Description
本申请涉及通信领域,更具体地,涉及一种信号传输的方法和装置。
***未来的第五代(5th Generation,5G)通信中采用比长期演进(Long Term Evolution,LTE)更高的载波频率,如38GHz、72GHz等6GHz以上的载波频率,从而实现更大带宽、更高传输速率的无线通信。由于载波频率较高,无线信号在空间传播过程中经历更加严重的衰落,甚至接收端可能难以检测出该无线信号。为此,5G通信***中将采用波束赋形(beamforming)技术来获得良好方向性的波束。波束赋形技术用于将传输信号的能力限制在某个波束方向内,从而增加信号发送和接收的效率。
由于采用波束赋形技术的波束覆盖范围较窄,且网络设备不知道终端设备的具***置,因此网络设备可以发送广播信息(例如,寻呼(paging)消息)进行波束扫描,才能覆盖未知终端设备的位置。为了降低寻呼消息传输过程中的波束扫描的开销,当有paging消息来的时候,网络设备可以预先发一个寻呼指示消息(paging indication),终端设备接收到网络设备广播的寻呼指示消息之后反馈随机接入前导(preamble)以上报信号质量较好的波束,网络设备再根据终端设备上报的波束进行下发paging消息,这样网络设备可以避免向终端设备接收较差的方向发送paging消息,从而减少了波束扫描的开销。
终端设备可以在接收到寻呼指示消息之后反馈随机接入前导,由于随机接入前导关联的信息较多,造成开销较多。
发明内容
本申请提供一种信号传输的方法和装置,能够减少随机接入前导的开销。
一方面,公开了一种信号传输的方法,包括:
网络设备向终端设备发送的寻呼指示,所述寻呼指示携带多个寻呼分组信息;所述终端设备根据所述多个寻呼分组中被寻呼的寻呼分组与随机接入前导的关联关系,向所述网络设备发送所述终端设备所在的寻呼分组关联的随机接入前导;进一步的,网络设备可以根据接收到的所述终端设备所在的寻呼分组关联的随机接入前导,向所述终端设备发送寻呼消息。
所述多个寻呼分组中被寻呼的寻呼分组可以是一个或多个,本申请多个的含义是两个或两个以上。上述方案中,网络设备可以根据所述关联关系确定所述终端设备所在的寻呼分组关联的随机接入前导,并发送所述随机接入前导,由于仅有被寻呼的寻呼分组与随机接入前导存在关联关系,从而节省了前导的开销。
结合上述方案,关联被寻呼的寻呼分组的随机接入前导的数量大于或等于所述被寻呼的寻呼分组的数量,则每个被寻呼的寻呼分组关联一个随机接入前导,即被寻呼的寻呼分组与随机接入前导一对一关联;如果关联被寻呼的寻呼分组的随机接入前导的数量小于所 述被寻呼的寻呼分组的数量,则至少两个被寻呼的寻呼分组共用一个随机接入前导,例如:被寻呼的寻呼分组与随机接入前导采用循环复用方式关联,或每至少两个被寻呼的寻呼分组共用一个随机接入前导,也可以采用其它方式。

如果随机接入前导有3个,但被寻呼的寻呼分组有5个,则可以前导1关联分组1,4;前导2关联分组2,5;前导3关联分组3;即关联5个被寻呼的寻呼分组的前导索引依次为12312;也可以为11223,还可以为32132,12332,11332,12311等方式;总之需要有至少2个被寻呼的寻呼分组关联一个随机接入前导。

图2示出了本申请一个应用场景的示意图。
201,网络设备可以实时检测寻呼消息。
网络设备可以直接采用一个或多个方向的波束发送寻呼消息,即直接执行步骤206。应理解,下述实施例中可以将在执行步骤201之后直接执行步骤206的寻呼机制称为“波束扫描寻呼机制”。一个方向的波束可以对应一个SS/PBCH block。
202,网络设备在检测到寻呼消息到来时,采用每个终端设备对应的寻呼时机(paging occasion,PO)向相应地终端设备发送寻呼指示消息。
