在专用信道(DCH，Dedicated Channel)业务过程中，网络侧通过专用物理信道(DPCH，Dedicated Physical Channel)承载下行控制信息和业务数据；用户终端(简称为终端)侧通过专用物理控制信道(DPCCH，Dedicated Physical Control Channel)承载上行控制信息，通过专用物理数据信道(DPDCH，Dedicated Physical Data Channel)承载上行业务数据。
高速上行分组接入(HSUPA，High Speed Uplink Packet Access)技术中引入新的下行信道，包括：增强绝对授权信道(E-AGCH，Enhanced Absolute Grant Channel)、增强相对授权信道(E-RGCH，Enhanced Relative Grant Channel)、以及增强专用信道混合自动重传请求(HARQ)指示符信道(E-HICH，Enhanced DCH Hybrid ARQ Indicator Channel)；其中，网络侧通过E-AGCH和E-RGCH动态通知终端侧的增强专用信道(E-DCH)信道所占用的物理资源信息，终端侧根据E-AGCH和E-RGCH承载的控制信息进行用于承载上行控制信息的上行增强专用物理控制信道(E-DPCCH，Enhanced Dedicated Physical Control Channel)的发送、以及用于承载上行业务数据的增强专用物理数据信道(E-DPDCH，Enhanced Dedicated Physical Data Channel)的发送，并接收增强专用信道混合自动重传请求(HARQ)指示符信道(E-HICH，Enhanced DCH Hybrid ARQ Indicator Channel)的接 收，E-HICH用于承载网侧是否成功接收上行E-DPDCH信道的ACK/NACK反馈信息。
HSUPA相关技术中，E-DPCCH和E-DPDCH的发送时刻的计算取决E-DCH的传输时间间隔(TTI，Transmission Time Interval)，即在每个TTI内计算发送E-DPCCH和E-DPDCH的发送时间点，计算频次和复杂度高，消耗过多的计算资源。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明实施例中，对于HUSUPA业务场景，在接收到HSUPA下行信道(如E-AGCH、E-RGCH和E-HICH中的至少一个信道)的传输数据后，根据上行信道接收完成时的连接帧的TTI计数，确定下行信道所对应的上行信道(E-DPDCH和E-DPCCH)的发送时刻，并在所计算出的发送时刻发送上行信道。
本发明实施例记载一种上行信道发送控制方法，图1是本发明实施例中上行传输控制方法的实现流程示意图；如图1所示，本发明实施例记载的上行传输控制方法包括如下步骤：
步骤101：在第一触发点对连接帧的TTI进行计数。
步骤102：根据下行信道的帧尾是否超前所述连接帧帧头预设距离，生成判决结果。
步骤103：在所述第一触发点和第二触发点查询到所述下行信道接收完成时，根据对连接帧TTI进行计数得到的计数值，或根据所述计数值以及所述判决结果，确定发送与所述下行信道对应的上行信道时的TTI计数值。
作为一个实施方式，所述第一触发点为E-DCH帧头(也即连接帧的第1024码片)；当TTI为2ms时，所述第二触发点为在连接帧的第4864码片、连接帧的第12544码片、连接帧的第20224码片、连接帧的第27904码片、以及连接帧的第35584码片；当TTI为10ms时，所述第二触发点为连接帧的第27904码片。

下面结合上行信道发送的具体应用场景进行说明，本发明实施例还记载一种上行信道发送的处理流程，图3是本发明实施例中上行信道发送控制方法的处理流程图；本实施例基于图2a至图2c所示的上行信道发送控制装置，如图3所示，包括以下步骤：
步骤301：HSUPA业务被激活时，使能TTI计数器模块。
步骤302：下行信道映射初始值计算模块计算下行信道映射初始值。
作为一个示例，下行信道映射初始值可以根据公式(1)确定：
NoDlChanInit＝{[(τDownlink,n–τDPCH×2560+38400)mod LE-DCH TTI]+d×2560+LDlFrame–1024]}/LE-DCH TTI   (1)
其中，NoDlChanInit表示下行信道映射初始值，LE-DCH TTI表示E-DCH TTI长度，d表示下行信道帧尾超前所对应的上行信道(包括E-DPDCH和E-DPCCH)帧头的距离，LDlFrame表示下行信道帧长度，τDPCH是DPCH相对于P-CCPCH帧偏移与2560的比值，单位为码片(码片)，也τDPCH代表τDPCH×2560个码片；由于上行信道与连接帧的TTI是对应的，因此，下行信道帧尾超前所对应的上行信道帧头的距离，等于下行信道帧尾超前连接帧帧头的距离。
由于E-DPDCH和E-DPCCH是同步发送的，因此，下行信道帧尾超前所对应的上行信道E-DPDCH帧头的距离，与下行信道帧尾超前所对应的上行信道E-DPCCH帧头的距离一致。
