At a glance
Architecture work spans migration, the data framework, QoS, sensing, and new study descriptions. Migration discussions include a proposed dual registration variant framed around a RAN requirement. The data framework discussion includes a proposal for the UE to act as both data producer and consumer. Separate work on mobile burst application traffic raises extended transmission after PSDB expiry. These proposals sit alongside substantial QoS and sensing agendas within the architecture study.

Study on Architecture for 6G System (FS_6G_ARC) - Migration and Interworking
Significance 47 of 100, 46 TDocs
A dual registration contribution proposes adding a solution variant to meet a RAN requirement. The variant is a proposal for discussion, not an agreed migration design. Its focus is narrower than the full migration and interworking study. The discussion can therefore address both the stated requirement and how the proposed variant relates to the wider architecture work.
Study on Architecture for 6G System (FS_6G_ARC) - 6G data framework in SA2
Significance 35 of 100, 137 TDocs
A data framework contribution proposes treating the UE as both a data producer and a data consumer. The proposal draws on identified use cases and places particular weight on extensibility. That makes the UE's role a concrete question for the framework discussion. The proposed treatment covers both directions of data use rather than assigning the UE only one of those roles.
Proposal: Considering the currently identified use cases and, more importantly, extensibility, it proposes to treat the UE as data consumer and data producer of the ...

New Study/Work Item Descriptions
Significance 33 of 100, 12 TDocs
A new study discussion addresses mobile burst application traffic in 5G-Advanced. Its contribution requests extended transmission when the PSDB has expired, considering PDU Set Importance. This is a proposed treatment of that traffic condition, not a group decision. The specific condition links the transmission request to both PSDB expiry and PDU Set Importance.
