本公开涉及通信技术领域,尤其涉及一种交叉链路干扰测量通知方法、网络侧设备及移动通信终端。
为了获得更高的频谱效率提升,小区部署密度越来越高。双工系统可以根据小区业务状态动态配置上下行数据传输方向,但当相邻小区在同一时频资源上进行不同方向(如上行或下行)的数据传输时,容易造成TRP-TRP(基站间)和UE-UE(用户间)两种类型的交叉链路干扰(Cross-Link Interference,简称CLI),严重影响系统性能。
在现有的LTE(Long Term Evolution,长期演进)系统中,主要关注了如何避免下行传输对上行传输的基站间交叉链路干扰,并基于此提出了一些典型的干扰消除方案,如链路自适应、协调调度以及功率控制等。
但考虑到小蜂窝、室内热点等重要场景,用户间交叉链路干扰也会对系统造成严重干扰。因此,在双工系统中,已经开始讨论关于用户间交叉链路干扰测量流程的设计方案,例如通过测量相邻小区用户发送的干扰测量参考信号来进行用户间的干扰测量。然而,在现有的方案中,干扰测量参考信号被配置成周期性发送或测量,灵活度低。

请参阅图1,图1是本公开实施例提供的交叉链路干扰的示意图。在图1中,网络侧设备表现为基站,移动通信终端表现为UE(User Equipment,用户设备),但应理解的,本公开实施例并不因此限制网络侧设备和移动通信终端的表现类型。如图1所示,小区1在基站1的覆盖范围内,小区2在基站2的覆盖范围内;小区1和小区2为相邻小区;UE1位于小区1内,UE2位于小区2内。
在图1中,UE1和UE2在同一时频资源上进行不同方向的数据传输,其中,UE1进行下行(Downlink,简称DL)数据传输,UE2进行上行(Uplink,简称UL)数据传输,造成了基站间(基站1和基站2之间)和用户间(UE1 和UE2之间)的交叉链路干扰(Cross-link interference,CLI),严重影响了系统性能。
为提高系统性能,基站需要得知用户间交叉链路干扰信息,从而可以通过链路自适应、调度协调以及功率控制等方案来减少交叉链路干扰的影响。
以图1中的用户间交叉链路干扰为例,本公开实施例中的用户间交叉链路干扰测量流程可以通过如下方式实现。示例性的,图1中的UE2用于发送干扰测量参考信号;UE1用于测量UE2发送的干扰测量参考信号。
基站2可以预先向UE2发送第一配置指令,用于指示干扰测量参考信号的发送配置信息,如周期性、带宽、占用符号数、端口数、密度等,并通过基站1向UE1发送第二配置指令,用于指示干扰测量参考信号的测量配置信息,如周期性、带宽、占用符号数、端口数、密度等。这样,UE1可以根据接收到的测量配置信息对UE1发送的干扰测量参考信号进行测量,获取UE1与UE2之间的交叉链路干扰信息,并将测量结果上报给基站1,以及通过基站1发送给基站2,使得基站1和基站2均可获得用户间的交叉链路干扰信息,进而使得基站可以通过链路自适应、调度协调以及功率控制等方案来减少交叉链路干扰的影响。
本公开实施例中,为提高移动通信终端发送或测量干扰测量参考信号的灵活度,提供了一种交叉链路干扰测量通知方法,应用于网络侧设备,包括:
向移动通信终端发送携带操作变更指示信息的交叉链路干扰测量通知信令,所述操作变更指示信息用于指示对干扰测量参考信号的目标操作的变更操作。
其中,目标操作可以为发送操作或测量操作。具体地,当移动通信终端为UE2时,目标操作为发送操作;当移动通信终端为UE1时,目标操作为测量操作。
变更操作可以是关闭操作、开启操作、取消操作或推迟操作。具体地,关闭操作可以理解为直接关断目标操作的执行,但应理解的,移动通信终端在关断目标操作的执行过程中,干扰测量参考信号的配置信息依然保留,从而移动通信终端可以在接收到用于指示对干扰测量参考信号的目标操作的开启操作的操作变更指示信息后,重新恢复目标操作的执行;开启操作可以理 解为直接开启目标操作的执行;取消操作可以理解为取消一次或多次目标操作的执行,并在达到预定的取消次数之后,自行恢复目标操作的执行;推迟操作可以理解为推迟目标操作的执行时机。
