具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
下面先对本申请中涉及到的一些术语做一个简要的说明,如下所示:
一、5G NR
5G新无线通信系统(New radio,NR)的研究目前主要考虑两个频段,频段FR1(Frequency range1)和频段FR2(Frequency range 2),其中,FR1和FR2包括的频域范围如表1所示。应理解,本申请实施例可以应用于FR1和FR2频段,也可以应用于其他频段,例如52.6GHz到71GHz的频段,或71GHz到100GHz的频段等,本申请对此并不限定。
表1
频段定义 对应频段范围
FR1 410MHz–7.125GHz
FR2 24.25GHz–52.6GHz
当前5G的主要应用场景为:增强移动超宽带(enhanced mobile broadband,eMBB)、低时延高可靠通信(ultra-reliable and low latency communications,URLLC)、大规模机器类通信(massive machine type communication,mMTC)。
相关技术中,新空口(new radio,NR)可以独立部署,5G网络环境中为了降低空口信令、快速恢复无线连接,以及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,即RRC_非激活(inactive)态。这种状态有别于RRC_空闲(idle)态和RRC_连接(connected)态。下面分别对5G网络环境中的三种RRC状态进行说明。
RRC_idle:移动性为基于终端设备的小区重选,寻呼由核心网发起,寻呼区域由核心网配置,基站侧不存在用户设备(user equipment,UE)接入层(access layer,AS)上下文,不存在RRC连接。
RRC_connected:存在RRC连接,基站和UE存在UE AS上下文,网络侧知道UE的位置是具体小区级别的,移动性是网络侧控制的移动性,UE和基站之间可以传输单播数据。
RRC_inactive:移动性为基于UE的小区选择重选,存在CN-NR之间的连接,UE AS上下文存在某个基站上,寻呼由(无线接入网)RAN触发,基于RAN的寻呼区域由RAN管理,网络侧知道UE的位置是基于RAN的寻呼区域级别的。
二、低能力(reduced capability,RedCap)终端应用场景
在R15/R16NR中所支持的eMBB、URLLC等应用场景之外,工业无线传感器、视频监控和可穿戴设备等终端物联网用例,对5G终端提出了降低复杂度、降低成本、尺寸间校、降低能耗等新的需求。为此,在R17NR中引入了RedCap终端,目前RedCap终端主要有三个场景:
(1)工业无线传感器(Industrial Wireless Sensors),工业无线传感器和URLLC相比,具有相对低要求的时延和可靠性。同时这个设备的成本和功耗也比URLLC和eMBB要低。该终端类型的主要需求和特征包括:通信可靠性99.99%,端到端时延<100ms,参考数据速率小于2Mbps,以上行业务为主,设备静止,要求电池使用时间长达几年。其中,对于用于安全相关的传感器,时延要求更低,为5~10ms。
(2)视频监控(Video surveillance),主要用在智慧城市,工业工厂等视讯监控。智能城市中数据收集和处理,以便于更有效的进行城市资源的监测和控制,给城市居民提供更有效的服务。其中,视频监控以上行业务为主,其他主要需求还包括:普通分辨率视频的参考速率为2~4Mbps,时延低于500ms,通信可靠性99%~99.9%。高清视频的速率需求为7.5~25Mbps
(3)可穿戴设备(Wearables),包括智能手表,智能手环,电子健康设备以及一些医疗监测设备等。这些设备的一个共性就是小尺寸的设备。这类终端设备的关键指标要求包括:下行、上行参考速率分别为5~50Mbps和2~5Mbps;下行峰值速率为150Mbps、上行峰值速率为50Mbps。要求电池能工作数天甚至1~2周。
三、降低终端复杂度与成本的方案
