Description

管理装置、测量装置、管理方法、测量方法和电子设备 技术领域
本公开涉及无线通信技术领域，更具体地，涉及用于实现小小区场景下对参考信号的无线资源管理测量的管理装置、测量装置、管理方法、测量方法和电子设备。
背景技术
小小区网络(SCN)被认为是应对数据流量迅速增长的有效手段。由于小小区的密集部署，小区间的同步信号和参考信号将受到严重的干扰。因此，需要解决在小小区场景下对参考信号的无线资源管理(RRM)测量。此外，为了应对将来数据流量井喷式的增长，运营商可以部署更多的小小区，尽量利用所有可利用的频谱资源。5GHz频段等一些未授权频段有着丰富的频谱资源，有效地利用该频段，可以帮助运营商提供更快、更优质的服务。然而，长期演进-未授权频带(LTE-U)或者说授权辅助接入(LAA)频带的引入使得小小区间的干扰进一步增加，从而进一步加剧了参考信号的RRM测量问题。
另一方面，目前RAN1正在进行关于小小区的开/关机制的讨论。并且RAN1设计了一个新的参考信号，即发现参考信号(DRS)来支持小小区的开/关过程。基于DRS的测量为后续小区的开/关和用户切换带来便利。但是由于DRS具有新的特点，必定不同于基于其它参考信号的RRM测量。因此，需要对基于DRS的RRM测量进行相应的修正和改进。

在此，还需要说明的一点是，为了避免因不必要的细节而模糊了本公开，在附图中仅仅示出了与根据本公开的方案密切相关的设备结构和/或处理步骤，而省略了与本公开关系不大的其它细节。
接下来，将参照图1至图18详细描述本公开的优选实施例。
首先，将参照图1描述根据本公开的实施例的无线通信系统中的用户设备侧的管理装置的功能配置示例。图1是示出根据本公开的实施例的无线通信系统中的用户设备侧的管理装置的功能配置示例的框图。
如图1所示，根据本实施例的管理装置100包括测量单元102、干扰判定单元104、滤波单元106和移动性管理单元108。接下来将详细描述各个单元的功能配置示例。
测量单元102被配置成对目标小区上的参考信号进行无线资源管理测量。优选地，目标小区是小小区，并且该小小区支持在长期演进-未授权频带上工作，例如该小小区利用LAA(Licensed-Assisted Access)技术在5GHz频段(WiFi频段)上工作。
优选地，这里的参考信号也就是包含导频序列的信号，例如可包括发现参考信号(DRS)、小区特定参考信号(CRS)和信道状态指示-参考信号(CSI-RS)中至少之一。然而，应指出，虽然这里仅列出了现有的一些参考信号的示例，但是本公开的实施例同样适用于未来随着无线通信技术的发展而提出的新的参考信号。
发现参考信号DRS是RAN1针对小小区场景而提出的一种新的参考信号，DRS的提出有助于密集小小区间的负载均衡、干扰协调、RRM测量以及小区识别等，并且DRS可包括CRS和同步信号(主同步信号(PSS)和辅同步信号(SSS))，并且在一些情况下还可包括CSI-RS。DRS相比于传统的诸如CRS、CSI-RS等的参考信号具有新的特点，因此小小区场景下对参考信号的RRM测量需要对传统的测量方式进行修改。
应指出，在以下本公开的实施例的描述中，将以DRS作为参考信号的示例进行描述，但是本公开不限于此，而是也可以类似地应用于现有其它参考信号以及未来可能出现的新参考信号。
具体地，测量单元102可进一步被配置成通过将参考信号的测量时刻与目标小区发送参考信号的发送时刻对齐来测量参考信号。此外，优选地，测量单元102可以以松弛测量方式(relaxed measurement)来测量参考信号。
传统的诸如CRS等的参考信号在每一个子帧中都出现，属于“常通(always-on)”的信号。相比较而言，DRS的周期就要长得多(可能的取值为40/80/160ms)。同时，出于干扰协调的原因，不同小小区的DRS彼此之间可能还有偏移。
此外，为了达到小小区间负载转移的目的，对异频部署的小小区间的识别，如果按照DRS的测量间隙的周期(40ms或者80ms)，将会对UE的电池产生较大的功率消耗。因此为了保证小小区的识别效果，又能尽量减少UE电量消耗，在RAN2异构网络移动性(HetNet Mobility)中，曾提出过多种小小区发现方案，其中有一种方案为松弛测量。该方案定义了更长的测量周期，以发现异频小区。松弛测量可基于突发间隙来执行，其原理如图2所示。图2是用于描述松弛测量方式的原理的示意图。
