附图说明
图1是本发明实施例的一种接入资源的确定方法的流程示意图；
图2是本发明实施例的一种接入资源的确定装置的结构示意图。
具体实施方式
如背景技术所言，现有技术缺少获取和配置窄带CORESET0和/或窄带初始激活下行BWP的技术解决方案。
具体而言，在NR版本15(Release 15)***中，同步信号、广播信道信号是以同步信号块(Synchronization Signal and Physical Broadcast Channel Block)的方式发送的，并且，5G***还引入了波束扫描(beam sweeping，亦称扫波束)等功能。每个同步信号块可以看作是波束扫描过程中的一个波束对应的资源。其中，同步信号块包含主同步信号(Primary Synchronization Signal，简称PSS)、辅同步信号(Secondary Synchronization Signal，简称SSS)和物理广播信道(Physical Broadcast Channel，简称PBCH)信号。多个同步信号块可以组成一个同步信号突发(synchronization signal burst)。同步信号突发可以看作是包含多个波束的一块相对集中的资源。多个同步信号突发组成一个同步信号突发集合(synchronization signal burst set)。同步信号块在不同波束上重复发送，完成波束扫描过程。通过波束扫描的训练，用户设备可以确定在哪个波束上收到的信号最强。
例如，可以假设L个同步信号块在5毫秒(millisecond，简称ms)窗口内的时域位置是固定的。也即，同步信号块在所述5ms窗口内的发射时刻是固定的，索引也是固定的。其中，L个同步信号块的索引在时域位置上是连续排列的，从0到(L-1)，L是正整数。
进一步，Release 15 NR中的剩余最小***信息(Remaining Minimum System Information，简称RMSI，也可以称为SIB1，即System Information Block 1)相当于LTE中的SIB1，其包括除了MIB外的主要的***信息。RMSI也可以称为SIB1。RMSI是在PDSCH里承载的，而PDSCH是通过物理下行控制信道(Physical Downlink Control Channel，简称PDCCH)调度的。承载RMSI的PDSCH一般被称为RMSI PDSCH，调度RMSI PDSCH的PDCCH一般被称为RMSI PDCCH。
一般地，搜索空间集合(search space set)包含PDCCH的监听时机、搜索空间类型等性质。搜索空间集合一般会绑定控制资源集合(Control Resource Set，简称CORESET)，并且，CORESET包含PDCCH的频域资源和持续时间等性质。
RMSI PDCCH(或称SIB1 PDCCH，或称Type0-PDCCH)所在的搜索空间(search space set)一般被称为Type0-PDCCH search space set或Type0-PDCCH common search space set。一般地，由MIB配置的，或者在切换等情形下由无线资源控制(Radio Resource Control，简称RRC)配置的。一般地，Type0-PDCCH search space set对应的识别号(Identity，简称ID)为0，因此也可以被称为search space 0(或search space set 0)，所绑定的CORESET被称为CORESET 0。除了RMSI PDCCH的search space set，其他的公共搜索空间或公共搜索空间集合，如其它***信息(Other System Information，简称OSI)PDCCH的search space set(Type0A-PDCCH search space set)、随机接入响应(Random Access Response，简称RAR)PDCCH的search space set(Type1-PDCCH search space set)、寻呼(paging)PDCCH的search space set(Type2-PDCCH search space set)等，可以默认地与search space set 0相同。一般地，上述公共搜索空间或公共搜索空间集合都可以被重新配置。
