Description

信号传输方法和装置
本申请要求在2018年04月16日提交中国专利局、申请号为201810340285.1的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，例如涉及一种信号传输方法和装置。
背景技术
随着生活、生产对无线通信需求的迅猛发展，无线通信系统已经从第四代的长期演进技术(Long Term Evolution，LTE)、长期演进升级技术(LTE-Advanced，LTE-A)，到现在的第五代的新无线接入技术(New Radio Access Technology，New RAT，NR，)发展和演进。而NR和LTE等通信系统中，未来更好地传输信息，需要基站或者用户获取较准确的信道状态信息(Channel State Information，CSI)，其中信道状态信息包括但不限于：信道质量指示(Channel Quality Indication，CQI)、预编码矩阵指示(Precoding Matrix Indicator，PMI)、秩指示(Rank Indicator，RI)、信道状态信息参考导频资源指示(CSI-RS resource Indicator，CRI)。为了计算CSI，需要基站或者用户发送参考信号(Reference Signal，RS)，参考信道包括但不限于信道状态信息参考信号(Channel-State Information reference signal，CSI-RS)，它包括零功率的CSI-RS(Zero Power CSI-RS，ZP CSI-RS)和非零功率的CSI-RS(Non-Zero Power CSI-RS，NZP CSI-RS)，信道状态信息干扰测量信号(Channel-State Information-Interference Measurement，CSI-IM)，探测参考信号(Sounding reference signal，SRS)，NZP CSI-RS可以用来测量信道或者干扰，CSI-RS也可以用来做跟踪，叫做跟踪参考信号(CSI-RS for Tracking，TRS)，而CSI-IM一般用来测量干扰，SRS用来进行信道估计。CSI-RS，SRS，CSI-IM等这些参考信号，在传输时又包括时域特性，其中时域特性包括但不限于非周期aperiodic、周期periodic、半持续semi-persistent特性，分别表示传输的参考信号是非周期传输的，周期传输的，或者半持续传输的。其中周期参考信号或者半持续的参考信号都会通过高层信令配置一个周期和/或时隙偏置(slot offset)信息，这两个参数可以是联合编码的(比如通过高层信令periodicityAndOffset配置，通过获取这个参数，用户就 可以知道周期或者半持续参考信号的传输周期，以及传输的时隙slot)。在通信系统中，为了节省信令开销等，可能会把多个参考信号资源分成多个集合(比如CSI-RS resource set，CSI-IM resource set，SRS resource set)，参考信号资源集合包括至少一个参考信号资源，而多个参考信号资源集合可以都来自同一个参考信号资源设置(比如CSI-RS resource setting，SRS resource setting，CSI-IM resource setting，其中CSI-IM resource setting可能和CSI-IM resource setting合并，都称为CSI-RS resource setting)来配置参数信息。
在通信系统中，为了传输数据，或者在一些高层信令，物理层信令等，将信道分成了物理下行控制信道(Physical Downlink Control Channel，PDCCH)，物理下行共享信道(Physical Downlink Shared Channel，PDSCH)，物理上行控制信道(Physical Uplink Control Channel，PUCCH)，物理上行共享信道(Physical Uplink Shared Channel，PUSCH)。为了解调这些信道，还需要用到解调参考信号(DMRS，Demodulation Reference Signal)来估计信道系数以解调数据。
