背景技术
目前，用户设备UE接收到网络侧设备发送的随机接入(Random Access，RA)过程的RA资源配置信息后，UE可以选择一个波束及其关联的前导码(Preamble)，然后基于选择的波束和前导码发送携带有前导码编号的第一消息(Msg1)给网络侧设备。网络侧设备接收到Msg1后，可以向UE发送Msg2，Msg2中携带了上行授权(uplink grant)信息和一个前导码编号。如果，该Msg2中的前导码编号与Msg1携带的前导码编号相同，UE认为该RA过程成功，否则UE可以将前导码计数器累加1，并重新发起RA尝试，再次选择RA资源，发送Msg1。
然而，按照上述方法，由于在确认RA失败后再重新进行RA尝试，因此导致RA过程的鲁棒性较差。

下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的RA方法、装置、UE、网络侧设备、通信系统及可读存储介质进行详细地说明。
下面先对相关技术中的RA过程进行简要说明。
(一)、基于非竞争的RA过程：
1、UE接收网络侧设备指示基于非竞争的RA过程对应的RA资源配置信息，该配置信息可以用于波束失败恢复(Beam Failure Recovery，BFR)，切换(Handover，HO)，或者物理下行控制信道(Physical Downlink Control Channel，PDCCH)命令触发的基于非竞争的RA过程。该配置信息会指示基于非竞争的RA过程可适用的波束指示(单边带(Single Side Band，SSB)或者信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)波束)以及关联的非竞争前导码。对于BFR和HO触发的基于非竞争的RA过程，该配置信息还可以包括随机接入时机(RACH Occasion，RO)的配置信息，参考信号接收功率(Reference Signal Receiving Power，RSRP)门限配置。
2、UE在获取配置信息后，对于BFR和HO触发的基于非竞争的RA过程，UE会根据测量的波束质量和RSRP门限，判断是否使用非竞争的RA资源(例如.波束质量高于RSRP门限，才会使用非竞争的RA资源)。随后，UE选择一个波束及其对应非竞争前导码后发送第一消息(携带非竞争Preamble)给网络侧设备。网络侧设备接收到第一消息后给UE发送第二消息(随机接入响应(即Random access response，RAR)给UE，该消息中携带了上行授权信息和RA前导的编号(preamble ID)。如果，该preamble ID与UE发送的第一消息中携带的随机接入前导码的编号相同，UE认为该RA过程成功，否则将前导码传输计数器(PREAMBLE_TRANSMISSION_COUNTER)累加一，并重新发起RA尝试，再次选择RA资源，发送第一消息。
(二)、RA资源选择流程
示例性地，如图2和图3所示，相关技术中的RA资源选择流程可以包括下述的步骤1至步骤6。
步骤1、选择上行(Uplink，UL)载波
具体的，UE根据下行路损参考和第一RSRP门限，先选择一个上行载波。
例如，从正常上行链路载波中选择一个上行载波。
步骤2、选择上行部分带宽(Bandwidth Part，BWP)
具体的，在选择的上行载波的激活的上行部分带宽(Bandwidth Part，BWP)上，如果有RA资源，则UE在当前激活的上行BWP进行RA。否则，UE切换到初始上行BWP。
例如，选择图3中的上行UL BWP0。
在选择上行BWP之后，对于Rel-17CovEnh，如果下行路损参考低于第二RSRP门限并且网络侧设备配置的相应的用于第三消息(Msg3)重复传输的RA资源，则可以请求进行Msg3重复传输。
步骤3、选择RA类型
具体的，对于Rel-16技术，UE还可以根据下行路损参考和RSRP门限(例如第一RSRP门限和第二RSRP门限中的至少之一)选择RA的类型，如4-step RA或2-step RA。
步骤4、选择下行(Download)波束
具体的，在选择RA类型后，E根据测量的L1-RSRP和第三RSRP门限，进行SSB波束的选择。例如，选择图3中的波束1。
步骤5、选择与所选波束关联的一个前导码
具体的，UE根据选择的RA的类型，从选择的SSB关联的对应于该RA类型的前导码中，选择一个前导码。
步骤6、确定与所选波束关联的RO资源
具体的，UE根据选择的RA的类型，从选择的SSB关联的对应于选择的RA类型 的RO资源中，随机等概率地选择一个RO资源。例如，选择波束1关联的RO 1。
根据对上述(一)和(二)的描述可知，相关技术中UE在确认RA失败后再重新进行RA尝试，从而导致非竞争RA过程的鲁棒性较差。
本申请实施例提供的RA方法可以应用于基于第一消息重复传输的RA过程，通过该方法，UE可以获得网络侧设备指示的基于第一消息重复传输的RA过程对应的RA资源配置信息，从而UE可以基于该配置信息进行第一消息重复传输的RA过程，提高提升RA过程的鲁棒性。
本申请实施例提供了一种RA方法，图4示出了本申请实施例提供的RA方法的流程示意图，如图4所示，本申请实施例提供的RA方法可以包括下述的步骤400至步骤402。
步骤400、网络侧设备向UE发送配置信息。
步骤401、UE接收配置信息。
其中，上述配置信息可以用于配置：基于第一消息重复传输的RA过程对应的RA资源。
