在第三方面中，在终端设备初始接入成功之前和之后，第一控制资源集合的频域位置可以依据不同的下行带宽部分的频域位置来确定，但由于设定不同下定带宽的起始公共资源块位置是相同的，依旧可以使得以不同的下行带宽部分为参考的第一控制资源集合的频域位置是相同的，这样终端设备和网络设备仅需要计算一次第一控制资源集合的频域位置， 降低了确定第一控制资源集合的频域位的复杂度。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例进行说明。
请参见图1，图1是本申请实施例涉及的一种可能的通信系统的架构示意图。如图1所示，该通信系统包括网络设备101和终端设备102。网络设备101和终端设备102可以通过通信系统的空口技术进行通信，其中包括在下行物理控制信道(physical downlink control channel，PDCCH)传输上下行调度控制信息的场景。
其中PDCCH包括commonControlResourceSet的时频位置。对于commonControlResourceSet的频域位置，即公共资源块(common resource block，CRB)的位置，是以当前激活的下行带宽部分为参考确定的。例如，当前激活下行带宽部分是初始下行带宽部分时，commonControlResourceSet的CRB位置是以初始下行带宽部分为参考确定的。对于终端设备而言，在commonControlResourceSet的频域位置可以监听下行物理控制信道以获得上下行调度控制信息，对于网络设备而言，在commonControlResourceSet的频域位置可以在下行物理控制信道发送上下行调度控制信息，例如上下行调度控制信息可以为调度随机接入响应的控制信息、调度寻呼消息的控制信息或者调度系统消息的控制信 息等。
在现有的技术方案中，初始下行带宽部分(initial downlink bandwidth part，initial DL BWP)存在两种配置方式，一种是通过CORESET#0定义，这一情况下初始下行带宽部分的大小和频域位置与CORESET#0相同，其中CORESET为控制资源集合(control resource set)；另一种是在系统消息块1(System Information Block 1，SIB 1)中配置initial DL BWP。在终端设备初始接入成功之前，以CORESET#0定义的初始下行带宽部分生效；在终端设备初始接入成功之后，以SIB 1中配置的initial DL BWP生效，SIB 1配置的initial DL BWP可以与CORESET#0定义的initial DL BWP不同，但SIB 1中配置的initial DL BWP的频域位置要包含CORESET#0的频域位置。
当CORESET#0的频域位置与SIB 1配置的initial DL BWP的频域位置不一致时，分别以这两种配置确定的commonControlResourceSet的频域位置也是不同的。如图2所示，为本申请实施例提供了一种可能的公共控制资源集合的频域位置的示例图。
如图2所示，可以看出CORESET#0的频域位置与SIB1配置的initial DL BWP的频域位置不一致，且CORESET#0的起始资源块位置RB-x与SIB1配置的initial DL BWP的起始资源块位置RB-y不同，这一情况下根据CORESET#0定义的初始下行带宽部分确定的commonControlResourceSet 1的起始资源块位置，与根据SIB1配置的initial DL BWP确定的commonControlResourceSet 2的起始资源块位置也是不同的。
对于终端设备而言，在终端设备初始接入成功之前，按照commonControlResourceSet 1的频域位置监听调度随机接入响应、寻呼和系统消息的控制信息等；在终端设备初始接入成功之后，按照commonControlResourceSet 2的频域位置监听调度随机接入响应、寻呼和系统消息的信息等。
对于网络设备而言，在网络设备的覆盖范围内如果存在初始接入成功的终端设备和未接入成功的终端设备，网络设备需要在commonControlResourceSet 1的频域位置上向未接入成功的终端设备发送随机接入响应、寻呼和系统消息的调度信息等；以及需要在commonControlResourceSet 2的频域位置上向初始接入成功的终端设备发送随机接入响应、寻呼和系统消息的调度信息等。
可以看出，在图2的场景下，现有方案中在终端设备初始接入成功前后，计算出的commonControlResourceSet的频域位置不同。这样导致相同的公共信息会在不同的频域资源上发送，而且终端设备和网络设备均会针对是否接入成功的情况来分别计算commonControlResourceSet的频域位置，增加了确定commonControlResourceSet的频域位置的复杂度。
本申请的图3至图15的实施例，可以实现在终端设备初始接入成功前后计算出的commonControlResourceSet的频域位置是相同的，这样终端设备和网络设备仅需要计算一次commonControlResourceSet的频域位置，降低了确定commonControlResourceSet的频域位的复杂度。具体可以以下参见本申请图3至图15的实施例的详细描述。
本申请涉及的终端设备可以指用户设备(user equipment，UE)，可以为手持终端、笔记本电脑、用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能电话(smart phone)、个人数字助理(personal digital assistant，PDA)电脑、平板型电脑、无线调制解调器(modem)、 手持设备(handheld)、膝上型电脑(laptop computer)、无绳电话(cordless phone)或者无线本地环路(wireless local loop，WLL)台、机器类型通信(machine type communication，MTC)终端或是其他可以接入移动网络的设备。终端设备与网络设备之间采用某种空口技术相互通信。
本申请涉及的网络设备可以指接入网设备，主要负责空口侧的无线资源管理、服务质量(quality of service，QoS)管理、数据压缩和加密等功能。网络设备可以包括各种形式的基站，例如：宏基站，微基站(也称为小站)，中继站，接入点等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如，在第五代(5th generation，5G)系统中，称为gNB；在第四代(4th generation，4G)系统中，称为演进的节点B(evolved NodeB，eNB或者eNodeB)等。
可以理解的是，本申请涉及的第一控制资源集合还可以是公共控制资源集合或者其他方式命名的控制资源集合，本申请实施例对此不做限定。
本申请实施例还可应用于其它需要确定控制资源集合的频域位置的通信系统中。术语“系统”可以和“网络”相互替换。本申请实施例描述的系统架构是为了便于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，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。在本申请的描述中，“多个”是指两个或多于两个，“至少两个”是指两个或多于两个。
接下来对本申请实施例的具体实现方式进行介绍。
基于图1所示的通信系统，请参见图3，为本申请实施例提供了一种用于确定控制资源集合的频域位置的方法的流程示意图。图3所示的方法包括步骤301至步骤303。
301，在终端设备初始接入成功之前，网络设备向终端设备发送第一控制资源集合的配置信息。
相应的，在终端设备初始接入成功之前，终端设备接收第一控制资源集合的配置信息。
