针对4步CFRA的情况,在触发4步CFRA后,终端需要在随机接入时机,也可以称作物理随机接入信道时机(PRACH occasion,RO)发起4步CFRA,因此,终端首先需要确定4步CFRA的RO资源信息。
但是,在某些情况下,网络侧并没有在CFRA配置信息中指示RO资源,在这种情况下,终端可以使用4步CBRA配置信息中的RO资源。
然而,随机通信技术的发展,应用场景也随之拓展,为了适用不同场景的feature特性,针对不同的特性可以配置不同的CBRA配置信息,因此终端可以被配置多个CBRA配置信息,这会导致终端没有在CFRA配置信息中确定到RO资源信息时,难以确定使用哪个CBRA配置信息中的RO资源用于CFRA。
发明内容
有鉴于此,本公开的实施例提出了随机接入时机资源信息的确定方法、随机接入时机资源信息的指示方法、随机接入时机资源信息的确定装置、随机接入时机资源信息的指示装置、通信装置和计算机可读存储介质,以解决相关技术中的技术问题。
根据本公开实施例的第一方面,提出一种随机接入时机资源信息的确定方法,由终端执行,所述方法包括:触发4步非竞争随机接入CFRA;在CFRA的RO配置信息中没有为所述终端独立配置的随机接入时机RO资源信息时,根据指定版本的4 步竞争随机接入CBRA的随机接入时机RO资源信息,确定触发的4步CFRA的RO资源信息。

具体实施方式
下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的,而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式,除非上下文清楚地表示其他含义。还应当理解,本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解,尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息,但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如,在不脱离本公开实施例范围的情况下,第一信息也可以被称为第二信息,类似地,第二信息也可以被称为第一信息。取决于语境,如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
出于简洁和便于理解的目的,本文在表征大小关系时,所使用的术语为“大于”或“小于”、“高于”或“低于”。但对于本领域技术人员来说,可以理解:术语“大于”也涵盖了“大于等于”的含义,“小于”也涵盖了“小于等于”的含义;术语“高于”涵盖 了“高于等于”的含义,“低于”也涵盖了“低于等于”的含义。
终端在触发4步CFRA后,需要在随机接入时机RO(也可以称作物理随机接入信道时机)发起CFRA,因此,终端首先需要确定4步CFRA的RO资源信息。
一般情况下,4步CFRA的RO资源信息,在CFRA配置中包含两部分内容,一部分是RO配置信息,另一部分是同步信号块SSB(Synchronization Signal Block)和RO之间的对应关系,终端可以根据这两部分内容确定发起4步CFRA的RO。
但是,在某些情况下,网络侧并没有在CFRA配置信息中指示RO资源信息,例如在CFRA配置信息中RO配置信息缺省,在这种情况下,终端可以使用4步CBRA配置信息(通过信息元素RACH-ConfigCommon指示)中的RO资源。
然而,随机通信技术的发展,应用场景也随之拓展,例如在R17中,为了适用不同场景的feature特性,例如切片Slicing、小数据传输SDT(Small Data Transmission)、覆盖增强CE(Coverage Enhancement)、能力减持设备Redcap(Reduced Capability)等特性,针对不同的特性可以配置不同的CBRA配置信息,也即终端会被配置R17版本的4步CBRA的RO资源信息,其中,R17版本的4步CBRA的RO资源信息可以包括多个4步CBRA的RO资源信息。
并且终端还会被配置传统legacy版本的4步CBRA的RO资源信息,例如R15、R16版本的4步CBRA的RO资源信息。在legacy版本中,网络侧设备并不会针对上述特性分别为终端配置不同的CBRA配置信息,而只会为终端配置一个4步CBRA的RO资源信息。
