Description

下行控制信息DCI的配置、下行数据的接收方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种下行控制信息DCI的配置、下行数据的接收方法及装置。
背景技术
为了满足高级国际电信联盟(International Telecommunication Union-Advanced，简称为ITU-Advanced)的要求，作为长期演进(Long-Term Evolution，简称为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，该技术能够提高高级国际无线通信系统(International Mobile Telecommunication Advance，简称为IMT-Advance)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，现有载波聚合支持最多5个分量载波的聚合。
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。LTE-A系统中引入跨载波调度即某服务小区上的物理下行控制信道(Physical Downlink Control Channel，简称为PDCCH)可以调度多个服务小区的物理下行共享信道(Physical Downlink Shared Channel，简称为HS-PDSCH)/终端发射上行数据信道(Physical uplink shared channel，简称为PUSCH)，其中PDCCH所在的服务小区称为调度小区，PDSCH/PUSCH所在的服务小区称为被调度服务小区。当配置跨载波调度时，终端在服务小区c上检测到含有载波指示域(Carrier indicator field，简称CIF)，那么用户设备(User Equipment，简称为UE)根据CIF的值去在对应的服务小区上解PDSCH。
在后续版本中，考虑支持至多32个服务小区的聚合。对于至多32个服务小区的聚合，需要考虑如何配置32个服务小区的下行控制信息才能使得终端正确的获得各个服务小区的下行控制信息，从而正确的解得下行数据。
针对相关技术中，在支持至多32个服务小区的聚合的情况下，终端无法正确的获得各个服务小区的下行控制信息的问题，还未提出有效的解决方案。

步骤S104，向终端发送与该服务小区对应的该DCI。
通过上述步骤，利用上述方式1或者方式2对聚合的服务小区配置对应的DCI，解决了相关技术中在支持至多32个服务小区的聚合的情况下，终端无法正确的获得各个服务小区的下行控制信息的问题，实现了终端正确的获得支持至多32个聚合的服务小区的下行控制信息，从而正确的解得下行数据的效果。
上述步骤S102中涉及到为聚合的服务小区配置对应的DCI，在另一个可选实施例中，至多支持所述T个载波的聚合载波且配置自调度时，采用以下规则至少之一为该服务小区配置对应的DCI：规则1：DCI对应的CRC长度大于L，其中L为16；规则2：DCI中包括校验域，其中校验域对应的大小为F比特。从而更优的为聚合的服务小区配置对应的DCI。
在该CIF为X比特的情况下，即，采用上述方式2为聚合的服务小区配置对应的DCI时，在一个可选实施例中，通过信令配置该服务小区对应的虚拟载波指示，其中，虚拟载波指示用于指示该服务小区在虚拟载波集中的索引，其中，虚拟载波集根据信令配置得到。从而使得终端可以根据CIF和虚拟载波指示得到包含该CIF的DCI和对应的PDSCH之间的对应关系，上述信令例如为高层信令。

针对相关技术中存在的上述问题，下面结合可选实施例进行说明，在本可选实施例中结合了上述可选实施例及其可选实施方式。
实施例一
