技术领域
本申请涉及通信技术领域,尤其涉及一种下行控制信息DCI的发送方法及装置。
背景技术
为了减小终端设备的功耗,在第五代移动通信技术(5th generation,5G)新空口(new radio,NR)系统中可能会引入节能信号/信道(power saving signal/channel)。节能信号可以与无线资源控制(radio resource control,RRC)连接态下的非连续接收(discontinuous reception,DRX)机制相结合。对于支持节能信号的终端设备,网络设备可以为终端设备以DRX的形式发送节能信号。
对于节能信号的设计,一种可能的方案是复用现有的NR中物理下行控制信道(physical downlink control channel,PDCCH)的设计。即,将节能信号设计成下行控制信道,例如PDCCH,终端设备通过检测相应的PDCCH获取网络设备发送的节能信息。
现有技术中,节能信号可以为终端设备特定(UE specific)的PDCCH,也可以为面向终端设备组(UE Group)的PDCCH。面向UE Group的PDCCH是指,网络设备可以为一组终端设备配置检测同一个Group PDCCH,该Group PDCCH承载了Group DCI,用于指示该组中每个终端设备的相应的节能信息(比如是否“唤醒”)。Group DCI中包含多个信息块,每个信息块可对应该组终端设备中的其中一个终端设备,其中包含该终端设备的节能信息。
由于Group DCI中所能携带的信息的比特数是有限的,限制了该Group DCI中能够包含的信息块的数量。在一些情况下,网络设备也并不需要同时指示该组内所有终端设备的节能信息。因此,网络设备在发送Group DCI时,可仅指示该组内部分终端设备的节能信息。然而,目前的Group DCI总是按照一个预设顺序,优先指示顺序靠前的终端设备的节能信息,不利于顺序靠后的终端设备获取节能信息。
发明内容
本申请实施例提供一种下行控制信息DCI的发送方法及装置,用于使一组终端设备都有机会获得Group DCI中的节能信息,充分发挥节能信号的节能作用。

实施例一
请参考图2,为本申请实施例提供的一种DCI的发送方法的流程示意图,该方法具体包括如下的步骤S201至步骤S204。
步骤S201、网络设备确定DCI,该DCI包括指示信息和m 1个信息块。该DCI可以为针对N个终端设备的节能信号,N为正整数。该N个终端设备可以属于一个终端设备组,即,该DCI为针对该终端设备组的节能信号。该节能信号也可以称为唤醒信号,也可以具有其他名称,具体并不限定。
所述指示信息用于指示该组终端设备包括的全部N个终端设备中的b 1个终端设备,该b 1个终端设备具体是指N个终端设备中需要检测节能信息的终端设备,因此,该指示信息也可以理解为,用于指示N个终端设备中的哪些终端设备需要检测节能信息。该指示信息也可以称为UE指示域、或者节能指示域、或者唤醒指示域,或者具有其他名称,本申请并不限定。此处,b 1为正整数,且满足b 1小于等于N。由b 1小于等于N可知,在该N个终端设备组成的终端设备组中可以有全部或部分的终端设备需要检测节能信息。
步骤S202、网络设备向上述N个终端设备发送该DCI。
步骤S203、终端设备从网络设备接收该DCI,该终端设备为上述b 1个终端设备之一。
步骤S204、终端设备根据指示信息和DCI的时域信息,在m 1个信息块中确定用于指示该终端设备的节能信息的信息块,所述时域信息包括DCI所在的帧的帧号和/或DCI所在的时隙的时隙号。
下面对上述步骤S201至步骤S204,以及各步骤中涉及到的概念进行详细介绍。
本申请实施例中,DCI中包括的指示信息可具有多种可能的实现方式。在一种可能的设计中,该指示信息可以为第一比特序列,该第一比特序列包括N个比特,每个比特与N个终端设备中的一个终端设备相对应,这里,可以理解为每个比特对应不同的终端设备,即,N个比特与N个终端设备一一对应,每个比特用于指示该比特对应的终端设备是否需要检测节能信息。每个比特可具有第一状态值和第二状态值两种取值,例如,第一状态值可以为1,第二状态值可以为0。当一个比特的取值为第一状态值时,可表示该比特对应的终端设备需要检测节能信息,即该比特对应的终端设备为上述b 1个终端设备中的终端设备。当一个比特的取值为第二状态值时,可表示该比特对应的终端设备不需要检测节能信息,即该比特对应的终端设备不在b 1个终端设备中。由此,通过第一比特序列中的N个比特的取值,可指示出N个终端设备中的b 1个终端设备。在另一种可能的设计中,指示信息可以为第一比特序列在多个可选的比特序列中的索引,用以间接地指示该第一比特序列。
