Abstract: In some aspects, a method for a user equipment (UE) is provided. In some examples, the UE determines a signal quality for communicating with a node. The UE determines a coverage level based on the signal quality, wherein the coverage level indicates resources to be used for communicating with the node. The UE determines a maximum repetition level and a repetition value, based on the coverage level, for communicating with the node. The UE generates a multibit repetition range identifier that indicates the repetition value based on the maximum repetition level. The UE transmits the multibit repetition range identifier.

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).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may map uplink control information (UCI) bits and uplink shared channel (UL-SCH) data bits to a first subset of resources associated with a physical uplink shared channel (PUSCH). The UE may copy symbols associated with the UCI bits and the UL-SCH data bits from the first subset of resources to one or more remaining subsets of resources. The UE may apply an orthogonal cover code (OCC) across a plurality of subsets of resources, including the first subset of resources and the one or more remaining subsets of resources, associated with the PUSCH. The UE may transmit, based at least in part on the OCC applied across the plurality of subsets of resources, multiplexed UCI bits and UL-SCH data bits. 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.

Abstract: A UE may include IoT NTN device, and the UE may acquire the GNSS location to perform the time/frequency pre-compensation. A NAS layer of the UE may initiate a connection request procedure based on the GNSS fix procedure at one or more lower layer of the UE. A network may transmit a paging request to the UE, and manage a paging response timer based on the GNSS fix procedure at the UE.

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) sequence, wherein the OCC sequence is associated with a frequency domain OCC-based physical uplink shared channel (PUSCH) multiplexing. The UE may transmit a PUSCH transmission based at least in part on the configuration, wherein the OCC sequence is applied to one or more symbols associated with the PUSCH transmission. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. that support preconfigured uplink resources (PUR) in wireless communications. A base station may communicate that support for PUR is available, and may allocate PUR resources to a user equipment (UE) based on requests from the UE. The UE may receive an indication that the base station supports PUR, such as via a system information block (SIB), determine to request PUR, and transmit a PUR request message to the base station. A PUR response from the base station may indicate configuration, or reconfiguration of PUR allocation for the UE that may be used for uplink transmissions, or release of the PUR allocation.

Abstract: This disclosure provides systems, methods and apparatus for enabling multi-TRP transmission in non terrestrial networks. In one aspect, a user equipment receives a first reference signal from a first satellite transmission reception point (TRP) at a first timing and receives a second reference signal from a second satellite TRP at a second timing. The first timing is synchronized with the second timing at a first geographic location. The user equipment receives a third reference signal from the first satellite TRP at a third timing and receives a fourth reference signal from the second satellite TRP at a fourth timing. The third timing and the fourth timing are synchronized at the user equipment. The user equipment receives an indication of a timing offset of the fourth reference signal with respect to the second reference signal and uses the third and fourth reference signals as a quasi colocation (QCL) source.

Abstract: Certain aspects of the present disclosure provide techniques for signaling a scheduling offset for non-terrestrial networks (NTNs). In one aspect, a method for wireless communications by a user equipment (UE) includes receiving first signaling indicating a first part of a scheduling offset associated with a common timing advance (TA); receiving second signaling indicating a second part of the scheduling offset; and transmitting an uplink transmission based on the first and second parts of the scheduling offset.
