Description

一种检测控制信道的方法及装置
本申请要求于2018年09月28日提交国家知识产权局、申请号为201811142573.2、申请名称为“一种检测控制信道的方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信技术领域，尤其涉及一种检测控制信道的方法及装置。
背景技术
在通信系统中，网络设备向终端设备传输数据的过程可以包括：网络设备先向终端设备发送包括下行控制信息(downlink control information，DCI)的物理下行控制信道(physical downlink control channel，PDCCH)，再向终端设备发送数据。在终端设备侧，终端设备会先在网络设备配置的搜索空间(search space)盲检网络设备下发的PDCCH，解调PDCCH中的DCI，再根据解调出的DCI在相应的资源位置上接收属于终端设备自己的数据(包括广播消息、寻呼、终端设备的数据等等)。由该过程可知，网络设备发送PDCCH的时间间隔(或频度)影响数据到达终端设备的时间间隔，网络设备发送PDCCH间隔越短，数据到达终端设备的时间间隔越短；反之，则数据到达终端设备的时间间隔越长，同时网络设备发送PDCCH的时间间隔影响终端设备的接收功率消耗，网络设备发送的PDCCH的时间间隔越小，终端设备在单位时间内需要检测PDCCH的次数越多，从而耗费的接收功率越大，反之亦然。
目前，不同数据的传输质量要求是不同的。例如，高可靠低时延通信(ultra reliable and low latency communication，URLLC)数据要求低时延、高可靠等(如时延要求在1ms或者0,5ms或者更低，可靠性要求数据包正确率为99.999％)，增强型移动带宽(enhanced mobile broadband，eMBB)数据对时延要相对较低(如：时延要求在4ms或者更高，可靠性要求数据包正确率为90％)。因此，为了满足不同数据的传输时延，终端设备盲检用于调度URLLC数据的PDCCH的频度要快，而盲检用于调度eMBB数据的PDCCH的频度可以相对慢些。
但是，现有针对不同的数据，网络设备为终端设备配置的搜索空间是相同，即终端设备盲检用于调度URLLC数据的PDCCH的频度和盲检用于调度eMBB的PDCCH的频度是相同。此时，终端设备盲检PDCCH的频度以eMBB数据高时延的要求进行设置，则不满足URLLC数据的低时延要求；或者终端设备盲检PDCCH的频度以URLLC数据低时延的要求进行设置，则浪费eMBB的检测资源。
发明内容
本申请实施例提供一种检测控制信道的方法及装置，以满足不同类型数据的传输要求。
为达到上述目的，本申请实施例采用如下技术方案：
第一方面，提供一种检测控制信道的方法，该方法包括：接入网设备为终端设备配置至少一个控制信道资源集合以及至少两个检测时机，通过至少一个控制信道资源集合中每个控制信道资源集合所对应的一个或多个控制信道向终端设备发送调度信息；其中，至少 一个控制信道资源集合中的每个控制信道资源集合对应一个或多个控制信道；至少两个检测时机中的每个检测时机都不相同，每个检测时机用于终端设备检测至少一个控制信道资源集合中的每个控制信道资源集合所对应的一个或多个控制信道。
需要说明是，本申请实施例所述的调度信息可以用于调度业务数据，如：可以为DCI，控制信道是指承载调度信息的控制信道，这些控制信道是基于特定终端设备(user equipment，UE)的配置。示例性的，承载不同业务调度信息的控制信道的名称可以是相同的，比如：均可以命名为PDCCH，或者，承载不同业务调度信息的控制信道的名称也可以不同，比如：调度eMBB业务的控制信道命名为PDCCH，调度URLLC业务的控制信道命名为newPDCCH。本申请实施例所述的控制信道资源集合的配置信息和检测时机的配置信息可以携带在同一配置消息中配置给终端，也可以先配置控制信道资源集合，然后再配置检测时机，或者，先配置检测时机后配置控制信道资源集合，不做限制。
基于第一方面提供的方法，可以为终端设备配置不同的检测时机，使终端设备根据不同的检测时机检测一个或多个控制信道，如：对于时延要求低的数据对应的控制信道的检测频率可以设置的高一点，对于时延相对要求不高的数据对应的控制信道的检测频率可以设置的相对低一点，满足不同类型数据的传输要求。同时，针对不同检测时机，可以用特定的RNTI或/和解调格式检测控制信道，从而节省终端设备的接收功耗。
