Method for transmitting and receiving signal in wireless communication system, and apparatus therefor

An user equipment (UE) for transmitting a uplink signal in wireless communication system, the UE comprising:

• a transceiver for transceiving a radio signal;
• and
• a processor connected to the transceiver,
• wherein the processor is configured 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 (ODD);
• 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, the 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 a size of a configured band.

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 (ODD);
• 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, the 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 a size of a configured band.

One or more non-transitory computer-readable media(CRM) storing one or more instructions, the one or more instructions comprising:

• receiving, from a base station, first control information related to a delay value which is applied to precoding for small-delay cyclic delay diversity (CDD);
• performing 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
• transmitting, to the base station, the 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 a size of a configured band.
