Description
频潘资源的配置调整方法和装置及系统
本申请要求于 2010 年 8 月 24 日提交中国专利局、 申请号为 201010264177.4、 发明名称为 "频语资源的配置调整方法和装置及系统" 的中 国专利申请的优先权, 其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信技术领域,具体涉及频谱资源的配置调整方法和装置及系 统。
背景技术
当前, 随着使用移动通信系统的用户数的日益增多, 以及单个用户的业务 量的指数增长, 无线资源日益成为非常紧缺的资源。
解决频谱资源匮乏的问题, 可从 2个方面进行解决, 一方面, 继续寻找新 的频谱资源分配给移动通信系统使用; 另一方面, 针对较低的频谱使用率, 研 究如何能够更好的应用空闲的频谱资源。
在实际应用中,被分配出的频谱并没有得到充分的应用, 频谱的使用率并 不高。 例如在频分双工 (FDD, Frequency Division Duplexing ) 系统中, 下行 频段和上行频段通常使用相同的带宽,但是目前上下行的业务量并不均衡, 下 行的业务量通常更大, 而上行的业务量通常却大大小于下行的业务量, 这样就 会导致部分上行(UL, Up link ) 资源的相对空闲。 另一方面, 由于新的上行 占优业务以及其它可能的上行业务的不断出现, 上行的业务量也会逐渐的增 加, 比如采用单向转发器, 仅仅放大上行的信号。 或者, 在异构网络中采用上 行多点协作传输技术或范围扩展(RE, Range extension )技术, 也会使上行频 谱效率大于下行频谱效率, 这样, 即使在上行业务量和下行业务量相匹配的情 况下, 由于上行频谱效率比下行频谱效率更高,使得上行子帧的使用率可能比 下行子帧低, UL资源可能会出现一些冗余。

以下通过具体实施例分别进行详细说明。
需要说明,本发明实施例所指接入网设备是可实现终端无线接入管理的实 体, 在不同的网络中可能具有不同的名称、 位置和产品形态, 例如为: 演进通 用移动通信系统 ( UMTS , Universal Mobile Telecommunications System ) 陆地 无线接入网 (E-UTRAN, Evolved UMTS Territorial Radio Access Network ) 中 的演进基站 (eNodeB )、 家庭基站 ( HeNB )或其它类型的基站; 或, UMTS 陆地无线接入网 (UTRAN, UMTS Territorial Radio Access Network ) I GSM EDGE无线接入网 (GERAN, GSM EDGE Radio Access Network ) 中的基站控 制器、 或无线网络控制器(RNC, Radio Network Controller )等; 非 3GPP网络 中接入网设备可指: 无线局域网 (WLAN, Wireless Local Area Network ) 中具

本发明实施例的技术方案主要针对例如 FDD系统的 UL/DL频谱资源的使 用率较低的问题, 研究如何能够更好的应用空闲的 UL/DL频谱资源。 本发明实 施例中主要考虑某一接入网设备 (例如宏基站、微微 ( Pico )基站、微( Femto ) 基站或者其它类型的基站或中继站(Relay ) )将其冗余的 UL/DL频谱资源提供 给相邻的另一接入网设备(例如微基站、 微微基站、宏基站或其它类型的基站 或中继站 ), 以便该另一接入网设备增添至少一条无线链路 (包括接入链路和 / 或无线回程链路等)或扩充其至少一条无线链路(包括无线接入链路和 /或无 线回程链路等)的资源配置, 实现 UL/DL频谱资源的充分利用。 一个小区对应 有一对接入链路, 即上行接入链路和下行接入链路。无线回程链路也包括上行 无线回程链路和下行无线回程链路。
本发明实施例中主要以物理资源块( PRB , Physical Resource Block )作为 是无线帧中的时频资源的一种单位来进行描述,一个物理资源块可包括无线帧 中的一定时隙内的多个子载波组成的时频资源。 实施例一
下面以提供频谱资源的接入网设备的角度,描述本发明频谱资源的配置调 整方法的一个实施例, 可包括: 第一接入网设备向第二接入网设备发送第一消 息, 其中, 该第一消息携带第一指示信息, 该第一指示信息指示出第一接入网 设备调整的第一小区的物理资源块 PRB的调整数量;第一接入网设备接收第二 接入网设备发送的第二消息, 其中, 该第二消息携带有第二指示信息, 该第二 指示信息指示出第二接入网设备根据第一指示信息来调整的无线链路的 PRB 的调整位置。
参见图 1 , 具体步骤可以包括:
110、 第一接入网设备向第二接入网设备发送第一消息, 该第一消息携带 第一指示信息,该第一指示信息指示出第一接入网设备调整的第一小区的物理 资源块 PRB的调整数量。
在实际应用中,第一指示信息可以是能够向第二接入网设备指示出第一接 入网设备调整的第一小区的 PRB的调整数量或调整位置(指示调整位置也就指 示出了调整数量)的任意信息, 第一指示信息例如可包括如下信息的一种或多 种: 第一接入网设备所调整第一小区资源的频点信息、所调整第一小区资源的 带宽信息、所调整第一小区资源的时隙个数信息、所调整第一小区资源的时隙 位置信息、 所调整第一小区资源的时隙偏置信息。 当然, 第一指示信息也可不 包括上述信息中的其中一个或多个,而第一接入网设备和第二接入网设备之间 间可采用默认方式确认对应的配置方式。例如, 若第一指示信息中不包括第一 接入网设备所调整第一小区资源的频点信息、第一接入网设备所调整第一小区 资源的带宽信息, 此时, 第二接入网设备可默认为第一接入网设备所调整的第 一小区资源的频点为小区下行频段对应的起始频点,第一接入网设备所调整的 第一小区资源的带宽为小区下行频段对应的带宽, 以此类推。 或者, 接入网设 备间也可以协议规定一种或几种固定的资源调整方式,接入网设备之间可直接 交互资源调整的方式信息或者只交互资源调整方式对应的索引信息,即可将资 源调整情况通知对端。 当然, 如果只有一种资源调整方式, 则可只需要通知对 端是否调整资源即可。
相应的, 第二接入网设备可根据第一指示信息的指示, 获知第一接入网设 备对第一小区的 PRB的调整情况。 例如, 第二接入网设备可根据第一指示信息 指示出的第一接入网设备调整的第一小区的 PRB的调整数量,确定出调整对应 无线链路的 PRB配置的调整位置,并可按照确定出的调整位置来调整该无线链 路的 PRB配置, 并可向第一接入网设备反馈其调整的该无线链路的 PRB的调整 位置信息。或者, 第二接入网设备可根据第一指示信息指示出的第一接入网设 备调整的第一小区的 PRB的调整位置, 确定出调整对应无线链路的 PRB配置的 调整位置, 并可按照确定出的调整位置来调整该无线链路的 PRB配置, 并可向 第一接入网设备反馈其调整的该无线链路的 PRB的调整位置信息。
可选的, 当第三接入网设备为第二接入网设备的相邻的接入网设备时,根 据第二接入网设备的干扰情况,第一接入网设备还可以向第三接入网设备发送 调整 PRB数量信息,而第二接入网设备则可选的向第三接入网设备发送调整的 PRB位置信息, 第三接入网设备可据此也进行相应的调整, 以减小干扰。
在一种应用场景下,携带第一指示信息的第一消息例如可为 eNB配置更新 消息、 小区激活请求信息、 标准定义的其它消息或新增的消息。 此外, 第一消 息也还可携带如下信息的一种或多种:第一接入网设备所调整第一小区资源的 用途信息 (例如可指示用于配置小区接入链路, 和 /或, 指示用于配置无线回 程链路等, 和 /或, 指示节能配置)、 第一小区资源调整的激活时间信息、 上下 行保护间隔的配置信息等。
第一接入网设备在向第二接入网设备发送第一消息之前,还可接收第二接 入网设备的上行和 /或下行资源的使用状况指示信息; 或, 接收第二接入网设 备及第二接入网设备的相邻接入网设备的上行和 /或下行资源的使用状况指示 信息, 并据此获知第二接入网设备上行和 /或下行资源是否不足, 以及获知第 二接入网设备与其相邻接入网设备之间可能存在的干扰问题。
在一种应用场景下, 第一接入网设备向第二接入网设备发送第一消息,之 前还可接收第二接入网设备的小区配置能力信息,该小区配置能力信息可包括 发射机配置信息 (例如可包括发射机个数信息)和 /或接收机配置信息 (例如 可包括接收机个数信息)。 和 /或, 接收第二接入网设备发送的未激活小区的小 区配置信息, 该小区配置信息包括如下信息的一种或多种: 公用陆地移动通信 网 (PLMN, Public Land Mobile Network )标识、 物理层小区标识、 高层小区 标识、 小区模式信息、 小区的状态信息等。
120、 第一接入网设备接收第二接入网设备发送的第二消息, 该第二消息 携带有第二指示信息,该第二指示信息指示出第二接入网设备根据第一指示信 息来调整的至少一条无线链路的 PRB的调整位置。
在实际应用中,第二指示信息可以是能够向第一接入网设备指示出第二接 入网设备调整的无线链路的 PRB的调整位置(指示调整位置也就指示出了调整 数量)的任意信息。 第二指示信息例如包括如下信息的一种或多种: 所调整无
线链路资源的频点信息、所调整无线链路资源的带宽信息、所调整无线链路资 源的上行和 /或下行时隙位置信息、 所调整无线链路资源的时隙偏置信息。
