Abstract: Decoding failure and throughput loss are reduced when a user equipment (UE) tunes away from a first radio access technology (RAT) to a second radio access technology. In one instance, the UE determines when one or more receive chains will tune away from a first subscriber identity module (SIM) to another SIM. The UE reports a channel state based on measurements obtained without the one or more receive chains during the determined tune away and/or during a predetermined time period before the determined tune away. The UE also reports the channel state based on measurements obtained with the one or more receive chains after the one or more receive chains return from the determined tune away.

Abstract: A user equipment (UE) periodically suspends communications on a first radio access technology (RAT) to redirect another communication or initiate the other communication on a second RAT. In one instance, the UE suspends an application running on the first RAT before switching to the second RAT. Prior to returning from the second RAT to the first RAT, the UE ranks frequencies of the first RAT in an acquisition history based on a type of a suspended application in the first RAT, and characteristics of each frequency in the acquisition history. The UE then search one or more frequencies in the acquisition history in accordance with the ranking.

Abstract: A multi-subscriber identity module (SIM) user equipment (UE) reduces call interruptions caused by tuning away. In one instance, the user equipment determines whether to abort a tune away procedure to a second subscriber identity module at the user equipment. The determination is based on a type of procedure running on a first subscriber identity module at the user equipment and/or a characteristic of an intended tune away to the second subscriber identity module.

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) 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.