具体地,寻呼指示消息可以是控制资源信息和/或数据资源信息即可以在控制资源中传输,也可以在数据资源中传输,也可以是控制资源集合(Control Resource Set,CORESET),还可以是下行控制信息(Down link control information,DCI),其中,控制资源信息可以是物理下行控制信道(Physical Down Link Control Channel,PDCCH);该数据资源信息可以是物理下行共享信道(Physical Downlink Shared Channel,PDSCH)。同步信号块也可以称为同步信号/PBCH(Physical broadcast channel,物理广播信道),可以包含PBCH,PSS(primary synchronization signal,主同步信号),SSS(Secondary synchronization signal,辅同步信号)中的至少一个。

应理解,本申请实施例中,在寻呼时机中传输的信号可以是寻呼指示消息,也可以是寻呼消息,随机接入前导,还可以同时是寻呼指示消息和寻呼消息,本申请对此不仅限定。
还应理解,时间单元可以是帧、子帧、时隙或迷你时隙,本申请对此不进行限定。
也就是说,每个寻呼时机可以用于寻呼多个终端设备,而一个终端设备只能在一个 DRX周期内的一个寻呼时机上接收寻呼消息。
可选地,网络设备可以在步骤202之前,通过配置信息向终端设备发送寻呼时机中的信息或时频资源与同步信号块(Synchronous signal blocks,SS blocks)/物理广播信道(Physical Broadcast Channel,PBCH)块的映射关系,以及SS/PBCH块与随机接入时机周期中的随机接入时机的映射关系。寻呼时机中的信息可以是寻呼指示消息,可以是寻呼指示消息的控制信息,也可以是寻呼指示消息的数据信息,也可以是寻呼消息的数据信息,也可以是寻呼消息的控制信息。寻呼时机中的时频资源可以是寻呼指示消息的控制信息时频资源,也可以是寻呼指示消息的数据信息时频资源,也可以是寻呼信息的控制信息时频资源,也可以是寻呼信息的数据信息时频资源。
应理解,寻呼时机包括至少一个寻呼指示消息或寻呼消息,寻呼时机中的寻呼指示消息或寻呼消息与SS/PBCH块可以是一一对应,也可以是一对多,也可以是多对一的进行关联的。
应理解,随机接入时机与SS/PBCH块可以是一一对应,也可以是一对多,也可以是多对一的关联关系。
可选地,寻呼指示消息或寻呼消息与SS/PBCH块具有映射关系可以理解为在第一寻呼时机中传输寻呼指示消息或寻呼消息采用的波束与在SS/PBCH块传输SS/PBCH采用的波束相同。
本申请中的关联与也可以称为映射,对应,相关,分配。当随机接入周期或随机接入集合与寻呼时机相关的时候,可以为该寻呼时机的终端设备在该随机接入周期内的随机接入时机上发送随机接入前导,可以用于请求寻呼消息,或上报波束,随机接入时机和SS/PBCH block或寻呼时机中的寻呼消息或寻呼指示关联的时候,也可以表示它们具有准共址(quasi co-located,QCL)关系,可以采用相同的时延扩展或相同的多普勒扩展或相同的平均增益,相同的平均时延,或相同的空域参数发送或接收信号,或采用相同的波束发送或接收信号。
