PAPR REDUCTION FOR DATA PORTION OF ENHANCED LONG RANGE PPDU

원문 (중국어)

Methods and apparatus are described for performing Enhanced Long Range (ELR) wireless communications. In a method, a wireless device generates an ELR physical layer protocol data unit (ELR PPDU), including generating a legacy preamble, an ELR preamble, and an ELR data portion including repeated ELR data. Generating the ELR data portion includes copying the ELR data in a plurality of Resource Units (RUs), including a first RU, a second RU, a third RU and a fourth RU. Generating the ELR data portion further includes partitioning each of the plurality of RUs, respectively, into a first RU portion and a second RU portion, and multiplying each of the first RU portions and second RU portions by a separate sequence entry of a masking sequence (e.g., [1 1 1 1 −1 1 1 −1]). The wireless device transmits the ELR PPDU over a wireless interface for reception by a second device.
