  • Feedback transmissions using uplink shared channel
    Patent number: 11240839
    Abstract: Methods, systems, and devices for wireless communications provide for feedback transmissions using an uplink shared channel. A user equipment (UE) may transmit feedback to a base station using physical uplink shared channel (PUSCH) resources. The base station may transmit an uplink grant to the UE indicating a set of resources for uplink data transmissions. The base station may subsequently transmit a downlink grant for the UE. Based on monitoring resources indicated by the downlink grant, the UE may generate feedback indicating the success of receiving or decoding the PDSCH transmission. The UE may transmit the feedback to the base station on the PUSCH resources. In some cases, the UE may transmit both the feedback for the PDSCH transmission received after the uplink grant and for a second PDSCH transmission received prior to the uplink grant using PUSCH resources.