在NR系统中，特别是高频段(比如大于等于6G Hz)系统，为了克服路径损耗，基站和/或终端采用了射频波束以获得波束增益。而不同的基站或终端，或者基站的不同天线面板(panel)，或者终端的天线面板在传输不同物理共享信道或者参考信号时使用的射频波束可能都不同，这就需要终端或者基站在传输或者接收信息(包括参考信号和/或物理共享信道，其中参考信号包括但不限于CSI-RS,CSI-IM,SRS，TRS，物理共享信道包括但不限于PUSCH，PDSCH)时对空间参数有相同的理解。这里的空间参数包括但不限于以下之一：射频波束、空间接收参数(Spatial Rx parameter)，传输配置指示(Transmission configuration indication，TCI)、波束索引，波束组索引、以及准共位(quasi co-location)中的部分参数信息指示。不同的参考信号或者物理共享信道可以使用不同的射频波束来发送或者接收。
在传输参考信号和/或者物理共享信道的时候，相关技术还存在一些缺陷，比如，在通知非周期的CSI-IM或非周期的TRS的时域特性时还存在一定的问题，使得终端不能很好地接收所述的参考信号。另外，在传参考信号时，如果参考信号和物理共享信道有资源重叠，如何有效地接收在共同的时域资源传输的参考信号和物理共享信道，也没有很好地解决。

下面结合示例性的实施场景进行说明。
实施例1
通过本实施例用于说明在非周期参考信号，如CSI-IM(aperiodic CSI-IM，AP CSI-IM)的发送过程的时隙确定问题，基站和终端通过如下的过程发送和接收AP CSI-IM。这里，可以通过高层信令配置大于等于1个CSI-RS resource setting，每个CSI-RS resource setting包括大于等于1个CSI-IM resource set，而每个CSI-IM resource set包括大于等于1个CSI-IM resource。这里的CSI-IM的时域特性可以通过高层信令配置为周期的，非周期的，以及半持续的。
基站配置第一信令，根据第一信令确定用于发送非周期参考信号的时隙slot，在所述时隙发送非周期的信道状态信息干扰测量资源AP CSI-IM resource(s)。
在一实施例中，基站发送所述第一信令。
其中，第一信令为高层信令，包括但不限于至少以下信息之一：周期Periodicity，时隙偏置slot offset，周期和时隙偏置的联合信息periodicityAndOffset。
这里，基站也可以在所述发送参考信号的时隙发送非周期的信道状态信息干扰测量资源集合AP CSI-IM resource set(s)，非周期的跟踪参考信号资源TRS resource，非周期的跟踪参考信号资源集合TRS resource set。
在一实施例中，这里的第一信令主要用于指示周期的CSI-IM resource或者周期的CSI-IM set的周期和/或slot offset。
在一实施例中，基站配置触发信令，基站发送所述触发信令，所述触发信令为物理层信令或高层信令。
基站根据所述第一信令和所述触发信令确定发送参考信号的时隙为K+n，其中，所述K为传输触发信令的时隙，所述n为根据第一信令确定的时隙偏置，K和n为大于等于0的整数。
终端接收第一信令，根据第一信令确定接收非周期参考信号的时隙slot，在所述时隙接收非周期的信道状态信息干扰测量资源AP CSI-IM resource(s)。
在一实施例中，基站接受触发信令，所述触发信令为物理层信令或高层信令。
当然这里的，也可以在所述时隙接收非周期的信道状态信息干扰测量资源集合AP CSI-IM resource set(s)，非周期的跟踪参考信号资源TRS resource，非周期的跟踪参考信号资源集合TRS resource set。
其中，第一信令为高层信令，包括至少以下信息之一：周期(Periodicity)，时隙偏置(slot offset)，周期和时隙偏置的联合信息(periodicityAndOffset)。
在一实施例中，这里的第一信令主要用于指示周期的CSI-IM resource或者周期的CSI-IM set的周期和/或slot offset。
在一实施例中，通过第一信令为时隙偏置，终端通过所述的时间偏置确定接收AP CSI-IM resource(s)或AP CSI-IM resource set(s)的n，其中，n为非负整数。
在一实施例中，通过第一信令为周期和时隙的联合信息periodicityAndOffset，终端通过解码periodicityAndOffset获取时隙偏置部分的信息，并用获取的时隙偏置部分的信息确定接收AP CSI-IM resource(s)或AP CSI-IM resource set(s)的时隙偏置n，其中，n为非负整数。