现有LTE系统中，物理下行控制信道/增强的物理下行控制信道(PDCCH/ePDCCH)用于承载下行控制信息(DCI)，包括：上行调度信息，下行调度信息和上行功率控制信息。DCI的格式分为以下几种：DCI format0，DCI format1，DCI format1A，DCI format1B，DCI format1C，DCI format1D，DCI format2，DCI format2A，DCI format2B，DCI format2C，DCI format2D，DCI format3，DCI format3A和DCI format4，其中：DCI format0/4用于指示物理上行共享信道(PUSCH)上上行数据的调度，DCI format1，DCI format1A，DCI format1B，DCI format1C，DCI format1D，DCI format2，DCI format2A，DCI format2B，DCI format2C，DCI format2D用于指示物理下行共享信道(PDSCH)上下行数据的调度，DCI format3和DCI format3A用于物理上行控制信道和PUSCH的功率控制信令的不同模式。
PDCCH传输的物理资源以控制信道元素(Control channel element，简称为CCE)为单位，一个CCE的大小为9个资源组(Resource element Group，REG)即36个资源元素(Resource element，RE)。一个PDCCH可能占用1,2,4,8个CCE。针对每个聚合等级定义一个搜索空间，包括公有搜索空间和用户设备专有搜索空间。公有搜索空间承载的是与系统信息块，随即接入响应以及寻呼相关的公有信息；UE专用的搜索空间承载的是UE各自的上下行调度授权信息。UE在接收下行控制信息时，检测聚合等级为4和8的各一公共搜索空间，以及聚合等级为1,2,4,8的各一UE专有搜索空间，公共搜索空间和UE专有搜索空间可以重叠。具体的检测次数和对应的搜索空间如表1所示。
表1检测次数和搜索空间对应关系表
Figure PCTCN2015088303-appb-000001
UE通过高层信令半静态的被设置为以下多种传输模式中的一种，按照用户专有的搜索空间的PDCCH的指示来接收PDSCH数据：
模式1：单天线端口；端口0；
模式2：发射分集；
模式3：开环空间复用；
模式4：闭环空间复用；
模式5：多用户多输入多输出；
模式6：闭环RANK＝1预编码；
模式7：单天线端口；端口5；
模式8：双层传输模式；端口7和8；
模式9：至多8层传输：端口7-14；
模式10：至多8层传输：端口7-14；
如果UE被高层设置为用小区无线网络临时标识(Cell Radio Network Temporary Identifier，简称为Temporary C-RNTI)加扰的循环冗余校验码(Cyclic Redundancy Check，简称为CRC)来进行PDCCH解码，则UE应当按照表2中定义的相应组合来解码PDCCH和相关的PDSCH。

如果UE被高层设置为用小区无线网络临时标识C-RNTI加扰的循环冗余校验来进行PDCCH解码，则UE应当按照表3中定义的相应组合来解码PDCCH和所有相关的PUSCH。
表3上行传输模式，DCI格式、搜索空间和传输方案的对应关系表
Figure PCTCN2015088303-appb-000005
为了解决PDCCH容量问题，后续版本还引入了增强的PDCCH(enhanced PDCCH，简称为ePDCCH)，ePDCCH不同于PDCCH之处在于ePDCCH通过频率复用的方式与PDSCH复用，ePDCCH在频域上的映射方式有连续映射和离散映射，基站会配置k个资源块对集合用作传输ePDCCH，1个资源块对集合包括N个资源块对，其中，k大于等于1，N的值为1,2,4,8,16，1个资源块对包括16个增强的资源单元组(ennhanced Resource Element Group，简称eREG)，1个资源块可以划分为2个eCCE或者4个eCCE，连续映射的ePDCCH对应的L-eCCe由1个资源对内的eREG构成，离散映射的ePDCCH对应的D-eCCE由多个资源块对的eREG构成。
