Dynamic assignment of ACK resource in a wireless communication system

A method for wireless communication, comprising:

• mapping, according to a message format that is associated with both semi-persistent assignments that are valid for multiple transmissions of data and dynamic assignments that are valid for single transmissions of data, scheduling information for a semi-persistent assignment to a scheduling message intended for a user equipment (UE), wherein the message format comprises a new data indicator field that,
• for the dynamic assignments, carries information used in processing transmissions associated with the dynamic assignments, and
• for the semi-persistent assignments, is set to a designated value for validation of the semi-persistent assignments;
• mapping the new data indicator field to a designated value, wherein the designated value indicates that the scheduling message comprises a semi-persistent assignment;
• mapping an assignment of a first acknowledgement (ACK) resource to a transmit power control (TPC) command field of the scheduling message for the semi-persistent assignment;
• sending the scheduling message to the UE;
• sending the multiple transmissions of data to the UE according to the semi-persistent assignment;
• and
• receiving first ACK information on the first ACK resource.
