    Abstract: A device for a wireless network is disclosed. The device is configured to perform an access method, using a plurality of nodes, to gain access to a medium of the wireless network, wherein each node is associated with a different channel of the medium and the access method is performed by using separately each node. The device is further configured to transmit data using an active node that has gained access to the medium. Moreover, the device is further configured to, if another node also gains access to the medium after a determined time period from the access of the active node, control the active node to release the medium and to start the access method again, and control the other node to start transmitting data.

    Abstract: The present invention relates to Hybrid Automatic Repeat Request, HARQ, in wireless communication technologies, particularly HARQ for IEEE 802.11, i.e. HARQ for Wi-Fi. To this end, the invention proposes a transmitting device and a receiving device, respectively, both configured to support such HARQ in Wi-Fi. The transmitting device is configured to: encapsulate a data unit in a container unit, encode the container unit into a codeword set of one or more codewords. Accordingly, the receiving device is configured to receive from the transmitting device at least one codeword set of one or more codewords, decode the codewords of the codeword set to obtain a container unit, and decapsulate the container unit to obtain a data unit. Thereby, a bit-size of the container unit is equal to the bit-size of the codeword set in the transmitting device and receiving device.

    Abstract: A device for determining a received signal as minimum values of a set of values, the device comprising a processor configured to: load a first set of values in a register; identify a maximum value of the first set of values and a minimum value of the first set of values; in the register, replace the maximum value by a value of a second set of values and simultaneously replace the minimum value by a new value, calculated based on the minimum value, to receive an updated first set of values; and repeat previous steps until all values of the updated first set of values are replaced by values of the second set of values.

    CPC classification number: H04L27/2626

    Abstract: An access point device and method for wireless communication comprising: a transmitter configured to allocate a dedicated low-band channel (DLBC) in an Orthogonal Frequency Division Multiple Access (OFDMA) wireless frame structure (ODFMA-WFS), the DLBC has a lower bandwidth than a required minimal bandwidth of the OFDMA-WFS, and a modulator configured to produce in the DLBC a low-band signal field (LBSF) detectable in said lower bandwidth, for acquiring data symbols transmitted in the dedicated low-band channel. Further, a communication device and method comprising: a signal sensor configured to detect a low-band signal in the DLBC and to trigger a receiver to start receiving and decoding transmission in the DLBC, wherein the receiver is configured to receive and decode LBSF in the DLBC and to acquire data symbols transmitted in the DLBC based on information decoded from the LBSF.