在一种可能的设计中，所述方法包括：接入网设备为终端设备配置第一参数信息；其中，第一参数信息用于指示所述一个或多个控制信道中的至少一个控制信道的处理格式，处理格式包括编码格式和/或调制格式，至少一个控制信道资源集合中每个控制信道资源集合所对应的一个或多个控制信道的处理格式不同。基于上述方法，可以为终端设备指示不同控制信道的编码格式/调制格式，使终端设备按照指示的编码格式和/或调制格式检测控制信道。同时，不同控制信道的编码格式和/或调制格式不同可以保证调度数据的准确性。
在一种可能的设计中，所述方法还包括：接入网设备向终端设备发送指示信息；其中，指示信息用于指示调度信息调度的数据占用的最大带宽。基于上述方法，可以通过向终端设备指示发送的数据的带宽，使终端设备根据该指示调整其接收带宽，不会导致终端设备的接收带宽过大，降低终端设备的接收功耗。
在一种可能的设计中，至少两个检测时机分别对应高可靠低时延通信(ultra reliable and low latency communication，URLLC)业务和增强型移动带宽(enhanced mobile broadband，eMBB)业务。基于上述方法，可以针对URLLC业务和eMBB业务配置不同的检测时机，使终端设备在不同检测时机检测调度URLLC业务的控制信道和调度eMBB业务的控制信道，保证检测满足数据的传输质量要求。
在一种可能的设计中，调度eMBB业务的调度信息采用小区无线网络临时标识(cell radio network temporary identifier，C_RNTI)加扰，调度URLLC业务的调度信息采用MCS-C-RNTI加扰。基于上述方法，可以针对调度URLLC业务或eMBB业务的调度信息采用不同的RNTI进行加扰。
在一种可能的设计中，URLLC业务的检测周期小于eMBB业务的检测周期。基于上述方法，可以将URLLC业务对应的控制信道的检测频率设置的高一点，满足URLLC业务的低时延要求，而对于eMBB业务，将eMBB业务对应的控制信道的检测频率设置的低一点，不浪费检测资源。
在一种可能的设计中，当至少一个控制信道资源集合中每个控制信道资源集合所对应的一个或多个控制信道需要重传时，其重传资源与初传资源的复用关系采用载波间频分复用关系或载波内频分复用关系。基于上述方法，可以对某些控制信道进行重传，保证了控制信道调度的数据的可靠性；同时，重传资源与初传资源的复用关系采用载波间频分复用关系或载波内频分复用关系，当重传资源与初传资源采用载波间频分复用时，可以提高了频分分集效果；当重传资源与初传资源采用载波内频分复用时，可以减少终端设备的接收带宽，进而减少终端设备的接收功率。
第二方面，提供一种检测控制信道的方法，所述方法包括：终端设备接收至少一个控制信道资源集合的配置信息以及至少两个检测时机的配置信息，根据至少两个检测时机检测每个控制信道资源集合所对应的一个或多个控制信道；其中，至少一个控制信道资源集合中的每个控制信道资源集合与一个或多个控制信道对应；至少两个检测时机中的每个检测时机都不相同，每个检测时机用于终端设备检测至少一个控制信道资源集合中的每个控制信道资源集合所对应的一个或多个控制信道。
基于第二方面提供的方法，终端设备可以根据不同的检测时机检测一个或多个控制信道，如：对于时延要求低的数据对应的控制信道可以检测的快点，对于时延相对要求不高的数据对应的控制信道的检测频率可以检测的慢点，满足不同业务数据的传输要求。
在一种可能的设计中，所述方法还包括：终端设备获取第一参数信息；其中，第一参数信息用于指示所述一个或多个控制信道中的至少一个控制信道的处理格式，处理格式包括编码格式和/或调制格式，至少一个控制信道资源集合中的每个控制信道资源集合所对应的一个或多个控制信道的处理格式不同；终端设备根据至少两个检测时机检测每个控制信道资源集合所对应的一个或多个控制信道，包括：终端设备在至少两个检测时机，根据第一参数信息所指示的处理格式检测一个或多个控制信道。基于上述方法，可以为终端设备指示不同控制信道的编码格式/调制格式，使终端设备按照指示的编码格式和/或调制格式检测控制信道。同时，不同控制信道的编码格式和/或调制格式不同可以保证调度数据的准确性。
在一种可能的设计中，所述方法还包括：终端设备接收指示信息；其中，指示信息用于指示接入网设备向终端设备调度的数据占用的最大带宽。基于上述方法，可以使终端设备根据指示调整其接收带宽，不会导致终端设备的接收带宽过大，降低终端设备的接收功耗。
在一种可能的设计中，至少两个检测时机分别对应URLLC业务和eMBB业务。基于上述方法，可以针对URLLC业务和eMBB业务配置不同的检测时机，使终端设备在不同检测时机检测调度URLLC业务的控制信道和调度eMBB业务的控制信道，保证检测满足数据的传输质量要求。