应理解,所述第一比特序列也可以称为第一位图(bitmap)。在实际应用中,第一状态值和第二状态值也可以为其它取值,例如,第一状态值可以为非0值,第二状态值可以为0,本申请并不限定。
图3为本申请实施例提供的一种第一比特序列的示意图。该第一比特序列中包括8个比特,表示N=8,即终端设备组中包括8个终端设备。8个比特分别与8个终端设备一一对应,按照比特位由高到低的顺序,第一比特序列中的8个比特对应的终端设备分别为UE0、UE1、UE2、UE3、UE4、UE5、UE6和UE7。在8个比特中有5个比特的取值为1,分别为第1个比特、第2个比特、第4个比特、第5个比特、第7个比特,因此,UE0至UE7中的b 1个终端设备包括UE1、UE2、UE4、UE5和UE7,b 1=5。
本申请实施例中,DCI中包括的m 1个信息块中的每个信息块,用于指示对应终端设备的节能信息。该节能信息可以为下述信息中的一个或多个:例如带宽区域标识(bandwidth part identifier,BWP ID)指示、同时隙或跨时隙调度(cross-slot or same-slot scheduling)指示、参考信号(reference signal,RS)传输指示(包括非周期信道状态参考信号(channel  state information reference signal,CSI-RS)、T(tracking,跟踪)RS、信道探测参考信号(sounding reference signal,SRS)、信道状态信息(channel state information,CSI)上报、单载波或多载波指示(即指示终端设备是否使用多个载波接收数据)、终端设备是否在DRX激活时间检测PDCCH、UE是否“唤醒”等;或者,该节能信息还可以为:终端设备需要检测或停止检测PDCCH的CORESET或搜索空间集合或候选PDCCH;终端设备检测搜索空间集合的周期;终端检测PDCCH的周期(PDCCH monitoring periodicity);终端设备停止检测PDCCH一段时间(PDCCH skipping);终端设备接收天线数或多输入多输出(multiple-input multiple-output,MIMO)层数;终端设备需要检测或停止检测PDCCH的载波(比如可以为辅载波,这里,辅载波也可以称为辅小区(SCell))。
m 1个信息块中的每个信息块与上述指示信息所指示的b 1个终端设备中的一个终端设备相对应,这里,可以理解为每个信息块对应不同的终端设备。m 1为正整数,且满足m 1小于等于b 1,即m 1≤b 1≤N。可以理解,m 1等于b 1时,可表示b 1个终端设备中的每个终端设备在该DCI包括的m 1个信息块中都有对应的信息块,即,m 1个信息块与b 1个终端设备一一对应。而m 1小于b 1时,可表示只有b 1个终端设备中的部分终端设备在该DCI包括的m 1个信息块中存在对应的信息块,m 1个信息块与b 1个终端设备中的部分终端设备一一对应,也就是说,即该DCI中仅包含N个终端设备中的部分终端设备的节能信息。
图4为本申请实施例提供的一种DCI的结构示意图。如图4所示,该DCI中包括的指示信息可位于m 1个信息块之前。可选地,在m 1个信息块之后,该DCI中还可包括循环冗余校验(cyclic redundancy check,CRC)序列。
为了避免N个终端设备中的每个终端设备获得节能信息的机会相差过大,在步骤S201中,网络设备可根据该DCI中的指示信息和该DCI的时域信息,对DCI中包括的m 1个信息块进行随机化处理,进而生成该DCI。随机化处理的过程也可以理解为,确定DCI中应包括b 1个终端设备中的哪些终端设备对应的信息块的过程。
m 1个信息块分别对应的终端设备,或者说,m 1个信息块与b 1个终端设备之间的对应关系,可根据该DCI中的指示信息和该DCI的时域信息确定。此处,DCI的时域信息可包括DCI所在的帧的帧号和/或DCI所在的时隙的时隙号。也就是说,在确定DCI之后,DCI中包括的m 1个信息块中的每个信息块在b 1个终端设备中对应的终端设备、以及b 1个终端设备中的每个终端设备是否在m 1个信息块中存在对应的信息块,若存在对应的信息块,该终端设备具体对应m 1个信息块中的哪个信息块,均可根据该DCI中的指示信息和该DCI的时域信息确定。
