Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein provide timing advance validation for secondary cell (SCell) activation. Prior to receiving a SCell de-activation message associated with a SCell, a user equipment (UE) may determine a TA value for uplink transmissions to the SCell, and the UE may determine a first signal quality metric associated with wireless communication between the UE and the SCell. The UE may receive the SCell de-activation message, and, at a later time, may receive a SCell activation message. The UE may determine whether the TA value determined prior to receipt of the SCell de-activation message is valid for the wireless communications between the UE and the SCell based on a difference between the first signal quality metric and a second signal quality metric determined after receipt of the SCell activation message.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may transmit, to a user equipment (UE), a configuration including a parameter indicating a quantity of scheduled measurement gaps that may be used for performing measurements. The UE may apply the parameter by suppressing one or more measurement gaps and may receive data from the network entity via one or more time resources (e.g., a slot, a symbol) associated with the suppressed measurement gaps. The UE may perform measurements during the measurement gaps that are not dropped. In some examples, the network entity may configure the parameter based on scheduled data traffic, one or more criteria associated with the UE satisfying a threshold, or any combination thereof. In some examples, the UE may stop applying the parameter based on a timer, an event trigger, or both.

Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE receives, from a network entity, a channel state information (CSI) report configuration including a set of sub-configurations. Each sub-configuration in the set of sub-configurations corresponds to a transmission setting associated with a channel state information reference signal (CSI-RS). The UE further determines one or more CSIs respectively corresponding to a subset of the set of sub-configurations, and transmits, based on the transmission setting corresponding a first sub-configuration of the subset of sub-configurations, a reduced content of a CSI report or refrains from transmitting the CSI report. The CSI report is associated with a first CSI for the first sub-configuration.

Abstract: Apparatuses and methods for altitude-dependent measurement and reporting configurations are described. An apparatus is configured to receive, from a network node, a measurement object configuration, where the measurement object configuration indicates at least one altitude parameter associated with a set of SSBs. The apparatus is also configured to measure a SSB value for each SSB in the set of SSBs based on the measurement object configuration and an altitude of the UE. An additional apparatus is configured to configure, for a UE, a measurement object configuration, where the measurement object configuration indicates at least one altitude parameter associated with a set of SSBs. The additional apparatus is also configured to provide the set of SSBs indicated in the measurement object configuration.

Abstract: Certain aspects of the present disclosure provide techniques for improving a network energy saving (NES) mode. An example method performed by a first user equipment (UE) includes receiving, from a first network entity associated with a source cell, configuration information indicating one or more conditions for executing a conditional handover from the first network entity associated with the source cell to a second network entity associated with a target cell, receiving, from the first network entity associated with the source cell, a trigger signal including a trigger command for the conditional handover, and taking one or more actions related to executing the conditional handover based on the trigger signal and the one or more conditions.

Abstract: A user equipment (UE) receives one or more timing advance commands from a non-terrestrial network (NTN). The UE resets, after a GNSS fix, a cumulative timing advance value based on the one or more timing advance commands from the NTN and transmits an uplink transmission with a timing advance based on a self-estimated delay and the cumulative timing advance value. The UE may adjust a self-estimated delay based on at least one GNSS fix. The UE may transmit an uplink transmission with a timing advance based on the adjusted self-estimated delay and a cumulative timing advance value based on the one or more timing advance commands from the NTN.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a synchronization signal/physical broadcast channel (SS/PBCH) block index, associated with an SS/PBCH block, based at least in part on a set of bits included in a payload of a PBCH of the SS/PBCH block, a demodulation reference signal (DMRS) sequence included in the PBCH, a scrambling sequence associated with the PBCH, or an interleaving associated with the PBCH. Numerous other aspects are described.

Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE monitors a serving cell through one or more active transmission configuration indication (TCI) states of the serving cell, and monitors a reference signal associated with one or more partially active TCI states of a non-serving cell for lower-layer triggered mobility (LTM). The UE further performs the LTM handover to change the serving cell in response to an LTM command and based on at least one of the partially active TCI states and the active TCI states. The method enables the UE to use a partially active TCI state to monitor a reference signal of candidate cells for LTM. It substantially reduces the LTM HO delay and interruption length during an LTM HO. Hence, it improves the efficiency of wireless communication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate, before establishing a radio resource control (RRC) connection, support for demodulation reference signal (DMRS) bundling of a message of a random access (RA) procedure. The UE may transmit the message of the RA procedure based at least in part on the support for DMRS bundling. Numerous other aspects are described.
