本发明实施例中,所述基站是一种部署在无线接入网中用以为UE提供无线通信功能的装置。所述基站可以包括各种形式的宏基站,微基站(或称为小站),中继站,接入点等。在采用不同的无线接入技术的***中,具备基站功能的设备的名称可能会有所不同,例如,在LTE***中,称为演进的节点B(evolved NodeB,eNB或者eNodeB),在第三代(3rd generation,3G)***中,称为节点B(Node B)等。为方便描述,本发明所有实施例中,上述为UE提供无线通信功能的装置统称为基站或BS。
本发明实施例中所涉及到的UE可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备。所述UE也可以称为移动台(mobile station,简称MS),终端(terminal),终端设备(terminal equipment),还可以包括用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能电话(smart phone)、无线数据卡、个人数字助理(personal digital assistant,PDA)电脑、平板型电脑、无线调 制解调器(modem)、手持设备(handheld)、膝上型电脑(laptop computer)、无绳电话(cordless phone)或者无线本地环路(wireless local loop,WLL)台、机器类型通信(machine type communication,MTC)终端等。为方便描述,本发明所有实施例中,上面提到的设备统称为UE。在如图1A所示的通信***中,所述UE具有和基站进行同频全双工通信的能力。在如图1B所示的通信***中,所述UE具有和基站进行灵活TDD上下行子帧配置通信的能力。
在本发明实施例提供的方案中,网络设备可以给发射节点配置用于发射的探测资源,给接收节点配置用于检测的探测资源。发射节点根据用于发射的探测资源发送探测信号,用于发射的探测资源也可以称为探测信号发送资源。接收节点根据用于检测的探测资源检测发射节点发送的探测信号,用于检测的探测资源也可以称为探测信号检测资源。这样,接收节点可以获得发射节点对其干扰情况。接收节点可以将所述检测获得的检测结果上报给网络设备,网络设备可以根据检测结果获得发射节点对接收节点的干扰情况,根据干扰情况进行协调,减少发射节点对接收节点的干扰。
本发明实施例中,所述网络设备可以为基站,或者为与所述基站连接的控制节点,或者具有资源配置,或资源调度,或干扰协调功能的任何网络侧的设备。
在本发明实施例中,当所述发射节点和接收节点都为UE时,可以由基站配置所述探测信号发送资源和所述探测信号检测资源,也可以由控制节点或其它网络设备配置所述探测信号发送资源和所述探测信号检测资源。所述基站或者控制节点还可以配置上报资源。所述基站配置这些资源后,可以将所述配置的探测信号发送资源通知给需要进行上行发射的UE,将所述探测信号检测资源通知给所述需要进行下行接收的UE。所述控制节点配置所述资源后,可以将配置的资源通知给覆盖相应UE的基站,再由基站通知给覆盖下的UE。所谓的将资源通知给UE是指使得UE可以获知所分配的资源。当所述发射节点和接收节点都为基站时,可以由控制节点配置所述探测信号发送资源和探测信号检测资源。或者,由其中的一个基站配置所述探测信号发送资源和探测信号检测资源。可选地,若所述控制节点和基站通过无线回程(backhaul)连接,所述控制节点或所述需要进行上行接收的基站还可以配置上报资源。
