Abstract
The present invention realtes to a resource allocation method of a base station. The method includes generating a packet data unit that includes a first field and a downlink control message, wherein the first field indicates whether unsolicited resource is to be allocated for an uplink control message, transmitting the generated packet data unit to the terminal, allocating resources for the uplink control message, and transmitting the allocated resources to the terminal.
Claims20
A method for allocating resources for an uplink control message at base station, the method comprising:
- generating a packet data unit that includes a first field and a downlink control message, wherein the first field indicates whether unsolicited resource is to be allocated for an uplink control message;
- transmitting the generated packet data unit to the terminal;
- allocating resources for the uplink control message;
- and
- transmitting the allocated resources to the terminal.
A method for transmitting an uplink control message at a terminal, the method comprising:
- receiving a packet data unit including a first field and a downlink control message, wherein the first field indicates whether or not a base station allocates unsolicited resource for the uplink control message;
- checking the first field when the uplink control message is generated;
- waiting unsolicited resource allocation to transmit the uplink control message for a first time when the first field indicates that the base station would allocate unsolicited resource for the uplink control message;
- and
- when the base station allocates resources for the uplink control message within the first time, transmitting the uplink control message using the allocated resources.
A method for transmitting a downlink control message at a base station, comprising:
- generating a packet data unit including a common header, an expended header related to unsolicited resource allocation, and a downlink control message;
- and
- transmitting the packet data unit to a terminal.
A hand-off method of a base station, comprising:
- receiving a hand-off request message from a terminal;
- transmitting a hand-off command message to the terminal, wherein the hand-off command message includes a first field indicates whether unsolicited resource is to be allocated for a hand-off indication message of the terminal;
- allocating uplink resources for the hand-off indication message;
- and
- receiving the hand-off indication message from the terminal through allocated resource.
