Abstract: Aspects herein relate to wireless devices, circuits, and methods for indicating, by a wireless device, to a wireless station, an ability to support semi-persistent (SP) measurement gap (MG) configuration; receiving, from the wireless station, a SP MG configuration; receiving, from the wireless station, a message to activate the SP MG configuration; performing, in response to receiving the message to activate the SP MG configuration, a target carrier frequency measurement, wherein the target carrier frequency measurement is performed in accordance with the activated SP MG configuration; receiving from the wireless station, a message to deactivate the SP MG configuration; and discontinuing, in response to receiving the message to deactivate the SP MG configuration, the performance of the target carrier frequency measurement. In other aspects, the wireless device may indicate, to the wireless station, an ability to support aperiodic (AP) MG configuration, which does not require explicit deactivation by the wireless station.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform SRS transmission when a UE supports SRS Tx antenna port switching. In an example, a determination is made about whether a scheduled SRS transmission impacts a scheduled DL reception given the SRS Tx antenna port switching. If so, the SRS transmission and/or the DL reception are changed. In a further example, the UE can supports an SRS TA capability in conjunction with the SRS Tx antenna port switching capability. In this example, SRS TA can be applied to a scheduled SRS transmission.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform measurements on reference signals based on measurement gaps. In an example, a device supports a frequency range that includes frequencies equal to or larger than 52.6 GHz. Measurement gap capability information is used to indicate and/or determine whether a measurement gap is supported for this frequency range. If so, measurement gap configuration can be defined and can include a measurement gap length and/or a measurement gap repetition period defined based on the frequencies being equal to or larger than 52.6 GHz.

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: The present application relates to devices and components including apparatus, systems, and methods to perform cell reselection. In an example, timing requirements for synchronization signal processing are defined based on a beam sweeping capability of the device. Synchronization signals are received and processed according to the timing requirements to complete a cell reselection procedure. In another example, location data of the device is used to look up a database of cell identifiers. A cell identifier is determined based on the look-up and a cell reselection procedure is performed using the cell identifier.

Abstract: When a user equipment (UE) encounters a radio link failure condition, the UE may transmit a radio link failure report to a network. The report may include information defining the radio link monitoring (RLM) resources of a current RLM configuration. The information may take the form of a resource bitmap or a list of resource identifiers/indices. The network may use the information (and radio resource management measurements) to determine whether the radio link failure occurred due to misconfiguration of RLM resources for the UE. In cases where the network does not provide RLM configuration, the UE may omit the bitmap (or list), or populate the bitmap with all zeros, or populate the bitmap (or list) according to a currently active Transmission Configuration Indication (TCI) state, which is indicated by downlink control information (DCI).

Abstract: Apparatuses, systems, and methods for beam reporting to facilitate multiple transmission and reception points, multi-TRPs, transmission schemes. A UE may receive, from a base station a configuration to report a beam quality based on at least one of a first reporting scheme and a second reporting scheme or a configuration of measurement resources for each TRP of a plurality of TRPs. The UE may report the beam quality based on the configuration or L1 measurements for multiple beam pairs and a recommended and/or assumed transmission scheme based on the configured measurement resources. The first reporting scheme may include the UE reporting at least one L1 measurement for multiple beams and the second reporting scheme may include the UE reporting at least one L1 measurement for multiple beam pairs. The recommended and/or assumed transmission scheme may be a non-coherent-joint transmission (NC-JT) transmission scheme and/or a single frequency network (SFN) transmission scheme.
