可选地，在一实施方式中，在本实施例中，上述存储介质可以包括但不限于：U盘、只读存储器(Read-Only Memory，简称为ROM)、随机存取存储器(Random Access Memory，简称为RAM)、移动硬盘、磁碟或者光盘等各种可以存储程序代码的介质。
本发明本申请的实施例还提供了一种处理器，该处理器用于运行程序，其中，该程序运行时执行上述任一项方法中的步骤。
可选地，在一实施方式中，本实施例中的具体示例可以参考上述实施例及可选实施方式中所描述的示例，本实施例在此不再赘述。
为更好地理解本申请实施例，以下结合优选的实施例对本申请做进一步解释。
LTE中支持周期和非周期的SRS触发方式，周期和非周期的SRS参数独立配置。非周期的SRS不支持跳频模式。在NR中由于支持一个slot中一个SRS资源可以占有多个时域符号，为了快速定位优选频带，可以考虑非周期触发的SRS也支持跳频模式，需要进一步考虑非周期触发的SRS支持跳频图样的可配置参数。以及周期跳频和非周期跳频之间的联系。
LTE中SRS所占的系统带宽，SRS的树状结构，是通过系统消息通知的，SRS所占的子帧位置是通过系统消息发送的，是Cell Specific的。通过配置Cell-Specific的SRS参数，用于PUCCH/PUSCH的速率匹配，但是这时候也造成一定的资源浪费，因为Cell-Specific配置的SRS资源可能没有任何终端占有。进一步考虑NR中可能动态通知PUSCH的时域起始位置和时域结束位置，PUCCH/PUSCH如何和SRS做速率匹配也是需要进一步考虑的问题。
NR中SRS也需要支持波束扫描，如何设计SRS图样使其适应波束扫描也是本文要考虑的问题。
总之，LTE中的SRS的发送模式，不能很好地适应NR的诸多需求，需要进一步考虑SRS的相关改进模式，使其能够适应NR的诸多需求。
本申请提供的优选实施例，可以使得参考信号适应于NR的诸多新需求，比如在基站对应的带宽远大于终端支持的带宽时，能够快速锁定终端的优选带宽，在优选带宽中实时进行更精细信道探测过程，使得参考信号的跳频方案中结合波束训练过程，参考信号的跳频方案中考虑端口组的跳变方案。
优选实施例1
相关技术的LTE中，为了支持边缘用户，或者功率受限用户，或者增加SRS的容量，上行参考信号SRS支持跳频规则，但是SRS的跳频所占有的频域的并集是连续的，不存在非连续频段。即SRS需要在跳频带宽范围内的所有频段上都发送参考信号。
具体地，如图1所示SRS的树状结构中，其中b即为频域带宽等级索引，N b即为带宽等级(即为频域带宽等级，在下文中为了简单将频域带宽等级简称为带宽等级，频域带宽简称为带宽)索引为b的带宽等级对应的频域带宽个数，或者N b也可以称为带宽等级为max(b-1，0)的等级中的一个树叶包括的等级为b的树叶的个数，其中所述树状结构为所述多级频域带宽结构中的一类。当然本申请并不排除其他的多级频域带宽结构。
当配置b hop＝0,B SRS＝3时，终端基于图2所示的跳频图样发送SRS，图2中是一个跳频周期中SRS占有的频域位置示例图，在不同的跳频周期中所述SRS占有的频域位置相对时间变化的图样是重复的、或者不同跳频周期中SRS占有的频域位置的并集是相同的。此时一个跳频周期 中，所述SRS占有的频域位置的并集占满跳频带宽，即图1中所示的b＝0的一个频域带宽为跳频带宽，如图2中方格所示一个跳频周期中所述参考信号占有的频域位置占满所述跳频带宽。此时要完成全频域探测，且终端每个时刻只能发送b＝3中的一个树叶对应的频域带宽情况下，需要8个时域符号。当SRS在一个时间单元中(比如子帧或者slot中)只占有一个时域符号时，需要8个SRS周期才能完成一次探测。对于NR中的大带宽，这样的跳频方式是不能容忍的，而且考虑到NR中基于波束传输，频选特性进一步降低，不需要全带宽跳频就可以得到优选频带，需要考虑适应于NR中的跳频模式，另一方面考虑到NR中基站支持的最大带宽远远大于终端的支持带宽，如何在在基站支持的大带宽中快速找到终端的优选带宽也是需要加速跳频速度的需求之一。
