为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
参见图1,图1为本公开实施例提供的网络结构示意图,如图1所示,
包括一个或者多个UE11和基站12,其中,附图中以一个UE11进行举例示意。其中,UE11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant,简称PDA)、移动上网装置(Mobile Internet Device,MID)或可穿戴式设备(Wearable Device)等终端侧设备,需要说明的是,在本公开实施例中并不限定UE11的具体类型。UE11可以与基站12建立通信,其中,附图中的网络可以表示UE11与基站12无线建立通信,基站12可以是演进型基站(eNB,evolved Node B)、5G基站或者其他基站,需要说明的是,在本公开实施例中并不限定基站12的具体类型。
基于图1所示的网络结构,本公开实施例提供一种传输资源确认方法,如图2所示,包括以下步骤:
201、UE接收基站发送的下行控制信息,所述下行控制信息包括资源信息,所述资源信息用于表示传输时间间隔(Transmission Time Interval,TTI)的控制区域内的资源分配情况;
202、UE根据所述资源信息确定所述控制区域内用于传输数据的资源。
上述传输时间间隔可以是上述下行控制信息对应的时间时隔,例如:UE可以是在该传输时间间隔中的特定资源位置检测下行控制信道,以获取上述下行控制信息。另外,上述传输时间间隔内可以包括控制区域,其中,上述控制区域可以理解为资源可用于控制信道传输的区域,即该区域中资源可以用于控制信道传输,但本公开实施例中,将该区域中没有被控制信道占用的资源确定为可用于传输数据的资源,从而可以避免控制区域内的资源没有被使用,而造成资源浪费问题,以提高资源的利用率。另外,上述传输时间间隔可以是长度小于或者等于1ms的传输时间间隔。
另外,上述资源信息用于表示传输时间间隔的控制区域内的资源分配情况可以理解为,上述资源信息表示该控制区域内控制信道占用的资源情况,或者可以理解为,上述资源信息表示该控制区域内用于传输数据的资源分配情况,即通过上述资源信息可以确定上述控制区域内的资源分配情况。
上述UE根据所述资源信息确定所述控制区域内用于传输数据的资源可以理解为,UE根据上述资源信息确定没有被控制信道占用的资源作为用于传
输数据的资源。例如:上述控制区域包括10个控制单元,其中,控制信道占用其中5个控制单元,则可以确定另外5个控制单元可以作为用于传输数据的资源。另外,上述步骤202确定的用于传输数据的资源可以理解为确定的可用于传输数据的资源,即表示UE可以使用这些资源传输数据。UE确定上述用于传输数据的资源后,就可以使用其进行数据传输,例如:可以使用上述用于传输数据的资源中的全部或者部分资源进行数据传输。
通过上述步骤就可以实现确定控制区域内的资源为用于传输数据的资源,这样可以避免控制区域内的资源没有被使用,而造成资源浪费问题,从而提高资源的利用率。
可选的,所述资源信息用于表示传输时间间隔的控制区域内的控制信道占用的资源;
所述UE根据所述资源信息确定所述控制区域内用于传输数据的资源,包括:
所述UE根据所述资源信息确定所述控制区域内控制信道占用的资源,并将所述控制区域内没有被控制信道占用的资源作为用于传输数据的资源。
该实施方式中,可以实现通过上述资源信息表示控制信道占用的资源,当然,这里控制信道占用的资源可以其他终端的控制信道占用的资源,则上述UE自己的控制信道占用的资源,UE知道的,例如:UE可以通过无线网络临时标识(RNTI,Radio Network Temporary Identity)确定自己的信道控制资源(USS),或者在其他约定的位置确定自己的控制信道资源,例如从CCE0开始盲检(CSS),从而UE可以确定上述控制区域内没有被控制信道占用的资源。或者上述资源信息可以表示上述控制区域内被控制信道占用的资源,这里被占用包括其他终端和上述UE自己占用的资源。UE接收到该资源信息后,就可以根据该资源信息确定所述控制区域内控制信道占用的资源,并将所述控制区域内没有被控制信道占用的资源作为用于传输数据的资源。
可选的,该实施方式中,上述资源信息包括如下一项或者多项:
其他终端的控制信道在所述控制区域内所占的起始控制单元编号和所述其他终端的聚合等级信息,其中,所述其他终端为除所述UE之外的一个或者多个终端;
