本申请实施例涉及移动通信技术领域,具体涉及一种上行传输方法及装置、终端设备、网络设备。
背景技术
通信系统场景包括地面通信网络(Terrestrial Network,TN)和非地面通信网络(Non Terrestrial Network,NTN)。其中,NTN一般采用卫星通信的方式向地面的终端设备提供通信服务。
NTN中,由于较大的信号传播时延和卫星移动等NTN网络的特性,再加上终端设备的发射功率不足,会产生终端设备的上行覆盖较弱的问题。在TN中可以基于DMRS绑定的联合信道估计来进行覆盖增强,然而,如何在NTN网络中应用该覆盖增强技术,目前并没有明确的方法。
发明内容

第五方面,本申请实施例提供一种终端设备,包括处理器和存储器。该存储器用于存储计算机程序,该处理器用于调用并运行该存储器中存储的计算机程序,执行上述第一方面所述的上行传输方法。
第六方面,本申请实施例提供的网络设备,包括处理器和存储器。该存储器用于存储计算机程序,该处理器用于调用并运行该存储器中存储的计算机程序,执行上述第二方面所述的上行传输方法。

3GPP正在研究非地面通信网络设备(Non Terrestrial Network,NTN)技术,NTN一般采用卫星通信的方式向地面用户提供通信服务。相比地面蜂窝网通信,卫星通信具有很多独特的优点。首先,卫星通信不受用户地域的限制,例如一般的陆地通信不能覆盖海洋、高山、沙漠等无法搭设通信设备或由于人口稀少而不做通信覆盖的区域,而对于卫星通信来说,由于一颗卫星即可以覆盖较大的地面,加之卫星可以围绕地球做轨道运动,因此理论上地球上每一个角落都可以被卫星通信覆盖。其次,卫星通信有较大的社会价值。卫星通信在边远山区、贫穷落后的国家或地区都可以以较低的成本覆盖到,从而使这些地区的人们享受到先进的语音通信和移动互联网技术,有利于缩小与发达地区的数字鸿沟,促进这些地区的发展。再次,卫星通信距离远,且通信距离增大通讯的成本 没有明显增加;最后,卫星通信的稳定性高,不受自然灾害的限制。
NTN技术可以和各种通信系统结合。例如,NTN技术可以和NR系统结合为NR-NTN系统。又例如,NTN技术可以和IoT系统结合为IoT-NTN系统。作为示例,IoT-NTN系统可以包括NB-IoT-NTN系统和eMTC-NTN系统。

作为示例,LEO卫星的高度范围可以为500千米~1500千米,相应轨道周期约可以为1.5小时~2小时,用户间单跳通信的信号传播延迟一般可小于20毫秒,最大卫星可视时间可以为20分钟,LEO卫星的信号传播距离短且链路损耗少,对用户终端的发射功率要求不高。GEO卫星的轨道高度可以35786km,围绕地球旋转周期可以为24小时,用户间单跳通信的信号传播延迟一般可为250毫秒。
为了保证卫星的覆盖以及提升整个卫星通信系统的系统容量,卫星采用多波束覆盖地面,一颗卫星可以形成几十甚至数百个波束来覆盖地面;一个卫星波束可以覆盖直径几十至上百公里的地面区域。
需要说明的是,图1至图3只是以示例的形式示意本申请所适用的系统,当然,本申请实施例所示的方法还可以适用于其它系统。此外,本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。还应理解,在本申请的实施例中提到的“指示”可以是直接指示,也可以是间接指示,还可以是表示具有关联关系。举例说明,A指示B,可以表示A直接指示B,例如B可以通过A获取;也可以表示A间接指示B,例如A指示C,B可以通过C获取;还可以表示A和B之间具有关联关系。还应理解,在本申请的实施例中提到的“对应”可表示两者之间具有直接对应或间接对应的关系,也可以表示两者之间具有关联关系,也可以是指示与被指示、配置与被配置等关系。还应理解,在本申请的实施例中提到的“预定义”、“协议约定”、“预先确定”或“预定义规则”可以通过在设备(例如,包括终端设备和网络设备)中预先保存相应的代码、表格或其他可用于指示相关信息的方式来实现,本申请对于其具体的实现方式不做限定。比如预定义可以是指协议中定义的。还应理解,本申请实施例中,所述“协议”可以指通信领域的标准协议,例如可以包括LTE协议、NR协议以及应用于未来的通信系统中的相关协议,本申请对此不做限定。
为便于理解本申请实施例的技术方案,以下对本申请实施例的相关技术进行说明,以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。
1、NTN系统中的同步技术:在NTN系统中,网络设备需要向终端设备发送同步辅助信息,该同步辅助信息用于终端设备完成时域同步和/或频域同步。同步辅助信息可以包括以下中的至少一项:服务卫星星历信息、公共定时提前(Timing Advance,TA)参数、参考时刻指示信息(epoch time, 用于确定t0时刻)、目标定时器的持续时间。
可选地,终端设备可以根据同步辅助信息和自身的全球导航卫星系统(Global Navigation Satellite System,GNSS)能力来完成相应的时域同步和/或频域同步。例如,终端设备可以基于其GNSS能力获得以下信息中的至少一个:终端设备的位置、时间基准和频率基准。接着,基于上述信息和同步辅助信息,终端设备可以获取定时和/或频偏,并在各个不同的状态(空闲态或非激活态或连接态)应用定时提前补偿和/或频偏调整。
可选地,终端设备可以根据以下公式(1)计算T TA值,并根据确定的T TA值确定上行信道或上行信号传输的定时:
T TA=(N TA+N TA,offset+N TA,adj common+N TA,adj UE)*Tc    (1)
其中,若上行信道包括PRACH或MsgA传输,则N TA取值为0,否则N TA是网络设备指示的TA值;N TA,offset根据布网频段和LTE或NR共存情况确定。N TA,adj common是根据高层配置的公共定时参数(例如公共定时值、公共定时值偏移值和公共定时值偏移值的变化率)得到的,如果高层未配置公共TA参数,则N TA,adj common取值为0。N TA,adj UE是终端设备根据其位置和高层配置的服务卫星星历信息计算得到的,如果高层未配置服务卫星星历信息,则N TA,adj UE取值为0。Tc表示采样时间间隔单位,Tc=1/(480*1000*4096)。
可选地,由于同步辅助信息会随着时间的变化而变化,因此,在NTN系统中需要为终端设备配置一个或多个定时器,该一个或多个定时器可以用于终端设备确定获取的同步辅助信息是否有效。例如,同步辅助信息可以对应一个目标定时器。当终端设备启动或重启该目标定时器后,在该目标定时器过期前(或者说目标定时器的持续时间结束前),终端设备可以假设其获取的同步辅助信息有效。
