Mobile station, base station, and communication control method

Abstract

A mobile station which configures a plurality of component carriers to communicate with a base station includes a transmission unit configured to transmit to the base station a terminal capability associated with non-gap measurement indicating whether the mobile station is capable of performing inter-frequency measurement using a radio frequency (RF) chain which is not used for a component carrier; a reception unit configured to receive whether to allow the non-gap measurement from the base station; and a communication control unit configured to control communication according to a gap pattern of using a portion of an inter-frequency measurement duration for data communication, when the non-gap measurement is allowed.

1 . A mobile station which configures a plurality of component carriers to communicate with a base station, comprising:
 a transmission unit configured to transmit to the base station a terminal capability associated with non-gap measurement indicating whether the mobile station is capable of performing inter-frequency measurement using a radio frequency (RF) chain which is not used for a component carrier;   a reception unit configured to receive whether to allow the non-gap measurement from the base station; and   a communication control unit configured to control communication according to a gap pattern of using a portion of an inter-frequency measurement duration for data communication, when the non-gap measurement is allowed.   
     
     
         2 . The mobile station as claimed in  claim 1 , wherein the gap pattern is a gap pattern according to which data are not allocated to a first subframe and a last subframe in the inter-frequency measurement duration and the other subframes are used for data communication. 
     
     
         3 . The mobile station as claimed in  claim 1 , wherein the transmission unit transmits the terminal capability associated with the non-gap measurement for each combination of the component carriers. 
     
     
         4 . The mobile station as claimed in  claim 2 , wherein the transmission unit transmits the terminal capability associated with the non-gap measurement for each combination of the component carriers. 
     
     
         5 . A base station which configures a plurality of component carriers to communicate with a mobile station, comprising:
 a reception unit configured to receive from the mobile station a terminal capability associated with non-gap measurement indicating whether the mobile station is capable of performing inter-frequency measurement using a radio frequency (RF) chain which is not used for a component carrier;   a transmission unit configured to transmit whether to allow the non-gap measurement to the mobile station; and   a communication control unit configured to control communication according to a gap pattern of using a portion of an inter-frequency measurement duration for data communication, when the non-gap measurement is allowed.   
     
     
         6 . A communication control method in a mobile station which configures a plurality of component carriers to communicate with a base station, comprising the steps of:
 transmitting to the base station a terminal capability associated with non-gap measurement indicating whether the mobile station is capable of performing inter-frequency measurement using a radio frequency (RF) chain which is not used for a component carrier;   receiving whether to allow the non-gap measurement from the base station; and   controlling communication according to a gap pattern of using a portion of an inter-frequency measurement duration for data communication, when the non-gap measurement is allowed.
