Description

为多个小区簇之间的緩沖区
配置时隙的方法和装置 技术领域
本发明涉及无线通信网络, 尤其涉及无线通信网络的时分双工 系统中配置上、 下行时间资源的方法和装置。 背景技术
时分双工 (TDD )是一种现代通信系统常用的双工方式, 在 TDD 方式的移动通信系统中,接收和发送使用同一频率栽波的不同时隙作为 信道的承载, 用时间来保证接收与发送信道的分离, 即保证接收和发送 之间不会冲突。 进一步的, 各个接收机使用不同的接收时隙, 接收对应 的发射机在对应的不同时隙发送的信号, 保证了各个接收机之间, 及各 个发射机之间不会产生冲突。
在 TDD系统中, 同一载频会产生上、 下行时隙配置不同的场景, 例如:
A. 在一个运营商内部的不同网络区域中, 由于上、 下行业务的分 布情况不同,所以为不同区域具有不同的上、下行资源的配置,也即上、 下行时隙的比例。 例如, 在写字楼比较集中的商务区域, 考虑到话音业 务较多, 上、 下行业务基本持平, 在此区域的上、 下行配置基本相同; 在住宅区, 考虑到该区域内一般居民下栽数据的需求比较大, 而上传数 据较少, 因此为下行时隙配置较多, 上行时隙配置较少。
B. 类似的, 不同的运营商在不同区域也会出现上述问题。 也即, 不同运营商分别运营各自的网络, 采取不同的策略, 因而对各自网络的 系统资源的上、 下行配置不同。
与此同时, 由于运行商通常只能得到颁定的少量频率资源, 因此受 频率数量所限, 这些运行商内部的网络区域可能共享着少量, 甚至一个 相同的载频(例如, 均为 700MHz的载频); 同时, 不同的运营商之间 也可能共享同一个载频资源。 在这种情况下, 当使用同一载频的相邻的
1
确 认 本 不同小区具有不同的上、 下行时隙配置时, 会产生簇间干扰。 即当其中 一个小区使用一个时隙传输上行链路信息, 而使用不同的上下行时隙配 置的另一个相邻小区使用同一时隙传输下行链路信息,那么两个小区之 间可能存在干扰。
具体的, 在同一时刻或同一时间段, 当位于一个小区内的移动终端 接收信息, 而位于相邻小区的另一个移动终端在相同载频发送信息, 且 该两个移动终端均位于小区边缘并相隔较近时,发送上行信号的移动终 端发出的信号可能会对抵达正在用相同载频接收下行信号的另一个移 动终端处, 对其接收相同载频的下行信号产生干扰。
此外, 两个相邻的载频之间, 考虑到邻频泄漏, 即一个载频的能量 不一定集中在中心频率, 该载频的能量会泄露到相邻载频, 因此使用该 频率的小区会与使用相邻载频的相邻小区之间产生簇间干扰, 例如, 一 个载频为 405MHz, 另一个载频为 400MHz, 在同一时刻或同一时间段, 当位于载频为 400MHz的一个小区内的移动终端接收信息,而位于栽频 为 405MHz的相邻小区的另一个移动终端在相同载频发送信息,且该两 个移动终端均位于小区边缘并相隔较近时, 以 405MHz载频发送上行信 号的移动终端发出的信号可能会对抵达正在用相邻载频接收下行信号 的另一个移动终端处, 对其接收相邻载频的下行信号产生干扰。
现有技术中, 为了解决上述问题, 在两个或多个使用不同的上、 下 行时隙配置的小区簇之间的交界区域中设置緩沖区域 ,该緩沖区域不设 置基站。 由于无基站覆盖, 则在该緩冲区域上的时隙均为保留, 也即牺 牲了緩冲区域中的时隙, 以保证一个小区中的移动终端的上行信号经过 緩冲区域的衰减, 不会对緩沖区域另一边的小区在同一时隙上的下行信 号造成干扰。
显然, 由于现有技术中该緩冲区域未设置基站, 因而会带来以下缺 点:
1. 在緩冲区域的用户无法得到通信服务, 用户体验很差;
2. 在緩冲区域内的传输容量为零, 而当緩沖区域较大时, 会造成 较大的通信容量损失。 发明内容
为了解决现有技术中, 无法充分利用緩冲区域的时间资源的问题, 本发明提出了对緩冲区域进行时间资源配置的方案, 具体如下: 緩冲区 域的基站获取与其相邻的多组小区簇分别对应的多个时间资源配置相 关信息, 而后根据该多个时间资源配置相关信息, 为本基站所辖的小区 确定上、 下行资源配置, 以使得其与所述多组小区簇之间不产生簇间干 扰。优选地, 当緩冲小区的多个使用相同或相邻载频,且具有不同的上、 下行时间资源配置的相邻的小区在与緩冲区域的一个或多个时间资源 相对应的时间资源的上、 下行时间资源配置一致时, 将緩冲区域的同一 个或多个时间资源也配置为与相邻的小区相同的上、 下行时隙; 当緩冲 区域的多个具有不同的上、下行时间资源配置方式的相邻的小区在与緩 冲区域的一个或多个时间资源相对应的时间资源的上、下行时间资源配 置方式不完全一致时, 优选地, 緩冲区域的基站从预先获取的相邻的小 些移动终端是否处于小区边缘区域进行进一步地确定。 更进一步, 即使 多个相邻小区的与緩沖区域的一个或多个时间资源相对应的时间资源 的上、 下行时间资源配置方式不完全一致, 但由于相邻小区未将对应的 时间资源分配给移动终端,或者分配的移动终端不处于与緩沖小区相邻 的小区边缘区域,则緩沖区域的基站仍可以将所述时间资源配置为上行 或下行时间资源。

根据本发明的第四方面,提供了一种一种在无线通信网络的与緩冲 小区相邻的小区簇的基站中用于辅助所述緩冲小区的基站配置上行和 / 或下行资源的辅助配置装置, 其中, 所述无线通信网络采用时分双工的 工作方式, 所述小区簇与緩沖小区采用相同或相邻载频, 该辅助配置装 置包括: 发送装置, 用于向所述緩沖区域的基站发送本基站所在的小区 簇的资源分配相关信息。

图 1为根据本发明的一个具体实施例的网络拓朴结构示意图。其中 簇边缘小区 2、 簇边缘小区 4和非簇边缘小区 6属于第二小区簇 (Cell Cluster ) CC1 , 第一小区簇 CC1中的所有小区用斜划线表示, 第一小区 簇 CC1 中所有小区的上、 下行配置相同, 且每个时隙的起始时间和终 止时间也相同, 是完全同步的。 此外, 因为位于簇中心的小区距离緩沖 小区较远, 因此通常不会对緩沖小区产生干扰。 其中, 簇边缘小区 2由 基站 B所辖。 簇边缘小区 3和簇边缘小区 5属于第二小区簇 CC2, 第二小区簇 CC2中的所有小区用竖线表示, 第二小区簇 CC2中所有小区的上、 下 行配置相同,且每个时隙的起始时间和终止时间也相同,是完全同步的。 因为位于簇中心的小区距离緩冲小区较远, 因此通常不会对緩冲小区产 生干扰。 此处为了便于说明, 仅示出簇边缘小区 3和簇边缘小区 5 , 而 省略了其他非边缘小区。 其中, 簇边缘小区 3由基站 C所辖。
緩冲小区 1位于第一小区簇 CC1和第二小区簇 CC2之间的緩冲区 域, 緩冲小区 1由基站 A所辖, 基站 A根据第一小区簇 CC1和第二小 区簇 CC2的上下行资源分配相关信息, 为緩冲小区 1进行上下行资源 的配置。 緩沖小区 1可以与一个或多个簇的簇边缘小区相邻, 在图 1中 为了便于说明, 仅显示緩沖小区 1 与第一小区簇 CC1 的簇边缘小区 2 和 4和第二小区簇 CC2的簇边缘小区 3和 5相邻, 进一步地, 因为第 一小区簇 CC1中的所有小区的上下行配置情形一致,且第二小区簇 CC2 中的所有小区的上下行配置情形一致, 以下, 为了便于说明, 以第一小 区簇 CC1 中的簇边缘小区 2为例, 代表第一小区簇 CC1进行说明, 以 第二小区簇 CC2中的簇边缘小区 3为例, 第二小区簇 CC2进行说明。
实际中, 在一种情况下, 第一小区簇 CC1和第二小区簇 CC2可以 由相同的运营商基于同一标准进行配置, 且第一小区簇 CC1 和第二小 区簇 CC2的每帧中对应的各时隙完全对齐, 但第一小区簇 CC1和第二 小区簇 CC2 的相对应的时隙的上、 下行配置方式不完全相同; 在另一 种情况下, 第一小区簇 CC1和第二小区簇 CC2可以由不同的运营商进 行配置, 因此, 可能采用不同的网络标准。 例如, 第一小区簇 CC1 釆 用基于 Wimax的 TDD网络,第二小区簇 CC2采用基于 LTE的 TDD网 络, 因此第一小区簇 CC1和第二小区簇 CC2的一帧中的各时隙不完全 对齐。 以下, 我们先针对上述第一种情形对本发明进行说明。
