Abstract

This disclosure describes systems, methods, and devices related to using enhanced high efficiency (HE) frames. A device may determine a high efficiency signal-B (HE-SIG-B) field for a high efficiency (HE) frame, the HE-SIG-B field comprising a common information field and a user information field. The device may determine a data portion of the HE frame, wherein the data portion includes one or more resource units (RUs) with a size equal to a number of tones. The device may determine a first resource allocation subfield and a second resource allocation subfield of the common information field based at least in part on the number of tones. The device may cause to send the HE frame.

generate a first indication of the first RU allocation, the first indication consisting of a first eight bits, wherein each of the first eight bits indicate the first RU allocation;
generate a second indication of a second RU allocation in the channel and subsequent in time to the first RU allocation, the second indication consisting of a second eight bits whose value is equal to decimal 115 , wherein each of the second eight bits indicate the second RU allocation;
generate a high efficiency signal-B (HE-SIG-B) field for a high efficiency (HE) frame, the HE-SIG-B field comprising a common information field, the common information field comprising the first indication of the first RU allocation and the second indication of the second RU allocation; and
send the HE frame to the station device.

3. The device of claim 1 , wherein the processing circuitry is further configured to:
encode a first user information field subsequent to the common information field in the HE-SIG-B field, the first user information field comprising an indication of the station device; and
based on the first RU allocation comprising the first 996 tones, refrain from encoding a second user information field in the HE-SIG-B field.

4. The device of claim 1 , wherein the first RU allocation comprises an orthogonal frequency-division multiple access (OFDMA) 996-tone RU and a multi-user multiple input, multiple output (MU-MIMO) 996-tone RU.

5. The device of claim 1 , wherein the first RU allocation is based at least in part on a number of station device user information fields included in the RU.

6. The device of claim 1 , wherein a first HE-SIG-B field is associated with first HE-SIG-B content channel and a second HE-SIG-B field is associated with a second content channel.

7. The device of claim 1 , wherein a value of the first eight bits of the first RU allocation indicates on a number of user information fields signaled in the first RU allocation.
