A semiconductor device includes: a center region; a periphery region; and a semiconductor layer including pairs of a first region having a first impurity amount and a second region having a second impurity amount. The method includes receiving, from the N base stations, ACKNACK signals indicating transmission acknowledgement status for an uplink packet; and transmitting a packet according to the number of ACK signals. These heterocyclic compounds are in turn useful precursors for diverse pharmaceutical, herbicidal and insecticidal agents. For an insertion, a number of windings that corresponds at least approximately to the weft yarn section intended to be inserted is detached or set free from the support while maintaining its tubular configuration without yarn tension. A collision is detected between the first and second CSI reports.
