Description

一种信息的指示方法及装置、计算机存储介质 技术领域
本发明涉及无线通信技术领域,尤其涉及一种信息的指示方法及装置、计算机存储介质。
背景技术
免授权频谱是国家和地区划分的可用于无线电设备通信的频谱,该频谱通常被认为是共享频谱,即不同通信系统中的通信设备只要满足国家或地区在该频谱上设置的法规要求,就可以使用该频谱,不需要向政府申请专有的频谱授权。第三代合作伙伴计划(3GPP,3rd Generation Partnership Project)计划引入新空口免授权(NR unlicensed)技术,用于在免授权频谱上使用新空口(NR,New Radio)技术进行通信。
免授权频段与授权频段存在一些重叠部分,出于不同的考虑,不同的国家的频谱监管以及分配机构对于频谱的规划与分配有不同,例如3.5GHz在中国为授权的NR频段,而在美国则为免授权频段;类似地,37GHz中国为可能会划分为授权的NR频段,而在美国则可能会划分为免授权频段。上述频谱分配上的差异可能会导致终端在不同的国家或地区漫游时,在同一频段上(如3.5GH频段上),有的国家或地区部署的为NR unlicensed系统,而有的国家或地区部署的为新空口授权(NR licensed)系统。尤其对于支持Standalone NR unlicensed的终端设备,可能从接受同步信号块(SSB,Synchronization Signal Block)本身并不能区分接入的系统为授权载波系统还是免授权载波系统,终端设备无法确认后续按照那种方式进行信号的发送和接收。

