Description

同步信号块位置指示方法及相关设备 技术领域
本申请涉及通信领域，尤其涉及一种同步信号块位置指示方法及相关设备。
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。为了让使用免授权频谱进行无线通信的各个通信系统在该频谱上能够友好共存，一些国家或地区规定了使用免授权频谱必须满足的法规要求。例如，在欧洲地区，通信设备遵循“先听后说”(listen-before-talk，LBT)原则，即通信设备在免授权频谱的信道上进行信号发送前，需要先进行信道侦听，只有当信道侦听结果为信道空闲时，该通信设备才能进行信号发送；如果通信设备在免授权频谱的信道上的信道侦听结果为信道忙，该通信设备不能进行信号发送。且为了保证公平性，在一次传输中，通信设备使用免授权频谱的信道进行信号传输的时长不能超过最大信道占用时间(Maximum Channel Occupation Time，MCOT)。
对于新无线(New Radio，NR)中的无线频谱，同步信号块(Synchronization Signal Block，SSB)的频域位置通过同步raster来定义，但是目前定义的同步raster，主要是根据授权频谱的需要进行设计的，因此在非授权载波的新无线(New Radio-unlicensed，NR-U)系统中，现有技术是无法对SSB的频域位置进行指示的。

参见图1，图1为本申请实施例提供的一种SSB位置指示方法的应用场景示意图。如图1所示，该应用场景中包括基站10和终端设备20。图1所示的应用场景具体可以应用在5G通信系统或后续演进的通信系统中。
上述基站10可以为下一代通信的基站，如5G的gNB或小站、微站，传输接收点(transmission reception point，TRP)等。
上述终端设备20可以是用户设备(User Equipment，UE)，即一种向用户提供语音和/或数据连通性的设备，还可以是具有无线连接功能的手持式设备或车载设备等。常见的终端设备20包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、物联网设备，可穿戴设备(例如，智能手表、智能手环、计步器)等。
基站10确定目标SSB的资源信息后，发送指示信息，该指示信息用于指示目标SSB的资源信息；终端设备20接收到指示信息后，根据指示信息确定目标SSB的资源信息，并根据目标SSB的资源信息，接收目标SSB。
参见图2，图2为本申请实施例提供的一种SSB位置指示方法的流程示意图。如图2所示，该方法包括：
S201、接收指示信息，该指示信息包括ssb-SubcarrierOffset信息域，该ssb-SubcarrierOffset信息域中的部分比特位用于指示目标SSB的资源信息。
需要说明的是，在现有技术中，ssb-SubcarrierOffset信息域中的所有比特位用于指示目标SSB的资源信息，而本申请中，ssb-SubcarrierOffset信息域中的部分比特位用于指示目标SSB的资源信息。换言之，与现有技术的区别是，在本申请中将现有技术中用于指示目标SSB位置的比特位中的部分比特位用于指示目标SSB的资源信息。比如，在现有技术中，ssb-SubcarrierOffset信息域包含5比特位，将该ssb-SubcarrierOffset信息域的5比特位用于指示目标SSB的资源信息，而在本申请中，将该ssb-SubcarrierOffset信息域的4比特位用于指示目标SSB的资源信息。
可选地，ssb-SubcarrierOffset信息域中的其他比特用于指示准共址(Quasi Co-Loacted,QCL)参数；该ssb-SubcarrierOffset信息域中的其他比特为该ssb-SubcarrierOffset信息域中除了用于指示目标SSB位置的比特位中的至少一个比特位。
比如ssb-SubcarrierOffset信息域包含5个比特位，该5个比特位中的4个用于指示目标SSB的资源信息，该ssb-SubcarrierOffset信息域中的另外1个比特位用于指示其他信息，比如QCL参数。
S202、根据ssb-SubcarrierOffset信息域中的部分比特位所指示的频域位置信息确定目标SSB的资源信息。
在一个可行的实施例中，上述指示信息还包括pdcch-ConfigSIB1信息域，根据ssb-SubcarrierOffset信息域中的部分比特位所指示的频域位置信息确定目标SSB的资源信息，包括：
根据ssb-SubcarrierOffset信息域中的部分比特位所指示的频域位置信息和pdcch-ConfigSIB1信息域中所有比特位所指示的频域位置信息确定目标SSB所在频域位置的偏移量；根据目标SSB所在频域位置的偏移量确定目标SSB的资源信息。
比如ssb-SubcarrierOffset信息域包含5个比特位，pdcch-ConfigSIB1信息域包含8个比特位，将ssb-SubcarrierOffset信息域包含5个比特位中的4个比特位和pdcch-ConfigSIB1信息域包含8个比特位用于指示目标SSB所在频域位置的偏移量。根据ssb-SubcarrierOffset信息域包含5个比特位中的4个比特位所指示的频域位置信息和pdcch-ConfigSIB1信息域包含8个比特位所指示的频域位置信息确定目标SSB所在频域位置的偏移量，再根据目标SSB所在频域位置的偏移量确定目标SSB的资源信息。
上述实施例是针对频域范围1(Frequency range1，FR1)场景来说的，对于FR2来说，ssb-SubcarrierOffset信息域本身就只包含4比特，也是通过该4比特的保留值来指示目标SBB的偏移量的。其中，FR1为0–3000MHz，FR2为3000-24250MHz。
下表1为在FR1场景下K SSB和pdcch-ConfigSIB1与目标SSB所在频域位置的偏移量之间的映射表，其中，K SSB为ssb-SubcarrierOffset信息域包含5个比特位中的4个比特位所指示的频域位置信息，pdcch-ConfigSIB1为pdcch-ConfigSIB1信息域包含8个比特位所指示的频域位置信息。
