Abstract: Wireless communications systems and methods related to downlink performance of a UE in a wireless communication network are provided. For example, method of wireless communication performed by a user equipment (UE), the method comprising determining a level of interference to a reference signal received from a serving base station operating a first radio access technology (RAT) and switching, based on the determined level of interference, a radio access technology mode preference of the UE to a second RAT, the second RAT being different from the first RAT. Other features are also claimed and described.

Abstract: Aspects of present methods and apparatus relating to recovering from a HS-SCCH decode failure during wireless communication are disclosed. The described aspects include detecting that one or more packet data units (PDUs) are being transmitted on an uplink channel, wherein at least one of the one or more PDUs includes a POLL BIT set to TRUE. The described aspects further include determining that a time period for unsuccessful downlink scheduling satisfies a threshold; and. The described aspects further include triggering a cell update procedure with a cell update cause set to Radio Link Control (RLC) unrecoverable error (UNREC ERROR) based on the determination that the one or more PDUs are being transmitted on the uplink channel and that the time period for unsuccessful downlink scheduling satisfies the threshold.

Abstract: Methods, systems, apparatuses, and devices are described for transmitting a measurement report during wireless communications. When, for example, a low-power period (e.g., CDRX OFF period) is scheduled to begin during a time defined by a measurement event timer (TTT timer), a UE may modify the low-power period. The low-power period may be modified based, at least in part on determining the low-power period of the UE will begin during a time defined by a measurement event timer, a duration of the measurement event timer, and a duration of the low-power period. Modifying the low-power period may include delaying the start of the low-power state until after transmission of the MR associated with the measurement event timer or skipping the low-power period altogether. The UE may transmit the MR based, at least in part, on the modification.
