Claim of US Patent No. 9,137,779

1. A Multimedia Broadcast Multicast Service (MBMS) dedicated carrier configuration method, comprising:
assigning MBMS dedicated carrier bundling information to a downlink timeslot of a radio frame of one MBMS dedicated carrier
in a cell; and

combining a downlink pilot timeslot, an uplink pilot timeslot, and a chip guard period between the downlink and the uplink
in the MBMS dedicated carrier frame as a short timeslot corresponding to the downlink timeslot used to control information
transmission, wherein the dedicated carrier bundling information includes MBMS system information and MBMS control information
of all dedicated carriers that are bundled to transmit MBMS services in the cell, wherein the downlink timeslot, assigned
the MBMS system information and the MBMS control information of all dedicated carriers that are bundled to transmit MBMS services
in the cell, comprises a MBMS broadcast control channel BCCH and a MBMS point-to-multipoint control channel MCCH, wherein
the MBMS system information is carried on the BCCH and mapped to a primary common control physical channel PCCPCH via a broadcast
channel BCH and the MBMS control information is carried on the MCCH and mapped to a secondary common control physical channel
SCCPCH via a forward access channel FACH.
