Abstract: This disclosure provides systems, methods, and devices for wireless communication that support short control messaging using index modulation on DMRS. In a first aspect, a method of wireless communication includes a base station determining a configuration action for a served user equipment (UE) in communication with the base station. The base station may then generate a short control message associated with the configuration action and map that short control message onto a set of inactive subcarrier resource elements (REs) of a demodulation reference signal (DMRS) sequence. The served UE may then receive the transmitted DMRS sequence and determine the short control message within the set of inactive subcarrier REs of the DMRS sequence. Other aspects and features are also claimed and described.

Abstract: A device generates an estimated size of encoded versions of one or more pictures of video data prior to generating the encoded versions of the one or more pictures. A physical layer of a radio system of the device is configured to send a message to a wireless base station. The message indicates a size value based on the estimated size of the encoded versions of the one or more pictures. The physical layer of the radio system receives an uplink grant notification in response to the message. Based on the uplink grant notification, the physical layer of the radio system sends packets to the wireless base station containing the encoded versions of the one or more pictures.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for adapting or considering a receiver gain when using super-high order modulations for data transmissions. In one aspect, a network entity may transmit a tracking reference signal (TRS) in a first slot adjacent in time to a second slot allocated for one or more data transmissions associated with a high order modulation. A user equipment (UE) may receive the TRS and may adjust a receiver gain based on the TRS before receiving the one or more data transmissions associated with the high order modulation in the second slot. In another aspect, a UE may indicate (e.g., based on a receiver gain at the UE) a type of slot (e.g., shortened slot) or a maximum number of slots in which a network entity may transmit data transmissions with a high modulation order.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may determine a number of resources for next transmissions following a first transmission. For example, a user equipment (UE) may calculate an average mutual information (MI) of a single log likelihood ratio (LLR) and an MI for each code block. The UE may transmit feedback indicating a quantity of resources to achieve a target MI based on the calculated averages. A wireless device may monitor a feedback buffer utilization associated with the UE. A network entity may retransmit existing code blocks or output a transmission using repetition based on the monitoring and utilization thresholds. The network entity may indicate to the UE a latency level code block attribute and increase a quantity of resources for following retransmissions by a boosting factor based on the latency level and a threshold.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques support blind common phase error (CPE) and residual carrier frequency offset mitigation. Generally, the described techniques provide for blind CPE mitigation at a receiving device without a phase tracking reference signal (PTRS) associated with less overhead and improved performance as compared to use of a PTRS to mitigate CPE. A receiving device may receive a shared channel message in a scheduled shared channel allocation in accordance with a PTRS configuration that omits a PTRS allocation based on a capability of the receiving device to apply blind CPE mitigation for shared channel receptions. In some examples, with a single DMRS symbol allocation, blind CPE mitigation for each subsequent data symbol of a shared channel message may be based on the blind CPE estimation for the previous symbol, which may enable robust mitigation of a residual carrier frequency offset.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for determining a constellation configuration for an amplitude phase shift keying (APSK) modulation scheme. The constellation configuration may be based on communication impairment information that is indicative of at least one communication impairment expected to impair a single-carrier waveform communication. Examples of communication impairments may include additive white gaussian noise (AWGN), phase noise, non-linear distortion, or any combination thereof, among other examples. Examples of a constellation configuration may include a quantity of rings in a constellation pattern associated with the APSK modulation scheme, a quantity of constellation points associated the rings, a ring radius associated with one or more rings, a phase offset to one or more rings, and a mapping of data bits to one or more constellation points, among other examples.

Abstract: Methods, systems, and devices for wireless communications are described for optimizing index modulated (IM) communications between a user equipment (UE) and a base station. The UE may identify a quantity of subcarriers for IM communications and transmit a message including an indication of the quantity of subcarriers to the base station. In some examples, the UE may transmit an indication of one or more subcarriers to exclude from IM communications. The base station may receive the indication of the quantity of subcarriers and/or the indication of the blacklisted subcarrier(s) and may determine a number of active subcarriers to be used based on at least the indication of the quantity of subcarriers. The base station may transmit an indication of the number of active subcarriers to the UE. The UE may process one or more received IM downlink signals based on the quantity of subcarriers.