在本发明实施例中,所述探测信号发送资源和探测信号检测资源也可以称为探测资源。当存在多个发射节点时,所述基站或控制节点可以在相同的时域资源上以频分的方式为所述多个发射节点分别配置所述探测信号发送资源。或者,也可以以时分的方式配置所述探测信号发送资源,即可以将不同发射节点的探测信号发送资源配置在不同的时域。或者,也可以采用空分的方式分配所述探测信号发送资源,即可以将不同的发射节点的探测 信号发送资源配置在不同的空间。总之,不同的发射节点的探测信号发送资源可以在至少一个资源维度上不重叠,所述资源维度包括时域、频域或者空域等。所述探测信号发送资源在频域上最小可以以子载波粒度进行配置,例如最小可以占用一个子载波。或者,所述探测信号发送资源在频域上也可以占用多个子载波,例如,可以以资源块(resource block,RB)为粒度进行配置,或者以半个RB进行配置等。所述探测信号发送资源在时域上最小可以以符号为粒度,例如,最小可以为一个符号,也可以为多个符号,或者为一个子帧等。因此,在本发明实施例中,仅耗用少量的资源,接收节点就能够获得发射节点对自身的干扰情况。尤其是当***中涉及到的UE或基站的数量庞大时,这种优势更为明显。
在本发明实施例图1A中,基站10可以配置UE20的探测信号发送资源,配置至少一个需要进行下行接收的UE,如UE22和UE24的探测信号检测资源。基站10还可以配置至少一个需要进行下行接收的UE的上报资源。或者,也可以由与所述基站10连接的控制节点30配置所述相关资源,然后由所述基站10通知给相应的UE。参见图2A,基站10或控制节点30可以在时频资源P1中配置给UE20的探测信号发送资源。可选的,当所述基站10下有多个需要进行上行发射的UE,则可以以频分的方式从上至下依次配置每个需要进行上行发射的UE占用一个资源块。当然,在本实施例中,也可以根据***的实际需要,配置所述UE占用一个子载波或多个子载波,此处不作限制。当***中UE较少时,也可以给每个UE配置多个RB作为探测信号发送资源。其中,资源块P1a用于UE20发送探测信号,资源块P1a还可以用作其它至少一个需要进行下行接收的UE,如UE22和UE24的探测信号检测资源。在图2A所示的例子中,若基站10覆盖下需要进行上行发射的UE数量大于时频资源P1中可配置为探测信号发送资源的数量,则可选地,还可以在时频资源P2中进行配置,或者,即使时频资源P1中可配置为探测信号发送资源满足需要参与探测的UE的数量,也可以在时频资源P2或者在其它时频资源上进行配置。因此,图2A或图2B所示的时频资源P2是可选的(optional,O)。
在本发明实施例图1B中,可以由控制节点对需要进行上行发射的UE配置探测信号发送资源,对需要进行下行接收的UE配置探测信号接收资源。或者,可以由配置了不同TDD上下行子帧配置的基站中的一个基站进行探测信号发送资源的配置,将配置的探测信号发送资源的信息发送给其它基站,其它基站可以配置覆盖下UE需要进行下行接收UE的探测信号检测资源,譬如可以将给需要进行上行发射的UE配置的探测信号发送资源作为需要进行下行接收UE的探测信号检测资源,或者,也可以由其中的一个基站进行探测信号发送资源和探测信号检测资源的配置,将配置的探测信号配置资源的信息发送给其它基站。例如, 参考图2A,可以由控制节点30配置资源块P1a为所述UE20的探测信号发送资源,所述P1a还用作至少一个需要进行下行接收的UE,如UE22和UE24的探测信号检测资源。或者,也可以由基站10配置资源块P1a为所述UE20的探测信号发送资源,所述基站10将资源块P1a配置为所述UE20的探测信号发送资源的信息发送给基站12,基站12可以将资源块P1a作为至少一个需要进行下行接收的UE的探测信号检测资源。
