Description

载波聚合方法及设备 技术领域
本发明涉及通信技术领域，尤其涉及一种载波聚合方法及设备。
背景技术
随着智能终端用户数量的增长、用户业务量和数据吞吐量的增加，对通信速率提出了更高要求。并且，由于无线频谱资源短缺，很难找到连续的大带宽用于移动通信。基于此，在高级长期演进(Long Term Evolution-Advanced，LTE-A)中引入了载波聚合技术，即将多个连续或不连续的频谱聚合使用，解决移动通信对大带宽的需求，同时提高无线频带中零散频谱资源的利用率。
如图1所示的载波聚合场景中，终端通过两个成员载波CC1和CC2与基站同时通信，事实上，LTE-A可以支持不多于5个成员载波的聚合。
目前智能终端出现了一些要求低时延的应用，比如交互式游戏、智能交通等等，这对无线通信的时延提出了较高要求。因此，如何降低时延，成为通信中的关键问题。
目前主要通过降低传输时间间隔(Transmission Time Interval，TTI)的方式来降低时延。
本文中帧配置是指一个无线帧中包含的上行子帧、下行子帧以及特殊子帧的数目以及上行、下行和特殊子帧之间的关系，其中特殊子帧必须包含保护时间，还可能包括上行部分和/或下行部分。
LTE的每个TTI为1毫秒(ms)，不同帧配置对应的时延值不同，假设上行链路基站侧的处理时延为1.5ms，用户侧的处理时延为1ms，下行链路基站侧的处理时延为1ms，用户侧的处理时延为1.5ms。不同帧配置下的帧对齐时延值不同，帧对齐时间是指从业务到达至业务能够获得空口子帧传输机会之间的等待时间。下面以帧配置0为例，帧配置0对应的帧结构如图2所示，下行数据传输中，TTI为1ms时，LTE的帧配置0的下行链路的时延为：基 站侧的处理时延1ms+帧对齐时延1.7ms+用户侧的处理时延1.5ms+一个TTI的时长1ms＝5.2ms。
按照同样的方式，可分别确定TTI为1ms时帧配置0～6下上行或下行数据传输的时延，如表1所示：
表1
LTE的帧配置 0 1 2 3 4 5 6
上行时延(ms) 4.6 5.2 6 6.8 7.6 8.5 4.9
下行时延(ms) 5.2 4.6 4.2 4.6 4.3 4.1 4.9
通过降低TTI的方式降低时延，采用与LTE兼容的TTI为0.5ms的帧配置，即LTE的1ms下行子帧分为2个0.5ms的下行子帧，LTE的1ms特殊子帧分为1个0.5ms的下行子帧和1个0.5ms的特殊子帧，LTE的1ms的上行子帧分为2个0.5ms的上行子帧，如图3所示为TTI为0.5ms的帧配置的结构示意图。
假设基站侧的处理时延为0.2ms,用户侧的处理时延为0.2ms，以TTI为0.5ms的帧配置0为例，帧配置0的下行链路的时延为：基站侧的处理时延0.2ms+帧对齐时延1.3ms+用户侧的处理时延0.2ms+一个TTI的时长0.5ms＝2.2ms。
按照同样的方式，可分别确定TTI为0.5ms时帧配置0～6下上行或下行数据传输的时延，如表2所示：
表2
帧配置 0 1 2 3 4 5 6
上行时延(ms) 1.65 2.2 1.3 3.775 4.55 5.425 1.925
下行时延(ms) 2.2 1.65 2.95 1.675 1.4 1.225 1.925

具体实施方式
为了使本发明的目的、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，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
本发明的应用场景如图4和图5所示，应用于载波聚合场景下基站和终端之间的通信，终端可以是移动终端或小站等具有用户功能的设备，基站可以是普通基站或宏站。例如，基站可以是基站收发信台(BTS)、节点B(Node B)、演进的节点B(eNode B或eNB)、家庭基站(Home Node B或HNB)、演进的家庭基站(Home eNode B或HeNB)、中继节点(Relay Node或RN)、无线接入点(AP)、无线路由器以及类似装置等。
本发明实施例中，如图6所示，基站进行载波聚合的具体过程如下：
步骤601：基站确定用于载波聚合的至少两个成员载波中每个成员载波的帧配置。
实施中，至少两个成员载波的帧配置为任意帧配置组合。其中，任意帧配置组合为1msTTI下帧配置0～6的任意组合，或者，任意帧配置组合为0.5msTTI下帧配置0～6的任意组合，或者，任意帧配置组合中包括新定义的各种帧配置。
可选地，用于载波聚合的至少两个成员载波中每个成员载波的帧配置的用于下行数据传输的子帧个数与用于上行数据传输的子帧个数的比值相乘所得的积，与1的差值属于预设范围，该预设范围为预先的设定，例如根据经验值设定为正负0.5的范围，此处仅为举例说明，并不以正负0.5所确定的范围为限制。可选地，用于载波聚合的至少两个成员载波中每个成员载波的帧配置的用于下行数据传输的子帧个数与用于上行数据传输的子帧个数的比值相乘所得的积为1。
例如，用于载波聚合的为两个成员载波CC1和CC2，CC1的帧配置的用 于下行数据传输的子帧个数与用于上行数据传输的子帧个数的比值为6/4，CC2的帧配置的用于下行数据传输的子帧个数与用于上行数据传输的子帧个数的比值为4/6，两个比值的乘积为1。
