Description

一种基于使用非授权频谱的小区 Uscell的信息获取方法及装置 技术领域
本发明涉及通信技术领域, 尤其涉及一种基于 Uscell ( Unlicensed Cell, 使用非授权频谱的小区) 的信息获取方法及装置。
背景技术
目前, 为了对无线频率进行有效地利用, 建立了频谱规划方法一频谱管 理 ( spectrum management )。 在频谱管理中, 将频谱分为两类: 授权频谱 ( licensed spectrum )和非授权频语 (unlicensed spectrum)。 其中, 授权 频谱是指频语授权给某个移动运营商或者某个移动技术使用的频谱, 这些移 动技术包括醫 TS ( Universal Mobile Telecommunications System, 通用移 动通信系统)技术或者 LTE (Long Term Evolution, 长期演进)技术; 非 4受 权频谱是指被划分给非授权的用户使用的频谱, 在这种非授权频谱上, 不同 的无线设备可以共享频谱资源, 比如, 在中国的非授权频谱包括 2.4-2.4835 GHz和 5.725— 5.850GHz等。 目前, 移动运营商使用授权频谱为用户提供通信 服务, 但是随着用户对移动宽带的需求越来越大, 移动运营商只依靠授权频 谱资源并不能满足用户的通信需求。
结合上述描述的授权频谱不能满足用户通信服务需求的现状, 移动运营 商利用非授权频谱为用户提供通信服务。 比如, 运营商在非授权频谱上部署 3GPP ( The 3rd Generation Partnership Project, 第三代合作伙伴计划) 网络, 如 LTE , 从而可以与已有的 4受权频语上的运营商 LTE网络进行协同通信。 在授权频谱上时, 随着 UE的位置移动, 基站需要为该 UE删除信号不好的服务 小区 scell, 并添加信号好的 scell, 才能使得 seel 1为 UE提供通信服务。
在进行 scell的添加或删除时, UE需要准确、及时地获取到待测小区信息, 比如待测小区的参考信号, 并根据这些待测小区信息来确定待测小区的参考 信号质量并向基站上报, 从而基站能够为该 UE删除参考信号质量不好的服务 小区, 并添加参考信号质量好的服务小区。 但是针对 Uscell, 基站并不能持 续为 UE提供 Us ce 11信息, UE也就不能及时获取到或者只能获取到粗略的 Uscell信息, 进而不能确定 Uscell的参考信号质量, 从而导致基站不能完成 对 Uscell的添加和删除, 从而 Uscell也就不能为 UE提供通信良务, 也就不能 緩解当前移动运营商不满足用户通信服务需求的现状。

第二种方式: UE接收基站发送的 Uscell 参考信号辅助信息, 并将该参 考信号测量上报信息作为检测指示信息。
第三种方式: UE接收基站发送的参考信号测量上报信息, 并将该参考信 号测量上报信息作为检测指示信息。
其中, 参考信号的测量上报信息指示 UE上报对应 Uscell参考信号的上 报周期、 上报形式等内容。 值得说明的是, 上述第一种方式用于触发对 Uscell的识别, 第二种方式 用于测量 Uscell的参考信号, 第三种方式, 用于检测指示信息用于检测对应 Uscell 的参考信号资源的情况, 并按照该参考信号的测量上报信息所规定上 报形式向基站上报。
在本实施例的一种可选实现方式中, 当检测指示信息用于指示测量 Uscell对应的参考信号时,对应 Uscell对应的参考信号至少包括一种待测参 考信号, 这一实现方式, 将在下述图 7所示的实施例中进行详细说明。
进一步的, UE在根据检测指示信息检测到待测参考信号之后, 向基站上 报测量结果。 该检测结果表示对 Uscell 的识别结果。 或者, 检测结果表示 Uscell对应参考信号的测量结果。 或者,检测结果表示与 Uscell的距离差是 否满足预设值。
其中,该预设值表示 UE是是否已经临近该 Uscell,该预设值由系统设定。 在本实施例中当 UE与 Uscell的距离差小于或等于该预设值时,表明该 Uscell 能够为 UE提供通信服务。
值得说明的是, 检测指示信息与检测结果的可以不是一对一的关系, 可 以是一对多的组合方式。 获取到的任意一种检测指示信息的形式, 其检测结 果都可以包括: 表示对 Uscell的识别结果, 或者, 检测结果表示 Uscell对 应参考信号的测量结果, 或者, 检测结果表示与 Uscell的距离差是否满足预 设值中的任意一种或几种信息。 比如, 当检测指示信息为参考信号测量上报 信息时, 此时的检测结果可以表示 UE与 Uscell的距离差是否满足预设值, 和 /或, Uscell对应参考信号的测量结果。
