Description

传输探测参考信号的方法、终端设备和网络设备 技术领域
本申请实施例涉及无线通信领域，并且更具体地，涉及一种传输探测参考信号的方法、终端设备和网络设备。
背景技术
在长期演进(Long Term Evolution，简称“LTE”)系统中，终端会接收网络侧通过高层信令广播的小区探测参考信号(Sounding Reference Signal，简称“SRS”)子帧，SRS只能在小区SRS子帧中传输。终端需要在进行数据传输时在小区SRS子帧中对物理上行共享信道(Physical Uplink Shared Channel，简称“PUSCH”)或物理上行控制信道(Physical Uplink Control Channel，简称“PUCCH”)进行速率匹配。如果在小区SRS子帧中，终端在传输PUCCH或PUSCH的带宽和传输SRS资源的带宽上发生冲突，终端可以发送截短的PUCCH或PUSCH，将发送PUCCH或PUSCH的上行子帧的最后一个正交频分复用(Orthogonal Frequency Division Multiplexing，简称“OFDM”)符号预留用于传输SRS。
目前的SRS传输分为两种，即周期性SRS和非周期SRS。周期性SRS在网络侧预先配置的周期性资源上以一定周期持续发送，而非周期SRS通过下行控制信息(Download Control Information，简称“DCI”)来触发，终端接收到触发信令后在最近的SRS资源上进行一次SRS传输，用于传输非周期SRS的SRS资源集合由网络侧通过高层信令预先配置，且和周期性SRS的资源是独立配置的。因为非周期SRS的灵活性更强，在5G系统中非周期SRS的应用场景要比周期SRS大得多。
但是，在5G系统中，一个时隙中可能有多个用于传输SRS的OFDM符号，如果不同终端在这些OFDM符号中选择了相同的资源用于传输各自的SRS，则可能对其他终端产生很大的持续性干扰。
发明内容
本申请实施例提供了一种传输SRS的方法、终端设备和网络设备，能够降低不同终端设备的SRS信号之间的干扰。
第一方面，提供了一种传输SRS的方法，其特征在于，包括：终端设备在第一时域资源单元中确定用于发送所述终端设备的探测参考信号SRS的多个第二时域资源单元；所述终端设备根据所述终端设备的跳频图样，确定用于在所述多个第二时域资源单元上发送所述SRS的目标资源；所述终端设备根据所述目标资源，向网络设备发送所述SRS。
因此，终端设备通过自己专属的跳频图样，确定用于在多个时域资源单元上发送SRS的资源，从而使在该多个时域资源单元中传输SRS的不同终端设备之间的干扰随机化，降低了不同终端设备之间的SRS信号的干扰，也避免了终端设备之间持续的强干扰情况。
可选地，在第一方面的一种实现方式中，所述第一时域资源单元包括时隙、迷你时隙或正交频分复用OFDM符号。
可选地，在第一方面的一种实现方式中，所述第二时域资源单元包括正交频分复用OFDM符号。
具体来说，第一时域资源单元中包括多个第二时域资源单元。第二时域资源单元的长度小于第一时域资源的长度。例如，第一时域资源单元为子帧，第二时域资源单元为OFDM符号。或者，第一时域资源单元为OFDM符号，第二时域资源单元为长度小于第一时域资源单元长度的OFDM符号。
例如，第一时域资源单元的长度可以是根据第一时域资源单元中用于传输数据的子载波间隔确定的，第二时域资源单元的长度可以是根据第一时域资源单元中用于传输SRS的子载波间隔确定的。
又例如，第一时域资源单元可以为时隙，第二时域资源单元的长度是根据第一时域资源单元中用于传输数据的子载波间隔确定的。

应理解，这里不同终端设备在这多个第二时域资源单元中用于传输SRS的码资源不同，但是不同终端设备在传输各自的SRS时可以使用相同的频域资源。
可选地，在第一方面的一种实现方式中，在所述终端设备根据所述目标资源，向网络设备发送所述SRS之前，所述方法还包括：所述终端设备接收 所述网络设备发送的下行控制信息DCI，所述DCI用于指示所述终端设备发送所述SRS，所述DCI中包括所述跳频图样的信息。

