而在 LTE-Advanced中, 支持载波聚合 ( Carrier aggregation ), 包括 可达 100MHz。 因此, 用户终端可以被配置 1〜5个分量载波(component carrier ), 同时, 为了使 LTE-A兼容 LTE, 每个载波应能够配置成与 LTE 后向兼容的载波, 因此, 每个分量载波带宽不超过 20M。 这增加了数据 传输带宽, 同时, 使基站对用户终端的上行数据传输的调度具有更大的 灵活性成为可能,但尚缺乏支持 LTE-A系统的载波聚合条件的资源调度 技术方案。 发明内容
针对上述 LTE-A系统中,对载波聚合条件下的多个分量载波缺乏有 效灵活的资源调度技术方案的问题, 本发明提出了适用于载波聚合的 应用场景下的无线网络中的基站和用户终端的数据传输调度方法和 装置。

根据本发明的再一个实施例,提供了一种在无线网络的用户终端
中的上行传输装置, 所述用户终端被配置了一个或多个半静态调度传 输以及一个或多个分量载波, 其中, 一个半静态调度传输仅被配置于 一个分量载波之上, 该上行传输装置包括: 信令接收模块用于接收物 理下行控制信道信令; 资源定位模块连接于信令接收模块, 获取来自 信令接收模块的信息, 用于确定所述信令所指示的无线资源所在的分 量载波; 传输模块连接于资源定位模块, 获取经资源定位模块分析处 理的资源定位信息。 传输模块作为该装置的输出模块, 用于根据信令 的基于的小区无线网络临时标识, 在相应的分量载波指示的无线资源 上执行与小区无线网络临时标识相应的上行传输。在一些实施例的应 用场景的描述中, 所谓的动态传输或半静态调度传输, 也包括其重传 输。 上述的信令接收模块负责监测的监视集 ( monitoring set ) 为该用 户终端被配置用以接收接收物理下行控制信道信令的分量载波的集 合 /组。该装置在同一个分量载波执行动态传输或半静态调度传输及其 可能发生的重传输。

以下结合附图对本发明的具体实施例进行详细的示例性描述。 图 1示出了根据本发明的一实施例的基站 2和用户终端 1构成的 执行上行传输调度的无线网络系统, 其中, 基站 2和用户终端 1之间 根据需要还可以包括中继站 (未在图中示出) 等设备。
图 2示出了根据本发明的一实施例的在无线网络的用户终端 1中 的上行传输方法。
首先在步骤 S201中,用户终端 1接收物理下行控制信道信令(该 信令位于图 1中的用户终端 1和基站 2之间的信道上,图 1中未示出)。
然后, 在步骤 S202中, 用户终端 1确定信令所指示的无线资源 所在的分量载波。
接着, 在步骤 S203 中, 用户终端 1根据信令基于的小区无线网 络临时标识, 在分量载波的指示的无线资源上执行与小区无线网络临 时标识对应的上行传输。
具体地, 步骤 S202可以是: 将承载所述物理下行控制信道信令 的分量载波确定为该信令所指示的无线资源所在的分量载波; 或者, 根据信令中包含的载波指示域确定该信令所指示的无线资源所在的 分量载波。
图 3示出了根据本发明的一实施例的在无线网络的基站 2中用于 用户终端 1 中的上行传输调度方法, 包括步骤 S301 : 发送基于小区 无线网络临时标识的物理下行控制信道信令(位于图 1中的用户终端 1和基站 2之间的信道上, 图 1中未示出:),基站 2与用户终端 1之间 有默认协议约定: 基站 2对该信令的发送时所选择用以承载该信令的 分量载波, 即是基站 2指示的无线资源所在的分量载波, 该载波用以 承载用户终端执行相应的上行传输, 或者, 该信令内容中包含有指示 用户终端执行上行传输的无线资源所在的分量载波的信息。 因此该步
骤 S301可以进一步具体为: 基站 2使用该基站 2所确定的用以承载 执行所述物理下行控制信道信令所基于的小区无线网络临时标识对 应的传输的分量载波,来承载发送所述物理下行控制信道信令;或者, 基站 2发送基于小区无线网络临时标识的带有载波指示域的物理下行 控制信道信令。
图 4示出了根据本发明的一实施例的用户终端 1的分量载波和半 静态调度传输的配置示意图。 用户终端 1 被配置了四个分量载波: CC1、 CC2、 CC3、 CC4, 上述分量载波的带宽可以根据应用场景不同 而不同, 每个载波各自的大小不超过 20M, 本实施例中, 四个分量载 波带宽均配置为 20M。 其中, 用户终端的分量载波 CC1上被配置了 一个半静态调度传输 SPS 1 ,对应的标识为: SPS C-RNTI1 ( Cell Radio Network Temporary Identifier, 未在图中示出), 用户终端的分量载波 CC2 上被配置了一个半静态调度传输 SPS2 , 对应的标识为: SPS C-RNTI2 (未在图中示出)。 根据本发明的另外一个实施例, 半静态 调度传输 SPS1和半静态调度传输 SPS2还可以共享一个公共的半静 态调度小区无线网络临时标识 Common SPS C-RNTI。
基站 2配置用户终端在分量载波 CC1、 CC2、 CC3、 CC4上接收 PDCCH信令, 此处, 分量载波 CC1、 CC2、 CC3、 CC4被称为用户 终端 1 的一个监视集 (monitoring set )。 同时, 用户终端 1被基站 2 调度在分量载波 CC1、 CC2、 CC3上的资源上执行动态传输 DS, 该 动态传输 DS未在图 4中明确示出, 仅在图中以分量载波 CC1、 CC2、 CC3上的 DS1、 DS2、 DS3表示动态传输 DS被基站 2调度而分别发 生在分量载波 CC1、 CC2、 CC3上的情况。 动态传输 DS被标准的小 区无线网络临时标识 normal C-RNTI统一标识。 动态传输 DS或者被 配置的半静态调度传输 SPS1 , 与其各自的潜在的重传输, 通常被同 一个分量载波承载; 对于动态传输 DS 以及配置的半静态调度传输 SPS2亦是如此。
其中, 无线资源 (Resource Block ) RB1 K RB12 位于分量载波 CC1上,无线资源 RB21、RB22位于分量载波 CC2上,无线资源 RB31、
RB32位于分量载波 CC3上, 无线资源 RB41、 RB42、 RB43位于分 量载波 CC4上。
图 5示出了根据本发明的一实施例的用户终端被调度在分量载波 CC1或 CC2上发生的动态传输 DS以及配置的半静态调度传输 SPS1 , SPS2发生的时序关系示意图。
其中,半静态调度传输 SPS1被配置时间点可以是 T。SPS , T, SPS , T2 SPS ...... , 半静态调度传输 SPS1 重传发生的时间点可以是
TSPS Retran ° 半静态调度传输 S P S 2被配置时间点可以是与上述半静态 调度传输 SPS1的被配置时间点不同的: To SPS,, T1 SPS,, T2 SPS' ... .. .