可选地，上述配置信息可以用于配置以下至少之一：基于非竞争的第一消息重复传输的第一RA过程对应的第一RA资源；基于竞争的第一消息重复传输的第二RA过程对应的第二RA资源。如此，由于配置信息可以配置第一RA资源和第二RA资源中的至少之一，因此可以提高UE成功进行第一消息重复传输概率。
可选地，上述配置信息还可以用于配置以下至少之一：基于竞争的不适用第一消息重复传输的第三RA过程对应的第七RA资源；基于非竞争的不适用第一消息重复传输的第四RA过程对应的第八RA资源。如此，使得UE在无法进行第一RA过程和第二RA过程时，可以基于第七RA资源进行第三RA过程，或者基于第八RA资源进行第四RA过程。如此可以进一步提高RA过程的鲁棒性。
可选地，上述配置信息可以包括以下至少之一：资源选择门限；第一重复传输指示；第二重复传输指示；第一RA资源的第一资源集合列表；第二RA资源的第二资源集合列表；第三重复传输指示；第一消息的总重复传输次数；目标波束标识。
其中，第一重复传输指示用于指示触发所述第一RA过程；第二重复传输指示用于指示重复传输所述第一消息所使用的波束模式；每个资源集合列表包括至少一个资源集合元素，每个资源集合元素指示所述第一RA资源或所述第二RA资源中的至少一个RA资源；第三重复传输指示用于指示所述第一资源集合列表或所述第二资源集合列表中包括的一个资源集合元素；目标波束标识用于指示目标波束，所述目标波束关联所述第一RA资源或所述第二RA资源中的一个或多个RA资源。
可选地，第一重复传输指示可以通过第一PDCCH或者第一无线资源控制(Radio Resource Control，RRC)专用信令配置。如果第一重复传输通过第一PDDCH配置，那么当第一PDDCH中对应第一重复传输指示的第一索引域值为1时，第一重复传输指示用于UE触发基于非竞争的第一消息重复传输的第一RA过程；另外，如果此时第一PDDCH中还携带了第三重复传输指示，此时UE会忽略第一PDCCH中携带的前导码索引(preamble index)域或SSB索引域。可选地，该第一PDDCH中还包括物理随机接入信道(Physical Random Access Channel，PRACH)的掩码(mask)索引域；第一索引域位于该掩码索引域之后。
可选地，目标波束标识可以通过配置信息中的第二PDCCH或第二RRC专用信令进行指示。
可选地，第三重复传输指示可以通过第三PDCCH或第三RRC专用信令进行指示。
可选地，每个资源集合元素指示的RA资源可以包括一个或多个波束关联的至少部分波束资源，该一个或多个波束为配置信息配置的RA资源所关联的至少部分波束。 如此可以基于波束从每个资源集合元素指示的RA资源中进行RA资源的选择。
关于资源选择门限：
可选地，资源选择门限可以包括以下至少之一：第一门限、第二门限，第三门限，第四门限、第五门限和第六门限。
其中，第一门限用于UE判断是否选择基于第一消息重复传输的RA过程对应的RA资源；第二门限用于第一RA过程的波束选择；第三门限用于第二RA过程的波束选择；第四门限用于UE判断是否选择基于竞争的第三消息重复传输的RA过程对应的RA资源；第五门限用于基于非竞争的不适用第一消息重复传输的RA过程(即第四RA过程)的CSI-RS波束选择；第六门限用于基于竞争的第三消息重复传输的RA过程的波束选择。
下面对第一门限、第二门限和第三门限进行详细说明。
可选地，上述第一门限具体可以用于UE判断是否选择基于第一消息重复传输的随机接入过程对应的随机接入资源。
针对第一门限：如果网络侧设备配置了第二RA资源或第七RA资源，则网络侧设备可以配置第一门限，即配置信息中可以包括：第二RA资源或第七RA资源，且包括第一门限。
可选地，在配置信息配置了第二RA资源和第七RA资源的情况下，若配置信息中不包括第一门限，并包括第四门限，则UE可以将第四门限的值设定为第一门限的值。
又可选地，第一门限的值不期望大于第四门限，或者说，第一门限的值小于或等于第四门限。
可选地，第三门限可以包括第一子门限和第二子门限。其中，第一子门限用于基于非竞争的第一消息重复传输的RA过程的SSB波束选择，第一子门限用于基于非竞争的第一消息重复传输的RA过程的CSI-RS波束选择。
针对第一子门限：如果网络侧设备配置了第一RA资源，第二RA资源，第七RA资源，第八RA资源，第一RA资源中包括关联SSB波束的RA资源，第八RA资源中包括以下至少之一：关联SSB波束的RA资源，关联CSI-RS波束的RA资源，那么网络侧设备可以配置第一子门限和第三门限，即配置信息中可以包括第一子门限和第三门限。
进一步地，若网络侧设备未配置第一子门限，但配置了第三门限，则UE可以将第三门限的值设定为第一子门限的值。
可选地，如果网络侧设备配置了第一RA过程对应的关联SSB波束的RA资源，则网络侧设备还可以同时配置第二RA资源。
可选地，如果网络侧设备配置了第一RA资源，第二RA资源，第三RA资源和第四RA资源，且第一RA资源中包括关联CSI-RS波束的RA资源，第四RA资源中包括：关联CSI-RS波束的RA资源，那么网络侧设备可以配置第二子门限和第五门限。进一步地，若网络侧设备未配置第二子门限，但配置了第五门限，则UE可以在接收到配置信息后，将第五门限的值设置为第一子门限的值。
可选地，如果网络侧设备配置了基于非竞争的第一消息重复传输的RA过程对应的关联CSI-RS波束的RA资源，则网络侧设备还会同时配置基于竞争的第一消息重复传输的RA过程对应的RA资源(即第二RA资源)。
针对第三门限：如果网络侧设备配置了第二RA资源，第八RA资源，以及第六门限，若此时第三门限没有被配置的话，则UE可以将第六门限的值设定为第三门限的值。
