下面结合附图介绍本公开的实施例。本公开实施例提供的模式指示方法、终端设备及网络设备可以应用于无线通信系统中。该无线通信系统可以为采用第五代(5th Generation,5G)移动通信技术的系统(以下均简称为5G系统),所述领域技术人员可以了解,5G NR系统仅为示例,不为限制。
参见图1,图1是本公开实施例可应用的一种网络系统的结构图,如图1所示,包括用户终端11和基站12,其中,用户终端11可以是用户设备(User Equipment,UE),例如:可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant,简称PDA)、移动上网装置(Mobile Internet Device,MID)或可穿戴式设备(Wearable Device)等终端侧设备,需要说明的是,在本公开实施例中并不限定用户终端11的具体类型。上述基站12可以是5G及以后版本的基站(例如:gNB、5G NR NB),或者其他通信系统中的基站,或者称之为节点B,需要说明的是,在本公开实施例中仅以5G基站为例,但是并不限定基站12的具体类型。
在进行本公开实施例说明前,先对下文中所提到的一些概念进行解释说明。
新空口(New Radio,NR)系统正在考虑在高于52.6GHz频段的物理层信道、信号、程序和协议的设计。在高频段的潜在应用例包括增强移动带宽(Enhanced Mobile Broadband,eMBB),移动数据卸载,短距离高数据速率设备间通信(Device-to-Device,D2D)通信,宽带配电网络,集成接入回程,工厂自动化,工业物联网(Industry Internet of things,IIOT),无线显示传输,增强现实(Augmented Reality,AR)/虚拟现实(Virtual Reality,VR)可穿戴设备,智能传输系统(Intelligent Transportation Systems,ITS),车联网(Vehicle-to-Everything,V2X),数据中心机架连接,智能电网自动化,专用网络以及高定位精度支持等。第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)已经确定在当地法规允许No-LBT操作的非授权频段支持两种信道接入模式,LBT模式与No-LBT模式。
在新空口非授权频段(New Radio Unlicensed,NR-U)中,NR系统的物理层控制信令设计如下。当系统工作在非授权频段时,被小区无线网络临时 标识(Cell Radio Network Temporary Identifier,C-RNTI)或配置调度无线网络临时标识(Configured Scheduling Radio Network Temporary Identifier,CS-RNTI)或调制编码策略小区无线网络临时标识(Modulcation Coding Scheme Cell Radio Network Temporary Identifier,MCS-C-RNTI)或临时小区无线网络临时标识(Temporary Cell Radio Network Temporary Identifier,TC-RNTI)加扰的下行控制信息(Downlink Control Information,DCI)format 0_0和被C-RNTI或CS-RNTI或MCS-C-RNTI或TC-RNTI加扰的DCI format 1_0中的ChannelAccess-CPext域承载2bit的信息,用于指示用户设备(User Equipment,UE,也称终端)信道接入类型与循环前缀(Cyclic Prefix,CP)扩展的组合;否则,此域为0bit。
当系统工作在非授权频段且存在高层参数配置的情况下,DCI format 0_1和DCI format 1_1中的ChannelAccess-CPext-CAPC(具体地,CAPC表示信道接入优先级)域承载0,1,2,3,4,5或6比特(bit)的信息,用于指示UE的信道接入方式;否则,此域为0bit。
