摘要： A method is disclosed for a wireless transceiver comprising a plurality of transceiver antenna elements and configured to operate in a communication network. The method comprises dynamically assigning (from the plurality of transceiver antenna elements) a first set of transceiver antenna elements allocated for channel sensing and a second set of transceiver antenna elements allocated for communication, performing channel sensing using the first set of transceiver antenna elements, and operating the wireless transceiver based on a result of the performed channel sensing. For example, dynamically assigning the first and second sets of transceiver antenna elements may comprise (in a non-communication mode of the wireless transceiver) letting the first set comprise all of the transceiver antenna elements and letting the second set be empty, (in a communication transmission mode of the wireless transceiver) letting the first set comprise a first subset of the transceiver antenna elements and letting the second set comprise a second subset of the transceiver antenna elements, wherein the first and second subsets are nonoverlapping, and (in a communication reception mode of the wireless transceiver) letting the first set comprise a third subset of the transceiver antenna elements and letting the second set comprise a fourth subset of the transceiver antenna elements, wherein the third and fourth subsets are non-overlapping or overlapping. Corresponding apparatus, wireless transceiver, access node, user device and computer program product are also disclosed.

摘要： Disclosed is a latency control method of a transmitter apparatus adapted for transmission of a plurality of packets under clear channel assessment requirements and latency requirements. The method comprises determining a maximum required time for clear channel assessment for the plurality of packets and determining a duration of time related to the determined maximum required time. For example, the duration of time may be determined as being equal to the determined maximum required time for clear channel assessment plus an offset. The offset may be equal to zero, or may be equal to a positive value. In some embodiments, the offset may be equal to, or larger than, a duration of another packet (which is not comprised in the plurality of packets). The method also comprises enforcing, for each packet of the plurality of packets, the determined duration of time to elapse after completion of transmission of the packet, before transmission of a subsequent packet of the plurality of packets is initiated. Corresponding latency control apparatus, transmitter apparatus, communication device and computer program product are also disclosed.

摘要： A transceiver device comprises a controller arranged to identify a first set of control information within the data packet, and to re-map the data packet such that the first set of control information is mapped on bits known to be more robust. The transceiver device further comprises a transmitter arranged to transmit the re-mapped data packet. The first set of control information holds information which enables for identification to combine soft bits from repeated transmissions at a receiver of the packet. The bits known to be more robust have more distinct value distribution in signal space of a used modulation and coding scheme than other bits. The transceiver device is arranged to transmit a data packet. A corresponding method, computer program, access point and station are also disclosed.

摘要： A method, network node and wireless device for generation of a high rate amplitude shift keying (ASK) signal are disclosed. According to one aspect, a method in a network node includes determining a first wake up signal, WUS, the first WUS being configured to indicate when the network node has data intended for the WD, the WUS having first information being embedded in an amplitude of the WUS. The method further includes modifying the first WUS to produce a second WUS, the second WUS having less energy leakage into at least one neighboring band of the first WUS than the first WUS. The method further includes multiplexing information data with the second WUS to produce a multiplexed signal, the information data being carried by sub carriers in the neighboring band of the first WUS, and sending the multiplexed signal to the WD.

摘要： A technique for transmitting data from a passive radio device (100) is described. As to a method aspect of the technique, an antenna (102) of the passive radio device (100) is exposed to an incident radio signal (502). A frequency domain representation of the incident radio signal (502) comprised at least one muted gap between active subcarriers within a bandwidth of the incident radio signal (502). The incident radio signal (502) is backscattered from the antenna by modulating an impedance of the antenna according to the data using at least two different modulation frequencies that differ by less than the bandwidth.

摘要： A method of a network node adapted to transmit a wake-up signal for waking up one or more wireless communication receivers is disclosed, as well as a method for the wireless communication receiver, such network node and wireless communication receiver, and computer programs for implementing the methods. Each wireless communication receiver is comprised in a wireless communication device and is associated with a wake-up radio adapted to wake up the wireless communication receiver in response to detecting the wake-up signal. An indication of a maximum frequency error of the wake-up radio associated with the wireless communication receiver is acquired such that a non-data transmission bandwidth for exclusive use by the wake-up signal can be determined. The wake-up signal is transmitted over a wake-up signal transmission frequency interval having a wake-up signal transmission bandwidth, wherein the wake-up signal transmission bandwidth is less than, or equal to, the non-data transmission bandwidth. The method of the wireless communication receiver comprises transmitting a message to the network node indicative of a maximum frequency error of the wake-up radio, wherein the maximum frequency error is for determination by the network node of a non-data transmission bandwidth for the exclusive use by the wake-up signal.

摘要： A transmitter 108 and a method therein for transmitting overlaid and underlaid signals to a narrowband receiver 112 and a wideband receiver 110. The transmitter and the receivers operate in a wireless communications network 100. The transmitter generates a narrowband signal carrying data for the narrowband receiver. The narrowband signal is generated by: mapping user code bits of the data to a first set of binary symbols; generating a second set of binary symbols by precoding the first set of binary symbols; rotating the binary symbols of the second set resulting in rotated constellation symbols; and filtering the rotated constellation symbols. Further, the transmitter generates a wideband signal carrying data for the wideband receiver. Furthermore, the transmitter overlays the generated narrowband signal over the generated wideband signal and transmits, to the narrowband receiver and the wideband receiver, the overlaid narrowband signal and the underlaid wideband signal, respectively.
