Abstract
Description
本公开要求于2023年09月22日提交中国专利局、申请号为202311233514.7、申请名称为“一种信息处理方法、装置及设备”的中国专利申请的优先权,其全部内容通过引用结合在本公开中。This disclosure claims the priority of the Chinese patent application filed with the China Patent Office on September 22, 2023, with application number 202311233514.7 and application name “A method, device and apparatus for information processing”, the entire contents of which are incorporated by reference in this disclosure.
本公开涉及通信技术领域,尤其涉及一种信息处理方法、装置及设备。The present disclosure relates to the field of communication technology, and in particular to an information processing method, device and equipment.
针对非地面网络(Non-Terrestrial Network,NTN)场景,目前在讨论对用户设备(User Equipment,UE)的位置进行检验,以确保UE上报位置正确性、合理性,这样网络侧对UE提供的服务才能更好的满足当地法律及监管的需要。具体的,目前在讨论NTN场景下多径行程时间(Multi-Round Trip Time,Multi-RTT)方式的UE测量量:UE Rx(接收)-Tx(发送)时差的表达形式,主要倾向的方案是采用现有标准中新空口(New Radio,NR)的UE Rx-Tx时差参数+offset(偏移量)来表示NTN场景下的UE Rx-Tx时差。但是,并未讨论具体的往返时延(Round-Trip Time,RTT)的计算方式,而现有获取RTT的方案应用于NTN场景下得到的结果精度很差,因此并不适用于NTN场景。For non-terrestrial network (NTN) scenarios, the location of user equipment (UE) is currently under discussion to ensure the correctness and rationality of the location reported by the UE, so that the services provided by the network to the UE can better meet the needs of local laws and regulations. Specifically, the UE measurement quantity in the multi-path trip time (Multi-RTT) mode in the NTN scenario is currently under discussion: the expression of the UE Rx (receive)-Tx (send) time difference. The main preferred solution is to use the UE Rx-Tx time difference parameter + offset of the existing standard New Radio (NR) to represent the UE Rx-Tx time difference in the NTN scenario. However, the specific calculation method of the round-trip time (RTT) is not discussed, and the existing solution for obtaining RTT is applied to the NTN scenario. The result obtained is very poor in accuracy, so it is not suitable for the NTN scenario.
由上,相关技术中针对NTN场景获取的RTT的精度会很差。As described above, the accuracy of the RTT obtained for the NTN scenario in the related art will be very poor.

下面首先对本公开实施例提供的方案涉及的内容进行介绍。The following first introduces the contents involved in the solution provided by the embodiment of the present disclosure.
1)5G NR;1) 5G NR;
目前5G NR系统,采用Multi-RTT测量过程中,由于基站是静置的,因此不考虑定时变化对RTT的影响。In the current 5G NR system, when using Multi-RTT measurement, since the base station is stationary, the impact of timing changes on RTT is not considered.
2)NTN网络;2) NTN network;
针对NTN场景,特别是低轨卫星场景,由于卫星运动快,所以UE收到的信号会受多普勒的影响而导致子帧长度扩展或者收缩,因此该场景下需要考虑定时变化对RTT的影响;但是,针对业务链路(卫星到UE)下行timing drift(定时漂移或定时变化)对往返时延(Round-Trip Time,RTT)的影响,目前并未给出明确的RTT的计算方式。也就是,目前标准未考虑链路的定时变化对RTT的影响,所以目前的RTT获取方案无法适应NTN场景。For NTN scenarios, especially low-orbit satellite scenarios, due to the fast movement of satellites, the signal received by the UE will be affected by Doppler, resulting in the expansion or contraction of the subframe length. Therefore, in this scenario, the impact of timing changes on RTT needs to be considered; however, for the impact of the downlink timing drift (timing drift or timing change) of the service link (satellite to UE) on the round-trip time (RTT), there is currently no clear RTT calculation method. In other words, the current standard does not consider the impact of link timing changes on RTT, so the current RTT acquisition solution cannot adapt to the NTN scenario.
