Abstract: A microcell creating method based on macrocell network coverage and a base station are disclosed. The method may include setting a beam width and a beam direction of a highly directional antenna according to location information of a hotspot area, and generating microcell coverage or the hotspot area by using beams generated by the highly directional antenna. Embodiments of the present invention may keep the micro base station location unchanged when the hotspot area changes, and may implement microcell coverage for the hotspot area simply by adjusting the beam width and the beam direction of the highly directional antenna.

Abstract: A parallel transmission method and apparatus to improve channel resource utilization are described. A first configuration parameter for a first access point is configured by a WLAN control device. A second configuration parameter for a second access point is configured by the WLAN control device. The first configuration parameter is used to indicate that the first access point can send a first WLAN frame to at least one station in a first station set at a starting time by using a channel resource. The first station set includes one or more stations associated with the first access point. The second configuration parameter is used to indicate that the second access point can send a second WLAN frame to at least one station in a second station set at the starting time by using the channel resource. The second station set includes one or more stations associated with the second access point.

Abstract: Embodiments of the present invention disclose a data processing method and apparatus, and belong to the field of communications technologies. The method includes: generating a physical layer protocol data unit PPDU, where the PPDU includes a preamble field, a data field, and a middle preamble field, and the preamble in the PPDU includes information used to indicate an insertion frequency of the middle preamble in the data field in the PPDU; and sending the PPDU. The insertion frequency of the middle preamble in the data field is indicated by using a specified field in the preamble. In this way, in different scenarios, the middle preamble may be inserted into the data field at different frequency, thereby reducing overheads of an inserted pilot and improving data transmission performance.
