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: A base station may identify a first antenna configuration of the base station and a second antenna configuration of a wireless device. The base station may select one or more codebook-based precoders for communication with the wireless device with LOS MIMO. The one or more codebook-based precoders may include at least one of a Legendre precoder, a block-DFT precoder, a DFT precoder, a block-Walsh precoder, a Walsh precoder, a block-Legendre precoder, a Kronecker Legendre precoder, a Kronecker block-DFT precoder, or a Kronecker block-Walsh precoder. The base station may transmit, to a wireless device, an indication of a second codebook-based precoder for transmission from the wireless device to the base station with LOS MIMO. The base station and the wireless device may communicate with each other with LOS MIMO based on one or more codebook-based precoders.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiving device may transmit, to a transmitting device, a line of sight (LOS) multiple input multiple output (MIMO) channel sounding configuration that indicates one or more channel sounding parameters for a partial sounding procedure associated with an LOS MIMO channel. The receiving device may receive, from the transmitting device, at least one sounding reference signal (SRS) based at least in part on the one or more channel sounding parameters. Numerous other aspects are described.

Abstract: Disclosed are techniques for communication. In an aspect, a network component determines location assistance data comprising information associated with one or more reconfigurable intelligent surfaces (RISs). The network component transmits, to a user equipment (UE), the location assistance data to facilitate one or more location procedures based on the location assistance data. The UE receives the location assistance data and performs the one or more location procedures based on the location assistance data.

Abstract: Methods and apparatuses for wireless communication for line-of-sight Multiple-Input-Multiple-Output (LOS MIMO) are described. A first pilot signal is transmitted to a second device. The first pilot signal is at least one of a constant phase pilot or a linear phase ramped pilot for estimating a misalignment of a second antenna array of the second device with respect to a first antenna array of the first device.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process may include receiving, at a network device (e.g., a user equipment (UE)) from a network entity via a number of sensing streams based on a maximum of Nt-J sensing streams, a waveform including communications resources and sensing resources. The waveform has a rank Nt and J is a number of layers scheduled for multiple-input multiple-output (MIMO) communications that is less than Nt. The process may further include processing at least the communications resources of the waveform.

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.

Abstract: Aspects described herein relate to receiving a configuration indicating multiple association rules associating random access preambles and payload formats, selecting, as part of a random access procedure, a random access preamble from the random access preambles for transmitting over a random access occasion, determining, based at least in part on at least one of the association rules in the configuration, a payload format associated with the random access preamble and a corresponding payload resource unit, and transmitting the random access preamble over the random access occasion and, according to the payload format, an associated payload over the corresponding payload resource unit. Multiplexing of payload resource units with same or different payload formats can be performed in time, frequency and code domains, based on the received configuration.
