Description

用于无线通信的电子设备和方法、计算机可读存储介质
本申请要求于2021年8月27日提交中国专利局、申请号为202110997075.1、发明名称为“用于无线通信的电子设备和方法、计算机可读存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本公开涉及无线通信技术领域，具体地涉及在基站向用户设备重传定时提前量的过程中定时提前量被更新的情况下，向用户设备正确地传送更新后的定时提前量。更具体地，涉及一种用于无线通信的电子设备和方法、计算机可读存储介质。
背景技术
在无线通信环境中，定时提前量(TA，Timing advance)一般用于用户设备(UE)上行传输，指为了将UE的上行传输包在希望的时间到达基站，预估由于距离引起的射频传输时延，提前相应时间发出数据包。
TA错误会引起基站处产生符号间干扰(ISI，inter-symbol-interfering)。当ISI大到一定程度会导致解码错误，导致解码失败，降低UE的传输效率，影响用户体验。
存在很多TA快速变化的场景。例如，由于基站例如卫星的移动导致基站与UE之间的相对位置不断变化，从而导致TA的变化非常频繁。又例如，在高铁，飞机等UE快速移动场景中，由于UE的移动导致基站与UE之间的相对位置不断变化，从而导致TA的变化非常频繁。
在现有技术中，基站通过媒体接入控制控制元素(MAC CE)以定时提前组(TAG)级对每个用户设备进行TA更新，MAC CE包含在物理下行共享信道(PDSCH)中进行发送,PDSCH需要混合自动重传请求(HARQ)确认(ACK)反馈，而上行调度承载在下行链路控制信息(DCI)中进行发送，因此即使在发完TA指令后的下一个时隙就进行上行调度，当往返延迟(RTD)较大时，会带来TA失效的问题。
另外，由于信道中的噪声和干扰等影响，包含TA命令的传输块(TB)可能无法被用户设备正确接收，因此需要重传TA，而在TA快速变化的场景下TA可能被更新，如果在重传中仍然传送原TA，则会导致UE端TA错误。
图1是示出现有技术中的传输定时提前量的示意图。
如图1所示，在时刻T0，基站(例如卫星)利用MAC CE向UE初传承载相对于T0的TA(适合于T0的TA)的TB。在时刻T1，UE没有接收到DCI或者没有正确地解码，因此，UE针对承载相对于T0的TA的TB而发送NACK。在时刻T2，基站向UE重传TB，该TB仍然承载相对于T0的TA。在时刻T3，UE正确地接收TB。然后，UE从所接收到的TB中提取出TA，并且将所提取出的TA解释为可应用于T3。然而，所提取出的TA实际上仅适用于T1，由于卫星的移动导致在T3时刻TA发生变化，因此，所提取出的TA并不适用于T3。UE应用了适合于T0的TA来在T3时刻进行上行传输，因此，UE应用了错误的TA。

在下文中将结合附图对本发明的示范性实施例进行描述。为了清楚和简明起见，在说明书中并未描述实际实施方式的所有特征。然而，应该了解，在开发任何这种实际实施例的过程中必须做出很多特定于实施方式的决定，以便实现开发人员的具体目标，例如，符合与系统及业务相关的那些限制条件，并且这些限制条件可能会随着实施方式的不同而有所改变。此外，还应该了解，虽然开发工作有可能是非常复杂和费时的，但对得益于本公开内容的本领域技术人员来说，这种开发工作仅仅是例行的任务。
在此，还需要说明的一点是，为了避免因不必要的细节而模糊了本发明，在附图中仅仅示出了与根据本发明的方案密切相关的设备结构和/或处理步骤，而省略了与本发明关系不大的其他细节。
图2示出了根据本公开的一个实施例的用于无线通信的电子设备的 功能模块框图。
如图2所示，电子设备200包括：处理单元201，其可以在利用混合自动重传请求机制要向与电子设备200相关的装置的服务范围内的用户设备重传有关用户设备的第一定时提前量的第一信息的过程中，在第一定时提前量被更新的情况下，向用户设备传送有关第二定时提前量的第二信息，其中，第二定时提前量是更新后的第一定时提前量。
其中，处理单元201可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片。