对于系统信息无线网络临时标识(System Information,SI-RNTI)加扰的DCI,当系统工作在非授权频段上时,被SI-RNTI加扰的DCI format 1_0有17bit的保留位;否则是15bit的保留位。对于P-RNTI加扰的DCI,被P-RNTI加扰的DCI format 1_0有8bit的保留位;否则是6bit的保留位。对于物理广播信道(Physical Broadcast Channel,PBCH)的预留域(spare域)存在1bit位置用于指示备用的主信息块(Master Information Block,MIB)信息。
本公开实施例提供了一种模式指示方法、终端设备及网络设备,用以解决终端不知道其当前所处的信道接入模式,影响后续操作的问题。
其中,方法和设备是基于同一申请构思的,由于方法和设备解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。
如图2所示,本公开实施例提供一种模式指示方法,由终端设备执行,包括:
步骤S201,接收网络设备发送的第一指示信息;
需要说明的是,所述第一指示信息用于指示终端设备在第一非授权频段的信道接入模式;具体地,所述信道接入模式包括:先听后说(LBT)模式 或非先听后说(No-LBT)模式。
需要说明的是,该第一非授权频段为高频的非授权频段,即大于52.6GHz的非授权频段,也就是说,本公开实施例适用的是非授权频段中的高频段。
需要说明的是,终端设备通过接收网络设备发送的用于指示终端设备在高频的非授权频段的信道接入模式,在终端设备处于LBT模式时,终端设备在接收到下行控制信息(DCI)时需要解码与非授权频段信道接入相关信息域内的信息,例如,终端设备需要解码ChannelAccess-CPext和ChannelAccess-CPext-CAPC信息域中的内容;在终端设备处于No-LBT模式时,则终端设备在接收到DCI时无需解码非授权频段信道接入相关信息域内的信息,例如,终端设备无需解码ChannelAccess-CPext和ChannelAccess-CPext-CAPC信息域中的内容。
进一步需要说明的是,该信道接入模式可以是针对小区的(即Cell-specific),此时,网络设备配置小区内的终端设备全部处于LBT模式或No-LBT模式;也可以是针对终端设备的(即UE-specific),此时,网络设备配置小区内的终端设备部分处于No-LBT模式,另一部分处于LBT模式。
具体地,当信道接入模式为Cell-specific时,本公开实施例的步骤S201的具体实现方式为:
接收网络设备通过第一信令发送的第一指示信息;
其中,所述第一信令,包括以下至少一项:
A11、系统消息的调度信令;
需要说明的是,此种情况下,网络设备通过调度信令中预留位(也可以称为保留位)的M bit携带第一指示信息,其中,M为大于或等于1的整数。
例如,该系统消息的调度信令为系统信息无线网络临时标识(SI-RNTI)加扰的DCI,也就是说在SI-RNTI加扰的DCI的预留位中新增一个模式指示域,例如,该模式指示域占用1bit,用于指示终端设备在非授权频段是处于LBT模式还是处于No-LBT模式。例如,当模式指示域中为0时,表示LBT模式,为1时,表示No-LBT模式;或者,当模式指示域中为1时,表示LBT模式,为0时,表示No-LBT模式。
可选地,在所述信道接入模式为No-LBT模式的情况下,DCI中与信道 接入类型相关的域为0比特,也就是说,在所述信道接入模式为No-LBT模式的情况下,DCI中不携带LBT相关的信息,以此降低终端设备解码DCI的复杂度。
A12、主信息块;
需要说明的是,此种情况下,网络设备通过主信息块中的预留域中的1比特携带所述第一指示信息。例如,该主信息块为在物理广播信道(PBCH),此时,网络设备通过PBCH中的预留域(Spare域)内的1bit发送第一指示信息,当该比特为0时,表示LBT模式,为1时,表示No-LBT模式;或者,当该比特为1时,表示LBT模式,为0时,表示No-LBT模式。
A13、系统消息;
需要说明的是,此种情况下,网络设备通过系统消息中的N比特携带所述第一指示信息,其中,N为大于或等于1的整数。
