Description

干扰消除方法及装置 技术领域
本公开涉及通信领域,具体而言,涉及一种干扰消除方法及装置。
背景技术
随着新型移动设备的增加,通信业务不断增长、网络流量持续上升,现有的无线技术已无法满足未来通信的需求。与前几代移动通信相比,第五代移动通信技术(5th Generation,简称为5G)的业务提供能量将更加丰富,而且面对多样化场景的差异化性能需求,5G很难像以往一样以某种单一技术为基础形成针对所有场景的解决方案。
在IMT2020(5G)推进组发布的5G主要技术场景、关键挑战和适用的关键技术。其中,主要应用场景包括:移动宽带、大规模技术通信和高可靠低时延通信。5G不在单纯地强调峰值速率,而是综合考虑以下技术指标:峰值速率、用户体验速率、频谱效率、移动性、时延、连接数密度、网络能量效率和流量密度。当前,制定全球统一的5G标准已成为业界共同呼声,国际电信联盟(International Telecommunication Union,简称为ITU)在2016年开展5G技术性能需求和评估方法研究,2017年底启动5G候选方案征集,2020年底完成标准制定。3GPP将承担5G国际标准技术内容的制定工作。目前,3GPP Rel-14阶段正在进行5G NR第一阶段的标准研究。其中,一个重要的研究议题是双工通信,或,灵活双工/动态时分双工(Time Division Duplex,简称为TDD)通信方式下的交叉链路干扰管理。
灵活双工/动态TDD是指每个子帧的上下行传输资源可以动态的分配。现阶段,关于灵活双工/动态TDD方式已达成如下共识,例如,RAN1#86bis次会议、RAN1#87次会议等。
针对上述结论和双工通信的设计目标,降低或消除交叉链路干扰是一个重要的研究课题。其中,同一频带/载波上传输设备通过频分复用(Frequency Division Multiplexing,简称为FDM)方式复用,或,不同频带/载波间,由于引入灵活上下行资源分配方式,而导致的工作在相邻频带/载波间的交叉链路干扰也是一个亟待解决的问题。其中,出现邻频干扰的场景可以是NR与LTE邻频共存,或,不同业务类型邻频共存,或,不同运营商之间邻频共存等。
针对相关技术中,由于灵活双工方式而带来的邻频交叉链路干扰的问题,尚未提出有 效的解决方案。

可选实施例1
本实施例提出一种降低(消除或规避)邻频场景中出现的交叉/跨链路干扰的方法。
对于相同载波/频带情况,如图2所示,传输节点在相同载波/频带上不同频域资源上传输,由于在同一时间区域上不同频域资源上传输的链路不同,从而出现相邻频域资源间的交叉/跨链路干扰。其中,该载波/频带可以是系统带宽,或子带,或RBG,或RB。该频域资源可以是子带,或RBG,或RB,或RE(s),或上述组合。在不同频域资源上工作的对象可以是以下至少之一:不同业务,或,不同运营商,或,不同系统/网络(例如,NR,LTE,NB-IoT,e/mMTC),或不同传输节点,或相同传输节点。
可选地,在同一载波/频带上,上述工作对象在频域上占用的资源可以通过以下至少之一方式确定:预定义,或,物理层专有DCI信令,或,物理层公共DCI信令,或,高层无线资源控制RRC信令,或,以上各种组合。该频域资源可以是静态配置,或,半静态配置,或,动态配置,或,上述任意组合(例如,动态和静态结合确定)。
传输链路,包括以下之一:上行链路,下行链路,backhaul链路,sidelink链路。
上述同频带/载波中出现的交叉/跨链路干扰,可以通过能量感知的方法来降低,或,消除,或,规避邻频场景中出现的交叉/跨链路干扰的方法。具体方法如下:
第一步,传输节点获取执行感知的位置。
该执行感知的位置,包括以下至少之一:时域位置,频谱位置。时域位置,包括以下至少之一:时域起始,时域长度,时域粒度,时域间隔,时域结束。频域位置,包括以下至少之一:频域起始,频域长度,频域粒度,频域间隔,频域结束。感知位置,或,构成感知位置的时域、频域位置、参数信息中至少之一可以通过以下至少之一方式确定:预定义,或,物理层专有DCI信令,或,物理层公共DCI信令,或,高层无线资源控制RRC信令,或以上各种组合。