电子设备200可以作为无线通信系统中的网络侧设备，具体地例如可以设置在基站侧或者可通信地连接到基站。在电子设备200设置在基站侧或者可通信地连接到基站的情况下，与电子设备200相关的装置可以是基站。这里，还应指出，电子设备200可以以芯片级来实现，或者也可以以设备级来实现。例如，电子设备200可以工作为基站本身，并且还可以包括诸如存储器、收发器(未示出)等外部设备。存储器可以用于存储基站实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如，用户设备、其他基站等等)间的通信，这里不具体限制收发器的实现形式。
根据本公开的无线通信系统可以是5G NR(New Radio，新空口)通信系统。进一步，根据本公开的无线通信系统可以包括非地面网络(Non-terrestrial network，NTN)。可选地，根据本公开的无线通信系统还可以包括地面网络(Terrestrial network，TN)。另外，本领域技术人员可以理解，根据本公开的无线通信系统还可以是4G或3G通信系统。
电子设备200利用HARQ机制向用户设备传送有关定时提前量的信息。例如，电子设备200在初传时向用户设备传送有关用户设备的第一定时提前量的第一信息。由于信道中的噪声和干扰等影响，用户设备可能不能正确接收第一信息，因此电子设备200需要重传第一信息。如果在要重传第一信息的过程中第一定时提前量被更新，则电子设备200传送有关第二定时提前量(即，更新后的第一定时提前量)的第二信息，以向用户设备正确地传送更新后的定时提前量。
例示而非限制，在TA快速变化的场景中，在要重传第一信息的过程中第一定时提前量可能被更新。TA快速变化的场景例如：由于基站例如 卫星的移动导致基站与UE之间的相对位置不断变化，从而导致TA的变化非常频繁；或者，在高铁、飞机等UE快速移动场景中，由于UE的移动导致基站与UE之间的相对位置不断变化，从而导致TA的变化非常频繁。
例如，电子设备200可以通过MAC CE向用户设备传送包括有关定时提前量的信息的TB。
在现有技术中，如结合图1所描述的，在TA快速变化的场景下即使TA已经被更新，基站在重传中仍然传送原TA，从而导致UE端TA错误。
然而，根据本公开实施例的电子设备200可以在重传有关用户设备的定时提前量的过程中，在定时提前量已经被更新的情况下，向用户设备正确地传送更新后的定时提前量，从而使得UE能以更新后的定时提前量进行上行传输。
作为示例，与电子设备200相关的装置可以是卫星。与电子设备200相关的装置还可以是车联网中的设备等等，这里不再累述。
作为示例，处理单元201可以被配置为在用于重传的第一HARQ进程中所要传送的信息是第一信息的情况下，调用与第一HARQ进程不同的第二HARQ进程来传送第二信息。
用于初传第一信息的HARQ进程和要用于重传第一信息的HARQ进程是同一HARQ进程，在下文中，将其标记为第一HARQ进程。
在用于重传的第一HARQ进程中所要传送的信息是第一信息的情况下，重传的TB中包括的定时提前量与初传的TB中包括的定时提前量相同，不能反映更新后的定时提前量。
由上可知，在用于重传的第一HARQ进程中所要传送的信息是第一信息的情况下，电子设备200通过调用与用于重传的第一HARQ进程不同的第二HARQ进程，将用于重传的第一HARQ进程中包括的定时提前量覆盖掉，从而向用户设备正确地传送更新后的定时提前量。
作为示例，第一信息是第一定时提前量的值，以及第二信息是第二定时提前量的值。在现有技术中，定时提前量是通过以上一次传输的定时提前量为基准而进行差分的方式来传输的。在基站无法预知重传是否可以被用户设备正确接收的情况下，无法确定差分的基准值。而在根据 本公开的实施例中，用户设备接入与电子设备200相关的装置后，定时提前量始终以绝对值而非差分的方式被传输，因此，即使电子设备200无法预知在用于重传的第一HARQ进程中所传送的信息是否可以被用户设备正确接收的情况下，用户设备也可以直接使用通过第二HARQ进程接收到的第二定时提前量。
作为示例，第一信息是第一定时提前量与用户设备初始接入与电子设备200相关的装置时的初始定时提前量之间的差值，以及第二信息是第二定时提前量与初始定时提前量之间的差值。在用户设备初始接入与电子设备200相关的装置时，该装置向用户设备发送包括初始定时提前量的msg.2或msgB，msg.2和msg.B具有较高的可靠性，其中，msg.2是随机接入过程四步握手过程中的第二步，msg.B是随机接入过程两步握手过程中的第二步。在根据本公开的实施例中，不是以上一次传输的定时提前量为基准而进行差分的方式来传输定时提前量，而是以具有更高可靠性的初始定时提前量为基准而进行差分的方式来传输定时提前量。因此，即使电子设备200无法预知在用于重传的第一HARQ进程中所传送的信息是否可以被用户设备正确接收的情况下，用户设备也可以基于通过第二HARQ进程接收到的第二信息来正确地获得第二定时提前量。
