Description

载波确定方法及相关装置、系统信息广播方法及相关装置 技术领域
本发明涉及通信技术领域，特别涉及载波确定方法及相关装置、系统信息广播方法及相关装置，具体涉及一种载波确定方法、一种载波确定装置、一种用户设备、一种系统信息广播方法、一种系统信息广播装置、一种网络设备以及一种存储介质。
背景技术
目前的陆地网物联网协议例如窄带物联网NB-IoT或者eMTC的随机接入过程如图1所示，由Msg1、Msg2、Msg3以及Msg4四个步骤组成。Msg1即用户设备UE向网络设备发送随机接入前导码，目前Msg1发送的重复次数最大为128，UE在发送Msg1之前会通过窄带参考信号NRS获取当前的小区信号质量例如RSRP(Reference Signal Receiving Power，参考信号接收功率)，然后根据测量得到的信号质量与网络配置的相关门限值进行比较，进而确定当前的覆盖等级。不同的覆盖等级对应不同的PRACH(Physical Random Access Channel，物理随机接入信道)资源(包括Msg1重复次数)，UE根据自己确定的覆盖等级确定发送Msg1的重复次数，并随机选择一个配置了相应PRACH资源的上行载波发送Msg1。若第一次发送Msg1失败，则UE会再升级覆盖等级(即增加Msg1的重复次数)重新尝试，直到成功接收Msg2或者尝试完覆盖等级对应的Msg1重复次数为止。
当网络设备接收到Msg1后，通过随机接入响应消息Msg2-RAR指示UE发送Msg3的资源以及相关的参数(包括子载波指示、Msg3重复次数、MCS(Modulation and Coding Scheme，调制与编码策略)指示等)。随机接入响应消息Msg2-RAR是由DCI(Downlink Control Information，下行控制信息)调度的，UE首先接收下行控制信息(即RA-RNTI加扰的DCI，用于指示Msg2-RAR的传输参数，包括接收资源位置、子载波指示、Msg3重复次数、MCS指示等)，然后再根据下行控制信息接收Msg2-RAR。
UE根据Msg2-RAR指示的Msg3的相关调度信息发送Msg3，UE发送完Msg3之后，使用Msg3中携带的唯一标识监听PDCCH，成功解码PDCCH后，根据PDCCH承载的DCI信息接收相应的Msg4。
在目前的陆地网物联网协议中，发送Msg1的载波确定机制为：UE在所驻留小区配置的多个配置了PRACH资源的上行载波中随机选择一个上行载波用于发送Msg1。但是在 NTN(Non Terrestrial Networks，非陆地网络)场景下，一个小区由多个波束beam组成，不同的波束对应不同的上行载波组。随着卫星的快速移动，UE需要频繁地进行波束切换，上述现有的发送Msg1的载波确定机制显然已经无法适应卫星物联网场景。
另外，在现有确定接收寻呼Paging载波的协议中，网络设备通过系统信息下发有关Paging的配置信息，包括Paging的周期、PO(Paging Occasion，寻呼时刻)对应的PDCCH重复次数、N以及Ns(其中，每个非连续接收DRX周期内包含N个寻呼帧PF，每个PF内包含Ns个PO)等参数，同时也会配置每个载波的Paging权重。这些参数是小区级别的，即小区内所有载波的Paging参数配置都是一样的。UE在Idle态的时候，根据UE_ID、参数N、参数Ns以及每个载波的权重可以确定在哪个载波上进行Paging的监听。
同样地，在卫星物联网场景中，随着卫星的快速移动，UE需要频繁地进行波束切换，上述现有的确定接收Paging载波的协议显然也已经无法适应卫星物联网场景。

