    摘要： A semi-single frequency network (SFN) concept is presented. According to the SFN concept, the same data signal is transmitted from multiple base stations to a mobile terminal simultaneously on the same frequency band. Accordingly, the transmitted signals are combined in the radio channel and the mobile terminal experiences the transmitted signals as one signal propagated through a multipath channel. Additionally, each base station transmits a base station specific pilot signal. The mobile terminal carries out a channel estimation procedure for each received pilot signal and combines the channel estimates to obtain information how to equalize the received data signal. Then, the mobile terminal calculates equalization weights from the combined channel estimates and equalizes the received data signal.

    摘要： The specification and drawings present a new method, system, apparatus and software product for using DL sub-frames with a unique pilot structure for TDD communications between a network element and a user equipment. In order to have equally good estimation for, e.g., channel, SIR and/or CQI estimation in the edges of a TDD sub-frame, the pilot structure should take into account UL/DL frame boundaries. In other words, a DL TDD sub-frame (e.g., 0.5 ms in duration) or sub-frames, adjacent in time domain to an UL TDD sub-frame can have higher total pilot energy than non-adjacent downlink TDD sub-frames by a pre-selected value or values.
