Description

随机接入方法和装置、配置指示方法和装置 技术领域
本公开涉及通信技术领域，具体而言，涉及随机接入方法、配置指示方法、随机接入装置、配置指示装置、电子设备和计算机可读存储介质。
背景技术
随着通信技术的发展，需要满足基站与地面上任意位置的终端，都能够进行通信，但是由于目前网络中的基站位于地面，设置基站存在较多限制，难以通过地面基站全面地覆盖地面，因此考虑结合卫星进行覆盖。
在地面网络中，基站可以通过向终端发送定时提前量(Timing Advance，简称TA)，使得终端发送的上行信号帧与基站发送的下行信号帧相对应。
但是在非地面网络(Non-Terrestrial Network，简称NTN)中结合卫星进行通信时，由于卫星在空中，并且是高速移动的，基站通过卫星与终端通信时，存在的时延就较大，而定时提前量是根据时延设置的，因此定时提前量也就较大，由此会引发一些问题。
发明内容
有鉴于此，本公开的实施例提出了随机接入方法、配置指示方法、随机接入装置、配置指示装置、电子设备和计算机可读存储介质，以解决相关技术中的技术问题。

以便在终端自主确定定时提前量的情况下，提高单位时间内随机接入的容量，降低调度时延。在非自主确定定时提前量的情况下，确保随机接入资源的间隔满足通信时延的误差。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
图1是根据本公开的实施例示出的一种随机接入方法的示意流程图。本实施例所示的方法可以适用于非地面网络中的终端，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等电子设备。所述终端可以作为用户设备与基站通信，其中，所述基站可以是非地面网络中位于地面的基站，也可以是非地面网络中位于空中的网络设备，例如卫星、空中平台等。以下主要在所述网络设备为卫星的情况下进行示例性说明。
如图1所示，所述随机接入方法可以包括以下步骤：
在步骤S101中，响应于所述终端自主确定定时提前量，基于第一随机接入配置信息发起随机接入，响应于所述终端非自主确定定时提前量，基于第二随机接入配置信息发起随机接入；
其中，所述第一随机接入配置信息和所述第二随机接入配置信息不同。
在非地面网络中，无论终端与位于地面的基站之间通信，还是与作为基站的卫星进行通信，都需要将通信信号发送至卫星。由于卫星位于空中，通信信号传输至卫星需要较长的时间，导致终端与基站的通信时延较大，最大甚至可以达到541.46ms。
为了补偿非地面网络中的通信时延，终端在通信过程中，可以基于定时提前量进行补偿，其中的补偿方式主要包括两种：
第一种方式是终端指自主确定定时提前量，适用于终端能够确定自身位置的情况。终端可以根据终端到卫星的距离计算需要补偿的时延，这种情况适用于卫星再生模式，也即卫星作为基站；或者根据终端到卫星的距离，以及卫星到基站的距离或者时延计算需要补偿的时延，这种情况适用于基站位于地面的情况。
终端确定的需要补偿的时延可以作为定时提前量，该定时提前量可以在随机接入过程中上报给基站，例如携带在随机接入过程中的Msg3或者MsgA中。终端与基站通信时，可以补偿全部的定时提前量，也可以先接收网络广播的公共定时提前量(可以称作common TA)，然后进行部分补偿，也即补偿全部的定时提前量与公共定时提前量的差值。
第二种方式是指终端非自主确定定时提前量，适用于终端不能确定自身位置的情况。终端可以接收网络广播的公共定时提前量，然后在与基站通信时，补偿该公共定时提前量，或者终端不补偿定时提前量，而由网络补偿公共定时提前量，例如由卫星补偿公共定时提前量。
例如卫星到地面参考点(可以是指卫星在地面投影的位置)的距离为d0，卫星与终端的距离为d1，卫星到基站的距离为d0_F，光速为c。那么在卫星再生模式下，公共定时提前量等于卫星到地面参考点的双向时延，具体等于2*d0/c；在终端与位于地面的基站通信时，公共定时提前量等于卫星到地面参考点的双向时延，加上卫星到地面基站的双向时延，具体等于2*(d0+d0_F)/c。
