本申请基于申请号为“202011449002.0”、申请日为2020年12月9日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此以引入方式并入本申请。
技术领域
本申请的实施例涉及通信技术领域，特别涉及一种随机接入信道的配置方法、装置、电子设备和存储介质。
背景技术
2步随机接入(2step Random access，2步RA)是R16协议规范引入的一种新的接入方式，将原有的4步RA精简到2步，显著减少了时延，但是并非所有的随机接入场景都可以使用2步RACH。因此，在需要根据不同情况选择使用2步RA还是4步RA再进行相应的RACH配置。目前主要采用的随机信道接入的配置方法是：先根据参考信号接收功率(Reference Signal Receiving Power，RSRP)阈值来进行使用2步RACH还是4步RACH，然后进行同步信号和物理层广播信道块(Synchronization Signal and Physical Broadcast Channel Block，SSB)的选择。
然而，对于选定2步RA的远场用户设备来说，即使能够满足所有的参考信号接收功率阈值条件，可能会出现由于不能满足硬件带来的缓存限制，如不满足定时提前量(Timing Advance，TA)的条件或者不满足msgA的上行物理共享信道(msgA-Physical Uplink Shared Channel，msgA-PUSCH)解调性能，导致2步RA失败，需要回退到4步RA，降低系统的接入成功率同时增加时延。

具体实施方式
本申请实施例的主要目的在于提出一种随机接入信道的配置方法、装置、电子设备和存储介质，旨在实现能够满足硬件带来的缓存限制，使得能够基于波束配置随机接入信道、系统的接入成功率提高、时延减小。
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请的各实施例进行详细的阐述。然而，本领域的普通技术人员可以理解，在本申请各实施例中，为了使读者更好地理解本申请而提出了许多技术细节。但是，即使没有这些技术细节和基于以下各实施例的种种变化和修改，也可以实现本申请所要求保护的技术方案。以下各个实施例的划分是为了描述方便，不应对本申请的具体实现方式构成任何限定，各个实施例在不矛盾的前提下可以相互结合相互引用。
本申请的第一实施例涉及一种随机接入信道的配置方法，执行主体为用户设备，如图1所示，具体包括：
步骤101，接收无线资源管理RRC消息，其中，RRC消息携带SSB与随机接入类型RA-TYPE之间的关联信息，RA-TYPE包括2步随机接入RA和4步RA。
具体地说，在本实施例中，SSB是同步信号和物理层广播信道块，SSB与随机接入类型(Random Access-Type，RA-TYPE)之间的关联信息可以是以位图的形式表示，也可以是以掩码的形式表示。当然，以上仅为具体的举例说明，在实际的使用过程中SSB与RA-TYPE之间的关联信息的表示形式还可以包括其他形式，此处不做一一赘述。而且RRC消息携带SSB与RA-TYPE之间的关联信息主要可以根据用户设备自身业务类型和需求或者根据波束宽窄选择RA-TYPE，如远场的用户设备需要尽量保证接入成功率，因此，根据4步RA不会发生满足RSRP条件却不能够满足硬件限制条件的情况，将对应远场波束的特定的SSB设定 为4步RA，避免接入失败。
更具体地说，当SSB与RA-TYPE之间的关联信息以位图的形式表示时，如图2所示，可以将SSB与RA-TYPE之间的关联信息的位图名称定义为RATypeSSBbitmap，RATypeSSBbitmap每一位的数值直接指示SSB关联上的RA-TYPE的预设值，其中，RATypeSSBbitmap的长度是系统使用的SSB的个数，当RATypeSSBbitmap某一位上的数值位为1时，表示SSB对应的RA-TYPE为2步RA，即配置2步RACH波束。当SSB与RA-TYPE之间的关联信息以掩码的形式表示时，如下表所示，可以将SSB与RA-TYPE之间的关联信息的掩码名称定义为RATypeSSBResMaskIndex，一个RATypeSSBResMaskIndex对应一种预先设置的关联关系，关联关系是SSB与RA-TYPE的映射关系，RATypeSSBResMaskIndex的长度可以为4比特，表格内容中所指示的SSB均采用2步RA。