可选地，当第三门限用于选择SSB波束时，第六门限为用于基于竞争的第三消息 重复传输的RA过程的SSB波束选择的门限；当第三门限用于选择SSB波束时，第六门限为用于基于竞争的第三消息重复传输的RA过程的CSI-RS波束选择的门限。
可选地，图5示出了资源选择门限中各门限间大小关系的一种可能的示意图。从图5可以看出，通常情况下，资源选择门限中各门限按照值由大至小的顺序排列为：第五门限、第六门限、第四门限、第一门限，第一子门限、第二子门限以及第三门限。
可选地，资源选择门限中的各门限可以为RSRP门限，也可以为其他任意可能的与质量相关的门限，具体可以根据实际使用需求确定，本申请不作限定。
关于第二重复传输指示：
可选地，第二重复传输指示可以指示第一波束模式或第二波束模式。
第一波束模式为：不同次重复传输采用相同波束进行传输；第一波束模式为：不同次重复传输采用不同波束进行传输。
需要说明的是，“不同次重复传输采用不同波束进行传输”可以理解为：采用至少两个波束关联的全部或部分资源进行第一消息的重复传输。
“不同次重复传输采用相同波束进行传输”可以理解为：采用一个波束关联的全部或部分资源进行第一消息的重复传输。
关于第一RA资源的第一资源集合列表：
本申请实施例中，第一资源集合列表中的每个资源集合元素可以指示第一RA资源中的至少一个RA资源。
本申请实施例中，第二资源集合列表中的每个资源集合元素可以指示第二RA资源中的至少一个RA资源。
通常情况下，配置信息至少配置第一RA资源。本申请实施例提供的RA方法中，UE优先进行基于非竞争的第一消息重复传输的RA过程。
如此，由于配置信息可以配置资源选择门限、第一重复传输指示、第二重复传输指示、所述第一RA资源的第一资源集合列表、所述第二RA资源的第二资源集合列表、第三重复传输指示、所述第一消息的总重复传输次数及目标波束标识中的至少之一，因此使得UE在接收到配置信息后，通过配置信息中的一种或多种信息进行随机接入资源的选择，从而可以提高UE进行第一消息重复传输的随机接入资源的方式的灵活性和多样性。
可选地，上述配置信息配置的RA资源可以关联至少一个波束，该配置信息配置的RA资源可以包括以下至少之一：该至少一个波束关联的第二波束资源；RA过程相关的配置参数。
其中，第二波束资源可以包括以下至少之一：上述至少一个波束中的每个波束关联的重复传输次数；上述至少一个波束中的每个波束关联的前导码资源；上述至少一个波束中的每个波束关联的RO资源；
上述至少一个波束中的每个波束关联的波束模式。
需要说明的是，该至少一个波束是配置信息配置的，并且，该至少一个波束也可以称为RA资源的一部分。
可选地，RA过程相关的配置参数可以包括前导码接收目标功率等。
如此，由于配置信息配置的RA资源可以对应至少一个波束，因此使得UE接收到该配置信息后，可以通过选择波束的方式，从配置信息配置的RA资源中选择用于第一消息重复传输的RA资源，从而可以准确选择RA资源。
步骤402、UE基于配置信息，进行第一消息的重复传输。
本申请实施例中，UE在接收到配置信息后，可以基于配置信息选择RA资源(例如下述的目标RA资源)，然后再基于选择的RA资源进行第一消息的重复传输。
可选地，若目标RA资源为从第一RA资源中选择的，则UE可以基于目标RA资 源，进行第一RA过程中的第一消息的重复传输；若目标RA资源为从第二RA资源中选择的，则UE可以基于目标RA资源，进行第二RA过程中的第一消息的重复传输。
可选地，UE可以通过UE中的媒体访问控制(Media Access Control，MAC)实体选择目标RA资源，然后MAC实体可以指示UE中的物理层根据目标RA资源进行第一消息的重复传输。
可选地，本申请实施例中，上述步骤402具体可以通过下述的步骤402a实现。
步骤402a、
UE基于配置信息和第一规则，进行第一消息的重复传输。
下面对第一规则进行详细说明。
可选地，假设第一RA资源关联N个第一波束，和/或，第二RA资源关联M个第二波束，N和M可以为正整数；那么第一规则可以包括以下规则1至规则12中的至少之一：
可以理解，N个第一波束为第一RA过程对应的波束，M个第二波束为第一RA过程对应的波束，且N个第一波束和M个第二波束均由网络侧设备进行配置。
规则1：若下行路损参考对应的测量值小于第一门限，则UE认为第一消息重复传输适用于当前RA过程。否则，UE认为第一消息重复传输不适用于当前RA过程。
进一步可选地，规则1具体可以为：若配置信息配置了第二RA资源，第八RA资源，并且下行路损参考对应的测量值(如RSRP)小于第一门限(为RSRP门限)，则UE认为第一消息重复传输适用于当前RA过程。否则，UE认为第一消息重复传输不适用于当前RA过程。
本申请实施例中，当配置信息中包括第一门限时，下行路损参考对应的测量值小于第一门限是UE进行第一消息的重复传输的前提。
需要说明的是，上规则1是以下行路损参考对应的测量值与第一门限之间的大小关系，判断第一消息重复传输是否适用于当前RA过程的，实际实现中，UE还可以通过其他任意可能的方法判断第一消息重复传输是否适用于当前RA过程，具体可以根据实际使用需求确定。
规则2：若N个第一波束中的至少一个第一波束的测量值大于第二门限，则UE选择至少一个第一波束中的至少部分第一波束关联的全部或部分RA资源作为目标RA资源。
本申请实施例中，目标RA资源可以用于UE进行第一消息的重复传输。也就是说，UE在选择目标RA资源后，可以基于目标RA资源，重复传输第一消息。
