Abstract: A method of wireless communication receives a frequency list for fast return when in idle mode in a first radio access technology (RAT). The method updates the frequency list for fast return to the first RAT while in connected mode in the first RAT. The update is based on inter and intra frequency measurement control messages from each serving base station during mobility.

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 skip performance of base station identity code (BSIC) confirm and reconfirm procedure for a neighbor cell to conserve UE battery power. In such instances, the UE compares a serving cell signal metric to a dynamic threshold. The BSIC confirm and reconfirm procedure for the neighbor cell may be skipped when the serving cell signal metric is above the dynamic threshold.

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: When a user terminal is communicating with asynchronous systems, it may calculate the propagation delay of received signals using the frame offset from the asynchronous base stations. The user terminal may calculate a time difference between a frame reference of a first base station and a second base station and use the time difference to determine a propagation time difference.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive from a base station a measurement configuration signal comprising a measurement resource configuration associated with a cross-link interference signal strength measurement. The UE may perform the cross-link interference signal strength measurement for one or more UEs associated with one or more intra-frequency neighboring cells according to the measurement resource configuration, wherein the cross-link interference signal strength measurement is performed during an intra-frequency measurement gap. The UE may transmit a report of the cross-link interference signal strength measurement to the base station.

Abstract: Methods, systems, and devices are described for concurrently performing handoff-related measurements for neighbor cells using multiple input multiple output (MIMO) antenna resources. In one example, a mobile device is in communication with a serving cell. Handoff-related measurements of first wireless signals from a first neighbor cell are performed. The first wireless signals are received at first MIMO antenna resources of a device. Handoff-related measurements of second wireless signals from a second neighbor cell are performed, as well. The second wireless signals are received at second MIMO antenna resources concurrently with the first wireless signals received at the first MIMO antenna resources. The first handoff-related measurements and the second handoff-related measurements may be performed during a scan interval. A type of handoff-related measurement to perform may be determined based on a determined length of the scan interval.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may coordinate and improve data flows between wireless communication networks based on messaging between a modem processor and an application processor. In a first example, the modem processor may control the splitting of traffic between a first wireless communication network (e.g., a cellular network) and a second wireless communication network (e.g., a Wi-Fi network). The modem processor may establish a multiple access session (e.g., a multiple access protocol data unit session) that includes a session for each wireless communication network, and route traffic (e.g., communications with a network entity) based on access traffic steering, switching, and splitting (ATSSS) rules. In a second example, the application processor may control the traffic splitting. The application processor may obtain the ATSSS rules from the modem processor, and route traffic accordingly.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for limiting handoffs in cellular networks. In some aspects, a user equipment (UE) may determine a quantity of handoffs that are performed between two or more radio access technologies (RATs) during a time period. The UE may determine whether the quantity of handoffs exceeds a handoff threshold within the time period. The UE may reduce a rate of handoffs when the UE determines that the quantity of handoffs exceeds the handoff threshold within the time period. The UE also may select one of the RATs to camp on and maintain the wireless connection when the UE determines that the quantity of handoffs exceeds the handoff threshold. The UE may determine which RAT to camp on based on handoff count information, handoff total connection time information, or contextual awareness information.

Abstract: Various embodiments include methods for autonomous beam switching by a wireless device. A processor of the wireless device may measure signal parameters of signals received from a first synchronization signal block (SSB) beam of a base station monitored by the wireless device and other SSB beams of the base station, determine whether a difference in measured signal parameters of signals received from the first SSB beam and another SSB beam of the base station satisfies a signal quality difference threshold, and autonomously switching to the second SSB beam as the serving beam in response to determining that the difference in the measured signal parameters of signals received from the first SSB beam and a second SSB beam satisfies the signal quality difference threshold. The signal quality difference threshold may be listed in a table in memory or determined via machine learning.
