Description

通信系统的载波聚合方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种通信系统的载波聚合方法及装置。
背景技术
长期演进(Long Term Evolution，简称为LTE)系统中的无线帧(Radio Frame)包括频分双工(Frequency Division Duplex，简称为FDD)模式和时分双工(Time Division Duplex，简称为TDD)模式的帧结构。如图1所示，在FDD模式的帧结构中，一个10毫秒(ms)的无线帧由二十个长度为0.5ms、编号为0～19的时隙(slot)组成，时隙2i和2i+1组成长度为1ms的子帧(subframe)i(其中，0≤i≤9)。如图2所示，在TDD模式的帧结构中，一个10ms的无线帧由两个长为5ms的半帧(half frame)组成，一个半帧中包括5个长度为1ms的子帧，子帧i定义为2个长为0.5ms的时隙2i和2i+1的组合(其中，0≤i≤9)。各子帧支持的上下行配置如表1所示。其中，“D”表示专用于下行传输的子帧，“U”表示专用于上行传输的子帧，“S”表示用于下行导频时隙(Downlink Pilot Time Slot，简称为DwPTS)、保护间隔(Guard Period，简称为GP)和上行导频时隙(Uplink Pilot Time Slot，简称为UpPTS)这三个域的特殊子帧。
表1各子帧支持的上下行配置示意表
Figure PCTCN2014088425-appb-000001
从上表可以看出，LTE TDD支持5ms和10ms的上下行切换周期。如果下行到上行转换点周期为5ms，特殊子帧会存在于两个半帧中；如果下行到上行转换点周期为10ms，特殊子帧只存在于第一个半帧中；子帧#0和子帧#5以及DwPTS总是用于下行传输；UpPTS和紧跟于特殊子帧后的子帧专用于上行传输。
LTE FDD系统中，对下行混合自动重传请求(Hybrid Automatic Repeat Request，简称为HARQ)中发送物理下行共享信道(Physical Downlink Shared Channel，简称为 PDSCH)与相应的混合自动重传请求-确认(HARQ-ACK)信息有如下定时规定，即对于下行HARQ定时关系有如下规定：当UE在子帧n-4上检测到PDSCH传输或者指示下行SPS release的物理下行控制信道(Physical Downlink Control Channel，简称为PDCCH)，UE将在上行子帧n上传输对应的HARQ-ACK信息，也就是下行HARQ的反馈时延为4；对于LTE TDD系统中，对下行HARQ定时关系有如下规定：当UE在子帧n-k上检测到PDSCH传输或者指示下行半持续调度SPS释放的PDCCH，UE将在上行子帧n上传输对应的HARQ-ACK信息，其中k属于K，K为{k0,k1,...,kM-1}，M为K的总数，M最大值为4，k对应的值就是下行HARQ的反馈时延，不同上下行配置中K的取值如表2所示。从表2可以得到，TDD系统的下行HARQ反馈时延大于等于LTE FDD系统的下行HARQ反馈时延4，
表2TDD系统中下行相关组索引K：{k0,k1,...,kM-1}

为了满足高级国际电信联盟(International Telecommunication Union-Advanced，简称为ITU-Advanced)的要求，作为LTE的演进标准的高级长期演进(Long Term Evolution Advanced，简称为LTE-A)系统需要支持更大的系统带宽(最高可达100MHz)，并需要后向兼容LTE现有的标准。在现有的LTE系统的基础上，可以将LTE系统的带宽进行合并来获得更大的带宽，这种技术称为载波聚合(Carrier Aggregation，简称为CA)技术，该技术能够提高IMT-Advance系统的频谱利用率、缓解频谱资源紧缺，进而优化频谱资源的利用。
