Abstract: The present document discloses methods, systems, and devices related to digital wireless communications, and more specifically, to techniques related to adjustable clear channel assessment for simultaneous transmission and reception constraint multi-link device. The method of the adjustable multi-link clear channel assessment includes adjustment of signal strength measurement algorithm or adjustment of energy detection threshold for the assessment when the multi-link network allocation vector is set for the transmission. A method for wireless communication includes identifying, by a wireless device, that a first wireless link and a second wireless link of the wireless device are in a detecting state at a first time. The method also includes modifying, by the wireless device, a multi-link channel availability assessment procedure of a second wireless link based on detecting a transmission state of the first wireless link at the first time.

Abstract: Provided are a transmission method, apparatus and system and a computer-readable storage medium. The 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. The lifetime is set for the automatic repeat request process so that the automatic repeat request process can be removed in time. In this manner, in the case where a limited number of automatic repeat request processes are simultaneously supported, a new automatic repeat request process can be created for a newly transmitted packet in time, and thus the transmission efficiency is improved.

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: The embodiments of the disclosure provides a method and device for processing the sending and receiving of service indication information, wherein the method is applied to an Access Point (AP) of a Wireless Local Area Network (WLAN). The method includes that sending time information of grouping indication information of Stations (STA) in the WLAN is acquired, wherein the sending time information is used for instructing the STAs to receive, according to sending moments indicated by the sending time information, service indication information corresponding to the STAs indicated by the grouping indication information; and the STAs indicated by the grouping indication information are notified of the sending time information. By means of the technical solution provided by the embodiments of the disclosure, the technical problems in the related art that sending of service indication information is not flexibly configured yet, it is necessary to monitor each wireless frame, and the like, are solved, thereby allowing service indication information (such as paging information of a group user) to be flexibly configured, sent and quickly acquired.
