    Abstract: A method for transmitting information, a station, and an access point in a MU-MIMO system includes: determining, by a first station, multiple to-be-sent first long training sequences, where the multiple first long training sequences include at least one pilot for phase tracking; and sending, by the first station, the multiple first long training sequences to an access point on multiple symbols, where a second station sends multiple second long training sequences to the access point on the multiple symbols, the multiple second long training sequences include at least one pilot for phase tracking, and a first pilot for phase tracking and a second pilot for phase tracking occupy different time-frequency resources, where the at least one pilot for phase tracking included in the multiple first long training sequences includes the first pilot for phase tracking.

    Abstract: Embodiments provide a resource scheduling method, which can support reduction of transmission resource overheads in resource scheduling. The method is applied to a wireless local area network, where a next generation protocol followed by the wireless local area network predefines locations of resource units possibly allocated from a to-be-assigned frequency domain resource. The method includes: generating, by a sending end, resource scheduling information, where the resource scheduling information includes a bit sequence to indicate an actual allocation of a resource unit(s) from the to-be-assigned frequency domain resource, and at least some bits in the bit sequence are to indicate whether one or more of said resource unit locations possibly allocated for the to-be-assigned frequency domain resource is\are the actually allocated resource unit(s).

    Abstract: The disclosure discloses a high-efficiency short training field sequence generation method, a signal sending method, a signal receiving method, and related apparatuses, where the high-efficiency short training sequence generation method includes: increasing frequency domain density of a frequency domain sequence corresponding to a first high-efficiency short training field sequence to generate a frequency domain sequence with increased frequency domain density; generating a second high-efficiency short training field sequence according to the frequency domain sequence with increased frequency domain density; and using the second high-efficiency short training field sequence as a high-efficiency short training field sequence in a preamble sequence of a data transmission frame in a wireless local area network WLAN. In embodiments of the disclosure, a cycle of a high-efficiency short training field sequence used for performing stage-2 AGC adjustment in the WLAN may be increased, and a maximum CSD value that can be used is further increased.

    Abstract: A pilot sequence sending method and apparatus are provided. In the disclosure, after first-time masking is performed on a pilot sequence based on a cyclic orthogonal matrix, second-time masking is performed on the pilot sequence on which first-time masking has been performed, so that a PAPR of the pilot sequence on which second-time masking has been performed is less than a PAPR of the pilot sequence on which first-time masking has been performed, and further, orthogonality of the pilot sequence on which second-time masking has been performed can be higher than that of the pilot sequence on which first-time masking has been performed. This ensures accuracy of channel estimation and frequency offset detection.
