  • Timing Advance UE-specific uplink timing advance
  • K_offset scheduling time slot offset
  • the UE updates the uplink TA to the base station, optionally in the following ways:
  • Method 1 By mapping TA or TA range to the preamble sending opportunity (RO): UE sends the preamble (Preamble) in the selected RO, and the base station can know the TA at the media access control (MAC) layer.
  • ROI preamble sending opportunity
  • Method 2 Through the radio resource control (RRC) message: UE fills the uplink TA to the defined high-layer RRC message, and transmits it to the base station through the uplink shared channel (PUSCH). After the upper layer of the base station analyzes it, it notifies the MAC layer of the base station to further calculate K_offset or TA command (command).
  • RRC radio resource control
  • Method 3 Through MAC CE (control element): define the MAC CE of the new UE to report the TA, carry it to the base station through the PUSCH, and the base station can know the TA at the MAC layer.
  • RA access resources need to be occupied, and because UE specific (proprietary) TA updates are relatively frequent, frequent triggering of RA access will consume UE power.
  • Mode 2 it should be placed in the high-level RRC layer and transmitted to the base station through PUSCH. After the high-level analysis of the base station, it will be passed to the MAC layer of the base station. ), it is necessary to send a scheduling request SR to the base station first, which will occupy additional uplink resources, and the additional steps will consume the power of the UE.
  • Mode 3 since the newly defined MAC CE is used, the base station can obtain the TA through the MAC CE, and perform further processing at the MAC layer. However, since it needs to be carried and transmitted to the base station through the PUSCH, as in mode 2, an uplink buffer is also required for transmission. If not, the SR needs to be sent to the base station first, and then transmitted to the base station through PUSCH, which will occupy additional uplink resources, and the extra steps will consume the power of the UE.