具体实施方式
为便于理解本发明实施例的技术方案,以下对本发明实施例相关的技术进行说明。
1)第五代通信系统(5G,5 th Generation)中的波束发送
在5G系统中,由于采用的频段相比长期演进(LTE,Long Term Evolution)更高,无线信号传输的路径损耗变大,无线信号的覆盖变小。此时,通过基站的多天线系统,采用波束成形(beamforming)技术形成波束来提高无线信号的增益来弥补路径损耗是一种可行的方法。波束具有方向性,一个窄波束只能覆盖小区的部分区域,无法覆盖小区中的所有用户。如图1所示,基站可以通过4个不同方向的波束发送信号,对于波束B2,只能覆盖用户设备(UE,User Equipment)1,UE2无法覆盖。
5G NR系统中的公共信道和信号,如同步信号和广播信道,需要通过多波束扫描的方式覆盖整个小区,便于小区内的UE接收。同步信号(SS,Synchronization Signal)的多波束发送是通过定义SS突发组(SS burst set)实现的。一个SS burst set包含一个或者多个SS突发(SS burst),一个SS burst包含一个或多个SS块(SS block,也可以简称为SSB)。一个SS block用于承载一个波束的同步信号和广播信道。因此,一个SS burst set可以包含小区内SS block数量个波束的同步信号。一个SS block中包含一个符号的主同步信号(PSS,Primary Synchronization Signal),一个符号的辅同步信号(SSS,Secondary Synchronization Signal)和两个符号的新空口-物理广播信道(NR-PBCH,New Radio Access Technology-Physical Broadcast Channel),如图2所示。
SS burst set的周期可配置,并且一个周期内发送的SS burst set承载在5ms的时间窗内发送。以15kHz子载波间隔为例,一个时隙(slot)包含14个符号(symbol),可以承载两个SS block。
除了同步信号和PBCH需要进行多波束扫描,其他的一些公共信息,如剩余最小系统信息(RMSI,Remaining Minimum System Information),寻呼(paging)消息,也需要通过多波束扫描的方式发送。
2)控制资源集(CORESET,Control Resource Set)
在5G NR系统中,对于初始接入的UE,需要定义一个公共搜索空间(common search space)用于接收公共控制信息,例如RMSI。因此,引入了CORESET的概念,用于定义承载控制信息的资源集合,UE在该资源集合中检测新空口-物理下行控制信道(NR-PDCCH,New Radio Access Technology-Physical Downlink Control Channel)信道,以获得承载RMSI的新空口-物理下行共享信道(NR-PDSCH,New Radio Access  Technology-Physical Downlink Shared Channel)的调度信息。RMSI对应的CORESET的指示信息承载在NR-PBCH中的RMSI-PDCCH-Config信息域中,用于UE接收RMSI。CORESET的配置信息主要包含以下信息:
·频域资源
·起始正交频分复用(OFDM,Orthogonal Frequency Division Multiplexing)符号
·时间长度
3)NR-PBCH中关于RMSI的CORESET信息
当UE需要接入网络时,需要从网络获取系统消息,其中一部分通过NR-PBCH承载,一部分通过NR-PDSCH承载,通过NR-PDSCH承载的系统消息包括RMSI。NR-PDSCH对应的下行控制信息(DCI,Downlink Control Information)承载在NR-PDCCH上,而NR-PDCCH的所在的时频资源位置通过NR-PBCH承载的CORESET信息来指示,即Type0-PDCCH common search space信息。同时,NR-PBCH中还承载用于指示该SS block是否关联RMSI或者Type0-PDCCH common search space的信息,即RMSI presence flag信息。该RMSI presence flag信息通过PRB grid offset信息域中的保留值指示当前SS block不关联RMSI或者Type0-PDCCH common search space。PRB grid offset信息域包括4或者5比特,用于指示同步信号块与非同步信号块的信道或信号之间的物理资源块(PRB)栅格(grid)之间的偏移,该偏移包括0-11或者0-23个子载波。因此,PRB grid offset信息域还包括4个或者8个保留值可以用于指示当前SS block不关联RMSI或者Type0-PDCCH common search space。
RMSI-PDCCH-Config信息通过8比特指示。当PRB grid offset信息域指示当前SS block不关联RMSI或者Type0-PDCCH common search space时,该RMSI-PDCCH-Config信息域用于指示同步信号块的频域位置信息,便于UE减少盲检测,根据该同步信号块的频域位置信息,从而检测同步信号块中的PBCH以获得RMSI-PDCCH-Config信息,从而进一步接收RMSI。
4)同步栅格(raster)
对于NR中的无线频谱,同步信号块的频域位置通过同步raster来定义,如下表1所示,在不同的频率范围,同步信号块的可能的频域位置通过表中公式来确定,并且通过SSREF来进行编号。
Figure PCTCN2018081468-appb-000001
表1
确定了同步raster之后,同步信号块的资源映射根据下表2确定。即同步raster位于同步信号块的20个PRB中的PRB编号为10的PRB中的编号0的RE。
RE索引k 0
SSB对应的PRB编号n PRB n PRB=10
表2
对于同步raster,在不同的频段(band)下,同步raster在band内的分布通过下表3确定。例如,对于band n77,同步raster的编号范围为9460–10079,共620个同步raster。
Figure PCTCN2018081468-appb-000002
表3
5)同步信号块的指示方法
通过PRB grid offset信息域(k SSB)中的保留值指示当前SSB不关联RMSI或者Type0-PDCCH common search space时,通过RMSI-PDCCH-Config信息域中的比特指示第二SSB(当前SSB作为第一SSB)的频域位置信息。由于RMSI-PDCCH-Config信息域包含8比特,通过指示目标同步raster和当前同步信号块对应的同步raster的偏移,可以指示256个同步raster的位置。结合PRB grid offset信息域中的不同保留值,可以指示N×265个同步raster的位置。对于频域范围(FR,frequency range)1和FR2,分别根据表4和表5,通过k SSB和RMSI-PDCCH-Config联合指示目标SSB对应的同步raster的GSCN相比当前SSB对应的同步raster的GSCN的偏移,表4指示范围包括-768…-1,1…768,表5指示范围包括-256…-1,1…256。其中,表4中k SSB=30为保留值,表5中k SSB=14为保留值。
Figure PCTCN2018081468-appb-000003
表4
Figure PCTCN2018081468-appb-000004
表5
同时,当UE收到FR1对应的k SSB=31或者FR2对应的k SSB=15时,则UE认为在GSCN范围
Figure PCTCN2018081468-appb-000005
内,不存在关联Type0-PDCCH common search space的SS/PBCH block,其中,
Figure PCTCN2018081468-appb-000006
Figure PCTCN2018081468-appb-000007
分别根据RMSI-PDCCH-Config的高位4比特和低位4比特决定。
以下结合具体实施例对本发明实施例的方案做详细描述。

