Abstract
Provided are a data sending feedback method and apparatus, and a data sending method and apparatus. According to data sending feedback method, when reception of a radio frame fails, a receiving station detects whether transmission of the radio frame over a specified sub-channel in a working channel ends within predetermined time; after the receiving station detects that the transmission of the radio frame over the specified sub-channel in the working channel ends within the predetermined time, the receiving station sends a feedback frame to a sending station of the radio frame.
Claims20
A data sending feedback method, comprising:
- when reception of a radio frame fails, detecting, by a receiving station, whether transmission of the radio frame over a specified sub-channel in a working channel ends within predetermined time;
- and
- after the receiving station detects that the transmission of the radio frame over the specified sub-channel in the working channel ends within the predetermined time, sending, by the receiving station, a feedback frame to a sending station of the radio frame;
- wherein detecting, by the receiving station, whether the transmission of the radio frame over the specified sub-channel in the working channel ends within the predetermined time comprises:
- receiving, by the receiving station, a physical preamble part of the radio frame over the specified sub-channel;
- parsing, by the receiving station, the physical preamble part to obtain a specified parameter;
- and determining, by the receiving station according to the specified parameter, whether the transmission of the radio frame over the specified sub-channel ends within the predetermined time, and determining, by the receiving station, that the receiving station is a target receiving station of the radio frame;
- or,
- wherein detecting, by the receiving station, whether the transmission of the radio frame over the specified sub-channel in the working channel ends within the predetermined time comprises:
- detecting, when the receiving station successfully decodes a physical preamble part of the radio frame over the specified sub-channel, a signal strength on the specified sub-channel;
- and judging, according to the signal strength, whether the transmission of the radio frame over the specified sub-channel ends.