步骤602：基站确定至少两个成员载波中除参考成员载波之外的每个成员载波相对于参考成员载波的帧开始时间的偏移量，参考成员载波为该至少两个成员载波中的至少一个。
实施中，若定义成员载波相对于参考成员载波的帧开始时间提前或延迟偏移量，则偏移量为大于或等于零的整数。若定义成员载波相对于参考成员载波的帧开始时间偏移该偏移量，则偏移量为整数，定义偏移量大于零时，相对于参考成员载波的帧开始时间定时提前，偏移量小于零时，相对于参考成员载波的帧开始时间定时延迟；或者，定义偏移量大于零时，相对于参考成员载波的帧开始时间定时延迟，偏移量小于零时，相对于参考成员载波的帧开始时间定时提前。其中，帧开始时间的偏移量等于零，表示成员载波与参考成员载波的帧开始时间相同。
实施中，为了降低确定帧配置的复杂度，基站将至少两个成员载波划分为多个载波组，每个载波组包括一个以上的成员载波，分别确定每个载波组中每个成员载波的帧配置。例如，基站确定4个成员载波进行载波聚合，将该4个成员载波划分为两组，每组包括两个成员载波，分别确定每组的两个成员载波对应的帧配置。通过划分载波组的方式进行帧配置，在未进行帧配置的载波组包含的载波数目与已经进行帧配置的载波组包含的载波数目相同的情况下，可以直接使用该已经进行帧配置的载波组中成员载波的帧配置，提高配置效率，降低复杂度。
同理，实施中为了降低确定成员载波相对于参考成员载波的帧开始时间的偏移量的复杂度，基站将至少两个成员载波划分为多个载波组，每个载波组包括一个以上的成员载波，有且仅有一个载波组中包括参考成员载波，对于不包含参考成员载波的载波组，确定该载波组中每个成员载波相对于参考成员载波的帧开始时间的偏移量；对于包含参考成员载波的载波组，确定该 载波组中除参考成员载波之外的每个成员载波相对于该参考成员载波的帧开始时间的偏移量。对于未确定偏移量的第一载波组，若该第一载波组与已经确定偏移量的第二载波组包含相同数目的成员载波，并且第一载波组和第二载波组中相同的成员载波具有相同的帧配置，则第一载波组中成员载波的偏移量可直接使用第二载波组中同一成员载波的偏移量，从而降低复杂度，提高效率，其中第二载波组可以是由载波聚合***中的部分载波组成，也可以是由载波聚合***之外的载波组成。
实施中，在确定偏移量时可能会有不同的方案，例如可以根据如下原则确定偏移量：使得至少两个成员载波在一帧内相同时刻同时具有用于下行数据传输的子帧和用于上行数据传输的子帧的出现次数最多。具体地，基站确定至少两个成员载波中除参考成员载波之外的每个所述成员载波相对于所述参考成员载波的帧开始时间的偏移量的方式有多种，包括但不限于以下所列举的实施方式：
第一实施方式，基站根据每个所述成员载波的帧配置，确定所述至少两个成员载波中除参考成员载波之外的每个所述成员载波相对于所述参考成员载波的帧开始时间的偏移量。
具体地，基站根据每个所述成员载波中用于下行数据传输的子帧的总数与用于上行数据传输的子帧的总数的比值，确定每个所述成员载波相对于参考成员载波的帧开始时间的偏移量。
第二实施方式，所述帧开始时间的偏移量为预设值，所述预设值通过协议约定，或者，由基站从其它设备的配置信令中获得。
可选地，该预设值为所述至少两个所述成员载波中第一个用于下行数据传输的子帧与第一个用于上行数据传输的子帧之间的子帧个数；或者，所述预设值根据一帧内所述至少两个成员载波中同时存在用于上行数据传输的子帧和用于下行数据传输的子帧的次数确定。例如，在两个成员载波的情况下，假设成员载波分CC1和CC2，假设CC1和CC2之间的偏移量为零时，CC1和CC2在一帧内同时存在用于上行数据传输的子帧和用于下行数据传输的子 帧的次数为1次；CC1和CC2之间的偏移量为1时，CC1和CC2在一帧内同时存在用于上行数据传输的子帧和用于下行数据传输的子帧的次数为2；CC1和CC2之间的偏移量为2时，CC1和CC2在一帧内同时存在用于上行数据传输的子帧和用于下行数据传输的子帧的次数为3；CC1和CC2之间的偏移量为3时，CC1和CC2在一帧内同时存在用于上行数据传输的子帧和用于下行数据传输的子帧的次数为6……，依此类推遍历所有可能的偏移量，将得到的CC1和CC2在一帧内同时存在用于上行数据传输的子帧和用于下行数据传输的子帧的次数中的最大值对应的偏移量作为预设值。
第三实施方式，所述帧开始时间的偏移量与参考值的差值在预设范围内，或者，所述偏移量满足在所述至少两个所述成员载波之间的上行子帧不是连续的，相隔时间间隔大于等于载波切换时间。。
可选地，该参考值为所述至少两个所述成员载波中第一个用于下行数据传输的子帧与第一个用于上行数据传输的子帧之间的子帧个数；或者，所述预设值根据一帧内所述至少两个成员载波中同时存在用于上行数据传输的子帧和用于下行数据传输的子帧的次数确定。例如，在两个成员载波的情况下，假设成员载波分CC1和CC2，假设CC1和CC2之间的偏移量为零时，CC1和CC2在一帧内同时存在用于上行数据传输的子帧和用于下行数据传输的子帧的次数为一次；CC1和CC2之间的偏移量为1时，CC1和CC2在一帧内同时存在用于上行数据传输的子帧和用于下行数据传输的子帧的次数为2；CC1和CC2之间的偏移量为2时，CC1和CC2在一帧内同时存在用于上行数据传输的子帧和用于下行数据传输的子帧的次数为3；CC1和CC2之间的偏移量为3时，CC1和CC2在一帧内同时存在用于上行数据传输的子帧和用于下行数据传输的子帧的次数为6……，依此类推遍历所有可能的偏移量，将得到的CC1和CC2在一帧内同时存在用于上行数据传输的子帧和用于下行数据传输的子帧的次数中的最大值对应的偏移量作为参考值。
