Description

一种处理高速数据传输的方法、 装置及系统 技术领域
本发明涉及无线通信技术领域, 具体是涉及一种处理高速数据传输的方 法, 及相应的装置和系统。 背景技术
在 WCDMA(Wideband Code Division Multiple Access,宽带码分多址)系统 中, 用户设备 ( UE )通过诸如节点 B ( NodeB )之类的基站实现数据传输。
在传输高速数据时, 由于各个 UE相对于 NodeB的位置不同, 通过信道 与 NodeB交互的时间也不同,从而导致在 NodeB的接收机处接收到的信号是 不对齐的, 即各 UE的信号不完全正交, 使得各个 UE的信号相互干扰, 从而 降低了 NodeB的接收性能。
为尽量减小各个 UE之间的信号干扰,目前的一种解决方案是使用同步增 强专用信道 ( SEDCH, Synchronized Enhanced Dedicated Channel ),该方案主要 是通过多个 UE使用相同的扰码、 不同的信道化码来提高 NodeB侧接收信号 的正交性;且该信道化码通常为 OVSF码 (Orthogonal Variable Spreading Factor, 正交扩频码:)。
在实现本发明的过程中, 发明人发现:
该使用 SEDCH的方案能够减少各个 UE之间的信号干扰,但该方案要求 多个 UE使用相同的扰码, 且不同的 UE使用不同的信道化码, 而同一扰码对 应的信道化码数量有限, 这就导致在 UE较多时, 对作为信道化码的 OVSF 码资源的需求较高。 因此,很可能由于 OVSF码资源不足而导致 UE无法传输 高速数据。
发明内容
本发明实施例的目的在于提供一种处理高速数据传输的方法, 以尽量减 小各个 UE间的信号干扰, 且不需要增加对 OVSF码资源的需求。 为解决上述问题, 本发明实施例提供了以下技术方案:
本发明实施例的一种处理高速数据传输的方法, 该方法包括:
为用户设备设置时分复用时序安排, 根据该设置确定用于控制该用户设 备传输高速数据的调度信 , ;
设置用于传输所述调度信息的信道;
将所述调度信息通过所设置的信道发送给所述用户设备。
本发明实施例的一种实现高速数据传输的方法, 该方法包括:
接收网络侧发送的数据;
从所述数据中解析出调度信息;
在所述调度信息表示能够传输高速数据时进行高速数据的传输。
本发明实施例的一种处理高速数据传输的网络侧设备, 该网络侧设备包 括:
时序设置模块, 用于为用户设备设置时分复用时序安排;
调度信息设置模块, 用于根据所述时序设置模块设置的时分复用时序安 排确定用于控制所述用户设备传输高速数据的调度信息;
信道设置模块, 用于设置传输所述调度信息设置模块确定的调度信息的 信道;
发送模块, 用于将所述调度信息设置模块确定的调度信息通过所述信道 设置模块设置的信道发送给所述用户设备。
本发明实施例的一种实现高速数据传输的用户设备, 该用户设备包括: 收发模块, 用于接收网络侧发送来的数据;
解析模块, 用于从所述收发模块接收的数据中解析出调度信息; 高速数据传输模块, 用于在所述解析模块解析出的调度信息表示能够传 输高速数据时, 通过所述收发模块进行高速数据的传输。
本发明实施例的一种处理高速数据传输的系统, 所述系统包括: 网络侧设备, 用于为用户设备设置时分复用时序安排, 根据该设置确定 用于控制该用户设备传输高速数据的调度信息; 设置传输该调度信息的信道; 以及将该调度信息通过上述信道发送给用户设备。
本发明实施例通过为用户设备设置时分复用时序安排, 根据该设置确定 用于控制该用户设备传输高速数据的调度信息, 设置用于传输上述调度信息 的信道, 并将该调度信息通过所设置的信道发送给用户设备, 使得用户设备 能够根据调度信息发送高速数据, 从而使得需要传输高速数据的用户设备所 发送的信号能够保证在时间上基本正交, 从而将用户设备间的信号干扰降到 最低, 进而提高了基站的接收性能。 由于多个用户设备可以使用不同的扰码, 因此对 OVSF码资源没有特殊要求, 也就不会出现因 OVSF码资源不足而导 致用户设备无法传输高速数据的情况。
附图说明

图 3为本发明实施例中 UE实现高速数据传输的流程图;

具体实施方式
为使本发明的目的、 技术方案和优点更加清楚, 下面将结合附图对本发 明作进一步地详细描述。
