对于终端来说，上述在第一CORESET中进行PDCCH的传输可以是，监听PDCCH，而对于网络来说，上述在CORESET中进行PDCCH的传输可以是，发送PDCCH。所述PDCCH可以为调度PDCCH，该调度PDCCH可以包括如下至少一项：调度系统信息块(system information block，SIB)1的PDCCH，调度系统信息(SI message)的PDCCH，调度随机接入响应(Random Access Response，RAR)的PDCCH，调度上行消息3(MSG3)物理上行共享信道(Physical uplink Shared Channel，PUSCH)的PDCCH，调度消息4(MSG4)的PDCCH，调度终端专用数据(UE specific data)的PDCCH等，也可以为组公共(group common)PDCCH。
本公开实施例中，通过上述步骤可以配置两个CORESET，从而提高终端接收PDCCH的性能，终端可以及时接收到PDCCH。例如：配置新的窄带initial DL BWP，即确定新的CORESET#0资源，并进一步还可以在该窄带initial DL BWP上进行PDCCH和物理下行共享信道(Physical Downlink Shared Channel，PDSCH)传输，具体参见下面描述。
作为一种可选的实施方式，所述PDCCH为类型0(Type-0)PDCCH。
其中，上述Type-0 PDCCH可以是协议中定义的Type-0 PDCCH，且上述第二CORESET也可以用于传输Type-0 PDCCH，从而实现支持两个用于Type-0 PDCCH传输的CORESET，这样终端可以根据自己的能力在相应的CORESET进行Type-0 PDCCH的接收，以使得终端可以及时接收到Type-0PDCCH。
作为一种可选的实施方式，所述第一CORESET的资源参数为默认参数或者网络指示的资源参数；或者
所述第一CORESET的资源参数依据所述第二CORESET的资源参数确定的。
其中，上述第一CORESET的资源参数为默认参数可以是，第一CORESET的全部或者部分资源参数是默认的参数值，这样可以节约传输开销。
上述第一CORESET的资源参数为网络指示的资源参数可以是，第一CORESET的全部或者部分资源参数为网络指示的资源参数，这样可以灵活配置第一CORESET。例如：所述网络指示可以显示指示第一CORESET的资源参数，如直接指示第一CORESET的资源参数的参数值。
而上述第一CORESET的资源参数依据所述第二CORESET的资源参数确定的可以是，第一CORESET的全部或者部分资源参数依据所述第二CORESET的资源参数确定，这里的依据所述第二CORESET的资源参数确定可以是直接依据所述第二CORESET的资源参数确定，而不需要网络指示，这样可以节约传输开销。
另外，第一CORESET一部分资源参数可以是默认的，另一部分资源参数可以为网络指示或者依据所述第二CORESET的资源参数确定的。
作为一种可选的实施方式，所述第一CORESET的资源参数依据所述第 一CORESET的资源参数与所述第二CORESET的资源参数的对应关系确定，所述对应关系由网络指示。
其中，上述对应关系可以是所述第一CORESET的资源参数与所述第二CORESET的资源参数之间的比值或者偏移等。由于通过上述对应关系指示，可以节约信令开销。
作为一种可选的实施方式，所述第一CORESET的资源参数包括如下至少一项：
带宽、频率位置、起始RB、符号数量和物理下行控制信道搜索空间(PDCCH search space)。
需要说明的是，这里参数中可以是部分或者全部是默认的，或者部分或者全部是网络指示的，或者部分或者全部是依据所述第二CORESET的资源参数确定的。
以带宽为例，上述第一CORESET的带宽可以使用默认参数，例如：假设该带宽为24个RB，48个RB的默认值。或者，上述第一CORESET的带宽根据网络的指示，网络指示该第一CORESET相对于第二CORESET的大小，例如网络指示一个比例因数(scaling factor)＝1/2，则第一CORESET带宽为第二CORESET带宽的1/2。
以频率位置(RB offset)为例，上述第一CORESET的频率位置可以是默认的，例如：0,2,4,6,8等，或者根据网络的指示，如网络指示第一CORESET的RB OFFSET的具体数值，或者相对于第二CORESET的RB offset配置的大小，例如，和第二CORESET的RB offset相同，或者是第二CORESET的RB offset的1/2。
上述符号可以是正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号，以OFDM符号为例，上述第一CORESET的OFDM符号个数可以使用默认参数，假设第一CORESET的OFDM符号数为确定的值，例如：2，3，4等。或者，第一CORESET的OFDM符号个数根据网络的指示，网络指示该第一CORESET的OFDM符号数的具体数值，或者相对于第二CORESET的OFDM符号数的配置大小。
