Abstract: A method and apparatus for wireless communication stores synchronization channel (SCH) timing for each identified Global System for Mobile Communications (GSM) cell. The stored SCH timing is used to perform base station identity code (BSIC) reconfirmation for an identified GSM cell without frequency correction channel (FCCH) tone detection and initial BSIC confirmation. The stored SCH timing is maintained across a plurality of user equipment (UE) states.

Abstract: An early BSIC (base station identity code) abort procedure includes comparing a first signal strength of a serving cell with a first threshold and comparing a second signal strength of a target cell to a second threshold. The first threshold is a sum of a network indicated threshold and a user equipment (UE) threshold. The second threshold is a difference between the network indicated threshold and the UE threshold. When the first signal strength is below the first threshold and the second signal strength is above the second threshold, the base station identity code (BSIC) procedure is initiated. A number of BSIC failure attempts is adaptively set before terminating the BSIC procedure.

Abstract: A method of wireless communication enables an inter-radio access technology (IRAT) neighbor cell measurement when a serving RAT signal strength is continuously below a first threshold value for a first length of time. The method also disables the IRAT neighbor cell measurement when the serving RAT signal strength is continuously above a second threshold value for a second length of time.

Abstract: A user equipment (UE) may perform an inter radio access technology (IRAT) measurement in time slots not deemed to be carrying critical data. In such instances, the UE only transmits and decodes critical data in the critical time slots when a serving cell signal is low for a determined period of time. Otherwise, when the time slots do not carry critical data, i.e., non-critical time slots, the UE stops transmitting and decoding and uses the non-critical time slots for IRAT measurement.

Abstract translation: 用户设备（UE）可以在不被认为携带关键数据的时隙中执行互无线接入技术（IRAT）测量。 在这种情况下，当服务小区信号在确定的时间段内为低时，UE仅在关键时隙中发送和解码关键数据。 否则，当时隙不携带关键数据，即非关键时隙时，UE停止发送和解码，并将非关键时隙用于IRAT测量。

Abstract: A user equipment (UE) may reduce reselection delays when the UE is in the idle mode. In such instances, the UE adaptively adjusts a cell reselection timer based at least in part on the availability of a downlink time slot resource. The adjustment of the cell reselection timer may be based at least in part on the availability of the downlink time slot resources. The cell reselection timer is adjusted (e.g., shortened or scaled down) when the downlink time slot resources are unavailable to the UE.

Abstract translation: 当UE处于空闲模式时，用户设备（UE）可以减少重选延迟。 在这种情况下，UE至少部分地基于下行链路时隙资源的可用性自适应地调整小区重选定时器。 小区重选定时器的调整可以至少部分地基于下行链路时隙资源的可用性。 当下行链路时隙资源对UE不可用时，小区重选定时器被调整（例如缩短或缩小）。

Abstract: A user equipment (UE) configured for dual connectivity with a split bearer configuration may transmit uplink data packets to one or both a master cell group (MCG) and a secondary cell group (SCG). The UE may transmit an uplink transmission from a packet data convergence protocol (PDCP) entity over one or both of a first radio link control (RLC) entity associated with the MCG and a second RLC entity associated with the SCG. The configuration including a transmit buffer threshold. The UE may receive, at the PDCP entity, an uplink switch start indication. The UE may activate the second RLC entity in response to receiving the uplink switch start indication. The UE may transmit a buffer status report according to a current transmit buffer level plus the transmit buffer threshold. Accordingly, the UE may communicate with the SCG based on the uplink switch start indication.

Abstract: A user equipment (UE) may use multiple subscriber identification modules (SIMs) in dual-SIM dual-active (DSDA) communications. The A DSDA UE may support identification of a set of available radio frequency (RF) resources for communications, where the set of available RF resources include multiple RF components (e.g., transmit/receive antennas), RF baseband resources (e.g., processing resources that support processing and decoding of transmissions), or combinations thereof. The set of available resources may be shared between multiple SIMS, and the UE may identify different resource partitions of the set of available resources, with different resource partitions used to provide concurrent communications of both the first SIM and the second SIM based on parameters of each SIM.

Abstract: Methods, systems, and devices for wireless communications are described for low noise amplifier (LNA) configurations of a user equipment (UE) operating in a dual-subscriber dual-active (DSDA) mode. The UE may establish first and second communications links via two or more antenna ports using a first subscriber identity module (SIM) and a second SIM in the DSDA mode. The UE may identify a LNA configuration from two or more available LNA configurations for receiving at least partially concurrent communications of the first SIM and the second SIM based at least in part on activation of the DSDA mode and a difference between a first received signal strength associated with the first SIM and a second received signal strength associated with the second SIM. The UE may receive the at least partially concurrent communications via the two or more antenna ports based at least in part on the identified LNA configuration.

Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE starts a first timer (such as a discontinuous reception (DRX) hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer), after sending an uplink (UL) data transmission to a network entity. The UE then starts a second timer (such as a DRX retransmission timer) when the first timer expires. The UE then determines whether to wake up or sleep for a duration of the second timer based on a prior block error rate (BLER).