需要说明的是，实际实现中，UE可以基于目标RA资源和该至少部分第一波束，进行第一消息的重复传输。
可选地，规则2中的至少一个第一波束可以为：至少一个SSB波束(第二门限具体为第一子门限)，或至少一个CSI-RS波束(第二门限具体为第二子门限)。
规则2中的至少一个第二波束可以为：至少一个SSB波束(第三门限具体用于选择SSB波束)，或至少一个CSI-RS波束(第三门限用于选择CSI-RS波束)。
规则3：若配置信息配置了第一RA资源和第二RA资源，则UE选择第二RA资源中的全部或部分RA资源作为候选目标RA资源。
可选地，候选目标RA资源可以是基于以下之一确定的：从第二RA资源中随机选择；从M个第二波束关键的RA资源中随机选择；基于M个第二波束中满足第二条件的第二波束确定，例如将满足第二条件的第二波束所关联的全部或部分RA资源，确定为目标候选RA资源。其中，第二条件为：波束的测量值大于第三门限。
可选地，UE可以在认为第一消息重复传输适用于当前随机接入过程的情况下，基于规则3选择候选目标RA资源。
当然，实际实现中，UE还可以在通过规则2选择目标RA资源失败(即没有选择到合适的目标RA资源)后，再基于规则3选择候选目标RA资源，以节省功耗。
规则4：若第三波束关联的波束模式为第一波束模式，则UE选择第三波束关联的全部或部分RA资源作为目标RA资源。
规则5：若第三波束关联的波束模式为第二波束模式，则UE选择第三波束关联的部分RA资源和至少一个第四波束关联的部分RA资源作为目标RA资源。
其中，第三波束为N个第一波束中的一个；第四波束为N个第一波束中的至少一个。第一波束模式为：不同次重复传输采用相同波束进行传输；第一波束模式为：不同次重复传输采用不同波束进行传输。
在规则4和规则5中，每个第一波束可以关联一个波束模式；换言之，每个第一波束与一个波束模式具有关联关系。可以理解，每个第一波束关联的波束模式可以通过一个指示信息指示，例如通过一个第二重复传输指示进行指示。即这种情况下，每个第一波束可以关联一个第二重复传输指示。
可选地，每个第一波束关联的波束模式可以相同，也可以不同。例如，波束1对应第一波束模式，波束2对应第二波束模式。
可选地，第三波束是基于以下至少之一确定：从N个第一波束中随机选择；从第五波束中随机选择；其中，第五波束为N个第一波束中满足第一条件的第一波束；第一条件为波束的测量值大于第二门限。
可选地，第三波束可以为UE在接收到上述配置信息后选择的第一个波束。
可选地，可以预先设置选择第三波束的优先级，例如，“从第五波束中随机选择”的优先级高于“从N个第一波束中随机选择”的优先级。
如此，由于可以从N个第一波束中随机选择第三波束，或从第五波束中随机选择第三波束，因此可以提高选择第三波束的灵活性。
可选地，第四波束是基于以下至少之一确定：从N个第一波束中随机选择；从第五波束中随机选择；
基于第一消息的总重复传输次数；基于第三波束；基于第三波束关联的第一波束资源。
其中，第五波束为N个第一波束中满足第一条件的第一波束；第一条件为波束的测量值大于第二门限；
第一波束资源包括以下至少之一：第三波束关联的重复传输次数；第三波束关联的前导码资源；第三波束关联的随机接入时机RO资源。
如此，第一规则指示UE基于第三波束关联的波束模式，从第一RA资源中选择目标RA资源，可以使得UE选择的目标RA资源与第三波束关联的波束模式相匹配。
规则6：若N个第一波束的测量值均小于或等于第二门限，且配置信息配置了第二RA资源，以及且M个第二波束中的至少一个第二波束的测量值大于第三门限，则UE选择该至少一个第二波束中的至少部分第二波束关联的全部或部分RA资源作为目标RA资源。在规则4中，第二RA资源可以看做是候选目标RA资源。如此，UE可以在通过规则2选择目标RA资源失败的情况下，基于继续基于规则6选择目标RA资源。
规则7：若配置信息配置了第一重复传输指示，则UE将第一RA资源中的第三RA资源作为目标RA资源。
规则8：若配置信息配置了第一资源集合列表，则UE将第一RA资源中的第四RA资源作为目标RA资源。
可选地，当第一规则包括规则7和规则8时，UE具体将UE将第一RA资源中的第四RA资源作为目标RA资源。
可选地，第三RA资源基于以下至少之一确定：从N个第一波束关联的RA资源中随机选择；从第五波束关联的RA资源中随机选择；
其中，第五波束为N个第一波束中满足第一条件的第一波束，或者基于目标波束标识确定；第一条件为波束的测量值大于第二门限。
可选地，第四RA资源是基于以下至少之一确定的：从第一资源集合列表包括的一个资源集合元素所指示的RA资源中随机选择；从第五波束关联的RA资源中随机选择；基于第三重复传输指示；其中，第五波束为N个第一波束中满足第一条件的第一波束，或者基于目标波束标识确定；第一条件为波束的测量值大于第二门限。
如此，一方面，UE可以在第一重复传输指示的触发下，从第一RA资源中选择目标RA资源；另一方面，UE可以从第一RA资源集合列表指示的RA资源中选择目标RA资源。如此可以提高选择目标RA资源的灵活性。
规则9：若第二重复传输指示第一波束模式，则UE选择N个第一波束中的一个第一波束关联的至少部分RA资源作为目标RA资源。
规则10：若第二重复传输指示第二波束模式，则UE选择N个第一波束中的多个第一波束关联的至少部分RA资源作为目标RA资源。
其中，第一波束模式为：不同次重复传输采用相同波束进行传输；
第一波束模式为：不同次重复传输采用不同波束进行传输。
