Spatial pilot to support MIMO receivers in a multi-antenna and multi-layer transmission
communication system. A first layer pilot for a single layer transmission is repeated across …

Efficient pilot transmission schemes for multi-antenna com munication systems are
described. In general, MISO receiv ers prefer a pilot transmitted in one spatial direction, and …

A multi-antenna transmitting entity transmits data to a single-or multi-antenna receiving entity
using (1) a steered mode to direct the data transmission toward the receiving entity or (2) a …
