Title:
SYSTEMS AND METHODS FOR IMPROVEMENTS TO TRAINING FIELD DESIGN FOR INCREASED SYMBOL DURATIONS
Document Type and Number:
WIPO Patent Application WO/2015/171499
Kind Code:
A3
Abstract:
Methods, devices, and computer program products for improving training field design in packets with increased symbol durations are disclosed. In one aspect, a method of transmitting a packet on a wireless communication network is disclosed. The method includes transmitting a preamble of the packet over one or more space-time-streams, the preamble including one or more training fields configured to be used for channel estimation, the one or more training fields each comprising one or more symbols of a first symbol duration. The method further includes transmitting a payload of the packet over the one or more space-time-streams, the payload comprising one or more symbols of a second symbol duration, the second symbol duration greater than the first symbol duration.
