本发明涉及信息处理技术领域,尤其涉及一种信息上报方法、信息获取方法、终端、网络设备、芯片、计算机可读存储介质、计算机程序产品以及计算机程序。
背景技术
在无线通信技术的不断演进与助力下,物联网(IOT,Internet Of Things)技术飞速发展。如3GPP组织推动发展的MTC(Machine-Type Communication,机器类型通信)/eMTC(enhanced Machine-Type Communication,增强型机器类型通信),窄带物联网(Narrow Band Internet of Things,NB-IoT)系列标准成为5G massive MTC(5G大型MTC)技术的候选技术标准。这些技术也具有一些应用场景的限制,由于MTC/eMTC,NB-IoT的设计目标是支持一些低数据速率、较高传输时延的应用,因此在一些需要具有相对较高速率的物联网场景,如智能安防中的视频监控、要求相对较低时延工业应用,则不能应用。因此,为了完善5G massive MTC场景的终端体系,需要设计一种即支持中等传输速率、中等时延要求,同时具有较低成本的NR(新无线,New Radio)MTC终端类型,3GPP称这种NR MTC类型的终端为NR-light(轻型)终端。但是,如何让网络获知终端的特征以使得网络做适应性的配置,是一个需要解决的问题。

下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,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,都属于本申请保护的范围。

为了能够更加详尽地了解本发明实施例的特点与技术内容,下面结合附图对本发明实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本发明实施例。
本发明实施例提供了一种信息上报方法,如图2所示,包括:
步骤21:终端向网络设备发送特征信息;
其中,发送所述特征信息的方式为以下至少之一:
通过第一信道或第一信号指示所述终端的特征信息;
在第一信息中携带所述终端的特征信息。
本发明实施例还提供一种信息获取方法,如图3所示,包括:
步骤31:网络设备接收终端发送的特征信息;
其中,接收终端发送的特征信息的方式为以下至少之一:
通过第一信道或第一信号接收所述终端指示的所述特征信息;
接收第一信息中携带的所述特征信息。
本实施例中,所述终端可以为NR-终端,或者,可以为NR-light终端,当然,还可以为IOT中其他类型的终端,这里不做穷举。本实施例提供的方案可以针对能够接入通信网络的全部类型的终端,也就是全部类型的终端都可以向网络设备发送对应的特征信息。
首先针对本实施例中所述特征信息进行说明:
所述特征信息,包括以下至少之一:
所述终端的天线或天线端口的数量;
所述终端支持的传输带宽;
所述终端支持的子载波间隔;
所述终端支持的BWP的数量;
所述终端支持的BWP切换时延;
所述终端支持的最大HARQ进程数量;
所述终端支持的最大传输块TB大小;
所述终端支持的PDCCH监听的相关参数;
所述终端的处理能力的相关参数;
所述终端的信道估计能力的相关参数。
需要指出的是,不同的终端可能包含不同的特征信息,终端根据自己的情况确定所要上报的特征信息具体内容,另外,不同的终端包含的特征信息为前述全部特征信息中的一个或多个。
再进一步地,前述每一种特征信息能够包含的具体内容具体可以参见以下描述:
所述终端的天线或天线端口的数量,可以包括以下至少之一:
终端的天线或天线端口的数量;
终端的上行发射天线或天线端口的数量;
终端的下行接收天线或天线端口的数量;
举例来说,不同的NR-light终端具备的天线或天线端口的数量可能为1、2、4。
上述上行发射天线或天线端口的数量,与下行接收天线或天线端口的数量可以相同也可以不同。
本实施例提供的方案中,如果上行与下行天线或天线端口的数量相同,那么可以仅上报天线或天线端口的数量,也就是网络侧可以默认终端的上行以及下行天线或天线端口的数量为相同的。
如果不相同,那么终端可以分别上报上行天线或天线端口的数量,以及下行接收天线或天线端口的数量。
比如,针对某些特殊应该场景的终端支持的上行发射天线或天线端口的数量与下行接收天线或天线端口的数量可以不同,例如这些终端主要用于支持上行业务,如视频监控,上行传输数据的速率需求远大于下行下载数据的需求,因此可以支持较多的上行天线数目,而支持较少的下行接收天线数目,如上行4天线,下行2接收天线。
终端支持的传输带宽,可以包括以下至少之一:
终端支持的传输带宽;
终端支持的上行传输带宽;
终端支持的下行传输带宽。
也就是说,终端可以上报其支持的传输带宽,此时网络设备可以认为终端的上行以及下行传输带宽为相同的。
另外,如果终端的上行传输带宽与下行传输带宽不同,那么终端的特征信息中可以分别包含有终端支持的上行传输带宽以及下行传输带宽。
又或者,针对特定子载波间隔,终端可支持的传输带宽/上行传输带宽/下行传输带宽中至少之一。
NR-light可以支持较窄的传输带宽,如5MHz,10MHz或20MHz。
类似地,有些终端可以支持不同的上下行带宽,那么终端可以上报的为其支持的上行带宽以及下行带宽,比如下行10MHz,上行20MHz。