同样的，上述第一CORESET的起始RB可以是默认的，或者网络指示 的。
可选的，在所述起始RB为默认参数的情况下，所述起始RB为：
使用所述第二CORESET的起始RB进行偏移确定；或者
使用SSB的起始RB进行偏移确定；或者
依据所述第二CORESET的带宽、用于传输SSB的带宽和所述第一CORESET的带宽确定。
其中，上述使用所述第二CORESET的起始RB进行偏移确定可以是，第一CORESET的起始RB为第二CORESET的起始RB偏移一个或者多个RB。使用SSB的起始RB进行偏移确定可以是，第一CORESET的起始RB为SSB的起始RB偏移一个或者多个RB。
而上述依据所述第二CORESET的带宽、用于传输SSB的带宽和所述第一CORESET的带宽确定可以是，根据第二CORESET的带宽、用于传输SSB的带宽和所述第一CORESET的带宽之间的关系来确定CORESET的起始RB，例如：第二CORESET的带宽和所述第一CORESET的带宽相同，且第二CORESET的带宽包含SSB的带宽，则第一CORESET的起始RB可以为第二CORESET的起始RB。
可选地，所述第一CORESET的RB包括用于传输SSB的RB，和/或，所述第一CORESET的所有RB包含在所述第二CORESET的RB集合内。
需要说明的是，所述第一CORESET的RB包括用于传输SSB的RB，和，所述第一CORESET的所有RB包含在所述第二CORESET的RB集合内表示，所述第一CORESET的RB包括用于传输SSB的RB，且所述第一CORESET的所有RB包含在所述第二CORESET的RB集合内。
该实施方式中，可以实现第一CORESET的带宽能包含所有传输SSB的RB，以及可以实现第一CORESET的所有RB资源包含在第一CORESET的RB资源范围内。例如：如图4所示。
需要说明的是，该实施方式中可以与上述确定起始RB的实施方式结合实现。进一步的，所述起始RB和SSB的起始RB之间的偏移的RB数为最小偏移值或者最大偏移值；
其中，所述最小偏移值为：在所述第一CORESET的RB包括用于传输 SSB的RB，和/或，所述第一CORESET的所有RB包含在所述第二CORESET的RB集合内情况下，所述起始RB和SSB的起始RB之间的最小偏移RB数，
所述最大偏移值为：在所述第一CORESET的RB包括用于传输SSB的RB，和/或，所述第一CORESET的所有RB包含在所述第二CORESET的RB集合内情况下，所述起始RB和SSB的起始RB之间的最大偏移RB数。
需要说明的是，在所述第一CORESET的RB包括用于传输SSB的RB的情况下，或者，在所述第一CORESET的所有RB包含在所述第二CORESET的RB集合内情况下，或者，在所述第一CORESET的RB包括用于传输SSB的RB，且所述第一CORESET的所有RB包含在所述第二CORESET的RB集合内情况下，上述第一CORESET的起始RB可以存在多个取值，也就是说，第一CORESET的起始RB为这多个中的任一值时，都满足上述条件，而该实施方式中，可以实现第一CORESET的起始RB为最小偏移RB数或者最大偏移RB数，以实现第一CORESET的RB最少或者最多。
下面以满足第一CORESET的带宽能包含所有传输SSB的RB，且第一CORESET的所有RB资源包含在第二CORESET的RB资源范围内这一条件，进行举例说明：
参见图4所示，S1和S2分别表示SSB的起始RB和结束RB，O1表示第二CORESET的起始RB和SSB的起始RB的偏移的RB数，BW1表示第二CORESET的带宽，BW2表示第一CORESET的带宽，O12表示第二CORESET的起始RB和第一CORESET的起始RB，O2第一CORESET的起始RB和SSB的起始RB的偏移的RB数。这样得到O12使得O12<＝S1,O12+BW2<＝BW1，其中，BWs＝S2-S1+1为SSB的RB数。S1＝O1-1为传输SSB的第一个RB的编号，该编号以第一CORESET#0(宽带CORESET#0)的RB#0的载波#0开始计数。
在一种方式，可以根据网络配置的第二CORESET的起始RB开始，以X个RB为颗粒度向上滑动，找到第一个满足上述条件的RB作为第一CORESET的起始RB，X可以为1，2，……。例如，如图5所示，找到第三个CORESET作为第一CORESET，前面两个CORESET可以忽略。
进一步的，可以使用下面的公式反映上述第一CORESET的起始RB编 号：
Figure PCTCN2020101040-appb-000001
其中，k以RB为单位，可以从0开始以1个或者2个RB为单位的自然数集合，O 2＝O 1-O 12。
在另一种方式，可以根据网络配置的第二CORESET的起始RB开始，以X个RB为颗粒度向上滑动，找到最后一个满足上述准则的RB作为第二CORESET的起始RB，X可以为1，2，……。
