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.
Claims20
A method for reporting power headroom by a terminal in a mobile communication system, the method comprising:
- receiving information indicating a first power headroom report (PHR) format;
- determining whether a PHR is triggered;
- and
- transmitting a maximum transmit power (PCMAX) and a power headroom (PH) associated with at least one activated carrier in the PHR using the first PHR format, the PH being obtained based on the PCMAX.
A terminal for reporting power headroom (PH) 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 power headroom report (PHR) format,
- determine whether PHR is triggered, and to
- transmit a maximum transmit power (PCMAX) and a power headroom (PH) associated with at least one activated carrier in the PHR using the first PHR format, the PH being obtained based on the PCMAX.
A base station for receiving a power headroom report (PHR) in a mobile communication system, the base station comprising:
- a transceiver configured to transmit and receive a signal;
- and
- a controller configured to:
- identify information indicating a first PHR format based on a number of activated uplink carriers for a terminal,
- transmit a control message comprising the information, and
- receive a maximum transmit power (PCMAX) and a power headroom (PH) associated with at least one activated uplink carrier for the terminal using the first PHR format, the PH being obtained based on the PCMAX.
A method for receiving a power headroom report (PHR) by a base station in a mobile communication system, the method comprising:
- identifying information indicating a first PHR format based on a number of activated uplink carriers for a terminal;
- transmitting a control message comprising the information;
- and
- receiving a maximum transmit power (PCMAX) and a power headroom (PH) associated with at least one activated uplink carrier for the terminal using the first PHR format, the PH being obtained based on the PCMAX.
