图1为本发明一实施例提供的一种上行信号的传输方法的流程示意图，如图1所示。
101、接收网络设备发送的零功率的上行参考信号(Zero-Power Uplink Reference Signal，ZP ULRS)的配置信息。
102、根据所述配置信息，确定所述ZP ULRS所占用的资源。
103、在所述资源上，不发送上行数据；和/或，在所述资源上，不发送非零功率的上行参考信号(Non-Zero-Power Uplink Reference Signal，NZP ULRS)。
在103中，在所述资源上，不发送上行数据，具体可以为：在所述资源上，对上行数据进行速率匹配或打孔处理。
需要说明的是，101～103的执行主体可以为终端。
本实施例的主要思想就是，通过网络设备的配置和向终端指示，激活零功率的上行参考信号，可以在一些终端传输上行参考信号(即非零功率的上行参考信号)时，同时指示其他终端在相应的资源上进行资源空闲，从而避免其他终端所传输的上行参考信号的干扰，提高这些上行参考信号的传输性能。
这样，通过接收网络设备发送的零功率的上行参考信号的配置信息，进而根据所述配置信息，确定所述零功率的上行参考信号所占用的资源，使得能够在所述资源上，不发送上行数据，和/或，在所述资源上，不发送非零功率的上行参考信号，由于终端进行了资源预留，有效地避免了终端在所预留的资源上传输的上行信号对其他终端在所预留的资源上传输的上行参考信号所造成的干扰，能够保证终端的上行参考信号的可靠传输，从而提高了这些上行参考信号的传输性能。
可选地，在本实施例的一个可能的实现方式中，所述ZP ULRS可以包括但不限于ZP SRS、ZP DMRS或ZP PTRS这些现有的ULRS， 或者还可以为NR***新定义的其他ZP ULRS，本实施例对此不进行特别限定。
可选地，在本实施例的一个可能的实现方式中，所述NZP ULRS可以包括但不限于NZP SRS、NZP DMRS或NZP PTRS，或者还可以为NR***新定义的其他NZP ULRS，本实施例对此不进行特别限定。
可选地，在本实施例的一个可能的实现方式中，在101中，具体可以接收网络设备通过高层信令或下行控制信息(Downlink Control Information，DCI)，发送的ZP ULRS的配置信息。
具体来说，终端具体可以接收网络设备通过高层信令或DCI，所发送的ZP ULRS的配置信息。
例如，所述高层信令可以是无线物理资源控制(Radio Resource Control，RRC)消息，具体可以通过RRC消息中的信息元素(Information Element，IE)携带所述ZP ULRS的配置信息，所述RRC消息可以为现有技术中的RRC消息，例如，RRC连接重配置(RRC CONNECTION RECONFIGURATION)消息等，本实施例对此不进行限定，通过对已有的RRC消息的IE进行扩展携带所述ZP ULRS的配置信息，或者所述RRC消息也可以为不同于现有技术中已有的RRC消息。
再例如，所述高层信令可以是媒体访问控制(Media Access Control，MAC)控制元素(Control Element，CE)消息，具体还可以通过增加新的MAC CE消息携带所述ZP ULRS的配置信息。
可选地，在本实施例的一个可能的实现方式中，在101中，所接收的所述配置信息可以包括但不限于资源配置信息和激活信息，本实施例对此不进行特别限定。
在本实施例中，资源配置信息与激活信息，这两个信息，可以是独立的两个信息，或者还可以是一个信息，本实施例对此不进行特别限定。
例如，终端可以接收网络设备通过RRC消息，所发送的ZP ULRS的资源配置信息。
或者，再例如，终端可以接收网络设备通过DCI或者MAC CE消息，所发送的ZP ULRS的激活信息。
其中，所述资源配置信息，用于指示为所述ZP ULRS所配置的资源。
本实施例中，所述资源可以包括但不限于时域资源、频域资源以及序列资源中的至少一项，本实施例对此不进行特别限定。
例如，所述时域资源可以是ZP ULRS所在的时隙或者正交频分复用(Orthogonal Frequency Division Multiple，OFDM)符号。