实际应用中,同步辅助信息中的服务卫星星历信息用于确定服务卫星的位置和速度状态(Position and Velocity State,PVS)向量信息。同步辅助信息中的服务卫星星历信息可以包括以下两种格式中的至少一种:
格式1:基于瞬时状态向量的星历信息格式,例如卫星在特定时刻的PVS向量。在该方式中,卫星星历信息包括t0时刻的基于地心坐标系的PVS向量(S X,S Y,S Z,V X,V Y,V Z)。
作为示例而非限定,终端设备根据卫星在t0时刻的基于地心坐标系的PVS向量,得到卫星在t时刻的基于地心坐标系的PVS向量。
格式2:基于轨道信息的星历信息格式。在该方式中,卫星星历信息包括t0时刻的星历参数(α(km),e,I(deg),Ω(deg),ω(deg),M(deg))。其中,α表示长半径(Semi-major,单位可以是米),e表示离心率(Eccentricity),ω表示近心点角(Argument of periapsis,单位可以是rad(弧度角)),Ω表示升交点经度(Longitude of ascending node,单位可以是rad),i表示倾斜度(Inclination,单位可以是rad),M表示参考时刻t0的平均近点角(Mean anomaly M at epoch time t0,单位可以是rad)。
作为示例而非限定,终端设备根据收到的t0时刻的该星历参数,可以得到卫星在t0时刻的基于地心地固(Earth-Centered,Earth-Fixed,ECEF)坐标系(也称为地心坐标系)的PVS向量。终端设备根据卫星在t0时刻的基于地心坐标系的PVS向量,可以得到卫星在t时刻的基于地心坐标系的PVS向量。
作为示例而非限定,终端设备根据收到的卫星在t0时刻的该星历参数,得到卫星在t时刻的星历参数;然后终端设备可以根据卫星在t时刻的该星历参数,得到卫星在t时刻的基于地心坐标系的PVS向量。
基于地心坐标系的PVS向量包括(S X,S Y,S Z,V X,V Y,V Z)。其中,(S X,S Y,S Z)对应卫星位置,单位是m;(V X,V Y,V Z)对应卫星速度,单位是m/s。
在上述两种格式中,格式2的通知方式相对于格式1来说,开销更小一些。但是在格式2中终端设备需要建模估计卫星的PVS向量,因此精度相对于格式1来说更差一些。
在本申请的一些实施例中,公共定时提前TA参数包括以下信息中的至少一项:公共定时值(单位是μs)、公共定时值偏移值(例如公共定时值的一阶导数,单位是μs/s)、公共定时值偏移值的变化率(例如公共定时值的二阶导数,单位是μs/s 2)。
NR系统中的覆盖增强技术:NR系统中,引入了基于解调参考信号(DeModulation Reference Signal,DMRS)绑定的联合信道估计的覆盖增强技术。该覆盖增强技术可以应用的目标上行信道包括物理上行共享信道(Physical Uplink Shared Channel,PUSCH)重复传输类型A(可以是DCI格式 0_1或DCI格式0_2调度的或预配置的),PUSCH重复传输类型B,一个TB在多个时隙上映射的PUSCH处理(TB processing over multiple slots,TBoMS)和物理上行控制信道(Physical Uplink Control Channel,PUCCH)重复传输。为了实现基于DMRS绑定的联合信道估计,需要对功率一致性及相位连续性、特殊时隙中的DMRS、采用时隙捆绑的时隙间跳频的时域跳频间隔等方面进行增强。
联合信道估计引入了名义时域窗口(Nominal time domain window,NTDW)和实际时域窗口(Actual time domain window,ATDW)的概念。一次目标上行信道的传输可以被一个或多个名义时域窗口覆盖,其中,除最后一个名义时域窗口外,其他名义时域窗口的长度可以是网络设备配置的或预定义的。一个名义时域窗口中可以包括一个或多个实际时域窗口。终端设备需要在一个实际时域窗口内保持功率一致性和相位连续性。对应地,网络设备可以在一个实际时域窗口内进行DMRS联合信道估计。
示例性的,在一个名义时域窗口(简称为名义TDW)中,第一个实际时域窗口(简称为实际TDW)的起始位置是该名义TDW中的第一个PUSCH的第一个符号,如果发生了破坏功率一致性和相位连续性的事件,则实际TDW的结束位置是事件发生前PUSCH传输的最后一个符号;否则,实际TDW的结束位置是该名义TDW中的最后一个PUSCH的最后一个符号。当破坏功率一致性和相位连续性的事件发生时,如果终端设备具有重启DMRS绑定的能力,则在事件结束后会创建一个新的实际TDW;如果终端设备不具有重启DMRS绑定的能力,则直到该名义TDW结束也不会创建新的实际TDW。其中,当终端设备支持DMRS绑定时,如果是由于半静态事件破坏功率一致性和相位连续性(例如事件不是由DCI或者MAC-CE触发的),则终端设备必须支持重启DMRS绑定;如果是由于动态事件破坏功率一致性和相位连续性(例如事件是由DCI或者MAC-CE触发的),终端设备是否支持重启DMRS绑定是一种可选的能力。
其中,破坏功率一致性和相位连续性的事件包括如下至少一项:
1、在时分双工(Time Division Duplex,TDD)频谱中,基于半静态下行/上行配置图案确定的下行时隙或者下行接收或者下行监听;
2、对于常规循环前缀(Cyclic Prefix,CP),两个连续上行信道传输之间的间隔大于13个符号;对于扩展CP,两个连续上行信道传输之间的间隔大于11个符号;
3、两个连续上行信道传输之间的间隔没有大于13个符号但在该间隔中被调度了其他的上行传输(或者说,对于多个连续时隙上的non-back-to-back PUSCH/PUCCH传输,两个PUSCH/PUCCH传输之间的其他上行传输);
4、基于协议定义的碰撞规则,丢弃或取消了上行信道传输;
5、两个连续PUSCH传输关联不同的UL波束(或者说,对于multi-TRP操作,如果同时配置了DMRS绑定和UL波束切换,对于multi-TRP操作,UL波束切换是一个破坏功率一致性和相位连续性的事件,该事件被当做一个半静态事件);
6、两个连续PUCCH传输关联不同的UL波束或不同的功控参数(或者说,对于multi-TRP操作,功控参数改变也是一个破坏功率一致性和相位连续性的事件,该事件被当做一个半静态事件);
7、当收到网络设备发送的TA命令后的上行TA调整;
8、频域跳频处理;
9、对于频分半双工紧凑型终端设备(reduced capability half-duplex UE,RedCap HD-FDD UE),基于协议定义的舍弃规则发生的PUSCH传输的丢弃或取消;和/或两个连续的PUSCH传输之间存在与下行接收/监听重叠的符号(即使两个重复传输的符号均没有与下行接收/监听重叠)。
