  • Publication number: 20250151047
    Abstract: The techniques described herein may include solutions for using downlink control information (DCI) to indicate dormancy for secondary cells (SCells). For DCI without a specific field for indicating dormancy for SCells, one or more fields of the DCI may be repurposed to report SCell dormancy. Repurposed fields may be arranged according to radio resource control (RRC) configuration information, a most significant bit (MSB), a least significant bit (LSB), and/or one or more bits being directed to specific SCell dormancy with one or more other bits being directed to SCell group dormancy, subsets of SCells, and/or a pre-defined rule. These and many other features and examples are described herein.

  • Publication number: 20250150852
    Abstract: A user equipment (UE) configures radio resource management (RRM) relaxation in extended discontinuous reception (eDRX) in cases with or without a paging transmission window (PTW). The UE determines whether an eDRX cycle is configured as being greater or less than 10.24 seconds; determine whether the UE has met legacy RRM relaxation criteria for a relaxation scaling factor k; and configures RRM relaxation timing based on use of a paging transmission window (PTW) and the relaxation scaling factor k.

  • Publication number: 20250150985
    Abstract: Techniques are provided for a network-controlled repeater (NCR) to share power during the simultaneous transmission of a control link and backhaul link. When the total power for transmitting via the control link and the backhaul link are below a maximum power for transmission, the NCR can use the calculated transmission powers for transmitting each link. Otherwise, the NCR can apply a relative priority to the links, a default priority to each link, a stepwise reduction of power, or a power sharing factor. A power sharing technique can be based on whether there is overlap between the links on the same time symbol, where the same or different beams are used for each link, and/or whether a priority flag for an access link is being used. These and many other features and examples are described.

  • Publication number: 20250150926
    Abstract: Mechanisms are provided for a user equipment (UE) to perform a handover operation from a first base station in a serving cell to a second base station in a target cell under conditions. The UE can receive a conditional handover instruction including a channel quality condition for the handover operation and an additional condition for the handover operation. The UE may determine an operation order between testing the channel quality condition and testing the additional condition, and further determine whether the channel quality condition or the additional condition is met or not. In response to a determination that the channel quality condition is met and a determination that the additional condition is met, the UE can perform the handover operation to handover the UE from the first base station to the second base station.

  • Patent number: 12294434
    Abstract: Some embodiments include an apparatus, method, and computer program product for implementing Channel State information (CSI) feedback for multi-Physical Downlink Shared Channel (PDSCH) transmissions in a wireless communication system. Some embodiments enable a user equipment (UE) to determine Channel Quality Indicators (CQI) and/or Precoding Matrix Indicators (PMI) for multi-PDSCH transmissions that account for effects of a duration of the multi-PDSCH transmission including the maximum interval between the first and last PDSCH transmissions on the CQI and PMI determinations. Some embodiments include a base station that detects a need for a change in a beam direction and adjusts the beam direction accordingly based on the PMI determinations. Some embodiments enable a desired hybrid automatic repeat request (HARQ)-ACK feedback transmission from a single multi-PDSCH transmission.

  • Publication number: 20250142504
    Abstract: Systems and methods for performing timing advance (TA) validation at a user equipment (UE) for a TA to be used when transmitting a configured grant small data transmission (CG-SDT). Mechanisms for bounding one or more measurement windows during which one or more synchronization signal blocks are measured during a reference signal received power (RSRP) measurement method of the TA validation are discussed, and may be set using information corresponding to timing drift due to relativistic effects, clock differences between a UE and a base station, and/or information about a UE discontinuous reception (DRX) cycle. Further, time interval limitations between various events attendant to such an RSRP measurement method are discussed as being determined using information corresponding to timing drift due to relativistic effects, clock differences between a UE and a base station, information about a DRX cycle used at the UE, and/or a maximum TA timer duration.

  • Patent number: 12289645
    Abstract: Methods and systems are disclosed for a UE of a wireless communication network to recover from MCG radio link failures in a MR-DC system when the SCG is deactivated or otherwise not enabled. When a MCG link failure is detected and the SCG is deactivated, the UE may activate the SCG for the UE to use the SCG link to transmit and receive signaling messages or data as part of the MCG failure recovery procedure. When the MCG link failure is detected and the UE is configured to add the SCG upon the satisfaction of certain condition, but the condition has not occurred, the UE may check to determine whether one condition is MCG failure and whether the radio link quality of the SCG exceeds a threshold. If the radio link quality of the SCG exceeds the threshold, the UE may apply the SCG configuration to add the SCG.
