本申请涉及通信技术领域,具体涉及一种信号传输方法、设备及存储介质。
背景技术
低功耗(Low Power,LP)信号可以触发用户设备(User equipment,UE)停止执行UE上下行传输行为,也可以唤醒UE开始执行UE上下行传输行为(或称为开启主机)。终端行为包括物理下行控制信道(Physical Downlink Control Channel,PDCCH)监听、物理下行共享信道(Physical Downlink Shared Channel,PDSCH)接收和物理上行控制信道(Physical Uplink Control Channel,PUCCH)/物理上行共享信道(Physical Uplink Shared Channel,PUSCH)发送等,处于激活状态下的UE功耗高于终端睡眠状态。此外,与新空口(New Radio,NR)的主无线接收机(Main Radio,MR)相比,低功耗组件组成的低功耗接收机可以检测低功耗状态的LP信号,因此,LP信号可以为终端提供较长的休眠周期和低功耗的LP信号检测。通过考虑后向兼容性以保证UE可以通过LP接收机和/或NR主无线电接收机接收LP信号,如何提供一种由开关键控(On-Off Keying,OOK)符号和正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)序列共同生成LP信号的方案,是一个亟待解决的问题。

具体实施方式
下文中将结合附图对本申请的实施例进行说明。以下结合实施例附图对本申请进行描述,所举实例仅用于解释本申请,并非用于限定本申请的范围。
本申请的技术方案可应用于5G NR,5G-A和6G标准、基站、终端、芯片和应用。本申请的技术方案也可应用于授权(license)和非授权(unlicense)频谱,适用于双工和/或半双工,适用于TDD和/或FDD,适用于上行和/或下行链路数据传输。本申请的技术方案也可用于且不限于节能终端设备、RedCap设备、IoT设备、NB-IoT设备、Ambient-IoT设备和支持节能基站或服务小区等。
本申请说明书和权利要求中使用的“或”的描述,可用于项目列表(例如,一个项目列表采用短语,如“至少一个”或“一个或多个”)表明一个包容性的列表,例如,有A、B或C至少一个的列表,表示A或B或C或AB或AC或BC或ABC(即A和B和C)。此外,短语“基于”不得解释为指条件的一个有界闭集。例如,描述为“基于条件A”的一个示例性步骤可以是基于条件A和条件B而不脱离本申请的范围。换句话说,如本申请所用,短语“基于”应与短语“至少部分基于”或“至少基于……的一部分”相同的方式解释。
本申请说明书和权利要求中,A“与B相关联”或“与B相关”是指A包括B或B包括A或A包括B中的至少一种或B包括A中的至少一种。
针对5G系统,除了延迟、可靠性和可用性外,UE的能量效率也至关重要。目前,5G设备可能需要根据个人的使用时间每周或每天进行充电。通常,5G设备在无线资源控制(Radio Resource Control,RRC)空闲/非活动状态消耗数十毫瓦功率,在RRC连接状态消耗数百毫瓦功率。设计延长电池续航时间是提高能效和改善用户体验的必要条件。功耗取决于配置的唤醒周期长度,例如寻呼周期。为满足电池续航时间要求,可以采用价值较高的扩展不连续接收(Extended Discontinuous Reception,eDRX)周期,从而导致高延迟,不适合对电池续航时间和低延迟都有要求的此类服务。因此,提出了超低功耗唤醒(Low Power Wake up,LP-WUS)机制。
用户设备在进入超低功耗状态后,在信道时频同步方面,现有技术允许基于ZC序列、m序列和PN序列获取信道时频同步信息。例如,主同步信号(Primary Synchronization Signal, PSS)和辅同步信号(Secondary Synchronization Signal,SSS)常用于时频同步检测。因此,需要尽可能地增大低功耗信号的抗时频偏性能。
