Description

一种数据边界确定方法、 指示信息发送方法及其装置
[0001]本申请要求于 2012 年 05 月 10 日提交中国专利局、 申请号为 201210144267.9、 发明名称为"一种数据边界确定方法、 指示信息发送方法 及其装置"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
[0002]本发明涉及通信技术领域, 特别涉及一种数据边界确定方法、 指示 信息发送方法及其装置。
背景技术
[0003] 随着移动通信技术的发展, 通用移动通讯系统 (UMTS , Universal Mobile Telecommunications System ) 中分别引入了下行非连续接收( DRX, Discontinuous Reception )和多流传输 ( Multiflow )特性, 但是, DRX 和 Multiflow的共存问题, 是目前有待解决的技术问题。
[0004] 目前, 由于不同的信道间存在固定的定时关系, 从小区侧来看, 需 要找到高速专用物理控制信道(HS-DPCCH, High Speed-Dedicated Physial Control Channel )的起点以便接收上行数据, 根据协议规范, 小区需要根据 高速共享控制信道( HS-SCCH, High Speed-Shared Control Channel )起点, 向后找到离 1280 chips的时间上最靠近的 HS-DPCCH边界作为边界。 这里 以 SF-DC特性为例。 在 SF-DC特性中, 有两个服务小区, 彼此间存在一定 的定时差, 并且两个小区可以在同一个基站内或在不同的基站内。
[0005] 由于 SF-DC中 UE下行需要在两个小区接收数据, 但上行只需在一 个小区发送, 另一个小区需要解调数据 (比如在跨基站的 SF-DC场景中 ), 这样需要用户设备 UE ( User Equipment )侧对下行数据接收的子帧进行指 定配对关系。
[0006]可定义 UE的参考小区和辅助小区,参考小区为 UE的下行物理信道 HS-PDSCH和上行物理信道 HS-DPCCH定时差为 19200 chips或 7.5 slot的 小区, 另一个小区则为辅助小区, 或称为非参考小区。 比如 UE参考小区中 的 HS-SCCH S_DRX=0与非参考小区的 HS-SCCH S_DRX=0配对,那么 UE 会在接收了这两个子帧的数据后, 在对应的 HS-DPCCH上同时反馈这两个 子帧的反馈信息, 其中 HS-DPCCH和 HS-SCCH有固定的定时关系。
[0007]但是, 对于参考小区而言, 对其调度的 HS-SCCH S—DRX=0数据子 帧,参考小区按照协议规范中的 "HS-SCCH对应的 CFN— DRX n子帧起点后 1280 chips 的时间上最靠近的 HS-DPCCH 边界"会找到 HS-DPCCH S— DRX=0的子帧为其边界。 需要注意的是, HS-DPCCH S— DRX=0子帧并 不承载 HS-SCCH S_DRX=0子帧的反馈,而要根据固定的定时来找其反馈, 比如下一个 HS-DPCCH S_DRX=0会承载 HS-SCCH S_DRX=0的反馈信息。
[0008] 而对于非参考小区所在的基站, 也会根据协议规范去寻找 HS-DPCCH的边界, 但是, 费参考小区就会找到 HS-DPCCH S—DRX=1 , 但 由于 UE侧是将两个小区的 HS-SCCH S_DRX=0做同时接收, 并且通过一 条 HS-DPCCH 反馈, 因而这样会导致 UE 和非参考小区所在的基站对 HS-DPCCH 信息理解不一致 (也即非参考小区所在的基站错误定位 HS-DPCCH边界 ), 降低了下行数据传输的性能。
