根据本发明其中一实施例，提供了一种控制信道的确定方法的实施例，需要说明的是，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，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。下面从终端侧对本发明实施例的终端设备的控制信道的确定方法进行介绍。图1是根据本发明实施例的一种控制信道的确定方法的流程图。如图1所示，该方法包括如下步骤：
步骤S102，终端接收至少一个第一控制资源集合CORESET信息。
在本发明上述步骤S102提供的技术方案中，终端可以接收网络设备下发的至少一个第一CORESET信息，该至少一个第一CORESET信息可以包括于搜索空间(search space)的配置信息中，其中，搜索空间可以由网络设备通过无线资源控制(Radio Resource Control，简称为RRC)信令通知给终端，以指示终端在相应的时频资源上检测物理下行控制信道PDCCH。
该实施例的至少一个第一CORESET信息用于承载PDCCH在频域上占用的资源块(RB)和时域上占用的正交频分复用(Orthogonal Frequency Division Multiplexing)，简称为OFDM)符号数等信息，不同的第一CORESET信息之间可以进行跳频，其中，网络设备可以为基站。
步骤S104，终端根据至少一个第一CORESET信息和第一资源，确定第一资源对应的至少一个第二CORESET信息。
在本发明上述步骤S104提供的技术方案中，在终端接收至少一个第一控制资源集合CORESET信息之后，终端根据至少一个第一CORESET信息和第一资源，确定第一资源对应的至少一个第二CORESET信息，也即，该实施例的至少一个第一CORESET信息是可以切换到至少一个第二CORESET信息的。
在该实施例中，第一资源可以包括第一时域资源或第一频域资源。其中，终端可以获取第一时域资源，该第一时域资源可以为时间单元(时刻)，根据接收到的至少一个第一CORESET信息和第一时域资源确定与第一时域资源对应的至少一个第二CORESET信息；或者，终端可以获取第一频域资源，该第一频域资源可以为频域子带，根据接收到的至少一个第一CORESET信息和第一频域资源确定与第一频域资源对应的至少一个第二CORESET信息。该与第一时域资源或与第一频域资源对应的至少一个第二CORESET信息，用于进行终端的物理下行控制信道PDCCH的检测，从而适应低带宽能力的终端接入网络，支持终端的窄带传输，其中，窄带是相对于宽带而言的，可为正常宽带中所包括的子宽带。
步骤S106，终端根据至少一个第二CORESET信息，接收物理下行控制信道PDCCH。
在本发明上述步骤S106提供的技术方案中，在终端确定第一资源对应的至少一个第二CORESET信息之后，终端根据至少一个第二CORESET信息，接收物理下行控制信道PDCCH，比如，终端根据至少一个第二CORESET信息在相应的时频资源上检测PDCCH。
在该实施例中，PDCCH用于携带下行控制信令(Downlink control information，简称为DCI)信息，终端通过PDCCH接收该DCI信息。根据携带的DCI的格式的不同，终端可以接收不同的DCI信息，以实现不同的控制，比如，该DCI信息包括下行调度信息、上行调度信息、时隙格式指示信息等。
通过本申请上述步骤S102至步骤S106，适应低带宽能力的终端接入网络，实现了改善物理下行控制信道PDCCH的接收性能的技术效果，进而解决了无法改善物理下行控制信道PDCCH的接收性能的技术问题。
下面对该实施例的上述方法进行进一步介绍。作为一种可选地实施方式，至少一个第一CORESET信息属于相同的带宽部分BWP，和/或，至少一个第二CORESET信息属于相同的BWP。
在该实施例中，至少一个第一CORESET信息属于相同的带宽部分(Bandwidth Part，简称为BWP)，也即，每个BWP可以配置至少一个第一CORESET信息，不同的第一CORESET信息之间可以进行调频；可选地，至少一个第二CORESET信息属于相同的BWP，也即，每个BWP可以配置至少一个第二CORESET信息。
该实施例的上述BWP为在载波带宽内连续的资源块的集合，该BWP的设计是为了避免终端总是在整个载波带宽内工作，尤其是对于那些低带宽能力的终端，其支持的带宽有限，无法在宽带上工作，因而BWP的引入可以是低带宽能力的终端支持更加灵活的工作带宽，减少终端的复杂度和功耗。可选地，该实施例的网络设备可以给连接态的终端配置最多4个上行BWP以及至多4个下行BWP。一个终端可以在一个时刻最多只能有一个激活的下行BWP和一个激活的上行BWP。激活的BWP可以用于使终端在该BWP上进行数据传输。激活的BWP可以在不同的BWP之间进行切换。在每个下 行BWP上，每个终端可以最多配置3个COREST和最多10个search space。
