METHOD OF SHIFTING REDUNDANCY VERSION FOR THE TRANSMISSION OF A TRANSPORT BLOCK OVER MULTIPLE SLOTS
Where large transport blocks are rate-matched and transmitted on each PUSCH segment using different redundancy versions (RVs), RV cycling with a small number of PUSCH segments might not cover the whole codeword, and/or rate-matching a large TBS across many PUSCH segments into the resource of a single PUSCH segment may lead to an effective coding rate of the self-decodable redundancy versions that is too high. To avoid these issues, the starting position of one or more RVs may be shifted by setting the starting position of a current RV to be the same as an ending position of a previous position, or by scaling the starting position by a value. Alternatively, these issues may be avoided by setting a new starting position for an RV based on the gap from the end of a previous RV to the start of a current RV.

A method, apparatus, and computer program product modifying the usage of control resources for data transmission by focusing on reducing overhead of the control channel in order to maximize the spectral efficiency by configuring physical resources into two parts for an allocation into control information for the first part, and data for both the first part and the second part or data for only the second part. Data allocation in the first part based is derived based on the data allocation in the second part and the control information allocation in the first part. The number of control symbols within a subframe or transmission time interval is minimized on the downlink control signaling, used mainly for downlink and uplink grant signaling, and for the uplink HARQ ACK/NACK feedback.