其中, 携带第二指示信息的第二消息例如可为 eNB配置更新消息、 小区激 活响应信息、 标准定义的其它消息或新增的消息。 此外, 第二消息还携带: 所 调整无线链路资源的用途信息 (用途信息例如可以指示用于配置小区接入链 路, 和 /或, 指示用于配置无线回程链路, 和 /或, 节能配置等), 和 /或, 无线链 路资源调整的激活时间信息。
在一种应用场景下, 第一接入网设备可监测第一小区的上行 /下行 PRB的 使用率; 若根据监测到第一小区的上行 /下行 PRB的使用率确定第一小区存在 冗余的上行 /下行 PRB , 则可减少第一小区的上行 /下行 PRB的配置数量, 而该 第一指示信息可指示出第一接入网设备减少的第一小区的上行 /下行物理资源 块 PRB的配置数量; 若根据监测到第一小区的上行 PRB的使用率确定第一小区 的上行 /下行物理资源块不足, 则第一指示信息可指示出第一接入网设备将增 加的第一小区的上行 /下行物理资源块 PRB的配置数量, 并可在接收第二接入 网设备发送的第二消息后, 增加第一小区的上行 /下行 PRB的配置数量。
需要说明的是, 若第一接入网设备和第二接入网设备为基站, 则其可通过 基站间直接的接口 (如 X2、 Iur、 Iub或空口); 或通过基站间间接的接口 (比 如 SI , Iu口 ) 交互信息。
在一种应用场景下, 在第一接入网设备向第二接入网设备发送第一消息 后, 或, 在第一接入网设备接收第二接入网设备发送的第二消息后, 第一接入 网设备还可通过系统消息或者专用信令,向其服务的部分或全部用户终端发送 服务小区更新配置信息,该服务小区更新配置信息可包括如下信息的一种或多 种: 所调整第一小区资源的上行和 /或下行频点信息、 所调整第一小区资源的 上行和 /或下行带宽信息、 调整第一小区资源后的空白时隙的上行和 /或下行位 置信息、 第一小区资源调整的激活时间信息、 上下行保护间隔的配置信息。 相 应的, UE可据此获知第一小区的资源调整情况。
在一种应用场景下,在第一接入网设备接收第二接入网设备发送的第二消 息后, 第一接入网设备还可通过系统消息或专用信令, 向其服务的部分或全部
用户终端发送相邻小区配置更新信息, 该相邻小区配置更新信息可包括: 如下 信息的一种或多种: 第二接入网设备所调整相邻小区资源的频点信息、所调整 相邻小区资源的带宽信息、所调整相邻小区资源的时隙位置信息、所调整相邻 小区资源的时隙偏置信息、 相邻小区资源调整的激活时间信息。 相应的, UE 可据此获知相邻小区的资源调整情况。

在一种应用场景下,若第一接入网设备所调整的第一小区的 PRB用于第二 接入网设备配置小区的无线接入链路,则第一接入网设备调整的第一小区的上 行和 /或下行资源位置关系可以满足在第二接入网设备配置为时分双工(TDD, Time Division Duplexing ) 配置兼容的小区的无线接入链路; 或者, 第一接入 网设备调整的第一小区的上行和 /或下行资源位置关系满足在第二接入网设备 配置为非 TDD配置兼容的小区的无线接入链路。相应的,第二接入网设备可在 第一接入网设备调整的第一小区的上行和 /或下行资源位置, 对应配置 TDD配 置兼容的小区的无线接入链路; 或者,对应配置非 TDD配置兼容的小区的无线 接入链路。
在一种应用场景下,第一接入网设备还可在第一消息携带用于指示第二接 入网设备配置小区的下行无线接入链路和上行无线接入链路的保护间隔的保 护间隔配置指示, 其中, 该保护间隔配置指示可用于指示出: 在相邻的一个或 多个下行传输符号和 /或上行传输符号上不进行数据的传输, 以将该一个或多 个下行传输符号和 /或者上行传输符号作为保护间隔; 或者, 将相邻的一个或 多个下行传输符号和 /或者上行传输符号向前或向后偏移一个或多个符号, 以 将偏移空出的传输符号作为保护间隔。相应的, 第二接入网设备可据此设置保
护间隔, 当然, 第二接入网设备也可自行确定如何设置保护间隔。 在一种应用场景下,若第一接入网设备所调整的资源为第一小区的上行资 源,且该调整的上行资源用于配置第一接入网设备和第二接入网设备之间的无 线回程链路时,所配置的第一接入网设备和第二接入网设备之间的无线回程链 路的下行时隙位置在第一接入网设备和第二接入网设备上可满足 TDD配置兼 容方式中的部分或全部的下行时隙的位置、所配置的第一接入网设备和第二接 入网设备之间的无线回程链路的上行时隙位置在第一接入网设备和第二接入 网设备上满足 TDD配置兼容方式中的部分或全部的上行行时隙的位置。
第二接入网设备可在配置无线回程链路后的剩余上行时隙的位置配置为 无线接入链路的上行时隙。
在一种应用场景下,若第一接入网设备所调整的资源为第一小区的上行资 源和 /或下行频段资源, 且所调整的第一小区的上行资源和 /或下行频段资源用 于配置无线接入链路以及第一接入网设备与第二接入网设备之间的无线回程 链路时,则所配置的第一接入网设备与第二接入网设备之间的下行回程链路的 时隙位置可对应为第二接入网设备上配置的无线接入链路的部分或全部上行 时隙位置,无线接入链路的上行时隙位置满足 TDD配置兼容方式或非 TDD配置 兼容方式中的上行时隙的位置;所配置的第一接入网设备与第二接入网设备之 间的上行回程链路的时隙位置对应为第二接入网设备上配置的无线接入链路 的部分或全部下行时隙位置,无线接入链路的下行时隙位置满足 TDD配置兼容 方式或非 TDD配置兼容方式中的下行时隙的位置;第一接入网设备与第二接入 网设备之间的上行无线回程链路和第二接入网设备上的无线接入链路的部分 下行时隙以时域、 频域或资源块方式复用。
由上可见, 本实施例的方案中, 小区上行和 /或下行资源冗余的第一接入 网设备通过调整该小区的资源配置,将该小区冗余的部分或全部资源提供给与 之相邻的第二接入网设备用于配置小区无线接入链路和 /或无线回程链路, 而 第二接入网设备则根据第一接入网设备对小区的资源配置的调整,来对应的调 整其小区无线接入链路和 /或无线回程链路的资源配置, 该机制有利于提高资 源的利用效率, 提升系统性能和服务质量。
下面以接收频谱资源的接入网设备的角度,描述本发明频谱资源的配置调 整方法的一个实施例, 可包括: 第二接入网设备接收第一接入网设备发送的第 一消息, 其中, 第一消息携带第一指示信息, 第一指示信息指示出第一接入网 设备调整的第一小区的物理资源块 PRB的调整数量;根据第一指示信息指示出 的第一接入网设备调整的第一小区的物理资源块 PRB的调整数量,调整的无线 链路的 PRB的位置; 向第一接入网设备发送第二消息, 其中, 第二消息携带有 第二指示信息,第二指示信息指示出第二接入网设备根据第一指示信息来调整 的无线链路的 PRB的调整位置。
在一种应用场景下, 若调整无线链路包括小区无线接入链路, 则调整无线 链路的 PRB的位置之后, 第二接入网设备还可通过系统消息或专用信令, 向其 服务的部分或全部用户终端发送服务小区更新配置信息,该服务小区更新配置 信息如下信息的一种或多种: 所调整小区无线接入链路资源的上行和 /或下行 频点信息、 所调整小区无线接入链路资源的上行和 /或下行带宽信息、 小区无 线接入链路资源调整的激活时间信息。
在一种应用场景下, 在接收第一接入网设备发送的第一消息, 或, 向第一 接入网设备发送第二消息之后,第二接入网设备还可以通过系统消息或专用信 令, 向其服务的部分或全部用户终端发送相邻小区配置更新信息, 该相邻小区 配置更新信息如下信息的一种或多种:第一接入网设备所调整第一小区资源的 频点信息、 所调整第一小区资源的带宽信息、 所调整第一小区资源的上行和 / 或下行的时隙位置信息、所调整第一小区资源的时隙偏置信息、第一小区资源 调整的激活时间信息、 上下行保护间隔的配置信息。
在一种应用场景下, 若调整无线链路包括无线回程链路,调整无线链路的 PRB的位置之后, 第二接入网设备还可通过系统消息或专用信令, 向其服务的 部分或全部用户终端发送无线回程链路配置信息,上述无线回程链路配置更新 信息包括如下信息的一种或多种: 所调整无线回程链路资源的频点信息、所调 整无线回程链路资源的带宽信息、 所调整无线回程链路资源的上行和 /或下行 的时隙位置信息、所调整无线回程链路资源的时隙偏置信息、无线回程链路资 源调整的激活时间信息。
实施例二
为便于更好的理解, 下面以某个宏基站将其冗余的 UL频谱资源提供给某 个 Pico基站应用于其接入链路的过程为例, 对本发明实施例的技术方案进行更 为详细的描述。
参见图 2, 例如宏基站 Ml和宏基站 M2为微微(Pico )基站 PI的相邻基站, 本发明实施例中频谱资源的配置调整方法的另一个实施例, 具体可包括:
201、 宏基站 Ml和 Pico基站 P1监测其所辖小区的 PRB的使用率, 可选的宏 基站 M2亦可监测其所辖小区的 PRB的使用率;
在实际应用中, 网络中的基站可统计单位时长(单位时长可以为若干个时 隙、 几分钟, 几十分钟或其它的时长) 内其所辖一个或多个小区的上行 /下行 PRB的使用个数,计算出单位时长内该一个或多个小区的上行 /下行 PRB的使用 率 (下面用!^^表示上行 PRB的使用率), 其中, !^^等于单位时长内小区的 上行 PRB的使用个数与单位时长内该小区的 PRB的总数的比值。
因为小区的总的 PRB数是由小区的带宽决定的,所以上行 /下行 PRB的使用 率也可以通过使用的 PRB数来决定。此时 PRB使用率 =PRB使用数 /PRB总数(由 小区带宽决定)。 本发明实施例以 PRB使用率为例, 使用 PRB使用个数也是类 似的, 不在此——赘述。
