Question: What does a value of '1' for a bit in the TRS availability indication field signify to a UE in RRC_IDLE or RRC_INACTIVE state regarding associated TRS resource sets?
Option 1: Immediate activation of all TRS resource sets for a single frame.
Option 2: Presence of associated TRS resource sets for a multiple of frames, starting from a determined System Frame Number (SFN).
Option 3: No change to the current paging cycle configuration for the UE.
Option 4: Deactivation of all TRS resource sets until further notice.
Explanation: A value of '1' in the bitmap indicates the presence of associated TRS (Transmission Reception Resource Set) resource sets, valid for a multiple of frames starting from a determined System Frame Number (SFN), allowing the UE to anticipate and prepare for upcoming TRS resources over a defined period.
