Patent attributes
A wireless communication device (alternatively, device) includes a processor configured to support communications with other wireless communication device(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processor, among other possible circuitries, components, elements, etc. to support communications with other wireless communication device(s) and to generate and process signals for such communications. Different long training fields (LTFs) are designed using different respective binary sequences. The LTFs are designs based on a number of resource units (RUs) and RU sizes associated with a sub-carriers/tone plan. Each RU allocation specifies a respective one or more RUs of one or more RU sizes for a communication channel. The LTFs are designed such that peak to average power ratio (PAPR) of the LTF increases across the RU allocations as size of the one or more RU sizes increases.
