图1示出了根据本申请实施例的传输上行解调参考信号的方法。如图1所示,方法100包括:
S110,终端设备接收网络设备发送的第一解调参考信号DMRS配置信息,所述第一DMRS配置信息用于指示DMRS序列的类型;
S120,所述终端设备接收所述网络设备发送的第二DMRS配置信息,所述第二DMRS配置信息能够用于指示下列配置参数中的至少一种:DMRS的天线端口配置、DMRS的物理资源配置和DMRS的序列配置;
S130,所述终端设备根据所述第一DMRS配置信息,确定所述第二DMRS配置信息所指示的配置参数;
S140,所述终端设备根据所述第二DMRS配置信息所指示的配置参数,确定DMRS的传输参数;
S150,所述终端设备根据所述传输参数向所述网络设备传输DMRS。
根据本申请实施例的传输上行解调参考信号的方法,终端设备根据用于指示DMRS序列的类型的第一DMRS配置信息,确定DMRS序列的类型,并根据DMRS序列的类型确定第二DMRS配置信息所指示的配置参数,根据确定的配置参数确定DMRS的传输参数,之后根据DMRS的传输参数传输DMRS。由此,终端设备能够根据第一DMRS配置信息和第二DMRS配 置信息,确定每种DMRS序列的传输参数,使得终端设备能够同时支持多种DRMS序列类型,并能够支持采用不同上行波形的终端设备或采用相同上行波形的终端设备间的资源复用,提高资源的利用率。
需要说明的是,S110和S120可以是两个不同的接收过程,S110和S120也可以是同一个接收过程。其中,S110和S120是同一个过程可以理解为第一DMRS配置信息和第二DMRS配置信息承载在同一个信息中,例如,承载在同一个下行控制信息(Downlink Control Information,DCI)中。
可选地,在S110中,第一DMRS配置信息指示DMRS序列为目标序列中的一种,所述目标序列至少包括伪随机(Pseudo Noise,PN)和Zadoff-Chu(ZC)序列。
可选地,在S120中,所述DMRS的天线端口配置包括所述DMRS占用的天线端口或所述DMRS占用的天线端口的数量。和/或,所述DMRS的物理资源配置包括下列配置中的至少一种:所述DMRS占用的正交频分复用OFDM符号的数量、所述DMRS占用的子载波(例如,奇数或偶数子载波)和所述DMRS的传输图样(Pattern),终端设备可以和网络设备事先约定几个传输Pattern,之后终端设备可以根据第二DMRS配置信息确定要采用的DMRS的传输Pattern。和/或,所述DMRS的序列配置包括下列配置中的至少一种:所述DMRS采用的序列循环移位、所述DMRS采用的正交覆盖码(Orthogonal Cover Code,OCC)、所述DMRS采用的根序列标识(Identification,ID)和所述DMRS采用的加扰序列ID。
可选地,在S140中,当终端设备确定第二DMRS配置信息指示DMRS的天线端口配置时,终端设备根据DMRS的天线端口配置确定DMRS占用的天线端口。
可选地,在S140中,当终端设备确定第二DMRS配置信息指示DMRS的天线端口配置时,终端设备根据DMRS的天线端口配置确定DMRS占用的物理资源。举例来说,DMRS的天线端口配置为天线端口数,如果第二DMRS配置信息指示DMRS占用的天线端口数小于或等于2,终端设备确定DMRS占用传输带宽中的每个物理资源块(Physical Resource Block,PRB)的奇数子载波,如果第二DMRS配置信息指示DMRS占用的天线端口数大于2,则终端设备确定DMRS占用传输带宽中的所有子载波。在具体实现时,网络设备和终端设备可以实现约定DMRS占用的天线端口数与占用的物理 资源的对应关系,网络设备也可以通过信令为终端设备配置DMRS占用的天线端口数与占用的物理资源的对应关系。