为了携带更多的指示信息和抗噪特性,可以对信息比特进行调制处理。一般用于调制原始信息比特和比特信息的调制方案包括振幅键控(Amplitude-ShiftKeying,ASK)、OOK、频移键控(Frequency-Shift Keying,FSK)、二相频移键控(Binary Phase Shift Keying,BPSK)、π/2-BPSK和正交相移键控(Quadrature Phase Shift Keying,QPSK)。此外,基于序列的调制方式可以通过序列承载指示信息。例如,利用序列携带小区标识(ID)和UE ID信息,或利用候选序列集合中的序列指示不同的触发状态。
本申请实施例提供了一种信号发送和接收方法、终端、设备及存储介质。其中,所述信号为低功耗信号。接收方法包括:用户设备接收无线网络节点发送的与低功耗信号相关的配置信息,并根据所述配置信息确定低功耗信号的监听时机。发送方法包括:根据原始信息比特和低功耗信号的资源分配情况,选择合适的资源映射方式,最终生成时域连续信号。本申请方案可以使终端通过低功耗接收机和主无线接收机检测和接收低功耗信号,并且设计生成的低功耗信号具备良好的抗时域和频域偏移的能力。
当LP-WUS采用OOK调制的时候,可以称之为OOK based LP-WUS。进一步的,当OOK信号在频域上占用的子载波(Subcarrier)数量大于1时,又称为MC-OOK,此时的LP-WUS的波形又被称为MC-OOK based LP-WUS。MC-OOK based LP-WUS可以通过如下方式生成。
MC-OOK based LP-WUS生成方法包括:
步骤1:一个OFDM符号中包括M个MC-OOK based LP-WUS符号,其中M大于等于1。
假设在M个OOK symbol上发送的数据信息为SM,定义SM=[s0,s1,s2,s3...,sM-1]且长度为M,
步骤2:按照下面的公式将SM转换为数据信息QK,其中,QK的长度为K,K大于或者等于M。例如,
或者,
其中,A0+A1+…Ai+…+AM-1=K。
其中,数据可以配置。其中,0≤i≤M-1。
步骤3:对数据信息QK做如下处理:
(1)将数据信息QK经过K point DFT/FFT操作得到数据信息DK=[d0,d1,d2,d3,...,dK-1];
(2)将数据信息DK填充到LP-WUS在频域上对应的K个子载波上;
(3)当系统频域带宽包括N个子载波时,则针对N个子载波上的填充数据,进行N point IDFT/IFFT操作,得到N个采样点的时域数据TN=[t0,t1,t2,t3,...,tn-1]。
则TN=[t0,t1,t2,t3,...,tN-1]是M个OOK时域符号的采样点数据。其中,[t0,t1,t2,t3,...,tN/M-1]为M个OOK时域符号中第一个OOK时域符号的采样点数据,[tN/M,tN/M+1,...,t2N/M-1]为M个OOK时域符号中第二个OOK时域符号的采样点数据,以此类推,[t(M-1)N/M,t(M-1)N/M+1,...,tN-1]为M个OOK时域符号中第M个OOK时域符号的采样点数据。
最后,N个采样点的时域数据TN=[t0,t1,t2,t3,...,tN-1]在发送之前还需要执行增加循环前缀(Cyclic Prefix,CP)操作,即将N个采样点的时域数据TN的尾部的Ncp个采样点信息复制到N个采样点的时域数据TN的头部,形成(N+Ncp)个采样点的时域数据,进而将这(N+Ncp)个采样点的时域数据发送出去。
在实际操作中,频域偏移会对LP-WUS的检测产生明显的影响,为了降低频域偏移对检测性能的影响,设计一种新的LP-WUS发送方法。由于OOK-based LP-WUS的频谱效率较低,新的LP-WUS生成和传输方法还能达到提高资源利用率和传输效率的目的。

