此处所说明的附图用来提供对本公开的进一步理解,构成本公开的一部分,本公开的示意性实施例及其说明用于解释本公开,并不构成对本公开的不当限定。在附图中:

具体实施方式
在研究过程中注意到:
相关技术中的终端接入机制下,小区内的所有终端必须按照相同的带宽、相同的周期检测接收调度SIB1的PDCCH,而这也就意味着相关技术中的接入方式不能支持小带宽终端的接入,并且不能为不同的终端广播不同的系统信息。
然而,网络中必将会引入低能力终端,这类终端的特点是硬件成本低,待机时间长,终端数量大。相应的,其传输带宽往往很小,例如几个MHz。相关技术中的终端在接入网络时,需要在CORESET#0内检测接收调度SIB1传输的PDCCH,CORESET#0以及对应搜索空间的相关配置通过MIB中的8bit信息进行指示。
但是,考虑到低能力终端支持的带宽较小,可能无法支持CORESET#0的带宽;接入时延的要求也不相同(例如可以允许更长的接入时间);对于系统信息的要求也可能不同,意味着需要独立的SIB1信息。
而在相关技术中的系统中,通过接收相同的SSB只能获得一套CORESET#0以及SS#0的配置,如果指示低能力终端所对应的公共CORESET(common CORESET)以及传输调度SIB1下行控制信道的搜索空间,相关技术中并没有方案能解决这一问题。
基于此,本公开实施例中提供了一种确定及指示接入参数的方案,下面结合附图对本公开的具体实施方式进行说明。
在说明过程中,将分别从UE与基站侧的实施进行说明,然后还将给出二者配合实施的实例以更好地理解本公开实施例中给出的方案的实施。这样的说明方式并不意味着二者必须配合实施、或者必须单独实施,实际上,当 UE与基站分开实施时,其也各自解决UE侧、基站侧的问题,而二者结合使用时,会获得更好的技术效果。
图1为终端侧上确定接入参数的方法实施流程示意图,如图所示,包括:
步骤101、终端检测接收SSB;
步骤102、终端根据所述SSB携带的指示信息,按该终端的能力类型确定用于传输公共下行控制信道的CORESET以及对应的CSS检测周期。
图2为基站侧指示接入参数的方法实施流程示意图,如图所示,包括:
步骤201、基站向终端发送携带有指示信息的SSB,所述SSB携带的指示信息用于供终端根据按该终端的能力类型确定用于传输公共下行控制信道的CORESET以及对应的CSS检测周期;
步骤202、基站发送与所述CORESET以及对应的CSS检测周期对应不同类型终端的PDCCH。
方案中,不同能力终端通过检测接收相同SSB中携带的指示信息,从而确定各自的用于传输公共下行控制信道的CORESET以及对应的公共搜索空间(Common Search Space,CSS)检测周期。
具体的,通过对应CSS的检测周期即可确定CORESET资源集的绝对起始时域位置。
由于终端侧与基站侧的方案具有对应关系,因此下面主要以终端侧的实施为主进行说明,但本领域技术人员根据终端侧的实施是可以推导出基站侧相应的实施方式。
对于终端侧,终端检测接收SSB,并根据其携带的指示信息,确定用于传输公共下行控制信道的CORESET以及对应的CSS检测周期。

具体的,所述表格集合中的CORESET#0带宽,所占符号个数等配置信息与第一类终端对应的表格不同;