在一种可能的设计中，所述eMBB业务对应的控制信道采用小区无线网络临时标识C_RNTI检测；所述URLLC业务对应的控制信道采用调制与编码策略小区无线网络临时标识MCS-C-RNTI检测。基于上述方法，可以针对URLLC业务和eMBB业务采用不同的RNTI进行解扰，
在一种可能的设计中，URLLC业务的检测周期小于eMBB业务的检测周期。基于上述方法，可以将URLLC业务对应的控制信道的检测频率设置的高一点，满足URLLC业 务的低时延要求，而对于eMBB业务，将eMBB业务对应的控制信道的检测频率设置的低一点，不会浪费检测资源。
在一种可能的设计中，当至少一个控制信道资源集合中每个控制信道资源集合所对应的一个或多个控制信道需要重传时，其重传资源与初传资源的复用关系采用载波间频分复用关系或载波内频分复用关系。基于上述方法，可以对某些控制信道进行重传，保证了控制信道调度的数据的可靠性；同时，重传资源与初传资源的复用关系采用载波间频分复用关系或载波内频分复用关系，当重传资源与初传资源采用载波间频分复用时，可以提高了频分分集效果；当重传资源与初传资源采用载波内频分复用时，可以减少终端设备的接收带宽，进而减少终端设备的接收功率。

具体实施方式
首先，为了便于理解本申请实施例，对本申请实施例涉及的一些名词进行描述：
控制信道资源集合：可以称为控制资源集(control resource set，CORESET)，控制信道资源集合对应一个或多个控制信道(如：PDCCH)。本申请实施例中，控制信道资源集合对应一个或多个控制信道可以指：控制信道资源集合可以被一个或多个控制信道占用(或使用)。
控制信道资源集合可以包括以下任一种或多种配置信息：控制信道可能占用的频域资源(frequency domain resources)、控制信道可能占用的时间域时长(duration)等。其中，时间域时长可以称为时域资源，该时域资源是连续的，该时域资源可以以正交频分复用(orthogonal frequency division multiplexing，OFDM)符号(简称symbols)为单位。
示例性的，控制信道资源集合可以包括如图1所示的1个symbol或2个symbols或3个symbols等。其中，控制信道资源集合可以用控制信道资源集合标识(indentity，ID)所标识，不同控制信道资源集合对应的控制信道资源集合ID可能是不同的。如：包括1个symbol的控制信道资源集合可以用控制信道资源集合1标识，包括2个symbols的控制信道资源集合可以用控制信道资源集合2标识。
检测时机：可以称为搜索空间(search space)或者发送/接收控制信道的时间机会，其定义了终端设备检测控制信道(如：PDCCH)的范围和机会(occasion)，检测时机可以包括以下任一种或者多种配置信息：控制信道资源集合标识、检测周期和偏移量(monitoring slot periodicity and offset)、连续监听的时隙(slot)个数、一个slot内监听的符号位置。需要说明的是，本申请实施例所述的检测时机，不仅是指一个检测机会，还可以是一个包括多个检测机会点的检测机会图案，检测机会点可以指检测控制信道的机会点。
其中，控制信道资源集合标识如前所述。检测周期可以用于规定终端设备每隔多长时间(或多少个连续的slot)监听一次控制信道，偏移量可以指终端设备首次监听控制信道的起始时隙与第0个slot(即slot0)间的偏移量。连续监听的时隙(slot)个数可称为监听长度(duration)，可以指终端设备每次需要在连续的几个slot内监听控制信道。一个slot内监听的符号位置可以称为slot内的检测位置，可以用于指示终端设备从一个slot内的哪些符号开始监听控制信道。
例如，以控制信道为PDCCH、slot包括14个symbols为例，假设检测时机的配置信息为：控制信道资源集合标识所指示的控制信道资源集合包括2个symbols(即PDCCH可能占用2个symbols)，检测周期为5个slot，偏移量为0slot，连续监听的slot的个数为2 次，每个slot内开始监听PDCCH的符号位置为第1个symbols(即符号0)、第8个symbols(即符号7)，则在图2所示的从slot0到slot9的九个slots中，以5个slots为一个检测周期，共存在两个检测周期：从slot0到slot4的第一个检测周期，从slot5到slot9为第二个检测周期，第一个检测周期内，终端设备可以在slot0、slot1上监听PDCCH，在第二个检测周期内，终端设备可以在slot5、slot6上监听PDCCH。因每个监听的slot内开始检测PDCCH的检测位置为符号0、符号7，且PDCCH连续可能占用2个symbols。以终端设备可以在slot5上监听PDCCH为例，如图2所示，终端设备可以在slot5的符号0、符号1、符号7、符号8上监听PDCCH。