RMSI PDCCH监听时机与同步信号块有关联关系。UE根据RMSI  PDCCH监听时机表格获得此关联关系。在初始接入过程中，UE搜索到某个同步信号块，UE根据PBCH指示的表格的行索引，确定该同步信号块关联的RMSI PDCCH的时域位置(起始符号索引或第一个符号索引)，就能够检测出RMSI PDCCH，并根据RMSI PDCCH调度来接收和解码RMSI PDSCH。
在Release 15 NR中，UE解码RMSI PDCCH，获取时域资源分配的多个比特，根据这些比特查找预定义的表格来获得RMSI PDSCH的起始符号索引(或编号)和符号长度(或持续时间(duration))。
在Release 15 NR中，UE在初始接入阶段，UE假设RMSI PDSCH不对同步信号块进行速率匹配。RMSI可以指示同步信号块的是否发送的信息，当UE获得RMSI后，可以对RMSI指示的同步信号块进行速率匹配。
UE需要通过同步信号块获得定时信息。定时信息也可以称为帧定时(frame timing)信息，或半帧定时(half-frame timing)信息，一般用于指示所检测到的同步信号对应的帧或半帧的定时。UE获得帧定时信息后，再通过SFN(System Frame Number，简称***帧号)，来获得同步信号块对应小区的完整定时信息。UE获得半帧定时信息后，再通过半帧指示(前半帧还是后半帧)和SFN，来获得同步信号块对应小区的完整定时信息。
一般来说，UE通过获取同步信号块索引来获得10毫秒内定时信息。在授权频谱中，同步信号块索引跟同步信号块的L个候选位置有关，L为正整数。当L＝4，同步信号块索引的低2个比特(2LSBs)在PBCH-DMRS(PBCH解调参考信号)来承载；当L>4，同步信号块索引的低3个比特(3LSBs)在PBCH-DMRS来承载；当L＝64，同步信号块索引的高3个比特(3MSBs)在PBCH负荷(payload)或MIB来承载。
在Release 15 NR中，对于给定的UE，其对应的寻呼时机由多个寻呼PDCCH监听时机组成。在一个寻呼时机内，寻呼PDCCH可以 跟同步信号块一样通过扫波束的方式发送。在一个寻呼时机内，寻呼PDCCH监听时机和同步信号块一一对应，即在一个寻呼时机内，第K个寻呼PDCCH监听时机对应第K个同步信号块。
在LTE版本13(Release13)的增强型机器类型通信(enhanced Machine-Type Communication，简称eMTC)中，eMTC UE是窄带(narrowband)UE。eMTC UE的带宽约为1MHz，可以覆盖6个PRBs。因此，eMTC UE在初始接入时，可以检测出LTE的主同步信号(Primary Synchronization Signal，简称PSS)/辅同步信号(Secondary Synchronization Signal，简称SSS)/物理广播信道(Physical Broadcast CHannel，简称PBCH)。由于PBCH内携带的MIB(Master Information Block，简称主信息块)，因此eMTC UE可以解码出LTE的MIB。并且，LTE的MIB有10个保留的比特(Spare bits)，这些保留的比特的一部分可以用来承载调度eMTC的SIB1(SIB1-BR，不同于LTE SIB1)的信息。默认地，携带eMTC SIB1的PDSCH的频域资源也在6个物理资源块(Physical Resource Block，简称PRB)内，因此eMTC UE也可以接收携带eMTC SIB1的PDSCH。这样的话，eMTC UE解码出LTE的MIB后，获取其中的eMTC SIB1信息，进而接入网络。
在Release-15NR中，一般地，UE是支持100MHz带宽的UE。UE在初始接入时，盲检同步信号块中的PSS/SSS/PBCH，获得PBCH内携带的MIB和时间索引信息。UE通过MIB中的信息获得调度SIB1(或RMSI)的PDCCH所属的CORESET(可以称为CORESET0)和search space set(可以称为search space set 0)的配置，进而，UE可以监听调度承载SIB1的PDSCH的Type0-PDCCH，并解码出SIB1。由于PBCH内通过表格来设置CORESET0的带宽，所以CORESET0的最大带宽在协议中被隐式地定义了。进一步来说，协议规定承载SIB1的PDSCH的频域资源在CORESET0的带宽(PRB)内，因此承载SIB1的PDSCH的最大带宽在协议中也被隐式地定义了。
