Abstract: Embodiments of the present invention are drawn to systems, apparatus and methods that provide TSF information for a non-primary link to a non-AP STA operating on a primary link to avoid IDC interference and improve wireless throughput and efficiency. The TSF information includes a TSF offset value used to determining the timing of subsequent transmissions over different wireless links. The TSF offset value can be carried in a beacon frame, probe response frame, association frame, through a Reduced Neighbor Report element or a multi-link element, for example. Beacon frames can include timestamp and TSF offset information transmitted periodically. Some wireless links may share a TSF clock or have fixed TSF offsets.

Wireless communications are then established with one or more stations (STAs) over a plurality of links.

The fragmented frames can be received by a wireless device and defragmented according to the MF field, the PF field, and the sequence control number. The frames can be discarded if any are not received successfully.

Abstract: A first access point (AP), which is affiliated with a AP multi-link device (MLD) operating on a non-simultaneous-transmission-and-reception (NSTR) link pair comprising a primary link and a non-primary link, generates a beacon frame or probe response frame. The first AP then transmits the beacon frame or probe response frame on a link that is not the non-primary link to indicate that a second AP affiliated with the NSTR AP MLD and operating on the non-primary link is unavailable, quiet or disabled.

Abstract: A station (STA) affiliated with a non-simultaneous-transmission-and-reception (NSTR) multi-link device (MLD) obtains a transmission opportunity (TXOP) on a first link of an NSTR link pair as a TXOP initiator while a medium synchronization delay timer of the STA is non-zero. STA determines that an intended TXOP responder has lost medium synchronization. The STA then transmits a control frame as an initial frame in the TXOP to the intended TXOP responder on the first link responsive to the determining.

Abstract: Embodiments of the present invention provide systems, apparatus and methods that provide transmission information of different APs to a wireless device during link discovery. The transmission information is used to determine AP coverage/link reachability information for performing channel association, channel switching, multi-AP coordination, or groupcast transmission and reception, for example. The transmission information can correspond to APs affiliated with the same AP MLD or APs affiliated with different AP MLDs. In this way, wireless devices can identify a link with sufficient coverage according to reachability information determined for different APs without having to scan each BSS directly, which advantageously reduces power consumption and improves wireless network performance.

Abstract: Embodiments of the present invention provide apparatus and methods for announcing a BSS parameter updates for a wireless link that can be received by a MLD even when the MLD is not listening for parameter updates on that specific link by employing a different wireless link to broadcast, receive, and/or signal the BSS parameter update. An MLD can update the BSS parameters of the wireless link and use the wireless link according to the updated BSS parameters (e.g., after performing a channel switch). According to some embodiments, an STA within an AP MLD transmits an information elements (IE) including BSS parameter updates associated with a different STA (operating on a different wireless link) within the AP MLD.

Abstract: Embodiments of the present invention provide A TID-based RTWT SP that can be configured for either trigger-based transmission or EDCA-based transmission for time sensitive traffic to reduce the chance of contention/collision on time sensitive traffic caused by non-time sensitive traffic using an EDCA mechanism. This can also reduce the chance of contention on time sensitive traffic when both trigger-based transmission and EDCA-based-transmission are used in the same TID-based RTWT SP. The AP MLD can dynamically adjust the schedule of TID-SPs for ether trigger-based or EDCA-based transmission and announce the new schedule of the TID-SPs according to the requirements of time sensitive traffic and/or traffic load condition, and can prioritize time sensitive transmission to meet QoS requirements.

Abstract: A user equipment (UE) is described. The UE includes transmitting circuitry configured to transmit a demodulation reference signal (DMRS) for a physical uplink shared channel (PUSCH).