[0009]在对现有技术的研究和实践过程中, 本发明的发明人发现, 现有的 实现方式中, 由于非参考小区所在的基站可能无法找到正确的 HS-DPCCH 边界, 从而导致 UE 和非参考小区所在的基站对某个下行数据发送的上行 HS-DPCCH理解不一致, 导致下行数据传输性能下降的技术问题。 发明内容
[0010]本发明实施例中提供了一种数据边界确定方法、 指示数据发送方法 及其装置, 以解决现有技术中非参考小区所在的基站不能找到正确的
HS-DPCCH边界, 导致下行数据传输性能下降的技术问题。
[0011]为解决上述技术问题, 本发明实施例提供一种数据边界确定方法, 所述方法包括: 非参考小区所在的基站获取参考小区的定时信息, 或者获 取用来确定高速专用物理控制信道 HS-DPCCH的边界信息的参数; 所述基 站根据所述参考小区的定时信息或者所述参数确定 HS-DPCCH 的边界信 息。
[0012]本发明实施例还提供一种指示信息发送方法, 所述方法包括: 获取 参考小区的定时信息, 或者用来确定高速专用物理控制信道 HS-DPCCH的 边界信息的参数; 将所述参考小区的定时信息, 或者用来确定高速专用物 理控制信道 HS-DPCCH的边界信息的参数发送给所述非参考小区所在的基 站, 以便于所述非参考小区所在的基站确定 HS-DPCCH的边界信息。
[0013]本发明实施例还提供一种数据边界确定装置, 所述装置包括: 获取 单元, 用于获取参考小区的定时信息, 或者用来确定高速专用物理控制信 道 HS-DPCCH的边界信息的参数; 确定单元, 用于根据所述参考小区的定 时信息或者所述参数确定 HS-DPCCH的边界信息。

[0015] 由上述技术方案可知, 由于所述非参考小区所在的基站可以获得参 考小区的定时信息, 或者用来确定高速专用物理控制信道 HS-DPCCH的边 界信息的参数, 从而可以正确的定位 HS-DPCCH的边界信息, 从而提高了 下行数据传输性能。

[0044]当然, 在上述实施例中, 所述用来确定非连续接收定时信息的参 数也可以包括上述的一种, 或多种, 本实施例不作限制, 当包括多种中, 确定 HS-DPCCH边界信息的方式对应的方式来确定, 具体详见上述, 在 此不再赘述。
[0045]还请参阅图 2 , 为本发明实施例提供的一种指示信息发送方法的 流程图, 所述方法包括:
[0046] 201 : 获取参考小区的定时信息, 或者用来确定高速专用物理控制 信道 HS-DPCCH的边界信息的参数;
[0047]在该步骤中, 网络中的无线网络控制器 (RNC ) 获取的方式有多 种, 比如, 在网络的 RNC为用户设备配置多流传输时, RNC接收到参 考小区所在的基站发送的定时信息, 或者用来确定高速专用物理控制信 道 HS-DPCCH的边界信息的参数; 或者, 网络的 RNC向参考小区所在 的基站发送获取参考小区的定时信息, 或者用来确定高速专用物理控制 信道 HS-DPCCH的边界信息的参数的请求;以及接收所述参考小区发送 包括该参考小区的定时信息, 或者用来确定高速专用物理控制信道 HS-DPCCH的边界信息的参数的响应。
[0048]其中, 在该实施例中, 所述参考小区的定时信息包括: 非连续接 收 DRX定时信息; 但并不限于此, 还可以包括其他的定时信息。
[0049]所述用来确定高速专用物理控制信道 HS-DPCCH 的边界信息的 参数至少包括下述一种: 参考小区与非参考小区的 DRX 定时信息差 A TDRX ; 或者参考小区的非连续接收的偏移量 DRX— OFFSET; 或者参考 小区的上行专用物理控制信道 DPCCH和上行 HS-DPCCH的定时关系; 或者参考小区和非参考小区的 m差值信息 Δηι , 但并不限于此, 还可以 包括用来确定高速专用物理控制信道 HS-DPCCH 的边界信息的其他参 数。
[0050]可选的, 所述参考小区的非连续接收的偏移量 DRX— OFFSET 是 网络通过公式
+ 1.
