Patent ID: 10334581

Abstract:
A received first DCI comprises: a first trigger field (indicating that the first DCI is triggered in response to a second DCI comprising a second trigger), a validation field (indicating a validation duration for receiving the second DCI validating the first DCI), a hybrid retransmission request (HARQ) identifier field, and a new data identifier (NDI) field. TBs are created in response to the first DCI. In response to monitoring not detecting the second DCI: the first DCI is invalidated and transmission of TBs dropped; the HARQ process ID and the NDI are stored; and the first TBs are stored in a HARQ buffer. A third DCI indicating a same value of the HARQ process ID is received. Uplink signals are transmitted in response to the third DCI. The stored NDI are employed to determine an adaptive-retransmission of the TBs or a new transmission of second TBs.
