定上行调度优先级过程”获取该上行调度的优先级，例如向复用与组装过程获取优先级，然后将获取的优先级与其他上行调度的优先级进行比较。“决定上行调度优先级过程”(例如复用与组装过程)在接收到获取上行调度优先级的指示时，根据逻辑信道优先级LCP的限定条件(或RRC为每个逻辑信道配置的映射限制)确定该上行调度可发送或可复用或将要复用的数据对应的优先级最高的逻辑信道的优先级，或者将为该上行调度选择或预选的逻辑信道中优先级最高的逻辑信道的优先级作为该上行调度的优先级(“决定上行调度优先级过 程”所选择的逻辑信道中有可发送数据，如果根据LCP规则所有逻辑信道都没有数据可发送，则可为对应上行调度的优先级为一个预定义的值，例如为0。也可以为只有MAC CE可发送和没有数据和MAC CE可发送分别预定义不同的值)，并指示给上行调度接收或HARQ实体。此外，如果上行调度接收获取了/接收到了某个上行调度的优先级，在上行调度接收将该上行调度递交给HARQ实体时，可以将该上行调度的优先级也递交给HARQ实体。对于HARQ实体来说，如果从上行调度接收收到了某个上行调度的优先级，那么不需要向“决定上行调度优先级过程”获取该上行调度的优先级，但如果没有收到某个上行调度的优先级，那么可以向“决定上行调度优先级过程”获取该上行调度的优先级。可选的，HARQ实体在将上行调度递交给HARQ进程时，将该上行调度的优先级也指示给HARQ进程。
下面具体描述在发生DG/CG或CG/CG冲突时用户设备UE的HARQ实体执行的操作实施例。
以下描述HARQ实体对接收到的上行调度的一种处理方式。
对于PUSCH持续时间不与其他上行调度的PUSCH持续时间重叠的上行调度，或者对于PUSCH持续时间仅与优先级较低的其他上行调度的PUSCH持续时间重叠的上行调度，或者该上行调度的PUSCH持续时间与其他优先级较低的上行调度的PUSCH持续时间重叠，或者PUSCH持续时间不与其他优先级较高的配置上行调度的PUSCH持续时间重叠的动态调度，识别该上行调度的HARQ进程，并且对于识别的HARQ进程，执行以下操作：
如果该上行调度用于新传(即满足新传条件，例如下面实施例步骤002/003中给出的获取MAC PDU的条件)，则获取MAC PDU。
如果获取到了MAC PDU，则将该MAC PDU、该上行调度以及识别的HARQ进程的传输块的HARQ信息递交给识别的HARQ进程，指示识别的HARQ进程触发新传，如果满足启动识别的HARQ进程的配置调度定时器的条件，则启动或重启识别的HARQ进程的配置调度定时器。
如果没有获取到MAC PDU，则清空识别的HARQ进程的HARQ缓存区，可选的，停止识别的HARQ进程的配置调度定时器(如果正在运行)。
可选的，对于PUSCH持续时间与其他优先级较高的上行调度的PUSCH 持续时间重叠的上行调度，如果该上行调度用于新传(即满足新传条件，例如下面实施例中给出的获取MAC PDU的条件)，则获取MAC PDU。如果获取到了MAC PDU，则将该MAC PDU递交给识别的HARQ进程，将该上行调度和/或识别的HARQ进程的传输块的HARQ信息递交给识别的HARQ进程(这个操作是可选的)，指示识别的HARQ进程不触发新传(或不指示识别的HARQ进程触发新传或指示识别的HARQ进程存储MAC PDU)(这个操作也是可选的)，如果满足启动识别的HARQ进程的配置调度定时器的条件，则启动或重启识别的HARQ进程的配置调度定时器。如果没有获取到MAC PDU，则清空识别的HARQ进程的HARQ缓存区，可选的，停止识别的HARQ进程的配置调度定时器(如果正在运行)。
可选的，对于PUSCH持续时间与其他优先级较高的上行调度的PUSCH持续时间重叠的上行调度，如果该上行调度用于新传(即满足新传条件，例如下面实施例中给出的获取MAC PDU的条件)，则清空识别的HARQ进程的HARQ缓存区，可选的，停止识别的HARQ进程的配置调度定时器(如果正在运行)。
可选的，对于用于重传的上行调度(即不满足新传的条件)，如果该上行调度的PUSCH持续时间与其他优先级较高的上行调度的PUSCH持续时间重叠，则忽略该上行调度，可选的，指示识别的HARQ进程不触发重传(或不指示识别的HARQ进程触发重传)，可选的，如果满足启动识别的HARQ进程的配置调度定时器的条件，则启动或重启识别的HARQ进程的配置调度定时器。