作为示例，第二信息是第二定时提前量与被用户设备正确接收并使用的定时提前量之间的差值，以及处理单元201可以被配置为通过DCI信令向用户设备告知：忽略在第一HARQ进程中接收到的有关定时提前量的信息，而基于所接收到的第二信息和被用户设备正确接收并使用的定时提前量来获得第二定时提前量。例如，被用户设备正确接收并使用的定时提前量是电子设备200所确定的被用户设备正确接收并使用的定时提前量。在根据本公开的实施例中，即使电子设备200无法预知在用于重传的第一HARQ进程中所传送的信息是否可以被用户设备正确接收的情况下，电子设备200通过向用户设备告知忽略在第一HARQ进程中接收到的有关定时提前量的信息，通知用户设备基于所接收到的第二信息和被用户设备正确接收并使用的定时提前量来获得第二定时提前量。
作为示例，第二信息是所述第二定时提前量与被用户设备正确接收并使用的定时提前量之间的差值，以及处理单元201可以被配置为向用户设备发送通过加扰传输-无线网络临时标识(INT-RNTI)加扰的DCI，以向用户设备告知在第一HARQ进程中传送的、承载第一信息的MAC  CE所在的时频资源无效，从而向用户设备告知基于第二信息和被用户设备正确接收并使用的定时提前量来获得第二定时提前量。例如，被用户设备正确接收并使用的定时提前量是电子设备200所确定的被用户设备正确接收并使用的定时提前量。在根据本公开的实施例中，即使电子设备200无法预知重传是否可以被用户设备正确接收的情况下，电子设备200通过向用户设备告知在第一HARQ进程中传送的、承载第一信息的MAC CE所在的时频资源无效，通知用户设备基于所接收到的第二信息和被用户设备正确接收并使用的定时提前量来获得第二定时提前量。
作为示例，处理单元201可以被配置为在用于重传的第一HARQ进程中所要传送的信息是第一信息的情况下，在用于重传的第一HARQ进程中传送第二信息而不传送第一信息。
如果用于重传的第一HARQ进程中所将要传送的信息仍然是第一信息，则重传的TB中要包括的定时提前量与初传的TB中包括的定时提前量相同，而不能反映更新后的定时提前量。因此，在这种情况下，电子设备200在用于重传的第一HARQ进程中传送与更新后的定时提前量有关的第二信息而不传送第一信息。
由上可知，电子设备200通过在用于重传的第一HARQ进程传送与更新后的定时提前量有关的信息，从而向用户设备正确地传送更新后的定时提前量。
作为示例，处理单元201可以被配置为向用户设备发送通过INT-RNTI加扰的DCI，以向用户设备告知在用于初传的第一HARQ进程中传送的、承载第一信息的MAC CE所在的时频资源无效，从而向用户设备告知在接收到第二信息之后，不将第一信息和第二信息进行软合并。
电子设备200使用INT-RNTI加扰的DCI格式告诉用户设备例如哪些物理资源块(PRB)和正交频分复用(OFDM)符号是没用的，从而把在用于初传的第一HARQ进程中传送的TB中MAC CE所在的时频资源无效掉。这样，用户设备在接收到这个TB的重传的时候，读取与更新后的定时提前量有关的第二信息，由于电子设备200在用于初传的第一HARQ进程中传送的第一信息和在用于重传的第一HARQ进程中传送的第二信息不同，用户设备不会将在初传中接收到的第一信息与在重传中接收到的第二信息进行软合并，以保证用户设备将与第二信息有关的更 新后的定时提前量作为其用于上行传输的定时提前量。此外，用户设备可以对除了定时提前量之外的、在初传中接收到的时频资源与在重传中接收到的对应时频资源进行软合并，以提高接收的可靠性。
作为示例，处理单元201可以被配置为基于码块组(CBG)来传送第二信息，以及在用于指示重传的DCI中，将码块组缓存清理信息(CBGFI)设置为指示用于重传的第一HARQ进程中传送的所有CBG均不与用于初传的第一HARQ进程中传送的对应CBG进行软合并的值。
