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: A base station is configured to receive channel state information (CSI) from a user equipment (UE). The base station transmits configuration information including one or more interference measurement resources (IMRs) allocated for measurement by the UE, receives a reference CSI report from the UE, receives a new CSI report including interference and noise power fluctuation feedback from the UE and selects a modulation and coding scheme (MCS) for the UE based on at least the interference and noise power fluctuation feedback and the reference CSI report.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing mechanisms for reducing interruption lengths for Sounding Reference Signal (SRS) antenna switching. For example, some aspects of this disclosure relate to a user equipment (UE) configured to determine one or more symbols during which the UE is configured to perform an antenna switch for a Sounding Reference Signal (SRS) transmission. The UE is further configured to generate an indication message including an indication of the one or more symbols and transmit, using the transceiver, the indication message to the base station.

Abstract: Methods, apparatuses, and systems are disclosed for determining prioritization of subsequent small data transmissions (SDTs) and measurement occasions for a UE in inactive mode. The UE may determine that one or more subsequent SDT occasions of an SDT session conflict in time with one or more measurement occasions scheduled during the SDT session. In response, the UE may determine which of the subsequent SDT occasions to utilize or forgo, and which of the measurement occasions to utilize or forgo. The procedure for making such determinations may vary based on the type of measurement occasion involved in the conflict. For example, the procedure may vary based on whether the measurement event pertains to inter-frequency neighbor cell measurement occasions, inter-RAT neighbor cell measurement occasions, intra-frequency neighbor cell measurement occasions, serving cell downlink measurement occasions, and/or serving cell paging occasions.

Abstract: Systems, methods, and circuitries are disclosed for avoiding slot decoding failure due to beam switching of a common beam. In one example, a baseband processor for a user equipment (UE) is configured to cause the UE to perform various operations. The operations include receiving a data transmission on a plurality of component carriers (CCs) carrying corresponding symbols on a common beam; receiving a beam switch command from the network node, wherein the beam switch command is configured to cause the UE to switch a receiving (RX) beam at an end boundary of a first symbol of the data transmission; identifying one or more symbols for restricted scheduling in one or more CCs of the plurality of CCs based on the beam switching on the first symbol; and ignoring the one or more symbols identified for restricted scheduling for decoding of the data transmission.

Abstract: A user equipment (UE) supports an independent measurement gap configuration. The UE transmits an indication to a currently camped cell indicating that the UE supports an independent measurement gap configuration for new radio in an unlicensed spectrum (NR-U), receives measurement gap configuration information from the currently camped cell, configures a measurement gap pattern based on the measurement gap configuration information and receives a signal from a cell during a measurement gap of the measurement gap pattern.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform measurements on reference signals or synchronization signal. In an example, timing requirements for performing such measurements can be dynamically changed depending on, at least, a measurement on one of the reference signal or the synchronization signal.

Abstract: Serving cell measurements at a reduced capability UE in idle mode in FRI includes identifying an eDRX cycle length associated with the reduced capability UE is longer than or equal to 20.48 s and shorter than or equal to 10, 485.76 s. The eDRX cycle length includes a DRX cycle length. A measurement period associated with a serving cell of the reduced capability UE is determined to occur within a single PTW of the eDRX cycle. The measurement period includes measurement samples to be performed within the single PTW. A length of the single PTW is determined based on a product of the DRX cycle length and a sample scaling factor associated with the measurement samples. The length of the single PTW comprises a multiple of 1.28. Serving cell measurements are performed during the single PTW. The serving cell measurements include each of the measurement samples associated with the measurement period.
