Description

一种确定初始带宽部分BWP的方法、装置及存储介质 技术领域
本申请涉及通信领域，尤其涉及一种确定初始带宽部分BWP的方法、装置及存储介质。
背景技术
新无线(new radio，NR)系统，是基于正交频分复用(orthogonal frequency division multiplexing，OFDM)的全新空口设计的第五代(the fifth-generation，5G)移动通信技术的标准，也是下一代非常重要的蜂窝移动技术基础。NR系统业务非常多样，可以包括面向增强型移动宽带(enhanced mobile broadband，eMBB)业务、超可靠低延时通信(ultra-reliability low-latency communication，URLLC)业务以及大规模机器通信(massive machine-type communication，mMTC)业务。
NR系统业务的多样化，需要NR系统设计可以满足不同带宽能力终端设备的接入需求。例如，传输eMBB业务的终端设备和传输URLLC业务的终端设备可以通过确定NR系统的宽带信息接入NR系统，而部分传输mMTC业务的终端设备由于设计成本、低功耗等方面的考虑，对于数据传输的工作带宽一般不会设计的很大，因此一般只通过低带宽接入。
NR系统带宽较大，至少为100MHz。而终端设备由于带宽能力不同，所支持的最大带宽也不同，某些终端设备可能只能支持80MHz、40MHz或者20MHz，甚至更小的带宽。因此，通常情况下，在NR中为了适应终端设备所支持的最大带宽的需求，引入了下行初始带宽部分(bandwidth part，BWP)的概念。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、 “第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
为便于理解本申请实施例，以图1和图2中示出的通信系统为例详细说明适用于本申请实施例的通信系统。图1和图2是适用于本申请实施例的无线通信系统的示意图。图1所示，该无线通信系统可以包括单个或多个网络设备，或者如图2所示，该无线通信系统可以包括单个或多个终端设备，本申请有时也将无线通信系统简称为通信系统。单个网络设备可以向单个或多个终端设备传输数据或控制信令。多个网络设备也可以同时为单个终端设备传输数据或控制信令。该无线通信系统可支持协作多点传输(coordinated multiple points transmission，CoMP)，即，多个小区或多个网络设备可以协同参与一个终端设备的数据传输或者联合接收一个终端设备发送的数据，或者多个小区或多个网络设备进行协作调度或者协作波束成型。其中，该多个小区可以属于相同的网络设备或者不同的网络设备，并且可以根据信道增益或路径损耗、接收信号强度、接收信号指令等来选择。
应理解图1或图2仅为便于理解，示意性地示出了网络设备和终端设备，但这不应对本申请构成任何限定，该无线通信系统中还可以包括更多或更少数量的网络设备，也可以包括更多数量的终端设备，与不同的终端设备通信的网络设备可以是相同的网络设备，也可以是不同的网络设备，与不同的终端设备通信的网络设备的数量可以相同，也可以不同，本申请包括但不限于此。
通常终端设备在接入一个无线通信系统时，例如终端设备接入长期演进(long term evolution，LTE)系统或者NR系统时，需要先和该无线通信系统下的网络设备同步，即先通过检测网络设备发送的同步信号(synchronizing signal)确定与网络设备数据传输的同步信息，包括时间同步和/或频率同步信息，再根据确定的同步信息，确定网络设备承载在PBCH中的广播信息，并根据需求进一步读取系统信息(system information，SI)，例如先读取系统信息块类型1(system information block type 1，SIB1)包括的系统信息，进而获得与网络设备数据传输必要的系统信息。SIB1中包括的信息例如可以是随机接入信道(random access cHannel，RACH)的配置信息或者其他系统消息SI对应的调度信息。需要说明的是，在不同的系统中，SIB1的名称可能不同，在这里，为了便于描述，将终端设备检测网络设备发送的PBCH之后，为了与网络设备进行数据传输，第一个检测的网络设备发送的系统消息都称为SIB1，例如在NR系统中，网络设备发送的剩余最小系统信息(remaining minimum system information，RMSI)也可以理解为SIB1，而对于LTE系统，满足上述特征的系统信息就是SIB1。
下面以NR系统为例，对终端设备接入无线系统进行具体的介绍。NR的系统带宽较大，至少为100MHz。而终端设备由于能力不同，所支持的最大带宽也不同，某些终端设备可能只能支持80MHz、40MHz或者20MHz，甚至更小的带宽。因此，通常情况下，在NR中为了 适应终端设备所支持的最大带宽的需求，引入了BWP的概念。具体的，目前通过为终端设备配置BWP，以适应终端设备能够支持的最大带宽。当前，处于无线资源控制(radio resource control，RRC)空闲态(idle state)或者非活跃态(inactive state)的终端设备，需要接收(system information，SI)，才能根据SI进入无线资源控制连接态(RRC-connected)。具体的，网络设备通过广播同步信号块(synchronous signal block，SSB)以便终端设备进行驻留。SSB中携带主同步信号(primary synchronization signal，PSS)、辅同步信号(secondary synchronization signal，SSS)和物理广播信道(physical broadcast channel，PBCH)。PBCH中携带主系统信息块(master information block，MIB)。MIB包括控制资源集合(control resource set，CORESET)0的配置信息(例如CORESET0的带宽大小、频域位置、时频资源等)、和SIB1的物理下行控制信道(physical downlink control channel，PDCCH)的配置信息(例如PDCCH的时域配置信息等)。终端设备在接收到MIB后，确定初始BWP(initial BWP)的带宽为CORESET0的带宽，然后在初始BWP上接收SIB1的调度信息，并根据SIB1的调度信息在初始BWP上接收SIB1。在目前的NR系统中，承载在PBCH中MIB包括信息pdcch-ConfigSIB1，该信息包括8比特，用来指示调度SIB1的CORESET的配置信息。在本申请中，为了简化描述，除非有特殊说明，下行初始BWP为终端设备处于空闲态或者非活跃态的初始BWP。在NR中，用于调度SIB1的CORESET0对应的频率资源位置及大小可以认为是终端设备处于空闲态或者非活跃态对应的下行初始带宽部分BWP。
目前，NR的系统设计主要考虑的是传输eMBB业务的终端设备和传输URLLC业务的终端设备，针对传输mMTC业务的终端设备，还没有做特别的设计。具体的，NR的系统设计主要考虑的是传输eMBB业务的终端设备和传输URLLC业务的终端设备的初始BWP的频率资源，以及传输eMBB业务的终端设备和传输URLLC业务的终端设备的CORESET0的时间资源，针对传输mMTC业务的终端设备的初始BWP的频率资源以及时域资源，还没有做特别的设计。此外，在某些场景下，NR通过PBCH通知的下行初始BWP带宽可能会大于部分传输mMTC业务的终端设备的带宽能力，因此导致部分传输mMTC业务的终端设备无法接入NR系统。
