具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。说明书以及权利要求中“和/或”表示所连接对象的至少其中之一。
参见图1，图1是本公开实施例提供的一种系统信息块的传输系统的结构图，如图1所示，包括用户终端11和基站12，其中，用户终端11可以是UE(User Equipment)，例如：可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端侧设备，需要说明的是，在本公开实施例中并不限定用户终端11的具体类型。上述基站12可以是5G及以后版本的基站(例如：gNB、5G NR NB)，或者其他通信系统中的基站，或者称之为节点B等，需要说明的是，在本公开实施例中仅以5G基站为例，但是并不限定基站12的具体类型。
需要说明的是，上述用户终端11和基站12的具体功能将通过以下多个实施例进行具体描述。
请参见图2，图2是本公开实施例提供的一种系统信息块的传输方法的流程图，该方法应用于基站，如图2所示，包括以下步骤：
步骤201、生成第一系统信息块，其中，所述第一系统信息块包括小区接入相关信息和业务指示信息，所述业务指示信息用于指示所述小区支持的业务类型和所述第一系统信息块的新功能中的至少一项，其中，所述业务类型包括第一协议版本的业务类型，或者包括第一协议版本的业务类型和第二协议版本的业务类型，所述新功能与所述第二协议版本相关。
其中，上述小区接入相关信息可以是，用户终端接入小区时的必要信息，例如：可以包括如下至少一项：
系统帧号(System Frame Number，SFN)、半帧指示(Half frame indicator)、 同步信号块时间序号(SS block time index)，小区禁止接入指示(Cellbarred)、物理下行共享信道(Physical Downlink Shared Channel，PDSCH)第一个解调参考信号(Demodulation Reference Signal，DMRS)位置指示信息、物理资源块网格偏移(PRB grid offset)、下行参数设定(DL numerology)指示信息和控制资源组(control resource set，CORESET)的配置信息，其中，上述Cellbarred用于指示允许终端接入小区，或者禁止终端接入小区；上述CORESET的配置信息可以包含CORESET的时频域位置和剩余最小系统信息(Remaining minimum system information，RMSI)的定时配置信息，上述DL numerology可以包括子载波间隔、符号长度和循环前缀(Cyclic Prefix，CP)长度等参数。
另外，上述第二协议版本为所述第一协议版本的升级版本可以理解为，上述第二协议版本为第一协议版本的后续版本，如上述第一协议版本可以是Rel-15版本，上述第二协议版本可以是Rel-16版本，对此本公开实施例中不作限定，例如：上述第一协议版本可以是Rel-n版本，上述第二协议版本可以是Rel-n+k版本，其中，n可以是大于或者等于15的整数，k可以是大于或者等于1的整数。另外，上述第一协议版本的业务可以是，第一协议版本中支持的业务，例如：Rel-15版本中的eMBB业务，而上述第二协议版本的业务可以是第二协议版本才支持的业务，例如：Rel-16版本中的mMTC业务。
而上述小区可以是发送上述第一系统信息块中的当前小区。
另外，本公开实施例中，第一系统信息块的新功能可以理解为对第一系统信息块的功能做了改进，可以是在所述第一协议版本定义的系统信息块的基础上修改或新增的功能。另外，上述新功能与所述第二协议版本相关可以理解为，该新功能与第二协议版本存在特定关系，该新功能具体是可以按照第二协议版本的解析方式解析第一系统信息块中的参数。例如：对PDSCH第一个DMRS的位置指示信息、PRB grid offset或者CORESET的配置信息修改了解析方式或者新增加了解析方式等等。具体可以是，同一个PDSCH第一个DMRS的位置指示信息、PRB grid offset或者CORESET的配置信息有两种解析方式，即第一系统信息块的功能做了修改或者增加。而步骤201中的第一系统信息块的功能可以是第一系统信息块修改或者增加的功能。且这里的修改或者增加的功能可以应用于第二协议版本，从而通过一个系统信 息块可以实现两个协议版本的功能，以增加通信系统的前向兼容性。