302，在终端设备初始接入成功之前，网络设备根据第一控制资源集合占用的第一公共资源块集合，在下行物理控制信道上发送上下行调度控制信息。
相应的，在终端设备初始接入成功之前，终端设备根据第一控制资源集合占用的第一公共资源块集合，监听下行物理控制信道以获得上下行调度控制信息。
303，在终端设备初始接入成功之后，网络设备根据第一控制资源集合占用的第一公共资源块集合，在下行物理控制信道上发送上下行调度控制信息。
相应的，在终端设备初始接入成功之后，终端设备根据第一控制资源集合占用的第一公共资源块集合，监听下行物理控制信道以获得上下行调度控制信息。
由于网络设备发送上下行调度控制信息数量是不确定的，因此本申请实施例对步骤302、步骤303的执行次数不做限定。
其中，配置信息用于指示第一控制资源集合在第一下行带宽部分内占用的物理资源块(physical resource block，PRB)的位置。本申请的第一控制资源集合的标识不为0。
可选的，第一控制资源集合的配置信息可以从SIB 1中获得，且该配置信息在终端设备初始接入成功之前后均可以生效，这里的生效是指：终端设备可以根据第一控制资源集 合的频域位置监听下行物理控制信道以获得上下行调度控制信息；或者，网络设备可以根据第一控制资源集合的频域位置在下行物理控制信道发送上下行调度控制信息。
可选的，在包含第一下行带宽部分是由SIB 1配置的initial DL BWP的场景中，第一下行带宽部分的配置信息也可以从SIB 1中获得，但SIB 1配置的第一下行带宽部分的配置信息是在终端设备初始接入成功之后生效，这里的生效是指：可以根据SIB 1配置的第一下行带宽部分的频域位置接收下行控制信息，或者，网络设备可以根据SIB 1配置的第一下行带宽部分的频域位置发送下行控制信息。其中，终端设备可以利用第一下行带宽部分的一个高层信令locationAndBandwidth和/或其他参数确定第一下行带宽部分的频域位置。
第一控制资源集合占用的第一公共资源块包括第一起始公共资源块和第一控制资源集合占用的公共资源块。在本申请实施例中，网络设备和终端设备均可以实现确定第一起始公共资源块，以及均可以实现根据配置信息和所参考的下行带宽部分的起始公共资源块确定第一控制资源集合占用的由第一起始公共资源块起始的公共资源块。对于如何确定第一起始公共资源块可以分为以下两种情况(第A1种情况和第A2种情况)来介绍。
在第A1种情况中，请参见图4，为本申请实施例提供了一种控制资源集合的频域位置的示例图。在图4中，第一下行带宽部分是由CORESET#0定义的initial DL BWP，第一控制资源集合的第一起始公共资源块是根据CORESET#0的第二起始公共资源块和第一控制资源集合的配置信息确定的。具体的，在确定CORESET#0的第二起始公共资源块之后，确定第一起始公共资源块的详细过程可以参见图6的详细介绍，其中，第四偏移是指CORESET#0的第二起始公共资源块与第一控制资源集合的第一起始公共资源块相差的公共资源块的数量。
其中，CORESET#0的第二起始公共资源块是指CORESET#0占用的最小CRB；第一控制资源集合的第一起始公共资源块是指第一控制资源集合占用的最小CRB。CORESET#0的第二起始公共资源块是根据CORESET#0的第二起始物理资源块和第一偏移确定的，第一偏移用于指示第二起始物理资源块与参考点之间相差的物理资源块的数量，参考点是资源块网格的一个公共参考点，参考点用于指示以预设子载波间隔配置的公共资源块CRB 0中的子载波0的中心位置。如图4所示，公共参考点可以为参考点A(point A)的位置，指示的是公共资源块CRB 0中的子载波0的中心位置。
第一偏移是根据第一下行带宽部分的第二起始物理资源块与SS/PBCH block(Synchronization/Physical Broadcast Channel block，同步/物理广播信道块)的第三起始物理资源块之间的第二偏移和SS/PBCH block的公共资源块偏移确定的。其中，第二偏移用于指示第二起始物理资源块与SS/PBCH block的第三起始物理资源块之间相差的物理资源块数量；SS/PBCH block的公共资源块偏移用于指示第三起始物理资源块与参考点之间相差的物理资源块的数量，如图4所示的相对于参考点A的偏移

这样第一偏移等于
Figure PCTCN2019128916-appb-000002
减去第二偏移的值。其中，第三起始物理资源块为与SS/PBCH block的第一个RB重叠的CRB的RB索引值最小的RB。
这里仅简单介绍了CORESET#0的第二起始公共资源块的确定方式，进一步可以请参见图8的详细描述。
基于第A1种情况，可选的，在实际应用中可以只通过CORESET#0来第一下行带宽部 分，这样只能以CORESET#0定义的第一下行带宽部分确定第一控制资源集合的频域位置。或者，可选的，在实际应用中可以通过CORESET#0定义第一下行带宽部分和由SIB 1配置第一下行带宽部分，在这一情况下，选择以CORESET#0定义的第一下行带宽部分确定第一控制资源集合的频域位置。
对于终端设备而言，在终端设备初始接入成功之前，可以在SIB 1消息中获得第一控制资源集合的配置信息，对于网络设备而言，在终端设备初始接入成功之前，可以在SIB 1消息中携带第一控制资源集合的配置信息。终端设备和网络设备可以根据CORESET#0的第二起始公共资源块确定第一控制资源集合的第一起始公共资源位置，在终端设备初始接入成功之前，终端设备根据图4所示的第一控制资源集合1监听下行物理控制信道以获得上下行调度控制信息，网络设备根据图4所示的第一控制资源集合1在下行物理控制信道发送上下行调度控制信息。在终端设备初始接入成功之后，终端设备根据图4所示的第一控制资源集合2监听下行物理控制信道以获得上下行调度控制信息，网络设备根据图4所示的第一控制资源集合2在下行物理控制信道发送上下行调度控制信息。这一方式所确定第一控制资源集合的频域位置是相同的，终端设备和网络设备只需要计算一次第一控制资源集合的位置，降低了确定第一控制资源集合的频域位置复杂度。
本申请实施例对第一控制资源集合的频域位置的确定时刻不做限定，可以在终端设备初始接入成功之前根据该配置信息和CORESET#0定义的第一下行带宽部分的频域位置确定第一控制资源集合的频域位置，或者可以在初始接入成功之后根据该配置信息和CORESET#0定义的第一下行带宽部分的频域位置确定第一控制资源集合的频域位置。
在第A2种情况中，请参见图5，为本申请实施例提供了另一种控制资源集合的频域位置的示例图。在图5中，第一下行带宽部分是由SIB 1配置的initial DL BWP，第一控制资源集合的第一起始公共资源块是根据SIB 1配置的第一下行带宽部分的第二起始公共资源块和第一控制资源集合的配置信息确定的。具体的，在确定SIB 1配置的第一下行带宽部分的第二起始公共资源块之后，确定第一控制资源集合的第一起始公共资源块的详细过程可以参见图6的详细介绍，其中，第五偏移是指SIB 1配置的第一下行带宽部分的第二起始公共资源块与第一控制资源集合的第一起始公共资源块相差的公共资源块的数量。
其中，在第一下行带宽部分为根据SIB 1配置的情况下，第一下行带宽部分的第二起始公共资源块是根据第一下行带宽部分的第二起始物理资源块和第三偏移确定的；其中，第三偏移用于指示第二起始物理资源块与参考点之间相差的物理资源块的数量，参考点是资源块网格的一个公共参考点，参考点用于指示以预设子载波间隔配置的公共资源块CRB 0中的子载波0的中心位置。如图5所示，公共参考点可以为参考点A(point A)的位置，指示的是公共资源块CRB 0中的子载波0的中心位置。这里仅简单介绍了SIB 1配置的第一下行带宽部分的第二起始公共资源块的确定方式，详细的介绍，请参见图8的详细描述。
