Description

用户设备、基站和相关方法 技术领域
本发明涉及无线通信技术领域，更具体地，本发明涉及用户设备、基站和相关方法。
背景技术
随着移动通信的快速增长和技术的巨大进步，世界将走向一个完全互联互通的网络社会，即任何人或任何东西在任何时间和任何地方都可以获得信息和共享数据。预计到2020年，互联设备的数量将达到500亿部，其中仅有100亿部左右可能是手机和平板电脑，其它的则不是与人对话的机器，而是彼此对话的机器。因此，如何设计系统以更好地支持万物互联是一项需要深入研究的课题。
在第三代合作伙伴计划(3GPP)的长期演进项目(LTE)的标准中，将机器对机器的通信称为机器类型通信(Machine Type Communication，MTC)。MTC是一种不需要人为参与的数据通信服务。大规模的MTC用户设备部署，可以用于安全、跟踪、付账、测量以及消费电子等领域，具体涉及的应用包括视频监控、供货链跟踪、智能电表，远程监控等。MTC要求较低的功率消耗，支持较低的数据传输速率和较低的移动性。目前的LTE系统主要是针对人与人的通信服务。而实现MTC服务的规模竞争优势及应用前景的关键在于LTE网络支持低成本的MTC设备。
另外，一些MTC设备需要安装在居民楼地下室或者由绝缘箔片、金属护窗或者传统建筑物的厚墙保护的位置，相比较LTE网络中常规设备终端(如手机，平板电脑等)，这些设备的空中接口将明显遭受更严重的穿透损失。3GPP决定研究附加20dB覆盖增强的MTC设备的方案设计与性能评估，值得注意的是，位于糟糕网络覆盖区域的MTC设备具有以下特点：非常低的数据传输速率、非常宽松的延时要求以及有限的移动性。针对以上MTC特点，LTE网络可以进一步优化一些信令和/或信道用以更好地支持MTC业务。
在版本13(Rel-13)中定义了一个带宽减小低复杂性(bandwidth-reduced low-complexity，BL)和覆盖增强(coverage-enhanced，CE)的用户设备UE。版本14对版本13定义的BL/CE UE进行增强，以支持更高的数据速率，支持多播业务以及对定位、移动性、eVoLTE功能的支持或增强。2017年3月举行的3GPP RAN#75次全会上，提出了一个新的Rel-15工作项目(参见非专利文献：RP-170732Even further enhanced MTC for LTE，eFeMTC)。该工作项目致力于对版本14的BL/CE UE进一步增强，其目标之一是减少系统获取时间。Rel-15定义的BL/CE UE也可以记为eFeMTC UE。
在2017年3月举行的RAN1#88bis次会议上，提出了几种减少系统获取时间的方法，包括获取主同步信号/辅同步信号PSS/SSS，物理广播信道PBCH，带宽减小低复杂性或覆盖增强UE的系统信息块类型1SIB1-BR和系统信息SI消息的方法。eFeMTC UE获取PSS/SSS的方法包括：(1)基于PSS/SSS或NPSS/NSSS增强PSS/SSS；(2)使用NB-IoT锚载波上传输的NPSS/NSSS。eFeMTC UE获取PBCH的方法包括：(1)基于PBCH或窄带物理广播信道NPBCH增强PBCH；(2)使用NB-IoT锚载波上传输的NPBCH等。
基站如何为eFeMTC UE配置相关信息，使得eFeMTC UE可以使用NB-IoT锚载波上传输的NPSS/NSSS和/或NPBCH获取SIB1-BR，成为需要解决的问题。

锚载波：在NB-IoT中，UE认为窄带主同步性号/窄带辅同步性号/窄带物理广播信道/窄带系统信息块(NPSS/NSSS/NPBCH/SIB-NB)在其上传输的载波。
MIB-NB：即MasterInformationBlock-NB，在BCH上传输的窄带主系统信息块，所述主系统信息块应用于NB-IoT UE。MIB-NB采用固定的调度周期，且在所述周期内重复。在版本14中定义的MIB-NB调度周期为640ms且MIB-NB的第一次传输发生在系统帧号SFN满足SFN mod 64＝0的系统帧的子帧0。在其他无线帧的子帧0重复发送。
SIB1-NB：在版本14中定义的SIB1-NB调度周期为2560ms且SIB1-NB在16个连续无线帧的8个无线帧的子帧4上传输。SIB1-NB第一次传输的起始帧根据小区的物理小区标识确定。SIB1-NB的TBS和在2560ms周期内的重复次数由携带在MIB-NB中的信元schedulingInfoSIB1指示。
SIB1-BR：即SystemInformationBlockType1-BR，应用于BL UE或覆盖增强UE的系统信息块SIB1，其采用固定调度周期。在版本14中，其周期为80ms，SIB1-BR的TBS和在80ms周期内的重复次数由携带在MIB中的信元schedulingInfoSIB1-BR指示。
