Description

在最新的 UMTS标准演进中, 又引入了 HSDPA多点传输 (HSDPA Multiflow Transmission, HSDPA-MF-Tx )技术, 该技术的原理是, 当 UE 在同频的多个小区覆盖区域内时, 网络侧可以将其配置为 MF-Tx状态, 此 时 UE可以同时在两个小区内接收 HSDPA业务。

另外, 本文中术语"***,,和"网络"在本文中常被可互换使用。本文中术 语"和 /或,,, 仅仅是一种描述关联对象的关联关系, 表示可以存在三种关系, 例如, A和 /或 B , 可以表示: 单独存在 A, 同时存在 A和 B, 单独存在 B 这三种情况。 另外, 本文中字符" /,,, 一般表示前后关联对象是一种"或,,的 关系。
在本发明实施例中, 由无线网络控制器 (Radio Network Controller, RNC )根据终端上报或协议定义的终端在 MF-Tx下 HS-SCCH接收能力信 息通知基站, 然后基站据此来合理分配终端的 HS-SCCH资源信息, 资源信 息包含 HS-SCCH码道信息, 以保证资源分配的结果(分配的 HS-SCCH信 道数)在终端的处理能力范围之内。
其中, 终端上报或协议定义的终端在 MF-Tx下 HS-SCCH接收能力信 息可以是终端在终端发给 RNC的 RRC信令中携带 HS-SCCH接收能力信 息, 或在协议中定义 HS-SCCH接收能力信息。 假如 UE的 MF-Tx服务小 区个数为 X , 则定义 UE在每个服务小区最大接收 i条 HS-SCCH, 定义 UE 在所有服务小区最大接收 j条 HS-SCCH, j=n*x。 n可取小于或等于 1的整 数。 比如, i=4, j=3*x; 当 UE配置的 MF-Tx服务小区个数为 2, 此时 UE 在每个服务小区最大接收 4 条 HS-SCCH, 在两个小区内最大接收 6 条 HS-SCCH。 一般地, 在网络侧的 RNC处应当配置有 i和 /或 j的信息, 在基 站处配置有 i的信息。
如, 在如图 1所示的网络覆盖情况下, 此时, UE可以同时在工作频点 相同的两个小区 ( Celll和 Cell2 )内接收 HSDPA业务, 同时, Celll和 Cell2 分别为基站 1和基站 2下的小区。 则, 结合上一段中配置的情况, 网络侧 可以配置为: 基站 1配置 3条 HS-SCCH, 基站 2配置 3条 HS-SCCH; 或 基站 1配置 2条 HS-SCCH, 基站 2配置 4条 HS-SCCH。

组合的方式具体示例为:
(1) 如果 M=l , N=2时, 对应于一个频点上的两个小区, 即 fl频点上 的两个小区。 如图 2中, cell 1和 cell 2同时发送 HSDPA数据给 UE;
(2) 如果 M=2, Nl=l , N2=l时, 对应于两个频点上的两个小区, 即 fl 频点上的一个小区, 和 £2频点上的一个小区。 如图 2中, cell 1和 cell 2'同 时发送 HSDPA数据给 UE; 同理也可以是 cell 2和 cell 1 '的组合, 以及 cell 2和 cell 3,的组合等等;
(3) 如果 M=2, Nl=2 , N2=2时, 对应于两个频点上的四个小区, 即 f 1 频点上的两个小区, 和 £2频点上的两个小区。 如图 2中, cell 1, cell2, cell l ',cell2'同时发送 HSDPA数据给 UE; 同理也可以是 cell 2, cell 3, cell 2',cell 3,的组合等等。
如无特别说明,本发明实施例中的 MF-Tx的具体模式可参考以上描述。 以下主要介绍, 在 MF-Tx模式下, 进行资源配置的具体方式。
如图 3 所示, 为本发明实施例中的资源分配方法的一个具体流程示意 图, 该方法包括如下流程:
101、 根据终端在配置 HSDPA多点传输模式下 HS-SCCH最大监听信 道数的能力信息生成资源指示信息, 其中, 所述资源指示信息用于指示所 述基站为所述终端在所述基站对应的服务小区内分配 HS-SCCH。
所述的终端在配置 HSDPA多点传输模式下 HS-SCCH最大监听信道数 的能力信息可以通过终端在终端发给 RNC的 RRC消息中携带或者在协议 中定义。
具体的, 所述终端在配置 HSDPA多点传输模式下 HS-SCCH最大监听 信道数的能力信息可包括终端在基站对应的服务小区最大接收 i 条 HS-SCCH和终端在所有服务小区最大接收 j条 HS-SCCH, 并小于或等于: j=n*x, JL j>=i;
其中, x代表为所述终端配置的所述 HSDPA多点传输服务小区的总数, j和 i均为大于或等于 1的整数, n代表大于或等于 1的整数。 一般而言, RNC通过终端对小区的测量上报, 同时结合自身的算法来 决定 HSDPA多点传输服务小区。 在本发明实施例中, 有很多事件会触发终 端的测量上报, 比如现有的 1A或 1D测量事件, 当小于或等于一定条件时, RNC会判定为终端建立 (新的 ) HSDPA多点传输服务小区, 此时 RNC知 道终端当前的服务小区总数和对应的服务小区 (基站)标识。 则 RNC可以 据此和终端上报或协议定义的终端在配置 HSDPA 多点传输模式下 HS-SCCH最大监听信道数的能力信息生成对应的资源指示信息。
比如, 1 : 接收终端发送的接入请求消息; 2: 根据所述接入请求消息 确定为所述终端建立 HSDPA多点传输, 并确定建立 HSDPA多点传输的服 务小区对应的基站; 3:获得终端上报或协议定义的所述终端在配置 HSDPA 多点传输模式下 HS-SCCH最大监听信道数的能力信息。
102、 将所述资源指示信息发送给基站。 其中, 资源指示信息可包含在 RNC发给基站的控制信令中, 比如无线链路建立请求消息 (RADIO LINK SETUP REQUEST ), 无线链路添加请求消息 (RADIO LINK ADDITION REQUEST ) 、 无 线 链 路 重 配 置 请 求 消 息 ( RADIO LINK RECONFIGURATION REQUEST ), 或者资源指示信息也可包含在 RNC发 给基站的用户数据中, 比如 FP ( Frame Protocol , 帧协议)数据。
具体发送资源指示信息的方式可以有两种, 一种是不限时序的向多个 基站分别发送对应的资源指示信息; 另一种是依次顺序向多个基站发送对 应的资源指示信息。
则对应前一种情况, 本步骤具体为, 向基站发送资源指示信息, 所述 资源指示信息中包括所述终端在所述基站对应的服务小区最大分配的 HS-SCCH信道数,其中,在所述基站对应的服务小区最大分配的 HS-SCCH 信道数小于或等于 i。 并且 RNC在向多个基站发送资源指示信息时, 要保 证各基站对应的服务小区最大分配的 HS-SCCH信道数之和小于或等于 j , 即保证所述终端在所有服务小区最大分配的 HS-SCCH信道数之和小于或 等于 J。
对应后一种情况, 本步骤具体为, 向第一基站发送资源指示信息; 获 得所述第一基站返回的资源分配信息, 其中, 所述第一基站返回的资源分 配信息中所述第一基站对应的服务小区最大分配的 HS-SCCH信道数小于 或等于 i;根据所述第一基站返回的资源分配信息和所述终端在配置 HSDPA 多点传输模式下 HS-SCCH 最大监听信道数的能力信息确定向第二基站发 送的资源指示信息, 其中, 在向所述第二基站发送的资源指示信息中的所 述终端在所述第二基站对应的服务小区最大分配的 HS-SCCH信道数小于 或等于 i, 所述终端在所有服务小区对应的最大分配的 HS-SCCH信道数之 和小于或等于 j。
