目前,在初始接入阶段,网络设备给终端设备配置一个初始下行带宽部分(bandwidth part,BWP)和一个初始上行BWP,在终端设备进入无线资源控制(radio resource control,RRC)连接态之后,网络设备给终端设备额外配置一个或者多个用户专属上行BWP和一个或者多个用户专属下行BWP。
5G中引入RedCap终端设备之后,在现有的初始下行BWP和初始上行BWP基础上,还提出为RedCap终端设备额外配置单独的初始下行BWP和初始上行BWP,也就是说,对于RedCap终端设备,可以配置两个初始下行BWP和两个初始上行BWP。
在为RedCap终端设备配置多个初始下行BWP和初始上行BWP,以及多个用户专属上行BWP、多个用户专属下行BWP的情况下,如何与网络侧进行高效的通信,还没有一个明确的解决方案。

6、支持的载波聚合(carrier aggregation,CA)能力不同,例如,第二类型终端设备可以支持载波聚合,而第一类型终端设备不支持载波聚合;又例如,第二类型终端设备与第一类型终端设备都支持载波聚合,但是第二类型终端设备支持的载波聚合的最大个数大于第一类型终端设备支持的载波聚合的最大个数,例如第二类型终端设备可以最多支持5个 载波或者32个载波的聚合,而第一类型终端设备最多同时支持2个载波的聚合。
7、通信模式不同,例如第二类型终端设备支持全双工频分双工(frequency division duplex,FDD),而第一类型终端设备仅支持半双工FDD。
8、处理能力不同,第一类型终端设备的处理能力小于第二类型终端设备的处理能力。
第二类型终端设备与第一类型终端设备具有但不限于上述区别特征。
一种可能的实现方式中,第一类型终端设备可以是指降低能力(reduced capability,REDCAP)终端设备,或者,第一类型终端设备还可以是指低能力终端设备、降低能力终端设备、REDCAP UE、Reduced Capacity UE、窄带NR(narrow-band NR,NB-NR)UE等。第二类型终端设备可以是指传统能力或正常能力或高能力的终端设备,也可以称为传统(legacy)终端设备或者常规(normal)终端设备。
在本申请实施例中,网络设备可以为各种制式下无线接入设备,可以是5G移动通信系统中的下一代基站(next generation NodeB,gNB)、基站(base station)、演进型基站(evolved NodeB,eNodeB)、发送接收点(transmission reception point,TRP)、开放无线接入网(open radio access network,O-RAN)中的接入网设备、第六代(6th generation,6G)移动通信系统中的下一代基站、未来移动通信系统中的基站或无线保真(wireless fidelity,WiFi)系统中的接入节点等;或者可以是完成基站部分功能的模块或单元,例如,可以是集中式单元(central unit,CU)、分布式单元(distributed unit,DU)、集中单元控制面(CU control plane,CU-CP)模块、或集中单元用户面(CU user plane,CU-UP)模块。
本申请实施例中,涉及到带宽部分(bandwidth part,BWP)。BWP是频域上一段连续的资源,按照传输方向可以分为上行BWP和下行BWP,分别用于上行传输和下行传输。本申请以BWP为例进行说明,更为一般地,BWP可以称为频域资源等,不限于BWP这个名称,当BWP用其他术语描述时,该术语对应的频率资源与BWP具有相同的特征,即由连续的资源块(resource block,RB)组成,频率范围不大于第一类型终端设备支持的信道带宽能力,以及数据传输时只在被激活的频率资源内进行。
在初始接入阶段,网络侧可以给终端设备配置初始上行BWP和初始下行BWP,在终端设备进入RRC连接态之后,网络侧可以给终端设备额外配置一个或者多个用户专属的上行BWP和一个或者多个用户专属的下行BWP。用户专属BWP也可以称之为RRC配置的BWP(RRC-configured BWP),为了描述方便,以下统称为用户专属BWP。
