## Abstract

Methods and apparatus for dynamically allocating HARQ processes are described. A wireless transmit/receive unit (WTRU) includes a receive unit configured to receive signaling and a transmit unit. The transmit unit is configured to transmit uplink data sequentially using a first integer number of hybrid automatic repeat request (HARQ) processes during normal HARQ operation and transmit uplink data using a second integer number of HARQ processes that is less than the first number of HARQ processes in response to receiving the signaling.

## Claims
