非授权频段是解决移动通信网络频谱资源紧张的有效方法之一,通过将授权频段的新无线(New Radio,NR)技术扩展到非授权频段,可以提升***的容量和性能。
在NR***中,非授权频段主要在5GHz,37GHz和60GHz频段。然而非授权频段上运行着多种不同无线接入技术的设备,例如无线路由器,雷达,蓝牙设备等,因此,工作在非授权频段的设备需要采用基于竞争的分布式协调接入方式,例如“说之前听”(Listen Before Talk,LBT)过程。要进行数据传输的发送节点(网络设备或者终端设备)在使用非授权频段时需要先侦听信道,只有当发送节点在一定时间段内持续地侦听到信道保持空闲时才能发送数据。
由于非授权频段属于共享频段,网络设备可能因为信道忙而在某一些周期无法发送周期性的参考信号,在这种情况下,终端设备在进行无线链路的测量过程中,因每个周期都需要进行状态指示上报,例如,失步(Out-Of-Sync,OOS)指示、波束失败事件(Beam Failure Instance,BFI)指示,层间交互开销大。

应理解,本公开的一些实施例的技术方案可以应用于各种通信***,例如:长期演进(Long Term Evolution,LTE)***、LTE频分双工(Frequency Division Duplex,FDD)***、LTE时分双工(Time Division Duplex,TDD)、通用移动通信***(Universal Mobile Telecommunication System,UMTS)或全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信***、5G***,或者说新无线(New Radio,NR)***,或者为后续演进通信***。
在本公开的一些实施例中,终端设备可以包括但不限于移动台(Mobile Station,MS)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、用户设备(User Equipment,UE)、手机(handset)及便携设备(portable equipment)、车辆(vehicle)等,该终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,例如,终端设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等,终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
本公开的一些实施例中,网络设备是一种部署在无线接入网中用以为终端设备提供无线通信功能的装置。所述网络设备可以为基站,所述基站可以包括各种形式的宏基站,微基站,中继站,接入点等。在采用不同的无线接入技术的***中,具有基站功能的设备的名称可能会有所不同。例如在LTE网络中,称为演进的节点B(Evolved NodeB,eNB或eNodeB),在第三代(3rd Generation,3G)网络中,称为节点B(Node B),或者后续演进通信***中的网络设备等等,然用词并不构成限制。
如图1所示,本公开的一个实施例提供一种无线链路状态指示上报方法100,该方法可以由终端设备执行,包括如下步骤:
S102:检测参考信号。
该实施例执行之前,网络设备可以为每个非授权频段的部分带宽(BandWidth Part,BWP)上配置Y个周期性发送的参考信号,这样,终端设备即可在每个时间周期检测上述参考信号,其中,Y可以是1或2等正整数。
上述参考信号可以是信道状态信息参考信号(Channel State Information-Reference Signal,CSI-RS)或同步信号块(Synchronization Signal&PBCH Block,SSB)等。
该步骤中检测参考信号,具体可以是在每个时间周期检测参考信号信干噪比(Signal to Interference and Noise Ratio,SINR);参考信号接收功率(Reference Signal Receiving Power,RSRP);参考信号接收质量(Reference Signal Receiving Quality,RSRQ);或误块率(Block Error Rate,BLER);或接收信号强度指示(Received Signal Strength Indicator,RSSI);信道繁忙率(Channel Busy Ratio,CBR);信道占用(Channel Occupancy,CO);等。
S104:如果在N个连续的时间周期未检测到参考信号,则向高层上报一个状态指示。
其中,N为正整数,且N≥(大于或等于)2,例如,N可以是2、或3或4等。
该步骤中在N个连续的时间周期未检测到参考信号,具体可以是N个时 间周期内的所有参考信号的检测值均低于预设阈值。具体例如,网络设备在每个时间周期配置2个参考信号,在N个时间周期中,每个时间周期内的2个参考信号的检测值均低于上述预设阈值。
具体地,在S104中,例如,N=3,终端设备在3个连续的时间周期(称为为第一时间周期至第三时间周期)未检测到参考信号,则在第三时间周期上报一个状态指示;在后续相邻的3个连续的时间周期(第四时间周期至第六时间周期)仍然未检测到参考信号,因此在第六时间周期也需要上报一个状态指示,后续的过程类似,其中,在第四时间周期和第五时间周期不会上报状态指示。
