Abstract: Disclosed are techniques for enabling a user equipment (UE) operating in carrier aggregation mode to use different connected mode discontinuous reception (CDRX) configurations for different sets of component carriers associated with different sets of numerologies. For example, in Frequency 1 (FR1) plus Frequency 2 (FR2) carrier aggregation (i.e., one or more FR1 component carriers and one or more FR2 component carriers), a different CDRX can be configured for FR1 than for FR2. In inter-band carrier aggregation (i.e., one or more component carriers in one frequency band and one or more component carriers in another frequency band), CDRX can be configured per band. For mixed numerologies carrier aggregation (i.e., one or more component carriers with a first numerology and one or more component carriers with a different numerology), CDRX can be configured per cell group, where each cell group contains a single numerology or mixed numerologies.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, for a combination of a first band and a second band, whether a measurement offset is to be applied for a neighbor measurement on the second band based at least in part on an estimated impact of interference from the first band on the second band; and selectively apply the measurement offset for the neighbor measurement based at least in part on whether the measurement offset is to be applied; or selectively report the measurement offset to a base station associated with the neighbor measurement based at least in part on whether the measurement offset is to be applied. Numerous other aspects are provided.

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: Certain aspects of the present disclosure relate to methods and apparatus for improving voice over new radio (VoNR)-to-voice over long term evolution (VoLTE). An example method generally includes communicating with and camping on a next generation node B (gNB) in a 5G new radio (NR) system; initiating a voice call with the gNB; receiving a 5G NR-to-long term evolution (LTE) handover command in response to initiating the voice call; performing a handover procedure in response to the handover command; detecting a failure in the handover procedure; and taking one or more actions in response to detecting the failure in the handover procedure.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a grant delay request to a base station. The grant delay request may indicate a future time, at or thereafter a base station is requested to allocate resources to the UE. The base station may transmit the uplink grant to the UE allocating the resources to the UE based on the grant delay request, and the UE may transmit, to the base station, an uplink transmission including the uplink data based on the uplink grant. The UE may transmit the grant delay request as part of a scheduling request (SR), or as part of a buffer status report (BSR), or a combination of these.

Abstract: Enhanced inter-RAT and measurement gap operations are disclosed. In one aspect, a device may generate a customized measurement gap for monitoring control signals of another network for inter-RAT procedures. In another aspect, a device may modify, such as extend or shift, a network measurement gap to generate a modified measurement gap for monitoring control signals of another network for inter-RAT procedures. The device may modify the network measurement gap to align the network's measurement gap, such as LTE measurement gap, with a measurement window of another network, such as an SMTC window of a 5G network. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may be scheduled to perform a first measurement or paging activity associated with a target cell operating according to a first target cell configuration that is different from a serving cell operating according to a first serving cell configuration of the UE. In some cases, the UE may determine that the UE has performed a previous measurement or paging activity associated with the target cell while being served by the serving cell, the cells operating according to previous cell configurations. The UE may compare at least one of the first and previous target cell configurations or the first and previous serving cell configurations, and may perform the first measurement or paging activity using a script, where the script is either reused or rebuilt based on comparing the cell configurations.

Abstract: The present disclosure relates to a user equipment (UE) dynamically adjusting a non-access stratum (NAS) timer. Specifically, the UE may determine operation in a wideband and support of an extended coverage (EC) restriction. The UE may further identify a duration of a non-access stratum (NAS) timer based on determining operation in the wideband and the EC restriction. The UE may further transmit an access request message to a network entity to trigger a mobility management procedure. The UE may further receive an acceptance message from the network entity indicating an unrestricted or restricted status of the EC restriction. The UE may further apply the duration to the NAS timer based on the acceptance message indicating the unrestricted or restricted status of the EC restriction received from the network entity or a history of EC restrictions of a public land mobile network (PLMN) in a defined geographic area.

Abstract: Methods, systems, and devices for wireless communications are described. A method may include identifying an absence of a subscriber identity module (SIM) profile (e.g., in response to powering on a communication component). The method may further include determining a provider-specific configuration for communications with a wireless network and generating a set of SIM configuration parameters for a registration procedure with the wireless network based on identifying the absence of the SIM profile and the provider-specific configuration. The method may further include performing a registration procedure with the wireless network using the set of SIM configuration parameters.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques are described to enable wake-up signal (WUS) error handling at a user equipment (UE). The UE may detect an error pattern when attempting to receive a WUS from a base station based on a configuration for receiving the WUS. For example, the base station may transmit the configuration for receiving the WUS to a set of UEs including the UE. Based on detecting the error pattern, the UE may perform a mitigation operation based on determining the error pattern, such as waking up multiple cells to receive a transmission indicated by the WUS, transmitting a radio link failure indication to the base station, etc. Additionally or alternatively, the base station may transmit multiple WUSs to the UEs, such as a first WUS according to the configuration and a second WUS according to a reconfiguration.
