前导序列的发送和接收方法、装置及存储介质

背景技术
随着移动通信的发展变化,多个国际组织都在开始研究新的无线通信系统,即6G系统,连接设备数量的增长,是6G的重要驱动力之一,巨量终端的初始接入和数据传输,将受限于网络的协调资源。
非协调随机接入和传输(Uncoordinated Random Access and Transmission,URAT)技术由于不需要或仅需要很少的协调资源而能够支持巨量终端。但是,URAT技术中,终端的接入过程和数据发送过程一起进行,这样就要求前导序列(Preamble)与物理上行共享信道(Physical Uplink Shared Channel,PUSCH)相关联,即前导序列需要承载与PUSCH相关的数据信息,PUSCH的性能受到前导序列性能的影响,只有前导序列解对时才能进行PUSCH的求解。因此,如何提升前导序列性能是亟待解决的问题。

URAT技术主要特征是不需要网络协调、同时实现随机接入和多址传输两个过程,其中,不需要网络协调是指不需要网络确认终端的接入身份、不需要网络调度传输资源。如 图1所示为URAT技术的原理示意图。图1中,附加比特是基于信息比特生成的,例如附加比特是信息比特的最后A个比特,又如,附加比特是信息比特的循环冗余校验比特。终端按照周期发送前导序列和数据序列,直到达到数据序列的最大发送次数,或者接收到基站反馈的确认信息,指示网络已正确接收信息比特,或网络广播发送的停止接入传输的信息。URAT技术是随机接入技术和多址传输技术的融合升级,不再把初始接入和数据传输作为两个独立的过程,而是融合成一个过程,以支持巨量终端的接入和传输、降低时延、提高接入和传输的成功率。由于前导序列需要承载信息比特的相关信息,因此,如何提升前导序列性能是URAT技术中亟待解决的问题。
以下先对承载前导序列的资源进行介绍。如图2所示,在每一个物理随机接入信道(Physical Random Access Channel,PRACH)时隙之内,网络可以配置一个或多个随机接入信道时机(RACH Occasion,RO),进行PRACH发送的RO称为PRACH时机(PRACH Occasion)。PRACH Occasion即为承载前导序列传输的时频资源。本申请实施例中后续所描述的RO指的是进行PRACH发送的RO,即PRACH Occasion。
如图3所示,在频域上,NR支持配置1、2、4或8个频分复用(Frequency-division multiplexing,FDM)的PRACH资源,以扩充PRACH容量,当在频域上配置的PRACH资源为1个以上时,这些PRACH资源在频域连续分布。图3中示意了PRACH_FDM=4的场景,PRACH_FDM为PRACH资源的频分复用数量,PRACH_FDM=4即PRACH资源在频域上频分复用4个RO。在一种实施方式中,网络侧还可以通知频域上第一个PRACH Occasion资源的起始物理资源块(Physical Resource Block,PRB)相对于子带宽(Bandwidth Part,BWP)的起始PRB的偏移。
在UE发起随机接入之前,UE对小区的信号质量以及小区中的各个同步信号块(Synchronization Signal Block,SSB)的信号强度会进行测量评估。在发起PRACH时,UE选择在对应信号最强或较强的SSB所对应的PRACH occasion上发送前导序列。网络若成功接收前导序列,就基于前导序列所在PRACH occasion获知向UE发送下行信息的下行波束信息,进而使用该波束信息进行后续通信,例如发送msg2、msg4等。
SSB与PRACH occasion之间存在多种可能的比例关系:1)一对一映射;2)多对一映射;3)一对多映射。系统中有多个实际传输的SSB以及多个配置的PRACH occasion,网络侧与UE均需要获知每一个SSB与哪些PRACH occasion对应。
在NR中SSB与进行PRACH发送的RO,即PRACH occasion的映射采用频域优先的设计,多个SSB可以依照如下的顺序被映射至PRACH occasion:
(1)每一个PRACH occasion之内依据前导序列索引递增的顺序;
(2)依据FDM的PRACH occasion的编号递增的顺序;
(3)在一个PRACH时隙内依据时分复用的PRACH occasion的编号递增的顺序;
(4)依据PRACH时隙的递增顺序。
对于基站仅能接收单个波束的场景,可将频分复用的多个PRACH occasion配置为对应同一个SSB。
以8个SSB,PRACH_FDM=4为例进行说明,PRACH_FDM=4即如图3所示PRACH资源在频域上频分复用4个RO,图4给出了不同SSB_per_RO(1/4,1/2,1,2,8)时的SSB与RO的映射关系,以SSB_per_RO=N进行表示,其中,N小于1时,SSB_per_RO=N 表示每个SSB映射的RO数量为1/N,例如,SSB_per_RO=1/4表示每个SSB映射的RO数量为4,由于PRACH_FDM=4,则一个SSB可以映射到一个时域RO(该时域RO在频域上由4个RO组成,也就是说一个SSB映射到频域上的4个RO组成的一个时域RO)。N大于或等于1时,SSB_per_RO=N表示每个RO映射的SSB数量为N,每个SSB映射的RO数量为1,例如,SSB_per_RO=2表示每个RO映射的SSB的数量为2,一个SSB映射到1个RO,由于PRACH_FDM=4,则8个SSB可以映射到一个时域RO(频域上由4个RO组成)。
在NR中,可以根据ssb-perRACH-Occasion(ssb-perRACH-OccasionAndCB-PreamblePerSSB)确定每个RO映射的SSB数量或每个SSB映射的RO数量(也可以通过其他参数获得,例如msgA-SSB-perRACH-OccasionAndCB-PreamblePerSSB、CFRA中的相关参数等),例如ssb-perRACH-Occasion可以配置为{1/8,1/4,1/2,1,2,4,8,16}。当N的取值小于1时,每个SSB可以与1/N个RO关联。当N的取值大于或等于1时,每个SSB与1个RO关联。
相关技术中,当UE选择的SSB映射至多个RO时,UE随机选择一个RO来发送前导序列。而在本公开中,由于URAT技术中前导序列需要承载信息比特的相关信息,为了提升前导序列性能,可以选择在一个或多个SSB对应的多个RO上发送前导序列。
为此,本公开实施例提供一种前导序列的传输方法,该方法中,UE根据检测到的SSB确定多个RO,并在这多个RO上发送前导序列,该前导序列承载了根据信息比特生成的附加比特,从而提高了URAT技术中的前导序列性能。
图5为本公开实施例提供的前导序列的发送方法的流程示意图。如图5所示,该方法包括:
S501、根据检测到的SSB确定M个RO,M为大于1的整数。
URAT中,UE进行前导序列发送时,可以对SSB突发(burst)进行检测,根据检测到的每个SSB的同步信号-参考信号接收功率(Synchronization Signal Reference Signal Received Power,SS-RSRP),从所有检测到的SSB中选择合适的SSB,例如选择SS-RSRP最大的1个或多个SSB,再例如选择SS-RSRP大于预设阈值的一个或多个SSB,基于选择的SSB,确定前导序列使用的多个RO。即,UE至少根据检测到的SSB的SS-RSRP,从检测到的SSB中选择X个SSB,X为大于或等于1的整数,X可以是预设的,或者是网络设备配置的,或者是协议约定的,或者是由UE自行确定的;根据SSB与RO之间的映射关系以及该X个SSB,确定M个RO,M可以是预设的,或者是网络设备配置的,或者是协议约定的,或者是由终端确定的。除SS-RSRP之外,UE也可以结合其他信息来选择X个SSB,本实施例对此并不限定。
S502、在M个RO上发送前导序列,前导序列承载了根据信息比特生成的附加比特。
