图3为本公开实施例中电子设备的结构示意图。
具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，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作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。
针对卫星通信系统，不同的终端类型在能力上有着较大的差别，从而导致系统设计上需要针对不同终端有着不同的考虑，进而引入系统设计的复杂性。针对基于地面5G标准来设计的卫星通信系统，现有的终端能力中反映了最大速率、信道带宽和发送功率等信息，但是缺乏与卫星通信特征相关的信息，例如终端天线类型、终端应用场景、终端可视范围、终端移动速度、终端的发射天线等效口径、终端的接收天线等效口径、终端发送的最大EIRP、终端接收的G/T、终端的最大调度带宽、终端的最小接入带宽，等等。由于卫星通信特征相关的信息能够反映终端的能力，这些信息的缺乏会给系统设计带来困难。例如，终端天线类型不同，意味着系统采取的测量方法不同，使用相控阵天线的终端能够支持跨星测量，而使用单抛物面天线的终端不支持跨星测量，系统可以依据天线类型的不同来选择不同的终端测量方法；终端应用场景不同，意味着终端能抵抗的最大多普勒频偏不同，通常机载终端相对于车载终端具有更大的抗多普勒频偏能力，系统可以依据终端的应用场景来选择不同的随机接入信道参数等等。
基于此，本公开提出卫星通信系统设计需要的终端能力，即终端类型参数，使得系统设计能够兼容多样的终端类型，并能够自适应地配置相关的参数，以降低系统设计的复杂度。
下面对本公开进行具体说明。
如图1所示，为本公开实施例中系统设计方法的步骤流程图，该方法包括如下步骤：
步骤101：确定终端类型参数。
在本步骤中，具体的，由于终端类型能够反映卫星终端的主要特征，因此可以将终端类型参数作为一种新增的终端能力参数，使得卫星通信系统能够依据该终端类型参数进行针对性的系统设计，从而使得系统设计更为简单高效。
此外，具体的，终端类型参数能够反映终端之间的差异，此时该终端类型参数包括下述因素项中的至少一个：
终端天线类型、终端应用场景、终端可视范围、终端通信速率、终端移动速度、终端的发射天线等效口径、终端的接收天线等效口径、终端发送的最大等效全向辐射功率(简称EIRP)、终端接收的等效温度增益系数(简称G/T)、终端支持的最高信噪比、终端的最大调度带宽以及终端的最小接入带宽。
这样，通过将上述中的至少一个因素项确定为终端类型参数，基于该些因素项能够反映卫星终端的主要特征，从而使得将该些终端类型参数作为卫星通信系统的系统设计输入时，使得系统设计更加简单高效。
步骤102：基于终端类型参数，对卫星通信系统进行系统设计。
在本步骤中，具体的，在确定终端类型参数之后，基于确定的终端类型参数对卫星通信系统进行系统设计。
此时，基于所确定的终端类型参数对卫星通信系统进行系统设计，基于上述的终端类型参数与卫星通信特征相关，能够反映终端的能力，从而使得卫星通信系统在依据该些终端类型参数进行系统设计时，能够使得系统设计更加简单高效，避免了现有的终端能力中缺乏本公开中的终端类型参数时所导致的系统设计困难的问题。
在此需要说明的是，在上述的因素项中，若其中的第一因素项不能依据其他因素项得到，即不能依据其他因素项推导得出，则可以将该第一因素项作为所确定的终端类型参数，即该因素项为所确定的终端类型参数的必选项；此外，若其中的第二因素项能依据其他因素项得到，即能够依据其他因素项推导得到，则可以将该第二因素项作为所确定的终端类型参数的可选项，即所确定的终端类型参数可以不包括该第二因素项。
例如，本实施例可以将终端天线类型、终端应用场景、终端可视范围 作为终端类型参数的必选项，即终端类型参数至少包括终端天线类型、终端应用场景和终端可视范围。
