发送上行资源调度请求的方法和用户设备 本申请要求在 2009年 09月 29日提交中国专利局、 申请号为 200910235256.X、发明名称为
"发送上行资源调度请求的方法和用户设备"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
本发明涉及移动通信技术, 特别涉及一种 LTE (Long Term Evolution, 长 期演进)系统中用户设备发送上行资源调度请求的技术。 背景技术
随着移动通信技术的蓬勃发展, 无线通信系统呈现出移动化、 宽带化和 IP化的趋势, 移动通信市场的竟争也日趋激烈。 为应对来自 WiMAX ( World Interoperability for Microwave Access,全球微波接入互通技术 ), Wi-Fi(Wireless Fidelity, 无线保真技术)等传统和新兴无线宽带接入技术的挑战,提高 3G在宽 带无线接入市场的竟争力, 3GPP开展 UTRA ( Universal Terrestrial Radio Access, 全球地面无线接入)长期演进技术的研究, 以实现 3G技术向 B3G (Beyond three Generation,后三代)和 4G的平滑过渡。 LTE系统包括时分双工 ( Time Division Duplex, TDD )和频分双工 ( Frequency Division Duplex, FDD ) 两种双工方式。 频分双工 (FDD), 也称为全双工, 需要两个独立的信道。 一个 信道用来向下传送信息, 另一个信道用来向上传送信息。 两个信道之间存在 一个保护频段, 以防止邻近的发射机和接收机之间产生相互干扰。 时分双工 (TDD), 也称为半双工, 只需要一个信道, 无论向下还是向上传送信息都采用 这同一个信道。
LTE系统分别设计了 FDD和 TDD的帧结构, FDD模式下, 每个 10ms 的无线帧 (Radio Frame)被分为 10个子帧, 每个子帧包含两个时隙, 每时隙长 0.5ms。 TDD的帧结构如图 1所示, 每个 10ms无线帧划分为两个完全相同的 半帧 (Half-frame), 每个半帧由 4个业务子帧和 1个特殊子帧组成, 每个业务 子帧的长度为 lms, 包含两个 0.5ms的业务时隙 (Time Slot, TS ), 特殊子帧
包括 3个特殊时隙, 下行导频时隙(Downlink Pilot Time Slot, DwPTS )用作 下行同步信号的发送, 保护间隔 (Guard Period, GP)用于下行传输转换到上 行传输时的保护间隔, 而上行导频时隙 (Uplink Pilot Time Slot, UpPTS )用 作上行的随机接入。 每个半帧配置一对切换点, 其中下行至上行切换点位于 特殊区域 GP内, 上行至下行切换点位于除业务子帧 #0外的其它业务子帧边 界处, 同一业务子帧的两个业务时隙不能进行上下行切换。 参见表 1 所示, TDD系统的时隙比例配置有多种方案:
表 1
其中, 表 1中上行和下行配置结构的序号为 TDD系统的上下行时隙配置 的图样序号, 相应为图样 0、 图样 1.....图样 6。
PUCCH ( Physical Uplink Control Channel, 物理上行控制信道)承栽上行 控制信息的主要传输信道, PUCCH存在多种传输格式, LTE Rel-8 (版本 8 ) 系统中, 上行资源的 SR ( Scheduling Request, 调度请求)使用其中 Formatl (第一种传输格式)传输, UE ( User Equipment, 用户设备)通过发送调度请 求向 eNB (演进基站) 申请上行资源调度, 从而在后续过程中进行发送緩沖 区状态报告,基站根据该緩沖区状况和信道盾量向 UE调度合适的上行资源进 行数据传输。 LTE Rd-8中调度请求采用周期性发送机制, 每用户在预先配置 的子帧位置和信道资源上进行发送。 由于上行数据传输需要依靠调度请求触 发资源申请, 因此调度请求的发送周期长短直接决定了上行用户数据延迟的 大小。
在 LTE Rel-8高层规范 TS36.331 中对调度请求相关配置的 RRC ( Radio Resource Control,无线资源控制)信令中用于调度请求发送的 PUCCH信道编 号, 以及调度请求的传输周期和子帧位置的联合编码指示 sr-Configlndex进行 了说明,在 LTE R8物理层规范 TS36.213中关于 SR的发送周期和子帧位置有 如下表 2的规定:
表 2.
