  • Publication number: 20240155722
    Abstract: A first policy control function (PCF) in a first network node may receive an indication from a session management function (SMF) that a protocol data unit (PDU) session is an alternative PDU session, and an indication of whether the PDU session is in a drop state. The first PCF may send a message with an indication to a second PCF in a second network node to indicate that the network node is serving a PDU session that is an alternative PDU session. In an example, the message with an indication to the second PCF may also identify the PDU session. The first PCF may receive a message from the second PCF with an indication that a second PDU session has experienced a fault or degraded performance. Further, the first PCF may send a message to the SMF to change the PDU session to a no-drop state.

  • Publication number: 20240147370
    Abstract: Methods and apparatuses are described herein for chained and delayed wake-up. For example, a station (STA) may determine, at the formation of a group of STAs, a common service period for the group. The STA may determine a deferral time for a first STA of the group. The deferral time may indicate when the first STA wakes up to receive a wake-up packet. The STA may receive, from an access point (AP), during a service period in which the STA acts as a head node for communication with the AP, a wake-up packet addressed to the first STA. The STA may transmit, based on a determination that the deferral time associated with the wake-up packet addressed to the first STA ends after the service period in which the STA acts as a head node, a wake-up command that includes the wake-up packet addressed to the first STA.
