    摘要： A signal field indication method and apparatus are provided, so that a SIG-A can transmit more information bits. The method includes: generating, by a transmit end, a PPDU, where the PPDU includes a SIG-A indication field, and the SIG-A indication field includes at least one of a field used to indicate a number of SIG-A information symbols and a field used to indicate a SIG-A information bandwidth; and sending, by the transmit end, the PPDU. According to the method provided in this application, the transmit end may indicate different numbers of SIG-A information symbols and/or different SIG-A information bandwidths.

    摘要： This application discloses midamble indication and receiving methods and apparatuses. In the method, a first device sends midamble indication information to a second device, where a duration of a midamble indicated by the midamble indication information is greater than or equal to a threshold, and the threshold is related to a processing capability of the second device; and the second device receives the midamble according to the indication information. In the foregoing method, the first device sends the midamble indication information to the second device, so that the second device can receive the midamble according to the indication information. Furthermore, a duration of processing the midamble does not significantly increase as the duration of the midamble increases. Therefore, the fact that the duration of the midamble is greater than or equal to the threshold helps avoid a case in which after receiving the midamble, the second device may have no time to correctly decode a data symbol based on the midamble due to the limited processing capability.

    摘要： Embodiments of the present invention provide a method for transmitting a physical layer protocol data unit PPDU, including: some data subcarriers of a last orthogonal frequency division multiplexing OFDM symbol that carries useful information and that is in the PPDU carry a data symbol sequence, the other data subcarriers of the last OFDM symbol that carries useful information carry a feature signal sequence, and a starting position of the feature signal sequence is determined by parsing the PPDU. The embodiments of the present invention further provide a corresponding PPDU transmission apparatus. Application of the method and apparatus in the embodiments of the present invention enables a receive end to quickly determine the starting position of the feature signal sequence by means of blind detection, and ensures that the receive end quickly completes data processing and state switching.

    摘要： A transmitter of an Access Point (AP) for transmitting Physical Layer Protocol Data Units (PPDUs) over an increased number of channel groups each comprising multiple sub-channels, comprising a circuitry configured to encode a high efficiency signal (HE-SIG) field comprising a common signal field, HE-SIG-A, to indicate which of a plurality of sub-channels is active for transmitting a current PPDU and transmit the HE-SIG-A in a preamble of the current PPDU transmitted to one or more stations (STAs) the current PPDU is transmitted on the active sub-channels. Wherein the plurality of sub-channels are arranged in a primary channel group comprising a primary sub-channel and three secondary sub-channels and three secondary channel groups, each of the three secondary channels comprises four secondary sub-channels.

    摘要： 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 (RUs) of a channel. Supporting MRUs and non-contiguous 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.