本文中使用i0+i*P1~i0+(i+1)*P1-1的形式表示关联到第j个项目2的项目1的索引号时,其中i0可以表示项目1的起始索引,当有多层关联关系的时候,可以与多个项目相关,P1可以表示项目1的数目,也可以表示关联到项目2的项目1数目,也可以表示项目2的数目,也可以表示关联到项目1的项目2数目,其有另外一种表达方式,即i=j0+floor(j/P1)或i=j0+ceil(j/P1)或i=j0+j/P1,两种表达是相同的意思,其中j0可以表示项目2的起始索引,j0可以与i0相关,P1等于1的时候,i=j1+j或者j=i0+i;还可以表达为关联到第i个项目1和第j个项目2的项目3的索引为i1+i+j*P2,也可以表达为i1+floor(i/Q1)+j*P2或i8+ceil(i/P2)+j*P3,还可以表达为关联到第i个项目1,第j个项目2和第k个项目3的项目4的索引为i2+i+j*P2+k*P3*P2,也可以表达为i2+floor(i/Q1)+j*P2+k*P3*P2或i2+ceil(i/Q1)+j*P2+k*P3*P2,其中P2为关联到项目1的项目4数目,P3为关联到项目2的项目4数目。其中项目1为寻呼分组,Q1表示共用项目4的项目1数目,SS/PBCH block,PO,随机接入前导,寻呼消息的窗口中的任意一个,项目2可以为寻呼分组,SS/PBCH block,PO,随机接入前导中的任意一个,项目3可以为寻呼分组,SS/PBCH block,PO,随机接入前导中的任意一个,项目4可以为寻呼分组,SS/PBCH block,PO,随机接入前导中的任意一个。
定义g(X,Y)可以表示为X/Y,也可以表示为floor(X/Y),还可以表示为ceil(X/Y)。
应理解,本申请实施例的同步信号块可以包括SS(Synchronization Signal,同步信号)和/或PBCH(Physical broadcast Channel,物理)。SS可以包含PSS,也可以包含SSS也可以同时包含PSS和SSS。
可选地,该寻呼指示消息可以携带寻呼分组的标识(identity,ID)。每个寻呼分组可以包括多个终端设备,且每个寻呼分组具体包括哪些终端设备可以是终端设备与网络设备预先配置的,也可以是预先约定的,可以按照一定的规则预先约定的。例如寻呼指示消息通过数据比特顺序对应不同的寻呼分组或不同的寻呼分组,例如寻呼指示消息通过数据比特对应不同的寻呼分组或不同的寻呼分组。
可选地,终端设备在接收到的寻呼指示消息不携带寻呼分组的ID的情况下,可以直接执行步骤204。应理解,在下述实施例中可以将执行步骤201,202,205,206的寻呼机制称为“基于反馈的寻呼机制”。
203,终端设备接收到寻呼指示消息后,检测该终端设备所在的寻呼分组是否被寻呼。
在寻呼指示消息携带寻呼分组的ID的情况下,终端设备根据该寻呼分组的ID的信息确定自己是否在组内。如果不在组内,则表示没有被寻呼,不需要执行后续步骤。
204,终端设备根据该终端设备对应的寻呼时机中接收的寻呼指示消息,确定随机接入时机。
具体地,寻呼时机中能够接收到的寻呼指示消息与SS/PBCH块对应,SS/PBCH块与随机接入时机周期中的随机接入时机具有映射关系。终端设备根据接收的寻呼指示消息,确定在第一寻呼时机接收到的寻呼指示消息对应的SS/PBCH块,再根据该SS/PBCH块确定随机接入时机周期(Random access channel occasion,RO)中的随机接入时机。
需要说明的是,随机接入时机周期可以包括至少一个随机接入时机。在随机接入时机周期中包括多个随机接入时机的情况下,也可以将该随机接入时间周期包括的随机接入时机称为“随机接入时机组”,或“随机接入时机集合”。该第一随机接入时机可以是在任意一个随机接入时机周期相同的位置。
应理解,随机接入时机周期可以为随机接入资源关联周期,也可以为随机接入资源配置周期,也可以为随机接入资源关联周期的一部分,也可以为随机接入资源配置周期的一部分。随机接入时机周期资源配置周期。随机接入时机周期可以理解为发送随机接入资源所占的时间数量或者时间宽度;或者发送RO所占的数量。
应理解,本申请实施例中的随机接入时机的周期可以为10ms、20ms、40ms、80ms和160ms中的任意一项。