如前述所介绍的,URAT中,前导序列承载了信息比特的信息,参照图1,也就是前导序列承载了根据信息比特生成的附加比特,信息比特包括用户身份信息和用户数据信息。UE在M个RO上发送前导序列,可选的,M个RO上的前导序列可以是相同的,即前导序列承载了附加比特的全部信息,通过M个RO重复发送前导序列,从而提升URAT技术中的前导序列性能。可选的,M个RO上的前导序列可以是不完全相同的,每个前导序列 承载了附加比特的部分信息。例如,M为4,4个RO中,2个RO上的前导序列相同,称为第一前导序列,另外2个RO上的前导序列相同,称为第二前导序列,第一前导序列和第二前导序列不同,第一前导序列和第二前导序列各自承载附加比特的部分信息,第一前导序列和第二前导序列共同承载了附加比特的全部信息。前导序列承载附加比特的部分信息时,需要的前导序列候选集中的元素个数(2^b,b为前导序列所承载的部分附加比特的比特数)也相应较少,从而可以降低前导序列的检测复杂度,同时在更少的候选集中检测可以提升前导序列的检测性能。
在上述实施例的基础上,结合示例对如何选择SSB和RO进行说明。以下示例中均以8个SSB,PRACH_FDM=4为例。
在一种实施方式中,若每个SSB映射的RO数量为1/N,N小于1,则M个RO表示X个SSB对应的X/N个RO。
参照图6,SSB_per_RO=1/4,即,网络设备配置的每个SSB映射的RO数量为4。UE首先根据检测到的SSB的SS-RSRP,从检测到的SSB中选择X个SSB,例如,该X个SSB表示所有SSB中SS-RSRP最大的X个SSB,或者,该X个SSB表示SS-RSRP超过预设阈值的X个SSB。例如,X为1,8个SSB中SSB4对应的SS-RSRP最大,UE选择SSB4作为该X(X为1)个SSB,并选择SSB4所映射的4个RO作为确定出的M(M为4)个RO。例如,X为2,8个SSB中SSB4和SSB5对应的SS-RSRP为最大的两个,UE选择SSB4和SSB5作为该X(X为2)个SSB,并选择SSB4和SSB5所映射的8个RO作为确定出的M(M为8)个RO。
以X为2为例,UE在选择SSB4和SSB5所映射的8个RO后,可以在该8个RO上发送前导序列,这8个RO上的前导序列可以相同或者不完全相同。
可选的,8个RO上的前导序列不完全相同的场景中,UE根据M,确定对附加比特进行分段的分段数L;在M个RO上发送L个前导序列,L个前导序列中的每个前导序列承载一个附加比特分段。可选的,L小于或等于M。例如,L的取值可以等于M,又如,L可以是根据M进行计算得到的,例如L为M除以P后向上取整,P可以是预设的,或者是网络设备配置的,或者是协议约定的,或者是由终端确定的,例如P=2。不同附加比特分段对应的前导序列传输次数可以相等或不等。
在一种实施方式中,若每个SSB映射的RO数量为1/N,N小于1,则X等价于M除以1/N再向上取整,M个RO表示X个SSB对应的X/N个RO中的M个。
本实施方式中,UE基于M的值从检测到的SSB中选择X个SSB,M的值可以是协议约定的,或者是网络设备配置的,或者是协议约定的,或者是由终端确定的,其中,终端可以是自行确定的,或者根据网络设备配置的相关参数确定的。参照图7,SSB_per_RO=1/2,即,网络设备配置的每个SSB映射的RO数量为2。
假设M为4,则UE需要选择的SSB的个数X为2,该X个SSB表示所有SSB中SS-RSRP最大的X个SSB,或者,该X个SSB表示SS-RSRP超过预设阈值的X个SSB。例如,8个SSB中SSB2、SSB4对应的SS-RSRP为最大的两个,则UE选择SSB2、SSB4作为该X(X为2)个SSB,并选择SSB2、SSB4所映射的4个RO作为确定出的M(M为4)个RO。
假设M为3,则UE需要选择的SSB的个数X为2,该X个SSB是所有SSB中SS-RSRP 最大的X个SSB,或者,该X个SSB是SS-RSRP超过预设阈值的X个SSB。例如,8个SSB中SSB2、SSB4对应的SS-RSRP为最大的两个,则UE选择SSB2、SSB4作为该X(X为2)个SSB,并选择SSB2、SSB4所映射的4个RO中的3个RO作为确定出的M(M为3)个RO。
以M为4为例,UE在选择SSB2、SSB4所映射的4个RO后,可以在该4个RO上发送前导序列,这4个RO上的前导序列可以相同或者不完全相同。