其他终端的控制信道在所述控制区域内所占的结尾控制单元编号和所述其他终端的聚合等级信息,其中,所述其他终端为除所述UE之外的一个或者多个终端;
其他终端的控制信道在所述控制区域内所占的控制单元编号,其中,所述其他终端为除所述UE之外的一个或者多个终端;
所述控制区域内被控制信道占用的所有控制单元的信息;
所述控制区域内各控制单元的被控制信道占用的情况信息;
所述控制区域内被控制信道占用的控制单元的最后一个控制单元编号;
所述控制区域内被控制信道占用的控制单元所属的控制单元组的编号。
其中,当上述资源信息包括其他终端的控制信道在所述控制区域内所占的起始控制单元编号和所述其他终端的聚合等级信息时,那么上述UE就可以根据起始控制单元编号和聚合等级信息确定其他终端的控制信道占用的资源,以及结合自己的控制信道占用的资源,确定所述控制区域内没有被控制信道占用的资源,并将其作为用于传输数据的资源。
例如:以控制单元为控制信道单元(control channel element,CCE)进行举例,控制区域内可用于控制信道传输的CCE个数为N,逻辑编号为0,1,2,...,N-1。假设在该传输时间间隔内调度了两个终端,分别为UE1和UE2,且UE1的聚合等级为1,UE2的聚合等级为2。基站在调度UE1的下行控制信息(Downlink Control Information,DCI)中包含了UE2的控制信道占用CCE的起始编号以及聚合等级,例如UE2的物理下行控制信道(Physical Downlink Control Channel,PDCCH)占用的CCE起始编号为N-3或者N-4,其聚合等级为2。基站在调度UE2的DCI中包含了UE1的控制信道占用的CCE起始编号以及聚合等级,例如UE1的PDCCH占用的CCE起始编号为0,其聚合等级为1。UE1就可以根据DCI中的资源分配信息以及控制区域中UE2的控制信道的聚合等级以及占据资源的起始CCE编号,确定在控制区域中用于传输数据的资源,同理,UE2也可以确定控制区域中用于传输数据的资源。例如:如图3a或者图3b所示。
例如:以控制单元为控制单元(control unit,CU)进行举例,假设在控制区域内可用于控制信道传输的CU个数为N,逻辑编号为0,1,2,...,N-1。
假设在该传输时间间隔内调度了两个终端,分别为UE1和UE2,且UE1的控制信道占用1个CU,UE2的控制信道占用2个CU。基站在调度UE1的DCI中包含了UE2的控制信道占用CU的起始编号以及个数,例如UE2的控制信道占用的CU起始编号为N-3或者N-4,其占用CU的个数为2。基站在调度UE2的DCI中包含了UE1的控制信道占用的CU起始编号以及其占用CU的个数,例如UE1的PDCCH占用的CU起始编号为0,其占用CU的个数为1。例如UE1的PDCCH占用的CU起始编号为0,其聚合等级为1。UE1就可以根据DCI中的资源分配信息以及控制区域中UE2的控制信道的聚合等级以及占据资源的起始CU编号,确定在控制区域中用于传输数据的资源,同理,UE2也可以确定控制区域中用于传输数据的资源。例如:如图4a或者图4b所示。
其中,当上述资源信息包括其他终端的控制信道在所述控制区域内所占的结尾控制单元编号和所述其他终端的聚合等级信息,UE同样可以结合自己的控制信道占用的资源,确定所述控制区域内没有被控制信道占用的资源,并将其作为用于传输数据的资源,具体实现可以参考上面介绍的起始控制单元编号的实现方式,此处不作重复说明。
其中,当上述资源信息包括其他终端的控制信道在所述控制区域内所占的控制单元编号,UE同样可以结合自己的控制信道占用的资源,确定所述控制区域内没有被控制信道占用的资源,并将其作为用于传输数据的资源。
例如:以控制单元为CCE进行举例,假设在控制区域内可用于控制信道传输的CCE个数为N,逻辑编号为0,1,2,...,N-1。假设在该传输时间间隔内存在两个终端的控制信道,两个终端分别为UE1和UE2,且UE1的聚合等级为1,UE2的聚合等级为2。例如,假设N=6,调度UE1的DCI中包含用于指示UE2的控制信道在控制区域中占用的CCE编号,调度UE2的DCI中包含用于指示UE1的控制信道在控制区域中占用的CCE编号。假设UE1的控制信道占用的CCE为CCE0,UE2的控制信道占用的CCE为CCE2何CCE3。则UE1的DCI中指示UE2的控制信道占用CCE的信息bit为00100,UE2的DCI中指示UE1的控制信道占用CCE的信息bit为00000。这样可以实现UE1和UE2通过该
