具体实施方式
为了更好的理解本公开实施例公开的一种时间偏移量的确定方法，下面首先对本公开实施例适用的通信***进行描述。
请参见图1，图1为本公开实施例提供的一种通信***的架构示意图。该通信***可包括但不限于一个网络设备、一个终端设备和一个卫星，图1所示的设备数量和形态仅用于举例并不构成对本公开实施例的限定，实际应用中可以包括两个或两个以上的网络设备，两个或两个以上的终端设备。图1所示的通信***以包括一个网络设备11、一个终端设备12和一个卫星13为例。
需要说明的是，本公开实施例的技术方案可以应用于各种通信***。例如：长期演进(long term evolution，LTE)***、第五代(5th generation，5G)移动通信***、5G新空口(new radio，NR)***，或者其他未来的新型移动通信***等。本公开实施例中的网络设备11是网络侧的一种用于发射或接收信号的实体。例如，网络设备11可以为演进型基站(evolved NodeB，eNB)、传输点(transmission reception point，TRP)、NR***中的下一代基站(next generation NodeB，gNB)、其他未来移动通信***中的基站或无线保真(wireless fidelity，WiFi)***中的接入节点等。本公开的实施例对网络设备所采用的具体技术和具体设备形态不做限定。本公开实施例提供的网络设备可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构可以将网络设备，例如基站的协议层拆分开，部分协议层的功能放在 CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。本公开实施例提供的卫星，可以为低轨道卫星，或者，还可以为高轨道卫星，本公开对此不做限定。
本公开实施例中的终端设备12是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端设备(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本公开的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
可以理解的是，本公开实施例描述的通信***是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着***架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本公开所提供的时间偏移量的确定方法及其装置进行详细地介绍。
请参见图2，图2是本公开实施例提供的一种时间偏移量的确定方法的流程示意图,该方法由终端设备执行。如图2所示，该方法可以包括但不限于如下步骤：
步骤21，根据消息2 MSG2中无线网络临时标识TC-RNTI的取值，确定当前针对波束或者针对用户组的第一时间偏移量。
其中，消息2 MSG2是在随机接入过程中，网络设备向终端设备返回的响应消息。MSG2中可以包含无线网络临时标识(Temporary Cell-Radio Network Temporary Identifier，TC-RNTI)的取值、定时提前命令(Timing Advance Command,TA)、上行调度准许(Up-Link，UL Grant)等等，本公开对此不做限定。
可以理解的是，在卫星通信中，每个卫星可以提供多个服务波束，每个服务波束对应的传输时延也不尽相同。在卫星高速运动的过程中，由于每个服务波束的覆盖范围不同，每个小区可能同时包含多个服务波束，终端设备与网络设备之间可以通过一个或是多个服务波束进行信息传输。因此，需要确定当前用于传输信息的波束对应的第一时间偏移量。
或者，由于卫星通信的覆盖范围较大，同一波束覆盖范围内，不同终端设备之间对应的第一时间偏移量可能不同，因此，可以进一步确定不同用户组对 应的第一时间偏移量。
其中，用户组是针对用户的集合，网络设备可以根据需要，将用户进行划分，以确定不同的用户组。
可选的，第一时间偏移量Koffset可以为以下任一项：
上行传输与下行传输间的时间差值；
上行传输与下行传输间隔的预定义时间单元的数量。
其中，上行传输与下行传输间的时间差值可以为绝对的时间差值。比如，上行传输与下行传输间的时间差值可以为10ms、5ms等等，本公开对此不做限定。
可选的，预定义时间单元可以为时隙、微时隙等等，本公开对此不做限定。