其中,业务链路:指卫星与UE间链路;馈电链路:指卫星与信关站间链路。Among them, the service link refers to the link between the satellite and the UE; the feeder link refers to the link between the satellite and the gateway.
目前在讨论UE location verification(UE位置验证)议题时,为了尽量沿用NR标准中UE Rx-Tx参数和gNB(the next Generation Node B,5G基站)Rx-Tx参数的定义方式,最终选择了用下述方式表征和计算UE到上行定时参考点UTSRP或gNB的RTT,具体下面以UTSRP为例介绍这种方式,如图2所示(图中DL表示下行,UL表示上行);根据上述UE Rx-Tx参数的表示方法,UE到UTSRP间的RTT如下式:At present, when discussing the topic of UE location verification, in order to follow the definition of UE Rx-Tx parameters and gNB (the next Generation Node B, 5G base station) Rx-Tx parameters in the NR standard as much as possible, the following method is finally chosen to characterize and calculate the RTT from UE to the uplink timing reference point UTSRP or gNB. Specifically, this method is introduced using UTSRP as an example, as shown in Figure 2 (DL represents downlink and UL represents uplink in the figure); according to the above-mentioned representation method of UE Rx-Tx parameters, the RTT between UE and UTSRP is as follows:
RTTUE-UTSRP=TUE-offset+(TUE-Rx-TUE-Tx)+(TgNB-Rx-TgNB-Tx)+ΔTA;RTT UE-UTSRP =T UE-offset +(T UE-Rx -T UE-Tx )+(T gNB-Rx -T gNB-Tx )+ΔTA;
其中,定时提前量(Timing Advance,△TA)为TA#l-TA#i的时间差。TUE-offset为终端的上行子帧#i到上行子帧#j的整数(子帧)间隔对应的时长,上行子帧#j是距离下行子帧#i(携带PRS)最近的上行子帧。TUE-Rx-TUE-Tx为目前标准中NR的UE Rx-Tx参数表示方法。TgNB-Rx-TgNB-Tx也是目前标准中NR的gNB Rx-Tx参数的表示方法,TgNB-Rx-TgNB-Tx对应图2中UTSRP DL与UTSRP UL之间的两条虚线之间的间隔。子帧l是携带SRS的子帧。TA#i=TUE-offset+(TUE-Rx-TUE-Tx)。Among them, the timing advance (Timing Advance, △TA) is the time difference of TA#l-TA#i. T UE-offset is the duration corresponding to the integer (subframe) interval from the uplink subframe #i to the uplink subframe #j of the terminal. The uplink subframe #j is the uplink subframe closest to the downlink subframe #i (carrying PRS). T UE-Rx -T UE-Tx is the UE Rx-Tx parameter representation method of NR in the current standard. T gNB-Rx -T gNB-Tx is also the gNB Rx-Tx parameter representation method of NR in the current standard. T gNB-Rx -T gNB-Tx corresponds to the interval between the two dotted lines between UTSRP DL and UTSRP UL in Figure 2. Subframe l is the subframe carrying SRS. TA#i=T UE-offset +(T UE-Rx -T UE-Tx ).

下面对本公开实施例提供的所述信息处理方法进行举例说明,网络设备以位置管理功能(Location Management Function,LMF)为例。The information processing method provided in the embodiment of the present disclosure is illustrated below by taking the location management function (LMF) of a network device as an example.