为此，可以通知参考信号在树状结构中的跳频带宽等级集合信息，在不属于所述跳频带宽等级集合的带宽等级中，所述参考信号对应的频域带宽索引信息不随时间变化(参考信号对应的频域带宽索引也可以称为参考信号占有的频域带宽索引)，在属于所述跳频带宽等级集合的带宽等级中，所述参考信号的频域带宽索引随着时间变化。
具体地，以SRS为例，SRS采用树状结构，通知b hopA(即所述跳频带宽等级集合)，比如b hopA＝{1,2}，如图10a所示，其中，图10a是根据本申请优选实施例1提供的不同带宽等级跳变的带宽索引集合不同的示例图一，图10a中的N_b类似于上述实施例中的N b，在SRS的树状结构中，在b∈b hopA＝{1,2}等级中，SRS对应的带宽索引遍历该带宽等级的所有带宽索引(其中一个带宽等级对应的所有带宽索引为该带宽等级的上一级的一个带宽对应的本级的多个带宽的索引信息)，即n 1(t)∈{0,1,...N 1-1}＝{0,1}，n 2(t)∈{0,1,...N 2-1}＝{0,1}，当
Figure PCTCN2018101605-appb-000039
其跳频带宽索引不变，如图10a所示，n 1(t)＝0，n 3(t)＝1。在图10a中虽然n 1(t)∈{0,1,...N 1-1}＝{0,1}，n 2(t)∈{0,1,...N 2-1}＝{0,1}，SRS在{1，2}带宽等级上对应的饿带宽索引遍历该跳频带宽等级的所有带宽索引，但是每次发送只发送b＝3中的一个带宽长度的SRS，即参考信号跳频所占的频域位置的并集(或者称为SRS在一个跳频周期中占有的频域位置)如图10c斜线阴影部分所示，其中，图10c是根据本申请优选实施例1提供的在图10b所示的跳频图样中参考信号跳频所占的频域位置的并集的示意图一，其中，图10b为根据本申请优选实施例1提供的基于跳频带宽等级集合进行跳频的示例图一。
进一步地端口p上的SRS的跳频图样通过如下公式确定：

Figure PCTCN2018101605-appb-000058
k TC，B SRS，n RRC，b hop都是高层配置的。具体地以图1所示的树状结构，设置b hopA＝{1,2}，B SRS＝3，采用公式(7-1)～(8-4)的跳频图样，则跳频图样如图10b所示，从而参考信号跳频所占的频域位置的并集如图10c 中的阴影部分所示，即此时参考信号跳频所占的频域位置存在非连续频段，和/或参考信号所占的频域位置小于跳频带宽(此时跳频带宽为b＝max(min(b hopA),0)＝0的带宽等级对应的一个带宽长度)，在上述设置中b hopA中的跳频等级集合是连续的，只是跳频等级集合中的最大值小于B SRS，即max(b hopA)<B SRS、当然本实施例中也不排除跳频等级集合中的跳频等级是非连续的，比如配置b hopA＝{1,3}，B SRS＝3，则SRS在每个带宽等级中所对应的带宽索引如图11a所示，其中，图11a是根据本申请优选实施例1提供的不同带宽等级跳变的带宽索引集合不同的示例图二；进一步地采用公式(7-1)～(8-4)，所述参考信号的跳频图样(即所述参考信号占有的频域随时间变化的图样)如图11b所示，其中，图11b是根据本申请优选实施例1提供的基于跳频带宽等级集合进行跳频的示例图二，此时所述参考信号在一个跳频周期中占有的频域位置如图11c的斜线阴影部分所示，其中，图11c是根据本申请优选实施例1提供的在图11b所示的跳频图样中参考信号跳频所占的频域位置的并集的示意图一。
在公式(7-1)～(7-2)中，在不属于所述跳频等级集合的等级中，所述参考信号的频域带宽索引信息不随时间变化，在属于所述跳频等级集合的等级中，所述参考信号的频域索引带宽索引随着时间变化。在本实施例的另一种实施方式中，在不属于所述跳频等级集合的等级中，所述参考信号的频域带宽索引信息随时间变化，但是所述参考信号在该带宽等级对应的频域带宽索引集合是所述频域带宽等级对应的频域带宽索引集合的真子集，在属于所述跳域带宽等级集合等级中，所述参考信号占有的频域带宽索引随着时间改变；且在属于所述频域带宽等级集合等级中，所述参考信号占有的频域带宽索引集合为所述频域带宽等级对应的频域带宽索引集合。
