Description

一种调度请求信号的发送方法及装置
技术领域
本发明涉及通信系统的上行信号发送方法， 尤其涉及长期演进（LTE, Long Term Evolution )移动终端向基站发送调度请求信号的方法及相应的装 置。
背景技术
图 1示出了 LTE系统的时分双工 （ TDD, Time Division Duplex )模式下 的帧结构示意图， 该帧结构又称为第二类帧结构， 即 frame structure type 2。 在这种帧结构中， 一个 10ms (占 307200 Ts, 其中 30720 Ts/ms ) 的无线帧被 分成两个半帧， 每个半帧的长度为 5ms (即 153600 Ts ) , 且每个半帧包含 5 个子帧， 每个子帧的长度为 lms, 其作用如表 1所示； 其中， D表示用于传 输下行信号的下行子帧， U表示用于传输上行信号的上行子帧 （或称为普通 上行子帧） 。 另外， 一个上行 /下行子帧又分成 2个 0.5ms的时隙； S表示特 殊子帧，该特殊子帧包含三个特殊时隙， 即下行导频时隙（ DwPTS , Downlink Pilot Time Slot ) 、 保护间隔 （GP, Guard Period )及上行导频时隙 （UpPTS , Uplink Pilot Time Slot ) 。 在实际系统中， 上、 下行配制的索引会通过广播消 息通知给用户设备 ( UE, User Equipment ) 。
表 1
Figure imgf000003_0001
LTE系统的频分双工 （FDD, Frequency Division Duplex )模式的帧结构 又称为第一类帧结构， 即 frame structure type 1 , 如图 2所示。 一个 10ms的无 线帧被分成 20个 0.5ms的时隙，相邻的 2个时隙组成一个长度为 1ms的子帧， 即子帧 i由时隙 2i和 2i+I组成， 其中 i=0，l，2， ...9。 在 FDD模式下， 10个子 帧都用于上行或下行信号的传输， 上、 下行信号通过不同的频带进行区分。
LTE系统中的资源分配以物理资源块（PRB, Physical Resource Block, 简称为资源块 RB, Resource Block )为单位， 一个 PRB在频域上占 12个子 载波 ( Subcarrier , 或称为资源元素 RE , Resource Element； 每个子载波为 15kHz ) , 在时域上占一个时隙 , 即在时域上占据 7个常规循环前缀（ Normal CP, Normal cyclic prefix )或 6个扩展循环前缀 ( Extended CP , Extended cyclic prefix )的 SC-FDMA符号。如果上行系统带宽在频域上对应的 RB总数为 NR U B L , 则 RB的索引为 0、 1 NR u B L -\ , RE的索引为 0、 1 K 其 中， N^为一个 RB在频域上所对应的子载波数。 以常规循环前缀为例， PRB 的结构如图 3所示。
调度请求（ SR, Scheduling Request )是当 UE希望用更高的数据速率发送 信号时向基站发送的请求信号， 该 SR 信号规定在物理上行控制通道 ( PUCCH, Physical Up Control Channel )上传输， UE通过基站发送的 SR配 置索引 /w获知相应的 SR周期和子帧偏移， 如表 2所示。
表 2
Figure imgf000004_0001
譬如， 当基站发送的 SR配置索引 /^为 6时， UE通过表 2查出 SR周期 为 10ms, 且 SR子帧偏移为 /w-5=6-5=l。
上述表中只是确定 UE如何通过 /5求出 SR信号的发送周期和其子帧偏 移， 而并未明确 UE将 SR信号在哪个无线帧的子帧上发送， 这就意味着 UE 无法保证充分有效地利用无线帧，甚至导致 UE发送的 SR信号不能被基站可 靠地接收。 因此， 目前需要一种方法能够使得 UE根据 SR的发送周期及子帧 偏移确定发送 SR信号的无线帧及子帧。
发明内容

