Description

信号资源配置方法、终端及接入网设备 技术领域
本发明涉及通信领域,具体涉及信号资源配置方法、终端及接入网设备。
背景技术
长期演进(Long Term Evolution,LTE)是由第三代合作伙伴计划(The 3rd Generation Partnership Project,3GPP)组织制定的通用移动通信系统(Universal Mobile Telecommunications System,UMTS)技术标准的长期演进,使得陆地移动通信网络的新技术研究与商用能够平滑的进行。在LTE的第13个版本中,引入了全维度多天线(Full Dimensional MIMO,FD-MIMO)技术,即在接入网设备侧借助2维天线阵列,同时进行水平维度和垂直维度波束赋型,并据此进行相应的预编号码本增强及反馈流程增强等,可以显著地提升小区容量。第13版本的FD-MIMO最多支持16个天线阵元,为了测量这16个天线阵元的信道特征,设计了16个端口的信道状态信息的参考信号(Channel State Information Reference Signal,CSI-RS)。而到了第14版本,目前正讨论将阵元数升级到{20,24,28,32}个。因此,对{20,24,28,32}阵元的信道测量,需要{20,24,28,32}端口的CSI-RS来支持。
在第13版本的FD-MIMO中,16天线端口的CSI-RS是通过将两组8天线端口的CSI-RS聚合来得到,而12天线端口的CSI-RS是通过将三组4天线端口的CSI-RS聚合来得到,同时,为了保证在每个OFDM符号上的CSI-RS的功率,16天线端口和12天线端口使用了正交码进行多个端口参考信号在相同时频资源组上的码分复用(Code Divide Multiplexing,CDM),来进行功率提升。现有的CSI-RS资源技术方案中为重新定义用于聚合出32端口CSI-RS的8端口CSI-RS,对于32端口,采用4组新定义的8端口CSI-RS进行聚合,在新定义的8端口CSI-RS上,采用CDM-8进行码分复用,从而实现功率的有效利用。在32端口的基础上,在每个CDM分组里,去掉3组CDM不用得到20端口的;在32端口的基础上,在每个CDM分组里,去掉2组CDM不 用得到24端口的;在32端口的基础上,在每个CDM分组里,去掉1组CDM不用得到28端口的。即20、24和28端口对CSI-RS资源粒子的占用,与32端口的完全一致。
但是,重新定义用于聚合的8端口CSI-RS,虽然可以采用CDM-8进行码分复用以实现功率的有效利用,但这样对原有的标准影响较大;另外,在端口少于32的情况下,例如20端口,CSI-RS资源粒子的占用与32端口一致,而实际上在每个CDM分组里,是去掉了3组CDM不用来得到20端口,因此,导致CSI-RS的无效资源的消耗增大。
发明内容
本发明提供信号资源配置方法、终端及接入网设备,用于降低对现有标准的影响,节约CSI-RS的资源。
本发明第一方面提供一种信号资源配置方法,包括:
接入网设备向终端设备发送一个2N端口的CSI-RS资源序号,所述2N端口的CSI-RS资源序号用于通知所述终端设备处于两个相邻PRB中的N端口CSI-RS资源,N为正整数。
接入网设备向终端设备发送一个2N端口的CSI-RS资源序号,使得终端设备可以确定处于两个相邻物理资源块(Physical Resource Block,PRB)中的N端口CSI-RS资源,由于2N端口CSI-RS资源是由不同PRB中的N端口CSI-RS子资源聚合得到的,那么在现有技术中,24和32端口CSI-RS资源使用8端口CSI-RS资源聚合得到的情况下,利用多个8端口资源序号也能对20和28端口CSI-RS资源进行配置,从而可以减小信令开销,对现有标准的影响也较小;而与现有技术相比,在20端口的情况下,进行CDM-8配置时,无需在每个CDM分组里,去掉3组CDM;而在28端口的情况下,无需在每个CDM分组里,去掉1组CDM,因此本方案在4(2K+1)端口时,例如20端口或28端口,不会存在资源浪费。
结合本发明第一方面,本发明第一方面第一实施方式中,
所述2N端口的CSI-RS资源序号用于指示一个处于两个不同PRB中的2N端 口CSI-RS资源;
所述2N端口CSI-RS资源为第一PRB中的第一N端口CSI-RS子资源与第二PRB中的第二N端口CSI-RS子资源;或,所述2N端口CSI-RS资源为为第一PRB中的第一2N端口CSI-RS子资源的一半与所述第二PRB中的第二2N端口CSI-RS子资源的一半。
假设两个PRB内的N端口CSI-RS子资源为4端口的,第一PRB中的第一4端口CSI-RS子资源与第二PRB中的第二4端口CSI-RS子资源进行聚合,得到8端口CSI-RS资源,第一4端口CSI-RS子资源与第二4端口CSI-RS子资源的时频域位置相同;第一PRB中的第一8端口CSI-RS子资源的一半与第二PRB中的第二8端口CSI-RS子资源的一半进行聚合,得到8端口CSI-RS资源,第一8端口CSI-RS子资源的一半与第二8端口CSI-RS子资源的一半的时频域位置相同,且所截取一半的位置也相同,这样做的好处是,对于低于第14版本的终端设备,可以视作静默的CSI-RS资源,从而不会增加终端设备的额外导频开销。
结合本发明第一方面第一实施方式,本发明第一方面第二实施方式中,所述信号资源配置方法还包括:
所述接入网设备配置多个2N端口CSI-RS资源得到4(2K+1)端口CSI-RS资源,所述多个2N端口CSI-RS资源包括第一CSI-RS资源和第二CSI-RS资源,所述第一CSI-RS资源为处于同一PRB中的2N端口CSI-RS资源,所述第二CSI-RS资源为处于两个不同PRB中的2N端口CSI-RS资源,K为正整数;
所述接入网设备将所述多个2N端口CSI-RS资源的资源序号发送至所述终端设备。
接入网设备在发送2N端口的CSI-RS资源序号之前,需要对2N端口的CSI-RS资源进行配置,以聚合得到4(2K+1)端口CSI-RS资源,而2N端口CSI-RS资源包括第一CSI-RS资源和第二CSI-RS资源,第一CSI-RS资源为处于同一PRB中的2N端口CSI-RS资源第一种实现方式如图8所示,对于一个20端口的CSI-RS资源,PRB1中的4端口CSI-RS资源{31,32}和{33,34},与PRB2中的4端口CSI-RS资源{31,32}和{33,34}聚合成为8端口CSI-RS资源,第二CSI-RS资源为处于两个不同PRB中的2N端口CSI-RS资源,K为正整数,在得到4(2K+1)端 口CSI-RS资源之后,接入网设备将多个2N端口CSI-RS资源的资源序号发送给终端设备,使得终端设备根据多个2N端口CSI-RS资源的资源序号能够确定4(2K+1)端口CSI-RS资源。
结合本发明第一方面第二实施方式,本发明第一方面第三实施方式中,所述接入网设备配置多个2N端口CSI-RS资源得到4(2K+1)端口CSI-RS资源之后,还包括:

所述接入网设备对所述第一CSI-RS资源对应的端口进行编号;
所述接入网设备对所述第二CSI-RS资源对应的端口进行编号。
接入网设备按照预先设置的编号规则,需要优先对处于同一PRB中的2N端口CSI-RS资源(即第一CSI-RS资源)对应的端口进行编号,再对处于两个不同PRB中的2N端口CSI-RS资源(即第二CSI-RS资源)对应的端口进行编号,这样做的好处是可以保证较好的前向兼容特性,而且预先设置的编号规则是接入网设备和终端设备所共知的。
结合本发明第一方面第二实施方式,本发明第一方面第四实施方式中,所述接入网设备配置多个2N端口CSI-RS资源得到4(2K+1)端口CSI-RS资源之后,还包括:

所述接入网设备对所述第一CSI-RS资源配置2N路CDM;
所述接入网设备对所述第二CSI-RS资源配置N路CDM,并增加3dB发射功率。
由于第一CSI-RS资源为处于同一PRB中的2N端口CSI-RS资源,因此配置2N路CDM;而对于第二CSI-RS资源为处于两个不同PRB中的2N端口CSI-RS资源,为了节省CDM资源,配置N路CDM即可,并且进行3dB功率放大处理,这样可以保证所有端口上的功率一致性。为了保证CDM跨越资源粒子(RE)的信道状态一致性,需要尽可能减少频域跨度,最大间隔不超过6个子载波(即6个RE)。
本发明第二方面提供一种信号资源配置方法,包括:
终端设备接收接入网设备发送的2N端口的CSI-RS资源序号;
所述终端设备根据所述2N端口的CSI-RS资源序号确定处于两个相邻物理资源块PRB中的N端口CSI-RS资源,N为正整数。
终端设备接收接入网设备发送的2N端口的CSI-RS资源序号,由于2N端口的CSI-RS资源序号用于指示两个相邻PRB中的N端口CSI-RS资源,因此终端设备根据2N端口的CSI-RS资源序号确定可以确定处于两个相邻PRB中N端口CSI-RS资源,由于2N端口CSI-RS资源是由不同PRB中的N端口CSI-RS子资源聚合得到的,那么在现有技术8端口CSI-RS资源和8路CDM(CDM-4)的情况下,利用1一个8端口资源序号就能对8端口CSI-RS资源进行排序,无需重新定义,对现有标准的影响较小;而与现有技术相比,在20端口的情况下,进行CDM-8配置时,无需在每个CDM分组里,去掉3组CDM;而在28端口的情况下,无需在每个CDM分组里,去掉1组CDM,因此本方案在4(2K+1)端口时,例如20端口或28端口,不会存在资源浪费。

所述2N端口CSI-RS资源为第一PRB中的第一N端口CSI-RS子资源与第二PRB中的第二N端口CSI-RS子资源;或,所述2N端口CSI-RS资源为为第一PRB中的第一2N端口CSI-RS子资源的一半与所述第二PRB中的第二2N端口CSI-RS子资源的一半。
假设两个PRB内的N端口CSI-RS资源为4端口CSI-RS资源,第一PRB中的第一4端口CSI-RS子资源与第二PRB中的第二4端口CSI-RS子资源进行聚合,得到8端口CSI-RS资源,第一4端口CSI-RS子资源与第二4端口CSI-RS子资源的时频域位置相同;第一PRB中的第一8端口CSI-RS子资源的一半与第二PRB中的第二8端口CSI-RS子资源的一半进行聚合,得到8端口CSI-RS资源,第一8端口CSI-RS子资源的一半与第二8端口CSI-RS子资源的一半的时频域位置相同,且所截取一半的位置也相同,这样做的好处是,对于低于第14版本的终端设备,可以视作静默的CSI-RS资源,从而不会增加终端设备的额外导频开销。

所述终端设备接收多个2N端口CSI-RS资源的资源序号;
所述终端设备根据所述多个2N端口CSI-RS资源的资源序号得到4(2K+1)端口CSI-RS资源,所述4(2K+1)端口CSI-RS资源由所述多个2N端口CSI-RS资源配置得到,所述多个2N端口CSI-RS资源包括第一CSI-RS资源和第二CSI-RS资源,所述第一CSI-RS资源为处于同一PRB中的2N端口CSI-RS资源,所述第二CSI-RS资源为处于两个不同PRB中的2N端口CSI-RS资源,K为正整数。
