具体实施方式
下文中将结合附图对本申请的实施例进行说明。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在一些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
为了说明本申请的内容，首先对本申请实施例中涉及到名词、工作过程进行解释说明。
本申请的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LIE-A(Advanced long term evolution，先进的长期演进)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、以及第五代移动通信(5th generation mobile networks，5G)系统等，本申请实施例并不限定。
本申请实施例可以用于不同的制式的无线网络。无线接入网络在不同的系统中可包括不同的通信节点。图2为本申请提供的一种无线网络系统的结构示意图。如图2所示，该无线网络系统100包括基站101、用户设备110、用户设备120和用户设备130。基站101分别与用户设备110、用户设备120和用户设备130之间进行无线通信。
本申请实施例中，基站可以是能和用户设备通信的设备。基站可以是任意一种具有无线收发功能的设备。包括但不限于：基站NodeB、演进型基站eNodeB、5G通信系统中的基站、未来通信系统中的基站、WiFi系统中的接入节点、无线中继节点、无线回传节点等。基站还可以是云无线接入网络(cloud radioaccess network，CRAN)场景下的无线控制器；基站还可以是小站，传输节点(transmission reference point，TRP)等，本申请实施例并不限定。
用户设备是一种具有无线收发功能的设备可以部署在陆地上，包括室内或室外、手持、穿戴或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述用户设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端、增强现实(Augmented Reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。用户设备有时也可以称为终端、接入终端、UE单元、UE站、移动站、移动台、远方站、远程终端、移动设备、UE终端、无线通信设备、UE代理或UE装置等。本申请实施例并不限定。
作为举例，本申请的实施例包括1个UE和至少两个TRP(或者一个TRP中包括两个面板)。重复的PDCCH或者PDSCH来自于两个不同的TRP，它们可以在不同的CC或BWP上，也可以在相同的CC或BWP上。
在一个示例性实施方式中，图1为本申请提供的一种信息增强方法的流程示意图。该方法可以适用于Multi-TRP/Pannel场景下PDCCH重复传输的情况。该方法可以由本申请提供的信息增强装置执行，该信息增强装置可以由软件和/或硬件实现，并集成在用户设备(user equipment，UE)上。
如图1所示，本申请实施例提供的信息增强方法主要包括步骤S110和S120。
S110、确定下行控制信息DCI集合中的第一DCI子集和第二DCI子集，其中，所述第一DCI子集包括N个重复DCI，所述第二DCI子集包括M-N个非重复DCI；N为大于1的整数，M为大于N的整数。
DCI是指PDCCH中携带的信息。不同类型的DCI所包含的域及域中内容可能不一样。
例如：下行分配指示(Downlink assignment index，DAI)用于指示在混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)的反馈时间窗口内有多个子帧包含下行传输，防止一些DCI丢失时，UE可能错误地反馈确认消息(Acknowledgement，ACK)，在NR协议中仅DCI格式(format)0_1和1_1中存在DAI域。
又如：冗余版本(Redundancy version，RV)表示从缓冲区取数据的起始位置，不同的RV版本数据可以增量合并，提高解码正确率，NR协议中仅DCI format0_1、0_0、1_0和1_1中存在RV域。