当前，对于窄带UE，可能需要定义窄带CORESET0和/或窄带初始激活下行BWP(即承载窄带SIB1的PDSCH的频率范围)，和/或窄带SIB1(或窄带RMSI),因为CORESET0或初始激活下行BWP或SIB1(RMSI)不一定适合窄带UE接收。一般来说，在初始接入过程中，窄带CORESET0的带宽默认为窄带初始激活下行BWP，而在获得额外信息后，窄带初始激活下行BWP的带宽可以被扩展。对于窄带UE如何获取和配置窄带CORESET0(或Type0-PDCCH common search space set的CORESET)和窄带初始激活下行BWP，现有技术还未给出解决方案，如何获取和配置窄带初始激活下行BWP也未给出解决方案。
本发明实施例提供一种接入资源的确定方法，包括：确定窄带CORESET0和/或窄带初始激活下行BWP的频域位置，和/或，确定窄带SIB1。一般来说，所述窄带CORESET0的带宽小于或等于CORESET0的带宽，所述窄带PBCH的带宽小于或等于PBCH的带宽。本发明实施例通过确定窄带PBCH、窄带CORESET0、窄带初始激活下行BWP的频域位置，可以确定窄带UE的接入资源，进而获取和配置窄带CORESET0和承载SIB1的PDSCH，以及窄带初始激活下行BWP的最大带宽。
为使本发明的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。

图1是一种接入资源的确定方法的流程示意图。所述确定方法可以用于终端(User Equipment，简称UE)侧，可以仅包括步骤S101，也可以包括步骤S101和步骤S102：
步骤S101：确定窄带CORESET0和/或窄带初始激活下行BWP的频域位置，和/或，确定窄带SIB1。
一般来说，所述窄带CORESET0的带宽小于或等于CORESET0的带宽，所述窄带PBCH的带宽小于或等于PBCH的带宽。
更具体而言，在步骤S101中，在一个实施例中，所述窄带UE可以重用Release 15的同步信号块。所述窄带CORESET0与窄带UE的接入资源可以具有预设关联关系。在具体实施中，所述预设关联关系可以包括：窄带CORESET0和/或窄带初始激活下行BWP的带宽是预设值。其中该预设值与band关联。在具体实施中，所述预设关联关系可以包括：所述窄带CORESET0的PDSCH的最低PRB等于CORESET0的最低PRB，和/或，所述窄带初始激活下行BWP的最低PRB等于CORESET0的最低PRB。其中该预设值与band关联。基于所述预设关联关系，窄带UE可以确定窄带CORESET0，和/或，窄带UE能够使用的窄带初始激活下行BWP的频域位置。
进一步，本领域技术人员理解，通常情况下，窄带UE的窄带初始激活下行BWP的频域资源默认等于窄带CORESET0的频域资源，因而，确定所述窄带初始激活下行BWP后，可以一并得知窄带CORESET0的频域资源。
在一个实施例中，所述窄带CORESET0的带宽可以为预设值，和/或，所述窄带初始激活下行BWP的带宽可以为预设值。所述预设值与窄带UE接入的频带(band)有关。
在另一个实施例中，所述窄带UE可以重用Release 15的同步信号块。所述窄带CORESET0与窄带UE的接入资源可以具有预设关联关系。在具体实施中，所述预设关联关系可以包括：所述窄带CORESET0的最低PRB与CORESET0或同步信号块的最低PRB之间的偏移量为预设值。和/或，所述窄带初始激活下行BWP的最低PRB与CORESET0的最低PRB之间的偏移量为预设值。基于所述预设关联关系和所述偏移量，窄带UE可以确定窄带CORESET0，和/ 或，窄带初始激活下行BWP的频域位置，和/或承载SIB1的PDSCH的频域资源。本发明实施例中，同步信号块的最低PRB可以是Common RB中与同步信号块的最低PRB重叠的最低PRB。需要注意的是，有时候，同步信号块的真正最低的子载波可能与此PRB的最低的子载波有子载波级别的偏移。本发明中与任何频域资源(如CORESET0，窄带CORESET0，初始激活下行BWP等)与同步信号块的频域偏移量都可以是指该频域资源的最低PRB与Common RB中与同步信号块的最低PRB重叠的最低PRB之间的偏移量。