具体的,网络设备确定DCI的过程,或者说网络设备对m 1个信息块进行随机化的过程,可包括:网络设备根据DCI的时域信息,确定第一循环移位值,然后根据该第一循环移位值,对第一比特序列的全部或部分进行循环移位,以确定m 1个信息块分别对应的终端设备。这一过程又可具有如下的两种可能的实现方式:
第一种可能的实现方式:
DCI中的指示信息为第一比特序列,网络设备可根据第一循环移位值对该第一比特序列进行循环移位,得到第二比特序列;进而确定该DCI包括的m 1个信息块中的第i个信息块对应的终端设备为第二比特序列中第i个取值为第一状态值的比特所对应的终端设备。
应理解,第二比特序列是对第一比特序列进行循环移位得到的,该第二比特序列也包括N个比特,且第二比特序列中的第q i个比特为第一比特序列中的第q j个比特,其中,q i和 q j满足关系:q j=(q i-1+p 1)modN+1,所述p 1为第一循环移位值。
虽然对第一比特序列进行了循环移位,但是循环移位过程并不会改变每个比特对应的终端设备。也就是说,第一比特序列中的第q j个比特对应的终端设备,与循环移位后得到的第二比特序列中的第q i个比特对应的终端设备相同。此外,进行循环移位也不会改变每个比特的取值所代表的含义。在第二比特序列中,取值为第一状态值的比特对应的终端设备仍表示该终端设备属于上述b 1个终端设备,需要检测节能信息。
图5示例性示出了在第一种可能的实现方式中,网络设备确定DCI中的m 1个信息块对应的终端设备的过程。在图5这一示例中,第一比特序列为01101101,第一循环移位值为3。第一比特序列中的各个比特按照比特位从高到低的顺序,依次对应终端设备UE0、UE1、UE2、UE3、UE4、UE5、UE6和UE7。利用第一循环移位值3对第一比特序列01101101进行循环移位,可得到第二比特序列01101011。第二比特序列中的各个比特按照比特位从高到低的顺序,依次对应终端设备UE3、UE4、UE5、UE6、UE7、UE0、UE7和UE2。
如此,根据m 1个信息块中的第i个信息块对应的终端设备为第二比特序列中第i个取值为第一状态值的比特所对应的终端设备可知,若m 1=4,则该DCI中包括的4个信息块分别为UE4、UE5、UE7和UE1对应的信息块。
在该第一种实现方式中,第一循环移位值可通过如下的任一方式确定:
Figure PCTCN2020090901-appb-000019
或,
Figure PCTCN2020090901-appb-000020
或,
p 1=(n f+n s,f)mod N;
其中,p 1为第一循环移位值,n f为DCI所在的帧的帧号,n s,f为DCI所在的时隙的时隙号,
Figure PCTCN2020090901-appb-000021
为一个帧中包含的时隙的数量,k s为DCI的检测周期,mod表示求模运算。
需要说明的是,在第一种实现方式中,DCI中所能容纳的信息块的比特总数是一定的,且每个信息块中所能容纳的信息的比特数也是固定的,因此DCI中能够包括的信息块的总数也是固定的。
假设DCI中最多能够包含M 1个信息块,M 1为正整数。本申请实施例中,网络设备通过DCI中的指示信息指示的需要检测节能信息的终端设备的数量b 1,可以小于等于M 1,也可以大于等于M 1
当b 1小于等于M 1时,m 1=b 1≤M 1。表示DCI中所包括的信息块的数量m 1与DCI的指示信息指示的需要检测节能信息的终端设备的数量b 1相等。此时,DCI的指示信息中指示的需要检测节能信息的b 1个终端设备,在该DCI包括的m 1个信息块中均存在对应的信息块。
当b 1大于M 1时,m 1=M 1≤b 1。表示DCI中实际上包括M 1个信息块,已经达到了DCI中所能容纳的信息块的数量的上限。由于DCI的指示信息中指示的需要检测节能信息的终端设备的数量b 1,大于该DCI中实际包括的信息块的数量M 1。因此,DCI的指示信息中指示的b 1个终端设备中会存在部分终端设备,在该DCI包括的M 1个信息块没有对应的信息块。
例如,图5中所示的UE2。虽然第二比特序列中与UE2对应的比特的取值为1,但是由于UE2对应的比特为第二比特序列中的第5个取值为1的比特,而该DCI中最多只能包括4个信息块,所以UE2在DCI中不存在对应的信息块。