(为简明起见, 未在图 5中示出), 半静态调度传输 SPS2重传发生的 时间点可以是 TSPSJ etran, (为简明起见, 未在图 5中示出)。
动态传输 DS所被调度发生的时间点是: t1 DS , t2 DS , t3 DS。 当 在 t2 DS时刻发生的动态传输, 例如当在分量载波 CC1、 CC2或 CC3 上执行的动态传输 DS1、 DS2、 DS3 , 没有被基站 2接收成功时, 用 户端 1 可能需要进行的上行同步重传输所在的时间点为: tDS— retran , 而 tNACK则是基站 2未成功接收上述动态传输(例如在分量载波 CC1、 CC2或 CC3上执行的动态传输 DS1、 DS2、 DS3 ) 时向终端用户 2发 送 NACK信号所在的时间点。 同样, 当在 t。 SPS时刻发生的半静态调 度传输, 例如静态调度传输 SPS1 , SPS2, 没有被基站 2接收成功时, 用户终端 1 可能需要进行的上行同步重传输所在的时间点为:
TSPS_retran ' 而基站 2未能成功接收配置的半静态调度传输, 例如静态 调度传输 SPS 1 , SPS2时, 向终端用户 2发送 NACK信号所在的时间 点为: TNACK 。
图 6 为根据本发明的一实施例的物理下行控制信道(PDCCH ) 帧结构示意图, 下面结合图 4、 图 5、 图 6对图 2中的无线网络的用 户终端中的上行传输方法进行详细说明。
用户终端 1的分量载波 CC2上配置有半静态调度传输 SPS2, 在 资源 RB21上执行。用户终端 1的分量载波 CC1上配置有半静态调度 传输 SPS 1 , 在资源 RB 11上执行, 其半静态调度传输的一个配置时间
点是 TQ sps, 在每次 T。 SPS时刻之前, 用户终端 1监测其监视集的分 量载波上可能到来的的下行控制信令, 在接收到基于上述半静态调度 传输 SPS1和半静态调度传输 SPS2的物理下行控制信道信令 6 (位于 图 1中的用户终端 1和基站 2之间的信道上, 图 1 中未示出)后, 根 据该物理下行控制信道信令 6以动态传输取代配置的半静态调度传输 SPS1和 /或 SPS2,或者在新指定的无线资源上继续执行半静态调度传 输或其重传输。
用户终端 1保持对监视集中分量载波上的下行信令的监测, 一般 情况下, 用户终端 1在每次 T0 SPS时刻到来之前 t ( A t可因系统而 异, 本实施例中根据上行 HARQ同步传输协议, 可取值为 4ms ), 根 据本发明一实施例, 首先, 执行步骤 S201 , 在分量载波 CC1上接收 到来自基站 2的物理下行控制信道(PDCCH )信令 6, 且该信令基于 半静态调度小区无线网络临时标识 SPS C-RNTIU
此实施例中, 所谓基于半静态调度小区无线网络临时标识 SPS C-RNTI1的物理下行控制信道信令,这里是指的半静态调度小区无线 网络临时标识 SPS C-RNTI1的信息已被都隐含在 PDCCH信令的 CRC 校验位里。 相对地, 用户终端 1接收 PDCCH信令时, 就结合其所配 置的半静态调度传输的半静态调度小区无线网络临时标识 S P S C-RNTI1和循环冗余校验码进行解掩码, 即可判断该 PDCCH信令是 否是发给本用户终端的。
其次, 在步骤 S202中, 用户终端 1处理步骤 S201中接收到的信 令, 该信令由分量载波 CC1承载发送, 因此, 用户终端 1将分量载 波 CC1 确认为信令所指示的无线资源所在的分量载波, 同时, 用户 终端 1处理该信令以获得信令中的无线资源域 RB— DATA, 根据上述 分量载波 CC1和信令中的无线资源域 RB— DATA, 可定位信令所指示 的无线资源为: 无线资源 RB12。
然后, 在步骤 S203 中, 如果信令是基于半静态调度小区无线网 络临时标识, 且该半静态调度小区无线网络临时标识对应一半静态调 度传输 SPS1 , 则在指示的无线资源 RB12上执行该半静态调度传输
SPS1 , 其中, 所述用户终端被配置了多个分量载波, 指示的资源所在 的所述分量载波 CC1 , 与半静态调度传输所配置的分量载波 CC1 相 同, 当然也可以不同, 比如信令指定半静态调度传输 SPS1在 CC2的 RB22上执行。
因此, 根据半静态调度小区无线网络临时标识 SPS C-RNTI1 , 用 户终端 1在 T。SPS时刻, 在分量载波 CC1的无线资源 RB12上执行标 识 SPS C-RNTI1所对应的半静态调度传输 SPS1被配置的传输。
根据本发明的另一实施例, 在步骤 S201 中, 用户终端 1也可以 在分量载波 CC4上接收到来自基站 2的物理下行控制信道( PDCCH ) 信令 6 , 且该信令基于半静态调度小区无线网络临时标识 SPS C-RNTIU
在步骤 S202中, 用户终端 1处理步骤 S201中接收到的信令, 该 信令由分量载波 CC4承载发送, 因此, 用户终端 1将分量载波 CC4 确认为信令所指示的无线资源所在的分量载波, 同时, 用户终端 1处 理该信令以获得信令中的无线资源域 RB— DATA, 根据上述分量载波 CC4和信令中的无线资源域 RB— DATA, 可定位信令所指示的无线资 源为: 无线资源 RB41。
