6 Claims

1. A method performed by a User Equipment (UE), the method comprising:

receiving, from a Base Station (BS), Downlink Control Information (DCI) on a Physical Downlink Control Channel (PDCCH), the DCI scheduling a reception of Downlink (DL) data on a Physical Downlink Shared Channel (PDSCH), the DCI including an indicator indicating a Hybrid Automatic Repeat reQuest (HARQ) process number;

receiving an RRC configuration including a first value indicating a number of a plurality of HARQ processes to be used for the reception of the DL data and a second value indicating how many of the plurality of HARQ processes do not need to have a corresponding HARQ feedback transmission; and

determining whether to transmit a HARQ feedback for the DL data according to whether the HARQ process number is within a specific range configured by the BS, wherein the specific range is determined based on a combination of the first value and the second value.
