Abstract: Some embodiments of this disclosure include apparatuses and methods for implementing block acknowledgment (BA) operations for multi-link wireless communication networks. For example some embodiments relate to an electronic device including a transceiver and one or more processors communicatively coupled to the transceiver. The one or more processors transmit, using the transceiver and to a second electronic device, a first set of one or more frames on a first link and a second set of one or more frames on a second link. The one or more processors receive, using the transceiver and from the second electronic device, a first block acknowledgment (BA) frame on the first link and a second BA frame on the second link. The one or more processors further determine, based on received first BA frame and the second BA frame, a failed or missing frame of the first set of one or more frames transmitted on the first link.

Abstract: Disclosed herein are system, method, and computer program product embodiments for identity obscuration of a station (STA) connected to a wireless network to prevent the tracking of the STA. Embodiments include a STA configured to establish a security association with an access point (AP) based on an original long term identity for the station and an identity of the AP. The STA can transmit a new long term identity for the STA to the AP based on the security association. The STA can then transmit a request frame to change the original short term identity assigned to the STA to the AP. The STA can receive a response frame from the AP. The response frame can include a new short term identity assigned to the station by the AP. The STA can then map its new long term identity to its new short term identity assigned by the AP.

Abstract: Some aspects of this disclosure include a system, apparatus, article of manufacture, method, and/or computer program product and/or combinations and/or sub-combinations thereof, for implementing multi-credential mapping mechanisms in wireless communication networks, such as a wireless local area network (WLAN). The multi-credential mapping mechanisms can use pointer schemes for communicating multiple credentials (e.g., Authentication and Key Managements (AKMs) and ciphers) in the wireless communication networks. The multi-credential mapping mechanisms can reduce congestion in the communication medium and improve the communications between an access point (AP) and stations (STAs).

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: Systems, methods, and mechanisms for an out-of-band (OOB) ultra-wide band (UWB) channel arbitration and/or channel coordination scheme. A device may scan an arbitration channel for a first time period, and based on the scanning, determine that the arbitration channel is not in use. The device may perform, on the arbitration channel, a first channel access procedure and perform, on the UWB channel, UWB communications during a UWB channel transmission opportunity.

Abstract: Some embodiments include an apparatus, method, and computer program product for access point (AP) power save enhancements. AP power save enhancements reduce power consumption for APs including multi-link device (MLD) APs, mobile APs and mobile AP stations. Some embodiments include an uplink (UL) multi-user (MU)-Request to Send (RTS) power save feature, that allows an AP to be available while operating in a low power receive (LPR) state (e.g., low power mode) and transition to a full power mode to receive data using a bandwidth greater than 20 MHz. Some embodiments include a Target Wake Time (TWT) UL MU-RTS AP power enhancement feature that allows an AP to operate in the LPR during a TWT service period (SP). Some embodiments allow mobile devices (e.g., a smart phone) to operate in as an AP (e.g., a mobile AP, a mobile AP station) and reduce power consumption.

Abstract: Some embodiments include an apparatus, method, and computer program product for access point (AP)-assisted AP transition. Using AP-assisted AP transitions, when the STA is associated with a first access point (AP) and is transitioning to a second AP, a station (STA) can transmit to the second AP a control signal including a first indication for sequence number (SN) maintenance. The STA can receive from the second AP responsive to the first indication for SN maintenance, a first downlink (DL) transmission including a next SN. The next SN can be a continuation of an SN sequence utilized by the first AP for one or more previous DL transmissions.

Abstract: A wireless device may transmit ranging transmissions using a compressed PSDU. The compressed PSDU may be configured to support poll packets, response packets, and report packets. The compressed PSDU may comprise an identifier (ID) field, an address field, ID specific data, and a cyclic redundancy check (CRC) field. Further, the wireless device may use an optimized header IE for broadcast.