进一步的，可以使用下面的公式反映上述第一CORESET的起始RB编号：
Figure PCTCN2020101040-appb-000002
其中，k以RB为单位，可以从0开始以1个或者2个RB为单位的自然数集合。
在另一种方式，可以根据如下公式反映上述第一CORESET的起始RB编号：
Figure PCTCN2020101040-appb-000003
Figure PCTCN2020101040-appb-000004
Figure PCTCN2020101040-appb-000005
或者
Figure PCTCN2020101040-appb-000006
这样O 2＝O 1-O 12。
也就是说，可以依据所述第二CORESET的带宽、用于传输同步信号块SSB的带宽和所述第一CORESET的带宽确定第一CORESET的起始RB。
当然，本公开实施例并不限定通过上述方式确定第一CORESET的起始RB，例如：在不限定满足第一CORESET的所有RB资源包含在第二CORESET的RB资源范围内这一条件时，可以使用简单的规则，即O 2默认配置是一个固定的值，网络部署保证该默认配置能保证该第一CORESET的资源在网络的信道带宽内。
可选的，所述PDCCH search space为Type-0 PDCCH search space；
其中，所述Type-0 PDCCH search space的监听时机(monitoring occasion)为所述第二CORESET的Type-0 PDCCH search space的监听时机；或者
所述Type-0 PDCCH search space的监听时机为所述第二CORESET的 Type-0 PDCCH search space的监听时机所在的时隙slot内第一OFDM符号上，所述第二CORESET的Type-0 PDCCH search space的监听时机为所述slot内的第二OFDM符号上；或者
所述Type-0 PDCCH search space的监听时机为相对于所述第二CORESET的Type-0 PDCCH search space的监听时机的偏移。
其中，上述Type-0 PDCCH search space可以是默认参数，或者网络指示的，例如：上述Type-0 PDCCH search space使用默认参数的情况下，上述Type-0 PDCCH search space的monitoring occasion可以是在第二CORESET的Type0 PDCCH search space对应的monitoring occasion上监听，或者，上述Type-0 PDCCH search space的monitoring occasion在相对于第二CORESET的Type0 PDCCH search space对应的monitoring occasion有固定偏移的时间资源上监听，该固定偏移可以是帧、半帧、子帧、slot或者OFDM符号为单位的偏移。而上述Type-0 PDCCH search space由网络指示部分参数的情况下，上述Type-0 PDCCH search space的monitoring occasion在相对于第二CORESET的Type0 PDCCH search space对应的监听时间资源的偏移，该偏移可以是帧、半帧、子帧、slot或者OFDM符号的偏移。
需要说明的是，本公开实施例中，上述Type-0 PDCCH search space的参数可以包括如下至少一项：
O：子帧的偏移
M：相邻SSB关联的PDCCH的监听时隙的时间颗粒度
N：每个slot内的搜索空间集合的数目
First symbol index:在slot内监听PDCCH的起始OFDM符号。
例如：对于第一CORESET的Type-0 PDCCH search space默认参数，终端可以假设使用和第二CORESET的Type-0 PDCCH search space配置相同的search space；或者使用默认的时间偏移的时间资源上进行监听，例如第一CORESET的Type-0 PDCCH search space的监听的时间资源和第二CORESET的Type-0 PDCCH search space的时间资源有确定的子帧、时隙或者符号的偏移。例如，在和第二CORESET的Type-0 PDCCH search space监听相同的时隙上的第6或者7个OFDM符号上进行监听；或者在第二CORESET的Type-0  PDCCH search space监听的时隙之后的下一个半帧(5ms)或者帧(10ms)的时隙上进行监听。

在所述PBCH中指示的用于PDSCH接收的DMRS配置；或者
在所述PBCH中指示的用于PDSCH接收的DMRS配置的偏移；或者
默认的DMRS配置；或者
所述DMRS配置为Type-A DMRS的第一个OFDM符号的所在OFDM符号的配置。
