Description

一种系统信息的传输方法及装置、终端设备 技术领域
本申请实施例涉及移动通信技术领域，具体涉及一种系统信息的传输方法及装置、终端设备。
背景技术
目前，如果专用带宽部分(Band Width Part，BWP)上配置了公共搜索空间，则终端设备需要在公共搜索空间内接收系统信息。
一个比较重要的系统信息是剩余最小系统信息(Remaining Minimum System Information，RMSI)。对于RMSI来说，规定了搜索空间为0公共搜索空间(公共搜索空间#0)的时候，如何接收RMSI的物理下行控制信道(Physical Downlink Control Channel，PDCCH)，简称为RMSI PDCCH。而对于专用BWP上配置了公共搜索空间，且RMSI的搜索空间不是0公共搜索空间的场景下，如何在该专用BWP上接收RMSI PDCCH是不明确的。
发明内容
本申请实施例提供一种系统信息的传输方法及装置、终端设备。
本申请实施例提供的系统信息的传输方法，包括：
终端设备确定RMSI PDCCH时机和同步信号块(SS/PBCH Block，SSB)索引之间的对应关系，所述RMSI PDCCH时机用于传输RMSI PDCCH；
所述终端设备基于所述RMSI PDCCH时机和SSB索引之间的对应关系，在专用BWP上的第一搜索空间内接收RMSI PDCCH；其中，所述第一搜索空间为所述专用BWP上配置的非0公共搜索空间，所述RMSI PDCCH时机基于所述第一搜索空间的配置信息确定。
本申请实施例提供的系统信息的传输装置，应用于终端设备，所述装置包括：
确定单元，用于确定RMSI PDCCH时机和SSB索引之间的对应关系，所述RMSI PDCCH时机用于传输RMSI PDCCH；
接收单元，用于基于所述RMSI PDCCH时机和SSB索引之间的对应关系，在专用BWP上的第一搜索空间内接收RMSI PDCCH；其中，所述第一搜索空间为所述专用BWP上配置的非0公共搜索空间，所述RMSI PDCCH时机基于所述第一搜索空间的配置信息确定。
本申请实施例提供的终端设备，包括处理器和存储器。该存储器用于存储计算机程序，该处理器用于调用并运行该存储器中存储的计算机程序，执行上述的系统信息的传输方法。
本申请实施例提供的芯片，用于实现上述的系统信息的传输方法。
具体地，该芯片包括：处理器，用于从存储器中调用并运行计算机程序，使得安装有该芯片的设备执行上述的系统信息的传输方法。
本申请实施例提供的计算机可读存储介质，用于存储计算机程序，该计算机程序使得计算机执行上述的系统信息的传输方法。
本申请实施例提供的计算机程序产品，包括计算机程序指令，该计算机程序指令使得计算机执行上述的系统信息的传输方法。
本申请实施例提供的计算机程序，当其在计算机上运行时，使得计算机执行上述的系统信息的传输方法。
通过上述技术方案，在专用BWP上配置了公共搜索空间，且RMSI的搜索空间为非0公共搜索空间的情况下，终端设备可以明确RMSI PDCCH时机和SSB索引之间的对应关系，由于SSB索引与波束之间具有关联关系，因而终端设备可以确定出RMSI PDCCH时机和波束之间的对应关系，从而基于该对应关系在专用BWP上的非0公共搜索空间内接收RMSI PDCCH，确保了终端设备在正确的位置(即通过正确的波束)接收RMSI PDCCH，为后续正确接收RMSI以及获得小区提供的服务提供了保障。

为便于理解本申请实施例的技术方案，以下对本申请实施例相关的技术方案进行说明。
随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性、复杂性，为此第三代合作伙伴计划(3 rd Generation Partnership Project，3GPP)国际标准组织开始研发5G。5G的主要应用场景为：增强移动超宽带(enhanced Mobile Broadband，eMBB)、低时延高可靠通信(Ultra-Reliable Low-Latency Communications，URLLC)、大规模机器类通信(massive Machine-Type Communications，mMTC)。
一方面，eMBB仍然以用户获得多媒体内容、服务和数据为目标，其需求增长十分迅速。另一方面，由于eMBB可能部署在不同的场景中，例如室内，市区，农村等，其能力和需求的差别也比较大，所以不能一概而 论，必须结合具体的部署场景详细分析。URLLC的典型应用包括：工业自动化，电力自动化，远程医疗操作(手术)，交通安全保障等。mMTC的典型特点包括：高连接密度，小数据量，时延不敏感业务，模块的低成本和长使用寿命等。
在NR早期部署时，完整的NR覆盖很难获取，所以典型的网络覆盖是广域的LTE覆盖和NR的孤岛覆盖模式。而且大量的LTE部署在6GHz以下，可用于5G的6GHz以下频谱很少。所以NR必须研究6GHz以上的频谱应用，而高频段覆盖有限、信号衰落快。同时为了保护移动运营商前期在LTE投资，提出了LTE和NR之间紧耦合(tight interworking)的工作模式。