LTE PCID：LTE小区的物理小区标识。
operationModeInfo：包含在MIB-NB中，信元operationModeInfo用于指示部署场景(in-band/guard-band/standalone)及相关信息。在版本14定义的NB-IoT系统中，根据UE接入的锚载波所属的频段是LTE带内频段、保护带频段还是独立操作模式的频段(例如，GSM频段)，可以分成以下三种操作模式：(1)带内(in-band)，即锚PRB是带内PRB或锚PRB的频段是带内频段；(2)保护带(guard-band)，即锚PRB是保护带PRB或锚PRB位于保护带频段上；(3)独立(stand-alone)，即锚PRB位于适用于独立操作模式的频段(例如，GSM频段)。
Inband-samePCI：所述信元用于指示带内(in-band)部署且NB-IoT和LTE小区共享相同的物理小区标识(physical cell id)且具有相同的NRC和CRS端口数。
Inband-differentPCI：所述信元用于指示带内(in-band)部署且NB-IoT和LTE小区具有不同的物理小区标识。
eutra-CRS-SequenceInfo：所述信元用于指示包含NPSS/NSSS/NPBCH的载波的信息。每个值关联到一个E-UTRA PRB索引，所述E-UTRA PRB索引是与LTE系统中心的偏移且与信道光栅偏移(channel raster offset)有关，具体见表1。所示。其中，

以下描述基站如何为eFeMTC UE配置相关信息，使得eFeMTC UE可以使用NB-IoT锚载波上传输的NPSS/NSSS和/或NPBCH获取SIB1-BR。下面具体描述本发明实施例。
图1示出了根据本公开实施例的用户设备UE中的方法100的流程图。本实施例中的UE可以是例如上述eFeMTC UE。方法100包括以下步骤。
在步骤S110，从基站接收窄带主信息块(MIB-NB，如上所述)。
在步骤S120，根据MIB-NB中指示的操作模式信息，通过以下操作中的至少一项来获得与带宽减小低复杂性或覆盖增强UE的系统信息块类型1(SIB1-BR，如上所述)相关联的配置信息：从MIB-NB中提取所述配置信息的至少部分；以及通过无线资源控制RRC信令从基站接收所述配置信息的至少部分。步骤S120将在以下详细描述。
在步骤S130，基于所述配置信息来获取SIB1-BR。
以下结合具体示例来描述步骤S120的具体操作。
示例1
操作模式信息由operationModeInfo信息单元(如上所述)指示。在步骤S120中，获得配置信息包括：当operationModeInfo信息单元指示inband-samePCI时，从窄带辅同步信号NSSS中提取物理小区标识PCID，并从inband-samePCI中包含的信息单元eutra-CRS-SequenceInfo中提取与LTE系统中心的偏移和信道光栅偏移；以及通过RRC信令从基站接收下行传输带宽和SIB1-BR的调度信息。
具体地，在本示例中，当包含在MIB-NB的信元operationModeInfo值设置为inband-samePCI时，MIB-NB应用于eFeMTC UE。在这种情况下，UE从NSSS中提取PCID，并从inband-samePCI中包含的信息单元eutra-CRS-SequenceInfo中提取与LTE系统中心的偏移和信道光栅偏移(即表1所示信息)。所述MIB-NB可以在NB-IoT锚载波上传输或非锚载波上传输。可选地，基站通过RRC信令为UE配置以下至少一项：下行传输带宽(即LTE小区下行传输带宽)和SIB1-BR的调度信息。本公开所述SIB1-BR的调度信息可以为SIB1-BR的TBS和在一个周期内的重复次数。所述RRC信令可以是MIB-NB，SIB1-NB或其他新定义的系统信息块SIB，所述新定义的系统信息块的调度信息在MIB-NB或SIB1-NB中指示。下行传输带宽和SIB1-BR的调度信息可以包含在一个RRC消 息中，也可以包含在不同的RRC消息中。例如，全部包含在MIB-NB或SIB1-NB或新定义的系统信息块中，也可以一部分部分包含在MIB-NB，另一部分包含在SIB1-NB或新定义的系统信息块中。
优选地，当MIB-NB中的operationModeInfo值不为inband-samePCI时，主系统信息块MasterInformationBlock(MIB)可以应用于eFeMTC UE。
示例2
操作模式信息由operationModeInfo信息单元(如上所述)指示。在步骤S120中，获得配置信息包括：当operationModeInfo信息单元指示inband-differentPCI时，通过RRC信令从基站接收下行传输带宽、SIB1-BR的调度信息、PCID、与LTE系统中心的偏移和信道光栅偏移。