Description

一种信息传输方法、装置、终端及网络设备
相关申请的交叉引用
本公开主张在2021年06月03日在中国提交的中国专利申请号No.202110619664.6的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域,尤其涉及一种信息传输方法、装置、终端及网络设备。
背景技术
在第五代移动通信技术(5th Generation Mobile Communication Technology,5G)版本(Release)17非陆地网络系统(non-terrestrial networks,NTN)中,用户设备(User Equipment,UE)会根据全球导航卫星系统(Global Navigation Satellite System,GNSS)和星历计算UE专有上行定时提前(Timing Advance,TA),基站为了更好的控制UE上行传输和资源调度(包括计算调度时隙偏移(K_offset)),UE需要把TA上报给基站。
目前,UE更新上行TA到基站,可选地有以下几种方式:
方式1.通过映射TA或者TA范围到前导码发送时机(RO):UE通过在选定的RO发送前导码(Preamble),基站在媒体介入控制(MAC)层就可以获知TA。
方式2.通过无线资源控制(RRC)消息:UE填充上行TA到定义的高层RRC消息,通过上行共享信道(PUSCH)传给基站。基站高层解析后,通知基站MAC层,进一步计算K_offset或TA指令(command)。
方式3.通过MAC CE(控制元素):定义新的UE上报TA的MAC CE,通过PUSCH携带传给基站,基站在MAC层就可以获知TA。
但是,以上几种UE上报TA方式存在以下缺陷:
方式1,要通过RA接入(随机接入)来实现,需要占用RA接入资源,而且由于UE specific(专有)TA更新比较频繁,频繁的触发RA接入会消 耗UE的电力。
方式2,要放在高层RRC层通过PUSCH传输给基站,由基站高层解析后,再传递给基站MAC层,效率不如直接在MAC层解析,另外由于要通过PUSCH传输,如果当前没有上行Buffer(缓存),还要给基站先发送调度请求SR,会占用额外上行资源,且额外的步骤会耗费UE的电力。
方式3,由于使用了新定义的MAC CE,基站可以通过MAC CE来获取TA,在MAC层做进一步处理。但是由于需要通过PUSCH携带传输给基站,和方式2一样,也需要有上行Buffer才能传输。如果没有,需要给基站先发送SR,再通过PUSCH传输给基站,会占用额外上行资源,且额外的步骤会耗费UE的电力。
由上可知,相关技术中针对TA的信息传输方案存在耗电量大等问题。

图1示出本公开实施例可应用的一种无线通信系统的框图。无线通信系统包括终端和网络设备。
本公开实施例涉及的终端,可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备等。在不同的系统中,终端的名称可能也不相同,例如在5G系统中,终端可以称为用户设备(User Equipment,UE)。无线终端可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网(Core Network,CN) 进行通信,无线终端可以是移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,例如,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,它们与无线接入网交换语言和/或数据。例如,个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(Session Initiated Protocol,SIP)话机、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)等设备。无线终端也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户装置(user device),本公开实施例中并不限定。

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。
