具体实施方式
本发明实施例描述的网络架构以及业务场景是为了更加清楚的说明本发明实施例的技术方案，并不构成对于本发明实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本发明实施例提供的技术方案对于类似的技术问题，同样适用。
本发明实施例中，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
图1示出了本发明实施例中一种可能的应用场景示意图。该应用场景中的通信系统包括：网络设备10，以及至少两种类型的终端设备20和30。其中，网络设备和至少两种类型的终端设备可以通过一种或多种空口技术进行通信。
终端设备接入NR网络，需要经过小区搜索，获取系统信息，以及随机接入等过程。终端通过小区的系统信息，获知小区的信息，从而保证接入小区后得以在该小区内正确地工作。终端设备在小区搜索的过程中，需要搜索同步信号块(SS/PBCH Block,SSB)，同步信号块中包含的内容为主同步信号(Primary Synchronization Signal，PSS)，辅同步信号(Secondary Synchronization Signal，SSS)，解调参考信息号(Demodulation reference signal，DMRS)，以及物理广播信道(Physical broadcast channel，PBCH)。UE通过SSB可以获取下行同步，小区物理小区标识(physical-layer cell identity，PCI)，以及小区的新系统信息。
对某一小区来说，该小区的系统信息是对该小区内所有终端设备生效的，可以理解为，系统信息为小区级别。系统信息可分为主信息块(Master Information Block，MIB)和多个系统信息块(System Information Block，SIB)。终端设备在完成SSB解码后，得到MIB信息，MIB信息中包含了用于指示调度SIB1的控制信息配置参数的字段PDCCH-ConfigSIB1。终端设备通过查表的方式，通过PDCCH-ConfigSIB1获得SSB和控制资源集的信息，从而获得物理下行控制信道(Physical Downlink Control Channel，PDCCH)的位置，该PDCCH用于调度物理下行共享信道(Physical Downlink Shared Channel，PDSCH)，终端设备通过解码PDSCH获得SIB1指示的信息。
通过上述描述可以看出，MIB和SIB1为终端设备接入小区必要的信息。由于MIB信息为小区级别的，网络设备通过MIB信息可以指示禁止终端设备接入小区。但现有技术中，当小区中存在两种及两种以上类型的终端设备时，网络设备无法实现只允许某种特定类型的终端设备接入小区，而不允许其他类型的终端设备接入小区。此外，对于有些类型的终端设备来说，可能存在网络设备不具有支持该种终端设备接入能力的情况，此时终端设备盲目尝试接入小区，不仅无法成功接入小区，还会造成电量消耗。
基于上述，本申提供一种接入方法，该方法的原理为，网络设备配置至少一个第一信息，用于指示网络设备是否有能力支持新类型终端设备接入，和/或网络设备是否允许新类型终端设备接入。由此实现当通信系统中存在两种及两种以上类型的终端设备时，能够灵活指示至少两种类型的终端设备的接入信息。
基于终端设备接入小区的过程，以下，对本发明实施例可能出现的名词或者术语进行解释，该名词或者术语也作为发明内容的一部分。
一、主信息块(Master Information Block，MIB)
MIB承载在物理广播信道PBCH中，对某个小区来说，MIB中包含该小区的许多系统信息块的参考及调度信息。MIB消息中承载的是最基本的信息，这些信息涉及到PDSCH信道的解码，终端设备只有先解码MIB，才能利用MIB中的参数去继续解码PDSCH中的数据。现有技术中，MIB信息中存在小区禁止CellBarred字段，用于指示终端设备是否允许接入该小区。MIB信息中还存在1比特的空闲字段Spare，不对任何信息进行指示。
现有协议中，若一个SSB周期内的SSB的数量最大值等于64时，PBCH的字段中有3比特用于指示SSB的索引，当一个SSB周期内的SSB的数量最大值小于64时，PBCH的字段中只用1比特指示SSB的索引，此时存在2比特预留。
二、系统信息块(System Information Block，SIB)
SIB中包含系统消息元素。一个SIB将具有同样性质的系统信息元素组合在一起，不同SIB可以有不同的特征。SIB包含在PDSCH中，该PDSCH由相应的PDCCH调度。
三、物理下行控制信道(Physical Downlink Control Channe，PDCCH)
PDCCH用于承载下行控制信息(Downlink Control Information,DCI)，PDCCH包含一个或者多个控制信道单元(control-channel elements，CCEs)，PDCCH包含的CCE的数目由聚合级别Aggregation level确定。聚合级别和PDCCH包含的CCE的数目可以如表1所示。
表1
聚合级别 CCE的数目
1 1
2 2
4 4
8 8
16 16
四、控制资源集CORESET(Control Resource Set，CORESET)
控制资源集用于表示一个承载PDCCH的时频资源的集合。一个控制资源集由频域上若干个资源块(Resource Block,RB)和时域上若干个符号数组成。一个终端设备可以对应多个控制资源集，而每个控制资源集只能绑定一个CCE到资源单元组(Resource Element Group，REG)映射关系。REG是PDCCH资源映射的基本单位，1个REG定义为1个OFDM符号上的1个RB，一个RB定义为频率上连续的12个子载波和时域上的一个OFDM符号。REG bundle是NR新引入的概念。REG以时间优先映射(Time-First，简称T-F)的方式先组成REG bundle，再以REG bundle为粒度交织或非交织地映射到控制资源上。1个REG bundle由一组在时域和/或频域上连续的REG组成，1个REG bundle大小等于频域上占REG的大小乘以时域上占OFDM符号的大小。
对于MIB信息中的pdcch-ConfigSIB1，不同pdcch-ConfigSIB1状态值对应不同的控制资源集的信息。终端设备通过pdcch-ConfigSIB1，获得PDCCH可能出现的时频范围，通过盲监测的方式，对所有可能出现PDCCH的位置进行检测，直到成功解码PDCCH。
五、网络设备
