Description

一种速率匹配方法、网络设备以及用户设备
本申请要求于2019年11月26日提交中国专利局、申请号为201911175252.7、发明名称为“一种速率匹配方法、网络设备以及用户设备”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
本申请涉及通信领域，尤其涉及一种速率匹配方法、网络设备以及用户设备。
背景技术
在长期演进(long term evolution，LTE)制式和新电波(new radio，NR)制式的频谱共享场景(LTE NR，LNR)中，LTE制式和NR制式两种制式需要共享同一段频谱资源。其中，NR制式的协议规定其用户设备(user equipment，UE)需支持小区参考信号(cell reference signal，CRS)的速率匹配(ratematching)功能，以提升LNR频谱共享的性能。
当前，NR的协议定义了用户设备的CRS相关功能是通过无线资源控制(radio resource control，RRC)信令配置通知的。根据协议(TS 38.331)定义，网络设备给用户设备下发关于CRS进行速率匹配的相关配置信息携带在RRCSetup消息、RRCReconfiguration消息或RRCResume消息中。但是在独立组网(standalone，SA)的场景中，对支持速率匹配功能的用户设备，UE接收到关于CRS进行速率匹配的相关配置信息之前，无法进行速率匹配以进行打孔避让，造成用户设备在进行速率匹配之前，接收到的消息都会受到来自使用LTE指示的网络设备发送的CRS的干扰，影响用户设备与网络设备建立的正常连接。
为了避免这种影响，当前，使用LTE制式的网络设备在分配给用户设备接入的资源块(resource block，RB)时不发送CRS，但是这样对LTE制式的性能造成恶化影响，甚至影响LTE制式下一些用户设备的解调性能。
发明内容
本申请实施例提供了一种速率匹配方法、网络设备以及用户设备，用于通过检测CRS打孔分布图样以进行速率匹配。
本申请第一方面提供了一种速率匹配方法，用于新电波NR制式和长期演进LTE制式的频谱共享场景中，NR制式网络设备向用户设备发送打孔使能信息，若用户设备支持速率匹配功能，那么用户设备接收打孔使能信息后，可以检测LTE制式网络设备下的CRS打孔分布图样，并根据检测到的CRS打孔分布图样进行速率匹配，使得在不影响LTE制式的LTE制式网络设备发送CRS的情况下，避免了LTE制式网络设备发送CRS的干扰，而不影响用户设备与NR制式网络设备建立的正常连接。
在一些可能的实现方式中，打孔使能信息为备用spare位被置位的NR制式主系统信息块MIB,按照系统实现，在LNR频谱共享场景下，NR制式网络设备下发的NR制式MIB所使用的时频资源上，LTE制式网络设备需要进行打孔避让，因此NR制式MIB是不会受到干扰的。
在一些可能的实现方式中，用户设备接收打孔使能信息后，对LTE制式下的各种可能 CRS打孔分布图样进行盲打孔匹配解调，得到CRS打孔分布图样。在LNR频谱共享的场景下，通常使用的两发射两接收(2 transmit 2 receive，2T2R)或四发射四接收(4 transmit 4 receive，4T4R)的设置。当LTE制式网络设备发送CRS时，由于天线端口数可能为2种(2/4)，而物理小区标识(physical cell identifier，PCI)对3进行求余可以得到3种情况(0/1/2)，那么在各个资源块(resource block，RB)上最多可能出现如图2-3和图2-4所示的一共6种CRS打孔分布图样。那么，用户设备分别按照上面的各种可能的CRS打孔分布图样尝试进行打孔，并将得到的数据信号进行解调。
在一些可能的实现方式中，用户设备接收打孔使能信息后，获取LTE制式网络设备发送的LTE制式MIB，然后从LTE制式MIB中获取循环冗余校验CRC掩码序列，并根据CRC掩码序列确定天线端口数，最后对天线端口数的前提下的各种可能CRS打孔分布图样进行盲打孔匹配解调，得到CRS打孔分布图样。得到LTE小区参数信号的天线端口数后，如果天线端口数为2，则盲检如图2-3中的3种CRS打孔分布图样，如果天线端口数为4，则盲检如图2-4中的3种CRS打孔分布图样，即此时需要盲检的CRS打孔分布图样只有三种，进一步缩小了用户设备需要盲检的次数。
