Abstract
A method for indicating transmission of a buffered downlink data frame under multi-connection. An access point generates a message frame including first information and second information, and sends the message frame to a station. The first information is configured to indicate that a downlink data frame of the station is buffered at the access point, and the second information is configured to indicate the station to receive the downlink data frame buffered by the access point under multi-connection. A method for receiving a buffered downlink data frame under multi-connection is also disclosed.
Claims16
A method for indicating transmission of a buffered downlink data frame in multi-link, comprising:
- generating, by an access point, a message frame containing first information and second information, wherein the first information is configured to indicate that a downlink data frame for a station is buffered by the access point, and the second information is configured to instruct the station to receive the downlink data frame buffered by the access point in multi-link;
- wherein link capability indication field of the message frame comprises a plurality of bits, the plurality of bits are associated with the multi-link respectively, and each bit indicates whether data transmission is available on a corresponding link;
- and
- sending, by the access point, the message frame;
- wherein the multi-link corresponds to different bandwidths in different frequency bands.
A method for receiving a buffered downlink data frame in multi-link comprising:
- receiving, by a station, a message frame containing first information and second information;
- wherein link capability indication field of the message frame comprises a plurality of bits, the plurality of bits are associated with the multi-link respectively, and each bit indicates whether data transmission is available on a corresponding link;
- and
- receiving, by the station, a downlink data frame buffered by an access point in multi-link based on the second information, in response to the first information indicating that the downlink data frame for the station is buffered by the access point;
- wherein the multi-link corresponds to different bandwidths in different frequency bands.
An access point, comprising:
- an antenna;
- a memory;
- and
- a processor, connected to the antenna and the memory respectively, and configured to control the antenna to transmit and receive radio signals by executing computer-executable instructions stored on the memory, to implement a method for indicating transmission of a buffered downlink data frame in multi-link, the method comprising:
- generating a message frame containing first information and second information, wherein the first information is configured to indicate that a downlink data frame for a station is buffered by the access point, and the second information is configured to instruct the station to receive the downlink data frame buffered by the access point in multi-link;
- wherein connection link indication field of the message frame comprises a plurality of bits, the plurality of bits are associated with the multi-link respectively, and each bit indicates whether data transmission is available on a corresponding link;
- and
- sending the message frame;
- wherein the multi-link corresponds to different bandwidths in different frequency bands.
