Abstract: Aspects of the disclosure provide an electronic device including processing circuitry and a method for beam management (BM) with power saving. The processing circuitry can receive a reference signal from a network via a serving beam pair used for downlink (DL) transmission between the network and an electronic device. The serving beam pair can include a serving transmission (Tx) beam transmitted from the network and a serving reception (Rx) beam received by the electronic device. The processing circuitry can determine a signal quality of the reference signal. When the signal quality is determined to satisfy a power saving condition, the processing circuitry can reduce beam measurements in the BM for beam pairs including Tx beams transmitted from the network and respective Rx beams received by the electronic device. The beam pairs can include the serving beam pair and one or more candidate beam pairs.

Abstract: In one aspect, a User Equipment (UE) performs Radio Resource Management (RRM) measurements on downlink signals with a first cycle period equal to the UE's Discontinuous Reception (DRX) cycle period. The RRM measurements cycle period is lengthened when UE detects that a signal quality measurement of the primary cell is greater than the sum of a positive offset and a signal quality measurement of a neighboring cell having the best signal quality among all of UE's neighboring cells. In another aspect, a UE de-multiplexes a paging indication which precedes a Synchronization Signal Block (SSB) in time and is generated using the same sequence generation formula as that for generating a Secondary Synchronization Signal (SSS) in the SSB. From the de-multiplexed paging indication, the UE detects that it is paged for message reception and wakes up to receive the message in a next data reception period of the UE's DRX cycle.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE attempts to detect a trigger event. The UE determines values of a first set of power configuration parameters when the trigger event is detected, wherein a change in a value of each power configuration parameter in the first set of power configuration parameters affects power consumption of the first UE. The UE transmits or receives signals in accordance with the values of the first set of power configuration parameters.

Abstract: Apparatus and methods for unknown physical uplink control channel (PUCCH) secondary cell (SCell) activation are proposed. The network node may transmit a PUCCH SCell activation command for an unknown target PUCCH SCell to the UE. After receiving the PUCCH SCell activation command for the unknown target PUCCH SCell, the UE may transmit a layer 1 (L1) report or a layer 3 (L3) report for the unknown target PUCCH SCell to the network node before the unknown target PUCCH SCell is activated. The network node may obtain measurement information based on the L1 report or the L3 report before the unknown target PUCCH SCell is activated. Then, the network node may perform corresponding operations based on the L1 report or the L3 report before the unknown target PUCCH SCell is activated.

Abstract: A method for enhancing Bandwidth Part (BWP) operation towards Secondary Cell (SCell) dormancy indication is proposed. A User Equipment (UE) detects a Downlink Control Information (DCI) format including an SCell dormancy indication that indicates an active BWP change for a serving cell. The UE performs BWP switching for the serving cell in response to the DCI format. The UE stops transmission or reception in the serving cell during a time duration from a slot containing a last symbol of the DCI format, wherein the time duration includes a first period of time of delay for the BWP switching and a second period of time of interruption to other active serving cells.