终端可支持的子载波间隔,可以为:所述终端能够支持的子载波间隔,这里可以不区分信道,以终端为单位。又或者,可以为终端可支持的同步信道和/或数据信道的子载波间隔。也就是说,同步信道对应的子载波间隔可以与数据信道的子载波间隔相同或不同,如果相同的时候,可以不做区分仅上报终端能够支持的子载波间隔;如果两者不同,那么可以上报终端支持的同步信道以及数据信道的子载波间隔,又或者,仅上报其中一个,这里不再进行穷举。
终端可支持的带宽部分(BWP,BandWidth Part)的数目,可以包括以下至少之一:
终端可支持的具有不同带宽的BWP的数目;其中,如果仅支持一种带宽,那么可以仅上报终端可支持的带宽和/或BWP的数量;如果支持多种带宽,那么可以分别上报多种带宽和/或终端支持的每一个带宽的BWP的数量。
终端可支持的具有不同的子载波间隔的BWP的数目;其中,如果仅具有一种子载波间隔,那么终端可以上报支持的子载波间隔和/或BWP的数量。如果支持多种子载波间隔,那么可以分别上报终端可支持的每一个子载波间隔和/或其对应的BWP数量。
终端可支持的UL(上行链路,UpLink)BWP的数目;也就是说,如果终端支持的UL以及DL的BWP的数量不同的情况下,那么终端可以仅上报其支持的UL BWP的数量。
终端可支持的具有不同带宽的UL BWP的数目;可以理解为,终端可以支持多种带宽的UL BWP,或者,支持的多种带宽的UL BWP及不同带宽的UL BWP的数量,或者,可以仅为终端支持的多种带宽的UL BWP所对应的UL BWP的数量。
终端可支持的具有不同的子载波间隔的UL BWP的数目;可以理解为,终端可以支持多种子载波间隔,那么分别上报终端支持的不同子载波间隔和/或不同子载波间隔对应的UL BWP的数量。
终端可支持的BWP的带宽大小和/或子载波间隔;终端可以将自身支持的子载波间隔上报给网络设备,如果终端支持一种子载波间隔,那么就单独上报一个,如果支持多个那么需要上报多个。另外,如果每一个子载波间隔支持的BWP带宽大小相同,可以仅上报一个BWP带宽,如果不同的子载波间隔对应的BWP带宽大小不同,那么需要上报终端支持的多种子载波间隔,以及每一个子载波间隔对应的BWP带宽大小。再进一步地,如果终端支持的多个子载波间隔中,存在至少部分子载波间隔对应多种BWP带宽大小,那么可以还包含有每一个子载波间隔对应的BWP带宽数量及其对应的大小。
终端可支持的DL(下行链路,DownLink)BWP的数目;也就是说,如果终端支持的UL以及DL的BWP的数量不同的情况下,那么终端可以仅上报其支持的DL BWP的数量。
终端可支持的具有不同带宽的DL BWP的数目;可以理解为,终端可以支持多种带宽,那么分别上报不同DL的BWP带宽和/或不同带宽的DL BWP的数量。
终端可支持的具有不同的子载波间隔的DL BWP的数目;可以理解为,终端可以支持多种子载波间隔,那么分别上报终端支持的下行的不同子载波间隔和/或不同子载波间隔对应的DL BWP的数量。
终端支持的BWP(或BWP配置)的数目越多或者支持的BWP带宽的数目越多,终端的设计越复杂,如针对不同的带宽的BWP,需要支持不同带宽大小的射频和/或基带滤波器。因此,对于某些简单应用场景的终端,可以支持有限的BWP数目或有限的BWP带宽大小。
需要理解的是,前述终端支持的BWP的数量的具体内容,可以包括前述一个或多个,不同的终端可以根据自身的实际情况进行上报。举例来说,终端可以上报终端可支持的UL BWP的数目为2个,此时如果不上报DL BWP的数量,那么可以默认为UL以及DL的BWP数量相同也为2个。或者,终端的特征信息中可以包括所述终端可以支持的UL BWP数量为2个,DL BWP的数量为4个。这里不做穷举。
所述终端可支持的BWP切换的时延,可以包括:
终端可支持的BWP切换的时延;
和/或,终端可支持的UL BWP切换的时延;
和/或,终端可支持的DL BWP切换的时延。
BWP切换可能涉及终端的射频参数,如带宽大小,频率位置,或终端的基带参数的调整,如不同的PDCCH search space(搜索空间)的配置,不同应用的NR-light终端可以支持不同的BWP切换时延。一些对于时延不敏感的场景,可以支持较大的BWP切换时延,用于放松UE的设计需求,进而降低终端的器件成本。
同样的,如果终端可以支持的UL BWP切换的时延、与DL BWP切换的时延相同,可以仅上报所述终端可支持的BWP切换的时延;又或者,可以仅上报UL或DL BWP切换的时延。如果终端可支持的UL BWP切换的时延与DL BWP切换的时延不同,那么特征信息中可以既包含ULBWP切换的时延,又包含DL BWP切换的时延。
所述终端可支持的最大HARQ(混合自动重传请求,Hybrid Automatic Repeat reQuest)进程数目,可以为以下至少之一:
终端可支持的最大HARQ进程数目;
终端可支持的最大UL HARQ进程数目;
终端可支持的最大DL HARQ进程数目。
需要指出的是,HARQ进程数目会影响终端的数据传输的峰值速率和传输时延,HARQ进程数目越多,所述峰值速率越高,所述传输时延越低,但HARQ进程数目越多,也会增大终端的芯片面积,进而增大终端成本。
对于数据传输时延不敏感或数据速率要求较低的场景,可以支持较少的HARQ进程数目,以降低终端的成本。
同样的,如果终端可以支持的最大UL HARQ进程数目、与最大DL HARQ进程数目相同,可以仅上报所述终端可支持的最大UL HARQ进程数目;又或者,可以仅上报最大HARQ进程数目。如果终端可支持的最大UL HARQ进程数目与最大DL HARQ进程数目不同,那么特征信息中可以既包含最大UL HARQ进程数目,又包含最大DL HARQ进程数目。
