RADIO TRANSMISSION DEVICE AND RADIO TRANSMISSION METHOD

摘要

Disclosed are a radio transmission device and a radio transmission method capable of containing a plenty of mobile stations for receiving low-rate data and avoiding lowering a system throughput. A group ID assigning unit (108) groups UE receiving low-rate data and assigns a frequency by using the group ID. An SCCH processing unit (109) generates an SCCH containing the group ID. A low-rate control information processing unit (113) generates low-rate control information indicating a timing slot to which a low-rate UE has been assigned. A multiplexing unit (117) multiplies low-rate control information on RB to which low-rate data is assigned when multiplexing a pilot channel, SCCH, and data.
