METHOD AND APPARATUS FOR TRANSMITTING WIRELESS LOCAL AREA NETWORK DATA - A simplified explanation of the abstract

This abstract first appeared for US patent application 17948871 titled 'METHOD AND APPARATUS FOR TRANSMITTING WIRELESS LOCAL AREA NETWORK DATA

Simplified Explanation

The method described in the patent application involves the construction of a radio frame by an access point (AP) within a scheduling window. The radio frame includes a preamble part compatible with an existing IEEE 802.11 legacy preamble, a preamble part used in a next-generation IEEE 802.11 standard (HEW preamble), and the first downlink subframe (DL subframe). The AP sends the legacy preamble, HEW preamble, and the first DL subframe in the radio frame. It then receives at least one uplink subframe (UL subframe) triggered by a DL subframe located before it.

  • The method involves constructing a radio frame with multiple preamble parts and a DL subframe.
  • The AP sends the legacy preamble, HEW preamble, and the first DL subframe in the radio frame.
  • It receives at least one UL subframe triggered by a DL subframe located before it.

Potential Applications

  • This method can be applied in wireless communication systems that use the IEEE 802.11 standard.
  • It can be used to improve the efficiency and performance of next-generation wireless networks.

Problems Solved

  • The method solves the problem of compatibility between existing IEEE 802.11 legacy systems and next-generation systems.
  • It addresses the need for efficient scheduling and communication between APs and devices in wireless networks.

Benefits

  • The method allows for the coexistence of legacy and next-generation systems within the same radio frame.
  • It enables improved performance and efficiency in wireless communication systems.
  • The method provides a seamless transition from legacy systems to next-generation systems.


Original Abstract Submitted

A method comprises constructing, by an access point (AP), a radio frame within a scheduling window, the radio frame including at least a preamble part compatible with an existing IEEE 802.11 preamble legacy preamble, a preamble part used in a next-generation IEEE 802.11 standard (HEW preamble), and the first downlink subframe (DL subframe); sending the Legacy preamble, the HEW preamble and the first DL subframe in the radio frame; receiving at least one uplink subframe (UL subframe) located after the first DL subframe; wherein each of the at least one UL subframes is triggered by one DL subframe located before the UL subframe.
