Abstract: This disclosure provides methods, components, devices and systems for performing actions to protect a wireless access point (AP) from repeated incorrect security credential input attacks. For example, a combination of techniques are implemented to block a wireless station (STA) from submitting innumerable number of incorrect security credential inputs to connect to the wireless AP by using embargo lists to block the wireless STA media access control (MAC) address after N number of consecutive unsuccessful attempts to connect to the wireless AP, using telescopic delays to make it progressively harder for the wireless STA to attack (that is, repeatedly submit incorrect security credential inputs) at regular short intervals, and/or determining position of the wireless STA of the attacker and then block attacks from all wireless STAs at the determined location.

Abstract: This disclosure provides methods, components, devices, and systems for securing frames. In some examples, a frame is transmitted with a field that includes an identifier (ID) of a security key, a packet number (PN), and an integrity check based on one or more portions of the control frame and the security key. A device receiving the frame can verify the frame by calculating another integrity check based on the frame and the identified security key and comparing the calculated integrity check to the received integrity check.

Abstract: An access point (AP) may prioritize the allocation of uplink resources between multiple basic service sets (BSSs). In some aspects, the AP may select one of a plurality of BSSs, may allocate one or more random-access resource units (RUs) to only the selected BSS, and may transmit, for each of the selected BSSs, a respective frame indicating the random-access RUs allocated to that BSS. Wireless devices belonging to the selected BSS may contend for access to the random-access RUs allocated by the frame, and then transmit uplink data using the random-access RUs.

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: Certain aspects of the present disclosure provide methods and apparatus for using a block acknowledgement (BlockAck) frame capable of acknowledging fragments. One example method for wireless communications generally includes receiving a plurality of protocol data units (PDUs) (e.g., media access control (MAC) protocol data units (MPDUs)); determining whether each of the PDUs was successfully received and whether each of the PDUs is associated with a non-fragmented service data unit (SDU) (e.g., MAC service data unit (MSDU)) or a fragmented SDU; and outputting for transmission a BlockAck frame comprising a bitmap field indicating a receive status for the non-fragmented and fragmented SDUs based on the determination.

Abstract: In some embodiments, a method includes processing, at a communication device, a packet received via a communication media. The method also includes reducing, while the packet is being processed, power to at least one component in the communication device, in response to a condition associated with the processing of the packet being satisfied. The method includes restoring power to the at least one component prior to receiving an entirety of the packet at the communication device.