那么对于终端而言,在被配置了legacy版本的4步CBRA的RO资源信息和R17版本的4步CBRA的RO资源信息的情况下,对于终端而言,就存在多个版本的4步CBRA的RO资源信息,面对多个版本的4步CBRA的RO资源信息时,终端会难以判断根据哪个版本的4步CBRA的RO资源信息确定4步CFRA的RO资源信息。本公开的以下实施例,主要是为了解决该技术问题而提出的。
图1是根据本公开的实施例示出的一种随机接入时机资源信息的确定方法的示意流程图。本实施例所示的随机接入时机资源信息的确定方法可以由终端执行,所述终端可以与网络侧设备通信,所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置,所述网络侧设备包括但不限于4G、5G、6G等通信系统中的网络侧设备,例如基站、核心网等。
如图1所示,所述随机接入时机资源信息的确定方法可以包括以下步骤:
在步骤S101中,触发4步非竞争随机接入CFRA;
在步骤S102中,在CFRA的RO配置信息中没有为所述终端独立配置的随机接入时机RO资源信息时,根据指定版本的4步竞争随机接入CBRA的随机接入时机RO资源信息,确定触发的4步CFRA的RO资源信息。
在一个实施例中,终端在某些情况下可以触发4步CFRA,其中,触发所述4步CFRA的方式包括以下至少之一:
物理下行控制信道命令PDCCH(Physical Downlink Control Channe)order触发;系统信息请求SI(System Information)request触发;切换Handover命令触发。
在触发4步CFRA后,终端需要确定4步CFRA的RO资源信息,例如在CFRA配置信息中确定是否有为所述终端独立配置的RO资源信息,如果有为所述终端独立配置的RO资源信息,那么终端可以根据为所述终端独立配置的RO资源信息确定发起4步CFRA的RO;如果没有为所述终端独立配置的RO资源信息,可以根据4步CBRA的RO资源信息,确定触发的4步CFRA的RO资源信息。
根据本公开的实施例,终端可以根据指定版本的4步CBRA的RO资源信息,确定触发的4步CFRA的RO资源信息。从而即使终端被配置了legacy版本的4步CBRA的RO资源信息和R17版本的4步CBRA的RO资源信息,也能够准确确定根据哪个版本的4步CBRA的RO资源信息,确定触发的4步CFRA的RO资源信息。避免了终端面对多个版本的4步CBRA的RO资源信息时,难以判断根据哪个版本的4步CBRA的RO资源信息确定4步CFRA的RO资源信息的技术问题。
需要说明的是,在相关技术(例如R15、R16)中,4步CBRA配置信息对应的信息元素为RACH-ConfigCommon,因此RACH-ConfigCommon默认是指legacy版本的4步CBRA配置信息。
根据本公开的实施例,为了明确指定版本具体是哪个版本,可以对信息元素RACH-ConfigCommon进行调整。
例如对于R17版本中的CBRA配置,可以通过不同的后缀区分于legacy版本中的CBRA配置,比如RACH-ConfigCommon-r17。
例如对于R17版本中的CBRA配置,可以通过不同的名称区分于legacy版本 中的CBRA配置,比如RACH-ConfigCommonExt-R17。
在一个实施例中,所述指定版本根据网络侧设备指示确定,或者根据协议约定确定。
终端可以根据网络侧设备指示确定所述指定版本,例如网络侧设备指示的指定版本为R17,那么终端根据R17版本的4步竞争随机接入CBRA的随机接入时机RO资源信息,确定触发的4步CFRA的RO资源信息;例如网络侧设备指示的指定版本为legacy版本,那么终端根据legacy版本的4步竞争随机接入CBRA的随机接入时机RO资源信息,确定触发的4步CFRA的RO资源信息。
终端也可以根据协议约定确定所述指定版本,例如协议约定的指定版本为R17,那么终端根据R17版本的4步竞争随机接入CBRA的随机接入时机RO资源信息,确定触发的4步CFRA的RO资源信息;例如协议约定的指定版本为legacy版本,那么终端根据legacy版本的4步竞争随机接入CBRA的随机接入时机RO资源信息,确定触发的4步CFRA的RO资源信息。
