一种干扰确定方法及其装置
本申请要求于2021年10月28日提交中国国家知识产权局、申请号为202111268498.6、申请名称为“一种干扰确定方法及其装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。

背景技术
为充分利用离散频谱资源，提出了将多段离散频谱聚合为大带宽小区的解决方案。该方案通过非连续调度的方式，使得用户可以享受大带宽体验。
终端设备中的滤波器可以过滤连续频谱以外的干扰。但是，对于多段离散频谱聚合的大带宽，由于当前离散频谱方案将多段离散频谱聚合的大带宽作为1个单载波，因此滤波器无法滤除离散频谱之间的其他频谱造成的干扰。并且也无法量化该干扰，这样可能导致终端设备工作在干扰较强的情况下，对该终端设备的性能造成较大影响。

具体实施方式
为了更好地理解本申请实施例提供的技术方案，首先对本申请实施例涉及的技术术语进行介绍。
(1)聚合带宽
聚合带宽，是由多段频谱聚合得到的一段带宽，或者，可以理解为由多段小带宽聚合得到的大带宽。负责划分频谱的机构将可用的频谱划分成段，以分配给不同的运营商使用。其中，小带宽可以为频谱划分中划分得到的其中一段频谱，大带宽可以为由多个小带宽聚合的一段频谱。需要说明的是，小带宽和大带宽为便于理解本方案所提出的概念，其中，“小”和“大”并非用于衡量频谱的宽度。在本申请实施例中，大带宽和聚合带宽可以表示相同的含义。小带宽还可以称为部分带宽(bandwidth part，BWP)。
示例性的，参见图1a所示的频谱划分示意图。其中，频谱1710.5～1785用于上行传输，频谱1805～1880用于下行传输，图1a描述了频谱1710.5～1785和1805～1880中的哪些频谱分配给运营商a，哪些分配给运营商b。图1a中，每一列中的频谱可以表示一个小带宽的频谱。如图1a所示，可以将分配给运营商a的两段小带宽聚合为一段大带宽，该大带宽的频谱宽度为10M。虽然聚合为大带宽的两段小带宽的频谱不连续，但是在调度该大带宽的情况下，可以通过非连续调度的方式，以充分利用该10M离散频谱，以提供大带宽体验。
但是，在大带宽的实际应用中可能存在4个方向干扰，见图1b所示。图1b中包括终端设备1(101)、终端设备2(103)、网络设备1(102)和网络设备2(104)。其中，方向A、方向B、方向D的干扰可以解决，但是方向C的干扰目前无法解决。该干扰较强的情况下，可能导致终端设备101发生阻塞现象，即终端设备101无法获取有用信号。终端设备101无法滤除该干扰的原因见下文。
需要说明的是，图1a所示聚合的两段小带宽的频谱不连续用于举例，在其他实现方式中，也可以将频谱连续的多段小带宽聚合为大带宽。例如，可以将分配给运营商a的频谱1805～1812.5，和分配给运营商b的频谱1812.5～1827.5，聚合为一段大带宽。频谱1805～1812.5中的1812.5，与频谱1812.5～1827.5中的1812.5相同，表示这两段频谱连续。
(2)终端设备中的2级滤波器
终端设备包括2级滤波器：射频(radio frequency，RF)滤波器和中频(intermediate frequence，IF)滤波器。其中，RF滤波器为带通滤波器，可以过滤掉目标带宽(Band)以外的信号，目标Band以内的有用信号和其他载频信号或干扰会被接收进来。IF滤波器可以根据有用信号的载波带宽自动调整滤波器宽度，过滤掉载波宽度以外的干扰。如图1c所示的2级滤波器的 工作示意图为例，图1c中的左侧为2级滤波器针对单载波的滤波过程，图1c中的右侧为2级滤波器针对离散多载波的滤波过程。其中，柱状用于表示有用信号，三角用于表示干扰。由图1c中的左侧可知，对于单载波，经过2级滤波器后，可以滤除干扰。
