下面以应用示例进行说明
应用示例一
在本应用示例中,需要建立发送波束信息和测量参考信号端口之间的映射关系。
例如,上行波束训练分为两个阶段,射频波束训练阶段和数字波束训练阶段。在第一阶段通过不同的探测参考信号资源(Sounding Reference Signal resource,SRS resource)代表不同的发送波束,如图5所示。或者如图6所述,不同的发送波束通过不同的SRS resource和SRS端口表示。
第二阶段基于选择的射频波束训练上行数字波束,比如选择了波束{3,13}作为发送波束,而SRS的端口数为4,此时2个发送波束和4个SRS端口之间的映射关系需要进一步确定。
对于所述映射关系可以通过指示信息来指示或者约定下述之一:发送波束占有的SRS端口个数的比例关系,每个发送波束占有的SRS端口数,每个发送波束对应的SRS端口组,以及每个SRS端口对应的发送波束组。
如图7所示,每个发送波束以相同比例占有SRS端口。即每个发送波束占有的端口数为
Figure PCTCN2018095268-appb-000001
或者每个发送波束占有的SRS端口数为
Figure PCTCN2018095268-appb-000002
当不能整除时,后面的至少一个发送波束占有的端口数相比前面的发送波束占有的端口数多1个,即SRS端口{1,2}和发送波束3对应,即SRS端口{2,4}和 发送波束13对应,在图7中,SRS端口i在TXRUi上传输,i=1,2,3,4。
或者,如上两个发送波束{3,13},4个SRS端口,指示发送波束3占有的SRS端口数为3,发送波束13占有的SRS端口数为1。指示占有的端口数之后,具体哪个SRS端口上采用哪个发送波束由终端决定,只要满足比例关系,或者满足所述占有的端口数关系即可。
或者,比如发送波束轮询占有所述SRS端口。比如发送波束为{3,13},SRS端口数为4,4个SRS端口上的发送波束情况为(发送波束3,发送波束13,发送波束3,发送波束13)。或者SRS端口数为5,则5个SRS端口上的发送波束情况为(发送波束3,发送波束13,发送波束3,发送波束13,发送波束3)。
或者,将SRS端口进行分组,每个分组对应一个发送波束信息。
或者,将发送波束分组,每个分组对应一个参考信号端口。
对于一个SRS资源,配置N个发送波束信息和M个SRS端口个数,需要建立N个发送资源和M个SRS端口个数之间的对应关系。其中M,N为自然数。
对于发送波束信息可以通过如下至少之一表示:下行参考信号端口信息,下行参考信号端口集合信息;下行参考信号资源信息;下行参考信号对应的时域信息;下行参考信号对应的频域信息;下行参考信号对应的码域信息;下行发送波束逻辑编号;下行接收波束逻辑编号,预编码码字集合信息(其中所述预编码信息是相对于下行参考信号的接收波束的预编码信息);下行参考信号的分组信息(比如所述分组是终端反馈的下行参考信号的分组,当然所述分组也可以是基站给终端通知的对于下行参考信号的分组),下行参考信号的类型信息(其中所述下行参考信号包括如下类型:下行测量参考信号(比如CSI-RS信号),下行同步信号,下行解调参考信号),下行参考信号资源设置信息(所述参考信号资源设置可以是NR讨论中的RS resource setting),下行参考信号资源集合信息(所述参考信号资源集合可以是NR讨论中的RS resource set),下行参考信号的限制信息(MR(Measurement restrictly,MR,下行参考信号资源类型(比如类似于LTE中的Class A,ClassB,或者NR中用于P1的CSI-RS资源,用于P2的CSI-RS资源),下行参考信号关联的测量集合的类型。其中一个下行参考信号资源集合中包括至少一个CSI-RS资源,一个下行参考信号资源设置中包括至少一个下行参考信号资源集合。