  • Publication number: 20240163738
    Abstract: Apparatus and method are provided for a user equipment (UE) to perform measurement operations for a handover procedure including target NR Primary Secondary Cell (PSCell) change or addition. The measurements of a target PSCell are performed in accordance with a synchronization signal/physical broadcast channel (SS/PBCH) block measurement time configuration (SMTC) included in a measurement object received from a base station (BS). A source primary cell (PCell) is used for reference timing of the SMTC if the measurement object is configured by the source PCell on same frequency and subcarrier spacing of the target PSCell. A source PSCell is used for reference timing of the SMTC if the measurement object is configured by the source PSCell on same frequency and subcarrier spacing of the target PSCell.

  • Publication number: 20240162976
    Abstract: A user equipment (UE), a base station (e.g., next generation NodeB (gNB)), or other network component can operate to configure a beam failure recovery (BFR) timing based on a time offset and a number of symbols in a BFR procedure, as well as enable beam switching and bandwidth part (BWP) switching to be correlated. A beam failure recovery request (BFRQ) can be processed or transmitted in response to a detection of a beam failure. A beam failure recovery response (BFRR) can be generated via a physical downlink control channel (PDCCH) based on at least four slots after the BFRQ and a time offset for a non-terrestrial network (NTN).

  • Publication number: 20240155398
    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.

  • Publication number: 20240155525
    Abstract: Systems, methods, and apparatuses disclosed herein can mitigate interference in a wireless network. These systems, methods, and apparatuses can determine a mode of operation of a base station (BS) within the wireless network. These systems, methods, and apparatuses can select a first time advance (TA) when the BS is operating in a static time division duplex (TDD) mode of operation or a second TA when the BS is operating in a sub-band full duplex (SBFD) mode of operation or a dynamic TDD mode of operation. These systems, methods, and apparatuses can advance signals on an uplink (UL) by the first TA to cause the signals on the UL to be time aligned with other signals from other UEs on the UL at the BS to mitigate inter carrier interference (ICI) at the BS.