需要说明的是,关闭操作和取消操作的区别在于:针对关闭操作,其目标操作的执行为被动恢复,即移动通信终端只有在接收到用于指示对干扰测量参考信号的目标操作的开启操作的操作变更指示信息后,才能恢复目标操作的执行;针对取消操作,其目标操作的执行为主动恢复,即移动通信终端在检测到目标操作的执行的取消次数达到预定的取消次数之后,可以自行恢复目标操作的执行。
这样,移动通信终端可以根据接收到的交叉链路干扰测量通知信令中携带的操作变更指示信息,开启、关闭、取消或推迟干扰测量参考信号的发送或测量操作,从而可以提高干扰测量参考信号的发送或测量的灵活度,进而节省系统资源,降低移动通信终端的功耗。
请参阅图2,图2是本公开一实施例提供的交叉链路干扰测量通知方法的流程图。本实施例提供的交叉链路干扰测量通知方法应用于网络侧设备,如图2所示,本实施例的交叉链路干扰测量通知方法包括以下步骤:
步骤201、向移动通信终端发送交叉链路干扰测量通知信令,所述交叉链路干扰测量通知信令用于指示所述移动通信终端执行第一操作或第二操作。
其中,所述第一操作为:开启或关闭干扰测量参考信号的发送或测量;
所述第二操作为:取消或推迟干扰测量参考信号的发送或测量。
本实施例中,对于发送干扰测量参考信号的移动通信终端,如图1中的UE2,则第一操作为开启或关闭干扰测量参考信号的发送;第二操作为取消或推迟干扰测量参考信号的发送。
对于测量干扰测量参考信号的移动通信终端,如图1中的UE1,则第一操作为开启或关闭干扰测量参考信号的测量;第二操作为取消或推迟干扰测量参考信号的测量。
这样,移动通信终端可以根据接收到的交叉链路干扰测量通知信令,开启、关闭、取消或推迟干扰测量参考信号的发送或测量,从而可以提高干扰测量参考信号的发送或测量的灵活度,进而节省系统资源,降低移动通信终 端的功耗。
本公开实施例中,所述交叉链路干扰测量通知信令为高层信令或层1信令。进一步地,层1信令可以通过用户组公共控制信道(UE-group common PDCCH)承载;高层信令可以通过MAC(Medium Access Control,媒体介入控制)CE(Customer Edge,用户边缘设备)或RRC(Radio Resource Control,无线资源控制)信令承载。
考虑到层1信令较高层指令具有更高的实时性。因此,可选的,所述交叉链路干扰测量通知信令用于指示所述移动通信终端执行所述第一操作时,所述交叉链路干扰测量通知信令为高层信令;所述交叉链路干扰测量通知信令用于指示所述移动通信终端执行所述第二操作时,所述交叉链路干扰测量通知信令为层1信令。从而可以提高移动通信终端执行第二操作的效率。
当然,在其他实施例中,所述交叉链路干扰测量通知信令用于指示所述移动通信终端执行所述第一操作时,所述交叉链路干扰测量通知信令也可以为层1信令;或者,所述交叉链路干扰测量通知信令用于指示所述移动通信终端执行所述第二操作时,所述交叉链路干扰测量通知信令为高层信令;本公开实施例对此不作限定。
进一步地,所述交叉链路干扰测量通知信令用于指示所述移动通信终端取消干扰测量参考信号的发送或测量时,所述交叉链路干扰测量通知信令中还携带取消的次数。应理解的,若所述交叉链路干扰测量通知信令中还携带取消的次数,则移动通信终端在解析所述交叉链路干扰测量通知信令后,取消干扰测量参考信号的发送或测量的次数与所述交叉链路干扰测量通知信令中还携带取消的次数相等。例如:所述交叉链路干扰测量通知信令中还携带取消的次数为5,则移动通信终端在解析所述交叉链路干扰测量通知信令后,取消5次干扰测量参考信号的发送或测量。
这样,移动通信终端可以根据接收到的交叉链路干扰测量通知信令,确定干扰测量参考信号的发送或测量的取消次数,从而可以提高干扰测量参考信号的发送或测量的取消次数配置的灵活性。
当然,系统也可以预定义干扰测量参考信号的发送或测量的取消次数,例如:系统可以将干扰测量参考信号的发送或测量的取消次数直接固化在网 络侧设备与移动通信终端的通信协议中。这样,移动通信终端可以直接从通信协议中读取干扰测量参考信号的发送或测量的取消次数,而不用根据网络侧设备发送的交叉链路干扰测量通知信令来确定取消次数,从而可以节约系统开销。