本发明实施例主要是对传输高速数据的用户进行时分复用的时序安排 ( TDM scheduling, Time Division Multiplex scheduling ) 的设置, 并根据该设 置对传输高速数据的用户在不同的传输时间间隔 ( TTI , Transmission Time Interval )之间进行调度。
该实施例具体来说, 首先需要对 UE进行 TDM scheduling的设置, 根据 该设置为所述 UE确定与所设置的 TDM scheduling相对应的调度信息, 还需 要增设用于传输相应调度信息的信道,之后, 网络侧则可以将为 UE设置的调 度信息通过所设置的信道发送给 UE。
本发明实施例方法可以根据实际需要对各个步骤顺序进行调整。 比如, 在上述过程中,可以是先确定 UE的调度信息, 然后设置用于传输所述调度信 息的信道; 也可以是先设置可传输所述调度信息的信道, 然后将确定了的调 度信息直接在该信道上传输。
相应地, UE 即可根据收到的调度信息确定是否可以进行高速数据的发 送。
上述使得 UE根据调度信息发送高速数据的方案,使得需要传输高速数据 的 UE所发送的信号能够在时间上基本正交,从而将 UE间的信号干扰降到最 低, 进而提高了 NodeB的接收性能。 并且上述实施例中的多个 UE可以使用 不同的扰码, 因此对 OVSF码资源没有特殊要求, 也就不会出现因 OVSF码 资源不足而导致 UE无法传输高速数据的情况。
上述实施例中, 设置调度信息具体可以是设置控制命令值, 在设置控制 命令值时, 可以设置不同的值来表示在接下来的调度颗粒度中是否调度该 UE, 比如, 可以设置 1来表示 UE在下个调度颗粒度中被调度, 0则表示不 被调度。 这样, UE在得到为 1的控制命令值时, 确定本 UE可以传输高速数 据; 在得到为 0的控制命令值时, 则确定本 UE停止传输高速数据。
上述实施例中, 对 UE进行 TDM scheduling的设置, 使得多个 UE可以 在不同的调度周期进行高速数据传输, 该调度的颗粒度可以为 K个 ΤΉ; 通 过设置 K值就可以控制 UE的高速数据发送频率。 K值具体可以由网络侧设 置, 然后通过消息发送给 UE; 也可以预先在 UE侧设置该 K值。 图 1的前两 行对应的是 K值设置为 1的情况下的 TDM方式, 图 1的后两行对应的是 K 值设置为 2的情况下的 TDM方式。
另外, 上述 TTI具体可以根据需要设置。 比如, 可以设置为 2ms, 且每 个 TTI中对应 3个时隙; 还可以设置为 10ms, 每个 TTI中对应 12个时隙。
上述实施例中, 增设用于传输相应调度信息的信道, 具体可以是增设专 用信道, 也可以是增设公共信道。 二者的相同之处, 是都要将调度信息, 即 本实施例中的控制命令值发送给 UE。
如果增设公共信道, 则可以将控制命令值与 UE ID之类的标识一起发送 给 UE, 使得 UE能够获取与本 UE相关的控制命令值。
如果增设专用信道, 则基于该专用信道的具体实现方案如下:
设置专用信道, 并通过使用不同的控制命令值, 以及设置不同的正交序 列来区分发送给不同 UE的信令。 这里, 及后续的实施例中, 以调度信息为控 制命令值为例, 当然, 该调度信息还可以作其他设置。
比如, 可以设置一个新的专用信道, 即增强调度指示信道(E-SICH, Enhanced Scheduling Indicator Channel )。
网络侧在通过该专用信道向 UE发送调度信息时,具体可以根据正交序列 进行发送。 比如, 将用于调度高速数据传输的控制命令值与哈达玛(Hadma ) 序列相乘, 并将得到的数据比特 1¾承载在 E-SICH信道上。 假设控制命令值 为 a, 则该控制命令值与 Hadma序列相乘得到的 1¾可以用下述公式表示:
Figure imgf000007_0001
对于上述处理来说, 以 2ms、 对应 3个时隙的 TTI为例, 在进行控制命 令值与 Hadma 序列相乘的操作时, 其中的每个时隙相乘时所使用的 Css,40,m(i),j可以釆用 hopping (跳跃)的方式确定, 比如, 可以釆用下述表 1 所示的模式。 如果是对应 12个时隙的 TTI, 则按照前一种 TTI的处理方式重 复 4次即可。 这里以釆用控制命令值与 Hadma序列相乘, 且釆用 hopping方 式为例, 显然釆用其他类似方式也可以, 只要能够达到对控制命令值进行数 据处理的目的即可。

