PHYSICAL LAYER PREAMBLE DESIGN FOR SPECIAL PACKET TYPES - A simplified explanation of the abstract

This abstract first appeared for US patent application 18463197 titled 'PHYSICAL LAYER PREAMBLE DESIGN FOR SPECIAL PACKET TYPES

Abstract

This patent application describes methods, devices, and systems for generating packet preambles. It specifically focuses on special cases such as full-bandwidth multi-user multiple-input multiple-output (MU-MIMO), single-user (SU) preamble puncturing, hybrid automatic repeat request (HARQ), and multi-AP coordination. The multi-AP coordination can include coordinated beamforming (CoBF), joint transmission (JT), or coordinated orthogonal frequency division multiple access (C-OFDMA). The patent also covers preamble designs that accommodate signal fields of different cases.

Bullet Points

• Methods, devices, and systems for generating packet preambles are disclosed.

Original Abstract Submitted

This disclosure provides methods, devices and systems for generating packet preambles. Some implementations more specifically relate to preamble designs for special cases such as, for example, full-bandwidth multi-user multiple-input multiple-output (MU-MIMO), single-user (SU) preamble puncturing, hybrid automatic repeat request (HARQ), and multi-AP coordination. Multi-AP coordination may refer to coordinated beamforming (CoBF), joint transmission (JT), or coordinated orthogonal frequency division multiple access (C-OFDMA). Additionally, or alternatively, some implementations more specifically relate to preamble designs that accommodate signal fields of different cases.
