用于生成和处理物理层数据单元的方法和用于通信的装置
Abstract:
生成用于PHY数据单元的第一部分的正交频域复用(OFDM)符号的第一集合以及用于PHY数据单元的第二部分的OFDM符号的第二集合。使用第一OFDM音调间距生成第一集合中的OFDM符号。使用不同于第一音调间距的第二音调间距生成第二集合中的至少一些OFDM符号。基于第一音调间距和第二音调间距来确定指示PHY数据单元的持续时间的长度指示符的值。生成PHY数据单元的第一部分以包括(i)OFDM符号的第一集合和(ii)被设置为确定值的长度指示符。生成PHY数据单元的第二部分以包括OFDM符号的第二集合。
Abstract(English):

A first set of orthogonal frequency domain multiplexing (OFDM) symbols for a first portion of a PHY data unit and a second set of OFDM symbols for a second portion of the PHY data unit are generated. OFDM symbols of the first set are generated with a first OFDM tone spacing. At least some OFDM symbols of the second set are generated with a second tone spacing different from the first tone spacing. A value for a length indicator indicative of a duration of the PHY data unit is determined based on the first tone spacing and the second tone spacing. The first portion of the PHY data unit is generated to include (i) the first set of OFDM symbols and (ii) the length indicator set to the determined value. The second portion of the PHY data unit is generated to include the second set of OFDM symbols.
