为了便于理解，首先介绍本申请涉及的术语。
1、波束互易性(beam correspondence)
终端设备可以根据下行接收波束来确定自己的上行发送波束或根据上行发送波束来确定自己的下行接收波束。

初始接入的4步随机接入过程(或，称为4-step RACH SDT)，即通过Msg3发送小数据。
初始接入的2步随机接入过程(或，称为2-step RACH SDT)，即通过MsgA发送小数据。
CG(Configure Grant，配置授予)SDT业务过程，即通过网络设备配置的专属上行物理上行共享信道(Physical Uplink Shared Channel，PUSCH)资源(如配置授权(Configured Grant，CG)资源；或，预配置上行链路资源(Preallocated Uplink Resource，PUR))发送小数据。
3、随机接入信道时机(Random access channel Occasion，RO)

下面参考附图对本公开实施例所提供的随机接入方法/装置/设备及存储介质进行详细描述。
图2为本公开实施例所提供的一种随机接入方法的流程示意图，该方法由终端设备执行，如图2所示，该随机接入方法可以包括以下步骤：
步骤201、响应于支持波束互易性的终端设备触发RA过程，基于波束互易性确定终端设备的发送和/或接收波束。
在本公开的一个实施例之中，该RA过程可以包括以下任一种：
与SDT相关的RA过程(后续简称为RA-SDT过程)；
非SDT相关的RA过程(后续简称为RA-non-SDT过程)。
以及，在本公开的一个实施例之中，上述的波束互易性为不需要波束扫描的波束互易性，即不需要下行波束扫描和/或上行波束扫描的波束互易性。
此外，在本公开的一个实施例之中，可以预先基于协议约定，针对于支持波束互易性的终端设备，其必须要基于波束互易性实现RA过程中的传输。
进一步地，在本公开的一个实施例之中，当支持波束互易性的终端触发了RA过程后，该终端设备通常需要向网络设备指示该终端设备触发的RA过程是否是基于波束互易性来实现传输的RA过程，以便当该RA过程是基于波束互易性来实现传输的RA过程时，网络设备后续可以进一步确定网络设备是否要基于终端设备的波束互易性实现当前触发的RA过程中的传输。
其中，在本公开的一个实施例之中，终端设备向网络设备指示RA过程是否是基于波束互易性来实现传输的RA过程的方法可以为以下任一种：
第一种：终端设备通过基于某些特定的RO和/或前导码preamble触发RA过程以向网络设备隐式指示该终端设备触发的RA过程是否是基于波束互易性来实现传输的RA过程。
具体的，在本公开的一个实施例之中，支持波束互易性的终端设备会先确定出第一映射关系和/或第二映射关系。其中，该第一映射关系可以包括：RA-SDT过程对应的第一RO和/或第一preamble，该第一RO用于：若触发的RA-SDT过程对应的RO为第一RO，则指示终端设备会基于波束互易性实现此次触发的RA-SDT过程中的传输；该第一preamble用于：若触发的RA-SDT过程对应的preamble为第一preamble，则指示终端设备会基于波束互易性实现此次触发的RA-SDT过程中的传输。
该第二映射关系可以包括：RA-non-SDT过程对应的第二RO和/或第二preamble，其中，该第二RO用于：若触发的RA-non-SDT过程对应的RO为第二RO，则指示终端设备会基于波束互易性实现此次触发的RA-non-SDT过程中的传输；该第二preamble用于：若触发的RA-non-SDT过程对应的preamble为第二preamble，则指示终端设备会基于波束互易性实现此次触发的RA-non-SDT过程中的传 输。
以及，当支持波束互易性的终端设备确定出第一映射关系和/或第二映射关系后，若其要触发RA-SDT过程，则会基于第一映射关系确定出第一RO和/或第一preamble，并基于第一RO和/或第一preamble触发RA-SDT过程；若其要触发(或发起)RA-non-SDT过程，则会基于第二映射关系确定出第二RO和/或第二preamble，并基于第二RO和/或第二preamble触发RA-non-SDT过程。
