Description

一种分级波束接入方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种分级波束接入方法及装置。
背景技术
在高频通信时，由于采用了更高的载波频率进行传输，那么平均的路损会比传统的长期演进高级系统(Long term evolution advanced system，简称为LTE-Advanced)大很多，例如我们采用28GHz的载频进行传输，利用公式：
Figure PCTCN2015092864-appb-000001
计算得出高频路损值与LTE路损值的平均比例信息为：
Figure PCTCN2015092864-appb-000002
在高频通信中为了保证覆盖，即接收侧满足最小信号与干扰加噪声比(Signal to Interence plus Noise Ratio，简称为SINR)要求，需要提高发送和接收机增益。
Figure PCTCN2015092864-appb-000003
其中，R为小区覆盖的半径，λ为对应载波的波长，Gt为发送天线增益，Gr为接收天线增益。
LTE通信需求最高要求达到覆盖100km的区域，如果按照最高覆盖，仅仅考虑平均路损(空旷区域)，那么高频通信最高可以考虑覆盖达到1km的区域。如果考虑实际高频载波的高空气吸收度(氧气吸收，雨衰落，雾衰落)以及对于阴影衰落敏感等特点，实际可以支持的覆盖要小于1km。
如果高频通信支持最大1km覆盖，与LTE系统相比，相同的覆盖区域可以获得的SINR比不同，前者比后者存在至少20dB的信噪比下降，为了保证高频通信与LTE系统覆盖范围内具有近似的SINR，需要保证高频通信的天线增益。这时值得我们庆幸的是，由于高频通信具有更短的波长，从而可以保证单位面积上容纳更多的天线元素，更多的天线元素可以提供更高的天线增益，从而保证高频通信的覆盖性能。
更多的天线元素意味着我们可以采用波束赋型的方法来保证高频通信的覆盖。由LTE先前的设计思想可知，要想得到好的波束赋型效果需要准确的获得信道的状态信息，从而从信 道的状态信息中获得波束赋型的权值。而获得较好的波束赋型权值，对于发送端第一节点来说，接收端第二节点需要反馈下行的信道状态信息或者权值，对于接收端来说，发送端第一节点需要反馈上行的信道状态信息或者权值，从而保证第一节点可以采用最优的波束发送下行业务，第二节点也可以采用的最优的波束发送上行业务。这时就会存在一个“鸡生蛋，蛋生鸡”问题，第一节点在获得权值前，无法利用最优的波束覆盖到接收端，从而接收端无法测量第一节点发送的参考信号进行测量，或者即使第一节点覆盖到第二节点，但是第二节点无法达到第一节点的同样的覆盖，反馈的内容第一节点无法获知，从而也不能进行波束权值的选择和正常通信。解决这个问题的最优方法就是加入一种发现过程，通过这个发现过程来使得第一节点和第二节点得以发现对方，从而利用最优的权值进行通信。
简单的说发现过程其实就是训练的过程，发送端通过预先发送多个波束序列信号(发现信号)，来使得接收端可以检测到这种序列，获得波束序号并反馈的过程，在发送端和接收端发现彼此存在后即可以进行初步的进行通信。
第二节点在进行同步时，需要检测同步信号用于时间同步和频率同步，同时第二节点需要检测发现信号来获得最优波束索引信息。另外，第二节点可以通过检测同步信号同时获得时间同步和频率同步以及最优波束索引信息。
针对相关技术中，第一节点或者第二节点无法高效的获取最优波束的问题，还未提出有效的解决方案。
