技术领域
本公开涉及通信技术领域，特别是指一种盲检能力上报方法、盲检配置、盲检方法、终端及基站。
背景技术
在LTE系统中，终端采用盲检测(blind decode)方式检测基站发送的下行控制信道PDCCH，获得下行控制信息DCI。终端在每个非不连续接收(non-DRX)的下行子帧都需要进行下行控制信道盲检。终端进行下行控制信道PDCCH盲检的检测次数，与如下参数相关：
1)终端同时支持的下行控制信息DCI格式类型，每种DCI格式类型具有不同的DCI大小(DCI size)。以LTE为例，终端需要盲检两种DCI格式类型，如DCI format 1A和DCI format 2。
2)终端需要盲检的PDCCH聚合等级(aggregation level)：在LTE系统中，可能的PDCCH聚合等级包括{1,2,4,8,16,32}，终端基于协议或网络的配置在该集合中选择盲检全部或部分的聚合等级。
3)终端进行盲检的PDCC搜索空间(search space)：LTE系统中搜索空间定义为针对每聚合等级的一系列需要盲检控制信道单元(Control Channel Element，CCE)资源，包括CCE起始位置和候选资源(candidate)数目。
具体的，LTE系统中下行控制信道盲检的说明如下：
在LTE中，因为下行控制信道PDCCH是基站发送的指令，终端UE在此之前除了一些系统信息外没有接收过其他信息，因此UE不知道其占用的CCE数目大小、位置以及传送的DCI格式。因此PDCCH的检测属于盲检测。
首先UE需要确定PDCCH携带的是哪种下行控制信息(Downlink Control  Indicator，DCI)格式：对于DCI格式，UE会根据自己当前的状态期望获得某一种DCI，比如终端在空闲(Idle)状态时期待的信息是寻呼系统信息(paging SI)；终端有上行数据准备发送时期待的是上行调度授权(UL Grant)；终端发起随机接入(Random Access)后期待的是随机接入信道响应(RACH Response)。对于不同信息UE使用相应的无线网络临时标识RNTI去和CCE信息做循环冗余校验(CRC校验)，如果CRC校验成功，那么UE就知道这个信息是自己所需要的，进一步根据调制编码方式解出DCI的内容。
其次，如果UE将所有的CCE遍历一遍，那么对于UE来说计算量将会很大。因此，LTE系统将可用的CCE分为两种搜索空间，分别是公共搜索空间和UE特定搜索空间。公共搜索空间中传输的数据主要是包括系统信息、随机接入响应RAR、寻呼等消息，每个用户都要进行搜索。公共搜索空间的位置是固定的，总是在CCE 0-CCE 16，并且公共搜索空间中聚合等级AL只有4和8两种，因此用户对公共搜索空间进行搜索时，从CCE 0开始按照AL为4搜索4次，再以AL为8搜索2次。UE特定的搜索空间，每个UE的搜索起始点是不同的，且搜索空间的AL分为1，2，4，8四种，其AL为1搜索6次，AL为2搜索6次，AL为4搜索2次，AL为8搜索2次。UE进行盲检测的次数可以计算如下：公共搜索空间搜索次数6次，UE特定搜索空间搜索16次。在UE特定搜索空间UE在同一时刻所处的DCI格式只有两种有效载荷payload大小，因此需要搜索两遍即32次。UE在PDCCH搜索空间进行盲检时，只需对可能出现的DCI进行尝试解码，并不需要对所有的DCI格式进行匹配。
终端盲检就是UE找到CCE的起始位置，在CCE起始位置，截取猜测的DCI长度进行译码，如果译码后的信息比特的CRC和PDCCH中携带的CRC相同，则认为当前的PDCCH承载的信息比特就是当前传输的下行控制信息。各种RNTI隐含在CRC中。
在5G和LTE(长期演进)的设计中，为了使得信道设计更加灵活，引入了终端盲检测的概念。具体来说就是终端在未知控制信令所在的物理资源位置，所占用的资源大小等信息的前提下，通过各种假设进行各种试探性的检测，直到正确解码出信令。在5G系统中，终端的下行控制信道盲检相比 LTE系统更加复杂，表现为：
