Patent ID: 7408904

Claim:
A method for supporting adaptive modulation and coding (AM&C) and hybrid automatic repeat request (H-ARQ) functions, the method comprising: receiving at a wireless transmit/receive unit (WTRU) a signal indicating a need for AM&C and H-ARQ control signaling; dynamically allocating at least one AM&C and H-ARQ signaling transport channel by informing a transport format selection process of the need for AM&C and H-ARQ control signaling; selecting a transport format set for required transmission time intervals (TTIs) of the transport channel which assign transport format combinations (TFCs) to establish the AM&C and H-ARQ signaling transport channel; and aligning control channel TTIs with AM&C and H-ARQ transmissions on the AM&C and H-ARQ signaling transport channel such that each control channel TTI begins and ends at the same time as a corresponding AM&C and H-ARQ transmission.