目前NTN系统中,由于卫星移动等NTN网络的特性,信息传输存在较大的时延,因此可能会导致终端设备的覆盖较弱。在演进的NTN网络中,需要考虑终端设备的覆盖增强技术。例如,可以在NTN网络中引入基于DMRS绑定的联合信道估计的覆盖增强技术,然而,如何在NTN系统中应用该覆盖增强技术,目前并不清楚。
应理解,基于DMRS绑定的联合信道估计的覆盖增强技术需要终端设备支持上行重复传输,引入上行重复传输会导致终端设备的目标上行信道的传输时间持续较长,由于NTN系统中卫星时刻处于移动状态,如果终端设备在该目标上行信道传输过程中不进行时域和/或频域的同步调整,那么可能导致终端设备的上行同步不满足精度要求。然而,基于DMRS绑定的联合信道估计的增强覆盖技术,需要终端设备在一段时间内保持功率一致性和相位连续性。若终端设备在该目标上行信道传输过程中自行频繁进行时域和/或频域的同步调整,那么可能导致网络设备不能确定终端设备调整上行同步的时机,从而导致基于DMRS绑定的联合信道估计的增益降低。因此,在NTN系统中,如何在满足同步精度要求的情况下保证联合信道估计的增益,是亟待解决的问题。
为了解决该问题,本申请实施例提供一种上行传输方法。参考图4所示的流程示意图,本申请实施例提供的上行传输方法可以包括以下步骤:
步骤410、终端设备根据第一分段长度确定目标上行信道对应的分段时域窗口(Segment time domain window,STDW,简称为分段TDW),其中,目标上行信道包括N个上行信道,N为正整数;分段TDW与终端设备进行时域同步和/或频域同步调整的时间间隔具有关联关系;
步骤420、终端设备根据分段TDW发送目标上行信道。
步骤430、网络设备接收目标上行信道,目标上行信道在分段TDW中传输,所述分段TDW根据第一分段长度确定,所述分段TDW与所述终端设备进行时域同步和/或频域同步调整的时间间隔具有关联关系。
需要说明的是,所述终端设备可以是NTN中的终端设备,对应的网络设备为NTN中的网络设备。在一些实施例中,所述终端设备也可以是TN中的终端设备,对应的网络设备为TN中的网络设备,本申请实施例对此不做限制。
本申请实施例中,第一分段长度可以是时间长度或时域资源的长度。其中,第一分段长度的时间单元可以是一个/多个时隙、或者一个/多个子帧、或者一个/多个符号、或者一个/多个PUSCH的传输持续时间、或者一个/多个PUCCH的传输持续时间、或者一个/多个毫秒、或者一个/多个微秒等,本申请实施例对此不作限制。
需要说明的是,所述第一分段长度是预定义的,或者是根据预定义规则确定的,或者是根据网络设备发送的第一配置信息确定的,或者是根据网络设备配置的分段长度集合确定的,本申请实施例对此不做限制。
可选地,第一配置信息可以通过以下信息中的至少一种携带:
系统消息、无线资源控制(Radio Resource Control,RRC)信令、媒体接入控制(Medium Access Control,MAC)单元(Control Element,CE)、下行控制信息(Downlink Control Information,DCI)。
可选地,在所述终端设备处于连接态的情况下,所述第一配置信息通过终端设备专属RRC信令(例如RRC连接配置消息或RRC连接重配置消息)携带;和/或,在所述终端设备处于空闲态或非激活态的情况下,所述第一配置信息通过系统消息携带。
可选地,当被终端设备专属RRC信令配置所述第一配置信息时,终端设备根据所述终端设备专属RRC信令中的第一配置信息确定第一分段长度;否则,终端设备根据系统消息中的第一配置信息确定第一分段长度。
可选地,终端设备还可以根据预定义参数或预定义规则确定所述第一分段长度。
也就是说,终端设备可以自己计算第一分段长度。其中,预定义参数可以是终端设备的属性参数,或者能力参数等,本申请实施例对此不做限制。示例性的,预定义参数可以包括所述终端设备能够进行时域同步和/或频域同步的最小时间间隔;和/或,所述终端设备能够进行时域同步和/或频域同步的最大时间间隔。
预定义规则可以是终端设备与网络设备约定的规则,或者协议中定义的规则,本申请实施例对此不做限制。示例性的,预定义规则可以是将所述终端设备能够进行时域同步和/或频域同步的最大时间间隔作为所述第一分段长度,或者将所述终端设备进行时域同步和/或频域同步的最小时间间隔作为所述第一分段长度。
另外,本申请实施例中的目标上行信道中可以包括N个上行信道,N为大于或等于1的整数。可选地,该目标上行信道可以是通过时域资源分配指示确定的,例如,网络设备可以向终端设备发送时域资源分配指示,终端设备根据该时域资源分配指示确定目标上行信道。
需要说明的是,该时域资源分配指示可以是半静态的资源配置指示(例如通过RRC信令配置的PUSCH配置授权),也可以是动态资源分配指示(例如通过DCI的上行授权),本申请实施例对此不做限制。
可选地,目标上行信道可以包括以下中的至少一种:PUSCH,PUCCH和PRACH。
可选地,所述PUSCH包括N个上行信道(例如目标PUSCH包括N个PUSCH)时,该N个上行信道可以包括以下至少一种:PUSCH重复传输类型A,PUSCH重复传输类型B,以及一个TB在多个时隙上映射的PUSCH(TB processing over multiple slots,TBoMS)。
其中,PUSCH重复传输类型A可以是预配置的,或者通过DCI格式0_1或DCI格式0_2调度,本申请实施例对此不做限制。
可选地,所述PUCCH包括N个上行信道(例如目标PUCCH包括N个PUCCH)时,该N个上行信道可以包括PUCCH重复传输。
本申请实施例中,终端设备可以基于第一分段长度,将目标上行信道的传输持续时间划分为一个或多个分段TDW,得到目标上行信道对应的分段TDW。也就是说,目标上行信道的传输持续时间,可以被至少一个分段TDW覆盖。
应理解,第一分段长度可以用于所述终端设备进行时域同步和/或频域同步调整。根据第一分段长度确定目标上行信道对应的分段TDW可以与终端设备进行时域同步和/或频域同步调整的时间间隔具有关联关系。例如,分段TDW的长度可以大于终端设备进行时域同步和/或频域同步的最小时间间隔,或者分段TDW的长度可以小于终端设备能够进行时域同步和/或频域同步的最大时间间隔,本申请实施例对此不做限制。
进一步地,终端设备在确定了分段TDW后,可以为分段TDW进行时域同步和/或频域同步调整,并在进行了时域同步和/或频域同步调整之后发送目标上行信道。
在一些实施例中,若目标上行信道的传输持续时间对应至少一个分段TDW,则终端设备根据所述分段TDW发送目标上行信道,可以通过以下方式实现:
终端设备在通过至少一个分段TDW中的每个分段TDW发送目标上行信道前,为每个分段TDW进行时域同步和/或频域同步调整。
