随机接入方法、装置、终端及网络侧设备
相关申请的交叉引用
本公开主张在2021年12月14日在中国提交的中国专利申请号No.202111527730.3的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及无线技术领域,尤其是指一种随机接入方法、装置、终端及网络侧设备。
背景技术
目前,为了实现覆盖增强的目的,引入了覆盖增强(Coverage Enhancement,CovEnh)特性。CovEnh特性用户设备(User Equipment,UE,其也称之为“终端”)通过第3消息(Msg3)物理上行共享信道(Physical Uplink Shared Channel,PUSCH)重复传输,即便处于小区边缘时也可以有更大可能性连接到基站(如5G基站(5G NodeB,gNB)。为此引入一个独立的参考信号接收功率(Reference Signal Receiving Power,RSRP)阈值第一门限,CovEnh UE利用第一门限判断是否执行Msg3重复传输。相关技术中,主要专注于4步基于竞争的随机接入过程(4-step Contention Based Random Access,4-step CBRA)类型的Msg3重复传输。
CovEnh UE随机接入资源选择过程中,在进行同步信号块(Synchronization signal Block,SSB)选择时,在所有SSB对应的同步信号参考信号接收功率(Synchronization Signal-Reference Signal Received Power,SS-RSRP)均小于或等于SSB的rsrp阈值rsrp-ThresholdSSB时,任意选择一个SSB用于执行随机接入,并在相应的下行路径损失参考的RSRP小于或等于第一门限时,在随机接入时执行4-step CBRA Msg3重复过程。
相关技术中,上述的Msg3重复过程适用于所有的SSB,但Msg3重复会占用比较大的随机接入资源,当所有SSB对应的SS-RSRP都小于或等于rsrp-ThresholdSSB时,如果所有SSB都支持做Msg3重复传输,则存在资源 浪费的问题,且会对传统终端UE的信息传输造成影响。

为解决相关技术中,Msg3重复过程适用于所有的SSB,但Msg3重复会占用比较大的随机接入资源,当所有SSB对应的SS-RSRP都小于或等于rsrp-ThresholdSSB时,如果所有SSB都支持做Msg3重复传输,则存在资源浪费,且会对传统终端UE的信息传输造成影响的问题,本公开实施例提供一种随机接入方法。
如图1所示,本公开其中一实施例所述随机接入方法,由终端执行,所述方法包括:
S110,获取网络侧设备发送的第一配置信息;所述第一配置信息用于指示同步信号块SSB是否支持覆盖增强;
S120,根据所述第一配置信息,选择支持覆盖增强的SSB执行Msg3重复发送。
采用本公开实施例所述随机接入方法,终端根据网络侧设备发送的用于指示同步信号块SSB是否支持覆盖增强的第一配置信息,通过第一配置信息指示的支持覆盖增强的SSB执行Msg3重复发送,终端可以选择部分SSB执行Msg3重复的随机接入过程,避免造成资源浪费的问题。
目前,引入覆盖增强CovEnh特性的目的是为了实现覆盖增强,CovEnh UE通过Msg3 PUSCH重复传输,即便处于小区边缘时也可以有更大可能性连接到gNB。可选地,本公开实施例中,Msg3重复传输主要应用于4-step CBRA类型的随机接入中。

