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 new radio (NR) capable user equipment (UE) to determine whether to skip cellular measurements using s-Measure configuration based on measurements of a synchronization signal (SS) block (SSB) and/or Channel State Information Reference Signal (CSI-RS) using an s-Measure configuration. For example, an s-Measure configuration can include a reference signal received power (RSRP) value and an indicator whether to apply the value to an NR SS block or a CSI-RS. If the value meets or exceeds the measurement for the indicated signal measurement, the s-Measure is satisfied. For example, in an embodiment, the network configures a single s-Measure configuration (e.g., either an NR SS s-Measure configuration or a CSI-RS s-Measure configuration), which when satisfied the UE does not perform further measurements.

Abstract: Disclosed are methods, systems, apparatus, and computer programs for a coordination mechanism between a network and a user equipment (UE) that is configured to perform cross-link interference (CLI) measurements. In one aspect, a method includes generating a message that indicates a capability of a user equipment (UE) whether to support simultaneous reception of at least one signal associated with cross-link interference (CLI) measurement and at least one signal associated with a serving cell or a neighbor cell of the UE. The method further includes transmitting the message to an access node (AN).

Abstract: A user equipment (UE) is provided having a memory to store a measurement object (MO) that defines a synchronization-signal block based measurement timing configuration (SMTC) occasion. The MO is within a group of MOs that include SMTC configurations that provide fully overlapped SMTC occasions. The UE further includes processing circuitry to determine an inter-frequency cell identification requirement for the group and perform measurements based on the MO to determine whether a cell is detected within the inter-frequency cell identification requirement.

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.
