Description

一种信息处理方法和通信设备 技术领域
本申请实施例涉及通信领域,尤其涉及一种信息处理方法和通信设备。
背景技术
演进型长期演进(long term evolution-advanced,LTE-A)系统是长期演进(long term evolution,LTE)系统的改进版本,LTE-A系统在一段时间内仍将为用户设备(user equipment,UE)继续提供无线通信服务,基于LTE-A系统实现的通信系统有多种,例如增强型机器类通信(enhanced machine type communication,eMTC)系统及其他演化系统,eMTC系统仍在LTE系统提供的频段中进行工作。
为了节省功耗,降低成本,eMTC终端的工作带宽通常可能较小,例如,eMTC终端的工作带宽小于LTE系统的工作带宽,例如eMTC终端的工作带宽可以是一个窄带,一个窄带包括6个连续的物理资源块(physical resource block,PRB),一个物理资源块包括12个子载波。
在LTE系统中,基站可以向用户设备发送下行控制信息,但是用户设备无法确定基站是否发送了关于用户设备本身的下行控制信息,同时也不知道下行控制信息的内容,所以用户设备需要在基站确定的搜索空间的时频资源上进行盲检测,用户设备通过监测搜索空间(search space,SS)确定是否有基站发送给该用户设备的下行控制信息。其中,eMTC终端的搜索空间是周期出现的,并且该搜索空间的起始位置由基站配置。
对于某些业务,为了降低资源开销和数据传输时延,用户设备可在预先配置的资源上传输该业务,也就是不需要动态的下行控制信息调度,用户设备在预先配置的资源上传输信号,该预先配置的资源可以称为预先配置上行链路资源(preconfigured uplink resource,PUR)。用户设备需要接收基站对用户设备的反馈PUR传输是否成功的反馈信息,用户设备可监测基站用于反馈PUR传输是否成功的控制信道所在的搜索空间,例如,搜索空间占用的时间段可以是搜索空间窗(search space window),用户设备需要监测该搜索空间窗。
用户设备确定搜索空间窗的起始位置可以是PUR结束后的第4个子帧。这种确定搜索空间窗的方案并不适用于支持提前终止(early termination)传输的场景,因为对于支持提前终止传输的场景,如果在PUR结束后的第4个子帧开始监测搜索空间窗,那么用户设备的上行信号传输可能已经结束,此时无法监测到搜索空间窗。
因此,目前针对支持提前终止传输的场景下如何确定搜索空间窗的起始位置,还没有给出合适的解决方案。
发明内容
本申请实施例提供了一种信息处理方法和通信设备,用于实现第一通信设备对第一时间窗的检测,避免无法检测到时间窗的问题。
为解决上述技术问题,本申请实施例提供以下技术方案:
第一方面,本申请实施例提供一种信息处理方法,包括:第一通信设备从第二通信设备接收第一信息;所述第一通信设备根据所述第一信息确定第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元,或者所述第一时间窗的起始位置为所述第一资源的结束位置之后的第K2个时间单元,所述第一资源为所述第一通信设备传输数据所使用的资源,所述K1和所述K2为正整数;所述第一通信设备按照确定的所述第一时间窗的起始位置检测所述第二通信设备发送的控制信息。在该方案中,第二通信设备可以通过第一信息指示第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元,或者第一时间窗的起始位置为第一资源的结束位置之后的第K2个时间单元,因此第一通信设备可以按照第二通信设备的指示确定出第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元,或者第一时间窗的起始位置为第一资源的结束位置之后的第K2个时间单元,第一时间窗的起始位置可以由第二通信设备指示给第一通信设备,该第一时间窗的起始位置可以位于第一资源的起始位置之后,从而适用于提前终止传输场景下第一通信设备对第一时间窗的检测,避免无法检测到时间窗的问题,该第一时间窗的起始位置除了可以位于第一资源的起始位置之后,也可以位于第一资源的结束位置之后,提高了第一通信设备检测第一时间窗的效率。
在一种可能的实现方式中,所述第一通信设备根据所述第一信息确定所述第一时间窗的起始位置为所述第一资源的起始位置之后的第K1个时间单元,或者为所述第一资源的结束位置之后的第K2个时间单元,包括:所述第一信息包括第一数值,所述第一通信设备确定所述第一时间窗的起始位置为所述第一资源的起始位置之后的第K1个时间单元,所述K1是所述第一通信设备根据所述第一数值确定的;或者,所述第一信息不包括所述第一数值,所述第一通信设备确定所述第一时间窗的起始位置为所述第一资源的结束位置之后的第K2个时间单元,所述K2是预先规定的数值,或者所述K2是从所述第二通信设备接收到的数值。在该方案中,第一信息指示第一时间窗的起始位置具有多种方式,例如第一信息可以携带第一数值,或者第一信息可以不携带第一数值,第二通信设备根据第一信息是否携带第一数值可以指示第一时间窗的起始位置的两种实现方式,例如第二通信设备确定第一时间窗的起始位置为第一资源的起始位置之后的位置,第二通信设备确定第一信息包括第一数值;或者,第二通信设备确定第一时间窗的起始位置为第一资源的结束位置之后的位置,第二通信设备确定第一信息不包括第一数值,则第一通信设备接收到第一信息之后,只需要检测第一信息中是否携带前述的第一数值,就可以确定第一时间窗的起始位置为上述两种实现方式中的哪一种。本申请实施例中该第一数值可以称为第一参量,该第一数值可以是根据K1确定第一数值,例如第二通信设备预先确定K1,然后根据该K1的取值来确定第一数值,例如K1和第一数值具有一一对应关系,第二通信设备可以根据该对应关系确定出第一数值。
在一种可能的实现方式中,所述第一数值为所述K1。即第二通信设备可以确定第一数值等于K1,因此若第一信息中携带第一数值,则第一通信设备可以从第一信息中获取到第一数值,第一通信设备还可以确定K1的取值为第一信息中携带的第一数值,从而第一通信设备确定第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元。
在一种可能的实现方式中,所述第一数值为数值M1,所述K1由所述M1和所述第一资 源的配置参数确定。其中,第一资源的配置参数是指针对第一资源配置的参数,例如第一资源的配置参数可以是第二通信设备为第一通信设备使用第一资源而配置的参数。第一信息中可以携带数值M1,则第一通信设备从第一信息中获取到M1之后,第一通信设备可以根据预先确定的K1生成方式,使用M1和第一资源的配置参数来计算出K1,从而第一通信设备确定第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元。
在一种可能的实现方式中,所述第一资源的配置参数包括:所述第一资源的周期N1、所述第一资源的重复次数N2、所述第一资源包括的时间单元个数N3;所述K1满足M1×N1+A1,或者M1×N2+A2,或者M1×N3+A3;其中,所述A1、所述A2和所述A3为预先规定的数值;或者,所述A1、所述A2或所述A3是从所述第二通信设备接收到的数值。在该方案中,K1可以满足如下三种关系中的至少一种:M1×N1+A1,或者M1×N2+A2,或者M1×N3+A3,其中,A1、A2和A3为预先规定的数值,或者,A1、A2或A3是第一通信设备从第二通信设备接收到的数值,例如A1至A3是预先确定的偏移量。A1、A2、A3还可以是第一通信设备从第二通信设备接收到的数值,例如第一信息中可以携带A1、A2、A3,不限定的是,还可以不在第一信息中携带A1、A2、A3,通过其它的物理层信令或者高层信令携带A1、A2、A3。在计算出M1×N1之后按照A1进行偏移,可以得到K1,同理,可以对M1×N2之后按照A2进行偏移得到K1,对M1×N3之后按照A3进行偏移得到K1。本申请实施例中,第二通信设备通过第一信息向第一通信设备指示M1,从而第一通信设备可以计算出K1,从而第一通信设备确定第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元。
