Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may selectively transmit, to a network entity, a request for a dedicated system information block type 1 (SIB1) for a target cell based at least in part a determination of whether an SIB1 request criterion is satisfied for an idle state cell reselection from a source cell to the target cell. The UE may receive, from the network entity, an indication of one or more target cell SIB1 parameters included in the dedicated SIB1 for the target cell, based at least in part on transmitting the request for the dedicated SIB1 for the target cell. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive information that indicates whether to perform a first random access channel (RACH) procedure for a non-terrestrial network or a second RACH procedure for a terrestrial network, wherein the first RACH procedure is configured to support a larger number of UEs contemporaneously performing a RACH procedure than the second RACH procedure. Responsive to the information indicating that the UE is to perform the first RACH procedure, the UE may perform the first RACH procedure. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive first configuration information indicating a first guard interval associated with sidelink communications. The UE may transmit, to a base station and another UE, a first sidelink communication using the first guard interval. The UE may transmit, to the base station and using a second guard interval having a second length that is different from a first length of the first guard interval, an uplink communication. Numerous other aspects are described.

Abstract: Disclosed are techniques for positioning. A receiver receives complementary timing information associated with the positioning reference signals (PRS) of a repetition of a PRS sequence. The complementary timing information distinguishes a repetition of a PRS sequence from remaining repetitions of the PRS sequence. Based on the complementary timing information associated with different PRS from different non-terrestrial vehicles indicating that the PRS were transmitted during the same radio frame, the receiver can determine an observed time difference of arrival (OTDOA) between the PRS received from the respective non-terrestrial vehicles.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a wireless device maps data, a unique word (UW) sequence, and a suppression signal to a set of reserved time-domain resources based on a time-domain resource mapping and reservation rule to produce DFT input data. DFT processing is performed on the DFT input data to produce IFFT input data. IFFT processing is performed on the IFFT input data to produce the GI-based waveform with a data part (e.g., non-zero part) and a tail part (e.g., zero tail part). The wireless device may further transmit the GI-based waveform.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of an initial downlink bandwidth for the UE. The UE may receive, via a master information block (MIB), configuration information for a control resource set (CORESET) associated with physical downlink control channel (PDCCH) monitoring for initial access, where the configuration information indicates a frequency domain resource allocation for the CORESET, and where the frequency domain resource allocation for the CORESET is at least partially outside of the initial downlink bandwidth. The UE may receive one or more PDCCH messages associated with the CORESET based at least in part on at least one of modifying a resource mapping of the CORESET or modifying the initial downlink bandwidth. Numerous other aspects are provided.

An example method for wireless communication at a receiving device includes receiving a first symbol of a single carrier waveform, the first symbol including a first set of DMRS resources. The example method also includes receiving a second symbol of the single carrier waveform, the second symbol including a second set of DMRS resources, the second set of DMRS resources associated with at least one of a DMRS starting location and a DMRS duration that is different than the first set of DMRS resources.
