    Abstract: This disclosure provides systems, methods, apparatuses and computer-readable medium for wireless communication. In some aspects, a user equipment (UE) may receive, from a first base station (BS) associated with a fifth generation New Radio (5G NR) radio access technology (RAT), a command of mobility from the 5G NR RAT to a second RAT. The UE may determine that the command of mobility is for voice fallback. The UE may transmit, to a second BS associated with the second RAT and based at least in part on determining that the command of mobility is for voice fallback, a radio resource control (RRC) connection request communication for attempting to communicatively connect with the second BS for voice fallback.

    Abstract: A user equipment (UE) avoids or reduces a “ping pong” scenario when the UE repeatedly transitions between a current serving cell and one or more previous serving cells of a dedicated network in high speed scenarios. In one instance, the UE determines whether a target cell for handover or cell reselection of the UE is one of N previous serving cells, when the UE is in the high speed scenario. The UE also increases a cell reselection threshold and/or measurement reporting threshold for handover or reselection when the target cell is one of the N previous serving cells. The UE can also adjust a measurement frequency of the previous N serving cells when in a high speed state. New neighbor cells will not have their threshold or measurement frequency adjusted.

    Abstract: A user equipment (UE) reduces latency of measurement procedures when the UE leaves a coverage area of a serving radio access technology (RAT) and enters a coverage area of a neighbor RAT. In one instance, the UE performs inter-RAT measurements of neighbor frequencies of the neighbor RAT during a measurement gap allocated by a base station of the serving RAT. The UE also determines whether to switch a frequency of the neighbor RAT for decoding a synchronization channel during the measurement gap of the serving RAT. The determining is based on whether a difference between a signal quality of a first frequency of the neighbor RAT and a signal quality of a second frequency of the neighbor RAT exceeds a threshold.

    Abstract translation: 当UE离开服务无线电接入技术（RAT）的覆盖区域并且进入相邻RAT的覆盖区域时，用户设备（UE）减少测量过程的等待时间。 在一个实例中，UE在由服务RAT的基站分配的测量间隙期间执行邻居RAT的相邻频率的RAT间测量。 在服务RAT的测量间隙期间，UE还确定是否切换用于解码同步信道的相邻RAT的频率。 该确定基于相邻RAT的第一频率的信号质量与相邻RAT的第二频率的信号质量之间的差异是否超过阈值。

    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 user equipment (UE) reduces redirection failure resulting from failed paging responses and/or location area updates when a user equipment is redirected from a first radio access technology (RAT) to a second RAT in accordance with a mobile terminated (MT) call. The UE is redirected from a first RAT to a second RAT in response to receiving a page for a call. The UE searches for neighbor cells of a first cell when a first paging response failed for the first cell in the second RAT. The UE also attempts to acquire a neighbor cell. The UE sends a second paging response, with a redirection indicator, to either the first cell or the neighbor cell based on a signal quality of the first cell and a signal quality of the neighbor cell when a failure of the first paging response to the first cell occurred within a predetermined time period.

    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.