205,终端设备向网络设备发送随机接入前导。
终端设备在接收到寻呼指示消息之后的任意一个或者多个随机接入时机周期中的第一随机接入时机上发送随机接入前导。
可选地,在步骤203之后,若终端设备不在该寻呼分组中,则该终端设备可以转入休眠状态;若终端设备在该寻呼分组中,则向网络设备发送随机接入前导,随机接入前导可以用于指示终端设备所在的寻呼分组。
206,网络设备根据随机接入前导向至少一个终端设备发送寻呼消息。
具体地,网络设备可以确定每个随机接入前导为哪个终端设备发送的,进而可以向反馈随机接入前导的终端设备发送寻呼消息,且每个寻呼消息携带有终端设备的ID。
可选地,该寻呼消息还可以携带***更新消息、地震灾害消息、火山灾害消息和海啸 灾害消息等灾害预警的消息。
应理解,下述实施例中将执行步骤201-206的部分或者全部的步骤反馈机制称为“基于寻呼分组以及反馈的寻呼机制”。
上述方案中,若采用如图2中的“基于反馈的寻呼机制”和“基于寻呼分组以及反馈的寻呼机制”,由于通常情况下,每个寻呼分组均关联一个随机接入前导,因此,随机接入前导的占用的数量较多,开销较大,另外,由于小区中一个随机接入时机的随机接入前导总数量固定,导致其它业务的使用的随机接入前导不足。
通常情况下,一个波束、一个SS/PBCH block(也称为SS block)或一个寻呼时机对应一个寻呼指示消息,以下以一个波束的寻呼指示消息为例进行说明,多个波束的情况的情况类似。
在一些实施例中,可以将寻呼指示中每个的寻呼分组分配一个随机接入前导,也可以至少2个寻呼分组共用一个或多个随机接入前导。
例如:寻呼指示消息中携带的寻呼指示为01110000,每个比特代表一个寻呼分组,其中1表示该分组被寻呼,0表示该分组没有被寻呼(反之亦可);则上述8个分组中共有3个分组(第2、3、4个)被寻呼,5个分组没有被寻呼,此时可以为每个寻呼指示(不管是否被寻呼)分配一个随机接入前导,则共分配8个随机接入前导。
另外也可以设置2个分组共用1个前导,分组信息为01110000时,则前2个分组0和1共用一个前导1,第3个分组1和和第四个分组1共用一个前导2,第5个分组0和第6个分组0共用一个前导3,最后2个分组0和0共用一个前导4,一共只需要分配4个前导即可。另外,可以按分组顺序分配共享的前导,也可以不按顺序,随意2个分组共享一个前导。例如分配的4个前导(索引为1,2,3,4)给上述8个分组,前导索引依次为12341234(或43214321),此种关联方式称为循环复用;也可以为12344321,11223344,22113344,等其它方式。当然也可以设置3个或3个以上分组共用一个前导。例如:前三个分组011共用一个前导,中间两个分组100共用一个前导,剩下两个分组00共用一个前导。
综上所述,可以为每个寻呼分组(不管是否被寻呼)分配一个随机接入前导,也可以设置至少2个寻呼分组共用一个随机接入前导,也可以配置一个随机接入前导关联的寻呼分组的数目N,或者设置K个寻呼分组共同关联一个随机接入前导。总之,当寻呼分组数量大于随机接入前导数量时,由于随机接入前导数量不够,需要重复使用;可以采用循环复用的方式为寻呼分组分配随机接入前导,但不限于上述方式,只需要一部分寻呼分组共同使用一个或多个随机接入前导即可。
另外,也可以设置用于关联寻呼分组的随机接入前导数目M3,M3与以下参数至少一种相关:
用于寻呼的随机接入前导数目N1,一个随机接入时机关联的SS/PBCH block数目M1,一个随机接入时机关联的寻呼时机数目M2;例如:
M3=f(N1,M1,M2),其中f(N1,M1,M2)可以为N1/(M1*M2),floor(N1/(M1*M2)),ceil(N1/(M1*M2)),floor(floor(N1/M1)/M2),floor(floor(N1/M2)/M1),ceil(ceil(N1/M1)/M2),ceil(ceil(N1/M2)/M1),floor(ceil(N1/M1)/M2),floor(ceil(N1/M2)/M1),ceil(floor(N1/M1)/M2),ceil(floor(N1/M2)/M1),N1/M1,floor(N1/M1),ceil(N1/M1),N1/M2,floor(N1/M2),ceil(N1/M2),N1中的任意一个。
网络设备也配置M3的取值、N1或N的取值,还可以与终端设备预先约定M3的取值、N1的取值或N的取值,N1,N或M3的取值通常可以为1~64中的任意一个正整数值。但最大值不限于64,也可以为128、265等;M3的值也可以与寻呼分组的数目相同。
以下以公式方式举例说明随机接入前导与寻呼分组的关联关系:
关联到随机接入前导索引为i1的寻呼分组索引为i2,则i1=i0+g(i2,M3,N);例如:g(i2,M3,N)可以为floor(i2/N),也可以为i2,还可以为ceil(i2/N),也可以为i2mod M3。也可以反过来,即关联到随机接入前导为i1的寻呼分组索引为i2的取值为i0+i1*N~i0+(i1+1)*N-1。
i0的取值可以与以下一个或多个参数相关:一个随机接入时机关联的SS/PBCH block数目,一个随机接入时机关联的寻呼时机数目,该随机接入前导关联的SS/PBCH block索引,该随机接入前导关联的寻呼时机索引,关联寻呼分组的随机接入前导数目。
上述实施例中,不管分组是否被寻呼,均与随机接入前导进行关联;在另外一些实施例中,可以只将被寻呼的寻呼分组与随机接入前导进行关联,不需要为没有被寻呼的寻呼分组分配随机接入前导,仅需要为被寻呼的寻呼分组分配随机接入前导。
一种方法是所有的被寻呼的寻呼分组中的每一个分组关联一个随机接入前导。
例如:寻呼指示消息中携带的寻呼指示为01110000,每个比特代表一个寻呼分组,其中1表示该分组被寻呼,0表示该分组没有被寻呼(反之亦可);则8个分组中共有3个分组(第2、3、4个)被寻呼,5个分组没有被寻呼,则不需要为每个分组分配随机接入前导,仅需要为第2、3、4个分组分配随机接入前导,则此时只需要3个随机接入前导,从而节省了随机接入前导的数目。例如:分配的随机接入前导的索引依次为123,也可以为321、132或231,只要一个被寻呼的寻呼分组关联一个随机接入前导即可。
被寻呼的寻呼分组数目为M4,关联到被寻呼的寻呼分组的随机接入前导数目为N3,上述例子中M4=N3,关联到被寻呼的寻呼分组索引为i1的随机接入前导索引为i2,则i1=i0+i2。
i0的取值可以与至少一个参数相关:一个随机接入时机关联的SS/PBCH block数目,一个随机接入时机关联的寻呼时机数目,该随机接入前导关联的SS/PBCH block索引,该随机接入前导关联的寻呼时机索引。
另外一种方法是,至少2个被寻呼的寻呼分组共同关联一个随机接入前导。
例如:寻呼指示为01110000,表示共有3个分组被寻呼,则可以第2、3个分组共用一个前导,第4个分组共用一个前导;也可以第2、4个分组共用一个前导,第3个分组共用一个前导,只需要2个前导即可。这样进一步节省了随机接入前导的数量。
也可以预先设置关联被寻呼的寻呼分组的随机接入前导的数量M5,如果M5大于等于被寻呼的寻呼分组的数量,则可以为每个被寻呼的寻呼分组分配一个随机接入前导;上面例子中M5=3,由于8个寻呼分组中共有3个分组(第2、3、4个)被寻呼,则可以为每个分组分配一个随机接入前导。