进一步地,所述交叉链路干扰测量通知信令用于指示所述移动通信终端推迟干扰测量参考信号的发送或测量时,所述交叉链路干扰测量通知信令中还携带偏移值。这样,移动通信终端可以根据接收到的交叉链路干扰测量通知信令,确定干扰测量参考信号的发送或测量的偏移值,从而可以提高干扰测量参考信号的发送或测量的偏移值配置的灵活性。
当然,系统也可以预定义干扰测量参考信号的发送或测量的偏移值,例如:系统可以将干扰测量参考信号的发送或测量的偏移值直接固化在网络侧设备与移动通信终端的通信协议中。这样,移动通信终端可以直接从通信协议中读取干扰测量参考信号的发送或测量的偏移值,而不用根据网络侧设备发送的交叉链路干扰测量通知信令来确定偏移值,从而可以节约系统开销。
可选的,所述偏移值的单位可以表现为时间单位或时域资源单位。进一步地,所述时域资源单位为时隙slot或OFDM(Orthogonal Frequency Division Multiplexing,正交频分复用)符号。
在本公开实施例中,网络侧设备向移动通信终端发送交叉链路干扰测量通知信令之前,可以向所述移动通信终端发送配置指令,所述配置指令用于指示所述干扰测量参考信号的配置信息。具体地,针对用于发送干扰测量参考信号的移动通信终端,网络侧设备向其发送的配置指令用于指示干扰测量参考信号的发送配置信息;针对用于测量干扰测量参考信号的移动通信终端,网络侧设备向其发送的配置指令用于指示干扰测量参考信号的测量配置信息。
其中,配置信息可以但不仅限于包括干扰测量参考信号发送或测量的周期性、带宽、占用符号数、端口数、密度等参数。这样,移动通信终端可以根据上述配置指令,来实现对干扰测量参考信号的发送或测量,从而提高发送或测量干扰测量参考信号的准确度,减少移动通信终端重新发送或测量的次数,进而降低移动通信终端的功耗。
需要说明的是,本公开实施例中的干扰测量参考信号预先被网络侧设备 配置为周期性发送或测量,但在实际的用户间干扰测量流程中,网络侧设备可以根据移动通信终端反馈的测量结果对干扰测量参考信号的发送或测量进行灵活调整,从而使得移动通信终端不需要在每个预配置的时域位置进行干扰测量参考信号的发送或测量操作,降低了移动通信终端的耗电量。
可选的,所述交叉链路干扰测量通知信令用于指示所述移动通信终端执行所述第一操作时,所述向移动通信终端发送交叉链路干扰测量通知信令的步骤,包括:
若预定时间段内用户间干扰信息的变化量小于第一门限,或预定时间段内用户间干扰信息对应的干扰级别小于第二门限,则向所述移动通信终端发送用于指示关闭干扰测量参考信号的发送或测量的交叉链路干扰测量通知指令;
若预定时间段内用户间干扰信息的变化量大于或等于第一门限,或预定时间段内用户间干扰信息对应的干扰级别大于或等于第二门限,则向所述移动通信终端发送用于指示开启干扰测量参考信号的发送或测量的交叉链路干扰测量通知指令。
本实施例中,网络侧设备可以根据移动通信终端在预设时间段内上报的用户间干扰信息,如RSRP(Reference Signal Receiving Power,参考信号接收功率)或RSRQ(Reference Signal Receiving Quality,参考信号接收质量)来判断用户间交叉链路干扰情况。
具体地,可以将预定时间段内用户间干扰信息的变化量与第一门限进行比较,或者,先确定预定时间段内用户间干扰信息对应的干扰级别,再将干扰级别与第二门限进行比较,以根据比较结果,决定是否向移动通信终端发送用于指示关闭干扰测量参考信号的发送或测量的交叉链路干扰测量通知指令。
若预定时间段内用户间干扰信息的变化量小于第一门限,或预定时间段内用户间干扰信息对应的干扰级别小于第二门限,说明用户间干扰信息的变化较小或者用户间交叉链路干扰较小,移动通信终端继续周期性发送或测量干扰测量参考信号的意义不大。因此,为降低干扰测量中干扰测量参考信号的发送或测量开销,以及用户间干扰信息的反馈开销,有效提高系统性能, 网络侧设备可以向所述移动通信终端发送用于指示关闭干扰测量参考信号的发送或测量的交叉链路干扰测量通知指令,以指示移动通信终端在解析交叉链路干扰测量通知指令后,可以直接关断干扰测量参考信号的发送或测量,进而降低移动通信终端的功耗。