NR将来会部署在高频上，为了提高覆盖，在5G中，通过引入波束扫描(beam sweeping)的机制来满足覆盖的需求(用空间换覆盖，用时间换空间)，如图2所示。在引入beam sweeping后，每个波束方向上都需要发送同步信号，5G的同步信号以SSB的形式给出，包含主同步信号(Primary Synchronisation Signal，PSS)、辅同步信号(Secondary Synchronisation Signal，SSS)、和物理广播信道(Physical Broadcast Channel，PBCH)，如图3所示。5G的同步信号以同步信号突发组(SS burst set)的形式在时域上周期性出现，如图4所示。
每个小区的实际传输的beam个数通过网络侧配置来确定，但是小区所在的频点决定了可以配置最多的beam个数，如下表1所示。
频率范围 L(最多的beam个数)
up to 3(2.4)GHz 4
3(2.4)GHz—6GHz 8
6GHz—52.6GHz 64
表1
在5G中，最大的信道带宽可以是400MHZ(称为宽带载波(wideband carrier))，相比于LTE最大20M带宽来说，宽带载波的带宽很大。如果终端设备保持工作在宽带载波上，则终端设备的功率消耗非常大。所以建议终端设备的射频(Radio Frequency，RF)带宽可以根据终端设备实际的吞吐量来调整。为此，引入BWP的概念，BWP的动机是优化终端设备的功率消耗。例如终端设备的速率很低，可以给终端设备配置小一点的BWP，如果终端设备的速率要求很高，则可以给终端设备配置大一点的BWP。如果终端设备支持高速率，或者工作在载波聚合(Carrier Aggregation，CA)模式下，可以给终端设备配置多个BWP。
RRC空闲状态或者RRC非激活状态的终端设备驻留在初始BWP(initial BWP)上，这个初始BWP对于RRC空闲状态或者RRC非激活状 态的终端设备是可见的，终端设备可以在初始BWP上获取系统信息、寻呼(paging)等信息。
对于RRC连接状态的终端设备，通过无线资源控制(Radio Resource Control，RRC)专用信令可以给一个终端配置最多4个上行BWP和最多4个下行BWP，但同一时刻只能有一个上行BWP和下行BWP被激活。在RRC专用信令中，可以指示所配置的BWP中第一个激活的BWP。同时在终端设备处于连接态过程中，也可以通过下行控制信息(Downlink Control Information，DCI)在不同的BWP之间切换。当处于非激活状态的载波进入激活状态后，第一个激活的BWP为RRC专用信令中配置的第一个激活的BWP。
如果在专用BWP上配置了公共搜索空间，则终端设备需要在该专用BWP上的公共搜索空间内接收系统信息和寻呼。
在NR中，系统信息注意包括主信息块(Master Information Block，MIB)、系统信息块(System Information Block)SIB1以及其他SIB(Other System Information，OSI)。其中，MIB也称为最小系统信息(Minimum System Information，MSI)，SIB1也称为RMSI。进一步，其他SIB包括：SIB2、SIB3、SIB4、SIB5、SIB6、SIB7、SIB8、SIB9。以下表2给出了各个系统信息承载的主要内容。
Figure PCTCN2021091656-appb-000001
表2
MIB在PBCH上传输，与PSS和SSS组成SSB。SIB1(即RMSI)和OSI采用动态调度的方式通过物理下行共享信道(Physical Downlink Shared Channel，PDSCH)传输。RMSI的调度的搜索空间一般通过MIB配置，即公共搜索空间#0(也可以简称为搜索空间#0)。OSI的调度的搜索空间通过SIB1配置，如果没有配置则默认使用和RMSI相同的搜索空间，即搜索空间#0。
由于NR中采用波束扫描方式传输。所以RMSI和OSI也是采用波束扫描方式传输，需要说明的是，终端设备假定SSB和RMSI PDCCH，OSI  PDCCH是准供址(QCL)的。
RMSI的PDCCH，简称为RMSI PDCCH，RMSI PDCCH的配置信息在MIB中配置，RMSI PDCCH和SSB之间的复用关系有复用图样1(multiplexing pattern 1)，复用图样2(multiplexing pattern 2)，复用图样3(multiplexing pattern 3)。所以RMSI PDCCH时机和SSB之间有一对一的对应关系。