需要说明的是，当UE基于规则10选择目标RA资源时，UE需要进行多次波束选择，且每次选择一个第一波束。其中，每选择一个第一波束后，UE可以基于该第一波束选择目标RA资源中的一部分RA资源，并判断已选择的第一消息重复传输次数是否等于第一消息的总重复传输次数；若判断已选择的Msg1重复传输次数等于Mgs的总重复传输次数，则表示UE已完成目标RA资源的选择，从而UE可以基于已选择的RA资源(即目标RA资源)，进行第一消息的重复传输。否则，UE继续选择下一个第一波束，并基于最近一次选择的波束选择目标RA资源中的一部分RA资源，直至UE判断已选择的Msg1重复传输次数等于Mgs的总重复传输次数时，UE可以基于已选择的RA资源，进行第一消息的重复传输。
如此，在规则9和规则10中，UE可以根据已选择的一个波束(即第三波束)所关联的波束模式，确定UE进行第一消息重复传输所采用的波束模式。
可选地，假设上述候选目标RA资源关联M个第二波束中的至少一个第二波束，那么：第一规则还可以包括下述的规则：
规则：若N个第一波束的测量值均小于或等于第二门限，而且配置信息配置了第二RA资源，则UE可以选择该至少一个第二波束中的至少部分第二波束关联的全部或部分RA资源作为目标RA资源。
对于规则13，“该至少一个第二波束中的至少部分第二波束的关联的全部或部分RA资源”为“候选目标RA资源”中的RA资源。即基于至少部分第二波束从候选目标RA资源中选择目标RA资源。
可选地，对于规则13，目标RA资源可以是基于以下至少之一确定的：
从第一资源集合元素所指示的RA资源中随机选择；从所述至少一个第二波束的一个第二波束所关联的RA资源中随机选择。
其中，第一资源集合元素为第二资源集合列表中的一个，第一资源集合元素指示候选目标RA资源中的至少部分RA资源。进一步可选地，第一资源集合元素可以是基于以下之一确定的：基于目标波束标识；基于第三重复传输指示。
例如，假设配置信息配置了第二资源集合列表和目标波束标识，且目标波束标识指示波束b1，且波束b1关联第二RA资源中的RA资源r1，那么：UE可以将第二资源集合列表中指示RA资源r1的资源集合元素作为第一资源集合元素。
又例如，假设配置信息配置了第二资源集合列表和第三重复传输指示，且第三重复传输指示第二资源集合列表中的资源集合元素e1，那么：第一资源集合元素为资源集合元素e1。
可选地，本申请实施例中，UE在从第一RA资源中选择RA资源失败的情况下，在第二RA资源中选择资源。
如此，在第一RA资源中不包括满足第二门限的RA资源情况下，由于UE还从候选目标RA资源中选择目标RA资源，因此可以提高选择目标RA资源的成功率，从而可以提高随机接入过程的鲁棒性。可选地，用于重复传输的RA资源和用于非重复传输的RA可以同时配置，上述配置信息还可以配置以下至少之一：基于竞争的不适用第一消息重复传输的第三RA过程对应的第七RA资源；基于非竞争的不适用第一消息重复传输的第四RA过程对应的第八RA资源。从而，当第一消息的重复传输不适用于当前RA过程(如下行路损参考对应的测量值大于或等于第一门限)时，UE可以执行第一操作。
其中，第一操作包括以下之一：选择第七RA资源中的至少部分RA资源，并基于选择的RA资源进行第三RA过程；选择第八RA资源中的至少部分RA资源，并基于选择的RA资源进行第四RA过程。
对于UE从第七RA资源或第八RA资源中选择RA资源的描述，具体可以参见上述实施例中，UE选择目标RA资源的相关描述，为了避免重复，此处不再赘述。
可选地，上述第一规则还可以包括下述的规则12：
规则12：若第一RA资源中未配置RO资源，且配置信息配置了第二RA资源，且第二RA资源中配置了RO资源，则UE使用第二RA资源中的RO资源，进行第一RA过程中的第一消息的重复传输。
例如，UE可以基于预设映射关系，进行第二RA资源中的RO资源与M个第一波束之间的映射，以便于每个第一波束与第一RO资源中的至少一个RO资源映射。
可选地，UE在接收到配置信息后，UE可以基于上述规则2至12中的至少一项，选择目标RA资源，然后再基于目标RA资源进行第一消息的重复传输。
可选地，UE接收到配置信息后，可以基于配置信息确定使用规则1至规则12中的哪些规则进行目标RA资源的选择。
下面结合具体示例对本申请实施例提供的RA方法进行示例性地说明。
示例1，以第一规则包括规则2、规则3、规则6和规则13为例。假设配置信息至少配置了：第一RA资源，第二RA资源，第一消息的总重复传输次数，第一子门限，第二子门限和第三门限；又假设第一RA资源关联N个第一波束，第二RA资源关联M个第二波束，并且UE认为Msg1重复传输适用于当前RA过程，那么：UE可以基于配置信息和第一规则，选择目标RA资源，并基于目标RA资源进行第一消息的重复传输，具体的：
首先，UE通过UE中的MAC实体，按照下述的方式1-1或方式1-2，选择目标RA资源。
方式1-1，若N个第一波束中包括测量值大于第二门限的至少一个第一波束，则UE基于规则2选择目标RA资源，具体的：
(1)如果N个第一波束中有至少一个SSB波束的测量值(如RSRP)大于第一子门限，那么UE从该至少一个SSB波束中选择一个SSB波束。或者，(2)如果第一RA资源关联的一个或多CSI-RS波束中至少有一个CSI-RS波束的测量值(如RSRP)大于第二子门限，那么UE可以从该至少一个CSI-RS中选择一个CSI-RS波束。
