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：若干个用户设备110以及若干个基站120。
其中，用户设备110可以是指向用户提供语音和/或数据连通性的设备。用户设备110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，用户设备110可以是物联网用户设备，如传感器设备、移动电话和具有物联网用户设备的计算机，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、远程用户设备(remote terminal)、接入用户设备(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户设备(user equipment)。或者，用户设备110也可以是无人飞行器的设备。或者，用户设备110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用户设备。或者，用户设备110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120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)。
其中，基站120可以是4G系统中采用的演进型基站(eNB)。或者，基站120也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站120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120的具体实现方式不加以限定。
基站120和用户设备110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。

为了便于本领域内技术人员理解，本公开实施例列举了多个实施方式以对本公开实施例的技术方案进行清晰地说明。当然，本领域内技术人员可以理解，本公开实施例提供的多个实施例，可以被单独执行，也可以与本公开实施例中其他实施例的方法结合后一起被执行，还可以单独或结合后与其他相关技术中的一些方法一起被执行；本公开实施例并不对此作出限定。
为了更好地理解本公开任一个实施例所描述的技术方案，首先，对相关技术中终端接入网络的场景进行说明：
在一个实施例中，基站向终端发送指示信息，该指示信息用于指示Redcap终端是否可以驻留在小区或者频率上。这里，该指示信息可以是根据终端的天线数量确定的。
在一个实施例中，指明一种终端类型的定义，包括Redcap终端识别的能力、限制这些Redcap能力仅用于RedCap终端和防止RedCap终端使用不属于RedCap终端的能力。这里，不属于RedCap终 端的能力，至少包括载波聚合、双连接性和更宽的带宽。
在一个实施例中，不允许单天线的终端接入网络。这里，网络配置不允许单天线的终端接入网络。
在一个实施例中，给Redcap终端定义最小物理层能力集合，例如，指示单天线和20MHz带宽的物理层能力集合，网络允许具有最小物理层能力集合指示的终端能力的Redcap终端接入网络。在一个实施例中，在无线资源控制(RRC，Radio Resource control)连接建立后，终端需要上报更多的终端能力。
如图2所示，本实施例中提供一种终端能力信息的上报方法，其中，该方法由终端执行，该方法，包括：
步骤21、在随机接入过程中，向基站发送终端能力信息；
其中，终端能力信息，用于指示终端支持的终端能力。
这里，该终端可以是但不限于是手机、可穿戴设备、车载终端、路侧单元(RSU，Road Side Unit)、智能家居终端、工业用传感设备和/或医疗设备等。这里，终端可以是Redcap终端。
这里，不同类型的终端可以支持不同的终端能力。这里，终端能力可以是终端接入层能力。在一个实施例中，终端支持的终端能力可以通过天线数量和不同的通信带宽等参数进行指示。例如，终端为指示支持1个天线和20Mhz通信带宽的Redcap终端。这里，需要说明的是，终端支持的的终端能力可以通过多次上报时机上报。每次可以上报全部终端能力中的部分终端能力。例如，终端支持的全部终端能力为支持2个天线和40Mhz通信带宽，则终端在第一次上报终端能力时，可以先上报支持1个天线和20Mhz通信带宽的终端能力，在第二次上报终端能力时，再上报支持2个天线和40Mhz通信带宽的终端能力。
在一个实施例中，响应于基站接收到终端能力信息，根据该终端能力信息确定终端是否能够驻留在该基站对应的小区内。例如，可以是不允许只支持单天线的终端能力的终端接入网络。在一个实施例中，基站向终端发送指示信息，该指示信息用于指示终端是否可以驻留在小区上。这里，该指示信息可以是根据终端的天线数量和/或通信带宽确定的。终端在接收到该指示信息后就可以确定是否能够驻留在小区上。
在一个实施例中，可以是利用随机接入过程中的随机接入消息向基站发送终端能力信息。这里，随机接入消息可以包括以下至少之一：消息1Msg1、消息3Msg3和消息5Msg5。这里，可以是利用一个随机接入消息向基站发送全部终端能力的终端能力信息，例如，利用Msg1向基站发送全部终端能力的终端能力信息。这里，还可以是利用多个随机接入消息向基站发送全部终端能力的终端能力信息。例如，利用Msg1向基站发送一部分终端能力的终端能力信息，利用Msg3向基站发送另一部分终端能力的终端能力信息。
