Abstract: Techniques discussed herein can facilitate inter-cell interference mitigation. One example aspect is a user equipment (UE), configured to receive a network assistance indication associated with an interfering signal, where the interfering signal interferes with a physical downlink shared channel (PDSCH) transmission. A time resource allocation of the interfering signal is different than a time resource allocation of the PDSCH transmission. The UE is further configured to determine an interference and noise covariance estimation mechanism based on the network assistance indication then perform interference and noise covariance estimation based on the noise covariance estimation mechanism. The UE is further configured to perform mitigation of the interfering signal using a mitigation mechanism based on the interference and noise covariance estimation.

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.

Abstract: A UE for a 5G system is to perform a measurement during a network controlled small gap (NCSG). The NCSG includes a first visible interruption length (VIL1), a measurement length (ML), a second visible interruption length (VIL2), and a visible interruption repetition period (VIRP). A UE capability indicates a length of one or both the VIL1 and the VIL2. NCSG pattern information provides the NCSG for the UE, in which the VIL1 and the VIL2 indicate when the UE is not expected to transmit and receive data on a serving carrier, the ML indicates when the UE is expected to transmit and receive data on the serving carrier, and the VIRP indicates a period in which to repeat the NCSG.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform a switch of a TCI state from a serving cell to a neighbor cell. A UE determines whether the state of the neighbor cell is known or unknown and whether the neighbor cell's TCI state is known or unknown. The total delay time to perform the TCI state switch can impacted by this the known/unknown statuses. Other factors can also contribute to the total delay time. The UE may also signal its capability to monitor the TCI state of the neighbor cell and its capability to switch to such a TCI state.

Abstract: Provided is a method for a user equipment (UE), comprising performing, based on acquired information, in at least one of an idle mode and an inactive mode, at least one of an intra-frequency neighbor cell measurement and an inter-frequency neighbor cell measurement. The acquired information comprises at least one of a group of a periodicity of synchronization signal and physical broadcast channel block (SSB)-based measurement timing configuration (SMTC) and a periodicity of SMTC2-long periodicity (SMTC2-LP) and a physical cell identifier (PCI) list of SMTC2-LP.

Abstract: Activating an uplink (UL) gap at a base station may include decoding a user equipment (UE) UL gap capability report received from a UE. A radio resource control (RRC) UL gap configuration may be encoded for transmission to the UE. A power headroom report (PHR) medium access control (MAC) control element (CE) received from the UE may be decoded. The PHR MAC CE may include at least one of a P value or a power management maximum power reduction (P-MPR) value. Decoding the measurement information may include determining that the P value is equal to one or the P-MPR value is greater than zero. Based on determining that the P value is equal to one or the P-MPR value is greater than zero, the UL gap configuration may be implicitly activated.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to provide SCell activation. In one example, an SCell activation procedure may be extended by a duration based on cancelation of CSI-RS reception. In another example, a base station may use particular configuration parameters to avoid cancelation of CSI-RS reception. In yet another example, a UE and a base station may use particular information for a CSI-RS reception/transmission on an SCell that is being activated.

Abstract: Embodiments of the present disclosure enable a user equipment (UE) to performing inter-Radio Access Technology (RAT) measurements. The UE determines whether one or more inter-RAT measurement object (MO) is configured with or without a measurement gap (MG). When the one or more inter-RAT MO is on an NR serving component carrier (CC) with the MG, the UE performs an inter-RAT measurement on the NR serving CC based on whether the MG is fully overlapped or partially overlapped with synchronization signal blocks (SSBs) of a target MO of the one or more inter-RAT MO. When the one or more inter-RAT MO is on the NR serving CC without the MG, the UE performs the inter-RAT measurement on the NR serving CC based on whether a target SSB of the target MO is within or outside an active bandwidth part (BWP) of the NR serving CC.

Abstract: Systems and methods for implementing uplink (UL) gaps to facilitate user equipment (UE) calibration are disclosed herein. A UE determines one or more slot patterns of a slot configuration that is repeated during time division duplex (TDD) communication with a base station. The UE determines a UL gap periodicity (defining periods covering an integer number of repetitions of the slot configuration). The UE then performs UE calibration during one or more semi-persistently configured UL slots of a period of the UL gap periodicity that correspond to UL indication(s) in one or more of a common configuration, a dedicated configuration, and/or a slot format indication (SFI) downlink control information (DCI) for the slot pattern(s) of the slot configuration. Methods of identifying particular semi-persistently configured UL slots of a period to use for the UL gap are also discussed. UL slot indications from dynamic DCI are not used for UL gap purposes.