基于第A2种情况，可选的，在实际应用中可以只有一种通过SIB 1来配置第一下行带宽部分的方式，在该情况中只能以SIB 1配置的第一下行带宽部分确定第一控制资源集合的频域位置。或者，可选的，在实际应用中可以通过CORESET#0和SIB 1配置第一下行带宽部分，在这一情况下，选择以SIB 1配置的第一下行带宽部分确定第一控制资源集合的频域位置。
对于终端设备而言，在终端设备初始接入成功之前，可以在SIB 1消息中获得第一控制资源集合的配置信息，对于网络设备而言，在终端设备初始接入成功之前，可以在SIB 1消息中携带第一控制资源集合的配置信息。终端设备和网络设备可以根据SIB 1配置的第一下行带宽部分的第二起始公共资源块确定第一控制资源集合的第一起始公共资源位置，在终端设备初始接入成功之前，终端设备根据图5所示的第一控制资源集合1监听下行物理控制信道以获得上下行调度控制信息，网络设备根据图5所示的第一控制资源集合1在下行物理控制信道发送上下行调度控制信息。在终端设备初始接入成功之后，终端设备根据图5所示的第一控制资源集合2监听下行物理控制信道以获得上下行调度控制信息，网络设备根据图5所示的第一控制资源集合2在下行物理控制信道发送上下行调度控制信息。这一方式所确定第一控制资源集合的频域位置是相同的，终端设备和网络设备只需要计算一次第一控制资源集合的位置，降低了确定第一控制资源集合的频域位置复杂度。
本申请实施例对终端设备对第一控制资源集合的频域位置的确定时刻不做限定，可以在终端设备初始接入成功之前根据该配置信息和SIB 1配置的第一下行带宽部分的频域位置确定第一控制资源集合的频域位置，或者可以在终端设备初始接入成功之后根据该配置信息和SIB 1配置的第一下行带宽部分的频域位置确定第一控制资源集合的频域位置。
其中，图3、图4和图5中时刻T表示终端设备初始接入成功的时刻。网络设备和终端设备对于时刻T的认定可能不同。在可选的实现方式中，对于终端设备而言，终端设备确定初始接入成功的时刻用于指示以下(3-1)、(3-2)、(3-3)、(3-4)、(3-5)、(3-6)的其中一个时刻：
(3-1)终端设备成功接收初传的消息4并向网络设备发送确认消息的时刻；
(3-2)在终端设备成功接收初传的消息4之后，终端设备成功接收到由小区无线网络临时标识(cell radio network temporary identifier，C-RNTI)加扰的下行控制信息DCI的时刻；
(3-3)终端设备成功接收重传的消息4并向网络设备发送确认消息的时刻；
(3-4)终端设备在终端设备成功接收重传的消息4之后，终端设备成功接收到由小区无线网络临时标识C-RNTI加扰的下行控制信息DCI的时刻；
(3-5)终端设备成功接收初传的消息4之后成功接收到用于指示需盲检C-RNTI加扰的DCI的配置信息的时刻；
(3-6)终端设备成功接收重传的消息4之后成功接收到用于指示需盲检C-RNTI加扰的DCI的配置信息的时刻。
对于网络设备而言，网络设备确定初始接入成功的时刻用于指示以下(3-7)、(3-8)、(3-9)、(3-10)的其中一个时刻：
(3-7)网络设备接收到终端设备发送的针对网络设备发送的初传消息4的确认消息的时刻；
(3-8)网络设备接收到终端设备发送的针对网络设备发送的重传消息4的确认消息的时刻；
(3-9)网络设备接收到终端设备发送的针对网络设备发送的初传消息4的确认消息之后，向终端设备发送用于指示需盲检C-RNTI加扰的DCI的配置信息的时刻；
(3-10)网络设备接收到终端设备发送的针对网络设备发送的重传消息4的确认消息 之后，向终端设备发送用于指示需盲检C-RNTI加扰的DCI的配置信息的时刻。
在本申请实施例中，在终端设备初始接入成功之前后的第一控制资源集合的频域位置是相同的，这样终端设备和网络设备仅需要计算一次第一控制资源集合的频域位置，降低了确定第一控制资源集合的频域位的复杂度。
请参见图6，为本申请提供了一种下行带宽部分与第一控制资源集合的频域位置的示例图。在1个小区的1个DL BWP内，网络设备可以通过高层信令frequencyDomainResources来指示第一控制资源集合在1个BWP内的资源分配。这里的frequencyDomainResources即为本申请涉及的第一控制资源集合的配置信息。根据协议描述，frequencyDomainResources是1个45比特的位图(bit-map)。45-bitmap指示第一控制资源集合在第一下行带宽部分内的频域资源分配，每1比特指示了连续6个不重叠的物理资源块(Physical Resource block，PRB)。第一控制资源集合的第一起始公共资源块索引是与公共资源块索引的6的倍数对齐的。
如图6所示，假设下行带宽部分的起始公共资源块索引为
Figure PCTCN2019128916-appb-000003
则由于第一控制资源集合的第一起始公共资源块的索引(index)必须是6的倍数，因此frequencyDomainResources的起始公共资源块是
Figure PCTCN2019128916-appb-000004
具体是指45-bitmap的第1个比特指示的6个PRB从CRB 36开始，依次往上排。如果比特值取值为1表示对应的6个连续的PRB分配给第一控制资源集合，如果比特值取值为0表示对应的6个连续的PRB不分配给第一控制资源集合。如果比特指示的PRB部分超过了下行带宽部分，那么超过的部分就都置为0，表示不分配给第一控制资源集合。
举例来说，frequencyDomainResources＝“00000111111110……”的情况下，可以看出前5个bit对应的30个PRB均未跟配给第一控制资源集合，第一控制资源集合的第一起始公共资源块的索引为36+30＝66，即第一控制资源集合的第一起始公共资源块为CRB 66。以图6的下行带宽部分为图4所示情况中由CORESET#0定义的第一带宽的情况下，这样图4的第四偏移可以为CRB 66-CRB 33＝CRB 33，具体是指第一控制资源集合的第一起始公共资源块与下行带宽部分的起始公共资源块之间相差33个公共资源块。
可选的，图6中涉及的下行带宽部分(DL BWP)可以为由CORESET#0定义的初始下行带宽部分，或者可以为由SIB 1配置的初始下行带宽部分，或者可以为新配置的initial DL BWP，或者可以为其他DL BWP等。对于上述下行带宽部分的各种可能的配置情况，均可以参考图6描述的根据下行带宽部分的公共起始位置和第一控制资源集合的配置信息，来确定第一控制资源集合的第一起始公共资源块。
进一步的，请参见图7，为本申请实施例提供了一种第一控制资源集合的时域资源的示例图。在具体实现中，网络设备可以通过高层信令(例如无线资源控制(Radio Resource Control,RRC)信令)第一控制资源集合的配置消息为终端设备配置一个第一控制资源集合，其中包含第一控制资源集合的CORESET id、频域资源指示、时域上持续OFDM符号个数、等参数。时域上持续OFDM符号个数可以取值为1，2和3中的1个值。频域资源指示可以为图6所示的45-bit的位图。网络设备通过高层信令(例如RRC信令)SearchSpace配置消息配置给终端设备1个搜索空间集合，其中包含search space set id、1个时隙(slot) 的监听时刻(monitoring occasion)指示、聚集级别以及对应的备选PDCCH个数等参数。例如：在searchSpace内盲检的第一控制资源集合的时域位置如图7所示，搜索空间在1个slot 0内的监听时刻指示在1个slot 0内的第一个符号上，且搜索空间中的CORESET id对应的第一控制资源集合在时域上持续3个符号，如图7中的符号0至符号2。第一控制资源集合的频域资源位置由45-bit位图确定。另外，确定第一控制资源集合的频域位置的具体过程可以参考如图6所示方法的介绍。