在一个实施例中，随机接入消息中携带终端能力信息。例如，随机接入消息直接携带终端的天线数量和通信带宽信息。这里，可以是通过预设字段指示该天线数量和通信带宽的信息。例如，该预设字段可以指示终端的天线为2个，通信带宽为40Mhz。如此，基站在接收到该随机接入消息后，就可以确定终端的终端能力。
在一个实施例中，随机接入消息为Msg1，终端利用PRACH资源发送随机接入消息，这里，PRACH资源可以是随机接入前导码和传输机会RO等。终端在发送Msg1前，根据终端类型确定Prach资源；这里，终端类型可以指示终端支持的终端能力。基站在接收到利用PRACH资源发送的Msg1后，就可以根据Msg1的PRACH资源确定终端的终端类型，并根据终端类型确定终端的终端能力。例如，若终端为Redcap终端类型，终端能力为1个天线和20Mhz，则Msg1利用第一PRACH资源发送，基站在接收到Msg1后根据第一PRACH资源确定终端为Redcap终端类型，则确定终端能力为支持1个天线和20Mhz。
在一个实施例中，PRACH资源，包括以下至少之一：随机接入前导码和传输机会RO。
在一个实施例中，终端类型包括能力缩减Redcap终端类型。
在一个实施例中，终端能力信息，指示至少一个预定的最小终端能力集合；最小终端能力集合，包含至少一个第一终端能力参数。这里，终端和基站可以预先获得最小终端能力集合包含的至少一个第一终端能力参数。
在一个实施例中，第一终端能力参数，包括以下至少之一：天线数量和带宽。
在一个实施例中，在终端利用Msg1发送指示最小终端能力集合的终端能力信息后，终端还可以利用Msg2和Msg3发送更多的终端能力。例如，最小终端能力集合包含的第一终端能力参数为第一天线数量和第一带宽，这里，第一天线数量为1，第一带宽为20Mhz。终端还可以利用Msg5发送第二天线数量和第二带宽，这里，第一天线数量为2，第二带宽为40Mhz。
在一个实施例中，如果已经基于随机接入消息发送了第一终端能力信息，则利用终端能力上报消息向基站发送的终端能力信息可以不包含第一终端能力信息。这里，利用终端能力上报消息向基站发送的终端能力信息可以是第一终端能力信息之外的第二终端能力信息。
在本公开实施例中，在随机接入过程中，向基站发送终端能力信息；其中，终端能力信息，用于指示终端支持的终端能力。这里，首先，由于基站可以获得终端的终端能力信息，因此，可以基于终端能力信息确定是否允许终端接入网络。其次，由于在随机接入过程中，基站就可以获得终端的终端能力信息，相较于需要通过终端能力上报消息的方式获得终端能力信息，能够提前获得终端能力信息且能够减少信令开销。
需要说明的是，本领域内技术人员可以理解，本公开实施例提供的方法，可以被单独执行，也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。
如图3所示，本实施例中提供一种终端能力信息的上报方法，其中，该方法由终端执行，该方法，包括：
步骤31、向基站发送指示终端能力信息的随机接入消息。
在一个实施例中，随机接入消息可以包括以下至少之一：Msg1、Msg3和Msg5。
在一个实施例中，在随机接入过程中只利用一个随机接入消息发送终端能力信息。
在一个实施例中，可以是利用一个随机接入消息向基站发送全部终端能力的终端能力信息，例如，利用Msg1向基站发送全部终端能力的终端能力信息。这里，该终端能力信息可以是预先确定的。
在一个实施例中，在随机接入过程中利用多个随机接入消息发送终端能力信息。
在一个实施例中，可以是利用多个随机接入消息向基站发送全部终端能力的终端能力信息。例如，利用Msg1向基站发送一部分终端能力的终端能力信息，利用Msg3向基站发送另一部分终端能力的终端能力信息。这里，Msg1发送的终端能力信息，指示至少一个预定的最小终端能力集合；最小终端能力集合，包含至少一个第一终端能力参数。这里，终端和基站可以预先获得最小终端能力集合包含的至少一个第一终端能力参数。
需要说明的是，本领域内技术人员可以理解，本公开实施例提供的方法，可以被单独执行，也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。
如图4所示，本实施例中提供一种终端能力信息的上报方法，其中，该方法由终端执行，该方法，包括：
步骤41、基于物理随机接入信道PRACH资源向基站发送随机接入消息；
其中，PRACH资源是根据终端的终端类型确定的，终端类型用于指示终端支持的终端能力。
在一个实施例中，PRACH资源，包括以下至少之一：随机接入前导码和传输机会(RO，transmission occasion)。
在一个实施例中，分配给不同终端类型的终端的PRACH资源不同。
在一个实施例中，根据第一终端类型确定的PRACH资源为第一PRACH资源；根据第二终端类型确定的PRACH资源为第二PRACH资源。若基站接收到终端利用第一PRACH资源发送的随机接入消息，就可以确定终端为第一类型终端；若基站接收到利用第二PRACH资源发送的随机接入消息，就可以确定终端为第二类型终端。
