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.
Claims17
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
- scheduling each frame from a plurality of frames included in a single session queue to the at least two designated frequency bands, based on the at least one user's channel state at the at least two frequency bands and based on whether a frame comprises an infra frame (I-frame), a previous frame (P-frame), or a bidirectional frame (B-frame),
- wherein the scheduling is performed for a plurality of session queues, multiple frames in each session queue comprise different quality of service (QoS) requirements, and the multiple frames in each session queue are individually designated to the at least two frequency bands based on a quality of service requirement determined for each individual frame and based on differing qualities of the at least two frequency bands.
A multi-band scheduling method for broadcasting services, comprising:
- designating at least two frequency bands for broadcasting services;
- and
- scheduling a frequency band for each frame from a plurality of frames included in a single broadcasting data stream queue from among the at least two frequency bands based on whether the frame comprises an infra frame (I-frame), a previous frame (P-frame), or a bidirectional frame (B-frame),
- wherein the scheduling is performed for a plurality of session queues, multiple frames in each session queue comprise different quality of service (QoS) requirements, and the multiple frames in each session queue are individually designated to the at least two frequency bands based on a quality of service requirement determined for each individual frame and based on differing qualities of the at least two frequency bands.
A method of receiving broadcasting services using multiple frequency bands, the method comprising:
- receiving scheduling result information from a scheduler;
- scheduling a frequency band for each frame from a plurality of frames included in a single broadcasting data stream queue 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 scheduling result information is based on whether a frame comprises an infra frame (I-frame), a previous frame (P-frame), or a bidirectional frame (B-frame), and
- the scheduling is performed for a plurality of session queues, multiple frames in each session queue comprise different quality of service (QoS) requirements, and the multiple frames in each session queue are individually designated to the at least two frequency bands based on a quality of service requirement determined for each individual frame and based on differing qualities of the at least two frequency bands.
