Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) detects a collision between a duration in time domain configured to receive downlink data for a dedicated data subscription (DDS) subscription of the MSIM UE and a first paging occasion configured to receive a paging message for a non-DDS (n-DDS) subscription of the MSIM UE. The UE may then monitor a second paging occasion different from the first paging occasion for the paging message, the second paging occasion configured to avoid collision with the duration in time domain.

Abstract: Methods, systems, and devices for wireless communications are described. In some aspects, a user equipment (UE) may be configured with multiple bandwidth parts (BWPs) and may support multiple subscriber identification modules (SIMs) (e.g., may operate in a multi-SIM (MSIM) mode). The UE may tune away from a default data SIM (DDS) subscription for a tune away gap and may miss any downlink signaling, such as an indication of a BWP switch, for a duration of the tune away. To avoid latency resulting from such missed downlink signaling, the UE may support a mechanism according to which the UE may autonomously switch to a different BWP despite a missed command from a network entity. Such a mechanism may include transmission of a scheduling request (SR) on each of multiple BWPs configured for the UE and monitoring each of the multiple BWPs for signaling responsive to the SR.