可选的，第一时间偏移量可应用于多种信息传输中，比如：下行控制信息(Downlink Control Information，DCI)调度的物理上行控制信道(Physical Uplink Shared CHannel，PUSCH)传输；混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)反馈信息的传输；以及，媒体访问控制(Media Access Control，MAC)控制单元(Control Element，CE)的传输等等，本公开对此不做限定。
通过实施本公开实施例，终端设备根据消息2 MSG2中无线网络临时标识TC-RNTI的取值，确定当前针对波束或者针对用户组的第一时间偏移量。由此，终端设备可以根据TC-RNTI的取值确定针对波束或者用户组的第一时间偏移量，对终端设备与网络设备之间传输的数据进行补偿，从而解决了由于卫星高速移动导致的终端设备与网络设备间的定时关系调整不准确的问题，保证了数据交互的可靠性。
请参见图3，图3是本公开实施例提供的一种时间偏移量的确定方法的流程示意图,该方法由终端设备执行。如图3所示，该方法可以包括但不限于如下步骤：
步骤31，根据协议约定，确定TC-RNTI与第一时间偏移量的对应关系。
其中，TC-RNTI与第一时间偏移量的对应关系可以如表1所示。
表1
TC-RNTI的取值 第一时间偏移量
0001–0FFF Koffset 1
1001-1FFF Koffset 2
… …
FFF3–FFFD Koffset N
如表1所示，多个TC-RNTI的取值可以对应同一个第一时间偏移量。
需要说明的是，表1只是TC-RNTI与第一时间偏移量的对应关系的示意性说明，不能做为本公开中TC-RNTI与第一时间偏移量的对应关系的具体限定。
可以理解的是，表1中的每一个元素、每一条对应关系，都是独立存在的；这些元素、对应关系被示例性的列在同一张表格中，但是并不代表表格中的所有元素、对应关系必须根据表1中所示的同时存在。其中每一个元素的值和每一对应关系，是不依赖于表1中任何其他元素值或对应关系。因此本领域内技术人员可以理解，该表1中的每一个元素的取值、每一条对应关系，各种都是一个独立的实施例。
步骤32，根据***信息中指定信息域的取值，确定网络设备是否支持针对波束或者针对用户组的第一时间偏移量。
其中，***信息为网络设备向终端设备发送的信息。网络设备可以在***信息中向终端设备指示自己是否支持针对波束或者针对用户组的第一时间偏移量。
其中，指定信息域中包含的比特位的数量，可以根据需要设置。比如指定信息域中包含1个比特位，该比特位取值为“0”，可以表示网络设备不支持针对波束或者针对用户组的第一时间偏移量，取值为“1”可以表示网络设备支持针对波束或者针对用户组的第一时间偏移量。或者，指定信息域中包含2个比特位，该比特位取值为“00”，可以表示网络设备不支持针对波束及针对用户组的第一时间偏移量，取值为“01”可以表示网络设备支持针对波束的第一时间偏移量，取值为“10”可以表示网络设备支持针对用户组的第一时间偏移量，“11”可以表示网络设备支持针对波束及用户组的第一时间偏移量等等，本公开对此不做限定。
步骤33，在网络设备支持针对波束或者针对用户组的第一时间偏移量的情况下，根据TC-RNTI与第一时间偏移量的对应关系，确定与MSG2中的TC-RNTI的取值对应的第一时间偏移量。
可以理解的是，在网络设备支持针对波束或者针对用户组的第一时间偏移量的情况下，再根据MSG2中无线网络临时标识TC-RNTI的取值，确定当前针对波束或者针对用户组的第一时间偏移量。由此，终端设备无需每次接收到MSG2之后，均确定TC-RNTI的取值对应的第一时间偏移量，仅在网络设备支持针对波束或者针对用户组的第一时间偏移量的情况下，再去根据TC-RNTI与第一时间偏移量的对应关系，确定第一时间偏移量，节省了终端设备的开销，减少资源浪费。
通过实施本公开实施例，终端设备首先根据协议约定或是接收基站发送的信令，确定TC-RNTI与第一时间偏移量的对应关系，之后根据***信息中指定信息域的取值，确定网络设备是否支持针对波束或者针对用户组的第一时间偏移量，最后在网络设备支持针对波束或者针对用户组的第一时间偏移量的情况下，根据TC-RNTI与第一时间偏移量的对应关系，确定与MSG2中的TC-RNTI的取值对应的第一时间偏移量。由此，终端设备在网络设备支持针对波束或者针对用户组的第一时间偏移量的情况下，根据MSG2中的TC-RNTI的取值，确定第一时间偏移量，不仅解决了由于卫星的高速移动导致的终端设备与网络设 备之间的传输时延调整不准确的问题，保证了数据交互的可靠性，还节省了终端设备的开销，减少了资源浪费。