此外，终端通信速率、终端移动速度、终端的发射天线等效口径、终端的接收天线等效口径、终端发送的最大EIRP、终端接收的G/T、终端支持的最高信噪比、终端的最大调度带宽以及终端的最小接入带宽，即可以作为终端类型参数的必选项，也可以作为终端类型参数的可选项，在此不进行具体限定。
此外，进一步地，本实施例在确定终端类型参数之后，可以通过广播信道、控制信道或业务信道，将该终端类型参数通知给终端和网络侧，从而使得终端侧和网络侧均能够获得统一的终端类型参数。
另外，进一步地，本实施例中在基于终端类型参数，对卫星通信系统进行系统设计时，可以包括如下设计方式中的至少一种：
其一，当终端类型参数中包括终端天线类型时，基于终端天线类型，确定终端是否支持跨星测量。
具体的，在终端类型参数中包括终端天线类型，使得在测量过程中，能够基于该终端天线类型，确定终端是否支持跨星测量，实现了对卫星通信系统中测量过程的参数设计。
其二，当终端类型参数中包括终端应用场景或终端移动速度时，基于终端应用场景或终端移动速度，确定是否启动混合自动重传请求(简称HARQ)。
具体的，在终端类型参数中包括终端应用场景或终端移动速度，使得在HARQ过程中，能够依据该终端应用场景或终端移动速度选择启动或者关闭HARQ，实现了对卫星通信系统中HARQ过程的参数设计。
其三，当终端类型参数中包括终端可视范围时，基于终端可视范围，确定终端的搜星范围和跟星范围。
具体的，在终端类型参数中包括终端可视范围，使得能够基于该终端可视范围，确定卫星通信系统的搜星范围和跟星范围，实现了对卫星通信系统中小区初搜过程及正常通信过程的参数设计。
其四，当终端类型参数中包括终端通信速率、终端的最大调度带宽或终端的最小接入带宽时，基于终端通信速率、终端的最大调度带宽或终端 的最小接入带宽，确定随机接入信道的前导码长度和子载波间隔。
具体的，在终端类型参数中包括终端通信速率、终端的最大调度带宽或终端的最小接入带宽，使得能够基于该终端通信速率、终端的最大调度带宽或终端的最小接入带宽，确定卫星通信系统的随机接入信道的前导码长度和子载波间隔，实现了对卫星通信系统中接入过程的参数设计。
这样，通过确定与终端特征相关的终端类型参数，使得能基于该些终端类型参数，对卫星通信系统的小区初搜过程、接入过程、测量过程和HARQ过程等系统参数进行设计，实现了系统设计的简单高效性。
下面通过具体举例对本实施例进行说明。

基于上述的描述，该终端类型参数在标准规范中可表达如下：
Figure PCTCN2020112575-appb-000001
当然，上述终端类型参数可以通过广播信道、控制信道或业务信道发送给终端和网络侧。
此时，基于该终端类型参数，网络侧和终端侧能够以此为输入进行系统设计。
例如，示例1，若终端类型参数中包括终端天线类型，则可以基于该终端天线类型设计终端测量方式。具体为：
若终端天线类型为相控阵天线，则确定终端支持跨星的波束测量；
若终端天线类型为双抛物面天线，则确定终端支持跨星的波束测量，且不同天线进行不同星的波束的测量；
若终端天线类型为单抛物面天线，则确定终端不支持跨星的波束测量。
再例如，示例2，若终端类型参数中包括终端应用场景或终端移动速度，则可以基于该终端类型参数判断HARQ功能的使用，具体描述如下：
若终端应用场景为机载、火车载、汽车载或终端支持的最高移动速度 大于或等于120km/h，则关闭HARQ功能；
若终端应用场景为船载、便携或终端支持的最高移动速度大于0且小于120km/h，则开启HARQ功能但为HARQ设置较少的进程；
若终端应用场景为固定或终端支持的最高移动速度等于0km/h，则开启HARQ功能但为HARQ设置较大的进程。
再例如，示例3，若终端类型参数中包括终端应用场景，则可以基于终端类型来判断终端能支持的最高移动速度，从而获得终端要抵抗的最大残留多普勒频偏，并以此选择合适的物理随机接入信道(简称PRACH)设计参数。具体描述如下：
若终端应用场景为机载，则终端支持的最高移动速度为1000km/h，终端要抵抗的最大残留多普勒频偏约30KHz，建议PRACH信道的子载波间隔不小于60KHz；
