Abstract
[Object] To make it possible to reduce the load related to MBMS for the terminal device supporting carrier aggregation. [Solution] There is provided an apparatus including an acquisition unit configured to acquire specific information used to specify a physical multicast channel (PMCH) of two or more component carriers including a first component carrier, and a control unit configured to control transmission of the specific information on the first component carrier.
Claims17
An apparatus comprising:
- circuitry configured to
- acquire scheduling information of a MCCH (multicast control channel) for two or more component carriers including a first component carrier;
- acquire MBSFN (multimedia broadcast multicast services (MBMS) over a single frequency network) area configuration information for the two or more component carriers;
- control transmission of a predetermined system information block comprising the scheduling information for the two or more component carriers on the first component carrier to a terminal device, the scheduling information being used by the terminal device to specify the MCCH and acquire the MBSFN area configuration information using the specified MCCH;
- and
- control transmission of the MBSFN area configuration information on the MCCH of the first component carrier specified by the scheduling information to the terminal device, the MBSFN area configuration information being used by the terminal device to specify a PMCH (physical multicast channel) of the two or more component carriers to which desired MBMS session is mapped and acquire the desired MBMS session using the specified PMCH.

A method comprising:
- acquiring scheduling information of a MCCH (multicast control channel) for two or more component carriers including a first component carrier;
- acquiring MBSFN (multimedia broadcast multicast services (MBMS) over a single frequency network) area configuration information for the two or more component carriers;
- controlling, using circuitry, transmission of a predetermined system information block comprising the scheduling information for the two or more component carriers on the first component carrier to a terminal device, the scheduling information being used by the terminal device to specify the MCCH and acquire the MBSFN area configuration information using the specified MCCH;
- and
- controlling, using the circuitry, transmission of the MBSFN area configuration information on the MCCH of the first component carrier specified by the scheduling information to the terminal device, the MBSFN area configuration information being used by the terminal device to specify a PMCH (physical multicast channel) of the two or more component carriers to which desired MBMS session is mapped and acquire the desired MBMS session using the specified PMCH.

An apparatus comprising:
- circuitry configured to
- acquire scheduling information of a MCCH (multicast control channel) for two or more component carriers including a first component carrier, the scheduling information being transmitted within a predetermined system information block on the first component carrier by a base station;
- specify the MCCH based on the acquired scheduling information;
- acquire MBSFN (multimedia broadcast multicast services (MBMS) over a single frequency network) area configuration information for the two or more component carriers using the specified MCCH, the MBSFN area configuration information being transmitted on the MCCH of the first component carrier specified by the scheduling information by the base station;
- specify a PMCH (physical multicast channel) of the two or more component carriers to which desired MBMS session is mapped;
- and
- acquire the desired MBMS session using the specified PMCH.