可见，终端基于上述两种方式补偿的时延有所不同。
在自主确定定时提前量的情况下，由于终端的位置可以确定，所以据此确定的定时提前量是相对准确的，进而补偿的时延也是相对准确的，一般可以保证实际存在的时延与补偿的时延误差在1ms以内。
而在非自主确定定时提前量的情况下，由于并不是根据终端的位置确定定时提前量，补偿是基于公共定时提前量进行的，并且公共定时提前量中并不包含卫星到终端的距离d1，只包含卫星到地面参考点的距离d0，所以实际的时延与补偿的时延误差较大，该误差与d1和d0的差值正相关，对于覆盖半径3500km的小区而言，该误差甚至可以达到20.6ms。
终端在随机接入过程中为了补偿时延，需要按照上述自主确定定时提前量的方式或者非自主确定提前量的方式进行补偿。也即在随机接入过程中，向基站发送信息(例如Msg1、Msg3、MsgA等)时，需要按照自主确定定时提前量的方式提全部的定时提前量，或者提前全部的定时提前量与公共定时提前量的差值；或者按照非自主确定提前量的方式，提前公共定时提前量，或者由网络补偿公共定时提前量。
基站为了确保能够区分同一个终端或不同终端在随时接入过程中发送的不同信息，为终端分配用于发送Msg1、Msg3、MsgA等信息的随机接入资源的间隔需要大于通信时延可能的最大误差，例如上述20.6ms。但是随机接入资源的间隔越大，随机接入资源的密度就越低，单位时间内随机接入的容量就越少，导致调度时延较大。
相关技术中，由于基站并不能确定终端是自主确定定时提前量，还是非自主确定定时提前量，为了确保终端与基站的通信同时适用于上述两种方式，基站会基于上述第二种方式为终端配置随机接入资源，终端在随机接入过程中也只基于这一种随机接入配置信息向基站发送信息，从而导致单位时间内随机接入的容量较少，调度时延较大。
根据本公开的实施例，基站可以针对终端自主确定定时提前量的情况，和非自 主确定定时提前量的情况，分别发送不同的随机接入配置信息，使得终端在自主确定定时提前量的情况下，能够基于第一随机接入配置信息发起随机接入，在非自主确定定时提前量的情况下，能够基于第二随机接入配置信息发起随机接入，并且第一随机接入配置信息和第二随机接入配置信息不同。
也即终端在自主确定定时提前量的情况下和在非自主确定定时提前量的情况下，在随机接入的过程中，能够基于不同的随机接入配置信息向终端发送随机接入信息，例如发送Msg1、Msg3、MsgA等信息，从而终端不必只根据一种随机接入配置信息向基站发送信息。
例如在自主确定定时提前量的情况下，由于通信时延可能的误差较小，第一随机接入配置信息对应的随机接入资源密度可以较大，以便提高单位时间内随机接入的容量，降低调度时延。而在非自主确定定时提前量的情况下，由于通信时延可能的误差较大，第二随机接入配置信息对应的随机接入资源密度可以较小，以便确保随机接入资源的间隔满足通信时延的误差。
需要说明的是，第一随机接入配置信息对应的随机接入资源和第二随机接入配置信息对应的随机接入资源之间的关系，并不局限于上述密度关系，可以根据需要进行灵活设置。
在一个实施例中，第一随机接入配置信息包括但不限于针对Msg1的配置、针对MsgA的配置、针对Msg3的配置。第二随机接入配置信息包括但不限于针对Msg1的配置、针对MsgA的配置、针对Msg3的配置。其中，Msg1是指四步随机接入过程中的第一条随机接入信息，Msg3是指四步随机接入过程中的第三条随机接入信息，MsgA是指两步随机接入过程中终端向基站发送的随机接入信息。
图2是根据本公开的实施例示出的另一种随机接入方法的示意流程图。如图2所示，所述方法还包括：