1)空口(NR)系统引入多个控制信道资源集合(Control Resource Set，CORESET)的概念，CORESET是NR种引入的一类时频资源集合，也就是说终端在所对应的CORESET进行下行控制信道的盲检；且终端可能需要同时在多个CORE SET上进行盲检。
其中，CORESET由一组资源要素组(Resource Element Group，REG)组成。而一个下行控制信道PDCCH由一组CCE组成；一个CCE由一组REG组成。且组成一个下行控制信道PDCCH的最小单元(即控制信道单元CCE)在物理资源的构成上(即REG的构成)可以是集中式的或者是分布式的。
其中，CORESET的时频位置配置可以通过如下的一个或者多个组合来通知：
CORESET的时频位置配置信息可以通过高层信令通知；和/或，CORESET的时频位置配置信息可以通过广播信道、系统信息等通过；和/或，CORESET的时频位置配置信息可以基于如根据系统带宽，子载波间隔，天线配置，载波频率中的一个或者多个信息预先定义。
2)NR系统引入了多种时间上的调度间隔，包括时隙slot和短时隙mini-slot。其中对于一种基带参数numerology配置，一个时隙slot可以包含7个或14个正交频分复用OFDM符号，一个短时隙mini-slot可以包含[1，2，…slot_length-1]个OFDM符号。终端基于网络的配置，可以以时隙slot和/或短时隙mini-slot为时间间隔进行下行控制信道的盲检。
为了支持基于slot或基于mini-slot的调度，基站可以配置终端按照slot或者mini-slot为间隔进行PDCCH监控，以图1为例，终端被网络配置在每个slot第一个OFDM符号进行基于slot的PDCCH监控，同时被网络配置在部分mini-slot进行基于mini-slot的PDCCH监控，如图1所示.
3)NR系统未支持不同的业务类型，例如增强移动带宽eMBB和高可靠通信URLLC，终端需要同时检测的下行控制信息DCI类型潜在的增多。
终端控制信道接收部分的功耗和复杂度与盲检次数密切相关，由于前述的各种原因造成NR系统中PDCCH盲检较LTE系统更加复杂，如果利用现有协议强制所有终端具有相同的盲检能力，将不能适应业务和终端类型多样 化的需求。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
如图2所示，本公开实施例提供一种盲检能力上报方法，应用于终端，该方法包括：
步骤201，确定终端的盲检能力信息；其中，所述终端的盲检能力信息包括：单位时间内终端能够处理的最大盲检次数。
需要说明的是，终端的盲检能力信息具体指终端对下行控制信道PDCCH的盲检能力信息。其盲检能力信息由终端确定，终端可根据不同业务或不同 终端成本的需求来确定不同终端的盲检能力信息。具体的，终端的盲检能力信息定义为单位时间内终端处理的最大盲检次数。
步骤202，将所述终端的盲检能力信息上报给基站。
需要说明的是，终端将上述盲检能力信息上报给基站(或网络)，以辅助基站根据终端的盲检能力信息对终端的盲检行为(该盲检行为具体指对下行控制信道PDCCH的盲检行为)进行合理的盲检配置。
可选的，该盲检能力上报方法具体应用于5G系统，例如NR系统、LTE-A系统等，在此不作具体限定。
进一步的，如图3所示，本公开的上述实施例中，步骤202之后，所述方法还包括：
步骤203，接收所述基站根据所述终端的盲检能力信息为所述终端的盲检行为配置的盲检信息，并根据所述盲检信息进行下行控制信道的盲检。
需要说明的是，终端根据基站配置的盲检信息能够确定基站配置的盲检次数以及在哪个位置对何种类型的上行控制信息进行盲检。通常情况下，基站配置的单位时间内的盲检次数总和小于或者等于终端在单位时间内能够处理的最大盲检次数，但是也存在特殊的情况；例如多个基站同时对终端的盲检行为进行配置，则存在基站配置的单位时间内的盲检次数总和大于终端在单位时间内能够处理的最大盲检次数的情况；再例如，一个基站对终端的盲检行为进行配置时由于其他因素的影响导致其配置的单位时间内的盲检次数总和大于终端在单位时间内能够处理的最大盲检次数；故本公开实施例中不对基站配置的单位时间内的盲检次数总和的大小进行具体限定。
