Abstract: A radio transmission apparatus and a radio transmission method for readily controlling retransmission timing presets a frame cycle for retransmission, and transmits only packets for which no acknowledgement of receipt has been received within the frame cycle as a reply from a receiving apparatus to a transmitting apparatus. Thus, timing for retransmission can be readily determined. Also, the retransmission timing is determined based on when a packet is actually transmitted. Therefore, the multiple acknowledgement of receipt can be returned as a combined reply.

Abstract: Physical layer characteristics, e.g., reference signal density, reference signal distribution, data parameters, etc., are defined in the physical layer for sub-frames of a transmission time interval (TTI) allocated to data packet(s) based on the number of allocated sub-frames. The flexibility provided by the solution presented herein enables the associated wireless system to better define those physical layer characteristics necessary to meet signal quality and system requirements without unnecessarily overburdening the system overhead. Thus, the reference signal overhead may be reduced, which leads to reduced system overhead and/or increased spectrum efficiency.