对于第一类型终端设备和第二类型终端设备,在初始接入阶段,网络设备会配置初始下行BWP,网络设备可以在初始下行BWP上配置系统信息块1(system information block1,SIB1)搜索空间(search space,SS)、寻呼消息(paging)SS、其他系统信息(other system information,OSI)SS、随机接入(random access,RA)SS,分别用于在初始下行BWP上监听SIB1、paging、OSI、随机接入响应(random access response,RAR)消息等信息。
初始下行BWP有如下几种配置方式,在接收SIB1之前以及接收SIB1时,初始下行BWP的位置和带宽由控制资源集合0(control resource set 0,CORESET0)确定,具体可以由CORESET0的频域资源定义,CORESET0的配置信息包含于主信息块(master information block,MIB)中,终端设备获取到MIB就可以确定CORESET0,从而可以确定初始下行BWP。
在接收SIB1之后,网络设备还可以在SIB1中重配置该初始下行BWP的位置和带宽,但重配置的初始下行BWP的位置和带宽必须在终端设备进入RRC连接态之后才能生效, 在此之前,初始下行BWP的位置和带宽仍由CORESET0的频域资源定义。如果网络设备没有在SIB1中重配置该初始下行BWP的位置和带宽,则该初始下行BWP的位置和带宽一直由CORESET0的频域资源定义。
对于第一类型终端设备和第二类型终端设备,在初始接入阶段,网络设备还会配置初始上行BWP,终端设备可以通过初始上行BWP进行随机接入的上行传输,例如传输随机接入过程中的消息1(message 1,Msg1)、消息3(message 3,Msg3)、消息4的混合自动重传请求(hybrid automatic repeat request,HARQ)反馈(feedback)物理上行控制信道(physical uplink control channel,PUCCH)(即PUCCH for Msg4 HARQ feedback)等,其中Msg1通过物理随机接入信道(physical random access channel,PRACH)发送,网络设备在初始上行BWP上配置PRACH时机(PRACH occasion,RO)资源用于发送PRACH。
其中,随机接入过程可以依次包含4步消息流程:终端设备发送消息1,该消息1可以是指随机接入前导码;网络设备发送消息2,消息2可以是指随机接入响应(random access response,RAR)消息;终端设备发送消息3,消息3可以是指消息2的响应消息;网络设备发送消息4,消息4可以是指竞争解决消息。
其中,如果终端设备采用时分双工(time division duplex,TDD)频段,上行BWP和下行BWP是成对出现的,并且具有相同的BWP标识(identifier,ID),且具有相同BWP ID的上行BWP和下行BWP具有相同的中心频点,当上行BWP或者下行BWP切换时,其关联的下行BWP或者上行BWP同时发生切换。如果终端设备采用FDD频段,没有上述限制。
前面描述了在初始接入阶段,对于第一类型终端设备和第二类型终端设备,网络设备会配置初始上行BWP。在此之外,网络设备还可以为第一类型终端设备额外配置单独的初始下行BWP和初始上行BWP,也就是说对于第一类型终端设备,可能会为其配置两个初始上行BWP以及两个初始下行BWP。
本申请实施例中,将网络设备为第一类型终端设备额外配置单独的初始下行BWP称为第一初始下行BWP,将为第一类型终端设备额外配置单独的初始上行BWP称为第一初始上行BWP。将在初始接入阶段,网络设备通过CORESET0配置或通过SIB1重配置的初始下行BWP称为第二初始下行BWP,所述第二初始下行BWP可以理解是指为第二类型终端设备配置的,当所述第二初始下行BWP的带宽不大于第一类型终端设备支持的最大带宽时,第一类型设备也可以使用所述第二初始下行BWP;将在初始接入阶段,网络设备通过SIB1配置的初始上行BWP称为第二初始上行BWP,所述第二初始上行BWP可以理解是指为的第二类型终端设备配置的,当所述第二初始上行BWP的带宽不大于第一类型终端设备支持的最大带宽时,第一类型设备也可以使用所述第二初始上行BWP。