若终端应用场景为火车载，则终端支持的最高移动速度为350km/h，终端要抵抗的最大残留多普勒频偏约10KHz，建议PRACH信道的子载波间隔不小于30KHz；
若终端应用场景为汽车载，则终端支持的最高移动速度为120km/h，终端要抵抗的最大残留多普勒频偏约3KHz，建议PRACH信道的子载波间隔不小于15KHz；
若终端应用场景为船载，则终端支持的最高移动速度为60km/h，终端要抵抗的最大残留多普勒频偏约1.5KHz，建议PRACH信道的子载波间隔不小于10KHz；

若终端应用场景为固定位置，则终端支持的最高移动速度为0km/h，终端要抵抗的最大残留多普勒频偏约1KHz，建议PRACH信道的子载波间隔不小于5KHz。
再例如，示例4，若终端类型参数中包括终端可视范围，则可以基于该终端类型参数判断终端搜星范围和跟星范围，具体描述如下：
若终端可视范围为大角度，则表示终端工作在低纬度的偏置覆盖，搜 星和跟星中可以避开中心法向角度区域；
若终端可视范围为小角度，则表示终端工作在中高纬度的常规覆盖，搜星和跟星中直接全范围扫描。
再例如，示例5，若终端类型参数中包括终端通信速率或终端的最大调度带宽或终端的最小接入带宽，则可以基于该终端类型参数判断终端的随机接入信道的前导码长度和子载波间隔，具体描述如下：
若终端通信速率不小于75Mbps或终端的最大调度带宽不小于50MHz或终端的最小接入带宽不小于30MHz，则随机接入信道选择839*30KHz或者139*120KHz，即前导码长度为839、子载波间隔为30KHz或者前导码长度为139、子载波间隔为120KHz；
若终端通信速率小于75Mbps但大于等于20Mbps，或终端的最大调度带宽小于50MHz但大于等于20MHz，或终端的最小接入带宽小于30MHz但大于等于10MHz，则随机接入信道选择839*10KHz或者139*60KHz，即前导码长度为839、子载波间隔为10KHz或者前导码长度为139、子载波间隔为60KHz；
若终端通信速率小于20Mbps或终端的最大调度带宽小于20MHz或终端的最小接入带宽小于10MHz，则随机接入信道选择839*5KHz或者139*30KHz，即前导码长度为839、子载波间隔为5KHz或者前导码长度为139、子载波间隔为30KHz。
再例如，示例6，若终端类型参数中包括EIRP，则可以基于该终端类型参数来计算终端支持的最高信噪比、终端通信速率以及终端的最大调度带宽等，具体描述如下：
终端支持的最高信噪比与EIRP和G/T相关，则根据链路预算进行确定；
终端通信速率与系统单载波带宽BW total和最高信噪比SNR UE,max有关，则通信速率＝BW total*η UE,max，其中η UE,max由最高信噪比SNR UE,max决定，此时可以参照系统定义的调制与编码策略(简称MCS)表格；
终端的最大调度带宽BW UE,max与系统单载波带宽BW total、系统能支持的最大频谱效率η max以及由最高信噪比SNR UE,max决定的η UE,max相关，BW UE,max＝BW total*η UE,max/η max，其中η max为系统定义的MCS最大等级。
这样，本实施例提供的系统参数设计方法，通过确定终端类型参数，并基于终端类型参数对卫星通信系统进行针对性的系统设计，此时基于终端类型参数所包括的因素项中的终端天线类型、终端应用场景、终端可视范围、终端通信速率、终端移动速度、终端的发射天线等效口径、终端的接收天线等效口径、终端发送的最大EIRP、终端接收的G/T、终端支持的最高信噪比、终端的最大调度带宽、终端的最小接入带宽，均与卫星通信特征相关，能够反映终端的能力，从而使得卫星通信系统在依据该些终端类型参数进行系统设计时，能够使得系统设计更加简单高效，避免了现有的终端能力中缺乏本公开中的终端类型参数时所导致的系统设计困难的问题。