其中, 计算 RURB的方式可如图 3所示, 例如设定单位时长为 20个时隙 (10 个 ΤΉ ) ,基站可统计出其所辖某小区每 2个时隙内上行 PRB的使用个数,而 RURB 则等于对应小区 20个时隙内上行 PRB的使用个数与该小区 20个时隙内上行 PRB的总数的比值。
在实际应用中, 可以根据具体应用场景设定冗余判决阈值 RRB-1 (例如为 90%、 80%或其它值)和 RRB-2 (例如为 95%、 100%或其它值), 若 RURB小于阈 值 RRB-1 , 则表示该基站所辖的对应小区存在冗余的上行 PRB, 若 RURB小于阈 值 RRB-2 , 则表示基站所辖的对应小区的上行 PRB不足。
因此, 宏基站 Ml和 Pico基站 P1 , 可选的宏基站 M2可根据监测到小区的上 行 /下行 PRB的使用率, 确定该小区是否存在冗余的上行 /下行 PRB , 或确定该 小区的上行 /下行 PRB是否不足。
可以理解的是, 若基站还需要监测小区下行 PRB的使用率 (下面用 RDRB 表示下行 PRB的使用率), 其统计计算方法类似, RDRB等于单位时长内小区的 下行 PRB的使用个数与单位时长内小区的下行物理资源块的总数的比值。宏基 站 Ml和 Pico基站 P1 , 可选的宏基站 M2也同样可根据监测到的小区下行 PRB的 使用率, 确定该小区是否存在冗余的下行 PRB, 或确定该小区下行 PRB是否不 足。
202、 宏基站 Ml和 Pico基站 P1交互所辖小区 PRB的使用情况, 可选的宏基 站 M2亦可与宏基站 Ml和 Pico基站 P1交互所辖小区 PRB的使用情况。
在一种应用场景下, 网络中各相邻小区的基站(即相邻基站 )间可通过基 站间直接接口或间接接口交互(一个或多个)相邻小区的 PRB的使用情况, 以 便于各基站根据交互信息获知相邻小区的 PRB的使用情况。
在实际应用中,相邻基站间可周期性的(具体的交互周期可根据具体场景 具体设定), 或在一种或多种触发事件的触发下, 交互相邻小区的 PRB的利用 情况。 举例来说, 触发事件 C1可为: 小区的上行 PRB (和 /或下行 PRB ) 的使 用率的变化幅度超过设定的阈值 (例如可为 20%、 40%或其它值); 触发事件 C2可为:上行 PRB的使用率与下行 PRB的使用率的比值的变化幅度超过设定的 阈值(例如为 10%、 20%或其它值)。
例如, 宏基站 Ml所辖的某小区 (表示为小区 Cml, 小区 Cml为宏小区) 与 Pico基站 P1所辖的某小区 (表示为小区 Cpl , 小区 Cp^Pico小区) 互为相邻小 区, 宏基站 M2所辖的某小区 (表示为小 Cm2 ) 与 Pico基站 PI所辖的小区 Cpl 互为相邻小区; 宏基站 Ml和 Pico基站 P1可周期性的, 或在触发事件 C1和 /或触 发事件 C2的触发下, 交互对应小区上行 /下行 PRB的使用情况, 宏基站 Ml可据 此获知 Pico基站 P 1下的小区 Cpl的上行 /下行 PRB是否不足。
类似的, 宏基站 M2和 Pico基站 P1亦可周期性的, 或在触发事件 C1和 /或触 发事件 C2的触发下, 交互对应小区上行 /下行 PRB的使用情况。
宏基站 Ml和 Pico基站 P1可在交互的负载相关消息、 指示无线资源状态的 消息或其它消息中携带 PRB的使用情况指示,该使用情况指示可指示出单位时 间内小区上行 /下行 PRB的使用率, 或指示出单位时间内小区上行 /下行 PRB的
使用个数, 或指示出该小区是否存在冗余的上行 /下行 PRB , 或指示出该小区 的上行 /下行 PRB是否不足, 或为指示出其它能够表征上行 /下行 PRB的使用情 况的信息, 基站根据交互信息获知相邻小区的 PRB的使用情况。
小区下行 PRB的不足可能通过下行 PRB的高使用率体现, 也可能通过以下 信息的一个或多个反映出来: 小区 Access class barring, 小区用户服务质量不 高或小区用户满意度低。
在实际应用中, 为减小基站间交互小区 PRB的使用情况的信令开销, 例如 可将对应平均 10个(或其它个数) PRB的使用作为一个等级, 当使用 PRB的变 化幅度达到 10个(或其它个数) PRB时,基站才进行交互。基站间交互小区 PRB 的使用情况也可用索引指示的方式进行,这样可很好的降低基站间交互的信令 开销。 表 1举例示出了一种索引 PRB使用数的对应关系:
以表 1示出的对应关系为例, 例如索引 0000指示出平均使用 10个 PRB, 索 引 1000指示出平均使用 90个 PRB, 依此类推。
203、 宏基站 Ml调整小区 Cm 々PRB的配置, 以将宏小区 Cml部分或全部冗 余的 PRB提供给 Pico基站用做小区的接入链路;
在一种应用场景下, 宏基站 Ml判决是否减少小区 Cml的下行 PRB的配置数 量, 可参考以下三个参考条件中的一个或多个进行:
参考条件一: 宏基站 Ml的小区 Cml的上行 PRB有冗余;
参考条件二: Pico基站 P1下与小区 Cml相邻的小区 (包括小区 CP1 ) 的下行 PRB不足;
参考条件三: 宏基站 Ml和 Pico基站 PI等相邻基站间存在较强的小区干扰 问题, 此时 Pico基站 P1可能在小区 CP1应用了 RE技术。 (由于小区 ( ^中有对相 邻小区 (包括小区 CP1 ) 的小区重选的偏置配置和测量上报的偏置配置, 宏基 站 Ml可据此获知与小区 Cml相邻的邻区 0^是否应用 RE配置)。
其中, 上述参考条件一是必选的参考条件, 参考条件二和参考条件三是可 选的参考条件。
宏基站 Ml可利用步骤 201和步骤 202获知小区 Cml和小区 Cp 々PRB的使用 情况。 宏基站 Ml可以根据参考条件一、 或根据参考条件一和参考条件二、 或 根据参考条件一和参考条件三、 或根据参考条件一和参考条件二及参考条件 三, 来判决是否调整小区 Cm 々PRB的配置。 当参考条件满足时, 宏基站 Ml可 决定减少小区 Cml的上行 PRB的配置数量, 以将小区 Cml部分或全部冗余的 PRB 提供给 Pico基站用做小区的接入链路。
为便于理解, 下面以宏小区 Cm^pPico小区 Cpl均为 FDD小区, 网络初始状 态下的小区频谱资源部署情况例可如图 4-a或图 4-b所示。
图 4-a和图 4-b所示的网络初始状态下, 宏小区 Cml和 Pico 'J、区 Cpl的上下行 频段部署为可相同, 上下行频段都为 20M带宽, 即 Pico小区上有虚框部分的频 谱配置。 也可以不同, 比如 Pico小区上无虚框部分的频谱配置。
宏基站 Ml可以根据宏小区 Cml的上行资源的冗余状况, 将宏小区 Cml的 PRB的位置 (包括数量)进行多种方式的调整, 减少宏小区 Cml上行 PRB的配 置数量, 将宏小区 0^冗余的部分或全部上行 PRB提供给 Pico基站 P1应用于其 小区接入链路, 而 Pico基站 P1则可根据宏基站 Ml对宏小区 Cm 々PRB的位置调 整, 对应来新部署一个(或多个) TDD配置兼容模式或非 TDD配置非兼容模式 的小区 (可称小区 Cp2 ), 可以理解, Pico基站 P1新部署的小区 Cp2与宏小区 Cml 互为相邻小区。
下面以异构网络为例来举例说明网络部署状态的各种变化,同构网络的情 况和异构网络是类似的。
调整场景 (一 ):
宏基站 Ml可减少宏小区 Cml的全部 FDD上行频段对应的子帧的数量,以将
冗余部分子帧提供给相邻小区 Cp2用作下行时隙配置。 例如网络小区部署状态 从图 4-a所示场景变化到图 4-c或图 4-d所示场景。
在例如图 4-c所示场景下, 宏基站 Ml调整宏小区 Cm 々 FDD上行子帧的位 置, 使得 Pico基站 P1可新部署 TDD模式的小区 Cp2。 其中, 图 4-c中以宏基站 Ml 置空其上行子帧中的第 0、 1以及 5、 6号子帧, 以便 Pico基站 P1将其配置为相邻 小区 Cp2的下行子帧为例, 当然还可以为其它的 TDD小区配置方式, 配置方式 类似, 此处不——赘述。 如表 2所示, 当前定义的 TDD模式的上下行时隙配比 关系包括如下 7种,在同一频段上满足如下 7种上下行时隙配比关系的配置方式 都是 TDD兼容配置。
表 2中, D表示上行子帧, U表示下行子帧, S表示转换子帧, 转换子帧可 看成是一种下行子帧, 图 4-c对应表 2中的 TDD配置 0。
同时, 为了避免宏小区 0^上行数据发送对相同频率上的相邻小区 Cp2的下 行数据接收的干扰,宏小区 ( ^在与小区 Cp2的下行传输时隙对应的 FDD上行时 隙位置不发送业务数据, 在该时隙对应上行控制信道可发送控制信令等。
其中, 在图 4-a和图 4-c所示场景中, Pico基站上可只有在 FDD UL频谱上的 小区, 也可以是除该小区外, 另外有 FDD小区, 该 FDD小区的上行子帧的位置 和该新部署小区的上行子帧的共享相同的资源。
对于从图 4-a变换到例如图 4-c的应用场景时, 宏小区和 /或 Pico小区上不同
的 TDD上下行子帧 (时隙) 的配比变化可如表 3所示。
表 3
在例如图 4-d所示场景下, 宏基站 Ml调整宏小区 Cm 々FDD上行子帧的位 置, 使得 Pico基站 P1可以新部署非 TDD配置兼容模式(灵活配置模式)的小区 Cp2。 其中, 图 4-d中以宏基站 Ml置空其上行子帧中的前四个子帧, 以便 Pico基 站 P1将其配置为相邻小区 Cp2的下行子帧为例, 当然还可以为其它非 TDD兼容 小区配置方式, 配置方式类似, 此处不——赘述。
