具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
图1是本申请实施例应用的无线通信***100。该无线通信***100可以包括网络设备110、网络设备120和用户设备(user equipment，UE)130。网络设备110与网络设备120可以与UE130进行通信。网络设备110与网络设备120可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的UE130进行通信。UE130可以通过网络设备110与网络设备120接入网络(如无线网络)。可选地，该无线通信***100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例对此不作限定。
应理解，本申请实施例的技术方案可以应用于各种通信***，例如：第五代(5th generation，5G)***或新无线(new radio，NR)、长期演进(long term evolution，LTE)***、LTE频分双工(frequency division duplex，FDD)***、LTE时分双工(time division duplex，TDD)等。本申请提供的技术方案还可以应用于未来的通信***，如第六代移动通信***，又如卫星通信***，等等。
本申请实施例中的UE也可称为终端设备、接入终端、用户单元、用户站、移动站、移动台(mobile station，MS)、移动终端(mobile Terminal，MT)、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。本申请实施例中的UE可以是指向用户提供语音和/或数据连通性的设备，可以用于连接人、物和机，例如具有无线连接功能的手持式设备、车载设备等。本申请的实施例中的UE可以是手机(mobile phone)、平板电脑(Pad)、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。可选地，UE可以用于充当基站。例如，UE可以充当调度实体，其在V2X或D2D等中的UE之间提供侧行链路信号。比如，蜂窝电话和汽车利用侧行链路信号彼此通信。蜂窝电话和智能家居设备之间通信，而无需 通过基站中继通信信号。
本申请实施例中的网络设备可以是用于与UE通信的设备，该网络设备也可以称为接入网设备或无线接入网设备，如网络设备可以是基站。本申请实施例中的网络设备可以是指将UE接入到无线网络的无线接入网(radio access network，RAN)节点(或设备)。基站可以广义的覆盖如下中的各种名称，或与如下名称进行替换，比如：节点B(NodeB)、演进型基站(evolved NodeB，eNB)、下一代基站(next generation NodeB，gNB)、中继站、接入点、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、主站MeNB、辅站SeNB、多制式无线(MSR)节点、家庭基站、网络控制器、接入节点、无线节点、接入点(access piont，AP)、传输节点、收发节点、基带单元(base band unit，BBU)、射频拉远单元(Remote Radio Unit，RRU)、有源天线单元(active antenna unit，AAU)、射频头(remote radio head，RRH)、中心单元(central unit，CU)、分布式单元(distributed unit，DU)、定位节点等。基站可以是宏基站、微基站、中继节点、施主节点或类似物，或其组合。为便于理解，下文也可以将网络设备称为基站。
在一些实施例中，基站可以是固定的，也可以是移动的。例如，直升机或无人机可以被配置成充当移动基站，一个或多个小区可以根据该移动基站的位置移动。在其他示例中，直升机或无人机可以被配置成用作与另一基站进行通信的设备。在一些实施例中，基站可以是指CU或者DU，或者，基站可以包括CU和DU，或者，基站还可以包括AAU。
应理解，基站可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上；还可以部署在空中的飞机、气球和卫星上。本申请实施例中对基站和在本申请实施例中所处的场景不做限定。还应理解，本申请中的基站和UE的全部或部分功能也可以通过在硬件上运行的软件功能来实现，或者通过平台(例如云平台)上实例化的虚拟化功能来实现。
