Abstract

Methods, systems, and devices for wireless communications are described. The techniques described herein relate to an early termination predictor report. A user equipment (UE) monitors for a first downlink signal from a network entity. The UE transmits a predictor report indicative of an early decoding termination prediction accuracy associated with decoding the first downlink signal by a decoder of the UE. The UE monitors, in response to transmitting the predictor report, for a second downlink signal from the network entity, the second downlink signal based at least in part on the predictor report.

Description

FIELD OF TECHNOLOGY The following relates to wireless communications, including an early termination predictor report. BACKGROUND Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple-access communications system may include one or more base stations, each supporting wireless communication for communication devices, which may be known as user equipment (UE). A UE may perform decoding operations on encoded downlink signals from the network entity to obtain information in the encoded downlink signals. In some examples, the UE may include a decoder to perform the decoding operations, and the decoder may predict decoding failures and terminate decoding operations early to reduce unnecessary utilization of computational resources of the decoder. However, in some examples, the prediction may be inaccurate, such that the decoding may have been successful and thus, was unnecessarily terminated. SUMMARY The described techniques relate to improved methods, systems, devices, and apparatuses that support an early termination predictor report. A user equipment (UE) may transmit a signal indicating an early termination predictor report (ETPR) to the network entity, where the ETPR indicates the accuracy of the early termination prediction. In some examples, the UE may transmit a signal indicating an ability to report the ETPR. The network entity may transmit a signal to the UE that indicates parameters for reporting the ETPR to the network entity, and the UE may estimate and send the ETPR in accordance with the parameters. The UE may transmit the signal indicating the ETPR (e.g., based on an accuracy threshold), which indicates the accuracy of the predictor or the early termination prediction. In some examples, the network entity may, in response to receiving the ETPR, optimize a power consumption and performance tradeoff at the UE, as well as signal a downlink shared channel with parameters that are updated based on the ETPR. The UE may estimate the early termination predictor accuracy again and send another ETPR when the power consumption and performance tradeoff is below a threshold tradeoff. In some examples, the UE may transmit a signal indicating a channel state feedback report, where the report indicates a configuration for the UE to optimize the accuracy of the predictor. A method for wireless communications by a UE is described. The method may include monitoring for a first downlink signal from a network entity, transmitting a predictor report indicative of an early decoding termination prediction accuracy associated with decoding the first downlink signal by a decoder of the UE, and monitoring, in response to transmitting the predictor report, for a second downlink signal from the network entity, the second downlink signal based on the predictor report. A UE for wireless communications is described. The UE may include one or more memories storing processor executable code, and one or more processors coupled with the one or more memories. The one or more processors may individually or collectively operable to execute the code to cause the UE to monitor for a first downlink signal from a network entity, transmit a predictor report indicative of an early decoding termination prediction accuracy associated with decoding the first downlink signal by a decoder of the UE, and monitor, in response to transmitting the predictor report, for a second downlink signal from the network entity, the second downlink signal based on the predictor report. Another UE for wireless communications is described. The UE may include means for monitoring for a first downlink signal from a network entity, means for transmitting a predictor report indicative of an early decoding termination prediction accuracy associated with decoding the first downlink signal by a decoder of the UE, and means for monitoring, in response to transmitting the predictor report, for a second downlink signal from the network entity, the second downlink signal based on the predictor report. A non-transitory computer-readable medium storing code for wireless communications is described. The code may include instructions executable by one or mor
