Abstract

The disclosed mobile communication method involves: a process (A) wherein a mobile station (UE) receives an uplink grant, which permits the mobile station (UE) to transmit an uplink data signal in uplink component carrier (ULCC) #1, via a physical downlink control channel (PDCCH) in downlink component carrier (DLCC) #2; and a process (B) wherein the mobile station (UE) cancels the uplink grant if the transmission power of ULCC #1 is being controlled on the basis of path loss that is assumed from the inactive state of DLCC #1.

Claims (4)

  1. [Claim 1]
    A mobile communication method, in which a mobile station communicates with a radio base station by using a plurality of downlink carriers and a plurality of uplink carriers, each of which has a different carrier frequency, the method comprising:
    a step A of receiving, by the mobile station, a scheduling signal for permitting the mobile station to transmit an uplink data signal in a predetermined uplink carrier through a physical downlink control channel in a first downlink carrier; and a step B of discarding, by the mobile station, the scheduling signal when transmission power of the predetermined uplink carrier is controlled on the basis of path loss estimated from a second downlink carrier in a deactive state.
  2. [Claim 2]
    The mobile communication method according to claim 1, wherein, in the step A, the mobile station receives a carrier indicator indicating the predetermined uplink carrier together with the scheduling signal.
  3. [Claim 3]
    The mobile communication method according to claim 1, further comprising: a step of notifying, by the radio base station, the mobile station of information for correlating the predetermined uplink carrier with the first downlink carrier by broadcast information.
  4. [Claim 4]
    A mobile station configured to be capable of communicating with a radio base station by using a plurality of downlink carriers and a plurality of uplink carriers, each of which has a different carrier frequency, the mobile station comprising:
    a reception unit configured to receive a scheduling signal for permitting the mobile station to transmit an uplink data signal in a predetermined uplink carrier through a physical downlink control channel in a first downlink carrier, wherein when transmission power of the predetermined uplink carrier is controlled on the basis of path loss estimated from a second downlink carrier in a deactive state, the reception unit is configured to discard the scheduling signal.
