Communication overhead reduction apparatus, systems, and methods

摘要

An apparatus and a system, as well as a method and article, may operate to transmit a first number of training symbols corresponding to a first number of communication chains to solicit a response including a second number of training symbols corresponding to a second number of communication chains. The first and second number of communication chains may form a portion of a multiple-input, multiple-output (MIMO) system.

主权项

1. A method, comprising:
transmitting, by a first device to a second device, a request to transmit packet having a first number of training symbols corresponding to a number of antennas used by the first device; and receiving, at the first device from the second device, a clear to send packet having a second number of training symbols corresponding to a number of antennas used by the second device; wherein the exchange of the request to send packet and the first number of training symbols corresponding to the number of antennas used by the first device and the clear to send packet and second number of training symbols corresponding to a number of antennas used by the second device is performed without channel state information (CSI) feedback between the first device and the second device.