在一些可能的实现方式中，若用户设备不支持速率匹配功能，则很可能会产生干扰，则用户设备接收打孔使能信息后，通过NR制式之外的制式连接NR制式网络设备，或连接NR制式网络设备之外的其他网络设备。

在一些可能的实现方式中，打孔使能信息为备用spare位被置位的NR制式主系统信息块MIB。
在一些可能的实现方式中，收发器接收打孔使能信息后，处理器，还用于对LTE制式下的各种可能CRS打孔分布图样进行盲打孔匹配解调，得到CRS打孔分布图样。
在一些可能的实现方式中，收发器接收打孔使能信息后，处理器，还用于接收打孔使能信息后，获取LTE制式网络设备发送的LTE制式MIB，从LTE制式MIB中获取CRC掩码序列，根据CRC掩码序列确定天线端口数，最后对天线端口数的前提下的各种可能CRS打孔分布图样进行盲打孔匹配解调，得到CRS打孔分布图样。
在一些可能的实现方式中，若用户设备不支持速率匹配功能，则收发器接收打孔使能信息后，处理器还用于通过NR制式之外的制式连接NR制式网络设备，或连接NR制式网络设备之外的其他网络设备。
本申请第四方面提供了一种用户设备，用于NR制式和LTE制式的频谱共享场景中，包括：收发器，用于向用户设备发送打孔使能信息。

具体实施方式
本申请实施例提供了一种速率匹配方法、网络设备以及用户设备，用于NR制式和LTE制式的频谱共享场景中，通过检测CRS打孔分布图样进行速率匹配。
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。
本申请可以应用到如图1所示的通信系统100上，该通信系统100包括网络设备110和多个用户设备(user equipment，UE)120。
网络设备110可以是LTE制式和/或NR制式或者授权辅助接入长期演进(authorized auxiliary access long-term evolution，LAA-LTE)系统中的演进型基站(evolutional node b，e-nodeB)宏基站、微基站(也称为“小基站”)、微微基站、接入站点(access point，AP)、传输站点(transmission point，TP)或新一代基站(new generation node b，gNodeB)等。在本申请实施例中，网络设备110可以是LNR制式，即同时是LTE制式和NR制式。在本申请实施例中，以同时是LTE制式和NR制式为例进行说明。
需要说明的是，NR制式是基于正交频分复用(orthogonal frequency division multiplexing，OFDM)的全新空口设计的全球性5G标准，也是下一代非常重要的蜂窝移动技术基础，5G技术将实现超低时延、高可靠性。而LTE是由第三代合作伙伴计划(the 3rd generation partnership project，3GPP)组织制定的通用移动通信系统(universal mobile telecommunications system，UMTS)技术标准的长期演进,LTE系统引入了OFDM和多输入多输出(multi-input&multi-output，MIMO)等关键技术，显著增加了频谱效率和数据传输速率，主要用于4G标准。
UE 120可为移动台(mobile station，MS)、移动终端(mobile terminal)、智能终端等，该UE 120可以经网络设备110与一个或多个核心网进行通信。例如，UE 120可以是移动电话(或称为“蜂窝”电话)、具有移动终端的计算机等，UE 120还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置以及未来NR网络中的UE 120，它们与网络设备110交换语音或数据。本申请中，UE 120还可以包括中继设备，和基站可以进行数据通信的都可以看为UE 120，本申请中将以一般意义上的UE来介绍。在一些可行的实现方式中，UE 120还可以为车辆对基础设施/车辆/行人(vehicle to infrastructure/vehicle/pedestrian，V2X)系统中的车辆。
