Description

一种确定、发送小区参数集合的方法、设备及系统 技术领域
本发明涉及通信领域，尤其涉及一种确定、发送小区参数集合的方法、设备及系统。
背景技术
随着移动业务性能的需求越来越高,移动通信技术已经发展到了第五代移动通信技术(英文全称：5th-Generation，5G)。5G具备更高的业务性能，5G新的无线接入技术(英文全称：New Radio Access Technologies，RAT)中定义了新的空口接入技术，可以支持更快的用户体验速率，更高的连接数密及流量密度度，毫秒级的端到端时延，更快的峰值速率。同时，5G还大幅提高网络部署和运营的效率。当前，已经确定5G NR中支持多种子载波间隔、符号长度、子帧长度等参数。
在通信过程中，终端通常依据小区的参数集合与基站间进行信号传输。例如，长期演进(英文全称：Long Term Evolution，LTE)系统的小区参数集合为子载波间隔15kHz、子帧长度1ms、一个子帧包括14个或12个符号。LTE系统中小区参数集合固定，且基站与终端共知，终端可以直接采用固定的小区参数集合与基站间进行信号传输。
但是，由于5G NR中技术中，小区支持多种参数集合，在接入网络之前，终端并不知道某个小区使用哪种参数集合，因此，终端需要先识别小区的参数集合，才能与基站进行信号传输。所以，在5G NR中终端如何识别小区的参数集合成为亟待解决的问题。
发明内容
本发明实施例提供一种确定、发送小区参数集合的方法、设备及系统，实现在支持多种小区参数集合的5G NR中终端可识别小区的参数集合。
为达到上述目的，本发明的实施例采用如下技术方案：

本申请提供的确定小区参数集合的方法，通过识别信号的特征信息携带小区的参数集合，识别信号不同的特征信息即可准确区分小区不同的参数集合，当终端获取到识别信号时，即可根据识别信号的特征信息准确识别出小区的参数集合，实现在支持多种小区参数集合的5G NR中终端可识别小区的参数集合。
在一种可能的实现方式中，根据识别信号的特征信息，确定小区的参数集合，具体可以实现为：根据识别信号的特征信息，从N个参数集合中确定小区的参数集合；N大于或等于2。其中，N个参数集合为小区所属的通信系统的通信标准中定义的小区支持的参数集合。这样一来，终端可以根据识别信号的特征信息，在小区支持的多个参数集合中准确识别小区的参数集合，提高了识别的效率。
在另一种可能的实现方式中，根据识别信号的特征信息，确定小区的参数集合，包括：根据识别信号的特征信息和映射关系，确定小区的参数集合；映射关系包括分别特征信息与至少一个参数集合的对应关系。通过映射关系表示信号的特征信息与参数集合的对应关系，终端在获取到识别信号的特征信息时，可以直接查找确定小区的参数集合，实现简单快速。
其中，在映射关系中，可以是一组特征信息唯一对应一组参数集合。或者，在映射关系中，也可以是特征信息中的一个信息对应多个参数集合，这组特征信息中每个信息对应的参数集合的交集为 唯一的参数集合。或者，在映射关系中，也可以是参数集合中的一个参数对应多组特征信息，这个参数集合中每个参数对应的特征信息的交集为唯一的特征信息。本申请对于映射关系中的具体对应内容不进行限定。
在另一种可能的实现方式中，提供一种获取小区的识别信号特征信息的实现方案，具体可以包括：按照参考参数集合进行匹配，获取小区的识别信号，解析识别信号的获取识别信号的特征信息。也就是说，不论小区的参数集合的内容是什么，识别信号均按照参考参数集合发送，终端在获取识别信号时，按照参考参数集合进行匹配即可，使得识别信号的接收实现简单，降低了终端的检测复杂度。
结合第一方面或上述任一可能的实现方式，在另一种可能的实现方式中，提供另一种获取小区的识别信号特征信息的实现方案，具体可以包括：依次按照预设M个的参考参数集合进行匹配，直至获取小区的识别信号，解析识别信号的获取识别信号的特征信息；M大于或等于2。识别信号按照小区的参数集合发送，终端在获取识别信号时，按照可能的参数集合盲检进行匹配。因此，识别信号的设计简单。
本申请的第二方面，提供一种发送小区参数集合的方法，应用于基站。该方法具体包括：根据小区的参数集合，确定识别信号的特征信息；以确定的识别信号的特征信息，向终端发送识别信号。小区的参数集合包括下述参数中的至少一项：子载波间隔、子帧长度、符号长度、时隙长度、CP长度、子帧中的符号数、时隙中的符号数、子帧类型、时隙类型、CP类型、双工模式、是否授权频谱、是否独立载波、是否多波束、波束的数量、业务需求。
本申请提供的发送小区参数集合的方法，通过识别信号的特征信息携带小区的参数集合，识别信号不同的特征信息即可准确区分小区不同的参数集合，发送识别信号即完成小区参数集合的发送。当终端获取到识别信号时，即可根据识别信号的特征信息准确识别 出小区的参数集合，实现在支持多种小区参数集合的5G NR中终端可识别小区的参数集合。
在一种可能的实现方式中，根据小区的参数集合，确定识别信号的特征信息，包括：根据小区的参数集合和映射关系，确定识别信号的特征信息；映射关系包括包括参数集合与至少一个特征信息的对应关系。通过映射关系表示信号的特征信息与参数集合的对应关系，基站在发送识别信号时，可以直接查找映射关系确定识别信号的特征信息，实现简单快速。
其中，第二方面中的映射关系，与第一方面中的映射关系相同，此处不再进行赘述。