以图 2为例进行说明, 图 2为根据本发明的一个具体实施例的簇边 缘小区 2和簇边缘小区 3的时间资源的上、 下行配置的示意图。 此处第 一小区簇 CC1 (簇边缘小区 2 ) 和第二小区簇 CC2 (簇边缘小区 3 ) 的 每个相对应的帧中的时隙是对齐的。 在此, 时间资源指时隙, 但本领域 技术人员根据以下描述应能理解其他类型的时间资源也应能适用于本 发明。
下面以一个帧包含七个时隙为例进行说明,一帧中包含的时隙的数 目由所在网络的标准中所规定的帧格式所确定。 例如, 在 LTE的 TDD 网络中,一个 10ms的帧包括两个 5ms的子帧,每个子帧包括 7个时隙, 图 2中的緩冲小区 1的 7个时隙分别为 TS0至 TS6,此处为了便于说明, 省略了相邻时隙之间的保护间隔等, 仅示出上、 下行配置。 簇边缘小区 2的一帧中与緩沖小区 1 的各个时隙 TS0-TS6相对应的各时隙分别为 TS0,-TS6,, 而簇边缘小区 2的一帧中与緩沖小区 1各个时隙 TS0-TS6 相对应的的各时隙分别为 TS0"-TS6", 其中, 相对应的时隙在时间轴上 完全重叠。 若以 D表示下行时隙, U表示上行时隙, 如图 2所示, 作为 示例, 簇边缘小区 2的一帧中的各时隙 TS0,-TS6,为 D\D\D\U\U\D\U, 簇边缘小区 3的一帧中的各个时隙 TS0"-TS6"为 D\D\U\U\D\U\U, 且簇 边缘小区 2和 3中的上下行时隙在一段时间保持不变。

以下参照图 3并结合图 1和图 2对本发明第一实施例进行描述,其 中, 第一实施例针对基站 A获取的资源分配相关信息包括: 分别用于指 示第一小区簇 CC1和第二小区簇 CC2中各自配置的上、 下行时隙配置 信息的情形进行说明。
首先, 在步骤 S10中, 基站 A获取第一小区簇 CC1和第二小区簇 CC2分别对应的资源分配相关信息, 其中, 该资源分配信息分别包括第 一小区簇 CC1和第二小区簇 CC2的上、 下行时隙的配置信息。 对于一 个小区簇, 该小区簇内的所有小区的上、 下行时隙可以在该小区所在的 网络配置初期由运营商或基站预先配置好,也可以是根据网络需求由基 站动态调整, 也即, 将一个时隙分配给具体的某个移动终端是由基站动 态地确定, 而该时隙的上、 下行的通信方式是由基站预先配置好, 并且 在一定的周期内保持不变。一个小区簇中的所有小区中的基站都按照上 述已设置好的上、 下行时隙配置方式为每一帧的各个时隙进行配置。 例 如, 基站 B可以通过有线接口 (cable )或 IP网络等, 将簇边缘小区 2的上、 下行时隙的配置信息发送给基站 A。 同理, 基站 C可以通过 有线接口( cable )或 IP网络等,将其资源分配相关信息发送给基站 A。 作为示例, 簇边缘小区 2的上、 下行时隙的配置信息指示簇边缘小区 2 的一帧中的各时隙 TS0,-TS6,分别为 D\D\D\U\U\D\U,簇边缘小区 3的 上、 下行时隙的配置信息指示簇边缘小区 3 的一帧中的各时隙 TS0"-TS6"分别为 D\D\U\U\D\U\U。
在一个变化的实施例中, 基站 A 中保存有在前次的通信中已获取 的, 簇边缘小区 2和簇边缘小区 3的一帧的各个时隙的上、 下行配置信 息, 且簇边缘小区 2和簇边缘小区 3的时隙的上行、 下行配置从前次通 信到现在没有发生改变,则基站 A可以利用所保存的簇边缘小区 2和簇 边缘小区 3的上、 下行时隙的配置信息。
则在步骤 S11 中, 根据上、 下行时隙的配置信息, 基站 A确定在 第一小区簇 CC1和第二小区簇 CC2的与緩沖小区 1的各个时隙相对应 的时隙的配置方式是否一致。具体地,基站 A确定簇边缘小区 2和簇边 缘小区 3中与緩沖小区 1的每个时隙相对应的时隙是否均被簇边缘小区 2配置用于上行通信或均配置用于下行通信, 例如, 对于緩沖小区 1中 的时隙 TS1 , 在簇边缘小区 2中与之对应的时隙 TS1,和在簇边缘小区 3 中与之对应的时隙 TS1,,是否均被配置用于上行或下行通信, 也即上行 时隙或下行时隙。
在步骤 S12中,当基站 A确定在第一小区簇 CC1和第二小区簇 CC2 中与緩沖小区 1 中的一个或多个时隙相对应的时隙的配置方式相一致 时, 则基站 A与在第一小区簇 CC1和第二小区簇 CC2中配置方式相一 致地将该一个或多个时隙配置为緩沖小区 1的上行或下行时隙, 以使得 緩沖小区 1与第一小区簇 CC1、 第二小区簇 CC2之间不产生簇间干扰。
具体地, 基站 A确定簇边缘小区 2将与时隙 TS0和 TS1分别对应 的时隙 TS0'和 TS1, 配置为下行时隙 (D ) , 且簇边缘小区 3将与时隙 TS0和 TS1分别对应的时隙 TS0"和 TS1"也配置为下行时隙 (D ) ; 基 站 A确定簇边缘小区 2将与时隙 TS3和 TS6分别对应的 TS3'和 TS6' 配置为上行时隙 (U), 且基站 A确定簇边缘小区 3将与时隙 TS3和 TS6 分别对应的 TS3"和 TS6,,也配置为上行时隙 (U), 因此, 相应地, 基站 A 将 TS0, TS 1也配置为下行时隙, 将 TS3和 TS6也配置为上行时隙。 这 样, 在时隙 TS0和 TS1上, 簇边缘小区 2和簇边缘小区 3在上述时隙 均为下行时隙, 以使得緩冲小区 1与簇边缘小区 2和簇边缘小区 3之间 不会产生簇间干扰; 在时隙 TS3和 TS6上, 簇边缘小区 2和簇边缘小 区 3在上述时隙均为上行时隙, 以使得緩沖小区 1与簇边缘小区 2和簇 边缘小区 3之间不会产生簇间干扰。 而簇边缘小区 2和簇边缘小区 3对 与时隙 TS2、 TS4和 TS5所分别对应的时隙的配置情形不一致, 因此, 基站 A将緩冲小区 1的时隙 TS2, TS4和 TS5分配为保留, 不分配给任 何移动终端, 因此, 在这些时隙, 緩冲小区 1与簇边缘小区 2和簇边缘 小区 3之间也不会因这些时隙的上、下行时隙配置不一致而产生簇间干 扰。
第二实施例
图 4显示了根据本发明的另一个实施例的基站 A中用于为緩沖小区 1配置上、 下行时隙的方法流程图。 其中, 第二实施例针对基站 A获取 的资源分配相关信息包括用于指示干扰相关信息的情形进行说明, 因为 考虑到干扰相关信息, 如图 2所示, 因为与緩冲小区 1相邻的簇边缘小 区 2和簇边缘小区 3会与緩沖小区 1之间存在潜在干扰, 因此, 以下我 们以簇边缘小区 2和簇边缘小区 3为例进行说明。
以下参照图 4并结合图 1和图 2对本发明的一个具体实施例进行描 述。
在步骤 S 10,中, 基站 A获取簇边缘小区 2和簇边缘小区 3分别对 应的资源分配相关信息, 其中, 资源分配相关信息包括干扰相关信息。 其中, 干扰相关信息包括以下各项中的任一项或任多项:
i) 用于指示簇边缘小区 2的与緩沖小区 1的各个时隙相对应的时隙 上,簇边缘小区 2与緩冲小区 1之间是否产生潜在簇间干扰的信息以及 簇边缘小区 3的与緩冲小区 1的各个时隙相对应的时隙上,簇边缘小区 3与緩冲小区 1之间是否产生潜在簇间干扰的信息, 例如, 簇边缘小区 2的与緩冲小区 1的时隙 TS2相对应的时隙包括:在时间轴上与 TS2时 隙至少部分重叠的簇边缘小区 2中的时隙,如 TS2,, 因为在本实施例中, 緩冲小区 1与簇边缘小区 2和簇边缘小区 3中的每一帧的时隙是完全对 齐的,因此簇边缘小区 2中与緩冲小区的时隙 TS0-TS6相对应的时隙分 别为 TS0,-TS6,,簇边缘小区 3中与緩沖小区的时隙 TS0-TS6相对应的 时隙分别为 TS0"-TS6"。
其中簇边缘小区与緩沖小区 1之间会产生潜在簇间干扰的情形包括 该簇边缘小区将与緩冲小区 1 的一个或多个时隙相对应的时隙分配给 移动终端, 且该移动终端位于簇边缘小区的小区边缘, 若该移动终端使 用的是上行时隙,则该移动终端的上行通信会对在緩冲小区 1内的使用 相对应的时隙进行下行通信的移动终端造成干扰; 若该移动终端使用的 是下行时隙,则该移动终端的下行通信会受到在緩沖小区 1内的使用相 对应的时隙进行上行通信的移动终端的干扰。
相应地,簇边缘小区与緩沖小区 1之间不会产生潜在簇间干扰的情 形包括:簇边缘小区未将簇边缘小区的与緩冲小区 1的一个或多个时隙 相对应的时隙分配给移动终端; 或者, 分配该时隙的移动终端位于簇边 缘小区的小区内部, 距离緩冲小区 1较远。
ϋ ) 用于指示簇边缘小区 2和簇边缘小区 3是否已经将簇边缘小区 中的与緩冲小区 1的各个时隙相对应的时隙分配给移动终端的信息, 当 该信息指示与緩冲小区 1 的一个或多个时隙相对应的时隙未分配给移 动终端时, 则基站 Α可以确定在该一个或多个时隙上,该簇边缘小区与 緩沖小区 1之间不会产生潜在簇间干扰。
