STAs may identify one of the two operation information fields based on capabilities of the STA (e.g., whether or not the STA is capable of dual band channel bonding, resource unit or physical channel puncturing, etc.). In some cases, one operation information field may indicate a channel width within a first and second frequency band (e.g., within the 5 GHz band and the 6 GHz band), as well as a puncturing scheme associated with the channel width. In some cases, the operation information field may indicate a dual band channel bonding configuration, where two frequency segments associated with the channel bonding configuration are in two different frequency bands. In some cases, a tightened spectral mask may be used for such dual band channel bonding configurations. ## Claims ### Claim 1 An apparatus for wireless communication, comprising: a processor, memory in electronic communication with the processor;
