Description
交叉引用
本发明要求在2022年04月02日提交中国专利局、申请号为202210346938.3、发明名称为“随机接入资源配置方法、装置、终端及网络侧设备”的中国专利申请的优先权,该申请的全部内容通过引用结合在本发明中。
本申请属于移动通信技术领域,具体涉及一种随机接入资源配置方法、装置、终端及网络侧设备。
新空口(New Radio,NR)***中的随机接入(Random Access)过程中上行信号,例如4步随机接入(4-step Radom Access Channel,4-step RACH)过程的消息1(Msg1)的覆盖性能相对于其他信道的覆盖性能较差,为此,需要引入物理随机接入信道(Physical Random Access Channel,PRACH)的Msg1重复传输来提升Msg1的覆盖性能。
同步信号块(Synchronization Signal Block,SSB)和随机接入时机(RACH Occasion,RO)的关联周期(Association Period)的可选值可以为10ms,20ms,40ms,80ms和160ms。对应的随机接入响应(Random Access Response,RAR)监听窗口长度最大为10ms。因此,关联周期的时间长度可能会长于RAR监听窗口的时间长度。在这种情况下如果仍然使用多个关联周期中的RO来实现Msg1重复传输,那么每次传输Msg1的时间间隔都将大于RAR监听窗口。如果只使用现有的PRACH资源进行Msg1重复传输,Msg1传输时间间隔过长,相当于反复尝试执行多次Msg1单次传输,导致终端接入流程时延增长;传输间隔太长也导致Msg1重复传输的分集增益受到影响;Msg1传输时根据SSB的参考信号接收功率(Reference Signal Received Power,RSRP)选择合适下行参考波束,时间间隔过长导致下行参数波束有效性过期。
现有的RO资源不支持进行多次的随机接入信号重复传输,无法有效提升重复传输带来的分集增益。

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随机接入资源配置方法、装置、终端及网络侧设备进行详细地说明。
如图2所示,本申请实施例提供了一种随机接入资源配置方法,该方法的执行主体为终端,换言之,该方法可以由安装在终端的软件或硬件来执行。所述方法包括以下步骤。
S210、终端从网络侧设备接收第一配置信息,所述第一配置信息用于配置随机接入信号重复传输的第一RO资源集合和/或第二RO资源集合。
其中,所述第一RO资源集合包括以下至少一种RO资源:
4-step RACH的RO资源;
2步随机接入(2-step RACH)的RO资源;
消息3(Msg3)重复传输(for requesting Msg3repetition)的4-step RACH的RO资源。
应理解的是,所述随机接入信号重复传输可以为4-step RACH的Msg1的重复传输,所述第一RO资源信息和第二RO资源集合中包括可以用于执行4-step RACH的Msg1的重复传输的RO资源。
应理解的是,所述随机接入信号重复传输的RO资源可以与4-step RACH的RO资源、2-step RACH的RO资源或Msg3重复传输的RO资源中的至少
之一进行复用。所述第一RO资源集合可以为对上述至少一种RO资源所对应的preamble资源集合进行划分得到的,例如,在终端支持4-step RACH,且配置有4-step RACH的RO资源情况下,所述第一RO资源集合可以包括4-step RACH的RO资源,所述第一RO资源集合中作为第一RO资源的4-step RACH的RO资源对应的preamble可用于随机接入信号的重复传输,即用于Msg1的重复传输;在终端支持2step-RACH,且配置了2-step RACH的RO资源的情况下,所述第一RO资源集合还可以包括2-step RACH的RO资源,第一RO资源集合中作为第一RO资源的2-step RACH的RO资源对应的preamble资源可用于随机接入信号的重复传输,即用于Msg1重复传输;在终端支持Msg3重复传输,且配置了Msg3重复传输的RO资源的情况下,所述第一RO资源集合还可以包括Msg3重复传输的RO资源,所述第一RO资源集合中作为第一RO资源的Msg3重复传输的RO资源对应的preamble资源可用于随机接入信号的重复传输,即用于Msg1重复传输。
