Abstract: A communication device for detecting an object includes a power module, an antenna array, a first sensor pad, a second sensor pad, and a control unit. The antenna array is excited by the power module, and is configured to provide a first beam group and a second beam group. The first sensor pad is disposed adjacent to the first side of the antenna array. A first capacitance is formed between the first sensor pad and the object. The second sensor pad is disposed adjacent to the second side of the antenna array. A second capacitance is formed between the second sensor pad and the object. The control unit controls the power module according to the first capacitance and the second capacitance, so as to selectively apply at least one power backoff operation to the first beam group and/or the second beam group.

Abstract: A beam management method of an electronic device includes transmitting a detecting signal, receiving a reflecting signal of the detecting signal, determining blocked antennas of an antenna array of the electronic device according to the reflecting signal, and exciting only unblocked antennas of the antenna array. This will improve the radiation efficiency of the antenna array.

Abstract: An idle time prediction method for a system includes obtaining n idle durations corresponding to n time points, determining if the n idle durations are of a normal distribution, generating a probability according to m idle states corresponding to m idle durations of the n idle durations if the n idle durations are not normally distributed, selecting a predicted idle state according to the probability, and controlling the system to enter the predicted idle state, where n and m are integers larger than one, and m≤n.
