(2)圆形螺旋式波束具有多方向电磁场,电磁场范围较宽泛,但相对线极化天线而言强度较小。
圆极化天线的圆形电磁波束能够同时向各个方向发送。当遇到障碍时,圆极化天线的电磁波束具有较强的弹性和绕行能力;但是圆形波束的宽泛也带来了电磁波强度的相
对降低。
线极化天线发出的电磁波是线性的,其电磁场具有较强方向性,具有以下特点:
(1)无线射频能量以线性的方式从天线发射;
(2)线性波束具有单方向的电磁场,相对圆极化天线而言电磁场较强,但范围较窄长。
圆极化波在穿越雨雾层和电离层时,损耗少,也不存在线极化极化面旋转的问题。
网络可以在非***信息块1(system information block 1,SIB1)的其他***信息(other system information,OSI)里,可以指定一个公共的极化(polarization),通知所有UE网络(如,卫星)在下行发送和上行接收使用的polarization类型,具体如下表1所示;
表1
上行功率控制
在NR中,gNB确定期望的上行链路发射功率,并向UE提供上行链路发射功率控制命令。UE使用所提供的上行链路发射功率控制命令来调整其发射功率。
基于下行链路参考信号估计的路径损耗是调整上行链路功率的重要因素之一。例如,对于用于定位的探测参考信号(Sounding Reference Signal,SRS)传输,以下方式用于确定SRS的传输功率:
如果UE基于在服务小区c的载波f的激活UL BWP b上设置的SRS-PosResourceSet的配置来发送SRS,则UE将SRS发送场合i中的SRS发送功率PSRS,b,f,c(i,qs)确定为:
-PO_SRS,b,f,c(qs)和αSRS,b,f,c(qs)分别由p0-r16和alpha-r16提供,用于服务小区c的载波f的激活UL BWP b上,SRS资源集qs由SRS-PosResourceSet中的SRS-PosResourceSetId指示,以及
PLb,f,c(qd)是在服务小区c的激活DL-部分带宽(Bandwidth Part,BWP)的情况下,
由UE使用服务或非服务小区中针对SRS资源集qs的RS资源索引qd来计算的下行链路路径损耗估计,以dB为单位。与SRS资源集qs关联的RS资源索引qd的配置由pathlossReferenceRS-Pos提供。
-如果提供了ssb-IndexNcell,则referenceSignalPower由ss-PBCH-BlockPower-r16提供;
-如果提供了dl-PRS-ResourceId,则referenceSignalPower由dl-PRS-ResourcePower提供;
如果UE确定UE不能准确地测量PLb,f,c(qd),或者UE没有配备pathlossReferenceRS-Pos,则UE使用从UE用于获取管理信息库(Management Information Base,MIB)的服务小区的同步信号(Synchronization Signal,SS)/物理广播信道(Physical Broadcast Channel,PBCH)块获得的RS资源来计算PLb,f,c(qd);
除了UE为每个服务小区为物理上行共享信道(Physical Uplink Shared Channel,PUSCH)/物理上行控制信道(Physical Uplink Control Channel,PUCCH)传输和由SRS-Resource配置的SRS传输维护的多达四个路径损耗估计之外,UE还可以指示用于多个路径损耗估计的能力,该路径损耗估计是UE可以同时为SRS-PosResourceSet提供的所有SRS资源集维护的。
当前支持的定位技术
NG无线接入网(NG Radio Access Network,NG-RAN)可以使用一种或多种定位方法来确定UE的位置。
定位UE包括两个主要步骤:
(1)信号测量;和
(2)基于测量的位置估计和可选速度计算。
信号测量可由UE或由服务ng eNB或gNB进行。为地面定位方法测量的基本信号通常是LTE或NR无线电传输;然而,其他方法可以利用其他传输,例如通用无线电导航信号,包括来自全球导航卫星***(Global Navigation Satellite System,GNSS)的信号。