以下是HARQ实体对接收到的上行调度的另一种处理方式。
对于每个上行调度，识别这个上行调度的HARQ进程，对于识别的HARQ进程，如果该上行调度用于新传(即满足新传条件，例如下面实施例步骤002/003中给出的获取MAC PDU的条件)，则获取MAC PDU。如果获取到了MAC PDU，则将该MAC PDU递交给识别的HARQ进程，可选的，还将该上行调度和/或识别的HARQ进程的传输块的HARQ信息递交给识别的HARQ进程，可选的，如果该上行调度的PUSCH持续时间与其他优先级较高的上行调度的PUSCH持续时间重叠，则指示识别的HARQ进程不触发新传或不指示识别的HARQ进程触发新传或指示识别的HARQ进程存储MAC PDU，如果满足启动识别的HARQ进程的配置调度定时器 的条件，则启动或重启识别的HARQ进程的配置调度定时器；如果该上行调度的PUSCH持续时间仅与优先级低于(或不高于)该上行调度的其他上行调度的PUSCH持续时间重叠，则指示识别的HARQ进程触发新传，可选的，还将该上行调度和/或识别的HARQ进程的传输块的HARQ信息递交给识别的HARQ进程(如果在判断上行调度的优先级与其他上行调度的优先级之前已经执行该操作，则此处不执行)。如果没有获取到MAC PDU，则清空识别的HARQ进程的HARQ缓存区，可选的，停止识别的HARQ进程的配置调度定时器(如果正在运行)。如果该上行调度用于重传，且满足以下条件之一，则忽略这个上行调度，停止识别的HARQ进程的配置调度定时器(如果正在运行)：(1)如果该上行调度由CS-RNTI加扰的PDCCH指示且识别的HARQ进程的HARQ缓存区为空；(2)如果该上行调度是一组上行调度的一部分且没有为这组上行调度获取到MAC PDU；(3)如果该上行调度是一组上行调度的一部分且该上行调度的PUSCH持续时间与这个服务小区上的另一个由PDCCH持续时间或随机接入响应指示的上行调度的PUSCH持续时间重叠；(4)如果该上行调度的PUSCH持续时间与优先级不低于(或高于)该上行调度的其他上行调度的PUSCH持续时间重叠。
所述启动识别的HARQ进程的配置调度定时器的条件为：如果该上行调度对应CS-RNTI，或者该上行调度是配置上行调度，或者该上行调度对应C-RNTI且识别的HARQ进程被配置了配置上行调度，则如果配置了配置调度定时器，当执行传输时启动或重启配置调度定时器。
需要说明的是，在上行调度接收执行的操作实施例中定义的使能优先级指示标识(包括第一或第二使能优先级指示标识)也可以应用于HARQ实体执行的操作实施例。此时，在HARQ实体执行的操作实施例中，只有在配置了使能优先级指示标识且/或所述标识的取值为1或真或TRUE或setup或第一预定义的值或所述标识出现(或者所述标识的取值为0或假或False或release或所述标识不出现)时才判断接收到的上行调度的PUSCH持续时间与其他上行调度的PUSCH持续时间是否重叠，并根据判断结果执行实施例中所定义的操作。如果没有配置使能优先级指示标识或标识的取值为0或假或False或第二预定义的值或所述标识不出现(或者所述标识的取值为1或真或TRUE或所述标识出现)时，按照实施例中不执行判断接收到的上行调度的PUSCH持续时间与另一个上行调度的PUSCH持续时间 是否重叠操作的方式执行(即默认条件满足)。在HARQ实体执行的操作实施例中，对使能优先级指示标识和上行调度间优先级比较的判断与在上行调度接收执行的操作实施例中定义的第一设定条件(1-8)和第二设定条件(1-5)相同。
下面通过具体的实施例对上述两种处理方式更详细的描述。
实施例三
图4是示出了根据本发明的实施例三的由用户设备执行的方法的流程图。
如图4所示，在本发明的实施例三中，用户设备UE执行的步骤包括：步骤001～009。