其中，上述Type-A DMRS为协议中定义的Type-A DMRS，例如：在PBCH中可以指示Type-A DMRS的位置。
该实施方式中，可以实现对所述第一CORESET中的PDCCH调度的PDSCH进行接收的DMRS配置为默认的DMRS配置，或者，终端使用默认或者网络指示的Type-A DMRS的第一个OFDM符号所在的OFDM符号索引，例如OFDM符号3(从0计数)。
以及还可以实现对所述第一CORESET中的PDCCH调度的PDSCH进行接收的DMRS配置PBCH中指示的用于PDSCH接收的DMRS配置，如使用相同的配置或者根据PBCH中指示的用于PDSCH接收的DMRS配置偏移Y个符号确定。其中，PBCH中指示的用于PDSCH接收的DMRS配置可以是PBCH中指示的第二BWP上的PDSCH接收的DMRS配置，其中，第二BWP可以是包含的RB与第二CORESET包含的RB相同的初始BWP，而对所述第一CORESET中的PDCCH调度的PDSCH进行接收可以是，在第一BWP中接收PDSCH，第一BWP可以是包含的RB与第一CORESET包含的RB相同的初始BWP。
该实施方式中，可以减少DMRS配置，以节约传输开销。
作为一种可选的实施方式，在所述通信设备为终端的情况下，所述在第一CORESET中进行PDCCH的传输，包括：
在所述第一CORESET中的PDCCH search space监听PDCCH；
其中，所述监听PDCCH包括使用默认的第一监听参数作为假设进行监听，或者使用第二监听参数进行监听，所述第二监听参数与在所述第二CORESET中的PDCCH search space监听PDCCH的监听参数对应。
其中，所述第一监听参数可以包括如下至少一项：
DMRS的参考点、下行控制信息(Downlink Control Information，DCI)比特数、绑定资源粒子组(REG bundle)大小和交织长度(interleave size)大小。
上述DMRS的参考点可以为所述第二CORESET的起始RB的起始子载波(Sub Carrier，SC)。例如：在所述第一CORESET中的PDCCH search space监听PDCCH时，使用和第二CORESET的RB#0的SC#0作为PDCCH的DMRS的参考点，该参考点为DMRS序列生成的子载波。
而上述DCI比特数可以为在所述第二CORESET中的PDCCH search space监听PDCCH的对应的格式(format)的DCI比特数。例如：在所述第一CORESET中的PDCCH search space监听PDCCH时，使用第二BWP的带宽，作为DCI size的长度。
而上述REG bundle大小可以为在所述第二CORESET中的PDCCH search space监听PDCCH的REG bundle大小。例如：在所述第一CORESET中的PDCCH search space监听PDCCH时，使用在所述第二CORESET中的PDCCH search space监听PDCCH的REG bundle大小。
而上述interleave size可以为在所述第二CORESET中的PDCCH search space监听PDCCH的interleave size大小。例如：在所述第一CORESET中的PDCCH search space监听PDCCH时，使用在所述第二CORESET中的PDCCH search space监听PDCCH的interleave size大小。
当然，上述部分或者全部参数也可以是使用默认的参数，例如：使用默认的REG bundle size和interleave size的假设，如使用和第一Type0-PDCCH相同的REG bundle size和interleave size进行监听。
可选地，所述终端是否使用所述第一监听参数作为假设进行监听由网络指示，从而灵活地配置终端的行为，例如：可以通过PBCH、系统信息块(system information block，SIB)、RRC、MAC-CE或者PDCCH指示。
作为一种可选的实施方式，在所述通信设备为终端的情况下，所述方法还包括：
接收PDCCH调度的PDSCH，接收所述PDSCH在第一BWP中进行接收，所述第一BWP包含的RB和所述第一CORESET包含的RB相同；
其中，所述接收PDSCH以第一接收参数为假设进行接收，所述第一接收参数与第二接收参数对应，所述第二接收参数为在所述第二CORESET上传输的Type0 PDCCH调度的PDSCH的接收参数。
上述第一BWP可以是初始BWP，即可以称作第一初始BWP。
其中，所述第一接收参数可以包括如下至少一项：
DMRS的参考点和预编码资源块组(Precoding Resource Group，PRG)大小。
其中，所述DMRS的参考点可以为所述第二CORESET的起始RB的SC，或者默认参数。例如：在接收PDCCH调度的PDSCH时，使用和第二BWP的RB#0的SC#0作为PDSCH的DMRS的参考点。