比如设置跳频等级集合为b hopA＝2，如图12a所示，其中，图12a是根据本申请优选实施例1提供的不同带宽等级跳变的带宽索引集合不同的示例图三，当b＝0，1的时候，n b(t)＝0，当b＝2的时候，n 2(t)∈{0,1}＝{0,1,...N 2-1}，即跳频的带宽索引集合为该带宽等级中的所有带宽索引的集合{0,1,...N 2-1}，当b＝3的时候，n 3(t)∈{0,2}∈{0,1,...N 3-1}，即跳频的带宽索引集合为该带宽等级对应的所有带宽索引的集合的真子集。即存在3种等级集合{0，1}{2}{3}，对于{0，1}带宽等级集合，参考信号所占的带宽索引是不随时间改变的固定值，{2}带宽等级中的 参考信号所占的带宽索引遍历所有的带宽索引，{3}带宽等级中参考信号所占的带宽索引是该带宽等级对应的带宽索引集合的真子集。其中所述带宽等级N对应的所有带宽索引，为带宽等级N-1中的一个带宽包括的带宽等级N中的多个带宽对应的带宽索引。其中N为大于0的整数，即将带宽等级划分为多个组，不同带宽等级组对应不同关系，其中所述关系包括如下至少之一：所述参考信号对应的频域带宽索引和时域参数之间映射关系，所述参考信号在一个频域带宽等级中对应的频域带宽索引集合和所述频域带宽等级对应的所有频域带宽索引集合之间的关系；带宽等级是否有跳频，带宽等级组的跳频顺序。

在一实施方式中，可以进一步通知每个带宽等级中所述参考信号对应的频域带宽索引集合信息，使得所述参考信号在带宽等级中就在其对应的带宽索引集合中的带宽索引指示的带宽中进行跳频，不属于带宽索引集合中的带宽不进行跳变(即在所述带宽索引指示的带宽中不传输参考信号)。
优选实施例2
在本优选实施例中，一个时域符号上发送的测量参考信号占有的频域位置存在非连续频段。如图13所示，其中，图13是根据本申请优选实施例2提供的在一个时域符号上参考信号占有非连续的频域位置的示意图。
进一步地，在跳频中，一个时域符号上发送的测量参考信号占有的频域位置存在非连续频段，如图14所示，其中，图14是根据本申请优选实施例2提供的一个时域符号上参考信号占有非连续的频域位置的一种跳频图样示例图。
其中，图13，图14所示参考信号占有的频域位置，以及参考信号的跳频图样只是示例，本实施例并不排除其他的参考信号频域位置，或者其他的参考信号跳频图样。
在一个时域符号上存在非连续的频段，一种方式是每个连续频段配置独立的参考信号资源，另一种方式是在一个参考信号资源中同时分配这些非连续频段。
具体地，以上行参考信号SRS为例，当需要触发如图15a所示的跳频图样时，其中，图15a是根据本申请优选实施例2提供的跳频过程中一个时域符号上存在多个非连续的频段的示意图一；此时在一个时域符号上，SRS占有两个频段，这两个频段还是非连续的，即此时在一个时域符号上，SRS占有两个频域带宽。两个带宽分别完成在带宽0和带宽1中的信道探测，如图15a所示，频带0中包括4个小频带，频带1中包括4个小频带，参考信号每次在一个频带中只占有一个小频带。如果继续采用多级带宽结构，即比如图15a中的带宽0，1，2对应b＝1级的一个带宽，图15a中带宽i中的一个小带宽对应b＝2级的一个大带宽。 此时可以为带宽0分配一个SRS资源1，带宽2分配SRS资源2，一个SRS资源包括一个或者多个SRS端口。分配为SRS资源1和SRS资源2配置跳频参数。但是此时SRS资源1和SRS资源2在相同的时域符号上发送，对应的SRS端口可以是相同的。比如SRS资源1和SRS资源2的其他配置参数都相同，差别就是起始跳频位置不同，即类似LTE中的n RRC不同。类似地如图15b所示，其中，图15b是根据本申请优选实施例2提供的跳频过程中一个时域符号上存在多个非连续的频段的示意图二，为带宽0和带宽2配置不同的SRS资源，这两个资源可以在相同时域符号上发送，两者之间的差别是起始跳频位置不同，即类似LTE中的n RRC不同。或者如图15c所示，其中，图15c是根据本申请优选实施例2提供的跳频过程中一个时域符号上存在多个非连续的频段的示意图三，配置3个SRS资源，为带宽0中的跳频配置SRS资源1，{带宽1，带宽2}中的跳频配置SRS资源2，为带宽3中的跳频配置SRS资源3，可以为这些SRS资源配置独立的跳频参数，可选地这些SRS资源可以共享一些参数配置，比如天线端口配置。