LTE-A系统相对于LTE系统最为显著的特征是，LTE-A系统引入载波聚合技术，也就是将LTE系统的带宽进行聚合以获得更大的带宽。在引入载波聚合的系统中，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，并且规定PUCCH仅在Pcell上传输。
载波聚合中，高层信令指示服务小区是自调度还是跨载波调度，如果是自调度，指示是否含有CIF域，如果是跨载波调度的，指示调度信息所在的小区索引。图18是关于本发明实施例一的示意图，如图18所示，假设有5个下行服务小区聚合，服务小区1的下行控制信息上配置CIF域，高层信令指示{服务小区2，服务小区3，服务小区4}对应的调度信息在服务小区1上，即服务小区1上CIF为000的DCI为服务小区1上PDSCH对应的下行控制信息，服务小区1上CIF为001的DCI为服务小区2上PDSCH对应的下行控制信息，服务小区1上CIF为010的DCI为服务小区3上PDSCH对应的下行控制信息；服务小区1上CIF为011的DCI为服务小区4上PDSCH对应的下行控制信息；服务小区1上CIF为100的DCI为服务小区5上PDSCH对应的下行控制信息。
实施例二
假设有T＝32个下行服务小区聚合，图19是关于本发明实施例二的示意图，如图19所示，载波指示域直接扩展为N＝cel(log2(32))比特，配置了32个服务小区进行聚合，那么载波指示域为5比特，即N＝5；
服务小区1的下行控制信息上配置CIF域，高层信令指示{服务小区2，服务小区3，服务小区4，…，服务小区32}对应的调度信息在服务小区1上，即服务小区1上CIF为00000的DCI为服务小区1上PDSCH对应的下行控制信息，服务小区1上CIF为00001的DCI为服务小区2上PDSCH对应的下行控制信息，服务小区1上CIF为00010的DCI为服务小区3上PDSCH对应的下行控制信息；服务小区1上CIF为00011的DCI为服务小区4上PDSCH对应的下行控制信息；服务小区1上CIF为00100的DCI为服务小区5上PDSCH对应的下行控制信息，服务小区1上CIF为00101的DCI为服务小区6上PDSCH对应的下行控制信息，服务小区1上CIF为00110的DCI为服务小区7上PDSCH对应的下行控制信息，服务小区1上CIF为00111的DCI为服务小区8上PDSCH对应的下行控制信息，服务小区1上CIF为01000的DCI为服务小区9上PDSCH对应的下行控制信息，服务小区1上CIF为01001的DCI为服务小区10上PDSCH对应的下行控制信息，服务小区1上CIF为01010的DCI为服务小区11上PDSCH对应的下行控制信息，服务小区1上CIF为01011的DCI为服务小区12上PDSCH对应的下行控制信息，服务小区1上CIF为01100的DCI为服务小区13上PDSCH对应的下行控制信息，服务小区1上CIF为01101的DCI为服务小区14上PDSCH对应的下行控制信息，服务小区1上CIF为01110的DCI为服务小区15上PDSCH对应的下行控制信息，服务小区1上CIF为01111的DCI为服务小区16上PDSCH对应的下行控制信息，服务小区1上CIF为10000的DCI为服务小区17上PDSCH对应的下行控制信息，服务小区1上CIF为10001的DCI为服务小区18上PDSCH对应的下行控制信息， 服务小区1上CIF为10010的DCI为服务小区19上PDSCH对应的下行控制信息；服务小区1上CIF为10011的DCI为服务小区20上PDSCH对应的下行控制信息；服务小区1上CIF为10100的DCI为服务小区21上PDSCH对应的下行控制信息，服务小区1上CIF为10101的DCI为服务小区22上PDSCH对应的下行控制信息，服务小区1上CIF为10110的DCI为服务小区23上PDSCH对应的下行控制信息，服务小区1上CIF为10111的DCI为服务小区24上PDSCH对应的下行控制信息，服务小区1上CIF为11000的DCI为服务小区25上PDSCH对应的下行控制