Description

一种传输干扰偏移信息的方法、装置及可读存储介质 技术领域
本公开涉及无线通信技术领域，尤其涉及一种传输干扰偏移信息的方法、装置及可读存储介质。
背景技术
在一些无线通信***中，例如在4G或者5G通信***中，为了提高传输速率和***容量，而使用多载波技术，但是在一些频段组合实现多载波传输时，会存在潜在自干扰问题。
在频段确定的情况，自干扰的大小通常与上行的发射功率有关，发射功率越大，自干扰越大，从而造成的下行的灵敏度损失也越大。
为保证载波聚合的性能，通常规定了最恶劣的情况下灵敏度损失，例如最大灵敏度减损(Maximum Sensitivity Degradation，MSD)。如3GPP 101系列标准中定义了不同频段组合的MSD最小要求。
对于一些频段组合其MSD可能会超过30dB，运营商在部署这些频段组合，可以采用完全不允许小区内的终端配置多载波模式的方式，但是会导致一些可以被配置多载波的模式终端无法配置多载波模式(如一些MSD性能较好的终端或者处在小区中心的终端由于发射功率较小，其实际的灵敏度损失也较小，从而造成无法利用多载波技术来提高速率和***容量)，也可以采用允许配置多载波模式的方式，但是由于一些灵敏度损失比较大的终端工作在多载波模式时，也会造成***性能的损失。

