Radio communication apparatus

1. An access network (AN) controlled by a communication control apparatus and communicating with an access terminal (AT), comprising:

the AN receives control information via a line interface, including information for allocating communication information from the communication control apparatus, and

the AN transmits transmission cycle information via a radio transceiver, for transmitting the communication information in a predetermined transmission cycle to the AT and allocates the communication information via a controller, in the predetermined transmission cycle based on the control information received from the communication control apparatus to send the communication information to the AT,

wherein, if the AN needs not to transmit any of plural pieces of the communication information to the AT, the AN pads a period allocated for the piece of the communication information not to be transmitted with the communication information which is allocated in a next transmission cycle.

2. An access network (AN) controlled by a communication control apparatus and communicating with a plurality of access terminals (AT), comprising:

the AN receives control information via a line interface, including information for multiplexing communication information from the communication control apparatus, and

the AN transmits transmission cycle information via a radio interface, for transmitting the communication information in a predetermined transmission cycle to the ATs and multiplexes the communication information via a controller, in the predetermined transmission cycle based on the control information received from the communication control apparatus to send it to the ATs,

wherein, if the AN needs not to transmit any of plural pieces of the communication information to the ATs, the AN pads a period allocated for the piece of the communication information not to be transmitted with the communication information which is allocated in a next transmission cycle.

3. A radio communication method performed by an access network (AN) wirelessly communicating with an access terminal (AT) and a communication control apparatus controlling the AN, comprising:

sending, by the communication control apparatus, transmission cycle information and control information to the AN, the transmission cycle information being for transmitting communication information to the AT in a predetermined transmission cycle and the control information including information for allocating the communication information;

sending, by the AN, the transmission cycle information received from the communication control apparatus to the AT;

allocating, by the AN, the communication information based on the control information received from the communication control apparatus and sends it in the predetermined transmission cycle to the AT; and

calculating, by the communication control apparatus, a transmission slot number necessary for transmitting the communication information in the predetermined transmission cycle based on a physical data rate and an application data rate corresponding to the communication information included in a transmission request from the AT to determine a transmission timing indicating a period in the predetermined cycle allocated for the communication information.

4. A radio communication method performed by an access network (AN) wirelessly communicating with an access terminal (AT) and a communication control apparatus controlling the AN, comprising:

sending, by the communication control apparatus, transmission cycle information and control information to the AN, the transmission cycle information being for transmitting communication information to the AT in a predetermined transmission cycle and the control information including information for allocating the communication information;

sending, by the AN, the transmission cycle information received from the communication control apparatus to the AT;

allocating, by the AN, the communication information based on the control information received from the communication control apparatus and sends it in the predetermined transmission cycle to the AT; and

if the AN needs not to transmit any of plural pieces of the communication information to the AT, padding, by the AN, a period allocated for the piece of the communication information not to be transmitted with the communication information which is allocated in a next transmission cycle.

5. A radio communication method performed by an access network (AN) for wirelessly communicating with a plurality of access terminals (ATs) and a communication control apparatus controlling the AN, comprising:

sending, by the communication control apparatus, transmission cycle information and control information to the AN, the transmission cycle information being for transmitting communication information to the ATs in a predetermined transmission cycle and the control information including information for multiplexing the communication information;

sending, by the AN, the transmission cycle information received from the communication control apparatus to the ATs;

multiplexing, by the AN, the communication information in the predetermined transmission cycle based on the control information received from the communication control apparatus to send it to the ATs; and

calculating, by the communication control apparatus, a transmission slot number necessary for transmitting the communication information in the predetermined transmission cycle based on a physical data rate and an application data rate corresponding to the communication information included in a transmission request from an AT of the ATs to determine a transmission timing indicating a period in the predetermined cycle allocated for the communication information.

6. A radio communication method performed by an access network (AN) for wirelessly communicating with a plurality of access terminals (ATs) and a communication control apparatus controlling the AN, comprising:
