A communication device for transmitting a Very High Throughput Signal Field B (VHT-SIG-B) is described. The communication device includes a processor and instructions stored in memory that is in electronic communication with the processor. The communication device allocates bits for the VHT-SIG-B in a backwards compatible preamble. The communication device additionally applies a pilot mapping for the VHT-SIG-B that is the same as a pilot mapping for the DATA field. The communication device further transmits the VHT-SIG-B.
