    Abstract: An electronic device that communicates frames is described. During operation, the electronic device may transmit the frames addressed to a recipient electronic device and associated with multiple links between the electronic device and the recipient electronic device. Then, the electronic device may receive block acknowledgments for at least a subset of the frames, where a given block acknowledgment is associated with the recipient electronic device and indicates received frames on a given link in the links. Moreover, the electronic device may control an amount of traffic conveyed on the links based at least in part on the block acknowledgments. Next, the electronic device may store a remainder of the frames based at least in part on the block acknowledgments, where the frames include the subset of the frames and the remainder of the frames. Note that the frames may have a common traffic identifier.

    Abstract: In order to eliminate the reliance of ultra-high bandwidth (UWB) standalone transceivers and narrow-band-assisted (NB-assisted) UWB transceivers on BLUETOOTH™ (BLE) usage, an NB radio may be used. The NB radio may be tightly coupled with the UWB radio, for example driven by the same time source, to enable leveraged use of ACP (Acquisition Packet) for discovery, session setup, and maintenance over UWB and/or NB-assisted UWB without the use of BLE. Rules for advertising ACP and scanning for ACP may be defined for two modes of operation. An ad-hoc discovery may be based on external acquisition triggers, while a managed discovery may be based on an ongoing discovery advertisement process. ACPs may thereby be transmitted over UWB and/or NB.

    Abstract: An electronic device (such as an access point) that receives one or more block acknowledgments is described. This electronic device may transmit an extremely high-throughput (EHT) physical layer convergence protocol (PLCP) protocol data unit (PPDU) to a recipient electronic device, where the EHT PPDU is transmitted in multiple non-contiguous sub-bands that are separated by a punctured sub-band. Moreover, the electronic may receive the one or more block acknowledgments from the recipient electronic device, where the one or more block acknowledgments exclude the punctured sub-band. Note that the EHT PPDU may exclude transmitted energy in the punctured sub-band. Moreover, the punctured sub-band may have a bandwidth of at least 20 MHz and may be different from a primary sub-band.