OSI的PDCCH，简称为SI PDCCH，SI PDCCH的配置信息在SIB1中配置。1)在SIB1中如果searchSpaceOtherSystemInformation等于0或者不配置，则SI PDCCH默认使用RMSI PDCCH的配置信息。2)在SIB1中如果searchSpaceOtherSystemInformation不等于0，则：
I)SI PDCCH时机在SI窗口内从1连续编号。
II)第[x*N+K]个SI PDCCH时机对应第K个实际传输的SSB；其中，x＝0,1,...X-1，K＝1,2,…N；X为SI窗口内重复传输的SI的次数，N是实际传输的SSB的个数。
这里，X的取值满足以下公式：X＝CEIL(SI窗口内的SI PDCCH时机的总数/N)；其中，CEIL为向上取整运算。
目前，只规定了RMSI的搜索空间为公共搜索空间#0的时候，RMSI PDCCH时机和SSB之间的映射关系。而对于专用BWP上配置了公共搜索空间，且RMSI的搜索空间不是公共搜索空间#0的场景下，如何在该专用BWP上接收RMSI PDCCH是不明确的。
为此，提出了本申请实施例的以下技术方案。本申请实施例的技术方案旨在对于专用BWP上配置了公共搜索空间，且RMSI的搜索空间被配置为非0公共搜索空间的场景下，确定RMSI PDCCH时机和SSB之间的对应关系，并基于该对应关系接收RMSI PDCCH。
图5是本申请实施例提供的系统信息的传输方法的流程示意图，如图5所示，所述系统信息的传输方法包括以下步骤：
步骤501：终端设备确定RMSI PDCCH时机和SSB索引之间的对应关系，所述RMSI PDCCH时机用于传输RMSI PDCCH。
步骤502：所述终端设备基于所述RMSI PDCCH时机和SSB索引之间的对应关系，在专用BWP上的第一搜索空间内接收RMSI PDCCH；其中，所述第一搜索空间为所述专用BWP上配置的非0公共搜索空间，所述RMSI PDCCH时机基于所述第一搜索空间的配置信息确定。
本申请实施例中，RMSI PDCCH时机是指RMSI PDCCH时机，RMSI PDCCH时机用于传输RMSI PDCCH，RMSI PDCCH用于调度RMSI传输，或者说RMSI PDCCH用于承载RMSI的调度信息。
需要说明的是，本申请实施例中的RMSI PDCCH时机也可以称为RMSI PDCCH监听时机(PDCCH monitor occasion)。
本申请实施例中，RMSI传输采用beam sweep方式传输，为了保证终 端设备正确接收RMSI，需要正确接收调度RMSI传输的RMSI PDCCH，因此，需要确定RMSI PDCCH时机与SSB之间的对应关系。这里，在确定RMSI PDCCH时机与SSB之间的对应关系之前，引入RMSI窗口的概念。
在本申请一些可选实施方式中，所述终端设备获取第二配置信息，所述第二配置信息用于确定所述RMSI窗口。
在本申请一些可选实施方式中，所述终端设备确定RMSI窗口的起始SFN为满足以下公式的SFN：SFN mod M＝0；其中，mod为取余运算，M为RMSI窗口的长度对应的SFN个数。作为示例，所述M的取值为16，相应地，RMSI窗口的长度为16个连续SFN的长度。
在本申请一些可选实施方式中，所述终端设备确定所述RMSI窗口的长度是RMSI重复周期的整数倍。
在本申请一些可选实施方式中，在一个所述RMSI窗口内，RMSI窗口的起始边界为该RMSI窗口内第一个RMSI重复周期的起始边界，RMSI窗口内的所有RMSI重复周期连续排列。
需要说明的是，RMSI窗口的长度，也即是RMSI周期。在一个示例中，RMSI窗口的长度为160ms。在一个示例中，RMSI重复周期为20ms。
以下分情况对如何确定RMSI PDCCH时机与SSB之间的对应关系进行说明。
情况一
在RMSI窗口内，所述RMSI PDCCH时机从0开始编号。所述终端设备确定所述RMSI窗口内的第k-1个RMSI PDCCH时机索引对应第k个实际传输的SSB；其中，k为大于等于1且小于等于S的正整数；S为实际传输的SSB的个数，实际传输的SSB按照SSB索引升序从1开始编号。
进一步，对于RMSI窗口内有RMSI重复传输的情况，所述终端设备确定所述RMSI窗口内的第S*n+k-1个RMSI PDCCH时机索引对应第n+1次重复传输的第k个实际传输的SSB；其中，n为大于等于0且小于等于N-1的正整数，k为大于等于1且小于等于S的正整数；S为实际传输的SSB的个数，实际传输的SSB按照SSB索引升序从1开始编号，N为所述RMSI窗口内重复传输的RMSI的次数。
在一些可选实施方式中，所述N的取值满足以下公式：N＝CEIL(RMSI窗口内的RMSI PDCCH时机的总数/S)；其中，CEIL为向上取整运算。举个例子：RMSI窗口内的RMSI PDCCH时机的总数为12，S为4，那么，N的取值为3。
需要说明的是，第X个RMSI PDCCH时机索引对应的编号为X，换句话说，编号为X的RMSI PDCCH时机索引为第X个RMSI PDCCH时机索引。