需要说明的是，本公开实施例中，上述业务指示信息用于指示所述小区支持的业务类型和/或所述第一系统信息块的功能可以理解为，该业务指示信息可以是指示这两项中的某一项或者两项，而未指示的可以通过协议定义，或者基站与用户终端预先协商等方式进行确定。
另外，本公开实施例中，第一系统信息块可以是系统信息中任一系统信息块，可选的，为主系统信息块(Master Information Block，MIB)。
步骤202、发送所述第一系统信息块。
其中，上述发送第一信息块可以是通过广播的方式发送，当然，本公开实施例中，对此不作限定，例如：还可以是通过RRC信令或其他专用其他信令发送。
可选的，上述第一系统信息块可以是通过同步信号块(Synchronization Signal Block，SSB)发送。
本公开实施例中，由于上述第一系统信息块是针对第一协议版本和第二协议版本设计的，从而可以实现通信系统的前向兼容性。另外，不同协议版本的用户终端接收到上述第一系统信息块后，可以存在不同的终端行为，例如：所述第一协议版本的用户终端接收到上述第一系统信息块后，可以直接获取用户终端接入小区时需要的信息，而忽略上述业务指示信息，并根据获取的信息确认是否允许接入小区，若不允许接入，而进行小区重选，若允许接入，则进行接入过程。第二协议版本的用户终端接收到上述第一系统信息块后，可以获取到上述业务指示信息，且根据业务指示信息指示的业务选择性地获取用户终端接入小区时需要的信息或者不获取用户终端接入小区时需要的信息。
需要说明的是，本公开实施例中提供的上述方法可以应用于5G系统，但对此不作限定，只要能够实现基本相同的功能，适用于其他通信系统，例如：但是不限于应用6G系统等等。
在本公开实施例中，生成第一系统信息块，其中，所述第一系统信息块包括小区接入相关信息和业务指示信息，所述业务指示信息用于指示所述小区支持的业务类型和所述第一系统信息块的新功能中的至少一项，其中，所 述业务类型包括第一协议版本的业务类型，或者包括第一协议版本的业务类型和第二协议版本的业务类型，所述新功能与所述第二协议版本相关，其中，所述第二协议版本为所述第一协议版本的升级版本；发送所述第一系统信息块。这样能够实现第一系统信息块在通信系统中的前向兼容性。
请参见图3，图3是本公开实施例提供的一种系统信息块的传输方法的流程图，该方法应用于基站，如图3所示，包括以下步骤：
步骤301、生成第一系统信息块，其中，所述第一系统信息块包括小区接入相关信息和业务指示信息，所述业务指示信息用于指示所述小区支持的业务类型和所述第一系统信息块的新功能中的至少一项，其中，所述业务类型包括第一协议版本的业务类型，或者包括第一协议版本的业务类型和第二协议版本的业务类型，所述新功能与所述第二协议版本相关，其中，所述第二协议版本为所述第一协议版本的升级版本。
其中，上述业务指示信息可以通过第一协议版本定义的系统信息块中空闲bit进行指示，这样实现第一系统信息块可以复用第一协议版本的用户终端和第二协议版本的用户终端。
作为另一种可选的实施方式，所述业务指示信息通过K比特指示所述业务类型和所述新功能中的至少一项，其中，所述K为大于或者等于2的整数；或者
所述业务指示信息通过N比特指示所述业务类型，或者通过M比特指示所述新功能，或者通过N比特和M比特分别指示所述业务类型和所述新功能，其中，所述N比特和M比特为不同的比特，且所述N大于或者等于1的整数，所述M为大于或者等于1的整数。
第一种实施方式中，可以理解为，通过相同的K比特指示业务类型或者所述新功能，或者指示业务类型和所述新功能，即K比特可以指示这三种情况。例如：K＝2时，00表示只支持eMBB业务，01表示支持eMBB业务和mMTC业务，10表示上述新功能，11表示支持eMBB业务和mMTC业务，且上述新功能。该方式由于通过相同的比特联合指示，从而可以节约信令开销。
而上述第二种方式，可以理解为，通过不同的比特来指示业务类型和所 述新功能。例如：N＝1时，0表示只支持eMBB业务，1表示支持eMBB业务和mMTC业务，又例如：M＝1，1表示上述新功能，例如：表示对目标参数进行了修改或者新增，0表示不存在上述新功能，例如：不对目标参数进行修改或者新增，又例如：使用两个比特，其中，第1个比特用于指示业务类型，第2个比特用于指示上述新功能。该方式由于通过不同的比特进行指示，从而更加简单明了。另外，需要说明的是，上述N和M可以是不同，当然，在一些实施方式中，也可以相同。
