为了方便理解,以下对本申请实施例涉及的一些内容进行说明:
无线设备(终端)通过小区搜索过程,从基站小区提供同步信号和广播信号/信道和基站进行时频域同步,并获取基站部署的小区的时频资源在频域、时域的位置,和物理小区ID。对于5G NR(New Radio,新无线)而言,具体的:
终端先检测NR-PSS(Primary Synchronization Signal,主同步信号),获得物理小区ID的一部分,即获得正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号定时,进行时间同步和频率同步;再检测SSS(Secondary Synchronization Signal,辅同步信号),获得物理小区ID的另一部分,即得到完整的物理小区ID,即物理小区标识(Physical Cell Identifier,PCI)。其中,
然后终端检测物理广播信道(Physical Boardcast Signal,PBCH)和解调PBCH的解调参考信号(De-modulation Reference Signal,DMRS),得到系统帧编号(System Frame Number,SFN)和同步信号块或同步信号/物理广播信道信号块(Synchronization Signal Block,SSB)索引,进一步得到无线帧(subframe)定时。
运营商往往同时运营多个制式的网络,例如,5G部署后,会存在2G、3G、4G、5G同时运营的场景。随着移动宽带网络业务流量需求的不断增加,运营商2G/3G网络重耕到4G,再从4G重耕到5G。传统运营商多制式网络中每个制式都需要固定占用一定的频谱资源,由于每个制式都独占频谱,如果不同制式间的频谱不能错峰共享使用,会导致了频谱资源的严重浪费。而4G和5G频谱共享技术能够实现在同一频段按需、动态地为4G或5G分配频谱资源。
如图2所示,频谱共享可以通过静态和动态两种方式实现:
静态频谱共享,指在同一频段内为不同制式的网络(比如4G和5G)分别提供专用的载波。这种方式“简单透明”,但频谱利用率较低;
动态频谱共享,指在同一频段内为不同制式的网络动态、灵活的分配频谱资源。这种方式可提升频谱效率,且利于不同制式的网络(比如4G和5G)之间平滑演进。
无论是静态还是动态频谱共享,4G和5G都分别提供各自同步信号和PBCH,提供相似的功能,如时频域同步,系统帧编号,子帧索引等。
相关技术中,同步信号,广播信道(携带主信息块MIB)和系统信息的结构(格式/类型)包括主/辅同步信号,广播信道和系统信息的时频资源组成结构,如所占用的时频资源大小,在时频资源中的位置等基本都是固定的,因此无法适用于多种通信场景。另外,4G,5G系统不能支持低能力终端,如设备的接收带宽小于同步信号和/或广播信道的带宽;或不能够灵活,有效地支持多种终端类型,多种部署场景,用例等。
4G和5G即使共站共享频谱,4G和5G的同步信号,广播信道也是相互独立的。同步信号主要用来进行时频同步,而共站共享频谱的不同无线网络制式发送独立的同步信号实现相同/重复的功能会增加基站功耗,增加频谱资源的开销。
因此,新的通信系统(例如,6G)需要设计一种灵活的同步信号,广播信道以及系统信息结构,满足万物连接(例如,多种不同能力类型的设备,不同的服务用例),泛在连接(例如,TN,NTN等)等需求。下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的传输方法、终端、网络侧设备及介质进行详细地说明。

可选的实施方式中,候选目标信息也可以是第一候选目标信息和第二候选目标信息,同样可以基于不同场景从第一候选目标信息和第二候选目标信息中选择适合的候选目标信息作为下述第一目标信息,从而提高同步信号,广播信道或系统信息对多种场景通信的适应性。
可选的,第二候选目标信息为目标对象的预设候选目标信息。
本申请实施例中,第二候选目标信息的配置是以目标对象为参考的,可以理解为每个目标对象有对应的候选目标信息。不同的目标对象之间的候选目标信息可以相同也可以不同,同一目标对象也可以有多个候选目标信息。即第二候选目标信息与目标对象之间可以是一对一,也可以是一对多,也可以是多对一的关系。