若某一终端设备属于需要检测节能信息的b 1个终端设备,但该DCI中却不包括该终端设备对应的信息块。在这种情况下,该终端设备可以使用默认配置下的节能信息。例如, 网络设备可以通过高层信令为终端设备预配置一些节能信息的取值,称为默认配置(default configuration)。
需要注意的是,本申请实施例中,DCI的大小可以是半静态变化的,终端设备通常可以按照相同的大小来检测DCI。如果该DCI中实际包括的信息块的数量m 1,小于该DCI所能包括的最多的信息块的数量M 1时,那么该DCI中还可以存在一些填充比特(padding bits),图4中未示出。
第二种可能的实现方式:
指示信息为第一比特序列,网络设备可根据第一比特序列确定第三比特序列,该第三比特序列包括第一比特序列的N个比特中,与b 1个终端设备相对应的b 1个比特;网络设备根据第一循环移位值对第三比特序列进行循环移位,得到第四比特序列;进而确定DCI包括的m 1个信息块中的第i个信息块对应的终端设备为第四比特序列中的第i个比特所对应的终端设备。
应理解,第一比特序列中与b 1个终端设备相对应的b 1个比特,为第一比特序列中比特的取值为第一状态值的b 1个比特。这b 1个比特中的每个比特均用于指示对应的终端设备需要检测节能信息。通过提取第一比特序列中比特的取值为第一状态值的b 1个比特,得到第三比特序列,可以说该第三比特序列是第一比特序列的其中一部分。第三比特序列中的每个比特对应的终端设备,仍与该比特在第一比特序列中对应的终端设备相同。且该第三比特序列包括的b 1个比特中的每个比特,均用于指示对应的终端设备需要检测节能信息。
图6示例性示出了在第二种可能的实现方式中,网络设备确定DCI中的m 1个信息块对应的终端设备的过程。在图6这一示例中,第一比特序列为01101101,按照比特位从高到低的顺序,第一比特序列中的各个比特对应的终端设备分别为UE0、UE1、UE2、UE3、UE4、UE5、UE6、UE7。第一比特序列中包括5个比特的取值为1的比特,因此,b 1=5。通过提取第一比特序列中比特的取值为1的各个比特,可得到第三比特序列为11111。按照比特位从高到低的顺序,第三比特序列中的各个比特对应的终端设备分别为UE1、UE2、UE4、UE5和UE7。
下一步,采用第一循环移位值3对第三比特序列进行循环移位,可得到第四比特序列11111。虽然从表面上看,第四比特序列与第三比特序列相同,但是第四比特序列中的各个比特对应的终端设备与第三比特序列是不同的。按照比特位从高到低的顺序,第四比特序列中的各个比特对应的终端设备分别为UE5、UE7、UE1、UE2和UE4。
根据m 1个信息块中的第i个信息块对应的终端设备为第四比特序列中的第i个比特所对应的终端设备可知,若m 1=4,该DCI中包括的4个信息块分别为UE5、UE7、UE1和UE2对应的信息块。
在该第二种实现方式中,第一循环移位值可通过如下的任一方式确定:
Figure PCTCN2020090901-appb-000022
或,
Figure PCTCN2020090901-appb-000023
或,
p 1=(n f+n s,f)mod b 1
其中,p 1为第一循环移位值,n f为DCI所在帧的帧号,n s,f为DCI所在的时隙的时隙号,
Figure PCTCN2020090901-appb-000024
为一个帧中包含的时隙的数量,k s为DCI的检测周期,mod表示求模运算。
需要说明的是,在第二种实现方式中,DCI中包括的每个信息块所能容纳的信息的比特数可以是固定的,也可以是灵活设置的。由于DCI中所能容纳的信息块的比特总数是一 定的,若每个信息块中所能容纳的信息的比特数也是固定的,那么与第一种实现方式中类似,该DCI中所能包括的信息块的总数也是固定的,例如可以是M 1。此时,也是有可能存在某个终端设备属于DCI中的指示信息所指示的需要检测节能信息的b 1个终端设备,但是该DCI中却不包括该终端设备对应的信息块的情况。这就需要终端设备采用预配置的节能信息。
若DCI中包括的每个信息块中所能容纳的信息的比特数可以是灵活设置的,那么网络设备可根据该DCI中所能容纳的信息块的比特总数、以及需要检测节能信息的终端设备的数量b 1,确定每个信息块的大小。此时,DCI中包括的信息块的数量m 1与需要检测节能信息的终端设备的数量b 1相等,m 1=b 1,m 1个信息块与b 1个终端设备一一对应。即DCI中的指示信息指示的b 1个终端设备在该DCI包括的m 1个信息块中均具有对应的信息块。
