The subframe structure can include a plurality of subframes each having a subframe duration. The method can include operating a serving cell on a carrier frequency. The method can include performing a LBT on the carrier frequency for a time duration that at least partially overlaps a terminal portion of a subframe duration of a first subframe of the plurality of subframes. The method can include determining a position of a starting OFDM symbol for transmitting a control channel in a second subframe of the plurality of subframes based on the time duration of the LBT. The subframe duration of the second subframe can occur immediately after the subframe duration of the first subframe."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for reception and transmission of control channels","description":"A method for a base station can create a subframe structure used in communication between the base station and a UE.