在另一种可选的实施方式中，所述新功能包括：
所述小区接入相关信息中包括的目标参数的新功能；
其中，所述目标参数包括如下一项或者多项：
SS block time index、Cellbarred、PDSCH第一个DMRS位置指示信息、PRB grid offset、下行numerology指示信息和CORESET的配置信息。
其中，上述新功能可以是在所述第一协议版本定义的系统信息块的目标参数的基础上修改或新增的功能。其中，上述修改的功能，可以理解为，将目标参数的功能进行了修改，例如：修改了PDSCH第一个DMRS的位置指示信息的解析方式，具体可以是，第一协议版本中定义的系统信息块中PDSCH第一个DMRS的位置指示信息的解析为时隙内第三或四个符号位置，而现在修改为PDSCH第一个DMRS的位置指示信息的解析为时隙内第一或二个符号位置。而上述新增的功能可以是理解为，在第一协议版本定义的系统信息块中已有的功能之外，新增加另外的功能，例如：在第一协议版本定义的系统信息块中PRB grid offset的解析为第一个偏移位置，而现在针对PRB grid offset新增加另一种的解析方式，该解析为第二偏移位置，即第一系统信息块有两种解析方式，分别解析为第一偏移位置和第二偏移位置。
另外，该实施方式中，上述业务指示信息可以是指示上述目标参数的新功能，即所述第一协议版本定义的系统信息块的目标参数的基础上修改或新增的功能，例如：目标参数复用于所述第一协议版本和所述第二协议版本，该情况下，可以通过两种解析方式解析上述目标参数，即两个解析方式可以共存。又例如：所述目标参数仅用于第二协议版本，该情况下，只允许通过第二协议版本的解析目标参数，即解析方式不共存。或者，上述业务指示信 息可以是指示上述目标参数存在新功能，其具体功能可以是协议中定义或者预设配置给用户终端。
该实施方式中，可以实现在所述第一协议版本定义的系统信息块的基础上修改或新增的功能，从而使得第一系统信息块可以兼容第一协议版本和第二协议版本，以实现通信系统的前向兼容性。
可选的，所述目标参数的新功能包括：
所述目标参数复用于所述第一协议版本和所述第二协议版本；或者
所述目标参数仅用于第二协议版本。
其中，上述目标参数复用于所述第一协议版本和所述第二协议版本可以理解为，第一协议版本的解析方式可以解析目标参数，且第二协议版本的解析方式也可以解析目标参数，且解析结果不冲突。
上述目标参数仅用于第二协议版本可以理解为，第一协议版本的解析方式和第二协议版本的解析方式同时解析上述目标参数时，解析结果是冲突的，从而只允许第二协议版本的用户终端按照第二协议版本的解析方式解析上述目标参数，但这里对基站不作限定。
第二协议版本的用户终端接收到上述第一系统信息块后，若目标参数复用于所述第一协议版本和所述第二协议版本，则获取所述目标参数，并按照所述第二协议版本的解析方式解析所述目标参数，并根据解析结果执行相应操作；若所述目标参数仅用于第二协议版本，则忽略第一系统信息块中的Cellbarred，获取所述目标参数，并按照所述第二协议版本的解析方式解析所述目标参数，并根据解析结果获取RMSI，并根据所述RMSI中包括的Cellbarred确认是否允许接入所述小区。
其中，目标参数复用于所述第一协议版本和所述第二协议版本的情况下，无论目标参数包括或者不包括Cellbarred，第二协议版本的用户终端均可以根据第一系统信息块包括的Cellbarred确认是否允许接入小区。
该实施方式中，可以实现目标参数存在两种情况，一种是解析方式共存，该情况下，上述目标参数适用于第一协议版本的用户终端和第二协议版本的用户终端。另一种情况是，不共存，该情况下，上述目标参数只适用于第二协议版本的用户终端。
另外，上述业务指示信息可以指示上述新功能可以理解为，上述业务指示信息指示上述目标参数存在新功能，例如：指示对上述目标参数进行了覆盖；或者上述业务指示信息指示上述目标参数的具体功能，例如：指示目标参数复用于所述第一协议版本和所述第二协议版本，或者指示目标参数仅用于第二协议版本。
