背景技术

具体实施方式
下面结合附图对本公开提供的信息传输方法和装置、信息确定方法和装置、电子设备、计算机可读存储介质进行描述。
在下文中将参考附图描述示例实施例,但是所述示例实施例可以以不同形式来体现且不应当被解释为限于本文阐述的实施例。提供这些实施例的目的在于使本公开透彻和完整。
如本文所使用的,术语“和/或”包括至少一个相关列举条目的任何和所有组合。
本文所使用的术语仅用于描述特定实施例,且不意欲限制本公开。如本文所使用的,单数形式“一个”和“该”也意欲包括复数形式,除非上下文另外指出。当本文中使用术语“包括”和/或“由……制成”时,指定存在所述特征、整体、步骤、操作、元件和/或组件,但不排除存在或添加至少一个其它特征、整体、步骤、操作、元件、组件和/或其群组。
除非另外限定,否则本文所用的所有术语(包括技术和科学术语)的含义与本领域普通技术人员通常理解的含义相同。诸如那些在常用字典中限定的那些术语应当被解释为具有与其在相关技术以及本公开的背景下的含义一致的含义,且将不解释为具有理想化或过度形式上的含义,除非本文明确如此限定。
第五代移动通信技术(the 5th Generation mobile communication technology,5G)的成熟将进一步支持增强的移动宽带(eMBB,Enhanced Mobile Broadband)、高可靠性和超低时延的通信(URLLC,Ultra-Reliable and Low Latency Communication)以及大规模机器通信(MMTC,Massive Machine Type of Communication)等三大应用场景。在系统性能方面,5G系统将具备10~20Gbit/s的峰值速率,每平方公里100万的连接数密度,1ms的空口时延,500km/h的移动性支持,每平方米10Mbit/s的流量密度等关键能力指标。为了能够使系统容量满足上述愿景,5G采用了更高频率的频谱资源,相对4G提升3~5倍的频谱效率。
业内对5G非授权频谱进行了立项研究,提出了支持非授权小区单独组网的立项。国际电信联盟(International Telecommunication Union,ITU)会议讨论了66-71GHz、71-76GHz、81-86GHz三个候选频段。美国已经将66-71GHz作为非 授权频段,欧洲也有将其作为非授权的趋势。在高频段(52.6GHz以上)的非授权频谱设计上,需要考虑同步信号物理广播信道块(SS/PBCH Block,SSB)传输面临的一些新问题。相关技术中,SSB基于多载波通信系统设计,由PSS、SSS、PBCH和DMRS组成,其中,DMRS与PBCH能够频分复用。多载波系统的问题是:最大瞬时功率与平均功率比值较大,且对频率偏移、相位噪声敏感,以上问题在高频中更为突出。单载波通信系统能够缓解上述问题,并且单载波系统相较于多载波系统硬件损耗造成的影响也较低。然而,单载波系统中不允许PBCH和DMRS在频域资源上复用,单载波系统中如何传输SSB尚未有有效解决方案。
图1为本公开实施例提供的一种无线传输方法的流程图。
参照图1,本公开实施例提供一种无线传输方法,可以应用于单载波通信节点,该方法包括:
步骤100、传输SSB;其中,所述SSB中包括的信号和信道被以时分复用的方式映射到M个连续的时域符号中,M为正整数;所述SSB包括:PBCH、PSS和SSS。
在一些实施例中,传输包括以下至少之一:发送、接收。
在一些实施例中,M为3、4、5中的任意一个。
在一些实施例中,SSB还包括:DMRS。
在一些实施例中,所述SSB的特征包括以下至少之一:
所述SSB中包括的每一个信号被映射到所述信号所在时域符号的至少一个资源块(RB,Resource Block)或至少一个资源元素(RE,Resource Element)中,所述SSB中包括的每一个信道被映射到所述信道所在的时域符号的至少一个RB或至少一个RE中;所述PBCH所在的时域符号的所有RB或RE和映射有所述DMRS的RE之间的交集为空,在一些实施例中,任意一个信号或信道所在的时域符号的所有RB和映射有其他任意一个信号或信道的RE之间的交集为空;所述DMRS占用的带宽大于或等于每一个映射有PBCH的时域符号中承载的所述PBCH占用的带宽;所述SSS占用的带宽大于或等于每一个映射有PBCH的时域符号中承载的所述PBCH占用的带宽;所述SSS被交叉映射到所述SSS所在时域符号的RB或RE中,其中,所述交叉映射包括:仅映射到所述SSS所在时域符号的奇数RB或奇数RE中,或者,仅映射到所述SSS所在时域符号的偶数RB或偶数RE中;所述SSS被映射到所述SSS所在时域符号的所有RB或RE中;所述PSS、所述SSS、所述DMRS分别被映射到一个时域符号中;所述PSS、所述SSS分别被映射到一个时域符号中;所述PBCH被映射到 至少一个时域符号中;所述PBCH被映射到DMRS符号的前后各一个时域符号中;PBCH符号与所述DMRS符号相邻;至少一个PBCH符号与SSS符号相邻;其中,所述DMRS符号为映射所述DMRS的时域符号,所述PBCH符号为映射所述PBCH的时域符号,所述SSS符号为映射所述SSS的时域符号。
在一些实施例中,RB是指频域上的RB,也就是说,RB包括频域上连续的12个子载波。
为了实现PBCH参考DMRS进行解调,需要DMRS占用的带宽大于或等于每一个时域符号中承载的所述PBCH占用的带宽;同样的,为了实现PBCH参考SSS进行解调,需要SSS占用的带宽大于或等于每一个时域符号中承载的所述PBCH占用的带宽。
当PBCH参考DMRS进行解调时,PBCH符号和DMRS符号相邻提高了精度;当PBCH参考SSS进行解调时,PBCH符号和SSS符号相邻提高了精度。
上面所列出的SSB的特征可以随意组合。
在一些实施例中,所述SSB的特征包括:
所述SSB中包括的每一个信号被映射到所述信号所在时域符号的至少一个资源块RB或至少一个资源元素RE中;所述SSB中包括的每一个信道被映射到所述信道所在的时域符号的至少一个RB或至少一个RE中;所述PBCH所在的时域符号的所有RB或RE和映射有所述DMRS的RE之间的交集为空;所述DMRS占用的带宽大于或等于所述PBCH占用的带宽;所述PSS、所述SSS、所述PBCH和所述DMRS分别被映射到一个时域符号中;PBCH符号与所述DMRS符号相邻;其中,所述DMRS符号为映射所述DMRS的时域符号,所述PBCH符号为映射所述PBCH的时域符号。
在一些实施例中,所述SSB的特征包括:

还有很多其他的映射方案,只要满足上述SSB的特征就可以,满足上述SSB的特征的映射方案均在本公开实施例的保护范围内。
本公开实施例提供的无线传输方法,采用时分复用的方式将SSB中包括的信号和信道映射到M个连续的时域符号中进行传输,实现了单载波系统中SSB的传输。
对于SSB结构,PBCH的解调需要借助DMRS,单载波的系统不允许二者在频域资源上复用,潜在的解决方式是PBCH借助临近的PSS或者SSS进行解调,或者单独引入DMRS符号进行解调。因此,单载波系统中传输的SSB可以包括DMRS,DMRS作为PBCH的解调的参考;SSB也可以不包括DMRS,而 借助临近的PSS或者SSS对PBCH进行解调。

还有很多其他的映射方案,只要满足上述SSB的特征就可以,满足上述SSB的特征的映射方案均在本公开实施例的保护范围内。
本公开实施例的无线传输装置,基于SSB整合PDCCH和PDSCH形成广播信号信道块(BSCHB,Broadcast Signal CHannel Block),有更益于适应波束的发送,并且,采用时分复用的方式将广播信号信道块中包括的信号和信道映射到7N个连续的时域符号中进行传输,实现了单载波系统中广播信号信道块的传输。
相关技术中,DMRS通常采用频分复用的方式将DMRS序列插入到其他信道中,在其他信道参考DMRS进行解调时,参考DMRS序列进行解调参考,单载波系统中DMRS不能采用频分复用的方式,上述方式不适用;多载波系统中当DMRS不是采用频分复用时,上述方式同样不适用。

在一些实施例中,第一频率偏移量、所述位置参考信道被映射到的频域位置中的最低RE和待解调信道被映射到的频域位置中的最低RE之间的第二频率偏移量和第三频率偏移量可以通过RRC信令配置直接配置为固定值;或者,也可以先通过协议预定义其候选值,再通过RRC信令选择取值;或者,也可以通过协议预定义为固定值。

例如,可以是前述实施例中提出的SSB或广播信号信道块,也可以是其他的信号信道结构,本公开实施例对此不作限定。
如图13,以PDCCH为待解调信道,PBCH为位置参考信道举例。PDCCH参考DMRS中的一段参考序列进行解调,其中PBCH的频域位置已知,确定所述DMRS的频域参考点的方法包括以下至少之一:

所述offset1与offset2配置方法是如下之一:
通过RRC信令配置,直接配置确定的offset值;通过协议预定义确定offset候选值,通过RRC信令选择offset值;通过协议预定义确定,直接定义确定的offset值。
方法(a-f)以信道信号最低RE或者RB作为基准点,同样的,最高RE或者RB也可以作为基准点;根据基准点偏移的方向可以是朝向低频方向,也可以是朝向高频方向。类似方法不做赘述。
