Abstract: Wireless communications systems may support flexible waveform configuration for autonomous uplink transmissions. A base station may transmit broadcast signaling (e.g., a system information block (SIB)) indicating waveform configuration information for an autonomous uplink transmission by a user equipment (UE). In some cases, the broadcast signaling may include a waveform configuration field (WCF) that may indicate whether flexible waveforms for autonomous uplink are supported, may configure a waveform type, may indicate waveform configuration mapping rules, etc. As such, a UE may identify whether flexible waveform configuration for autonomous uplink is supported, and may determine waveform types for autonomous uplink transmissions based on waveform type configuration information from a base station (e.g., which may include an indication of whether flexible waveform configuration is supported, an indication of waveform type/scenario mapping rules, etc.), one or more LUTs, identified autonomous uplink scenarios, autonomous uplink transmission parameters, or some combination thereof.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may support configured grant (CG)-small data transmission (SDT) procedures. To improve CG-SDT, the UE may validate measurement resources for timing advance (TA) validation and CG resource validation. The UE may receive a radio resource control (RRC) release message indicating CG resources and information that may be used for TA and CG resource validation, and the UE may receive measurement information based on one or more reference signals. In some cases, the UE may validate the measurement information and use it to perform a TA command (TAC) validation procedure. In some other cases, the UE may validate the measurement information and use it to perform a communication resources validation procedure. While in an inactive state, the UE may transmit an uplink communication using the validated TA and the validated communication resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive signaling to operate in a radio resource control (RRC) inactive or idle state. The UE may receive a phase tracking reference signal (PTRS) configuration for a physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) communication when the UE is operating in the RRC inactive or idle state. Numerous other aspects are described.

Abstract: A UE may receive an indication of a first assignment of a first PDSCH via a PBCH from a network entity. The first PDSCH may include at least a first portion of a SIB. The UE may receive the first portion of the SIB via the first PDSCH from the network entity based on the first assignment of the first PDSCH. The first portion of the SIB may include access control information for the network entity and the assignment for a second portion of the SIB. The UE may identify whether the UE is permitted to access the network entity based on the access control information for the network entity.

Abstract: In an aspect, a relay UE transmits sidelink reference signals for positioning (SL-RS-P) off first and second reconfigurable intelligent surfaces (RISs). The target UE measures the reflected SL-RS-Ps. In an aspect, the SL-RS-Ps may be associated with configurations that are configured by a base station. In an aspect, a position estimation entity may obtain measurement information associated with the reflected SL-RS-Ps and determine a position estimate of the target UE based at least in part upon the measurement information.

Abstract: Techniques for reconfigurable intelligent surface (RIS)-assisted calibration for timing errors in wireless nodes may comprise obtaining a set of wireless reference signal measurements comprising: first, second, third, and fourth measurements of reference signals traveling between the mobile device, a first wireless node, and a second wireless node, wherein a portion of the reference signals are reflected by the RIS while traveling between the mobile device and the first or second wireless node. A differential value comprising a difference between the third measurement and the fourth measurement is also obtained. Determining a position estimate of the mobile device may then be performed, based at least in part on the set of wireless reference signal measurements, the differential value, and a respective location of each of the first wireless node, the second wireless node, and the RIS.

Abstract: Fallback procedures for user equipments (UEs) are described that provide efficient fallback to a four-step random access procedure from a two-step random access procedure. For example, after transmitting a first message of a two-step random access procedure, a UE may start a fallback timer or counter and monitor for a second message of the two-step random access procedure for the duration of the fallback timer or counter. At the expiration of the fallback timer or counter, the UE may fall back to a four-step random access procedure. In some cases, the UE may transmit multiple repetitions of the first message and monitor for responses after transmitting the repetitions or after each repetition. Additionally, or alternatively, the base station may transmit an explicit signal to the UE that may signal to the UE to perform a fallback procedure at a beginning or middle of a random access procedure.