为了解决上述技术问题，本申请提供一种确定初始BWP的方法。
本申请涉及两种类型的终端设备，本文将这两种类型的终端设备称为第一类型终端设备和第二类型终端设备。第一类型终端设备和第二类型终端设备的能力不同。具体的，两种类型终端设备可以具备下述一项或者多项区别特征：
(1)带宽能力不同。例如第二类型终端设备最大可以支持在一个载波上同时使用带宽为100MHz的频率资源和网络设备进行数据传输，而第一类型终端设备最大可以支持在一个载波上同时使用带宽为20MHz或者10MHz或者5MHz的频率资源和网络设备进行数据传输。
(2)收发天线数不同。例如第二类型终端设备可以支持4收2发，或者4收1发。而第一类型终端设备最大支持2收1发，或者最大支持1收1发。即支持发送天线个数不同和/或接收天线个数不同的终端设备都可以看为不同类型的终端设备。
(3)上行最大发射功率不同。例如第二类型终端设备的上行最大发射功率可以为23dBm或者26dBm，而第一类型终端设备的上行最大发射功率只能为4dBm～20dBm中的一个值。
(4)协议版本不同，例如第二类型终端设备为NR Release 17的终端设备(或者，第一终端设备为NR Release 17以及NR Release 17之后版本的终端设备)，第一类型终端设备为NR Release 15和/或NR Release 16的终端设备。在本申请中，NR Release 16以及NR Release 16之前的终端设备还可以称为NR后向兼容(NR-Legacy)终端设备。
(5)支持的载波聚合能力不同，例如，第二类型终端设备可以支持载波聚合，而第一类型不支持载波聚合；又例如，两类终端设备都可以支持载波聚合，但是第二类型终端设备同时支持的载波聚合的最大个数大于第一类型终端设备同时支持的载波聚合的最大个数，例如第二类型终端设备可以最多同时支持5个载波或者32个载波的聚合，而第一类型终端设备最多同时支持2个载波的聚合。
(6)双工能力不同。例如，第二类型终端设备支持全双工FDD，或者第二类型终端设备既支持全双工FDD也支持半双工FDD，而第一类型终端设备仅支持半双工FDD。
(7)对数据的处理时间能力不同，对数据的处理时间能力强的终端设备可以认为是第二类型的终端设备，对数据的处理时间能力弱的终端设备可以认为是第一类型的终端设备。处理时间能力不同可以通过两类终端设备处理数据的最小时延之间的关系来表示，也可以通过两类终端设备处理数据的最大时延之间的关系来表示，或者也可以通过一类终端设备处理数据的最小时延与另外一类终端设备处理数据的最大时延之间的关系来表达。其中数据处理的时延又可以用如下至少一种方式表示：接收下行数据与发送对该下行数据的反馈之间的时延，发送上行数据与接收对该上行数据的反馈之间的时延，接收控制信息与根据该控制信息发送上行数据之间的时延。例如，一类终端设备接收下行数据与发送对该下行数据的反馈之间的最小时延小于另外一类终端设备接收下行数据与发送对该下行数据的反馈之间的最小时延，和/或，一类终端设备发送上行数据与接收对该上行数据的反馈之间的最小时延小于另外一类终端设备发送上行数据与接收对该上行数据的反馈之间的最小时延，和/或一类终端设备接收控制信息与根据该控制信息发送上行数据之间的最小时延小于另外一类终端设备接收控制信息与根据该控制信息发送上行数据之间的最小时延。
(8)处理能力不同。这里的终端设备处理能力可以包括以下至少一项：上行数据传输和/或下行数据传输所支持的混合自动重传请求(hybrid automatic repeat request，HARQ)进程个数，软缓存(soft buffer)大小，上行数据传输和/或下行数据传输所支持的最高正交振幅调制(quadrature amplitude modulation，QAM)等。其中，处理能力强的终端设备可以认为是第二类型的终端设备，处理能力弱的终端设备可以认为是第一类型的终端设备。
(9)上行数据传输峰值速率和/或下行数据传输峰值速率不同。
具体的，在本申请中，两种类型的终端设备中的第一类型终端设备为NR-light终端设备、第二类型终端设备为非NR-Light终端设备或者为兼具NR-light与非NR-Light功能的终端设备(例如，NR Release 15，和/或NR Release 16的终端设备，也可以是未来无线通信系统中演进的终端设备，不限于LTE终端设备、以及NR终端设备)，其中，NR-Light终端设备可以对应如上区别特征描述中能力较低的终端设备；或者，两种类型的终端设备可以同为NR-light终端设备，但是两种终端设备之间存在如上区别特征，同为NR-light 终端设备，一种终端设备在一个载波上的数据传输带宽最大可以为20MHz，另外一种终端设备在一个载波上的数据传输带宽最大为10MHz。此外，NR-light终端设备也可以理解为NR低能力(NR reduced capability，NR REDCAP)终端设备。
本申请将从三个方面对本申请提供的确定初始BWP的方法进行说明，第一方面为如何确定初始BWP的频率资源。第二方面为如何确定CORESET0的时间资源，第三方面为如何确定第一时间资源的周期。其中，关于第一方面如何确定BWP的频率资源，本申请具体给出三种BWP的频率资源的设计方式，第一种方式为：第一类型终端设备对应的第一初始BWP的频率资源包括于第二类型终端设备对应的第二初始BWP的频率资源内。第二种方式为：第一类型终端设备对应的第一初始BWP的频率资源与第二类型终端设备对应的第二初始BWP的频率资源之间无重叠。第三种方式为：第一类型终端设备对应的第一初始BWP的频率资源与同步信号块SSB的频率资源之间无重叠。其中，关于第二方面为如何确定CORESET0的时间资源，本申请具体给出三种设计方式，需要说明的，这三种时间资源的设计方式的任意一种设计方式都可以与上述的三种频率资源的设计方式中的任意一种设计方式结合应用。关于第三方面，本申请提供两种设计方式，需要说明的是，第三方面如何确定第一时间资源的周期可以和第二方面提供的三种时间资源的设计方式的任意一种设计方式结合应用。下面将对本申请实施例提供的一种确定初始BWP的方法进行具体的介绍。
需要说明的是，在本申请中，初始BWP可以理解为包括公共信息传输的BWP。其中公共信息传输可以包括以下至少一项：
(1)网络设备广播的系统信息System Information和/或调度该系统信息传输的控制信息。系统信息可以包括调度系统信息块类型1(system information block type 1，SIB1)或者其他系统信息(system information，SI)。
(2)网络设备广播的寻呼(paging)信息和/或调度该寻呼信息传输的控制信息。
(3)网络设备广播的随机接入响应(random access response，RAR)信息。
特别地，第一初始BWP中包括的公共信息对应第一类型终端设备，第二初始BWP中包括的公共信息对应第二类型终端设备，当第一类型终端设备与第二类型终端设备使用相关的公共信息时，也可以理解，第一初始BWP中包括的公共信息既对应第一类型终端设备也对应第二类型终端设备，或者，第二初始BWP中包括的公共信息既对应第一类型终端设备也对应第二类型终端设备。
在本申请中，一个BWP由频率上连续的资源块(resource block，RB)组成，其中一个RB包括12个子载波(subcarrier)，BWP的频率带宽不大于包括该BWP的载波对应的频率带宽。目前在NR系统中，在一个载波或者一个服务小区上，终端设备和网络设备之间的数据传输在一个激活的BWP内实现，网络设备可以为终端设备配置最多4个BWP。