可选地，该第二时域资源单元可以为OFDM符号等时域资源单元。第二时域资源单元的长度可以是以第一时域资源单元中用于传输数据的子载波间隔计算的，也可以是以第一时域资源单元中用于传输SRS的子载波间隔计算的。在5G系统中支持多个子载波间隔，用于传输数据的子载波间隔与用于传输SRS的子载波间隔可以不同。
例如，第一时域资源单元的长度可以是根据第一时域资源单元中用于传输数据的子载波间隔确定的，第二时域资源单元的长度可以是根据第一时域资源单元中用于传输SRS的子载波间隔确定的。
具体来说，第一时域资源单元中包括多个第二时域资源单元。第二时域资源单元的长度小于第一时域资源的长度。例如，第一时域资源单元为子帧，第二时域资源单元为OFDM符号。或者，第一时域资源单元为根据所述第一时域资源单元中用于传输数据的子载波间隔确定的OFDM符号，第二时域资源单元为根据第一时域资源单元中用于传输SRS的子载波间隔确定的OFDM符号。
又例如，第一时域资源单元可以为一个时隙，第二时域资源单元的长度是根据第一时域资源单元中用于传输数据的子载波间隔确定的。
可选地，终端设备在第一时域资源单元中确定用于发送终端设备的SRS的多个第二时域资源单元，包括：终端设备接收网络设备发送的下行控制信息DCI，该DCI用于指示所述第一时域资源单元中用于发送该SRS的多个第二时域资源单元。
应理解，该多个第二时域资源单元的位置和数量等信息，可以是网络设备配置的，例如通过所述DCI指示给终端的，也可以是终端设备与网络设备之间事先约定的例如协议中规定好的。
在220中，终端设备根据该终端设备的跳频图样，确定用于在多个第二时域资源单元上发送该SRS的目标资源。
具体地说，终端设备获取属于自己的跳频(hopping)图样，并根据该跳频图样在该多个第二时域资源单元中，确定用于传输自己的SRS的目标资源。该跳频图样指示了终端设备在确定用于在多个第二时域资源单元中传输该SRS的目标资源时可以使用的跳频(hopping)方式。
终端设备的跳频图样可以是网络设备确定并指示给终端设备的，也可以是终端设备与网络设备之间事先约定好的。
可选地，在终端设备根据该终端设备的跳频图样，确定该多个第二时域资源单元中用于传输该SRS的目标资源之前，该方法该包括：终端设备接收网络设备发送的DCI，该DCI用于指示终端设备发送该SRS。进一步地，该DCI中还可以携带终端设备的跳频图样。
例如，网络设备可以向终端设备发送DCI，该DCI用于指示终端设备发送该终端设备的SRS和该终端设备的跳频ID(或称为SRS ID)，终端设备接收到该DCI后，可以根据该跳频ID确定自己的跳频图样。
可选地，该目标资源包括频域资源和/或码资源。
当该目标资源为频域资源时，该终端设备确定目标资源所使用的该跳频图样为频域资源跳频图样。该频域资源跳频图样指示了终端设备在确定用于在多个第二时域资源单元中传输该SRS的频域资源时可以使用的跳频方式。
当该目标资源为码资源时，该终端设备确定目标资源所使用的该跳频图样可以为序列跳频图样或者循环移位跳频图样。该序列跳频图样指示了终端设备在确定用于在多个第二时域资源单元中传输该SRS的SRS序列的根序 列时可以使用的序列跳频方式。该循环移位跳频图样指示了终端设备在确定用于在多个第二时域资源单元中传输该SRS的SRS序列的循环移位时可以使用的循环移位跳频方式。
下面针对目标资源为频域资源或码资源这两种情况，详细地说明终端设备如何确定该多个第二时域资源单元中用于传输该SRS的目标资源。
情况1目标资源为频域资源
可选地，该目标资源包括用于传输该SRS的频域资源，该跳频图样包括频域资源跳频图样，其中，终端设备根据该终端设备的跳频图样，确定用于在多个第二时域资源单元上发送的所述SRS的目标资源，包括：
终端设备基于所述频域资源跳频图样，根据该多个第二时域资源单元中每个第二时域资源单元的索引，和该多个第二时域资源中的第一个第二时域资源单元中用于发送该SRS的频域资源的位置，确定该每个第二时域资源单元中用于发送该SRS的频域资源。