具体的,假设DCI中包含的信息块的比特数的总和最多为Z 1,m 1个信息块中的每个信息块包括β 1个比特,该β 1满足如下关系:
Figure PCTCN2020090901-appb-000025
或者,
Figure PCTCN2020090901-appb-000026
其中,β max1为m 1个信息块中每个信息块所包含的比特数的最大值,Z 1、β 1均为正整数。
在此基础上,若通过上述方式得到的每个信息块中包括的比特数β 1小于β conf,β conf是指网络设备配置的指示每个终端设备的节能信息所需要的比特数,则可根据信息块中节能信息的指示方式进行如下处理:
情形一:如果信息块中的节能信息采用联合编码的方式指示,每个信息块中包括至少一个节能信息域中各个节能信息域的取值的组合对应的索引值。在这一情形中,若β 1小于β conf,每个信息块中包括的索引值的取值范围包括:各个节能信息域的取值的所有组合对应的索引值中索引值最小的前
Figure PCTCN2020090901-appb-000027
个索引值。
举例来说,终端设备的节能信息包括BWP ID(2比特)、跨时隙调度指示(1比特)、触发RS资源(2比特)、载波传输指示(单载波或多载波)(1比特)这四个节能信息域,而网络设备配置的用于指示每个终端设备的节能信息所需要的比特数β conf为3比特,那么这3比特的每个状态值的含义如表1所示:
表1:节能信息的每个状态值所包含节能信息域的状态值组合
Figure PCTCN2020090901-appb-000028
若计算得到的每个信息块包括的比特数β 1小于β conf,那么该信息块则指示节能信息比特的
Figure PCTCN2020090901-appb-000029
个状态值中取值较小的
Figure PCTCN2020090901-appb-000030
个状态值所对应的节能信息域的状态值组合。如果信息块包括的比特数β 1=2,那么信息块中的这2比特的每个状态值的含义如下表2所示,即取表1的前4行。
表2:信息块中每个状态值对应的节能信息域的状态值组合
Figure PCTCN2020090901-appb-000031
情形二:如果信息块中的节能信息采用独立的节能信息域的方式指示,每个信息块中包括独立的至少一个节能信息域。在这一情形中,若β 1小于β conf,每个信息块中包括的节能信息域可根据该至少一个节能信息域中各个节能信息域的优先级确定。因为优先级较低,而没有包含在信息块中的节能信息域可以使用“默认配置”。
例如,每个信息块中包括BWP ID(2比特)、跨时隙调度指示(1比特)、触发RS资源(2比特)、载波传输指示(单载波或多载波)(1比特)这四个节能信息域,四个节能信息域的优先级从高到低。若β 1=3,β conf=6,那么信息块则包括BWP ID和跨时隙调度指示这两个节能信息域。
在步骤S203和步骤S204中,终端设备可从网络设备接收该DCI,进而根据该DCI中的指示信息和该DCI的时域信息,在DCI包括的m 1个信息块中确定用于指示该终端设备的节能信息的信息块。终端设备可采用与网络设备类似的方式,确定m 1个信息块中有没有自己对应的信息块,若有对应的信息块,那么具体对应哪个信息块,此处不再赘述。
实施例二
下面将参考图7a至图7c,描述本申请实施例提供的另一种DCI的发送方法。
图7a为本申请实施例提供的另一种DCI的发送方法的流程示意图,该方法包括如下的步骤S701至步骤S704:
步骤S701、网络设备确定DCI,该DCI包括指示信息、Y 1个第一类型的信息块和Y 2个第二类型的信息块。该DCI可以为针对N个终端设备的节能信号,N为正整数。该N个终端设备可以属于一个终端设备组,即,该DCI为针对该终端设备组的节能信号。该节能信号可以称为唤醒信号,或者也可以具有其他名称,具体并不限定。
