  • 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: 20250150165
    Abstract: Approaches are described to enhance radio link monitoring and link recovery for the integration of non-terrestrial networks (e.g., satellites) into next generation wireless communication networks. Certain approaches describe the modification of block error rate threshold requirements based on the particulars of the satellites involved, and the procedure for making those modifications. Other approaches describe the modification of the evaluation period based on the particulars of the satellites involved, and the procedure for making those modifications. In making these modifications, user-equipment (UE)-specific margins are also considered. In addition, modifications to the procedure for higher priority cell search are also described when non-terrestrial wireless communication networks are involved.

  • 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: 12289610
    Abstract: A network may transmit either beam deployment information or beam number information to a user equipment (UE) carried on a train and configured for operation in the millimeter wave band. The deployment information may include deployment related distance parameters or azimuth angle spread parameters. The beam number information may indicate a number of network beams associated with a current cell. The UE may determine a number of UE receive beams based on deployment information or the network-indicated number of network beams. The UE may transmit feedback to the network, indicating the number of UE receive beams. Alternatively, the network may send a configuration message indicating a first number of UE receive beams to the UE, which the UE may treat as an upper bound or lower bound in its determination of a desired number of UE receive beams. The UE may transmit the desired number to the network.

  • 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.