如图2所示，突发间隙每隔Tburst发生一次。每次突发事件中有Ngap个测量间隙。每个测量间隙的持续时间为Tgap，测量间隙间的间隙为MGRP。
可以看出，该测量方案省略了一些用于扫描的间隙(例如图2中的灰色间隙)，使得用户设备的电量消耗达到最小。然而，由于在很长的测量周期中，松弛测量方式仅用很小的一部分时间进行异频小区搜索，本发明人认为其测量时刻很可能与DRS的发送时刻不匹配，从而导致无法对DRS进行高效的RRM测量。
应指出，在松弛测量方式中，基站仍按照传统方式对用户设备进行测量配置，例如包含密集的测量间隙，但是用户设备可以基于基站配置的测量间隙的子集而执行连续的、较不频繁的频间小小区测量以检测小小区。
基于上述情况，针对松弛测量方式的特点，本发明设计了对DRS进行RRM测量的如下方式以高效率地实现松弛测量：其中，测量单元102可通过将松弛测量方式的突发间隙(Tburst)中的每个测量间隙的持续时间 (Tgap)与目标小区发送参考信号的发送时刻对齐，此外，将松弛测量方式的测量间隙间的间隔时间(MGRP)配置为参考信号的测量周期的(40/80/160ms)整数倍，并且将松弛测量方式的突发间隙配置为测量间隙间的间隔时间的整数倍，测量参考信号。
根据以上描述，测量单元102通过将测量时刻与参考信号的发送时刻对齐，实现了以松弛测量方式对参考信号的测量，从而降低了用户设备的能耗，并且可以获得较准确可靠的测量结果。
返回参照图1，干扰判定单元104可被配置成判定测量单元102的测量结果中的干扰是否满足预定条件，并且将其干扰满足预定条件的测量结果标记为高干扰测量结果。
在小小区场景中，由于小小区的密集部署以及小小区频繁的开/关操作，从而会产生较大的干扰。此外，针对频谱资源的稀缺，引入了长期演进-未授权频带(LTE-U)以缓解频谱资源稀缺的现状。因此，测量单元102可优选地在长期演进-未授权频带上对参考信号进行测量。然而，在LTE-U场景中，由于小小区在未授权频带上工作，因此很容易受到其它设备的干扰，从而进一步污染DRS，使用户设备无法获得准确的测量结果。
针对该情况，需要考虑小小区场景中的RRM测量结果中的干扰。对于短时高干扰的测量结果来说，其参考信号强度变化不大，主要变化的是干扰信号的强度。因此，可以维护一个变量记录当前平均干扰信号的强度。如果当前的测量结果中，干扰信号的强度明显高于原平均干扰信号强度，那么就可以认为当前的测量结果是高干扰测量结果。
依据3GPP RAN2对基于DRS的参考信号接收质量(RSRQ)的规定，有如下公式：RSRQ＝(N*RSRP)/DRSSI，其中DRSSI在所有测量子帧下行部分的OFDM符号上进行测量，其表示基于DRS测量的接收信号强度指示，而RSRP则在出现DRS信号的子帧的OFDM符号上进行测量，其表示基于DRS测量的参考信号接收功率，N表示DRSSI测量带宽的资源块数量。因此，DRS测量结果的干扰部分(包括其它信号的干扰和噪声)对应于Pi＝(DRSSI-N*RSRP)，通过Pi的大小即能知道当前干扰的大小。例如，当算出的干扰部分的值大于预定干扰阈值时，即可将该测量结果判定为高干扰测量结果。
应指出，这里给出的计算干扰部分的方法仅为示例，并且本领域技术 人员可想到采用其它方式来获得测量结果中的干扰部分，本公开对此不作限制。
滤波单元106可被配置成对测量结果进行例如3GPP LTE-A标准中的层3(L3)滤波。在本发明的一个示例中，用户设备的测量单元102首先在层1(L1)按照固定的测量周期进行同频/异频测量，然后L1以一定的时间间隔报告给L3,然后L3对本次的测量结果以及之前存储的测量结果进行滤波。
应理解，不同的信道环境、速率以及测量带宽等都会对参考信号接收功率(RSRP)和RSRQ的测量结果带来影响，为保证移动性管理决策的准确性，可通过L3滤波以产生稳定的测量结果。
移动性管理单元108可被配置成基于高干扰测量结果对用户设备进行移动性管理。
图3示出了根据本公开的实施例的管理装置中的移动性管理单元的功能配置示例。
如图3所示，移动性管理单元108可包括小区重选单元1081和报告单元1082中至少之一。小区重选单元1081可用于用户设备处于空闲状态下的小区重选，并且报告单元1082可用于用户设备处于连接状态下的测量结果上报。
