Abstract
To transmit resource allocation information on a plurality of radio resources to a terminal, a resource allocation device expresses a radio resource that is differently allocated from before the resource allocation information is transmitted among the plurality of radio resources in a radio resource pattern sequence, generates resource allocation information on the plurality of radio resources based on the radio resource pattern sequence, and transmits the radio resource pattern sequence and the resource allocation information, or a compressed pattern sequence corresponding to the radio resource pattern sequence and the resource allocation information, to the terminal through a frame.
Claims8
A method for transmitting resource allocation information on a plurality of radio resources to a terminal, the method comprising:
- generating a pattern sequence that includes patterns corresponding to a plurality of radio resources;
- determining a compression unit length and dividing the first pattern sequence into a plurality of compression units based on the compression unit length;
- generating a compression indicator sequence that indicates a compression possibility for each group of the pattern sequence;
- generating a compressed pattern sequence based on the compression indicator sequence;
- generating resource allocation information on the plurality of radio resources, the resource allocation information based on the pattern sequence;
- and
- transmitting the compression unit length, the compression indicator sequence, the compressed pattern sequence, and the resource allocation information to the terminal,
- wherein the generating of the compressed pattern sequence includes:
- when a group can be compressed, expressing a compression pattern for the corresponding group in the compressed pattern sequence;
- and
- when a group cannot be compressed, expressing original patterns included in the corresponding group in the compressed pattern sequence.
A method for informing a terminal of radio resource allocation by using a pattern sequence including a plurality of radio resources, the method comprising:
- determining a compression unit length;
- dividing the pattern sequence into a plurality of compression units based on the compression unit length, determining a compression possibility for the plurality of compression units, and expressing the compression possibility in a compression indicator sequence;
- and
- expressing a compressed sequence in a compressed pattern sequence when compression can be performed according to the compression possibility, and expressing an original sequence in the compressed pattern sequence when the compression cannot be performed.
