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: 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: Inter-cell mobility may include decoding a first radio resource control (RRC) reconfiguration message received from a first cell. The first RRC reconfiguration message may comprise a first portion of configuration information for performing a cell change to a second cell. A cell change message received from the first cell may be decoded. The cell change message may indicate that a cell change to the second cell is to be performed. A cell change acknowledgment may be encoded for transmission to the second cell. A second RRC reconfiguration message received from the second cell may be decoded. The second RRC reconfiguration message may comprise a second portion of configuration information for performing the cell change to the second cell. The second portion of configuration information may comprise a remaining portion of configuration information to perform the cell change to the second cell.

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: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for performing radio link monitoring or beam failure detection (RLM/BFD) in, or related to, a new radio (NR) involved network. Various embodiments are directed to adaptive configuration of threshold values for in-sync and/or out-of-sync (IS/OOS) in the NR involved network and adequately performing RLM/BFD. Such RLM/BFD with adaptive IS/OOS configuration may improve measurement accuracy and system performance. Other embodiments may be described and claimed.

Abstract: Systems and methods provide for beam detection in a wireless communication system. An apparatus for a UE may be configured to identify a plurality of CSI-RS resources corresponding to different Tx beams configured for measurement by the UE, measure an L1-RSRP for the plurality of CSI-RS resources, determine a selected Tx beam of the different Tx beams based on measured L1-RSRP values for the plurality of CSI-RS resources, and determine a measurement accuracy of a first L1-RSRP value corresponding to the selected Tx beam based on successful beam detection probability.

Abstract: Techniques discussed herein can facilitate back-off mechanisms for inter-cell mobility. One example aspect is a baseband processor configured to: receive a unified transmission configuration indicator (TCI) from a first serving cell where the unified TCI is associated with a second serving cell; in response to receiving the unified TCI, transmit an ACK message to the first serving cell; communicate with the second serving cell; configure a time window subsequent to transmission of the ACK message; and perform a fallback operation when a dedicated signaling from the second serving cell is not received within the time window.