在一个实施例中,所述指定版本包括以下至少之一:传统legacy版本、R17版本。在一个实施例中,所述传统legacy版本包括以下至少之一:R15版本、R16版本。
图2是根据本公开的实施例示出的另一种随机接入时机资源信息的确定方法的示意流程图。如图2所示,所述根据指定版本的4步竞争随机接入CBRA的随机接入时机RO资源信息,确定触发的4步CFRA的RO资源信息包括:
在步骤S202中,将所述指定版本的4步CBRA的RO资源信息中的RO配置信息,确定为触发的4步CFRA的RO资源信息的RO配置信息。
在一个实施例中,触发4步CFRA的方式可以包括PDCCH order触发;系统信息请求SI request触发;切换Handover命令触发等。
4步CBRA的RO资源信息主要包括的RO配置信息以及SSB和RO之间的对应关系,也即终端需要确定的RO配置信息以及SSB和RO之间的对应关系。
对于上述三种触发方式而言,在触发方式为系统信息请求SI request触发或者切换Handover命令触发时,终端需要根据指定版本的4步竞争随机接入CBRA的随机接入时机RO资源信息,确定触发的4步CFRA的RO资源信息中的RO配置信息以及SSB和RO之间的对应关系;
而在触发方式为PDCCH order触发的情况下,由于在PDCCH中会指示SSB索引、PRACH mask索引等信息,终端基于这些信息可以确定SSB与RO之间的对应关系,所以终端只需要根据指定版本的4步竞争随机接入CBRA的随机接入时机RO资源信息,确定触发的4步CFRA的RO资源信息中的RO配置信息即可。
也即针对上述三种触发方式而言,终端都需要根据指定版本的4步竞争随机接入CBRA的随机接入时机RO资源信息,确定触发的4步CFRA的RO资源信息中的RO配置信息,例如可以将所述指定版本的4步CBRA的RO资源信息中的RO配置信息,确定为触发的4步CFRA的RO资源信息的RO配置信息;而在触发方式为系统信息请求SI request触发或者切换Handover命令触发时,终端还需要进一步确定触发的4步CFRA的RO资源信息中SSB和RO之间的对应关系,关于确定所述对应关系的内容,在后续实施例进行描述。
另外,在触发方式为PDCCH order触发的情况下,在本实施例中,网络侧设备可以不指示CFRA的RO资源信息中的RO配置信息,终端根据4步CBRA的RO资源信息中的RO配置信息,确定触发的4步CFRA的RO资源信息的RO配置信息;网络侧设备也可以通过PDCCH中的下行控制信息DCI(Downlink Control Information)指示CFRA的RO资源信息中的RO配置信息,终端根据DCI所指示的RO配置信息,确定触发的4步CFRA的RO资源信息的RO配置信息。

例如终端自身实现可以是仅根据legacy版本的4步CBRA的RO资源信息,确定触发的4步CFRA的RO资源信息中的RO配置信息。
图6是根据本公开的实施例示出的又一种随机接入时机资源信息的确定方法的示意流程图。如图6所示,触发所述4步CFRA的方式包括以下至少之一:系统信息请求SI request触发;切换Handover命令触发;所述方法还包括:
在步骤S601中,确定触发的4步CFRA的RO资源信息中SSB和RO之间的对应关系。
在一个实施例中,基于前述实施例可知,针对上述三种触发方式而言,终端都需要根据指定版本的4步竞争随机接入CBRA的随机接入时机RO资源信息,确定触发的4步CFRA的RO资源信息中的RO配置信息,例如可以将所述指定版本的4步CBRA的RO资源信息中的RO配置信息,确定为触发的4步CFRA的RO资源信息的RO配置信息;
而在触发方式为系统信息请求SI request触发或者切换Handover命令触发时,终端还需要进一步确定触发的4步CFRA的RO资源信息中SSB和RO之间的对应关系。进而终端才能根据RO配置信息和所述对应关系确定触发的4步CFRA所使用的RO。
在一个实施例中,所述确定触发的4步CFRA的RO资源信息中SSB和RO之 间的对应关系包括:
将所述指定版本的4步CBRA的RO资源信息中同步信号块SSB和RO之间的对应关系,确定为触发的4步CFRA的RO资源信息中SSB和RO之间的对应关系。