在一种可能的实现方式中,所述第一通信设备根据所述第一信息确定所述第一时间窗的起始位置为所述第一资源的起始位置之后的第K1个时间单元,或者为所述第一资源的结束位置之后的第K2个时间单元,包括:所述第一信息指示所述第一通信设备能够提前终止传输,所述第一通信设备确定所述第一时间窗的起始位置为所述第一资源的起始位置之后的第K1个时间单元,所述K1是预先规定的数值,或者所述K1是从所述第二通信设备接收到的数值;所述第一信息指示所述第一通信设备不能够提前终止传输,所述第一通信设备确定所述第一时间窗的起始位置为所述第一资源的结束位置之后的第K2个时间单元,所述K2是预先规定的数值,或者所述K2是从所述第二通信设备接收到的数值。在该方案中,其中,在提前终止传输的场景下,第二通信设备还需要指示第一通信设备是否能够提前终止传输,则本申请实施例中是否能够提前终止传输可以与第一时间窗的起始位置相关联,第二通信设备只需要向第一通信设备指示是否能够提前终止传输,则第一通信设备接收到第一信息之后,第一通信设备可以获取到第二通信设备指示的是否能够提前终止传输,第一通信设备根据是否能够提前终止传输与第一时间窗的起始位置的关联关系确定第一时间窗的起始位置为第一资源的起始位置之后的位置,或者第一时间窗的起始位置为第一资源的结束位置之后的位置。
在一种可能的实现方式中,所述方法还包括:所述第一通信设备从所述第二通信设备接收第二信息,所述第二信息用于指示所述第一通信设备的搜索空间在所述第一时间窗内的起始位置,所述第一时间窗包括一个或多个搜索空间;所述第一通信设备根据所述第二信息确定所述第一通信设备的搜索空间在所述第一时间窗内的起始位置。在该方案中,在 第一时间窗内可以包括一个或多个的搜索空间。第一通信设备需要检测搜索空间在第一时间窗内的起始位置,第二通信设备可以确定第一通信设备的搜索空间在第一时间窗内的起始位置,然后第二通信设备向第一通信设备发送第二信息,从而第一通信设备可以接收到第二信息之后,根据该第二信息的指示确定第一通信设备的搜索空间在第一时间窗内的起始位置。例如第一通信设备的搜索空间在第一时间窗内的起始位置可以是第一时间窗的起始位置,或者第一通信设备的搜索空间在第一时间窗内的起始位置可以是第一时间窗的起始位置偏移一个第二数值之后的一个位置。例如第二数值可以是根据第一通信设备的DMRS配置参数和/或第一资源的配置信息参数确定的,因此在多个通信设备共享第一资源的场景下,每个通信设备的搜索空间在第一时间窗内的起始位置是不相同的,避免多个通信设备之间的冲突。
第二方面,本申请实施例提供一种信息处理方法,包括:第二通信设备确定用于发送控制信息的第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元,或者所述第一时间窗的起始位置为所述第一资源的结束位置之后的第K2个时间单元,其中,所述第一资源为第一通信设备传输数据所使用的资源,所述K1和所述K2为正整数;所述第二通信设备向所述第一通信设备发送第一信息,所述第一信息用于所述第一通信设备确定所述第一时间窗的起始位置;所述第二通信设备按照所述第一时间窗的起始位置向所述第一通信设备发送控制信息。在该方案中,第二通信设备可以通过第一信息指示第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元,或者第一时间窗的起始位置为第一资源的结束位置之后的第K2个时间单元,因此第一通信设备可以按照第二通信设备的指示确定出第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元,或者第一时间窗的起始位置为第一资源的结束位置之后的第K2个时间单元,第一时间窗的起始位置可以由第二通信设备指示给第一通信设备,该第一时间窗的起始位置可以位于第一资源的起始位置之后,从而适用于提前终止传输场景下第一通信设备对第一时间窗的检测,避免无法检测到时间窗的问题,该第一时间窗的起始位置除了可以位于第一资源的起始位置之后,也可以位于第一资源的结束位置之后,提高了第一通信设备检测第一时间窗的效率。
在一种可能的实现方式中,所述第二通信设备向所述第一通信设备发送第一信息之前,所述方法还包括:所述第二通信设备确定所述第一时间窗的起始位置为所述第一资源的起始位置之后的位置,所述第二通信设备根据所述K1确定第一数值,所述第二通信设备确定所述第一信息包括所述第一数值;或者,所述第二通信设备确定所述第一时间窗的起始位置为所述第一资源的结束位置之后的位置,所述第二通信设备确定所述第一信息不包括第一数值。在该方案中,第一信息指示第一时间窗的起始位置具有多种方式,例如第一信息可以携带第一数值,或者第一信息可以不携带第一数值,第二通信设备根据第一信息是否携带第一数值可以指示第一时间窗的起始位置的两种实现方式,例如第二通信设备确定第一时间窗的起始位置为第一资源的起始位置之后的位置,第二通信设备确定第一信息包括第一数值;或者,第二通信设备确定第一时间窗的起始位置为第一资源的结束位置之后的位置,第二通信设备确定第一信息不包括第一数值,则第一通信设备接收到第一信息之后,只需要检测第一信息中是否携带前述的第一数值,就可以确定第一时间窗的起始位置。

请参阅图2所示,为本申请实施例提供的一种信息处理方法的交互流程示意图,例如第一通信设备可以是前述的终端设备,第二通信设备可以是前述的网络设备。本申请实施例提供的信息处理方法,后续步骤201至步骤203从网络设备一侧进行说明,后续步骤211至步骤213从终端设备一侧进行说明,主要包括如下步骤:
201、第二通信设备确定用于发送控制信息的第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元,或者第一时间窗的起始位置为第一资源的结束位置之后的第K2个时间单元,其中,第一资源为第一通信设备传输数据所使用的资源,K1和K2为正整数。
在本申请实施例中,第一时间窗用于第二通信设备发送控制信息,第二通信设备需要确定第一时间窗的起始位置,其中,时间窗也可以称为时间段(time duration,或者time period),例如,时间窗可以是搜索空间窗,或者检测(monitoring)时间窗,或者控制信息监测(monitoring)时间窗。第一搜索时间窗是指在该时间段内(时间窗内),第二通信设备可能会发送控制信息,也就是第一通信设备在该时间段内监测第二通信设备发送的控制信息。在第一时间窗内可以包括一个或多个的搜索空间,第二通信设备可以在第一时间窗内的该搜索空间中向第一通信设备发送控制信息。搜索空间为时间资源和频率资源的集合,第二通信设备可以在搜索空间所分配的时间和频率资源中向第一通信设备发送控制信息。第一时间窗的起始位置是第一通信设备可以检测控制信息的起始位置,即第一通信设备可以在第一时间窗的起始位置检测控制信息或者检测搜索空间,或者,第一通信设备可以在第一时间窗的起始位置开始在搜索空间中检测控制信息。
本申请实施例中,第二通信设备确定第一时间窗的起始位置具有多种实现方式,例如第一时间窗的起始位置可以由第一资源来确定,其中,第一资源为第一通信设备传输数据 所使用的资源,第一资源可以是第二通信设备预先配置的资源,例如第一资源可以是前述的PUR。第一资源可以是用户特定的预配置资源,该第一资源还可以是多个用户共享的预配置资源。第一资源具有起始位置和结束位置,其中,第一资源的起始位置是指第二通信设备开始发送数据的第一资源的时间和/或频率位置,第一资源的结束位置是指第二通信设备结束发送第一资源的时间和/或频率位置。又如,第一资源的起始位置是指的第一资源包括的第一个时间单元或第一资源包括的第一个时间单元的起始位置,第一资源的结束位置是指第一资源包括的最后一个时间单元或第一资源包括的最后一个时间单元的结束位置。
需要说明的是,第一资源可以为第一通信设备传输上行数据所使用的资源;或者第一资源可以为预配置上行链路资源(preconfigured uplink resource,PUR),PUR仅是一种示例性命名,其实质是网络设备通过配置该资源,第一通信设备可以在不需要第二通信设备动态调度或下行控制信息调度的情况下在该资源上进行上行信息的传输,该资源也可以命名为其他名称,如配置授权资源,应理解,若该配置授权资源也可以实现本申请实施例中的预配置上行资源所实现的功能,也可以将配置授权资源理解为本申请实施例中的预配置上行资源。
本申请实施例中,第一时间窗的起始位置可以是第一资源的起始位置之后的某个时间单元,例如第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元,K1表示时间单元的个数,例如,K1等于6,则说明第一时间窗的起始位置为第一资源的起始位置之后的第6个时间单元。
在本申请的一些实施例中,第一资源的起始位置之后的第K1个时间单元,可以指的是第一资源的起始位置之后的第一数值个时间单元后的第一时间单元,第一数值为X1,第一数值可以是第二通信设备发送给第一通信设备的或预定义的,第一通信设备确定从第一资源的起始位置之后间隔X1个时间单元后的第一时间单元是第一资源的起始位置之后的第K1个时间单元;或者第一资源的起始位置之后的X1个时间单元后的第一个有效时间单元,第一通信设备确定从第一资源的起始位置之后间隔X1个时间单元后的第一个有效时间单元是第一资源的起始位置之后的第K1个时间单元,有效时间单元可以为减少带宽、低复杂度、覆盖增强(Bandwidth-reduced Low-complexity and Coverage Enhanced、BL/CE)子帧。
