Description

资源信息的确定方法及装置、存储介质、用户设备
本申请要求于2018年09月28日提交中国专利局、申请号为201811141263.9、发明名称为“资源信息的确定方法及装置、存储介质、用户设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信技术领域，尤其涉及一种资源信息的确定方法及装置、存储介质、用户设备。
背景技术
在现有的Release 15 NR技术中，初始激活下行(Initial Active Downlink)带宽部分(Band-width Part，BWP)的位置通常等于第一类PDCCH(Type0-PDCCH search space set)的控制资源集(Control-resource set，CORESET)的位置。因此，用户设备(又称为终端)根据管理信息库(Management Information Base，MIB)或者无线资源控制层(Radio Resource Control，RRC)指示的第一类PDCCH的CORESET的位置就能直接获得初始激活下行BWP的位置。其中，所述第一类PDCCH又称为剩余最小系统信息(Remaining minimum system information，RMSI)PDCCH。
然而，在NR非授权频谱里，在5GHz频谱以内，初始激活下行BWP的带宽接近20MHz，并且可以固定在WiFi信道内。而第一类PDCCH的CORESET可以有一定自由度，比如带宽小于20MHz。因此，初始激活下行BWP的位置可以不等于第一类PDCCH的 CORESET的位置。

具体实施方式
在现有技术中，初始激活下行BWP的位置通常等于第一类PDCCH(Type0-PDCCH search space set)的CORESET的位置，然而，在NR非授权频谱里，初始激活下行BWP的位置可以不等于第一类PDCCH的CORESET的位置，导致用户设备难以确定初始激活下行BWP的资源配置和第一类PDCCH的资源配置信息。
本文中，最小索引的PRB(Physical Resource Block)也可以称为第一个PRB，即同步信号块的最小索引的PRB可以称为同步信号块的第一个PRB，初始激活下行BWP的最小索引的PRB可以称为初始激活下行BWP的第一个PRB，第一类PDCCH的CORESET的最小索引的PRB可以称为第一类PDCCH的CORESET的第一个PRB。
本文中，初始激活下行BWP的PRB数量也可以称为初始激活下行BWP的连续PRB数量。
在本文中，同步信号块的最小索引的PRB可以是与相应的同步信号块重叠的common RB(公共资源块，common Resource Block)上的最小索引的PRB。
本文中的PRB也可以称为RB(资源块，Resource Block)。
本文中，位图资源单位又可以称为PRB组。一般情况下，位图中比特为1表示位图资源单位中的PRB为所述CORESET的PRB，位图中比特为0表示位图资源单位中的PRB不是所述CORESET的PRB。本文中，预先划分的信道可以为预先划分的频率范围，预先划 分的信道也可以为针对非授权频谱预先划分的频率范围，比如WiFi技术定义下的20MHz信道。
在本发明实施例中，根据所述同步信号块的最小索引的PRB的频域位置，确定初始激活下行BWP的位置，进而确定第一类PDCCH的CORESET的位置。采用本发明实施例的方案，可以使用户设备在NR非授权频谱里，能够获得初始激活下行BWP的资源配置和第一类PDCCH的资源配置信息。
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。
参照图1，图1是本发明实施例中第一种资源信息的确定方法的流程图。所述第一种资源信息的确定方法可以包括步骤S11至步骤S13：
步骤S11：确定同步信号块的最小索引的PRB的频域位置；
步骤S12：根据所述同步信号块的最小索引的PRB的频域位置，确定初始激活下行BWP的位置，其中，所述初始激活下行BWP的位置包括所述初始激活下行BWP的最小索引的PRB的频域位置以及所述初始激活下行BWP的PRB数量；
步骤S13：确定第一类PDCCH的CORESET的位置，其中，所述CORESET的位置包括所述CORESET的最小索引的PRB的频域位置以及所述CORESET的PRB数量，或者所述CORESET的基于位图的PRB位置。
在本发明实施例中，采用所述CORESET的最小索引的PRB的频域位置以及所述CORESET的PRB数量来确定所述CORESET的位置，所述CORESET的位置是连续的PRB，所述CORESET的PRB数量是连续的PRB数量。
在本发明实施例中，采用所述CORESET的基于位图的PRB位置确定所述CORESET的位置，所述CORESET的位置可以是非连续 的PRB。这种方法更具有灵活性。