应理解，在移动性管理中，与测量相关的执行动作包括用户设备处于连接状态下(RRC_connected)的成员载波的添加/删除、激活/去激活、小区切换以及用户设备处于空闲状态下(RRC_idle)的小区重选。在执行小区切换时，用户设备需要将测量结果上报给基站以由基站根据测量结果指示用户设备切换到相应的小区。而在执行小区重选时，用户设备无需将测量结果上报给基站，而是根据测量结果选择相应小区。应指出，一个成员载波通常对应于一个小区，例如与其他成员载波进行载波聚合的小区，具体地，可以是宏小区或小小区。因此，在一些情况下，提及特定成员载波时，也可以理解为与之对应的特定小区。
下面将首先针对用于进行小区切换的情况进行描述。
图4是示出根据本公开的实施例的管理装置中的报告单元的功能配置示例的框图。
如图4所示，报告单元1082可包括测量报告生成单元1082-1。该测量报告生成单元1082-1可被配置成将干扰测量结果的统计信息包含于测 量报告中。
具体地，这里所述的高干扰测量结果的统计信息可包括但不限于以下至少之一：在预定时间内总计出现的高干扰测量结果的数量、连续出现的高干扰测量结果的数量以及高干扰测量结果的数值有关的统计(例如高干扰测量结果的均值、均值相对于基准值的偏移值等)。
在该情况下，用户设备无论在任何情况下均将测量结果报告给基站，同时还将高干扰测量结果的统计信息报告给基站，以由基站根据所接收的测量报告而决定无线资源管理方案，例如如何进行成员载波的添加、删除、激活、去激活以及小区切换等移动性管理，或是功率控制、信道分配、负载控制等资源调度方案。
替选地，也可由用户设备根据测量结果来评估是否将相关小区的测量结果报告给基站。接下来将参照图5详细描述该情况。
图5是示出根据本公开的实施例的管理装置中的报告单元的另一功能配置示例的框图。
如图5所示，报告单元1082可包括上报准则评估单元1082-2，该上报准则评估单元1082-2可被配置成基于高干扰测量结果而评估是否上报目标小区的经滤波的测量结果，以及/或者是否上报高干扰测量结果的统计信息。
具体地，在一个示例中，基站在对用户设备进行测量配置时，可在配置信令中包含对测量结果上报的准则有关的信息。例如，如果对于特定小区(例如邻居小区)，与高干扰测量结果相关的信息满足预定条件(诸如高干扰测量结果大于预定阈值、连续出现预定数量的高干扰测量结果、预定时间内出现的高干扰测量结果大于预定阈值等)，则用户设备可不上报关于该小区的测量报告，或者在测量报告中需包含高干扰测量结果的统计信息。因而，上报准则评估单元1082-2可根据来自基站的测量配置，基于所接收的高干扰测量结果而评估是否符合上报准则，即，是否需要上报目标小区的测量结果或者是否需要上报高干扰测量结果的统计信息。相应地，基站生成的测量配置信息可包含关于高干扰测量结果的上报准则以便用户设备评估是否上报相应的信息。此时，报告单元1082可根据上报准则评估单元1082-2的评估结果而选择性地将目标小区的经滤波的测量结果和高干扰测量结果的统计信息包含于测量报告中以便上报给基站。可以看出，通过上报准则评估单元1082-2的处理，用户设备可以自主地决定 是否上报某些小区的测量报告。例如，对于其高干扰测量结果满足预定条件的目标小区(例如不适于作为切换目标小区)，可不上报其测量结果，这样可以减少用户设备与基站之间的信令交互，节省了资源，提高了效率。
在又一个示例中，用户设备与基站之间进行载波聚合通信，其中用户设备通过授权频段上的主成员载波PCC(对应于主小区Pcell)以及非授权频段上的辅成员载波SCC(对应于辅小区Scell)与基站通信。其中，用户设备对SCC进行RRM测量，以用于确定资源管理策略，例如是否需要去激活该SCC或者将该SCC替换为其它成员载波。在现有技术中，在用户设备对SCC的经L3滤波的RRM测量结果例如RSRP小于预定阈值，或者小于其它候选成员载波的RSRP的情况下，SCC将触发相应的报告事件，以便基站基于测量报告确定去激活该SCC或者将该SCC替换为其它成员载波。而如以上所述的，在非授权频段上的SCC所承载的参考信号可能会受到例如wifi信号暂时的高干扰，而且在本例中的非授权频段的成员载波仅作为SCC，其上的短时干扰并不会实质影响用户设备的通信，若根据现有技术的L3滤波及测量报告方式，由于滤波器的延时效应，短时的高干扰会对滤波结果造成相当长的一段时间的影响，例如L3滤波单元持续输出较低的测量结果，而可能触发预定报告事件，例如LTE-A中的事件A2(服务小区质量低于阈值)/A6(同频邻区质量高于辅小区质量)，而浪费信令资源，甚至导致基站不恰当地或频繁地去激活/替换相应的SCC。