面向eMBB应用,为了提供更高的峰值速率、频率效率和网络容量,3GPP标准对eMBB UE提出了较高的要求。例如,针对NR FR1频段,eMBB UE需要支持100MHz载波带宽、4个接收链路(即4Rx)、4流多输入多输出(Multiple Input Multiple Output,MIMO)传输,256正交调幅(Quadrature Amplitude Modulation,QAM)调制和1Gbps以上的峰值速率等功能和性能指标,对终端的射频器件和基带芯片处理能力提出了较高要求,决定了eMBB UE较高的复杂度和成本。
针对RedCap UE,在R17RedCap SI阶段,主要研究了从以下几个方面来降低终端能力要求,从而实现复杂度和成本的降低。
1、降低UE最大带宽
为了使RedCap UE和非低能力终端(non-RedCap UE)能够共用相同的同步信号(Synchronization Signal,SS)块或者广播物理信道(Physical Broadcast Channel,PBCH)块、物理资源集合(control-resource set,CORESET)0和系统信息块(System Information Block,SIB)1没实现共存,3GPP通过讨论已同意FR1频段RedCap UE的最大带宽从100MHz降低为20MHz。与此同时,FR2频段RedCap UE的最大带宽降低为100MHz。
2、减少UE Rx天线数量
在要求普通NR UE(即non-RedCap UE)支持最少2个接收天线端口的频段上,对于RedCap UE,其支持的最少接收天线数为1。在这些频段上,RedCap UE的接收天线数也可以为2。
在要求普通NR UE支持最少4个接收天线端口的频段上,对于RedCap UE,其支持的最少接收天线数为1。在这些频段上,RedCap UE的接收天线数也可以为2。
3、减少UE MIMO层数
对于接收天线数为1的RedCap UE,支持1层的下行(Down Link,DL)MIMO。
对于接收天线数为2的RedCap UE,支持2层的DL MIMO。
4、降低最高调制阶数
使用较低的调制阶数可以降低对射频器件和基带芯片处理能力的要求。在SI阶段,针对最高调制 阶数的放松,主要研究了以下选项:
对于上行(Up Link,UL):
-FR1:最高调制阶数从64QAM,降低为16QAM;
-FR2:最高调制阶数从64QAM,降低为16QAM;
对于DL
-FR1:最高调制阶数从256QAM,降低为64QAM;
-FR2:最高调制阶数从64QAM,降低为16QAM。
5、半双工频分双工(Frequency Division Duplexing,FDD)
与全双工FDD相比,采用半双工FDD模式,RedCap UE可以在不同时刻分别在不同频率上进行发送和接收,在实现上可采用成本较低的收-发天先开关和低通滤波器来代替成本较高的双工器。
在LTE中,为UE定义了两种半双工FDD模式:Type A和Type B。考虑到半双工FDD Type B过于复杂,3GPP RAN通过讨论决定Rel-17FDD RedCap UE支持半双工FDD Type B操作。
6、放松终端处理时间
UE从接收物理上行共享信道(Physical Uplink Shared Channel,PDSCH)到发送上行HARQ反馈之间,以及从接收指示上行调度的PDCCH到发送PUSCH之间,均需要一定的处理时间,UE硬件的处理能力越高则该处理时间越短。放松UE处理时间的要求,即允许更长的处理时间,可放松对接收机处理模块的要求,降低UE成本。
7、降低终端强制支持的最大DRB个数
在Rel-15/Rel-16中,UE支持的最大数据无线承载(Data Radio Bearer,DRB)个数为8,并且该能力为UE的必选能力。从目前RedCap支持的三大应用场景来看,UE一般情况下不会同时存在多个并行业务。此外,DRB个数会直接影响到UE缓存区和内存大小。因此,可以考虑通过减少UE支持的最大DRB数量来降低终端成本。
8、降低层2缓存区大小
其中,层2即L2层,L2层包括无线链路控制(Radio Link Control,RLC)层和分组数据聚合协议(Packet Data Convergence Protoco,PDCP)层;
L2缓存区大小主要取决于上下行峰值数量和无线链路控制(Radio Link Control,RLC)往返时间(Round-Trip Time,RTT)。与Rel-15/Rel-16NR UE相比,RedCap UE要求支持的峰值速率有所降低,其L2缓存区大小也可以相应的减小。
9、减小PDCP序列号(Sequence Number,SN)长度,或RLC SN长度;