接入网设备在发送2N端口的CSI-RS资源序号之前,由于2N端口CSI-RS资源是存在多个的,那么需要配置多个2N端口CSI-RS资源得到4(2K+1)端口CSI-RS资源,并且将多个2N端口CSI-RS资源的资源序号发送至终端设备,终端设备根据多个2N端口CSI-RS资源的资源序号就可以得到4(2K+1)端口CSI-RS资源,多个2N端口CSI-RS资源包括第一CSI-RS资源和第二CSI-RS资源,第一CSI-RS资源为处于同一PRB中的2N端口CSI-RS资源,第二CSI-RS资源为处于两个不同PRB中的2N端口CSI-RS资源,K为正整数。

接入网设备在发送2N端口的CSI-RS资源序号之前,是按照预先设置的编号规则配置2N端口CSI-RS资源得到4(2K+1)端口CSI-RS资源的,由于预先设置的编号规则是共知的,那么终端设备按照编号规则优先对处于同一PRB中的2N端口CSI-RS资源(即第一CSI-RS资源)对应的端口进行编号,再对处于两个不同PRB中的2N端口CSI-RS资源(即第二CSI-RS资源)对应的端口进行编号,这样做的好处是可以保证较好的前向兼容特性,而且预先设置的编号规则是接入网设备和终端设备所共知的。

4(2K+1)端口CSI-RS资源的CDM配置是接入网设备发送2N端口的CSI-RS资源序号时使用的,而接入网设备对4(2K+1)端口CSI-RS资源进行CDM配置是共知的,那么4(2K+1)端口CSI-RS资源的CDM配置对于终端设备来说是已知的,由于第一CSI-RS资源为处于同一PRB中的2N端口CSI-RS资源,为了保证CDM跨越资源粒子(RE)的信道状态一致性,需要尽可能减少频域跨度,最大间隔不超过6个子载波(即6个RE),因此第一CSI-RS资源为2N路CDM的方式;而对于第二CSI-RS资源为处于两个不同PRB中的2N端口CSI-RS资源,为了节省CDM资源,因此第二CSI-RS资源为N路CDM的方式,并且进行3dB功率放大处理,这样可以保证所有端口上的功率一致性。

假设两个PRB内的N端口CSI-RS资源为4端口CSI-RS资源,第一PRB中的第一4端口CSI-RS子资源与第二PRB中的第二4端口CSI-RS子资源进行聚合,得到8端口CSI-RS资源,第一4端口CSI-RS子资源与第二4端口CSI-RS子资源的时频域位置相同;第一PRB中的第一8端口CSI-RS子资源的一半与第二PRB中的第二8端口CSI-RS子资源的一半进行聚合,得到8端口CSI-RS资源,第一8端口CSI-RS子资源的一半与第二8端口CSI-RS子资源的一半的时频域位置相同,且所截取一半的位置也相同,这样做的好处是,对于低于第14版本的终端设备,可以视作静默的CSI-RS资源,从而不会增加终端设备的额外导频开销。
结合本发明第四方面第一实施方式,本发明第四方面第二实施方式中,
所述接收模块,还用于接收多个2N端口CSI-RS资源的资源序号;
所述处理模块,还用于根据所述多个2N端口CSI-RS资源的资源序号得到4(2K+1)端口CSI-RS资源,所述4(2K+1)端口CSI-RS资源由所述多个2N端口CSI-RS资源配置得到,所述多个2N端口CSI-RS资源包括第一CSI-RS资源和第二CSI-RS资源,所述第一CSI-RS资源为处于同一PRB中的2N端口CSI-RS资源,所述第二CSI-RS资源为处于两个不同PRB中的2N端口CSI-RS资源,K为正整数。
接入网设备在发送2N端口的CSI-RS资源序号之前,由于2N端口CSI-RS资源是存在多个的,那么需要配置多个2N端口CSI-RS资源得到4(2K+1)端口CSI-RS资源,并且将多个2N端口CSI-RS资源的资源序号发送至终端设备,处理模块根据接收模块接收到的多个2N端口CSI-RS资源的资源序号就可以得到4(2K+1)端口CSI-RS资源,多个2N端口CSI-RS资源包括第一CSI-RS资源和第二CSI-RS资源,第一CSI-RS资源为处于同一PRB中的2N端口CSI-RS资源,第二CSI-RS资源为处于两个不同PRB中的2N端口CSI-RS资源,K为正整数。
结合本发明第四方面第二实施方式,本发明第四方面第三实施方式中,
所述处理模块,还用于对所述4(2K+1)端口CSI-RS资源进行端口编号;
所述处理模块包括:
编号单元,用于对所述第一CSI-RS资源对应的端口进行编号;
所述编号单元,还用于对所述第二CSI-RS资源对应的端口进行编号。
接入网设备在发送2N端口的CSI-RS资源序号之前,是按照预先设置的编号规则配置2N端口CSI-RS资源得到4(2K+1)端口CSI-RS资源的,由于预先设置的编号规则是共知的,那么处理模块中的编号单元按照编号规则优先对处于同一PRB中的2N端口CSI-RS资源(即第一CSI-RS资源)对应的端口进行编号,再对处于两个不同PRB中的2N端口CSI-RS资源(即第二CSI-RS资源)对应的端口进行编号,这样做的好处是可以保证较好的前向兼容特性,而且预先设置的编号规则是接入网设备和终端设备所共知的。
结合本发明第四方面第二实施方式,本发明第四方面第四实施方式中,
所述处理模块,还用于获取所述4(2K+1)端口CSI-RS资源的CDM配置,所述4(2K+1)端口CSI-RS资源的CDM配置包括所述第一CSI-RS资源为2N路CDM的方式及所述第二CSI-RS资源为N路CDM的方式。