上述举例中是在一个时域符号上存在的多个连续频段分别配置独立的SRS资源，这多个连续频段之间是非连续的。本实施例的另一种实施方式中，在一个时域符号上存在的多个连续频段配置一个SRS资源，只是这个SRS资源对应多讨论独立的参数配置信息。比如图15a～15b中的SRS资源对应2套参数配置，15c中对应3套参数配置。
进一步地，为一个时域符号上多个连续频段配置的多个SRS资源或者多个SRS参数配置中，不同SRS资源或者不同SRS参数配置中可以包括如下参数至少之一：跳频等级集合，跳频起始等级信息，跳频结束等级信息。
优选实施例3

其中所述跳频参数集合信息携带在高层控制信令中(比如所述高层信令包括RRC信令，和/或MAC CE信令)，所述参考信号的时域跳频单位信息指所述参考信号每隔所述时域跳频单位中包括的时域符号之后进行一次跳频，在所述时域跳频单位内所述参考信号的频域位置不变。参考信号资源组的跳变和频域跳变之间的关系，端口组的跳变和频域跳变之间的关系，所述参考信号占有的起始频域位置，所述参考信号频域跳变的次数，相邻的频域跳变对应频域位置之间的频域间隔，所述参考信号占有的频域位置随时间变化的函数类型，所述参考信号在一个频域带宽等级中对应的频域带宽索引集合信息；，所述参考信号的跳频频段集合信息，所述参考信号是连续频域跳频模式还是非连续频域跳频模式；频域带宽等级分组信息，频域带宽等级组是否跳频信息，频域带宽分组信息，频域带宽组是否跳频信息，频域带宽组跳频顺序信息。
具体地，类似于LTE建立参考信号频域位置的树状结构，跳频带宽等级集合信息为实施例所述的b hopA，跳频带宽起始等级信息为类似于LTE中的b hop，或者实施例1讲述的b hopA的最小值，跳频带宽结束等级信息类似于LTE中的B SRS，或者实施例1中讲述的b hopA的最大值。参考信号在一个时域符号上占有的频域带宽等级信息类似于LTE中的B SRS，或者实施例1中讲述的B.跳频周期个数信息表示相同的频域位置参考信号发送的次数，如图2中，跳频周期个数为1，图11b，12b，14中跳频周期个数为2、所述参考信号占有的时域符号的个数信息表示当前动态触发的参考信号资源占有的时域符号个数，包括一个slot中占有的个数和占有的slot的个数，所述参考信号占有的时域符号的个数信息可以是参考信号资源级别的(即一个参考信号资源对应一个数信息，也即这个参考信号资源总共占有的时域符号个数，此时可能存在参考信号资源中的一个参考信号端口占有的时域符号个数小于参考信号资源占有的时域符号个数)，也可以是端口级别的(即一个参考信号资源中不同参考信号端口可以占有不同的时域符号个数，或者一个参考信号资源中的所有参考信号端口占有所述个数信息个时域符号，当一个时域符号上只传输参考信号资源中的部分参考信号端口时，参考信号资源占有的时域符号总个数要大于一个端口占有的时域符号个数)、所述参考信号周期信息(表示参考信号时域符号之间的周期信息，或者参考信号占有slot周期，每个slot中可以占有多个时域符号，一个slot中的不同时域符号之间不满足所述周期特性)，所述参考信号周期偏置信息，所述参考信号在一个时间单元中占有的时域符号索引信息(比如所述时间单元为slot 或者一个子帧，一个slot中占有的时域符号是连续的或者时域等间隔分布的，此时只通知起始时域符号索引和/或结束时域符号索引，或者通知起始时域符号索引和时域持续时间，和/或通知时域符号之间的间隔信息)，所述参考信号在一个时间单元中占有的时域符号个数信息，所述参考信号的时域跳频单位信息(现在LTE中的时域跳频单位是1个时域符号，即时域符号发生变化，频域就开始跳频，在NR中由于考虑接收波束训练，一个slot中可以激活多个时域符号，以及考虑可能先端口组跳，再频域跳，需要考虑每N个参考信号时域符号之间再进行频域跳频，其中N为自然数，如图16所示，其中，图16是根据本申请优选实施例3提供的时域跳频单元为2个时域符号的示意图；每2个参考信号时域符号之后，发生一次频域跳变)，参考信号对应的端口个数信息，参考信号的端口组个数信息(将一个参考信号资源中的参考信号端口进行分组，根据信号资源组中的端口个数和端口组个数信息，以及约定的规则对参考信号资源中的端口进行分组)，参考信号端口组跳变图样信息(当有多个参考信号端口组时，端口组如何跳变的相关信息)，参考信号跳频参数集合索引信息，其中所述跳频参数集合通过高层信令配置(比如RRC信令和/或MAC