Hi )用于指示相应的簇边缘小区的在与緩沖小区 1的一个或多个时 隙相对应的时隙上所分配的移动终端的位置信息, 当该信息指示使用緩 冲小区 1 的一个或多个时隙相对应的时隙的簇边缘小区的移动终端位 于潜在干扰区域时, 若该移动终端位于潜在干扰区域时, 如该移动终端 使用的是上行时隙, 则该移动终端的上行通信会对在緩冲小区 1内的使 用相对应的时隙进行下行通信的移动终端造成干扰;若该移动终端使用 的是下行时隙,则该移动终端的下行通信会受到在緩冲小区 1内的使用 相对应的时隙进行上行通信的移动终端的干扰,则基站 A可以确定在该 一个或多个时隙上, 该簇边缘小区与緩沖小区之间会产生潜在簇间干 扰。
此外, 当考虑到簇边缘小区中存在中继站的情形时, 在簇边缘小区 的边缘的移动终端可以通过中继站与基站进行通信, 因此不需要使用很 大的发射功率, 此时该移动终端虽然处于簇边缘小区的边缘, 但是该移 动终端的上行信号并不会对緩冲小区 1产生潜在簇间干扰。 因此, 当存 在中继站的情形时,位置相关信息中的潜在干扰区域的位置的划分与不 存在中继站时的潜在干扰区域的位置划分可能存在不同。 因此, 存在中 继站时,将簇边缘小区中与緩沖小区 1之间会产生潜在簇间干扰的移动 终端的位置定义为潜在干扰区域。
干扰相关信息不仅仅局限于上述的几种确定标准,本领域一般技 术人员应能根据实际网络的情况,确定簇边缘小区中移动终端是否会与 緩沖小区产生潜在簇间干扰的其他情况。
具体地, 基站 B可以通过有线接口 (cable )或 IP网络等, 将干 扰相关信息发送给基站 。 同理, 基站 C可以通过有线接口 (cable ) 或 IP网络等, 将干扰相关信息发送给基站 A。 其他的干扰相关信息的 发送方式也是可行的, 并都应处于本发明及其权利要求的保护范围之 内。
在步骤 Si r中, 基站 A根据获取的干扰相关信息来确定簇边缘小 区 2和簇边缘小区 3的与緩冲小区 1的各个时隙相对应的时隙上是否会 间资仅有一种配置方式。
具体地, 当基站 A在步骤 S10,中获取的干扰信息为用于指示在緩 冲小区 1的各个时隙相对应的时隙上,簇边缘小区 2与緩沖小区 1之间 是否产生潜在簇间干扰的信息以及簇边缘小区 3与緩冲小区 1之间是否 产生潜在簇间千扰的信息,则根据该干扰信息指示,基站 A可以确定簇 边缘小区 2和簇边缘小区 3在与緩冲小区 1的各个时隙相对应的时隙是 否会与緩冲小区之间产生潜在簇间干扰。
例如, 来自簇边缘小区 2的干扰相关信息指示在时隙 TS0,、 TS4, 和 TS5,上,簇边缘小区 2会与緩沖小区 1之间产生潜在簇间干扰,且时 隙 TS0'配置为下行时隙, 时隙 TS4'配置为上行时隙, 时隙 TS5'配置为 下行时隙; 来自簇边缘小区 3的干扰相关信息指示在时隙 TS0"和 TS4" 和 TS6"上, 簇边缘小区 3会与緩冲小区 1之间产生潜在簇间干扰, 且 时隙 TS0"配置为下行时隙, 时隙 TS4"配置为下行时隙, 时隙 TS6"配置 为上行时隙。
当基站 A确定簇边缘小区 2和簇边缘小区 3在与緩冲小区 1的一个 或多个时隙相对应的时隙上与緩沖小区 1之间不产生潜在簇间干扰,或 产生潜在簇间干扰所对应的时隙仅有一种上、 下行时隙配置方式时, 则 在步骤 S12,中, 基站 A将緩沖小区 1 的该一个或多个时隙相应地配置 为緩冲小区 1的上行或下行时隙。
对于簇边缘小区 2和簇边缘小区 3与緩沖小区 1之间均不会产生潜 在簇间干扰的一个或多个时隙, 包括 TS1、 TS2和 TS3 , 基站 A可以将 上述时隙配置为上行时隙或下行时隙。 优选地, 如果对于一个时隙在簇 边缘小区 2和簇边缘小区 3的上、 下行时隙配置情形一致, 同为上行时 隙或同为下行时隙时, 则在步骤 S12,中, 基站 A将该时隙配置为与簇 边缘小区 2和簇边缘小区 3相一致的上、 下行时隙配置方式, 也为上行 时隙或下行时隙。 例如对于 TS1 , 基站 A也将其配置为下行时隙; 而对 于一个时隙, 其在簇边缘小区 2和簇边缘小区 3的上、 下行时隙配置情 形不一致时,基站 A可以按照一定的策略将该时隙配置为上行或下行时 隙, 例如将 TS2配置为上行或下行时隙。其中一定的策略包括随机配置 或者考虑緩沖小区 1的上、 下行配置均衡, 此为本领域技术人员应能理 解的, 因此在此不予赘述。
对存在潜在干 ·ί尤的一个或多个时隙, 例如 TS0、 TS4、 TS5和 TS6 中的每一个时隙,通过对各个相邻的簇边缘小区的与緩冲小区 1的时隙 相对应的时隙的上、 下行配置进行比较, 来判断是否会产生簇间干扰。
具体地, 对于时隙 TS0, 在簇边缘小区 2中的 TS0,是下行时隙, 且 在 TSO,上,簇边缘小区 2会与緩冲小区 1之间产生潜在簇间干扰,在簇 边缘小区 3中的 TS0"也是下行时隙, 且在 TS0"上, 簇边缘小区 3会与 緩沖小区 1之间产生潜在簇间干扰, 因为会产生潜在簇间干扰的簇边缘 小区 2和 3的上、 下行时隙配置方式只有一种, 同为下行时隙, 因此, 基站 A将緩沖小区 1的时隙 TS0也配置为与在簇边缘小区 2和簇边缘 小区 3的类型一致的上、下行时隙配置方式,也即,也配置为下行时隙。
对于时隙 TS4,由于在簇边缘小区 2中时隙 TS4,被配置为上行时隙, 且在该上行时隙上与緩冲小区 1之间会产生潜在簇间干扰,在簇边缘小 区 3中时隙 TS4"配置为下行时隙, 且在该时隙 TS4"上, 簇边缘小区 3 与緩冲小区 1之间会产生潜在簇间干扰。 因为在簇边缘小区 2和簇边缘 小区 3中, 与时隙 TS4相对应的时隙的上、 下行时隙配置方式不同, 因 此基站 A将该时隙 TS4设为保留(Reserved ) , 也即不分配用于上行或 下行通信。
对于时隙 TS5 ,虽然簇边缘小区 2和簇边缘小区 3对于时隙 TS5的 相应的时隙的上、 下行时隙配置方式不一致, 但是仅有簇边缘小区 2中 的与时隙 TS5相对应的下行时隙 TS5,上,簇边缘小区 2会与緩沖小区 1 之间产生潜在簇间干扰,而在簇边缘小区 3中的与时隙 TS5相对应的上 行时隙 TS5"上, 簇边缘小区 3不会与緩沖小区 1之间产生潜在簇间干 扰, 因此, 基站 A将时隙 TS5配置为与緩沖小区 1之间会产生潜在簇 间干扰的簇边缘小区 2所采用的上、下行时隙配置方式相一致的下行时 隙;
对于时隙 TS6, 仅有簇边缘小区 3 中的与 TS6相对应的上行时隙 TS6,上, 簇边缘小区 3会与緩冲小区 1之间产生潜在簇间干扰, 而在簇 边缘小区 2中的 TS6相对应的上行时隙 TS6"上, 簇边缘小区 2不会与 緩冲小区 1之间产生潜在簇间干扰, 因此, 基站 A将时隙 TS6配置为 与会与緩沖小区 1之间产生潜在簇间干扰的簇边缘小区 3所采用的上、 下行时隙配置方式相一致的上、 下行时隙配置方式, 也即, 基站 A将 TS6配置为上^"时隙。
在一个变化的实施例中,緩冲小区 1与至少两个小区簇的多个簇边 缘小区相邻, 例如, 緩冲小区与同属于一个小区簇的簇边缘小区 2和 4 相邻, 与同属于另一个小区簇的簇边缘小区 3和 5相邻, 甚者还与又一 个小区簇中的簇边缘小区相邻(图中未示出) 。 在同一个小区簇内, 所 有的小区的上、 下行时隙配置方式都是一致的, 即同一个时隙在同一个 小区簇内的不同小区中均配置为上行时隙或均配置为下行时隙, 但是, 对于一个具体的时隙, 同一个小区簇内的不同小区的干扰情况未必一 致。例如,对于时隙 TS0, 在同一个小区簇内的簇边缘小区 2在时隙 TS0 所对应的下行时隙 TS0,上,簇边缘小区 2会与緩沖小区 1之间产生潜在 簇间干扰, 而簇边缘小区 4在时隙 TS0所对应的下行时隙上,簇边缘小 区 4不会与緩冲小区 1之间产生潜在簇间干扰。 因此,基站 A只需考虑 会与緩沖小区 1之间产生潜在簇间干扰的簇边缘小区 2。 此外, 只要会 与緩冲小区 1之间产生潜在簇间干扰的簇边缘小区使用的是同一种上、 下行时隙配置方式, 即同为上行时隙或同为下行时隙,基站 A就可以为 缓冲小区 1配置为与会与緩冲小区 1之间产生潜在簇间干扰的小区上、 下行时隙配置方式相一致的时隙。
