    • The invention discloses an adaptive phase shift method in a multi-carrier system, comprising: generating a group of one or more new phase values for corresponding one or more phase shift carriers, PSCs, based on quantization phase values; calculating and comparing a backward maximum power in an evaluation path with the group of one or more new phase values in one timeslot and a forward maximum power in a working path with current phase values in the timeslot; and adjusting phase of the PSCs based on the group of one or more new phase values if the calculated backward maximum power is less than the calculated forward maximum power. An adaptive phase shift apparatus is also disclosed. With the invention, complexity of the implementation is reduced and a small DPS block resource, low Hardware cost, low power consumption is also achieved.

    • The present disclosure provides a method in a base station of a radio network for antenna calibration of a first transceiver of the base station with respect to a second transceiver. The method comprises at least one of a first group and a second group of steps. The first group of steps comprises collecting a first group of amplitude and phase differences between a first calibration signal and each of a first and a fourth reception signals and between a second calibration signal and each of a second and a third reception signals. The first group of steps further comprises estimating, based on the first group of amplitude and phase differences, a signal response characteristic difference between a calibration reception chain of the first transceiver and a calibration reception chain of the second transceiver for reference antenna reception calibration of the first transceiver with respect to the second transceiver.
