Abstract: An embodiment is a method performed by a wireless device to provide header protection for a physical layer protocol data unit (PPDU). The method includes generating a hash value of header information of the PPDU by applying a hash function to the header information of the PPDU, including the hash value in an encrypted payload portion of the PPDU, and transmitting the PPDU with the hash value included in the encrypted portion of the PPDU. An embodiment is a method performed by a wireless device to verify the integrity of header information of a received PPDU. The method includes extracting header information of the PPDU, extracting a first hash value included in an encrypted payload portion of the PPDU, generating a second hash value by applying a hash function to the extracted header information, and discarding the PPDU if the second hash value does not match the first hash value.

Abstract: Coordinated spatial reuse and frequency utilization techniques in overlapping basic service set environments for IEEE 802.11be and beyond. The techniques involve transmit power and frequency allocation methods designed for coordinated spatial reuse between multiple access points, considering interference from stations and access points, as well as occupied bandwidth. In one embodiment, an access point generates a trigger frame with punctured bandwidth or good subchannel information to coordinate spatial reuse, enabling a station to transmit an uplink data packet using specified parameters. In another embodiment, a station receives a trigger frame with punctured bandwidth information and transmits an uplink data packet excluding the puncture portion to avoid interference. The techniques allow transmissions in multiple basic service sets to coexist without harmful interference, improving throughput and frequency utilization in dense wireless networks. Although primarily described in the context of IEEE 802.11, the techniques can be applied to other wireless networks.

Abstract: A new enhanced Multi-User (MU) Request-to-Send (RTS) Transmit Opportunity Sharing (TXS) frame and solutions for handling unavailable resource units (RUS) at a shared access point (AP) side. A sharing AP can allocate a portion of its RUs and TXOP to shared APs, facilitating C-TDMA coordination and reducing resource waste. The disclosed solutions focus on efficiently handling unavailable RUs at the shared AP side during the allocated TXOP sharing time. When a shared AP cannot fully utilize the allocated RUs due to interference, it can return the interfered RUs to the sharing AP or assign them to another shared AP. By dynamically managing and reallocating interfered RUs, the disclosed solutions optimize resource utilization, minimize waste, and increase overall system throughput in high-density wireless networks.