CE信令配置，其中高层信令中可以通知多个参考信号跳频参数集合，动态信令中进一步通知在高层信令通知的多个参考信号跳频参数集合中的选择信息，比如高层信令通知了8个跳频参数集合，动态信令进一步通知当前参考信号的跳频参数集合为这8个中的哪一个，当然高层信令通知的多个参考信号集合中的不同参考信号集合可以对应不同的参考信号资源。其中所述一个参考信号跳频参数集合中可以包括本文所述的参考信号跳频图样参数中的一个或者多个参数)。参考信号资源组的跳变和频域跳变之间的关系(比如当有多个SRS资源时，是先SRS资源跳变，再频域资源跳变，还是先频域跳变再SRS资源跳变，还是频域跳变的同时SRS资源也跳变)，端口组的跳变和频域跳变之间的关系(比如1个SRS资源包括多个天线端口，将这些天线端口分成天线端口组，需要确定天线端口组的跳变和频域跳变之间的关系，是先SRS端口组跳变，再频域资源跳变，还是先频域跳变再SRS端口组跳变，还是频域跳变的同时SRS端口组也跳变)，所述参考信号占有的起始频域位置(比如跳频时参考信号所在的起始频域位置)，所述参考信号频域跳变的次数(即参考信号频域改变的次数)，相邻的频域跳变对应频域位置之间的频域间隔(跳变的间隔，单位频域间隔的单位为一个频段，其中一个频段为如下至少之一：一个PRB，一个子带，一个带宽部分，一个分量载频对应的带宽)，所述参考信号占有的频域 位置随时间变化的函数类型(比如存在多个跳频图样函数，通过信令或者约定规则确定跳频图样函数，其中跳频图样是所述参考信号占有的频域位置随时间变化的函数)，所述参考信号在一个频域带宽等级中对应的频域带宽索引集合信息(在多级频域带宽的情况下，所述参考信号在一个频域带宽等级中对应的频域带宽索引集合为所述参考信号占有的频域带宽索引)；所述参考信号的跳频频段集合信息(比如基站给终端分配跳频频段为{频段1，频段5，频段6}，终端在分配的跳频频段集合中进行跳频)，所述参考信号是连续频域跳频模式还是非连续频域跳频模式(如图2方格所示，参考信号在一个跳频周期占有的频域位置是连续的，如图10c中的阴影部分所述，参考信号在一个跳频周期中占有的频域位置存在非连续的频段)；频域带宽等级分组信息(将频域带宽等级分为多个组，不同频域带宽等级分组对应不同的关系，其中，所述关系包括以下至少之一：所述参考信号对应的频域带宽索引和时域参数之间映射关系，所述参考信号在一个频域带宽等级中对应的频域带宽索引集合和所述频域带宽等级对应的所有频域带宽索引集合之间的关系，比如等级分组1中的带宽等级中，所述参考信号对应的带宽索引随时间改变，和/或所述参考信号对应的带宽索引为所述带宽等级对应的所有频域带宽索引集合的子集1，等级分组2中的带宽等级中，所述参考信号对应的带宽索引不随时间改变，和/或所述参考信号对应的带宽索引为所述带宽等级对应的所有频域带宽索引集合的子集2)，频域带宽等级组是否跳频信息，频域带宽分组信息(比如将第N-1带宽等级中的一个带宽包括的多个第N级带宽等级中的带宽分成多个组)，频域带宽组是否跳频信息，频域带宽组跳频顺序信息(比如跳频顺序是频域带宽组1，频域带宽组2，频域带宽组3，还是频域带宽组1，频域带宽组3，频域带宽组2，其中跳频顺序即不同带宽组的发送时间的先后顺序)。
在上述实施方式中，是在物理层动态控制信令中通知跳频相关参数信息，本实施例也不排除在物理层动态控制信令中通知如下信息至少之一:树状结构信息(类似于LTE中的C SRS，根据此参数可以建立其树状结构，比如树的等级个数，每个等级中包括的树叶个数，每个树叶对应的带宽长度信息等信息)。