然后，UE从该SSB波束或CSI-RS波束关联的用于Msg1重复传输的前导码序列号中选择至少一个前导码序列号，并从该SSB波束或CSI-RS波束关联的用于Msg1 重复传输的RO资源中选择最近可传输的RO资源集合，该RO资源集合中包括：最近可传输的一个或多个RO资源，该RO资源集合中RO资源的数量可以基于Msg1的重复传输总次数确定。
需要说明的是，目标RA资源至少可以包括：UE选择的RO资源集合和选择的至少一个前导码序列号对应的前导码。
方式1-2，若N个第一波束的测量值均小于第二门限，则：UE可以基于规则6选择目标RA资源，具体的，UE从M个第二波束中选择一个测量值大于第三门限的波束，若无，则UE从M个第二波束中随机选择一个波束(如SSB波束)。
然后，UE选择该波束对应的用于基于竞争的Msg1重复传输的一个或多个前导码的序列号作为发送前导码的序列号，以及选择该波束对应的用于基于竞争的Msg1重复传输的最近可传输的RO资源集合(包括选择的最近可传输一个或多个RO资源、Msg1重复传输次数)。其中，该RO资源集合根据第二RA资源指示，换句话说，该RO资源集合中的RO资源均为第二RA资源中的部分RO资源。此时，第二RA资源可以认为是候选目标RA资源。
方式1-3，UE基于规则3和规则13选择目标RA资源，假设UE基于规则3从第二RA资源中选择的候选目标RA资源包括：4个第二波束关联的全部RA资源(至少包括最近可传输的RO资源集合、前导码的序列号)，那么：UE可以将4个第二波束中的一个第二波束(例如第六波束)关联的全部或部分RA资源作为目标RA资源。即UE先基于规则3选择候选目标RA资源，然再基于规则13从候选目标RA资源中选择目标RA资源。
其次，UE通过UE中的MAC实体，调度UE中的物理层，使该物理层基于目标RA资源，具体包括：选择的波束、前导码的序列号、最近可传输的RO资源等资源，进行第一消息的重复传输。
如此，由于UE可以先从第一RA资源中选择目标RA资源，并在选择失败的情况下，继续在第二RA资源中选择目标RA资源，因此可以提高UE成功选择到目标RA资源的概率，从而可以提高RA过程的鲁棒性。
示例2：以第一规则包括规则7和规则9为例，假设配置信息配置了第一RA资源，第一消息重复传输4次(即第一消息的总重复传输次数)及第一重复传输指示；其中，第一RA资源关联SSB#0和SSB#1波束(即N(N＝2)个第一波束)。具体的，第一RA资源可以包括：SSB#0关联的前导码序列号#60、RO资源集合1(例如，采用TDMed的RO进行Msg1重复传输)，以及指示第一波束模式的一个第二重复传输指示；SSB#1关联的前导码序列号#61、RO资源集合2，以及指示第一波束模式的一个第二重复传输指示；第一波束模式为：不同次重复传输使用相同波束模式。那么：
首先，UE通过UE中的MAC实体，按照下述的方式2-1或方式2-2，选择目标RA资源。
方式2-1，若配置信息还配置了第一子门限，则：
(1)若N个第一波束中包括至少一个第一波束(如SSB#0)的测量值大于第一门限的测量值大于第一子门限(即第一门限)，则可以从该至少一个第一波束中选择一个第一波束(SSB#0)。然后，由于SSB#0关联第一波束模式，因此UE可以选择SSB#0关联前导码序列号#60，并根据Msg1的总重复传输次数4次和RO资源集合1，确定SSB#0关联的用于Msg1重复传输的最近可传输的4个RO资源(即目标RA资源)。
(2)若N个第一波束的测量值均小于等于第一子门限，则：UE可以从N个第一波束中随机选择一个第一波束(如SSB#60)。然后，由于SSB#0关联第一波束模式，因此UE可以选择SSB#0关联前导码序列号#60，并根据Msg1的总重复传输次数(4 次)和RO资源集合1，确定SSB#0关联的用于Msg1重复传输的最近可传输的4个RO资源(即目标RA资源)。。
方式2-2，UE从N个第一波束中随机选择一个第一波束(如SSB#0)。对于UE基于SSB#0选择目标RA资源的描述参见2-1中的相关描述，为了避免重复，此处不再赘述。
其次，在MAC实体选择出目标RA资源后，该MAC实体可以指示UE的物理层目标RA资源，具体包括：选择的波束、前导码序列号、最近可传输的RO资源集合进行第一消息的重复传输。
可以看出，在示例2中UE是基于相同第一波束关联的RA资源进行第一消息的重复传输的。
可选地，假设示例2中的R0资源集合1包括图6所示的RO资源，那么：如图6所示，UE根据Msg1的总重复传输次数，从RO资源集合1中确定的4个RO资源可以包括：任一帧中第一个子帧#1中的RO1，RO3，以及第二个子帧#2中的RO1，RO3；或者第一个子帧#1中的RO3，以及第二个子帧#1中的RO1，RO3，以及第三个子帧#1中的RO1，以此类推。可以看出，UE可以从RO资源集合1中的RO资源中任意选择可传输的4个RO资源。
其中，如图6所示，每个帧可以包括0～9共十个子帧。每个子帧可以包括多个RO资源(如图6中第二行的每个小格表示一个RO资源)
示例3，以第一规则包括：规则7、规则10为例。假设配置信息至少配置了：第一RA资源，第一重复传输指示，第二重复传输指示，Msg1的总重复传输次数8次(即第一消息的总重复传输次数)；其中，第一RA资源关联2个SSB波束(即N(N＝2)个第一波束，分别为SSB#0和SSB#1)。具体的，第一RA资源包括：SSB#0关联的前导码序列号#60，以及Msg1重复传输次数2次以及RO资源集合1(例如，采用TDMed的RO资源进行Msg1重复传输)；SSB#1关联的前导码序列号#61，Msg1重复传输次数4次以及RO资源集合2；且第二重复传输指示指示：不同次重复传输使用不同波束模式(即第二波束模式)。那么：