如果M5小于被寻呼的寻呼分组的数量,例如寻呼指示为01111000,表示有4个分组(第2、3、4、5个)被寻呼,关联被寻呼的寻呼分组的随机接入前导只有3个(索引为1、2、3),则可以至少两个分组共用一个随机接入前导,例如,第2、5个分组共用随机接入前导1,第3、4个分组关联的随机接入前导分别为2、3;即4个被寻呼的寻呼分组的关联的随机接入前导的索引依次为1231。即,前导分配完了,重新开始从头分配,这 种方式可以称为循环复用。
上述举例是M5小于被寻呼的寻呼分组的数量时,由于随机接入前导数量不够,采用循环复用的方式为被寻呼的寻呼分组分配随机接入前导,但不限于上述方式,只需要一部分寻呼分组共同使用一个或多个随机接入前导即可。比如:第2、3分组共用随机接入前导1,第4、5分组分别使用随机接入前导2、3。其它关联方式亦可,比如上述4个被寻呼的寻呼分组的关联的随机接入前导的索引还可以为1123,3212,1233或1233等各种分配方式。
比如,有6个分组被寻呼,而M5=3,即只有三个随机接入前导(索引为1、2、3),则6个分组关联前导的方式可以为123123,112233,123321,113322,111223等各种方式,总之前导数量不够,需要被多个被寻呼的分组重复使用。
寻呼指示消息可以通过不同的波束进行发送,但携带的内容通常是相同的,例如4个波束携带的寻呼指示消息均为01010000,即,共有2个分组被寻呼(第2、4个),通过4个波束发送,可以为每个波束的被寻呼的分组分别分配一个随机接入前导,比如,波束1的2个分组分配前导1,2,波束2的2个分组分配前导3,4,波束3的2个分组分配前导5,6,波束4的2个分组分配前导7,8;即被寻呼的分组24242424分配的随机接入前导分别为12345678。如果M5小于8,则此时随机接入前导的数量不够,例如M5=3,只有3个前导供分配,索引分别为1,2,3;则被寻呼的寻呼分组24242424分配的随机接入前导索引可以为12312312,11223311,12332112,11332233等多种方式,还可以有其它分配方式,总之需要多个被寻呼的寻呼分组共用一个或多个随机接入前导。每一个寻呼指示消息的波束可以对应一个SS/PBCH block,也可以对应多个SS/PBCH block。波束也可以称为空域参数。
由此可以看出,随机接入前导不够分配时,可以用循环复用的方式来为多余的寻呼分组分配前导,也可以用每至少2个分组共用一个前导的方式来分配,也可以采用乱序的方式来分配前导,也可以采用随机的方式来分配前导,还可以有其它方式。
M5的值的范围可以是变化的,可以为1~64中的全部或部分值,例如为2、4、6、8。M5的值也可以是固定的,即网络设备与终端设备约定的,可以是1~64中的任意一个值。但最大值不限于64,也可以为128,256等。
另外,M5的值可以通过计算得到,通常与以下至少一个参数相关:用于寻呼的随机接入前导数目N1、一个随机接入时机关联的SS/PBCH block数目M1,一个随机接入时机关联的寻呼时机数目M2。
例如:M5=f(N1,M1,M2),其中f(N1,M1,M2)可以为N1/(M1*M2),floor(N1/(M1*M2)),ceil(N1/(M1*M2)),floor(floor(N1/M1)/M2),floor(floor(N1/M2)/M1),ceil(ceil(N1/M1)/M2),ceil(ceil(N1/M2)/M1),floor(ceil(N1/M1)/M2),floor(ceil(N1/M2)/M1),ceil(floor(N1/M1)/M2),ceil(floor(N1/M2)/M1),N1/M1,floor(N1/M1),ceil(N1/M1),N1/M2,floor(N1/M2),ceil(N1/M2),N1中的任意一个。
上面给出几种计算方式,应当理解这些计算方式仅仅是举例,不限于上述计算方式。
