图1是根据一示例性实施例示出的一种通信系统的框图。请参考图1,该移动通信系统可以包括:接入网设备10和终端20。
接入网设备10部署在无线接入网中用以为终端20提供无线接入功能。接入网设备可以是基站(Base Station,BS)。接入网设备10可以经由一个或多个天线与终端20进行无线通信。接入网设备10可以为其所在地理区域提供通信覆盖。所述基站可以包括宏基站,微基站,中继站,接入点等不同类型。在一些实施例中,基站可以被本领域技术人员称为基站收发机、无线基站、接入点、无线收发机、基本服务集(Basic Service Set,BSS)、扩展服务集(Extended Service Set,ESS)、节点B(NodeB)、演进的节点B(evolved NodeB,eNB或eNodeB)或者其它一些适当的术语。示例性地,在5G系统中,基站被称为gNB。为方便描述,本申请实施例中,上述为终端20提供无线通信功能的装置统称为接入网设备。
终端20可以散布于整个移动通信系统中,并且每个终端20可以是静止的或者移动的。终端20还可以被本领域技术人员称为移动站、用户站、移动单元、用户单元、无线单元、远程单元、移动设备、用户设备、无线设备、无线通信设备、远程设备、移动用户站、接入终端、移动终端、无线终端、远程终端、手持设备、用户代理、移动客户端、客户端或者一些其它适当的术语。终端20可以是蜂窝电话、个人数字助理(Personal Digital Assistant,PDA)、无线调制解调器、无线通信设备、手持设备、平板电脑、膝上型计算机、无绳电话、无线本地环路(Wireless Local Loop,WLL)站等。终端20能够与移动通信系统中的接入网设备10进行通信。
接入网设备10与终端20之间可通过空口技术互相通信,例如通过蜂窝技术互相通信。接入网设备10与终端20之间的通信链路可以包括:从接入网设备10到终端20的下行链路(down link,DL)传输,和/或,从终端20到接入网设备10的上行链路(up link,UP)传输。下行链路传输还可以被称为前向链路传输,上行链路传输还可以被称为反向链路传输。在一些例子中,下行链路传输可以包括发现信号的传输,该发现信号可以包括参考信号和/或同步信号。
上述图1所示的移动通信系统可以是长期演进(Long Term Evolution,LTE)系统,也可以是基于LTE系统的下一代演进系统,如LTE-A(LTE-Advanced)系统或第五代(5th Generation,5G)系统(又称NR系统),还可以是基于5G系统的下一代演进系统,等等。本申请实施例中,术语“系统”和“网络”经常被可互换地使用,但本领域技术人员可理解其含义。
本公开实施例描述的通信系统以及业务场景是为了更加清楚地说明本公开实施例的技术方案,并不构成对本公开实施例提供的技术方案的限定,本领域普通技术人员可知,随着通信系统的演变和新业务场景的出现,本公开实施例提供的技术方案对于类似的技术问题,同样适用。
为了适应不同的通信服务的需求,图1所示通信系统中存在两种终端,分别为第一终端和第二终端。两种终端的能力和/或类型不同。示例性地,终端的能力和/或类型根据终端支持的最大传输带宽来划分。下文中,将以第一终端所支持的最大传输带宽小于第二终端支持的最大传输带宽为例进行说明。
在本公开实施例中,第一终端也可以称为能力缩减新空口设备(reduced Capability NR device)、能力缩减用户设备(reduced Capability UE)或者能力受限用户设备(Capability restricted UE)。示例性地,第一终端可以为工业物联网 中的一些传感器,智慧城市中的无线视频监控设备,以及可穿戴设备如手环、手表和健康医疗监控设备等。第二设备也可以称为正常设备、普通设备,例如增强移动宽带(enhanced Mobile Broadband,eMBB)设备等。
相关技术中,随机接入过程分为基于竞争的随机接入过程和基于非竞争的随机接入过程。目前,大多数终端采用的是基于竞争的随机接入过程。基于竞争的随机接入过程包括4步随机接入过程和2步随机接入过程。下面先分别介绍这两种基于竞争的随机接入过程。
基于竞争的随机接入过程分4步完成时,每一步为一条消息(Msg,Message)。在标准中,这4步称为Msg1~Msg4。图2为基于竞争的4步随机接入过程的流程图,如图2所示,该4步随机接入过程包括:
第1步,终端向接入网设备发送Msg1。该Msg1包括随机接入前导序列(preamble)。