需要说明的是，本公开实施例中，上述目标参数的新功能可以是协议中定义好的，但在该情况下，上述业务指示信息可以指示在复用于所述第一协议版本和所述第二协议版本，或者在仅用于第二协议版本的情况下用户终端的具体行为，例如：复用于所述第一协议版本和所述第二协议版本的情况，则上述业务指示信息可以指示在该情况下，用户终端的行为为：第一协议版本的用户终端按照第一协议版本的解析方式解析目标参数，并根据解析结果执行相应操作，如，根据第一系统信息块的Cellbarred确认是否允许接入小区，以及根据CORESET的配置信息搜索CORESET；第二协议版本的用户终端按照第二协议版本的解析方式解析目标参数，并根据解析结果执行相应操作，如，根据第一系统信息块的Cellbarred确认是否允许接入小区，根据CORESET的配置信息搜索CORESET。
可选的，所述小区接入相关信息包括所述Cellbarred，若所述目标参数仅用于第二协议版本，则所述Cellbarred指示禁止用户终端接入所述小区。从而第二协议版本的用户终端忽略第一系统信息块的Cellbarred，并根据第二协议版本的解析方式解析目标参数，根据解析结果获取RMSI，并根据所述RMSI中包括的Cellbarred确认是否允许接入所述小区。具体可以是，解析上述资源搜索CORESET，并根据解析结果在相应的资源搜索CORESET，并基于在CORESET内搜到的下行控制信息(Downlink Control Information，DCI)调度指示接收RMSI，根据RMSI中的Cellbarred得知是否允许接入小区。
而第一协议版本的用户终端根据所述Cellbarred，确认禁止接入，并重选小区。
该实施方式中，目标参数仅用于第二协议版本时，Cellbarred指示禁止终端接入所述小区。
例如：业务指示信息使用了2个bit，00表示只支持eMBB，01表示支 持eMBB和mMTC，10表示进行CORESET配置信息的覆盖。
基站广播SSB，其中携带第一MIB。第一MIB中Cellbarred设置为允许用户接入小区，业务指示信息指示01。一个Rel16用户终端(例如：mMTC用户)接收SSB并解析第一MIB，发现小区支持mMTC，该用户终端去预设资源上读取针对mMTC业务的第二MIB，并执行后续小区接入操作。而一个Rel15用户终端接收SSB并解析第一MIB，忽略业务指示信息，读取Cellbarred，发现允许接入小区，执行后续小区接入操作。
又例如：业务指示信息使用了2个bit，00表示只支持eMBB，01表示支持eMBB和mMTC，10表示进行CORESET配置信息的覆盖。
基站广播SSB，其中携带第一MIB，第一级MIB中Cellbarred设置为允许用户接入小区，业务指示信息指示00。一个Rel16用户终端(例如：mMTC用户)接收SSB并解析池中MIB，发现小区不支持mMTC，该用户终端重选小区。
当然，上述目标参数的新功能也可以不在协议中定义，通过上述业务指示信息进行指示，用户终端和基站均根据业务指示信息指示的新功能执行相应操作。该指示方式可以更加灵活，以提高系统的灵活性，适应更加业务或者场景需求。
可选的，在发送所述第一系统信息块之后，所述方法还包括：
若所述目标参数复用于所述第一协议版本和所述第二协议版本，则根据所述第一协议版本的解析方式解析所述目标参数的解析结果执行相应操作，和/或，根据所述第二协议版本的解析方式解析所述目标参数的解析结果执行相应操作；或者
所述目标参数仅用于第二协议版本，则根据所述第二协议版本的解析方式解析所述目标参数的解析结果执行相应操作；或者，
所述目标参数仅用于第二协议版本，则根据所述第二协议版本的解析方式解析所述目标参数的解析结果执行相应操作，以及根据所述第一协议版本的解析方式解析所述目标参数的解析结果执行相应操作。