网络设备可以是基站，或者接入点，或者接入网设备，或者可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。网络设备可用于将收到的空中帧与IP分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)网络。网络设备还可协调对空中接口的属性管理。例如，网络设备可以是全球移动通讯(Global System of Mobile communication，GSM)或码分多址(Code Division Multiple Access，CDMA)中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)中的基站(NodeB，NB)，还可以是长期演进(Long Term Evolution，LTE)中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者中继站或接入点，或者未来5G网络中的基站，例如gNB等，在此并不限定。需要说明的是，对于5G或NR系统，在一个NR基站下，可能存在一个或多个发送接收点(Transmission Reception  Point，TRP)，所有的TRP属于同一个小区，其中，每个TRP和终端都可以使用本申请实施例所述的测量上报方法。在另一种场景下，网络设备还可以分为控制单元(Control Unit，CU)和数据单元(Data Unit，DU)，在一个CU下，可以存在多个DU，其中，每个DU和终端都可以使用本申请实施例所述的测量上报方法。CU-DU分离场景和多TRP场景的区别在于，TRP只是一个射频单元或一个天线设备，而DU中可以实现协议栈功能，例如DU中可以实现物理层功能。
六、终端设备
终端设备可以是无线终端也可以是有线终端，无线终端可以是指向用户提供语音和/或其他业务数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议(Session Initiation Protocol，SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)等设备。无线终端也可以称为系统、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)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device or User Equipment)，在此不作限定。
七、能力降低的(Reduced Capability，REDCAP)终端设备
新无线(New Radio，NR)通信系统中,存在应用场景需要支持REDCAP终端设备。REDCAP终端设备通常具有更窄的带宽、更少的天线端口数、更低的处理能力、更长的处理时间、和/或更低的传输速率等。另外，REDCAP终端设备的电池寿命更长，处理复杂度更低和/或成本也更低。
八、无线网络临时标识(Radio Network Temporary Identifier，RNTI)
RNTI为网络设备配置，用于标识小区中某个连接态的终端设备，寻呼场景下的一组终端设备，和/或一个特殊的无线信道等。不同种类的RNTI的工作原理都是通过加扰无线信道下行控制信息(Downlink Control Information，DCI)的循环冗余校验(Cyclic Redundancy Check,CRC)部分。DCI包含在物理下行控制信道(Physical Downlink Control Channel,PDCCH)。
九、调制和编码策略(Modulation and Coding Scheme，MCS)
MCS调制编码表是802.11n为表征WLAN的通讯速率而提出的一种表示形式。NR的速率匹配通过MCS索引值实现。每一个MCS索引对应一组调制阶数，目标码率，以及频谱效率。MCS索引通过DCI指示。承载SIB1的PDSCH，是通过系统信息(System Information)无线网络临时标识(简称SI-RNTI)加扰的DCI来调度的，此时有一些预留的空闲比特，该空闲比特为15比特或17比特。以下实施例中，用第一字段代表该空闲比特。
在现有协议中，对于通过寻呼无线网络临时标识P-RNTI，随机接入无线网络临时标识RA-RNTI，SI-RNTI加扰的DCI，调制阶数要小于等于2。
DCI中共有5比特用于指示MCS的索引值。MCS索引的指示范围为0至9时，对应的调制阶数为2；MCS索引的指示范围为10至16时，调制阶数为4；MCS索引的指示范围为17至28时，调制阶数为6；MCS索引的指示范围为29、30和31时，调制阶数分别为2、4和6。其中，MCS索引值为0至28时，每个索引值都同时对应一种编码速率和频谱效率，MCS索引值为29至31时，为保留状态，暂时不做任何编码速率和频谱效率的指示。因此对于承载SIB1的PDSCH，调度该PDSCH的DCI。
所指示的调制阶数不超过2时，相应的，MCS的索引值的范围也为0至9，此时，上述指示MCS索引值的5比特字段的状态为0000至01001，此时MCS索引值的指示字段的最高位为0。
十、频率范围(Frequency Range，FR)
频率范围又称频段，在NR系统中，FR1内的频率在410MHz至7125MHz之间，FR2内的频率大于24250MHz。
本申请提供的技术方案可以应用于各种通信系统，如：可以应用于第五代(5th generation mobile networks，5G)通信系统，未来演进系统或多种通信融合系统等中。本申请提供的技术方案可以应用于上述通信系统的多种应用场景中，例如工业无线传感(Industry Wireless Sensor Network，IWSN)和视频监控(Video surveillance)。本申请可以提供的技术方案可以支持多种终端设备类型，例如，REDCAP终端设备。包括，工业无线传感器，视频监控摄像头，可穿戴设备(智能手表)等。
为了使本领域技术人员更好地理解本发明实施例提供的技术方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
图2所示为本申请提供的一种接入信息指示方法的流程示意图。该方法可以由终端设备和网络设备执行，或者也可以由终端设备中的芯片和网络设备中的芯片执行。图2中的网络设备可为上述图1中的接入网设备10，终端设备可为上述图1中的终端设备20。图2所示的方法可包括以下操作。

S202：确定网络设备是否支持第一终端设备接入和/或是否允许第一终端设备接入。