在本发明实施例图1B中,可以由控制节点对需要进行下行发射的基站配置探测信号发送资源,对需要进行上行接收的基站配置探测信号接收资源。或者,可以由需要进行下行发射的基站进行探测信号发送资源的配置,将配置的探测信号发送资源的信息发送给需要进行上行接收的基站,该需要进行上行接收的基站可以根据接收到的配置的探测信号发送资源的信息配置探测信号检测资源。或者,所述需要进行下行发射的基站可以进行探测信号发送资源和探测信号检测资源的配置,将所述探测信号检测资源的信息发送给所述需要进行上行接收的基站。例如,参考图2B,可以由控制节点30配置资源块P1a为所述基站12的探测信号发送资源,所述P1a还用作所述基站10的探测信号检测资源。或者,也可以由基站12配置资源块P1a为自己的探测信号发送资源,所述基站12将资源块P1a配置为所述基站12的探测信号发送资源的信息发送给基站10,基站10可以将资源块P1a作为探测信号接收资源。当存在多个需要进行下行发射的基站时,则可以以频分的方式从上至下依次配置每个需要进行下行发射的基站占用一个资源块。当然,在本实施例中,也可以根据***的实际需要,配置所述基站占用一个子载波或多个子载波,此处不作限制。
在本发明实施例中,需要进行下行发射的基站的探测信号发送资源,以及需要进行上行接收的基站的探测信号接收资源也可以预先进行配置。在通信***中,可以配置在资源池中给特定范围中的多个基站进行探测信号的发送和检测。在特定范围的多个基站中,用于多个基站发送探测信号的探测信号发送资源的尺寸(size)可以是固定的,不同基站的探测信号发送资源的尺寸可以相同。该特定范围中基站都预先知道该尺寸以及所述资源池的信息。所述特定范围也可以称为基站簇,即多个基站属于同一个簇。该特定范围或基站簇中的多个基站能够被一起进行资源调度或协调。在该特定范围或基站簇中,基站可以检测其它基站所发送的探测信号。例如,在一个热点范围内配置的多个小站,多个小站之间可以被一起进行资源调度,从而分担热点范围内终端的业务。在能够检测到其它基站所发送的探测信号。探测信号发送资源的标识(identity,ID)可以和基站的标识存在对应关系。这样,对于基站簇中的每个基站而言,都知道属于自己的探测信号发送资源,即与自己的标识存在对应关系的探测信号发送资源,以及资源池的信息和探测信号发送资源的尺寸。 从而基站就可以根据资源池信息和自己的探测信号发送资源信息,以及探测信号发送资源的尺寸可以得到配置给自己的探测信号发送资源和探测信号检测资源,即在探测信号资源池中,除自己的探测信号发送资源外的资源都可以作为探测信号检测资源,从而知道检测其它基站发送探测信号的探测信号检测资源。例如,在一个基站簇中,存在ID分别为0,1,2和3的4个基站,资源池中包括频率ID为F,F+1,F+2和F+3的4个资源单位,每个资源单位的尺寸固定,资源池的信息和探测信号发送资源的尺寸信息被所述4个基站预先知道。ID为0的基站和频率ID为F的资源存在对应关系,ID为1的基站和频率ID为F+1的资源存在对应关系,ID为2的基站和频率ID为F+2的资源存在对应关系,ID为3的基站和频率ID为F+3的资源存在对应关系。则对于ID为0的基站而言,可以获知探测信号发送资源为频率ID为F的资源,探测信号检测资源可以为频率ID为F+1、F+2和F+3的资源。以此类推,ID为1、2和3的基站都可以根据这种配置关系获得自己的探测信号发送资源和探测信号检测资源。在本实施例中,所述资源池、探测信号发送资源的尺寸,以及基站和探测信号发送资源的对应关系都可以进行预先的固定的配置。或者,所述资源池、探测信号发送资源的尺寸,以及基站和探测信号发送资源的对应关系也可以由所述基站簇中的特定基站、或者由连接所述基站簇中所有基站的控制节点进行动态配置。
在本发明实施例图1B中,所述控制节点30可以配置所述UE20的探测信号发送资源,基站12的探测信号发送资源,UE22的探测信号检测资源,所述UE22的探测信号检测资源用于对UE20发送的探测信号进行检测,以及基站10的探测信号检测资源,基站10的探测信号检测资源用于对基站12发送的探测信号进行检测。或者,也可以由所述基站10或基站12来配置上述涉及的相关资源。如图3所示,所述控制节点30、基站10或者基站12可以配置资源块P1a为UE20的探测信号发送资源,资源块P1a还用于UE22的探测信号检测资源,配置资源块P1b为基站12的探测信号发送资源,所述资源块P1b还用于基站10的探测信号检测资源。所述UE20可以在资源块P1a上发送探测信号,UE22可以对所述UE发送的探测信号进行检测。所述基站12可以在资源块P1b上发送探测信号,所述基站10可以对所述基站12发送的探测信号进行检测。
