Description

一种控制信息传输方法、相关装置及计算机存储介质
本申请要求在2017年05月04日提交中国专利局、申请号为201710309765.7、发明名称为“一种控制信息传输方法、相关装置及计算机存储介质”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信领域,尤其涉及一种控制信息传输方法、相关装置及计算机存储介质。
背景技术
移动通信系统中,网络设备在终端设备对应的下行控制信道所在的时频资源上发送控制信息和参考信号,现有技术中,参考信号的时频资源位置预先定义,终端设备根据参考信号的时频资源位置,接收参考信号,并根据接收到的参考信号进行信道估计,之后根据信道估计结果对控制信息进行解调。
一种现有技术中,将参考信号分布在整个控制信息所在的时频资源区域,图1示例性示出了现有技术中将参考信号分布在控制信道所在的时频资源区域的结构示意图,如图1所示,横坐标表示时域,纵坐标表示频域,在频域方向上包括第一物理资源块101、第二物理资源块102和第三物理资源块103,每个物理资源块在频域上占用连续的12个子载波,在时域上可占用多个连续的符号,比如7个连续的符号。若将第一个符号上的子载波用于承载控制信道的信息,则无论第一个符号上对应的一个物理资源块中是否承载了控制信息,则该物理资源块中均承载参考信号。如图1所示,第二物理资源块102中没有承载控制信息,但是仍然在第二物理资源块上发送参考信号。由于该技术中参考信号的密度太高,因此导致资源的浪费。
为了避免图1所示的现有技术中的资源浪费的问题,图1a示例性示出了另一种现有技术中将参考信号分布在控制信道所在的时频资源区域的结构示意图,如图1a所示,第二物理资源块102中没有承载控制信息,因此在第二物理资源块上未发送参考信号。但是由于该技术中一个物理资源块中的参考信号的数量过于少,因此在针对一个物理资源块中的参考信号进行信道估计时,信道估计的结果准确性下降。

可选的,控制信道包括的物理资源块在频域上不连续,例如,若位图为{0 0 0 0 1 0 1 0 1 0 1 0 0 0 0 0},系统带宽内,第5个,第7个,第9个,第11个连续的6个物理资源块用于控制信道的传输,所述控制信道在频域上包括离散的24个物理资源块。
本发明实施例中控制信道频域信息的配置不限于上述举例,上述示例仅是为了理解本发明所举的例子,只要配置信息中包括频域资源大小,或频域资源位置的配置信息都属于本发明要保护的范围,在此不再赘述。

或者,配置信息中包括了控制信道在一个给定时域周期内所在的时隙的位置;例如,预定义或可配的一个周期包括10个时隙,通过位图的方式指示控制信道所在的时隙位置,其中位图包括的比特长度等于一个周期内包括的时隙的数量;若位图为{1 0 0 0 0 1 0 0 0 0},则在时域上第一个和第六个时隙包括所述控制信道。
除位图的指示方法外,还可以预定义时域出现的位置为{第一个时隙,第六个时隙},{第三个时隙,第七个时隙},{第一个时隙};标识符可以为一个比特序列,例如,{00}对应控制信道时域出现的位置为{第一个时隙,第六个时隙},{01}对应控制信道时域出现的位置为{第三个时隙,第七个时隙},{10}对应控制信道时域出现的位置为{第一个时隙}。时域的指示方法这里不做限定,可以是位图的方法,或是标识符指示预定义的时域位置都属于本发明保护范围。

例如,用于指示至少一个资源单元集合的指示信息可以是具体指示出一个资源单元集合所占用的符号和占用的子载波,典型值可以为,在时域包括的符号为1个,2个或3个符号中的一个;在频域包括12个,24个,48个或72个子载波中的一个。

天线端口数量可以为1或2,若天线端口数量为1,则资源单元集合内每个资源单元组中的参考信号位置对应图4j中的资源单元集合类型的{0}。若天线端口数为2,则资源单元集合内每个资源单元组中的参考信号位置对应图4j中的资源单元集合类型的{7}。
本发明实施例中指示发送参考信号的资源单元的位置信息不限于上述举例,上述示例中通过天线端口数量进行指示仅是为了理解本发明所举的例子,只要配置信息中包括指示资源单元集合内用于传输参考信号的资源单元的数量和或资源单元的位置都属于本发明要保护的范围,在此不再赘述。

