    Abstract: A method for wireless communication may include receiving a communication and determining an acknowledgement signature for an acknowledgment in response to the communication. The acknowledgment signature may allow for authentication with the transmitting wireless device. The acknowledgment signature may be based on a key shared with the wireless device. An acknowledgement frame ( e.g. , acknowledging reception of the communication) may then be sent to the transmitting wireless device. The content of the acknowledgement may be based on the acknowledgement signature. For example, the signature may be included in a frame control, duration, or address field. Determining the acknowledgement signature may include determining a unique signature based on information from the received communication ( e.g. , a cyclic redundancy check (CRC)), the shared key, and/or a hash function. In some cases, the acknowledgement frame may include an encryption header, and a message integrity check may be included as the acknowledgement signature.

    Abstract: A method includes receiving, at a first device, a packet from a second device. The method also includes detecting receipt of the packet at a detection circuit. The method further includes, in response to detecting the receipt of the packet, capturing a time of arrival timestamp corresponding to the packet at a capture circuit. The method also includes receiving, at the first device, a time of departure timestamp corresponding to the packet from the second device. The time of departure timestamp indicates a time when the packet is sent from the second device. The method further includes performing a comparison of the time of arrival timestamp and the time of departure timestamp.

    Abstract: A wireless device (e.g., a station (STA)) may receive a transmission soliciting a control transmission (e.g., a soliciting transmission). The STA may identify a transmission parameter indicator, which may indicate a change in one or more parameters in a control response transmission parameter set (e.g., a set of parameters used for control transmissions in response to the soliciting transmission). The STA may transmit the control transmission in response to the soliciting transmission based on the identified transmission parameter indicator. The control response transmission parameter set may include a frame format, a physical layer convergence protocol (PLCP) protocol data unit (PPDU) format, a bandwidth, a modulation scheme, an encoding scheme, a modulation and coding scheme (MCS), a number of spatial streams (NSS), and/or a PPDU duration. In some cases, the transmission parameter indicator may indicate disabling or resumption of extended range (ER) single user (SU) PPDU format usage.

    Abstract: This disclosure provides methods, devices and systems for acknowledgement and retransmission, and more specifically, to methods, devices and systems that enable a secondary wireless channel to provide acknowledgements of data transmitted on a primary wireless channel concurrently with the reception of additional data on the primary wireless channel. In some implementations, a transmitting device may transmit wireless packets including multiple codewords to a receiving device via a first wireless channel. The receiving device may attempt to decode the received codewords based on primary information in the codewords. The receiving device may then transmit to the transmitting device, via a second wireless channel, a codeword acknowledgement that identifies codewords that the receiving device did not successfully decode. The transmitting device may then transmit parity information to the receiving device via the first wireless channel that aids the receiving device in decoding the identified codewords.

    Abstract: Systems and methods are provided for preferentially locating a candidate channel likely to have an active network during a WLAN scanning process of an increased bandwidth. The candidate channel may be detected using spectral analysis of a received signal that may involve any combination FFT captures and correlation operations associated with detecting packets. Upon identification of a candidate channel, a wireless communications device may switch to that channel to receive and process one or more packets to determine the existence of a BSS available for association.

    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be communicating on a radio frequency spectrum band of a first radio access technology (RAT) using a set of antennas. The UE may determine, for at least one antenna of the set of antennas, that a demand requirement associated with the communications is below a threshold level and reconfigure, based at least in part on the demand requirement, the at least one antenna of the set of antennas to perform communications on the radio frequency spectrum band of a second RAT. Also, the UE may identify a time period associated with a rank mode modification schedule used for communications on a radio frequency spectrum band of a first RAT, identify a burst communication requirement on the radio frequency spectrum band of a second RAT, the burst communication requirement comprising a duration that is shorter than the time period associated with the rank mode modification schedule and reconfigure, based at least in part on the duration being shorter in time, at least one antenna of a set of antennas to perform burst communications during the duration on the radio frequency spectrum band of the second RAT.
