Wireless device, method, and computer-readable media for transmitting and receiving high-efficiency signal fields

A method for transmitting high-efficiency signal (HE-SIG) fields performed by an access point (AP), the method comprising:

• encoding a high-efficiency signal (HE-SIG) field for each of a plurality of sub-channels, wherein each encoded HE-SIG field for each sub-channel includes a common field and a sub-channel specific field;
• and
• simultaneously transmitting on each of the plurality of sub-channels, a corresponding encoded HE-SIG field as a preamble to a physical layer convergence protocol (PLCP) protocol data unit (PPDU), wherein the common field of the corresponding HE-SIG field comprises information of a format of the PPDU, and wherein the sub-channel specific field comprises information that allows HE devices that are operating on the sub-channel on which the HE-SIG field is transmitted to determine which portion of the PPDU to demodulate, wherein the sub-channel specific field further comprises a resource map field comprising a plurality of allocations, each allocation of the plurality of allocations includes the HE wireless device identification and an indication of a modulating and coding scheme (MCS), wherein a position of a HE wireless device identification within the resource map field indicates the position of a resource unit within a corresponding sub-channel, and wherein the resource unit is assigned to a HE wireless device identified by the HE wireless device identification.

A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors to perform operations for transmitting high-efficiency signal (HE-SIG) fields on an access point (AP), the operations to configure the AP to:

• encode a high-efficiency signal (HE-SIG) field for each of a plurality of sub-channels, wherein each encoded HE-SIG field for each sub-channel includes a common field and a sub-channel specific field;
• and
• simultaneously transmit on each of the plurality of sub-channels, a corresponding encoded HE-SIG field as a preamble to a physical layer convergence protocol (PLCP) protocol data unit (PPDU), wherein the common field of the corresponding HE-SIG field comprises information of a format of the PPDU, and wherein the sub-channel specific field comprises information that allows HE devices that are operating on the sub-channel on which the HE-SIG field is transmitted to determine which portion of the PPDU to demodulate, wherein the sub-channel specific field further comprises a resource map field comprising a plurality of allocations, each allocation of the plurality of allocations includes a HE wireless device identification and an indication of a modulating and coding scheme (MCS), wherein a position of the HE wireless device identification within the resource map field indicates the position of a resource unit within a corresponding sub-channel, and wherein the resource unit is assigned to a HE wireless device identified by the HE wireless device identification.
