Abstract: A method and device are provided for dynamic access point (AP) selection by a coordinator in a coordinated AP group. The coordinator of the coordinated AP group receives one or more link quality metrics for each link between a station (STA) and each of a plurality of member APs in the coordinated AP group, from the plurality of member APs. The coordinator selects an anchor AP for the STA from the plurality of member APs based on the one or more link quality metrics for each link. The anchor AP is used to relay transmissions between the STA and the coordinator. Authentication of the STA with the 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.

Abstract: A method of implementing a hybrid automatic repeat request (HARQ) process. The method includes: transmitting, by a transmitter to a receiver, an initial transmission of the HARQ process; receiving, by the transmitter from the receiver, receiver decoding capability information; setting, by the transmitter, a retransmission duration based on the receiver decoding capability information; and implementing, by the transmitter, a retransmission of the HARQ process based on the retransmission duration.

Abstract: A method of implementing a hybrid automatic repeat request (HARQ) process. The method includes generating a HARQ transmission that comprises one or more HARQ units by: determining a HARQ unit size of the one or more HARQ units; generating the one or more HARQ units by assigning to each respective HARQ unit, based on the HARQ unit size, at least a respective portion of a media access control (MAC) layer data unit; and generating a header for the HARQ transmission. The method further includes transmitting the HARQ transmission to a receiver. The one or more HARQ units are physical layer data units.

Abstract: 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.

Abstract: Systems and methods for managing use of power of a wireless communication device configured to communicate over a plurality of radio links. A criterion is detected, and one of the plurality of radio links is selected as a selected radio link based on detecting the criterion. Operation of the selected radio link is switched from a first operating mode to a second operating mode, and operation of one or more remaining radio links of the plurality of radio links is disabled. In response to switching operation of the selected radio link to the second operating mode, the selected radio link oscillates between an awake state and an asleep state. Radio traffic information for the plurality of radio links is received, via the selected radio link, during the awake state.

Abstract: 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.

Abstract: 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.