终端在基于前述实施例将所述指定版本的4步CBRA的RO资源信息中的RO配置信息,确定为触发的4步CFRA的RO资源信息的RO配置信息后,可以进一步将所述指定版本的4步CBRA的RO资源信息中同步信号块SSB和RO之间的对应关系,确定为触发的4步CFRA的RO资源信息中SSB和RO之间的对应关系。也即RO配置信息以及SSB和RO之间的对应关系,可以属于相同的RO资源信息。
在一个实施例中,所述确定触发的4步CFRA的RO资源信息中SSB和RO之间的对应关系包括:
根据网络侧设备预先配置(例如在系统消息中广播)给所述终端的所有版本的4步CBRA的RO资源信息中同步信号块SSB和RO之间的对应关系,确定触发的4步CFRA的RO资源信息中SSB和RO之间的对应关系。
终端在基于前述实施例将所述指定版本的4步CBRA的RO资源信息中的RO配置信息,确定为触发的4步CFRA的RO资源信息的RO配置信息后,可以根据网络侧设备预先配置给所述终端的所有版本的4步CBRA的RO资源信息(而不必局限在述指定版本的4步CBRA的RO资源信息)中同步信号块SSB和RO之间的对应关系,确定触发的4步CFRA的RO资源信息中SSB和RO之间的对应关系。
需要说明的是,当在网络侧设备预先配置给所述终端的所有版本的4步CBRA的RO资源信息中存在多个SSB和RO之间的对应关系时,终端可以在其中确定一个SSB和RO之间的对应关系,其中,SSB和RO之间的对应关系通过数值表征,例如1/8、1/4、1/2、1、2、4、8、16等,终端可以选择其中一个数值,例如选择其中最大值或最小值。
在一个实施例中,所述确定触发的4步CFRA的RO资源信息中SSB和RO之间的对应关系包括:
根据终端实现确定触发的4步CFRA的RO资源信息中SSB和RO之间的对应关系。
以下实施例从网络侧描述了在网络侧设备指示的情况下,终端如何确定触发的4步CFRA的RO资源信息。需要说明的是,网络侧设备指示,只是终端根据指定版 本的4步竞争随机接入CBRA的随机接入时机RO资源信息,确定触发的4步CFRA的RO资源信息的方式之一,终端也可以根据协议约定根据指定版本的4步竞争随机接入CBRA的随机接入时机RO资源信息,确定触发的4步CFRA的RO资源信息。
图7是根据本公开的实施例示出的一种随机接入时机资源信息的指示方法的示意流程图。本实施例所示的随机接入时机资源信息的指示方法可以由网络侧设备执行,所述网络侧设备可以与终端通信,所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置,所述网络侧设备包括但不限于4G、5G、6G等通信系统中的网络侧设备,例如基站、核心网等。
如图7所示,所述随机接入时机资源信息的指示方法可以包括以下步骤:
在步骤S701中,触发4步非竞争随机接入CFRA;
在步骤S702中,在终端的CFRA的RO配置信息中没有为所述终端独立配置的随机接入时机RO资源信息时,指示所述终端根据指定版本的4步竞争随机接入CBRA的随机接入时机RO资源信息,确定触发的4步CFRA的RO资源信息。
在一个实施例中,网络侧设备在某些情况下可以触发终端进行4步CFRA,其中,触发所述4步CFRA的方式包括以下至少之一:
物理下行控制信道命令PDCCH order触发;系统信息请求SI request触发;切换Handover命令触发。
网络侧设备在触发终端进行4步CFRA后,终端需要确定4步CFRA的RO资源信息,例如在CFRA配置信息中确定是否有为所述终端独立配置的RO资源信息,如果有为所述终端独立配置的RO资源信息,那么终端可以根据为所述终端独立配置的RO资源信息确定发起4步CFRA的RO;如果没有为所述终端独立配置的RO资源信息,可以根据4步CBRA的RO资源信息,确定触发的4步CFRA的RO资源信息。
根据本公开的实施例,网络侧设备可以指示终端根据指定版本的4步CBRA的RO资源信息,确定触发的4步CFRA的RO资源信息。从而即使为终端被配置了legacy版本的4步CBRA的RO资源信息和R17版本的4步CBRA的RO资源信息,也能端够使得终准确确定根据哪个版本的4步CBRA的RO资源信息,确定触发的4步CFRA的RO资源信息。避免了终端面对多个版本的4步CBRA的RO资源信息时,难以判断根据哪个版本的4步CBRA的RO资源信息确定4步CFRA的RO资源信息的技术问题。