而下行带宽部分是由CORESET#0定义或者由SIB 1配置的情况下，假设CORESET#0定义的初始下行带宽部分用下行带宽部分一表示，假设由SIB 1配置的初始下行带宽部分用下行带宽部分二表示，则下行带宽部分一和下行带宽部分二的频域位置的详细确定过程可以参见图8的详细描述。为了便于适用于各个实施例，这里下行带宽部分一的公共资源块用第五公共资源块来表示，第五公共资源块包括第五起始公共资源块以及下行带宽部分一占用的其他公共资源块；这里下行带宽部分二的公共资源块用第六公共资源块来表示，第六公共资源块包括第六起始公共资源块以及下行带宽部分二占用的其他公共资源块。
(1)终端设备在工作带宽内检测到SS/PBCH block后，MIB中ssb-SubcarrierOffset(K SSB)指示与SS/PBCH block的第一个RB重叠的CRB的RB索引值最小的RB和SS/PBCH block的第一个RB之间的子载波偏移量；与SS/PBCH block的第一个RB重叠的CRB的索引值最小的RB即为本申请中涉及的SS/PBCH block的第三起始物理资源块。
(2)获得MIB中pdcch-ConfigSIB 1的高4比特，高四位比特指示了SS/PBCH block与下行带宽部分一之间的第二偏移。
这里的第二偏移是指下行带宽部分一的第五起始物理资源块与SS/PBCH block的第三起始物理资源块之间相差的物理资源块数量，第二偏移以PRB为单位。
这样，可以根据SS/PBCH block的第三起始物理资源块和第二偏移，确定下行带宽部分一的第五起始物理资源块。
(3)根据在下行带宽部分一里面监听SI-RNTI加扰的DCI format 1_0，得到SIB 1的调度信息，在调度的时频资源上接收SIB 1消息。通过获得SIB 1消息中的ServingCellConfigCommonSIB，可以获得以下信息：
I、相对于参考点A的偏移(offsetToPointA)：用于指示cell-defining SS/PBCH block的第三起始物理资源位置到Point A之间的PRB偏移量；这里的第三起始物理资源位置是指与SS/PBCH block的第一个RB重叠的CRB的最小的索引值RB。
这样，可以根据offsetToPointA和SS/PBCH block的第三起始物理资源位置确定出SS/PBCH block的第三起始公共资源块，第三起始公共资源块是指与SS/PBCH block的第一个RB重叠的CRB的索引值最小的RB。
进一步的，offsetToPointA结合(2)中的第二偏移可以确定出第一偏移，根据第一偏移和下行带宽部分一的第五起始物理资源块可以确定出下行带宽部分一的第五起始公共资源块，第五起始公共资源块是指下行带宽部分一占用的最低公共资源块。
II、locationAndBandwidth：用于指示包含下行带宽部分二的起始物理资源块和所占的公共资源块的数量等信息，如图8所示。
III、carrierBandwidth：用于指示不同子载波间隔对应的一组载波以及每一个载波在频 域上的宽度；
OffsetToCarrier：用于指示每一个载波的最低可用的子载波到point A的频域偏移量，其中，Point A是Common RB的子载波0的中心位置。
这样结合II和III可以确定出下行带宽部分二的第六起始公共资源块和下行带宽部分二占用的其他公共资源块，第六起始公共资源块是指下行带宽部分二占用的最低公共资源块。
其中，本申请各个实施例中涉及的资源块网格是用于映射物理资源的。物理层进行资源映射的时候以时频资源单元(Resource Element,RE)为基本单位，一个RE由时域上一个符号和频域上一个子载波组成，一个时隙上所有OFDM符号和频域上12个子载波组成一个资源块(Resource Block,RB)，RE的位置用(k，l)表示，k表示OFDM的序号，l表示子载波的序号，通过给出坐标(k,l)就可以定位到指定的RE上。
可选的，在终端设备初始接入之前，网络设备配置了第一控制资源集合的配置信息的情况下，终端设备可以通过SIB 1消息中的ServingCellConfigCommonSIB获得第一控制资源集合的配置信息，进而可以确定以下行带宽部分一为参考的第一控制资源集合的第一起始公共资源块，或者确定以下行带宽部分二为参考的第一控制资源集合的第一起始公共资源块。
基于图1所示的通信系统，请参见图9，为本申请实施例提供了另一种用于确定控制资源集合的频域位置的方法的流程示意图。图9所示的方法包括步骤901和步骤902。
901，在终端设备初始接入成功之前，网络设备向终端设备发送第一控制资源集合的配置信息。
相应的，在终端设备初始接入成功之前，终端设备接收第一控制资源集合的配置信息。
902，在终端设备初始接入成功之后，网络设备根据第一控制资源集合占用的第一公共资源块集合，在下行物理控制信道上发送上下行调度控制信息。
相应的，在终端设备初始接入成功之后，终端设备根据第一控制资源集合占用的第一公共资源块集合，监听下行物理控制信道以获得上下行调度控制信息。
其中，配置信息用于指示第一控制资源集合在第一下行带宽部分内占用的物理资源块的位置。本申请的第一控制资源集合的标识不为0。
其中，在终端设备初始接入成功之前，终端设备不会根据第一控制资源集合占用的公共资源块集合监听下行物理控制信道。而且第一控制资源集合的频域位置是以一个下行带宽部分为参考来确定的，具体可以参见图10和图11的具体介绍。
可选的，第一控制资源集合的配置信息可以从SIB 1中获得，且该配置信息在终端设备初始接入成功之后可以生效，这里的生效是指：终端设备可以根据第一控制资源集合的频域位置监听下行物理控制信道以获得上下行调度控制信息；或者，网络设备可以根据第一控制资源集合的频域位置在下行物理控制信道发送上下行调度控制信息。
可选的，在包含第一下行带宽部分是由SIB 1配置的initial DL BWP的场景中，第一下行带宽部分的配置信息也可以从SIB 1中获得，但SIB 1配置的第一下行带宽部分的配置信息是在终端设备初始接入成功之后生效，这里的生效是指：可以根据SIB 1配置的第一下 行带宽部分的频域位置接收下行控制信息，或者，网络设备可以根据SIB 1配置的第一下行带宽部分的频域位置发送下行控制信息。其中，终端设备可以利用第一下行带宽部分的一个高层信令locationAndBandwidth和/或其他参数确定第一下行带宽部分的频域位置。
第一控制资源集合占用的第一公共资源块包括第一起始公共资源块和第一控制资源集合占用的其他公共资源块。在本申请实施例中，网络设备和终端设备均可以实现确定第一起始公共资源块，以及均可以实现根据配置信息和所参考的下行带宽部分的起始公共资源块确定第一控制资源集合占用的由第一起始公共资源块起始的公共资源块。对于如何确定第一起始公共资源块可以分为以下两种情况(第B1种情况和第B2种情况)来介绍。
在第B1种情况中，请参见图10，为本申请实施例提供了另一种控制资源集合的频域位置的示例图。在图10中，第一下行带宽部分是由CORESET#0定义的initial DL BWP，第一控制资源集合的第一起始公共资源块是根据CORESET#0的第二起始公共资源块和第一控制资源集合的配置信息确定的。具体的，在确定CORESET#0的第二起始公共资源块之后，确定第一起始公共资源块的详细过程可以参见图6的详细介绍，其中，第四偏移是指CORESET#0的第二起始公共资源块与第一控制资源集合的第一起始公共资源块相差的公共资源块的数量。
其中，CORESET#0的第二起始公共资源块是指CORESET#0占用的最小CRB；第一控制资源集合的第一起始公共资源块是指第一控制资源集合占用的最小CRB。CORESET#0的第二起始公共资源块是根据CORESET#0的第二起始物理资源块和第一偏移确定的，第一偏移用于指示第二起始物理资源块与参考点之间相差的物理资源块的数量，参考点是资源块网格的一个公共参考点，参考点用于指示以预设子载波间隔配置的公共资源块CRB 0中的子载波0的中心位置。如图10所示，公共参考点可以为参考点A(point A)的位置，指示的是公共资源块CRB 0中的子载波0的中心位置。