即, 在依次向基站发送资源指示信息, 根据前面基站返回的资源分配 信息中已分配的 HS-SCCH信道数以及 i、 j , 来确定向下一个基站发送的资 源指示信息中的该基站对应的服务小区的 HS-SCCH 的最大分配的 HS-SCCH 信道数, 并保证所述终端的所有服务小区对应的最大分配的 HS-SCCH信道数之和小于或等于 j。 在依次发送资源指示信息的情况中, 第一个发送的资源指示信息为隐式指示信息, 即, 不发送具体信道数限制, 由基站自行分配终端在对应的服务小区接收 HS-SCCH的信道数,由于基站 上也有设置 i值, 该 i值由协议定义, 因而也可以保证其分配的 HS-SCCH 的信道数符合要求。
103、 接收所述基站返回的资源分配信息, 所述资源分配信息中包括基 站为所述终端在所述基站对应的服务小区内分配的 HS-SCCH的信道数,其 中,为所述终端在所述基站对应的服务小区分配的 HS-SCCH的信道数小于 或等于所述终端在配置 HSDPA多点传输模式下 HS-SCCH最大监听信道数 其中,所述资源分配信息中还可包括相关的资源信息,比如, HS-SCCH 码道信息。 同时, 各基站为所述终端在对应服务小区分配的 HS-SCCH的信 道数小于或等于 i, 而所有服务小区的 HS-SCCH的信道数之和小于等于」。
资源分配信息可包含在基站发给 RNC的控制信令中, 比如无线链路建 立响应消息 (RADIO LINK SETUP RESPONSE ), 无线链路添加响应消息 ( RADIO LINK ADDITION RESPONSE )、 无线链路重配置响应消息 ( RADIO LINK RECONFIGURATION RESPONSE ), 或者资源分配信息也 可包含在基站发给 RNC的用户数据中, 比如 FP ( Frame Protocol , 帧协议 ) 数据。 进一步的, 在上述步骤之后还可包括一配置过程, 即向所述终端发送 资源配置信息, 所述信息中包括所述对应的基站为所述终端在服务小区分 配的 HS-SCCH的资源信息, 所述资源信息包含 HS-SCCH码道信息; 并接 收所述终端返回的资源配置响应。
上述从 RNC侧描述了本发明实施例中的资源分配方法, 以下则从基站 侧进行对应的描述。
如图 4所示, 为本发明实施例中的资源分配方法在基站侧的具体流程 示意图。 该流程包括如下步骤:
201、 接收无线网络控制器发送的资源指示信息, 其中, 所述资源能力 指示信息为所述无线网络控制器根据终端在配置 HSDPA 多点传输模式下 HS-SCCH的最大监听信道数的能力信息生成的信息, 用于指示基站为所述 终端在所述基站对应的服务小区内分配 HS-SCCH。
与前述实施例中对应的, 所述终端在配置 HSDPA 多点传输模式下 HS-SCCH最大监听信道数的能力信息可包括终端在基站对应的服务小区最 大接收 i条 HS-SCCH和终端在所有服务小区最大接收 j条 HS-SCCH,并小 于或等于:
j=n*x, JL j>=i;
其中, x代表为所述终端配置的所述 HSDPA多点传输服务小区的总数, n代表小于或等于 1的整数。
202、 才艮据所述资源指示信息生成资源分配信息, 所述资源分配信息中 包括基站为所述终端在所述基站对应的服务小区内分配的 HS-SCCH 的信 道数, 其中, 为所述终端在所述基站对应的服务小区分配的 HS-SCCH的信 道数小于或等于所述终端在配置 HSDPA多点传输模式下 HS-SCCH最大监 听信道数。