更具体的，例如初始BWP理解为通过MIB通知的频率资源，例如通过MIB中包括的pdcch-ConfigSIB1通知的频率资源，或者在SIB1信息中配置的频率资源，这里SIB1信息包括调度SIB1传输的控制信息，和/或通过物理下行共享信道(physical downlink shared channel，PDSCH)传输的SIB1系统信息。
(一)第一种频率资源的设计方式
如图3所示，为本申请实施例提供的一种确定初始BWP的方法的示意图。
其中，横轴代表时间，纵轴代表频率。图中分别展示了SSB传输的时频资源范围，第一类型终端设备对应的时频资源范围以及第二类型终端设备对应的时频资源范围。这里，第一类型终端设备对应的时频资源范围可以理解为在该时频资源范围内，包括第一类型终端设备对应的数据传输，数据传输例如为对应于第一类型终端设备且通过物理下行控制信道(physical downlink control channel，PDCCH)传输的系统信息调度信息和/或通过PDSCH传输的系统信息。同理，第二类型终端设备对应的时频资源范围可以理解为在该时频资源范围内，包括第二类型终端设备对应的数据传输，数据传输例如为对应于第二类型终端设备且通过PDCCH传输的系统信息调度信息和/或通过PDSCH传输的系统信息。
在本种实施方式中，确定第一类型终端设备对应的第一初始BWP的频率资源，第一初始BWP的频率资源包括于第二类型终端设备对应的第二初始BWP的频率资源内，第一类型终端设备和第二类型终端设备的能力不同。本申请所指的包括于是指第二类型终端设备对应的第二初始BWP的频率资源范围涵盖第一类型终端设备对应的第一初始BWP的频率资源范围，以下对此进行详细说明。通过这种实施方式，可以实现低能力类型的终端设备对应的初始BWP频率资源包含于非低能力类型的终端设备对应的初始BWP频率资源，即使对于系统带宽比较小的网络设备而言，也可以同时支持不同类型终端设备的数据传输，实现多样化数据传输，例如可以同时支持eMBB业务和mMTC业务，进而增加网络部署竞争力。
在一个具体的实施方式中，第一初始BWP的频率资源是根据第一频率偏移量确定的，第一频率偏移量属于第一集合，第一集合为第二频率偏移量的集合。其中，第一频率偏移量为第一初始BWP的频率资源相对同步信号块SSB的频率资源的偏移量，第二频率偏移量为第二初始BWP的频率资源相对SSB的频率资源的偏移量。换句话说，第一初始BWP的频率资源与SSB的频率资源之间的频率偏移量所对应的集合，为第二初始BWP的频率资源SSB的频率资源之间的频率偏移量所对应的集合的子集。需要说明的是，第一频率偏移量对应的同步信号块可以为第一类型终端设备对应的SSB，也可以为第二类型终端设备对应的SSB，第二频率偏移量对应的SSB为第二类型终端设备对应的SSB。例如第二类型终端设备为非NR REDCAP终端设备，非NR REDCAP终端设备对应的SSB为Release 15 SSB，此时，第一频率偏移量对应的SSB也为Release 15 SSB。
可选的，第一频率偏移量的取值与系统带宽、第一频率偏移量对应的SSB传输对应的子载波间隔(sub-carrier spacing，SCS)以及初始BWP包括的数据传输对应的SCS有关，其中第一频率偏移量对应的SSB，表示用于确定第一频率偏移量时参考的SSB。初始BWP包括的数据传输对应的SCS，可以用初始BWP包括的公共信息传输对应的SCS来表示。需要说明的是，公共信息传输对应的SCS，可以用调度公共信息传输的控制信息对应的SCS表示，也可以用公共信息传输对应的SCS直接表示，这里，控制信息对应的SCS可以理解为网络设备传输该控制信息时所采用的SCS，对于公共信息传输对应的SCS也有相同说明，不作赘述。其中，调度公共信息传输的控制信息对应的SCS还可以用承载该控制信息的PDCCH SCS表示。可选地，这里的PDCCH SCS例如是承载SIB1调度信息的控制信道对应的SCS，或者是包括SIB1调度信息的类型0 PDCCH搜索空间集合(Type0-PDCCH search space  set)对应的SCS。这里，SIB1调度信息可以理解为调度SIB1传输的控制信息。为了简化描述，下述用PDCCH SCS表示初始BWP包括的数据传输对应的SCS为例进行说明。
目前，在5G NR系统中，SSB的子载波间隔(sub-carrier spacing，SCS)和初始BWP的SCS支持的组合包括：{SSB SCS，PDCCH SCS}＝{{15，15}，{15，30}，{30，15}，{30，30}，{120，60}，{120，120}，{240，60}，{240，120}}kHz。其中，{{15，15}，{15，30}，{30，15}，{30，30}}kHz的组合，是低于6GHz情况下可以使用的组合；{{120，60}，{120，120}，{240，60}，{240，120}}kHz的组合，是高于6GHz情况下可以使用的组合。下面以低于6GHz情况下可以使用的组合对第一种频率资源的设计方式进行说明。
在本申请提供的实施方式中，第一初始BWP的频率带宽可以为与第一类型终端设备带宽能力匹配的带宽，例如如果第一类型终端设备的带宽能力为5MHz，则第一初始BWP的频率带宽也为5MHz；又例如如果第一类型终端设备包括多种带宽能力，例如NR REDCAP终端设备包括带宽能力分别为5MHz、10MHz、20MHz的终端设备，则第一初始BWP的频率带宽可以根据不同的第一类型终端设备分别确定，也可以根据第一类型终端设备的最小带宽能力确定，如该例中的5MHz。第一初始BWP带宽还可以为其他值，本申请不作具体限定。第一初始BWP带宽(带宽能力)大小可以是预配置的，例如可以为5MHz，或者10MHz，用RB表示的话，例如可以为24个(resource block，RB)，或者为48个RB。在本发明中，一个RB由整数个连续的子载波组成，例如由12个连续的子载波组成；或者，第一初始BWP带宽是通过物理广播信道(physical broadcast channel，PBCH)中承载的主信息块(master information block，MIB)通知，或者也可以通过其他方式，只要确保第一类型终端设备能够支持该第一初始BWP的带宽即可，具体第一类型终端设备如何获取第一初始BWP的带宽，本申请不作具体限定，以下对此不再重复赘述。此外，在本申请中，第一初始BWP的带宽还可以用用包括Type0 PDCCH search space set的控制资源集合0(control resource set 0，CORESET0)的带宽描述，其中，在Type0 PDCCH search space set中，终端设备至少检测由系统信息无线网络临时标识(system information radio network temporary identity，SI-RNTI)加扰的控制信息。
分类一：当系统最小带宽为5MHz或者10MHz，{SSB SCS，PDCCH SCS}＝{15kHz，15kHz}时：
在分类一的场景下，第二频率偏移量的集合为{0，2，4，12，16，38}，其中{0，2，4，12，16，38}的单位对应的是RB。第一频率偏移量属于第一集合，第一集合为第二频率偏移量的集合，则第一频率偏移量为集合{0，2，4，12，16，38}中的任一项。需要说明的是，在实际应用场景中，第二类型终端设备只会确定一个第二频率偏移量，本申请所指的第一集合是指第二类型终端可能采用的频率偏移量的集合，以下对此不再重复赘述。下面给出此种分类场景下的几种具体的设计方式：