RLCSN长度或PDCP SN长度,RLC层或PDCP层需要支持的滑动窗窗长相关。在Rel-15/Rel-16中,对于PDCP确认模式(Acknowledged Mode,AM)和RLC AM,必须支持18bit的SN长度。如果RedCap UE的缓存区大小相比Rel-15/Rel-16有所降低,那么对于RedCap UE而言,其不需要强制支持18bit的RLC SN长度,或者,PDCP SN长度。
四、小区禁止(Cellbarred)机制
UE在初始接入阶段,在获得时频域同步后,会先读取主信息块(Master Information Block,MIB)。MIB中包含以下两个与小区选择和重选相关的参数:
cellBarred ENUMERATED(列举){barred(禁止),notBarred(不禁止)};
intraFreqReselection ENUMERATED{allowed(允许),notAllowed(不允许)};
MIB中的cellBarred:用于指示当前小区是否针对所有UE被禁止接入。如果cellBarred指示为barred的话,那么处于RRC_idle和RRC_inactive状态的UE就无法驻留在该小区。
MIB中的intraFreqReselection:用于指示如果当前小区是当前频率的最佳小区,而又不允许UE驻留的时候,是否允许UE选择或者重选到当前频率上的次佳小区上去。
3GPP在Rel-17标准化过程中讨论了要针对RedCap终端引入单独的Cellbarred机制,以便于网络设备针对RedCap UE和non-RedCap UE接入网络可以进行独立的控制。在最近结束的3GPP RAN2#104e次会议中,针对RedCap终端的Cellbarred机制形成以下结论:
1、网络可以通过系统信息块(System Information Block,SIB)1针对接收天线个数为1的RedCap UE和接收天线个数为2的RedCap UE,分别进行小区禁止指示(即cell barring指示)。
2、针对RedCap UE的cell barring是基于每个小区的(不是基于每个PLMN的)。
3、RedCap UE支持频率内重选指示(Intra Frequency Reselection Indicator)。
在sidelink relay场景中,remote UE通过与relay UE通过PC5接口建立连接,从而连接到网络, 如果remote UE为RedCap终端,网络或者relay UE如何针对该remote UE进行接入控制,是需要从标准层面解决的问题。
本发明实施例提供一种接入控制方法,中继终端可以接收网络设备发送的第一信息,第一信息用于禁止第一终端接入,或者,第一信息用于允许第一终端接入,其中,第一终端可以是RedCap终端,和/或,non-RedCap终端,这样网络设备可以通过第一信息去指示是否允许RedCap终端,和/或,non-RedCap终端接入,并且可以使得中继终端在获取第一信息之后,根据第一信息去指示是否允许RedCap终端,和/或,non-RedCap终端接入,从而可以在侧行链路中继场景中,针对remote UE进行接入控制。
本发明实施例中的终端(包括中继终端和远程终端)通常也成为终端设备,本申请实施例结合网络设备和终端设备描述了各个实施例,其中,终端设备也可以称为用户设备(User Equipment,UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置等。
终端设备可以是WLAN中的站点(STAION,ST),可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、下一代通信系统例如NR网络中的终端设备,或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)网络中的终端设备等。

进一步的,若远程终端为第一终端,且上述第二信息用于允许第一终端接入,则远程终端可以根据偏移值对第一信号强度进行修正,得到第二信号强度,该第一信号强度为接收到的中继终端的参考信号强度;若第二信号强度大于或等于接入强度门限,则远程终端接入中继终端,也即此时确定该中继终端为该远程终端提供中继服务。