也就是说,终端设备可以为每个分段TDW调整定时同步补偿和/或频偏同步补偿,并在完成定时同步补偿和/或频偏同步补偿之后,发送每个分段TDW对应的上行信道。如此保证终端设备与网络设备的同步精度。
示例性的,参考图5所示,目标上行信道可以包括10次PUSCH重复传输和两个信道间隔(GAP),其中每个PUSCH占用一个时隙,且每个GAP也占用一个时隙,也就是说,目标上行信道可以包括12个时隙。假设第一分段长度为4个时隙,该目标上行信道的传输持续时间可以被划分为3个分段TDW,其中,分段TDW1覆盖目标上行信道的前4个时隙,分段TDW2覆盖目标上行信道的中间4个时隙,分段TDW3覆盖目标上行信道的最后4个时隙。针对第一个分段TDW(即分段TDW1),终端设备需要通过分段TDW1发送目标上行信道的情况下,终端设备可以在传输PUSCH 1之前进行时域同步和/或频域同步调整,并在完成时域同步和/或频域同步调整之后,发送分段TDW1对应的上行信道(即PUSCH 1、PUSCH 2和PUSCH 3)。另外,终端设备通过分段TDW2和分段TDW3发送目标上行信道前,同样需要进行时域同步和/或频域同步调整。
可选地,终端设备进行时域同步和/或频域同步调整,包括:终端设备根据终端设备的位置、公共定时参数和服务卫星星历信息中的至少一项进行时域同步和/或频域同步调整。
可选地,终端设备进行时域同步和/或频域同步调整,包括:终端设备根据公式(1)确定T TA值。
另外,网络设备可以根据第一分段长度确定目标上行信道对应的一个或多个分段TDW,这样,网络设备可以确定终端设备通过所述至少一个分段TDW中的每个分段TDW发送所述目标上行信道前,为所述每个分段TDW进行时域同步和/或频域同步调整。
也就是说,网络设备也可以根据第一分段长度确定目标上行信道对应的分段TDW,在接收到目标上行信道后,可以根据确定的分段TDW得到终端设备进行时域同步和/或频域同步调整的时机,从而根据终端设备进行上行同步的时机进行相应的信道估计。
由此可见,本申请实施例提供的上行传输方法中,终端设备可以根据第一分段长度确定目标上行信道对应的分段TDW,并对每个分段TDW进行时域同步和/或频域同步,如此保证在目标上行信道传输过程中终端设备与网络设备之间同步,同时避免了终端设备频繁地进行时域和/或频域的同步调整所造成的低信道估计增益。
以下详细介绍分段TDW与目标上行信道之间的关系。
在一些实施例中,目标上行信道的传输持续时间对应至少一个分段TDW,至少一个分段TDW中的第一个分段TDW的起始位置为N个上行信道中的第一个上行信道的起始位置。
也就是说,终端设备或网络设备可以从目标上行信道的第一个上行信道的起始位置开始,对目标上行信道的传输持续时间进行划分,得到目标上行信道对应的至少一个分段TDW。应理解,至少一个分段DWT中第一个分段TDW的起始位置与目标上行信道的起始位置相同。
可选地,所述第一个上行信道的起始位置为第一个上行信道的第一个符号。
需要说明的是,符号为可以是时域上最小的时间单元,符号可以是正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号,或者其他时域符号,本申请实施例对此不做限制。
也就是说,本申请实施例中所述至少一个分段TDW中的第一个分段TDW可以从目标上行信道中第一个上行信道的第一个符号开始。
可选地,所述第一个上行信道是根据时域资源分配指示确定的所述N个上行信道中的第一个上行信道;或者,所述第一个上行信道是所述N个上行信道中的第一个有效的上行信道。
应理解,在一些实施例中,第一个上行信道可以是N个上行信道中的第一个配置的上行信道。也就是说,所述至少一个分段TDW的起始位置,可以为N个上行信道中的第一个配置的上行信道起始位置(或第一个符号)。
在另一些实施例中,时域资源分配指示的N个上行信道中存在无效的上行信道,例如,网络设备可以向终端设备指示某个PUSCH为无效信道,在该情况下,第一个上行信道可以是时域资源分配指示确定的N个上行信道中的第一个有效的上行信道。也就是说,所述至少一个分段TDW的起始位置可以是N个上行信道中的第一个有效的上行信道的起始位置(或第一个符号)。
可选地,所述至少一个分段TDW的最后一个分段TDW的结束位置为所述N个上行信道中第N个上行信道的结束位置。也就是说,至少一个分段TDW的最后一个分段TDW的结束位置为N个上行信道中最后一个上行信道的结束位置。
可选地,第N个上行信道的结束位置可以是第N个上行信道的最后一个符号。
在一些实施例中,在目标上行信道的传输持续时间对应至少两个分段TDW的情况下,至少两个分段TDW中的第K+1个分段TDW的起始位置为至少两个分段TDW中的第K个分段TDW的结束位置,K为正整数。
可以理解的是,至少两个分段TDW中每个分段TDW可以是首尾连接,前一个分段TDW的结束位置为后一个分段TDW的起始位置。也就是说,本实施例中,不论前一个分段TDW的结束位置为信道间隙(GAP),还是N个上行信道中某个上行信道的结束位置,后一个分段TDW的起始位置均为前一个分段TDW的结束位置。
示例性的,参考图5所示,假设第一分段长度为4个时隙,根据第一分段长度可以确定目标上行信道包括3个分段TDW。其中,若分段TDW1的结束位置为GAP1的最后一个符号,则分段TDW2的起始位置可以为GAP1的最后一个符号。另外,若分段TDW2的结束位置为PUSCH 7的最后一个符号,则分段TDW3的起始位置可以为该PUSCH 7的最后一个符号
在另一些实施例中,在目标上行信道的传输持续时间对应至少两个分段TDW的情况下,所述至少两个分段TDW中的第K+1个分段TDW的起始位置为所述N个上行信道中的第M个上行信道的起始位置,K为正整数,M为正整数。
可以理解的是,本申请实施例中的至少两个分段TDW中,除了第一个分段TDW,其他的每个分段TDW的起始位置可以是N个上行信道中某个上行信道的起始位置。也就是说,本实施例中,若前一个分段TDW的结束位置第M-1个上行信道与第M个上行信道之间存在GAP,那么后一个分段TDW的起始位置可以不为前一个分段TDW的结束位置,而是为N个上行信道中第M个上行信道的起始位置。其中,第M-1个上行信号和第M个上行信道为上述N个上行信道中相邻的两个上行信道。
示例性的,参考图6所示,假设第一分段长度为4个时隙,根据第一分段长度确定的分段TDW1中最多只能包括3个PUSCH,因此分段TDW1的结束位置为PUSCH 3的最后一个符号。当PUSCH3和PUSCH4之间存在GAP时,分段TDW2的起始位置可以是PUSCH 4的第一个符号。
在又一些实施例中,在目标上行信道的传输持续时间对应至少两个分段TDW的情况下,所述至少两个分段TDW中的第K+1个分段TDW的起始位置为所述N个上行信道中的第M个上行信道所在时间单元的起始位置,K为正整数,M为正整数。