4(2K+1)端口CSI-RS资源的CDM配置是接入网设备发送的,而4(2K+1)端口CSI-RS资源进行2N路CDM配置的具体实施方式是共知的,那么4(2K+1)端口CSI-RS资源的CDM配置对于处理模块来说是已知的,由于第一CSI-RS资源为处于同一PRB中的2N端口CSI-RS资源,因此第一CSI-RS资源为2N路CDM的方式;而对于第二CSI-RS资源为处于两个不同PRB中的2N端口CSI-RS资源,为了节省CDM资源,因此第二CSI-RS资源为N路CDM的方式,并且进行3dB功率放大处理,这样可以保证所有端口上的功率一致性。另外,为了保证CDM跨越资源粒子(RE)的信道状态一致性,需要尽可能减少频域跨度,最大间隔不超过6个子载波(即6个RE)。
本发明第五方面提供一种接入网设备,包括:处理器、发射器及存储器,其中,存储器可以用于存储处理器执行的代码;
所述发射器,用于向终端设备发送一个2N端口的CSI-RS资源序号,所述2N端口的CSI-RS资源序号用于通知所述终端设备处于两个相邻PRB中的N端口CSI-RS资源,N为正整数。
发射器向终端设备发送一个2N端口的CSI-RS资源序号,使得终端设备可以确定处于两个相邻PRB中的N端口CSI-RS资源,由于2N端口CSI-RS资源是由不同PRB中的N端口CSI-RS子资源聚合得到的,那么在现有技术中,24,32端口CSI-RS资源使用8端口CSI-RS资源聚合得到的情况下,利用多个8端口资源序号也能对20,28端口CSI-RS资源进行配置,从而可以减小信令开销,对现有标准的影响也较小;而与现有技术相比,在20端口的情况下,进行CDM-8配置时,无需在每个CDM分组里,去掉3组CDM;而在28端口的情况下,无需在每个CDM分组里,去掉1组CDM,因此本方案在4(2K+1)端口时,例如20端口或28端口,不会存在资源浪费。
本发明第六方面提供一种终端设备,包括:处理器、接收器及存储器,其中,存储器可以用于存储处理器执行的代码;
所述接收器,用于接收接入网设备发送的一个2N端口的CSI-RS资源序号;
所述处理器,用于根据所述2N端口的CSI-RS资源序号确定处于两个相邻PRB中的N端口CSI-RS资源,N为正整数。
接收器接收接入网设备发送的资源序号及2N端口配置信息,资源序号用于指示2N端口信道测量导频信号CSI-RS资源,2N端口配置信息用于指示2N端口CSI-RS资源的2N路码分复用CDM配置,N端口CSI-RS资源由两个处于不同物理资源块PRB中的N端口CSI-RS资源聚合而成,处理器确定2N端口的CSI-RS配置,由于2N端口CSI-RS资源是由不同PRB中的N端口CSI-RS子资源聚合得到的,那么在现有技术中,24,32端口CSI-RS资源使用8端口CSI-RS资源聚合得到的情况下,利用多个8端口资源序号也能对20,28端口CSI-RS资源进行配置,从而可以减小信令开销,对现有标准的影响也较小;而与现有技术相比,在20端口的情况下,进行CDM-8配置时,无需在每个CDM分组里,去掉3组CDM;而在28端口的情况下,无需在每个CDM分组里,去掉1组CDM,因此本方案在4(2N+1)端口时,例如20端口或28端口,不会存在资源浪费。

具体实施方式
本发明提供信号资源配置方法、终端及接入网设备,用于降低对现有标准的影响,节约CSI-RS的资源。
为了使本技术领域的人员更好地理解本发明方案,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分的实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都应当属于本发明保护的范围。
首先简单介绍本发明应用的系统构架或场景。
本发明应用于无线通信网络系统,可以应用于LTE系统,以及一切基于LTE标准的终端设备和接入网设备,如图1所示,接入网设备与核心网连接,接入网设备覆盖的小区中包含N个终端设备,接入网设备和每个终端设备建立通信链路。
接入网设备可以是小区的网络设备,可以是小区层面意义上的基站或者具有类似于基站的功能的网络设备,例如无线路由器和无线接入点(Access Point,AP)等。接入网设备可以是为小区内移动或固定不动的终端设备提供无线接入和通信服务的网络设备。
终端设备可以为手机、智能终端、多媒体设备、流媒体设备及MTC终端设备等。
在LTE的第13个版本中,引入了D-MIMO技术,即在接入网设备借助2 维天线阵列,同时进行水平维度和垂直维度波束赋型,并据此进行相应的预编码码本增强及反馈流程增强等,可以显著地提升小区容量。第13版本的FD-MIMO最多支持16个天线阵元,为了测量这16个天线阵元的信道特征,设计了16个端口的信道状态信息的参考信号(Channel State Information Reference Signal,CSI-RS)。而到了第14版本,目前正讨论将阵元数升级到{20,24,28,32}个。因此,对{20,24,28,32}阵元的信道测量,需要{20,24,28,32}端口的CSI-RS来支持。
在第13版本的FD-MIMO中,16天线端口的CSI-RS是通过将两组8天线端口的CSI-RS聚合来得到,而12天线端口的CSI-RS是通过将三组4天线端口的CSI-RS聚合来得到,同时,为了保证在每个OFDM符号上的CSI-RS的功率,16天线端口和12天线端口使用了正交码进行多个端口参考信号在相同时频资源组上的CDM,来进行功率提升。如图2所示为CDM-2的情形,针对CDM-4,16端口聚合方式为{0,1,4,5}、{2,3,6,7}、{8,9,12,13}和{10,11,14,15},如图3所示为12端口的聚合方式为{0,1,2,3}、{4,5,6,7}和{8,9,10,11}。