可选地,执行感知的位置可以是以下之一:
位置一,整个载波/频带。如图3所示。即,传输设备需要检测整个传输载波/频带上的干扰情况/水平。这种方式的好处在于,传输节点能够尽可能检测整个频带上的干扰水平。缺点在于,可能降低系统的性能,或,造成资源的浪费,因为传输节点仅适用部分频带,而实际检测整个带宽上的干扰情况,从而会出现干扰检测不准确。
位置二,部分载波/频带。如图4~6所示。图4为执行感知的频域部分大于传输资源对应的频域部分的示意图。图5为执行感知的频域部分位于传输资源外对应的频域边界开始至offset偏移量之间的区域的示意图。图6为执行感知的频域部分位于传输资源对应的频域边界两端的offset区域的示意图。图7为执行感知的频域部分位于传输资源内的对应频域边界开始至offset偏移量之间的区域的示意图。
位置三,仅在自身频域资源对应的频带上执行感知。
第二步,在感知位置,执行感知操作,确定干扰情况。以及,基于干扰情况,确定/调整传输情况。
不同频带/载波,或,不同运营商,或,不同业务类型,或,不同链路,或,不同传输节点,或,不同信号/信道,或,不同的numerology配置不同的感知检测门限阈值。
相同的频带/载波上工作的传输节点,或,业务类型,或,信号/信道,或,numerology配置相同的感知检测门限阈值。
确定干扰情况,主要是利用测量感知到的能量与不同门限值比较确定。
对于感知位置为整个载波/频带情况,如图3所示。如果传输节点1和传输节点2分别为不同的运营商,此时,如何通过测量感知操作实现不同运营商之间的友好共存(即不同运营商之间的同向链路干扰,或,反向链路干扰对彼此是可接收的)?可通过不同门限值来识别,或,区别运营商信息,或者,是否运营商之间可以友好共存:
假定同运营商之间共存门限值为TH1,不同运营商之间共存门限值为TH2。包括以下至少之一操作:如果感知到的能量不大于,或,小于门限值TH1,则认为是同运营商共存,或,信道上无异运营商存在;
可选地,如果感知到的能量不大于,或,小于门限值TH1_1,则认为同运营商之间可包括以下至少之一:共存传输,干扰水平可接收,同向链路共存,同向链路干扰水平可接收;如果感知到的能量大于TH1_1,不大于或小于门限值TH1,则认为同运营商之间可包括以下至少之一:共存,干扰水平超出可接收范围,反向链路共存,同向链路干扰水平不 可接受,反向链路干扰水平在可接受范围内;
如果感知到的能量大于门限值TH1,则认为是存在异运营商共存,同运营商共存,干扰水平超出可接收范围,反向链路共存,反向链路干扰水平不可接受,同运营商间不可共存中至少之一;
如果感知到的能量大于门限值TH1,不大于或小于门限值TH2,则认为信道上有异运营商存在。可选地,可通过下面规则判断异运营商之间是否可以共存:
可选地,如果感知到的能量大于门限值TH1,不大于或小于门限值TH2_1,则认为异运营商存在,干扰水平在可接受范围之内,同向链路共存,同向链路干扰水平可接收中至少之一;如果感知到的能量大于门限值TH2_1,不大于或小于门限值TH2,则认为异运营商存在,干扰水平超出可接收范围,反向链路共存,同向链路干扰水平不可接受,反向链路干扰水平在可接受范围内中至少之一;
如果感知到的能量大于门限值TH2,则认为信道上存在异运营商,异运营商之间的干扰水平超出可接收范围,异运营商之间不可共存,反向链路干扰水平不在可接收范围之内中至少之一。
同理,上述不同门限值的方法,也可以判定同运营商中不同设备之间不同链路方向共存情况,或,不同信道/信号共存情况,或,不同业务类型共存情况,或,不同网络系统(例如,LTE网络节点,还是,NR网络,或,混合)共存情况等。
