Wireless communications systems and methods related to user equipment (UE) idle mode mobility in a wireless communication network are provided. A wireless communication device establishes a network session with a wireless communication network. The wireless communication device reselects a first cell for camping, wherein the first cell is associated with the wireless communication network. The wireless communication device monitors for first system information from the first cell. The wireless communication device reselects a second cell for camping in response to a failure to receive the first system information. The second cell is associated with the wireless communication network and different from the first cell. The wireless communication device maintains the network session during the reselecting the first cell for camping and the reselecting the second cell for camping.

Increase in-service time and robustness for sustained mobility in idle mode

Wireless communications systems and methods related to improving user equipment (UE) mobility performance are provided. A wireless communication device camps on a first cell operating on a first carrier frequency. The wireless communication device receives, from the first cell, cell selection priority information indicating a priority for each of a plurality of carrier frequencies. The wireless communication device evaluates each of two or more candidate cells over an evaluation time duration associated with each candidate cell, wherein an end time of the evaluation time duration of a candidate cell associated with a lower priority carrier frequency is configured to be after an end time of the evaluation time duration of a candidate cell associated with a higher priority carrier frequency. The first wireless communication device selects a second cell from the two or more candidate cells for camping based at least in part on the evaluation of the second cell.