在步骤003，如果消息3(Msg3)缓存区中有MAC PDU且上行调度接收自随机接入响应(if there is a MAC PDU in the Msg3 buffer and the uplink grant was received in a Random Access Response)，或者如果消息3(Msg3)缓存区中有MAC PDU且在ra-ResponseWindow接收到的上行调度是由C-RNTI加扰的PDCCH指示且这个PDCCH成功完成了由波束错误恢复引起的随机接入过程(if there is a MAC PDU in the Msg3 buffer and the uplink grant was received on PDCCH for the C-RNTI in ra-ResponseWindow and this PDCCH successfully completed the Random Access procedure initiated for beam failure recovery)，则执行步骤004(满足所述条件中的至少一个条件)，否则(所述条件均不满足)，执行步骤005。
在步骤004，从Msg3缓存区获取MAC PDU。如果上行调度的大小与获取的MAC PDU大小不匹配并且在接收到该上行调度时随机接入过程成功完成(if the uplink grant size does not match with size of the obtained MAC PDU，and if the Random Access procedure was successfully completed upon receiving the uplink grant)，指示复用和组装实体在后续上行链路传输中包括从获得的MAC PDU携带MAC SDU的MAC subPDU(indicate to the Multiplexing and assembly entity to include MAC subPDU(s)carrying MAC SDU from the obtained MAC PDU in the subsequent uplink transmission)，从复用和组装实体获取MAC PDU用于传输。执行步骤006。
在步骤005，从复用和组装实体获取MAC PDU用于传输(如果存在)(obtain the MAC PDU to transmit from the Multiplexing and assembly entity，if any)。执行步骤006。
在步骤006，如果获取到了用于传输的MAC PDU(if a MAC PDU to transmit has been obtained)，则执行以下操作(并在执行完以下操作后结束)：
(1)将该MAC PDU和/或该上行调度和/或这个传输块的HARQ信息递交给识别的HARQ进程(deliver the MAC PDU and/or the uplink grant and/or the HARQ information of the TB to the identified HARQ process)。
(2)优选的，指示识别的HARQ进程触发新传。备选的，如果该上行调度的PUSCH持续时间不与其他上行调度的PUSCH持续时间重叠或者该上行调度的PUSCH持续时间仅与其他优先级较低的上行调度的PUSCH持续时间重叠(If the uplink grant does not overlap with other uplink grant or if the uplink grant overlaps with other uplink grant with lower priority)或者该上行调度是由C-RNTI加扰的PDCCH指示且与其PUSCH持续时间重叠的配置上行调度的优先级不高于该上行调度(这个操作中的以上这些判断条件是可选的，例如在HARQ实体对每个上行调度执行步骤001及其后续步骤时，才判断是否满足这些条件并在满足其中任一条件时执行后续操作)，则指示识别的HARQ进程触发新传(instruct the identified HARQ process to trigger a new transmission)和/或将该上行调度和/或这个传输块的HARQ信息递交给识别的HARQ进程(deliver the uplink grant and/or the HARQ information of the TB to the identified HARQ process)；否则(可选)，将该上行调度和/或这个传输块的HARQ信息递交给识别的HARQ进程和/或指示识别的HARQ进程不触发新传(或不指示识别的HARQ触发新传或指示识别的HARQ进程存储MAC PDU)和/或忽略该上行调度；可选的，如果该上行调度是由C-RNTI加扰的PDCCH指示且该上行调度的PUSCH持续时间与其他优先级较高的上行调度的PUSCH持续时间重叠(这判断条件是可选的，例如在HARQ实体对每个上行调度执行步骤001及其后续步骤时，才判断是否满足这个条件并在满足条件时执行后续操作)，则将该上行调度和/或这个传输块的HARQ信息递交给识别的HARQ进程和/或指示识别的HARQ进程不触发新传(或不指示识别的HARQ触发新传或指示识别的HARQ进程存储MAC PDU)和/或忽略该上行调度。

否则(没有获取到用于传输的MAC PDU)，则执行步骤007。
在步骤007，清空识别的HARQ进程的HARQ缓存区。可选的，如果配置调度定时器正在运行，则停止配置调度定时器。结束。
在步骤008，如果满足第三设定条件，则忽略该上行调度；如果不满足第三设定条件，则执行步骤009。所述第三设定条件可以是以下至少一个：

(2)如果该上行调度是一组上行调度的一部分且没有为这组上行调度获取到MAC PDU(if the uplink grant is part of a bundle and if no MAC PDU has been obtained for this bundle)
(3)如果该上行调度是一组上行调度的一部分且该上行调度的PUSCH与这个服务小区上的另一个由PDCCH或随机接入响应指示的上行调度的PUSCH重叠(if the uplink grant is part of a bundle of the configured uplink grant，and the PUSCH of the uplink grant overlaps with a PUSCH of another uplink grant received on the PDCCH or in a Random Access Response for this Serving Cell)

实施例四
图5是示出了根据本发明的实施例四的由用户设备执行的方法的流程图。
如图5所示，在本发明的实施例四中，用户设备UE执行的步骤包括：步骤101～113。
在本实施例中，对于每个上行调度(或者对于PUSCH持续时间不与其他上行调度的PUSCH持续时间重叠的上行调度，或者对于PUSCH持续时间仅与其他优先级较低的上行调度的PUSCH持续时间重叠的上行调度，或者PUSCH持续时间不与优先级较高的其他上行调度的PUSCH持续时间重叠的动态调度)，HARQ实体执行以下操作：
在步骤101，识别与该上行调度对应的HARQ进程，并对每个识别的HARQ进程执行步骤102。
在步骤102，如果接收到的上行调度不是由对应TC-RNTI的PDCCH 指示，且相应的HARQ信息中提供的NDI与该HARQ进程的传输块的前一次传输的NDI值相比发生了翻转；或者如果接收到的上行调度是由C-RNTI加扰的PDCCH指示且该识别的HARQ进程的HARQ缓存区为空；或者如果上行调度接收自随机接入响应；或者如果在ra-ResponseWindow内接收到的上行调度是由C-RNTI加扰的PDCCH指示且这个PDCCH成功完成了由波束错误恢复引起的随机接入过程；或者如果上行调度是一组配置上行调度的一部分且可能被用于初始传输且还没有为这组配置上行调度获取MAC PDU，则执行步骤103(满足所述条件中的至少一个条件)，否则(所述条件均不满足)，执行步骤108。
在步骤103，如果消息3(Msg3)缓存区中有MAC PDU且上行调度接收自随机接入响应，或者如果消息3(Msg3)缓存区中有MAC PDU且在ra-ResponseWindow接收到的上行调度是由C-RNTI加扰的PDCCH指示且这个PDCCH成功完成了由波束错误恢复引起的随机接入过程，则执行步骤104(满足所述条件中的至少一个条件)，否则(所述条件均不满足)，执行步骤105。
在步骤104，从Msg3缓存区获取MAC PDU。如果上行调度的大小与获取的MAC PDU大小不匹配并且在接收到该上行调度时随机接入过程成功完成，指示复用和组装实体在后续上行链路传输中包括从获得的MAC PDU携带MAC SDU的MAC subPDU，从复用和组装实体获取MAC PDU用于传输。执行步骤106。