在现有标准中，CBGFI的比特数为1个。CBGFI如果为0，指示重传的CBG和之前收到的CBG不进行软合并；CBGFI如果为1，指示重传的CBG可以和之前收到的CBG进行软合并。
在根据本公开实施例的电子设备200中，由于在用于初传的第一HARQ进程中传送的第一信息和在用于重传的第一HARQ进程中传送的第二信息不同，因此，可以将CBGFI的值置0，从而用户设备不会将第一信息和第二信息进行软合并，以保证用户设备将与第二信息有关的更新后的定时提前量作为其用于上行传输的定时提前量。
作为示例，处理单元201可以被配置为基于CBG来传送第二信息，以及将用于指示重传的DCI中的码块组缓存清理信息CBGFI的比特数扩展为与码块组传输信息CBGTI的比特数相同，以及将CBGFI中的、与CBGTI中指示包括第二信息的CGB的比特所对应的比特设置为以下值：该值指示在用于重传的第一HARQ进程中传送的包括第二信息的CBG与在用于初传的第一HARQ进程中传送的对应CBG不进行软合并。
如上所述，在现有标准中，CBGFI的比特数为1个。而在根据本公开实施例的电子设备200中，可以对CBGFI的比特数进行扩展，即将CBGFI的比特数扩展为与码块组传输信息CBGTI的比特数相同。由于电子设备200在用于初传的第一HARQ进程中传送的第一信息和在用于重传的第一HARQ进程中传送的第二信息不同，因此，可以将包含定时提前量的CBG对应的CBGFI置零，从而用户设备不对经由用于重传的第一HARQ进程接收的包括第二信息的CBG与经由用于初传的第一HARQ进程接收的对应CBG进行软合并，以保证用户设备将与第二信息有关的更新后的定时提前量作为其用于上行传输的定时提前量。
作为示例，处理单元201还可以被配置为将CBGFI的与在用于重传 的第一HARQ进程中传送的CBG对应的比特中的、除了与包括第二信息的CGB对应的比特之外的比特设置为以下值：该值指示用于重传的第一HARQ进程中传送的CBG与用于初传的第一HARQ进程中传送的对应CBG进行软合并。
电子设备200可以将扩展后的CBGFI中的、除了与定时提前量对应的CBGFI之外的其他CBGFI值置为1，即，可以对除了定时提前量之外的、在初传中接收到的CBG与在重传中接收到的对应CBG中的时频资源进行软合并，从而提高了所接收到的时频资源的可靠性。
本公开还提供了一种根据另一个实施例的用于无线通信的电子设备。图3示出了根据本公开的另一个实施例的用于无线通信的电子设备300的功能模块框图。如图3所示，电子设备300包括：通信单元301，其可以在利用HARQ机制要从为电子设备300提供服务的网络侧设备重新接收有关电子设备300的第一定时提前量的第一信息的过程中，在第一定时提前量被更新的情况下，从网络侧设备接收有关第二定时提前量的第二信息，其中，第二定时提前量是更新后的第一定时提前量。
其中，通信单元301可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片。
电子设备300例如可以设置在用户设备(UE)侧或者可通信地连接到用户设备。这里，还应指出，电子设备300可以以芯片级来实现，或者也可以以设备级来实现。例如，电子设备300可以工作为用户设备本身，并且还可以包括诸如存储器、收发器(图中未示出)等外部设备。存储器可以用于存储用户设备实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如，基站、其他用户设备等等)间的通信，这里不具体限制收发器的实现形式。基站例如可以是eNB或gNB。
作为示例，网络侧设备可以是基站，例如，网络侧设备可以是根据本公开实施例的电子设备200。
电子设备300利用HARQ机制从网络侧设备接收有关定时提前量的信息。例如，电子设备300从网络侧设备接收经由初传所传送的有关第一定时提前量的第一信息。由于信道中的噪声和干扰等影响，电子设备 300可能不能正确接收第一信息，因此电子设备300需要重新接收第一信息。如果在要重新接收第一信息的过程中第一定时提前量被更新，则电子设备300接收有关第二定时提前量(即，更新后的第一定时提前量)的第二信息，以保证接收更新后的定时提前量。
根据本公开实施例的电子设备300可以在重新接收定时提前量的过程中，在定时提前量已经被更新的情况下，从网络侧设备接收更新后的定时提前量，从而使得电子设备300能以更新后的定时提前量进行上行传输。
