- Step 602 The base station determines an offset of a frame start time of each component carrier of the at least two component carriers except the reference component carrier, where the reference component carrier is at least one of the at least two component carriers. .
- the offset is an integer greater than or equal to zero. If the frame start time of the component carrier is offset from the reference component carrier by the offset, the offset is an integer, and when the offset is greater than zero, the frame start time timing is advanced relative to the reference component carrier, and the offset is When less than zero, the frame start time timing delay relative to the reference component carrier; or, when the offset is greater than zero, the frame start time timing delay relative to the reference component carrier, when the offset is less than zero, relative to the reference component carrier The frame start time is advanced.

- the preset value is determined according to the number of times that the subframe for uplink data transmission and the subframe for downlink data transmission exist simultaneously in the at least two component carriers in one frame.

Description
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。The present invention relates to the field of communications technologies, and in particular, to a carrier aggregation method and device.
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。As the number of intelligent terminal users increases, user traffic and data throughput increase, higher requirements are placed on communication rates. Moreover, due to the shortage of wireless spectrum resources, it is difficult to find continuous large bandwidth for mobile communication. Based on this, a carrier aggregation technology is introduced in the Long Term Evolution-Advanced (LTE-A), that is, multiple continuous or discontinuous spectrum aggregation is used to solve the demand for large bandwidth of mobile communication, and the wireless frequency band is improved. Utilization of scattered spectrum resources.
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。In the carrier aggregation scenario shown in FIG. 1, the terminal simultaneously communicates with the base station through two component carriers CC1 and CC2. In fact, LTE-A can support aggregation of no more than five component carriers.
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。At present, there are some applications that require low latency, such as interactive games, intelligent transportation, etc., which place high demands on the delay of wireless communication. Therefore, how to reduce the delay becomes a key issue in communication.
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。At present, the delay is mainly reduced by reducing the Transmission Time Interval (TTI).
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。The frame configuration in this document refers to the number of uplink subframes, downlink subframes, and special subframes included in a radio frame, and the relationship between uplink, downlink, and special subframes. The special subframes must include guard time, and may also include Upstream and/or downstream.
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。Each TTI of LTE is 1 millisecond (ms), and the delay values corresponding to different frame configurations are different, assuming that the processing delay of the uplink base station side is 1.5 ms, and the processing delay of the user side is 1 ms, and the downlink base station side is The processing delay is 1 ms, and the processing delay on the user side is 1.5 ms. The frame alignment delay value is different in different frame configurations. The frame alignment time refers to the waiting time between when the service arrives and when the service can obtain the transmission opportunity of the air interface subframe. The frame configuration 0 is taken as an example. The frame structure corresponding to the frame configuration 0 is as shown in FIG. 2. In the downlink data transmission, when the TTI is 1 ms, the downlink delay of the frame configuration 0 of the LTE is:
The processing delay on the station side is 1 ms + the frame alignment delay is 1.7 ms + the processing delay on the user side is 1.5 ms + the duration of one TTI is 1 ms = 5.2 ms.
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:In the same manner, the delay of the uplink or downlink data transmission in the frame configuration 0 to 6 when the TTI is 1 ms can be determined separately, as shown in Table 1:
表1Table 1
LTE的帧配置 |

上行时延(ms)Uplink delay (ms) | 4.64.6 | 5.25.2 | 66 | 6.86.8 | 7.67.6 | 8.58.5 | 4.94.9 |

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。The LTE-compatible 1 ms downlink subframe is divided into two 0.5 ms downlink subframes, and the LTE 1 ms special subframe is divided into one. A downlink subframe of 0.5 ms and a special subframe of 0.5 ms, the uplink subframe of 1 ms of LTE is divided into two uplink subframes of 0.5 ms, and the structure of the frame configuration with a TTI of 0.5 ms is shown in FIG. .
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。It is assumed that the processing delay of the base station side is 0.2 ms, the processing delay of the user side is 0.2 ms, and the frame configuration 0 with the TTI of 0.5 ms is taken as an example, and the delay of the downlink of the frame configuration 0 is: when processing on the base station side Delay 0.2ms + frame alignment delay 1.3ms + user side processing delay 0.2ms + one TTI duration 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:In the same manner, the delay of the uplink or downlink data transmission in the frame configuration 0 to 6 when the TTI is 0.5 ms can be separately determined, as shown in Table 2:

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。Step 602: The base station determines an offset of a frame start time of each component carrier of the at least two component carriers except the reference component carrier, where the reference component carrier is at least one of the at least two component carriers. .
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。In the implementation, if the frame start time advance or delay offset of the component carrier relative to the reference component carrier is defined, the offset is an integer greater than or equal to zero. If the frame start time of the component carrier is offset from the reference component carrier by the offset, the offset is an integer, and when the offset is greater than zero, the frame start time timing is advanced relative to the reference component carrier, and the offset is When less than zero, the frame start time timing delay relative to the reference component carrier; or, when the offset is greater than zero, the frame start time timing delay relative to the reference component carrier, when the offset is less than zero, relative to the reference component carrier The frame start time is advanced. The offset of the frame start time is equal to zero, indicating that the frame carrier and the reference component carrier have the same frame start time.
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。In the implementation, in order to reduce the complexity of determining the frame configuration, the base station divides at least two component carriers into multiple carrier groups, each carrier group includes one or more component carriers, and respectively determines frames of each component carrier in each carrier group. Configuration. For example, the base station determines four component carriers for carrier aggregation, and divides the four component carriers into two groups, each group includes two component carriers, and respectively determines a frame configuration corresponding to two component carriers of each group. The frame configuration is performed by dividing the carrier group. If the number of carriers included in the carrier group that has not been frame-configured is the same as the number of carriers included in the carrier group that has been frame-configured, the carrier group that has been frame-configured can be directly used. The frame configuration of the medium component carrier improves configuration efficiency and reduces complexity.
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系统中的部分载波组成,也可以是由载波聚合系统之外的载波组成。Similarly, in order to reduce the complexity of determining the offset of the component carrier relative to the frame start time of the reference component carrier, the base station divides at least two component carriers into multiple carrier groups, each carrier group including more than one member. a carrier, one and only one carrier group includes a reference component carrier, and for a carrier group not including the reference component carrier, determining an offset of a frame start time of each component carrier in the carrier group with respect to a reference component carrier; Refer to the carrier group of the component carrier to determine the
The offset of the frame start time of each component carrier other than the reference component carrier relative to the frame start time of the reference component carrier. For the first carrier group for which the offset is not determined, if the first carrier group includes the same number of component carriers as the second carrier group for which the offset has been determined, and the same member in the first carrier group and the second carrier group If the carriers have the same frame configuration, the offset of the component carriers in the first carrier group can directly use the offset of the same component carrier in the second carrier group, thereby reducing complexity and improving efficiency, wherein the second carrier group can be It consists of a part of carriers in the carrier aggregation system, and may also be composed of carriers other than the carrier aggregation system.
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:In an implementation, there may be different schemes when determining the offset. For example, the offset may be determined according to the following principle: at least two component carriers have both subframes for downlink data transmission and at the same time in one frame. The subframes for uplink data transmission have the most occurrences. Specifically, the base station determines, in the manner of the offset of the frame start time of each of the at least two component carriers, other than the reference component carrier, with respect to the frame start time of the reference component carrier, including but not limited to the following The enumerated implementations:
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。a first embodiment, the base station determines, according to a frame configuration of each of the component carriers, a frame start time of each of the at least two component carriers except the reference component carrier with respect to the reference component carrier The offset.
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。Specifically, the base station determines, according to a ratio of a total number of subframes for downlink data transmission in each of the component carriers to a total number of subframes used for uplink data transmission, a frame of each of the component carriers relative to a reference component carrier. The offset of the start time.
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。In the second implementation manner, the offset of the frame start time is a preset value, and the preset value is agreed by a protocol, or is obtained by a base station from configuration signaling of other devices.
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。Optionally, the preset value is a number of subframes between a first one of the at least two component carriers used for downlink data transmission and a first one used for uplink data transmission; Or the preset value is determined according to the number of times that the subframe for uplink data transmission and the subframe for downlink data transmission exist simultaneously in the at least two component carriers in one frame. For example, in the case of two component carriers, assuming that the component carriers are divided into CC1 and CC2, assuming that the offset between CC1 and CC2 is zero, CC1 and CC2 have both subframes for uplink data transmission in one frame. And for sub-data transmission
The number of frames is 1; when the offset between CC1 and CC2 is 1, CC1 and CC2 have both the subframe for uplink data transmission and the subframe for downlink data transmission in one frame. When the offset between CC1 and CC2 is 2, the number of times that CC1 and CC2 have both a subframe for uplink data transmission and a subframe for downlink data transmission in one frame is 3; between CC1 and CC2 When the offset is 3, CC1 and CC2 have both the subframe for uplink data transmission and the subframe for downlink data transmission in a frame of 6..., and so on, traverse all possible offsets. For the obtained CC1 and CC2, the offset corresponding to the maximum value of the number of times of the subframe for uplink data transmission and the subframe for downlink data transmission is simultaneously present as a preset value in one frame.
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。。In a third implementation manner, the difference between the offset of the frame start time and the reference value is within a preset range, or the offset satisfies an uplink subframe between the at least two component carriers Not continuous, the interval is greater than or equal to the carrier switching time. .
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。Optionally, the reference value is a number of subframes between a subframe that is used by the first one of the at least two of the component carriers for downlink data transmission and a subframe that is used for uplink data transmission; or The preset value is determined according to the number of times that the subframe for uplink data transmission and the subframe for downlink data transmission exist simultaneously in the at least two component carriers in one frame. For example, in the case of two component carriers, assuming that the component carriers are divided into CC1 and CC2, assuming that the offset between CC1 and CC2 is zero, CC1 and CC2 have both subframes for uplink data transmission in one frame. And the number of times of the subframe used for downlink data transmission is once; when the offset between CC1 and CC2 is 1, CC1 and CC2 have both subframes for uplink data transmission and downlink data transmission in one frame. The number of times of the subframe is 2; when the offset between CC1 and CC2 is 2, the number of times that CC1 and CC2 have both the subframe for uplink data transmission and the subframe for downlink data transmission in one frame is 3; When the offset between CC1 and CC2 is 3, CC1 and CC2 have both the subframe for uplink data transmission and the subframe for downlink data transmission in a frame of 6..., according to this The analogy traverses all possible offsets, and the obtained CC1 and CC2 have the offset corresponding to the maximum value of the number of times of the subframe for the uplink data transmission and the subframe for the downlink data transmission in one frame as Reference.