具体地说，终端设备的跳频图样表示了每个第二时域资源单元中用于发送该SRS的频域资源的位置，与，每个第二时域资源单元的索引和第一个第二时域资源单元中用于发送该SRS的频域资源的位置之间的关系。终端设备基于该频域资源跳频图样，依次根据多个第二时域资源单元中每个第二时域资源单元的索引，以及多个第二时域资源单元中的第一个第二时域资源单元中的用于传输该SRS的频域资源的位置(即终端设备在多个第二时域资源单元中的初始跳频位置)，确定每个第二时域资源单元中用于传输该SRS的频域资源的位置，从而依次获取多个第二时域资源单元中的该目标资源即用于传输该SRS的频域资源。
在本申请实施例中，频域资源一般以物理资源块(Physical Resource Block，简称“PRB”)作为单位，频域资源的位置通过PRB索引来表示，频域资源的大小通过PRB数目来表示。
举例来说，假设第一时域资源单元为时隙，第二时域资源单元为OFDM符号。终端设备可以根据从网络设备接收到的无线资源控制(Radio Resource Control，简称“RRC”)信令确定当前时隙中发送SRS所用的OFDM符号的数量M，该SRS可以在该时隙的最后M个OFDM符号中传输。终端设备根据该时隙的时隙索引，确定这M个OFDM符号中第一个OFDM符号中的用于传输SRS的频域起始位置。终端设备根据网络设备通过高层信令指示的跳 频ID，确定属于自己的频域资源跳频图样。终端设备根据该第一个OFDM符号中用于传输SRS的频域起始位置，以及该频域资源跳频图样，确定M个OFDM符号中的每个OFDM符号上用于传输SRS的频域资源的起始位置。终端设备根据该每个OFDM符号中频域资源起始位置和预设的用于传输SRS的传输带宽，确定每个OFDM符号中用于传输SRS的频域资源。最后终端设备在确定的M个OFDM符号中的该频域资源上传输该SRS。
该频域资源跳频图样例如可以为f(k)＝mod[f(0)+k×d(i)，N]，其中，f(k)为第一时域资源单元中索引为等于k的第二时域资源单元中的用于传输SRS的频域资源的起始位置(一般表示为该第二时域资源单元中用于传输SRS的起始PRB的PRB索引)，k为正整数，d(i)为基于跳频ID为i得到的跳频参数，N为所允许的最大的频域资源起始位置。
例如图3所示的基于跳频ID为i得到的跳频图样的示意图，第一时域资源单元为时隙，第二时域资源单元为OFDM符号，该时隙中的最后三个符号用于传输SRS，预设的在每个符号中传输SRS的传输带宽等于8个PRB。如果当前有两个终端设备例如图1中所示的终端设备20和终端设备30在这三个符号上传输各自的SRS。
对于终端设备20，假设f(0)＝24(即这三个OFDM符号中的第一个符号上用于传输SRS的PRB的PRB索引为24)，d(i)＝4，N＝100，那么终端设备20的频域资源跳频图样为f(k)＝mod(24+4×k，100)，k为正整数。f(0)＝24，因此多个第二时域资源单元中符号索引为0的符号上用于传输SRS的频域资源的起始位置为索引为24的PRB；符号索引为1的符号上用于传输SRS的频域资源的起始位置为索引为28的PRB；符号索引为2的符号上用于传输SRS的频域资源的起始位置为索引为32的PRB。
而对于终端设备30，假设f(0)＝40，d(i)＝12，N＝100，那么终端设备30的频域资源跳频图样为f(k)＝mod(40+12×k，100)，k为正整数。f(0)＝40，因此多个第二时域资源单元中符号索引为0的符号上用于传输SRS的频域资源的起始位置为索引为40的PRB；符号索引为1的符号上用于传输SRS的频域资源的起始位置为索引为52的PRB；符号索引为2的符号上用于传输SRS的频域资源的起始位置为索引为64的PRB。
可以看出，终端设备20和终端设备30都在第一时域资源中的多个第二时域资源单元中传输自己的SRS，但是两个终端设备所使用的跳频ID、初 始跳频位置、所允许的最大的频域起始位置的值等参数不完全相同，使得终端设备20的跳频图样和终端设备30的跳频图样不同，从而在用于传输SRS的多个第二时域资源单元中所使用的频域资源即目标资源也并不相同。