另外,第一时间窗的起始位置还可以是第一资源的结束位置之后的某个时间单元,例如第一时间窗的起始位置为第一资源的结束位置之后的第K2个时间单元,K2表示时间单元的个数,例如,K2等于4,则说明第一时间窗的起始位置为第一资源的起始位置之后的第4个时间单元。又如,K1可以等于K2,又如,K1还可以不等于K2,具体需要根据应用场景确定K1和K2的取值。
在本申请的一些实施例中,第一资源的结束位置之后的第K2个时间单元可以指的是第一资源的结束位置之后的X2个时间单元后的第一时间单元,第一数值为X2,第一数值可以是第二通信设备发送给第一通信设备的或预定义的,第一通信设备确定从第一资源的结束位置之后间隔X2个时间单元后的第一时间单元是第一资源的结束位置之后的第K2个时间单元;或者第一资源的结束位置之后的X2个时间单元后的第一个有效时间单元,第一通信设备确定从第一资源的结束位置之后间隔X2个时间单元后的第一个有效时间单元是第 一资源的结束位置之后的第K2个时间单元,有效时间单元可以为BL/CE子帧。
本申请实施例中,第一时间窗的起始位置可以位于第一资源的起始位置之后,从而适用于提前终止传输场景下第一通信设备对第一时间窗的检测,即第一通信设备可以在第一资源传输开始时就进行第一时间窗的检测,避免无法检测到时间窗的问题,该第一时间窗的起始位置除了可以位于第一资源的起始位置之后,也可以位于第一资源的结束位置之后,提高了第一通信设备检测第一时间窗的效率,提高了第一时间窗配置的灵活性。
202、第二通信设备向第一通信设备发送第一信息,第一信息用于第一通信设备确定第一时间窗的起始位置。
在本申请实施例中,第二通信设备通过前述步骤201确定第一信息之后,第二通信设备可以向第一通信设备发送第一信息,从而第一通信设备可以从第二通信设备接收到该第一信息,第通信设备解析该第一信息可以确定出第二通信设备指示的第一时间窗的起始位置。
在本申请的一些实施例中,步骤202第二通信设备向第一通信设备发送第一信息之前,本申请实施例提供的信息处理方法还包括如下步骤:
第二通信设备确定第一时间窗的起始位置为第一资源的起始位置之后的位置,第二通信设备根据K1确定第一数值,第二通信设备确定第一信息包括第一数值;或者,
第二通信设备确定第一时间窗的起始位置为第一资源的结束位置之后的位置,第二通信设备确定第一信息不包括第一数值。
其中,第一信息指示第一时间窗的起始位置具有多种方式,例如第一信息可以携带第一数值,或者第一信息可以不携带第一数值,第二通信设备根据第一信息是否携带第一数值可以指示第一时间窗的起始位置的两种实现方式,例如第二通信设备确定第一时间窗的起始位置为第一资源的起始位置之后的位置,第二通信设备确定第一信息包括第一数值;或者,第二通信设备确定第一时间窗的起始位置为第一资源的结束位置之后的位置,第二通信设备确定第一信息不包括第一数值,则第一通信设备接收到第一信息之后,只需要检测第一信息中是否携带前述的第一数值,就可以确定第一时间窗的起始位置为上述两种实现方式中的哪一种。本申请实施例中该第一数值可以称为第一参量,该第一参量可以是根据K1确定的,例如第二通信设备预先确定K1,然后根据该K1的取值来确定第一参量,例如K1和第一参量具有一一对应关系,第二通信设备可以根据该对应关系确定出第一参量。
进一步的,在本申请的一些实施例中,第一数值为K1,即第二通信设备可以确定第一数值等于K1,因此若第一信息中携带第一数值,则第一通信设备可以从第一信息中获取到第一数值,第一通信设备还可以确定K1的取值为第一信息中携带的第一数值,从而第一通信设备确定第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元。
在本申请的一些实施例中,第一数值为X1,第一数值可以是第二通信设备发送给第一通信设备的,第一通信设备确定从第一资源的起始位置之后间隔X1个时间单元后的第一时间单元是第一资源的起始位置之后的第K1个时间单元;或者第一资源的起始位置之后的X1个时间单元后的第一个有效时间单元,第一通信设备确定从第一资源的起始位置之后间隔X1个时间单元后的第一个有效时间单元是第一资源的起始位置之后的第K1个时间单元,有效时间单元可以为BL/CE子帧。
在本申请的另一些实施例中,第一数值为数值M1,M1为大于或等于零,且小于或等于1的数。K1由M1和第一资源的配置参数确定。其中,第一资源的配置参数是指针对第一资源配置的参数,例如第一资源的配置参数可以是第二通信设备为第一通信设备使用第一资源而配置的参数。第一信息中可以携带数值M1,则第一通信设备从第一信息中获取到M1之后,第一通信设备可以根据预先确定的K1或X1生成方式,使用M1和第一资源的配置参数来计算出K1,从而第一通信设备确定第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元。
进一步的,在本申请的一些实施例中,第一资源的配置参数包括如下参数中的至少一种:第一资源的周期N1、第一资源的重复次数N2、第一资源包括的时间单元个数N3。其中,N1可以是第二通信设备配置的第一资源的周期,N2是第二通信设备配置的第一资源的重复次数,N3是第二通信设备配置的第一资源包括的时间单元个数,则第一通信设备可以使用上述的N1、N2、或者N3,按照预先确定的K1生成方式得到K1。
例如K1可以满足如下三种关系中的至少一种:M1×N1+A1,或者M1×N2+A2,或者M1×N3+A3,其中,A1、A2和A3为预先规定的数值,或者,A1、A2或A3是第一通信设备从第二通信设备接收到的数值,例如A1至A3是预先确定的偏移量。又如,X1可以满足如下三种关系中的至少一种:M1×N1+A1,或者M1×N2+A2,或者M1×N3+A3。例如,在计算出M1×N1之后按照A1进行偏移,可以得到K1,同理,可以对M1×N2之后按照A2进行偏移得到K1,对M1×N3之后按照A3进行偏移得到K1。本申请实施例中,第二通信设备通过第一信息向第一通信设备指示M1,从而第一通信设备可以计算出K1,从而第一通信设备确定第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元。
需要说明的是,M1为大于或等于零,且小于或等于1的数,从而通过上述M1×N1+A1,或者M1×N2+A2,或者M1×N3+A3等方式计算出K1,那么当第一通信设备的传输信道质量较差时,第一通信设备需要多次进行重复传输之后才有可能成功传输,目前第一通信设备还需要在PUR结束后的第4个子帧开始监测搜索空间窗,这就会导致第一通信设备在接收到第二通信设备的下行控制信息之前需要监测很长时间的搜索空间窗,极大浪费了第一通信设备的功耗。由于M1为大于零小于或等于1的数,因此在第一资源的起始位置之后的第M1×N1+A1,或者M1×N2+A2,或者M1×N3+A3个时间单元才开始检测第一时间窗,从而不会浪费第一通信设备的功耗。
不限定的是,基于上述计算K1或X1的方式,还可以采用其它类似的方式,例如K1或X1满足M1×(N1+A1),或者M1×(N2+A2),或者M1×(N3+A3),对于A1至A3的取值不做限定。
在本申请的另一些实施例中,第一数值为数值M1,M1为大于或等于零,且小于或等于1的数。X1由M1和第一资源的配置参数确定。其中,第一资源的配置参数是指针对第一资源配置的参数,例如第一资源的配置参数可以是第二通信设备为第一通信设备使用第一资源而配置的参数。第一信息中可以携带数值M1,则第一通信设备从第一信息中获取到M1之后,第一通信设备可以根据预先确定的K1或X1生成方式,使用M1和第一资源的配置参数来计算出X1,从而第一通信设备确定第一时间窗的起始位置为第一资源的起始位置之后的X1个时间单元后的第一个有效时间单元也就是第K1个时间单元。第一资源的起始位置 之后间隔X1个时间单元后的第一时间单元是第一资源的起始位置之后的第K1个时间单元;或者第一资源的起始位置之后的X1个时间单元后的第一个有效时间单元,第一通信设备确定从第一资源的起始位置之后间隔X1个时间单元后的第一个有效时间单元是第一资源的起始位置之后的第K1个时间单元,有效时间单元可以为BL/CE子帧。
进一步的,在本申请的一些实施例中,第一资源的配置参数包括如下参数中的至少一种:第一资源的周期N1、第一资源的重复次数N2、第一资源包括的时间单元个数N3。其中,N1可以是第二通信设备配置的第一资源的周期,N2是第二通信设备配置的第一资源的重复次数,N3是第二通信设备配置的第一资源包括的时间单元个数,则第一通信设备可以使用上述的N1、N2、或者N3,按照预先确定的X1生成方式得到X1。
如,X1可以满足如下三种关系中的至少一种:M1×N1+A1,或者M1×N2+A2,或者M1×N3+A3。例如,在计算出M1×N1之后按照A1进行偏移,可以得到X1,同理,可以对M1×N2之后按照A2进行偏移得到X1,对M1×N3之后按照A3进行偏移得到X1。本申请实施例中,第二通信设备通过第一信息向第一通信设备指示M1,从而第一通信设备可以计算出K1,从而第一通信设备确定第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元。