下面结合附图对本申请实施例的实施方式进行详细描述。
本申请实施例提供的检测控制信道的方法可以应用于图3所示的通信系统中，该通信系统可以为长期演进(long term evolution，LTE)系统，还可以为第五代(5th generation，5G)移动通信系统或者新空口(new radio，NG)系统，也可以为其他移动通信系统，不予限制。如图3所示，该通信系统可以包括接入网设备以及终端设备，终端设备可以通过无线方式与接入网设备间相互传输不同类型的数据(如：URLLC数据或者eMBB数据等)。例如，接入网设备可以向终端设备发送控制信道(如：PDCCH)，该控制信道可以包括下行控制信息(downlink control information，DCI)，终端设备可以按照搜索空间的规定检测接入网设备发送的控制信道，在该控制信道包括的DCI所指示的调度资源上接收接入网设备发送给终端设备的数据。需要说明的是，图3仅为示例性框架图，图3包括的设备的数量不受限制，且除图3所示功能节点外，图3所述系统还可以包括其他节点，如：核心网设备、网关设备、应用服务器等等，不予限制。
示例性的，图3中的终端设备可以称为终端(terminal)或者用户设备(user equipment，UE)或者移动台(mobile station，MS)或者移动终端设备(mobile terminal，MT)等，可以被部署在水面上(如轮船等)；还可以被部署在空中(例如飞机、气球和卫星上等)。具体的，可以为可以是手机(mobile phone)、平板电脑或带无线收发功能的电脑。终端设备还可以是虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制中的无线终端设备、无人驾驶中的无线终端设备、远程医疗中的无线终端设备、智能电网中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本申请实施例中，用于实现终端设备的功能的装置可以是终端设备，也可以是能够支持终端设备实现该功能的装置，例如芯片系统。本申请实施例中，芯片系统可以由芯片构成，也可以包括芯片和其他分立器件。本申请实施例提供的技术方案中，以用于实现终端设备的功能的装置是终端设备为例，描述本申请实施例提供的技术方案。
图3中的接入网设备可以称为网络设备，主要用于实现无线物理控制功能、资源调度和无线资源管理、无线接入控制以及移动性管理等功能。具体的，该接入网设备可以为接入网(access network，AN)/无线接入网(radio access network，RAN)设备，还可以为由多个5G-AN/5G-RAN节点组成的设备，又可以为者基站(nodeB，NB)、演进型基站(evolution nodeB，eNB)、下一代基站(generation nodeB，gNB)、收发点(transmission receive point，TRP)、传输点(transmission point，TP)以及某种其它接入节点中的任一节点。本申请实施例中，用于实现接入网设备的功能的装置可以是接入网设备，也可以是能够支持接入网 设备实现该功能的装置，例如芯片系统。在本申请实施例提供的技术方案中，以用于实现接入网设备的功能的装置是接入网设备为例，描述本申请实施例提供的技术方案。
在图3所示系统中，接入网设备可以预先为终端设备配置控制信道资源集合和检测时机，以便终端设备根据不同的检测时机检测不同的控制信道。具体的，该方法如图4所示，可以包括S401～S404：
S401：接入网设备为终端设备配置至少一个控制信道资源集合。
其中，终端设备可以为图3所示系统中的任一终端设备。控制信道资源集合的相关描述以及配置信息如前所述。至少一个控制信道资源集合中的每个控制信道资源集合对应一个或多个控制信道。
示例性的，不同控制信道资源集合对应的控制信道所调度的数据的QoS要求可以是不同的。本申请各实施例中，QoS要求可以称为传输质量要求，可以包括以下任一种或多种要求：传输时延、传输可靠度、传输速率、传输误码率、解调/调制时使用的调制与编码策略(modulation and coding scheme，MCS)索引表等。.
