具体实施方式
为了更好的理解本公开实施例公开的一种物理随机接入信道PRACH的传输方法，下面首先对本公开实施例适用的通信系统进行描述。
请参见图1，图1为本公开实施例提供的一种通信系统1的架构示意图。该通信系统可包括但不限于一个网络侧设备和一个终端设备，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侧设备，两个或两个以上的终端设备。图1所示的通信系统1以包括一个网络侧设备11和一个终端设备12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系统。例如：长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)移动通信系统、5G新空口(new radio，NR)系统，或者其他未来的新型移动通信系统等。
本公开实施例中的网络侧设备11是网络侧的一种用于发射或接收信号的实体。例如，网络侧设备101可以为演进型基站(evolved NodeB，eNB)、传输点(transmission reception point，TRP)、NR系统中的下一代基站(next generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本公开的实施例对网络侧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侧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的结构可以将网络侧设备，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。

下面结合附图对本公开所提供的一种位置信息更新方法和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PRACH的传输方法的流程图。
如图2所示，该方法由终端设备执行，该方法可以包括但不限于如下步骤：
S21：确定PRACH的重复次数。
S22：根据重复次数进行PRACH的传输。
可以理解的是，终端设备发送PRACH时，终端设备未与网络侧设备建立RRC(Radio Resource Control，无线资源控制)连接，此时，网络侧设备将无法通过RRC或终端设备特定的PDCCH(Physical Downlink Control Channel，物理下行控制信道)进行重复次数的指示。
在一些实施例中，PRACH的重复次数由协议约定。
本公开实施例中，终端设备能够根据协议约定，确定PRACH的重复次数，由此，根据确定的PRACH的重复次数，进行PRACH的传输。
示例性实施例中，协议约定PRACH的重复次数为固定值，例如固定值为8，终端设备能够根据协议约定，确定PRACH的重复次数为8次，由此，根据确定的PRACH的重复次数为8次，可以进行8次PRACH的重复传输。
基于此，本公开实施例中，终端设备确定PRACH的重复次数，其中，PRACH的重复次数由协议约定，并根据确定的PRACH的重复次数，进行PRACH的传输。由此，终端设备确定PRACH传输的重复次数，实现重复次数的PRACH传输，以实现PRACH覆盖增强。
请参见图3，图3是本公开实施例提供的另一种PRACH的传输方法的流程图。
如图3所示，该方法由终端设备执行，该方法可以包括但不限于如下步骤：

S32：根据重复次数进行PRACH的传输。
本公开实施例中，终端设备能够根据网络侧设备的指示信息，确定PRACH的重复次数，由此，根 据确定的PRACH的重复次数，进行PRACH的传输。
在一些实施例中，网络侧设备的指示信息指示PRACH的重复次数为预设值。
示例性实施例中，网络侧设备的指示信息指示PRACH的重复次数为预设值8，终端设备能够根据网络侧设备的指示信息，确定PRACH的重复次数为8次，由此，根据确定的PRACH的重复次数为8次，可以进行8次PRACH的重复传输。
在另一些实施例中，终端设备确定侯选值集合；根据网络侧设备的指示信息从侯选值集合之中选择重复次数。
示例性实施例中，终端设备确定候选值集合为{2,4,8}，根据网络侧设备的指示信息从侯选值集合之中选择重复次数4，终端设备能够根据网络侧设备的指示信息，确定PRACH的重复次数为4次，由此，根据确定的PRACH的重复次数为4次，可以进行4次PRACH的重复传输。
在又一些实施例中，终端设备获取随机接入配置表，其中，随机接入配置表之中包括重复次数信息；根据指示信息指示的索引值从随机接入配置表之中获取重复次数。

