Description

一种多载波系统中确认时延的配置装置及方法
技术领域
本发明涉及移动通信领域，尤其涉及一种为多载波配置 E-HICH (增强上 行信道混合自动重传请求应答指示信道）确认时延的方法。 背景技术
TD-SCDMA (时分同步码分多址接入） E-DCH (增强-专用信道）相关的 物理信道有： E-PUCH (增强上行物理信道， Enhanced Uplink Physical Channel )、 E-HICH (增强上行信道混合自动重传请求应答指示信道， Enhanced UL DCH Hybrid Automatic Repeat ReQuest Acknowledgement Indicator Channel )、E-AGCH(增强上行绝对授权信道， Enhanced UL DCH Absolute Grant Channel )。其中， E-HICH是共享的下行信道，用于传输相应 UE的 ACK/NACK 确认反馈以及非调度用户 E-PUCH信道的 TPC和同步偏移（ SS )指令。 一个 信道化码可以携带一个或多个 HARQ (混合自动重传请求)应答信息， 并且每 个 ACK/NACK只在一个单独的时隙以一定长度的特征序列传输。如图 1所示， 根据协议要求， Ue釆用 E-AGCH 6个时隙后的第 1个可用的 E-PUCH承载上 行数据。 E-HICH釆用该 Ue使用的最后的一个 E-PUCH时隙后的 N个时隙后 的第 1个可用 E-HICH承载 Ack/Nack信息。其中， N是 E-HICH时间偏移值， 也就是确认时延， 该值由 Node B (基站)通过物理共享信道重配响应消息中 E-HICH Time Offset LCR信息元素通知 RNC (无线网络控制器） E-HICH确认 时延信息， 如表 1所示， E-HICH确认时延的取值范围为 4 - 15个时隙。
表 1 ： E-HICH Time Offset LCR
Figure imgf000003_0001
E-HICH时间偏移值由 NODEB根据 E-HICH, E-PUCH配置情况选择, 其中一个基本选择原则： 当几个时隙都被配置为 E-PUCH时， 不能出现位于 同一子帧的各 E-PUCH发生 E-PUCH数据时， UE接收 E-HICH数据的子帧与 发生该 E-PUCH数据的子帧的个数差不一致的情况。表 2是 1.28M TDD多载 波 TD-SCDMA系统可能出现配置情况，其中粗体部分表示当 E-HICH配置在 某时隙时， 不同时隙上发生 E-PUCH数据时， 接收 E-HICH数据的子帧与发 生 E-PUCH数据的子帧的个数差不一致的情形 。
表 2: E-HICH, E-PUCH配置情况与 E-HICH确认时延的关系
Figure imgf000004_0001
满足上面要求条件的 E-HICH确认时延有多种， 但是， 在 E-DCH非调度 模式下， E-HICH还需要和 E-PUCH信道做闭环同步功控， 这就需要 E-HICH 时间偏移值 N越小越好， 以保证功控的及时有效， 因此需要 NODEB根据 E-HICH, E-PUCH配置以及功控需求，选择一个合适的确认延时， 即 E-HICH Time Offset LCR的取值。另一方面 Mac-e (媒体接入控制)调度过来前提下，响 应也快， 流量可以越大， 都要求基本选择原则前提下 E-HICH时延越小越好， 当然不同系统也可以才艮据自身处理能力选择一个次优值。
目前 3GPP TD-SCDMA系统已经升级为多载波系统， E-DCH也可以在小 区内多个载波上发送。 在实际网络规划中， 每个载波的配置情况有所不同， 比如， 每个载波的 E-PUCH的时隙资源数可以独立配置， 但现有协议响应消 息仅支持返回一个 E-HICH确认时延给 RNC,不支持各载波不同配置的情形， 因此， 在这种情况下如何优化各个载波上的 E-HICH时间偏移是一个需要解 决的问题。

步骤 201 , RNC建立四载波小区 CELL1 , 频点分别为 fl , f2, β , f4; 步骤 202, RNC向 NodeB发送物理共享信道重配请求消息， RNC通过物 理共享信道重配请求消息在 β、 β两个载波上配置增强-专用信道 E-DCH相 关的共享资源配制信息， E-DCH相关的共享资源包括增强上行绝对授权信道 E-AGCH、增强上行信道混合自动重传请求应答指示信道 E-HICH及增强上行 物理信道 E-PUCH ,其中载波 G E-PUCH占用 TS2、 TS3 , E-HICH占用 TS6, 载波 β上 E-PUCH占用 TS1和 TS2, E-HICH占用 TS6, E-HICH和 E-PUCH 的时隙配置关系如图 3所示。