通过上述方案中,进一步引入偏移值,以及判断修改后的第二信号强度是否大于或等于接入强度门限,在第二信号强度大于或等于接入强度门限情况下远程终端再接入中继终端,可以保证remote UE和relay UE两侧的传输都可以正常进行。
本发明实施例中提供的接入控制方法,
中继终端可以接收网络设备发送的第一信息,第一信息用于禁止第一终端接入,或者,第一信息用于允许第一终端接入,并且可以向远程终端广播根据第一信息确定的第二信息,其中,第一终端可以是RedCap终端,和/或,non-RedCap终端,这样网络设备可以通过第一信息去指示是否允许RedCap终端,和/或,non-RedCap终端接入,并且可以使得中继终端在获取第一信息之后,根据第一信息和自身情况确定第二信息,并通过第二信息去指示是否允许RedCap终端,和/或,non-RedCap终端接入,从而可以在侧行链路中继场景中,针对remote UE进行接入控制。
如图3所示,本发明实施例还提供一种接入控制方法,包括:
301、远程终端接收中继终端发送的参考信号。
302、远程终端确定第一信号强度。
其中,第一信号强度为接收到的中继终端的参考信号强度。
303、远程终端根据偏移值对第一信号强度进行修正,得到第二信号强度。
示例性的,采用第一RSRP表示第一信号强度,第二RSRP表示第二信号强度,则第二RSRP=第一RSRP-offset。
304、若第二信号强度大于或等于接入强度门限,则远程终端接入中继终端。
可选的,上述偏移值可以通过以下至少一种方式确定:
1)网络设备配置;
2)远程终端预配置;
3)根据中继终端与远程终端的功率等级差确定。
示例性的,采用offset标识该偏移值,offset=max(P PowerClass,relay UE–P PowerClass remote UE,0),其中,P PowerClass,relay UE为中继终端的功率等级,P PowerClass remote UE表示远程终端的功率等级。
目前针对非连接态的远程终端(remote UE)选择中继终端(relay UE)时,只考虑了对侧行链路的RSRP测量结果,并没有考虑两侧UE的功率等级差异性导致的侧行链路的两个方向上(上行和下行)的传输覆盖不对称的问题,通过上述方案中,引入偏移值,以及判断修改后的第二信号强度是否大于或等于接入强度门限,在第二信号强度大于或等于接入强度门限情况下远程终端再接入中继终端,可以保证remote UE和relay UE两侧的传输都可以正常进行。
为了进一步说明本发明实施例中的方案,下面将通过5个实施例分别对本发明实施例提供的接入控制方法进行说明,其中下述实施例中,将低能力终端也表示为RedCap终端或RedCap UE;非低能力终端也表示为non-RedCap终端或non-RedCap UE;中继终端(也表示为Relay UE;远程终端也表示为remote UE;小区禁止指示标识为cellBarred指示。
实施例一
针对RedCap终端,使用一个cellBarred指示同时控制是否允许RedCap终端通过Uu接口和PC5接口接入网络的两种接入方式。
示例性的,如图4所示,为一种实施例一对应的示意图,具体实施过程如下:
在系统消息(如SIB1)中,网络设备广播针对RedCap终端的第一小区禁止(cellBarred)指示,该第一cellBarred指示用于指示当前小区针对RedCap UE是否被禁止接入。
针对RedCap终端的第一cellBarred指示可以是针对不同的RedCap终端类型分别配置,比如针对不同的终端接收天线数使用不同的cellBarred指示分别进行控制。
针对RedCap终端的第一cellBarred指示用于同时控制是否允许RedCap终端通过以下两种方式接入网络设备:
方式1:RedCap终端通过Uu接口接入网络设备;
方式2:RedCap终端通过PC5接口接入到中继终端(也表示为Relay UE)。
Relay UE根据自己的终端类型,并结合与自己的终端类型对应的第一cellBarred指示判断,如果该Relay UE为RedCap UE,并且网络设备针对RedCap终端的第一cellBarred指示为“当前小区允许RedCap终端接入”,则该Relay UE可以接入网络设备。
Relay UE通过广播方式下发针对RedCap UE的第二小区禁止(cellBarred)指示,具体方法可以是:
方法1:Relay UE直接转发来自网络设备的针对RedCap UE的第一cellBarred指示,即Relay UE不能更改网络设备广播的针对RedCap UE的第一cellBarred取值。
方法2:Relay UE根据来自网络设备的针对RedCap UE的第一cellBarred指示,同时结合自身的情况,决定其广播的第二cellBarred指示取值。
可选的,如果网络设备广播的针对RedCap UE的第一cellBarred指示为“当前小区禁止RedCap终端接入”,则Relay UE广播的针对RedCap UE的第二cellBarred指示为“当前小区禁止RedCap终端接入”。
可选的,如果网络设备广播的针对RedCap UE的第一cellBarred指示为“当前小区允许RedCap终端接入”,则Relay UE可以根据自身情况确定广播的针对RedCap UE的第二cellBarred指示为“当前小区允许RedCap终端接入”或者“当前小区禁止RedCap终端接入”。
远程终端Remote UE可以根据自己的终端类型结合第二cellBarred指示判断,如果该remote UE为RedCap UE,并且:
如果来自Relay UE的针对RedCap终端的第二cellBarred指示为“当前小区允许RedCap终端接入”,则该remote UE可以通过PC5连接到该Relay UE从而接入网络设备。
如果来自Relay UE的针对RedCap终端的第二cellBarred指示为“当前小区禁止RedCap终端接入”,则该remote UE不能通过PC5连接到该Relay UE从而接入网络设备。
实施例一中方案,针对RedCap UE的通过Uu接入和通过PC5接入这两种接入网络的方式实行统一的控制,不用引入额外的Uu信令参数。
实施例二
针对RedCap终端,使用一个cellBarred指示控制是否允许RedCap终端通过Uu接口接入网络,以及使用另一个cellBarred指示控制是否允许RedCap终端通过PC5接口接入网络。
示例性的,如图5所示,为一种实施例二对应的示意图,具体实施过程如下:
在系统消息(如SIB1或者其他SIB)中,网络广播针对RedCap终端的第三小区禁止(cellBarred)指示和第四小区禁止(cellBarred)指示,第三cellBarred指示用于指示当前小区是否允许RedCap UE通过Uu接口接入到网络,第四cellBarred指示用于指示当前小区是否允许RedCap UE通过PC5接口接入到Relay UE从而接入网络。
针对RedCap终端的第三cellBarred指示和第四cellBarred指示可以是针对不同的RedCap终端类型分别配置,比如针对不同的终端接收天线数使用不同的cellBarred指示分别进行控制。
Relay UE根据自己的终端类型结合第三cellBarred指示判断,如果该Relay UE为RedCap UE,并且网络针对RedCap终端的第三cellBarred指示为“当前小区允许RedCap终端接入”,则该Relay UE可以接入网络。
Relay UE通过广播方式下发针对RedCap UE的第五cellBarred指示,具体方法可以是:
方法1:Relay UE直接转发来自网络的针对RedCap UE的第四cellBarred指示,即Relay UE不能 更改网络广播的针对RedCap UE的第四cellBarred取值。
方法2:Relay UE根据来自网络的针对RedCap UE的第四cellBarred指示,同时结合自身的情况决定其广播的第五cellBarred指示取值。
可选的,如果网络广播的针对RedCap UE的第四cellBarred指示为“当前小区禁止RedCap终端接入”,则Relay UE广播的针对RedCap UE的第五cellBarred指示为“当前小区禁止RedCap终端接入”。
可选的,如果网络广播的针对RedCap UE的第四cellBarred指示为“当前小区允许RedCap终端接入”,则Relay UE可以根据自身情况确定广播的针对RedCap UE的第五cellBarred指示为“当前小区允许RedCap终端接入”或者“当前小区禁止RedCap终端接入”。
Remote UE根据自己的终端类型结合第五cellBarred指示判断,如果该remote UE为RedCap UE,并且:
如果来自Relay UE的针对RedCap终端的第五cellBarred指示为“当前小区允许RedCap终端接入”,则该remote UE可以通过PC5连接到该Relay UE从而接入网络。
如果来自Relay UE的针对RedCap终端的第五cellBarred指示为“当前小区禁止RedCap终端接入”,则该remote UE不能通过PC5连接到该Relay UE从而接入网络。
实施例二中方案,可以针对RedCap UE的通过Uu接入和通过PC5接入这两种接入网络的方式实现更灵活的控制,但需要引入额外的Uu信令参数。
实施例三
对于UE通过PC5接入到Relay UE的情况,网络通过广播的方式为RedCap终端和non-RedCap终端配置不同的发送资源池和/或接收资源池。RedCap终端根据是否存在针对RedCap终端的发送资源池和/或接收资源池配置确定当前小区是否允许RedCap UE通过PC5接口接入到Relay UE从而接入网络。
示例性的,如图6所示,为一种实施例三对应的示意图,具体实施过程如下:
网络通过广播的方式配置PC5的发送资源池和/或接收资源池,发送资源池和/或接收资源池针对RedCap终端和non-RedCap终端分别配置。
针对RedCap终端和non-RedCap终端分别配置的发送资源池和/或接收资源池在时域或频域上没有重叠。
进一步地,针对RedCap终端的发送资源池和/或接收资源池可以是针对不同的RedCap终端类型分别配置,RedCap终端类型的区分方式可以包含不限于以下方式中的一种或者多种:

(2)FR1频段的RedCap UE或者FR2频段的RedCap UE。
(3)RedCap终端场景的区分;例如工业无线传感器,视频监控设备,可穿戴设备
(4)UE的Rx/Tx天线数的区分;
(5)UE的最大带宽的区分,例如对于FR1频段的RedCap UE,还是20MHz,或者是10MHz;
Relay UE根据自己的终端类型结合资源池配置信息判断,如果该Relay UE为RedCap UE,并且网络没有广播针对RedCap终端发送资源池和/或接收资源池,则该UE不能作为Relay UE为其他remote UE提供服务。
Relay UE通过广播方式下发发送资源池和/或接收资源池配置信息,具体方法可以是:
方法1:Relay UE直接转发网络广播的发送资源池和/或接收资源池配置信息,即Relay UE不能更改网络广播的发送资源池和/或接收资源池配置信息。
方法2:Relay UE根据发送资源池和/或接收资源池配置信息,同时结合自身的情况决定其广播的发送资源池和/或接收资源池配置信息。
可选的,如果网络广播的发送资源池和/或接收资源池配置信息中不包含针对RedCap UE的发送资源池和/或接收资源池配置信息,则Relay UE广播的发送资源池和/或接收资源池配置信息中也不包含针对RedCap UE的发送资源池和/或接收资源池配置信息。
可选的,如果网络广播的发送资源池和/或接收资源池配置信息中包含了针对RedCap UE的发送资源池和/或接收资源池配置信息,则Relay UE可以根据自身情况确定其广播的发送资源池和/或接收资源池配置信息中是否包含针对RedCap UE的发送资源池和/或接收资源池配置信息。
Remote UE根据自己的终端类型结合Relay UE广播的发送资源池和/或接收资源池配置信息判断,如果该remote UE为RedCap UE,并且:
如果来自Relay UE的发送资源池和/或接收资源池配置信息中包含了针对RedCap UE的发送资源池和/或接收资源池配置信息,则该remote UE可以通过PC5连接到该Relay UE从而接入网络。
如果来自Relay UE的发送资源池和/或接收资源池配置信息中没有包含针对RedCap UE的发送资源池和/或接收资源池配置信息,则该remote UE不能通过PC5连接到该Relay UE从而接入网络。
实施例三中方案,针对RedCap UE通过PC5接入提供了一种隐式的接入控制方式,通过资源池指示来隐式指示。
实施例四
对于UE通过PC5接入到Relay UE的情况,网络通过广播的方式为RedCap终端和non-RedCap终端配置不同的发送资源池和/或接收资源池。Relay UE通过广播方式下发针对RedCap UE的第六cellBarred指示。Remote RedCap终端根据第六cellBarred指示确定当前小区是否允许RedCap UE通过PC5接口接入到Relay UE从而接入网络。

