Description
本公开涉及通信技术领域,例如涉及一种上行参考信号的发送、接收处理方法、装置及基站、终端。
在长期演进(Long Term Evolution,LTE)中,物理下行控制信道(Physical Downlink Control Channel,PDCCH)用于承载上、下行调度信息,以及上行功率控制信息。下行控制信息(Downlink Control Information,DCI)格式(format)分为DCI format 0、1、1A、1B、1C、1D、2、2A、3和3A等,后面演进至LTE-A版本12(LTE-A Release 12)中又增加了DCI format 2B、2C、2D以支持多种不同的应用和传输模式。基站(e-Node-B,eNB)可以通过下行控制信息配置终端设备(User Equipment,UE),或者终端设备接受高层(higher layers)的配置,也称为通过高层信令来配置UE。
测量参考信号(Sounding Reference Signal,SRS)是一种终端设备与基站间用来测量无线信道信息(Channel State Information,CSI)的信号。在长期演进系统中,UE按照eNB指示的频带、频域位置、序列循环移位、周期和子帧偏置等参数,定时在发送子帧的最后一个数据符号上发送上行SRS。eNB根据接收到的SRS判断UE上行的CSI,并根据得到的CSI进行频域选择调度和闭环功率控制等操作。
在LTE-A版本10(LTE-A Release 10)的研究中提出:在上行通信中,应该使用非预编码的SRS,即:天线专有的SRS,而对PUSCH的用于解调的参考信号(De Modulation Reference Signal,DMRS)则进行预编码。基站通过接收非预编码的SRS,可估计出上行的原始CSI,而经过了预编码的DMRS则不能使基站估计出上行原始的CSI。此时,当UE使用多天线发送非预编码的SRS时,每个UE所需要的SRS资源都会增加,也就造成了系统内可以同时复用的UE数量下降。UE可通过高层信令(也称为通过触发类型0(trigger type 0)触发)或通过下行控制信息(也称为通过trigger type 1触发)这两种触发方式发送SRS,基于高层信令触发的为周期SRS,基于下行控制信息触发的为非周期SRS。 在LTE-A Release 10中增加了非周期发送SRS的方式,一定程度上改善了SRS资源的利用率,提高资源调度的灵活性。
随着通信技术的发展,数据业务需求量不断增加,可用的低频载波也已经非常稀缺,由此,基于还未充分利用的高频(30~300GHz)载波通信成为解决未来高速数据通信的重要通信手段之一。高频载波通信的可用带宽很大,可以提供有效的高速数据通信。但是,高频载波通信面临的一个很大的技术挑战就是:相对低频信号,高频信号在空间的衰落非常大,虽然会导致高频信号在室外的通信出现空间的衰落损耗问题,但是由于信号波长的减小,通常可以使用更多的天线,从而可以基于波束进行通信以补偿在空间的衰落损耗。
但是,当天线数增多时,由于此时需要每个天线都有一套射频链路,基于数字波束成型带来了增加成本和功率损耗的问题。因此,相关的研究中比较倾向于混合波束赋形,即射频波束和数字波束共同形成最终的波束。
在新的无线接入技术(New Radio Access Technology)的研究中,高频通信系统中,除了基站会配置大量的天线形成下行传输波束以补偿高频通信的空间衰落,用户终端同样也会配置大量的天线形成上行传输波束,此时SRS的发送也将采用波束的形式发送。在的SRS研究中,很可能会采用8端口的形式发送SRS,如何支持8端口的SRS资源复用,是一个待解决的问题。发送8端口和16端口的SRS资源复用问题,目前还没有有效的解决方案。

在步骤110中,基站确定终端发送M个端口或M层的上行参考信号所使用 的资源,M=8或16;
本实施例中,所述上行参考信号至少包括以下之一:测量或探测参考信号、上行解调参考信号和上行相位补偿参考信号。

本实施例中,基站确定终端发送M个端口或M层的上行参考信号所使用的资源,可以包括:确定所述M个端口或M层的上行参考信号在频域使用不同的发送梳作为正交的频域资源;但另一实施例中,所述M个端口或M层的上行参考信号在频域也可以使用不同的频段作为正交的频域资源。其中,发送梳也叫做频率梳。

本实施例中,所述指示信息中包含所述资源的部分配置信息,所述资源的其余配置信息由所述基站和终端双方预定义。
其中,所述指示信息中至少包括以下配置信息中的一种:
端口或M层的数量即M;
为所述M个端口或M层的上行参考信号配置的发送梳的数量N,N为整数且N≥2;
所述M个端口或M层中的一个端口或层的上行参考信号占用的发送梳的索引k,k为整数,k可以在0至系统在频域上的发送梳数量(可以大于或等于N)之间取值;

