Some aspects of the disclosure relate to devices and methods for determining, at a user equipment, that a first condition is triggered for performing one or more layer 1 signal measurements for inter-cell mobility, performing the one or more L1 signal measurements of one or more cells in a configured cell set for the user equipment based on determining that the first condition is triggered, and sending a report of the one or more L1 signal measurements to a network node.

Abstract: Methods, systems, and devices for wireless communication are described related to timer-based sidelink discontinuous reception (DRX). A UE may receive configuration information for a sidelink DRX mode from a base station or another UE, which may indicate one or more parameters of the sidelink DRX mode. When operating in the sidelink DRX mode, a group of UEs may have shared active durations and inactive durations for coordinating sidelink communications. In a timer-based sidelink DRX mode, if a UE receives or transmits a sidelink communication, the UE may initiate an inactivity timer, and the UE may continue to monitor a sidelink channel for other sidelink communications while the timer is running. One or more rules may govern the operation of an inactivity timer with respect to the shared inactive durations.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify uplink (UL) control information (UCI) to transmit during a subframe. The UE may then select a UL channel on which to transmit the UCI based on whether a shared data and control UL channel employs contention-based scheduling. For example, multiple UEs could contend for access to the same semi-persistently scheduled (SPS) physical UL shared channel (PUSCH). Each UE may utilize a different demodulation reference (DMRS) signal cyclic shift to identify their transmissions. In some cases, some UCI, such as channel state information (CSI), may be transmitted on a contention-based PUSCH, while other UCI, such as acknowledgement information, may be transmitted on a physical uplink control channel (PUCCH). In some cases, the channel selection may be based on a configuration received from a base station.

Abstract: A method of handover at a user equipment (UE) is provided comprising receiving, from a first network entity (NE), a configuration for conditional handover associated with a second NE. The configuration includes at least one condition. An indication is received by the UE from the first NE to execute the conditional handover. Handover is initiated from the first NE to the second NE subject to the condition being satisfied. The condition may be that the indication is received or it may be a channel condition or both. At an NE, configurations for conditional handover are sent to multiple UEs, each configuration associated with a target NE and each including at least one condition, and an indication is sent to at least one UE to execute conditional handover.

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: Inform a master node about the feasible of secondary node cells during resumption of dual connectivity may require a large message. Additionally, the message may need to be encrypted. A solution to overcome the size and security limitation is to report a short identifier (or index) which is only shared between the UE and the MN. Accordingly, an apparatus, e.g., a UE, may be configured to receive, from a master node, a configuration comprising a mapping of cell identities for a plurality of secondary cells for reporting SN measurements and transmitting an SN report comprising measurements for at least a subset of the plurality of secondary cells using the mapping of cell identities. The apparatus may be configured to receive, from a first master node, a configuration for MN-DC, enter an inactive state or an idle state, and resume a connected state with a second master node.

In some aspects, a user equipment (UE) may perform early measurement report (EMR) measurements for a first set of carriers in an EMR time window. The UE may perform at least one verification operation for the EMR measurements based at least in part on at least one carrier measurement in a verification time window. The UE may transmit, to a network node, measurement results associated with the EMR measurements for one or more carriers in the first set of carriers based at least in part on the at least one verification operation. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a measurement configuration including trigger conditions for performance of handover procedures within a service-based wireless system. The UE may transmit a message indicating a satisfaction of a trigger condition to a source network entity, a mobility service offered by a service-based network, or both. After performance of a handover decision by the source network entity, the mobility service, or both, the mobility service may select a target network entity for the handover procedure. The mobility service may select a target network entity that supports at least one active core network service at the UE. The UE may then receive a handover command from the mobility service, and may perform a handover procedure to the target network entity.

A first user equipment (UE) may determine to perform a relay selection procedure and receive respective messages from one or more second UEs including one or more parameters for selecting a second UE to relay communications between the first UE and a network entity. The first UE may determine that respective parameters satisfy a threshold and select the second UE associated with the respective parameters. In some cases, the first UE may receive a control message prior to performing the relay selection procedure. The control message may include a configuration for modifying the communication path that includes an indication of one or more candidate UEs for relaying communications between the first UE and the network entity.

In other examples, the UE may monitor for a random access response (RAR) message from the first cell, the RAR message including an activation command that activates the first cell and an indication of a timing advance value generated based on the random access message. The UE may communicate with the first cell based on the activation command and the timing advance value.