此外, 当检测指示信息为参考信号测量上报信息时, 且当检测结果包括 Uscell的 CQI时, 该检测结果表示 CQI所属的 Uscell或导频的标识和该 CQI 的等级。 而对于该 CQI 的具体上报形式将在下述图 Ί所示的实施例中及其对 应的实现方式中进行详细描述。
本发明另一实施例提供了一种基于 Uscell的信息获取方法, 在这一实施 例中, Uscell 在不同的基站 ENB之间, 比如 Uscel 11属于 ENB1而 Uscel 12 属于 ENB2, 并且 ENBl与 ENB2之间没有理想回程线路 backhual。 在这种情况 下,由于不同 Uscell 属于不同的 ENB,而不同的 ENB根据竟争到的资源情况, 会在不同时间发送可能的参考信号, 而基站间的协调过程中存在时延, 从而 ENB1 下的 UE 不能准确的知道 ENB2 什么时间发送参考信号。 其中, 这些参 考信号可以是 SS ( synchronization signal 是同步信道)、 CRS ( cell reference signal , 小区参考信号 )、 CSI-RS ( ChannelStatelndicat ion Reference Signal,信道状态指示参考信号)、 DMRS ( De Modulat ion Reference Signal,解调的参考信号)等。
具体的, 如图 5所示, 本实施例以 UE在 ENB1下为例, 该方法包括:
501、 ENB1为 UE配置 Uscell。
可选的, ENB1通过 RRC (Radio Resource Control, 无线资源控制协议) 消息为 UE配置 Uscell, 比如配置 Uscell所在的频率等。
502、 UE才艮据配置的 Uscell 自主检测 Uscell。
具体的, UE自主检测 Uscell包括但不限定有如下两种检测形式: 第一种: 在 ENB1为 UE配置好 Uscell之后, UE立即检测 Uscel 1;
第二种: 在 ENB1为 UE配置好 Uscell之后, UE不及时触发检测, 直到 ENB1向 UE发送检测指令, UE根据该检测指令检测 Uscell。
可选的, UE检测 Us ce 11的方式可以采用盲检方式, 从而 UE通过盲检识 别出满足该 Uscell配置的小区。
503、 UE向 ENB1上报检测结果。
具体的, 本发明实施例中, 该检测结果包括 UE识别到 Uscell, 并同时上 报识别出的是哪个或哪些 Uscell; 或者检测结果为 UE未识别出 Uscell。
当未识别出 Uscell时, 方案停止执行, 或者继续检测, 或者达到预设检 测时间或预设检测次数时, 停止检测等, 本发明实施例对此不进行限制。 在 本实施例中以该检测结果表示 UE识别到 Uscell为例进行说明。
具体的, UE 上报的检测结果可以是只指示该 UE发现了 Uscell, 也可以 进一步指示 UE 发现 Uscell的频率或带宽, 或者是 Uscell的标识,根据实际 情况, 或者该检测结果中还可以包括对该识别出来的 Uscell的参考信号的测 量结果,或者该检测结果中还可以包括 UE是否临近该 Uscell,也就是说 UE与 该 Uscell 的距离差是否满足预设值, 该检测结果中还可以包括对识别出的 Uscell对应的参考信号的测量结果。
值得说明的是, 该检测结果中还可以包括其它任意一种或几种消息, 本 发明实施例对此不进行限制。
结合上述图 5中描述的方法, 在这一实施例的一种实现方式中, 结合 501 的描述, 还可以是 ENB1向 UE发送 Uscell参考信号辅助信息。
其中, Uscell参考信号辅助信息包括但不限定为 ENB2发送 Uscell可能 参考信号的时间段或者样式 paUern。
进一步的, 是 UE根据该 Uscell参考信号辅助信息进行 Uscell参考信号 的测量。
在这一实现方式中, UE向 ENB1上报的检测结果至少表示表示 Uscell对 应参考信号的测量结果, 当然该检测结果中还可以表示 UE对 Uscell 的识别 结果, 以及 UE与 Uscell 的距离差值等。 当然根据实际情况, 该检测结果中 还可以包含其余任意一种或几种信息, 本实现方式中对检测结果中包括的具 体内容不作限定。
值得说明的是, 结合上述提到的 Uscell参考信号辅助信息中的内容, 这 里提到的 UE根据 Uscell参考信号辅助信息进行检测与盲检相比, 更明确了 检测的时间, 减少了 UE检测 Uscell的复杂度, 提高了检测效率。
本发明实施例对 UE检测 Uscell的具体方式不作限定。
本发明另一实施例提供了一种基于 Uscell的信息获取方法, 在本实施例 中, 与上一实施例中的描述的方法的应用场景相同,如图 6所示, 该方法包括:
601、 ENB1为 UE配置 Uscell。
602、 UE触发对 Uscell的测量。