在陆地网络系统中,上行同步,通过定时提前(Timing advance)来实现,基站通过发送TA指令(command)媒体介入控制(MAC)控制元素(CE)给UE,来保证不同的UE的上行传输能同时到达基站。基站通过测量UE发送的上行上行共享信道(PUSCH)或者信道探测参考信号,即上行探测参考信号(SRS)来计算TA command,然后通过TA command MAC CE发送给UE,UE根据收到的TA来调整自己的上行传输时间,具体参见图2所示的UE上行对齐或者上行时间同步的过程(是通过定时提前来实现上行对齐或者上行时间同步的)。其中,如果多个UE同时向gNB传输,gNB可能不能同时收到他们的信号,由于UE离gNB不同的距离,并因而不同的传播时延。为了维护在gNB的时间对齐,UE对上行传输应用相对于下行接收信号的时间提前。终端未进行应用时间提前的情况下,终端1和终端2同时向基站传输,但终端2离基站近,所以基站先检测到终端2的信号;终端进行了应用时间提前的情况下,终端1应用时间提前,终端1比终端2提前向基站传输,这样基站可以同时检测到终端1和终端2的信号。
此外,在5G Release 17非陆地网络系统,由于卫星相对于UE位置在变化,即UE位置和卫星星历会发生变化,如果只依赖基站测量上行信号,发送TA Command MAC CE来进行上行对齐或者上行时间同步,频繁的发送MAC CE会增加下行负荷,所以UE会根据GNSS和星历计算UE专有上行定时提前(TA),自动更新上行传输时间。在NTN(非陆地网络系统),从网络到UE位置的传播时延变化非常快,对于600km的低轨卫星(Low Earth Orbit,LEO),最大时延变化为+/-40μs/sec。具体的,是UE相对基站位置的变化, 用时间来表示,因为无线电传播的速度是一定的,用时间就可以表示UE相对位置的变化,这里的变化主要是卫星的移动造成的。μs/sec就是每秒变动了多少微秒。这里40微秒,乘以无线电传播速率,就可以得到UE相对位置变化的大小。
由于UE会自主计算UE专有上行定时提前(TA),gNB必须获得UE上行定时提前更新,也就是在何时多大幅度UE自动调整了上行传输时间(即UE自行校准的上行定时提前的时间,比方说提前了10个微秒发送上行数据,多大幅度就是指这10个微秒)。否则,gNB基于上行信号测量的TA command可能不再合适。这种情况下,需要UE根据设置的门限,或者周期性的,更新TA到基站侧。
另外由于非陆地网络系统较长的传输时延,Release 17在K1和K2的基础上引入了K_offset,进一步扩大调度时延。考虑小区中心和小区边缘的传输时延不同,初始接入后的K_offset可以根据UE来进行更新,称为UE specific K_offset(UE专有K_offset)。基站可以通过TA来推导K_offset,这就需要UE要上报UE专有上行定时提前,以便基站推导合理的UE专有K_offset。其中,K1和K2是5G引入的时隙偏移参数,K1是UE收到PDCCH(下行控制信道),到UE发送确定应答(ACK)这段偏移时间,K2是UE收到PDCCH,到UE发送上行数据这段偏移时间。主要是用于更灵活的调度上下行数据。
基于以上,(在NTN(非陆地网络系统),从网络到UE位置的传播时延变化非常快,对于600km的LEO,最大时延变化为+/-40μs/sec),TA上报的周期可以计算如下:
1.对SCS为30k Hz;
2.相对TA最大更新时间是32×16×64×T c/2 u,u代表子载波间隔,u=0代表子载波间隔15kHz,u=1代表子载波间隔30kHz,依次类推;
3.T c是0.2543纳秒;
4.最大TA修正时间是32×16×64×0.2543/2=4微秒;
5.为了满足时延变化+/-40μs/sec,UE在一秒内进行80/4=20次TA更新;
6.TA更新周期为50ms。
通过上面的计算,可以知道TA更新周期已经接近信道质量指示(CQI) 40ms更新周期或者小于CQI 80ms更新周期,这样按照方式2或3单纯依赖PUSCH来进行TA上报,已经不是最优方案了。
关于时间参考点在gNB(基站)的上行对齐或上行时间同步可参见图3;其中,如图,t FL1是基站到卫星之间时延,t SL1是终端到卫星之间的时延,子帧0是系统时间起始子帧。从图中可以看出,基站在子帧0发送下行数据,经过t FL1到达卫星,又经过t SL1到达终端,终端根据下行同步信号检测解析下行数据。上行方向,UE需要提前t FL1+t SL1发送上行数据,这样可以保证基站在子帧0收到上行数据。时间参考点在基站的上行时间对齐机制和地面网络上行时间对齐的机制是一样的。