步骤302:所述终端设备根据所述SSB的频域位置信息获得指示信息,所述指示信息用于指示所述SSB所关联的载波的属性,所述载波的属性包括所述载波用于授权载波 系统还是免授权载波系统。
本发明实施例中,考虑到免授权频段与授权频段会存在一些重叠的部分,为此,在免授权频段(unlicensed band)上,设置与授权频段(licensed band)不同的同步栅格(sync raster)的位置的计算方法,满足unlicensed band和license band上的同步栅格的位置不发生重叠,终端设备在检测SSB时,根据该SSB所在的同步栅格的位置,就可以确定该SSB关联的载波用于授权载波系统还是免授权载波系统。
本发明实施例中,所述SSB所关联的载波的属性包括所述载波用于授权载波系统还是免授权载波系统,换言之,所述SSB所关联的载波的属性包括所述载波上的SSB是授权载波系统发送的还是免授权载波系统发送的。
本发明实施例中,所述终端设备根据检测到的SSB所在的同步栅格的位置,获得所述指示信息。
进一步,所述终端设备检测到SSB位于第一同步栅格的位置,则确定所述SSB所关联的载波用于授权载波系统;所述终端设备检测到SSB位于第二同步栅格的位置,则确定所述SSB所关联的载波用于免授权载波系统。
这里,所述SSB所关联的载波是指,利用该SSB进行后续的信号发送和接收的载波。
这里,终端设备如何判断所检测到的SSB所在的同步栅格是属于第一同步栅格还是属于第二同步栅格,可以通过以下方式实现:
所述终端设备基于第一组公式确定所述第一同步栅格的位置;
所述终端设备基于第二组公式确定所述第二同步栅格的位置;
其中,通过所述第一组公式确定出的所述第一同步栅格的位置,以及通过所述第二组公式确定出的所述第二同步栅格的位置满足以下关系:所述第一同步栅格和所述第二同步栅格在第一频段和第二频段的重叠带宽内具有位置不同的同步栅格,所述第一频段为授权频谱,所述第二频段为免授权频谱。
如图4所示,第一频段为授权频谱,第二频段为免授权频谱,第一频段与第二频段具有重叠部分。
在一实施方式中,对于第一频段对应的第一同步栅格的位置,可以沿用上述表1所示的公式计算,具体地:
如果所述第一频段位于0至2650MHz,则基于公式N×900kHz+M×5kHz,N=1:[2944],M=-1:1,确定所述第一同步栅格的位置;
如果所述第一频段位于2400至24250MHz,则基于公式2400MHz+N×1.44MHz,N=0:[15173],确定所述第一同步栅格的位置;
如果所述第一频段位于24250至100000MHz,则基于公式[24250.08]MHz+N×[17.28]MHz,N=0:[4383],确定所述第一同步栅格的位置。
在一实施方式中,对于第二频段对应的第二同步栅格的位置,定义新的同步栅格的位置的计算方法,例如:
如果所述第一频段位于0至2650MHz,则基于公式N×900kHz+M×5kHz+O1,N=1:[2944],M=-1:1,确定所述第一同步栅格的位置;
如果所述第一频段位于2400至24250MHz,则基于公式2400MHz+N×1.44MHz+O2,N=0:[15173],确定所述第一同步栅格的位置;

其中,所述O1、所述O2、所述O3为同步栅格偏移量。
上述第一同步栅格的位置,是基于第二同步栅格的位置加入一个偏移量(offset)得 到,从而使第一同步栅格和第二同步栅格互相不重叠,如下表6所示,在一示例中,O1=450kHz,O2=0.72MHz,O3=8.64MHz。应理解,O1、O2、O3的取值不唯一。

当然,也可以针对unlicensed band单独定义新的同步栅格的计算公式,与现有同步栅格计算公式不同。如图5所示,对于第一频段,对应的第一同步栅格的位置如实线所示;对于第二频段,对应的第二同步栅格的位置如虚线所示。由于第一同步栅格和第二同步栅格通过不同的公式确定,可以保证在第一带宽和第二带宽重叠的部分内licensed和unlicensed对应的同步栅格的位置不重叠。