可选地,可以针对同向链路,和,反向链路设置不同的门限值。例如,如果感知到的能量不大于,或,小于门限值1,则认为是同向链路,或,同向链路间的干扰可接受;如果感知到的能量大于门限值1,则认为是反向链路,或,同向链路间的干扰不可接受;如果感知到的能量大于门限值1,不大于或小于门限值2,则认为是反向链路,或者,反向链路间干扰可接受;如果感知到的能量大于门限值2,则认为反向链路间的干扰不可接受。
对于感知位置为部分载波/频带情况,如图4~6所示。
对于图4所示,传输节点测量感知的频域资源大于传输的频域资源,此时,如果感知到能量不大于,或,小于门限值A,则认为相邻频带间可共存,或,不存在交叉/跨链路干扰;如果感知到的能量大于门限值A,不大于或小于门限值B,则认为相邻频带间存在交叉/跨链路干扰,干扰水平在允许范围之内中至少之一;如果感知到的能量大于门限值A,则认为相邻频带之间不可共存,干扰水平超出允许的范围之内中至少之一。
可选地,对于相邻频带之间存在交叉跨链路干扰,和,交叉链路干扰水平超出允许的范围中至少之一的情况,可通过以下方式至少之一解决,或,降低,或,规避相邻频带间的干扰:
方式一:在自身传输资源上不进行传输。
方式二:传输设备可以调整自身的频域位置。例如,在相邻频带之间空白一定的guard band)。以图4为例说明方式二,如图8所示,其中,guard band的大小,起始位置,结束位置,guard band位置中至少之一可通过以下至少之一确定:预定义,与干扰水平对应, 物理层DCI信令配置、触发中至少之一,高层RRC信令配置,通过上述方式配置结合物理层DCI信令触发。
例如,干扰水平a,对应guard band大小为a1,干扰水平在a和b之间,对应的guard band大小为b1,同理,依次类推,不同干扰水平,对应不同的guard band大小。可选地,guard band可以通过预定义,或,物理层DCI信令,或,高层RRC信令预先配置,实际是否生效、guard band大小中至少之一可以通过二次信令(例如,物理层DCI信令)触发。该物理层DCI信令包括专有DCI信令,和,公共DCI信令等。可选地,用于指示guard band的第一级信令,和,第二季信令中可以携带信令与guard band之间的定时关系值,定时关系值可以是大于或等于0的正整数,例如,0,1,2,3,4,5,6,7,8,9,10,等。定时关系值的粒度可以是OFDM符号,slot,mini-slot,子帧,传输单元等。
方式三:在实际传输时降低传输功率。
例如,降低自身传输资源上的发送功率。或者,仅降低一定频域范围上传输资源上的发送功率,如图9~10所示。
其中,降低的功率值,和,降低功率的频域资源(例如,频域起始位置,频域资源大小,频域资源结束位置等)中至少之一可以是预定义,或,根据干扰水平相关,或,物理层DCI信令动态指示,或,高层RRC信令配置。
可选地,干扰水平越高,降低的功率值或offset值越大,或,降低功率的频域范围越大。
方式四:调整实际传输资源上的调度/传输链路方向情况。
例如,基于能量感知,识别出相邻链路上传输的链路方向不同,则在该传输资源调整调度的下行、上行中至少之一传输节点,或者,调整自身传输链路方向。调整传输节点的准则是同小区中的终端,或,同运营商下的传输节点,或,其他组内的传输节点,或,与相邻频带上工作传输节点干扰小的传输节点。
如图11所示,如果感知到的干扰水平达成一定门限值,则通过DCI信令调整传输链路方向。其中,调整传输链路方向的控制信令可以位于传输资源开始。控制信令与传输链路之间的定时关系值可以是预定义,或,控制信令指示,或,高层RRC信令指示,或,站点之间,或,终端之间,或,基站和终端之间约定。
为了防止通知调整链路传输方向的控制信令相邻频带上的控制/数据干扰,而导致丢失控制信令情况,可通过如下至少之一方式解决:相邻频带上的控制信令位置对齐;降低相邻频带上对应控制信道位置上的发送功率;空白相邻频带上对应控制信道位置上的资源;仅在自身频带上特定资源上发送控制信息。其中,优选地,控制信道位置与相邻频带之间具有一定的频域间隔,为了防止邻频干扰。该相邻频带上的传输设备之间可以执行以下至少之一:交互控制信道位置,请求空白资源的位置,降低发送功率请求等。
