Abstract
Techniques for efficiently sending data in a wireless communication system are described. Time frequency resources available for orthogonal frequency division multiplexing (OFDM), which exclude time frequency resources used for traffic data and signaling sent with code division multiplexing (CDM), may be determined. The time frequency resources available for OFDM may be partitioned into multiple tiles. Each tile may be defined based on multiple OFDM symbol numerologies and may have a non-rectangular shape. Each terminal may be assigned at least one tile. A pilot pattern may be selected for each terminal from among multiple pilot patterns, which may support different delay spreads, spatial ranks, etc. Data and pilot may be exchanged with each terminal via the time frequency resources in the at least one tile assigned to the terminal. OFDM symbols may be processed based on multiple OFDM symbol numerologies for each assigned tile.
