具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
下面先对本发明中涉及的高频相关背景做一个简要说明,如下所示:
1、高频相关背景
新无线(New radio,NR)系统的研究目前主要考虑两个频段,频段FR1(Frequency range 1)和频段FR2(Frequency range 2),其中,FR1和FR2包括的频域范围如表1所示。
频段定义 对应频段范围
FR1 410MHz–7.125GHz
FR2 24.25GHz–52.6GHz
表1
随着NR系统的演进,新的频段即高频上的技术也开始进行研究。新频段包括的频域范围如表2所示,为便于描述,本申请中用FRX表示,应理解,该频段名称不应构成任何限定。
高频 对应频段范围
FRX 52.6GHz–71GHz
表2
FRX频段中包括授权频谱,也包括非授权频谱。或者说,FRX频段中包括非共享频谱,也包括共享频谱。非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。
为了让使用非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非授权频谱必须满足的法规要求。例如,通信设备遵循“先听后说(Listen Before Talk,LBT)”原则,即通信设备在非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;如果通信设备在非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。又例如,为了保证公平性,在一次传输中,通信设备使用非授权频谱的信道进行信号传输的时长不能超过一定时间长度。又例如,为了避免在非授权频谱的信道上传输的信号的功率太大,影响该信道上的其他重要信号的传输,通信设备使用非授权频谱的信道进行信号传输时需要遵循不超过最大功率谱密度的限制,等等。
FRX频段考虑的子载波间隔比FR2的子载波间隔更大,目前的候选子载波间隔包括以下几种中的至少一种:240kHz、480kHz、960kHz、1.92MHz、3.84MHz。作为示例,这些候选子载波间隔下对应的参数集(Numerology)如下表3所示。
子载波间隔 符号长度 正常CP长度 延长CP长度 时隙长度
240kHz 4.16us 0.292us 1.04us 62.5us
480kHz 2.08us 0.146us 0.52us 31.25us
960kHz 1.04us 0.073us 0.26us 15.625us
1.92MHz 0.52us 0.037us 0.13us 7.8125us
3.84MHz 0.26us 0.018us 0.065us 3.90625us
表3
2、NR同步信号块(Synchronization Signal Block,SSB)图案
NR系统中,FR1支持的同步信号块(Synchronization Signal/PBCH Block,SSB或SS/PBCH block)图案包括3种情况(Case A,B,C),FR2支持的SSB图案包括2种情况(Case D,E)。其中,一次SSB传输机会可以包括一个或多个SSB,一个SSB在时域上包括4个符号,一组SSB应在一个半帧(5ms)内完成传输。假设一个半帧内的第一个时隙的第一个符号的索引为符号0:
(1)Case A-15kHz子载波间隔:
1)SSB的第一个符号的索引包括{2,8}+14*n;
2)对于非共享频谱:
①载波频率小于或等于3GHz,n=0,1;
②FR1内载波频率大于3GHz,n=0,1,2,3;
3)对于共享频谱,n=0,1,2,3,4。
(2)Case B-30kHz子载波间隔:
1)SSB的第一个符号的索引包括{4,8,16,20}+28*n;
①载波频率小于或等于3GHz,n=0;
②FR1内载波频率大于3GHz,n=0,1。
(3)Case C-30kHz子载波间隔:
1)SSB的第一个符号的索引包括{2,8}+14*n;
2)对于非共享频谱且属于成对频谱(例如频分双工(Frequency Division Duplex,FDD)场景);
①载波频率小于或等于3GHz,n=0,1;
②FR1内载波频率大于3GHz,n=0,1,2,3;
3)对于非共享频谱且属于非成对频谱(例如时分双工(Time Division Duplex,TDD)场景);
①载波频率小于或等于2.4GHz,n=0,1;
②FR1内载波频率大于2.4GHz,n=0,1,2,3。
如图1A所示,为NR系统中在不同情况下关于FR1的部分SSB图案的一个示意图。
4)对于共享频谱,n=0,1,2,3,4,5,6,7,8,9。
(4)Case D-120kHz子载波间隔:
1)SSB的第一个符号的索引包括{4,8,16,20}+28*n;
①对于FR2内的载波频率,n=0,1,2,3,5,6,7,8,10,11,12,13,15,16,17,18。
(5)Case E-240kHz子载波间隔:
1)SSB的第一个符号的索引包括{8,12,16,20,32,36,40,44}+56*n;
①对于FR2内的载波频率,n=0,1,2,3,5,6,7,8。
如图1B所示,为NR系统中在不同情况下关于FR2的部分SSB图案的一个示意图。
3、NR系统中的SSB传输
在NR系统中,对于FR1频段,一个SSB突发集合中最多有8个SSB,最多需要3bit指示这8个SSB的索引,这3bit通过物理广播信道(Physical Broadcast Channel,PBCH)的解调参考信号(Demodulation Reference Signal,DMRS)序列隐式承载,共有8个不同的PBCH的DMRS序列,分别对应8个不同的SSB索引。对于FR2频段,由于所处频率更高,为了保障信号长距离传输其波束能量也需更为集中,相应地单波束覆盖角度将更小,继而需要采用更多的波束以保证小区的覆盖范围。目前在FR2频段最多可配置64个SSB,需要用6bit指示这64个SSB的索引,这6bit中的低3bit还是通过PBCH的DMRS序列承载的,额外的高3bit是通过PBCH的负载内容直接指示的。
SSB索引的一项主要功能是让UE获取系统时序信息,除此之外,SSB索引还有另外一项功能,即用于指示SSB之间的准共址(Quasi Co-Location,QCL)关系。信号之间的QCL关系用于描述其大尺度参数特征相似程度,如果两个信号之间是QCL的关系,则可认为这两个信号的大尺度参数相似。具体到SSB来说,在5G NR系统中不同波束承载的SSB构成一个SSB突发集合,不同SSB索引对应了突发集合内不同SSB时域位置信息的同时,也对应了特定的SSB传输波束信息。具有同样SSB索引的SSB之间可认为具有QCL关系,用户设备(User Equipment,UE)可假设基站采用了相同的波束用于传输这些SSB;不同SSB索引对应的SSB之间不认为存在QCL关系,因为它们可能来自于不同的基站传输波束,经历了不同的信道传输特征。
对于FR1,网络设备通过采用完整的比特位图指示实际传输的SSB索引,比特位图中一个比特对应一个SSB索引,若该比特取值为“1”,表示网络设备发送了该SSB,若该比特取值为“0”,表示网络设备未发送该SSB。
对于FR2,当网络设备通过SIB1指示传输的SSB索引,例如通过SIB1中的SSB在突发集合中的位置指示(例如ssb-PositionsInBurst)提供对应的配置信息时,为了节省信令开销,将SSB的传输候选位置进行分组,并基于分组比特位图指示有实际SSB传输的分组,且基于组内比特位图指示每一个有实际SSB传输的分组内实际传输的SSB的位置,其中,每组内的实际传输的SSB的位置相同。具体地,将64个SSB候选位置划分为8组,每组中包括8个SSB,则共需要使用8个比特指示分组,另外8个比特位图指示每组内有SSB发送的位置,因此该方法总共需要16个指示比特。