Abstract: Embodiments of the present invention provide a punctured preamble enabling wireless devices to efficiently use a channel (e.g., an 80 or 160 MHz channel) where a primary service is operating. A Wideband Channel Access Mechanism for 20 MHz/80 MHz operating STAs is provided so that a 20 MHz/80 MHz operating STA can dynamically move to a secondary channel to improve wireless performance of the STA. An AP coordinates the operating channel switch of the 20 MHz/80 MHz operating STA. An EHT cooperative multi-band operation can be applied to the preamble punctured PPDU for simultaneous multi-band operation.

Abstract: A method for coordinating beacon transmission times for a plurality of access points (APs) in a wireless local area network includes generating a first neighboring AP list listing one or more neighboring AP(s) of a first AP, deriving a first beacon transmission time for the first AP according to the first neighboring AP list, and transmitting a beacon message at the first beacon transmission time by the first AP. The first AP and the one or more neighboring AP(s) are arranged to form a Hot Spot that offers network services over the wireless local area network.

Abstract: The disclosed invention provides an efficient method for beam training to enable spatial multiplexing MIMO operation and spatial combining in a wireless network. The invention discloses a simple and efficient beam-training algorithm and protocol for MIMO operation that operates in high SNR condition for reliable MIMO operation. In one novel aspect, the best MIMO beam combinations are determined after TX sector sweeping and RX sector sweeping. In addition, the selection criteria includes not only signal quality, but also considers mutual interference and leakage among multiple MIMO spatial streams to improve overall MIMO performance.
