背景技术
在新空口(new radio，NR)系统中，将物理下行控制信道(physical downlink control channel，PDCCH)频域上占据的频段和时域上占用的正交频分复用(orthogonal frequency division multiplexing，OFDM)符号数等信息封装在控制资源集(control-resource set，CORESET)中；将PDCCH起始OFDM符号编号以及PDCCH监测周期等信息封装在搜索空间(search space)中。每个搜索空间关联一个CORESET，通过一个CORESET和一个搜索空间绑定起来后可以确定PDCCH的配置。
NR系统中，网络设备通过无线资源控制(radio resource control，RRC)给终端设备配置CORESET。网络设备通过RRC配置CORESET时，是对每个终端设备单独通知的。如果网络设备通知多个终端设备修改CORESET占用的时频资源，通过RRC指示的方式需要较长时间，使得CORESET调整无法实时跟踪业务变化需求，影响用户体验。

具体实施方式
为便于理解本申请实施例，下面首先结合本申请中涉及的几个术语进行简单介绍。
1、CORESET：终端设备在接收PDCCH时，需要知道PDCCH在频域上的位置和时域上的位置。目前，可以将PDCCH频域上占据的频段和时域上占用的OFDM符号数等信息封装在CORESET中；将PDCCH起始OFDM符号编号以及PDCCH监测周期等信息封装在搜索空间中。每个搜索空间关联一个CORESET，通过一个CORESET和一个搜索空间可以确定PDCCH的配置。
CORESET在时域上通常占用{1,2,3}个符号数，起始位置可以是一个时隙的任意位置CORESET在频域上为6个资源块(resource block，RB)的整数倍。
2、资源单元组(resource element group，REG)：一个REG由频域上的1个RB，时域上的一个OFDM符号组成。一个CORESET内的REG编号按照时域优先顺序递增，第一个OFDM符号且最低频域资源的RB为REG0，如图1所示。
3、控制信道元素(control channel element，CCE)：一个CCE对应6个REG。PDCCH可能占用的资源以及PDCCH实际占用的资源都可以用CCE描述。
4、聚合级别：PDCCH使用的CCE的数量可以成为聚合级别，例如NR系统中定义了PDCCH可以使用{1,2,4,8,16}个CCE，其中使用的CCE个数又称为聚合级别。搜索空间给出了终端设备需要监测的PDCCH候选的聚合级别，以及该聚合级别对应的PDCCH候选数量。如图2所示，一个包含32个CCE的CORESET，可以定义CCE聚合级别为1的搜索空间，CCE聚合级别为2的搜索空间，CCE聚合级别为4的搜索空间，CCE聚合级别为8的搜索空间，CCE聚合级别为16的搜索空间。
5、REG簇(REG bundle)：一个REG簇包括L个REG，通过一个或者多个REG簇可以实现CCE到REG的映射。CCE到REG的映射支持交织和非交织两种方式，具体的映射规则如下：
1)编号为i的REG簇是由编号为{iL,iL+1,…，iL+L-1}的REG组成，

2)编号为j的CCE是由编号为

的REG簇组成，其中f(·)是交织器。
对于非交织的CCE到REG的映射，L＝6，且f(x)＝x。
对于交织的CCE到REG的映射，如果CORESET符号数

前文介绍了本申请实施例所涉及到的一些名词概念，下面介绍本申请实施例涉及的技术特征。
目前，NR通过RRC给终端设备配置CORESET，通知终端设备检测的PDCCH占用的时频资源。NR通过RRC配置CORESET时，是对每个终端设备单独通知的。在网络设备通过RRC通知多个终端设备修改CORESET占用的时频资源，需要较长时间，从而无法实时跟踪业务变化需求，影响用户体验。
此外，如果CORESET 0与终端设备随机接入后被配置的其他CORESET(假设为CORESET 1)等在资源上重叠，CORESET 1采用交织的方式的情况下与CORESET0冲突的CCE，要多于，CORESET 1采用非交织的方式的情况下与CORESET0冲突的CCE。假设系统带宽为100M，包括273个RB，CORESET1为1符号，270个REG，45个CCE，REG簇大小L＝2，交织深度R＝3，CORESET0占用24个RB时，非交织的CORESET1和交织的CORESET1分别与CORESET0冲突的CCE情况如图3所示。可以看出非交织CORESET1冲突了4个CCE，而交织的CORESET1冲突了12个CCE。其中，图3中只给出了CORESET1中与CORESET0冲突区域的CCE情况，其他部分的CCE并没有给出。 因此，交织的CORESET与CORESET 0资源冲突时可用资源较少。