针对上述技术问题,本公开实施例提供了一种信息处理方法,具体可实现为一种含定时变化率的往返时延(Round-Trip Time,RTT)计算方法,具体的,是针对NTN场景下的Multi-RTT定位方法的RTT计算提出一种方案,涉及:将业务链路和馈电链路的定时变化因素均考虑在内(即考虑业务链路的定时变化和馈电链路的定时变化对RTT的影响),给出了RTT的计算方法,提高了RTT的精度。其中,本方案涉及网络侧行为和终端侧行为,具体可如下:In response to the above technical problems, the disclosed embodiment provides an information processing method, which can be implemented as a round-trip time (RTT) calculation method including a timing change rate. Specifically, a scheme is proposed for RTT calculation of the Multi-RTT positioning method in the NTN scenario, which involves: taking into account the timing change factors of the service link and the feeder link (i.e., considering the impact of the timing change of the service link and the timing change of the feeder link on the RTT), providing a method for calculating the RTT, and improving the accuracy of the RTT. Among them, this scheme involves network-side behavior and terminal-side behavior, which can be specifically as follows:
(1)网络侧行为,包括:(1) Network-side behavior, including:
1)位置管理功能(Location Management Function,LMF)从gNB(基站)接收有效的、未过期的TA common(即公共TA,表示UTSRP到卫星的RTT)、TAcommonDrift(即公共TA变化率,表示UTSRP到卫星的RTT的变化率)和TAcommonDriftVariation(即公共TA变化率的变化率,表示UTSRP到卫星的RTT的变化率的变化率)等参数;对应于上述接收基站发送的有效期内的TA变化率信息。1) The Location Management Function (LMF) receives valid, unexpired parameters such as TA common (i.e., public TA, indicating the RTT from UTSRP to the satellite), TA common Drift (i.e., public TA change rate, indicating the rate of change of the RTT from UTSRP to the satellite) and TA common Drift Variation (i.e., the rate of change of the public TA change rate, indicating the rate of change of the RTT from UTSRP to the satellite) from the gNB (base station); corresponding to the TA change rate information within the validity period sent by the above-mentioned receiving base station.
2)LMF从UE接收上行子帧#i到上行子帧#j的整数(子帧)间隔对应的时长TUE-offset、(TUE-Rx-TUE-xx)、TimingDriftRate等参数,对应于上述网络设备接收所述终端发送的所述整数子帧间隔对应的时长、所述终端接收发送时差以及业务链路的定时变化率;其中TimingDriftRate表示业务链路下行定时变化率(即业务链路的定时变化率);上行子帧#i与下行子帧#i(包含下行PRS(Positioning Reference Signal,定位参考信号))对应,上行子帧#j是离下行子帧#i最近的一个,上行子帧#i对应于上述第一上行子帧,上行子帧#j对应于上述第二上行子帧,下行子帧#i对应于上述第一下行子帧;其中,TUE-Rx-TUE-Tx表示UE Rx(接收)-Tx(发送)时差,对应于上述终端接收发送时差。2) The LMF receives the duration T UE-offset , (T UE-Rx -T UE-xx ), TimingDriftRate and other parameters corresponding to the integer (subframe) interval from the uplink subframe #i to the uplink subframe #j from the UE, which corresponds to the duration corresponding to the integer subframe interval sent by the terminal received by the above-mentioned network device, the terminal receiving and sending time difference and the timing change rate of the service link; wherein TimingDriftRate represents the downlink timing change rate of the service link (i.e., the timing change rate of the service link); the uplink subframe #i corresponds to the downlink subframe #i (including the downlink PRS (Positioning Reference Signal)), the uplink subframe #j is the one closest to the downlink subframe #i, the uplink subframe #i corresponds to the above-mentioned first uplink subframe, the uplink subframe #j corresponds to the above-mentioned second uplink subframe, and the downlink subframe #i corresponds to the above-mentioned first downlink subframe; wherein T UE-Rx -T UE-Tx represents the UE Rx (receive)-Tx (send) time difference, corresponding to the above-mentioned terminal receiving and sending time difference.
