Title:
METHOD AND APPARATUS FOR FREQUENCY SELECTIVE UL PRECODING
Document Type and Number:
WIPO Patent Application WO/2022/255846
Kind Code:
A1
Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Apparatuses and methods for frequency selective uplink precoding are provided. The method includes receiving configuration information about resource allocation for an uplink transmission, the configuration information indicating: allocated resources for uplink transmission, and uplink precoding information for G antenna port groups for the uplink transmission on the allocated resources, wherein the uplink precoding information indicates: SD basis vectors, FD basis vectors, coefficients for (SD, FD) basis vector pairs, and two components for the coefficients across the G antenna port groups; based on the uplink precoding information, applying uplink precoding for the G antenna port groups; and performing uplink transmission on the allocated resources according to the configuration information.
