  • Patent number: 12294442
    Abstract: A method for wireless communication includes validating a PUR configuration in a NTN based on location-related information associated with a satellite. For example, a UE may determine, based on location-related information of a satellite in a non-terrestrial network, whether a preconfigured uplink resource (PUR) configuration is valid. The UE may also transmit, to a base station (BS) via the satellite in response to determining that the PUR configuration is valid, a communication signal in a PUR. For example, the UE may determine, based on the location-related information associated with the satellite, if the parameter satisfies the threshold, and transmit UL data in a PUR occasion based on the determined parameter satisfying the threshold.

  • Publication number: 20250133536
    Abstract: Methods, systems, and devices for wireless communications are described. A non-terrestrial network (NTN) cell may transmit a pre-paging message for which a user equipment (UE) may monitor based on a synchronization signal block (SSB) and a pre-paging configuration. For example, the UE may be configured with a pre-paging configuration for one or more NTN cells that may be used to identify an SS and a CORESET in which to monitor for a pre-paging message. The UE may identify the pre-paging configuration for a specific NTN cell based on a cell identifier for the NTN cell identified based on decoding an SSB from the NTN cell. The UE may identify the CORESET and the SS based on the pre-paging configuration and the resource via which the SSB was received. Thus a UE may receive a pre-paging message from an NTN based on receiving and decoding an SSB in low SINR scenarios.

  • Publication number: 20250126584
    Abstract: A scheduling offset between an uplink and downlink radio frame timing structure of a user equipment (UE) may be updated to provide for more efficient utilization of hybrid automatic repeat request (HARQ) processes in a non-terrestrial network. For instance, different UEs may experience different round trip delays (RTDs) with a non-terrestrial cell. Different UEs may be configured with different scheduling offsets such that scheduling delays may be reduced and HARQ processes identifiers may be reused more rapidly. Additionally or alternatively, wireless communications systems may define one or more separation distances (or timing thresholds) for timing between communications and HARQ processes may be reused based on the separation distance threshold (e.g., such that a satellite may reuse a HARQ process ID for two scheduled communications that have not yet been performed by the UE).

Responsive to identifying an external user is interested in the chat group, embodiments generate and set a current topic representing a conversation in the chat group as an externally hearable topic that is perceivable by the external user and generate a faux multi-person conversation associated with the externally hearable topic that corresponds to a real conversation made by members in the chat group. Further, embodiments assign the faux utterances to chat group members based on a corresponding speaker index and utilize one or more corresponding avatars of the chat group members to present the faux utterances to the external user.

  • Publication number: 20250119250
    Abstract: Methods, systems, and devices for wireless communications are described. A reference signal distribution scheme described herein may allow for the benefits of orthogonal cover codes, and improve mechanisms to identify and address resulting carrier frequency offset. Techniques are described for distributing reference signals (e.g., demodulation reference signals) over a set of resources. The reference signals may be arranged in equi-spaced clusters, where groups of the reference signals per cluster are spaced according to a first timing offset, and where each cluster may be spaced according to a second timing offset. The network may configure the reference signal distribution scheme at various user equipments, indicating values for the timing offset. The user equipments may transmit reference signals according to the indicated scheme.

  • Publication number: 20250113317
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that it is communicating with a particular type of cell (e.g., an air to ground (ATG) cell), and may utilize a timing advance (TA) report format corresponding to the determined cell type. The TA report for an ATG cell may use all 16 bits of a TA report to indicate a TA value according to a small time unit. The TA report for an ATG cell may utilize a subset of bits to indicate a symbol-level TA, and the remainder of bits in the TA report may be unused. The TA report for an ATG cell may be a single octet TA report, including reserved bits and a bit that indicates a format for the TA report, and the TA value. The TA report may include reserved bits and the TA value.