或者，再例如，所述频域资源可以是ZP ULRS所占用的子载波或者物理资源块(Resource Block，RB)。
所述序列资源可以是所述ZP ULRS所使用的循环移位、正交掩码(Orthogonal Cover Code，OCC)或者序列标识(Identity，ID)。
本实施例中，所述为ZP ULRS所配置的资源可以重用为对应的NZP ULRS所配置的资源。
例如，网络设备可以配置NZP ULRS与ZP ULRS共用相同的N个资源(N为大于或等于1的整数)，进而通过激活信息指示ZP ULRS所占用其中的哪个资源。
其中，所述激活信息，用于指示是否激活所述ZP ULRS，即用于指示所述ZP ULRS是否生效。其中，所述的“激活”，还可以称为触发， 也可以称为使能，本实施例对此不进行特别限定。
具体来说，所述激活信息可以采用1比特信息表示，例如，1可以表示激活状态；0可以表示非激活状态。
在一个具体的实现过程中，在101中，具体可以接收所述网络设备发送的DCI，所述DCI中包含非周期的ZP SRS触发信令，用于触发ZP SRS。其中，所述非周期的ZP SRS触发信令，则可以作为激活信息。
在该实现方式中，当一个终端A被触发传输NZP SRS时，如果另一个终端B的上行传输与所述NZP SRS复用相同的资源，则终端B可以被非周期的ZP SRS触发信令，触发与所述NZP SRS对应的ZP SRS，从而在所述NZP SRS所占用的资源上不传输上行信号，能够避免对NZP SRS的干扰。
在另一个具体的实现过程中，在101中，具体可以接收所述网络设备发送的用于调度上行传输的DCI，所述DCI中包含所述激活信息，用于激活承载所述上行传输的物理资源区域中的ZP DMRS或ZP PTRS。
其中，所述上行传输，可以为上行数据传输，或者还可以为上行信道状态信息(Channel State Information，CSI)上报，本实施例对此不进行特别限定。
例如，终端和网络设备可以预先约定好，或者由网络设备配置ZP DMRS所使用的物理资源或DMRS端口，当终端接收到用于调度上行传输的DCI，需要在某个时隙进行所述上行传输时，则可以在所述时隙中激活所述ZP DMRS，即在所述时隙中的ZP DMRS或者ZP DMRS的DMRS端口所对应的物理资源上不传输上行数据、上行CSI或者DMRS。
这样，当一个终端和其他终端进行多用户多输入多输出(Multi-User Multiple-Input Multiple-Output，MU-MIMO)传输时，如果两个终端使用不同的DMRS端口，且不同端口占用不同的物理资源，则一个终端可以在复用终端传输DMRS的物理资源上不传输上行信号，以降低对复用终端的干扰。
或者，再例如，终端和网络设备可以预先约定好，或者由网络设备配置ZP PTRS所使用的物理资源或PTRS端口，当终端接收到用于调度上行传输的DCI，需要在某个时隙进行所述上行传输时，则可以在所述时隙中激活所述ZP PTRS，即在所述时隙中的ZP PTRS或者ZP PTRS的PTRS端口所对应的物理资源上不传输上行数据、上行CSI或者DMRS。
这样，当一个终端和其他终端进行MU-MIMO传输时，如果两个终端使用不同的PTRS端口，且不同端口占用不同的物理资源，则一个终端可以在复用终端传输PTRS的物理资源上不传输上行信号，以降低对复用终端的干扰。
进一步地，在该实现方式中，所述激活信息，还可以进一步用于指示所激活的上行参考信号为ZP ULRS，或者为NZP ULRS。
具体来说，所述激活信息可以采用2比特信息表示，例如，00可以表示非激活状态；01可以表示所激活的上行参考信号为NZP ULRS；10可以表示所激活的上行参考信号为ZP ULRS；11暂时不用。
例如，如果所激活的上行参考信号为NZP ULRS，则终端需要在对应的资源上传输所述NZP ULRS；如果所激活的上行参考信号为ZP ULRS，则终端不需要在对应的资源上传输上行参考信号，且需要预留 相应的资源。这样，无论一个终端是传输NZP ULRS，还是需要对其他终端传输NZP ULRS对应的资源进行资源预留，都可以采用相同的信令来进行指示，从而简化信令设计。
进一步地，在该实现方式中，所述激活信息，还可以进一步用于指示从所述资源配置信息所指示的为所述ZP ULRS所配置的多个资源中，选择所激活的所述零功率的上行参考信号所占用的资源。