当前离散频谱方案将多段离散频谱聚合的大带宽作为1个单载波，RF滤波器可以过滤掉大带宽对应的最低频率和最高频率之间的Band以外的干扰。例如，以图1a中的大带宽为例，RF滤波器可以过滤掉Band(1805～1830)以外的干扰。IF滤波器根据单载波的宽度自适应调整滤波器宽度，会把其他频谱(1812.5～1827.5)的信号接收进来，其他频谱的信号为干扰。因此，通过终端设备中的2级滤波器不能滤除该其他频谱造成的干扰。又如，由图1c中的右侧可知，对于离散多载波，由于将该离散多载波作为一个单载波，因此经过2级滤波器后，仍然存在干扰未被滤除。需要说明的是，其中单载波可以理解为小带宽的载波，多载波可以理解为多个小带宽的载波，离散多载波可以理解为多个小带宽的载波的频率不连续。
在经过滤波器处理后，可以进行功率调整。功率调整过程中会将总信号功率(即有用信号+噪声的总功率)放大到模拟数字转换器(analog-to-digital converter，ADC)动态范围区间，但是在干扰强度比有用信号高较多的情况下，有用信号实际被放大的倍数较小，使得放大后的有用信号的功率很小，甚至不会被识别为有用信号，从而使得终端设备发生阻塞。并且目前也无法量化方向C的干扰，这样可能导致终端设备工作在干扰较强的情况下，对该终端设备的性能造成较大影响。
鉴于上述问题，本申请实施例通过确定终端设备在接入聚合带宽所受到的干扰，并根据该干扰向终端设备发送带宽配置信息，有利于避免终端设备工作在干扰较强的带宽下，从而有利于提高终端设备的性能。
为了更好的理解本申请实施例公开的一种干扰确定方法，下面首先对本申请实施例适用的通信系统进行描述。
请参见图1d，图1d是本申请实施例公开的一种通信系统的架构示意图。如图1d所示，该通信系统包括：终端设备101和网络设备102。
其中，终端设备101可以用于在接入第一带宽的情况下，向网络设备102发送第一带宽对应的第一信道质量信息；并在接入聚合带宽的情况下，向网络设备102发送聚合带宽对应的第二信道质量信息。其中，聚合带宽至少由第一带宽和第二带宽聚合得到，第一带宽的频谱与第二带宽的频谱之间间隔有第三带宽的频谱。
相应的，网络设备102可以用于接收来自终端设备101的第一信道质量信息和第二信道质量信息；根据第一信道质量信息和第二信道质量信息，确定终端设备101在接入聚合带宽所受到的干扰；并根据该干扰，向终端设备101发送带宽配置信息。相应的，终端设备101还可以用于接收该带宽配置信息。
通过第一信道质量信息和第二信道质量信息，确定终端设备101在接入聚合带宽所受到的干扰，可以量化干扰，并根据该干扰向终端设备101发送带宽配置信息，进一步的，该终端设备101可以根据该带宽配置信息确定工作带宽。通过这种方式，有利于终端设备工作在干扰较小的工作带宽下，即有利于避免终端设备工作在干扰较强的带宽下，从而有利于提高终端设备的性能。
其中，终端设备101可以是用户侧的一种用于接收或发射信号的实体。终端设备可以称为终端(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。终端设备可以部署在陆地上，包括室内或室外、手持或车 载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和人造卫星上等)。终端设备包括具有无线通信功能的手持式设备、车载设备、穿戴式设备或计算设备。示例性地，UE可以是手机(mobile phone)、平板电脑或带无线收发功能的电脑。终端设备还可以是虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、智能汽车(smart vehicle)终端设备、工业控制中的无线终端、无人驾驶中的无线终端、无人机、无人机控制器、远程医疗中的无线终端、智能电网中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