在步骤S102中，根据基站发送的广播信令和/或无线资源控制信令，确定在所述终端自主确定定时提前量时，基于第一随机接入配置信息发起随机接入；和/或根据基站发送的广播信令和/或无线资源控制信令，确定在所述终端非自主确定定时提前量，基于第二随机接入配置信息发起随机接入。
在一个实施例中，基站可以通过广播信令指示终端，在自主确定定时提前量时，基于第一随机接入配置信息发起随机接入，也可以通过无线资源控制(Radio Resource  Control，简称RRC)信令指示终端，在自主确定定时提前量时，基于第一随机接入配置信息发起随机接入。
在一个实施例中，基站可以通过广播信令指示终端，在自主确定定时提前量时，基于第二随机接入配置信息发起随机接入，也可以通过无线资源控制信令指示终端，在自主确定定时提前量时，基于第二随机接入配置信息发起随机接入。
可选地，所述第一随机接入配置信息用于指示第一随机接入时域资源，所述第二随机接入配置信息用于指示第二随机接入时域资源；
其中，所述第一随机接入时域资源与所述第二随机接入时域资源不同。
在一个实施例中，第一随机接入配置信息和第二随机接入配置信息不同，具体可以包括第一随机接入时域资源与第二随机接入时域资源不同。
可选地，所述第一随机接入时域资源与所述第二随机接入时域资源的密度不同。
在一个实施例中，第一随机接入时域资源与第二随机接入时域资源不同，具体可以体现在第一随机接入时域资源与所述第二随机接入时域资源的密度不同。
可选地，所述第一随机接入时域资源的密度大于所述第二随机接入时域资源的密度。
在一个实施例中，在自主确定定时提前量的情况下，由于通信时延可能的误差较小，第一随机接入配置信息对应的第一随机接入时域资源密度可以较大，以便提高单位时间内随机接入的容量，降低调度时延。而在非自主确定定时提前量的情况下，由于通信时延可能的误差较大，第二随机接入配置信息对应的第二随机接入时域资源密度可以较小，以便确保随机接入资源的间隔满足通信时延的误差。
可选地，所述第一随机接入时域资源的密度为所述第二随机接入示意资源的密度的第一倍数，其中，所述第一倍数大于1。
在一个实施例中，第一随机接入时域资源的密度可以为第二随机接入时域资源的密度的第一倍数，也即在第一随机接入时域资源的密度大于第二随机接入时域资源的密度的情况下，第一随机接入时域资源和第二随机接入时域资源可以不是散乱分布的，而是可以存在一定关系的。
据此，由于两个随机接入时域资源存在关系，因此终端可以基于其中一个随机 接入时域资源，确定另一个随机接入时域资源，有利于减少基站所需指示给终端的信息，从而减少对通信资源的占用。
在一个实施例中，终端可以根据基站发送信令中的prach-ConfigurationIndex确定第一随机接入配置信息和第二随机接入配置信息，而在第一随机接入时域资源的密度为所述第二随机接入示意资源的密度的第一倍数的情况下，第一随机接入配置信息和第二随机接入配置信息分别对应的prach-ConfigurationIndex可以是相同的，终端根据第一随机接入配置信息对应的prach-ConfigurationIndex可以直接确定第一随机接入时域资源，但是需要根据第一随机接入配置信息对应的prach-ConfigurationIndex以及基站指示的第一倍数确定第二随机接入时域资源。
图3是根据本公开的实施例示出的又一种随机接入方法的示意流程图。如图3所示，所述响应于所述终端非自主确定定时提前量，基于第二随机接入配置信息发起随机接入包括：

在步骤S1012中，响应于所述终端非自主确定定时提前量，在所述第二随机接入时域资源的时域位置发起随机接入。
在一个实施例中，在第一随机接入时域资源的密度为第二随机接入时域资源的密度的第一倍数的情况下，基站可以向终端指示第一随机接入时域资源的时域位置，以及第一倍数和偏移量，而无需指示第二随机接入时域资源的时域位置，终端可以根据第一随机接入时域资源的时域位置以及第一倍数和偏移量确定第二随机接入时域资源的时域位置，进而在终端非自主确定定时提前量的情况下，在第二随机接入时域资源的时域位置发起随机接入。