可选地,在上述实施例中,如果在小于N个的连续的时间周期未检测到参考信号,则不向高层上报状态指示。具体如图2所示,终端设备在1个时间周期未检测到配置的2个参考信号,则不向高层上报状态指示,该实施例中,每个时间周期配置2个参考信号。
在本公开的一些实施例中,终端设备检测参考信号,如果在N个连续的时间周期未检测到参考信号,则向高层上报一个状态指示,N为正整数,且N≥2,本公开的一些实施例充分考虑了网络设备可能因为信道忙而在某些时间周期无法发送参考信号的情形,有利于减少层间交互。
在一个具体的实施例中,如图3所示,该实施例中的N为3,每个时间周期配置2个参考信号,终端设备在3个连续的时间周期都未检测到全部配置的参考信号,因此向高层上报一个状态指示。
上述实施例100介绍了如果在N个连续的时间周期都未检测到参考信号,向高层上报一个状态指示的情形,该一个状态指示可以是以下四者中的一种:
1)失步(Out-Of-Sync,OOS)指示;或
2)波束失败事件(Beam Failure Instance,BFI)指示;
3)第一指示;或
4)第二指示。
以下将分不同的场景,对上述上报的状态指示的情况分别进行介绍。
实施例一:
如果在N个连续的时间周期内参考信号的检测值均低于第一阈值,向高 层上报失步OOS指示。
实施例二:
如果在N个连续的时间周期内参考信号的检测值低于第一阈值但高于或等于第二阈值,则向高层上报OOS指示;以及
如果在N个连续的时间周期内参考信号的检测值低于第二阈值,则向高层上报第一指示。
实施例三:
如果在N个连续的时间周期参考信号的检测值低于第三阈值,则向高层上报波束失败事件BFI指示。
实施例四:
如果在N个连续的时间周期参考信号的检测值低于第三阈值但高于或等于第四阈值,则向高层上报BFI指示;以及
如果在N个连续的时间周期所述参考信号的检测值低于第四阈值,则向高层上报第二指示。
上述实施例一和实施例二具体可以应用在无线链路监测(Radio link monitoring,RLM)场景中,可选地,如果在某一个时间周期内的参考信号的检测值高于第六阈值,则向高层上报一个同步IS指示。该处提到的一个时间周期内的参考信号的检测值高于第六阈值,具体可以是一个时间周期配置的多个参考信号中,任意一个参考信号的检测值高于第六阈值。
上述实施例一和实施例二中,各个阈值的大小关系从高到底为:第六阈值、第一阈值以及第二阈值。
上述实施例三和实施例四具体可以应用在波束失败检测(Beam failure detection,BFD)场景中。
上述实施例三和实施例四中,第三阈值以及第四阈值。
上述实施例一和实施例二介绍了上报状态指示的情况,可选地,在一个实施例中,上述在N个连续的时间周期都未检测到参考信号,物理层向高层上报一个状态指示可以是第一指示,这样,终端设备还可以在高层中统计第一指示连续出现的次数;根据第一指示续出现的次数,确定是否启动无线链路监测定时器T310;或者,检测是否发生无线链路失败(Radio link failure, RLF),关于T310和RLF的详细作用可以参见相关技术。
可选地,在高层中统计第一指示连续出现的次数的过程中,目标指示对于第一指示连续性统计没有影响;其中,目标指示是与同步IS指示不同的指示,目标指示可以是OOS指示、空指示等。该处提到的空指示,例如,在某一个时间周期内参考信号的检测值高于第一阈值但低于第六阈值,则可以向高层上报一个空指示,当然,空指示还可以用其他术语来表示。
具体可以参见图4和图5,图4中,忽略的目标指示是失步OOS指示、空指示,因此,图4所示的实施例中统计的DL LBT失败指示连续出现的次数为3次;在图5中,因出现了同步指示,因此,统计的DL LBT失败指示连续出现的次数为2次。
上述实施例三和实施例四介绍了上报状态指示的情况,可选地,在一个实施例中,上述在N个连续的时间周期都未检测到参考信号,物理层向高层上报一个状态指示可以是第二指示,这样,终端设备若高层接收到第二失败指示,则启动或重启目标定时器;在所述目标定时器运行期间,每次在高层接收到一个第二指示,对目标计数器的计数值累加一个计数单位;其中,所述目标计数器的计数值用于确定是否触发随机接入。
具体例如,如果目标计数器的计数值大于或等于第五阈值,则触发随机接入;如果目标计数器的计数值小于第五阈值,则不触发随机接入。
对于上述提到的目标定时器,具体可以在满足下述条件的至少之一的情况下,重置所述目标计数器的计数值;
1)波束失败检测定时器beam failure detection timer超时;
2)波束失败检测最大计数被重新配置;
3)上述目标定时器超时;
4)上述目标定时器的时长被重新配置;
5)上述第五阈值被重新配置;
6)S102中检测的参考信号被重新配置;以及
7)上述触发的随机接入过程成功完成。
可选地,在上述多个实施例的S102测量参考信号之前,还可以包括如下步骤:接收配置信息;根据所述配置信息对下述至少一种信息进行配置;
参数N;
第一阈值;
第二阈值;
第三阈值;
第四阈值;
第五阈值;
第六阈值;以及
所述目标定时器的时长。
可以理解,上述配置信息是通指各种类型或种类的配置信息,当然,上述不同的信息还可以是由不同的配置信息来配置,例如,参数N可以根据第一配置信息进行配置;第一阈值和第二阈值可以根据第二配置信息进行配置等等。