作为示例,假设分组比特位图,例如群组指示(例如groupPresence)为“11000000”,则表示第0组SSB(SSB索引0到7)和第1组SSB(SSB索引8到15)中的SSB根据组内比特位图的指示进行SSB传输。假设组内比特位图,例如组内指示(inOneGroup)指示“11001100”,则进一步表示第0组SSB中的第0、1、4、5个SSB传输候选位置和第1组SSB中的第0、1、4、5个SSB传输候选位置上有SSB传输。也就是说,在该示例中,网络设备传输的SSB索引为SSB0、SSB1、SSB4、SSB5、SSB8、SSB9、SSB12、SSB13。当网络设备通过服务小区的配置信息指示传输的SSB,例如通过服务小区公共配置指示(例如ServingCellConfigCommon)中的ssb-PositionsInBurst提供对应的配置信息时,采用完整的比特位图即使用64个比特指示传输的SSB索引。终端设备应期望ServingCellConfigCommon中的ssb-PositionsInBurst提供的配置信息和SIB1中的ssb-PositionsInBurst提供的配置信息相同。
4、NR-U系统中的SSB传输
在NR-U系统中,终端设备的初始接入过程可以通过检测发现信号传输机会(Discovery Burst)窗口中的SSB突发集合来完成。发现信号传输机会窗口是周期出现的,发现信号传输机会窗口中可以包括多个用于SSB传输的候选位置。网络设备在发现信号传输机会窗口内发送SSB时,可以进行多次LBT尝试,并且在LBT成功后可以通过该多个候选位置中的至少一个候选位置进行SSB传输。基站在不同的发现信号传输机会窗口内,可以根据LBT结果从该发现信号传输机会窗口内的SSB候选位置中,选择获得信道使用权的候选位置进行SSB传输。
在非授权频谱上的载波上,发现信号传输机会窗口的长度可以是网络设备配置的。例如,对于一个服务小区,终端设备可以通过网络设备的指示信息,例如DiscoveryBurst-WindowLength-r16来确定发现信号传输机会窗口的长度。可选地,指示信息指示的发现信号传输机会窗口的长度可以为0.5ms、1ms、2ms、3ms、4ms或5ms。
如果终端设备未被网络设备配置发现信号传输机会窗口的长度。例如终端设备未被提供DiscoveryBurst-WindowLength-r16指示信息,那么终端设备可以假设发现信号传输机会窗口的长度为一个半帧即5ms。
一个时隙中可以包括2个候选SSB位置,在候选SSB位置上发送的SSB的索引可以认为是候选SSB索引。在一个半帧(5ms)内可以包括的候选SSB位置的最大个数和子载波间隔相关。如果SSB的子载波间隔是15kHz,那么候选SSB位置的最大个数为10个,在该半帧内候选SSB位置上发送的候选SSB索引在时域上分别为从0到9;如果SSB的子载波间隔是30kHz,那么候选SSB位置的最大个数为20个,在该半帧内候选SSB位置上发送的候选SSB索引在时域上分别为从0到19。图1C给出了一个半帧内候选SSB位置的示意图。可选地,该半帧可以为无线帧中的前半帧(前5ms)或后半帧(后5ms)。
终端设备可以根据准共址(Quasi co-location,QCL)假设指示信息Q来确定具有相同QCL假设的候选SSB位置,或者说,终端设备可以根据Q来确定SSB索引。其中,Q可以是网络设备指示的或预设的。Q用于指示一个发现信号传输机会窗口内网络设备可以发送的最大的SSB个数,或者说,Q用于确定SSB索引。Q的取值可以为1、2、4或8。其中,SSB索引=(候选SSB索引mod Q),或者,SSB索引=(PBCH的DMRS序列索引mod Q)。例如,如果Q取值为4,在候选SSB位置10上发送的SSB的候选SSB索引为10,因此可以认为在该候选SSB位置10上发送的SSB的SSB索引为(10 mod 4)=2。
