Abstract: A transmission method includes creating an automatic repeat request process for a first packet; setting a lifetime for the automatic repeat request process; and sending the first packet; and when a preset retransmission condition in the lifetime of the automatic repeat request process is satisfied, retransmitting a second packet; where the preset retransmission condition includes that at least part of the time instants within the first predetermined time interval after an incorrect-reception acknowledgement frame returned by the receiver is received is beyond the lifetime of the automatic repeat request; where retransmitting the second packet includes: extending the lifetime of the automatic repeat request process to a third predetermined time interval following the first predetermined time interval, where the third predetermined time interval is at least a time period required for retransmitting the second packet; and retransmitting the second packet after the first predetermined time interval.

Abstract: Provided are a method for implementing an automatic retransmission function and a related station. The method includes that a first station sends a first message. The first message carries automatic retransmission enable information. The automatic retransmission enable information is used for instructing that the automatic retransmission function be enabled or disabled.

Abstract: The present invention relates to wireless communication technology, and particularly relates to a signal transmission method and a communication device. The signal transmission method includes: transmitting, by a first communication node, a signal on one or more first channels located in a primary transmission channel and/or a secondary transmission channel of the first communication node, and before transmitting the signal, performing channel protection on a transmission channel where the first channel is located and/or the primary transmission channel. Correspondingly, further provided is a communication device.

Abstract: Provided is a channel access method. The method includes: after a radio frame is received, determining that the radio frame is an overlapping basic service set (OBSS) radio frame; determining that the OBSS radio frame is a radio frame of a specified type or determining whether the OBSS radio frame carries specific spatial multiplexing instruction information; updating a local network allocation vector according to duration information carried in the OBSS radio frame; and performing channel access according to the local network allocation vector. Provided are a channel access device and a storage medium.

Abstract: A method for processing a network allocation vector (NAV) includes: terminating the receiving of a first radio frame when it is determined that a target receiving station of the first radio frame being received is not a first station; and updating an NAV of the first station or maintaining the NAV of the first station unchanged according to a remaining duration of the first radio frame and a first transmission opportunity duration carried in the first radio frame, where the remaining duration of the first radio frame is the transmission time used for transmitting the remaining part of the first radio frame after the receiving of the first radio frame is terminated. The technical solution solves the problem in the related art of collisions with hidden stations caused by an inaccurate NAV update in the existing art, thereby ensuring the accuracy of an NAV update and the fairness of transmission and channel contention, and reducing collisions among hidden stations.

Abstract: Provided are a data sending and receiving method and apparatus and a storage medium. The methods include sending a wireless signal that includes a trigger frame to one or more second communication nodes. The trigger frame is configured to trigger one or more second communication nodes to start transmission. The wireless signal carries at least one of first identifier information, second identifier information or third identifier information. The first identifier information is used to identify the sender of the trigger frame. The second identifier information is used to identify the receiver of the trigger frame. The third identifier information is used to identify that the trigger frame is configured to trigger the second communication node to start transmission.
