  • Patent number: 12369060
    Abstract: Methods, apparatuses, and systems are disclosed for configuring measurement timings in connection with UEs that are capable of signaling whether a measurement gap (MG) is needed to measure a target frequency carrier. For example, a measurement period may be determined for the target frequency carrier based on the UE indicating that it supports per-frequency range (FR) MGs, and determining that the FR of the target frequency carrier does not include any current serving cell(s). If the UE indicates that no MG is needed to measure the target frequency carrier, then the measurement period may be based on an SMTC, and may be further based on a predefined effective measurement gap repetition period (MGRP). If the UE indicates that a MG is needed, then the measurement period may be based on the SMTC, and may be further based on the effective MGRP or a per-UE MGRP.

  • Patent number: 12363746
    Abstract: Techniques discussed herein can facilitate inter-cell interference mitigation. One example aspect is a user equipment (UE), configured to receive a network assistance indication associated with an interfering signal, where the interfering signal interferes with a physical downlink shared channel (PDSCH) transmission. A time resource allocation of the interfering signal is different than a time resource allocation of the PDSCH transmission. The UE is further configured to determine an interference and noise covariance estimation mechanism based on the network assistance indication then perform interference and noise covariance estimation based on the noise covariance estimation mechanism. The UE is further configured to perform mitigation of the interfering signal using a mitigation mechanism based on the interference and noise covariance estimation.

  • Patent number: 12336017
    Abstract: A user equipment (UE), baseband processor or other network device (e.g., base station, next generation NodeB, etc.) can operate to configure a hand over (HO) or a primary secondary cell (PSCell) addition based on a channel state information reference signal (CSI-RS) based contention free random access (CFRA) procedure. A CSI-RS rough timing of a CSI-RS position can be determined based on a synchronization signal block (SSB) associated with a CSI-RS or a serving cell timing. A CFRA transmit timing can be determined based on the CSI-RS rough timing or a CSI-RS fine timing that is derived from a timing and frequency (T/F) tracking operation on the CSI-RS. Reference signal receive power (RSRP) measurement(s) can be made on the CSI-RS for performing the CSI-RS based CFRA procedure with transmissions according to the CSI-RS transmit timing of the CSI-RS that satisfies an RSRP threshold.

  • 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: 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.
