本申请实施例中,所述"协议"可以指通信领域的标准协议,例如可以包括LTE协议、NR协议以及应用于未来的通信***中的相关协议,本申请对此不做限定。
在NR***中,终端设备通过随机接入的方式建立、重建、或者恢复一个无线资源控制(Radio Resource Control,RRC)连接,或者,在已建立RRC连接的情况下,通过随机接入的方式来达到上行同步、功率控制的初始化的目的。
在NR***中,终端设备可以使用小区内公共使用的随机接入无线资源发起随机接入过程。随机接入无线资源在时频域上的最小单位称为随机接入信道时机(Random Access Channel Occasion,RACH Occasion,简称RO)。
在一些场景中,一个RO内可以有64个preamble,一个无线帧的长度可以是10毫秒,包含10个长度为1毫秒的子帧。一个子帧包含的时隙的个数和这个载波的子载波间隔(Subcarrier spacing,SCS)有关。子载波间隔为15KHz的载波上的一个子帧为1个时隙,其他的子载波间隔包含K个时隙,其中K等于其他的子载波间隔和15KHz的比值。比如对于120KHz的SCS,一个子帧可以包含8个时隙。一个时隙内一共有14个符号。一个RO在时域上可以是一个时隙内的几个符号,即一个时隙内可以包含多个RO;或者跨越几个时隙,即几个时隙构成一个RO。一个RO在频域上由几个连续的物理资源块(Physical Resource Block,PRB)组成。在一个无线帧内的RO配置在时域上按照一定的周期重复。
图2是一种RO配置的示意图,其中,每个方格表示一个RO。如图2所示,在一个无线帧内包括的两个子帧(假设SCS=15KHz,子帧即为时隙)上配置有RO,对于每个子帧,在频域上一共有4个RO。图2所示的RO配置按照一个无线帧的周期进行重复。
在NR***中,终端设备可以从多个同步信号块(Synchronization Signal Block, SSB)中选择用于随机接入的SSB,其中,每个SSB关联相应的RO资源,终端设备可以在选择的SSB所关联的RO资源中确定发送前导码(preamble)的RO资源。
在一些实施例中,SSB和RO资源可以按照如下方式关联:
步骤a,每个RO中,按照preamble索引递增的顺序而递增;
步骤b,在相同时域内,按照RO的频域资源所在位置从低到高递增;
步骤c,在PRACH时隙内,按照RO的时域资源的顺序递增;
步骤d,按照PRACH时隙的顺序递增。
即,所述终端设备按照RO内,RO间,PRACH时隙内,PRACH时隙间的顺序依次进行SSB波束到RO资源的映射。其中,该PRACH时隙可以指包括RO的时隙。
在一些场景中,对于新引入的随机接入触发条件,可以采用如下配置随机接入无线资源,例如,配置用于该随机接入触发条件的专用随机接入无线资源,又例如,共享部分已配置的随机接入无线资源。
在一些场景中,若一个载波上与一个SSB所关联的RO资源个数大于1,RO的共享方式可以有如下三种:
1、共享一个RO资源;
2、共享索引为偶数的RO资源;
3、共享索引为奇数的RO资源。
图3是一个SSB在一个无线帧内所关联的RO资源的示意图。在一个子帧中,一个SSB关联4个RO,按照上述共享方式,可以被共享的RO的序号为{1},{2},{3},{4},{1,3},{2,4}。若一个RO关联的SSB大于等于1,该RO的共享方式只有一种,即要么该RO共享,要么该RO不共享。
在一些场景中,一个SSB关联的RO资源的个数可以为1,2,4或8。则当一个SSB关联4个RO资源或8个RO资源时,共享RO资源的方式分别为6种和10种。当引入更多的随机接入触发条件,例如大于8种时,可以共享的随机接入无线资源受限。而新的随机接入触发条件发生的频度和随机接入冲突概率的要求会不一样,采用上述共享方式会导致所共享的RO资源在不同的随机接入触发条件之间不均衡,因此,如何实现RO资源的灵活共享是一项亟需解决的问题。