τDownlink,n的取值与下行信道的类型有关，在HSUPA业务场景中下行信道包括：E-HICH、E-RGCH和E-AGCH；相应地，τDownlink,n采用公式(2)至(4)表示：
τDownlink,n＝τE-HICH,n，下行信道为E-HICH   (2)
τDownlink,n＝τE-RGCH,n，下行信道为E-RGCH   (3)
τDownlink,n＝τE-AGCH,n，下行信道为E-AGCH   (4)
下面对τDownlink,n对应不同下行信道的取值进行说明：
1)下行信道为E-HICH时，确定τE-HICH,n
当E-DCH TTI采用10ms时，E-HICH帧长度为8ms，E-HICH相对于P-CCPCH的帧偏移E-HICH是τE-HICH,n，τE-HICH,n的单位采用码片，其中，
Figure PCTCN2014090975-appb-000001
τDPCH,n表示DPCH相对于P-CCPCH的帧偏移，τDPCH,n＝Tn×256(码片)，Tn∈{0，1，…，149}。
当E-DCH TTI是2ms时，E-HICH帧长度为＝2ms，E-HICH相对于P-CCPCH的帧偏移是τE-HICH,n，其中，

τDPCH,n表示DPCH相对于P-CCPCH帧偏移，τDPCH,n＝Tn×256(码片)，Tn∈{0，1，…，149}。
2)下行信道为E-RGCH时，确定τE-RGCH,n
a)当给终端发送E-RGCH的小区属于E-DCH服务链路集时，
当E-DCH TTI采用10ms时，E-RGCH帧长度为8ms，E-RGCH相对于P-CCPCH的帧偏移是τE-RGCH,n，其中，

b)当给终端发送E-RGCH的小区不属于E-DCH服务链路集时，E-RGCH帧长度是10ms，E-RGCH相对于P-CCPCH的帧偏移是5120(码片)。
3)下行信道为E-AGCH时，确定τE-AGCH,n
E-AGCH帧长度与E-DCH TTI长度一致，E-AGCH相对于P-CCPCH的帧偏移τE-AGCH,n是5120(码片)。
下面对确定下行信道帧尾到(也即超前)所对应的上行信道(包括E-DPCCH和E-DPDCH)帧头的距离d进行说明，需要指出的是，由于连接帧(Connection Frame)TTI与上行信道的TTI时对应的，因此，下行信道帧尾到(也即超前)所对应的上行信道(包括E-DPCCH和E-DPDCH)帧头的距离时间，等同于下行信道帧尾到(也即超前)连接帧的帧头的距离。
作为一个示例，下行信道帧尾到所对应的E-DPDCH帧头的距离可以通过表1和表2确定：

Figure PCTCN2014090975-appb-000006
表1
Figure PCTCN2014090975-appb-000007
表2
表1所示为10ms E-DCH TTI场景中不同下行信道帧尾到所对应的E-DPDCH帧头的距离，表2所示为2ms E-DCH TTI场景中下行信道帧尾到所对应的E-DPDCH帧头的距离，表1和表2中的dE-RGCH、dE-HICH、dE-AGCH对应表示E-RGCH、E-HICH、E-AGCH的帧尾到E-DPDCH帧头的距离与2560的比值(单位为码片)，表1和表2中示出了不同τDPCH取值范围内dE-RGCH、dE-HICH、dE-AGCH，这样可以根据实际应用场景中τDPCH的取值以及TTI的长度(2ms或10ms)，结合表1和表2快速确定下行信道帧尾到所对应的E-DPDCH帧头的距离，需要指出的是，由于E-DPDCH和E-DPDCH总是同步发送，因此，下行信道帧尾到所对应的E-DPCCH帧头的距离，与下行信道帧尾到所对应的E-DPDCH帧头的距离一致。
在10ms E-DCH TTI场景中，E-DCH TTI长度也即LE-DCH TTI为38400(码片)，在2ms E-DCH TTI场景中，E-DCH TTI长度也即LE-DCH TTI为7680(码 片)。
下面以10ms E-DCH TTI场景为例，，对确定NoDlChanInit的处理过程进行说明。
a)10ms E-DCH TTI场景中，以τDPCH,n为5120(码片)为例，根据公式5(2)，公式(1)中的τDownlink,n取值为τE-HICH,n，HSUPA下行信道E-HICH相对于P-CCPCH帧偏移τE-HICH,n可以根据公式(6)确定，即：
Figure PCTCN2014090975-appb-000008
(码片)
b)τDPCH＝τDPCH,n/2560＝2(ms)；
c)E-DCH TTI＝10ms时，根据相关技术的协议规定，E-DCH TTI长度也即LE-DCH TTI为38400码片；
d)下行信道E-HICH帧尾到所对应的E-DPDCH帧头的距离可以根据表1确定，参见表1，当LE-DCH TTI＝10ms，τDPCH＝2时，根据表1中第2行第4列，可以确定E-HICH帧尾到所对应的E-DPDCH帧头的距离，即dE-HICH＝8.4+(τDPCH–1)＝8.4+(2–1)＝9.4(单位为码片)，也即dE-HICH代表dE-HICH×2560个码片；
e)参见公式(6)的说明，当E-DCH TTI为10ms时，下行E-HICH帧长度即8ms，也即LDlFrame为30720(码片)。