1 - 2560 计算得到的, 其中, ArDRX为参考小区与非参考小区的
DRX定时信息差。
[0051] 202: 将所述参考小区的定时信息, 或者用来确定高速专用物理控 制信道 HS-DPCCH 的边界信息的参数发送给所述非参考小区所在的基 站, 以便于所述非参考小区所在的基站确定 HS-DPCCH的边界信息。
[0052]其中, 该步骤中, RNC发送给所述非参考小区所在的基站的方式 有多种, 只要发送的消息中包括参考小区的定时信息或者用来确定高速 专用物理控制信道 HS-DPCCH的边界信息的参数即可。 [0053]为了便于本领域技术人员的理解,下面以具体的应用实例来说明,
[0054]在一种实施例中, 以 RNC获取参考小区的 DRX定时信息为例。 [0055]首先, RNC先从参考小区中获取该参考小区的 DRX定时信息(即
A TDRX ), 其获取的方式, 可以主动请求, 也可以是被动接收, 本实施例 不作限制。 其中, 该 DRX定时信息定义为 F-DPCH和 HS-SCCH的定时 偏差, 在该实施例中, 所有的 D XI , TDRX2 ; Δ κχ的单位都是 chip 。
[0056]其中, 在该实施例中, 参考小区可以在每次 RNC为 UE配置多流 传输(Multiflow ) 向 RNC上报该 DRX定时, 可以是周期性上报, 也可 以是实时上报; 当然, 也可以是 RNC要求上报时, 参考小区才将该参考 小区的 DRX定时通知给 RNC。 这是因为, 信道定时是在小区 (基站) 和 UE 间维护, 伴随小区时钟漂移、 空口传输时延变化以及其他因素, 这种 DRX定时信息会随时间的变化而可能改变, 因而, 在该实施例中, RNC侧还要及时更新获取到的 DRX定时信息。
[0057]其次, RNC将所述参考小区的 DRX定时信息通知给非参考小区 所在的基站。
[0058]最后,非参考小区所在的基站根据所述参考小区的 DRX定时信息 确定 HS-DPCCH的边界信息。
[0059]也就是说,当非参考小区所在的基站获知参考小区的 DRX定时信 息后, 首先根据参考小区的 DRXI对应的 F-DPCH找到 HS-SCCH的边界, 如图 3所示, 图 3为本发明实施例中提供的一种通过 DRX定时信息进 行数据边界确定方法的应用实例图。 需要说明的是, 该实施例中的 "HS-SCCH边界信息"可用于非参考小区所在的基站查找 HS-DPCCH定 时所用, 还可用于下行数据传输调度。
[0060]然后, 非参考小区所在的基站通过协议中的规则 "HS-SCCH对应 的 CFN— DRX n子帧起点后 1280 chips的时间上最靠近的 HS-DPCCH边 界信息"查找到 HS-DPCCH的边界, 从而就能保证参考小区和基站找到 相同的 HS-DPCCH边界, 其具体的查找过程对于本领域技术人员来说, 已是公知技术, 在此不再赘述。
[0061]在另一实施例中,网络以将参考小区与非参考小区的 DRX定时信 息差 ATdrx通知给非参考小区所在的基站为例。
[0062]首先, 网络将参考小区的 DRX定时信息差 Δτ。κχ = τ。κχ2τ。^ (以 码片为单位) 通知给非参考小区所在的基站; 需要注意的是, RX有正 负之分,如图 3所示,图中 DRXI为负值,因为 F-DPCH在对应的 HS-SCCH 定时之后, 其中 DRX2为正值, 因为 F-DPCH在对应的 HS-SCCH定时之 前。
[0063]然后,非参考小区所在的基站根据 A Rx和自身 DRX定时信息 进行计算, 得到参考小区的 DRX定时信息 DRX1
[0064]再后,非参考小区所在的基站根据参考小区的 DRXI对应的 F-DPCH 找到 HS-SCCH的边界。
[0065]如图 3所示, 本实施例中的 "HS-SCCH边界"可用于非参考小区所 在的基站找寻 HS-DPCCH定时所用, 还可用于下行数据传输调度。 然后 非参考小区所在的基站通过协议中的规则 "在 HS-SCCH 对应的 CFN— DRX n子帧起点后 1280 chips的时间上最靠近的 HS-DPCCH边界 信息"找到 HS-DPCCH的边界, 从而保证了参考小区和非参考小区所在 的基站找到相同的 HS-DPCCH边界。
