1. A method performed by a wireless device for transmitting data to multiple Transmission/Reception Points, TRPs, the method comprising:
receiving control information for scheduling a multi-TRP transmission, the control information comprising an indication of a gap between each TRP transmission and a redundancy version identifier;
transmitting the data to a first TRP according to the control information;
after the gap, transmitting the data to a second TRP according to the control information; and
applying a Redundancy Version, RV, offset to the multi-TRP transmission in accordance with a received configuration;
wherein:
a redundancy version applied to the data transmitted to the first TRP is in accordance with the redundancy version identifier comprised in the control information; and
a redundancy version applied to the data transmitted to the second TRP is in accordance with the redundancy version identifier comprised in the control information and the RV offset.