第一终端设备对应的第一初始BWP带宽为24个RB，第二初始BWP的带宽为48个RB，且第二频率偏移量为12或16时，第一频率偏移量为0或者4。
第一终端设备对应的第一初始BWP带宽为24个RB，第二初始BWP的带宽为96个RB且第二频率偏移量为38时，第一频率偏移量为2。
第一终端设备对应的第一初始BWP带宽为48个RB，第一频率偏移量为集合{12，16，38}中的任一项。
第一终端设备对应的第一初始BWP带宽为96个RB，第一频率偏移量为38。
需要说明的是，在本申请中，第一初始BWP的带宽为24个RB时，这里的RB对应的子载波间隔为初始BWP对应的子载波间隔，或者同前描述可以用PDCCH子载波间隔表示。在本申请中，PDCCH子载波间隔可以理解为初始BWP对应的子载波间隔。上述说明对于下述实施方式同样有效，即使第一类型终端设备对应的第一初始BWP带宽不为24个RB，以下不再重复赘述。
需要说明的是，在本申请中，一种频率资源A与另外一种频率资源B之间的频率偏移量可以用频率资源A的起始位置对应的RB位置与频率资源B的起始位置对应的RB位置之间的RB个数差来表示，也可以用频率资源A的结束位置对应的RB位置与频率资源B的结束位置对应的RB位置之间的RB个数差来表示，其中频率资源的起始位置对应的RB可以为该频率资源的最低频率或最高频率对应的RB，相应地，该频率资源的结束位置对应的RB可以为该频率资源的最高频率或最低频率对应的RB。在描述不同频率资源之间的频率偏移量时，不同频率资源的起始位置采用相同的度量方法，例如都采用频率资源的最低频率对应的RB，或者最高频率对应的RB来确定。
需要说明的是，在本申请中，不同频率资源对应的子载波间隔可以不同，也可以相同，不作限定。当不同频率资源对应的子载波间隔不同时，不同频率资源之间的频率偏移所对应的RB个数可以用其中任一一个频率资源的RB表示。
另外，需要说明的是，不同频率资源的RB边界可能有不对齐的情况。如图4中的a所示，频率资源A和频率资源B之间的频率偏移量不足一个RB，一个RB在频率上连续12个子载波，可以认为图4中的a所示的情况中频率资源A与频率资源B之间的频率偏移量为0个RB。如图4中的b所示，频率资源A和频率资源B之间的频率偏移量大于一个RB且不足两个RB，虽然不同频率资源的RB边界不对齐，可以认为图4中的b所示的情况中，频率资源A与频率资源B之间的频率偏移量为1个RB。上述说明对于本申请其他部分内容同样有效，以下不再重复赘述。
分类二：当系统最小带宽为5MHz或者10MHz，{SSB SCS，PDCCH SCS}＝{15kHz，30kHz}时：
在分类二的场景下第二频率偏移量的集合为{5，6，7，8，18，20}，其中，{5，6，7，8，18，20}的单位对应的是RB。第一频率偏移量属于第一集合，第一集合为第二频率偏移量的集合，则第一频率偏移量为集合，则第一频率偏移量为集合{5，6，7，8，18，20}中的任意一项。下面给出此种分类场景下的几种具体的设计方式：
第二初始BWP的带宽为48个RB且第二频率偏移量为18个RB时，第一频率偏移量为{5，6}中任一个。
第二初始BWP的带宽为48个RB，且第二频率偏移量为20个RB时，第一频率偏移量为{7，8}中的任一个。
第一终端设备对应的第一初始BWP带宽为48个RB，第一频率偏移量为集合{18，20} 中的任一项。
分类三：当系统最小带宽为5MHz或者10MHz，{SSB SCS，PDCCH SCS}＝{30kHz，15kHz}时：
在分类三的场景下，第二频率偏移量的集合为{2，6，28}，其中{2，6，28}的单位对应的是RB。第一频率偏移量属于第一集合，第一集合为第二频率偏移量的集合，则第一频率偏移量为集合{2，6，28}中的任一项。下面给出此种分类场景下的几种具体的设计方式：
第二初始BWP的带宽为96个RB，且第二频率偏移量为28个RB时，第一频率偏移量为2个RB。
第一类型终端设备对应的第一初始BWP带宽为96个RB，第一频率偏移量为28。
分类四：当系统最小带宽为5MHz或者10MHz，{SSB SCS，PDCCH SCS}＝{30kHz，30kHz}时：
在分类四的场景下，第二频率偏移量的集合为{0，1，2，3，4，12，17，16}，其中{0，1，2，3，4，12，17，16}的单位对应的是RB。第一频率偏移量属于第一集合，第一集合为第二频率偏移量的集合，则第一频率偏移量为集合{0，1，2，3，4，12，17，16}中的任一项。下面给出此种分类场景下的几种具体的设计方式：
第二初始BWP的带宽为48个RB，且第二频率偏移量分别为12、17、16时，第一频率偏移量分别为0、2、4。
第一类型终端设备对应的第一初始BWP带宽为48个RB，第一频率偏移量为集合{12，17，16}中的任一项。
分类五：当系统最小带宽为40MHz，{SSB SCS，PDCCH SCS}＝{30kHz，15kHz}时：在分类五的场景下，第二频率偏移量的集合为{4，0，56}，其中{4，0，56}的单位对应的是RB。第一频率偏移量属于第一集合，第一集合为第二频率偏移量的集合，则第一频率偏移量为集合{4，0，56}中的任一项。下面给出此种分类场景下的几种具体的设计方式：
第一类型终端设备对应的第一初始BWP带宽为96个RB，第一频率偏移量为{0，56}中的任一项。
分类六：当系统最小带宽为40MHz，{SSB SCS，PDCCH SCS}＝{30kHz，30kHz}时：
在分类六的场景下，第二频率偏移量的集合为{0，4，28}，其中{0，4，28}的单位对应的是RB。第一频率偏移量属于第一集合，第一集合为第二频率偏移量的集合，则第一频率偏移量为集合{0，4，28}中的任一项。下面给出此种分类场景下的几种具体的设计方式：
第一类型终端设备对应的第一初始BWP带宽为48个RB，第一频率偏移量集合为{0，28}中的任一项。
通过上述实施方式，不仅可以实现第一初始BWP的频率资源与第二初始BWP的频率资源之间的嵌套关系，节省系统为了支持多样化终端设备所需要的系统带宽，而且由于设计中参考了第二频率偏移量的不同取值确定了第一频率偏移量的具体值，而第二频率偏移量在设计上兼顾了不同系统带宽以及不同同步信号块的同步栅格等影响，因此根据第二频率偏移量的不同取值确定的第一频率偏移量的具体值可以继承第二频率偏移量设计的好处，且可以降低标准设计复杂度。
在一个具体的实施方式中，第一初始BWP的频率资源与第二初始BWP的频率资源之间的频率偏移量为0，或者第一初始BWP的频率资源与第二初始BWP的频率资源之间的频率偏移量为第二初始BWP的频率资源大小减去第一初始BWP的频率资源大小。换句话说，如图5中的a所示，第一初始BWP的频率资源的起始位置对应的RB位置与第二初始BWP的频率资源的起始位置对应的RB位置相同，或者如图5中的b所示，第一初始BWP的频率资源的结束位置对应的RB位置与第二初始BWP的频率资源的结束位置对应的RB位置相同。
需要说明的是，第一类型终端设备可以通过预配置的方式确定第一初始BWP的频率资源，第一类型终端设备也可以通过网络设备发送的指示信息，确定第一初始BWP的频率资源，该指示信息可以是用于配置第一初始BWP的频率资源，也可以是用于配置第二初始BWP的频率资源，下面将分别针对这几种情况进行说明。
需要说明的是，在第一种第一初始BWP的频率资源的设计方式中，第一初始BWP可以包括上行初始BWP和下行初始BWP，下面以下行初始BWP为例，对第一类型终端设备确定第一初始BWP的频率资源的方式进行具体的说明。
(1)通过预配置的方式确定第一初始BWP的频率资源。