一个具体实施中，预设至少两个成员载波的帧配置组合与帧开始时间的偏移量或偏移量序列之间的对应关系，将具有相同的帧开始时间的偏移量或 偏移量序列的帧配置组合划分至同一个集合，或者，将包含至少一个相同的成员载波，且该相同的成员载波具有相同的帧配置的帧配置组合划分至同一个集合，基站选择预设的帧配置组合以及帧开始时间的偏移量，具体如下：
第一实施方式，所述基站从预设的帧配置组合的集合中选择一个帧配置组合，帧配置组合中指定位置的帧配置为参考成员载波的帧配置，采用所述帧配置组合中包含的每个帧配置确定每个所述成员载波的帧配置，获取选择的所述帧配置组合对应的帧开始时间的偏移量或偏移量序列，根据获取的帧开始时间的偏移量或偏移量序列，确定除参考成员载波之外的每个所述成员载波相对于所述参考成员载波的帧开始时间的偏移量；
第二实施方式，所述基站获取预设的帧开始时间的偏移量或偏移量序列，根据获取的帧开始时间的偏移量或偏移量序列，确定除参考成员载波之外的每个所述成员载波相对于所述参考成员载波的帧开始时间的偏移量，获取所述帧开始时间的偏移量或偏移量序列对应的帧配置组合的集合，从所述帧配置组合的集合中选择一个帧配置组合，所述帧配置组合中指定位置的帧配置为所述参考成员载波的帧配置，采用选择的帧配置组合中包含的每个帧配置确定每个所述成员载波的帧配置。
其中，若帧配置组合对应的为一个偏移量，则在采用该帧配置组合配置每个成员载波的帧配置的情况下，确定至少两个成员载波中除参考成员载波之外的每个所述成员载波相对于所述参考成员载波的帧开始时间的偏移量相同，为该帧配置组合对应的偏移量；
若帧配置组合对应的为偏移量序列，该偏移量序列与该帧配置组合中除指定所述参考成员载波的帧配置之外的帧配置的排列顺序一致，即在一个成员载波采用该帧配置组合中的帧配置的情况下，则该成员载波相对于参考成员载波的偏移量为偏移量序列中与该帧配置的排列次序对应的偏移量。依次将获取的偏移量序列中的每个偏移量确定为所述至少两个成员载波中除参考成员载波之外的每个所述成员载波相对于所述参考成员载波的帧开始时间的偏移量，以及依次将帧配置组合中的每个帧配置确定为所述至少两个成员载 波的每个所述成员载波的帧配置即可。
可选地，为了实现方便，根据本发明实施例提供的任意一种方式获得一个成员载波相对于参考成员载波的帧开始时间的偏移量后，可设置不同的成员载波相对于所述参考成员载波的帧开始时间的偏移量相同，均为获得的该帧开始时间的偏移量。
可选地，若TTI为1ms，且用于载波聚合的成员载波为两个，两个所述成员载波的帧配置组合可以为以下任意一种：帧配置0与帧配置1的组合，或者，帧配置6与帧配置6的组合，或者，帧配置3与帧配置0的组合，或者，帧配置4与帧配置0的组合，或者，帧配置5与帧配置0的组合，或者，帧配置2与帧配置0的组合；其中，配置0与帧配置1的组合，帧配置6与帧配置6的组合，帧配置3与帧配置0的组合，帧配置4与帧配置0的组合以及帧配置5与帧配置0的组合所对应的帧开始时间的偏移量为2个子帧；帧配置2和帧配置0的组合对应的帧开始时间的偏移量为3个子帧。需要说明的是，此处所列举的帧配置组合以及对应的帧开始时间的偏移量为降低时延效果较好的配置方式，并不排除其它帧配置组合与帧开始时间的偏移量的结合等能够降低时延的配置方式。或者，两个所述成员载波的帧配置组合还可以为以下任意一种：
帧配置1与帧配置1的组合，帧配置1和帧配置1的组合对应的帧开始时间的偏移量为2个子帧；

帧配置6与帧配置6的组合，帧配置6和帧配置6的组合对应的帧开始时间的偏移量为2个子帧或3个子帧；
帧配置3与帧配置0的组合，如果帧配置3为所述第一成员载波，帧配置0为所述第二成员载波，则帧配置3和帧配置0的组合对应的帧开始时间的偏移量为3个子帧；如果帧配置0为所述第一成员载波，帧配置3为所述第二成员载波，则帧配置3和帧配置0的组合对应的帧开始时间的偏移量为2个子帧；
帧配置4与帧配置0的组合，如果帧配置4为所述第一成员载波，帧配置0为所述第二成员载波，则帧配置4和帧配置0的组合对应的帧开始时间的偏移量为3个子帧；如果帧配置0为所述第一成员载波，帧配置4为所述第二成员载波，则帧配置4和帧配置0的组合对应的帧开始时间的偏移量为2个子帧；

步骤603：基站通过该至少两个成员载波与终端通信。
具体实施中，所述基站根据每个所述成员载波的帧配置，确定新的调度时序，按照该新的调度时序与终端通信。为了实现方便，基站根据每个成员载波的帧配置，按照参考调度时序与终端通信，该参考调度时序为任意帧配置的调度时序。该任意帧配置可以是1msTTI下帧配置0～6中的任意一种，或者为0.5msTTI下帧配置0～6中的任意一种，或者为技术人员新定义的一种帧配置。
可选地，为了进一步降低时延，在支持跨载波调度的情况下，基站根据第一成员载波相对于参考成员载波的帧开始时间的偏移量和/或第二成员载波 相对于参考成员载波的偏移量，确定所述第一成员载波相对于所述第二成员载波的帧开始时间提前第一偏移量，第一成员载波的子帧与第二承载载波的子帧之间存在以下调度关系：
