A method executed by an enhanced node B (eNB), comprising: transmitting a discontinuous reception (DRX) configuration to a user equipment (UE), the DRX configuration indicating an on-duration, the on-duration corresponding to a time interval where the UE receives a downlink control channel; transmitting a precoding matrix index (PMI) resource configuration to a user equipment (UE), the resource configuration indicating a periodic PMI reporting resource; transmitting data to the UE; determining that the data was not received successfully by the UE; determining a time period for potential retransmissions; and receiving PMI using the PMI reporting resource until the determined time period ends. |