上述终端类型可以是预设的,或者协议约定的;类似的,上述终端能力也可以是预设的,或者协议约定的。
以6G为例,6G无线通信系统将灵活支持不同的“功能(Feature)”。
相关技术中,同步信号和广播信道组成SSB,可以理解的是,本申请实施例中,同步信号和广播信道可以是SSB结构,但不局限于这种结构,例如,同步信号和广播信道两者之间独立发送。且,本申请实施例不局限于某种通信系统,可以是6G无线通信系统,可以用于5G某些特殊场景,比如IoT场景,也可以用于未来任何无线通信系统。
本申请实施例中的SSB术语,也可以表述为其他任何表示传输同步信号,物理广播信道的信号块,比如也可以叫6G-SSB;本申请实施例中的MIB术语,也可以表述为其他任何表示主系统信息模块,比如也可以叫6G-MIB。换而言之,本申请实施例中的技术术语不限制于现有通信系统,可以对应其他或未来通信系统中具有相同功能的参数。
本申请实施例中,同步信号、广播信道或系统消息的“结构(structure)”,可以和“格式(format)”,“类型(type)”等词语互换。
可选的,所述第一候选目标信息包括如下参数中的至少一项:

或者,所述第一候选目标信息的PBCH的时域资源大于或者等于3个正交频分复用OFDM符号;
或者,所述第一候选目标信息的PBCH携带的信息比特数小于或等于第一预设阈值。
本申请实施例中,第一候选目标信息结构可以考虑如下一种或者多种因素:
(1)第一候选目标信息的带宽设置可以从终端角度考虑,也可以从网络侧角度考虑,设置最小带宽,例如,使用小于20物理资源块(physical resource block,PRB)的频域宽度作为同步信号(PSS/SSS)或PBCH的带宽,比如6PRB;
考虑到未来网络以4G,5G,6G共存为主,4G(IoT除外)最小带宽为6PRB,可以使用72长度的PSS,考虑到5GPSS长度为127,6G可以尽量使用6PRB的PSS/SSS设计。
本申请实施例中,PRB与资源块(resource block,RB)的描述可以互换。
(2)相对于5G使用增强的PBCH设计;
比如更窄的SSB beam关联更窄的CSI-RS beam,通过CSI-RS训练beam下行接收,提高PBCH的接收性能。
受制于频域带宽,时域使用更多的PBCH重复,为保证PBCH的覆盖,时域上,使用大于或等于3个OFDM符号传输PBCH或重复传输PBCH,例如,在SSB burst内做SSB重复(可以是SSB方向也重复)或者仅仅做PBCH重复;PBCH携带的总信息比特数(不包括循环冗余校验码CRC)小于32bit,或者,PBCH携带的总信息比特数(包括CRC)小于56bit。
(3)多个目标对象公共(可以理解为通用)的第一候选目标信息可以不用于独立的
IoT无线电接入技术(Radio Access Technology,RAT),但是可以与IoT RAT所用的SSB结构满足如下一种或者多种条件:
使用相同的候选目标信息结构,但是在IoT候选目标信息跟6G候选目标信息相比是在频域资源上按比例缩短,或在时域资源上按比例延长。或者,也可以是IoT候选目标信息跟6G候选目标信息相比是在频域资源上按比例延长,或在时域资源上按比例缩短。
IoT RAT可以理解为预设的目标对象,IoT RAT对应的候选目标信息可以理解为第二候选目标信息。
本申请实施例中,第二候选目标信息结构可以具有如下参数中的至少一项:
(1)PSS,SSS,PBCH和解调PBCH的参考信号RS占据的时域资源大小,频域资源大小,传输周期,波束方向和数目;

上述第一时间包括以下至少一项:时隙(slot),子帧(subframe),系统帧(对应SFN),超帧(对应HyperSFN),传输周期
相同波束的PSS/SSS/PBCH位于同一个时隙内;不同波束的PSS/SSS/PBCH可以位于同一个时隙内也可以位于不同的时隙内
相同波束的PSS,SSS,PBCH在时域上可以占据连续的符号,也可以是不连续的符号;比如:PSS,SSS,PBCH三者占用的是连续的符号;或者PSS,SSS,PBCH三者占用的符号两两之间都是不连续的;或者PSS,SSS,PBCH三者之间,有两者占用的符号是连续的,和另外一者占用的符号是不连续的(如:PSS和SSS是连续的符号,而PBCH占用的符号和PSS/SSS占用的符号是不连续的)。

