Repetition transmission method in a communication system

A method for wireless communication, comprising:

• transmitting, by a network device to a user device, a group configuration defining one or more groups for a plurality of uplink transmissions, each group in the one or more groups comprising one or more repetitions;
• transmitting a redundancy version (RV) configuration for the one or more repetitions in each of the one or more groups;
• and
• receiving, from the user device, the plurality of uplink transmissions based on the RV configuration by applying an orthogonal cover code to the one or more repetitions in each respective group.

A wireless communication apparatus comprising at least one processor and a memory, wherein the at least one processor is configured to cause the wireless communication apparatus to:

• receive a group configuration defining one or more groups for a plurality of uplink transmissions, each group in the one or more groups comprising one or more repetitions;
• receive a redundancy version (RV) configuration for the one or more repetitions in each of the one or more groups;
• and
• transmit the plurality of uplink transmissions based on the RV configuration and by applying an orthogonal cover code to the one or more repetitions in each respective group.
