  • Patent number: 12193012
    Abstract: An approach for wireless communications to support reduced capability New Radio (NR) with larger available control resource sets (CORESET) bandwidths. Examples include a frequency-hopping CORESET with a predefined hopping pattern configured by higher layers, such as RRC signaling or MAC Control Element (CE) on a per CORESET per UE or purely per UE basis. Frequency hopping patterns for CORESET transmissions include the use of PRBs for CORESETs that are mirrored with respect to the central frequency of active bandwidth part (BWP), and the use of a random parameter to step through the frequency pattern. The sub-band location of the physical downlink shared channel that is scheduled by the physical downlink control channel may be indicated using the DCI format, or may be based on a last slot for PDCCH transmission.

  • Publication number: 20250008538
    Abstract: Embodiments are disclosed for capability reporting for antenna switching, AS, sound reference signals, SRS. A user equipment (UE) can transmit a capability report for AS SRS that includes a plurality of receive antenna (e.g., six or eight receive antenna), and receive SRS instructions based on the capability report. The UE can transmit a first temporary capability reduction for a duration, and transmit a first SRS according to the first temporary capability reduction and the SRS instructions, while maintaining phase continuity. To maintain phase continuity, the UE can calibrate one or more SRS ports participating in the AS SRS to transmit with substantially a same transmit power. The UE can determine that a second SRS overlaps an other transmission in a time domain, determine that the other transmission has an absolute priority over the second SRS, and transmit the other transmission but not the second SRS.

  • Patent number: 12184372
    Abstract: A user equipment (UE), or other network component can operate to configure channel state information (CSI) feedback in response to receiving a CSI-reference signal (CSI-RS) according to a hierarchical precoding scheme that selectively reduces a feedback overhead associated with the CSI feedback. The UE can operate to divide and further sub-divide a frequency band (e.g., a wideband, or particular frequency part) into a precoding hierarchy to generate precoders for conveyance to a base station, eNodeB (eNB), or next generation NodeB (gNB) via the CSI feedback.

  • Patent number: 12185088
    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: Methods and devices for a UE to multiplex uplink control information (UCI). The UE establishes a connection with a base station. The UE determines whether to multiplex first UCI by first identifying whether intra-priority timing overlap exists between the timing resources of the first UCI and a PUSCH with the same priority. Subsequently, the UE identifies whether inter-priority timing overlap exists between the timing resources of the first UCI and a second PUCCH with a different priority from the first PUCCH. Finally, the UE identifies whether the timing resources of the first UCI overlap with a second PUSCH with a different priority than the first PUCCH. The UE multiplexes the first UCI based on the determination whether to multiplex the first UCI, and transmits the multiplexed first UCI to the base station.