信息，服务小区1上CIF为11001的DCI为服务小区26上PDSCH对应的下行控制信息，服务小区1上CIF为11010的DCI为服务小区27上PDSCH对应的下行控制信息，服务小区1上CIF为11011的DCI为服务小区28上PDSCH对应的下行控制信息，服务小区1上CIF为11100的DCI为服务小区29上PDSCH对应的下行控制信息，服务小区1上CIF为11101的DCI为服务小区30上PDSCH对应的下行控制信息，服务小区1上CIF为11110的DCI为服务小区31上PDSCH对应的下行控制信息，服务小区1上CIF为11111的DCI为服务小区32上PDSCH对应的下行控制信息。

步骤二：终端根据CIF和虚拟载波指示得到包含所述CIF的DCI和对应的PDSCH之间的对应关系；
步骤三：终端根据DCI获得对应的PDSCH。
实施例四
假设有16个下行服务小区聚合，图20是关于本发明实施例四的示意图，如图20所示，高层信令指示服务小区是自调度还是跨载波调度，如果是自调度，指示是否含有CIF域，如果是跨载波调度的，指示调度信息所在的小区索引和虚拟载波指示。如图所示，根据高层信令中指示调度信息所在的小区索引将聚合的服务小区分成2个虚拟服务小区集，{服务小区3，服务小区5，服务小区7，服务小区8，服务小区9，服务小区10，服务小区11}对应的调度信息在服务小区1上，{服务小区2，服务小区6，服务小区12，服务小区13，服务小区14，服务小区15，服务小区16}对应的调度信息在服务小区4上，也就是{服务小区1，服务小区3，服务小区5，服务小区7，服务小区8，服务小区9，服务小区10，服务小区11}对应一个虚拟载波集，{服务小区2，服务小区4，服务小区6，服务小区12，服务小区13，服务小区14，服务小区15，服务小区16}对 应一个虚拟载波集。
服务小区3对应的虚拟载波指示为001，那么服务小区1上CIF为001的DCI为服务小区3上PDSCH对应的下行控制信息，服务小区5对应的虚拟载波指示为010，那么服务小区1上CIF为010的DCI为服务小区5上PDSCH对应的下行控制信息；服务小区7对应的虚拟载波指示为011，那么服务小区1上CIF为011的DCI为服务小区7上PDSCH对应的下行控制信息；服务小区2对应的虚拟载波指示为001，那么服务小区4上CIF为001的DCI为服务小区2上PDSCH对应的调度信息；服务小区15对应的虚拟载波指示为111，那么服务小区4上CIF为111的DCI为服务小区15上PDSCH对应的调度信息；
通过载波指示域联合虚拟载波指示的方式可以解决至多32个载波聚合中跨载波调度的问题，而且不需要增加现有的CIF域，减少终端检测的复杂度。
实施例五
假设有32个下行服务小区聚合，其中4个服务小区位于授权频谱，即{服务小区1，服务小区2，服务小区3和服务小区4}为授权频谱上的小区，28个服务小区位于非授权频谱，{服务小区5，服务小区6，…，服务小区32}位于非授权频谱，将聚合的下行服务小区分为4组，每组由一个授权频谱上的服务小区和7个非授权频谱上的小区组成，即组1由{服务小区1，服务小区5，服务小区6，服务小区7，服务小区8，服务小区9，服务小区10，服务小区11}组成，组2由{服务小区2，服务小区12，服务小区13，服务小区14，服务小区15，服务小区16，服务小区17，服务小区18}组成，组3由{服务小区3，服务小区19，服务小区20，服务小区21，服务小区22，服务小区23，服务小区24，服务小区25}组成，组4由{服务小区4，服务小区26，服务小区27，服务小区28，服务小区29，服务小区30，服务小区31，服务小区32}组成。配置每组内的服务小区对应的DCI format的大小相同且组内服务小区对应的搜索空间起始位置相同，搜索空间的起始位置根据组索引确定，图17是关于本发明实施例五的示意图，如图21所示，图21给出的连续放置各组的搜索空间，各组的搜索空间也可以以随机，交织等方式放置。