3)LMF根据接收的信息计算UE到UTSRP间的RTT:RTTUE-UTSRP;对应于上述根据所述整数子帧间隔对应的时长、所述终端接收发送时差、所述基站接收发送时差、所述定时提前量的变化量以及所述TA变化率信息,确定所述终端到UTSRP的RTT。 3) LMF calculates the RTT between UE and UTSRP based on the received information: RTT UE-UTSRP ; corresponding to the duration corresponding to the integer subframe interval, the terminal receiving and sending time difference, the base station receiving and sending time difference, the change in the timing advance and the TA change rate information, determines the RTT from the terminal to UTSRP.
(2)终端侧行为,包括:(2) Terminal-side behavior, including:
1)UE测量上行子帧#i与上行子帧#j间的间隔对应的时长TUE-offset,即整数倍的子帧数目对应的时长,其中,上行子帧#j是离下行子帧#i(包含下行PRS(Positioning Reference Signal,定位参考信号)信号)最近的一个。1) The UE measures the duration T UE-offset corresponding to the interval between uplink subframe #i and uplink subframe #j, i.e., the duration corresponding to an integer multiple of the number of subframes, where uplink subframe #j is the one closest to downlink subframe #i (including a downlink PRS (Positioning Reference Signal) signal).
2)UE测量下行子帧#i与上行子帧#j的时差,得到TUE-Rx-TUE-Tx。2) The UE measures the time difference between the downlink subframe #i and the uplink subframe #j to obtain T UE-Rx -T UE-Tx .

Among them, the uplink subframe #l (corresponding to the above-mentioned third uplink subframe) is the subframe in which the UE sends the SRS signal. The purpose of reporting is to enable the network side to obtain the interval (li) from the uplink subframe #i to the uplink subframe #l. This interval will be affected by the timing change rate and will affect the accuracy of the final measurement.
基于以上,本方案具体包括:Based on the above, this plan specifically includes:
(1)一种基于业务链路定时变化和馈电链路定时变化的RTT计算方法;(1) A RTT calculation method based on service link timing variation and feeder link timing variation;
(2)一种基于业务链路定时变化的UE Rx-Tx时差TUE-offset计算方法;(2) A method for calculating the UE Rx-Tx time difference T UE-offset based on the service link timing change;
(3)一种两个不同上行子帧的TA差额(对应于上述定时提前量的变化量)计算方法。(3) A method for calculating the TA difference (corresponding to the change in the timing advance) between two different uplink subframes.
下面对本方案进行具体举例说明。The following is a specific example to illustrate this solution.
1)计算TUE-offset的方法;1) Method for calculating T UE-offset ;
目前UE上报的是上行子帧#j索引和上行子帧#i索引间的差值,是整数倍的子帧个数,由于受到卫星运动的影响,子帧的长度发生变化,不再是1ms长,因此需要考虑定时变化率对该参数的影响,具体计算方法如下:Currently, the UE reports the difference between the uplink subframe #j index and the uplink subframe #i index, which is an integer multiple of the number of subframes. Due to the influence of satellite motion, the length of the subframe changes and is no longer 1ms long. Therefore, it is necessary to consider the impact of the timing change rate on this parameter. The specific calculation method is as follows:
TUE-offset=(1+TimingDriftRate)×n;T UE-offset = (1+TimingDriftRate)×n;
其中,n=j-i,为上行子帧#i与上行子帧#j之间的索引差额(对应于上述第一索引差值,也即整数子帧间隔);TimingDriftRate为业务链路的定时变化率。Among them, n=j-i, is the index difference between uplink subframe #i and uplink subframe #j (corresponding to the above-mentioned first index difference, that is, an integer subframe interval); TimingDriftRate is the timing change rate of the service link.
