Abstract: Aspects described herein relate receiving a signal having a waveform including, within a symbol, resource elements for a physical downlink shared channel (PDSCH) and separate resource elements for multiple pilots to enable phase tracking, estimating, based on the multiple pilots, a channel response of the PDSCH, and removing, from the signal, a phase noise computed based on the channel response estimated for the PDSCH.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for data aided receivers for URLLC. With more specificity, a UE may encode and modulate at least one of control information or data from a first code block received through a first channel from a base station to obtain an encoded and modulated reference first code block. A comparison between the reference first code block and the first code block may be performed by the UE to estimate a second channel for receiving a second code block from the base station. After receiving the second code block from the base station, the UE may demodulate and decode the second code block based on the second channel that was estimated via the comparison of the reference first code block to the first code block.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for a DPD training procedure. A base station may transmit, for a plurality of iterations, a signal to at least one UE through a plurality of transmit chains and with application of DPD. The signal transmitted for each iteration may be transmitted with a BW that extends over a plurality of subcarriers and includes pilots extending over a BW subset that increases in subcarrier size for each iteration. The base station may receive, for each iteration, feedback from the at least one UE based on the transmitted signal and apply DPD to each of the plurality of transmit chains based on the feedback. Accordingly, the base station may transmit to one or more UEs through the plurality of transmit chains and with application of the DPD pilot signals that extend over the entire BW.