然后, 在步骤 S203 中, 根据半静态调度小区无线网络临时标识 SPS C-RNTI1 , 用户终端 1在 T。SPS时刻, 在分量载波 CC4的无线资 源 RB41上执行标识 SPS C-RNTI1所对应的半静态调度传输 SPS1被 配置的传输。 并且, 本领域技术人员应当理解: 此时, 如果在 T0 SPS 时刻分量载波 CC4上恰好也需要被调度执行动态传输 DS, 则在本实 施例中,该将被调度发生于分量载波 CC4上的动态传输 DS应当被中 止。
根据本发明的另一实施例, 在步骤 S201 中, 用户终端 1在分量 载波 CC4上接收到来自基站 2的物理下行控制信道 ( PDCCH )信令 6, 且该信令基于半静态调度小区无线网络临时标识 SPS C-RNTI1 , 该信令中包含载波指示域 CIF, 该信息指示的分量载波为 CC3。
在步骤 S202中, 用户终端 1处理步骤 S201中接收到的信令, 用
户终端 1根据 CIF的指示信息, 将承载该信令的分量载波 CC3确认 为信令所指示的无线资源所在的分量载波, 同时, 用户终端 1处理该 信令以获得信令中的无线资源域 RB— DATA, 根据上述分量载波 CC3 和信令中的无线资源域 RB—D ATA,可定位信令所指示的无线资源为: 无线资源 RB31。
然后, 在步骤 S203 中, 根据半静态调度小区无线网络临时标识 SPS C-RNTI1 , 用户终端 1在 T。SPS时刻, 在分量载波 CC3的无线资 源 RB31上执行标识 SPS C-RNTI1所对应的半静态调度传输 SPS1被 配置的传输。
根据本发明的另一实施例, 用户终端 1所配置的半静态调度传输 SPS1 和 SPS2 共享一个公共的半静态调度小区无线网络临时标识 Common SPS C-RNTI, 且半静态调度传输 SPS1和 SPS2分别被—— 对应地配置于分量载波 CC1和 CC2上。
在步骤 S201 中, 根据公共的半静态调度小区无线网络临时标识 Common SPS C-RNTI, 用户终端 1在分量载波 CC4上接收到来自基 站 2的物理下行控制信道( PDCCH )信令 6, 该信令中包含载波指示 域 CIF, 该信息指示的分量载波为 CC1。
在步骤 S202中, 用户终端 1处理步骤 S201 中接收到的信令, 用 户终端 1根据 CIF的指示信息, 将承载该信令的分量载波 CC1确认 为信令所指示的无线资源所在的分量载波, 同时, 用户终端 1处理该 信令以获得信令中的无线资源域 RB— DATA, 根据上述分量载波 CC1 和信令中的无线资源域 RB— DATA ,可定位信令所指示的无线资源为: 无线资源 RB12。
然后, 在步骤 S203中, 用户终端 1判断: 分量载波 CC1上配置 有一个半静态调度传输 SPS1。 用户终端 1在1^^时刻, 在分量载波 CC1的无线资源 RB12上执行半静态调度传输 SPS1被配置的传输。
此处, 本领域技术人员应该理解: 步骤 203 中对无线资源 RB12 的具体定位, 和步骤 S203中, 分量载波 CC1上是否配置有一个半静 态调度传输, 这两个技术特征之间无时序的限制, 即: 亦可先判断分
量载波 CC1上是否配置有一个半静态调度传输, 再对无线资源 RB12 的在分量载波 CC1进行具体定位。

其次, 在步骤 S202中, 用户终端 1处理步骤 S201中接收到的信 令, 该信令由分量载波 CC1承载发送, 因此, 用户终端 1 将分量载 波 CC1 确认为信令所指示的无线资源所在的分量载波, 同时, 用户 终端 1处理该信令以获得信令中的无线资源域 RB— DATA, 根据上述 分量载波 CC1和信令中的无线资源域 RB—DATA, 可定位信令所指示 的无线资源为: 无线资源 RB12。
然后, 如果所述信令是基于标准的小区无线网络临时标识, 在步 骤 S203中, 如果用户终端确定: 分量载波 CC1上配置有一半静态调 度传输 SPS1,则在指示的无线资源 RB12上以标准的小区无线网络临 时标识所对应的在分量载波 CC1上执行的动态传输 DS1取代配置的 半静态调度传输 SPS1。
具体地, 用户终端 1 判断: 分量载波 CC1 上配置有一个半静态 调度传输 SPS1。 根据标准的小区无线网络临时标识 Normal C-RNTI, 用户终端 1在 T。SPS时刻, 在分量载波 CC1的无线资源 RB12上执行 标识 Normal C-RNTI 所对应的在分量载波 CC1 上执行的动态传输 DS1 , 而取消在此时刻的半静态调度传输 SPS1的传输。
根据本发明的另一实施例, 在步骤 S201 中, 用户终端 1在分量 载波 CC4上接收到来自基站 2的物理下行控制信道 ( PDCCH )信令 6, 且该信令基于标准的小区无线网络临时标识 Normal C-RNTI, 该

然后, 在步骤 S203中, 用户终端 1判断: 分量载波 CC1上配置 有一个半静态调度传输 SPS1。 则用户终端 1在 TQ SPS时刻, 在分量载 波 CC1的无线资源 RB12上执行标识 Common SPS C-RNTI所对应的 在分量载波 CC1上执行的半静态调度传输 SPS1。
