Abstract  Abstract

The user terminal supports a number of spatial multiplexing (SM) modes, such as a maneuvering mode and a non-steering mode. In data transmission, multiple data streams are encoded and modulated according to a selected rate to obtain multiple data symbol streams. These data streams are then spatially processed according to the selected SM mode (eg, using a matrix of steering vectors in maneuvering mode, and using an identity matrix in non-steering mode) to produce a number of Obtain multiple transmit symbol streams for transmission from the antenna. For data reception, multiple received symbol streams are spatially processed according to the selected SM mode (eg, using a matrix of eigenvectors in pilot mode and using a spatial filter matrix in non-pilot mode) Obtain a recovered data symbol stream. These streams are demodulated and decoded according to the selected rate to obtain a number of decoded data streams.
