Description

一种发送上行信号的方法及装置 技术领域
本申请涉及无线通信技术领域，特别涉及一种发送上行信号的方法及装置。
背景技术
随着通信技术的不断发展，终端设备可以同时接入两个网络设备，这种接入方式称为双连接(dual connectivity，DC)。例如，终端设备同时接入第一网络设备和第二网络设备时，可能会同时向第一网络设备和第二网络设备发送上行信号，容易导致上行信号间的交叉调制，另外，终端设备当同时向第一网络设备和第二网络设备发送上行信号时，还可能导致所需的发射功率超出终端设备所支持的最大发射功率。
在一种典型的应用场景中，终端设备同时接入长期演进(long term evolution，LTE)通信系统中的第一网络设备和新空口(new radio interface，NR)通信系统中的第二网络设备，其中，LTE通信系统工作在频分双工(frequency division duplex，FDD)模式，NR通信系统工作在时分双工(time division duplex，TDD)模式。对于第一网络设备来说，由于LTE通信系统工作在FDD模式，因此，第一网络设备可以与终端设备同时进行上、下通信。因而终端设备与第一网络设备之间的上行通信、以及与第二网络设备之间的上、下行通信可能同时发生。当终端设备与第一网络设备之间的上行通信、以及与第二网络设备之间的上、下行通信可能同时发生时，终端设备同时向第一网络设备和第二网络设备发送上行信号导致的上行信号间的交叉调制，可能会对终端设备与第一网络设备之间的下行通信造成干扰，影响终端设备接收第一网络设备发送的下行信号。
现有技术中，为了避免终端设备接入LTE通信系统中的第一网络设备和NR通信系统中的第二网络设备时，同时向第一网设备和第二网络设备发送上行信号，由第一网络设备向终端设备发送参考上下行配置信息。终端设备可以根据第一网络设备发送的参考配置信息，确定用于向第一网络设备发送上行信号的子帧。其中，用于向第一网络设备发送上行信号的子帧可以简称为上行子帧。终端设备可以在确定的上行子帧上向第一网络设备发送上行信号。其中，参考上下行配置可以如表1所示。例如，第一网络设备发送给终端设备的参考配置信息为参考上下行配置0，则终端设备确定子帧2、3、4、7、8、9为上行子帧，可以在这些子帧上向第一网络设备发送上行信号，而不再这些子帧对应时间段向第二网络设备发送上行信号。此外，第一网络设备还可以通过为终端设备配置一个偏移值，调整上行子帧的编号。例如第一网络设备发送给终端设备的参考上下行配置信息为参考上下行配置1，当配置的偏移值为0，则终端设备确定子帧2、3、7、8为上行子帧，当配置的偏移值为2时，则终端设备确定子帧4、5、9和0为上行子帧。
表1
Figure PCTCN2019071475-appb-000001
Figure PCTCN2019071475-appb-000002
虽然这种方式可以使得终端设备能够不同时向第一网络设备和第二网络设备同时发送上行信号，但是，无论第一网络设备给终端配置表1中的哪种参考上下行配置，在一个无线帧中至少有4个子帧不能被终端设备用来与第一网络设备进行上行通信。因此这种实现方式灵活度较差，此外，在这些不能够被终端设备用来与第一网络设备进行上行通信的子帧上，终端设备也可能在这些子帧对应的时间段内不与第二网络设备进行上行通信，从而导致资源的浪费，降低了资源利用率。
发明内容
本申请提供了一种发送上行信号的方法及装置，终端设备同时接入第一网络设备和第二网设备时，在不同时向第一网络设备和第二网络设备发送上行信号的情况下，有助于提高终端设备向第一网络设备发送上行信号的灵活性，以及提高资源的利用率。

本申请实施例涉及的网络设备为接入网设备，可以是基站，或者接入点，或者可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备等。当网络设备为基站时，基站可用于将收到的空中帧与网际协议(Internet Protocol，IP)分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括IP网络。基站还可用于协调对空中接口的属性管理。例如，基站可以是宽带码分多址(wideband code division multiple access，WCDMA)中的节点B(Node B)，还可以是LTE通信系统中的演进型基站(evolutional Node B，eNB)，也可以是NR通信系统中的基站，或者是下一代移动通信基站(next generation Node B，gNB)等，本申请实施例并不限定。