需要说明的是,M1为大于或等于零,且小于或等于1的数,从而通过上述M1×N1+A1,或者M1×N2+A2,或者M1×N3+A3等方式计算出X1,那么当第一通信设备的传输信道质量较差时,第一通信设备需要多次进行重复传输之后才有可能成功传输,目前第一通信设备还需要在PUR结束后的第4个子帧开始监测搜索空间窗,这就会导致第一通信设备在接收到第二通信设备的下行控制信息之前需要监测很长时间的搜索空间窗,极大浪费了第一通信设备的功耗。由于M1为大于零小于或等于1的数,因此在第一资源的起始位置之后的M1×N1+A1,或者M1×N2+A2,或者M1×N3+A3个时间单元后的第一个有效子帧才开始检测第一时间窗,从而不会浪费第一通信设备的功耗。
不限定的是,基于上述计算X1的方式,还可以采用其它类似的方式,例如X1满足M1×(N1+A1),或者M1×(N2+A2),或者M1×(N3+A3),对于A1至A3的取值不做限定。
在本申请的一些实施例中,步骤202第二通信设备向第一通信设备发送第一信息之前,本申请实施例提供的信息处理方法还包括如下步骤:
第二通信设备确定第一信息用于指示第一通信设备能够提前终止传输,第二通信设备确定第一时间窗的起始位置为第一资源的起始位置之后的位置;或者,
第二通信设备确定第一信息用于指示第一通信设备不能够提前终止传输,第二通信设备确定第一时间窗的起始位置为第一资源的结束位置之后的位置。
其中,在提前终止传输的场景下,第二通信设备还需要指示第一通信设备是否能够提前终止传输,则本申请实施例中是否能够提前终止传输可以与第一时间窗的起始位置相关联,第二通信设备只需要向第一通信设备指示是否能够提前终止传输,则第一通信设备接收到第一信息之后,第一通信设备可以获取到第二通信设备指示的是否能够提前终止传输,第一通信设备根据是否能够提前终止传输与第一时间窗的起始位置的关联关系确定第一时间窗的起始位置为第一资源的起始位置之后的位置,或者第一时间窗的起始位置为第一资源的结束位置之后的位置。
本申请实施例中,“是否能够提前终止传输”也可以称为“是否使能提前终止传输”,使能提前终止也可以理解为第二通信设备(E-UTRAN,evolved universal terrestrial radio access netword)指示第二通信设备(E-UTRAN)可能会针对一个新的传输发送上行HARQ-ACK(hybrid automatic repeat request-acknowledge)反馈或者是上行授权来提前终止PUSCH传输,或者是一个显式的PUSCH(physical uplink shared channel)传输完成的确认。第二通信设备只需要指示是否使能了提前终止传输功能,第一通信设备就可以确定出第一时间窗的起始位置,因此不需要第二通信设备再单独指示第一时间窗的起始位置,减少了信令开销,提升通信系统的性能。
在本申请的一些实施例中,第一信息还可以是第二通信设备生成的用于指示第一时间窗的起始位置的专用信息,例如,第一信息指示第一时间窗的起始位置为第一资源的起始位置之后的位置;或者,第一信息指示第一时间窗的起始位置为第一资源的结束位置之后的位置。则第一通信设备可以从第二通信设备接收到该第一信息,第一通信设备按照第一信息携带的指示内容确定第一时间窗的起始位置为第一资源的起始位置之后的位置,或第一时间窗的起始位置为第一资源的结束位置之后的位置。
在多个第一通信设备共享第一资源的场景下,第一资源可以是多个用户共享的预配置资源,例如共享第一资源的场景可以是共享PUR场景,很多个用户共享一个PUR资源,如果搜索空间窗的起始位置都是PUR结束后的第4个子帧,会导致多个用户的搜索空间的碰撞,降低了控制信道的可靠性,浪费用户功率和系统资源。
在本申请的一些实施例中,在第一资源的共享场景下,每个通信设备的解调参考信号(demodulation reference signal,DMRS)索引,和/或每个通信设备的资源索引是不相同的,因此第二通信设备可以使用DMRS索引和/或资源索引来指示每个通信设备可用的第一时间窗的起始位置。具体的,第一信息包括DMRS配置信息,和/或第一资源的配置信息,
DMRS配置信息,和/或第一资源的配置信息用于第一通信设备确定第一时间窗的起始位置;
DMRS配置信息,和/或第一资源的配置信息用于第一通信设备确定第一时间窗的长度。
其中,DMRS配置信息和/或第一资源的配置信息是第二通信设备为第一通信设备配置的,或者DMRS配置信息和/或第一资源的配置信息是第一通信设备根据预先定义的规则确定的,预先定义的规则可以为第一通信设备根据小区标识确定(cell identity)的,如DMRS的循环移位的index为cell-ID mod x,和/或第一资源的索引为cell-ID mod y,x和/或y为预先定义的或第二通信设备发送给第一通信设备的数值。在第一资源共享的场景下,第二通信设备可以在第一信息中携带DMRS配置信息,例如DMRS的配置信息可以为DMRS的循环移位信息(cycling shift),则第一通信设备可以在接收到第一信息之后,从该第一信息中获取到DMRS配置信息,根据该DMRS配置信息确定出第一时间窗的起始位置,由于每个通信设备的DMRS配置信息不相同,因此在多个通信设备共享第一资源的场景下,每个通信设备都可以确定属于该通信设备的第一时间窗的起始位置,从而可以避免多个通信设备在同一个时间窗的起始位置进行检测造成的相互干扰,解决了共享资源中时间窗碰撞的问题,提升系统可靠性,提高资源利用率。
在第一资源共享的场景下,第二通信设备可以在第一信息中携带第一资源的配置信息, 例如第一资源的配置信息可以是第二通信设备为第一通信设备配置的资源索引,则第一通信设备可以在接收到第一信息之后,从该第一信息中获取到第一资源的配置信息,根据该第一资源的配置信息确定出第一时间窗的起始位置,由于每个通信设备的第一资源的配置信息不相同,因此在多个通信设备共享第一资源的场景下,每个通信设备都可以确定属于该通信设备的第一时间窗的起始位置,从而可以避免多个通信设备在同一个时间窗的起始位置进行检测造成的相互干扰,解决了共享资源中时间窗碰撞的问题,提升系统可靠性,提高资源利用率。
在本申请的一些实施例中,第一时间窗的长度满足P1×Ld+B1,或者P2×Ld+B2;
其中,P1为DMRS配置信息指示的循环移位的最大索引值,或者为第二通信设备为第一通信设备配置的循环移位索引值,或者为循环移位索引的最大数量,或者为循环移位配置参数的最大数量,或者为循环移位的配置参数的数量;该循环移位的配置参数或循环移位索引用于所述第一通信设备确定循环移位值。
P2为资源配置信息指示的配置第一资源的第一通信设备的最大通信设备数量,或者第二通信设备为第一通信设备配置的资源索引,或者为第一资源中包括的通信设备的最大数量,或者为第一资源中包括的通信设备的数量,或者为第二通信设备配置的资源索引的最大数量,或者为第二通信设备配置的资源索引的数量,或者为第二通信设备配置的资源的最大数量,或者为第二通信设备配置的资源的数量。

可能的取值个数。
例如第一时间窗的长度满足P1×Ld+B1,或者P2×Ld+B2,其中,Ld为第一通信设备的搜索空间的长度,或者为预定义的搜索空间的长度,或者预定的长度。其中,第一时间窗的长度也可以称为搜索空间的持续时间段(Duration)、搜索空间的周期(periodicity)、搜索空间的重复次数(repetition number)或者物理下行控制信道(Physical Downlink Control Channel,PDCCH)的重复次数,例如物理下行信道可以包括:机器类通信物理下行 控制信道(MTC Physical Downlink Control Channel,MPDCCH)、增强物理下行控制信道(Enhanced Physical Downlink Control Channel,ePDCCH)。
B1和B2为预先规定的数值,或,B1或B2为从第二通信设备接收到的数值。例如,第一信息中可以携带B1和B2,不限定的是,还可以不在第一信息中携带B1和B2,通过其它的物理层信令或者高层信令携带B1和B2。在计算出P1×Ld之后按照B1进行偏移,可以得到第一时间窗的长度,同理,可以对P2×Ld之后按照B2进行偏移得到第一时间窗的长度。本申请实施例中,第二通信设备通过第一信息向第一通信设备指示P1和P2,从而第一通信设备可以计算出第一时间窗的长度,从而第一通信设备按照确定出的第一时间窗的长度来检测第一时间窗。
在本申请的一些实施例中,第一通信设备可以使用该第一通信设备的资源索引,或者使用该第一通信设备的DMRS循环移位索引或者循环移位的配置参数来计算出K1或者X1,或者第一通信设备可以使用该第一通信设备的资源索引,或者使用该第一通信设备的DMRS循环移位索引来计算出K2或者X2。以K1和K2的计算为例,具体的,K1满足q+i×Ld,或q+j×Ld;和/或,K2满足q+i×Ld,或q+j×Ld;