应理解,上行信道的起始位置可以是一个时隙中的某个符号,因此,本实施例的至少两个分段TDW中,除了第一个分段TDW,其他的每个分段TDW的起始位置可以是N个上行信道中某个上行信道所在时间单元的起始位置。
在一些实施例中,第一个分段TDW的起始位置也可以是N个上行信道中第一个上行信道所在时间单元的起始位置。
其中,时间单元可以是一个时隙、半个时隙、多个符号、一个子帧等,本申请实施例对此不做限制。
在本申请一实施例中,目标上行信道的传输持续时间对应至少一个分段TDW,所述至少一个分段TDW中每个分段DTW包括一个或多个实际TDW;
其中,第一分段TDW中第一个实际TDW的起始位置为所述第一分段TDW的起始位置,若发生破坏功率一致性和相位连续性的事件,则所述第一个实际TDW的结束位置为所述事件发生时对应的上行信道的最后一个符号;和/或,
若未发生破坏功率一致性和相位连续性的事件,则所述第一个实际TDW的结束位置为所述第一分段TDW的结束位置;
所述第一分段TDW为所述至少一个分段TDW中的一个分段TDW。
应理解,本申请实施例为了实现联合信道估计,还可以引入实际TDW。需要注意的是,终端设备在每一个实际TDW内需要保持功率一致性和相位一致性,如此,网络设备可以根据每个实际TDW进行联合信道估计,以增强终端设备的上行覆盖。
本申请实施例中,每个分段TDW可以包括一个或多个实际TDW,若某一个分段TDW中未发生破坏功率一致性和相位连续性的事件,则该分段TDW中可以仅包括一个实际TDW。其中,该实际TDW的起始位置即为当前分段TDW的起始位置,该实际TDW的结束位置即为当前分段TDW的结束位置。
另外,若某一个分段TDW中发生了破坏功率一致性和相位连续性的事件,则该分段TDW会被分成多个实际TDW,或者该分段TDW中的实际TDW会提前结束。
具体来说,每个分段TDW中的第一个实际TDW的起始位置可以与当前分段TDW的起始位置相同。在当前分段TDW中发生了一个破坏功率一致性和相位连续性的事件,那么第一个TDW的结束位置可以是该事件发生时正在传输的上行信道的最后一个符号。
当破坏功率一致性和相位连续性的事件发生时,如果终端设备具有重启DMRS绑定的能力,则在事件结束后会创建一个新的实际TDW(也就是分段TDW中包括多个实际TDW)。如果终端设备不具有重启DMRS绑定的能力,则直到该分段TDW结束也不会创建新的实际TDW,也就是说,分段TDW中仅包括一个实际TDW,且该TDW的结束位置为破坏功率一致性和相位连续性的事件发生时正在传输的上行信道的最后一个符号。
在本申请另一实施例中,目标上行信道的传输持续时间对应至少一个分段TDW;
其中,在第一分段TDW中,若发生破坏功率一致性和相位连续性的事件,则所述第一分段TDW的结束位置为所述事件发生时对应的上行信道的最后一个符号;和/或,
若未发生破坏功率一致性和相位连续性的事件,则所述第一分段TDW的结束位置根据所述第一分段长度确定;
所述第一分段TDW为所述至少一个分段TDW中的一个分段TDW。
可选地,当破坏功率一致性和相位连续性的事件发生时,终端设备在事件结束后创建一个新的分段TDW。可选地,终端设备是否创建新的分段TDW根据终端设备能够进行时域同步和/或频域同步调整的最小时间间隔和/或最大时间时间的能力确定。
需要说明的是,本申请实施例中的至少一个分段TDW可以是终端设备根据第一分段长度和目标上行信道确定。其中,至少一个分段TDW中第一个分段TDW的起始位置可以通过上述实施例描述的方式确定,至少一个分段TDW中各个分段TDW之间的关系也可以通过上述实施例描述的方式确定,此处不再赘述。另外,所述至少一个分段TDW中除了最后一个分段TDW,其他TDW的长度可以根据第一分段长度确定。例如,所述至少一个分段TDW中除了最后一个分段TDW,其他TDW的长度均为第一分段长度。
示例性的,参考图7所示,目标上行信道可以包括10次PUSCH重复传输,该目标上行信道对应3个分段TDW:分段TDW1、分段TDW2和分段TDW3。其中,在分段TDW1的PUSCH 2传输时发生了破坏功率一致性和相位连续性的事件1,那么分段TDW1中第一个实际TDW可以在PUSCH2的最后一个符号结束。当前终端设备具有重启DMRS绑定的能力,则终端设备会在PUSCH 2结束后创建一个新的实际TDW,该新的实际TDW的起始位置为PUSCH 3的第一个符号,在分段TDW1结束之前,没有发生破坏功率一致性和相位连续性的事件,因此,该新的实际TDW的结束位置为分段TDW1的结束位置,即PUSCH 4的最后一个符号。
另外,在分段TDW2的PUSCH 7传输时发生了破坏功率一致性和相位连续性的事件2,那么分段TDW2中第一个实际TDW可以在PUSCH 7的最后一个符号结束。终端设备可以在PUSCH 7结束后创建一个新的实际TDW,该新的实际TDW的起始位置为PUSCH 8的第一个符号,在分段TDW2结束之前,没有发生破坏功率一致性和相位连续性的事件,因此,该新的实际TDW的结束位置为分段TDW2的结束位置,即PUSCH 8的最后一个符号。
其中,图7所示的PUSCH传输持续时间中,相同的填充图案表征具有相同的功率一致性和相位连续性。
可选地,破坏功率一致性和相位连续性的事件包括以下中的至少一项:
在TDD频谱中,基于半静态下行/上行配置图案确定的下行时隙或者下行接收或者下行监听;
对于常规CP,两个连续上行信道传输之间的间隔大于13个符号;对于扩展CP,两个连续上行信道传输之间的间隔大于11个符号;
在两个连续上行信道传输之间的间隔没有大于13个符号的情况下,所述终端设备在所述间隔中被调度了除所述目标上行信道外的其他的上行传输;
基于协议定义的碰撞规则,丢弃或取消了所述目标上行信道中的一个或多个上行信道传输;
在所述目标上行信道为PUSCH的情况下,两个连续上行信道传输关联不同的上行波束;
在所述目标上行信道为PUCCH的情况下,两个连续上行信道传输关联不同的上行波束或不同的功控参数;
基于所述终端设备接收到的定时提前命令TAC进行TA调整;
频域跳频处理;
在所述终端设备为半双工FDD紧凑型终端且所述目标上行信道为PUSCH的情况下,基于协议定义的舍弃规则发生的上行信道传输的丢弃或取消,或者,两个连续的上行信道传输之间存在与下行接收或下行监听重叠的符号。
由此可见,本申请实施例提供的传输方法中,终端设备可以在通过每个分段TDW发送目标上行信道前,为每个分段TDW进行时域同步和/或频域同步调整,保证在目标上行信道传输过程中终端设备与网络设备之间同步。同时,终端设备在每个分段TDW中的实际TDW内保持功率一致性和相位连续性,这样,网络设备可以根据每个分段TDW内的实际TDW进行基于DMRS绑定的联合信道估计,提高终端设备的信道估计增益。
在本申请一实施例中,所述目标上行信道传输持续时间对应至少一个名义TDW;所述至少一个名义TDW中每个名义TDW包括一个或多个所述分段TDW;
