Abstract: In one instance, a user equipment (UE) determines, at an application layer, an application activity that triggers a service request before data arrives at a buffer of the UE. In response to the determining, the UE may send, from a NAS layer (non-access stratum layer), the service request to a base station requesting one or more radio bearers for one or more service contexts when no radio bearer is assigned for the one or more service contexts. Alternatively, the UE may send a schedule request from a lower layer than the NAS layer when the radio bearer is already assigned before data arrives at the buffer of the UE.

Abstract: In one instance, a base station configures a first set of UEs, served by a serving base station, with a first IRAT measurement reporting threshold (inter-radio access technology measurement reporting threshold). The base station also configures a second set of UEs, served at the serving base station, with a second IRAT measurement reporting threshold that differs from the first IRAT measurement reporting threshold when a number of UEs served by the serving base station exceeds a congestion threshold.

Abstract: A method, a computer-readable medium, and an apparatus for switching between a first radio access network (RAN) using the first radio access technology (RAT) and the second RAN using a different, second RAT are provided. The method includes switching a wireless device operating at a first signal frequency in the first RAN to a second RAN and switching from the second RAN back to the first RAN. In an aspect, the wireless device is switched to one of the cells operating at the first signal frequency in the first RAN if each signal parameter from the one of the cells satisfies a criterion. The wireless device is otherwise switched to another one of the cells operating at a second signal frequency in the first RAN based on parameters from the another one of the cells. The first signal frequency is different from the second signal frequency.

Abstract: In a method and system for wireless communication, a user equipment (UE) determines a signal quality of a serving cell of the first RAT and a signal quality of neighbor cells of the first RAT are all below a first threshold. The UE selects a first target cell of the second RAT for a synchronization channel decoding procedure when the signal qualities are all below the first threshold. The UE prevents switching the synchronization channel decoding procedure from the first target cell of the second RAT to a second target cell of the second RAT, during a measurement procedure and after an inter-radio access technology (IRAT) measurement of the measurement procedure. The UE prevents the switching when a difference between a signal quality of the first target cell and a signal quality of the second target cell is below a second threshold.

Abstract: A method of wireless communication at a user equipment (UE) includes initiating a procedure for a circuit switched fall back (CSFB) service in response to a mobile originated voice call or a mobile terminated voice call in a radio access technology (RAT) not supporting circuit switched voice calls. The method further includes determining whether a time to trigger (TTT) timer has expired for a measurement report configured to trigger a handover to a target cell. The method also includes determining whether the target cell is of a RAT supporting circuit-switched voice calls. If so, sending of the measurement report is delayed, i.e., when the RAT of the target cell does not support circuit-switched voice calls.

Abstract: A user equipment (UE) improves measurement procedures during a communication cycle, such as a connected mode discontinuous reception cycle (C-DRX cycle). In one instance, the UE enters a C-DRX off duration during a C-DRX cycle of an ongoing communication. The UE then stops background activity until a start of a C-DRX on duration of a next C-DRX cycle when a signal quality of a serving radio access technology (RAT) is below a predefined threshold.

Abstract: A method of wireless communication at a user equipment (UE) includes determining whether a user equipment (UE) is traveling faster than a predetermined speed and determining whether a current serving frequency is dedicated, based on whether the UE is traveling faster than the predetermined speed and/or whether a high-speed flag is set in a received message. The method also includes periodically searching a dedicated frequency from a dedicated frequency list to detect a dedicated cell with a signal quality above a predetermined threshold and switching to the dedicated cell, when the signal quality of the dedicated cell is above the predetermined threshold.

Abstract: A user equipment (UE) reduces latency during a redirection procedure, such as a circuit-switched fallback (CSFB) procedure. In one instance, the UE searches and measures each frequency of a received redirection list of frequencies to determine a strongest frequency. The UE decodes a system information block (SIB) from one or more non-strongest frequencies. The UE then determines whether to wait for a system information block from the strongest frequency based on a metric. The UE determines which of the one or more non-strongest frequencies are selected based on the metric when deciding not to wait for the system information block from the strongest frequency.