在这种方式中，第一类型终端设备预先保存第一初始BWP的频率资源配置信息。第一类型终端设备接入无线系统，可以按照预配置信息确定第一初始BWP的频率资源配置信息。下面结合图6对这种实施方式进行介绍。上述在论述不同分类场景下，给出了几种具体的设计方式，如图6中所示，可以以表格形式呈现上述给出的几种具体的设计方式。示例性的，如图6中的a所示的表格，是分类一对应的场景中给出的几种具体的设计方式，如图6中的b所示的表格，是分类二对应的场景中给出的几种具体的设计方式。可以预先规定第一类型终端设备的配置信息，比如第一类型终端设备可以预先保存图6中所示的表格，当第一类型终端设备接入无线系统时，可以按照图6中所示的表格确定第一初始BWP的频率资源配置信息。
需要说明的是，第一类型终端设备可以只保存第一频率偏移量这一种配置信息，第一类型终端设备的带宽可以是预配置的。第一类型终端设备也可以只保存第一频率偏移量和第一类型终端设备的带宽，而不保存第二类型终端设备的带宽以及第二频率偏移量。
(2)第一类型终端设备通过网络设备发送的指示信息确定第一初始BWP的频率资源，该指示信息用于配置第一初始BWP的频率资源。
第一初始BWP的频率资源设计，或者说第一频率偏移量的大小为这种实施方式的发明点，至于网络设备如何发送指示信息，终端设备如何根据指示信息确定出第一初始BWP的频率资源，现有技术中的方案本方案均可以采用。
(3)第一类型终端设备通过网络设备发送的指示信息确定第一初始BWP的频率资源，该指示信息用于配置第二初始BWP的频率资源。
第一频率偏移量是根据来自网络设备的第一配置信息确定的，第一配置信息用于配置所述第二初始BWP的频率资源。上面在论述第一种频率资源的设计方式中，给出了第一类型终端设备对应的第一初始BWP的频率资源与第二类型终端设备对应的第二初始BWP的频率资源的关系，在本种实施方式中，网络设备发送的指示信息，用于配置第二初始BWP的 频率资源，第一类型终端设备根据该指示信息确定自身的第一初始BWP的频率资源，这种实施方式，网络设备无需再为第二类型终端设备额外发送指示信息，用于确定第一初始BWP的频率资源，可以节省网络设备发送控制信息的开销，实现网络设备的节能，同时使用这种方式，在现有技术的基础上改动少。下面给出几种具体的方式论述第一类型终端设备如何根据网络设备发送的指示信息确定第一初始BWP的频率资源。应当理解的是，除了下面论述的几种具体的实现方式，只要满足第一初始BWP的频率资源包括于第二类型终端设备对应的第二初始BWP的频率资源内的范围，第一类型终端设备根据指示信息确定第一初始BWP的频率资源的方式，都应当属于本申请的保护范围。
如图7所示，为本申请实施例提供的一种确定初始带宽部分BWP的方法的流程示意图。
本申请提供的一种确定初始带宽部分BWP的方法可以包括如下步骤：
701、第一类型终端设备接收网络设备发送的第一配置信息。
该第一配置信息是用于配置第二初始BWP的频率资源。
702、第一类型终端设备根据第一配置信息确定第一索引值。
比如该指示信息是MIB消息。MIB中的PDCCH-ConfigSIB1指示一个表格的索引(index)，比如，在分类一的场景下，即系统最小带宽为5MHz或者10MHz，{SSB SCS，PDCCH SCS}＝{15kHz，15kHz}，PDCCH-ConfigSIB1指示下面表1的index，表中最后一列偏移量(offset)就是第二偏移量。表1中包括RB的数目(number of RBs)，符号数目(number of symbols)，其中number of RBs用于指示第二初始BWP的带宽，number of symbols用于指示CORESET0在时间上占用的时间资源，需要说明的是，CORESET0在时间上占用的时间资源可以是周期出现的，这里的number of symbols表示在一个周期内CORESET0的时间资源，即在时间上占用的符号个数。表1中还可以包括SS/PBCH block和PDCCH CORESET复用模式(SS/PBCH block and CORESET multiplexing pattern)，因为与本申请关系不大，所以并未在表1中示出。
第一类型终端设备根据第一配置信息确定第一索引值，比如pdcch-ConfigSIB1对应值为7，即确定index为7，即第一索引值为7。表1：
Figure PCTCN2020073794-appb-000001
Figure PCTCN2020073794-appb-000002
703、第一类型终端设备确定M个索引值，M个索引值中的任意一个索引值指示的频率偏移量确定第一频率偏移量。
M为正整数。M个索引值和第一索引值用于指示第一集合中包括的频率偏移量，比如以表1为例，第一集合为{0，2，4，12，16，38}。M个索引值小于或等于第一索引值的索引值。第一类型终端设备根据M个索引值中的任意一个索引值指示的频率偏移量确定第一频率偏移量。举例说明，如果第一类型终端设备根据第一配置信息确定第一索引值为7，在上述表1中，索引值小于7的索引值为0到6，所以M为7，索引值0指示的频率偏移量为0，索引值1指示的频率偏移量为2，索引值2指示的频率偏移量为4，索引值3指示的频率偏移量为0，索引值4指示的频率偏移量为2，索引值5指示的频率偏移量为4，索引值6指示的频率偏移量为12，所以第一频率偏移量可能为{0,2,4,12}中的任意一项。
如图8所示，为本申请实施例提供的另一种确定初始带宽部分BWP的方法的流程示意图。
本申请提供的一种确定下行初始带宽部分BWP的方法可以包括如下步骤：
801、第一类型终端设备接收网络设备发送的第一配置信息。
802、第一类型终端设备根据第一配置信息确定第一索引值。
步骤801和步骤802可以参阅图7对应的实施例中的步骤701和702进行理解，此处不再重复赘述。
803、第一类型终端设备根据第二索引值确定第一频率偏移量，第二索引值为第一索引值对预设值取模后的值。
第一类型终端设备确定第二索引值，第二索引值为第一索引值对预设值取模后的值，第一索引值和第二索引值指示第一集合中包括的频率偏移量。
下面以分类一描述的场景为例，对这一实施方式举例说明。pdcch-ConfigSIB1对应值即为第一索引值，第一索引值对预设值取模。可选地，在这种实现方式下，预设值可以为第一索引值所在表格中包括的初始BWP带宽不大于第一类型终端设备对应的第一初始BWP带宽的总配置个数。
例如，在分类一对应的场景下，假设第一初始BWP带宽为24个RB。则如表1中所示，预设值可以为6(即对应索引值为0至5对应的所有配置信息)。第一类型终端设备可以根据取模的结果结合表格1，确定第一初始BWP的频率资源分布。例如第一索引值为9，9对6取模(9 mod 6)为3，则第一类型终端设备可以确定第一频率偏移量为索引值3在表1中对应的频率偏移量即为0。
在分类一对应的场景下，假设第一初始BWP带宽为不大于48个RB，则如表1中所示， 预设值可以为12(即对应索引值为0至11对应的所有配置)。第一类型终端设备可以根据取模的结果结合表格1，确定第一初始BWP的频率资源分布。例如第一索引值为13，13对12取模(13 mod 12)，得到1，则第一类型终端设备可以确定第一频率偏移量为索引值1在表1中对应的频率偏移量，即为2个RB。
在一个具体的实施方式中，第一频率偏移量是根据第一时频资源数确定的，第一时频资源数和第二时频资源数对应于第一集合中包括的频率偏移量，第一时频资源数为最接近第二时频资源数的时频资源数，第二时频资源数为第二类型终端设备的CORESET0对应的时频资源数。