网络侧设备也可以分别为每种RO资源分别配置对应的第一RO资源集合。
在一种实施方式中,所述网络侧设备可以为终端配置包括4-step RACH的RO资源的第一RO资源集合和/或包括专用RO资源的第二RO资源集合。
在另一种实施方式中,所述网络侧设备可以为所述终端配置包括2-step RACH的RO资源的第一RO资源集合和/或包括专用RO资源第二RO资源集合。
在另一种实施方式中,所述网络侧设备可以为所述终端配置包括Msg3重复传输的RO资源的第一RO资源集合和/或包括专用RO资源的第二RO资源集合。
在另一种实施方式中,所述网络侧设备可以为所述终端同时配置包括4-step RACH的RO资源和Msg3重复传输的RO资源的第一RO资源集合和/或包括专用RO资源的第二RO资源集合。
如图3,可选地,所述网络侧设备在4-step RACH的RO资源、2-step RACH的RO资源和Msg3重复传输的RO资源的集合中划分用于Msg1重复传输的第一RO资源集合,并且为每种第一RO资源配置对应的重复次数N0、N1和N2,所述N0、N1和N2可以是相同的,也可以是不同的。
但为了简便起见,在下面的实施例中均以所述网络侧设备为所述终端配置包括4-step RACH的RO资源的第一RO资源集合和/或包括专用RO资源
的第二RO资源集合为例进行举例说明。
所述第二RO资源集合包括用于仅用于随机接入信号重复传输的专用RO资源。
应理解的是,网络侧设备向终端发送的第一配置信息可以基于实际的需求包括第一消息和/或第二消息,其中,所述第一消息用于为所述终端配置第一RO资源集合,而第二消息用于为所述终端配置第二RO资源集合。
S220、所述终端确定所述第一RO资源集合和/或第二RO资源集合中的RO资源的关联关系。
进一步,步骤S220包括确定以下至少一种关联关系:
所述第一RO资源集合中的RO资源之间的关联关系;
所述第二RO资源集合中的RO资源之间的关联关系;
所述第一RO资源集合与所述第二RO资源集合中的RO资源之间的关联关系。
应理解的是,所述关联关系的确定方式可以存在多种实现方式,可以根据预定义的映射规则(mapping criteria)也可以称为关联规则(association criteria)来确定,或者通过关联标识信息来确定。所述关联关系可用于表示存在关联的RO资源,也可以表示存在关联关系的RO资源的关联信息,例如用于同一次的Msg1重复传输,对应于相同的重复次数,或者对应于相同的SSB或SSB集合等。
S230、所述终端根据所述第一RO资源集合和/或第二RO资源集合中的RO资源的关联关系确定N个RO资源来执行N次随机接入信号重复传输,所述N为正整数。
所述终端可以从存在关联的第一RO资源和/或第二RO资源中确定出符合本次随机接入信号重复传输的N个RO资源来执行N次随机接入信号重复传输。
所述N次随机接入信号重复传输为在N个RO资源中分别执行随机接入信号传输。例如,可以为在N个第一RO资源(4-step RACH RO资源)中分别传输携带Msg1重复传输对应的preamble的Msg1。
应理解的是,若所述网络侧设备为终端仅配置了第一RO资源集合,则终端执行的N次随机接入信号重复传输均在第一RO资源上;若所述网络侧设备为终端仅配置了第二RO资源集合,则终端执行的N次随机接入信号重复传输均在第二RO资源上;若所述网络侧设备为终端配置了第一RO资源
集合和第二RO资源集合,则终端执行的N次随机接入信号重复传输中,可以有N1次在第一RO资源上,以及N2次在第二RO资源上,N1+N2=N,其中N1,N2为大于等于0的整数。
由上述实施例的技术方案可知,本申请实施例提供的随机接入资源配置方法通过网络侧设备接收第一配置信息,所述第一配置信息用于配置随机接入信号重复传输的第一RO资源集合和/或第二RO资源集合,其中,所述第一RO资源集合可以包括4-step RACH的RO资源,2-step RACH的RO资源或Msg3重复传输的4-step RACH的RO资源,所述第二RO资源集合包括专用RO资源;再确定所述第一RO资源集合和/或第二RO资源集合中的RO资源的关联关系;然后根据所述第一RO资源集合和/或第二RO资源集合中的RO资源的关联关系确定N个RO资源来执行N次随机接入信号重复传输,从而可以支持更大重复次数的随机接入信号重复传输,在更短的时间内完成随机接入信号重复传输,获取更好的分集增益,并且通过不同的RO资源的组合,使得***可以高效得利用RO资源。