RATypeSSBResMaskIndex SSB Resource
0 all SSBs
1 every odd SSBs
2 every even SSBs
3 the first half SSBs
4 the last half SSBs
5 first 8 SSBs
6 first 16 SSBs
7 last 8 SSBs
8 reserved
9 reserved
10 reserved
11 reserved
12 reserved
13 reserved
14 reserved
15 reserved
需要说明的是，协议规定SSB最大个数为64个，位图最多需要支持64比特，掩码按上述示例则最多需要支持4比特，对于携带SSB与RA-TYPE之间的关联信息的RRC消息影响不大。由于SSB重配的过程中系统需要断网，因此，SSB进行重配时也需要将RRC消息中携带的SSB与RA-TYPE的关联信息的位图或者掩码进行相应的重配。虽然上述均为RRC消息携带SSB与RA-TYPE的关联信息的情况，但是RRC消息还存在不携带SSB与RA-TYPE之间的关联信息的情景，具体地说，基于用户设备和基站对RA-TYPE的选择采用一种双方约定的规则，例如，规则可以是当满足SSB号<M时均采用2步RA，M是根据实际情况选定的一个正整数，因此基于这种规定了SSB与RA-TYPE的关联关系的规则，仍然可以执行以下步骤，成功完成对随机接入信道的配置。
步骤102，确定待配置的SSB。
具体地说，本实施例是从所有可用的SSB中依据一定规则选取一个SSB，并将选取的这个SSB作为SSB的配置结果。
更具体地说，如图3所示，步骤102包括：
步骤301，获取msgA对同步信号和物理层广播信道块的参考信号接收功率阈值msgA-RSRP-ThresholdSSB和对同步信号和物理层广播信道块的参考信号接收功率阈值RSRP-ThresholdSSB。
步骤302，根据第一阈值条件和第二阈值条件确定所述待配置的SSB，其中，第一阈值条件为存在至少一个SSB的SS-RSRP大于msgA-RSRP-ThresholdSSB，第二阈值条件为存在至少一个SSB的SS-RSRP大于RSRP-ThresholdSSB。
步骤103，根据待配置的SSB与RA-TYPE之间的关联信息确定待配置的RA-TYPE。
需要说明的是，在本实施例中，在实际的应用中，在步骤101之后一般还包含步骤：获取下行链路损失的RSRP，然后根据下行链路损失的RSRP和正常上行链路(Normal UpLink，NUL)载波和补充上行链路(Supplementary UpLink，SUL)载波之间选择的RSRP阈值(rsrp-ThresholdSSB-SUL)的比较结果选择载波类型。但是由于本实施例的解决的问题是如何选择2步RA还是4步RA，而采用2步RA时使用的载波的类型一定是NUL，因此，可以认为，步骤101之后一定会选择NUL作为载波。
具体地说，在本实施例中，由于RRC消息携带SSB对应的RA-TYPE的关联信息，因此，在从所有的SSB中确定了一个待配置的SSB之后，可以直接根据待配置的SSB在SSB对应的RA-TYPE的关联信息中，查找该SSB对应的RA-TYPE，将查找到的RA-TYPE作为待配置的RA-TYPE。
步骤104，根据待配置的SSB和待配置的RA-TYPE完成随机接入信道的配置。