则由上述内容可知，网络设备仅需通过确定终端设备触发的RA过程对应的RO是否为上述的第一RO或第二RO，和/或，确定终端设备触发的RA过程对应的preamble是否为上述的第一preamble或第二preamble，即可确定出终端设备当前触发的RA过程是否是基于波束互易性来实现传输的RA过程。
第二种：终端设备通过向网络设备上报能力信息来指示其触发的RA过程是否是基于波束互易性来实现传输的RA过程。
具体的，在本公开的一个实施例之中，终端设备可以向网络设备上报能力信息，该能力信息用于指示终端设备在RA过程中是否支持波束互易性。其中，当网络设备接收到的终端设备上报的该能力信息指示终端设备在RA过程中支持波束互易性时，由于协议约定了，针对于支持波束互易性的终端设备，其必须要基于波束互易性实现RA过程中的传输，因此，网络设备可以直接知晓该终端设备触发的RA过程应当均是基于波束互易性来实现传输的RA过程。
以及，需要说明的是，在本公开的一个实施例之中，当终端设备通过向网络设备上报能力信息来指示其触发的RA过程是否是基于波束互易性来实现传输的RA过程时，由于网络设备基于终端设备上报的能力信息可直接知晓该终端设备触发的RA过程是否是基于波束互易性来实现传输的RA过程，因此终端设备就无需再通过基于某些特定的RO和/或preamble(如上述的第一RO、第二RO、第一preamble、或第二preamble)来触发RA过程以向网络设备指示其触发的RA过程是否是基于波束互易性来实现传输的RA过程，从而终端设备可以基于任一RO和/或任一preamble来触发RA过程。
此外，在本公开的一个实施例之中，上述能力信息可以承载于信息域中，如可以承载于信息域IE beamcorrespondence-ra-SDT-r18ENUMERATED{supported}。
再进一步地，在本公开的一个实施例之中，上述的基于波束互易性确定所述终端设备的发送和/或接收波束的方法可以包括：
将终端设备接收与当前触发的RA过程对应的RO和/或preamble所关联的同步信号块(Synchronization Signal Block，SSB)时使用的接收波束确定为终端设备的接收波束；再基于波束互易性和终端设备的接收波束确定终端设备的发送波束，也即是，基于波束互易性将该终端设备的接收波束同时确定为终端设备的发送波束，换言之，终端设备会在其接收波束上同时还会进行上行发送。
步骤202、基于终端设备的发送和/或接收波束传输当前触发的RA过程中的信息和/或数据。
具体的，在本公开的一个实施例之中，响应于当前触发的RA过程为RA-SDT过程，则可以基于终端设备的发送波束向网络设备发送信息和数据，以及基于终端设备的接收波束接收网络设备发送的信息和数据；
以及，响应于当前触发的RA过程为RA-non-SDT过程，可以基于终端设备的发送波束向网络设备发送信息，以及基于终端设备的接收波束接收网络设备发送的信息。
如终端设备可以使用终端设备的发送波束来向网络设备发送msg1/msg3/msgA/RA-SDT过程中的小数据，以及，使用终端设备的接收波束接收网络设备发送的msg2/msg4/msgB/RA-SDT过程中的小数据。
综上所述，在本公开实施例提供的随机接入方法之中，响应于支持波束互易性的终端设备触发RA过程，该支持波束互易性的终端设备会基于波束互易性确定终端设备的发送和/或接收波束；之后，该支持波束互易性的终端设备会基于终端设备的发送和/或接收波束传输当前触发的RA过程中的信息和/或数据。也即是，本公开实施例之中，针对于支持波束互易性的终端设备而言，其在RA过程中会基于波束互易性来传输信息和/或数据，从而可以减少波束管理的开销(overhead)，且终端设备侧无需进行波束扫描，则在确保了信息和/或数据能够成功传输的基础上，缩短了终端设备侧的传输流程，提高了传输效率。