在本发明的技术方案中，上报准则评估单元1082-2可被配置成基于高干扰测量结果而评估是否上报目标SCC的经滤波的测量结果，以及/或者是否上报目标SCC的高干扰测量结果的统计信息以供基站判断。例如，即使L3滤波输出符合传统事件上报条件，上报准则评估单元1082-2仍需评估目标SCC上的高干扰测量结果(例如输入至L3滤波的测量结果中包含的高干扰测量结果)例如是短时高干扰或是持续高干扰，从而再行决定是否上报测量结果，具体地，在上报准则评估单元1082-2根据高干扰测量结果的统计信息确定目标SCC上的干扰为短时高干扰的情况下，中止相应的事件上报，在确定目标SCC上的干扰为持续高干扰的情况下，进行相应的测量结果上报。根据上述的方案，可以提高非授权频段的可用性，节省信令开销。
此外，在一个优选的示例中，在对测量结果进行L3滤波之前，可对测量结果中的高干扰测量结果进行校正，以削除干扰对移动性管理的影 响。以下将结合图6对该优选示例进行详细描述。
图6是示出根据本公开的实施例的无线通信系统中的用户设备侧的管理装置的另一功能配置示例的框图。
如图6所示，根据本实施例的管理装置600可包括测量单元602、干扰判定单元604、干扰校正单元606、滤波单元608和移动性管理单元610。其中，测量单元602、干扰判定单元604、滤波单元608和移动性管理单元610的功能配置示例与以上描述的测量单元102、干扰判定单元104、滤波单元106和移动性管理单元108的功能配置示例相同，在此不再重复进行描述。以下将仅详细描述干扰校正单元606的功能配置示例。
干扰校正单元606可被配置成对高干扰测量结果进行校正以削除其包含的干扰对移动性管理的影响，并且将校正后的测量结果输出到滤波单元608。
优选地，干扰校正单元606可被配置成分别针对每个高干扰测量结果进行校正或者针对预定数量的测量结果中的所有高干扰测量结果集中进行校正。
具体地，针对每个高干扰测量结果进行校正至少包括以下方式之一：忽略该高干扰测量结果，从而不将该高干扰测量结果输入到滤波单元608；以上一个非高干扰测量结果作为当前的测量结果输入到滤波单元608；以及将该高干扰测量结果减去该高干扰测量结果相对于预定干扰阈值所增加的干扰值之后输入到滤波单元608。
针对预定数量的测量结果中的所有高干扰测量结果集中进行校正时，对于其中的每个高干扰测量结果，其校正方式也可采用上述方式之一。
此外，可选地，在目标小区的高干扰测量结果满足预定条件时，例如，如果连续出现了预定数量的高干扰测量结果或者在预定的时间窗内出现了预定数量以上的高干扰测量结果，则用户设备也可不对这些高干扰测量结果进行校正，而是将该干扰状况报告给基站以由基站做出决策。
作为一个示例，连续高干扰测量结果的标识和上报取决于高干扰测量结果的校正方法。具体地，在分别针对每个高干扰测量结果进行干扰校正的情况下，用户设备需要对每个高干扰测量结果进行标识，如果连续出现例如预定数量的高干扰测量结果，或者在某个预先定义的时间窗内出现了预定数量以上的高干扰测量结果，那么连续高干扰事件将被触发，并且用户设备将该事件上报给基站。另一方面，在输入L3滤波器之前集中进行 干扰校正(即，针对预定数量的测量结果中的所有高干扰测量结果集中进行干扰校正)的情况下，用户设备需要维护一个预先定义的时间窗(对应于上述预定数量的测量结果)，如果在这个时间窗内出现了预定数量以上的高干扰测量结果，那么连续高干扰事件将被触发，并且用户设备将该事件上报给基站。
替选地，为了解决在小小区场景中的LTE-U频段上进行测量的干扰问题，也可通过增强L3滤波器的方式来减小干扰的影响。以下将参照图7详细描述该情况。
图7是示出根据本公开的实施例的无线通信系统中的用户设备侧的管理装置的另一功能配置示例的框图。