在一些实施例中,如果所述序列不执行重复传输,则所述序列的映射资源大小不大于所述可用的第一位置的映射资源大小。
在一些实施例中,如果所述序列执行重复传输或跳频传输,则所述一次传输的序列的映射资源大小与所述可用的第一位置的映射资源大小为倍数关系。
在一些实施例中,第一类指示信息比特数目为N1,第一类指示信息对应的CRC比特数目为NCRC,每比特信息对应M1比特的码字,序列指示的信息比特数目为N2。在一些实施例中,所述候选序列中的任一条序列可指示的比特信息数目不少于

在一些实施例中,function(·)表示对输入‘·’进行向上取整、向下取整、四舍五入取整或保留原值的至少之一操作。
在一些实施例中,UE根据所述序列所需指示的(最少)比特数目从多个候选序列或多个候选池中确定用于指示信息的候选序列或候选序列池。
图17a是本申请实施例提供的一种确定传输所采用序列的实现示意图。如图17a所示,预定义候选序列池中,候选序列池i包括2i条序列(如候选序列池1中包括2条序列,可指示1bit信息)。根据确定的序列最少指示1bit信息,以及候选序列池信息,最终从所有候选序列池中选择序列池1作为序列传输所用的序列池。图17b是本申请实施例提供的一种确定传输所采用序列的实现示意图。如图17b所示,预定义候选序列中,每个序列对应1个序列索引(从小到大排列),序列0~序列(2i-1)条序列可指示i比特信息。根据确定的序列最少指示1bit信息,以及候选序列池信息,最终从所有候选序列中选择序列0和序列1作为序列传输所用的序列。
图18是本申请实施例提供的一种序列池中选取传输所用序列的实现示意图。如图18所示,举例N1=4bits,NCRC=4,M1=1;N2=2bits。由于N1和NCRC相等,则无论序列映射在CRC比特部分还是映射在第一指示信息比特部分,候选序列至少指示ceil(0.5)=1bit。如果候选序列中任一序列可指示1bit信息,则候选序列至少包含两条序列(即21=2)。由上述参数可知,可用的第一位置的映射资源大小是序列传输所需映射资源大小的2倍。
在一些实施例中,所述候选序列中的任一条序列可指示的比特信息数目不大于2比特。
在本文中,function(·)表示对“·”进行向上取整、向下取整、四舍五入取整或保留原值中的至少之一操作。
在第十实施例中,基站配置1个符号或1个第一位置承载的序列可指示的比特数量(记为N2),UE根据对应的序列池中的序列检测LP-WUS。
可选的,如果第一位置的数量小于序列所需的第一位置数量,则UE默认扩展候选序列数量直到第一位置对应的映射资源满足序列传输所用的映射资源为止。
例如,第一类信息共2bits,CRC比特数目为4,1/2曼彻斯特编码,第一位置数量为6。序列所需承载的比特数目为24bits,基站配置序列可指示2bits(共4条候选序列,此时即使占满所有第一位置也只能传输12bits信息),则UE扩展候选序列数目至16条,此时可传输24bits信息。
可选的,如果1个符号内第一位置的数量大于需要承载的序列数量,则UE假设序列在第一位置上按照默认的单次传输方式、重复传输方式或跳频方式传输。
可选的,第一位置数量大于序列所需第一位置数量时,如果基站配置序列可重复传输,则UE默认序列可指示N2比特信息,并在额外的或剩余的第一位置上重复传输。
可选的,第一位置数量大于序列所需第一位置数量时,如果基站未配置序列可重复传输且第一位置数量满足序列指示更少比特或1比特传输所需第一位置数量,则UE默认序列可指示1比特信息。可选的,UE仅使用候选序列中的前两条序列作为传输所用序列执行相关检测。
在第十一实施例中,第一位置和序列之间包含多种映射关系。
在一些实施例中,一种资源映射方法包括序列按照一种特定的映射方式映射在一个或多个第一位置的映射资源上。其中,一种特定的映射方式包括重复(repetition)、跳频(hopping)、满映射和分段映射。所述映射方式均按照逐资源粒子映射(RE mapping)。
分段映射:
在一些实施例中,所述分段映射的映射方式是指序列占用的资源大小与第一位置或特定码字的第一位置占用的资源大小不同,或序列占用第一位置或特定码字的第一位置占用的资源的一部分。其中,资源大小包括被分配的时域资源、频域资源、扩频码资源、扰码资源或空域资源中的至少之一。
在一些实施例中,一个序列映射在多个第一位置占用的RB集上,或序列的其中一个频域分段映射在一个第一位置占用的RB集上,或多个序列映射在一个第一位置占用的RB集上。
在一些实施例中,一个序列的映射资源是一个第一位置或特定码字的第一位置的映射资源的整数倍。
图19是本申请实施例提供的一种序列分段映射在OOK-4符号的两个第一位置的实现示意图。如图19所示,将第二序列分成两个分段,分别为第一分段和第二分段,然后将第一分段和第二分段分别映射在OOK-4符号的两个第一位置上。图19中所示的第一序列表示OOK-4符号中仅包括一次高电平和低电平跳变的信号部分,或仅包括一个第一位置的部分。
在一些实施例中,对于映射在一个第一位置的映射资源上的多个序列,所述多个序列中的两个序列或两个序列的频域分段或序列的两个跳频映射在相邻频域资源上。在一些实施例中,所述两个序列的频域分段映射的相邻频域资源之间间隔不小于α个SCS、RE或PRB,或相邻时域资源之间间隔不小于1个OFDM symbol。其中,α为不小于1且不大于2*S的整数。
图20是本申请实施例提供的一种序列分段映射的实现示意图。如图20所示,将同一个第二序列的两次重复以跳频的方式映射在相邻的频域资源上。