终端根据所述第一信令确定所述时隙偏置n和所述的触发信令确定发送参考信号的时隙为K+n，所述K为传输触发信令的时隙，所述n为根据第一信令确定的时隙偏置，K和n为大于等于0的整数。
通过本实施例的方法，无线通信系统可以在不增加新的非周期CSI-IM的高层信令的情况下，即不需要修改标准的情况下，利用相关的周期CSI-IM的相关信令(周期和时隙偏置信令，比如，periodicity And Offset)达到正常发送或接收AP CSI-IM resource或AP CSI-IM resource set的目的。
当然，由于周期CSI-IM的周期和时隙偏置信令可能是针对每个CSI-IM resource的，而非周期的CSI-IM resource传输可能是针对CSI-IM resource set的，而每个CSI-IM resource set包括至少一个CSI-IM resource。所以可能存在的情况是，同一个CSI-IM resource set的不同CSI-IM resource的时隙偏置是不同的。即，非周期的信道状态信息干扰测量资源集合中的信道状态信息干扰测量资源的时隙偏置或时隙可取不同的值。当然，一个特例是它们都取相同的值，即非周期的信道状态信息干扰测量资源集合中的信道状态信息干扰测量资源的时隙偏置或时隙都相同。
本实施例也同样适用于其它的非周期参考信号，比如非周期的ZP CSI-RS，非周期的TRS等，只要将实施例中的CSI-IM替换成ZP CSI-RS或者TRS就可 以。
一个应用示例为：
基站配置周期信道状态信息干扰测量资源的周期和时隙偏置信令。配置并发送触发信令，在所述周期信道状态信息干扰测量资源的周期和时隙偏置信令确定时隙偏置n；根据时隙偏置n以及传输触发信令的时隙K确定发送非周期的信道状态信息干扰测量资源或信道状态信息干扰测量资源集合的时隙为K+n。其中，n和K为非负整数。
终端接收周期信道状态信息干扰测量资源的周期和时隙偏置信令，根据周期信道状态信息干扰测量资源的周期和时隙偏置信令确定用于接收非周期信道状态信息干扰测量资源或信道状态信息干扰测量资源集合的时隙偏置n，接收触发信令，并根据接收触发信令的时隙K确定发送参考信号的时隙为K+n，其中，n和K为非负整数。在所述时隙K+n接收非周期信道状态信息干扰测量资源或信道状态信息干扰测量资源集合。
实施例2
本实施例主要用于说明在载波聚合传输信息时，传输非周期的参考信号的过程。基站配置了多个服务小区(或载波，或BWP)CCi，第i个载波(或载波，或BWP)CCi对应的子载波间距subcarrier spacing为SCSi，i＝1,…,N，N为大于1的整数。需要说明的是，这里的服务小区，可以替换成载波或BWP。用一个物理下行控制信息(Donwlink Control information，DCI，一般由PDCCH携带)跨载波触发多个载波的参考信号，如CSI-RS，假设基站没有配置准共位置类型D(QCL Type D)。下面的过程，通过一个DCI触发多个分量载波(Component Carrier，CC)的CSI-RS resource或者CSI-RS resource set或者CSI-RS resource Setting。
配置第一信令；根据第一信令确定用于发送N个服务小区上的非周期信道状态信息参考信号(AP CSI-RS)的第一参考时间Ki，i＝1，…，N。
在一实施例中，基站发送所述第一信令。
这里，例如第一信令可以为物理下行控制信息DCI。
这里，在一实施例中，AP CSI-RS也可以是以下参考信号之一：非周期信道状态信息参考信号资源集合(AP CSI-RS resource set)，非周期信道状态信息参考信号资源设置(AP CSI-RS resource setting)，半持续的信道状态信息参考信号(SP CSI-RS)，半持续的信道状态信息参考信号资源集合(SP CSI-RS resource  set)，半持续的信道状态信息参考信号资源设置(SP CSI-RS resource setting)，非周期跟踪参考信号资源(AP TRS resource)，非周期跟踪参考信号资源集合(AP TRS resource set)，非周期跟踪参考信号资源设置(AP TRS resource setting)，非周期探测参考信号资源(AP SRS resource)，非周期探测参考信号资源集合(AP SRS resource set)，非周期探测参考信号资源设置(AP SRS resource setting)等。