具体来说，网络设备可以预先配置ZP ULRS所占用的多个资源。相应地，所述激活信息，具体可以从网络设备所配置的ZP ULRS所占用的多个资源中，选择ZP ULRS所占用的至少一个资源。例如，可以采用索引(index)或位图(bitmap)的方式指示。
进一步地，在该实现方式中，所述激活信息，还可以进一步用于指示所激活的所述零功率的上行参考信号所占用的天线端口。
例如，如果所激活的所述ZP ULRS为ZP DMRS或ZP PTRS，则所述激活信息可以用于指示所述ZP DMRS所占用的DMRS端口或者ZP PTRS所占用的PTRS端口，说明其他终端在相同资源上传输所占用的DMRS端口或PTRS端口。
可选地，在本实施例的一个可能的实现方式中，在102中，若所述ZP ULRS没有被激活，则所述ZP ULRS不需要占用资源，即ZP ULRS所占用的资源为空；若所述ZP ULRS被激活，则可以根据所述ZP ULRS的配置信息，确定所述ZP ULRS所占用的资源。
本发明中，所述ZP ULRS与所述NZP ULRS为相同类型的上行参考信号，或者为不同类型的上行参考信号，本实施例对此不进行特别限定。
例如，可以在ZP DMRS所占用的资源上不传输DMRS和/或PTRS。
或者，再例如，可以在ZP PTRS所占用的资源上不传输DMRS和/或SRS。
基于本发明所提供的上行信号的传输方法，可以在一些终端传输上行参考信号时，同时使得其他终端在相应资源上灵活进行资源空闲，从而避免其他终端传输的上行信号对这些上行参考信号的干扰，能够保证终端的上行参考信号的可靠传输，从而提高了这些上行参考信号的传输性能。
本实施例中，通过接收网络设备发送的零功率的上行参考信号的配置信息，进而根据所述配置信息，确定所述零功率的上行参考信号所占用的资源，使得能够在所述资源上，不发送上行数据，和/或，在所述资源上，不发送非零功率的上行参考信号，由于终端进行了资源预留，有效地避免了终端在所预留的资源上传输的上行信号对其他终端在所预留的资源上传输的上行参考信号所造成的干扰，能够保证终端的上行参考信号的可靠传输，从而提高了这些上行参考信号的传输性能。
图2为本发明另一实施例提供的另一种上行信号的传输方法的流程示意图，如图2所示。
201、根据零功率的上行参考信号(Zero-Power Uplink Reference Signal，ZP ULRS)所占用的资源，获得所述零功率的上行参考信号的配置信息。
202、向终端发送所述配置信息。
203、在所述资源上，不接收上行数据；和/或在所述资源上，不接收非零功率的上行参考信号(Non-Zero-Power Uplink Reference Signal， NZP ULRS)。
在203中，在所述资源上，不接收上行数据，具体可以为：在所述资源上，对上行数据进行速率匹配或打孔处理。
需要说明的是，201～203的执行主体可以为网络设备。
本实施例的主要思想就是，通过网络设备的配置和向终端指示，激活零功率的上行参考信号，可以在一些终端传输上行参考信号(即非零功率的上行参考信号)时，同时指示其他终端在相应的资源上进行资源空闲，从而避免其他终端所传输的上行参考信号的干扰，提高这些上行参考信号的传输性能。
这样，通过根据零功率的上行参考信号所占用的资源，获得所述零功率的上行参考信号的配置信息，进而向终端发送所述配置信息，使得能够在所述资源上，不接收上行数据，和/或在所述资源上，不接收非零功率的上行参考信号，由于终端进行了资源预留，有效地避免了终端在所预留的资源上传输的上行信号对其他终端在所预留的资源上传输的上行参考信号所造成的干扰，能够保证终端的上行参考信号的可靠传输，从而提高了这些上行参考信号的传输性能。
可选地，在本实施例的一个可能的实现方式中，所述ZP ULRS可以包括但不限于ZP SRS、ZP DMRS或ZP PTRS这些现有的ULRS，或者还可以为NR***新定义的其他ZP ULRS，本实施例对此不进行特别限定。
可选地，在本实施例的一个可能的实现方式中，所述NZP ULRS可以包括但不限于NZP SRS、NZP DMRS或NZP PTRS，或者还可以为NR***新定义的其他NZP ULRS，本实施例对此不进行特别限定。
