Resource unit (RU) allocation for downlink (DL) multi-block acknowledgement (M-BA) for uplink (UL) multiple user (MU) wireless communications

A wireless communication device comprising:

• a communication interface;
• and
• processing circuitry that is coupled to the communication interface, wherein at least one of the communication interface or the processing circuitry configured to:
• generate a first orthogonal frequency division multiple access (OFDMA) frame that specifies a plurality of resource units (RUs) to be used by a plurality of other wireless communication devices when transmitting a second OFDMA frame to the wireless communication device;
• transmit the first OFDMA frame to the plurality of other wireless communication devices;
• receive the second OFDMA frame from the plurality of other wireless communication devices based on the plurality of RUs specified within the first OFDMA frame, wherein the second OFDMA frame includes first information from a first of the plurality of other wireless communication devices modulated within a first of the plurality of RUs as specified in the first OFDMA frame, second information from a second of the plurality of other wireless communication devices modulated within a second of the plurality of RUs as specified in the first OFDMA frame, and third information from a third of the plurality of other wireless communication devices modulated within a third of the plurality of RUs as specified in the first OFDMA frame, wherein the second OFDMA frame includes an uplink (UL) multi-user (MU) PLCP Protocol Data Unit (PPDU), wherein PLCP corresponds to Physical Layer Convergence Procedure;
• and
• generate, based on receipt of the second OFDMA frame, a third OFDMA frame, wherein the third OFDMA frame includes a first response to the first information from the first of the plurality of other wireless communication devices modulated within a first RU that spans the first of the plurality of RUs, and a second response to both the second information from the second of the plurality of other wireless communication devices modulated and the third information from the third of the plurality of other wireless communication devices modulated within a second RU that spans the second of the plurality of RUs;
• and
• transmit the third OFDMA frame to the plurality of other wireless communication devices.

A method for execution by a wireless communication device, the method comprising:
