    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: A communication method includes a first communication device that sends, to a second communication device, a physical layer protocol data unit (PPDU) including indication information and M link adaptation blocks, where the indication information indicates a resource used for link adaptation, the M link adaptation blocks use different transmission parameters, and the resource is used to transmit the M link adaptation blocks. The second communication device returns, to the first communication device, a feedback result determined based on a measurement result corresponding to the M link adaptation blocks, so that the first communication device sends, based on the feedback result, a PPDU used for data transmission. Hence, the two communication devices complete link adaptation through one interaction, and do not need to perform a plurality of interactions.

    Abstract: This application relates to the field of wireless fidelity technologies, and in particular, to a resource indication method, an access point, and a station. The method includes: An access point generates a PPDU, and sends the PPDU, where the PPDU comprises a preamble puncturing information field; and where when the PPDU is in non-orthogonal frequency division multiple access (non-OFDMA) transmission mode, the preamble puncturing information field is used to indicate a puncturing status of an entire bandwidth corresponding to the PPDU; when the PPDU is in an orthogonal frequency division multiple access (OFDMA) transmission mode, the preamble puncturing information field is used to indicate a puncturing status of 80 MHz corresponding to a frequency domain fragment.

    Abstract: In a demodulation reference signal (DMRS) configuration method, a network device sends first scheduling information to a terminal device. The terminal device determines, based on the first scheduling information, whether a transmission of a first time unit meets a condition of having the same transmit power, same precoding, same antenna port, or a same frequency domain resource as the transmission of a second time unit. The second time unit is before the first time unit and has a transmission direction that is the same as a transmission direction in the in the first time unit, and no transmission in an opposite direction exists between the second time unit and the first time unit. When the first time unit meets the above condition, the terminal device sends uplink data in the first time unit and the second time unit, or receiving downlink data in the first time unit and the second time unit.