网络设备102可以是网络侧的一种用于发射或接收信号的实体。该网络设备可以为接入网设备，接入网设备可以为终端设备提供无线资源管理、服务质量管理、数据加密和压缩等功能。接入网设备可以是无线接入网(radio access network，RAN)设备。接入网设备可以包括基站(base station，BS)，可以是一种部署在无线接入网络中能够和终端设备进行无线通信的设备。其中，基站可能有多种形式，比如宏基站、微基站、中继站、接入点、卫星、无人机等。示例性地，接入网设备可以是第五代通信(5 th generation，5G)系统中的基站或长期演进(long term evolution，LTE)系统中的基站，其中，5G中的基站还可以称为发送接收点(transmission reception point，TRP)或下一代基站节点(next generation Node B，gNB)。本申请实施例对网络设备所采用的具体技术和具体设备形态不做限定。
本申请实施例描述的技术可用于各种通信系统，例如第五代通信(5 th generation，5G)系统，多种通信系统融合的系统，或者未来演进的通信系统，如6G通信系统。需要说明的是，本申请实施例中提及的网元名称、消息名称等用于举例，应用于不同通信系统中，网元和消息名称可以不同，本申请实施例对此不做限定。
可以理解的是，本申请实施例描述的通信系统是为了更加清楚的说明本申请实施例的技术方案，并不构成对本申请实施例提供的技术方案的限定，本领域技术人员可知，随着系统架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本申请提供的干扰确定方法及通信装置进行详细地介绍。
请参见图2，图2是本申请实施例提供的一种干扰确定方法的流程示意图，该方法包括但不限于如下步骤：
步骤S201：终端设备在接入第一带宽的情况下，向网络设备发送第一带宽对应的第一信道质量信息。相应的，网络设备接收来自终端设备的第一信道质量信息，第一信道质量信息是终端设备在接入第一带宽的情况下发送的。
其中，该第一带宽为小带宽。在一种实现方式中，终端设备可以在随机接入中接入该第一带宽，并在接入该第一带宽的情况下确定该第一带宽对应的第一信道质量信息，进而向网络设备发送该第一信道质量信息。在本申请实施例中，信道质量信息(如第一信道质量信息、第二信道质量信息)可以包括但不限于接收信号强度指示(received signal strength indication，RSSI)或信道质量指示(channel quality indication，CQI)中的一项或多项。
需要说明的是，终端设备接入某带宽，可以理解为该终端设备接入该带宽对应的小区。一个小区可以对应有一个或多个带宽，小区对应的一个或多个带宽中可以包括小带宽和聚合带宽，且小带宽和大带宽的数量均可以为一个或多个。可选的，该第一带宽可以由网络设备为终端设备配置。
在一种实现方式中，终端设备可通过如下方式确定第一带宽对应的第一信道质量信息：终端设备接收来自网络设备的第一带宽对应的小区的信道状态信息-参考信号(channel state information-reference signal，CSI-RS)；并根据该CSI-RS，测量得到该第一信道质量信息。
步骤S202：终端设备在接入聚合带宽的情况下，向网络设备发送聚合带宽对应的第二信道质量信息；其中，该聚合带宽至少由第一带宽和第二带宽聚合得到，第一带宽的频谱与第二带宽的频谱之间间隔有第三带宽的频谱。相应的，网络设备接收来自终端设备的第二信道质量信息，第二信道质量信息是终端设备在接入聚合带宽的情况下发送的。
终端设备在接入第一带宽(即小带宽)后，可以从该第一带宽切换到聚合带宽。即终端设备的工作带宽由第一带宽变为聚合带宽。