在3GPP RAN1#85中,大唐电信(CATT)提出了一种CSI-RS资源设计的方案,该方案也被爱立信(Ericsson)所支持(R1-167634)。其设计方式如图4所示,重新定义用于聚合出32端口CSI-RS的8端口CSI-RS,对于32端口,采用4组新定义的8端口CSI-RS进行聚合,在新定义的8端口CSI-RS上,采用CDM-8进行码分复用,从而实现功率的有效利用。在32端口的基础上,在每个CDM分组里,去掉3组CDM不用得到20端口的;在32端口的基础上,在每个CDM分组里,去掉2组CDM不用得到24端口的;在32端口的基础上,在每个CDM分组里,去掉1组CDM不用得到28端口的。即20、24和28端口对CSI-RS资源粒子的占用,与32端口的完全一致。
下面通过实施例对应用于上述系统构架或场景中的接入网设备和终端设备之间的交互的信号资源配置方法进行说明。
请参阅图5,本发明实施例提供一种信号资源配置方法,包括:
501、接入网设备向终端设备发送一个2N端口的CSI-RS资源序号,终端设 备接收接入网设备发送的一个2N端口的CSI-RS资源序号;
本实施例中,接入网设备发送的一个2N端口的CSI-RS资源序号用于通知终端设备处于两个相邻PRB中的N端口CSI-RS资源,N为正整数,例如PRB1和PRB2相邻,PRB1中的一个4端口CSI-RS子资源和PRB2中的一个4端口CSI-RS子资源。基于本方案需要解决的问题,是8端口CSI-RS资源的问题,那么N等于4,而应用的场景可以是4(2K+1)端口CSI-RS资源的情形,K为2时,是20端口,K为3时,是28端口,这都是现有技术存在缺陷的场景,具体在实际应用中,端口数量更多的场景也有可能,因此N=4和K=2或3只是应用于本实施例中,具体的数值不做限定。终端设备接收接入网设备发送的2N端口的CSI-RS资源序号。2N端口的CSI-RS资源序号可以是通过如下方式定义:针对图8所示的20端口的场景中,使用现有的4端口CSI-RS资源序号可以得到8端口的CSI-RS资源序号,如表1所示
表1
Figure PCTCN2016101607-appb-000001
Figure PCTCN2016101607-appb-000002
Figure PCTCN2016101607-appb-000003
从表1中可以看出,在8端口的CSI-RS资源序号的配置上,对资源序号10到19,复用了4端口CSI-RS资源序号0-9的配置,同样,对于资源序号26-31,复用了4端口CSI-RS资源序号20-25。由于这些针对8端口CSI-RS资源序号本身并没有定义,因此在这里增加这样的定义,对标准影响很小。2N端口的CSI-RS资源序号发送方式,可以是半静态的,例如通过无线资源控制协议(Radio Resource Control,RRC),也可以是动态的,例如通过下行控制信息(Downlink Control Information,DCI),终端设备通过RRC信令或者DCI可以获得2N端口的CSI-RS资源序号。
502、终端设备根据2N端口的CSI-RS资源序号确定处于两个相邻PRB中的N端口CSI-RS资源。
本实施例中,终端设备接收到2N端口的CSI-RS资源序号之后,由于2N端口的CSI-RS资源序号明确的指示了两个相邻PRB中的N端口CSI-RS资源,那么终端设备根据根据2N端口的CSI-RS资源序号可以确定处于两个相邻PRB中的N端口CSI-RS资源,从而可以接收到接入网设备在两个相邻PRB中的N端口CSI-RS资源中发送的参考信号。
本发明实施例中,由于2N端口CSI-RS资源是由不同PRB中的N端口CSI-RS子资源聚合得到的,那么在现有技术中,24和32端口CSI-RS资源使用8端口CSI-RS资源聚合得到的情况下,利用多个8端口资源序号也能对20和28端口CSI-RS资源进行配置,从而可以减小信令开销,对现有标准的影响也较小;而与现有技术相比,在20端口的情况下,进行CDM-8配置时,无需在每个CDM 分组里,去掉3组CDM;而在28端口的情况下,无需在每个CDM分组里,去掉1组CDM,因此本方案在4(2K+1)端口时,例如20端口或28端口,不会存在资源浪费。
可选的,本发明的一些实施例中,
2N端口的CSI-RS资源序号用于指示一个处于两个不同PRB中的2N端口CSI-RS资源;
2N端口CSI-RS资源为第一PRB中的第一N端口CSI-RS子资源与第二PRB中的第二N端口CSI-RS子资源;或,2N端口CSI-RS资源为第一PRB中的第一2N端口CSI-RS子资源的一半与第二PRB中的第二2N端口CSI-RS子资源的一半。