基于此，本申请实施例提供两种通信方法及装置，用于解决网络设备通知终端设备修改CORESET占用的时频资源时花费的时间太长的问题，以及交织的CORESET与CORESET 0资源冲突时可用资源较少的问题。其中，方法和装置是基于同一发明构思的，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
本申请实施例的技术方案可以应用于各种通信系统，例如：可以是物联网(internet of things，IoT)、窄带物联网(narrow band internet of things，NB-IoT)、LTE，也可以是第五代(5 th generation,5G)通信系统，还可以是LTE与5G混合架构，也可以是6G或者未来通信发展中出现的新的通信系统等。本申请所述的5G通信系统可以包括非独立组网(non-standalone，NSA)的5G通信系统、独立组网(standalone，SA)的5G通信系统中的至少一种。通信系统还可以是M2M网络、MTC或者其他网络。
如图4所示，本申请实施例提供的通信方法可应用于通信系统，该通信系统包括网络设备和六个终端设备，即UE1～UE6。在该通信系统中，UE1～UE6可以发送上行信息给网络设备，网络设备可以接收UE1～UE6发送的上行数据。此外，UE4～UE6也可以组成一个子通信系统。网络设备可以发送下行信息给UE1、UE2、UE3、UE5，UE5可以基于设备到设备(device-to-device，D2D)技术发送下行信息给UE4、UE6，或者UE4～UE6之间可以基于设备到设备(device-to-device，D2D)技术相互之间进行通信。
本申请实施例也可用于其他通信系统，只要该通信系统中需要进行跨时隙的上行传输。另外申请实施例不仅适用于一个网络设备和一个UE通信的场景，而且适用于一个网络设备与多个UE通信，或者，多个网络设备协作同时与一个或多个UE进行通信的场景。图4仅是一种示意图，并不对通信系统的类型，以及通信系统内包括的设备的数量、类型等进行具体限定。
本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题同样适用。
本申请实施例中“在……情况下”，也可以描述为“若……”或者“如果”或者“当……时”等等。例如，“在第二CORESET的符号数为1的情况下”，也可以描述为“若第二CORESET的符号数为1”，或者“如果第二CORESET的符号数为1”或者“当第二CORESET的符号数为1时”等等。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。应理解的是，本申请实施例中示出的单个执行主体(终端设备或网络设备)所执行的处理也可以被划分为由多个执行主体执行，这些执行主体可以在逻辑上和/或在物理上分离，例如，当网络设备为CU和DU的整体时，网络设备所执行的处理可以被划分为由CU和DU执行。
针对网络设备通知终端设备修改PDCCH占用的符号数时花费的时间太长的问题，本申请提供的两种通信方法。该方法的执行主体可以是通信设备(如终端设备、网络设备)，也可以是芯片或电路。
实施例一：如图5所示，该方法包括：
S601，网络设备在第一CORESET或第二CORESET中向终端设备发送第一信令。相 应的，终端设备在第一CORESET或第二CORESET中接收来自网络设备的第一信令。
其中，第一信令用于指示第二CORESET占用的资源，例如，第一信令可以指示第二CORESET的时域资源，或者，第一信令可以指示第二CORESET的频域资源，或者，第一信令可以指示第二CORESET的时频资源。
第一信令指示第二CORESET的频域资源的实现方式可以为，第一信令可以指示第二CORESET的第一符号数。一种实现方式中，第二CORESET的可调整的候选符号数可以包括1和/或2，通过该方式，第一信令可以通过1比特进行指示，从而可以节省开销。当然，第二CORESET的可调整的候选符号数也可以包括其他，这里不做具体限定。