其中,每个小区内可用的随机接入前导序列总数为64个。在这64个随机接入前导序列中定义了两个子集,每个子集的随机接入前导序列集合作为系统信息的一部分被告知终端。当进行基于竞争的随机接入的时候,终端可以在这两个子集之中任意选取一个随机接入前导序列在物理随机接入信道(PRACH,Physical Random Access Channel)资源(即资源)上发送。
基于竞争的随机接入可用的随机接入前导序列以及用于发送随机接入前导序列的PRACH资源由接入网设备进行配置,并通过系统消息将配置结果通知到小区内的终端。
第2步,接入网设备向终端发送Msg2。该Msg2包括随机接入响应(Random Access Response,RAR)。
一条Msg2中可以包含多个由不同终端发送的Preamble序列的标识(即索引值),同时响应多个终端的随机接入请求。终端通过检测Msg2中是否携带了其所发送的Preamble序列的标识来判断是否收到了随机接入响应。
接入网设备采用物理下行控制信道(Physical Downlink Control Channel,PDCCH)调度Msg2,并通过随机接入专用无线网络临时标识(RA-RNTI,Random Access-Radio)进行寻址(也称为加扰),RA-RNTI由承载Msg1的PRACH的资源位置所确定。
该消息2中可以包括与Msg1对应的随机接入前导序列的标识、上行传输定时提前量、为终端分配的上行资源、临时C-RNTI等参数。
第3步,终端向接入网设备发送Msg3。
终端正确接收Msg2后,在Msg2中分配的上行资源中传输Msg3,完成第一次调度传输。
该Msg3中可以包括终端的身份标识信息。例如,C-RNTI标识或者临时C-RNTI标识。
第4步,接入网设备向终端发送Msg4。
接入网设备和终端通过Msg4完成最终的竞争解决。Msg4的内容和Msg3的内容相对应。
若终端未分配有C-RNTI,则接入网设备会采用临时C-RNTI加扰的PDCCH调度Msg4。终端采用临时C-RNTI在PDCCH上寻址,以得到Msg4的资源位置。寻址成功后,从该资源位置获取Msg4。Msg4通过媒体访问控制(Media Access Control Address,MAC)层控制单元(Control Element,CE)携带竞争解决标识(Contention Resolution Identity,CRI),终端在接收到该MAC CE后,与其在Msg3中发送的身份标识信息进行比较,二者相同则判定为竞争解决成功,终端确定完成随机接入。
若终端已经分配有C-RNTI,则接入网设备会采用C-RNTI加扰的PDCCH调度Msg4。终端采用C-RNTI在PDCCH上寻址,寻址成功则表示竞争解决成功,终端确定完成随机接入。
2步随机接入过程可以是由前述4步随机接入过程合并而成。图3为基于竞争的2步随机接入过程的流程图。如图3所示,该2步随机接入过程包括:
第1步,终端向接入网设备发送MsgA,接站接收MsgA。
该MsgA包括随机接入前导序列和物理上行共享信道(Physical Uplink Shared Channel,PUSCH)数据。该PUSCH数据可以包含终端的身份标识信息,例如C-RNTI等。也即是,MsgA包括Msg1和Msg3的内容。
第2步,接入网设备向终端发送MsgB,终端接收MsgB。
MsgB包括:随机接入响应和竞争解决信息。也即是,MsgB包括Msg2和Msg4的内容。其中,随机接入响应包括随机接入前导序列的标识,竞争解决信息可以包含竞争解决标识。
图4是根据一示例性实施例示出的一种用于随机接入的通信方法的流程图。 参见图4,该方法包括以下步骤:
在步骤201中,接入网设备生成配置信息,所述配置信息包括第一终端的第一随机接入参数和第二终端的第二随机接入参数,所述第一终端和所述第二终端的能力和/或类型不同,所述第一随机接入参数和所述第二随机接入参数至少部分不同;

可选地,所述第一随机接入参数包括第一上行初始接入带宽,所述第二随机接入参数包括第二上行初始接入带宽,所述第一上行初始接入带宽在频域上与所述第二上行初始接入带宽不重叠。

图6是根据一示例性实施例示出的一种用于随机接入的通信方法的流程图。该方法可以由接入网设备和终端共同执行。参见图6,该方法包括以下步骤:
在步骤401中,接入网设备生成配置信息。
该配置信息包括第一终端的第一随机接入参数和第二终端的第二随机接入参数,第一终端和第二终端的能力和/或类型不同。
在本公开实施例中,第一终端和第二终端的能力和/或类型根据终端支持的最大传输带宽划分,第一终端支持的最大传输带宽小于第二终端支持的最大传输带宽。
