Wireless communication system, mobile station device, and wireless reception method

摘要

A base station device includes: a control signal generator that generates a signal of control data including items corresponding to the type of sub-frames to be allocated; a scheduling information signal generator that generates a signal of scheduling information indicating a sub-frame to be a first sub-frame among sub-frames specified by first-type sub-frame candidate information; and a multiplexer that allocates the signal of the control data to the first-type and second-type sub-frames, and allocates the signal of the scheduling information to the first-type sub-frame. A mobile station device includes: a frame-type determining unit that determines the type of each of received sub-frames based on the first-type sub-frame candidate information and the scheduling information; and a control data detector that detects, for each sub-frame, the control data including the items corresponding to the type indicated by the result of the determination by the frame-type determining unit. Accordingly, the processing load on reception of control data is reduced.

1. A mobile station device configured to communicate with a base station device, the mobile station device comprising:
a reception processor configured to:
receive a MBSFN (Multicast/Broadcast over Single Frequency Network) sub-frame and a unicast sub-frame from the base station device, the MBSFN sub-frame being used for receiving MBMS (Multimedia Broadcast/Multicast Service) data using a multicast channel and receiving unicast data using a downlink shared data channel, and the unicast sub-frame being used for receiving the unicast data using the downlink shared data channel,receive from the base station device using the downlink shared data channel, sub-frame specifying information that specifies a plurality of sub-frames reserved as the MBSFN sub-frames, andreceive from the base station device using the multicast channel, scheduling information that specifies a plurality of sub-frames for transmitting the MBMS data from among the plurality of the sub-frames reserved as the MBSFN sub-frames, and a decoding processor configured to:
attempt to decode downlink control information indicating radio resource assignment for the downlink shared data channel in one of the plurality of the sub-frames reserved as the MBSFN sub-frames, the one of the plurality of the sub-frames being different from a sub-frame for transmitting the MBMS data which is indicated based on the scheduling information and which is included in the plurality of sub-frames, anddecode the downlink shared data channel in the one of the plurality of the sub-frames reserved as the MBSFN sub-frames in a case that a downlink control channel including the downlink control information is detected in the one of the plurality of the sub-frames reserved as the MBSFN sub-frames, wherein the multicast channel, the downlink shared data channel and the downlink control channel are mapped to physical resources.
