Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may compare an external list of ping pong handovers or redirections that is maintained by an access point, and an internal list of ping pong handovers or redirections that is maintained by the UE. The UE may identify a ping pong detection criterion, for a handover or redirection between a first network node and a second network node, based, at least in part, on the external list, the internal list, both the external list and the internal list, or neither of the external list nor the internal list indicating a previous ping pong handover or redirection between the first network node and the second network node. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently performing measurements and other functions in preparation for communicating with a base station on a secondary cell (SCell). In particular, a user equipment (UE) may switch to a certain bandwidth part (BWP) (e.g., a dormant BWP) on an SCell when the SCell is deactivated, and the UE may perform the appropriate measurements and functions on this BWP (e.g., based on reference signals received on this BWP). In some cases, the UE may determine to switch to the BWP for performing the appropriate measurements and functions based on an inactivity timer expiring or based on an indication from a base station (e.g., on a primary cell (PCell)). Accordingly, once the UE activates the SCell for communications with a base station, the latency associated with preparing for communicating on the SCell may be reduced.

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may divide a measurement of a cell into two or more portions. The UE may receive a control message that indicates a request to perform the measurement and a target frequency associated with the measurement. In some examples, the UE may generate at least a first radio frequency (RF) script during an on duration of a discontinuous reception (DRX) cycle based on the target frequency. The UE may perform at least a portion of the measurement during an off duration of the DRX cycle based on the first RF script. Additionally or alternatively, the UE may generate the first RF script and perform the portion of the measurement during an off duration of a DRX cycle and the UE may generate a second RF script during an off duration of a second DRX cycle.

Abstract: Techniques are provided for receiving encrypted positioning assistance data, requesting and obtaining cipher keys to decrypt the positioning assistance data. An example method for transmitting a cipher key request includes receiving cipher key information including a start time value, a duration value, and an advance time value, determining an advance time duration that is equal to a sum of the start time value and the duration value minus the advance time value, and transmitting the cipher key request within the advance time duration.

Abstract: Techniques for wireless communication at a communication device are described. The communication device may be a user equipment (UE) configured to transmit, to a base station, signaling indicating UE capability information. The UE may receive, from the base station, control signaling indicating a measurement gap sequence configuration based on the UE capability information. The UE may determine a measurement gap occasion based on the measurement gap sequence configuration. The measurement gap occasion may include one or more of a first measurement gap occasion associated with a first measurement gap sequence, a second measurement gap occasion associated with a second measurement gap sequence, or a combination of the first measurement gap occasion and the second measurement gap occasion. The UE may perform a set of channel measurements during the determined measurement gap occasion.

Abstract: Certain aspects of the present disclosure provide techniques for handling collisions between multiple universal subscriber identity module (MUSIM) gaps and measurement gaps (MGs) or other MUSIM gaps. In an exemplary method, a user equipment (UE) detects a collision between a first multiple universal subscriber identity module (MUSIM) gap occasion and at least one of a second MUSIM gap occasion or a measurement gap (MG) occasion; and processes signals in at least one of the first MUSIM gap occasion, the second MUSIM gap occasion, a third MUSIM gap occasion, or the MG occasion based on relative priorities of the first MUSIM gap occasion, the second MUSIM gap occasion, or the MG occasion.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that a cell is associated with a deployment mode based on a condition being satisfied, where the deployment mode may be associated with serving one or more UEs travelling at high speeds. The UE may select from one of a frequency-based initial cell selection or a cell-based initial cell selection and may measure one or more frequencies of one or more cells including the cell to obtain a set of measured parameters, each cell corresponding to a respective deployment mode and a respective measured parameter. The UE may select a candidate cell from the one or more cells based on the respective measured parameters of each cell and the respective deployment modes of each cell and may establish a connection with the candidate cell based on the selecting.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate a broadcast or multicast (broadcast/multicast) application associated with a first radio access technology (RAT) while the UE is in a standalone mode for a second RAT; switch from the second RAT to the first RAT based at least in part on initiating the broadcast/multicast application; and switch from the first RAT to the second RAT based at least in part on failing to detect a communication associated with the broadcast/multicast application using the first RAT. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station associated with a first radio access technology (RAT), a neighbor cell list including entries for at least a first set of neighbor cells and a second set of neighbor cells, the first set of neighbor cells and the second set of neighbor cells associated with a second RAT. The UE may determine that the first set of neighbor cells is associated with a first network operator and that the second set of neighbor cells is associated with a second network operator. The UE may measure at least one neighbor cell of the neighbor cell list based at least in part on prioritization of the first set of neighbor cells relative to the second set of neighbor cells. 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 detect, while operating in an out-of-service (OOS) mode associated with a first network, that a second network satisfies one or more switching criteria. The UE may increase a time duration associated with a periodic network acquisition scan associated with the first network based at least in part on detecting that the second network satisfies the one or more switching criteria. The UE may switch, while operating in the OOS mode, from using the first network for connectivity to using the second network for connectivity based at least in part on detecting that the second network satisfies the one or more switching criteria. Numerous other aspects are described.
