Abstract
A method and apparatus for configuring Power Headroom Report (PHR) of a User Equipment (UE) efficiently in a mobile communication system supporting carrier aggregation are provided. The method includes generating a header including a LCID for identifying extended PHR and L indicating a length of the extended PHR, and inserting Power Headrooms (PHs) of multiple activated carriers into the extended PHR of one of the carriers.
Claims16
A method by a terminal in a mobile communication system, the method comprising:
- generating a MAC PDU including a header and an extended power headroom report (PHR), the header including a sub-header including a logical channel identifier (LCID) for identifying the extended PHR and length information on a length of the extended PHR, the extended PHR including information on power headrooms (PHs) of activated serving cells;
- and
- transmitting the MAC PDU to a base station,
- wherein, if simultaneous transmission of PUCCH and PUSCH is configured, the extended PHR includes a type II PH and a type I PH of a primary serving cell of the activated serving cells, and
- wherein the type I PH is included after the type II PH in the extended PHR.
A terminal in a mobile communication system, the terminal comprising:
- a controller configured to generate a MAC PDU including a header and an extended power headroom report (PHR), the header including a sub-header including a logical channel identifier (LCID) for identifying the extended PHR and length information on a length of the extended PHR, the extended PHR including information on power headrooms (PHs) of activated serving cells;
- and
- a transmitter configured to transmit the MAC PDU to a base station,
- wherein, if simultaneous transmission of PUCCH and PUSCH is configured, the extended PHR includes a type II PH and a type I PH of a primary serving cell of the activated serving cells, and
- wherein the type I PH is included after the type II PH in the extended PHR.
A method by a base station in a mobile communication system, the method comprising:
- receiving a MAC PDU including a header and an extended power headroom report (PHR), the header including a sub-header including a logical channel identifier (LCID) for identifying the extended PHR and length information on a length of the extended PHR, the extended PHR including information of power headrooms (PHs) of activated serving cells;
- and
- identifying PHs of the activated serving cells included in the extended PHR,
- wherein, if simultaneous transmission of PUCCH and PUSCH is configured, the extended PHR includes a type II PH and a type I PH of a primary serving cell of the activated serving cells, and
- wherein the type I PH is included after the type II PH in the extended PHR.
A base station in a mobile communication system, the base station comprising:
- a receiver configured to receive a MAC PDU including a header and an extended power headroom report (PHR), the header including a sub-header including a logical channel identifier (LCID) for identifying the extended PHR and length information on a length of the extended PHR, the extended PHR including information of power headrooms (PHs) of activated serving cells;
- and
- a controller configured to identify PHs of the activated serving cells included in the extended PHR,
- wherein if simultaneous transmission of PUCCH and PUSCH is configured, the extended PHR includes a type II PH and a type I PH of a primary serving cell of the activated serving cells, and
- wherein the type I PH is included after the type II PH in the extended PHR.
