还应理解,图1所示的通信***100还可以是NTN***,也就是说,图1中的网络设备110可以是卫星。
应理解,本文中术语“***”和“网络”在本文中常被可互换使用。
为了方便对本申请实施例的理解,下面先对三个概念进行介绍。
1、5G NR***
当前,随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性、复杂性,为此第三代移动通信标准化组织(3rd Generation Partnership Project,3GPP)国际标准组织开始研发5G。5G的主要应用场景为:增强移动宽带(Enhanced Mobile Broadband,eMBB)、超可靠低时延通信(Ultra Reliability and Low Latency Communication,URLLC)、大规模机器类通信(Massive Machine Type Communications,mMTC)。
NR也可以独立部署,5G网络环境中基于降低空口信令和快速恢复无线连接,快速恢复数据业务的目的,定义了一个新的无线资源控制(Radio Resource Control,RRC)状态:RRC非激活(RRC_INACTIVE)态。RRC_INACTIVE态有别于RRC空闲(RRC_IDLE)态和RRC激活(RRC_ACTIVE)态。
其中,对于RRC_IDLE态来说,移动性为基于终端设备的小区选择重选,寻呼由核心网发起,寻呼区域由核心网配置。网络设备侧不存在终端设备接入层(Access Stratum,AS)上下文。RRC_IDLE态也不存在RRC连接。
对于RRC_CONNECTED态来说,存在RRC连接,网络设备和终端设备存在终端设备AS上下文,终端设备和网络设备之间可以传输单播数据。网络侧知道终端设备的位置是具体小区级别的。移动性是网络侧控制的移动性。
对于RRC_INACTIVE态来说,移动性为基于终端设备的小区选择重选,存在核心网-NR之间的连接,终端设备AS上下文存在某个网络设备上,寻呼由无线接入网(Radio Access Network,RAN)触发,基于RAN的寻呼区域由RAN管理,网络侧知道终端设备的位置是基于RAN的寻呼区域级别的。
2、NR-light终端设备
在R17中,NR引入了NR-light终端设备的概念。目前,NR-light终端设备主要有三个应用场景:
(a)工业无线传感器。和URLLC相比,工业无线传感器具有相对低要求的时延和可靠性。此外,与URLLC场景和eMBB场景的成本和功耗相比,NR-light终端设备的成本和功耗较低。
(b)视频监控。NR-light终端设备主要可以用于智慧城市、工业工厂等视讯监控中,以及还可以用于智能城市中数据的收集和处理,以便于更有效的进行城市资源的监测和控制,为城市居民提供更有效的服务。
(c)可穿戴设备。其中,可穿戴设备可以包括智能手表、戒指、电子健康设备以及一些医疗监测设备等。这些设备的尺寸较小。
上述三种场景存在共性需求,具体可以为:
(a)设备成本。和R15或R16中的eMBB场景相比,上述三种场景要求更低的设备成本和复杂度。其中,可以通过降低带宽和接收天线来降低NR-light终端设备的成本和复杂度。
(b)设备尺寸。上述三种场景都要求比较小的设备尺寸。
(c)覆盖率。上述三种场景要求达到与R15或R16中的eMBB相同的覆盖率。如果由于降低接收天线、降低带宽、降低功率等级或者其他降低终端设备复杂度等带来的覆盖损失则需要补偿。
针对上述三种场景,除了前述内容提到的共性需求外,不同的场景还有不同的需求。
对于工业无线传感器来说,可靠性的需求为99.99%,端到端的时延需求为100ms,比特(Bit)速率的需求为2Mbps。该场景要求NR-light终端设备静止不动,电池寿命为几年。对于安全相关的传感器,时延需求为5-10ms。
对于视频监控来说,Bit速率的需求为2-4Mbps,时延需求小于500ms,可靠性需求为99%-99.9%。
对于可穿戴设备来说,Bit速率的需求为150Mbps或50Mbps。
3、带宽部分(BandWidth Part,BWP)
NR***中支持的最大信道带宽可以到400MHZ,如果终端设备一直保持工作在宽带载波上,则终端设备的功率消耗是很大的。根据终端设备实际的吞吐量来调整终端设备的射频带宽可以优化终端设备的功率消耗。因此,5G NR中引入了BWP的概念,即终端设备可以在整个大带宽的载波内的一部分连续的带宽(即BWP)上进行数据收发。