具体的，本申请实施例的终端设备可以同时接入两个网络设备，这种接入方式称之为DC。示例的，终端设备同时接入第一网络设备和第二网络设备。其中，第一网络设备与第二网络设备可以为同一通信系统中的两个网络设备，例如，第一网络设备和第二网络设备可以为LTE通信系统中的两个网络设备。第一网络设备和第二网络设备还可以为不同通信系统中的网络设备。例如，第一网络设备为LTE通信系统中的网络设备，第二网络设备为NR通信系统中的网络设备。需要说明的是，当第一网络设备和第二网络设备为不同通信系统中的网络设备、且不同通信系统采用的无线接入技术(radio access technology，RAT)不同时，终端设备同时接入第一网络设备和第二网络设备的这种连接方式又可以称之为多无线接入技术连接(multi-RAT dual connectivity，MR-DC)。
示例的，终端设备同时接入第一网络设备和第二网络设备，其中，第一网络设备为LTE通信系统中的接入网设备，可以简称为LTE接入网设备，第二网络设备为NR通信系统中的接入网设备，可以简称为NR接入网设备。由于LTE又被称为演进的通用陆面无线接入(evolved universal terrestrial radio access，E-UTRA)，当LTE接入网设备为主网络设备，NR接入网设备为辅网络设备时，终端设备的接入方式又可称之为演进的通用陆面无线接入与新空口双连接(E-UTRA NR dual connectivity，EN-DC)。随着通信系统的不断演进，终端设备当同时接入LTE接入网设备和NR接入网设备，若NR接入网设备为主网络设备，LTE接入网设备为辅网络设备，则终端设备的这种接入方式可称之为新空口与演进的通用陆面无线接入双连接(NR E-UTRA dual connectivity，NE-DC)。
本申请实施例中的第一网络设备和第二网络设备可以部署在同一站点上，也可以部署在不同的站点上。示例的，第一网络设备和第二网络设备部署在同一站点上时，本申请实 施例的通信系统架构的示意图如图1所示，包括网络设备和终端设备，其中网络设备包括第一网络设备和第二网络设备。具体的，当第一网络设备与第二网络设备部署在同一站点上时，可以共享相同的硬件设备(例如收发器)，也可以不共享相同硬件设备。例如，如图2a所示，为第一网络设备和第二网络设备部署在同一站点上，且共享收发器时，通信系统的架构示意图。如图2a所示，第一网络设备包括第一处理器211和收发器213，第二网络设备包括第二处理器212和收发器213，第一网络设备和第二网络设备共享收发器213。再例如，如图2b所示，第一网络设备和第二网络设备部署在同一站点上，且但不共享收发器时，通信系统的架构示意图。如图2b所示，第一网络设备包括第一处理器221和第一收发器222，第二网络设备包括第二处理器231和第二收发器232。
示例的，第一网络设备和第二网络设备部署在不同的站点上时，本申请实施例的通信系统的架构示意图如图3所示，包括第一网络设备、第二网络设备和终端设备。应理解，当第一网络设备和第二网络设备部署在不同的站点上时，为独立的设备，分别具有独立的收发器和处理器，示例的，如图4所示，第一网络设备包括第一处理器401和第一收发器402，第二网络设备包括第二处理器411和第二收发器412。
本申请实施例中，由于终端设备当同时接入第一网络设备和第二网络设备时，可以同时向第一网络设备和第二网络设备发送上行信号，容易导致终端所需求的功率超出终端设备所支持的最大功率。另外，终端设备当同时向第一网络设备和第二网络设备发送上行信号时，还容易导致上行信号间的交叉调制。需要说明的是，终端设备向第一网络设备发送上行信号可以称之为终端设备与第一网络设备之间的上行通信，终端设备向第二网络设备发送上行信号可以称之为终端设备与第二网络设备之间的上行通信。此外，终端设备接收第一网络设备发送的下行信号可以称之为终端设备与第一网络设备之间的下行通信，终端设备接收第二网络设备发送的下行信号可以称之为终端设备与第二网络设备之间的下行通信。
