Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform a first scan procedure for a first of radio frequency bands according to a default scanning order at a first subscription of the UE, store an indication of a subset of radio frequency bands of the first set of radio frequency bands for the first scan procedure, and perform a second scan procedure for a second set of radio frequency bands according to a modified scanning order based on the stored indication of the subset of radio frequency bands. In some cases, the UE may determine a relevance of the stored indication of the subset of radio frequency bands of the first set of radio frequency bands and determine the modified scanning order based on the relevance of the stored indication.

Abstract: A method of wireless communication at a user equipment (UE), including: generating a first set of frequencies to search for signals from at least one candidate cell from which the UE may receive wireless service with respect to a first subscriber identity module (SIM); generating a second set of frequencies to search for signals from the at least one candidate cell from which the UE may receive wireless service with respect to the first SIM; scanning for one or more signals from the at least one candidate cell including tuning a first transceiver configured to operate in accordance with the first SIM to one or more of the first set frequencies; and scanning for one or more signals from the at least one candidate cell including tuning a second transceiver configured to operate in accordance with a second SIM to one or more of the second set of frequencies.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a user equipment (UE), generally including receiving, from a network entity, information regarding candidate cells configured for conditional handover (CHO), determining, based on the information regarding the candidate cells, an order to scan frequencies for an acquisition database based scan, and performing the acquisition database based scan in the determined order.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine at least one of: the UE is not camped on a millimeter wave (mmW) cell and no neighboring cells are mmW cells, or the UE is operating in a mobility state. The UE may forgo, based on the determination, a manual public land mobile network (MPLMN) scan of mmW frequency bands. The UE may perform, based on the determination, an MPLMN scan of only non-mmW frequency bands for non-mmW cells. Numerous other aspects are described.