在实际应用中,基站在下行时隙发送信号给用户设备, 该下行信号会经历 一定的信道, 从而导致到达用户的时候, 有一定的传输延迟。 而用户设备会在 上行时隙发送信号, 同样地, 该信号也会经历一定的传输延迟到达基站, 基站 端为了保持所有用户的上行时刻到达基站的一致,从而用户设备需要提前传输 延迟的时间来发送上行信号给基站。通常意义下可以认为, 上下行的传输延迟 是相同, 而且最大传播延迟与小区半径 R有关。 对于一个 TDD用户而言, 还需 要一定的从接收信号的状态转换成发送信号的状态的转换时间。
在例如图 4-c所示的 TDD配置方式中, 上下行之间的保护间隔 (GP )可重 用 TDD系统的 GP, 而在例如图 4-d所示的非 TDD兼容配置方式中, 由于下行时 隙的存在不满足标准定义的 TDD配置关系, 故而可重新配置 GP。
其中,获得 FDD UL载波上的下行时隙到上行时隙的之间的 GP例如可采用 :¾口下两种方式:
第一种方式: 置空(即挖掉)下行时隙和上行时隙相邻处的一个或多个下 行 OFDM符号和 /或上行 OFDM符号,以获得下行时隙和上行时隙之间的保护间 隔。 例如对于图 4-d所示的场景下, 基站可在 FDD UL 20M 频段中小区 Cp2的下 行子帧部分的结尾或者上行子帧部分的开始部分挖掉部分 OFDM符号,做下行 到上行转换时间和上行到下行转换时间的 GP , 该 GP也可以用作避免基站与基 站之间的干扰(上下行之间的干扰)。 该 GP需要考虑 N圏的宏基站, 例如若宏 小区的半径为 R, 那么 GP=N*2*R/C, C为光速。
第二种方式: FDD UL载波频段上的下行时隙或上行时隙向前 /后偏移 N个 OFDM符号, 以空出的 N个 OFDM符号用做 GP。
在上述两种方式中, 挖掉或偏移的 N个符号是可以配置, 也可以是预先设 置好的几种规定的配置方式,基站可以通知给其服务的用户设备相应的配置方 式或配置方式的索引, 用户设备据此获知 GP配置情况。
调整场景 (二):
宏基站 M 1可以减少宏小区 Cml的部分 FDD上行频段对应的子帧的数量,以 将冗余部分子帧提供给相邻小区 Cp2用作下行时隙配置。 例如网络小区部署状 态从图 4-b所示场景变化到图 4-e、 图 4-f、 图 4-g或图 4-h所示场景。
在例如图 4-e、 图 4-f所示场景下, 宏基站 Ml调整宏小区 Cm 々FDD上行子 帧的位置, 使得 Pico基站 P1可新部署的 TDD兼容模式的小区 Cp2。
其中, 图 4-e和图 4-f中以宏基站 M 1置空其部分 FDD上行子载波对应的上行 子帧中的第 0、 1以及 5、 6号子帧, 以便 Pico基站 P1将其配置为相邻小区 Cp2的 下行子帧为例, 当然还可为其它的 TDD兼容小区配置方式, 配置方式类似, 此 处不一一赞述。
在例如图 4-g和图 4-h所示场景下, 宏基站 Ml调整宏小区 Cml的部分 FDD 上行频段对应的上行子帧的位置,使得 Pico基站 P1也可新部署的非 TDD兼容模 式(灵活配置模式) 的小区 C p2。 其中, 图 4-g和图 4-h中以宏基站 Ml置空其部 分 FDD上行频段对应的上行子帧中的前四个子帧, 以便 Pico基站 P1将其配置为 相邻小区 C p2的下行子帧为例, 当然还可为其它灵活的非 TDD小区配置方式, 配置方式类似, 此处不——赘述。
同时, 为了避免小区 cpl上行数据发送对相同时隙的上的小区 cp2的下行数 据发送的干扰, Pico小区 CP1在与 Pico小区 Cp2的下行传输时隙对应的上行传输 时隙位置可不发送数据, 例如图 4-e、 图 4-f、 图 4-g或图 4-h所示。 为了支持旧版 本 UE, 可在置空 (挖掉) 时隙上, 可发送控制信令。 但如果对应的两个上行 频段的间隔较大, 则其干扰通常可忽略, 此时, Pico小区 CP1在与 Pico小区 Cp2 的下行时隙对应的上行时隙位置可发送数据和上行控制信令。
进一步的, 若 Pico小区 Cp2的下行传输时隙和与其与邻频的宏小区 Cml的上 行传输时隙的之间存在干扰的问题, 则宏小区 Cml上与 Pico小区 Cp2的下行传输 时隙邻频的上行传输时隙位置可不传输业务数据, 以避免相互间的干扰, 例如 图 4-f或图 4-h所示。 为了支持旧版本 UE (即不支持该配置方式的 UE ), 可在置 空 (挖掉) 的时隙上, 可发送控制信令。
对于从图 4-b变换到例如图 4-e的应用场景时, 宏小区和 /或 Pico小区上不同 的 TDD上下行子帧的配比变化可如表 4所示 (其中, 两个子载波频段分别以 10 个子帧进行计算)。
对于从图 4-b变换到例如图 4-f的应用场景时, 宏小区和 /或 Pico小区上不同 的 TDD上下行子帧的配比变化可如表 5所示 (其中, 两个子载波频段分别以 10 个子帧进行计算)。

6 D S U U U D S U U D 13 5 13:5 20 15 4:3 在一种应用场景下, 当宏基站 Ml决定提供宏小区 Cm 々FDD上行 PRB用作 Pico小区 CP2的下行时隙配置时, 宏基站 Ml可根据干扰的条件和 /或冗余的 PRB 数量等, 决定采用的调整方式, 调整宏小区 Cml的上行 PRB。
下面以调整场景(一)中的几种调整方式为例来进行说明,而调整场景(二) 的操作方法与调整场景(一)类似。
204、 宏基站 Ml向 Pico基站 P1发送消息 msl (例如, eNB配置更新消息或 小区激活消息、 或其它消息);
其中, 宏基站 Ml例如可以通过 eNB配置更新消息或小区激活消息 (消息 msl ), 通知 Pico基站 PI宏小区 Cml资源调整情况, 以便于 Pico基站 P1根据宏小 区 Cml的资源调整情况, 来配置新 Pico小区 Cpl。
在实际应用中, eNB配置更新消息或小区激活消息 (消息 msl )可以携带 用于指示出宏基站 Ml调整的小区 Cm2的物理资源块 PRB的调整数量的指示信 息, 该指示信息可包括如下信息的一种或多种: 宏基站 Ml所调整宏小区 Cml 资源的频点信息、 宏基站 Ml所调整宏小区 Cml资源的带宽信息、 宏基站 Ml所 调整宏小区 Cml资源的时隙个数信息、 宏基站 Ml所调整宏小区 Cml资源的时隙 位置信息、 上下行保护间隔的配置信息、 宏基站 Ml所调整宏小区 Cml 源的子 帧偏置信息。
进一步的, eNB配置更新消息或小区激活消息 (消息 msl )还可携带: 宏 基站 Ml所调整宏小区 Cml 源的用途信息(例如指示用于配置无线回程链路或
配置 Pico小区的接入链路或节能配置),和 /或,宏小区 Cml资源调整的激活时间 信息等。
进一步的, eNB配置更新消息或小区激活消息 (消息 msl )还可携带: 用 于指示 Pico基站 P1配置小区的下行无线接入链路和上行无线接入链路的保护 间隔的保护间隔配置指示, 其中, 保护间隔配置指示可用于指示出: 在相邻的 一个或多个下行传输符号和 /或上行传输符号上不进行数据的传输, 以将该一 个或多个下行传输符号和 /或者上行传输符号作为保护间隔; 或者, 将相邻的 一个或多个下行传输符号和 /或者上行传输符号向前或向后偏移一个或多个符 号, 以将偏移空出的传输符号作为保护间隔。
当然, eNB配置更新消息或小区激活消息 (消息 msl )也可以不携带上述 信息中的一个或多个, 基站间可采用默认方式确认对应的配置。 例如, 若指示 信息中不包括宏基站 Ml所调整宏小区 Cml资源的频点信息、 宏基站 Ml所调整 宏小区 Cml资源的带宽信息, 此时, Pico基站 P1可默认为宏基站 Ml所调整宏小 区 Cml资源的频点为小区下行频段对应的起始频点, 宏基站 Ml所调整宏小区 Cml资源的带宽为小区下行频段对应的带宽, 以此类推。 或者, 基站间也可以 协议规定一种或几种固定的资源调整方式,基站之间可直接交互资源调整的方 式信息或者只交互资源调整方式对应的索引信息,即可将资源调整情况通知对 端。 当然, 如果只有一种资源调整方式, 则可只需要通知对端是否调整资源即 可。
205、 宏基站 Ml向宏基站 M2发送消息 ms2 (例如, eNB配置更新消息或小 区激活消息、 或其它消息);
相应的, 宏基站 Ml例如还可通过 eNB配置更新消息或小区激活消息 (消 息 ms2 ), 通知宏基站 M2宏小区 Cml 源调整情况。
在实际应用中, eNB配置更新消息或小区激活消息 (消息 ms2 )可携带指 示出宏基站 Ml调整的宏小区 Cml的物理资源块 PRB的调整数量的指示信息, 该 指示信息可以包括如下信息的一种或多种:宏基站 Ml所调整宏小区 Cml资源的 频点信息、 宏基站 Ml所调整宏小区 Cml资源的带宽信息、 宏基站 Ml所调整宏 、区 Cml资源的时隙个数信息、 宏基站 M 1所调整宏小区 Cml资源的时隙位置信
息、 上下行保护间隔的配置信息、 宏基站 Ml所调整宏小区 Cml 源的子帧偏置 信息。
进一步的, eNB配置更新消息或小区激活消息 (消息 ms2 )还可携带: 宏 基站 Ml所调整宏小区 Cml 源的用途信息(例如指示用于配置 Pico小区的接入 链路或配置无线回程链路或节能配置), 和 /或, 宏小区 Cml资源调整的激活时 间信息等。