聚合带宽至少由第一带宽和第二带宽聚合得到，第一带宽的频谱与第二带宽的频谱之间间隔有第三带宽的频谱。其中，第一带宽、第二带宽和第三带宽均可以为小带宽。或者，第一带宽和第二带宽为小带宽，第三带宽的数量可以为一个或多个。第一带宽的频谱与第二带宽的频谱之间间隔有第三带宽的频谱，表明第一带宽和第二带宽的频谱不连续。此时，终端设备工作在聚合带宽下，第三带宽的信号将对终端设备造成干扰。需要说明的是，第三带宽的信号可以指承载于该第三带宽的频谱对应的载波上的信号。不同频谱对应的载波可以不同。可选的，本申请实施例中的小带宽、聚合带宽，可以为频分双工(frequency division duplexing，FDD)带宽、时分双工(timedivision duplex，TDD)带宽、标准带宽或非标带宽，本申请实施例对此不做限定。其中，标准带宽可以表示由标准协议定义的带宽，非标带宽可以表示标准协议定义的带宽以外的带宽。
在一种实现方式中，第一带宽和第二带宽均可以对应第一运营商，第三带宽对应第二运营商。换言之，第一带宽和第二带宽之间间隔有异运营商的带宽，这种情况下，终端设备在接入聚合带宽所受到的干扰为异运营商的干扰。其中，第一带宽对应第一运营商可以表示，该第一带宽分配给第一运营商，该第一运营商具有调度、分配该第一带宽的权利。在另一种实现方式中，第一带宽和第二带宽可以对应不同的运营商，例如，第一带宽对应运营商a，第二带宽对应运营商b，第三带宽对应运营商c，其中，运营商a和运营商b可以为共享带宽资源的运营商。
可选的，该第一带宽对应的小区，与该聚合带宽对应的小区可以为同一个小区。前述网络设备可以为该小区对应的网络设备(如接入网设备)。
可选的，终端设备在接入第一带宽后，可以接收来自网络设备的第一带宽配置信息，该第一带宽配置信息可以指示聚合带宽；然后，该终端设备可以根据该第一带宽配置信息，将该终端设备的工作带宽确定为聚合带宽。若接收到该第一带宽配置信息的情况下，该终端设备的工作带宽为第一带宽，那么该终端设备可以从该第一带宽切换至聚合带宽。若接收到该第一带宽配置信息的情况下，该终端设备的工作带宽为聚合带宽，那么该终端设备可以保持工作在该聚合带宽下。可选的，终端设备在接入第一带宽后，也可以自主地接入聚合带宽。
在一种实现方式中，终端设备可以向网络设备发送该终端设备的能力信息，该能力信息可以用于指示终端设备是否支持接入聚合带宽。相应的，网络设备接收来自终端设备的能力信息，并根据该能力信息，确定终端设备是否支持接入聚合带宽。在确定终端设备支持接入聚合带宽的情况下，网络设备才向该终端设备发送前述第一带宽配置信息。或者，在终端设备支持接入聚合带宽的情况下，该终端设备才尝试接聚合带宽。
在一种实现方式中，终端设备可通过如下方式确定聚合带宽对应的第二信道质量信息：终端设备接收来自网络设备的聚合带宽对应的小区的CSI-RS；并根据该CSI-RS，测量得到 该第二信道质量信息。可选的，网络设备可以在确定终端设备支持接入聚合带宽的情况下，向该终端设备发送前述第一带宽配置信息。
步骤S203：网络设备根据第一信道质量信息和第二信道质量信息，确定终端设备在接入聚合带宽所受到的干扰。
网络设备在接收到第一信道质量信息和第二信道质量信息后，可以根据第一信道质量信息和第二信道质量信息，确定终端设备在接入聚合带宽所受到的干扰。
在一种实现方式中，网络设备可以根据第二信道质量信息的评估值与第一信道质量信息的评估值之间的比值，确定终端设备在接入聚合带宽所受到的干扰的干扰值。具体的，网络设备可以将第二信道质量信息的评估值与第一信道质量信息的评估值之间的比值，确定为终端设备在接入聚合带宽所受到的干扰的干扰值。