可选地，在本实施例的一个可能的实现方式中，在202中，具体可以通过高层信令或下行控制信息(Downlink Control Information，DCI)，向终端发送ZP ULRS的配置信息。
例如，所述高层信令可以是无线物理资源控制(Radio Resource Control，RRC)消息，具体可以通过RRC消息中的信息元素(Information Element，IE)携带所述ZP ULRS的配置信息，所述RRC消息可以为现有技术中的RRC消息，例如，RRC连接重配置(RRC CONNECTION RECONFIGURATION)消息等，本实施例对此不进行限定，通过对已有的RRC消息的IE进行扩展携带所述ZP ULRS的配置信息，或者所述RRC消息也可以为不同于现有技术中已有的RRC消息。
再例如，所述高层信令可以是媒体访问控制(Media Access Control，MAC)控制元素(Control Element，CE)消息，具体还可以通过增加新的MAC CE消息携带所述ZP ULRS的配置信息。
可选地，在本实施例的一个可能的实现方式中，在201中，所获得的所述配置信息可以包括但不限于资源配置信息和激活信息，本实施例对此不进行特别限定。
在本实施例中，资源配置信息与激活信息，这两个信息，可以是独立的两个信息，或者还可以是一个信息，本实施例对此不进行特别限定。
例如，网络设备可以通过RRC消息，向终端发送ZP ULRS的资源配置信息。
或者，再例如，网络设备可以通过DCI或者MAC CE消息，向终端发送ZP ULRS的激活信息。
其中，所述资源配置信息，用于指示为所述ZP ULRS所配置的资 源。
本实施例中，所述资源可以包括但不限于时域资源、频域资源以及序列资源中的至少一项，本实施例对此不进行特别限定。
例如，所述时域资源可以是ZP ULRS所在的时隙或者正交频分复用(Orthogonal Frequency Division Multiple，OFDM)符号。
或者，再例如，所述频域资源可以是ZP ULRS所占用的子载波或者物理资源块(Resource Block，RB)。
所述序列资源可以是所述ZP ULRS所使用的循环移位、正交掩码(Orthogonal Cover Code，OCC)或者序列标识(Identity，ID)。
本实施例中，所述为ZP ULRS所配置的资源可以重用为对应的NZP ULRS所配置的资源。
例如，网络设备可以配置NZP ULRS与ZP ULRS共用相同的N个资源(N为大于或等于1的整数)，进而通过激活信息指示ZP ULRS所占用其中的哪个资源。
其中，所述激活信息，用于指示是否激活所述ZP ULRS。其中，所述的“激活”，还可以称为触发，也可以称为使能，本实施例对此不进行特别限定。
具体来说，所述激活信息可以采用1比特信息表示，例如，1可以表示激活状态；0可以表示非激活状态。
在一个具体的实现过程中，在202中，具体可以向所述终端发送DCI，所述DCI中包含非周期的ZP SRS触发信令，用于触发ZP SRS。其中，所述非周期的ZP SRS触发信令，则可以作为激活信息。
在该实现方式中，当一个终端A被触发传输NZP SRS时，如果另 一个终端B的上行传输与所述NZP SRS复用相同的资源，则终端B可以被非周期的ZP SRS触发信令，触发与所述NZP SRS对应的ZP SRS，从而在所述NZP SRS所占用的资源上不传输上行信号，能够避免对NZP SRS的干扰。
在另一个具体的实现过程中，在202中，具体可以向所述终端发送用于调度上行传输的DCI，所述DCI中包含所述激活信息，用于激活承载所述上行传输的物理资源区域中的ZP DMRS或ZP PTRS。
其中，所述上行传输，可以为上行数据传输，或者还可以为上行信道状态信息(Channel State Information，CSI)上报，本实施例对此不进行特别限定。
例如，终端和网络设备可以预先约定好，或者由网络设备配置ZP DMRS所使用的物理资源或DMRS端口，当终端接收到用于调度上行传输的DCI，需要在某个时隙进行所述上行传输时，则可以在所述时隙中激活所述ZP DMRS，即在所述时隙中的ZP DMRS或者ZP DMRS的DMRS端口所对应的物理资源上不传输上行数据、上行CSI或者DMRS。