值得说明的是, 在本实施例中, UE可以不依赖与 ENB1配置的 Uscell, 而触发对 Uscell的测量。 也就是说, 上述的 601 、 602步骤可以是独立的。 此外值得说明的是, 与上一实施例中, ENB1为 UE配置 Uscell相比, 本 实施例中如果不执行上述步骤 601, 则说明当前 ENB1并不希望 UE应用 Ucell 资源, 或者 ENB1不确定 UE位置, 也就不确定 UE能够使用的 Ucell, 此时, UE可以自主对周围的 Ucel 1的情况进行检测, 并及时更新检测结果, 以便将 该检测结果上报给 ENB1。
其中, Uscell与 Ucell均表示使用非 4受权频语的小区,但是其中的 Uscell 表示 ENB1为 UE配置的使用非授权频谱的小区, Ucell表示 ENB1没有为 UE配 置的使用非授权频谱小区。
603、 UE向 ENB1上报检测结果。
具体的, 在本实施例中, UE是否向 ENB1上报检测结果, 包括但不限定有 下述两种情况:
第一种情况: UE是否向 ENB1上报检测结果,取决于 ENB1是否为 UE配置 了 Uscell, 在这一情况下分为下述两种形式:
第一种形式: 当 UE发现了 Uscell且 ENB1没有为 UE配置 Uscell时, 则 此时 UE不上报该检测结果表明其检测到了 Uscell。
第二种形式: 当 ENB1为 UE配置了 Uscell时, UE才向 ENB1上>¾其检测 到的 Uscell。
第二种情况: UE还可以不依赖于 ENBl配置的 Uscell,在 UE检测到 Uscell 之后, UE再向 ENB1上报检测结果。 其中, 本实施例对 UE上报该检测结果的 时间不进行限定。
本发明另一实施例提供了一种基于 Uscell的信息获取方法, 在本实施例 中, Uscell在同一个 ENB 下, 或者 Uscel 1在不同的 ENB之间, 但是 ENB之间是 理想 backhaul。 基站间存在理想的 backhaul也就是说明, ENB 可以同步获取 不同小区发送参考信号的时间。 其中, 这些参考信号可以是 SS, CRS,或 CSI-RS,DMRS 等。 在这种情况下, ENB1可以给 UE 配置不同的参考信号测量和 上报资源来实现 UE快速的发现临近的 Ucell 并通知 ENB1。
则在本实施例中, 如图 7所示, 该方法包括: 701、 ENB1为 UE配置多套 Us ce 11的参考信号资源。
在本实施例中, 为了简便描述将该多套 Uscel l的参考信号资源描述为多 套测量资源。
其中, 多套测量资源可以分为下述三类:
第一类: 多套测量资源可以是 CRS、 CSI-RS、 SS或者 DMRS四种测量资源中 的任意两种或几种。
第二类: 该多套测量资源是四种测量资源中任意一种, 且该测量资源有 至少两种分类。
具体的, 由于这四种测量资源中的任意一种还可以进行具体划分, 比如 其中的, CRS可以包括 CRS1、 CRS2、 CRS3等, 这只是对其中的一种资源具体划 分的一种举例, 且其中的 CRS1、 CRS2、 CRS3只是对 CRS不同种类的划分, 只是 一种标识作用, 不表示 CRS具体细分种类后的名称, 本发明实施例对每一种测 量资源的分类, 以及每一种分类的表示形式不作限定。
第三类: 该多套测量资源是四种测量资源中的任意一种或几种, 或者是 任意一种测量资源的任意一种或几种分类。
值得说明的是, 根据实际情况, 该测量资源还可以是其余任意一种或几 种参考信号, 本发明实施例对此不作限定。
702、 ENB1向 UE发送参考信号测量上报信息。
其中, 该参考信号测量上报信息指示 UE上报参考信号的上报周期、 上报 形式等内容。
值得说明的是, 本实施例中步骤 701与 702的执行顺序不限定与上述的顺 次顺序关系。
703 、 UE根据 ENB1的指示获取不同的参考信号。
值得说明的是, ENB1的指示包括但不限定包括以下两种指示情况: 第一种指示情况: ENB1通过 PDCCH ( Phys ica l Downl ink Cont rol Channel , 物理下行控制信道) 或 EPDCCH ( Enhanced Phys ica l Downl ink Cont rol Channel , 增强下行物理控制信道) 指示 UE获取参考信号。 在该第一种指示情况下: ENB1可以直接是指示 UE参考信号的时频资源位 置, 此时, PDCCH或者 EPDCCH中的内容信息包括 UE获取参考信号的位置信息, 则 UE可以不需要通过 ENB1为 UE配置的多套测量资源来获取参考信号。
第二种指示情况: UE根据 ENB1为 UE配置的多套测量资源, 获取参考信号。
704、 UE根据参考信号测量上报信息向 ENB1上报检测结果。
其中 ,检测结果包括不同的测量值。
