具体实施方式
如背景技术所言，现有技术并未考虑采用PUR搜索空间窗时，可能带来的资源冲突问题。
在NR中，UE可以在RRC空闲态(idle)和RRC非活动态(inactive)中使用不连续接收(Discontinuous Reception，简称DRX)以便降低功耗。UE侦听每个DRX周期的一个寻呼时刻(Paging occasion，简称PO)。由于NR引入了波束管理的操作，单个PO的长度即是一个波束扫描周期，在扫描模式的所有波束中重复发送相同的寻呼消息。用于接收寻呼消息的波束的选择取决于UE实现。一个寻呼帧是一个无线帧，并且可以包含一个或多个PO，甚至寻呼帧为一个PO的起始点。寻呼帧的确定与长期演进(Long Term Evolution，简称LTE)中的计算方式类似。
当前NR系统中，在空闲态/非活动(idle/inactive)态下的UE想要发送上行/下行数据，需要通过随机接入过程进入连接态后才能发送上行/下行数据，“/”表示或。这种空闲/非活动态下的数据传输机制会增大RRC信令开销以及UE能耗，同时也增大了数据传输的时延。
为了减少空闲态下UE发送上行数据所带来的RRC信令开销与UE能耗，在窄带物联网(Narrow Band Internet of things，简称NB-IOT)系统中，引入了提前数据传输机制(Early Data Transmission，简称EDT)。EDT传输机制的本质在于，UE在发起随机接入过程中，利用第三消息(Message3，简称Msg3)携带上行数据以达到上行数据传输的目的，从而避免UE进入连接态。针对空闲态下的上行数据传输，该方式有效减少了RRC信令的开销与UE能耗，同时降低了UE传输时延。但是，由于Msg3所能携带的比特数有限，该方式只能上传一些小的上行数据包。
为了进一步减少UE在空闲态发送上行数据所带来的RRC信令 开销以及增大上行数据传输的速率，NB-IOT引入了周期性上行预配置资源(Preconfigure Uplink resource，简称PUR)，UE在PUR上可以直接发送上行数据，并在对应的上行预配置资源搜索空间窗(PUR search space window)接收重传调度信息或确认信息，如确认/否定确认(ACKnowledgement/Non-ACKnowledgement，简称ACK/NACK)，从而避免UE发起随机接入进入连接态过程。
然而，在空闲或非活动态，UE会根据测量准则自主进行同频/异频测量活动，“/”表示或。UE在进行异频测量时需要将射频调整到其他的频点，此时UE不能进行数据的接收或发送。当PUR关联的搜索空间窗与UE调整后的射频测量在时域上发生冲突，即上行预配置资源对应的下行搜索空间窗与基于同步信号块的测量时间配置(SS block based RRM measurement timing configuration，简称SMTC)在时域上重叠时，UE无法同时进行数据接收与测量。此时，UE无法接收ACK/NACK或者重传调度等信息，意味着上行预配置资源不能用来做数据发送。
由于在空闲或非活动态下，UE的测量活动是完全自主的，网络无法知道UE是在什么时刻进行同频/异频测量活动的。因此，当PUR搜索空间窗与UE的测量活动冲突时，UE在执行测量时无法进行数据的发送与接收，此时配置的上行预配置资源是资源浪费。
为解决上述技术问题，本发明实施例提供一种资源冲突处理方法，包括：判断PUR搜索空间窗与SMTC是否时域重叠；如果所述PUR搜索空间窗与SMTC时域重叠，那么当具有待传上行数据时，采用与所述PUR搜索空间窗关联的PUR发送所述待传上行数据；或者，如果所述PUR搜索空间窗与SMTC时域重叠，那么根据测量需求在所述SMTC进行测量。
在判定PUR搜索空间窗与SMTC时域重叠时，本发明实施例要么在终端具有上行数据时放弃与所述PUR搜索空间窗时域重叠的SMTC测量过程，要么释放与所述PUR搜索空间窗关联的上行预配 置资源，从而避免出现PUR搜索空间窗与SMTC之间的冲突问题，有利于减少上行预配置资源的浪费。
