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: This disclosure provides systems, methods and apparatuses for switching configurations for uplink transmission switching. A user equipment (UE) may receive, from a network entity such as a base station, a switching configuration for an uplink transmission switching for three or more carriers. The switching configuration may be associated with switching one or more uplink transmission chains of the UE from or to one or more carriers of the three or more carriers within a time period. The switching configuration may be associated with a UE capability. The switching configuration may permit switching from or to one carrier within the time period associated with the UE capability. The switching configuration may permit switching from or to two carriers within the time period associated with the UE capability. The switching configuration may depend on the UE capability, thereby not causing the uplink transmission switching to degrade a performance of the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control messages including information indicative of a resource allocation associated with a discontinuous operation at a serving cell of the UE. The resource allocation may further be associated with at least one non-terrestrial network (NTN) cell serving a coverage area including the UE. The UE may communicate, during an active period associated with the discontinuous operation, data messages via frequency resources of a first frequency band in accordance with the resource allocation associated with the discontinuous operation. The active period at the serving cell may be non-overlapping with a second active period associated with a second discontinuous operation at a second cell. The UE may communicate, during an inactive period associated with the discontinuous operation, signals via frequency resources of a second frequency band in accordance with the resource allocation associated with the discontinuous operation.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a nominal time domain window duration and at least one of a quantity of nominal time domain windows or a quantity of actual time domain windows for demodulation reference signal bundling. The UE may calculate, in accordance with the quantity of nominal time domain windows being a single nominal time domain window or the quantity of actual time domain windows being a single actual time domain window, and in accordance with an indication that antenna switching is enabled, an adjusted nominal time domain window duration in accordance with applying a parameter to the nominal time domain window duration. The UE may calculate an adjusted quantity of nominal time domain windows and may identify a plurality of actual time domain windows. Numerous other aspects are described.

Abstract: Aspects include systems, methods, devices, and non-transitory processor readable storage mediums for managing a broadcast signal of an apparatus for wireless communication. Various aspects may enable an apparatus to send a message using either omnidirectional transmissions or beamformed transmission based on whether the altitude of the apparatus meets an altitude threshold. In some implementations and aspects, the processor of the apparatus may determine a type of the message and may select the altitude threshold based on the determined message type. In some implementations and aspects, the processor of the apparatus may send the message using beamformed transmissions in response to determining that the message is intended for reception by a certain type of second apparatus.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be aboard an aerial vehicle such that the UE is above ground, and in some cases, moving above ground (e.g., flying). The UE may determine to perform an emergency communication procedure (e.g., an emergency call) while the UE meets one or more flying state conditions, where the one or more flying state conditions may be indicative that the UE is in a flying state. The UE may transmit a message to a base station as part of the emergency communication procedure, where the message may be indicative that the UE meets the one or more flying state conditions. The UE may participate in the emergency communication procedure while the UE is in the flying state.

Abstract: Method and apparatus for collision rules between PRS and other downlink channels. The apparatus determines a PRS priority configuration including a priority for a collision between a PRS occasion and a first downlink channel. The apparatus receives an indication that schedules the first downlink channel. The first downlink channel scheduled to potentially collide with the PRS occasion. The apparatus determines that a time interval between the indication that schedules the first downlink channel and the PRS occasion is greater than a first threshold. The time interval is based on a separation between at least a last symbol of the indication and a first symbol of the PRS occasion. The apparatus applies the PRS priority configuration if the first downlink channel collides with the PRS occasion and the time interval is greater than the first threshold.

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 user equipment (UE) switch between carriers of a group of a carriers during uplink communications in accordance with a mapping. For example, the UE may report its capability to a base station for switching between carriers of the group, where the group includes a supplementary uplink (SUL) carrier and two or more normal uplink (NUL) carriers that are each associated with a different radio frequency band. The base station may indicate for the UE to switch to a subset of carriers of the group corresponding to a combination of radio frequency bands for transmission of an uplink message. The UE may switch to at least one carrier of the subset of carriers in accordance with a mapping that is based on the reported capability and may transmit the uplink message on the at least one carrier.