在一些实施例中，指示信息由物理广播信息MIB携带、或由系统信息块SIB1携带、或由物理广播信道PBCH的额外载荷携带。
在一些实施例中，指示信息由MIB或SIB1的已有比特域进行携带，或者由MIB或SIB1的扩展比特域进行携带。
本公开实施例中，网络设备的指示信息可以由PBCH(Physical Broadcast Channe，物理广播信道)承载的MIB(Master Information Block，主信息块)携带，其中，指示信息由MIB的已有比特域进行携带或者由MIB的扩展比特域进行携带。
本公开实施例中，网络设备的指示信息可以由PBCH的额外载荷携带。
本公开实施例中，网络设备的指示信息可以由系统信息块SIB1(system information block，系统信息块1)携带，其中，指示信息由系统信息块SIB1的已有比特域进行携带或者由系统信息块SIB1的扩展比特域进行携带。
基于此，本公开实施例中，终端设备确定PRACH的重复次数，其中，PRACH的重复次数由网络侧设备的指示信息进行确定，并根据确定的PRACH的重复次数，进行PRACH的传输。由此，终端设备确定PRACH传输的重复次数，实现重复次数的PRACH传输，以实现PRACH覆盖增强。
请参见图4，图4是本公开实施例提供的又一种PRACH的传输方法的流程图。
如图4所示，该方法由终端设备执行，该方法可以包括但不限于如下步骤：
S41：确定PRACH的重复次数；其中，获取终端设备选择的同步信号块SSB信息；其中，每个SSB信息对应有重复次数信息；获取选择的SSB信息所对应的重复次数信息，并作为PRACH的重复次数。
S42：根据重复次数进行PRACH的传输。
本公开实施例中，终端设备能够根据选择的SSB(Synchronous Signal Block，同步信号块)信息，获取选择的SSB信息所对应的重复次数信息，并作为PRACH的重复次数，确定PRACH的重复次数， 由此，根据确定的PRACH的重复次数，进行PRACH的传输。终端设备会选择一个信道质量较强的最佳SSB，具体如何选择可以是现有的方法，所以本公开实施例中仅限定到重复次数和SSB信息绑定即可。
本公开实施例中，PRACH的重复次数可以与SSB波束进行绑定，每个SSB波束对应有重复次数信息，在终端设备选择下行SSB波束的情况下，能够根据选择的SSB波束对应的重复次数信息，隐式获得PRACH的重复次数。
基于此，本公开实施例中，终端设备确定PRACH的重复次数，其中，获取终端设备选择的同步块SSB信息；其中，每个SSB信息对应有重复次数信息；获取选择的SSB信息所对应的重复次数信息，并作为PRACH的重复次数，并根据确定的PRACH的重复次数，进行PRACH的传输。由此，终端设备确定PRACH传输的重复次数，实现重复次数的PRACH传输，以实现PRACH覆盖增强。
请参见图5，图5是本公开实施例提供的又一种PRACH的传输方法的流程图。
如图5所示，该方法由终端设备执行，该方法可以包括但不限于如下步骤：
S51：确定PRACH的重复次数；其中，获取终端设备的前导码Preamble；其中，每个Preamble对应有重复次数信息；获取Preamble所对应的重复次数信息，并作为PRACH的重复次数。
S52：根据重复次数进行PRACH的传输。
本公开实施例中，终端设备能够根据选择的前导码Preamble，获取选择的Preamble所对应的重复次数信息，并作为PRACH的重复次数，确定PRACH的重复次数，由此，根据确定的PRACH的重复次数，进行PRACH的传输。
本公开实施例中，PRACH的重复次数可以与PRACH Preamble进行绑定，对Preamble进行分组，某一组的Preamble对应一个固定次数的重复次数，在终端设备选择Preamble的情况下，能够根据选择的Preamble对应的重复次数信息，隐式获得PRACH的重复次数。
基于此，本公开实施例中，终端设备确定PRACH的重复次数，其中，获取终端设备的前导码Preamble；其中，每个Preamble对应有重复次数信息；获取Preamble所对应的重复次数信息，并作为PRACH的重复次数，并根据确定的PRACH的重复次数，进行PRACH的传输。由此，终端设备确定PRACH传输的重复次数，实现重复次数的PRACH传输，以实现PRACH覆盖增强。

如图6所示，该方法由终端设备执行，该方法可以包括但不限于如下步骤：

本公开实施例中，PRACH的重复次数可以与RO进行绑定，某一个RO或多个RO对应一个固定次数的重复次数，在终端设备选择RO的情况下，能够根据选择的RO对应的重复次数信息，隐式获得PRACH的重复次数。
基于此，本公开实施例中，终端设备确定PRACH的重复次数，其中，获取终端设备的随机接入时机RO；其中，每个RO对应有重复次数信息；获取RO所对应的重复次数信息，并作为PRACH的重复次数，并根据确定的PRACH的重复次数，进行PRACH的传输。由此，终端设备确定PRACH传输的重复次数，实现重复次数的PRACH传输，以实现PRACH覆盖增强。
请参见图7，图7是本公开实施例提供的又一种PRACH的传输方法的流程图。
如图7所示，该方法由网络侧设备执行，该方法可以包括但不限于如下步骤：
S71：指示终端设备的PRACH的重复次数，并接收终端设备发送的重复次数的PRACH传输。
可以理解的是，终端设备发送PRACH时，终端设备未与网络侧设备建立RRC(Radio Resource Control，无线资源控制)连接，此时，网络侧设备将无法通过RRC或终端设备特定的PDCCH(Physical Downlink Control Channel，物理下行控制信道)进行重复次数的指示。
通过实施本公开实施例，确定终端设备的PRACH的重复次数，从而，终端设备能够根据确定的PRACH的重复次数，进行PRACH的传输，以实现PRACH覆盖增强。