该指示信息用于指示N个终端设备中的每个终端设备是否被唤醒。在一种可能的设计中,该指示信息可以为第一比特序列,该第一比特序列也可以称为第一位图(bitmap)。该第一比特序列包括N个比特,每个比特与N个终端设备中的一个终端设备相对应,这里可 以理解为每个比特对应不同的终端设备,即N个比特与N个终端设备一一对应,每个比特用于指示对应的终端设备是否被唤醒。具体的,每个比特可具有第一状态值和第二状态值两种取值,当比特的取值为第一状态值时,可表示指示该比特对应的终端设备被唤醒,当比特的取值为第二状态值时,可表示指示该比特对应的终端设备不被唤醒。可选地,该第一状态值可以为1,第二状态值可以为0;或者,该第一状态值可以为非0值,第二状态值可以为0;或者,该第一状态值可以为0,第二状态值可以为1;或者,该第一状态值可以为0,第二状态值可以为非0值;或者,该第一状态值和第二状态值也可以为其它取值,本申请并不限定。在另一种可能的设计中,该指示信息也可以为第一比特序列对应的索引,用以间接地指示该第一比特序列。应理解的是,所述指示信息也可以称为UE指示域、节能指示域、唤醒指示域,或者也可以具有其他名称,本申请并不限定。这里描述的指示信息、信息块和节能信息等及其与终端设备之间的对应关系与实施例一中的相关术语的含义类似,因此不再赘述。
第一类型的信息块用于指示被唤醒的终端设备的节能信息,每个第一类型的信息块的大小为B 1个比特,第二类型的信息块用于指示不被唤醒的终端设备的节能信息,每个第二类型的信息块的大小为B 2个比特。这里,Y 1、Y 2、B 1和B 2均为正整数,此外,B 1不等于B 2,例如,B 1可以大于B 2。如此,被唤醒的终端设备的Y 1个第一类型的信息块共包括Y 1×B 1个比特,不被唤醒的终端设备的Y 2个第二类型的信息块共包括Y 2×B 2个比特。若指示信息为第一比特序列,那么该DCI中可共包括N+Y 1×B 1+Y 2×B 2个比特。
被唤醒的终端设备的节能信息可以包括下述项中的至少一个:被唤醒后的BWP、最小时隙偏移参数、触发非周期CSI的测量和上报、触发非周期SRS的发送、被唤醒后激活的搜索空间集(search space set)、被唤醒后做PDCCH检测(PDCCH monitoring)的载波。
不被唤醒的终端设备的节能信息可以包括下述项中的至少一个:跳过PDCCH检测的DRX周期数、在对应的ON duration是否发送周期/半静态调度(semi-persistent scheduling,SPS)的CSI报告或者周期/SPS的SRS的指示。
如图7b所示,在该DCI中,Y 1个第一类型的信息块可以是连续排列的,Y 2个第二类型的信息块也可以是连续排列的,指示信息位于Y 1个第一类型的信息块和Y 2个第二类型的信息块之前,CRC序列位于Y 1个第一类型的信息块和Y 2个第二类型的信息块之后。可选地,Y 1个第一类型的信息块可排列在Y 2个第二类型的信息块之前。或者,Y 2个第二类型的信息块也可以排列在Y 1个第一类型的信息块之前,本申请并不限定。这可以理解为,该DCI中包括两个信息块的指示域,分别为第一类型的信息块指示域和第二类型的信息块指示域,其中第一类型的信息块指示域包括Y 1个第一类型的信息块,每个第一类型的信息块的大小相同,第二类型的信息块指示域包括Y 2个第二类型的信息块,每个第二类型的信息块的大小相同。
值得注意的是,Y 1+Y 2≤N,也就是说,DCI中的信息块可能无法指示N个终端设备中的全部终端设备的节能信息。可能存在部分被唤醒的终端设备或者不被唤醒的终端设备在该DCI中没有对应的信息块,此时,指示为唤醒但不具有对应信息块的终端设备可按照默认的唤醒方式唤醒,指示为不唤醒但不具有对应信息块的终端设备可按照默认的不唤醒方式继续休眠(即不唤醒)。可选的,网络设备可通过向终端设备发送RRC消息,指示默认的唤醒方式和/或不唤醒方式,其中,默认的唤醒方式可包括指示被唤醒但不具有对应的信息块的终端设备的如下一项或多项信息:唤醒后的BWP、最小时隙偏移参数、触发非周 期CSI测量和上报、触发非周期SRS的发送、唤醒后激活的搜索空间集(search space set)、唤醒后做PDCCH检测(PDCCH monitoring)的载波。默认的不唤醒方式可包括指示不被唤醒且不具有对应信息块的终端设备的如下一项或多项信息:跳过PDCCH检测的DRX周期书、在对应的ON duration是否发送周期/SPS的CSI报告或者周期/SPS的SRS的指示。
具体的,在步骤S701中,网络设备可根据N个终端设备中需要唤醒的终端设备和不需要唤醒的终端设备,确定DCI中指示信息的取值。可以理解,这里确定指示信息,相当于确定第一比特序列。例如,可以将第一比特序列中需要唤醒的终端设备对应的比特设置为1,将不需要唤醒的终端设备对应的比特设置为0,得到该第一比特序列。