方式五:在实际传输资源上采用比相邻频带更小的时域OFDM长度。例如,相邻频带配置不同的numerology。
例如,基于能量感知,配置小的OFDM长度。如图12所示。这种方式一定程度上降低了相邻链路上的交叉链路干扰,避免了连续反向链路造成的持续性的交叉链路干扰。
可选地,可利用统计性的干扰水平来调整相邻频带之间的guard band间隔大小,或,实际传输的发射功率,或,调度/传输链路情况,或,numerology。统计性干扰水平是指一定时间内统计的干扰水平超出门限值的次数,或,一定时间内特定频域资源上的干扰水平,或,一定时间内测量干扰的累计值等。如果统计性干扰水平达到一定门限值,则进行相应的调整。
对于图5所示,传输设备执行感知的频域资源位置在相邻频带上,即测量感知位置位于与自身相邻频带上的一定频域资源上。如果在相邻频带上特定频带上感知到的能量不大于,或,小于第一门限值,则认为相邻频带对自身频带干扰可接受,或,不存在相邻干扰,或,识别出当前干扰为同向链路干扰,或,同运营商干扰,或,同系统干扰。如果在相邻频带上特定频带上感知到的能量大于第一门限值,不大于或小于第二门限值,则认为相邻频带对自身有干扰,或,该干扰一定程度上会影响自身频带上的传输,或,识别出当前干扰为反向链路干扰,或,异运营商干扰,或,异系统干扰。如果在相邻频带上特定频带上感知到的能量大于第二门限值,则认为相邻频带对自身有强干扰,或,该干扰超出共存允许的条件,或,当前干扰为反向链路干扰,且干扰非常大。
可选地,根据在相邻频带上测量干扰,来调整自身发送功率,或,空置自身频带上与相邻频带连接的特定频域资源,或,调整自身传输链路方向,或,调整自身传输使用的numerology,或,向周围设备通知干扰水平信息,或,优先级信息,或,numerology信息等,使相邻频带上的传输节点调整自身发送功率,或,传输链路方向,或,空置与邻频相连的特定频域资源,或,调整传输使用的numerology,或,基于干扰水平信息,相邻频带上工作的传输节点相互调整自身发送功率,或,空置各自频带上的特定频域资源,或,协调调度或传输链路方向,或,调整统一numerology参数。
图7与图5的不同之处在于,传输设备在自身的频带上进行干扰测量,传输设备在自身频带上的感知位置上测量的是相邻频带上泄露到本传输频带上干扰大小,基于此,传输节点可以调整自身发送功率,或,空置自身频带上与相邻频带连接的特定频域资源,或,调整自身传输链路方向,或,调整自身传输使用的numerology,或,向周围设备通知干扰水平信息,或,优先级信息,或,numerology信息等,使相邻频带上的传输节点调整自身发送功率,或,传输链路方向,或,空置与邻频相连的特定频域资源,或,调整传输使用的numerology,或,基于干扰水平信息,相邻频带上工作的传输节点相互调整自身发送功率,或,空置各自频带上的特定频域资源,或,协调调度或传输链路方向,或,调整统一numerology参数。
图6是针对传输频带两端存在其他传输频带/载波情况时,传输设备可以在自身频带/载波两端之外的频域资源上测量自身频带周围的干扰水平;或者,传输设备可以在自身频带/载波内的两端的频域资源上测量相邻频带泄露到自身频带/载波上的干扰水平。上述基 于干扰水平,调整传输的方式同样适用于此。
同理,同一频带/载波上出现的相邻频带间的交叉链路干扰处理方式,同样适用于不同载波/频带(例如,相邻载波/频带)间的交叉链路干扰。
上述判断干扰水平,或,干扰类型的方法也同样适用于此,例如,可以根据干扰水平,调整自身载波,或,相邻载波上的调度(例如,通过本载波调度其他载波,即跨载波调度等),或,传输链路方向,或,发送功率,或,引入guard band等。
可选实施例2
本实施例提出一种降低,或,消除,或,规避邻频场景中出现的交叉/跨链路干扰的方法。例如,交互信息。本实施例以相邻频带/载波为例说明,通过测量方式实现降低,或,消除,或,规避相邻频带/载波间的交叉链路干扰。