当然, eNB配置更新消息或小区激活消息 (消息 ms2 )也可不携带上述信 息中的其中一个或多个,而基站间可采用默认方式确认对应的配置方式。例如, 若指示信息中不包括宏基站 Ml所调整宏小区 Cml资源的频点信息、 宏基站 Ml 所调整宏小区 Cml资源的带宽信息, 此时, 宏基站 M2可默认为宏基站 Ml所调 整宏小区 Cml资源的频点为小区下行频段对应的起始频点,宏基站 Ml所调整宏 小区 Cml资源的带宽为小区下行频段对应的带宽, 以此类推。 或者, 基站间也 可以协议规定一种或几种固定的资源调整方式,基站之间可直接交互资源调整 的方式信息或者只交互资源调整方式对应的索引信息,即可将资源调整情况通 知对端。 当然, 如果只有一种资源调整方式, 则可只需要通知对端是否调整资 源即可。
宏基站 M2可以根据 eNB配置更新消息或小区激活消息 (消息 ms2 ), 变更 所辖的小区 CP2的相邻小区的上行 PRB配置, 以避免产生小区干扰。
可以理解, 宏基站 Ml、 宏基站 M2和 Pico基站 PI之间, 可通过基站间直接 的接口, 比如 X2、 Iur、 Iub或空口; 或通过基站间间接的接口, 比如 SI , Iu 口交互信息。
206、 宏基站 Ml通知驻留在小区 Cml下的 UE小区 Cml配置变更;
在一种应用场景下,宏基站 Ml在更改或准备更改小区 Cm 々上行资源配置 时, 若服务的部分 UE (例如 R10版本的 UE ) 支持小区 ( ^这种新的 UL子帧的 配置方式, 而小区 Cml这种新的上行子帧配置做特殊的 HARQ反馈设计时, 宏 基站 Ml可在空口, 以广播方式或者单播方式, 向新版本 UE通知小区 Cml更改 的 UL子帧 (时隙) 配置, 而对于旧版本的 UE可不进行通知。
其中, 宏基站 Ml可向其服务的部分或全部 UE发送服务小区更新配置信
息, 该服务小区更新配置信息如下信息的一种或多种:
所调整小区 Cml资源的上行和 /或下行频点信息、 所调整小区 Cml 源的上 行和 /或下行带宽信息、调整小区 Cml资源后的空白(mute )子帧的上行和 /或下 行位置信息、 小区 Cml资源调整的激活时间信息。
对于 Pico基站可能配置非 TDD配置兼容小区的情况, 宏基站 Ml对其下的 新版本的 UE的空口通知方式有广播方式(通过系统广播消息 )和单播方式(通 过专用信令消息)。
其中, 宏基站 Ml若采用广播方式通知 UE, 宏基站 Ml可将小区 Cml的上行 mute子帧 (时隙) 的配置信息放到 SIB2上, 其格式可如下所示:
Systemlnformation BlockType2 information element
freqlnfo SEQUENCE {
ul-CarrierFreq ARFCN-ValueEUTRA OPTIONAL, Need OP ul-Bandwidth ENUMERATED {n6, nl5, n25, n50 n75, nlOO} OPTIONAL, - Need OP
Mute UL configuration SEQUENCE {
ul-CarrierFreq ARFCN-ValueEUTRA
ul-Bandwidth ENUMERATED {n6, nl5, n25, n50, n75, nlOO} Mute position BIT STRING ( SIZE ( 10 ) )
宏基站 Ml可将小区 Cml的下行 mute子帧的配置信息放到 MIB或者 SIB2上; 其中, 放到 MIB上的格式可为:
Master InformationBlock ( MIB )
- ASN1 START
MasterlnformationBlock:: =
SEQUENCE {
dl-Bandwidth ENUMERATED {n6, nl5, n25, n50, n75, nlOO},
Mute UL configuration BIT STRING ( SIZE(IO )
phich-Config PHICH-Config,
systemFrameNumber BIT STRING ( SIZE ( 8 ) ), spare BIT STRING ( SIZE ( 10 ) )
- ASN1STOP 放到 SIB2上的格式可以为:
SystemInformationBlockType2 information element
freqlnfo
SEQUENCE {
ul-CarrierFreq ARFCN-ValueEUTRA OPTIONAL, - Need OP ul-Bandwidth ENUMERATED {n6, nl5, n25, n50, n75, nlOO} OPTIONAL, - Need OP
Mute DL configuration BIT STRING ( SIZE ( 10 ) )
此外, 若使用专用信令通知 UE, 小区 Cm 々上下行 mute的信息可在携带在 多种下行的信令中传输, 例如寻呼消息, 连接建立消息, 连接重配置消息, 连 接重建立消息, 下行消息传输消息中。
207、 Pico基站 P1配置新 Pico小区 CP2;
其中, Pico基站 P1可根据宏小区 Cml¾供上行资源, 以及相邻小区对宏小 区 Cml的干扰状况,确定使用宏小区 Cml提供的上行资源部署 Pico小区 CP2,新部 署 Pico小区 CP2可看成将小区的无线接入链路的资源从无调整为有或者从一种 配置调增到另一种配置。
新部署 Pico小区 CP2的上下行子帧 (时隙) 配比:
Pico基站 P1可以根据宏小区 Cml提供上行资源的子帧数和 TDD小区配置模 式进行匹配, 得到满足 TDD小区配置模式的 Pico小区 CP2上下行子帧配比。 或 者, Pico基站 P1亦可根据 HARQ时隙和上下行调度的处理需要, 确定 Pico小区 CP2的上下行子帧 (时隙) 配比。
下面主要以将 Pico小区 CP2配置为 TDD兼容配置小区(即 Pico基站 P1新部署 一个 TDD小区) 为例进行描述, 而将 Pico小区 CP2配置为一个非 TDD兼容配置
小区 (即灵活的上下行配置) 的上下行配置的情况也类似。
以图 4-c所示场景为例, 宏小区 Cm 々FDD UL可以提供 4个下行子帧, 因为 S子帧也看成是下行子帧, 所以 FDD UL提供给的 4个下行子帧可以是 2个 DL子 帧和 2个 S子帧, 也可以是 3个 DL子帧和 1个 S子帧, 此时对应表 2中的 TDD配置 为配置方式 0。而宏基站 Ml则可根据 Pico基站的配置 TDD的 Pico小区 CP2的上下 行子帧 (时隙) 的位置关系, 决定在宏小区 0^部分或全部上行频段的哪些子 帧 (时隙 )位置不发送业务数据。
对于灵活的上下行配置的情况下 (即配置非 TDD兼容配置小区), Pico小 区 CP2的上下行子帧的位置可由有效的 HARQ时序来决定的。 例如为 FDD或 TDD、 或 FDD结合 TDD方式, 或者新定义的时序关系。
此前, 基站间还可交互各自的硬件处理能力(包括发射和接收能力, 例如 发射机个数和 /或接收机个数等), 或者未激活的非完整的小区配置信息。 对于 基站可增加一个小区而没有频谱资源的小区配置能力, 也可以通知给相邻基 站。 该交互信息可在基站间接口建立时发送, 也可在后续的接口信令中交互。
比如, 为了支持在 FDD UL频段上进行下行发送, 需要在该基站上增加一 个新的发射通道。 如果宏基站 Ml (资源提供基站)获知 Pico基站 P1具有新增 发射通道的能力, 则宏基站 Ml可以有针对性的向 Pico基站 P1发送消息, 向其 提供 FDD UL频段资源。
Pico基站 P1上可以先配置部分小区 CP2信息 (尽管小区 CP2在未配置上下行 资源前处于未运行的去激活状态), 并和相邻基站 (包括宏基站 Ml和宏基站 M2 )进行交互, 其中, 基站间交互的小区 CP2的部分配置信息可包括如下信息 的一种或多种:
小区 CP2的物理层小区标识, 高层小区标识, 跟踪区码, PLMN标识等; 小区 CP2的工作模式为 TDD模式还是 FDD模式(可选的);
小区 CP2的状态 (未完全配置时为去激活状态)。
此外, 若基站间不交互基站的硬件处理能力, 则可提供资源的基站可向部 分或全部相邻基站发送 FDD UL资源提供信息, 而具有相应硬件处理能力的相 邻基站可对应的响应。
在一种应用场景下, 宏基站 Ml (提供上行 FDD UL资源的基站)向 Pico基 站 P1 (接收上行资源的基站)发送 eNB配置更新消息(消息 msl ) , 在 eNB配置 更新消息中携带宏基站 Ml提供的调整的宏小区 CmlFDD上行资源的配置,并指 明所调整上行资源的用途。
在实际应用中,宏基站 Ml ( donor基站)可在第一条 eNB配置更新消息(消 息 msl ) 中的修改的服务小区信息中的 FDD信息中, 发送 TDD小区具体配置给 Pico基站 P1 , 即宏基站 Ml决定相邻小区 TDD配置, 具体可如表 6所示, 但不局 限于此:
表 6
其中, 对于新增加的 IE Muted UL config, 其具体的配置可如表 7所示, 但 不局限于此:
或者, muted子帧的配置也可以不使用 bitmap方式指示, 而是使用对应的 TDD配置方式指示, 即指示 TDD配置 0到 TDD配置 6中的一种。 TDD下行子帧 对应的时隙位置就是宏基站 Ml mute掉的宏小区 CmlUL子帧的时隙位置。