表 1
之后,网络侧需要将 E-SICH信道上的数据与承载在其他专用信道上的数 据进行处理, 形成无线信号并发送出去。 其中, 其他信道可以是诸如增强相 对 4受权信道 ( E-RGCH, Enhanced Relative Grant Channel )和增强混合重传指 示信道( E-HICH, Enhanced Hybrid ARQ Indicator Channel )之类的专用信道, 这种情况下的处理如图 2所示。 该处理具体可以包括:
步骤 A、将承载在 E-SICH信道上的数据比特与其他信道上的数据进行数 据合并操作, 具体可以是加法操作。 步骤 B、 将步骤 A合并后的数据与网络侧分配给该 UE的 OVSF码进行 扩频处理, 具体可以是乘法操作。
步骤 C、 将扩频后的数据处理成无线信号并发送, 其中, 该处理具体可 以包括加扰、 脉冲成型等。 相应地, UE在收到无线信号之后, 通过对无线信号的处理, 则会得到网 络侧发送来的控制命令值。以前述的控制命令值设置为例,如果得到的值为 1 , 则表示在接下来的 K个 TTI, 该 UE可以进行高速数据的传输; 否则, 该用户 不能进行高速数据的传输。
另外, UE可能并不是一直保持高速数据的传输, 比如, 可能是在某个时 间段持续进行高速数据的传输, 在另一个时间段, 则改为低速数据的传输; 或者反之。 针对这种情况, 可以在初始建立设置时, 不考虑 UE当前传输的是 高速数据还是低速数据, 直接为每个能够传输高速数据的 UE设置正交序列。
当然, 为节约正交序列的资源, 还可以进一步在设置了专用信道之后, 在网络侧设置一个正交序列的资源池, 在网络侧确定 UE在传输高速数据时, 从该正交序列资源池中为该 UE选择正交序列,并将该正交序列的相关信息发 送给该 UE。
在设置正交序列资源池后, 还可以对该资源池中的正交序列进行编号指 示, 并先从该资源池中选择一个序列子集, 将该序列子集先通过广播方式发 送给 UE。 之后, 在网络侧确定该 UE传输高速数据时, 则从该序列子集中为 该 UE选择正交序列,并将该正交序列的编号发送给该 UE。在发送该编号时, 具体可以使用高速共享控制信道( HS-SCCH , High Speed Physical Downlink Shared Control Channel ) 的 order命令进行发送。
这样,针对设置正交序列资源池的方案,如果网络侧发现某个 UE在传输 高速数据, 则可以由 NodeB通过上述两种方式告知该 UE当前使用的正交序 列。 控制命令值则可以随其他数据一起发送给 UE。 这样, UE在获得控制命 令值和正交序列后, 则可以进行正常的调度过程。
另外, 网络侧除了可以向 UE发送分配给该 UE的正交序列的相关信息, 还可以向 UE发送禁止该 UE使用该正交序列的命令。 且该命令也可以通过 HS-SCCH信道的 order方式发送, 当然也可以釆用其他方式发送。
上述实施例通过为 UE设置 TDM scheduling, 确定与所设置的 TDM scheduling相应的用于控制该 UE传输高速数据的调度信息, 设置用于传输该 调度信息的信道, 并将该调度信息通过所设置的信道发送给该 UE, 使得 UE 能够根据调度信息发送高速数据,从而使得需要传输高速数据的 UE所发送的 信号能够保证在时间上基本正交,将 UE间的信号干扰降到最低,进而提高了 基站的接收性能。
另外, 本发明实施例中设置正交序列资源池的方案, 可以进一步节约正 交序列资源, 有效避免正交资源浪费的问题。
基于上述针对网络侧的设置,本发明实施例的 UE侧, 即可实现高速数据 的传输, 具体实现如图 3所示, 对应如下步骤:
步骤 301、 UE接收网络侧发送来的数据;
步骤 302、 UE从所接收到的数据中解析出网络侧发送的调度信息; 步骤 303、根据解析出的调度信息确定本 UE当前是否可以进行高速数据 传输, 即网络侧当前是否给本 UE分配 K个 TTI以进行高速数据的传输, 如 果是, 则进行高速数据传输, 否则, 不进行高速数据的传输。