可选的,相同波束的所述第一目标信息位于同一时隙或不同时隙;
或者,相同波束的所述第一目标信息占用连续的时域资源或不连续的时域资源;
或者,相同波束的所述第一目标信息占用连续的频域资源或不连续的频域资源。
(3)PSS,SSS,PBCH的调制方式

(4)PSS,SSS,解调PBCH的参考信号RS使用的序列
(5)PBCH的编码方式,携带的内容和内容大小(即信息量,负载,bit总数目)。
上述属于同一结构的同步信号和广播信道中,即PSS,SSS,PBCH三者之间的参数也可以不同,比如PSS/SSS和PBCH使用的时域频域资源大小,循环前缀长度,子载波间隔(SCS),传输周期,传输功率等可以不同。
示例性的,第二候选目标信息结构如图4所示。
其中第二候选目标信息结构1(SS/PBCH Structure/format/Type 1)以表1示例,用于PSS、SSS、PBCH和用于PBCH的DM-RS的资源(对应图4的结构1),时域上4个OFDM符号,编号从0~3;假设Y=20,频域上240个子载波,编号从0~239。

表3
此外,表4每个工作频段适用的SS栅格条目。
表4
可以理解的是图4中的X和Y可取其他值,例如X=6。
可选的,所述第一目标信息基于如下至少一项确定:
网络系统的带宽;
网络系统的频域范围;
同步栅格;
频谱的类型;
频谱的部署模式;
终端的能力。
本申请实施例中不同的候选目标信息可以理解为不同结构(structure)的目标信息,网络部署或终端接入部署了的网络(例如,6G)时,使用哪个结构的候选目标信息,取决于如下至少一项:
(1)与网络(例如6G)band/frequency range(FR)相关,不同的band/FR可以使用不同的结构
在一些实施例中,每个band/FR可以关联多种候选目标信息结构。
比如,低频band上,因为频谱资源受限,候选目标信息在频域上所占的RB小于20个RB,PSS/SSS/PBCH时分复用,1个波束可以满足覆盖要求(如图4中的结构2);高频band上,频域资源充裕,候选目标信息在频域上所占的RB不小于20个RB,且需要多个波束满足覆盖要求,PSS/SSS和PBCH频分复用,可以在1个时隙中发送>=2个不同的波束,提高使用不同波束传输SSB的效率(如图4中的结构3)。
又比如,在某一个band上需要支持多种feature,比如需要支持一些IoT用例,该用例
中的设备能力(接收带宽,处理能力等)非常低,移动速率低,通常部署在室内,因此覆盖比较容易满足;还需要支持一些eMBB的用例,该用例中的设备能力(接收带宽,处理能力等)比较高,移动速率高,对覆盖和业务的连续性要求高。则对IoT用例,其候选目标信息在频谱,时域上使用的资源和候选目标信息的传输周期,PBCH携带内容的大小都可以小于eMBB用例的候选目标信息。
(2)和sync.Raster(Synchronization raster,同步栅格)相关,在不同的sync.raster可以使用不同的结构。
(3)和频谱类型相关,例如频谱是否是授权频谱相关,授权频谱和非授权频谱可以使用不同的结构。
比如:相对于授权频谱上,非授权频谱上的候选目标信息需要有更多的传输机会,抢占信道。因此,相比于授权频谱,非授权频谱上,相同波束的一个候选目标信息在时域上有多个不同的位置,根据成功抢占信道的位置确定该候选目标信息在时域上的位置;而授权频谱的相同波束的一个候选目标信息在时域上的位置是固定的。
(4)和频谱的部署模式相关,比如时分双工(Time-Division Duplexing,TDD),频分双工(Frequency Division Duplex,FDD),全双工(full duplex,FD)可以使用不同的结构。
比如:FDD频谱资源受限,候选目标信息在频域上所占的RB小于20个RB,PSS/SSS/PBCH时分复用,1个波束可以满足覆盖要求(如图4中的结构2);TDD频谱资源充裕,候选目标信息在频域上所占的RB不小于20个RB,且需要多个波束满足覆盖要求,PSS/SSS和PBCH频分复用,可以在1个时隙中发送>=2个不同的波束,提高使用不同波束传输候选目标信息的效率(如图4中的结构3);
又比如,在FD模式下,基站在某些时间单元如符号/时隙/子帧需要同时发送下行和接收上行,简单起见,称这些时间单元为FD(full duplex)时隙;基站在另外一些时间单元上不需要同时发送下行和接收上行,即只发送下行或只接收上行,简单起见,称这些时间单元为HD(half duplex,半双工)时隙。Full duplex包括如下至少两种模式:1)FD模式1:基站需要在同一个时域和频域资源发送候选目标信息并接收上行信号(资源不完全重叠的全双工,包括完全重叠和部分重叠);FD模式2:基站需要在同一个时域,但是不同的频域资源发送候选目标信息并接收上行信号(资源完全不重叠的全双工,即子带全双工(subband full duplex)。为了减小基站下行候选目标信息发送对上行接收的自干扰,在HD时隙里发送的候选目标信息的发送功率可以大于在FD时隙里发送候选目标信息的发送功率;在HD时隙里发送的候选目标信息的波束数目大于在FD时隙里发送候选目标信息的波束数目,或在HD时隙里发送的候选目标信息的波束方向和在FD时隙里发送候选目标信息的波束方向不同。又比如:对于FD模式1,上行传输和下行接收的频域资源不完全重叠,即频域上不需要预留隔离资源,候选目标信息可以使用如图4结构3或1;对于FD模式2,上行传输和下行接收的频域资源完全不重叠,即频域上需要预留隔离资源,候选
目标信息可以使用如图4结构2。
(5)根据UE能力,决定检测的候选目标信息结构
比如:协议定义了两个PSS/SSS/PBCH structure,简称SSB structure#1和SSB structure#2,SSB Structure#1在频域上使用了X1个RB,SSB Structure#2在频域上使用了X2个RB,其中X1<X2
终端侧:UE#1的接收带宽能力是X3个RB,X1<=X3<X2,UE#2的接收带宽能力是X4个RB,X4>=X2,则UE#1只检测SSB structure#1;而UE#2可以只检测SSB structure#2,也可以SSB structure#1和SSB structure#2都检测,也可以只检测SSB structure#1或UE#2可以先检测其中的一个SSB structure,若没有检测成功,则尝试检测另外一个SSB structure。
网络侧:网络在一个小区内可能只发送一个SSB structure,也可能发送两个SSB structure。
(6)由UE在支持的频段上在同步栅格上搜索或检测,比如:协议只定义两个PSS/SSS/PBCH structure,UE在每个Sync.raster上最多检测两个PSS/SSS/PBCH structure,提高网络部署的灵活性,且UE侧的盲检测复杂度可接受。
终端在连接态需要进行小区切换时,从当前小区切换到目标小区。目标小区的确定可以由网络决定或终端搜索/检测决定。
可选地,所述终端在支持的频段上在同步栅格上搜索或检测所述网络侧设备发送的第一目标信息。
可以理解的是,本申请实施例中上述候选目标信息替换为SSB也同样适用。