当相邻的 Pico基站 P1收到携带上述配置信息的消息后,若获知 mute上行资 源配置的原因是要配置 TDD接入链路,那么 Pico基站 P1可根据 mute上行配置中 的上行的频点和带宽来相应的配置 TDD小区的频点和带宽, 此外, 若 FDD UL 资源小区决定 TDD小区配置的话, 则宏基站 Ml可在 mute子帧配置信息中会给 包含出 mute子帧的具体时隙位置。 Pico基站 P1的相邻小区可直接根据该 mute子 帧的时隙位置, 决定 TDD小区的上下行配比和配置的起始位置。 然后, Pico基 站 P1基站为该小区配置 ECGI, PCI, TAC, PLMN等参数, 并向相邻基站发送 eNB配置更新消息。
此外, 宏基站 Ml源 eNB的 mute上行资源 UL配置信息中, Mute 子帧配置 部分还可以只配置子帧个数,具体的 TDD小区配置由配置 TDD小区的 Pico基站 P1来决定。
若按照表 8所示的配置方式, 宏基站 Ml可在收到 Pico基站 PI发送的包含 TDD小区配置的 eNB配置更新消息后, 才按照 Pico基站 P1配置的 TDD小区的下 行子帧所在的位置进行宏小区 Cml的上行子帧的非调度操作 ( mute )。
进一步的, Pico基站 P1可在 eNB配置更新消息中可携带详细的新小区配置 的信息, 例如表 9所示。
Pico基站 P1配置新增小区, 包括 TDD方式配置或非 TDD兼容方式配置。 在 TDD兼容的配置方式中,除了频点,带宽和 TDD配比以及特殊子帧配置 外, 还有 CP的配置。 可能需要新增加的配置为子帧配置量和配置生效的激活 时间等。
对于非 TDD兼容的配置方式, 除了频点, 带宽外, 还需要新配置上下行的 子帧位置, 下行到上行转换的 GP配置, 上行到下行保护间隔的配置。 在 mute symbol config中可配置 mute symbol是上行符号, 还是下行符号, mute掉几个符 号等。 或者, 配置移动的符号为上行符号, 还是下行符号, 移动几个符号等。 在调度的 SRS配置中, 可包括是否进行 SRS配置, 配置的 SRS的符号数等。

可以理解, 若宏基站 Ml的指示的小区配置 Pico基站 PI都可接受的话, 则 相应标灰的 IE也可省略。
另外, 在显示激活指示方式中, 宏基站 Ml也可不指定具体的配置, 只 示部分的小区配置, Pico基站 P1决定具体如何调整小区的配置, 其具体配 如下表 12所示:
表 12
在这种配置下, Pico基站 PI对于调整小区激活的相应信息中需要反馈具体 的小区的配置信息, 然后提供宏基站 Ml可以根据 Pico基站 P1反馈的小区配置 来配置宏小区 Cml的非调度上行子帧。

209、 Pico基站 P1通知其服务的 UE小区配置变更;
在一种应用场景下, Pico基站 P1可通过系统消息或者专用信令, 向其服务 的部分或全部用户终端(例如可只向 R10等新版本 UE通知小区配置变更, 或向 所有 UE通知小区配置变更)发送服务小区更新配置信息, 该服务小区更新配 置信息如下信息的一种或多种: 所调整 Pico小区 CP2资源的上行和 /或下行频点 信息、 所调整 Pico小区 CP2资源的上行和 /或下行带宽信息、 Pico小区 CP2资源调 整的激活时间信息、 上下行保护间隔的配置信息等信息。

在一种应用场景下, 宏基站 Ml若根据监测到小区 Cml的上行 PRB的使用率 确定小区 Cml还存在冗余的上行 PRB , 则可减少小区 Cml的上行 PRB的配置数 量;若根据监测到小区 Cml的上行 PRB的使用率确定小区 Cml的上行物理资源块 不足,则可增加小区 Cml的上行 PRB的配置数量,此时,宏基站 Ml可先指示 Pico 基站 PI减少 Pico小区 Cp2的下行 PRB的配置数量, 并在 Pico基站 P1对应减少 Pico 小区 Cp2的下行 PRB的配置数量后, 增加小区 Cml的上行 PRB的配置数量。
213、 宏基站 Ml向 Pico基站 P1发送消息 ms3 (例如为, eNB配置更新消息 或小区激活消息、 或其它消息);

214、 宏基站 Ml可向宏基站 M2发送消息 ms4 (例如为, eNB配置更新消息 或小区激活消息、 或其它消息);

宏基站 M2可以根据 eNB配置更新消息或小区激活消息 (消息 ms4 ), 变更 所辖的小区 Cp2的相邻小区的上行 PRB配置, 以避免产生干扰。
215、 Pico基站 P1调整 Pico小区 CP2配置;
其中, Pico基站 P1可根据调整的宏小区 Cml的资源配置情况, 以及相邻小 区对宏小区 Cml的干扰状况, 确定如何调整 Pico小区 CP2的资源配置。
在一种应用场景下, 若宏基站 Ml减少小区 Cml的上行 PRB的配置数量, 则 Pico基站 P1可对应增加 Pico小区 CP2的下行 PRB配置数量, 或者也可不改变 Pico 小区 CP2的下行 PRB配置数量; 若宏基站 Ml增加小区 Cml的上行 PRB的配置数 量, 则 Pico基站 P1可对应减少 Pico小区 Cp2的下行 PRB的配置数量。
216、 Pico基站 P1向宏基站 Ml发送消息 ms32 (例如为, eNB配置更新响应 消息或小区激活响应消息或 eNB配置更新消息、 或其它消息), 以向其通知小 区 CP2更新的配置;
217、 宏基站 M2可向宏基站 Ml发送消息 ms42 ( eNB配置更新响应消息或 小区激活响应消息或 eNB配置更新消息、 或其它消息), 以向其通知相邻小区 更新的配置;

由上可见, 本实施例的方案中, 小区上行资源冗余的宏基站通过调整该小 区的资源配置, 将该小区冗余的部分或全部资源提供给与之相邻的 Pico基站用 于配置小区无线接入链路和 /或无线回程链路,而 Pico基站则根据宏基站对小区 的资源配置的调整, 来对应的调整其小区无线接入链路的资源配置, 该机制有 利于提高资源的利用效率, 提升系统性能和服务质量。 实施例三
为便于更好的理解,下面以某个宏基站将其冗余的 UL/DL频谱资源提供给 某个 Pico基站应用于其无线接入链路和无线回程链路的过程为例, 对本发明实 施例的技术方案进行更为详细的描述。
参见图 5,例如宏基站 Ml和宏基站 M2为 Pico基站 P1的相邻基站,本发明实 施例中频谱资源的配置调整方法的另一个实施例, 具体可包括:
501、 宏基站 Ml和 Pico基站 P1监测其所辖小区的 PRB的使用率;
502、 宏基站 Ml和 Pico基站 P1交互所辖小区 PRB的使用情况;
步骤 501~502与步骤 201~202的实现方式类似。
503、 宏基站 Ml调整小区 Cm 々PRB的配置, 以将宏小区 Cml部分或全部冗 余的 PRB提供给 Pico基站用做小区的无线接入链路或无线回程链路;
在一种应用场景下, 宏基站 Ml判决是否减少小区 Cml的下行 PRB的配置数 量, 可参考以下三个参考条件中的一个或多个进行:
参考条件一: 宏基站 Ml的小区 Cml的上行 PRB有冗余;
参考条件二: Pico基站 P1下与小区 Cml相邻的小区 (包括小区 CP1 ) 的下行 PRB不足;
参考条件三: 宏基站 Ml和 Pico基站 P1等相邻基站间存在较强的小区干扰 问题, 此时 Pico基站 P1可能在小区 CP1应用了 RE技术。 (由于小区 ( ^中有对相 邻小区 (包括小区 CP1 ) 的小区重选的偏置配置和测量上报的偏置配置, 宏基 站 Ml可据此获知与小区 Cml相邻的邻区 0^是否应用 RE配置)。
其中, 上述参考条件一是必选的参考条件, 参考条件二和参考条件三是可 选的参考条件。
宏基站 Ml可利用步骤 201和步骤 202获知小区 Cml和小区 Cp 々PRB的使用 情况。 宏基站 Ml可以根据参考条件一、 或根据参考条件一和参考条件二、 或 根据参考条件一和参考条件三、 或根据参考条件一和参考条件二及参考条件 三, 来判决是否调整小区 Cm 々PRB的配置。 当参考条件满足时, 宏基站 Ml可 决定减少小区 Cml的下行 PRB的配置数量, 以将小区 Cml部分或全部冗余的 PRB 提供给 Pico基站用做小区的接入链路。
为便于理解, 下面以宏小区 Cm^pPico小区 Cpl均为 FDD小区, 网络初始状 态下的小区频谱资源部署情况例可如图 4-a或图 4-b所示。
图 4-a和图 4-b所示的网络初始状态下, 宏小区 Cml和 Pico 'J、区 Cpl的上下行 频段部署为可相同, 上下行频段都为 20M带宽, 即 Pico小区上有虚框部分的频 谱配置。 也可以不同, 比如 Pico小区上无虚框部分的频谱配置。
宏基站 Ml可以根据宏小区 Cml的上行资源的冗余状况, 将宏小区 Cml的 PRB的位置 (包括数量)进行多种方式的调整, 减少宏小区 Cml上行 PRB的配 置数量, 将宏小区 0^冗余的部分或全部上行 PRB提供给 Pico基站 P1应用于其 小区接入链路和无线回程链路, 而 Pico基站 P1则可根据宏基站 Ml对宏小区 Cml 的 PRB的位置调整,对应来新部署一个 TDD模式或非 TDD兼容模式的小区(可 称小区 Cp2 ), 以及配置无线回程链路。 可以理解, Pico基站 P1新部署的小区 Cp2 与宏小区 Cml 为相邻小区。
下面以异构网络为例来举例说明网络部署状态的各种变化,同构网络的情 况和异构网络是类似的。
调整场景 (三 ):
宏基站 Ml可减少宏小区 Cml的全部 FDD上行频段对应的子帧数量,以将冗 余部分子帧提供给 Pico基站 P1用作相邻小区 Cp2的下行时隙配置。 例如网络小 区部署状态从图 4-a所示场景变化到图 6-a所示场景。