第一信令指示第二CORESET的频域资源的实现方式可以为，第二CORESET对应至少两个频域资源，网络设备可以通过第一信令指示第二CORESET使用的频域资源。
第一信令指示第二CORESET的时频资源的实现方式可以为，第二CORESET对应至少两个时频资源配置，其中，至少两个时频资源配置中任意两个时频资源配置的符号数不同和/或频域资源不同，网络设备可以通过第一信令指示第二CORESET使用的时频资源配置。
上述方式，通过第一信令调整第二CORESET占用的资源，有利于PDCCH的传输，提升通信可靠性，或者，有利于提升资源利用率。例如，当终端设备需要较多调度资源时，可以通过第一信令指示第二CORESET占用更多的符号数，和/或，指示第二CORESET占用更多的频域资源，有利于PDCCH的传输，从而提升通信可靠性。当终端设备需要较少调度资源时，可以通过第一信令指示第二CORESET占用更少的符号数，和/或，指示第二CORESET占用更少的频域资源，剩余的时频资源可以分配给其他传输，例如物理下行共享信道(physical downlink shared channel，PDSCH)等，有利于提升资源利用率，还可以提升用户体验。如图6所示，分别为CORESET占一个符号和占两个符号的示意图。
并且，通过第一信令指示第二CORESET的符号数，可以降低对频域分集的影响。
通过第一信令指示第二CORESET的频域资源，可以实现更小的调整粒度。
一种可能的实施方式中，第一信令还可以指示PDCCH的调制方式。例如，在信道质量好、或者调度较多的情况下，第一信令可以指示PDCCH的调制方式为16正交幅度调制(quadrature amplitude modulation，QAM)。例如，在信道质量较差、或者调度较少的情况下，第一信令可以指示PDCCH的调制方式为正交相移键控(quaternary phase shift keying，QPSK)调制。通过上述方式可以进一步提升PDCCH容量，有利于提高系统性能，提升用户体验。
在第一信令在第一CORESET中发送的实施方式中，第一信令的监测周期可以是：第一搜索空间指示的PDCCH监测周期或同步信号/物理广播信道块(synchronization signal/PBCH block，SSB)的周期，其中，第一搜索空间用于监测调度系统消息块1(system information block 1，SIB1)的PDCCH，例如，第一搜索空间为搜索空间0，第一CORESET与该SSB为相同的波束方向，或者，第一CORESET与该SSB的准共位置(quasi-colocation，QCL)关系至少可以为type-D。可选的，在上述实施方式中，第一信令可以指示一个时隙上第二CORESET占用的资源，或者，也可以指示多个时隙上第二CORESET占用的资源。例如第一信令可以指示第二CORESET在半帧或者一个帧中的各个时隙上的资源情况，第二CORESET在不同时隙上的资源可以相同也可以不同。一种实现方式中，可以通过时隙组的方式指示第二CORESET在各个时隙组上的资源，即将多个时隙进行分组，时隙组内 的时隙上的资源相同，不同时隙组上的资源可以相同也可以不同。另一个种实现方式中，可以通过单个时隙的方式指示第二CORESET在各个时隙上的资源，即每个时隙都有对应的资源指示，不同时隙上的资源可以相同也可以不同。具体的，可以采用位图(bitmap)的方式进行指示多个时隙上第二CORESET占用的资源。
或者，也可以为配置第二搜索空间，第一信令的监测周期可以由第二搜索空间指示。其中，第二搜索空间指示的周期与第一搜索空间指示的周期不一样。
一个具体的示例中，网络设备可以在多个方向发送多个第一信令，例如，网络设备可以采用多个波束发送第一信令。可选的，该多个方向可以在上述SSB的波束方向范围内。
在上述示例中，网络设备可以一次发送一个波束，也可以同时发送多个波束，这里不作具体限定。
第一信令可以是UE级的信令、UE组(group级)的信令或小区级信令。一种可能的实现方式是，第一信令是一个小区级的信令，网络设备可以在不同时刻在多个波束发送多个第一信令，这多个第一信令的内容是一样的。另一种可能的实现方式是，第一信令是一个UE组级或UE级的信令，网络设备可以在不同时刻在多个波束发送多个第一信令，这多个第一信令的内容可以一样可以不一样。