如图1所示，本公开实施例提供的一种传输干扰偏移信息的方法可应用于无线通信***100，该无线通信***可以包括但不限于网络设备101和用户设备102。用户设备102被配置为支持载波聚合，用户设备102可连接至网络设备101的多个载波单元，包括一个主载波单元以及一个或多个辅载波单元。
应理解，以上无线通信***100既可适用于低频场景，也可适用于高频场景。无线通信***100的应用场景包括但不限于长期演进(long term evolution，LTE)***、LTE频分双工(frequency division duplex，FDD)***、LTE时分双工(time division duplex，TDD)***、全球互联微波接入(worldwide interoperability for micro wave access，WiMAX)通信***、云无线接入网络(cloud radio access network，CRAN)***、未来的第五代(5th-Generation，5G)***、新无线(new radio，NR)通信***或未来的演进的公共陆地移动网络(public land mobile network，PLMN)***等。
以上所示用户设备102可以是用户设备(user equipment，UE)、终端(terminal)、接入终端、终端单元、终端站、移动台(mobile station，MS)、远方站、远程终端、移动终端(mobile terminal)、无线通信设备、终端代理或用户设备等。该用户设备102可具备无线收发功能，其能够与一个或多个通信***的一个或多个网络设备101进行通信(如无线通信)，并接受网络设备101提供的网络服务，这里的网络设备101包括但不限于图示基站。
其中，用户设备102可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理personal digital assistant，PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、未来5G网络中的用户设备或者未来演进的PLMN网络中的用户设备等。
网络设备101可以是接入网设备(或称接入网站点)。其中，接入网设备是指有提供网络接入功能的设备，如无线接入网(radio access network，RAN)基站等等。网络设备具体可包括基站(base station，BS)设备，或包括基站设备以及用于控制基站设备的无线资源管理设备等。该网络设备还可包括中继站(中继设备)、接入点以及未来5G网络中的基站、未来演进的PLMN网络中的基站或者NR基站等。网络设备可以是可穿戴设备或车载设备。网络设备也可以是具有通信模块的通信芯片。
比如，网络设备101包括但不限于：5G中的下一代基站(gnodeB，gNB)、LTE***中的演进型节点B(evolved node B，eNB)、无线网络控制器(radio network controller，RNC)、WCDMA***中的节点B(node B，NB)、CRAN***下的无线控制器、基站控制器(basestation controller，BSC)、GSM***或CDMA***中的基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved nodeB，或home node B，HNB)、基带单元(baseband unit，BBU)、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)或移动交换中心等。
为保证载波聚合的性能，通常规定了最恶劣的情况下灵敏度损失(MSD)不能超过一定值，如3GPP 101系列标准中就定义了不同频段组合的MSD最小要求。对一些频段组合其MSD可能会超过30dB，这样可能会造成下行完全被干扰而无法工作。上述所谓最恶劣的情况指的是配置的资源块产生的上行干扰信号的中心频点刚好与被干扰的接收信道的中心频点对齐。
考虑到在实际网络中，上述情况比较少见，因为配置的资源块是根据信道质量来决定的。如果上行干扰信号中心频点与受影响的接收信道的中心频点有一定的偏移，这样实际灵敏度损失会比MSD小很多，从而可以大大减轻自干扰带来的影响。为了考虑上述偏移，本公开中提供了多个实施例，具体如下所述。
本公开中的多载波传输可以是载波聚合传输或双链接传输。例如：双链接为EN-DC(EUTRA-NR Dual Connection)。
本公开实施例提供了一种传输干扰偏移信息的方法，图2是根据一示例性实施例示出的一种传输干扰偏移信息的方法的流程图，如图2所示，该方法包括步骤S201～S202，具体的：
步骤S201，用户设备向网络设备发送最小偏移信息。
其中，所述最小偏移信息用于指示多载波传输中上行干扰信号的中心频点和被干扰信号的中心频点之间的最小偏移量。
在一些可能的实施方式中，所述偏移量为最小偏移带宽，或者，所述最小偏移量为最小偏移带宽对应的资源块个数。
在一示例中，所述偏移量为最小偏移带宽时，最小偏移量为20MHz。
在一示例中，不同的多载波配置，最小偏移量可以不一样。如Band X与band Y作为多载波组合时，上报的最小偏移量为20MHz；而Band X与Band Z作为多载波组合时，上报的最小偏移量为25MHz。
在一示例中，所述最小偏移量为最小偏移带宽对应的资源块个数，例如最小偏移带宽15kHz的子载波对应的资源块RB个数为：100个。
步骤S202，网络设备基于接收的最小偏移信息，向用户设备发送资源配置信息。
其中，所述资源配置信息所指示的上行配置资源所对应的第一中心频点与第二中心频点之间的偏移量大于所述最小偏移量，所述第一中心频点为所述上行配置资源对应的潜在上行干扰信号的中心频点，所述第二中心频点为所述潜在上行干扰信号的下行被干扰信号的中心频点。
本公开实施例中，用户设备向网络设备发送用于指示多载波传输中上行干扰信号的中心频点和被干扰信号的中心频点之间的最小偏移量的最小偏移信息，网络设备根据接收的所述最小偏移信息，可以确定出更合理的资源配置信息，为用户设备配置可以防止自干扰的上行配置资源，从而提高降低多载波传输的自干扰，提高多载波传输的性能。
本公开实施例中，用户设备可以主动上报最小偏移信息，例如定时的或者周期性的上报最小偏移信息，无需网络设备发送上报通知消息。
本公开实施例提供了一种传输干扰偏移信息的方法，图3是根据一示例性实施例示出的一种传输干扰偏移信息的方法的流程图，如图3所示，该方法包括：
步骤S300：网络设备向所述用户设备发送用于指示所述用户设备上报所述最小偏移信 息的上报通知消息。
以及，步骤S301和步骤S302。步骤S301～S302与步骤S201～S202相应相同。
本公开实施例中，用户设备在接收到网络设备的上报通知消息后才会上报最小偏移信息，用户设备不会进行主动上报。当然，用户设备还可以基于其他触发条件以上报最小偏移信息；例如，用户设备可以基于通信协议确定的触发条件上报最小偏移信息；或是，用户设备可以定时或周期性的上报最小偏移信息；或是，用户设备可以基于预存储的配置信息，上报最小偏移信息。该触发条件可以为多种，在此不再一一赘述。
本公开实施例提供了一种传输干扰偏移信息的方法，由用户设备执行，图4是根据一示例性实施例示出的一种传输干扰偏移信息的方法的流程图，如图4所示，包括：
步骤S401，向网络设备发送最小偏移信息，所述最小偏移信息用于指示多载波传输中上行干扰信号的中心频点和被干扰信号的中心频点之间的最小偏移量。
图5示出了最小偏移信息的示意图。
在一些可能的实施方式中，所述最小偏移量为最小偏移带宽，或者，所述最小偏移量为最小偏移带宽对应的资源块个数。
在一示例中，所述偏移量为最小偏移带宽时，例如最小偏移量为20MHz。
在一示例中，不同的多载波配置，最小偏移量可以不一样。如Band X与band Y作为多载波聚合时，上报的最小偏移量为20MHz；而Band X与Band Z作为多载波聚合时，上报的最小偏移量为25MHz。
在一示例中，所述最小偏移量为最小偏移带宽对应的资源块个数，例如最小偏移带宽15kHz的子载波对应的资源块RB个数为：100个。
在一些可能的实施方式中，所述最小偏移信息包括至少一自干扰类型对应的所述最小偏移量。
在一示例中，当某个多载波配置下存在潜在自干扰的干扰类型有多种时，发送最小偏移信息需要通过索引的形式给出不同干扰类型的偏移量，例如表1所示。

