Abstract: A method of wireless communication, by a user equipment (UE), includes scanning a wireless network for a system information message containing inter-radio access technology (IRAT) frequency information for a non-terrestrial network. The method also includes displaying a non-terrestrial network icon on a user interface of the UE in response to receiving the system information message. The icon indicates non-terrestrial network coverage.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information identifying a set of cells configured for conditional handover (CHO). The UE may identify one or more features associated with a cell. The UE may monitor one or more cells of the set of cells, wherein the one or more cells are associated with the one or more features, and wherein the one or more cells are prioritized over cells not associated with the one or more features in the cell search. The UE may initiate a handover to an identified cell based at least in part on the cell search. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive handover information associated with one or more neighbor cells. The UE may identify that a first discontinuous reception (DRX) cycle associated with a first subscriber identity module (SIM) of the UE at least partially overlaps with a second DRX cycle associated with a second SIM of the UE. The UE may identify that at least one of the first DRX cycle or the second DRX cycle does not overlap with a third DRX cycle associated with a neighbor cell of the one or more neighbor cells. The UE may transmit, to the neighbor cell, a message associated with a handover of at least one of the first SIM or the second SIM to the neighbor cell. Numerous other aspects are described.

Abstract: Techniques for recovering quickly from a radio link failure (RLF) by identifying potentially strong candidate cells, while avoiding the conventional delays from relying only on initial ACQ DB scans followed by band-scanning, are disclosed. In one aspect, a wireless apparatus such as a user equipment (UE) may identify a radio link failure (RLF) of an existing wireless connection. The UE may prioritize, during an RLF recovery procedure for restoring the connection, candidate cells using connection criteria from one or more measurement reports. The UE can thereupon restore the connection using a cell having a highest priority. In various configurations, the UE can use cells from A3, A4, A5, inter-RAT or periodic measurement reports to reestablish a stronger connection in a faster time.

Abstract: Certain aspects of the present disclosure provide a method of wireless communications at a user equipment (UE), generally including detecting, within a period, a number of indications for modification to system information from a cell and performing one or more actions, after the detection, to prevent the UE from attempting to access the cell.

Abstract: Methods and mechanisms for performing idle mode mobility procedures are provided. According to one aspect of the present disclosure, a method for wireless communication performed by a user equipment (UE) includes: receiving, from a base station (BS) on a first cell, system information indicating a first cell reselection priority configuration; receiving, from the BS, dedicated signaling indicating a dedicated cell reselection priority configuration, wherein the dedicated cell reselection priority configuration is empty; and connecting, while in an idle mode and in response to the dedicated cell reselection priority configuration being empty, to a second cell different from the first cell based on the first cell reselection priority configuration received in the system information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a first service associated with a first subscriber identification module (SIM), the first service having a first priority. The UE may identify at least one re-prioritization condition that is satisfied, wherein the at least one re-prioritization condition is associated with at least one of the first service or a second service associated with a second SIM, the second service having a second priority that is lower than the first priority. The UE may adjust, based at least in part on the at least one re-prioritization condition being satisfied, the second priority, wherein the adjusted second priority is higher than the first priority. The UE may perform a communication corresponding to the second service based at least in part on the adjusted second priority. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, at a packet data convergence protocol (PDCP) layer, a packet having a PDCP sequence number. The UE may determine whether the received packet, having the PDCP sequence number, satisfies one or more reordering criteria. The UE may discard, before an expiration of a reordering timer, the received packet based at least in part on the determination of whether the received packet satisfies the one or more reordering criteria. Numerous other aspects are provided.

Abstract: Aspects relate to techniques for expediting New Radio (NR) cell addition in non-standalone (NSA) mode. The UE may receive a conditional handover (CHO) command from a first anchor cell operating a first frequency range (e.g., a Long Term Evolution (LTE) frequency range) that enables the UE to subsequently select a different anchor cell to which to perform a handover. The UE may then receive a deconfiguration from the first anchor cell of a measurement object for secondary cell addition in a second frequency range (e.g., a NR frequency range). Based on the CHO command and the deconfiguration of the measurement object, the UE may then perform a handover to a second anchor cell in the first frequency range to facilitate addition of at least one secondary cell in the second frequency range.