这里，在一实施例中，第i个服务小区上的发送非周期信道状态信息参考信号(AP CSI-RS)的第一参考时间Ki为不早于时间T的最小时隙或不早于时间T所在的时隙或不早于时间T的最小符号，其中，所述时间T为传输服务小区触发信令的时域资源的最后一个符号，i＝1，…，N。
配置偏置信令，所述偏置信令为高层信令或者物理层信令。所述偏置信令包括发送参考信号的时隙偏置n，n为非负整数。
这里，一个应用例子如下，不失一般性，以3个服务小区为例，服务小区1(CC1)为15K的载波间距，服务小区2(CC2)为60K的载波间距，服务小区3(CC3)为120K的载波间距。那么至少存在以下的方式一直来确定每个服务小区发送参考信号的时隙，这里的第一信令为下行控制信息DCI。有可能存在如下三种情况。
情况1：DCI在载波间距最小的CC传输，比如在CC1传输，由于一般来说，DCI一般在slot的前1～3个符号传输，假设传输DCI的控制资源集合(Control-resource set，CORESET)最后一个符号为T＝2个符号；那么T＝2对应CC2的符号为第四个符号，而CC3的第8个符号，它们都属于第一个slot，所以每个服务小区都在不迟于T的最小的slot都为K1＝K2＝K3＝1，即确定在Ki+n个时隙发送第i个服务小区上的AP CSI-RS，Ki为第i个服务小区发送参考信号的第一参考时间i＝1,2,3。这里n对应的时隙slot为每个服务小区上对应的slot，比如n＝4，那么第i个服务小区发送参考信号的slot都是5，i＝1,2,3。
情况2：DCI在载波间距最大的CC传输，比如在CC3传输，由于一般来说，假设在CC3的第8个slot的第二个符号T＝2传输。那么CC3的第8个slot的T＝2对应CC1的符号为第ceil(7*14+2)/16)符号(即第7个符号，第一个slot)，而相当于CC2的第ceil(7*14+2)/4)个符号(即第25个符号，第二个slot)，从而CC1和CC2，CC3的第一参考时间分别在K1＝1，K2＝2，K3＝8，那么第一个服务小区在第n+1个slot发送AP CSI-RS，第二个服务小区在第n+2个slot发送AP CSI-RS，第三个服务小区在第n+8个slot发送AP CSI-RS。
情况3：DCI在载波间距中间的CC传输，比如在CC2传输，由于一般来说，假设在CC2的第3个slot的第二个符号T＝2传输。那么CC2的第3个slot的T＝2对应CC1的符号为第ceil(2*14+2)/4)符号(即第8个符号，第一个slot)，而相当于CC2的第ceil(2*14+2)*4)个符号(即第120个符号，第9个slot)，从而CC1和CC2，CC3的第一参考时间分别为K 1＝1,K2＝3,K3＝9,那么第一个服务小区在第n+1个slot发送AP CSI-RS，第二个服务小区在第n+3个slot发送AP CSI-RS，第三个服务小区在第n+9个slot发送AP CSI-RS。
终端接收第一信令；根据第一信令确定用于接收N个服务小区上的非周期信道状态信息参考信号(AP CSI-RS)的时隙。
这里，例如第一信令可以为物理下行控制信息DCI。
如图2所示，为根据本实施例提供的信号传输方法的信令示意图，其中两个载波CC0和CC1，通过DCI指示发送CSI-RS的时隙，对于载波CC0来说，CSI-RS和DCI在同一个时隙发送，对于载波CC1，CSI-RS在DCI之后的一个时隙发送，在哪个时隙发，需要根据CC0的传输DCI所在的时域资源的最后一个符号确定。
这里，在一实施例中，AP CSI-RS也可以是以下参考信号之一：AP CSI-RS resource set，AP CSI-RS resource setting，半持续的信道状态信息参考信号(SP CSI-RS)，SP CSI-RS resource set，SP CSI-RS resource setting，AP TRS resource，AP TRS resource set，AP TRS resource setting，AP SRS resource，AP SRS resource set，以及AP SRS resource setting等。