第一偏移是根据第一下行带宽部分的第二起始物理资源块与SS/PBCH block的第三起始物理资源块之间的第二偏移和SS/PBCH block的公共资源块偏移确定的。其中，第二偏移用于指示第二起始物理资源块与SS/PBCH block的第三起始物理资源块之间相差的物理资源块数量；SS/PBCH block的公共资源块偏移用于指示第三起始物理资源块与参考点之间相差的物理资源块的数量，如图10所示的相对于参考点A的偏移
Figure PCTCN2019128916-appb-000005
这样第一偏移等于
Figure PCTCN2019128916-appb-000006
减去第二偏移的值。其中，第三起始物理资源块为与SS/PBCH block的第一个RB重叠的CRB的RB索引值最小的RB。
这里仅简单介绍了CORESET#0的第二起始公共资源块的确定方式，进一步可以请参见图8的详细描述。
基于第B1种情况，可选的，在实际应用中可以只有一种配置第一下行带宽部分的方式，在该情况中是通过CORESET#0来定义的。或者，可选的，在实际应用中可以通过CORESET#0和SIB 1配置/定义第一下行带宽部分，在这一情况下，选择以CORESET#0定义的第一下行带宽部分确定第一控制资源集合的频域位置。
对于终端设备而言，在终端设备初始接入成功之前，可以在SIB 1消息中获得第一控制资源集合的配置信息，对于网络设备而言，在终端设备初始接入成功之前，可以在SIB 1消息中携带第一控制资源集合的配置信息。终端设备和网络设备可以根据CORESET#0的 第二起始公共资源块确定第一控制资源集合的第一起始公共资源位置，在终端设备初始接入成功之后，终端设备根据图10所示的第一控制资源集合监听下行物理控制信道以获得上下行调度控制信息，网络设备根据图10所示的第一控制资源集合在下行物理控制信道发送上下行调度控制信息。这一方式所确定第一控制资源集合的频域位置是相同的，终端设备和网络设备只需要计算一次第一控制资源集合的位置，降低了确定第一控制资源集合的频域位置复杂度。
本申请实施例对第一控制资源集合的频域位置的确定时刻不做限定，可以在终端设备初始接入成功之前根据该配置信息和CORESET#0定义的第一下行带宽部分的频域位置确定第一控制资源集合的频域位置，或者可以在终端设备初始接入成功之后根据该配置信息和CORESET#0定义的第一下行带宽部分的频域位置确定第一控制资源集合的频域位置。
在第B2种情况中，请参见图11，为本申请实施例提供了另一种控制资源集合的频域位置的示例图。在图11中，第一下行带宽部分是由SIB 1配置的initial DL BWP,第一控制资源集合的第一起始公共资源块是根据SIB 1配置的第一下行带宽部分的第二起始公共资源块和第一控制资源集合的配置信息确定的。具体的，在确定SIB 1配置的第一下行带宽部分的第二起始公共资源块之后，确定第一控制资源集合的第一起始公共资源块的详细过程可以参见图6的详细介绍，其中，第五偏移是指SIB 1配置的第一下行带宽部分的第二起始公共资源块与第一控制资源集合的第一起始公共资源块相差的公共资源块的数量。
其中，在第一下行带宽部分为根据SIB 1配置的情况下，第一下行带宽部分的第二起始公共资源块是根据第一下行带宽部分的第二起始物理资源块和第三偏移确定的；其中，第三偏移用于指示第二起始物理资源块与参考点之间相差的物理资源块的数量，参考点是资源块网格的一个公共参考点，参考点用于指示以预设子载波间隔配置的公共资源块CRB 0中的子载波0的中心位置。如图11所示，公共参考点可以为参考点A(point A)的位置，指示的是公共资源块CRB 0中的子载波0的中心位置。这里仅简单介绍了SIB 1配置的第一下行带宽部分的第二起始公共资源块的确定方式，详细的介绍，请参见图8的详细描述。
基于第B2种情况，可选的，在实际应用中可以只有一种配置第一下行带宽部分的方式，在该情况中是通过SIB 1来配置的。或者，可选的，在实际应用中可以通过CORESET#0和SIB 1配置第一下行带宽部分，在这一情况下，选择以SIB 1配置的第一下行带宽部分确定第一控制资源集合的频域位置。
对于终端设备而言，在终端设备初始接入成功之前，可以在SIB 1消息中获得第一控制资源集合的配置信息，对于网络设备而言，在终端设备初始接入成功之前，可以在SIB 1消息中携带第一控制资源集合的配置信息。终端设备和网络设备可以根据SIB 1配置的第一下行带宽部分的第二起始公共资源块确定第一控制资源集合的第一起始公共资源位置，在终端设备初始接入成功之后，终端设备根据图11所示的第一控制资源集合监听下行物理控制信道以获得上下行调度控制信息，网络设备根据图11所示的第一控制资源集合在下行物理控制信道发送上下行调度控制信息。这一方式所确定第一控制资源集合的频域位置是相同的，终端设备和网络设备只需要计算一次第一控制资源集合的位置，降低了确定第一控制资源集合的频域位置复杂度。
本申请实施例对第一控制资源集合的频域位置的确定时刻不做限定，可以在终端设备 初始接入成功之前根据该配置信息和SIB 1配置的第一下行带宽部分的频域位置确定第一控制资源集合的频域位置，或者可以在终端设备初始接入成功之后根据该配置信息和SIB 1配置的第一下行带宽部分的频域位置确定第一控制资源集合的频域位置。
其中，图9、图10和图11中时刻T表示终端设备初始接入成功的时刻。网络设备和终端设备对于时刻T的认定可能不同。在可选的实现方式中，对于终端设备而言，终端设备确定初始接入成功的时刻用于指示以下(10-1)、(10-2)、(10-3)、(10-4)、(10-5)、(10-6)的其中一个时刻：
(10-1)终端设备成功接收初传的消息4并向网络设备发送确认消息的时刻；

在本申请实施例中，在终端设备初始接入成功之前，网络设备不会根据所述第一控制资源集合占用的公共资源块集合在下行物理控制信道上发送上下行调度控制信息，终端设备不会根据第一控制资源集合的频域位置监听下行物理控制信道，这样在终端设备初始接入成功之前网络设备和终端设备均无需确定第一控制资源集合的频域位置，在终端设备初始接入之后的第一控制资源集合的频域位置是以所参考的下行带宽部分来确定，这样终端设备和网络设备仅需要计算一次第一控制资源集合的频域位置，降低了确定第一控制资源集合的频域位的复杂度。
基于图1所示的通信系统，请参见图12，为本申请实施例提供了另一种用于确定控制资源集合的频域位置的方法的流程示意图。图12所示的方法包括步骤1201至步骤1203。

1203，在终端设备初始接入成功之后，网络设备根据第一控制资源集合占用的第三公共资源块集合，在下行物理控制信道上发送上下行调度控制信息。
相应的，在终端设备初始接入成功之后，终端设备根据第一控制资源集合占用的第三公共资源块集合，监听下行物理控制信道以获得上下行调度控制信息。
其中，在步骤1202中，所述第一公共资源块集合包含的第一起始公共资源块是根据第一下行带宽部分的第二起始公共资源块和所述第一控制资源集合的配置信息确定的，所述配置信息用于指示所述第一控制资源集合在所述第一下行带宽部分内占用的物理资源块的位置。这里的第一下行带宽部分可以是由CORESET#0定义的。
在步骤1203中，所述第三公共资源块集合包含的第三起始公共资源块是根据第二下行带宽部分的第四起始公共资源块和所述第一控制资源集合的配置信息确定的，所述配置信息用于指示所述第一控制资源集合在所述第二下行带宽部分内占用的物理资源块的位置。这里的第二下行带宽部分可以是SIB 1配置的。
在图12所示的实施例中，所述第一下行带宽部分的所述第二起始公共资源块与所述第二下行带宽部分的所述第四起始公共资源块相同。这样虽然在终端设备初始接入成功前后第一控制资源集合所参考的下行带宽部分不同，通过设定这两个下行带宽部分的起始公共资源块相同，依旧可以使得根据第一下行带宽部分确定第一控制资源集合的第一起始公共资源块，与根据第二下行带宽部分确定的第二控制资源集合的第三起始公共资源块是相同的。
本申请的第一控制资源集合的标识不为0。
