Embodiment Construction
[0031] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0032] A millimeter-wave cellular system cell handover judgment method in a high-low frequency hybrid network. This method uses a variety of filters to filter the measured handover parameters, changes the trigger time of handover in the decision algorithm, and adds handover judgment based on location awareness. , including the following steps:
[0033] S1. Channel information acquisition: In the process of cell switching, the millimeter wave base station first tracks the channel information of the mobile user, studies the signal-to-noise ratio of the user signal received by each base station, and uses the pilot signal from the user received by the millimeter wave base station , to calculate the SINR, so as to obtain the best SINR transmit beam and receive beam, and use this SINR value to represent the measured channel....