上行参考信号端口信息,上行参考信号端口集 合信息;上行参考信号资源信息;上行参考信号对应的时域信息;上行参考信号对应的频域信息;上行参考信号对应的码域信息;上行发送波束逻辑编号;上行接收波束逻辑编号,预编码码字集合信息(其中所述预编码信息是相对于上行参考信号的接收波束的预编码信息);上行参考信号的分组信息(比如所述分组是终端反馈的上行参考信号的分组,当然所述分组也可以是基站给终端通知的对于上行参考信号的分组),上行参考信号的类型信息(其中所述上行参考信号类型包括如下类型:上行测量参考信号(比如SRS信号),上行随机接入信号,上行解调参考信号,上行资源请求信号,上行波束恢复请求信号),上行参考信号资源设置信息(所述参考信号资源设置可以是NR讨论中的RS resource setting),上行参考信号资源集合信息(所述参考信号资源集合可以是NR讨论中的参考信号资源集(Reference Signals resource set,RS resource set))。其中一个上行参考信号资源集合中包括至少一个SRS资源,一个上行参考信号资源设置中包括至少一个上行参考信号资源集合
另一方面,第一阶段的波束训练之后,为了进行第二阶段的数字波束训练,终端需要反馈能够同时发送的第一阶段的发送波束的个数信息。比如图5中一个发送波束用一个测量参考信号资源表示,而且所述发送波束是射频波束,则终端能够同时发送的发送波束个数取决于终端的射频链路个数,此时终端给基站反馈该终端能够同时发送的发送波束个数为4。或者如图6所示,一个发送波束用一个测量参考信号资源加参考信号端口表示。
或者基站打算进行测试的波束组合,终端告知基站对于组合中的每个发送波束可以分配的测量参考信号端口最大个数。或者终端给基站反馈对于所述组合终端能否同时传输。上述实施方式中,是一个SRS资源配置中配置了N个发送波束信息和M个SRS端口。本实施例的另一种实施方式中,在上行数据传输的配置信息或者上行控制信道的配置信息中配置了N个发送波束和M个上行发送天线端口,需要采用上述类似的方法建立发送天线端口和发送波束之间的关系,其中所述发送天线等于预编码中信息中的发送天线数,或者等于终端给基站反馈的发送天线个数。
应用示例二
在实施例中,终端向基站反馈该终端能够同时发送的发送波束的个数,基站根据终端反馈的信息,分配SRS端口个数。
本应用示例的另一种实施方式中,基站给终端发送一个发送波束组合,终端给基站反馈终端能否同时发送所述发送波束组合,如果能够同时发送所述发送波束组合时,终端向基站反馈终端对于当前组合中的每个发送波束可以分配最大为多少个测量参考信号端口。基站基于终端的反馈的信息,给终端分配当前发送波束组合中每个发送波束对应的测量参考信号端口数,即可以限定基站分配的为一个发送波束组合中的一个发送波束分配的测量参考信号端口个数小于或者等于终端反馈的SRS端口个数。
当存在上下行互易性,进行上下行波束训练时,需要进一步研究,上下测量参考信号之间的关联关系,以及当需要支持传输即可以基于下行参考信号获取波束信息也可以支持基于上行参考信号获取波束信息,如何做到支持这两者的同时节省信令开销。

下面以应用示例进行说明
应用示例三
在本应用示例中,在SRS(所述第二参考信号)的配置信息中包括CSI-RS(所述第一参考信号信息)资源信息和等级信息,终端根据所述CSI-RS资源信息和等级信息,得到发送SRS所用的波束信息。采用确定的发送波束发送所述SRS。例如终端根据所述等级信息在终端接收所述CSI-RS资源的接收波束集合中,选择合适的接收波束,根据上下行互易性,根据选择的接收波束,采用对应的发送波束或者SRS端口发送所述SRS资源。
特别是互易性成立的场景下,如图12所示,当一个下行发送波束对应终端的多个接收波束,这多个接收波束是时分产生,此时所述一个接收波束也可以是一个接收波束集合,或者称为一个接收模式。如图12所示,在进行下行接收波束训练时,在终端的3个接收波束中,存在2个接收波束的性能超过预定门限。在接下来的上行接收波束训练时,如图12所示,SRS资源1中配置CSI-RS资源1,并且配置等级1,则终端采用下行接收CSI-RS资源1质量最好的发送波束发送SRS资源1。在SRS资源2中配置CSI-RS资源1,并配置等级为2,则终端采用下行行接收CSI-RS资源1质量次优的发送波束发送SRS资源2。
