wherein the overload condition information includes a back off time information for the plurality of the terminals.
2. The method of claim 1, wherein each RA response comprises uplink timing information, uplink allocation information, and temporary terminal identifier.
3. The method of claim 2, wherein the uplink allocation information indicates uplink resource to be used on the uplink transmission and further indicates modulation and coding scheme for the uplink resource.
4. The method of claim 1, wherein the RA response message includes:
the common information comprising the overload condition information;
first RA preamble indicator corresponding to a first terminal among the terminals;
second RA preamble indicator corresponding to a second terminal among the terminals;
first RA response corresponding to the first terminal; and
second RA response corresponding to the second terminal.
5. The method of claim 4, wherein the first RA response comprises first uplink timing information, first uplink allocation information, and first temporary terminal identifier corresponding to the first terminal and the second RA response comprises second uplink timing information, second uplink allocation information, and second temporary terminal identifier corresponding to the second terminal.
6. The method of claim 1, wherein the RA response message further includes preamble existence field indicating if additional RA preamble indicator exists or not.
7. A method for Random Access (RA) of a first terminal in a communication system, the method comprising:
transmitting an RA preamble to a base station; and
receiving an RA response message from the base station, wherein the RA response message includes: common information for the first terminal and second terminals attempting RA to the base station wherein the common information comprises overload condition information with respect to the RA of the first terminal and the second terminals;
first RA preamble indicator corresponding to the first terminal; a plurality of RA preamble indicators respectively corresponding to the second terminals;
first RA response corresponding to the first terminal; and a plurality of RA responses respectively corresponding to the second terminals, wherein the common information including the overload condition information in the RA response message is distinct from the plurality of RA preamble indicators and the plurality of RA responses, and the RA response message further includes an information discrimination field indicating that the overload condition information is included;
wherein the overload condition information includes a back off time information for the first terminal and the second terminals.
8. The method of claim 7, wherein the first RA response comprises uplink timing information, uplink allocation information, and temporary terminal identifier for the first terminal.
9. The method of claim 8, wherein the uplink allocation information indicates uplink resource to be used on the uplink transmission and further indicates modulation and coding scheme for the uplink resource.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
