Abstract: Methods, systems, and devices for wireless communications are described. A receiving device may use enhanced techniques for determining whether a transmission is scheduled to include new data when a mode for reporting acknowledgment feedback is disabled for one or more hybrid automatic repeat request (HARQ) processes used by the receiving device. An enhanced technique may include increasing a quantity of bits used to convey an indication of whether a scheduled data transmission includes new data. An enhanced technique may include monitoring a duration between transmissions scheduled by different control messages based on a timing parameter that indicates a maximum time between transmissions of a data set and corresponding transmission including the data set.

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: Apparatus, methods, and computer-readable media for facilitating multiplexing of time-varying DMRS within a symbol are disclosed herein. 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.

Abstract: Methods, systems, and devices for wireless communication are described to support guard interval (GI) configurations for multiple links. For example, a user equipment (UE) may determine a first GI duration for a first transmission reception point (TRP) and a second GI duration for a second TRP, when the UE is operating in a multi-TRP mode. The UE may determine the GI durations based on a difference in timing between signal reception from the first and second TRPs and may transmit a signal to one or both of the TRPs to indicate the GI durations. Based on the indicated GI durations, the first and second TRPs may transmit signaling to the UE that includes or implements the corresponding GI duration for each TRP. For example, the signaling may include a GI appended at the end of each symbol period that has a GI duration corresponding to the respective TRP.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) and a base station may communicate according to a combined cyclic prefix and guard interval-based waveform format. The base station may transmit control signaling to the UE. The control signaling may indicate a slot configuration. The UE may identify a format of a slot including a set of symbols based on the slot configuration. The format may indicate that a first portion of a first symbol of the set of symbols includes at least two cyclic prefixes and a second portion of the first symbol includes a guard interval. The UE and the base station may perform wireless communications during the first symbol in accordance with the format.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a differential UE-specific timing advance (TA) based at least in part on a difference between a first UE-specific TA associated with a current global navigation satellite system (GNSS) position fix and a second UE-specific TA associated with a previous GNSS position fix. The UE may transmit, to a non-terrestrial network (NTN) node, an uplink message at a time that is based at least in part on the differential UE-specific TA. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify a time period during which the UE is configured to receive grants scheduling communications for the UE, wherein the grants are associated with a first grant format type. The UE may determine that the grants include a feedback process identifier exceeding a threshold value. The UE may maintain a power saving state of a discontinuous reception procedure for a feedback process associated with the feedback process identifier during the time period based at least in part on the feedback process identifier exceeding the threshold value.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a waveform threshold for selecting a waveform type for transmitting a message of a random access procedure. The UE may select the waveform type for the message of the random access procedure based on the waveform threshold and a value associated with a power of signals received at the UE. The UE may transmit the message of the random access procedure to a network entity according to the waveform type selected for the message.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may configure a set of transmission parts each including different sets of time domain resources or different sets of frequency domain resources, or both, and may specify a waveform type for each of the set of transmission parts. In some examples, the base station may configure the set of transmission parts for a user equipment (UE) and, accordingly, the UE and the base station may communicate over a transmission part of the set of transmission parts via signaling that is based on a waveform type that is associated with the transmission part over which the UE and the base station communicate. The base station may control over which transmission part of the set of transmission parts the UE and the base station communicate via a configured timer or via explicit activation and deactivation signaling.