其中,q为预定义的大于或等于零的整数,或者为从第二通信设备接收到的数值;
i为第一通信设备的资源索引,
j为第一通信设备的DMRS循环移位索引,
Ld为第一通信设备的搜索空间的长度,或者为预定义的搜索空间的长度。
其中,DMRS配置信息指示了j,该j可以第二通信设备为第一通信设备配置的循环移位索引值。第一通信设备可以使用上述的j,按照预先确定的K1和K2计算方式得到第一时间窗的起始位置。第一信息还可以携带第一资源的配置信息,该第一资源的配置信息指示了i,该i可以是配置第一资源的第一通信设备的资源索引。第一通信设备可以使用上述的i,按照预先确定的K1和K2计算方式得到第一时间窗的起始位置。在多个通信设备共享第一资源的场景下,每个通信设备都可以确定属于该通信设备的第一时间窗的起始位置,从而第二通信设备对每个第一通信设备的第一时间窗的起始位置都是可配置的,可以避免多个通信设备在同一个时间窗的起始位置进行检测造成的相互干扰,解决了共享资源中时间窗碰撞的问题,提升系统可靠性,提高资源利用率。
在本申请的一些实施例中,本申请实施例中第二通信设备除了执行前述步骤201至步骤202之外,第二通信设备执行的信息处理方法还可以包括如下步骤:
第二通信设备确定第一通信设备的搜索空间在第一时间窗内的起始位置,第一时间窗包括一个或多个的搜索空间,或者第一时间窗包括一个或多个第一通信设备的搜索空间;
第二通信设备向第一通信设备发送第二信息,第二信息用于指示第一通信设备的搜索空间在第一时间窗内的起始位置。
其中,在第一时间窗内可以包括一个或多个的搜索空间。第一通信设备需要检测搜索空间在第一时间窗内的起始位置,第二通信设备可以确定第一通信设备的搜索空间在第一时间窗内的起始位置,然后第二通信设备向第一通信设备发送第二信息,从而第一通信设备可以接收到第二信息之后,根据该第二信息的指示确定第一通信设备的搜索空间在第一时间窗内的起始位置。例如第一通信设备的搜索空间在第一时间窗内的起始位置可以是第 一时间窗的起始位置,或者第一通信设备的搜索空间在第一时间窗内的起始位置可以是第一时间窗的起始位置偏移一个第二数值之后的一个位置。其中,第一时间窗的起始位置可以是根据前述方法确定的第一时间窗的起始位置,也可以按照目前已有方法确定出的第一时间窗的起始位置,此处不做限定。例如第二数值可以是根据第一通信设备的DMRS配置参数和/或第一资源的配置参数确定的,因此在多个通信设备共享第一资源的场景下,每个通信设备的搜索空间在第一时间窗内的起始位置是不相同的,避免多个通信设备之间的冲突。
211、第一通信设备从第二通信设备接收第一信息。
在本申请实施例中,第一通信设备和第二通信设备之间可以进行相互通信,例如第二通信设备发送第一信息,则第一通信设备可以从第二通信设备接收到第一信息,然后第一通信设备解析该第一信息。对于第一信息的说明,详见前述第二通信设备一侧中对第一信息的说明。
212、第一通信设备根据第一信息确定第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元,或者第一时间窗的起始位置为第一资源的结束位置之后的第K2个时间单元,第一资源为第一通信设备传输数据所使用的资源,K1和K2为正整数。
在本申请实施例中,第一通信设备从第二通信设备获取到第一信息,第一通信设备可以根据第二通信设备发送的第一信息确定出第一时间窗的起始位置。时间窗也可以称为时间段(time duration,或者time period),例如,时间窗可以是搜索空间窗,或者检测(monitoring)时间窗,或者控制信息监测(monitoring)时间窗。第一搜索时间窗是指在该时间段内(时间窗内),第二通信设备可能会发送控制信息,也就是第一通信设备在该时间段内监测第二通信设备发送的控制信息。在第一时间窗内可以包括一个或多个的搜索空间,搜索空间为时间资源和频率资源的集合。第一时间窗的起始位置是第一通信设备可以检测控制信息的起始位置,即第一通信设备可以在第一时间窗的起始位置检测控制信息或者检测搜索空间,或者,第一通信设备可以在第一时间窗的起始位置开始在搜索空间中检测控制信息。
其中,第一时间窗的起始位置可以是第一资源的起始位置之后的某个时间单元,例如第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元,K1表示时间单元的个数,例如,K1等于6,则说明第一时间窗的起始位置为第一资源的起始位置之后的第6个时间单元。
在本申请的一些实施例中,第一资源的起始位置之后的第K1个时间单元,可以指的是第一资源的起始位置之后的第一数值个时间单元后的第一时间单元,第一数值为X1,第一数值可以是第二通信设备发送给第一通信设备的或预定义的,第一通信设备确定从第一资源的起始位置之后间隔X1个时间单元后的第一时间单元是第一资源的起始位置之后的第K1个时间单元;或者第一资源的起始位置之后的X1个时间单元后的第一个有效时间单元,第一通信设备确定从第一资源的起始位置之后间隔X1个时间单元后的第一个有效时间单元是第一资源的起始位置之后的第K1个时间单元,有效时间单元可以为BL/CE子帧。
另外,第一时间窗的起始位置还可以是第一资源的结束位置之后的某个时间单元,例如第一时间窗的起始位置为第一资源的结束位置之后的第K2个时间单元,K2表示时间单元的个数,例如,K2等于4,则说明第一时间窗的起始位置为第一资源的起始位置之后的 第4个时间单元。又如,K1可以等于K2,又如,K1还可以不等于K2,具体需要根据应用场景确定K1和K2的取值。
在本申请的一些实施例中,第一资源的结束位置之后的第K2个时间单元可以指的是第一资源的结束位置之后的X2个时间单元后的第一时间单元,第一数值为X2,X2可以是第二通信设备发送给第一通信设备的或预定义的,第一通信设备确定从第一资源的结束位置之后间隔X2个时间单元后的第一时间单元是第一资源的结束位置之后的第K2个时间单元;或者第一资源的结束位置之后的X2个时间单元后的第一个有效时间单元,第一通信设备确定从第一资源的结束位置之后间隔X2个时间单元后的第一个有效时间单元是第一资源的结束位置之后的第K2个时间单元,有效时间单元可以为BL/CE子帧。
本申请实施例中,步骤212第一通信设备根据第一信息确定第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元,或者为第一资源的结束位置之后的第K2个时间单元,包括:
第一信息包括第一数值,第一通信设备确定第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元,K1是第一通信设备根据第一数值确定的;或者,
第一信息不包括第一数值,第一通信设备确定第一时间窗的起始位置为第一资源的结束位置之后的第K2个时间单元,K2是预先规定的数值,或者K2是从第二通信设备接收到的数值。
其中,第一信息指示第一时间窗的起始位置具有多种方式,例如第一信息可以携带第一数值,或者第一信息可以不携带第一数值,第二通信设备根据第一信息是否携带第一数值可以指示第一时间窗的起始位置的两种实现方式,例如第二通信设备确定第一时间窗的起始位置为第一资源的起始位置之后的位置,第二通信设备确定第一信息包括第一数值;或者,第二通信设备确定第一时间窗的起始位置为第一资源的结束位置之后的位置,第二通信设备确定第一信息不包括第一数值,则第一通信设备接收到第一信息之后,只需要检测第一信息中是否携带前述的第一数值,就可以确定第一时间窗的起始位置为上述两种实现方式中的哪一种。本申请实施例中该第一数值可以称为第一参量,该第一数值可以是根据K1确定第一数值,例如第二通信设备预先确定K1,然后根据该K1的取值来确定第一数值,例如K1和第一数值具有一一对应关系,第二通信设备可以根据该对应关系确定出第一数值。
进一步的,在本申请的一些实施例中,第一数值为K1,即第二通信设备可以确定第一数值等于K1,因此若第一信息中携带第一数值,则第一通信设备可以从第一信息中获取到第一数值,第一通信设备还可以确定K1的取值为第一信息中携带的第一数值,从而第一通信设备确定第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元。
在本申请的一些实施例中,第一数值为X1,第一数值可以是第二通信设备发送给第一通信设备的,第一通信设备确定从第一资源的起始位置之后间隔X1个时间单元后的第一时间单元是第一资源的起始位置之后的第K1个时间单元;或者第一资源的起始位置之后的X1个时间单元后的第一个有效时间单元,第一通信设备确定从第一资源的起始位置之后间隔X1个时间单元后的第一个有效时间单元是第一资源的起始位置之后的第K1个时间单元,有效时间单元可以为BL/CE子帧。
