  • Publication number: 20250176065
    Abstract: Apparatuses, systems, and methods for inactive mode DRX cycle and/or measurement cycle determination, e.g., such as for radio resource management (RRM) in inactive mode, e.g., in 5G NR systems and beyond, including systems, methods, and mechanisms for determining a DRX cycle for cell detection and measurement. An inactive mode DRX cycle periodicity may be determined by scaling a periodicity of an idle mode DRX cycle, an inactive mode eDRX cycle, an idle mode eDRX cycle, and/or by a paging occasion cycle. The scale factor may be predefined, specified by a standard, and/or configured via higher layer signaling. Additionally, whether an inactive mode DRX cycle is determined by scaling a periodicity of an idle mode DRX cycle, a paging occasion cycle, an inactive mode eDRX cycle, or an idle mode eDRX cycle may depend on one or more conditions associated with a UE.

  • Publication number: 20250167952
    Abstract: Systems and methods provide Layer 1 reference signal received power (L1-RSRP) measurement and transmission configuration indication (TCI) state switching. A cellular communications network determines a plurality transmission reception points (TRPs) configured for high speed train (HST) communication using millimeter wave (mmWave) signals, and generates a synchronization signal block (SSB) index configuration for the plurality TRPs. The SSB index configuration uses non-adjacent SSB indexes between the plurality of TRPs. A user equipment (UE), in response to entering a HST mode, performs L1-RSRP measurement sharing for SSBs received from different TRPs. A scheduling restraint may be used for TCI state switching. Autonomous UL TA adjustment timing may also be used.

  • Publication number: 20250133592
    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.

  • Patent number: 12284016
    Abstract: Techniques for changing a Transmission Configuration Indication (TCI) state by a user equipment (UE) operating in a wireless communications system are provided. The UE receives a first message including a TCI state change command from a network and determines, based on the first message, whether a time offset/frequency offset (TO/FO) and a reception (Rx) beam for a new TCI state are known by the UE. Based on the determination, the UE calculates a time delay of the UE to be prepared to receive a reference signal with the new TCI state, generates a second message indicating the time delay of the UE for the new TCI state, and transmits the second message to the network.