其中,第二初始下行BWP配置paging SS、RA SS、SIB1 SS、OSI SS,第二初始上行BWP上配置RO资源。第一初始下行BWP可以支持配置paging SS、RA SS、SIB1 SS、OSI SS,也可以支持不配置paging SS、RA SS、SIB1 SS、OSI SS中的至少一项;也就是说,对于上述任一SS,网络设备可以在第一初始下行BWP中配置该SS,也可以不配置该SS。相应的,第一初始上行BWP可以支持配置RO资源,也可以支持不配置RO资源,即网络设备可以在第一初始上行BWP中配置RO资源,也可以不配置RO资源。如果所述第一初始上行BWP中配置有RO资源,终端设备可以通过所述RO资源发送PRACH,即发起随机接入。
本申请实施例中,在网络侧为第一类型终端设备配置的第一初始下行BWP上,没有配置paging SS、RA SS、SIB1 SS以及OSI SS中的至少一项时,终端设备可以通过切换到第二初始下行BWP实现监听paging、RAR消息、SIB1、OSI;在网络侧为第一类型终端设备配置的第一初始上行BWP上,没有配置RO资源时,终端设备可以通过切换到第二初始下行BWP实现发起随机接入,下面将详细描述。
在本申请的各个实施例中,如果没有特殊说明以及逻辑冲突,不同的实施例之间的术语和/或描述具有一致性、且可以相互引用,不同的实施例中的技术特征根据其内在的逻辑关系可以组合形成新的实施例。
可以理解的是,在本申请中涉及的各种数字编号仅为描述方便进行的区分,并不用来限制本申请的范围。上述各过程的序号的大小并不意味着执行顺序的先后,各过程的执行顺序应以其功能和内在逻辑确定。
本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案,并不构成对于本申请实施例提供的技术方案的限定,本领域普通技术人员可知,随着网络架构的演变和新业务场景的出现,本申请实施例提供的技术方案对于类似的技术问题,同样适用。
本申请实施例中,以网络设备与终端设备之间交互为例进行说明,网络设备执行的操作也可以由网络设备内部的芯片或模块执行,终端设备执行的操作也可以由终端设备内部的芯片或模块执行。其中,终端设备可以为第一类型终端设备。
在本申请实施例中,虽然以第一类型终端设备为例进行描述,但所列举的实施方式也同样适用于其他类型的终端设备,例如NR Rel-17或及以后的终端设备。为便于描述,本申请以第一类型终端设备为例进行描述,本申请提供的方法适用于其他类型终端设备的情况不再赘述。
本申请实施例中,可以按照终端设备进入初始接入阶段和进入初始接入之后的阶段(即终端设备处于RRC连接态)分别进行描述,下面先描述终端设备在初始接入阶段如何接收消息和发送消息。
如图2所示,为本申请实施例提供的一种消息传输方法流程示意图。在图2所示的流程之前,网络设备可以为终端设备配置第一初始上行BWP和第一初始下行BWP,以及配置第二初始上行BWP和第二初始下行BWP,具体配置过程不做限定。
可选地,S201:网络设备确定发送第一消息,相应的,终端设备确定接收第一消息。
其中,第一消息可以包括以下至少一项:
寻呼消息;随机接入响应消息;系统信息块1;其他系统信息。
举例来说,第一消息为用于指示对系统信息进行更新的寻呼消息,网络设备确定更新系统信息时,可以确定发送第一消息;相应的,终端设备接收第一消息,根据第一消息确定系统信息是否更新。
再举例来说,第一消息为随机接入响应消息,网络设备接收到来自终端设备的随机接入前导码时,确定发送第一消息;相应的,终端设备发送随机接入前导码之后,可以确定接收第一消息。
再举例来说,第一消息为系统信息块1,系统信息块1为周期性广播的消息,系统信息块1可以指示其他系统信息的调度信息,也可以指示小区的配置参数。当系统信息块1的广播周期到达时,网络设备可以确定发送第一消息;相应的,终端设备需要接收系统信 息块1以获得相应的小区配置参数时,接收第一消息。
再举例来说,第一消息为其他系统信息,其他系统信息可以为周期性广播的消息,其他系统信息也可以指示小区的配置参数。当其他系统信息的广播周期到达时,网络设备可以确定发送第一消息;相应的,终端设备需要接收其他系统信息以获得相应的小区配置参数时,接收第一消息。
