具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
参见图1，图1是本公开实施例提供的一种SRS的传输系统的结构图，如图1所示，包括用户终端11和基站12，其中，用户终端11可以是UE(User Equipment)，例如：可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，简称 PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端侧设备，需要说明的是，在本公开实施例中并不限定终端11的具体类型。上述基站12可以是5G基站(例如：gNB、5G NR NB)，需要说明的是，在本公开实施例中并不限定基站12的具体类型。
需要说明的是，上述用户终端11和基站12的具体功能将通过以下多个实施例进行具体描述。
请参见图2，图2是本公开实施例提供的一种SRS的发送方法的示意图，该方法应用于用户终端，如图2所示，包括以下步骤：
步骤201、接收基站发送的用于指示PRB bundling size的指示信息。
其中，上述PRB bundling size可以理解为PRB bundle包括的PRB的数量，例如：上述PRB bundling size可以是1个、2个、3个或者5个等大小，即一个PRB bundle可以包括1个、2个、3个或者5个等数量的PRB。优选的，上述PRB bundling size为大于1的整数，这样可以提高基站信道值估计的性能。且上述PRB bundling size可以是上述基站根据不同的场景、业务、终端特定或者信道质量等情况为上述用户终端灵活配置的，对此本公开实施例不作限定。
步骤202、在至少一个PRB bundle内所述基站发送SRS，其中，所述至少一个PRB bundle中包括PRB的个数等于所述PRB bundling size，且属于同一PRB bundle内的PRB使用相同的预编码，所述预编码为所述用户终端自行决定的预编码。
其中，上述至少一个PRB bundle可以是，将用于传输SRS的PRB按照上述PRB bundling size进行绑定(或者理解为划分)，得到的至少一个PRB bundle。即可以将用于传输SRS的PRB绑定成一个或者多个PRB bundle，步骤202在这些PRB bundle内发送SRS。上述至少一个PRB bundle中包括PRB的个数等于所述PRB bundling size可以理解为，部分或者全部PRB bundle包括的PRB的个数等于所述PRB bundling size。
上述属于同一PRB bundle内的PRB使用相同的预编码可以理解为，任一PRB bundle内的PRB使用相同的预编码，例如：PRB bundle1内所有PRB均使用预编码1发送SRS，PRB bundle2内所有PRB均使用预编码2发送SRS， PRB bundle3内所有PRB均使用预编码3发送SRS。当然，这里仅是不同PRB bundle之间使用的预编码不同进行举例，但对此不作限定，例如：不同PRB bundle使用的预编码也可以是相同的，如PRB bundle1内所有PRB均使用预编码1发送SRS，PRB bundle2内所有PRB均使用预编码2发送SRS，PRB bundle3内所有PRB均使用预编码1发送SRS。
上述预编码为所述用户终端自行决定的预编码可以理解为，每个PRB bundle内使用的预编码均由上述用户终端自行选择的，例如：所述预编码可以为从所述用户终端存储的预编码集合选择的预编码，或者从网络侧预先配置的预编码集合中选择的预编码。
其中，上述用户终端存储的预编码集合可以是用户终端预先存储的预编码集合，例如：用户终端出厂配置的预编码和/或网络侧预先配置给用户终端的预编码等等，对此本公开实施例不作限定。
由于预编码为所述用户终端自行决定的预编码，这样可以实现上行传输分集方案是透明的。另外，由于同一PRB bundle内的PRB使用相同的预编码，这样基站估计信道时，可以以PRB bundle为信道估计单位进行信道估计，即逐PRB bundle来估计信道，实现利用PRB bundle内包括的PRB联合进行信道估计，且不需要以PRB为信道估计单位进行信道估计，进而在SRS传输时，提升网络侧信道估计的性能。
