Embodiment Construction
[0051] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0052] Refer to attached figure 1, the application scenario of the present invention is a multi-cell scenario. The coverage of the macro base station A is called a macro cell, and there are five micro base stations within the scope of the macro cell, which are respectively micro base stations B, C, D, E, and F. The coverage area of the micro base station is called microcells. The user is in sector a, and sector a covers three micro base stations, namely micro base stations B, C, and D.
[0053] Refer to attached figure 2 , specifically describe the specific steps for realizing the present invention.
[0054] Step 1, determine the sector where the user is located.
[0055] According to the sector division method, the macro base station A evenly divides the coverage area of the UHF signal into multiple sectors.
[0056] The sector division method mean...

The invention discloses an ultra high frequency signal assisting-based millimeter wave microcell selection method, which comprises the following steps: 1, a sector where a user is positioned is determined; 2, an ultra high frequency indicator signal is transmitted; 3, a millimeter wave positioning detection signal is transmitted; 4, a micro base station processes information; 5, whether a millimeter wave microcell capable of accepting a new user exists or not is judged; 6, the micro base station feeds back information; 7, whether a millimeter wave microcell meeting a legal communication condition exists or not is judged; 8, the position of the user is estimated; 9, the micro base station scans the user; 10, whether the millimeter wave microcell meeting the legal communication condition exists or not is judged; 11, the micro base station feeds back information; 12, a candidate cell list is established; 12, the micro base station is selected for communication; 14, a macro base station directly communicates with the user. According to the method, searching time can be reduced, searching efficiency can be improved, and the aim of rapidly selecting the millimeter wave microcell can be fulfilled.
Description
technical field [0001] The invention belongs to the technical field of communication, and further relates to a millimeter-wave microcell selection method assisted by an ultra-high frequency UHF (Ultra High Frequency) signal in the technical field of wireless communication. The present invention is applicable to heterogeneous network, ultra-high frequency UHF signal base station, selects the millimeter-wave signal transmission base station according to the information obtained from user beam search, and sends ultra-high frequency UHF signal to notify the user to access the millimeter-wave signal transmission base station to establish communication . Background technique [0002] In recent years, wireless communication networks mainly use the 400MHz-3GHz frequency band to realize communication between user base stations and users. This frequency band can balance the coverage area capability and the ability to handle a large number of users, which is conducive to the wide appli...