但应理解的,移动通信终端在关闭测量参考信号的发送或测量后,干扰测量参考信号的配置信息依然保留,从而移动通信终端可以在接收到用于指示开启干扰测量参考信号的发送或测量的交叉链路干扰测量通知指令后,开启测量参考信号的发送或测量。
本实施例中,若网络侧设备检测到预定时间段内用户间干扰信息的变化量大于或等于第一门限,或预定时间段内用户间干扰信息对应的干扰级别大于或等于第二门限,说明用户间干扰信息的变化较大或者用户间交叉链路干扰较大。因此,网络侧设备可以向所述移动通信终端发送用于指示开启干扰测量参考信号的发送或测量的交叉链路干扰测量通知指令,以指示移动通信终端在解析交叉链路干扰测量通知指令后,可以直接开启干扰测量参考信号的发送或测量,从而网络侧设备可以根据移动通信终端反馈的用户间干扰信息,通过链路自适应、调度协调以及功率控制等方案来减少交叉链路干扰的影响,提高系统性能。
当然,网络侧设备也可以根据移动通信终端在小区的位置来决定是否向移动通信终端发送用于指示关闭干扰测量参考信号的发送或测量的交叉链路干扰测量通知指令。例如:若移动通信终端位于小区中心,移动通信终端能检测到的信号强度大,则可以向所述移动通信终端发送用于指示关闭干扰测量参考信号的发送或测量的交叉链路干扰测量通知指令;若移动通信终端位于小区边缘,移动通信终端能检测到的信号强度小,则可以向所述移动通信终端发送用于指示开启干扰测量参考信号的发送或测量的交叉链路干扰测量通知指令。
为方便理解,以网络侧设备为图1中的基站2、移动通信终端为图1中的UE2为例进行说明。请一并参阅图3和图4,在图3和图4中,基站2预先配置UE2周期性发送干扰测量参考信号(以下简称SRS),即UE2在每个slot(时隙)上发送SRS,且在时域上SRS位于每个slot的倒数第三个符号 (symbol)上,在频域上SRS覆盖所有子载波,即占用一个符号。
在图3中,UE2未接收到网络侧设备发送的交叉链路干扰测量通知信令,则如图3所示,每个slot上都正常发送SRS。
而在图4中,UE2在slot2预配置发送SRS的时机之后,slot3预配置发送SRS的时机之前,接收到基站2在得知UE2位于小区中心或者UE1-UE2之间的交叉链路干扰较小时,通过高层信令发送的用于指示关闭干扰测量参考信号的发送的第一交叉链路干扰测量通知指令401;在slot4预配置发送SRS的时机之后,slot5预配置发送SRS的时机之前,接收到基站2在得知UE2位于小区边缘或者UE1-UE2之间的交叉链路干扰较大时,通过高层信令发送的用于指示开启干扰测量参考信号的发送的第二交叉链路干扰测量通知指令402。因此,如图4所示,UE2发送干扰测量参考信号的过程被划分为三个阶段,分别为第一阶段41、第二阶段42以及第三阶段43。
在第一阶段41中,由于UE2未接收到基站2发送的交叉链路干扰测量通知信令,因此,第一阶段41中的每个slot上都正常发送SRS;在第二阶段42中,由于UE2接收到基站2发送的第一交叉链路干扰测量通知指令401,因此,第二阶段42中的每个slot上都关断SRS的发送,但UE2的每个slot上的配置信息依然保留;在第三阶段43中,由于UE2接收到基站2发送的第二交叉链路干扰测量通知指令402,因此,第三阶段43中的每个slot重新开启SRS的发送。
可见,图4中UE2在第二阶段42包括的slot上停止了SRS的发送,从而相比于图3中UE2在每个slot上都正常发送SRS,可以有效降低系统资源开销,以及UE2的耗电量。
同样的,网络侧设备也可以以相同的方式通知移动通信终端开启或关闭对测量参考信号的测量,具体可参考上述描述,为避免重复,在此不再赘述。
可选的,所述交叉链路干扰测量通知信令用于指示所述移动通信终端执行所述第二操作时,所述向移动通信终端发送交叉链路干扰测量通知信令的步骤,包括:
若预定时间段内用户间干扰信息的变化量小于第三门限,或预定时间段内用户间干扰信息对应的干扰级别小于第四门限,或所述干扰测量参考信号 与其他信号存在资源冲突,则向所述移动通信终端发送指示取消或推迟干扰测量参考信号的发送或测量的交叉链路干扰测量通知信令。