以上只是示例,第一消息还可能为其他类型的消息,在此不再逐一举例说明。
S202:若第一初始下行带宽部分上未配置第一消息对应的搜索空间,网络设备在第二初始下行带宽部分上的搜索空间中调度第一消息,终端设备在第二初始下行带宽部分上使用该搜索空间监听第一消息。
第一消息对应的搜索空间,可以是指用于调度第一消息的搜索空间。
一种具体实施方式,若第一初始下行带宽部分上未配置第一消息对应的搜索空间,终端设备从第一初始下行带宽部分切换到第二初始下行带宽部分,终端设备在第二初始下行带宽部分上使用该搜索空间监听第一消息。具体地,终端设备在要接收第一消息或者说要监听第一消息时,如果激活带宽部分为第一初始下行带宽部分,则触发带宽部分切换或者射频(radio frequency,RF)重调,切换到第二初始下行带宽部分,在第二初始下行带宽部分上使用该搜索空间监听第一消息。
若第一初始下行带宽部分上配置第一消息对应的搜索空间,网络设备可以在第一初始下行带宽部分上的搜索空间中调度第一消息,终端设备在第一初始下行带宽部分上使用该搜索空间监听第一消息。
其中,第二初始下行带宽部分为根据CORESET0确定的下行带宽部分,该CORESET0为终端设备在初始接入阶段通过MIB确定的;或者,第二初始下行带宽部分为通过SIB1配置的,该第二初始下行带宽部分,是对根据CORESET0确定的下行带宽部分的位置和带宽重配置后的下行带宽部分。
第二初始下行带宽部分还可以关联第二初始上行带宽部分,第二初始下行带宽部分和第二初始上行带宽部分可以具有相同的带宽部分标识以及具有相同的中心频点。第二初始上行带宽部分的配置方式可以与第二初始下行带宽部分的配置方式相同,在此不再赘述。
当终端设备从第一初始下行带宽部分切换到第二初始下行带宽部分时,终端设备还会从第一初始上行带宽部分切换到第二初始上行带宽部分,反之亦然。相应的,网络设备在第二初始下行带宽部分上的搜索空间中调度第一消息时,网络设备将在第二初始上行带宽部分中接收终端设备的上行消息,反之亦然。
第一初始下行带宽部分是为第一类型终端设备单独配置的初始下行带宽部分,即第一类型终端设备专属的初始下行带宽部分。第一初始下行带宽部分还可以关联第一初始上行带宽部分,第一初始下行带宽部分和第一初始上行带宽部分可以具有相同的带宽部分标识以及具有相同的中心频点。
第一初始下行带宽部分和第一初始上行带宽部分具体如何配置,本申请实施例对此并不限定。第一种实现方式中,网络设备可以配置第一初始下行带宽部分和第一初始上行带宽部分中的至少一项。具体的,网络设备可以通过SIB1或者RRC信令配置第一初始下行带宽部分和第一初始上行带宽部分中的至少一项。当通过SIB1或者RRC信令配置第一初始下行带宽部分时,可以配置第一初始下行带宽部分的带宽和频域位置,以及其所承载的物理信道或者物理信号等信息,例如可以在第一初始下行带宽部分中配置paging SS、RA SS、 SIB1 SS以及OSI SS中的至少一项。
当通过SIB1或者RRC信令配置第一初始上行带宽部分时,可以配置第一初始上行带宽部分的带宽和频域位置,以及其所承载的资源等信息,例如可以在第一初始上行带宽部分中配置RO资源等。
第二种实现方式中,网络设备可以配置第一初始下行带宽部分,网络设备可以通过SIB1或者RRC信令配置第一初始下行带宽部分,第一初始上行带宽部分由第一初始下行带宽部分确定,例如,第一初始上行带宽部分的带宽和频域位置可以由第一初始下行带宽部分的带宽和频域位置确定。
第三种实现方式中,网络设备可以配置第一初始上行带宽部分,网络设备可以通过SIB1或者RRC信令配置第一初始上行带宽部分,第一初始下行带宽部分由第一初始上行带宽部分确定,例如,第一初始下行带宽部分的带宽和频域位置可以由第一初始上行带宽部分的带宽和频域位置确定。
上面的流程中,以网络设备与终端设备之间传输下行消息为例进行描述,当网络设备与终端设备之间传输上行消息(例如第二消息)时,可以采用相同的方法,具体的:
若第一初始上行带宽部分上未配置第二消息对应的资源,终端设备在第二初始上行带宽部分上使用所述资源发送第二消息,相应的,网络设备在第二初始上行带宽部分上通过所述资源接收第二消息。其中第二消息为上行消息,例如第二消息可以为随机接入消息1,随机接入消息1也可以是指随机接入前导码。第二消息对应的资源,可以是指用于传输第二消息的资源。
一种具体实施方式,若第一初始上行带宽部分上未配置第二消息对应的资源,终端设备从第一初始上行带宽部分切换到第二初始上行带宽部分,终端设备在第二初始上行带宽部分上使用第二消息对应的资源发送第二消息。具体地,终端设备在发送第一消息时,如果激活带宽部分为第一初始上行带宽部分,则触发BWP切换或者RF重调,切换到第二初始上行带宽部分,在第二初始上行带宽部分上使用第二消息对应的资源发送第二消息。
另外,若第一初始上行带宽部分上配置第二消息对应的资源,终端设备可以在第一初始上行带宽部分上使用所述资源发送第二消息,相应的,网络设备在第一初始上行带宽部分上通过所述资源接收第二消息。
通过实施上面的方法,第一初始下行带宽部分上没有配置第一消息对应的搜索空间时,网络设备可以在配置了该搜索空间的第二初始下行带宽部分上调度第一消息,终端设备可以在第二初始下行带宽部分上接收第一消息,可以保证终端设备能够及时监听第一消息,避免终端设备无法监听第一消息的情况发生。
同样的,第一初始上行带宽部分上没有配置第二消息对应的资源时,终端设备可以在第二初始上行带宽部分上发送第二消息,网络设备可以在第二初始上行带宽部分上接收第二消息,避免终端设备无法发送第二消息。
下面通过具体的实施例描述前面的流程。
假设网络设备在为终端设备配置的第一初始下行带宽部分上可选地配置SIB1 SS、OSI SS、paging SS、RAR SS中的一个或者多个SS,在第一初始上行带宽部分上可选地配置RO资源;网络设备在为终端设备配置的第二初始下行带宽部分上配置有SIB1 SS、OSI SS、paging SS、RAR SS,在第二初始上行带宽部分上配置有RO资源。
其中,RAR SS和RO资源可以是成对配置的,即如果在第一初始下行带宽部分上配 置RAR SS,那么也会在第一初始上行带宽部分上配置RO资源,如果在第一初始下行带宽部分上没有配置RAR SS,那么也不会在第一初始上行带宽部分上配置RO资源,反之亦然。
一种实现方式中,终端设备以及网络设备优先使用配置有SIB1 SS、OSI SS、paging SS、RAR SS中的一个或者多个SS的初始下行带宽部分;终端设备以及网络设备优先使用配置有RO资源的初始上行带宽部分。
例如,如果第一初始下行带宽部分上没有配置SIB1 SS、OSI SS、paging SS、RAR SS,则终端设备以及网络设备优先使用第二初始下行带宽部分。再例如,如果第一初始上行带宽部分上没有配置RO资源,则终端设备以及网络设备优先使用第二初始上行带宽部分。
一种实现方式中,网络设备通过信令指示终端设备使用的初始下行带宽。
一种实现方式中,终端设备通过预定义规则确定使用的初始下行带宽。
一种实现方式中,如果第一初始下行带宽部分上配置了SIB1 SS、OSI SS、paging SS、RAR SS中的一个或者多个SS,对于配置的SS,网络设备可以在第一初始下行带宽部分上所配置的SS中调度相应的消息,终端设备可以在第一初始下行带宽部分上使用所配置的SS监听相应的消息。
如果第一初始下行带宽部分上没有配置SIB1 SS、OSI SS、paging SS、RAR SS中的一个或者多个SS,对于没有配置的SS,网络设备不在第一初始下行带宽部分上调度该SS对应的消息,终端设备不在第一初始下行带宽部分上监听该SS对应的消息。进一步地,网络设备在第二初始下行带宽部分上调度该SS对应的消息,终端设备在第二初始下行带宽部分上使用该SS监听该SS对应的消息。
举例来说,对于SIB1 SS,如果第一初始下行带宽部分上配置了SIB1 SS,网络设备可以在第一初始下行带宽部分的SIB1 SS中调度SIB1;终端设备可以在第一初始下行带宽部分上使用SIB1 SS监听SIB1。当然,网络设备也可以在第二初始下行带宽部分的SIB1 SS中调度SIB1,终端设备也可以在第二初始下行带宽部分上使用SIB1 SS监听SIB1,具体根据实际情况确定。