定位功能不应局限于单一方法或测量。也就是说,它应该能够利用其他标准方法和测量,因为这些方法和测量是可用的和适当的,以满足定位服务客户的所需服务需求。这些附加信息可能包括随时可用的演进通用移动通信***陆地无线接入网(Evolved UMTS Terrestrial Radio Access Network,E-UTRAN)或NG-RAN测量。
位置估计计算可由UE或定位管理功能(location management function,LMF)进行。
NG-RAN接入支持的标准定位方法有:
(1)网络辅助的全球导航卫星***(Global Navigation Satellite System,GNSS)方法;
(2)基于LTE信号的观测到达时间差(Observed Time Difference of Arrival,OTDOA)定位;
(3)基于LTE信号的增强小区ID方法;
(4)无线局域网定位;
(5)蓝牙定位;
(6)地面信标***(Terrestrial Beacon System,TBS)定位;
(7)基于传感器的方法:
(8)气压传感器;
(9)运动传感器。
(10)基于NR信号的NR增强小区ID方法(NR E-CID);
(11)多往返时间定位(基于NR信号的多RTT);
(12)基于NR信号的下行偏离角(DL AoD);
(13)基于NR信号的下行到达时差(DL-TDOA);
(14)基于NR信号的上行到达时差(UL-TDOA);
(15)上行到达角(UL AoA),包括基于NR信号的A-AoA和Z-AoA。
还支持使用上述定位方法列表中的多种方法进行混合定位。
还支持使用上述定位方法列表中的一种或多种方法的独立模式(例如,自主、无网络协助)。
支持的UE定位方法版本如表2所示:
表2
在独立模式下,也支持基于MBS信号的传感器、WLAN、蓝牙和TBS定位方法。
NR增强的单元ID方法
NR增强小区ID(NR E CID)定位指使用附加UE测量和/或gNB测量来改进UE位置估计的技术。
尽管NR E-CID定位可以使用与RRC协议中的测量控制***相同的一些测量,但UE通常不会仅为定位目的进行额外测量;i、例如,定位过程不提供测量配置或测量控制消息,并且UE报告其可用的测量,而不是被要求采取额外的测量动作。
多往返时间(Round Trip Time,RTT)定位
多RTT定位方法利用UE测量的从多个TRP接收的下行链路信号的UE Rx Tx时差测量值和DL-PRS-RSRP,以及在从UE发送的上行链路信号的多个TRP处测量的gNB Rx Tx时差测量值和UL-SRS-RSRP。
UE使用从定位服务器接收的辅助数据测量UE Rx Tx时差测量(以及可选的接收信号的DL-PRS-RSRP),TRP使用从定位服务器接收的辅助数据测量gNB Rx Tx时差测量(以及可选的接收信号的UL-SRS-RSRP)。测量用于确定定位服务器处的RTT,该RTT用于估计UE的位置。
DL AoD定位
DL-AoD定位方法利用在UE处从多个tp接收的下行链路信号的测量DL-PRS-RSRP。UE使用从定位服务器接收的协助数据来测量所接收信号的DL-PRS-RSRP,并且所得测量与其他配置信息一起使用,以相对于相邻TPs定位UE。
DL-TDOA定位
DL-TDOA定位方法利用在UE处从多个TPs接收的下行链路信号的DL-RSTD(以及可选的DL-PRS-RSRP)。UE使用从定位服务器接收的协助数据来测量接收信号的DL-RSTD(以及可选的DL-PRS-RSRP),并且所得测量与其他配置信息一起使用,以相对于相邻TPs定位UE。
UL-TDOA定位
UL-TDOA定位方法在从UE发送的上行链路信号的多个RPs处使用UL-RTOA(以及可选的UL-SRS-RSRP)。RPs使用从定位服务器接收的辅助数据来测量所接收信号的UL-RTOA(以及可选的UL-SRS-RSRP),并且所得到的测量与其他配置信息一起用于估计UE的位置。
UL AoA
UL-AoA定位方法利用从UE发送的上行链路信号的多个RPs处测量的方位角(A-AoA)和天顶角(Z-AoA)。RPs使用从定位服务器接收的协助数据来测量接收信号的A-AoA和Z-AoA,并且所得测量与其他配置信息一起用于估计UE的位置。
