Assignee: LG ELECTRONICS INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 13:
14. An apparatus comprising one or more memories and one or more processors operatively coupled to the one or more memories, the apparatus comprising:
wherein the one or more processors control the apparatus to:
receive, from a base station, first control information related to a delay value which is applied to precoding for small-delay cyclic delay diversity (CDD);
perform layer mapping complex-valued modulation symbol to at least one transmission layer;
perform the precoding, based on a precoding matrix and a diagonal matrix, for transmitting complex-valued modulation symbol on each transmission layer on an antenna port; and
transmit, to the base station, an uplink signal,

wherein the diagonal matrix is determined based on the delay value, and
wherein the delay value is determined based on the first control information and second control information which is determined based on a size of a configured band.