具体地说，在确定待配置的SSB和待配置的RA-TYPE之后，进行相应的变量初始化，就可以完成随机接入信道的配置，接着就直接进行相应消息(msgA或者msg1)的传输。
本申请实施例相对于现有技术而言，接收的RRC消息能够携带SSB与RA-TYPE的关联信息，使得能够确定待配置的SSB之后，根据待配置的SSB与RA-TYPE之间的关联信息得到待配置的RA-TYPE，然后根据待配置的SSB和待配置的RA-TYPE完成随机接入信道的配置。由于SSB与随机接入类型RA-TYPE的关联信息能够直接确定每个SSB对应的待配置RA-TYPE是2步RA还是4步RA，因此可以直接将不能满足硬件限制条件的SSB定义为对应4步RA，使得选定待配置的RA-TYPE时能够满足硬件带来的缓存限制，且待配置的RA-TYPE是基于波束信息SSB来选择的，进而实现基于波束选择随机接入信道的选择、避免2步接入失败以及2步接入失败后回退到4步RA的情况出现，提高了系统的接入成功率、避免了回退带来的时延增加。
本申请的第二实施例涉及一种随机接入信道的配置方法，本实施例与第一实施例大致相同，区别在于，对步骤302进一步进行了细化，本实施例的具体流程如图4所示，具体包括：
步骤401，接收无线资源管理RRC消息，其中，RRC消息携带SSB与随机接入类型RA-TYPE之间的关联信息和msgA的参考信号接收功率阈值msgA-RSRP-Threshold，RA-TYPE包括2步随机接入RA和4步RA。
具体地说，本实施例中的步骤401中RRC消息还携带msgA的参考信号接收功率阈值 msgA-RSRP-Threshold，其他与第一实施例中的步骤101大致相同，此处就不一一赘述。
通过步骤402-步骤409获取待配置的SSB，具体如下：
步骤402，获取msgA对同步信号和物理层广播信道块的参考信号接收功率阈值msgA-RSRP-ThresholdSSB和对同步信号和物理层广播信道块的参考信号接收功率阈值RSRP-ThresholdSSB。
步骤403，根据msgA-RSRP-Threshold确定初始的RA-TYPE。
具体地说，根据获取的下行链路损失的RSRP和msgA-RSRP-Threshold的大小关系确定初始的RA-TYPE，并确定的初始的RA-TYPE进行相应的参数初始化。
需要说明的是，步骤403与现有技术大致相同，此处就不一一赘述。
步骤404，判断初始的RA-TYPE是否为2步RA。
具体地说，若是，执行步骤405，若否，执行步骤406。
步骤405，将第一阈值条件作为阈值条件，其中，第一阈值条件为存在至少一个SSB的SS-RSRP大于msgA-RSRP-ThresholdSSB。
步骤406，将第二阈值条件作为阈值条件，其中，第二阈值条件为存在至少一个SSB的SS-RSRP大于RSRP-ThresholdSSB。
步骤407，判断是否满足阈值条件，若是，执行步骤408，若否，执行步骤409。
步骤408，将任意一个满足阈值条件的SSB作为待配置的SSB。
步骤409，将任意一个SSB作为待配置的SSB。
步骤410，根据待配置的SSB与RA-TYPE之间的关联信息确定待配置的RA-TYPE。
具体地说，本实施例中步骤410与第一实施例中步骤103大致相同，此处就不一一赘述。
步骤411，检测初始的RA-TYPE与待配置的RA-TYPE是否相同。
具体地说，若是，执行步骤413，若否，执行步骤412。
步骤412，将初始的RA-TYPE更改为待配置的RA-TYPE。
具体地说，若初始的RA-TYPE为2步RA、待配置的RA-TYPE为4步RA，执行步骤403实际上会将待配置的RA-TYPE确定为2步RA，执行步骤412之后则将待配置的RA-TYPE由2步RA更改为4步RA。同样地，若初始的RA-TYPE为4步RA、待配置的RA-TYPE为2步RA，执行步骤403实际上会将待配置的RA-TYPE确定为4步RA，执行步骤412之后则将待配置的RA-TYPE由4步RA更改为2步RA。