终端可支持的最大TB(传输块,Transport Block)size(大小),可以包括以下至少之一:
终端可支持的最大TB大小;
终端可支持的最大UL TB size;
终端可支持的最大DL TB size。
同样的,如果终端可以支持的最大UL TB大小、与最大DL TB大小相同,可以仅上报所述终端可支持的最大UL TB大小;又或者,可以仅上报最大TB大小。
如果终端可支持的最大UL TB大小与最大DL TB大小不同,那么特征信息中可以既包含最大UL TB大小,又包含最大DL TB大小。
所述终端可支持的PDCCH(物理下行控制信道,Physical Downlink Control CHannel)监听相关参数,如下述至少其中之一:
单位时间内PDCCH盲检的数目;其中,所述单位时间可以为根据实际情况设置的时长,比如,可以为1ms或1个时隙,当然还可以为更长或更短,这里不再穷举。
支持的相邻PDCCH监听时刻的最小间隔;
支持的PDCCH聚合等级的种类;比如,PDCCH的聚合等级可以为1、2、4、8个CCE,终端 根据自身的情况选取自身能够支持的其中之一。
支持每一种聚合能级的PDCCH候选位置的数目;
支持的PDCCH CORESET(控制资源集合)配置的数目;
支持的PDCCH search space set(搜索空间集合)的数目。
举例来说,有一些终端可以支持一个ms内44次PDCCH盲检尝试数目,但有一些终端可以仅支持22次PDCCH盲检尝试数目,进而降低终端的处理器要求和成本。
终端的处理能力相关的参数,例如终端处理控制信道或数据信道相关的能力;如PDCCH与PDSCH(物理下行共享信道,Physical Downlink Share CHannel)/PUSCH(物理上行共享信道,Physical Uplink Share CHannel)之间的定时差;或PDSCH与PUSCH之间的定时差。例如,有一些终端可以支持较长的前述种类的定时差,进而降低终端的处理器要求和成本。当然,所述终端的处理能力相关参数还可以存在其他类型,这里不再进行穷举,相关技术中能够用于指示终端的处理能力相关参数均可以包含于本申请实施例中。
所述终端的信道估计能力的相关参数。比如,终端在一个时间单位之内(比如,1ms内,或者1个时隙内)不重叠的CCE的个数。
结合前述,不同的终端上报的特征信息可以不同或相同,均根据自身情况来确定,比如,终端A所要上报的特征信息,可以包括:支持的上行发射天线的数量为2,支持的下行接收天线的数量为4;支持的传输带宽为5MHz;支持的BWP的数量为2个等等。终端B所要上报的特征信息可以包括:支持的天线的数量为4;支持的上行传输带宽为5MHz,支持的下行传输带宽为10MHz;支持的PDCCH聚合类型的种类为2种等等。本实施例中不再进行穷举。
需要说明是,前述上报的终端特征仅为示例,对具体的特征种类与数目不构成限定。
基于前述特征信息的说明,下面结合多种示例对终端如何向网络设备指示自身的特征信息的具体处理进行说明:
示例1、通过PRACH的资源组,来隐式的指示所述网络设备对应的特征信息。也就是可以采用PRACH资源分组来指示不同的终端特征分组。网络可以配置多组PRACH资源,每一组资源分组对应一组终端特性。
具体如下:
所述终端通过在随机接入信道PRACH对应的第一资源组上传输PRACH,指示所述特征信息为所述第一资源组所对应的第一特征信息组;
其中,所述第一特征信息组中包含有至少一个所述特征信息;
所述PRACH对应的第一资源组为所述PRACH所对应的至少一个资源组中之一;所述PRACH所对应的至少一个资源组中不同的资源组对应不同的特征信息组;其中,每一个特征信息组中均包含至少一个所述特征信息,且不同的特征信息组包含的特征信息至少部分不同。
相应的,所述网络设备在随机接入信道PRACH对应的第一资源组上接收所述终端传输的PRACH;所述网络设备根据所述PRACH对应的所述第一资源组确定所述特征信息为对应的第一特征信息组。
每一个特征信息组包含有前述特征信息中的一个或多个。可以为全部的前述特征信息,又或者,可以为其中部分特征信息。
进一步地,所述终端根据第一配置信息,确定所述PRACH所对应的至少一个资源组中不同的资源组对应不同的特征信息组;
其中,所述第一配置信息为预设的,或者为网络设备发送给所述终端的。
其中,网络设备发送给终端可以通过系统信息,比如SIB、MIB等配置给终端;或者,通过MAC CE发送给终端;再或者,可以通过RRC信令配置给终端,这里不再穷举。
需要理解的是,所述第一配置信息在网络设备侧也同样保存,可以为根据协议预设在网络设备侧的,或者,可以网络设备根据协议生成的,如果是网络设备生成的,那么网络设备需要向所述终端发所述第一配置信息。
所述第一配置信息中,具体可以包括:至少一个PRACH的资源组,每一个PRACH对应的资源组所对应的特征信息组。
比如,可以预定义或网络预配置多组终端特征中的每一组终端特性的具体特征的定义。如共预定义三组终端特征信息:
特征信息组1、支持2接收天线,支持5MHz的终端带宽;支持2种BWP的配置;支持4个HARQ进程数。
特征信息组2、支持4接收天线,支持20MHz的终端带宽;支持4种BWP的配置;支持8个 HARQ进程数。