如图7所示，根据本实施例的管理装置700可包括测量单元702、干扰判定单元704、调整单元706、滤波单元708和移动性管理单元710。其中，测量单元702、干扰判定单元704、滤波单元708和移动性管理单元710的功能配置示例与以上描述的测量单元102、干扰判定单元104、滤波单元106和移动性管理单元108的功能配置示例相同，在此不再重复进行描述。以下将仅详细描述调整单元706的功能配置示例。
调整单元706可被配置成对滤波单元的相关滤波参数进行调整以减少高干扰测量结果对移动性管理的影响。
具体地，L3滤波的表达式为：Fn＝(1-a)·Fn-1+a·Mn，其中，Mn为上一个从物理层获取的测量结果。Fn是更新的滤波操作后的测量结果，Fn-1是上一个滤波操作后的测量结果,F0设置为M1，即第一次从物理层获取的测量结果，α是预先确定的滤波操作系数。即，在高干扰测量结果满足预定条件的情况下，调整单元706可对其中的参数α进行调整，以减小高干扰测量结果的影响。应理解，这种调整滤波参数的方式仅为示例而非限制，并且本领域技术人员可以想到其它方式来对L3滤波器进行增强，以解决干扰问题。
同样地，调整单元706也可被配置成分别针对每个高干扰测量结果对相关滤波参数进行调整或者针对预定数量的测量结果中的所有高干扰测量结果集中对相关滤波参数进行调整。
这里应指出，在图6的实施例中描述的连续高干扰测量结果的标识和上报的过程同样适用于该实施例，在此不再重复进行描述。
根据本公开的上述实施例，其针对小小区和LTE-U场景下的参考信 号的特点以及干扰大的情况，提出了适合于该场景下的RRM测量方式，从而能够得到可靠且准确的测量结果以用于移动性管理。
应理解，上述实施例中描述的各种配置仅为本公开的优选实施例而非限制，并且本领域技术人员可根据本公开的原理而对上述实施例进行修改。例如，本公开的实施例自然也可以应用于非LTE-U的场景下，用户设备也可采用传统测量方式或者默认的松弛测量配置来执行RRM测量等等。
以上针对移动性管理中的成员载波的激活/去激活、小区切换的情况进行了描述，而对于小区重选，对于如LTE-U频段等信道质量变化比较快速的场景，也需要考虑干扰的问题。例如，可考虑如以上描述的那样对干扰进行校正或者调整滤波器参数以削除干扰的影响。具体的处理方式与上述实施例基本上相同，在此不再重复。
在小区重选时，当发现某小区测量出现连续高干扰测量结果时，小区重选单元1082例如可以考虑将该小区的重选择优先级降低。
接下来，将参照图8描述根据本公开的实施例的无线通信系统中的用户设备侧的测量装置的功能配置示例。图8是示出本公开的实施例的无线通信系统中的用户设备侧的测量装置的功能配置示例的框图。
如图8所示，根据本实施例的测量装置800可包括主小区发现单元802、交互单元804、发送时刻确定单元806和测量单元808。接下来将详细描述各个单元的功能配置示例。
主小区发现单元802可被配置成发现宏小区内的主小区并且获得主小区发送参考信号的发送时刻，该主小区是始终与用户设备保持连接的小小区。这里的参考信号可包括发现参考信号(DRS)、小区特定参考信号(CRS)和信道状态指示-参考信号(CSI-RS)中至少之一。
由于小小区往往部署在密集小区或者热点区域，在这样的部署场景中，往往会有“常通(always on)”的小小区存在。这种小小区可以认为是一种特殊的小小区(即主小区)，例如双连接中定义的pCell，可以稳定地为用户设备提供服务。因此，本发明中的pCell是设置其它小小区参考信号发送时间的参考基准，各个小小区相对于pCell具有不同的参考信号发送时间偏移。主小区发现单元802可被配置成采用默认的针对小小区发现的松弛测量配置来发现主小区，例如根据以上关于图2的描述来进行松弛测量。在一个示例中，主小区发现单元802也可被配置成采用传统测量 方式来发现主小区，用户设备在发现主小区(确定主小区参考信号时序)后再转换到松弛测量方式发现其它小小区。由于用户设备在没有参考信息的情况下进行主小区发现，采用紧凑的传统测量方式能够提高发现效率，而在确定主小区时序(其它小区参考基准)后，可以有针对性地设置对其它小小区的松弛测量方式从而实现节能高效的小小区发现。
交互单元804可被配置成与宏小区对应的宏基站或主小区对应的基站进行交互，以得到以该主小区时序为参考基准的预定范围内(例如覆盖该主小区的宏小区内)的各个小小区参考信号测量定时配置，其中，参考信号测量定时配置包括预定范围内(例如宏小区内)的所有小小区的参考信号的测量周期以及其它小小区发送参考信号的发送时刻相对于主小区发送参考信号的发送时刻的偏移。优选地，宏小区内的所有小小区均支持开/关机制。