a、基站通过第一成员载波中的第一下行子帧调度所述第一成员载波的第二下行子帧，所述第二下行子帧的子帧号与所述第一下行子帧的子帧号相同。
例如，如图7所示，CC1采用帧配置0，CC2采用帧配置1，且CC2相对于CC1的帧开始时间提前偏移量2个子帧，CC2的下行子帧0由CC2的下行子帧0调度。
b、基站通过调度子帧调度所述第一成员载波的第一上行子帧，所述调度子帧为所述第一成员载波的第二下行子帧，所述第一上行子帧的子帧号大于或等于所述第二下行子帧的子帧号加上预设值所得的和值对帧长取模所得的结果，所述帧长为一个无线帧所包含的子帧的个数，也就是说此时第一上行子帧位于第一预设子帧或者位于第一预设子帧之后，其中，所述第一预设子帧的子帧号的值是根据所述第二下行子帧的子帧号与预设值的和值确定的。
例如，如图7所示，CC1采用帧配置0，CC2采用帧配置1，且CC2相对于CC1的帧开始时间提前偏移量2个子帧，CC2的上行子帧2的调度子帧为CC2的子帧6，即满足：CC2的上行子帧2的子帧号2大于或等于CC2的子帧6加上预设值4所得的和值对帧长10取模所得的结果，表示为：2大于或等于((6+4)mod10＝0)，成立。
c、基站通过调度子帧调度所述第一成员载波的第一上行子帧，所述调度子帧为所述第二成员载波的第二下行子帧，所述第一上行子帧的子帧号大于或等于所述第二下行子帧的子帧号加上所述第一偏移量再加上预设值所得的和值对帧长取模所得的结果，所述帧长为一个无线帧所包含的子帧的个数，也就是说所述第一上行子帧位于第二预设子帧或者位于第二预设子帧之后，所述第二预设子帧的子帧号是根据所述第二下行子帧的子帧号加上所述第一偏移量再加上预设值所得的和值确定的。
例如，如图7所示，CC1采用帧配置0，CC2采用帧配置1，且CC2相 对于CC1的帧开始时间提前偏移量2个子帧，CC2的上行子帧2的调度子帧为CC1的子帧6，即满足：CC2的上行子帧2的子帧号大于或等于CC1的子帧6的子帧号6加上偏移量2再加上预设值4所得的和值对帧长10取模所得的结果，表示为：2大于或等于((6+2+4)mod10＝2)，成立。
d、基站通过调度子帧调度所述第二成员载波的第一下行子帧，所述调度子帧为所述第二成员载波的第二下行子帧，所述第二下行子帧的子帧号与所述第一下行子帧的子帧号相同。
例如，如图7所示，CC1采用帧配置0，CC2采用帧配置1，且CC2相对于CC1的帧开始时间提前偏移量2个子帧，CC1的下行子帧0的调度子帧为CC1的下行子帧0，CC1的下行子帧5的调度子帧为CC1的下行子帧5。
e、基站通过调度子帧调度所述第二成员载波的第一下行子帧，所述调度子帧为所述第一成员载波的第二下行子帧，所述第二下行子帧的子帧号等于所述第一下行子帧的子帧号加上所述第一偏移量所得的和值对帧长取模所得的结果，所述帧长为一个无线帧所包含的子帧的个数，也就是说第一下行子帧位于所述第二下行子帧的子帧号减去所述第一偏移量所得的差值所指示的子帧。
例如，如图8所示，CC1采用帧配置6，CC2采用帧配置6，且CC2相对于CC1的帧开始时间提前偏移量2个子帧，CC1的下行子帧9的调度子帧为CC2的子帧1，即满足：调度子帧的子帧号等于CC1的下行子帧的子帧号9加上偏移量2所得的和值对帧长10取模所得的结果，表示为：调度子帧的子帧号等于(9+2)mod10＝1。
f、基站通过调度子帧调度所述第二成员载波的第一上行子帧，所述调度子帧为所述第二成员载波的第二下行子帧，所述第一上行子帧的子帧号大于或等于所述第二下行子帧的子帧号加上预设值所得的和值对帧长取模所得的结果，所述帧长为一个无线帧所包含的子帧的个数，也就是说第一上行子帧位于第三预设子帧或者位于第三预设子帧之后，所述第三预设子帧的子帧号是根据所述第二下行子帧的子帧号加上预设值所得的和值确定的。
例如，如图7所示，CC1采用帧配置0，CC2采用帧配置1，且CC2相对于CC1的帧开始时间提前偏移量2个子帧，CC1的上行子帧2的调度子帧若位于CC1，则调度子帧为CC1的下行子帧6，即满足：CC1的上行子帧2大于或等于调度子帧的子帧号6与预设值4的和值对帧长10取模所得的结果0，表示为：2大于或等于((6+4)mod10＝0)，成立，其中“mod”为取模运算。
g、基站通过调度子帧调度所述第二成员载波的第一上行子帧，所述调度子帧为所述第一成员载波的第二下行子帧，所述第一上行子帧的子帧号大于或等于所述第二下行子帧的子帧号减去所述第一偏移量所得的差加上预设值所得的和值对帧长取模所得的结果，所述帧长为一个无线帧所包含的子帧的个数，也就是说所述第一上行子帧位于第四预设子帧或者位于第四预设子帧之后，第四预设子帧的子帧号是根据所述第二下行子帧的子帧号减去所述第一偏移量所得的差加上预设值所得的和值确定的。
例如，如图7所示，CC1采用帧配置0，CC2采用帧配置1，且CC2相对于CC1的帧开始时间提前偏移量2个子帧，CC1的上行子帧2的调度子帧若位于CC2，则调度子帧为CC2的下行子帧0，即满足：调度子帧的子帧号0大于或等于CC1的上行子帧2的子帧号2加上偏移量2所得的和再减去预设值4所得的差，对帧长10取模所得的结果，表示为：0大于或等于((2+2-4)mod10＝0)，成立，或者，CC1的上行子帧2的子帧号2大于或等于调度子帧的子帧号0减去偏移量2再加上预设值4所得的和对帧长10取模所得结果，表示为：2大于或等于((0-2+4)mod10＝2)。