对于处于RRC_CONNECTED态的终端设备来说,网络设备最多可以给终端设备配置4个(Downlink,DL)BWP以及最多配置4个(Uplink,UL)BWP。一个时刻最多只能有一个激活的下行DLBWP和一个激活的上行ULBWP。
对于频分双工(Frequency Division Duplex,FDD)***,UL BWP和DL BWP之间没有对应(association)关系。比如,网络设备可以为一个连接态终端设备配置4个UL BWP和4个DL BWP,其中,4个UL BWP的索引(index)分别为0、1、2和3,4个DL BWP的index分别为0、1、2和3。当前激活的UL BWP index可以是0,当前激活的DL BWP index可以是1。如果网络设备通过下行控制信息(Downlink Control Information,DCI)指示终端设备将DL BWP切换到另外一个DL BWP,比如从当前激活的DL BWP 1切换到DL BWP 2,UL BWP可以保持不变。
处于RRC_IDLE态和RRC_INACTIVE态的终端设备可以通过小区定义同步信号块 (Cell Defining-Synchronization Signal Block,CD-SSB)获取驻留小区的主信息块(Master Information Block,MIB)和***信息块1(System Information Block 1,SIB1)信息。SIB1可以指示用于终端设备初始接入的初始BWP(initial BWP)相关配置信息,其中初始BWP可以包括初始上行BWP(initial UL BWP)和初始下行BWP(initial DL BWP)。在initial UL BWP配置中,网络设备可以为初始接入的终端设备配置随机接入资源(RACH-ConfigCommon),随机接入资源和SSB之间存在对应关系。网络设备可以通过配置一个参考信号接收功率(Reference Signal Receiving Power,RSRP)门限(rsrp-ThresholdSSB)控制终端设备随机接入资源的选择。当随机接入过程被触发时,终端设备可以选择一个RSRP测量值满足RSRP门限的SSB,然后根据随机接入资源和SSB的对应关系确定选择的SSB对应的随机接入资源,之后,终端设备可以利用选择的随机接入资源发送随机接入前导码(preamble),即消息1(Msg1),并在选择的SSB上监听网络设备发送的随机接入响应消息(即Msg2)。
目前,所有处于RRC_IDLE态和RRC_INACTIVE态的终端设备可以通过SIB1中指示的正常上行(Normal UL,NUL)载波或者辅助上行(Supplementary UL,SUL)载波上的initial UL BWP来接入网络,这对于负荷较轻的eMBB等场景是可以的。未来网络部署中会引入NR-light终端设备,由于NR-light终端设备的数量很多,这些海量终端设备的引入可能会对小区上行容量造成冲击,比如可能会对初始接入资源以及连接状态下使用的上行传输资源造成冲击。
鉴于此,本申请实施例提出了一种随机接入的方法,可以增加终端设备进行随机接入的上行容量,从而有效提高终端设备接入网络的成功率。
图2是根据本申请实施例的随机接入的方法200的示意性图。图2所述的方法可以由终端设备执行,该终端设备例如可以为图1中所示的终端设备120。如图2所示,该方法200可以包括以下内容中的至少部分内容。
在210中,终端设备在多个配置的随机接入资源配置中,确定目标随机接入资源配置。其中,该目标随机接入资源配置用于终端设备进行随机接入,该多个随机接入资源配置可以属于一个initial UL BWP,或者,该多个随机接入资源配置可以位于不同的UL BWP中。
本申请实施例,终端设备可以获取到属于一个initial UL BWP或位于不同的UL BWP的多个配置的随机接入资源配置,从而可以提高终端设备在initial UL BWP上的接入容量。这样,当有多个终端设备同时进行随机接入时,可以减小多个终端设备同时选择同一个随机接入资源配置的概率,从而可以有效提高终端设备接入网络的成功率。
可选地,当多个随机接入资源资源配置位于不同的UL BWP中时,该不同的UL BWP可以包括多个initial UL BWP。具体而言,不同的UL BWP中的每个UL BWP可以包括一个initial UL BWP,每个UL BWP中除initial UL BWP之外的其他BWP为专属BWP。在该情况中,每个initial UL BWP可以包括至少一个随机接入资源配置。