例如,该系统消息可以为系统信息块一(SIB 1),该系统消息也可以为除SIB 1外的其他SIB;也就是说在SIB 1或其他SIB中新增一个模式指示域(可以看作是LBT模式指示域),例如,该模式指示域占用1bit,用于指示终端设备在非授权频段是处于LBT模式还是处于No-LBT模式。例如,当模式指示域中为0时,表示LBT模式,为1时,表示No-LBT模式;或者,当模式指示域中为1时,表示LBT模式,为0时,表示No-LBT模式。
或者,系统信息块中的LBT模式指示域是一个可选的配置域。当在系统信息块一(SIB 1)中存在LBT模式指示域时指示终端在非授权频段是处于LBT模式;当在系统信息块一(SIB 1)中不存在LBT模式指示域时,隐式的指示终端在非授权频段是处于No-LBT模式,换句话说即终端未处于LBT模式;
或者,当在系统信息块(SIB 1)中增加LBT模式指示域且为多比特(例如,2bit)时,其中一种状态指示终端在非授权频段是处于LBT模式,且发送竞争豁免短控制信令也不需要执行LBT;其中一种状态指示终端在非授权频段是处于LBT模式,且发送竞争豁免短控制信令需要执行LBT;其中一种状态指示终端在非授权频段是处于No-LBT模式。
或者,系统信息块中的LBT模式指示域是一个可选的配置域。当在系统 信息块(SIB 1)中存在LBT模式指示域且为多比特(例如,2bit)时,其中一种状态指示终端在非授权频段是处于LBT模式,且发送竞争豁免短控制信令也不需要执行LBT;其中一种状态指示终端在非授权频段是处于LBT模式,且发送竞争豁免短控制信令需要执行LBT;当在系统信息块一(SIB 1)中不存在LBT模式指示域时,隐式的指示终端在非授权频段是处于No-LBT模式,换句话说即终端未处于LBT模式;
注意,竞争豁免短控制信令至少包括SSB,发现信号,Msg 1/Msg A。其中发现信号至少包括与同步信号/广播信道(SS/PBCH)相关联的用于调度SIB1的PDCCH的控制资源集(CORESET),用于调度SIB1的PDSCH和非零功率CSI-RS。
或者,当在系统信息块(SIB 1)中增加LBT模式指示域且为多比特(例如,3bit)时,其中一种状态指示终端在非授权频段是处于LBT模式,且发送SSB,发现信号和Msg1/Msg A不需要执行LBT;其中一种状态指示终端在非授权频段是处于LBT模式,且发送SSB,发现信号不需要执行LBT,发送Msg1/Msg A需要执行LBT;其中一种状态指示终端在非授权频段是处于LBT模式,且发送SSB,发现信号需要执行LBT,发送Msg1/Msg A不需要执行LBT;其中一种状态指示终端在非授权频段是处于LBT模式,且发送SSB,发现信号和Msg1/Msg A需要执行LBT;其中一种状态指示终端在非授权频段是处于No-LBT模式;
或者,系统信息块中的LBT模式指示域是一个可选的配置域。当在系统信息块(SIB 1)中存在LBT模式指示域且为多比特(例如,2bit)时,其中一种状态指示终端在非授权频段是处于LBT模式,且发送SSB,发现信号和Msg1/Msg A不需要执行LBT;其中一种状态指示终端在非授权频段是处于LBT模式,且发送SSB,发现信号不需要执行LBT,发送Msg1/Msg A需要执行LBT;其中一种状态指示终端在非授权频段是处于LBT模式,且发送SSB,发现信号需要执行LBT,发送Msg1/Msg A不需要执行LBT;其中一种状态指示终端在非授权频段是处于LBT模式,且发送SSB,发现信号和Msg1/Msg A需要执行LBT;当在系统信息块一(SIB 1)中不存在LBT模式指示域时,隐式的指示终端在非授权频段是处于No-LBT模式,换句话说即 终端未处于LBT模式。
A14、寻呼调度信令;
需要说明的是,此种情况下,网络设备通过寻呼调度信令中预留位的K比特携带所述第一指示信息,其中,K为大于或等于1的整数。
例如,该寻呼调度信令为寻呼无线网络临时标识(P-RNTI)加扰的DCI,也就是说在P-RNTI加扰的DCI的预留位中新增一个模式指示域,例如,该模式指示域占用1bit,用于指示终端设备在非授权频段是处于LBT模式还是处于No-LBT模式。例如,当模式指示域中为0时,表示LBT模式,为1时,表示No-LBT模式;或者,当模式指示域中为1时,表示LBT模式,为0时,表示No-LBT模式。
