  • Patent number: 11902937
    Abstract: This disclosure provides details of sequence-based WUS design and signaling, also DCI-based WUS design which also serves as scheduling DCI. For sequence-based WUS there are two variants. A first is based on CSI-RS, that is relatively wide band so the sequence occupies wider band compared to SSB transmission. The second is more akin to the Secondary Synchronization Signal (SSS) type of sequence in that it occupies a narrower band over the entire bandwidth.

  • Publication number: 20240048253
    Abstract: Some aspects include an apparatus, method, and computer program product for beamforming to perform received signal strength indicator (RSSI) measurements in a 5G wireless communications system. This beamforming may apply to RSSI measurements in an unlicensed spectrum. In some aspects, user equipment (UE) may use beam sweeping to analyze multiple received beams and to determine an RSSI measurement. When using beam sweeping, network nodes may use scheduling and/or measurement restrictions to avoid data collisions. These restrictions may apply to multiple active serving cells. In some aspects, a UE may use beam selection to determine an RSSI measurement. For example, the UE may select one or more beams from a serving component carrier (CC). In some aspects, a network node may indicate to the UE which beams to use for the RSSI measurement. In some aspects, the UE may use a frequency domain resource to perform the RSSI measurement.

  • Publication number: 20240031839
    Abstract: Methods and systems are disclosed for a UE to perform measurements of measurement resources transmitted by a network when the UE is configured with multiple concurrent measurement gap patterns (MGPs). The measurement resources may be carried on multiple carrier frequencies. The UE may receive measurement resource configuration parameters identifying time and frequency locations of the measurement resources transmitted on the multiple carrier frequencies. The UE may receive measurement gap configuration parameters for multiple concurrent MGPs specifying measurement intervals that may be used to perform the measurements. The UE may determine a linkage between the measurement resources on a carrier frequency and one of the concurrent MGPs so that the UE may independently measure the measurement resources received on the multiple carrier frequencies using their respectively linked MGPs.

  • Publication number: 20240023159
    Abstract: Systems and methods for determining a timing of a random access channel (RACH) occasion (RO) used to transmit a contention free random access (CFRA) preamble triggered by the receipt of a physical downlink control channel (PDCCH) order in a PDCCH are disclosed herein. A user equipment (UE) receives the PDCCH order and determines a timing offset value between the RO and a signal (e.g., a synchronization signal block (SSB), the PDCCH, a reference signal, etc.) to be used as a timing source. The UE also determines the arrival time of the signal to be used at the timing source. The UE then determines a time of the RO (during which the CFRA preamble will be transmitted) according to the arrival time and the timing offset value. Timing advance (TA) value(s) may also be accounted for as part of such a determination.

  • Publication number: 20240022975
    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.