例如,第一终端为能力缩减设备,第二终端为eMBB设备,对于某一频带(band),第一终端支持的最大传输带宽为20M,第二终端支持的最大传输带宽为100M。
第一随机接入参数和第二随机接入参数至少部分不同。
可选地,所述第一随机接入参数包括第一上行初始接入带宽,所述第二随机接入参数包括第二上行初始接入带宽。
需要说明的是,在本公开实施例中,初始接入带宽也可以称为初始带宽部分(Initial BandWidth Part,Initial BWP)。上行是指从终端到接入网设备的传输链路;下行是指从接入网设备到终端的传输链路。对于初始接入的随机接入过程而言,需要利用该上行初始接入带宽发送消息1或者消息A,从而发起随机接入。
在一种可能的实施方式中,所述第一上行初始接入带宽在频域上与所述第二上行初始接入带宽至少部分重叠。所述第一上行初始接入带宽可以在频域上与所述第二上行初始接入带宽完全重合,占用相同的频域资源。也即是,第一终端和第二终端可以共用一个初始接入带宽。所述第一上行初始接入带宽也可 以在频域上与所述第二上行初始接入带宽的一部分重叠,例如,所述第一上行初始接入带宽的频域资源可以是所述第二行初始接入带宽的频域资源的子集。在另一个例子中,所述第一上行初始接入带宽的一部分频域资源可以与所述第二行初始接入带宽的一部分的频域资源重叠。
在另一种可能的实施方式中,所述第一上行初始接入带宽在频域上与所述第二上行初始接入带宽不重叠。也即是,第一终端和第二终端分别采用一个初始接入带宽。通过将不同能力和/或终端的初始接入带宽分开,从而使得不同能力和/或类型的终端的随机接入资源在频域上分开,从而降低了不同能力和/或类型的终端随机接入时的碰撞概率,也降低了终端随机接入时延。同时,可以降低第一终端对第二终端的影响,保证第二终端的接入性能。
示例性地,在第一终端和第二终端分别采用一个初始接入带宽的情况下,可以增加一个与现有的BWP-UplinkCommon(initialUplinkBWP)字段并列的字段,用于配置第一终端对应的第一随机接入参数。
可选地,第一随机接入参数还包括以下内容中的至少一种:用于指示第一终端是否支持2步随机接入的第一指示信息、第一随机接入资源。相关技术中,接入网设备可以通过一指示信息通知网络中的所有终端该接入网设备是否支持2步随机接入,例如,当接入网设备配置了该指示信息,则表示支持2步随机接入,如果接入网设备没有配置该指示信息,则表示不存在该指示信息。若接入网设备支持2步随机接入,则能力上支持2步随机接入的终端可以根据实际需要支持2步随机接入还是4步随机接入。本公开实施例中,通过该第一指示信息,接入网设备可以配置网络中的第一终端是否支持2步随机接入,即对网络中的某一能力和/或类型的终端进行单独指示,从而控制第一终端的随机接入过程,同时不影响第二终端。
可选地,第一指示信息指示支持2步随机接入,第一随机接入资源包括用于2步随机接入的资源和用于4步随机接入的资源;或者,第一指示信息指示不支持2步随机接入,第一随机接入资源包括用于4步随机接入的资源。
可选地,若所述第一指示信息指示第一终端支持2步随机接入,则所述第一随机接入参数还包括用于指示传输消息B的调制解调方案的第二指示信息,以保证2步随机接入过程的正常实现。
可选地,第二随机接入参数可以包括用于指示第二终端是否支持2步随机接入的第一指示信息、第二随机接入资源等内容。
可选地,第一随机接入资源和第二随机接入资源不同。
可选地,所述第一随机接入资源包括随机接入机会(RACH Occasion,RO)和/或用于传输消息A的物理上行共享信道(Physical Uplink Shared Channel,PUSCH)资源。示例性地,RO可以采用PRACH资源的索引表示,PUSCH资源可以采用时频位置表示。第一随机接入资源中的RO与第二随机接入资源中的RO不同,和/或,第一随机接入资源中的PUSCH的资源与第二随机接入资源中的PUSCH的资源也不相同,也即是,第一随机接入资源与第二随机接入资源不同,通过将不同能力和/或终端的随机接入资源在时域和/或频域上分开,从而降低了不同终端随机接入时的碰撞概率,也降低了终端随机接入时延。同时,可以降低第一终端对第二终端的影响,保证第二终端的接入性能。
可选地,该第一随机接入参数还包括用于指示RO是否支持2步随机接入的第三指示信息。针对第一终端能够使用的RO配置是否支持2步随机接入,实现更加灵活。
可选地,所述第一随机接入参数包括两组子参数,所述两组子参数对应的所述第一终端的能力和/或类型不同。