为了解决上述技术问题， 本发明提供了一种调度请求信号的发送装置， 用于 LTE系统用户设备 UE向基站的上行信号的发送， 该装置包括相互连接 的无线帧及子帧确定模块和发送模块， 其中：
无线帧及子帧确定模块，用于根据调度请求 SR子帧偏移和 SR周期确定 发送 SR的无线帧及其子帧位置： 在无线帧时长小于所述 SR周期时， 将总时 长等于 SR周期的多个连续无线帧中首个无线帧的起始子帧移动 SR子帧偏移 后， 确定 SR信号的发送帧和子帧； 在无线帧时长等于或大于 SR周期时， 将 每一无线帧确定为 SR信号的发送帧， 并且： 当无线帧时长等于 SR周期时， 将发送帧的起始子帧移动 SR子帧偏移， 定位到发送帧的子帧； 当无线帧时 长大于 SR周期时， 将无线半帧的起始子帧移动 SR子帧偏移， 定位到发送帧 的子帧； 将确定的发送 SR的无线帧及其子帧位置输出给发送模块；
发送模块， 用于在确定的发送帧的子帧上将 SR信号发向基站。
进一步地，
无线帧及子帧确定模块， 确定发送 SR 的无线帧及其子帧位置是指： 在 SR子帧偏移为 0时， 确定发送帧的系统帧号 满足等式 (lOx ；) modN^ P = 0 ; 在 SR 子帧偏移不为 0 时， 确定发送帧的系统帧号 满足等式

本发明的调度请求信号的发送方法， 用于 LTE系统用户设备 UE向基站 的上行信号的发送， 该方法通过 UE中相应的装置实施， 包括： UE根据 SR 配置索引确定 SR周期和 SR的子帧偏移； UE在无线帧时长小于 SR周期时， 将总时长等于 SR周期的多个连续无线帧中首个无线帧的起始子帧移动 SR子 帧偏移后， 确定 SR信号的发送帧和子帧； 在无线帧时长等于或大于 SR周期 时， 将每一无线帧确定为 SR信号的发送帧， 并且： 当无线帧时长等于 SR周 期时， 将发送帧的起始子帧移动 SR子帧偏移， 定位到发送帧的子帧； 当无 线帧时长大于 SR周期时， 将无线半帧的起始子帧移动 SR子帧偏移， 定位到 发送帧的子帧； UE在确定的无线帧的子帧上将 SR发送给基站。
UE在无线帧时长小于 SR周期时， "将总时长等于 SR周期的多个连续 无线帧中首个无线帧的起始子帧移动 SR子帧偏移后，确定为 SR信号的发送 帧和子帧" 是指： 将总时长等于所述 SR周期的多个连续无线帧中首个无线 帧的起始子帧作为起始位置， 偏移 SR子帧偏移后的子帧所在的无线帧作为 SR信号的发送帧， 将该子帧作为 SR信号的发送子帧。
当无线帧时长等于所述 SR周期时， "将发送帧的起始子帧移动 SR子帧 偏移， 定位到发送帧的子帧" 是指： 将发送帧的起始子帧作为起始位置， 偏 移 SR子帧偏移后的子帧作为 SR信号的发送子帧。
当无线帧时长大于所述 SR周期时， "将无线半帧的起始子帧移动 SR子 帧偏移， 定位到发送帧的子帧"是指： 将无线半帧的起始子帧作为起始位置， 偏移 SR子帧偏移后的子帧作为 SR信号的发送子帧。

410: UE才艮据 SR配置索引确定 SR周期和 SR的子帧偏移， 确定方法如 表 2中所示；
420: UE通过 SR周期和 SR子帧偏移确定发送 SR的无线帧及其子帧位 置； 确定的方法是： UE在无线帧时长小于 SR周期时， 将总时长等于 SR周 期的多个连续无线帧中首个无线帧的起始子帧移动 SR子帧偏移后， 确定 SR 信号的发送帧和子帧； 在无线帧时长等于或大于 SR周期时， 将每一无线帧 确定为 SR信号的发送帧， 并且： 当无线帧时长等于 SR周期时， 将发送帧的 起始子帧移动 SR子帧偏移， 定位到发送帧的子帧； 当无线帧时长大于 SR周 期时， 将无线半帧的起始子帧移动 SR子帧偏移， 定位到发送帧的子帧。
具体的方法如下：
方法一

