Abstract:
A method of handling a barred cell in a wireless communication system is disclosed. The method of handling a barred cell in a user equipment using a plurality of frequencies includes releasing a Radio Resource Control (RRC) connection between the user equipment and a network if authentication between the user equipment and the network fails, and regarding a cell having a first uplink radio link and a first downlink radio link, a cell having only a second uplink radio link and a cell having only a second downlink radio link as barred cells, if the RRC connection is released.
Abstract:
Disclosed is a method for fabricating a GaN semiconductor epitaxial layer. The method includes the steps of: (a) providing a substrate within a reaction furnace; (b) setting a temperature range of the substrate to be 200° C.˜1,300° C.; (C) supplying a Ga metallic source on the substrate; (d) changing the supplied Ga metallic source on the substrate, to Ga metal islands; (e) supplying a nitrogenous source to the Ga metal islands after suspending supply of the Ga metallic source; (f) forming GaN islands by reacting the Ga metal islands with the nitrogenous source; and (g) growing a GaN epitaxial layer by basing the GaN islands as a seed.
