Abstract
A multi-band scheduling method determines frequency bands for each of a plurality of frames existing in a single session queue from among a plurality of frequency bands based on data characteristics of each of the plurality of frames. In particular, the multi-band scheduling method may assign a frame with a high significance to a frequency band having a superior channel state, thereby increasing communication reliability. Also, a broadcasting service system may use the multi-band scheduling method to effectively provide the broadcasting services.
Claims19
A multi-band scheduling method comprising:
- designating at least two frequency bands;
- predicting at least one user's channel state at each of the at least two frequency bands;
- and
- determining a frequency band for each of a plurality of frames existing in each of at least one session queue from among the at least two frequency bands based on the at least one user's channel state at each of the at least two frequency bands and data characteristics of each of the plurality of frames.
A multi-band scheduling method for broadcasting services, comprising:
- designating at least two frequency bands for broadcasting services;
- and
- determining a frequency band for each of a plurality of frames included in a broadcasting data stream from among the at least two frequency bands based on characteristics of each of the plurality of frames.
A method of receiving broadcasting services using multiple frequency bands, the method comprising:
- receiving scheduling result information from a scheduler;
- ascertaining a frequency band for each of a plurality of frames included in a broadcasting data stream based on the scheduling result information from the scheduler;
- and
- decoding a plurality of frames received from a transmitter using an ascertained result,
- wherein the scheduler determines a frequency band for each of the plurality of frames from among the at least two frequency bands based on characteristics of each of the plurality of frames included in the broadcasting data stream.