在另一个变化的实施例中, 当基站 A在步骤 S10,中获取的干扰信 息为用于指示簇边缘小区 2和簇边缘小区 3是否已经将与緩沖小区 1的 一个或多个时隙相对应的时隙分配给移动终端的信息, 例如,基站 B将 时隙 TS3,未分配给移动终端的信息通过有线接口 (cable ) 或 IP 网络 等发送给基站 A, 则在步骤 S i r中,基站 A根据簇边缘小区 2未将与 时隙 TS3相对应的时隙 TS3,分配给移动终端的信息,确定在该时隙 TS3 上, 簇边缘小区 2不会与緩沖小区 1之间产生潜在簇间干扰。
在另一个变化的实施例中, 参见图 2, 基站 A在步骤 S10,中获取的 干扰信息为用于指示簇边缘小区 2和簇边缘小区 3在与緩冲小区 1的一 个或多个时隙相对应的时隙上分配的移动终端的位置信息。 例如, 当该 位置信息指示基站 B将时隙 TS4,分配给移动终端, 且该移动终端位于 簇边缘小区 2的会与缓沖小区 1之间产生潜在簇间干扰的区域的时,基 站 B通过有线接口 (cable ) 或 IP网络等将该位置相关信息发送给基 站 A, 则在步骤 Si r中,基站 A根据分配时隙 TS4'的移动终端的位置 相关信息, 确定与时隙 TS4,相对应的时隙 TS4上簇边缘小区 2会与緩 沖小区 1之间产生潜在簇间干扰。
第三实施例
第三实施例为第一实施例和第二实施例的结合的一种优选的实施 方式。
参照图 2、 3和 4进行说明。 首先, 基站 A获取簇边缘小区 2和簇 边缘小区 3分别对应的资源分配相关信息,其中资源分配相关信息包括 上、 下行时隙的配置信息和干扰相关信息, 其中, 配置信息和干扰信息 分别如上述第一实施例和第二实施例所述。
然后基站 A根据上、下行时隙的配置信息,按照第一实施例的步骤
S10和步骤 S1 1进行操作, 在步骤 S12中, 当基站 A确定第一小区簇 CC1和第二小区簇 CC2的与緩冲小区 1 的一个或多个时隙相对应的时 隙的配置方式一致时,则基站 A与在第一小区簇 CC1和第二小区簇 CC2 中配置方式相一致地将该一个或多个时隙配置为緩冲小区 1 的上行或 下行时隙, 以使得緩沖小区 1与第一小区簇 CC1、 第二小区簇 CC2之 间不产生簇间干 ·ί尤。
当基站 Α确定第一小区簇 CC1和第二小区簇 CC2中的与緩冲小区 1中的一个或多个时隙相对应的时隙的配置方式不一致时, 则基站 A进 一步根据干扰信息, 对在簇边缘小区 2和簇边缘小区 3中上、 下行配置 方式不一致的时隙利用第二实施例中的步骤进行进一步的处理,本领域 技术人员应能理解, 在此不予赘述。
在一个变化的实施例中, 即使对于与时隙 TS4相对应的时隙上, 当 簇边缘小区 2和簇边缘小区 3均会与緩冲小区 1之间产生潜在簇间干 扰, 且簇边缘小区 2和簇边缘小区 3所设置的上、 下行时隙的配置方式 不一致时, 例如簇边缘小区 2将 TS4相对应的时隙 TS4,设置为上行时 隙, 簇边缘小区 3将 TS4相对应的时隙 TS4"设置为下行时隙, 基站 A 仍可以将该时隙 TS4分配给在緩冲小区 1内的处于非潜在干扰区域内的 移动终端作为上行时隙, 因为分配的移动终端位于非潜在干扰区域, 因 此, 该移动终端的上行通信不会干扰簇边缘小 3 的以时隙 TS4"进行下 行通信的移动终端,且緩冲小区 1内的移动终端在时隙 TS4进行上行通 信,簇边缘小区 2内的移动终端在时隙 TS4,也采用上行通信, 因此緩冲 小区 1与簇边缘小区 2之间也不会产生簇间干扰。
在一个变化的实施例中, 緩冲区域包括多个其他緩冲小区, 緩沖区 域中的多个緩冲小区之间的上、 下行时隙的配置方式可以不完全相同。 因此, 当緩冲小区 1的上、 下行时隙的配置方式确定以后, 基站 A可以 将其上、 下行时隙的配置相关信息和 /或干扰相关信息通知緩冲区域的 其他緩沖小区。
相应地, 与缓冲小区 1相邻的其他緩沖小区接收到来自緩沖小区 1 的上、 下行时隙的配置相关信息和 /或干扰相关信息后, 其他緩沖小区 也将緩冲小区 1看作为一个簇边缘小区, 并按照本说明书前述的方法为 该其他緩冲小区配置上行或下行时隙, 在此不予赘述。
以上为对第一小区簇 CC1和第二小区簇 CC2的时隙与緩沖小区 1 完全对齐的情形进行具体描述, 当第一小区簇 CC1、 第二小区簇 CC2 与緩冲小区 1的时隙不完全对齐或不完全同步时,上文描述的技术方案 也完全适用。
具体地, 图 5为根据本发明的另一个具体实施例的簇边缘小区 2和 簇边缘小区 3的上、 下行时隙配置的示意图。 其中, 簇边缘小区 2的一 帧中的各个时隙与緩冲小区 1的一帧中的各个时隙没有完全对齐, 而簇 边缘小区 3的一帧中的各个时隙与緩沖小区 1的的一帧中的各个时隙对 齐。每个与緩冲小区 1相邻的簇边缘小区与緩沖小区 1的时隙可以均不 对齐, 或者其中一个或多个相邻的簇边缘小区与緩沖小区 1对齐。
基站 A获取了簇边缘小区 2和簇边缘小区 3的各自的帧格式的相关 信息, 其中, 包括簇边缘小区 2和簇边缘小区 3各自的一帧中的每个时 隙的起始时间和终止时间。 因此,基站 A可以根据簇边缘小区 2和簇边 缘小区 3的一帧中的每个时隙的起始时间和终止时间,判断出其与緩沖 小区 1的各个时隙之间的对应关系, 其中, 时间上至少部分重叠的时隙 为相对应的时隙。
以 TS1为例, 簇边缘小区 2中的与緩冲小区 1的时隙 TS1相对应 的时隙为 TS0,和 TS1 ', 簇边缘小区 3中的与緩冲小区 1的时隙 TS1相 对应的时隙为 TS1"。
则对于第一实施例的一个变化例中, 在步骤 Si r中, 基站 A确定 簇边缘小区 2将与緩沖小区 1的时隙 TS0相对应的时隙 TS0,、 TS1 '均 配置为下行时隙,且簇边缘小区 3将与緩冲小区 1的时隙 TS0相应的时 隙 TS0"配置为下行时隙。 因此, 相应地, 在步骤 S12,中, 基站 A将緩 冲小区 1 中的时隙 TS0也配置为下行时隙。 这样, 在时隙 TS0上, 緩 沖小区 1、 簇边缘小区 2和 3在上述时隙均为下行时隙, 以使得緩沖小 区 1与簇边缘小区 2和簇边缘小区 3之间不会产生簇间干扰。
仍参照图 5, 对本发明的第二实施例的一个变化例进行筒要说明如 下:
在步骤 S 10,中,基站 A获取的干扰相关信息包括: 簇边缘小区 2的 与时隙 TS4相对应的时隙 TS3,上, 簇边缘小区 2会与緩冲小区 1之间 产生潜在簇间干扰,簇边缘小区 3的与时隙 TS4相对应的时隙 TS4"上, 簇边缘小区 3会与緩沖小区 1之间产生潜在簇间干扰。
因此, 在步骤 S i r中, 基站 A确定: 对于时隙 TS4, 在簇边缘小区 2中与时隙 TS4相对应的时隙 TS2,配置为上行时隙, 且在时隙 TS2,上, 簇边缘小区 2不会与緩冲小区 1之间产生潜在簇间干扰,在簇边缘小区 2中与时隙 TS4相对应的时隙 TS3,配置为下行时隙, 且在时隙 TS3,上, 簇边缘小区 2会与緩冲小区 1之间产生潜在簇间干扰, 在簇边缘小区 3 中与时隙 TS4相对应的时隙 TS4"被配置为下行时隙, 且在该时隙 TS4" 上, 簇边缘小区 3与緩冲小区 1之间会产生潜在簇间干扰。
因为在簇边缘小区 2和簇边缘小区 3中,会与緩沖小区 1之间产生 潜在簇间干扰的 TS4相对应的时隙 TS3,和 TS4"均配置为下行时隙, 因 此基站 A在步骤 S12,中, 将时隙 TS4配置为与会与緩沖小区 1之间产 生潜在簇间干扰的上、 下行时隙配置方式一致的上、 下行时隙配置, 也 即, 基站 A将 TS4配置为下行时隙。
在某些情况下, 例如上、 下行业务分布发生变化等情况下, 簇边缘 小区 2和 /或簇边缘小区 3会动态地改变其上下行时隙配置, 并生成新 的资源分配相关信息。 此时, 緩冲小区 1的基站 A将重复以上步骤, 即 根据簇边缘小区 2和 /或簇边缘小区 3的更新的资源分配相关信息, 重 新确定本緩沖小区的时隙配置方案。
以上为从緩冲小区 1的基站 A的角度对本发明进行描述,以下将从 与緩冲小区 1相邻的小区簇的基站的角度对本发明进行描述。
图 6 示出了根据本发明的第二方面的在无线通信网络的与緩沖小 区 1相邻的小区簇的基站中用于辅助緩冲小区 1的基站 A配置上、下行 时隙的方法流程图。