示例性的，第一信令在第一CORESET中的映射方式可以采用NR中PDCCH的映射方式。或者，第一信令在第一CORESET中的映射方式也可以与第一信令在第二CORESET中的映射方式相同，例如，第一信令的映射方式可以为：第一信令包括N个子信息，每个子信息占用第二CORESET中的M个RB，且每个子信息占用RB的最小标识为p的整数倍，N为大于0的整数，例如，N可以为2，4或8等，M为p的整数倍，p为大于1的整数，例如，p可以为2，3或6。如图7所示，以N为4，p为6，M为6为例，第一信令可以映射在标识为0～5，12～17，24～29，36～41的RB上。通过该映射方式可以便于第二CORESET中剩余资源区域的REG簇重新映射。
在上述示例中，第一信令与第二CORESET的符号数可以不同，通过该设计，可以提升第一信令的灵活性。当然，第一信令与第二CORESET的符号数也可以相同，这里不做具体限定。
本申请实施例中，第一CORESET可以是公共CORESET，第二CORESET可以是终端设备专属CORESET。或者，第一CORESET的标识为0，即第一CORESET为CORESET 0，第二CORESET的标识大于0，即第二CORESET可以为CORESET 1、CORESET 2、CORESET 3等等。或者，第二CORESET也可以是由终端设备专属信令配置的CORESET，第一CORESET是物理广播信道(physical broadcast channel，PBCH)或系统信息配置的CORESET。或者，第一CORESET可以用于在空闲态监测物理下行控制信道，第二CORESET用于在非空闲态监测物理下行控制信道。或者，第一CORESET可以是在终端设备初始接入之前配置的，第二CORESET可以是在终端设备初始接入之后配置的。或者，第一CORESET可以是时频资源大小不能通过第一信令指示快速改变的CORESET，第二CORESET可以是时频资源大小可以通过第一信令指示快速改变的CORESET。或者，第一CORESET和第二CORESET中的至少一个是通过网络设备通过信令指示的。
可选的，网络设备可以通过第一信令指示终端设备的多个小区的第二CORESET的资源，例如，网络设备可以在主小区(primary cell，PCell)和/或特殊小区(special cell，SpCell)中发送第一信令。相应的，终端设备可以在PCell和/或SpCell中检测第一信令。通过该方 式，可以使得终端设备的其他小区不用分出资源监测第一信令，对其他小区影响较小。
S602，网络设备根据第一符号数调整第二CORESET。
需要说明的是，S601和S602在执行上没有严格的先后顺序，这里不做具体限定。
其中，网络设备和终端设备调整第二CORESET的方式类似，具体调整方式将在下文详细说明。
S603，终端设备根据第一信令调整第二CORESET。
一种实现方式中，若第一信令指示第二CORESET的符号数为第一符号数，则可以将第二CORESET的符号数调整为第一符号数。若第一信令指示第二CORESET的频域资源，则可以将第二CORESET的频域资源调整为第一信令指示的频域资源，例如，调整为第一信令指示的频域资源大小和/或频域位置等等。若第一信令指示第二CORESET的时频资源，则可以将第二CORESET的时频资源调整为第一信令指示的时频资源，例如，在时域上可以调整为第一信令指示的时域大小，在频域上可以调整为第一信令指示的频域资源大小和/或频域位置。
在第一信令在第二CORESET中发送的实施方式中，可以从第一时隙开始调整第二CORESET，第一时隙为接收第一信令的时隙。或者，也可以从第一时隙的下一个时隙(下面称为第二时隙)或第一时隙所在子帧的下一个子帧(下面称为第一子帧)开始，调整第二CORESET。
需要说明的是，该从第一时隙开始调整第二CORESET的方式中，调整第二CORESET的时隙包括第一时隙，第二CORESET在第一时隙后的时隙上的资源与第一时隙上调整后的资源相同，直到接收到下一个指示第二CORESET的资源的信令。
该从第二时隙开始调整第二CORESET的方式中，调整第二CORESET的时隙包括第二时隙，第二CORESET在第二时隙后的时隙上的资源与第二时隙上调整后的资源相同，直到接收到下一个指示第二CORESET的资源的信令。
该从第一子帧开始调整第二CORESET的方式中，调整第二CORESET的时隙包括第一子帧的第一个时隙(下面称为第三时隙)，第二CORESET在第三时隙上的资源与第三时隙上调整后的资源相同，直到接收到下一个指示第二CORESET的资源的信令。