其中，上述根据所述第一协议版本的解析方式解析所述目标参数的解析结果执行相应操作可以是，获取根据所述第一协议版本的解析方式解析所述 目标参数的解析结果，并根据执行该解析结果对应的操作，例如：基站指示发送的SS block的SS block time index高3位，用户终端确定检测的SS block的SS block time index高3位，基站在PDSCH第一个DMRS位置指示信息对应的位置发送DMRS，终端在PDSCH第一个DMRS位置指示信息对应的位置接收DMRS并判断CORESET时域最大跨度是2符号还是3符号，基站通过PRB grid offset指示SSB频域边界和data PRB频域边界间的offset，用户终端根据PRB grid offset确定SSB频域边界和data PRB频域边界间的offset并推导出相应的data PRB index，基站通过下行numerology指示信息指示RMSI/广播OSI/用于初始接入的msg 2和msg 4的子载波间隔(subcarrier spacing,SCS)，用户终端根据下行numerology指示信息确定RMSI/广播OSI/用于初始接入的msg 2和msg 4的SCS，基站在CORESET的配置信息对应的资源上发送CORESET，终端在CORESET的配置信息对应的资源上搜索CORESET。上述根据所述第二协议版本的解析方式解析所述目标参数的解析结果执行相应操作可以是，获取根据所述第二协议版本的解析方式解析所述目标参数的解析结果，并根据执行该解析结果对应的操作，其中，这里的操作可以参见第一协议版本的相应描述，此处不作赘述。
该实施方式中，可以实现基站按照上述资源配置信息的解析方式复用或者不复用执行不同的操作，满足不同用户终端的需求。
下面以目标参数复用于所述第一协议版本和所述第二协议版本，且目标参数包括CORESET配置信息进行举例说明：
假设Rel16对第一MIB中CORESET配置信息进行了重新定义，业务指示信息使用了2个bit，00表示只支持eMBB，01表示支持eMBB和mMTC，10表示进行CORESET配置信息的覆盖。CORESET配置信息复用Rel15和Rel16，例如假设在Rel15中，CORESET配置信息取0001时表示CORESET频域为48RB，和SSB频域中心对齐，时域位于SSB所在slot的符号0；在Rel16中，CORESET配置信息取0001时表示CORESET频域为48RB，和SSB频域中心对齐，时域位于SSB所在slot的符号1。
基站广播SSB，其中携带第一MIB，第一MIB中Cellbarred设置为允许用户接入小区，业务指示信息指示10，第一MIB中CORESET配置信息指示 为0001，基站在SSB所在slot的符号0和1上分别发送了两个频域为48RB时域跨度为1个OFDM符号的CORESET。CORESET配置信息复用Rel15和Rel16，一个Rel 16用户终端接收SSB并解析第一MIB并获得业务指示信息，发现需要进行CORESET配置信息的覆盖，该用户终端按照Rel16解析第一MIB中的CORESET配置信息，根据该解析结果在SSB所在slot的符号1搜索CORESET和进行后续小区接入步骤。一个Rel15用户终端接收SSB并解析一级MIB，按照Rel15解析第一MIB中的CORESET配置信息，根据该解析结果在SSB所在slot的符号0搜索CORESET和进行后续接入步骤。
需要说明的是，上述业务指示信息可以指示第二协议版本的解析方式，其中，第二协议版本的解析方式存在如下两种：
第一种方式，第二协议版本的用户终端根据第一协议版本的解析映射关系(例如：解析表格)解析目标参数，其中，上述业务指示信息具体可以是指示第一协议版本的解析映射关系中的索引，第二协议版本的用户终端直接将该索引在第一版本的解析映射关系中的解析结果作为第一系统系统信息块的解析结果。该实施方式中，可以实现尽量减少用户终端的修改，降低实现成本。
例如：假设Rel16对第一MIB中CORESET配置信息进行了重新定义，业务指示信息使用了6个bit，其中2bit指示支持的业务类型，例如00表示只支持eMBB，01表示支持eMBB和mMTC，10表示支持eMBB和URLLC；4bit指示CORESET配置信息的覆盖(为了方便，在这里可以称为CORESET配置覆盖信息)，用于指示Rel16的解析下如何对第一MIB中携带的CORESET配置信息的解析结果进行覆盖。其Rel16下的解析结果存在多种设计方式，其中一种Rel16下的解析结果指的是使用该CORESET配置覆盖信息对应的Rel15CORSET配置信息覆盖当前第一MIB中携带的CORESET配置信息。假设CORESET配置信息复用Rel15和Rel16。例如在Rel15中，CORESET配置信息取0001时表示CORESET频域为48RB，和SSB频域中心对齐，时域位于SSB所在slot的符号0；CORESET配置信息取0000时表示CORESET频域为48RB，和SSB频域中心对齐，时域位于SSB所在slot的符号1。