上述实施方式中，是在物理层动态控制信令中通知如上信息，本实施例也不排除上述参数部分参数在物理层动态信令中通知，部分参数在高层控制信令中通通知。结合起来确定跳频参数。
LTE中高层触发的SRS配置参数和动态信令触发的SRS配置参数 是独立的，本实施例中，两者之间有些参数是共享的，或者动态信触发的SRS的参数配置需要依赖于高层配置的SRS的配置参数，比如动态信令触发的SRS占有的时域符号位置集合是高层触发的SRS占有的时域符号位置集合的子集。当同一符号上既要发送高层触发的SRS也要发送动态信令触发的SRS，丢弃高层触发的SRS，或者当只有两者之间占有的频域资源有重叠时，丢弃高层触发的SRS。如图17所示，其中，图17是根据本申请优选实施例3提供的高层触发的SRS和动态触发的SRS之间的关系示意图，所述粗侧阶段是高层触发的SRS或者之前发送的第二控制信令触发，比如周期发送，而且SRS占有的频域资源的并集存在非连续频段(如图17所示，每4个带宽中参考信号占有一个带宽)。在粗侧周期之间，基站会在两个带宽组中选择其一(其中带宽组1包括{带宽0～带宽3}，带宽组2包括{带宽4～带宽7})，动态信令触发在一个带宽组中细侧，比如在细侧阶段在其中一个带宽组中所有带宽中跳变。比如图17在第一次粗侧之后动态触发第一带宽组中跳变，第二次粗侧之后基站选择第二带宽组进行细侧。细侧阶段，对于粗侧阶段参考信号在粗侧阶段已经占有的带宽上不再发送参考信号，比如图17所示，在第一次粗侧周期之后，基站选择带宽组1，在粗侧阶段终端已经在带宽组1中的带宽0上发送了参考信号，则终端在细侧阶段只需要在带宽组0中的{带宽1～带宽3}上发送参考信号。或者起码在细测阶段，带宽组1中的起始带宽位置不是从已经发送了参考信号的带宽0开始。即动态信令触发的SRS的所占频域位置根据高层信令触发的SRS的配置参数和时域参数确定。另一方面为了减少SRS占有的时域资源，动态信令触发的SRS占有的时域资源为粗侧阶段的时域资源的子集。当有动态信令触发的SRS和高层信令(或者周期发送的SRS参考信号)碰撞时，调度周期发送的SRS。
或者粗测是高层信令配置，动态信令触发(比如半周期的SRS)，细测参数也是高层信令配置，动态信令触发，此时这两个高层配置信令之间有关联，比如两个高层配置信令之间有些参数是共享的。
或者粗测是RRC信令配置，动态信令触发(比如半周期的SRS)，细测参数是MAC CE信令配置，动态信令触发，此时这RRC信令配置和MAC CE信令配置之间，比如两个高层配置信令之间有些参数是共享的，或者MAC CE的参数配置范围取决于RRC信令的参数配置。
本优选实施例中，所述物理层动态控制信令包括在PDCCH(Physical Downlink control channel)、比如所述物理层动态控制信息包括在DCI 中。

在本优选实施例中，具体讲述参考信号端口组跳变和频域跳变之间的关系。
有如下三种模式，第一种关系是频域跳变的同时端口组也在跳变，如图18a所示，其中，图18a是根据本申请优选实施例4提供的频域跳变的同时端口组也在跳变的示意图，第二种关系是先参考信号端口组跳变，再频域跳变，如图18b所示，其中，图18b是根据本申请优选实施例4提供的先天线端口跳变再频域跳变的示意图；第三种关系是先频域跳变，再端口组跳变，如图18c所示，其中，图18c是根据本申请优选实施例4提供的先频域跳变再端口组跳变的示意图，在图18a～18c中以port0，port1示例，类似地port0，port1可以对应第一端口组和第二端口组，每个端口组中至少包括1个参考信号端口。
可以固定一种跳频关系，或者信令通知是哪一种跳变关系或者根据一个slot中参考信号资源占有的时域符号个数确定哪一种跳变关系。或者是根据参考信号占有的连续的时域符号个数确定是哪一种关系，其中所述连续的时域符号可以是在多个slot中。
具体地，当一个slot中参考信号资源占有的时域符号个数(或者参考信号占有的连续的使用符号个数)大于或者等于预定阀值，则采用第二种关系，否则采用第一种关系，比如预定阀值为端口组的个数。关系也可以称为跳变模式。
优选实施例5