可选的，第一控制资源集合的配置信息可以从SIB 1中获得，且该配置信息在终端设备初始接入成功之前或后均可以生效，这里的生效是指：终端设备可以根据第一控制资源集合的频域位置监听下行物理控制信道以获得上下行调度控制信息；或者，网络设备可以根据第一控制资源集合的频域位置在下行物理控制信道发送上下行调度控制信息。
可选的，在包含第一下行带宽部分是由SIB 1配置的initial DL BWP的场景中，第一下行带宽部分的配置信息也可以从SIB 1中获得，但SIB 1配置的第一下行带宽部分的配置信息是在终端设备初始接入成功之后生效，这里的生效是指：终端设备可以利用第一下行带宽部分的一个高层信令locationAndBandwidth和/或其他参数确定第一下行带宽部分的频域位置，并可以根据SIB 1配置的第一下行带宽部分的频域位置接收下行控制信息，或者，网络设备可以根据SIB 1配置的第一下行带宽部分的频域位置发送下行控制信息。
在终端设备初始接入成功之前，第一控制资源集合占用的第一公共资源块包括第一起始公共资源块和第一控制资源集合占用的其他公共资源块，在终端设备初始接入成功之后，第一控制资源集合占用的第三公共资源块包括第三起始公共资源块和第一控制资源集合占 用的其他公共资源块。在本申请实施例中，网络设备和终端设备均可以实现确定第一起始公共资源块与第三起始公共资源块，以及均可以实现根据配置信息和所参考的下行带宽部分的起始公共资源块确定第一控制资源集合占用的由第一起始公共资源块起始的公共资源块，以及均可以实现根据配置信息和所参考的下行带宽部分的起始公共资源块确定第一控制资源集合占用的由第三起始公共资源块起始的公共资源块。对于如何确定第一起始公共资源块、第三起始公共资源块可以参见图13的详细介绍。
请参见图13，为本申请实施例提供了另一种控制资源集合的频域位置的示例图。在图13中，第一下行带宽部分是由CORESET#0定义的initial DL BWP，第一控制资源集合1的第一起始公共资源块是根据CORESET#0的第二起始公共资源块和第一控制资源集合的配置信息确定的。第二下行带宽部分是由SIB 1配置的initial DL BWP，第一控制资源集合2的第三起始公共资源块是根据SIB1配置的initial DL BWP的第四起始公共资源块和第一控制资源集合的配置信息确定的。所述第一下行带宽部分的所述第二起始公共资源块与所述第二下行带宽部分的所述第四起始公共资源块相同。
具体的，在确定CORESET#0的第二起始公共资源块之后，确定第一控制资源集合1的第一起始公共资源块的详细过程可以参见图6的详细介绍。以及在确定SIB1配置的initial DL BWP的第四起始公共资源块之后，确定第一控制资源集合2的第三起始公共资源块的详细过程可以参见图6的详细介绍，其中，第四偏移是指CORESET#0的第二起始公共资源块与第一控制资源集合的第一起始公共资源块相差的公共资源块的数量。
其中，CORESET#0的第二起始公共资源块是指CORESET#0占用的最小CRB；第一控制资源集合的第一起始公共资源块是指第一控制资源集合占用的最小CRB。CORESET#0的第二起始公共资源块是根据CORESET#0的第二起始物理资源块和第一偏移确定的，第一偏移用于指示第二起始物理资源块与参考点之间相差的物理资源块的数量，参考点是资源块网格的一个公共参考点，参考点用于指示以预设子载波间隔配置的公共资源块CRB 0中的子载波0的中心位置。如图4所示，公共参考点可以为参考点A(point A)的位置，指示的是公共资源块CRB 0中的子载波0的中心位置。
第一偏移是根据CORESET#0的第二起始物理资源块与SS/PBCH block的第三起始物理资源块之间的第二偏移和SS/PBCH block的公共资源块偏移确定的。其中，第二偏移用于指示第二起始物理资源块与SS/PBCH block的第三起始物理资源块之间相差的物理资源块数量；SS/PBCH block的公共资源块偏移用于指示第三起始物理资源块与参考点之间相差的物理资源块的数量，如图10所示的相对于参考点A的偏移

这样第一偏移等于
Figure PCTCN2019128916-appb-000008
减去第二偏移的值。
这里仅简单介绍了CORESET#0的第二起始公共资源块的确定方式，进一步可以请参见图8的详细描述。
其中，在第二下行带宽部分为根据SIB 1配置的情况下，第二下行带宽部分(图13中的SIB1配置的initial DL BWP)的第四起始公共资源块是根据第二下行带宽部分的第四起始物理资源块和第三偏移确定的；其中，第三偏移用于指示第四起始物理资源块与参考点之间相差的物理资源块的数量，参考点是图13中参考点A(point A)的位置。这里仅简单介绍了SIB 1配置的第二下行带宽部分的第四起始公共资源块的确定方式，详细的介绍， 请参见图8的详细描述。
对于终端设备而言，在终端设备初始接入成功之前，可以在SIB 1消息中获得第一控制资源集合的配置信息，对于网络设备而言，在终端设备初始接入成功之前，可以在SIB 1消息中携带第一控制资源集合的配置信息。终端设备和网络设备可以根据CORESET#0的第二起始公共资源块确定第一控制资源集合1的第一起始公共资源位置，以及可以根据SIB 1配置的initial DL BWP的第四起始公共资源块确定第一控制资源集合2的第三起始公共资源位置。
在终端设备初始接入成功之前，终端设备根据图13所示的第一控制资源集合1监听下行物理控制信道以获得上下行调度控制信息，网络设备根据图13所示的第一控制资源集合1在下行物理控制信道发送上下行调度控制信息。在终端设备初始接入成功之后，终端设备根据图13所示的第一控制资源集合2监听下行物理控制信道以获得上下行调度控制信息，网络设备根据图13所示的第一控制资源集合2在下行物理控制信道发送上下行调度控制信息。这一方式所确定第一控制资源集合的频域位置是相同的，终端设备和网络设备只需要计算一次第一控制资源集合的位置，降低了确定第一控制资源集合的频域位置复杂度。
本申请实施例对第一控制资源集合的频域位置的确定时刻不做限定，例如，第一控制资源集合的频域位置在第一控制资源集合1或第一控制资源集合2上监听/发送之前确定即可，本申请实施例对此不做限定。
其中，图12和图13中时刻T表示终端设备初始接入成功的时刻。网络设备和终端设备对于时刻T的认定可能不同。在可选的实现方式中，对于终端设备而言，终端设备确定初始接入成功的时刻用于指示以下(13-1)、(13-2)、(13-3)、(13-4)、(13-5)、(13-6)、(13-7)、(13-8)、(13-9)、(13-10)的其中一个时刻：
(13-1)终端设备成功接收初传的消息4并向网络设备发送确认消息的时刻；

(13-4)终端设备在终端设备成功接收重传的消息4之后，终端设备成功接收到由小区无线网络临时标识C-RNTI加扰的下行控制信息DCI的时刻；
(13-5)在第一下行带宽部分和第二下行带宽部分所占用的公共资源块不同的情况下，终端设备成功接收初传的消息4并向网络设备发送确认消息之后，由第一下行带宽部分切换至第二下行带宽部分的切换完成时刻；
(13-6)在第一下行带宽部分和第二下行带宽部分所占用的公共资源块不同的情况下，终端设备成功接收重传的消息4并向网络设备发送确认消息之后，由第一下行带宽部分切换至第二下行带宽部分的切换完成时刻；
(13-7)在第一下行带宽部分和第二下行带宽部分所占用的公共资源块不同的情况下，在终端设备成功接收初传的消息4且由第一下行带宽部分切换至第二下行带宽部分之后，终端设备成功接收到由小区无线网络临时标识C-RNTI加扰的下行控制信息DCI的时刻；
(13-8)在第一下行带宽部分和第二下行带宽部分所占用的公共资源块不同的情况下， 在终端设备成功接收重传的消息4且由第一下行带宽部分切换至第二下行带宽部分之后，终端设备成功接收到由小区无线网络临时标识C-RNTI加扰的下行控制信息DCI的时刻；
(13-9)在第一下行带宽部分和第二下行带宽部分所占用的公共资源块不同的情况下，在终端设备成功接收初传的消息4且由第一下行带宽部分切换至第二下行带宽部分之后，终端设备成功接收到用于指示需盲检C-RNTI加扰的DCI的配置信息的时刻；