因此，终端设备之间专属的跳频图样可以实现终端设备在发送SRS的过程中的干扰随机化，降低了不同终端设备之间的SRS信号的干扰，也避免了终端设备之间持续的强干扰情况。
可选地，该目标资源包括用于传输该SRS的频域资源，该跳频图样包括频域资源跳频图样，其中，终端设备根据该终端设备的跳频图样，确定用于在多个第二时域资源单元上发送的所述SRS的目标资源，包括：
终端设备基于该频域资源跳频图样，根据该多个第二时域资源中每个第二时域资源单元的索引和第一时域资源单元的索引，确定每个第二时域资源单元中用于发送该SRS的频域资源。
具体地说，终端设备的跳频图样表示了每个第二时域资源单元中用于发送该SRS的频域资源的位置，与，每个第二时域资源单元的索引和第一时域资源单元的索引之间的关系。终端设备基于该频域资源跳频图样，依次根据多个第二时域资源单元中每个第二时域资源单元的索引和第一时域资源单元的索引，确定每个第二时域资源单元中用于传输该SRS的频域资源的位置，从而依次获取多个第二时域资源单元中的该目标资源即用于发送该SRS的频域资源。
举例来说，该频域资源跳频图样可以为f(k)＝mod[g(m)+k×d(i)，N]，其中，f(k)为第一时域资源单元中索引为k的第二时域资源单元中的目标资源的频域起始位置，k为正整数，d(i)为基于跳频ID为i时得到的跳频参数，g(m)为基于第一时域资源单元的索引m的到的频域资源位置的值，N为所允许的最大的频域资源起始位置。
在情况1中，不同终端设备确定的用于在这多个第二时域资源单元中传输SRS的频域资源不同，但是不同终端设备在传输各自的SRS时可以使用相同的码域资源例如使用相同的用于生成各自SRS序列的根序列或者循环移位。
应理解，终端设备在多个第二时域资源单元中的初始跳频位置，即多个第二时域资源单元中的第一个第二时域资源单元中的用于传输该SRS的频域资源的位置，可以是网络设备发送给终端设备的，例如网络设备向终端设 备发送携带该初始跳频位置的信息的高层信令或者用于触发SRS发送的DCI，终端设备接收网络设备发送的该高层信令或者该DCI，从而获取在多个第二时域资源单元中的初始跳频位置。
或者，终端设备也可以通过多个第一时域资源单元之间的跳频图样。确定在多个第二时域资源单元中的初始跳频位置。例如，第一时域资源单元为时隙，多个第二时域资源单元为一个时隙的最后三个OFDM符号，多个时隙之间的跳频图样可以是预先约定好的跳频图样，该跳频图样表示了每个时隙的倒数第三个符号(即最后三个符号中的第一个符号)上用于传输SRS的频域资源位置，终端设备可以根据该跳频图样直接确定在多个第二时域资源单元中的初始跳频位置。
或者，终端设备还可以根据第一时域资源单元的索引确定在多个第二时域资源单元中的初始跳频位置。
情况2目标资源为码资源
其中，可选地，该码资源包括用于生成SRS序列的根序列，和/或用于生成SRS序列的循环移位。
可选地，该目标资源包括用于生成SRS序列的根序列，该跳频图样包括序列跳频图样，其中，终端设备根据所述终端设备的跳频图样，确定用于在该多个第二时域资源单元上发送该SRS的目标资源：
终端设备基于该序列跳频图样，根据多个第二时域资源单元中每个第二时域资源单元的索引，确定每个第二时域资源单元中用于发送该SRS的SRS序列的根序列。
具体地说，终端设备的跳频图样表示了每个第二时域资源单元中用于发送该SRS的SRS序列的根序列与每个第二时域资源单元的索引之间的关系。终端设备基于该序列跳频图样，依次根据多个第二时域资源单元中每个第二时域资源单元的索引，确定每个第二时域资源单元中用于传输该SRS的SRS序列的根序列，从而依次获取多个第二时域资源单元中的该目标资源即用于传输该SRS的SRS序列的根序列。
例如，序列跳频图样可以根据预设的伪随机序列得到，索引为k的第二时域资源单元中用于传输的SRS的SRS序列的根序列ID可以基于序列跳频图样和索引k得到。例如索引为k的第二时域资源单元中用于传输SRS的SRS序列的根序列ID可以等于f(k)，即为和k有关的变量。