为了提高UE的数据传输速率，某些通信***引入多频段场景下的通信，例如，载波聚合(carrier aggregation，CA)、双连接(dual connectivity，DC)、LTE和NR双连接(LTE NR dual connectivity，EN-DC)等。
在多频段场景中，可以为UE配置同时工作的多个载波。例如，UE可以工作于频段(band)X与band Y组成的频段组合。其中，band X可以为频分双工(frequency division duplex，FDD)频段，band Y可以为时分双工(time division duplex，TDD)频段。
以图1为例，网络设备110可以通过band X发送下行信号，网络设备120可以通过band Y发送下行信号，UE130位于网络设备110及网络设备120的覆盖区域内，且UE130可同时与网络设备110及网络设备120进行通信，此时，UE130可以工作于band X与band  Y组成的频段组合。
但是，在UE130工作于band X与band Y组成的频段组合的情况下，band X与band Y之间的发射对接收会产生干扰。例如，band X的发射信号谐波会对band Y频段的接收信号产生干扰，同时，band Y的发射信号也会对频谱比较近的band X的接收信号产生干扰，如果干扰比较严重的话，UE可能就无法支持两个频段(或多个频段)的同时收发。
UE的同时收发能力是指：UE是否能够支持在接收一个频段信号的同时发射另外一个频段信号。UE的同时收发能力可以表示UE对两个频段间的干扰抑制能力或UE的接收解调能力。UE在一个频段组合上是否能够支持同时接收与发射(后续简称为同时收发)可以通过UE能力信息上报给基站。
若UE在某一频段组合(例如，该频段组合可以包括两个频段)上不支持同时收发，则基站在调度该频段组合的时候，需要避免UE接收一个频段信号和发射另外一个频段信号在时间上出现重叠。也就是说，基站在调度该频段组合时，对该UE只能在同一时刻发射该频段组合上的信号或在同一时刻接收该频段组合上的信号。若UE在某一频段组合(例如，该频段组合可以包括两个频段)上支持同时收发，则基站在调度该频段组合的时候，也需要避免UE接收一个频段信号和发射另外一个频段信号在时间上出现重叠超出UE的能力范围。
但是，在实际网络中，不同频段的两个(或多个)基站可能不是共站的，或两个基站之间是不同步的，这样会导致UE接收到的两个基站的下行信号之间存在一定的时间差。此外，若两个基站所处的位置不同，UE到这两个基站的距离会存在差异，则这两个基站发送的下行信号到该UE的时间也会出现时间差。
如图1所示，网络设备110与UE130之间的距离小于网络设备120与UE130之间的距离，若网络设备110与网络设备120同时向UE130发送下行信号，则网络设备110发送的下行信号会比网络设备120发送的下行信号先到达UE130。例如，如图1所示，网络设备110发送的下行信号到UE130的时间为t1，网络设备120发送的下行信号到UE130的时间为t2，则这两个网络设备发送的下行信号到UE130的时间之间的时间差为t2-t1。
如图2所示，信号110s为图1中的网络设备110与UE130之间传输的信号，信号120s为图1中的网络设备120与UE130之间传输的信号，上述时间差会导致信号110s中的上行信号(图2中用“U”表示)与信号110s中的下行信号(图2中用“D”表示)在时间上出现重叠，重叠信号间会产生干扰，当时间差比较小的时候，受影响的传输符号占比相当比较小，而当时间差比较大的时候，受影响的符号占比相对也比较大。此时，若UE在该频段组合(例如，该频段组合可以包括两个频段)上不支持同时收发，则当时间差比较大的 时候，会导致UE在该频段组合上无法正常工作。若UE在该频段组合(例如，该频段组合可以包括两个频段)上支持同时收发，当时间差超过一定值后，UE在这两个频段间的同时发射和同时接收将难以保证，从而会导致UE在该频段组合上无法正常工作。例如，如图2所示，若UE能够同时收发的最大下行时间差为33微秒(microsecond，μs)信号110s中的上行信号(图2中用“U”表示)与信号110s中的下行信号(图2中用“D”表示)的重叠部分大于33μs，则会超出UE的的同时收发能力，从而会导致UE在该频段组合上无法正常工作。
为了解决上述问题中的一个或多个，下面结合图3，对本申请实施例进行详细地举例说明。
图3是本申请实施例的通信方法的一个示意性流程图。应理解，图3示出了通信方法的步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其他操作或者图3中的各个操作的变形，或者，并不是所有步骤都需要执行，或者，这些步骤可以按照其他顺序执行。图3所示的方法300可以包括步骤S310及S320，具体如下：