所述PRG大小可以为在所述第二CORESET上接收PDSCH的PRG大小，且PRG从所述第二CORESET的起始RB开始划分，或者默认参数例如：在接收PDCCH调度的PDSCH时，使用和第二BWP的PRG size相同的假设，从第二BWP的RB#0开始进行划分。
可选地，所述终端是否使用第一接收参数为假设进行接收由网络指示，从而灵活地配置终端的行为，例如：可以通过PBCH、SIB、RRC、MAC-CE或者PDCCH指示。
作为一种可选的实施方式，在所述通信设备为终端的情况下，所述终端是否在所述第一CORESET中进行接收由网络指示；或者
所述终端基于所述第一CORESET的资源参数为假设，在所述第一CORESET中进行接收，如果成功第一接收系统信息块(SIB1)，则确认网络有进行所述第一CORESET的传输。
其中，上述网络指示可以是由网络显示指示，显示指示信息由PBCH或者系统信息指示，当然，也可以是隐示指示，对此不作限定。
上述SIB可以是协议中定义的SIB1。
上述终端基于所述第一CORESET的资源参数为假设，在所述第一CORESET中进行接收，如果成功第一接收系统信息块(SIB1)，则确认网络有进行所述第一CORESET的传输可以是，终端基于所述第一CORESET的资源参数为假设，在所述第一CORESET中进行接收，如果该资源参数与第二CORESET的资源参数不同，且成功SIB1，则确认网络有进行所述第一CORESET的传输。例如：终端基于窄带宽的参数假设进行第一Type0 PDCCH(第一CORESET内的PDCCH)的接收，如果该接收参数与第二Type0PDCCH(第二CORESET内的PDCCH)接收的参数不同，且终端能成功接收第一Type0 PDCCH则认为网络进行了第一CORESET的传输。其中，进行了第一CORESET的传输也可以理解为进行了第一BWP的传输，因为，第一BWP包含的RB与第一CORESET包含的RB相同。
例如：网络侧可以使用PBCH中的对应于SSB index的低两位比特来指示网络是否进行第一CORESET的传输。
例如：使用第
Figure PCTCN2020101040-appb-000007
比特进行指示，其中
Figure PCTCN2020101040-appb-000008
是高层生成的比特数，物理层的8比特为
Figure PCTCN2020101040-appb-000009
或者使用
Figure PCTCN2020101040-appb-000010
进行指示，
Figure PCTCN2020101040-appb-000011
为高层生成比特的最后一比特。
上述信息可以直接指示网络是否支持终端在窄带的第一CORESET的进行接收。终端可以基于前述的默认参数假设，或者规则，确定第一CORESET，以及第一CORESET的第一search space#0的配置。
或者用于指示第一CORESET的带宽，RB OFFSET，第一search space#0的参数，DMRS配置参数等。终端检测到这些字段，获得了这些信息,对应的比特位置0，则认为网络不支持进行窄带第一CORESET上进行传输。否则，认为网络支持进行窄带第一CORESET的传输，终端可以在窄带第一CORESET上进行接收。
对于一些终端(例如：老版本终端),即只支持读取第二CORESET、第二Type0-PDCCH公共搜索空间集(common search space set，CSS set)配置的终端，这些比特或者码点的指示没有意义，仍然会按照除这些比特之外的信息确定在第一初始BWP上的接收方法。对于能够通过读取PBCH传输的信息确定该SSB关联了第一CORESET、第一Type0-PDCCH CSS set、第一 初始BWP的终端，则可以使用第一CORESET、第一Type0-PDCCH CSS set、第一初始BWP和对应的接收参数为接收假设进行接收。这样，指示信息不影响正常终端在相关技术中的PBCH指示宽带初始下行BWP上工作，保证了兼容性。
作为一种可选的实施方式，所述第一CORESET的所有RB为所述第二CORESET的部分RB。
该实施方式中，由于第一CORESET的所有RB为所述第二CORESET的部分RB从而支持终端工作在较窄的带宽上，以终端UE功耗。
进一步地，所述第一CORESET和所述第二CORESET可以使用相同的资源传输系统信息。
其中，所述第一CORESET和所述第二CORESET可以使用相同的资源传输系统信息可以是使用相同的PDCCH和PDSCH资源进行SIB的传输，例如：终端实际接收的PDCCH和SIB的传输PDSCH是相同的。这样，从网络的角度降低了开销。
本公开实施例中，在第一CORESET中进行PDCCH的传输，其中，所述第一CORESET的RB数小于或者等于第二CORESET的RB数，所述第二CORESET由PBCH中的高层信令配置。这样，可以配置两个CORESET，从而提高终端接收PDCCH的性能。