本发明实施例中,假设两个PRB内的N端口CSI-RS子资源为4端口的,以图6为例,对第一PRB(PRB1)中的第一4端口CSI-RS子资源与第二PRB(PRB2)中的第二4端口CSI-RS子资源进行聚合,得到8端口CSI-RS资源,第一4端口CSI-RS子资源中的{0,1}和第二4端口CSI-RS子资源中的{4,5}时频域位置相同,第一4端口CSI-RS子资源中的{2.3}和第二4端口CSI-RS子资源中的{6,7}时频域位置相同。以图7为例,将第一PRB(PRB1)中的第一8端口CSI-RS子资源的一半{0,1,2,3}与第二PRB(PRB2)中的第二8端口CSI-RS子资源的一半{4,5,6,7}进行聚合,得到8端口CSI-RS资源,第一8端口CSI-RS子资源的一半{0,1,2,3}与第二8端口CSI-RS子资源的一半{4,5,6,7}的时频域位置相同。针对20端口的场景下的CSI-RS资源如图8所示,对于一个20端口的CSI-RS资源,PRB1中的4端口CSI-RS子资源{31,32}和{33,34},与PRB2中的4端口CSI-RS子资源{31,32}和{33,34}聚合成为8端口CSI-RS资源。针对28端口的场景下的CSI-RS资源如图9所示,PRB1中8端口CSI-RS子资源的一半{37,38,39,40}与PRB2中8端口CSI-RS子资源的一半{37,38,39,40}聚合成为8端口CSI-RS资源,需要说明的是,图9中剩下的PRB1中的8端口CSI-RS子资源的一半{31,32,35,36}和PRB2中的8端口CSI-RS子资源的一半{31,32,35,36}无法用于LTE先前版本终端的数据传输,但可以用于LTE后续版本终端的数据传输,也可以用作后续版本终端的非周期CSI-RS资源或被其它小区复用。
基于以上的实施例,接入网设备就可以配置多个2N端口的CSI-RS资源, 从而聚合得到4(2K+1)端口CSI-RS资源。
可选的,本发明的一些实施例中,信号资源配置方法还包括:
接入网设备配置多个2N端口CSI-RS资源得到4(2K+1)端口CSI-RS资源,多个2N端口CSI-RS资源包括第一CSI-RS资源和第二CSI-RS资源,第一CSI-RS资源为处于同一PRB中的2N端口CSI-RS资源,第二CSI-RS资源为处于两个不同PRB中的2N端口CSI-RS资源,K为正整数;
接入网设备将多个2N端口CSI-RS资源的资源序号发送至终端设备。
本发明实施例中,接入网设备配置多个2N端口的CSI-RS资源,得到4(2K+1)端口CSI-RS资源,而2N端口CSI-RS资源包括第一CSI-RS资源和第二CSI-RS资源,第一CSI-RS资源为处于同一PRB中的2N端口CSI-RS资源,第二CSI-RS资源为处于两个不同PRB中的2N端口CSI-RS资源,如图8所示,PRB1中的{15,16,19,20}和{17,18,21,22},PRB1中的{23,24,27,28}和{25,26,29,30},PRB2中的{15,16,19,20}和{17,18,21,22},PRB2中的{23,24,27,28}和{25,26,29,30}是第一CSI-RS资源;而PRB1中的{31,32}、{33,34}与PRB2中的{31,32}、{33,34}为第二CSI-RS资源,,在得到4(2K+1)端口CSI-RS资源之后,接入网设备将多个2N端口CSI-RS资源的资源序号发送给终端设备,使得终端设备根据多个2N端口CSI-RS资源的资源序号能够确定4(2K+1)端口CSI-RS资源。
上述实施例中,接入网设备配置2N端口CSI-RS资源得到4(2K+1)端口CSI-RS资源的过程中,需要对4(2K+1)个端口进行编号,下面通过实施进行具体细化,并且同时对4(2K+1)端口CSI-RS资源进行CDM配置进行说明,具体如下:
请参阅图10,本发明实施例提供一种信号资源配置方法,包括:
1001、接入网设备配置多个2N端口CSI-RS资源得到4(2K+1)端口CSI-RS资源;
本实施例中,接入网设备在发送2N端口的CSI-RS资源序号之前,需要对2N端口的CSI-RS资源进行配置,以聚合得到4(2K+1)端口CSI-RS资源,而2N端口CSI-RS资源包括第一CSI-RS资源和第二CSI-RS资源,第一CSI-RS资源 为处于同一PRB中的2N端口CSI-RS资源第一种实现方式如图8所示,对于一个20端口的CSI-RS资源,PRB1中的4端口CSI-RS资源{31,32}和{33,34},与PRB2中的4端口CSI-RS资源{31,32}和{33,34}聚合成为8端口CSI-RS资源,第二CSI-RS资源为处于两个不同PRB中的2N端口CSI-RS资源,K为正整数。
1002、接入网设备对4(2K+1)端口CSI-RS资源进行端口编号;
本实施例中,接入网设备对4(2K+1)端口CSI-RS资源进行端口编号具体为:接入网设备先对第一CSI-RS资源对应的端口进行编号,再对第二CSI-RS资源对应的端口进行编号,编号的结果如图8所示,PRB1中的{31,32}和{33,34}与PRB2中的{31,32}和{33,34}是第二CSI-RS资源。
1003、接入网设备对4(2K+1)端口CSI-RS资源进行CDM配置;
本实施例中,接入网设备在发送2N端口的CSI-RS资源序号之前,需要采用CDM技术对4(2K+1)端口的CSI-RS资源进行CDM配置,具体过程为:对第一CSI-RS资源配置CDM-8,即对处于同一PRB中的8端口CSI-RS资源配置CDM-8;对第二CSI-RS资源配置CDM-4,即8端口CSI-RS资源的一半处于PRB1中,一半处于PRB2中,PRB1中的一半进行CDM-4配置,并且进行3dB功率放大处理,PRB2中的一半也做相同处理,如图11中所示,PRB1中的两个8端口CSI-RS资源{{0,1,4,5},{2,3,6,7}}配置CDM-8;而第二CSI-RS资源中的一半{{0,1},{2,3}}配置CDM-4,并且引入3dB的功率提升,从而保证所有端口上功率一致;另外,为了保证CDM跨越资源粒子(RE)的信道状态一致性,需要尽可能减少频域跨度,最大间隔不超过6个子载波(即6个RE)。虽然CDM是接入网设备配置的,但是2N路CDM的具体配置方式是预先设置的,而且2N路CDM的具体配置的方式是接入网设备和终端设备所共知的。
