The present disclosure provides a vector quantization based secret key generation device and method. The vector quantization based secret key generation device includes: a channel estimator for estimating a channel based on received signals to generate an estimated channel vector; a channel decorrelator for decorrelating entries of the estimated channel vector to generate a decorrelated estimated channel vector; a plurality of clustered vector quantizers (CVQs) each for quantizing the decorrelated estimated channel vector into a secret key or a secret key index; and a selector for selecting an optimal quantizer output from the plurality of CVQs and determining whether to discard the decorrelated estimated channel vector to reduce key disagreement probability (KDP). Therefore, the present disclosure provides a secret key generation technique that is capable of increasing key entropy and reducing KDP.

A communication system, a base station, a user equipment (UE), and a timing synchronization method for the base station thereof are provided. The communication system includes a first base station, a second base station and the user equipment. The UE is located within coverage of the first base station and the second base station. The first base station and the second base station respectively measure signal stability of the user equipment so that the second base station selects the user equipment based on the measurements for the stability of the signals. The first base station computes a first timing error for transmitting or receiving message between the first base station and the user equipment then transmits the first timing error to the second base station. The second base station adjusts a timing difference between the first base station and the second base station through the first timing error.
