1. A method, comprising:
receiving a control frame; and
transmitting a control response frame responsive to receiving the control frame,
wherein either or both of a scrambling sequence and a SERVICE field of the control frame are set to indicate bandwidth and preamble puncturing information, and
wherein, in an event that the receiving and the transmitting are performed in a 6 GHz band:
at least six reserved bits of the plurality of reserved bits in the SERVICE field of the control frame are set to indicate a bandwidth and a multiple resource unit (MRU) or MRU pattern regarding preamble puncturing, and
at least six reserved bits of a plurality of reserved bits in a SERVICE field of the control response frame are set to indicate a bandwidth and an MRU or MRU pattern regarding preamble puncturing of the control response frame.