其中,第一名义TDW中的第一个分段TDW的起始位置为所述第一名义TDW的起始位置;所述第一名义TDW为所述至少一个名义TDW中的一个名义TDW。
应理解,为了与相关技术中基于DMRS绑定的联合信道估计的覆盖增强技术进行兼容,本申请实施例还可以同时引入名义TDW和实际TDW,与上述实施例中的分段TDW进行结合。
这里,目标上行信道的持续传输时间可以对应至少一个名义TDW,该至少一个名义TDW中除了最后一个名义TDW,其他的名义TDW的长度可以是网络设备配置的或者预定义的或者根据预定义的规则计算的,本申请实施例对此不做限制。
可选地,名义TDW的长度是根据第一分段长度确定的。例如,名义TDW的长度小于或等于第一分段长度。
可选地,名义TDW的长度是根据第一分段长度和终端设备能够保持功率一致性和相位连续性的最大持续时间确定的。例如,名义TDW的长度小于或等于第一分段长度和该最大持续时间中的较小值。
在本申请实施例中,终端设备可以根据第一分段长度和名义TDW确定分段TDW。具体地,每个名义TDW可以包括一个或多个分段TDW。其中,每个名义TDW中的第一个分段TDW的起始位置为当前名义TDW的起始位置。另外,每个名义TDW中的最后一个分段TDW的结束位置可以为当前名义TDW的结束位置。
在一些实施例中,所述第一名义TDW中除了第一个分段TDW和最后一个分段TDW之外,其他的分段TDW的长度根据所述第一分段长度确定。
可选地,第一名义TDW中的第一个分段TDW的长度根据所述第一分段长度确定,或者,所述第一名义TDW中的第一个分段TDW的长度根据所述第一名义TDW的前一个名义TDW中的最后一个分段TDW的长度和所述第一分段长度确定。
应理解,在网络设备配置的或者预定义的名义TDW的长度等于第一分段长度时,每个名义TDW中仅包括一个分段TDW,并且目标上行信道对应的至少一个分段TDW(名义TDW)中除了最后一个分段TDW(名义TDW),其他的分段TDW(名义TDW)的长度根据第一分段长度确定,例如其他TDW的长度可以为该第一分段长度。
另外,在网络设备配置的或者预定义的名义TDW的长度大于第一分段长度时,每个名义TDW可以包括多个分段TDW。其中,每个名义TDW包括的多个分段TDW中除了最后一个分段TDW,其他分段TDW的长度可以根据第一分段长度确定,例如其他分段TDW的长度可以为第一分段长度。
示例性的,参考图8所示,目标上行信道包括10次PUSCH重复传输,每个PUSCH占用一个时隙。假设网络设备配置的名义TDW的长度为4个时隙,第一分段长度为3个时隙,按照名义TDW的长度,该目标上行信道的10次PUSCH重复传输可以对应3个名义TDW,其中,名义TDW1和 名义TDW2的长度为4个时隙,名义TDW3的长度为2个时隙。
另外,根据第一分段长度,名义TDW1和名义TDW2中可以分别包括两个分段TDW,其中,名义TDW1中的第一个分段TDW(即分段TDW1)的长度为3个时隙,名义TDW1中的第二个分段TDW(即分段TDW2)的长度为1个时隙。另外,名义TDW2中的第一个分段TDW(即分段TDW3)的长度为3个时隙,名义TDW2中的第二个分段TDW(即分段TDW4)的长度为1个时隙。名义TDW3作为最后一个名义TDW,其长度为2个时隙,该名义TDW3中仅包括一个分段TDW(即分段TDW5)。
或者,在网络设备配置的或者预定义的名义TDW的长度大于第一分段长度时,每个名义TDW中的第一个分段TDW的长度可以根据当前名义TDW的前一个名义TDW中的最后一个分段TDW的长度和所述第一分段长度确定。在该场景下,如果还以图8示例,则分段TDW1对应PUSCH1、PUSCH2和PUSCH3;分段TDW2对应PUSCH4、PUSCH5和PUSCH6;分段TDW3对应PUSCH7、PUSCH8和PUSCH9;分段TDW4对应PUSCH10。
在网络设备配置的或者预定义的名义TDW的长度小于第一分段长度时,目标上行信道对应的至少一个分段TDW中的部分分段TDW可能会被某些名义TDW截断。示例性的,参考图9所示,名义TDW的长度为3个PUSCH的传输持续时间,第一分段长度为4个PUSCH的传输持续时间。目标上行信道的10次PUSCH重复传输可以对应3个分段TDW。其中,分段TDW1被名义TDW1截断,分段TDW2被名义TDW2截断,分段TDW3被名义TDW3截断。
或者,在该场景中,每个名义TDW中的第一个分段TDW的长度可以根据当前名义TDW的前一个名义TDW中的最后一个分段TDW的长度和所述第一分段长度确定。
可选地,每个名义TDW中除了第一个分段TDW和最后一个分段TDW之外,其他的分段TDW的长度根据所述第一分段长度确定。每个名义TDW中的第一个分段TDW的长度可以是第一分段长度减去前一个名义TDW中的最后一个分段TDW的长度。
参考图9所示,分段TDW2包括名义TDW2中PUSCH5和PUSCH 6的传输持续时间以及名义TDW3中PUSCH7和PUSCH 8的传输持续时间,即名义TDW3中第一个分段TDW为第一分段长度减去名义TDW2中包括的2个PUSCH的传输持续时间。
可选地,本申请实施例中,分段TDW根据第一分段长度确定,终端设备为每个分段TDW进行时域同步和/或频域同步调整。或者说,分段TDW和名义TDW独立确定,不论名义TDW的长度大于第一分段长度还是小于第一分段长度,终端设备都需要根据基于第一分段长度确定的分段TDW进行时域同步调整和/或频域同步调整。
可选地,本申请实施例中,终端设备需要对每个分段TDW进行时域同步调整和/或频域同步调整。还可以对每个名义TDW进行时域同步调整和/或频域同步调整。也就是说,在通过每个名义TDW进行目标上行信道的传输之前,为每个名义TDW进行时域同步和/或频域同步调整。
本申请实施例中,目标上行信道的传输持续时间对应至少一个名义TDW,所述至少一个名义TDW中每个名义TDW可以包括一个或多个实际TDW;
其中,第一名义TDW中第一个实际TDW的起始位置为所述第一名义TDW的起始位置,若发生破坏功率一致性和相位连续性的事件,则所述第一个实际TDW的结束位置为所述事件发生时对应的上行信道的最后一个符号;和/或,
若未发生破坏功率一致性和相位连续性的事件,则所述第一个实际TDW的结束位置为所述第一名义TDW的结束位置;
所述第一名义TDW为所述至少一个名义TDW中的一个名义TDW。
应理解,至少一个名义TDW中每个名义TDW可以包括一个或多个实际TDW。终端设备可以在每一个实际TDW内需要保持功率一致性和相位一致性,网络设备可以根据每个实际TDW进行联合信道估计,以增强终端设备的上行覆盖。