对应前述步骤 102 中描述的资源指示信息发送的两种情况, 在本实施 例中, 对应第一种情况, 则所述资源指示信息中包括所述终端在所述基站 对应的服务小区最大分配的 HS-SCCH信道数, 其中, 在所述基站对应的服 务小区最大分配的 HS-SCCH信道数小于或等于 i, 以及为所述终端在所有 服务小区最大分配的 HS-SCCH信道数之和小于或等于 基站实际分配的 服务小区的 HS-SCCH信道数则小于在所述基站对应的服务小区最大分配 的 HS-SCCH信道数,即所述资源分配信息中的基站为所述终端在所述基站 对应的服务小区内分配的 HS-SCCH 的信道数小于等于在所述基站对应的 服务小区最大分配的 HS-SCCH信道数。
对应第二种情况, 即当本地为所述无线网络控制器第一个发送资源指 示信息的基站时, 所述资源指示信息中不包括所述终端在所述基站对应的 服务小区最大分配的 HS-SCCH信道数,所述资源分配信息中所述终端在所 述基站对应的服务小区分配的 HS-SCCH的信道数小于或等于 i。
203、 向所述无线网络控制器发送所述资源分配信息。 这样所述无线网 络控制器可以根据所述资源分配信息与所述终端进行交互以完成资源配 置。
通过上述描述可知, 在网络侧根据终端上报或协议定义的终端在配置 HSDPA多点传输模式下 HS-SCCH最大监听信道数的能力信息通知相关的 基站,并确保基站为终端分配的 HS-SCCH信道数在终端的处理能力范围之 内, 然后网络侧再根据基站分配的 HS-SCCH信道数对终端进行资源配置, 可以保证为终端分配的总的 HS-SCCH信道数不超出终端的处理能力,避免 HS-SCCH资源分配的浪费和由此引起的下行数据传输丟失的问题。
以下以更多的实施例进一步描述上述资源分配方法的细节。 在本例中 假定 UE的 MF-Tx服务小区个数为 X , UE在每个服务小区最大接收 i条 HS-SCCH, UE在所有服务小区最大接收 j条 HS-SCCH。
如图 5 所示, 为不限时序的向多个基站分别发送对应的无线链路建立 请求的情况下的资源配置流程, 其 MF-Tx服务小区情况可参考图 1中的示 例, 在无线链路建立请求和链路建立响应中分别携带资源配置指示信息和 资源配置分配信息, 该流程包括如下步骤:
301、 UE发起接入请求, RNC接收到该接入请求后判决为 UE建立 MF-Tx, 并确定服务小区所在的基站分别为基站 1和基站 2。
302、 RNC向基站 1发送无线链路建立请求,该无线链路建立请求中携 带 Al , A1为基站 1的服务小区的最大分配的 HS-SCCH信道数,且 Al<=i。
303、 基站 1返回链路建立响应, 包含分配的 HS-SCCH资源信息, 对 应的 HS-SCCH信道数为 B1 , 其中 B1<=A1。
304、 RNC向基站 2发送无线链路建立请求,该无线链路建立请求中携 带 A2, A2为基站 2的服务小区的最大分配的 HS-SCCH信道数,且 A2<=i。
305、 基站 2返回链路建立响应, 包含分配的 HS-SCCH资源信息, 对 应的 HS-SCCH信道数为 B2, 其中 B2<=A2。
同时, RNC在确定 A1和 A2时,还进一步确定 Al+A2<=j。 当然, RNC 确定 A1和 A2的步骤需要在步骤 302和 304之前或同时, 并且步骤 302和 303与步骤 304和 305之间没有必然的先后顺序, 可以同时进行, 也可以先 后进行。
306、 RNC在获得基站 1和基站 2返回的响应后,将响应中携带的基站 分配的 HS-SCCH资源信息携带在资源配置信息中发送给 UE, HS-SCCH资 源信息包含 HS-SCCH码道信息。
307、 UE返回资源配置响应, 完成资源配置, 此时 UE在 celll内监听 B1条 HS-SCCH, 在 cell2内监听 B2条 HS-SCCH。 B1和 B2均小于或等于 上述规则。