请参见图4，图4是本公开实施例提供的一种时间偏移量的确定方法的流程示意图,该方法由终端设备执行。如图4所示，该方法可以包括但不限于如下步骤：
步骤41，根据网络设备的指示，确定TC-RNTI与第一时间偏移量的对应关系。
步骤42，根据MSG2中预留的信息域的取值，确定网络设备是否支持针对波束或者针对用户组的第一时间偏移量。
其中，预留的信息域中包含的比特位的数量，可以根据需要设置。比如预留的信息域中包含1个比特位，该比特位取值为“0”，可以表示网络设备不支持针对波束或者针对用户组的第一时间偏移量，取值为“1”可以表示网络设备支持针对波束或者针对用户组的第一时间偏移量。或者，预留的信息域中包含2个比特位，该比特位取值为“00”，可以表示网络设备不支持针对波束及针对用户组的第一时间偏移量，取值为“01”可以表示网络设备支持针对波束的第一时间偏移量，取值为“10”可以表示网络设备支持针对用户组的第一时间偏移量，“11”可以表示网络设备支持针对波束及用户组的第一时间偏移量等等，本公开对此不做限定。
可选的，MSG2中预留的信息域可以在MSG2整个信息域预定义的位置上，比如在整个信息域的第一个信息比特位，以方便终端设备根据预留的信息域的取值，确定网络设备是否支持针对波束或者针对用户组的第一时间偏移量。本公开对此不做限定。
可以理解的是，网络设备直接利用在MSG2中预留的信息域，向终端设备传输自己是否支持针对波束或者针对用户组的第一时间偏移量，无需利用其他信息进行传输，减少了资源浪费。且终端设备只需在接收到MSG2之后，即可确定网络设备是否支持针对波束或者针对用户组的第一时间偏移量，并在确定网络设备支持针对波束或者针对用户组的第一时间偏移量之后，确定MSG2中的TC-RNTI的取值对应的第一时间偏移量，进一步节省了终端设备的开销。
步骤43，在网络设备支持针对波束或者针对用户组的第一时间偏移量的情况下，根据TC-RNTI与第一时间偏移量的对应关系，确定与MSG2中的TC-RNTI的取值对应的第一时间偏移量。
其中，步骤43的具体实现形式，可参照本公开中其他各实施例中的详细描述，此处不再详细赘述。
通过实施本公开实施例，终端设备首先根据网络设备的指示，确定TC-RNTI与第一时间偏移量的对应关系，之后根据MSG2中预留的信息域的取值，确定网络设备是否支持针对波束或者针对用户组的第一时间偏移量，最后在网络设备支持针对波束或者针对用户组的第一时间偏移量的情况下，根据 TC-RNTI与第一时间偏移量的对应关系，确定与MSG2中的TC-RNTI的取值对应的第一时间偏移量。由此，终端设备在网络设备支持针对波束或者针对用户组的第一时间偏移量的情况下，根据MSG2中的TC-RNTI的取值，确定第一时间偏移量，不仅解决了终端设备与网络设备之间的传输时延问题，保证了数据交互的可靠性，还节省了终端设备的开销，减少了资源浪费。
请参见图5，图5是本公开实施例提供的一种时间偏移量的确定方法的流程示意图,该方法由网络设备执行。如图5所示，该方法可以包括但不限于如下步骤：
步骤51，根据当前针对波束或者针对用户组的第一时间偏移量，确定消息2 MSG2中无线网络临时标识TC-RNTI的取值。
其中，消息2 MSG2是在随机接入过程中，网络设备向终端设备返回的响应消息。MSG2中可以包含无线网络临时标识(Temporary community-Radio Network Tempory Identity，TC-RNTI)的取值、定时提前命令(Timing Advance Command,TA)、上行调度准许(Up-Link，UL Grant)等等，本公开对此不做限定。
其中，用户组是针对用户的集合，网络设备可以根据需要，将用户进行划分，以确定不同的用户组。
可选的，第一时间偏移量Koffset可以为以下任一项：
上行传输与下行传输间的时间差值；
上行传输与下行传输间隔的预定义时间单元的数量。
其中，上行传输与下行传输间的时间差值可以为绝对的时间差值。比如，上行传输与下行传输间的时间差值可以为10ms、5ms等等，本公开对此不做限定。
可选的，预定义时间单元可以为时隙、微时隙等等，本公开对此不做限定。
