Methods, Devices and Systems for Initial Grant-Free Transmission Determination

A user equipment (UE), the UE comprising:

• a processor;
• and
• a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
• receive a resource configuration for grant-free (GF) transmissions, wherein the resource configuration comprises a periodicity parameter (P), a repetition number (K), and a sequence of redundancy version (RV) numbers corresponding to one or more RV types, the periodicity parameter defines a period having K transmission occasions (TOs), and each of the K TOs is associated with one RV number in the sequence of RV numbers;
• and
• perform an initial GF transmission of data in a TO of the K TOs in the period defined by the periodicity parameter, the TO associated with an RV number corresponding to RV0.

• receive a resource configuration for grant-free (GF) transmissions, wherein the resource configuration comprises a periodicity parameter (P), a repetition number (K), and a sequence of redundancy version (RV) numbers comprising {0, 2, 3, 1}, 0 in the sequence corresponding to RV0, a in the sequence corresponding to RV1, 2 in the sequence corresponding to RV2, and 3 in the sequence corresponding to RV3, the periodicity parameter defines a period having K transmission occasions (TOs), and each of the K TOs is associated with one RV number in the sequence of RV numbers;
• and
• perform an initial GF transmission of data in a TO of the K TOs in the period defined by the periodicity parameter using an RV corresponding to an RV number in the sequence of RV numbers, the RV based on a size of the sequence of RV numbers and a position of the TO in the K TOs.
