Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for mapping coding indices associated with a rateless coding scheme to respective sets of communication resources over which a transmitting device may perform transmissions of portions of a message corresponding to each of the coding indices. In some aspects, for example, different coding indices may correspond to different cumulative portions of the message and the transmitting device may transmit a first cumulative portion of the message corresponding to a first coding index over a first set of communication resources to which the first coding index is mapped. The transmitting device may signal an indication of such a resource mapping scheme to a receiving device and the receiving device may attempt to decode transmissions of one or more cumulative portions of the message using the indicated resource mapping scheme.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for signaling mechanisms associated with transmission puncturing schemes for rateless coding. In some aspects, a transmitting device may encode a message using a rateless code associated with a cumulative encoding of various portions of the message and may perform transmission puncturing to adapt a bit rate of related signal transmissions. The transmitting device may signal an indication of the transmission puncturing scheme, and potentially one or more modifications to the transmission puncturing scheme, to a receiving device via control signaling. The transmitting device may modify the transmission puncturing scheme in accordance with prioritizing retransmissions for some cumulative portions of the message ahead of other cumulative portions, such as by granting prioritized cumulative portions of the message relatively earlier transmission occasions in the transmission puncturing scheme.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may indicate, to a user equipment (UE), when it changes a power amplifier (PA) non-linearity model. The base station may transmit a set of parameters for the PA model, and a set of parameters for a non-linear equalizer function for the UE to use during a digital post-processing procedure (DPoD). The base station may indicate, to the UE, a lookup table, a vector of lookup tales, a set of kernels (e.g., from which the UE may estimate the coefficients of the PA model), or a set of both the kernels and the coefficients for the PA model. Similarly, for the non-linear equalizer function, the base station may indicate an explicit indication of the function, or may indicate a lookup table, or a kernels series (e.g., with or without corresponding coefficients).

Abstract: Methods, systems, and devices for wireless communications are described. Aspects of the present disclosure describe spatial precoding for inter symbol interference reduction in single carrier. Generally, the described techniques provide for one or more wireless devices (e.g., a user equipment (UE) and a network entity) to determine a weighted sum of several beams, each with a different delay, to form a spatial precoder that increases signal to interference noise ratios while improving signaling quality by diversifying the number of beams carrying subsequent messaging. The one or more wireless devices may determine complex gain values and delay parameters based on reference signals. The one or more wireless devices may utilize the complex gain values and delay parameters such that subsequent transmissions may be received coherently over multiple beams.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability message indicating a capability of the UE to perform bandwidth-limited envelope tracking or a capability of the UE to compensate for bandwidth-limited envelope tracking distortion. The UE may receive a request for the UE to activate bandwidth-limited envelope tracking or a request for the UE to compensate for bandwidth-limited envelope tracking distortion. In some examples, the UE may transmit an uplink message using a bandwidth-limited envelope tracking configuration. In other examples, the UE may receive a downlink message and use digital post distortion (DPoD) to correct bandwidth-limited envelope tracking distortions in the downlink message. Aspects of the present disclosure may enable the UE to use bandwidth-limited envelope tracking and DPoD for wideband signal transmissions, which may result in lower power consumption at the UE.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for flexible selection of a type of mapping to use for mapping code blocks to a set of resources for transmission. A user equipment (UE) may transmit assistance information to a base station to assist the base station in selecting from a set of mapping types available for code block mapping. The UE may then receive, from the base station, an indication of a selected mapping type for code block mapping based on the assistance information. The assistance information may include a recommendation of a mapping type or a metric of a channel that the base station may use to select the mapping type. Because the mapping type may be selected dynamically (e.g., “on the fly”), the UE and the base station may be able to adaptively exploit different types of diversity.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform both a channel estimation and a non-linearity estimation (e.g., a power amplifier (PA) model estimation) on a demodulation reference signal (DMRS) transmitted by a base station. For example, the DMRS may include two portions that correspond to two peak-to-average power ratio (PAPR) values. Low PAPR values may enable the UE to perform the channel estimation, and high PAPR values may enable the UE to perform the PA non-linearity estimation. Accordingly, a first portion of the DMRS may correspond to a lower PAPR value, and the second portion of the DMRS may correspond to a higher PAPR value. In some examples, the base station may signal different parameters for each portion of the DMRS to the UE, or the UE may use fixed values to receive each portion of the DMRS.

Abstract: Wireless communications systems and methods related to hybrid in-band same-frequency full-duplex (SFFD) and frequency-offset-frequency full-duplex (FD) wireless communication are provided. A user equipment (UE) transmits first data to a base station (BS) over a first frequency band while receiving second data from the BS the first frequency band responsive to a first pathloss between the UE and the BS satisfying a threshold for an SFFD operation. The UE transmits third data to the BS over a second frequency band while receiving fourth data from the BS over a third frequency band that is distinct from the second frequency band according to an offset-frequency FD operation responsive to a second pathloss between the UE and the BS failing to satisfying the threshold.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) and a base station implement reference signal modulation for conveying feedback information. In some examples, the UE may receive, from the base station, control signaling indicating to the UE to convey feedback information by modulating an uplink reference signal. The UE may receive, from the base station, a set of downlink messages. In some cases, the UE may transmit, to the base station, a set of uplink reference signals in response to receiving the downlink messages, where the set of uplink reference signals may be modulated by the UE to convey the feedback information. In some cases, the uplink reference signal may be a sounding reference signal (SRS) with embedded feedback information.

Abstract: Techniques for wireless communications are described. A demodulation reference signal generated using user information and a noncoherent modulation technique may be communicated between wireless devices. A data sequence may be extracted from the demodulation reference signal based on demodulating the demodulation reference signal using the noncoherent modulation technique and decoding the demodulation reference signal. The data sequence may be used to reconstruct a version of the demodulation reference signal used to descramble a received version of the demodulation reference signal. The descrambled demodulation reference signal may be used to estimate a data channel between a transmitting device and a receiving device.
