Abstract:
Apparatus and methods for rate prediction in a wireless communication system having fractional frequency reuse are disclosed. A wireless communication system implementing Orthogonal Frequency Division Multiple Access (OFDMA) can implement a fractional frequency reuse plan where a portion of carriers is allocated for terminals not anticipating handoff and another portion of the carriers is reserved for terminals having a higher probability of handoff. Each of the portions can define a reuse set. The terminals can be constrained to frequency hop within a reuse set. The terminal can also be configured to determine a reuse set based on a present assignment of a subset of carriers. The terminal can determine a channel estimate and a channel quality indicator based in part on at least the present reuse set. The terminal can report the channel quality indicator to a source, which can determine a rate based on the index value.