在引入了载波聚合的系统中，进行聚合的载波称为分量载波(Component Carrier，简称为CC)，也称为一个服务小区(Serving Cell)。同时，还提出了主分量载波/小区(Primary Component Carrier/Cell，简称为PCC/PCell)和辅分量载波/小区(Secondary Component Carrier/Cell，简称为SCC/SCell)的概念，在进行了载波聚合的系统中，至 少包含一个主服务小区和辅服务小区，其中主服务小区一直处于激活状态。现有载波聚合技术中，支持FDD服务小区聚合，其对应的下行HARQ反馈时延为4。支持相同上下行配置的TDD服务小区聚合，也支持不同上下行配置的TDD服务小区聚合。对于TDD服务小区聚合，其对应的下行HARQ反馈时延为k，k值如表2所示。从反馈时延来看，现有的载波聚合TDD系统的反馈时延大于等于载波聚合的FDD系统。
针对相关技术中载波聚合TDD系统的反馈时延大于等于载波聚合的FDD系统的问题，目前尚未提出有效的解决方案。

下面对本发明实施例的具体实例进行描述。
实施例一
实例一
在本实例中，主服务小区为TDD服务小区且上下行配置为#0，辅服务小区#0为TDD服务小区且上下行配置为#1，辅服务小区#1为TDD服务小区且上下行配置为#1；
作为本发明实施例的一个例子，一种载波聚合的方法是：主服务小区为固定服务小区，那么辅服务小区#0、辅服务小区#1和主服务小区以子帧偏差N0，N1聚合，如图5所示；其中，主服务小区的上下行配置为#0，辅服务小区#0和辅服务小区#1的上下行配置都为#1，所以N0，N1的值都为3，或者，主服务小区的上下行配置为#0，所以N0，N1的值都为3，或者，基站和终端预先约定好N0，N1的值为3。
实例二
在本实例中，如图6所示：主服务小区为TDD服务小区且的上下行配置为0，辅服务小区#0为TDD服务小区且上下行配置为#1，辅服务小区#1为TDD服务小区且上下行配置为#0；
作为本发明实施例的一个例子，一种载波聚合的方法是：主服务小区为固定服务小区，辅服务小区#0、辅服务小区#1和主服务小区以子帧偏差N0，N1聚合，如图6所示；其中，主服务小区的上下行配置为#0，辅服务小区#0的上下行配置都为#1，所以N0，值为3，主服务小区的上下行配置为#0，辅服务小区#1的上下行配置都为#0，所以N1，值为2。
实例三
在本实例中，主服务小区为FDD服务小区，辅服务小区#0为FDD服务小区。
作为本发明实施例的一个例子，一种载波聚合的方法是：终端和基站预先约定好主服务小区为固定服务小区，辅服务小区#0合主服务小区以子帧偏差N0聚合，其中，基站和终端预先约定好N0的值为5，图7以FDD下行所示。从图中可以看出，由于聚合的服务小区的公有信息在不同的子帧发送，从而可以降低公有信息小区间干扰。
实例四
在本实例中，服务小区#0为TDD服务小区且上下行配置为0，服务小区#1为TDD服务小区且上下行配置为#1，服务小区#2为TDD服务小区且上下行配置为2，服务小区#3为TDD服务小区且上下行配置为#3；
作为本发明实施例的一个例子，一种载波聚合的方法是：小区索引相邻的服务小区之间存在子帧偏差，即服务小区#0和服务小区#1之间存在子帧偏差N0，服务小区#1和服务小区#2之间存在子帧偏差N1聚合，服务小区#2和服务小区#3之间存在子帧偏差N2，假设N0和N2的取值相同为2，N1的取值为1，如图8所示。
实施例二
实例一：
在本实例中，如图9所示，主服务小区的上下行配置为#0，辅服务小区的上下行配置为#1，主服务小区和辅服务小区按照本发明给出的载波聚合方法进行聚合。
终端通过高层信令获得主服务小区和辅服务小区之间的子帧偏差N0＝3，其中高层信令可以是RRC信令，用2bit表示子帧偏差为1、2、3、4，也可以是MAC层信令。
终端在无线帧#m的子帧#0上检测到主服务小区有PDSCH传输，因为主服务小区对应无线帧#m子帧#4，所以主服务小区子帧#0上PDSCH对应的HARQ-ACK响应在主服务小区无线帧#m子帧#4上发送，即k＝4；终端在无线帧#m的子帧#1上检测到主服务小区有PDSCH传输，因为辅服务小区对应无线帧#m子帧#5为上行子帧，所以主服务小区子帧#1上PDSCH对应的HARQ-ACK响应在辅服务小区无线帧#m子帧#5上发送，即k＝4；终端在无线帧#m的子帧#5上检测到主服务小区有PDSCH传输，因为主服务小区对应无线帧#m子帧#9，所以主服务小区子帧#5上PDSCH对应的HARQ-ACK响应在主服务小区无线帧#m子帧#9上发送，即k＝4；终端在无线帧#m的子帧#6上检测到主服务小区有PDSCH传输，因为辅服务小区对应无线帧#m+1子帧#0为上行子帧，所以主服务小区子帧#6上PDSCH对应的HARQ-ACK响应在辅服务小区无线帧#m+1子帧#0上发送，即k＝4。