上述测量主要测量的是以下三种链路上的干扰:基站-基站之间干扰;终端-终端之间干扰;基站-终端之间的干扰。
首先,定义测量干扰的资源。可选地,测量基站-基站之间干扰的资源与测量终端-终端之间干扰的资源不同,或者,相同。相邻频带/载波上测量干扰的资源位置可以对齐,或,不对齐。
上述测量干扰的资源/位置可以是特定参考信号位置,或者,特定数据信道位置,或,预定义位置,或,物理层DCI信令配置的位置,或,高层RRC信令配置位置,或,高层RRC信令配置且物理层DCI信令触发的位置。上述信令中可以携带测量干扰的资源起始位置,或,偏移量,或,资源长度/大小,或,周期,或,间隔,或,资源结束位置,或,资源数目中至少之一。
其中,参考信号,包括:下行参考信号,和,上行参考信号。例如,基于小区专有参考信号(Cell Specific Reference Signal,CRS),或,解调参考信号(Demodulation Reference Signal,DMRS),信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS),信道状态信息干扰测量(Channel State Information Interference Measurement,CSI-IM),零功率解调参考信道(Zero Power Demodulation Reference Signal,ZP-DMRS),零功率信道状态信息参考信号(Zero Power Channel State Information Reference Signal,ZP-CSI-RS),探测参考信号(Sounding Reference Signal,SRS),零功率探测参考信号(Zero Power Sounding Reference Signal,ZP-SRS),零功率或非零功率新定义参考/测量信号。
上述参考信号除了在现有协议中规定的位置发送之外,还可以在数据发送区域的之前,或,开始发送。频域上可以按照现有协议中规定的频域图样发送之外,还可以按照预定的图样位置发送。
上述数据信道中特定位置是指在数据信道传输的特定时域位置上,空置特定的频域图样不进行数据传输。
其次,在该干扰测量资源上进行干扰测量。
对于传输节点而言,执行干扰测量可以在自身的频带/载波上的测量资源上测量,或 者,可以在相邻频带上的测量资源上进行测量。优选地,不同载波/频带上的干扰测量资源在时域上是对齐的,或者,可以是不对齐。对于前者,在一个频带/载波上的测量资源上可以发送测量信号,优选地,测量信号可以是全频带/载波发送,或者,是频域上特定的资源上发送。而测量设备可以在自身工作频带/载波上的测量资源上进行能量检测,或者,信号识别来判断相邻频带/载波间的干扰水平,和,干扰源/干扰链路方向中至少之一等信息。如图13所示。
以图13为例说明,相邻频带上工作的传输节点进行干扰测量的过程。假定在载波/频带1上传输节点进行下行传输,而载波/频带2上传输节点进行上行传输,此时,对于载波/频带1上工作的传输节点而言,基站进行下行传输操作,一定程度上会对相邻频带上工作的基站的上行接收造成干扰。此时,载波/频带2上进行上行接收的基站需要在测量资源上进行干扰测量,从而判断载波/频带1上基站发送下行信号对自身的上行接收产生的干扰程度。此时,载波/频带2上的基站可以通过以下至少之一方式判断干扰水平或干扰源/干扰链路方向:
方式一:能量感知方法。
其中,测量设备可以通过接收到的能量强度来判断邻频干扰程度,或,干扰链路方向。如果接收到的能量不大于或小于第一门限值,则认为邻频干扰可以忽略,或,不存在邻频干扰,或,干扰链路为上行链路/下行链路。如果接收到能量大于第一门限值,不大于或小于第二门限值,则认为邻频干扰存在、干扰水平在可接收范围内中至少之一,或,干扰链路方向为下行链路/上行链路。如果接收到的能量大于第二门限值,则认为邻频干扰存在、干扰水平不在可接受范围内中至少之一。可选地,也可以通过一个门限值来判定当前干扰的链路方向。
方式二:测量信号识别的方法。
