Abstract: Methods and apparatus are provided for reporting a Power Headroom (PH) of a User Equipment (UE) in a wireless communication system having a plurality of aggregated uplink carriers. A method includes receiving a configuration message to configure at least one uplink carrier; triggering a power headroom report (PHR) for a first uplink carrier if a predetermined event occurs; detecting an allocation of an uplink transmission resource for the PHR; identifying whether the first uplink carrier for which a power headroom (PH) is to be determined is different from a second carrier to which the uplink transmission resource is allocated; determining the PH based on a first pathloss associated with the first uplink carrier, if the first uplink carrier is different from the second carrier; and transmitting the PHR generated based the determined PH.

Abstract: An apparatus and a method are provided for receiving data in a communication system. Information is received representative of a number of processes of a persistent resource allocation and a persistent resource allocation interval. Data is received in a new transmission based on the received information. A HARQ process ID is calculated using the number of processes of the persistent resource allocation, the persistent resource allocation interval, and time information. Control information including the HARQ process ID is received. Data is received in a retransmission, based on the control information including the HARQ process ID. The data received in the new transmission and the data received in the retransmission are combined. The combined data is decoded.