2)△TA(对应于上述定时提前量的变化量)的计算方法;2) Calculation method of ΔTA (corresponding to the change in the timing advance amount mentioned above);
△TA是指上行子帧#l的定时提前量与上行子帧#i的定时提前量间的差额,对应于上述定时提前量的变化量是指所述终端的第三上行子帧的定时提前量与所述第一上行子帧的定时提前量之间的差值。具体的:ΔTA refers to the difference between the timing advance of uplink subframe #1 and the timing advance of uplink subframe #i, and the change corresponding to the above timing advance refers to the difference between the timing advance of the third uplink subframe of the terminal and the timing advance of the first uplink subframe. Specifically:
△TA=TA#l-TA#i;△TA=TA#l-TA#i;
而TA#l和TA#i可以分别表示为:TA#l and TA#i can be expressed as:
TA#l=TA#lUE specific+TA#lcommon;TA#l=TA#l UE specific +TA#l common ;
TA#i=TA#iUE specific+TA#icommon;TA#i=TA#i UE specific +TA#i common ;
其中,TA#lUE specific表示业务链路的TA,TA#lcommon为馈电链路的TA。Among them, TA#l UE specific represents the TA of the service link, and TA#l common represents the TA of the feeder link.
基于以上,△TA可以表示为: Based on the above, △TA can be expressed as:
ΔTA=TA#l-TA#iΔTA=TA#l-TA#i
=(TA#lUE specific-TA#iUE specific)+(TA#lcommon-TA#icommon);=(TA#l UE specific -TA#i UE specific )+(TA#l common -TA#i common );
而其中:Among them:
TA#lUE specific-TA#iUE specific=TimingDriftRate×(l-i);TA#l UE specific -TA#i UE specific =TimingDriftRate×(li);
TA#lcommon-TA#icommon=TACommonDrift×(l-i)+TACommonDriftVariation×(l-i)2;TA#l common -TA#i common =TACommonDrift×(li)+TACommonDriftVariation×(li) 2 ;
综上可以得到:In summary, we can get:
ΔTA=(TimingDriftRate+TACommonDrift)×(l-i)+ΔTA=(TimingDriftRate+TACommonDrift)×(l-i)+
TACommonDriftVariation×(l-i)2;TACommonDriftVariation×(li) 2 ;
从上式可以看到△TA的取值与TimingDriftRate、TACommonDrift、TACommonDriftVariation以及上行子帧#l和上行子帧#i间的间隔有关;对应于上述根据所述定时变化率、所述第二索引差值、所述公共TA变化率以及所述公共TA变化率的变化率,得到所述定时提前量的变化量。From the above formula, it can be seen that the value of △TA is related to TimingDriftRate, TACommonDrift, TACommonDriftVariation and the interval between uplink subframe #l and uplink subframe #i; corresponding to the above-mentioned change rate of the timing change rate, the second index difference, the common TA change rate and the rate of change of the common TA change rate, the change amount of the timing advance is obtained.
3)RTTUE-UTSRP计算方式;3) RTT UE-UTSRP calculation method;
根据△TA和TUE-offset计算最终的RTT(即UE到UTSRP间的RTT),得到如下形式:RTTUE-UTSRP=(TUE-Rx-TUE-Tx)+(TgNB-Rx-TgNB-Tx)The final RTT (i.e., the RTT between UE and UTSRP) is calculated based on ΔTA and T UE-offset and is given as follows: RTT UE-UTSRP = (T UE-Rx - T UE-Tx ) + (T gNB-Rx - T gNB-Tx )
+(1+TimingDriftRate)×(j-i)+(1+TimingDriftRate)×(j-i)
+(TimingDriftRate+TACommonDrift)×(l-i)+(TimingDriftRate+TACommonDrift)×(l-i)
+TACommonDriftVariation×(l-i)2;+TACommonDriftVariation×(li) 2 ;
其中,TgNB-Rx-TgNB-Tx表示gNB Rx-Tx时差,对应于上述基站接收发送时差。Among them, TgNB -Rx - TgNB-Tx represents the gNB Rx-Tx time difference, which corresponds to the above-mentioned base station reception and transmission time difference.