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;For the same reason, if the downlink data arrives in subframe 1 of CC2 and is transmitted in subframe 0 of CC1, the delay is 0.5 ms;
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;If the downlink data arrives in subframe 2 of CC2, and is transmitted in subframe 1 of CC1, the delay is 0.5 ms;
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;If the downlink data arrives in subframe 3 of CC2, and is transmitted in subframe 4 of CC2, the delay is 0.5 ms;
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;If the downlink data arrives in subframe 4 of CC2, and is transmitted in subframe 5 of CC2, the delay is 0.5 ms;

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;If the uplink data arrives in subframe 3 of CC1, and is transmitted in subframe 4 of CC1, the delay is 0.5 ms;
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;If the uplink data arrives in subframe 4 of CC1, and is transmitted in subframe 7 of CC2, the delay is 0.5 ms;
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;If the uplink data arrives in subframe 5 of CC1, and is transmitted in subframe 8 of CC2, the delay is 0.5 ms;
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;
If the uplink data arrives in subframe 6 of CC1, and is transmitted in subframe 7 of CC1, the delay is 0.5 ms;
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;If the uplink data arrives in subframe 7 of CC1, and is transmitted in subframe 8 of CC1, the delay is 0.5 ms;
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;If the uplink data arrives in subframe 8 of CC1, and is transmitted in subframe 9 of CC1, the delay is 0.5 ms;
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;If the uplink data arrives in subframe 9 of CC1 and is transmitted in subframe 2 of CC2, the delay is 0.5 ms;
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。Therefore, the frame alignment delay of the uplink of the carrier aggregation is the average of the delay of the uplink data transmission, that is, 0.5 ms, and the total delay of the uplink is: the processing delay of the base station side is 1.5 ms + the frame alignment delay is 0.5 ms+ The processing delay on the user side is 1 ms + the duration of one TTI is 1 ms = 4 ms.

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。
In the seventh embodiment, it is assumed that the component carrier CC1 adopts frame configuration 0, the component carrier CC2 adopts frame configuration 1, and CC2 advances 4 subframes with respect to CC1, or CC1 delays 4 subframes with respect to CC2, that is, the frame start time is biased.

下行链路:Downlink:
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;If the downlink data arrives in subframe 0 of CC2 and is transmitted in subframe 1 of CC2, it is assumed that half of the duration of the TTI needs to be waited in subframe 0 of CC2, and the delay is 0.25 ms;
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;For the same reason, if the downlink data arrives in subframe 1 of CC2 and is transmitted in subframe 2 of CC2, the delay is 0.25 ms;
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;If the downlink data arrives in subframe 2 of CC2, and is transmitted in subframe 3 of CC2, the delay is 0.25 ms;
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;If the downlink data arrives in subframe 3 of CC2, and is transmitted in subframe 0 of CC1, the delay is 0.25 ms;
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;If the downlink data arrives in subframe 4 of CC2, and is transmitted in subframe 1 of CC1, the delay is 0.25 ms;
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;If the downlink data arrives in subframe 5 of CC2, and is transmitted in subframe 2 of CC1, the delay is 0.25 ms;

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。Therefore, the frame alignment delay of the downlink of the carrier aggregation is the average value of the downlink data transmission delay, that is, 0.25 ms, and the total delay of the downlink is: the processing delay of the base station side is 0.2 ms + the frame alignment delay is 0.25 ms + the user The processing delay of the side is 0.2 ms + the duration of one TTI is 0.5 ms = 1.15 ms.
上行链路:Uplink:

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;For the same reason, if the uplink data arrives in subframe 1 of CC2 and is transmitted in subframe 4 of CC2, the delay is 1.25 ms;
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;If the uplink data arrives in subframe 2 of CC2 and is transmitted in subframe 4 of CC2, the delay is 0.75 ms;
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;If the uplink data arrives in subframe 3 of CC2, and is transmitted in subframe 4 of CC2, the delay is 0.25 ms;
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;If the uplink data arrives in subframe 4 of CC2, and is transmitted in subframe 5 of CC2, the delay is 0.25 ms;
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;If the uplink data arrives in subframe 5 of CC2 and is transmitted in subframe 6 of CC2, the delay is 0.25 ms;
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;
If the uplink data arrives in subframe 6 of CC2, and is transmitted in subframe 7 of CC2, the delay is 0.25 ms;
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;If the uplink data arrives in subframe 7 of CC2, and is transmitted in subframe 4 of CC1, the delay is 0.25 ms;
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;If the uplink data arrives in subframe 8 of CC2, and is transmitted in subframe 5 of CC1, the delay is 0.25 ms;
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;If the uplink data arrives in subframe 9 of CC2, and is transmitted in subframe 6 of CC1, the delay is 0.25 ms;
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。Therefore, the frame alignment delay of the uplink of the carrier aggregation is the average of the delay of the uplink data transmission, that is, 0.55 ms, and the total delay of the uplink is: the processing delay of the base station side is 0.2 ms + the frame alignment delay is 0.55 ms+ The processing delay on the user side is 0.2 ms + the duration of one TTI is 0.5 ms = 1.45 ms.
