Abstract: Some embodiments enable improved aggregated throughput and average latency in a wireless communication channel. Wireless electronic devices may implement adaptive contention window (ACW) channel access that improves channel capacity and enables latency sensitive applications (e.g., video streaming), especially when all wireless electronic devices operating on the channel as well as those in proximity utilize ACW channel access. Some embodiments detect when wireless stations on the communication channel as well as wireless stations in proximity are utilizing ACW channel access to obtain a transmit opportunity (TXOP). Based on the detection, an access point (AP) can instruct an associated wireless station to: use ACW channel access to obtain a TXOP, use a different channel access method obtain a TXOP as needed, disassociate and associate with a different AP, or use a different channel access method to obtain a TXOP.

Abstract: An interface circuit in an electronic device (such as an access point) may utilize a configurable wake-up-frame format. During operation, the interface circuit may receive a wake-up-radio (WUR)-setup request associated with a recipient electronic device, where the WUR-setup request specifies a proposed configurable wake-up-frame format. In response, the electronic device may determine the configurable wake-up-frame format to be used based at least in part on the proposed configurable wake-up-frame format. Then, the interface circuit may provide a WUR-setup response intended for the recipient electronic device, where the WUR-setup response specifies the configurable wake-up-frame format selected for use. Note that the configurable wake-up-frame format may specify a payload length in a wake-up frame and/or one or more operations of at least one of the recipient electronic device or the electronic device after the wake-up frame is transmitted by the electronic device.

Abstract: An interface circuit in an electronic device (such as an access point) may provide a wake-up beacon to a recipient electronic device. During operation, the interface circuit may provide a wake-up beacon associated with a predefined sub-channel in one or more channels in a band of frequencies, where the wake-up beacon is for a wake-up radio in the recipient electronic device. Moreover, the wake-up beacon may be provided within an associated time interval, such as a keep-alive interval of the electronic device. In some embodiments, the wake-up beacon includes a field with channel information that specifies one or more second channels used by a main radio in the recipient electronic device. Alternatively or additionally, the wake-up beacon may include a field with service information that specifies one or more types of services and/or a field with information specifying a transmit power of the interface circuit.

Abstract: Embodiments described herein relate to a system and method for improving a rate of success in receiving response packets, such as 802.11 Acknowledge (ACK), Block Acknowledge (BACK), and Clear-To-Send (CTS) packets. In one embodiment, a wireless device may transmit one or more first packets according to a wireless communication protocol, and may then receive a second packet. The wireless device may determine that the receiving follows the transmitting by a specific duration of time that is specified by the wireless communication protocol for a response packet to follow one or more communication packets to which it responds. Based at least in part on this determining, the wireless device may further determine that the second packet is a response packet responding to the one or more first packets, without decoding a portion of the second packet that identifies a packet type of the second packet.

Abstract: Embodiments may relate to group addressed frame delivery over multi-link systems. Systems and methods are configured for identifying, by an access point (AP) multilink device (MLD) in a wireless network, a first sequence number space (SNS) that is to be used by the AP MLD to transmit data to a non-AP MLD over a first communications link and a second communications link, wherein frames with identical data that are transmitted over the first and second communications links will have an identical first SN based on the first SNS; identifying, by the MLD in the wireless network, the first SN based on the first SNS; and transmitting, by the AP MLD in the wireless network, a frame that includes the data to the non-AP MLD based on the first SN.

Abstract: Methods for performing negative acknowledgements (NACKs) in a Wi-Fi based network may include a wireless device receiving, from a neighboring wireless device, a transmission schedule associated with receipt of data packets from the neighboring wireless device. The transmission schedule may include a timeout period associated with transmission of the data packets and/or a start time of the transmission schedule. The method may also include the wireless device determining an error condition associated with the data packets. The error condition may be, for example, non-receipt of any packet (e.g., data packets and/or non-data packets) prior to expiration of the timeout period and/or detection of a gap in sequence numbers associated with the data packets. The method may further include the wireless device, based on the error condition, transmitting a NACK. The NACK may be (or include) a negative block ACK (N-BA) bitmap indicating which data packets were not successfully received.

Abstract: The subject technology provides for block acknowledgment requests and block acknowledgment frames that can be used in conjunction with multicast transmissions that include multiple concurrent streams. Thus, the subject technology reduces the overhead associated with multicast transmissions that include multiple concurrent streams by aggregating the acknowledgments across multiple streams into a block acknowledgment, thereby increasing the effective throughput of such transmissions and overall network efficiency.
