具体实施方式
下文中将结合附图对本申请的实施例进行说明。
图1是本申请实施例提供的一种指示方法的流程图。本实施例可适用于利用多个探测参考信号(Sounding reference signal，SRS)资源进行多次PUSCH传输的情况，本实施例可通过基站来执行。
如图1所示，本实施例提供的方法包括S120。
S120、传输探测参考信号SRS资源指示SRI信息。
SRI信息用于指示K个SRS资源组，上行信息元素集合的空间参数信息与SRS资源组的空间参数信息相对应，K为大于或等于1的整数，上行信息元素包括如下之一：PUSCH，PUSCH的多次重复传输中的一次传输。在实施例中，基站向UE指示K个SRS资源组进行M次PUSCH传输。其中，1＜K≤N SRS，N SRS为UE被配置的SRS资源的总个数。其中，PUSCH传输包括基于非码本的上行传输和码本的上行传输。在一实施例中，基于非码本的上行传输所采用的SRS资源的总个数最多为4个，即基于非码本的上行传输的情况下，N SRS的最大值为4；基于码本的上行传输所采用的SRS资源的总个数最多为2个，即基于码本的上行传输的情况下，N SRS的最大值为2。对于多次PUSCH传输，基站 可以通过发送SRI信息来指示多个SRS资源进行多次PUSCH传输，即采用SRI信息指示多个发送波束进行多次PUSCH传输，从而提供了波束的分集增益。
在一实施例中，SRI信息用于指示K个SRS资源组，即SRI信息用于指示每个SRS资源组所包括SRS资源对应的SRS资源索引。在每个SRS资源组可以包括一个或两个SRS资源，并且每个SRS资源均由一个SRS资源索引来指示。比如，N SRS的最大值为4的情况下，SRS资源索引可以为0-3，即SRS资源可以为SRS0、SRS1、SRS2或SRS3；又如，在N SRS的最大值为2，SRS资源索引可以为0-1，即SRS资源包可以为SRS0或SRS1。
在一实施例中，上行信息元素集合的空间参数信息与所述SRS资源组的空间参数信息相对应，包括：第i个上行信息元素集合的空间参数信息与第i个SRS资源组的空间参数信息相对应，i＝1,…,K。在实施例中，每个SRS资源组的空间参数信息为一个上行信息元素集合所对应的空间参数信息。其中，每个SRS资源组与不同的上行信息元素集合相对应，即采用每个上行信息元素集合的空间参数信息采用对应的一个SRS资源组进行指示。在一实施例中，一个SRS资源组可以包括一个SRS资源，也可以包括两个SRS资源，与UE所支持的最大传输层数有关。示例性地，假设UE支持的最大传输层数为1，则一个SRS资源组对应的SRS资源个数为1个；又如，假设UE支持的最大传输层数为2，则一个SRS资源组对应的SRS资源个数可以为2个。
在一实施例中，K个上行信息元素集合包括第一上行信息元素集合和第二上行信息元素集合中的至少一个；第一上行信息元素集合包括如下之一：PUSCH传输指示值小于或等于预设阈值的PUSCH传输，PUSCH传输指示值为奇数传输指示值的PUSCH传输，预设阈值为PUSCH传输指示值总个数的一半；第二上行信息元素集合包括如下之一：PUSCH传输指示值大于预设阈值的PUSCH传输，PUSCH传输指示值为偶数传输指示值的PUSCH传输。其中，传输指示值包括下述之一：传输次数，时间单元索引。在实施例中，UE进行的每次PUSCH传输是在不同时刻进行的。在一实施例中，PUSCH传输指示值可以为PUSCH传输次数，也可以为时间单元索引。其中，每个时间单元索引对应一个时间单元。比如，假设进行8次PUSCH传输，每次传输间隔为1时隙(slot)，则时间单元索引可以为0～7，传输次数分别为第1～8次，则在第2次PUSCH传输时，对应的时间单元为第2时隙，以此类推，在第8次PSCH传输时，对应的时间单元为第8时隙。