通过分组和配置每个组内DCI format大小相同且每组对应的搜索空间相同，可以减少终端盲检测的次数，节省终端的功耗。
实施例六
假设32个服务小区聚合，其中服务小区1为调度小区，其他服务小区为被调度小区，服务小区1的控制信道为PDCCH和ePDCCH，图22是关于本发明实施例六的示意图，如图22所示，那么{服务小区2，服务小区3，服务小区4，…，服务小区32}对应的搜索空间位于PDCCH和ePDCCH区域，高层信令配置{服务小区2，服务小区3，服务小区4}为一组，{服务小区5，服务小区6，…，服务小区32}为一组，因为{服务 小区2，服务小区3，服务小区4}为一组，所以对应的搜索空间分布于PDCCH区域或者ePDCCH区域，{服务小区5，服务小区6，…，服务小区32}为一组，所以对应的搜索空间分布于ePDCCH区域或者PDCCH区域，图中ePDCCH对应的频域资源是连续的，ePDCCH对应的频域资源也可以是非连续的。
通过扩展搜索空间所在的区域，可以减少调度多个服务小区时的阻塞率，提高PDCCH性能。
实施例七
假设32个服务小区聚合，其中服务小区1为调度小区，其他服务小区为被调度小区，服务小区1的控制信道为ePDCCH，高层信令配置{服务小区2，服务小区3，服务小区4}为一组，{服务小区5，服务小区6，服务小区7}为一组，{服务小区8，服务小区9，…，服务小区32}为一组，因为{服务小区2，服务小区3，服务小区4}为一组，所以对应的搜索空间位于ePDCCH第一资源对集合，{服务小区5，服务小区6，服务小区7}为一组，所以对应的搜索空间位于ePDCCH第二资源对集合，{服务小区8，服务小区9…，服务小区32}为一组，所以对应的搜索空间位于ePDCCH第三资源对集合。
通过扩展搜索空间所在的区域，可以减少调度多个服务小区时的阻塞率，提高PDCCH性能。
实施例八
配置下行控制信息时，实施例五，实施例六和实施例七可以单独配置，也可以联合配置，其中实施例五，实施例六和实施例七对应的分组可以相同，也可以不同。

配置所有激活小区对应的总的最大盲检测次数Mmax；
通过限制总的盲检测次数，减少下行控制信息的虚警概率，提高PDCCH的性能。
具体实施例二
采用时分的方式配置激活的载波。子帧1，激活最多16个服务小区，子帧2，激活最多16个服务小区。
通过限制每个子帧上激活的载波个数，达到降低下行控制信息的虚警概率，提高PDCCH的性能的作用。
实施例十一

根据确定的所有激活服务小区对应的最大盲检测次数Mmax_CC对激活服务小区进行盲检测，根据以下方法之一确定每个激活服务小区对应的最大盲检测次数Mmax_CC，根据得到的各个激活服务小区对应的最大盲检测次数Mmax_CC对各个激活服务小区的PDCCH进行盲检测：
方法1：各个激活服务小区对应的Mmax_CC相当；
方法2：主服务小区和/或授权频谱上的服务小区对应的Mmax_CC和现有最大盲检测次数相同，其他激活服务小区对应的Mmax_CC相当。
具体实施例一
假设激活的载波个数为16个，Mmax为800，采用方法1确定Mmax_CC，即每个激活小区对应的Mmax_CC为(800/16)后向下取整＝50，根据最大盲检测次数50对各个激活服务小区的PDCCH进行盲检测。
具体实施例二
激活的载波个数为16个，Mmax为800，采用方法2确定Mmax_CC，那么主服务小区对应的Mmax_CC为60(和现有最大盲检测次数相同)，剩余15个激活服务小区对应的最大盲检测为((800-60)/15)后向下取整＝49，根据最大盲检测次数50对各个激活服务小区的PDCCH进行盲检测。
具体实施例三
激活的载波个数为16个，处在授权载波上的激活服务小区个数为10个，采用方法2确定Mmax_CC，那么处在授权载波上的10个激活服务小区对应的Mmax_CC为60，剩余6个激活服务小区对应的最大盲检测为((800-60*10)/6)后向下取整＝33，根据最 大盲检测次数50对各个激活服务小区的PDCCH进行盲检测。
通过限制总的盲检测次数达到降低下行控制信息的虚警概率，提高PDCCH的性能的作用。