与实施例一中的方式类似,在指示信息为第一比特序列的情况下,网络设备可根据第一比特序列确定由被唤醒的终端设备对应的比特构成的第五比特序列、以及由不被唤醒的终端设备对应的比特构成的第六比特序列。
进而,网络设备可根据该DCI的时域信息,确定第二循环移位值和第三循环移位值,并根据第二循环移位值对第五比特序列进行循环移位,得到第七比特序列,根据第三循环移位值对第六比特序列进行循环移位,得到第八比特序列。所述DCI的时域信息可包括该DCI所在的帧的帧号和/或DCI所在的时隙的时隙号。
其中,第二循环移位值满足

进一步地,网络设备可将第七比特序列中第i个比特对应的终端设备的节能信息,映射到Y 1个第一类型的信息块中第i个信息块中,将第八比特序列中的第i个比特对应的终端设备的节能信息,映射到Y 2个第二类型的信息块中第i个信息块中,从而确定出该DCI中包括的Y 1个第一类型的信息块和Y 2个第二类型的信息块,即确定该DCI中Y 1个第一类型的信息块和Y 2个第二类型的信息块,与N个终端设备之间的对应关系。
图7c所示,针对被唤醒的终端设备对应的信息块,第F 2-1个被唤醒的终端设备被映射至信息块0,第F 2个被唤醒的终端设备被映射至信息块1,以此类推,如果在最低位的被唤醒的终端设备被映射至某个信息块后,Y 1个信息块中还存在未被映射的信息块,则从最高位的第0个被唤醒的终端设备开始继续映射。如果所有被唤醒的终端设备的数量小于Y 1,则在剩余的未被映射的信息块中补零。
类似地,针对不被唤醒的终端设备对应的信息块,第F 3-1个被唤醒的终端设备被映射至信息块0,第F 3个被唤醒的终端设备被映射至信息块1,以此类推,如果在最低位的被唤醒的终端设备被映射至某个信息块后,Y 2个信息块中还存在未被映射的信息块,则从最高位的第0个被唤醒的终端设备开始继续映射。如果所有被唤醒的终端设备的数量小于Y 2,则在剩余的未被映射的信息块中补零。
步骤S702、网络设备向上述N个终端设备发送该DCI。
步骤S703、终端设备从网络设备接收该DCI,该终端设备为上述N个终端设备之一。
步骤S704、终端设备根据DCI中的指示信息和该DCI的时域信息,在Y 1个第一类型的信息块或Y 2个第二类型的信息块中,确定用于指示该终端设备的节能信息的信息块。
终端设备可根据DCI中的指示信息,以及对应的比特在第一比特序列中的位置,确定是否被唤醒。若该终端设备在第一比特序列中对应的比特为第一状态值,终端设备可确定需要唤醒。进一步地,终端设备可采用与网络设备相同的方式确定第二循环移位值,并根据该第二循环移位值,从Y 1个第一类型的信息块中确定出自己对应的信息块,并按照对应的信息块中节能信息的指示唤醒,若Y 1个第一类型的信息块中不包括该终端设备对应的信息块,则该终端设备按照默认的唤醒方式唤醒。
若该终端设备在第一比特序列中对应的比特为第二状态值,终端设备可确定不需要唤醒。进一步地,终端设备可采用与网络设备相同的方式确定第三循环移位值,并根据该第三循环移位值,从Y 2个第二类型的信息块中确定出自己对应的信息块,并按照对应信息块中节能信息的指示继续休眠(即不唤醒),若Y 2个第二类型的信息块中不包括该终端设备对应的信息块,则该终端设备按照默认的不唤醒方式继续休眠。
本申请实施例中,网络设备还可向终端设备发送RRC消息,在该RRC消息中指示该终端设备对应的比特在第一比特序列中的位置,以及该DCI中包括的第一类型的信息块的数量Y 1和第二类型的信息块的数量Y 2。以便该终端设备确定是否被唤醒,以及第二循环移位值和/或第三循环移位值。
可选地,该RRC消息可用于指示为该终端设备配置的如下一项或多项信息:
●检测该DCI的时频资源;
●用于加扰该DCI的CRC的无线网络临时标识(radio network temporary indication,RNTI),该RNTI例如可以是功率节省(power saving,PS)-RNTI;
●该DCI的指示信息中指示的终端设备的数量N、该DCI包括的第一类型的信息块的数量Y 1、每个第一类型的信息块的大小B 1、该DCI包括的第二类型的信息块的数量Y 2、每个第二类型的信息块的大小B 2
●该终端设备对应的比特在第一比特序列中的位置;
●被唤醒的终端设备的节能信息指示的一项或多项参数;
●不被唤醒的终端设备的节能信息指示的一项或多项参数。
由上述内容可知,采用这种DCI的发送方法,网络设备可分别对被唤醒的终端设备、以及不被唤醒的终端设备进行随机化,如此,无论各个终端设备被唤醒或不被唤醒,都有公平的机会获得节能信息,从而充分发挥节能信号的节能作用。