终端设备可以通过网络设备的指示信息例如ssb-PositionsInBurst来确定实际发送的SSB。该指示信息对应一个bitmap,其中,该bitmap中的第1个比特对应SSB索引0,该bitmap中的第2个比特对应SSB索引1,等等,以此类推。作为示例,如果该比特为0,用于指示该比特对应的SSB未被传输,如果该比特为1,用于指示该比特对应的SSB被传输。可选地,该指示信息例如ssb-PositionsInBurst对应的bitmap的长度为8。可选地,终端设备可以假设该bitmap中大于Q的比特位置为0。
终端设备应期望ServingCellConfigCommon中的ssb-PositionsInBurst提供的配置信息和SIB1中的ssb-PositionsInBurst提供的配置信息相同。
例如,假设一个服务小区上ssb-PositionsInBurst对应的bitmap为[10100000],Q取值为4,那么说明该服务小区上发送的SSB索引为SSB 0和SSB 2。如果SSB的子载波间隔是30kHz,发现信号传输机会窗口长度为5ms,如图1A所示,那么可以用于SSB传输的候选SSB位置包括候选SSB位置0、2、 4、6、8、10、12、14、16、18。在一个示例中,如果网络设备在候选SSB位置6处LBT成功,那么网络设备实际用于SSB传输的候选SSB位置包括候选SSB位置6和8,或者说,网络设备发送的候选SSB索引为SSB6和SSB8。在该发现信号传输机会窗口中,如果网络设备获得的信道占用中还包括候选SSB位置10、12、14、16、18,那么该候选SSB位置10、12、14、16、18不用于SSB发送。
当新无线(New radio,NR)系统布网在高频中,由于FRX频段中包括非共享频谱,也包括共享频谱,共享频谱上的同步信号块(Synchronization Signal Block,SSB)传输可能需要多个候选位置,以使网络设备可以在先听后说(Listen Before Talk,LBT)成功后通过该多个候选位置中的至少一个候选位置进行SSB传输。由于高频中包括64个SSB,或者甚至可能引入更多的SSB个数例如128个SSB,在该场景下,如何定义SSB的QCL关系是需要讨论的问题。

可选的,N为大于20的整数。
可选的,N的取值为64或128。示例性的,N的取值可以为64或128或者其他的取值。
可以理解的是,因为所述N个候选SSB位置中的每个候选SSB位置对应一个候选SSB索引,那么,当N的取值为64时,SSB突发集合包括64个候选SSB位置,64个候选SSB位置对应64个候选SSB索引;当N的取值为128时,SSB突发集合包括128个候选SSB位置,128个候选SSB位置对应128个候选SSB索引。
可选的,所述SSB突发集合对应的子载波间隔为120kHz,N的取值为128,和/或,所述SSB突发集合对应的传输窗口长度为10ms。即对于120kHz子载波间隔,SSB突发集合中包括的候选SSB个数可以扩展为128个,和/或,SSB突发集合对应的传输窗口长度可以扩展为10ms。
可选地,重用PBCH中的信息域来指示新增的SSB索引。例如,固定SSB突发集合传输的起始位置为前半帧,重用PBCH中的半帧指示来指示新增的SSB索引。

可以理解的是,M个第一候选SSB索引具有相同的QCL关系,可以认为是M个第一候选SSB索引指示的SSB具有相同的QCL关系,或者,也可以认为是M个第一候选SSB索引对应的SSB位置具有相同的QCL关系。
(1)其中,所述第一指示信息指示Q值,所述终端设备根据第一指示信息确定所述N个候选SSB索引的QCL关系,包括:

示例性的,当Q的取值为8时,第一SSB索引还可以根据PBCH的DMRS序列索引确定。
可以理解的是,和NR-U系统类似地,在高频系统中,也可以引入准共址(Quasi co-location,QCL)第一指示信息Q来确定具有相同QCL的候选SSB位置。Q可以用于指示最多可传输的SSB个数,或者,终端设备可以根据Q来确定SSB索引。

其中,r=0,1,…,M-1;k=0,1,…,ceil(N/M)-1,ceil()表示上取整。