可选的，第一时间偏移量可应用于多种信息传输中，比如：下行控制信息(Downlink Control Information，DCI)调度的物理上行控制信道(Physical Uplink Shared CHannel，PUSCH)传输；混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)反馈信息的传输；以及，媒体访问控制(Media Access Control，MAC)控制单元(Control Element，CE)的传输等等，本公开对此不做限定。
通过实施本公开实施例，网络设备根据当前针对波束或者针对用户组的第一时间偏移量，确定消息2 MSG2中无线网络临时标识TC-RNTI的取值。由此，网络设备可以根据当前针对波束或者针对用户组的第一时间偏移量，确定TC-RNTI的取值，以使终端设备可以根据MSG2中的TC-RNTI的取值，确定第一时间偏移量，对终端设备与网络设备之间传输的数据进行补偿，从而解决了由于卫星高速移动导致的终端设备与网络设备间的定时关系调整不准确的问题，保证了数据交互的可靠性。
请参见图6，图6是本公开实施例提供的一种时间偏移量的确定方法的流程示意图,该方法由网络设备执行。如图6所示，该方法可以包括但不限于如下步骤：
步骤61，向终端设备指示网络设备是否支持针对波束或者针对用户组的第一时间偏移量。
可选的，网络设备可以通过***信息中的指定信息域，向终端设备指示网络设备是否支持针对波束或者针对用户组的第一时间偏移量。
其中，指定信息域中包含的比特位的数量，可以根据需要设置。比如指定信息域中包含1个比特位，该比特位取值为“0”，可以表示网络设备不支持针对波束或者针对用户组的第一时间偏移量，取值为“1”可以表示网络设备支持针对波束或者针对用户组的第一时间偏移量。或者，指定信息域中包含2个比特位，该比特位取值为“00”，可以表示网络设备不支持针对波束及针对用户组的第一时间偏移量，取值为“01”可以表示网络设备支持针对波束的第一时间偏移量，取值为“10”可以表示网络设备支持针对用户组的第一时间偏移量，“11”可以表示网络设备支持针对波束及用户组的第一时间偏移量等等，本公开对此不做限定。
可选的，网络设备也可以通过MSG2中预留的信息域，向终端设备指示网络设备是否支持针对波束或者针对用户组的第一时间偏移量。
其中，预留的信息域中包含的比特位的数量，可以根据需要设置。比如预留的信息域中包含1个比特位，该比特位取值为“0”，可以表示网络设备不支持针对波束或者针对用户组的第一时间偏移量，取值为“1”可以表示网络设备支持针对波束或者针对用户组的第一时间偏移量。或者，预留的信息域中包含2个比特位，该比特位取值为“00”，可以表示网络设备不支持针对波束及针对用户组的第一时间偏移量，取值为“01”可以表示网络设备支持针对波束的第一时间偏移量，取值为“10”可以表示网络设备支持针对用户组的第一时间偏移量，“11”可以表示网络设备支持针对波束及用户组的第一时间偏移量等等，本公开对此不做限定。
步骤62，在支持针对波束或者针对用户组的第一时间偏移量的情况下，根据协议约定，确定TC-RNTI与第一时间偏移量的对应关系。
其中，TC-RNTI与第一时间偏移量的对应关系可以如表1所示。此处不再详细赘述。
步骤63，根据TC-RNTI与第一时间偏移量的对应关系，确定MSG2中与当前的第一时间偏移量对应的TC-RNTI的取值。
可以理解的是，网络设备仅在自己支持针对波束或者针对用户组的第一时间偏移量的情况下，根据协议约定，确定TC-RNTI与第一时间偏移量的对应关系，进而确定MSG2中与当前的第一时间偏移量对应的TC-RNTI的取值。由此，无需确定每个MSG2中第一时间偏移量对应的TC-RNTI的取值，节省了网络设 备的开销。
通过实施本公开实施例，网络设备首先向终端设备指示网络设备是否支持针对波束或者针对用户组的第一时间偏移量，之后在支持针对波束或者针对用户组的第一时间偏移量的情况下，根据协议约定，确定TC-RNTI与第一时间偏移量的对应关系，最后根据TC-RNTI与第一时间偏移量的对应关系，确定MSG2中与当前的第一时间偏移量对应的TC-RNTI的取值。由此，网络设备支持针对波束或者针对用户组的第一时间偏移量的情况下，根据第一时间偏移量，确定TC-RNTI的取值，以使终端设备可以根据MSG2中的TC-RNTI的取值，确定第一时间偏移量，不仅解决了由于卫星高速移动导致的终端设备与网络设备间的定时关系调整不准确的问题，保证了数据交互的可靠性，还节省了网络设备的开销，减少了资源浪费。
