Abstract: A user equipment (UE) determines a tune-away gap in which the UE performs a tune-away from a first radio access technology (RAT) to a second RAT on a single radio frequency (RF) chain, and transmits an intended-false buffer status report (BSR) to modify a duration of the determined tune-away gap. The intended-false BSR indicates an intended-false value of uplink data pending in a buffer to be transmitted on the first RAT, so that an uplink grant for uplink data transmissions on the first RAT to be received at the UE is modified.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station according to a first radio access technology (RAT) in a first frequency range. The UE may perform measurements on a set of candidate cells of a second RAT or a second frequency range based on a determination for the UE to operate according to the second RAT or the second frequency range. The UE may perform a mobility procedure to establish a connection with a first cell of the set of candidate cells based on a determination that a first value of a first measurement parameter for the first cell satisfies a first threshold, and further based on a comparison of a different, second value of a second measurement parameter for the first cell to a second threshold.