举例来说，假设第一时域资源单元为第一OFDM符号，第二时域资源单元为第二OFDM符号，第二OFDM符号的长度小于第一OFDM符号的长度。终端设备根据接收到的DCI确定当前时隙中用于发送非周期SRS的第一OFDM符号的索引K。终端设备根据SRS传输所使用的子载波间隔，确定索引为K的该第一OFDM符号中包括的用于传输SRS的第二OFDM符号的数量M。例如，若当前时隙的参考子载波间隔为15kHz，该非周期SRS传输所使用的子载波间隔为60kHz，则第一OFDM符号可以包括4个用于传输SRS的第二OFDM符号，即M＝4。终端设备根据预先配置的跳频ID进行序列初始化，基于伪随机序列生成序列跳频图样。终端设备根据该序列跳频图样，以及该第一OFDM符号中用于传输SRS的每个第二OFDM符号的索引，确定每个第二OFDM符号中用于传输SRS的序列的根序列ID。终端设备根据每个第二OFDM符号中用于传输SRS所使用的根序列ID生成每个第二OFDM符号的SRS序列。终端设备在网络设备配置的资源上发送基于该SRS序列生成的SRS信号。
可选地，该目标资源包括用于生成SRS序列的循环移位，该跳频图样包括循环移位跳频图样，其中，终端设备根据该终端设备的跳频图样，确定用于在该多个第二时域资源单元上发送该SRS的目标资源，包括：
终端设备基于该循环移位跳频图样，根据该多个第二时域资源单元中每个第二时域资源单元的索引，确定每个第二时域资源单元中用于发送该SRS的SRS序列的循环移位。
具体地说，终端设备的跳频图样表示了每个第二时域资源单元中用于发送该SRS的SRS序列的循环移位与每个第二时域资源单元的索引之间的关系。终端设备基于该循环移位跳频图样，依次根据多个第二时域资源单元中每个第二时域资源单元的索引，确定每个第二时域资源单元中用于传输该SRS的SRS序列的循环移位，从而依次获取多个第二时域资源单元中的该目标资源即用于传输该SRS的SRS序列的循环移位。
例如，索引为k的第二时域资源单元中传输的SRS的SRS序列的循环移位可以基于循环移位跳频图样和索引k得到。例如索引为k的第二时域资源单元中用于传输SRS的SRS序列的循环移位可以等于f(k)，即为和k有关的变量。
在情况2中，不同终端设备确定的用于在这多个第二时域资源单元中传 输SRS的码资源不同，但是不同终端设备在传输各自的SRS时可以使用相同的频域资源。
在230中，终端设备根据该目标资源，向网络设备发送该SRS。
具体地说，终端设备根据自己专属的跳频图样确定用于在多个第二时域资源单元中传输SRS的目标资源后，就可以根据该目标资源，向网络设备发送该SRS。
可选地，该目标资源为时频物理资源，终端设备可以在确定的目标资源上对数据信道进行相应的速率匹配或者打孔处理。
可选地，该目标资源为码资源，终端设备可以在确定的目标资源即该码资源上进行资源预留，例如预留相应的循环移位。
在该实施例中，终端设备通过自己专属的跳频图样，确定用于在多个时域资源单元上发送SRS的资源，从而使在该多个时域资源单元中传输SRS的不同终端设备之间的干扰随机化，降低了不同终端设备之间的SRS信号的干扰，也避免了终端设备之间持续的强干扰情况。
图4是根据本申请实施例的传输SRS的方法400性流程图。该方法400可以由网络设备来执行。如图4所示，该传输SRS的具体流程包括：

可选地，该第二时域资源单元可以为OFDM符号等时域资源单元。第二时域资源单元的长度可以是以第一时域资源单元中用于传输数据的子载波间隔计算的，也可以是以第一时域资源单元中用于传输SRS的子载波间隔计算的。在5G系统中支持多个子载波间隔，用于传输数据的子载波间隔与用于传输SRS的子载波间隔可以不同。
具体来说，第一时域资源单元中包括多个第二时域资源单元。第二时域资源单元的长度小于第一时域资源的长度。例如，第一时域资源单元为子帧，第二时域资源单元为OFDM符号。或者，第一时域资源单元为OFDM符号，第二时域资源单元为长度小于第一时域资源单元长度的OFDM符号。