本实施例中，不同的参考信号的资源跳频需要满足一定的规则，即不同参考信号资源之间的跳频满足一定的约束条件。在参考信号资源组(也可以称为参考信号资源集合，包括多个参考信号资源)中的配置信息中配置相关参数，所述参考信号资源组中的所有参考信号资源根据所述配置的参数，进行资源跳变和频域跳变；
比如参考信号资源跳变和频域跳变之间的关系，其存在如下几种跳变关系。
第一种：频域跳变的同时发送资源组也在跳变，如图19a所示，其中，图19a是根据本申请优选实施例5提供的频域跳变的同时SRS资源也跳变的示意图；
第二种：先发送资源组跳变再频域跳变，如图19b所示，其中，图 19b是根据本申请优选实施例5提供的先SRS资源组跳变，再频域跳变的示意图。
第三种：先频域跳频，再参考信号资源跳频，如图19c所示，其中，图19c是根据本申请优选实施例5提供的先频域跳变再端口组跳变的示意图；
图19a～图19b中，以发送资源1和发送资源0示例，类似地，发送资源1可以对应发送资源组1，发送资源0可以对应发送资源组0，一个发送资源组中至少包括1个发送资源，一个发送资源组中的资源同时发送，不同发送资源组中的资源分时发送。
可以固定一种跳频关系，或者信令通知是哪一种关系或者根据一个slot中参考信号资源集合占有的时域符号个数确定是哪一种关系，或者是根据参考信号占有的连续的时域符号个数确定是哪一种关系，其中所述连续的时域符号可以是在多个slot中，，其中参考信号资源集合包括所述跳变的多个参考信号资源，比如SRS resource set(或者SRS资源组)包括{SRS资源0，SRS资源1}。
具体地，当一个slot中参考信号资源集合(或者参考信号资源组)占有的时域符号个数大于或者等于预定阀值，则采用第二种关系，否则采用第一种关系，比如预定阀值为端口组的个数。关系也可以称为跳变模式。
优选实施例6
在本优选实施例中，在专有控制信令中加入树状结构信息，根据此参数可以建立其树状结构，比如树的等级个数，每个等级中包括的树叶个数，每个树叶对应的带宽长度信息等信息，类似于LTE中的C SRS。
在LTE中Cell Specific通知C SRS和SRS的周期信息和周期偏置信息，PUCCH/PUSCH当和Cell Specific的SRS资源在相同子帧时，在SRS占有的时域符号上不发送PUCCH/PUSCH，这个造成资源的浪费，因为一方面可能Cell-Specific配置的SRS资源上可能没有给任何终端分配SRS资源。NR中PUCCH/PUSCH的起始时域位置和结束时域位置中可能动态通知，所以PUCCH/PUSCH不需要避让SRS的资源，或者对于动态调度时域/频域资源的PUCCH不需要避让SRS的资源，只有周期PUCCH需要避让SRS资源。
进一步地，可以为PUSCH/PUCCH配置SRS资源池信息，或者只为周期PUCCH配置SRS资源池，所述PUCCH/PUSCH，或者周期 PUCCH，避让所述配置的SRS资源池资源。优选地所述配置的SRS资源池资源是专有控制信令中配置。
优选地避让只避让SRS占有的PRB，对应SRS所在的时域符号上没有占有的PRB不需要避让。
UE-Specific的发送的SRS资源一种方式是落在上述为PUCCH/PUSCH/周期PUCCH速率匹配的SRS资源池中，另一种方式是UE-Specific发送的SRS的资源可以在上述为PUCCH/PUSCH/周期PUCCH速率匹配的SRS资源池之外。其中SRS资源包括如下资源至少之一：SRS资源，SRS时域资源，SRS频域资源，SRS码域资源，SRS空域资源。
优选实施例7
在本优选实施例中，基站分配一个非连续频域资源组，终端将这些非连续的频域资源块看成虚拟频域资源块，组合成类似LTE中的树状结构，进行虚拟频域资源块范围内全部频域资源块的跳频，或者部分虚拟频域资源块的跳频。
在连续的虚拟频域资源块中进行频域的跳变，虚拟频域资源块到物理频域资源块有约定的映射规则。
