Presented herein are techniques to facilitate extending a multiple access Protocol Data Unit (PDU) session and Access Traffic Steering, Switching, and Splitting Low-Layer (ATSSS-LL) policies to an enterprise network. In one example, a method may include obtaining a request for an ATSSS-LL policy for a user equipment (UE) for establishing a multiple access protocol data unit session for the UE via a wireless wide area access network for an enterprise network; and providing to the UE one or more ATSSS-LL rules for the ATSSS-LL policy, an Internet Protocol (IP) address for the multiple access protocol data unit session for the UE, and an identifier for the multiple access protocol data unit session for the UE in which the IP address is utilized for a wireless local area access network connection for the UE established via a wireless local area access network of the enterprise network.

A system and method for determining the presence of an individual at a particular spot within a location preferably based on the strength of signals received from beacons assigned to the particular spot by a software application (“App”) running on an electronic device of the individual. In one embodiment, certain presence calculations are performed by the App. In another embodiment, the App forwards information regarding the received beacon signals to an electronic identification and location tracking system and the presence calculations are performed by the system.

Certain embodiments provide a method of updating a security. The method can include monitoring a bearer that includes first and second radio accesses according to different radio technologies between user equipment and a communications network. One or more properties of the monitored bearer can be determined. An update of a security key utilized for securing communications over at least one of the radio accesses can be triggered in response to determining that the determined properties meet at least one triggering condition capable of indicating a need for the update.

Methods, systems, and devices relate to digital wireless communication, and more specifically, to techniques relating to dynamic change MAC address of the station for subsequent transmissions. In one exemplary aspect, a method of dynamic change MAC address includes specifying a MAC address change mode and a new MAC address to be used by the station. In another exemplary aspect, a method of dual MAC address change mode in the dynamic change MAC address mechanism includes separating the unchanged MAC address of the station from the changeable MAC address of the station, and keep the mapping between them. In another exemplary aspect, a method includes transmitting a MAC address change request message from the station (or the access point) to initiate the MAC address change procedure. In another exemplary aspect, a method includes receiving a MAC address change response message from the access point (or the station).

According to various embodiments, a receiving station (STA) may receive a physical protocol data unit (PPDU). The PPDU may include a legacy signal field, a repeated legacy signal field, a first signal field, and a second signal field. The receiving STA may determine a type of the PPDU and a format of the PPDU, based on the legacy signal field, the repeated legacy signal field, the first signal field, and the second signal field.

Proposed are a method and device for transmitting an EHT PPDU in a wireless LAN system. Specifically, a transmission device generates an EHT PPDU and transmits the EHT PPDU to a receiving device through a 320 MHz RF band. A legacy preamble includes an L-STF and an L-LTF. The legacy preamble is generated by applying a first phase rotation value. The first phase rotation value is determined on the basis of a first technique and a second technique. The first technique acquires an optimal PAPR in the L-STF and the L-LTF. The second technique acquires an optimal PAPR on the basis of the maximum transmission bandwidth supported by the RF. The first phase rotation value is acquired on the basis of a second phase rotation value and a third phase rotation value. The second phase rotation value is obtained by repeating a phase rotation value defined for an 80 MHz band in an 802.11ax system. The third phase rotation value is defined in 80 MHz band units in a 320 MHz band.