在相关技术中，每个BWP最多配置3个CORESET信息，仅用于search space的配置信息中关联最多3个CORESET信息中的一个，CORESET信息是固定的。而在该实施例中，每个BWP配置中包含的多个第一CORESET信息，用于配置该BWP的频域范围内的多个第一CORESET信息的位置，通过该多个第一CORESET信息确定第一资源对应的至少一个第二CORESET信息，也即，CORESET信息是可以进行切换的，从而支持终端的窄带传输。
作为一种可选地实施方式，第一资源包括第一时域资源，在终端根据至少一个第一CORESET信息和第一时域资源确定第一时域资源对应的至少一个第二CORESET信息的情况下，至少一个第一CORESET信息中的至少一个第一CORESET信息与至少一个第二CORESET信息中的至少一个第二CORESET信息不同。
在该实施例中，在至少一个第一CORESET信息属于相同的带宽部分BWP，和/或，至少一个第二CORESET信息属于相同的BWP的情况下，终端根据至少一个第一CORESET信息和第一时域资源确定第一时域资源对应的至少一个第二CORESET信息，可以是至少一个第一CORESET信息通过第一时域资源的变化而得到的与变化后的第一时域资源对应的至少一个第二CORESET信息，至少一个第一CORESET信息中的至少一个第一CORESET信息与至少一个第二CORESET信息中的至少一个第二CORESET信息不同，也即，至少一个第一CORESET信息可以随时间的变化而发生变化，第一CORESET信息根据第一时域资源得到第二CORESET信息，该第二CORESET信息与第一CORESET信息不同。
作为一种可选地实施方式，步骤S102，终端接收至少一个第一控制资源集合CORESET信息，包括：终端通过BWP的配置信息获得至少一个第一CORESET信息。
在该实施例中，终端通过BWP的配置信息获得至少一个第一CORESET信息，也即，每个BWP的配置信息中可以配置至少一个第一CORESET信息，至少一个第一CORESET信息在不同的时刻处于有效状态或激活状态，以达到终端根据至少一个第一CORESET信息和第一时域资源确定第一时域资源对应的至少一个第二CORESET信息的目的，该至少一个第二CORESET信息是有效的，进而根据有效的至少一个第二CORESET信息进行PDCCH的检测。
图2是根据本发明实施例的一种通过BWP的配置信息确定CORESET信息的示意图。如图2所示，在相同的一个BWP配置中，配置9个CORESET信息，将该9个CORESET信息分为三组CORESET信息，每组包含了3个CORESET信息，分别为第一组(CORESET 1，CORESET 2，CORESET 3)，第二组(CORESET 1a，CORESET 2a，CORESET 3a)，第三组(CORESET 1b，CORESET 2b，CORESET 3b)，该三组CORESET信息可以进行切换。
该实施例的不同组的CORESET信息在不同的第一时域资源有效，该第一时域资源可以为时刻，比如，第一组在T1时刻有效，第二组在T2时刻有效，第三组在T3时刻有效，它们之间的关系可以是频域上进行平移的关系，但也可以有其它的关系，比如，时频域资源都发生变化的关系。在一个确定的时刻，仅有一组CORESET信息是有效的，比如，当配置给终端设备的search space中包含的第一CORESET信息为CORESET 1时，则终端根据CORESET 1和第一时域资源，确定第一时域资源 对应的一个第二CORESET信息为CORESET 1a或CORESET 1b，也即，将CORESET 1切换为CORESET 1a或CORESET 1b。
可选地，该实施例的三组CORESET信息进行切换，可以是按照预定义的规则切换，比如，根据终端与服务器预先约定好的规则进行切换，还可以是根据信令指示切换，比如，终端接收网络设备发送的指示信息以指示CORESET信息的切换。
需要说明的是，该实施例的上述BWP可以为公共BWP，也可以为终端特定BWP。
该实施例通过在相同的一个BWP上配置多个CORESET信息，不同的CORESET信息在不同的第一时域资源有效，从而实现终端根据至少一个第一CORESET信息和第一时域资源确定第一时域资源对应的至少一个第二CORESET信息的目的，从而适应了终端的窄带操作，可以支持PDCCH在不同的频域窄带进行跳频，进而达到了改善PDCCH的接收性能的效果。
作为一种可选地实施方式，至少一个第一CORESET信息和至少一个第二CORESET信息属于相同搜索空间search space。