作为示例，通信单元301可以被配置为在经由用于重传的第一HARQ进程接收到的信息是第一信息的情况下，经由与第一HARQ进程不同的第二HARQ进程来接收第二信息。
在经由用于重传的第一HARQ进程接收到的信息是第一信息的情况下，电子设备300能够经由第二HARQ进程接收更新后的定时提前量。
作为示例，第一信息是第一定时提前量的值，以及第二信息是第二定时提前量的值。由此，电子设备300可以直接使用经由第二HARQ进程接收到的第二定时提前量作为其用于上行传输的定时提前量。
作为示例，第一信息是第一定时提前量与电子设备300初始接入网络侧设备时的初始定时提前量之间的差值，以及第二信息是第二定时提前量与初始定时提前量之间的差值。由于初始定时提前量具有更高的可靠性，因此电子设备300可以基于初始定时提前量和第二信息更可靠地获得第二定时提前量。
作为示例，第二信息是第二定时提前量与被电子设备300正确接收并使用的定时提前量之间的差值，以及通信单元301可以被配置为通过DCI信令被告知：忽略在第一HARQ进程中接收到的有关定时提前量的信息，而基于所接收到的第二信息和被电子设备300正确接收并使用的定时提前量来获得第二定时提前量。由此，电子设备300能够基于所接收到的第二信息和被电子设备300正确接收并使用的定时提前量来获得第二定时提前量。
作为示例，第二信息是第二定时提前量与被电子设备300正确接收并使用的定时提前量之间的差值，以及通信单元301可以被配置为经由通过INT-RNTI加扰的DCI被告知：网络侧设备在第一HARQ进程中传 送的、承载第一信息的MAC CE所在的时频资源无效，从而电子设备300基于第二信息和被电子设备300正确接收并使用的定时提前量来获得第二定时提前量。由此，电子设备300能够基于所接收到的第二信息和被电子设备300正确接收并使用的定时提前量来获得第二定时提前量。
作为示例，通信单元301可以被配置为经由用于重传的第一HARQ进程接收第二信息而不是第一信息。由此，电子设备300能够接收到更新后的定时提前量。
作为示例，通信单元301可以被配置为经由通过INT-RNTI加扰的DCI被告知：网络侧设备在用于初传的第一HARQ进程中传送的、承载第一信息的MAC CE所在的时频资源无效，从而电子设备300在接收到第二信息之后，不将第一信息和第二信息进行软合并。由此，电子设备300不会将经由初传接收到的第一信息与经由重传接收到的第二信息进行软合并，以保证电子设备300将与第二信息有关的更新后的定时提前量作为其用于上行传输的定时提前量。例如，上述电子设备300可以是不支持基于CBG的传输的物联网中的电子设备。
作为示例，通信单元301还可以被配置为将经由用于重传的第一HARQ进程接收的信息当中的除了第二信息之外的信息与经由用于初传的第一HARQ进程接收的对应信息进行软合并。由此，电子设备300可以对除了定时提前量之外的、经由初传接收到的时频资源与经由重传接收到的对应时频资源进行软合并，以提高接收的可靠性。
作为示例，通信单元301可以被配置为基于CBG来接收第二信息，以及从网络侧设备接收用于指示重传的下行链路控制信息DCI，其中，在DCI中，码块组缓存清理信息CBGFI被设置为指示用于重传的第一HARQ进程中传送的所有CBG均不与用于初传的第一HARQ进程中传送的对应CBG进行软合并的值。由此，电子设备300不会将第一信息和第二信息进行软合并，以保证电子设备300将与第二信息有关的更新后的定时提前量作为其用于上行传输的定时提前量。
作为示例，通信单元301可以被配置为基于CBG来接收第二信息，以及从网络侧设备接收用于指示重传的下行链路控制信息DCI，其中，在DCI中，用于指示重传的下行链路控制信息DCI中的码块组缓存清理信息CBGFI的比特数被扩展为与码块组传输信息CBGTI的比特数相同， 以及CBGFI中的、与CBGTI中指示包括第二信息的CGB的比特所对应的比特被设置为以下值：该值指示在用于重传的第一HARQ进程中传送的包括第二信息的CBG与在用于初传的第一HARQ进程中传送的对应CBG不进行软合并。由此，电子设备300不对经由用于重传的第一HARQ进程接收的包括第二信息的CBG与经由用于初传的第一HARQ进程接收的对应CBG进行软合并，以保证电子设备300将与第二信息有关的更新后的定时提前量作为其用于上行传输的定时提前量。