将上述τE-HICH,n、τDPCH、LE-DCH TTI、LDlFrame、dE-HICH代入公式(1)，得到
NoDlChanInit＝﹛[(-10240－2×2560+38400)mod 38400]+9.4×2560+30720–1024﹜/38400＝2(码片)
需要说明的是，以下步骤303和步骤304为并行执行的步骤。
步骤303：下行信道帧尾判决器进行判决输出。
判断下行信道帧尾超前所对应的上行信道帧头的距离是否小于预设距 离；如果小于，则输出1；否则输出0。
判断下行信道帧尾超前所对应的上行信道帧头的距离是否小于预设距离，可以通过以下方式实现：将(下行信道帧尾到所对应的E-DPDCH帧头的距离–1024)对E-DCH TTI长度进行取模预算，所得值如果小于一个时隙也即2560码片，则下行信道帧尾判决器输出1，否则，下行信道帧尾判决器输出0；其中，下行信道帧尾到所对应的上行信道帧头的距离d在步骤302中已经进行了说明，这里不再赘述。
步骤304：触发器子模块1和触发器子模块2进行初始化设置。
触发器子模块1将E-DCH帧头时间点(即连接帧第1024码片)作为触发器子模块1的触发条件；
当E-DCH TTI为10ms时，触发器子模块2将E-DCH帧内的特定时间点即连接帧第27904码片做为触发器子模块2的触发条件；当E-DCH TTI为2ms时，触发器子模块2将E-DCH帧内的以下时间点作为触发器子模块2的触发条件：连接帧第4864码片、连接帧第12544码片、连接帧第20224码片、连接帧第27904码片和连接帧第35584码片。
需要指出的是，当触发器子模块1和触发器子模块2每一次被触发时，都会触发TTI计数器的计数加1；当EDCH TTI为10ms时，TTI计数器的值达到连接帧周期即256时，TTI计数器将计数进行清0；当EDCH TTI为2ms时，TTI计数器的值达到连接帧周期1280时，TTI计数器将计数进行清0。
步骤305：触发器子模块1的触发条件是否满足，如果满足，则触发检测模块执行步骤306；否则，执行步骤308。
步骤306：查询模块查询是否已经收到网络侧的下行信道(E-AGCH、E-RGCH和E-HICH中的一个以上)，当已经收到网络侧的下行信道时，则执行步骤307；当没有收到网络侧的下行信道时，执行步骤308。
步骤307：查询模块查询TTI计数器模块当前的值NoCurTti，确定下行信道(即接收模块所接收的下行信道)控制的上行信道(包括E-DPDCH和E-DPCCH)的TTI计数值NoTti，并转入步骤311。
NoTti用于控制发送上行信道时的TTI计数；当E-DCH TTI为10ms时，下行信道控制的E-DPDCH TTI计数值NoTti可以根据公式(9)确定：
NoTti＝(NoCurTti+NoDlChanInit)mod 256   (9)
当E-DCH TTI为2ms时，上行信道(包括E-DPDCH和E-DPCCH)控制的下行信道的TTI计数值NoCurTti可以根据公式(10)确定：
NoTti＝(NoCurTti+NoDlChanInit)mod 1280   (10)
其中，NoTti为发送上行信道时的TTI计数；NoDlChanInit的确定已经在步骤302中进行了说明，这里不再赘述。
步骤308：触发器子模块2的触发条件是否满足，如果满足，则触发检测模块执行步骤309，否则，返回步骤305。
步骤309：查询模块查询是否接收下行信道完毕，下行信道包括网络侧的E-AGCH、E-RGCH和E-HICH中的一个以上，当接收下行信道完毕时，则执行步骤310；当没有接收下行信道完毕时，返回步骤305。
步骤310：查询模块查询TTI计数器的值当前计数NoCurTti，确定下行信道对应的上行信道(包括E-DPDCH和E-DPCCH)的TTI计数值NoTti。
NoTti为发送上行信道时的TTI计数；以确定E-DPDCH的TTI计数值NoTti为例，当E-DCH TTI为10ms时，所接收到的下行信道对应的下行信道的TTI计数值NoCurTti可以根据公式(11)确定：
NoTti＝(NoCurTti+NoDlChanInit–下行信道帧尾判决器的输出值)mod 256(11)
当E-DCH TTI为2ms时，以确定E-DPDCH的TTI计数值NoTti为例，下行信道控制的E-DPDCH TTI计数值NoCurTti根据可以公式(12)确定：
NoTti＝(NoCurTti+NoDlChanInit–下行信道帧尾判决器的输出值)mod 1280(12)
步骤311：在TTI计数器值达到NoTti前，按照下行控制信道承载的控制值进行发送E-DPCCH和E-DPDCH的数据准备，在TTI计数器值NoCurTti增加到NoTti时，发送上行信道(包括E-DPCCH和E-DPDCH)。
步骤307中确定NoTti时所使用的NoCurTti为在触发器子模块1产生触发信号且接收到网络侧的下行信道的时刻TTI计数器模块的计数值，TTI计数器模块的值NoCurTti后续会由于触发器模块1和触发器模块2的触发继续增长，当增长后的计数值NoCurTti与确定的NoTti一致时，发送上行信道。