基于上述实施例,进一步地,以网络侧设备为终端配置了第一RO资源集合和第二RO资源集合为具体实施方式进行举例说明,如图4所示,步骤S210包括:
S211、所述终端从所述网络侧设备接收第一消息,所述第一消息用于为所述终端配置用于随机接入信号重复传输的第一RO资源集合。
在一种实施方式中,所述第一消息可以承载于无线资源控制(Radio Re source Control,RRC)消息中,例如***信息块(System Information Block,SIB)1、随机接收信道的配置消息RACHconfigcommon。
在一种实施方式中,所述第一消息包括以下至少一项:
与所述第一RO资源集合中的第一RO资源对应的第一前导码(preamble)资源集合,所述第一preamble资源集合包括用于随机接入信号重复传输的第一preamble资源;
与所述第一RO资源对应的重复次数M1;
与所述第一RO资源对应的第一标识信息。
应理解的是,所述第一RO资源集合中的第一RO资源可以为4-step RACH的RO资源、2-step RACH的RO资源、或Msg3重复传输的4-step RACH的RO资源中的至少之一。所述第一RO资源集合可以为上述任一RO资源的中部分或全部RO资源,即所述第一RO资源集合可以包括全部或部分的
4-step RACH的RO资源,全部或部分的2-step RACH的RO资源,或者全部或部分的Msg3重复传输的4-step RACH的RO资源中的至少之一。
应理解的是,为所述第一RO资源配置的第一preamble资源集合包括对应RO资源的preamble资源中用于随机接入信号重复传输的preamble资源。例如,若所述第一RO资源为4-step RACH的RO资源,则该第一RO资源的第一preamble资源集合包括该4-step RACH的RO资源对应的所有preamble资源中可用于随机接入信号重复传输的preamble资源。
在一种实施方式中,不同的重复次数对应于互相不重叠的第一preamble资源集合。
应理解的是,所述第一RO资源对应的重复次数M1,用于表示所述第一RO资源可用于M1次随机接入信号重复传输,所述M1可根据实际的需要进行设定,例如2次、4次等,为了简便起见,在下面的实施例中均以2次随机接入信号重复传输和4次随机接入信号重复传输为例进行举例说明。
应理解的是,每个第一RO资源可以仅对应一个重复次数,也可以同时对应多个重复次数。
应理解的是,所述与第一RO资源对应的第一标识信息可以是为每个第一RO资源分别配置的第一标识信息,也可以仅为所述第一RO资源集合配置一个统一的标识信息,所述统一的标识信息包括根据第一RO资源集合中第一RO资源的编号确定的与所述第一RO资源对应的第一标识信息,例如,若所述第一RO资源集合配置的标识信息为掩码(Mask)信息,通过不同的掩码来指示不同的RO资源子集,例如,Mask0定义为偶数编号的第一RO资源,即为偶数编号的第一RO资源对应的第一标识信息,Mask1定义为奇数编号的第一RO资源,即为奇数编号的第一RO资源对应的第一标识信息。
在一种实施方式中,所述第一标识信息可用于指示与所述第一RO资源对应的重复次数,例如,如图5所示,所述第一RO资源集合中包括与SSBi对应的8个第一RO资源RO0、RO1、RO2、RO3、RO4、RO5、RO6和RO7,根据网络侧设备配置的Mask,Mask0指示偶数编号的第一RO资源RO0、RO2、RO4和RO6,用于重复2次的随机接入信号重复传输,Mask1指示奇数编号的第一RO资源,RO1、RO3、RO5、RO7,用于重复4次的随机接入信号重复传输。
在一种实施方式中,所述与所述第一RO资源对应的第一preamble资源集合由以下至少一项确定:
所述第一preamble资源集合中第一preamble资源的数量;
所述第一preamble资源集合中第一preamble资源的起始编号(preamble index);
与所述第一RO资源集合对应的第一preamble资源的总数。
在一种实施方式中,可以根据所述第一消息中配置的所述第一RO资源对应的重复次数、所述第一RO资源对应的第一preamble资源集合中第一preamble资源的数量、所述第一preamble资源集合中第一preamble资源的起始编号和第一标识信息,来确定所述与所述重复次数对应的第一preamble资源集合。其中,所述第一preamble资源的起始编号除了第一个第一preamble资源集合中必须配置外可以缺省,所述第一标识信息也可以缺省。