需要说明的是，信道质量信息(如第一信道质量信息、第二信道质量信息)中包含干扰信号功率，第一信道质量信息为小带宽(第一带宽)对应的信道质量信息，第二信道质量信息为大带宽(聚合带宽)对应的信道质量信息。由前述可知，终端设备中的2级滤波器可以滤除工作在小带宽下的干扰，而不能滤除工作在聚合带宽下第三带宽带来的干扰。因此，可以用第二信道质量信息的评估值与第一信道质量信息的评估值之间的比值，来量化终端设备在接入聚合带宽所受到的干扰。值得注意的是，参考信号接收功率(reference signal receiving power，RSRP)不包含干扰信号功率，因此无法通过RSRP来量化终端设备在接入聚合带宽所受到的干扰。
信道质量信息(如第一信道质量信息、第二信道质量信息)可以包括但不限于RSSI或CQI中的一项或多项。其中，RSSI既包含有用信号功率，还包含干扰信号功率，因此，通过RSSI来量化终端设备在接入聚合带宽所受到的干扰，有利于提高量化干扰的精度。
步骤S204：网络设备根据干扰，向终端设备发送带宽配置信息。相应的，终端设备接收来自网络设备的带宽配置信息。
网络设备确定终端设备在接入聚合带宽所受到的干扰后，可以根据干扰，向终端设备发送带宽配置信息(如称为第二带宽配置信息)。终端设备可以根据该第二带宽配置信息，调整工作带宽或保持工作带宽不变。
在一种实现方式中，终端设备在工作在聚合带宽下，并向网络设备发送第二信道质量信息后，可以周期性回退到第一带宽(即周期性接入第一带宽)，测量第一带宽对应的信道质量信息，并向网络设备发送所测量得到的信道质量信息。终端设备也可以周期性切换到聚合带宽，测量该聚合带宽对应的信道质量信息，并向网络设备发送所测量得到的信道质量信息。因此，终端设备在接收到第二带宽配置信息的情况下，该终端设备的工作带宽可能为第一带宽，也可能为聚合带宽，或者可以为第一带宽和聚合带宽以外的其他带宽。
该第二带宽配置信息可以指示第一带宽或聚合带宽，第二带宽配置信息指示某带宽时，可以表示网络设备配置该终端设备的工作带宽为该带宽。在本申请实施例中，第二带宽配置信息指示第一带宽，与第二带宽配置信息用于指示终端设备的工作带宽为第一带宽表示相同含义。同理，第二带宽配置信息指示聚合带宽，与第二带宽配置信息用于指示终端设备的工作带宽为聚合带宽表示相同含义。在一种实现方式中，若终端设备在接入聚合带宽所受到的干扰的干扰值大于预设干扰值，则前述第二带宽配置信息可以用于指示终端设备的工作带宽为第一带宽。通过这种方式，有利于终端设备工作在干扰较小的第一带宽下，从而有利于提高终端设备的性能。在一种实现方式中，若终端设备在接入聚合带宽所受到的干扰的干扰值小于或等于该预设干扰值，则带宽配置信息可以用于指示终端设备的工作带宽为聚合带宽。 通过这种方式，在干扰较小的情况下，工作在聚合带宽下，有利于获取大带宽服务。其中，该预设干扰值可以由网络设备指示，或者可以由于协议约定。该预设干扰值可以是一个经验值，本申请实施例对此不做限定。
以第二带宽配置信息指示第一带宽为例，终端设备在接收到第二带宽配置信息的情况下，若该终端设备的工作带宽为聚合带宽，那么该终端设备可以从聚合带宽切换至第一带宽。若该终端设备的工作带宽为第一带宽，那么该终端设备可以保持工作在该第一带宽下。以第二带宽配置信息指示聚合带宽为例，终端设备在接收到第二带宽配置信息的情况下，若该终端设备的工作带宽为聚合带宽，那么该终端设备可以保持工作在该聚合带宽下。若该终端设备的工作带宽为第一带宽，那么该终端设备可以从第一带宽切换至聚合带宽。
在本申请实施例中，通过第一信道质量信息和第二信道质量信息，确定终端设备在接入聚合带宽所受到的干扰，可以量化干扰。并有利于根据该干扰，自适应调整终端设备工作在大带宽还是小带宽，这样有利于终端设备工作在干扰较小的工作带宽下，即有利于避免终端设备工作在干扰较强的带宽下，从而有利于提高终端设备的性能。并且，通过这种方式，有利于解决异运营商干扰造成的终端设备发生阻塞的问题，从而有利于为离散频谱聚合为虚拟大带宽提供应用可行性，也有利于为运营商共建共享提供实施可行性。进而提升资源利用率，并提升用户体验。