上述SRS资源中配置CSI-RS资源信息只是举例,也可以在SRS资源的配置信息中包括CSI-RS的如下至少之一:CSI-RS端口,下行参考信号资源设置(比如NR讨论中的resource setting),下行参考信号资源集合(比如为NR讨论中的CSI-RS resource set),其中一个下行参考信号资源集合中包括至少一个CSI-RS资源,一个下行参考信号资源设置中包括至少一个下行参考信号资源集合,参考信号的测量限制集信息。其中所述测量限制集信息类似LTE中的方法,表示对于一个测量上报限制其结果是基于所述限制集中包括的测量参考信号得到的。比如一个测量参考信号在周期发送,测量限制集限定是一个周期,则所述一个测量上报是基于一个周期得到的,而不是基于多个周期得到的平均结果。或者允许不同测量限制集上一个测量参考信号对应的发送波束和接收波束中的至少一种不同,通过不同的限制集可以允许不同的发送波束扫描和接收波束扫描中的至少一种。其中所述测量限制集是对于有测量参考信号的时域资源的限制和有测量参考信号的频域资源中的至少一种的限制。
上述配置信息是在SRS资源中配置,只是举例,类似地也可以在SRS资源集合(比如NR讨论中的探测参考信号集(SRS set))中,或者SRS资源设置中(比如NR讨论中的探测参考信号设置(SRS setting))中配置,或者在SRS资源的每个端口配置如上CSI-RS资源信息。其中一个SRS资源集合中包括至少一个SRS资源,一个SRS设置中包括至少一个SRS资源集合。
对于图12中,一个CSI-RS资源(或者CSI-RS setting,CSI-RS set)对应的终端的接收波束集合(或者接收模式)的个数(比如接收质量超于预定门限的接收波束集合个数,或者满足其他预定条件的接收波束集合个数,或者也可以称为一个CSI-RS资源对应的接收波束集合的等级总数),终端可以上报给基站,使得基站根据终端反馈的信息安排后续的上行波束训练,比如基站根据终端反馈的信息给终端分配SRS资源数,或者基站根据终端反馈的信息给终端分配SRS端口个数。或者使得基站根据终端反馈的信息安排后续的下行接收波束训练,比如接收波束训练分配的时域个数小于或者等于终端反馈的接收波束集合个数。
应用示例四
在本应用示例中,上行参考信号和下行参考信号之间存在关联,比如两个参考信号之间存在互易性的准共位置关系。或者一个参考信号的配置信息中包括另一个参考信号信息。

或者比如下行参考信号的配置信息中包括上行参考信号信息,终端根据所述上行参考信号所用的发送波束,利用上下行互易性,得到终端接收下行参考信号的接收波束,终端采用所述确定的接收波束接收所述下行参考信号。
上行参考信号的配置信息中包括下行参考信号信息,从而使得终端参照接收下行参考信号的接收方式,得到发送上行参考信号的发送方式。在上行参考信号的配置信息中配置的下行参考信号信息包括如下至少之一:下行参考信号端口信息,下行参考信号端口集合信息;下行参考信号资源信息;下行参考信号对应的时域信息;下行参考信号对应的频域信息;下行参考信号对应的码域信息;下行发送波束逻辑编号;下行接收波束逻辑编号,预编码码字集合信息 (其中所述预编码信息是相对于下行参考信号的接收波束的预编码信息);下行参考信号的分组信息(比如所述分组是终端反馈的下行参考信号的分组,当然所述分组也可以是基站给终端通知的对于下行参考信号的分组),下行参考信号的类型信息(其中所述下行参考信号包括如下类型:下行测量参考信号(比如CSI-RS信号),下行同步信号,下行解调参考信号),下行参考信号资源设置信息(所述参考信号资源设置可以是NR讨论中的RS resource setting),下行参考信号资源集合信息(所述参考信号资源集合可以是NR讨论中的RS resource set),下行参考信号的测量限制(Measurement restrictly,MR)信息,下行参考信号资源类型(比如类似于长期演进(Long Term Evolution,LTE)中的等级A(Class A),等级B(Class B),或者NR中用于P1的CSI-RS资源,用于P2的CSI-RS资源,下行参考信号关联的测量集合的类型。其中一个下行参考信号资源集合中包括至少一个CSI-RS资源,一个下行参考信号资源设置中包括至少一个下行参考信号资源集合。
上述实施方式中在一个上行参考信号资源配置信息中包括一个下行参考信号信息,也可以是对于一个上行参考信号资源中的每个端口配置一个下行参考信息,也可以是对于一个上行参考信号资源集合配置一个下行参考信号信息(比如所述上行参考信号资源集合中包括的不同参考信号资源对应不同的上行发送波束,其中上行参考信号资源集合对应的上行发送波束集合是由第一波束周围波束的不同波束构成,其中所述第一波束基于接收所述下行参考信号的接收波束,根据上下行互易性,得到的上行发送波束。),也可以是对于一个上行参考信号资源设置配置一个下行参考信号信息。其中所述下行参考信号信息包括如上所述上行参考信号信息至少之一。