在一个实施例中，随机接入消息为Msg1，终端利用PRACH资源发送随机接入消息，这里，PRACH资源可以是随机接入前导码和传输机会RO等。终端在发送Msg1前，根据终端类型确定Prach资源；这里，终端类型可以指示终端支持的终端能力。基站在接收到利用PRACH资源发送的Msg1后，就可以根据Msg1的PRACH资源确定终端的终端类型，并根据终端类型确定终端的终端能力。例如，若终端为Redcap终端类型，终端能力为1个天线和20Mhz，则Msg1利用第一PRACH资源发送，基站在接收到Msg1后根据第一PRACH资源确定终端为Redcap终端类型，则确定终端能力为支持1个天线和20Mhz。
需要说明的是，本领域内技术人员可以理解，本公开实施例提供的方法，可以被单独执行，也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。
在一个实施例中，终端能力信息，用于指示至少一个预定的最小终端能力集合，最小终端能力集合包含至少一个第一终端能力参数。
这里，终端和基站可以预先确定最小终端能力集合包含的至少一个第一终端能力参数。
在一个实施例中，第一终端能力参数，包括以下至少之一：天线数量和带宽。
例如，最小终端能力集合包含1个天线和20Mhz的参数；或者，最小终端能力集合包含2个天线 和20Mhz的参数；或者，最小终端能力集合包含1个天线和40Mhz的参数。
需要说明的是，本领域内技术人员可以理解，本公开实施例提供的方法，可以被单独执行，也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。
如图5所示，本实施例中提供一种终端能力信息的上报方法，其中，该方法由终端执行，该方法，包括：
步骤51、确定已基于随机接入消息发送终端能力信息且RRC连接建立；
向基站发送第一终端能力上报消息；
其中，第一终端能力上报消息不携带最小终端能力集合指示的第一终端能力参数，或者，所述第一终端能力上报消息携带第二终端能力参数，所述第二终端能力参数为所述最小终端能力集合指示的第一终端能力参数之外的参数。
在一个实施例中，可以是在建立无线资源控制(RRC，Radio Resource Control)连接后，向基站发送第一终端能力上报消息。
在一个实施例中，接收基站发送的指示信息；其中，指示信息，用于指示：基站已基于随机接入消息获得终端能力信息。响应于接收到该指示信息，确定已基于随机接入消息发送终端能力信息。
在一个实施例中，第一终端能力参数和/或第二终端能力参数，包括以下至少之一：天线数量和带宽。
例如，最小终端能力集合指示天线数量为1且通信带宽为20Mhz；第二终端能力参数的值可以是天线数量为2且通信带宽为40Mhz。
这里，由于第一终端能力上报消息在利用随机接入消息发送指示最小终端能力集合的终端能力信息后，不再需要利用第一终端能力上报消息发送指示最小终端能力集合的终端能力信息，如此，可以节省信令开销。
需要说明的是，本领域内技术人员可以理解，本公开实施例提供的方法，可以被单独执行，也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。
如图6所示，本实施例中提供一种终端能力信息的上报方法，其中，该方法由终端执行，该方法，包括：
步骤61、接收基站发送的指示信息，指示信息，用于指示：基站获得终端能力信息。
在一个实施例中，接收基站发送的指示信息；其中，指示信息，用于指示：基站已基于随机接入消息获得终端能力信息。响应于接收到该指示信息，确定已基于随机接入消息发送终端能力信息。
在一个实施例中，基站在接收到指示终端能力信息的随机接入消息后，向终端发送指示信息。
在一个实施例中，响应于已基于随机接入消息发送终端能力信息，向基站发送第一终端能力上报消息；其中，第一终端能力上报消息不携带最小终端能力集合指示的第一终端能力参数或者携带最小终端能力集合指示的第一终端能力参数之外的第二终端能力参数。

这里，不同类型的终端可以支持不同的终端能力。这里，终端能力可以是终端接入层能力。在一个实施例中，终端支持的终端能力可以通过天线数量和不同的通信带宽等参数进行指示。例如，终端为指示支持1个天线和20Mhz通信带宽的Redcap终端。这里，需要说明的是，终端支持的的终端能力可以通过多次上报时机上报。每次可以上报全部终端能力中的部分终端能力。例如，终端支持的全部终端能力为支持2个天线和40Mhz通信带宽，则终端在第一次上报终端能力时，可以先上报支持1个天线和20Mhz通信带宽的终端能力，在第二次上报终端能力时，再上报支持2个天线和40Mhz通信带宽的终端能力。对应地，基站也可以通过多次接收终端发送的终端能力信息。
在一个实施例中，响应于基站接收到终端能力信息，根据该终端能力信息确定终端是否能够驻留在该基站对应的小区内。例如，可以是不允许只支持单天线的终端能力的终端接入网络。在一个实施例中，基站向终端发送指示信息，该指示信息用于指示终端是否可以驻留在小区上。这里，该指示信息可以是根据终端的天线数量和/或通信带宽确定的。终端在接收到该指示信息后就可以确定是否能够驻留在小区上。
