Abstract: The present application provide a resource allocation method, an access point, and a station. The method includes: determining a resource allocation sequence of N stations in a wireless local area network and a position of a resource allocated to each station in the N stations; determining resource allocation information according to the resource allocation sequence of the N stations and the position of the resource allocated to each station in the N stations, where the resource allocation information is used to reflect a relative position of the resource allocated to each station in the N stations; and sending resource indication information, so that each station in the N stations obtains, according to the resource indication information, the position of the resource allocated to each station. The method utilizes redundancy between indication information of different stations, so signaling overheads of resource indication information can be reduced.

Abstract: A data transmission method and a communication apparatus to improve transmission timeliness. In a wireless local area network, one channel transmission opportunity is obtained by an access point AP through contention. The AP sends service data to a station STA, and the STA feeds back a first data frame in which an error occurs in the service data to the AP. The AP sends scheduling information on a downlink channel to notify the STA of a retransmission resource unit used for retransmission of the first data frame, and retransmits the first data frame on the retransmission resource unit. Correspondingly, the STA receives the first data frame on the retransmission resource unit.

Abstract: The disclosure relates to an information indication method, an information receiving method, and an apparatus. The information indication method includes: sending, by an access point, a data frame to at least one station, where the data frame is a non-aggregated frame or an aggregated frame obtained by aggregating N MAC frames, N is a positive integer greater than 1 and is less than or equal to M, and M is a maximum allowable quantity of aggregated MAC frames; sending, by the access point, trigger information to the at least one station, where the trigger information is used to instruct the at least one station to reply with an acknowledgement frame on a shared resource unit; and receiving, by the access point, the acknowledgement frame fed back by the at least one station on the shared resource unit.

Abstract: This application provides example data retransmission methods and communication apparatuses. One example method includes receiving a physical protocol data unit (PPDU) by a first device and from a second device, where the PPDU includes a signaling field and a data field, the data field includes retransmitted data and newly transmitted data, the signaling field includes first indication information, or the signaling field comprises the first indication information and second indication information, the first indication information indicates a first modulation and coding scheme (MCS) and a first coding mode that are used for the newly transmitted data, and the second indication information indicates a second MCS and a second coding mode that are used for the retransmitted data. The PPDU is demodulated based on the signaling field.

Abstract: The present disclosure relates to data transmission method and apparatus. One example method includes generating and sending a link aggregation request, where the link aggregation request is used to request to perform transmission of a same type of data stream over a plurality of links, receiving a link aggregation response, where the link aggregation response represents whether the transmission of the same type of data stream over the plurality of links is accepted or not, and performing data transmission based on the link aggregation response.
