摘要： A Doppler frequency estimation system includes a basis projector, a polynomial generator and an extreme value determinator. The basis projector receives and projects multiple channel sampling signals to a set of orthogonal bases to thereby generate multiple channel correlation vectors. The polynomial generator is connected to the basis projector in order to produce a target polynomial based on the channel correlation vectors, an estimated channel-envelope-to-noise-plus-interference power-ratio and a channel-envelope power. The extreme value determinator is connected to the polynomial generator in order to determine an extreme value of the polynomial and output a frequency corresponding to the extreme value as an estimated Doppler frequency.

摘要： A method for providing a buffer status report in a mobile communication network is implemented between a base station and a user equipment. When data arrives to buffers of the user equipment and the priority of a logical channel for the data is higher than those of other logical channels for existing data in the buffers, a short buffer status report associated with the buffer of a logical channel group corresponding to the arrival data is triggered. The user equipment is based on obtained resources allocated by the base station to fill all data of the buffer of the logical channel group in a Protocol Data Unit. If all data of the buffer of the logical channel group corresponding to the arrival data can be completely filled in the Protocol Data Unit, the short buffer status report is canceled. Otherwise, the user equipment transmits the short buffer status report.

摘要： A method for mitigating interference is provided. First, a received signal having a training sequence is received from a transmitter. Then, a Signal-to-Interference-plus-Noise Ratio (SINR) of the training sequence in the received signal is calculated, and whether a co-channel interference signal exists in the received signal is determined according to the SINR. The signal power corresponding to each time index in the received signal is calculated to detect a beginning time point and an ending time point of the co-channel interference signal. Finally, when the co-channel interference signal in the received signal is detected, the time when an interference cancellation filter is turned on is determined by the beginning time point and the ending time point.