另外,M5的取值可以与终端设备或者网络设备的DRX周期相关,每一个终端设备或网络设备的DRX周期可以有一个M5的取值,或者多个终端设备或网络设备的DRX周期有一个M5的取值,例如2个或4个终端设备或网络设备的DRX周期有一个M5的取值。每个DRX周期的M5的取值也可以按上面的方法进行计算。
网络设备可以配置M5的取值、N1或N的取值,还可以与终端设备预先约定M5的取值、N1的取值或N的取值,N1,N或M5的取值通常可以为1~64中的任意一个正整数值。但最大值不限于64,也可以为128、265等;M5的值也可以与寻呼分组的数目相同。
当被寻呼的寻呼分组数目大于M5的时候,关联到随机接入前导索引为i1的被寻呼的寻呼分组索引为i2,则i1=i0+g(i2,M6,M5),g(i2,M6,M5)可以为floor(i2/M6),也可以为i2,还可以为ceil(i2/M6),也可以为i2mod M5。M6可以表示一个随机接入前导关联的被寻呼的寻呼分组数目。被寻呼的寻呼分组索引是指将寻呼分组中被寻呼的寻呼分组索引排序之后的寻呼分组索引,例如寻呼指示为01001000,寻呼分组中只有寻呼分组1和寻呼分组4被寻呼,即只有两个寻呼分组被寻呼,将两个寻呼分组按照顺序排列,寻呼分组1对应被寻呼分组的索引0,寻呼分组4对应被寻呼分组的索引1。i2表示寻呼分组中被寻呼的寻呼分组按照顺序重排之后的寻呼分组索引。该顺序可以是索引号从小到大也可以是索引号从大到小也可以是随机的顺序进行排列。
i0的取值可以与以下至少一个参数相关:一个随机接入时机关联的SS/PBCH block数目,一个随机接入时机关联的寻呼时机数目,该随机接入前导关联的SS/PBCH block索引,该随机接入前导关联的寻呼时机索引,关联被寻呼的寻呼分组的随机接入前导的数目。
网络设备也配置M6的取值或者配置M5的取值,还可以与终端设备预先约定M6的取值或M5的取值,M5的取值可以为1~64中的任意一个正整数值。M6的取值也可以为1~64中的任意一个正整数值。M5的取值可以与M6相关,一种相关的方式为M6=ceil(N3/M5),M6=floor(N3/M5),M6=N3/M5。当网络设备配置M5的取值的时候,配置的值为1~64中的部分或者全部值,例如,可以为2,4,8,16。
本申请中Mod或mod表示求余,ceil表示向上取整,floor表示向下取整。“/”在公式中表示两个数相除。
以下列举一种关联方式:
例如j0表示可以用于寻呼的随机接入前导的起始索引,可以为常数,该常数可以为0,也可以是其它数,可以通过网络配置或者通过网络配置的参数推导出。参数1和参数2可以分别表示关联一个随机接入时机或资源的SS/PBCH块数目,和关联一个随机接入时机或资源的寻呼时机数目,表示顺序可以任意;M7可以表示参数1的数目,M8可以表示参数2的数目,i0可以为j0+i1*M5或j0+i1*M5+i2*M5*M7;例如用于寻呼的随机接入前导的索引j0从4开始,参数1为寻呼时机的数目为2,参数2为SS/PBCH块的数目为3,关联到寻呼分组的随机接入前导数目为2,则共需要12个随机接入前导,其索引为4,5,6,7,8,9,10,11,12,13,14,15,则第一个寻呼时机的第一个SS/PBCH块下的寻呼分组的i0表示为4,第一个寻呼时机的第二个SS/PBCH块下的寻呼分组的i0表示为6,第一个寻呼时机的第三个SS/PBCH块下的寻呼分组的i0表示为8,第二个寻呼时机的第一个SS/PBCH块下的寻呼分组的i0表示为10,依次类推。