需要说明的是,在相关技术(例如R15、R16)中,4步CBRA配置信息对应的信息元素为RACH-ConfigCommon,因此RACH-ConfigCommon默认是指legacy版本的4步CBRA配置信息。
根据本公开的实施例,为了明确指定版本具体是哪个版本,可以对信息元素RACH-ConfigCommon进行调整。
例如对于R17版本中的CBRA配置,可以通过不同的后缀区分于legacy版本中的CBRA配置,比如RACH-ConfigCommon-r17。
例如对于R17版本中的CBRA配置,可以通过不同的名称区分于legacy版本中的CBRA配置,比如RACH-ConfigCommonExt-R17。
在一个实施例中,所述指定版本包括以下至少之一:传统legacy版本、R17版本。在一个实施例中,所述传统legacy版本包括以下至少之一:R15版本、R16版本。
图8是根据本公开的实施例示出的另一种随机接入时机资源信息的指示方法的示意流程图。如图8所示,所述指示所述终端根据指定版本的4步竞争随机接入CBRA的随机接入时机RO资源信息,确定触发的4步CFRA的RO资源信息包括:
在步骤S801中,指示所述终端将所述指定版本的4步CBRA的RO资源信息中的RO配置信息,确定为触发的4步CFRA的RO资源信息的RO配置信息。
在一个实施例中,触发4步CFRA的方式可以包括PDCCH order触发;系统信息请求SI request触发;切换Handover命令触发等。
4步CBRA的RO资源信息主要包括的RO配置信息以及SSB和RO之间的对应关系,也即终端需要确定的RO配置信息以及SSB和RO之间的对应关系。
对于上述三种触发方式而言,在触发方式为系统信息请求SI request触发或者切换Handover命令触发时,终端需要根据指定版本的4步竞争随机接入CBRA的随机接入时机RO资源信息,确定触发的4步CFRA的RO资源信息中的RO配置信息以及SSB和RO之间的对应关系;
而在触发方式为PDCCH order触发的情况下,由于网络侧设备在PDCCH中会指示SSB索引、PRACH mask索引等信息,终端基于这些信息可以确定SSB与RO之间的对应关系,所以网络侧设备只需要指示终端根据指定版本的4步竞争随机接入CBRA的随机接入时机RO资源信息,确定触发的4步CFRA的RO资源信息中的RO 配置信息即可。
也即针对上述三种触发方式而言,网络侧设备都需要指示终端根据指定版本的4步竞争随机接入CBRA的随机接入时机RO资源信息,确定触发的4步CFRA的RO资源信息中的RO配置信息,例如可以指示终端将所述指定版本的4步CBRA的RO资源信息中的RO配置信息,确定为触发的4步CFRA的RO资源信息的RO配置信息;而在触发方式为系统信息请求SI request触发或者切换Handover命令触发时,网络侧设备还需要进一步指示终端确定触发的4步CFRA的RO资源信息中SSB和RO之间的对应关系,关于确定所述对应关系的内容,在后续实施例进行描述。
另外,在触发方式为PDCCH order触发的情况下,在本实施例中,网络侧设备可以不指示CFRA的RO资源信息中的RO配置信息,终端根据4步CBRA的RO资源信息中的RO配置信息,确定触发的4步CFRA的RO资源信息的RO配置信息;网络侧设备也可以通过PDCCH中的下行控制信息DCI(Downlink Control Information)指示CFRA的RO资源信息中的RO配置信息,终端根据DCI所指示的RO配置信息,确定触发的4步CFRA的RO资源信息的RO配置信息。
图9是根据本公开的实施例示出的又一种随机接入时机资源信息的指示方法的示意流程图。如图9所示,所述指示所述终端将所述指定版本的4步CBRA的RO资源信息中的RO配置信息,确定为触发的4步CFRA的RO资源信息的RO配置信息包括:
在步骤S901中,指示所述终端将所述legacy版本的4步CBRA的RO资源信息中的RO配置信息,确定为触发的4步CFRA的RO资源信息中的RO配置信息。

图10是根据本公开的实施例示出的又一种随机接入时机资源信息的确定方法的示意流程图。如图10所示,所述指示所述终端将所述指定版本的4步CBRA的RO资源信息中的RO配置信息,确定为触发的4步CFRA的RO资源信息的RO配置信息包括:
在步骤S1001中,指示所述终端在R17版本的多个4步CBRA的RO资源信息中,将部分或全部资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信 息中的RO配置信息。
在一个实施例中,指定版本可以为R17版本,由于在R17版本中针对不同的特性可以配置不同的CBRA配置信息,因此终端可以被配置R17版本的多个4步CBRA的RO资源信息。
在这种情况下,网络侧设备可以指示终端在R17版本的多个4步CBRA的RO资源信息中,将部分(可以是一个也可以是多个)资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息;也可以将全部资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息。
其中,网络侧设备指示终端终端在R17版本的多个4步CBRA的RO资源信息中将部分资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息,所述部分资源信息,可以基于预定义的R17的4步CBRA配置信息列表来确定,例如在列表中按照顺序排列多个RO配置信息,所述部分资源信息可以是列表中前n个配置信息,n为大于或等于1的整数。
另外,网络侧设备指示终端将全部资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息,是指全部资源信息中的RO配置信息所配置的RO对于终端而言可用的。
在一个实施例中,所述指示所述终端在R17版本的多个4步CBRA的RO资源信息中,将部分或全部资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息包括:
指示所述终端在R17版本的多个4步CBRA的RO资源信息中,将部分或全部资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息。
在一个实施例中,网络侧设备在指示终端根据R17版本的4步CBRA的RO资源信息,确定触发的4步CFRA的RO资源信息时,终端才在R17版本的多个4步CBRA的RO资源信息中,将部分或全部资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息。
而在网络侧设备没有指示终端根据R17版本的4步CBRA的RO资源信息中的RO配置信息,确定触发的4步CFRA的RO资源信息中的RO配置信息时,终端可以根据legacy版本的4步CBRA的RO资源信息中的RO配置信息,确定触发的4步CFRA 的RO资源信息中的RO配置信息。
在一个实施例中,所述指示所述终端在R17版本的多个4步CBRA的RO资源信息中,将部分或全部资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息包括:
在所述终端支持根据R17版本的4步CBRA的RO资源信息中的RO配置信息,确定触发的4步CFRA的RO资源信息中的RO配置信息时,指示所述终端在R17版本的多个4步CBRA的RO资源信息中,将部分或全部资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息;
所述方法还包括:
在所述终端不支持根据R17版本的4步CBRA的RO资源信息,确定触发的4步CFRA的RO资源信息,指示所述终端根据legacy版本的4步CBRA的RO资源信息中的RO配置信息,确定触发的4步CFRA的RO资源信息中的RO配置信息。
在一个实施例中,网络侧设备可以根据终端自身能力确定是否指示终端在R17版本的多个4步CBRA的RO资源信息中,将部分或全部资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息。
例如网络侧设备确定终端有能力支持根据R17版本的4步CBRA的RO资源信息,确定触发的4步CFRA的RO资源信息时(可以是指终端支持R17中引入的所述多个特性之一或组合),可以指示终端在R17版本的多个4步CBRA的RO资源信息中,将部分或全部资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息。