具体实施中,针对业务场景不同,控制信道在时域和频域变化不同,资源单元集合中包括的资源单元组在时域和频域的数量也会不同,因此,还可对资源单元集合中资源单元组的时频资源大小进行设计,以便进一步提高控制信道的覆盖能力。

所述编号连续的两个资源单元集合,可为占频域子载波相同且时域相邻的两个资源单元集合,或者,可为占时域符号相同相同且在频域子载波编号相邻的两个资源单元集合。
图4i示例性示出了本申请实施例提供的一种资源单元的结构示意图,如图4h所示,在时域上,每个资源单元占用一个符号,用字母l表示,则在时域坐标上,第一个符号表示为l,则第二个符号表示为l+1;在频域坐标上,第一个子载波的编号表示为k,则第二个子载波的编号表示为k+1;依次类推。若一个资源单元在占用了符号l,在频域上占用了k至k+11个子载波,则该资源单元组的索引可以表示为该资源单元组符号最小或子载波编号最小的资源单元的符号和子载波标识,比如该资源单元组的索引可以表示为(k,l)。
可选地,在资源单元组集合内,资源单元组中包括的资源单元的符号可以定义为:

根据资源单元组集合的定义,控制信道内可包括多个资源单元组集合,多个资源单元组集合编号依次为0,…,N GREG-1,其中,GREG英文可表示为Group of resource elements group,中文可称为资源元素组,N GREG表示控制信道内包括多个资源单元组集合的数量。其中,令u作为资源单元集合的编号,u∈{0,…,N GREG-1},则第u个资源单元集合在频域上对应的编号最小的子载波为k 0=u·M·N RB sc。或者,根据编号u和N,确定资源单元组在频域上对应的物理资源块的编号n RB;其中,n RB满足n RB mod M=0;或者n RB=u·M;或者n RB=u·M+A,其中,A可以为一个随机变量。Mod为取模运算。
本申请实施例,在频域上,物理资源块的编号与资源单元组的编号相同,因此本申请实施例中所描述的物理资源块在频域上的编号和资源单元组在频域上的编号可理解为同一个值。
可选地,配置信息中还可包括至少一个资源单元集合中的每个资源单元集合中包括的每个资源单元组在时域和频域占用资源的指示信息。如此,当一个资源单元集合中包括不同结构形式的资源单元组时,可以分别指示。
可选地本申请实施例中的资源单元集合可以包括相同结构的一个或多个资源单元组,资源单元集合中包括的两个资源单元组的结构也可不同。图4j示例性示出了本申请实施例提供的几种资源单元集合的结构示意图,如图4j所示,资源单元集合的类型信息为0的资源单元集合中包括一个资源单元组,该资源单元组中用10个资源单元承载控制信息,用其余两个资源单元承载参考信号。如图4j所示,资源单元集合的类型信息为1的资源单元集合中包括两个资源单元组,两个资源单元组在频域方向连续排布,该两个资源单元组中的每个资源单元组中用10个资源单元承载控制信息,用其余两个资源单元承载参考信号。如图4j所示,资源单元集合的类型信息为6的资源单元集合中包括三个资源单元组,三个资源单元组在时域方向连续排布,其中,最上面和最下面的两个资源单元组中的每个资源单元组中用10个资源单元承载控制信息,用其余两个资源单元承载参考信号,中间的资源单元组中的资源单元全部用于承载控制信息。其余资源单元集合的类型与上述内容类似,在此不再一一赘述。

可选地,在图4j中的资源单元集合的类型信息1、对应PDCCH格式为PDCCH格式0和PDCCH格式1。而在图4j中的资源单元集合的类型信息3,对应PDCCH格式为PDCCH格式2和PDCCH格式3。
因此,在本方法中,所述PDCCH格式对应控制信道搜索空间的不同聚合等级,例如表1中,PDCCH格式0对应聚合等级1,PDCCH格式1对应聚合等级2,PDCCH格式2对应聚合等级4,PDCCH格式3对应聚合等级8。而不同的资源单元集合,可以对应一个或多个PDCCH格式;图4j中的资源单元集合的类型不同对应的PDCCH格式可以相同或不同。或者,图4j中的资源单元集合的类型不同对应的聚合等级可以相同或不同。