类似地,本应用示例中的另一种实施方式中,下行参考信号的配置信息中包括上行参考信号信息,使得终端采用发送上行参考信号的发送波束,根据上下行互易性,得到接收下行参考信号的接收波束,采用确定的接收波束接收所下行参考信号。下行参考信号的配置信息中包括的上行参考信号信息,可以为如下至少之一:上行参考信号端口信息,上行参考信号端口集合信息;上行参考信号资源信息;上行参考信号对应的时域信息;上行参考信号对应的频域信息;上行参考信号对应的码域信息;上行发送波束逻辑编号;上行接收波束逻辑编号,预编码码字集合信息(其中所述预编码信息是相对于上行参考信号的 接收波束的预编码信息);上行参考信号的分组信息(比如所述分组是终端反馈的上行参考信号的分组,当然所述分组也可以是基站给终端通知的对于上行参考信号的分组),上行参考信号的类型信息(其中所述上行参考信号类型包括如下类型:上行测量参考信号(比如SRS信号),上行随机接入信号,上行解调参考信号,上行资源请求信号,上行波束恢复请求信号),上行参考信号资源设置信息(所述参考信号资源设置可以是NR讨论中的RS resource setting),上行参考信号资源集合信息(所述参考信号资源集合可以是NR讨论中的RS resource set)。其中一个上行参考信号资源集合中包括至少一个SRS资源,一个上行参考信号资源设置中包括至少一个上行参考信号资源集合。
类似地可以对于一个下行参考信号资源配置一个上行参考信号信息,也可以是对于一个下行行参考信号资源中的每个端口配置一个上行参考信息,也可以是对于一个下行参考信号资源集合配置一个上行参考信号信息,也可以是对于一个下行参考信号资源设置配置一个上行参考信号信息。其中所述上行参考信号信息包括如上行参考信号信息至少之一。
上述是通过配置信息,基站给终端发送控制信息,建立上行参考信号和下行参考信号之间的关联关系,本应用示例中的另一种实施方式中不是通过配置信息,而是预定上行参考信号和下行参考信号之间存在关联关系,基站不需要发送控制信息。
例如,预定上行参考信号和下行参考信号之间存在关联关系可通过如下至少之一实现:建立上行解调参考信号和下行测量参考信号之间的关联关系;建立上行解调参考信号和下行解调参考信号之间的关联关系;建立上行解调参考信号和下行同步信号之间的关联关系;建立随机接入信号和下行同步信号之间的关联关系;建立随机接入信号和下行解调参考信号之间的关联关系;建立上行测量参考信号和下行测量参考信号之间的关联关系,建立上行测量参考信号和下行解调参考信号之间的关联关系;建立上行测量参考信号和下行同步信号之间的关联关系。

本实施例讲述当上行参考信号和下行参考信号之间有关联时,参考信号的可配置范围。
当上下行之间有互易性时,SRS的配置中会配置下行参考信号(Downlink Reference Signal,DL-RS)的相关信息(比如以下信息中的至少一种:CSI-RS的相关信息,下行同步信号的相关信息,下行解调参考信号的相关信息),使得终端根据接收下行参考信号所用的接收波束,根据上下行互易性,得到发送SRS的发送波束,采用所述确定的发送波束发送所述SRS参考信号。在SRS的配置中可配置的下行参考信号的范围可以由如下获取方式。
第一种获取方式中,SRS的配置信息中CSI-RS资源(即为所述下行参考信号)的可配置反馈与终端反馈的CSI-RS资源没有关系,CSI-RS的可配置范围为基站配置的下行所有CSI-RS资源(或者可配置范围为包括用于下行波束训练的CSI-RS资源)。比如下行波束训练时,CSI-RS资源总共有16个为{0~15},SRS的配置信息中CSI-RS的资源可配置范围为{0~16},即SRS资源配置信息中,表示一个CSI-RS资源需要4比特。
