请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个终端11以及若干个基站12。
其中，终端11可以是指向用户提供语音和/或数据连通性的设备。终端11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，终端11可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)、移动站(mobile  station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment，UE)。或者，终端11也可以是无人飞行器的设备。或者，终端11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，终端11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，MTC系统。
其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站12的具体实现方式不加以限定。
基站12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
本公开实施例涉及的执行主体包括但不限于：采用5G蜂窝移动通信技术进行通信的工业传感器(Industrial sensor)、监控摄像(video surveillance)以及可穿戴类设备等用户设备，以及基站等。
本公开实施例的一种应用场景为：目前，新空口(NR，New Radio)系统设计的最小带宽实际等于剩余关键系统信息(RMSI，Remaining system information)的公共控制资源集(CORESET，Common control resource set)的带宽。在初始接入过程中，用户设备找到同步信号和PBCH块(SSB，Synchronization Signal and PBCH block)的同步信号后读取物理广播信道(PBCH，Physical Broadcast Channel)信息。SSB的带宽是固定的，目前对15k的子载波间隔(SCS，Subcarrier Spacing)是15*12*20＝3.6M。PBCH信息里会指示RMSI的CORESET带宽，UE从RMSI的CORESET找到对应的PDCCH然后再解PDSCH，所以UE需要至少支持PBCH里配置的RMSI的CORESET带宽，目前配置里最大是96个PRB，也就是接近18M，算上保护带宽，UE至少需要支持20M才可以。
工业传感器以及手表等可穿戴5G设备不需要这么大的带宽，只需要10M左右的带宽，但这样就和R15/16的接入流程有了不兼容的地方。
通信网络系统可以对大小带宽用户设备同时支持，但是，这样对运营商和网络规划挑战比较大。有些运营商支持，有些可能不想支持，需要对轻量用户设备的接入进行限制。
如图2所示，本示例性实施例提供一种于接入控制方法，可以应用于无线通信的基站中，接入控制方法可以包括：
步骤201：发送携带有接入指示信息的SSB的PBCH信息，其中，接入指示信息用于指示是否允许第一类型用户设备接入，其中，第一类型用户设备的最大工作带宽小于第二类型用户设备的工作带宽。
第一类型用户设备可以包括但不限于：3GPP R17版本协议中的轻量用户设备。第二类型用户设备可以是eMBB用户设备。第一类型用户设备支持的最大带宽小于eMBB要求用户设备支持的最小带宽。例如，第一类型用户设备支持的最大带宽小于第二类型用户设备的工作带宽：100M。
基站可以通过广播等形式发送接入指示信息，接入指示信息用于指示第一类型用户设备是否允许接入。接入指示信息可以携带在现有的广播信息中，如SSB的PBCH信息等信息中。基站可以针对所有频点采用相同的接入规则，即在所有频点均不允许第一类型用户设备接入；也可以针对所有不同频点采用不同的接入规则，即在部分频点均允许第一类型用户设备接入，在部分频点均不允许第一类型用户设备接入。这里，接入可以是指用户设备初始接入基站，也可以是从服务小区接入邻小区等。
