Abstract
A method and an apparatus for efficiently transmitting or reporting a Power Headroom Report (PHR) of a User Equipment (UE) are provided. The method of transmitting the PHR of the UE in a mobile communication system includes configuring an extended PHR including an indicator corresponding to a variation factor of a maximum transmission power of the UE, and transmitting the extended PHR from the UE to a Base Station (BS). The BS may be notified of a maximum transmission power of the UE and a variation factor corresponding to the maximum transmission power in order to enable efficient scheduling.
Claims19
A method of transmitting a power headroom port (PHR) of a User Equipment (UE) in a mobile communication system, the method comprising:
- determining a maximum transmission power according to a parameter associated with power management;
- generating an extended PHR including the determined maximum transmission power and an indicator indicating whether the UE applies power back-off due to power management;
- and
- transmitting the extended PHR to a Base Station (BS),
- wherein the indicator has a length of 1 bit, and
- wherein the indicator has a bit value of 1 if the determined maximum transmission power is different from a maximum power transmission not applying power back-off due to power management.
An apparatus for transmitting a Power Headroom Report (PHR) of a User Equipment (UE) in a mobile communication system, the apparatus comprising:
- a controller configured to determine a maximum transmission power according to a parameter associated with power management, and to generate an extended PHR including the determined maximum transmission power and an indicator indicating whether the UE applies power back-off due to power management;
- and
- a transceiver configured to transmit the extended PHR to a Base Station (BS),
- wherein the indicator has a length of 1 bit, and
- wherein the indicator has a bit value of 1 if the determined maximum transmission power is different from a maximum power transmission not applying power back-off due to power management.
An apparatus for receiving a Power Headroom Report (PHR) of a Base Station (BS) in a mobile communication system, the apparatus comprising:
- a controller configured to generate control information including information corresponding to a configuration of an extended PHR;
- and
- a transceiver configured to transmit the control information and to receive the extended PHR from the UE,
- wherein the extended PHR includes an indicator indicating whether a maximum transmission power of the UE determined according to a parameter associated with power management is different from a maximum power transmission not applying power back-off due to power management,
- wherein the indicator has a length of 1 bit, and
- wherein the indicator has a bit value of 1 if the determined maximum transmission power is different from the maximum power transmission corresponding to the UE not applying power back-off due to power management.
A method of receiving a Power Headroom Report (PHR) at a Base Station (BS) in a mobile communication system, the method comprising:
- transmitting control information including information corresponding to a configuration of an extended PHR to a User Equipment (UE);
- and
- receiving the extended PHR from the UE,
- wherein the extended PHR includes an indicator indicating whether a maximum transmission power of the UE determined according to a parameter associated with power management is different from a maximum power transmission not applying power back-off due to power management;
- wherein the indicator has a length of 1 bit;
- and
- wherein the indicator has a bit value of 1 if the determined maximum transmission power is different from the maximum power transmission corresponding to the UE not applying power back-off due to power management.