在步骤 S20中, 对属于与緩沖小区 1相邻的小区簇, 以第一小区簇 CC1为例, 第一小区簇 CC1中的非簇边缘小区 6中的基站 D根据用于 指示第一小区簇 CC1 中与緩沖小区 1相邻的簇边缘小区是否已经将簇 边缘小区的一个或多个时隙相对应的时隙分配给移动终端的信息和 /或 用于指示簇边缘小区中分配有緩冲小区 1 的一个或多个时隙相对应的 时隙的移动终端的位置信息来生成干扰相关信息, 其中, 干扰相关信息 用于指示与緩冲小区 1的一个或多个时隙相对应的时隙上,簇边缘小区 与緩冲小区 1之间是否会产生潜在簇间干扰的信息。 以下以与緩沖小区 1相邻的簇边缘小区为簇边缘小区 2为例进行说明。基站 D可以通过有 线接口 (cable )或 IP网络等与基站 B进行通信。 上面虽以非簇边缘 小区 6 中的基站 D为例进行说明, 但本领域技术人员应能理解上述步 骤也可适用于小区簇内的簇边缘小区。
具体地, 基站 D可以通过有线接口 (cable ) 或 IP网络等, 从基 站 B处获取簇边缘小区 2的资源分配相关信息。 获取的信息为用于指 示簇边缘小区 2是否已经将与緩沖小区 1的一个或多个时隙相对应的时 隙分配给移动终端的信息。 例如, 基站 B将与緩冲小区 1 的时隙 TS3 相对应的时隙 TS3,未分配给移动终端, 则基站 D根据上述信息, 生成 干扰相关信息, 包括在时隙 TS3相对应的时隙 TS3,上, 簇边缘小区 2 不会与緩冲小区 1之间产生潜在簇间干扰。
在一个变化的实施例中, 参见图 2, 当基站 D获取的信息为用于指 示簇边缘小区 2中与緩冲小区 1的一个或多个时隙相对应的时隙上分配 的移动终端的位置信息。 例如, 该位置信息指示基站 B将时隙 TS4'分 配给移动终端, 且该移动终端位于簇边缘小区 2的边缘会与緩冲小区 1 之间产生潜在簇间干扰的区域时,则基站 D生成干扰相关信息, 包括在 与时隙 TS4相对应的时隙 TS4,上该簇边缘小区 2会与緩冲小区 1之间 产生潜在簇间干扰。
在步骤 S21中,基站 D向基站 A发送基站 D所在的第一小区簇 CC1 的资源分配相关信息, 其中, 资源分配相关信息包括簇边缘小区 1与緩 沖小区 1之间的干扰相关信息。
基站 D可以在基站 B预先设定好每个帧的各个时隙的上、 下行时 隙配置信息, 并已将各个时隙预分配给或确定未分配给移动终端后, 将 干扰相关信息发送给基站 A。
在一个变化的实施例中, 步骤 S20可以省略, 则在步骤 S21中, 基 站 D直接向基站 A发送簇边缘小区 2的资源分配相关信息, 其中, 资 源分配相关信息包括簇边缘小区 2与緩冲小区 1之间的干扰相关信息。 其中, 干扰相关信息包括以下任一项或任多项:
- 用于指示第一小区簇 CC1 中与緩沖小区 1相邻的簇边缘小区 2 是否已经将与緩冲小区 1 的一个或多个时隙相对应的时隙分配给移动 终端的信息;
- 用于指示第一小区簇 CC1的簇边缘小区 2在与緩冲小区 1的一 个或多个时隙相对应的时隙上所分配的移动终端的位置信息。
在另一个变化的实施例中, 在步骤 S21 中, 基站 D向基站 A发送 簇边缘小区 2的资源分配相关信息, 其中, 资源分配相关信息包括上、 下行时隙配置信息。
在另一个变化的实施例中, 在步骤 S21 中, 基站 D向基站 A发送 簇边缘小区 2的资源分配相关信息, 其中, 资源分配相关信息包括上、 下行时隙配置信息和干扰相关信息。
在某些情况下, 例如上、 下行业务分布发生变化等情况下, 基站 B 会动态地改变其上、 下行时隙配置。 此时, 基站 D将重复以上步骤, 将 新的资源分配相关信息提供给基站 A。 基站 D所完成的上述步骤 S20与 S21完全可以由第一小区簇 CC1 内的任意一个小区的基站所完成, 只要第一小区簇 CC1 内的基站之间 可以相互通信。 当上述步骤由簇边缘小区 2 的基站所执行时, 在步驟 S20中, 基站 B可以直接对本基站获取的资源分配相关信息进行操作。
第四实施例
图 7是根据本发明一个具体实施例, 基站 A中用于为緩冲小区 1 配置上、 下行时隙的第一配置装置 10的装置框图。 图 7所示的第一配 置装置 10位于图 1所示的基站 A中。 第一配置装置 10包括获取装置 100, 第一确定装置 101, 其中, 第一确定装置 101还包括第二确定装置 1010和第二配置装置 1011。
以下参照图 7并结合图 1和图 2对本发明第四实施例进行描述,其 中,第四实施例针对基站 A获取的资源分配相关信息包括用于指示为第 一小区簇 CC1和第二小区簇 CC2各自配置的上、 下行时隙的配置信息 的情形进行说明。
首先, 获取装置 100获取第一小区簇 CC1和第二小区簇 CC2分别 对应的资源分配相关信息, 其中, 该资源分配信息分别包括第一小区簇 CC1和第二小区簇 CC2的上、 下行时隙的配置信息。 对于一个小区簇, 该小区簇内的所有小区的上、下行时隙配置可以在该小区所在的网络配 置初期由运营商预先配置好的, 也可以是根据网络需求由基站动态调 整,也即,将一个时隙分配给具体的某个移动终端是由基站动态地确定, 而该时隙的上、 下行的通信方式是由基站预先配置好, 并且在一定的周 期内保持不变。一个小区簇中的所有小区中的基站都按照上述已设置好 的上、 下行时隙的配置方式为每一帧的各个时隙进行配置。 例如, 基站 B可以通过有线接口 (cable ) 或 IP网络等, 将簇边缘小区 2的上、 下行时隙的配置信息发送给获取装置 100。 同理, 基站 C 可以通过有 线接口 (cable )或 IP网络等, 将资源分配相关信息发送给缓沖小区 1 的获取装置 100。 作为示例, 来自基站 B的上、 下行时隙的配置信息指 示簇边缘小区 2的一帧中各时隙 TS0,-TS6,分别为 D\D\D\U\U\D\U, 来自 基站 C的上、 下行时隙的配置信息指示簇边缘小区 3 的一帧中各时隙 TS0"-TS6"分别为 D\D\U\U\D\U\U。
在一个变化的实施例中,获取装置 100保存有在前次的通信中获取 的, 簇边缘小区 2和簇边缘小区 3的一帧的各个时隙的上、 下行配置信 息, 且簇边缘小区 2和簇边缘小区 3的时隙的上行、 下行配置在从前次 通信到现在没有发生改变,则获取装置 100可以利用所保存的簇边缘小 区 2和簇边缘小区 3的上、 下行时隙的配置信息。
第一确定装置 101 中的第二确定装置 1010根据上、 下行时隙的配 置信息, 确定在第一小区簇 CC1和第二小区簇 CC2中的与緩沖小区 1 的各个时隙相对应的时隙的配置方式是否一致。 具体地, 第二确定装置 1010确定簇边缘小区 2和簇边缘小区 3中与緩冲小区 1中的每一个时隙 相对应的时隙是否均被配置用于上行通信或均配置用于下行通信, 例 如,对于緩沖小区中的时隙 TS 1,在簇边缘' j、区 2中与之对应的时隙 TS 1, 和在簇边缘小区 3中与之对应的时隙 TS1 "是否均被配置用于上行或下 行通信, 也即上行时隙或下行时隙。
当第二确定装置 1010确定在第一小区簇 CC1和第二小区簇 CC2中 与緩冲小区 1中的一个或多个时隙相对应的时隙的配置方式相一致时, 则第二配置装置 101 1与在第一小区簇 CC1和第二小区簇 CC2中配置方 式相一致地将该一个或多个时隙配置为緩沖小区 1的上行或下行时隙, 以使得緩冲小区 1与第一小区簇 CC1、 第二小区簇 CC2之间不产生簇 间干扰。
具体地,第二确定装置 1010确定簇边缘小区 2将与时隙 TS0和 TS1 分别对应的时隙 TS0,和 TS1, 配置为下行时隙 (D ) , 且簇边缘小区 3 将与时隙 TS0和 TS1分别对应的时隙 TS0"和 TS1"也配置为下行时隙 ( D ) ; 第二确定装置 1010确定簇边缘小区 2将与时隙 TS3和 TS6分 别对应的 TS3,和 TS6,配置为上行时隙 (U), 且第二确定装置 1010确定 簇边缘小区 3将与时隙 TS3和 TS6分别对应的 TS3"和 TS6,也配置为上 行时隙 (U), 因此, 相应地, 第二配置装置 101 1将 TS0,TS1也配置为下 行时隙, 将 TS3和 TS6也配置为上行时隙。 这样, 在时隙 TS0和 TS1 上, 簇边缘小区 2和簇边缘小区 3在上述时隙均为下行时隙, 以使得緩 沖小区 1与簇边缘小区 2和簇边缘小区 3之间不会产生簇间干扰;在时 隙 TS3和 TS6上, 簇边缘小区 2和簇边缘小区 3在上述时隙均为上行 时隙, 以使得缓冲小区 1与簇边缘小区 2和簇边缘小区 3之间不会产生 簇间干扰。 而簇边缘小区 2和簇边缘小区 3对时隙 TS2、 TS4和 TS5所 分别对应的时隙的配置情形不一致, 因此, 第二配置装置 1011将緩冲 小区 1的时隙 TS2, TS4和 TS5分配为保留, 不分配给任何移动终端, 因此, 在这些时隙, 緩沖小区 1与簇边缘小区 2和簇边缘小区 3之间也 不会因这些时隙的上、 下行时隙配置不一致而产生簇间干扰。