需要说明的是,上述的A11-A14中,A11和A12可以认为是在RRC连接之前获取网络设备的第一指示信息,当终端设备与网络设备进行RRC连接后,若终端设备的模式发生变更,则网络设备通过A14进行模式的变更指示。
可选地,在所述信道接入模式为No-LBT模式的情况下,DCI中与信道接入类型相关的域为0比特,也就是说,当网络设备指示终端设备处于No-LBT模式时,网络设备发送的DCI中可以不携带LBT相关的信息,以此降低终端设备解码DCI的复杂度。
具体地,当信道接入模式针对UE-specific时,本公开实施例的步骤S201的具体实现方式为:
接收网络设备通过无线资源控制(RRC)信令发送的第一指示信息。
此种情况下,网络设备通过RRC信令为特定终端设备指示处于LBT模式还是No-LBT模式,例如,网络设备可以在RRC信令中的带宽部分上行专用域(BWP-UplinkDedicated域)或带宽部分下行专用域(BWP-DownDedicated域)中携带该第一指示信息,网络设备也可以在RRC信令的其他域中携带该第一指示信息。
具体地,当在BWP-UplinkDedicated域中增加1bit用于携带第一指示信息时,网络设备所指示的LBT模式或No-LBT模式是针对于上行带宽部分的,也就是说,终端设备只有在上行带宽部分处于网络设备所指示的LBT模式或No-LBT模式,当在BWP-DownDedicated域中增加1bit用于携带第一指示信 息时,网络设备所指示的LBT模式或No-LBT模式是针对于下行带宽部分的,也就是说,终端设备只有在下行带宽部分处于网络设备所指示的LBT模式或No-LBT模式,具体地,当第一指示信息的比特位为0时,表示LBT模式,为1时,表示No-LBT模式;或者,当第一指示信息的比特位为1时,表示LBT模式,为0时,表示No-LBT模式。例如,终端在建立RRC连接后接收到UE-specific的模式指示的信令配置时,若接收到IE BWP-UplinkDedicated域或IE BWP-DownDedicated域内第一指示信息为0,则此时终端在对应的BWP内处于LBT模式;若接收到IE BWP-UplinkDedicated域或IE BWP-DownDedicated域内第一指示信息为1,则此时终端在对应的BWP内处于No-LBT模式。
或者,通过BWP-UplinkDedicated中PUCCH-Config域中UL-AccessConfigListForDCI-Format1-1-r16和/或PUSCH-Config域中UL-AccessConfigListForDCI-Format0-1-r16的隐式地指示信道接入模式信息。若为终端配置了UL-AccessConfigListForDCI-Format1-1-r16和/或UL-AccessConfigListForDCI-Format0-1-r16,终端处于LBT模式;否则处于No-LBT模式。
这里需要特别说明的是,当网络设备通知终端设备处于No-LBT模式时,非授权频段中的RRC信令ul-AccessConfigListForDCI-Format1-1与IE ul-AccessConfigListForDCI-Format0-1的配置方式与授权频段的配置方式一致。
如果第一指示信息指示为LBT模式,则DCI中ChannelAcess-CPext域的比特长度由BWP-UplinkDedicated中PUCCH-Config域中UL-AccessConfigListForDCI-Format1-1-r16和/或PUSCH-Config域中UL-AccessConfigListForDCI-Format0-1-r16的确定;否则为0bit。
可选地,在获取到针对小区的信道接入模式指示和针对终端设备的信道接入模式指示的情况下,根据针对终端设备的信道接入模式指示所对应的第一指示信息进行所述终端设备所处的信道接入模式的确定;