第二种获取方式中,SRS的配置信息中可配置的CSI-RS资源范围与终端反馈的CSI-RS资源之间有关系,比如下行总共配置了16个CSI-RS资源为{0~15},而终端通过下行波束训练反馈{0,1,5,7}(比如反馈CRI{0,1,5,7}),即终端反馈CSI-RS资源{0,1,5,7}表示的发送波束作为候选发送波束),此时SRS的配置信息中,CSI-RS资源的可配置范围为{0,1,5,7},从而SRS配置信息中表示一个CSI-RS资源需要2比特,即建立SRS配置信息中的CSI-RS资源和终端反馈的CSI-RS资源之间的关联。即此时在SRS配置信息中2比特信息是对于{0,1,5,7}集合中信息的索引信息。或者就是根据终端反馈的信息确定可配置的CSI-RS的范围,反馈的信息包括对于CSI-RS资源和端口的分组中的至少一种,所述SRS的配置信息中是包括反馈的分组信息,或者反馈信息有关联的测量集合,根据测量集合的类型确定所述可配置的CSI-RS资源范围。
第三种获取方式中,SRS的配置信息中可配置的CSI-RS资源范围与CSI-RS资源的类型有关联,其中所述CSI-RS资源类型包括发送波束训练(比如NR中的P-2),接收波束训练(比如NR中的P-3)。比如给终端分配了CSI-RS资源0~15,其中CSI-RS资源4是对于CSI-RS资源1对应的一个发送波束的精细化基站的发送波束训练,CSI-RS资源4和CSI-RS资源1对应的终端的接收波束一样, 则所述SRS的配置信息中CSI-RS资源范围中包括CSI-RS资源4和CSI-RS资源1其中之一就可以。比如在CSI-RS的资源配置中通过其CSI-RS资源是否包含在可配置的CSI-RS资源范围内,或者根据和CSI-RS的资源关联的测量类型,确定CSI-RS资源是否包含在可配置的CSI-RS资源范围内。或者根据所述CSI-RS资源是否有信道特性参数参考信号,确定其是否包含在所述可配置范围内,比如所述CSI-RS资源没有信道特性参数参考信号,则所述CSI-RS资源包含在所述可配置范围内,否则不包括在所述CSI-RS资源类型。或者根据CSI-RS资源所在的层级,确定其是否包含在所述可配置范围内,比如通过多阶段波束训练时,CSI-RS资源之间存在层级关系。
第四种获取方式中,上面两种方案的结合方案,基站首先通过高层信令配置多个SRS资源共享的下行参考信号资源池,然后在具体一个的SRS资源中配置一个SRS资源对应的下行参考信号资源,其中所述SRS资源对应的下行参考信号资源属于所述下行参考信号资源池,或者所述SRS配置信息中用于指示下行参考信号信息的通知域的比特数根据所述下行参考信号资源池中包括的参考信号资源个数确定。采用这种方法增加基站调度灵活性的同时,减小信令开销。
类似地对于在下行参考信号的配置信息中包括上行参考信号信息,使得终端根据发送上行参考信号信息的发送波束,根据互易性,得到接收下行参考信号的接收波束,采用确定的接收波束接收所述下行参考信号。其中所述配置信息中包括的上行参考信号信息的可配置范围可以由如下获取方式确定:第一种获取方式中所述可配置范围由分配给终端的所有上行参考信号资源构成;第二种获取方式中所述可配置范围由基站分配通过控制信息分配给终端;第三种获取方式中所述可配置范围由基站分配给终端的所有SRS资源中满足预定条件的SRS资源构成,比如所述可配置范围中不包括进行上行基站接收波束训练的SRS资源。
应用示例六
在本实施例中,当上下行互易性成立的时候,在上行参考信号的配置中指示互易性使能,此时终端基于下行参考信号的最优接收波束得到发送上行信号的发送波束,所述上行参考信号的配置信息中不具体包括下行参考信号信息。
即此时上行的发送波束是基于终端反馈的最优的下行参考信号的接收波束, 根据上下行互易性,得到发送上行参考信号的发送波束。
或者此时不是基于终端反馈的最优的下行参考信号的接收波束,而且基于终端测量得到的最优的接收波束,根据上下互易性,得到发送上行参考信号的发送波束。比如所述下行参考信号是周期发送的,终端测量下行参考信号,得到接收质量最优的下行参考信号和所述下行参考信号对应的接收波束,这个下行参考信号信息终端可能还没有反馈给基站。
应用示例七
在本应用示例中,基站向终端(所述第一通信节点)发送第一控制信息,其中,所述第一控制信息中包括第一指示域,第一参考信号信息和第二参考信号信息共享所述第一指示域。其中所述第一参考信号是所述终端接收的参考信号;所述第二参考信号是所述终端发送的参考信号。所述第一控制信息是对于上行信号的控制信息,比如所述第一控制信息是分配上行数据信道的下行控制信息,可以是下行物理层动态控制信令,或者所述第一控制信息是通知上行控制信道的控制信息,例如是高层控制信令。
