1. A method for controlling the timing of feedback transmissions from a receiving device by a transmitting device communicating over a communication link, wherein the communication link supports a retransmission scheme and wherein the method comprises:
transmitting a first feedback timing indicator (FTI) and data, wherein the first FTI indicates no specific subframe in which retransmission feedback is requested; and
transmitting a second FTI, wherein the second FTI indicates when retransmission feedback related to the data is requested.