网络设备确定完上述配置信息之后,接着当网络设备确定出控制信息时,依据配置信息将控制信息映射至资源单元集合中。通常来说,控制信息为下行控制信息。下行控制信息为一个或多个。每个控制信息都是一个比特序列。将多个控制信息的比特序列依次排布,并进行加扰和调制,之后得到需要发送的控制信息对应的E个调制符号。该E个调制符号是按照之前控制信息的比特序列的排布顺序进行排序的。
可选地,所述网络设备根据所述配置信息将控制信息映射到所述至少一个资源单元集合中的一个或多个资源单元集合上,包括:所述网络设备根据所述配置信息将控制信息和参考信号映射到所述至少一个资源单元集合中的一个或多个资源单元集合上;其中,包括所述控制信息的资源单元集合中的一个或多个资源单元上映射有参考信号。相应地,所述终端设备根据所述配置信息检测控制信道,获取映射到所述至少一个资源单元集合中的一个或多个资源单元集合上的控制信息,包括:所述终端设备根据所述配置信息检测控制信道,获取映射到所述至少一个资源单元集合中的一个或多个资源单元集合上的控制信息,以及获取映射在包括所述控制信息的资源单元集合中的一个或多个资源单元上的参考信号。如此,可以避免不发送控制信息的资源单元集合中也承载控制信号,进而降低了资源的浪费率。
可选地,网络设备根据配置信息将终端的控制信息映射到至少一个资源单元集合,包括:网络设备将控制信息进行调制,得到E个调制符号;其中,E为大于等于5的整数;网络设备将E/F个调制符号组和参考信号映射到至少一个资源单元集合中。
也就是说,本申请实施例中将控制信息映射到资源单元集合上时,是以F个调制符号为一组的粒度进行映射的,由于一个资源单元集合可包括一个或多个资源单元组,因此可以联合一个资源单元集合中包括的所有资源单元组中的参考信号进行联合信道估计,从而提高信道估计的准确度。
本申请实施例中提供几种可选地实施方案,一种可选地实施方案中,将E/F个调制符号组进行交织,比如进行重排和/或移位,从而实现将控制信息以F个调制符号为一组的粒度进行打乱的目的。具体来说,网络设备以E个调制符号中F个调制符号为一个调制符号组,对E个调制符号对应的E/F个调制符号组进行交织;其中,F为小于等于E,且大于4 的整数;网络设备将进行交织后的E/F个调制符号组和参考信号映射到至少一个资源单元集合中;其中,一个资源单元集合映射一个调制符号组,且若一个资源单元集合映射有控制信息,则该资源单元集合映射有参考信号;若一个资源单元集合未映射控制信息,则该资源单元集合未映射参考信号。如此,将一个控制信息映射在多个资源单元集合上时,可以使该控制信息在频域和/或时域上分布更广,从而得到更大的频域分集增益和时域分集增益。
进一步,本申请实施例中将E/F个调制符号组和参考信号映射到多个资源单元集合中时,可以按时域优先或频域优先方式进行排布。举个例子,给定资源单元集合和资源单元组的编号,终端设备需要将E/F个调制符号组和参考信号映射到6个资源单元集合中,在子载波编号为1的频域上依次包括符号为1的资源单元集合1、符号为2的资源单元集合2以及符号为3的资源单元集合3。在子载波编号为2的频域上依次包括符号为1的资源单元集合4、符号为2的资源单元集合5以及符号为3的资源单元集合6。若为时域优先,则将E/F个调制符号组和参考信号映射到6个资源单元集合中的次序依次为:资源单元集合1、资源单元集合2、资源单元集合3、资源单元集合4、资源单元集合5和资源单元集合6;若为频域优先,则将E/F个调制符号组和参考信号映射到6个资源单元集合中的次序依次为:资源单元集合1、资源单元集合4、资源单元集合2、资源单元集合5、资源单元集合3和资源单元集合6。
进一步,本申请实施例中将E/F个调制符号组和参考信号映射到多个资源单元集合中时,可以按时域优先或频域优先方式进行排布。举个例子,比如终端设备需要将E/F个调制符号组和参考信号映射到6个资源单元集合中,在子载波编号为1的频域上依次包括符号为1的资源单元集合1、符号为2的资源单元集合2以及符号为3的资源单元集合3。在子载波编号为2的频域上依次包括符号为1的资源单元集合4、符号为2的资源单元集合5以及符号为3的资源单元集合6。若为时域优先,则将E/F个调制符号组和参考信号映射到6个资源单元集合中的次序依次为:资源单元集合1、、资源单元集合2、资源单元集合3、资源单元集合4、资源单元集合5和资源单元集合6;若为频域优先,则将E/F个调制符号组和参考信号映射到6个资源单元集合中的次序依次为:资源单元集合1、资源单元集合4、资源单元集合2、资源单元集合5、资源单元集合3和资源单元集合6。