发送时刻确定单元806可被配置成根据主小区发送参考信号的发送时刻以及所确定的偏移，确定其它小小区发送参考信号的发送时刻。
测量单元808可被配置成针对各个小小区，以使得测量该小小区的参考信号的测量时刻与该小小区发送参考信号的发送时刻对齐的方式来测量该小小区的参考信号。优选地，测量单元808可被配置成以松弛测量方式来测量参考信号。
具体地，测量单元808可通过将松弛测量方式的突发间隙中的每个测量间隙的持续时间与发送时刻对齐，将松弛测量方式的测量间隙间的间隔时间配置为参考信号的测量周期的整数倍，并且将松弛测量方式的突发间隙配置为测量间隙间的间隔时间的整数倍，测量参考信号。
图9示出了根据本公开的实施例的基于松弛测量方式的参考信号测量定时配置的示例。
如图9所示，偏移方面，将松弛测量方式的突发间隙中的每个测量间隙的持续时间Tgap与相应测量小区发送DRS的时刻对齐；周期方面，将松弛测量方式的测量间隙间的间隔时间MGRP配置为与相应测量小区的DRS周期(40/80/160ms)相同(如图9中eNB1和eNB2)或配置为相应测量小区的DRS周期的整数倍(如图9中eNB3)；另外，将松弛测量方式的突发间隙Tburst配置为MGRP的整数倍，以保证松弛测量方式的每个突发间隙都能测量到相应小区的DRS。
根据以上描述可以看出，由于DRS不是“常通”的参考信号，因此 采用松弛测量方式能够使得用户设备以较低的功耗来对DRS进行RRM测量。然而，由于松弛测量方式的测量时间占整个周期的比例很小，因此为了保证可靠地测量到目标小区的DRS，可以通过将测量时刻与发送DRS的时刻对齐的方式来进行测量。这样，能够在降低用户设备功耗的同时保证可靠且准确的测量。
下面将参照图10描述根据本公开的实施例的无线通信系统中的基站侧的管理装置的功能配置示例。图10是示出本公开的实施例的无线通信系统中的基站侧的管理装置的功能配置示例的框图。
如图10所示，根据本实施例的管理装置1000可包括接收单元1002、信息读取单元1004和管理单元1006。接下来将详细描述各个单元的功能配置示例。
接收单元1002可被配置成接收用户设备上报的无线资源管理测量报告，该测量报告包含用户设备对目标小区的参考信号的测量结果。
信息读取单元1004可被配置成读取测量报告中包含的干扰满足预定条件的高干扰测量结果有关的信息。
如之前的实施例所述，用户设备可将高干扰测量结果的统计信息(例如，连续高干扰测量结果的数量、预定时间内出现的高干扰测量结果的数量等)包括在测量报告中以报告给基站。
管理单元1006可被配置成基于测量报告而对用户设备进行无线电资源管理，例如成员载波的添加、删除、激活、去激活以及小区切换等移动性管理以及功率控制、信道分配、负载控制等资源调度方案。具体地，管理单元1006可根据各个小区的参考信号的RRM测量结果而控制用户设备例如对相应成员载波进行去激活、切换到适当的目标小区等。
进一步地，管理单元1006可被配置成根据测量报告中包括的高干扰测量结果有关的信息对用户设备进行例如移动性管理。
例如，对于用户设备上报的特定事件，基站还基于对应事件涉及的测量结果中是否包含短时高干扰而判断移动性管理方案。具体地，例如基站接收到用户设备上报的关于非授权频段上的SCC的A2事件，管理单元1006进一步根据测量报告中包含的高干扰测量结果的统计信息确定A2事件是由短时高干扰触发的，从而判断不需要对相应SCC进行去激活，借此避免了不恰当的去激活操作。
例如，对于某些高干扰的小区，基站可不将其作为用户设备的切换目 标小区，或者基站可结合各个小区的干扰情况而选择适当的小区作为用户设备的切换目标小区。
此外，基于与高干扰测量结果有关的信息(例如，高干扰测量结果的统计信息)，基站可将其干扰状况满足预定条件(例如，连续高干扰测量结果的数量大于预定阈值等)的小区加入黑名单中，并且在此后对其它用户设备进行测量配置时可考虑该黑名单。
应指出，黑名单具有时效性，其有效时间例如可根据高干扰测量结果的判定标准来设置。例如，如果黑名单中的小区连续预定数量的测量结果均不是高干扰测量结果，则可以考虑从黑名单中移除该小区。