在步骤S11的具体实施中，确定同步信号块的最小索引的物理资源块(Physical Resource Block，PRB)的频域位置。
在5G系统中同步信号、广播信道是以同步信号块的方式发送的，并且引入了扫波束的功能。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)在同步信号块(SS/PBCH block)中。每个同步信号块可以看作是扫波束(beam sweeping)过程中的一个波束(模拟域)的资源。多个同步信号块组成一个同步信号突发(SS-burst)。同步信号突发可以看作是包含了多个波束的相对集中的一块资源。多个同步信号突发组成一个同步信号突发集合(SS-burst-set)。同步信号块在不同波束上重复发送，是一个扫波束的过程，通过扫波束的训练，用户设备可以感知在哪个波束上收到的信号最强。
其中，L个同步信号块在一个5ms窗口内的时域位置是固定的。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。因此一个同步信号块在这个5ms窗口内的发射时刻是固定的，索引也是固定的。
在步骤S12的具体实施中，可以根据所述同步信号块的最小索引的PRB的频域位置，确定初始激活下行BWP的位置。
具体地，可以采用多种方式确定初始激活下行BWP的位置，例如根据基站提供的偏移量(Offset)确定所述初始激活下行BWP的频域位置，从基站获取初始激活下行BWP的PRB数量，具体的确定方式会在后续的具体实施例中进行说明。
在步骤S13的具体实施中，可以确定第一类PDCCH的CORESET的基于位图的PRB位置。
具体地，可以采用多种方式确定第一类PDCCH的CORESET的 位置，例如从基站获取，或者根据基站提供的偏移量(Offset)确定所述第一类PDCCH的CORESET的频域位置，从基站获取第一类PDCCH的CORESET的PRB数量，还可以通过位图，确定第一类PDCCH的CORESET的基于位图的PRB位置，具体的确定方式会在后续的具体实施例中进行说明。
其中，所述第一类PDCCH可以为RMSI PDCCH，在NR非授权频谱里，RMSI PDCCH的监测时机跟RMSI PDCCH的CORESET持续时间也有关系，这样可以确保同步信号块跟RMSI PDCCH的时域资源在一个突发内。
作为一个非限制性的具体应用，可以根据所述CORESET的最小索引的PRB的频域位置，获取所述CORESET并确定所述RMSI PDCCH，根据所述RMSI PDCCH以及所述初始激活下行BWP的最小索引的PRB的频域位置，接收所述RMSI PDCCH在所述初始激活下行BWP上调度的PDSCH。
在本发明实施例中，根据所述同步信号块的最小索引的PRB的频域位置，确定初始激活下行BWP的位置，进而确定第一类PDCCH的CORESET的位置。采用本发明实施例的方案，可以使用户设备在NR非授权频谱里，能够获得初始激活下行BWP的资源配置和第一类PDCCH的资源配置信息。
参照图2，图2是本发明实施例中第二种资源信息的确定方法的流程图。所述第二种资源信息的确定方法可以包括步骤S21至步骤S25，以下对各个步骤进行说明。
在步骤S21中，从基站获取所述同步信号块的最小索引的PRB和所述初始激活下行BWP的最小索引的PRB的频域位置之间的第一偏移量。
需要指出的是，所述同步信号块的最小索引的PRB的频域位置可以是通过检测获取的，具体可以参照图1示出的步骤S11的相关描 述，此处不再赘述。
在步骤S22中，根据所述第一偏移量以及所述同步信号块的最小索引的PRB的频域位置，确定所述初始激活下行BWP的最小索引的PRB的频域位置。
在步骤S23中，从基站获取初始激活下行BWP的PRB数量。
在本发明实施例的一种具体实施方式中，从基站获取的可以是初始激活下行BWP的PRB数量。
在本发明实施例的另一种具体实施方式中，从基站获取的可以是初始激活下行BWP的资源单位的数量，然后用户设备根据所述资源单位的数量确定所述PRB数量。
在步骤S24中，从基站获取所述第一类PDCCH的CORESET的位图资源单位的位图，其中，每个资源单位包括一个或多个PRB，位图资源单位和位图中的比特一一对应。
在具体实施中，所述位图资源单位的起始位置可以通过基站指示确定，或者可以是初始激活下行BWP的最小索引的PRB的频域位置。
在具体实施中，所述第一类PDCCH的CORESET的频域资源并不是连续的，所以具有较高自由度。
需要指出的是，所述比特可以对应于位图(bitmap)中的位(bit)的概念，如果所述位图中最小单位采用除比特之外的其他单位表示，则所述每个资源单位可以对应所述位图中的其他的最小单位。
在一个非限制性的例子中，所述每个资源单位可以包括6个PRB。

本发明实施例还提供了一种存储介质，其上存储有计算机指令，所述计算机指令运行时执行上述图1至图9示出的资源信息的确定方法的步骤。所述存储介质可以是计算机可读存储介质，例如可以包括非挥发性存储器(non-volatile)或者非瞬态(non-transitory)存储器，还可以包括光盘、机械硬盘、固态硬盘等。