可选地,上述参数N;第一阈值;第二阈值;第三阈值;第四阈值;第五阈值;第六阈值;以及所述目标定时器的时长中的至少之一还可以是协议约定的。
为详细说明本公开的一些实施例提供的无线链路状态指示上报方法,以下将结合一个具体的实施例进行说明,该实施例200包括如下步骤:
S202:接收配置信息,并根据配置信息进行相关配置。
该实施例中,网络设备可以向终端设备广播无线链路监测(Radio link monitoring,RLM)和波束失败检测(Beam failure detection,BFD)相关的配置信息,配置信息中包括但不限于下述至少一种:
1)若干个连续的时间周期的具体数值(例如,n4代表自然数4),或上述具体数值的索引。该处若干个连续的时间周期的具体数值,对应于前文中的参数N。
2)判断未检测到参考信号的门限值或者上述门限值的索引,该处提到的门限值,对应于前文中的第一阈值、第二阈值、第三阈值和第四阈值。
3)RLMBLER pair配置或者上述配置的索引,该RLM BLER pair配置包括了用于评估信道质量相关的第一阈值,第二阈值,第六阈值的一组或多组配置,所述索引用于指示终端使用哪套配置,例如,索引1表示使用第一 套配置。4)DL LBT failure counter的最大值,也即前文中提到的第五阈值。该实施例中DL LBT failure counter对应于前文中的目标计数器,该DL LBT failure counter和下述DL LBT failure detection timer配合使用,DL LBT failure counter的计数值用于确定是否触发随机接入。
5)DL LBT failure detection timer的时长,该处的DL LBT failure detection timer timer对应于前文中的目标定时器。
S204:检测参考信号。
终端设备在SpCell(主小区+辅小区)当前激活的BWP上进行RLM和BFD中的至少一种。
S2041:在小于N个的连续的时间周期(indication period)内检测到所有的参考信号的检测值都低于门限值,终端设备的物理层不向高层上报任何状态指示,如图2所示。
其中,参考信号的检测值可能是SINR,RSRP或RSRQ,BLER,RSSI,CBR,CO,上述门限值是基于假设(hypothetical)物理下行控制信道(Physical Downlink Control CHannel,PDCCH)传输参数而得到。
N为正整数,且N≥(大于或等于)2。
可选地,在其它的实施例中,S2041可以变为在小于N个的时间周期内检测到所有的参考信号的BLER都高于预设值等。
S2042:在N个连续的时间周期(indication period)内检测到所有的参考信号的检测值都低于门限值,终端设备的物理层向高层上报一个OOS指示、BFI指示或DL LBT失败指示。
关于在何种情况下上报什么类型的状态指示,具体可以参见前文中的实施例一到实施例四。
S206:终端设备的高层(RRC层)统计DL LBT失败指示连续出现。
该步骤对应于前文实施例一和实施例二的情形,且该步骤假设S2042上报的是第一指示,在高层中统计第一指示连续出现的次数的过程中,目标指示对于第一指示连续性统计没有影响;其中,目标指示可以称作是非In-sync指示。物理层上报的任何非In-sync指示不会影响统计第一指示出现连续性的次数,如图4和图5所示的实施例。
S208:确定是否触发随机接入过程。
该步骤对应于前文实施例三和实施例四的情形,且该步骤假设S2042上报的是DL LBT失败指示(对应与前文中的第二指示),对于BFD过程,如果终端设备的高层收到来自物理层的DL LBT失败指示,启动或者重启动DL LBT failure dectection Timer,并对DL LBT failure counter进行加1,如果该DL LBT failure counter的值大于等于第五阈值,则在SpCell上触发随机接入过程。
该处的DL LBT failure dectection Timer对应与前文中的目标定时器;DL LBT failure counter对应与前文中的目标计时器。
可选地,该实施例中,在满足下述条件的至少之一的情况下,重置DL LBT failure counter的计数值,具体可以是将计数值重置为0:
1)波束失败检测定时器beam failure detection timer超时;
2)波束失败检测最大计数被重新配置;
3)LBT failure dectection Timer超时;
4)LBT failure dectection Timer的时长被重新配置;
5)所述第五阈值被重新配置;
6)所述参考信号被重新配置;以及
7)所述随机接入过程成功完成。
在本公开的一些实施例中,终端设备检测参考信号,如果在N个连续的时间周期未检测到所述参考信号,则向高层上报一个状态指示,N为正整数,且N≥2,本公开的一些实施例充分考虑了网络设备可能因为信道忙而在某些时间周期无法发送参考信号的情形,有利于减少层间交互。
另外,本公开的一些实施例能够在LBT failure counter的值大于等于第五阈值的情况下,在SpCell上触发随机接入过程,改善终端和网络设备的波束配对,提高通信有效性。
