    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform an access procedure for establishing or reestablishing a connection with a network entity. The UE may transmit, as part of the access procedure, one or more repetitions of a narrowband physical random access channel (NPRACH) preamble to the network entity. Each repetition of the one or more repetitions may include a set of symbol groups, and each symbol group of the set of symbol groups may include a set of symbols used by the UE for transmitting the NPRACH preamble. In some examples, the set of symbols may include a subset of symbols to which an OCC is applied. The set of symbols may be multiplexed with one or more other sets of symbols associated with respective preambles of one or more other UEs.

    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.

    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.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration associated with an orthogonal cover code (OCC), wherein the configuration indicates a multiplexing order, an OCC codeword for multiplexing, and a type of OCC, and the type of OCC is one of: frequency domain OCC (FD-OCC), time domain OCC (TD-OCC), sub physical resource block (sub-PRB) OCC, or sub-slot OCC. The UE may apply, based at least in part on the configuration, the OCC to an uplink transmission. The UE may transmit the uplink transmission with the OCC applied based at least in part on the configuration. Numerous other aspects are described.

    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.
