Abstract: A delta configuration is signaled for handover of a wireless communication device (e.g., a user equipment, UE) from a first form of connectivity to a second form of connectivity. For example, a UE with master cell group (MCG) connectivity may be handed-over to multiple radio access technology-dual connectivity (MR-DC). In some examples, a UE with standalone (SA) connectivity may be handed-over to non-standalone (NSA) connectivity (e.g., dual connectivity). In conjunction with this handover the UE may be signaled as to whether the UE is to reuse a configuration from the first connectivity mode during the second connectivity mode.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling for communications in a wireless communications system. The control signaling may indicate a first duration for an inactivity timer. The UE may initiate the inactivity timer and a second timer based on identifying a period of inactivity. The second timer may have a second duration that is shorter than the first duration for the inactivity timer. In some examples, the second duration may be based on one or more parameters, such as a display status, a battery status, a scaling factor, the first duration, an application state, or any combination thereof. The UE may release a connection for the communications in the wireless communications system based on an expiration of the second timer, an expiration of the inactivity timer, or a combination thereof.

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: 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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured with two subscriptions. The first subscription may support dual connectivity with one or more cell groups, such as a master cell group (MCG) and a secondary cell group (SCG), while a second subscription may not support dual connectivity. Each subscription may support communications with one or more radio access technologies (RAT). The UE may use the protocol stack for a RAT in the first subscription to receive idle-mode signaling, such as one or more paging messages, from the second subscription using the same RAT.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, a UE capability message associated with a number of downlink multiple-input and multiple-output (MIMO) layers supported at the UE. The UE may receive a configuration for a set of downlink MIMO layers including a first subset of downlink MIMO layers configured for a first cell and a second subset of downlink MIMO layers configured for a second cell. The UE may allocate a first set of resources to the first cell or the second cell, or both, based on the first and the second subset of downlink MIMO layers. The UE may determine a second set of resources are unallocated to the set of downlink MIMO layers and allocate the second set of resources to the first cell or the second cell, or both.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate via a first connection using one or more transmit parameters. The UE may determine to suspend subsequent attempts to communicate via a second connection, in a dual connection mode, based at least in part on satisfaction of a threshold number of failed attempts to communicate via the second connection. The UE may determine one or more parameters for suspension of the subsequent attempts to communicate via the second connection based at least in part on a determination that satisfaction of the threshold number of failed attempts is associated with one or more exposure conditions that are based at least in part on the one or more transmit parameters. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A system may support techniques for triggering user equipment (UE) assistance information (UAI) based on mobility, wake up signal (WUS) configuration, or both. In some cases, a UE may communicate with a network node (e.g., a base station) on a first channel according to a discontinuous reception (DRX) configuration. The UE may determine that a speed of the UE satisfies a mobility threshold and may transmit UAI requesting one or more updated DRX configuration parameters based on the speed of the UE satisfying the mobility threshold. Additionally or alternatively, the UE may receive signaling configuring the UE to monitor for WUSs and may transmit UAI requesting one or more updated DRX configuration parameters based on the WUS configuration. The UE may receive control signaling configuring the DRX configuration with the one or more requested parameters in response to the UAI.

Abstract: Certain aspects of the present disclosure provide techniques for detecting power consumption conditions to trigger transmission of user equipment (UE) assistance information (UAI) for a reconfiguration request. For example, an example method by a UE generally includes detecting one or more conditions associated with at least one metric related to UE power consumption; and transmitting UAI to a network entity, in response to the detection, to request a reconfiguration of the UE to operate according to a set of one or more parameters selected based on a value of the at least one metric.

Abstract: A user equipment (UE) may be in a standalone (SA) mode and start a timer associated with barring a first cell, based on a system information block type 1 (SIB 1) decode timeout failure. The UE may receive, from a base station, a first redirection instruction to connect to the first cell in a non-standalone (NSA) mode. The UE in the NSA mode may determine that the measurement for the first cell is greater than a threshold value, and receive, from the base station a second redirection instruction to switch to the SA mode on the first cell. The UE may pause the timer and perform an initial acquisition procedure on the first cell.

Abstract: Aspects relate to a UE adapting the capability it advertises based on the network within which the UE is operating. In some examples, if a network currently supports a certain bandwidth, the UE may select the capabilities it will advertise based on that supported bandwidth. In some examples, a UE may acquire information regarding which configurations were considered by a network. In this case, the UE may select the capabilities it will advertise based on such configurations.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to maintain multiple message buffers for storing public warning system (PWS) information. The UE may receive a first segment of public PWS information via a first cell, where the PWS information is associated with a geographical scope that includes the first cell. The UE may perform a cell change procedure from the first cell to a second cell different from the first cell, and may receive a second segment of the PWS information via the second cell. The UE may then store the first segment and the second segment within multiple message buffers based on the second cell being included within the geographical scope associated with the PWS information.