h.基站通过所述第二成员载波中的第一下行子帧调度所述第一成员载波的第二下行子帧，所述第二下行子帧为所述第一下行子帧的子帧号加上第一偏移量所得的和值所指示的子帧。
以上各调度关系中，若基站通过调度子帧调度所述第一成员载波的第一上行子帧，或者，所述基站通过调度子帧调度所述第二成员载波的第一上行子帧，所述调度子帧为所述第一成员载波和所述第二成员载波中距离所述第一上行子帧最近的下行子帧。
其中，若第一成员载波和第二成员载波均属于用于载波聚合的成员载波，但均不是参考成员载波，则基站根据第一成员载波相对于所述参考成员载波的帧开始时间的偏移量以及第二成员载波相对于所述参考成员载波的偏移量，确定所述第一成员载波相对于所述第二成员载波的帧开始时间提前第一偏移量。
若第二成员载波为参考成员载波，则基站根据第一成员载波相对于参考成员载波的帧开始时间的偏移量，确定所述第一成员载波相对于第二成员载波的帧开始时间提前第一偏移量，该第一偏移量为所述第一成员载波相对于所述参考成员载波的帧开始时间提前的偏移量。
若第一成员载波为参考成员载波，则基站根据第二成员载波相对于参考成员载波的帧开始时间的偏移量，确定所述第一成员载波相对于第二成员载波的帧开始时间提前第一偏移量，该第一偏移量为第二成员载波相对于参考成员载波的帧开始时间延迟的偏移量。
具体地，若第一成员载波和第二成员载波均不是参考成员载波，第一成员载波相对于参考成员载波提前偏移量a，第二成员载波相对于参考成员载波提前偏移量b，且b<a，确定第一成员载波相对于第二成员载波的帧开始时间提前偏移量为a-b所得差；若第一成员载波和第二成员载波均不是参考成员载波，第一成员载波相对于参考成员载波提前偏移量a，第二成员载波相对于参考成员载波延迟偏移量b，确定第一成员载波相对于第二成员载波的帧开始时间提前偏移量为a+b所得和；若第一成员载波和第二成员载波均不是参考成员载波，第一成员载波相对于参考成员载波延迟偏移量a，第二成员载波相对于参考成员载波延迟偏移量b，且b>a，确定第一成员载波相对于第二成员载波的帧开始时间提前偏移量为b-a所得差。
基于同一发明构思，本发明实施例中，如图9所示，终端进行载波聚合的过程如下：
步骤901：终端接收基站发送的至少两个用于载波聚合的成员载波的帧配置。
步骤902：终端获取至少两个成员载波中除参考成员载波之外的每个所述成员载波相对于所述参考成员载波的帧开始时间的偏移量，所述参考成员载波为所述至少两个成员载波中的至少一个。
实施中，若定义成员载波相对于参考成员载波的帧开始时间提前或延迟偏移量，则偏移量为大于或等于零的整数。若定义成员载波相对于参考成员载波的帧开始时间偏移该偏移量，则偏移量为整数，定义偏移量大于零时，相对于参考成员载波的帧开始时间定时提前，偏移量小于零时，相对于参考成员载波的帧开始时间定时延迟；或者，定义偏移量大于零时，相对于参考成员载波的帧开始时间定时延迟，偏移量小于零时，相对于参考成员载波的帧开始时间定时提前。其中，帧开始时间的偏移量等于零，表示成员载波与参考成员载波的帧开始时间相同。
实施中，终端获取除参考成员载波之外的每个所述成员载波相对于所述参考成员载波的帧开始时间的偏移量的方式包括但不限于以下两种：
第一种，终端接收所述基站发送的所述至少两个成员载波中除参考成员载波之外的每个所述成员载波相对于所述参考成员载波的帧开始时间的偏移量；
第二种，终端通过检测每个所述成员载波的同步信号，确定所述至少两个成员载波中除参考成员载波之外的每个所述成员载波相对于所述参考成员载波的帧开始时间的偏移量。
步骤903：终端通过所述至少两个成员载波与所述基站通信。
以下以两个成员载波为例，分析如何通过设置成员载波的帧配置和帧开始时间的偏移量降低时延。
第一～第六以及第十三～十五具体实施例中，假设TTI为1ms,下行链路的基站侧的处理时延为1ms，上行链路的用户侧的处理时延为1.5ms。
第一具体实施例中，假设成员载波CC1采用帧配置0，成员载波CC2采用帧配置1，且CC2相对于CC1提前2个子帧，即帧开始时间的偏移量为2个子帧，如图7所示为帧配置0和帧配置1的载波聚合示意图。
该第一具体实施例中，帧对齐时延的计算过程如下：
下行链路：
如果下行数据在CC2的子帧0到达，在CC2的子帧1发送，假设在CC2的子帧0内需要等待TTI的一半时长，则时延为0.5ms；
以下同理，如果下行数据在CC2的子帧1到达，在CC1的子帧0发送，时延为0.5ms；
如果下行数据在CC2的子帧2到达，在CC1的子帧1发送，时延为0.5ms；
如果下行数据在CC2的子帧3到达，在CC2的子帧4发送，时延为0.5ms；
如果下行数据在CC2的子帧4到达，在CC2的子帧5发送，时延为0.5ms；
如果下行数据在CC2的子帧5到达，在CC2的子帧6发送，时延为0.5ms；
如果下行数据在CC2的子帧6到达，在CC1的子帧5发送，时延为0.5ms；
如果下行数据在CC2的子帧7到达，在CC1的子帧6发送，时延为0.5ms；
如果下行数据在CC2的子帧8到达，在CC2的子帧9发送，时延为0.5ms；