其中,本步骤中“若预定时间段内用户间干扰信息的变化量小于第三门限,或预定时间段内用户间干扰信息对应的干扰级别小于第四门,限则向所述移动通信终端发送指示取消或推迟干扰测量参考信号的发送或测量的交叉链路干扰测量通知信令”与上述可选步骤中“若预定时间段内用户间干扰信息的变化量小于第一门限,或预定时间段内用户间干扰信息对应的干扰级别小于第二门限,则向所述移动通信终端发送用于指示关闭干扰测量参考信号的发送或测量的交叉链路干扰测量通知指令”的实现方式类似。
为方便理解,以网络侧设备为图1中的基站2、移动通信终端为图1中的UE2为例进行说明。请一并参阅图5a和图5b,在图5a和图5b中,基站2预先配置UE2周期性发送干扰测量参考信号(以下简称SRS),即UE2在每个slot(时隙)上发送SRS,且在时域上SRS位于每个slot的倒数第三个符号(symbol)上,在频域上SRS覆盖所有子载波,即占用一个符号。
在图5a和图5b中,UE2在slot2预配置发送SRS的时机之后,slot3预配置发送SRS的时机之前,接收到基站2在得知UE2位于小区中心或UE1-UE2之间的交叉链路干扰较小时,通过用户组公共控制信道承载的层1信令发送的用于指示取消干扰测量参考信号的发送的第三交叉链路干扰测量通知指令501。因此,如图5a和图5b所示,UE2发送干扰测量参考信号的过程被划分为两个阶段,分别为第四阶段51、第五阶段52以及第六阶段53。
在第四阶段51中,由于UE2未接收到基站2发送的交叉链路干扰测量通知信令,因此,第四阶段51中的每个slot上都正常发送SRS;在第五阶段52中,由于UE2接收到基站2发送的第三交叉链路干扰测量通知指令501,因此,第五阶段52中的每个slot上都取消SRS的发送;在第六阶段53中,由于UE2的取消发送干扰测量参考信号的次数达到预定次数后次数,因此,第六阶段53中的每个slot上都重新恢复SRS的正常发送。
图5a和图5b的区别在于,图5a中UE2取消1次干扰测量参考信号发送,图5b中UE2取消2次干扰测量参考信号发送。应理解的,UE2干扰测量参考信号发送的取消次数可以由交叉链路干扰测量通知信令指定,也可以 由网络设备或移动通信终端预先设置。
可见,图5a和图5b中UE2在第五阶段52包括的slot上停止了SRS的发送,从而相比于图3中UE2在每个slot上都正常发送SRS,可以有效降低系统资源开销,以及UE2的耗电量。
另外,相比于图4中的第三阶段43中SRS的正常发送为被动恢复,图5a和图5b中的第六阶段53中SRS的正常发送为主动恢复,从而可以有效节约系统信令开销。
同样的,网络侧设备也可以以相同的方式通知移动通信终端取消或推迟对测量参考信号的测量,具体可参考上述描述,为避免重复,在此不再赘述。
另外,相比于上述可选步骤中网络侧设备指示移动通信终端关闭干扰测量参考信号的发送或测量,本可选步骤中网络侧设备指示移动通信终端取消或推迟干扰测量参考信号的发送或测量,未完全关断干扰测量参考信号的发送或测量,因此,本可选步骤中门限值的容忍度可以大于上述可选步骤中门限值的容忍度,即第三门限可以大于第一门限,第四门限可以大于第二门限。当然,第三门限也可以等于第一门限,第四门限也可以等于第二门限,本公开实施例对此不作限定。
以下对“若所述干扰测量参考信号与其他信号存在资源冲突,则向所述移动通信终端发送指示取消或推迟干扰测量参考信号的发送或测量的交叉链路干扰测量通知信令”进行说明。
本实施例中,其他信号的发送或测量优先级高于干扰测量参考信号,可以是上行信道探测参考信号、通过PUSCH(Physical Uplink Shared Channel,物理上行共享信道)传输的信号或通过PUCCH(Physical Uplink Control Channel,物理上行链路控制信道)传输的信号。因此,网络侧设备在检测到干扰测量参考信号与其他信号存在资源冲突时,向所述移动通信终端发送指示取消或测量干扰测量参考信号的发送或测量的第三交叉链路干扰测量通知信令。