示例性的,当N的取值为64时,SSB突发集合中包括的可传输的SSB索引为SSB(kM),其中,k 取值为0,1,…,64/M-1。M为一个SSB索引对应的候选SSB索引(或位置)的个数。可选的,一个SSB索引对应的连续M个候选SSB索引。64/M为可传输的SSB索引的最大个数。
可选地,M的取值可以为1、2、4、8。
可选的,所述第一SSB索引对应所述N个候选SSB索引中连续的M个第一候选SSB索引。
可选的,所述第一指示信息指示M值,其中,
如果M的取值为8,所述SSB突发集合中可传输的第一SSB索引的个数小于或等于8;
如果M的取值为4,所述SSB突发集合中可传输的第一SSB索引的个数大于8,且,小于或等于16;
如果M的取值为2,所述SSB突发集合中可传输的第一SSB索引的个数大于16,且,小于或等于32;
如果M的取值为1,所述SSB突发集合中可传输的第一SSB索引的个数大于32,且,小于或等于64。
可选的,所述第一指示信息指示M值,其中,
如果M的取值为4,所述SSB突发集合中可传输的第一SSB索引的个数能被2整除;
如果M的取值为2,所述SSB突发集合中可传输的第一SSB索引的个数能被4整除;
如果M的取值为1,所述SSB突发集合中可传输的第一SSB索引的个数能被8整除。
示例性的,如果M=8,网络设备发送的SSB波束的个数小于或等于8。如果M=4,网络设备发送的SSB波束的个数大于8且小于或等于16。如果M=4,网络设备可以发送的SSB的个数能被(8/M=2)整除,例如为2、4、6、8、10、12、14、16中的一种。如果M=2,网络设备发送的SSB波束的个数大于16且小于或等于32。如果M=2,网络设备可以发送的SSB的个数能被(8/M=4)整除,例如为4、8、12、16、20、24、28、32中的一种。如果M=1,网络设备发送的SSB波束的个数大于32且小于或等于64。

可选的,如果M的取值为1,则所述SSB突发集合中不包括QCL关系相同的候选SSB索引。即如果M=1,则说明SSB突发集合中不包括QCL关系相同的两个SSB。
可以理解的是,M用于确定一个组内的SSB的QCL关系,或者M用于指示一个组内的一个SSB索引对应候选SSB位置的个数,其中,不同的组遵循相同的QCL准则。
304、所述网络设备向所述终端设备发送第二指示信息,所述第二指示信息用于指示所述SSB突发集合中传输的SSB索引,所述第二指示信息包括N个比特,或者,所述第二指示信息包括(L+C)个比特,其中,LC=N,L、C均为正整数。

所述第二指示信息包括(L+C)个比特,所述N个候选SSB索引被划分为L组,其中每组中包括C个候选SSB索引,所述L个比特与所述L组一一对应,所述C个比特与每组中的所述C个候选SSB索引一一对应。
可选的,所述第一指示信息指示Q值,Q为大于或等于1,且,小于或等于N的整数,其中,
如果所述第二指示信息包括N个比特,所述N个比特中的前Q个比特为有效比特;或者,
如果所述第二指示信息包括(L+C)个比特,所述(L+C)个比特中的有效比特根据以下至少一种确定:
如果Q小于或等于C,所述C个比特中的前Q个比特为有效比特;
如果Q大于C,所述C个比特为有效比特,所述L个比特中的前ceil(Q/C)个比特为有效比特,ceil()表示上取整。
示例性的,网络设备选取不同组中相同的候选SSB位置来进行SSB的传输。可选地,分组比特位图例如groupPresence中的前(Q/8)个比特为有效比特。例如,如果Q=8,分组比特位图中的第1个比特为有效比特;如果Q=16,分组比特位图中的前2个比特为有效比特;如果Q=32,分组比特位图中的 前4个比特为有效比特;如果Q=64,分组比特位图中的8个比特均为有效比特。
可选的,所述第一指示信息指示Q值,Q为大于或等于1,且,小于或等于N的整数,所述第二指示信息包括(L+C)个比特,如果Q小于或等于(L+C),所述(L+C)个比特中的前Q个比特为有效比特,其中,所述(L+C)个比特中所述C个比特位于所述L个比特之前,或者,所述(L+C)个比特中所述L个比特位于所述C个比特之前。