特征信息组3、支持4接收天线,支持10MHz的下行接收带宽和上行20MHz的发射带宽;支持2种BWP的配置;支持4个HARQ进程数。
那么在第一配置信息中,可以为资源组1对应特征信息组1,资源组2对应特征信息组2,资源组3对应特征信息组3。
前述第一资源组可以为一个或多个资源组中的一个,这里只是将其称为第一资源组。
如果第一配置信息中仅包含一个资源组及其对应的特征信息组,那么不需要进行选取,直接将该第一配置信息中指示的资源组作为第一资源组。
如果第一配置信息中包含两个或更多资源组,那么终端的处理还可以包括:
根据自身的特征信息,从所述多个资源组中选取与所要发送的特征信息匹配的第一资源组;然后,在所述第一资源组中传输PRACH;
相应的,网络设备在第一资源组对应的资源上接收到终端发来的PRACH,那么网络设备可以根据所述第一资源组确定所述终端的第一特征信息组;进而,所述网络设备根据所述第一特征信息组确定所述终端上报的至少一个特征信息。
再具体来说,所述多个资源组中可能并没有包含所述终端所要上报的全部的特征信息,那么就从多个资源组中选取与终端所要上报的全部特征信息中至少部分匹配的第一资源组。
结合前述例子进一步说明,如果终端所要上报的特征信息为特征信息组2,那么可以将特征信息组2对应的资源组2作为前述第一资源组;然后终端在所述第一资源组传输PRACH。网络设备在第一资源组接收到PRACH,那么可以确定终端上报了前述特征信息组2,然后基于特征信息组2的内容,确定所述终端的特征信息。
示例2、通过Preamble(前导码),来隐式的指示所述网络设备对应的特征信息。也就是说,可以采用preamble分组来指示不同的终端特征分组。网络可以配置多组preamble,每一组preamble分组对应一组终端特性。
具体如下:
所述终端发起随机接入的过程中,所述终端通过向所述网络设备发送第一前导码Preamble组,指示所述终端的特征信息为所述第一Preamble对应的第二特征信息组;
其中,所述第二特征信息组中包含有至少一个所述特征信息。
其中,所述第一Preamble组为至少一个Preamble组中之一;所述至少一个Preamble组中不同的Preamble组对应不同的特征信息组;其中,每一个特征信息组中均包含至少一个所述特征信息,且不同的特征信息组包含的特征信息至少部分不同。
相应的,在随机接入的过程中,所述网络设备接收所述终端发送的第一前导码Preamble组;所述网络设备根据所述第一Preamble确定终端对应的第二特征信息组。
所述终端根据第二配置信息,确定所述至少一个Preamble组中不同的Preamble组对应不同的特征信息组;
其中,所述第二配置信息为预设的,或者为网络设备发送给所述终端的。
其中,网络设备发送给终端可以通过系统信息,比如SIB、MIB等配置给终端;或者,通过MAC CE发送给终端;再或者,可以通过RRC信令配置给终端,这里不再穷举。
需要理解的是,所述第二配置信息在网络设备侧也同样保存,可以为根据协议预设在网络设备侧的,或者,可以网络设备根据协议生成的,如果是网络设备生成的,那么网络设备需要向所述终端发所述第二配置信息。
所述第二配置信息中,具体可以包括:至少一个Preamble组,每一个Preamble组对应的特征信息组。
可以预定义或网络预配置多组终端特征中的每一组终端特性的具体特征的定义。如共预定义三组终端特征:
第一组终端特征为支持1接收天线,支持5MHz的终端带宽;支持2种BWP的配置;支持4个HARQ进程数。
第二组终端特征为支持2接收天线,支持20MHz的终端带宽;支持4种BWP的配置;支持8个HARQ进程数。
第三组终端特征为支持2接收天线,支持10MHz的下行接收带宽和上行20MHz的发射带宽;支持2种BWP的配置;支持4个HARQ进程数。
例如,可以通过第二配置信息的内容确定以下:
所述终端可用的preamble集合为[0 35],则可采用三组preamble子集分别对应前述三组终端特征,例如preamble集合为[0 11]对应第一组终端特征,preamble集合为[12 23]对应第二组终端特征,preamble集合为[24 35]对应第三组终端特征。
进而,前述第一Preamble组可以为一个或多个Preamble组中的一个,这里只是将其称为第一Preamble组。
如果第二配置信息中仅包含一个Preamble组及其对应的特征信息组,那么不需要进行选取,直接将该第二配置信息中指示的Preamble组作为第一Preamble组。
如果第二配置信息中包含两个或更多Preamble组,那么终端的处理还可以包括:
根据自身的特征信息,从所述多个Preamble组中选取与所要发送的特征信息匹配的第一Preamble组;然后,传输Preamble组;相应的,网络设备接收到终端发来的第一Preamble组,那么网络设备可以根据所述第一Preamble组确定所述终端的第二特征信息组;进而,所述网络设备能够根据所述第二特征信息组确定所述终端上报的至少一个特征信息。
再具体来说,所述多个Preamble组中可能并没有包含所述终端所要上报的全部的特征信息,那么就从多个Preamble组中选取与终端所要上报的全部特征信息中至少部分匹配的第一Preamble组。
也就是说,终端在发起随时接入时,分别在对应该组终端特征的preamble集合(或Preamble组)选择preamble。结合所述preamble分组以及所述preamble分组对应的终端特征,网络在接收的preamble时即可判断发起随机接入的终端特征,进而对终端后续的数据传输进行合理的资源分配。