其中，步骤S601与上述步骤S401相同。
在一些可能的实施方式中，还包括步骤S602，接收所述网络设备发送的资源配置信息，所述资源配置信息所指示的上行配置资源所对应的第一中心频点与第二中心频点之间的偏移量大于所述最小偏移量，所述第一中心频点为所述上行配置资源对应的潜在上行干扰信号的中心频点，所述第二中心频点为所述潜在上行干扰信号的下行被干扰信号的中心频点。
在一些可能的实施方式中，还包括步骤S600，接收网络设备发送的上报通知消息，所述上报通知消息用于指示上报所述最小偏移信息。

其中，步骤S701与上述步骤S401相同。
还包括步骤S700，向所述用户设备发送上报通知消息，所述上报通知消息用于指示所述用户设备上报所述最小偏移信息。
本公开实施例提供了一种传输干扰偏移信息的方法，由网络设备执行，图8是根据一示例性实施例示出的一种传输干扰偏移信息的方法的流程图，如图8所示，包括：
步骤S801，接收用户设备发送的最小偏移信息，所述最小偏移信息用于指示多载波传输中上行干扰信号的中心频点和被干扰信号的中心频点之间的最小偏移量。
其中，步骤S801与上述步骤S401相同。

在一些可能的实施方式中，步骤S801-1还包括，确定存在潜在自干扰，确定自干扰类型，根据所述自干扰类型确定所述上行配置资源。
其中，网络设备确定多载波传输是否存在潜在自干扰的方式包括以下三种：
方式一
基于TR37.863规范根据多载波传输中成员载波之间的频率关系确定是否存在潜在自干扰，并且在存在潜在自干扰时，确定潜在自干扰的干扰类型。
根据公式(1)计算干扰中心频率f INT：
f INT＝a×f TX1+b×f RX1+c×f TX2+d×f RX2   (1)
其中，系数a、b、c、d可以根据子规范7.3B.2中的MSD表格获得。
根据公式(2)计算干扰影响带宽BW INT：
BW INT＝a×CBW TX1+c×CBW TX2   (2)
其中，CBW表示信道带宽。
满足公式(3)时，确定上行干扰信号落入接收信号RX1的频带内从而造成自干扰。
Figure PCTCN2022092288-appb-000001
满足公式(4)时，确定上行干扰信号落入接收信号RX2的频带内从而造成自干扰。
Figure PCTCN2022092288-appb-000002
如果根据公式(3)或公式(4)确定产生了自干扰，可以进一步，根据公式(1)中的系数确定干扰类型。
在一示例中：
如果a和b中仅有一个的值为0，则干扰类型为谐波干扰，并且，谐波的次数由值为非零的系数决定。
如果a和b均不为0，则为互调干扰，互调的阶数为a的绝对值与b的绝对值之和。
方式二
根据TS38.101标准中的7.3A.4节中关于谐波干扰的表格确定多载波传输的各成员载波间是否存在谐波干扰类型的潜在自干扰。
根据TS38.101标准中的7.3A.5节中关于互调干扰的表格确定多载波传输的各成员载波间是否存在互调干扰类型的潜在自干扰。
根据TS38.101标准中的7.3A.6节中关于邻道干扰的表格确定多载波传输的各成员载波间是否存在邻道干扰类型的潜在自干扰。
方式三
根据自定义的表格确定多载波传输的各成员载波间是否存在潜在自干扰，以及确定潜在自干扰的干扰类型。
在一示例中，表2为一示例性的表格。

在一示例中，网络设备通过确定的潜在自干扰的干扰类型，并通过干扰类型确定上行BWP，使其潜在的上行干扰信号的与被干扰下行BWP信号的中心频点的实际偏移量的值大于所接收到的用户设备发送的最小偏移量。如图9所示的示意图。
其中，根据所述自干扰类型确定所述上行配置资源时可以根据自干扰类型对应的计算公式确定上行配置资源。此计算公式可以根据使用需求自行确定。
