相关技术中，5G的发展已成为必然趋势，而UE会产生更高的传输速率需求。然而，当前UE所选的基站所支持的工作频率范围很可能满足不了该UE所需的传输速率，因此亟需一种更合理的通信方法，以使UE能够选择最适合自身传输速率需求的基站。
本公开实施例中，UE通过获取多个基站的系统信息，该系统信息包括第一带宽信息，可以确定每个基站能够为该UE提供的工作频率范围，使得UE可以选择一个工作频率范围与自身工作频率范围交集较大的目标基站，使得目标基站既符合该UE的工作频率范围，而且可以为该UE提供较大的传输带宽，从而可以尽可能满足UE的传输速率需求。

本公开实施例中，任一基站可以根据UE需求将系统信息提供给该UE，系统信息包括第一带宽信息，使得UE可以确定每个基站能够提供的工作频率范围，因此UE可以选择一个工作频率范围与自身工作频率范围交集较大的基站，该基站既符合该UE的工作频率范围，也可以为该UE提供较大的传输带宽，从而可以尽可能满足UE的传输速率需求。
在本公开实施例中，系统信息可能是基站周期性广播的，也可能是UE主动请求基站发送的。因此，对于第一种广播系统信息的方式，采用图4实施例进行说明；对于第二种请求系统信息的方式，采用图6实施例进行说明。但对于UE来说，所获取的多个系统信息既可以来源于基站广播的系统信息、也可 以来源于主动请求的系统信息。
图4是根据一示例性实施例示出的一种通信方法的流程图，如图4所示，该实施例应用于基站和用户设备UE的交互过程，具体包括以下步骤：
在步骤401中，基站广播系统信息，系统信息包括基站的第一带宽信息，第一带宽信息用于指示基站在载波聚合时支持的工作频率范围。
载波聚合是指该基站调度并使用其他基站的工作带宽，以增加该基站与UE通信时的传输带宽。由于运行商分配的频段和工作带宽不同，载波聚合的可能方式为：频段内载波聚合(包括频段内连续载波聚合和频段内非连续载波聚合)、频段间载波聚合。本公开实施例对基站的载波聚合的方式、带宽和数量均不做限定。
例如，图5是根据一示例性实施例示出的一种载波聚合示意图。如图5所示，该基站的工作带宽为20M，处于F频段内的1885M～1905M，且该基站支持与F频段内的1905M～1915M和D频段内的2570M～2590M聚合，使得该基站所能提供的的传输带宽由20M增至50M。因此该基站的第一带宽信息包括1885M～1915M和2570M～2590M。当然，为了在5G网络中为UE提供更高的传输速率，通过聚合125个80M的工作带宽，基站的传输带宽可以增至1G。需要说明的是，本公开实施例对第一带宽信息指示工作频率范围的形式不做限定。例如，第一带宽信息可以包括工作频率范围的数值，从而直接指示该基站在载波聚合时支持的工作频率范围。又例如，第一带宽信息可以包括工作频率范围对应的至少一个频率范围标号，该频率范围标号用于唯一标识一段频率范围。
系统信息是指UE接入基站所需的基本信息，包括工作带宽、系统帧号和天线数目等信息。本公开实施例中，为使UE判断该基站所支持的工作频率范围是否能满足自身需求，系统信息包括第一带宽信息。
在该步骤中，任一基站均可以周期性广播系统信息。本公开实施例对该系统信息的广播周期和对应的时频资源不做限定。一般地，广播周期为10毫秒，且该系统信息对应的时域资源为子帧0、对应的频域资源为该基站的中心频段(1.08M)。
在步骤402中，UE获取多个基站的系统信息。
本公开实施例中，UE可以在已配置的通信频点上搜索基站的系统信息。由于基站的通信覆盖范围往往会有重叠，因此当UE处于多个基站的通信覆盖 范围内时，可以通过搜索获取到多个基站的系统信息。其中，多个是指两个或两个以上。当然，该步骤UE所获取的系统信息也可以包括通过请求方式获取到的系统信息，该请求方式具体在图6实施例进行说明。本公开实施例对获取的时机不做限定。例如，UE可以在开机启动时进行获取，或者，UE在重选基站时进行获取。
需要说明的是，UE在搜索基站时，通常先搜索基站的同步信息，同步信息用于UE与基站实现时域同步，且位于基站的中心频段内。因此一旦在某一通信频点上搜索到基站的同步信息，则可以继续在该频点所处的中心频段内搜索系统信息。