具体地,在执行4-step CBRA的Msg3重复传输时,包括资源选择过程和Msg3重复传输的4-step CBRA,其中一实施方式,资源选择过程包括如下步骤:
S210,网络侧设备通过无线资源控制(Radio Resource Control,RRC)为随机接入配置参数;
S220,载波选择;
其中,如果用于随机接入的载波被明确指示,则选择该载波执行随机接入过程;
如果没有明确用于随机接入的载波,并且服务小区被配置为支持补充上行链路(Supplementary Uplink Carrier,SUL),则:在下行路径损耗的RSRP小于用于选择SUL或正常上行链路(Normal Uplink Carrier,NUL)的RSRP阈值参数rsrp-ThresholdSSB-SUL的情况下,选择SUL载波执行随机接入过程;否则,选择NUL载波执行随机接入过程。
S230,随机接入信道(Random Access Channel,RACH)类型选择;
由于CovEnh场景下主要关注4-step CBRA过程,此时随机接入(Random Access,RA)类型RA_TYPE设置为4-stepRA。
S240,SSB选择;
S250,前导码(Preamble)选择;
根据步骤S240选定的SSB,选择相关联的Preamble,并将前导码索引PREAMBLE_INDEX设置为选定的Preamble;
S260,执行随机接入过程。
相关技术中,在步骤S210,网络侧设备通过RRC为随机接入配置参数时,所配置参数包括第一门限,该第一门限为用于判断SSB是否执行Msg3重复发送的第一测量参数的阈值;可选地,该第一测量参数可以为基于第二测量参数计算的下行路径损耗参数;其中,第二测量参数包括参考信号接收功率RSRP、参考信号接收质量(Reference Signal Receiving Quality,RSRQ)和接收信号强度指示(Received Signal Strength Indication,RSSI)中的至少之一。第一测量参数为基于该第二测量参数中的至少之一计算的下行路径损耗参数。
举例说明,在第二测量参数包括RSRP的情况下,第一测量参数可以为下行路径损耗的RSRP,第一门限为下行路径损耗的RSRP的阈值。
另外,相关技术中,在步骤S260,执行随机接入过程时,根据SSB测量结果,存在至少有一个SSB,对应的第二测量参数(如为同步信号参考信号接收功率SS-RSRP)大于第二门限(可选地为SSB rsrp阈值rsrp-ThresholdSSB)的情况,没有关于是否执行Msg3重复传输的规定,因此流程不完善;在根据SSB测量结果,全部SSB的测量参数均小于或等于第二门限时,则进一步判断步骤S240所确定的选定SSB的第一测量参数(可选地为下行路径损耗的RSRP)是否大于第一门限,在选定SSB的下行路径损耗的RSRP大于第一门限的情况下,执行通常的4-step CBRA过程,也即不执行Msg3重复传输;在选定SSB的下行路径损耗的RSRP小于或等于第一门限的情况下,执行4-step CBRA Msg3重复过程。
需要说明的是,本公开实施例中,第二门限不限于为SSB rsrp的阈值,如可以为SSB rsrp的阈值、SSB RSRQ的阈值和SSB RSSI的阈值中的至少之一。

S330,RACH类型选择;
由于CovEnh场景下主要关注4-step CBRA过程,此时随机接入类型RA_TYPE设置为4-stepRA;

该第一门限为用于判断是否执行Msg3重复发送的第一测量参数的阈值;可选地,该第一测量参数为基于第二测量参数计算的下行路径损耗;其中,第二测量参数包括RSRP、RSRQ和RSSI中的至少之一。第一测量参数为基于该第二测量参数中的至少之一计算的下行路径损耗。
例如,以第一门限为下行路径损耗的RSRP的阈值为例,根据SSB测量结果,在下行路径损耗的参考信号接收功率RSRP值大于第一门限时,确定SSB测量结果不符合Msg3重复发送条件,则执行步骤S350;在下行路径损耗的参考信号接收功率RSRP值小于或等于第一门限时,确定SSB测量结果符合Msg3重复发送条件,则执行步骤S360;

其中,第一Preamble集合为特定的用于覆盖增强的Preamble集合;第二Preamble集合为特定的用于传统基于基站竞争的4-step RA的Preamble集合。