需要说明的是，上述方法可以应用于5G系统，但对此不作限定，例如：还可以应用于未来的6G系统等等。
本公开实施例中，接收基站发送的用于指示PRB bundling size的指示信息；在至少一个PRB bundle内所述基站发送SRS，其中，所述至少一个PRB bundle中包括PRB的个数等于所述PRB bundling size，且属于同一PRB bundle内的PRB使用相同的预编码，所述预编码为所述用户终端自行决定的预编码。由于属于同一PRB bundle内的PRB使用相同的预编码，这样基站能够以PRB bundle为单位来估计信道，从而提高信道估计的性能。由于用户终端自行决定的预编码，也可以节约指示SRS预编码的资源开销。
请参见图3，图3是本公开实施例提供的另一种SRS的发送方法的示意图，该方法应用于用户终端，如图3所示，包括以下步骤：
步骤301、接收基站发送的用于指示PRB bundling size的指示信息。
其中，上述指示信息可以是基站在为上述用户终端配置SRS时发送的，例如：所述接收基站发送的用于指示PRB bundling size的指示信息，包括：
接收所述基站发送的SRS配置信息，所述SRS配置信息包括用于指示PRB bundling size的指示信息和所述SRS的传输位置信息。
其中，上述传输位置信息可以是表示用于传输SRS的PRB，或者可以指示上述SRS的传输时域位置等等，对此本公开实施例不作限定。
通过上述SRS配置信息可以减少信令传输开销，因为不需要通过额外信令来传输上述指示信息。当然，上述SRS配置信息还可以包括其他信息，例如：网格信息或者SRS块信息等等。
步骤302、将用于传输SRS的PRB按照所述PRB bundling size绑定成至少一个PRB bundle；其中，任一PRB bundle包括的PRB的个数为所述PRB bundling size；或者
所述至少一个PRB bundle中一个PRB bundle包括的PRB的个数小于所述PRB bundling size，其余任一PRB bundle包括的PRB的个数为所述PRB bundling size。
其中，上述用于传输SRS的PRB可以是网络侧配置给上述用户终端，例如：配置10或者20个PRB。而上述任一PRB bundle包括的PRB的个数为所述PRB bundling size可以理解为，每个PRB bundle包括的PRB的个数是相同的，例如：用于传输SRS的PRB个数可以整除上述PRB bundling size，如用于传输SRS的PRB个数为20，而上述PRB bundling size为4，则每个PRB bundle包括的PRB的个数均是4。
上述至少一个PRB bundle中一个PRB bundle包括的PRB的个数小于所述PRB bundling size，其余任一PRB bundle包括的PRB的个数为所述PRB bundling size可以理解为，至少一个PRB bundle为多个PRB bundle时，用于传输SRS的PRB无法整除PRB bundling size，例如：用于传输SRS的PRB个数为10，而上述PRB bundling size为3，则有3个PRB bundle包括的PRB的个数是3，另一个PRB bundle包括的PRB的个数是1。即对于用于传输SRS的PRB无法整除PRB bundling size的情况，则用户终端自动减小最后一部分 余数的PRB bundling size，使其PRB bundling size等于余数。
作为一种可选的实施方式，所述将用于传输SRS的PRB按照所述PRB bundling size绑定成至少一个PRB bundle之前，所述方法包括：
接收所述基站配置的网格信息；
所述将用于传输SRS的PRB按照所述PRB bundling size绑定成至少一个PRB bundle，包括：
按照所述网格信息，将用于传输SRS的PRB分割成至少两个SRS区域，并按照所述PRB bundling size将每个SRS区域绑定成至少一个PRB bundle。