如果第一初始下行带宽部分上没有配置SIB1 SS,网络设备可以在第二初始下行带宽部分的SIB1 SS中调度SIB1;终端设备可以切换到第二初始下行带宽部分,可以在第二初始下行带宽部分上使用SIB1 SS监听SIB1。
对于OSI SS和paging SS,也可以采用同样的方法,在此不再赘述。
对于RAR和随机接入前导码中的至少一项,其传输过程可以如下:
假设第一初始下行带宽部分和第一初始上行带宽部分为激活带宽部分,如果第一初始下行带宽部分上配置了RAR SS,且第一上行带宽部分上配置了RO资源,那么终端设备可以在第二上行带宽部分上通过所述RO资源发送PRACH,网络设备可以在第二上行带宽部分上通过所述RO资源接收PRACH。其中,PRACH中承载随机接入前导码,随机接入前导码用于发起随机接入过程。
如果第一初始下行带宽部分上没有配置RAR SS,和/或,第一上行带宽部分上没有配置RO资源,终端设备可以从第一初始下行带宽部分切换到第二初始下行带宽部分,从第一初始上行带宽部分切换到第二初始上行带宽部分。
可选地,终端设备可以在第二初始上行带宽部分上通过所述RO资源发送PRACH,网络设备在第二初始上行带宽部分上通过所述RO资源接收PRACH。
可选地,网络设备在第二初始下行带宽部分上的RAR SS中调度RAR,终端设备在第二初始下行带宽部分上使用RAR SS监听RAR。
本申请还适用于终端设备进入初始接入之后的阶段,在图3所示的流程之前,网络设备除了为终端设备配置第一初始上行BWP、第一初始下行BWP、第二初始上行BWP和第二初始下行BWP之外,还可以配置第一下行带宽部分以及第一上行带宽部分,具体配置过程不做限定。第一下行带宽部分以及第一上行带宽部分可以为用户专属带宽部分。
如图3所示,为本申请实施例提供的一种消息传输方法流程示意图。
可选地,S301:网络设备确定发送第一消息,相应的,终端设备确定接收第一消息。
其中,第一消息可以包括以下至少一项:
寻呼消息;随机接入响应消息;系统信息块1;其他系统信息。
S302:若第一下行带宽部分上未配置第一消息对应的搜索空间,在第二下行带宽部分上配置所述搜索空间时,网络设备在第二下行带宽部分上的搜索空间中调度第一消息,终端设备在第二下行带宽部分上使用所述搜索空间监听第一消息。
一种实现方式中,若所述第一下行带宽部分为激活带宽部分,终端设备从第一下行带宽部分切换到第二下行带宽部分,终端设备还可以从第一上行带宽部分切换到第二上行带宽部分;相应的,网络设备在第二下行带宽部分上的搜索空间中调度第一消息时,网络设备还将在第二上行带宽部分中调度终端设备的上行消息,反之亦然。
可选地,S303:在第二下行带宽部分上没有配置所述搜索空间时,网络设备在第三下行带宽部分上的所述搜索空间中调度第一消息,终端设备在第三下行带宽部分上使用所述搜索空间监听第一消息。
一种实现方式中,若所述第一下行带宽部分为激活带宽部分,终端设备从第一下行带宽部分切换到第三下行带宽部分时,终端设备还可以从第一上行带宽部分切换到第三上行带宽部分;相应的,网络设备在第三下行带宽部分上的搜索空间中调度第一消息时,网络设备还将在第三上行带宽部分中调度终端设备的上行消息,反之亦然。
上面的流程中,以网络设备与终端设备之间传输下行消息为例进行描述,当网络设备与终端设备之间传输上行消息(例如第二消息)时,可以采用相同的方法,具体的:
若第一上行带宽部分上未配置第二消息对应的资源,在第二上行带宽部分上配置所述资源时,终端设备在第二上行带宽部分上通过所述资源发送第二消息,网络设备在第二上行带宽部分上通过所述资源接收第二消息。第二消息可以为PRACH或者随机接入前导码,第二消息对应的资源可以为RO资源。其中,若第一上行带宽部分为激活带宽部分,在发送第二消息之前,终端设备可以从第一上行带宽部分切换到第二上行带宽部分。
可选地,若在第二上行带宽部分上没有配置第二消息对应的资源,终端设备在第三上行带宽部分上通过所述资源发送第二消息,网络设备在第三上行带宽部分上通过所述资源接收第二消息。其中,若第一上行带宽部分为激活带宽部分,在发送第二消息之前,终端设备可以从第一上行带宽部分切换到第三上行带宽部分。
需要说明的是,若第一下行带宽部分上配置第一消息对应的搜索空间,那么网络设备也可以在第一下行带宽部分上的搜索空间中调度第一消息,终端设备也可以在第一下行带宽部分上使用所述搜索空间监听第一消息。若第一上行带宽部分上配置第二消息对应的资源,那么终端设备也可以在第一上行带宽部分上通过所述资源发送第二消息,网络设备也 可以在第一上行带宽部分上通过所述资源接收第二消息。