为使本发明的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
在为UE配置PUR及其关联的PUR搜索空间窗时，本领域技术人员并未考虑到该PUR搜索空间窗所用资源可能与其他下行资源发生资源冲突问题。本申请发明人经仔细研究发现，PUR搜索空间窗可能与SMTC时域重叠。当二者发生时域重叠时，将出现资源冲突等问题。
图1是本发明实施例的一种资源冲突处理方法的流程示意图。所述资源冲突处理方法可以应用于终端侧，例如由NR UE执行。具体而言，所述资源冲突处理方法可以包括以下步骤：
步骤S101，判断PUR搜索空间窗与SMTC是否时域重叠；
步骤S102，如果所述PUR搜索空间窗与SMTC时域重叠，那么当具有待传上行数据时，采用与所述PUR搜索空间窗关联的PUR发送所述待传上行数据；或者，如果所述PUR搜索空间窗与SMTC时域重叠，那么根据测量需求在所述SMTC进行测量。
更具体而言，在步骤S101中，UE在确定PUR搜索空间窗与SMTC的时域位置后，可以判断所述PUR搜索空间窗与SMTC是否时域重叠。如果所述PUR搜索空间窗与SMTC时域不重叠，那么UE可以基于PUR进行正常的数据上传。
在步骤S102中，如果所述PUR搜索空间窗与SMTC时域重叠，那么UE可以在具有待传上行数据时，采用与所述PUR搜索空间窗关联的PUR发送所述待传上行数据。或者，如果所述PUR搜索空间窗与SMTC时域重叠，那么UE可以根据测量需求在所述SMTC时间窗内进行测量。
具体实施中，如果UE具有待传上行数据，则UE可以采用与所 述PUR搜索空间窗关联的PUR发送所述待传上行数据，且不在与所述PUR搜索空间窗时域重叠的SMTC时间窗内进行测量。如果UE不具有待传上行数据，则UE可以根据测量需求确定是否需要进行测量，当需要测量时，UE可以在与所述PUR搜索空间窗时域重叠的SMTC时间窗内进行测量。
具体实施中，如果协议规定在与所述PUR搜索空间窗的SMTC时间窗内，UE可以根据测量需求进行测量，那么UE可以根据所述测量需求在所述SMTC时间窗内进行测量，且判定所述PUR搜索空间窗关联的PUR为失效资源。此时，UE和网络侧可以释放该PUR。例如，网络侧允许在与所述PUR搜索空间窗的SMTC时间窗内，UE可以根据测量需求进行测量。此时，如果UE需要测量，则可以在与所述PUR搜索空间窗的SMTC时间窗内进行测量。
作为一个变化实施例，如果所述PUR搜索空间窗与SMTC时域重叠，且满足同频/异频测量条件，那么UE可以在具有待传上行数据时，采用与所述PUR搜索空间窗关联的PUR发送所述待传上行数据，在所述SMTC期间不执行同频/异频测量。
如果所述PUR搜索空间窗与SMTC时域重叠，且不满足同频/异频测量条件，那么UE可以在具有待传上行数据时，采用与所述PUR搜索空间窗关联的PUR发送所述待传上行数据，且在所述SMTC期间可以执行服务小区的测量。
如果所述PUR搜索空间窗与SMTC时域重叠，且满足同频/异频测量条件，但UE不具有待传上行数据，那么UE可以根据测量需求在所述SMTC期间可以执行服务小区的测量，和/或，同频/异频测量。
作为另一个实施例，当满足所述同频/异频测量条件时，UE可以发送指示信息给网络侧基站。通过接收到的指示信息，网络侧基站可以得知UE将在与所述PUR搜索空间窗时域重叠的SMTC期间进行同频/异频测量。其中，所述指示信息用于表示终端启动同频/异频测量。
之后，如果所述PUR搜索空间窗与SMTC时域重叠，且满足同频/异频测量条件，则UE可以根据所述测量需求在所述SMTC时间窗内进行测量。