可选的,“第一级”信息根据协议预定义的工作频段与时频域资源位置的绑定关系,来进行映射,利于UE进行初始接入时的搜索。SS Info Pattern定义了一组同步信息在子帧中
可能的时域位置,而全局同步信道号(Global Synchronization Channel Number,GSCN)则定义了一个SSB在当前频段中可能频域位置。NR利用这种预定义的关系有效减少了搜索复杂度。注意到,在6G中由于工作频段待定,表5为“第一级”信息的映射,因此表5中n1~n_x的划分可能与NR中的有所不同,相应的SS Info Pattern与GSCN的定义与取值可能也与NR中的不同。
表5
与NR显著不同的是,“第二级”信息比如可以用来补充指示“feature specific”的系统信息,以及辅助同步和测量等功能。为了减少检测次数,把“第二级”信息的资源位置与“第一级”信息相关联,即在某个6G频段内,固定某个“Feature Type”类型对应的“第二级”信息的资源位置与当前频段内检测到的“第一级”信息资源位置之间的偏移值(Offset),从而可以避免进一步检测而得到“第二级”信息。其中“Feature Type”的获取可以由UE根据自己的设备类型/工作模式/协议预配置确定,也可以由“第一级”信息内携带的信息进行指示偏移值(Offset)。
可选的,第二级SSB的配置至少部分可以通过查找表的方式确定,包括单不限于如下至少一种信息:
·SSB针对的目标功能类型;
·SSB相对于第一参考信号的一个时间offset
·SSB相对于第一参考信号的频域offset。
比如,表格6所呈现的是一种可能的“第二级”信息时频域资源位置确定方式。在某个特定的工作频段内,针对每一种“Feature Type”,都用查询表(lookup table)唯一的规定了“第二级”信息相于“第一级”信息的时频域资源位置的偏移量。此外,可选的方法还包括“第二级”信息相于“第一级”信息的时频资源位置的偏移量是根据工作频段编号n_x与“Feature Type”所计算得到的值。或者“第二级”信息的时频资源位置的是根据工作频段编号n_x,“Feature Type”以及“第一级”信息的时频域资源位置所计算得到的值。
表6
为了降低终端接收下行同步广播信号的复杂度,需要引入各级SSB之间在各个层面的关联关系。
在一些实施例中,不同级别的同步或广播信号模块之间的关联,关联的同步或广播信号模块之间可以认为在如下一个或者多个方面是准共址(quasi co-located):
多普勒频移;
多普勒扩展;
平均延迟;
延迟扩展;
空间RX(空间波束或接收天线)参数。
上述“最小公共”或“第一级”同步信号和/或广播信息提供小区的公共信息,多个feature共享该公共信息,包括如下至少一项:
时域和频域同步,小区物理ID,符号定时,子帧/系统帧/超帧号;
波束QCL(Quasi Co-Location,准共址)信息:比如第一级的同步信号和/或广播信息提供宽/粗波束的QCL信息。通过宽/粗波束,减少终端检测到小区的时延。
第二级同步信号和/或广播信息的传输信息,如第二级同步信号和/或广播信息的时频域资源位置,子载波间隔(SCS),解调参考信号的配置;
接入控制信息,比如该小区允许或不允许哪个/些feature接入该小区
上述“功能特有”或“第二级”同步信号和/或广播信息提供6G小区所支持的多个feature的feature特有的信息,该特有信息为某个feature独享,包括如下至少一项:
其他的时间信息:超帧号,第一级和/或第二级同步信号和/或广播信息传输周期
其他的频域信息:系统带宽
其他的波束信息:比如第二级的同步信号和/或广播信息提供窄/细粗波束的QCL信息其他系统信息的传输信息
广播信息可以是PBCH,系统信息块(System Information Block,SIB)等系统信息。
比如如果是SIB的情况下,6G可以构造SS/PBCH/SIB block,避免5G中对CORESET0
(control resource set 0,控制资源集0)通过MIB的设计.
其他接入控制信息,
比如:第二级的同步信号和/或广播信息是为低能力终端提供的,低能力的终端可以进一步分为只支持1Rx,支持2Rx,只支持半双工的,只支持小带宽的低能力终端。在其他接入控制信息里,针对多种低能力终端可以进一步指示允许或不允许哪个/些低能力终端的接入该小区,如不允许1Rx/半双工/A-IoT的终端接入该小区。