关于非连接态和连接态下,参考点在基站的非陆地系统(NTN),初始TA和TA的维护示意,可参见图4和图5(初始TA非连接态和TA的维护连接态示意图),具体的:
(1)对于在RRC空闲态(RRC_IDLE)和/或RRC非激活态(RRC_INACTIE)初始TA,如图4所示:
步骤0:UE确保GNSS准备好。
步骤1:基站通过广播消息广播星历表和公共的(Common)TA。具体可以是通过系统信息块(SIB)进行广播。
步骤2:UE根据星历表和GNSS计算UE-卫星往返时延(RTT)作为特定终端(UE-specific)TA。
具体的,UE通过星历表和GNSS获取的UE位置计算UE-卫星RTT作为UE-specific TA。
步骤3:UE应用时间提前(对应于上述定时提前)用于消息1发送。具体的就是UE预补偿UE-gNB RTT。
步骤4:基站测量收到的时间差。
具体的,基站测量消息接收和配置的随机接入时机的时间差。
步骤5:基站发送携带了基于消息1接收测量的12位定时提前命令(Time advance Command,TAC)的消息2。
具体的,向终端发送12位在随机接入响应的定时提前命令(TAC RAR)。RAR表示随机接入响应(Randome Access Response)。
步骤6:UE基于收到的12位TAC调整定时提前。也就是,TA adjustment。
步骤7:UE应用调整的定时提前来发送消息3。同时,如果消息3有足够的负荷空间,UE上报计算的UE计算的定时提前(UE-calculated TA),如果没有,UE通过消息5或其他消息3后的上行调度授权(UL Grant)上报UE-calculated TA。
具体的,UE通过消息3发送UE-calculated TA报告(report)。
步骤8:收到TA上报后,基站获知绝对TA。向UE返回消息4。
具体的,基站根据绝对TA计算K_offset来调度发送消息4。
(2)对于在RRC连接态(RRC_Connected)TA的维护,如图5所示:
步骤9.UE保持GNSS或锁定GNSS。
具体的,UE通过跟踪或锁定GNSS来维护GNSS。
步骤10.基站通过广播消息广播星历表和Common TA。具体可以是通过系统信息块SIB进行广播。
步骤11.UE根据星历表和GNSS计算UE-卫星往返时延(RTT)作为UE-specific TA。
具体的,UE基于收到的GNSS获取的UE位置、星历表和Common TA,更新TA。
步骤12.UE通过PUSCH和/或PUCCH,更新UE-gNB RTT。
具体的,UE应用更新的TA来进行上行传输。
步骤13.基站测量上行传输的时间差。
也就是,基站测量收到的时间差。
步骤14.基站发送携带了基于测量的6位TAC的MAC-CE的PDSCH。
步骤15.UE根据收到的6位TAC来调整TA。也就是,TA adjustment。
步骤16.UE更新定时提前。
具体的,UE根据星历表和GNSS更新UE-specific TA。
步骤17.UE上报UE-calculated TA。
具体的,UE应用更新的TA并通过PUSCH上报UE-calculated TA。
步骤18.收到TA上报后,基站获知绝对TA。
从图4和图5可以看到,在这里UE向基站上报或更新TA是通过PUSCH 来实现的。
关于非陆地系统(NTN)K_offset概念可参见图6;从图中可以看到,和陆地系统相比,非陆地系统传播时延较长,可以通过在NR原有的K1和K2的基础上引入K_offset,来补偿非陆地系统传播时延。这样基站下发PDCCH到收到UE发来的混合自动重传请求(HARQ-ACK)反馈,时间长度是K1+K_offset。基站下发UL Grant到基站收到UE发送的PUSCH,时间长度是K2+K_offset。
在此说明,上行定时提前或者定时提前是指用于上行对齐(或上行时间同步)的时间提前量。

这样可以复用相关PUCCH和PUSCH资源,避免额外增加PUSCH空口 资源调度。
关于利用PUCCH发送TA信息,可以是在没有上行缓存(UL Buffer)的时候;关于利用PUSCH发送TA信息,可以是在有UL Buffer的时候;在此不作限定。
本公开实施例中,所述TA信息包括:TA类型信息、TA组标识以及TA索引值;其中,所述TA类型信息指示TA为相对TA或者绝对TA。
这样能够更加准确的传输TA信息。
其中,所述TA信息的传输优先级低于波速管理信息和RI的传输优先级,且高于除所述波速管理信息和RI外的其他CSI信息的传输优先级。