另一种可选地实施方案中,将资源单元集合的编号或者索引进行交织,从而实现将控制信息以F个调制符号为一组的粒度进行打乱的目的。图4k示例性示出了本申请实施例提供的一种将控制信息的比特序列进行映射的流程示意图。每个终端设备对应一个或多个CCE,其中每个CCE可包一个或多个资源单元集合,如图4k所示,一个CCE包括三个资源单元集合。可选地,本申请实施例中在图4k中将47个资源单元组划分为24个资源单元集合,本申请实施例中将24个资源单元集合的编号进行交织,比如进行重排和/或移位,如图4k所示将24个资源单元集合的编号进行交织后资源单元集合的编号相互都会被打乱,之后将连续的三个资源单元集合编号对应的资源单元组上映射一个CCE对应的控制信息。如此,将一个控制信息映射在多个资源单元集合上时,可以使该控制信息在频域和/或时域上分布更广,从而得到更大的频域分集增益和时域分集增益。
第三种可选地实施方案中,将E/F个调制符号组进行交织,并且将资源单元集合的编号或者索引进行交织,从而实现将控制信息以F个调制符号为一组的粒度进行打乱的目的。
通过上述方案,本申请实施例中会得到E/F个调制符号组中的每个符号组与资源单元 集合的对应关系,一个调制符号组对应一个资源单元集合。
可选地,网络设备将进行交织后的N/K个调制符号组和参考信号映射到至少一个资源单元集合中,包括:网络设备根据时域优先或频域优先,将进行交织后的N/K个调制符号组和参考信号映射到至少一个资源单元集合中。时域优先的的方式中,可优先在时域方向上映射控制信息和/或参考信号。频域优先的的方式中,可优先在频域方向上映射控制信息和/或参考信号。
可选地,配置信息还包括以下内容中的任一项或任多项:控制信息的映射方式指示信息;其中,映射方式包括时域优先或频域优先。
一种可选地实施方式中,网络设备根据配置信息将控制信息映射到至少一个资源单元集合中的一个或多个资源单元集合上,包括网络设备根据资源单元集合的索引进行映射。
相应地,若控制信息是网络设备根据资源单元集合的索引进行的映射,则:终端设备根据配置信息检测控制信道,获取映射到至少一个资源单元集合中的一个或多个资源单元集合上的控制信息,包括:终端设备根据配置信息,以及资源单元集合的索引,对终端设备的控制信道进行检测,得到映射到至少一个资源单元集合中的一个或多个资源单元集合上的控制信息。
比如,图4i所示的为一个资源单元集合时,仅根据资源单元集合的索引进行的映射。若为时域优先方式,则进行映射的资源单元的序号依次为(k,l)、(k,l+1)、(k+1,l)、(k+1,l+1)、(k+2,l)、(k+2,l+1)、(k+3,l)、(k+3,l+1)、(k+4,l)、(k+4,l+1)、(k+5,l)、(k+5,l+1)、(k+6,l)、(k+6,l+1)、(k+7,l)、(k+7,l+1)、(k+8,l)、(k+8,l+1)、(k+9,l)、(k+9,l+1)、(k+10,l)、(k+10,l+1)、(k+11,l)、(k+11,l+1)。若为频域优先方式,则进行映射的资源单元的序号依次为(k,l)、(k+1,l)、(k+2,l)、(k+3,l)、(k+4,l)、(k+5,l)、(k+6,l)、(k+7,l)、(k+8,l)、(k+9,l)、(k+10,l)、(k+11,l)、(k,l+1)、(k+1,l+1)、(k+2,l+1)、(k+3,l+1)、(k+4,l+1)、(k+5,l+1)、(k+6,l+1)、(k+7,l+1)、(k+8,l+1)、(k+9,l+1)、(k+10,l+1)、(k+11,l+1)。
另一种可选地实施方式中,网络设备根据配置信息将控制信息映射到至少一个资源单元集合中的一个或多个资源单元集合上,包括网络设备根据资源单元集合包括的资源单元组的索引进行映射。