其中，上述网格信息可以理解为将PRB资源划分为多个区域的信息，且该网格信息包括可以区域间隔。例如：如图4所示，将PRB索引(index)0至PRB索引(index)X划分为多个SRS区域，每个SRS区域的大小为上述区域间隔。例如：用于传输SRS的PRB如图4中的401所示，那么，用于传输SRS的PRB在本实施方式中就分割成为6个SRS区域，其中，首尾两个SRS区域大小只占部分区域间隔；又例如：用于传输SRS的PRB如图4中的402所示，那么，用于传输SRS的PRB在本实施方式中就分割成为5个SRS区域，每个SRS区域大小等于区域间隔。
另外，在分割成多个SRS区域，在每个分割开的SRS区域独立做PRB bundle。同样，对于分割开的区域无法整除PRB bundling size的情况，则用户终端自动减小最后一部分余数的PRB bundling size，使其PRB bundling size等于余数。例如，分割开的SRS区域为5个PRB，网络指示PRB bundling size等于2，则用户终端配置这个分割开的SRS区域的5个PRB做PRB bundle的大小为2个PRB，2个PRB，1个PRB，其中1个PRB等于取余(5/2)。
需要说明的是，本实施方式中，上述PRB bundling size可以小于或者等于区域间隔。
本实施方式中，通过上述网格信息可以实现为不同的用户终端分割SRS区域，且上述网格信息不需要每次配置SRS时均向用户终端发送，从而可以节约信令传输开销。另外，针对每个SRS区域单独做PRB bundle，从而可以提高PRB bundle的精确度，以提高SRS传输的性能。且还可以实现不同用户终端的用于传输SRS的PRB bundle绝大部分是对齐的，从而可以减少多用户 终端之间的干扰，提高SRS的传输性能。
另一种可选的实施方式，所述将用于传输SRS的PRB按照所述PRB bundling size绑定成至少一个PRB bundle之前，所述方法包括：
接收所述基站配置的SRS块信息；
所述将用于传输SRS的PRB按照所述PRB bundling size绑定成至少一个PRB bundling，包括：
按照所述SRS块信息，将用于传输SRS的PRB分割成至少两个SRS块(SRS block)，并按照所述PRB bundling size将每个SRS块绑定成至少一个PRB bundle。
其中，上述SRS块信息用于指示将用于传输SRS的PRB分割成至少两个SRS块，且SRS块信息可以包括各SRS块包括的PRB个数，或者包括SRS块的分割规则等，对此本公开实施例不作限定。另外，SRS块的分割可以支持非均匀分配，例如：用于传输SRS的PRB个数为10，则可以分成3个PRB的SRS块、4个PRB的SRS块和3个PRB的SRS块，也可以分成是两个5个PRB的SRS块。
需要说明的是，本实施方式中，上述PRB bundling size可以小于或者等于SRS块。
该实施方式中，针对每个SRS块单独做PRB bundle，从而可以提高PRB bundle的精确度，以提高SRS传输的性能。且由于先分割SRS块，再绑定成PRB bundle，这样可以实现不同用户终端的用于传输SRS的PRB bundle绝大部分是对齐的，从而可以减少多用户终端之间的干扰，提高SRS的传输性能。
步骤303、在至少一个PRB bundle内所述基站发送SRS，其中，属于同一PRB bundle内的PRB使用相同的预编码，所述预编码为所述用户终端自行决定的预编码。
本实施例中，通过上述步骤可以实现网络侧在配置用户终端的SRS时，同时指示PRB bundling size，这样可以解决用户终端自行决定预编码的情况下，即网络侧在没法获得信息的情况下，提高了其信道估计的性能。
请参见图5，图5是本公开实施例提供的一种SRS的接收方法的流程图，该方法应用于基站，如图5所示，包括以下步骤：
步骤501、向用户终端发送用于指示PRB bundling size的指示信息；
步骤502、在至少一个PRB bundle内接收所述用户终端发送的SRS，其中，所述至少一个PRB bundle中包括PRB的个数等于所述PRB bundling size，且属于同一PRB bundle内的PRB使用相同的预编码，所述预编码为所述用户终端自行决定的预编码；
步骤503、使用所述SRS以PRB bundle为信道估计单位进行信道估计。
可选的，所述预编码为从所述用户终端存储的预编码集合选择的预编码，或者从网络侧预先配置的预编码集合中选择的预编码。