可以利用PBCH信息的预留比特位设置接入指示信息。还可以利用PBCH信息的冗余码点作为指示信息。这里，冗余码点可以是PBCH信息中未定义的指示含义的比特值或比特序列值。示例性的，PBCH信息中包括的4个比特位，其中，“1111”被定义为某一配置，而“1110”和“1100”未被定义，则可以将“1110”和“1100”两个值分别定义为允许第一类型用户设备接入和不允许第一类型用户设备接入。
用户设备根据接收到的接入指示信息，确定基站的接入限制。如果接入指示信息指示不允许第一类型用户设备接入，则不进行接入，继续搜索其他基站或频点。如果接入指示信息指示基站允许第一类型用户设备接入，则进行接入。
由于轻量用户设备的带宽不同于eMBB用户设备的带宽，基站支持轻量用户设备会增加基站配置的复杂程度，通常基站都不对轻量用户设备的 带宽进行配置。因此，针对不配置轻量用户设备带宽的基站可以在PBCH信息中携带接入指示信息，减少轻量用户设备的接入尝试。在配置有轻量用户设备带宽的基站中，为合理分配资源，在资源不足的情况下，也可以不允许轻量用户设备，以集中资源分配给eMBB用户设备。
基站可以根据自身的带宽配置情况，确定是否允许第一类型用户设备接入。当基站配置第一类型用户设备支持的带宽时，可以允许第一类型用户设备接入。当基站未配置第一类型用户设备支持的带宽时，可以配置接入指示信息指示不允许第一类型用户设备接入。这里，带宽配置可以包括用户设备接入后的通信带宽。
基站还可以结合自身的通信负载等状态，确定是否允许第一类型用户设备接入。当基站配置第一类型用户设备支持的带宽，并且基站的通信负载小于或等于预定阈值时，基站可以配置接入指示信息指示允许第一类型用户设备接入。当基站配置第一类型用户设备支持的带宽，并且基站的通信负载大于预定阈值时，基站可以配置接入指示信息指示不允许第一类型用户设备接入。
如此，一方面，基站通过接入指示信息，指示第一类型用户设备是否可以进行接入，可以方便对接入的用户设备类型进行控制，进而提高基站对不同用户设备的兼容。另一方面，第一类型用户设备根据该显性的指示信息，可以在尝试接入前确定是否可以接入，减少了无效的接入尝试，提高通信效率，节省通信资源。
在一个实施例中，PBCH信息中MIB域的空闲预留比特位中携带有接入指示信息。
接入指示信息可以携带在PBCH信息中，基站利用PBCH中MIB域的空闲预留比特位(Spare bit)指示是否允许第一类型用户设备接入进行指示。这里，空闲预留比特位可以是MIB域中未定义指示含义并且未被占用的比特位。
如图3所示的PBCH信息帧结构示意图中，接入指示信息可以设置在PBCH中MIB域的空闲预留比特位中。
示例性的，基站可以利用MIB域中的一个空闲预留比特位携带接入指示信息。可以用“0”表示不允许第一类型用户设备接入，用“1”表示允许第一类型用户设备接入；也可以用“1”表示不允许第一类型用户设备接入，用“0”表示允许第一类型用户设备接入。
第一类型用户设备接收到广播的PBCH信息后，根据读取的PBCH信息中MIB域的空闲预留比特位中的接入指示信息，确定接入限制。如果基站不允许第一类型用户设备接入当前小区或频点，则停止搜索该频点的SSB，即不进行接入，继续搜索其他频点。如果基站允许第一类型用户设备接入，则进行接入。
在一个实施例中，PBCH信息中有效载荷域的预留比特位中携带有接入指示信息。
接入指示信息可以携带在PBCH信息中，基站利用PBCH中有效载荷域的预留比特位对是否允许第一类型用户设备接入进行指示。
如图3所示的PBCH信息帧结构示意图中，接入指示信息可以设置在PBCH有效载荷域的预留比特位中。
示例性的，基站可以利用有效载荷域中的一个比特位携带接入指示信息。可以用“0”表示不允许第一类型用户设备接入，用“1”表示允许第一类型用户设备接入；也可以用“1”表示不允许第一类型用户设备接入，用“0”表示允许第一类型用户设备接入。
第一类型用户设备接收到广播的PBCH信息后，根据读取的PBCH信息中有效载荷域的预留比特位中的接入指示信息，确定接入限制。如果基站不允许第一类型用户设备接入当前小区或频点，不进行接入，继续搜索其他频点。如果基站允许第一类型用户设备接入，则进行接入。第一类型用户设备在确定基站不允许第一类型用户设备接入当前小区或频点，第一类型用户设备可以搜索其他小区或频点的SSB，并尝试接入。如此，可以在第一类型用户设备解析SSB的初期确定当前小区或频点是否可以接入，减少不必要的接入尝试。
在一个实施例中，PBCH信息中有效载荷域的预留比特位中携带有接入 指示信息，包括：有效载荷域的最低比特位和/或次低比特位中携带有接入指示信息。