第五实施例
图 8是根据本发明一个具体实施例, 基站 A中用于为緩沖小区 1 配置上、 下行时隙的第一配置装置 10,的装置框图。 图 8所示的第一配 置装置 10,位于以图 1所示的基站 A中。 第一配置装置 10,包括获取装 置 100,, 第一确定装置 101,, 其中, 第一确定装置 101,还包括第三确定 装置 1010,和第三配置装置 1011,。
以下参照图 8并结合图 1和图 2对本发明的一个具体实施例进行描 述。
获取装置 100,获取簇边缘小区 2和簇边缘小区 3分别对应的资源分 配相关信息, 其中, 资源分配相关信息包括干扰相关信息。 其中, 干扰 相关信息包括以下各项中的任一项或任多项:
i) 用于指示簇边缘小区 2的与緩冲小区 1的各个时隙相对应的时隙 上,簇边缘小区 2与緩冲小区 1之间是否产生潜在簇间千扰的信息以及 簇边缘小区 3的与緩沖小区 1的各个时隙相对应的时隙上,簇边缘小区 3与緩冲小区 1之间是否产生潜在簇间干扰的信息, 例如, 簇边缘小区 2的与緩冲小区 1的时隙 TS2相对应的时隙包括:在时间轴上与 TS2时 隙至少部分重叠的簇边缘小区 2中的时隙,如 TS2,, 因为在本实施例中, 緩冲小区 1与簇边缘小区 2和簇边缘小区 3中的每一帧的时隙是完全对 齐的,因此簇边缘小区 2中与缓冲小区的时隙 TS0-TS6相对应的时隙分 别为 TS0,-TS6,, 簇边缘小区 3中与緩冲小区的时隙 TS0-TS6相对应的 时隙分别为 TS0"-TS6"。 其中簇边缘小区与緩冲小区 1之间会产生潜在簇间干扰的情形包括 该簇边缘小区将与緩冲小区 1 的一个或多个时隙相对应的时隙分配给 移动终端, 且该移动终端位于簇边缘小区的小区边缘, 若该移动终端使 用的是上行时隙,则该移动终端的上行通信会对在緩冲小区 1内的使用 相对应的时隙进行下行通信的移动终端造成干扰;若该移动终端使用的 是下行时隙,则该移动终端的下行通信会受到在緩冲小区 1内的使用相 对应的时隙进行上行通信的移动终端的干扰。
相应地,簇边缘小区与緩冲小区 1之间不会产生潜在簇间干扰的情 形包括:簇边缘小区未将簇边缘小区的与緩沖小区 1的一个或多个时隙 相对应的时隙分配给移动终端; 或者, 分配该时隙的移动终端位于簇边 缘小区的小区内部, 距离緩沖小区 1较远。
ϋ )用于指示簇边缘小区 2和簇边缘小区 3是否已经将簇边缘小区 的与緩沖小区 1的各个时隙相对应的时隙分配给移动终端的信息, 当该 信息指示与緩冲小区 1 的一个或多个时隙相对应的时隙未分配给移动 终端时, 则第三确定装置 1010,可以确定在该一个或多个时隙上, 该簇 边缘小区与緩冲小区 1之间不会产生潜在簇间干扰。
Hi )用于指示相应的簇边缘小区的在与緩冲小区 1的一个或多个时 隙相对应的时隙上所分配的移动终端的位置信息, 当该信息指示使用緩 冲小区 1 的一个或多个时隙相对应的时隙的簇边缘小区的移动终端位 于潜在干扰区域时, 若该移动终端位于潜在干扰区域时, 如该移动终端 使用的是上行时隙, 则该移动终端的上行通信会对在緩冲小区 1内的使 用相对应的时隙进行下行通信的移动终端造成干扰; 若该移动终端使用 的是下行时隙,则该移动终端的下行通信会受到在緩沖小区 1内的使用 相对应的时隙进行上行通信的移动终端的干扰, 则第三确定装置 1010, 可以确定在该一个或多个时隙上,该簇边缘小区与緩沖小区之间会产生 潜在簇间干扰。
此外, 当考虑到簇边缘小区中存在中继站的情形时, 在簇边缘小区 的边缘的移动终端可以通过中继站与基站进行通信, 因此不需要使用很 大的发射功率, 此时该移动终端虽然处于簇边缘小区的边缘, 但是该移 动终端的上行信号并不会对缓冲小区 1产生潜在簇间干扰。 因此, 当存 在中继站的情形时,位置相关信息中的潜在干扰区域的位置的划分与不 存在中继站时的潜在干扰区域的位置划分可能存在不同。 因此, 存在中 继站时,将簇边缘小区中与緩沖小区 1之间会产生潜在簇间干扰的移动 终端的位置定义为潜在干扰区域。
干扰相关信息不仅仅局限于上述的几种确定标准,本领域一般技 术人员应能根据实际网络的情况,确定簇边缘小区中移动终端是否会与 缓冲小区产生潜在簇间干扰的其他情况。
具体地, 基站 B可以通过有线接口 (cable )或 IP网络等, 将干 扰相关信息发送给緩沖小区 1的获取装置 100,。 同理, 基站 C可以通 过有线接口 (cable )或 IP网络等, 将干扰相关信息发送给緩沖小区 1 的获取装置 100,。 其他的干扰相关信息的发送方式也是可行的, 并都应 处于本发明及其权利要求的保护范围之内。
第一确定装置 101,中的第三确定装置 1010,根据获取的干扰相关信 息来确定簇边缘小区 2和簇边缘小区 3的与緩沖小区 1的各个时隙相对 应的时隙上是否会与緩冲小区 1 之间产生潜在簇间干扰或产生潜在簇 间干扰所对应的时间资仅有一种源配置方式。
具体地, 当获取装置 100,获取的干扰信息为用于指示在缓沖小区 1 的各个时隙相对应的时隙上,簇边缘小区 2与緩沖小区之间是否产生潜 在簇间干扰的信息以及簇边缘小区 3与緩冲小区 1之间是否产生潜在簇 间干扰的信息, 则根据该干扰信息指示, 第三确定装置 1010,可以根据 上述干扰相关信息,确定出簇边缘小区 2和簇边缘小区 3在与緩沖小区 1的各个时隙相对应的时隙是否会与緩冲小区之间产生潜在簇间干扰。
例如, 来自簇边缘小区 2的干扰相关信息指示在时隙 TS0,、 TS4, 和 TS5,上,簇边缘小区 2会与缓冲小区 1之间产生潜在簇间干扰,且时 隙 TS0,配置为下行时隙, 时隙 TS4'配置为上行时隙, 时隙 TS5'配置为 下行时隙; 来自簇边缘小区 3的干扰相关信息指示在时隙 TS0"和 TS4" 和 TS6"上, 簇边缘小区 3会与緩冲小区 1之间产生潜在簇间干扰, 且 时隙 TS0"配置为下行时隙, 时隙 TS4"配置为下行时隙, 时隙 TS6"配置 为上行时隙。
当第三确定装置 1010,确定簇边缘小区 2和簇边缘小区 3在緩沖小 区 1中的一个或多个时隙相对应的时隙上与緩冲小区 1之间不产生潜在 簇间干扰, 或产生潜在簇间干扰所对应的时隙仅有一种上、 下行时隙配 置方式时, 则第三配置装置 1011,将緩冲小区 1的该一个或多个时隙相 应地配置为緩冲小区 1的上行或下行时隙。
对于簇边缘小区 2和簇边缘小区 3与緩冲小区 1之间均不会产生潜 在簇间干扰的一个或多个时隙, 包括 TS1、 TS2和 TS3, 第三配置装置 1011,可以将上述时隙配置为上行时隙或下行时隙。 优选地, 如果对于 一个时隙在簇边缘小区 2和簇边缘小区 3的上、下行时隙配置情形一致, 同为上行时隙或同为下行时隙时, 则第三配置装置 1011,将该时隙配置 为与簇边缘小区 2和簇边缘小区 3相一致的上、 下行时隙配置方式, 也 为上行时隙或下行时隙。例如对于 TS1, 第三配置装置 1011,也将其配置 为下行时隙;而对于一个时隙,其在簇边缘小区 2和簇边缘小区 3的上、 下行时隙配置情形不一致时, 第三配置装置 1011,可以按照一定的策略 将该时隙配置为上行或下行时隙, 例如将 TS2配置为上行或下行时隙。 其中一定的策略包括随机配置或者考虑緩冲小区 1 的上、 下行配置均 衡, 此为本领域技术人员应能理解, 因此在此不予赘述。
对存在潜在干扰的一个或多个时隙, 例如 TS0、 TS4、 TS5和 TS6 中的每一个时隙,通过对各个相邻的簇边缘小区的与緩沖小区 1的时隙 相对应的时隙的上、 下行配置进行比较, 来判断是否会产生簇间干扰。