假设第一MIB中携带的CORESET配置信息为0001，当CORESET 配置覆盖信息的4bit取0000时，该CORESET配置覆盖信息在Rel16下的解析结果表示使用Rel15下CORESET配置信息为0000时的解析结果对第一MIB中CORESET配置信息取0001时Rel15下解析结果进行覆盖。类似的，指示CORESET配置覆盖信息的4bit取0010、0011……时，分别表示使用Rel15下CORESET配置信息为0010、0011……时的解析结果对第一MIB中CORESET配置信息Rel15下的解析结果进行覆盖。
基站广播SSB，其中携带第一MIB，第一MIB中Cellbarred设置为允许用户接入小区，业务指示信息中指示CORESET配置信息覆盖的4bit为0000，且第一MIB中CORESET配置信息指示为0001，基站在SSB所在slot的符号0和1上分别发送了两个频域为48RB时域跨度为1个OFDM符号的CORESET。CORESET配置信息复用Rel15和Rel16，一个Rel 16用户终端接收SSB并解析第一MIB并获得业务指示信息，发现需要进行CORESET配置信息的覆盖，该用户将Rel15对0000的解析结果覆盖第一MIB中的CORESET配置信息，根据该解析结果在SSB所在slot的符号1搜索CORESET和进行后续小区接入步骤。一个Rel15用户终端接收SSB并解析第一MIB，将Rel15对0001的解析结果作为第一MIB中的CORESET配置信息，根据该解析结果在SSB所在slot的符号0搜索CORESET和进行后续接入步骤。
第二种方式，第二协议版本的用户终端根据第二协议版本的解析映射关系(例如：解析表格)解析目标参数。该实施方式中，可以实现不同协议版本配置不同的解析映射关系。
例如：假设Rel16对第一MIB中CORESET配置信息进行了重新定义，业务指示信息使用了6个bit，其中2bit指示支持的业务类型，例如00表示只支持eMBB，01表示支持eMBB和mMTC，10表示支持eMBB和URLLC；4bit指示CORESET配置信息的覆盖(为了方便，在这里可以称为CORESET配置覆盖信息)，CORESET配置覆盖信息的4bit用于指示Rel16下如何对第一MIB中携带的CORESET配置信息的解析结果进行覆盖，其Rel16下的解析结果存在多种设计方式，其中一种Rel16下的解析结果指的是使用该CORESET配置覆盖信息对应的Rel16CORSET配置信息覆盖当前第一MIB中携带的CORESET配置信息。假设CORESET配置信息复用Rel15和Rel16， 例如在Rel15中，CORESET配置信息取0001时表示CORESET频域为48RB，和SSB频域中心对齐，时域位于SSB所在slot的符号0。假设第一MIB中携带的CORESET配置信息为0001，当CORESET配置覆盖信息的4bit取0000时，该CORESET配置覆盖信息在Rel16下的解析结果表示使用Rel16下CORESET配置信息为0000时的解析结果对第一MIB中CORESET配置信息取0001时Rel15下的解析结果进行覆盖，假设Rel16下CORESET配置信息取0000时表示CORESET频域为48RB，和SSB频域中心对齐，时域位于SSB所在slot的符号2。类似的，指示CORESET配置覆盖信息的4bit取0010、0011……时，分别表示使用Rel16下CORESET配置信息为0010、0011……时的解析结果对第一MIB中CORESET配置信息Rel15下的解析结果进行覆盖。
基站广播SSB，其中携带第一MIB，第一MIB中Cellbarred设置为允许用户接入小区，业务指示信息中指示CORESET配置信息覆盖的4bit为0000，且第一MIB中CORESET配置信息指示为0001，基站在SSB所在slot的符号0和1上分别发送了两个频域为48RB时域跨度为1个OFDM符号的CORESET。一个Rel16用户终端接收SSB并解析第一MIB并获得业务指示信息，发现需要进行CORESET配置信息的覆盖，该用户按照Rel16的0000去解析覆盖后的第一MIB中的CORESET配置信息，根据该解析结果在SSB所在slot的符号2搜索CORESET和进行后续小区接入步骤。一个Rel15用户终端接收SSB并解析第一MIB，按照Rel15的0001去解析第一MIB中的CORESET配置信息，根据该解析结果在SSB所在slot的符号0搜索CORESET和进行后续接入步骤。
