VHT-SIG-B FIELD IN NULL DATA PACKETS (NDPs) |
摘要 |
Certain aspects of the present disclosure relate to methods and apparatus for using information in a Very High Throughput Signal B (VHT-SIG-B) field in the preamble of a null data packet (NDP). Retaining the VHT-SIG-B field in NDPs offers several advantages, such as maintaining a unified IEEE 802.11ac preamble structure, providing for 4 μs extra time to process beamforming feedback, and being able to use information in the VHT-SIG-B field to determine a level of interference in the NDP. |
