Abstract
An information format and apparatus used by a base station to make a scheduling decision when the base station allocates resource to a terminal in a mobile communication system are provided. Operations of a terminal to report a maximum transmission power accurately to the base station in a scheduling process are also provided. A method for calculating a maximum transmit power in a constant manner regardless of a channel status is also provided.
Claims15
A power headroom reporting method of a terminal in a mobile communication system, the method comprising:
- receiving information indicating a first PHR format;
- determining whether a Power Headroom Report (PHR) is triggered;
- transmitting a maximum transmit power (PCMAX) and a Power Headroom (PH) associated with at least one of activated carriers using the first PHR format, the PH being obtained based on the PCMAX.
A terminal for reporting power headroom in a mobile communication system, the terminal comprising:
- a transceiver for transmitting and receiving a signal;
- and
- a controller for controlling to receive information indicating a first PHR format, determine whether a Power Headroom Report (PHR) is triggered, and to transmit a maximum transmit power (PCMAX) and a Power Headroom (PH) associated with at least one of activated carriers using the first PHR format, the PH being obtained based on the PCMAX.
A base station for receiving a Power Headroon Report(PHR) in a mobile communication system, the base station comprising:
- a transceiver for transmitting and receiving a signal;
- and
- a controller for control to identify information indicating a first PHR format based on the number of activated uplink carriers for a terminal, transmit a control message comprising the information, receives a maximum transmit power (PCMAX) and a Power Headroom (PH) associated with at least one of activated carriers for the terminal using the first PHR format, the PH being obtained based on the PCMAX