所述第一参考信号是下行参考信号,包括如下至少之一:下行同步信号,下行测量参考信号,下行解调参考信号。所述第二参考信号是上行参考信号,包括如下至少之一:上行随机接入前导(Preamble)信号,上行测量参考信号,上行解调参考信号,上行资源请求信号,波束恢复请求信号。
当所述第一指示域中包括的是下行参考信号信息时,终端基于其接收下行参考信号的接收波束,并根据上下行互易性,得到其发送上行信号的发送波束,其中所述接收波束和所述发送波束的波束辐射图可以一样,也可以不一样,即此时接收波束所用的波束加权值和发送波束的波束加权值可以相同也可以不同。只是终端可以根据接收波束推测出上行信号的发送波束信息。终端根据得到的发送波束,发送所述上行信号。
当所述第一指示域包括的上行参考信号信息时,终端采用其发送上行参考信号所用的发送波束(比如所述上行参考信号是终端之前发送给基站的测量参考信号,或者之前发送给基站的解调参考信号),发送所述上行信号。
在一个控制信息中,比如下行控制信息(Downlink Control Information,DCI)信息中,所述第一参考信号通知信息和所述第二参考信号通知信息共享一个比 特通知域(即所述第一指示域)。对于通知域中数值集和内容集之间的映射关系,可以通过如下至少之一确定。
第一种映射关系确定方式是,所述第一控制信息中显式通知所述联合编码域所述数值集和内容集的映射关系,其中存在多个数据值集和内容集之间的映射关系。比如所述联合编码域包括2比特。其中第一映射关系如表格1所示(所述内容集包括的上行参考信号信息),第二映射关系如表格2所示(所述内容集包括的下行参考信号信息)。此时第一控制信息中指示所述联合编码域所述数值集和所述内容集之间的对应关系是表格1所示,还是表格2所。当然表格1和表格2的映射关系只是示例,并不排除其他的映射关系。
表格1
联合编码数值 表示的内容
00 上行参考信号端口集合0
01 上行参考信号端口集合1
10 上行参考信号端口集合2
11 上行参考信号端口集合3
表格2
联合编码数值 表示的内容
00 下行参考信号端口集合0
01 下行参考信号端口集合1
10 下行参考信号端口集合2
11 下行参考信号端口集合3
第二种映射关系指示方式是,第二控制信息中通知映射关系,例如第一控制信息是物理动态控制信息,第二控制信息为高层控制信息,其中所述高层控制信息包括RRC控制信息和MAC CE控制信息中的至少一种。
第三种映射关系的确定方法是,判断是否满足预定条件,从而确定所述数值集和内容集之间的映射关系。比如所述终端是否在约定的时间区域发送过上行参考信号,比如SRS,其中所述预定的时间段是第一控制信息发送之前的预定时间段,比如所述预定时间段为所述第一控制信息之前,当在所述预定时间段中发送过SRS,则所述联合编码表格中所述内容集包括的是SRS(所述第二参考信号)信息。当终端没有发送过SRS时,所述联合编码表格中所述内容集包括的是下行参考信号(所述第一参考信号)信息。或者根据在终端侧,是否可以由其接收下行信号的接收波束信息推断出其发送信号的发送波束信息,当可以推断出时(即终端侧存在互易性时),所述联合编码表格中所述内容集包括的是下行参考信号(所述第一参考信号)信息,否则所述内容集包括的为上行参考信号信息。或者所述上行信号对应的比特数是否超过预定阈值,当所述信号的比特数不超过预定阈值时,所述联合编码表格中所述内容集包括的是下行参考信号(所述第一参考信号),否则所述联合编码表格中所述内容集包括的是上行参考信号(所述第二参考信号),例如所述上行信号为数据信道信号和控制信道信号中的至少一种。或者根据所述上行信号对应的调制编码速率(比如调制与编码策略(Modulation and Coding Scheme,MCS))是否大于预定阈值,当所述调制编码速率超过预定阈值时,所述联合编码表格中所述内容集包括的是上行参考信号(所述第二参考信号),否则所述联合编码表格中所述内容集包括的是下行参考信号(所述第一参考信号),所述上行信号为数据信道信号和控制信道信号中的至少一种。当然也不排除其他预定条件,或者根据其他参数判断所述数值集和内容集之间的映射关系。
当然上述映射关系的确定方法可以相互结合。
