摘要： A method of providing multi-link operation channel access in a multi-link network includes initiating a first backoff countdown and a second backoff countdown associated with a first link and a second link of the multi-link network, respectively, and in response to the first backoff countdown reaching zero, determining whether the second backoff countdown is less than or equal to an aggregation threshold, and in response to determining that the second backoff countdown is less than or equal to the aggregation threshold, transmitting a first frame and a second frame on the first and second links.

摘要： Systems and methods for providing feedback regarding a wireless communication channel is disclosed. A responding processor is configured to estimate condition of the wireless communication channel and generate a data field. The data field includes a communication parameter based on the estimated condition of the wireless communication channel. The data field is attached to a control frame, and the control frame is transmitted with the attached data field. A transmitting processor is configured to receive the control frame, and determine whether the control frame includes the data field. The transmitting processor retrieves the data field from the control frame, and selects, based on the communication parameter in the data field, a transmit parameter for transmitting data over the wireless communication channel.

摘要： A method for providing a mode of wireless local area network (WLAN) operation is disclosed. The method includes: sending an association request from a wireless station (STA) over a discovery channel; receiving an association response at the STA over the discovery channel in response to the association request; and associating the STA to provide a multi-user (MU) enhanced distributed channel access (EDCA) mode using a scheduled access channel.

摘要： A method for communicating over a WiFi channel. In some embodiments, the method includes determining, by a non-access point station, that a first skipping criterion is met; in response to determining that the first skipping criterion is met, skipping N1 target wait time service periods, N1 being a positive integer; after skipping N1 target wait time service periods, determining, by the non-access point station, whether a second skipping criterion is met; and in response to determining that the second skipping criterion is met, skipping N2 subsequent target wait time service periods, N2 being a positive integer greater than N1.

摘要： A method for encoding or transmitting. In some embodiments, the method includes forming a set of one or more unpunctured codewords by coding a plurality of payload bits at a mother code rate, removing a plurality of punctured bits from the set of one or more unpunctured codewords to form a set of one or more punctured codewords, and transmitting the set of one or more punctured codewords. In some embodiments, the number of punctured bits exceeds a first threshold, or the number of punctured bits exceeds a second threshold.

摘要： Methods and apparatuses are provided for a medium access protocol at non-simultaneous transmission and reception (STR) access points (APs) and end user devices (STAs). A method performed by a non-STR MAP includes identifying a medium state of a first channel of the MAP; and adapting transmission on a second channel of the MAP, based on the identified medium state of the first channel.

摘要： A system and method for dynamic access point (AP) selection by a station (STA) in a coordinated AP group is herein disclosed. According to an embodiment, a STA obtains one or more link quality metrics for each link between the STA and each of a plurality of member APs in the coordinated AP group. The STA dynamically selects at least one anchor AP for the STA from the plurality of member APs based on the one or more link quality metrics for each link. The at least one anchor AP being used to relay transmission between the STA and a coordinator of the coordinated AP group. Authentication of the STA with the at least one anchor AP is shared with all APs in the coordinated AP group, allowing the STA to utilize any subsequently selected anchor AP to relay transmissions without re-authentication.

摘要： A method and system for providing transitioning a station (STA) to an uplink multi-user (UL MU) disable mode and to a UL MU enable mode is provided. According to one embodiment, a method includes entering, with the STA, a UL MU enable mode, and determining whether to transition the STA to a UL MU disable mode based on a predetermined interrupt condition or actively monitoring conditions of the STA.

摘要： Methods and a devices are provided is for receiving simultaneous downlink transmissions at a mobile station (STA). Information regarding whether endings of simultaneous data transmissions to the mobile station are to be aligned is transmitted to an access point (AP). The simultaneous data transmissions are between the AP and the STA over a pair of channels. Reception begins of a first data transmission, from the AP, on a first channel of the pair of channels. Reception begins of a second data transmission, from the AP, on a second channel of the pair of channels. The second data transmission overlaps at least a portion of the first data transmission. Reception of the second data transmission ends upon an end of the first data transmission when the information indicates that the endings of simultaneous downlink data transmissions are to be aligned.