为便于理解本申请实施例的技术方案,以下通过具体实施例详述本申请的技术方案。以上相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
图4是根据本申请实施例的无线通信的方法200的示意性流程图,该方法200可以由图1所示的通信***中的终端设备执行,如图4所示,该方法200包括如下内容:
S210,在基于第一触发条件发起随机接入的情况下,终端设备根据第一指示信息,确定第一随机接入信道机会RO资源集合中共享给所述第一触发条件的随机接入的目标RO资源,所述第一指示信息用于指示所述第一RO资源集合中共享给所述第一触发条件的随机接入的RO资源。
进一步地,所述方法200还包括:
S220,所述终端设备根据所述目标RO资源发起第一触发条件的随机接入。
应理解,在本申请实施例中,所述RO资源也可以替换为PRACH资源,或者,随机接入无线资源,或者,随机接入资源。
例如,若所述目标RO资源包括一个RO资源,所述终端设备可以在所述一个RO资源上发起第一触发条件的随机接入。
又例如,若所述目标RO资源包括多个RO资源,所述终端设备可以在该多个RO资源中选择一个RO资源,发起第一触发条件的随机接入。
在一些实施例中,所述第一触发条件可以为新引入的随机接入触发条件,或者,也可以为已有的随机接入触发条件。
在一些实施例中,所述第一RO资源集合可以为用于第二触发条件的随机接入的RO资源,所述第二触发条件可以为已有的随机接入触发条件,或者,也可以为新引入的随机接入触发条件。
在一些实施例中,所述第二触发条件可以为以下中的至少一种:建立RRC连接、重建RRC连接、恢复RRC连接,上行同步、初始化功率控制。
在一些实施例中,所述第一RO资源集合可以为已配置的随机接入无线资源,例如小区内公共使用的随机接入无线资源,或者,也可以为新配置的随机接入无线资源。
即,本申请实施例提供的RO资源的共享方式可以适用于已配置的随机接入无线资源,也可以适用于新配置的随机接入无线资源。
在一些实施例中,所述第一RO资源集合与第一同步信号块SSB关联。
在一些实施例中,所述第一SSB为所述终端设备选择的用于所述第一触发条件的随机接入的SSB。
例如,所述终端设备可以根据网络设备发送的SSB的参考信号接收功率(Reference Signal Receiving Power,RSRP)门限值(rsrp-ThresholdSSB)确定该第一SSB。
在一些实施例中,所述第一指示信息用于指示所述第一SSB关联的第一RO资源集合中的RO资源共享给第一触发条件的随机接入的目标RO资源。
即,所述终端设备在确定基于所述第一SSB发起随机接入时,可以根据所述第一指示信息在该第一SSB关联的第一RO资源集中确定共享给第一触发条件的随机接入的目标RO资源,进一步可以在该目标RO资源中选择一个RO资源发起第一触发条件的随机接入。
在另一些实施例中,当终端设备发起第三触发条件的随机接入时,并且终端设备选择第一SSB进行随机接入时,终端设备可以根据第二指示信息,在该第一SSB关联的第一RO资源集中确定共享给第三触发条件的随机接入的目标RO资源,进一步可以在该目标RO资源中选择一个RO资源发起第二触发条件的随机接入,其中,所述第二指示信息用于指示所述第一RO资源集合中共享用于所述第三触发条件的随机接入的RO资源。
应理解,本申请仅以终端设备选择第一SSB进行发起第一触发条件的随机接入为例进行说明,在终端设备选择其他SSB,或者发起其他触发条件的随机接入时,只需替换为相应的RO资源集和指示信息即可,本申请并不限于此。
在本申请一些实施例中,所述第一指示信息通过位图(bitmap)方式指示所述第一RO资源集合中共享用于所述第一触发条件的随机接入的RO资源。
采用位图方式指示每个RO资源的共享方式,能够实现RO资源的灵活指示,有利于满足随机接入触发条件增多情况下的RO资源分配问题,并且有利于避免共享的RO资源在不同的触发条件之间的不均衡问题。
以下,结合所述SSB和RO资源的两种映射关系分别说明RO资源的共享方式。
情况1:一个SSB关联多个RO资源。
此情况下,可以通过位图方式指示该多个RO资源中的每个RO资源的共享方式,即是否共享。
在一些实施例中,所述第一RO资源集合包括所述第一SSB在一个RO配置周期内所关联的一组RO资源,所述一组RO资源包括多个RO资源。
作为示例,所述一组RO资源包括2个RO资源,4个RO资源或8个RO资源。
应理解,一个RO配置周期可以指RO资源的重复周期,例如,可以为一个无线帧,一个子帧,或者一个时隙等,本申请对此不作限定。
在一些实施例中,所述第一指示信息通过位图方式指示所述一组RO资源中共享用于所述第一触发条件的随机接入的RO资源。
即在一个SSB在一个RO配置周期内关联多个RO资源时,可以采用位图指示该多 个RO资源的共享方式。
例如,所述第一指示信息包括第一位图,所述第一位图包括多个比特,每个比特对应所述一组RO资源中的一个RO资源,每个比特的取值用于指示对应的RO资源是否共享用于所述第一触发条件的随机接入。作为示例,取值为1表示对应的RO资源共享用于第一触发条件的随机接入,取值为0表示对应的RO资源不共享用于第一触发条件的随机接入。
以图3所示的SSB关联的RO资源举例说明。在一个RO配置周期内,一个SSB关联4个RO,则所述第一位图可以为4比特(记为B3~B0),分别对应RO资源4~RO资源1。
例如,若该4个RO资源中共享给第一触发条件的随机接入的RO资源为RO资源1,则第一位图可以为0001。
又例如,若该4个RO资源中共享给第一触发条件的随机接入的RO资源为RO资源2和RO资源3,则第一位图可以为0110。
再例如,若该4个RO资源中共享给第一触发条件的随机接入的RO资源为RO资源3和RO资源4,则第一位图可以为1100。
以图3所示的SSB关联的RO资源为例,假设该SSB关联的RO资源共享给三个触发条件,触发条件A~C,表1示出了SSB关联的RO资源中共享给这三种触发条件的RO资源。
表1
Figure PCTCN2021110853-appb-000001
由表1可知,SSB关联的4个RO资源中,共享给触发条件A的RO资源为RO资源1,共享给触发条件B的RO资源为RO资源2和RO资源3,共享给触发条件C的RO资源为RO资源3和RO资源4。则用于指示该SSB关联的RO资源集共享给触发条件A的RO资源的位图可以为0001,用于指示该SSB关联的RO资源集共享给触发条件B的RO资源的位图可以为0110,用于指示该SSB关联的RO资源集共享给触发条件C的RO资源的位图可以为1100。
综上,若一个SSB在一个RO配置周期内关联M个RO,根据前文所述的三种共享方式,可以有M+2种共享的RO组合,根据本申请的位图指示的共享方式可以有2^M-1种共享的RO组合。表2是M为不同的取值时,共享RO组合数的对比表,从表2可以看出,根据本申请实施例的共享方式可以提升共享RO组合数,进一步可以支持更多种触发条件导致的随机接入。
表2
Figure PCTCN2021110853-appb-000002
在一些实施例中,所述第一位图适用于所述第一SSB在每个RO配置周期内所关联的一组RO资源。
即对于第一SSB在每个RO配置周期内所关联的一组RO资源,均基于第一位图确 定RO资源的共享方式。换言之,在每个RO配置周期内,该第一SSB关联的一组RO资源中共享给同一触发条件的RO资源是相同的,或者说,在RO配置周期之间,用于指示第一SSB关联的一组RO资源的共享方式的位图是相同的。
情况2:一个RO关联一个或多个SSB。
此情况下,可以考虑一个SSB在多个RO配置周期内所关联的RO资源进行共享。
在一些实施例中,在每个RO配置周期内,所述第一SSB关联一个RO资源,所述第一RO资源集合包括所述第一SSB在N个RO配置周期内所关联的N个RO资源,其中,所述N为正整数。
在一些实施例中,所述N是预定义的,或者是网络设备配置的。
可选地,所述N为4,或者8。
即在一个SSB在一个RO配置周期内仅关联一个RO资源时,可以考虑N个RO配置周期内的RO资源进行共享,这种共享方式不局限于一个RO配置周期内SSB所关联的RO资源,有利于解决随机接入无线资源受限时的随机接入无线资源共享问题,并且有利于避免共享随机接入无线资源时导致的随机接入冲突问题。