示例性的，接入网设备为终端设备配置至少一个控制信道资源集合可以指：接入网设备为终端设备配置一个控制信道资源集合，或者配置两个控制信道资源集合，或者三个控制信道资源集合等等，本申请实施例不限定控制资源控制集合的个数。
在本申请实施例中，接入网设备可以通过高层信令为终端设备配置至少一个控制信道资源集合。其中，高层信令可以为无线资源控制(radio resource control，RRC)信令，接入网设备可以将至少一个控制信道资源集合的配置信息携带在RRC信令中发送给终端设备。
S402：所述接入网设备为所述终端设备配置至少两个检测时机。
示例性的，接入网设备为终端设备配置至少两个检测时机可以指：所述接入网设备为所述终端设备配置两个检测时机，或者三个检测时机，或者配置四个检测时机等等，本申请实施例不限定检测时机的个数。
其中，至少两个检测时机可以分别对应URLLC业务和eMBB业务，至少两个检测时机中的每个检测时机可以都不相同，每个检测时机可以用于终端设备检测至少一个控制信道资源集合中的每个控制信道资源集合所对应的一个或多个控制信道。如：假设接入网设备为终端设备配置两个控制信道资源集合：CORESET1、CORESET2，三个检测时机：检测时机1～检测时机3，终端设备可以根据检测时机1检测CORESET1中的控制信道，根据检测时机2检测CORESET1中的控制信道，根据检测时机3上检测CORESET2中的控制信道。

需要说明的，本申请实施例不限定S401和S402的执行顺序，S401和S402可以如图4所示先后执行；也可以先执行S402，再执行S401；还可以同时执行S401以及S402，如：接入网设备可以将至少一个控制信道资源集合的配置信息以及至少两个检测时机的配置信息携带在RRC信令中一起发送给终端设备。
S403：所述接入网设备通过至少一个控制信道资源集合中每个控制信道资源集合所对应的一个或多个控制信道向所述终端设备发送调度信息。
以接入网设备通过一个控制信道资源集合所对应的一个控制信道向终端设备发送调度信息为例，所述接入网设备通过该控制信道资源集合所对应的一个控制信道向终端设备发送调度信息可以包括：所述接入网设备生成用于调度数据的调度信息(如：DCI)，将DCI进行循环冗余码校验(cyclic redundancy check，CRC)校验、RNTI加扰、信道编码、调制、资源映射等处理得到控制信道，将所述控制信道包括在控制信道资源集合中向终端设备发送，以及在DCI所指示的时频资源位置上向终端设备发送数据。具体的，CRC校验、RNTI加扰、信道编码、调制、资源映射等处理过程可参照现有技术，不再详述。
本申请实施例中，不同QoS要求的数据对应的调度信息在进行RNTI加扰时所使用的RNTI可以是不同的或者相同的。示例性的，调度eMBB业务的调度信息在进行RNTI加扰时采用C_RNTI加扰，调度URLLC业务的调度信息在进行RNTI加扰时采用MCS-C-RNTI加扰。
S404：所述终端设备根据所述至少两个检测时机检测每个控制信道资源集合所对应的一个或多个控制信道。
示例性的，终端设备可以在检测时机所配置的检测周期内，在控制信道资源集合对应的资源上通过资源解映射、解调、信道译码、RNTI解扰、CRC校验等处理解调控制信道包括的DCI。示例性的，终端设备采用C_RNTI对eMBB业务对应的控制信道进行RNTI解扰，采用MCS-C-RNTI对URLLC业务对应的控制信道进行RNTI解扰。
基于图4所示方法，可以为终端设备配置不同的检测时机，使终端设备可以根据不同的检测时机检测一个或多个控制信道，如：对于时延要求低的数据对应的控制信道的检测频率可以设置的高一点，对于时延相对要求不高的数据对应的控制信道的检测频率可以设置的相对低一点，满足不同业务数据的传输要求。
进一步的，在图4所示方法中，所述方法还可以包括：
接入网设备为终端设备配置第一参数信息，终端设备获取第一参数信息。
其中，接入网设备可以通过RRC信令为终端配置第一参数信息，第一参数信息可以与S401和/或S402中的配置信息一起配置给终端设备。
第一参数信息可以用于指示所述一个或多个控制信道中的至少一个控制信道的处理格式，如：可以用于一个或多个控制信道中一个控制信道的处理格式，或者两个控制信道的处理格式，或者三个、四个等。处理格式可以包括编码格式和/或调制格式，所述一个或多个控制信道的处理格式可以不同或相同。示例性的，调度不同QoS要求的数据的控制信道的处理格式是不同的。如：调度eMBB业务的调度信息采用四相相移键控(quadrature phase shift keying，QPSK)调制，调度URLLC业务的调度信息可以采用比QPSK解调性能更好的调制方式，如：二相相移键控信号(binary phase shift keying，BPSK)调制。或者，调度URLLC业务的调度信息可以采用BPSK调制方式进行调制，而调度eMBB业务的调度信息采用默认调制方式。