这里，如图3，最低比特位可以是有效载荷A+7位置的比特位，次低比特位可以是有效载荷A+6位置的比特位。可以采用有效载荷A+6位置的比特位和A+7位置的比特位中任一比特位设置接入指示信息；也可以采用有效载荷A+6和A+7位置的两个比特位设置接入指示信息。
在一个实施例中，PBCH信息中还携带有指示RMSI的CORESET带宽的带宽信息；
带宽信息及接入指示信息，共同用于供第一类型用户设备确定是否允许接入。
这里，基站的PBCH信息中的RMSI的CORESET的带宽信息用于指示RMSI的CORESET的带宽。第一类型用户设备可以根据带宽信息确定RMSI的CORESET的带宽和第一类型用户设备支持的带宽是否匹配，进而判断是否进行接入。
RMSI的CORESET的带宽可以与基站配置的用户设备接入后的通信带宽相同，也可以不同。
第一类型用户设备可以结合带宽信息和接入指示信息确定是否进行接入。例如，基站可以在带宽信息中配置RMSI的CORESET的带宽小于或定第一类型用户设备支持的最大带宽，如此，第一类型用户设备可以接入。在通信负载较高的情况下，基站可以通过接入指示信息指不允许第一类型用户设备接入，以此减少新接入的第一类型用户设备，降低通信负载。
第一类型用户设备可以根据带宽信息的指示和接入指示信息的指示的逻辑处理结果，确定是否进行接入。也可以为带宽信息的指示和接入指示信息的指示设置优先级，根据优先级高的指示。确定是否进行接入。
基站可以在带宽信息中配置RMSI的CORESET的带宽小于或定第一类型用户设备支持的最大带宽。同时，发送接入指示信息显性指示第一类型用户设备可以接入。如此，当第一类型用户设备接收到PBCH信息，并确定第一类型用户设备支持RMSI的CORESET的带宽，如果支持，并且接入 指示信息指示第一类型用户设备可以接入，则进行接入。
基站可以在带宽信息中配置RMSI的CORESET的带宽大于第一类型用户设备支持的最大带宽，如此，第一类型用户设备无法接收RMSI的CORESET，隐含指示第一类型用户设备不可以接入。此时，无论接入指示信息指示是否允许第一类型用户设备接入，第一类型用户设备均无法进行接入。
基站和用户设备可以约定接入指示信息的指示具有较高优先级。当带宽信息隐含指示第一类型用户设备可以接入，但接入指示信息指示不允许第一类型用户设备接入，由于接入指示信息具有较高优先级，因此，用户设备将不进行接入。
如图4所示，本示例性实施例提供一种于接入控制方法，可以应用于无线通信的用户设备中，接入控制方法可以包括：
步骤401：接收携带有接入指示信息的SSB的PBCH信息；
步骤402：根据接入指示信息的指示，确定是否进行接入；其中，第一类型用户设备的最大工作带宽小于第二类型用户设备的工作带宽。
第一类型用户设备可以包括但不限于：3GPP R17版本协议中的轻量用户设备。第二类型用户设备可以是eMBB用户设备。第一类型用户设备支持的最大带宽小于eMBB要求用户设备支持的最小带宽。例如，第一类型用户设备支持的最大带宽小于第二类型用户设备的工作带宽：100M。
基站可以通过广播等形式发送接入指示信息，接入指示信息用于指示第一类型用户设备是否允许接入。接入指示信息可以携带在现有的广播信息中，如SSB的PBCH信息等信息中。基站可以针对所有频点采用相同的接入规则，即在所有频点均不允许第一类型用户设备接入；也可以针对所有不同频点采用不同的接入规则，即在部分频点均允许第一类型用户设备接入，在部分频点均不允许第一类型用户设备接入。这里，接入可以是指用户设备初始接入基站，也可以是从服务小区接入邻小区等。
可以利用PBCH信息的预留比特位设置接入指示信息。还可以利用PBCH信息的冗余码点作为指示信息。这里，冗余码点可以是PBCH信息 中未定义的指示含义的比特值或比特序列值信息；示例性的，PBCH信息中包括的4个比特位，其中，“1111”被定义为某一配置，而“1110”和“1100”未被定义，则可以将“1110”和“1100”两个值分别定义为允许第一类型用户设备接入和不允许第一类型用户设备接入。
用户设备根据接收到的接入指示信息，确定基站的接入限制。如果接入指示信息指示基站不允许第一类型用户设备接入当前小区或频点，则不进行接入，继续搜索其他基站或频点。如果接入指示信息指示基站允许第一类型用户设备接入，则进行接入。
