US 2024/0259059 A1 · BEAM TRAINING TECHNIQUES IN WIFI FREQUENCY BANDS

Abstract

Methods, systems, and devices for wireless communications are described. A first wireless device (e.g., station (STA), access point (AP)) may transmit to a second wireless device during a service period, an initiating frame using a transmit beam that is based on a first beam training procedure performed between the devices prior to the service period. The first wireless device may perform a second beam training procedure during the service period based on an absence of a response frame from the second wireless device, based on an indication within the response frame received from the second wireless device, or based on identification of a change in a wireless channel relative to a previous beam training interval or previous service period. The first wireless device may then communicate one or more messages with the second wireless device using one or more beams that are based on the second beam training procedure.

Dependent claims

A first wireless device for wireless communication, comprising:

one or more memories storing processor-executable code;
and
one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the first wireless device to:
transmit, to a second wireless device during a service period, an initiating frame using a transmit beam;
perform a beam training procedure during the service period based at least in part on an absence of a response frame from the second wireless device;
and
communicate one or more messages with the second wireless device using one or more beams based at least in part on the beam training procedure.