具体的，本公开的上述实施例中，所述单位时间为一个或多个时隙slot；或者，所述单位时间为一个或多个子帧subframe；或者，所述单位时间为一个或多个短时隙mini-slot；或者，所述单位时间为一个预设时间段(该预设时间段可以为一绝对时间单位，例如1ms、2ms等)；或者，所述单位时间为一个或多个传输时间间隔TTI。
具体的，本公开的上述实施例中，所述最大盲检次数为一种或多种盲检类型的盲检次数的总和。
其中，所述盲检类型包括：基于公共搜索空间的下行控制信道的盲检、 以时隙长度为间隔基于用户专用搜索空间的下行控制信道的盲检和/或以短时隙长度为间隔基于用户专用搜索空间的下行控制信道的盲检。
且在每一种盲检类型中，且盲检次数包括：终端在至少一个控制资源集的至少一个候选资源中对至少一种类型的下行控制信息进行解码的次数。
需要说明的是，终端能够在一个或多个控制资源集上进行PDCCH的盲检；和/或，终端能够在一个或者候选资源上进行PDCCH的盲检；和/或，终端能够对一种或多种类型的下行控制信息DCI进行解码。其控制资源集的数量、候选资源的数量、DCI的类型可由基站进行配置。
可选的，本公开的上述实施例中步骤201包括：
分别确定终端在下行控制信道的不同聚合等级上的盲检能力信息；其中，终端在下行控制信道的不同聚合等级上具有相同的盲检能力信息，或者，终端在下行控制信道的不同聚合等级上具有不同的盲检能力信息。
若终端在下行控制信道的不同聚合等级上具有相同的盲检能力信息，即终端的盲检能力与PDCCH的聚合等级不相关，不区分PDCCH的聚合等级大小，不同聚合等级的盲检能力按照同等处理。
若终端在下行控制信道的不同聚合等级上具有不同的盲检能力信息，即终端的盲检能力与PDCCH的聚合等级相关，区分PDCCH的聚合等级大小，盲检能力定义到某一种或多个PDCCH聚合等级上支持的盲检能力；例如，终端对聚合等级为1的PDCCH的盲检能力信息为：单位时间内终端对聚合等级为1的PDDCH的最大盲检次数为100；而终端对聚合等级为2的PDCCH的盲检能力信息为：单位时间内终端对聚合等级为2的PDCCH的最大盲检次数为80。
需要说明的是，当终端的盲检能力与PDCCH的聚合等级相关时，并不限定每个聚合等级均对应不同的聚合能力，可以设定多个聚合等级具有相同的聚合能力，但并不是所有的聚合等级均具有相同的聚合能力。例如，终端对聚合等级为1、2和4的PDCCH的盲检能力相同，设为100；而终端对聚合等级8、16及32的PDCCH的盲检能力相同，设为200；此种情况下也认为终端的盲检能力与PDCCH的聚合等级相关。
进一步的，若终端在下行控制信道的不同聚合等级上具有不同的盲检能 力信息，本公开实施例的步骤202包括：
将终端在下行控制信道的不同聚合等级上的盲检能力信息上报给基站。
具体的，终端分别上报不同聚合等级上的盲检能力信息；例如终端上报的内容包括：终端对聚合等级为1的PDCCH的盲检能力信息以及终端对聚合等级为2的PDCCH的盲检能力信息；其中，终端对聚合等级为1的PDCCH的盲检能力信息为：单位时间内终端对聚合等级为1的PDDCH的最大盲检次数为100；而终端对聚合等级为2的PDCCH的盲检能力信息为：单位时间内终端对聚合等级为2的PDCCH的最大盲检次数为80。
综上，本公开的上述实施例提供的盲检能力上报方法中，通过终端自主上报其自身的盲检能力信息，以辅助基站根据其盲检能力信息进行合理的盲检配置，以此适应多样化的业务需求以及终端类型多样化的需求。

例如终端上报的盲检能力信息为：终端在单位时间1ms内能够支持最大100次盲检，基站可以配置终端进行如下组合的盲检：

根据所述终端的盲检能力信息为所述终端的盲检行为配置至少一种盲检类型的盲检信息。
综上，本公开的上述实施例提供的基站中，基站接收到终端的盲检能力信息后根据其盲检能力信息进行合理的盲检配置，以此适应多样化的业务需求以及终端类型多样化的需求。
需要说明的是，本公开实施例提供的基站是与上述盲检配置方法相对应的基站，上述实施例的所有实现方式均适用于该基站实施例中，也能达到与其相同的技术效果。
如图10所示，本公开实施例还提供一种盲检方法，应用于终端，包括：
