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.

Claim
1. A method by a terminal in a wireless communication system, the method comprising:
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.
2. The method of claim 1, further comprising determining the PH based on a second pathloss associated with the second uplink carrier, if the first uplink carrier is not different from the second carrier.
3. The method of claim 1, further comprising:
after receiving the configuration message, receiving a control message to activate the first uplink carrier;
determining whether a predetermined time has elapsed after receiving the control message; and
triggering the PHR, prior to receiving a message associated with the allocation of the uplink transmission resource, if the predetermined time has elapsed,
wherein the received message is associated with the first uplink carrier.
4. The method of claim 1, further comprising:
determining whether the message is received when the PHR is triggered; and
if the message is received, calculating the PH of the PHR, generating the PHR using the calculated PH, and transmitting the generated PHR.
5. The method of claim 1, further comprising, if the message is not received, continuing to await the allocation of an uplink transmission resource until the message is received.
6. A terminal in a wireless communication system, the terminal comprising:
a transceiver configured to transmit and receive a signal; and
a controller configured to
receive a configuration message to configure at least one uplink carrier,
trigger a power headroom report (PHR) for a first uplink carrier if a predetermined event occurs,
detect an allocation of an uplink transmission resource for the PHR,
identify 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,
determine 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
transmit the PHR generated based the determined PH.
7. The terminal of claim 6, wherein the controller is further configured to determine the PH based on a second pathloss associated with the second uplink carrier, if the first uplink carrier is not different from the second carrier.
8. The terminal of claim 6, wherein the controller is further configured to
receive a control message to activate the first uplink carrier, after receiving the configuration message,
determine whether a predetermined time has elapsed after receiving the control message, and
trigger the PHR, prior to receiving a message associated with the allocation of the uplink transmission resource, if the predetermined time has elapsed,
wherein the received message is associated with the first uplink carrier.
9. The terminal of claim 6, wherein the controller is further configured to
determine whether the message is received when the PHR is triggered,
calculate the PH of the PHR if the message is received,
generate the PHR using the calculated PH, and
transmit the generated PHR.
10. The terminal of claim 6, wherein the controller is further configured to, if the message is not received, continue to await the allocation of an uplink transmission resource, until the message is received.
