    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: The present disclosure relates to apparatus, methods, computer-readable storage medium and computer program product for high speed train measurements and signaling. A wireless device, comprising: at least one antenna; at least one radio coupled to the at least one antenna; and a processor coupled to the at least one radio; wherein the processor is configured to: receive, via the at least one radio, at least one Radio Resource Control (RRC) signaling from a cellular base station, the at least one RRC signaling at least comprises one or more information element (IE) of a group of IEs, wherein, the group of IEs at least includes a first IE indicating to enable or disable enhancement on a Secondary Cell (SCell) in Frequency Range 2 (FR2), and a second IE indicating to enable or disable enhancement on a Primary Secondary Cell (PSCell); and perform enhancement on one or more corresponding cells in response to the received at least one RRC signaling, wherein, the enhancement comprises determining a reduced time period for Primary Synchronization Signal (PSS)/Secondary Synchronization Signal (SSS) detection and/or determining a reduced time period for intra-frequency measurements.

    Abstract: Systems and methods for determining a timing of a random access channel (RACH) occasion (RO) used to transmit a contention free random access (CFRA) preamble triggered by the receipt of a physical downlink control channel (PDCCH) order in a PDCCH are disclosed herein. A user equipment (UE) receives the PDCCH order and determines a timing offset value between the RO and a signal (e.g., a synchronization signal block (SSB), the PDCCH, a reference signal, etc.) to be used as a timing source. The UE also determines the arrival time of the signal to be used at the timing source. The UE then determines a time of the RO (during which the CFRA preamble will be transmitted) according to the arrival time and the timing offset value. Timing advance (TA) value(s) may also be accounted for as part of such a determination.
