Abstract: A base station (105) includes a scheduler (220) to determine a location of a user terminal (110) within a cell (125) of a wireless system (100). The cell has a cell boundary (125). The scheduler (220) also determines a subcarrier frequency diverse resource allocation for a call on the user terminal (110) in response to the location of the user terminal (110) being within a predetermined distance from an edge of the cell boundary (125). The scheduler (220) further determines a subcarrier frequency selective resource allocation for the call on the user terminal (110) in response to the location of the user terminal (110) being beyond a predetermined distance from the edge of the cell boundary. The base station (105) also includes a transceiver (215) to transmit the call according to the subcarrier frequency diverse resource allocation and the subcarrier frequency selective resource allocation.

Abstract: A method and apparatus for interleaving within a communication system is provided herein. More particularly parameters for a convolutional turbo code interleaver are provided, and interleaving takes place utilizing the new parameters. The new parameters generate interleavers that have the correct turbo code behaviors of improving performance with increasing block size and an error floor well below a block error rate of 10?4. Furthermore, the parameters have no implementation impact. Interleaving in accordance with the preferred embodiment of the present invention can achieve a block error rate of 10?4 at a signal-to-noise ratio that is at least 0.5 dB, and in some cases up to 1.3 dB, smaller than that which can be achieved with the code using the existing parameters.

Abstract: A method and apparatus for pilot signal transmission is disclosed herein. In particular, a pilot transmission scheme is utilized where pilot sub-carrier bandwidth differs from data sub-carrier bandwidth. Because some user's data sub-carriers will no longer have the user's pilot sub-carriers adjacent to them, the set, or pattern of sub-carriers used by the pilot blocks changes at least once in a burst. Changing the pilot block pattern (the set of occupied pilot block sub-carriers) at least once in the burst serves to increase the frequency proximity of occupied data sub-carriers to occupied pilot sub-carriers in the burst.

Abstract: A pilot transmission scheme is presented where during a first OFDM symbol period a first pilot sequence is transmitted over a first multiple sub-carriers on a first group of antennas. During a second OFDM symbol period, a second pilot sequence is transmitted over a second multiple sub-carriers on a second group of antennas. The first and the second groups of antennas only transmit one pilot sequence every subframe of M OFDM symbol periods.