具体地,若某一个名义TDW中未发生破坏功率一致性和相位连续性的事件,则该名义TDW中仅包括一个实际TDW。其中,该实际TDW的起始位置即为当前名义TDW的起始位置,该实际TDW的结束位置即为当前名义TDW的结束位置。
若某一个名义TDW中发生了破坏功率一致性和相位连续性的事件,则该名义TDW会被分成多个实际TDW,或者该名义TDW中的实际TDW会被提前结束。
具体来说,某一个名义TDW中的第一个实际TDW的起始位置可以与当前名义TDW的起始位置相同。在当前名义TDW中发生了一个破坏功率一致性和相位连续性的事件,那么第一个TDW的结束位置可以是该事件发生时正在传输的上行信道的最后一个符号。
其中,当破坏功率一致性和相位连续性的事件发生时,如果终端设备具有重启DMRS绑定的能力,则在事件结束后会创建一个新的实际TDW。如果终端设备不具有重启DMRS绑定的能力,则直到该名义TDW结束也不会创建新的实际TDW。
在一些实施例中,破坏功率一致性和相位连续性的事件包括以下中的至少一项:
在TDD频谱中,基于半静态下行/上行配置图案确定的下行时隙或者下行接收或者下行监听;
对于常规CP,两个连续上行信道传输之间的间隔大于13个符号;对于扩展CP,两个连续上行信道传输之间的间隔大于11个符号;
在两个连续上行信道传输之间的间隔没有大于13个符号的情况下,所述终端设备在所述间隔中被调度了除所述目标上行信道外的其他的上行传输;
基于协议定义的碰撞规则,丢弃或取消了所述目标上行信道中的一个或多个上行信道传输;
在所述目标上行信道为PUSCH的情况下,两个连续上行信道传输关联不同的上行波束;
在所述目标上行信道为PUCCH的情况下,两个连续上行信道传输关联不同的上行波束或不同的功控参数;
基于所述终端设备接收到的定时提前命令TAC进行TA调整;
频域跳频处理;
在所述终端设备为半双工FDD紧凑型终端且所述目标上行信道为PUSCH的情况下,基于协议定义的舍弃规则发生的上行信道传输的丢弃或取消,或者,两个连续的上行信道传输之间存在与下行接收或下行监听重叠的符号。
在另一些实施例中,破坏功率一致性和相位连续性的事件还可以包括:通过第一名义TDW传输的上行信道被任一分段TDW中断。也就是说,在进行目标上行信道传输过程中,通过任一个名义TDW传输的上行信道被分段TDW中断后,当前名义TDW中的实际TDW会结束。
示例性的,参考图10情况1所示,名义TDW1中包括两个分段TDW:分段TDW1和分段TDW2。当分段TDW1在PUSCH 3的最后一个符号结束后,名义TDW1中的第一个实际TDW(实际TDW1)也会在PUSCH 3的最后一个符号结束,进一步,假设终端设备具有重启DMRS绑定的能力,终端设备在PUSCH 3结束后建立一个新的实际TDW(实际TDW2),该实际TDW2的结束位置为名义TDW1的结束位置。
另外,名义TDW2中也包括两个分段TDW:分段TDW3和分段TDW4。若在传输PUSCH 5时发生破坏功率一致性和相位连续性的事件,则名义TDW2中第一个实际TDW(实际TDW3)的结束位置为该事件发生时传输的PUSCH 5的最后一个符号。终端设备可以在PUSCH 5结束之后,建立名义TDW2的第二个实际TDW(即实际TDW4)。进一步,通过名义TDW2传输的PUSCH 7被分段TDW3中断,那么名义TDW2中的第二个实际TDW(即实际TDW4)的结束位置为PUSCH 7的最后一个符号。接着,终端设备还可以为名义TDW2建立第三个实际TDW(即实际TDW5),在名义TDW2结束之前没有发生破坏功率一致性和相位连续性的事件,该实际TDW5的结束位置为名义TDW2的结束位置。
可选地,在该情况1中,终端设备在发送目标PUSCH前,为分段TDW1、分段TDW2、分段TDW3、分段TDW4和分段TDW5中每个分段TDW进行时域同步和/或频域同步调整。
示例性的,参考图10情况2所示,名义TDW1中同样包括两个分段TDW:分段TDW1和分段TDW2。当分段TDW1在PUSCH 3的最后一个符号结束后,名义TDW1中的第一个实际TDW(实际TDW1)也会在PUSCH 3的最后一个符号结束,进一步,假设终端设备具有重启DMRS绑定的能力,终端设备在PUSCH 3结束后建立一个新的实际TDW(实际TDW2),该实际TDW2的结束位置为名义TDW1的结束位置。
另外,分段TDW2被名义TDW2中断。在名义TDW2中,若在传输PUSCH 5时发生破坏功率一致性和相位连续性的事件,则名义TDW2中第一个实际TDW(实际TDW3)的结束位置为该事件发生时传输的PUSCH 5的最后一个符号。终端设备可以在PUSCH 5结束之后,建立名义TDW2的第二个实际TDW(即实际TDW4)。进一步,通过名义TDW2传输的PUSCH 6被分段TDW2中断,那么名义TDW2中的第二个实际TDW(即实际TDW4)的结束位置为PUSCH 6的最后一个符号。接着,终端设备还可以根据分段TDW3为名义TDW2建立第三个实际TDW(即实际TDW5),在名义TDW2结束之前没有发生破坏功率一致性和相位连续性的事件,该实际TDW5的结束位置为名义TDW2的结束位置。
另外,在名义TDW3中,PUSCH传输被分段TDW3中断,因此名义TDW3中包括两个实际TDW(即实际TDW6和实际TDW7)。
可选地,在该情况2中,终端设备在发送目标PUSCH前,为分段TDW1、分段TDW2、分段TDW3和分段TDW4中每个分段TDW进行时域同步和/或频域同步调整。
需要说明的是,终端设备在每个实际TDW中均保持功率一致性和相位连续性。图10情况1和图10情况2所示的PUSCH传输持续时间中,相同的填充图案表征具有相同的功率一致性和相位连续性。
可选地,当目标上行信道被分段TDW中断时,终端设备必须支持重启DMRS绑定。
可选地,当目标上行信道被分段TDW中断时,终端设备是否支持重启DMRS绑定是一种可选的能力。
由此可见,本申请实施例提供的传输方法中,终端设备可以在通过每个分段TDW发送目标上行信道前,为每个分段TDW进行时域同步和/或频域同步调整,保证在目标上行信道传输过程中终端设备与网络设备之间同步。同时,终端设备在每个分段TDW中的实际TDW内保持功率一致性和相位连续性,这样,网络设备可以根据每个分段TDW内的实际TDW进行基于DMRS绑定的联合信道估计,提高终端设备的信道估计增益。
在本申请一实施例中,终端设备可以在每个所述分段TDW内禁止基于所述终端设备的位置、公共定时参数和服务卫星星历信息中的至少一项进行时域同步和/或频域同步调整;和/或,
所述终端设备在每个所述分段TDW内禁止基于接收到的定时提前命令(Timing Advance Comman,TAC)进行TA调整。
可以理解的是,在传输目标上行信道的过程中,终端设备可以为每个分段TDW进行时域同步和/或频域同步调整。然而,本申请实施例中经过时域同步和/或频域同步之后的每个分段TDW,在其分段TDW内终端设备可以禁止进行时域/频域的调整,这样,网络设备可以利用每个分段TDW中接收到的信息进行联合信道估计,以保障基于DMRS绑定的联合信道估计的增益。