由于轻量用户设备的带宽不同于eMBB用户设备的带宽，基站支持轻量用户设备会增加基站配置的复杂程度，通常基站都不对轻量用户设备的带宽进行配置。因此，针对不配置轻量用户设备带宽的基站可以在PBCH信息中携带接入指示信息，减少轻量用户设备的接入尝试。在配置有轻量用户设备带宽的基站中，为合理分配资源，在资源不足的情况下，也可以不允许轻量用户设备，以集中资源分配给eMBB用户设备。
基站可以根据自身的带宽配置情况，确定是否允许第一类型用户设备接入。当基站配置第一类型用户设备支持的带宽时，可以允许第一类型用户设备接入。当基站未配置第一类型用户设备支持的带宽时，可以配置接入指示信息指示不允许第一类型用户设备接入。这里，带宽配置可以包括用户设备接入后的通信带宽。
基站还可以结合自身的通信负载等状态，确定是否允许第一类型用户设备接入。当基站配置第一类型用户设备支持的带宽，并且基站的通信负载小于或等于预定阈值时，基站可以配置接入指示信息指示允许第一类型用户设备接入。当基站配置第一类型用户设备支持的带宽，并且基站的通信负载大于预定阈值时，基站可以配置接入指示信息指示不允许第一类型用户设备接入。
如此，一方面，基站通过接入指示信息，指示第一类型用户设备是否可以进行接入，可以方便对接入的用户设备类型进行控制，进而提高基站对不同用户设备的兼容。另一方面，第一类型用户设备根据该显性的指示 信息，可以在尝试接入前确定是否可以接入，减少了无效的接入尝试，提高通信效率，节省通信资源。
在一个实施例中，步骤402可以包括：响应于接入指示信息指示允许第一类型用户设备接入，确定进行接入。
用户设备根据接收到的接入指示信息，确定基站的接入限制。如果接入指示信息指示基站允许第一类型用户设备接入，则进行接入。
在一个实施例中，步骤402可以包括：响应于接入指示信息指示不允许第一类型用户设备接入，确定不进行接入。
用户设备根据接收到的接入指示信息，确定基站的接入限制。如果接入指示信息指示基站不允许第一类型用户设备接入当前小区或频点，则不进行接入，继续搜索其他小区或频点。
在一个实施例中，接入控制方法还可以包括：搜索第一频点的SSB，其中，所述第一频点的不同于第一类型用户设备当前所在的第二频点。
第一类型用户设备在确定基站不允许第一类型用户设备接入当前小区或频点，第一类型用户设备可以搜索其他小区或频点的SSB，并尝试接入。如此，可以在第一类型用户设备解析SSB的初期确定当前小区或频点是否可以接入，减少不必要的接入尝试。
在一个实施例中，PBCH信息中MIB域的空闲预留比特位中携带有接入指示信息。
接入指示信息可以携带在PBCH信息中，基站利用PBCH中MIB域的空闲预留比特位(Spare bit)指示是否允许第一类型用户设备接入进行指示。
如图3所示的PBCH信息帧结构示意图中，接入指示信息可以设置在PBCH中MIB域的空闲预留比特位中。
示例性的，基站可以利用MIB域中的一个空闲预留比特位携带接入指示信息。可以用“0”表示不允许第一类型用户设备接入，用“1”表示允许第一类型用户设备接入；也可以用“1”表示不允许第一类型用户设备接入，用“0”表示允许第一类型用户设备接入。
第一类型用户设备接收到广播的PBCH信息后，根据读取的PBCH信 息中MIB域的空闲预留比特位中的接入指示信息，确定接入限制。如果基站不允许第一类型用户设备接入，则停止搜索该频点的SSB，即不进行接入，继续搜索其他频点。如果基站允许第一类型用户设备接入，则进行接入。
在一个实施例中，PBCH信息中有效载荷域的预留比特位中携带有接入指示信息。
接入指示信息可以携带在PBCH信息中，基站利用PBCH中有效载荷域的预留比特位对是否允许第一类型用户设备接入进行指示。这里，空闲预留比特位可以是MIB域中未定义指示含义并且未被占用的比特位。
如图3所示的PBCH信息帧结构示意图中，接入指示信息可以设置在PBCH有效载荷域的预留比特位中。
示例性的，基站可以利用有效载荷域中的一个比特位携带接入指示信息。可以用“0”表示不允许第一类型用户设备接入，用“1”表示允许第一类型用户设备接入；也可以用“1”表示不允许第一类型用户设备接入，用“0”表示允许第一类型用户设备接入。
第一类型用户设备接收到广播的PBCH信息后，根据读取的PBCH信息中有效载荷域的预留比特位中的接入指示信息，确定接入限制。如果基站不允许第一类型用户设备接入，不进行接入，继续搜索其他频点。如果基站允许第一类型用户设备接入，则进行接入。