1004、接入网设备将多个2N端口CSI-RS资源的资源序号发送至终端设备,终端设备接收多个2N端口CSI-RS资源的资源序号;
本实施例中,在得到4(2K+1)端口CSI-RS资源之后,接入网设备将多个2N端口CSI-RS资源的资源序号发送给终端设备,使得终端设备根据多个2N端口CSI-RS资源的资源序号能够确定4(2K+1)端口CSI-RS资源。
1005、终端设备根据多个2N端口CSI-RS资源的资源序号得到4(2K+1)端口 CSI-RS资源;
本实施例中,终端设备根据多个2N端口CSI-RS资源的资源序号能够确定4(2K+1)端口CSI-RS资源。
1006、终端设备对4(2K+1)端口CSI-RS资源进行端口编号;
本实施例中,终端设备对得到的4(2K+1)端口CSI-RS资源进行端口编号具体为:先对第一CSI-RS资源对应的端口进行编号,后对第二CSI-RS资源对应的端口进行编号,而且编号规则是预先设置的,并且接入网设备和终端设备共知,那么终端设备在接收2N端口的CSI-RS资源序号之前,对第一CSI-RS资源对应的端口进行编号,对第二CSI-RS资源对应的端口进行编号。
1007、终端设备获取4(2K+1)端口CSI-RS资源的CDM配置;
本实施例中,由于CDM配置的方式是接入网设备和终端设备所共知的,4(2K+1)端口CSI-RS资源的CDM配置包括第一CSI-RS资源为2N路CDM的方式及第二CSI-RS资源为N路CDM的方式。
本实施例中,终端设备接收到2N端口的CSI-RS资源序号之后,2N端口的CSI-RS资源序号明确的指示了两个相邻PRB中的N端口CSI-RS资源,那么终端设备根据根据2N端口的CSI-RS资源序号可以确定处于两个相邻PRB中的N端口CSI-RS资源,从而可以接收到接入网设备在两个相邻PRB中的N端口CSI-RS资源中发送的信息。
需要说明的是,以上实施例中配置2N端口CSI-RS资源得到4(2K+1)端口CSI-RS资源是按照预先设置的编号规则进行配置,对4(2K+1)端口CSI-RS资源进行CDM配置的2N路CDM具体配置方式也是预先设置的,而且接入网设备和终端设备所共知,这样做可以节省信令的开销,但是不限于通过预先设置的规则的方式,接入网设备也可以在得到4(2K+1)端口CSI-RS资源之后,通过配置信息告知终端设备。
上述实施例对信号资源配置方法进行了说明,以下实施例对接入网设备和终端设备分别进行说明。
请参阅图12,本发明实施例提供一种接入网设备,包括:
发送模块1201,用于向终端设备发送一个2N端口的信道测量导频信号CSI-RS资源序号,2N端口的CSI-RS资源序号用于通知终端设备处于两个相邻物理资源块PRB中的N端口CSI-RS资源,N为正整数。
本发明实施例中,发送模块1201向终端设备发送一个2N端口的CSI-RS资源序号,使得终端设备可以确定处于两个相邻PRB中的N端口CSI-RS资源,由于2N端口CSI-RS资源是由不同PRB中的N端口CSI-RS子资源聚合得到的,那么在现有技术中,24,32端口CSI-RS资源使用8端口CSI-RS资源聚合得到的情况下,利用多个8端口资源序号也能对20,28端口CSI-RS资源进行配置,从而可以减小信令开销,对现有标准的影响也较小;而与现有技术相比,在20端口的情况下,进行CDM-8配置时,无需在每个CDM分组里,去掉3组CDM;而在28端口的情况下,无需在每个CDM分组里,去掉1组CDM,因此本方案在4(2K+1)端口时,例如20端口或28端口,不会存在资源浪费。

发送模块1201,还用于将多个2N端口CSI-RS资源的资源序号发送至终端设备。
本发明实施例中,发送模块1201在发送2N端口的CSI-RS资源序号之前,处理模块1202需要配置多个2N端口的CSI-RS资源,得到4(2K+1)端口CSI-RS资源,而N端口CSI-RS资源包括第一CSI-RS资源和第二CSI-RS资源,第一 CSI-RS资源为处于同一PRB中的2N端口CSI-RS资源,第二CSI-RS资源为处于两个不同PRB中的2N端口CSI-RS资源,K为正整数。

处理模块1202包括:
编号单元1203,用于对第一CSI-RS资源对应的端口进行编号;
编号单元1203,还用于对第二CSI-RS资源对应的端口进行编号。
本发明实施例中,处理模块1202中的编号单元1203按照预先设置的编号规则,需要优先对处于同一PRB中的2N端口CSI-RS资源(即第一CSI-RS资源)对应的端口进行编号,再对处于两个不同PRB中的2N端口CSI-RS资源(即第二CSI-RS资源)对应的端口进行编号,这样做的好处是可以保证较好的前向兼容特性,而且预先设置的编号规则是接入网设备和终端设备所共知的。
可选的,本发明的一些实施例中,

本发明实施例中,处理模块1202中的CDM配置单元1204对第一CSI-RS资源上的2N端口CSI-RS资源配置2N路CDM;而对于第二CSI-RS资源为处于两个不同PRB中的2N端口CSI-RS资源,CDM配置单元1204对2N端口CSI-RS资源配置N路CDM即可,并且进行3dB功率放大处理,这样可以保证所有端口上的功率一致性。另外,为了保证CDM跨越资源粒子(RE)的信道状态一致性,需要尽可能减少频域跨度,最大间隔不超过6个子载波(即6个RE)。
请参阅图13,本发明实施例提供一种终端设备,包括:
接收模块1301,用于接收接入网设备发送的2N端口的CSI-RS资源序号;