信息域以及DCI中的资源分配域,获得控制区域中用于数据传输的资源位置。例如:如图5所示。
例如:以控制单元为CU进行举例,假设在控制区域内可用于控制信道传输的控制单元个数为N,逻辑编号为0,1,2,...,N-1。假设在该传输时间间隔内存在两个终端的控制信道,两个终端分别为UE1和UE2,且UE1的控制信道占用的控制单元个数为1,UE2的控制信道占用的控制单元个数为2。例如,假设N=6,调度UE1的下行控制信息中包含用于指示UE2的控制信道在控制区域中占用的下行控制单元编号,调度UE2的下行控制信息中包含用于指示UE1的控制信道在控制区域中占用的控制单元编号。假设UE1的控制信道占用的控制单元为CU0,UE2的控制信道占用的控制单元为CU2和CU3。则UE1的下行控制信息中指示UE2的控制信道占用CU的信息bit为00100,UE2的下行控制信息中指示UE1的控制信道占用CU的信息bit为00000。UE1和UE2通过该信息域以及下行控制信息中的资源分配域,获得控制区域中用于数据传输的资源位置。例如:如图6所示。
其中,当上述资源信息包括上述控制区域内被控制信道占用的所有控制单元的信息,那么,上述UE就可以直接确定上述控制区域内用于数据传输的资源。即将除被控制信道占用的所有控制单元的信息之外的资源确定为上述控制区域内用于数据传输的资源。例如:上述资源信息包括被控制信道占用的所有控制单元的编号或者位置信息。
其中,上述控制区域内各控制单元的被控制信道占用的情况信息可以理解为,各控制单元是否被控制信道占用的信息,即通过该信息可以确定哪些控制单元被控制信道占用,哪些没有被控制信道占用。例如:以控制单元为CCE进行举例,假设在控制区域内可用于控制信道传输的CCE个数为10,逻辑编号为0,1,2,...,9。假设在该传输时间间隔内存在两个终端的控制信道,两个终端分别为UE1和UE2,且UE1的聚合等级为1,UE2的聚合等级为2。基站在调度UE1和调度UE2的DCI1和DCI2中,均包含指示控制区域中用于传输控制信道的指示信息,1表示对应CCE用于控制信道传输,0表示对应CCE未被控制信道占用。例如,控制区域的10个CCE,其中CCE0
用于UE1的控制信道,CCE2和CCE3用于UE2的控制信道,则在调度UE1和调度UE2的DCI1和DCI2中分别包含位置(bitmap)信息域(1110000000),UE1和UE2通过该bitmap信息域以及DCI中的资源分配域,获得控制区域内可用于数据传输的资源位置。例如:如图3a和3b所示。
例如:以控制单元为CU进行举例,假设在控制区域内可用于控制信道传输的CU个数为10,逻辑编号为0,1,2,...,9。假设在该传输时间间隔内存在两个终端的控制信道,两个终端分别为UE1和UE2。基站在调度UE1和调度UE2的下行控制信息1和下行控制信息2中,均包含指示控制区域中用于传输控制信道的指示信息,1表示对应控制单元用于控制信道传输,0表示对应控制单元未被控制信道占用。例如,控制区域的10个控制单元,其中控制单元0用于UE1的控制信道,控制单元2和控制单元3用于UE2的控制信道,则在调度UE1和调度UE2的下行控制信息1和下行控制信息2中分别包含bitmap信息域(1110000000),UE1和UE2通过该bitmap信息域以及下行控制信息中的资源分配域,获得控制区域内可用于数据传输的资源位置。例如:如图4a和4b所示。
其中,当上述信道信息包括上述控制区域内被控制信道占用的控制单元的最后一个控制单元编号时,UE可以将该编号之后的资源作为用于数据传输的资源,例如:基站在调度时在上述控制区域内控制信道资源只能连续分配,从而可以确定上述编号之前的资源是控制信道占用的资源,之后的资源可以确定为用于数据传输的资源。其中,上述控制区域内被控制信道占用的控制单元的最后一个控制单元编号可以理解为,上述控制区域内所有接收控制信令的终端的控制信道占用的控制单元的最后一个控制单元编号。
例如:以控制单元为CCE进行举例,假设在控制区域内可用于控制信道传输的CCE个数为N,逻辑编号为0,1,2,...,N-1。假设在该传输时间间隔的控制区域内存在三个终端的控制信道,三个终端分别为UE1、UE2和UE3,且UE1的聚合等级为1,UE2的聚合等级为2,UE3的聚合等级为2。以UE2为例,假设三个终端的控制信道占用了5个CCE,且该5个CCE只能从最低编号开始记数。由于UE2通过盲检可以获知自身控制信道的起始CCE编号以及控制信道的聚合等级,因此通过DCI中携带的在该传输时间间隔的控制
