    摘要： A method of searching for the presence of a useful signal of predefined spectral width ΔB in a multiplexing band having a spectral width greater than ΔB, includes calculating a frequency signal representative of a power spectral density in the multiplexing band, calculating a non-useful signal by filtering the frequency signal by means of a filter capable of suppressing all or part of signals having a spectral width equal to or smaller than ΔB, calculating a power ratio signal representative of the ratio of the frequency signal to the non-useful signal, and comparing the power ratio signal with a predefined threshold value. The method may be employed using a computer program product, a receiver unit, and/or a station of a digital telecommunications system comprising such a receiver unit.

    摘要： Embodiments of the present disclosure disclose a signal transmission apparatus and method, and a wireless access node, and relate to the field of communications technologies, so as to resolve a problem that a spectrum cannot be fully used. The method of the present disclosure includes: obtaining, by a wireless access node, configuration information for use to transmit a signal of a second carrier in coverage space of a first carrier, a spectrum occupied by the first carrier and a spectrum occupied by the second carrier overlap, and a subcarrier of the first carrier and a subcarrier of the second carrier are orthogonal; and transmitting, by the wireless access node, the signal of the second carrier according to the configuration information. The present disclosure is applicable to a scenario in which a signal of a carrier is transmitted in coverage space of another carrier.

    摘要： Embodiments provide apparatuses, methods, and computer programs for a receiver and a transmitter of a wireless system. An apparatus (10) for a receiver (100) of a wireless communication system comprises means for receiving (12) radio signals, which are organized in repetitive radio frames, a radio frame being subdivided in sub-frames. The apparatus (10) further comprises means for extracting (14) a first payload data packet from the received radio signals using a single sub-frame of the received radio signals and for extracting a second payload data packet using two or more sub-frames of two or more radio frames. An apparatus (20) for a transmitter (200) comprises means for obtaining (22) information on a subset of radio resources for scheduled and/or non-scheduled transmission. The apparatus (20) further comprises means for transmitting (24) radio signals, which are organized in repetitive radio frames, a radio frame being subdivided in sub-frames, the means for transmitting (24) is operable to transmit a first payload data packet using a single sub-frame of the radio signal and for transmitting a second payload data packet using two or more sub-frames.

    摘要： A communications node operable to communicate with another communications node over a communications channel having a plurality of frequency resources, the communications node includes data defining a division of the communications channel into a plurality of contiguous sub-bands each having N frequency resources, wherein each frequency resource in a sub-band has a corresponding frequency resource in each of the other sub-bands, data defining an initial allocation of the frequency resources, a resource determination module operable to apply a frequency shift to the initially allocated frequency resources in accordance with a frequency hopping sequence to determine frequency resources to use for communicating information with the other communications node, wherein the frequency shift applied moves the initially allocated frequency resources to corresponding frequency resources in another sub-band, a transceiver for communicating information with the other communications node using the determined frequency resource.