应理解，由于用户设备需要将关于高干扰测量结果的信息上报给基站，因此基站在对用户设备进行测量配置时需要考虑与高干扰测量结果的上报有关的配置。
以下将参照图11描述根据本公开的实施例的无线通信系统中的基站侧的管理装置的另一功能配置示例。图11是示出根据本公开的实施例的无线通信系统中的基站侧的管理装置的另一功能配置示例的框图。
如图11所示，根据本实施例的管理装置1100可包括发送单元1102、接收单元1104、信息读取单元1106和管理单元1108。其中，接收单元1104、信息读取单元1106和管理单元1108的功能配置与上述接收单元1002、信息读取单元1004和管理单元1006的功能配置相同，在此不再重复描述。下面将仅详细描述发送单元1102的功能配置示例。
发送单元1102被配置成将配置信令发送给用户设备，该配置信令包括用于用户设备对目标小区的参考信号进行无线资源管理测量的测量配置信息，并且测量配置信息中包括与高干扰测量结果的上报有关的配置信息。
优选地，与高干扰测量结果的上报有关的配置信息包括上报准则配置信息，上报准则配置信息包括与高干扰测量结果的统计信息满足预定条件的目标小区的测量结果的上报有关的配置信息。
具体地，例如，上报准则配置信息可包括：如果对于目标小区的参考信号的测量结果，连续出现了预定数量的高干扰测量结果或者在预定时间内出现的高干扰测量结果大于预定数量，则用户设备无需上报关于该目标小区的测量结果，从而基站不会将该目标小区作为用户设备的切换目标小区。替选地，上报准则配置信息还可包括：如果对于目标小区的参考信号 的测量结果，连续出现了预定数量的高干扰测量结果或者在预定时间内出现的高干扰测量结果大于预定数量，则在进行测量结果报告时用户设备需要将该高干扰测量结果的统计信息上报给基站，从而由基站根据实际情况和其它小区的测量结果来做出相应的切换决策。又例如，上报准则配置信息可包括：对于当前服务的辅小区的参考信号的测量结果，如果没有连续出现预定数量的高干扰测量结果或者在预定时间内出现的高干扰测量结果小于预定数量，换言之，如果确定为短时高干扰，则用户设备无需上报关于该辅小区的特定事件，从而节省信令资源。应理解，这里所述的上报准则配置信息仅为示例而非限制，并且本领域技术人员可根据需要而对上报准则进行适当的配置。
此外，优选地，与高干扰测量结果的上报有关的配置信息还可包括例如与上报格式有关的配置信息等，例如，关于高干扰测量结果的信息在测量报告中的位置、表示方式等信息。
这样，用户设备可以根据基站的测量配置信息而返回相应的测量报告。
应理解，尽管以上描述了根据本公开的实施例的无线通信系统中用户设备侧的管理装置和测量装置以及基站侧的管理装置的功能配置示例，但是应理解，这仅是示例而非限制，并且本领域技术人员可根据本公开的原理对以上实施例进行修改，例如可对各个实施例中的功能模块进行添加、删除和/或组合等，并且这样的修改均落入本公开的范围内。
与根据本公开的实施例的装置相对应地，本公开还提供了无线通信系统中的方法。以下将参照图12至图14描述根据本公开的实施例的无线通信系统中的方法的过程示例。
首先将参照图12描述根据本公开的实施例的无线通信系统中的用户设备侧的管理方法的处理过程示例。图12是示出根据本公开的实施例的无线通信系统中的用户设备侧的管理方法的处理过程示例的流程图。
如图12所示，根据本实施例的用户设备侧的管理方法可包括测量步骤S1200、干扰判定步骤S1202、滤波步骤S1204和移动性管理步骤S1206。下面将描述各个步骤中的处理示例。
在测量步骤S1202中，可对目标小区的参考信号进行无线资源管理测量。优选地，这里的目标小区可以是小小区，并且支持在LTE-U频段上工作。此外，优选地，这里的参考信号也就是包含导频序列的信号，例如 可包括DRS、CRS、CSI-RS中的至少一个。此外，参考信号还可包括未来可能出现的其它参考信号。
优选地，在测量步骤S1202中，可以通过使得测量时刻与目标小区发送参考信号的时刻对齐的方式、在LTE-U频段上对参考信号进行RRM测量。进一步优选地，可以以所谓的松弛测量方式来测量参考信号。
在干扰判定步骤S1204中，可判定测量结果中的干扰是否满足预定条件，并且将其干扰满足预定条件的测量结果标记为高干扰测量结果。
接下来，在滤波步骤S1206中，可对测量结果进行层3滤波。
然后，在移动性管理步骤S1208中，可基于高干扰测量结果对用户设备进行移动性管理。