为方便理解,以网络侧设备为图1中的基站2、移动通信终端为图1中的UE2为例进行说明。请一并参阅图6a和图6b,在图6a和图6b中,基站2预先配置UE2周期性发送干扰测量参考信号(以下简称SRS),即UE2在 每个slot(时隙)上发送SRS,且在时域上,在频域上SRS覆盖所有子载波,即占用一个符号。但同时在slot3的同一符号,UE2还需要同时要发送其他信号。
在图6a中,UE2在slot2预配置发送SRS的时机之后,slot3预配置发送SRS的时机之前,接收到基站2在得知UE2在slot3的同一符号还需要同时要发送其他信号时,通过用户组公共控制信道承载的层1信令发送的用于指示取消干扰测量参考信号的发送的第四交叉链路干扰测量通知指令601,则UE2可以取消slot3上的SRS发送,slot3原配置为SRS的发送符号用于其他信号的正常发送,从而可以避免信号发送冲突。
在图6b中,UE2在slot2预配置发送SRS的时机之后,slot3预配置发送SRS的时机之前,接收到基站2在得知UE2在slot3的同一符号还需要同时要发送其他信号时,通过用户组公共控制信道承载的层1信令发送的用于指示推迟干扰测量参考信号的发送的第五交叉链路干扰测量通知指令602,则UE2可以在slot3上推迟一个符号用于SRS发送,slot3原配置为SRS的发送符号用于其他信号的正常发送,从而可以避免信号发送冲突。
应理解的,slot3中用于推迟发送SRS的符号可以由交叉链路干扰测量通知信令指定,也可以由网络设备或移动通信终端预先设置,本公开实施例对此不作限定。
同样的,网络侧设备也可以以相同的方式通知移动通信终端取消或推迟对测量参考信号的测量,具体可参考上述描述,为避免重复,在此不再赘述。
当然,若干扰测量参考信号和其他信号均被配置为周期性发送或测量,但干扰测量参考信号和其他信号的配置周期不同;或者,干扰测量参考信号被配置为非周期性发送或测量,其他信号被配置为周期性发送或测量,则网络侧设备可以在检测到干扰测量参考信号和其他信号在同一时频资源上发生冲突时,向所述移动通信终端发送指示取消或推迟干扰测量参考信号的发送或测量的交叉链路干扰测量通知信令。
若干扰测量参考信号和其他信号均被配置为周期性发送或测量,且干扰测量参考信号和其他信号的配置周期相同,则网络侧设备可以在检测到干扰测量参考信号和其他信号在同一时频资源上发生冲突时,向所述移动通信终 端发送指示推迟干扰测量参考信号的发送或测量的交叉链路干扰测量通知信令,从而可以避免干扰测量参考信号和其他信号的资源冲突。
这样,移动通信终端可以根据接收到的交叉链路干扰测量通知信令,开启、关闭、取消或推迟干扰测量参考信号的发送或测量,从而可以提高干扰测量参考信号的发送或测量的灵活度,进而节省系统资源,降低移动通信终端的功耗。
需要说明的是,若干扰测量参考信号被网络侧设备配置为非周期性发送或测量,则网络侧设备可以通过DCI(Downlink Control Information,下行控制信息)触发方式指示用户发送非周期性测量参考信号,移动通信终端可以通过DCI携带的指示信息来决定是否发送或测量干扰测量参考信号。
请参阅图7,图7表示本公开又一实施例提供的系统信息传输方法的流程图,本实施例的系统信息传输方法用于移动通信终端,移动通信终端可以为用户间交叉链路测量流程中用于发送干扰测量参考信号的移动通信终端,如图1中的UE2,也可以为用户间交叉链路测量流程中用于测量干扰测量参考信号的移动通信终端,如图1中的UE1。
如图7所示,所述交叉链路干扰测量通知方法包括:
步骤701、接收网络侧设备发送的交叉链路干扰测量通知信令;
步骤702、根据所述交叉链路干扰测量通知信令,执行第一操作或第二操作;
其中,所述第一操作为:开启或关闭干扰测量参考信号的发送或测量;
所述第二操作为:取消或推迟干扰测量参考信号的发送或测量。
可选的,所述接收网络侧设备发送的交叉链路干扰测量通知信令的步骤之前,还包括:
接收所述网络侧设备发送的配置指令,所述配置指令用于指示所述干扰测量参考信号的配置信息。