本实施例还提供了一种上行参考信号的接收处理装置,包括存储器和处理器,其中:
所述存储器设置为保存程序代码;
所述处理器设置为读取所述程序代码,执行以下的上行参考信号的接收处理:
接收基站发送的高层信令或下行控制信令,所述高层信令或下行控制信令包含所述终端发送M个端口或M层的上行参考信号所使用的资源的指示信息,M=8或16;
根据所述指示信息,确定发送所述M个端口或M层的上行参考信号所使用的资源。
本实施例中,所述处理器执行的上行参考信号的接收处理可以与本实施例上行参考信号的接收处理方法中的处理相同,在此这里不再一一赘述。
以下的实施例是上行参考信号的发送方法及相应接收处理方法的几个示例,且这些实施例主要关注资源的使用方式,基站和终端发送的步骤可参见上述实施例提供的相应方法。
本实施例中,基站在高层信令或下行控制信令中,为终端配置的端口或层(如果终端做预编码称之为层,不做预编码称之为端口)的数量可以为8,为终端配置的发送梳数量可以为2。此外,上行参考信号占用的最小发送资源块RB数可以为4(该配置信息由基站和终端双方约定),则可用的循环移位索引的数量为8。本实施例中,系统中每个资源块有12个子载波,4个资源块共48个子载波,除以发送梳的数量为2时,参考信号序列的最小长度48/2=24。而参考信号序列的最小长度是循环移位数量的整数倍,因此该序列的循环移位数量可以取6,8,12等,本实施例取8。
本实施例中,8个端口或8个层的上行参考信号使用不同的循环移位索引进行码资源(即序列)的复用,8个端口或8个层分别占用索引为0、索引为1、索引为2、索引为3、索引为4、索引为5、索引为6、索引为7的循环移位索引(例如,8个端口分别发送对根序列进行0~7个bit的循环移位后得到的上行参考信号序列)。并且,8个端口中的4个端口占用1个发送梳,另外4个端口占用另外1个发送梳。例如,占用循环移位索引为0、循环移位索引为2、循环移位索引为4、循环移位索引为6的端口使用同1个发送梳,占用循环移位索引为1、循环移位索引为3、循环移位索引为5、循环移位索引为7的端口使用同1个发送梳。
图5示出了上行系统带宽中第一层的SRS带宽,以及为每个终端(UE)所分配的带宽,每个终端占用不同的频段。图6是将SRS带宽分成两个发送梳的示意图,发送梳comb0是一个频域资源,comb1是另外一个频域资源。可以将其中的一个或两个配置给1个UE,也可以配置给多个UE。
本实施例中,基站在高层信令或下行控制信令中,为终端配置的端口或层的数量为8。上行参考信号占用的最小发送资源块RB数为8,可用的循环移位索引的数量为8或12。
在一实施例中,可用的循环移位数量可以为8或12,所述8个端口的上行参考信号分别占用索引为0、索引为1、索引为2、索引为3、索引为4、索引为5、索引为6、索引为7的循环移位;所述8个端口的上行参考信号在频域共占用2个发送梳,其中4个端口占用相同的1个发送梳,另外4个端口占用相同的另外1个发送梳;其中,占用循环移位索引为0、循环移位索引为2、循环移位索引为4、循环移位索引为6的端口使用同1个发送梳,占用循环移位索引为1、循环移位索引为3、循环移位索引为5、循环移位索引为7的端口使用同1个发送梳。

在又一实施例中,可用的循环移位数量可以为12,所述8个端口的上行参考信号使用不同的循环移位进行复用,例如,分别占用索引为0、索引为1、索引为3、索引为4、索引为6、索引为7、索引为9、索引为10的循环移位;所述8个端口的上行参考信号在频域共占用2个发送梳,其中,占用循环移位索引为0、循环移位索引为3、循环移位索引为6、循环移位索引为9的端口使用同1个发送梳,占用循环移位索引为1、循环移位索引为4、循环移位索引为7、循环移位索引为10的端口使用同1个发送梳。
使用同一发送梳的多个端口使用的序列的循环移位索引间隔大,则序列之间的正交性更好,可以达到更好的频分的效果。
本实施例中,基站在高层信令或下行控制信令中,为终端配置的端口或层的数量为8。可用的循环移位索引的数量为6或12。例如,上行参考信号的最小发送资源块RB数为4时,可用的循环移位索引的数量可以为6;上行参考信号的最小发送资源块RB数为8时,可用的循环移位索引的数量可以为6或12。

在又一实施例中,可用的循环移位数量为12,所述8端口的上行参考信号使用不同的循环移位和不同的发送梳进行复用,在频域共占用8个发送梳,每个发送梳对应端口的上行参考信号分别使用不同索引的循环移位。

本实施例涉及M个端口或M层的上行参考信号在时域上的分布。M个端口或M层的上行参考信号可以分布在1个时域符号进行发送,也可以分布在多个时域符号进行发送,
所述M个端口或M层的上行参考信号分布在多个时域符号发送时,可以采用以下两种方式之一:
方式一,在所述多个时域符号上使用相同的频域资源和码域资源,或者使用相同的参数配置。