下面以目标参数仅用于第二协议版本表示进行举例说明：
假设Rel16对第一MIB中CORESET配置信息进行了重新定义，业务指示信息使用了2个bit，00表示只支持eMBB，01表示支持eMBB和mMTC，10表示进行CORESET配置信息的覆盖。目标参数仅用于R16，例如假设在Rel15中，CORESET配置信息取0001时表示CORESET频域为24RB，和SSB频域中心对齐，位于SSB所在slot的符号0和1；在Rel16中，CORESET配置信息取0001时表示CORESET频域为24RB，和SSB频域中心对齐，位于 SSB所在slot的符号1和2。一级MIB中Cellbarred设置为禁止用户接入小区。
基站广播SSB，其中携带第一MIB，第一MIB中Cellbarred设置为禁止用户接入小区，RMSI中的Cellbarred设置为允许用户接入小区，业务指示信息指示10，第一MIB中CORESET配置信息指示为0001。一个Rel16用户终端接收SSB并解析第一MIB，忽略第一MIB中的Cellbarred，并获得业务指示信息，发现需要进行CORESET配置信息的覆盖，该用户按照Rel16去解析第一MIB中的CORESET配置信息，根据该解析结果在SSB所在slot的符号1和2搜索CORESET并基于在CORESET内搜到的DCI调度指示接收RMSI，根据RMSI中的Cellbarred得知允许接入小区。一个Rel15用户终端接收SSB并解析第一MIB，发现第一MIB中的Cellbarred设置为禁止用户接入小区，该用户重选小区。
步骤302、发送所述第一系统信息块。
步骤303、若所述小区支持所述第二协议版本的业务，则在预设资源发送第二系统信息块，其中，所述第二系统信息块与所述第一系统信息块至少部分参数不同，以及所述第二系统信息块包括所述第二协议版本的业务的接入相关信息。
其中，上述预设资源可以协议定义的，或者基站与用户终端预先协商的等等。另外，上述第二系统信息块与所述第一系统信息块至少部分参数不同可以理解为，这两个系统信息块的参数全部不同，或者允许部分参数相同。
上述接入相关信息可以是用户终端接入上述小区进行第二协议版本的业务时的相关信息，例如：用户终端接入上述小区进行第二协议版本的业务所必须的部分最小系统信息，而另一部分最小系统信息可以是通过上述第一系统信息块携带。这样可以实现第一系统信息块给用户终端发送业务指示信息，辅助用户终端快速获取小区支持的业务类型，并联合第二系统信息块中的参数，指示用户终端后续操作，并保证前向兼容性。
例如：在上述业务指示信息至少用于指示所述小区支持的业务类型的情况下，所述第二协议版本的用户终端获取上述业务指示信息后，若所述业务类型不包括所述用户终端期望的业务类型，则进行小区重选；若所述业务类 型包括所述用户终端期望的业务类型，且所述用户终端期望的业务类型存在第二系统信息块，则在预设资源接收所述第二系统信息块。其中，上述用户终端期望的业务类型是否存在第二系统信息块，用户终端可以通过预先配置，或者协议中定义得知，当然，也可以是基站配置给用户终端。其中，上述用户终端期望的业务类型可以是上述用户终端期望的，以及支持的业务类型。
需要说明的是，本实施例中，对步骤302和步骤303的执行顺序不作限定，可以是先执行步骤302，再执行步骤302，或者这两个步骤同时执行，或者也可以是先执行步骤303，再执行步骤302。其中，附图以先执行步骤302，再执行步骤302进行举例说明。另外，上述第一系统信息块和第二系统信息块中的第一和第二仅是为了区分两个系统信息块，并不构成对系统信息块的限定，例如：上述第一系统信息块还可以称作一级系统信息块，第二系统信息块还可以称作二级系统信息块。可选的，上述第一系统信息块和第二系统信息块均可以是MIB。
本实施例中，在图1所示的实施例的基础上增加了发送第二系统信息块，这样可以实现第一系统信息块给用户终端发送业务指示信息，辅助用户终端快速获取小区支持的业务类型，并联合第二系统信息块中的参数，指示用户终端后续操作，并保证前向兼容性。