在一些实施例中，当第一网络设备工作在FDD模式时，第一网络设备为终端设备配置两个成对频段，其中一个频段用于上行通信，另一个频段用于下行通信，因而，允许终端设备可以与第一网络设备之间的上行通信和下行通信可以同时进行。例如，第一网络设备工作在FDD模式时，为终端设备分配1.8GHz附近的两个成对的频段，如1.85GHz的频段和1.75GHz的频段，其中1.85GHz的频段用于终端设备与第一网络设备进行上行通信，1.75GHz的频段用于终端设备与第一网络设备进行下行通信。
当第一网络设备工作在FDD模式时，终端设备与第一网络设备之间的上行通信、下行通信、以及终端设备与第二网络设备之间的上行通信可能会同时发生，而终端设备与第一网络设备和第二网络设备同时的上行通信导致的上行信号间的交叉调制，会干扰对终端设备与第一网络设备之间的下行通信，影响终端设备接收来自第一网络设备发送的下行信号。其中，当第一网络设备工作在FDD模式时，第二网络设备可以工作在TDD模式，也可以工作在FDD模式。示例的，当第二网络设备工作在TDD模式时，第二网络设备为终端设备配置一个非成对的频段，既用于终端设备与第二网络设备之间进行上行通信，又用于终端设备与第二网络设备之间进行下行通信，但是，终端设备与第二网络设备之间的上、下行通信不是同时进行的。例如，第二网络设备工作在TDD模式时，第二网络设备为终端设备配置的一个非成对的频段，例如3.5GHz附近的频段，终端设备与第二网络设备在不同的时间段分别在3.5GHz附近的频段上进行上行通信和下行通信。
有鉴于此，本申请实施例提供了一种发送上行信号的方法，有助于使得终端设备当同时接入第一网络设备和第二网络设备时，能够不同时向第一网络设备和第二网络设备发送上行信号，从而有助于提高终端设备向第一网络设备和第二网络设备发送上行信号的可靠性。
需要说明的是，本申请实施例不限定第一网络设备工作在FDD模式，还是TDD模式，也不限定第二网络设备工作在FDD模式，还是TDD模式。
示例的，如图5所示，为本申请实施例发送上行信号的方法的流程示意图。具体包括以下步骤。
步骤501，第一网络设备向终端设备发送第一指示信息，第一指示信息用于指示第一时间段，第一时间段为第一网络设备为终端设备配置的上行时间段。
应理解，本申请实施例中的上行时间段用于进行上行通信。因此，第一时间段用于终端设备与第一网络设备进行上行通信。具体的，本申请实施例中的第一时间段可以为一个或多个时间单元，其中时间单元可以为帧、子帧、时隙(slot)、迷你时隙(mini-slot)等。通常情况下，对于LTE来说，第一时间段可以为一个或多个子帧。
例如，如图6a所示，第一网络设备为终端设备配置的上行子帧为子帧2、3、4、7、8、9，则第一时间段包括子帧2、3、4、7、8、9。再例如，如图6b所示，第一网络设备为终端设备配置的上行子帧为子帧2、3和7，则第一时间段包括子帧2、3和7。又示例如，如图6c所示，第一网络设备为终端设备配置的上行子帧为子帧2和3，则第一时间段包括子帧2和3。
在一些实施例中，第一指示信息可以为参考上下行配置信息，也可以包括参考上下行配置信息和偏移值。示例的，参考上下行配置信息可以为表1中所示的参考上下行配置索引。例如，第一网络设备向终端设备发送表1中的参考上下行配置0，则为终端设备配置的上行子帧为子帧2、3、4、7、8和9。再例如，第一网络设备向终端设备发送表1中的参考上下行配置2，则为终端设备配置的上行子帧为子帧2、3和7。又例如，第一网络设备向终端设备发送表1中的参考上下行配置4，则为终端设备配置的上行子帧为子帧2和3。还例如，第一网络设备向终端设备发送参考上下行配置1和偏移值2，则为终端设备配置的上行子帧为子帧4、5、9和0。需要说明的是，本申请实施例中偏移值的取值范围可以根据实际情况进行相应的配置。例如，偏移值的取值范围可以为大于或等于0且小于或等于9的自然数。此外，本申请实施例的第一指示信息还可以通过其它方式实现，例如时间信息等，对此不作限定。