步骤1001，确定终端的盲检能力信息；其中，所述终端的盲检能力信息包括：单位时间内终端能够处理的最大盲检次数。
需要说明的是，终端的盲检能力信息具体指终端对下行控制信道PDCCH的盲检能力信息。其盲检能力信息由终端确定，终端可根据不同业务或不同终端成本的需求来确定不同终端的盲检能力信息。具体的，终端的盲检能力信息定义为单位时间内终端处理的最大盲检次数。
步骤1002，接收基站为所述终端的盲检行为配置的盲检信息。
终端根据基站配置的盲检信息能够确定基站配置的盲检次数以及在哪个位置对何种类型的上行控制信息进行盲检。通常情况下，基站配置的单位时间内的盲检次数总和小于或者等于终端在单位时间内能够处理的最大盲检次数，但是也存在特殊的情况；例如多个基站同时对终端的盲检行为进行配置，则存在基站配置的单位时间内的盲检次数总和大于终端在单位时间内能够处理的最大盲检次数的情况；再例如，一个基站对终端的盲检行为进行配置时由于其他因素的影响导致其配置的单位时间内的盲检次数总和大于终端在单位时间内能够处理的最大盲检次数；故本公开实施例中不对基站配置的单位时间内的盲检次数总和的大小进行具体限定。
步骤1003，若所述终端根据基站配置的盲检信息确定的单位时间内的盲检次数总和大于所述单位时间内终端能够处理的最大盲检次数，根据预设规则减少单位时间内的盲检次数，使得单位时间内的盲检次数总和小于或者等于单位时间内终端能够处理的最大盲检次数。
本步骤中，当基站配置的单位时间内的盲检次数总和大于单位时间内终端能够处理的最大盲检次数，终端通过预设规则对盲检次数进行减少。
步骤1004，根据减少后得到的盲检次数对下行控制信道进行盲检。
本步骤中，减少基站配置的盲检次数之后得到的盲检次数为终端实际的盲检次数，从而保证终端的实际盲检次数小于或者等于终端能够处理的最大盲检次数，避免给终端带来额外的盲检压力，保证每次盲检的可靠性。
具体的，本公开的上述实施例中，所述单位时间为一个或多个时隙slot；或者，所述单位时间为一个或多个子帧subframe；或者，所述单位时间为一个或多个短时隙mini-slot；或者，所述单位时间为一个预设时间段(该预设时间段可以为一绝对时间单位，例如1ms、2ms等)；或者，所述单位时间为一个或多个传输时间间隔TTI。
具体的，本公开的上述实施例中，所述最大盲检次数为一种或多种盲检类型的盲检次数的总和。
其中，所述盲检类型包括：基于公共搜索空间的下行控制信道的盲检、以时隙长度为间隔基于用户专用搜索空间的下行控制信道的盲检和/或以短时隙长度为间隔基于用户专用搜索空间的下行控制信道的盲检。
且在每一种盲检类型中，且盲检次数包括：终端在至少一个控制资源集的至少一个候选资源中对至少一种类型的下行控制信息进行解码的次数。
需要说明的是，终端能够在一个或多个控制资源集上进行PDCCH的盲检；和/或，终端能够在一个或者候选资源上进行PDCCH的盲检；和/或，终端能够对一种或多种类型的下行控制信息DCI进行解码。其控制资源集的数量、候选资源的数量、DCI的类型可由基站进行配置。
可选的，本公开的上述实施例中步骤1001包括：
分别确定终端在下行控制信道的不同聚合等级上的盲检能力信息；其中，终端在下行控制信道的不同聚合等级上具有相同的盲检能力信息，或者，终端在下行控制信道的不同聚合等级上具有不同的盲检能力信息。
若终端在下行控制信道的不同聚合等级上具有相同的盲检能力信息，即终端的盲检能力与PDCCH的聚合等级不相关，不区分PDCCH的聚合等级大小，不同聚合等级的盲检能力按照同等处理。
若终端在下行控制信道的不同聚合等级上具有不同的盲检能力信息，即终端的盲检能力与PDCCH的聚合等级相关，区分PDCCH的聚合等级大小，盲检能力定义到某一种或多个PDCCH聚合等级上支持的盲检能力；例如，终端对聚合等级为1的PDCCH的盲检能力信息为：单位时间内终端对聚合等级为1的PDDCH的最大盲检次数为100；而终端对聚合等级为2的PDCCH的盲检能力信息为：单位时间内终端对聚合等级为2的PDCCH的最大盲检次数为80。