实施例三
下面将参考图8a至图8c,描述本申请实施例提供的又一种DCI的发送方法。
图8a为本申请实施例提供的又一种DCI的发送方法的流程示意图,该方法包括如下的步骤S801至步骤S804:
步骤S801、网络设备确定DCI,该DCI包括指示信息、Y 1个第一类型的信息块和Y 2个第二类型的信息块。
具体的,在步骤S801中,网络设备可根据N个终端设备中需要唤醒的终端设备和不需要唤醒的终端设备,确定DCI中指示信息的取值。可以理解,这里确定指示信息,相当于确定第一比特序列。例如,可以将第一比特序列中需要唤醒的终端设备对应的比特设置 为1,将不需要唤醒的终端设备对应的比特设置为0,得到该第一比特序列。
进而,网络设备可根据该DCI的时域信息,确定第四循环移位值,根据该第四循环移位值对第一比特序列进行循环移位,得到第九比特序列。该第四循环移位值满足
Figure PCTCN2020090901-appb-000036
其中,F 4为第四循环移位值,SFN为DCI所在的帧的系统帧号(system frame number,SFN),
Figure PCTCN2020090901-appb-000037
为DCI所在的时隙的时隙号,a和b为协议预定义的整数,且不能同时为0。
进一步地,网络设备可将第九比特序列中的第i个比特对应的终端设备的节能信息,映射到该DCI中的第i个信息块中。若该第i个比特的取值为第一状态值,则表示对应的终端设备需要被唤醒,且该DCI中的第i个信息块为第一类型的信息块,该信息块的大小为B 1。若该第i个比特的取值为第二状态值,则表示对应的终端设备不需要被唤醒,且该DCI中的第i个信息块为第二类型的信息块,该信息块的大小为B 2
需要注意的是,本实施例与实施例二的差别在于,该DC中所有信息块加起来总共为Z个比特,Y 1和Y 2的数量不固定。如图8b所示,Y1个第一类型的信息块可以不连续排列,同样Y2个第二类型的信息块也可以不连续排列,且各个终端设备对应的信息块的顺序,与各个终端设备对应的比特在第九比特序列中的顺序保持一致。本申请实施例中,同样满足Y 1+Y 2≤N。也就是说,由于DCI中信息块的总比特数固定,仍会存在指示被唤醒或不被唤醒的终端设备在该DCI中不存在对应的信息块的情况,即无论某个终端设备指示被唤醒或不被唤醒,只要其在进行随机化后的第九比特序列中的顺序靠后,则该DCI中有可能不存在该终端设备对应的信息块。
如图8c所示,第F 4-1个终端设备被映射到信息块0,如果是唤醒的终端设备,则信息块0的比特数为B 1,如果是不被唤醒的终端设备,则信息块0的比特数为B 2;第F 4个终端设备被映射到信息块1,以此类推,如果在最低位的终端设备被映射至某个信息块之后,已映射的信息块的总比特数还小于Z,则从最高位的第0个终端设备开始继续映射。如果所有终端设备都被映射到信息块之后,已映射的信息块的总比特数仍小于Z,则在该字域剩余的位置补零。
步骤S802、网络设备向上述N个终端设备发送该DCI。
步骤S803、终端设备从网络设备接收该DCI,该终端设备为上述N个终端设备之一。
步骤S804、终端设备根据DCI中的指示信息和该DCI的时域信息,确定用于指示该终端设备的节能信息的信息块。
终端设备可根据DCI中的指示信息,以及对应的比特在第一比特序列中的位置,确定是否被唤醒。若该终端设备在第一比特序列中对应的比特为第一状态值,终端设备可确定需要唤醒。进一步地,终端设备可采用与网络设备相同的方式确定第四循环移位值,利用第四循环移位值对第一比特序列进行循环移位,然后根据对应的比特在第九比特序列中的位置,确定该DCI中是否存在自己对应的信息块。若存在,则按照对应的信息块中节能信息的指示唤醒,若不存在,则按照默认的唤醒方式唤醒。
若该终端设备在第一比特序列中对应的比特为第二状态值,终端设备可确定不需要唤醒。进一步地,终端设备可采用与网络设备相同的方式确定第四循环移位值,利用该第四循环移位值对第一比特序列进行循环移位,然后根据对应的比特在第九比特序列中的位置,确定该DCI中是否存在自己对应的信息块。若存在,则按照对应的信息块中节能信息的指示继续休眠,若不存在,则按照默认的不唤醒方式继续休眠。
由上述内容可知,采用这种DCI的发送方法,网络设备可对被唤醒的终端设备、以及不被唤醒的终端设备一起进行随机化,并按照统一的顺序映射到信息块,如此,各个终端设备可有公平的机会获得节能信息,从而充分发挥节能信号的节能作用。
