    Abstract: The present document discloses methods, systems, and devices related to digital wireless communications, and more specifically, to techniques related to utilizing the multi-link channel assessment mechanism and multi-link channel access to reduce the access delay, improve transmission reliability, and increase transmission throughput. In one exemplary aspect, a method for wireless communication includes identifying, by a radio node, a first priority indicator associated with a data packet. The method also includes, responsive to identifying the first priority indicator associated with the data packet, transmitting, by the radio node, the data packet on a first available link detected via a multi-link clear channel assessment, the transmission of the data packet being prioritized to occur before transmission of another data packet that does not include the first priority indicator.

    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: The present document provides a method for avoiding downlink data collision, an Access Point (AP) and a Station (STA). The method for avoiding downlink data collision includes: an AP receiving a radio frame for inquiring whether the AP has a Bufferable Unit (BU) of an STA transmitted by the STA; and after determining that there is a BU of the STA and the BU is larger than a predetermined threshold, the AP exchanging radio frames with the STA to reserve a channel, and transmitting the BU to the STA after succeeding in reserving the channel. The method can guarantee the fairness among various STAs and the reasonable utilization of channel resources, thus avoiding the collision; furthermore, the channel reservation frame transmitted by the AP can reserve a longer period of time, i.e. a plurality of BUs can be transmitted to the STA at a time, thus saving the link overhead.

    Abstract: Provided are a radio frame sending method and apparatus. In the method, when entering an awake state from a doze state, a station selects a pre-defined access category or an access category which is pre-negotiated with a centre station to contend for a wireless channel. Afterwards, the station sends a radio frame to the centre station via the wireless channel obtained through the contention, and then notifies the centre station to send buffered data to the station. The method and apparatus can be applied to flexibly and dynamically regulate an access category used for contending for a wireless channel when a station sends a radio frame which is used for notifying a centre station to send buffered data to the station.