此处, 本领域技术人员应该理解: 步骤 203 中对无线资源 RB12 的具体定位, 和步骤 S203中, 分量载波 CC1上是否配置有一个半静 态调度传输, 这两个技术特征之间无时序的限制, 即: 亦可先判断分 量载波 CC1上是否配置有一个半静态调度传输, 再对无线资源 RB12 的在分量载波 CC1进行具体定位。
根据本发明另一实施例, 在步骤 S201 中未接到任何有效的基于 标识 Common SPS C-RNTI、 SPS C-RNTI SPS C-RNTI2或 Normal C-RNTI的信令,则用户终端继续在其被配置的时间点: T。SPS T1 SPS T2 SPS上以其配置的资源执行其配置的半静态调度传输 SP S 1。

然后, 在步骤 S203中, 用户终端 1判断: 分量载波 CC1上配置 有一个半静态调度传输 SPS1, 且正在处于等待重传状态。 用户终端 1 在 Tsps retran时刻,在分量载波 CCl的无线资源 RB12上执行半静态调 度传输 SPS1的重传输。
此处, 本领域技术人员应该理解: 步骤 203 中对无线资源 RB12 的具体定位, 和步骤 S203中, 分量载波 CC1上是否配置有一个半静 态调度传输以及是否处于等待重传输的状态, 这两个技术特征之间无 时序的限制, 即: 亦可先判断分量载波 CC1 上是否配置有一个半静 态调度传输, 再对无线资源 RB12的在分量载波 CC1进行具体定位。
根据本发明的另一实施例, 用户终端 1依然在: TNACK 时刻接收 到基站 2的接收失败消息, 或者未有回应消息, 则用户终端 1在监测 状态下, 等待重传。
根据本发明一实施例, 首先, 执行步骤 S201, 在分量载波 CC1 上接收到来自基站 2的物理下行控制信道(PDCCH)信令 6, 且该信 令基于标准的小区无线网络临时标识 Normal C-RNTL
其次, 在步骤 S202中, 用户终端 1处理步骤 S201 中接收到的信 令, 该信令由分量载波 CC1承载发送, 因此, 用户终端 1将分量载 波 CC1 确认为信令所指示的无线资源所在的分量载波, 同时, 用户 终端 1处理该信令以获得信令中的无线资源域 RB— DATA, 根据上述 分量载波 CC1和信令中的无线资源域 RB— DATA, 可定位信令所指示 的无线资源为: 无线资源 RB12。
然后, 在步骤 S203中, 用户终端 1判断: 分量载波 CC1上配置 有一个半静态调度传输 SPS1且在等待重传,则用户终端 1在 TSPS— retran 时刻, 在分量载波 CC1 的无线资源 RB12上执行标识 SPS C-RNTI1 所对应的半静态调度传输 SPS1的重传输。
可选地, 如果步骤 S201 中接收到的信令中还包含指示是否执行 所述重传输的信息, 例如新数据指示 NDI; 如果所述信令中包含该指
示执行所述重传输的信息, 则在信令指示的无线资源上执行所述半静 态调度传输的重传输。 具体地, 在上述步骤 S203 中, 如果信令是基 于标准的小区无线网络临时标识, 并且分量载波 CC1 上配置有一半 静态调度传输 SPS1在等待重传, 信令中还包含指示是否执行所述重 传输的信息, 例如上述的新数据指示 NDI; 则如果信令中包含指示执 行所述重传输的信息, 则在所述信令指示的无线资源上执行所述半静 态调度传输 SPS1 的重传输。 具体地, 用户终端可进一步判断信令中 的信息: 新数据指示 NDI,如果新数据指示 NDI内容为指示用户终端 1进行重传, 则用户终端 1在分量载波 CC1的无线资源 RB12上执行 标识 SPS C-RNTI1所对应的半静态调度传输 SPS1的重传输。 如果新 数据指示 NDI内容为指示用户终端 1进行新数据传输, 则用户终端 1 在分量载波 CC1的无线资源 RB12上启动一次新的动态传输, 例如: 在分量载波 CC1上执行的动态传输 DS1。
根据本发明的另一实施例, 在步骤 S201 中, 用户终端 1在分量 载波 CC4上接收到来自基站 2的物理下行控制信道 ( PDCCH )信令 6, 且该信令基于标准的小区无线网络临时标识 Normal C-RNTI, 该 信令中包含载波指示域 CIF, 该信息指示的分量载波为 CC1。
在步骤 S202中, 用户终端 1处理步骤 S201 中接收到的信令, 用 户终端 1根据 CIF的指示信息, 将承载该信令的分量载波 CC1确认 为信令所指示的无线资源所在的分量载波, 同时, 用户终端 1处理该 信令以获得信令中的无线资源域 RB— DATA , 根据上述分量载波 CC 1 和信令中的无线资源域 RB_DATA,可定位信令所指示的无线资源为: 无线资源 RB12。
然后, 在步骤 S203中, 用户终端 1在 TSPS— retran时刻, 在分量载 波 CC1的无线资源 RB12上执行标识 SPS C-RNTI1所对应的半静态 调度传输 SPS1的重传输。
本技术领域中, 可以理解为: 在不同的应用场景中, 来自基站 2 的信令所基于标准的小区无线网络临时标识 Normal C-RNTI, 所对应 的传输也可以不同, 例如, 在上述实施例中, 用户终端上的标识 SPS
