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 first radio device (20) receives a first radio transmission (101) from a second radio device (10). In response to reception of the first radio transmission (101) by the first radio device (20) being unsuccessful, the first radio device (20) sends a second radio transmission(103) to the second radio device (10). The second radio transmission (103) comprises an indication to the second radio device (10) that reception of the first radio transmission (101) by the first radio device (20) was unsuccessful. The first radio device (20) generates the second radio transmission (103) to be decodable by one or more other radio devices (30) than the second radio device (10) as comprising a positive acknowledgement message, indicating to the second radio device (10) that reception of the first radio transmission (101) by the first radio device was successful (20), as comprising a clear-to-send message to the second radio device (10), or as some other legacy message supported by the other radio device(s) (30).

摘要： A wireless communications system (110) and a method for frequency multiplexing a first (LAA) OFDMA transmission and a second (Wi-Fi) OFDMA transmission on a shared radio channel spanning at least partly a common bandwidth. The system determines an unallocated frequency band available beside a first frequency band intended for a first transmission and sends a sharing request comprising information about the unallocated band. The system decides to use the unallocated band in a second frequency band in the shared channel. The system sends a legacy preamble and a first part of a Wi-Fi preamble spanning the shared channel. The first transmission is sent in the first band such that an end time point of the first part of the Wi-Fi preamble coincides with a start time point of the first transmission. Further, the system sends a second part of the Wi-Fi preamble and the second transmission in the second band.

摘要： A process for selecting frequency channel(s) used by a network node (20) operating in an unlicensed band is disclosed. To that end, a network node (20) analyzes a signal received for each of multiple frequency channels using autocorrelation techniques, and thus without first demodulating the signals, to determine what types of wireless communication devices (32) are contributing to the load of each frequency channel. The network node (20) then selects one of the frequency channels for scheduling communications in the unlicensed band with a wireless communication device (30), where the selection is responsive not only to the estimated load, but also to the identified types of other wireless communication devices (32).

摘要： Determining timing of an OFDM signal comprises performing (610) an auto-correlation with a received signal, using a delay chosen to correspond to the duration of an OFDM symbol excluding the cyclic prefix, with the number of terms used in the summation in the correlation is at least as large as the smallest number of samples in any cyclic prefix of a subframe. Based on the auto-correlation, first and second correlation peaks meeting one or more predetermined detection criteria are detected (620), and evaluated to determine (630) that they are separated in time by an interval corresponding to an OFDM symbol interval. The method further comprises identifying (640), based on the two correlation peaks, one of the correlation peaks as corresponding to an OFDM symbol having a larger cyclic prefix than an adjacent OFDM symbol, and determining (650) a subframe and/or slot timing for the received signal, based on said identifying.

摘要： An Access Point (AP) 402 and a method therein for Multi-User Clear-To-Send (MU CTS) signaling between the AP and at least one wireless station (STA) 404,406. The AP sends a Request To Send (RTS) packet directed to multiple STAs. The RTS packet is indicating at least two STAs, to which the AP would like to transmit, and a configuration of a CTS packet to be used by said at least two STAs when responding to the RTS packet. The configuration enables the AP to identify the at least two STAs when the at least two STAs are transmitting a respective CTS packet. Further the AP receives, from at least one STA, a respective CTS packet transmitted in accordance with the indicated configuration, thereby enabling the AP to identify the at least one STA transmitting the respective CTS packet.

摘要： A network node is arranged to provide communication at least in an unlicensed band where clear channel assessment, CCA, is required before transmissions. The unlicensed band comprises a plurality of carriers, or sets of carriers, defining channels. The network node is arranged to prepare code block groups comprising code blocks from transport blocks, which transport blocks each comprises a payload intended for a respective receiver, wherein each code block comprises a checksum enabling a hybrid automatic repeat request, HARQ, procedure on a per code block group basis, map the code block groups to a wideband signal comprising a consecutive set of channels on the carriers of the unlicensed band, assess whether the channels, respectively, are clear, and transmit the code block groups mapped on the channels which are clear and omit transmissions of code block groups mapped on channels that are not clear, wherein the assessment and the transmissions are performed within a first time interval, and transmit code blocks groups omitted to be transmitted using the HARQ procedure for retransmission prior receiving a non-acknowledgement, NAK, from a respective

摘要： The present disclosure relates to methods and arrangements for determining a next interlace to be applied during a next transmission interval for a transmission in an unlicensed spectrum. A method for determining a next interlace having a next structure to be applied during a next transmission interval is disclosed. The next structure is to be applied for a transmission over a wireless interface in a wireless communications network operating in an unlicensed spectrum, wherein a first interlace is applied during transmission in a first transmission interval and wherein the first interlace has a first interlace structure formed by a plurality of physical resource blocks, PRBs, that are arranged with a given subcarrier spacing in one of a set of interlaces. The method comprises defining (S21) a frequency shift based on the number of PRBs per interlace and a maximum allowed power for a single interlace and determining (S22) the next interlace structure by shifting the first interlace structure by the defined frequency shift. A corresponding reception method, arrangements for performing the methods and computer program products are also disclosed.