应理解，本申请实施例中，终端设备在第一时间段上不向第二网络设备发送上行信号。以图6a为例，第一时间段包括子帧2、3、4、7、8和9，则终端设备在子帧2、3、4、7、8和9上不向第二网络设备发送上行信号。特别的，第二网络设备与终端设备之间用于通信的时间单元如果不是子帧，例如时隙、迷你时隙等，则终端设备在与子帧2、3、4、7、8、9在时间上重叠的时间单元上不向第二网络设备发送上行信号。例如，第二网络设备与终端设备之间用于通信的时间单元为时隙，如图7所示，对于终端设备来说，用于与第二网络设备进行通信的时隙4、5、6、7、8、9、14、15、16、17、18和19在时间上与子帧2、3、4、7、8、9重叠，则终端设备在时隙4、5、6、7、8、9、14、15、16、17、18和19上不向第二网络设备进行上行通信。示例的，若时隙4、5、6、7、8、9、14、15、16、17、18和19中存在第二网络设备为终端设备配置的上行时隙，终端设备也不在该上行时 隙上与第二网络设备进行上行通信，即接收第二网络设备发送的上行信号。但是，终端设备可以在时隙4、5、6、7、8、9、14、15、16、17、18和19上与第二网络设备进行下行通信。又例如，如图8所示，对于终端设备来说，用于与第二网络设备进行通信的时隙5、6、7、8、9、15、16、17、18、19、时隙4的部分、时隙10的部分和时隙14的部分在时间上与子帧2、3、4、7、8、9重叠，则在一些实例中，终端设备可以在时隙4、5、6、7、8、9、10、14、15、16、17、18和19上均不向第二网络设备发送上行信号，有助于避免终端设备同时向第一网络设备和第二网络设备发送上行信号。但是，终端设备可以在时隙4、5、6、7、8、9、10、14、15、16、17、18和19上与第二网络设备进行下行通信。
需要说明的是，终端设备当在第一时段向第一网络设备发送上行信号、以及在第一时间段接收第二网络设备发送的下行信号时，向第一网络设备发送上行信号所使用的载波或频段和第二网络设备接收发送的下行信号所使用的载波或频段是不同的。
在一些实施例中，终端设备可以在第一时间段上向第一网络设备发送上行信号，具体的，由于第一时间段为第一网络设备配置给终端设备的上行时间段，通常情况下是固定的，因此，终端设备在第一时间段上向第一网络设备发送的上行信号可以为在物理上行控制信道(physical layer uplink control channel，PUCCH)上传输的信号。此外，在另一些实施例中，终端设备还可以在第一时间段上向第一网络设备发送其它信号，例如，在物理上行共享信道(physical layer uplink shared channel，PUSCH)上传输的信号、在物理随机接入信道(physical layer random access channel，PRACH)上传输的信号，或者探测参考信号(sounding reference signal，SRS)等。
步骤502，终端设备接收到第一指示信息后，确定第二时间段，第二时间段为第二网络设备为终端设备配置的下行时间段、且与第一时间段不重叠。
需要说明的是，通常情况下，本申请实施例中第二时间段和第一时间段之间不重叠指的是第二时间段和第一时间段时间上没有重合。
示例的，如图9所示，时刻t1与时刻t2之间的时间段为T1，时刻t2与时刻t4之间的时间段为T2，时刻t2与时刻t3之间的时间段为T3，时刻t1与时刻t3之间的时间段为T4，时刻t3和时刻t4之间的时间段为T5。其中，T1与T2不重叠，T1和T5不重叠，T3和T5不重叠，T4和T3存在部分重叠，重叠的部分为T3，T4和T2存在部分重叠，重叠的部分为T3，此外，T2与由T3和T5组成的时间段完全重叠。例如T2为第一时间段，T4为第二网络设备为终端设备配置的下行时间段，则T2与T4之间在时间上重叠的时间段为T3，而T2与T4之间在时间上不重叠的时间段为T1，因此第二时间段为T1。
在一些实施例中，第二网络设备可以通过向终端设备发送第二指示信息，来指示为终端设备配置的下行时间段。其中，下行时间段用于下行通信，即终端设备可以用于在下行时间段接收第二网络设备发送的下行信号。在一些实施例中，终端设备与第二网络设备之间是以时间单元为单位进行通信的。时间单元可以为帧、子帧、时隙(slot)、迷你时隙(mini-slot)等。其中，第二网络设备为终端设备配置的下行时间段可以包括一个或多个时间单元。需要说明的是，本申请实施例中终端设备与第一网络设备用于通信的时间单元、与终端设备与第二网络设备之间通信的时间单元可以是相同的，也可以是不同的。例如，通常情况下，对于NR来说，终端设备与第二网络设备之间通信的时间单元为时隙。应理解，在NR中，不同的子载波间隔，对应的时隙不同。例如，终端设备与第二网络设备之间采用30KHz的子载波间隔时，每个时隙的时长为0.5ms。再例如，终端设备与第二网络 设备之间采用60KHz的子载波间隔时，每个时隙的时长为0.25ms。除此之外，子载波间隔还可以为15KHz、120KHz等。