C-RNTI 1 所对应的半静态调度传输 SPS1, 处于等待重传状态, 而在 此过程中无法启动新的动态传输。 则此时, 标准的小区无线网络临时 标识 Normal C-RNTI 所对应的传输也可以理解为是半靜态调度传输 SPS1。
根据本发明的另一实施例, 用户终端 1所配置的半静态调度传输 SPS1 和 SPS2 共享一个公共的半静态调度小区无线网络临时标识 Common SPS C-RNTI, 且半静态调度传输 SPS1和 SPS2分别被—— 对应地配置于分量载波 CC1和 CC2上。
在步骤 S201 中, 根据公共的半静态调度小区无线网络临时标识 Common SPS C-RNTI, 用户终端 1在分量载波 CC4上接收到来自基 站 2的物理下行控制信道(PDCCH )信令 6, 该信令中包含载波指示 域 CIF, 该信息指示的分量载波为 CC1。
在步骤 S202中, 用户终端 1处理步骤 S201 中接收到的信令, 用 户终端 1根据 CIF的指示信息, 将承载该信令的分量载波 CC1确认 为信令所指示的无线资源所在的分量载波, 同时, 用户终端 1处理该 信令以获得信令中的无线资源域 RB— DATA, 根据上述分量载波 CC1 和信令中的无线资源域 RB一 D ATA,可定位信令所指示的无线资源为: 无线资源 RB12。
然后, 在步骤 S203中, 用户终端 1判断: 分量载波 CC1上配置 有一个半静态调度传输 SPS1 , 且正在处于等待重传状态。 接着, 用 户终端 1在 TSPS _retran时刻,在分量载波 CC1的无线资源 RB12上执行 半静态调度传输 SPS1的重传输。
此处, 本领域技术人员应该理解: 步骤 203 中对无线资源 RB12 的具体定位, 和步骤 S203中, 分量载波 CC1上是否配置有一个半静 态调度传输以及是否处于等待重传输的状态, 这两个技术特征之间无 时序的限制。
可选地, 在上述步骤 S201 中接收到的物理下行控制信道信令 PDCCH 还可以包括用以指示是否进行所述重传输的信息, 或者用以 指示是否进行一次新传输的信息,例如图 6中所示的新数据指示 N D I ,
相应地, 在步骤 S203中, 还可以包括对信令中的新数据指示 NDI的 判断: 如果新数据指示 NDI内容为指示用户终端 1进行重传, 则用户 终端 1在分量载波 CC1的无线资源 RB12上执行标识 SPS C-RNTI1 所对应的半静态调度传输 SPS1的重传输。 如果新数据指示 NDI内容 为指示用户终端 1 进行新数据传输, 则用户终端 1 在分量载波 CC1 的无线资源 RB12上启动一次新的动态传输, 例如: 在分量载波 CC1 上执行的动态传输 DS1, 而取消半静态调度传输 SPS1的重传输。
另外, 根据本发明的另一实施例, 如图 5所示, 如果移动终端 1 在分量载波 CC1上配置的半静态调度传输 SPS1 , 在½ 51^时刻被配置 发生一次半静态调度传输, 但此前, 在 t2 DS时刻发生的一次在分量载 波 CC1上执行的动态传输 DS1未成功,基站 2在 tNACK时刻向用户终 端 1发送接收失败消息, 根据 HARQ同步上行传输机制, 用户终端 1 在 tDS ^an时刻需要做在分量载波 CC1上的动态传输 DS1的上行重传 输, 而此时间点恰好和半静态调度传输 SPS1被配置的时间点在时域 上重合, 则在这种场景下, 根据本发明的另一实施例, 首先, 执行步 骤 S201 , 在分量载波 CC1上接收到来自基站 2的物理下行控制信道 ( PDCCH ) 信令 6 , 且该信令基于标准的小区无线网络临时标识 Normal C-RNTI。
其次, 在步骤 S202中, 用户终端 1处理步骤 S201 中接收到的信 令, 该信令由分量载波 CC1 承载发送, 因此, 用户终端 1将分量载 波 CC1 确认为信令所指示的无线资源所在的分量载波, 同时, 用户 终端 1处理该信令以获得信令中的无线资源域 RB— DATA, 根据上述 分量载波 CC1和信令中的无线资源域 RB— DATA, 可定位信令所指示 的无线资源为: 无线资源 RB12。
然后, 在步骤 S203中, 用户终端 1判断: 分量载波 CC1上配置 有一个半静态调度传输 SPS1。 根据标准的小区无线网络临时标识 Normal C-RNTI, 用户终端 1在 T2 SPS时刻, 在分量载波 CC1的无线 资源 RB 12上执行标识 Normal C-RNTI所对应的在分量载波 CC1上执 行的动态传输 DS1 的重传输, 而取消在此时刻的半静态调度传输
SPS1的传输。
可选地, 与之前的实施例相似, 上述方法也可以在步骤 S201 中 接收到包含载波指示域 CIF的信令, 然后在 S201 步骤中确定相应的 分量载波以及在 S203中以标识 Normal C-RNTI所对应的动态传输, 例如在分量载波 CC1上执行的动态传输 DS1的重传输, 取代在配置 时间点 T2 SPS的半静态调度传输 SPS1的传输。本领域技术人员对此完 全可以理解, 所以, 此处不再赘述。