这样可以在信息传输有冲突时能按照优先级得到调度,正常的完成各信息的传输。
本公开实施例中,所述向网络设备发送携带定时提前TA信息的上行控制信息UCI,包括:在本次待传输的第一TA信息属于周期性传输信息或半持续传输信息,且上次传输的第二TA信息属于周期性传输信息或半持续传输信息(具体可以是携带于周期性CSI或半持续CSI中)的情况下,向网络设备发送携带所述第一TA信息的UCI;或者,在本次待传输的第一TA信息属于周期性传输信息或半持续传输信息,上次传输的第二TA信息属于非周期性传输信息(具体可以是携带于非周期性CSI中),且所述第一TA信息与第二TA信息之间的差值大于或等于门限值的情况下,向网络设备发送携带所述第一TA信息的UCI。

其中,采用π/2-BPSK能够进一步降低峰值平均功率比(PAPR),提高传输性能。
本公开实施例还提供了一种信息传输方法,应用于网络设备,如图8所示,包括:

其中,采用π/2-BPSK能够进一步降低PAPR(峰值平均功率比),提高传输性能。
本公开实施例中,具体使用Time Advance的时候可以是Time Alignment(时间对齐),在此不作限定。
下面对本公开实施例提供的所述信息传输方法进行举例说明。
针对上述技术问题,本公开实施例提供了一种信息传输方法,具体可实现为一种基于UCI(上行控制信息)的UE上报定时提前(TA)的方法,涉及 以下内容:
本公开中,UE更新TA到基站,可用于:
1.基站根据更新的TA,结合测量的上行信号,计算TA Command;
2.基站根据更新的TA,推导UE specific K_offset,用于上下行调度。
据此,可以认为UE更新TA是一种新的上行控制信息(Uplink Control Information,UCI)。本公开通过定义新的信道状态信息CSI反馈量(Report Quantity)来支持UE TA上报。这样UE TA可以通过CSI,周期性的或者半持续通过PUCCH上报给基站,也可以非周期的通过PUSCH上报给基站。这样复用了CSI上报机制,既可以和相关的CSI反馈量一起复用上报,也可以单独配置上报资源来单独上报。在有UL Buffer的时候,可以通过非周期CSI通过PUSCH上报给基站。在没有UL Buffer的时候,可以通过周期或半持续CSI通过PUCCH上报给基站。这样避免了占用额外PUSCH和RA资源,充分利用相关CSI资源。对相关协议修改较小,只需要增加新的CSI反馈量(在CSI中增加TA)和TA负荷格式,其他都可以复用相关协议。本方案具体涉及:
1.CSI反馈量;
可以在报告配置(CSI-ReportConfig)中的报告质量(Report Quantity)中,增加TA;对于单TA的CSI反馈量,可以不配置相关测量资源设置(这个是针对CSI上报的区别,当CSI作为UCI上报的时候,CSI需要测量基站配置的CSI-RS参考信号,根据测量结果来上报。对于TA来说,不需要给UE配置专门的测量参考信号,UE通过测量下行信号,可以获得TA,然后自行调整)。
具体的,可以在上行状态信息上报配置中,增加新的反馈量,来支持上行定时提前的上行控制信息上报。增加的反馈量可如下:
上行状态信息参考信号资源指示-秩指示-预编码矩阵指示-信道质量状态指示-上行定时提前cri-RI-PMI-CQI-TA;
上行状态信息参考信号资源指示-秩指示-第一级码本-上行定时提前cri-RI-i1-TA;
上行状态信息参考信号资源指示-秩指示-层指示-预编码矩阵指示-信道 质量状态指示-上行定时提前cri-RI-LI-PMI-CQI-TA;
上行定时提前TA。
2.UE上报TA格式,分两种情况,支持长格式TA和不支持长格式TA;
A.在初始接入过程中,UE需要上报完整(Full)TA给基站,这种情况下需要支持长格式TA。在RRC连接(Connected)状态下,UE可以更新相对TA给基站。A/R指示(即TA类型指示,对应于上述TA类型信息)是绝对TA还是相对TA上报,可以是:A/R为1时为绝对TA,A/R为0时为相对TA。TA组(TAG)标识(ID)为TAG的ID。TA Command为T A(即TA)索引值,相对TA可以是6位,绝对TA可以是12位,根据该指示确定TA的方式参见相关方案。这里可以看到TA最多给CSI反馈增加13bits负荷,考虑PUCCH format 3或4的容量,是可以满足要求的。示例如图9和图10所示,其中的
R bit可以为其他负荷或无负荷,Oct表示字节。A/R是绝对或相对TA标识符,A/R为1时,代表上报的是绝对TA,用于初始接入时UE上报绝对TA。A/R为0时,代表上报的是相对TA,UE在连接态下,上报相对TA给基站。TA command是定时提前命令,包含TA值,绝对TA是12位,相对TA是6位。TAG ID是TA Group ID,TA组的标识,不同的TA组维护各自的TA。