如前所述, 所述解析出的调度信息可以是控制命令值, 该控制命令值的 具体情况在此不再赘述。
如果网络侧通过设置公共信道发送调度信息给 UE, 则上述步骤 302中, UE从公共信道发送来的数据中获取发送给本 UE的数据, 并从所获取的数据 中得到所述调度信息。网络侧可以在通过公共信道发送的数据中携带该 UE的 ID等标识, 这样 UE则可以根据标识确定公共信道中属于本 UE的数据。
如果网络侧通过设置专用信道发送调度信息给 UE, 则上述步骤 302中, UE对通过专用信道发送来的数据进行逆运算, 获取发送给本 UE的数据, 并 从中获取调度信息。 具体地, UE具体需要对通过专用信道发送来的无线信号 进行解扰、 解扩频及解合并, 并根据正交序列对所设置的专用信道上传输的 数据进行相乘的逆运算, 得到该调度信息。
这里 UE所使用的正交序列可以是网络侧发送给本 UE的, 当然也可以是 通过其他方式获取的。 比如, 如果为每个 UE都配置了正交序列, 则 UE可以 直接从本设备中获取该正交序列。
对于所述正交序列是由网络侧发送给本 UE 的, 且网络侧如前所述的情 况, 如果网络侧是直接将正交序列的相关信息发送给本 UE, 则本 UE可以根 据该相关信息确定相应的正交序列; 如果网络侧是先发送正交序列的序列子 集给 UE, 并在 UE传输高速数据时, 将正交序列的编号发送给 UE, 则 UE获 取该编号后, 直接从收到的正交序列子集中确定相应的正交序列。
上述实施例的 UE从接收到的数据中解析出网络侧发送的调度信息 ,根据 调度信息确定本 UE当前是否可以进行高速数据传输,并根据确定结果进行传 输,从而使得需要传输高速数据的 UE所发送的信号能够保证在时间上基本正 交, 将 UE间的信号干扰降到最低, 进而提高了基站的接收性能。
本发明实施例还提供了处理高速数据传输的网络侧设备, 该网络侧设备 用于为 UE设置 TDM scheduling,根据该设置确定用于控制该 UE传输高速数 据的调度信息; 还用于设置传输该调度信息的信道, 以及将该调度信息通过 该信道发送给 UE。
该网络侧设备具体如图 4所示, 包括时序设置模块 41、 调度信息设置模 块 42、 信道设置模块 43和发送模块 44。 其中,
时序设置模块 41 , 用于为 UE设置 TDM scheduling;
调度信息设置模块 42, 用于确定与所述时序设置模块 41 设置的 TDM scheduling相应的用于控制所述 UE传输高速数据的调度信息;
信道设置模块 43 ,用于设置传输所述调度信息设置模块 42确定的调度信 息的信道;
发送模块 44,用于将所述调度信息设置模块 42确定的调度信息通过所述 信道设置模块 43设置的信道发送给 UE。
上述调度信息设置模块 42, 具体可以根据所述时序设置模块 41 设置的 TDM scheduling为所述 UE设置控制命令值; 也就是说, 为 UE设置的调度信 息是控制命令值。
上述信道设置模块 43 , 具体可以是设置专用信道, 也可以是设置公共信 道。
如果是设置专用信道, 则发送模块 44需要将调度信息与为该 UE设置的 正交序列相乘, 将得到的数据承载在该专用信道上, 并将承载在该专用信道 和其他专用信道上的数据进行合并、 扩频等处理, 形成无线信号, 并发送给 UE。
对于设置专用信道来传输调度信息的方案来说, 为尽量节约正交序列资 源, 还可以设置正交序列资源池。 具体来说, 可以是在网络侧设备中进一步 包括正交序列设置模块, 用于设置正交序列资源池, 该模块还用于在确定该 UE传输高速数据时, 从该正交序列资源池中为该 UE选择正交序列, 并将该 正交序列发送给发送模块 44。 该正交序列设置模块还用于将为该 UE选择的 正交序列的相关信息通过发送模块 44发送给该 UE。
另外, 该正交序列设置模块还可以是, 用于设置正交序列资源池, 并从 该正交序列资源池中选择一个序列子集, 将该序列子集通过发送模块 44广播 给 UE; 还用于在确定该 UE传输高速数据时, 从该序列子集中为该 UE选择 正交序列, 以及利用 HS-SCCH信道的 order命令将该正交序列的编号通过发 送模块 44发送给该 UE。