以图7为例，第二网络设备为终端设备配置的下行时隙为时隙2、3、4、5、6、7、8、9、10和11，而第一网络设备为终端设备配置的上行子帧为子帧2、3、4、7、8和9，而时隙4、5、6、7、8和9在时间上与子帧2、3和4重叠，时隙2、3、10和11与子帧2、3、4、7、8和9在时间上没有重叠，因此，终端设备与第一网络设备来通信时，第二时间段包括子帧1和子帧5，终端设备与第二网络设备通信时，第二时间段包括时隙2、3、10和11。
在一些实施例中，第二指示信息可以为上下行配置信息，例如，对于工作在TDD模式的NR接入网设备来说，第二指示信息可以为上下行时隙配置信息，终端设备可以根据上下行时隙配置信息确定NR接入网设备为终端设备配置的上行时隙、下行时隙和/或灵活时隙。可以理解的是，终端设备可以在灵活时隙上与第二网络设备进行上行通信或者下行通信。
在另一些实施例中，第二网络设备还可以只为终端设备配置下行时间段，终端设备在接收到第二指示信息后，可以确定哪些是下行时间段，除了下行时间段以外的其他时间段可以用于上行通信，也可以用于下行通信等。本申请实施例对第二网络设备为终端设备配置下行时间段的方式不作限定。
应理解，本申请实施例中第二网络设备为终端设备配置的下行时间段包括第二时间段，即第二时间段能够用于终端设备接收来自第二网络设备的下行信号。
步骤503，终端设备在第二时间段向第一网络设备发送第一上行信号。
第一上行信号可以为在PUSCH、或者PRACH上传输的信号，也可以为在PUCCH上传输的信号等。然而，由于第二时间段是不固定的，是随着可以随着第一时间段或者第二网络设备为终端设备配置的下行时间段的变化而变化，如果终端设备在第二时间段上向第一网络设备发送在PUCCH上传输的信号，在具体实现起来较为复杂，因此，为了简化方案的实现方式，在一些实施例中，第一上行信号不包括在PUCCH上传输的信号。
需要说明的是，在第二时间段内，终端设备能够向第一网络设备发送上行信号，同时也可以接收来自第二网络设备的下行信号，在一些实现方式中，终端设备会在第一载波上向第一网络设备发送上行信号，而在第二载波上从第二网络设备接收下行信号，第一载波和第二载波为不同的载波，也就是说第一载波和第二载波在频域上占用不同的频率资源。
本申请实施例中，由于第一时间段是第一网络设备指示的，而第二时间段是根据第二网络设备配置的下行时间段灵活确定的，从而有助于提高资源的利用率，而且使得终端设备向第一网络设备发送上行信号更加灵活。
此外，还需要说明的是，终端设备无论是在第一时间段上向第一网络设备发送上行信号，还是在第二时间段上向第一网络设备发送上行信号，所使用的载波或频段是相同的。但是，终端设备当在第一时间段上向第一网络设备发送上行信号后，接收到第一网络设备发送的指示信息，指示终端设备进行载波切换，则有可能使得终端设备在第一时间段和第二时间段上发送上行信号时所使用的载波不同。
进一步的，由于第二网络设备还可能为终端设备配置上行时间段和/或灵活时间段，终端设备在上行时间段或者灵活时间段可能向第二网络设备发送上行信号，也可能不向第二网络设备发送上行信号，例如终端设备可能在灵活时间段向第二网络设备发送下行信号， 因此，在本申请的一些实施例中，终端设备还可以确定第三时间段，其中，第三时间段包括第二网络设备为终端设备配置的上行时间段和/或灵活时间段、且与第一时间段不重叠。终端设备可以在第三时间段不向第二网络设备发送上行信号时，可以用于向第一网络设备发送第三上行信号。需要说明的是，终端设备当在第三时间段向第二网络设备发送上行信号时，则不在第三时间段上向第一网络设备发送第三上行信号。
应理解，终端设备当在第三时间段上需要向第二网络设备发送上行信号，也需要在第三时间段上向第一网络设备发送第三上行信号时，终端设备优先保证向第二网络设备发送上行信号，丢弃向第一网络设备发送的第三上行信号，以实现终端设备不同时向第一网络设备和第二网络设备发送上行信号。因此，在一些实施例中，终端设备在第三时间段上向第一网络设备发送的第三上行信号为在PUSCH上传输的信号，从而有助于避免终端设备丢弃重要信息。但是在具体实现时，终端设备也可以在第三时间段上向第一网络设备发送在PUCCH或者PRACH上传输的信号，也可以在第三时间段上向第一网络设备发送SRS等。