在步骤403中，UE基于多个第一带宽信息与UE已配置的第二带宽信息，从多个基站中选择目标基站，第二带宽信息用于指示UE在载波聚合时支持的工作频率范围，目标基站是指在载波聚合时支持的工作频率范围与UE在载波聚合时支持的工作频率范围的交集较大的基站。
本步骤中，UE基于已配置的第二带宽信息，对获取到的多个第一带宽信息进行分析，确定任一基站在载波聚合时支持的工作频率范围与该UE在载波聚合时支持的工作频率范围的交集，并从中选择交集较大的基站作为目标基站，以尽可能满足该UE的传输速率需求。本公开实施例对UE载波聚合的方式、数量和带宽均不做限定。例如，该UE支持F频段内的1885M～1905M、1905M～1915M和D频段内的2570M～2590M聚合，因此该UE的第二带宽信息包括1885M～1915M和2570M～2590M。需要说明的是，第二带宽信息与第一带宽信息同理，本公开实施例对第二带宽信息指示工作频率范围的形式不做限定。
本公开实施例中，对选择目标基站的具体过程不做限定。例如，选择过程为：对于多个第一带宽信息中的每个第一带宽信息，分析第一带宽信息所指示的工作频率范围与第二带宽信息所指示的工作频率范围之间的交集；确定交集的频率范围；将对应交集的频率范围最大的基站确定为目标基站。
根据举例的选择过程，如果第一带宽信息和第二带宽信息分别包括工作频率范围的数值，例如：UE的第二带宽信息包括B1(3600M～4600M)，UE获取到两个第一带宽信息分别包括B2(3600M～4000M)和B3(3600M～4600M)，则UE可以确定B1与B2的交集为3600M～4000M，B1与B3的交集为3600M～4600M，并计算得到B1与B2交集的频率范围数值为400M，B1与B3 交集的频率范围数值为1000M，通过比较两个交集的频率范围数值，确定B1与B3交集的频率范围数值最大，则将B3对应的基站确定为目标基站。
另外，如果第一带宽信息和第二带宽信息分别包括工作频率范围对应的频率范围标号，例如，UE的第二带宽信息data1包括C1(3600M～3680M)、C2(3680M～3760M)、C3(3760M～3840M)，UE获取到第一带宽信息data2包括C1(3600M～4000M)和C2(3680M～3760M)，第一带宽信息data3包括C1(3600M～4600M)、C2(3680M～3760M)、C3(3760M～3840M)、C4(3840M～3920M)，则UE可以确定data1与data2所指示的工作频率范围的交集为C1和C2，data1与data3所指示的工作频率范围的交集为C1、C2和C3，因此可以将data3对应的基站确定为目标基站。
事实上，该步骤的选择过程也可以综合考虑其他因素，不限于该基站的信号质量、或者接入优先级。例如，该UE的第二带宽信息包括B1，且获取到三个第一带宽信息，分别包括B4、B5和B6。其中，B1为3600M～4600M，B4为3600M到4000M，B5为3600M～4600M，B6为3600M～4600M。此时，B1与B5或B6的交集较大且相同，因此UE可以衡量B5和B6对应基站的信号质量，并将信号质量最好的基站确定为目标基站。
在步骤404中，UE向目标基站发送连接请求，连接请求用于指示UE与目标基站进行通信。
基于上述步骤403，UE可以选择一个目标基站进行驻留。当触发通信过程时，该UE可以生成连接请求，并发送至目标基站。
在步骤405中，目标基站接收用户设备UE所发送的连接请求。
当目标基站接收到该UE所发送的连接请求时，可以与该UE之间建立连接，并与UE进行后续的通信过程。
需要说明的是，基站(或UE)在载波聚合时支持的工作频率范围是基站(或UE)载波聚合能力的体现，并不表示该基站(或UE)在通信时一定会采用该工作频率范围内的频率进行通信，本公开实施例对该UE与目标基站通信时采用的传输带宽不做限定。例如，根据当前基站(或UE)的调度需求决定传输带宽，如果该UE当前没有较高的传输速率需求，则目标基站可以采用自身的工作带宽与UE进行通信。又例如，根据运营商所分配的传输资源决定传输带宽。