可选的，在调整第二CORESET的资源大小后，还可以将第二CORESET的REG、REG簇或CCE重新进行编号。具体的，若调整第二CORESET的时隙包括第一时隙，可以将第二CORESET的REG、REG簇或CCE重新进行编号。具体过程将在下文详细介绍。
需要说明的是，第二CORESET的资源大小的调整过程与重新编号过程可以分开执行，例如，可以调整第二CORESET的资源大小，再将第二CORESET的REG、REG簇或CCE重新进行编号。或者，第二CORESET的资源大小的调整过程与重新编号过程也可以同时执行，例如，在调整第二CORESET的资源大小时将第二CORESET的REG、REG簇或CCE重新进行编号。
本申请实施例中，通过在CORESET(如第一CORESET或第二CORESET)中发送指示CORESET的资源的信令，有利于实现CORESET资源的灵活指示，从而可以更快匹配业务需求，改善用户体验。具体的，通过在第一CORESET中检测第一信令，可以降低映射第一信令的复杂度。通过在第二CORESET中监测第一信令，有利于网络设备更灵活的配置第一信令，并且可以不占用小区级或UE组级的资源，便于其他小区级或UE组级的信令的发送。
下面结合经过调整后第二CORESET的四种情况，将第二CORESET的REG或CCE重新进行编号的过程进行介绍。应理解，下文中将第二CORESET的REG或CCE重新进行编号时，第二CORESET占用的符号数为第一信令指示的符号数，第二CORESET占用的频域资源为第一信令指示的频域资源。
情况一，第一信令在时域上占用一个符号，且第一信令指示第二CORESET的符号数为1，也就是第二CORESET在根据第一信令调整后，符号数为1。
这种情况下，第二CORESET在根据第一信令调整之前占用的符号数可以等于1也可以大于1。
在该情况下，第二CORESET重新编号的过程可以为：将第二CORESET中除第一资源以外的其他REG进行重新编号，第一资源为第一信令占用的REG。也即，在将第二CORESET的REG重新编号时可以跳过第一资源，即第一资源不参与重新编号。
一种举例说明中，结合图7所示举例，以第二CORESET在根据第一信令调整之前占用的符号数为2为例，第二CORESET重新编号的过程可以如图8所示。
情况二，第一信令在时域上占用一个符号，且第一信令指示第二CORESET占用的符号数大于1，也就是第二CORESET在根据第一信令调整后，符号数大于1。
这种情况下，第二CORESET在根据第一信令调整之前占用的符号数可以等于1也可以大于1。
该情况下，第二CORESET重新编号的过程可以为：将第二CORESET中除第二资源以外的其他REG进行编号，其中，第二资源在频域上与第一信令在频域上占用的资源相同，且第二资源在时域上与调整后的第二CORESET占用的符号相同。
一种举例说明中，结合图7所示举例，以第二CORESET在根据第一信令调整之前占用的符号数为3，且第一信令指示2个符号为例，第二CORESET重新编号的过程可以如图9所示。
或者，将第二CORESET中除第一资源以外的其他REG进行编号，其中，第一资源为第一信令占用的REG，在该方式中，若第二资源中第一资源以外的剩余REG对REG簇的长度取模时有余数m，则可以将该余数对应的REG(即m个REG)丢弃。“将该余数对应的REG丢弃”可以理解为在将第二CORESET中除第二资源以外的其他REG进行编号时跳过该部分REG，或者，该部分REG不参与重新编号。
本申请实施例中，REG簇的长度也可以称为REG的大小(size)。
情况三，第一信令在时域上占用的符号的数量与第二CORESET的符号数相同，且第一信令指示的符号数小于第一信令在时域上占用的符号的数量，也就是，第二CORESET在根据第一信令调整后的符号数小于在根据第一信令调整前的符号数。和/或，第二CORESET在根据第一信令调整后的频域资源小于在根据第一信令调整前的频域资源。
该情况下，第二CORESET重新编号的过程可以为：将第二CORESET中除第三资源以外的其他REG、REG簇或CCE进行重新编号，第三资源为第一信令占用的REG、REG簇或CCE。
可选的，其他信号(例如PDSCH)在第二CORESET调整前的资源位置进行发送时，避开第一信令所占的资源。