具体的,基站在第一类终端对应的CORESET#0以及SS#0中发送调度其对应的SIB1的下行控制信道。
基站在第二类终端对应的CORESET#0以及SS#0中发送调度其对应的 SIB1的下行控制信道。
下面用实例进行说明。
实施例1:
假设系统中存在两类终端,即第一类终端和第二类终端。在本实施例中,第一类终端为正常能力的终端,第二类终端为低能力终端。
终端均通过相同的SSB接入网络,也即接收相同的SSB。接收到SSB中传输的相同MIB信息后,终端对MIB中的CORESET#0以及SS#0配置信息进行解析。根据自身的类型,确定所述MIB中的信息指示的CORESET#0以及SS#0的传输位置。
例如,对于第一类终端,其支持更大的传输带宽,根据SSB以及CORESET#0的子载波间隔(sub-carrier spacing,SCS)组合,确定在第一类型终端对应的CORESET#0和SS#0配置表格集合中确定用于指示CORESET#0和SS#0的表格,并根据MIB中的对应bit(比特)信息决定采用所述表格中的哪一行参数来确定CORESET#0的资源配置以及SS#0传输的时域位置。
对于第二类终端,其支持的传输带宽较小,或者对于接入时延不敏感。在解析完MIB信息后,其对应的表格为从第二类终端对应的CORESET#0和SS#0配置表格中选取。选取的规则可与第一类终端选取表格的规则相同,例如根据SSB以及CORESET#0的子载波间隔的组合来进行选取。
在此例中,假设SSB与CORESET#0的SCS均为15kHz。假设MIB中用于指示CORESET#0资源以及SS#0传输时域位置的指示bit为00000001,其中高4bits用于指示CORESET#0的相关配置,具体的用于指示CORESET#0配置表格中配置参数的行数;低位4bits用于指示SS#0的相关配置,具体的用于指示SS#0配置表格中配置参数的行数。在此实施例中,CORESET#0通过其配置表格中第一行参数的组合确定,SS#0通过其配置表格的第2行参数组合确定。
例如,所述第一类终端对应的CORESET#0以及SS#0的表格如下,其中加粗示意的entry(记录)代表该终端的CORESET#0以及SS#0配置:
表1:第一类终端CORESET#0配置表格

表2:第一类终端SS#0配置表格
Figure PCTCN2021089611-appb-000002
例如所述第二类终端对应的CORESET#0以及SS#0的表格如下,其中加粗的entry代表该终端的CORESET#0以及SS#0配置:
表3:第二类终端CORESET#0配置表格
Figure PCTCN2021089611-appb-000003
表4:第二类终端SS#0配置表格
Figure PCTCN2021089611-appb-000004
图3为不同类型的终端通过相同的MIB信息确定的CORESET#0以及 SS#0配置示意图,不同类型的终端通过相同的MIB信息确定的CORESET#0以及SS#0配置具体如图所示。
实施例2:
如实施例1所示,终端可有更多的类型,并不做任何限定,具体实施中可参考实施例1。
比如更多能力等级的终端,例如比NR lite终端更低能的终端。比如其他类型的终端,例如天地一体化终端,需要检测接收卫星信号等在具体实施中均可参考实施例1。
实施例3:
对于第一类终端对应的表格和第二终端对应的表格,应当保证第一类终端用于调度SIB1的PDCCH和第二类终端用于调度SIB1的PDCCH在资源上没有重叠。
具体的,两者的CORESET#0在资源上完全没有重叠,或者SS#0的传输时域位置完全没有重叠,或者CORESET#0以及SS#0传输的时域位置完全没有重叠。第二类表格的具体参数需要满足第二类终端的相关要求,例如带宽,例如传输时延等等。
需要注意的是,实施时,对于第一类终端和第二类终端对应CORESET#0以及SS#0配置表格的具体参数组合,并不做任何限定。即第一类终端和第二类终端对应表格中各行的参数可以相同也可以不同。
进一步的,实施时,对于第一类终端对应的配置表格和第二类终端对应的配置表格包含的行数也不做限定。
实施例4:
如实施例1-3所述,基站通过MIB中携带的1bit信息,指示可以通过该MIB接入网络的终端类型。
例如,如果对应指示bit为0,则代表只有第一类终端可以通过所述SSB接入网络。如果对应指示bit为1,则代表第一类终端和第二类终端均可以通 过所述SSB接入网络。
基于同一构思,本公开实施例中还提供了一种基站、终端、确定接入参数的装置、指示接入参数的装置、计算机可读存储介质,由于这些设备解决问题的原理与确定接入参数的方法、指示接入参数的方法相似,因此这些设备的实施可以参见方法的实施,重复之处不再赘述。
