    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.

    Abstract: A communications method is applied to a communications system including a backhaul node and a first wireless access device. The first wireless access device receives a first backhaul signal by using a first radio resource, and receives a first service signal by using a second radio resource. Herein, the first backhaul signal includes backhaul data sent by the backhaul node to the first wireless access device, the first service signal includes service data sent by a terminal to the first wireless access device, and the first radio resource is partially or completely the same as the second radio resource. Therefore, the first wireless access device may transmit the backhaul data and the service data on a radio resource.

    IPC: H04W74/08

    Abstract: A method for transmission and reception in parallel on dual channels includes, when detecting that a first channel is occupied by CSMA contention, determining, by an AP, first transmission duration of a first channel data packet. The method additionally includes determining, by means of CCA detection, that a second channel is idle, where the second channel is used to transmit a second channel data packet whose transmission direction is opposite to a transmission direction of the first channel. The method additionally includes determining, by using the first transmission duration, second transmission duration for transmitting the second channel data packet, and transmitting the second channel data packet according to the second transmission duration, where an end time of transmission of the second channel data is not later than an end time of transmission of the first channel data.