反之,本领域技术人员也完全可以理解:对于上述实施例的情况, 可以在步骤 S201 中, 接收到基于标识 SPS C-RNTI1或 Common SPS C-RNTI的信令,在步骤 S202中,以承载信令的载波的默认协议方式, 或者载波指示域 CIF的信息确定指示的无线资源所在的分量载波。然 后,在步驟 S203中,在 T2 SPS时刻,在对应的分量载波的无线资源上, 以半静态调度传输 SPS1取代在分量载波 CC1上执行的动态传输 DS1 的重传输, 此处不再赘述。
上述的各类所谓的 "重传输", 在有些应用场景下, 也属于本发 明的 "传输" 范畴之内。 上述的在分量载波 CC1 上执行的动态传输 DS1的重传输对半静态调度传输 SPS1的配置时间点的传输的取代, 或者半静态调度传输 SPS1的配置时间点的传输对在分量载波 CC1上 执行的动态传输 D S 1的重传输的取代,都属于本发明的技术方案范畴 之内。
基站 2在与用户终端 1进行无线通信时, 会因为环境干扰、 通信 实时质量等无线资源的情况确定调度策略, 从而对通信的无线资源进 行动态调度和动态配置。
根据本发明一实施例, 用户终端 1 的分量载波 CC1 上配置有半 静态调度传输 SPS1 , 在资源 RB11上执行, 如图 4所示, 其半静态调 度传输的一个配置时间点是 TQ SPS如图 5所示。
根据本发明的一实施例, 基站 2根据调度策略, 确定: 在配置时 间点 T。SPS上, 需要在分量载波 CC1的实时通信盾量较好的无线资源 RB12上执行半静态调度传输 SPS1 , 而在该时刻取消实时通信质量较
差的无线资源 RB11上的半静态调度传输 SPS1 的执行, 则本实施例 提供了一种在无线网络的基站 2中用于用户终端 1中的上行传输调度 方法, 包括步骤 S301 : 基站 2发送基于半静态调度小区无线网络临 时标识的物理下行控制信道信令, 且该半静态调度小区无线网络临时 标识对应一半静态调度传输; 该信令中指示的执行所述半静态调度传 输的无线资源所在的分量载波, 与所述半静态调度传输所配置的分量 载波可以不同或者相同。具体地,在时间点 T。SPS时刻之前,比如 4ms, 发送基于半静态调度小区无线网络临时标识 SPS C-RNTI1 的物理下 行控制信道信令, 选择分量载波 CC1 承载发送该信令, 这代表信令 指示的无线资源位于分量载波 C C 1上,结合无线资源域 RB—D ATA共 同指示了:基站指定的无线资源为分量载波 CC1上的无线资源 RB12。
此实施例中, 所谓基于半静态调度小区无线网络临时标识 SPS C-RNTI1的物理下行控制信道信令,这里是指的半静态调度小区无线 网络临时标识 SPS C-RNTI1的信息已被都隐含在 PDCCH信令的 CRC 校验位里。 相对地, 用户终端 1接收 PDCCH信令时, 就结合其所配 置的半静态调度传输的半静态调度小区无线网络临时标识 SPS C-RNTI1和循环冗余校 -险码进行解掩码, 即可判断该 PDCCH信令是 否是发给本终端的。 本实施例中的基站 2基于小区无线网络临时标识 进行发送 PDCCH信令的原理, 以及用户终端 1基于小区无线网络临 时标识进行接收的原理, 也可以应用于本发明的其他实施例中, 以下 不再赘述。
可选地, 基站选择分量载波 CC4 承载发送物理下行控制信道信 令, 而信令的载波指示域 CIF指示: 信令所指示的无线资源位于分量 载波 CC1上, 结合无线资源域 RB_DATA共同指示了: 基站指定的无 线资源为分量载波 CC1上的无线资源 RB12。

根据本发明的一实施例, 用户终端 1 所配置的半静态调度传输
SPS1 和 SPS2 共享一个公共的半静态调度小区无线网络临时标识 Common SPS C-RNTI, 且半静态调度传输 SPS1和 SPS2分别被—— 对应地配置于分量载波 CC1和 CC2上。 则基站 2执行步骤 S301 : 发 送基于半静态调度小区无线网络临时标识 Common SPS C-RNTI的物 理下行控制信道信令, 基站选择分量载波 CC4 承载发送物理下行控 制信道信令, 而信令的载波指示域 CIF指示: 信令所指示的无线资源 位于分量载波 CC1上, 结合无线资源域 RB_DATA共同指示了: 基站 指定的无线资源为分量载波 CC1上的无线资源 RB12。
如图 4所示,用户终端 1在分量载波 CC1的无线资源 RB11上被 配置有一个半静态调度传输 SPS1 , 以及在分量载波 CC1的其他无线 资源上有一个在分量载波 CC1 上执行的动态传输 DS1 , 对应标准的 小区无线网络临时标识 Normal C-RNTL
根据本发明的一实施例, 基站 2根据调度策略, 在 TQ sps时刻, 需要在分量载波 CC1 的无线资源 RB12上执行标识 Normal C-RNTI 所对应的在分量载波 CC1 上执行的动态传输 DS1 , 而取消在此时刻 的半静态调度传输 SPS1的传输,基站在 T。SPS时刻前一段时间, 比如 4ms, 执行步骤 S301 : 发送基于标准的小区无线网络临时标识的物理 下行控制信道信令, 且该信令中指示的无线资源所在的分量载波上配 置有一半静态调度传输。 具体地, 基站 2发送基于标准的小区无线网 络临时标识 Normal C-RNTI的物理下行控制信道信令,选择分量载波 CC1承载发送该信令,这代表信令指示的无线资源位于分量载波 CC1 上, 结合无线资源域 RB— DATA共同指示了: 基站指定的无线资源为 分量载波 CC1上的无线资源 RB12。
