Description

一种异构网络中小区测量方法及用户设备、基站 技术领域
本申请涉及通信技术领域,尤其涉及一种异构网络中小区测量方法及用户设备、基站。
背景技术
异构网络是一种显著提升系统吞吐量和网络整体效率的技术,是指低功率节点被布放在宏基站覆盖区域内,形成同覆盖的不同节点类型的异构系统。低功率节点(英文:Low Power Node,简称:LPN)包括微基站,毫微蜂窝基站(通常指家庭基站)等。也就是说,一个区域中可能同时有宏(macro)小区、小(pico)小区、家庭基站(femto)小区等不同大小、不同功率的无线覆盖范围。这些小区各自功率不同,在不同的位置对UE产生的干扰也不同。
在异构网络部署中,时域上采用增强的小区间干扰协调(eICIC)来提升系统和小区边缘吞吐量。在采用eICIC时,宏小区使用几乎空白子帧(英文:almost blank subframe,简称:ABS)来保护受到强小区干扰的资源,ABS子帧是指在一些物理信道中减少发送功率或者不发送。
在eICIC机制中也定义了测量资源限制的使用,如果用户设备(英文:User Equipment,简称:UE)被配置了针对摸个小区的测量资源限制,那么UE仅在对该小区配置的测量资源限制所指示的子帧中对该小区进行测量。针对一个在宏小区中的UE(简称宏小区UE),测量资源限制由宏小区配置给UE,用于UE测量受干扰的小小区。但是超密集网络中,对于小小区中UE的干扰不仅仅来自于宏小区,也来自邻小小区,则需要在各个小小区之间进行分布式协调,但是在协调后,会造成宏小区对应的宏基站无法知道受干扰的小小区的测量资源限制,从而宏小区中的UE就无法从宏小区获得受干扰的小小区的测量资源限制。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请作进一步地详细描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。
本申请提供了一种异构网络中小区测量方法及用户设备、基站,用于解决现有技术存在的宏小区UE就无法从宏小区获得受干扰的小小区的测量资源限制的问题。其中,方法和设备是基于同一发明构思的,由于方法及设备解决问题的原理相似,因此设备与方法的实施可以相互参见,重复之处不再赘述。
本申请所涉及的“多个”是指两个或者两个以上。
本申请可以应用于超密集网络(英文:Ultra Dense Network,简称:UDN),由于UDN场景中,小小区部署相对密集,业务负载相对很高,干扰动态变化。比如图1所示的UDN系统,包括宏小区(macro cell)、小小区1(Pico cell1)、小小区2(Pico cell2)、小小区3(Pico cell3)以及小小区4(Pico cell4)以及宏小区UE(MUE)。由于小小区之间有更多的重叠覆盖区域,因此小小区之 间干扰更加严重。基于此UDN场景中会存在多个受干扰小小区。另外,小小区可以被部署在多个频率上,在每个频率上都存在干扰,因此本申请提供一种异构网络中小区测量方案,来确保宏小区UE可以获取到受干扰小小区的测量资源限制,并使用测量资源限制对每个受干扰小小区进行精确的测量得到测量结果(英文:Measurement Resource Restriction,简称:MRR),以便于使用测量结果进行无线资源管理(英文:Radio Resource Management,简称:RRM)相关问题的处理。
应理解,在本发明实施例中,用户设备可称之为终端(Terminal)、移动台(英文:Mobile Station,简称:MS)或移动终端(Mobile Terminal)等。该用户设备可以经无线接入网(英文:Radio Access Network,简称:RAN)与一个或多个核心网进行通信,例如,用户设备可以是移动电话(或称为“蜂窝”电话)或具有移动终端的计算机等,例如,用户设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语音和/或数据。本申请提供了一种异构网络中小区测量方法,如图2所示,该方法包括:
S201,宏小区UE确定待测量的多个受干扰小小区的小区指示信息,以及确定用于获取所述多个受干扰小小区的测量资源限制的小小区基站。
其中,所述小区指示信息用于标识所述多个受干扰小小区。
本申请可以应用于单载波的场景中,还可以应用于多载波的场景中。当应用于单载波的场景时,多个受干扰小区同频,小区指示信息可以包括多个受干扰小小区所在的载波频率,或者包括多个受干扰小小区中每个受干扰小小区的物理小区标识(英文:Physical Cell Identity,简称:PCI)。当应用于多载波的场景时且多个受干扰小小区异频,小区指示信息可以包括多个受干扰小小区所在的多个载波频率,或者包括多个受干扰小小区中每个受干扰小区的PCI,以及每个受干扰小小区所在的载波频率。
S202,所述宏小区UE将所述多个受干扰小小区的小区指示信息发送给所述小小区基站。
S203,所述宏小区UE接收所述小小区基站发送的所述多个受干扰小小区的测量资源限制,并使用接收到的所述多个受干扰小小区的测量资源限制对所述多个受干扰小小区进行测量。
其中,所述测量资源限制是所述小小区基站基于接收到的所述受干扰小小区的指示信息确定后发送给所述宏小区UE的。
本申请中宏小区中的UE不再从宏小区获得受干扰小小区的测量资源限制,而是将待测量的多个受干扰小小区的小区指示信息发送给预先确定的用于获取所述多个受干扰小小区的测量资源限制的小小区基站,然后所述宏小区UE接收所述小小区基站发送的所述多个受干扰小小区的测量资源限制,并使用接收到的所述多个受干扰小小区的测量资源限制对所述多个受干扰小小区进行测量。由于预先确定小小区基站能够知道各个受干扰小小区的测量资源限制,因此通过该小小区基站获取到待测量的受干扰小小区的测量资源限制。
下面结合具体应用场景对本申请中描述的实施例进行作进一步描述。
场景一
需要宏小区UE测量某个载波频率上的邻小小区,具体是需要该载波频率上的受干扰小小区的测量资源限制。则宏小区UE将该载波频率发送给预先确定的一个小小区基站,则该小小区基站将该载波频率对应的测量资源限制发送给所述宏小区UE。具体可以通过如下方式实现,如图3所示:

可选地,所述宏小区UE在将确定的所述载波频率发送给所述小小区基站时,可以采用预先配置的物理随机接入信道资源将所述载波频率发送给所述小小区基站。当预先配置的物理随机接入信道资源包括多个时间时,则选择最小等待时延的物理随机接入信道资源。
S304,所述宏小区UE使用所述测量资源限制对所述多个受干扰小小区进行测量。
小小区基站向宏小区UE反馈了该载波频率对应的测量资源限制,则宏小区UE使用该测量资源限制对在该载波频率下的多个受干扰小小区进行测量。
场景二
需要UE测量多个受干扰小小区,则需要获取多个受干扰小小区的测量资源限制。则所述小区指示信息可以包括所述多个受干扰小小区中每个受干扰 小小区的PCI。多个受干扰小小区可以同频也可以异频,本申请对此不作具体限定。具体流程如图4所示。
S401a,宏小区UE确定待测量的多个受干扰小小区的PCI。
本申请中多个受干扰小小区的PCI是广义上所述的PCI,不具体限定为PCI,还可以是多个受干扰小小区的PCI索引,或者PCI组等等。
可选地,宏小区UE在确定待测量的多个受干扰小小区的PCI时,可以通过如下方式实现:

配置信息可以由运行、管理和维护设备(英文:Operations Administration and Maintenance,简称:OAM)预先配置给宏小区UE。
第二种实现方式:
所述宏小区UE使用本地测量结果确定待测量的多个受干扰小小区的PCI。
其中,所述本地测量结果为所述宏小区UE对邻小小区在不使用测量资源限制的情况下进行测量得到的测量结果。

另外,小小区基站在将每个受干扰小小区的PCI对应的测量资源限制携带在随机接入响应消息中发送给宏小区UE,随机接入响应消息携带的多个受干扰小小区的测量资源限制的顺序与所述随机接入请求消息中携带所述多个 受干扰小小区的PCI的顺序相同。从而不需要在随机接入响应消息中再次携带多个受干扰小小区的PCI,减少资源开销。
S404,所述宏小区UE使用每个受干扰小小区的PCI对应的测量资源限制对所对应的受干扰小小区进行测量。
例如,待测量的受干扰小小区为4个,物理小区标识分别为PCI1,PCI2,PCI3以及PCI4。宏小区UE在随机接入请求消息中请求4个受干扰小小区的测量资源限制。宏小区UE在随机接入请求消息中携带PCI1,PCI2,PCI3以及PCI4,并发送给小小区基站。然后小小区基站会在随机接入响应消息中携带4个受干扰小小区的测量资源限制。则可以不携带4个受干扰小小区的PCI。具体随机接入响应消息的格式可以如图5所示。其中,X用于指示该随机接入响应消息中是否携带测量资源限制。TA表示跟踪区,UL grant表示上行调度授权,T C-RNTI用于标识随机接入成功。MRR1表示PCI1对应的小小区的测量资源限制,MRR2表示PCI2对应的小小区的测量资源限制,MRR3表示PCI3对应的小小区的测量资源限制,MRR4表示PCI4对应的小小区的测量资源限制。每个测量资源限制可以占40bit,与现有的ABS占用的比特数相同。
