Abstract: A session management function (SMF) sends, to an access and mobility management function (AMF), one or more first messages indicating user plane connection activations for a plurality of packet data unit (PDU) sessions to deliver downlink user data to one or more wireless devices. The SMF receives, from the AMF, a first time duration based on the user plane connection activations for the plurality of PDU sessions. The first time duration indicates a delay between receiving a downlink data packet and notifying the AMF about user plane connection activation for the downlink data packet. The SMF sends, to a user plane function, a second message to delay sending of further user plane connection activations to the SMF. The second message indicates a value of the first time duration.

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 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.