请参见图3，图3是本申请实施例提供的另一种干扰确定方法的流程示意图，该方法描述了网络设备如何为终端设备配置CSI-RS配置信息，以及终端设备如何根据该CSI-RS配置信息向网络设备发送聚合带宽对应的第二信道质量信息。该方法可以包括但不限于如下步骤：
步骤S301：终端设备在接入第一带宽的情况下，向网络设备发送第一带宽对应的第一信道质量信息。相应的，网络设备接收来自终端设备的第一信道质量信息，第一信道质量信息是终端设备在接入第一带宽的情况下发送的。
需要说明的是，步骤S301的执行过程可参见图2中步骤S201的具体描述，此处不再赘述。
步骤S302：网络设备向终端设备发送CSI-RS配置信息，CSI-RS配置信息包括第一带宽对应的CSI-RS的配置信息，以及第二带宽对应的CSI-RS的配置信息。相应的，终端设备接收来自网络设备的CSI-RS配置信息。
其中，该CSI-RS配置信息可用于终端设备测量聚合带宽对应的第二信道质量信息。CSI-RS配置信息可包括但不限于以下一项或多项：CSI-RS的时频位置、周期CSI-RS的周期信息。相应的，第一带宽对应的CSI-RS(如称为第一CSI-RS)的配置信息可包括但不限于以下一项或多项：第一CSI-RS的时频位置、第一CSI-RS的周期信息(若第一CSI-RS为周期CSI-RS)。第二带宽对应的CSI-RS(如称为第二CSI-RS)的配置信息可包括但不限于以下一项或多项：第二CSI-RS的时频位置、第二CSI-RS的周期信息(若第二CSI-RS为周期CSI-RS)。
在一种实现方式中，网络设备可以通过终端设备的能力信息配置该CSI-RS配置信息。终端设备可以向网络设备发送能力信息，该能力信息可以指示如下至少一项：该终端设备是否支持周期CSI-RS，该终端设备是否支持非周期CSI-RS，该终端设备支持m套周期CSI-RS，该终端设备支持n套非周期CSI-RS。其中，m和n均为整数。
可选的，聚合带宽包括的小带宽数量用z(z>＝2)表示，若m>＝z，则网络设备可以为终端设备配置z套周期CSI-RS，此时，CSI-RS配置信息可以包括z套周期CSI-RS的配置信息。 若n>＝z，则网络设备可以为终端设备配置z套非周期CSI-RS，此时，CSI-RS配置信息可以包括z套非周期CSI-RS的配置信息。若m<z，则网络设备可以为终端设备配置m套周期CSI-RS，并为终端设备配置(z-m)套非周期CSI-RS，此时，CSI-RS配置信息可以包括m套周期CSI-RS的配置信息，以及(z-m)套非周期CSI-RS的配置信息。若n<z，则网络设备可以为终端设备配置n套非周期CSI-RS，并为终端设备配置(z-n)套周期CSI-RS，此时，CSI-RS配置信息可以包括n套非周期CSI-RS的配置信息，以及(z-n)套周期CSI-RS的配置信息。若m<z，则网络设备可以为聚合带宽包括的部分小带宽(如1个小带宽：第一带宽)配置1套周期CSI-RS，此时，CSI-RS配置信息可以包括1套周期CSI-RS的配置信息。需要说明的是，部分小带宽还可以为z1个小带宽，1<z1<z。相应的，此时，CSI-RS配置信息可以包括z1套周期CSI-RS的配置信息，一个小带宽对应一套周期CSI-RS的配置信息。若n<z，则网络设备可以为聚合带宽包括的部分小带宽(如1个小带宽：第二带宽)配置1套非周期CSI-RS，此时，CSI-RS配置信息可以包括1套非周期CSI-RS的配置信息。需要说明的是，部分小带宽还可以为z2个小带宽，1<z2<z。相应的，此时，CSI-RS配置信息可以包括z2套非周期CSI-RS的配置信息，一个小带宽对应一套非周期CSI-RS的配置信息。