在一实施例中，假设K＝2，则SRI信息用于指示两个上行信息元素集合的空间参数信息，分别为第一上行信息元素集合和第二上行信息元素集合的空间参数信息，并且SRI信息用于指示两个SRS资源组，即每个SRS资源组对应一 个上行信息元素集合。在一实施例中，可采用传输次数来对第一上行信息元素集合和第二上行信息元素集合进行说明。假设SRI信息指示两个SRS资源组进行M次PUSCH传输，其中，第一上行信息元素集合可以包括：M次传输中的前M/2次PUSCH传输，或者，M次传输中的奇数次PUSCH传输；第二上行信息元素集合可以包括：M次传输中的后M/2次PUSCH传输，或者，M次传输中的偶数次PUSCH传输。示例性地，假设M为8，则第一上行信息元素集合包括：8次传输中的前4次PUSCH传输，或8次传输中的奇数次PUSCH传输，即第一上行信息元素集合包括：1、2、3、4次PUSCH传输，或者，1、3、5、7次PUSCH传输；对应的，第二上行信息元素集合包括：5、6、7、8次PUSCH传输，或者，2、4、6、8次PUSCH传输。
在一实施例中，空间参数信息包括以下至少之一：发送波束信息，发送波束组信息，预编码矩阵信息，传输层信息，空间关系信息，空间滤波器信息。其中，发送波束信息指的是上行信息元素集合所采用的发送波束的相关信息，即一个上行信息元素集合采用一个发送波束进行PUSCH传输；发送波束组信息指的是上行信息元素集合所采用的发送波束组的相关信息，即一个上行信息元素集合采用至少两个发送波束进行PUSCH传输；预编码矩阵信息指的是UE向基站发送的包含发送波束较好的SRS资源的矩阵信息；传输层信息指的是UE的每个传输层的相关信息，比如，传输层信息可以包括：传输层数；空间关系信息用来表征发送波束的相关信息；空间滤波器信息用来表征两个参考信号的发送波束相同与否，即若两个参考信号的空间滤波器信息相同，则发送波束的相关信息相同。
在一实施例中，SRI信息包括以下之一：SRI索引值，SRI索引值与专用解调参考信号(Dedicated deModulation Reference Signal，DMRS)索引值的联合信息。在一实施例中，可通过SRI索引值向UE指示K个SRS资源组。在一实施例中，也可通过SRI索引值与DMRS索引值的联合信息向UE指示K个SRS资源组。
在一实施例中，SRI信息用于指示K个SRS资源组，包括如下之一：
下行控制信息DCI中的SRI比特域中SRI索引值用于指示第i个上行信息元素集合对应的SRS资源组；DCI中的SRI比特域中第i个SRS资源组的SRI索引值对应第i个上行信息元素集合，i＝1,…,K。
在一实施例中，在SRI信息用于指示K个SRS资源组包括DCI中的SRI比特域中SRI索引值用于指示第i个上行信息元素集合对应的SRS资源组的情况下，即采用SRI索引值来指示K(1≤K≤N SRS)个SRS资源组的情况下，假设场景为基于非码本的PUSCH传输，并且UE支持的最大传输层数为1，且K＝2。 其中，N SRS为UE可被配置的SRS资源个数的最大值。在实施例中，基站可以通过SRI信息向UE指示两个SRS资源组进行M次PUSCH传输，并且每个SRS资源与不同的上行信息元素集合相对应。其中，不同上行信息元素集合对应于不同SRS资源组中的SRS资源。在实施例中，SRI信息的第i个SRS资源组的空间参数信息对应第i个上行信息元素集合对应的空间参数信息，即第i个上行信息元素集合的发送波束就是用于发送第i个SRS资源组的发送波束。其中，上行信息元素集合可以采用以下方式之一：第一上行信息元素集合包括M次传输中的前M/2次PUSCH传输，或者，M次传输中的奇数次PUSCH传输；对应地，第二上行信息元素集合包括M次传输中的后M/2次PUSCH传输，或者，M次传输中的偶数次PUSCH传输。