可选地,在S140中,当终端设备确定第二DMRS配置信息指示所述DMRS的天线端口配置时,终端设备根据所述DMRS的天线端口配置确定DMRS的发送功率。举例来说,DMRS的天线端口配置为DMRS占用的天线端口,网络设备和终端设备可以事先预定天线端口与发送功率的对应关系,终端设备根据第二DMRS配置信息指示的天线端口和上述的对应关系即可确定占用的天线端口对应的发送功率。或者DMRS的天线端口配置为DMRS占用的天线端口数,网络设备和终端设备可以事先预定天线端口数与发送功率的对应关系,终端设备根据第二DMRS配置信息指示的天线端口数和上述对应关系即可确定需要的发送功率。可以理解的是,网络设备可以将上述天线端口与发送功率的对应关系和天线端口数与发送功率的对应关系以信令的方式告知终端设备。
可选地,在S140中,当终端设备确定第二DMRS配置信息指示DMRS的天线端口配置时,终端设备根据DMRSDMRS的天线端口配置确定DMRS采用的序列循环移位和/或OCC,终端设备根据DMRS采用的序列循环移位和/或OCC产生DMRS序列。举例来说,DMRS的天线端口配置为DMRS占用的天线端口,不同的天线端口对应不同的序列循环移位和/或OCC。例如,假设有4个天线端口,编号分别为0、1、2和3,如果第二DMRS配置信息指示DMRS占用的天线端口为编号为0的天线端口,终端设备确定DMRS采用的序列循环移位为3,如果第二DMRS配置信息指示DMRS占用的天线端口为编号为1的天线端口,则终端设备确定DMRS采用的序列循环移位为1。在具体实现时,网络设备和终端设备可以实现约定DMRS占用的天线端口与采用的序列循环移位的对应关系,网络设备也可以通过信令为终端设备配置DMRS占用的天线端口与采用的序列循环移位的对应关系。
可选地,在S140中,当终端设备确定第二DMRS配置信息指示DMRS的序列配置时,终端设备根据DMRS的序列配置产生DMRS序列。例如,当第二DMRS配置信息指示DMRS采用的序列循环移位、DMRS采用的OCC或DMRS采用的根序列ID中的至少一项时,终端设备根据第二DMRS配置信息指示的序列循环移位、OCC或根序列ID产生DMRS序列。
可选地,在S140中,当所述终端设备确定所述第二DMRS配置信息指 示所述DMRS的物理资源配置时,终端设备根据所述DMRS的物理资源配置,确定所述DMRS占用的物理资源。
可选地,在S140中,当所述终端设备确定所述第二DMRS配置信息指示所述DMRS的物理资源配置时,所述终端设备根据所述DMRS的物理资源配置,确定所述DMRS的序列。举例来说,DMRS的物理资源配置为DMRS占用的ODFM符号,或者DMRS的物理资源配置为DMRS占用的子载波。例如,不同的OFDM符号上使用不同的DMRS序列,网络设备和终端设备可以事先约定OFDM符号和DMRS序列的对应关系,终端设备根据第二DMRS配置信息指示的OFDM符号和上述对应关系既可以确定DMRS序列。
可选地,在S140中,当所述终端设备确定所述第二DMRS配置信息指示所述DMRS的物理资源配置时,所述终端设备根据所述DMRS的物理资源配置,确定所述DMRS的发送功率。举例来说,DMRS的物理资源配置为DMRS占用的子载波。DMRS占用的子载波数量不同对应的DMRS的发送功率不同。网络设备和终端设备可以事先预定子载波数量与发送功率的对应关系,网络设备可以通过信令告知终端设备子载波数量与发送功率的对应关系。
可选地,在S150中,DMRS的传输参数包括下列参数中的至少一种:所述DMRS占用的天线端口、所述DMRS占用的物理资源和DMRS序列。终端设备在DMRS占用的物理资源上采用确定的天线端口和各天线端口的DMRS序列向网络设备传输DMRS信号以及上行数据。