另一种情况是,测量设备可以通过识别接收到来自于相邻频带上发送的信号,来判断邻频干扰程度,或,干扰链路方法。优选地,工作在相邻频带/载波上的设备之间共享或交互测量信号相关信息,例如,测量信号时域位置、符号数目、时域图样、频域图样、子载波间隔、时域起始位置、频域起始位置中至少之一。不同频带,或,不同运营商,或,不同网络,或,不同业务类型,或,不同信道/信号配置相同的测量信号时域、频域中至少之一的图样,numerology中至少之一参数。
可选地,为了通过测量信号识别干扰链路方向,不同链路方向可以配置不同的测量信号频域图样、时域图样、子载波间隔等中至少之一。
可选地,测量信号中也可以携带或指示传输链路方向信息,传输期内干扰测量资源位置信息,测量信号图样信息,传输时间长度,上下行资源配比,发射功率,波束方向,正交子空间波束信息中至少之一等。
一种特殊情况在于,对于终端-终端间干扰测量,终端侧在干扰测量资源上进行测量后,需要将干扰测量结果上报给基站,由基站来决策UE的行为,或,由终端决策自身的 行为,或,基站和UE共同决策。
优选地,终端上报干扰测量结果的资源可以是由高层RRC信令配置,或,物理层DCI信令配置,或,预定义确定。终端上报给基站的干扰测量结果信息,包括以下至少之一:干扰源的子载波间隔,传输时长,链路传输方向,上下行资源配比,传输期内干扰测量资源位置信息,测量信号图样信息,发射功率,波束方向,正交子空间波束信息等。基站可以基于终端上报的信息决策以下至少之一:是否调整链路传输方向,是否指示终端提升发送功率,调整的发射功率offset值,调整numerology参数(例如,调整为与邻频相同的numerology,或,小的OFDM符号长度,或,大的子载波间隔等)等。
可选地,在传输期间,传输节点可在测量资源上进行干扰测量来调整后续传输,或,不进行测量,在测量资源上发送一些有用信息等,防止测量资源上不发送任何信息而造成资源浪费。
可选实施例3
本实施例提出一种降低,或,消除,或,规避邻频场景中出现的交叉/跨链路干扰的方法。(优先级方式)
下面将以NR与LTE在相邻频带/载波共存场景,和,不同运营商在相邻频带/载波共存场景为例说明,本实施例中主要通过优先级方式来降低,或,消除,或,规避邻频带/载波上工作的节点间的干扰的方法。实际上,所属优先级方法可以与测量、感知、调度等方法中至少之一结合使用。
场景一:NR与LTE在相邻频带/载波共存场景。
LTE是现有网络系统,而NR是新的接入技术。考虑NR设计的后向兼容性,NR设计一定程度上需要考虑现有LTE系统的传输特征。即可以配置LTE系统具有比NR系统较高的优先级。可选地,LTE系统并非始终具有比NR高的优先级,也可以在特定情况/资源上配置低于NR的优先级。
例如,在特定资源上LTE具有较高优先级,可选地,而在特定资源上NR具有较高优先级,可选地,其他资源上NR和LTE具有相同的优先级。
为了保证LTE与NR在相邻的频带上正常工作,可以按照以下之一方式:
方式一:配置LTE系统资源。在相邻频带/载波上对齐的所属配置的资源上,LTE系统具有比NR高的优先级。
该LTE系统资源可以通过半静态,或,静态,或,动态方式,或,预定义配置。
在LTE工作频带/载波上对应的资源位置处,NR在自身工作频带/载波上可以执行如下之一操作:空白/空置对齐的资源位置;调整自身工作频带带宽;在对齐的资源位置上执行干扰测量;降低发射功率;
具体NR系统如何获知配置LTE系统资源信息,可以通过LTE系统向NR系统通知方式;或,NR系统执行测量或感知操作方式;或,NR和LTE实现约定方式;或,预定义方式,或,物理层DCI信令,或,高层RRC信令获取。
可选地,NR可以在对齐的资源位置上执行空置/空白资源处理,其中,空白/空置资源可以是预定义,或,NR与LTE实现约定,或,LTE通过空口通知给NR,或,物理层DCI信令配置,或,高层RRC信令配置;或,