在步骤105，从复用和组装实体获取MAC PDU用于传输(如果存在)。执行步骤106。
在步骤106，如果获取到了用于传输的MAC PDU(if a MAC PDU to transmit has been obtained)，则执行以下操作(并在执行完以下操作后结束)：
(1)将该MAC PDU和/或该上行调度和/或这个传输块的HARQ信息递交给识别的HARQ进程。
(2)优选的，指示识别的HARQ进程触发新传。备选的，如果该上行调度的PUSCH持续时间不与其他上行调度的PUSCH持续时间重叠或者该上行调度的PUSCH持续时间仅与其他优先级较低的上行调度的PUSCH持续时间重叠或者该上行调度是由C-RNTI加扰的PDCCH指示且与其PUSCH持续时间重叠的配置上行调度的优先级不高于该上行调度(这个操 作中的以上这些判断条件是可选的，例如在HARQ实体对每个上行调度执行步骤101及其后续步骤时，才判断是否满足这些条件并在满足其中任一条件时执行后续操作)，则指示识别的HARQ进程触发新传和/或将该上行调度和/或这个传输块的HARQ信息递交给识别的HARQ进程；否则(可选)，将该上行调度和/或这个传输块的HARQ信息递交给识别的HARQ进程和/或指示识别的HARQ进程不触发新传(或不指示识别的HARQ触发新传或指示识别的HARQ进程存储MAC PDU)和/或忽略该上行调度；可选的，如果该上行调度是由C-RNTI加扰的PDCCH指示且该上行调度的PUSCH持续时间与其他优先级较高的上行调度的PUSCH持续时间重叠(这判断条件是可选的，例如在HARQ实体对每个上行调度执行步骤101及其后续步骤时，才判断是否满足这个条件并在满足条件时执行后续操作)，则将该上行调度和/或这个传输块的HARQ信息递交给识别的HARQ进程和/或指示识别的HARQ进程不触发新传(或不指示识别的HARQ触发新传或指示识别的HARQ进程存储MAC PDU)和/或忽略该上行调度。
(3)如果接收到的上行调度对应CS-RNTI，或者接收到的上行调度是配置上行调度，或者接收到的上行调度对应C-RNTI且识别的HARQ进程被配置了配置上行调度，则如果配置了配置调度定时器，当执行传输时启动或重启配置调度定时器configuredGrantTimer；
否则(没有获取到用于传输的MAC PDU)，则执行步骤107。
在步骤107，清空识别的HARQ进程的HARQ缓存区。可选的，如果配置调度定时器正在运行，则停止配置调度定时器。结束。
在步骤108，如果接收到的上行调度由C-RNTI加扰的PDCCH指示且递交给这个HARQ实体的同一HARQ进程(为接收到的上行调度识别的HARQ进程)的另一个上行调度是由CS-RNTI加扰的PDCCH指示或是配置上行调度，或者如果接收到的上行调度是配置上行调度且递交给这个HARQ实体的同一HARQ进程的另一个上行调度是由CS-RNTI或C-RNTI加扰的PDCCH指示，或者识别的HARQ进程的HARQ缓存区中存在尚未发送或等待初传的MAC PDU，则执行步骤109，否则，执行步骤112。
在步骤109，如果这个接收到的配置调度的优先级更高(比同一HARQ进程上的CG或尚未发送或等待初传的MAC PDU的优先级更高，或者不比同一HARQ进程上的CG或尚未发送或等待初传的MAC PDU的优先级 低)，则执行步骤110；否则，执行步骤111。
在步骤110，从复用和组装实体获取用于传输MAC PDU；将该MAC PDU及该上行调度及这个传输块的HARQ信息递交给识别的HARQ进程；指示识别的HARQ进程触发新传；当执行传输时启动或重启识别的HARQ进程对应的配置调度定时器(只有为该配置上行调度配置了配置调度定时器才执行)。结束。
在步骤111，如果接收到的上行调度由C-RNTI加扰的PDCCH指示，则忽略该上行调度。如果接收到的上行调度是配置的上行调度且递交给这个HARQ实体的同一HARQ进程(为接收到的上行调度识别的HARQ进程)的前一个上行调度是由CS-RNTI加扰的PDCCH指示或是配置上行调度，则将待上行调度和这个TB的HARQ信息(冗余版本)递交给识别的HARQ进程；指示识别的HARQ进程触发重传，启动这个HARQ进程的配置调度定时器(如果配置了)。如果以上条件都不满足，则忽略该上行调度。结束。