下面以分类一描述的场景为例，对这一实施方式举例说明。第一类型终端设备根据pdcch-ConfigSIB1确定第二初始BWP包括的CORESET0对应的第二时频资源数为48个RB*1个OFDM符号，假设第一类型终端设备的带宽为24个RB，则通过表1，第一终端设备可以确定第一初始BWP包括的CORESET0对应的第一时频资源数为24个RB*2个OFDM符号时，第一时频资源数最接近第二时频资源数。结合表1，当初始BWP包括的CORESET0对应的时频资源数为24个RB*2个OFDM符号时，对应的频率偏移量(表中的offset)可以为0、2、4，此时第一频率偏移量可以为{0,2,4}中的任意一个值，可选地，例如可以预配置第一频率偏移量为{0,2,4}中最小索引值对应的频率偏移量或者为频率偏移量中的最小值，例如预配置第一频率偏移量为0。
又例如，第一类型终端设备根据pdcch-ConfigSIB1确定第二初始BWP包括的CORESET0对应的时频资源为48个RB*2个OFDM符号，或者对应的时频资源更多时，第一类型终端设备可以确定第一初始BWP包括的CORESET0对应的时频资源数为24个RB*3个OFDM符号。结合上表1，当第一初始BWP包括的CORESET0对应的时频资源数为24个RB*3个OFDM符号时，对应的频率偏移量为(表中的offset)可以为0、2、4，此时第一频率偏移量可以为{0,2,4,}中的任意一个值，例如，在一个具体的实施方式中，可以预配置第一频率偏移量为{0,2,4,}最小索引值对应的频率偏移量或者为频率偏移量中的最小值，例如欲配置第一频率偏移量为0。
(二)第二种频率资源的设计方式
如图9所示，为本申请实施例提供的一种确定初始BWP的方法的示意图。
第一类型终端设备确定所述第一类型终端设备对应的初始BWP的频率资源，所述第一初始BWP的频率资源与所述第二初始BWP的频率资源之间无重叠，所述第一类型终端设备和所述第二类型终端设备的能力不同。
通过这种实施方式，由于第一初始BWP的频率资源与第二初始BWP的频率资源之间没有重叠，因此可以减小对第二类型终端设备数据传输的影响。对于系统带宽比较大的系统而言，通过这种实现方式，既可以实现对多样化数据业务的支持(例如同时支持eMBB业务和mMTC业务)，又不影响对已经部署的eMBB业务的影响。
在一个具体的实施方式中，第一初始BWP带宽可以预定义为第一类型终端设备的带宽，例如为5MHz。第一初始BWP频率资源与第二初始BWP频率资源之间的频率偏移量可以是预定义的，也可以通过其他方式实现，不作具体限定。例如，第一初始BWP频率资源与第二 初始BWP频率资源之间的频率偏移量为1个RB，这样既可以如上描述实现对多样化数据业务的支持，也可以实现同时支持多样化数据业务的系统带宽最小化。
需要说明的是，在第二种第一初始BWP的频率资源的设计方式中，第一初始BWP可以包括上行初始BWP和下行初始BWP。
(三)第三种频率资源的设计方式
如图10所示，为本申请实施例提供的一种确定初始BWP的方法的示意图。
第一类型终端设备确定所述第一类型终端设备对应的初始BWP的频率资源，所述第一初始BWP的频率资源与同步信号块SSB的频率资源之间无重叠，所述第一类型终端设备和所述第二类型终端设备的能力不同。
进一步可选地，在这种实现方式下，第一初始BWP的频率资源不仅与SSB的频率资源之间无重叠，而且还包括于第二初始BWP的频率资源之内。
通过这种实现方式，可以有效利用系统频率资源，尤其适用于系统带宽较小但又需要服务多样化业务的系统。
在一个具体的实施方式中，第一初始BWP的频率资源与SSB频率资源之间的频率偏移量可以是预定义的，第一初始BWP的带宽可以预定义为第一类型终端设备的带宽，例如为5MHz，也可以为其他值，不作具体限定。
需要说明的是，在本申请中，第一初始BWP的频率资源可以理解为包括第一初始BWP的频率资源位置，具体的可以通过第一初始BWP的频率起点和第一初始BWP的带宽，或者第一初始BWP的频率终点和第一初始BWP的带宽表示。对于第二初始BWP有相同的说明，本申请实施例中不作具体限定。
需要说明的是，对于NR载波频率大于6GHz的第一初始BWP频率资源确定方法也可以采用上述实现方式。
以上对本申请实施例提供的三种频率资源的设计方式进行了介绍，下面对如何确定CORESET0的时间资源进行介绍。
需要说明的是，在本申请实施例中，CORESET0除了可以如上理解为，还可以理解为包括调度信息传输的控制资源集合CORESET，其中该调度信息为用于调度初始BWP内包括的公共信息传输的控制信息。例如CORESET0为包括SIB1 PDCCH传输的时频资源集合、和/或为包括Paging PDCCH传输的时频资源集合、和/或为包括RAR PDCCH传输的时频资源集合。其中SIB1 PDCCH为承载调度SIB1传输的控制信息的物理下行控制信道，Paging PDCCH为承载调度Paging传输的控制信息的物理下行控制信道，RAR为承载调度RAR信息的物理下行控制信道。CORESET0的频率资源可以等价于初始BWP的频率资源，CORESET0的时间资源可以用与该CORESET0相关联的PDCCH搜索空间(search space，SS或者PDCCH搜索空间集合search space set出现的时间位置表示。这里，与该CORESET0相关联的PDCCH SS或者PDCCH搜索空间集合，可以理解为该CORESET0对应的频率资源内包括PDCCH SS或者PDCCH搜索空间集合配置，其中搜索空间集合可以理解为，包括一组终端设备需要检测的PDCCH备选的集合，在PDCCH备选上，终端设备可能检测到调度该终端设备数据传输的控制信息，也可能没有检测到，这取决于网络设备是否在该PDCCH备选上发送了调度该终端 设备数据传输的控制信息，这里的控制信息可以是小区特定的控制信息，也可以是终端设备特定的控制信息，在本申请实施例中不作具体限定。
更为具体的，CORESET0的时间资源例如可以理解为通过MIB中包括的pdcch-ConfigSIB1通知的时间资源，即Type0-PDCCH search space set对应的时间资源。
为了简化描述，下述均用CORESET0对应的时间资源描述。
(一)第一种CORESET0的时间资源的设计方式
在该实施方式下，第一初始BWP对应的CORESET0对应的时间资源
第一类型终端设备对应的第一CORESET0的时间资源所在的无线帧内不包括同步信号块SSB传输的时间资源，或者，第一时间资源所在的时隙(slot)内不包括第二类型终端设备对应的第二CORESET0的时间资源。
可选地，不同波束方向对应的第一时间资源优先在不包括SSB传输的时间资源的无线帧内映射，并按照与其关联的SSB索引，按照从小到大的顺序，依次映射在时隙索引按照从小到大顺序排列的时隙中，第一时间资源映射到的时隙中不包括第二CORESET0的时间资源。需要说明的是，位于不同时间位置的第一时间资源对应的波束方向可以相同，也可以不相同，不作具体限定。这样实现的好处在于，当系统开始支持第一类型终端设备业务传输时，不会因为第一类型终端设备的引入，影响系统中可能已经部署了的第二类型终端设备的业务传输，特别是当对应第二类型终端设备的公共信息传输与SSB传输在相同的时隙或者相同的无线帧内时，通过这种实现方式，可以避免对第二类型终端设备初始接入的影响。这里例如第一类型终端设备为NR REDCCAP终端设备，第二类型终端设备为NR已经部署的eMBB终端设备(例如NR R15/R16版本的终端设备)。
当不包括SSB传输的时间资源的无线帧内，不包括第二CORESET0的时间资源的时隙个数不足以支持所有波束方向对应的第一时间资源映射时，未映射完的第一时间资源继续在包括SSB传输的时间资源的无线帧内且不包括第二CORESET0的时间资源的时隙内映射。
