Abstract: The present disclosure provides several methods, user equipment (UEs) and base stations for transmitting uplink signals. After receiving uplink synchronization command information, the UE may transmit an uplink signal on at least one idle unlicensed cell. Besides, the UE may try to transmit the uplink signal on multiple uplink signal resources within an uplink signal transmission window. By using the present disclosure, transmission probability of uplink signals may be improved, and time delay of uplink synchronization may be shortened.

Abstract: An apparatus and a method for feeding back data receiving status, applied to a system, are provided. The method includes sequencing, by a User Equipment (UE), downlink subframes for transmitting data with respect to each Component Carrier (CC), generating receiving status feedback information for the first X downlink subframes with respect to each CC according to the result of the sequencing, where X≤M, wherein M is the number of downlink subframes on each CC, and transmitting the receiving status feedback information generated with respect to each CC to a base station. Accordingly, the UE will not misinterpret the receiving status for the downlink subframes due to inconsistencies with the base station between transmitting and receiving feedback. This affects the Hybrid Automatic Repeat Request (HARQ) transmission, saves the uplink overheads occupied by the receiving status feedback information, and increases the uplink coverage area.

Abstract: A filtering-based signal transmission method is provided. The method includes a transmitter performing carrier modulation on each signal from at least one sub-band, and adding a cyclic prefix and a cyclic postfix thereto, respectively, performing time-domain filtering on the signal, added with the cyclic prefix and the cyclic postfix, from the respective sub-band, and transmitting the filtered signal from the at least one sub-band. The present disclosure further provides a filtering-based signal receiving method. The filtering-based signal receiving method includes performing, by a receiver, time-domain matched filtering, corresponding to at least one sub-band, on each received signal, removing, by the receiver, a cyclic prefix and a cyclic postfix from the filtered signal from the at least one sub-band, and performing carrier demodulation, respectively, and detecting and estimating, by the receiver, the demodulated signal from the at least one sub-band.