可选的,所述交叉链路干扰测量通知信令为高层信令或层1信令。
可选的,所述交叉链路干扰测量通知信令用于指示所述移动通信终端执行所述第一操作时,所述交叉链路干扰测量通知信令为高层信令;
所述交叉链路干扰测量通知信令用于指示所述移动通信终端执行所述第 二操作时,所述交叉链路干扰测量通知信令为层1信令。
可选的,所述层1信令为通过用户组公共控制信道承载的信令。
可选的,所述根据所述交叉链路干扰测量通知信令,执行第一操作或第二操作的步骤,包括:
若接收到的交叉链路干扰测量通知信令用于指示所述移动通信终端执行所述第一操作,则执行所述第一操作;
若接收到的交叉链路干扰测量通知信令用于指示所述移动通信终端执行所述第二操作,则执行所述第二操作。
可选的,所述交叉链路干扰测量通知信令用于指示所述移动通信终端取消干扰测量参考信号的发送或测量时,所述交叉链路干扰测量通知信令中还携带取消的次数。
可选的,所述交叉链路干扰测量通知信令用于指示所述移动通信终端推迟干扰测量参考信号的发送或测量时,所述交叉链路干扰测量通知信令中还携带偏移值。
可选的,所述偏移值的单位为时间单位或时域资源单位。
可选的,所述时域资源单位为时隙slot或正交频分复用OFDM符号。
需要说明的是,本实施例作为与上述方法实施例对应的移动通信终端的实施方式,因此,可以参见上述方法实施例中的相关说明,且可以达到相同的有益效果。为了避免重复说明,在此不再赘述。
在上述方法实施例中,移动通信终端在接收到网络侧设备发送的交叉链路干扰测量通知信令后,才执行对干扰测量参考信号的目标操作的变更操作。然而,在某些应用场景中,如移动通信终端自主检测到干扰测量参考信号与优先级高于所述干扰测量参考信号的待发送信号存在发送资源冲突,或者移动通信终端在同一时频资源接收到干扰测量参考信号与优先级高于所述干扰测量参考信号的目标信号,或者,移动通信终端从网络侧设备接收到时隙间隔指示信息等场景,即使未接收到网络侧设备发送的交叉链路干扰测量通知信令,移动通信终端也可以自主取消或推迟所述干扰测量参考信号的发送或测量操作。具体说明如下。
请参阅图8,图8表示本公开又一实施例提供的交叉链路干扰测量控制 方法的流程图,本实施例的交叉链路干扰测量通知方法应用于移动通信终端,如图8所示,包括:
步骤801、在干扰测量参考信号与优先级高于所述干扰测量参考信号的待发送信号存在发送资源冲突时,取消或推迟所述干扰测量参考信号的发送操作。
本实施例中,移动通信终端为用户间交叉链路测量流程中用于发送干扰测量参考信号的移动通信终端,如图1中的UE2。
移动通信终端若检测到干扰测量参考信号与优先级高于所述干扰测量参考信号的待发送信号存在发送资源冲突,则可以取消所述干扰测量参考信号的发送操作,保留所述待发送信号的发送。在该应用场景中,用户间交叉链路测量流程中用于测量干扰测量参考信号的移动通信终端,如图1中的UE1,可以通过测量UE2发送的所述待发送信号,得到UE1-UE2之间的交叉链路干扰信息,并将测量结果反馈至网络侧设备。
移动通信终端若检测到干扰测量参考信号与优先级高于所述干扰测量参考信号的待发送信号存在发送资源冲突,则可以推迟所述干扰测量参考信号的发送操作,从而可以避免干扰测量参考信号与所述待发送信号的发送资源冲突。
可选的,所述待发送信号可以为上行信道探测参考信号、通过物理上行共享信道PUSCH传输的信号或通过物理上行链路控制信道PUCCH传输的信号。
本实施例中,移动通信终端可以在检测到干扰测量参考信号与优先级高于所述干扰测量参考信号的待发送信号存在发送资源冲突时,取消或推迟所述干扰测量参考信号的发送操作,从而可以提高干扰测量参考信号的发送的灵活度,进而节省系统资源,降低移动通信终端的功耗。另外,相比于图7对应的实施例,本实施例可以节约传输交叉链路干扰测量通知信令的信令开销,从而可以进一步节约系统资源。
请参阅图9,图9表示本公开又一实施例提供的交叉链路干扰测量控制方法的流程图,本实施例的交叉链路干扰测量通知方法应用于移动通信终端,如图9所示,包括:
步骤901、在同一时频资源接收到干扰测量参考信号与优先级高于所述干扰测量参考信号的目标信号时,取消或推迟所述干扰测量参考信号的测量操作。
