US 2023/0069075 A1 · DISTRIBUTED TRANSMISSION OF SHORT TRAINING FIELDS

Abstract

This disclosure provides methods, devices and systems for distributed transmission of short training fields in a power spectral density limited frequency band. In one aspect, a device receives a distributed resource unit (dRU) assignment for transmission of a dRU portion of a physical layer protocol data unit (PPDU); determines a spatial stream global cyclic shift delay (CSD) index for an short training field (STF) of the dRU portion of the PPDU; and transmits, based on the spatial stream global CSD index, the EHT of the dRU portion of the PPDU across a dRU spreading bandwidth associated with the dRU assignment using a tone plan and sequence corresponding to a regular resource unit (rRU) transmission mode.

Dependent claims

A method of wireless communication by a wireless communication device, comprising:

receiving a distributed resource unit (dRU) assignment for transmission of a dRU portion of a physical layer protocol data unit (PPDU);
determining a spatial stream global cyclic shift delay (CSD) index for a short training field (STF) of the dRU portion of the PPDU;
and
transmitting, based on the spatial stream global CSD index, the STF of the dRU portion of the PPDU across a dRU spreading bandwidth associated with the dRU assignment using a tone plan and sequence corresponding to a regular resource unit (rRU) transmission mode.
