Abstract
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.
Claims8
A radio transmitting apparatus comprising:
- an allocating section that performs frequency scheduling for a mobile station apparatus and allocates a resource block comprising a control unit in frequency scheduling, to the mobile station apparatus;
- a grouping section that groups a plurality of mobile station apparatuses that satisfy a predetermined requirement as low rate user equipment that receives low rate data, and assigns a group identity to the grouped low rate user equipment;
- a shared control channel generating section that generates a shared control channel including the group identity;
- a control information generating section that generates control information showing allocation information of a resource block allocated to the low rate user equipment;
- a multiplexing section that multiplexes the shared control channel, data and the control information, and multiplexes the control information on a data field of the resource block to which the low rate data is allocated;
- and
- a transmitting section that transmits a multiplexed signal.
A radio transmission method comprising:
- an allocating step of performing frequency scheduling for a mobile station apparatus and allocating a resource block comprising a control unit of frequency scheduling, to the mobile station apparatus;
- a grouping step of grouping a plurality of mobile station apparatuses that satisfy a predetermined requirement as low rate user equipment that receives low rate data, and assigning a group identity to the grouped low rate user equipment;
- and
- a multiplexing step of multiplexing a shared control channel including the group identity, control information showing allocation information of a resource block allocated to the low rate user equipment and data, and multiplexing the control information on a data field of the resource block to which the low rate data is allocated.