另外，可以理解的是，上行时间段用于上行通信，灵活时间段可以用于上行通信，也可以用于下行通信。其中，第二网络设备为终端设备配置的上行时间段可以包括一个或多个时间单元。具体的，时间单元可以为帧、子帧、时隙、迷你时隙等。例如，对于LTE来说，时间单元可以为子帧。再例如，对于NR来说，时间单元可以为时隙。还需说明的是，第二网络设备可以只为终端设备配置上行时间段，而不配置灵活时间段，也可以只为终端设备只配置灵活时间段，而不配置上行时间段，还可以既为终端设备配置上行时间段，又配置灵活时间段。
以图7为例，第一网络设备为终端设备配置的上行子帧为子帧2、3、4、7、8和9，第二网络设备为终端设备配置的上行时隙为时隙0、1、2、3、4、5，灵活时隙为12、13、14和15，时隙4、5、14、15与子帧2和子帧7在时间上重叠，因此，对于终端设备与第一网络设备通信来说，第三时间段包括子帧1和子帧6。对于终端设备与第二网络设备通信来说，第三时间段包括时隙0、1、2、3、12和13。
以图8为例，第一网络设备为终端设备配置上行子帧为子帧2、3、4、7、8和9，第二网络设备为终端设备配置的上行时隙为时隙0、1、2、3、4、5，灵活时隙为12、13、14和15，时隙4的部分、时隙5、时隙14的部分、时隙15与子帧2和子帧7在时间上重叠，虽然时隙4的部分以及时隙14的部分与子帧2和子帧7在时间上重叠，但是终端设备与第二网络设备之间是以时隙为单位进行通信的，因此，终端设备在时隙4和时隙14上不能向第二网络设备发送上行信号，对于终端设备与第一网络设备通信来说，第三时间段包括子帧1和子帧6。对于终端设备与第二网络设备通信来说，第三时间段包括时隙2的部分、时隙3、时隙4的部分、时隙12的部分、时隙13和时隙14的部分。
基于本申请实施例图5所示的发送上行信号的方法，本申请实施例终端设备接入第一网络设备和第二网络设备时的上行通信的方法，如图10所示，具体包括以下步骤。
步骤1001，第一网络设备向终端设备发送第一指示信息，第一指示信息用于指示第一时间段，第一时间段为第一网络设备为终端设备配置的上行时间段。
步骤1002，终端设备在接收到第一指示信息后，确定用于向第一网络设备发送第一上行信号的第二时间段，其中，第二时间段为第二网络设备为终端设备配置的下行时间段、 且第二时间段与第一时间段不重叠。
需要说明的是，本申请实施例中，终端设备可以在第二时间段有第一上行信号发送的需求时，可以在第二时间段上发送第一上行信号，可以在第二时间段上没有第一上行信号发送的需求时，不再第二时间段上发送第一上行信号。但是，终端设备无论是否在第二时间段上向第一网络设备发送第一上行信号，均可以在第二时间段上向第二网络设备发送下行信号。可以理解的是，终端设备用于承载在第二时间段上向第一网络设备发送的第一上行信号的载波或频段，与终端设备用于承载在第二时间段上接收第二网络设备发送的下行信号的载波或频段是不同的。
在一些实施例中，第一上行信号可以仅为在PUSCH上传输的信号。即终端设备在第二时间段上向第一网络设备仅发送在PUSCH上传输的信号。在另一些实施例中，第一上行信号为可以仅为在PUSCH和/或PRACH上传输的信号。即终端设备在第二时间段上向第一网络设备仅发送在PUSCH和/或PRACH上传输的信号。在其它一些实施例中，第一上行信号还可以包括在PUCCH、PRACH、或PUSCH等信道上传输的信号、或者SRS等。
此外，本申请实施例终端设备在第一时间段上不向第二网络设备发送上行信号，可以在第一时间段上向第二网络设备发送第二上行信号。
在一些实施例中，第二上行信号可以包括在PUCCH、PUSCH、PRACH等至少一个信道上传输的信号，第二上行信号还可以包括SRS等信号。
可以理解的是，本申请实施例中，第一时间段、第二时间段、第一指示信息、第二网络设备为终端设备配置下行时间段等的相关介绍可以参见图5所示的发送上行信号的方法中的相关介绍，在此不再赘述。
进一步的，本申请实施例终端设备还可以确定用于向第一网络设备发送第三上行信号的第三时间段，其中第三时间段包括第二网络设备为终端设备配置的上行时间段和/或灵活时间段，且与第一时间段不重叠。终端设备当在第三时间段上不向第二网络设备发送上行信号时，可以在第三时间段上向第一网络设备发送第三上行信号。示例的，第三上行信号可以仅为在PUSCH上传输的信号，即终端设备仅在第三时间段上向第一网络设备发送在PUSCH上传输的信号。
