    Abstract: A signal transmission method and an apparatus are provided. The method includes: A sending device generates a sequence of a demodulation reference signal, and maps the sequence of the demodulation reference signal to a time-frequency resource of the demodulation reference signal for sending. The demodulation reference signal is used to estimate a channel state of a first channel, and the first channel carries uplink data. The time-frequency resource includes frequency-domain resources corresponding to a first CDM group, and the frequency-domain resources corresponding to the first CDM group are non-contiguous and equally spaced.

    Abstract: The present disclosure relates to techniques for forward error correction and packet padding in radio transmission, e.g. WiFi communication schemes such as IEEE 802.11ax and 802.11be. In particular, the disclosure relates to a communication device configured to: transmit and/or receive a data frame based on a set of pre&post-Forward Error Correction (pre&post-FEC) parameters and a set of packet extension (PE) parameters, wherein the set of pre&post-FEC parameters is based on an extension of a set of pre&post-FEC parameters defined for a second radio transmission technology with respect to a size of resource units (RUs) supported by a first radio transmission technology, wherein the set of pre&post-FEC parameters is based on a combination of RUs that is supported by the first radio transmission technology, and wherein the set of PE parameters is based on an extension of a set of PE parameters defined for the second radio transmission technology.

    Abstract: The present disclosure suggests to expand and improve the method of utilizing channel resources in the 802.11be standard by allowing the use of multiple and non-contiguous portions of a channel. Supporting multiple resource units (MRUs) and non-contiguous resource units (RUs) improves the channel utilization by making it more efficient due to enhancing the capability of leveraging the channel selectivity. To this end, a wireless network device for resource allocation is provided and configured to define a non-contiguous MRU in the bandwidth of the channel. The channel comprises a plurality of RUs, and the MRU is defined based on non-punctured RUs after puncturing one or more of the RUs of the channel, and/or is defined by aggregating two or more non-adjacent RUs of the channel.