可选地,多个随机接入资源配置中每个随机接入资源配置对应的随机接入资源的至少一个参数可以不同。示例性地,参数可以为但不限于频域位置、时域位置、周期以及数量等。
可选地,该终端设备可以为NR-light终端设备。
可选地,该终端设备可以处于RRC空闲态,或者,可以处于RRC非激活态,当然,该终端设备也可以处于RRC连接态。
在一种可能的实施例中,网络设备可以向终端设备发送配置信息,该配置信息用于指示多个随机接入资源配置,或者,该配置信息可以用于指示目标随机接入资源配置。
实施例1
配置信息可以承载于服务小区的***消息中,例如,配置信息可以承载于SIB1中。
在该实施例中,一种可能的方式可以为SIB1指示一个initial UL BWP,该initial UL  BWP中包括多个随机接入资源配置。具体的信令路径如下:
SIB1→ServingCellConfigCommonSIB→UplinkConfigCommonSIB→BWP-UplinkCom mon→List Of RACH-ConfigCommon。
从上述信令路径中可以看到,网络设备可以在BWP-UplinkCommon中配置一个随机接入信道(Random Access Channel,RACH)-ConfigCommon资源配置列表,从而终端设备可以在该RACH-ConfigCommon资源配置列表中确定目标随机接入资源配置。
网络设备配置一个initial UL BWP,该initial UL BWP中包括多个随机接入资源配置的代码实现可以为:
Figure PCTCN2019119778-appb-000001
TAG-BWP-UPLINKCOMMON-STOP
ASN1STOP
另一种可能的方式可以为SIB1指示多个initial UL BWP,该多个initial UL BWP中的每个initial UL BWP可以包括至少一个随机接入资源配置。具体的信令路径如下:
Figure PCTCN2019119778-appb-000002
TAG-UPLINKCONFIGCOMMONSIB-STOP
ASN1STOP
下面以SIB1指示了一个initial UL BWP为例,介绍终端设备在多个随机接入资源配置中确定目标随机接入资源配置的实现方式。
方式一
终端设备可以在多个随机接入资源配置中,随机选择目标随机接入资源配置。
在方式一的技术方案中,终端设备随机选择目标随机接入资源配置,可以降低大量终端设备选择到同一个随机接入资源配置上的概率。
方式二
终端设备可以基于每个随机接入资源配置对应的选择因子,在多个随机接入资源配置中选择目标随机接入资源。
其中,选择因子表示终端设备选择每个随机接入资源配置的概率。例如,SIB1指示了2个随机接入资源配置,分别为随机接入资源配置1和随机接入资源配置2,随机接入资源配置1对应的选择因子为0.3,随机接入资源配置2对应的选择因子为0.7,则终端设备在发起随机接入时,选择选择随机接入资源配置1的概率为0.3,选择随机接入资源配置2的概率为0.7。
可选地,终端设备可以将最大的选择因子对应的随机接入资源配置确定为目标随机接入资源配置。例如,SIB1指示了2个随机接入资源配置,分别为随机接入资源配置1和随机接入资源配置2,随机接入资源配置1对应的选择因子为0.3,随机接入资源配置2对应的选择因子为0.7。由于随机接入资源配置1对应的选择因子小于随机接入资源配置2对应的选择因子,因此,终端设备在发起随机接入时,可以将随机接入资源配置2确定为目标随机接入资源配置,并利用随机接入资源配置2进行随机接入。
可选地,每个随机接入资源配置对应的选择因子可以都相同,即不同的随机接入资源配置对应一个选择因子。例如,SIB1指示了4个随机接入资源配置,每个随机接入资源配置的选择因子均为0.25,也就是说终端设备在发起随机接入时,选择这四个随机接入资源配置中的任何一个随机接入资源配置的概率相同。
可选地,该多个随机接入资源配置中的第一随机接入资源配置对应的选择因子可以为a,多个随机接入资源配置中除第一随机接入资源配置之外的其他随机接入资源配置对应的选择因子b可以满足:
b=(1-a)/n
其中,n为多个随机接入资源配置中除第一随机接入资源配置之外的其他随机接入资源配置的数量。