K SSB pdcch-ConfigSIB1 偏移量
12 0,1，…，255 1,2，…，256
13 0,1，…，255 -1,-2，…，-256
14 0,1，…，255 257,258，…，512
表1
下表2为在FR2场景下K SSB和pdcch-ConfigSIB1与目标SSB所在频域位置的偏移量之间的映射表。
K SSB pdcch-ConfigSIB1 偏移量
12 0,1，…，255 1,2，…，256
13 0,1，…，255 -1,-2，…，-256
14 0,1，…，255 Reserved,Reserved，…，Reserved
表2
此时，K SSB＝15时，表示与现有技术K SSB＝31时类似的含义，即UE认为在全球同步信道号(Global Synchronization Channel Number，GSCN)范围
Figure PCTCN2019116884-appb-000001
内，不存在关联Type0-PDCCH common search space的SSB，其中，
Figure PCTCN2019116884-appb-000002
和
Figure PCTCN2019116884-appb-000003
分别根据RMSI-PDCCH-Config的高位4比特和低位4比特决定。其中，
Figure PCTCN2019116884-appb-000004
为参考SSB所在raster的编号，参考SSB为包含上述指示信息的物理广播信道(Physical Broadcast Channel，PBCH)的SSB。
在一个可行的实施例中，当目标SSB所在频域位置的偏移量为目标SSB所在raster的编号与参考SSB所在raster的编号的差值，该偏移量的单位为有效raster的编号之差，有效raster为频域raster中的部分raster，根据目标SSB所在频域位置的偏移量确定目标SSB的资源信息，包括：
根据参考SSB所在raster的编号和目标SSB所在频域位置的偏移量确定目标SSB所在raster的编号；根据目标SSB所在raster的编号确定目标SSB的资源信息。
具体地，在本实施例中，偏移量是指目标SSB所在raster的编号与参考SSB所在raster的编号的差值，偏移量的单位为相邻有效raster的编号之差。在频域资源上，包含有效raster和无效raster，因此有效raster为频域上raster中的部分raster。比如偏移量的单位为3，即相邻有效raster之间包括2个无效raster，偏移量的参考SSB所在raster的编号为12，偏移量为5，则目标SSB所在raster的编号为27，如图3所示三角形表示有效raster，圆形表示无效raster。
在一个可行的实施例中，当目标SSB所在频域位置的偏移量为目标SSB所在信道带宽与参考SSB所在信道带宽之间的偏移量，该偏移量的单位为预设带宽的整数倍，所述根据目标SSB所在频域位置的偏移量确定目标SSB的资源信息，包括：
根据参考SSB所在信道带宽和目标SSB所在频域位置的偏移量确定目标SSB所在信道带宽，目标SSB所在的信道带宽为目标SSB的资源信息。
具体地，目标SSB所在的目标信道带宽的位置通过公式
Figure PCTCN2019116884-appb-000005
确定，其 中，
Figure PCTCN2019116884-appb-000006
为参考SSB所在信道带宽的位置，
Figure PCTCN2019116884-appb-000007
为目标SSB所在的目标信道带宽的位置与参考SSB所在的信道带宽的位置之间的偏移。在确定目标SSB所在的目标信道带宽的位置后，若目标信道带宽内包含一个raster，则目标信道带宽内的raster为目标SSB所在的raster；若目标信道带宽内包含多个raster，在该目标信道带宽内盲检目标SSB，进而确定目标SSB所在的raster。
将频段按照预设带宽进行划分，得到多个信道带宽，每个信道带宽值为预设带宽，每个信道带宽内包含一个或多个raster。目标SSB的偏移量是指目标SSB所在raster所位于的信道带宽与参考SSB所在raster所位于的信道带宽之间的信道带宽的个数，目标SSB所在的信道带宽是指目标SSB所在的raster所位于的信道带宽。假设每个信道带宽内包含1个raster，预设带宽为10Mhz，偏移量为4，偏移量的单位为20Mhz，在如图4所示，则目标SSB所在信道带宽与参考SSB所在信道带宽之间间隔为80Mhz，即目标SSB对应的raster所在信道带宽与参考SSB对应的raster所在信道带宽之间间隔为80Mhz，黑色三角形表示raster。
换言之，若每个信道带宽内包含一个raster，则在确定目标SSB所在的信道带宽相当于确定目标SSB所在的raster；若每个信道带宽内包含多个raster，则在确定目标SSB所在的信道带宽后，在该信道带宽内盲检目标SSB，进而确定目标SSB所在的raster。由于20MHz的信道带宽内的同步raster的个数有限，例如1-5个，终端设备在信道带宽上盲检测SSB，相比现有技术指示具体的raster的位置，并不会增加较大的复杂度。
进一步地，在确定目标SSB的资源信息后，可基于目标SSB的资源信息接收目标SSB。
可以看出，在本申请实施例的方案中，通过在NR-U中定义的PBCH中承载的信息比特，相应的重新定义指示同步信号块位置的方法，可以在NR-U系统中实现同步信号块的指示，使得基站可以指示有效的同步栅格的位置，或者有效的同步栅格所在的信道带宽的位置，可以增加指示目标同步信号块的位置的频域范围，同时减少UE检测目标同步信号块的复杂度。

具体地，在本实施例中，偏移量是指目标SSB所在raster的编号与参考SSB所在raster的编号的差值，偏移量的单位为相邻有效raster的编号之差。在频域资源上，包含有效raster和无效raster，因此有效raster为频域上raster中的部分raster。比如偏移量的单位为3，即相邻有效raster之间包括2个无效raster，偏移量的参考SSB所在raster的编号为12，偏移量为5，则目标SSB所在raster的编号为27，如图3所示三角形表示有效raster，圆形表示无效raster。