下面通过实施例的方式进一步说明本发明，但并不因此将本发明限制在所述的实施例范围之中。
以下，对本发明实施例的示例性应用场景进行介绍。

实施例1
图3是本实施例提供的载波确定方法的流程示意图，该方法可以由载波确定装置执行，该装置可以通过软件和/或硬件的方式实现，该装置可以包括用户设备和网络设备的部分或全部。下面结合用户设备和网络设备为执行主体对载波确定方法进行说明。
如图3所示，本实施例提供的载波确定方法包括以下步骤S101～S104：
步骤S101、根据用户设备的位置信息和卫星星历信息确定所述用户设备当前所在的目 标波束。
步骤S101中，用户设备可以根据全球导航卫星系统GNSS获取自身的位置信息。卫星星历信息可以通过网络设备广播的系统信息接收，也可以预配置在用户设备中。其中，卫星星历信息可以包括卫星的轨道信息、卫星的运行速度以及每个小区的波束分布信息等。用户设备根据自身的位置信息以及卫星星历信息确定用户设备当前所在的目标波束，其中，所述目标波束即为当前覆盖用户设备的波束。
步骤S102、网络设备广播系统信息。其中，所述系统信息包括所述用户设备所在小区中与每个波束对应的多个载波的索引配置信息。本实施方式中，网络设备为用户设备所在小区中的每个波束配置了多个载波，且通过广播系统消息的方式将与每个波束对应的多个载波的索引配置信息下发。
步骤S103、用户设备接收网络设备广播的系统信息，根据所述系统信息确定与所述目标波束对应的多个载波的索引配置信息。用户设备根据接收的系统信息确定与目标波束对应的多个载波的索引。其中，与目标波束对应的载波可以为上行载波，也可以为下行载波。
步骤S104、用户设备在与所述目标波束对应的多个载波中确定用于传输目标消息的目标载波。
步骤S105、用户设备通过目标载波向网络设备传输目标消息。
可以理解地，在NB-IoT物联网协议中用户设备与网络设备之间的数据传输带宽是一个物理资源块(Physical Resource Block，PRB)，一个物理资源块也称作一个载波，但是在eMTC物联网协议中用户设备与网络设备之间的数据传输带宽为一个窄带。需要说明的是，若物联网协议为eMTC，则本发明实施例中的载波等同于窄带。
在可选的一种实施方式中，与每个波束对应的多个载波均为配置了物理随机接入信道资源即PRACH资源的上行载波，所述目标消息为随机接入消息。上述步骤S104具体包括：用户设备在与所述目标波束对应的多个配置了物理随机接入信道资源的上行载波中随机确定用于发送随机确定消息的目标上行载波。
本实施方式中，用户设备可以在随机接入过程中通过目标上行载波向网络设备发送随机接入消息，其中，所述随机接入消息可以包括随机前导码Msg1。网络设备为用户设备所在小区中的每个波束配置了多个上行载波，且为这些上行载波配置了物理随机接入信道资源，从而能够满足卫星物联网场景中用户设备频繁切换波束的需求，具体地，随着用户设备所在的波束发生变化，用户设备可以根据当前所在的波束确定发送随机接入消息的上行 载波，从而提高卫星通信的稳定性。
在可选的另一种实施方式中，与每个波束对应的多个载波均为下行寻呼载波，所述目标消息为寻呼消息，所述系统信息还包括所述用户设备所在小区中与每个波束对应的每个下行寻呼载波的寻呼权重，以及与每个波束对应的寻呼参数等配置信息。上述步骤S104具体包括：根据所述用户设备的标识信息、与所述目标波束对应的寻呼参数以及与所述目标波束对应的每个下行寻呼载波的寻呼权重，在与所述目标波束对应的多个下行寻呼载波中确定用于接收寻呼消息的目标下行寻呼载波。
其中，上述寻呼参数可以包括每个DRX周期内寻呼帧PF的数量及每个寻呼帧PF内寻呼时机PO的数量。
在一个具体的例子中，用户设备的标识信息为UE_ID，取值为IMSI mod 1024。其中，每个用户的IMSI(International Mobile Subscriber Identity，国际移动用户标识码)是唯一的。IMSI由数字0～9组成的一个序列表示，存储在SIM/USIM卡中。需要说明的是，如果用户设备并没有插入SIM/USIM卡，那么就不存在IMSI，此时UE_ID固定取0。
在具体实施的一个例子中，根据以下公式在与所述目标波束对应的多个下行寻呼载波中确定用于接收寻呼消息的目标下行寻呼载波：
(floor(UE_ID/(N*Ns))mod W)<(W(0)+W(1)+…+W(n))；
其中，floor为向下取整函数，mod为求余函数，W(i)为与目标波束对应的载波索引为i的下行寻呼载波的寻呼权重，其中i＝0,1,2,……,n，n小于等于与目标波束对应的下行寻呼载波的数量，W为与目标波束对应的所有下行寻呼载波的寻呼权重之和，N和Ns均为与目标波束对应的寻呼参数，其中N为每个DRX周期内寻呼帧PF的数量，Ns为每个寻呼帧PF内寻呼时机PO的数量。
需要说明的是，按照载波索引从0依次递增，直至首次满足上述公式，即满足公式的左边小于公式的右边，记录此时的载波索引X，然后确定载波索引为X的下行寻呼载波为目标下行寻呼载波。
本实施方式中，网络设备为用户设备所在小区中的每个波束单独配置寻呼权重和寻呼参数，从而能够满足卫星物联网场景中用户设备频繁切换波束的需求，具体地，随着用户设备所在的波束发生变化，用户设备可以根据当前所在的波束确定接收寻呼消息的下行寻呼载波，从而提高卫星通信的稳定性。
本实施例还提供一种载波确定装置40，如图4所示，包括目标波束确定模块41、第一 载波确定模块42以及第二载波确定模块43。
目标波束确定模块用于根据用户设备的位置信息和卫星星历信息确定所述用户设备当前所在的目标波束。
第一载波确定模块用于根据网络设备广播的系统信息确定与所述目标波束对应的多个载波；其中，所述系统信息包括所述用户设备所在小区中与每个波束对应的多个载波的索引配置信息。
第二载波确定模块用于在与所述目标波束对应的多个载波中确定用于传输目标消息的目标载波。
在可选的一种实施方式中，与每个波束对应的多个载波均为配置了物理随机接入信道资源的上行载波，所述目标消息为随机接入消息；所述第二载波确定模块具体用于：在与所述目标波束对应的多个配置了物理随机接入信道资源的上行载波中随机确定用于发送随机接入消息的目标上行载波。
在可选的另一种实施方式中，与每个波束对应的多个载波均为下行寻呼载波，所述目标消息为寻呼消息，所述系统信息还包括所述用户设备所在小区中与每个波束对应的每个下行寻呼载波的寻呼权重，以及与每个波束对应的寻呼参数等配置信息；
所述第二载波确定模块具体用于根据所述用户设备的标识信息、与所述目标波束对应的寻呼参数以及与所述目标波束对应的每个下行寻呼载波的寻呼权重，在与所述目标波束对应的多个下行寻呼载波中确定用于接收寻呼消息的目标下行寻呼载波。
本实施例还提供一种系统信息广播装置，所述系统信息广播装置用于广播系统信息，其中，所述系统信息包括所述系统信息包括用户设备所在小区中与每个波束对应的多个载波的索引配置信息，其中，所述用户设备为上述实施例中的用户设备。

需要说明的是，上述载波确定装置或者系统信息广播装置具体可以是单独的芯片、芯片模组或者终端，也可以是集成于终端内的芯片或者芯片模组。