上报的测量值具体包括下述三种形式:
第一种形式: 上报的测量值可以是基于参考信号的 RSRP或 RSRQ (Reference S igna l Rece iving Qua l i ty, 参考信号接收质量)。
第二种形式: 上报参考信号的 RSRP或 RSRQ是否高于一定门限。
具体的, 该一定门限值由 ENB1或系统设定。 比如, 当高于一定门限值时, 上报值为 1 , 当低于门限值时上报值为 0。
第三种形式: 上报一个 CQI索引值, 直接指示信道的状态等级。
其中, CQI索引值用于表示信道质量的优劣。 CQI索引值高表示信道质量 好。
值得说明的是, 根据实际情况, 本发明实施例中上报的测量值的形式还 可以包括其余任意一种或几种信息, 本发明实施例对此不进行限制。
本发明实施例提供的基于 Uscel l 的信息获取方法, ENB1 配置 UE 多套 测量资源, 进而 UE根据 ENB1的指示获取不同的参考信号, 更进一步的, UE 上报测量值。 在本实施例中, UE获取不同的参考信号, 这样就使得 UE能够多 重选择获取参考信号的时间以及获取参考信号的位置, 这样 UE就能够更为准 确的获取到参考信号。
进一步的, 在本实施例的另一种实现方式中, ENB1可以给 UE 配置或 指示多个导频或小区,并指示 UE 测量参考信号,比如指示 UE测量 CSI-RS。
进一步的, 在本实施例的另一种实现方式中, UE 上报的检测结果能 够表示 UE是否临近该小区或该小区的 CQI 是否超出范围 out of range, 其中的小区指的是 Usec l l。 值得说明的是, UE 同一时刻可用少数小区, 这样 ENB1可以给 UE上 的资源共享 (比如配置 UE 10 个可以测量的导频标识), 然后 UE通过 该 UE上报的资源共享向 ENB1上报可以测量到的导频标识, 或上报对应 导频 CQI 不是 out of range 的导频标识, 或上报最好的 M个导频标识, 其中 M为小于 10的正整数。
在本实施例的一种具体的实现方式中, 当检测结果为 Uscel l 的 CQI 时, 该检测结果包含两部分内容, 分别表示 CQI所属的 Uscel l或导频的 标识, 和该 CQI的等级。
值得说明的是, 由于在本实施例提供的实现方式中, 检测结果中上报 的是信号质量好的 Uscel l,且在该上报结果的一部内容中记载的是 CQI所 属的 Uscel l或导频的标识, 则说明 UE 已经临近对该标识对应的 Uscel l 或导频,而在该上报结果的另一部分内容中记载了 CQI 的等级, 从而能够 通过该 CQI等级表示出 CQI是否超出范围。
在向 ENB1的具体上报过程中, 比如, 可以复用 CQI 上报的 5bi t , 在 该检测结果中, 对 CQI 的 5bi t这样划分: 前 4个 bi t表示 CQI是属于哪 个导频或 Uscel l的标识,后 1个 bi t是表示测量 CQI 是否 out of range。
这样的上报形式相对于现有技术中, 5bi t 全部用于上报 CQI 等级, 该等级为 32个 CQI等级中的一种。 在 UE向 ENB1上报过程中, 只是对其 CQI 等级进行上报, ENB1 并不能明确获知该 CQI 是属于哪一个导频或 Uscel l的。 并且在该实施例中, ENB1无需获取到每个 Uscel l或导频对应 的 CQI的精确等级,这样采取原有的 CQI上报形式就造成了系统资源浪费, 所以本实施例中提出的新的上报形式显著减少了系统资源的浪费。
值得说明的是, 上述只是描述了一种 CQI上报形式, 在实际应用过程 中, 本发明实施例对该具体上报形式不作限定。 比如, 还可以是 5bi t 中 的前 3个 bi t表示 CQI是属于哪个导频或 Uscel l的标识, 后 2个 bi t表 示测量的对应导频的 CQI 是否 out of range。 或者该 bi t的总位数不限 定为 5。 通过以上的实施方式的描述, 所属领域的技术人员可以清楚地了解到本 发明可借助软件加必需的通用硬件的方式来实现, 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, 本发明的技术方案本 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可读取的存储介质中, 如计算机的软盘, 硬盘或光盘 等, 包括若干指令用以使得一台计算机设备(可以是个人计算机, 服务器, 或者网络设备等)执行本发明各个实施例所述的方法。
以上所述, 仅为本发明的具体实施方式, 但本发明的保护范围并不局限 于此, 任何熟悉本技术领域的技术人员在本发明揭露的技术范围内, 可轻易 想到变化或替换, 都应涵盖在本发明的保护范围之内。 因此, 本发明的保护 范围应以所述权利要求的保护范围为准。
