    摘要: A wireless communication system and a method for detecting downlink receiving power in the system are disclosed. N cells in the system respectively transmit data to at least one receiving terminal via N resource blocks using the same time-frequency resources; multiple channel state information reference signals (CSI-RSs) of a corresponding cell are set in each resource block, and orthogonality is maintained among the CSI-RSs of all the cells, wherein N is an integer greater than 1. Said method includes: an additional demodulation reference signal (DM-RS) used for indicating a receiving power is set in a puncture position in the resource block of the first cell which corresponds to a CSI-RS set in a resource block of another cell; and the receiving power of said first cell is detected according to said additional DM-RS. By using said method, the receiving power of a single cell in N cells can be detected, and the system overhead is not increased.

    摘要: A method for reducing interferences between base stations in a communication system having a plurality of base stations. This method comprises the steps of: causing a user station to receive both a signal transmitted by a local-cell base station and a signal transmitted by an adjacent-cell base station, thereby measuring the SNR of the interfered link and the SNR of the leak link of the adjacent-cell base station; calculating a weighting factor of a leak power based on the measured SNR of the interfered link and the measured SNR of the leak link of the adjacent-cell base station; and determining, based on the calculated weighting factor, whether or not the leak power has to be suppressed and to what degree such suppression has to be performed.

    摘要: A display is provided that has upper and lower polarizers, a color filter layer, a liquid crystal layer, and a thin-film transistor layer. The color filter layer and thin-film transistor layer may be formed from materials such as glass that are subject to stress-induced birefringence. To reduce light leakage that reduces display performance, one or more internal layers may be incorporated into the display to help ensure that linearly polarized backlight that passes through the display is not undesirably converted into elliptically polarized light. The internal layers may include a thin-film polarizer layer that forms a coating on the color filter layer, a thin-film polarizer layer that forms a coating on the thin-film-transistor layer, a retarder layer that is formed as a coating on the color filter layer, and a retarder layer that is formed as a coating on the thin-film-transistor layer.