在相关技术中，每个search space仅配置一个CORESET信息，而在该实施例中，至少一个第一CORESET信息和至少一个第二CORESET信息可以属于相同的搜索空间search space，也即，该实施例的多个CORESET信息可以在同一search space内进行切换，每个search space可以配置多个CORESET信息，用于配置该search space对应的多个CORESET位置。
可选地，该实施例的search space的信令可以如下：
SearchSpace::＝SEQUENCE{
searchSpaceId SearchSpaceId,
controlResourceSetToAddModList SEQUENCE(SIZE(1..3))OF ControlResourceSet，
controlResourceSetToReleaseList SEQUENCE(SIZE(1..3))OF ControlResourceSetId}
该实施例的每个search space配置一个CORESET信息表(list)，该CORESET信息表包括多个CORESET信息，比如，每个search space关联的CORESET信息表中包括3个CORESET信息，在不同的时刻，该多个CORESET信息中的一个CORESET信息是有效的。
作为一种可选地实施方式，第一资源包括第一时域资源，在步骤S104，终端根据至少一个第一CORESET信息和第一时域资源，确定第一时域资源对应的至少一个第二CORESET信息的情况下，第一时域资源为search space所包含的PDCCH监听时域资源信息，至少一个第一CORESET信息中的至少一个第一CORESET信息与至少一个第二CORESET信息中的至少一个第二CORESET信息不同。
在该实施例中，终端根据同一search space中的至少一个第一CORESET信息和第一时域资源，确定第一时域资源对应的至少一个第二CORESET信息，也即，同一search space中的多个CORESET信息可以进行切换，此时的第一时域资源可以为search space所包含的PDCCH监听时域资源信息，该PDCCH监听时域资源信息可以为PDCCH监听时机，终端在监听时机根据有效的至少一个第二CORESET信息检测PDCCH，其中，对于一个终端而言，当网络设备配置了search space，则会在search  space中配置上述PDCCH监听时机。
在该实施例中，在同一搜索空间中，至少一个第一CORESET信息中的至少一个第一CORESET信息与至少一个第二CORESET信息中的至少一个第二CORESET信息不同，至少一个第一CORESET信息可以随时间的变化而发生变化，第一CORESET信息根据第一时域资源得到第二CORESET信息，该第二CORESET信息与第一CORESET信息不同。
在该实施例中，同一search space中的不同的CORESET信息在不同的第一时域资源有效，同一search space中的多个CORESET信息可以进行切换，以支持低带宽能力的终端接入网络。
作为一种可选地实施方式，终端接收至少一个第一控制资源集合CORESET信息，包括：终端通过search space的配置信息获得至少一个第一CORESET信息。
在该实施例中，可以通过search space的配置信息来获得至少一个第一CORESET信息，其中，search space的配置信息可以为search space配置的PDCCH监听时机对应的时隙，不同的监听时机对应不同的第一CORESET信息。
图3是根据本发明实施例的一种通过search space的配置信息确定CORESET信息的示意图。如图3所示，在同一search space中，T1、T2、T3为search space配置的PDCCH监听时机对应的时隙，终端在T1确定CORESET 1，在T2确定CORESET 2，在T3确定CORESET 3，该CORESET 1、CORESET 2和CORESET 3为有效CORESET，终端根据有效的CORESET检测PDCCH。
可选地，在该实施例中，同一search space中有效的CORESET信息的确定可以根据预定义的规则进行CORESET信息切换，比如，根据终端与服务器预先约定的规则进行CORESET信息；终端还可以接收网络设备发送的指示信令，可以根据指示信息实现CORESET信息的切换。该实施例通过在一个search space上配置多个CORESET信息，而不同的CORESET信息在不同的第一时域资源有效，从而实现CORESET信息的切换，适应UE的窄带操作，支持PDCCH在不同的频域窄带进行跳频，进而实现了改善物理下行控制信道PDCCH的接收性能的技术效果。