区域中占用的最后一个CCE编号,就可以获得在控制区域中用于数据传输的资源位置。示意图如图7a和图7b所示。在调度UE2的DCI中,通知控制区域中用于控制信道传输的总的CCE个数,如图7a和图7b所示,CCE个数为6。UE2通过盲检获知自己使用的CCE为CCE2和CCE3,则根据控制信道的映射规则以及被控制信道占用的CCE总数,可以获知CCE0、CCE1、CCE4和CCE5均不能用于数据传输。但由于UE1的聚合等级为1,即如图7a和图7b所示,CCE1是可以用于数据传输的,当上述信道信息包括控制区域内被控制信道占用的控制单元的最后一个控制单元编号,以及其他终端的聚合等级信息时,UE1、UE2和UE3就可以确定UE1的控制信道只占用了CCE0,从而确定CCE1可用于数据传输。即可以在调度UE2和UE3的DCI中携带UE1的聚合等级信息,从而可以进一步提高资源利用率。
例如:以控制单元为CU进行举例,假设在控制区域内可用于控制信道传输的CU个数为N,逻辑编号为0,1,2,...,N-1。假设在该传输时间间隔的控制区域内存在三个终端的控制信道,三个终端分别为UE1、UE2和UE3,且UE1的控制信道占用的控制单元个数为1,UE2的控制信道占用的控制单元个数为2,UE3的控制信道占用的CU个数为2。以UE2为例,假设三个终端的控制信道占用了5个CU,且该5个CU只能从最低编号开始记数。由于UE2通过检测可以获知自身控制信道的起始控制单元编号以及控制信道占用的控制单元数目,因此通过下行控制信息中携带的在该TTI的控制区域中控制信道占用的最后一个CU编号,就可以获得在控制区域中用于数据传输的资源位置。示意图如图8a和图8b所示。在调度UE2的下行控制信息中,通知控制区域中用于控制信道传输的总的控制单元个数,如图8a和图8b所示,控制单元个数为6。UE2通过检测获知自己使用的CU为CU2和CU3,则根据控制信道的映射规则以及被控制信道占用的CU总数,可以获知CU0、CU1、CU4和CU5均不能用于数据传输。进一步的,可以在调度UE2的DCI中携带UE1的控制信道占用的控制单元个数,从而可以确定CU1可用于数据传输,从而可以进一步提高资源利用率。
其中,在上述资源信息包括控制区域内被控制信道占用的控制单元所属的控制单元组的编号,UE可以确定哪些控制单元组存在控制信道占用的资
源,从而可以将不包括控制信道占用资源的控制单元组确定为用户数据传输的资源。或者可以将存在控制信道占用的资源中没有被控制信道占用的资源确定为用于传输数据的资源。另外,每个控制单元组可以包括一个或者多个连续的控制单元。
例如:以控制单元为CCE举例,假设在控制区域内可用于控制信道传输的CCE个数为N,逻辑编号为0,1,2,...,N-1。假设在该传输时间间隔的控制区域内存在两个终端的控制信道,两个终端分别为UE1、UE2,且UE1的聚合等级为1,UE2的聚合等级为2。以UE2为例,假设两个终端的控制信道占用了2个CCE组(CCE group),每个CCE group内包含3个CCE。示意图如图9a和9b所示。在调度UE2的DCI中,通知控制区域中用于控制信道传输的CCE group编号,当然,一些场景中DCI指示控制信道传输的CCE group个数也是可以实现,例如:当在传输时间间隔内只调度了UE2的控制信道传输,即控制信道传输的CCE group个数为1,从而UE2可以确定其他CCE group可用于数据传输。UE2通过盲检获知自己使用的CCE为CCE group1,则根据控制信道的映射规则以及被控制信道占用的CCE group编号或者个数,可以获知CCE0、CCE1、CCE2和CCE5均不能用于数据传输。
例如:以控制单元为CU举例,假设在控制区域内可用于控制信道传输的CU个数为N,逻辑编号为0,1,2,...,N-1。假设在该传输时间间隔的控制区域内存在两个终端的控制信道,两个终端分别为UE1、UE2,且UE1的控制信道占用的CU个数为1,UE2的控制信道占用的CU个数为2。以UE2为例,假设两个终端的控制信道占用了2个CU group,每个CU group内包含3个控制单元。示意图如图10a和10b所示。在调度UE2的下行控制信息中,通知控制区域中用于控制信道传输的控制单元group编号或者个数。UE2通过检测获知自己使用的控制单元group为控制单元group1,则根据控制信道的映射规则以及被控制信道占用的控制单元group编号或者个数,可以获知CU0、CU1、CU2和CU5均不能用于数据传输。
