  • 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.

  • Publication number: 20250106842
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may account for the application of orthogonal cover coding (OCC) to an uplink transmission when determining the transport block size (TBS) for the uplink transmission. OCC may be used to multiplex transmissions from multiple UEs and may involve spreading information. Described techniques may involve accounting for the spreading of information bits when determining the TBS for the uplink transmission to which OCC is applied. Sub-physical resource block (sub-PRB) frequency allocations may be provided for uplink transmissions. The UE may account for the allocated quantity of sub-carriers when determining the quantity of information bits. To indicate a sub-PRB, the UE may be configured to reinterpret one or more fields of an existing downlink control information (DCI) format as indicating the allocated sub-carriers, or a new DCI format may be configured that includes fields for indicating a sub-PRB allocation.