作为一种可选地实施方式，第一资源包括第一频域子带和第二频域子带，至少一个第一CORESET信息对应第一频域子带，至少一个第二CORESET信息对应第二频域子带，第一频域子带和第二频域子带属于相同或者不同的BWP。
在长期演进机对机通信(LTE MTC)技术中，为了适应低带宽能力的终端的传输，将载波带宽按照预定义的规则划分为多个频域子带，该频域子带也称为窄带(narrowband)，每个窄带包含连续的6个PRB，每个窄带有一个编号。在PDSCH和物理上行共享信道(Physical Uplink Shared Channel，简称为PUSCH)传输的调度中，在DCI中指示PDSCH和PUSCH的接收和发送的窄带的编号。然而，在该实施例中，网络针对每个BWP或者载波带宽上配置的CORESET信息，与BWP或者载波带宽上的频域子带有对应关系，每个频域子带上对应一个配置的CORESET信息。终端根据至少一个第一CORESET信息和第一频域资源确定第一频域资源对应的至少一个第二CORESET信息，其中，第一频域资源可以为至少一个第一CORESET信息对应第一频域子带(narrowband)，也即，该至少一个第一CORESET信息与第一频域子带具有对应关系。可选地，该实施例得到的至少一个第二CORESET信息与第二频域子带具有对应关系，从而CORESET信息的切换可以随不同的频域子带进行切换，也 即，根据CORESET信息与频域子带之间的对应关系，通过确定频域子带来确定CORESET信息，其中，不同的频域子带可以属于相同的BWP，也可以属于不同的BWP。
图4是根据本发明实施例的一种CORESET信息与频域子带之间的对应关系的示意图。如图4所示，BWP的配置中包含3个CORESET信息，也即，CORESET 1、CORESET 2和CORESET 3。该BWP按照预定义的规则划分为3个频域子带，即narrowband 1、narrowband 2、narrowband 3。根据CORESET信息与频域子带之间的对应关系，CORESET 1对应narrowband 1，CORESET 2对应narrowband 2，CORESET 3对应narrowband 3。可选地，当PDCCH相关的频域子带发生切换时，相应的CORESET信息也对应的发生切换。
作为一种可选地实施方式，至少一个第一CORESET信息中的至少一个第一CORESET信息与至少一个第二CORESET信息中的至少一个第二CORESET信息不同。
在该实施例中，在CORESET信息的切换可以随不同的频域子带进行切换时，至少一个第一CORESET信息中的至少一个第一CORESET信息与至少一个第二CORESET信息中的至少一个第二CORESET信息不同，至少一个第一CORESET信息可以随时间的变化而发生变化，第一CORESET信息根据第一时域资源得到第二CORESET信息，该第二CORESET信息与第一CORESET信息不同。
作为一种可选地实施方式，至少一个第一CORESET信息中的至少一个第一CORESET信息在第一频域子带上的相对时域资源或相对频域资源与至少一个第二CORESET信息中的至少一个第二CORESET信息在第二频域子带上的相对时域资源或相对频域资源相同。
在该实施例中，至少一个第一CORESET信息中的至少一个第一CORESET信息在第一频域子带上的相对时域资源或相对频域资源可以是固定的，在将至少一个第一CORESET信息中的至少一个第一CORESET信息切换为至少一个第二CORESET信息时，可以使得至少一个第二CORESET信息中的至少一个第二CORESET信息在第二频域子带上的相对时域资源或相对频域资源，与至少一个第一CORESET信息中的至少一个第一CORESET信息在第一频域子带上的相对时域资源或相对频域资源相同，以适应低带宽能力的终端的窄带传输。
可选地，在该实施例中，网络设备还可以针对每个BWP只配置一个CORESET信息，该CORESET信息的物理资源块(Physical Resource Block，简称为PRB)的位置为在一个频域子带内的相对频域位置，如果一个频域子带包括N个PRB，则CORESET信息的PRB位置可以是在一个频域子带中的N个PRB的相对频域位置。当频域子带发生切换时，根据CORESET信息在频域子带内的相对频域位置，确定对应的CORESET信息的频域资源。其中，CORESET信息的频域资源在频域子带内的相对频域位置是固定的。
作为一种可选地实施方式，终端通过指示信息或者预定义的规则确定第一频域子带或第二频域子带。