需要说明的是，当终端的盲检能力与PDCCH的聚合等级相关时，并不限定每个聚合等级均对应不同的聚合能力，可以设定多个聚合等级具有相同的聚合能力，但并不是所有的聚合等级均具有相同的聚合能力。例如，终端对聚合等级为1、2和4的PDCCH的盲检能力相同，设为100；而终端对聚合等级8、16及32的PDCCH的盲检能力相同，设为200；此种情况下也认为终端的盲检能力与PDCCH的聚合等级相关。
进一步的，本公开的上述实施例中步骤1001之后，所述方法还包括：
将所述终端的盲检能力信息上报给基站；
相应的，步骤1002包括：
接收基站根据所述终端的盲检能力信息为所述终端的盲检行为配置的盲检信息。
即本公开的上述实施例中，终端可以将其盲检能力信息上报给基站，或者，终端也可以不将盲检能力信息上报给基站。当终端将盲检能力信息上报给基站时，基站参考终端的盲检能力信息为终端配置盲检信息；当终端不将其盲检能力信息上报给基站，基站则自行为终端配置盲检信息。
进一步的，本公开的上述实施例中所述预设规则包括：
对每种盲检类型的盲检次数进行线性减少；和/或，
对各种盲检类型进行优先级排序，对低优先级的盲检类型的盲检次数进行减少；和/或，
若终端被配置在多个载波上进行下行控制信道的盲检，根据所述多个载波的优先级，对低优先级的载波的盲检次数进行减少；即终端根据载波优先级，放弃部分低优先级的载波的盲检，保证实际盲检次数不超出最大盲检次 数；具体的，载波优先级的设定可以是Pcell高于Scell，或者按照服务小区指数(serving cell index)来确定载波优先级，在此不作具体限定。
进一步的，本公开的上述实施例中所述对每种盲检类型的盲检次数进行线性减少的步骤，包括：
对预设盲检类型的盲检次数进行线性减少后得到的盲检次数
Figure PCTCN2018091036-appb-000001
其中，M为基站配置的单位时间内的盲检次数总和；Z 1为基站配置的单位时间内的预设盲检类型的盲检次数Z 1；N为单位时间内终端能够处理的最大盲检次数；Z 2为对预设类型的盲检次数进行线性减少后得到的盲检次数。
具体的，
Figure PCTCN2018091036-appb-000002
表示对“Z 1×(N/M)”进行向下取整。例如，M等于120(其中，第一盲检类型的Z 1等于40，第二盲检类型的Z 1等于60，第三盲检类型的Z 1等于20)，N等于100，
则第一盲检类型的
Figure PCTCN2018091036-appb-000003
第二盲检类型的
Figure PCTCN2018091036-appb-000004
第三盲检类型的
Figure PCTCN2018091036-appb-000005
故减少后的实际盲检次数总和为33+50+16＝99，未超出终端在单位时间内的最大盲检次数N(100)。
更进一步的，本公开的上述实施例中所述对低优先级的盲检类型的盲检次数进行减少的步骤，包括：
对低优先级的盲检类型中的下行控制信息的类型进行减少，即放弃对某一种或几种类型的下行控制信息的盲检；和/或，
对低优先级的盲检类型中的候选资源的数量进行减少，即放弃对某一个或几种候选资源的盲检；和/或，
对低优先级的盲检类型中的控制资源集的数量进行减少，即放弃对某一个或几个控制资源集的盲检。
具体的，优先级的设定包括但不限于如下的形式：
优先级例一：基于公共搜索空间的下行控制信道的盲检(common PDCCH)优先级高于以短时隙长度为间隔基于用户专用搜索空间的下行控制信道的盲检(mini-slot based PDCCH)高于以时隙长度为间隔基于用户专用搜索空间的下行控制信道的盲检(slot-based PDCCH)。
优先级例二：mini-slot based PDCCH高于common PDCCH高于slot-based  PDCCH。
优先级例三：mini-slot based PDCCH高于slot-based PDCCH高于common PDCCH。或者，其他可能的优先级排序。
综上，本公开的上述实施例中当网络配置的盲检次数大于终端能够处理的最大盲检次数时，终端通过预设规则对盲检次数进行减少，从而保证终端的实际盲检次数小于或者等于终端能够处理的最大盲检次数，避免给终端带来额外的盲检压力，保证每次盲检的可靠性。
