DATA TRANSMISSION METHOD AND COMMUNICATION APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18353554 titled 'DATA TRANSMISSION METHOD AND COMMUNICATION APPARATUS
Simplified Explanation
The patent application describes a method and apparatus for improving data transmission timeliness in a wireless local area network.
- The access point (AP) obtains a transmission opportunity through contention in the network.
- The AP sends service data to a station (STA).
- The STA provides feedback to the AP by sending a first data frame that contains an error in the service data.
- The AP sends scheduling information on a downlink channel to notify the STA of a retransmission resource unit for retransmitting the first data frame.
- The AP retransmits the first data frame on the retransmission resource unit.
- The STA receives the retransmitted first data frame on the retransmission resource unit.
Original Abstract Submitted
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.
