Uplink-based wireless radio resource management

摘要

Presented herein are techniques for using uplink transmissions from devices (e.g., wireless tags, clients, etc.) to determine a path loss between neighboring access points. In one example, a wireless controller obtains receive signal strength information of uplink transmissions received at neighboring access points in a wireless network. The wireless controller determines an effective path loss between the neighboring access points based on the receive signal strength information for the uplink transmissions received at the neighboring access points. The wireless controller also performs radio resource management operations in the wireless network using the effective path loss determined based on the uplink transmissions received at the neighboring access points.

1. A method comprising:
obtaining, at a wireless controller, receive signal strength information of uplink transmissions sent from a first client to first and second neighboring access points in a wireless network, and receive signal strength information of neighbor messages transmitted between the first and second neighboring access points; determining, at the wireless controller, an estimated path loss between the first and second neighboring access points using the receive signal strength information obtained from the uplink transmissions sent from the first client to the first and second neighboring access points; determining, at the wireless controller, a measured path loss between the neighboring access points using the receive signal strength information obtained from the neighbor messages transmitted between the first and second neighboring access points; determining, at the wireless controller, an effective path loss between the first and second neighboring access points based at least on the estimated path loss and the measured path loss; and performing, at the wireless controller, radio resource management operations in the wireless network using the effective path loss.