在本发明实施例中,基站或控制节点还可以配置需要进行下行接收的UE的上报资源。所述基站或控制节点可以在相同的时域资源上以频分的方式配置所述上报资源。所述上报资源最小可以以子载波为粒度,例如最小可以占用一个子载波。因此,可以通过占用较少资源的方式实现需要进行下行接收的UE对检测到的探测信号的检测结果的上报。所述上报资源也可以以多个子载波为粒度。例如,在本发明实施例图1A所示通信***中,参照图4, 在时频资源R中,从上至下依次配置一个子载波分别配置给需要进行下行接收的UE,即UE22和UE24。子载波Ra和Rb分别用于UE22和UE24上报检测结果的上报资源。
可选地,对于上述上报资源,基站或控制节点还可以给不同的需要进行下行接收的UE配置相同的时频资源,在频域上可以占用一个资源块(resource block,RB),或者也可以是以子载波为粒度,譬如至少两个子载波,在时域上,可以以子帧为单位进行配置。在该相同的时频资源上,对于不同的需要进行下行接收的UE可以在码域上进行区分,即配置不同的码,以码分的方式区分不同的UE,采用频域加码域的方式进行区分配置给不同的需要进行下行接收的UE的上报资源。其中,可以采用具有正交特性的序列进行码分,例如扎道夫-朱序列(Zadoff-Chu sequence,ZC序列)(也称为广义啁啾样序列)。例如,在本发明实施例图1A或图1B所示通信***中,参照图5,在时频资源R中,资源块Rab配置给UE22和UE24,在资源块Rab中,以ZC序列a(ZCa)配置给UE22,用于发送UE22的检测结果,ZC序列b(ZCb)配置给UE24,用于发送UE24的检测结果。
在本发明实施例中,所述探测资源的周期或上报资源可以是周期性呈现,譬如周期性配置,或者被配置为周期出现。也即,所述发射节点可以周期性发送探测信号,所述接收节点进行周期性检测,并可以进行周期性上报。所述周期可以比较长,譬如为百毫秒级别,这样对于探测信号的检测和检测结果的上报而言,***资源的开销比较低,也比较适合超密集网络(ultra dense network,UDN)场景。
根据图2A、图2B或图3所示配置的探测信号发送资源对探测信号进行检测的UE,可以采用图4或图5所配置的上报资源形式将检测得到的检测结果上报给网络设备。
在配置的上报资源中,还配置有用于发送参考信号的资源,所述参考信号可以用于网络侧对上报的检测结果进行解调。
在上述图1A-图5中的L、A、P1、P2、R、a-b、Ra-Rb、Rab等是对所描述对象一种区分符号,也可以用其它任何形式的符号来标识,在本申请文件中不具有特别限定的含义。
在本发明实施例中,需要进行上行发射的UE或需要进行下行发射的基站发送的探测信号可以携带信息,譬如携带发送端的标识信息,或者发送探测信号的功率水平等。或者所述探测信号也可以不携带具体信息,此时,可将调制后待映射的符号设置为任意值(例如均设置为全1)。发送端将该符号映射至配置的探测信号发送资源上。在本发明实施例中,若所述需要进行上行发射的UE或需要进行下行发射的基站发送的探测信号不携带具有任何实际含义的信息,那么接收方只需进行基于能量的检测,无需解调解码,对接收方的要求低,该探测信号所占用的***资源也比较少,因此,可以节省***资源。
下面结合图6,对本发明实施例提供的技术方案进行说明。
在601部分,为发射节点配置探测信号发送资源,为接收节点配置探测信号检测资源。