宏基站 Ml调整宏小区 Cm 々FDD上行子帧的位置, 使得 Pico基站 P1可新部 署无线回程链路, 其中, 无线回程的频谱资源完全来自于 FDD UL频段。 在宏
基站 Ml侧, 无线回程的上下行链路和 FDD系统的 UL反馈链路以时分方式共享 FDD的上行频段。 在 pico基站 P1侧, 无线回程的上下行链路和 FDD系统的 UL 反馈链路以时分方式共享 FDD的上行频段。
在例如图 6-a所示场景下, 其中,
宏小区的接入链路:
DL (从宏小区到 UE ): 使用宏小区 FDD的 DL频段的 0 ~ 9号子帧;
UL (从 UE到宏小区): 使用 FDD的 UL频段中的部分子帧, 包括: 2 ~ 4号 子帧和 7 ~ 9号子帧。 其中, 在 2、 4、 7、 9号上行子帧位置, 无线回程链路的上 行和宏小区 Cm2的上行接入链路复用相同的上行时隙, 复用方式可以是基于频 分、 时分或资源块分。
pico小区的接入链路:
DL (从 pico小区到 UE ): 使用 pico小区 FDD的 DL频段的 0 ~ 9号子帧; UL (从 UE到 pico小区): 使用 pico 'J、区 FDD的 UL频段中的部分子帧, 包括 3和 8号子帧;

DL (从宏小区到 pico小区): 使用 FDD的 UL频段中的部分子帧, 包括: 宏 小区 FDD的 UL频段中的 0 ~ 1号子帧和 5 ~ 6号子帧, 和, pico小区 FDD的 UL频 段中的 0 ~ 1号子帧和 5 ~ 6号子帧;
UL (从 pico小区到宏小区): 使用 FDD的 UL频段中的部分子帧, 包括: 宏 小区和 Pico小区的 FDD的 UL频段中的 2和 4号子帧和 7和 9号子帧。
当然还可为其它的 TDD小区和无线回程配置方式, 配置方式类似,此处不 ' ■赞述。
调整场景 (四 ):
宏基站 Ml可以调整宏小区 Cm 々FDD上行和下行频段的子帧数量,以将冗 余部分子帧提供给 Pico基站 P1用作无线回程链路金额相邻小区 Cp2的上行或下 行时隙配置。
例如网络小区部署状态从图 4-a所示场景变化到图 6-b所示场景。
在该调整方案中, 无线回程链路的频谱资源来自于 FDD DL和 UL频段。 在
宏基站侧和 pico基站侧,下行回程链路和 FDD系统的 DL接入链路共享 FDD的下 行频段, 同时上行回程链路和 FDD系统的 UL接入链路共享 FDD的上行频段。 在例如图 6-b所示场景下, 其中,
宏小区的接入链路:
DL (从宏小区到 UE): 使用宏小区 FDD的 DL频段中的部分子帧, 包括 0 ~ 1号子帧, 和, 5~6号子帧, 对于子帧 2~4以及子帧 7~9, 宏小区的下行接入链 路可以和回程的下行链路以时域、 频域、 资源块方式进行复用;
UL (从 UE到宏小区): 使用宏小区 FDD的 UL频段中的部分子帧, 包括 2 ~ 4号子帧, 和, 7~9号子帧; 对于子帧 0~1以及子帧 5~6, 宏小区的上行接入链 路可以和回程的上行链路以时域、 频域、 资源块方式进行复用;
Pico小区的接入链路, pico基站有 2条接入链路:
FDD的接入链路:
DL (从 pico小区到 UE): 使用 Pico小区 FDD的 DL频段中的部分子帧, 包括 0~1号子帧, 和, 5~6号子帧;
UL (从 UE到 pico小区): 使用 Pico 'J、区 FDD的 UL频段中的部分子帧, 包括 2~4号子帧, 和, 7~9号子帧;
TDD的接入链路:
DL (从 pico 'J、区到 UE ): 使用 Pico 'J、区 FDD的 UL频段中的部分子帧, 包括 0~1号子帧, 和, 5 ~ 6号子帧;
UL (从 UE到 pico小区): 使用 Pico 'J、区 FDD的 UL频段中的部分子帧, 包括 2~4号子帧, 和, 7~9号子帧;
无线回程链路:
DL (从宏小区到 pico小区): 使用 FDD的 DL频段中的部分子帧, 包括: 宏 'J、区 FDD的 DL频段中的 2 ~ 4号子帧和 7 ~ 9号子帧, 和, pico 'J、区 FDD的 DL频 段中的 2 ~ 4号子帧和 7 ~ 9号子帧。
UL (从 pico小区到宏小区): 使用 FDD的 UL频段中的部分子帧, 包括: 宏 小区 FDD的 UL频段中的 0 ~ 1号子帧和 5 ~ 6号子帧, 和, pico小区 FDD的 UL频 段中的 0~ 1号子帧和 5 ~ 6号子帧。 其中, 在 pico小区 FDD的 UL频段中, Pico
小区的下行接入链路( Pico小区到 UE )和上行无线回程链路( Pico小区到 Macro 小区)是复用相同的子帧时隙 (0 ~ 1号子帧和5 ~ 6号子帧)。 复用方式可以是 基于频分、 时分或资源块分。
可以看出, 图 6-b调整的接入链路和无线回程链路满足 TDD兼容的上下行 时隙配置关系。
而图 6-c调整的接入链路满足非 TDD兼容的配置关系, 可看成是一种灵活 的配置关系。 在例如图 6-c所示场景下, 其中,
宏小区的接入链路:
DL (从宏小区到 UE ): 使用宏小区 FDD的 DL频段中的部分子帧, 包括 0 ~ 3号子帧,对于子帧 4~9,宏小区的下行接入链路可以和回程的下行链路以时域、 频域、 资源块方式进行复用;
UL (从 UE到宏小区): 使用宏小区 FDD的 UL频段中的部分子帧, 包括 4 ~ 9号子帧,对于子帧 4~9,宏小区的上行接入链路可以和回程的上行链路以时域、 频域、 资源块方式进行复用;
Pico小区的接入链路, pico基站有 2条接入链路:
FDD的接入链路:
DL (从 pico小区到 UE ): 使用 Pico小区 FDD的 DL频段中的部分子帧, 包括 0 ~ 3号子帧;
UL (从 UE到 pico小区): 使用 Pico 'J、区 FDD的 UL频段中的部分子帧, 包括 4 ~ 9号子帧;
接入链路 2:
DL (从 pico 'J、区到 UE ): 使用 Pico 'J、区 FDD的 UL频段中的部分子帧, 包括 0 ~ 3号子帧;
UL (从 UE到 pico小区): 使用 Pico 'J、区 FDD的 UL频段中的部分子帧, 包括 4 ~ 9号子帧;
无线回程链路:

子帧。
UL (从 pico小区到宏小区): 使用 FDD的 UL频段中的部分子帧, 包括: 宏 小区 FDD的 UL频段中的 0 ~ 3号子帧, 和, pico小区 FDD的 UL频段中的 0 ~ 3号 子帧。 其中, 在 pico 'J、区 FDD的 UL频段中, Pico小区的下行接入链路 ( Pico 小区到 UE )和上行无线回程链路(Pico小区到 Macro小区)是复用相同的子帧 时隙 (0 ~ 3号子帧)。 复用方式可以是基于频分、 时分或资源块分。
当然还可为其它的小区无线链路和无线回程配置方式, 配置方式类似, 此 处不一一赞述。
在一种应用场景下, 当宏基站 Ml决定提供宏小区 Cml的 FDD上行 PRB用作 无线回程链路和 Pico小区 CP2的下行时隙配置时, 宏基站 Ml可根据干扰的条件 和冗余的 PRB数量等, 决定采用的调整方式, 调整宏小区 Cml的上行 PRB。
504、 宏基站 Ml向 Pico基站 PI发送消息 ms51 (例如为, eNB配置更新消息 或小区激活消息 ms51、 或其它消息);
其中, 宏基站 Ml例如可通过 eNB配置更新消息或小区激活消息 (消息 ms51 ), 通知 Pico基站 PI宏小区 Cml 源调整情况, 以便于 Pico基站 P1根据宏小 区 Cml的资源调整情况, 来配置新 Pico小区 Cp2和回程链路。
在实际应用中, eNB配置更新消息或小区激活消息消息 ms51 )可携带用于 指示出宏基站 Ml调整的小区 Cm2的物理资源块 PRB的调整数量的指示信息, 该 指示信息可包括如下信息的一种或多种:宏基站 Ml所调整宏小区 Cml 源的频 点信息、 宏基站 Ml所调整宏小区 Cml资源的带宽信息、 宏基站 Ml所调整宏小 区 Cml资源的时隙个数信息、宏基站 Ml所调整宏小区 Cml资源的时隙位置信息、 上下行保护间隔的配置信息、 宏基站 Ml所调整宏小区 Cml资源的子帧偏置信 息。
进一步的, eNB配置更新消息或小区激活消息(消息 ms51 )还可携带: 宏 基站 Ml所调整宏小区 Cml 源的用途信息(例如指示用于配置无线回程链路和 配置 Pico小区的接入链路或节能配置),和 /或,宏小区 Cml资源调整的激活时间 信息等。 当然, eNB配置更新消息或小区激活消息(消息 ms51 )也可不携带上 述信息中的一个或多个, 基站间可采用默认方式确认对应的配置。 例如, 若指
示信息中不包括宏基站 Ml所调整宏小区 Cml资源的频点信息、 宏基站 Ml所调 整宏小区 Cml资源的带宽信息, 此时, Pico基站 P1可默认为宏基站 Ml所调整宏 小区 Cml资源的频点为小区下行频段对应的起始频点,宏基站 Ml所调整宏小区 Cml资源的带宽为小区下行频段对应的带宽, 以此类推。 或者, 基站间也可以 协议规定一种或几种固定的资源调整方式,基站之间可直接交互资源调整的方 式信息或者只交互资源调整方式对应的索引信息,即可将资源调整情况通知对 端。 当然, 如果只有一种资源调整方式, 则可只需要通知对端是否调整资源即 可。
505、 宏基站 Ml向宏基站 M2发送消息 ms52 (例如为, eNB配置更新消息 或小区激活消息 ms52、 或其它消息);