在一种实现方式中，在网络设备为终端设备配置的CSI-RS的数量小于聚合带宽包括的小带宽数量的情况下，即CSI-RS配置信息仅为聚合带宽包括的部分小带宽配置有CSI-RS的配置信息的情况下，聚合带宽包括的另一部分小带宽对应的信道质量信息可以为配置有CSI-RS的配置信息的小带宽对应的信道质量信息，即复用已有的CSI测量结果。例如，若聚合带宽由小带宽a、小带宽b和小带宽c聚合得到，网络设备向终端设备发送的CSI-RS配置信息包括小带宽a对应的CSI-RS的配置信息，以及小带宽b对应的CSI-RS的配置信息，不包括小带宽c对应的CSI-RS的配置信息。那么终端设备可以根据小带宽b对应的CSI-RS的配置信息测量小带宽b对应的信道质量信息，并复用小带宽b对应的信道质量信息作为小带宽c对应的信道质量信息。换言之，对于未配置有CSI-RS的配置信息的小带宽(如称为小带宽1)，可以将聚合带宽中距离该小带宽1的频谱最近的频谱(该频谱为聚合带宽中的某个小带宽的频谱)的CSI测量结果，作为该小带宽1的CSI测量结果。
步骤S303：终端设备在接入聚合带宽的情况下，根据该CSI-RS配置信息向网络设备发送聚合带宽对应的第二信道质量信息；其中，该聚合带宽至少由第一带宽和第二带宽聚合得到，第一带宽的频谱与第二带宽的频谱之间间隔有第三带宽的频谱。相应的，网络设备接收来自终端设备的第二信道质量信息，第二信道质量信息是终端设备在接入聚合带宽的情况下发送的。
终端设备接收到来自网络设备的CSI-RS配置信息后，可以根据该CSI-RS配置信息，测量得到第二信道质量信息，并向网络设备发送第二信道质量信息。具体的，终端设备可以根据第一带宽对应的CSI-RS的配置信息，测量得到第一带宽对应的信道质量信息；并根据第二带宽对应的CSI-RS的配置信息，测量得到第二带宽对应的信道质量信息，即聚合带宽对应的第二信道质量信息可以包括终端设备接入聚合带宽的情况下，测量得到的第一带宽对应的信道质量信息以及第二带宽对应的信道质量信息。
需要说明的是，步骤S303的其余执行过程可参见图2中步骤S202的具体描述，此处不再赘述。
步骤S304：网络设备根据第一信道质量信息和第二信道质量信息，确定终端设备在接入聚合带宽所受到的干扰。
步骤S305：网络设备根据干扰，向终端设备发送带宽配置信息。相应的，终端设备接收 来自网络设备的带宽配置信息。
需要说明的是，步骤S304～步骤S305的执行过程可参见图2中步骤S203～步骤S204的具体描述，此处不再赘述。
在本申请实施例中，通过第一信道质量信息和第二信道质量信息，确定终端设备在接入聚合带宽所受到的干扰，可以量化干扰。并有利于根据该干扰，自适应调整终端设备工作在大带宽还是小带宽，这样有利于终端设备工作在干扰较小的工作带宽下，即有利于避免终端设备工作在干扰较强的带宽下，从而有利于提高终端设备的性能。并且，通过这种方式，有利于解决异运营商干扰造成的终端设备发生阻塞的问题，从而有利于为离散频谱聚合为虚拟大带宽提供应用可行性，也有利于为运营商共建共享提供实施可行性。进而提升资源利用率，并提升用户体验。
在一种实现方式中，终端设备可以支持聚合带宽下的多切片滤波机制，通过该机制可以滤除终端设备在接入聚合带宽所受到的干扰。终端设备支持聚合带宽下的多切片滤波机制可以表示：终端设备可以识别聚合带宽中包括的各个小带宽，并可以针对各个小带宽进行自适应滤波。针对各个小带宽进行自适应滤波表示，可以针对各个小带宽自动调整滤波器宽度，过滤掉载波宽度以外的干扰。例如，聚合带宽由第一带宽和第二带宽聚合得到，其中，第一带宽的载波宽度为5M，第二带宽的载波宽度为10M。那么终端设备可以识别出承载于第一带宽的载波上的信息，针对该信息可以将滤波器宽度自动调整为5M，使得可以滤除其他载波的干扰。同理，终端设备可以识别出承载于第二带宽的载波上的信息，针对该信息可以将滤波器宽度自动调整为10M，使得可以滤除其他载波的干扰。通过这种方式，可以从根本上解决聚合带宽下的干扰问题。
