Response time relaxation for high efficiency WLAN

摘要

Aspects of the present disclosure relate to techniques for generating responses to extended length frames having increased symbol lengths without changing the short interframe space duration. According to certain aspects, a method for transmitting an extended length frame generally includes generating a packet having a preamble decodable by a first type of device having a first set of capabilities and a second type of device having a second set of capabilities, wherein at least a first portion of the packet is generated using an increased symbol duration or increased cyclic prefix relative to a second portion of the packet generated using a standard symbol duration or standard cyclic prefix and the packet includes padding symbols after the first portion, and outputting the generated packet for transmission.

主权项

1. An apparatus for wireless communications, comprising:
a processing system configured to:
generate a packet having a preamble decodable by a first type of device having a first set of capabilities and a second type of device having a second set of capabilities, wherein at least a first portion of the packet is generated using an increased symbol duration or increased cyclic prefix relative to a second portion of the packet generated using a standard symbol duration or standard cyclic prefix and the packet includes one or more padding symbols after the first portion; and a transmit interface configured to output the generated packet for transmission.