B.如果不考虑长格式TA(绝对TA),可以只支持相对TA,示例如图11所示,其中的Oct表示字节。
3.CSI优先级;
考虑到UE上报的TA要用来推导UE specific K_offset,用于上下行调度或者用于计算TA Command,当UE同时上报秩指示(RI)、上行状态信息参考信号资源指示CRI和信道质量状态指示CQI、上行定时提前TA或波束管理的CSI的请求资源冲突时,优先级从高到低为波速管理>RI>TA>CRI和CQI(对应于即除波速管理和RI外的其他CSI),该优先级对应于上述所述TA信息的传输优先级低于波速管理信息和RI的传输优先级,且高于除所述波速管理信息和RI外的其他CSI信息的传输优先级。
4.对于同时配置了周期和/或半持续TA上报以及非周期TA上报的场景, 可以通过RRC层配置门限参数,在准备周期TA上报时,如果准备上报的TA值和最近一次非周期TA的差值小于门限,UE可以不进行周期TA上报(这是针对最近一次TA上报是非周期TA的情况,否则,如果最近一次TA上报是周期TA,必须上报本次周期TA;对应于上述在本次待传输的第一TA信息属于周期性传输信息或半持续传输信息,且上次传输的第二TA信息属于周期性传输信息或半持续传输信息的情况下,向网络设备发送携带所述第一TA信息的UCI;在本次待传输的第一TA信息属于周期性传输信息或半持续传输信息,上次传输的第二TA信息属于非周期性传输信息,且所述第一TA信息与第二TA信息之间的差值大于或等于门限值的情况下,向网络设备发送携带所述第一TA信息的UCI;在本次待传输的第一TA信息属于周期性传输信息或半持续传输信息,上次传输的第二TA信息属于非周期性传输信息,且所述第一TA信息与第二TA信息之间的差值小于门限值的情况下,不执行向网络设备发送携带所述第一TA信息的UCI的操作)。
基站在接收周期TA时,如果没有检测到数据,认为TA不变(对应于上述在属于周期性传输信息的TA信息的当前传输时刻,未接收到所述TA信息的情况下,确定当前传输时刻的TA信息与上一传输时刻的TA信息相同)。这样可以进一步节省空口资源。下面是一个门限值定义示例:
上行定时提前上报门限值thresholdTA:整数INTEGER(1…64)。
5.调制和编码方式;
TA作为UCI可以通过PUCCH格式(format)2、3或4传输,通过QPSK或π/2-BPSK调制;此外,当TA(无除TA外的其他UCI,即不包含所述其他UCI)的负荷小于或等于11bits(上述第一比特的具体实现示例)时使用雷德-穆勒(Reed-Muller)码编码,当TA(无所述其他UCI)负荷大于11bits时使用极化(Polar)码编码。
下面对本方案进行具体举例,如图12所示:
假设一个UE上报TA,TA上报周期是10ms,门限是5,非周期TA每大于5ms有PUSCH调度时上报TA。从图中可以看到,在有UL Buffer时,可以通过PUSCH携带TA上报,在没有UL Buffer时,可以通过周期CSI在上行控制信道(PUCCH)上上报TA。与相关方法比,具有省电、节省PUSCH 资源(避免额外单独调用PUSCH来传输TA信息)、在MAC层处理,对相关协议修改较小等优点。
由上可知,本公开实施例提供的方案涉及:
1.一种基于UCI的通过PUCCH或PUSCH保证UE及时上报定时提前(TA)的方法。
2.基于1,通过配置CSI反馈量增加新的类型来支持TA在CSI里上报,可以复用相关CSI上报机制,最大化复用相关协议。
3.基于2,定义了UE通过CSI上报TA的格式,从而支持TA在PUCCH和PUSCH上上报,复用相关PUCCH和PUSCH资源,避免额外增加PUSCH空口资源调度。
4.基于3,定义了新的TA上报在CSI上报的优先级,保证TA上报资源和其他CSI上报资源冲突时,能按照优先级得到调度。
5.基于4,定义了UE上报TA的门限值,通过比较当前准备发送的TA和最近的非周期TA上报的差值,小于门限值时,可以取消周期性TA上报,进一步节省PUCCH资源。
综上,本方案与相关方法比,具有省电(与上述方式1通过PRACH相比省电;与上述方式2和3相比,在没有UL Buffer场景下,方式2和3完成一次TA传输要先发SR再由基站调度UE发送PUSCH,在这种场景下,本方案相比也省电),复用相关PUCCH和PUSCH资源,节省PUSCH资源(避免额外单独调用PUSCH来传输TA信息),在MAC层处理,对相关协议修改较小等优点。