目前在NR中引入了NTN场景。NTN的发射端和接收端可以使用不同的极化类型,包括左圆极化、右圆极化和线性极化。
如果假设的接收极化和发送极化不同,接收端估计的路径损耗可能不准确,例如,当参考信号的发射机使用左圆极化,而接收机侧使用右圆极化时,由于接收到的信号可能不包含发送信号,估计的RSRP可能很低,这意味着估计的路径损耗可能接近TX功率而不是实际路损。对于上行链路传输的功率控制,如果UL传输使用与gNB侧的下行链路接收相同的极化,而上行链路接收使用与卫星中的下行链路传输相同的极化,则使用这样的路径损耗可以间接补偿由于发送端和接收端极化差异而造成的功率损耗。然而,由于RSRP较大,终端可能会被迫使用最大功率,这将导致终端功率损耗会很大。
另一方面,在定位场景中,对参考信号进行测量以估计出卫星和UE之间的距离或时间,需要准确估计实际路径损耗和路径延时,而不会因极化差异而造成损失。
根据上文,用于路径损耗估计或定位测量的RS,当其发射机和接收机中使用不同的极化时,可以改变为其他信号,以便发射机和接收机中使用相同的极化,或者允许使用不同极化方向收发信号,但是需要通过某种方法补偿一些极化损耗。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的信号极化处理方法进行详细地说明。
参见图2,本申请实施例提供一种信号极化处理方法,包括:
步骤201:第一设备接收来自第二设备的第一信号,第一信号是第二设备按照第一预设规则和/或信令配置发送的;即第二设备发送第一信号时,其使用的极化类型可以按照第一预设规则确定,或者通过引入的信令进行配置。
步骤202:第一设备执行以下任意一项:
(1)第一设备根据第二预设规则调整向第二设备发送第二信号时使用的极化类型;
(2)第一设备进行补偿处理;
(3)第一设备接收来自第二设备的满足预设条件的第三信号;
其中,第一预设规则用于第二设备确定发送第一信号时使用的极化类型,第二预设规则用于第一设备确定发送第二信号时使用的极化类型。
上述极化类型可以对应不同方向的极化,例如:左旋圆极化、左旋圆极化、线极化
等。
在本申请实施例中,第一设备和第二设备是信号收发通信两端的设备,具体地,第一设备是第一信号的接收设备,第二设备时第一信号的发送设备;该第一设备和第二设备具体可以是终端也可以是网络侧设备,例如第一设备可以是终端11,第二设备可以是网络侧设备,或者第一设备可以是网络侧设备,第二设备可以是终端,后文在具体描述实施例的过程中,为描述方便,统一按照第一设备可以是终端。第二设备可以是基站的示例进行描述,可以理解的是,本申请实施例对第一设备和第二设备的具体类型不做限定。
当信号收发两端的第一设备和第二设备中使用不同的极化时,可以将接收信号改变为其他信号,以便第一设备和第二设备合理调整极化类型,或者补偿一些极化损耗,从而达到允许使用不同极化收发的信号,避免由极化不同导致的检测偏差。例如在根据估算的路损确定的终端发送功率的情况下,采用本申请的方案,可以防止收发的信号使用的极化不同所导致的路损估算偏差,能够让路损估算准确,从而确定更为准确的终端功率消耗;又例如在进行定位检测的情况下,采用了本申请的方案,可以防止收发的信号使用的极化不同所导致的检测偏差,让定位检测更为准确。
在一种可能的实施方式中,第一预设规则,包括以下任意一项:
(1)第二设备发送第一信号时使用的极化类型,与第二设备发送的***消息中指示的极化类型相同;
(2)第二设备发送第一信号时使用的极化类型,与第二设备发送***消息时使用的极化类型相同。
在本申请实施例中,对发送设备,即第二设备在发送信号时使用的极化类型进行预先规则设置。例如:基站会通过***消息(SIB1和/或OSI)指示一个极化类型,那么规定基站在发送第一信号的时候,所使用的极化类型应当与***消息中指示的极化类型相同;或者,规定基站在发送第一信号的时候,所使用的极化类型应当与第二设备发送***消息时使用的极化类型相同。
这样有了预先对第二设备的极化类型的规定,第一设备就可以基于***消息中指示的极化类型或发送***消息时使用的极化类型获知第二设备发送第一信号时使用的极化类型,从而使用相同的极化类型进行信号接收,避免在信号接收、检测过程中造成偏差。
在一种可能的实施方式中,方法还包括:
第一设备接收来自第二设备的第一信令,第一信令用于指示第二设备发送第一信号时使用的极化类型。
在本申请实施例中,第二设备发送第一信号时,其使用的极化类型可以通过引入的信令(即第一信令)进行配置,那么相应地,第二设备将第一信令发送给第一设备,第一设备基于第一信令的指示能够获知第二设备发送第一信号时使用的极化类型。
在一种可能的实施方式中,第一信令对第一信号所用资源所在的资源集合进行统一指示,即第一信令具体可以是对整个资源集合进行指示,对于该资源集合的所有资源上的第
一信号的极化类型做一个统一指示;或者,第一信令对第一信号所用的资源所在的资源集合中的每个资源进行独立指示,即第一信令具体可以是对整个资源集合中的每个资源上的第一信号的极化类型进行分别指示,从而可以让每个资源上的第一信号的极化类型相同或不同。
在一种可能的实施方式中,第一设备根据第二预设规则调整向第二设备发送第二信号时使用的极化类型,包括:
第一设备将发送第二信号时使用的极化类型,调整至与第一设备接收第一信号时使用的极化类型相同。
在本申请实施例中,第一设备将上行传输使用的极化类型与接收下行信号使用的极化类型调整至相同,这样对于需要根据第一信号估计路损(pathloss)的情况,估计出来的pathloss在收发极化类型不同的情况下会由于极化loss而变大,从而间接使得极化loss在上行发送功率上得到补偿。
在一种可能的实施方式中,第一设备进行补偿处理,包括:
第一设备在接收和/或测量第一信号之后,根据预设补偿进行补偿处理。
在本申请实施例中,允许发送端和接收端使用不同的polarization,并引入预设补偿(例如功率补偿或者定位信息度量补偿)。
在一种可能的实施方式中,预设补偿通过以下一项或者多项确定:
(1)预先确定;
(2)预设场景,比如地球静止轨道(The Geostationary Orbit,GEO)场景和近地轨道(Low Earth Orbit,LEO)场景可以不同;
(3)第一设备接收信号时使用的极化类型和第一设备发送信号时使用的极化类型的组合;
(4)第一设备接收信号时使用的极化类型和第二设备发送信号时使用的极化类型的组合。
在一种可能的实施方式中,上述第三信号满足的预设条件包括以下一项或者多项:
(1)测量第三信号得到的测量度量大于或等于预设阈值;测量度量可以是参考信号接收功率(Reference Signal Receiving Power,RSRP)、参考信号接收质量(Reference Signal Receiving Quality,RSRQ)等等,例如预设条件是测量第三信号得到的RSRP大于或等于预设阈值。
(2)第二设备发送第一信号时使用的极化类型,与第二设备发送的***消息中指示的极化类型相同。
在一种可能的实施方式中,第一设备接收来自第二设备的满足预设条件的第三信号,包括:
在第二设备发送第一信号时使用的极化类型与第二设备发送的***消息中指示的极化类型不同的情况下,第一设备接收来自第二设备的满足预设条件的第三信号。
在一种可能的实施方式中,方法还包括:
第一设备根据第三信号,执行以下一项或者多项:
(1)第二信号的功率确定;
(2)路损确定;
(3)定位相关信息确定;
(4)定位确定。
在一种可能的实施方式中,方法还包括:
第一设备使用预配置或预定义的第二信号的发送功率或者路损。比如,第一设备直接使用允许的最大power发送信号。
在一种可能的实施方式中,第一设备使用预配置或预定义的第二信号的发送功率或者路损,包括:
在第二设备发送第一信号时使用的极化类型与第一设备接收第一信号时使用的极化类型不同的情况下,第一设备使用预配置或预定义的第二信号的发送功率或者路损。
在一种可能的实施方式中,第一信号用于估计路损,路损用于确定第二信号的发送功率。
在一种可能的实施方式中,第一信号和第二信号包括以下一项或者多项:
(1)探测参考信号(Sounding Reference Signal,SRS);
(2)同步信号和物理广播信道块(Synchronization Signal and PBCH block,SSB);
(3)定位参考信号(Positioning Reference Signal,PRS);
(4)信道状态信息参考信号(Channel State Information-Reference Signal,CSI-RS)。