例如，所述偏移量的带宽大于或等于所述窄带CORESET0的带宽，和/或，所述偏移量的带宽大于或等于所述窄带初始激活下行BWP的带宽。
又例如，所述偏移量包含的PRB数量大于或等于所述窄带CORESET0包含的PRB数量，和/或，所述偏移量包含的PRB数量大于或等于所述窄带初始激活下行BWP包含的PRB数量。
进一步，所述窄带UE可以根据所述窄带CORESET0与CORESET0或同步信号块之间的偏移量，确定所述窄带CORESET0的最低PRB。或者，可以根据所述窄带初始激活下行BWP与同步信号块之间的偏移量，确定所述窄带初始激活下行BWP的最低PRB。所述窄带UE可以根据所述窄带CORESET0的最低PRB与CORESET0或同步信号块的最低PRB之间的偏移量，确定所述窄带CORESET0的最低PRB。或者，可以根据所述窄带初始激活下行BWP与CORESET0或同步信号块的最低PRB之间的偏移量，确定所述窄带初始激活下行BWP的最低PRB。
进一步，如果窄带UE位于频率范围1(Frequency Range 1，简称FR1)，那么基站可以将所述偏移量置于PBCH中，由所述PBCH内的同步信号块索引携带。因为对于FR1，PBCH内的同步信号块索引是保留比特，并不用来指示同步信号块索引。
作为一个变化例，如果窄带UE位于频率范围2(Frequency Range  2，简称FR2)，那么基站可以将所述偏移量置于PBCH中，在Type0-PDCCH监听时机指示中携带。在具体实施例中，当所述同步信号块和CORESET复用模式为2或3时，所述Type0-PDCCH监听时机指示可以在含义上等价于Type0-PDCCH监听时机表格，因为此时Type0-PDCCH监听时机指示有3比特是保留的，可以用于指示所述偏移量。
监听作为另一个变化例，当所述同步信号块和CORESET复用模式为2时，所述偏移量在Type0-PDCCH监听时机中携带。
作为另一个变化例，当所述同步信号块和CORESET复用模式为3时，所述偏移量在Type0-PDCCH监听时机指示中携带。
在另一个实施例中，所述窄带UE可以重用Release 15的PSS及SSS，并采用不同于现有技术中的PBCH的窄带PBCH，所述窄带PBCH指的是供窄带UE使用的PBCH，一般来说其带宽小于或等于PBCH带宽。在此条件下，窄带UE可以先接收PBCH，所述PBCH中可以指示窄带UE接收所述窄带PBCH。当PBCH中指示有窄带PBCH时，窄带UE可以接收窄带PBCH，并确定窄带初始激活下行BWP的频域位置。
当窄带UE可以重用Release 15的PSS及SSS，并采用窄带PBCH时，可以设置所述窄带PBCH带宽为预设值。所述预设值与窄带UE接入的频带(band)有关。当窄带UE可以重用Release 15的PSS及SSS，并采用窄带PBCH时，可以设置所述窄带PBCH的最低PRB与同步信号块的最低PRB之间的偏移量为预设值。所述预设值与窄带UE接入的频带(band)有关。在具体实施时，所述偏移量的带宽可以大于或等于所述窄带PBCH的带宽。或者，所述偏移量包含的PRB数量可以大于或等于所述窄带PBCH包含的PRB数量。
在另一个实施例中，所述窄带UE可以采用全新的窄带PSS、窄带SSS和窄带PBCH。在具体实施中，所述窄带UE可以盲检窄带PSS、窄带SSS，获得窄带PBCH的时频位置。之后，窄带UE接收所述窄 带PBCH，以得到窄带PBCH信息。一般来说，所述窄带PSS的带宽小于或等于PSS的带宽，所述窄带SSS的带宽小于或等于SSS的带宽。所述窄带PBCH信息可以包含：所述窄带CORESET0和/或窄带初始激活下行BWP的最低PRB与同步信号块的最低PRB之间的偏移量。进一步，所述窄带UE可以获取窄带CORESET0和/或窄带初始激活下行BWP的频域位置，以及窄带初始激活下行BWP的频域资源。