如此，终端设备可以在至少两个检测时机所规定的检测时机到达时，根据第一参数信息所指示的处理格式检测控制信道，提高控制信道检测的准确性和效率。
进一步的，在图4所示方法中，所述方法还可以包括：
接入网设备向终端设备发送指示信息，终端设备接收接入网设备发送的指示信息。
其中，指示信息可以用于指示控制信道调用的数据占用的最大带宽，该带宽可以不大于包括控制信道的控制信道资源集合的带宽。
如此，终端设备可以按照接入网设备指示的带宽调整接收机的接收功率，接收接入网设备发送的数据，降低终端设备的接收功耗。
进一步的，在图4所示方法中，所述方法还可以包括：
当至少一个控制信道资源集合中每个控制信道资源集合所对应的一个或多个控制信道需要重传时，其重传资源与初传资源的复用关系采用载波间频分复用关系或载波内频分复用关系。
示例性的，若控制信道调度的数据的可靠性要求较高，则该控制信道需要重传。
其中，重传资源与初传资源采用载波间频分可以指：重传资源和初传资源可以为不同载波，或者不同载波上的带宽部分(bandwidth part，BWP)；如此，初传和重传控制信道时配置在不同载波上，初传资源和重传资源频域间隔较大，提高了频分分集效果。
重传资源与初传资源采用载波内频分复用可以指：重传资源和初传资源可以为同一载波内的不同频段，或者同一载波上的不同BWP。如此，初传和重传控制信道时配置在同一载波上，初传资源和重传资源频域间隔较小，减少终端设备的接收带宽，从而减少终端设备的接收功耗。
下面以控制信道资源集合为CORESET，检测时机为搜索空间，接入网设备为终端设备配置两个CORESET：第一CORESET和第二CORESET，为终端设备配置两个搜索空间：第一搜索空间和第二搜索空间，第一CORESET对应第一控制信道，第二CORESET对应第二控制信道，第一控制信道用于调度URLLC业务的数据(简称URLLC数据)，第二控制信道用于调度eMBB业务的数据(简称eMBB数据)为例，对图4所示方法进行描述。
其中，URLLC数据的传输时延、传输可靠度、传输速率、传输误码率与eMBB数据的传输时延、传输可靠度、传输速率、传输误码率是不同的。示例性的，URLLC数据的传输时延小于或等于1ms，传输误块率为0.00001等。eMBB数据的传输时延小于或等于4ms，传输误块率为0.1。需要说明的是，本申请实施例仅以eMBB数据和URLLC数据为例进行说明，配置其他不同其他类型数据对应的CORESET和搜索空间的方法的配置也可参照本申请实施例提供的方法，比如：机器类型通信(machine-type communication，MTC)数据相比eMBB数据有不同的QoS要求，语音类数据和数据类数据相比，也有不同的QoS要求，配置这些数据对应的控制信道的CORESET和搜索空间的方法时，也可以根据数据的QoS要求进行配置。
为了更好的理解本申请的技术方案，控制信道资源集合以第一CORESET和第二CORESET为例，检测时机以第一搜索空间与第二搜索空间为例进行说明，如图5所示，为本申请实施例提供的一种检测控制信道的方法流程图，该方法可以包括S501～S504。
S501：所述接入网设备为所述终端设备配置第一CORESET和第二CORESET。
其中，第一CORESET和第二CORESET可以相同或不同。示例性的，第一CORESET的时域长度可以为2个符号，第二CORESET的时域长度可以为3个符号。
S502：所述接入网设备为所述终端设备配置第一搜索空间以及第二搜索空间。
其中，第一搜索空间可以用于终端设备检测第一控制信道,。第二搜索空间可以用于终 端设备检测第二控制信道。
为了满足URLLC数据和eMBB数据的传输质量要求，第一搜索空间与第二搜索空间是不同的。示例性的，因URLLC数据要求低时延，所以，为URLLC数据配置的第一搜索空间中检测周期比较短，相对的，eMBB数据对时延要求不高，则为eMBB数据配置的第二搜索空间中检测周期可以稍微长些等，即URLLC数据的检测周期小于eMBB数据的检测周期。
需要说明的，本申请实施例不限定S501和S502的执行顺序，S501和S502可以如图5所示先后执行；也可以先执行S502，再执行S501；还可以同时执行S501以及S502。
S503：所述接入网设备通过第一CORESET对应的第一控制信道或者第二CORESET中对应的第二控制信道向所述终端设备发送调度信息。
其中，所述接入网设备向所述终端设备发送什么样的控制信道以及调度什么类型的数据由接入网设备决定，对于所述终端设备而言，这些信息是未知的，需要通过检测控制信道获知。