可选地, 基站选择分量载波 CC4 承载发送物理下行控制信道信 令, 而信令的载波指示域 CIF指示: 信令所指示的无线资源位于分量 载波 CC1上, 结合无线资源域 RB— DATA共同指示了: 基站指定的无 线资源为分量载波 CC1上的无线资源 RB11。
根据本发明的一实施例, 如果用户终端 1所配置的半静态调度传
输 SPS1 和 SPS2共享一个公共的半静态调度小区无线网络临时标识 Common SPS C-RNTI, 且半静态调度传输 SPS1和 SPS2分别被—— 对应地配置于分量载波 CC1和 CC2上。 则基站 2执行步骤 S301 : 发 送基于半静态调度小区无线网络临时标识 Common SPS C-RNTI的物 理下行控制信道信令, 基站选择分量载波 CC4 承载发送物理下行控 制信道信令 6, 而信令的载波指示域 CIF指示: 信令所指示的无线资 源位于分量载波 CC1上, 结合无线资源域 RB_DATA共同指示了: 基 站指定的无线资源为分量载波 CC1上的无线资源 RB12。
如图 4所示,用户终端 1在分量载波 CC1的无线资源 B 11上被 配置有一个半静态调度传输 SPS1 ,在基站 2接收 T。 SPS时刻的传输时, 发生错误, 基站 2在 TNACK时刻发送接收失败消息(未在图中示出), 而在 TSPS _^an时刻, 用户终端 1需要做一次重传输, 根据本发明一实 施例, 在 TSPS_^an时刻之前, 半静态调度传输 SPS1处于等待重传的 状态。根据本发明的一实施例,基站 2根据调度策略,确定:在 TSPS _retnin 时刻,需要在分量载波 CCl的无线资源 RB12上执行半静态调度传输 SPS1的重传输。 基站 2在 TSPS retran时刻前一段时间, 比如 4ms, 执行 步骤 S301 :发送基于半静态调度小区无线网络临时标识 SPS C-RNTI1 的物理下行控制信道信令, 基站 2选择分量载波 CC4承载发送物理 下行控制信道信令, 而信令的载波指示域 CIF指示: 信令所指示的无 线资源位于分量载波 C C 1上,结合无线资源域 RB— D ATA共同指示了: 基站 2指定的无线资源为分量载波 CC1上的无线资源 RB12。
根据本发明的另一实施例, 如果用户终端 1所配置的半静态调度 传输 SPS1 和 SPS2共享一个公共的半静态调度小区无线网络临时标 识 Common SPS C-RNTI, 且半静态调度传输 SPS1和 SPS2分别被一 一对应地配置于分量载波 CC1和 CC2上。 则基站 2执行步骤 S301 : 发送基于半静态调度小区无线网络临时标识 Common SPS C-RNTI的 物理下行控制信道信令, 基站选择分量载波 CC4 承载发送物理下行 控制信道信令, 而信令的载波指示域 CIF指示: 信令所指示的无线资 源位于分量载波 CC1上, 结合无线资源域 RB一 DATA共同指示了: 基
站指定的无线资源为分量载波 CC1上的无线资源 RB 12。
根据本发明的另一实施例, 用户终端 1依然在: TNACK 时刻接收 到基站 2的接收失败消息, 或者未有回应消息, 则用户终端 1继续执 行失败的重传。 基站 2根据调度策略, 确定: 在 TSPS— retran时刻, 需要 在分量载波 CC1的无线资源 RB12上执行半静态调度传输 SPS1的重 传输。
此时, 除了上面实施例中可以发基于 SPS C-RNTI1的信令之外, 作为一种备选的方案, 基站 2也可以在 TSPS retran时刻前一段时间, 比 如 4ms, 执行步骤 S301 : 发送基于标准的小区无线网络临时标识物理 下行控制信道信令, 且该信令中指示的无线资源所在的分量载波上配 置有一处于半静态调度传输的重传输时间点的半静态调度传输。 具体 地, 基站 2 发送基于令基于标准的小区无线网络临时标识: Normal C-RNTI的物理下行控制信道信令, 选择分量载波 CC1承载发送该信 令, 这代表信令指示的无线资源位于分量载波 CC1 上, 结合无线资 源域 RB— DATA 共同指示了: 基站指定的无线资源为分量载波 CC1 上的无线资源 RB12。
可选地,上述基站 2发送的基于 Normal C-RNTI的物理下行控制 信道信令中还包括: 指示是否执行所述重传输的信息, 或者启动一次 新传输的信息, 例如, 新数据指示 NDI, 该信息可指示用户终端 1执 行相关传输, 比如 SPS1的重传输, 或者指示用户终端 1启动一次新 的动态传输。
如果用户终端 1所配置的半静态调度传输 SPS1和 SPS2共享一 个公共的半静态调度小区无线网络临时标识 Common SPS C-RNTI, 且半静态调度传输 SPS1 和 SPS2分别被——对应地配置于分量载波 CC 1和 CC2上。则根据本发明的另一实施例,则基站 2执行步骤 S301: 发送基于半静态调度小区无线网络临时标识 Common SPS C-RNTI的 物理下行控制信道信令, 基站选择分量载波 CC4 承载发送物理下行 控制信道信令, 而信令的载波指示域 CIF指示: 信令所指示的无线资 源位于分量载波 CC1上, 结合无线资源域 RB DATA共同指示了: 基