在LTE制式和NR制式的LNR频谱共享场景中，NR制式的协议规定其用户设备(user equipment，UE)需支持小区参考信号(cell reference signal，CRS)的速率匹配(ratematching)功能，以提升LNR频谱共享的性能。
当前，NR的协议定义了用户设备的CRS相关功能是通过无线资源控制(radio resource control，RRC)信令配置通知的。根据协议(TS 38.331)定义，网络设备给用户设备下发关于CRS进行速率匹配的相关配置信息携带在RRCSetup消息、RRCReconfiguration消息或RRCResume消息中。但是在独立组网(standalone，SA)的场景中，对支持速率匹配功能的用户设备，UE接收到关于CRS进行速率匹配的相关配置信息之前，无法进行速率匹配以进行打孔避让，造成用户设备在进行速率匹配之前，接收到的消息都会受到来自使用LTE指示的网络设备发送的CRS的干扰，影响用户设备与网络设备建立的正常连接。
为了避免这种影响，当前，使用LTE制式的网络设备在分配给用户设备接入的资源块(resource block，RB)时不发送CRS，但是这样对LTE制式的性能造成恶化影响，甚至影响LTE制式下一些用户设备的解调性能。
在本申请实施例中，NR制式网络设备向用户设备发送打孔使能信息，若用户设备支持速率匹配功能，那么用户设备接收打孔使能信息后，可以检测LTE制式网络设备下的CRS打孔分布图样，并根据检测到的CRS打孔分布图样进行速率匹配，使得在不影响LTE制式的LTE制式网络设备发送CRS的情况下，避免了LTE制式网络设备发送CRS的干扰，而不影响用户设备与NR制式网络设备建立的正常连接。
请参考图2-1，为本申请实施例提供的一种速率匹配方法，用于NR制式和LTE制式的频谱共享场景中，通过检测CRS打孔分布图样进行速率匹配，所述方法包括：
201、NR制式网络设备向用户设备发送打孔使能信息。
在一些可行的实施例中，NR制式网络设备可以向用户设备发送打孔使能信息，以使得用户设备进行对LTE发送的CRS进行速率匹配，以打孔避让，避免干扰。需要说明的是，速率匹配是指传输信道上的比特被重复或者被打孔，以匹配物理信道的承载能力，信道映射时达到传输格式所要求的比特速率。打孔就是依照一定的模式把一些比特打掉，从比特序列中移除。如果输入比特数多于输出比特数，那就是用打孔；如果输入比特数少于输出比特数，那就是用重复，重复就是在当前比特和后面的比特之间插入一次当前比特。
如图2-2所示，NR制式的协议中的NR制式MIB的消息格式中，包含系统帧号、小区接入状态、是否允许频间重选等，但是保留了有1比特保留，作为备用(spare)位，在本申请实施例中，在NR制式网络设备发送的NR制式MIB中，将spare位被置位，用于通知LNR频谱共享的场景下的用户设备启用速率匹配功能。
需要说明的是，按照系统实现，在LNR频谱共享场景下，NR制式网络设备下发的NR制式MIB所使用的时频资源上，LTE制式网络设备需要进行打孔避让，因此NR制式MIB是不会受到干扰的。
202、若用户设备支持速率匹配功能，则用户设备接收打孔使能信息后，检测LTE制式网络设备下的CRS打孔分布图样。
在本申请实施例中，若用户设备支持速率匹配功能，则用户设备接收打孔使能信息后，检测LTE制式网络设备下的CRS打孔分布图样。具体的，用户设备可以通过两种方法来检测该CRS打孔分布图样，以下分别进行说明。
方法一、盲检。
用户设备接收到NR制式网络设备发送的MIB消息后对其进行解析，获取其中的spare位的信息。若确定spare位被置位，则认为接收到打孔使能信息，则该用户设备可以对LTE制式下的各种可能CRS打孔分布图样分别进行打孔匹配解调。
