Techniques for managing access combinations for multiple access protocol data unit (PDU) sessions are described. A communication device may receive control signaling indicating a configuration for a multiple access PDU session associated with a plurality of access links. The plurality of access links may be associated with a first type of access, a second type of access, or a combination thereof. The communication device may select a mode for allocation of a data flow associated with the multiple access PDU session to the plurality of access links based at least in part on the received control signaling. The communication device may allocate the data flow associated with the multiple access PDU session to the plurality of access links based at least in part on the selected mode, and transmit the allocated data flow over the plurality of access links associated with the two types of access.

A wireless device sends, to an access and mobility management function (AMF) of a 5G system (5GS) network, a registration request message to register the wireless device in the 5GS network. The wireless device receives, from the AMF, a registration accept message comprising an access traffic steering, switching, and splitting (ATSSS) capability indication of the 5GS network. The ATSSS capability indication indicates whether an ATSSS feature is supported by the 5GS network. The wireless device sends, to the AMF of the 5GS network and after receiving the registration accept message, a packet data unit (PDU) session establishment request message comprising a request for a PDU session.