作为又一个实施例，网络侧可以预先向UE发送所述PUR的配置信息，所述配置信息包括测量间隙，所述测量间隙包含至少一个SMTC。之后，UE在接收到该配置信息后，可以得知测量间隙的时域位置。在此条件下，如果所述PUR搜索空间窗与所述测量间隙时域重叠，那么UE可以根据所述测量需求在所述SMTC期间进行测量。此外，UE可以判定所述PUR搜索空间窗关联的PUR为失效资源，该PUR可以释放掉。
图2是本发明实施例的又一种资源冲突处理方法的流程示意图。所述资源冲突处理方法可以由网络侧实施，例如，由网络侧基站实施。具体而言，所述资源冲突方法可以包括以下步骤：
步骤S201，确定PUR搜索空间窗与SMTC是否时域重叠；
步骤S202，如果所述PUR搜索空间窗与SMTC时域重叠，那么允许终端采用与所述PUR搜索空间窗关联的PUR发送上行数据；或者，如果所述PUR搜索空间窗与SMTC时域重叠，那么允许所述终端根据测量需求在所述SMTC进行测量。
更具体而言，网络侧基站可以在步骤S201中，确定PUR搜索空间窗与SMTC是否时域重叠。如果时域不重叠，则可以按照现有技术方案，利用PUR发送上行数据，并利用PUR搜索空间窗发送下行数据。在SMTC期间，UE可以根据测量需求进行测量。
如果所述PUR搜索空间窗与SMTC时域重叠，那么在步骤S202中，网络侧基站可以允许UE采用与所述PUR搜索空间窗关联的PUR发送上行数据。或者，如果所述PUR搜索空间窗与SMTC时域重叠，那么网络侧基站可以允许UE根据测量需求在所述SMTC进行测量。
具体实施中，当允许所述终端根据测量需求在所述SMTC进行 测量时，网络侧基站可以释放所述PUR搜索空间窗关联的PUR。
作为一个具体实施例，网络侧基站还可以接收UE上传的指示信息，所述指示信息可以用于表示终端启动同频/异频测量。之后，网络侧基站可以得知，即使接下来的SMTC与PUR搜索空间窗时域重叠，UE也将在接下来的SMTC期间进行同频/异频测量。
作为另一个具体实施例，在确定PUR搜索空间窗与SMTC是否时域重叠之前，网络侧可以发送所述PUR的配置信息，所述配置信息包括测量间隙，所述测量间隙包含所述SMTC。之后，UE可以在测量间隙与PUR搜索空间窗时域重叠时，根据测量需求进行测量。
本领域技术人员理解，所述步骤S201至步骤S202可以视为与上述图1所示实施例所述步骤S101至步骤S102相呼应的执行步骤，两者在具体的实现原理和逻辑上是相辅相成的。因而，本实施例中涉及名词、原理的解释可以参考图1所示实施例的相关描述，这里不再赘述。
下面以具体实施例进行详细阐述。
实施例1：与PUR搜索空间窗时域重叠的SMTC不用作测量。
图3是本发明实施例的一种具体实施方式的流程示意图。参考图3，当PUR搜索空间窗(图中以虚线空白格表示)与SMTC(图中以斜条纹格表示)重叠时，重叠的SMTC不用作测量(图中以“×”表示放弃在该SMTC时间窗内的测量)。此时，UE可以正常地利用该上行预配置资源(即PUR，图中以实线空白格表示；且利用“√”表示该PUR资源为有效资源)进行数据的发送，且可以在PUR搜索空间窗接收下行信令等信息。
实施例2：与SMTC时域重叠的PUR搜索空间窗对应的PUR失效。
图4是本发明实施例的又一种具体实施方式的流程示意图。参考图4，当PUR搜索空间窗(图中以虚线空白格表示)与SMTC(图中 以斜条纹格表示)重叠时，网络允许UE在SMTC进行测量。相应地，与SMTC重叠的PUR搜索空间窗不再传输下行信令等信息。与所述PUR搜索空间窗关联的PUR不能用来做数据传输，UE可以释放所述PUR。网络侧基站(如gNB)在所述PUR上不需要做数据接收。其中，图中以“×”表示UE释放PUR；“√”表示保留SMTC，允许UE在SMTC进行测量。
实施例3：当满足同频/异频(intra-frequency/inter-frequency)测量条件，与SMTC时域重叠的PUR搜索空间窗对应的PUR失效。
