Abstract

Methods and apparatuses for communicating over a wireless communication network are disclosed herein. One example apparatus includes a memory that stores instructions. The apparatus further includes a processor coupled with the memory. The processor and the memory are configured to determine a total bandwidth for a transmission of a message, the total bandwidth including a plurality of tones. The processor is further configured to divide the plurality of tones in the total bandwidth into one or more 26-, 52-, 106-, 242-, or 996-tone blocks. The processor is further configured to determine an indication. The indication assigns one or more of the one or more tone blocks to a first wireless communication device. The apparatus further includes a transmitter configured to transmit the indication to at least the first wireless communication device or a second device.

First claim

What is claimed is:

1 . An apparatus for wireless communication, comprising:
a memory that stores instructions; a processor coupled with the memory, wherein the processor and the memory are configured to:
determine a total bandwidth for a transmission of a message, the total bandwidth comprising a plurality of tones;
divide the plurality of tones in the total bandwidth into one or more 26-, 52-, 106-, 242-, or 996-tone blocks; and
determine an indication, the indication assigning one or more of the one or more tone blocks to a first wireless communication device; and
a transmitter configured to transmit the indication to at least the first wireless communication device or a second device.

2 . The apparatus of claim 1 , wherein the message comprises, for transmission over a 20 MHz bandwidth, at least one of:
6 left edge tones, followed by 1 unallocated tone, followed by two 26-tone blocks, followed by 1 unallocated tone, followed by two 26-tone blocks, followed by 13 tones of a split 26-tone block, followed by 7 direct current (DC) tones, followed by 13 tones of the split 26-tone block, followed by two 26-tone blocks, followed by 1 unallocated tone, followed by two 26-tone blocks, followed by 1 unallocated tone, followed by 5 right edge tones; 6 left edge tones, followed by 1 unallocated tone, followed by one 52-tone block, followed by 1 unallocated tone, followed by one 52-tone block, followed by 13 tones of a split 26-tone block, followed by 7 DC tones, followed by 13 tones of the split 26-tone block, followed by one 52-tone block, followed by 1 unallocated tone, followed by one 52-tone block, followed by 1 unallocated tone, followed by 5 right edge tones; 6 left edge tones, followed by a 106-tone block, followed by 13 tones of a split 26-tone block, followed by 7 DC tones, followed by 13 tones of the split 26-tone block, followed by a 106-tone block, followed by 5 right edge tones; and 6 left edge tones, followed by a 121 tones of a split 242-tone block, followed by 3 DC tones, followed by a 121 tones of the split 242-tone block, followed by 5 right edge tones.

3 . The apparatus of claim 1 , wherein the message comprises, for transmission over a 40 MHz bandwidth, at least one of:
