Patent ID: 8472424

Claim:
An apparatus for wireless transmission in HRPD communication that supports spatial techniques, determines time frequency resources available for OFDM and excludes time frequency resources used for traffic data and signaling sent with CDM, comprising: a) at least one processor to: determine time frequency resources available for orthogonal frequency division multiplexing (OFDM) and excluding time frequency resources used for traffic data and signaling sent with code division multiplexing (CDM) using a slot structure that is backward compatible with existing terminals; assign the time frequency resources available for OFDM to at least one terminal and exchanges data with each terminal via the time frequency resources assigned to that terminal; partitions the time frequency resources available for OFDM into multiple tiles, each tile corresponding to a block of tile frequency resources; assign at least one of the multiple tiles to at least one terminal; process OFDM symbols based on multiple OFDM symbol numerologies used in a traffic interval in HRPD to embed OFDM data in an HRPD waveform for each tile assigned to the at least one terminal; and b) a memory coupled to the at least one processor.