具体地, 对于时隙 TS0, 在簇边缘小区 2中的 TS0,是下行时隙, 且 在 TS0,上,簇边缘小区 2会与緩沖小区 1之间产生潜在簇间干扰,在簇 边缘小区 3中的 TS0"也是下行时隙, 且在 TS0"上, 簇边缘小区 3会与 緩沖小区 1之间产生潜在簇间干扰, 因为第三确定装置 1010,确定会产 生潜在簇间干扰的簇边缘小区 2和 3的上、下行时隙配置方式只有一种, 同为下行时隙, 因此, 第三配置装置 101 1,将緩沖小区 1的时隙 TS0也 配置为与在簇边缘小区 2和簇边缘小区 3的类型一致的上、下行时隙配 置方式, 也即, 也配置为下行时隙。 对于时隙 TS4,由于在簇边缘小区 2中时隙 TS4,被配置为上行时隙 , 且在该上行时隙上与緩沖小区 1之间会产生潜在簇间干扰,在簇边缘小 区 3中时隙 TS4"配置为下行时隙, 且在该时隙 TS4"上, 簇边缘小区 3 与緩冲小区 1之间会产生潜在簇间干扰。 因为第三确定装置 1010,确定 在簇边缘小区 2和簇边缘小区 3中, 与时隙 TS4相对应的时隙的上、 下 行时隙配置方式不同, TS4,在簇边缘小区 2 中为上行时隙, 而 TS4"在 簇边缘小区 3中为下行时隙, 因此第三配置装置 1011,在緩沖小区 1 中 将该时隙 TS4设为保留 (Reserved ) , 也即不分配用于作上行或下行通 信。
对于时隙 TS5, 第三确定装置 1010,确定虽然簇边缘小区 2和簇边 缘小区 3对于时隙 TS5的相应的时隙的上、 下行时隙配置方式不一致, 但是仅有簇边缘小区 2中的与时隙 TS5相对应的下行时隙 TS5,上, 簇 边缘小区 2会与緩冲小区 1之间产生潜在簇间干扰, 而在簇边缘小区 3 中的与时隙 TS5相对应的上行时隙 TS5"上, 簇边缘小区 3不会与緩沖 小区 1之间产生潜在簇间干扰, 因此, 第三配置装置 101 1,将时隙 TS5 配置为与緩沖小区 1之间会产生潜在簇间千扰的簇边缘小区 2所采用的 上、 下行时隙配置方式相一致的下行时隙;
对于时隙 TS6, 第三确定装置 1010,确定仅有簇边缘小区 3中的与 TS6相对应的上行时隙 TS6,上,簇边缘小区 3会与緩沖小区 1之间产生 潜在簇间干扰, 而在簇边缘小区 2中的 TS6相对应的上行时隙 TS6"上, 簇边缘小区 2不会与緩冲小区 1之间产生潜在簇间干扰, 因此, 第三配 置装置 1011,将时隙 TS6配置为与会与緩沖小区 1之间产生潜在簇间干 扰的簇边缘小区 3所采用的上、 下行时隙配置方式相一致的上、 下行时 隙配置方式, 也即, 基站 A将 TS6配置为上行时隙。
在一个变化的实施例中,緩冲小区 1与至少两个小区簇的多个簇边 缘小区相邻, 例如, 緩沖小区与同属于一个小区簇的簇边缘小区 2和 4 相邻, 与同属于另一个小区簇的簇边缘小区 3和 5相邻, 甚者还与又一 个小区簇中的簇边缘小区相邻(图中未示出)。 在同一个小区簇内, 所 有的小区的上、 下行时隙配置方式都是一致的, 即同一个时隙在同一个 小区簇内的不同小区中均配置为上行时隙或均配置为下行时隙, 但是, 对于一个具体的时隙, 同一个小区簇内的不同小区的干扰情况未必一 致。例如,对于时隙 TS0, 在同一个小区簇内的簇边缘小区 2在时隙 TS0 所对应的下行时隙 TS0,上,簇边缘小区 2会与缓沖小区 1之间产生潜在 簇间干扰, 而簇边缘小区 4在时隙 TS0所对应的下行时隙上,簇边缘小 区 4不会与緩冲小区 1 之间产生潜在簇间干扰。 因此, 第三确定装置 1010,只需考虑会与緩冲小区 1之间产生潜在簇间干扰的簇边缘小区 2。 此外, 只要会与緩冲小区 1之间产生潜在簇间干扰的簇边缘小区使用的 是同一种上、 下行时隙配置方式, 即同为上行时隙或同为下行时隙, 第 三配置装置 1011,就可以为緩冲小区 1配置为与会与緩沖小区 1之间产 生潜在簇间干扰的小区上、 下行时隙配置方式相一致的时隙。
在另一个变化的实施例中,当获取装置 100,中获取的干扰信息为用 于指示簇边缘小区 2和簇边缘小区 3是否已经将与緩沖小区 1的一个或 多个时隙相对应的时隙分配给移动终端的信息, 例如, 基站 B 将时隙 TS3,未分配给移动终端的信息通过有线接口(cable )或 IP网络等发送 给基站 A, 则第三确定装置 1010,根据簇边缘小区 2未将与时隙 TS3 相对应时隙 TS3,分配给移动终端的信息, 确定在该时隙 TS3上, 簇边 缘小区 2不会与緩冲小区 1之间产生潜在簇间干扰。
在另一个变化的实施例中, 参见图 2, 获取装置 100,获取的干扰信 息为用于指示簇边缘小区 2和簇边缘小区 3在于緩沖小区 1的一个或多 个时隙相对应的时隙上分配的移动终端的位置信息。 例如, 当该位置信 息指示基站 B将时隙 TS4,分配给移动终端, 且该移动终端位于簇边缘 小区 2的会与緩冲小区 1之间产生潜在簇间干扰的区域的位置相关信息 时, 基站 B通过有线接口 (cable )或 IP网络等发送给获取装置 100,, 则第三确定装置 1010,根据时隙 TS4分配给移动终端的位置相关信息, 例如, 确定 TS4,相对应的时隙 TS4上簇边缘小区 2会与缓沖小区 1之 间产生潜在簇间干扰。
第六实施例
第六实施例中的第一配置装置为第四实施例和第五实施例的结合 的一种优选的实施方式。
参照图 2进行说明。 首先, 基站 A中的获取装置获取簇边缘小区 2 和簇边缘小区 3分别对应的资源分配相关信息,其中资源分配相关信息 包括上、 下行时隙的配置信息和干扰相关信息, 其中, 配置信息和干扰 信息分别如上述第一实施例和第二实施例所述。
然后基站 A的第四确定装置根据上、下行时隙的配置信息, 首先确 定第一小区簇 CC1和第二小区簇 CC2的与緩冲小区 1 中的各个时隙相 对应的时隙的配置方式相一致, 当第四确定装置确定第一小区簇 CC1 和第二小区簇 CC2的与緩冲小区 1 中的一个或多个时隙相对应的时隙 的配置方式相一致时, 则第四配置装置与在第一小区簇 CC1 和第二小 区簇 CC2 中配置方式相一致地将该一个或多个时隙配置为緩沖小区 1 的上行或下行时隙, 以使得緩沖小区 1与第一小区簇 CC1、 第二小区簇 CC2之间不产生簇间干扰。
当第四确定装置确定第一小区簇 CC1和第二小区簇 CC2中的与緩 冲小区 1中的一个或多个时隙相对应的时隙的配置方式不一致时,第四 确定装置进一步根据干扰信息,对在簇边缘小区 2和簇边缘小区 3中上、 下行配置方式不一致的时隙再利用第四确定装置确定簇边缘小区 2 和 簇边缘小区 3的与緩冲小区 1的各个时隙相对应的时隙上是否会与緩冲 小区 1 之间产生潜在簇间干扰或产生潜在簇间干扰所对应的时间资仅 有一种配置方式, 然后第四配置装置为满足上述条件的时隙配置为上行 或下行时隙。 本领域技术人员应能理解, 在此不予赘述。
在一个变化的实施例中, 即使对于时隙 TS4相对应的时隙上, 当簇 边缘小区 2和簇边缘小区 3均会与緩冲小区 1之间产生潜在簇间干扰, 且簇边缘小区 2和簇边缘小区 3所设置的上、下行时隙的配置方式不一 致时, 其中簇边缘小区 2将 TS4相对应的时隙 TS4,设置为上行时隙, 簇边缘小区 3将 TS4相对应的时隙 TS4"设置为下行时隙, 第三配置装 置 101 1,仍可以将该时隙 TS4分配给在緩冲小区内的处于非潜在干扰区 域内的移动终端作为上行时隙, 因为分配的移动终端位于非潜在干扰区 域, 因此, 该移动终端的上行通信不会干扰簇边缘小 3的以时隙 TS4" 进行下行通信的移动终端,且緩冲小区 1内的移动终端在时隙 TS4进行 上行通信,簇边缘小区 2内的移动终端在时隙 TS4,也采用上行通信, 因 此緩冲小区 1与簇边缘小区 2之间也不会产生簇间干扰。
在一个变化的实施例中, 緩沖区域包括多个其他緩沖小区, 緩冲区 域中的多个緩冲小区之间的上、 下行时隙的配置方式可以不完全相同。 因此, 当緩冲小区 1的上、 下行时隙的配置方式确定以后, 緩沖小区 1 的通知装置可以将其上、下行时隙的配置相关信息通知緩沖区域的其他 緩冲小区。 其中资源配置相关信息包括配置信息和干扰信息。
相应地, 与緩冲小区 1相邻的其他緩冲小区的获取装置接收到来自 缓冲小区 1 的上、 下行时隙的配置相关信息和 /或干扰相关信息后, 获 取装置也将缓冲小区 1看作为一个簇边缘小区,并按照本说明书前述的 方式为本其他緩沖小区配置上行或下行资源, 在此不予赘述。
以上为对第一小区簇 CC1和第二小区簇 CC2的时隙与緩冲小区 1 完全对齐的情形进行具体描述, 当第一小区簇 CC1、 第二小区簇 CC2 与緩冲小区 1的时隙不完全对齐或不完全同步时,上文描述的技术方案 也完全适用。