在该实施例中，终端可以获取网络设备下发的指示信息，通过该指示信息确定与至少一个第一CORESET信息对应第一频域子带，或至少一个第二CORESET信息对应第二频域子带；还可以是终端根据与服务器预先约定好的规则来确定上述第一频域子带或上述第二频域子带。
该实施例通过定义CORESET信息与频域子带之间的对应关系，可以根据频域子带的切换来确定 对应的CORESET信息，从而相比至少一个第一CORESET信息属于相同的带宽部分BWP，和/或，至少一个第二CORESET信息属于相同的BWP，以及至少一个第一CORESET信息和至少一个第二CORESET信息属于相同搜索空间search space的方案，避免了CORESET信息的单独切换的控制，降低了复杂度，同时适应了低带宽能力的终端的窄带操作，可以支持PDCCH在不同的频域子带内进行切换，congress改善了PDCCH的接收性能。
作为一种可选地实施方式，至少一个第一CORESET信息属于第一search space，至少一个第二CORESET信息属于第二search space。
在该实施例中，第一search space的配置信息中可以包括至少一个第一CORESET信息，第二search space的配置信息中可以包括至少一个第二CORESET信息，其中，第一search space与第二search space可以不相同，也可以相同，正如上述已经介绍的至少一个第一CORESET信息和至少一个第二CORESET信息可以属于相同搜索空间search space。
在该实施例中，终端可以根据网络设备所指示的搜索空间在相应的时频资源上对PDCCH进行检测，第一search space或第二search space的配置信息可以包含如下信息：search space ID；controlResourceSetId，用于指示control resource set的配置的ID，配置PDCCH search space的时频资源；监听的slot的周期以及在周期内的偏移，周期可以包括1、2、4、5、8、10、16、20、40、80、160、320、640、1280、2560个slot。Duration用于指示在PDCCH search space周期内连续监听的slot个数；monitoringSymbolsWithinSlot用于指示在PDCCH监听的slot内哪些符号上进行PDCCH监听；PDCCH candidates用于指示PDCCH candidate的配置信息。
作为一种可选地实施方式，第一search space为公共search space或者终端特定search space，第二search space为公共search space或者终端特定search space。
在该实施例中，第一search space的类型可以为公共(common)search space或者终端特定(UE-specific)Search space的类型，第二search space的类型可以为公共search space或者终端特定search space
需要说明的是，该实施例的上述方法同样适用于公共CORESET信息。对于PDCCH的公共配置信息，包括了若干公共CORESET信息和search space的配置，如下所示，包括接收SIB1、其它系统信息(Other System Information，简称为OSI)、寻呼消息(paging)和随机接入响应(Random Access Response，简称为RAR)的search space：controlResourceSetZero ControlResourceSetZero；commonControlResourceSet ControlResourceSet；searchSpaceZero SearchSpaceZero；commonSearchSpaceList SEQUENCE(SIZE(1..4))OF SearchSpace；searchSpaceSIB1SearchSpaceId
searchSpaceOtherSystemInformation SearchSpaceId；pagingSearchSpace SearchSpaceId；ra-SearchSpace SearchSpaceId。
可选地，该实施例还配置了初始(initial)BWP，用于初始接入和空闲(idle)状态下的终端的接收和发送公共信道，可以如下所示：
DownlinkConfigCommon::＝SEQUENCE{
frequencyInfoDL FrequencyInfoDL OPTIONAL,--Cond InterFreqHOAndServCellAdd
initialDownlinkBWP BWP-DownlinkCommon OPTIONAL,--Cond ServCellAdd
...