相关技术中，5G的发展已成为必然趋势，而UE会产生更高的传输速率需 求。然而，当前UE所选的基站所支持的工作频率范围很可能满足不了该UE所需的传输速率，因此亟需一种更合理的通信方法，以使UE能够选择最适合自身传输速率需求的基站。
本公开实施例中，UE通过获取多个基站的系统信息，该系统信息包括第一带宽信息，可以确定每个基站能够为该UE提供的工作频率范围，使得UE可以选择一个工作频率范围与自身工作频率范围交集较大的目标基站，使得目标基站既符合该UE的工作频率范围，而且可以为该UE提供较大的传输带宽，从而可以尽可能满足UE的传输速率需求。
图6是根据一示例性实施例示出的一种通信方法的流程图，如图6所示，该实施例应用于基站和用户设备UE的交互过程，具体包括以下步骤：
在步骤601中，如果UE获取到任一基站的同步信息，但在预设时长内没有获取到基站的系统信息，则向基站发送系统信息请求，系统信息请求用于指示基站将系统信息发送至UE。
该实施例中，该基站不同于周期性广播系统信息的基站，而是根据UE的需求为UE提供系统信息，从而可以节省广播系统信息所占用的时频资源。因此，对于UE来说，如果该UE获取到基站的同步信息，说明UE处于该基站的通信覆盖范围内，该基站有可能支持与该UE进行通信。进一步地，UE可以进一步在该基站的中心频段内搜索系统信息，如果在预设时长内没有获取到系统信息，UE可以生成系统信息请求，并将系统信息请求调制到该中心频段内的频率上，从而将系统信息请求发送至该基站，该系统信息请求该UE的UE标识，UE标识不限于sim(Subscriber Identity Module，客户识别模块)卡标识。
其中，预设时长已配置在UE中，本公开实施例对预设时长不做具体限定。例如，预设时长为一帧(10毫秒)。另外，本公开实施例对UE获取同步信息的时机不做限定。例如，UE在开机启动时进行获取，或者，UE在重选基站时进行获取。
在步骤602中，基站接收UE所发送的系统信息请求。
该步骤中，基站可以在自身的中心频段内监听到UE所发送的系统信息请求，并进行接收。
在步骤603中，基站基于系统信息请求，将系统信息发送至UE，系统信息包括基站的第一带宽信息，第一带宽信息用于指示基站在载波聚合时支持的 工作频率范围。
通过接收到的系统信息请求，基站可以根据系统信息请求中携带的UE标识，调制到该基站中心频段内的频率上，并将系统信息发送至具有该UE标识的UE。
在步骤604中，UE获取多个基站的系统信息。
该步骤与步骤402同理。
而且，无论基站采用广播系统信息的方式，还是根据UE需求发送的系统信息，UE均可以在该基站的中心频段内搜索到该系统信息。
在步骤605中，UE基于多个第一带宽信息与UE已配置的第二带宽信息，从多个基站中选择目标基站，第二带宽信息用于指示UE在载波聚合时支持的工作频率范围，目标基站是指在载波聚合时支持的工作频率范围与UE在载波聚合时支持的工作频率范围的交集较大的基站。
该步骤与步骤403同理，不再赘述。
在步骤606中，UE向目标基站发送连接请求，连接请求用于指示UE与目标基站进行通信。
该步骤与步骤404同理，不再赘述。
在步骤607中，目标基站接收UE所发送的连接请求。
该步骤与步骤405同理，不再赘述。
相关技术中，5G的发展已成为必然趋势，而UE会产生更高的传输速率需求。然而，当前UE所选的基站所支持的工作频率范围很可能满足不了该UE所需的传输速率，因此亟需一种更合理的通信方法，以使UE能够选择最适合自身传输速率需求的基站。
本公开实施例中，UE通过获取多个基站的系统信息，该系统信息包括第一带宽信息，可以确定每个基站能够为该UE提供的工作频率范围，使得UE可以选择一个工作频率范围与自身工作频率范围交集较大的目标基站，使得目标基站既符合该UE的工作频率范围，而且可以为该UE提供较大的传输带宽，从而可以尽可能满足UE的传输速率需求。