图5是本发明实施例的又一种具体实施方式的流程示意图。参考图5，当PUR搜索空间窗(图中以虚线空白格表示)与SMTC(图中以斜条纹格表示)重叠，且在满足同频/异频测量条件时，网络允许UE在SMTC进行测量。所述满足同频/异频测量条件指的是无线资源所在频点的信道质量低于预设阈值。例如，在NR系统中，所述满足同频/异频测量条件指的是当服务小区的信号质量低于同频测量门限/异频测量门限值。
本领域技术人员理解，在空闲/非活动态，UE的同频/异频测量活动服从测量准则，其中，“/”表示或。当UE满足同频/异频测量条件时，才有机会执行同频/异频测量。为了解决测量活动与PUR搜索空间窗的时域冲突问题，当UE满足同频/异频测量条件时，UE可以发送指示信息，所述指示信息用于告知网络UE将在与PUR搜索空间窗时域重叠的SMTC执行同频/异频测量。相应地，与所述SMTC时域重叠的PUR搜索空间窗关联的PUR失效，UE和网络可以释放该PUR(图中以“×”表示释放该PUR)。
继续参考图5，当PUR搜索空间窗与SMTC时域重叠，且不满足同频/异频测量条件时，UE可以在与PUR搜索空间窗重叠的SMTC进行服务小区测量，且可以在具有待传上行数据时，基于与所述PUR搜索空间窗关联的PUR传输所述待传上行数据。其中，图5中以“√”表示保留SMTC，以在该SMTC进行测量。
实施例4：当满足同频/异频测量条件时，与PUR搜索空间窗时域重叠的SMTC不能用作测量
图6是本发明实施例的又一种具体实施方式的流程示意图。参考图6，当PUR搜索空间窗(图中以虚线空白格表示)与SMTC(图中以斜条纹格表示)重叠，即使满足同频/异频测量条件，UE也不在所述SMTC进行测量。也即，无论UE是否满足同频/异频测量条件，在与PUR搜索空间窗时域重叠的SMTC期间，如果UE具有待传上行数据将在PUR上报给网络侧基站，那么UE就不执行测量。
当PUR搜索空间窗与SMTC时域重叠时，如果UE具有待传上行数据，则UE可以在与SMTC时域重叠的PUR搜索空间窗对应的PUR发送所述待传上行数据。图6中，以“×”表示保留PUR，使得可以在该PUR传输所述待传上行数据；以“√”表示放弃SMTC，不进行测量。否则，如果UE不具有待传上行数据，不使用与SMTC时域重叠的PUR搜索空间窗关联的PUR，那么当该UE具有测量需求时，可以在与该PUR搜索空间窗时域重叠的SMTC时间窗内进行测量。
实施例5：引入测量间隙(measurement gap)，与测量间隙时域重叠的上行预配置资源搜索空间窗对应的PUR不同用作数据发送。
具体而言，网络侧可以预先为UE在PUR配置中添加测量间隙，所述测量间隙至少包含一个SMTC。图7是本发明实施例的又一种具体实施方式的流程示意图。参考图7，当所述测量间隙与PUR搜索空间窗时域重叠时，UE不在与测量间隙时域重叠的PUR搜索空间窗对应的PUR中发送上行数据。此时，PUR可以释放掉(图中以“×”表示)。
继续参考图7，当所述测量间隙不包含的SMTC与PUR搜索空间窗时域重叠时，UE仍然可以在所述PUR搜索空间窗关联的PUR传输上行数据，且可以在该SMTC期间进行测量。
继续参考图7，当所述测量间隙不与PUR搜索空间窗时域重叠，但不在所述测量间隙的其他SMTC与PUR重叠时，UE仍然可以在所述PUR搜索空间窗关联的PUR传输上行数据，且可以在该其他SMTC期间进行测量。
关于图3至图7的具体实施例的工作原理、工作方式的更多内容，可以参照图1中的相关描述，这里不再赘述。
综上所述，本发明实施例可使得UE与网络在PUR搜索空间窗与SMTC的冲突时达成一致，解决PUR搜索空间窗与SMTC的冲突问题，避免上行预配置资源的浪费。

具体而言，所述资源冲突处理装置8可以包括：判断模块81，用于判断PUR搜索空间窗与SMTC是否时域重叠；发送测量模块82，如果所述PUR搜索空间窗与SMTC时域重叠，那么所述发送测量模块82用于当具有待传上行数据时，采用与所述PUR搜索空间窗关联的PUR发送所述待传上行数据；或者，如果所述PUR搜索空间窗与SMTC时域重叠，那么所述发送测量模块82用于根据测量需求在所述SMTC进行测量。