对应的, 如图 6 所示, 为依次向多个基站分别发送对应的无线链路建 立请求的情况下的资源配置流程, 其 MF-Tx服务小区情况可参考图 1中的 示例, 该流程包括如下步骤:
401、 UE发起接入请求, RNC根据接入请求判决为 UE建立 MF-Tx , 服务小区所在的基站分别为基站 1和基站 2;
402、 RNC向基站 1发送无线链路建立请求, 即隐式包含了资源指示信 息, 指示基站 1为所述终端在其应的服务小区内分配 HS-SCCH;
403、 基站 1返回链路建立响应, 包含分配的 HS-SCCH资源信息, 对 应的 HS-SCCH信道数为 B1 , 其中 Bl<=i。
404、 RNC向基站 2发送无线链路建立请求, 携带 A2, A2为基站 2的 服务小区的最大分配的 HS-SCCH信道数, A2<i, 且 A2<=j-Bl。
405、 基站 2返回链路建立响应, 包含分配的 HS-SCCH资源信息, 对 应的 HS-SCCH信道数为 B2, 其中 B2<=A2。
406、 RNC将分配的 HS-SCCH资源信息携带在资源配置信息中发送给 UE,所述 HS-SCCH资源信息包含 HS-SCCH扰码和 /或 HS-SCCH码道信息, 码道信息具体指信道化码。
407、 UE返回资源配置响应,此时 UE在 celll内监听 B1条 HS-SCCH, 在 cell2内监听 B2条 HS-SCCH。 B1和 B2均小于或等于上述规则。
和图 5中示例的情况, 不同的是 RNC不需要给所有的服务基站发送最 大的 HS-SCCH分配个数指示。 一般来说, 图 5中描述的实施例比较适合在 MF-Tx服务小区同时建立时使用; 而图 6中描述的实施例比较适合 MF-Tx 服务小区先后建立时使用。
图 5和图 6中的场景是 UE的服务小区在单频点的两个小区的场景。根 据前述的描述, MF-Tx包含的模式还有很多, 如图 2中示例的情况。 如表 所示 1 , 用 Cell x-y标识某一频点的某一服务小区, x表示小区所在的频率, y表示同一个频率上小区的编号, 需要注意的是, 表格中列出的小区为 MF-Tx服务小区的组合。比如 UE的 MF-Tx服务小区可能是 Cell 1-1, Cell 1-2: Cell 2-1, Cell 2-2, 也可能是其他组合。
表 1 :
Figure imgf000016_0001
如果 UE的服务小区在不同的基站上时, 此时假定 HSDPA多点传输服 务小区所在基站为基站 1 ,基站 2,基站 3 , 基站 n;对应基站下的 HSDPA 多点传输服务小区个数为 nl , n2 , n3, ..., ηη; 服务小区总数为 χ , x=nl+n2+n3+...+ηη。对应的 HS-SCCH资源分配的规则为 ,假如 UE的 MF-Tx 服务小区个数为 X , 则 UE在每个服务小区最大接收 i条 HS-SCCH, UE在 所有服务小区最大接收 j条 HS-SCCH。 比如 i=4, j=3*x。
则, 此时图 5示例的实施例只需要相应的调整设定的各基站 1的最大 分配的 HS-SCCH信道数, 即 B1+B2+B3... <= A1+A2+A3... <=j , AK=i, A2<=i, A3<=i, ...。 当然, 同一个基站下可能有多个服务小区, 则向该基 站发送的无线链路建立请求中携带多个服务小区对应的 Ai值。 图 6中的 实施例的调整也类似, 只是也不需要向第一个基站发送 Ai值即可。
在上述实施例中, RNC根据终端上报或协议定义的终端在配置 HSDPA 多点传输模式下 HS-SCCH 最大监听信道数的能力信息, 携带最大的 HS-SCCH信道数请求基站分配 HS-SCCH资源信息,使得在配置 MF-Tx时, 网络侧保证分配的 HS-SCCH在 UE的处理能力之内, 避免 UE和网络侧的 HS-SCCH配置信息不一致问题。
