1. A method for a User Equipment (UE) configured to transmit data to a base station in subframes of a Time Division Duplex system, wherein a predetermined number of symbol intervals is utilized in a normal subframe, the method comprising:
determining that fewer symbol intervals will be utilized in an uplink subframe than in the normal subframe based on an uplink grant message scheduling the uplink subframe; and
in response to said determining, transmitting the uplink subframe by not transmitting in one or more symbol intervals at the beginning of the subframe interval for the uplink subframe and transmitting in symbol intervals of the remainder of the subframe interval.