在LNR频谱共享的场景下，通常使用的两发射两接收(2 transmit 2 receive，2T2R)或四发射四接收(4 transmit 4 receive，4T4R)的设置。当LTE制式网络设备发送CRS时，由于天线端口数可能为2种(2/4)，而物理小区标识(physical cell identifier，PCI)对3进行求余可以得到3种情况(0/1/2)，那么在各个资源块(resource block，RB)上最多可能出现如图2-3和图2-4所示的一共6种CRS打孔分布图样。那么，用户设备分 别按照上面的各种可能的CRS打孔分布图样尝试进行打孔，并将得到的数据信号进行解调。如果对某种CRS打孔分布图样能够正确的解析出后续的数据，那么可以认为盲检成功，则确定该种CRS打孔发布图样是正确的。在一些可行的实施例中，天线端口数也可能为1种，那么需要尝试打孔的数量增加3种。由于1个天线端口数的用户设备已经逐步淘汰，本申请实施例中，以2或4的是天线端口数为例进行说明。
方法二、检测LTE制式网络设备发送的LTE制式MIB。
对于方法二，可以通过以下三个步骤实现：
步骤1、用户设备接收打孔使能信息后，获取LTE制式网络设备发送的LTE制式MIB。
在LNR频谱共享场景下，连接NR制式网络设备的用户设备可以获取LTE制式网络设备发送的LTE制式MIB。
步骤2、用户设备从LTE制式MIB中确定循环冗余校验(Cyclic Redundancy Check，CRC)掩码序列，并根据CRC掩码序列确定天线端口数。
需要说明的是，如下表1所示，承载LTE制式MIB的物理广播信道(physical broadcast channel，PBCH)所使用的CRC掩码序列，是根据天线端口数来选择的，那么在本申请实施例中，用户设备可以从LTE制式MIB中确定循环冗余校验(Cyclic Redundancy Check，CRC)掩码序列，并根据CRC掩码序列确定天线端口数。
基站侧的传输天线端口数目 PBCH CRC  掩码
1 <0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0>
2 <1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1>
4 <0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1>
表1 PBCH CRC掩码
需要说明的是，CRC掩码序列是一种根据网络数据包或计算机文件等数据产生简短固定位数校验码的一种信道编码技术，主要用来检测或校验数据传输或者保存后可能出现的错误。它是利用除法及余数的原理来作错误侦测的。
步骤3、用户设备根据天线端口数盲检的各种可能CRS打孔分布图样。
得到LTE小区参数信号的天线端口数，方法一中的分析，如果天线端口数为2，则盲检如图2-3中的3种CRS打孔分布图样，如果天线端口数为4，则盲检如图2-4中的3种CRS打孔分布图样，即此时需要盲检的CRS打孔分布图样只有三种，进一步缩小了用户设备需要盲检的次数。
203、用户设备根据CRS打孔分布图样进行速率匹配。
当确定了CRS打孔分布图样后，用户设备可以用于进行速率匹配。
在本申请实施例中，通过NR制式网络设备向用户设备发送打孔使能信息，若用户设备支持速率匹配功能，那么用户设备接收打孔使能信息后，可以检测LTE制式网络设备下的CRS打孔分布图样，并根据检测到的CRS打孔分布图样进行速率匹配，使得在不影响LTE制式的LTE制式网络设备发送CRS的情况下，避免了由于LTE制式的CRS干扰，以使得UE可以与NR制式网络设备建立正常连接。

302、若用户设备不支持速率匹配功能，则用户设备接收打孔使能信息后，通过NR制式之外的制式连接NR制式网络设备，或连接NR制式网络设备之外的其他网络设备。
若用户设备不支持速率匹配功能，则很可能会产生干扰，在本申请实施例中，那么该用户设备可以通过NR制式之外的制式连接NR制式网络设备，如LTE制式，或者连接NR制式网络设备之外的其他使用NR制式的网络设备。