在一些实施例中,第一位置占用的RB数量不小于第二位置占用的RB数量。在一些实施例中,第一位置占用的物力资源块(resource block,RB)数量和频域位置与第二位置占用的RB数量和频域位置相同。
满映射:
在一些实施例中,所述满映射的映射方式是指第一位置和序列占用的资源大小相同。其中,所述资源大小包括频域资源起始RB位置和RB数目。
在一些实施例中,如果序列映射在第一位置的映射资源(至少包括RB)上,所述序列的相邻2个跳频占用的RB集合不重叠且无RB/子载波间隔。
在一些实施例中,在第一时期内,第一序列可配置的最大资源数不超过64。
在一些实施例中,第一指示信息和第二指示信息比特数目相同,或一个OOK和一个序列可指示的信息比特数目相同。
在一些实施例中,第一指示信息对应生成的码字中非0元素占用的资源定义为可用映射资源。
在一些实施例中,第一指示信息对应的可用映射资源集大于所有序列占用的总资源,这时要满足以下至少之一的资源映射规则:
1)将所有序列按照从时间先后顺序和/或子载波/RE/RB的先后顺序进行资源映射;或
2)将所有序列按照每间隔n段第一位置或n个码字的要求进行先时域后频域的资源映射,其中,n为大于等于0的整数;或
3)每个码字中仅n段连续非0元素或n个非0码元可用于序列的资源映射,其中,n为大于等于0的整数;或
4)以每个序列占用的资源集为单位,按照行进列出的交织方式对序列的资源集进行交织后以顺序映射的方式映射到可用资源上;或
5)以每个码字提供的一段连续的非0元素的映射资源为单位,按照交织后的资源索引进行资源映射。
例如,图22是本申请实施例提供的一种序列交织映射的实现示意图。如图22所示,如果承载第一指示信息的第一序列可提供7个可用的资源集,共生成4个序列占用4个资源集,则参与资源映射的序列按照行进列出的方式交织。其中,每个资源集为一个第一位置或一个码字占用的总的映射资源。
在一些实施例中,OOK符号第一位置上承载序列的传输方法应用于OOK-1操作模式下或应用于M=1或M=2的OOK-4操作模式下。
在第十二个实施例中,一种指示信息校验方法包括基于第一序列的相关解调、基于第二序列的相关解调和循环冗余校验至少之一。其中,第一指示信息在检测到第二指示信息之后完成接收。
方法1:基于第一序列传输第一指示信息时,生成对应的CRC比特信息。所述CRC比特信息由第一序列承载。
在一些实施例中,如果第二序列未携带第二指示信息,则第一指示信息的CRC校验步骤在检测到第二序列或接收完成第二序列指示信息后执行。
在一些实施例中,如果第二序列携带了第二指示信息,则所述第二序列在承载CRC比特的第一位置的映射资源上传输。
在一些实施例中,如果第二序列携带了第二指示信息,则第二指示信息对应的CRC比特信息由第二序列承载。在一些实施例中,所述承载第二指示信息对应的CRC比特信息的第二序列在承载CRC比特的第一位置的映射资源上传输。
方法2:基于第一序列传输第一指示信息时,生成对应的CRC比特信息。所述CRC比特信息由第二序列承载。
在一些实施例中,如果第二序列不用于承载第二指示信息,则为了提高频谱资源利用率,缩短检测时间,第二序列可用于承载第一指示信息对应的CRC比特信息。
在一些实施例中,第二序列用于承载第一指示信息对应的CRC比特信息。所述第二序列在承载第一指示信息的第一位置的映射资源上传输;或所述第二序列在承载第一指示信息的第一序列的映射资源之后的相邻资源上传输。

在一些实施例中,所述映射规则包括实施例1中所述的映射方式中的至少之一。图23是本申请实施例提供的一种序列间隔映射的实现示意图。如图23所示,将两个序列分别映射在第一序列的第一个第一位置和第三个第一位置上。

在一些实施例中,如果第一类指示信息和序列指示的信息相同,则UE至少检测OOK符号和序列中的一种。在一些实施例中,如果UE被配置第一类指示信息和序列指示的信息相同,且UE执行基于序列检测得到的指示信息与基于OOK符号检测得到的指示信息不同,则UE按照有CRC校验比特或CRC校验通过的指示信息作为最终检测到的指示信息;否则,如果第一类指示信息和序列指示的信息的CRC校验都成功,则UE按照序列检测得到的指示信息作为最终检测到的指示信息。
可选的,UE根据基站配置确定第一类指示信息和序列指示的信息中的一种指示信息检测有效。

UE根据高层配置参数确定是否在第一位置映射序列或确定序列是否承载指示信息。
在一些实施例中,根据高层配置确定是否进行比特信息分类。如果高层配置UE支持两种低功耗波形指示不同信息,则进行比特信息分类;否则,如果高层配置UE支持两种低功耗波形指示相同信息,则生成可承载完整指示信息的两种波形的低功耗信号;否则,如果高层配置UE仅支持一种低功耗波形指示,则采用所配置的波形生成低功耗信号。
图24是本申请实施例提供的一种低功耗信号指示应用时延的实现示意图。如图24所示,在一些实施例中,如果第一序列携带的第一指示信息比特数目N1>0,或序列携带的第二指示信息比特数目N2>0,则UE在一个应用时延1之后应用第一指示信息,UE在一个应用时延2之后应用第二指示信息。其中,应用时延1不小于应用时延2。
在一些实施例中,如果第一序列携带的第一指示信息比特数目N1>0,序列携带的第二指示信息比特数目N2=0,则UE在一个应用时延1之后应用该指示信息。其中,应用时延2为0。
在一些实施例中,如果序列用于承载第一指示信息对应的CRC比特,则第一指示信息的应用时延为应用时延1或应用时延1和应用时延2的累加。