这样，当一个终端和其他终端进行多用户多输入多输出(Multi-User Multiple-Input Multiple-Output，MU-MIMO)传输时，如果两个终端使用不同的DMRS端口，且不同端口占用不同的物理资源，则一个终端可以在复用终端传输DMRS的物理资源上不传输上行信号，以降低对复用终端的干扰。
或者，再例如，终端和网络设备可以预先约定好，或者由网络设备配置ZP PTRS所使用的物理资源或PTRS端口，当终端接收到用于调度上行传输的DCI，需要在某个时隙进行所述上行传输时，则可以在所 述时隙中激活所述ZP PTRS，即在所述时隙中的ZP PTRS或者ZP PTRS的PTRS端口所对应的物理资源上不传输上行数据、上行CSI或者DMRS。
这样，当一个终端和其他终端进行MU-MIMO传输时，如果两个终端使用不同的PTRS端口，且不同端口占用不同的物理资源，则一个终端可以在复用终端传输PTRS的物理资源上不传输上行信号，以降低对复用终端的干扰。
进一步地，在该实现方式中，所述激活信息，还可以进一步用于指示所激活的上行参考信号为ZP ULRS，或者为NZP ULRS。
具体来说，所述激活信息可以采用2比特信息表示，例如，00可以表示非激活状态；01可以表示所激活的上行参考信号为NZP ULRS；10可以表示所激活的上行参考信号为ZP ULRS；11暂时不用。
例如，如果所激活的上行参考信号为NZP ULRS，则终端需要在对应的资源上传输所述NZP ULRS；如果所激活的上行参考信号为ZP ULRS，则终端不需要在对应的资源上传输上行参考信号，且需要预留相应的资源。这样，无论一个终端是传输NZP ULRS，还是需要对其他终端传输NZP ULRS对应的资源进行资源预留，都可以采用相同的信令来进行指示，从而简化信令设计。
进一步地，在该实现方式中，所述激活信息，还可以进一步用于指示从所述资源配置信息所指示的为所述ZP ULRS所配置的多个资源中，选择所激活的所述零功率的上行参考信号所占用的资源。
具体来说，网络设备可以预先配置ZP ULRS所占用的多个资源。相应地，所述激活信息，具体可以从网络设备所配置的ZP ULRS所占 用的多个资源中，选择ZP ULRS所占用的至少一个资源。例如，可以采用索引(index)或位图(bitmap)的方式指示。
进一步地，在该实现方式中，所述激活信息，还可以进一步用于指示所激活的所述零功率的上行参考信号所占用的天线端口。
例如，如果所激活的所述ZP ULRS为ZP DMRS或ZP PTRS，则所述激活信息可以用于指示所述ZP DMRS所占用的DMRS端口或者ZP PTRS所占用的PTRS端口，说明其他终端在相同资源上传输所占用的DMRS端口或PTRS端口。
可选地，在本实施例的一个可能的实现方式中，若所述ZP ULRS没有被激活，则所述ZP ULRS不需要占用资源，即ZP ULRS所占用的资源为空；若所述ZP ULRS被激活，则可以根据所述ZP ULRS的配置信息，确定所述ZP ULRS所占用的资源。
本发明中，所述ZP ULRS与所述NZP ULRS为相同类型的上行参考信号，或者为不同类型的上行参考信号，本实施例对此不进行特别限定。
例如，可以在ZP DMRS所占用的资源上不传输DMRS和/或PTRS。
或者，再例如，可以在ZP PTRS所占用的资源上不传输DMRS和/或SRS。
基于本发明所提供的上行信号的传输方法，可以在一些终端传输上行参考信号时，同时使得其他终端在相应资源上灵活进行资源空闲，从而避免其他终端传输的上行信号对这些上行参考信号的干扰，能够保证终端的上行参考信号的可靠传输，从而提高了这些上行参考信号的传输性能。
本实施例中，通过根据零功率的上行参考信号所占用的资源，获得所述零功率的上行参考信号的配置信息，进而向终端发送所述配置信息，使得能够在所述资源上，不接收上行数据，和/或在所述资源上，不接收非零功率的上行参考信号，由于终端进行了资源预留，有效地避免了终端在所预留的资源上传输的上行信号对其他终端在所预留的资源上传输的上行参考信号所造成的干扰，能够保证终端的上行参考信号的可靠传输，从而提高了这些上行参考信号的传输性能。