在另一种实施方式中,可以根据所述第一消息中配置的所述第一RO资源对应的重复次数、所述第一RO资源对应的第一preamble资源集合中第一preamble资源的数量、所述第一preamble资源集合中第一preamble资源的起始编号。其中,所述第一preamble资源的起始编号除了第一个第一preamble资源集合中必须配置外可以缺省,所述第二个第一preamble资源集合的起始编号为所述第一个第一preamble资源集合的结束编号的下一个编号,并以此类推。
在另一种实施方式中,若所述第一消息中配置了与所述第一RO资源集合对应的第一preamble资源的总数,则对于最后一个第一preamble资源集合,其对应的第一preamble资源的数量可以缺省,隐式的根据第一preamble资源的总数与其它第一preamble资源集合中第一preamble资源的数量来确定。
应理解的是,所述第一消息还可以包括所述第一RO资源集合中的第一RO资源的时域信息,所述第一RO资源的频域信息,以及所述第一RO资源与SSB的关联信息。
S212、所述终端从所述网络侧设备接收第二消息,所述第二消息用于为所述终端配置用于随机接入信号重复传输的第二RO资源集合。
在一种实施方式中,所述第二消息可以由RRC消息承载,例如SIB1、RACHconfigcommon等。
在一种实施方式中,所述第二消息包括以下至少一项:
所述第二RO资源集合中的第二RO资源的时域信息;
所述第二RO资源的频域信息;
所述第二RO资源与SSB的关联信息;
与所述第二RO资源对应的第二preamble资源集合,所述第二preamble资源集合包括用于随机接入信号重复传输的第二preamble资源。
在一种实施方式中,所述第二RO资源的频域信息包括以下至少一项:
频域起始位置;
频域复用数。
在一种实施方式中,在所述第二消息不包括所述第二RO资源的频域信息的情况下,第二消息没有显示配置所述第二RO资源的频域信息,则所述第二RO资源的频域信息复用所述第一RO资源的频域信息,例如,复用4-step RACH的RO资源的频域起始位置和频域复用数。具体的复用规则由协议预定义或者在RRC消息中指示。
在一种实施方式中,所述第二RO资源与SSB的关联信息包括:
SSB到所述第二RO资源的关联关系参数(ssb-perRACH-Occasion);
与所述第二RO资源对应SSB集合。
应理解的是,所述关联有关系参数为用于指示一个SSB关联多个第二RO资源的配置参数。在一种实施方式中,在所述第二消息不包括所述SSB到所述第二RO资源的关联关系参数的情况下,所述SSB到所述第二RO资源的关联关系参数复用所述SSB到所述第一RO资源的关联关系参数,例如复用4-step RACH的RO资源的SSB到RO资源的关联的配置参数。在一种实施方式中,所述SSB到第二RO资源的关联关系参数的取值可以进行重新定义,仅配置一个SSB到第二RO资源的关联情况,例如配置候选取值集合,包括1、1/2、1/4、1/8、1/16等等。
在一种实施方式中,所述第二RO资源对应的SSB集合可以是与随机接入信号传输的RO资源关联的SSB集合的子集,可以通过每个第二RO资源对应的SSB有效信息来指示与随机接入信号传输的RO资源关联的SSB集合中的一个SSB子集与所述第二RO资源相对应。所述SSB子集的划分方式可以通过指示信息指示或者数组枚举或者通过预定义协议将所述第一RO资源关联的SSB集合划分为多个SSB子集。例如,一个小区发送R个SSB:SSB0~SSBR-1,配置了两个第二RO资源用于随机接入信号重复传输:专用RO资源1和专用RO资源2。专用RO资源1用于SSB子集1{SSB0~SSBR/2}的随机接入信号重复传输,专用RO资源2用于SSB子集2{SSBR/2+1~SSBR-1}的随机接入信号重复传输。专用RO资源1使用SSB子集1进行SSB到第二RO资源的关联操作;专用RO资源2使用SSB子集
2进行SSB到第二RO的关联操作。
在一种实施方式中,所述第二消息还可以包括:与所述第二RO资源对应的重复次数,例如配置的第二RO资源集合中包括两个第二RO资源用于重复传输,专用RO资源1和专用RO资源2,并且专用RO资源1用于2次重复传输,专用RO资源2用于4次重复传输。