在一些实施例中,所述N的大小可以根据所述第一SSB关联的RO资源需要共享的随机接入触发条件的个数确定。例如,若所述第一SSB关联的RO资源需要共享给两个随机接入触发条件,则所述N可以为2。又例如,若所述第一SSB关联的RO资源需要共享给三个随机接入触发条件,则所述N可以为3。
在一些实施例中,所述N个RO资源中的至少一个RO资源共享用于所述第一触发条件的随机接入。
在一些实施例中,所述N个RO资源中的第K个RO资源共享用于所述第一触发条件的随机接入。换言之,所述N个RO配置周期内的第K个RO配置周期内的RO资源共享用于所述第一触发条件的随机接入。
可选地,K是预定义的,或者是网络设备配置的。
可选地,所述第一指示信息可以包括所述N和所述K。
即在一些实施例中,所述终端设备根据N和K即可获知第一RO资源集合中共享给第一触发条件的随机接入的RO资源。
在另一些实施例中,所述第一指示信息通过位图方式指示所述N个RO资源中共享用于所述第一触发条件的随机接入的RO资源。
例如,所述第一指示信息包括第二位图,所述第二位图包括N个比特,每个比特对应所述N个RO资源中的一个RO资源,所述每个比特的取值用于指示对应的RO资源是否共享用于所述第一触发条件的随机接入。作为示例,取值为1表示对应的Ro资源共享用于第一触发条件的随机接入,取值为0表示对应的RO资源不共享用于第一触发条件的随机接入。
在一些实现方式中,所述第二位图用于指示所述N个RO资源中的一个RO资源共享用于所述第一触发条件的随机接入。例如,所述第一位图中的N个比特中只有一个比特的取值为1,表示该仅该比特对应的RO资源共享给第一触发条件的随机接入。
举例说明,一个载波上共有4个实际发送的SSB,一个RO可以关联到2个SSB。在一个PRACH时隙中配置了2个RO。那么SSB和RO之间的关联关系如表3所示。
表3
Figure PCTCN2021110853-appb-000003
即如图5所示,SSB1和SSB2关联RO资源1,SSB3和SSB3关联RO资源2。
若有两个随机接入触发条件共享SSB关联的RO资源,则可以考虑2个RO配置周期内的RO资源进行RO资源共享。例如,触发条件A共享2个RO配置周期中的第一个RO配置周期内的RO资源,触发条件B共享2个RO配置周期中的第二个RO配置周期内的RO资源。
例如,终端设备选择SSB3进行随机接入,随机接入的触发条件是触发条件A,则终端设备在SSB3在第一个RO配置周期内关联的RO资源上发送preamble。
又例如,终端设备选择SSB3进行随机接入,随机接入的触发条件是触发条件B,则终端设备在SSB3在第二个RO配置周期内关联的RO资源上发送preamble。
在本申请一些实施例中,网络设备在半个无线帧内发送的每个SSB对应相同的位图,所述位图用于指示所述每个SSB关联的RO资源集合共享用于所述第一触发条件的随机接入的RO资源。
也就是说,对于半帧内发送的每个SSB,共享给同一触发条件的RO资源是相同的。
例如,网络设备在半帧内发送两个SSB,SSB1和SSB2,每个SSB均关联4个RO资源,则这两个SSB关联的RO资源的共享方式相同,例如,对于SSB1共享给触发条件A的RO资源为RO资源1和RO资源2,则SSB2共享给触发条件A的RO资源也为RO资源1和RO资源2。
综上,在一个SSB关联多个RO资源的情况下,通过位图方式指示该SSB关联的多个RO资源的共享方式,提升了RO共享方式的灵活性,同时有利于避免共享RO资源在不同的随机接入触发条件之间的不均衡问题。
另外,在一个SSB关联一个RO资源的情况下,考虑该SSB在N个RO配置周期内关联的RO资源进行共享,有利于避免在随机接入无线资源受限时,并且需要共享随机接入无线资源给新增的随机接入触发条件时导致的随机接入冲突问题。

S310,网络设备向终端设备发送第一信息,所述第一信息用于指示目标随机接入信道机会RO资源集合中共享用于至少一个触发条件的随机接入的RO资源。
