Format of VHT-SIG-B and service fields in IEEE 802.11AC

摘要

Methods and apparatus for transmitting and receiving frames with various Very High Throughput Signal B (VHT-SIG-B) and Service field formats are provided. Some of these formats may be in accordance with the IEEE 802.11ac amendment to the wireless local area network (WLAN) standard.

主权项

1. A method for wireless communications, comprising:
generating a frame having a preamble portion and a data portion, wherein the preamble portion comprises a Very High Throughput Signal B (VHT-SIG-B) field indicating a length of useful data in the data portion and wherein both the VHT-SIG-B field and the data portion use the same number of subcarriers; applying power scaling to the frame to keep total power of the VHT-SIG-B field equal to total power of a preamble training field while allowing per-tone power of the VHT-SIG-B field to differ from per-tone power of the preamble training field; and transmitting the generated frame.