在一种实施方式中,所述第二消息还可以包括:与所述第二RO资源对应的第二标识信息。
在一种实施方式中,所述第二标识信息用于指示以下至少一项:
与所述第二RO资源对应的重复次数;
与所述第二RO资源关联的SSB或SSB集合。
在一种实施方式中,在所述网络侧设备为所述终端配置第一RO资源集合和第二RO资源集合的情况下,步骤S220包括:
S221、确定所述第一RO资源集合与所述第二RO资源集合中的RO资源之间的关联关系。
在一种实施方式中,步骤S221包括:
根据第一条件,确定第一RO资源集合中X个第一RO资源,以及第二RO资源集合中的Y个第二RO资源;其中,所述X和Y为正整数。
所述第一条件可以包括以下至少一项:
所述第一RO资源与第一SSB相对应,且所述第二RO资源与第二SSB相对应;
所述第一RO资源与所述第二RO资源对应相同的重复次数。
在一种实施方式中,所述第一SSB和第二SSB可以是相同的SSB,所述随机接入信号重复传输应用于单一的SSB,则需要确定该单一的SSB对应的第一RO资源与第二RO资源之间的关联关系。
在另一种实施方式中,所述第一SSB和第二SSB可以相同的一组SSB,所述随机接入信号重复传输可应用于一个SSB子集,则需要确定与该一个SSB子集对应的第一RO资源与第二RO资源之间的关联关系。
在另一种实施方式中,所述第一SSB和第二SSB也可以是不同的或不同的,所述随机接入信号重复传输在第一RO资源上的随机接入信号重复传输关联于第一SSB,所述随机接入信号重复传输在第二RO资源上的随机接入信号重复传输关联于第二SSB,则需要分别确定与第一SSB对应的第一RO资源与第二SSB对应的第二RO资源之间的关联关系。
为了简便起见,在下面的实施例中均以所述第一SSB和第二SSB为同一SSB为例进行举例说明。
在确定所述X个第一RO资源和Y个第二RO资源之后,确定所述X个第一RO资源与所述Y个第二RO资源的关联关系。具体地,所述X个第一RO资源是所述第一RO资源集合中第一RO资源与SSB的一个关联循环(association cycle)内的,并且与第一SSB关联的第一RO资源。所述X个第二RO资源是所述第二RO资源集合中第二RO资源与SSB的一个关联循环(association cycle)内的,并且与第二SSB关联的第二RO资源;或者所述X个第二RO资源是所述第二RO资源集合中第二RO资源与SSB的一个关联循环(association cycle)内的,在一个RO时间资源内的,与第二SSB关联的第二RO资源。进一步可选地,确定X个用于N次随机接入信号重复传输的第一RO资源和Y个用于N次随机接入信号重复传输的第二RO资源,即,从支持N次随机接入信号重复传输的第一RO资源集合中选择X个第一RO资源,和支持N次随机接入信号重复传输的第二RO资源集合中选择Y个第二RO资源。
该关联关系的确定方式可以多种实现方式,在一种实施方式中,所述X个第一RO资源与所述Y个第二RO资源的关联关系由以下至少一种方式确定:
根据预定义的映射规则确定;
根据第一映射信息确定,所述第一映射信息承载于所述第一配置信息中。
在一种实施方式中,所述预定义的映射规则可以与所述第一RO资源的频域复用数和所述第二RO资源的频域复用数的对应关系相关。
第二RO资源的频域复用数可能小于第一RO资源的频域复用数。多个第一RO资源需要与一个第二RO资源建立关联关系。考虑到需要执行随机接入信号重复发送的终端占小区内终端总数的比例较小,在碰撞概率近似相同的前提下,第二RO资源所需的频率资源相对较小,从而提高第二RO资源的利用效率。
在一种实施方式中,可以按照均匀映射的原则将X个第一RO资源与Y个第二RO资源进行关联,所述每个第二RO资源关联于或者个第一RO资源,或者每个第一RO资源关联于或者个第二RO资源。其中,为下取整符号,为上取整符号。具体的映射方式可以是按照分组的方式将X个第一RO资源划分为Y组,分别关联于Y个第二RO资源;
或者,按照循环映射的方式按照RO编号顺序循环的映射到Y个第二RO资源上。如图6所示,确定与SSBi对应的8个第一RO资源RO0~RO7,以及与SSBi对应的2个第二RO资源RO8和RO9,则按照均匀分布的原则,将RO0~RO3关联于RO8,RO4~RO7关联于RO9。
在一种实施方式中,步骤S221还包括:
确定所述第一RO资源集合中第一RO资源对应的第一preamble资源集合与所述第二RO资源集合中第二RO资源对应的第二preamble资源集合之间的关联关系;
其中,所述第一preamble资源集合包括所述第一RO资源上用于随机接入信号重复传输的preamble资源;所述第二preamble资源集合包括所述第二RO资源上用于随机接入信号重复传输的preamble资源。
确定所述第一preamble资源集合和第二preamble资源集合的关联关系的方式可以存在多种实现方式,本申请实施例仅给出了其中的一种具体实施方式,由以下方式确定:
根据第二preamble资源的第二编号顺序和第一preamble资源的第一编号顺序,从目标第二preamble资源开始,依次将所述第二preamble资源与第一preamble资源进行关联;
其中,所述第二编号顺序基于所述第二preamble资源集合中的第二preamble资源的编号确定,所述第一编号顺序基于所述关联的第一RO资源的RO编号大小和所述第一preamble资源集合中的第一preamble资源的preamble编号大小确定。
根据第一RO资源的RO编号由低到高,以及对应的第一preamble资源集合中的第一preamble资源的preamble编号由低到高,映射到第二RO资源对应的第二preamble资源集合中第二preamble资源上。如图6所示,若每个第一RO资源对应的第一preamble资源集合中包括n个第一preamble资源,则可以将RO0~RO3对应的第一preamble资源集合中的第一preamble资源排序得到的第一编号顺序preamble编号0~4n-1,并与RO8对应的第二preamble资源集合中的第二preamble资源建立硫交联关系。
应理解的是,所述目标第二preamble资源为所述第二preamble资源集合中的首个第二preamble资源,默认为编号为0的第二preamble资源。
在一种实施方式中,还可以基于第一配置信息中携带的第一映射信息来显示指示所述X个第一RO资源与所述Y个第二RO资源的关联关系。例如,
所述第一映射信息可以为与第一RO资源对应的第一标识信息,以及与第二RO资源对应的第二标识信息,则可以基于第一标识信息和第二标识信息,例如,将第一标识信息和第二标识信息相对应的第一RO资源和第二RO资源进行关联。
在一种实施方式中,所述第一映射信息用于指示以下至少一项:
所述第一SSB和所述第二SSB的关联信息,例如可以为同一SSB,相同的SSB子集,不同SSB组合等;
所述X个第一RO资源与所述Y个第二RO资源的关联关系;
所述目标第二preamble资源。
在另一种实施方式中,所述预定义的映射规则可以与所述第一RO资源的时域位置通过时域放大或延展后与所述第二RO资源的时域位置的对应关系相关。即确定第二RO资源的时域占用资源是第一RO资源的时域占用资源的S倍,具体的配置方式可以基于第一RO资源的时域的资源配置参数,额外配置时隙偏移量或者RO资源周期的缩放系数来获得S倍速的第二RO资源。
在一种实施方式中,第一RO资源与第二RO资源为1对S的关联关系,在第一RO资源的配置周期内包含S倍的第二RO资源。
在一种实施方式中,第一RO资源与第二RO资源的时域连续S个第二RO资源关联。所述时域连续S个第二RO资源所关联的SSB与所述第一RO资源保持一致。
第一RO资源的SSB到第二RO资源关联图案在第二RO资源上重复S次。终端选择第二RO资源的关联图案中与第一RO资源的位置相同的RO资源作为第一RO资源关联的S个第二RO资源。
第二RO资源对应第二preamble集合与第一RO资源的随机接入信号重复传输的第一preamble集合一一对应。具有相同的preamble index。
应理解的是,第二RO资源与第一RO资源的关联过程中,可以额外第二配置映射信息,所述第二配置映射信息可以与时域相关,用于指示第一RO资源中一个时域RO子集与第二RO资源关联。
应理解的是,所述第一RO资源集合中的RO资源之间的关联关系的确定方式可以存在多种实现方式,可以根据预定义的映射规则确定,或者通过关联标识信息来确定。确定所述第一关联循环中述X个RO资源和所述第二关联循环中X个RO资源,所述第一关联循环和第二关联循环是所述第一RO