S310，UE向第一基站发送第一信息。
其中，所述第一信息可以用于确定第一频段与第二频段之间的收发干扰。所述UE可以与所述第一基站在所述第一频段上进行通信，所述UE可以与第二基站在所述第二频段上进行通信。
可选地，所述第一信息也可以用于去激活(disable)所述第一频段的载波，或者，所述第一信息也可以用于调整第一下行信号在所述第一频段上的发送时间，以减少所述第一下行信号到达所述UE的时间与所述第二频段上发送的第二下行信号到达所述UE的时间之间的差值。其中，所述第一下行信号可以为所述第一基站在所述第一频段上发送的下行信号，所述第二下行信号可以为所述第二基站在所述第二频段上发送的下行信号。
可选地，所述第一信息可以包括下述各项中的至少一项：所述第一下行信号到达所述UE的时间与所述第二下行信号到达所述UE的时间、所述第一下行信号到达所述UE的时间与所述第二下行信号到达所述UE的时间之间的差值、所述差值在一个传输符号中的占比、所述差值在一个时隙(slot)中的占比、第一指示信息、所述UE的同时收发能力适用的网络场景、及所述UE能够同时收发的最大下行时间差。

可选地，所述第一门限可以是所述UE确定的、网络配置的或协议规定的。
可选地，所述第一门限可以为所述UE能够同时收发的最大下行时间差。例如，所述UE能够同时收发的最大下行时间差可以为33μs。
所述第一信息还可以用于指示所述第一频段的载波与所述第二频段的载波。
在本申请实施例中，所述第一频段和所述第二频段所在的频段组合中包含的频段可以多于两个(该频段组合中可以包含三个或三个以上频段)，此时，频段组合中可以存在多个辐载波。这种情况下，可能并不是频段组合中所有的载波之间都会产生发射对接收的干扰，而仅仅是其中的部分载波。
例如，该频段组合可以包括band X、band Y及band Z三个频段，其中，band X为主载波，band Y及band Z为辐载波。此时，若band X与band Y之间发生了发射对接收的干扰，则所述第一信息可以指示band X的载波与band Y的载波，或者，所述第一信息也可以指示band X的频段信息与band Y的频段信息，或者，所述第一信息也可以指示能够band X与band Y的其他信息。
所述第一信息还可以用于指示所述UE的同时收发能力适用的网络场景。
所述UE的同时收发能力适用的网络场景可以包括以下场景中的至少一种：共站部署场景、非共站部署场景、基站间同步场景及基站间非同步场景。
其中，共站部署场景可以指所述第一基站与所述第二基站之间共站，非共站部署场景所述第一基站与所述第二基站之间非共站，基站间同步场景可以指所述第一基站与所述第二基站之间同步(或者也可以称为定时同步)，基站间非同步场景可以指所述第一基站与所述第二基站之间非同步。
例如，所述UE的同时收发能力适用的网络场景可以为共站部署且基站间同步；或者，所述UE的同时收发能力适用的网络场景也可以为共站部署但基站间非同步；或者，所述UE的同时收发能力适用的网络场景也可以为基站间同步但非共站部署；或者，所述UE的同时收发能力适用的网络场景也可以为非共站部署且基站间非同步。
S320，所述第一基站根据所述第一信息去激活所述第一频段的载波，或者，所述第一基站根据所述第一信息调整第一下行信号在所述第一频段上的发送时间。
可选地，所述第一频段和所述第二频段中的所述第一频段的载波可以为辅载波，相应地，所述第二频段的载波可以为主载波或主要辅载波。也就是说，所述第一基站可以根据所述第一信息去激活所述第一频段和所述第二频段中的辅载波(例如，所述第一频段的载波)。
如前述实施例所述，在本申请实施例中，一个频段组合中可以包含两个以上的频段，同时，该频段组合中也可能只有部分载波之间产生发射对接收干扰，此时，基站可以去激 活(disable)产生干扰的部分载波中的辐载波，而保留没有发生干扰的主载波和辐载波。
例如，一个频段组合可以包括band X、band Y及band Z三个频段，其中，band X为主载波，band Y及band Z为辐载波。此时，若band X与band Y之间发生了发射对接收的干扰，则基站可以去激活该发射干扰的频段band Y的载波。
可选地，所述第一基站根据所述第一信息调整第一下行信号在所述第一频段上的发送时间，以减少所述第一下行信号到达所述UE的时间与所述第二频段上发送的第二下行信号到达所述UE的时间之间的差值。