所述分配指示信息可以以明示的方式通知配置给所述需要进行上行发射的UE的探测信号发送资源,还可以以明示的方式通知配置给需要进行下行接收的UE的探测信号检测资源,可选地,还包括配置的上报资源。例如,在图2A中,基站10可以在分配资源,即时频资源A中发送所述分配指示信息。所述分配指示信息中可以指示UE20的探测信号发送资源位于时频资源P1的资源块P1a,UE22和UE24的探测信号检测资源位于时频资源P1的资源块P1a,UE22和UE24的上报资源分别位于如图4所示的时频资源R中的子载波Ra和Rb中,或者UE22和UE24的上报资源位于如图5所示的时频资源R中的资源块Rab中,并且用于进行码分的ZC序列分别为ZCa和ZCb。对于如图1B所例举的通信***中,可以分别由基站10在分配资源A中发送分配指示信息给UE20,在分配指示信息中指示配置给UE20的探测信号发送资源。由基站12在分配资源A中发送分配指示信息给UE22和UE24,指示UE22和UE24的探测信号检测资源位于时频资源P1的资源块P1a,UE22和UE24的上报资源分别位于如图4所示的时频资源R中的子载波Ra和Rb中,或者UE22和UE24的上报资源位于如图5所示的时频资源R中的资源块Rab中,并且用于进行码分的ZC序列分别为ZCa和ZCb。需要说明的是,所述基站10使用的分配资源和所述基站12所使用的分配资源可以相同,也可以不同。
在本实施例中,对于所述发射节点为需要进行下行发射的基站,所述接收节点为需要进行上行接收的基站的情况,如图1B所例举的通信***中,控制节点将配置的探测信号发送资源通知给所述需要进行下行发射的基站,将配置的探测信号检测资源通知给所述需要进行上行接收的基站。或者,所述需要进行下行发射的基站和需要进行上行接收的基站也可以根据前述预先配置的方法,根据资源池信息、基站和探测信号发送资源的对应关系、以及探测信号发送资源的尺寸获得探测信号发送资源和探测信号检测资源。
在本发明实施例中,基站在将探测资源或上报资源通知给UE的情况中,分配资源和探测资源可以有配置的时序关系,分配资源、探测资源和上报资源可以有配置的时序关系,则分配指示信息中也可以不用包含探测资源或上报资源的时域信息。UE在接收到基站发送的分配指示信息后,根据发送分配指示信息的分配资源的时域位置以及所述配置的时序关系,就可以确定探测资源或上报资源的时域位置,并进一步根据分配指示信息中包含的探测资源和上报资源的频域位置信息,从而可以确定配置给自己的探测资源或上报资源。例如参考图2A,例如,分配资源A的时域位置为n,探测资源P1和分配资源A的时序关系为:n+k,上报资源R和探测资源P1、分配资源A的时序关系为:n+m+k。则UE若在时域位置n接收到基站发送的分配指示信息,则UE根据时序关系n+k,可以获得探测资源的时域位置n+k,并根据分配指示信息中指示的探测信号发送资源的频域位置最终获得配置的探测资源。此外,UE根据时序关系n+m+k获得上报资源R的时域位置,并根据分配指示信息中的频域信息,或者频域加码域信息获得上报资源。所述n、m和k可以表示绝对时间值,也可以表示相对时间值。或者可以表示时间单元序号对应的值,例如符号、时隙、子帧或帧的序号等,可以为整数。
在603部分中,所述发射节点在配置的探测信号发送资源上发送探测信号,所述接收节点在探测信号检测资源上对所述发射节点发送的探测信号进行检测。
所述发射节点在发送探测信号时,可采用一对多(one-to-many)的形式进行发送,或者,也可以采用广播的形式进行发送。
