Abstract: Disclosed are a physical layer (PHY) protocol data unit (PPDU) transmission method and a related apparatus. The method includes: generating a PPDU, where the PPDU includes a universal signal field (U-SIG), and the U-SIG includes a subfield indicating that the PPDU is a null data packet (NDP); and sending the PPDU. In this way, a beamformee (Bfee) that receives the NDP can identify the NDP earlier. This helps improve efficiency of reading the NDP by the Bfee. The PPDU is an NDP used for a standard after 802.11ax. In a scenario in which wireless communication is performed by using the standard (for example, 802.11be) after 802.11ax, the Bfee can perform channel estimation based on the NDP.

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 device resolves a collision between its transmission and a simultaneous transmission of another device. The device is configured to interrupt its transmission, determine a negotiation signal, and determine at least one available resource to occupy with the negotiation signal during a negotiation period. Further, the device is configured to transmit the negotiation signal on the at least one available resource and simultaneously receive a negotiation signal on another resource from at least one other device during the negotiation period. Then, the device is configured to decide, based on all negotiation signals, whether to retransmit the interrupted transmission after the negotiation period.

Abstract: A midamble indication method includes sending, by a first device, midamble indication information to a second device. A duration of a midamble indicated by the midamble indication information is greater than or equal to a threshold. The threshold is related to a processing capability of the second device. In a midamble receiving method, the second device receives the midamble according to the indication information.

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.