在本申请的另一些实施例中,第一数值为数值M1,M1为大于零小于或等于1的数。K1由M1和第一资源的配置参数确定。其中,第一资源的配置参数是指针对第一资源配置的参数,例如第一资源的配置参数可以是第二通信设备为第一通信设备使用第一资源而配置的参数。第一信息中可以携带数值M1,则第一通信设备从第一信息中获取到M1之后,第一通信设备可以根据预先确定的K1生成方式,使用M1和第一资源的配置参数来计算出K1,从而第一通信设备确定第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元。
进一步的,在本申请的一些实施例中,第一资源的配置参数包括如下参数中的至少一种:第一资源的周期N1、第一资源的重复次数N2、第一资源包括的时间单元个数N3。其中,N1可以是第二通信设备配置的第一资源的周期,N2是第二通信设备配置的第一资源的重复次数,N3是第二通信设备配置的第一资源包括的时间单元个数,则第一通信设备可以使用上述的N1、N2、或者N3,按照预先确定的K1生成方式得到K1。
例如K1可以满足如下三种关系中的至少一种:M1×N1+A1,或者M1×N2+A2,或者M1×N3+A3,其中,A1、A2和A3为预先规定的数值,或者,A1、A2或A3是第一通信设备从第二通信设备接收到的数值,例如A1至A3是预先确定的偏移量。A1、A2、A3还可以是第一通信设备从第二通信设备接收到的数值,例如第一信息中可以携带A1、A2、A3,不限定的是,还可以不在第一信息中携带A1、A2、A3,通过其它的物理层信令或者高层信令携带A1、A2、A3。在计算出M1×N1之后按照A1进行偏移,可以得到K1,同理,可以对M1×N2之后按照A2进行偏移得到K1,对M1×N3之后按照A3进行偏移得到K1。本申请实施例中,第二通信设备通过第一信息向第一通信设备指示M1,从而第一通信设备可以计算出K1,从而第一通信设备确定第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元。
不限定的是,基于上述计算K1的方式,还可以采用其它类似的方式,例如K1满足M1×(N1+A1),或者M1×(N2+A2),或者M1×(N3+A3),对于A1至A3的取值不做限定。
在本申请的另一些实施例中,第一数值为数值M1,M1为大于或等于零,且小于或等于1的数。X1由M1和第一资源的配置参数确定。其中,第一资源的配置参数是指针对第一资源配置的参数,例如第一资源的配置参数可以是第二通信设备为第一通信设备使用第一资源而配置的参数。第一信息中可以携带数值M1,则第一通信设备从第一信息中获取到M1之后,第一通信设备可以根据预先确定的K1或X1生成方式,使用M1和第一资源的配置参数来计算出X1,从而第一通信设备确定第一时间窗的起始位置为第一资源的起始位置之后的X1个时间单元后的第一个有效时间单元也就是第K1个时间单元。第一资源的起始位置之后间隔X1个时间单元后的第一时间单元是第一资源的起始位置之后的第K1个时间单元;或者第一资源的起始位置之后的X1个时间单元后的第一个有效时间单元,第一通信设备确定从第一资源的起始位置之后间隔X1个时间单元后的第一个有效时间单元是第一资源的起始位置之后的第K1个时间单元,有效时间单元可以为BL/CE子帧。
进一步的,在本申请的一些实施例中,第一资源的配置参数包括如下参数中的至少一种:第一资源的周期N1、第一资源的重复次数N2、第一资源包括的时间单元个数N3。其中,N1可以是第二通信设备配置的第一资源的周期,N2是第二通信设备配置的第一资源的 重复次数,N3是第二通信设备配置的第一资源包括的时间单元个数,则第一通信设备可以使用上述的N1、N2、或者N3,按照预先确定的X1生成方式得到X1。
如,X1可以满足如下三种关系中的至少一种:M1×N1+A1,或者M1×N2+A2,或者M1×N3+A3。例如,在计算出M1×N1之后按照A1进行偏移,可以得到X1,同理,可以对M1×N2之后按照A2进行偏移得到X1,对M1×N3之后按照A3进行偏移得到X1。本申请实施例中,第二通信设备通过第一信息向第一通信设备指示M1,从而第一通信设备可以计算出K1,从而第一通信设备确定第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元。
需要说明的是,M1为大于或等于零,且小于或等于1的数,从而通过上述M1×N1+A1,或者M1×N2+A2,或者M1×N3+A3等方式计算出X1,那么当第一通信设备的传输信道质量较差时,第一通信设备需要多次进行重复传输之后才有可能成功传输,目前第一通信设备还需要在PUR结束后的第4个子帧开始监测搜索空间窗,这就会导致第一通信设备在接收到第二通信设备的下行控制信息之前需要监测很长时间的搜索空间窗,极大浪费了第一通信设备的功耗。由于M1为大于零小于或等于1的数,因此在第一资源的起始位置之后的M1×N1+A1,或者M1×N2+A2,或者M1×N3+A3个时间单元后的第一个有效子帧才开始检测第一时间窗,从而不会浪费第一通信设备的功耗。
不限定的是,基于上述计算X1的方式,还可以采用其它类似的方式,例如X1满足M1×(N1+A1),或者M1×(N2+A2),或者M1×(N3+A3),对于A1至A3的取值不做限定。
本申请实施例中,步骤212第一通信设备根据第一信息确定第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元,或者为第一资源的结束位置之后的第K2个时间单元,包括:
第一信息指示第一通信设备能够提前终止传输,第一通信设备确定第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元,K1是预先规定的数值,或者K1是从第二通信设备接收到的数值;
第一信息指示第一通信设备不能够提前终止传输,第一通信设备确定第一时间窗的起始位置为第一资源的结束位置之后的第K2个时间单元,K2是预先规定的数值,或者K2是从第二通信设备接收到的数值。
其中,在提前终止传输的场景下,第二通信设备还需要指示第一通信设备是否能够提前终止传输,则本申请实施例中是否能够提前终止传输可以与第一时间窗的起始位置相关联,第二通信设备只需要向第一通信设备指示是否能够提前终止传输,则第一通信设备接收到第一信息之后,第一通信设备可以获取到第二通信设备指示的是否能够提前终止传输,第一通信设备根据是否能够提前终止传输与第一时间窗的起始位置的关联关系确定第一时间窗的起始位置为第一资源的起始位置之后的位置,或者第一时间窗的起始位置为第一资源的结束位置之后的位置。
本申请实施例中,“是否能够提前终止传输”也可以称为“是否使能提前终止传输”,使能提前终止也可以理解为第二通信设备(E-UTRAN)指示第二通信设备(E-UTRAN)可能会针对一个新的传输发送上行HARQ-ACK反馈或者是上行授权来提前终止PUSCH传输,或者是一个显式的PUSCH传输完成的确认。第二通信设备只需要指示是否使能了提前终止传输 功能,第一通信设备就可以确定出第一时间窗的起始位置,因此不需要第二通信设备再单独指示第一时间窗的起始位置,减少了信令开销,提升通信系统的性能。
在一些实施例中,第一信息指示第一通信设备能够提前终止传输,第一通信设备确定第一时间窗的起始位置为第一资源的起始位置之后间隔X1个时间单元后的第一时间单元,或者第一时间窗的起始位置为第一资源的起始位置之后的X1个时间单元后的第一个有效时间单元,有效时间单元可以为BL/CE子帧。X1可以为预定义的,或第二通信设备配置的。
第一信息指示第一通信设备不能够提前终止传输,第一通信设备确定第一时间窗的起始位置为第一资源的起始位置之后间隔X2个时间单元后的第一时间单元,或者第一时间窗的起始位置为第一资源的起始位置之后的X2个时间单元后的第一个有效时间单元,有效时间单元可以为BL/CE子帧。X2可以为预定义的,或第二通信设备配置的。
需要说明的是,K1或X1还可以是根据预先定义的方式确定的,例如根据第一资源的配置参数和第一数值确定的,第一数值为预先定义的,如第一数值为0.25或0.5。第一资源的配置参数包括如下参数中的至少一种:第一资源的周期N1、第一资源的重复次数N2、第一资源包括的时间单元个数N3。不限定的是,基于上述计算K1或X1的方式,还可以采用其它类似的方式,例如K1满足M3×N1+A1,或者M3×N2+A2,或者M3×N3+A3,对于A1至A3的取值不做限定,其中,M3是预先定义的第一数值。
在本申请的一些实施例中,步骤212第一通信设备根据第一信息确定第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元,或者为第一资源的结束位置之后的第K2个时间单元,包括:
第一信息指示第一时间窗的起始位置为第一资源的起始位置之后的位置,第一通信设备确定第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元,K1是预先规定的数值,或者K1是第二通信设备向第一通信设备发送的数值;或者,