资源集合中不同时间的关联循环;所述第一关联循环中述X个RO资源和所述第二关联循环中X个RO资源关联于相同SSB;根据预定义的映射规则,相同编号的RO资源建立映射关系;或者,关联标识信息,例如RO编号偏移量,确定第一关联循环中述X个RO资源和所述第二关联循环中X个RO资源的映射关系;第一关联循环中述X个RO资源和所述第二关联循环中X个RO资源中相同preamble建立映射关系。
应理解的是,所述第一RO资源集合中的RO资源之间的关联关系的确定方式可以存在多种实现方式,可以根据预定义的映射规则或者通过关联标识信息来确定。确定所述第三关联循环中述Y个RO资源和所述第四关联循环中Y个RO资源,所述第三关联循环和第四关联循环是所述第二RO资源集合中不同时间的关联循环;或者确定所述第一RO时间资源中述Y个RO资源和所述第二RO时间资源中Y个RO资源,所述第一RO时间资源和第二RO时间资源是所述第二RO资源集合中不同时间的RO时间资源;所述第三关联循环中Y个RO资源和所述第四关联循环中Y个RO资源关联于相同SSB;根据预定义的映射规则,相同编号的RO资源建立映射关系;或者,关联标识信息,例如RO编号偏移量,确定第三关联循环中述Y个RO资源和所述第四关联循环中Y个RO资源的映射关系;第三关联循环中述Y个RO资源和所述第四关联循环中Y个RO资源中相同preamble建立映射关系。
在一种实施方式中,步骤S220还可以包括:
确定所述第一RO资源集合中的RO资源之间的关联关系,具体可以由以下至少一项确定:
所述RO资源对应的第一标识信息;
所述RO资源对应的复用次数;
所述RO资源对应SSB。
例如,可以将对应于相同的SSB且具有相同复用次数的第一RO资源进行关联。
在一种实施方式中,步骤S220还可以包括:
确定所述第二RO资源集合中的RO资源之间的关联关系,具体可以由以下至少一项确定:
所述RO资源对应的第二标识信息;
所述RO资源对应的复用次数;
所述RO资源对应的SSB。
例如,可以将对应于相同的SSB且具有相同的复用次数的第二RO资源进关联。
在一种实施方式中,在步骤S230之前,所述方法还包括:
在满足第一条件的情况下,所述终端确定执行随机接入信号重复传输;
其中,所述第一条件包括以下至少一项:
所述第三SSB的信号质量低于第一阈值T0,所述第三SSB为用于进行随机接入信号重复传输的SSB;
执行随机接入流程的失败次数达到第二阈值。
应理解的是,所述第三SSB可以是终端根据各SSB的信号质量选择的SSB。
所述终端可以检测第三SSB的信号质量,例如,下行路损参考或者RSRP,在所述第三SSB的信号质量低于第一阈值T0时,终端确定执行随机接入信号重复传输。或者,终端在执行随机接入信号传输并且失败M次后,终端确定执行随机接入信号重复传输,其中,可以将进行随机接入信号传输后没有收到Msg2消息送为随机接入信号传输失败。
在一种实施方式中,步骤S230包括:
S231、所述终端根据所述第三SSB的信号质量,确定重复次数。
在一种实施方式中,终端可以设置有A-1个第一阈值T1,以得到A个阈值区间,根据SSB信号质量所在的阈值区间分别对应于A种重复次数。将各SSB的信号质量,例如RSRP,依次与A-1个第一阈值T1进行比较。选择超过第一阈值T1的SSB作为第三SSB或者选择信号质量最好的SSB作为第三SSB,并将超过第一阈值T1所在的阈值区间对应的重复次数作为本次随机接入信号重复传输的重复次数。如果有多个SSB满足上述条件,则可以随机选择其中一个SSB作为第三SSB;如果没有SSB的信号质量超过任意第一阈值T1,那么使用网络配置的最大重复次数进行随机接入信号重复传输。或者,从网络配置的若干个SSB组合中选择一个SSB组合作为第三SSB,SSB组合中至少有一个SSB的信号质量超过所述第一阈值T1。
S232、根据所述第三SSB和随机接入信号重复次数,以及所述第一RO资源集合和/或第二RO资源集合的关联关系,确定N个RO资源。
从第一RO资源集合和/或第二RO资源集合中确定用于执行本次随机接入信号重复传输的第一RO资源和/或第二RO资源,以及对应的第一preamble资源集合和/或第二preamble资源集合。
S233、通过所述N个RO资源执行N次随机接入信号重复传输。