如前所述，以接入网设备通过第一CORESET对应的第一控制信道向终端设备发送调度URLLC数据的调度信息为例，所述接入网设备可以生成用于调度URLLC数据的DCI，将所述DCI经过CRC校验、RNTI加扰、信道编码、调制、资源映射等处理得到第一控制信道，将所述第一控制信道包括在第一CORESET中向所述终端设备发送，以及在该DCI所指示的时频资源位置上向所述终端设备发送URLLC数据。其中，所接入网设备可以先向终端设备发送第一控制信道，再向终端设备发送URLLC数据。示例性的，所述接入网设备发送第一控制信道与URLLC数据的时间间隔可以大于所述终端设备成功解调出第一控制信道的时长。
S504：所述终端设备在第一搜索空间或第二搜索空间检测第一CORESET对应的第一控制信道或者第二CORESET对应的第二控制信道。
示例性的，当第一控制信道的检测机会到达时，终端设备根据第一搜索空间的配置检测第一控制信道，如：在第一CORESET配置的资源上通过资源解映射、解调、信道译码、RNTI解扰、CRC校验等处理解调第一控制信道包括的DCI。当第二控制信道的检测机会到达时，终端设备根据第二搜索空间的配置检测第二控制信道，如：在第二CORESET配置的资源上通过资源解映射、解调、信道译码、RNTI解扰、CRC校验等处理解调第二控制信道包括的DCI。
其中，因URLLC数据的传输质量要求相对于eMBB数据的传输质量要求高，URLLC数据的业务优先级相对于eMBB数据的业务优先级高，所以终端设备根据第一搜索空间的配置检测第一控制信道时，可以启动较多的计算资源去检测第一控制信道，如：1)启用较多计算单元数，比如：额外启动数字信号处理(digital signal processing，DSP)核进行数据处理；2)利用提频技术将运算频率提高。比如：通常情况下运行频率是800MHz，当对第一控制信道进行检测时，频率提高到1.5GHz；3)运算资源借用：借用其他载波或者系统的运算资源等。而终端设备根据第二搜索空间的配置检测第二控制信道时，可以启动较少的计算资源去检测第二控制信道，如：将DSP核处于休眠或者未上电状态等。
需要说明的是，若第一检测机会与第二检测机会重叠时，即有第一控制信道的检测时机到来，也有第二控制信道的检测时机到来时，终端设备优先检测调度传输质量要求较高 的数据的控制信道，如：会优先检测业务优先级高的第一控制信道，以兼顾URLLC数据的低时延要求。
后续，当终端设备根据第一搜索空间成功解调出第一控制信道时，终端设备根据第一控制信道包括的DCI接收接入网设备发送的URLLC数据。或者，当终端设备根据第二搜索空间成功解调出第二控制信道时，终端设备根据第二控制信道包括的DCI接收接入网设备发送的eMBB数据。
如图6a所示，以slot包括14个symbols，调度URLLC数据的PDCCH为PDCCH1，调度eMBB数据的PDCCH为PDCCH2为例，假设接入网设备配置给终端设备的CORESET为：eMBB数据的CORESET中时域长度为3个符号，URLLC数据对应的CORESET中时域长度为2个符号，eMBB数据对应的搜索空间的配置为：检测周期为5个slot，偏移量为0，持续监听的slot个数为1，1个slot内置有1个检测起始符号位(起始符号为0符号)；URLLC数据对应的搜索空间的配置为：URLLC的检测周期为5个slot，偏移量为0，持续监听的slot个数为2，1个slot内置有2个检测起始符号位(起始符号为0和7符号)，则在如图6a所示的从slot0到slot14的十五个slots中，以5个slots为一个检测周期，共存在三个检测周期：从slot0到slot4的第一个检测周期，从slot5～slot9的第二个检测周期，从slots10～slot14的第三个检测周期。在第一个检测周期内，终端设备可以在slot0、slot1上监听PDCCH1，可以在slot0上监听PDCCH2。在第二个检测周期内，终端设备可以在slot5、slot6上监听PDCCH1，可以在slot5上监听PDCCH2。在第二个检测周期内，终端设备可以在slot10、slot11上监听PDCCH1，可以在slot10上监听PDCCH2。因slot内开始检测PDCCH1的检测位置为符号0、符号7，且PDCCH1连续可能占用2个symbols，则如图6a所示，终端设备在slot5上监听PDCCH1时，可以在slot5内的符号0和符号1、符号7和符号8上监听PDCCH1。终端设备在slot11上监听PDCCH1时，可以在slot11内的符号0和符号1、符号7和符号8上监听PDCCH1。因slot内开始检测PDCCH2的检测位置为符号0，且PDCCH2连续可能占用3个symbols，则如图6a所示，终端设备在slot5上监听PDCCH2时，可以在slot5内的符号0、符号1、符号2上监听PDCCH2。