以下对所述第一配置信息用于指示SSB是否支持覆盖增强的方式进行说明。
实施方式一
第一配置信息包括第一指示信息,用于指示支持覆盖增强的SSB;或者,包括第二指示信息,用于指示不支持覆盖增强的SSB;或者包括第三指示信息,用于指示SSB是否支持覆盖增强。
可选地,第一指示信息可以为第一标识,通过位图(bitmap)形式指示支持覆盖增强的SSB,如通过SSB所对应的位图标识为第一值,指示相应的SSB支持覆盖增强;第二指示信息可以为第二标识,通过位图(bitmap)形式指示不支持覆盖增强的SSB,如通过SSB所对应的位图标识为第二值,指示相应的SSB不支持覆盖增强;第三指示信息可以为第三标识,通过位图(bitmap)形式指示SSB是否支持覆盖增强,如通过SSB所对应的位图标识为第一值,指示该SSB支持覆盖增强;通过SSB所对应的位图标识为第二值,指示该SSB不支持覆盖增强。需要说明的是,第一指示信息、第二指示信息和第三指示信息并不限于仅能够通过bitmap形式指示SSB。

该实施方式中,可选地,网络侧设备通过RRC为随机接入配置参数时还指示第一配置信息,该第一配置信息通过第一指示信息指示支持覆盖增强的SSB,或者,第一配置信息通过第二指示信息指示不支持覆盖增强的SSB,或者,第一配置信息通过第三指示信息指示SSB是否支持覆盖增强。
另外,本公开实施例中,第一门限适用于所有支持覆盖增强的SSB,也即在进行Msg3重复发送时,选定SSB为每一支持覆盖增强的SSB时,根据第一门限判断是否采用选定SSB执行Msg3重复发送。
实施方式二
第一配置信息包括对应支持覆盖增强的SSB配置的第一门限。具体地,采用该实施方式,对应支持覆盖增强的SSB配置的第一门限为特定的第一门限,也即为用于支持覆盖增强的SSB配置特定的第一门限。
该实施方式中,可选地,该第一配置信息可以在网络侧设备通过RRC为随机接入配置参数时指示。
可选地,网络侧设备通过RRC为随机接入配置参数时,除包括所配置的第一门限外,还配置以下至少之一参数:
用于选择SUL或NUL的RSRP阈值rsrp-ThresholdSSB-SUL;

标识选定的Preamble的随机接入前导码索引ra-PreambleIndex参数。
可选地,在第一配置信息中,对应每一支持覆盖增强的SSB,分别配置一个特定的第一门限,不同SSB所配置的第一门限可以相同或不同。
采用该实施方式,终端根据网络侧设备所指示的随机接入配置参数中,是否为SSB配置特定的第一门限,判断相应的SSB是否为支持覆盖增强的SSB。
实施方式三
第一配置信息包括对应支持覆盖增强的SSB配置的特定传输资源,其中,配置所述特定传输资源的相应SSB为支持覆盖增强的SSB,也即通过为部分 的SSB配置特定传输资源,标识能够支持覆盖增强的SSB。
可选地,特定传输资源包括Preamble和/或物理随机接入信道(Physical Random Access Channel,PRACH)资源。
采用该实施方式,UE根据SSB是否配置了特定Preamble或特定PRACH资源,确定该选定SSB是否为支持覆盖增强的SSB。
可选地,该实施方式中,网络侧设备可以为不同SSB配置不同或相同的特定传输资源。
实施方式四
第一配置信息包括对应支持覆盖增强的SSB配置的第二门限;所述第二门限为用于SSB选择的第二测量参数的阈值;可选地,该第二测量参数包括SSB rsrp、SSB RSRQ和SSB RSSI中的至少之一。
其中,部分SSB配置特定的第二门限,配置特定的第二门限的相应SSB为支持覆盖增强的SSB。
采用该实施方式,终端根据选定SSB是否配置了特定第二门限,如配置特定rsrp-ThresholdSSB,确定该SSB是否支持覆盖增强。
本公开实施例所述随机接入方法,可选地,所述方法还包括:
获取网络侧设备发送的一个或多个第一门限;所述第一门限为用于判断SSB是否执行Msg3重复发送的第一测量参数的阈值。
可选地,网络侧设备通过RRC为随机接入配置参数时,所配置参数中包括该第一门限。
其中一实施方式,如图2所示,在随机接入的资源选择过程,在选定SSB后,可以利用第一门限判断是否执行Msg3重复发送。
例如,在第一门限为下行路径损耗的RSRP的阈值时,在测定SSB的下行路径损耗的RSRP大于第一门限的情况下,执行通常的4-step CBRA过程,也即不执行Msg3重复传输;在下行路径损耗的RSRP小于或等于第一门限的情况下,执行4-step CBRA Msg3重复过程。
可选地,测定SSB可以为多个SSB中信号质量最优的SSB,当然也不限于信号质量最优SSB,也可以根据预设配置确定。通过将该测定SSB测量结果中的第一测量参数与第一门限比较,能够判断是否执行Msg3重复发送。
另一实施,如图3所示,在随机接入的资源选择过程,在选定SSB之前,根据SSB测量结果和第一门限,判断SSB测量结果是否符合Msg3重复发送条件;
例如,在下行路径损耗的参考信号接收功率RSRP值大于第一门限时,确定SSB测量结果不符合Msg3重复发送条件;在下行路径损耗的参考信号接收功率RSRP值小于或等于第一门限时,确定SSB测量结果符合Msg3重复发送条件。
根据以上,本公开实施例中,其中一实施方式,根据所述第一配置信息,选择支持覆盖增强的SSB执行Msg3重复发送,包括:
根据SSB测量结果和所述第一门限,判断所述SSB的测量结果中的第一测量参数是否满足所述第一门限;