步骤413，根据待配置的SSB和待配置的RA-TYPE完成随机接入信道的配置。
需要说明的是，在本实施例中，步骤103中的SSB不需要重新进行配置，仍然沿用步骤406得到的SSB的配置结果。具体地说，在根据第二阈值确定2步RA的SSB待配置的的RA资源上的前导码资源，所配置的前导码资源均可用于2步RA，而不用遵循第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)规定的配置所指示的内容。此时在未指示2-stepRA的SSB待配置的RA资源上的前导码资源，所配置的前导码资源均可用于4步RA，而不用遵循3GPP规定的配置所指示的内容。
本实施例相对于现有技术而言，在第一实施例的基础上，由于直接承接了现有技术中确定SSB的步骤，即步骤401到步骤409，使得对现有随机接入信道配置的流程改动少，进而能够兼容现有协议，减少了方法实现的难度。
本申请的第三实施例涉及一种随机接入信道的配置方法，本实施例与第一实施例大致相 同，区别在于，如图5所示，对现有技术中确定待配置的SSB的过程进行了简化，具体地包括：
步骤501，接收无线资源管理RRC消息，其中，RRC消息携带SSB与随机接入类型RA-TYPE之间的待配置的信息，RA-TYPE包括2步随机接入RA和4步RA。
具体地说，本实施例中的步骤401与第一实施例中的步骤101大致相同，此处就不一一赘述。
通过步骤502-步骤507获取待配置的SSB，具体如下：
步骤502，获取msgA对同步信号和物理层广播信道块的参考信号接收功率阈值msgA-RSRP-ThresholdSSB和对同步信号和物理层广播信道块的参考信号接收功率阈值RSRP-ThresholdSSB。步骤503，判断是否满足第一阈值条件。
需要说明的是，第一阈值条件为存在至少一个SSB的SS-RSRP大于msgA-RSRP-ThresholdSSB。
具体地说，若是，执行步骤504，若否，执行步骤505。
步骤504，将任意一个满足第一阈值条件的SSB作为待配置的SSB。
步骤505，判断是否满足第二阈值条件。
需要说明的是，第二阈值条件为存在至少一个SSB的SS-RSRP大于RSRP-ThresholdSSB。
具体地说，若是，执行步骤506，若否，执行步骤507。
步骤506，将任意一个满足第二阈值条件的SSB作为待配置的SSB。
步骤507，将任意一个SSB作为待配置的SSB。
步骤508，根据待配置的SSB与RA-TYPE之间的关联信息确定待配置的SSB对应的待配置的RA-TYPE。
具体地说，本实施例中的步骤508与第一实施例中的步骤103大致相同，此处就不一一赘述。
步骤509，根据待配置的SSB和待配置的RA-TYPE完成随机接入信道的配置。
具体地说，本实施例中的步骤509与第一实施例中的步骤104大致相同，此处就不一一赘述。需要说明的是，在本实施例中，已指示2-stepRA的SSB关联的RA资源上的前导码资源，所配置的前导码资源均可用于2步RA，而不用遵循3GPP规定的配置所指示。此时在未指示2步RA的SSB关联的RA资源上的前导码资源，所配置的前导码资源均可用于4-stepRA，而不用遵循3GPP规定的配置所指示。
本实施例相对于现有技术而言，在第一实施例的基础上，由于省略了现有技术中获取第二RA-TYPE的步骤，先从所有的SSB中选择一个BSS作为待配置的SSB，再选择是将2步RA作为待配置的RA-TYPE还是将4步RA作为待配置的RA-TYPE，减少了确定初始的待配置RA-TYPE和相应的初始化操作，使得操作无重复、流程更加简单、时延更小。
本申请的第四实施例涉及一种随机接入信道的配置方法，本实施例与第一实施例大致相同，区别在于，如图6所示，在步骤104之前还包括：
步骤601，若待配置的RA-TYPE为4步RA，判断待配置的SSB的SS-RSRP是否大于预设的msgA的参考信号接收功率阈值msgA-RSRP-Threshold。