需要说明的是，本申请实施例中终端设备当在第三时间段上向第二网络设备发送上行信号时，不再第三时间段上向第一网络设备发送第三上行信号。此外，终端设备当在第三时间段上同时有向第一网络设备发送第三上行信号的需求，以及向第二网络设备发送上行信号的需求，则终端设备丢弃在第三时间段上需要向第一网络设备发送的第三上行信号，在第三时间段上向第二网络设备发送上行信号。有助于避免终端设备同时向第一网络设备和第二网络设备发送上行信号。
应理解，本申请实施例中第三时间段、第二网络设备为终端设备配置的上行时间段和/或灵活时间段等信息的具体实现方式，可以参见图5所示的发送上行信号的方法中的相关介绍，在此不再赘述。
以终端设备同时接入LTE接入网设备和NR接入网设备为例，结合具体的应用场景，对本申请实施例进行介绍。示例的，LTE接入网设备为LTE通信系统中的基站，如eNB，NR接入网设备为NR通信系统中的基站，例如gNB。一个典型LTE通信系统的部署方式为LTE通信系统工作在FDD模式，当终端设备接入LTE接入网设备后，LTE接入网设备 可以为终端设备配置两个成对的频段，例如1.8GHz附近的两个频段，例如第一频段和第二频段，其中第一频段用于上行通信，第二频段用于下行通信。一种典型的NR通信系统的部署方式为：NR通信系统工作在TDD模式，当终端设备接入NR接入网设备后，NR接入网设备可以为终端设备配置一个非成对的频段，例如第三频段，其中第三频段为3.5GHz附近的频段，终端设备可以在不同时刻通过第三频段实现上行通信和下行通信。
如图11所示，为结合上述应用场景，本申请实施例终端设备接入LTE接入网设备和NR接入网设备时的上行通信的方法流程示意图。具体包括以下步骤。
如图11所示，为本申请实施例终端设备接入LTE接入网设备和NR接入网设备时的上行通信的方法流程示意图。具体包括以下步骤。
步骤1101，LTE接入网设备在第二频段上向终端设备发送第一指示信息，第一指示信息用于指示第一上行子帧，第一上行子帧为LTE接入网设备为终端设备配置的上行子帧。
步骤1102，NR接入网设备在第三频段上向终端设备发送第二指示信息，第二指示信息用于指示上下行时隙配置。
步骤1103，终端设备在第二频段上接收到第一指示信息，以及在第三频段上接收到第二指示信息后，确定用于在第一频段上向LTE接入网设备发送第一上行信号的第二上行子帧，第二上行子帧与第一上行子帧不同，且第二上行子帧包括在时间上与NR接入网设备为终端设备配置的下行时隙重叠的部分。
其中，终端设备可以在第一上行子帧和第一频段上向LTE接入网设备发送上行信号，例如在PUCCH上传输的信号，还可以为在PUSCH、PRACH等信道上传输的信号，还可以为SRS等。但是，通常情况下，终端设备在与第一上行子帧在时间上重叠的时隙上不发送上行信号，以避免终端设备同时向LTE接入网设备和NR接入网设备发送上行信号。
终端设备当有在第二上行子帧发送第一上行信号的需求时，可以在第二上行子帧和第一频段上向LTE接入网设备发送第一上行信号。终端设备当没有在第二上行子帧上发送第一上行信号的需求时，可以不再第二上行子帧上发送第一上行信号。
其中，在一些实施例中，第一上行信号仅为在PUSCH上传输的信号，即终端设备在第二上行子帧和第一频段上只能向LTE接入网设备发送在PUSCH上传输的信号，而不能发送其它上行信号。在另一些实施例中，第一上行信号仅包括在PUSCH和PRACH上传输的信号，即终端设备在第二上行子帧和第一频段上只能向LTE接入网设备发送在PUSCH和/或PRACH上传输的信号，而不能发送其它上行信号。在其它一些实施例中，第一上行信号还可以包括在PUCCH、PRACH、或PUSCH等信道上传输的信号、或者SRS等。
此外，终端设备无论是否向LTE接入网设备发送第一上行信号，还可以在与第二上行子帧在时间上重叠的时隙和第三频段上接收NR接入网设备发送的下行信号。
在一些实施例中，终端设备还可以根据第一指示信息和第二指示信息，确定除第一上行子帧以外的子帧中、与NR接入网设备配置的上行时隙和/或灵活时隙在时间上重叠的子帧。本申请实施例为简化描述方式，将除第一上行子帧以外的子帧中、与NR接入网设备配置的上行时隙和/或灵活时隙在时间上重叠的子帧称之为第三上行子帧。
需要说明的是，终端设备当同时在与第三上行子帧在时间上重叠的时隙需要向NR接入网设备发送上行信号、以及在第三上行子帧需要向LTE接入网设备发送上行信号时，则丢弃需要向LTE接入网设备发送的上行信号，在与第三上行子帧在时间上重叠的时隙和第三频段上向NR接入网设备发送上行信号。终端设备当在与第三上行子帧在时间上重叠的 时隙不需要向NR接入网设备发送上行信号时，可以在终端设备有需求在第三上行子帧向LTE接入网设备发送上行信号时，在第三上行子帧和第一频段上向LTE接入网设备发送上行信号。在一些实施例中，终端设备在第三上行子帧向LTE接入网设备发送的上行信号可以仅为在PUSCH上传输的信号，从而有助于避免重要信息的丢失。