所述接收节点可以根据接收到的探测信号,检测发送该探测信号的发射节点对自身的干扰情况,获得检测结果。所述检测结果可以为量化的测量值,例如可以是绝对量化值,譬如直接测量接收到的探测信号的接收功率的量化值。或者,也可以将检测到的绝对量化值进行转换,获得相对量化值。譬如,预先将绝对量化值分成N(N为正整数)个范围,每个范围对应索引值,则可以根据检测得到的绝对量化值获得对应的索引值,以所述索引值作为检测结果。或者,也可以是根据预先设定的门限判断得到的结果。例如,若检测到的 探测信号的强度大于预设门限,则将检测结果记为“1”,否则,若检测到的探测信号强度小于预设门限小于预设门限,则将检测结果记为“0”。若检测到的探测信号的强度等于预设门限时,可以将检测结果记为“1”,或者也可以记为“0”。当然,也可以将探测信号强度大于预设门限时,将检测结果记为“0”,否则记为“1”。
在本发明实施例中,所述检测结果为探测信号的接收功率的量化值时,该检测结果可以为承载探测信号的资源元素(resource element,RE)上接收功率的平均值。一个RE在时域上占用一个符号,在频域上占用一个子载波。进行探测信号检测的测量节点在承载被测量节点发送的探测信号的RE上进行接收功率测量平均处理,例如,进行探测信号检测的测量节点可以在承载其它被测量节点发送的探测信号的RE上进行接收功率测量平均处理,测量节点可以在承载被测量节点发送的探测信号的RE上进行功率测量平均处理。所述承载探测信号的RE上功率的平均值可以为承载所述探测信号的RE上功率的线性平均。进行探测信号检测测量节点可以在同频或异频状态进行接收功率平均处理,对于不支持在不同频带上同时进行探测信号检测的节点,可以配置间隔(gap),在一个间隔内,在除主频带以外的一个频带上进行检测。间隔前后需要有转换保护时间,所述间隔可以根据现有***中配置的间隔,也可以配置新的间隔。对于能够支持在不同频带上同时进行探测信号检测的节点,可以在不同频带上同时进行测量。D2D UE可以在连接态进行接收功率平均处理。
在特定测量频率带宽和测量周期中用于进行接收功率平均处理的承载检测信号的RE的个数可以取决于在满足测量精度需求条件时测量节点的实现。例如,测量节点可以将承载被测量节点发送的探测信号的所有RE的功率都进行平均处理,或者,也可以将承载被测量节点发送的探测信号的所有RE中的部分RE的功率进行平均处理。
可选地,本实施例的方案还可以包括604部分。在604部分,所述接收节点将检测得到的结果在上报资源中上报给网络设备。网络设备可以获得所述接收节点上报的检测结果。
所述发射节点和接收节点分别为需要进行上行发射的UE和需要进行下行接收的UE时,若所述需要进行下行接收的UE配置了上报资源,在本发明实施例描述的应用同频全双工技术的通信***中,所述需要进行下行接收的UE可以在所述上报资源中将所述检测结果上报给基站,所述基站也可以进一步将所述检测结果上报给控制节点。例如,在图1A中,UE22或UE24可以将检测结果上报给基站10,所述基站10也可以进一步将检测结果上报给控制节点30。在本发明实施例描述的应用灵活TDD上下行子帧配置技术的通信***中,所述需要进行下行接收的UE将自己检测得到的检测结果在上报资源中上报给覆盖自己的基站,然后由各个基站将接收到的上报结果上报给控制节点,或者,可以将上报的检测结果 统一汇聚到其中的一个基站。例如,在图1B中,UE22或UE24可以将检测结果上报给基站12,所述基站12也可以进一步将检测结果上报给控制节点30。
所述需要进行下行接收的UE上报的内容可以是上述603部分中提及的绝对量化值,也可以是相对量化值,或者也可以是代表信号强度指示的“0”或“1”。例如,所述上报的检测结果可以是根据检测测量结果获得的位图(bitmap)信息,该位图中的0或1反映了其它UE对本UE的干扰情况,即其它UE对本UE的干扰影响是否超过门限,或者,是否小于或等于预设门限。例如,可以根据上述603部分中描述的检测结果确定方式确定该位图信息中的比特的取值。所述位图信息占用上报资源的频域的最小粒度可以是一个子载波。例如,UE可以在一个上报资源携带8比特(bit)的位图信息,若该UE检测的其它UE发送的探测信号的个数小于等于8,那么该UE只需要用长度为8比特的位图信息,且占据一个上报资源进行上报;若UE检测的其它UE发送的探测信号的个数大于8,即需要上报的总比特数大于8比特时,该UE需要将表示检测结果的总比特数分割为多个8比特的位图信息,且占据多个上报资源进行上报。当然,UE上报的内容也可以是量化测量值,本发明实施例不对此做具体限定。