应用示例八
在本应用示例中,在配置下行参考信号的第一控制信息中包括第一指示域,在所述第一指示域中下行参考信号信息(所述第一参考信号信息)和所述上行参考信号信息(所述第二参考信号信息)共享第一指示域。所述第一指示域中携带所述上行参考信号和下行参考信号其中之一。
当所述第一指示域中包括的是上行参考信号信息时,终端基于其发送上行参考信号的发送波束,并根据上下行互易性,得到其接收下行信号的发送波束, 其中所述接收波束和所述发送波束的波束辐射图可以一样,也可以不一样,即此时接收波束所用的波束加权值和发送波束的波束加权值可以相同也可以不同。只是终端可以根据发送波束推测出接收下行信号的接收波束信息。终端根据得到的接收波束,接收所述下行信号。
当所述第一指示域包括的是下行参考信号信息时,终端采用其接收下行参考信号所用的接收波束(比如所述下行参考信号是基站之前发送给终端的测量参考信号,或者之前发送给终端的解调参考信号),接收所述下行信号。
应用示例九
在本应用示例中,一个上行参考信号可以和一个下行参考信号关联,终端根据接收下行参考信号的接收波束,得到发送上行参考信号的发送波束,所述上行参考信号关联的下行参考信号可以是随时间资源,或者随频域资源变化的,比如上行参考信号在时间1与下行参考信号1关联,在时间2与下行参考信号2关联。这种变化的关联可以是通过基站发送控制信息,也可以基站发送一个下行参考信号池,上行参考信号按照约定跳变准则在不同资源与所述下行参考信号池中的不同下行参考信号关联。
应用示例十
在本应用示例中,上行参考信号在一个时隙(slot)中占有多个时域符号,所述多个时域符号可以等间隔分布。或者将一个slot中的上行传输域(或者一个slot中上行参考信号可占有的上行传输域)中包括的多个时域符号分为多个梳,在资源分配中分配一个上行参考信号占有的梳索引。
如图13所示,将一个时隙中的上行传输域分为2个时域梳,控制信息指示一个上行参考信号占有的梳索引或者梳索引集合。从而使得当需要上行发送波束扫描时,终端的上行参考信号占有一个时域梳,从而可以给中终端进行波束切换留有时间。
在上行参考信号的配置信息中可以通知梳索引,也可以通知如下信息中至少之一:各个梳占有的时域资源,比如图13中各个时域资源为符号{3~13},将所述域分成的梳级别,比如所述图13中将所述时域资源{3,13}分成两个梳。其中,对于时域资源的通知可以通知起始时域符号3和结束时域符号13,或者通 知起始时域符号3和时域符号个数11,或者通知结束时域符号13和时域符号个数11。
或者在上行参考信号的配置信息中可以通知以下信息中的至少之一:所述梳的起始符号位置,结束符号位置,所述梳的两个时域符号之间的间隔的时域符号个数。对于图13中的时域第一梳通知如下信息中的至少之一:所述梳的起始符号位置3,结束符号位置13,所述梳的两个时域符号之间的间隔的时域符号个数2。
在一实施方式中,根据所述上行参考信号是否对应终端的不同发送波束,确定是否划分时域梳,或者根据终端发送波束的切换时延,确定一个时域梳中两个时域符号之间间隔的时域符号个数,或者梳级别总数。
类似地,可以将下行参考信号划分为时域梳,使得终端可以进行接收波束切换。可以根据所述下行参考信号是否对应终端的不同接收波束,确定是否划分时域梳,或者根据终端接收波束的切换时延,确定一个时域梳中两个时域符号之间间隔的时域符号个数,或者梳级别总数。
应用示例十一:
在本应用实施例中,在第一控制信息中包括第一指示域,在所述第一指示域指示参数信息,所述参数信息可以用于上行参考信号,也可以用于下行参考信号。
所述参数信息包括参考信号端口信息,参考信号所用的序列信息,以及参考信号所用的根序列信息。
应用示例十二:
在本应用实施例中,在第一控制信息中包括第一指示域,在所述第一指示域中下行参考信号信息和上行参考信号信息联合编码。
比如上行波束训练和下行波束训练联合进行波束训练,在第一控制信息中可以为物理层动态控制信息中同时通知下行参考信号信息和上行参考信号信息。
