摘要： A technique for transmitting data on carriers each using a non-sinusoidal waveform is described. As to a method aspect of the technique, a fundamental frequency (118) is assigned to each of the carriers using the non-sinusoidal waveform. Baseband frequencies corresponding to a set of harmonic components of the non-sinusoidal waveform at each of the assigned fundamental frequencies (118) are disjoint. An energy of each of the harmonic components in the set is greater than a predefined threshold value. Modulation symbols (116) representative of the data are transmitted on at least one or all of the carriers.

摘要： A wireless communication node (130) and method therein for generating beamformed signals by means of backscattering in a wireless communication network are disclosed. The wireless communication node (130) receives a radio frequency signal at a plurality A of antennas (310). Each antenna is coupled to one of a number of impedance matrices (330) by one of a plurality A of switches (320). The wireless communication node (130) generates a first baseband signal based on data symbols to be transmitted in a baseband signal generator (340). The states of each switch are controlled based on its specific switch control signal such that each antenna impedance is selected among a number M of impedances, and thereby the received RF signal at each antenna is modulated by the first baseband signal with its specific phase and reflected. The beamformed signals are generated by the plurality A of antennas by reflecting the modulated RF signals from each antenna.

摘要： A method is disclosed of generating a frequency shift keying (FSK) signal comprised in an orthogonal frequency division multiplexing (OFDM) signal comprising a plurality of sub-carriers. The FSK signal comprises FSK symbols wherein each FSK symbol has a corresponding FSK symbol frequency. The method comprises assigning (310) a set of adjacent sub-carriers to transmission of the FSK signal (wherein the set is a sub-set of the plurality of sub-carriers), and associating each FSK symbol frequency with a corresponding sub-carrier in the set of adjacent sub-carriers. The method also comprises selecting (330), for each FSK symbol (201, 202, 203) to be transmitted, an FSK symbol phase such that an FSK signal phase at a start (252) of the FSK symbol (202) to be transmitted meets a phase difference criterion in relation to the FSK signal phase at an end (251) of an immediately previous FSK symbol (201). The method further comprises generating (340) the FSK signal comprising the FSK symbol to be transmitted by modulating the sub-carrier corresponding to the FSK symbol frequency based on the selected FSK symbol phase and muting the remaining sub-carriers of the set. Corresponding arrangement, access point and computer program product are also disclosed.

摘要： Methods and systems for providing virtual beacons are presented. According to one aspect, a method for providing a virtual beacon at a first location comprises transmitting, by a transmitter at a second location geographically different from the first location, an information signal using a transmit power level, Pj, and including an advertised transmit power level, PA, both selected to be indicative of a distance, d, between a location of a receiver of the information signal and the first location. The signal transmitted from the second location emulates a signal that would have been produced by a beacon located at the first location. The information signals may be aimed at one or more User Equipments (UEs), and/or may be focused on one or more specific target locations rather than on individual UEs.

摘要： A link adaptation method is disclosed of a network node adapted to operate in concurrent association with one or more orthogonal frequency division multiple access (OFDMA) wireless communication devices using OFDMA signaling, and a non- OFDMA wireless communication device using non-OFDMA signaling. The non- OFDMA signaling has a bandwidth that is smaller than a maximum bandwidth of the OFDMA signaling. The method comprises excluding one or more sub-carriers from the OFDMA signaling to create a frequency gap and determining a center frequency of the non- OFDMA signaling such that the center frequency is within the frequency gap. The method also comprises selecting a modulation and coding scheme to be used for the OFDMA signaling based on a first signal-to-interference value. In the first signal-to-interference value, the non-OFDMA signaling acts as interference to the OFDMA signaling. Corresponding computer program product, arrangement and network node are also disclosed.

摘要： In one aspect, a transmitting device may frequency-division multiplex a wake-up signature (WUS) targeted to a wake-up receiver (WUR) of a receiving device with user data targeted to a main transceiver of each of one or more other receiving devices into an output signal. The output signal is then transmitted. A receiving device having a WUR and a main transceiver of the receiving device detects, at the WUR, a WUS targeted for the WUR in a received signal. The WUS is frequency-division multiplexed with user data for one or more other receiving devices in the received signal. The receiving device wakes up the main transceiver in response to the detecting.

摘要： A Transmitting Node (TN) 102 and a method therein for providing enhanced channel coding of a packet transmitted in a communications network 100. The TN applies, to payload data, an outer channel encoder resulting in a plurality of outer code bits. Further the TN applies an inner channel encoder to the plurality of outer code bits. Furthermore, the TN divides resulting code bits of the inner channel encoder into a first group and one or more second groups. Yet further, the TN generates a first set of OFDM symbols carrying at least a part of the first group, and second sets of OFDM symbols carrying at least a part of the one or more second groups. The TN transmits a packet comprising the first set of OFDM symbols followed by the second sets of OFDM symbols, whereby an enhanced channel coding of the transmitted packet is provided. A receiving node (RN) 104 and a method therein for enabling enhanced channel decoding of a packet transmitted in a wireless communications network 100, wherein a TN and the receiving node RN are configured to operate in the wireless communications network. The RN receives, from the TN, parts of a packet, which packet comprises a first set of Orthogonal Frequency-Division Multiplexing, OFDM, symbols followed by one or more second sets of OFDM symbols, wherein the first set of OFDM symbols carries at least a part of a first group of bits comprising bits of a first type, and wherein the one or more second sets of OFDM symbols carry at least a part of one or more second groups of bits comprising bits of a second type. When payload data is decodable from received parts comprising the first set of OFDM symbols, the RN decodes the payload data from the first set of OFDM symbols. When payload data is unsuccessfully decoded from received parts comprising the first set of OFDM symbols, the RN decodes the payload data from the first set of OFDM symbols and the one or more second sets of OFDM symbols, and the RN stops receiving parts of the packet when the payload data is decoded.

摘要： Embodiments herein relate to a method performed by a transmitting device (12) for transmitting information bits to a receiving device (10) in a wireless communication network (1). The transmitting device (12) encodes information bits of a first type of information and a second type of information into a codeword. The transmitting device (12) interleaves the encoded information bits of the first type of information according to a first interleaving pattern and the encoded information bits of the second type of information according to a second interleaving pattern, thereby changing an order of the encoded information bits of at least one of the first type of information and the second type of information in the codeword and generating an interleaved encoded information bit sequence. At least one of the first and the second interleaving pattern is designed to allow the information bits of a first type of information to be decoded without knowing a length of the codeword. The transmitting device then transmits the interleaved encoded information bit sequence to the receiving device (10).