示例性地,可以根据第一终端支持的最大传输带宽进一步将第一终端分为两类,例如,第一类支持的最大传输带宽为20M,第二类支持的最大传输带宽为10M。对于两类第一终端共用的参数,可以采用一个参数表示,例如,第一上行初始接入带宽,对于两类第一终端不同的参数,可以分别表示,例如两类第一终端分别对应一个第一指示信息,第一类第一终端对应的第一指示信息指示第一终端支持2步随机接入,第二类第一终端对应的第一指示信息指示第一终端不支持2步随机接入,等等。通过将第一终端分类,可以更针对性地配置网络资源,有利于提高网络资源的利用率,同时可以细化对第一终端的控制。
在步骤402中,接入网设备发送该配置信息。
示例性地,接入网设备可以通过第一消息发送该配置信息。该第一消息可以为系统消息或者无线资源控制(Radio Resource Control,RRC)消息。
第一随机接入参数和第二随机接入参数中,相同的参数可以通过第一消息中的相同的字段指示,以便于节省需要传输的数据量。例如,若第一上行初始接入带宽和第二上行初始接入带宽在频域上重叠,则第一上行初始接入带宽和第二上行初始接入带宽采用第一消息中的同一字段指示。
在另一种可能的实施方式中,可以在现有消息的基础上增加一个字段,用 于指示该第一上行初始接入带宽。例如,可以在系统信息块(System Information Block,SIB)中增加一个与现有的BWP-UplinkCommon(initialUplinkBWP)字段并列的字段,用于携带第一随机接入参数。这里,第一随机接入参数至少包括第一上行初始接入带宽,还可以包括以下内容中的至少一种:用于指示第一终端是否支持2步随机接入的第一指示信息、第一随机接入资源。在这种情况下,该增加的字段可以包括至少一个子字段,用于承载除了初始接入带宽之外的第一随机接入参数,例如前述用于指示第一终端是否支持2步随机接入的第一指示信息、第一随机接入资源等。
需要说明的是,该增加的字段中的子字段可以与原有字段中的子字段对应的参数类型完全相同,也可以部分相同,本公开对此不作限制,只要能够携带所需要的参数即可。
第一随机接入参数和第二随机接入参数中,不同的参数可以通过第一消息中的不同的字段指示。仍然以第一消息为SIB为例,如果针对2步随机接入的相关参数不同,则可以在现有消息中增加一个与现有的rach-ConfigCommonTwoStepRA-r16字段并列的字段,用于携带第一终端的与2步随机接入相关的参数,比如第一指示信息;又例如,如果针对消息A的PUSCH资源的相关参数不同,则可以在现有消息中增加一个与现有的msgA-PUSCH-Config-r16字段并列的字段,用于指示第一随机接入资源中的PUSCH资源。
在步骤403中,终端接收该配置信息。
在该步骤403中,终端接收通过该第一消息发送的配置信息。
在步骤404中,终端基于终端的能力和/或类型,根据第一随机接入参数和第二随机接入参数确定目标随机接入参数。
可选地,该步骤404可以包括:
若该终端的能力和/或类型表示该终端为第一终端,则将第一随机接入参数确定为目标随机接入参数;或者,
若该终端的能力和/或类型表示该终端为第二终端,则将第二随机接入参数确定为目标随机接入参数。
可选地,若终端需要发起初始随机接入,则该方法还可以包括步骤405和步骤406。
在步骤405中,终端确定随机接入方式。
示例性地,该步骤405可以包括:
终端确定所述终端与接入网设备之间的路径损耗值;
所述终端基于所述路径损耗值与路损阈值的大小关系,确定随机接入方式。
例如,若路径损耗值大于路损阈值,则确定随机接入方式为4步随机接入方式;或者,若路径损耗值小于路损阈值,则确定随机接入方式为2步随机接入方式。
在本公开实施例中,第一终端和第二终端对应的路损阈值的大小不同。
在步骤406中,终端根据确定出的随机接入方式,向接入网设备发送消息A或者消息1。
步骤406可以包括:
响应于确定出随机接入方式为2步随机接入,所述终端采用所述用于2步随机接入的资源发送消息A;或者,
响应于确定出随机接入方式为4步随机接入,所述终端采用所述用于4步随机接入的资源发送消息1。
需要说明的是,终端采用2步随机接入的资源发送消息A之后的过程可以参见图3相关内容,终端采用用于4步随机接入的资源发送消息1之后的过程可以参见图2相关内容,在此省略详细描述。
本公开实施例通过为不同能力和/或类型的终端配置不同的随机接入参数,从而使得不同的终端能够采用各自适合的随机接入参数进行随机接入,从而保证终端的随机接入性能。