本实施例中,移动通信终端为用户间交叉链路测量流程中用于测量干扰测量参考信号的移动通信终端,如图1中的UE1。
当UE1在同一时频资源上接收到不同信息源发送的干扰测量参考信号与优先级高于所述干扰测量参考信号的目标信号,如在同一时频资源上接收到相邻小区的第一UE2发送的优先级高于所述干扰测量参考信号的目标信号,以及该相邻小区的第二UE2发送的干扰测量参考信号时,UE1可以取消所述干扰测量参考信号的测量操作,执行对第一UE2发送的目标信号的测量操作,从而得到UE1-UE2之间的交叉链路干扰信息,并将测量结果反馈至网络侧设备;或者,UE1可以推迟所述干扰测量参考信号的测量操作,从而可以避免干扰测量参考信号与所述待发送信号的测量资源冲突。
其中,所述目标信号可以为上行信道探测参考信号、通过物理上行共享信道PUSCH传输的信号或通过物理上行链路控制信道PUCCH传输的信号。
本实施例中,移动通信终端可以在同一时频资源接收到干扰测量参考信号与优先级高于所述干扰测量参考信号的目标信号时,取消或推迟所述干扰测量参考信号的测量操作,从而可以提高干扰测量参考信号的发送的灵活度,进而节省系统资源,降低移动通信终端的功耗。另外,相比于图7对应的实施例,本实施例可以节约传输交叉链路干扰测量通知信令的信令开销,从而可以进一步节约系统资源。
请参阅图10,图10表示本公开又一实施例提供的交叉链路干扰测量控制方法的流程图,本实施例的交叉链路干扰测量通知方法应用于移动通信终端,如图10所示,包括:
步骤1001、从网络侧接收时隙格式指示消息;
步骤1002、在所述时隙格式指示消息指示帧结构配置方向发生变化时,取消干扰测量参考信号的发送操作和/或取消干扰测量参考信号的测量操作。
本实施例中,移动通信终端可以为用户间交叉链路测量流程中用于发送干扰测量参考信号的移动通信终端,如图1中的UE2,也可以为用户间交叉 链路测量流程中用于测量干扰测量参考信号的移动通信终端,如图1中的UE1。
移动通信终端从网络侧接收到时隙格式指示消息(Slot format indicator,简称SFI)后,若解析得到所述时隙格式指示消息指示帧结构配置方向发生变化,如帧结构的数据传输方向从上行变为了下行,或者,从下行变为了上行,则相邻小区在同一时频资源上的数据传输方向从不同变为了相同,用户间的交叉链路干扰较小,因此,移动通信终端可以取消干扰测量参考信号的发送操作和/或取消干扰测量参考信号的测量操作,从而可以节约系统资源,降低移动通信终端的功耗。
为方便理解,以网络侧设备为图1中的基站2、移动通信终端为图1中的UE2为例进行说明。请一并参阅图11,在图11中,基站2预先配置UE2周期性发送干扰测量参考信号(以下简称SRS),即UE2在每个slot(时隙)上发送SRS,且在时域上SRS位于每个slot的倒数第三个符号(symbol)上,在频域上SRS覆盖所有子载波,即占用一个符号。但UE2在slot2预配置发送SRS的时机之后,slot3预配置发送SRS的时机之前,接收到基站2发送的用于指示帧结构配置方向从上行变为下行的SFI指示消息的第六交叉链路干扰测量通知指令1101,则UE2可以直接取消slot3及之后的slot的干扰测量参考信号的发送,从而可以节约系统资源,降低移动通信终端的功耗。
同样的,移动通信终端也可以以相同的方式取消对测量参考信号的测量,具体可参考上述描述,为避免重复,在此不再赘述。
当然,在其他实施例中,若移动通信终端接收到网络侧设备发送的用于指示帧结构配置方向发生变化的SFI指示消息,则移动通信终端可以直接关闭干扰测量参考信号的发送操作或测量操作。
本实施例中,移动通信终端可以在同一时频资源接收到干扰测量参考信号与优先级高于所述干扰测量参考信号的目标信号时,取消或推迟所述干扰测量参考信号的测量操作,从而可以提高干扰测量参考信号的发送的灵活度,进而节省系统资源,降低移动通信终端的功耗。相比于图7对应的实施例,本实施例可以节约传输交叉链路干扰测量通知信令的信令开销,从而可以进一步节约系统资源。