这里，在一实施例中，根据第一信令确定接收第i个CC的AP CSI-RS的第一参考时间Ki,i＝1,…,N，N为大于1的整数。
这里，在一实施例中，N个服务小区上的接收非周期信道状态信息参考信号(AP CSI-RS)的第一参考时间都为不迟于时间T所对应的最小时隙，其中，所述时间T为接收或传输所述第一信令的时域资源的最后一个符号。
接收偏置信令，所述偏置信令为高层信令或者物理层信令。所述偏置信令包括接收参考信号的时隙偏置n，n为非负整数。
在所述确定的N个时隙分别接收N个服务小区上的非周期的信道状态信息参考信号，其中N为大于1的整数。即在Ki+n时隙接收第i个CC的非周期信道状态信息参考信号，i＝1,…,N，N为大于1的整数。
本实施例的所述的第i个服务小区上用于发送参考信号的时隙Ki+n时隙为 对应载波间距下的时隙。
本实施例的所述的第i个服务小区上的时隙偏置n为基于第i个服务小区上的numerology定义的。比如本实施例的第i个服务小区的一个slot的时隙长为1/(2^Ni)毫秒，Ni在CC1，CC2，CC3中分别为1,4,8，及numerology的取值。分别对应不同的载波间距为2^Ni*15K，其中，i＝1,2,3，^表示指数。
需要说明的是，有一种场景是，跨服务小区触发的情况下，每个服务小区(serving cell)对应的numerology相同或者子载波间距相同，即跨服务小区触发参考信号，所述N个服务小区的numerology相同或者子载波间距相同。
实施例3
在本实施例中，发送或者接收非周期的跟踪参考信号(AP TRS)。其中，所述AP TRS分成两部分，AP TRS第一部分和AP TRS第二部分，AP TRS第一部分和AP TRS第二部分可以携带相同的信息，包括但不限于以下之一，相同的端口数，相同的时域位置，子载波位置，相同的发送功率。且AP TRS第一部分和AP TRS第二部分分别在两个连续的时隙发送。
基站配置第一信令；根据第一信令确定用于发送非周期跟踪参考信号的时隙。
在一实施例中，基站发送所述第一信令。
基站在所述第一信令确定的所述时隙发送非周期的跟踪参考信号。
在一实施例中，基站根据第一信令确定用于传输TRS的两个时隙的第一个时隙K+n，其中，K为发送第一信令资源所在的时隙，n为相对于发送非周期跟踪参考信号的第一部分的时隙或时隙偏置。在一实施例中，基站配置偏置信令，所述偏置信令包括所述的时隙偏置n，n为非负整数。
在一实施例中，根据第一信令确定用于发送非周期跟踪参考信号第一部分的时隙，其中，所述发送非周期跟踪参考信号第一部分的时隙用于发送非周期跟踪参考信号的第一部分。
比如，基站确定的用于发送非周期TRS第一部分时隙为K+n时隙，其中，K为传输第一信令资源所在的时隙，n为相对于发送非周期跟踪参考信号的第一部分的时隙或时隙偏置。一般来说，用两个时隙传输TRS，即在K+n时隙传输第一组TRS资源，在K+n+1时隙传输第二组TRS资源。
终端接收第一信令；根据第一信令确定用于接收非周期跟踪参考信号的时隙。
终端在所述时隙接收非周期的跟踪参考信号。
在一实施例中，终端根据第一信令确定用于接收TRS的两个时隙的第一个时隙K+n，其中，K为接收第一信令资源所在的时隙，n为相对于接收非周期跟踪参考信号的第一部分时隙的时隙偏置。在一实施例中，终端接收偏置信令，所述偏置信令包括所述的时隙偏置n，n为非负整数。
在一实施例中，根据第一信令确定用于接收非周期跟踪参考信号第一部分的时隙。
比如，终端确定的接收TRS第一部分的时隙为K+n时隙，其中，K为传输第一信令资源所在的时隙，n为接收跟踪参考信号的第一个时隙的时隙偏置或时隙。一般来说，用两个时隙接收TRS，即在T+n时隙接收第一组TRS资源，在T+n+1时隙接收第二组TRS资源。
如图3所示，为根据本实施例提供的信号传输方法的信令示意图，其中，用两个slot传输AP TRS，其中第一个slot参数AP TRS的第一部分，第二个slot传输AP TRS的第二部分，slot offset是相对于图中的第一个slot确定的。
实施例4
本实施例重要用于说明在多个带宽部分(bandwidth part，BWP，即用于传输资源的物理资源块集合，一般包括多个连续的物理资源块，其中每个物理资源块包括多个子载波和多个时域符号，也可以称为部分带宽)切换时参考信号的发送和接收方法。这里不失一般性，假设系统配置了N个BWP，其中第i个BWP为BWPi，i＝1,…,N，N为大于1的整数。不失去一般性，把传输第一信令的BWP记为BWP0，把需要切换的BWP成为BWP1。