UE根据满足等式 _ 。丽 mod 10 0的时隙索引 确定发 送帧的子帧；
在上述等式中， mod为取模运算符， ^?? ?5为 81 周期， N( OFFSET 为 SR子 帧偏移， L」为向下取整运算符
方法二： UE将满足等式 +^ 」— , )111。^；? Ρ=0的 确定为 发送帧的系统帧号， 并根据满足该等式时隙索引 确定发送帧的子帧； 其中 mod为取模运算符， Nfl— P为所述 SR周期； N。Fra£„为所述 SR子帧偏移， L」 为向下取整运算符。
430: UE在确定的系统帧号为 的无线帧的子帧上将 SR信号发向基站。

将 N^ P=5, N。FraCTffi=2代入上述等式， 则发送 SR的子帧和无线帧的系 统帧号" ,满足 (10xw, /2」— 2)mod5 = 0：
nf =0时：
由于 N0 TSR=2, 故 =4, 5或 =14, 15
( 10 0+4/2-2 ) mod 5=0 mod 5=0, 符合条件；
( 10 0+5/2-2 ) mod 5 =0.5 mod 5=0, 符合条件；
故子帧 #2即第 3个子帧符合上述条件；
同理， 子帧 #7即第 8个子帧亦符合上述条件；
同理， =1,2, ......的第 3个子帧、 第 8个子帧均符合上述条件。
因此， UE将 SR在每个无线帧的第 3个子帧（子帧 #2, 对应时隙号为 4、 5)和第 8个子帧 （子帧 #7, 对应的时隙号为 14、 15)上发送。
实施例 2

将 N^ P=10, N。FraCTffi=2代入上述等式， 则发送 SR的子帧和无线帧的系 统帧号" ,满足 (lOxw, +L /2」— 2)modl0 = 0:
nf =0时：
由于 N0 TSR=2, 故 =4, 5,或 =14, 15
( 10 χ 0+4/2-2 ) mod 10=0 mod 10=0, 符合条件；
( 10 x 0+5/2-2 ) modl0=0.5modl0=0, 符合条件；
故子帧 #2即第 3个子帧符合上述条件；
( 10 X 0+14/2-2 ) modl0=5modl0=5, 不符合条件；
( 10 0+15/2-2) modl0=5.5modl0=5, 不符合条件；
故子帧 #7即第 8个子帧不符合上述条件；
同理， =1,2, ......的第 3个子帧均符合上述条件。 因此， UE将 SR在每个无线帧的第 3个子帧（子帧 #2, 对应时隙号为 4、 5 )发送。
实施例 3
当 SR周期 N^ 为 20ms, 子帧偏移 N。Fra£„为 12的时候， 发送 SR的子 帧和无线帧的系统帧号 nf满足 (10 X + L / 2」 - N0F )mod NSR p= , 其中 为 时隙索引。
nf=0时:
由于 N0F =\2, 故" s=4, 5
( 10 X 0+4/2-2 ) mod 20=0 mod 20=0, 符合条件；
( 10 X 0+5/2-2 ) mod20 =0.5 mod 20=0, 符合条件；
故第 1个无线帧的第 3个子帧 (即子帧 #2 )符合上述条件；
nf=\时：
( 10 1+4/2-2 ) mod20=10mod20=10, 不符合条件；
( 10 1+5/2-2 ) mod20=10.5mod20=10, 不符合条件；
nf =2时：
( 10 X 2+4/2-2 ) mod20=20mod20=0, 符合条件；
( 10 X 2+5/2-2 ) mod 20=20.5 mod 20 =0 , 符合条件；
nf =3时：
( 10 3+4/2-2 ) mod20=30mod20=10, 不符合条件；
( 10 3+5/2-2 ) mod20=0.5mod20=10, 不符合条件;
因此， UE将 SR在" ,为奇数的无线帧（第 1、 3、 5......个无线帧，即 nf =0、 nf=2, nf=4...... ) 的第 3个子帧 （对应时隙号为 4、 5 )上发送。