情况四，第一信令在时域上占用的符号的数量与第二CORESET的符号数相同，且第一信令指示的符号数大于第一信令在时域上占用的符号的数量，也就是，第二CORESET 在根据第一信令调整后的符号数大于在根据第一信令调整前的符号数。
该情况下，第二CORESET的重新编号的过程可以参阅上述情况二中第二CORESET的重新编号的过程，这里不再赘述。
上文介绍了终端设备和网络设备重新编号的过程的方式。通过上述方式，可以降低第一信令与映射在第二CORESET的PDCCH之间的冲突。
在上述方式中，第二CORESET的符号数和/或频域资源发生变化，而随着第二CORESET的符号数和/或频域资源变化，第二CORESET的资源数量改变了，旧的L和R参数可能不适用，不能保证C依然为整数，使得交织后，部分REG簇中可能没有足够的REG，或者部分REG没有映射到REG簇，其中，C可以参阅前文术语介绍中REG簇中的公式说明。针对这个问题，本申请实施例提供三种解决方法。
方法一：可以调整第二CORESET的交织行数R，和/或，REG簇的长度L，通过这种方式可以保证C为整数，从而可以提升资源利用率。
例如，可以为第二CORESET配置至少两个交织行数值，和/或，至少两个REG簇长度值。在该方式中，可以根据第一信令确定第二CORESET的交织行数R，和/或，第二CORESET的REG簇的长度L。
其中，确定的R和L可以使C为整数，也即确定的R和L可以满足：
Figure PCTCN2022112097-appb-000033
为整数。其中，若第一信令在第一CORESET中发送，
Figure PCTCN2022112097-appb-000034
为第二CORESET调整符号数后的REG数。若第一信令在第二CORESET中发送，
Figure PCTCN2022112097-appb-000035
也可以为第二CORESET调整符号数后除第一资源或者第二资源或者第三资源外剩余的REG数。
一种具体方式中，交织行数值和/或REG簇长度值可以与符号数存在对应关系。在根据第一信令确定第二CORESET的交织行数R，和/或，第二CORESET的REG簇的长度L时，可以根据第一信令指示的符号数确定对应的交织行数值和/或REG簇长度值。
另一种具体方式中，终端设备可以选择一组R和L，若该交织行数值和REG簇长度值不满足：
Figure PCTCN2022112097-appb-000036
为整数，则选择下一组R和L。若该组R和L依然不满足：
Figure PCTCN2022112097-appb-000037
为整数，则继续选择下一组R和L，直到选择出满足
Figure PCTCN2022112097-appb-000038
为整数的R和L作为第二CORESET的交织行数和/REG簇的长度。在该方式中，网络设备可以配置一组R和L为默认值，终端设备在选择R和L时，优先选择该默认值。
可选的，可以在第二CORESET的RB数量不能被12和/或18整除时，为第二CORESET配置至少两个交织行数值，和/或，至少两个REG簇长度值。由于第二CORESET的RB数不能被12或者18整除，不会存在一组R和L，使得第二CORESET在符号数变化时C一直为整数，例如，第二CORESET的RB数为30、150时，不存在一组R和L，使得第二CORESET符号数变化时，C一直为整数。又例如，第二CORESET的RB数为270时，存在一组R和L(L＝6、R＝3)，使得第二CORESET符号数变化时，C一直为整数。示例性的，如表1所示，为第二CORESET的RB数为270，在符号变化时可能的L和R取值情况。

方法二，若终端设备支持CORESET的符号数在1,2,3之间改变，L可以为6。其中，网络设备可以配置L等于6，或者，终端设备也可以默认L等于6，或者协议可以预定义L为6。该实现方式中，交织行数可以配置一个也可以配置多个，这里不做具体限定。
方法三，如果配置的L和R，计算出的C不是整数，则可以舍弃部分REG簇，使得C为整数，可以按照REG簇的标识从小到大的顺序(或者从大到小的顺序)进行舍弃。其中，“舍弃部分REG簇”可以理解为，在编号时跳过该部分REG簇，或者，该部分REG簇不参与编号，或者，第二CORESET不包括该部分REG簇。