上述各个实施例中,M3、M5、M6、N1及N的值可以是网络设备与终端设备预先约定的,也可以是标准定义的,也可以是网络设备配置的,并发送给终端设备,配置信息可以承载在物理广播信道(Physical Broadcast Channel,PBCH)、RMSI、***信息块(System Information Block,SIB)1、SIB2、SIB3、媒体接入控制控制元素(Media Access control-control element,MAC-CE)、下行控制信息(Down link control information,DCI)、无线资源控 制(Radio Resource Control,RRC)信令以及***信息中的任意一项或多项中。
同理也可以通过不同的随机接入时机关联不同的被寻呼的寻呼分组或者联合不同的随机接入时机和不同的随机接入前导通过关联不同的被寻呼分组。当使用随机接入时机关联不同的被寻呼分组的时候,可以上面的随机接入前导可以替换为随机接入时机。当联合不同的随机接入时机和不同的随机接入前导通过关联不同的被寻呼分组的时候,随机接入时机和随机接入前导可以统称为随机接入资源,随机接入资源的数目可以为随机接入时机和随机接入前导的积,也可以为上面的随机接入前导可以替换为随机接入资源。
上述各个实施例中,寻呼分组与随机接入前导的关联关系,或被寻呼的寻呼分组与随机接入前导的关联关系可以由标准规定,网络设备或终端设备事先已经获知,也可以由网络设备或终端设备分别进行配置,或者由网络设备配置后发送给终端设备,配置信息通过上面段落提到的各种消息携带。

以下结合附图4以及上述提到的寻呼分组与随机接入前导的关联方式,对完成寻呼过程进行说明,以下以一个终端设备和一个网络设备为例进行说明:
401-402,网络设备向终端设备发送寻呼指示,寻呼指示中携带有多个寻呼分组的信息;
该步骤同步骤201-202类似,多个分组的信息比如为01110000,1表示被寻呼,0表示未被寻呼。
网络设备可以通过多个波束来发送上述寻呼指示,便于不同位置的终端设备接收。
403,终端设备接收到寻呼指示后,检测该终端设备所在的寻呼分组是否被寻呼;
该步骤与203类似。如果终端设备处于上述被寻呼的寻呼分组中,比如,处于第二个分组,则继续进行下面的步骤,否则,不进行相关操作,例如,如果处于第一个分组,标识没有被寻呼。
404,终端设备根据关联关系确定随机接入前导;
上述的关联关系可以是上面各个实施例提到的:所述多个寻呼分组中被寻呼的寻呼分组与随机接入前导的关联关系;也可以是所述多个寻呼分组与随机接入前导的关联关系;关于上述关联关系,前文已经详细介绍并举例说明,这里不再进一步说明。
另外,终端设备还根据寻呼指示确定随机接入时机等随机接入资源,这部分内容同204类似,不再详述。
405,终端设备向网络设备发送所述随机接入前导。
406,网络设备接收到所述随机接入前导后,向所述终端设备发送寻呼消息。
405-406与205-206类似,不再详述。
上述方案只是寻呼流程的简化,重点在于如何根据所述关联关系确定终端设备所述的寻呼分组关联的随机接入前导,其它的流程及细节可以参加图2的实施例,这里不再详述。
上述实施例中的关联关系可以标准定义的,也可以是网络设备与终端设备预先约定的,也可以是网络设备配置的,并发送给终端设备,配置信息可以承载在物理广播信道 (Physical Broadcast Channel,PBCH)、RMSI、***信息块(System Information Block,SIB)1、SIB2、SIB3、媒体接入控制控制元素(Media Access control-control element,MAC-CE)、下行控制信息(Down link control information,DCI)、无线资源控制(Radio Resource Control,RRC)以及***信息中的任意一项中。
另外,上述实施例提到的M3,M5,M6,N,N1的值中的一个或多个,也可以是网络设备与终端设备预先约定的,也可以是网络设备配置的,并发送给终端设备,配置信息也可以承载在上述消息中。