如果下行数据在CC2的子帧9到达，在CC2的子帧0发送，时延为0.5ms；
因此，载波聚合的下行链路的帧对齐时延为以上下行数据传输时延的平均值，即0.5ms，下行的总时延为：基站侧的处理时延1.5ms+帧对齐时延0.5ms+用户侧的处理时延1ms+一个TTI的时长1ms＝4ms。
上行链路：
如果上行数据在CC1的子帧0到达，在CC2的子帧3发送，假设在CC1的子帧0内需要等待TTI一半的时长，则时延为0.5ms；
以下同理，如果上行数据在CC1的子帧1到达，在CC1的子帧2发送，时延为0.5ms；
如果上行数据在CC1的子帧2到达，在CC1的子帧3发送，时延为0.5ms；
如果上行数据在CC1的子帧3到达，在CC1的子帧4发送，时延为0.5ms；
如果上行数据在CC1的子帧4到达，在CC2的子帧7发送，时延为0.5ms；
如果上行数据在CC1的子帧5到达，在CC2的子帧8发送，时延为0.5ms；
如果上行数据在CC1的子帧6到达，在CC1的子帧7发送，时延为0.5ms；
如果上行数据在CC1的子帧7到达，在CC1的子帧8发送，时延为0.5ms；
如果上行数据在CC1的子帧8到达，在CC1的子帧9发送，时延为0.5ms；
如果上行数据在CC1的子帧9到达，在CC2的子帧2发送，时延为0.5ms；
因此，载波聚合的上行链路的帧对齐时延为以上上行数据传输的时延的平均值，即0.5ms，上行的总时延为：基站侧的处理时延1.5ms+帧对齐时延0.5ms+用户侧的处理时延1ms+一个TTI的时长1ms＝4ms。
该第一具体实施例中，CC1和CC2的调度关系如下：

该第五具体实施例中，在支持跨载波调度的情况下，调度关系如下：
CC1:CC1的子帧0由CC1的子帧0调度，CC1的子帧1由CC1的子帧1调度，CC1的子帧2由CC2的子帧0或CC1的子帧8调度，CC1的子帧3 由CC2的子帧1或CC1的子帧9调度，CC1的子帧4由CC1的子帧4或CC2的子帧6调度，CC1的子帧5由CC1的子帧5调度，CC1的子帧6由CC1的子帧6调度，CC1的子帧7由CC1的子帧7调度，CC1的子帧8由CC1的子帧8或CC2的子帧0调度，CC1的子帧9由CC1的子帧9或CC2的子帧1调度。

第六具体实施例中，假设成员载波CC1采用帧配置5，成员载波CC2采用帧配置0，且CC2相对于CC1提前0个或2个子帧，或者，CC1相对于CC2延迟0个或2个子帧，如图13所示为CC2相对于CC1提前0个子帧时帧配置5和帧配置0的载波聚合示意图。与第一具体实施例中的分析过程相同，该第六具体实施例中载波聚合的下行的总时延为4.1ms，载波聚合上行的总时延为4.6ms。
在支持跨载波调度的情况下，调度关系如下：

第一～第六具体实施例中所提供的两个成员载波的帧配置组合可以根据帧开始时间的偏移量offset划分为多个集合，将具有相同的帧开始时间的偏移量的帧配置组合划分到同一个集合中，得到两个集合，分别表示如下：

Figure PCTCN2016094918-appb-000002
在第七～第十二以及第十六～第二十具体实施例中，假设TTI为0.5ms,并且假设基站侧的处理时延为0.2ms，用户侧的处理时延为0.2ms。
第七具体实施例中，假设成员载波CC1采用帧配置0，成员载波CC2采用帧配置1，且CC2相对于CC1提前4个子帧，或者CC1相对于CC2延迟4个子帧，即帧开始时间的偏移量为4个子帧，如图14所示为0.5msTTI的帧配置0和帧配置1的载波聚合示意图，其中，0～9为每半帧包含的子帧，每个子帧为0.5ms。
下行链路：
如果下行数据在CC2的子帧0到达，在CC2的子帧1发送，假设在CC2的子帧0内需要等待TTI的一半时长，时延为0.25ms；
以下同理，如果下行数据在CC2的子帧1到达，在CC2的子帧2发送，时延为0.25ms；
如果下行数据在CC2的子帧2到达，在CC2的子帧3发送，时延为0.25ms；
如果下行数据在CC2的子帧3到达，在CC1的子帧0发送，时延为0.25ms；
如果下行数据在CC2的子帧4到达，在CC1的子帧1发送，时延为0.25ms；
如果下行数据在CC2的子帧5到达，在CC1的子帧2发送，时延为0.25ms；
如果下行数据在CC2的子帧6到达，在CC1的子帧3发送，时延为0.25ms；
如果下行数据在CC2的子帧7到达，在CC2的子帧8发送，时延为0.25ms；
如果下行数据在CC2的子帧8到达，在CC2的子帧9发送，时延为0.25ms；
如果下行数据在CC2的子帧9到达，在CC2的子帧0发送，时延为0.25ms；
因此，载波聚合的下行链路的帧对齐时延为以上下行数据传输时延的平均值，即0.25ms，下行的总时延为：基站侧的处理时延0.2ms+帧对齐时延0.25ms+用户侧的处理时延0.2ms+一个TTI的时长0.5ms＝1.15ms。
上行链路：
如果上行数据在CC2的子帧0到达，在CC2的子帧4发送，假设在CC1的子帧0内需要等待TTI一半的时长，即0.25ms，时延为：0.25ms+3个子帧的时长1.5ms＝1.75ms；
以下同理，如果上行数据在CC2的子帧1到达，在CC2的子帧4发送，时延为1.25ms；
如果上行数据在CC2的子帧2到达，在CC2的子帧4发送，时延为0.75ms；