在本申请实施例中,可选地,不同类型的DMRS序列对应的第二DMRS配置信息中包括的比特数相同。例如,当第一DMRS配置信息指示DMRS序列为PN序列时,第二DMRS配置信息包括M个比特,M为大于或等于1的正整数,并且当第一DMRS配置信息指示DMRS序列为ZC序列时,第二DMRS配置信息仍然包括M个比特。
进一步地,不同类型的DMRS序列对应的第二DMRS配置信息所指示的配置参数不同。也就是说,对于不同类型的DMRS序列,第二DMRS配置信息都包括M个比特,但这M个比特所指示的具体内容不同。
可选地,在一些实施例中,如果第一DMRS配置信息指示DMRS序列为PN序列,则第二DMRS配置信息指示DMRS的天线端口配置和所述DMRS的序列配置,例如,如表1中所示出的(假设M的值为4),第二DMRS 配置信息指示DMRS所用的天线端口和加扰序列。和/或,如果第一DMRS配置信息指示DMRS序列为ZC序列,则第二DMRS配置信息指示DMRS的序列配置,例如,如表2所示出的(假设M的值为4),第二DMRS配置信息指示所述DMRS采用的序列循环移位和/或OCC。
可以理解的是,表1中示出的第二DMRS配置信息、天线端口和加扰序列的对应关系可以是网络设备与终端设备事先约定好的。网络设备也可以将表1通过信令配置给终端设备。之后终端设备可以根据第二DMRS配置信息的值确定DMRS占用的天线端口和采用的加扰序列。同样的,表2示出的第二DMRS配置信息、天线端口和序列循环移位的对应关系可以是网络设备与终端设备事先约定好的。网络设备也可以将表2通过信令配置给终端设备,之后终端设备根据第二DMRS配置信息的值确定DMRS采用的序列循环移位。

可选地,在另一些实施例中,如果第一DMRS配置信息指示所述DMRS序列为PN序列,则所述第二DMRS配置信息指示所述DMRS的物理资源配置。例如,第二DMRS配置信息指示DMRS占用的子载波为奇数子载波还是偶数子载波,或者,第二DMRS配置信息指示DMRS占用的OFDM符号的数量。或者,如果第一DMRS配置信息指示DMRS序列为PN序列,在所述第二DMRS配置信息指示DMRS占用的天线端口,终端设备根据DMRS占用的天线端口可以确定DMRS占用的物理资源。
可选地,在另一些实施例中,如果所述第一DMRS配置信息指示所述DMRS序列为ZC序列,所述第二DMRS配置信息指示所述DMRS的序列配置,例如,第二DMRS配置信息指示DMRS采用的序列循环移位和/或根序列ID。在具体实现时,网络设备可以预先给终端设备配置多个根序列ID,终端设备根据第二DMRS配置信息的指示从多个根序列ID中选择需要采用的根序列ID。
在上述所有实施例中,网络设备可以通过高层信令向终端设备发送第一DMRS配置信息,网络设备也可以通过DCI向终端设备发送第一DMRS配置信息。
在上述所有实施例中,可选地,网络设备向终端设备发送用于调度上行数据传输的DCI,该DCI中包括N比特的DMRS配置信息,N为大于或等于2的正整数,N个比特中的1个比特用于承载第一DMRS配置信息,N个比特中的其余N-1个比特用于承载第二DMRS配置信息。也就是说,第一DMRS配置信息和第二DMRS配置信息承载在通过一个DCI中。终端设备根据DCI中的这1个比特确定DMRS序列的类型,例如,这1个比特的值取0表示PN序列,取1表示ZC序列。之后终端设备根据DMRS序列的类型确定DCI中的这N-1个比特指示的信息,确定DMRS占用的物理资源、天线端口和DMRS序列。
例如,如果DMRS序列为PN序列,终端设备根据N-1个比特指示的信息和表1确定出DMRS占用的天线端口和采用的加扰序列,之后根据占用的天线端口确定DMRS占用的物理资源,并根据加扰序列生成DMRS序列。或者,如果DMRS序列为ZC序列,终端设备根据N-1个比特指示的信息和表2确定出DMRS占用的各端口采用的序列循环移位,终端设备根据确定的序列循环移位生成DMRS序列,并且终端设备确定DMRS占用传输带宽中的所有子载波(与占用的天线端口数无关)。