其中,第一下行带宽部分和第一上行带宽部分关联。第一下行带宽部分上可选地配置第一消息对应的搜索空间,即第一下行带宽部分上可以支持配置第一消息对应的搜索空间,也可以支持不配置第一消息对应的搜索空间。
本申请实施例中,第三下行带宽部分上配置了第一消息对应的搜索空间,第三上行带宽部分上配置了第二消息对应的资源。第三下行带宽部分可以指网络设备为终端设备配置的第二初始下行带宽部分。例如第三下行带宽部分为根据控制资源集合0确定的下行带宽部分;或者,第三下行带宽部分为通过系统信息块1配置的。第三下行带宽部分可以关联第三上行带宽部分,第三上行带宽部分可以为网络设备为终端设备配置的第二初始上行带宽部分。第三下行带宽部分和第三上行带宽部分可以具有相同的带宽部分标识以及具有相同的中心频点。第三上行带宽部分的配置方式可以与第三下行带宽部分的配置方式相同,在此不再赘述。第二初始下行带宽部分和第二初始上行带宽部分的具体含义,可以参考前面的描述,在此不再赘述。
本申请实施例中,第二下行带宽部分也可以关联第二上行带宽部分,第二下行带宽部分和第二上行带宽部分可以具有相同的带宽部分标识以及具有相同的中心频点。第一种实现方式中,第二下行带宽部分为网络设备为终端设备配置的第一初始下行带宽部分,第二上行带宽部分为网络设备为终端设备配置的第一初始上行带宽部分。第一初始下行带宽部分和第一初始上行带宽部分的具体含义,可以参考前面的描述,在此不再赘述。
该实现方式中,第二下行带宽部分可选地配置第一消息对应的搜索空间,即第二下行带宽部分可以支持不配置所述搜索空间,也可以支持配置所述搜索空间。
第二上行带宽部分可选地配置第二消息对应的资源,即第二上行带宽部分可以支持不配置第二消息对应的资源,也可以支持配置第二消息对应的资源。
第二种实现方式中,第二下行带宽部分为网络设备为终端设备配置的第二初始下行带宽部分,第二上行带宽部分为网络设备为终端设备配置的第二初始上行带宽部分。
该实现方式中,第二下行带宽部分配置了第一消息对应的搜索空间,第二上行带宽部分上配置了第二消息对应的资源。
第三种实现方式中,第二下行带宽部分与第一初始下行带宽部分和第二初始下行均不同,第二下行带宽部分可以是网络设备通过SIB1或者用户专属RRC信令配置的,或者是可以通过其他方法预定义或者预配置确定的。同样的,第二上行带宽部分可以是网络设备通过SIB1或者用户专属RRC信令配置的,或者是可以通过其他方法预定义或者预配置确定的。
该实现方式中,第二下行带宽部分可选地配置第一消息对应的搜索空间,第二上行带宽部分可选地配置第二消息对应的资源。
该实现方式中,第二下行带宽部分和第二上行带宽部分可以是网络设备为处于RRC连接态的终端设备配置的,即终端设备处于RRC连接态时,第二下行带宽部分和第二上行带宽部分才生效。
结合前面的描述,下面通过一个具体的实施例描述前面的过程。
假设网络设备在为终端设备配置的第一下行带宽部分上可选地配置paging SS和RAR SS中的一个或者多个SS,在第一上行带宽部分上可选地配置RO资源。
网络设备在为终端设备配置的第一初始下行带宽部分上可选地配置SIB1 SS、OSI SS、 paging SS、RAR SS中的一个或者多个SS,在第一初始上行带宽部分上可选地配置RO资源。
网络设备在为终端设备配置的第二初始下行带宽部分上配置有SIB1 SS、OSI SS、paging SS、RAR SS,在第二初始上行带宽部分上配置有RO资源。
其中,RAR SS和RO资源可以是成对配置的。
一种实现方式中,对于RAR和随机接入前导码中的至少一项,其传输过程可以如下:
假设第一下行带宽部分和第一上行带宽部分为激活带宽部分,如果第一下行带宽部分上没有配置RAR SS,和/或,第一上行带宽部分上没有配置RO资源,那么如果第二下行带宽部分上配置有RAR SS,并且第二上行带宽部分上配置有RO资源,则执行以下操作:

可选地,终端设备可以在第二上行带宽部分上通过所述RO资源发送PRACH,网络设备可以在第二上行带宽部分上通过所述RO资源接收PRACH;
