Signaling resource allocations in multi-user data units

摘要

A physical layer (PHY) preamble of a multi-user (MU) PHY data unit is generated. The PHY preamble is generated to include formatting information regarding the MU PHY data unit, including a field to be transmitted within a first individual communication channel among a plurality of individual communication channels that collectively span a bandwidth of a composite channel, each individual communication channel including a plurality of basic resource allocation (RA) units that collectively span a bandwidth of the individual communication channel. The field is generated to indicate one or more groupings of basic RA units, wherein at least one of the one or more groupings of basic RA which includes basic RA units of one or more other individual communication channels. A data portion of the MU PHY data unit is generated according to the formatting information in the PHY preamble, and the MU PHY data unit is generated to include the PHY preamble and the data portion.

1. A method for generating multi-user (MU) physical layer (PHY) data unit for transmission via a composite communication channel that comprises a plurality of individual communication channels that collectively span a bandwidth of the composite communication channel, wherein each individual communication channel includes a plurality of basic resource allocation (RA) units that collectively span a bandwidth of the individual communication channel, the method comprising:
generating, at a communication device, a PHY preamble that includes formatting information regarding the MU PHY data unit, including generating a field of the PHY preamble to be transmitted within a first individual communication channel among the plurality of individual communication channels, wherein the field is generated to indicate one or more groupings of basic RA units, wherein at least one of the one or more groupings of basic RA units includes basic RA units of one or more other individual communication channels; generating, at the communication device, a data portion of the MU PHY data unit according to the formatting information in the PHY preamble; and generating, at the communication device, the MU PHY data unit to include the PHY preamble and the data portion.