终端在无线帧#m的子帧#2上检测到辅服务小区有PDSCH传输，因为辅服务小区对应无线帧#m子帧#6为上行子帧，所以辅服务小区子帧#2上PDSCH对应的HARQ-ACK响应在辅服务小区无线帧#m子帧#6上发送，即k＝4；终端在无线帧#m的子帧#3上检测到辅服务小区有PDSCH传输，因为主服务小区对应无线帧#m子帧#7为上行子帧，所以辅服务小区子帧#3上PDSCH对应的HARQ-ACK响应在主服务小区无线帧#m子帧#7上发送，即k＝4；终端在无线帧#m的子帧#4上检测到辅服务小区有PDSCH传输，因为主服务小区对应无线帧#m子帧#8为上行子帧，所以辅服务小区子帧#4上PDSCH对应的HARQ-ACK响应在主服务小区无线帧#m子帧#8上发送，即k＝4；终端在无线帧#m的子帧#7上检测到辅服务小区有PDSCH传输，因为辅服务小区对应无线帧#m+1子帧#0为上行子帧，所以辅服务小区子帧#7上PDSCH对应的 HARQ-ACK响应在辅服务小区无线帧#m+1子帧#0上发送，即k＝4；终端在无线帧#m的子帧#8上检测到辅服务小区有PDSCH传输，因为主服务小区对应无线帧#m+1子帧#1为上行子帧，所以辅服务小区子帧#8上PDSCH对应的HARQ-ACK响应在主服务小区无线帧#m+1子帧#1上发送，即k＝4；终端在无线帧#m的子帧#9上检测到辅服务小区有PDSCH传输，因为主服务小区对应无线帧#m+1子帧#2为上行子帧，所以辅服务小区子帧#9上PDSCH对应的HARQ-ACK响应在主服务小区无线帧#m+1子帧#2上发送，即k＝4。
当没有配置跨载波调度时，终端在主服务小区无线帧#m下行子帧#0上检测到PUSCH传输对应的DCI，在主服务小区子帧4上传输对应的PUSCH，如果该DCI中CSI触发域设置为触发上报，那么对应的CSI在主服务小区子帧4上发送；终端在辅服务小区无线帧#m子帧#8上检测该PUSCH对应的PHICH，如果PHICH为NACK，终端在主服务小区无线帧#m+1子帧#2上发送重传PUSCH。当没有配置跨载波调度时，终端在主服务小区无线帧#m下行子帧#1上检测到PUSCH传输对应的DCI，在辅服务小区无线帧#m子帧#5上传输对应的PUSCH，如果该DCI中CSI触发域设置为触发上报，那么对应的CSI在辅服务小区无线帧#m子帧#5上发送；终端在辅服务小区无线帧#m子帧#9上检测该PUSCH对应的PHICH，如果PHICH为NACK，终端在主服务小区无线帧#m+1子帧#3上发送重传PUSCH。
从上面的实施例可以看出，通过本发明提供的载波聚合方式，即通过对聚合的服务小区配置子帧偏差，可以使得每个无线帧上都有对应的上行子帧和下行子帧，从而使得HARQ-ACK响应对应的反馈延迟都为4，PDCCH和PUSCH之间的调度定时为4，PUSCH和对应的PHICH反馈之间的定时为4，PHICH和重传PUSCH之间的定时为4，为现有TDD系统反馈延迟的最小值。
实例二
在本实例中，如图10所示，主服务小区的上下行配置为#1，辅服务小区的上下行配置为#0，主服务小区和辅服务小区按照本发明给出的载波聚合方法进行聚合。
终端检测辅服务小区的同步信道的位置，确定子帧#2为辅服务小区对应的第一个子帧，即子帧偏差N0＝2；终端在所述主服务小区和辅服务小区上收发信息的过程和实例一类似，这里不再赘述。
实例三
在本实例中，如图11所示，主服务小区的上下行配置为#2，辅服务小区的上下行配置为#0，主服务小区和辅服务小区按照本发明给出的载波聚合方法进行聚合。
终端通过物理层信令获得主服务小区和辅服务小区之间的子帧偏差N0＝2，其中物理层信令可以是DCI中空闲比特，或是DCI中增加2比特来表示1～4个子帧偏差等。
终端在无线帧#m的子帧#0上检测到主服务小区有PDSCH传输，因为主服务小区和辅服务小区对应无线帧#m子帧#8都为下行子帧，所以主服务小区和辅服务小区上PDSCH对应的HARQ-ACK都在主服务小区上发送，此时k值由现有技术确定，例如，可以将辅服务小区看做是FDD服务小区，其中辅服务小区对应上行子帧相当于FDD服务小区中没有调度的子帧，k的取值可以根据TDD-FDD聚合中规定的取值确定。

因为主服务小区和辅服务小区对应无线帧#m子帧#8，#9都为下行子帧，所以主服务小区和辅服务小区上PDSCH对应的HARQ-ACK都在主服务小区上发送，此时k值可以根据相关技术确定，在此不再赘述。