如图20a所示，其中，图20a是根据本申请优选实施例7提供的基站挑选的优选频带集合，所述优选频带集合存在非连续频段的示意图，通过全带宽SRS的发送，或者全带宽跳变的SRS的发送，基站选择出对于一个UE来说优选的带宽集合，其中优选带宽集合中存在非连续的频段。将这些选择出的优选带宽集合中的带宽进行虚拟化编号，如图20b中的将这些虚拟化带宽组合成b＝0，1，2的3级树状结构，图20b是根据本申请优选实施例提供的终端在虚拟频域资源上进行跳频的示意图，然后采用如图20b跳频、在图20a中，虽然虚拟化带宽完成全跳频，但是这些跳变的频域范围对应的实际的物理资源带宽存在非连续频段。
本优选实施例中，所述一个频域资源块，可以是一个PRB(Physical resource block)，也可以是一个子带，或者是一个partial band、或者是一个带宽部分(类似于NR讨论中的bandwidth part，比如一个带宽部分为1MHz)，或者是一个载频分量对应的频域带宽(比如一个CC对应的频域带宽)。
优选实施例8
在本优选实施例中，发送SRS的天线端口根据SRS资源组ID，和/或天线端口组ID确定，和/或时域参数。其中天线端口组也可以称为天线端口类别，或者其他名称。
进一步地，一个SRS资源发送SRS的天线端口根据SRS资源组ID和SRS资源中天线端口个数确定。
具体地，一个SRS资源组中的不同SRS资源，采用相同的天线端口发送SRS，不同的SRS资源组可以对应不同的天线端口。比如一个SRS resource组中包括N个SRS resource，每个SRS resource包括1个或者2个SRS端口。这些SRS resource是为了波束训练，为了公平性，需要限制这些波束来自于同一个发送天线。因为同一发送波束从不同发送天线发出之后，到达接收端的性能不同。但是由于终端有多个panel是，需要对于不同panel进行波束训练，此时需要有2个SRS resource set，每个SRS resource set中的SRS resource都包括1个或者2个SRS端口，但是不同SRS resource set中的SRS resource包括的1个或者2个SRS port对应的发送天线应该来自不同的panel。
具体地如表1所示，有两个SRS resource组{SRS资源组1，SRS资源组2}，SRS资源组1中包括4个SRS resource，SRS资源组2中包括8个SRS resource每个SRS resource中包括1个SRS端口，此时SRS resource资源组和SRS天线端口之间的对应关系如表1所示。
表1
SRS资源组ID SRS port
1 10
2 11
其中SRS port 10和SRS port11是不同的天线端口。而不像LTE中包括一个SRS端口的所有SRS资源，只对应到天线端口10、具体地LTE中的天线端口管理如表2所示，在NR中需要增强为如表3或者表4所示。即此时存在多个1天线端口，也可以有多个2天线端口，表3中1天线端口有4种，2天线端口有3种，4天线端口有2种，只是示例，并不排除其他种数情况。表4中发送SRS的天线端口根据天线端口数和天线端口组索引确定。

另一方面，LTE中port10和port20～port21，port40～port43之间没有关联，留做终端实现，但是NR中波束训练阶段采用1天线端口的SRS资源，上行PMI获取阶段采用4天线端口的SRS资源，对于波束训练可以进一步限定port10是和{port40～port 41}之间有关联，比如port10是{port40～port 41}中选择，而不能组合。总之，不同天线端口数的天线端口之间有关联，即包括N个端口的SRS资源1和包括M个天线端口的SRS资源2，N小于或者等于M，或者N，M为固定组合时，N个天线端口和M个天线端口之间有关联，比如(N＝1，M＝4)之间有关联。
进一步地可以根据时间参数确定不同SRS资源之间的天线端口关系，比如相同时间上的不同SRS资源对应不同的发送天线，或者相同时间上的不同SRS资源的天线端口之间没有关联，比如不同时间上的不同SRS资源对应相同的发送天线(进一步地这些SRS资源包括在一个SRS资源组中时采用这个限定)，或者不同时间上的不同SRS资源的天线端口之间有关联(比如这些SRS资源包括在一个SRS资源组中且不同时发送时，他们之间对应相同的天线端口)。