[0066]图 3中, 参考小区的 DRX定时信息为 非参考小区所在的基 站的 DRX定时信息为 。非参考小区所在的基站首先找到 S— DRX=0 , 然后找到对应的 F-DPCH的开始边界。 根据上述过程, 非参考小区所在 的基站可以根据^^2和^。^以获得参考小区的 DRX 定时信息 ^。 由 图可见, 非参考小区所在的基站根据协议中定义的 HS-SCCH 和 HS-DPCCH的定时规则, 可以找到 S— DRX=0对应的 HS-DPCCH子帧为 S_DRX=0, 这样可以保证参考小区和非参考小区所在的基站都能有正确 的 HS-SCCH和 HS-DPCCH配对有正确的理解。
[0067]在又一种实施例中, 网络的 RNC还是将参考小区的 DRX定时信 息差

- ^RX!通知给非参考小区所在的基站, 但是, 非参考小区 所在的基站确定 HS-DPCCH和 /或 HS-SCCH的边界的方式不同,具体为: [0068]非 参 考 小 区 所 在 的 基 站 通 过 公 式 : 5*CFN— DRX+

Figure imgf000014_0002
[0069]其中, 上述公式中 I I符号为向上取整, 比如符号内数值为 0.5则计 算结果为 1 , 符号内数值为 1.5 则计算结果为 2 , 以此类推; 所述

为非连续接收的子帧偏移量; 所述 CFN— DRX表示非连续接 收状态下的连接帧号; 所述 S— DRX表示非连续接收状态下的子帧号, 且 CFN— DRX和 S— DRX均为非参考小区的 HS-DPCCH和 /或 HS-SCCH修正 前的值。
[0070]在该实施例中, 上述公式主要用于判定信道的边界; 而下述公式主 要用于 NodeB判定 UE反馈信息 (即 CQI所在的位置)。
[0071]此时, HS-DPCCH发送信道质量指示 (CQI, Channel Quality Indicator) 的时刻为:
AT,
+ 1.
((5*CFN— DRX - UE—DTX—DRX— Offset + S DRX+l - 2560 ) MOD k')
0 with k' = kK2ms)
[0072]其中, k'为 DRX周期对应的子帧数; CFN— DRX为非连续接收状态 下的连接帧号; UE—DTX—DRX— Offset为: 用户设备非连续发射且非连续接 收的偏移量; S— DRX为非连续接收状态下的子帧号; MOD为求模运算。
[0073]进一步地 , 当网络又配置了多输入多输出( MIMO , Multi Input Multi Output ) 时, 在满足上面公式的前提下, 若还满足如下公式:
-^ + l.
5xCFN DRX-UE DTX DRX Offset + S DRX+1 - 2560
3
mod cqi < N_cqi_typeA
[0074]则 UE需要发送类型 A的信道质量指示 (typeA CQI, typeA Channel Quality Indicator ),否则, UE发送 typeB CQI。其中, typeA CQI和 typeB CQI 的定义具体详见 3GPP协议 25.212中的定义, 在此不再赘述; M— cqi和 /或 N— cqi— typeA为网络通过信令发送给 UE的参数。 另外, 该公式中其他的参 数详见上述, 在此不再赘述。
[0075] HS-SCCH接收 CQI的时刻为:
+ 1.
((5*CFN— DRX - UE—DTX—DRX— Offset + S— DRX +1 - 2560 ) MOD
3
UE— DRX cycle) = 0; [0076]其中, 该公式中各个的参数的定义, 具体详见上述对应的参数, 在 此不再赘述。
[0077] 在又一种实施例中, 网络可以将参考小区的非连续接收的偏移量 ( DRX OFFSET )通知给非参考小区所在的基站, 其中, DRX— OFFSET, 但并不限于此
Figure imgf000016_0001
[0078] 而 非 参 考 小 区 所 在 的 基 站 通 过公 式 5*CFN— DRX+ S—DRX+DRX— OFFSET, 得到 HS-DPCCH的边界。
[0079]其中, CFN— DRX和 S— DRX的定义如上所示, 且均为非参考小区修 正前的值。
[0080]那么 , HS-DPCCH发送 CQI的时刻为:
((5*CFN— DRX - UE—DTX—DRX—Offset+S—DRX+DRX— OFFSET) MOD k') = 0, with k' = kK2ms)
[0081]其中 k'为 DRX周期对应的子帧数, 该公式中的其他参数如上所示, 在此不再赘述。
[0082]进一步地, 当网络又配置了 MIMO时, 在满足上面公式的前提下, 若还满足如下公式:
5 X CFN—DRX - UE DTX DRX Offset + S—DRX + DRX _ OFFSET
mod _cqi < N_cqi_typeA k'
[0083]则 UE需要发送 typeA CQI,否则 UE发送 typeB CQI。其中 typeA CQI 和 typeB CQI 在 3GPP 协议 25.212 中有明确定义。 参数 M— cqi 和 /或 N—cqi— typeA为网络通过信令发送给 UE。
[0084] HS-SCCH接收 CQI时刻为: ((5*CFN— DRX - UE—DTX—DRX— Offset + S DRX + DRX— OFFSET) MOD UE DRX cycle) = 0
[0085]在又一种实施例中, 网络的 RNC以将参考小区的上行 DPCCH和上 行 HS-DPCCH的定时关系(称为 m值)通知给非参考小区所在的基站为例, 然后,非参考小区所在的基站根据该定时信息生成 HS-DPCCH的边界信息。
[0086]在该实施例中, RNC先从参考小区中获取该参考小区的 DRX定时 信息(即 A RX ), 其获取的方式, 可以主动请求, 也可以是被动接收, 本实 施例不作限制。 其中, 该 DRX定时信息定义为 F-DPCH和 HS-SCCH的定 时偏差, 在该实施例中, 所有的 D XI , TDRX2 ; Δ κχ的单位都是 chip 。
[0087]在该实施例中, m值为某个下行 HS-SCCH子帧对应的上行 DPCCH 发送边界, 和针对该 HS-SCCH的反馈的 HS-DPCCH边界之间的定时差, 或者可以理解为针对一个 HS-SCCH数据发送的上行 DPCCH和 HS-DPCCH 定时差。 参考小区可以根据 m值找到 HS-DPCCH的边界信息, 从而检测携 带的信息,具体如图 4所示,图 4为本发明实施例中提供的另一种通过 DRX 定时信息进行数据边界确定方法的应用实例图。
[0088] 图 4中, 参考小区可以根据来找到 DRXI , 从而可以建立 HS-SCCH和 HS-DPCCH的关联关系,参考小区可以将 m值通知给非参考小区所在的基 站, m值为上行 DPCCH和 HS-DPCCH的定时偏差, 非参考小区所在的基 站获知参考小区的 m值后, 可以直接推算出 HS-SCCH和 HS-DPCCH的关 联关系, 比如图 4中参考小区找到 HS-SCCH S_DRX=0对应的 HS-DPCCH S_DRX=0, 此时非参考小区所在的基站获知的 m值为 5个 S— DRX, 此时 非参考小区所在的基站可以根据(获取的 m值 -5 )来确定 S— DRX, 此时可 以保证非参考小区所在的基站和参考小区所在的基站理解一致。
[0089]其中, 图 4所述实施例与图 3所述实施例的不同之处在于, 非参考 小区所在的基站获取到的 DRX定时信息不同。 [0090]本实施例中, RNC将参考小区的 m值通知给非参考小区所在的基站, 这样由于两个小区检测到上行 DPCCH的定时是一样的,因而非参考小区所 在的基站可以找到相同的 HS-DPCCH边界。
[0091]在又一种实施例中, 该实施例在上述实施例的基础上, RNC还可 以将参考小区的 F-DPCH和 HS-PDSCH的定时信息、或参考小区和非参 考小区的 m差值信息通知非参考小区所在的基站。
[0092]其中, 将所述参考小区的 F-DPCH和 HS-PDSCH的定时信息通知 给非参考小区所在的基站, 这种方式中, 由于 F-DPCH和 HS-PDSCH的 定时信息和 m值之间有唯一的换算关系, 因而, 最终计算出正确的用于 检测 HS-DPCCH边界。
[0093]另外, 将所述参考小区和非参考小区的 m差值信息通知非参考小 区所在的基站, 这种方式中, 通过非参考小区所在的基站用自身的 m值 和 m差值的计算, 比如通过公式: 256 * Am = A DRX , 最终计算出正确的 用于检测 HS-DPCCH边界的 m值信息。
[0094]也就是说, 实施例六所述的两种方案, 与直接通过参考小区的 m 值判断的效果一样。
[0095]由上述实施例可知,本发明实施例提供将参考小区的 DRX定时信 息或者,用于确定 HS-DPCCH的边界信息的参数通知给非参考小区所在 的基站, 以便于非参考小区所在的基站根据该 DRX 定时信息或者所述 参数对 HS-DPCCH边界的检测, 从而确定 HS-DPCCH边界, 提高了下 行数据传输的性能。 同时也保证了多流传输 (Multiflow ) 中非参考小区 所在的基站对上行数据的成功接收。