(13-10)在第一下行带宽部分和第二下行带宽部分所占用的公共资源块不同的情况下，在终端设备成功接收初传的消息4且由第一下行带宽部分切换至第二下行带宽部分之后，终端设备成功接收到用于指示需盲检C-RNTI加扰的DCI的配置信息的时刻。
对于网络设备而言，网络设备确定初始接入成功的时刻用于指示以下(13-11)、(13-12)、(13-13)、(13-14)的其中一个时刻：
(13-11)网络设备接收到终端设备发送的针对网络设备发送的初传消息4的确认消息的时刻；
(13-12)网络设备接收到终端设备发送的针对网络设备发送的重传消息4的确认消息的时刻；
(13-13)网络设备接收到终端设备发送的针对网络设备发送的初传消息4的确认消息之后，向终端设备发送用于指示需盲检C-RNTI加扰的DCI的配置信息的时刻；
(13-14)网络设备接收到终端设备发送的针对网络设备发送的重传消息4的确认消息之后，向终端设备发送用于指示需盲检C-RNTI加扰的DCI的配置信息的时刻；
(13-15)在第一下行带宽部分和第二下行带宽部分所占用的公共资源块不同的情况下，网络设备接收到终端设备发送的针对网络设备发送的初传消息4的确认消息之后，由第一下行带宽部分切换至第二下行带宽部分的切换完成时刻；
(13-16)在第一下行带宽部分和第二下行带宽部分所占用的公共资源块不同的情况下，网络设备接收到终端设备发送的针对网络设备发送的重传消息4的确认消息之后，由第一下行带宽部分切换至第二下行带宽部分的切换完成时刻；
(13-17)在第一下行带宽部分和第二下行带宽部分所占用的公共资源块不同的情况下，网络设备接收到终端设备发送的针对网络设备发送的初传消息4的确认消息且由第一下行带宽部分切换至第二下行带宽部分之后，向终端设备发送用于指示需盲检C-RNTI加扰的DCI的配置信息的时刻；
(13-18)在第一下行带宽部分和第二下行带宽部分所占用的公共资源块不同的情况下，网络设备接收到终端设备发送的针对网络设备发送的重传消息4的确认消息且由第一下行带宽部分切换至第二下行带宽部分之后，向终端设备发送用于指示需盲检C-RNTI加扰的DCI的配置信息的时刻。
在本申请实施例中，在终端设备初始接入成功之前和之后，第一控制资源集合的频域位置可以依据不同的下行带宽部分的频域位置来确定，但由于设定不同下行带宽部分的起始公共资源块位置是相同的，依旧可以使得以不同的下行带宽部分为参考的第一控制资源集合的频域位置是相同的，这样终端设备和网络设备仅需要计算一次第一控制资源集合的频域位置，降低了确定第一控制资源集合的频域位的复杂度。
基于图1所示的通信系统，请参见图14，为本申请实施例提供了另一种用于确定控制资源集合的频域位置的方法的流程示意图。图14所示的方法包括步骤1401和步骤1402。
1401，在终端设备初始接入成功之后，网络设备向所述终端设备发送第一控制资源集合的配置信息。
相应的，在终端设备初始接入成功之后，终端设备接收第一控制资源集合的配置信息。
1402，在所述终端设备初始接入成功之后，所述网络设备根据所述第一控制资源集合占用的第一公共资源块集合，在下行物理控制信道上发送上下行调度控制信息。
相应的，在终端设备初始接入成功之后，终端设备根据第一控制资源集合占用的第一公共资源块集合，监听下行物理控制信道以获得上下行调度控制信息。
其中，配置信息用于指示第一控制资源集合在第一下行带宽部分内占用的物理资源块的位置。本申请的第一控制资源集合的标识不为0。
其中，在终端设备初始接入成功之前，不会配置第一控制资源集合的配置信息。在终端设备初始接入成功之后，才会配置第一控制资源集合的配置信息。在终端设备初始接入成功之后，终端设备可以根据第一控制资源集合占用的公共资源块集合监听下行物理控制信道。而且第一控制资源集合的频域位置是以一个下行带宽部分为参考来确定的，具体可以参见图15的具体介绍。
可选的，第一控制资源集合的配置信息可以在终端设备初始接入成功之后从SIB 1中获得，且该配置信息在终端设备初始接入成功之后可以生效，这里的生效是指：终端设备可以根据第一控制资源集合的频域位置监听下行物理控制信道以获得上下行调度控制信息；或者，网络设备可以根据第一控制资源集合的频域位置在下行物理控制信道发送上下行调度控制信息。
或者，可选的，第一控制资源集合的配置信息可以在终端设备初始接入成功之后从其他配置下行带宽部分的消息来配置的，图14所示实施例对此不做限定。
进一步，可选的，图14所示实施例中，所述第一控制资源集合的配置信息与所述第一下行带宽部分的配置信息是同时接收到的，第一控制资源集合的配置信息是包含在第一下行带宽部分的配置信息中的，第一控制资源集合的频域位置的确定是根据包含第一控制资源集合的配置信息的第一下定带宽为参考的。也就是说，在终端设备初始接入成功之后，在一个配置消息中可以同时获得第一控制资源集合的配置信息与所述第一下行带宽部分的配置信息。第一控制资源集合的频域位置是根据第一下行带宽部分和第一控制资源集合的配置信息确定的。
第一控制资源集合占用的第一公共资源块包括第一起始公共资源块和第一控制资源集合占用的其他公共资源块。在本申请实施例中，网络设备和终端设备均可以实现确定第一起始公共资源块，以及均可以实现根据配置信息和所参考的下行带宽部分的起始公共资源块确定第一控制资源集合占用的由第一起始公共资源块起始的公共资源块。对于如何确定第一起始公共资源块可以参见图15的具体介绍。
请参见图15，为本申请实施例提供了另一种控制资源集合的频域位置的示例图。在图15中，第一下行带宽部分是由SIB 1或者其他配置消息来配置的，第一控制资源集合的第一起始公共资源块是根据第一下行带宽部分的第二起始公共资源块和第一控制资源集合的 配置信息确定的。具体的，在确定第一下行带宽部分的第二起始公共资源块之后，确定第一起始公共资源块的详细过程可以参见图6的详细介绍，其中，第五偏移是指SIB 1或者其他配置消息配置的第一下行带宽部分的第二起始公共资源块与第一控制资源集合的第一起始公共资源块相差的公共资源块的数量。
其中，第一下行带宽部分的第二起始公共资源块是根据第一下行带宽部分的第二起始物理资源块和第三偏移确定的；其中，第三偏移用于指示第二起始物理资源块与参考点之间相差的物理资源块的数量，参考点是资源块网格的一个公共参考点，参考点用于指示以预设子载波间隔配置的公共资源块CRB 0中的子载波0的中心位置。如图15所示，公共参考点可以为参考点A(point A)的位置，指示的是公共资源块CRB 0中的子载波0的中心位置。这里仅简单介绍了第一下行带宽部分的第二起始公共资源块的确定方式，详细的介绍，请参见图8的详细描述。
可选的，在实际应用中可以只有一种配置第一下行带宽部分的方式。或者，可选的，在实际应用中可以通过CORESET#0和其他配置消息来配置第一下行带宽部分，在这一情况下，选择在终端设备初始接入成功之后配置的第一下行带宽部分确定第一控制资源集合的频域位置。
对于终端设备而言，在终端设备初始接入成功之后，可以在配置消息中获得第一控制资源集合的配置信息，对于网络设备而言，在终端设备初始接入成功之后，可以在配置消息中携带第一控制资源集合的配置信息。终端设备和网络设备可以根据配置消息中的第一下行带宽部分的第二起始公共资源块确定第一控制资源集合的第一起始公共资源位置，在终端设备初始接入成功之后，终端设备根据图15所示的第一控制资源集合监听下行物理控制信道以获得上下行调度控制信息，网络设备根据图15所示的第一控制资源集合在下行物理控制信道发送上下行调度控制信息。这一方式所确定第一控制资源集合的频域位置是相同的，终端设备和网络设备只需要计算一次第一控制资源集合的位置，降低了确定第一控制资源集合的频域位置复杂度。
其中，图14、图15中时刻T表示终端设备初始接入成功的时刻。网络设备和终端设备对于时刻T的认定可能不同。在可选的实现方式中，对于终端设备而言，终端设备确定初始接入成功的时刻用于指示以下(15-1)、(15-2)、(15-3)、(15-4)、(15-5)、(15-6)的其中一个时刻：
