Technologies are generally presented for a relay forwarding system combining a data efficiency of soft forwarding that increases generalized signal-to-noise ratio with the ability to use hybrid-automatic repeat requests substantially high throughput levels may be maintained by using repair instead of packet re-requests. A heterocyclic compound represented by the formula wherein each symbol is as defined in the specification, or a salt thereof. In such a case, the event management system can be configured to respond to such similarly configured events in similar ways. When the count data signal indicates a value k, k-th output circuit of the M output circuits converts the first to N-th output signals to a first to N-th scanning signals, respectively, and outputs them to N scan electrodes of a display panel in order, respectively.
