METHOD AND APPARATUS FOR PRECODER DETERMINATION AND PRECODER MATRIX INDICATOR (PMI) INDICATION FOR UPLINK TRANSMISSION

Abstract:

Provided herein are method and apparatus for precoder determination and precoder matrix indicator (PMI) indication for uplink transmission. The disclosure provides an apparatus for a user equipment (UE), comprising circuitry configured to: determine a precoder for each of a plurality of precoder resource block groups (PRGs) for an uplink transmission, wherein the plurality of PRGs are configurable in at least one of PRG size and number; and precode each of the plurality of PRGs with a determined precoder; and a memory to store the determined precoder for each of the plurality of PRGs.