具体地说，若是，执行步骤602，若否，执行步骤603。
需要说明的是，在本实施例中，预设的msgA-RSRP-Threshold和第二实施例中提到的现 有技术中的msgA-RSRP-Threshold的具体数值不同，预设的msgA-RSRP-Threshold是人为地根据实际需求设定的数值，通过这个数值，将某些特殊的情况(满足待配置的SSB的SS-RSRP是否大于预设的msgA的参考信号接收功率阈值msgA-RSRP-Threshold)筛选出来，进行相应的操作。因此通过预设数值可以灵活地改变筛选条件，调整实际的执行结果。
步骤602，将待配置的RA-TYPE更新为2步RA。
步骤603，保持待配置的RA-TYPE不变。
具体地说，在本实施例中，在已经确定了待配置的RA-TYPE为4步RA时，SSB的配置结果对应的SS-RSRP大于预设的msgA的参考信号接收功率阈值msgA-RSRP-Threshold，待配置的RA-TYPE会由4步RA更新为2步RA，其他情况不会更新。因此，本实施例的结果实际上是将部分RA-TYPE选定为配置4步RA的SSB更新为配置2步RA。
需要说明的是，在已指示2-stepRA的SSB关联的RA资源上的前导码资源，所配置的前导码资源均可用于2-stepRA，而不用遵循3GPP规定的配置所指示。此时在未指示2-stepRA的SSB关联的RA资源上的前导码资源，按照3GPP协议规定的配置指示。
本实施例相对于现有技术而言，在第一实施例的基础上，能够采用预设的msgA-RSRP-Threshold进一步将部分选定4步RA作为待配置的RA-TYPE更新为将2步RA作为待配置的RA-TYPE，使得时延进一步减小，且能够灵活调整更新所覆盖用户设备的范围。
为了使本领域技术人员能够更清楚地理解以上本申请第一至四实施例公开的随机接入信道的配置方法，本申请第五实施例以如图7所示的波束分配的角度对上述实施例进行说明。
在需要解决远场用户设备因为不满足硬件的限制条件导致2步RA失败的问题时，如图7所示，该小区共有24个窄波束，系统根据自身的2步RA的缓存能力，可计算得到一个最大的实现约束距离，可以采用公式：
Figure PCTCN2021127620-appb-000001
计算最大的实现约束距离，其中，TA为提前定时量，反映了缓存能力限制，c为光速。
当多个用户设备同时接入时，msgA-PUSCH解调性能允许的最大TA差，同样可计算的到波束最大的覆盖距离。
由于最大的实现约束距离涵盖第一、二层波束，但未全部涵盖第三层波束，因此，第三岑波束上会出现由于不满足硬件的限制条件导致的接入失败。此时，基站侧可通过配置信令，实现外层波束的UE不进行2步RA接入：
位图信令为：11111111111111110000000或者掩码信令为：5。
在此信令配置下，根据实施例一、二三，可实现波束0～15上实现2步RA，在波束15～23上实现4步RA。根据实施例四，可实现波束0～15上实现2步RA，在波束15～23上实现通过预设的RSRP阈值区分2-stepRA和4-stepRA。
在需要根据自身的业务类型和需求选择RA-TYPE时，如图7所示的宽窄波束共覆盖的场景：在相同覆盖区域内，有1层、2层或n层(n>2)波束，以2层波束为例。在图7的第一、二层波束覆盖上，另有一层宽波束，分别为窄波束(0,1)合成宽波束24，窄波束(2,3)合成宽波束25，窄波束(4,5)合成宽波束25，窄波束(5,7)合成宽波束27，窄波束(8,9)合成宽波束28，窄波束(10,11)合成宽波束29，窄波束(12,13)合成宽波束30，窄波束(14,15)合成宽波束31。
此时，基站侧可通过配置信令，实现宽窄波束不同接入方式区分，如宽波束进行2-stepRA接入，窄波束进行4-stepRA接入：
通过如下方式配置信令：位图信令可设为0000000000000000000000011111111或者掩码信令可设为7。