可选地,每个分段TDW内终端设备禁止进行时域/频域的调整可以包括:终端设备在每个分段TDW内禁止基于终端设备的位置、公共定时参数和服务卫星星历信息中的至少一项进行时域同步和/或频域同步调整;和/或,终端设备在每个分段TDW内禁止终端设备基于接收到的定时提前命令进行TA调整。
可选地,公共定时参数和服务卫星星历信息可以是高层配置的例如是网络设备通过系统消息配置的。
对应的,网络设备在基于第一分段长度确定了目标上行信道的多个分段TDW之后,可以确定终端设备在每个分段TDW中未基于所述终端设备的位置、公共定时参数和服务卫星星历信息中的至少一项进行时域同步和/或频域同步调整;和/或,确定终端设备在每个所述分段TDW内未基于接收到的定时提前命令TAC进行TA调整。
也就是说,网络设备也可以根据第一分段长度确定多个分段TDW,根据多个分段TDW确定终端设备进行时域同步和/或频域同步的准确时机,进而网络设备可以根据多个分段TDW接收到的信息进行基于DMRS绑定的联合信道估计。
由此可见,本申请实施例提供的上行传输方法中,网络设备和终端设备根据第一分段长度,确定终端设备进行时域同步和/或频域同步的时机,从而在NTN系统中实现基于DMRS绑定的联合信道估计的覆盖增强技术,达到增强终端设备的覆盖的目的。
应理解,在一些实施例中,终端设备可以禁止在每个分段TDW内执行网络设备发送的TAC。例如,当终端设备接收到TAC,并确定应从某个分段TDW内的上行信道传输开始应用该TAC对应的TA调整时,终端设备不能在该分段TDW内进行对应的TA调整。在另一些实施例中,终端设备在接收到指示在分段TDW内进行TA调整的TAC时,也可以对该TAC进行响应。例如,当终端设备接收到TAC,并确定应从某个分段TDW内的上行信道传输开始应用该TAC对应的TA调整时,终端设备可以进行对应的TA调整。
在一种可能的实现方式中,当终端设备被指示在第一分段TDW内基于接收到的TAC进行TA调整时,终端设备可以确定在所述第一分段TDW内执行所述TAC;
其中,第一分段TDW为多个分段TDW中的任意一个。
也就是说,在通过多个分段TDW发送目标上行信道的过程中,当终端设备接收到TAC,并且该TAC要求终端设备在某个分段时域窗口内进行TA调整,那么终端设备可以在该分段TDW内执行网络设备发送的TAC,进行TA调整。
示例性的,参考图11所示,若终端设备接收到TAC,根据TAC应用时间,该TAC指示应在分段TDW3内的某个PUSCH开始进行TA调整,则终端设备可以在分段TDW3的该PUSCH的第一 个符号执行TAC,例如在图11所示的PUSCH6的第一个符号进行TA调整,这样,PUSCH5和PUSCH6可以不再保持功率一致性和/或相位连续性。
由此可见,本申请实施提供的上行传输方法中,终端设备可以根据网络设备的指示,灵活地进行TA调整。
在另一种可能的实现方式中,所述终端设备被指示在第一分段TDW内基于接收到的TAC进行TA调整时,所述终端设备确定在通过第二分段TDW发送所述目标上行信道前基于所述TAC进行TA调整;
其中,所述第一分段TDW为所述多个分段TDW中的一个分段TDW;所述第二分段TDW为位于所述第一分段TDW之后,且与所述第一分段TDW相邻的分段TDW。
也就是说,在上述多个分段TDW发送目标上行信道的过程中,当终端设备收到网络设备发送的TA命令且被要求在某个分段TDW内进行TA调整,那么终端设备可以从当前分段TDW的下一个分段TDW开始执行该TAC。
示例性的,参考图12所示,当终端设备接收到的TAC指示,根据TAC应用时间,终端设备应在分段TDW3内进行TA调整时,终端设备可以在分段TDW3结束之后,通过分段TDW4传输目标上行信道之前时执行TA调整。从图12可以看出,TAC实际执行时间为传输PUSCH 7之前。
对应的,所述网络设备向终端设备发送定时提前命令TAC,若所述终端设备应在第一分段TDW内基于所述TAC指示进行TA调整,则所述网络设备确定所述终端设备在通过第二分段TDW发送所述目标上行信道前基于所述TAC进行TA调整;
其中,所述第一分段TDW为所述多个分段TDW中的一个分段TDW;所述第二分段TDW为在所述第一分段TDW之后,与所述第一分段TDW相邻的分段TDW。
也就是说,当网络设备向终端设备发送指示终端设备在某个分段TDW内进行TA调整的TAC时,网络设备与终端设备约定不在TAC所指示的分段TDW中执行该TAC,而是在TAC所指示的分段TDW的下一个TDW执行TAC。如此。可以在分段TDW中保持TA不变,维持功率一致性和相位连续性的情况下,对TAC进行响应。提高了终端设备对信息处理的灵活性。
在一些实施例中,步骤410之前,终端设备还可以执行以下步骤:
终端设备向网络设备发送能力信息;所述能力信息包括第一能力信息和/或第二能力信息;
所述第一能力信息用于指示所述终端设备能够进行时域同步和/或频域同步的最小时间间隔;和/或,所述终端设备能够进行时域同步和/或频域同步的最大时间间隔;
所述第二能力信息用于指示述终端设备能够保持功率一致性和相位连续性的最大持续时间。
可选地,所述终端设备能够进行时域同步和/或频域同步调整的最小时间间隔,包括:所述终端设备基于所述终端设备的位置、公共定时参数和服务卫星星历信息中的至少一项,能够进行时域同步和/或频域同步调整的最小时间间隔。
可选地,所述终端设备能够进行时域同步和/或频域同步调整的最大时间间隔,包括:所述终端设备基于所述终端设备的位置、公共定时参数和服务卫星星历信息中的至少一项,能够进行时域同步和/或频域同步调整的最大时间间隔。
需要说明的是,第一能力信息可以通过显示或隐式的方式指示终端设备能够进行时域同步和/或频域同步的最小时间间隔;和/或,所述终端设备能够进行时域同步和/或频域同步的最大时间间隔,第二能力信息也可以通过显示或隐式的方式指示终端设备能够保持功率一致性和相位连续性的最大持续时间。本申请实施例对指示的方式不做限制。
可选地,第一分段长度可以是根据第一能力信息和/或第二能力信息确定的。示例性的,第一分段长度是终端设备根据第一能力信息和/或第二能力信息计算得到的,或者,第一分段长度是网络设备根据第一能力信息和/或第二能力信息为终端设备配置的。本申请实施例对此不做限制。
本申请实施例提供的上行传输方法中,终端设备和/或网络设备,可以根据终端设备的实际能力确定划分分段TDW的第一分段长度。这样,根据第一分段长度确定的分段TDW能够适应终端设备的实际能力,保证了在目标上行信道传输过程中终端设备与网络设备之间时刻保持同步,同时避免了终端设备频繁地进行时域和/或频域的同步调整所造成的低信道估计增益。
