Abstract: Novel intron fragments are provided. The intron fragments can increase gene expression to levels equal to or higher than those achieved by the full-length intron while maintaining their ability to increase gene expression even when combined with various types of promoters and splicing donors. Particularly, the intron fragments enable loading of larger transgenes when used in genetic information delivery systems whose size is limited, for example, adeno-associated viruses (AAVs) and rhabdoviruses. Therefore, the use of the intron fragments is expected to extend the range of therapeutic genes.

Abstract: A method is provided for performing data transmission using a hybrid automatic repeat request (HARQ) scheme performed by a transmitter. The transmitter transmits uplink data to a receiver, and receives an acknowledgement (ACK) signal for the data from the receiver. The transmitter determines whether or not an uplink grant associated with the ACK signal is received. The transmitter keeps the uplink data in an HARQ buffer of the transmitter without flushing the uplink data if it is determined that the uplink grant associated with the ACK signal is not received within a certain time period from the receiver.