由上,RTTUE-UTSRP的取值与业务链路定时变化、馈电链路定时变化(与“所述公共TA变化率以及所述公共TA变化率的变化率”对应)以及子帧索引间隔有关;对应于上述根据所述整数子帧间隔对应的时长、所述终端接收发送时差、所述基站接收发送时差、所述定时提前量的变化量、所述公共TA变化率以及所述公共TA变化率的变化率,确定所述终端到UTSRP的RTT。From the above, the value of RTT UE-UTSRP is related to the service link timing change, the feeder link timing change (corresponding to "the common TA change rate and the rate of change of the common TA change rate") and the subframe index interval; corresponding to the above-mentioned duration corresponding to the integer subframe interval, the terminal receiving and sending time difference, the base station receiving and sending time difference, the change in the timing advance, the common TA change rate and the rate of change of the common TA change rate, the RTT from the terminal to UTSRP is determined.
此外,上述计算RTT是针对涉及TAcommonDrift、TAcommonDriftVariation以及TimingDriftRate的举例,本方案中计算RTT也可以只涉及TimingDriftRate,或者涉及TimingDriftRate和TACommonDrift,具体比如:In addition, the above RTT calculation is an example involving TAcommonDrift, TAcommonDriftVariation and TimingDriftRate. In this solution, the RTT calculation may also only involve TimingDriftRate, or TimingDriftRate and TACommonDrift, for example:
(1)如果只涉及TimingDriftRate,可采用如下公式计算RTT:(1) If only TimingDriftRate is involved, the following formula can be used to calculate RTT:
RTTUE-UTSRP=(TUE-Rx-TUE-Tx)+(TgNB-Rx-TgNB-Tx)+(1+TimingDriftRate)×(j-i)+ΔTA;RTT UE-UTSRP = (T UE-Rx -T UE-Tx )+(T gNB-Rx -T gNB-Tx )+(1+TimingDriftRate)×(ji)+ΔTA;
或者,如下公式计算RTT:Alternatively, the RTT can be calculated using the following formula:
RTTUE-UTSRP=(TUE-Rx-TUE-Tx)+(TgNB-Rx-TgNB-Tx)+(1+TimingDriftRate)×(j-i)+(TimingDriftRate)×(l-i);RTT UE-UTSRP = (T UE-Rx -T UE-Tx )+(T gNB-Rx -T gNB-Tx )+(1+TimingDriftRate)×(ji)+(TimingDriftRate)×(li);
(2)如果涉及TimingDriftRate和TACommonDrift,可采用如下公式计算RTT: RTTUE-UTSRP=(TUE-Rx-TUE-Tx)+(TgNB-Rx-TgNB-Tx)(2) If TimingDriftRate and TACommonDrift are involved, the following formula can be used to calculate RTT: RTT UE-UTSRP = (T UE-Rx -T UE-Tx )+(T gNB-Rx -T gNB-Tx )
+(1+TimingDriftRate)×(j-i)+(1+TimingDriftRate)×(j-i)
+(TimingDriftRate+TACommonDrift)×(l-i);+(TimingDriftRate+TACommonDrift)×(l-i);
当然也可以只涉及其他参数信息,可参见以上举例进行操作,在此不再赘述。Of course, it is also possible to only involve other parameter information. Please refer to the above examples for operation, which will not be repeated here.
由上,本方案针对卫星运动对UE Rx-Tx测量量造成影响的问题,提出了解决方案:采用业务链路定时变化率对UE Rx-Tx测量量的TUE-offset进行计算修正,以及,采用业务链路和馈电链路的定时变化率对RTT进行计算,提高RTT的精度。From the above, this scheme proposes a solution to the problem of satellite movement affecting UE Rx-Tx measurement: using the service link timing change rate to calculate and correct the UE Rx-Tx measurement T UE-offset , and using the timing change rate of the service link and the feeder link to calculate the RTT to improve the accuracy of the RTT.