步骤 203: NodeB接收物理共享信道重配请求消息后， Mac-e根据每个载 波的 E-HICH和 E-PUCH配置信息配置 E-HICH确认时延。配置的 E-HICH确 认时延需满足： 位于同一子帧的各 E-PUCH发生 E-PUCH数据时， UE接收 E-HICH数据的子帧与发生该 E-PUCH数据的子帧的个数差必须一致。
如对于载波 G, E-HICH确认时延可以是 5、 6、 7、 8、 9、 10、 12、 13、 14、 15个时隙， 考虑到确认时延越小越好， 可以将载波 £2的 E-HICH确认时 延定位为 5。 当 UE分配在载波 β上时， 因载波 β的 E-HICH及 E-HICH的 配置与载波 G不同， 若此时为载波 β配置的确认时延与为载波 £2配置的确 认时延相同， 则可能出现问题， 如， 当 E-HICH确认时延为 5个时隙时， 在 第一个子帧的 TS2上发生 E-PUCH数据， UE则在第二个子帧的 E-HICH上接 收 HARQ的指示信息； 在第二个子帧的 TS1上发生 E-PUCH数据， UE也在 第二个子帧的 E-HICH上接收 HARQ的指示信息。 这样 UE无法区分在第二 个子帧上收到的 E-HICH是第一个子帧的 E-PUCH数据的 HARQ指示信息还 是第二个子帧的 E-PUCH数据的 HARQ指示信息， 时序关系如图 4所示。 因 此对于载波 β不能将 E-HICH确认时延配置为 5个时隙。 因此，对于载波 β , E-HICH确认时延可以是 6、 7、 8、 9、 10、 11、 13、 14、 15个时隙， 考虑到 确认时延越小越好， 可以将载波 β的 E-HICH确认时延定位为 6个时隙。 这里假定 Mac-e处理能力满足确认时延大于等于 5个时隙的要求， 但不 同厂家 Mac-e处理能力可能不同， 协议已经考虑 Mac-e处理能力不足会限制 确认时延的选择， 如果 Mac-e 处理能力不满足以上限制， 各载波可以选择 E-HICH确认时延满足 Mac-e处理能力的最小 E-HICH确认时延值，即各载波 的 E-HICH确认时延应在 Mac-e处理能力范围内， 例如当 Mac-e处理时延为 12个时隙时， 载波 £2、 载波 β的 E-HICH时延最佳选择分别为 12、 13个时 隙；
步骤 204, NodeB返回物理共享信道重配响应消息给 RNC, 所述响应消 息中携带各载波的 E-HICH确认时延信息， 具体响应消息内容如表 3所示： 表 3: 物理共享信道重配响应消息
Figure imgf000009_0001
物理共享信道重配响应消息中 E-HICH Time Offset LCR1.28Mcps TDD IE在现有协议基础上进行扩展，以前响应只有 E-HICH Time Offset LCR信元， 不支持多频点不同响应。现在引入新的信元 E-HICH Time Offset LCR1.28Mcps TDD IE, E-HICH Time Offset LCR1.28Mcps TDD IE可以支持多个频点的 E-HICH Time Offset LCR不同配置， E-HICH Time Offset LCRl .28Mcps TDD IE信元包含指示频点信息的 UARFCN (绝对射频信道号)信元及指示各载波的 E-HICH确认时延的 E-HICH Time Offset LCR信元，增加频点信息后可以支持 多个频点不同响应，支持的频点数 maxFrequencyinCell同现有协议多频点小区 的最大频点数， 例如本实施例包含四个载波的频点信息和各载波对应的
E-HICH确认时延信息。
UARFCN信元指示信道号的中心频率即频点信息， 含义如表 4所示: 表 4: UARFCN的结构
Figure imgf000010_0001
E-HICH Time Offset LCR则为现有协议已有单元。
步骤 205: RNC接收到 NodeB响应 , 记录各频点的 E-HICH确认时延信 息。
完成小区内的 E-DCH资源配置后， RNC可以为具有 E-DCH能力的 UE 建立 E-DCH无线承载。 RNC在为 UE配置某个载波上的 E-DCH资源时， 需 要将该载波上的 E-HICH确认时延配置给 UE。
当然， 本发明还可有其他多种实施例， 在不背离本发明精神及其实质的 但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
工业实用性
本发明供了一种多载波系统中 E-HICH确认时延的配置装置及方法， 对 于多载波小区， RNC按照载波配置 E-HICH及 E-PUCH, 基站按照各载波上 E-HICH及 E-PUCH信息为各载波配置其最优的 E-HICH确认时延，避免了各 载波配置不同而 E-HICH确认时延相同时出现异常或强制要求各载波选择相 同的 E-HICH及 E-PUCH配置信息的问题。