处理模块1302,用于根据2N端口的CSI-RS资源序号确定处于两个相邻PRB中的N端口CSI-RS资源,N为正整数。
本发明实施例中,接收模块1301接收接入网设备发送的资源序号及2N端口配置信息,资源序号用于指示2N端口信道测量导频信号CSI-RS资源,2N端口配置信息用于指示2N端口CSI-RS资源的CDM配置,2N端口CSI-RS资源由两个处于不同PRB中的N端口CSI-RS子资源聚合而成,处理模块1302确定2N端口的CSI-RS配置,由于2N端口CSI-RS资源是由不同PRB中的N端口CSI-RS资源聚合得到的,那么在现有技术中,24,32端口CSI-RS资源使用8端口CSI-RS资源聚合得到的情况下,利用多个8端口资源序号也能对20,28端口CSI-RS资源进行配置,从而可以减小信令开销,对现有标准的影响也较小;而与现有技术相比,在20端口的情况下,进行CDM-8配置时,无需在每个CDM分组里,去掉3组CDM;而在28端口的情况下,无需在每个CDM分组里,去掉1组CDM,因此本方案在4(2N+1)端口时,例如20端口或28端口,不会存在资源浪费。
可选的,本发明的一些实施例中,
2N端口的CSI-RS资源序号用于指示一个处于两个不同PRB中的2N端口CSI-RS资源;
2N端口CSI-RS资源为第一PRB中的第一N端口CSI-RS子资源与第二PRB中的第二N端口CSI-RS子资源;或,2N端口CSI-RS资源为为第一PRB中的第一2N端口CSI-RS子资源的一半与第二PRB中的第二2N端口CSI-RS子资源的一半。
可选的,本发明的一些实施例中,
接收模块1301,还用于接收多个2N端口CSI-RS资源的资源序号;
处理模块1302,还用于根据所述多个2N端口CSI-RS资源的资源序号得到4(2K+1)端口CSI-RS资源,所述4(2K+1)端口CSI-RS资源由所述多个2N端口CSI-RS资源配置得到,所述多个2N端口CSI-RS资源包括第一CSI-RS资源和第二CSI-RS资源,所述第一CSI-RS资源为处于同一PRB中的2N端口CSI-RS资源,所述第二CSI-RS资源为处于两个不同PRB中的2N端口CSI-RS资源,K为正整数。
本发明实施例中,接入网设备在发送2N端口的CSI-RS资源序号之前需要配置多个2N端口的CSI-RS资源进行配置,得到4(2K+1)端口CSI-RS资源, 而终端设备配置的方式与接入网设备是相同的,处理模块1302也需要配置多个2N端口CSI-RS资源得到4(2K+1)端口CSI-RS资源,2N端口CSI-RS资源包括第一CSI-RS资源和第二CSI-RS资源,第一CSI-RS资源为处于同一PRB中的2N端口CSI-RS资源,第二CSI-RS资源为处于两个不同PRB中的2N端口CSI-RS资源,K为正整数。
可选的,本发明的一些实施例中,
处理模块1302,还用于对4(2K+1)端口CSI-RS资源进行端口编号;
处理模块1302包括:
编号单元1303,用于对第一CSI-RS资源对应的端口进行编号;
编号单元1303,还用于对第二CSI-RS资源对应的端口进行编号。
本发明实施例中,接入网设备在发送2N端口的CSI-RS资源序号之前,是按照预先设置的编号规则配置2N端口CSI-RS资源得到4(2K+1)端口CSI-RS资源的,由于预先设置的编号规则是共知的,那么处理模块1302中的编号单元1303按照编号规则优先对处于同一PRB中的2N端口CSI-RS资源(即第一CSI-RS资源)对应的端口进行编号,再对处于两个不同PRB中的2N端口CSI-RS资源(即第二CSI-RS资源)对应的端口进行编号,这样做的好处是可以保证较好的前向兼容特性,而且预先设置的编号规则是接入网设备和终端设备所共知的。
可选的,本发明的一些实施例中,
处理模块1302,还用于获取4(2K+1)端口CSI-RS资源的CDM配置,4(2K+1)端口CSI-RS资源的CDM配置包括第一CSI-RS资源为2N路CDM的方式及第二CSI-RS资源为N路CDM的方式。
本发明实施例中,4(2K+1)端口CSI-RS资源的CDM配置是接入网设备发送的,而接入网设备对4(2K+1)端口CSI-RS资源进行CDM配置的具体方式是共知的,那么4(2K+1)端口CSI-RS资源的CDM配置对于处理模块来说是已知的。第一CSI-RS资源为2N路CDM的方式;而对于第二CSI-RS资源为处于两个不同PRB中的2N端口CSI-RS资源,为了节省CDM资源,因此第二CSI-RS资源为N路CDM的方式,并且进行3dB功率放大处理,这样可以保证所有端口上的功率 一致性。另外,为了保证CDM跨越资源粒子(RE)的信道状态一致性,需要尽可能减少频域跨度,最大间隔不超过6个子载波(即6个RE)。

本发明实施例中,发射器1402向终端设备发送一个2N端口的CSI-RS资源序号,使得终端设备可以确定处于两个相邻PRB中的N端口CSI-RS资源,由于2N端口CSI-RS资源是由不同PRB中的N端口CSI-RS子资源聚合得到的,那么在现有技术中,24,32端口CSI-RS资源使用8端口CSI-RS资源聚合得到的情况下,利用多个8端口资源序号也能对20,28端口CSI-RS资源进行配置,从而可以减小信令开销,对现有标准的影响也较小;而与现有技术相比,在20端口的情况下,进行CDM-8配置时,无需在每个CDM分组里,去掉3组CDM;而在28端口的情况下,无需在每个CDM分组里,去掉1组CDM,因此本方案在4(2K+1)端口时,例如20端口或28端口,不会存在资源浪费。