表1是本申请实施例提供的一种基于非码本PUSCH传输的SRI指示对照表。如表1所示，表1中的SRI索引值为0、1，且N SRS为2的情况，SRI索引值为是0、1和2，且N SRS为3的情况，以及SRI索引值为是0、1、2和3，且N SRS为4的这三种情况，均为R15中基于非码本的L max＝1的SRI指示对照表。在实施例中，将SRI域由原来的2比特增加至4比特，新增的SRI索引值用于指示不同上行信息元素集合对应的不同的SRS资源组，其中，SRS资源索引指的是UE所采用的SRS资源的序号。其中，SRS资源索引可以为0-3，即为SRS0、SRS1、SRS2和SRS3。在实施例中，UE可以通过不同的SRI索引值来获取不同上行信息元素集合所对应的SRS资源。例如，在M＝8，N SRS＝4时，UE接收到SRI索引值的值为6，则第一上行信息元素集合与SRS0相对应，第二上行信息元素集合与SRS3相对应，即前4次PUSCH传输与SRS0相对应，后4次PUSCH传输与SRS3相对应；或者，第1、3、5、7次PUSCH传输与SRS0相对应，第2、4、6、8次PUSCH传输与SRS3相对应。

如表1所示，在SRI索引值为6，N SRS＝4的情况下，第1个上行信息元素集合的发送波束为用于发送第1组SRS资源的发送波束，即第一上行信息元素集合的发送波束为用于发送SRS0资源的发送波束；第2个上行信息元素集合的发送波束为用于发送第2组SRS资源的发送波束，即第二上行信息元素集合的发送波束为用于发送SRS3资源的发送波束，从而提高了波束的分集增益。
在一实施例中，SRI信息用于指示K个SRS资源组，包括：DCI中的SRI比特域中SRI索引值用于指示第i个SRS资源组对应的第i个上行信息元素集合。在实施例中，SRI比特域预先对SRS资源分组。比如，假设总共有8个SRS资源，前4个SRS资源是第一组，后4个SRS资源是第二组，SRI比特域从两组SRS资源组选择，并将第一组SRS资源组对应第一上行信息元素集合，以及第二组SRS资源组对应第二上行信息元素集合。
在一实施例中，SRS资源组满足如下特征中的至少之一：不同上行信息元素集合对应于不同SRS资源组；SRS资源组与如下信息之一之间有关联：空间关系信息分组，SRS资源序号分组。在实施例中，SRS资源组与空间关系信息分组和/或SRS资源序号分组有关联。比如，可通过SRS资源组得到对应的空间关系信息，相应的，可通过空间关系信息得到对应的SRS资源组。
在一实施例中，在SRI信息包括SRI索引值的情况下，即采用SRI索引值来指示K(1≤K≤N SRS)个SRS资源组的情况下，假设场景为基于非码本的PUSCH传输，并且UE支持的最大传输层数为1，且K＝2。表2是本申请实施例提供的另一种基于非码本PUSCH传输的SRI指示对照表。如表2所示，表1中的SRI索引值为0、1，且N SRS为2的情况，SRI索引值为是0、1和2，且N SRS为3的情况，以及SRI索引值为是0、1、2和3，且N SRS为4的这三种情况，均为R15中基于非码本的L max＝1的SRI指示对照表。在实施例中，将SRI域由原来的2比特增加至3比特，新增的行数(即SRI索引值)用于指示不同上行信息元素集合使用的SRS资源来自不同的SRS资源组，其中，SRS资源组的分组方式可以采用以下方式之一：按照空间关系信息区分组，或者按照SRS资源序号分组(即按前一半SRS资源与后一半SRS资源区分)。示例性地，以按照空间关系信息区分为例，对本实施例的非码本PUSCH传输的SRI索引值指 示进行说明，假设UE被配置了4个SRS资源，同时被配置了2个空间关系信息，每个SRS资源被配置了一个空间关系信息，其中，具有相同空间关系信息的SRS资源被划分为一组。又如，以按照前一半SRS资源与后一半SRS资源区分为例，对本实施例中的非码本PUSCH传输的SRI索引值指示进行说明，假设UE被配置了4个SRS资源，分别为SRS0资源，SRS1资源，SRS2资源，SRS3资源，则SRS0资源与SRS1资源为一组，SRS2资源与SRS3资源为一组。其中，上行信息元素集合可以采用以下方式之一：第一上行信息元素集合包括M次传输中的前M/2次传输，或M次传输中的奇数次PUSCH传输；对应地，第二上行信息元素集合包括M次传输中的后M/2次传输，或M次传输中的偶数次PUSCH传输。