在步骤112(与上一个实施例三中步骤008相同)，如果满足第四设定条件，则忽略该上行调度；如果不满足第三设定条件，则执行步骤113。所述第四设定条件可以是以下至少一个：
(1)如果该上行调度由CS-RNTI加扰的PDCCH指示(the uplink grant received on PDCCH was addressed to CS-RNTI)且识别的HARQ进程的HARQ缓存区为空；
(2)如果该上行调度是一组上行调度的一部分且没有为这组上行调度获取到MAC PDU(if the uplink grant is part of a bundle and if no MAC PDU has been obtained for this bundle)
(3)如果该上行调度是一组上行调度的一部分且该上行调度的PUSCH与这个服务小区上的另一个由PDCCH或随机接入响应指示的上行调度的PUSCH重叠(if the uplink grant is part of a bundle of the configured uplink grant，and the PUSCH of the uplink grant overlaps with a PUSCH of another uplink grant received on the PDCCH or in a Random Access Response for this Serving Cell)
(4)该上行调度由PDCCH指示且/或该上行调度的PUSCH持续时间与另一个优先级较高的上行调度的PUSCH持续时间重叠。
可选的，在步骤112中，如果该上行调度被忽略，如果该上行调度由CS-RNTI加扰的PDCCH指示和/或如果识别的HARQ进程对应的配置调度定时器正在运行，则停止该配置调度定时器。
可选的，在步骤112中，如果该上行调度由CS-RNTI加扰的PDCCH指示(the uplink grant received on PDCCH was addressed to CS-RNTI)且识别的HARQ进程的HARQ缓存区为空，如果识别的HARQ进程对应的配置调度定时器正在运行(只有当该HARQ进程上配置了配置上行调度和/或配置调度定时器时才执行)，则停止该配置调度定时器。
可选的，在步骤112中，如果该上行调度由PDCCH指示且/或该上行调度的PUSCH持续时间与另一个优先级较高的上行调度的PUSCH持续时间重叠，如果识别的HARQ进程对应的配置调度定时器正在运行(只有当该HARQ进程上配置了配置上行调度和/或配置调度定时器时才执行)，则停止该配置调度定时器。
在步骤113(与上一个实施例三中步骤009相同)，将该上行调度和该传输块对应的HARQ信息(冗余版本)递交给识别的HARQ进程；指示识别的进程触发一个重传；如果接收到的上行调度对应CS-RNTI或接收到的上行调度是配置上行调度或接收到的上行调度对应C-RNTI且识别的HARQ进程被配置了配置上行调度，则如果配置了配置调度定时器，当执行传输时启动或重启所述配置调度定时器configuredGrantTimer。
需要说明的是，在本公开实施例中，每个HARQ进程支持一个传输块TB或两个传输块(在空分复用MIMO中支持两个传输块)。
需要说明的是，如果HARQ实体为较低优先级的上行调度(所述上行调度的PUSCH持续时间与优先级较高的上行调度的PUSCH持续时间重叠)生成/获取了MAC PDU并存储在缓存区中或者如果较低优先级的上行调度有数据要发送，则指示复用与组装过程在为优先级较高的上行调度生成MAC PDU时在其中包含一个缓存数据指示MAC CE或者触发低优先级数据指示。可选的，如果缓存数据指示被触发且未被取消，当MAC实体被分配了用于新传的上行资源时，指示复用和组装过程生成一个缓存数据指示MAC CE，取消触发的缓存数据指示。其中，所述较低优先级的上行调度有 数据要发送可以是HARQ实体通过向“决定上行调度优先级过程”获取的优先级确定，因此较低优先级的上行调度有数据要发送也可以描述为低优先级的上行调度的优先级不是为没有数据和/或没有数据和MAC CE发送而预定义的值，例如低优先级的上行调度的优先级大于0。