调整(减少)自身工作频带的带宽,其中,调整的带宽量可以是预定义确定,或,基于获知的LTE资源上传输的信息确定,或,基于干扰测量水平确定(例如,不同的干扰水平对应不同的带宽调整量),或,物理层DCI信令,或,高层RRC信令确定;或,
在对应的资源上执行干扰测量,例如,能量感知操作,如果感知到能量满足一定门限值,则NR可以在自身频带的对应位置正常传输。如果感知操作无法识别LTE系统上的传输方向,则NR在自身系统上的传输操作可能会出现交叉链路干扰。基于此,通过设置不同门限,可以识别来自于LTE系统的干扰是信道干扰,还是,信号/消息干扰。例如,如果感知到能量不大于或小于第一门限值,则认为当前干扰为信号/消息等干扰(例如,除数据信道之外的信道或信号或消息)。如果感知到的能量大于第一门限值,则认为当前信道干扰为数据信道干扰。进一步地,如果感知到的能量大于第一门限值,且不大于或小于第二门限值,则认为当前干扰为同向链路干扰。如果感知到的能量大于第二门限值,则认为当前干扰为反向链路干扰。NR系统还可以通过信号识别来确定NR载波/频带上的传输链路方向,或,上下行行资源配比。可选地,不同的信号频域图样、子载波间隔中至少之一,与传输链路方向、上下行资源配比中至少之一对应。例如,频域上奇数资源索引图样对应的上行链路,而偶数资源图样索引图样对应的下行链路。或者,子载波间隔为15kHz,对应的上下行资源配置是2U2D,而子载波间隔为30kHz,对应的是4D4U等;
优选地,在配置的LTE资源上可以发送一些重要的信道和/信号。例如,SIB,MIB,PBCH,PSS/SSS,PRACH,Paging,CSI-RS,DMRS,SRS,数据。
方式二:LTE根据需求,动态的向NR发送信息。根据LTE发送的信息,NR需要执行一些规则,以保证NR与LTE间邻频共存。
上述方式一和上述方式二中,涉及的LTE发送给NR的信息,或,资源信息,包括以下至少之一:上下行资源配置信息,子载波间隔,OFDM符号数目,CP长度,定时关系值,干扰测量位置信息,发送功率等。其中,该定时关系值,包括以下至少之一:下行授权与下行数据之间定时关系,上行授权与上行数据之间的定时关系,下行授权与上行反馈之间的定时关系。
干扰测量位置信息可以是由偏移量,周期,频域起始位置,频域间隔,频域资源的大小,频域资源数目,频域资源粒度,时域起始位置,时域间隔,时域资源的大小,时域资源数目,时域资源粒度中至少之一确定。
为了规避工作在相邻频谱上的NR与LTE间产生干扰,则NR可以执行如下至少之一操作:
操作一:在LTE工作的时间区域执行关闭/空置资源操作。类似于Small Cell ON/off操作。
操作二:基于接收到的LTE消息,调整自身的上下行资源配比。优选地,配置与LTE相同的上下行资源配比。
操作三:基于接收到的LTE消息,在反向链路资源上执行调整功率,或,执行快速的UL-to-DL转换/DL-to-UL转换,或,空置资源,或,执行干扰测量操作,或,调整资源上的传输带宽,
方式三:NR和LTE中至少之一在各自的频带/载波上传输之前,执行干扰测量。具体干扰测量方式可以参考实施例一和二所提的方法,这里同样适用。
场景二:不同运营商在相邻频带/载波共存场景。
由于不同运营商之间协调存在时延,或,交互难度大等问题,因此,对应相邻频带上工作的不同运营商场景,可以通过优先级、感知方式中至少之一来降低邻频场景下不同运营商之间干扰。
配置不同链路的优先级,该优先级可以根据业务需求,或,预定义,或,物理层DCI信令,或,高层RRC信令确定。
在灵活双工通信中,不同运营商可以根据自身的业务需求配置上下行资源配比。这样的灵活资源配置方式,将会导致工作在相邻频带/载波上的不同运营商之间存在交叉链路干扰。基于此,可以设定某一个链路方向具有较高优先级。当设备或运营商检测到预设的高优先级链路方向,则需要进行以下至少之一:调整上下行资源配比,对应资源上的传输方向,发送功率,空置对应资源,调整对应资源上的频域带宽。
以图14为例,图14为不同运营商工作相邻频带/载波上出现的交叉链路干扰的示意图。假定运营商1工作在频带/载波1,运营商2工作在频带/载波2。设置下行链路传输方向具有高的优先级。