需要说明的是,针对小区的信道接入模式指示即小区级别的信道接入指示,终端设备在接收到网络设备通过系统消息的调度信令、主信息块、系统 消息和寻呼调度信令发送的第一指示信息的情况下,可以隐式确定获取到针对小区的信道接入模式指示;针对终端的信道接入模式指示即终端级别的信道接入指示,终端设备在接收到网络设备通过无线资源控制RRC信令发送的第一指示信息的情况下,可以隐式确定获取到针对终端设备的信道接入模式指示。
也就是说,当终端设备先获取到网络设备发送的Cell-specific的信道接入模式后,又获取到网络设备发送的UE-specific的信道接入模式,终端设备将UE-specific的信道接入模式作为最高优先级来确定其处于的信道接入模式;例如,终端设备先获取到网络设备发送的Cell-specific的信道接入模式为No-LBT模式,在此No-LBT模式下,终端设备不解码DCI中与非授权频段信道接入相关信息域内的信息,之后终端设备又接收到网络设备发送的UE-specific的信道接入模式为LBT模式,则终端设备确定处于LBT模式,终端设备需要解码DCI中与非授权频段信道接入相关信息域内的信息。
可选地,在所述信道接入模式为No-LBT模式的情况下,DCI中与信道接入类型相关的域为0比特,也就是说,当网络设备指示终端设备处于No-LBT模式时,网络设备发送的DCI中可以不携带LBT相关的信息,以此降低终端设备解码DCI的复杂度。
综上可知,本公开实施例通过接收网络设备发送的指示终端设备在高频的非授权频段的信道接入模式的第一指示信息,明确了终端设备所处于的信道接入模式,方便了终端设备的后续操作;同时,本公开实施例的实现方式,使得终端设备无需一直解码DCI中与信道接入相关域内的信息,此种方式,节省了终端设备功耗。

场景一、终端通过系统消息的调度信令(SI-RNTI加扰的DCI format 1_0)保留位进行cell-specific配置,获得第一指示信息所指示的LBT/No-LBT模式。例如,基站利用系统消息的调度信令中保留位中的1个bit或多个bit指示LBT/No-LBT模式,涉及过程如图4所示,具体为:
终端接收SI-RNTI加扰的DCI format 1_0;
当终端接收并解码SI-RNTI加扰的DCI format 1_0中保留位中的第一指示信息后,若终端被指示处于No-LBT模式,则终端在解码被C-RNTI\CS-RNTI\MCS-C-RNTI\TC-RNTI加扰的DCI format 0_0或被C-RNTI\CS-RNTI\MCS-C-RNTI\随机接入无线网络临时标识(Random Access Radio Network Temporary Identifier,RA-RNTI)\MsgB-RNTI\TC-RNTI加扰的DCI format 1_0时无需解码ChannelAccess-CPext域;若终端被指示处于No-LBT模式,则终端在解码被C-RNTI\CS-RNTI\半持续信道状态信息无线网络临时标识(Semi-Persistent Channel State Information Radio Network Temporary Identifier,SP-CSI-RNTI)\MCS-C-RNTI加扰的DCI format 0_1或被C-RNTI\CS-RNTI\MCS-C-RNTI加扰的DCI format 1_1时无需解码ChannelAccess-CPext-CAPC域;

当终端所处的LBT/No-LBT模式发生变更时,终端只需要解码被P-RNTI加扰的DCI中保留位的第一指示信息所占用的比特位,即可知道当前所处的LBT/No-LBT模式,其指示方式包括如下:
第一种候选方案:当被P-RNTI加扰的DCI中的第一指示信息所占用的比特位为0时,终端处于LBT模式;当第一指示信息所占用的比特位为1时,终端处于No-LBT模式;反之亦然。
第二种候选方案:当P-RNTII加扰的DCI中的第一指示信息所占用的比特位为0时,终端的LBT/No-LBT模式保持不变;当第一指示信息所占用的比特位为1时,终端的LBT/No-LBT模式翻转,即由LBT模式变为No-LBT模式,由No-LBT模式变为LBT模式。