在一个具体的实施方式中，对应同一个SSB的第一时间资源分布在一个无线帧内的连续两个时隙内。或者说，与一个SSB具有相同准共址(quasi colocation，QCL)关系的多个第一时间资源分布在一个无线帧内连续的时隙内。通过这种实现方式，可以保证在多个第一时间资源内传输的调度公共信息传输的控制信息之间的联合信道估计性能，便于终端设备实现合并检测性能。例如，如果对应同一个SSB索引的第一时间资源分布在连续两个时隙内，则优选地，对应同一个SSB索引的第一时间资源所在的时隙在相同的无线帧内，分布在连续的两个时隙内，便于终端设备在时间上连续检测对应相同SSB索引的CORESET0内包括的SIB1控制信息，保证信道估计性能。
在本申请中，不同波束方向对应的第一时间资源可以理解为：CORESET0关联的SSB索引不同，则对应不同的波束方向。即不同的波束方向可以通过SSB索引来区分，SSB索引不同，则与SSB关联的CORESET0对应的波束方向就认为是不同的。即使实际中，网络设备通过不同的SSB索引发送的相同波束方向的数据，在本申请中，也可以认为是不同波束方向。
在一个具体的实施方式中，第一时间资源是根据来自网络设备的第二配置信息确定的， 所述第二配置信息用于配置所述第二时间资源。下面结合一个具体的实例对此进行说明：
第一时间资源可以通过下述公式确定：
Figure PCTCN2020073794-appb-000003
其中，第二配置信息可以是MIB消息，各参数确定方式如下：
参数O和参数M可以根据MIB中包括的pdcch-ConfigSIB1指示直接确定。
L为SSB所在频段所能支持传输SSB的最大个数。在NR系统中，SSB将以一个半帧5 ms为单位，进行周期发送，包含SSB的半帧周期可为{5 ms,10 ms,20 ms,40 ms,80 ms,160ms}。一个半帧中SSB可以重复多次发送，最大的重复次数为L次。L的值由NR载波所在的频段决定。
Offset’代表时间偏移量，为预配置的值，或者通过第二配置信息指示。
i为第一CORESET0的时间资源所对应的SSB的index。
M’取值可以与M相同。
u对应不同的子载波间隔或者不同的参数集(numerology)，u的取值可以参考表2
表2：
μ 子载波间隔Δf＝2 μ·15[kHz]
0 15
1 30
2 60
3 120
4 240
通过上述计算得到的slot所在的无线帧索引可以通过slot索引对应的奇偶来确定，或者通过上述计算得到的slot优先在不包含NR SSB传输的无线帧内。
在一个具体的实施方式中，第一时间资源所在的时间资源(例如时隙)还可以通过下述公式确定：
Figure PCTCN2020073794-appb-000004
第一类型终端设备根据MIB中包括的pdcch-ConfigSIB1，确定上述公式中的O、M参数，再根据预定义的时间偏移量，结合上述公式计算得到的n0，确定第一时间资源所在的slot，这里的时间偏移量可以理解为对应相同的SSB索引，第一时间资源与第二时间资源之间的时间偏移量，例如如果pdcch-ConfigSIB1指示的O为0，则预定义的时间偏移量可以为5；又例如，无论pdcch-ConfigSIB1指示的O具体值是多少，时间偏移量都可以为5。或者，第一类型终端设备根据控制信息确定上述公式中的O、M参数取值，结合预定义的
Figure PCTCN2020073794-appb-000005
值，直接确定第一时间资源所在的slot，本申请实施例对该控制信息具体传输方式、以及承载的传输信道不作具体限定。同样地，通过这种方式计算得到的slot所在的无线帧索引可以通过slot索引对应的奇偶来确定，或者通过上述计算得到的slot优先在不包含NR SSB传输的无线帧内。
需要说明的是，在本申请提供的技术方案中，第一配置信息和第二配置信息可以是相 同的信息，第一配置信息和第二配置信息也可以是不同的信息，但承载在相同的下行数据传输信道中，例如下行数据传输信道可以包括但不限于广播信道、下行控制信息、下行共享信道，以下对此不再重复赘述。
需要说明的是，在本申请实施例中，第一时间资源与包括SSB传输的时间资源可以是时分复用(time domain multiplexing，TDM)的，即第一时间资源与包括SSB传输的时间资源在时间上是没有重叠的。例如包括SSB传输的时间资源与第一时间资源对应的时隙不同，或者对应的OFDM符号不同。
(二)第二种CORESET0的时间资源的设计方式
确定第一类型终端设备对应的第一控制资源集合0CORESET0的时间资源，第一时间资源包括于第二时间资源内。
在一个优选的实施方式中，该实施方式可以与上述描述中通过第一种或第二种频率的设计方式确定的第一初始BWP的频率资源联合使用。
需要说明的是，在本申请实施例中，第一时间资源与包括SSB传输的时间资源可以是TDM的，即第一时间资源与包括SSB传输的时间资源在时间上是没有重叠的。例如包括SSB传输的时间资源与第一时间资源对应的时隙不同，或者对应的OFDM符号不同。
(三)第三种CORESET0的时间资源的设计方式
确定第一类型终端设备对应的第一控制资源集合0CORESET0的时间资源，第一时间资源包括于同步信号块SSB的时间资源内。
需要说明的是，第一类型终端设备对应的SSB与第二类型终端设备对应的SSB可以相同，也可以不相同，本申请对此不作具体限定。
需要说明的是，这三种时间资源的设计方式的任意一种设计方式都可以与上述的三种频率资源的设计方式中的任意一种设计方式结合应用。比如，第一种频率资源的设计方式可以与第一种CORESET0的时间资源的设计方式结合应用，具体可以参照图3所示的示意图进行理解。第一种频率资源的设计方式可以与第二种CORESET0的时间资源的设计方式结合应用，具体可以参照图11所示的示意图进行理解。第一种频率资源的设计方式可以与第三种CORESET0的时间资源的设计方式结合应用，具体可以参照图12所示的示意图进行理解。第二种频率资源的设计方式可以与第一种CORESET0的时间资源的设计方式结合应用，具体可以参照图13所示的示意图进行理解。第二种频率资源的设计方式可以与第二种CORESET0的时间资源的设计方式结合应用，具体可以参照图9所示的示意图进行理解。第二种频率资源的设计方式可以与第三种CORESET0的时间资源的设计方式结合应用，具体可以参照图14所示的示意图进行理解。第三种频率资源的设计方式可以与第一种CORESET0的时间资源的设计方式结合应用，具体可以参照图15所示的示意图进行理解。第三种频率资源的设计方式可以与第二种CORESET0的时间资源的设计方式结合应用，具体可以参照图16所示的示意图进行理解。第三种频率资源的设计方式可以与第三种CORESET0的时间资源的设计方式结合应用，具体可以参照图10所示的示意图进行理解。可选地，网络设备通过自身的业务需求，可以灵活配置上述组合方式，比如网络设备可以配置X种配置，X种配置中至少包括一种上述组合方式。具体的，例如网络设备只配置1种配置，则这种配置可以为上 述组合中的一种，或者网络设备配置2种配置，这2种配置为上述组合中的至少两种。具体终端设备通过哪种配置确定第一初始BWP的频率资源和时间资源(CORESET0时间资源)，可以通过其他方式实现，本申请不作具体限定。
以上从如何确定初始BWP的频率资源以及如何确定CORESET0的时间资源对确定初始BWP的方法进行了介绍，需要说明的是，第一时间资源可以是周期出现的，下面将结合具体的实例对第一时间资源的周期设计方法进行说明。
