Abstract
A method and apparatus for subcarrier selection for systems is described. In one embodiment, a method for subcarrier selection for a system employing orthogonal frequency division multiple access (OFDMA) comprises partitioning subcarriers into groups of at least one cluster of subcarriers, receiving an indication of a selection by the subscriber of one or more groups in the groups, and allocating at least one cluster in the one or more groups of clusters selected by the subcarrier for use in communication with the subscriber.
Claims31
A method for subcarrier selection for a system employing orthogonal frequency division multiple access (OFDMA) comprising:
- partitioning subcarriers into a plurality of groups of at least one cluster of subcarriers;
- and
- receiving an indication of a selection by the subscriber of one or more groups in the plurality of groups;
- and
- allocating at least one cluster in the one or more groups of clusters selected by the subcarrier for use in communication with the subscriber.
A cellular network using OFDMA channels for communication, the network comprising:
- a plurality of cells, each of the plurality of cells having a plurality of sectors;
- a base station in each of the plurality of cells, wherein each base station allocates a first portion of OFDMA channels in a first portion of the plurality of sectors and a second portion of the OFDMA channels in a second portion of the plurality of sectors.
A cellular network using OFDMA channels for communication, the network comprising:
- a plurality of cells;
- a base station in each of the plurality of cells, wherein each base station allocates groups of clusters based on priorities assigned to different cluster groups based on the cell of the plurality of cells in which said each base station resides.