可选的,上述所述资源信息用于表示传输时间间隔的控制区域内的用于传输数据的资源。
该实施方式中,可以实现通过上述资源信息直接表示用于传输数据的资
源,从而UE可以通过该资源信息直接确定用于传输数据的资源。另外,上述资源信息还可以表示上述UE在传输时间间隔的控制区域内的用于传输数据的资源,即基站为该UE分配控制区域内用户传输数据的资源。另外,上述资源信息可以是通过位图或者指示信息实现指示上述控制区域内的用于传输数据的资源。
可选的,该实施方式中,上述资源信息包括:
所述控制区域内实际用于传输数据的控制单元的信息。
该实施方式中,上述控制单元的信息可以是每个控制单元的编号。或者用于传输数据的控制单元为连续的控制单元,则上述信息可以是用于传输数据的控制单元的起始单元和结尾单元的编号。或者上述信息还可以是用于传输数据的控制单元中起始控制单元的编号,即从该编号开始到传输时间间隔结束所有控制单元都是用于传输数据的控制单元。
例如:以控制单元为CCE进行举例,假设在控制区域内可用于控制信道传输的CCE个数为N+2,逻辑编号为0,1,2,...,N+1。假设在该传输时间间隔内调度了两个终端,分别为UE1和UE2,且UE1的聚合等级为1,UE2的聚合等级为2。基站侧在调度UE1的DCI中包含了控制区域中UE1的数据传输可以使用的CCE信息,例如CCE1和CCE2可以用于UE1的数据传输。基站侧在调度UE2的DCI中包含了控制区域中UE2的数据传输可以使用的CCE信息,例如CCE N+1可以用于UE2的数据传输。UE根据DCI中的资源分配信息以及控制区域中自身可以使用的控制单元信息,获知在传输时间间隔(短TTI,即长度小于1ms的TTI)内数据传输可以使用的资源。例如:如图11所示。
例如:以控制单元为CCE进行举例,假设在控制区域内可用于控制信道传输的CCE个数为N+2,逻辑编号为0,1,2,...,N+1。假设在该传输时间间隔内调度了两个终端,分别为UE1和UE2,且UE1的聚合等级为1,UE2的聚合等级为2。基站侧在调度UE1的DCI中包含了控制区域中UE1的数据传输可以使用的CCE信息,例如CCE1和CCE2可以用于UE1的数据传输。基站侧在调度UE2的DCI中包含了控制区域中UE2的数据传输可以使用的CCE信息,例如CCE N+1可以用于UE2的数据传输。UE根据DCI中的资
源分配信息以及控制区域中自身可以使用的控制单元信息,获知在传输时间间隔(短TTI,即长度小于1ms的TTI)内数据传输可以使用的资源。例如:如图12所示。
可选的,上述方法还可以包括:
所述UE根据所述下行控制信息确定数据传输资源,其中,所述数据传输资源包括所述控制区域内用于传输数据的资源,或者所述数据传输资源包括所述控制区域内用于传输数据的资源和所述传输时间间隔的数据区域内的资源。
该实施方式中,可以实现UE根据上述下行控制信息确定数据传输资源,且该数据传输资源可以包括控制区域内用于传输数据的资源和/或所述传输时间间隔的数据区域内的资源。例如:如图3至11所示的数据传输资源。
可选的,上述下行控制信息还包括下行数据信道的调度信息。
该实施方式中,可以实现下行控制信息中包括下行数据信道的调度信息,从而UE可以根据下行控制信息确定控制区域内用户传输数据的资源,以及数据区域内的资源。
可选的,若所述资源信息为无效值时,则表示所述控制区域内所有资源均不能用于传输数据。
该实施方式中,可以实现通过上述资源信息为无效值,例如:资源信息的信息域为全1,则表示控制区域内的所有资源均不能用于数据的传输1。例如:假设所述DCI中需要携带N个其他终端在所述传输时间间隔的控制区域所占的资源信息,则当实际调度终端数目大于N时,则基站将该信息域设置为无效值,以表示所述控制区域内所有资源均不能用于传输数据。
需要说明的是,本公开实施例中提供的上述多种可选的实施方式,可以相互结合实现,也可以单独实现,对此本公开实施例不作限定。
本公开实施例,UE接收基站发送的下行控制信息,所述下行控制信息包括资源信息,所述资源信息用于表示传输时间间隔的控制区域内的资源分配情况;所述UE根据所述资源信息确定所述控制区域内用于传输数据的资源。这样可以实现确定控制区域内的资源为用于传输数据的资源,这样可以避免控制区域内的资源没有被使用,而造成资源浪费问题,从而本公开实施例可
以进一步提高资源的利用率。