如果上行数据在CC2的子帧3到达，在CC2的子帧4发送，时延为0.25ms；
如果上行数据在CC2的子帧4到达，在CC2的子帧5发送，时延为0.25ms；
如果上行数据在CC2的子帧5到达，在CC2的子帧6发送，时延为0.25ms；
如果上行数据在CC2的子帧6到达，在CC2的子帧7发送，时延为0.25ms；
如果上行数据在CC2的子帧7到达，在CC1的子帧4发送，时延为0.25ms；
如果上行数据在CC2的子帧8到达，在CC1的子帧5发送，时延为0.25ms；
如果上行数据在CC2的子帧9到达，在CC1的子帧6发送，时延为0.25ms；
因此，载波聚合的上行链路的帧对齐时延为以上上行数据传输的时延的平均值，即0.55ms，上行的总时延为：基站侧的处理时延0.2ms+帧对齐时延0.55ms+用户侧的处理时延0.2ms+一个TTI的时长0.5ms＝1.45ms。
在支持跨载波调度的情况下，调度关系如下：

其中，若第一成员载波和第二成员载波均属于用于载波聚合的成员载波，但均不是参考成员载波，则通信模块根据第一成员载波相对于所述参考成员载波的帧开始时间的偏移量以及第二成员载波相对于所述参考成员载波的偏移量，确定所述第一成员载波相对于所述第二成员载波的帧开始时间提前第一偏移量。
若第二成员载波为参考成员载波，则通信模块根据第一成员载波相对于参考成员载波的帧开始时间的偏移量，确定所述第一成员载波相对于第二成员载波的帧开始时间提前第一偏移量，该第一偏移量为所述第一成员载波相 对于所述参考成员载波的帧开始时间提前的偏移量。

具体地，若第一成员载波和第二成员载波均不是参考成员载波，第一成员载波相对于参考成员载波提前偏移量a，第二成员载波相对于参考成员载波提前偏移量b，且b<a，确定第一成员载波相对于第二成员载波的帧开始时间提前偏移量为a-b所得差；若第一成员载波和第二成员载波均不是参考成员载波，第一成员载波相对于参考成员载波提前偏移量a，第二成员载波相对于参考成员载波延迟偏移量b，确定第一成员载波相对于第二成员载波的帧开始时间提前偏移量为a+b所得和；若第一成员载波和第二成员载波均不是参考成员载波，第一成员载波相对于参考成员载波延迟偏移量a，第二成员载波相对于参考成员载波延迟偏移量b，且b>a，确定第一成员载波相对于第二成员载波的帧开始时间提前偏移量为b-a所得差。
实施中，在确定偏移量时可能会有不同的方案，例如可以根据如下原则确定偏移量：使得至少两个成员载波在一帧内相同时刻同时具有用于下行数据传输的子帧和用于上行数据传输的子帧的出现次数最多。具体地，第二确定模块确定至少两个成员载波中除参考成员载波之外的每个所述成员载波相对于所述参考成员载波的帧开始时间的偏移量的方式有多种，包括但不限于以下所列举的实施方式：
第一种，根据每个所述成员载波的帧配置，确定所述至少两个成员载波中除参考成员载波之外的每个所述成员载波相对于所述参考成员载波的帧开始时间的偏移量。
第二种，所述帧开始时间的偏移量为预设值，所述预设值通过协议约定或信令配置得到。
第三种，所述帧开始时间的偏移量与参考值的差值在预设范围内。
第二种或第三种实施方式中，所述预设值或所述参考值为所述至少两个所述成员载波中第一个用于下行数据传输的子帧与第一个用于上行数据传输的子帧之间的子帧个数；
或者，
所述预设值或所述参考值根据一帧内所述至少两个成员载波中同时存在用于上行数据传输的子帧和用于下行数据传输的子帧的次数确定。
可选地，为了实现方便，根据本发明实施例提供的任意一种方式获得一个成员载波相对于参考成员载波的帧开始时间的偏移量后，可设置不同的成员载波相对于所述参考成员载波的帧开始时间的偏移量相同，均为获得的该帧开始时间的偏移量。
可选地，若传输时间间隔TTI为1毫秒，且用于载波聚合的成员载波为两个，两个所述成员载波的帧配置组合为：帧配置0与帧配置1的组合，或者，帧配置6与帧配置6的组合，或者，帧配置3与帧配置0的组合，或者，帧配置4与帧配置0的组合，或者，帧配置5与帧配置0的组合，或者，帧配置2与帧配置0的组合；
其中，配置0与帧配置1的组合，帧配置6与帧配置6的组合，帧配置3与帧配置0的组合，帧配置4与帧配置0的组合以及帧配置5与帧配置0的组合所对应的帧开始时间的偏移量为2个子帧；帧配置2和帧配置0的组合对应的帧开始时间的偏移量为3个子帧。需要说明的是，此处所列举的帧配置组合以及对应的帧开始时间的偏移量为降低时延效果较好的配置方式，并不排除其它帧配置组合与帧开始时间的偏移量的结合等能够降低时延的配置方式。
可选地，若传输时间间隔TTI为0.5毫秒，且用于载波聚合的成员载波为两个，两个所述成员载波的帧配置组合为：帧配置0与帧配置1的组合，或者，帧配置3与帧配置0的组合，或者，帧配置2与帧配置0的组合，或者，帧配置4与帧配置0的组合，或者，帧配置5与帧配置0的组合，或者，帧配置6与帧配置6的组合；
其中，帧配置0与帧配置1的组合以及帧配置3与帧配置0的组合所对应的帧开始时间的偏移量为4个子帧；帧配置2与帧配置0的组合，帧配置4与帧配置0的组合，帧配置5与帧配置0的组合以及帧配置6与帧配置6的组合所对应的帧开始时间的偏移量为6个子帧。需要说明的是，此处所列举的帧配置组合以及对应的帧开始时间的偏移量为降低时延效果较好的配置方式，并不排除其它帧配置组合与帧开始时间的偏移量的结合等能够降低时延的配置方式。