第一信息指示第一时间窗的起始位置为第一资源的结束位置之后的位置,第一通信设备确定第一时间窗的起始位置为第一资源的结束位置之后的第K2个时间单元,K2是预先规定的数值,或者K2是第二通信设备向第一通信设备发送的数值。
其中,第一信息还可以是第二通信设备生成的用于指示第一时间窗的起始位置的专用信息,例如,第一信息指示第一时间窗的起始位置为第一资源的起始位置之后的位置;或者,第一信息指示第一时间窗的起始位置为第一资源的结束位置之后的位置。则第一通信设备可以从第二通信设备接收到该第一信息,第一通信设备按照第一信息携带的指示内容确定第一时间窗的起始位置为第一资源的起始位置之后的位置,或第一时间窗的起始位置为第一资源的结束位置之后的位置。
在一些实施例中,第一信息指示第一时间窗的起始位置为第一资源的起始位置之后的位置,第一通信设备确定第一时间窗的起始位置为第一资源的起始位置之后间隔X1个时间单元后的第一时间单元,或者第一时间窗的起始位置为第一资源的起始位置之后的X1个时间单元后的第一个有效时间单元,有效时间单元可以为BL/CE子帧。X1可以为预定义的,或第二通信设备配置的。
第一信息指示第一时间窗的起始位置为第一资源的结束位置之后的位置,第一通信设备确定第一时间窗的起始位置为第一资源的起始位置之后间隔X2个时间单元后的第一时 间单元,或者第一时间窗的起始位置为第一资源的起始位置之后的X2个时间单元后的第一个有效时间单元,有效时间单元可以为BL/CE子帧。X2可以为预定义的,或第二通信设备配置的。
针对上述第一信息的不同实现方式,举例说明如下,第一信息可以用于指示第一时间窗的起始位置位于第一资源的起始位置还是结束位置之后,或者第一信息用于是否使能提前终止传输,第一信息指示第一时间窗的起始位置位于第一资源的起始位置之后或指示使能提前终止传输,则第一时间窗位于第一资源的起始资源后的第K1个子帧。第一信息指示指示第一时间窗的起始位置位于第一资源的结束位置之后或指示去(未)使能提前终止传输,则第一时间窗的起始位置位于第一资源的结束位置后的第K2个子帧,K1和K2可以是相同的,也可以是不同的,具体可以结合应用场景来确定。第二通信设备通过上述第一信息向第一通信设备指示第一时间窗的起始位置,从而第一通信设备解析第一信息,并按照第二通信设备的指示来获取到第一时间窗的起始位置,从而可以及时检测到第一时间窗的起始位置,避免提前终止传输已经完成还没有检测到时间窗的情况。
在本申请的一些实施例中,本申请实施例中第一通信设备除了执行前述步骤211至步骤212之外,第一通信设备执行的信息处理方法还可以包括如下步骤:
第一通信设备从第二通信设备接收第二信息,第二信息用于指示第一通信设备的搜索空间在第一时间窗内的起始位置,第一时间窗包括一个或多个搜索空间;
第一通信设备根据第二信息确定第一通信设备的搜索空间在第一时间窗内的起始位置。
其中,在第一时间窗内可以包括一个或多个的搜索空间。第一通信设备需要检测搜索空间在第一时间窗内的起始位置,第二通信设备可以确定第一通信设备的搜索空间在第一时间窗内的起始位置,然后第二通信设备向第一通信设备发送第二信息,从而第一通信设备可以接收到第二信息之后,根据该第二信息的指示确定第一通信设备的搜索空间在第一时间窗内的起始位置。例如第一通信设备的搜索空间在第一时间窗内的起始位置可以是第一时间窗的起始位置,或者第一通信设备的搜索空间在第一时间窗内的起始位置可以是第一时间窗的起始位置偏移一个第二数值之后的一个位置。例如第二数值可以是根据第一通信设备的DMRS配置参数和/或第一资源的配置信息参数确定的,因此在多个通信设备共享第一资源的场景下,每个通信设备的搜索空间在第一时间窗内的起始位置是不相同的,避免多个通信设备之间的冲突。
203、第二通信设备按照第一时间窗的起始位置向第一通信设备发送控制信息。
在本申请实施例中,第二通信设备向第一通信设备指示第一时间窗的起始位置之后,第二通信设备还可以根据第一时间窗的起始位置向第一通信设备发送控制信息,由于第一通信设备已经确定了第一时间窗的起始位置,因此该第一通信设备可以按照第一时间窗的起始位置检测到第二通信设备发送的控制信息,以便第一通信设备获取到第二通信设备的控制信息。例如,控制信息用于指示第一通信设备传输的数据是否成功传输,或控制信息用于指示第一通信设备的物理上行共享信道的调度信息,或控制信息用于指示第一通信设备回退,或控制信息用于指示第一通信设备在下一个第一资源进行重传。
213、第一通信设备按照确定的第一时间窗的起始位置检测第二通信设备发送的控制信 息。
在本申请实施例中,第二通信设备向第一通信设备指示第一时间窗的起始位置之后,第二通信设备还可以按照第一时间窗的起始位置向第一通信设备发送控制信息,由于第一通信设备已经确定了第一时间窗的起始位置,因此该第一通信设备可以按照第一时间窗的起始位置检测到第二通信设备发送的控制信息,以便第一通信设备获取到第二通信设备的控制信息。例如,控制信息用于指示第一通信设备传输的数据是否成功传输,或控制信息用于指示第一通信设备的物理上行共享信道的调度信息,或控制信息用于指示第一通信设备回退,或控制信息用于指示第一通信设备在下一个第一资源进行重传。
通过前述实施例的举例说明可知,第一通信设备从第二通信设备接收第一信息,第一通信设备根据第一信息确定第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元,或者第一时间窗的起始位置为第一资源的结束位置之后的第K2个时间单元,第一资源为第一通信设备传输数据所使用的资源,K1和K2为正整数,第一通信设备按照确定的第一时间窗的起始位置检测第二通信设备发送的控制信息。本申请实施例中第二通信设备可以通过第一信息指示第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元,或者第一时间窗的起始位置为第一资源的结束位置之后的第K2个时间单元,因此第一通信设备可以按照第二通信设备的指示确定出第一时间窗的起始位置为第一资源的起始位置之后的第K1个时间单元,或者第一时间窗的起始位置为第一资源的结束位置之后的第K2个时间单元,第一时间窗的起始位置可以由第二通信设备指示给第一通信设备,该第一时间窗的起始位置可以位于第一资源的起始位置之后,从而适用于提前终止传输场景下第一通信设备对第一时间窗的检测,避免无法检测到时间窗的问题,该第一时间窗的起始位置除了可以位于第一资源的起始位置之后,也可以位于第一资源的结束位置之后,提高了第一通信设备检测第一时间窗的效率。
为便于更好的理解和实施本申请实施例的上述方案,下面举例相应的应用场景来进行具体说明。
接下来以第一通信设备为用户设备,第二通信设备为基站进行示例说明,用户设备和基站之间的交互流程如下:
一、基站确定第一信息。
二、基站向用户设备发送下行第一信息。
其中,该第一信息包括如下信息中的一种或多种:第一参量、DMRS配置信息和资源配置信息。
三、用户设备接收基站发送的第一信息。
接下来针对第一信息为第一参量、DMRS配置信息和资源配置信息分别进行示例说明。
当该第一信息为第一参量时:
该第一参量用于指示用户设备确定搜索空间窗的起始位置,例如该第一参量还可以用于确定搜索空间窗内的搜索空间的起始位置,搜索空间窗内的搜索空间的起始位置可以简称为“搜索空间的起始位置”。
如图3所示,为本申请实施例中提供的搜索空间窗的起始位置的示意图。示例性的,该第一参量可以为第一数值x,该数值x为大于或等1的正整数,用户设备根据第一参量 确定搜索空间窗的起始位置为第一资源(如PUR)的第一位置(如第一个子帧或最后一个子帧)后的第x个子帧。需要说明的是,子帧可以理解为有效子帧或绝对子帧。同样搜索空间窗可以理解为检测搜索空间的时间段,即在该时间段内需要监测第一搜索空间。搜索空间窗只是一种示例性的命名,也可以命名为诸如搜索空间时间长度,搜索空间时间段等其他名字,此处不做具体限定。
示例性的,该第一参量也可以为第二数值y,y即为前述的M1,y为大于或等于0且小于或等于1的数,用户设备根据第二数值y确定搜索空间窗的起始位置。第一参数可以为第一资源的周期、重复次数或包含的绝对子帧数。例如第一参数为重复次数N,那么搜索空间的起始位置为第一资源第一位置后的第N*y个子帧。

接下来举例说明第一信息为DMRS配置信息和或资源配置信息时的搜索空间窗的确定方式。
示例性的,搜索空间的长度或搜索空间窗的长度是根据第一资源中的(最大)用户设备数确定的,或者也可以称为搜索空间的长度或搜索空间窗的长度是与第一资源中的(最大)用户设备数是相互关联的。例如,搜索空间的长度或者搜索空间窗的长度L为L=N*Ld,其中Ld为第一长度,例如第一长度为第一类型(如用户设备特定PUR)的搜索空间的长度,或者第一长度为预定义的时间窗长度。可选的,第一资源中的(最大)用户设备数可以为预定义的,如N=8,第一资源中的用户设备数也可以为基站配置的,如资源配置信息中包括该数量信息;第一资源中的(最大)用户设备数也可以理解为共享第一资源的(最大)用户设备数,或者可以理解为DMRS循环移位的(最大)数量。