在一些实施例中,所述目标RO资源集合可以对应特定SSB,例如第一SSB,或者,也可以对应所有SSB。
即网络设备可以配置对于每个SSB关联的RO资源集合中的RO资源的共享方式,或者,也可以配置一个SSB关联的RO资源集合中的RO资源的共享方式,这种情况下,该共享方式可以适用于所有SSB。
例如,所述第一信息可以包括多个SSB分别关联的RO资源集合中的RO资源对于至少一个触发条件的随机接入的RO共享方式。
又例如,所述第一信息包括一个SSB关联的RO资源集合中的RO资源对于至少一个触发条件的随机接入的RO共享方式,该RO共享方式适用于网络设备在半帧内发送的所有SSB。
即所述第一信息所指示的RO共享方式可以是SSB粒度的,也可以是不区分SSB的,即对于所有SSB关联的RO的共享方式相同。
在一些实施例中,所述第一信息所指示的RO共享方式是触发条件粒度的,即对于同一RO资源集合,所述第一信息可以包括每个触发条件在该RO资源集合中共享的RO资源的指示信息。
以下,以第一SSB关联的RO资源集合中共享用于第一触发条件的随机接入的RO资源的指示方式为例进行说明,但本申请并不限于此。
例如,所述第一信息包括第一指示信息,所述第一指示信息用于指示第一RO资源集合中共享用于第一触发条件的随机接入的RO资源,其中,所述第一RO资源集合为所述第一SSB关联的RO资源集合。
在本申请一些实施例中,所述第一指示信息通过位图方式指示所述第一RO资源集合中共享用于第一触发条件的随机接入的RO资源。
在一些实施例中,所述第一RO资源集合包括所述第一SSB在一个RO配置周期内所关联的一组RO资源,所述一组RO资源包括多个RO资源。
作为示例,所述一组RO资源包括2个RO资源,4个RO资源或8个RO资源。
在一些实施例中,所述第一指示信息通过位图方式指示所述一组RO资源中共享用于所述第一触发条件的随机接入的RO资源。
例如,所述第一指示信息包括第一位图,所述第一位图包括多个比特,每个比特对应所述一组RO资源中的一个RO资源,每个比特的取值用于指示对应的RO资源是否共享用于所述第一触发条件的随机接入。
在一些实施例中,所述第一位图适用于所述第一SSB在每个RO配置周期内所关联的一组RO资源。
在另一些实施例中,在每个RO配置周期内,所述第一SSB关联一个RO资源,所述第一RO资源集合包括所述第一SSB在N个RO配置周期内所关联的N个RO资源,其中,所述N为正整数。
在一些实施例中,所述N个RO资源中的第K个RO资源共享用于所述第一触发条件的随机接入,其中,K是预定义的,或者是网络设备配置的。
在一些实施例中,所述第一指示信息通过位图方式指示所述N个RO资源中共享用于所述第一触发条件的随机接入的RO资源。
在一些实施例中,所述第一指示信息包括第二位图,所述第二位图包括N个比特,每个比特对应所述N个RO资源中的一个RO资源,每个比特的取值用于指示对应的RO资源是否共享用于所述第一触发条件的随机接入。
在一些实施例中,所述第二位图用于指示所述N个RO资源中的一个RO资源共享用于所述第一触发条件的随机接入。
在一些实施例中,所述N是预定义的,或者是网络设备配置的。
在一些实施例中,网络设备在半个无线帧内发送的每个SSB对应相同的位图,所述位图用于指示所述每个SSB关联的RO资源集合共享用于所述第一触发条件的随机接入的RO资源。即网络设备在半帧内发送的所有SSB所关联的RO资源集合共享给同一触发条件的随机接入的RO资源相同。
综上,在一个SSB关联多个RO资源的情况下,网络设备通过位图方式指示该SSB关联的多个RO资源的共享方式,提升了RO共享方式的灵活性,同时有利于避免共享RO资源在不同的随机接入触发条件之间的不均衡问题。
另外,在一个SSB关联一个RO资源的情况下,网络设备考虑该SSB在N个RO配置周期内关联的RO资源进行共享,有利于避免在随机接入无线资源受限时,并且需要共享随机接入无线资源给新增的随机接入触发条件时导致的随机接入冲突问题。