实施中，所述至少两个成员载波的帧配置为任意帧配置的组合。其中，任意帧配置组合为1msTTI下帧配置0～6的任意组合，或者，任意帧配置组合为0.5msTTI下帧配置0～6的任意组合，或者，任意帧配置组合中包括新定义的各种帧配置。
实施中，为了降低确定帧配置的复杂度，用于载波聚合的至少两个成员载波由两个以上载波组组成，每个载波组包含一个以上成员载波，所述第一确定模块具体用于：
分别确定每个载波组中的成员载波的帧配置。通过划分载波组的方式进行帧配置，在未进行帧配置的载波组包含的载波数目与已经进行帧配置的载波组包含的载波数目相同的情况下，可以直接使用该已经进行帧配置的载波组中成员载波的帧配置，提高配置效率，降低复杂度。
同理，实施中为了降低确定成员载波相对于参考成员载波的帧开始时间的偏移量的复杂度，第二确定模块具体用于：分别确定每个载波组的除所述参考成员载波之外的每个成员载波相对于所述参考成员载波的帧开始时间的偏移量，有且仅有一个所述载波组中包含所述参考成员载波。第二确定模块对于不包含参考成员载波的载波组，确定该载波组中每个成员载波相对于参考成员载波的帧开始时间的偏移量；对于包含参考成员载波的载波组，确定该载波组中除参考成员载波之外的每个成员载波相对于该参考成员载波的帧开始时间的偏移量。对于未确定偏移量的第一载波组，若该第一载波组与已经确定偏移量的第二载波组包含相同数目的成员载波，并且第一载波组和第 二载波组中相同的成员载波具有相同的帧配置，则第一载波组中成员载波的偏移量可直接使用第二载波组中同一成员载波的偏移量，从而降低复杂度，提高效率。
一个具体实施中，预设至少两个成员载波的帧配置组合与帧开始时间的偏移量或偏移量序列之间的对应关系，将具有相同的帧开始时间的偏移量或偏移量序列的帧配置组合划分至同一个集合，或者，将包含至少一个相同的成员载波，且该相同的成员载波具有相同的帧配置的帧配置组合划分至同一个集合，第一确定模块选择帧配置组合以及第二确定模块选择帧开始时间的偏移量或偏移量序列，具体如下：
从预设的帧配置组合的集合中选择一个帧配置组合，帧配置组合中指定位置的帧配置为参考成员载波的帧配置，采用所述帧配置组合中包含的每个帧配置确定每个所述成员载波的帧配置，获取选择的所述帧配置组合对应的帧开始时间的偏移量或偏移量序列，根据获取的帧开始时间的偏移量或偏移量序列确定所述至少两个成员载波中除参考成员载波之外的每个所述成员载波相对于所述参考成员载波的帧开始时间的偏移量，其中，对应相同的帧开始时间的偏移量或偏移量序列的帧配置组合属于同一个集合，或者包含有至少一个相同的成员载波，且所述相同的成员载波具有相同的帧配置的帧配置组合属于同一个集合；
或者，
获取预设的帧开始时间的偏移量或偏移量序列，根据获取的帧开始时间的偏移量或偏移量序列，确定所述至少两个成员载波中除参考成员载波之外的每个所述成员载波相对于所述参考成员载波的帧开始时间的偏移量，获取所述帧开始时间的偏移量或偏移量序列对应的帧配置组合的集合，从所述帧配置组合的集合中选择一个帧配置组合，所述帧配置组合中指定位置的帧配置为所述参考成员载波的帧配置，采用选择的帧配置组合中包含的每个帧配置确定每个所述成员载波的帧配置，其中，对应相同的帧开始时间的偏移量或偏移量序列的帧配置组合属于同一个集合，或者包含有至少一个相同的成 员载波，且所述相同的成员载波具有相同的帧配置的帧配置组合属于同一个集合。
其中，若帧配置组合对应的为一个偏移量，则在采用该帧配置组合配置每个成员载波的帧配置的情况下，确定至少两个成员载波中除参考成员载波之外的每个所述成员载波相对于所述参考成员载波的帧开始时间的偏移量相同，为该帧配置组合对应的偏移量；
若帧配置组合对应的为偏移量序列，该偏移量序列与该帧配置组合中除指定所述参考成员载波的帧配置之外的帧配置的排列顺序一致，即在一个成员载波采用该帧配置组合中的帧配置的情况下，则该成员载波相对于参考成员载波的偏移量为偏移量序列中与该帧配置的排列次序对应的偏移量。依次将获取的偏移量序列中的每个偏移量确定为所述至少两个成员载波中除参考成员载波之外的每个所述成员载波相对于所述参考成员载波的帧开始时间的偏移量，以及依次将帧配置组合中的每个帧配置确定为所述至少两个成员载波的每个所述成员载波的帧配置即可。
具体实施中，通信模块根据每个所述成员载波的帧配置，确定新的调度时序，按照该新的调度时序与终端通信。为了实现方便，通信模块根据每个成员载波的帧配置，按照参考调度时序与终端通信，该参考调度时序为任意帧配置的调度时序。该任意帧配置可以是1msTTI下帧配置0～6中的任意一种，或者为0.5msTTI下帧配置0～6中的任意一种，或者为技术人员新定义的一种帧配置。
可选地，用于载波聚合的至少两个成员载波中每个成员载波的帧配置的用于下行数据传输的子帧个数与用于上行数据传输的子帧个数的比值相乘所得的积，与1的差值属于预设范围，该预设范围为预先的设定，例如根据经验值设定为正负0.5的范围，此处仅为举例说明，并不以正负0.5所确定的范围为限制。可选地，用于载波聚合的至少两个成员载波中每个成员载波的帧配置的用于下行数据传输的子帧个数与用于上行数据传输的子帧个数的比值相乘所得的积为1。