例如第一随机接入时域资源配置在信号帧0、1、2、3、4、5、6、7、8、9上，第一随机接入时域资源的密度是第二随机接入时域资源的密度的2倍，也即第一倍数m＝2，基站可以将数值2和偏移量offset发送给终端，或者终端可以预存所述偏移量。
例如偏移量offset为1，那么第二随机接入时域资源就是第一随机接入时域资源所在信号帧的一半，也即0、2、4、6、8，再偏移1个信号帧，也即1、3、5、6、7。
可选地，所述偏移量为从所述基站接收到的或者预先存储的。
可选地，所述第一随机接入配置信息用于指示第一随机接入频域资源，所述第 二随机接入配置信息用于指示第二随机接入频域资源；
其中，所述第一随机接入频域资源与所述第二随机接入频域资源不同。
在一个实施例中，第一随机接入配置信息和第二随机接入配置信息不同，具体可以包括第一随机接入配置信息所指示的第一随机接入频域资源，与第二随机接入配置信息所指示的第二随机接入频域资源不同。
可选地，所述第一随机接入配置信息用于指示所述第一随机接入频域资源的第一频域位置，所述第二随机接入配置信息用于指示所述第二随机接入频域资源的第二频域位置；或者
所述第一随机接入配置信息用于指示所述第一随机接入频域资源的第一频域位置，所述第二随机接入配置信息用于指示所述第二随机接入频域资源相对于所述第一频域位置的第一偏移量；或者
所述第二随机接入配置信息用于指示第二随机接入频域资源的第二频域位置，所述第一随机接入配置信息用于指示第一随机接入频域资源相对于所述第二频域位置的第二偏移量。
在一个实施例中，可以通过第一随机接入配置信息直接指示第一随机接入频域资源的第一频域位置，以及第二随机接入配置信息直接指示第二随机接入频域资源的第二频域位置。
也可以通过第一随机接入配置信息指示第一随机接入频域资源的第一频域位置，以及通过第二随机接入配置信息指示第二随机接入频域资源相对于第一频域位置的第一偏移量，从而使得终端可以根据第一频域位置和第一偏移量确定第二随机接入频域资源的第二频域位置；
还可以通过第二随机接入配置信息指示第二随机接入频域资源的第二频域位置，以及通过第一随机接入配置信息指示第一随机接入频域资源相对于第二频域位置的第二偏移量，从而使得终端可以根据第二频域位置和第二偏移量确定第一随机接入频域资源的第一频域位置。
可选地，所述第一随机接入配置信息用于指示第一随机接入前导码，所述第二随机接入配置信息用于指示第二随机接入前导码；
其中，所述第一随机接入前导码与所述第二随机接入前导码不同。
在一个实施例中，第一随机接入配置信息和第二随机接入配置信息不同，具体可以包括第一随机接入配置信息所指示的第一随机接入前导码，与第二随机接入配置信息所指示的第二随机接入前导码不同。
图4是根据本公开的实施例示出的一种配置指示方法的示意流程图。本实施例所示的方法可以适用于非地面网络中的基站，所述基站可以是非地面网络中位于地面的基站，也可以是非地面网络中位于空中的网络设备，例如卫星、空中平台等。所述基站可以与作为用户设备的终端进行通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等电子设备。以下主要在所述网络设备为卫星的情况下进行示例性说明。
如图4所示，所述配置指示方法可以包括以下步骤：
在步骤S201中，向终端发送包含第一随机接入配置信息和第二随机接入配置信息的指示信息；
其中，所述指示信息用于指示所述终端，在所述终端自主确定定时提前量时，基于所述第一随机接入配置信息发起随机接入，在所述终端非自主确定定时提前量时，基于所述第二随机接入配置信息发起随机接入，且所述第一随机接入配置信息和所述第二随机接入配置信息不同。