(15-1)终端设备成功接收初传的消息4并向网络设备发送确认消息的时刻；
(15-2)在终端设备成功接收初传的消息4之后，终端设备成功接收到由小区无线网络临时标识C-RNTI加扰的下行控制信息DCI的时刻；
(15-3)终端设备成功接收重传的消息4并向网络设备发送确认消息的时刻；
(15-4)终端设备在终端设备成功接收重传的消息4之后，终端设备成功接收到由小区无线网络临时标识C-RNTI加扰的下行控制信息DCI的时刻；
(15-5)终端设备成功接收初传的消息4之后成功接收到用于指示需盲检C-RNTI加扰的DCI的配置信息的时刻；
(15-6)终端设备成功接收重传的消息4之后成功接收到用于指示需盲检C-RNTI加扰的DCI的配置信息的时刻。
对于网络设备而言，网络设备确定初始接入成功的时刻用于指示以下(15-7)、(15-8)、(15-9)、(15-10)的其中一个时刻：
(15-7)网络设备接收到终端设备发送的针对网络设备发送的初传消息4的确认消息的时刻；
(15-8)网络设备接收到终端设备发送的针对网络设备发送的重传消息4的确认消息的时刻；
(15-9)网络设备接收到终端设备发送的针对网络设备发送的初传消息4的确认消息之后，向终端设备发送用于指示需盲检C-RNTI加扰的DCI的配置信息的时刻；
(15-10)网络设备接收到终端设备发送的针对网络设备发送的重传消息4的确认消息之后，向终端设备发送用于指示需盲检C-RNTI加扰的DCI的配置信息的时刻。
在本申请实施例中，在终端设备初始接入成功之前，网络设备不会根据所述第一控制资源集合占用的公共资源块集合在下行物理控制信道上发送上下行调度控制信息，终端设备不会根据第一控制资源集合的频域位置监听下行物理控制信道，这样在终端设备初始接入成功之前网络设备和终端设备均无需确定第一控制资源集合的频域位置，在终端设备初始接入之后的第一控制资源集合的频域位置是以所参考的下行带宽部分来确定，这样终端设备和网络设备仅需要计算一次第一控制资源集合的频域位置，降低了确定第一控制资源集合的频域位的复杂度。
针对图3至图15所示的方法实施例，需要说明的是，在实际应用中，在第一种可能的实现方式中，不限制网络设备配置第一控制资源集合的时刻。也就是说，第一控制资源集合的配置消息可以在终端设备初始接入成功之前配置，也可以在终端设备初始接入成功之后配置。在这一场景下，可以包含图3至图15描述的各种可实现方案。
举例来说，由于网络设备配置第一控制资源集合的时刻不确定，因此，终端设备可以在初始接入之前监听信道以获得第一控制资源集合的配置信息；在终端设备获得第一控制资源集合的配置信息或者没有获得第一控制资源集合的配置信息的情况下，终端设备均可以在初始接入之后可以监听信道以获得第一控制资源集合的配置信息。
基于第一种可能的实现方式，进一步的，可以不限制配置第一控制资源集合所参考的下行带宽部分的时刻，这一场景中，若网络设备配置了新的下行带宽部分，在终端设备接收到新的下行带宽部分的配置信息的情况下，可以参考新的下行带宽部分的频域位置来确定第一控制资源集合的位置。
在第二种可能的实现方案中，可以限制网络设备配置第一控制资源集合的时刻。例如，限制第一控制资源集合的配置消息可以在终端设备初始接入成功之后配置，在这一场景下，可以参考图14和图15描述的实现方案。举例来说，由于网络设备配置第一控制资源集合的时刻是在终端设备初始接入成功之后，因此，终端设备在初始接入之前不需要监听信道，而是在终端设备初始接入成功之后，终端设备开始监听信道以获得第一控制资源集合的配置信息。这样可以减少终端设备由于不确定监听带来的功率损耗。
基于第二种可能的实现方式，进一步的，可以限制配置第一控制资源集合所参考的下行带宽部分的时刻，这一场景中，若限制下行带宽部分的配置时刻是在终端设备初始接入 成功之后，则一旦网络设备配置了新的下行带宽部分，在终端设备接收到新的下行带宽部分的配置信息的情况下，可以参考新的下行带宽部分的频域位置来确定第一控制资源集合的位置。
在另一种可能的实现方式中，不管第一控制资源集合在终端设备初始接入成功之前还是在终端设备初始接入成功之后配置，不管SIB 1中是否配置了initial DL BWP，在终端设备初始接入成功之后，网络设备通过高层信令(例如RRC信令)给终端设备配置第一控制资源集合、新配置的initial DL BWP或者其他DL BWP(非initial DL BWP或BWP_ID不为0的BWP)中的至少一个：
如果第一控制资源集合的配置在新配置的initial DL BWP中，则第一控制资源集合的频域位置以CORESET#0参考或以新配置的initial DL BWP为参考。也就是说，在图3-图15所示的实施例中，在终端设备初始接入成功之后，网络设备通过高层信令(例如RRC信令)给终端设备配置新配置的initial DL BWP，且新配置的initial DL BWP与SIB1中配置的initial DL BWP的子载波间隔相同时，则第一控制资源集合的频域位置以CORESET#0参考或以新配置的initial DL BWP为参考。
如果在终端设备初始接入成功之前由SIB 1配置了initial DL BWP，且第一控制资源集合的配置在其他DL BWP中，包括以下(1)和(2)两种情况：
(1)若其他DL BWP的频域位置包含CORESET#0的频域位置或包含SIB 1配置的initial DL BWP的频域位置，且其他DL BWP与SIB1配置的initial DL BWP的子载波间隔相同时，则第一控制资源集合的频域位置按照初始接入成功之前所参考的下行带宽部分来参考。
(2)若其他DL BWP的频域位置不包含CORESET#0的频域位置或不包含SIB 1配置的initial DL BWP的频域位置或其他DL BWP的频域位置包含CORESET#0的频域位置或包含SIB 1配置的initial DL BWP的频域位置且其他DL BWP与SIB1配置的initial DL BWP的子载波间隔不相同时，则以其他DL BWP为参考。
又一需要说明的是，终端设备在成功接收到网络设备发送的消息时，反馈1个比特的消息对接收到的消息进行肯定/确认(Acknowledgement，ACK)或否定(Negative ACKnowledgment，NACK)。网络设备根据终端设备的反馈的是ACK(比特取值1)还是NACK消息(比特取值0)来决定是发送新的数据还是进行重传。本申请实施例中涉及发送某一个消息的时刻可以为开始发送这一个消息的时刻或者确认这一消息发送完成的时刻，本申请对此不做限定。举例来说，图3-图15实施例中设计的发送确认消息的时刻，可以是指发送确认消息的时刻或者确认这一确认消息发送完成的时刻。
又一需要说明的是，如果第一控制资源集合在SIB 1中配置，则第一控制资源集合的频域资源位置限制在CORESET#0的频域资源范围内，即小于或等于CORESET#0的频域资源大小。如果第一控制资源集合不在SIB 1中配置，而是在其他高层信令中配置(例如RRC信令)，则第一控制资源集合的频域资源位置可以在CORESET#0的频域资源范围内，也可以不在CORESET#0的频域资源范围内。
如果在第一下行带宽部分中配置了用于随机接入信道的搜索空间高层参数，当初始接入成功之后网络设备通过高层信令(例如RRC信令)给终端设备配置其他下行带宽部分的 频域资源范围包括第一下行带宽部分的频域资源范围，且其他下行带宽部分的子载波间隔与第一下行带宽部分的子载波间隔相同时，如果当前激活下行带宽部分中没有配置用于随机接入信道的搜索空间高层参数，网络设备可以通过高层信令(例如RRC信令)在其他下行带宽部分中给终端设备配置在第一下行带宽部分中配置的用于随机接入信道的搜索空间中监听对应的下行控制信息，例如RA-RNTI加扰的下行控制信息。所述当前激活下行带宽部分的标识取非零值。在这个过程中终端设备不需要更改射频带宽或切换载波中心频率。