再如：DCI format 0_0中时域资源分配(Time domain resource assignment，TDRA)域中4比特(bit)用来索引调度的PUSCH相对DCI的时隙偏移K2、时隙内符号起始位置S和时隙内符号长度L；DCI format 1_0中TDRA域中4bit用来索引调度的PDSCH相对DCI的时隙偏移K0、时隙内符号起始位置S和时隙内符号长度L。
PDCCH可以向UE发送下行调度信息，指示UE接收PDSCH；也可以向UE发送上行调度信息，指示UE发送物理层上行共享信道(Physical Uplink Shared Channel，PUSCH)；还可以发送物理层上行控制信道(Physical Uplink Control Channel，PUCCH)、PUSCH和探测参考信号(Sounding reference signal，SRS)的功控命令；还可以通知UE的时隙格式等。
控制信道资源集合(Control Resource Set，CORESET)由一个或多个控制信道元素(Control Chanel Element，CCE)组成，表示基站可能发送PDCCH的时频资源位置。但UE并不知道PDCCH携带哪种形式的DCI，也不知道该DCI在哪个候选CCE上传输，UE需要对在不同聚合等级CCE上对所有可能的DCI格式盲解。为了减少盲解次数，引入搜索空间(Search Space，SS)的概念，SS是由给定聚合等级的CCE集合组成。基站可以给UE配置一个或多个SS。时域机会occasion由SS中监测周期及偏移monitoringSlotPeriodicityAndOffset决定，表示基站可能发送PDCCH的时域位置，载波单元(Componet Carrier，CC)代表子载波，表示频域位置。
UE根据基站配置信息知道自己的SS，首先尝试使用相应的无线网络临时标识(Radio Network Temporary Identifier，RNTI)、可能的DCI format、可能的聚合等级对自己SS内的CCE做循环冗余校验(Cyclic Redundancy Check，CRC)，如果校验成功，UE知道该信息是自己需要的，从而解出DCI中的内容。
UE按照先时域后频域的顺序在相应的搜索空间(Search Space，SS)上依次盲检DCI，得到下行分配指示(Downlink assignment index，DAI)，由于重复的DCI内容中有相同的DAI值，这样盲解后DAI取值违反了既定规则，UE就可能理解错误，以为发生了漏检。即UE在盲解DCI时，不能保证正确解调所有的DCI，需要考虑重复的DCI的检测情况及如何解决遇到DAI不对齐问题。
所述DCI集合包括M个DCI，其中，M个DCI包括N个重复DCI和M-N个非重复DCI；第一DCI子集包含N个重复DCI，其中，M为大于N的整数。在一个示例性实施方式中，所述方法还包括：接收所述预先配置的N个重复DCI的关联关系，所述关联关系用于确定重复DCI。
所述配置的N个重复DCI的关联关系包括以下至少之一：
每个重复DCI在搜索空间SS上增加搜索空间参考(Search Space Reference，SSREF)域，其中，所述SSREF域中内容非当前DCI所在搜索空间标识(Search Space Identifier，SSID)。
每个重复DCI在控制信道资源集合CORESET上增加控制信道资源集合参考(Control Resource Set Reference，CORESETREF)域，其中，CORESETREF域中内容非当前DCI所在控制信道资源集合标识(Control Resource Set Identifier，CORESETID)。
预定义的高层重复信令规则，其中，所述重复信令规则，包括以下至少之一：SS上配置有相同的第一信息元素，其中，所述第一信息元素包括以下至少之一：第一持续时间、监测时隙周期、监测时隙周期偏移、候选PDCCH个数、DCI格式、监测时隙内的符号位置；CORESET上配置有相同的第二信息元素，其中，所述第二信息元素包括以下至少之一：第二持续时间、控制信道元素到资源元素组映射类型、频域资源、交织大小、PDCCH DMRS的加扰ID、预编码粒度、传输控制信息集合、移位目录、资源组绑定个数。
在一个示例性实施方式中，基站给UE配置M个CORESET或者SS，并且指示给UE，M个CORESET或者SS中存在N个CORESET或SS上的DCI是重复的，其中，M、N为正整数且M>N>1，如M＝4，N＝2。
在本实施例中可以通过如下方式中的任意一种或者多种的组合来给重复的DCI配置参考信息。
第一种方式，基站只给2个重复DCI所在的SS配置参考信息，另外2个非重复DCI所在的SS不配置参考信息。