相应地,若控制信息是网络设备根据资源单元集合包括的资源单元组的索引进行的映射,则:终端设备根据配置信息检测控制信道,获取映射到至少一个资源单元集合中的一个或多个资源单元集合上的控制信息,包括:终端设备根据配置信息,以及资源单元集合包括的资源单元组的索引,对终端设备的控制信道进行检测,得到映射到至少一个资源单元集合中的一个或多个资源单元集合上的控制信息。
比如,图4i所示的为一个资源单元集合,该集合包括两个资源单元组,第一个资源单元组包括符号为l,子载波编号为k至k+11的12个子载波,第二个资源单元组包括符号为2,子载波编号为k至k+11的12个子载波。
比如,图4i所示的为一个资源单元集合时,仅根据资源单元集合的索引进行的映射。若为时域优先方式,则先映射符号1的资源单元组,之后再映射符号2的资源单元组。若为频域优先方式,且若图4i的资源单元集合中在k+11之上还包括第三个资源单元组,第三个资源单元组包括符号为1,子载波编号为k+12至k+23的12个子载波。则先映射符号1上的第一个资源单元组,再映射至符号1上的第三个资源单元组,之后再映射至符号2 上的资源单元组。可选地,控制信息在资源单元组内如何映射,该实施方案中不限定,可以频域优先也可时域优先。
第三种可选地实施方式中,网络设备根据配置信息将控制信息映射到至少一个资源单元集合中的一个或多个资源单元集合上,包括:网络设备根据资源单元集合的索引和资源单元集合包括的资源单元组的索引进行映射。
相应地,若控制信息是网络设备根据资源单元集合的索引和资源单元集合包括的资源单元组的索引进行的映射,则:终端设备根据配置信息检测控制信道,获取映射到至少一个资源单元集合中的一个或多个资源单元集合上的控制信息,包括:终端设备根据配置信息,以及资源单元集合的索引和资源单元集合包括的资源单元组的索引,对终端设备的控制信道进行检测,得到映射到至少一个资源单元集合中的一个或多个资源单元集合上的控制信息。
比如,图4i所示的为一个资源单元集合,该集合包括两个资源单元组,第一个资源单元组包括符号为l,子载波编号为k至k+11的12个子载波,第二个资源单元组包括符号为2,子载波编号为k至k+11的12个子载波。
比如,图4i所示的为一个资源单元集合时,仅根据资源单元集合的索引进行的映射。若为时域优先方式,则先映射符号1的资源单元组,之后再映射符号2的资源单元组。若为频域优先方式,且若图4i的资源单元集合中在k+11之上还包括第三个资源单元组,第三个资源单元组包括符号为1,子载波编号为k+12至k+23的12个子载波。则先映射符号1上的第一个资源单元组,再映射至符号1上的第三个资源单元组,之后再映射至符号2上的资源单元组。
进一步,若为时域优先,则控制信息在资源单元组内仍旧按时域优先的方式映射;若为频域优先,则控制信息在资源单元组内仍旧按频域优先的方式映射。
比如在图4i中,若为时域优先方式,则对于第一个资源单元组中进行映射的资源单元的序号依次为(k,l)、(k+1,l)、(k+2,l)、(k+3,l)、(k+4,l)、(k+5,l)、(k+6,l)、(k+7,l)、(k+8,l)、(k+9,l)、(k+10,l)和(k+11,l)。
进一步,本申请实施例中,可选地配置信息中还包括至少一个资源单元集合中映射有控制信息的资源单元集合中控制信息和参考信号之间的功率比值。如此,可以根据控制信息和参考信号之间的功率比值更加准确的进行信道估计。
举个例子,若指示资源单元集合中控制信息和参考信号之间的功率比值为1,则终端设备可根据参考信号所在资源单元和承载控制信息的资源单元的功率比值进行信道估计;若指示资源单元集合中控制信息和参考信号之间的功率比值为2,则终端设备根据资源单元集合中控制信息和参考信号之间的功率比值调整信道估计的参数,之后进行信道估计。
图4l示例性示出了本申请实施例提供的一种单天线端口的参考信号和控制信息在一个资源单元组上的映射结构示意图,如图4l所示,一个资源单元组中可用两个资源单元承载参考信号。若参考信号功率的指示信息指示功率比值为1或2时,用于传输控制信息的资源单元的数量和位置不改变。