可以理解的是，由于LTE通信系统工作在FDD模式，因此，终端设备无论是否在第一上行子帧、第二上行子帧和第三上行子帧上是否在第一频段上向LTE接入网设备发送上行信号，均可以在第二频段上接收LTE接入网设备发送的下行信号。
需要说明的是，本申请实施例中，第一上行子帧可以包括一个或多个子帧，第二上行子帧也可以包括一个或多个子帧，第三上行子帧也可以为一个或多个子帧。其中，第一上行子帧包括的子帧的个数与LTE接入网设备为终端的配置相关，而第二上行子帧的个数与第一上行子帧以及NR接入网设备为终端设备配置的下行时隙的情况相关，第三上行子帧的个数与第一上行子帧以及NR接入我那个设备为终端设备配置的上行时隙和/或灵活时隙的情况有关。
以终端设备与LTE接入网设备通信时采用15KHz的子载波间隔、终端设备与NR接入网设备通信时采用30KHz的子载波间隔为例。如图12所示，LTE接入网设备为终端设备配置的上行子帧为子帧0、1、5和6。NR接入网设备为终端设备配置的上行时隙为时隙4、5、6、7，灵活时隙为8、9，下行时隙为时隙0、1、2、3、10、11、12、13、14、15、16、17、18、19。则第一上行子帧为子帧0、1、5和6。由于下行时隙中时隙0、1、2、3、10、11、12和13在时间上与第一上行子帧重叠，而下行子帧中的时隙14、15、16、17、18和19与第一上行子帧中的任一子帧未重叠，而时隙14、15、16、17、18和19在时间上与子帧7、8和9重叠，因此，第二上行子帧为子帧7、8和9。由于上行时隙中的时隙4、5、6、7以及灵活时隙中的时隙8和9均与第一上行子帧中的任一子帧在时间上为重叠，而与时隙4、5、6、7、8和9在时间上重叠的子帧为子帧2、3和4，因此第三上行子帧为子帧2、3和4。终端设备可以在0、1、5、6、7、8和9上向LTE接入网设备发送上行信号，以及当在时隙5、6、7、8和9上不向NR接入网设备发送上行信号时，可以在子帧2、3和4上向LTE接入网设备发送上行信号，从而有助于提高LTE接入网设备上行信号发送的灵活性，以及提高资源的利用率。
需要说明的是，终端设备与NR接入网设备之间进行上行通信采用的子载波间隔还可以为15KHz、60KHz、120KHz等，上述仅以子载波间隔为30KHz为例进行介绍。
本申请涉及的各个实施例可以单独使用，也可以相互组合使用，以实现不同的技术效果。

此外，还应说明的是，本申请实施例中，由于终端设备可以同时接入第一网络设备和第二网络设备，因此，如图13所示，至少一个处理器1310中包括处理器1、处理器2和处理器3，其中处理器1用于处理第一网络设备的信号，处理器2用于处理第二网络设备的信号。例如，第一网络设备为LTE接入网设备，第二网络设备为NR网络设备，则处理器1又可以称之为LTE处理器，处理器2又可以称之为NR处理器。其中，处理器3可以为应用处理器，也可以为专用处理器等。以处理器1、处理2和处理器3为例，介绍本申请实施例发送上行信号的方法。示例的，收发器1330接收到来自第一网络设备的第一指示信息后，将第一指示信息发送给处理器1，由处理器1对第一指示信息进行解析，得到第一网络设备为终端设备配置的上行时间段的配置情况，然后将第一网络设备为终端设备配置的上行时间段的情况发送给处理器3，处理器2确定第二网络设备为终端设备配置的 下行时间段的情况后，将第二网络设备为终端设备配置的下行时间段的情况发送给处理器3，由处理器3根据接收到的来自处理器2的下行时间段的配置情况和来自处理器1的上行时间段的配置情况，确定第二时间段，然后向处理器1指示在第二时间段上可以通过收发器1330向第一网络设备发送第一上行信号，处理器1当需要在第二时间段上向第一网络设备发送第一上行信号时，则可以直接在第二时间段上通过收发器1330向第一网络设备发送第一上行信号。又示例的，处理器3还可以向处理器2指示在第一时间段上不能向第二网络设备发送上行信号，以及向处理器1指示可以在第一时间段上向第二网络设备发送上行信号等。处理器1和处理器2可以根据处理器3的指示，来确定是否可以向相应的网络设备发送上行信号。