相应的, 宏基站 Ml还可通过 eNB配置更新消息或小区激活消息 (消息 ms52 ), 通知宏基站 M2宏小区 Cml 源调整情况。
在实际应用中, eNB配置更新消息或小区激活消息(消息 ms52 )可携带指 示出宏基站 Ml调整的宏小区 Cml的物理资源块 PRB的调整数量的指示信息, 该 指示信息可以包括如下信息的一种或多种:宏基站 Ml所调整宏小区 Cml资源的 频点信息、 宏基站 Ml所调整宏小区 Cml资源的带宽信息、 宏基站 Ml所调整宏 、区 Cml资源的时隙个数信息、 宏基站 M 1所调整宏小区 Cml资源的时隙位置信 息、 上下行保护间隔的配置信息、 宏基站 Ml所调整宏小区 Cml 源的子帧偏置 信息。
进一步的, eNB配置更新消息或小区激活消息(消息 ms52 )还可携带: 宏 基站 Ml所调整宏小区 Cml 源的用途信息(例如指示用于配置 Pico小区的接入 链路或配置无线回程链路或节能配置), 和 /或, 宏小区 Cml资源调整的激活时 间信息等。
当然, eNB配置更新消息或小区激活消息(消息 ms52 )也可不携带上述信 息中的其中一个或多个,而基站间可采用默认方式确认对应的配置方式。例如, 若指示信息中不包括宏基站 Ml所调整宏小区 Cml资源的频点信息、 宏基站 Ml 所调整宏小区 Cml资源的带宽信息, 此时, 宏基站 M2可默认为宏基站 Ml所调 整宏小区 Cml资源的频点为小区下行频段对应的起始频点,宏基站 Ml所调整宏
小区 Cml资源的带宽为小区下行频段对应的带宽, 以此类推。 或者, 基站间也 可以协议规定一种或几种固定的资源调整方式,基站之间可直接交互资源调整 的方式信息或者只交互资源调整方式对应的索引信息,即可将资源调整情况通 知对端。 当然, 如果只有一种资源调整方式, 则可只需要通知对端是否调整资 源即可。
宏基站 M2可以根据 eNB配置更新消息或小区激活消息(消息 ms52 ), 变更 所辖的小区 CP2的相邻小区的上行 PRB配置, 以避免产生小区干扰。
可以理解, 宏基站 Ml、 宏基站 M2和 Pico基站 PI之间, 可通过基站间直接 的接口, 比如 X2、 Iur、 Iub或空口; 或通过基站间间接的接口, 比如 SI , Iu 口交互信息。
506、 宏基站 Ml通知其服务的 UE小区 Cml配置变更;
在一种应用场景下,宏基站 Ml在更改或准备更改小区 Cm 々上行资源配置 时, 若服务的部分 UE (例如 R10版本的 UE ) 支持小区 ( ^这种新的 UL子帧的 配置方式, 而小区 Cml这种新的上行子帧配置做特殊的 HARQ反馈设计时, 宏 基站 Ml可在空口, 以广播方式或者单播方式, 向新版本 UE通知小区 Cml更改 的 UL子帧 (时隙) 配置, 而对于旧版本的 UE可不进行通知。
其中, 宏基站 Ml可向其服务的部分或全部 UE发送服务小区更新配置信 息, 该服务小区更新配置信息如下信息的一种或多种:
所调整小区 Cml资源的上行和 /或下行频点信息、 所调整小区 Cml 源的上 行和 /或下行带宽信息、调整小区 Cml资源后的空白(mute )子帧的上行和 /或下 行位置信息、 小区 Cml资源调整的激活时间信息。
对于 Pico基站可能配置非 TDD小区的情况, 宏基站 Ml对其下的新版本的 UE的空口通知方式有广播方式(通过系统广播消息)和单播方式(通过专用 信令消息)。 其中, 若使用专用信令通知 UE, 小区 Cm 々上下行 mute的信息可 在携带在多种下行的信令中传输, 例如寻呼消息, 连接建立消息, 连接重配置 消息, 连接重建立消息, 下行消息传输消息中。
507、 Pico基站 P1配置新 Pico小区 CP2和无线回程链路;
其中, Pico基站 P1可根据宏小区 Cml提供的资源, 以及相邻小区对宏小区
Cml的干扰状况,确定使用宏小区 Cml¾供的资源部署 Pico小区 CP2和无线回程链 路, 其中, 新部署 Pico小区 CP2可看成将小区的无线接入链路的资源从无调整 为有, 或者从一种配置变化为另一种配置,新配置无线回程链路可看成将无线 回程链路的资源从无调整为有或者或者从一种配置变化为另一种配置。
新部署 Pico小区 CP2的上下行子帧 (时隙) 配比:
Pico基站 P1可以根据宏小区 Cml提供上行资源的子帧数和 TDD小区配置模 式进行匹配, 得到满足 TDD小区配置模式的 Pico小区 CP2上下行子帧配比。 或 者, Pico基站 P1亦可根据 HARQ时隙和上下行调度的处理需要, 确定 Pico小区 CP2的上下行子帧 (时隙) 配比。
下面主要以将 Pico小区 CP2配置为 TDD小区(即 Pico基站 P1新部署一个 TDD 小区) 为例进行描述, 而将 Pico小区 CP2配置为非 TDD小区 (即灵活的上下行 配置) 的上下行配置的情况也类似。
对于灵活的上下行配置的情况下(即配置非 TDD小区), Pico小区 CP2的上 下行子帧的位置可由有效的 H ARQ时序来决定的。
此前, 基站间还可交互各自的硬件处理能力 (包括发射和接收能力), 或 者非完整的小区配置信息。对于基站可增加一个小区而没有频谱资源的小区配 置能力, 也可以通知给相邻基站。 该交互信息可在基站间接口建立时发送, 也 可在后续的接口信令中交互。
比如, 为了支持在 FDD UL频段上进行下行发送, 需要在该基站上增加一 个新的发射通道。 对于 6-b的场景, 还需要增加一个接收通道的配置。 如果宏 基站 Ml (资源提供基站)获知 Pico基站 P1具有新增发射通道的能力, 则宏基 站 Ml可以有针对性的向 Pico基站 P1发送消息, 向其提供 FDD UL频段资源。
Pico基站 P1上可以先配置部分小区 CP2信息 (尽管小区 CP2在未配置上下行 资源前处于未运行的去激活状态), 并和相邻基站 (包括宏基站 Ml和宏基站 M2 )进行交互, 其中, 基站间交互的小区 CP2的部分配置信息可包括如下信息 的一种或多种:
小区 CP2的物理层小区标识, 高层小区标识, 跟踪区码, PLMN标识等; 小区 CP2的工作模式为 TDD模式还是 FDD模式(可选的);
小区 CP2的状态 (未完全配置时为去激活状态)。
此外, 若基站间不交互基站的硬件处理能力, 则可提供资源的基站可向部 分或全部相邻基站发送 FDD UL资源提供信息, 而具有相应硬件处理能力的相 邻基站可对应的响应。
508、 Pico基站 P1向宏基站 Ml发送消息 ms512 (例如为, eNB配置更新响 应消息或小区激活响应消息或 eNB配置更新消息、 或其它消息);
其中, Pico基站在部署好新 Pico小区 CP2后, 可通过 eNB配置更新响应消息 或小区激活响应消息或 eNB配置更新消息(消息 ms512 ),通知宏基站 Ml新 Pico 小区 CP2的配置情况。
在实际应用中, Pico基站 P 1可在 eNB配置更新响应消息或小区激活响应消 息或 eNB配置更新消息 (消息 ms512 ) 中携带如下信息的一种或多种: 所 Pico 基站 PI所调整无线回程链路和 Pico小区 CP2无线接入链路资源的频点信息、 所 调整无线回程链路和 Pico小区 CP2无线接入链路资源的带宽信息、 所调整无线 回程链路和 Pico小区 CP2无线接入链路资源的时隙位置信息、 所调整无线回程 链路和 Pico 'J、区 CP2无线接入链路资源的子帧偏置信息、 上下行保护间隔的配 置信息。 进一步的, 消息中还可以携带: 所调整的无线链路资源的用途信息, 和 /或, 无线链路资源调整、 节能配置的激活时间信息。
509、 Pico基站 P1通知其服务的 UE小区配置变更;
在一种应用场景下, Pico基站 P1可通过系统消息或者专用信令, 向其服务 的部分或全部用户终端(例如可只向 R10等新版本 UE通知小区配置变更, 或向 所有 UE通知小区配置变更)发送服务小区更新配置信息, 该服务小区更新配 置信息可包括如下信息的一种或多种: 所调整无线回程链路和 Pico 'J、区 CP2资 源的上行和 /或下行频点信息、 所调整无线回程链路和 Pico小区 CP2资源的上行 和 /或下行带宽信息、 无线回程链路和 Pico小区 CP2资源调整的激活时间信息、 上下行保护间隔的配置信息等信息。
此外, Pico基站 P1亦可通过系统消息或专用信令, 向其服务的部分或全部 用户终端发送相邻小区配置更新信息,该相邻小区配置更新信息可包括如下信 息的一种或多种: 宏基站 M2所调整相邻小区 Cml资源的频点信息、 所调整相邻
小区 cml资源的带宽信息、所调整相邻小区 cml 源的时隙位置信息、所调整相 邻小区 cml 源的子帧偏置信息; 相邻小区 cml资源调整的激活时间信息、上下 行保护间隔的配置信息。
510、 宏基站 M2向宏基站 Ml发送消息 ms522 (例如为, eNB配置更新响应 消息或小区激活响应消息或 eNB配置更新消息、 或其它消息)。
宏基站 M2亦可通知其服务的 UE小区 CP2的相邻小区配置变更。
在一种应用场景下, 宏基站 Ml可通过系统消息或者专用信令, 向其服务 的部分或全部用户终端(例如可只向 R10等新版本 UE通知小区配置变更, 或向 所有 UE通知小区配置变更)发送服务小区更新配置信息, 该服务小区更新配 置信息如下信息的一种或多种: 所调整无线回程链路上行和 /或下行频点信息、 所调整无线回程链路资源的上行和 /或下行带宽信息、 无线回程链路资源调整 的激活时间信息等信息、 上下行保护间隔的配置信息。
