Abstract: Techniques discussed herein may better ensure efficient fine time tracking during a second cell (SCell) activation procedure by using a tracking reference signal (TRS) that is User Equipment (UE) specific. A primary cell (PCell) may provide a UE with a TRS configuration that includes a UE-specific reference signal (RS) with periodicity or aperiodicity. In response to receiving a SCell activation command from the PCell, the UE may perform cell activation with fine time tracking in accordance with the UE-specific RS. As the delay time for the UE-specific RS may be less than the delay time for a system synchronization block (SSB) from the SCell, use of the UE-specific RS may expedite the cell activation procedure.

Abstract: The present disclosure relates to devices, apparatuses, and methods for enhanced PHR reporting in support of UE antenna scaling. A wireless device, which comprises at least one antenna array each comprising a plurality of antenna elements may perform antenna scaling by activating or deactivating at least one of the plurality of antenna elements (with corresponding RF chains) of one or more antenna arrays. The wireless device may generate a power headroom (PHR) report based at least on a difference between beamforming gains obtained after the antenna scaling and before the antenna scaling. The wireless device may then send the PHR report to a base station in communication with the wireless device.

Abstract: The present disclosure relates to measurement gap cancellation. A method for a user equipment (UE) may comprise receiving, from a network (NW) device, measurement gap (MG) cancellation information associated with a particular MG of one or more MG patterns to be used by the UE; and determining whether the particular MO shall be cancelled based on the MG cancellation information.

Abstract: A terminal may communicate through a first communication link with a first network. The terminal may include a transmitter that transmits, to a second network, a terminal capability indicating support for a measurement configuration. The terminal may include a receiver that receives, from the second network, network configuration information including a pattern for establishing a second communication link with the second network. The terminal may include a processor that, based on the pattern, establishes the second communication link with the second network while maintaining the first communication link with the first network. The network configuration information may be based on an independent frequency range (FR) measurement included in the terminal capability.

Abstract: Systems and methods for analyzing a validity of an early measurement report (EMR) measurement result are described herein. A base station may configure a threshold value for EMR result validity and receive, from a user equipment (UE), a first measurement value corresponding to a first time at or before expiration of a timer associated with idle mode or inactive mode measurements. The base station receives, from the UE, a second measurement value corresponding to a second time when a radio resource control (RRC) connection setup or resume procedure starts. The base station then determines, based on a comparison of the threshold value to a difference between the first measurement value and the second measurement value, whether the EMR result is valid.

Abstract: Techniques discussed herein can facilitate transmission and reference signals (RS) associated with layer-1 (L1) operations outside of a configured carrier bandwidth (CBW) of a user equipment (UE). One example aspect is a UE with one or more processors configured to transmit UE capability information. The UE capability information includes a frequency separation threshold, where the frequency separation threshold represents a frequency separation from a CBW of the UE. The one or more processors are further configured to receive a RS within the frequency separation threshold and outside of the CBW, and subsequently perform a L1 operation based on the RS.