具体地, 图 5为根据本发明的另一个具体实施例的簇边缘小区 2和 簇边缘小区 3的上、 下行时隙配置的示意图。 其中, 簇边缘小区 2的一 帧中的各个时隙与缓冲小区 1的一帧中的各个时隙没有完全对齐, 而簇 边缘小区 3的一帧中的各个时隙与緩冲小区 1的的一帧中的各个时隙对 齐。每个与緩沖小区 1相邻的簇边缘小区与緩沖小区 1的时隙可以均不 对齐, 或者其中一个或多个相邻的簇边缘小区与緩冲小区 1对齐。
获取装置 100获取了簇边缘小区 2和簇边缘小区 3的各自的帧格式 的相关信息, 其中, 包括簇边缘小区 2和簇边缘小区 3各自的一帧中的 每个时隙的起始时间和终止时间。 因此, 第二确定装置 1010可以才艮据 簇边缘小区 2和簇边缘小区 3的一帧中的每个时隙的起始时间和终止时 间, 判断出其与緩冲小区 1的各个时隙之间的对应关系, 其中, 时间上 至少部分重叠的时隙为相对应的时隙。
以 TS1为例, 簇边缘小区 2中的与緩沖小区 1的时隙 TS1相对应 的时隙为 TSO,和 TS1,, 簇边缘小区 3中的与緩沖小区 1的时隙 TS1相 对应的时隙为 TS1,,。
则对于第四实施例的一个变化例中, 第二确定装置 1010确定簇边 缘小区 2将与緩冲小区 1的时隙 TS0相对应的时隙 TS0,、 TS1 '均配置 为下行时隙, 且簇边缘小区 3将与緩冲小区 1 的时隙 TS0相应的时隙 TS0"配置为下行时隙。 因此, 相应地, 第二配置装置 1011将緩冲小区 1中的时隙 TS0也配置为下行时隙。 这样, 在时隙 TS0上,緩冲小区 1、 簇边缘小区 2和 3在上述时隙均为下行时隙, 以使得緩冲小区 1与簇边 缘小区 2和簇边缘小区 3之间不会产生簇间干扰。
仍参照图 5 , 对本发明的第五实施例的一个变化例进行简要说明如 下:
获取装置 100'获取的干扰相关信息包括: 簇边缘小区 2 的与时隙 TS4相对应的时隙 TS3,上,簇边缘小区 2会与緩冲小区 1之间产生潜在 簇间干扰, 簇边缘小区 3的与时隙 TS4相对应的时隙 TS4" 上, 簇边缘 小区 3会与緩冲小区 1之间产生潜在簇间干扰。
因此, 第三确定装置 1010,确定: 对于时隙 TS4, 在簇边缘小区 2 中与时隙 TS4相对应的时隙 TS2,配置为上行时隙, 且在时隙 TS2,上, 簇边缘小区 2不会与緩冲小区 1之间产生潜在簇间干扰,在簇边缘小区 2中与时隙 TS4相对应的时隙 TS3,配置为下行时隙, 且在时隙 TS3,上, 簇边缘小区 2会与緩冲小区 1之间产生潜在簇间干扰, 在簇边缘小区 3 中与时隙 TS4相对应的时隙 TS4"被配置为下行时隙, 且在该时隙 TS4" 上, 簇边缘小区 3与緩冲小区 1之间会产生潜在簇间干扰。
因为第三确定装置 1010,确定在簇边缘小区 2和簇边缘小区 3中, 会与緩沖小区 1 之间产生潜在簇间干扰的 TS4相对应的时隙 TS3,和 TS4"均配置为下行时隙, 因此第三配置装置 101 1,将时隙 TS4配置为与 会与緩沖小区 1之间产生潜在簇间干扰的上、下行时隙配置方式一致的 上、 下行时隙配置, 也即, 基站 A将 TS4配置为下行时隙。
在某些情况下, 例如上、 下行业务分布发生变化等情况下, 簇边缘 小区 2和 /或簇边缘小区 3会动态地改变其上下行时隙配置, 并生成新 的资源分配相关信息。 此时, 获取装置 100和第一确定装置 101将重复 各自的步骤, 即根据簇边缘小区 2和 /或簇边缘小区 3的更新的资源分 配相关信息, 重新确定本緩冲小区的时隙配置方案。
以上为从緩沖小区 1的基站 A的角度对本发明进行描述,以下将从 与缓冲小区 1相邻的小区簇的基站的角度对本发明进行描述。
图 9 示出了根据本发明的第二方面的在无线通信网络的与緩沖小 区 1相邻的小区簇的基站中用于辅助緩沖小区 1的基站配置上、下行时 隙的辅助配置装置 20框图。 图 9所示的辅助配置装置 20位于以图 1所 示的非簇边缘小区 6的基站 D中。 辅助配置装置 20包括生成装置 200 和发送装置 201。
对属于与緩冲小区 1相邻的小区簇, 以第一小区簇 CC1 为例, 第 一小区簇 CC1 中的非簇边缘小区 6中的基站 D根据用于指示第一小区 簇 CC1 中与缓沖小区 1相邻的簇边缘小区是否已经将簇边缘小区的一 个或多个时隙相对应的时隙分配给移动终端的信息和 /或用于指示簇边 缘小区中分配有緩冲小区 1 的一个或多个时隙相对应的时隙的移动终 端的位置信息来生成干扰相关信息, 其中, 干扰相关信息用于指示与缓 冲小区 1的一个或多个时隙相对应的时隙上, 簇边缘小区与緩冲小区 1 之间是否会产生潜在簇间干扰的信息。 以下以与緩沖小区 1相邻的簇边 缘小区为簇边缘小区 2为例进行说明。基站 D可以通过有线接口( cable ) 或 IP网络等与基站 B进行通信。 上面虽以非簇边缘小区 6中的基站 D为例进行说明,但本领域技术人员应能理解上述步骤也可适用于小区 簇内的簇边缘小区。
具体地, 生成装置 200可以通过有线接口 (cable ) 或 IP网络等, 从基站 B处获取簇边缘小区 2的资源分配相关信息。 获取的信息为用 于指示簇边缘小区 2是否已经将与緩冲小区 1的一个或多个时隙相对应 的时隙分配给移动终端的信息。 例如, 基站 B将与缓冲小区 1 的时隙 TS3相对应的时隙 TS3,未分配给移动终端, 则生成装置 200根据上述 信息, 生成干扰相关信息, 包括在时隙 TS3相对应的时隙 TS3'上, 簇 边缘小区 2不会与緩冲小区 1之间产生潜在簇间干扰。 在一个变化的实施例中, 参见图 2, 当生成装置 200获取的信息为 用于指示簇边缘小区 2中与緩冲小区 1的一个或多个时隙相对应的时隙 上分配的移动终端的位置信息。 例如, 该位置信息指示基站 B 将时隙 TS4,分配给移动终端,且该移动终端位于簇边缘小区 2的边缘会与緩冲 小区 1之间产生潜在簇间干扰的区域时,则生成装置 200生成干扰相关 信息, 包括在时隙 TS4相对应的时隙 TS4,上该簇边缘小区 2会与緩冲 小区 1之间产生潜在簇间干扰。
然后,发送装置 201向緩冲小区 1的基站 A发送本基站所在的小区 簇的资源分配相关信息, 其中, 资源分配相关信息包括簇边缘小区 1与 緩冲小区 1之间的干扰相关信息。
发送装置 201可以在基站 B预先设定好每个帧的各个时隙的上、下 行时隙配置信息, 并已将各个时隙预分配给或确定未分配给移动终端 后, 将干扰相关信息发送给緩沖小区 1。
在一个变化的实施例中, 生成装置 200可以省略, 则发送装置 201 直接向基站 A发送簇边缘小区 2的资源分配相关信息,其中, 资源分配 相关信息包括簇边缘小区 2与緩冲小区 1之间的干扰相关信息。 其中, 干扰相关信息包括以下任一项或任多项:
- 用于指示第一小区簇 CC1中与緩冲小区 1相邻的簇边缘小区 2 是否已经将与緩冲小区 1 的一个或多个时隙相对应的时隙分配给移动 终端的信息;
- 用于指示第一小区簇 CC1的簇边缘小区 2在与緩冲小区 1的一 个或多个时隙相对应的时隙上所分配的移动终端的位置信息。
在另一个变化的实施例中,发送装置 201向基站 A发送簇边缘小区 2的资源分配相关信息, 其中, 资源分配相关信息包括上、 下行时隙配 置信息。
在另一个变化的实施例中,发送装置 201向緩冲小区 1的基站 A发 送簇边缘小区 2的资源分配相关信息,其中,资源分配相关信息包括上、 下行时隙配置信息和干扰相关信息。
在某些情况下, 例如上、 下行业务分布发生变化等情况下, 基站 B 会动态地改变其上、 下行时隙配置。 此时, 辅助配置装置 20的生成装 置 200和发送装置 201将重复执行各自的步骤,发送装置 201将新的资 源分配相关信息提供给基站 A。
生成装置 200和发送装置 201所完成的上述步骤完全可以由第一小 区簇 CC1 内的任意一个小区的基站所完成, 只要第一小区簇 CC1 内的 基站之间可以相互通信。 当上述步骤由簇边缘小区 2的基站所执行时, 基站 B的生成装置可以直接对本基站 B获取的资源分配相关信息进行 操作。
以上对本发明的实施例进行了描述, 但是本发明并不局限于特 定的系统、 设备和具体协议, 本领域内技术人员可以在所附权利要 求的范围内做出各种变形或修改。