上文提到，由于第二CORESET的符号数发生变化，第二CORESET的资源数量改变了，旧的L和R参数可能不适用。此外，由于第二CORESET的资源数量改变，旧的候选PDCCH数量也可能不适用，例如，如果第二CORESET的资源数量变大，沿用旧的候选PDCCH数量，可能导致终端设备需要监测的CCE数量超过终端设备能力。基于此，本申请实施例中，可以调整与第二CORESET关联的搜索空间中聚合等级对应的候选PDCCH数量，通过上述方式有利于更好的进行PDCCH资源分配。
一种实现方式中，可以在与第二CORESET关联的搜索空间配置：至少一个聚合等级对应的候选PDCCH数量，其中，至少一个聚合等级中第一聚合等级对应至少两个候选PDCCH数量。
另一种实现方式中，也可以在与第二CORESET关联的搜索空间配置：至少一个聚合等级对应的最大候选PDCCH数量。在该实现方式中，如果第二CORESET对应的资源数能够支持该最大候选PDCCH数量时，可以采用该最大候选PDCCH数量。如果不支持，可以采用在第一聚合等级下，该第二CORESET对应的资源支持的候选PDCCH数量的最大值，其中，第一聚合等级为与第二CORESET关联的搜索空间中配置的聚合等级。
可以理解的，上述两种实现方式也可以结合使用。
再一种实现方式中，可以以第二CORESET调整前后的符号数比例调整候选PDCCH数量。例如，如表2所示，第二CORESET占用的符号数为2，聚合等级P为1,2,4,8，对应的候选PDCCH数量分别为6,6,2,2，若第一信令指示第二CORESET的符号数为1，聚合等级P为1,2,4,8对应的候选PDCCH数量可以分别为3,3,1,1。

在一种可能的实现方式中，第一信令可以采用第一无线网络临时标识(radio network temporary identifier，RNTI)加扰，第一RNTI为第一信令对应的RNTI。通过上述实现方式可以将第一信令与其他信令进行区分，从而可以提高指示CORESET的符号数的可靠性。
可选的，本申请实施例中，第二CORESET可以采用较高的聚合等级，例如8、16等。较高的聚合等级有利于提高第一信令的可靠性。通过提高第一信令的可靠性有利于PDCCH的调度，从而可以提升通信性能。
可选的，第二CORESET不与以下搜索空间中的一个或多个关联：调度其他系统信息的PDCCH的候选组成的搜索空间，调度寻呼消息的PDCCH的候选组成的搜索空间，和/或，随机接入搜索空间，公共搜索空间。该方式有利于减少对其他不调整CORESET的终端设备或者无法接收调整CORESET信令的终端设备的影响。
实施例二，本申请实施例还提供一种调整CORESET的方式。该方法包括，网络设备可以在第一CORESET或第二CORESET中向终端设备发送第二信令，第二信令可以指示监测第二CORESET或第三CORESET，其中，第三CORESET与第二CORESET的符号数和/或频域资源不同。终端设备根据第二信令确定监测的CORESET。

一种实现方式中，终端设备在接收到下一个用于指示第二CORESET中与第一 CORESET重叠的资源是否可用的信令之前，可以根据第三信令的指示确定第二CORESET中与第一CORESET重叠的资源是否可用。
若第二CORESET中与第一CORESET重叠的资源不可用，执行S902和S903。

实施例四，本申请实施例提供的另一种通信方法包括：网络设备在第一CORESET或第二CORESET或第四CORESET中向终端设备发送第四信令。其中，第四信令还用于指示监测第二CORESET与第四CORESET中的一个，其中，第二CORESET与第一CORESET重叠，第四CORESET与第一CORESET不重叠。终端设备根据第四信令监测第二CORESET或第四CORESET。

需要说明的是，上述实施例一～实施例四可以分别作为一个独立的方案实施，也可以将实施例一和实施例二中的一个实施例，以及，实施例三和实施例四中的一个实施例，结合起来作为一个方案实施。例如，实施例一和实施例三结合起来作为一个方案实施，可以理解的，在该结合方案中，第一信令和第三信令可以为两个信令，也可以为同一个信令。又例如，实施例二和实施例四结合起来作为一个方案实施，可以理解的，在该结合方案中，第二信令和第四信令可以为两个信令，也可以为同一个信令。再例如，实施例一和实施例四结合起来作为一个方案实施，可以理解的，在该结合方案中，第一信令和第四信令可以为两个信令，也可以为同一个信令。再例如，实施例二和实施例三结合起来作为一个方案实施，可以理解的，在该结合方案中，第二信令和第三信令可以为两个信令，也可以为同一个信令。