第一信息里波束信息,包括波束方向所覆盖的范围可以比第二信息里的波束方向所覆盖的范围大,即第一信息里的波束是粗/宽波束,第二信息里的波束是细/窄波束。此外,第一信息里的波束和第二信息里的波束是共址QCL的。
本申请实施例中,可以是第一信息中时域信息,频域信息,波束信息,传输信息,接入控制信息中的至少一项与第二信息中的对应信息存在预设偏移值。

示例性的,6G无线通信系统并期待与现有的4G/5G无线接入网RAT高效共存。当6G系统和其他无线系统共享频谱时:

或者,其他无线系统(未来通信系统)的同步信号共享6G无线系统的同步信号,其他无线系统的广播信息独立
比如:6G和5G系统共站址共享频谱,6G使用5G的SSB,但是6G有独立的系统信息
终端通过检测5G的PSS/SSS和/或SSB,进行时间频率同步,获知系统子帧号,系统
帧号;
终端根据上述检测到的SSB信息,和6G系统同步了时间和频率,得到6G小区的时间信息,确定6G的系统信息PBCH/MIB/SI的传输参数,并接收解调6G的系统信息;6G的系统信息PBCH/MIB/SI的传输参数比如发送的时域频域资源和位置由协议预定义,5GSSB的时域频域资源位置,5G MIB/SIB1里的信息指示的至少一项决定。