上述实施例通过为 UE设置 TDM scheduling, 确定与所设置的 TDM scheduling相应的用于控制该 UE传输高速数据的调度信息, 设置用于传输该 调度信息的信道, 并将该调度信息通过所设置的信道发送给该 UE, 使得 UE 能够根据调度信息发送高速数据,从而使得需要传输高速数据的 UE所发送的 信号能够保证在时间上基本正交,将 UE间的信号干扰降到最低,进而提高了 基站的接收性能。
另外, 本发明实施例中设置正交序列资源池的方案, 可以进一步节约正 交序列资源, 有效避免正交资源浪费的问题。 本发明实施例还提供了实现高速数据传输的 UE, 该 UE接收网络侧发送 来的数据, 并从数据中解析出网络侧发送给该 UE的调度信息,还用于根据解 析出的调度信息确定网络侧为本 UE设置的高速数据传输时间,以及根据该时 间进行高速数据的传输。具体来说, UE如果根据调度信息确定在未来的 K个 ΤΉ的时间内能够进行高速数据的传输, 则进行高速数据传输; 如果确定在未 来的 K个 ΤΉ的时间内应停止高速数据的传输, 则不进行高速数据传输, 如 果之前在传输高速数据, 则停止传输该高速数据。
该 UE的结构如图 5所示, 包括收发模块 51、 解析模块 52及高速数据传 输模块 53。 其中, 收发模块 51 , 用于接收网络侧发送来的数据。
解析模块 52,用于从所述收发模块 51收到的数据中解析出网络侧发送给 本 UE的调度信息。
高速数据传输模块 53 ,则用于根据所述解析模块 52解析出的调度信息确 定本 UE当前是否能够进行高速数据的传输,如果能够进行高速数据传输, 则 通过所述收发模块 51进行高速数据传输; 否则, 不进行高速数据的传输。 当 然, 如果 UE正在进行高速数据传输, 则停止当前高速数据的传输。
如果网络侧是通过设置的公共信道发送包括调度信息的数据, 则收发模 块 51接收的是网络侧通过该公共信道发送的包括调度信息的数据;
相应地, 解析模块 52 则用于从公共信道发送来的数据中获取发送给本 UE的数据, 以及从所获取的数据中得到该调度信息。 如前所述, 具体可以是 网络侧将 UE的 ID等标识和数据一起发送,解析模块 52则根据标识确定该数 据是否为本 UE的数据。
如果网络侧是通过设置的专用信道发送包括调度信息的数据, 则收发模 块 51接收的是网络侧通过该专用信道发送的包括调度信息的无线信号;
相应地,解析模块 52则用于对通过专用信道发送来的无线信号进行解扰、 解扩频及解合并等处理, 并根据正交序列对所设置的专用信道上传输的数据 进行相乘的逆运算, 得到相应的调度信息。 上述实施例的 UE从接收到的数据中解析出网络侧发送的调度信息 ,根据 调度信息确定本 UE当前是否可以进行高速数据传输,并根据确定结果进行传 输,从而使得需要传输高速数据的 UE所发送的信号能够保证在时间上基本正 交, 从而将 UE间的信号干扰降到最低, 进而提高了基站的接收性能。
本发明实施例还提供了一种实现高速数据传输的系统, 该系统包括网络 侧设备和 UE , 其中, 网络侧设备用于为 UE设置 TDM scheduling , 确定与所 设置的 TDM scheduling相应的用于控制该 UE传输高速数据的调度信息; 设 置传输该调度信息的信道; 以及将该调度信息通过设置的信道发送给 UE;

该系统中的网络侧设备和 UE的具体结构如图 4和图 5所示,具体描述如 前所述, 这里不再赘述。
上述实施例通过为 UE设置 TDM scheduling, 确定与所设置的 TDM scheduling相应的用于控制该 UE传输高速数据的调度信息, 设置用于传输该 调度信息的信道, 并将该调度信息通过所设置的信道发送给该 UE, UE则从 接收到的数据中解析出网络侧发送的调度信息,并根据调度信息确定本 UE当 前是否可以进行高速数据传输, 并根据确定结果进行传输, 从而使得需要传 输高速数据的 UE所发送的信号能够保证在时间上基本正交,将 UE间的信号 干扰降到最低, 进而提高了基站的接收性能。
虽然通过参照本发明的某些优选实施方式, 已经对本发明进行了图示和 描述, 但本领域的普通技术人员应该明白, 可以在形式上和细节上对其作各 种改变, 而不偏离本发明的精神和范围。