本示例中,发送第一Preamble组的方式可以为:
采用共享的随机接入时机RO承载所述第一前导码Preamble组,或者,采用独立的RO承载所述第一前导码Preamble组。
需要理解的是,前导码在RO中承载(或传输),一个RO上可以有64个前导。
相应的,网络设备所述接收第一前导码Preamble组的方式,为:接收采用共享的随机接入时机RO承载的所述第一前导码Preamble组,或者,接收采用独立的RO承载的所述第一前导码Preamble组。
也就是说,用于指示终端特征的preamble可以采用与正常NR终端共享随机接入时机(RO,RACH occasion)的方式,也可以采用单独配置独立的RO的方式。
如果单独配置独立的RO的方式,那么可以根据独立配置的RO进行传输,这里不再赘述。
本示例中主要针对共享RO的方式进行说明:
在采用共享的RO承载所述第一Preamble组的情况下,
所述方法还包括:
所述终端接收第三配置信息;
其中,所述第三配置信息中包含:网络设备为终端配置的由用于竞争随机接入CBRA的至少一个Preamble所组成的集合;以及用于指示终端的特征信息的至少一个Preamble组。
相应的,所述网络设备向所述终端发送第三配置信息。
这里,所述第三配置信息,可以由RRC信令携带、MAC CE携带,或者可以由系统广播信息携带。
所述用于竞争随机接入CBRA的至少一个Preamble所组成的集合,可以理解为四步随机接入所占用的Preamble所组成的集合,
比如,参见图4,对于共享RO的方式,前述上报终端特征的preamble集合可以在传统用于配置正常NR终端进行CBRA(contention based random access,竞争随机接入)的所占用的preamble集合之外配置(也就是四步随机接入所占用的Preamble集合之外配置),可以靠近正常NR终端进行CBRA(Contention Based Random Access,竞争随机接入)所占用的preamble集合且在其之后进行配置上报终端特征的preamble集合。
另外,在前述的基础上,所述第三配置信息中,还包括:网络设备为终端配置的由用于两步随机接入的至少一个Preamble所组成的集合。
比如,参见图5,若系统中还配置了2-step RACH且为2-step RACH分配的preamble与正常NR终端共享RO,则前述上报终端特征的preamble集合可以在传统用于配置正常NR终端进行CBRA的所占用的preamble集合(也就是用于四步随机接入的至少一个Preamble所组成的集合)以及用于两步随机接入的至少一个Preamble所组成的集合之外配置,例如可以靠近2-step RACH分配的preamble集合在其之后进行配置用于指示终端的特征信息的至少一个Preamble组。
进一步地,用于指示终端特征的preamble与正常NR终端共享的RO可以是正常NR终端使用 的所有RO的一部分。那么所述方法还包括:
所述终端接收第四配置信息;其中,所述第四配置信息中包含:能够用于承载所述第一前导码Preamble组的至少一个RO。
相应的,所述网络设备向所述终端发送第四配置信息;其中,所述第四配置信息中包含:能够用于承载所述第一前导码Preamble组的至少一个RO。
也就是,所述网络设备可以发送第四配置信令指示在正常NR终端使用的所有RO中哪些RO还用于承载指示终端特征的preamble。
需要指出的是,第四配置信息可以与第三配置信息在同一个信令中携带,比如,可以为同一个信令中的两个IE中包含,当然,第四配置信息也可以与第三配置信息分为两条信令发送,这里不进行限定。
示例3、与前述示例1、2不同在于,本示例可以为通过第一信息显式的向网络设备指示对应的特征信息。
具体的:
一种方式中,所述终端在第一信息中携带所述终端的至少一个特征信息。
也就是说,通过列举的方式,在第一信息中携带有所述终端所要上报的全部的特征信息,比如,可以包括:支持的上行发射天线的数量为2,支持的下行接收天线的数量为4;支持的传输带宽为5MHz;支持的BWP的数量为2个等等。那么相应的,网络设备直接通过接收到的第一信息获取终端上报的特征信息。
和/或,再一种方式中,所述终端在所述第一信息中携带特征信息组的标识;其中,所述特征信息组的标识用于指示特征信息组所包含的至少一个特征信息。相应的,所述网络设备接收所述终端在所述第一信息中携带的特征信息组的标识。
也就是说,在第一信息中可以仅包含一个标识,通过该标识可以上报对应的特征信息组;相应的,网络设备可以根据第一信息中携带的所述标识,确定终端上报的特征信息组,进而确定包含的至少一个特征信息。
所述第一信息,为以下之一:
四步随机接入的MSG3的PUSCH、二步随机接入中的MSG A的PUSCH、RRC信令、MAC CE信令。
再进一步地,本方式中,所述特征信息组的标识所对应的至少一个特征信息可以为终端以及网络设备均预配置的。
也就是,所述终端以及所述网络设备可以是预先将终端特征分组。所述终端上报终端特征的组标识。
进一步地,前述两种方式可以单一使用,也可以结合使用,比如,如果特征信息组并未包含全部的特征信息,那么终端可以通过特征信息组的标识上报其中部分特征信息,将剩余的特征信息分别上报。