若UE被配置使用如图5所示配置的上报资源,则两个被配置到相同频域位置的UE,可以使用不同的ZC序列进行码域区分,从而可以实现对两个UE上报结果的区分。
对于发射节点和接收节点分别为需要进行下行发射的基站和需要进行上行接收到基站的情况,所述需要进行上行接收的基站对所述需要进行下行发射的基站发射的探测信号进行检测得到的检测结果,也可以上报给所述控制节点。上报的内容可以是上述603部分描述的检测结果。若所述两个基站和控制节点采用无线回程的传输方式,则所述需要进行下行发射的基站可以采用配置的上报资源将所述检测结果上报给所述控制节点。若所述两个基站和所述控制节点采用有线的方式连接,则可以直接将所述检测结果上报给所述控制节点。或者,所述需要进行上行接收的基站也可以不将所述检测结果上报给所述控制节点,而是在本地保存,或者也可以将所述检测结果发送给所述需要进行下行发射的基站。
在图1B中,若按照图3所示的方式对需要进行上行接收的基站、需要进行下行发射的基站,以及需要进行下行接收的UE和需要进行上行发射的UE都配置了资源,则所述需要进行上行接收的基站对需要进行下行发射的基站发送的探测信号的检测,和所述下行接收的UE对需要进行上行发射的UE发送的探测信号的检测可以根据配置的资源一并进行,并进行上报。
根据本实施例601至604部分所描述的干扰检测方法,能够使网络设备获得需要进行上 行发射的UE和需要进行下行接收的UE之间的干扰状况,或者需要进行下行发射的基站和需要进行上行接收的基站之间的干扰状况,为***中的资源调度或干扰协调提供可靠的参考。
本发明实施例提供的技术方案还可以进一步提供干扰协调的方法,除前述601至604部分之外,还可以进一步包括:
605部分:网络设备根据所述接收节点上报的检测结果进行协调。
对于所述发射节点和接收节点分别为需要进行上行发射的UE和需要进行下行接收的UE,所述网络设备为基站的情况,可以由基站根据接收节点上报的检测结果进行协调,譬如,可以由服务所述需要进行下行接收的UE的基站调度需要进行下行接收的UE进行下行数据传输、或者不进行下行数据传输,或者,也可以由服务所述需要进行上行接收的UE的基站调度所述需要进行上行发射的UE进行上行数据传输,或者不进行上行数据传输。这样,可以避免需要进行上行发射的UE对需要进行下行接收的UE的干扰。
基站可以根据上报的检测结果,确定所述需要进行下行接收的UE受所述需要进行上行发射的UE的干扰情况,譬如,若检测结果以位图信息的形式进行上报,则可以根据位图信息获知所述需要进行下行接收的UE对接收到的所述需要进行上行发射的UE发送的探测信号的强或弱的结果,根据该强或弱的结果,可以获得所述需要进行下行接收的UE受到所述需要进行上行发射的UE的干扰是否小于或等于预设门限,即该干扰是否是可接受的程度。或者根据检测结果中相对量化值或绝对量化值确定所述需要进行下行接收的UE收到所述需要进行上行发射的UE的干扰是否小于或等于预设门限。若所述需要进行下行接收的UE收到所述需要进行上行发射的UE的干扰是可接收的程度,则调度该需要进行下行接收的UE进行下行数据传输,同时也可以调度所述需要进行上行发射的UE进行上行数据传输。若所述需要进行下行接收的UE收到所述需要进行上行发射的UE的干扰是不可接收的程度,则不调度该需要进行下行接收的UE进行下行数据传输而调度所述需要进行上行发射的UE进行上行数据传输,或者,可以不调度所述需要进行上行发射的UE进行上行数据传输而调度所述要进行下行接收的UE进行下行数据传输。
