Proposal on database Collection for Scenarios 9 and 10
Source: Beijing Xiaomi Mobile Software Co., Ltd
Meeting: SA4 #135-bis-e, April 2026
Background: Scenario 3 databases have been completed and submitted. Reuse of Scenario 3 recordings to construct Scenarios 9 and 10 (as discussed since SA4#135) remains unresolved, with no party assigned responsibility for construction/editing.
Proposal 1: Allow individual proponents who require Scenarios 9 and 10 to independently generate those databases using single-source recordings, rather than relying on a centrally coordinated effort. A note to this effect is proposed for addition to DaCAS-1 clause 4.3.3.2 (Mandatory recording scenarios).
Proposal 2: Move Scenarios 9 and 10 out of the "Required Recordings" category, reducing the mandatory burden on the overall database collection process while keeping them available for interested proponents.
Rationale: Removes a coordination bottleneck, streamlines database collection, and gives proponents flexibility without blocking progress on the wider activity.
Conclusion: Requests agreement on adding the clarifying note to DaCAS-1 §4.3.3.2 and reclassifying Scenarios 9 and 10 as non-required.