如图14所示,首先进行下行接收波束训练,根据下行接收波束训练结果进行上行发送波束训练,图14中下行接收波束训练分配3个CSI-RS资源,每个CSI-RS资源对应基站的一个发送波束,一个CSI-RS资源在一个时域符号中, 通过将所述CSI-RS占有的资源通过基于交织的频分多址(Interleaved FDMA,IFDMA)的方式或者增大子载波间隔的方式划分为多个小时间单元,比如划分为4个小时间单元,从而可以训练3*4个发送接收波束对,即3个基站发送波束,每个发送波束对应终端的4个接收波束,通过训练之后终端得到最优的1个发送接收波束对,采用最优的发送接收波束对中,根据上下行互易性,由所述最优下行发送接收波束对中的最优接收波束,得到SRS资源1的发送波束,在SRS资源1上采用确定的发送波束发送SRS资源1。
或者SRS资源1的端口数等于分配的CSI-RS资源数3,对于基站的3个发送波束中的每个发送波束得到最好的接收波束,对于SRS资源1中的3个端口,依次采用基站的发送波束1~3分别对应的下行终端接收波束,根据互易性,得到的优选发送波束{1’,2’,3’}发送所述3个SRS端口。
或者第5个符号上SRS资源数等于分配的CSI-RS资源数3,对于3个SRS资源依次采用基站的发送波束1~3分别对应的下行终端接收波束,根据互易性,得到的优选发送波束{1’,2’,3’}发送所述3个SRS资源。
或者如图15所示,CSI-RS资源数等于SRS资源数,且CSI-RS资源i对应SRS资源i,i=1,2,3,终端对于CSI-RS资源i进行下行接收波束训练,得到最好的接收波束,根据上下行互易性,由下行接收波束得到上行发送波束,采用所述上行发送波束发送SRS资源i。
应用示例十三:
在本应用示例中,在指示上行信号的控制信息中,所述控制信息中包括上行参考信号(SRS)资源索引,或者上行参考信号资源(SRS)加上行参考信号端口索引,从而指示上行信号的发送波束信息。其中所述上行信号中配置的上行资源范围不包括U-2过程对应的SRS资源,其中U-2过程是进行上行基站的接收波束训练的SRS资源。
比如给终端分配了SRS资源0~15,其中SRS资源{4~7}为进行上行基站接收波束训练的SRS资源。则上行发送波束信息的控制信息中可配置的SRS资源集合为{0~3,8~15},不包括{4~7}。当然在指示上行信号的接收波束信息的控制信息中可配置的SRS资源可以包括{4~7}。
应用示例十四:
在本应用示例中,采用专有控制信息和公共控制信息中的至少一种通知测量参考信号的相关信息。
对于触发下行测量参考信号发送的控制信息可以在上行授权(Uplink-Grant,UL-Grant)(给终端分配上行信号:包括上行数据信道和上行控制信道的控制信息中的至少一种)物理层动态控制信息(DCI)的专有DCI中,也可以在下行授权(Downlink-Grant,DL-Grant)(给终端分配下行信号的)的专有DCI中,也可以采用类似LTE中下行控制信息格式(DCI format)3/3A的方式采用组公共控制信息通知下行测量参考信号的触发信息。
类似对可以在专有UL-Grant和DL-Grant中的至少一种的专有控制信息,或者组公共控制信息去激活下行测量参考信号的发送(比如NR讨论中的半周期CSI-RS的去激活),从而终止下行测量参考信号的发送。
类似地,也可以采用专有UL-Grant和DL-Grant中的至少一种的专有控制信息,或者组公共控制信息中发送如下至少之一:下行测量触发,下行测量去激活,触发测量上报,去激活测量上报。
类似地,上行参考信号的发送,或者上行参考信号去激活信息也可以在专有UL-Grant和DL-Grant中的至少一种的专有控制信息,或者组公共控制信息中发送。
应用示例十五:
在本应用实施例中,上行参考信号和下行参考信号之间有关联,比如存在互易性之间的关联。比如有4个上行参考信号(即所述第二参考信号)资源和8个下行参考信号(即所述第一参考信号)资源。可以通过高层控制信息配置4个上行参考信号资源和8个下行参考信号资源之间的关联关系集合或者表格,如表格3所示,在所述第一控制信息中通知的是关联关系索引信息。
表格3
关系索引 关联关系
0 (1,1,2,2)

2 (1,1,1,2)
3 (5,6,1,7)
其中(1,1,2,2)表示(上行参考信号资源1对应的下行参考信号资源索引为1,上行参考信号资源2对应的下行参考信号资源索引为1,上行参考信号资源3对应的下行参考信号资源索引为2,上行参考信号资源4对应的下行参考信号资源为2),其他类似,当然表格3也只是举例,并不排除其他的关联关系集合。