在一些实施例中，在所述S320之前，所述UE还可以向基站发送第二信息，所述第二信息用于指示所述UE的同时收发能力。

可选地，所述第一基站可以确定所述差值是否超过第二门限，在所述差值大于所述第二门限的情况下，去激活所述第一频段的载波，或者，调整第一下行信号在所述第一频段上的发送时间。可选地，所述第二门限为可以是所述UE确定的、网络配置的或协议规定的。
可选地，所述第二门限可以为所述UE能够同时收发的最大下行时间差。例如，所述UE能够同时收发的最大下行时间差可以为33μs。
在一些实施例中，所述第一信息可以包括所述第一下行信号到达所述UE的时间与所述第二下行信号到达所述UE的时间之间的差值、所述差值在一个传输符号中的占比或所述差值在一个时隙中的占比。
此时，在所述S310之前，所述UE可以接收所述第一下行信号与所述第二下行信号，并确定所述第一下行信号到达所述UE的时间与所述第二下行信号到达所述UE的时间之间的差值。
可选地，所述第一基站在接收到所述第一信息后，可以根据所述第一信息去激活所述第一频段的载波，或者，调整第一下行信号在所述第一频段上的发送时间。
可选地，所述第一基站可以确定所述差值是否超过第二门限，在所述差值大于所述第二门限的情况下，去激活所述第一频段的载波，或者，调整第一下行信号在所述第一频段上的发送时间。
在一些实施例中，所述第一信息还可以包括所述第一指示信息，所述第一指示信息可以指示所述第一下行信号到达所述UE的时间与所述第二下行信号到达所述UE的时间之间的差值大于第一门限。
此时，在所述S310之前，所述UE可以接收所述第一下行信号与所述第二下行信号，确定所述第一下行信号到达所述UE的时间与所述第二下行信号到达所述UE的时间之间 的差值，并确定所述第一下行信号到达所述UE的时间与所述第二下行信号到达所述UE的时间之间的差值是否大于第一门限。
可选地，所述第一基站在接收到所述第一信息后，可以根据所述第一信息去激活所述第一频段的载波，或者，调整第一下行信号在所述第一频段上的发送时间。
可选地，所述第一基站可以在所述第一指示信息指示所述第一下行信号到达所述UE的时间与所述第二下行信号到达所述UE的时间之间的差值大于所述第一门限的情况下，去激活所述第一频段的载波，或者，调整第一下行信号在所述第一频段上的发送时间。
可选地，所述第一指示信息为1比特的指示信息。
例如，所述第一指示信息为1时，可以指示所述第一下行信号到达所述UE的时间与所述第二下行信号到达所述UE的时间之间的差值大于第一门限；所述第一指示信息为0时，可以指示所述第一下行信号到达所述UE的时间与所述第二下行信号到达所述UE的时间之间的差值小于或等于所述第一门限。当然，所述第一指示信息也可以通过其他方式进行指示，本申请实施例中对此并不限定。
在一些实施例中，所述第一信息可以包括所述UE的同时收发能力适用的网络场景。
此时，所述第一基站可以确定所述第一基站所处的网络场景与所述UE的同时收发能力适用的的网络场景是否一致。
可选地，在所述第一基站所处的网络场景与所述UE的同时收发能力适用的网络场景不同的情况下，所述第一基站可以去激活所述第一频段的载波，或者，调整第一下行信号在所述第一频段上的发送时间。
例如，假设所述第一基站所处的网络场景为所述第一基站与所述第二基站之间共站，UE发送的所述第一信息指示所述UE的同时收发能力适用的网络场景为所述第一基站与所述第二基站之间共站且同步，那么，此时所述第一基站所处的网络场景与所述UE的同时收发能力适用的网络场景不同，所述第一基站可以去激活所述第一频段的载波，或者，调整第一下行信号在所述第一频段上的发送时间。
需要说明的是，通常情况下，如果UE的同时收发能力支持非共站部署，那么就意味着其也可以支持共站部署，因为，在共站部署的多个频段间的下行信号到达UE的时间差为0。同样，如果UE的同时收发能力支持非同步部署，那么就意味着其也可以支持同步部署。可选地，若UE不上报所述UE的同时收发能力适用的网络场景，也可以默认为其没有网络部署场景的限制。
在一些实施例中，所述第一信息可以包括所述UE能够同时收发的最大下行时间差。
此时，所述第一基站可以根据所述第一信息去激活所述第一频段的载波，或者，调整 第一下行信号在所述第一频段上的发送时间。
例如，所述第一基站可以确定UE在所述第一基站对应小区中的位置，根据所述UE能够同时收发的最大下行时间差确定小区中的最坏接收位置，随后，根据所述UE在所述第一基站对应小区中的位置及最坏接收位置确定是否需要执行所述S320，即去激活所述第一频段的载波，或者，调整第一下行信号在所述第一频段上的发送时间。所述确定最坏接收位置的具体方法可以参考现有技术，本申请实施例中对此不再赘述。