在上述信令配置下，4-stepRA或2-stepRA可供该共覆盖区域中的用户设备选择，在共覆盖区域的用户设备，基于所需传输的数据业务的传输特点，如大小或传输时延要求等，根据实施例一二三通过选择SSB来进一步选择RA-TYPE。在宽波束上进行2-step RA，提高接入速度减少时延，在窄波束上进行4-stepRA，以增强覆盖。
此外，应当理解的是，上面各种方法的步骤划分，只是为了描述清楚，实现时可以合并为一个步骤或者对某些步骤进行拆分，分解为多个步骤，只要包括相同的逻辑关系，都在本专利的保护范围内；对算法中或者流程中添加无关紧要的修改或者引入无关紧要的设计，但不改变其算法和流程的核心设计都在该专利的保护范围内。
本申请第六实施例涉及一种随机接入信道的配置装置，如图8所示，包括：接收模块801、选择模块802、配置模块803。
接收模块801用于接收无线资源管理RRC消息，其中，RRC消息携带SSB与随机接入类型RA-TYPE的关联信息，RA-TYPE包括2步随机接入RA和4步RA。
选择模块802，用于确定待配置的SSB，根据待配置的SSB与RA-TYPE之间的关联信息确定待配置的RA-TYPE。
配置模块803，用于根据由选择模块确定的待配置的SSB和待配置的RA-TYPE完成随机接入信道的配置。
不难发现，本实施例为与第一实施例相对应的装置实施例，本实施例可与第一实施例互相配合实施。第一实施例中提到的相关技术细节在本实施例中依然有效，为了减少重复，这里不再赘述。相应地，本实施例中提到的相关技术细节也可应用在第一实施例中。
值得一提的是，本实施例中所涉及到的各模块均为逻辑模块，在实际应用中，一个逻辑单元可以是一个物理单元，也可以是一个物理单元的一部分，还可以以多个物理单元的组合实现。此外，为了突出本申请的创新部分，本实施例中并没有将与解决本申请所提出的技术问题关系不太密切的单元引入，但这并不表明本实施例中不存在其它的单元。
本申请的第八实施例涉及一种电子设备，如图9所示，包括：至少一个处理器901；以及，与至少一个处理器901通信连接的存储器902；其中，存储器902存储有可被至少一个处理器901执行的指令，指令被至少一个处理器901执行，以使至少一个处理器901能够执行上述任一方法实施例所描述的随机接入信道的配置方法。
其中，存储器902和处理器901采用总线方式连接，总线可以包括任意数量的互联的总线和桥，总线将一个或多个处理器901和存储器902的各种电路连接在一起。总线还可以将诸如外围设备、稳压器和功率管理电路等之类的各种其他电路连接在一起，这些都是本领域所公知的，因此，本文不再对其进行进一步描述。总线接口在总线和收发机之间提供接口。收发机可以是一个元件，也可以是多个元件，比如多个接收器和发送器，提供用于在传输介质上与各种其他装置通信的单元。经处理器901处理的数据通过天线在无线介质上进行传输，进一步，天线还接收数据并将数据传输给处理器901。
处理器901负责管理总线和通常的处理，还可以提供各种功能，包括定时，外围接口，电压调节、电源管理以及其他控制功能。而存储器902可以被用于存储处理器901在执行操作时所使用的数据。
本申请第九实施例涉及一种计算机可读存储介质，存储有计算机程序。计算机程序被处理器执行时实现上述方法实施例。
即，本领域技术人员可以理解，实现上述实施例方法中的全部或部分步骤是可以通过程序来指令相关的硬件来完成，该程序存储在一个存储介质中，包括若干指令用以使得一个设备(可以是单片机，芯片等)或处理器(processor)执行本申请各个实施例所述方法的全部或部分步骤。而前述的存储介质包括：U盘、移动硬盘、只读存储器(ROM，Read-Only Memory)、随机存取存储器(RAM，Random Access Memory)、磁碟或者光盘等各种可以存储程序代码的介质。
本领域的普通技术人员可以理解，上述各实施例是实现本申请的具体实施例，而在实际应用中，可以在形式上和细节上对其作各种改变，而不偏离本申请的精神和范围。