相关技术中，由于基站并不能确定终端是自主确定定时提前量，还是非自主确定定时提前量，为了确保终端与基站的通信同时适用于上述两种方式，基站会基于上述第二种方式为终端配置随机接入资源，终端在随机接入过程中也只基于这一种随机接入配置信息向基站发送信息，从而导致单位时间内随机接入的容量较少，调度时延较大。
根据本公开的实施例，基站可以针对终端自主确定定时提前量的情况，和非自主确定定时提前量，分别发送不同的随机接入配置信息，使得终端在自主确定定时提前量的情况下，能够基于第一随机接入配置信息发起随机接入，在非自主确定定时提前量的情况下，能够基于第二随机接入配置信息发起随机接入，并且第一随机接入配置信息和第二随机接入配置信息不同。
也即终端在自主确定定时提前量的情况下和在非自主确定定时提前量的情况下，在随机接入的过程中，能够基于不同的随机接入配置信息向终端发送随机接入信息，例如发送Msg1、Msg3、MsgA等信息，从而终端不必只根据一种随机接入配置信 息向基站发送信息。
例如在自主确定定时提前量的情况下，由于通信时延可能的误差较小，第一随机接入配置信息对应的随机接入资源密度可以较大，以便提高单位时间内随机接入的容量，降低调度时延。而在非自主确定定时提前量的情况下，由于通信时延可能的误差较大，第二随机接入配置信息对应的随机接入资源密度可以较小，以便确保随机接入资源的间隔满足通信时延的误差。
可选地，所述指示信息携带在广播信令和/或无线资源控制信令中。

可选地，所述第一随机接入时域资源的密度大于所述第二随机接入时域资源的密度。
在一个实施例中，在自主确定定时提前量的情况下，由于通信时延可能的误差较小，第一随机接入配置信息对应的第一随机接入时域资源密度可以较大，以便提高单位时间内随机接入的容量，降低调度时延。而在非自主确定定时提前量的情况下，由于通信时延可能的误差较大，第二随机接入配置信息对应的第二随机接入时域资源 密度可以较小，以便确保随机接入资源的间隔满足通信时延的误差。
可选地，所述第一随机接入时域资源的密度为所述第二随机接入示意资源的密度的第一倍数，其中，所述第一倍数大于1。
在一个实施例中，第一随机接入时域资源的密度可以为第二随机接入时域资源的密度的第一倍数，也即在第一随机接入时域资源的密度大于第二随机接入时域资源的密度的情况下，第一随机接入时域资源和第二随机接入时域资源可以不是散乱分布的，而是可以存在一定关系的。
据此，由于两个随机接入时域资源存在关系，因此终端可以基于其中一个随机接入时域资源，确定另一个随机接入时域资源，有利于减少基站所需指示给终端的信息，从而减少对通信资源的占用。
在一个实施例中，基站可以通过信令中的prach-ConfigurationIndex指示第一随机接入配置信息和第二随机接入配置信息，而在第一随机接入时域资源的密度为所述第二随机接入示意资源的密度的第一倍数的情况下，第一随机接入配置信息和第二随机接入配置信息分别对应的prach-ConfigurationIndex可以是相同的，终端根据第一随机接入配置信息对应的prach-ConfigurationIndex可以直接确定第一随机接入时域资源，但是需要根据第一随机接入配置信息对应的prach-ConfigurationIndex以及基站指示的第一倍数确定第二随机接入时域资源。
可选地，所述指示信息还用于指示所述终端，根据所述第一随机接入时域资源的时域位置以及所述第一倍数和偏移量确定所述第二随机接入时域资源的时域位置。

例如第一随机接入时域资源配置在信号帧0、1、2、3、4、5、6、7、8、9上，第一随机接入时域资源的密度是第二随机接入时域资源的密度的2倍，也即第一倍数m＝2，基站可以将数值2和偏移量offset发送给终端，或者终端可以预存所述偏移量。
例如偏移量offset为1，那么第二随机接入时域资源就是第一随机接入时域资 源所在信号帧的一半，也即0、2、4、6、8，再偏移1个信号帧，也即1、3、5、6、7。
