Abstract: Apparatus, and an associated method, for facilitating resource allocation in a mobile communication system. Historical indicia associated with a mobile station is monitored and maintained. A predictor forms a prediction of a subsequent path of travel of the mobile station responsive to the historical indicia that is collected and maintained at the memory element. The predicted path of travel of the mobile station is utilized in the allocation of communication resources to the mobile station. Updates are made to the predicted path of travel, and reallocation of the communication resources is correspondingly made, thereby to efficiently utilize the communication resources available in the communication system.

Abstract: Apparatus, and an associated method, for communicating data pursuant to a frequency division multiplexing scheme that takes into account channel conditions on the communication channel upon which the data is communicated. Sub-bands are defined in which adjacent ones of the sub-bands overlap upon one another. When data parts of data communicated upon separate ones of the sub-bands are received at a receiving station, each sub-band is filtered by a first filter to pass signal parts within frequencies within each of the first sub-bands. Over sampling is performed upon each of the past signal parts at the separate sub-bands to frequency-shift interfering component parts thereof. Then, additional band pass filtering is performed to reject the interfering signal component portions. Subsequent processing is thereafter performed upon the data components.

Abstract: Apparatus, and associated method, for increasing the diversity levels of data communicated upon a channel susceptible to fading. Trellis-coded modulation is performed upon data to be communicated to form trellis-coded modulated and rotated symbols. Coordinate interleaving is performed by a coordinate interleaver upon selected ones of the modulated and rotated symbols. The coordinate interleaving is performed according to a selected coordinate interleaving scheme responsive to indications of channel conditions upon the communication channel. When delivered to a receiving station, a coordinate deinterleaver deinterleaves the interleaved symbols according to a coordinate deinterleaving scheme that corresponds to the coordinate interleaving scheme.

Abstract: Apparatus, and an associated method, for facilitating selection of optimal antenna weightings by which to weight signals sent in a communication system that utilizes closed-loop transmit diversity. A deterministic perturbation gradient approximation technique is utilized in which perturbation vectors are selected by a selector and applied, by an applicator, to antenna weighting elements. A selected set of perturbation vectors are applied to the antenna weighting elements in both a positive direction and a negative direction. A detector at a receiving station measures in disassociated with the signals communicated thereto, once weighted with the perturbation vectors. A single-bit feedback value is returned to the sending station, and the antenna weightings are appropriately adjusted. The technique is utilized during both non-handoff conditions and during handoff conditions.

A result of M antenna diversity may be achieved for M transmit antennas.