在一种实施方式中,随机接入信号重复传输可以在一个或者多个时间单元内完成,所述时间单元可以是4-step RACH相关的SSB到RO的关联循环时间(association cycle)或者关联周期(association period)或者关联模式周期(association pattern period)。例如一个PRACH关联周期内包含a个SSB到第一RO资源的映射循环(association cycle),以及b个SSB到第二RO资源的映射循环,那么一个PRACH关联周期内可以支持小于等于a+b个随机接入信号重复传输。若随机接入信号重复发送次数为c,那么随机接入信号重复传输占用的连续的PRACH关联周期为c/(a+b)。其中,多个连续的PRACH关联周期的第一个关联周期从协议定义的参考关联周期开始计算,例如以无线帧0为开始的PRACH关联周期来划分用于随机接入信号重复传输的连续PRACH关联周期。
终端以所述时间单元内的第一个满足第一条件的RO资源为起始RO开始执行随机接入信号重复传输。所述第一条件可以是所述时间单元内第一个与第三SSB关联的支持N次随机接入信号重复传输的第一RO资源;或者所述时间单元内第一个与第三SSB关联的支持N次随机接入信号重复传输的第一RO资源或者第二RO资源。
可以理解,N次随机接入信号重复传输使用preamble由第一RO资源与第二RO资源的关联关系确定。
在一种实施方式中,随机接入信号重复传输的时间跨度不应超过预设的时间上限,所述时间上限可以PRACH association cycle,或者PRACH association period,或者PRACH关联模式周期(association pattern period)。***可以根据所述时间上限对应的时间范围存在的第一RO资源和第二RO资源的数量来确定支持的最大随机接入信号重复传输次数。
终端在发送随机接入信号重复传输之后,需要监听开启RAR监听窗口,监听从网络侧设备发送的RAR。所述RAR监听窗口的开启方式可以存在多种实现方式,本申请实施例仅给出了其中的几中具体实施方式进行举例说明。
在一种实施方式中,终端可以在每次随机接入信号传输之后开启RAR监听窗口,监听窗口的长度可以由RRC消息配置。如果监听窗口没有收到RAR并且随机接入信号重复传输的次数没有达到重复次数,则在下一个确定的第一RO资源或第二RO资源上再次发送随机接入信号;如果发送的随机接入信号重复传输的次数达到到重复次数,则可认为本次随机接入信号重复传输
失败,随机接入信号传输的失败计数器加一,并且执行自动回退(backoff)。
在另一种实施方式中,终端可以在完成N次随机接入信号重复传输之后再开启RAR监听窗口,如果监听窗口没有收到RAR,则直接认为本次随机接入信号重复传输失败,随机接入信号传输的失败计数器加一,并且执行自动回退(backoff)。
由上述实施例中的技术方案可知,本申请实施例通过在网络侧设备为终端配置了第一RO资源集合和第二RO资源集合的情况下,终端根据第一条件,确定第一RO资源集合中X个第一RO资源,以及第二RO资源集合中的Y个第二RO资源;再确定所述X个第一RO资源与所述Y个第二RO资源的关联关系,从而可以支持更大重复次数的随机接入信号重复传输,获取更好的分集增益,并且通过不同的RO资源的组合,使得***可以高效得利用RO资源。
基于上述实施例,进一步地,如图6所示,所述第二RO资源集合位于单独配置的带宽部分(BandWidth Part,BWP)。
应理解的是,所述单独配置的BWP,为上行BWP(Uplink BWP,UL BWP),仅用于配置第二RO资源集合,即网络侧设备为所述终端仅配置了第二RO资源集合,因此,不存在确定第一RO资源集合和第二RO资源集合中RO资源的关联关系。
终端通过检测第三SSB的信道质量判断是否执行随机接入信号重复传输,即在所述第三SSB的信道质量低于第一阈值T0时,执行随机接入信号重复传输。如果终端执行随机接入信号重复传输,则将所述终端切换到该单独配置的UL BWP上,否则,在随机接入信号传输的常规的UL BWP上。
终端需要确定所述第二RO资源集合中的RO资源之间的关联关系,具体可以由以下至少一项确定:
所述RO资源对应的第二标识信息;
所述RO资源对应的复用次数;
所述RO资源对应的SSB。
在一种实施方式中,网络侧设备配置RO资源的频域复用数F和SSB到第二RO资源的关联关系参数L,并且L=k*F。这使得时域上连续k个第二RO资源关联于同一个SSB。终端可以利用所述第二RO资源,实现不超过k次的随机接入信号重复传输。
由上述实施例中的技术方案可知,本申请实施例通过网络侧设备为终端
配置位于单独配置的BWP上的第二RO资源集合,用于进行随机接入信号重复传输,从而可以支持更大重复次数的随机接入信号重复传输,获取更好的分集增益。