之后，可以执行步骤S102，即在所述频域位置接收CORESET0和/或窄带初始激活下行BWP，和/或，接收窄带SIB1。
当窄带UE支持的带宽小于CORESET0或承载SIB1的PDSCH的最大带宽时，窄带UE可以按照如下具体实施例所述方式，获取窄带CORESET0和窄带初始激活下行BWP。
实施例一：重用Release 15的同步信号块。
对于窄带CORESET0和/或窄带初始激活下行BWP的带宽，默认地，窄带UE假设窄带CORESET0和/或窄带初始激活下行BWP的带宽与需要接入的带宽具有预设的关联关系。对于窄带CORESET0和/或窄带初始激活下行BWP的频域位置，可以采用如下方案：
方案1：默认地，窄带CORESET0和/或窄带初始激活下行BWP的最低的PRB为CORESET0的最低的PRB。该方案适合于CORESET0的时频资源较多和承载SIB1的PDSCH的时频资源较多的情形，因为此时CORESET0的部分资源可能被窄带CORESET0的Type0-PDCCH占据，承载SIB1的PDSCH的部分资源可能被窄带初始激活下行BWP占据。
方案2：默认地，窄带CORESET0和/或窄带初始激活下行BWP的最低的PRB和CORESET0或同步信号块的最低的PRB之间的偏移量为预设值。所述预设值对应的带宽大于等于窄带CORESET0和/或窄带初始激活下行BWP的带宽。也就是说，所述预设值带宽对应 某个子载波间隔下的PRB数大于等于窄带CORESET0和/或窄带初始激活下行BWP的带宽对应某个子载波间隔下的PRB数。该方案适合于CORESET0的时频资源较少和承载SIB1的PDSCH的时频资源较少的情形。
方案3：窄带UE通过获取同步信号块或CORESET0和窄带CORESET0的偏移量，获得窄带CORESET0的位置。更具体地说，窄带UE通过获取同步信号块或CORESET0的最低PRB与窄带CORESET0的最低PRB之间的偏移量，获得窄带CORESET0的最低PRB的位置。由于重用Release 15的同步信号块，因此所述偏移量可以通过同步信号块内的保留比特或者保留码本点(codepoints)来传递。
对于频率范围1，窄带UE可以通过获取PBCH内的同步信号块索引(即同步信号块时间索引的高3比特，3MSB)来获取所述偏移量。对于频率范围2，窄带UE可以通过获取PBCH内的Type0-PDCCH监听时机指示(4个比特，用表格定义)的保留比特或codepoints来获取所述偏移量。在一个例子中，当在FR2中同步信号块和CORESET复用模式为2时，Type0-PDCCH监听时机指示表示所述偏移量。在另一个例子中，当在FR2中同步信号块和CORESET复用模式为3时，Type0-PDCCH监听时机指示所述偏移量。
实施例二：重用Release 15的PSS/SSS，采用窄带PBCH。
默认地，窄带PBCH的带宽是预设值。其中该预设值与band关联。默认地，窄带PBCH的最低PRB与同步信号块的最低PRB的偏移量为预设值。所述偏移量对应的带宽大于等于窄带PBCH的带宽。也就是说，所述偏移量对应某个子载波间隔下的PRB数大于等于窄带PBCH的带宽对应某个子载波间隔下的PRB数。UE通过获取所述窄带PBCH指示，来获取窄带CORESET0和/或窄带初始激活下行BWP的带宽和频域位置。具体地说，窄带UE可以通过获取所述窄带PBCH指示的同步信号块的最低PRB与窄带CORESET0和/或窄 带初始激活下行BWP最低PRB之间的偏移量，获取窄带CORESET0和/或窄带初始激活下行BWP的频域位置。
实施例三：窄带UE是否完全重用Release 15的同步信号块由PBCH指示。
窄带UE接收到PBCH，并从PBCH信息(例如，MIB)得知，窄带UE是否完全重用Release 15的同步信号块。在具体实施中，当窄带UE支持的带宽大于或等于CORESET0或承载SIB1的PDSCH的最大带宽时，窄带UE可以通过接收CORESET0或承载SIB1的PDSCH，来获取窄带CORESET0和承载窄带SIB1的PDSCH。
实施例四：
