Mobility enhancements and power saving for user equipment communication

An apparatus for wireless communication at a user equipment (UE), comprising:

• a memory;
• and
• at least one processor coupled to the memory and, based at least in part on information stored in the memory, the at least one processor is configured to:
• perform a measurement of at least one of a source node or a target node;
• and
• transmit UE assistance information (UAI) associated with power saving,
• coverage enhancement, reliability enhancement, measurements, sensing, channel sounding, a dedicated physical random access channel (PRACH) resource, and preferred configurations for a beam, a transmission reception point (TRP), or a cell in the target node based on a condition associated with at least one of a first measurement of the source node being below a first signal quality threshold or a second measurement of the target node being above a second signal quality threshold.

An apparatus for wireless communication at a source node, comprising:

• a memory;
• and
• at least one processor coupled to the memory and, based at least in part on information stored in the memory, the at least one processor is configured to:
• configure, for a user equipment (UE), a first configuration for an active downlink (DL) bandwidth part (BWP) at the UE, a second configuration for a default DL BWP at the UE, a BWP inactivity timer, and a mobility reception timer;
• and
• receive, from the UE, a measurement of at least one of the source node or a target node, wherein the measurement corresponds to the UE operating on the active DL BWP in the source node;
• wherein the BWP inactivity timer and the mobility reception timer are configured with a triggering condition associated with the measurement.

An apparatus for wireless communication at a source node, comprising:

• a memory;
• and
• at least one processor coupled to the memory and, based at least in part on information stored in the memory, the at least one processor is configured to:
• configure, for a user equipment (UE), a configuration to provide UE assistance information (UAI) associated with power saving, coverage enhancement, reliability enhancement, measurements, sensing, channel sounding, request for dedicated physical random access channel (PRACH) resource, and preferred configurations for a beam, a transmission reception point (TRP), or a cell in a target node based on a condition associated with at least one of a first measurement of the source node being below a first signal quality threshold or a second measurement of the target node being above a second signal quality threshold;
• and
• receive, from the UE, the UAI based on the configuration.