具体地，在本示例中，当包含在MIB-NB的信元operationModeInfo值设置为inband-samePCI或inband-differentPCI时，MIB-NB应用于eFeMTC UE。所述MIB-NB可以在NB-IoT锚载波上传输或非锚载波上传输。
与上述示例1中类似，当包含在MIB-NB的信元operationModeInfo值设置为inband-samePCI时，MIB-NB应用于eFeMTC UE。在这种情况下，UE从NSSS中提取PCID，并从inband-samePCI中包含的信息单元eutra-CRS-SequenceInfo中提取与LTE系统中心的偏移和信道光栅偏移。所述MIB-NB可以在NB-IoT锚载波上传输或非锚载波上传输。可选地，基站通过RRC信令为UE配置以下至少一项：下行传输带宽(即LTE小区下行传输带宽)和SIB1-BR的调度信息。本公开所述SIB1-BR的调度信息可以为SIB1-BR的TBS和在一个周期内的重复次数。所述RRC信令可以是MIB-NB，SIB1-NB或其他新定义的系统信息块SIB，所述新定义的系统信息块的调度信息在MIB-NB或SIB1-NB中指示。下行传输带宽和SIB1-BR的调度信息可以包含在一个RRC消息中，也可以包含在不同的RRC消息中。例如，全部包含在MIB-NB或SIB1-NB或新定义的系统信息块中，也可以一部分部分包含在MIB-NB，另一部分包含在SIB1-NB或新定义的系统信息块中。
此外，当包含在MIB-NB中的信元operationModeInfo值为 inband-differentPCI时，基站通过RRC信令向UE配置读取SIB 1-BR所需要的信息。所述RRC信令可以是MIB-NB，SIB1-NB或其他新定义的系统信息块，所述新定义的系统信息块的调度信息可以在MIB-NB或SIB1-NB中指示。具体地，基站通过RRC信令向UE配置获取SIB1-BR所需要的信息可以采用以下三种示例实现2-1，2-2和2-3。获取SIB1-BR所需要的信息包含用于指示SIB1-BR调度信息和/或下行传输带宽(即LTE小区下行传输带宽)和/或LTE PCID和/或eutra-CRS-SequenceInfo等相关的指示信息(与LTE系统中心的偏移和信道光栅偏移)。
示例实现2-1
基站通过RRC信令向UE配置以下信息中的至少一项：SIB1-BR调度信息、下行传输带宽(即LTE小区下行传输带宽)、LTE PCID、eutra-CRS-SequenceInfo。所述向UE配置的信息可以包含在一个RRC消息中，也可以包含在不同的RRC消息中。例如，全部包含在MIB-NB或SIB1-NB或新定义的系统信息块中，也可以一部分部分包含在MIB-NB，另一部分包含在SIB1-NB或新定义的系统信息块中。例如，SIB1-BR调度信息、下行传输带宽等包含在MIB-NB中，其他的信息包含在SIB1-NB或其他新定义的系统信息块中。
示例实现2-2
下行传输带宽、与LTE系统中心的偏移和信道光栅偏移可以由单个信息单元(称为eutra-CRS-SequenceInfo-Extend)联合指示。
具体地，基站通过RRC信令向UE配置以下信息中的至少一项：SIB1-BR调度信息、LTE PCID以及用于指示下行传输带宽(即LTE小区下行传输带宽)、信道光栅偏移、与LTE系统中心偏移的指示信息。所述指示信息记为信元eutra-CRS-SequenceInfo-Extend。所述RRC信令可以是MIB-NB，SIB1-NB或其他新定义的系统信息块，所述新定义的系统信息块的调度信息可以在MIB-NB或SIB1-NB中指示。下所述向UE配置的信息可以包含在一个RRC消息中，也可以包含在不同的RRC消息中。例如，全部包含在MIB-NB或SIB1-NB或新定义的系统信息块中，也可以一部分部分包含在MIB-NB，另一部分包含在SIB1-NB或新 定义的系统信息块中。例如，SIB1-BR调度信息、eutra-CRS-SequenceInfo-Extend包含在MIB-NB中，其他的信息包含在SIB1-NB或其他新定义的系统信息块中。
表2中给出了信元eutra-CRS-SequenceInfo-Extend一种表示方式。信元eutra-CRS-SequenceInfo-Extend可以用6比特表示，用于指示包含NPSS/NSSS/NPBCH的载波的信息，具体可包括下行传输带宽、信道光栅偏移和与LTE系统中心偏移。每个值关联到一个E-UTRA物理资源块PRB索引，所述E-UTRA PRB索引是与LTE系统中心的偏移且与信道光栅偏移(channel raster offset)和下行传输带宽有关，具体见表2。