根据表 2所示, LTE R8高层规范提供了 5ms、 10ms, 20ms, 40ms, 80ms 等传输周期的 SR配置, 最小传输周期为 5ms。 根据表 2可以解析 RRC信令 中携带的 sr-Configlndex R , 当 大于等于 0小于等于 4时, 则 SR的传输周 期为 5ms,每一个传输周期中用于发送 SR的子帧为该传输周期中的第 个子 帧, 当 大于等于 5小于等于 14时, 则 SR的传输周期为 10ms, 每一个传输 周期中用于发送 SR的子帧为该传输周期中的第 -5个子帧, 其他依次类推。
本申请发明人发现, 现有规范中定义了用户设备在激活状态 (Active )、 休眠状态 (Active- "dormant" )和驻留状态 (Camped )之间的延时需求, 其 中: Active- "dormant" 到 Active之间的延迟需求是 10ms左右, 最小传输周 期为 5ms意味着用户每 5ms才能获得一次上行数据传输机会, 用户数据延迟 现象较为严重, 以最小传输周期为 5ms为例, FDD系统中 Active- "dormant" — >Actived的延时计算方法如表 3所示:

图 1为现有技术中 TDD帧结构示意图;
图 2为本发明实施例提供的用户设备发送 SR的流程示意图;
图 3为本发明实施例提供的用户设备结构示意图。 具体实施方式
本发明实施例为减小数据延迟,提出将 SR传输周期配置参数的备选项中 增加设置 2ms或 lms, 当 SR传输周期配置为 2ms或者 lms时, 用户设备可 以获得更多的 SR发送机会以请求上行资源,从而在有数据发送时可以尽快获 得上行资源以发送数据, 从而减小了用户的数据延迟, 靠近上述 Active- dormant" 到 Active之间 10ms延迟需求。 下面分别对 FDD和 TDD两种系 统详细分析本发明技术方案的实现原理。
一、 FDD系统
1、 SR传输周期配置为 2ms时, 用户设备在上行帧中每 2ms得到一次传 输机会, 子帧偏移位置有奇偶两种配置方式, 即: 用于发送上行资源调度请
求的子帧配置为上行栽波中的每一个奇子帧或者每一个偶子帧;
2、 SR传输周期配置为 1ms时, 用户设备在上行帧中的每个子帧均可以 得到一次 SR传输机会, 即: 用于发送上行资源调度请求的子帧配置为上行帧 中的每一个子帧。
如果采用联合编码指示方式, 传输周期和子帧位置的不同配置选项分别 采用一个对应的联合编码指示信息进行标识, 则:
仅将 1ms作为 SR的最小传输周期增加到 SR传输周期配置中时,需要增 加 1种 SR配置选项;
仅将 2ms作为 SR的最小传输周期增加到 SR传输周期配置中时,需要增 加 2种 SR配置选项;
将 1ms和 2ms增加到 SR传输周期配置中,则 SR最小传输周期可以配置 为 lms, 需要增加 3种 SR配置选项。
二、 TDD系统
2ms的 SR传输周期定义为一个 5ms中有两次 SR传输机会,即:如果 SR 传输周期配置为 2毫秒, 则用于发送上行资源调度请求的子帧配置为每个半 帧中的任意两个上行子帧;
lms的 SR传输周期定义为一个 5ms中的每一个上行子帧都有 SR传输机 会, 即: 如果 SR传输周期配置为 1毫秒, 用于发送上行资源调度请求的子帧 配置为各半帧中的每一个上行子帧。
由于表 1 中所示图样 1和图样 5中, 每一个半帧的上下行切换周期中仅 有一个上行子帧, 因此, 即使将 lms和 2ms作为 SR传输周期的配置, 相对 5ms传输周期来说并没有增加 SR传输机会,可以认为 lms和 2ms的 SR传输 周期配置对图样 1和图样 5无效, 仅对其他图样 0、 图样 1、 图样 3、 图样 4 和图样 6有效, 则用户设备荻得配置参数指示信息后, 如果确定传输周期配 置为 2毫秒并且上下行子帧才艮据图样 2或者图样 5配置, 则可以将配置参数 指示信息视为无效参数重新请求; 否则将配置参数指示信息视为有效参数并 根据配置参数指示信息发送上行资源调度请求。
还需要说明的是:
由于上下行配置图样 1和图样 4的一个半帧包含两个上行子帧,所以 1ms 或 2ms的 SR传输周期配置实际上是完全一样的,都是在一个每一个半帧中获 得了两次 SR传输机会;
当 TDD系统 5ms转换点周期情况下一个 5ms最多有 3个上行子帧时,对 于 2ms的 SR传输周期配置, 选择其中任何两个子帧用于发送 SR时, 可以产 生三种选择方式, 例如记为上行子帧编号 0,1,2, 从中任选两个形成 3种不同 的子帧偏移配置, 即 {0,1},{0,2},{1,2} , 因此在进行联合编码时, 需要三种配 置选项进行指示;
这样, 考虑到现有 LTE R8的 SR周期和子帧偏移位置指示采用联合编码 方式时:
仅将 1ms作为 SR的最小传输周期增加到 SR传输周期配置中时,需要增 加 1种 SR配置选项;
仅将 2ms作为 SR的最小传输周期增加到 SR传输周期配置中时, 需要增 加 3种 SR配置选项;
将 1ms和 2ms增加到 SR传输周期配置中,则 SR最小传输周期可以配置 为 lms, 需要增加 4种 SR配置选项。
SR传输周期为 1ms或 2ms时,在其中有些时隙配比下,可以有效缩短用 户数据传输时延, 例如: .