可选的,所述第一指示信息指示Q值,Q为大于或等于1且小于或等于N的整数,其中,
如果Q的取值为8,所述SSB突发集合中可传输的第一SSB索引的个数小于或等于8;
如果Q的取值为16,所述SSB突发集合中可传输的第一SSB索引的个数大于8,且,小于或等于16;
如果Q的取值为32,所述SSB突发集合中可传输的第一SSB索引的个数大于16,且,小于或等于32;
如果Q的取值为64,所述SSB突发集合中可传输的第一SSB索引的个数大于32,且,小于或等于64。
可选的,所述第一指示信息指示Q值,Q为大于或等于1,且,小于或等于N的整数,其中,
如果Q的取值为16,所述SSB突发集合中可传输的第一SSB索引的个数能被2整除;
如果Q的取值为32,所述SSB突发集合中可传输的第一SSB索引的个数能被4整除;
如果Q的取值为64,所述SSB突发集合中可传输的第一SSB索引的个数能被8整除。
示例性的,如果Q=8,网络设备发送的SSB波束的个数小于或等于8。如果Q=16,网络设备发送的SSB波束的个数大于8且小于或等于16。可选地,该情况下,网络设备可以发送的SSB的个数能被2整除,例如为10、12、14、16中的一种。如果Q=32,网络设备发送的SSB波束的个数大于16且小于或等于32。可选地,该情况下,网络设备可以发送的SSB的个数能被4整除,例如为20、24、28、32中的一种。如果Q=64,网络设备发送的SSB波束的个数大于32且小于或等于64。
例如,假设Q取值为16,则SSB0和SSB8的QCL关系如图3C所示,其中,在图3C所示中,SSB0对应的候选SSB索引包括SSB0,SSB16,SSB32,SSB48,即SSB0可以通过SSB0,SSB16,SSB32,SSB48对应的候选SSB位置传输;SSB8对应的候选SSB索引包括SSB8,SSB24,SSB40,SSB56,即表示SSB8可以通过SSB8,SSB24,SSB40,SSB56对应的候选SSB位置传输。其他的SSB索引可以类似得到。在该情况下,SSB突发集合中包括的可传输的第一SSB索引为SSB0~SSB15。
可选的,如果Q的取值为64,则所述SSB突发集合中不包括QCL关系相同的候选SSB索引。即如果Q=64,则说明SSB突发集合中不包括QCL关系相同的两个SSB。
可选的,所述第二指示信息是网络设备通过系统消息SIB1发送的,或者,所述第二指示信息是所述网络设备通过高层配置参数发送的。
然而,当网络设备通过SIB1指示传输的SSB索引时,将64个SSB候选位置划分为8组,每组中包括8个SSB,共使用16个比特来指示传输的SSB索引。因此在现有的SSB传输指示方式中,无法直接指示该SSB突发集合中任意组合传输的SSB索引。例如,如果网络设备想传输SSB0和SSB10,则无法通过该方式指示传输的SSB索引。
在一些可选的实施例中,当网络设备通过SIB1指示传输的SSB索引,例如通过SIB1中的ssb-PositionsInBurst提供对应的配置信息时,可以采用完整的比特位图即使用64个比特指示传输的SSB索引。
在一些可选的实施例中,当网络设备在选定可传输的SSB索引时,需要满足现有的SSB传输指示方式的指示规则。
需要说明的是,在本发明实施例中,步骤301-步骤304的时序不做限定。
在本发明实施例中,终端设备确定SSB突发集合,所述SSB突发集合中包括N个候选SSB位置,所述N个候选SSB位置中的每个候选SSB位置对应一个候选SSB索引,N为大于20的整数;所述终端设备根据第一指示信息确定N个候选SSB索引的准共址QCL关系。即由于高频中包括64个SSB,或者甚至可能引入更多的SSB个数例如128个SSB,在该场景下,可以更准确的定义SSB的QCL关系。在高频中引入QCL关系指示后,可以使高频的SSB突发集合中,对应一个波束的SSB或SSB索引可以通过多个候选SSB位置中的至少一个进行发送,从而使网络中可以有更多的SSB传输机会,提高终端设备初始接入和测量的性能。