具体地,在SSB满足第一条件时,第一配置信息所指示的支持覆盖增强的SSB对应其中的第一个第一门限;在SSB满足第二条件时,第一配置信息所指示的支持覆盖增强的SSB对应其中的第二个第一门限。其中,第一个第一门限和第二个第二门限分别为多个第一门限中的任一第一门限。
可选地,在获取所述网络侧设备发送的多个第一门限为两个的情况下,所述SSB满足第一条件时,所述第一配置信息所指示的支持覆盖增强的SSB对应两个第一门限中的其中一个第一门限;或者,当所述SSB满足第二条件时,所述第一配置信息所指示的支持覆盖增强的SSB对应两个第一门限中的 另外一个第一门限。本公开实施例中,可选地,所述第一条件为每一所述SSB的第二测量参数均小于或等于第二门限;或者,所述第二条件为至少存在一个SSB的第二测量参数大于所述第二门限。
采用该实施方式,根据SSB测量结果满足的不同条件,可以选择不同的第一门限,进行是否执行Msg3重复发送的判断。通过该方式,可以避免在不同SSB条件下都执行Msg3重复,仅仅配置一个第一门限,造成SSB条件变化时,第一门限的频繁配置问题。
本公开实施例中,可选地,根据图3,用于确定执行Msg3重复发送的预设条件包括以下其中之一:
每一所述SSB的第二测量参数均小于或等于第二门限;
至少存在一个SSB的第二测量参数大于所述第二门限。
本公开实施例中,在每一所述SSB的第二测量参数均小于或等于第二门限,以及至少存在一个SSB的第二测量参数大于所述第二门限,该两个条件下,均选择支持覆盖增强的SSB,执行Msg3重复发送。
相较于相关技术,对于至少存在一个SSB的第二测量参数大于所述第二门限的情况,是否需要执行Msg3重复发送及后续流程并不完善,本公开实施例所述随机接入方法,明确了该条件下执行Msg3重复发送,且执行Msg3重复发送的选定SSB的确定方式。
需要说明的是,对于至少存在一个SSB的第二测量参数大于所述第二门限的情况,也可以规定为不执行Msg3重复发送。
可选地,在每一所述SSB的第二测量参数均小于或等于第二门限的情况下,所述选择支持覆盖增强的SSB执行Msg3重复发送,包括:

可选地,在至少存在一个SSB的第二测量参数大于所述第二门限的情况下,所述选择支持覆盖增强的SSB执行Msg3重复发送,包括:
从第二测量参数大于所述第二门限的SSB中,选择所述第一配置信息指示的支持覆盖增强的SSB,执行Msg3重复发送;或者