其中，在本公开的一个实施例之中，当支持波束互易性的终端设备向网络设备上报了能力信息，且该能力信息指示终端设备支持波束互易性时，则该终端设备触发RA过程时，可以无需基于某些特定的RO和/或preamble(如上述的第一RO、第二RO、第一preamble、或第二preamble)来触发RA过程，而是可以基于任一RO和/或任一preamble来触发RA过程。
步骤403、基于波束互易性确定终端设备的发送和/或接收波束。
步骤404、基于终端设备的发送和/或接收波束传输当前触发的RA过程中的信息和/或数据。

图5为本公开实施例所提供的一种随机接入方法的流程示意图，该方法由网络设备执行，如图5所示，该随机接入方法可以包括以下步骤：

在本公开的一个实施例之中，该RA过程包括以下任一种：
RA-SDT过程；
RA-non-SDT过程。
以及，在本公开的一个实施例之中，该波束互易性为不需要波束扫描(如上行波束扫描和/或下行波束扫描)的波束互易性。
此外，在本公开的一个实施例之中，网络设备确定终端设备触发的RA过程是否是基于波束互易性实现传输的RA过程的方法可以包括以下任一种：
方法一、基于终端设备触发的RA过程对应的RO和/或preamble确定终端设备触发的RA过程是 否是基于波束互易性实现传输的RA过程。
具体的，网络设备可以先确定第一映射关系和/或第二映射关系。其中，所述第一映射关系包括：RA-SDT过程对应的第一RO和/或第一preamble，所述第一RO用于：若触发的RA-SDT过程对应的RO为所述第一RO，则指示终端设备是基于波束互易性实现此次触发的RA-SDT过程中的传输；所述第一preamble用于：若触发的RA-SDT过程对应的preamble为所述第一preamble，则指示终端设备是基于波束互易性实现此次触发的RA-SDT过程中的传输；
所述第二映射关系包括：RA-non-SDT过程对应的第二RO和/或第二preamble，其中，所述第二RO用于：若触发的RA-non-SDT过程对应的RO为所述第二RO，则指示终端设备是基于波束互易性实现此次触发的RA-non-SDT过程中的传输；所述第二preamble用于：若触发的RA-non-SDT过程对应的preamble为所述第二preamble，则指示终端设备是基于波束互易性实现此次触发的RA-non-SDT过程中的传输。
以及，当确定了第一映射关系和/或第二映射关系后，再确定当前触发的RA过程的类型，其中，响应于所述当前触发的RA过程为RA-SDT过程，若所述当前触发的RA过程对应的RO和/或preamble为第一RO和/或第一preamble，确定所述终端设备触发的RA过程是基于波束互易性实现传输的RA过程；响应于所述当前触发的RA过程为RA-non-SDT过程，若所述当前触发的RA过程对应的RO和/或preamble为第二RO和/或第二preamble，确定所述终端设备触发的RA过程是基于波束互易性实现传输的RA过程。
方法二、基于终端设备上报的能力信息确定终端设备触发的RA过程是否是基于波束互易性实现传输的RA过程。
具体的，在本公开的一个实施例之中，由于协议已预先约定了，针对于支持波束互易性的终端设备，其必须要基于波束互易性实现RA过程中的传输。因此，若终端设备上报的能力信息指示所述终端设备在RA过程中支持波束互易性，则网络设备可直接确定所述终端设备触发的RA过程是基于波束互易性实现传输的RA过程。
步骤502、响应于确定终端设备是基于波束互易性实现当前触发的RA过程中的传输，确定网络设备是否要基于终端设备的波束互易性实现当前触发的RA过程中的传输。
其中，在本公开的一个实施例之中，上述的确定网络设备是否要基于终端设备的波束互易性实现当前触发的RA过程中的传输的方法可以包括：
确定网络设备是否支持波束互易性；其中，响应于所述网络设备支持波束互易性，确定所述网络设备要基于终端设备的波束互易性实现当前触发的RA过程中的传输；响应于所述网络设备不支持波束互易性，确定所述网络设备不基于终端设备的波束互易性实现当前触发的RA过程中的传输。
步骤503、响应于确定网络设备要基于终端设备的波束互易性实现当前触发的RA过程中的传输，基于终端设备的波束互易性实现当前触发的RA过程中的信息和/或数据的传输。
其中，在本公开的一个实施例之中，该基于终端设备的波束互易性实现当前触发的RA过程中的信息和/或数据的传输的方法可以包括以下步骤：
将所述当前触发的RA过程对应的RO和/或preamble所关联的SSB的发送波束确定为所述网络设备的发送波束；基于终端设备的波束互易性和所述网络设备的发送波束确定所述网络设备的接收波束，即基于波束互易性将网络设备的发送波束也确定为网络设备的接收波束，换言之，在网络设备的发送波束上也来接收终端设备发送的信息和/或数据。之后，基于所述网络设备的接收波束接收所述终端设备发送的当前触发的RA过程中的信息和/或数据；基于所述网络设备的发送波束向所述终端设备发送当前触发的RA过程中的信息和/或数据。
其中，在本公开的一个实施例之中，响应于所述当前触发的RA过程为RA-SDT过程，接收所述终端设备发送的当前触发的RA过程中的信息和数据；响应于所述当前触发的RA过程为RA-non-SDT过程，接收所述终端设备发送的当前触发的RA过程中的信息。以及，响应于所述当前触发的RA过程为RA-SDT过程，向所述终端设备发送当前触发的RA过程中的信息和数据；响应于所述当前触发的RA过程为RA-non-SDT过程，向所述终端设备发送当前触发的RA过程中的信息。

将所述当前触发的RA过程对应的RO和/或preamble所关联的SSB的发送波束确定为所述网络设备的发送波束；利用所述网络设备的发送波束向所述终端设备发送当前触发的RA过程中的信息和/或数据；基于所述网络设备的发送波束进行上行波束扫描以接收所述终端设备发送的当前触发的RA过程中的信息和/或数据。
其中，在本公开的一个实施例之中，由于网络设备已经确定了终端设备触发的RA过程是基于波束互易性实现传输的RA过程，也即是，终端设备的发送波束和终端设备的接收波束为同一波束，并且，由于网络设备的发送波束实质为当前触发的RA过程对应的RO和/或preamble所关联的SSB的发送波束，其与终端设备的发送波束和终端设备的接收波束也存在波束互易性，因此，网络设备在进行上述的上行波束扫描时，只需基于网络设备的发送波束在该网络设备的发送波束附近做小范围的上行波束扫描即可接收到终端设备发送的当前触发的RA过程中的信息和/或数据，则本公开中的波束扫描范围较小，提高了波束扫描的效率，确保了信息和/或数据的传输效率。