本发明实施例还提供了一种用户设备，包括存储器和处理器，所述存储器上存储有能够在所述处理器上运行的计算机指令，所述处理器运行所述计算机指令时执行上述图1至图9示出的资源信息的确定方法的步骤。所述用户设备包括但不限于手机、计算机、平板电脑等用户设备。
可以理解的是，在LTE Release 12中，定义了发现参考信号(Discovery Reference Signal，DRS)，用于用户设备对SCell(Secondary Cell)的同步(时频跟踪)和测量，可以称为SCell的“发现”功能。采用DRS的好处是DRS是长周期信号，长周期信号对整个网络的干扰较小。DRS由PSS/SSS/CRS组成，其中CRS为小区指定参考信号(Cell-specific Reference Signal)。对于FDD系统，DRS持续时间(Duration)为1到5个连续子帧(subframe)；对于TDD系统，DRS持续时间为2到5个连续子帧。DRS的发射时机由发现测量时间配置(Discovery Measurement Timing Configuration，DMTC)定义，用户设备假设DRS在每个DMTC周期内出现一次。
在LTE的授权辅助接入(Licensed Assisted Access，LAA)中，DRS正好可以用于非授权频谱上的SCell的发现功能，因为其长周期特性，对减少对LAA系统和共享非授权频谱的异系统(如Wifi系统)的干扰。LAADRS的持续时间为一个非空子帧内的12个OFDM符号，以进一步减少对LAA系统和异系统的干扰。LAADRS同样包括PSS/SSS/CRS。
LAADRS的出现时机有两种情况：
情况一：用户设备可能假设LAADRS可能出现在DMTC中的任一子帧中，并且用户设备可能假设LAADRS出现在DMTC中包含一个PSS,一个SSS和CRS的第一个子帧上。也就是说，用户设备假设：在DMTC内基站进行发射前监听(Listen Before Talk，LBT)，如果监听到信道空闲，那么基站在一个非空子帧上发送一个DRS。
情况二：当LAADRS与PDSCH/PDCCH/EPDCCH一起传输时， LAADRS可能仅在子帧0和子帧5出现。也就是说，如果DMTC包含子帧0或5，并且用户设备在子帧0或5上需要检测PDCCH/EPDCCH或接收PDSCH，那么用户设备假设DRS只在子帧0或5上出现。
进一步地，5G中的剩余最小系统信息相当于LTE中的SIB1，其包括除了MIB外的主要的系统信息。RMSI是在PDSCH里承载的，而PDSCH是通过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，search space set(搜索空间集合)包含PDCCH的监测时机、搜索空间类型等性质。Search space set一般会绑定CORESET，并且，CORESET包含PDCCH的频域资源和持续时间等性质。
RMSI PDCCH所在的search space set(搜索空间)一般被称为Type0-PDCCH search space set。一般地，由MIB配置的，或者切换等情形下由RRC配置的Type0-PDCCH search space set被称为search space 0(或search space set 0)，所绑定的CORESET被称为CORESET0。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OSI PDCCH的search space set(Type0A-PDCCH search space set)、RAR PDCCH的search space set(Type1-PDCCH search space set)、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。
进一步地，在NR的非授权频谱上，需要定义同步信号块，以便用户设备能够在小区搜索中检测到NR非授权频谱小区。同步信号块可以包含在DRS中，DRS作为包含同步信号块的一个整体；或者不定义DRS，同步信号块独立存在。
在NR非授权频谱上，基站发送DRS或同步信号块前需要进行LBT，只有当监听到信号空闲后，才发送DRS或同步信号块，否则 在某一段时间后，基站再进行LBT。发送DRS或同步信号块是在某个发送窗口内进行的，该发送窗口可以是基站和用户设备约定好的，也可以是RRC信令通过DMTC或者SMTC(同步测量时间配置，Synchronization Measurement Timing Configuration)配置的。
虽然本发明披露如上，但本发明并非限定于此。任何本领域技术人员，在不脱离本发明的精神和范围内，均可作各种更动与修改，因此本发明的保护范围应当以权利要求所限定的范围为准。