而在网络侧设备确定终端的能力不支持根据R17版本的4步CBRA的RO资源信息,确定触发的4步CFRA的RO资源信息时,则可以指示终端根据legacy版本的4步CBRA的RO资源信息中的RO配置信息,确定触发的4步CFRA的RO资源信息中的RO配置信息。
在一个实施例中,终端的能力还可以包括终端对Slicing、SDT、CE、Redcap等特性的支持情况。网络侧设备可以根据终端确定终端在所述特性中所支持的特性,那么网络侧设备可以在R17版本的多个4步CBRA的RO资源信息中确定终端所支持的特性对应的一个或多个4步CBRA的RO资源信息,进而指示终端在所确定的一个或多个4步CBRA的RO资源信息确定为触发的4步CFRA的RO资源信息中的RO 配置信息。
例如网络侧设备针对Slicing、SDT、CE、Redcap这4种特性分别为终端配置了R17版本的4个4步CBRA的RO资源信息,网络侧设备根据终端能力确定终端仅支持其中CE和Redcap两个特性,那么可以在R17版本的4个4步CBRA的RO资源信息中确定CE和Redcap特性对应的2个4步CBRA的RO资源信息,进而指示终端在所确定的2个4步CBRA的RO资源信息确定为触发的4步CFRA的RO资源信息中的RO配置信息。
图11是根据本公开的实施例示出的又一种随机接入时机资源信息的确定方法的示意流程图。如图11所示,所述指示所述终端将所述指定版本的4步CBRA的RO资源信息中的RO配置信息,确定为触发的4步CFRA的RO资源信息的RO配置信息包括:
在步骤S1101中,指示所述终端在legacy版本的4步CBRA的RO资源信息和R17版本的多个4步CBRA的RO资源信息中,将部分或全部资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息。
在一个实施例中,指定版本可以包括legacy版本和R17版本,由于在R17版本中针对不同的特性可以配置不同的CBRA配置信息,因此终端可以被配置R17版本的多个4步CBRA的RO资源信息。
在这种情况下,网络侧设备可以指示终端在legacy版本的4步CBRA的RO资源信息和R17版本的多个4步CBRA的RO资源信息中,将部分(可以是一个也可以是多个)资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息;也可以将全部资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息。
其中,当终端至少在R17版本的多个4步CBRA的RO资源信息中,网络侧设备指示终端将部分资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息时,所述部分资源信息,可以基于预定义的R17的4步CBRA配置信息列表来确定,例如在列表中按照顺序排列多个RO配置信息,所述部分资源信息可以是列表中前n个配置信息,n为大于或等于1的整数。
另外,网络侧设备指示终端终端将全部资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息,是指全部资源信息中的RO配置信 息所配置的RO对于终端而言都是可用的。
在一个实施例中,所述指示所述终端在legacy版本的4步CBRA的RO资源信息和R17版本的多个4步CBRA的RO资源信息中,将部分或全部资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息包括:
指示所述终端在legacy版本的4步CBRA的RO资源信息和R17版本的多个4步CBRA的RO资源信息中,将部分或全部资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息。
在一个实施例中,网络侧设备可以指示终端在legacy版本的4步CBRA的RO资源信息和R17版本的多个4步CBRA的RO资源信息中,将部分或全部资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息。
而若网络侧设备没有指示终端根据legacy版本的4步CBRA的RO资源信息和R17版本的4步CBRA的RO资源信息,确定触发的4步CFRA的RO资源信息时,终端可以根据legacy版本的4步CBRA的RO资源信息中的RO配置信息,确定触发的4步CFRA的RO资源信息中的RO配置信息。
