Question: During a PDCP (Packet Data Convergence Protocol) entity reconfiguration for releasing Dual-Active Protocol Stack (DAPS), what happens to the state variables controlling transmission and reception operations?
Option 1: They are reset to default values to ensure a clean slate for new configurations.
Option 2: They are partially updated based on the new configuration, with some being reset.
Option 3: They are not reset, and associated timers (e.g., t-Reordering, discardTimer) continue running.
Option 4: Their handling is left entirely up to the UE (User Equipment) implementation specifics.
Explanation: This is correct because, according to PDCP reconfiguration guidelines for releasing DAPS, state variables controlling transmission and reception operations should not be reset. Timers like t-Reordering and discardTimer keep running during the PDCP entity reconfiguration procedure, ensuring operational consistency and preventing potential data loss or misordering.