Relay UE根据自己的终端类型结合资源池配置信息判断,如果该Relay UE为RedCap UE,并且网络没有广播针对RedCap终端发送资源池和/或接收资源池,则该UE不能作为Relay UE为其他remote UE提供服务。
Relay UE通过广播方式下发针对RedCap UE的第六cellBarred指示,具体方法可以是:
方法1:Relay UE只根据网络广播的发送资源池和/或接收资源池配置信息确定针对RedCap UE的第六cellBarred指示。
如果网络广播的发送资源池和/或接收资源池配置信息中不包含针对RedCap UE的发送资源池和/或接收资源池配置信息,则Relay UE广播的针对RedCap UE的第六cellBarred指示为“当前小区禁止RedCap终端接入”。
如果网络广播的发送资源池和/或接收资源池配置信息中包含针对RedCap UE的发送资源池和/或接收资源池配置信息,则Relay UE广播的针对RedCap UE的第六cellBarred指示为“当前小区允许RedCap终端接入”。
方法2:Relay UE根据网络广播的发送资源池和/或接收资源池配置信息,同时结合自身的情况决定其广播的第六cellBarred指示取值。具体的:
如果网络广播的发送资源池和/或接收资源池配置信息中不包含针对RedCap UE的发送资源池和/或接收资源池配置信息,则Relay UE广播的针对RedCap UE的第六cellBarred指示为“当前小区禁止RedCap终端接入”。
如果网络广播的发送资源池和/或接收资源池配置信息中包含针对RedCap UE的发送资源池和/或接收资源池配置信息,则Relay UE可以根据自身情况确定其广播的针对RedCap UE的第六cellBarred指示为“当前小区允许RedCap终端接入”还是“当前小区禁止RedCap终端接入”。
Remote UE根据自己的终端类型结合第六cellBarred指示判断,如果该remote UE为RedCap UE,并且:
如果来自Relay UE的针对RedCap终端的第六cellBarred指示为“当前小区允许RedCap终端接入”,则该remote UE可以通过PC5连接到该Relay UE从而接入网络。
如果来自Relay UE的针对RedCap终端的第六cellBarred指示为“当前小区禁止RedCap终端接入”,则该remote UE不能通过PC5连接到该Relay UE从而接入网络。
实施例四中方案,提供了一种隐式和显式相结合的接入控制方式。可以理解的是,针对上述实施例一至实施例4中所涉及的第一cellBarred指示、第二cellBarred指示、第三cellBarred指示、第四 cellBarred指示以及第五cellBarred指示的描述,是为了区别cellBarred指示,并不是针对cellBarred指的顺序的限定。
实施例五
处于非连接态的remote UE在选择服务Relay UE时,考虑自己的功率等级。
remote UE对来自Relay UE的参考信号进行测量,得到Remote UE根据侧行链路测量结果第一RSRP(即第一参考信号的信号强度),并对第一RSRP进行修正,得到第二RSRP
其中,上述参考信号可以为:发现(discovery)信号或数据信号。
第二RSRP=第一RSRP-offset,其中,offset的确定方法可以包括但不限于以下几种:
方法1:网络配置;
方法2:在remote UE中预配置的方式;
方法3:remote UE根据自己与Relay UE的功率等级差确定:offset=max(P PowerClass,Relay UE–P PowerClass  remote UE,0),其中,P PowerClass,relay UE为中继终端的功率等级,P PowerClass remote UE表示远程终端的功率等级。
Remote UE根据修正后的RSRP判断:如果修正后的第二RSRP大于RSRP门限,则remote UE选择该Relay UE作为服务中继。
目前标准中讨论的针对非连接态的remote UE选择Relay UE时,只考虑了对侧行链路的RSRP测量结果,并没有考虑两侧UE的功率等级差异性导致的侧行链路的两个方向上的传输覆盖不对称的问题,实施例五的方案,可以保证选择到可以实现正常的双向传输的中继终端进行接入。