所述缓存数据指示MAC CE中可以指示发生PUSCH持续时间重叠的低优先级上行调度是否有缓存数据或者指示低优先级的上行调度识别的HARQ进程的缓存区是否有缓存数据。例如，用位图表示，位图中的每位对应一个发生PUSCH持续时间重叠的低优先级上行调度，当所述上行调度对应的HARQ进程的缓存区有缓存数据，则对应的位被置为1(或0)，否则置为0(或1)。优选的，如果缓存数据指示MAC CE被包含在为动态调度生成的MAC PDU中，则将发生PUSCH持续时间重叠的配置调度按照配置调度标识由小到大(或从大到小)的顺序以此对应位图中从左到右(或从右到左)的位。例如，位图第0位对应发生PUSCH持续时间重叠的具有最小配置调度标识的配置调度，依次类推。如果缓存数据指示MAC CE被包含在为配置调度生成的MAC PDU中，则位图的第0位对应动态，第1位对应发生PUSCH持续时间重叠的具有最小配置调度标识的配置调度，依次类推。所述配置调度标识是基站通过RRC信令/消息为每个配置调度配置的，例如，包含在ConfiguredGrantConfig信元中，在配置相应的配置调度时配置。可选的，缓存数据指示MAC CE的优先级小于PHR MAC CE(包括Single Entry PHR MAC CE和Multiple Entry PHR MAC CE)大于来自逻辑信道的数据的优先级(来自UL-CCCH的数据除外)
下面具体描述在发生DG/CG或CG/CG冲突时用户设备UE的HARQ进程的执行的操作实施例。
在一个实施例中，如果HARQ实体请求存储一个传输块(TB)对应的MAC PDU或如果HARQ实体请求不触发新传或重传或如果HARQ进程没有接收到来自HARQ实体的触发新传或重传的指示，则HARQ进程执行以下操作至少一项：
1)存储接收来自HARQ实体对应于存储的MAC PDU的上行调度(store the uplink grant received from the HARQ entity for storing MAC PDU)；
2)不产生传输或重传(do not generate a transmission or retransmission)。
需要说明的是，在本公开中如未特别说明调度都是指上行调度，动态调度是指对某个服务小区来说在PDCCH上接收到MAC实体的C-RNTI或CS-RNTI的上行调度(an uplink grant for a serving cell is received on the PDCCH for the MAC entity’s C-RNTI or CS-RNTI)(换言之，在PDCCH上接收到的上行调度)，如果动态调度是针对MAC实体的CS-RNTI，那么NDI为1；配置调度就是配置上行调度(configured uplink grant)。
下面描述复用与组装(也可以是逻辑信道优先级过程LCP)过程在接受到多个上行调度时的处理方式实施例。
在一个实施例中，如果复用和组装过程接收到一个PUSCH持续时间与其他上行调度的PUSCH持续时间重叠的上行调度，且该上行调度的优先级更高，复用与组装过程已经为所述较低优先级的上行调度生成了MAC PDU，则将已经包含在为所述较低优先级的上行调度生成了MAC PDU的MAC控制元素CE(包括缓存状态报告BSR和功率余量报告PHR)包含在为该优先级较高的上行调度生成的MAC PDU中(如果其中包含BSR，则要重新计算并生成BSR)，如果所述较低优先级的上行调度生成的MAC PDU只包含MAC CE，则将所有MAC CE包含在为较高优先级的上行调度生成的MAC PDU中(所述MAC CE包括BSR、PHR、配置调度确认MAC CE)，并取消为所述较低优先级的上行调度生成的MAC PDU(即清空低优先级上行调度对应的HARQ进程的HARQ缓存区)，可选的，还停止所述较低优先级的上行调度对应的HARQ进程的配置调度定时器(如果正在运行)。
在一个实施例中，如果接收到一个服务小区的多个上行调度，先为具有较高优先级的上行调度生成MAC PDU且MAC CE(包括BSR、PHR、配置调度确认MAC CE，如果存在)包含在这个MAC PDU中。如果接收到的多个上行调度的优先级相同，如果其中包含动态调度，则为动态调度生成MAC PDU并在其中包含需要发送的MAC CE。