1 )、 TDD采用图样 0、 SR传输周期配置为 lms, 位于所有上行子帧时, 总时延计算如下表 5所示, 可以将数据传输时延有效降低到 10.1ms:
3
位于一个无线帧中序号为 2、 4、 7、 9的子帧时, 总时延计算如下表 6所示, 可以将数据传输时延有效降低到 10.9ms:
3 ) TDD采用图样 1, SR传输周期配置为 lms, 位于所有上行子帧时, 总 时延计算如下表 7所示, 可以将数据传输时延有效降低到 10.7ms:
表 7.
TDD采用图样 1, SR传输周期配置为 2ms, 用于传输位于 SR的子帧为 序号为 2、 3、 7和 8的子帧时, 总时延和 5ms周期时一样。 其他情况本领域 技术人员可以同理推导, 这里不再 详细说明。
这样, SR的传输周期配置参数的备选项的最小设置为 2ms或 lms时, 即 在 SR的传输周期配置参数的备选项增加了 2ms、 或者 lms, 或者还可以增加
10 076933
2ms和 lms, 从而可以提高整个系统在 SR传输周期配置上的灵活性, 可以在 数据时延要求较小时, 利用 2ms或 lms的 SR的传输周期配置减小了用户数 据传输时延, 尽可能的靠近 10ms延迟需求。
参见表 2所示, lms和 2ms可以和其他传输周期的配置选项统一进行联 合编码,例如只增加 lms的 SR传输周期配置时,形成如下表 8所示的联合编 码:
表 8.
为了兼容已有的 LTE R8高层规范提供的 5ms、 10ms, 20ms, 40ms, 80ms 等 SR传输周期的配置,也可以将 lms或 2ms的 SR传输周期单独进行联合编 码, 每一个配置项的联合编码结果用编号 N指示。 针对 lms或 2ms的各种不 同配置方案, 在 R C信令中新增一个参数集合, 与原有联合编码指示参数集 合是并列关系, 用于携带扩展后的配置选项联合编码指示。 扩展方式例如: 首先在现有物理层专用配置 IE ( Information Element, 信息单元) 中增加参数 集合: schedulingRequestConfig-ext SchedulingRequestConfig-ext , 然后在物理 层专用配置 IE 中增加参数集合的具体参数配置值, 其中, 根据 lms或 2ms 的 SR传输周期进行的联合编码结果, 将配置项的编号 N作为 lms或 2ms的 SR传输周期配置项的联合编码指示。 参数集合中的 据物理层增加的 SR 配置选项的编号进行设置。
当 R C信令中并列有两个联合编码的参数集合时, 可以利用多种方式指
6933 示参数集合的有效性, 例如可以在 RRC信令中携带一个单独的指示信息进行 指示, 或者对于有效的参数集合携带具体的参数值, 无效的参数集合不携带 具体参数值或者携带无效参数值等等, 这里不再一一列举了。
这种编码方式下, 2毫秒和 /或 1 毫秒传输周期的各个配置选项进行联合 编码, 其他传输周期的各个配置选项进行联合编码, 形成两组联合编码, 并 且两组联合编码指示信息携带在 RRC信令的不同参数集合中。
如图 2所示, 根据上述原理, 本发明实施例提供了一种 LTE系统中用户 设备发送上行资源调度请求的方法, 包括如下步骤:
5201、 从基站接收 RRC信令;
5202、从 RRC信令中获得用于指示上行资源调度请求的传输周期和用于 发送上行资源调度请求的子帧位置的配置参数指示信息, 传输周期配置参数 的备选项包括 2ms, 或者包括 lms, 或者包括 2ms和 lms;