比如,终端所要上报的特征信息由10个,其中存在6个可以具备对应的特征信息组,那么在第一信息中携带6个特征信息对应的特征信息组的标识;剩余的4个特征信息可以在第一信息中携带并上报。
举例来说,可以在第一信息中携带特征信息组的标识1,还携带终端特征的各个参数,如支持的终端天线数目、端口数目、终端带宽、支持的BWP数目等。
前述示例1、2、3可以单独使用,在一些可能的实施方式中,前述上报终端特征的多种方式也可以结合使用。例如可以先采用PRACH信道或Preamble上报部分终端特征,如支持的天线数目/端口数目;再通过RRC信令也就是第一信息上报包括如支持的带宽、BWP数目、HARQ进程数目等特征的一个或多个特性。
举例来说,示例1、3可以结合使用,终端将全部要上报的特征信息中能够与第一配置信息中包含的PRACH资源组所对应的特征信息组的特征信息,作为第一特征信息组,基于第一特征信息组所对应的PRACH的第一资源组指示网络设备对应的第一特征信息组,使得网络设备根据资源组确定特征信息组,进而确定终端上报的特征信息。然后,终端将除第一特征信息组之外的所要上报的特征信息的剩余特征信息(可以称为第二部分特征信息),通过第一信息逐个上报。
还可以包括:终端将第二部分特征信息,再与预设的特征信息组标识及其对应的至少一个特征信息进行匹配,可以将第二部分特征信息中的一部分通过第一信息携带其对应的特征信息组的标识进行上报;最后再通过第一信息携带第二部分特征信息中的另一部分特征信息。
再举例来说,示例2、3可以结合使用,
终端将全部要上报的特征信息中能够与第二配置信息中包含的Preamble组所对应的特征信息组的特征信息,作为特征信息组A,基于特征信息组A所对应的第一Preamble组指示网络设备对应的特征信息组A,使得网络设备根据第一Preamble组确定特征信息组A及其对应的至少一个特征信息。然后,终端将除特征信息组A之外的所要上报的特征信息的剩余特征信息(可以称为第三部分特征信息),通过第一信息逐个上报。
还可以包括:终端将第三部分特征信息,再与预设的特征信息组标识及其对应的至少一个特征信息进行匹配,可以将第三部分特征信息中的一部分通过第一信息携带其对应的特征信息组的标识进行上报;最后再通过第一信息携带第三部分特征信息中的另一部分特征信息。
又或者,示例1、2、3可以进一步结合,比如,终端确定所要上报的特征信息;然后根据第一配置信息确定PRACH资源组对应的特征信息组中所包含的特征信息组1,根据第二配置信息确定Preamble组对应的特征信息中所包含的特征信息组2(特征信息组1、2可以存在重合不同,但是如果全部重合,那么可以仅选取一种方式上报,只要存在部分特征信息不同,就可以两者均采用);
所述终端基于特征信息组1确定对应的PRACH资源组1,通过PRACH资源组1进行PRACH传输;相应的,网络设备在PRACH资源组1接收到PRACH后,确定对应的特征信息组为特征信息组1,然后获取终端对应的特征信息;
所述终端基于特征信息组2确定对应的Preamble组2,(在随机接入过程中)所述终端在RO上传输Preamble组2;相应的,网络设备接收到Preamble组2后,确定其对应的为特征信息组2,然后网络设备获取到终端对应的特征信息。
然后,终端将所要上报的特征信息中,除特征信息组1、2之外的剩余特征信息,通过第一信息(比如RRC信令)上报给网络设备;相应的,网络设备通过RRC信令获取到对应的特征信息。
最后,本实施例还提供一种方式,针对不同类型的终端,比如NR-Light终端,还可以通过Preamble指示对应的相关信息,其中,所述相关信息可以为除前述特征信息之外的信息。比如,所述相关信息可以为终端的能力、类型、或者能力等级、类别等等,仅作为示例进行说明不作为对相关信息的限定,实际上还可以存在其他的相关信息,本实施例中不做穷举。
也就是,还可以通过Preamble(前导码),来隐式的指示所述终端的其他相关信息。
具体如下:
所述终端发起随机接入的过程中,所述终端通过向所述网络设备发送第二前导码Preamble/或第二Preamble组,指示所述终端的特征信息为对应的至少一个相关信息。
其中,所述第二Preamble/或第二Preamble组为至少一个Preamble或Preamble组中之一;所述至少一个Preamble组中不同的Preamble组对应的相关信息至少部分不同,或者,不同的Preamble对应的相关信息至少部分不同。
相应的,在随机接入的过程中,所述网络设备接收所述终端发送的第二前导码Preamble/或第二Preamble组;所述网络设备根据所述第二前导码Preamble/或第二Preamble组确定终端对应的至少一个相关信息。
所述终端根据第五配置信息,确定所述至少一个Preamble组中不同的Preamble组对应不同的相关信息;或者,确定至少一个Preamble对应的不同的相关信息。
其中,所述第五配置信息为预设的,或者为网络设备发送给所述终端的。
其中,网络设备发送给终端第五配置信息,可以为通过系统信息,比如SIB、MIB等配置给终端;或者,通过MAC CE发送给终端;再或者,可以通过RRC信令配置给终端,这里不再穷举。
需要理解的是,所述第五配置信息在网络设备侧也同样保存,可以为根据协议预设在网络设备侧的,或者,可以网络设备根据协议生成的,如果是网络设备生成的,那么网络设备需要向所述终端发所述第五配置信息。
所述第五配置信息中,具体可以包括:至少一个Preamble组,每一个Preamble组对应的相关信息;或者,至少一个Preamble中每一个Preamble对应的相关信息。