首先，UE可以通过UE中的MAC实体，按照下述的方式3-1或方式3-2，选择第1个SSB波束，并基于该SSB波束选择目标RA资源中的部分RA资源。
方式3-1，如果配置信息还配置了第一子门限，那么：若第一RA资源关联的2个SSB波束中有至少一个SSB波束的测量值大于第一子门限，则UE可以从该至少一个SSB波束中选择第1个SSB波束(如选择了SSB#0)；否则，UE从该2个SSB波束中随机选择第1个SSB波束(如随机选了SSB#0)。然后，UE可以选择SSB#0(即第1个SSB波束)关联的用于Msg1重复传输的前导码序列号作为发送前导码的序列号(如，前导码序列号#60)；且根据SSB#0关联的Msg1重复传输次数2次，从SSB#0关联的RO资源集合1中确定用于Msg1重复传输的最近可传输的2个RO资源；再确定UE已选择的Msg1重复传输次数(2次)。方式3-2，UE可以直接从2个SSB波束中随机选择第1个SSB波束(如SSB#0)。然后，UE可以选择SSB#0(即第1个SSB波束)关联的用于Msg1重复传输的前导码序列号(如前导码序列号#60)；且根据Msg1重复传输次数和该SSB波束对应RO集合，确定该SSB波束对应用于基于Msg1重复传输的最近可传输的RO集合(2个RO)，再确定已选择的Msg1重复传输次数(2次)。
其次，UE可以通过UE中的MAC实体，继续选择第2个SSB波束(如选择了SSB#1)。然后，UE可以选择SSB#1关联的用于Msg1重复传输的前导码序列号作为发送前导码序列号(如Preamble#61)；且根据SSB#1关联的Msg1重复传输次数(具体为4次)，从SSB#1关联的RO资源集合2中确定用于Msg1重复传输的最近可传 输的4个RO资源；再确定UE已选择的Msg1重复传输次数(6次，即2次+4次)。由于已选择的Msg1重复传输次数6次＜Msg1的总重复传输次数8次，因此UE可以继续基于配置信息、规则7和规则10，选择第3个SSB波束(例如UE再次选择了SSB#0)。然后，UE可以选择SSB#1关联的Preamble#61；且根据SSB#1关联的Msg1重复传输次数(具体为4次)，从SSB#1关联的RO资源集合2中再确定最近可传输的2个RO资源(与第1次选择的RO资源不同)，此时，由于已选择的Msg1重复传输次数8次＝Msg1的总重复传输次数8次，因此UE可以确定已经完成目标RA资源的选择。
从而，在MAC实体选择出目标RA资源后，该MAC实体可以指示UE的物理层目标RA资源，具体包括：选择的波束、前导码序列号、最近可传输的RO资源集合进行第一消息的重复传输。
示例4，以第一规则包括规则7和规则8为例，假设配置信息配置了：第一RA资源和第一资源集合列表，且第一RA资源指示的N个第一波束中包括SSB#0、SSB#1、SSB#2和SSB#3，第一资源集合元素列表包括资源集合元素#e0和资源集合元素#e1，#e1和#e2分别为第一资源集合元素列表中的2个资源集合元素的索引值。
其中，资源集合元素#e0指示：SSB#0关联的前导码序列号#60、Msg1重复传输次数4次以及RO资源集合1(例如，采用TDMed的RO资源进行Msg1重复传输)；SSB#1关联的前导码序列号#61、Msg1重复传输次数4次以及RO资源集合2。资源集合元素#e1指示：SSB#1关联的前导码序列号#61、Msg1重复传输次数2次以及RO资源集合2；SSB#2关联的前导码序列号#62、Msg1重复传输次数4次以及RO资源集合3；SSB#3关联的前导码序列号#63、Msg1重复传输次数2次以及RO资源集合3。可以理解，波束关联的前导码序列号、Msg1重复传输次数以及RO资源集合可以波束关联的波束资源。那么UE可以基于方式4-1、方式4-2或方式3，进行第一消息的重复传输。
方式4-1，当UE确认第一消息重复传输适用于当前RA过程时，UE可以按照上述示例1的的方式从N个第一波束中选择一个SSB波束(如选择了SSB#0)。然后UE可以根据SSB#和第一资源集合列表，选择用于Msg1重复传输的所有发送波束，发送前导码序列号以及最近可传输的RO集合。具体的：UE选择出SSB#0后，UE可以从第一资源集合列表中找出包括SSB#0关联的波束资源的资源集合元素#e0和资源集合元素#e1，并随机选择资源集合元素#e0；从而UE可以根据资源集合元素#e0，确定Msg1重复传输中需要先按照SSB#0和前导码序列号#60，在RO资源集合1中的4个RO资源上进行Msg1重复传输次数4次；然后再按照SSB#1，前导码序列号#61，在RO资源集合2中的4个RO资源上进行4次Msg1重复传输。可以看出目标RA资源包括：前导码序列号#60，RO资源集合1中的4个RO资源，前导码序列号#61，RO资源集合2中的4个RO资源。
在UE选择出目标RA资源之后，UE的MAC实体可以依次指示UE的物理层根据所选择的SSB波束(即SSB#0和SSB#1)、前导码序列号(即前导码序列号#60和前导码序列号#61)以及RO资源(即RO资源集合1中的4个RO资源和RO资源集合2中的4个RO资源)，进行第一消息的重复传输。
