High-efficiency Wi-Fi (HEW) station and access point (AP) and method for signaling of channel resource allocations

A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors of an apparatus of a high-efficiency HE) access point (AP) to perform operations for communication, the operations to configure the one or more processors to:

• configure the HE AP to transmit a resource allocation message to indicate an allocation of channel resources for uplink transmissions by one or more HE stations;
• and
• configure the HE AP to receive one or more uplink transmissions from the HE stations according to the allocation, wherein the resource allocation message includes a resource distribution indicator to indicate whether the HE stations are allocated contiguous portions of the channel resources;
• wherein the channel resources include one or more sub-channels and an extra portion of frequency resources;
• and
• the resource allocation message further includes a sub-field for an extra portion indicator to indicate whether the extra portion of frequency resources is allocated to one of the HE stations, wherein the extra portion is in a center of the channel resources straddling a direct current (DC).

An apparatus of a high-efficiency (HE) station comprising:

• memory;
• and, hardware processing circuitry coupled to the memory, the hardware processing circuitry configured to:
• configure the HE station to receive, from an HE access point (AP), a resource allocation message to indicate an allocation of channel resources for transmission of uplink signals by the HEW station and one or more other HEW stations;
• and
• configure the HE station to transmit one or more uplink signals according to the allocation, wherein the resource allocation message includes a resource distribution indicator to indicate a contiguous allocation of the channel resources;
• wherein the channel resources include one or more sub-channels and an extra portion of channel resources;
• the sub-channels comprise a predetermined bandwidth and further comprise multiple sub-carriers;
• and
• the resource allocation message further includes a sub-field for an extra portion indicator to indicate whether the extra portion of channel resources is allocated, wherein the extra portion is in a center of the channel resources straddling a direct current (DC).
