  • Publication number: 20220150029
    Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for reducing the overhead associated with reporting feedback, such as hybrid automatic repeat request (HARQ) feedback. A user equipment (UE) may receive a configuration message from a base station indicating that the UE is to request resources for transmitting negative acknowledgment (NACK) feedback for a downlink transmission. If the UE fails to receive or decode the downlink transmission, the UE may request resources from the base station on which to transmit the NACK feedback for the downlink transmission. Because the UE may be configured to request resources on which to transmit the NACK feedback, the UE may avoid transmitting HARQ feedback for every downlink transmission from the base station. Thus, the base station may avoid allocating resources for HARQ feedback from the UE for every downlink transmission, and the overhead of reporting HARQ feedback is reduced.

  • Publication number: 20220150941
    Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for improving the reliability of downlink transmissions from a base station to a user equipment (UE). The UE may determine one or more preferred configurations for the base station to use to transmit multiple downlink transmissions to the UE, and the UE may transmit a recommendation of the preferred configuration(s) to the base station. The base station may then determine configurations to use for the multiple downlink transmissions based on the recommendation received from the UE, and the base station may transmit the downlink transmissions to the UE using the determined configurations. Because the UE may provide the recommendation of the preferred configuration(s) to the base station, the configurations used by the base station for the multiple downlink transmissions may be selected specifically for the UE. Thus, the reliability of the downlink transmissions may improve.