如图6b所示，以slot包括14个symbols，调度URLLC数据的PDCCH为PDCCH1，调度eMBB数据的PDCCH为PDCCH2为例，假设接入网设备配置的eMBB数据、URLLC数据对应的CORESET均为2个符号，eMBB数据对应的搜索空间的配置为：检测周期为5个slot，偏移量为0，持续监听的slot个数为1，1个slot内置有1个检测起始符号位(起始符号为0符号)；URLLC数据对应的搜索空间的配置为：URLLC的检测周期为5个slot，偏移量为0，持续监听的slot个数为2，1个slot内置有2个检测起始符号位(起始符号为0和7符号)，则在如图6b所示的从slot0到slot14的十五个slots中，以5个slots为一个检测周期，共存在三个检测周期：从slot0到slot4的第一个检测周期，从slot5～slot9的第二个检测周期，从slots10～slot14的第三个检测周期。在第一个检测周期内，终端设备可以在slot0、slot1上监听PDCCH1，可以在slot0上监听PDCCH2。在第二个检测周期内，终端设备可以在slot5、slot6上监听PDCCH1，可以在slot5上监听PDCCH2。在第二个检测周期内，终端设备可以在slot10、slot11上监听PDCCH1，可以在slot10上监听PDCCH2。因slot内开始检测PDCCH1的检测位置为符号0、符号7，且PDCCH1连续可能占用2个symbols，则如图6b所示，终端设备在slot5上监听PDCCH1时，可以在slot5内的符号0 和符号1、符号7和符号8上监听PDCCH1。终端设备在slot11上监听PDCCH1时，可以在slot11内的符号0和符号1、符号7和符号8上监听PDCCH1。因slot内开始检测PDCCH2的检测位置为符号0，且PDCCH2连续可能占用2个symbols，则如图6b所示，终端设备在slot5上监听PDCCH2时，可以在slot5内的符号0、符号1上监听PDCCH2，此时，PDCCH1和PDCCH2的检测时机是重叠的。
基于图5所示方法，将不同业务类型对应的搜索空间分开配置，对时延要求不高、优先级较低的数据对应的搜索空间配置的检测周期将长，可以有效的减少检测控制信道的次数，同时，终端能够根据搜索空间的配置信息可以识别搜索空间对应的控制信道的类型，便于终端集中调度控制信道的计算资源或者释放控制信道的一些计算资源等。
进一步的，因URLLC业务的数据的可靠性要求相对于eMBB数据的可靠性传输较高，则图5所示方法还可以包括：
接入网设备向终端设备重传第一控制信道。
其中，第一控制信道的重传资源与初传资源的复用关系可以如前所述，采用载波间频分复用关系或载波内频分复用关系，还可以采用时分复用关系，也可以采用时分复用和频分复用关系等。可选的，重传资源与初传资源采用时分复用关系，重传资源与初传资源占用的符号长度可能是不同的。
例如，如图7a所示，重传资源和初传资源间采用载波内频分复用，如：重传资源和初传资源为同一BWP带宽中的不同频段，或者，重传资源和初传资源为同一载波带宽中的不同频段。如图7b所示，重传资源和初传资源间采用载波间频分复用，如：重传资源位于载波2带宽上，初传资源位于载波1带宽上；或者，重传资源位于BWP2带宽上，初传资源位于BWP1带宽上。如图7c所示，重传资源和初传资源间采用时分复用时，此时，重传资源和初传资源均占用2个symbols。如图7d所示，重传资源和初传资源间采用时分复用时，此时，初传资源占用2个symbols、重传资源占用1个symbols。
需要说明的是，上述仅给出了控制信道一次重传的例子，在实际应用中，可能会多次重传控制信道，当多次重传控制信道时，重传资源与之前传输时的资源的复用关系可以为载波间频分复用关系或载波内频分复用关系或时分复用关系或时分复用和频分复用关系等，不予限制。
示例性的，在接入网设备向终端设备重传第一控制信道之前，接入网设备还需要为终端设备重新配置用于检测重传的第一控制信道的搜索空间，如：第三搜索空间。其中，第三搜索空间的配置信息可以独立发送给终端设备，也可以携带在第一搜索空间的配置信息中一个发送给终端设备，即第一搜索空间可以包括用于检测接入网设备重传的第一控制信道的搜索空间的配置信息。如：第一搜索空间包括的配置信息可以包括下述一种或多种；初传CORESET标识、重传COESET标识、初传第一控制信道的检测周期、重传第一控制信道的检测周期、初传第一控制信道与重传第一信道的时间偏移量、初传第一控制信道时时隙内需要检测的位置或重传第一控制信道时时隙内需要检测的位置等。
其中，初传第一控制信道的检测周期和重传第一控制信道的检测周期可以相同。初传第一控制信道时时隙内需要检测的位置和重传第一控制信道时时隙内需要检测的位置可以相同。初传第一控制信道与重传第一控制信道的时间偏移量可以为：检测重传的第一控制信道的起始符号相对于检测初传的的第一控制信道的起始符号的偏移量。
