1. A method performed by a wireless communication device comprising:
receiving, from a network node, information that configures the wireless communication device for a Configured Grant, CG, based Physical Uplink Shared Channel, PUSCH, transmission with PUSCH repetitions towards a first and a second transmissions/reception points, TRPs, wherein the first and second TRPs are respectively associated with first and second Sounding Reference Signal, SRS, resource set; and
performing the CG based PUSCH transmission with PUSCH repetitions towards the first and second TRPs at different PUSCH transmission occasions in accordance with the received information;
wherein:
the information that configures the wireless communication device further comprises:
a single Redundancy Version, RV, sequence configured for both of the two TRPs, wherein the RV sequence consists of four RV values comprising RV1, RV2, RV3, and RV4; and
a RV offset to be applied to the second TRP, wherein the RV offset comprises one of 0, 1, 2, or 3; and
the RV sequence is to be applied to PUSCH repetitions towards the first TRP starting with RV1 in the RV sequence to the first PUSCH transmission occasion to the first TRP, and the RV sequence is to be applied to PUSCH repetitions towards the second TRP starting with a RV in the RV sequence indicated by the RV offset to the first PUSCH transmission occasion to the second TRP.