第一随机接入资源配置可以用于所有的终端设备进行随机接入,其他随机接入资源配置只能用于部分终端设备进行随机接入。示例性地,该部分终端设备可以为NR-light终端设备。
可选地,服务小区可以额外广播该多个随机接入资源配置中的每个随机接入资源配置对应的选择因子。即SIB1中可以包括该多个随机接入资源配置中的每个随机接入资源配置对应的选择因子。
可选地,网络设备可以单独配置每个随机接入资源配置对应的选择因子,即每个随机接入资源配置对应的选择因子彼此之间是不关联的。例如,四个随机接入资源配置对应的选择因子分别为{a,b,c,d},均由网络设备通过显示信令配置。
应理解,本申请实施例对选择因子的名称并不限定,也就是说,选择因子还可以表述为其他名称,如权重因子、随机数因子等。
方式三
终端设备可以基于随机接入资源配置与终端设备的业务类型之间的对应关系,以及进行的上行业务,在多个随机接入资源配置中选择目标随机接入资源;和/或
终端设备可以根据随机接入资源配置与终端设备类型之间的对应关系,以及终端设备的类型,在多个随机接入资源配置中选择目标随机接入资源。
示例性地,微信业务对应随机接入资源配置1,语音业务对应随机接入资源配置2,若终端设备当前进行的上行业务为微信业务,则终端设备可以将随机接入资源配置1确定为目标随机接入资源配置。
再示例性地,工业无线传感器终端设备对应随机接入资源配置1,视频监控终端设备对应随机接入资源配置2,可穿戴终端设备对应随机接入资源配置3。若终端设备的类型为可穿戴终端设备,则终端设备可以将随机接入资源配置3确定为目标随机接入资源配 置。
可选地,服务小区可以额外广播随机接入资源配置与终端设备的业务类型之间的对应关系,和/或,随机接入资源配置与终端设备类型之间的对应关系。即SIB1中可以包括随机接入资源配置与终端设备的业务类型之间的对应关系,和/或,随机接入资源配置与终端设备类型之间的对应关系。
应理解,本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。
方式三的技术方案,终端设备根据终端设备的类型和/或业务类型类确定适合终端设备和/或业务的随机接入资源配置,比如不同的随机接入资源配置可以有不同观点周期、不同的资源数量等,从而可以达到匹配各类终端设备流量和负载均衡的目的和效果。
应理解,方式二和方式三的实施方式既可以单独实施,也可以结合实施例,本申请实施例对此并不限定。
还应理解,当SIB1指示了多个initial UL BWP时,终端设备确定目标随机接入资源配置的实现方式可以参考方式一至方式三的相关描述。例如,终端设备可以在多个initial UL BWP中,随机选择一个initial UL BWP,并将该initial UL BWP中包括的随机接入资源配置确定为目标随机接入资源配置。以下为了简洁,不再赘述。
实施例2,配置信息可以承载于RRC连接释放消息中。
当终端设备处于RRC连接态时,网络设备可以调度终端设备在任意一个终端设备专属的BWP上进行数据传输。当网络设备决定释放终端设备到RRC空闲态或RRC非激活态时,网络设备可以在RRC连接释放消息中指示终端设备下次触发随机接入过程时可以使用的随机接入资源配置,即RRC连接释放消息可以用于指示多个随机接入资源配置。
作为一种示例,RRC连接释放消息可以指示一个initial UL BWP,该initial UL BWP中可以包括多个随机接入资源配置。
作为另一种示例,RRC连接释放消息可以指示多个initial UL BWP,该多个initial UL BWP中的每个initial UL BWP可以包括至少一个随机接入资源配置。
进一步地,RRC连接释放消息还可以用于指示该多个随机接入资源配置中的每个随机接入资源配置的有效时间。
可选地,有效时间可以为绝对时间。比如该多个随机接入资源配置中的每个随机接入资源配置的有效时间可以为每天的10点到14点。若终端设备在中午12点触发随机接入,则该多个随机接入资源配置是有效的,终端设备可以在该多个随机接入资源配置中选择目标随机接入资源配置。
可选地,有效时间可以为终端设备接收到RRC连接释放消息后的预设时长。比如,预设时长为10个时隙,则终端设备接收到RRC连接释放消息后的10个时隙内该多个随机接入资源配置是有效的。再比如,该多个随机接入资源配置中的前一部分随机接入资源配置的有效时间为终端设备接收到RRC连接释放消息后的10分钟,该多个随机接入资源配置中的后一部分随机接入资源配置的有效时间为终端设备接收到RRC连接释放消息后的20分钟,若终端设备接收到RRC连接释放消息后的第15分钟触发了随机接入,则该多个随机接入资源配置中的后一部分随机接入资源配置是有效的,终端设备可以在该多个随机接入资源配置中的后一部分随机接入资源配置中选择目标随机接入资源配置。