所述窄带UE可以接收CORESET0中的Type0-PDCCH，获得承载SIB的PDSCH的调度信息。之后，所述窄带UE可以利用所述调度信息，接收承载SIB的PDSCH，获取SIB消息。所述SIB消息可以包含所述窄带CORESET0和/或所述窄带初始激活下行BWP。例如，所述SIB消息可以包含窄带SIB1消息和SIB1消息。所述窄带SIB1消息可以包含窄带CORESET0和/或所述窄带初始激活下行BWP。该技术方案的优势在于，窄带UE既接收了SIB1，又接收了窄带SIB1，而SIB1中有些信息对于窄带UE是有用的，比如小区级别的信息，窄带UE可以获取到这些对其有用的SIB消息。
实施例五：
窄带UE可以接收CORESET0中的Type0B-PDCCH，其中Type0B-PDCCH为调度承载窄带SIB1的PDSCH的PDCCH。之后，所述窄带UE可以从Type0B-PDCCH中，获得承载窄带SIB1的PDSCH的调度信息。所述窄带UE可以接收承载窄带SIB1的PDSCH，获取窄带SIB1。所述窄带SIB1的带宽小于或等于所述SIB1的带宽。窄带UE还可以接收CORESET0中的Type0A-PDCCH，其中Type0A-PDCCH为调度承载OSI的PDSCH的PDCCH。之后，所述 窄带UE可以从Type0A-PDCCH中，获得承载OSI的PDSCH的调度信息。所述窄带UE可以接收承载OSI的PDSCH，获取OSI。OSI可以包含所述窄带SIB1。该技术方案的优势在于，窄带UE可以选择性地接收SIB1或窄带SIB1，节省终端能耗。在实际应用中，根据基站指示或者不同场景，窄带UE可以选择当前需要接收的SIB1或窄带SIB1。具体地说，UE可以获取寻呼中的消息，如果所述消息指示***更新(System information update)，那么UE可以接收SIB1，如果所述消息指示窄带***更新，那么UE可以接收窄带SIB1。
实施例六：
在具体实施中，可以通过PBCH内的比特指示Type0-PDCCH是否调度承载窄带SIB1的PDSCH，例如，利用PBCH信息中的一个比特指示是否存在窄带PBCH。
具体实施中，所述PBCH可以指示同步信号块与CORESET0的偏移量，由偏移量与阈值的比较结果确定是否存在窄带PBCH。如果所述偏移量小于或等于某个阈值，那么可以表示存在窄带PBCH，并按照实施例二中提供的方案确定窄带CORESET0，和/或，窄带初始激活下行BWP的频域位置。否则，如果所述偏移量大于所述阈值，那么可以按照实施例一确定窄带CORESET0，和/或，窄带初始激活下行BWP的频域位置。
本领域技术人员理解，当所述偏移量为零或正数时，同步信号块的最低PRB的在公共资源块(Common Resource Block)中的编号比CORESET0的最低PRB的在公共资源块中的编号高。这样做的好处是：如果所述偏移量小于或等于某个阈值，那么同步信号块与CORESET0的频域资源的底端差不多是对齐，因此，基站对承载SIB1(包含窄带SIB1)的PDSCH的频域资源分配可以从同步信号块的最高PRB的上方开始连续分配PRB；否则，同步信号块与CORESET0的频域资源的底端有一定的频域间隔，因此，基站对承载SIB1的PDSCH的频域资源分配可以从同步信号块的最高PRB的上方开始连 续分配PRB，而对窄带初始激活下行BWP的频域资源分配可以从CORESET0的最低PRB开始连续分配PRB，从而可以达到对资源的充分利用。
由上，本发明实施例提供的技术方案，为确定窄带UE的接入资源，进而获取和配置窄带CORESET0和承载SIB1的PDSCH，以及窄带初始激活下行BWP的频域资源的最大带宽提供了可行方案。
图2是本发明实施例的一种接入资源的确定装置的结构示意图。所述接入资源的确定装置2(以下简称确定装置2)可以用于实施图1所示方法技术方案，由UE执行。
具体而言，所述确定装置2可以包括：确定模块21，适于确定窄带CORESET0和/或窄带初始激活下行BWP的频域位置，和/或，确定窄带SIB1。
在具体实施中，所述窄带CORESET0和/或窄带初始激活下行BWP的最低PRB可以等于CORESET0的最低PRB。
在具体实施中，所述窄带CORESET0和/或窄带初始激活下行BWP的带宽为预设值。
在具体实施中，所述窄带CORESET0的最低PRB等于CORESET0的最低PRB，和/或，所述窄带初始激活下行BWP的最低PRB等于CORESET0的最低PRB。