下面结合具体应用示例,对本申请实的技术方案进行描述:
示例一:信号极化确定
在一些实施例中,用于测量的信号,比如SSB/CSI-RS/SRS/PRS,其极化类型跟***消息里指示的polarization相同。
在这种情况下,当UE从***消息获取到卫星所用的polarization信息后,可以调整接收下行信号和发送上行信号的极化类型。
比如可以规定:UE不期望接收到SSB的极化方向与对应SIB中指示的极化方向不同。
在一些实施例中,SSB的极化方向与对应的SIB1和或OSI具有相同的发送极化方向。
比如,能够接收到LHCP(左旋圆极化)SSB的UE,对应地收到的SIB1和或后续的OSI,都是使用LHCP发送的;能够接收到RHCP SSB的UE,对应地收到的SIB1和或后续的OSI,都是使用RHCP发送的
在一些实施例中,对于NTN场景,可以引入per SSB/CSI-RS/SRS的信令配置polarization信息。
比如,对于用于定位的SRS resource set,可以引入ntnPolarization参数用于确定其发送所使用的polarization类型,例如:
或者,对于用于定位的每个SRS resource,可以引入ntnPolarization参数用于确定其发送所使用的polarization类型,例如:
在某些实施例中,如果用于估计pathloss的下行信号(比如SSB或者CSI-RS)所使用的极化类型跟***消息里指定的polarization类型不同时,可以使用如下一种或者多种方法:
(1)重新选择一个下行信号用于pathloss估计,这里的下行信号需要满足如下至少一种条件
(1.1)其测量的RSRP值大于某个阈值
(1.2)跟***消息具有相同的polarization
(2)上行传输使用的polarization与接收下行用于估计pathloss的信号(SSB/CSI-RS)polarization相同。
在一些实施例中,允许发送端和接收端使用不同的polarization,并引入功率补偿或者定位信息度量补偿,该补偿可以取决于如下一种或者多种因素和方法:
(1)补偿(Compensation)由网络配置,可以是cell/UE/channel/signal specific的;
(2)预先确定;
(3)取决于不同场景,比如GEO和LEO case可以不同;
(4)取决于不同{发送(transport,TX)polarization,接收(receive,RX)polarization}组合;
比如,对于LEO场景,定义如下表3预先确定路径损耗(pathloss)补偿;
表3
注意上面的举例中,9dB的方格对应的情形也可以认为是UE不期望出现的情况,因为这时可能收不到任何信号,可以使用前面实施例的方法。
在一些实施例中,允许发送端和接收端使用不同的polarization,此时使用如下一种或者多种规则:
(1)使用预定义或者网络配置的的TX power
(2)使用预定义或者网络配置的pathloss
比如,这种情况下,终端直接使用UE允许的最大power PCmax发送。
示例二:指示polarization信息的***消息发送前的信号的极化确定
指示polarization信息的***消息发送前的信号这称为第一目标信号,可以是PRACH信号,或者其他早于携带polarization的OSI消息的信号。
在一些实施例中,在SIB1或者MIB中per SSB/CSI-RS的配置polarization,这样确保发送第一信号的polarization可以是与第一目标信号关联的SSB/CSI-RS的polarization相同。
在一些实施例中,在SIB1或者MIB中配置common的polarization,并且SSB/CSI-RS的polarization相同。
示例三:间接通过pathloss补偿极化损失
在一些实施例中,规定发送上行的polarization与接收用于测量path loss的下行信号所使用的polarization相同。
这样估计出来的pathloss在收发polarization不同的情况下会由于polarization loss而变大,从而间接使得极化loss在上行发送功率上得到补偿。