}
UplinkConfigCommon::＝SEQUENCE{
frequencyInfoUL FrequencyInfoUL OPTIONAL,--Cond InterFreqHOAndServCellAdd
initialUplinkBWP BWP-UplinkCommon OPTIONAL,--Cond ServCellAdd
dummy TimeAlignmentTimer
}
相应地，该实施例对于由网络设备配置的initial BWP、common search space、终端特定search space同样可以适用上述的终端根据至少一个第一CORESET信息和第一资源，确定第一资源对应的至少一个第二CORESET信息。
进一步地，对于至少一个第一CORESET信息对应第一频域子带，至少一个第二CORESET信息对应第二频域子带，第一频域子带和第二频域子带属于相同或者不同的BWP的方案，由于initial BWP本身的带宽可能比较窄，可以通过配置多个initial BWP，通过initial BWP的切换，对应的进行CORESET信息的切换；可以是在initial BWP中划分若干个频域子带，根据CORESET信息与频域子带之间的对应关系，通过确定频域子带来确定CORESET信息。
在相关技术中，CORESET信息的使用如图5所示，其中，图5为根据相关技术中的一种CORESET信息与BWP之间的关系的示意图，在一个小区的带宽CBW(cell bandwidth)下，可以包含若干个带宽部分BWP，不同于本申请的CORESET信息可以进行切换的是，每个BWP可以配置固定的多个CORESET信息。
在RRC信令中给出了CORESET信息的具体配置，可以如下：

ControlResourceSet::＝SEQUENCE{

}
--TAG-CONTROLRESOURCESET-STOP
--ASN1STOP
其中，主要的信息域的含义可以如下：ControlResourceSetId，用于表示CORESET的编号，取值从1～11，CORESET 0用于表示广播消息中指示的CORESET；frequencyDomainResources，用于表示CORESET频域资源，指示CORESET包含的资源块(RB)；duration，用于表示CORESET连续符号数，取值范围在{1,2,3}；cce-REG-MappingType，可以配置为交织映射或非交织映射方式；precoderGranularity，用于指示DMRS的预编码粒度是宽带预编码还是窄带预编码。但是，上述对于PDCCH的search space的配置中，CORESET信息的配置没有考虑低带宽能力的终端的所支持的窄带。另外，在LTE MTC系统中，为了减少终端的接收带宽以及减少成本和复杂度，引入了下行物理信道MPDCCH(MTC PDCCH)，承载下行物理信道MPDCCH的资源在频域上最大包含6个PRB。同时，在减少承载MPDCCH的频域带宽之后，为了提高控制信道的传输可靠性和覆盖，MPDCCH的传输引入了跳频和重复。其中，跳频可以通过频率分集来改善传输性能，重复可以使终端合并MPDCCH的多次传输，从而提高PDCCH的接收性能。
MPDCCH与LTE中的增强下行物理控制信道(Enhanced Physical Downlink Control Channel，简称为EPDCCH)非常类似，其占据的资源与物理下行共享信道PDSCH是频分复用的。如图6所示，其中，图6是根据相关技术中的一种对于PDCCH调度的PDSCH的示意图，其中，PDCCH可以在控制区域，在子帧的前几个符号。图7是根据本发明实施例的一种MPDCCH支持在多个子帧进行重复的示意图，如图7所示，不同子帧的下行物理信道MPDCCH可以跳频，也即，不同子帧的MPDCCH处于不同的频域子带。MPDCCH和其调度的PDSCH可以不在相同的频域子带内，MPDCCH中承载的DCI可以指示PDSCH所在的频域子带。
目前5G的频点分为两部分：FR1(f<6GHz，低频)和FR2(f>6GHz，高频、毫米波)。其中， FR1的带宽可以是5MHz，10MHz，15MHz，20MHz，25MHz，30MHz，40MHz，50MHz，60MHz，80MHz和100MHz；FR2的带宽可以是50MHz，100MHz，200MHz和400MHz等。为了使终端能够支持在5G频段上接入网络，对于FR1来说，终端的带宽需要支持100MHz。相应地，对于FR2的频段，终端的带宽需要支持400MHz。
在新无线系统(New Radio，简称为NR)中，希望引入上述类似的技术用于使用NR技术更好地支持除增强移动宽(Enhanced Mobile Broadband，简称为eMBB)业务之外的其他业务类型。对于新无线轻系统(NR-light)来说，支持低带宽能力的终端可以减少功耗、降低成本，而现有的NR系统并没有专门考虑支持低带宽能力的终端接入网络，比如，对于PDCCH的search space的配置中，CORESET信息的配置没有考虑低带宽能力的终端的所支持的窄带，从而无法支持PDCCH的资源的跳频和重复，无法改善物理下行控制信道PDCCH的接收性能。
