Methods, apparatuses, and systems are disclosed for reducing latency during IRAT re-selection in the presence of race conditions. When a UE initiates an IRAT re-selection procedure, and concurrently initiates a call setup procedure, a race condition may result, in which the UE's NAS layer prioritizes the call setup procedure, while the RRC layer prioritizes the IRAT re-selection procedure. This may result in failure of the call setup procedure, which may lead to a user needing to re-initiate the call, resulting in poor user experience and significant latency. To prevent this, the UE may cache a message and/or other information relevant to the call setup procedure, until the IRAT re-selection procedure is complete. The UE may then proceed to complete the call setup procedure. The message may be cached, e.g., at the NAS layer or the RRC layer of the cellular modem, or by an application processor.

Methods and devices for providing normal and enhanced coverage cell selection and reselection capabilities, including the acquisition and monitoring of enhanced coverage information while camped on a cell in normal coverage, implementation of a threshold for a cell selection criteria prior to transitioning between normal and enhanced coverage while camped on a cell, and introduction of priority lists for cell reselection.

Devices and methods for normal and enhanced coverage compatibility

A mobile terminal device may include a radio processing circuit configured to transmit communication data indicating a serving cell, the communication data intended for a server and receive system information of one or more proximate cells of the serving cell indicated by the communication data. The mobile terminal device may also include a baseband processing circuit configured to determine if system information of a target cell is included in the received system information of the one or more proximate cells, and, if the system information of the target cell is included in the received system information of the one or more proximate cells, apply the received system information of the target cell to control the radio processing circuit to transmit or receive data.