站指定的无线资源为分量载波 CCl上的无线资源 RB12。
可选地, 上述基站 2发送的基于标识 Common SPS C-RNTI的物 理下行控制信道信令中还包括: 新数据指示 NDI, 该信息可指示用户 终端 1执行相关传输, 比如 SPS1的重传输, 或者指示用户终端 1启 动一次新的动态传输。
如图 5所示, 如果移动终端 1在分量载波 CC1上配置的半静态 调度传输 SPS1 , 在 t2 SPS时刻被配置发生一次半静态调度传输, 但此 前, 用户终端 1在 t2 DS时刻执行的一次在分量载波 CC1上执行的动 态传输 DS1未成功, 基站 2在 tNACK时刻向用户终端 1发送接收失败 消息, 根据 HARQ同步上行传输机制, 用户终端 1在: tDS」etran时刻 需要做在分量载波 CC1上执行的动态传输 DS1的上行重传输, 而此 时间点恰好和半静态调度传输 SPS1被配置的时间点在时域上重合。 基站 2根据调度策略, 确定: 在 T2 sps时刻, 需要调度用户终端 1执 行在分量载波 CC1上执行的动态传输 DS1 的重传输, 而取消在此时 刻的半静态调度传输 SPS1的传输。 则基站 2执行步骤 S301 : 发送基 于令基于标准的小区无线网络临时标识 Normal C-RNTI 的物理下行 控制信道信令, 选择分量载波 CC1 承载发送该信令, 这代表信令指 示的无线资源位于分量载波 CC1上,结合无线资源域 RB— DATA共同 指示了: 基站指定的无线资源为分量载波 CC1上的无线资源 RB12。
可选地, 与之前的实施例相似, 上述基站 2发送的基于 Normal C-RNTI的物理下行控制信道信令以其载波指示域 CIF指示: 信令所 指示的无线资源位于分量载波 CC1上, 此时基站 2可选择 CC2, CC3 或者 CC4 承载该信令, 本领域技术人员对此完全可以理解, 所以, 此处不再赘述。 当然也可以使用 CC1 承载该信令, 此时, 根据本发 明的实施例, 可以以载波指示域 CIF 所显式地指示出的分量载波为 准。
反之, 在上述情况中, 如果基站 2根据调度策略, 确定: 在 T2 SPS 时刻,需要调度用户终端 1执行配置在此时刻的半静态调度传输 SPS1 的传输, 而取消在分量载波 CC1上执行的动态传输 DS1的重传输。
则基站 2执行步骤 S301 :发送基于标识 SPS C-RNTI1或 Common SPS C-RNTI 的物理下行控制信道信令, 同时, 以承载信令的载波的默认 协议方式, 或者载波指示域 CIF指示出无线资源所在的分量载波, 结 合无线资源域 RB D ATA共同指示了: 相应的分量载波上的基站所要 指定的无线资源。
需要说明的是: 此处的实施例, 仅仅以两种传输在同一时刻占用 相同的无线资源的情况为例进行说明。 如果基站在信令中的为某传输 (例如在分量载波 CC1上执行的动态传输 DS1 )指定的无线资源(例 如 RB41 ) 并未被另一传输使用, 则原传输 (例如半静态调度传输 SPS1 ), 仍在原资源(例如 RB11 )上在被配置的时间点上被用户终端 1执行; 而同一时刻, 用户终端 1也完全可以在另外一个载波的另外 的无线资源 (例如 RB41 )上执行该传输(例如在分量载波 CC1上执 行的动态传输 DS1 ), 此种正常的信令调度, 按照正常的调度方法进 行处理。
上述的各类所谓的 "重传输", 也属于本发明的 "传输" 范畴之 内, 上述的在分量载波 CC1上执行的动态传输 DS1 的重传输对半静 态调度传输 SPS1 的配置时间点的传输的取代, 或者半静态调度传输 SPS1的配置时间点的传输对在分量载波 CC1上执行的动态传输 DS1 的重传输的取代, 都属于本发明的技术方案范畴之内。 另外, 对上述 的动态传输 (例如, 在分量载波 CC1 上执行的动态传输 DS1 ) 的重 传输的调度,一般地,发生在该传输的首次传输所发生的分量载波上, 对半静态调度传输(例如, SPS1 ) 的重传输, 亦如此。

信令接收模块 701 , 用于接收物理下行控制信道信令。 可选地, 在用户终端 1 的半静态调度传输的配置时间点之前, 信令接收模块 701可用监测其监视集 (monitoring set ) 的分量载波上的物理下行控 制信道信令。
资源定位模块 702连接于信令接收模块 701 , 获取来自信令接收 模块 701的信令信息, 该资源定位模块 702用于确定信令所指示的无 线资源所在的分量载波, 进而结合信令中信息, 确定信令所指定的无 线资源的位置。
传输模块 703连接于资源定位模块 702,获取经资源定位模块 702 分析处理的资源定位信息。 传输模块 703作为该装置的输出模块, 用 于根据信令中所基于的小区无线网络临时标识, 在相应的分量载波的 指示的无线资源上执行与小区无线网络临时标识相应的上行传输。
在一些实施例的应用场景的描述中, 传输模块 703所执行的上行 传输也包括传输失败后的重传输。 上述的信令接收模块负责监视的监 视集( monitoring set ) 为该终端所被配置以用于接收物理下行控制信 道信令的分量载波的集合 /组。
该装置在同一个分量载波上执行动态传输或半静态调度传输及 其可能发生的重传输。