示例性的,搜索空间或搜索空间窗的起始位置是根据第一信息确定的。例如搜索空间或搜索空间时间窗的起始位置是根据DMRS的第一配置确定的,例如第一配置为循环移位,如DMRS循环移位对应的索引(index)i。例如第一配置为正交覆盖码(orthogonal cover code,OCC),如OCC对应的index i。
例如,第一资源的搜索空间或搜索空间窗可以为L=N*Ld,其中Ld为第一长度,N为第一资源中的用户设备总数,则该用户设备的搜索时间窗或搜索空间的位置为索引为i的搜索空间的位置,或者起始位置为(i-1)*Ld。可选的,该位置是相对于第一资源的起始位置或结束位置所确定的。

可选的,搜索空间或者搜索空间窗的位置是相对于第一资源的起始位置或结束位置所确定的,用户设备还接收第四信息,第四信息用于指示用户设备是否使能数据提前终止或指示用户设备搜索空间的起始位置是相对于PUR开始的位置,还是相对于PUR结束的位置。
示例性的,用户设备搜索空间的起始位置或搜索空间窗的起始位置是可配的,且根据第一信息确定的,可选的起始位置为q+i*Ld,例如q=4,其中i是根据用户设备资源(配置给该用户设备的PUR资源)或者DMRS配置(如DMRS的循环移位索引)所确定的,例如i为用户设备资源索引,或DMRS循环移位索引。
示例性的,用户设备的搜索空间所使用的频率资源是根据第一信息确定的。例如系统带宽包括K个频率位置,用户设备配置的资源索引为i或者DMRS的循环移位索引为i,则该用户设备的搜索空间所使用的频率资源的索引为i。

本申请实施例方案也可用于其他通信系统与其他系统的兼容中,如NR系统与增强型的机器类通信(enhanced machine type communication,eMTC)系统、进一步增强型的机器类通信(Further eMTC,FeMTC)系统的兼容等。
本申请实施例中,通过是否配置搜索空间窗的起始位置来隐式的指示PUR搜索空间的起始位置是位于PUR资源的开始位置还是结束结束,从而使能了提前终止传输功能,减少了信令开销,提升系统性能。通过将搜索空间的起始位置与DMRS或PUR的资源配置相结合,解决共享资源中搜索空间碰撞的问题,提升系统可靠性,提高资源利用率。
实施例一:
在目前的预配置传输中,支持多个用户共享同一个传输资源。在传输信号过程中,用户的信道状态是不断变化的,因此传输重复次数也会随着不断变化,但是共享的预配置资源的大小是固定的,因此当用户传输重复次数过多时,该预配置资源无法满足该用户的传输需求。而当信道变好传输重复次数变少时,如果仍然和重复次数较多的用户共享一个预配置资源时,该用户仍然会占用该共享资源,但是实际使用的资源却很少,会造成较为严重的资源浪费。
本申请实施例提供如下方案:
第二通信设备向第一通信设备发送第一指示信息,所述第一指示信息用于指示第一次数和/或第二次数,第一次数小于第二次数。
在本申请的一些实施例中,第一指示信息为第一次数和/或第二次数。
在本申请中的另外一些实施例中,第一指示信息指示第一参数和/或第二参数,第二通信设备根据第一参数和第一通信设备的信号传输的第一重复次数确定第一次数,和/或第二通信设备根据第二参数和第一通信设备的信号传输的第一重复次数确定第二次数。例如根据第一参数和第一重复次数的乘积确定第一次数,根据第二参数和第一重复次数确定第二次数。可选的,第一重复次数为第一次配置PUR的重复次数,或者,第一重复次数还可以为第一资源长度(包含的子帧个数,或者包含的有效子帧个数,或者包含的BL/CE子帧个数),或者,第一重复次数还可以为第一资源的最大长度(包含的子帧个数,或者包含的 有效子帧个数,或者包含的BL/CE子帧个数)。
其中,第一通信设备的信号传输的重复次数大于或等于第一次数,且第一通信设备的信号传输的重复次数小于或等于第二次数,所述第二通信设备通过第一资源从第一通信设备接收信号;或者,
第一通信设备的信号传输的重复次数大于或等于第一次数,所述第二通信设备通过第一资源从第一通信设备接收信号;或者
第一通信设备的信号传输的重复传输次数小于或等于第二次数,所述第二通信设备通过第一资源从第一通信设备接收信号。
在本申请实施例中,第一通信设备接收第二通信设备发送的第一指示信息,所述第一指示信息用于指示第一次数和/或第二次数,第一次数小于第二次数;

第一通信设备的信号传输的重复次数大于或等于第一次数,所述第一通信设备确定通过第一资源发送信号;或者
第一通信设备的信号传输的重复传输次数小于或等于第二次数,所述第一通信设备确定通过第一资源发送信号。
所述第一通信设备使用第一资源向第二通信设备发送信号。
其中,第一次数也可以称为第一长度,第二次数也可以称为第二长度。信号可以为物理上行共享信道,上行数据,上行探测参考信号,上行解调参考信号中的一个或多个。
在本申请的一些实施例中,第一通信设备的重复传输次数大于第二次数,所述第一通信设备发起随机接入,或所述第一通信设备进行数据早传(Early data transmission)、或者所述第一通信设备释放第一资源。
在本申请的一些实施例中,第二通信设备还向第一通信设备发送第二指示信息,第一通信设备接收第二指示信息,第一通信设备的重复传输次数大于第二次数,第二指示信息指示所述第一通信设备发起随机接入,或第二指示信息指示所述第一通信设备进行数据早传(Early data transmission)、或者第二指示信息指示所述第一通信设备释放第一资源。
在本申请的一些实施例中,第二通信设备还向第一通信设备发送第三指示信息,第一通信设备接收第三指示信息,第一通信设备的重复传输次数小于第一次数,所述第三指示信息指示所述第一通信设备使用第三资源传输信号,第一资源与第三资源是不同的资源。
在本申请的一些实施例中,第一通信设备的重复传输次数小于第一次数,所述第一通信设备使用第三资源传输信号,第一资源与第三资源是不同的资源。
示例性的,第一资源和第二资源为PUR资源。
对于周期性业务,为了降低资源开销,降低数据传输时延和节能,可在预先定义好的资源上传输业务,也就是不需要DCI动态调度,终端设备可以在预先配置的资源上传输上行信息,其中,上行信息可以包括数据、控制信息和参考信号中的一种或多种,对于上行信息的具体形式,此处不做具体限定。另外,需要进行说明的是,预先配置的上行资源(preconfigured uplink resource,PUR)仅是一种示例性命名,其实质是网络设备通过 配置第一资源,终端设备可以在不需要网络设备动态调度或下行控制信息调度的情况下在第一资源上进行上行信息的传输,该资源也可以命名为其他名称,如配置授权资源,应理解,若该配置授权资源也可以实现本申请实施例中的第一资源所实现的功能,也可以将配置授权资源理解为本申请实施例中的第一资源。为了描述方便,本申请实施例中将第一资源统一称为预配置资源。
举例说明如下,基站发送第一指示信息,所述第一指示信息用于指示第一次数(长度)和或第二次数(长度),第一长度小于第二长度。
示例性的,当用户重复次数大于第一长度和或小于第二长度时,使用第一资源传输信号。
示例性的,当用户的传输重复次数大于第二长度时,用户发起随机接入或数据早传(Early data transmission),和或释放第一资源。例如,当用户的传输重复次数大于第二长度时,用户使用第二资源传输信号,第一资源与第二资源不同,且均为预配置资源。
示例性的,当重复次数小于第一长度时,用户使用第三资源传输信号,第一资源与第三资源是不同的。
当用户重复次数较大时,不再适合在当前共享资源中传输信号,因此发送EDT或RACH进行回退,或者使用资源较长的资源来传输信号,可以避免用户无法传输信号的问题,提升传输成功概率。当重复次数较少时,切换传输资源,可以将重复次数都较小的用户分配到相同的资源中,充分利用资源,避免浪费。
实施例二:
目前,通信系统可以支持用户的回退,但是如何指示用户回退还没有解决方案,本申请实施例还可以解决了如何指示用户回退的问题。
本申请实施例提供如下方案:

本申请实施例中,通过设计信令来指示用户的回退,并且指示其会退到EDT还是RACH,增加指示的灵活性,另外通过区分字段可以有效的将反馈ACK/调度重传的DCI和指示回退的DCI区分开,提升指示的准确性和增加了DCI指示的灵活性。
实施例三:
目前的通信系统支持调度重传,但是调度重传中如何指示使用的传输资源还是一个未解决的问题。

示例性的,资源分配字段在第二频率范围内指示频率资源,第二频率范围为PUR资源
调度重传过程中PUR资源是空闲的,此时可以再次分配给用户调度重传使用,因此可以通过资源分配字段来指示是否使用PUR资源,以及通过一个字段来指示分配的资源是在一定的带宽内还是在PUR资源范围内,通过重用PUR资源,提升资源利用率,DCI通过引入指示字段提升了灵活性。
实施例四:
当多个用户共享PUR资源时,解调参考信号(demodulation reference signal,DMRS)需要彼此正交或者彼此相关性要较小。但是对于分配两个子载波的场景,还没有相关技术解决DMRS正交的问题。
