Redundancy Version Selection Based on Receiving Quality and Transport Format

A method, in a base station, for transmitting a transport block to a user equipment in a communications network, the transport block comprising a plurality of bits, the method comprising:

• receiving information about a reception quality from the user equipment;
• selecting a transport format based on the reception quality;
• dynamically selecting, for a first transmission, a first redundancy version parameter for the reception quality based on a decoding performance for the transport block;
• transmitting, in a first transmission, to the user equipment the transport block with the plurality of bits distributed according to the selected first redundancy version parameter and according to the selected transport format.

A base station for transmitting a transport block to a user equipment in a communications network, the transport block comprising a plurality of bits, the base station configured to receive information about a reception quality from the user equipment;

• the base station comprising:
• one or more processing circuits configured to function as a selector configured to:
• select a transport format based on the reception quality;
• and
• dynamically select, for a first transmission, a first redundancy version parameter for the reception quality based on a decoding performance for the transport block;
• a transmitter configured to transmit, in a first transmission to the user equipment, the transport block with the plurality of bits distributed according to the selected first redundancy version parameter and according to the selected transport format.