可选的,4个RO上的前导序列不完全相同的场景中,一种实现方式中,UE根据M,确定对附加比特进行分段的分段数L;在M个RO上发送L个前导序列,L个前导序列中的每个前导序列承载一个附加比特分段。可选的,L小于或等于M。这种方式中,UE是在确定出M个RO后,再根据M的值确定分段数L。
在另一种实现方式中,UE可以先确定对附加比特进行分段的分段数L,再根据分段数L确定M,可选的,M小于或等于L。可选的,分段数L可以是协议约定的,或者网络设备指示的,或者是UE根据网络设备配置的参数确定的,或者UE自行确定的,例如UE根据附加比特数确定L。可选的,M的取值可以与L相等。可选的,M的取值可以根据L计算获得,例如M为L乘以P,P可以是一个预设的,或者是网络设备配置的,或者是协议约定的,或者是由终端确定的,例如P=2。即,UE先确定L,再基于分段数L确定出M,进而采用本实施方式的方法确定出M个RO,并采用这M个RO发送L个前导序列。
在一种实施方式中,若每个SSB映射的RO数量为1,每个RO映射的SSB数量为N,N大于或等于1,则X为1,X个SSB表示所有SSB中SS-RSRP最大的一个SSB,或者,X个SSB表示SS-RSRP超过预设阈值的一个SSB。UE根据SSB与RO之间的映射关系以及X个SSB,确定M个RO,包括:根据SSB与RO之间的映射关系确定X个SSB对应的第一RO;以第一RO为起点,选择连续的M个RO。
本实施方式中,M的值可以是协议约定的,或者是网络设备配置的,或者是协议约定的,或者是由终端确定的,其中,终端可以是自行确定的,或者根据网络设备配置的相关参数确定的。参照图8,SSB_per_RO=2,即,网络设备配置的每个RO关联的SSB的个数N为2,每个SSB映射的RO数量为1。假设M为4,8个SSB中SSB4对应的SS-RSRP最大,终端选择SSB4作为选择的X(X为1)个SSB,将SSB4对应的RO作为第一RO,从而以SSB4对应的RO为起点,选择连续的4个RO作为确定出的M(M为4)个RO。UE在选择这4个RO后,可以在该4个RO上发送前导序列,这4个RO上的前导序列可以相同或者不完全相同。在前导序列不完全相同的场景中,UE对附加比特进行分段的实现方式与前述类似,此处不再赘述。
在一种实施方式中,若每个SSB映射的RO数量为1,每个RO映射的SSB数量为N,N大于或等于1,则X等于M,X个SSB表示所有SSB中最大的M个SS-RSRP对应的M个SSB,或者,X个SSB表示SS-RSRP超过预设阈值的M个SSB;UE根据SSB与RO之间的映射关系以及X个SSB,确定M个RO,包括:根据SSB与RO之间的映射关系,确定X个SSB对应的K个RO,若K等于M,则将K个RO确定为M个RO;若K小于M,则继续选择除X个SSB之外的其他SSB中,最大的SS-RSRP对应的SSB所对应的RO,直至确定出M个RO,或者,则从K个RO之后再选择连续的M-K个RO,以得到M个RO。
本实施方式中,M的值可以是协议约定的,或者是网络设备配置的,或者是协议约定的,或者是由终端确定的,其中,终端可以是自行确定的,或者根据网络设备配置的相关参数确定的。参照图9,SSB_per_RO=1,即,网络设备配置的每个RO关联的SSB的个数N为1,每个SSB映射的RO数量为1。假设M为4,8个SSB中SSB2、SSB4、SSB6、SSB8对应的SS-RSRP为最大的4个,终端选择SSB2、SSB4、SSB6、SSB8作为选择的X(X为4)个SSB,SSB2、SSB4、SSB6、SSB8对应的RO的个数K为4,即K等于M,因此,将SSB2、SSB4、SSB6、SSB8对应的4个RO作为确定出的M(M为4)个RO。UE在选择这4个RO后,可以在该4个RO上发送前导序列,这4个RO上的前导序列可以相同或者不完全相同。
参照图10,SSB_per_RO=2,即,网络设备配置的每个RO关联的SSB的个数N为2,每个SSB映射的RO数量为1。假设M为4,8个SSB中SSB1、SSB2、SSB3、SSB4对应的SS-RSRP为最大的4个,终端选择SSB1、SSB2、SSB3、SSB4作为选择的X(X为4)个SSB,SSB1、SSB2、SSB3、SSB4对应的RO的个数K为2,即K小于M,因此,除了SSB1、SSB2、SSB3、SSB4对应的2个RO之外,UE继续选择除这2个SSB之外的其他SSB中,最大的SS-RSRP对应的SSB所对应的RO,直至确定出M个RO,例如,假设除了SSB1、SSB2、SSB3、SSB4对应的2个RO,SSB5和SSB7对应的SS-RSRP最大,则UE继续选择SSB5和SSB7对应的2个RO,从而一共选择出4个RO。或者,则从SSB1、SSB2、SSB3、SSB4对应的2个RO之后,再选择连续的2个RO,从而得到4个RO。
UE在选择4个RO后,可以在该4个RO上发送前导序列,这4个RO上的前导序列可以相同或者不完全相同。在前导序列不完全相同的场景中,UE对附加比特进行分段的实现方式与前述类似,此处不再赘述。
本公开实施例中,根据SSB与RO的映射关系,确定多个RO进行前导序列的传输,与使用一个RO进行前导序列传输相比,能够提升前导序列传输的性能。此外,对附加比特进行分段,采用不同前导序列传输不同的附加比特分段,能够减少单个前导序列承载的信息,从而减小前导序列候选集中的序列个数,从而可以降低检测复杂度,同时在更少的候选集中检测可以提升前导序列的检测性能。
图11为本公开实施例提供的前导序列的接收方法的流程示意图。如图11所示,该方法包括:
S1101、确定一种或多种RO组合,RO组合包括M个RO,M为大于1的整数。
对于网络设备,由于缺少终端使用的SS-RSRP信息,因此网络设备在接收前导序列时只能对RO进行盲检测,本公开实施例中,终端通过多个RO发送前导序列,因此网络设备先确定出由M个RO组成的RO组合,以便于进行检测。M可以是网络设备为终端配置的用于发送前导序列的RO的数值,或者是协议约定的,或者是网络设备从候选值中确定的。
S1102、在每种RO组合上进行前导序列的接收处理,前导序列承载了附加比特,附加比特是根据信息比特生成的。
对于确定的所有由M个RO组成的RO组合,网络设备均需要进行接收处理,以获取终端通过M个RO发送的前导序列。可选的,在接收前导序列后,对前导序列承载的附加 比特进行求解。

以第一RO为起点,选择连续的M个RO。
在一种实施方式中,若每个SSB映射的RO数量为1,每个RO映射的SSB数量为N,N大于或等于1,则X等于M;
根据SSB与RO之间的映射关系以及X个SSB,确定RO组合,包括:
根据SSB与RO之间的映射关系,确定X个SSB对应的K个RO,若K等于M,则将K个RO确定为M个RO。
在一种实施方式中,还包括:
若K小于M,则继续选择除X个SSB之外的其他SSB对应的RO,直至确定出M个RO,或者,若K小于M,则从K个RO之后再选择连续的M-K个RO,以得到M个RO。
本实施例中,网络设备先确定由X个SSB构成的SSB组合,再基于每个SSB组合来确定RO组合,其中,基于X个SSB确定M个RO的方法与终端侧类似,区别在于网络设备侧不基于SSB的SS-RSRP来选择SSB。即,网络设备侧不是基于SSB的SS-RSRP确定唯一的一种SSB组合,而是确定出可能的一种或多种SSB组合,针对每种SSB组合,确定一种或多种RO组合。在基于X个SSB确定M个RO时,也不基于SSB的SS-RSRP来选择SSB对应的RO,而是选择可能的一种或多种M个RO。
在一种实施方式中,网络设备向终端发送RO的个数M,M用于指示在M个RO发送前导序列。
在一种实施方式中,网络设备向终端发送SSB的个数X,X用于指示基于X个SSB确定用于发送前导序列的M个RO。
在一种实施方式中,网络设备向终端发送附加比特的分段数L,L为大于1的整数,L用于指示每个前导序列承载附加比特的1/L。
在一种实施方式中,L是根据M计算得到的,或者,M是根据L计算得到的。
网络设备向终端发送的上述信息的作用在前述实施例中已经详细进行了介绍,此处不再赘述。
网络设备通过接收终端通过M个RO发送的前导序列,提升了前导序列性能。