(一)第一种第一时间资源的周期设计方式
由于第二时间资源可以是周期出现的，第一时间资源的周期可以与第二时间资源的周期相同，或者第一时间资源与第二时间资源的周期不同。比如，在一个具体的实施方式中，第一时间资源的周期可以为第二时间资源的周期的整数倍或者分数倍。第一时间资源与第二时间资源的周期不同，可以便于网络设备根据不同类型终端设备的能力，适配性地设计合适的时间资源用来承载公共信息的传输，在保证公共信息传输的性能特别是覆盖性能的同时，保证了资源使用的效率，避免网络设备侧不必要的资源开销。需要说明的是，本申请提供的第一种第一时间资源的周期设计方式可以单独应用，也可以和上述介绍的三种初始BWP的频率资源的设计方式以及三种CORESET0的时间资源的设计方式结合使用，具体的，当第一种时间资源的周期设计方式与任意一种CORESET0的时间资源的设计方式结合使用时，第一种时间资源的每一个周期的设计方式与CORESET0的时间资源的设计方式相同。
在一个具体的实施方式中，第一种第一时间资源的周期设计方式可以和第二种CORESET0的时间资源的设计方式结合应用，当和第二种CORESET0的时间资源的设计方式结合应用时，第一时间资源包括于第二时间资源内，可以包括以下至少一种理解：
(1)第一时间资源的周期与第二时间资源的周期相同，在第二CORESET0出现的第二时间资源内包括第一CORESET0的时间资源，例如在一个周期内，第二CORESET0的时间资源对应一个时隙中的第M1个OFDM符号～第M2个OFDM(包括第M1个和第M2个OFDM符号)包括的时间资源范围，则第一CORESET0的时间资源可以对应该时隙中的第M3～M4个OFDM符号(包括第M3和第M4个OFDM符号)，其中M3不小于M1，M4不大于M2。
(2)第一时间资源的周期与第二时间资源的周期不同，且第一时间资源的周期为第二时间资源周期的整数倍，并且在第一时间资源与第二时间资源重合的时间资源上，第一时间资源包括于第二时间资源内。
此外，可选地，第一时间资源还可以满足：第一时间资源的周期与第二时间资源的周期不同，且第一时间资源的周期为第二时间资源周期的分数倍，并且在第一时间资源与第二时间资源重合的时间资源上，第一时间资源包括于第二时间资源内。例如第二时间资源的周期为10ms，而第一时间资源的周期为5ms。在本申请实施例中，由于在重合的资源上，第一时间资源也是包括与第二时间资源内的，因此这种实施方式也可以理解为第一时间资源包括于第二时间资源内。
通过上述的实施方式，由于第一时间资源可以包括于第二时间资源内(如(1)和(2))，或者说，部分第一时间资源可以包括于第二时间资源内(如(3))，因此网络设备可以在第二时间资源范围内传输第一类型终端设备对应的公共信息，另一方面，网络设备在第二 时间资源内还会传输第二类型终端设备对应的公共信息，因此，网络设备在为不同类型终端设备发送公共信息时，网络设备可以增加关断符号的概率(例如被关断的符号可以是承载第一类型终端设备和第二类型终端设备对应的公共信息传输的符号)，进而减少网络设备传输数据所需的功耗。
(二)第二种第一时间资源的周期设计方式
由于SSB的时间资源是周期出现的，第一时间资源可以与第一类型终端设备对应的SSB的时间资源的周期相同，或者第一时间资源与第一类型终端设备对应的SSB的时间资源的周期不相同。在一个具体的实施方式中，第一时间资源的周期可以为SSB的时间资源的周期的整数倍或者分数倍。第一时间资源与SSB传输周期不同，可以便于网络设备根据不同数据的覆盖性能，适配性地设计合适的时间资源用来承载公共信息的传输，保证了资源使用的效率，避免网络设备侧不必要的资源开销。例如SSB传输，终端设备可以通过能量累加的方式，保证SSB传输性能，而对于包括公共信息传输的第一时间资源，可以通过设置与SSB不同的传输周期，来保证公共信息的传输性能。
需要说明的是，本申请提供的第二种第一时间资源的周期设计方式可以单独应用，也可以和上述介绍的三种初始BWP的频率资源的设计方式以及三种CORESET0的时间资源的设计方式结合使用，具体的，当第二种时间资源的周期设计方式与任意一种CORESET0的时间资源的设计方式结合使用时，第二种时间资源的每一个周期的设计方式与CORESET0的时间资源的设计方式相同。
在一个具体的实施方式中，当和第三种CORESET0的时间资源的设计方式结合应用时，第一时间资源包括于SSB的时间资源内，可以包括以下至少一种理解：
(1)第一时间资源的周期与SSB的时间资源的周期相同，在SSB出现的时间资源内包括第一CORESET0的时间资源，例如在一个周期内，SSB的时间资源对应一个时隙中的第M1个OFDM符号～第M2个OFDM(包括第M1个和第M2个OFDM符号)包括的时间资源范围，则第一CORESET0的时间资源可以对应该时隙中的第M3～M4个OFDM符号(包括第M3和第M4个OFDM符号)，其中M3不小于M1，M4不大于M2。
(2)第一时间资源的周期与SSB的时间资源的周期不同，且第一时间资源的周期为SSB的时间资源周期的整数倍，并且在第一时间资源与SSB的时间资源重合的时间资源上，第一时间资源包括于SSB的时间资源内。
(3)此外，可选地，第一时间资源还可以满足：第一时间资源的周期与SSB传输周期不同，且第一时间资源的周期为SSB传输周期的分数倍，并且在第一时间资源与第二时间资源重合的时间资源上，第一时间资源包括于SSB时间资源内。例如SSB的传输周期为10ms，而第一时间资源的周期为5ms。在本申请实施例中，由于在重合的资源上，第一时间资源也是包括与SSB时间资源内的，因此这种实施方式也可以理解为第一时间资源包括于SSB时间资源内。
通过(3)的方式，由于第一时间资源包括于的SSB时间资源内，或者部分第一时间资源包括于SSB时间资源内，因此可以增加网络设备关掉符号的概率，降低网络设备传输公共信息和SSB时所需的功耗。
需要说明的是，对于NR载波频率大于6GHz的第一时间资源也可以具有上述特征。
需要说明的是，在本申请实施例中，第一时间资源的周期或者包括公共信息传输的时间资源的周期或者第一CORESET0时间资源的周期可以是终端设备默认的周期，例如20ms，也可以是网络设备发送公共信息的周期或者实际发送公共信息的周期，例如网络设备发送公共信息的周期可以为5ms，10ms，20ms，40ms，……，而网络设备实际发送公共信息的周期可以是网络设备发送公共信息的周期中的任意一个取值。对于第二时间资源的周期也有相同说明，不作赘述，此外，SSB传输周期也可以是终端设备默认的周期，或者是网络设备发送SSB的周期或者实际发送SSB的周期，例如网络设备发送SSB的周期可以为5ms，10ms，20ms，40ms，……，而网络设备实际发送SSB的周期可以是网络设备发送公共信息的周期中的任意一个取值。
以上分别从频率资源的设计方式、CORESET0的时间资源的设计方式以及时间资源的周期设计方式三个方面对本申请提供的确定初始BWP的方法进行了介绍，本申请提供的设计方式设计简单，继承现有的第二初始BWP的设计初衷，降低标准设计复杂度。
可以理解的是，上述第一类型终端设备为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的模块及算法步骤，本申请能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请的范围。
从硬件结构上来描述，图3至图16中的第一类型终端设备可以由一个实体设备实现，也可以由多个实体设备共同实现，还可以是一个实体设备内的一个逻辑功能模块，本申请实施例对此不作具体限定。