如果第一SS和第二SS上的DCI是重复的，且第一SS对应的ID为SSID1，第二SS对应的ID为SSID2，那么在第一SS增加一个SSREF域，SSREF域中 的内容为SSID2，在第二SS增加一个SSREF域，SSREF域中的内容为SSID1。
第二种方式，基站只给2个重复DCI所在的CORESET配置参考信息，另外2个非重复DCI所在的CORESET不配置参考信息。
如果第一CORESET和第二CORESET上的DCI是重复的，且第一CORESET对应的ID为CORESETID1，第二CORESET对应的ID为CORESETID2，那么在第一CORESET增加一个CORESETREF域，CORESETREF域中的内容为CORESETID2，在第二CORESET增加一个CORESETREF域，CORESETREF域中的内容为CORESETID1。
第三种方式，基站配置重复信令规则。
配置重复信令规则包括以下至少之一：给2个的重复的DCI，在SS上配置相同的一个或多个第一信息元素；给不重复的2个DCI，在SS上，配置不同的一个或多个第一信息元素。给2个的重复的DCI，在CORESET上配置相同的一个或多个第二信息元素；给不重复的2个DCI，在CORESET上，配置不同的一个或多个第二信息元素。
第一信息元素可以是以下至少之一：第一持续时间、监测时隙周期、监测时隙周期偏移、候选PDCCH个数、DCI格式、监测时隙内的符号位置等。其中，第二信息元素可以是以下至少之一：第二持续时间、控制信道元素到资源元素组映射类型、频域资源、交织大小、PDCCH DMRS的加扰ID、预编码粒度、传输控制信息集合、移位目录或资源组绑定个数。
例如：搜索空间SS上配置有相同的第一持续时间、相同的监测时隙周期、相同的监测时隙周期偏移、相同的候选PDCCH个数、相同的DCI格式和相同的监测时隙内的符号位置。
例如：控制信道资源集合CORESET上配置有相同的配置第二持续时间、相同的控制信道元素到资源元素组映射类型、相同频域资源、相同交织大小、相同的PDCCH DMRS的加扰ID、相同的预编码粒度、相同的传输控制信息集合、相同的移位目录或相同的资源组绑定个数。
UE按照基站配置M个CORESET或者SS的信息，及指示重复DCI的规则，确定盲解DCI的时频资源位置，需要盲解DCI的个数，重复DCI的时频资源位置。
在一个示例性实施方式中，确定DCI集合中N个重复DCI，包括以下至少方式之一：将DCI集合中满足高层重复信令规则的N个DCI确定为重复DCI；将DCI集合中在搜索空间SS上有搜索空间参考SSREF域的N个DCI确定为重复DCI；将DCI集合中在控制信道资源集合CORESET上有信道控制信道资源 集合参考CORESETREF域的N个DCI确定为重复DCI；其中，所述N个DCI包括的所有域的内容相同。
在一个示例性实施方式中，确定DCI集合中N个重复DCI可以是UE检测到第一SS和第二SS都存在一个SSREF域，SSREF域中的内容分别为SSID2和SSID1，SSID1对于第一SS，SSID2对应第二SS，则确定第一SS和第二SS上的DCI是重复DCI。
在一个示例性实施方式中，确定DCI集合中N个重复DCI还可以是UE检测到第一CORESET和第二CORESET都存在一个CORESETREF域，CORESETREF域中的内容分别为CORESETID2和CORESETID1，CORESETID1对应第一CORESET，CORESETID2对应第二CORESET，则确定第一CORESET和第二CORESET上的DCI是重复DCI。
在一个示例性实施方式中，确定DCI集合中N个重复DCI还可以是在SS上检测到至少一个或多个相同的第一信息元素，则确定SS上的DCI为重复DCI。第一信息元素可以为以下至少之一：第一持续时间、监测时隙周期、监测时隙周期偏移、候选PDCCH个数、DCI格式、监测时隙内的符号位置等。
在一个示例性实施方式中，确定DCI集合中N个重复DCI还可以是在CORESET上检测到至少一个或多个相同的第二信息元素，则确定CORESET上的DCI为重复DCI。第二信息元素可以为以下至少之一：第二持续时间、控制信道元素到资源元素组映射类型、频域资源、交织大小、PDCCH DMRS的加扰ID、预编码粒度、传输控制信息集合、移位目录、资源组绑定个数等。
S120、根据所述重复DCI确定DCI集合中DCI的相关信息。
