Systems and methods for improvements to training field design for increased symbol durations

摘要

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, wherein the one or more symbols of the second symbol duration are each separated from each other by a cyclic prefix of a third duration, and wherein the first symbol duration is determined based at least in part on the third duration.