而在该实施例中，通过至少一个第一CORESET信息属于相同的带宽部分BWP，和/或，至少一个第二CORESET信息属于相同的BWP、至少一个第一CORESET信息和至少一个第二CORESET信息属于相同搜索空间search space、至少一个第一CORESET信息对应第一频域子带，至少一个第二CORESET信息对应第二频域子带，第一频域子带和第二频域子带属于相同或者不同的BWP，可以实现CORESET信息的切换，进而终端根据至少一个第二CORESET信息，接收物理下行控制信道PDCCH，从而适应低带宽能力的终端的窄带操作，支持PDCCH的传输适应不同的频域窄带，达到了改善PDCCH的接收性能的目的。
下面从网络侧对本发明实施例的控制信道的确定方法进行介绍。需要说明的是，该实施例的网络侧的控制信道的确定方法与上述终端侧的控制信道的确定方法是相对应的。图8是根据本发明实施例的另一种控制信道的确定方法的流程图。如图8所示，该方法可以包括以下步骤：

作为一种可选地实施方式，至少一个第一CORESET信息和至少一个第二CORESET信息属于相同搜索空间search space。作为一种可选地实施方式，第一资源包括第一时域资源，在至少一个第一CORESET信息和第一时域资源用于使终端确定第一时域资源对应的至少一个第二CORESET信息的情况下，第一时域资源为search space所包含的PDCCH监听时域资源信息，至少一个第一CORESET 信息中的至少一个第一CORESET信息与至少一个第二CORESET信息中的至少一个第二CORESET信息不同。作为一种可选地实施方式，步骤S804，网络设备发送至少一个第一控制资源集合CORESET信息，包括：网络设备通过search space的配置信息发送至少一个第一CORESET信息。
作为一种可选地实施方式，第一资源包括第一频域子带和第二频域子带，至少一个第一CORESET信息对应第一频域子带，至少一个第二CORESET信息对应第二频域子带，第一频域子带和第二频域子带属于相同或者不同的BWP。作为一种可选地实施方式，至少一个第一CORESET信息中的至少一个第一CORESET信息与至少一个第二CORESET信息中的至少一个第二CORESET信息不同。作为一种可选地实施方式，至少一个第一CORESET信息中的至少一个第一CORESET信息在第一频域子带上的相对时域资源或相对频域资源与至少一个第二CORESET信息中的至少一个第二CORESET信息在第二频域子带上的相对时域资源或相对频域资源相同。作为一种可选地实施方式，网络设备发送指示信息，其中，指示信息用于使终端确定第一频域子带或第二频域子带。作为一种可选地实施方式，第一频域子带或第二频域子带由终端通过预定义的规则确定。

通过以上描述，本领域的技术人员可以清楚了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明各个实施例所述的方法。
本发明实施例还提供了一种新无线系统。需要说明的是，该实施例的新无线系统可以用于执行图1或图2所示的控制信道的确定方法。图9是根据本发明实施例的一种新无线系统的示意图。如图9所示，该新无线系统90可以包括：网络设备91和终端92。
网络设备91，用于发送至少一个第一控制资源集合CORESET信息；终端92，用于接收至少一个第一控制资源集合CORESET信息，根据至少一个第一CORESET信息和第一资源，确定第一资源对应的至少一个第二CORESET信息；网络设备91发送物理下行控制信道PDCCH，终端92根据至少一个第二CORESET信息，接收物理下行控制信道PDCCH。
在该实施例中，NR系统主要是为了支持eMBB业务而设计的，其主要技术是为了满足高速率、高频谱效率、大带宽的需要。实际上，除了eMBB业务，还存在多种不同的业务类型，比如，传感器网络、视频监控、可穿戴等，它们在速率、带宽、功耗、成本等方面与eMBB业务有着不同的需求。支持这些业务的终端相比支持eMBB业务的终端的能力是降低的，比如，支持的带宽减小、处理时间放松、天线数减少等。需要针对这些业务和相应的低带宽能力对NR系统进行优化，这样的系统称为NR-light系统。而在LTE技术中，已经有了类似的系统设计用于支持大连接数、低功耗、低成本的终端，比如，MTC，基于蜂窝的窄带物联网NB-IoT(Narrow Band Internet of Things，简称为NB-IoT)。在NR系统中，希望引入类似的技术用于使用NR技术更好地支持除eMBB业务之外的其他业务类型。而该实施例的新无线系统通过终端根据从网络设备接受到的至少一个第一CORESET信息和第一资 源，确定第一资源对应的至少一个第二CORESET信息，进而终端根据至少一个第二CORESET信息，接收物理下行控制信道PDCCH，从而适应低带宽能力的终端接入网络，可以支持PDCCH的资源的跳频和重复，实现了改善物理下行控制信道PDCCH的接收性能的技术效果，进而解决了无法改善物理下行控制信道PDCCH的接收性能的技术问题。