这里的移动性管理可包括在用户设备处于连接状态下的成员载波的添加/删除、激活/去激活、小区切换和用户设备处于空闲状态下的小区重选。其中，在执行小区切换的情况下，需要将包括测量结果的测量报告上报给基站，而在执行小区重选的情况下，无需进行上报，由用户设备根据测量结果而选择合适的小区。
优选地，为了削除干扰对移动性管理的影响，可对高干扰测量结果进行校正或者对层3滤波器的相关滤波参数进行调整。
根据上述本公开的实施例，可以实现在小小区场景下对参考信号准确且可靠的测量，同时还能够使得用户设备以较低的功耗执行测量。
接下来，将参照图13描述根据本公开的实施例的无线通信系统中的用户设备侧的测量方法的处理过程示例。图13是示出根据本公开的实施例的无线通信系统中的用户设备侧的测量方法的处理过程示例的流程图。
如图13所示，根据本实施例的用户设备侧的测量方法可包括主小区发现步骤S1302、交互步骤S1304、发送时刻确定步骤S1306和测量步骤S1308。接下来将详细描述各个步骤中的处理。
在主小区发现步骤S1302中，可发现宏小区内的主小区并且获得主小区发送参考信号的发送时刻，其中，主小区是始终与所述用户设备保持连接的小小区。优选地，可通过采用默认的松弛测量配置或者传统测量方式来发现主小区，并且宏小区内的所有小小区均支持开/关机制。此外，优选地，参考信号可包括DRS、CRS和CSI-RS中至少之一，并且还可包括未来可能出现的任何其它参考信号。
接下来，在交互步骤S1304中，可与宏小区对应的宏基站或主小区对应的基站进行交互，以得到以该主小区时序为基准的预定范围内(例如，覆盖该主小区的宏小区内)的各个小小区的参考信号测量定时配置。参考信号测量定时配置包括预定范围内(例如，宏小区内)的所有小小区的参考信号的测量周期以及其它小小区发送参考信号的发送时刻相对于主小区发送参考信号的发送时刻的偏移。
然后，在发送时刻确定步骤S1306中，可根据主小区发送参考信号的发送时刻以及偏移，确定其它小小区发送参考信号的发送时刻。
接下来，在测量步骤S1308中，可针对各个小小区，以使得测量该小小区的参考信号的测量时刻与该小小区发送参考信号的发送时刻对齐的方式来测量该小小区的参考信号。优选地，可以以所谓的松弛测量方式来测量参考信号，以降低用户设备的功耗。
根据本公开的实施例，针对小小区场景下的参考信号(例如，发现参考信号)的特点，以使得测量时刻与发送时刻的方式进行测量保证了在测量周期内能够可靠地测量到参考信号，并且还可以通过松弛测量方式来降低用户设备的功耗。
下面将参照图14描述根据本公开的实施例的无线通信系统中的基站侧的管理方法的处理过程示例。图14是示出根据本公开的实施例的无线通信系统中的基站侧的管理方法的处理过程示例的流程图。
如图14所示，根据本实施例的基站侧的管理方法可包括接收步骤S1402、信息读取步骤S1404和管理步骤S1406。接下来将详细描述各个步骤中的处理。
在接收步骤S1402中，可接收用户设备上报的无线资源管理测量报告，该测量报告包含用户设备对目标小区的参考信号的测量结果。
接下来，在信息读取步骤S1404中，可读取测量报告中包含的干扰满足预定条件的高干扰测量结果有关的信息。
然后，在管理步骤S1406中，可基于测量报告对用户设备进行无线电资源管理，例如成员载波的添加、删除、激活、去激活以及小区切换等移动性管理以及功率控制、信道分配、负载控制等资源调度方案。优选地，可基于测量报告中包括的高干扰测量结果有关的信息对用户设备进行例如移动性管理。
应理解，优选地，由于用户设备向基站报告了关于高干扰测量结果有 关的信息(例如，高干扰测量结果的统计信息等)，因此基站对用户设备做出的测量配置中必然包含与高干扰测量结果的上报有关的配置信息，并且用户设备根据该配置信息而返回相应的测量报告。优选地，该配置信息可包括与高干扰测量结果的统计信息满足预定条件的小区的测量结果的上报有关的上报准则配置信息以及相应的上报格式配置信息等等。
应指出，尽管以上描述了根据本公开的实施例的无线通信系统中的方法的过程示例，但是这仅是示例而非限制，并且本领域技术人员可根据本公开的原理对以上实施例进行修改，例如可对各个实施例中的步骤进行添加、删除或者组合等，并且这样的修改均落入本公开的范围内。

[关于基站的应用示例]