在一个实施例中,所述指示所述终端在legacy版本的4步CBRA的RO资源信息和R17版本的多个4步CBRA的RO资源信息中,将部分或全部资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息包括:
在所述终端支持根据R17版本的4步CBRA的RO资源信息,确定触发的4步CFRA的RO资源信息时,指示所述终端在legacy版本的4步CBRA的RO资源信息和R17版本的多个4步CBRA的RO资源信息中,将部分或全部资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息;
所述方法还包括:
在所述终端不支持根据R17版本的4步CFRA的RO资源信息,确定触发的4步CFRA的RO资源信息时,指示所述终端根据legacy版本的4步CBRA的RO资源信息中的RO配置信息,确定触发的4步CFRA的RO资源信息中的RO配置信息。
在一个实施例中,网络侧设备可以根据终端能力确定是否指示终端在legacy版本的4步CBRA的RO资源信息和R17版本的多个4步CBRA的RO资源信息中,将部分或全部资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息。
例如网络侧设备确定终端有能力支持根据R17版本的4步CBRA的RO资源信息,确定触发的4步CFRA的RO资源信息时(可以是指终端支持R17中引入的所述多个特性之一或组合),可以指示终端在legacy版本的4步CBRA的RO资源信息和R17版本的多个4步CBRA的RO资源信息中,将部分或全部资源信息中的RO配置信息确定为触发的4步CFRA的RO资源信息中的RO配置信息。
而在网络侧设备确定终端能力不支持根据R17版本的4步CBRA的RO资源信息,确定触发的4步CFRA的RO资源信息时,可以指示终端根据legacy版本的4步CBRA的RO资源信息中的RO配置信息,确定触发的4步CFRA的RO资源信息中的RO配置信息。
在一个实施例中,终端的能力还可以包括终端对Slicing、SDT、CE、Redcap等特性的支持情况。终端可以确定自身能力在所述特性中所支持的特性,当终端至少在根据R17版本的4步CFRA的RO资源信息,确定触发的4步CFRA的RO资源信息时,终端可以在R17版本的多个4步CBRA的RO资源信息中确定所支持的特性对应的一个或多个4步CBRA的RO资源信息,进而在所确定的一个或多个4步CBRA的RO资源信息确定为触发的4步CFRA的RO资源信息中的RO配置信息。
例如网络侧设备针对Slicing、SDT、CE、Redcap这4种特性分别为终端配置了R17版本的4个4步CBRA的RO资源信息,终端的能力仅支持其中CE和Redcap两个特性,那么终端可以在R17版本的4个4步CBRA的RO资源信息中确定CE和Redcap特性对应的2个4步CBRA的RO资源信息,进而在所确定的2个4步CBRA的RO资源信息确定为触发的4步CFRA的RO资源信息中的RO配置信息。

而在触发方式为系统信息请求SI request触发或者切换Handover命令触发时,网络侧设备需要进一步指示终端确定触发的4步CFRA的RO资源信息中SSB和RO之间的对应关系,具体可以指示终端按照指定方式确定触发的4步CFRA的RO资源信息中SSB和RO之间的对应关系。进而终端才能根据RO配置信息和所述对应关系确定触发的4步CFRA所使用的RO。

在一个实施例中,终端在基于前述实施例将所述指定版本的4步CBRA的RO资源信息中的RO配置信息,确定为触发的4步CFRA的RO资源信息的RO配置信息后,可以根据网络侧设备预先配置给所述终端的所有版本的4步CBRA的RO资源信息(而不必局限在述指定版本的4步CBRA的RO资源信息)中同步信号块SSB和RO之间的对应关系,确定触发的4步CFRA的RO资源信息中SSB和RO之间的对应关系。
需要说明的是,当在网络侧设备预先配置给所述终端的所有版本的4步CBRA的RO资源信息中存在多个SSB和RO之间的对应关系时,终端可以在其中确定一个SSB和RO之间的对应关系,其中,SSB和RO之间的对应关系通过数值表征,例如1/8、1/4、1/2、1、2、4、8、16等,终端可以选择其中一个数值,例如选择其中最大值或最小值。
