Abstract

The invention relates to a system, method, and apparatus for using acknowledgment or negative acknowledgment (ACK-NACK) packets when a user device (UE) ACK-NACK is packetized across multiple physical downlink shared channels (PDSCH) associated with PDSCH authorization. The Downlink Assignment Indicator (DAI) and total DAI can be used to monitor the PDSCH assignments received at the UE. The UE can detect missing PDSCHs and report ACK-NACKs for missing PDSCHs based on the DAI and total DAI counters. The base station (BS) can transmit PDSCH assignments associated with multiple PDSCHs to the UB. The BS can receive, from the UE, ACK-NACKs for multiple PDSCHs associated with the assigned PDSCH assignment. Specifically, invention refers to methods and devices for wireless communication.