例如,可以通过第五配置信息的内容确定以下:
所述终端可用的preamble集合为[0 35],则可采用三组preamble子集分别对应前述三组相关信息,例如preamble集合为[1 13]对应第一组相关信息,preamble集合为[14 25]对应第二组相关信息,preamble集合为[18 31]对应第三组相关信息。
如果第五配置信息中仅包含一个Preamble组及其对应的相关信息组,那么不需要进行选取,直接将该第五配置信息中指示的Preamble组作为第二Preamble组。
如果第五配置信息中包含两个或更多Preamble组,那么终端的处理还可以包括:
根据所要发送的相关信息,从所述多个Preamble组或多个Preamble中选取与所要发送的相关信息匹配的第二Preamble组或第二Preamble;然后,传输第二Preamble组或第二Preamble;
相应的,网络设备接收到终端发来的第二Preamble组或第二Preamble,那么网络设备可以根据第五配置信息,确定所述第二Preamble组或第二Preamble所对应的所述终端的第二组相关信息;进而,所述网络设备能够根据所述第二组相关信息确定所述终端上报的至少一个相关信息。
发送第二Preamble组或第二Preamble的方式可以为:
采用共享的随机接入时机RO承载所述第二Preamble组或第二Preamble,或者,采用独立的RO承载所述第二Preamble组或第二Preamble。
需要理解的是,前导码在RO中承载(或传输),一个RO上可以有64个前导。
相应的,网络设备所述接收第二Preamble组或第二Preamble的方式,为:接收采用共享的随机接入时机RO承载的所述第二Preamble组或第二Preamble,或者,接收采用独立的RO承载的所述第二Preamble组或第二Preamble。
也就是说,用于指示相关信息的preamble可以采用与正常NR终端共享随机接入时机(RO,RACH occasion)的方式,也可以采用单独配置独立的RO的方式。
如果单独配置独立的RO的方式,那么可以根据独立配置的RO进行传输,这里不再赘述。
本示例中主要针对共享RO的方式进行说明:
在采用共享的RO承载所述第二Preamble组或第二Preamble的情况下,
所述方法还包括:
所述终端接收第六配置信息;
其中,所述第六配置信息中包含:用于指示相关信息的至少一个Preamble组或Preamble。
还需要理解的是,所述第六配置信息中还可以包括前述示例2中第三配置信息中包含的至少部分内容,比如,还可以包括:
网络设备为终端配置的由用于竞争随机接入CBRA的至少一个Preamble所组成的集合,和/或用于指示终端的特征信息的至少一个Preamble组。这里不再进行赘述。
相应的,所述网络设备向所述终端发送第六配置信息。
这里,所述第六配置信息,可以由RRC信令携带、MAC CE携带,或者可以由系统广播信息携带。
另外,在前述的基础上,所述第六配置信息中,还包括:网络设备为终端配置的由用于两步随机接入的至少一个Preamble所组成的集合。
进一步地,用于指示终端的相关信息的preamble与正常NR终端共享的RO可以是正常NR终端使用的所有RO的一部分。那么所述方法还包括:
所述终端接收第七配置信息;其中,所述第七配置信息中包含:能够用于承载所述第二前导码Preamble组/或第二Preamble的至少一个RO。
需要指出的是,第七配置信息可以与第六配置信息在同一个信令中携带,比如,可以为同一个信令中的两个IE中包含,当然,第七配置信息也可以与第六配置信息分为两条信令发送,这里不进行限定。
可见,通过采用上述方案,就能够使得终端向网络设备上报对应的特征信息。如此,网络设备就能够获取到终端对应的特征信息,进而便于网络设备基于终端的特征信息为终端做相应的配置或相应的操作,从而保证了终端在网络中执行符合自身特征的操作,使得终端在通信系统中正常工作。

需要说明是,前述上报的终端特征仅为示例,对具体的特征种类与数目不构成限定。
基于前述特征信息的说明,下面结合多种示例对终端如何向网络设备指示自身的特征信息的具体处理进行说明:
示例1、通过PRACH的资源组,来隐式的指示所述网络设备对应的特征信息。也就是可以采用PRACH资源分组来指示不同的终端特征分组。网络可以配置多组PRACH资源,每一组资源分组对应一组终端特性。
具体如下:
所述终端的第一通信单元61,通过在随机接入信道PRACH对应的第一资源组上传输PRACH,指示所述特征信息为所述第一资源组所对应的第一特征信息组;
其中,所述第一特征信息组中包含有至少一个所述特征信息;

每一个特征信息组包含有前述特征信息中的一个或多个。可以为全部的前述特征信息,又或者,可以为其中部分特征信息。
进一步地,所述终端还包括第一处理单元62,根据第一配置信息,确定所述PRACH所对应的至少一个资源组中不同的资源组对应不同的特征信息组;
其中,所述第一配置信息为预设的,或者为网络设备发送给所述终端的。
示例2、通过Preamble(前导码),来隐式的指示所述网络设备对应的特征信息。也就是说,可以采用preamble分组来指示不同的终端特征分组。网络可以配置多组preamble,每一组preamble分组对应一组终端特性。
具体如下:
所述终端的第一通信单元61,发起随机接入的过程中,通过向所述网络设备发送第一前导码Preamble组,指示所述终端的特征信息为所述第一Preamble对应的第二特征信息组;
其中,所述第二特征信息组中包含有至少一个所述特征信息。
其中,所述第一Preamble组为至少一个Preamble组中之一;所述至少一个Preamble组中不同的Preamble组对应不同的特征信息组;其中,每一个特征信息组中均包含至少一个所述特征信息,且不同的特征信息组包含的特征信息至少部分不同。
相应的,在随机接入的过程中,所述网络设备的第二通信单元71,接收所述终端发送的第一前导码Preamble组;所述网络设备的第二处理单元72根据所述第一Preamble确定终端对应的第二特征信息组;

所述第二配置信息中,具体可以包括:至少一个Preamble组,每一个Preamble组对应的资源组所对应的特征信息组。
本示例中,第一通信单元61发送第一Preamble组的方式可以为:
采用共享的随机接入时机RO承载所述第一前导码Preamble组,或者,采用独立的RO承载所述 第一前导码Preamble组。

本示例中主要针对共享RO的方式进行说明:
在采用共享的RO承载所述第一Preamble组的情况下,
所述终端的第一通信单元61接收第三配置信息;
其中,所述第三配置信息中包含:网络设备为终端配置的由用于竞争随机接入CBRA的至少一个Preamble所组成的集合;以及用于指示终端的特征信息的至少一个Preamble组。

进一步地,用于指示终端特征的preamble与正常NR终端共享的RO可以是正常NR终端使用的所有RO的一部分。那么所述终端的第一通信单元61接收第四配置信息;其中,所述第四配置信息中包含:能够用于承载所述第一前导码Preamble组的至少一个RO。
相应的,所述网络设备的第二通信单元71向所述终端发送第四配置信息;其中,所述第四配置信息中包含:能够用于承载所述第一前导码Preamble组的至少一个RO。
示例3、与前述示例1、2不同在于,本示例可以为通过第一信息显式的向网络设备指示对应的特征信息。
具体的:
一种方式中,所述终端的第一通信单元61在第一信息中携带所述终端的至少一个特征信息。
和/或,再一种方式中,所述终端的第一通信单元61在所述第一信息中携带特征信息组的标识;其中,所述特征信息组的标识用于指示特征信息组所包含的至少一个特征信息。相应的,所述网络设备接收所述终端在所述第一信息中携带的特征信息组的标识。
也就是说,在第一信息中可以仅包含一个标识,通过该标识可以上报对应的特征信息组;相应的,网络设备的第二处理单元72可以根据第一信息中携带的所述标识,确定终端上报的特征信息组,进而确定包含的至少一个特征信息。
所述第一信息,为以下之一:
四步随机接入的MSG3的PUSCH、二步随机接入中的MSG A的PUSCH、RRC信令、MAC CE信令。
可见,通过采用上述方案,就能够使得终端向网络设备上报对应的特征信息。如此,网络设备就能够获取到终端对应的特征信息,进而便于网络设备基于终端的特征信息为终端做相应的配置或相应的操作,从而保证了终端在网络中执行符合自身特征的操作,使得终端在通信系统中正常工作。
最后,本实施例还提供一种方式,针对不同类型的终端,比如NR-Light终端,还可以通过Preamble指示对应的相关信息,其中,所述相关信息可以为除前述特征信息之外的信息。比如,所述相关信息可以为终端的能力、类型、或者能力等级、类别等等,仅作为示例进行说明不作为对相关信息的限定,实际上还可以存在其他的相关信息,本实施例中不做穷举。
也就是,还可以通过Preamble(前导码),来隐式的指示所述终端的其他相关信息。
具体如下:
所述终端的第一通信单元,发起随机接入的过程中,通过向所述网络设备发送第二前导码Preamble/或第二Preamble组,指示所述终端的特征信息为对应的至少一个相关信息。
其中,所述第二Preamble/或第二Preamble组为至少一个Preamble或Preamble组中之一;所述至少一个Preamble组中不同的Preamble组对应的相关信息至少部分不同,或者,不同的Preamble对应的相关信息至少部分不同。
相应的,在随机接入的过程中,所述网络设备的第二通信单元接收所述终端发送的第二前导码Preamble/或第二Preamble组;根据所述第二前导码Preamble/或第二Preamble组确定终端对应的至少一个相关信息。
所述终端根据第五配置信息,确定所述至少一个Preamble组中不同的Preamble组对应不同的相关信息;或者,确定至少一个Preamble对应的不同的相关信息。
其中,所述第五配置信息为预设的,或者为网络设备发送给所述终端的。
所述第五配置信息中,具体可以包括:至少一个Preamble组,每一个Preamble组对应的相关信息;或者,至少一个Preamble中每一个Preamble对应的相关信息。
发送第二Preamble组或第二Preamble的方式可以为:
所述第一通信单元,采用共享的随机接入时机RO承载所述第二Preamble组或第二Preamble,或者,采用独立的RO承载所述第二Preamble组或第二Preamble。
相应的,网络设备的第二通信单元,接收采用共享的随机接入时机RO承载的所述第二Preamble组或第二Preamble,或者,接收采用独立的RO承载的所述第二Preamble组或第二Preamble。