在一个实施例中，PBCH信息中有效载荷域的预留比特位中携带有接入指示信息，包括：有效载荷域的最低比特位和/或次低比特位中携带有接入指示信息。
这里，如图3，最低比特位可以是有效载荷A+7位置的比特位，次低比特位可以是有效载荷A+6位置的比特位。可以采用有效载荷A+6位置的比特位和A+7位置的比特位中任一比特位设置接入指示信息；也可以采用有效载荷A+6和A+7位置的两个比特位设置接入指示信息。
在一个实施例中，PBCH信息中携带有指示RMSI的CORESET带宽的带宽信息；
步骤402可以包括：结合接入指示信息和带宽信息，确定是否进行接入。
这里，基站的PBCH信息中的RMSI的CORESET的带宽信息用于指示RMSI的CORESET的带宽。第一类型用户设备可以根据带宽信息确定RMSI的CORESET的带宽和第一类型用户设备支持的带宽是否匹配，进而判断是否进行接入。
RMSI的CORESET的带宽可以与基站配置的用户设备接入后的通信带宽相同，也可以不同。
第一类型用户设备可以结合带宽信息和接入指示信息确定是否进行接入。例如，基站可以在带宽信息中配置RMSI的CORESET的带宽小于或定第一类型用户设备支持的最大带宽，如此，第一类型用户设备可以接入。在通信负载较高的情况下，基站可以通过接入指示信息指不允许第一类型用户设备接入，以此减少新接入的第一类型用户设备，降低通信负载。
在一个实施例中，结合接入指示信息和带宽信息，确定是否进行接入，包括以下之一：
响应于第一类型用户设备支持带宽信息指示的带宽，并且接入指示信息指示允许第一类型用户设备接入，确定进行接入；
响应于第一类型用户设备支持带宽信息指示的带宽，并且接入指示信息指示不允许第一类型用户设备接入，确定不进行接入；

响应于第一类型用户设备不支持带宽信息指示的带宽，并且接入指示信息指示不允许第一类型用户设备接入，确定不进行接入。
第一类型用户设备可以根据带宽信息的指示和接入指示信息的指示的逻辑处理结果，确定是否进行接入。也可以为带宽信息的指示和接入指示信息的指示设置优先级，根据优先级高的指示。确定是否进行接入。
基站可以在带宽信息中配置RMSI的CORESET的带宽小于或定第一类型用户设备支持的最大带宽。同时，发送接入指示信息显性指示第一类型 用户设备可以接入。如此，当第一类型用户设备接收到PBCH信息，并确定第一类型用户设备支持RMSI的CORESET的带宽，如果支持，并且接入指示信息指示第一类型用户设备可以接入，则接入流程。
基站可以在带宽信息中配置RMSI的CORESET的带宽大于第一类型用户设备支持的最大带宽，如此，第一类型用户设备无法接收RMSI的CORESET，隐含指示第一类型用户设备不可以接入。此时，无论接入指示信息指示是否允许第一类型用户设备接入，第一类型用户设备均无法进行接入。
基站和用户设备可以约定接入指示信息的指示具有较高优先级。当带宽信息隐含指示第一类型用户设备可以接入，但接入指示信息指示不允许第一类型用户设备接入，由于接入指示信息具有较高优先级，因此，用户设备将不进行接入。
以下结合上述任意实施例提供一个具体示例：
基站用于指示轻量用户设备(REDCAP UE)的方法包括但不限于以下两种：
方法1：占用空闲预留比特位(spare bit)。
基站利用PBCH里的空闲预留比特位，当配置空闲预留比特位为0时，允许轻量用户设备接入，当空闲预留比特位为1时候，不允许轻量用户设备接入；或者，当配置空闲预留比特位为1时，允许轻量用户设备接入，当空闲预留比特位为0时候，不允许轻量用户设备接入
用户设备根据读取的PBCH里的spare bit的信息，确定接入限制。如果不允许接入，则停止搜索该频点的SSB，继续搜索其他的。如果允许接入，则继续初始接入过程。
方法2：对FR1，采用PBCH里的A+6/A+7之一的保留比特位。
用户设备根据读取的PBCH里的保留比特位，确定接入限制。如果不允许接入，继续搜索其他的频点。如果允许接入，则继续初始接入过程。
基站用于指示轻量用户设备的方法还可以包括：假设轻量用户设备支持的最大带宽为n，那么可以通过基站配置超过这个值的RMSI CORESET 带宽来隐含指示，即配置RMSI CORESET带宽为m，其中m>n；
如果基站配置了适合轻量用户设备接入的带宽，那么基站可以通过空闲预留比特位等显性指示来明确告知是否限制轻量用户设备接入。
