Abstract: Embodiments of a wireless device and methods for rekeying with reduced packet loss in a wireless network are generally described herein. In some embodiments, during rekeying operations a new key for reception may be installed early (i.e., prior to receipt of a rekeying confirmation message). The use of the new key for transmission may be delayed until after receipt of the rekeying confirmation message. The early installation of the new key for reception may allow both the new key and old key to be active at the same time for use decrypting received packets to reduce packet loss during rekeying operations. The rekeying confirmation message may be the fourth message of a four-way handshake for rekeying. In some embodiments, two key identifiers may be alternated between four-way handshakes to prevent deletion of the old key.

Abstract: Wireless device, method, and computer readable media for channel contention in wireless communication devices. The wireless communication device may include hardware processing circuitry configured to: determine to adapt the channel contention, and configured to adapt the channel contention settings by changing a level of a clear channel assessment (CCA) and adapting at least one additional channel contention setting. The hardware processing circuitry may be configured to adapt the channel contention settings by raising a level of the clear channel assessment (CCA) and by decreasing a power used to transmit, raising a back-off time, or modifying a portion of or parameter to a distributed coordination function (DCF). The hardware processing circuitry may be configured to adapt the channel contention settings by decreasing the clear channel assessment (CCA) and increasing a power used to transmit or decreasing an amount of time to wait after a CCA determines the channel is free.

Abstract: An extremely high-throughput (EHT) station (STA) is configured for transmission of a control response frame for rate selection. In response to a frame carried in an EHT PPDU soliciting a control response frame, the EHT STA may calculate a duration of a non-HT PPDU containing the control response frame sent at a primary rate, The EHT STA may also encode a high-efficient (HE) single-user (SU) PPDU (HE SU PPDU) for transmission to carry the solicited control response frame when a transmit time of the encoded HE SU PPDU is less than the calculated duration of the non-HT PPDU, or encode an EHT PPDU for transmission to carry the solicited control response frame when a transmit time of the encoded EHT PPDU is less than the calculated duration of the non-HT PPDU. A reduction in overhead may be achieved by using an HE SU PPDU or an EHT PPDU instead of a non-HT PPDU to carry a solicited control response frame.