可选地,在各自频带上对应位置上进行传输之前,运营商之间可以交互/协调以下至少之一:上下行资源配置信息,numerology,测量干扰资源信息,一个资源中的上下行资源配比等,或,执行测量/感知操作。上述操作的目的在于获知或确定可能出现交叉链路干扰的资源信息。从图14中可看到,出现交叉链路干扰的单元为2,4,6。
对于运营商之间交互/通知上下行资源配比信息的情况,运营商之间可以获取出现交叉链路干扰的资源信息,以及结合链路传输方向的优先级,在对应交叉链路干扰的资源位置上,低优先级的运营商,可以执行如下至少之一操作:调整传输链路方向(例如,调整成下行链路方向);调整发送功率(例如,提高发送功率);空白资源;调整传输带宽(例如,减小对应资源上频域传输带宽,即在对应时域资源位置上相邻频带/载波之间引入guard band);测量交叉链路干扰水平,根据干扰水平,决定次优先级链路方向资源上的传输情况。例如,干扰水平不大于或小于共存门限值,则低优先级链路资源上正常传输,或,调整传输功率(例如,本例中提高上行链路资源上的发送功率)。而干扰水平大于共存门限值,则放弃在低优先级链路资源上的传输,或,根据干扰水平,确定缩小带宽的尺度/量,或,确定调整功率的范围/值,或,转换链路传输方向,或,引入定向beam方式传输。
可选地,对于在对齐资源上相邻载波/频带上出现一个单向链路,而相邻的另一个是混合链路(即上下行链路混合)情况,可根据交互的上下行资源配比信息,获知该资源单元中上下行符号配比,基于此,在对应相邻频带/载波上的资源上,低优先级链路仅可调整可能存在交叉链路干扰的的符号上的传输情况,例如,转换链路传输方向,或,空白反向链路对应的符号,或,调整反向链路符号上的发送功率,或,调整传输带宽(例如,减小对应符号上频域传输带宽,即在对应时域资源位置上相邻频带/载波之间引入guard band),或,测量交叉链路干扰水平,根据干扰水平,决定次优先级链路方向资源上的传输情况。例如,干扰水平不大于或小于共存门限值,则低优先级链路资源上正常传输,或,调整传输功率(例如,本例中提高上行链路资源上的发送功率)。而干扰水平大于共存门限值,则放弃在低优先级链路资源上的传输,或,根据干扰水平,确定缩小带宽的尺度/量,或,确定调整功率的范围/值,或,转换链路传输方向,或,引入定向beam方式传输。
可选地,在不同运营商之间交互/协调信息不可行情况下,传输节点可以在测量干扰的资源上,或,在传输之前执行干扰测量,基于测量情况,获取链路传输方向信息。例如,下行链路与上行链路方向识别,利用通过检测门限值识别。或者,根据上行链路,与,下行链路方向配置不同的识别信号图样、numerology中至少之一,用于进行链路方向识别。基于检测的结果,或,测量信号的识别结果,调整自身传输。如果识别干扰是下行链路,且下行链路有高优先级,则设备调整自身载波/频带上对齐资源上的发送功率,或,转换链路传输方向,或,调整传输带宽,或,空置资源,或,采用空域定向beam方式等。
需要说明的是,在本公开中,上述干扰消除方法的实现方式还可以是上述可选实施例之间的任意组合。通过上述可选实施例之间的任意组合的方式也同样能够解决相关技术中由于灵活双工方式而带来的邻频交叉链路干扰的问题,进而达到了降低邻频交叉链路干扰的效果。
通过以上的实施方式的描述,本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现,当然也可以通过硬件,但很多情况下前者是更佳的实施方式。基于这样的理解,本公开的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来,该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中,包括若干指令用以使得一台终端设备(可以是手机,计算机,服务器,或者网络设备等)执行本公开各个实施例所述的方法。