方式4-2，假设配置信息还：第一重复传输指示和目标波束标识(通过PDCCH或者RRC专用信令配置)；其中，PDCCH中对应第一重复传输指示的指示域为1，目标波束标识指示SSB#0；那么：UE可以根据PDCCH指示的目标波束标识选择SSB#0(即第五波束基于目标波束标识确定)，然后根据选择的SSB#0和第一资源集合列表，确定用于第一消息重复传输对的所有发送波束，发送签到码序列号以及最近可传输的RO资源集合。具体地，在确定出SSB#0后，UE可以从第一资源集合列表中找出包括 SSB#0关联的波束资源的资源集合元素#e0和资源集合元素#e1，并随机选择资源集合元素#e0；从而UE可以根据资源集合元素#e0，确定Msg1重复传输中需要先按照SSB#0和前导码序列号#60，在RO资源集合1中的4个RO资源上进行Msg1重复传输次数4次；然后再按照SSB#1，前导码序列号#61，在RO资源集合2中的4个RO资源上进行4次Msg1重复传输。可以看出目标RA资源包括：前导码序列号#60，RO资源集合1中的4个RO资源，前导码序列号#61，RO资源集合2中的4个RO资源。需要说明的是，资源集合元素#e1可以指示基于SSB#1重复发送第一消息4次，然后基于SSB#1发送4次。
在UE选择出目标RA资源之后，UE的MAC实体可以依次指示UE的物理层根据所选择的SSB波束(即SSB#0和SSB#1)、前导码序列号(即前导码序列号#60和前导码序列号#61)以及RO资源(即RO资源集合1中的4个RO资源和RO资源集合2中的4个RO资源)，进行第一消息的重复传输。
方式3假设配置信息还配置了：第一重复传输指示和第三重复传输指示(通过第三PDCCH或者第三RRC专用信令配置)；该第三重复传输指示指示第一资源集合列表中的资源集合元素的索引值，则UE根据第三重复传输指示指示的索引值(例如#e1)，确定资源集合元素#e1。从而UE可以根据资源集合元素#e0，确定Msg1重复传输中需要先按照SSB#0和前导码序列号#60，在RO资源集合1中的4个RO资源上进行Msg1重复传输次数4次；然后再按照SSB#1，前导码序列号#61，在RO资源集合2中的4个RO资源上进行4次Msg1重复传输。可以看出目标RA资源包括：前导码序列号#60，RO资源集合1中的4个RO资源，前导码序列号#61，RO资源集合2中的4个RO资源。需要说明的是，资源集合元素#e1可以指示基于SSB#1重复发送第一消息4次，然后基于SSB#1发送4次。
在UE选择出目标RA资源之后，UE的MAC实体可以依次指示UE的物理层根据所选择的SSB波束(即SSB#0和SSB#1)、前导码序列号(即前导码序列号#60和前导码序列号#61)以及RO资源(即RO资源集合1中的4个RO资源和RO资源集合2中的4个RO资源)，进行第一消息的重复传输。
可选地，在上述步骤402之后，本申请实施例提供的RA方法还可以包括下述的步骤403和步骤404，或者可以包括下述的步骤405和步骤406。
步骤403、在UE成功完成第一RA过程的情况下，UE根据第一物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的重复传输次数，发送第一PUSCH。
步骤404、网络侧设备接收第一PUSCH。
其中，第一RA过程为基于非竞争的第一消息重复传输的RA过程，第一PUSCH为网络侧设备发送的随机接入响应(Random Access Response，RAR)所调度的PUSCH。
本申请实施例中，UE在第一消息重复传输后，以RAR调度的第一PUSCH重复传输的假设，进行RAR的解释以及第一PUSCH的发送。
具体的，如果UE使用了基于第一消息重复传输的RA过程对应的RA资源；或者说，UE指示了进行第一消息重复传输，则UE在成功解码出匹配的RAR后，可以根据RAR中的调制与编码策略(Modulation and Coding Scheme，MCS)域，具体根据MCS的高2位比特，确定RAR调度的PUSCH的重复传输次数，并根据确定的重复传输次数进行RAR调度的PUSCH的发送。
上述RAR是网络侧设备在接收到UE重复传输的第一消息后向UE发送的。
如此，在UE成功完成第RA过程的情况下，由于UE可以发送RAR调度的第一PUSCH，因此可以重复发送RAR调度的PUSCH，因此可以提高PUSCH的成功发送概率。
步骤405、在UE成功完成第一RA过程的情况下，UE向网络侧设备上报第一RA 过程的信息。
步骤406、网络侧设备接收第一RA过程的信息。
其中，第一RA过程的信息用于网络侧设备调整第一RA过程对应的资源配置。
可选地，上述第一RA过程的信息可以用于指示以下至少之一：第一RA资源关联的波束中是否包括测量值大于第二门限的波束；UE在第一RA过程中使用的RA资源。其中，第二门限用于基于非竞争的第一消息重复传输的第一RA过程的波束选择。
可选地，对于在第一RA过程中的每一次RA尝试，UE可以上报第一RA资源关联的波束中是否包括测量值大于第二门限的波束。
例如，对于在第一RA过程中的每一次RA尝试，UE可以上报第一RA资源关联的SSB波束中是否包括至少一个SSB波束的测量值大于第一子门限，或者可以上报第一RA资源关联的CSI-RS波束中是否包括至少一个CSI-RS波束的测量值大于第二子门限。
可选地，“UE在第一RA过程中使用的RA资源”可以包括：UE选择的波束的序号，如SSB波束的序号或CSI-RS波束的序号，从选择的波束所对应的RO资源中选中的RO资源，或从选择的波束所对应的RO资源中选中的RO资源的序号。
本申请实施例中，在UE成功完成第一RA过程的情况下，由于UE可以向网络侧设备上报第一RA过程的信息，从而网络侧设备在接收到第一RA过程的信息后，可以基于该信息调整第一RA过程对应的资源配置，因此可以使得调整后的第一RA过程的资源配置与第一规则的匹配度更高。