可选的,也可以由控制节点根据上述获得接收节点上报的检测结果进行协调。例如,在图1A中,可以由基站10进行调度,或者若所述检测结果都上报给控制节点30,也可以由所述控制节点进行协调。在图1B中,可以由基站12进行协调,或者若所述检测结果都上报给控制节点30,也可以由所述控制节点进行协调。
对于应用灵活TDD上下行子帧配置技术的通信***中,所述发射节点和接收节点可以 分别为需要进行下行发射的基站和需要进行上行接收的基站,所述网络设备为控制节点的情况,控制节点可以根据所述需要进行上行接收的基站上报的检测结果进行干扰协调。若所述需要进行上行接收的基站没有将检测结果上报给控制节点,则所述需要进行上行接收的基站也可以自己进行干扰协调。所述控制节点或所述需要进行上行接收的基站若根据所述检测结果确定所述需要进行上行接收的基站受到所述需要进行下行发射的基站的干扰情况小于预设门限,即处于可接受的干扰水平,则可以控制所述需要进行上行接收的基站调度上行数据接收,控制所述需要进行下行发射的基站调度下行数据发射。若确定所述需要进行上行接收的基站受到所述需要进行下行发射的基站的干扰情况大于预设门限,即不处于可接受的干扰水平,则所述控制节点可以将这两个基站的TDD上下行子帧配置设置为相同。所述预设门限或者干扰水平可以根据上下行业务的服务质量(quality of service,QoS)确定。
对于所述发射节点为需要进行下行发射的基站、所述接收节点为需要进行上行接收的基站的情况,若所述需要进行上行接收的基站没有将所述检测结果上报给控制节点,则所述需要进行上行接收的基站或所述需要进行下行发射的基站也可以进行干扰协调。所述需要进行上行接收的基站可以根据所述检测结果自己进行干扰协调,若根据所述检测结果确定所述需要进行上行接收的基站受到所述需要进行下行发射的基站的干扰情况小于预设门限,即处于可接受的干扰水平,则可以调度上行数据接收。若确定所述需要进行上行接收的基站受到所述需要进行下行发射的基站的干扰情况大于预设门限,即不处于可接受的干扰水平,则可以不调度上行数据传输,或者,可以将该需要进行上行接收的基站的TDD上下行子帧配置设置为与所述需要进行下行发射的基站的TDD上下行子帧配置相同。若所述需要进行上行接收的基站将所述检测结果发送给所述需要下行发射的基站,则所述需要下行发射的基站可以根据所述检测结果进行干扰协调,若根据所述检测结果确定所述需要进行上行接收的基站受到所述需要进行下行发射的基站的干扰情况小于预设门限,即处于可接受的干扰水平,所述需要进行下行发射的基站可以调度下行数据发射,若确定所述需要进行上行接收的基站受到所述需要进行下行发射的基站的干扰情况大于预设门限,即不处于可接受的干扰水平,则可以不调度下行数据传输,或者,可以将该需要进行下行发射的基站的TDD上下行子帧配置设置为与所述需要进行上行接收的基站的TDD上下行子帧配置相同。
通过本发明实施例提供的探测方法,可以让需要进行下行接收的UE获得其他需要进行上行发射的UE对自身的干扰影响,而通过本发明的上报方法,可以将上述需要进行下行接 收的UE探测到的其他需要进行上行发射的UE对其的干扰影响结果上报给网络设备。结合以上两方面,通过本发明实施例可以向网络设备提供应用同频全双工技术或者灵活TDD上下行子帧配置技术的通信***中干扰协调决策的必要输入,进而实现网络侧辅助的同频全双工场景下或者灵活TDD上下行子帧配置场景中的UE之间的干扰协调,从而降低同频全双工中或者灵活TDD上下行子帧配置场景UE发射对其他UE接收的干扰影响,提高同频全双工下或者灵活TDD上下行子帧配置场景的***资源利用率并增加***容量。通过本发明实施例提供的方法,也可以让相邻的配置了不同TDD上下行子帧配置的基站之间获得干扰情况,降低需要进行下行发射的基站对其它需要进行上行接收的基站的干扰影响,提高通信***中的资源利用率并增加***容量,还能够提升小区中用户的速率。