在一个示例性实施方式中，所述根据所述重复DCI确定DCI集合中DCI的相关信息，包括下述方式之一：
根据所述重复DCI确定所述DCI集合下行分配指示DAI的取值；根据所述重复DCI确定所述重复DCI调度资源的传输时隙；根据所述重复DCI确定所述重复DCI冗余版本RV；根据所述重复DCI确定所述DCI集合DAI的取值和所述重复DCI调度资源的传输时隙；根据所述重复DCI确定所述DCI集合下行分配指示DAI的取值和所述重复DCI冗余版本RV。
所述DCI集合包括M个DCI，其中，M个DCI包括N个重复DCI和M-N个非重复DCI；第一DCI子集包含N个重复DCI，其中，M为正整数且M>N。
在一个示例性实施方式中，根据所述重复DCI确定所述DCI集合下行分配指示DAI的取值。
在一个示例性实施方式中，所述根据所述重复DCI确定所述DCI集合中下 行分配指示DAI的取值，包括：根据第一DCI子集中N个重复DCI的检测结果，确定所述DCI集合DAI取值，其中，所述第一DCI子集中重复DCI的DAI值相同。
在本实施例中，UE根据基站的参考信息可以确定哪些位置的DCI是重复的，图3为本申请提供的重复DCI均被检测到的DAI取值的示意图，如图3所示，UE依次在(occasion 0，CC0)、(occasion 0，CC1)、(occasion 0，CC2)、(occasion 1，CC0)、(occasion 1，CC1)的位置上盲解DCI，并且知道(occasion 0，CC0)、(occasion 1，CC0)上的DCI是重复的，即图中虚框位置的1的DCI与实框位置的1的DCI是重复的。但UE在盲解DCI时，并不能保证正确解调所有的DCI，需要考虑重复的DCI的检测情况及如何解决遇到DAI不对齐问题。
图4是本申请提供的DAI计算的示意图，如图4所示，DAI值的计算是按照先时域后频域的顺序累加后结果模4加1。
在一个示例性实施方式中，如果未检测到第一DCI子集中任一个重复DCI，则根据实际检测到DCI的顺序确定DCI集合DAI的取值。图5是本申请提供的重复DCI均未被检测到的DAI取值的示意图。如图5所示，重复DCI都没有检测到，即图5中实框和虚框位置的1都没有检测到，UE会按照实际检测到DCI顺序来计算DAI值，并不会按照DCI中DAI值预留，即最终的DAI取值为123，而不是234。
在一个示例性实施方式中，如果检测到第一DCI子集中至少一个重复DCI，则将第一DCI子集中时域机会索引和载波单元索引均最小的DCI作为目标DCI，将第一DCI子集中DAI放到目标DCI位置，并根据目标DCI的DAI和DCI集合中非重复DCI的DAI确定所述DCI集合的DAI取值，其中，DAI的位置由时域机会索引和载波单元索引共同确定。
第一DCI子集中非目标DCI位置的DAI值忽略，DCI集合中非重复DCI的DAI之间的相对顺序保持不变，DCI集合中非重复DCI的DAI与目标DCI的DAI之间的相对顺序保持不变，其中，DCI集合中非重复DCI的DAI值根据检测DCI中DAI域的内容确定。
图3是本申请的重复DCI均被检测到的DAI取值的示意图。如图3所示，两个DCI的都检测到，实框和虚框位置的1都检测到。UE根据检测结果及基站配置情况确定实框和虚框位置的1所在位置的DCI是重复的，盲解后的DAI取值是12314，此时UE已经知道第一个实框1与第二个虚框1是重复的，重复的DCI中目标DCI位于第一个实框1的位置，最终的DAI取值是1234。
图6是本申请提供的仅靠前重复DCI被检测到的DAI取值的示意图。只有最前面的重复DCI被检测到，即图6中实框1被检测到，虚框1没有被检测到。重复的DCI中目标DCI位于第一个实框1的位置，UE盲解后DAI取值是1234，DAI取值正常。
图7是本申请提供的仅靠后重复DCI被检测到的DAI取值的示意图。只有最后面的重复DCI检测到，即图7中实框1没有被检测到，虚框1被检测到。UE盲解后DAI取值是2341，UE知道实框1的DCI与虚框1的DCI是重复，虽然实框1位置的DCI没有检测到，但重复的DCI中目标DCI位于第一个实框1的位置，最终的DAI取值是1234。
图8是本申请提供的至少一个重复DCI被检测到的最终DCI序列示意图。上述三种至少一个重复DCI被检测到的情况，需要将重复的DCI的最终DAI值放在重复DCI中时域机会索引和载波单元索引都最小的的DCI位置，对应图8中实框1的位置，按照或运算得到最终DCI取值为1234。
在一个示例性实施方式中，根据所述重复DCI确定所述重复DCI调度资源的传输时隙。