RRC连接释放消息在指示多个随机接入资源配置的有效时间时,可以将多个随机接入资源配置作为一个整体进行指示,即RRC连接释放消息可以只指示一个有效时间。如此,可以节省信令的开销。此时,多个随机接入资源配置的有效时间是相同的。
或者,RRC连接释放消息可以指示每个随机接入资源配置的有效时间。在该情况下,多个随机接入资源配置的有效时间可以相同,也可以不同。
若RRC连接释放消息未指示该多个随机接入资源配置中的每个随机接入资源配置的有效时间,则终端设备可以默认在进入RRC连接态之前,该多个随机接入资源配置一直有效。
当终端设备触发随机接入时,终端设备可以在该多个随机接入资源配置中确定目标随接入资源配置。终端设备在该多个随机接入资源配置中确定目标随接入资源配置的实现方式可以参考前述实施例的描述,此处不再进行过多描述。
或者,RRC连接释放消息可以用于指示目标随机接入资源配置。可选地,RRC连接释放消息可以显示指示目标随机接入资源配置,
可选地,RRC连接释放消息也可以隐式指示目标随机接入资源配置。比如,RRC连接释放消息可以指示目标随机接入资源配置的索引。再比如,RRC连接释放消息可以指示目标随机接入资源配置在该多个随机接入资源配置中的编号。再比如,RRC连接释放消息可以指示SSB,当终端设备接收到SSB后,终端设备可以根据随机接入资源配置和SSB之间的对应关系以及根据RRC连接释放消息指示的SSB,确定目标随机接入资源配置。
其中,随机接入资源配置和SSB之间的对应关系可以是预设的。或者,随机接入资源配置和SSB之间的对应关系还可以是根据信令确定的。示例性地,网络设备可以向终端设备发送映射信息,终端设备接收到映射信息后,可以根据该映射信息确定随机接入资源配置和SSB之间的对应关系。
当RRC连接释放消息用于指示目标随机接入资源配置时,进一步地,RRC连接释放消息还可以用于指示目标随机接入资源配置的有效时间。
在终端设备进RRC空闲态或RRC非激活态后,终端设备可以利用目标随机接入资源配置进行随机接入。
作为一种示例,在终端设备进RRC空闲态或RRC非激活态后,终端设备可以在任何情况下利用目标随机接入资源配置进行随机接入。
作为另一种示例,若第一小区和第二小区相同,终端设备可以利用目标随机接入资源配置进行随机接入。其中,第一小区为终端设备进入RRC空闲态或RRC非激活态后所在的小区,第二小区为终端设备接收RRC连接释放消息时所在的小区。也就是说,终端设备只有在同一个小区下可以使用目标随机接入资源配置进行随机接入。
上述技术方案,网络设备知道处于RRC连接态的终端设备的业务类型和信号指廊,同时网络设备可以获取到每个随机接入资源配置上的负载情况,针对相对静止的终端设备,网络设备通过专用信令的控制,可以将终端设备定向到负荷较轻的随机接入资源配置上,从而可以提高随机接入的成功率。
在另一种可能的实施例中,网络设备可以向终端设备发送DCI,该DCI用于指示目标随机接入资源配置。
可选地,在本申请实施例中,若终端设备在非initial UL BWP上触发随机接入,且该非initial UL BWP上没有随机接入资源,则终端设备可以切换到initial UL BWP上进行随机接入,并在配置了多个随机接入资源配置的initial UL BWP中,选择目标随机接入资源配置。其中,该initial UL BWP可以为包括该多个随机接入资源配置的initial UL BWP,或者,该initial UL BWP也可以为不同的UL BWP中包括的initial UL BWP。
需要说明的是,终端设备在配置了多个随机接入资源配置的initial UL BWP中,选择目标随机接入资源配置的实现方式上文已有详细描述,为了内容的简洁,此处不再赘述。
上文结合图2从终端设备的角度描述了本申请实施例的随机接入的方法,下面将结合图3从网络设备的角度描述本申请实施例的随机接入的方法。
图3是根据本申请实施例的随机接入的方法300的示意性图。图3所述的方法可以由网络设备执行,该网络设备例如可以为图1中所示的网络设备110。如图3所示,该方 法300可以包括以下内容中的至少部分内容。
